                        TO BE HELD ON OCTOBER 10, 1996

                              GENERAL INFORMATION
 
  This Proxy Statement is being furnished to the shareholders of Plasma &
Materials Technologies, Inc., a California corporation ("PMT"), in connection
with the solicitation by its Board of Directors of proxies to be used at the
1996 Annual Meeting of its shareholders (the "Annual Meeting") to be held on
Thursday, October 10, 1996 at 10:00 a.m., local time, at the Warner Center
Marriott located at 21850 Oxnard Street, Woodland Hills, California 91367, and
any adjournment or postponement thereof. This Proxy Statement and the form of
proxy utilized at the Annual Meeting were mailed or delivered to the
shareholders of the Company on or about September 11, 1996.
 
MATTERS TO BE CONSIDERED
 
  At the Annual Meeting, you will be asked (i) to consider and vote to approve
the Share Purchase Agreement dated as of July 17, 1996, as amended (the "Share
Purchase Agreement"), entered into among PMT, Electrotech Limited ("ET"),
Electrotech Equipments Limited ("ETE," and collectively with ET,
"Electrotech"), Christopher D. Dobson and the other shareholders of
Electrotech and all transactions contemplated thereby (collectively, the
"Acquisition"), pursuant to which PMT will acquire 100% of the outstanding
capital stock of Electrotech and, directly or indirectly, each subsidiary
thereof for an aggregate of $75,000,000 (reduced by certain amounts to be
otherwise paid by PMT pursuant to the Share Purchase Agreement) and 5,600,000
shares of PMT common stock ("Common Stock"); (ii) to elect six directors of
PMT to serve during the ensuing year and until their successors are duly
elected and qualified; (iii) to consider and vote to approve the amendment of
PMT's 1991 Stock Option Plan to increase the number of shares of Common Stock
which may be issued thereunder from 900,000 to 1,300,000 (and to 2,400,000 if
the Acquisition occurs); (iv) to consider and vote to ratify the appointment
of Ernst & Young LLP ("Ernst & Young") as PMT's independent auditors for the
fiscal year ending December 31, 1996; and (v) to act upon such other business
as may properly come before the Annual Meeting, or any adjournment or
postponement thereof.
 
RECORD DATE AND VOTING
 
  The directors have fixed the close of business on September 9, 1996 as the
record date (the "Record Date") for the determination of shareholders entitled
to vote at the Annual Meeting and any adjournment or postponement thereof.
Only holders of record of Common Stock on the Record Date are entitled to
notice of and to vote at the Annual Meeting and any adjournment or
postponement thereof. As of the Record Date, there were outstanding 8,692,132
shares of Common Stock.
 
QUORUM AND VOTING MATTERS
 
  The holders of record of a majority of the combined voting power of the
outstanding shares of Common Stock present in person or represented by proxy
will constitute a quorum for the transaction of business at the Annual
Meeting. As to all matters except the election of directors, each shareholder
is entitled to one vote for each share of Common Stock held. Each holder of
Common Stock voting in the election of directors may, upon request, cumulate
such holder's votes and give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of shares of Common
Stock held by such holder, or distribute such holder's votes on the same
principle among as many candidates as the holder may select, provided that
votes
<PAGE>
 
cannot be cast for more than six candidates. However, no shareholder shall be
entitled to cumulate votes for any candidate unless, pursuant to the Bylaws of
the Company, the candidate's name has been placed in nomination prior to the
voting and the shareholder has given notice at the meeting prior to the vote
for directors of the shareholder's intention to cumulate such shareholder's
votes.
 
  All properly executed proxies that are not revoked will be voted at the
Annual Meeting in accordance with the instructions contained therein. Subject
to the "Broker Non-Vote" restrictions discussed below, proxies containing no
instructions regarding the proposals specified in the form of proxy will be
voted for approval of each of the matters scheduled to be considered at the
Annual Meeting as well as in accordance with the recommendation of PMT's Board
of Directors on all other matters. Any shareholder signing a proxy has the
power to revoke it prior to the Annual Meeting or at the Annual Meeting prior
to the vote pursuant to the proxy. A proxy may be revoked by delivering a
written notice of revocation or a duly executed proxy bearing a later date or
by attending the Annual Meeting and voting in person.
 
VOTE REQUIRED
 
  Approval of each of "Proposal No. 1--The Acquisition" and "Proposal No. 3--
Amendment of PMT's 1991 Stock Option Plan" requires the affirmative vote of
the holders of a majority of the outstanding shares of Common Stock entitled
to vote thereon. As a consequence, abstentions will have the effect of a
negative vote. See "Proposal No. 1--The Acquisition" and "Proposal No. 3--
Amendment of PMT's 1991 Stock Option Plan." With respect to the election of
directors, the six nominees who receive the greatest number of votes cast for
the election of those directorships shall become directors at the conclusion
of the tabulation of the votes. See "Proposal No. 2--Election of Directors."
 
SOLICITATION OF PROXIES AND EXPENSES
 
  PMT will bear the cost of the solicitation of proxies from its shareholders.
In addition to solicitation by mail, the directors, officers and employees of
PMT may solicit proxies from shareholders by telephone, telegram, letter or in
person. Arrangements will also be made with brokerage houses and other
custodians, nominees and fiduciaries for the forwarding of solicitation
material to the beneficial owners of stock held of record by such
shareholders, and PMT will reimburse such custodians, nominees and fiduciaries
for reasonable out-of-pocket expenses incurred by them in connection
therewith. PMT has not presently engaged any third party to assist in the
solicitation of proxies and to distribute materials to brokerage houses,
banks, custodians and other nominee holders. If PMT engages the services of a
third party proxy solicitor with respect to the matters set forth in this
Proxy Statement, all costs and expenses thereof will be paid for by PMT.
 
EFFECT OF BROKER NON-VOTES
 
  "Broker Non-Votes" occur when a broker holding shares of Common Stock in
street name withholds its vote on certain "non-routine" matters because the
broker has not received instructions from the beneficial owner of those shares
and does not have discretionary authority to vote on such non-routine matters
without specific instructions. Brokers holding shares in street name must
receive specific instructions from the beneficial owners in order to have the
authority to vote, in person or by proxy, on certain "non-routine" matters.
When a beneficial owner does not give specific instructions to the broker, the
broker, as the holder of record, is entitled to vote only on "routine" matters
and must withhold its votes as to any non-routine matters. Where a proxy
solicitation includes a non-routine proposal and the broker does not receive
specific instructions from the beneficial owner, the resulting proxy is
considered a "limited proxy." Shares represented by limited proxies are
considered present for quorum purposes, but are not considered present for
purposes of determining the total number of shares with voting power present
with regard to a non-routine proposal. The resulting Broker Non-Vote of such a
limited proxy will not be counted for or against such non-routine proposal.
 
  "Proposal No. 1--The Acquisition" and "Proposal No. 3--Amendment of PMT's
1991 Stock Option Plan" are non-routine proposals. Approval of each of
Proposal No. 1 and Proposal No. 3 requires the affirmative vote of a majority
of the outstanding shares of Common Stock entitled to vote thereon. The effect
of a limited
 
                                       2
<PAGE>
 
proxy will be that Broker Non-Votes will be treated as votes against Proposal
No. 1 and Proposal No. 3. "Proposal No. 2--Election of Directors" is a
"routine" matter upon which brokers can cast votes with or without specific
instructions from the beneficial holders and are thus counted for purposes of
determining whether Proposal No. 2 has been approved.
 
  The Common Stock is listed for trading on the Nasdaq National Market
("Nasdaq"). On September 9, 1996, the closing price for a share of Common
Stock on Nasdaq was $11.625.
 
  The principal executive offices of PMT are located at 9255 Deering Avenue,
Chatsworth, California 91311, and its telephone number is (818) 886-8000.
 
  The information set forth in this Proxy Statement concerning Electrotech has
been furnished by Electrotech.

Record Date; Quorum; Vote
 Required; Dissenters'
 Rights...................  The record date for determining the shareholders of
                            PMT entitled to vote upon the matters set forth in
                            this Proxy Statement is September 9, 1996 (the
                            "Record Date").
 
                            The presence, either in person or by properly des-
                            ignated proxy, at the Annual Meeting of the holders
                            of a majority of the outstanding shares of Common
                            Stock entitled to vote at such Meeting is necessary
                            to constitute a quorum.
 
                            Under Section 1201 of the California Corporations
                            Code, the Acquisition requires the affirmative vote
                            of the holders of a majority of the outstanding
                            shares of Common Stock entitled to vote thereon.
                            Additionally, due to the number of shares of Common
                            Stock to be issued to the Electrotech Shareholders
                            by PMT in the Acquisition, shareholder approval is
                            required pursuant to Rule 4460(i)(1)(C)(ii), prom-
                            ulgated pursuant to Article VII of the By-laws of
                            the National Association of Securities Dealers,
                            Inc. (the "NASD").
 
                            Pursuant to Chapter 13 of the California
                            Corporations Code, holders of Common Stock
                            generally will be entitled to obtain an appraisal
                            of the fair value of their respective shares only
                            if demands for payment are filed with respect to 5%
                            or more of the outstanding shares of Common Stock.
                            Holders of shares subject to certain transfer
                            restrictions may obtain such appraisal without
                            regard to such 5% requirement. It is a condition to
                            the consummation of the Acquisition that holders of
                            less than 5% of the outstanding shares of Common
                            Stock have perfected dissenters' rights. See
                            "Dissenting Shareholders' Right of Appraisal."
 
                            As of September 9, 1996 the directors and officers
                            of PMT beneficially owned 2,246,012 outstanding
                            shares of Common Stock (representing approximately
                            25.1% of the outstanding shares of Common Stock).
                            All such directors and officers intend to vote in
                            favor of the Acquisition.
 
                            ET and ETE are private, closely held corporations.
                            The execution of the Share Purchase Agreement
                            served as the approval of the Acquisition by the
                            Electrotech Shareholders and no other formal meet-
                            ing of the Electrotech Shareholders will be held.

THE ACQUISITION
 
Risks of the Acquisition..  The Acquisition involves certain risks, including
                            without limitation, those risks associated with the
                            cyclicality of the semiconductor industry
                            (including the current industry downturn), the
                            development and acceptance of new products and
                            systems, the rapid pace of technological change,
                            the effect of many business factors on quarterly
                            operating results, the highly competitive nature of
                            the semiconductor equipment industry, the
                            combination of PMT and Electrotech, lengthy sales
                            cycles for PMT's and Electrotech's products, the
                            importance of key personnel to PMT and Electrotech,
                            the increase in international exposure, the
                            importance of intellectual property rights to PMT
                            and Electrotech, future capital needs,
                            environmental regulations, customer concentration,
                            dilution in the ownership of PMT, shares available
                            for resale and volatile stock prices. For a
                            complete discussion of the risk factors relating to
                            the matters described in this Proxy Statement, see
                            "Risk Factors."

                            and ETE, together with a United States subsidiary
                            of ETE, will become a direct, wholly-owned subsidi-
                            ary of PMT. All other subsidiaries of ET and ETE
                            will become indirect wholly-owned subsidiaries of
                            PMT.
 
Effective Date of the       The Acquisition will be effective on the date upon
Acquisition...............  which the closing contemplated by the Share Pur-
                            chase Agreement occurs (the "Closing Date"). The
                            Closing Date is currently expected to be on or
                            about Friday, October 11, 1996, and is subject to
                            the satisfaction or waiver of the conditions prece-
                            dent to the Acquisition set forth in the Share Pur-
                            chase Agreement. See "Proposal No. 1--The Acquisi-
                            tion--Terms of the Acquisition and Related Transac-

                            Conditions to the Acquisition."
 
Terms of the Acquisition..  PMT will acquire all of the Electrotech Shares
                            outstanding for an aggregate of $75,000,000 in cash
                            (reduced by certain amounts to be otherwise paid by
                            PMT pursuant to the Share Purchase Agreement) and
                            5,600,000 shares of Common Stock, which shares will
                            be newly issued at such time. For further
                            discussion of the various reductions from the cash
                            portion of the purchase price for the Electrotech
                            Shares, see "Proposal No. 1--The Acquisition--Terms
                            of the Acquisition and Related Transactions--
                            Purchase Price," and "--Certain Payments at
                            Closing."
 
                            Based upon the Common Stock outstanding as of the
                            Record Date, and assuming that no outstanding PMT
                            warrants or stock options are exercised prior to
                            the Acquisition, 14,292,132 shares of Common Stock
                            will be outstanding upon consummation of the Acqui-
                            sition, of which 5,600,000 shares (approximately
                            39.2% of the total number of shares of Common Stock
                            outstanding) will be held in the aggregate by the
                            Electrotech Shareholders and of which 4,853,334

Terms of the Private
 Financing; Working
 Capital..................  As a condition to the consummation of the Acquisi-  
                            tion, the Share Purchase Agreement contemplates     
                            that, among other things, PMT will have issued and  
                            sold at least $50,000,000 in convertible subordi-   
                            nated notes (the "Convertible Notes") to qualified  
                            institutional buyers (the "Private Financing") pur- 
                            suant to Rule 144A under the Securities Act of      
                            1933, as amended (the "Securities Act"), or to      
                            other available applicable exemptions under the Se- 
                            curities Act. See "Proposal No. 1--The Acquisi-     
                            tion--Terms of the Acquisition and Related Transac- 
                            tions--Conditions to the Acquisition." PMT antici-  
                            pates that it will issue and sell approximately     
                            $65,000,000 in principal amount of Convertible      
                            Notes in the Private Financing, and that the Con-   
                            vertible Notes will be on terms and subject to con- 
                            ditions to be negotiated between PMT and the pur-   
                            chasers thereof. The initial purchasers of the Con- 
                            vertible Notes will be granted an over-allotment    
                            option with respect to an additional $9,750,000 in  
                            principal amount of Convertible Notes, which option 
                            will be exercisable by such initial purchasers      
                            within 30 days of the date of issuance of the Con-  
                            vertible Notes. PMT believes that the amounts       
                            raised in the Private Financing plus other sources  
                            of capital available to PMT will be sufficient to   
                            pay the cash portion of the purchase price for the  
                            Electrotech Shares and to satisfy the condition in  
                            the Share Purchase Agreement requiring that the     
                            cash and cash equivalents and assets, plus amounts  
                            then immediately available for additional           
                            borrowings under credit agreements of PMT and       
                            Electrotech at the Closing, on a consolidated pro   
                            forma basis after giving effect to the Acquisition, 
                            will not be less than $35,000,000 (the "Working     
                            Capital Condition"). See "Proposal No. 1--The Ac-   
                            quisition--Certain Other Items Related to the Ac-   
                            quisition--Terms of the Private Financing; Working  
                            Capital."
 
Restrictions on Transfer    
of Shares.................  The shares of Common Stock issued in the Acquisi-  
                            tion will be subject to restrictions on transfera- 
                            bility. In that regard, 746,666 of such shares of  
                            Common Stock may be sold in the public securities  
                            markets on and after the date that is 40 days from 
                            the Closing Date, pursuant to Regulation S of the  
                            Securities Act of 1933, as amended (the "Securities
                            Act"). Subject to certain volume restrictions im-  
                            posed by Rule 144 under the Securities Act, after  
                            such date, Mr. Dobson will also be permitted to    
                            sell a certain number of the 4,853,334 shares of   
                            Common Stock to be issued to him in the Acquisi-   
                            tion. In connection with the Private Financing, the
                            Electrotech Shareholders have agreed not to sell   
                            any of the shares of Common Stock received by them 
                            in the Acquisition for 90 days from the Closing    
                            Date. Additionally, on and after the first anniver-
                            sary of the Closing Date, Mr. Dobson has the right 
                            to request the registration of such shares of Com- 
                            mon Stock and also has the right to participate in 
                            any other registration statement filed by PMT after
                            such date. See "Proposal No. 1--The Acquisition--  
                            Terms of the Acquisition and Related Transactions--
                            Related Agreements."

                            CONTEMPLATED THEREBY ARE IN THE BEST INTEREST OF
                            PMT AND ITS SHAREHOLDERS AND RECOMMENDS THAT
                            SHAREHOLDERS VOTE IN FAVOR OF PROPOSAL NO. 1. For a
                            discussion of the reasons considered by PMT's Board
                            of Directors in approving the Share Purchase
                            Agreement, the Acquisition and all related
                            transactions, see "Proposal No. 1--The

                            Acquisition."
 
Opinion of Financial        
 Advisor..................  Salomon Brothers Inc ("Salomon Brothers") has been
                            retained by the PMT Board of Directors to act as
                            its financial advisor in connection with the Acqui-
                            sition. Salomon Brothers has delivered to the PMT
                            Board of Directors its written opinion, dated July
                            5, 1996, to the effect that, as of such date and
                            based upon and subject to the matters described
                            therein, the proposed Acquisition is fair to PMT
                            and its shareholders from a financial point of
                            view. Reference is made to the full text of such
                            opinion, a copy of which is set forth in Annex B in
                            its entirety. PMT shareholders are urged to read
                            this opinion carefully for a description of the
                            procedures followed, the factors considered and the
                            assumptions made by Salomon Brothers. See "Proposal
                            No. 1--The Acquisition--General Information--Opin-
                            ion of Financial Advisor."

                            fulfilled or waived, permit termination of the
                            Share Purchase Agreement. See "Proposal No. 1--The
                            Acquisition--Terms of the Acquisition and Related

                            consent of the parties. Except under certain cir-
                            cumstances, upon a termination of the Share Pur-
                            chase Agreement, PMT is required to pay a fee of
                            $1,000,000 to Electrotech and to reimburse certain
                            costs and expenses incurred by Electrotech. See

                            consummation of the Acquisition, although it is a  
                            condition to the obligations of the Electrotech    
                            Shareholders to consummate the Acquisition that the
                            Electrotech Shareholders have obtained tax         
                            clearance from certain U.K. taxing authorities. See

                            the Acquisition."

                            ers' rights. See "Dissenting Shareholders' Rights  
                            of Appraisal."

(1) The unaudited pro forma combined balance sheet data assumes the Acquisition
    and related financing of the Acquisition, through the issuance of
    $65,000,000 of Convertible Notes, took place on June 30, 1996, and combines
    PMT's June 30, 1996 balance sheet data with Electrotech's June 30, 1996
    balance sheet data using the purchase method of accounting. The unaudited
    pro forma statements of operations data assumes that the Acquisition and
    related financing took place as of the beginning of each of the periods
    presented using the allocation of the purchase information calculated as of
    June 30, 1996, and combines the statement of operations data for PMT and
    the profit and loss accounts data for Electrotech for the twelve month
    period ended December 31, 1995 and for the six month period ended June 30,
    1996. See "Pro Forma Financial Information." The underlying financial data
    of Electrotech used to develop the pro forma combined financial data has
    been converted to U.S. dollars using a conversion rate of $1.53 U.S. to
    (Pounds)1 sterling at June 30, 1996 and $1.55 U.S. to (Pounds)1 sterling at
    December 31, 1995, and to US GAAP for purposes of comparison.
(2) For purposes of computing the ratio of earnings to fixed charges,
    "earnings" consist of income from operations before income taxes plus fixed
    charges, and "fixed charges" consist of total interest expense plus an
    allocation of a portion of rent expense representing interest. Such ratio
    assumes the issuance of a principal amount of $65 million of Convertible
    Notes with an interest rate of 7.5%. Assuming that the initial purchasers'
    over-allotment is exercised and an aggregate of $74,750,000 in principal
    amount of Convertible Notes is issued, the ratio of earnings to fixed
    charges would be 1.44 and 3.00 for the twelve month period ended December
    31, 1995 and the six month period ended June 30, 1996, respectively.

as a result of certain factors, including those set forth below.
 
                                 RISK FACTORS
 
  The following factors should be considered carefully in evaluating the
proposal to approve the Acquisition. In general, these factors are discussed
separately with respect to PMT and Electrotech to the extent deemed
appropriate to reflect certain differences in their respective businesses. At
the same time, all discussions of the semiconductor and semiconductor
equipment industries, and factors affecting semiconductor equipment
manufacturers generally, should be considered applicable to both PMT and
Electrotech, unless the context otherwise requires. Furthermore, for periods
following the Acquisition, references to the products, business, results of
operations, financial condition or other factors affecting the combined
operations of PMT and Electrotech should be considered to refer to PMT and
Electrotech jointly (assuming the consummation of the Acquisition), unless the
context otherwise requires.
 
CYCLICALITY OF SEMICONDUCTOR INDUSTRY
 
  The semiconductor industry is highly cyclical and has historically
experienced periodic downturns, which have been characterized by diminished
product demand and production overcapacity. The semiconductor industry is
currently experiencing a downturn, which could have a severe adverse effect on
the semiconductor industry's demand for semiconductor processing equipment. In
certain instances, industry downturns have lasted for extended periods of
time. Each of PMT's and Electrotech's operations have been and will continue
to be dependent on the current and anticipated market demand for integrated
circuits (ICs) and products utilizing ICs that are produced by semiconductor
manufacturers. The current weakness in demand in the semiconductor industry,
and any continuation of this weakness in the future, is likely to materially
and adversely affect each of PMT's and Electrotech's business and results of
operations. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations of PMT--Recent Developments."
 
DEVELOPMENT AND ACCEPTANCE OF NEW PRODUCTS AND SYSTEMS
 
  PMT's MORI(TM) source offers an alternative etch environment for the
manufacture of ICs to the reactive ion etch (RIE), inductively coupled plasma
(ICP) and electron cyclotron resonance (ECR) etch technology currently used by
PMT's competitors.
 
  While Electrotech sells several proven products, Electrotech's Sigma
Forcefill(TM) system incorporates an alternative technology to conventional
physical vapor deposition (PVD) techniques by using low resistance aluminum
forced by high pressure argon to fill small diameter deep holes and vias on
ICs. Electrotech's competitors produce systems that use a conventional
chemical vapor deposition (CVD) tungsten system to fill deep holes and vias.
Electrotech's Planar 200 Flowfill(TM) system uses a CVD technique applied to
silicon dioxide
 
                                      14
<PAGE>
 
that allows for gap filling and planarization. Competing products include spin
on glass (SOG) and high density plasma (HDP) coupled with a chemical
mechanical polishing (CMP) process.
 
  PMT has sold a limited number of its PINNACLE 8000(R) and PINNACLE 8000R(TM)
etch systems to a small number of customers. Electrotech's Sigma Forcefill(TM)
and Planar 200 Flowfill(TM) are currently at the stage of customer review and
evaluation; however, considerable efforts are being applied by Electrotech to
attain product functionality and reliability levels acceptable to
Electrotech's target markets. To date, the substantial majority of PMT's sales
of its etch systems and all of Electrotech's sales of Sigma Forcefill(TM) and
Planar 200 Flowfill(TM) systems have been initial purchases by customers of
individual systems. Typically, semiconductor manufacturers initially purchase
individual systems and deploy them in a development or pre-production
environment prior to purchasing multiple systems for production. There can be
no assurance that any of such customers will purchase additional systems from
either PMT or Electrotech for deployment in production.
 
  Given that certain of PMT's and Electrotech's systems represent an
alternative to conventional etch, PVD and CVD systems currently marketed by
competitors, management believes that continued growth depends in large part
upon the ability of PMT and Electrotech to gain acceptance of their systems
and technology. Due to the substantial investment required by semiconductor
manufacturers to install and integrate capital equipment into a semiconductor
production line, these manufacturers will tend to choose equipment
manufacturers based on past relationships, product compatibility and proven
financial performance. Once a semiconductor manufacturer has selected a
particular vendor, management believes that the manufacturer generally relies
upon the equipment supplied by that vendor for the specific production line
application, and frequently will attempt to consolidate its other capital
equipment requirements with the same vendor. As a result, semiconductor
manufacturers will normally engage in a long period of analysis and planning
before determining to convert to a new vendor of capital equipment. Given
these factors, there can be no assurance that either PMT or Electrotech will
be successful in obtaining broader acceptance of its new systems or of PMT's
MORI(TM) source or Electrotech's Forcefill(TM) or Flowfill(TM) technologies.
 
RAPID TECHNOLOGICAL CHANGE
 
  The markets in which PMT and Electrotech and their customers compete are
characterized by rapidly changing technology, the introduction of alternative
technologies, evolving industry standards and continuous improvements in
products and services. Management believes that its future success will
depend, in part, upon its ability to continue to improve PMT's and
Electrotech's systems and process technologies and to develop new technologies
and systems which compete effectively on the basis of total cost of ownership
and performance and which adequately address customer requirements.
 
QUARTERLY OPERATING RESULTS AFFECTED BY MANY BUSINESS FACTORS
 
  PMT has routinely experienced fluctuations in quarterly results and
currently derives most of its quarterly revenue from the sale of a small
number of etch systems which typically have list prices ranging from
approximately $975,000 to $3,100,000. During PMT's last five fiscal quarters,
PMT shipped virtually all of its systems in the last week of such quarters.
Accordingly, the timing of the shipment of a single PMT system could have a
significant impact on PMT's recognition of revenue and its quarterly operating
results. Historically, PMT's backlog at the beginning of a quarter has not
included all sales required to achieve its sales objectives for that quarter.
As of August 31, 1996, backlog was approximately $4.0 million for PMT, as
compared to $8.7 million at December 31, 1995. Substantially all of the orders
constituting backlog of PMT as of August 31, 1996 will be shipped during PMT's
fiscal quarter ending September 30, 1996. PMT's quarterly product sales and
operating results have historically depended on the receipt of orders and the
shipment of products in that same quarter.
 
  Electrotech also derives a significant percentage of its quarterly revenues
from the shipment of a relatively small number of systems varying in price
from approximately $600,000 to $4,000,000. Product sales and operating results
for a particular quarter could be adversely affected if an anticipated order
for even one PMT or Electrotech system is not received in time to permit
shipment during that quarter. A delay in a shipment near the end of a
particular quarter may cause product sales in that quarter to fall below
expectations, and may thus
 
                                      15
<PAGE>
 
materially and adversely affect operating results for such quarter, which will
have an adverse impact on the market price of the Common Stock. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations of PMT--Recent Developments."
 
  As a result of their continued investments in research, development and
engineering, and the development of a worldwide sales and marketing
organization, PMT and Electrotech have significant fixed costs that they will
not be able to reduce rapidly if their sales goals for a particular period are
not met. The impact of this factor on operating results in any future period
cannot be forecasted accurately.
 
HIGHLY COMPETITIVE INDUSTRY
 
  The markets served by PMT's and Electrotech's products are extremely
competitive. Following the Acquisition, PMT and Electrotech will each face
significant competition from various suppliers of systems that utilize
alternative technologies. In the etch market, PMT's MORI(TM)-based etch
systems and Electrotech's etch products face competition from suppliers of RIE
systems, including Applied Materials, Lam Research and Tokyo Electron, from
ICP-based etch systems marketed by Applied Materials and Lam Research, as well
as the ECR-based etch system marketed by Hitachi. Additionally, in the etch
market, PMT and Electrotech compete with each other. In the PVD market,
Electrotech's Forcefill(TM) technology faces competition from suppliers of
aluminum PVD systems, such as Applied Materials, Tokyo Electron, MRC, Varian
and Ulvac. In the CVD market, Electrotech's Flowfill(TM) technology faces
competition from a number of CVD competitors, including Applied Materials, Lam
Research, Novellus and Watkins-Johnson.
 
  Many of these competitors are substantially larger companies with broader
product lines, and have well established reputations in the markets in which
PMT and Electrotech compete, longer operating histories, greater experience
with high volume manufacturing, broader name recognition, substantially larger
customer bases and substantially greater financial, technical and marketing
resources than either PMT or Electrotech. Both PMT and Electrotech also face
potential competition from new entrants in their respective markets, including
established manufacturers in other segments of the semiconductor capital
equipment market, who may decide to diversify into the market segments of PMT
or Electrotech. There can be no assurance that their competitors will not
develop enhancements to or future generations of competitive products that
will offer price and performance features superior to those offered by PMT's
or Electrotech's systems.
 
COMBINATION OF PMT AND ELECTROTECH
 
  The combination of PMT and Electrotech following the Acquisition will result
in a significant increase in the number of employees to be employed by PMT and
will bring new operating facilities to PMT, most of which are located in the
United Kingdom and Europe. While management currently intends to maintain the
corporate identities and operations of PMT and Electrotech, seeking only to
consolidate their worldwide sales organizations, the combination of PMT and
Electrotech may strain available managerial, financial and other resources.
There can be no assurance that the combination of PMT and Electrotech will be
successfully managed or will not result in significant unforeseen operating
expenses.
 
LENGTHY SALES CYCLE
 
  Sales of each of PMT's and Electrotech's systems typically involve a lengthy
period during which each may expend substantial funds and management effort.
Such sales will depend, in significant part, upon the decision of a
prospective customer to increase manufacturing capacity or to expand current
manufacturing capacity, both of which involve a significant capital commitment
by the customer. The amount of time from initial contact with a customer to
the first order is typically nine to twelve months, and may be longer, and may
involve competing capital budget considerations for the customer, thus making
the timing of customers' orders uneven and difficult to predict. PMT's and
Electrotech's ability to receive orders for production systems from potential
semiconductor manufacturing customers depends, among other things, upon such
customers undertaking an evaluation for new equipment. Presently, all of the
Sigma Forcefill(TM) and the Planar 200 Flowfill(TM) systems sold are being
used by such customers to evaluate the future manufacturing capabilities of
 
                                      16
<PAGE>
 
such systems. There can be no assurance that Electrotech will receive any
further orders for Sigma Forcefill(TM)or Planar 200 Flowfill(TM) systems from
any of the customers who have purchased such systems for evaluation purposes.
Similarly, the majority of PMT's Pinnacle 8000(R) and Pinnacle 8000R(TM)
systems sold to date have been sold as single systems. Prior to placing orders
for production systems, semiconductor manufacturing customers expect to
evaluate systems on an extended trial basis. Following initial system
qualification, both PMT and Electrotech often experience further delays in
finalizing system sales while the customer evaluates and receives approvals
for the purchase of its systems and completes a new or expanded facility. The
failure or inability of each of PMT and Electrotech to convert an evaluation
system with a customer to a sale of production systems could materially and
adversely affect operations.
 
FAILURE TO RETAIN KEY PERSONNEL
 
  Each of PMT and Electrotech is dependent upon the efforts and abilities of a
number of its current key personnel. Following the Acquisition, Dr. Gregor
Campbell, James Marshall and Harvey Frye, currently the President and Chief
Executive Officer, Executive Vice President and Chief Operating Officer and
Vice President, Sales and Marketing, respectively, of PMT, will serve as PMT's
Chief Executive Officer, Executive Vice President, Operations and General
Manager, Etch and Vice President, Worldwide Sales and Marketing, respectively.
Christopher Dobson and Nigel Wheeler, currently Chairman of the Board and
Chief Executive Officer, respectively, of Electrotech will, following the
Acquisition, serve as PMT's Vice Chairman of the Board and President and Chief
Operating Officer, respectively. Following the Acquisition, management
believes that PMT's success will, to a significant degree, depend upon its
ability to retain these and other key employees of PMT and Electrotech. The
loss of certain of these people or PMT's inability to retain other key
employees could materially and adversely affect operations after the
Acquisition.
 
INCREASED INTERNATIONAL EXPOSURE
 
  International sales accounted for approximately 76%, 47%, 66%, and 50% of
PMT's total revenue for the six months ended June 30, 1996, the year ended
December 31, 1995, the ten months ended December 31, 1994, and the year ended
February 1994, respectively. Similarly, Electrotech sales outside of the
United States accounted for approximately 84%, 82%, 72% and 74% of
Electrotech's total revenue for the fiscal years ended June 30, 1996, 1995,
1994 and 1993, respectively. Management anticipates that, following the
Acquisition, sales outside of the United States will account for a majority of
total revenue. International sales are subject to certain risks, including
unexpected changes in regulatory requirements, exchange rates, tariffs and
other barriers, political and economic instability, difficulties in accounts
receivable collections, extended payment terms, the challenges of maintaining
a readily available supply of spare parts, difficulties in managing
distributors or representatives, difficulties in staffing and managing foreign
subsidiary operations, and potentially adverse tax consequences. In addition,
international sales may be materially adversely affected by currency risks
associated with devaluation of certain currencies. There can be no assurance
that these and other factors will not have a material adverse effect on
revenue.
 
INTELLECTUAL PROPERTY RIGHTS
 
  Both PMT and Electrotech rely on a variety of types of intellectual property
protection to protect proprietary technology, including patent, copyright,
trademark and trade secret laws, non-disclosure agreements and other
intellectual property protection methods. Although management believes that
PMT's and Electrotech's patents and trademarks may have value, management
believes that its future success will also depend on the innovation, technical
expertise and marketing abilities of its personnel. PMT currently holds a
number of patents in the United States and has patent applications pending in
South Korea, Japan and Europe.
 
  Electrotech currently holds a number of patents in the United Kingdom, the
United States, Taiwan, Germany, France, Italy and the Netherlands and is
currently in the process of defending a challenge to the validity of its
European ICP patent. There can be no assurance as to the resolution of this
patent dispute and an
 
                                      17
<PAGE>
 
unfavorable result could materially and adversely affect Electrotech.
Electrotech also has a number of patent applications pending worldwide,
including applications for its Forcefill(TM) technology.
 
  There can be no assurance that patents will be issued on PMT's or
Electrotech's pending patent applications or that competitors will not be able
to legitimately ascertain proprietary information embedded in their products
which is not covered by patent or copyright. In such case, PMT or Electrotech
may be precluded from preventing the competitor from making use of such
information. In addition, should either PMT or Electrotech wish to assert its
patent rights against a particular competitor's product, there can be no
assurance that any claim in a PMT or Electrotech patent, as the case may be,
will be sufficiently broad nor, if sufficiently broad, any assurance that the
PMT or Electrotech patent will not be challenged, invalidated or circumvented,
or that PMT or Electrotech will have sufficient resources to prosecute their
respective rights. Each of PMT and Electrotech has a policy to protect and
defend vigorously its patents, trademarks and trade secrets.
 
  There are no pending lawsuits against either PMT or Electrotech regarding
infringement of any existing patents or other intellectual property rights or,
except as described above, any unresolved claim where either PMT or
Electrotech has received notice that it is infringing the intellectual
property rights of others. There can be no assurance, however, that such
infringement claims will not be asserted in the future nor can there be any
assurance, if such claims were made, that PMT or Electrotech would be able to
defend against such claims successfully or, if necessary, obtain licenses on
reasonable terms. In addition, management believes that litigation in the
semiconductor equipment industry over patent and other intellectual property
rights has been increasing in recent years.
 
  Any involvement in a patent or other intellectual property dispute or in any
action to protect trade secrets and know-how, even if successful, could
materially and adversely affect operations. Adverse determinations in any such
action could subject each of PMT or Electrotech to significant liabilities,
require it to seek licenses from third parties, which might not be available,
and possibly prevent it from manufacturing and selling its products, any of
which could materially and adversely affect operations.
 
FUTURE CAPITAL NEEDS
 
  Both PMT and Electrotech are capital intensive companies that require
significant funds to conduct operations and require regular and significant
investments in inventory and working capital. In order to remain competitive
following the Acquisition, PMT and Electrotech must continue to make
significant investments in technology and systems, in the expansion of their
operations, in evaluation systems and in research and development. As a
condition to the consummation of the Acquisition, the cash and cash equivalent
assets plus amounts immediately available for additional borrowings under
credit agreements of PMT and Electrotech at the Closing, on a consolidated pro
forma basis immediately after giving effect to the Acquisition, will not be
less than $35,000,000. Additionally, as a condition to its consummation of the
Acquisition, PMT must offer and sell at least $50,000,000 in convertible
subordinated notes (the "Convertible Notes"). The incurrence of such debt will
increase PMT's leverage position and may make it more difficult to raise
additional funds in the future. While management believes that such financial
resources should be sufficient for PMT's and Electrotech's capital needs in
the next 12 months, there can be no assurance in that regard.
 
ENVIRONMENTAL REGULATIONS
 
  PMT is subject to a variety of federal, state and local laws, rules and
regulations in the United States relating to the use, storage, discharge and
disposal of hazardous chemicals used during its customer demonstrations and in
research and development activities. Public attention has increasingly been
focused on the environmental impact of operations which use hazardous
materials. In 1995, the United Kingdom adopted a new and comprehensive
environmental law known as the Environmental Act of 1995 (the "Environmental
Act"), which, among other things, deals with the allocation of responsibility
for the cleanup of contaminated property and expands potential liability with
respect to the remediation of such contamination. Electrotech owns or leases a
number of facilities in the United Kingdom, and compliance with the
Environmental Act is anticipated to result
 
                                      18
<PAGE>
 
in certain expenses which are not expected to be material. However, there can
be no assurance that such expenses will not exceed present estimates. Failure
to comply with present or future regulations could result in substantial
liability to PMT or Electrotech, suspension or cessation of their operations,
restrictions on their ability to expand at their present locations, or
requirements for the acquisition of significant equipment or the incurrence
other significant expense.
 
CUSTOMER CONCENTRATION
 
  To date Electrotech's sales have been highly concentrated, with
approximately 28% of its revenue for the year ended June 30, 1996 derived from
sales to Siemens. There can be no assurance that Siemens will continue to
purchase machinery and technology from Electrotech at current levels, or at
all. To date PMT has experienced some concentration of customers and, in
future periods, the concentration of PMT's customers could increase.
 
DILUTION OF OWNERSHIP OF PMT; SIGNIFICANT INFLUENCE OF MR. DOBSON
 
  Following the Acquisition, the former shareholders of Electrotech will
beneficially own approximately 39% of the Common Stock outstanding. Mr. Dobson
will own approximately 34% of the Common Stock outstanding and will be the
Vice Chairman of the Board of Directors of the Company. Mr. Dobson will be in
a position to have a significant influence on the election of directors and
other corporate matters that require the vote of PMT shareholders.
Additionally, the Convertible Notes will be convertible into shares of Common
Stock; the exact number of shares will be based on market conditions at the
time of issuance. Assuming that $65,000,000 in Convertible Notes are issued,
under current market conditions such Convertible Notes would be convertible
into approximately 4,500,000 shares of Common Stock. The issuance of such
shares of Common Stock and the conversion of the Convertible Notes will
represent substantial dilution of the ownership interest in PMT by its current
shareholders.
 
SHARES AVAILABLE FOR RESALE
 
  As a result of the Acquisition, PMT will issue 5,600,000 additional shares
of Common Stock, of which 746,666 shares may be sold in the public securities
markets on and after the date that is 40 days from the closing of the
Acquisition, pursuant to Regulation S of the Securities Act of 1933, as
amended (the "Securities Act"). Subject to certain volume restrictions imposed
by Rule 144 under the Securities Act, after such date Mr. Dobson will also be
permitted to sell a certain number of the 4,853,334 shares of Common Stock
issued to him in the Acquisition. Future sales of a substantial amount of
Common Stock in the public market could adversely affect the market price of
the Common Stock. In connection with the Private Financing, the Electrotech
Shareholders have agreed not to sell any of the shares of Common Stock
received by them in the Acquisition for 90 days from the Closing Date.
 
  Approximately 3,108,421 shares of Common Stock held by certain significant
shareholders of PMT, including 1,638,354 shares held by PMT affiliates, are
presently available for resale in the public market, subject to certain
restrictions on volume imposed by Rule 144 under the Securities Act.
 
VOLATILE STOCK PRICE
 
  Since PMT's initial public offering in late August 1995, the market price
for the Common Stock has been highly volatile. Following the Acquisition,
management believes that a variety of factors could cause the price of the
Common Stock to continue to fluctuate, perhaps substantially, including:
announcements of developments related to PMT's or Electrotech's business;
fluctuations in operating results and order levels; general conditions in the
semiconductor industry or the worldwide economy; announcements of
technological innovations; new products or product enhancements by PMT or
Electrotech or by their competitors; developments in patents or other
intellectual property rights; and developments in PMT's and Electrotech's
relationships with its employees, customers, distributors and suppliers. In
addition, in recent years the stock market in general, and the market for
shares of the stock of technology-based issuers in particular, has experienced
extreme price fluctuations which have often been unrelated to the operating
performance of affected companies. Such fluctuations could adversely affect
the market price of the Common Stock.

                        PROPOSAL NO. 1--THE ACQUISITION
 
                              GENERAL INFORMATION
 
BACKGROUND OF THE ACQUISITION
 
  In December 1995 and January 1996, representatives of PMT, including Dr.
Gregor Campbell, PMT's President and Chief Executive Officer, and John
Rollwagen, PMT's Chairman of the Board, met at various times in Japan, the
United Kingdom and Los Angeles with representatives of Electrotech, including
Christopher Dobson, Chairman of the Board, and Nigel Wheeler, President and
Chief Executive Officer, of Electrotech to explore the possibility of a
business combination between PMT and Electrotech. To allow for the free flow
of information relating to the parties, PMT and Electrotech entered into a
confidentiality agreement on December 19, 1995.
 
  To assist in PMT's evaluation of a possible acquisition of Electrotech, in
January 1996 PMT engaged Salomon Brothers Inc ("Salomon Brothers") to act as
its financial advisor. Similarly, to assist Electrotech in evaluating the
terms of any acquisition offer, in January 1996 Electrotech engaged Hambrecht
& Quist as its financial advisor.
 
  In February and March 1996, representatives of PMT initiated PMT's due
diligence investigation of Electrotech, and various meetings between the
principal executive officers of each of PMT and Electrotech were convened.
 
  On March 14, 1996, a meeting of the shareholders of Electrotech was held in
Bristol, England to discuss the possible acquisition of Electrotech by PMT. At
this meeting, the Electrotech shareholders agreed on an allocation among
themselves of the cash and stock portions of the proposed consideration for
Electrotech and authorized certain cash payments to Electrotech employees,
including the payments to be made to Mr. Dobson at the closing of any such
transaction, bonuses to Electrotech employees and a bonus to Mr. Wheeler.
 
  At the regularly scheduled meetings of PMT Board of Directors held on
January 17, 1996 and April 24, 1996, the potential acquisition of Electrotech
was presented to Board members by senior management of PMT and by
representatives of Salomon Brothers. At these meetings, the Board reviewed
certain financial and valuation information relating to Electrotech that it
deemed relevant, and authorized management to continue to investigate the
possible acquisition of Electrotech and to analyze various financial
alternatives to provide financing for any such acquisition, including a
commercial credit facility and PMT's private placement of debt and equity.
 
  During May and June 1996, PMT executives, along with PMT's legal, accounting
and financial advisors, traveled to Wales in the United Kingdom to conduct and
conclude PMT's due diligence investigation of Electrotech. In May 1996,
Electrotech's accountants traveled to Los Angeles to conduct various due
diligence inquiries with respect to PMT operations.
 
  In late June 1996, PMT management and its financial and legal advisors met
with the management of Electrotech and its financial and legal advisors to
negotiate the terms and conditions of a definitive acquisition agreement.
 
  On July 5, 1996, a special telephonic meeting of the PMT Board of Directors
was held to update the Board with respect to remaining open issues relating to
the Acquisition. During this meeting Salomon Brothers presented a financial
analysis of Electrotech and orally presented its opinion that the acquisition
consideration to be paid to Electrotech shareholders was fair to the
shareholders of PMT, from a financial point of view. The Board approved the
terms and conditions of the Share Purchase Agreement and authorized the
transactions contemplated thereby, including without limitation, the
Acquisition, pending resolution by PMT management of all remaining open
business issues.
 
                                      20
<PAGE>
 
  During the week of July 8, 1996 and the week of July 15, 1996, executives of
PMT and Electrotech spoke and met to resolve all open business issues and to
conclude the negotiation of the Share Purchase Agreement. On July 17, 1996,
the Directors of each of ET and ETE unanimously approved the Share Purchase
Agreement and the transactions contemplated thereby. On July 17, 1996,
executives of PMT and Electrotech met in San Francisco to execute the
definitive Share Purchase Agreement to enable PMT to acquire Electrotech for
5,600,000 shares of Common Stock and $75 million in cash (reduced by certain
amounts to be otherwise paid by PMT pursuant to the Share Purchase Agreement).
 
RATIONALE FOR THE ACQUISITION
 
  PMT's Board of Directors has unanimously approved the Share Purchase
Agreement, has determined that the Acquisition and all other transactions
contemplated thereby are in the best interest of PMT and its shareholders and
recommends that shareholders vote in favor of Proposal No. 1. In reaching
these conclusions, the PMT Board of Directors considered a number of factors
that PMT shareholders should be cognizant of in deciding whether to vote in
favor of Proposal No. 1, including the following:
 
  Access to Complementary Leading Edge Technologies. By acquiring Electrotech,
PMT believes that it will gain access to two new leading edge deposition
technologies for use by semiconductor manufacturers, Electrotech's
Forcefill(TM) and Flowfill(TM) technologies. The combination of PMT's
MORI(TM)-based products with Electrotech's Sigma Forcefill(TM) sputtering PVD
system and Planar 200 Flowfill(TM) system will give PMT proprietary
technologies in its three targeted segments of the semiconductor fabrication
industry--etch, CVD and PVD.
 
  Leverage Marketing, Sales, Support and Service Resources. Semiconductor
manufacturers are increasingly demanding local service and support from their
equipment suppliers, and the ability to offer such worldwide service and
support requires significant investment in infrastructure, including the
establishment and maintenance of support facilities throughout the world. By
acquiring Electrotech, PMT will both increase its worldwide presence and make
its resources available to its customers at, what management believes, will be
a favorable cost to PMT. Following the Acquisition, PMT will have access to a
substantially larger marketing, sales, support and service force throughout
the world, to jointly support each of PMT's and Electrotech's products and
customers.
 
  Complementary Strengths in Geographic Distribution. While PMT already has a
sales and distribution network in the United States and a growing sales and
distribution network in Asia, Electrotech has a limited sales and distribution
presence in the United States and Asia, with its primary strength in Europe, a
region in which PMT has little presence. Sales and distribution channels for
PMT and Electrotech should be significantly improved, with each gaining access
to major markets currently served by the other.
 
  Ability to Cross Sell to Expanded Customer Base. Many of the products
offered by PMT and Electrotech are complementary or targeted at different
applications within the semiconductor manufacturing market. The Acquisition
will afford to each of PMT and Electrotech the opportunity to sell their
products into an expanded customer base.
 
  Critical Mass. Following the Acquisition, management expects that the size
and breadth of PMT's and Electrotech's product offerings will produce a
stronger and more competitive company in the semiconductor equipment
marketplace, a marketplace dominated by significant companies such as Applied
Materials and Lam Research.
 
OPINION OF FINANCIAL ADVISOR
 
  At the meeting of the PMT Board on July 5, 1996, at which the PMT Board
approved the Share Purchase Agreement and the transactions contemplated
thereby, Salomon Brothers delivered its opinion to the effect that, as of such
date, the consideration to be paid by PMT in connection with the proposed
Acquisition is fair to the
 
                                      21
<PAGE>
 
shareholders of PMT from a financial point of view. No limitations were
imposed by PMT with respect to the investigations made or the procedures
followed by Salomon Brothers in rendering its opinion.
 
  THE FULL TEXT OF THE OPINION OF SALOMON BROTHERS DATED JULY 5, 1996, WHICH
SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW
UNDERTAKEN, IS ATTACHED AS ANNEX B TO THIS PROXY STATEMENT. PMT SHAREHOLDERS
ARE URGED TO READ SUCH OPINION IN ITS ENTIRETY. SALOMON BROTHERS' OPINION IS
DIRECTED ONLY TO THE FAIRNESS OF THE CONSIDERATION TO BE PAID BY PMT AND DOES
NOT CONSTITUTE A RECOMMENDATION TO ANY PMT SHAREHOLDER AS TO HOW SUCH
SHAREHOLDER SHOULD VOTE WITH RESPECT TO THE ACQUISITION. THE SUMMARY OF THE
OPINION OF SALOMON BROTHERS SET FORTH IN THIS PROXY STATEMENT IS QUALIFIED IN
ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
  In arriving at its opinion, Salomon Brothers reviewed the Share Purchase
Agreement and its related exhibits. Salomon Brothers also reviewed certain
publicly available business and financial information relating to PMT, as well
as certain other information, including financial projections, provided to
Salomon Brothers by PMT and Electrotech. Salomon Brothers discussed the past
and current operations and financial condition and prospects of PMT and
Electrotech with members of senior management of PMT and Electrotech,
respectively. Salomon Brothers also considered such other information,
analyses, investigations and financial, economic, market and trading criteria
that it deemed relevant.
 
  In arriving at its opinion, Salomon Brothers assumed and relied on the
accuracy and completeness of the information reviewed by it for the purpose of
its opinion, and did not assume any responsibility for independent
verification of such information or for any independent evaluation or
appraisal of the assets of PMT or Electrotech. With respect to PMT's and
Electrotech's financial projections, Salomon Brothers assumed that such
projections had been reasonably prepared on bases reflecting the best
currently available estimates and judgments of the management of PMT or
Electrotech, as the case may be, as to the future financial performance of PMT
or Electrotech, as the case may be, and expressed no opinion with respect to
such forecasts or the assumptions on which they were based.  Salomon Brothers
also assumed that the Acquisition would be accounted for as a purchase in
accordance with generally accepted accounting principles.  Salomon Brothers'
opinion was necessarily based upon business, market, economic and other
conditions as they existed on, and could be evaluated as of, the date of its
opinion and did not address PMT's underlying business decision to effect the
Acquisition, nor did it constitute a recommendation to any holder of Common
Stock as to how such holder should vote with respect to the Acquisition.
Salomon Brothers' opinion did not imply any conclusion as to the likely
trading range for Common Stock following the consummation of the Acquisition,
which may vary depending on, among other factors, changes in interest rates,
dividend rates, market conditions, general economic conditions and other
factors that generally influence the price of securities.
 
  In arriving at its opinion and making its presentation to the PMT Board at
the July 5, 1996 meeting, Salomon Brothers considered and discussed certain
financial analyses and other factors. As part of its evaluation of
Electrotech, Salomon Brothers performed the following: (a) a public market
valuation, which analyzes a company's operating performance and outlook
relative to a group of publicly-traded peers to determine an implied
unaffected market trading value (in performing this analysis, Salomon Brothers
selected companies that it deemed comparable to Electrotech's most significant
business segments, comparing certain financial information of Electrotech to
that of other such companies); and (b) a discounted cash flow analysis, which
provides insight into the intrinsic value of a company based on projected
earnings and capital requirements. As part of its evaluation of the
consideration to be paid by PMT in connection with the Acquisition, Salomon
Brothers also performed the following: (i) a pro forma merger analysis, in
which Salomon Brothers analyzed certain pro forma effects on PMT resulting
from the Acquisition; and (ii) a contribution analysis, in which Salomon
Brothers compared the relative ownership of the stockholders of PMT and the
stockholders of Electrotech in the surviving corporation to the projected
contributions attributable to equity of each of PMT and Electrotech.
 
                                      22
<PAGE>
 
  This summary is not a complete description of the analyses performed by
Salomon Brothers. In addition, Salomon Brothers believes that its analyses
must be considered as a whole and that selecting portions of such analyses and
of the factors considered by it, without considering all of such analyses and
factors, could create an incomplete view of the process underlying the
analyses set forth in the opinion and the presentation. The preparation of a
fairness opinion is a complex process and is not necessarily susceptible to
partial analysis or summary description. With regard to the public market
valuation analysis referred to above, Salomon Brothers selected comparable
public companies on the basis of various factors, including the size of the
public company and similarity of the line of business; however, no public
company utilized as a comparison is identical to Electrotech or the business
segments for which a comparison was made. Accordingly, an analysis of the
foregoing is not mathematical; rather, it involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the comparable companies and other factors that could affect the acquisition
or public trading value of the comparable companies to which Electrotech or
its business segments are being compared. In performing its analyses, Salomon
Brothers made numerous assumptions with respect to industry performance,
general business and economic conditions and other matters, many of which are
beyond PMT's or Electrotech's control. Any estimates contained in such
analyses are not necessarily indicative of actual past or future results or
values, which may be significantly more or less than such estimates. Estimates
of values of companies or parts of companies do not purport to be appraisals
or necessarily to reflect the price at which such companies or parts may
actually be sold, and such estimates are inherently subject to uncertainty.
 
  Salomon Brothers is an internationally recognized investment banking firm
that regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions. The PMT Board selected Salomon
Brothers to act as its financial advisor on the basis of Salomon Brothers'
international reputation, PMT's prior relationship with Salomon Brothers and
Salomon Brothers' familiarity with PMT. Salomon Brothers is familiar with PMT,
having provided certain investment banking and financial advisory services to
it from time to time, including acting as managing underwriter with respect to
PMT's initial public offering in August 1995 and participating in certain of
the negotiations leading to the Share Purchase Agreement.
 
  Salomon Brothers has acted as financial advisor to PMT in connection with
the Acquisition and will receive a fee for its services, a portion of which
was paid upon engagement, a portion of which became payable upon the initial
filing of this Proxy Statement and the remaining portion of which is payable
upon the consummation of the Acquisition. Salomon Brothers will also act as
placement agent with respect to PMT's proposed offering of Convertible Notes.
In the ordinary course of Salomon Brothers' business, Salomon Brothers and its
affiliates may actively trade the equity securities of PMT for its own account
and for the accounts of customers and, accordingly, may at any time hold a
long or short position in such securities.
 
MANAGEMENT AFTER THE ACQUISITION
 
 Directors
 
  PMT's current directors will continue to serve as directors following the
Acquisition. Additionally, pursuant to the Share Purchase Agreement and
assuming that the Acquisition is approved by PMT's shareholders and is
consummated in accordance with the terms of the Share Purchase Agreement, the
Board of Directors will be expanded from six to eight and Mr. Dobson and Mr.
Wheeler will be appointed to fill such newly-created vacancies. All such
directors will serve until their successors have been duly elected and
qualified or otherwise as provided by law. See "Proposal No. 2--Election of
Directors."
 
 Officers
 
  Following the consummation of the Acquisition, Dr. Campbell will relinquish
his position as President of PMT but will continue to serve as Chief Executive
Officer of PMT and Mr. Marshall will relinquish his role as Chief Operating
Officer of PMT and will assume the role of Executive Vice President,
Operations and General Manager, Etch. Mr. Dobson will become Vice Chairman of
PMT's Board of Directors and Mr. Wheeler will assume the role of President and
Chief Operating Officer of PMT. All other executive officers of PMT are
expected to remain in their present positions following the Acquisition.
 
  See "Management--Management of PMT," and "--Management of Electrotech."

               TERMS OF THE ACQUISITION AND RELATED TRANSACTIONS
 
  The detailed terms of, and conditions to, the Acquisition and certain related
transactions are contained in the Share Purchase Agreement and its exhibits, as
amended, a copy of which (including such exhibits) is attached to this Proxy
Statement as Annex A and incorporated herein by reference. The statements made
in this Proxy Statement with respect to the terms of the Acquisition and such
related transactions are qualified in their entirety by reference to the more
complete information set forth in Annex A.
 
STRUCTURE OF THE ACQUISITION
 
  The Share Purchase Agreement provides that PMT will acquire from the
Electrotech Shareholders all of the outstanding capital stock of Electrotech
and, to accommodate certain tax planning objectives, will first directly
acquire from ETE all of the outstanding stock of a United States subsidiary.
The transactions will be consummated at a closing (the "Closing") to be held
following the satisfaction or waiver of certain conditions precedent specified
in the Share Purchase Agreement. See "--Conditions to the Acquisition" below.
The Acquisition will be consummated in two steps on the date of the Closing
(the "Closing Date"), as follows: (a) immediately prior to the Closing, PMT
will acquire from ETE all of the outstanding shares of ETE's United States
subsidiary, Energy Transfer Systems, Inc., a Delaware corporation ("ETS"); and
(b) upon the Closing, PMT will acquire from each of the Electrotech
Shareholders all of the outstanding shares of Electrotech held thereby. By
acquiring such shares of Electrotech, PMT will thus indirectly acquire
ownership of all other Electrotech subsidiaries.
 
PURCHASE PRICE
 
  The consideration to be paid by PMT for the shares of ETS and Electrotech
will be as follows: (a) PMT will pay to ETE the sum of $250,000 as full
consideration for the shares of ETS being acquired directly from ETE; and (b)
PMT will pay to the Electrotech Shareholders, as the cash portion of the
purchase price for all of the outstanding shares of Electrotech, the aggregate
sum of $75,000,000 (reduced by the amounts described in the following
paragraph), payable in cash at the Closing to each of the Electrotech
Shareholders in the respective individual amounts set forth opposite each such
Electrotech Shareholder's name on Exhibit A to the Share Purchase Agreement,
and PMT will additionally issue an aggregate of 5,600,000 shares of Common
Stock to the Electrotech Shareholders in the respective amounts set forth
opposite each Electrotech Shareholder's name on Exhibit A to the Share Purchase
Agreement.
 
  The $75,000,000 cash portion of the purchase price for Electrotech shares
will be reduced, pro rata with respect to the amounts to be received by each of
the Electrotech Shareholders, by the following amounts: (a) the cash sum of
$500,000 to be paid to Mr. Dobson by PMT at the Closing pursuant to the
Noncompetition Agreement in the form attached as Exhibit E to the Share
Purchase Agreement (the "Noncompetition Agreement"); (b) the cash sum of
approximately $1,500,000, the precise amount of which shall be specified by Mr.
Dobson prior to the Closing as the amount which, when added to the $250,000
cash amount to be paid by PMT to ETE for the shares of ETS as described above,
represents the U.S. dollar equivalent of one British pound
 
                                       25
<PAGE>
 
sterling for each day that all employees of Electrotech and their subsidiaries
as of the Closing shall have been continuously employed by them as of the
Closing (such amount will be paid to Electrotech by PMT at the Closing as a
contribution to capital, for the subsequent payment of such amount by
Electrotech to the described employees as a bonus for past services); (c) a
cash sum, the precise amount of which shall be specified by Mr. Dobson prior
to the Closing, calculated to result in an after-tax payment (assuming the
highest marginal income tax rates) to Mr. Wheeler of approximately $600,000,
as a bonus for past services rendered (such amount will be paid to Electrotech
by PMT at the Closing as a contribution to capital, for subsequent payment to
Mr. Wheeler); and (d) the cash sum of $7,000,000, to be paid to Mr. Dobson by
Electrotech at the Closing (the "Dobson Negotiation Fee"), which amount will
first be paid to Electrotech by PMT at the Closing as a contribution to
capital. See "--Certain Payments at Closing" below.
 
  It is anticipated that, after deducting the amounts described in the
preceding paragraph, the cash portion of the purchase price payable to the
Electrotech Shareholders will be reduced to approximately $65,000,000. Of this
approximate amount, $35,000,000 will be paid to Mr. Dobson and his wife, and
$15,000,000 each will be paid to the remaining two shareholder groups. Of the
5,600,000 shares of Common Stock to be issued, 4,853,334 shares (or 87% of the
total) will be issued to Mr. Dobson and his wife, and the balance will be
issued equally (373,333 shares each) to the other two shareholder groups. See
Exhibit A to the Share Purchase Agreement.
 
EFFECTIVENESS OF THE ACQUISITION
 
  The Acquisition will become effective as soon as practicable, but no later
than five days following the satisfaction or waiver of all of the conditions
to the Acquisition specified in the Share Purchase Agreement, or at such other
time as PMT and the Electrotech Shareholders shall agree after the
satisfaction or waiver of such conditions. See "--Conditions to the
Acquisition" below. It is anticipated that, if the Acquisition is approved by
PMT's shareholders at the Annual Meeting and all other conditions to the
Acquisition (including but not limited to the consummation of the Private
Financing, described below under "--Conditions to the Acquisition") have been
fulfilled or waived, the Closing of the Acquisition will occur as soon as
practicable following the approval of the Acquisition by the shareholders of
PMT.

and conditions); (g) all necessary waivers, consents and approvals to or of
the transactions contemplated by the Share Purchase Agreement of any third

  The foregoing summary of the various representations and warranties of the
parties is qualified in its entirety by the full text of the representations
and warranties of the Electrotech Shareholders, Mr. Dobson and PMT set forth
in Articles III, IV and V, respectively, of the Share Purchase Agreement
attached to this Proxy Statement as Annex A.
 
LIMITED SURVIVAL OF REPRESENTATIONS AND WARRANTIES
 
  Although the accuracy of the representations and warranties of each party
(considering Electrotech and the Electrotech Shareholders collectively as a
single party for this purpose) is a condition to the obligation of the other
to consummate the Acquisition (See "--Conditions to the Acquisition" above),
the Share Purchase Agreement provides that except solely with respect to the
Surviving Shareholder Warranties and the Surviving PMT Warranties (as
described below), all representations and warranties contained in the Share
Purchase Agreement shall terminate and be extinguished upon, and shall not
survive, the Closing. Accordingly, following the Closing no party shall have
any recourse against the other for breach of any representation or warranty,
except only with respect to the Shareholder Surviving Warranties and the
Surviving PMT Warranties.
 
  The Shareholder Surviving Warranties, which shall survive the Closing for
the applicable statute of limitations period, are those of each Electrotech
Shareholder contained in Article III of the Share Purchase Agreement (with
respect to ownership of and title to Electrotech shares, and the power and
authority to transfer the same to PMT), and with respect solely to Mr. Dobson,
those set forth in Sections 4.3 (authorized, issued and outstanding capital
stock of Electrotech, and ownership of and title thereto), 4.4 (power and
authority of the Electrotech Shareholders to consummate the Acquisition) and
6.4(b) (accuracy of all information provided by Electrotech and the
Electrotech Shareholders for inclusion in this Proxy Statement).
 
  The Surviving PMT Warranties, which also shall survive the Closing for the
applicable statute of limitations, consist of those set forth in Section 5.3
(authorized, issued and outstanding capital stock of PMT), 5.4 (Common Stock
to be issued in the Acquisition), 5.5 (power and authority of PMT to
consummate the Acquisition) and 6.4(b) (accuracy of all information provided
by PMT for inclusion in this Proxy Statement).
 
                                      29

INDEMNIFICATION
 
  PMT has agreed, upon and subject to the consummation of the Acquisition, to
indemnify Electrotech and the Electrotech Shareholders in respect of any
claims, obligations, costs and expenses which they may incur arising out of
the material breach of any of the Surviving PMT Warranties (as described above
under "--Limited Survival of Representations and Warranties"). Similarly, each
Electrotech Shareholder has agreed to indemnify and hold harmless PMT from and
against any and all claims, obligations, costs and expenses arising out of the
material breach of any of the Surviving Shareholder Warranties (as also
described above under "--Limited Survival of Representations and Warranties"),
though the indemnification of each Electrotech Shareholder other than Mr.
Dobson is limited to such shareholder's ownership of, title to and ability to
transfer its Electrotech shares being purchased by PMT at the Closing.

  Under the terms of the Share Purchase Agreement, and for the period from the
July 17, 1996 date of the Share Purchase Agreement and continuing until its
termination or the Closing of the Acquisition, each member of Electrotech and

ADDITIONAL COVENANTS OF THE PARTIES
 
  Each member of Electrotech, on the one hand, and PMT, on the other hand, has
further agreed to afford the other with reasonable access prior to the Closing
to all of such party's properties, books, accounts, agreements, personnel,
facilities, proprietary information, contracts, commitments and records,
including without limitation, in the case of Electrotech, permitting PMT's

at the owned and leased real properties of Electrotech and its subsidiaries.
Each party has further undertaken to use its reasonable efforts to take or
cause to be taken all action, and to do or cause to be done all things
necessary, proper or advisable to consummate the transactions contemplated by
the Share Purchase Agreement, including the obtaining of all necessary
waivers, consents and approvals of all third parties and governmental
authorities necessary for the consummation of the Acquisition. Each such party
has also agreed to deliver to the other, until the Closing: (a) as soon as
practicable, but no later than 30 days after the end of each month (extended

its fiscal year), an unaudited consolidated profit and loss account or

  Each Electrotech Shareholder has further agreed that it will not, directly
or indirectly, transfer, sell, assign, pledge, hypothecate, encumber or
otherwise dispose of any of Electrotech shares which such shareholder owned at

purposes, provided that such trusts become a party to and otherwise bound by
the Share Purchase Agreement). Additionally, each member of Electrotech and
each Electrotech Shareholder has agreed that it will not, nor shall any of
Electrotech's directors, officers, other employees or other representatives or
agents, directly or indirectly communicate, solicit, initiate, encourage or

Proposal"). Each member of Electrotech and each Electrotech Shareholder has

not offer, sell or contract to sell, or otherwise dispose of, directly or
indirectly, or commence an offering of, any shares of Buyer's Common Stock
beneficially owned by such Shareholder or any securities convertible into, or
exchangeable for, shares of Buyer's Common Stock for a period of 90 days
following the Closing Date, without the prior written consent of Salomon
Brothers.
 
  PMT agreed to prepare and file with the Commission, and mail to its
shareholders, this Proxy Statement with respect to the Annual Meeting of PMT
shareholders to consider and vote, among other things, upon the Acquisition
and the transactions contemplated thereby. Each member of Electrotech and each
Electrotech Shareholder agreed to assist and cooperate with PMT in the
preparation of this Proxy Statement with respect to information herein
concerning them.
 
CERTAIN PAYMENTS AT CLOSING
 
  PMT has agreed in the Share Purchase Agreement that, upon the Closing of the
Acquisition, PMT will pay to Mr. Dobson the cash amount of $500,000 pursuant
to the Noncompetition Agreement (see "--Related Agreements" below) and deliver
to Electrotech the following aggregate amounts and property as contributions
to capital: (a) at the discretion of the Board of Directors of ET and ETE, the
cash sum of approximately $1,500,000, the precise amount of which shall be
specified by Mr. Dobson prior to the Closing as the amount which, when added
to the $250,000 to be paid by PMT for the ETS shares, represents the U.S.
dollar equivalent of one pound sterling for each day that all employees of
Electrotech and its subsidiaries as of the Closing have been continuously
employed by them as of the Closing (the "Employee Bonus"); (b) a cash sum, the
precise amount of which shall be specified by Mr. Dobson prior to the Closing,
calculated to result in an after-tax bonus payment (assuming the highest
marginal income tax rates) to Mr. Wheeler of approximately $600,000 (the
"Wheeler Bonus"); and (c) the cash sum of $7,000,000, to be paid to Mr. Dobson
as a negotiation fee (the "Dobson Negotiation Fee"). The Electrotech companies
have accordingly agreed to pay or deliver (or cause their subsidiaries to pay
or deliver) on or after the Closing (i) the Employee Bonus, to their employees
entitled thereto, (ii) the Wheeler Bonus to Mr. Wheeler for past services
rendered, and (iii) the Dobson Negotiation Fee to Mr. Dobson.
 
  PMT has furthermore agreed that, at and following the Closing, it will cause
Electrotech and its subsidiaries to honor in accordance with their terms all
existing employment arrangements with their respective directors, officers and
other employees, provided that such arrangements have been disclosed in
accordance with the terms of the Share Purchase Agreement. Furthermore, PMT
has represented and warranted that it presently intends to cause Electrotech
and its subsidiaries to continue indefinitely to provide pension and welfare
benefits to their employees (considered as a group) which benefits are
intended to be in the aggregate no less favorable than those currently
provided by Electrotech and its subsidiaries in the aggregate to such
employees. PMT has further agreed that, sufficiently prior to the Closing to
facilitate the grant of such stock options, PMT will recommend to its Board of
Directors and Compensation Committee thereof the grant, under its 1991 Stock
Option Plan, of options covering an aggregate of approximately 800,000 shares
of Common Stock to such employees of Electrotech and its subsidiaries, and in
such respective individual amounts, as shall be jointly determined by PMT and
Mr. Dobson prior to the Closing. Such option grants are otherwise to be at
prices and upon terms as are customarily contained in options generally
granted under PMT's 1991 Stock Option Plan.
 
  PMT has also agreed that it will not file with the Commission any disclosure
document, any document related to the Private Financing or any report or other
document filed by PMT under the Exchange Act or otherwise made public, that
includes the names of any of Electrotech, the Electrotech Shareholders or any
affiliate of such persons, without the prior written consent of Mr. Dobson,
except solely as and to the extent that PMT is advised by its legal counsel
that the same is required to be so filed (in which case Mr. Dobson shall be
given reasonable opportunity to review and reasonably modify any such proposed
filing).

PRE-CLOSING ELECTROTECH DIVIDENDS
 
  Although Electrotech is prohibited from paying or distributing any amounts
as dividends or otherwise to any of the Electrotech Shareholders, the Share
Purchase Agreement specifically provides that Electrotech may, prior to the
Closing, declare and pay cash dividends to the Electrotech Shareholders up to
an amount permitted by law but not exceeding the net cash payment specified in
Section 1.4(a) of the Share Purchase Agreement (being the $75,000,000 amount
described above under "--Purchase Price," after the deductions described
therein), in which case the parties have agreed that (a) PMT shall,
immediately prior to the Closing, loan to Electrotech an amount equal to the
sum of such dividends, plus all taxes required to be paid by Electrotech in
connection with the payment of such dividends (the "Dividend Taxes"), in order
to fund the payment of such dividends immediately prior to the Closing and the
payment of the Dividend Taxes; (b) the cash portion of the purchase price for
Electrotech shares otherwise payable to the Electrotech Shareholders at the
Closing shall be reduced, pro rata as to each Electrotech Shareholder, by an
aggregate amount equal to such loan by PMT; (c) immediately after the Closing,
the indebtedness of Electrotech to PMT in respect of such loan shall be
forgiven by PMT as a contribution to the capital of Electrotech (but subject
to the contingent obligation of Electrotech to make the payments described in
the following clause); and (d) from time to time if and when Electrotech is
entitled to a credit for the Dividend Taxes against other amounts due and
payable for income taxes of Electrotech, then Electrotech shall pay to the
Electrotech Shareholders (promptly after such time as Electrotech would have
otherwise been required to pay such income taxes), pro rata to each
Electrotech Shareholder in the same proportion that the cash portion of the
purchase price was reduced, the aggregate amount of such credit.
 
TERMINATION, AMENDMENT AND WAIVER
 
  The Share Purchase Agreement may be terminated at any time by the mutual
written consent of PMT and Mr. Dobson. The Share Purchase Agreement may also
be terminated by any party if the Closing of the Acquisition has not occurred
on or before December 31, 1996.
 
  The Share Purchase Agreement may be terminated by PMT alone if there is a
material breach of any of the representations and warranties of any member of
Electrotech or any Electrotech Shareholder, or if any member of Electrotech or
any Electrotech Shareholder fails to comply in any material respect with any
of its respective covenants or agreements contained in the Share Purchase
Agreement. Similarly, the Share Purchase Agreement may be terminated by the
Electrotech Shareholders alone if there is a material breach of any of such
representations and warranties of PMT, or if PMT fails to comply in any
material respect with any such covenants or agreements.
 
  The Share Purchase Agreement may be amended only by an instrument in writing
signed by each of the parties thereto. At any time prior to the Closing, any
party to the Share Purchase Agreement (considering Electrotech and Electrotech
Shareholders collectively as a single party for this purpose) may (a) extend
the time for performance of any obligation of the other party, (b) waive any
inaccuracies in the representations and warranties made to such party in the
Share Purchase Agreement or any document delivered in connection therewith and
(c) waive compliance with any of the agreements or conditions for the benefit
of such party contained in the Share Purchase Agreement.
 
TERMINATION FEE AND CERTAIN ACQUISITION EXPENSES
 
  Upon any termination of the Share Purchase Agreement (except solely a No-Fee
Termination, as described in the following paragraph), PMT must pay to
Electrotech an aggregate fee of $1,000,000 (the "Termination Fee"), and PMT
must additionally pay to Electrotech all reasonable fees and expenses actually
incurred by them in connection with the transactions contemplated by the Share
Purchase Agreement, including all reasonable legal, investment banking,
accounting and other fees and expenses (the "Reimbursable Expenses"). Upon the
execution of the Share Purchase Agreement and pursuant thereto, PMT advanced
to Electrotech an aggregate of approximately $624,000 in respect of all
Reimbursable Expenses then payable to third parties other than
 
                                      33
<PAGE>
 
Hambrecht & Quist, excluding any internal charges or expenses of Electrotech
or any of its subsidiaries. Such amount is considered an advance in respect of
any amounts which may ultimately be owed by PMT to Electrotech upon the
termination of the Share Purchase Agreement and, if no amounts are ever so
owed by reason of the occurrence of a No-Fee Termination of the Share Purchase
Agreement, Electrotech must, within seven days following the occurrence of
such No-Fee Termination, refund to PMT all amounts so advanced.
 
  A "No-Fee Termination" of the Share Purchase Agreement relieves PMT of its
obligation to pay the Termination Fee and Reimbursable Expenses to
Electrotech, and consists of the following: (a) any termination by PMT or the
Electrotech Shareholders if a governmental authority or other agency or
commission or court shall have enacted, issued, promulgated, enforced or
entered any statute, rule, regulation, injunction or other order which has the
effect of prohibiting the consummation of the transactions contemplated by the
Share Purchase Agreement (limited to United Kingdom matters in the case of a
termination by PMT, and limited to United States matters in the case of a
termination by the Electrotech Shareholders); (b) any termination by the
Electrotech Shareholders by reason of their failure to obtain the ET Tax
Clearance; (c) any termination by PMT by reason of the non-occurrence of any
of the conditions to PMT's obligation to consummate the Acquisition; provided,
however, that any termination by PMT as the result of any failure by PMT to
consummate the Private Financing, to obtain approval of the Share Purchase
Agreement by PMT's shareholders, or to complete additional environmental
investigations of Electrotech to PMT's satisfaction, and any termination by
PMT as the result of a material adverse change in the financial condition,
assets, liabilities, business, operations, results of operations or prospects
of Electrotech or as a result of the failure to meet the Dissenters' Rights
Condition, shall not constitute a No-Fee Termination and shall not relieve PMT
of its obligation to pay the Termination Fee and Reimbursable Expenses; and
(d) any termination by the Electrotech Shareholders as the result of a
material adverse change in the financial condition, assets, liabilities,
business, operations, results of operations or prospects of PMT.
 
  PMT will in any event be responsible for all of its own costs and expenses
incurred in connection with the Acquisition and the transactions contemplated
thereby, whether or not the Closing occurs.
 
EFFECT OF TERMINATION
 
  Except to the extent that PMT may be obligated to pay the Termination Fee
and Reimbursable Expenses (and except to the extent that Electrotech may
become obligated to repay the $624,000 advance made by PMT in respect of
Reimbursable Expenses), in the event of a termination of the Share Purchase
Agreement it shall become void and there will be no liability on the part of
any party thereto, provided that no party shall be relieved of any liability
for any intentional breach of the purchase and sale covenants contained in the
Share Purchase Agreement, or the covenant to use reasonable efforts to satisfy
all conditions to the Closing, which breach results in a termination of the
Share Purchase Agreement. Additionally, a covenant of each party to refrain
from publicly stating any disparaging or similar remark regarding the other
shall continue for a one-year period following any termination of the Share
Purchase Agreement.
 
RELATED AGREEMENTS
 
  Certain additional agreements to be executed at the Closing are attached as
Exhibits to the Share Purchase Agreement, consisting of: (a) the Employment
Agreement between PMT and Mr. Wheeler, the execution of which is a condition
to the obligations of the Electrotech Shareholders under the Share Purchase
Agreement; (b) the Registration Agreement between PMT and Mr. Dobson, the
execution of which is also a condition to the obligations of the Electrotech
Shareholders under the Share Purchase Agreement, and (c) the Noncompetition
Agreement between PMT and Mr. Dobson, the execution of which is a condition to
the obligation of PMT under the Share Purchase Agreement.
 
  Employment Agreement. The Employment Agreement provides that Mr. Wheeler
will be employed by PMT as its President and Chief Operating Officer for a
term of three years, which term will be automatically renewed for additional
one-year periods unless terminated by either party at least 30 days prior to
the commencement of the additional one-year period. The Employment Agreement
provides that Mr. Wheeler's base
 
                                      34
<PAGE>
 
salary will be $250,000 per year (which will be reviewed annually and may be
adjusted upward by PMT), and that Mr. Wheeler will be additionally eligible to
participate in such bonus programs and other benefit plans and arrangements as
are generally made available to executive officers of PMT. It also provides
for the grant to Mr. Wheeler of options to purchase 200,000 shares of Common
Stock under PMT's 1991 Stock Option Plan, at an exercise price equal to the
fair market value of the underlying shares of Common Stock on the date of
grant (which will be the Closing Date), which options will vest in four equal
annual installments on each anniversary of the date of grant. These options
are included in the options covering approximately 800,000 shares to be
granted by PMT at the Closing to certain employees of the members of
Electrotech and their subsidiaries as shall be jointly determined by PMT and
Mr. Dobson prior to the Closing. See "--Conditions to the Acquisition" above.
If Mr. Wheeler is terminated by PMT "for cause" or if he terminates his
employment "without good reason" (as those terms are defined in the Employment
Agreement), or if he dies during the term of the Employment Agreement, he will
be entitled only to receive his salary and other amounts actually accrued
through the date of termination. Upon any other termination, he will generally
be entitled to receive his base salary (at the rate in effect upon the date of
termination) through the remainder of the term of the Employment Agreement
(but not less than one year), without set-off or reduction, and will be
entitled to the vesting of his stock options and to receive generally all
other benefits to which he is entitled under the Employment Agreement through
the remainder of such term. The Employment Agreement also provides that while
Mr. Wheeler is employed and for such period after employment during which he
continues to receive payments at least equal to his base salary pursuant to
the Employment Agreement, he will not compete with PMT in any area in the
world where PMT's products or services are offered or sold.
 
  Registration Rights Agreement. The Registration Rights Agreement to be
entered into by PMT and Mr. Dobson provides that, with respect to 4,853,334
shares of Common Stock to be received by Mr. Dobson pursuant to the
Acquisition, Mr. Dobson may, on not more than three occasions at any time
commencing on the first anniversary of the Closing Date, require PMT at its
sole expense to prepare, file with the Commission and use its best efforts to
cause to be declared effective and maintained effective for up to 120 days, a
registration statement under the Securities Act covering the public offer and
sale of such shares. The Registration Rights Agreement also provides that,
commencing on and after the first anniversary of the Closing Date, Mr. Dobson
shall have customary "piggyback" registration rights in the event PMT proposes
to register any of its stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash. The
Registration Rights Agreement contains additional customary terms and
provisions, including reciprocal indemnification and contribution provisions
with respect to information furnished or provided by PMT or Mr. Dobson for
inclusion in any such registration statement.
 
  Noncompetition Agreement. The Noncompetition Agreement between PMT and Mr.
Dobson provides that, in consideration of the payment to Mr. Dobson by PMT of
$500,000 at the Closing and further in order to confirm in PMT the goodwill of
the business of Electrotech being acquired by PMT pursuant to the Acquisition,
Mr. Dobson shall not, for a period of three years commencing upon the Closing,
directly or indirectly carry on or participate in any business anywhere in the
world in competition with the business of Electrotech as the same exists
immediately prior to the Acquisition and as the same is to be carried on
following the Acquisition.
 
                CERTAIN OTHER ITEMS RELATED TO THE ACQUISITION
 
ACCOUNTING TREATMENT
 
  The Acquisition is to be treated as a purchase for accounting purposes.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The Acquisition will not have any U.S. federal, state or local income tax
effect on any PMT shareholder, unless such shareholder exercises dissenters'
rights. See "Dissenting Shareholders' Rights of Appraisal."
 
                                      35
<PAGE>
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
  PMT and Electrotech are not aware of any governmental or regulatory
approvals required for consummation of the Acquisition, although it is a
condition to the obligations of the Electrotech Shareholders to consummate the
Acquisition that the Electrotech Shareholders have obtained tax clearance from
certain U.K. taxing authorities.
 
TERMS OF THE PRIVATE FINANCING; WORKING CAPITAL
 
  As one of PMT's conditions to the consummation of the Acquisition, the
Private Financing requires PMT to issue and sell at least $50,000,000 in
convertible subordinated notes (the "Convertible Notes") to qualified
institutional buyers (the "Buyers") pursuant to Rule 144A of the Commission
(or other available applicable exemptions under the Securities Act). PMT
presently anticipates that it will issue approximately $65,000,000 in
principal amount of Convertible Notes in the Private Financing, and that the
Convertible Notes will be on terms and subject to conditions, including
without limitation, the right, first exercisable at some future date, to
convert such Convertible Notes into shares of Common Stock, as may be
negotiated between PMT and the Buyers. The initial purchasers of the
Convertible Notes will be granted an over-allotment option with respect to an
additional $9,750,000 in principal amount of Convertible Notes, which option
will be exercisable by such initial purchasers within 30 days of the date of
issuance of the Convertible Notes. Additionally, the obligation of PMT and the
Electrotech Shareholders to effect the Acquisition is subject, among other
things, to the condition that the cash and cash equivalent assets of PMT and
Electrotech at the Closing, plus amounts then immediately available to them
through additional borrowings under credit arrangements, on a consolidated pro
forma basis immediately after giving effect to the Acquisition, shall equal at
least $35,000,000 (the "Working Capital Condition"). PMT anticipates the
establishment of a new working capital line which will be consistent with the
requirements of the Working Capital Condition (the "Working Capital
Facility"), which facility will be effective as of the closing of the
Acquisition.
 
  Management of PMT believes that the cash provided or available from the
Convertible Notes and other sources of capital available to PMT, including
cash, cash equivalents and short-term investments presently on hand, will be
sufficient to pay the cash portion of the purchase price due under the Share
Purchase Agreement at the Closing and to pay for the costs and expenses of
PMT, including without limitation, the Reimbursable Expenses, resulting from
the Acquisition.
 
RESTRICTIONS ON TRANSFER OF SHARES
 
  The shares of Common Stock to be received by the Electrotech Shareholders on
the consummation of the Acquisition will be offered and sold in a manner
intended to comply with the conditions contained in Regulation S under the
Securities Act. In that regard, each Electrotech Shareholder has represented
and warranted to PMT, among other things, that (a) such shareholder is not a
"U.S. person" (as defined in Regulation S) and is not acquiring shares of
Common Stock for the benefit of any "U.S. person;" (b) during the period of 40
days following the Closing (the "Restricted Period"), such shareholders will
not engage in any activity for the purpose of, or what may be reasonably be
expected to have the effect of, conditioning the market in the United States
for the sale of any shares of Common Stock to be held by such shareholder, and
will not offer, sell, transfer, pledge or otherwise dispose of such shares in
the United States or to or for the account or benefit of a "U.S. person;" (c)
such shareholder 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) shares of Common Stock otherwise than
in compliance with the Securities Act, any applicable state securities or blue
sky laws and any applicable securities laws of jurisdictions outside the
United States, and the rules and regulations promulgated thereunder; and (d)
during the period commencing five business days before the Closing and
continuing through the Restricted Period, such shareholder will not directly
or indirectly, execute or effect or cause to be executed or effected any short
sale, option or equity swap transaction in or with respect to the Common Stock
or any other derivative security transaction, the purpose or effect of which
is to hedge or transfer to a third party all or any part of the risk of loss
associated with such shareholder's ownership of shares of Common Stock.
Additionally, the share certificates representing the shares of Common Stock
delivered to the Electrotech Shareholders will contain a restrictive legend
that will restrict the sale of such shares in accordance with the restrictions
of Regulation S during the Restricted Period.
 
                                      36
<PAGE>
 
  Following the Restricted Period, Electrotech Shareholders holding 746,666
shares of Common Stock will be permitted to sell such shares into the public
market without restriction. Subject to certain volume restrictions imposed
under Rule 144 under the Securities Act, after the Restricted Period Mr.
Dobson will also be permitted to sell a portion of the 4,853,334 shares of
Common Stock held by him into the public market. In connection with the
Private Financing, the Electrotech Shareholders have agreed not to sell any of
the shares of Common Stock received by them in the Acquisition for 90 days
from the Closing Date.
 
                 DISSENTING SHAREHOLDERS' RIGHTS OF APPRAISAL
 
  Pursuant to Chapter 13 of the California General Corporation Law ("Chapter
13"), a holder of shares of Common Stock may, in some instances, be entitled
to require PMT to purchase his or her shares for cash at their fair market
value as of the day before the first announcement of the terms of the
Acquisition ("Dissenting Shares"), excluding any appreciation or depreciation
in consequence of the Acquisition. Except as noted below, shares of Common
Stock will qualify as Dissenting Shares only if demands for payment are timely
filed and perfected with respect to 5% or more of the outstanding shares of
Common Stock. This 5% requirement is applicable because the Common Stock is on
the list of OTC margin stocks issued by the Board of Governors of the Federal
Reserve System. However, this 5% requirement does not apply to any shares
which the holder is legally unable freely to sell publicly because of transfer
restrictions imposed under securities laws and related agreements with PMT
("Restricted Shares").
 
  IT IS A CONDITION TO THE ACQUISITION THAT THE HOLDERS OF LESS THAN 5% OF THE
OUTSTANDING COMMON STOCK EXERCISE DISSENTING SHAREHOLDERS' RIGHTS OF
APPRAISAL.
 
  The general terms of the Acquisition were first announced on July 18, 1996.
The following is a brief summary of the procedures to be followed by a PMT
shareholder in order to perfect his or her right, if any, to payments under
Chapter 13 and is qualified in its entirety by reference to the text of
Chapter 13 attached to this Proxy Statement as Annex E, to which reference is
hereby made for a definitive statement of the rights of dissenting
shareholders (the "Dissenting Shareholders") and the procedures to be
followed.
 
  A Dissenting Shareholder who wishes to require PMT to purchase his or her
respective shares of Common Stock must:
 
    (1) vote against the Acquisition any or all of the shares of Common Stock
  entitled to be voted (shares of Common Stock not voted have the effect of
  being voted against the Acquisition but will not be counted toward the 5%
  minimum for dissenters' rights generally to exist); provided that if a PMT
  shareholder votes part of the shares entitled to be voted in favor of the
  Acquisition, and fails to specify the number of shares voted, it is
  conclusively presumed under California law that such shareholder's
  approving vote is with respect to all shares entitled to be voted;
 
    (2) make written demand upon PMT or its transfer agent at the addresses
  listed below, which is received not later than the date of the meeting of
  shareholders, setting forth the number of shares of Common Stock demanded
  to be purchased by PMT and a statement as to claimed fair market value of
  such shares at July 17, 1996; and
 
    (3) submit for endorsement, within 30 days after the date on which the
  notice of approval of the Acquisition by the shareholders described below
  is mailed to such shareholders, to PMT or its transfer agent at the
  addresses listed below, the certificates representing any shares in regard
  to which demand for purchase is being made, or to be exchanged for
  certificates of appropriate denominations so endorsed, with a statement
  that the shares are Dissenting Shares.
 
  The statement of fair market value in clause (2) above will constitute an
offer by the Dissenting Shareholder to sell his or her shares at a price equal
to such fair market value. Neither a vote against approval of the Acquisition
nor the giving of a proxy directing a negative vote will be sufficient to
constitute the demand
 
                                      37
<PAGE>
 
described in clause (2) above. A proxy which fails to include instructions
with respect to approval of the Acquisition will be voted in favor of the
Acquisition. Accordingly, the shares covered by such proxy will not be
Dissenting Shares. In addition, a vote in favor of the Acquisition, or a
failure to vote at all, will nullify any previously filed written demand for
payment.
 
  Within 10 days after the date of the approval of the Acquisition, PMT will
mail to each Dissenting Shareholder who holds Common Stock a notice of such
approval together with a statement of the price determined by PMT to represent
the fair market value of Dissenting Shares, a copy of certain sections of
Chapter 13, and a brief description of the procedure to be followed if the
shareholder desires to exercise his or her dissenters' rights. The statement
of price will constitute an offer by PMT to purchase at the price stated
therein any Dissenting Shares.
 
  If PMT and the Dissenting Shareholder agree that any shares of Common Stock
are Dissenting Shares and agree upon the price of the shares, the Dissenting
Shareholder will be entitled to the agreed price plus interest thereon at the
legal rate on judgments from the date of such agreement. Subject to the
provisions of the California General Corporation Law, payment of the fair
market value of the Dissenting Shares will be made within 30 days after such
agreement or within 30 days after any statutory or contractual conditions to
the Acquisition are satisfied, whichever is later. If PMT denies that the
shares are Dissenting Shares or if PMT and the Dissenting Shareholder fail to
agree upon the fair market value of the shares, then the Dissenting
Shareholder, within six months after the date on which notice of approval of
the Acquisition by the shareholders of PMT is mailed to such shareholder, and
not thereafter, may file a complaint in the Superior Court of Los Angeles
County, California, requiring the court to determine whether the shares are
Dissenting Shares, or the fair market value of the Dissenting Shares, or both,
or may intervene in any pending action for the appraisal of any shares of
Common Stock. The court will direct payment of the appraised value of the
shares, together with interest thereon at the legal rate on judgments from the
date on which the judgment was entered, by PMT to the shareholder upon the
surrender of the certificates representing such shares to PMT. The costs of
the proceeding shall be apportioned as the court considers equitable, but if
the appraisal exceeds the price offered by PMT, it shall pay the costs, and if
the appraisal is more than 125% of the price offered by it, it may be required
to pay attorneys' and other fees and interest at the legal rate on judgments
from the date the shareholder complied with Sections 1300-1302 of Chapter 13.
 
  A Dissenting Shareholder may not withdraw a demand for purchase of
Dissenting Shares without PMT's consent. Written demands for payment and
submissions for endorsement with respect to Common Stock must be addressed to
Plasma & Materials Technologies, Inc., 9255 Deering Avenue, Chatsworth,
California 91311, attention: John W. LaValle or to PMT's transfer agent,
American Stock Transfer & Trust Company, 40 Wall Street, New York, New York
10005.
 
  Any reference to "Dissenting Shareholder" in this section "Dissenting
Shareholders' Rights of Appraisal" means the recordholder of Dissenting Shares
of PMT and includes a transferee of record.
 
  Shareholders are entitled, upon written demand, to inspect and copy the
record of PMT shareholders at any time during usual business hours to
communicate with other PMT shareholders with respect to the Acquisition.
 
  A shareholder receiving cash upon the exercise of dissenters' rights may
recognize gain or loss for income tax purposes. Each such shareholder must
consult with his or her tax advisor in order to determine the income tax
effect of the exercise of such dissenters' rights by such shareholder.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
             FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF PMT
 
  The following discussion should be read in conjunction with PMT's
consolidated financial statements and notes thereto and "Selected Consolidated
Financial Data of PMT" included elsewhere in this Proxy Statement.
 
OVERVIEW
 
  PMT began operations in July 1986 to develop, manufacture and sell advanced
plasma technology products. From 1986 until 1990, PMT worked with Leybold and
commercialized PMT's Advanced Plasma Source (APS) technology that was
developed by Dr. Campbell while studying at UCLA. PMT receives royalties from
Leybold, which currently manufactures advanced optical coating equipment
utilizing PMT's APS technology. In 1990, PMT began development of a second
plasma technology, its MORI(TM) plasma source, and signed licensing and OEM
agreements with Alcan-Tech, an affiliate of Canon Sales, in November 1991,
with NEC Anelva in February 1992, with Leybold in December 1992, and with
Watkins-Johnson in December 1993. In December 1995, PMT agreed in principle
with NEC Anelva to extend its original OEM and licensing agreement so that the
two parties could jointly develop, manufacture and market an intermetal
dielectric CVD system based upon PMT's MORI(TM) source. PMT introduced its
plasma processing systems, the APEX 7000(R) and the PINNACLE 8000(R), in 1993,
and made its first shipments to end use customers beginning in June 1994. PMT
introduced and made its first shipments to end use customers of its PINNACLE
8000R(R) system in December 1995. When sold directly to end use customers, an
APEX 7000(R) system has a list price of approximately $1,000,000. PMT's
PINNACLE 8000(R) and PINNACLE 8000R(TM) systems have list prices ranging from
$1,800,000 to $2,800,000, and from $1,900,000 to $3,400,000, respectively,
depending upon the number of modules that are sold with the system.
 
  PMT generally recognizes sales upon shipment of its products. Accordingly,
PMT's product sales are significantly affected by the timing of product
shipments. See "Risk Factors--Quarterly Operating Results Affected by Many
Business Factors." In addition, PMT often allows customers to evaluate
systems, and since customers can return such systems to PMT at any time with
limited or no penalty, PMT does not recognize a sale of an evaluation system
until it has been accepted by the customer. See Notes 1 and 3 of Notes to
Consolidated Financial Statements. PMT's collection practices and credit terms
are consistent with industry practice and, with respect to sales of systems,
generally provide for a customer to be invoiced upon shipment, with a
substantial portion of the payment (typically 80% to 90%) due within a certain
amount of time thereafter, and with the balance of the system's purchase price
due upon final installation and acceptance.
 
  On August 29, 1995, PMT completed its initial public offering (the "Initial
Public Offering"), resulting in approximately $40.1 million of net proceeds to
PMT. In connection with the Initial Public Offering, the Board of Directors
approved a one-for-three reverse stock split of PMT's Common Stock. The
reverse stock split has been accounted for as if it had taken place as of the
earliest date presented. Effective August 29, 1995, all of the outstanding
shares of the preferred stock of PMT (13,337,219 shares) automatically
converted into 4,445,740 shares of Common Stock.
 
RECENT DEVELOPMENTS
 
  The semiconductor industry is currently experiencing a significant downturn,
which PMT anticipates will result in reduced demand for semiconductor
processing equipment and increased pricing pressure upon equipment
manufacturers, including PMT. Such reduced demand could adversely affect PMT's
product sales during the quarter ending September 30, 1996 and for subsequent
periods. The loss or delay of one or more system sales during any quarter,
including the current quarter ending September 30, 1996, would significantly
and adversely affect PMT's operating results for that quarter. See "Risk
Factors--Cyclicality of Semiconductor Industry" and "Risk Factors--Quarterly
Operating Results Affected by Many Business Factors." Additionally, during the
current quarter ending September 30, 1996, pricing pressure attendant to PMT's
first shipments of multiple production systems to a major semiconductor
manufacturer are expected to result in lower gross and operating margins for
the current quarter and, perhaps, for subsequent periods than those attained
by PMT during recent quarters.

(1) During 1994, PMT changed its fiscal year end from the last day of February
    to December 31. Information for the twelve months ended December 31, 1994
    (unaudited) is provided for comparison to the information for the year
    ended December 31, 1995. Information for the ten months ended December 31,
    1993 (unaudited) is provided for comparison to the information for the ten
    months ended December 31, 1994.
(2) On August 29, 1995, PMT completed its Initial Public Offering, resulting
    in approximately $40.1 million of net proceeds to PMT. The funds have been
    used to cover PMT's working capital needs, its investment in evaluation
    systems and capital expenditures, and to continue to expand its research
    and development and operational activities.
 
  Product Sales. Products sales for the six months ended June 30, 1996
increased 153% to $17.9 million compared to $7.1 million for the six months
ended June 30, 1995. Such increase in product sales resulted from the shipment
of one PINNACLE 8000(R) and eight PINNACLE 8000R(TM) systems, four MORI(TM)
sources and one process module for the six months ended June 30, 1996 compared
to two PINNACLE 8000(R) systems, twelve MORI(TM) sources and three process
modules shipped in the six months ended June 30, 1995. Product sales increased
to approximately $20.9 million for the year ended December 31, 1995 from
approximately $9.8 million for the twelve months ended December 31, 1994, an
increase of 113%. These increases were attributable to the market acceptance
of PMT's advanced plasma processing systems (primarily the PINNACLE 8000(R)
system). Shipments of these high density, low pressure plasma systems
increased to eight PINNACLE 8000(R) systems and one PINNACLE 8000R(TM) system
in fiscal 1995, compared to three PINNACLE 8000(R) systems and three APEX
7000(R) systems in the twelve months ended December 31, 1994. Product sales
increased to approximately $8.0 million for the ten months ended December 31,
1994 from approximately $4.4 million for the ten months ended December 31,
1993, an increase of 80%. The increase in the ten months ended December 31,
1994 was due primarily to increased sales of systems and MORI(TM) sources, as
well increased sales of spare parts. PMT had no sales of Apex systems during
the six-month period ended June 30, 1996 or during the year ended
 
                                      41
<PAGE>
 
December 31, 1995, and expects that most of its product sales in the near term
will be derived from sales of its newer PINNACLE 8000R(TM) system.
 
  International sales accounted for approximately 76%, 47%, 66% and 66% of
total revenue for the six months ended June 30, 1996, the year ended December
31, 1995, the ten months ended December 31, 1994 and the ten months ended
December 31, 1993, respectively. PMT anticipates that international sales will
continue to account for a significant portion of its total revenue. In
particular, PMT expects that product sales to Japanese and Korean
semiconductor manufacturers will continue to represent a significant
percentage of PMT's revenue through the remaining portion of fiscal 1996;
however, PMT's international sales as a percentage of its total revenue should
decrease in the future from historical levels, as PMT anticipates an increase
in the percentage of its product sales made to domestic customers. In
addition, because of the large unit price associated with PMT's systems, PMT
anticipates that its product sales will continue to be made to a small number
of customers in any given quarter. See Note 1 of Notes to Consolidated
Financial Statements.
 
  License Revenue. PMT has entered into licensing agreements with Leybold,
Canon Sales and NEC Anelva which grant certain rights for the use of PMT's
MORI(TM) technology. These agreements provide for an initial lump-sum license
payment and generally provide the licensee with the right, upon making further
payments, to expand the scope of the license. See "Business--Business of PMT--
Research, Development and Engineering."
 
  PMT received no license revenues in the six months ended June 30, 1996,
compared to $400,000 for the six months ended June 30, 1995, because all
revenues due to PMT under its existing license agreements have been paid. For
the year ended December 31, 1995, license revenue was $400,000 compared to
$700,000 for the twelve months ended December 31, 1994. For the ten months
ended December 31, 1994, license revenue was $700,000 compared to $1.9 million
for the ten months ended December 31, 1993. PMT does not anticipate the
receipt of any additional license revenue for at least the next twelve months.
However, PMT may enter into additional license agreements as it deems
appropriate in order to broaden the applications of its MORI(TM) technology,
or to improve PMT's market penetration.
 
  Contract Revenues. In March 1996, PMT entered into an agreement with a PMT-
sponsored limited partnership, owned by third party investors, except for
PMT's minority interest in the partnership, for the development and
distribution of an intermetal dielectric CVD system based on PMT's MORI(TM)
technology. Under the agreement, PMT is paid by the partnership for research
and development services rendered to the partnership. Approximately $849,000
was recognized as revenues for research and development charged to the
partnership during the first six months of fiscal 1996.
 
  Gross Margin on Product Sales. PMT's gross margin on product sales has
historically fluctuated and has been dependent primarily on the channels
through which sales are made in a particular period. In general, sales through
PMT's direct sales staff are normally made at higher selling prices than those
made through PMT's distributor and OEM channels. PMT's gross margin on product
sales increased to 49% for the six months ended June 30, 1996, as compared to
47% for the six months ended June 30, 1995. The improved margin is
attributable principally to the higher sales volume which resulted in
increased production efficiencies and to higher average selling prices. PMT's
gross margin on product sales was approximately 47% in fiscal 1995 as compared
to 34% for the twelve months ended December 31, 1994, approximately 33% for
the ten months ended December 31, 1994, and 27% for the ten months ended
December 31, 1993. The increase in the margin for 1995 and 1994 is
attributable to an increase in units shipped through PMT's direct sales staff,
which resulted in improved production efficiencies, and to a higher average
selling price.
 
  Research and Development Expenses. PMT believes that to remain in a strong
technological position in the industry, it is critical to continue to make
substantial investments in research and development. As PMT's revenue have
increased, its research and development expenses have become a smaller
percentage of total revenue. Research and development expenses including
expenses related to contract revenues, for the six months ended June 30, 1996
were $3.6 million, or 19% of net revenues, compared to $2.0 million, or 27% of
net revenues, for the six months ended June 30, 1995. PMT spent $4.6 million
or 22% of total revenue on research
 
                                      42
<PAGE>
 
and development related activities in fiscal 1995. The dollar increases in
expenses are attributable principally to PMT's continued investment in further
expanding MORI(TM) technology to develop new processes to meet customer
requests and requirements. This compared to $4.2 million or 40% of total
revenue in the twelve months ended December 31, 1994, $3.6 million or 41% of
total revenue for the ten months ended December 31, 1994, and $2.2 million or
35% of total revenue for the ten months ended December 31, 1993. The major
focus of PMT's research and development efforts during fiscal 1995 was using
PMT's proprietary plasma source technology to develop new processes for
advanced etch requirements. This led to the development and introduction into
production in December 1995 of an integrated stack etch process for an EEPROM
device and the foundation for development programs in Korea and Japan.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the six months ended June 30, 1996 were $4.3
million, or 23% of net revenues, compared to $2.7 million, or 37% of net
revenues, for the six months ended June 30, 1995. The increased expense was
due primarily to the continued growth in the organization's selling and
customer support centers and to PMT's Korean subsidiary's need to hire
additional employees in order to comply with the Korean semiconductor
manufacturers' requirement of having direct local representation for sales and
support. Selling, general and administrative expenses were $5.9 million or 28%
of total revenue in fiscal 1995. This compared to $3.9 million or 37% of total
revenue in the twelve months ended December 31, 1994, $3.4 million or 39% of
total revenue for the ten months ended December 31, 1994, and $1.7 million or
27% of total revenue for the ten months ended December 31, 1993. These dollar
increases are primarily due to the expansion of PMT's customer service
department to support the increased number of systems (including evaluation
systems) that were installed at customer sites worldwide. In addition, PMT
incurred increased selling expenses associated with the expansion of its sales
organization. As a percentage of sales, these expenses have become a smaller
percentage of revenue due to increased revenue. PMT anticipates that selling,
general and administrative expenses will grow in relation to the growth in
revenues.
 
  Income (Loss) from Operations. For the six months ended June 30, 1996, PMT
realized $1.8 million in income from operations, or 9% of total revenue for
such period, as compared to a loss of $1.0 million, or 14% of such total
revenue for the six months ended June 30, 1995. PMT realized a $364,000 loss
from operations, or 2% of total revenue in fiscal 1995, as compared with a
$4.1 million loss from operations, or 39% of total revenue in the twelve
months ended December 31, 1994. As a percentage of total revenue, the
operating loss has decreased due to the growth in revenue in addition to the
decrease in operating expenses as a percentage of total revenue. For the ten
months ended December 31, 1994, PMT sustained a $3.7 million loss from
operations, or 42% of revenue, as compared with a $757,000 loss from
operations, or 12% of total revenue, for the ten months ended December 31,
1993. As a percentage of total revenue, the operating loss increased due to
the expansion of PMT's research, sales and service departments.
 
  Interest Income (Expense). For the six months ended June 30, 1996, interest
income increased to approximately $884,000, as compared to $29,000 for the six
months ended June 30, 1995. Interest income increased to $777,000 in fiscal
1995 from $143,000 in the twelve months ended December 31, 1994, an increase
of 443%. The increase in interest income was due to income derived from the
proceeds of PMT's Initial Public Offering and resulted in PMT's profitability
in fiscal 1995, notwithstanding a $364,000 loss from operations. Interest
income increased to $125,000 for the ten months ended December 31, 1994 from
$15,000 in the ten months ended December 31, 1993, an increase of 733%, as
larger cash balances generated increased interest income.
 
  Interest expense increased to $294,000 in 1995 from $159,000 in the twelve
months ended December 31, 1994, an increase of 85%. This was due to higher
capital lease expenses combined with the utilization of a revolving bank line
of credit in the first two quarters of fiscal year 1995. For the ten months
ended December 31, 1994, interest expense of $146,000 decreased 31% compared
to $213,000 the ten months ended December 31, 1993 due to the limited use of
the line of credit.
 
  Income Taxes. For the six-month periods ended June 30, 1996 and 1995, the
year ended December 31, 1995 and the ten months ended December 31, 1994, PMT
has paid and provided for no or nominal amounts of income taxes due to
operating losses incurred or the utilization of net operating loss
carryforwards and the related
 
                                      43
<PAGE>
 
reduction in valuation reserves. The provision for income taxes in each period
differs from the statutory federal rate of 35% due to either the reduction of
the valuation allowance attributed to the utilization of the net operating
loss carryforwards or net operating losses incurred and not benefited. As of
December 31, 1995, PMT had research and development credit carryforwards of
approximately $800,000 and $300,000 for federal and state tax purposes,
respectively, that expire at various dates through 2010. PMT also had net
operating loss carryforwards at December 31, 1995, for federal and state
income tax purposes, of approximately $5.4 million and $2.7 million,
respectively, which expire at various dates through 2008. PMT's utilization of
its net operating loss and credit carryforwards depends upon future income and
is subject to an annual limitation, required by the Internal Revenue Code of
1986 and similar state provisions. See Note 6 of Notes to Consolidated
Financial Statements.
 
  Net Income (Loss). Net income for the six months ended June 30, 1996 was
$2.6 million, compared to a loss of $1.2 million for the six month period
ended June 30, 1995. Net income in fiscal year 1995 was approximately
$100,000, compared to a net loss of $4.1 million in the twelve months ended
December 31, 1994. The net income realized in 1995 was due primarily to the
$777,000 in interest income earned from the investment of Initial Public
Offering proceeds and the management of costs in relation to revenue in 1995.
Net loss in the ten months ended December 31, 1994 was $3.7 million as
compared to a $1.0 million loss in the ten months ended December 31, 1993 due
to the increase in PMT's operating expenses during the 1994 period.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  At June 30, 1996, PMT had $23.6 million in cash, cash equivalents and short-
term investments, compared to $38.8 million at December 31, 1995. This $15.2
million decrease was primarily due to increases in inventory and accounts
receivable. In addition, $4.8 million was invested in capital equipment as PMT
used funds to expand its applications laboratory to support process
development and customer demonstrations.
 
  At June 30, 1996, there were no borrowings outstanding under the revolving
credit line, and $3,000,000 was available for borrowings under that agreement.
The agreement has been recently extended and presently runs through June 5,
1997. The agreement places certain restrictions on PMT which, among other
things, prohibit PMT from paying cash dividends or repurchasing its stock, and
requires PMT to comply with certain financial ratios and covenants. PMT is
currently in compliance with all covenants and restrictions contained in the
revolving line of credit. PMT also has a $3,000,000 equipment leasing facility
that runs through December 30, 1996. At June 30, 1996 there were no borrowings
under the equipment leasing facility.
 
  PMT anticipates that it will spend approximately $6.8 million for capital
expenditures during fiscal 1996, of which $4.8 million has been invested in
capital equipment during the first six months of 1996. This is expected to
include investments in demonstration and test equipment, information systems,
and other capital items that should enable PMT to expand its ability to
support and develop new products and services. In addition, PMT expects to
increase its investment in inventory of evaluation systems at customer sites.
 
  In March 1996, PMT sponsored a partnership with certain third-party
investors to fund research and development costs and expenses relating to CVD
technology and applications. Third-party investors invested an aggregate of
approximately $5,350,000 in the partnership, which aggregate amount is
available to fund such costs and expenses. See "Business--Business of PMT--
Research, Development and Engineering" and Note 13 to "Notes to Consolidated
Financial Statements."
 
  While PMT's cash requirements will fluctuate based on the timing and extent
of the normal operation of the business, PMT believes that cash generated from
operations, together with the existing cash, cash equivalents, short-term
investments and borrowings under existing bank lines should be sufficient to
support its stand alone operations over the next 12 months, although there can
be no assurance in that regard.
 
  In connection with the consummation of the Acquisition, and to satisfy the
Working Capital Condition, PMT anticipates the establishment of the Working
Capital Facility which will be consistent with the requirements
 
                                      44
<PAGE>
 
of the Working Capital Condition. PMT believes that cash provided or available
from the Working Capital Facility and other sources of capital available to
PMT, including cash on hand, will be sufficient to support PMT's liquidity
needs over the next 12 months, including the working capital needs of PMT and
Electrotech on a going forward basis, although there can be no assurance in
that regard. See "Proposal No. 1--The Acquisition--Terms of the Acquisition
and Related Transactions--Terms of the Financing Arrangement; Working
Capital."
 
IMPACT OF INFLATION
 
  Although PMT cannot accurately anticipate the effect of inflation on its
operations, to date inflation has not had a material effect on PMT's product
sales or results of operations.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of
("SFAS No. 121"), which will be effective for PMT's fiscal year ending
December 31, 1996. SFAS No. 121 requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are
presented and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. SFAS No. 121 also addresses
the accounting for long-lived assets that are expected to be disposed of. PMT
adopted SFAS No. 121 for the annual reporting period of fiscal 1996 during the
first quarter ended March 31, 1996. No adjustments are required with respect
to such action.
 
  In October 1995, the FASB issued Statement of Financial Accounting Standards
No. 123, Accounting for Awards of Stock-Based Compensation to Employees ("SFAS
No. 123"), which will be effective for PMT's fiscal year ending December 31,
1996. SFAS No. 123 provides alternative accounting treatment to APB No. 25
with respect to stock-based compensation and requires certain additional
disclosures, including disclosures if PMT elects not to adopt the accounting
requirements of SFAS No. 123. PMT intends to make the additional disclosure
requirements of SFAS No. 123 for the annual reporting period of fiscal 1996,
but will elect to continue to measure compensation costs following present
accounting rules under APB No. 25. Consequently, PMT will provide pro forma
disclosures of what net income and earnings per share would have been had the
fair market value method of SFAS No. 123 been used for the relevant periods.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                           OPERATIONS OF ELECTROTECH
 
  The following discussion should be read in conjunction with the combined
financial statements of Electrotech and notes thereto and "Selected Combined
Financial Data of Electrotech" included elsewhere in this Proxy Statement. The
combined financial statements of Electrotech combine the consolidated
financial statements of each of ET and ETE, which are subject to common
control. The financial information for Electrotech has been prepared in
accordance with UK GAAP and in British pounds. See Note 29 of the notes to the
Electrotech combined financial statements for a reconciliation to US GAAP for
selected financial information.
 
BACKGROUND
 
  A privately-owned company, Electrotech was founded in 1968 by three
scientists from the European research division of ITT as a small manufacturer
of vacuum accessories. By 1980, the core technologies of Electrotech had been
developed to address plasma etch (1975), plasma enhanced CVD (1978) and PVD
(1980). Electrotech opened sales offices in the U.S. and continental Europe
markets in the 1970's, appointed its first sales agents in Japan in 1983 and,
thereafter, expanded into other areas of the Asia/Pacific region.
 
  In 1995, Electrotech sold its Surface Technology Systems Limited ("STS")
subsidiary to Sumitomo Precision Products Co. Limited, resulting in a gain of
(Pounds)5.0 million, before taxes, in the fiscal year ended June 30, 1995. The
proceeds from the sale of STS were used to fund a portion of a major expansion
program which included a move in 1996 into new corporate and manufacturing
headquarters in Newport, South Wales.
 
RESULTS OF OPERATIONS
 
  The following table sets forth for the periods indicated the percentage of
total revenues represented by certain line items in the combined profit and
loss accounts related to the operations of Electrotech:

COMPARISON OF THE YEAR ENDED JUNE 30, 1996 TO THE YEAR ENDED JUNE 30, 1995
 
REVENUES
 
  Total revenues were (Pounds)49.0 million for the year ended June 30, 1996
compared to (Pounds)34.5 million for the year ended June 30, 1995, an increase
of 42.0%. Total revenues included sales of (Pounds)3.8 million for the year
ended June 30, 1995 and no sales in the comparable period in fiscal 1996
related to STS.
 
                                      47
<PAGE>
 
  The increase in revenues is primarily due to sales of Sigma products. Units
shipped increased to 17 Sigma systems and five Forcefill(TM) modules in the
year ended June 30, 1996, compared to 15 Sigma systems and four Forcefill(TM)
modules in the year ended June 30, 1995. Revenues from these products were
(Pounds)26.5 million, representing 54.2% of total revenues in the year ended
June 30, 1996 compared to revenues of (Pounds)18.0 million, representing 57.9%
of total revenues (less STS revenues) in the year ended June 30, 1995.
Revenues from the sales of Sigma products increased by 47.2% between the two
years. The increase in revenues of approximately 47% from the sale of Sigma
products from year to year was primarily due to higher unit selling prices and
a reduction in the number of sales made through distributors.
 
  Revenues from sales of Planar 200 Flowfill(TM) products were (Pounds)4.6
million for the year ended June 30, 1996 and (Pounds)1.5 million for the year
ended June 30, 1995, an increase of 206%. Six Planar 200 Flowfill(TM) systems
were shipped during the year ended June 30, 1996, compared to the shipment of
two such systems during the year ended June 30, 1995.
 
  Revenues from sales of Omega(TM) and Delta products were (Pounds)7.3 million
and (Pounds)2.1 million for the year ended June 30, 1996 and were (Pounds)2.0
million and (Pounds)1.1, respectively, for the year ended June 30, 1995, an
increase of 265% and 91%, respectively, between the two periods. During the
year ended June 30, 1996, 14 Omega(TM) etch systems and five Delta systems
were shipped, compared to four Omega(TM) systems and four Delta systems,
respectively, during the year ended June 30, 1995. Unit prices on Delta
systems have significantly improved from year to year.
 
GROSS MARGIN
 
  Electrotech's gross margin was 52.2% in the year ended June 30, 1996 and
50.7% in the year ended June 30, 1995. Excluding sales and related costs of
sales of STS, the gross margin for the year ended June 30, 1995 was 51.9%. The
gross margins achieved by Electrotech were influenced primarily by changes in
product mix. Overall gross margins are also influenced by the portion of total
sales which are sold through distributors at reduced sales prices and the
impact of currency exchange rates on sales denominated in currencies other
than pounds sterling.
 
RESEARCH AND DEVELOPMENT EXPENSES
 
  Research and development expenses include costs associated with the
definition, design and development of new products. Research and development
expenses were (Pounds)6.7 million for the year ended June 30, 1996, compared
to (Pounds)4.4 million for the year ended June 30, 1995 (including (Pounds)0.3
million of STS expenses), an increase of 63.4% (excluding STS expenses). This
increase is primarily due to increased development costs on Forcefill(TM) and
Flowfill(TM) technologies, including an expenditure of (Pounds)1.0 million on
machines dedicated to research and development having an estimated useful life
of less than one year.
 
  Electrotech considers its research and development activities to be crucial
to its future success and, therefore, expects its research and development
expenditures to continue to rise in monetary terms, although not necessarily
as a percentage of sales.
 
ADMINISTRATIVE EXPENSES
 
  Administrative expenses consist of personnel costs and overhead for
administration, finance, sales and marketing, information systems, human
resources and general management. Administrative expenses were
(Pounds)8.3 million during the year ended June 30, 1996 compared to
(Pounds)8.6 million during the year ended June 30, 1995, a decrease of 3.7%
over such periods. Excluding administrative expenses and non-recurring
expenditures associated with the sale of STS, administrative expenses were
(Pounds)7.1 million during the year ended June 30, 1995. Significant
variations in expenditure between the two periods were in payroll costs, which
increased to (Pounds)3.4 million from (Pounds)2.8 million, an increase of
21.4%, and travel costs which increased to (Pounds)2.1 million from
(Pounds)1.5 million, an increase of 40%. Included in administrative expenses
for the year ended June 30, 1996 were currency exchange gains of
(Pounds)604,000 compared to currency exchange losses of (Pounds)73,000 for the
year ended June 30, 1995.

  In January 1996, Electrotech commenced partial occupation of new leased
premises in Newport, South Wales. Electrotech anticipates that the property
will be fully occupied by early 1997. Following full occupation of the
property the rental charge and depreciation of improvements will increase
administrative expenses by approximately (Pounds)1.2 million per annum.
Management anticipates that general and administrative expenses will continue
to increase in support of planned business expansion in markets outside the
United Kingdom.
 
INTEREST EXPENSE, NET
 
  Net interest expense was (Pounds)609,000 in the year ended June 30, 1996
compared to (Pounds)438,000 in the year ended June 30, 1995, an increase of
39.0% over such periods. The increase was primarily due to increased working
capital requirements necessary to fund the expansion of the business.
 
INCOME TAX EXPENSE
 
  Income tax expense was (Pounds)3.7 million in the year ended June 30, 1996
compared to (Pounds)3.5 million in the year ended June 30, 1995, an increase
of 5.7% over such periods. The effective tax rates were 37.1% and 39.0%,
respectively. The high effective tax rate for the year ended June 30, 1995 was
primarily due to a larger portion of earnings arising in countries with a
higher effective tax rate than the U.K.
 
COMPARISON OF THE YEAR ENDED JUNE 30, 1995 TO THE YEAR ENDED JUNE 30, 1994
 
REVENUES
 
  Total revenues, exclusive of STS revenues, were (Pounds)30.7 million in the
fiscal year ended June 30, 1995 compared to (Pounds)18.4 million in the year
ended June 30, 1994, an increase of 66.9%. The increase in revenues was
primarily attributable to increased sales of Sigma products. Shipments
increased to 15 Sigma systems and four Forcefill(TM) modules in fiscal 1995,
compared to four Sigma systems and one Forcefill(TM) module in fiscal 1994.
Revenues from these products were (Pounds)18.0 million in fiscal 1995 compared
to (Pounds)5.2 million in fiscal 1994, an increase of 246.2%.
 
  Revenues from sales of Planar 200 Flowfill(TM) products were (Pounds)1.5
million for the year ended June 30, 1995 and (Pounds)1.3 million for the year
ended June 30, 1994. Two Planar 200 Flowfill(TM) systems were shipped in each
of fiscal year 1995 and 1994.
 
  Revenues from sales of Omega(TM) and Delta products in fiscal 1995 were
(Pounds)2.0 million and (Pounds)1.1 million, respectively, compared to
(Pounds)2.7 million and (Pounds)631,000, respectively, in fiscal 1994, a
decrease of 25.9% and an increase of 74.3%, respectively. During fiscal 1995
four Omega(TM) systems and four Delta systems were shipped, compared to five
Omega(TM) systems and two Delta systems in fiscal 1994.
 
  Revenues from STS were (Pounds)3.8 million in fiscal 1995, compared to
(Pounds)5.4 million in fiscal 1994.
 
GROSS MARGIN
 
  Gross margin was 50.7% and 51.7% for the years ended June 30, 1995 and 1994,
respectively. The gross margins achieved by Electrotech was influenced by
changes in product mix, the portion of total sales which are sold through
distributors at reduced sales prices and the impact of currency exchange rates
on sales denominated in currencies other than pounds sterling.
 
RESEARCH AND DEVELOPMENT EXPENSES
 
  Research and development expenses, exclusive of expenses of STS, were
(Pounds)4.1 million in the year ended June 30, 1995, compared to (Pounds)2.8
million in the year ended June 30, 1994, an increase of 46.4%. The increased
expenditure was primarily attributable to research and development of the
Forcefill(TM) and Flowfill(TM) technologies. Research and development expenses
as a percentage of revenues were 12.8% in fiscal 1995 compared with 14.0% in
fiscal 1994.
 
                                      49
<PAGE>
 
ADMINISTRATIVE EXPENSES
 
  Administrative expenses, exclusive of expenses of STS, were (Pounds)7.5
million in the year ended June 30, 1995 compared to (Pounds)5.4 million in the
year ended June 30, 1994. Excluding a non-recurring expenditure associated
with the sale of STS, administrative expenses in fiscal 1995 amounted to
(Pounds)7.1 million, an increase of 31.5% from fiscal 1994.
 
INTEREST EXPENSE, NET
 
  Net interest expense was (Pounds)438,000 and (Pounds)255,000 in the fiscal
years ended June 30, 1995 and 1994, respectively. The increases were primarily
due to increased working capital requirements due to the expansion of the
business.
 
INCOME TAX EXPENSE
 
  Worldwide income tax expense was (Pounds)3.5 million in the fiscal year
ended June 30, 1995. This amount included (Pounds)2.0 million in respect of
the gain on the sale of STS. The effective tax rate was 39.0% in the year
ended June 30, 1995. Income tax expense was (Pounds)574,000 in fiscal 1994, an
effective tax rate of 36.7%.
 
WORLDWIDE TAX EXPENSE
 
  ET and ETE each operate as a holding company. ET and its subsidiaries
operate in the United Kingdom. ETE has operating subsidiaries in several
countries, and each subsidiary is taxed based on the laws of the jurisdiction
in which it operates. Because taxes are incurred at the subsidiary level, and
one subsidiary's tax losses cannot be used to offset the taxable income of
subsidiaries in other jurisdictions, ETE's consolidated effective tax rate may
increase to the extent it reports tax losses in some subsidiaries and taxable
income in others. The subsidiaries are subject to taxation in countries where
they operate, and such operations generally are taxed at rates similar to or
higher than tax rates in the United Kingdom. The payment of dividends or
distributions by the subsidiaries to ETE would be subject to withholding taxes
in the country of domicile and may be mitigated under the terms of relevant
double tax treaties with the United Kingdom.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  To date, Electrotech has funded its operations principally through cash flow
from operations and short- and medium-term bank borrowings. At June 30, 1996,
Electrotech had (Pounds)2.1 million of cash, a bank revolving credit line of
(Pounds)8 million (of which (Pounds)7.9 million was outstanding), including
bank guaranties made on behalf of Electrotech, and a medium-term bank loan of
(Pounds)800,000. Electrotech's revolving credit line expired on March 31,
1996, though such line has been orally extended by the lender pending the
outcome of the Acquisition.
 
  Net cash provided by operating activities was (Pounds)4.9 million for the
year ended June 30, 1996 against a net outflow from operating activities of
(Pounds)3.3 million in the year ended June 30, 1995. Net cash outflows from
operating activities were (Pounds)2.7 million in fiscal 1994. The net cash
inflows and outflows from operating activities reflect movements in the
working capital of Electrotech.
 
  Net cash used in investing activities was (Pounds)4.8 million in the year
ended June 30, 1996. This was primarily due to capital expenditure at the new
premises at Newport, South Wales. There was a net cash inflow from investing
activities of (Pounds)4.1 million in the year ended June 30, 1995, comprised
of an inflow of (Pounds)6.6 million from the sale of STS less capital
expenditures of (Pounds)2.5 million. The net cash used in investing activities
was (Pounds)745,000 in fiscal 1994. Net cash used in financing activities was
(Pounds)188,000 in the year ended June 30, 1996. Net cash used in financing
activities was (Pounds)400,000 in both fiscal 1995 and fiscal 1994. All cash
used in financing relates to repayments made against the medium-term bank
loan.
 
  Due to recent growth in Electrotech's sales and its development of new
products, Electrotech's existing facilities have reached their capacity limit.
Electrotech has leased a 102,000 square foot facility into which it
 
                                      50
<PAGE>
 
moved certain of its sales, customer support and financing operations in
January 1996. Approximately 20,000 square feet of the facility are currently
in use, and the remaining space is being built out with a view to full
occupancy in early 1997. The rental of the new premises is (Pounds)500,000 per
annum.
 
  Electrotech expects to incur capital expenditure of approximately
(Pounds)5.5 million during the next 12 months of which approximately
(Pounds)4.0 million will relate to build out of the new facility.
 
  Assuming that the Acquisition is not consummated, as a stand alone entity,
Electrotech will likely need to obtain additional debt or equity financing to
fund its future working capital obligations and cash flow needs.

  The accompanying unaudited pro forma financial statements include
adjustments for the allocation of the purchase price to the underlying assets
and liabilities as discussed below, the issuance of Common Stock, the
elimination of Electrotech's equity in combination of the two companies,
depreciation and amortization of the amounts allocated to various assets and
liabilities acquired and a reduction of interest income and increase in
interest expense associated with the reduction of cash and the issuance of the
Convertible Notes in connection with the Acquisition.
 
  The unaudited pro forma financial information presented above combines the
June 30, 1996 balance sheets of PMT and Electrotech and the statements of
operations for the twelve month period ended December 31, 1995 and the six
month period ended June 30, 1996 on a pro forma basis. This pro forma
combination gives effect to the following assumptions:
 
  . That the Acquisition occurred on June 30, 1996 for the unaudited pro
    forma balance sheet.
 
  . That the Acquisition occurred as of the beginning of each statement of
    operations presentation with the allocation of the purchase price
    estimated based on the June 30, 1996 unaudited combined balance sheet of
    Electrotech.
 
  . That the Acquisition would be accounted for as a purchase.
 
  . That the purchase price paid by PMT to acquire Electrotech would be
    approximately $154.2 million, consisting of $75 million in cash, 5.6
    million shares of Common Stock valued at $12.625 per share, and that the
    estimated transaction and financing costs would be $8.5 million. The
    valuation of Common Stock is based on the $12.625 per share closing price
    of Common Stock on July 17, 1996, the last day prior to the public
    announcement of the parties' agreement to acquisition terms.
 
                                      54

  . That $65 million of cash required to consummate the Acquisition would be
    financed through the issuance of Convertible Notes, which will bear
    interest at 7.5% per annum. The actual amount financed and the terms of
    the financing may differ from the amount used in the pro forma financial
    statements.
 
  . That the excess of the purchase price including the estimated transaction
    and financing costs, over the net shareholders' equity of Electrotech
    would be allocated to the following assets and liabilities and that the
    amounts allocated would be amortized over the following time periods:

    . Goodwill.....................   1,688 Ten years
   Deferred tax liability..........  17,787 As utilized based on the above lives
</TABLE>
 
  . The preliminary allocation of the purchase price among identifiable
    tangible and intangible assets and liabilities, as reflected in the
    accompanying pro forma financial statements, is based on an analysis of
    the estimated fair value of those assets and liabilities as of June 30,
    1996. The estimated fair market value of the assets acquired may vary
    significantly between June 30, 1996 and the Closing.
 
    Purchased in-process technology was analyzed through interviews and
    analysis of data concerning each of Electrotech's projects in development
    (i.e. Forcefill(TM) and Flowfill(TM)). Expected future cash flows of the
    developmental projects were discounted to present value taking into
    account risks associated with the inherent difficulties and uncertainties
    in completing the projects, and thereby achieving technological
    feasibility, and the risks related to potential changes in future target
    markets. PMT's expected post-acquisition business strategies were
    considered as they relate to Electrotech's current products and projects
    in development. Considerable efforts are being applied by Electrotech to
    its Forcefill(TM) and Flowfill(TM) projects to attain product
    functionality and reliability levels acceptable to their intended target
    market.
 
    The write-off of purchased in-process technology is not reflected in the
    accompanying unaudited statements of operations as it is a non-recurring
    charge. It will be included, however, in the actual consolidated statement
    of operations of PMT for the first fiscal quarter in which the Acquisition
    occurs.
 
    Using the methodology that was used for in-process technology, expected
    future cash flows of the developed technology were discounted taking into
    account risks related to the characteristics and application of each
    product, existing and future markets, and assessments of the life cycle
    stage of each product. This analysis resulted in an estimated value of
    $45.9 million for developed technology, which has reached technological
    feasibility and therefore would be capitalized.
 
  . For United States income tax purposes, the tax basis of the underlying
    assets and liabilities is not adjusted. Accordingly, a deferred tax
    liability has been included in the purchase price allocation which
    represents the tax effect of the difference in the basis for financial
    reporting and tax purposes of the assets, except goodwill, and
    liabilities acquired, after considering the effects of the purchase price
    allocation. The portion of the tax credit associated with the
    amortization of the excess of the recorded basis of the assets is
    reflected as a tax benefit in the accompanying pro forma statements of
    operations.

  . The number of shares used in the computation of earnings per share has
    been adjusted to reflect the issuance of 5,600,000 shares of Common Stock
    in connection with the Acquisition as if it had occurred at the beginning
    of the year presented. Fully dilutive earnings per share data has not
    been presented because such data would be anti-dilutive. See note 1 to
    the audited Financial Statements of PMT for the year ended December 31,
    1995.
 
  It should be noted that the unaudited pro forma financial information:
 
  . Uses a pro forma allocation of the purchase price paid for Electrotech as
    shown above; both the allocation of the actual purchase price and the
    amortization periods for these amounts are preliminary and subject to
    refinement pursuant to completion and updating of valuation studies at
    the time of closing.
 
  . Does not give effect to any costs of combining the companies or to any
    efficiencies in operations that could be achieved by combining the
    companies.
 
  . Does not purport to be indicative either of the results of operations
    that would have occurred had the Acquisition been consummated at the
    dates indicated, or of the future combined results of operations of the
    companies.
 
  . The financial data of PMT for the year ended December 31, 1995 used to
    develop the unaudited pro forma combining statement of operations is
    derived from the historical audited financial statements of PMT.
 
  . All interim financial data of PMT and Electrotech, and the financial data
    of Electrotech for the twelve month period ended December 31, 1995 used
    to develop the unaudited pro forma combining balance sheet and statements
    of operations is derived from historical unaudited financial statements
    of PMT and Electrotech, but in the opinions of management of PMT and
    Electrotech, respectively, reflect all adjustments necessary (consisting
    only of normal recurring entries) for a fair presentation thereof. The
    interim financial data and the financial data for the twelve month period
    ended December 31, 1995 for Electrotech have been adjusted to conform
    with U.S. generally accepted accounting principles and have been
    converted to U.S. dollars using the following U.S. dollar conversion
    rates per (Pounds)1 sterling: June 30, 1996--$1.53 and December 31,

                                   BUSINESS
 
SEMICONDUCTOR INDUSTRY OVERVIEW
 
  The semiconductor industry has experienced significant growth in recent
years due to an increasing demand for semiconductors. This demand has resulted
from the growth of existing markets such as personal computers,
telecommunications, consumer electronics, automotive electronics and office
equipment, as well as the development of applications such as multimedia,
wireless communications and portable computing. The growth in these markets
is, in part, limited by the semiconductor industry's ability to provide
increasing performance (as measured by functionality, processing speed and
memory) at a declining cost per function.
 
  The market demand for higher performance and higher density semiconductor
devices is pushing the limits of semiconductor wafer processing technology. As
customers demand higher processing speeds and greater memory capacity at
reduced costs, semiconductor manufacturers are forced to reduce feature size
in order to provide greater performance on an integrated circuit (IC) of a
given size. ICs are already highly complex, built-up from ten to thirty thin
layers, incorporating submicron (less than 1 micron) feature sizes, and
requiring up to 300 separate processing steps. In the next few years, the
requirements of advanced ICs will increase the number of thin film layers,
reduce film thickness, reduce feature sizes to 0.25 micron and smaller and
increase the number of processing steps. Semiconductor manufacturers must be
able to deliver these more advanced devices while maintaining acceptable
manufacturing performance characteristics, such as high yield and throughput.
 
SEMICONDUCTOR MANUFACTURING
 
  As ICs have become more complex, both the number and price of process tools
required to manufacture semiconductors have increased. In addition, the higher
complexity of ICs has increased significantly the value added by the
semiconductor manufacturer to the wafer during processing. As a result, the
cost of processed wafers has increased dramatically since the 1980s. The
increased investment required by semiconductor manufacturers, in terms of both
processing equipment cost as well as investment per wafer, has caused these
manufacturers to focus more closely on the performance and cost of ownership
associated with each piece of processing equipment.
 
  Semiconductor manufacturers use a broad range of processing equipment in the
fabrication of ICs to perform a number of complex and repetitive processing
steps, including deposition, photolithography and etch. Deposition is a
process in which a film of either electrically insulating (dielectric) or
electrically conductive material (e.g., metal) is deposited on the surface of
a wafer. The two principal methods of deposition are chemical vapor deposition
(CVD), which uses gaseous sources to deposit insulating or conductive thin
films on the wafer, and physical vapor deposition (PVD or commonly referred to
as "sputtering"), which is used primarily for depositing conductive metals
onto the wafer. Photolithography is then used to imprint complex circuit
patterns onto the wafer using a layer of light sensitive polymer material
known as photoresist. Once photolithography is completed, the wafer then
enters the etch process in which materials are selectively etched away from
areas which are not covered by the photoresist pattern. PMT's processing
equipment has historically targeted the etch process, while Electrotech has
extensive experience in developing and manufacturing equipment for deposition
(both CVD and PVD) and etch.
 
DEPOSITION TECHNOLOGIES
 
  The driving force behind the development of current and next-generation
deposition technologies is the need for faster semiconductor processing speed
and increased functional complexity of the ICs. This need, together with cost
considerations that require efficient manufacturing technologies, will
continue to determine the equipment selected by semiconductor manufacturers.
 
  As processing speed requirements have increased and the feature sizes of ICs
have decreased, the determining factor in ultra large scale integration IC
speed is no longer transistor switching speed but rather the electrical
properties of the interconnect deposited on the semiconductor. As critical
dimensions shrink below
 
                                      57
<PAGE>
 
0.5 micron, speed is limited by the resistance and capacitance of the
interconnection between the transistors. Accordingly, the Semiconductor
Industry Association's "national technology road map" calls for metallization
schemes with lower resistance and dielectric layers with lower dielectric
constants and, accordingly, lower capacitance. Additionally, shrinking feature
size increases the need for flat, or "planarized," layers to permit the
subsequent photoresist patterning of smaller features. Furthermore, at these
reduced geometries it becomes increasingly difficult to successfully establish
vertical conducting connections through the smaller patterned holes, or
"vias," in the insulating layers of the IC, and as conducting lines get closer
together it is more difficult to fill the smaller gaps between them with
insulating material.
 
  Aluminum has traditionally been used as the interconnect in contact holes,
vias and metal layers on an IC. As feature sizes decreased below one micron,
however, traditional aluminum PVD techniques became ineffectual due to their
inability to fill small holes. Device manufacturers were therefore forced to
utilize a process of filling contact holes and vias with tungsten and then
depositing a final interconnect layer of aluminum. This process is much more
complex than traditional aluminum PVD, involves a highly corrosive and
poisonous gas and produces a relatively large number of particles which
decrease yield. Furthermore, the high resistivity of tungsten compromises
device speed. Finally, the drive to increase packing density has led to the
use of vertically "stacked" vias which requires a high level of planarization
of the metal layers, which is difficult to achieve with a tungsten plug
process. These fundamental limitations of tungsten have caused a shift back to
aluminum-based plug and wiring schemes. Toward this end, new process
techniques involving the chemical vapor deposition of aluminum are the subject
of continued research efforts, but, to date, have failed to achieve the high
level of quality and reliability demanded by semiconductor manufacturers.
 
  Electrotech's new Forcefill(TM) technology is designed to replace the
multistep tungsten-fill approach with a single process of aluminum PVD that
both fills and interconnects the gaps with aluminum, resulting not only in
superior performance to the tungsten-plug method but also lower manufacturing
cost, due to reduced equipment requirements. Also, as many semiconductor
manufacturers design ICs with stacked vias, the high planarization of the
Forcefill(TM) process permits such stacking without requiring chemical
mechanical polishing (CMP) of the metal, which would be needed using tungsten-
plug technology.
 
  Prevailing intermetal dielectric deposition technologies include spin on
glass (SOG) and high density plasma (HDP) deposition followed by CMP.
Electrotech offers its Flowfill(TM) single-step CVD process that eliminates
the need for CMP on some device types. SOG requires single or multiple spins,
a technique which is complex and slow, and thus relatively expensive. HDP
dielectric deposition, including applications currently being addressed by PMT
through a joint development agreement with NEC Anelva (See "Business of PMT--
Joint Development Arrangements"), produces a superior quality of dielectric
needed for certain applications, although deposition rates are slower and the
process requires a second step (CMP) to achieve planarization. Alternatively,
with Flowfill(TM) the plasma CVD films are deposited in one process module and
a CVD planarizing layer is deposited in the Flowfill(TM) module with no vacuum
breaks between the process steps, reducing process complexity.
 
ETCH TECHNOLOGIES
 
  Virtually all etching processes use plasma technologies, in which a
semiconductor wafer is exposed to a plasma composed of a reactive gas which
etches away portions of the layer underlying the patterned photoresist layer.
Three properties of a plasma--density, pressure and energy--determine the
suitability of a given plasma process for semiconductor manufacturing. PMT's
patented MORI(TM) technology has the ability to provide a highly efficient
plasma, exhibiting high density (thereby achieving increased etch rates and
higher wafer throughput), while operating at low pressure (resulting in
superior etch features) and low energy (resulting in limited damage to the
wafer). This is achieved through the MORI(TM) source, which uses a helicon
antenna which is remote from the wafer to generate a radio frequency wave into
the plasma, a process which produces a high density of electrons and ions and
allows a reduction in the pressure of neutral gas molecules. Reactive ion
etching (RIE), an alternative technology, generates the plasma by a power
source that drives a current through a gas between two electrodes, with a
wafer placed on the powered electrode, a process which requires high gas
 
                                      58
<PAGE>
 
pressure and produces a low density plasma. Because of these limitations of
RIE when used on sub-0.5 micron features, a number of PMT's competitors have
developed their own high density, low pressure plasma sources, including
inductively coupled plasma (ICP) sources (such as the Omega(TM) etch product
of Electrotech) and the ECR plasma wave approach used by Hitachi.
 
COMBINED PRODUCT OFFERINGS
 
  The acquisition of Electrotech will provide PMT with new and promising
proprietary technologies in three critical segments of the semiconductor
industry: etch, PVD and CVD. As shown in the following table, Electrotech's
Forcefill(TM) PVD and Flowfill(TM) CVD products are complementary to PMT's
MORI-based plasma etch products:

* Incorporates PMT's MORI(TM) plasma source
 
  PMT's MORI(TM)-based etch products compete to a limited extent with
Electrotech's Omega(TM) etch product. PMT and Electrotech intend to continue
to support their respective product lines in the etch market. PMT is currently
in the process of developing an HDP dielectric deposition product that will
compete with Electrotech's Planar 200 Flowfill(TM) product in certain
applications. The success and market acceptance of these distinct CVD products
is presently unpredictable. Management believes that, with products based on
distinct CVD technologies, the combined company will be well positioned to
take advantage of the ultimate technological demands of the CVD market.
 
  By combining PMT's sales and distribution network in the U.S. and Asia with
Electrotech's historical strength in Europe, PMT will have access to a
substantially larger marketing, sales, support and service force throughout
the world. Management expects that the ability of this global sales force to
cross sell both PMT and Electrotech products to common customers will allow
PMT to compete more effectively with its larger competitors.
 
BUSINESS OF PMT
 
 Introduction
 
  PMT designs, manufactures and markets advanced high density, low pressure
plasma sources, process modules and plasma processing systems. These products
are used for etch and CVD applications and are sold to semiconductor and flat
panel display manufacturers worldwide. PMT currently offers a modular line of
etch equipment which utilizes the MORI(TM) source for polysilicon and metal
etch applications in the fabrication of semiconductor devices. In addition,
semiconductor manufacturers use the MORI(TM) source for plasma CVD of silicon
dioxide films and photoresist stripping. Certain other manufacturers also use
the MORI(TM) source for the plasma etching of films in the fabrication of
large area active matrix liquid crystal displays.
 
 Plasma Technologies
 
  Plasma is generated when a power source transfers energy to a gas, or more
specifically, by the ionization of gas through energetic electron bombardment.
Plasma consists of negatively charged (electrons), positively charged (ions)
and neutral atoms or molecules, and can be most simply defined in terms of
three physical properties: density, pressure and energy. Density describes the
average number of electrons in a given volume; pressure describes the number
of neutral atoms or molecules in a given volume; and the energy of the charged
particles is very dependent on how the external power is coupled into the
plasma and on the neutral gas pressure.
 
                                      59

Each of these physical properties is interrelated, and a change in one will
typically produce a corresponding change in the other two.
 
  During a plasma etch process (also known as "dry" etch), a semiconductor
wafer is exposed to a plasma composed of a reactive gas, such as chlorine,
which etches away selected portions of the layer underlying the patterned
photoresist layer. The energy of the gas particles that are reacting with the
layer is increased when that gas is in a plasma state, and this increases the
ability of the reactive gas to etch away the selected portions of the layer to
which the process is being applied. In addition, when in a plasma state, the
reactive gas ions in the plasma strike the surface of the wafer at a
perpendicular angle, which greatly increases the vertical etch rate. The three
properties of a plasma (density, pressure and energy) also define how suitable
a given plasma process may be for semiconductor manufacturing.
 
    Density: For semiconductor manufacturing, a higher density plasma is
  generally preferable to a lower density plasma. A higher density plasma
  increases the number of plasma particles reacting with the layer being
  etched, which increases the rate at which the wafer is etched, resulting in
  higher throughput (the rate at which wafers are processed).
 
    Pressure: In general, as the critical dimensions of the features on a
  semiconductor device continue to decrease in size to 0.35 micron and
  smaller, lower pressure plasma processing is required in order to produce
  acceptable yield (the fractions of wafers, and devices on each wafer, that
  are of acceptable quality) and throughput. First, as critical dimensions
  shrink, the ability to etch wafers with more precision, so that the
  sidewalls of features are nearly vertical and have minimal undercutting, is
  critical for producing acceptable yield. In addition, as ICs become more
  complex and are designed with features of varying dimensions, an effect
  known as microloading can occur in high pressure systems. Microloading, the
  effect of etching larger features more rapidly than smaller features,
  generally results from high pressure etching and can significantly decrease
  manufacturing yield.
 
    Ion Energy: For a number of reasons, low energy ions reacting with the
  wafer are preferable to high energy ions during the semiconductor
  manufacturing process. Fabrication processes which bombard the wafer with
  high energy ions can damage the wafer, cause particulates to form on the
  wafer, or cause electric charges to build up on device structures, all of
  which lead to lower manufacturing yields. In addition, fabrication
  processes must precisely control the thickness of the various material
  layers on the wafer, and it is necessary to be able to etch one layer
  without etching the underlying layers. A process that is able to meet this
  requirement is said to have a high selectivity, and processes utilizing low
  energy ions tend to have a higher level of selectivity, and therefore
  produce higher yields, than processes using high energy ions.
 
  PMT's patented MORI(TM) source enables PMT to provide equipment which
delivers high yield, high throughput etching with minimal wafer damage. Key
features of MORI(TM) technology include the ability to (i) provide a highly
efficient plasma that exhibits high density, high selectivity and high
uniformity, (ii) operate at low pressures, which results in less undercutting,
fewer particles, more vertical sidewalls, and the absence of microloading, and
(iii) operate at low energy, which results in limited damage to the wafer.
Each of these features contributes significantly to higher yield and
throughput.
 
  PMT believes that the advantages offered by its high density MORI(TM)
technology can best be understood by comparing it with existing reactive ion
etching (RIE) technology. An RIE plasma is generated by a power source that
drives current through a gas between two conducting electrodes, with a wafer
placed on the powered electrode. This results in a high voltage on the wafer
and the formation of a weakly ionized plasma. The electrons are accelerated by
this high voltage, and collide with the neutral gas molecules, creating ions,
more electrons and energetic gas atoms. The rate of plasma generation depends
on the number of these collisions. The high energy of the electrons requires a
high gas pressure to ensure that these collisions occur. At too low a
pressure, the electrons would miss the gas molecules, be lost to the chamber
wall, and the plasma would extinguish. This method of coupling energy to the
electrons by driving high voltage on the wafer requires high pressure.
Furthermore, the coupling of energy to the plasma in an RIE system is
relatively inefficient, resulting in a low plasma density.
 
                                      60
<PAGE>
 
  By contrast, PMT's MORI(TM) plasma source does not rely on a high voltage
source to give energy to the electrons. Instead, the MORI(TM) source utilizes
an antenna which is remote from the wafer to launch a radio frequency wave
into the plasma. The speed at which this wave propagates in the plasma can be
controlled through the frequency selected and the design of the antenna. By
matching the speed of the wave to the speed of the electrons in the plasma,
the electrons can "surf" on the wave and gain energy very efficiently. This
method of plasma generation produces a high density of electrons and ions and
allows a reduction in the pressure of neutral gas molecules. In fact, the
plasma density is only limited by the loss rate of plasma to the chamber
walls, which can be minimized by providing a magnetic field near the chamber
wall using permanent magnets that reflect the electrons back into the plasma.
 
  In light of the limitations of RIE technology when used on sub-0.5 micron
features, other semiconductor equipment manufacturers such as Applied
Materials, Lam Research and Hitachi have developed and sold their own high
density, low pressure plasma sources. For example, both Applied Materials and
Lam Research are using ICP sources in various configurations (as does
Electrotech in its Omega(TM) ICP product), and Hitachi uses a plasma wave
approach known as electron cyclotron resonance (ECR).
 
 Products
 
  PMT offers a line of modular solutions which are designed to meet the
varying requirements of its customers for etching of polysilicon, metal and
oxide films, stripping of photoresist, and CVD of oxide films. PMT's line of
equipment includes the MORI(TM) plasma source, the MORI(TM) stand-alone
process module for etch, strip or CVD applications, the APEX 7000(R) system,
the PINNACLE 8000(R) system, and the PINNACLE 8000R(TM) system. All of PMT's
systems products are Manufacturing Equipment Standard Configuration (MESC)
compatible.
 
  PMT's MORI(TM) plasma source is currently sold as a subsystem on a limited
geographic and application basis to OEM licensees of PMT's MORI(TM)
technology. PMT currently sells the MORI(TM) source to Leybold of Germany for
incorporation into Leybold's systems that are sold worldwide for etching large
area, active matrix liquid crystal displays. PMT sells its MORI(TM) source to
Canon Sales for incorporation into Canon Sales' systems for photoresist
stripping that are sold in the Japanese and Korean markets, and to NEC Anelva
for incorporation into NEC Anelva's systems for metal and oxide etching that
are sold in the Japanese market.
 
  PMT's stand-alone process module, common to PMT's APEX 7000(R), PINNACLE
8000(R) and PINNACLE 8000R(TM) systems, incorporates the MORI(TM) plasma
source and can be configured for etch, strip or CVD applications. The process
module can be sold to customers either to increase the capacity of existing
system platforms, or to provide additional process capability. The process
module requires less than eight square feet of floorspace. List price for a
standard process module configured for etch applications is currently
$500,000.
 
  The APEX 7000(R) is a single module, single wafer cassette, vacuum
loadlocked system for development, evaluation or single chamber production
applications. System throughput varies depending on the film application, and
is typically 20-30 wafers per hour for this single chamber configuration as
compared to a throughput of 15-20 wafers per hour for competitive single
module systems. Floorspace required for the APEX 7000(R) is approximately 26
square feet. List price for a standard APEX 7000(R) system is currently
$1,000,000.
 
  In December 1995, PMT introduced its PINNACLE 8000R(TM) cluster tool
platform, a more compact version of its existing PINNACLE 8000(R) system that
includes certain additional features that enable increased ease in operation.
Each of PMT's PINNACLE 8000(R) and PINNACLE 8000R(TM) systems is a dual wafer
cassette, vacuum loadlocked cluster tool which can incorporate up to four
MESC-compatible process modules. The dual wafer cassette loadlock
configuration enables the system to continuously process wafers. System
throughput varies, and is primarily dependent on the film application, the
operating configuration and the number of process modules attached to the
system. For a typical polysilicon etch process, with each process module
performing the same process, throughput varies from 40-60 wafers per hour for
a two module configuration, to 70-90 wafers per hour for a four module
configuration. This compares to a throughput of 30-40 wafers per hour for
competitive two
 
                                      61
<PAGE>
 
module systems. Floorspace required for a PINNACLE 8000R(TM) is approximately
44 square feet with two process modules and 65 square feet with four process
modules. By comparison, floorspace required for a PINNACLE 8000(R) is
approximately 88 square feet with four process modules. List price for the
PINNACLE 8000(R) and PINNACLE 8000R(TM) currently ranges from $1,800,000 for a
standard two module system to $2,800,000 for a four module system, and
$1,900,000 for a standard two module system to $3,400,000 for a four module
system, respectively.
 
 Customers
 
  PMT markets its systems to semiconductor manufacturers located throughout
the United States, Europe, Japan, Korea and Asia/Pacific. The following is a
list of customers who have purchased or leased PMT products either directly
with PMT or through its distribution and OEM relationships:
 
<TABLE>
   <S>                               <C>                                <C>
   AT&T                              Hyundai                            Samsung
   Daewoo                            IBM                                Sharp
   Dallas Semiconductor              LG Semicon                         Texas Instruments
   Fujitsu                           LSI Logic                          TriQuint
   Hitachi                           NEC                                Toshiba
                                     OKI
</TABLE>
 
  PMT has received multiple purchase orders for MORI(TM) plasma sources for
etch applications from NEC, OKI, and Sharp, and has received repeat orders for
a PINNACLE 8000R(TM) system from Hyundai and Dallas Semiconductor. PMT shipped
its first beta (pre-production evaluation) PINNACLE 8000(R) and APEX 7000(R)
plasma etch systems in 1993. PMT's first shipments of plasma etch systems to
end use customers began in June 1994, and PMT's first shipments of its
PINNACLE 8000R(TM) system began in December 1995.
 
  PMT's total revenue includes amounts from certain individual customers that
exceed 10% of total revenue. Revenue from five customers represented 19%, 15%,
12%, 11% and 11% each of total revenue for the year ended December 31, 1995,
revenue from six customers represented 19%, 17%, 17%, 15%, 15% and 12% each of
total revenue for the ten months ended December 31, 1994, and revenue from two
customers represented 46% and 39% each of total revenue for the year ended
February 28, 1994.
 
  International sales accounted for approximately 47%, 66% and 50% of total
revenue in the year ended December 31, 1995, the ten months ended December 31,
1994, and the year ended February 28, 1994, respectively. PMT anticipates that
international sales will continue to account for a significant portion of its
total revenue. In particular, PMT expects that sales to Japanese and Korean
semiconductor manufacturers will continue to represent a significant
percentage of PMT's product sales through at least 1996. During the year ended
December 31, 1995, sales to Alcan-Tech, Canon Sales and NEC Anelva in Japan,
and to LG Semicon and Hyundai in Korea, accounted for 25% and 18% of PMT's
total revenue, respectively, for that period. During the ten months ended
December 31, 1994, sales to Canon Sales and NEC Anelva in Japan, and to
Samsung and Hyundai in Korea, accounted for 31% and 32% of PMT's total
revenue, respectively, for that period. During the year ended February 28,
1994, sales to Alcan-Tech and NEC Anelva in Japan accounted for 44% of PMT's
total revenue for that period. There were no sales in Korea during the year
ended February 28, 1994. PMT's operating results could be materially adversely
affected by any loss of business from the cancellation of orders by or
decreases in the prices of products sold to these or other customers located
in Japan and Korea. See "Risk Factors--Increased International Exposure" and
Note 1 of Notes to Consolidated Financial Statements.
 
 Marketing, Sales and Customer Support
 
  PMT's long range goal is to market its products and services directly to all
end use customers to the extent it is efficient and cost effective. In the
current stage of PMT's growth, it is not efficient or cost effective to market
products and services through a direct sales force in all regions.
Consequently, PMT has established multiple sales channels to market products
and services to match PMT's efforts in each region. PMT currently markets
 
                                      62
<PAGE>
 
and sells its products primarily through three separate sales channels: direct
sales, distributor arrangements and OEM agreements. In selected regions and
countries, PMT uses a combination of direct sales, distributor arrangements,
OEM agreements and sales representatives.
 
  In the United States, PMT markets and sells its products principally through
its direct sales organization. In Korea, PMT markets and sells its products
direct through the sales staff of its wholly owned subsidiary, Plasma &
Materials Technologies (Korea) Co., Ltd. The Korean market is served by a
direct sales group in order to meet Korean semiconductor manufacturers'
requirements of having direct local representation for sales, customer support
and spare parts.
 
  PMT currently believes that the most efficient strategy for penetrating the
Japanese market is to have a distribution agreement with a well established
and experienced sales organization. PMT has appointed Canon Sales as its
exclusive etch system distributor in Japan, and in July 1995 entered into a
definitive agreement for such appointment. Although management believes that
it maintains a good relationship with Canon Sales, there can be no assurance
that the relationship will continue.
 
  In addition, PMT has established relationships in Taiwan and Europe with
sales representatives and distributors that have significant experience in the
semiconductor industry and that provide a high level of visibility for PMT's
products and services. In Taiwan, PMT markets etch systems through a
distribution agreement with Techlink, and in Europe, PMT has entered into a
distribution agreement with Metron to market its etch systems.
 
  PMT maintains active OEM agreements in Japan and Europe. PMT currently sells
the MORI(TM) source to Leybold of Germany for incorporation into Leybold's
systems that are sold worldwide for etching large area, active matrix liquid
crystal displays. PMT sells its MORI(TM) source to NEC Anelva for
incorporation into NEC Anelva's systems for metal and oxide etching and that
are sold in the Japanese market, and to Canon Sales for incorporation into
Canon Sales' systems for photoresist stripping that are sold in the Japanese
and Korean markets.
 
  PMT believes that providing its customers with evaluation systems of its
equipment products is critical to its sales efforts. The ability to evaluate
PMT's plasma processing systems on a trial basis is expected by the
semiconductor manufacturing customers to whom PMT markets. Consequently, as
PMT expands its sales efforts, it believes that it will need to significantly
increase its inventory investment in evaluation systems. The failure or
inability of PMT to convert an evaluation system placed with a customer to a
final sale could have a material adverse effect on PMT.
 
  PMT believes that customer support is a key component in a customer's
decision in selecting a semiconductor equipment supplier. The ability to
provide a processing system with a high degree of reliability, low cost, high
yield, high uptime and high mean time between failure greatly influences a
customer's purchase decision. This requires experienced, responsive local
support with quality personnel and ready availability of spare parts. PMT
believes that a focused field support organization that works closely with its
customers provides invaluable feedback from customers with respect to system
cost effectiveness, and typically results in technical advances through
continuous design improvement. To further ensure customer satisfaction, PMT
also provides service and maintenance training as well as process application
training for its customers' personnel on a fee basis. PMT maintains an
extensive inventory of spare parts which allows PMT to provide overnight
delivery for many parts. PMT currently provides a one-year warranty on its
systems.
 
  All international sales of PMT's products are denominated in U.S. dollars in
order to reduce the risks associated with the fluctuation of foreign currency
exchange rates. All export sales must be licensed by the Office of Export
Administration of the U.S. Department of Commerce. Although PMT has
experienced no difficulty in obtaining these licenses, failure to obtain these
licenses in the future could have a material adverse effect on PMT's results
of operations.
 
                                      63
<PAGE>
 
 Research, Development and Engineering
 
  PMT believes that its future success will depend, in part, upon its ability
to continue to improve its systems and its process technologies and to develop
new technologies and systems which compete effectively on the basis of total
cost of ownership and performance. These technologies and systems will also
need to meet customer requirements and emerging industry standards.
Accordingly, PMT devotes a significant portion of its personnel and financial
resources to research and development programs and seeks to maintain close
relationships with its customers in order to remain responsive to their
product needs.
 
  As of June 30, 1996, PMT employed 45 professional and technical personnel in
research, development and engineering. These employees are organized in the
following departments: research and development, hardware engineering,
software engineering, customer specials engineering, systems engineering,
documentation and manufacturing engineering, and customer applications.
 
  The research and development group is responsible for identifying new
technology applications and developing processes to meet customer
requirements. Major research and development programs currently address
polysilicon and integrated stack etch applications, metal etch applications,
including aluminum, and oxide etch applications. Additionally, the group is
overseeing the application of MORI(TM) technology to CVD applications.
 
  The engineering group is responsible for the conceptual design of PMT's
products, selection or design of components and subassemblies, and integration
of the system into a product that effectively meets customer needs. PMT has
developed both its PINNACLE 8000(R) and PINNACLE 8000R(TM) cluster tool
platforms utilizing the SEMI MESC cluster tool architecture standard. In
addition, PMT has developed MACSE(TM), its own proprietary software, to
control its products and to provide the automation, operator and facility
interfaces required by the customer.
 
  The customer applications group is responsible for demonstrating the
capability of PMT's products to meet specific customer process requirements.
PMT currently maintains two clean rooms and two development labs to support
process development and customer demonstrations.
 
  PMT's research, development and engineering expenses were $4.6 million and
$3.6 million for the year ended December 31, 1995 and the ten months ended
December 31, 1994, respectively, and represented 22% and 41% of total revenue
for these two periods, respectively.
 
  In addition to PMT's direct research, development and engineering expenses,
significant expenditures in research, development and engineering have been
made by Leybold, Canon Sales and NEC Anelva, with whom PMT has entered into
OEM agreements. These arrangements provide PMT with expanded resources and
knowledge to broaden the use of PMT's MORI(TM) plasma technology in the etch,
strip, CVD and flat panel markets. No information on the amount of these
expenditures has been disclosed to PMT; however, PMT believes that the total
exceeds PMT's direct expenditures for the same applications research over the
same periods identified above.
 
  Although PMT believes that it has allocated sufficient resources to its
research, development and engineering efforts, the success of new system
introductions is dependent on a number of factors, including timely completion
of new system designs and market acceptance. There can be no assurance that
PMT will be able to improve its existing systems and process technologies or
develop new technologies or systems. In addition, PMT may incur substantial
unanticipated costs to establish the functionality and reliability of its
future product introductions early in the product's life cycle.
 
 Joint Development Arrangements
 
  PMT has recently entered into an agreement with NEC Anelva to jointly
develop a high density plasma dielectric CVD system. Pursuant to the
agreement, the two companies intend to jointly develop, market, and
 
                                      64
<PAGE>
 
manufacture such CVD system based upon PMT's MORI(TM) source. The parties
contemplate that, upon completion of this development, PMT will manufacture
the system utilizing its primary cluster tool platform, the PINNACLE
8000R(TM). NEC Anelva will have exclusive marketing rights in Japan, Taiwan
and the Asia Pacific region, and PMT will have exclusive marketing rights in
the U.S., Korea and Europe. In the event of a termination of PMT's
relationship with NEC Anelva, or the failure by the parties to successfully
develop the CVD system, PMT's ability to penetrate the HDP dielectric CVD
market could be adversely affected.
 
  On March 29, 1996, PMT entered into a number of agreements with PMT CVD
Partners, L.P. (the "CVD Partnership") and the limited partners thereof (the
"Limited Partners"). The CVD Partnership was sponsored by PMT to fund research
and development costs and expenses relating to CVD technology and applications
using MORI(TM) source technology. An aggregate of approximately $5,350,000 was
invested by third parties in the CVD Partnership to fund such research and
development efforts, which are being performed by PMT under an agreement with
the CVD Partnership.
 
  PMT is paid for such services in an amount equal to its actual direct costs,
as defined, plus a stated percentage of such costs. During the six months
ended June 30, 1996, the amount of such research and development payments to
PMT by the CVD Partnership applications was approximately $849,000. PMT will
be obligated to pay stated royalties to the CVD Partnership on sales of
developed CVD products, and the royalty percentage will vary based on the
geographic location of the sale. There is no provision for royalty payments to
the CVD Partnership in fiscal 1996. PMT has been granted an exclusive option
to purchase all of the Limited Partners' interest in the CVD Partnership,
based on an established purchase price formula. PMT may exercise such option
at its sole discretion.
 
  PMT, NEC Anelva and the CVD Partnership have agreed that the CVD Partnership
(as assignee of PMT) will perform, through PMT as its contractor, all of PMT's
obligations under the NEC Anelva joint development agreement.
 
  PMT and LG Semicon have agreed to jointly develop an oxide etch process
utilizing PMT's PINNACLE 8000R(TM) cluster tool. PMT's wholly-owned Korean
subsidiary, Plasma & Materials Technologies (Korea) Co., Ltd., will manage the
process development work, which will be conducted at LG Semicon's Cheong-Ju
research and development facility in South Korea and at PMT's headquarters in
California. PMT believes that this joint development project will help PMT's
PINNACLE 8000R(TM) system achieve acceptance in the oxide etch market.
Although management believes that it maintains a good relationship with LG
Semicon, there can be no assurance that the relationship will remain positive,
or that the joint development project will be successfully completed. In the
event of a termination of PMT's agreement with LG Semicon, or the failure by
the parties to successfully develop an oxide etch process based on PMT's
PINNACLE 8000R(TM) cluster tool, PMT's ability to penetrate the oxide etch
market would be adversely affected.
 
 Manufacturing
 
  PMT's manufacturing operations are located in Chatsworth, California, and
consist of materials planning and procurement, assembly, system integration
and final test. PMT employs a just-in-time manufacturing strategy coupled with
the outsourcing of components and subassemblies from outside suppliers.
 
  PMT's modular product line, which is designed around the SEMI MESC industry
standard, enables PMT to use a large number of components and subassemblies
which are common not only to PMT's product line but also to systems
manufactured by other companies in the industry, both competitive and non-
competitive. Examples of subassemblies which are common to products
manufactured by other companies include the robotics, wafer aligner and vacuum
cassette elevators obtained from Brooks Automation in Massachusetts, and RF
power supplies obtained from RF Power Products in New Jersey. Examples of
subassemblies obtained from outside suppliers and that are unique to PMT's
systems products include gas box assemblies and fabricated vacuum chambers.
 
                                      65
<PAGE>
 
  PMT relies on outside suppliers to manufacture substantially all of the
components and subassemblies used in its plasma processing systems. Certain of
these are obtained from a sole supplier or a limited group of suppliers. For
example, the wafer cassette elevator load locks used in PMT's APEX 7000(R),
PINNACLE 8000(R) and PINNACLE 8000R(TM) plasma processing systems are sole
sourced from Brooks Automation. PMT's reliance on outside suppliers generally,
and a sole or limited group of suppliers in particular, involves several
risks, including a potential inability to obtain an adequate supply of
required components, as well as reduced control over pricing and timely
delivery of components. Because the manufacture of certain of these components
and subassemblies is a complex process and can require long lead times, there
can be no assurance that delays or shortages caused by suppliers will not
occur. Any inability to obtain adequate deliveries or any other circumstance
that would require PMT to seek alternate sources of supply or to manufacture
such components internally could delay PMT's ability to ship its systems and
could have a material adverse effect on PMT.
 
  PMT is subject to a variety of federal, state and local laws, rules and
regulations relating to the use, storage, discharge and disposal of hazardous
chemicals and gases used during its customer demonstrations and in research
and development activities. Public attention has increasingly been focused on
the environmental impact of operations which use hazardous materials. Failure
to comply with present or future regulations could result in substantial
liability to PMT, suspension or cessation of PMT's operations, restrictions on
PMT's ability to expand at its present locations, or requirements for the
acquisition of significant equipment or other significant expense. To date,
compliance with environmental rules and regulations has not had a material
effect on PMT's operations. At the present time, PMT believes that it is in
material compliance with all applicable environmental rules and regulations.
 
 Competition
 
  The markets served by PMT's products are highly competitive and subject to
rapid technological change. Significant competitive factors include system
performance, cost of ownership (which is dependent upon yield, throughput and
reliability), size of installed base, depth and breadth of product line and
customer support.
 
  PMT faces significant competition from various suppliers of systems that
utilize alternative technologies, including other manufacturers of high
density plasma (HDP) systems. In the etch market, PMT faces competition from
suppliers of reactive ion etch (RIE) systems, including Applied Materials, Lam
Research and Tokyo Electron. PMT's MORI(TM) based etch systems also face
competition from inductively coupled plasma (ICP) based etch systems marketed
by Applied Materials and Lam Research (and the Omega(TM) product of
Electrotech), as well as the electron cyclotron resonance (ECR) based etch
system marketed by Hitachi. In the HDP CVD market, PMT's primary competitors
are Applied Materials, Novellus and Lam Research. PMT's MORI(TM) source faces
competition from competitors that manufacture and market sources that utilize
various alternative technologies, including RIE, ICP and ECR based plasma
sources.
 
  All of PMT's primary competitors are substantially larger companies with
broader product lines, and have well established reputations in the etch and
CVD markets, longer operating histories, greater experience with high volume
manufacturing, broader name recognition, substantially larger customer bases,
and substantially greater financial, technical, manufacturing and marketing
resources than PMT. PMT also faces potential competition from new entrants in
the market, including established manufacturers in other segments of the
semiconductor capital equipment market, who may decide to diversify into PMT's
market segment. There can be no assurance that PMT's competitors will not
develop enhancements to or future generations of competitive products that
will offer price and performance features that are superior to those offered
by PMT's systems.
 
 Intellectual Property
 
  PMT relies on a variety of types of intellectual property protection to
protect its proprietary technology, including patent, copyright, trademark and
trade secret laws, non-disclosure agreements, and other intellectual property
protection methods. Although PMT believes that its patents and trademarks may
have value, PMT believes that its future success will also depend on the
innovation, technical expertise and marketing abilities of
 
                                      66
<PAGE>
 
its personnel. PMT currently holds five patents in the United States, has one
patent application pending in South Korea, has two patent applications pending
in each of Japan and Europe, and intends to file additional patent
applications as appropriate. PMT's patents and patent applications relate to
PMT's MORI(TM) plasma source. PMT also holds a copyright on its MACSE(TM)
proprietary software. In addition, PMT has six trademarks that are registered
with the United States patent and trademark office, including PMT(R), APEX
7000(R), PINNACLE 8000(R) and PINNACLE 8000R(TM).
 
  There can be no assurance that patents will be issued on the pending
applications or that competitors will not be able to legitimately ascertain
proprietary information embedded in PMT's products which is not covered by
patent or copyright. In such case, PMT may be precluded from preventing the
competitor from making use of such information. In addition, should PMT wish
to assert its patent rights against a particular competitor's product, there
can be no assurance that any claim in a PMT patent will be sufficiently broad
nor, if sufficiently broad, any assurance that a PMT patent will not be
challenged, invalidated or circumvented, or that PMT will have sufficient
resources to prosecute its rights. PMT intends to vigorously protect and
defend its patents, trademarks and trade secrets.
 
  There are no pending lawsuits against PMT regarding infringement of any
existing patents or other intellectual property rights or any unresolved claim
where PMT has received notice that it is infringing intellectual property
rights of others. There can be no assurance, however, that such infringement
claims will not be asserted in the future nor can there be any assurance, if
such claims are made, that PMT will be able to defend against such claims
successfully or, if necessary, obtain licenses on reasonable terms. In
addition, PMT believes that litigation in its industry over patent rights has
been increasing in recent years.
 
  PMT's involvement in any patent dispute or other intellectual property
dispute or in any action to protect trade secrets and know-how, even if
successful, could have a material adverse effect on PMT and its business.
Adverse determinations in any such action could subject PMT to significant
liabilities, require PMT to seek licenses from third parties, which might not
be available, and possibly prevent PMT from manufacturing and selling its
products, any of which could have a material adverse effect on PMT and its
business.
 
 Backlog
 
  As of August 31, 1996, PMT's backlog was approximately $4.0 million,
compared to $8.7 million at December 31, 1995. PMT's backlog at June 30, 1996
consisted primarily of orders for its PINNACLE 8000R(TM) systems.
Substantially all of the orders constituting backlog of PMT as of August 31,
1996 have been or will be shipped during PMT's fiscal quarter ending September
30, 1996. PMT's product sales for current periods will depend on the shipment
of products with respect to existing orders as well as the shipment of
products relating to the receipt of additional orders in that period.
 
  PMT includes in its backlog all purchase orders that provide for delivery
within twelve months. PMT's business is characterized by large purchase
contracts for standard products with related customized options. All orders
are subject to cancellation or delay by the customer with limited or no
penalty. Because of possible changes in delivery schedules and cancellations
of orders, PMT's backlog at any particular date is not necessarily
representative of actual sales for any succeeding periods.
 
 Employees
 
  At June 30, 1996, PMT had 144 regular employees, including 45 engaged in
research, development and engineering, 7 in sales and marketing, 40 in
customer support, 34 in manufacturing, and 18 in general administration and
finance. Following the Acquisition, PMT will oversee a significant number of
employees employed by Electrotech. Additionally, PMT intends to hire
additional personnel for its operations in California during the next 12
months in all of these areas.
 
  PMT believes its future success will depend in large part on its ability to
attract and retain highly skilled employees, particularly those highly skilled
design, process and test engineers involved in the manufacture of existing
systems and the development of new systems and processes. The competition for
such personnel is
 
                                      67
<PAGE>
 
intense. PMT faces the task of quickly identifying, recruiting, training and
integrating new employees. There can be no assurances that PMT will be
successful in doing so or, if successful, in retaining such employees.
 
  None of the employees of PMT are covered by a collective bargaining
agreement, and PMT has not entered into employment agreements with any of its
employees, although PMT intends to enter into a three year employment
agreement with Mr. Wheeler on consummation of the Acquisition. See "Proposal
No. 1--Terms of the Acquisition and Related Transactions--Conditions to the
Acquisition" and "--Related Agreements." PMT considers its relationships with
its employees to be good.
 
 Properties
 
  PMT currently leases two buildings that comprise a total of 54,000 square
feet in Chatsworth, California. PMT's 34,000 square foot corporate
headquarters building houses senior management, sales, marketing, research and
development, customer applications, engineering, and customer support
functions. The 20,000 square foot operations building houses all of PMT's
manufacturing operations, including materials planning, purchasing, shipping
and receiving, stockroom, assembly and test, as well as sales order entry,
finance and human resources. Current leases on both buildings expire on
December 31, 1996. PMT also leases on a month to month basis an office in
Seoul, Korea for sales and customer support. PMT may seek to expand beyond the
capacity of its current facilities and may seek additional space for all or
various portions of operations. In such case, management expects that PMT will
find acceptable space at competitive costs.
 
 Legal Proceedings
 
  In the ordinary course of its business, PMT may be involved in legal
proceedings from time to time. As of the date hereof, there are no material
legal proceedings pending against PMT.
 
BUSINESS OF ELECTROTECH
 
 Introduction
 
  Electrotech develops, manufactures, markets and services semiconductor
fabrication equipment for the worldwide semiconductor manufacturing industry.
Electrotech's proprietary products are targeted at three primary areas of
semiconductor manufacturing: PVD, CVD and etch. Electrotech's new leading-edge
products include the Sigma sputtering system for PVD, with the optional
Forcefill(TM) module, and the Planar 200 Flowfill(TM) system for inter-metal
dielectric CVD. Forcefill(TM) technology allows manufacturers to eliminate the
use of multi-step CVD tungsten-plug based metallization processes and to
utilize an entirely aluminum-based PVD multi-level metal scheme in sub-0.5
micron IC manufacturing. Electrotech's new CVD process technology,
Flowfill(TM), forms high quality silicon dioxide layers which possess the
properties of both gap fill and planarization. Electrotech also offers
products for the etch market, including its Omega(TM) ICP system.
 
  Electrotech utilizes a fully integrated manufacturing operation and sells
its products directly through local area sales support offices in the United
States and Europe, through a distributor in Japan and distributors or agents
in the rest of the world.
 
  Electrotech is a privately held company based in the United Kingdom, and was
founded in 1968 by a group of scientists formerly employed in the European
research division of ITT.
 
 Technologies and Products
 
  Electrotech research teams have developed two proprietary processes which
address major issues in the fabrication of the next generation of
semiconductor devices: Forcefill(TM) addresses the problem of introducing
interconnect wires into very small holes as the critical dimensions of ICs
become smaller, and Flowfill(TM) addresses the subsequent problem of
insulating the resulting closely-packed interconnect wiring. The Forcefill(TM)
and Flowfill(TM) projects are currently at the stage of customer review and
evaluation; however, considerable efforts are being applied by Electrotech to
attain product functionality and reliability levels acceptable to
Electrotech's target markets.
 
                                      68
<PAGE>
 
  Electrotech offers its customers products that address three major steps in
the semiconductor manufacturing process: the deposition of metallic aluminum
layers (Sigma), the deposition of insulating dielectric layers (Planar and
Delta) and the dry plasma etching of these deposited layers (Omega(TM)). In
order to leverage Electrotech's current products into the manufacturing of
next generation semiconductors, Electrotech's customers may purchase
Electrotech's Sigma and Planar deposition systems and subsequently buy
Forcefill(TM) and Flowfill(TM) add-on modules, which utilize Electrotech's
advanced proprietary technologies.
 
 Physical Vapor Deposition
 
  SIGMA
 
  Layers of metal alloys can be deposited by Electrotech's Sigma product line,
a sputtering machine with multiple process chambers. This product deposits a
very thin uniform layer of interconnect metal on the whole surface of the
semiconductor wafer. Subsequent lithography and etching turns this layer into
an intricate pattern of interconnect wiring on the many individual
semiconductor devices, each a complex and integrated functioning circuit.
 
  The Sigma is designed to be one of the cleanest PVD systems on the market,
with particular application in multi-layer metallization. Electrotech's
strategy is to offer semiconductor manufacturers who are currently using 0.8
micron to 1.0 micron design rules a way to avoid the adoption of CVD tungsten,
a relatively difficult, dirty and expensive process. Electrotech offers system
configurations which bridge the gap from non-hole-fill technology, at
approximately 1.0 micron, to the adoption of Electrotech's Forcefill(TM)
technology onto the Sigma platform, which is capable of filling holes smaller
than 0.25 micron. The selling price for the Sigma system ranges from
approximately $1.5 million to approximately $2.5 million, depending on the
configuration of the system.
 
  SIGMA FORCEFILL(TM)
 
  The Sigma Forcefill(TM) system is being developed to extend Electrotech's
standard Sigma metallization product capability into the sub-0.5 micron
market. The Forcefill(TM) technology is used with traditional aluminum
techniques and eliminates the relatively complicated and difficult use of
tungsten. The process can be carried out on a standard Sigma series system
with an attached Forcefill(TM) module, which involves depositing a layer of
aluminum such that it forms a bridge over the holes. When adequate bridging is
achieved the wafer is transferred under vacuum to the Forcefill(TM) module
where the aluminum is heated and forced under very high pressure into the
hole, thus achieving void-free fill. Forcefill(TM) allows manufacturers to
eliminate the use of CVD tungsten and to utilize an entirely aluminum-based
multi-level metal scheme. DRAM and logic applications are both target markets
for Forcefill(TM), since the cost saving per layer is substantial, and the
interconnect speed is improved.
 
  Electrotech management believes that the Forcefill(TM) process has a number
of advantages when compared to the commonly used alternative technologies of
tungsten-plug with CMP and aluminum reflow. This is believed to be due to a
number of factors:
 
  . Fewer defects. Using tungsten-plug with CMP is a relatively dirty process
    that often results in the accumulation of particles in the wafer
    processing module leading to defective wafers and preventative
    maintenance downtime for cleaning. The Forcefill(TM) module provides for
    a cleaner production process, which leads to higher yields.
 
  . Improved process latitude. Tungsten-plug and aluminum reflow both require
    a greater degree of control than Forcefill(TM), which is more tolerant of
    variations in device features that result from prior manufacturing steps,
    leading to higher yields.
 
  . Longer device lifetime. Under test conditions, Forcefill(TM) has shown
    electromigration resistance approximately 30 times greater than tungsten-
    plug/aluminum when measured on a state of the art multilevel device.
 
                                      69
<PAGE>
 
  . Reduced metal thickness. Aluminum reflow requires a thick metal layer,
    typically at least 1 micron. The Forcefill(TM) process only requires the
    applied metal thickness to be greater than the contact or via hole
    diameter. Thin metal layers result in reduced capacitance loss and
    greater ease of planarization.
 
  . Compatibility with stacked vias. The Forcefill(TM) process has made
    stacked vias possible without requiring metal CMP, as would be needed in
    a tungsten-plug scheme.
 
The average selling price of the Sigma Forcefill(TM) system ranges from
approximately $3.5 million to approximately $4.0 million, depending on the
configuration of the system.
 
 Chemical Vapor Deposition
 
  DELTA 201
 
  Electrotech's Delta 201 is a versatile, single-chamber production system for
producing films, including silicon dioxide or silicon nitride. The films
deposited by this system are used to insulate the interconnect wiring of a
semiconductor wafer. It is a relatively low-cost system and its small
dimensions make it attractive to customers, who are often short of cleanroom
space. The Delta 201 also addresses the gallium arsenide semiconductor market
and incorporates a wafer handling mechanism that is suited to handle fragile
and high-cost gallium arsenide wafers. The average selling price for the Delta
201 system is approximately $600,000.
 
  PLANAR 200 FLOWFILL(TM)
 
  Flowfill(TM) technology has been developed by Electrotech in order to meet
the needs of the planarized intermetal dielectric market. The problem of
finding a suitable insulating material to protect the microscopic wiring in a
chip has produced a number of materials with various undesirable
characteristics. The most common insulating material is silicon dioxide,
which, when deposited by conventional techniques, is unable to fill the
increasingly small gap spacing required by next generation ICs. Electrotech
has developed a new CVD process technology, Flowfill(TM), to form high quality
silicon dioxide layers which possess the properties of both gap fill and
planarization. In the Planar 200 Flowfill(TM) multi-chambered cluster system,
the advanced planarization layer consists of three films which are deposited
sequentially. The plasma CVD films are deposited in one module and the CVD
planarizing flow layer is deposited in the Flowfill(TM) module with no vacuum
breaks between the process steps. The flow layer has the ability to fill sub-
micron features less than 0.2 micron wide, with a 5 to 1 height to width
ratio, and achieve typical planarization of 80% for gaps up to 20 microns.
 
  Alternative technologies to Electrotech's Flowfill(TM) system include SOG
and HDP combined with CMP. SOG is deposited in single or multiple spins. This
technique is complex and slow due to the number of steps involved. In
addition, although each individual step may be clean, the combination can lead
to a high number of added particles, which can decrease yield. HDP gap fills a
wafer with silicon dioxide in one system, but the rough spots on the wafer
must be planarized using a CMP process in a second system.
 
  Electrotech management believes that the major advantages of Flowfill(TM),
when compared to competing technologies, can be summarized as follows:
 
  . Small gaps. Flowfill(TM) is capable of filling very small gaps (less than
    0.08 micron has been recorded).
 
  . Combined process. Flowfill(TM) both gap fills and planarizes
    simultaneously, eliminating the need for CMP on some devices. The
    combined process also results in a decrease in equipment costs,
    manufacturing time and defect levels, while increasing yields.
 
  . Lower moisture. Flowfill(TM) leaves very little moisture content in the
    film after final treatment and allows for low moisture reabsorbance. This
    should result in better device reliability.
 
  . Better quality. The quality of the Flowfill(TM) planarized layer has been
    demonstrated to be better than that of SOG.
 
 
                                      70
<PAGE>
 
  For a number of reasons, Electrotech's initial shipments of the Planar 200
Flowfill(TM) have targeted the DRAM market. First, due to the competitive
nature of the DRAM market, cost is a primary concern to DRAM manufacturers.
Certain DRAM manufacturers have indicated that Flowfill(TM) will offer
significant cost advantages for next generation DRAMs relative to both the SOG
and HDP processes. Second, due to the circuit designs of a DRAM, the maximum
distance between metal lines is 80 to 100 microns, Flowfill(TM) provides a
high level of planarity for gaps of this size.
 
  The selling price for the Planar 200 Flowfill(TM) system ranges from
approximately $1.4 million to approximately $2.5 million, depending on the
configuration of the system.
 
 Etch
 
  OMEGA(TM) 201-2
 
  Electrotech's etch product, the Omega(TM) 201-2 metal etch system,
integrates the field-proven 200-series hardware as used on other current
Electrotech products with Electrotech's patented Inductively Coupled Plasma
(ICP) technology. Although mainly targeted at metal interconnect, the
technology is also able to address oxide and polysilicon etch and is
compatible with all etch applications. Most competitors, which include PMT,
also use a high ion density, low pressure plasma source.
 
  The Omega(TM) 201-2 metal etch system has been designed to address the
special requirements of metal etch while minimizing the space utilized in the
clean room. The system has a passivation unit which minimizes post-etch
corrosion by combining the use of a downstream plasma with radiant heating of
the wafer backside to maximize photoresist strip rates and drive off
involatile chlorine-containing materials. The Omega(TM) 201-2 also has a wafer
temperature control system which ensures that etch residues are minimized and
often eliminates the need to harden the photoresist using a deep UV process.
 
  Electrotech management believes that its Omega(TM) etch systems have
advantages over competitive products, including: (i) process performance--
simple chemistries giving rise to better process control; (ii) simple hardware
platform; (iii) long electrostatic chuck lifetime; (iv) lower capital cost;
and (v) low operating costs. The price for Electrotech's Omega(TM) etch system
ranges from approximately $700,000 to approximately $1,400,000, depending on
the configuration of the system.

  Electrotech sells its systems to semiconductor manufacturers located
throughout Europe, the United States and Japan. The following is a list of
selected customers who have purchased Electrotech products, some of which have
evaluation systems using Electrotech's Forcefill(TM) or Flowfill(TM)
technologies:

</TABLE>
 
 Marketing, Sales and Customer Service
 
  Electrotech revenues derive primarily from the sale of capital equipment and
related consumable components. Sales outside of the United Kingdom accounted
for over 80% of Electrotech's revenues in fiscal 1995. Electrotech has sales
and marketing offices located in the United Kingdom, the United States, Europe
and Asia to enable sales and service personnel to provide dedicated worldwide
support to new and existing
 
                                      71
<PAGE>
 
customers. Electrotech also established its first sales distributor in Japan
in 1983. Since that time, Electrotech's presence in the Asia/Pacific region
has been further expanded by the appointment of agents for Hong Kong, South
Korea, Taiwan, Singapore and China. This geographical expansion has resulted
in increased flexibility and responsiveness to customer needs.
 
  Electrotech believes that high quality customer support, customer training
and field consultation are key components in a customer's decision in
selecting a semiconductor equipment supplier. In that regard, Electrotech has
made a substantial investment in customer support and customer training and
presently has approximately 150 employees in the marketing, sales and customer
service areas.
 
 Research, Development and Engineering
 
  Since its formation, intensive, ongoing research has enabled Electrotech to
achieve leading-edge technological advancements in the field of semiconductor
manufacturing equipment. Electrotech has dedicated permanent research teams to
each of PVD, CVD and etch semiconductor manufacturing processes. As of
June 30, 1996, Electrotech employed 104 professional and technical personnel
in research and development. For the year ended June 30, 1996, Electrotech's
research, development and engineering expenses were $10.3 million, compared to
$6.9 million for the year ended June 30, 1995.
 
 Manufacturing
 
  In order to maintain close control of its manufacturing processes,
Electrotech has adopted a policy of vertical integration. This approach has
enabled the organization to ensure quality control and reduce dependence on
third party suppliers. Electrotech operates facilities at which it
manufactures sheet metal components, machine parts and electronic assemblies
and assembles finished products. This strategy has provided benefits to
Electrotech, including supplier independence, tighter cost control of
components and sub-assemblies, and controllable delivery performance.
 
  Due to recent growth in Electrotech's sales and its development of new
products, Electrotech's existing facilities have reached capacity. Electrotech
has leased a 102,000 square foot facility into which it moved certain of its
corporate headquarters sales, customer support and financing operation in
January 1996. Approximately 20,000 square feet of the facility are currently
in use, with the remainder being built out with a view to full occupancy in
early 1997. See "--Properties."
 
 Competition
 
  The markets served by Electrotech's products are highly competitive and
subject to rapid technological change. Significant competitive factors include
system performance, cost of ownership (which is dependent upon yield,
throughput and reliability), size of installed base, depth and breadth of
product line and customer support.
 
  Electrotech faces significant competition from various suppliers of systems
that utilize alternative technologies. In the PVD market, Electrotech's
Forcefill(TM) technology faces competition from suppliers of aluminum and
tungsten-plug PVD systems, such as Applied Materials, and a number of other
competitors, including NEC Anelva, MRC, Novellus, Varian and Ulvac.
Electrotech's Flowfill(TM) technology faces competition from other CVD
manufacturers including Applied Materials, Lam Research, Novellus and Watkins-
Johnson. In the etch market, Electrotech faces competition from suppliers of
plasma etch systems, including Applied Materials, Hitachi, Lam Research, PMT
and Tokyo Electron.
 
  Most of Electrotech's competitors are substantially larger companies with
broad product lines, and have well established reputations in the PVD, CVD,
SOG and etch markets, greater experience with high volume manufacturing,
broader name recognition, substantially larger customer bases and
substantially greater financial, technical, manufacturing and marketing
resources than Electrotech. Electrotech also faces potential competition from
new entrants in the market, including established manufacturers in other
segments of the semiconductor capital equipment market, who may decide to
diversify into Electrotech's market segments. There can be no
 
                                      72
<PAGE>
 
assurance that Electrotech's competitors will not develop enhancements to or
future generations of competitive products that will offer price and
performance features that are superior to those offered by Electrotech's
systems.
 
 Intellectual Property
 
  Electrotech relies on a variety of types of intellectual property protection
to protect its proprietary technology, including patent, copyright, trademark
and trade secret laws, non-disclosure agreements, and other intellectual
property protection methods. Although Electrotech believes that its patents
and trademarks may have value, Electrotech believes that its future success
will also depend on the innovation, technical expertise and marketing
abilities of its personnel. Electrotech currently holds two patents in the
United Kingdom, five patents in the United States, two patents in Taiwan, and
one patent in each of Germany, France, Italy and the Netherlands. Electrotech
has approximately 49 patent applications pending worldwide. Electrotech's
patents and patent applications pending are all in the field of semiconductor
manufacture and are predominantly concerned with inductively coupled plasma
etching (ICP), deposition of dielectric layers by plasma and thermal means and
in particular the global planarization by a dielectric film (Flowfill(TM)) and
the process of filling semiconductor contact holes by deformation of
interconnect metal by high pressure (Forcefill(TM)) and the equipment related
to these processes. Electrotech uses a number of trademarks that are
registered or applied for registration in certain countries, including the
following: Electrotech(TM), Forcefill(TM) and Flowfill(TM).
 
  Electrotech is currently defending a challenge to its ICP patent in Europe.
Due to the new material presented as part of that challenge, Electrotech's
related patent in the United States will be reexamined. In addition,
Electrotech is opposing an issued German patent held by a competitor which
relates to a process similar to Forcefill(TM). Electrotech's advisers believe
this patent is too broadly worded and as presently worded there is some
possibility that an infringement by Electrotech might be alleged. There can be
no assurance as to the outcome of any of these proceedings.
 
  There can be no assurance that additional patents will be issued on
Electrotech's pending applications or that competitors will not be able to
legitimately ascertain proprietary information embedded in Electrotech's
products which is not covered by patent or copyright. In such case,
Electrotech may be precluded from preventing the competitor from making use of
such information. In addition, should Electrotech wish to assert its patent
rights against a particular competitor's product, there can be no assurance
that any claim in an Electrotech patent will be sufficiently broad nor, if
sufficiently broad, any assurance that such patent will not be challenged,
invalidated or circumvented, or that Electrotech will have sufficient
resources to prosecute its rights. Electrotech's policy is to vigorously
protect and defend its patents, trademarks and trade secrets.
 
  Electrotech's involvement in any patent dispute or other intellectual
property dispute or in any action to protect trade secrets and know-how, even
if successful, could have a material adverse effect on Electrotech and its
business. Adverse determinations in any such action could subject Electrotech
to significant liabilities, require Electrotech to seek licenses from third
parties, which might not be available, and possibly prevent Electrotech from
manufacturing and selling its products, any of which could materially and
adversely affect Electrotech and its business.
 
 Backlog
 
  At August 31, 1996, Electrotech's backlog was $19.5 million. Electrotech's
backlog at August 31, 1996 consisted primarily of orders for 11 systems.
 
  Electrotech includes in its backlog all purchase orders that provide for
delivery within twelve months. Electrotech's business is characterized by
large purchase contracts for standard products with related customized
options. All orders are subject to cancellation or delay by the customer with
limited or no penalty. Because of possible changes in delivery schedules and
cancellations of orders, Electrotech's backlog at any particular date is not
necessarily representative of actual sales for any succeeding periods.

  As of September 9, 1996, there were 107 shareholders of record of Common
Stock.
 
  PMT has not declared or paid cash dividends to its shareholders. PMT
anticipates that all of its earnings in the near future will be retained for
the development and expansion of its business and, therefore, does not
anticipate paying dividends on its Common Stock in the foreseeable future.
Declaration of dividends on the Common Stock will depend, among other things,
upon levels of indebtedness, future earnings, the operating and financial
condition of PMT, its capital requirements and general business conditions.
The agreements governing PMT's indebtedness contain provisions which prohibit
PMT from paying dividends on its Common Stock. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations of PMT--
Liquidity and Capital Resources."
 
  On July 17, 1996, the last trading day prior to the first public
announcement by PMT of the proposed Acquisition, the closing price of Common
Stock reported on Nasdaq was $12.625 per share. On September 9, 1996, the
closing price of Common Stock as reported on Nasdaq was $11.625 per share.
 
  There is no public market for the Electrotech shares. As of September 9,
1996, there were five stockholders of record of Electrotech.

  PMT currently has no employment contracts with any of the Named Executive
Officers. However, upon the dissolution or liquidation of PMT or upon any
reorganization, merger or consolidation in which PMT does not survive, PMT's
1991 Stock Option Plan, and each outstanding option granted thereunder shall
terminate, provided that each optionee to whom no substitute option has been
tendered by the surviving corporation in any such transaction shall have the
right to exercise in whole or in part any unexpired option or options issued
to him or her, without regard to the vesting provisions thereof.
 
  Upon the effectiveness of the Acquisition (and as a condition to the
obligations of the Electrotech shareholders to consummate the Acquisition),
PMT will enter into an Employment Agreement with Nigel Wheeler pursuant to
which Mr. Wheeler will be employed by PMT as its President and Chief Operating
Officer for a three-year term. See "Proposal No. 1--Terms of the Acquisition
and Related Transactions--Related Agreements."
 
1991 STOCK OPTION PLAN
 
  PMT's 1991 Stock Option Plan (the "Option Plan") provides for the granting
of either incentive stock options or nonqualified stock options to specified
employees, directors, consultants and advisors of PMT. The Option Plan is
administered by the Compensation Committee of the Board of Directors.
 
  The exercise price of stock options granted under the Option Plan must be
equal to at least the fair market value of the stock subject to the option on
the date of the grant (or 110% with respect to holders of more than 10% of the
voting power of PMT's outstanding Common Stock). Options granted under the
Option Plan are non-transferable and generally expire thirty days after the
termination of an optionee's service to PMT. See "Proposal No. 3--Amendment of
PMT's 1991 Stock Option Plan" for further information regarding the Option
Plan.
 
STOCK OPTION GRANTS
 
  The following table sets forth each grant of stock options made during the

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Compensation Committee of the Board of Directors of PMT (the
"Compensation Committee") consisted of Messrs. Rollwagen, Jones and Robelen
during the fiscal year ended December 31, 1995. Mr. Robelen resigned as a
director of PMT and a member of the Compensation Committee, effective
April 24, 1996. Mr. Rollwagen resigned from the Compensation Committee,
effective April 24, 1996. Simultaneously with such resignations from the
Compensation Committee, the Board of Directors voted to reduce the number of
members of the Compensation Committee from three to two. On April 24, 1996,
Charles Thompson was appointed by the Board to fill the remaining vacancy on
the Compensation Committee.
 
  Other than Mr. Rollwagen, PMT's Chairman of the Board, none of these
individuals was at any time during the fiscal year ended December 31, 1995 or
at any other time an officer or employee of PMT. No executive officer of PMT
serves as a member of the Board or the Compensation Committee of any other
entity which has one or more executive officers serving as a member of PMT's
Board of Directors or Compensation Committee. See "Proposal No. 2--Election of
Directors--Meetings of the Board of Directors and Director Compensation"

  PMT believes the foregoing transactions were in its best interests and were
on terms no less favorable to PMT than could be obtained from unaffiliated
third parties.
 
  In May 1995, the Board of Directors of PMT granted to each of Messrs.
Marshall and Frye an option to purchase 10,000 shares of Common Stock at an
exercise price of $1.65 per share. These options vest in equal annual
increments over a five-year period following the date of grant.
 
  In June 1995, the Compensation Committee granted to Dr. Campbell and Messrs.
Marshall, LaValle and Frye options to purchase 96,666 shares, 20,000 shares,
20,000 shares and 20,000 shares of Common Stock, respectively, each at an
exercise price of $6.30 per share. The Committee provided that two-thirds of
the shares covered by these options would vest in equal annual increments over
a five-year period following their date of grant, and one-third of the shares
covered by each option would vest in their entirety only on the date which is
five years from the date of grant. However, the Board of Directors retained
the discretion to accelerate the vesting of these one-third portions based
upon the future performance of PMT. In January 1996, the Board voted to
accelerate the vesting of such portions of the options.
 
REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS OF PMT
 
  The Compensation Committee recommends to the Board of Directors general
compensation policies for the Company, oversees the Company's compensation
plans and specific compensation levels for executive officers, and administers
the Bonus Plan and the Option plan.
 
  The following is the Compensation Committee's report submitted to the Board
of Directors addressing the compensation of the Company's executive officers
for 1995.
 
COMPENSATION POLICY
 
  The Company's executive compensation policy is designed to establish an
appropriate relationship between executive pay and the Company's annual
performance, long term growth objectives and ability to attract and retain
qualified executive officers. The Compensation Committee addresses this
objective by integrating competitive annual base salaries with (a) bonuses
based on annual corporate performance and the achievement of individual
performance objectives, through the Bonus Plan, and (b) stock option grants
under the Option Plan. The Compensation Committee believes that cash
compensation in the form of salary and bonus provides
 
                                      80
<PAGE>
 
Company executives with appropriate immediate rewards for success in current
operations, while stock option grants promote management stock ownership and
thereby expand management's stake in the long-term performance and success of
the Company.
 
  For 1995, the Compensation Committee approved the base salaries of each of
the Company's executive officers. In determining such base salaries, the
Company relied primarily on a survey prepared by Radford Associates, a
division of the Alexander and Alexander Consulting Group, of salaries paid to
executive officers of semiconductor equipment companies and other high
technology companies with sales comparable to those of the Company. For 1995,
the Compensation Committee set the base salaries of the Company's executive
officers generally at the median level of the salaries reflected in the
Radford survey.
 
  In 1995, the executive officers of the Company, including the President and
Chief Executive Officer, as well as six other key employees of the Company,
were each granted options under the Option Plan. The number of options that
each executive officer or employee was granted was based primarily on the
executive's or employee's ability to influence the Company's long-term growth
and profitability. The vesting provisions of the options granted under the
1991 Option Plan are designed to encourage longevity of employment with the
Company.
 
COMPENSATION OF CHIEF EXECUTIVE OFFICER
 
  The Compensation Committee believes that Dr. Campbell, the Company's
President and Chief Executive Officer, provides valuable services to the
Company, and that his compensation should therefore be competitive with that
paid to executives at comparable semiconductor equipment companies. In
addition, the Compensation Committee believes that the compensation of the
President and Chief Executive Officer should be heavily influenced by Company
performance. Therefore, although there has necessarily been some subjectivity
in setting Dr. Campbell's salary, major elements of his compensation package
are directly tied to Company performance.
 
  For 1995, Dr. Campbell's salary remained at $160,000, an amount the
Compensation Committee deemed appropriate in light of the Company's stage of
growth and salaries paid to chief executive officers of other growth
technology companies.
 
INTERNAL REVENUE CODE SECTION 162(m)
 
  Under Section 162 of the Code, the amount of compensation paid to certain
executives that is deductible with respect to PMT's corporate taxes is limited
to $1,000,000 annually. It is the current policy of the Compensation Committee
to maximize, to the extent reasonably possible, PMT's ability to obtain a
corporate tax deduction for compensation paid to executive officers of PMT to
the extent consistent with the best interests of PMT and its shareholders.
 
  The foregoing report has been furnished by Messrs. Jones and Thompson.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
  Section 16(a) of the Exchange Act ("Section 16(a)"), requires PMT's directors
and certain of its officers, and persons who own more than 10% of a registered
class of PMT's equity securities (collectively, "Insiders"), to file reports of
ownership and changes in ownership with the Securities and Exchange Commission
(the "Commission"). Insiders are required by Commission regulations to furnish
PMT with copies of all Section 16(a) forms they file.
 
  Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5s were
required for those persons, PMT believes that its Insiders complied with all
applicable Section 16 filing requirements for 1995, with the exception of (i)
G. Bradford Jones and Brian D. Jacobs, directors of PMT who each filed a Form 5
in February 1996 to reflect each person's receipt of a stock option grant in
June 1995 prior to the Initial Public Offering and (ii) St. Paul, which filed a
Form 5 in February 1996 to reflect its indirect acquisition of the same stock
option grant attributed to Mr. Jacobs described above as a result of an
agreement between Mr. Jacobs and St. Paul whereby ownership of the Common Stock
underlying such stock option grant will be transferred to St. Paul upon
exercise of such option by Mr. Jacobs.

                     PROPOSAL NO. 2--ELECTION OF DIRECTORS
 
  PMT's Bylaws provide that the Board of Directors shall have six directors. A
Board of six is therefore to be elected at the Annual Meeting. Unless
otherwise instructed, the proxy holders will vote the proxies received by them
for PMT's six nominees. In the event that any nominee of PMT is unable or
declines to accept nomination of election, the proxies will be voted for any
nominee who shall be recommended by the present Board of Directors. Management
has no present knowledge that any of the persons named will be unavailable or
unwilling to serve. The terms of office for each person elected as a director
will continue until the next Annual Meeting of Shareholders or until such
director's successor has been elected and qualified.
 
  The six nominees who receive the greatest number of votes cast for the
election of those directorships shall become directors at the conclusion of
the tabulation of votes. Upon the request of any person entitled to vote, each
holder of Common Stock voting in the election of directors may cumulate such
holder's votes and give one candidate a number of votes equal to the number of
directors to be elected multiplied by the number of shares of Common Stock
held by such holder, or distribute such holder's votes on the same principle
among as many candidates as the holder may select, provided that votes cannot
be cast for more than six candidates. However, no shareholder shall be
entitled to cumulate votes for any candidate unless, pursuant to the Bylaws of
the Company, the candidate's name has been placed in nomination prior to the
voting.
 
                                      85

EXPANSION OF THE BOARD UPON CLOSING OF THE ACQUISITION
 
  It is a condition to the closing of the Acquisition that Christopher D.
Dobson and Nigel Wheeler shall each have been elected as members of the Board
of Directors of PMT (and additionally shall have been elected as the Vice
Chairman of the Board and the President and Chief Operating Officer,
respectively, of PMT). See "Proposal No. 1--The Acquisition--Terms of the
Acquisition and Related Transactions--Conditions to the Acquisition."
Accordingly, if the Acquisition is approved by the shareholders of PMT and is
consummated, immediately prior to the closing of the Acquisition the Board of
Directors of PMT intends to (1) adopt an amendment to the Bylaws of PMT
increasing the size of PMT's Board of Directors from six to eight directors
and (2) elect Messrs. Dobson and Wheeler as directors of PMT, to serve in such
capacity until the next Annual Meeting of Shareholders or until their
successors are duly elected and qualified.
 
  During the past five years, Mr. Dobson, age 60, has been the Group Chairman
of Electrotech, and Mr. Wheeler, age 46, has served as Director and Chief
Executive Officer of Electrotech.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  The Board of Directors has an Audit Committee and a Compensation Committee.
The Audit Committee, which was established in 1990, reviews the results and
scope of the audit and other services provided by PMT's independent auditors,
reviews and evaluates PMT's internal control functions, and monitors
transactions between PMT and its employees, officers and directors. The
Compensation Committee administers PMT's stock option and 401(k) plans and
designates compensation levels for officers and directors of PMT.
 
MEETINGS OF THE BOARD OF DIRECTORS AND DIRECTOR COMPENSATION
 
  During 1995 the Board of Directors held seven meetings and took various
actions by unanimous written consent. Each incumbent director attended at
least 75% of the aggregate of (i) the total number of meetings held by the
Board of Directors during 1995 and (ii) the total number of meetings held by
all committees of the Board of Directors on which he served during that
period.
 
  Each director is elected to hold office until the next annual meeting of
shareholders and until his respective successor is elected and qualified.
Except for Mr. Rollwagen, the Chairman of the Board, directors do not receive
salaries for services on the Board of Directors or on any Committees of the
Board of Directors. All outside directors may be reimbursed for certain out-
of-pocket expenses incurred in connection with attendance at Board and
committee meetings.
 
  In June 1995 Mr. Rollwagen agreed to increase his duties as the Chairman of
the Board of PMT to a half-time basis. In consideration therefor, PMT agreed
to pay Mr. Rollwagen an annual salary of $144,000, with an additional bonus
payable in the future at the Board's discretion, to pay Mr. Rollwagen's one-
time expenses of $15,000, and to pay Mr. Rollwagen's yearly expenses in an
amount up to $111,600 per year. In addition, in June 1995, the Compensation
Committee approved the grant to Mr. Rollwagen of options to purchase 73,333
shares of Common Stock at an exercise price of $6.30 per share. Mr.
Rollwagen's options vest in equal annual increments over a five-year period
following the grant date, except that the Board of Directors had the
discretion to accelerate the vesting of 6,667 of such options based upon the
future performance of PMT. In January 1996, the Board of Directors voted to
accelerate the vesting of such 6,667 options in accordance with the terms of
the grant.
 
  In addition, in June 1995 the Compensation Committee approved the grant to
each of Messrs. Jacobs and Jones of an option to purchase 8,333 shares of
PMT's Common Stock at an exercise price of $6.30 per share, which options
vests in equal annual increments over a five-year period following their date
of grant, June 2, 1995, subject to such individuals' continued service as
directors of PMT.
 
  In April 1996 the Board of Directors adopted a policy authorizing the grant
of options to purchase 12,500 shares of Common Stock to each director upon his
or her initial election to the Board of Directors. Such policy
 
                                      87
<PAGE>
 
further authorizes the grant of options to purchase 2,500 shares of Common
Stock to each director upon his or her reelection to such position at each
subsequent Annual Meeting of Shareholders. In April 1996 the Compensation
Committee, pursuant to such policy, granted options to purchase 12,500 shares
of Common Stock at an exercise price of $14.75 per share to each of Messrs.
Thompson and Mizuno upon their initial election to the Board of Directors. PMT
intends to grant to each incumbent director an option to purchase 2,500 shares
of Common Stock, at an exercise price equal to the fair market value of the
Common Stock at the date of grant, if and when such director is reelected at
any Annual Meeting.
 
           PROPOSAL NO. 3--AMENDMENT OF PMT'S 1991 STOCK OPTION PLAN
 
  At the Annual Meeting, the shareholders will be asked to approve an
amendment (the "Amendment") to the Company's 1991 Stock Option Plan (the
"Option Plan"). On April 24, 1996, the Board adopted an amendment, subject to
shareholder approval as described herein, increasing the number of shares of
Common Stock available for issuance upon the exercise of options granted under
the Option Plan from 900,000 to 1,300,000. Following the execution of the
Share Purchase Agreement, the Board adopted a further amendment to the Option
Plan to increase the number of shares of Common Stock available for issuance
upon the exercise of options thereunder to 2,400,000, subject to the closing
of the Acquisition. The Board adopted this further increase in light of (1)
the condition to the Acquisition, as set forth in the Share Purchase
Agreement, that on or prior to the closing of the Acquisition PMT shall have
granted under the Option Plan, to certain employees of Electrotech, options to
purchase an aggregate of approximately 800,000 shares of Common Stock and (2)
the substantially increased number of employees of the Company following the
Acquisition and the continuing need for additional available options to grant
to employees from time to time.
 
  These amendments to the Option Plan are referred to herein collectively as
the "Amendment," and therefore constitute a proposal to increase the number of
shares issuable upon the exercise of options under the Option Plan to a
minimum of 1,300,000 shares and, conditioned and effective only upon the
closing of the Acquisition, to 2,400,000 shares. The Option Plan and
information regarding options granted thereunder is summarized below, but
these descriptions are subject to and are qualified in their entirety by the
full text of the Option Plan as currently in effect which is attached as Annex
C to this Proxy Statement. The full text of the proposed Amendment is attached
as Annex D to this Proxy Statement.
 
  The purpose of the Amendment is to increase the number of shares of Common
Stock available for option grants which can serve as an incentive and to
encourage stock ownership by officers, directors, employees, consultants and
advisors of the Company or any of its subsidiaries. As of April 24, 1996, no
further shares of Common Stock were available for grants under the Option
Plan. On April 24 and July 11, 1996, options to purchase an aggregate of
77,718 shares of Common Stock were granted, subject to shareholder approval of
the Amendment. These option grants will not become effective unless the
Amendment is approved by the shareholders. The Board believes that increasing
the number of stock options available for grant under the Option Plan to
1,300,000 is advisable because such awards promote interest in the welfare of
the Company by allowing such persons to share in the success of the Company
and encouraging them to remain in the service of the Company. It also gives
the Company a means to attract qualified new employees. The further increase
in the number of stock options available for grant under the Option Plan to
2,400,000 upon the Acquisition is necessary in order to permit the grant of
options covering an aggregate of approximately 800,000 shares to employees of
Electrotech on or immediately prior to the Closing (which grant is a condition
to the obligations of the Electrotech Shareholders under the Share Purchase
Agreement) and to provide additional options for further incentives to
employees of the combined company following the Acquisition.
 
SUMMARY OF THE OPTION PLAN
 
  The Option Plan provides for the granting of options ("Options") to purchase
shares of Common Stock to key employees, directors, consultants and advisors
of the Company or any of its Subsidiaries, to be selected as set forth below.
A person who holds an Option is referred to therein as a "Participant." For
purposes of the
 
                                      88
<PAGE>
 
Option Plan, the term "Subsidiary" means any corporation, of which 50% or more
of the voting stock is owned by the Company or by a Subsidiary (as so defined)
of the Company. It is intended that the Options under the Option Plan will
either qualify for treatment as incentive stock options under Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code"), and be designated
"Incentive Stock Options," or not qualify for such treatment and be designated
"Nonqualified Stock Options."
 
  The purpose of the Option Plan is to further the growth, development and
financial success of the Company and its Subsidiaries by providing additional
incentives to eligible Participants by assisting them in acquiring shares of
Common Stock and benefitting directly from the Company's growth, development
and financial success.
 
  Eligibility. Employees, directors, consultants and advisers of the Company
or a Subsidiary are eligible to receive grants of Options under the Option
Plan. More than one Option may be granted to any one Participant. Only
employees of the Company or a Subsidiary may be granted Incentive Stock
Options, and no Incentive Stock Option may be granted to any person who then
owns stock possessing more than 10% of the total combined voting power of all
classes of stock of the Company or of a Subsidiary unless (a) the Option Price
(as defined below) is at least 110% of the fair market value of the Common
Stock on the date of grant, and (b) the termination date of such Option is not
later than five years after the date such Option is granted.
 
  The aggregate fair market value (determined as of the time an Option is
granted) of the Common Stock for which any Participant may be granted
Incentive Stock Options, first exercisable in any calendar year under the
Option Plan, may not exceed $100,000.
 
  Administration. The Option Plan is administered by the full Board of
Directors of the Company or a committee thereof, and is presently administered
by the Compensation Committee of the Board (the "Committee").
 
  The Committee is authorized to administer the Option Plan and (a) to select
the Participants, to specify the number of shares of Common Stock with respect
to which Options are granted to each such Participant, to specify the Option
Price and the terms of Options, and in general to grant Options; (b) to
determine, subject to eligibility requirements, whether Options will be
Incentive Stock Options or Nonqualified Stock Options; (c) to determine the
dates upon which Options are granted and to provide for the terms and
conditions of the Options in a manner consistent with the Option Plan, which
terms and conditions need not be identical as to the various Options granted;
(d) to interpret the Option Plan; (e) to prescribe, amend and rescind rules
relating to the Option Plan; and (f) to determine the rights and obligations
of Participants under the Option Plan.
 
  Shares Subject to the Option Plan. The number of shares of Common Stock
which may be purchased pursuant to the exercise of Options granted under the
Option Plan is presently 900,000 shares. Pursuant to the Amendment, this
number would be increased to either 1,300,000 (if the Acquisition is never
consummated) or 2,400,000 (effective and conditioned upon the closing of the
Acquisition). The authorized number will be adjusted to reflect all stock
splits, stock dividends or similar capital changes. Upon the expiration or
termination of an outstanding Option which has not been exercised in full, any
unissued shares of Common Stock, will become available for the granting of
additional Options under the Option Plan. The maximum number of shares that
may be issued to any Participant is 500,000.
 
  Option Price. The purchase price per share (the "Option Price") of the
shares of Common Stock underlying each Option is determined by the Committee
with respect to each specific Option, but may not be less than the fair market
value of such shares on the date of grant. Should the Company acquire another
entity, the Committee may authorize the issuance of Options to the individuals
performing services for the acquired entity in substitution of stock options
previously granted them in connection with their performance of services for
such entity upon the conditions the Committee shall determine. This will not
be necessary in connection with the Acquisition, as no employees of
Electrotech hold any Electrotech stock options.
 
                                      89
<PAGE>
 
  Exercise of Options. Subject to all other provisions of the Option Plan,
each Option is exercisable for the full number of shares of Common Stock
subject thereto, in five equal cumulative annual installments, commencing one
year after the date of grant (provided the Participant is employed by the
Company at the time of vesting), or in such other installments and intervals
as the Committee may specifically determine in granting such Option. However,
each Option must provide that it shall become fully exercisable in not more
than five years after the date of grant. Each Option must terminate and
expire, and no longer be subject to exercise, ten years after the date of
grant, or at such earlier date as the Committee may otherwise determine. The
Option may be exercised by the Participant by giving written notice to the
Company specifying the number of full shares to be purchased and accompanied
by payment of the full purchase price.
 
  Option. Each Option granted under the Option Plan is evidenced by a written
stock option executed by the Company and delivered to the Participant.
 
  Non-transferability. No Option is assignable or transferable except by will
or by the laws of descent and distribution. During the Participant's lifetime,
any Option granted to him or her shall be exercisable only by him or her.
After the Participant's death, his Option may be exercised, prior to its
termination as provided by Section 13(b), only by his or her legal
representative, his or her legatee or another person who acquired the right to
exercise the Option by reason of the death of the Participant.
 
  Recapitalization, Reorganization, Merger or Consolidation. If the number of
outstanding shares of Common Stock of the Company changes or such shares are
exchanged for different securities through reorganization, merger,
consolidation, recapitalization, reclassification, stock split, stock dividend
or like capital adjustment, a proportionate adjustment will be made (a) in the
aggregate number of shares of Common Stock which may be issued pursuant to the
exercise of Options under the Option Plan, and (b) in the number, price and
kind of shares subject to any outstanding Option granted under the Option
Plan.
 
  Upon the dissolution or liquidation of the Company or upon any
reorganization, merger or consolidation in which the Company does not survive,
the Option Plan and each outstanding Option will terminate; provided, that
each Optionee to whom no substitute option has been tendered by the surviving
corporation will have the right to exercise in whole or in part any unexpired
Option issued to him or her, without regard to the installment provisions
thereof.
 
  Rights as a Shareholder. A Participant holding an Option has no rights as a
shareholder with respect to any shares covered by his or her Option, until the
date the stock certificate is issued for such shares. No adjustment will be
made for dividends or distributions or other rights for which the record date
is prior to the date such stock certificate is issued, except in connection
with certain recapitalizations, reorganizations, mergers or consolidations.
 
  Termination of Options. Each Option granted under the Option Plan sets forth
a termination date, which must not be later than ten years from the date such
Option is granted. Except where earlier termination is required by the terms
of the Option, all Options terminate and expire upon the first to occur of the
following events:
 
    (a) the expiration of 30 days from the date of such Participant's
  termination of employment, but if the Participant is disabled at the time
  of his or her termination of employment, the expiration is one year from
  the date of the Participant's termination of employment;
 
    (b) the expiration of 180 days from the date of the death of the
  Participant if his or her death occurs while he or she is employed by the
  Company or any of its Subsidiaries; or
 
    (c) the termination of the Option in connection with certain
  recapitalizations, reorganizations, mergers or consolidations.
 
  The termination of employment of a Participant will not accelerate or
otherwise affect the number of shares with respect to which an Option may be
exercised, and the Option may only be exercised with respect to that number of
shares which could have been purchased under the Option had the Option been
exercised by the Participant on the date of such termination.
 
                                      90
<PAGE>
 
  Withholding of Taxes. The Company will deduct and withhold from the wages,
salary, bonus and other income paid by the Company to the Participant the
requisite tax upon the amount of taxable income, recognized by the Participant
in connection with the exercise in whole or in part of any Option or the sale
of Common Stock issued to the Participant upon exercise of the Option, as may
be required from time to time under any federal or state tax laws and
regulations. This withholding of tax will be made from the Company's
concurrent or next payment of wages, salary, bonus or other income to the
Participant or by payment to the Company by the Participant of the required
withholding tax, as determined by the Committee.
 
  Termination of Option Plan. The Option Plan will terminate when all Options
granted have been fully exercised and all shares of Common Stock which may be
purchased pursuant to the exercise of such Options have been purchased or
expired but in any event not later than January 2001. However, the Board may,
at its discretion, terminate the Option Plan at any time. No such termination,
other than as provided for with respect to certain recapitalizations,
reorganizations, mergers or consolidations, will in any way affect any Option
then outstanding.
 
  Amendment of Option Plan and Options. The Board of Directors may amend or
modify the Option Plan and outstanding Options at any time, provided that no
such amendment or modification may adversely affect the rights and obligations
of the Participants with respect to their outstanding Options without their
consent. Generally, no amendment of the Option Plan may, without the approval
of the Company's shareholders, (a) modify the class of individuals eligible to
receive Incentive Stock Options, or (b) increase the number of shares
available for issuance, except in the event of certain changes to the
Company's capital structure.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  Based on current provisions of the Code and the existing regulations
thereunder, the anticipated federal income tax consequences with respect to
options granted under the Option Plan are as described below. This discussion
does not address the tax consequences arising under the laws of any foreign,
state or local jurisdiction.
 
  Incentive Stock Options. No taxable income will be recognized by a
Participant upon the grant of any Incentive Stock Option. Subject to the
following sentence, no taxable income will be recognized by a Participant upon
the exercise of any Incentive Stock Option so long as the Participant is an
employee of the Company from date of grant until 3 months before the date of
exercise. However, the amount by which the fair market value of Common Stock
purchased upon exercise of an Incentive Stock Option exceeds the Aggregate
Option Price of such stock constitutes an item of adjustment that could then
be subject to the alternative minimum tax in the year the option is exercised.
Additionally, the Company will not be entitled to any income tax deduction as
the result of the grant or exercise of an Incentive Stock Option.
 
  Any gain or loss resulting from the subsequent sale of Common Stock acquired
upon exercise of an Incentive Stock Option will be long term capital gain or
loss if such sale is made after two years from the grant of the option and
after one year from the exercise, so long as the Participant is an employee of
the Company from the date of grant until three months before the date of
exercise. In the event of the Participant's death or disability prior to
exercise of an Incentive Stock Option, special rules apply in determining
whether gain or loss upon sale of the stock acquired upon exercise of such
option will be taxable as long term capital gain or loss.
 
  If the subsequent sale of stock is made prior to the expiration of such two-
year and one-year periods, the Participant will recognize ordinary income in
the year of sale in an amount equal to the difference between the aggregate
Option Price (the "Aggregate Option Price") of the Common Stock and the fair
market value of the Common Stock on the date of exercise, although special
rules apply if such sale is a transaction in which a loss (if sustained) would
have been recognized by the Participant.
 
  If the sale of Common Stock received upon exercise of an option qualifies
for long term capital gain treatment, any gain from such a sale would be taxed
at the current maximum federal income tax rate of 28%; ordinary income is
currently taxed at a maximum federal income tax rate of 39.6%.

  Nonqualified Stock Options. At the time of the grant of a Nonqualified Stock
Option, no taxable income will be recognized by the Participant and the
Company will not be entitled to a deduction. Upon the exercise of a
Nonqualified Stock Option, the Participant generally will recognize taxable
income, and the Company will then be entitled to a deduction, in the amount by
which the then fair market value of the shares of Common Stock issued to such
Participant exceeds the Aggregate Option Price. Income recognized by the
Participant upon exercise of a Nonqualified Stock Option will be taxed as
ordinary income. Such income constitutes "wages" with respect to which the
Company is required to deduct and withhold federal and state income tax.
 
  Upon the subsequent disposition of shares of Common Stock acquired upon the
exercise of a Nonqualified Stock Option, the Participant will recognize
capital gain or loss in an amount equal to the difference between the proceeds
received upon disposition and the fair market value of such shares at the time
of exercise. If such shares have been held for more than one year at the time
of such disposition the capital gain or loss will be long term.
 
  Acceleration of Stock Options Upon Transfer of Control. Pursuant to the
Option Plan, the exercisability of Nonqualified Stock Options and Incentive
Stock Options may be accelerated. Such acceleration will likely be determined
to be, in whole or in part, a "parachute payment" for federal income tax
purposes if it arises from any events connected with a change of control of
the Company. If the present value of all of the Participant's parachute
payments exceeds three times the Participant's average annual compensation for
the past five years, the Participant will be subject to a special excise tax
of 20% on the "excess parachute payment." Such tax will be applied to the
amount of such parachute payment which is in excess of the greater of such
average annual compensation of the Participant or an amount which the
Participant establishes as reasonable compensation. In addition, the Company
will not be allowed a deduction for such "excess parachute payment."
 
  The foregoing summary of the effects of federal income taxation upon
Participants and the Company with respect to shares of Common Stock issued
under the Option Plan does not purport to be complete and reference is made to
the applicable provisions of the Code.

  The Audit Committee of the Board has selected Ernst & Young as independent
public accountants to audit the consolidated financial statements of PMT and
any subsidiaries thereof for the year ending December 31, 1996. A member of
that firm is expected to be present at the Annual Meeting, will have an
opportunity to make a statement if so desired, and will be available to

selection of Ernst & Young, if it should decline to act or otherwise become
incapable of acting, or if its employment is discontinued, the Audit Committee
will appoint independent public accountants for fiscal 1996. Proxies solicited
by the Board will be voted in favor of ratification unless shareholders
specify otherwise.

                        REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Plasma & Materials Technologies, Inc.
 
  We have audited the accompanying consolidated balance sheets of Plasma &
Materials Technologies, Inc. and subsidiary as of December 31, 1995 and 1994,
and the related consolidated statements of operations, shareholders' equity
(deficit), and cash flows for the year ended December 31, 1995, the ten month
period ended December 31, 1994 and the year ended February 28, 1994. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Plasma &
Materials Technologies, Inc. at December 31, 1995 and 1994, and the
consolidated results of their operations and their cash flows for the year
ended December 31, 1995, the ten month period ended December 31, 1994 and the
year ended February 28, 1994, in conformity with generally accepted accounting
principles.

1. SIGNIFICANT ACCOUNTING POLICIES
 
 Background
 
  Plasma & Materials Technologies, Inc. (the "Company") was incorporated in
California on December 24, 1985. The Company operates in one segment,
designing, manufacturing and marketing advanced high density, low pressure
plasma sources, process modules and plasma processing systems. These products
are used for etch and chemical vapor deposition applications and are sold to
semiconductor and flat panel display manufacturers worldwide.
 
  The consolidated financial statements of the Company include the accounts of
its wholly owned subsidiary. All significant intercompany accounts and
transactions have been eliminated.
 
 Interim Financial Data
 
  The unaudited financial statements of the Company for the six months ended
June 30, 1995 and 1996 have been prepared on the same basis as the audited
financial statements and, in the opinion of management, include all
adjustments (consisting only of normal recurring adjustments) necessary to
state fairly the financial information set forth therein, in accordance with
generally accepted accounting principles.
 
  The results of operations for the six months ended June 30, 1996 are not
necessarily indicative of results to be expected for the full fiscal year.
 
 Use of Estimates
 
  The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements
and accompanying notes. Actual results could differ from those estimates.
 
 Cash Equivalents
 
  Cash equivalents represent short-term investments that are highly liquid,
are of limited credit risk and have original maturities of three months or
less when purchased.
 
 Short-Term Investments
 
  Effective December 1995, the Company adopted Statement of Financial
Accounting Standards No. 115 ("SFAS 115"), "Accounting for Certain Investments
in Debt and Equity Securities." SFAS 115 requires investment securities to be
classified as trading, available for sale, or held to maturity. Management
determines the appropriate classification of its investments at the time of
purchase and reevaluates the classification at each balance sheet date. As of
December 31, 1995, all investments in the short-term investment portfolio are
classified as available for sale. Under SFAS 115, investments classified as
available for sale are required to be recorded at fair value and any temporary
difference between an investment's cost and its fair value is required to be
recorded as a separate component of shareholders' equity.
 
 Major Customers and Concentration of Credit Risk
 
  Accounts receivable consist primarily of amounts due from original equipment
manufacturers, end use customers, and distributors within the Company's
industry. At December 31, 1994, two customers represented
 
                                      F-8

                            31, 1995 IS UNAUDITED)
50% and 23%, respectively, of the Company's total accounts receivable. At
December 31, 1995, five customers represented 26%, 25%, 15%, 14% and 12%,
respectively, of the Company's total accounts receivable.
 
  The Company performs credit evaluations and analysis of amounts due from its
customers; however, the Company does not require collateral. Credit losses
have been within management's expectations and an estimate of uncollectible
accounts has been provided for in the financial statements.
 
  Total revenue includes amounts from certain individual customers that exceed
10% of total revenue. Revenue from two customers represented 46% and 39% each
of total revenue for the year ended February 28, 1994, revenue from six
customers represented 19%, 17%, 17%, 15%, 15% and 12% each of total revenue
for the ten months ended December 31, 1994, and revenue from five customers
represented 19%, 15%, 12%, 11% and 11% each of total revenue for the year
ended December 31, 1995.
 
  The Company's revenue by geographic area approximated the following:

 Property, Equipment and Leasehold Improvements
 
  Property, equipment and leasehold improvements are stated at cost.
Depreciation and amortization is computed using the straight-line method over
the estimated useful lives of the assets (5 years) or the lease term,
whichever is shorter.
 
 Revenue Recognition
 
  Product sales consist primarily of system, component and spare parts sales.
Revenues related to system, component and spare parts sales are recognized
upon shipment and transfer of title or upon customer acceptance and transfer
of title in the case of demonstration inventory unit sales (see Note 3).
Estimated costs to be incurred by the Company related to product installation
(which are not significant) and warranty fulfillment are accrued at the date
of shipment.

  License fee revenue is derived from the grant of the non-exclusive rights to
use, sell and manufacture certain technologies developed by the Company.
 
 Advertising Expense
 
  The cost of advertising is expensed as incurred. The Company incurred
$55,772, $99,509 and $44,306 of advertising costs in the year ended February
28, 1994, the ten months ended December 31, 1994 and the year ended December
31, 1995, respectively.
 
 Research and Development Costs
 
  Research and development costs are expensed as incurred.
 
 Stock Based Compensation
 
  The Company grants stock options for a fixed number of shares to employees
with an exercise price equal to the fair value of the shares at the date of
grant. The Company accounts for stock option grants in accordance with APB
Opinion No. 25, Accounting for Stock Issued to Employees ("APB No. 25") and,
accordingly, recognizes no compensation for the stock option grants.
 
 Accounting for Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes ("SFAS No.
109"). Under SFAS No. 109, the liability method is used in accounting for
income taxes. Under this method, deferred tax assets and liabilities are
determined based on differences between financial reporting and tax basis of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.
 
 Net Income (Loss) Per Share
 
  Net income (loss) per share is computed using the weighted average number of
shares of Common Stock outstanding. Common equivalent shares from stock
options and warrants (using the treasury stock method) have been included in
the computation when dilutive, and common equivalent shares from the
redeemable convertible Preferred Stock and convertible Preferred Stock which
converted into Common Stock in connection with the Company's Initial Public
Offering are included as if converted at the original date of issuance, even
though inclusion is anti-dilutive. Pursuant to the Securities and Exchange
Commission ("SEC") Staff Accounting Bulletins, all common and common
equivalent shares issued by the Company at an exercise price below the Initial
Public Offering price of $14.00 per share during the twelve-month period prior
to the offering (cheap stock) have been included in the calculation as if they
were outstanding for all periods presented (using the treasury stock method at
the Initial Public Offering price of $14.00 per share and the if-converted
method for redeemable convertible Preferred Stock and convertible Preferred
Stock) through the ten month period ended December 31, 1994. For the year
ended December 31, 1995, such cheap stock shares were treated as being
outstanding through the date of the Initial Public Offering.

 Impact on Financial Statements of Recently Issued Accounting Standards
 
  In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of
("SFAS No. 121"), which will be effective for the Company's fiscal year ending
December 31, 1996. SFAS No. 121 requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are
presented and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. SFAS No. 121 also addresses
the accounting for long-lived assets that are expected to be disposed of. The
Company will adopt SFAS No. 121 in the first quarter of 1996 and, based on
current circumstances, does not believe the effect of adoption will be
material.
 
  In October 1995, the FASB issued Statement of Financial Accounting Standards
No. 123, Accounting for Awards of Stock-Based Compensation to Employees ("SFAS
No. 123"), which will be effective for the Company's fiscal year ending
December 31, 1996. SFAS No. 123 provides alternative accounting treatment to
APB No. 25 with respect to stock-based compensation and requires certain
additional disclosures, including disclosures if the Company elects not to
adopt the accounting requirements of SFAS No. 123. The Company will adopt the
disclosure requirements of SFAS No. 123 in the first quarter of 1996, but will
elect to continue to measure compensation costs following present accounting
rules under APB No. 25. Consequently, the Company will provide pro forma
disclosures of what net income and earnings per share would have been had the
fair market value method of SFAS No. 123 been used for the relevant periods.
 
  Reclassifications
 
  Certain amounts in 1994 and 1993 have been reclassified in the Consolidated
Financial Statements to be consistent with the 1995 presentation.
 
2. FINANCIAL INSTRUMENTS
 
  The Company's financial instruments consist of cash, cash equivalents,
short-term investments, accounts receivable, accounts payable, capital lease
obligations and borrowings under the revolving line of credit. The carrying
amounts of these financial instruments approximates their fair value.
 
  Information about contractual maturities of short-term investments at
December 31, 1995 is as follows:

                            31, 1995 IS UNAUDITED)
 
  At December 31, 1995, $12,006,158 of investments in debt securities are
included in cash and cash equivalents on the accompanying balance sheet
because their original maturity date is three months or less when purchased.
 
  Gross unrealized holding gains and losses on sales of short-term investments
were not significant as of or for the year ended December 31, 1995. There were
no realized gains and losses on sales of short-term investments during the
year ended December 31, 1995. The Company manages its cash equivalents and
short-term investments as a single portfolio of highly marketable securities,
all of which are intended to be available to meet the Company's current cash
requirements.
 
  The Company invests in a variety of financial instruments such as commercial
paper, commercial bonds, and municipal bonds. The Company, by policy, limits
the amount of credit exposure with any one financial institution or commercial
issuer.
 
3. DEMONSTRATION INVENTORY
 
  Demonstration or evaluation units represent completed systems located at
certain strategic customer sites or at the Company's facilities. The Company
provides these demonstration systems at no charge for a specified evaluation
period. All operating costs incurred during the evaluation period are paid by
the customer. At the conclusion of the agreed upon evaluation period, provided
that the equipment performs to required specifications, management expects
that the customer, while not obligated to do so, will purchase the system.
Demonstration inventory is stated at lower of cost or estimated net realizable
value. Demonstration inventory is not amortized.
 
4. REVOLVING LINE OF CREDIT
 
  At December 31, 1995, the Company has a revolving line of credit agreement
with a commercial bank which provides borrowings up to the lesser of
$3,000,000 or 75% of eligible accounts receivable. Interest is payable monthly
for borrowings on accounts receivable at the bank prime rate plus 1.5% (9.5%
at December 31, 1995.) The revolving line of credit agreement expires on June
5, 1996. At December 31 ,1995, there were no borrowings outstanding under the
revolving credit line and $3,000,000 was available for borrowings under the
agreement. The agreement places certain restrictions on the Company which
among other things, prohibit the Company from paying cash dividends or
repurchasing its stock, and requires the Company to comply with certain
financial ratios and covenants.
 
5. DEVELOPMENT CONTRACTS
 
  In August 1994, the Company entered into an original equipment manufacturing
and joint development agreement with a customer. This arrangement ended in
March 1995. Under this agreement, the Company incurred costs on behalf of the
customer and received reimbursement of approximately $1,000,000 in 1994 and
$350,000 in 1995. Such costs were primarily for the customer's share of
supplies and prototype materials used under the agreement. The reimbursement
of costs incurred were netted against the related research and development
expense. Any technology developed under this agreement is jointly owned by the
Company and the customer.
 
6. INCOME TAXES
 
  The Company's provision for income taxes consists primarily of the minimum
state taxes required in each of the periods presented of $800 and foreign
income taxes of $50,000 in the year ended February 28, 1994 and $53,600 in the
ten month period ended December 31, 1994. Federal income taxes have not been
provided for in any of the periods presented as the Company incurred a loss
for these periods.

resulting in approximately $40,093,235 of net proceeds to the Company.
 
  In connection with the Initial Public Offering, the Board of Directors

13. SUBSEQUENT EVENTS
 
 PMT CVD Partners, L.P.
 
  On March 29, 1996, the Company entered into a number of agreements with PMT
CVD Partners, L.P. (the "Limited Partnership") and the limited partners
thereof (the "Limited Partners"). The Limited Partnership was formed to fund
research and development costs and expenses relating to chemical vapor
deposition ("CVD") technology and applications. An aggregate of approximately
$5,350,000 is available to the Limited Partnership to fund such research and
development efforts. The Limited Partnership owns the rights to the technology
developed. PMT has entered into a license agreement with the Limited
Partnership whereby PMT is obligated to pay stated royalties to the Limited
Partnership on sales of related products, and the royalty percentage will vary
based on the geographic location of the sale. There is no provision for
royalty payments to the Limited Partners in fiscal 1996. PMT has been granted
an exclusive option to purchase all of the Limited Partners' interest in the
Limited Partnership, based on an established purchase price formula which
terminates PMT's obligation under the license agreement. PMT may exercise such
option at its sole discretion.
 
  PMT has agreed to provide certain personnel to the Limited Partnership to
perform such research and development activities. PMT will be paid for such
services at an amount equal to its actual direct costs, as defined, plus a
stated percentage of such costs. During the quarter and six months ended June
30, 1996, the amount of research and development costs incurred, including the
stated percentage of 250% of direct costs, with respect to CVD technology and
applications was $459,600 and $848,678, respectively and is reflected in
contract revenue in the accompanying statement of operations.
 
 Acquisition
 
  On July 17, 1996 the Company executed a definitive agreement to purchase
Electrotech Ltd. and Electrotech Equipment Ltd., United Kingdom corporations
for $75,000,000 in cash and the issuance of 5,600,000 shares of the Company's
common stock. The agreement is subject to certain conditions including
obtaining shareholder approval, and obtaining appropriate financing. Included
in other assets are approximately $917,904 of direct costs of the acquisition.
If the agreement is terminated, except in certain circumstances, the Company
will be required to pay a $1,000,000 termination fee which along with all
direct acquisition costs incurred will be charged to operations in the period
the contract is terminated.

lesser of 80% of eligible accounts receivable or $3,000,000. Interest on the

The Agreement also provides for equipment loans which allows the Company to
borrow up to the lesser of 80% of eligible equipment purchases or $3,000,000,
subject to certain limits. Interest on borrowings under the equipment line is
payable monthly at prime plus 1.5%. At June 30, 1996, there were no balances

                        REPORT OF INDEPENDENT AUDITORS
 
To the directors of Electrotech Equipments Limited and Electrotech Limited
 
  We have audited the accompanying combined balance sheets of Electrotech
Equipments Limited and Electrotech Limited as of June 30, 1995 and 1996 and
the related profit and loss accounts and statements of cash flows for each of
the three years in the period ended June 30, 1996. These combined financial
statements are the responsibility of the companies' directors. Our
responsibility is to express an opinion on these combined financial statements
based on our audits.
 
  We conducted our audits in accordance with United Kingdom auditing standards
which do not differ in any significant respect from United States generally
accepted auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurances about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting and amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by the management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
  In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of
Electrotech Equipments Limited and Electrotech Limited as of June 30, 1995 and
1996 and the results of their operations and their cash flows for each of the
three years in the period ended June 30, 1996 in conformity with accounting
principles generally accepted in the United Kingdom which differ in certain
respects from those followed in the United States (see Note 29 of the notes to
the combined Financial Statements).

2. ACCOUNTING POLICIES--(CONTINUED)
 
 Foreign exchange
 
  The profit and loss accounts and balance sheets of the overseas subsidiaries
have been translated into sterling at the average rates of exchange for the
year and the rates of exchange ruling at the balance sheet date respectively.
Exchange differences arising between the translation into sterling of the net
assets of these subsidiaries at rates ruling at the beginning and end of the
year are dealt with through retained earnings and reserves.
 
 Leasing
 
  Tangible fixed assets acquired under finance leases or hire purchase
contracts are capitalized and depreciated in the same manner as other tangible
assets. The related obligations, net of future finance charges, are included
in creditors.
 
  Rentals payable under operating leases are charged to the profit and loss
account on a straight line basis over the period of the lease.
 
 Government grants
 
  Government grants are credited to the profit and loss account by
installments over the expected useful economic lives of the assets to which
they relate.
 
 Pension costs
 
  Electrotech Equipments Limited, Electrotech Limited and their subsidiary
companies operate a pension scheme known as "The Electrotech Retirement
Benefits Scheme" which undertakes to provide retirement benefits to
participating employees based upon their final pensionable salary. The assets
of the scheme are administered by the Trustees and are separate from those of
Electrotech Equipments Limited, Electrotech Limited and their subsidiaries.
 
  Employer contributions to the scheme are made in accordance with the
recommendations of an independent qualified actuary based upon his triennial
valuations of scheme assets and calculations of funding requirements to meet
future benefits. These contributions are charged to profit and loss account
when incurred.
 
3. SALES

  No provision has been made for the potential tax liability that would arise
on the disposal of the freehold land and buildings at the revalued amount
shown in the balance sheet. The potential tax liability at June 30, 1996
amounts to (Pounds)500,000 (1995: (Pounds)500,000), but no provision for this
is required since the directors have no plans to dispose of the property in
the foreseeable future and, in the event of a disposal, it is considered that
no tax liability would arise after taking account of "rollover" relief.
 
  In addition, no provision has been made for the potential tax liability that
would arise on the disposal of land and buildings on which Scientific Research
Allowances have been claimed. The potential liability at June 30, 1996 amounts
to (Pounds)246,000 (1995: (Pounds)246,000).

26. PENSIONS
 
  Electrotech Equipments Limited, Electrotech Limited and their subsidiaries
operate a pension scheme known as "The Electrotech Retirements Benefits
Scheme" which undertakes to provide retirement benefits to participating
employees based upon their final pensionable salary. The assets of the scheme
are administered by the Trustees and are separate from those of the companies.
 
  Employer contributions to the scheme are made at rates recommended by a
qualified actuary following his triennial valuation of the fund. At the date
of the latest actuarial valuation, April 6, 1993, the market value of the
assets of the scheme was (Pounds)4,562,000 which represented 145% of the
benefits that had accrued to members, after allowing for expected future
increases in earnings.
 
  The assumptions which have the most significant effect on the results of the
valuation are those relating to the rate of return on investments and the
rates of increase in salaries and pensions. It has been assumed that the
investment return is 2% higher per annum than future salary and pension
increases.
 
  Employer contributions to the scheme from July 1, 1994 to April 30, 1995
were made at the rate of 6% of pensionable salaries, and from May 1, 1995 at
the rate of 8.8% of pensionable salaries.
 
  The group also makes contributions to a Group Personal Pension plan for
employees who are not members of the final salary scheme. Total contributions
to the group scheme and personal pension plan in the year ended June 30, 1996
amounted to (Pounds)298,000 (1995: (Pounds)242,000).
 
27. LEASING COMMITMENTS

29. DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED
    KINGDOM AND THE UNITED STATES
 
  The combined financial statements are prepared under accounting principles
generally accepted in the United Kingdom ("UK GAAP") which differ in certain
respects from United States generally accepted principles ("US GAAP").
Differences estimated to have a significant effect on combined net income and
shareholders' equity are set out below.
 
 Revaluation of Land and Buildings
 
  Certain land and buildings were revalued in 1991 on the basis of their value
to the business and they are included in these combined financial statements
at that valuation less subsequent depreciation. Under US GAAP, such
revaluations would not be reflected in the financial statements. Land and
buildings would be included at historical cost under US GAAP with depreciation
computed on such cost.
 
 Deferred Taxation
 
  Provision is made for deferred taxation using the liability method on all
material timing differences to the extent that it is probable that the
liabilities will crystallize in the foreseeable future. Under US GAAP, as set
out in Statement of Financial Accounting Standards No. 109 "Accounting for
Income Taxes", deferred taxation is generally provided on a full liability
basis on all temporary differences.
 
 Pensions
 
  Under UK GAAP the cost of providing pensions is accounted for over the
working lives of the employees in the scheme. Under US GAAP, FAS 87 requires
that a specific actuarial approach is applied for measuring the pension cost,
the objective of which is to recognize in each accounting period the cost of
providing the pension benefits earned by employees in that period.
 
  The following is a summary of the effect of the above differences on profit
for the financial year (net income) and equity shareholders' funds:

 Consolidated Cash Flow Statement
 
  The consolidated statements of cash flows prepared in accordance with UK
GAAP present substantially the same information as that required under US
GAAP. UK GAAP and US GAAP differ, however, with regard to classification of
items within the statements and as regards the definition of cash and cash
equivalents.
 
  Under US GAAP, cash and cash equivalents would not include bank overdrafts
and borrowings with initial maturities of less than three months. Under UK
GAAP, cash flows are presented separately for operating activities, servicing
of finance and returns on investments, taxation, investing activities and
financing activities. US GAAP, however, requires only three categories of cash
flow activity to be reported: operating, investing and financing. Cash flows
from taxation and servicing of finance and returns on investments shown under
UK GAAP would be included as operating activities under US GAAP.
 
  The categories of cash flow activity under US GAAP can be summarized as
follows:

                        REPRESENTATIONS AND WARRANTIES
                          OF EACH OF THE SHAREHOLDERS
 
  Except as disclosed in the letter of disclosure (the "Shareholders
Disclosure Letter") delivered to Buyer in connection herewith and initialled
by the Buyer and each of the Shareholders for identification, each of the
Shareholders severally and not jointly represents and warrants to, and agrees
with, Buyer as follows:
 
  3.1 Title to Shares. Such Shareholder has good and marketable title, and
full beneficial ownership, in and to the ET Shares shown as being held of
record by such Shareholder on Exhibit A hereto, and such ET Shares are, and on
the Closing Date will be, free and clear of any and all liens, security
interests, mortgages, deeds of trust, pledges, claims, rights of first
refusal, options, equities, encumbrances, restrictions, preemptive or
subscription rights or other rights of third parties ("Encumbrances"). There
are no voting trusts or other agreements, arrangements or understandings with
respect to the voting of any of the ET Shares to which such Shareholder is a
party. Upon the consummation of the transactions contemplated by this
Agreement, including delivery by Buyer of the consideration set forth in
Section 1.4 hereof, Buyer will acquire good and marketable title to such ET
Shares, free and clear of any and all Encumbrances.
 
  3.2 Authority. This Agreement has been duly executed and delivered by such
Shareholder and constitutes the legal, valid and binding obligations of such
Shareholder, enforceable against such Shareholder in accordance with its
terms, subject to applicable bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting creditors' rights generally and
subject to general equitable principles (regardless of whether such
enforceability is considered in a proceeding in equity or at law).
 
  3.3 No Violation. The execution, delivery and performance of this Agreement
by such Shareholder and the consummation by such Shareholder of the
transactions contemplated hereby will not (a) violate any provision of law,
rule, regulation, order, writ, judgment, injunction, decree, determination or
award applicable to such Shareholder, (b) require the consent, waiver,
approval or authorization of or any filing by such Shareholder with any person
or governmental authority, or (c) violate, result (with or without notice or
the passage of time, or both) in a breach of, or give rise to the right to
terminate, accelerate or cancel any obligation under, or require the payment
of any fee, or constitute (with or without notice or the passage of time, or
both) a default under, any indenture, mortgage, lien, order, judgment,
ordinance, regulation, decree or other agreement or instrument to which such
Shareholder is subject or bound which, in any such case described in clauses
(a) through (c), could reasonably be expected to materially and adversely
affect or interfere in any way with such Shareholder's ability to consummate
the transactions contemplated by this Agreement, or (d) result in the creation
of any Encumbrance upon any of the ET Shares shown as being held of record by
such Shareholder on Exhibit A hereto. There are no actions, proceedings,
claims, complaints, grievances or investigations pending or, to the knowledge
of such Shareholder, threatened against such Shareholder that could be
reasonably expected to materially and adversely affect such Shareholder's
ability to consummate the transactions contemplated by this Agreement.
 
  3.4 Brokers. Such Shareholder has not paid or become obligated to pay any
fee or commission to any broker, finder, investment banker or other
intermediary in connection with this Agreement.

such Shareholder has no legal obligation, absolute or contingent, to any other
person, firm or entity to sell, directly or indirectly, capital stock,
material assets or business of either Company or any Subsidiary or to effect
any merger, consolidation, liquidation, dissolution, recapitalization or other
reorganization of either Company or any Subsidiary or to enter into any
agreement with respect thereto.

  3.6 Regulation S Representations and Covenants.
 
    (a) Such Shareholder understands and acknowledges that: (i) the Buyer
  Shares have not been and will not be registered under the Securities Act of
  1933, as amended (the "Securities Act"), or under any state securities or
  blue sky laws, and may not be offered, sold, transferred, pledged or
  otherwise disposed of in the United States or to, or for the account or
  benefit of, any "U.S. person" (as defined in Regulation S), unless they are
  registered under the Securities Act and any applicable state securities or
  blue sky laws in exemptions from such laws are available; and (ii) the
  Buyer Shares are being offered and sold in a manner intended to comply with
  the conditions contained in Regulation S, which permits securities to be
  sold in "offshore transactions" (as defined in Regulation S), subject to
  certain terms and conditions. Such Shareholder represents and warrants that
  he or she is not purchasing the Buyer Shares in any transaction or series
  of transactions that, although in technical compliance with Regulation S,
  is part of a plan or scheme to evade the registration provisions of the
  Securities Act.
 
    (b) Such Shareholder is not a "U.S. person" and is not acquiring the
  Buyer Shares for the benefit of any "U.S. person." Such Shareholder is
  knowledgeable, sophisticated and experienced in making, and qualified to
  make, decisions with respect to investments in securities such as the Buyer
  Shares and has requested, received, reviewed and considered all information
  he or she deems relevant in making a decision to acquire the Buyer Shares.
 
    (c) During the period of 40 days following the Closing (the "Restricted
  Period"), such Shareholder will not engage in any activity for the purpose
  of, or which may reasonably be expected to have the effect of, conditioning
  the market in the United States for the Buyer Shares, or offer, sell,
  transfer, pledge or otherwise dispose of the Buyer Shares in the United
  States or to, or for the account or benefit of a "U.S. person." Any
  proposed offer, sale, transfer, pledge or other disposition of any of the
  Buyer Shares prior to the end of the Restricted Period will be subject to
  the prior delivery by the Shareholder to the Buyer of: (i) a written
  certification that the Buyer Shares have not been offered or sold in the
  United States or to, or for the account or benefit of, any "U.S. person";
  and (ii) a written certification of the proposed transferee, reasonably
  acceptable to the Buyer, confirming that such transferee is outside the
  United States, is not a "U.S. person," and that the transfer is otherwise
  permissible under Regulation S. Such Shareholder 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) the Buyer Shares otherwise than in compliance with the Securities Act,
  any applicable state securities or blue sky laws and any applicable
  securities laws of jurisdictions outside the United States, and the rules
  and regulations promulgated thereunder.
 
    (d) Such Shareholder acknowledges that if he or she sells all or any part
  of the Buyer Shares in the United States, he or she (and/or certain persons
  who participate in any such sale) may be deemed, under certain
  circumstances, to be an "underwriter," as defined in Section 2(11) of the
  Securities Act. Such Shareholder understands that he or she should consult
  with United States legal counsel prior to offering or selling all or any
  part of the Buyer Shares in the United States.
 
    (e) During the period that is five business days immediately prior to the
  Closing, such Shareholder will not, and from the Closing and through the
  expiration of the Restricted Period, such Shareholder will not, directly or
  indirectly, execute or effect or cause to be executed or effected any short
  sale, option or equity swap transaction in or with respect to the Common
  Stock of Buyer or any other derivative security transaction, the purpose or
  effect of which is to hedge or transfer to a third party all or any part of
  the risk of loss associated with such Shareholder's ownership of the Buyer
  Shares.
 
    (f) Such Shareholder acknowledges and agrees that the certificates
  evidencing the Buyer Shares shall have a legend substantially as follows:
 
    "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
    CONTRACTUAL RESTRICTIONS PURSUANT TO WHICH, PRIOR TO [40 DAYS AFTER THE
    CLOSING] (THE "TERMINATION DATE"), NO OFFER, SALE, TRANSFER, PLEDGE OR
    OTHER DISPOSITION (COLLECTIVELY, A "DISPOSITION") OF THE SECURITIES
 
                                       4
<PAGE>
 
    REPRESENTED BY THIS CERTIFICATE MAY BE MADE UNLESS (A) THE DISPOSITION
    IS MADE OUTSIDE THE UNITED STATES AND TO, OR FOR THE ACCOUNT OR BENEFIT
    OF, ANY PERSON WHO IS NOT A "U.S. PERSON," AND (B) PRIOR TO SUCH
    DISPOSITION, THE BENEFICIAL OWNER OF SUCH SHARES AND THE PROPOSED
    TRANSFEREE SUBMIT A CERTIFICATION AS DESCRIBED IN THAT CERTAIN SHARE
    PURCHASE AGREEMENT PURSUANT TO WHICH THESE SECURITIES WERE ISSUED. SUCH
    CONTRACTUAL RESTRICTIONS TERMINATE ON, AND THIS LEGEND MAY BE REMOVED
    UPON PRESENTATION OF THIS STOCK CERTIFICATE TO THE TRANSFER AGENT OR
    THE ISSUER AT ANY TIME AFTER THE TERMINATION DATE."
 
    (g) Such Shareholder will be entitled to obtain from the Buyer's transfer
  agent (the "Transfer Agent") at any time from the first business day
  following the Restricted Period one or more substitute stock certificates
  without the restrictive legend described above upon surrender to the
  Transfer Agent of the stock certificate or certificates delivered pursuant
  to the preceding paragraph which, in the case of any holder subsequent to a
  Shareholder must be duly endorsed for transfer or surrender and, in any
  event, must be accompanied by payment of any amount necessary to be paid
  pursuant to any transfer tax or similar governmental charge relating to
  such transaction.
 
                                  ARTICLE IV
 
                        REPRESENTATIONS AND WARRANTIES
                          OF THE MAJORITY SHAREHOLDER
 
  Except as disclosed in the letter of disclosure (the "Company Disclosure
Letter") delivered to Buyer in connection herewith and initialled by the Buyer
and the Majority Shareholder for identification, the Majority Shareholder
represents and warrants to Buyer as follows:
 
  4.1 Corporate Organization. Each of the Companies is a corporation duly
organized, validly existing and in good standing under the laws of England,
with all requisite corporate power and authority to own, operate and lease its
properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed could
reasonably be expected, individually or in the aggregate, to have a material
adverse effect upon the financial condition, prospects or results of
operations of the Companies and the Subsidiaries considered as a whole (a
"Company Material Adverse Effect"). True and complete copies of the Memorandum
and Articles of each Company have been delivered to Buyer.
 
  4.2 Subsidiaries. A true and complete list of all direct and indirect
subsidiaries other than the Dormant Subsidiaries (each, a "Subsidiary" and
collectively, the "Subsidiaries") of each of the Companies is set forth in the
Company Disclosure Letter. The Company Disclosure Letter also identifies the
inactive subsidiaries of the Companies (the "Dormant Subsidiaries"). None of
the Dormant Subsidiaries has any material assets or liabilities (contingent or
absolute) and none presently engages in any business activity. Since March 31,
1996 no Company or Subsidiary has paid any amounts to any of the Dormant
Subsidiaries, no amounts will be so paid at any time hereafter, and any net
intercompany payables of the Company and its Subsidiaries to the Dormant
Subsidiaries shall be forgiven or cancelled at the closing. As used in this
Article IV, references to a "Company" or the "Companies" shall, if appropriate
given the context of the representations being made, include each relevant
Subsidiary, even though no specific reference to any Subsidiary is so made.
Each Subsidiary is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation, except that with
respect to the U.K. Subsidiaries, such Subsidiaries have been duly registered
in England and Wales under the Companies Act 1985. In each case such
Subsidiaries have all requisite corporate power and authority to own, operate
and lease its properties and to carry on its business as it is now being
conducted, and is qualified or licensed to do business and is in good standing
in each jurisdiction in which the failure to be so qualified or licensed could
reasonably be expected, individually or in the aggregate, to have a Company
Material Adverse
 
                                       5

Effect. All of the issued shares of capital stock of each such Subsidiary have
been duly and validly authorized and issued, are fully paid and non-
assessable, and are owned directly or indirectly by one of the Companies, free
and clear of any and all Encumbrances. Except with respect to the ownership of
the Subsidiaries by the Companies, neither Company nor any Subsidiary owns,
directly or indirectly, any stock, partnership interest, joint venture
interest or other security, investment or interest in any other corporation,
organization, partnership, limited liability company or entity.
 
  4.3 Share Capital; Title to ET Shares.
 
    (a) Capital Stock. As of the date hereof, the authorized share capital of
  (i) ET consists in its entirety of five hundred seventy five (575) shares
  of (Pounds)1 each, of which five hundred seventy (570) are issued and
  outstanding, and (ii) ETE consists in its entirety of ten thousand (10,000)
  shares of (Pounds)1 each, eighty-two (82) of which are Class A Shares and
  nine thousand nine hundred and eighteen (9,918) of which are Class B
  shares, all of which are issued and outstanding. All of the issued shares
  of each of the Companies have been duly authorized and validly issued and
  are fully paid and non-assessable and except as set forth in the Company
  Disclosure Letter, free of preemptive rights with respect thereto and were
  issued in compliance with all applicable securities laws and regulations.
  There are no voting trusts or other agreements, arrangements or
  understandings with respect to the voting of the shares of the Companies to
  which either Company or, to the best knowledge (as defined in Section 9.2
  hereof) of the Companies, any other person is a party. There are no
  registration rights, subscriptions, options, warrants, rights, convertible
  securities or other agreements or commitments of any character relating to
  the issued or unissued share capital or other securities of either of the
  Companies and there are no outstanding contractual obligations of either of
  the Companies to repurchase, redeem or otherwise acquire or sell, issue or
  otherwise transfer any of the share capital thereof.
 
    (b) Title to Shares. Exhibit A hereto sets forth the record ownership of
  the ET Shares. To the best knowledge of the Companies, (i) each Shareholder
  has good and marketable title in and to the respective ET Shares set forth
  opposite such Shareholder's name on Exhibit A hereto, (ii) the ET Shares
  are, and on the Closing Date will be, free and clear of any and all
  Encumbrances, and (iii) on the Closing, upon consummation of the
  transactions contemplated by this Agreement, including delivery by Buyer of
  the consideration set forth in Sections 1.3 and 1.4 hereof, Buyer will
  acquire good and marketable title to all of the ET Shares and the US
  Shares, free and clear of any and all Encumbrances.
 
  4.4 Authority. Each Company has the full corporate power and authority to
execute and deliver this Agreement and each other agreement contemplated
hereby, to carry out its obligations hereunder and thereunder and to
consummate the transactions contemplated on its part hereby and thereby. The
execution, delivery and performance by each Company of this Agreement and the
consummation of the transactions contemplated on its part hereby have been
duly authorized by its Board of Directors and by the shareholders thereof, and
no other corporate proceedings on the part of either Company are necessary to
authorize the execution and delivery of this Agreement by such Company to
consummate the transactions contemplated hereby. This Agreement has been duly
executed and delivered by each Company and constitutes the legal, valid and
binding obligations of each Company, enforceable against each Company in
accordance with its terms, subject to applicable bankruptcy, insolvency,
moratorium, reorganization or similar laws affecting creditors' rights
generally and subject to general equitable principles (regardless of whether
such enforceability is considered in a proceeding in equity or at law). Each
other agreement to be executed in connection with this Agreement on or prior
to the Closing Date will be duly executed and delivered by each Company, and
will constitute a legal, valid and binding obligation of each Company,
enforceable against each Company in accordance with its respective terms,
subject to applicable bankruptcy, insolvency, moratorium, reorganization, or
similar laws affecting creditors' rights generally and subject to general
equitable principles (regardless of whether such enforceability is considered
in a proceeding in equity or at law).
 
  4.5 No Violations or Consents. The execution, delivery and performance of
this Agreement by the Companies and the consummation by them of the
transactions contemplated hereby will not (a) violate or conflict
 
                                       6
<PAGE>
 
with any provision of any law specifically applicable to their business or by
which any property or asset of theirs is bound, (b) require the consent,
waiver, approval, license or authorization of or any filing by them with any
public authority (other than (i) if necessary, the filing of a pre-merger
notification report under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act") and applicable U.K./EEC antitrust statutes,
and (ii) any other filings and approvals expressly contemplated by this
Agreement), (c) violate, conflict with, result in a breach of or the
acceleration of any obligation under, or constitute a default (or an event
which with notice or the lapse of time or both would become a default) under,
or give to others any right of termination, amendment, acceleration or
cancellation of, or result in the creation of any Encumbrance on any property
or asset of theirs pursuant to any provision of any charter or by-law,
indenture, mortgage, lien, lease, agreement, contract, instrument, order,
judgment, ordinance, regulation or decree to which either of the Companies are
subject or by which either Company or its respective properties or assets are
bound, or (d) result in a loss or adverse modification of any license, permit,
certificate, franchise or contract granted to or otherwise held by either of
the Companies which, in any such case described in clauses (a) through (d),
could reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect.
 
  4.6 Litigation. There are no actions, proceedings, claims, complaints,
grievances, investigations or unfair labor practice complaints or grievances
or investigations (collectively, "Actions") pending or, to the best knowledge
of the Companies, threatened against either Company, any Subsidiary or any of
their assets or properties before any court or governmental or regulatory
authority or body or arbitrator (an "Authority") which could reasonably be
expected to have a Company Material Adverse Effect. There are no Actions
pending or, to the knowledge of the Companies, threatened against either
Company or any Subsidiary that could be reasonably expected to materially and
adversely affect on their part the consummation of the transactions
contemplated by this Agreement. None of the assets or property of either
Company or any Subsidiary is subject to any order, judgment, injunction, writ
or decree, which could reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.
 
  4.7 Financial Statements. Each Company has previously delivered to Buyer its
financial statements for the years ended June 30, 1991, 1992, 1993, 1994 and
1995, as audited by Watts Gregory & Daniel, which financial statements
included (a) a consolidated profit and loss account for the year then ended,
(b) a consolidated balance sheet as at such date, (c) a company balance sheet
as at such date, (d) a consolidated cash flow statement for the year then
ended, (e) a consolidated schedule of tangible fixed assets as at such date,
(f) a company schedule of tangible fixed assets as at such date and (g) notes
to the accounts for the year then ended (collectively, the "Audited Financial
Statements"). Each Company has also previously delivered to Buyer its
unaudited management accounts at March 31, 1996 (the "Unaudited Financial
Statements," and collectively with the Audited Financial Statements, the
"Financial Statements"). The Audited Financial Statements give a true and fair
view of the Companies as at the date (the "Accounting Date") on which such
accounts were made up and of the profits of each of the Companies for the
accounting reference period ending on that date, comply with all current
SSAP's applicable to a United Kingdom company and with the requirements of the
Companies Act 1985 and with all other applicable legislation, and each of the
said Audited Financial Statements properly reflect the financial position of
each of the Companies as at the relevant Accounting Date and were prepared in
accordance with the historical cost convention. "SSAP" for this purpose means
a Statement of Standard Accounting Practice in force at the relevant
Accounting Date as issued by the Institute of Chartered Accountants in England
and Wales. The Unaudited Financial Statements have been prepared in accordance
with the books and records of the Companies, contain no material inaccuracies,
and follow the same principles as consistently applied to the Audited
Financial Statements.
 
  4.8 No Liabilities. Neither Company nor any Subsidiary has any material
liabilities, obligations or commitments of any nature (whether absolute,
accrued, contingent or otherwise and whether matured or unmatured), including
without limitation, any liabilities due or to become due to any taxing
authority having jurisdiction over such entities, except (a) liabilities
reflected in, reserved against, or disclosed in the footnotes of, the balance
sheet of such Company or Subsidiary at March 31, 1996 included in the
Unaudited Financial
 
                                       7
<PAGE>
 
Statements, and (b) liabilities, obligations or commitments incurred since
March 31, 1996 in the ordinary course of such Company's or Subsidiary's
business or that are not material to the business of the Companies and the
Subsidiaries, taken as a whole.
 
  4.9 Absence of Certain Changes or Events. Since March 31, 1996, each of the
Companies and the Subsidiaries have conducted their respective businesses in
the ordinary course and, except pursuant to this Agreement and the
transactions contemplated hereby, there has not been any:
 
    (a) material adverse change in the financial condition, assets,
  liabilities, business, operations, results of operations or prospects of
  either Company or any Subsidiary or any other event or condition which in
  any one case or in the aggregate has materially and adversely affected
  either Company or any Subsidiary or any event or condition which it is
  reasonable to expect will individually or in the aggregate materially
  adversely affect the Companies and the Subsidiaries taken as a whole (any
  such event being herein referred to as a "Company Material Adverse
  Change");
 
    (b) declaration, waiver or payment of any dividend or other distribution
  or payment (whether in cash, shares or property) with respect to the share
  capital of either Company or any Subsidiary, or any redemption, purchase or
  other acquisition of any of the securities of any Company or Subsidiary, or
  any other payment to any shareholder of any Company or Subsidiary in its
  capacity as a shareholder;
 
    (c) issuance by either Company or any Subsidiary of, or commitment by any
  of them to issue, any share capital or obligations or any securities
  convertible into or exchangeable or exercisable for shares or other
  securities; or
 
    (d) indebtedness for borrowed money incurred by either Company or any
  Subsidiary or any commitment to incur indebtedness for borrowed money
  entered into by such Company or Subsidiary, or any loans made or agreed to
  be made to such Company or Subsidiary other than pursuant to commitments or
  credit facilities existing on March 31, 1996 and described in the Unaudited
  Financial Statements (or replacements thereof described in the Company
  Disclosure Letter).
 
  4.10 Insurance. Each Company and Subsidiary has in full force policies of
insurance issued by insurers of good repute insuring it and its properties and
business against such losses and risks, and in such amounts, as in its best
judgment, after advice from its insurance broker, are acceptable for the
nature and extent of such business and its resources. No Company or Subsidiary
is in default with respect to any material provision contained in any
insurance policy, and none has failed to give any notice or present any
existing claims it has under its insurance policies in a timely fashion.
 
  4.11 Employee Benefits and Pension Scheme.
 
    (a) Except as set forth in the Company Disclosure Letter, there are no
  agreements, arrangements, customs or practice (whether legally enforceable
  or not) in operation for the provision of, or payment or contributions
  towards, and no Company or Subsidiary has any liability or obligation to
  pay, any "relevant benefits" (as defined in Section 612 of the United
  Kingdom Income and Corporation Taxes Act 1988 (the "Taxes Act of 1988")),
  pensions, gratuities, allowances, lump sums or other like benefits on or
  after retirement or death or during periods of sickness, accident,
  incapacity or disablement for the benefit of any employee or former
  employee of either Company or of any Subsidiary (each, an "Employee") or
  such Employee's dependents, nor has any proposal been announced or promise
  made to establish any such agreement, arrangement or practice.

  Scheme (the "Company's Scheme"), including deeds of alteration, (ii) the
  current explanatory booklet issued to members of the Company's Scheme,
  (iii) all announcements to members of the Company's Scheme (or to Employees
  concerning the Company's Scheme) other than announcements to members of the
  Company's Scheme generally which have been fully
 
                                       8

  incorporated into the documents referred to in paragraph (d)(i) and (ii),

  Companies or a Subsidiary, and current salary and (vii) schedules of
  benefit structures indicating the relevant benefits provided or to be
  provided for Employees under the Company's Scheme in respect of all
  different categories of membership.
 
    (c) To the best knowledge of the Companies, the pension arrangements of
  each Company and Subsidiary, including without limitation, the Company's
  Scheme (collectively, the "Pension Arrangements"), have, at all times, been
  administered in all material respects in accordance with all applicable
  laws, rules and regulations.
 
    (d) To the best knowledge of the Companies, no discretion or power has
  been exercised under the Company's Scheme in respect of the Employees to at
  any time provide benefits in excess of those specifically provided for in
  the Company's Scheme.
 
    (e) No undertaking or assurance (whether or not constituting a legal
  binding commitment) has been given to any Employee about the continuation
  of the Company's Scheme or any alteration to or exception from its terms or
  the increase or improvement of benefits.
 
    (f) There are not, at the date of this Agreement, any outstanding
  contributions due to or under any Pension Arrangement, or that may become
  due to or under any Pension Arrangement with respect to any period prior to
  the Closing, from any Company or Subsidiary or any Employee or former
  Employee, except with respect to any such outstanding contributions that
  have been reserved against in the Financial Statements or that have
  occurred in the ordinary course of business since April 1, 1996.
 
    (g) The Company's Scheme is exempt approved (within the meaning of
  Section 592(1) of the Taxes Act of 1988) and is contracted out (for the
  purposes of the Pension Schemes Act 1993) and, to the best knowledge of the
  Companies, there are not facts or circumstances which may cause the
  withdrawal of approval by the Inland Revenue or cancellation of the
  contracted out status by the Occupational Pensions Board.
 
    (h) In respect of any of the Employees: there are no Actions in progress,
  pending or, to the best knowledge of the Companies, threatened against the
  Company's Scheme, any of the Companies or Subsidiaries or any of their
  trustees; and, to the best knowledge of the Companies, there are no
  investigations, inquiries, complaints or disciplinary proceedings by or
  before any government body or the Pensions Ombudsman concerning the
  Company's Scheme and none are pending or threatened.

  applicable laws in relation to the trusts, powers and provisions of each
  such Pension Arrangement and all regulations, orders, contracts,
  agreements, licenses or obligations of whatsoever nature, including without
  limitation, requirements of the United Kingdom Inland Revenue or the
  Occupational Pensions Board and of trust law, which affect each such
  Pension Arrangement or its operation; and all exercises or purported
  exercises of powers or discretions in relation to each such Pension
  Arrangement, including without limitation, the power of amendment, have
  been in all material respects proper and valid exercises of those powers or
  discretions.

  4.12 Material Contracts and Other Agreements. The Company Disclosure Letter
discloses (a) all agreements or contracts whether or not fully performed
pursuant to which either Company or any Subsidiary has since July 1, 1995
acquired or disposed of any business or assets exceeding (Pounds)75,000 in
value, other than sales of inventory or contracts with suppliers, each in the
ordinary course of business; (b) all agreements containing covenants not to
compete on the part of either Company or any Subsidiary or otherwise
restricting the ability of such Company or Subsidiary in any material way to
engage in its business; (c) all material notes, mortgages, indentures, letters
of credit, guarantees, performance bonds and other obligations and agreements
and other instruments for or relating to any lending or borrowing (including
assumed debt) entered into by either Company or any Subsidiary or pursuant to
which any properties or assets of any Company or Subsidiary are pledged or
mortgaged as collateral; and (d) all agreements to which any of the Companies
or Subsidiaries is a party containing provisions restricting or providing
exclusive rights with respect to the development, manufacture or marketing of
products which, after the Closing, would be applicable to the business or
products of the Buyer or Buyer's Subsidiary (as defined in Section 5.2) by
reason of the transactions contemplated by this Agreement.
 
  4.13 Suppliers and Customers. The Companies have delivered to Buyer a list
which accurately sets forth (a) the ten (10) largest suppliers of the
Companies and the Subsidiaries (considered as a whole) for the nine months
ended March 31, 1996 (the "Large Suppliers"), (b) the amount of all payments
made to each Large Supplier for such fiscal period, (c) the ten (10) largest
customers or groups of related customers of the Companies and the Subsidiaries
(considered as a whole) for the nine months ended March 31, 1996 (the "Large
Customers") and (d) the amount of all payments made by such Large Customers
for such fiscal period. No supplier is a sole source of supply of any good or
service used by the Companies or by any Subsidiary. None of the Large
Suppliers or Large Customers has canceled or otherwise terminated, or
threatened in writing, by notice to any Company or Subsidiary, to cancel or
otherwise terminate, its relationship with either Company or with any
Subsidiary or, since March 31, 1996, decreased materially, or threatened to
decrease or limit materially, its services, supplies or materials to either
Company or any Subsidiary or its usage or purchase of the products or services
of such Company or Subsidiary, which, in any case, would result in a Company
Material Adverse Change.
 
  4.14 Real Property. The Company Disclosure Letter sets forth all freehold
and leasehold real property of the Companies. All such freehold and leasehold
real property is collectively referred to herein as the "Real Property." The
Real Property comprises all land and premises owned, occupied or used by, or
in the possession of, the Companies and Subsidiaries. The Companies have good
and marketable title to the freehold Real Property, and true and correct
copies of all leases concerning the leasehold Real Property have been
delivered to the Buyer. There is appurtenant to the Real Property each right
and easement necessary in all material respects for its existing and continued
use.
 
  4.15 Condition of the Real Property; Rights of Use; Liabilities.
 
    (a) Neither the Real Property nor any of its title deeds is subject to an
  encumbrance, agreement, obligation, condition, right, easement, exception,
  reservation, overriding interest (as defined in sub-section 70(1) of the
  Land Registration Act 1925) or other interest. There is no person in
  possession or occupation of, or who has or claims a right or interest of
  any kind in, the Real Property adversely to any Company's or Subsidiary's
  interest.
 
    (b) No Action concerning any Real Property is pending or, to the best
  knowledge of any Company or Subsidiary, threatened. To the best knowledge
  of each Company and Subsidiary, no matter exists which may give rise to a
  proceeding of that type. To the best knowledge of the Companies, there is
  no outstanding notice affecting the Real Property.
 
    (c) To the best knowledge of each Company and Subsidiary, there is no
  resolution or proposal for compulsory acquisition of the Real Property by a
  local or other authority.
 
    (d) Subject to the terms and conditions of the applicable leasehold
  agreements, where any Company or Subsidiary holds Real Property under a
  lease, tenancy or license, no person, including without limitation, the
  landlord or licensor, may bring the term to an end before the expiry of the
  lease, tenancy or license by
 
                                      10
<PAGE>
 
  effluxion of time (except by forfeiture). Subject to the terms and
  conditions of the applicable leasehold agreements, to the best knowledge of
  the Companies there is no matter which could (i) entitle or require a
  person, including without limitation, a landlord or licensor, to forfeit or
  enter on, or take possession of, or occupy, the Real Property, (ii)
  restrict or terminate the Company's or Subsidiary's continued and
  uninterrupted possession or occupation of the Real Property or (iii)
  prevent or restrict the Real Property's development for which planning
  permission has been or is expected to be obtained. No rent or fee payable
  in respect of any of the Real Property is, as of the date hereof, being
  reviewed except where such reviews could not reasonably be expected to
  result in rent increases exceeding (Pounds)150,000 annually, in the
  aggregate. No person, including without limitation, a landlord or licensor,
  has elected to waive an exemption from payment by any Company or Subsidiary
  of value added tax in respect of a payment made under the lease, tenancy or
  license.
 
  4.16 Compliance with Laws. The Companies and the Subsidiaries are in
compliance with applicable laws, statutes, ordinances, rules and regulations,
orders or other requirements, including without limitation, applicable
franchise, building, planning, health, environmental, sanitation, safety,
employment relations and other laws, ordinances or regulations, other than
violations, if any, which, individually or in the aggregate, could not
reasonably be expected to have a Company Material Adverse Effect. Neither
Company nor any Subsidiary has received any notice from any person asserting a
present or past failure by either Company or any Subsidiary to comply in any
material respect with such laws, statutes, ordinances, rules, regulations,
orders or other requirements.
 
  4.17 Licenses and Permits. Each Company and Subsidiary has all material
governmental or regulatory licenses, permits and authorizations (all of which
are in full force and effect) reasonably necessary to conduct its business as
it is now being conducted, except for such governmental or regulatory
licenses, permits and authorizations the absence of which could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect, and none of such governmental or regulatory licenses, permits
and authorizations will be impaired as a result of the transactions
contemplated by this Agreement, except in any case that could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. No Company or Subsidiary has received any notice to the effect
that, or otherwise been advised that, it is not in compliance with, or that it
is in violation of, any such governmental or regulatory licenses, permits and
authorizations in a manner that could reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect, and, to
the best knowledge of each Company and Subsidiary, there are no currently
existing circumstances that are likely to result in a failure of any Company
or Subsidiary to comply with, or in a violation by any Company or Subsidiary
of, any such governmental or regulatory licenses, permits or authorizations
that could reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect.
 
  4.18 Title to Assets. The Companies and the Subsidiaries have good and
marketable title to all of the owned tangible personal property used in the
conduct of their businesses, free and clear of all Encumbrances, except for
assets disposed of in the ordinary course of business. Each Company and each
Subsidiary has good and valid leasehold title to all leased tangible personal
property leased by it from third parties, free and clear of all Encumbrances,
except for imperfections which individually or in the aggregate could not
reasonably be expected to cause a Company Material Adverse Effect, and subject
to the rights of the lessor in and to such tangible personal property as is
subject to hire, leasing or rental agreements.
 
  4.19 Inventory. The value at which the inventory of each Company and
Subsidiary is carried on each Company's consolidated balance sheet for the
fiscal year ended June 30, 1995 (the "Consolidated Balance Sheet") and each
Company's consolidated balance sheet for the quarter ended March 31, 1996 (the
"March Balance Sheet"), as included in the Financial Statements, reflects the
customary inventory valuation policy of each Company and its Subsidiaries and
is in accordance with SSAP and the Companies Act 1985. Since March 31, 1996,
the Companies and the Subsidiaries have in all material respects continued to
replenish their inventory in the ordinary course of business consistent with
past practice, and have not made any material change in their inventory
policies or procedures.

  provision was made therein for deferred taxation in accordance with SSAP,

  course of trading after the relevant Accounting Date.
 
    (d) No Company or Subsidiary is aware of any circumstance which will or
  may, whether by lapse of time or the issue of any notice of assessment or
  otherwise, give rise to any dispute with any relevant taxation authority in
  relation to its liability or accountability for taxation, any claim made by
  it, any relief, deduction or allowance afforded to it, or in relation to
  the status or character of each Company and Subsidiary (whether as to its

  group) under or for the purpose of any provision of any legislation
  relating to taxation.

  from all payments made, or treated as made, to its employees or former
  employees, and in all material respects accounted to the Inland Revenue for
  all tax so deducted and for all tax chargeable on benefits provided for its
  Employees or former Employees.
 
    (f) Each Company and Subsidiary is not nor will it become liable in any
  material respect to pay or make reimbursement or indemnity in respect of
  any taxation (or amounts corresponding thereto) in consequence of the
  failure by any person (other than either Company or any Subsidiary (the
  "Group")) to discharge that taxation within any specified period or
  otherwise, where such taxation relates to a profit, income or gain,
  transaction, event, omission or circumstance arising, occurring or deemed
  to arise or occur (whether wholly or party) prior to closing.
 
    (g) Each Company and Subsidiary has not since the relevant Accounting
  Date incurred nor has it become liable to incur after that date any
  material expenditure which will not be wholly deductible in computing its
  taxable profits, except for expenditure on the acquisition of an asset to
  be held otherwise than as stock-in-trade.

  ended on March 31, 1996 has been a close company within the meaning of
  Sections 414 and 415 of the Taxes Act of 1988, no apportionment within
  Sections 423-430 of the Taxes Act of 1988 and Schedule 19 to the Taxes Act
  of 1988 has ever been made or threatened against any Company or Subsidiary
  nor are there circumstances under
 
                                      12

  received or agreed to make or receive any material surrender relating to
  group relief or the benefit of advance corporation tax otherwise than to or
  from another company in the Group.
 
    (j) Except solely with respect to profit or gain accruing to ETE by
  reason of the sale of the US Shares hereunder, the execution or completion
  of this Agreement will not result in any profit or gain being deemed to
  accrue to any Company or Subsidiary for taxation purposes.
 
    (k) Each Company and Subsidiary has not in the six (6) years ended on the
  date of this Agreement carried out or been engaged in any material
  transaction or arrangement in respect of which there may be substituted for
  the actual consideration given or received by any Company or Subsidiary a
  different consideration for any taxation purposes.
 
    (l) No Company or Subsidiary nor any other person has made any claim for

  assets.
 
    (m) Each Company and Subsidiary has duly registered and is a taxable

  arrangement involving the relevant Company or Subsidiary.
 
    (q) In this subsection 4.21, "taxation" shall mean all forms of taxation,
  dues, duties, imposts, levies and rates of the United Kingdom or any other
  jurisdiction whenever and wheresoever charged, imposed or deducted together

all requisite corporate power and authority to own, operate and lease its
properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each

whole (a "Buyer Material Adverse Effect"). True and complete copies of the
Certificate of Incorporation and the By-Laws of Buyer have been delivered to
the Shareholders.

incorporation, with all
 
                                      16
<PAGE>
 
requisite corporate power and authority to own, operate and lease its
properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed could
reasonably be expected to have, individually or in the aggregate, a Buyer
Material Adverse Effect. All of the issued shares of capital stock of such
Subsidiary have been duly and validly authorized and issued, are fully paid
and non-assessable, and are owned directly by Buyer, free and clear of any and
all Encumbrances. Except with respect to its ownership of Buyer's Subsidiary,
its ownership of the capital stock of PMT CVD Partners, Inc. and its limited
partnership interest in PMT CVD Partners, L.P., Buyer does not own, directly
or indirectly, any stock, partnership interest, joint venture interest or
other security, investment or interest in any other corporation, organization,
partnership, limited liability company or entity. As used in this Article V,
references to "Buyer" shall include Buyer's Subsidiary, except to the extent
the context requires otherwise.
 
  5.3 Capital Stock. The authorized capital stock of Buyer consists in its
entirety of Fifty Million (50,000,000) shares of Buyer's Common Stock, of
which, as of the date hereof, 8,692,065 are issued and outstanding, and Twenty

voting trusts or other agreements, arrangements or understandings with respect
to the voting of the capital stock of Buyer. Except as set forth in the Buyer
Disclosure Letter, there are no preemptive rights, registration rights,
subscriptions, options, warrants, rights, convertible securities or other
agreements or commitments of any character relating to the issued or unissued
capital stock or other securities of Buyer and there are no outstanding
contractual obligations of Buyer to repurchase, redeem or otherwise acquire or
sell, issue or otherwise transfer any shares of capital stock thereof.

issued as contemplated hereby at the Closing, will be validly issued, fully
paid and non-assessable, will not be subject to any preemptive or other
similar rights and will be delivered to each Shareholder free and clear of all
Encumbrances, and each Shareholder will acquire good and marketable title to
the Buyer Shares acquired by such Shareholder, subject to any transfer

being issued pursuant to an available exemption from registration under the
Securities Act of 1933, as amended, provided by Regulation S promulgated

delivery and performance by Buyer of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by its Board of
Directors. Upon approval by Buyer's shareholders of the issuance of the Buyer
Shares to the Shareholders pursuant hereto, no other action on the part of
Buyer will be necessary to authorize the execution and delivery of this
Agreement by Buyer or the performance by Buyer of its obligations hereunder.
This Agreement has been duly executed and delivered by Buyer, and is a legal,
valid and binding obligation of Buyer, enforceable against Buyer in accordance
with its terms, except to the extent that its enforceability may be limited by
applicable bankruptcy, insolvency, reorganization or other laws affecting
creditors' rights generally or by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at
law). Each other agreement to be executed in connection with this Agreement on
or prior to the Closing Date will be duly executed and delivered by Buyer, and
will constitute a legal, valid and binding obligation of Buyer, enforceable
against it in accordance with its respective terms, subject to applicable
bankruptcy, insolvency, moratorium, reorganization, or similar laws affecting
creditors' rights generally and subject to general equitable principles
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).
 
  5.6 No Violations or Consents. The execution, delivery and performance of

the creation of any Encumbrance on any property or asset of Buyer pursuant to
any provision of any charter or by-law, indenture, mortgage, lien, lease,
agreement, contract, instrument, order, judgment, ordinance, regulation or
decree to which Buyer is subject or by which Buyer or any of its property or
assets is bound, or (d) result in a loss or adverse modification of any
license, permit, certificate, franchise or contract granted to or otherwise
held by Buyer which, in any such case described in clauses (a) through (d),

documents were filed with the Commission, the SEC Filings complied as to form
and content, in all material respects, with the requirements of the Securities
Act and the Exchange Act, as the case may be, and the rules and regulations
promulgated thereunder, and did not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. The financial statements of Buyer
included in the SEC Filings ("Buyer's Financial Statements") were prepared in
accordance with generally accepted accounting principles ("GAAP"),
consistently applied, and (except as may be indicated therein or in the notes
thereto) present fairly the consolidated financial position, results of
operations and cash flows of Buyer as of the dates and for the periods
indicated (subject, in the case of unaudited interim consolidated financial
statements, to normal recurring year-end adjustments and any other adjustments
described therein). Except as set forth in Buyer's Financial Statements, Buyer
has no liabilities, contingent or otherwise, other than (i) liabilities
incurred in the ordinary course of business subsequent to March 31, 1996, (ii)
obligations under real and personal property leases disclosed in Buyer's
Financial Statements, and (iii) obligations incurred in the ordinary course of
business and not required under GAAP to be reflected in Buyer's Financial

Buyer, threatened against Buyer that could be reasonably expected to
materially and adversely affect Buyer's consummation of the transactions
contemplated by this Agreement. None of the assets or property of Buyer is
subject to any order, judgment, injunction, writ or decree, which could
reasonably be expected to have, individually or in the aggregate, a Buyer
Material Adverse Effect.

any of the share capital of any Company or Subsidiary, to invest any funds in

other transaction involves a stock sale, a tender offer, exchange offer,
merger, consolidation or other business combination, or for the acquisition of
a substantial portion of the assets of any Company or Subsidiary (an
"Acquisition Proposal"). The Company and each Shareholder agree to immediately
communicate to the Buyer the identity of such other party and the initial
terms of any proposal it may receive from any other person or entity in
respect of an Acquisition Proposal.
 
  6.4 Proxy Statement and Meeting of Buyer's Shareholders.
 
    (a) As soon as reasonably practicable following the date hereof, Buyer
  shall prepare and file with the Commission, and, within ten (10) business

  Proxy Statement with respect to a meeting of Buyer's shareholders to
  consider and vote,
 
                                      25
<PAGE>
 
  among other things, upon this Agreement and the transactions contemplated
  hereby, including without limitation, Buyer's purchase of the US Shares and
  ET Shares and the issuance of the Buyer Shares in connection therewith.
  Each Company, Subsidiary and Shareholder agrees to assist and cooperate
  with the Buyer in the preparation of the Proxy Statement with respect to
  information therein concerning any such Company, Subsidiary or Shareholder.
 
    (b) The Buyer, on the one hand, and each Company and Subsidiary and the
  Majority Shareholder, on the other hand, hereby represents, warrants and
  agrees with the other that the Proxy Statement will not, at the time the
  Proxy Statement is mailed, and at the date of the meeting of the
  shareholders of the Buyer held to approve the matters described therein,
  contain any untrue statement of a material fact or omit to state any
  material fact required to be stated therein or necessary to make the
  statements therein, in light of the circumstances under which they are
  made, not misleading, or to correct any statement made in any earlier
  communication with respect to the solicitation of any proxy or approval of
  the transactions contemplated by this Agreement in connection with which
  the Proxy Statement shall be mailed, except that no representation or
  warranty is being made by either with respect to information supplied by
  the other for inclusion in the Proxy Statement. The Buyer further
  represents, warrants and agrees that the Proxy Statement will comply as to
  form in all material respects with the provisions of the Exchange Act. The
  letter to shareholders, notice of meeting, proxy statement and form of
  proxy, or any information statement filed under the Exchange Act, as the
  case may be, that may be provided to shareholders of the Buyer in
  connection with the transactions contemplated by this Agreement (including
  any supplements), and any schedules required to be filed with the
  Commission in connection therewith, as from time to time amended or
  supplemented, are collectively referred to as the "Proxy Statement."
 
    (c) Buyer shall take all actions necessary in accordance with the
  California Corporations Code and the bylaws of Buyer to duly call, give
  notice of, convene and hold a meeting of its shareholders within forty-five
  (45) calendar days after the mailing of the Proxy Statement to approve the
  transactions contemplated by this Agreement.
 
  6.5 Indemnification by Buyer.
 
    (a) Buyer agrees, upon and subject to the occurrence of the Closing, to
  indemnify the Companies and the Shareholders against and hold the Companies
  and each Shareholder harmless from any and all claims, obligations, costs
  and expenses, including without limitation, reasonable attorneys' fees and
  expenses, and liabilities of and damages thereto arising out of the
  material breach of any representation, warranty, covenant or agreement of
  Buyer contained in Sections 5.3 (Capital Stock), 5.4 (Buyer Shares),
  5.5 (Authority) and 6.4(b) (Proxy Statement matters) hereof (the "Surviving
  Buyer Warranties"). Buyer agrees to similarly indemnify the Majority
  Shareholder and Nigel Wheeler against and hold them harmless from any such
  claims, obligations, costs and expenses arising by reason that either such
  person becomes an officer and/or director of Buyer upon or after the
  Closing and based upon any alleged act, omission or misconduct of Buyer, or
  its officers, directors or other agents, prior to the Closing to the same
  extent as all other officers and directors of Buyer.
 
    (b) The indemnified parties agree to give Buyer prompt written notice of
  any claim, assertion, event or proceeding by or in respect of a third party
  of which they have knowledge concerning any liability or damage as to which
  they may request indemnification hereunder, provided that the failure to
  give such notice shall not impair the rights of the indemnified parties
  hereunder or otherwise if and to the extent that the Buyer is not
  prejudiced thereby. Buyer shall have the right to direct, through counsel
  of its own choosing, the defense or settlement of any such claim or
  proceeding (provided that Buyer shall have first acknowledged its
  indemnification obligations hereunder specifically in respect of such claim
  or proceeding) at its own expense, which counsel shall be reasonably
  satisfactory to the indemnified party or parties. If Buyer elects to assume
  the defense of any such claim or proceeding, the indemnified party or
  parties may participate in such defense, but in such case the expenses of
  the indemnified party or parties incurred in connection with such
  participation shall be paid by the indemnified party or parties, unless (i)
  the indemnified party or parties have legal defenses available to them
  which are different than those available
 
                                      26
<PAGE>
 
  to the indemnifying party such that representation by counsel of Buyer's
  choosing would be inappropriate, or (ii) the indemnifying party agrees to
  pay such expenses, then in either such case such expenses shall be paid by
  the indemnifying party. Such expenses shall be paid as and when incurred.
  The indemnified party or parties shall cooperate with Buyer in the defense
  or settlement of any such claim, assertion, event or proceeding. If Buyer
  elects to direct the defense of any such claim or proceeding, the
  indemnified party or parties shall not pay, or permit to be paid, any part
  of any claim or demand arising from such asserted liability, unless Buyer
  consents in writing to such payment or unless Buyer withdraws from the
  defense of such asserted liability, or unless a final judgment from which
  no appeal may be taken by or on behalf of Buyer is entered against such
  indemnified party for such liability. If Buyer shall fail to defend, or if,
  after commencing or undertaking any such defense, Buyer fails to prosecute
  or withdraws from such defense, the indemnified party or parties shall have
  the right to undertake the defense or settlement thereof at Buyer's
  expense.
 
  6.6 Indemnification by the Shareholders.
 
  (a) Each Shareholder agrees, severally and not jointly, upon and subject to
the occurrence of the Closing, to indemnify Buyer against and hold Buyer
harmless from any and all claims, obligations, costs and expenses, including
without limitation, reasonable attorneys' fees and expenses and liabilities of
and damages thereto arising out of any material breach of any representation,
warranty, covenant or agreement of such Shareholder contained in Article III
hereof and, with respect solely to the Majority Shareholder, Sections 4.3
(Share Capital; Title to ET Shares), 4.4 (Authority), and 6.4(b) (Proxy
Statement matters) hereof (the "Shareholder Surviving Warranties").
 
  (b) Buyer agrees to give the Shareholders prompt written notice of any
claim, assertion, event or proceeding by or in respect of a third party of
which it has knowledge concerning any Loss as to which it may request
indemnification hereunder, provided that the failure to give such notice shall
not impair the rights of the Buyer hereunder or otherwise to the extent that
the Shareholders are not prejudiced thereby. The Shareholders shall have the
right to direct, through counsel of their own choosing, the defense or
settlement of any such claim or proceeding (provided that the Shareholders
shall have first acknowledged their indemnification obligations hereunder
specifically in respect of such claim or proceeding) at their own expense,
which counsel shall be reasonably satisfactory to Buyer. If the Shareholders
elect to assume the defense of any such claim or proceeding, Buyer may
participate in such defense, but in such case the expenses of Buyer incurred
in connection with such participation shall be paid by Buyer, unless (i) the
indemnified party or parties have legal defenses available to them which are
different than those available to the indemnifying party such that
representation by counsel of Buyer's choosing would be inappropriate, or (ii)
the indemnifying party agrees to pay such expenses, then in either such case
such expenses shall be paid by the indemnifying party. Such expenses shall be
paid as and when incurred. Buyer shall cooperate with the Shareholders in the
defense or settlement of any such claim, assertion, event or proceeding. If
the Shareholders elect to direct the defense of any such claim or proceeding,
Buyer shall not pay, or permit to be paid, any part of any claim or demand
arising from such asserted Loss, unless the Shareholders consent in writing to
such payment or unless the Shareholders withdraw from the defense of such
asserted Loss, or unless a final judgment from which no appeal may be taken by
or on behalf of the Shareholders is entered against Buyer for such Loss. If
the Shareholders shall fail to defend, or if, after commencing or undertaking
any such defense, the Shareholders fail to prosecute or withdraws from such
defense, Buyer shall have the right to undertake the defense or settlement
thereof at the Shareholders' expense.
 
  6.7 General Indemnification Provisions. If the indemnifying party is
controlling the defense of a claim, the indemnifying party will not, without
the prior written consent of the indemnified party or parties, enter into any
settlement of such claim which could reasonably be expected to lead to
liability or create any financial or other obligation on the part of the
indemnified party or parties. If the indemnified party or parties are
controlling the defense of a claim, the indemnified party or parties will not
enter into any settlement of such claim without the consent of the
indemnifying party, which consent shall not be unreasonably withheld. The
indemnifying party shall advance amounts to the indemnified party or parties
then payable by the indemnifying party upon notice to the indemnifying party
and upon the indemnified party or parties entering into an agreement to repay
amounts
 
                                      27
<PAGE>
 
advanced that it is ultimately determined not to be entitled to. The
controlling party shall deliver, or cause to be delivered, to the other party
or parties copies of all correspondence, pleadings, motions, briefs, appeals
or other written statements relating to or submitted in connection with the
defense of any such claim and timely notices of, and the right to participate
in (as observer), any hearing or other court proceeding relating to such
claim.
 
  6.8 Best Efforts. Upon the terms and subject to the conditions herein
provided, Buyer, each Company and each Shareholder agrees to use its
reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done, all things necessary, proper or advisable to consummate the
transactions contemplated by this Agreement including (a) to lift or rescind
any injunction or restraining order or other order adversely affecting the
ability of the parties to consummate the transactions contemplated hereby and
(b) to fulfill all conditions on its part to be fulfilled under this
Agreement. In case at any time after the Closing Date any further action is
reasonably necessary or desirable to carry out the purposes of this Agreement,
the proper officers or directors of each party or the proper persons to this
Agreement shall take all such reasonably necessary action, including without
limitation, the delivery by each Shareholder to Buyer of a proxy to vote the
ET Shares in favor of this Agreement and the transactions contemplated hereby,
if so requested by Buyer. No party hereto will take any action for the purpose
of delaying, impairing or impeding the receipt of any required consent,
authorization, order or approval or the making of any required filing. Each
Company and Shareholder, on the one hand, and the Buyer, on the other hand,
shall give prompt notice to the other of (i) the occurrence, or failure to
occur, of any event which occurrence or failure would be likely to cause any
of its representations or warranties contained in this Agreement to be untrue
or inaccurate in any material respect any time from the date hereof to the
Closing Date and (ii) any material failure by it to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder, and each shall use all reasonable efforts to remedy such failure.
In addition, each shall give prompt notice to the other of any material
developments involving its operations or activities.
 
  6.9 Consents. The Buyer, each Company and each Shareholder will use its
reasonable best efforts to obtain all necessary waivers, consents and
approvals of all third parties and governmental authorities necessary to the
consummation of the transactions contemplated by this Agreement.
 
  6.10 No Transfer. Each Shareholder agrees that such Shareholder will not,
directly or indirectly, transfer, sell, assign, pledge, hypothecate, encumber
or otherwise dispose of any shares of either Company's share capital which
such Shareholder owns on and after the date hereof; provided, however, that
any Shareholder may transfer a portion of such shares (subject to his rights
and obligations hereunder with respect to such shares) to one or more trusts
established for the benefit of members of his family or established for
charitable purposes, provided that such trusts become a party hereto and
become otherwise bound hereby with respect to such transferred shares. ETE
agrees that it will not, directly or indirectly, transfer, sell, assign,
pledge, hypothecate, encumber or otherwise dispose of any of the US Shares.
 
  6.11 Environmental Investigations. Buyer shall conduct such environmental
investigations and reviews with respect to the Real Properties of the
Companies, including without limitation, Phase I investigations, as it shall
deem appropriate, in its sole discretion.
 
  6.12 Delivery of Financial Statements and Other Documents. Until the Closing
Date, each Company, on the one hand, and the Buyer, on the other hand, shall
deliver to the other:
 
    (a) as soon as practicable, but in any event within thirty (30) days
  after the end of each month, and within forty-five (45) days after the end
  of each quarter (with respect to the first three quarters of the applicable
  fiscal year) and within 60 days after the end of the last fiscal quarter,
  its unaudited consolidated profit and loss account, consolidated balance
  sheet and consolidated cash flow statement for such month or quarter, as
  the case may be, and for the fiscal year-to-date. Buyer's independent
  accountants, Ernst & Young, shall have reviewed all quarterly financial
  statements submitted by Buyer in compliance with the foregoing covenant;
 
    (b) as soon as practicable, but in any event within five (5) days of its
  receipt thereof, copies of any management letters and other correspondence
  of its independent auditors;
 
                                      28
<PAGE>
 
    (c) prompt notice of any material defaults under any material contracts
  and of any litigation;
 
    (d) monthly updates to the backlog descriptions described in Section 4.20
  and 5.19, as applicable. Each such update shall serve to supersede and
  replace in its entirety all previous backlog descriptions, provided that
  such updated descriptions shall, thereafter, be subject to the
  representations and warranties set forth in Sections 4.20 and 5.19, as
  applicable;
 
    (e) as soon as practicable, all other information requested by the other,
  where such information is readily available and may be reduced to written
  form.
 
  6.13 Additional Payments at Closing. The Buyer agrees that, upon the Closing
and the purchase of the ET Shares and US Shares by Buyer hereunder, the Buyer
shall pay to Christopher D. Dobson the cash amount of US$500,000 pursuant to
the Noncompetition Agreement (the "Dobson Noncompetition Fee") and shall
deliver to the Companies (in such respective amounts as the Majority
Shareholder shall direct) the following aggregate amounts and property as
contributions to capital:
 
    (a) at the discretion of the Board of Directors of ET and ETE, the cash
  sum of approximately US$1,500,000, the precise amount of which shall be
  specified by the Majority Shareholder prior to the Closing as the amount
  which, when added to the cash amount paid by Buyer for the US Shares, as
  specified in Section 1.3, represents the U.S. Dollar equivalent (the
  "Employee Bonus Amount") of One Pound Sterling for each day that all
  employees of the Companies and the Subsidiaries as of the Closing shall
  have been continuously employed by such Company or Subsidiary, as
  applicable, as of the Closing (such that the price paid for the US Shares,
  together with the capital contribution pursuant to this clause (a), shall
  be equal to the Employee Bonus Amount);
 
    (b) a cash amount, the precise amount of which shall be specified by the
  Majority Shareholder prior to the Closing, calculated to result in an
  after-tax bonus payment (assuming the highest marginal income tax rates) to
  Nigel Wheeler of approximately Six Hundred Thousand Dollars (US$600,000)
  (such full pre-tax amount being referred to as the "Wheeler Bonus"), it
  being understood and agreed that Mr. Wheeler will take all appropriate
  action to minimize his actual income tax obligations in respect of the
  Wheeler Bonus and that the actual after-tax portion of such bonus may
  accordingly exceed US$600,000; and
 
    (c) the cash sum of US$7,000,000 (the "Dobson Negotiation Fee").
 
    The Companies agree to pay or deliver, or cause the Subsidiaries to pay
  or deliver, the following aggregate sums or consideration (subject to any
  applicable withholdings required by law) to the indicated persons at the
  indicated times.
 
      (i) to each employee of any Company or Subsidiary as of the Closing,
    a bonus for past services rendered in an amount equal to One Pound
    Sterling for each day that such employee shall have been continuously
    employed by such Company or Subsidiary, as applicable, as of the
    Closing, to be paid as soon as practicable after the Closing;
 
      (ii) to Nigel Wheeler for past services rendered, the Wheeler Bonus,
    to be paid at the Closing; and
 
      (iii) to Christopher D. Dobson, the Dobson Negotiation Fee, to be
    paid at the Closing.

    (a) At and following the Closing, the Buyer shall cause the Companies and
  Subsidiaries to, from and after the Closing, honor in accordance with their
  terms all existing employment arrangements with their respective directors,
  other officers and Employees, provided that such arrangements have been
  disclosed in accordance with the terms of this Agreement. Furthermore, the
  Buyer represents and warrants that it presently intends to cause the
  Companies and Subsidiaries to continue indefinitely to provide pension and
  welfare benefits to their Employees (considered as a group) which benefits
  are intended to be in the aggregate no less favorable than those currently
  provided by the Companies and Subsidiaries in the aggregate to such
  Employees. Nothing set forth above in this Section shall be deemed to
  constitute an amendment of any existing employee benefit plan, program or
  arrangement or to prevent the Buyer or any Company or any Subsidiary from
  making any change in any plan, program or arrangement, including any change
  required by law or deemed necessary or appropriate to comply with
  applicable law or regulation.
 
                                      29
<PAGE>
 
    (b) Sufficiently prior to the Closing to facilitate the satisfaction of
  the condition to Closing set forth in Section 7.2(f), the Buyer shall
  recommend to its Board of Directors and Compensation Committee thereof the
  grant, under the Buyer's Stock Option Plan, of options covering an
  aggregate of approximately 800,000 shares of Buyer's Common Stock to such
  employees of the Companies and Subsidiaries, and in such respective
  individual amounts, as shall be jointly determined by the Buyer and the
  Majority Shareholder prior to the Closing. Such recommended option grants
  shall otherwise be at prices and upon such terms as are customarily
  contained in options generally granted under the Stock Option Plan.
 
  6.15 Use of Company Information. Buyer agrees that it shall not file with
the Securities and Exchange Commission of the United States any disclosure
document, including but not limited to the Proxy Statement, any document
relating to the financing referred to in Section 7.3(g), any report or other
document filed by the Buyer under the Exchange Act or otherwise made public,
that includes the names of either of the Companies, the Shareholders or any
Affiliate or Associate thereof, without the prior written consent of the
Majority Shareholder, except solely as and to the extent that the Buyer is
advised by its legal counsel that the same is required by law to be so filed
(in which case the Buyer shall use its best efforts to provide to the Majority
Shareholder, as early as possible prior to such filing, a copy of the document
proposed to be so filed, and shall give the Majority Shareholder, as and to
the extent practicable, reasonable opportunity to review and reasonably modify
such proposed filing).

    (c) by Buyer, if there is a material breach of any of the representations
  and warranties of any Company or Shareholder, or if any Company or
  Shareholder fails to comply in any material respect with any of its
  respective covenants or agreements contained herein; or
 
    (d) by the Shareholders, if there is a material breach of any of the
  representations and warranties of Buyer, or if Buyer fails to comply in any
  material respect with any of its covenants or agreements contained herein.
 
  8.2 Termination Fee; Expenses. Upon a termination of this Agreement (except
solely a No-Fee Termination, as defined below) the Buyer shall pay to the
Companies (in such respective amounts as they jointly instruct the Buyer) an
aggregate fee of US$1,000,000 (the "Termination Fee"), and the Buyer shall
additionally pay to them all reasonable fees and expenses actually incurred by
them in connection with the transactions contemplated hereby, including all
reasonable legal, investment banking, accounting and other fees and expenses
(the "Reimbursable Expenses"). The Termination Fee shall be payable in
immediately available funds on the second business day following any
termination giving rise to the obligation to pay such Termination Fee, and the
Reimbursable Expenses shall be payable within ten business days following the
submission to Buyer of a statement and accounting therefor.
 
  "No-Fee Termination" shall mean the following:
 
    (a) Any termination by Buyer or the Shareholders by reason of the non-
  occurrence of the condition to Closing set forth in clause (a) of Section
  7.1 (limited to United Kingdom matters in the case of a termination by
  Buyer, and limited to United States matters in the case of a termination by
  the Shareholders) or by the Shareholders by reason of the non-occurrence of
  the condition to Closing set forth in Section 7.2(l);
 
    (b) Any termination by Buyer by reason of the non-occurrence of any
  condition to Closing set forth in clause (a), (b), (c), (d), (e), (f) or
  (h) of Section 7.3; provided that any such termination by Buyer shall not
  constitute a No-Fee Termination if such non-occurrence is the result of a
  Company Material Adverse Change after the date of this Agreement; or
 
    (c) Any termination by the Shareholders by reason of the non-occurrence
  of any condition to Closing set forth in Section 7.2 if such non-occurrence
  is the result of a Buyer Material Adverse Change after the date of this
  Agreement.

  8.3 Effect of Termination. Except as otherwise provided in Section 8.2, in
the event of the termination of this Agreement as provided in Section 8.1
above, this Agreement shall forthwith become void and there shall be no
liability on the part of any party hereto, provided that nothing in this
Section 8.3 shall relieve any party of liability for any intentional breach of
the purchase and sale covenants herein, or the covenant to use reasonable
efforts to satisfy all conditions to Closing, which breach results in a
termination of this Agreement. Notwithstanding the foregoing, the covenant set
forth in Section 8.6 shall survive any termination of this Agreement for a
period of one year.
 
  8.4 Amendment. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions herein, provided that any such waiver of or failure to insist on
strict compliance with any such representation, warranty, agreement or
condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party.
 
  8.6 Conduct Following Termination. Following any termination of this
Agreement, neither Buyer nor its representatives, on the one hand, nor any
Company or Subsidiary nor any of their respective representatives nor the

the best of its knowledge" or any substantially equivalent phrase is used in

other hand, it shall mean both the actual knowledge of any such individual
person and, in the case of a corporation, the actual knowledge of each
executive officer thereof (including specifically the Majority Shareholder
with respect to each Company), and such knowledge as any such person, director

  9.6 Entire Agreement. This Agreement, the Letter Agreement dated May 2, 1996
and the Mutual Non-Disclosure Agreement dated December 19, 1995, as amended by
that certain letter dated May 22, 1996 to ET's counsel from counsel to the
Buyer, constitute the entire agreement among the parties and supersede all
other prior agreements and understandings, both written and oral, among the
parties, or any of them, with respect to the subject matter hereof or thereof.
 
  9.7 Conveyance Taxes. The Buyer agrees to assume liability for and to hold
the Shareholders harmless against any sales, use, transfer, stamp, stock
transfer, real property transfer or gains, and value added taxes, any
transfer, registration, recording or other fees (including without limitation,
any stamp duties), and any similar taxes incurred as a result of the
transactions contemplated hereby, other than capital gains taxes imposed upon
the Shareholders by virtue of the disposal of the ET Shares or with respect to
a higher rate of taxes due on any pre-Closing dividends due by reason of the
transactions permitted by Section 9.8 hereof, as to which the Shareholders
agree severally and not jointly to assume liability for and to hold Buyer and
the Companies harmless against.
 
  9.8 Company Pre-Closing Dividends. The Companies may, prior to the Closing,
declare and pay cash dividends to the Shareholders up to an amount permitted
by law but not exceeding the net cash payment specified in Section 1.4(a)
hereof, in which case the parties agree that:
 
  (a) Buyer shall, immediately prior to the Closing, loan to the Companies an
amount equal to the sum of such dividends, plus all taxes required to be paid
by the Companies in connection with the payment of such dividends (the
"Dividend Taxes"), in order to fund the payment of such dividends immediately
prior to the Closing and the payment of the Dividend Taxes;
 
  (b) The cash portion of the Purchase Price payable to the Shareholders at
the Closing pursuant to Section 1.4 shall be reduced, prorata as to each
Shareholder, by an aggregate amount equal to such loan by the Buyer;
 
  (c) Immediately after the Closing, the indebtedness of the Companies to the
Buyer in respect of the loan referred to in clause (a) shall be forgiven by
the Buyer as a contribution to the capital of the Companies but subject to the
contingent obligation of the Companies to make the payments described in
clause (d) below; and
 
  (d) From time to time if and when the Companies are entitled to a credit for
the Dividend Taxes against other amounts due and payable for income taxes of
the Companies, then the Companies shall pay to the Shareholders (promptly
after such time as the Companies would have otherwise been required to pay to
the taxing authorities the amounts so reduced by such credit), prorata to each
Shareholder in the same proportion that the cash portion of the Purchase Price
was reduced under clause (b) above, the aggregate amount of such credit.
 
  9.9 Advance of Reimbursable Expenses. Within seven (7) days after
presentation to the Buyer by the Companies of invoices or other reasonable
evidence thereof, the Buyer shall advance to the Companies a sum equal to all
Reimbursable Expenses incurred by the Companies prior to the execution of this
Agreement in respect of amounts payable to third parties other than Hambrecht
& Quist, and excluding any internal charges or expenses of the Companies or
any Subsidiary. Such payments shall be considered an advance in respect of any
amounts ultimately owed by the Buyer to the Companies pursuant to Section 8.2
hereof and, if no amounts are ever owed by the Buyer to the Companies pursuant
to Section 8.2 hereof by reason of the occurrence of a No-Fee Termination of
this Agreement, the Companies shall, within seven (7) days following the
occurrence of such No-Fee Termination, refund to the Buyer all amounts
advanced to the Companies pursuant to this Section 9.9.
 
  9.10 Hold-back Agreement. Each of the Shareholders severally agrees that
such Shareholder will not offer, sell or contract to sell, or otherwise
dispose of, directly or indirectly, or announce an offering of any shares of
Buyer Common Stock beneficially owned by such Shareholder or any securities
convertible into, or exchangeable for, shares of Buyer Common Stock for a
period of 90 days following the Closing Date, without the prior written
consent of Salomon Brothers Inc, the lead investment banker engaged by the
Buyer in connection with the transaction described in Section 7.3(g).

  6. Compensation. Employer shall pay to Executive, as compensation for the
services agreed to be rendered by Executive hereunder, the following:
 
    (a) Base Salary. During the Employment Term, Employer shall pay to
  Executive a salary of $250,000 per annum payable in British pounds
  sterling; provided, that the amount of such base salary shall be reviewed
  and may be adjusted by Employer annually during the Employment Term in
  light of the conditions then existing and the services then being rendered
  by Executive, in which case Executive's base salary shall be such higher
  amount as may be determined by Employer (such annual base salary, as in
  effect from time to time, being referred to herein as the "Base Salary").
  The Base Salary shall be payable monthly at the exchange rate prevailing at
  the date of each monthly payment, less appropriate deductions for federal,
  state and local income taxes, FICA contributions and any other deductions
  required by law or authorized by Executive.
 
    (b) Annual Performance Bonus. In addition to the Base Salary, Executive
  shall be eligible to receive an annual performance bonus (the "Annual
  Bonus") for each year of service (or any part thereof in the event of
  termination of Executive's employment hereunder (other than a Termination
  Without Good Reason or a Termination for Cause), in which case any Annual
  Bonus shall be prorated for such partial year) during the Employment Term
  (each such year or any partial such year referred to as an "Annual Bonus
  Period"),

  to the maximum extent of eligibility permitted to executive officers, or if
  no such bonus is permitted, in such amount, if any, as may be determined by
  the Board in its discretion. Each Annual Bonus shall be payable in British
  pounds sterling at the exchange rate prevailing at the date of payment
  which shall be in accordance with Employer's normal annual bonus payment
  schedule, less appropriate deductions for federal, state, and local income
  taxes, FICA contributions and any other deductions required by law or

  Stock Option Plan, options to acquire 200,000 shares of Employer's common
  stock at an exercise price equal to the fair market value of the underlying
  shares of common stock on the date of such grant, 25% of which shall vest
  on each anniversary of the date of grant over a period of four years (the
  "Options), subject to Executive's continuous employment or consultancy with
  Employer pursuant hereto.
 
    (d) Payment of Additional Amount. Employer shall pay to Executive, for so
  long as Executive is not a resident of the United States, as additional
  payments, such amounts as may be necessary in order that every net payment
  of Executive's salary, bonus or other payment, after deducting or
  withholding for or on account of any present or future tax, assessment or
  other governmental charge imposed upon, or as a result of, such payment by
  the government of the United States or any state thereof or any political
  subdivision or taxing authority of or in the United States, will not be
  less than (x) the gross amount provided for herein, as may be adjusted by
  the Board of Directors pursuant hereto, then due and payable minus (y) the
  amount of income taxes payable by Executive or required to be deducted or
  withheld for or on account of any present or future tax, assessment or
  other governmental charge.

as is allowed under the policies of Employer to management generally,
Executive shall be entitled during each twelve-month period during the
Employment Term to twenty-four (24) days of vacation and all statutory bank
holidays of England, with full pay. The duration of such vacations and the
time or times when they shall be taken will be determined by Executive in
consultation with Employer.

  written notice of termination to Executive, which notice will specify the
  date of termination. Upon such termination, Executive will be released from
  any duties and obligations hereunder (except as set forth in Section 11)
  and Executive will be entitled to receive the payments prescribed by
  subsection 10(c)(i). "Disabled" as used in this Agreement means the
  inability of Executive substantially to perform his duties for a period of
  180 consecutive days or for a total of 180 days or more in any 360-day
  period as a result of a physical or mental illness, all as determined in

  the third anniversary of the date of this Agreement, in addition to any
  rights Executive may have with respect to payments, if any, pursuant to
  Section 6, Employer will pay to Executive the following compensation which
  when paid will be deemed to be paid in final settlement of any claims in
  connection with such termination Executive may have against Employer or any
  Affiliate of Employer, and after such payments are made, Employer and its
  Affiliates will have no liability or obligation of any kind to Executive in
  connection with such termination:
 
      (i) Payment Upon Termination Without Cause or For Good Reason. If a
    Termination Without Cause or a Termination For Good Reason has
    occurred, or if Executive becomes Disabled, Executive will be entitled
    to receive his Base Salary (at the rate of effect at the Effective Date
    of Termination) through the remainder of the Employment Term (which,
    for purposes of this Section 10(e)(i), shall not be less than one
    year), without setoff or reduction in respect of such amounts, if any,
    earned by Executive from other employment after the Effective Date of
    Termination either, at Executive's election, in a lump sum payment or
    in the same manner as paid prior to the Effective Date of Termination
    and Executive shall receive all the benefits to which he is entitled
    pursuant to clauses (a), (b) and (e) of Section 7 through the remainder
    of the Employment Term.
 
      (ii) Payment Upon Termination For Cause or Without Good Reason. If a
    Termination For Cause or a Termination Without Good Reason has
    occurred, Employer will pay to Executive his Base Salary (as in effect
    on the Effective Date of Termination) and other benefits, including
    accrued vacation pay, (without setoff or reduction in respect of such
    amounts) to which Executive is entitled pursuant to this Agreement
    through the Effective Date of Termination.
 
      (iii) Payment Upon Termination in the Event of Death. In the case of
    a termination of this Agreement upon Executive's death, Executive's

    effect on the date of death) through the end of the month in which the
    Effective Date of Termination occurs and other benefits including those
    specified in Section 7 hereof through the end of the month in which the
    Effective Date of Termination occurs and accrued vacation pay (all
    without setoff or reduction in respect of such amounts).
 
    (f) Effective Date of Termination. The "Effective Date of Termination" of
  Executive's employment will be: (i) in the case of a Termination Without
  Cause, on the date specified in a notice given by Employer to Executive or,
  if no date is specified, on the date such notice is given; (ii) in the case

<PAGE>
 
any Affiliate of Employer or any of their respective customers, suppliers,
landlords, licensors or licensees. Upon the expiration or termination of the
Employment Term, Executive will surrender and deliver to Employer all
documents and information of every kind relating to or connected with Employer
and its Affiliates and their respective businesses, customers, suppliers,
landlord, licensors and licensees. The foregoing confidential information
provisions shall not apply to information which: (i) is or becomes publicly
known through no wrongful act of the Executive; (ii) is rightfully received
from any third party without restriction and without breach by Executive of
this Employment Agreement; or (iii) is independently developed by Executive

competitor of Employer at any time. The provisions of this Section 11 shall
survive the expiration and/or termination of this Employment Agreement for a

  12. Non-Compete. During the Noncompetition Term (as defined below) Executive
will not directly or indirectly engage in competition with Employer by being
associated in any capacity (whether as employee, owner, consultant, agent or
otherwise) with any person or entity that sells or offers to sell any products
or services which are in the same line of business as the Business and which
directly compete in any area in the world where the Employer's products or
services are offered or sold by Employer. The foregoing sentence shall not
preclude the ownership by Executive of 10% or less of any class of security of
any issuer which is registered pursuant to the Securities Exchange Act of
1934, as amended, or which is listed on the London Stock Exchange. As used
herein, "Noncompetition Term" means the period of Executive's employment with
Employer and for such period after an Effective Date of Termination during
which Executive continues to receive any payments equal to his Base Salary
pursuant to subsection 10(e)(i) above.
 
  13. Arbitration. Any dispute or controversy arising out of or relating to
this Agreement or any claimed breach hereof shall be settled, at the request
of either party, by an arbitration proceeding conducted in accordance with the
rules of the American Arbitration Association ("AAA"), with the award
determined to be appropriate by the arbitrator therein to be final, non-
appealable and binding on the parties hereto, and with judgment upon such
award as is rendered in any such arbitration proceeding available for entry
and enforcement in any court having jurisdiction of the parties hereto. The
arbitrator shall be an impartial arbitrator qualified to serve in accordance
with the rules of the AAA and shall be reasonably acceptable to each of the
Employer and the Executive. If no such acceptable arbitrator is so appointed
within fifteen (15) days after the initial request for arbitration of such
disputed matter, each of the parties promptly shall designate a person
qualified to serve as an arbitrator in accordance with the rules of the AAA,
and the two persons so designated promptly shall select the arbitrator from
among those persons qualified to serve in accordance with the rules of the
AAA. The arbitration shall be held in the State of California in the United
States at the time of the initiation of any such proceedings, or in such other
place as may be agreed upon at the time by the parties. The expenses of the
arbitration proceeding shall be borne by Employer.
 
  14. Indemnification.
 
    (a) Employer shall indemnify Executive to the fullest extent permitted by
  the Articles of Incorporation and Bylaws of Employer as in effect on the
  date hereof (or if such Articles of Incorporation or Bylaws are amended to
  broaden such indemnification, then such broadened indemnification terms
  shall apply) against all costs, expenses, liabilities and losses
  (including, without limitation, attorneys' fees, judgments, penalties and
  amounts paid in settlement) reasonably incurred by Executive in connection
  with any action, suit or proceeding, whether civil, criminal,
  administrative or investigative in which Executive is made, or is
  threatened to be made, a party to or a witness in such action, suit or
  proceeding by reason of the fact that he is or was an officer, director,
  consultant, agent or Executive of the Employer or of any of Employer's
  Affiliates or is or was serving as an officer, consultant, director,
  member, Executive, trustee, agent or fiduciary of any other entity at the
  request of the Employer (a "Proceeding"). Employer shall maintain policies
  for insurance coverage of Executive to the fullest extent available to any
  other director or officer of Employer, which shall include director and
  officer insurance and insurance coverage relating to acts of Employer prior
  to the commencement of Executive's employment hereunder. Employer shall
  enter into an
 
                                      B-5
<PAGE>
 
  indemnification agreement with Executive to the same extent Employer has
  entered into such agreements with other executive officers of Employer.
 
    (b) The indemnification provided to Executive hereunder is in addition
  to, and not in lieu of, any additional indemnification to which he may be
  entitled pursuant to Employer's Articles of Incorporation or Bylaws, any
  insurance maintained by Employer from time to time providing coverage to
  Executive and other officers and directors of Employer, or any separate
  written agreement with Executive. The provisions of this Section 14 shall
  survive any termination of this Agreement.
 
  15. Amendment and Modification. This Agreement contains the entire agreement
between the parties with respect to the subject matter hereof. Such to
applicable law and upon the consent of the Board of Employer, this Agreement
may be amended, modified and supplemented by written agreement of Employer and
Executive with respect to any of the terms contained herein.
 
  16. Waiver of Compliance. Any failure of either party to comply with any
obligation, covenant, agreement or condition on its part contained herein may
be expressly waived in writing by the other party, but such waiver or failure
to insist upon strict compliance shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure. Whenever this Agreement
requires or permits consent by or on behalf of any party, such consent shall
be given in writing.

                    [FORM OF OPINION OF RIORDAN & MCKINZIE]
 
                                      , 1996
 
 
The Shareholders parties to that
 certain Share Purchase Agreement
 dated July   , 1996
 
    Re: Share Purchase Agreement
 
Ladies and Gentlemen:
 
  This firm has acted as counsel to Plasma & Materials Technologies, Inc., a
California corporation ("Buyer"), in connection with that certain Share
Purchase Agreement dated as of July    , 1996 (the "Share Purchase Agreement")
among Buyer, Electrotech Ltd., a corporation organized under the laws of
England ("ET"), Electrotech Equipments Ltd., a corporation organized under the
laws of England ("ETE," and sometimes collectively with ET, the "Companies"),
Christopher D. Dobson, an individual, F.S. Keeble, an individual, and K.N.K.
Willmott, as Managing Trustee of the Willmott Settlements (collectively, the
"Shareholders"). This opinion is delivered to you in compliance with Section
7.2(i) of the Share Purchase Agreement. Unless otherwise defined herein,
capitalized terms used herein shall have the meanings given to them in the
Share Purchase Agreement.
 
  In rendering this opinion, we have examined originals or copies, certified
or otherwise identified to our satisfaction, of such corporate records,
certificates of public officials, documents and other instruments as we have
deemed necessary or appropriate to enable us to express the opinions set forth
below. In our examination, we have assumed the authenticity of all documents
submitted to us as originals and the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies. In
rendering this opinion, when the facts were not independently established or
verified by us, we have relied upon certificates, statements, representations
and opinions of officers, other representatives of the Buyer, public officials
and others.
 
  This Opinion is subject to all matters contained or referred to in the Buyer
Disclosure Letter.
 
  We have investigated such questions of law as we have deemed relevant and
necessary in connection with rendering this opinion. We are attorneys duly
admitted and qualified to practice only in the State of California, and,
except as noted below in this paragraph, we are opining herein only as to the
effect on the subject transactions of United States federal law and the laws
of the State of California. With respect to all matters of the laws of England
addressed by the last sentence of paragraph 2 and by paragraphs 3 and 4, we
are, with your consent, opining in reliance on the opinion of Reynolds Porter
Chamberlain, a copy of which is attached hereto. We are not opining on, and
assume no responsibility as to the applicability of, or the effect on any of
the matters covered herein of, the laws of any other jurisdiction.
 
  Based on the foregoing and subject to the qualifications, exceptions and
limitations set forth herein, we are of the opinion that:
 
    1. To our best knowledge, the Buyer is a corporation duly organized,
  validly existing and in good standing under the laws of the State of
  California, has all corporate power and authority and all material
  governmental licenses, authorizations, consents and approvals required to
  carry on its business as now conducted and is duly qualified to do business
  as a foreign entity and is in good standing within such states of the
  United States of America where the character of the property owned or
  leased by it, or the nature of its activities, makes such qualification
  necessary, except where the failure to be so qualified could not reasonably
  be expected to have a Buyer Material Adverse Effect.
 
                                      C-1
<PAGE>
 
    2. The execution and delivery of the Share Purchase Agreement by the
  Buyer and the consummation of the transactions contemplated thereby have
  been duly authorized by the Board of Directors and shareholders of the
  Buyer. The Share Purchase Agreement has been duly executed and delivered by
  the Buyer and constitutes the valid and binding obligations of the Buyer,
  enforceable against it in accordance with its terms.
 
    3. The Buyer Shares issued to the Shareholders pursuant to the Share
  Purchase Agreement have been duly authorized, validly issued and are fully
  paid and non-assessable and were not issued in violation of any preemptive
  rights.
 
    4. To our best knowledge, the execution, delivery and performance of the
  Share Purchase Agreement and the consummation by the Buyer of the
  transactions contemplated thereby will not (a) contravene or constitute a
  default under or give rise to a right of termination, cancellation or
  acceleration of any right or obligation of the Buyer or to a loss of any
  benefit to which the Buyer is entitled under any provision of
  (i) applicable law or regulation, (ii) the Articles of Incorporation or
  Bylaws of the Buyer, or (iii) to the best of our knowledge, any agreement,
  contract, instrument, plan, lease, judgment, injunction, order, decree,
  award or other instrument binding upon the Buyer or (b) to our best
  knowledge, result in the creation or imposition of any Encumbrances on any
  asset of the Buyer, except for any such contravention, default,
  termination, cancellation, acceleration, loss or Encumbrance that could not
  reasonably be expected, individually or in the aggregate, to have a Buyer
  Material Adverse Effect.
 
    5. To our best knowledge, there are no claims, actions, proceedings or
  investigations pending or threatened involving or affecting the Buyer or
  any of its properties or assets before any court or governmental or
  regulatory authority or body in which an adverse determination could
  reasonably be expected to have a Buyer Material Adverse Effect or that in
  any manner challenges or seeks to prevent, enjoin, alter or materially
  delay any of the transactions contemplated by the Share Purchase Agreement.
  To our best knowledge, neither the Buyer nor any of its property or assets
  is subject to any order, judgment, injunction or decree that could
  reasonably be expected to have a Buyer Material Adverse Effect.
 
  The opinion expressed in paragraph 2 above is qualified to the extent that
the validity, binding nature or enforceability of any term of the Share
Purchase Agreement may be limited or otherwise affected by (a) applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
similar laws affecting creditors' rights generally, and (b) general principles
of equity, including (without limitation) concepts of materiality,
reasonableness, good faith and fair dealing, and the possible unavailability
of specific performance or injunctive relief (regardless of whether such
enforceability is considered in a proceeding in equity or at law).
Furthermore, such opinion is limited with respect to any indemnity provisions
contained in the Share Purchase Agreement to the extent that the enforcement
thereof may be limited by public policy considerations.
 
  This opinion letter is intended solely for your benefit in connection with
the transactions contemplated by the Share Purchase Agreement and may not be
relied upon by you for any other purpose, or relied upon by any other person
for any purpose without our prior written consent.
 
  Our liability in respect of the above opinion shall not in any event exceed
the sum of Fifteen Million Pounds Sterling ((Pounds)15,000,000) inclusive of
all costs, demands, expenses, consequential damages and interest, and any such
liability shall cease on the expiration of one year from the date of Closing.
 
                                          Very truly yours,
 
                                      C-2

                                                                      EXHIBIT D
 
                            REGISTRATION AGREEMENT
 
  THIS REGISTRATION AGREEMENT (this "Agreement") is made and entered into as
of         , 1996 by and between Plasma & Materials Technologies, Inc., a
California corporation (the "Company"), and Christopher D. Dobson, an
individual (the "Investor"). This Agreement is entered into pursuant to that
certain Share Purchase Agreement dated as of July 17, 1996 (the "Share
Purchase Agreement") by and among the Company, Electrotech Limited,
Electrotech Equipments Limited, the Investor and certain other parties.
 
  1. Definitions. For purposes of this Agreement:
 
    (a) The term "register," "registered," and "registration" refer to a
  registration effected by preparing and filing with the Securities and
  Exchange Commission (the "SEC") a registration statement or similar
  document in compliance with the Securities Act of 1933, as amended (the
  "Securities Act"), and the declaration or ordering of effectiveness of such
  registration statement or document; and
 
    (b) The term "Registrable Securities" means the             shares of the
  Company's Common Stock issued to the Investor pursuant to the Share
  Purchase Agreement, and any Common Stock of the Company issued as (or
  issuable upon the conversion or exercise of any warrant, right or other
  security which is issued as) a dividend or other distribution with respect
  to, or in exchange for or in replacement of, such Common Stock.
 
  2. Request for Registration.
 
    (a) If the Company shall receive at any time after the first anniversary
  of this Agreement, a written request from the Investor that the Company
  file a registration statement under the Securities Act covering the
  registration of any Registrable Securities (provided that the aggregate
  amount of such Registrable Securities would exceed the amount specified in
  paragraph (e) of Rule 144 under the Securities Act), then the Company shall
  file as soon as practicable, and in any event within 90 days of the receipt
  of such request, a registration statement under the Securities Act covering
  all Registrable Securities which the Investor so requests to be registered.
 
    (b) The Company is obligated to effect only three such registrations
  pursuant to this Section 2; provided, however, that the Company shall not
  be obligated to effect any such registration if the Company has, within the
  six months preceding the date of receipt of the request for such
  registration, already effected one such registration.
 
    (c) Notwithstanding the foregoing, if the Company shall furnish to the
  Investor a certificate signed by the President or Chief Executive Officer
  of the Company stating that, in the good faith judgment of the Board of
  Directors of the Company, it would be seriously detrimental to the Company
  and its shareholders for such registration statement to be filed and it is
  therefore essential to defer the filing of such registration statement, the
  Company shall have the right to defer such filing for a period of not more
  than an additional 120 days after receipt of the request of the Investor
  referred to in Section 2(a) above; provided, however, that the Company may
  not utilize this right more than once in any 12-month period.
 
  3. Company Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Investor) any of its
stock or other securities under the Securities Act in connection with the
public offering, on or after the first anniversary of this Agreement, of such
securities solely for cash (other than a registration relating solely to the
sale of securities to participants in a Company stock option, purchase or
similar benefit plan or an SEC Rule 145 transaction), the Company shall, at
such time, promptly give the Investor written notice of such registration.
Upon the written request of the Investor given within 30 days after the
effectiveness of such notice by the Company, the Company shall, subject to the
provisions of Section 8, cause to be registered under the Securities Act all
of the Registrable Securities that the Investor has requested to be
registered. In the event the Investor determines not to include any or all of
the Registrable Securities held by the Investor in any such registration, the
Investor shall continue to have the right to include such Registrable
Securities in any subsequent registration, pursuant to the terms of this
Section 3.
 
                                      D-1
<PAGE>
 
  4. Obligations of the Company. Whenever required under this Agreement to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:
 
    (a) Prepare and file with the SEC a registration statement with respect
  to such Registrable Securities and use its best efforts to cause such
  registration statement to become effective, and, upon the request of the
  Investor, keep such registration statement effective for up to 120 days.
 
    (b) Prepare and file with the SEC such amendments and supplements to such
  registration statement and the prospectus used in connection with such
  registration statement as may be necessary to comply with the provisions of
  the Securities Act with respect to the disposition of all securities
  covered by such registration statement.
 
    (c) Furnish to the Investor such numbers of copies of a prospectus,
  including a preliminary prospectus, in conformity with the requirements of
  the Securities Act, and such other documents as he may reasonably request
  in order to facilitate the disposition of his Registrable Securities.
 
    (d) Use its best efforts to register and qualify the securities covered
  by such registration statement under such other securities or Blue Sky laws
  of such jurisdictions as shall be reasonably requested by the Investor,
  provided that the Company shall not be required in connection therewith or
  as a condition thereto to qualify to do business or to file a general
  consent to service of process in any such states or jurisdictions.
 
    (e) In the event of any underwritten public offering, enter into and
  perform its obligations under an underwriting agreement, in usual and
  customary form, with the managing underwriter of such offering. The
  Investor shall also enter into and perform its obligations under such an
  agreement.
 
    (f) Notify the Investor at any time when a prospectus relating thereto is
  required to be delivered under the Securities Act of the happening of any
  event as a result of which the prospectus included in such registration
  statement, as then in effect, includes an untrue statement of a material
  fact or omits to state a material fact required to be stated therein or
  necessary to make the statements therein not misleading in the light of the
  circumstances then existing.
 
    (g) Furnish, at the request of the Investor, on the date that such
  Registrable Securities are delivered to the underwriters for sale in
  connection with a registration pursuant to this Agreement, if such
  securities are being sold through underwriters, or, if such securities are
  not being sold through underwriters, on the date that the registration
  statement with respect to such securities becomes effective, (i) an
  opinion, dated such date, of the counsel representing the Company for the
  purposes of such registration, in form and substance as is customarily
  given to underwriters in an underwritten public offering, addressed to the
  underwriters, if any, and to the Investor, and (ii) a letter dated such
  date, from the independent certified public accountants of the Company, in
  form and substance as is customarily given by independent certified public
  accountants to underwriters in an underwritten public offering, addressed
  to the underwriters, if any, and to the Investor.
 
  5. Furnish Information. It shall be a condition precedent to the obligations
of the Company to take any action pursuant to this Agreement that the Investor
shall furnish to the Company such information regarding himself, the
Registrable Securities held by him, and the intended method of disposition of
such securities as shall be required to effect the registration of the
Registrable Securities.
 
  6. Expenses of Demand Registrations. All expenses other than underwriting
discounts and commissions incurred by the Company in connection with
registrations, filings or qualifications pursuant to Section 2, including
(without limitation) all registration, filing and qualification fees,
printers' and accounting fees, and fees and disbursements of counsel for the
Company, shall be borne by the Company.
 
  7. Expenses of Company Registration. The Company shall bear and pay all
expenses incurred by the Company in connection with any registration, filing
or qualification of Registrable Securities with respect to the registrations
pursuant to Section 3, including (without limitation) all registration, filing
and qualification fees, printers' and accounting fees and fees and
disbursements of counsel for the Company, but excluding underwriting discounts
and commissions relating to Registrable Securities.
 
                                      D-2
<PAGE>
 
  8. Underwriting Requirements. In connection with any offering involving an
underwriting of shares being issued by the Company, the Company shall not be
required under Section 3 to include any of the Investor's securities in such
underwriting unless the Investor accepts the terms of the underwriting as
agreed upon between the Company and the underwriters selected by the Company,
and then only in such quantity as will not, in the opinion of the
underwriters, jeopardize the success of the offering by the Company. If the
total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be
required to include in the offering only that number of such securities,
including Registrable Securities, which the underwriters believe will not
jeopardize the success of the offering (the securities so included to be
apportioned pro rata among the selling shareholders according to the total
amount of securities entitled to be included therein owned by each selling
shareholder or in such other proportions as shall mutually be agreed to by
such selling shareholders), provided that any shares being sold by the
Investor in exercising a demand registration right granted in Section 2, or by
any other shareholder exercising a demand registration right similar to that
granted in Section 2, shall not be excluded from such offering.
 
  9. Delay of Registration. The Investor shall not have any right to obtain or
seek an injunction restraining or otherwise delaying any registration as the
result of any controversy that might arise with respect to the interpretation
or implementation of this Agreement.
 
  10. Indemnification. In the event any Registrable Securities are included in
a registration statement under this Agreement:
 
    (a) To the extent permitted by law, the Company will indemnify and hold
  harmless the Investor, any underwriter (as defined in the Securities Act)
  for the Investor and each person, if any, who controls such Investor or
  underwriter within the meaning of the Securities Act or the Securities
  Exchange Act of 1934, as amended (the "Exchange Act") against any losses,
  claims, damages or liabilities (joint or several) to which they may become
  subject under the Securities Act, the Exchange Act or other federal or
  state law, insofar as such losses, claims, damages or liabilities (or
  actions in respect thereof) arise out of or are based upon any of the
  following statements, omissions or violations (collectively a "violation"):
  (i) any untrue statement or alleged untrue statement of a material fact
  contained in such registration statement, including any preliminary
  prospectus or final prospectus contained therein or any amendments or
  supplements thereto, (ii) the omission or alleged omission to state therein
  a material fact required to be stated therein, or necessary to make the
  statements therein not misleading, or (iii) any violation or alleged
  violation by the Company of the Securities Act, the Exchange Act, any state
  securities law or any Rule or regulation promulgated under the Securities
  Act, the Exchange Act or any state securities law; and, within 30 days
  after the Company receives a written request containing a description in
  reasonable detail of the expenses incurred, the Company will advance to the
  Investor and each underwriter or controlling person any legal or other
  expenses reasonably incurred by them in connection with investigating or
  defending any such loss, claim, damage, liability or action, whether prior
  to or after final disposition of any claim or action (unless there has been
  a final determination that such Investor, underwriter or controlling person
  is not entitled to be indemnified for such expenses); provided, that at the
  time of such advance, such Investor, underwriter or controlling person
  shall agree to repay the amounts advanced if it is ultimately determined
  that he or she is not entitled to be indemnified pursuant to the terms of
  this Agreement; provided, however, that the indemnity agreement contained
  in this Section 10(a) shall not apply to amounts paid in settlement of any
  such loss, claim, damage, liability or action if such settlement is
  effected without the consent of the Company (which consent shall not be
  unreasonably withheld), nor shall the Company be liable in any such case
  for any such loss, claim, damage, liability or action to the extent that it
  arises out of or is based upon a violation which occurs in reliance upon
  and in conformity with written information furnished expressly for use in
  connection with such registration by any such Investor, underwriter or
  controlling person.
 
    (b) To the extent permitted by law, the Investor will indemnify and hold
  harmless the Company, each of its directors, each of its officers who have
  signed the registration statement, each person, if any, who controls the
  Company within the meaning of the Securities Act, and any underwriter,
  against any losses,
 
                                      D-3
<PAGE>
 
  claims, damages or liabilities (joint or several) to which the Company or
  any such director, officer, controlling person, or underwriter may become
  subject, under the Securities Act, the Exchange Act or other federal or
  state law, insofar as such losses, claims, damages or liabilities (or
  actions in respect thereto) arise out of or are based upon any violation,
  in each case to the extent (and only to the extent) that such violation
  occurs in reliance upon and in conformity with written information
  furnished by the Investor expressly for use in connection with such
  registration; and the Investor will reimburse as incurred any legal or
  other expenses reasonably incurred by the Company or any such director,
  officer, controlling person or underwriter in connection with investigating
  or defending any such loss, claim, damage, liability, or action; provided,
  however, that the indemnity agreement contained in this Section 10(b) shall
  not apply to amounts paid in settlement of any such loss, claim, damage,
  liability or action if such settlement is effected without the consent of
  the Investor, which consent shall not be unreasonably withheld; provided,
  that, in no event shall any indemnity under this Section 10(b) exceed the
  net proceeds from the offering received by the Investor.
 
    (c) Promptly after receipt by an indemnified party under this Section 10
  of notice of the commencement of any action (including any governmental
  action), such indemnified party will, if a claim in respect thereof is to
  be made against any indemnifying party under this Section 10, deliver to
  the indemnifying party a written notice of the commencement thereof and the
  indemnifying party shall have the right to participate in, and, to the
  extent the indemnifying party so desires, jointly with any other
  indemnifying party similarly noticed, to assume the defense thereof with
  counsel mutually satisfactory to the parties; provided, however, that an
  indemnified party (together with all other indemnified parties that may be
  represented without conflict by one counsel) shall have the right to retain
  its own counsel, with the fees and expenses to be paid by the indemnifying
  party, if representation of such indemnified party by the counsel retained
  by the indemnifying party would be inappropriate due to actual or potential
  differing interests between such indemnified party and any other party
  represented by such counsel in such proceeding. The failure to deliver
  written notice to the indemnifying party within a reasonable time of the
  commencement of any such action, if prejudicial to its ability to defend
  such action, shall relieve such indemnifying party of any liability to the
  indemnified party under this Section 10, but the omission so to deliver
  written notice to the indemnifying party will not relieve it of any
  liability that it may have to any indemnified party otherwise than under
  this Section 10.
 
    (d) The obligations of the Company and the Investor under this Section 10
  shall survive the completion of any offering of Registrable Securities in a
  registration statement under this Agreement, and otherwise.
 
    (e) If the indemnification provided for in this Section 10 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 a 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. Notwithstanding the foregoing, to the extent that the provisions
  on indemnification and contribution contained in the underwriting agreement
  entered into in connection with the underwritten public offering are in
  conflict with the foregoing provisions, the provisions in the underwriting
  agreement shall control.
 
  11. Termination of Registration Rights. The Company's obligations pursuant
to this Agreement shall terminate when the Investor can sell all of the
Registrable Securities pursuant to Rule 144 under the Securities Act during
any 90-day period.
 
                                      D-4

  13. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California, without regard to
principles of conflicts of laws.
 
  14. Entire Agreement. This Agreement is intended by the parties hereto as a
final expression of their agreement and intended to be a complete and
exclusive statement of the parties hereto in respect of the subject matter
contained herein.
 
  15. Notices. Unless otherwise provided, any notice required or permitted
under this Agreement shall be given in writing and shall be deemed effective
when given upon personal delivery to the party to be notified or, if sent by
telex or telecopier, upon receipt of the correct answer back, or three
business days after deposit with the United States Post Office, by registered
or certified mail, or upon delivery by Federal Express, DHL or similar
courier, in each case postage and delivery charges prepaid and addressed to
the party to be notified at the address indicated for such party on the
signature page hereof, or at such other address as such party may designate by
ten days' advance written notice to the other parties.
 
  IN WITNESS WHEREOF, the Company, each of the Investors and the Founder have

authorized, all as of the date first written above.

                           NONCOMPETITION AGREEMENT
 
  THIS NONCOMPETITION AGREEMENT ("Agreement") is made as of this      day of
         , 1996 between Plasma & Materials Technologies, Inc., a California
corporation ("Buyer"), and Christopher D. Dobson ("Shareholder").
 
                               R E C I T A L S :
 
  A. Pursuant to a Share Purchase Agreement dated as of July    , 1996 (the
"Acquisition Agreement") among Buyer, Shareholder, Electrotech Limited, a
corporation organized and existing under the laws of England ("ET"),
Electrotech Equipments Limited, a corporation organized and existing under the
laws of England ("ETE"; and sometimes collectively with ET, the "Companies")
and the other shareholders of the Companies, Buyer will be acquiring all of
the outstanding capital stock of the Companies and one subsidiary of ETE (the
"Acquisition").
 
  B. The Acquisition Agreement requires that Shareholder enter into a
noncompetition agreement upon the effectiveness of the Acquisition and that
the obligation of Buyer to consummate the Acquisition is conditioned upon the
Shareholder entering into such noncompetition agreement.
 
  C. The parties therefore desire to enter into this Agreement in order to
implement the requirements of the Acquisition Agreement and to confirm in
Buyer the good will of the business of the Companies and all of the benefits
to be derived therefrom.
 
                              A G R E E M E N T :
 
  THEREFORE, in consideration of the Acquisition, the consideration to be
received by Shareholder as a result of the Acquisition, the Noncompetition Fee
set forth in Section 1 hereof and the mutual covenants herein contained and
other consideration (the receipt and adequacy of which are hereby acknowledged
by Shareholder), the parties hereby agree as follows:
 
  1. In consideration of the noncompetition covenant of Shareholder hereunder,
the Buyer has paid to Shareholder the cash amount of Five Hundred Thousand
Dollars (US$500,000) (the "Noncompetition Fee") concurrent with the execution
of this Agreement.
 
  2. (a) During the term hereof, Shareholder shall not directly or indirectly
carry on or participate in any business in competition with the Business (as
hereinafter defined) as long as the Business is carried on by the Companies
(or Buyer, any subsidiary or controlled affiliate of Buyer or of the Companies
or any person, corporation, partnership, trust or other organization or entity
deriving title from Buyer or the Companies to the good will of the Business,
all of whom together with Buyer and the Companies are sometimes collectively
called the "Protected Entities"). "Business" means the semiconductor
manufacturing equipment development, production and marketing business of the
Companies as the same exists immediately prior to the Acquisition and as the
same is to be carried on by the Companies immediately after the Acquisition.
 
  This covenant shall extend throughout the following geographic areas:
 
    (i) The United Kingdom;
 
    (ii) The countries of the United States of America, France, Germany and
  Japan; and
 
    (iii) Each and every country and territory throughout the world in which
  either of the Companies or any of their subsidiaries does business
  immediately prior to the Acquisition.
 
                                      E-1
<PAGE>
 
    (b) The term "directly or indirectly carry on or participate in a
  business in competition with the Business" shall include Shareholder,
  directly or indirectly, doing any of the following listed acts:
 
      (i) carrying on or engaging in any such business as a principal, or
    on his own account, or solely or jointly with others as a director,
    officer, agent, employee, consultant or partner, or stockholder or
    limited partner owning (of record or beneficially, through a nominee or
    otherwise) more than ten percent (10%) of the stock of or equity
    interest in, or securities convertible into more than ten percent (10%)
    of the stock of or equity interest in, any corporation or limited
    partnership; or
 
      (ii) as agent or principal carrying on or engaging in any activities
    or negotiations with respect to the acquisition or the disposition of
    any such business; or
 
      (iii) lending credit or money for the purpose of establishing or
    operating any such business; or
 
      (iv) giving advice to any other person, firm, association or
    corporation engaging in any such business; or
 
      (v) lending or allowing his name or reputation to be used in any such
    business; or
 
      (vi) allowing his skill, knowledge or experience to be used in any
    such business.
 
    (c) The term of this covenant shall extend for a period of three (3)
  years commencing upon the effectiveness of the Acquisition.
 
    (d) It is the desired intent of the parties that the provisions of this
  Section 2 shall be enforced to the fullest extent permissible under the
  laws and public policies applied in each jurisdiction in which enforcement
  is sought. Accordingly, to the extent that the covenant hereunder shall be
  adjudicated to be invalid or unenforceable in any one such jurisdiction,
  this Section 2 shall be deemed amended to delete therefrom or reform the
  portion thus adjudicated to be invalid or unenforceable, such deletion or
  reformation to apply only with respect to the operation of this Section in
  the particular jurisdiction in which such adjudication is made.
 
  3. Upon breach of the covenant contained in Section 2, the Protected
Entities shall be entitled to injunctive relief, both pending litigation and
permanently, as a remedy at law would be inadequate and insufficient.
 
  4. The covenants of Shareholder hereunder shall be construed as and shall be
independent of the covenants, representations, warranties and obligations of
the Shareholder under the Acquisition Agreement or under any agreement or
instrument delivered pursuant to the Acquisition.
 
  5. (a) All notices required or desired to be given hereunder shall be in
writing and signed by the party so giving notice, and shall be effective when
personally delivered or deposited in the United States mail, as certified or
registered mail, return receipt requested, first class postage and fees
prepaid, addressed as set forth below. Any party may from time to time change
such party's address for giving notice by giving notice thereof in the manner

    (b) Should any party hereto retain counsel for the purpose of enforcing,
  or preventing the breach of, any provision hereof, including, but not
  limited to, by instituting any action or proceeding in court to enforce any
  provision hereof or to enjoin a breach of any provision hereof, or for a
  declaration of such party's rights or obligations hereunder, or for any
  other judicial remedy, then the prevailing party shall be entitled to be
  reimbursed by the losing party for all costs and expenses incurred thereby,
  including, but not limited to, attorneys' fees (including costs of appeal).

    (c) This Agreement shall inure to the benefit of Buyer, the Companies and
  their successors and assigns.
 
    (d) The failure by a Protected Entity to enforce any of its rights
  hereunder shall not be deemed to be a waiver of such rights, unless such
  waiver is in writing and signed by the waiving party, and in the case of
  any corporation, approved by its Board of Directors. Waiver of any one
  breach shall not be deemed to be a waiver of any other breach of the same
  or any other provision hereof. This Agreement can be amended only by a
  written agreement executed by each party hereto.
 
    (e) The validity of this Agreement, the construction of its terms and the
  determination of the rights and duties of the parties hereto shall be
  governed by the internal substantive laws of California.
 
    (f) All pronouns and any variations thereof shall be deemed to refer to
  the masculine, feminine, neuter, singular or plural as the identity of the
  person, persons, entity or entities may require.
 
    (g) This Agreement contains the sole and entire agreement and
  understanding of the parties with respect to the entire subject matter
  hereof and any and all prior discussions, negotiations, commitments,
  letters of intent, memoranda, writings and understandings related hereto
  are hereby superseded.
 
  IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

  Re: Share Purchase Agreement
 
Ladies and Gentlemen:
 
  This firm has acted as solicitors to Electrotech Ltd., a corporation
organized under the laws of England ("ET"), Electrotech Equipments Ltd., a
corporation organized under the laws of England ("ETE," and sometimes
collectively with ET, the "Companies"), Christopher D. Dobson, an individual,
F.S. Keeble, an individual, and K.N.K. Willmott, as Managing Trustee of the
Willmott Settlements (collectively, the "Shareholders"), in connection with
that certain Share Purchase Agreement dated as of July    , 1996 (the "Share
Purchase Agreement") among Plasma & Materials Technologies, Inc., a California
corporation ("Buyer"), the Companies and the Shareholders. This opinion is
delivered to you in compliance with Section 7.3(e) of the Share Purchase
Agreement. Unless otherwise defined herein, capitalized terms used herein
shall have the meanings given to them in the Share Purchase Agreement.
 
  In rendering this opinion, we have examined originals or copies, certified
or otherwise identified to our satisfaction, of such corporate records,
certificates of public officials, documents and other instruments as we have
deemed necessary or appropriate to enable us to express the opinions set forth
below. In our examination, we have assumed the authenticity of all documents
submitted to us as originals and the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies. In
rendering this opinion, when the facts were not independently established or
verified by us, we have relied upon certificates, statements, representations
and opinions of officers, other representatives of the Company, public
officials and others.
 
  This Opinion is subject to all matters contained or referred to in the
Shareholder Disclosure Letter and the Company Disclosure Letter.
 
  Based on the foregoing and subject to the qualifications, exceptions and
limitations set forth herein, we are of the opinion that:
 
    1. To our best knowledge, each Company and each Subsidiary thereof
  incorporated in the United Kingdom (a "U.K. Subsidiary") is a corporation
  duly organized, validly existing and in good standing under the laws of
  England and Wales, has all corporate power and authority and all material
  governmental licenses, authorizations, consents and approvals required to
  carry on its business as now conducted and is duly qualified to do business
  and is in good standing within the United Kingdom, except where the failure
  to be so qualified could not reasonably be expected to have a Company
  Material Adverse Effect.
 
                                      F-1
<PAGE>
 
    2. Save as specified in the Company Disclosure Letter and to our best
  knowledge, the shares of each of the Companies' outstanding capital stock
  have been duly authorized, validly issued and are fully paid and non-
  assessable and were not issued in violation of any preemptive rights. Such
  shares are owned of record and, to the best of our knowledge, beneficially
  and free of all Encumbrances, by the Shareholders and in the respective
  amounts set forth on Exhibit A to the Share Purchase Agreement. To the best
  of our knowledge, there are no outstanding subscriptions, options,
  warrants, rights, convertible or exchangeable securities or other
  agreements, commitments or contingent liabilities on the part of either
  Company to issue any additional shares of capital stock or any other equity
  securities.
 
    3. The execution and delivery of the Share Purchase Agreement by each
  Company and the consummation of the transactions contemplated thereby have
  been duly authorized by the Board of Directors of each Company. The Share
  Purchase Agreement has been duly executed and delivered by each Company and
  each Shareholder and so far as we are aware constitutes the valid and
  binding obligations of each Company and each Shareholder, enforceable so
  far as we are aware against each Company and each Shareholder in accordance
  with its terms.
 
    4. Pursuant to the Share Purchase Agreement and to our best knowledge,
  the Shareholders have transferred to the Buyer good and marketable title to
  all the issued share capital of the Companies, and ETE has transferred to
  the Buyer good and marketable title to all the issued share capital of ET-
  US, free and clear of all Encumbrances, assuming that Buyer purchased the
  same in good faith and without notice of any adverse claims.
 
    5. So far as we are aware, the execution, delivery and performance of the
  Share Purchase Agreement and the consummation by each Company and by each
  Shareholder of the transactions contemplated thereby will not (a)
  contravene or constitute a default under or give rise to a right of
  termination, cancellation or acceleration of any right or obligation of
  either Company or any U.K. Subsidiary or to a loss of any benefit to which
  such Company or such Subsidiary is entitled under any provision of (i)
  applicable law or regulation, (ii) the Memorandum and Articles of either
  Company or any U.K. Subsidiary or (iii) to the best of our knowledge, any
  agreement, contract, instrument, plan, lease, judgment, injunction, order,
  decree, award or other instrument binding upon either Company or any U.K.
  Subsidiary or (b) to the best of our knowledge, result in the creation or
  imposition of any Encumbrances on any asset of either Company or any U.K.
  Subsidiary, except for any such contravention, default, termination,
  cancellation, acceleration, loss or Encumbrance that could not reasonably
  be expected, individually or in the aggregate, to have a Company Material
  Adverse Effect.
 
    6. To the best of our knowledge, there are no claims, actions,
  proceedings or investigations pending or threatened involving or affecting
  either Company or any U.K. Subsidiary or any of their properties or assets,
  or any Shareholder, before any court or governmental or regulatory
  authority or body in which an adverse determination could reasonably be
  expected to have a Company Material Adverse Effect or that in any manner
  challenges or seeks to prevent, enjoin, alter or materially delay any of
  the transactions contemplated by the Share Purchase Agreement. To the best
  of our knowledge, neither Company nor any U.K. Subsidiary nor any property
  or assets or any of them nor any Shareholder is subject to any order,
  judgment, injunction or decree that could reasonably be expected to have a
  Company Material Adverse Effect.
 
  The opinion expressed in paragraph 3 above is qualified to the extent that
the validity, binding nature or enforceability of any term of the Share
Purchase Agreement may be limited or otherwise affected by (a) applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
similar laws affecting creditors' rights generally, and (b) general principles
of equity, including (without limitation) concepts of materiality,
reasonableness, good faith and fair dealing, and the possible unavailability
of specific performance or injunctive relief (regardless of whether such
enforceability is considered in a proceeding in equity or at law).
Furthermore, such opinion is limited with respect to any indemnity provisions
contained in the Share Purchase Agreement to the extent that the enforcement
thereof may be limited by public policy considerations.

  This opinion letter is intended solely for your benefit in connection with
the transactions contemplated by the Share Purchase Agreement and may not be
relied upon by you for any other purpose, or relied upon by any other person
for any purpose without our prior written consent.
 
  Our liability in respect of the above opinion shall not in any event exceed
the sum of Fifteen Million Pounds Sterling ((Pounds)15,000,000) inclusive of
all costs, demands, expenses, consequential damages and interest, and any such
liability shall cease on the expiration of one year from the date of Closing.

Board of Directors
Plasma & Materials Technologies, Inc.

Chatsworth, California 91311
 
Dear Sirs:
 
  You have requested our opinion, as investment bankers, as to the fairness,
from a financial point of view, to Plasma & Materials Technologies, Inc. (the
"Company") of the consideration to be paid by the Company in connection with
the proposed acquisition (the "Acquisition") of Electrotech Ltd. ("ET") and
Electrotech Equipments Ltd. ("ETE" and collectively with ET, "Electrotech")
pursuant to the Share Purchase Agreement dated as of July 17, 1996 (the "Share
Purchase Agreement"), among the Company, ET, ETE, and the shareholders named
therein. Under the Share Purchase Agreement, the Company will acquire 100% of
the outstanding capital stock of Electrotech for an aggregate of $75,000,000
(reduced by certain amounts to be otherwise paid by the Company pursuant to the
Share Purchase Agreement) and 5,600,000 shares of the Company's Common Stock.
 
  In arriving at our opinion, we have reviewed the Share Purchase Agreement and
its related exhibits. We have also reviewed certain publicly available business
and financial information relating to the Company, as well as certain other
information, including financial projections, provided to us by the Company and
Electrotech. We have discussed the past and current operations and financial
condition and prospects of the Company and Electrotech with members of senior
management of the Company and Electrotech, respectively. We have also
considered such other information, financial studies, analyses, investigations
and financial, economic, market and trading criteria which we deemed relevant.
 
  In arriving at our opinion, we have assumed and relied on the accuracy and
completeness of the information reviewed by us for the purpose of this opinion,
and we have not assumed any responsibility for independent verification of such
information or for any independent evaluation or appraisal of the assets of the
Company or Electrotech. With respect to the Company's and Electrotech's
financial projections, we have assumed that they have been reasonably prepared
on bases reflecting the best currently available estimates and judgments of the
Company's or Electrotech's, as the case may be, management as to the future
financial performance of the Company or Electrotech, as the case may be, and we
express no opinion with respect to such forecasts or the assumptions on which
they are based. We have also assumed that the proposed Acquisition would be
accounted for as a purchase in accordance with generally accepted accounting
principles. Our opinion is necessarily based upon business, market, economic
and other conditions as they exist on, and can be evaluated as of, the date of
this letter and does not address the Company's underlying business decision to
effect the proposed Acquisition or constitute a recommendation to any holder of
the Company's Common Stock as to how such holder should

[LETTERHEAD OF SALOMON BROTHERS INC]
 
vote with respect to the proposed Acquisition. Our opinion as expressed below
does not imply any conclusion as to the likely trading range for the Company's
Common Stock following the consummation of the proposed Acquisition, which may
vary depending on, among other factors, changes in interest rates, dividend
rates, market conditions, general economic conditions and other factors that
generally influence the price of securities.
 
  We have acted as financial advisor to the Board of Directors of the Company
in connection with the proposed Acquisition and will receive a fee for our
services, a portion of which has been paid, a portion of which is payable upon
the initial filing of the Company's proxy statement and the remaining portion
of which is payable upon the consummation of the proposed Acquisition. We have
from time to time provided significant investment banking and financial
advisory services to the Company, including, but not limited to, participating
as managing underwriter in the initial public offering of the Company's Common
Stock in August 1995, for which we received substantial compensation. We will
also act as placement agent with respect to the Company's proposed offering of
convertible subordinated debt securities to be issued to partially finance the
proposed Acquisition. In the ordinary course of our business, we actively trade
the equity securities of the Company for our own account and for the accounts
of customers and, accordingly, may at any time hold a long or short position in
such securities.
 
  Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the consideration to be paid by the Company in connection with the
proposed Acquisition is fair, from a financial point of view, to the Company.
 
Very truly yours,
 
SALOMON BROTHERS INC

                     PLASMA & MATERIALS TECHNOLOGIES, INC.
                            1991 STOCK OPTION PLAN
 
  Section 1. Description of Plan. This is the 1991 Stock Option Plan (the
"Plan") of Plasma & Materials Technologies, Inc., a California corporation
(the "Company"). Under the Plan, employees, directors, consultants and
advisors of the Company or any of its Subsidiaries, to be selected as set
forth below, may be granted options ("Options") to purchase shares of the
Common Stock of the Company ("Common Stock"). For purposes of the Plan, the
term "Subsidiary" means any corporation 50% or more of the voting stock of
which is owned by the Company or by a Subsidiary of the Company. It is
intended that the Options under the Plan will either qualify for treatment as
incentive stock options under Section 422 of the Internal Revenue Code of
1986, as amended (the "Code") and be designated Incentive Stock Options, or
not qualify for such treatment and be designated Nonqualified Stock Options.
 
  Section 2. Purpose of this Plan. The purpose of the Plan and of granting
options to employees, directors, consultants and advisors is to further the
growth, development and financial success of the Company and its subsidiaries
by providing additional incentives to such persons by assisting them in
acquiring shares of Common Stock and to benefit directly from the Company's
growth, development and financial success.
 
  Section 3. Eligibility. The persons who shall be eligible to receive grants
of Options under the Plan shall be the employees, directors, consultants and
advisors of the Company or any of its Subsidiaries. A person who holds an
Option is herein referred to as a "Participant." More than one Option may be
granted to any one Participant. Notwithstanding the foregoing, no Incentive
Stock Option may be granted to any person who then owns stock possessing more
than 10% of the total combined voting power of all classes of stock of the
Company or of a Subsidiary unless (a) the Option Price (as hereinafter
defined) is at least 110% of the fair market value of the Common Stock on the
date of grant, and (b) the termination date of such Option is not later than
five years after the date such Option is granted. For this purpose, a person's
stock ownership is determined using the constructive ownership rules contained
in Code Section 424(d).
 
  Only employees of the Company or a Subsidiary may be granted Incentive Stock
Options under the Plan. The exercise of an Incentive Stock Option will not
qualify for favorable income tax treatment unless the Participant remains an
employee of the Company or a Subsidiary at all times during the period
beginning on the date of the grant of the Incentive Stock Option and ending on
the date three months before the date of the exercise of the Incentive Stock
Option. For this purpose, a Participant who is on a leave of absence that
exceeds ninety days will be considered to have terminated his employment on
the ninety-first day of the leave of absence, unless the Participant's rights
to reemployment are guaranteed by statute or contract. However, a Participant
will not be considered to have incurred a termination of employment because of
a transfer of employment between the Company and a Subsidiary (or vice versa).
 
  The aggregate fair market value (determined as of the time an Option is
granted) of the Common Stock for which any Participant may be granted
Incentive Stock Options first exercisable in any calendar year under the Plan
and any other incentive stock option plans (which qualify under Section 422 of
the Code) of the Company or any Subsidiary shall not exceed $100,000.
 
  Section 4. Administration. This Plan shall be administered by the Board of
Directors of the Company or a committee thereof (in either case, the "Board").
The Board shall be composed of individuals who qualify under Rule 16b-3
promulgated by the Securities and Exchange Commission and under Code Section
162(m).
 
  The Board is authorized and empowered to administer the Plan and, subject to
the Plan, (a) to select the Participants, to specify the number of shares of
Common Stock with respect to which Options are granted to each such
Participant, to specify the Option Price (as hereinafter defined) and the
terms of Options, and in general
 
                                      C-1
<PAGE>
 
to grant Options; (b) to determine, subject to the limits of Section 3 hereof,
whether Options will be Incentive Stock Options or Nonqualified Stock Options;
(c) to determine the dates upon which Options shall be granted and to provide
for the terms and conditions of the Options in a manner consistent with this
Plan, which terms and conditions need not be identical as to the various
Options granted; (d) to interpret the Plan; (e) to prescribe, amend and
rescind rules relating to the Plan; and (f) to determine the rights and
obligations of Participants under the Plan. The interpretation and
construction by the Board of any provision of the Plan or of any Option
granted thereunder shall be final. No member of the Board shall be liable for
any action or determination made in good faith with respect to the Plan or any
Option granted under it.
 
  Section 5. Shares Subject to the Plan. The number of shares of Common Stock
which may be purchased pursuant to the exercise of Options granted under the
Plan shall be 900,000 shares. Such number shall in any event be adjusted to
reflect all stock splits, stock dividends or similar capital changes. Upon the
expiration or termination for any reason of an outstanding Option which shall
not have been exercised in full, any shares of Common Stock then remaining
unissued which shall have been reserved for issuance upon such exercise shall
again become available for the granting of additional Options under the Plan.
The maximum number of shares that may be issued to any Participant shall be
500,000. For this purpose, an Option granted to a Participant shall be
continued to be outstanding despite its cancellation, and the repricing of an
Option shall be treated as the grant of a new option.
 
  Section 6. Option Price. The purchase price per share (the "Option Price")
of the shares of Common Stock underlying each Option shall be determined in
each case by the Board with respect to each specific Option but shall not be
less than the fair market value of such shares on the date of grant. In the
event that the Company acquires another entity, the Board may authorize the
issuance of Options ("Substitute Options") to the individuals performing
services for the acquired entity in substitution of stock options previously
granted to those individuals in connection with their performance of services
for such entity upon such terms and conditions as the Board shall determine,
taking into account the conditions of Code Section 424(a) in the case of a
Substitute Option that is intended to be an Incentive Stock Option.
 
  Section 7. Exercise of Options. Subject to all other provisions of the Plan,
each Option shall be exercisable for the full number of shares of Common Stock
subject thereto, or any part thereof, in five equal cumulative annual
installments commencing one year after the date of grant (provided the
Participant is employed by the Company at the time of vesting), or in such
other installments and at such other intervals as the Board may in any
specific case or cases otherwise specifically determine in granting such
Option. Each Option shall terminate and expire, and shall no longer be subject
to exercise, ten years after the date of grant thereof, or at such earlier
date as the Board may otherwise specifically determine in granting such
Option. The Option shall be exercised by the Participant by giving written
notice to the Company specifying the number of full shares to be purchased and
accompanied by payment of the full purchase price therefor in cash, by check
or in such other form of lawful consideration (including promissory notes or
shares of Common Stock then held by the Participant) as the Board may approve
from time to time.
 
  Section 8. Option. Each Option granted under the Plan shall be evidenced by
a written stock option executed by the Company and delivered to the
Participant, which shall be substantially in the form attached as Exhibit A
hereto, or shall be in such other form as specified by the Board. Such stock
option shall indicate whether such Option is to be an Incentive Stock Option
or a Nonqualified Stock Option and, if an Incentive Stock Option, shall
contain terms and conditions permitting such Option to qualify for treatment
as an incentive stock option under Section 422 of the Code.
 
  Section 9. Issuance of Common Stock. The Company's obligation to issue
shares of Common Stock upon the exercise of an Option is expressly conditioned
upon the making of such investment representations and related undertakings by
the Participant (or his legal representative, heir or legatee, as the case may
be) in order to comply with the requirements of any exemption from any
securities law registration or other qualification of such shares which the
Company in its sole discretion shall deem necessary or advisable. Such
required representations and undertakings may include representations and
agreements that such Participant (or his legal
 
                                      C-2
<PAGE>
 
representative, heir or legatee): (a) is purchasing such shares for investment
and not with any present intention of selling or otherwise disposing thereof;
and (b) agrees to have placed upon the face and reverse of any certificates
evidencing such shares a legend setting forth (i) any representations and
undertakings which such Participant has given to the Company or a reference
thereto, and (ii) that, prior to effecting any sale or other disposition of
any such shares, the Participant must furnish to the Company an opinion of
counsel, satisfactory to the Company and its counsel, to the effect that such
sale or disposition will not violate the applicable requirements of state and
federal laws and regulatory agencies.
 
  Section 10. Nontransferability. No Option shall be assignable or
transferable except by will or by the laws of descent and distribution. During
the lifetime of a Participant, any Option granted to him shall be exercisable
only by him. After the death of a Participant, the Option granted to him may
be exercised, prior to its termination as provided by Section 13(b), only by
his legal representative, his legatee or by any other person who acquired the
right to exercise the Option by reason of the death of the Participant.
 
  Section 11. Recapitalization, Reorganization, Merger or Consolidation. If
the outstanding shares of Common Stock of the Company are increased, decreased
or exchanged for different securities through reorganization, merger,
consolidation, recapitalization, reclassification, stock split, stock dividend
or like capital adjustment, a proportionate adjustment shall be made (a) in
the aggregate number of shares of Common Stock which may be issued pursuant to
the exercise of Options under the Plan, as provided in Section 5, and (b) in
the number, price and kind of shares subject to any outstanding Option granted
under the Plan.
 
  Upon the dissolution or liquidation of the Company or upon any
reorganization, merger or consolidation in which the Company does not survive,
the Plan and each outstanding Option shall terminate; provided that in such
event: (a) each Participant to whom no Option has been tendered by the
surviving corporation in accordance with all of the terms of clause (b)
immediately below shall have the right until five days before the effective
date of such dissolution or liquidation, or such merger or consolidation in
which the Company is not the surviving corporation, to exercise in whole or in
part any unexpired Option or Options issued to him, without regard to the
installment provisions of Section 7 of the Plan or any option agreement; or
(b) in its sole and absolute discretion, the surviving corporation may, but
shall not be so obligated, tender to any Participant holding an Option, an
option or options to purchase shares of the surviving corporation, and such
new option or options shall contain such terms and provisions as shall be
required to preserve substantially all of the rights and benefits of any
Option then outstanding under the Plan. Each Participant shall be given
written notice by the Company of any such proposed or contemplated
dissolution, liquidation, reorganization, merger or consolidation at least
thirty-five (35) days prior to the effective date thereof, which notice shall
advise such Participant of the proposed dissolution, liquidation,
reorganization, merger or consolidation and the rights of the Participant
pursuant to this paragraph.
 
  To the extent that the foregoing adjustments relate to stock or securities
of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. Except
as hereinbefore expressly provided in this Section 11, the Participant shall
have no rights by reason of any subdivision or consolidation of shares of
stock of any class or the payment of any stock dividend or any other increase
or decrease in the number of shares of stock of any class, and the number or
price of shares of Common Stock subject to any Option shall not be affected
by, and no adjustment shall be made by reason of, any dissolution,
liquidation, reorganization, merger or consolidation, or any issue by the
Company of shares of stock of any class, or rights to purchase or subscribe
for stock of any class, or securities convertible into shares of stock of any
class.
 
  The grant of an Option pursuant to the Plan shall not affect in any way the
right or power of the Company to make adjustments, reclassifications or
changes in its capital or business structures or to merge, consolidate,
dissolve or liquidate or to sell or transfer all or any part of its business
or assets.
 
  Section 12. Rights as a Shareholder. A Participant holding an Option, or a
transferee of an Option, shall have no rights as a shareholder with respect to
any shares covered by his Option until the date of the issuance of
 
                                      C-3
<PAGE>
 
a stock certificate to him for such shares, and no adjustment shall be made
for dividends (ordinary or extraordinary, whether in cash, securities or other
property) or distributions or other rights for which the record date is prior
to the date such stock certificate is issued, except as expressly provided in
Section 11.
 
  Section 13. Termination of Options. Each Option granted under the Plan shall
set forth a termination date thereof, which date shall be not later than ten
years from the date such Option is granted. Except where earlier termination
is required by the terms of the Option, all Options shall terminate and expire
upon the first to occur of the following events:
 
    (a) the expiration of 30 days from the date of such Participant's
  termination of employment (other than by reason of death), except that if
  the Participant is disabled (within the meaning of Section 22(e)(3) of the
  Internal Revenue Code) at the time of his termination of employment, the
  expiration of one year from the date of the Participant's termination of
  employment;
 
    (b) the expiration of 180 days from the date of the death of such
  Participant if his death occurs while he is employed by the Company or any
  of its subsidiaries; or
 
    (c) the termination of the Option pursuant to Section 11 of the Plan.
 
  The termination of employment of a Participant by death or otherwise shall
not accelerate or otherwise affect the number of shares with respect to which
an Option may be exercised, and the Option may only be exercised with respect
to that number of shares which could have been purchased under the Option had
the Option been exercised by the Participant on the date of such termination.
 
  For purposes of the above, in the case of Options granted to Participants
who are directors of the Company or consultants or advisors to the Company,
"employment" shall mean service as such director, consultant or advisor to the
Company.
 
  Section 14. Withholding of Taxes. The Company shall deduct and withhold from
the wages, salary, bonus and other income paid by the Company to the
Participant the requisite tax upon the amount of taxable income, if any,
recognized by the Participant in connection with the exercise in whole or in
part of any Option or the sale of Common Stock issued to the Participant upon
exercise of the Option, all as may be required from time to time under any
federal or state tax laws and regulations. This withholding of tax shall be
made from the Company's concurrent or next payment of wages, salary, bonus or
other income to the Participant or by payment to the Company by the
Participant of the required withholding tax, as the Board may determine.
 
  Section 15. Termination of Plan. The Plan shall terminate when all Options
granted hereunder either have been fully exercised, and all shares of Common
Stock which may be purchased pursuant to the exercise of such Options have
been so purchased, or have expired, and in any event not later than ten (10)
years from the date of the adoption of the plan or the date of the approval of
the Plan by the shareholders of the Company, whichever is earlier. However,
the Board may in its absolute discretion terminate the Plan at any time. No
such termination, other than as provided for in Section 11 hereof, shall in
any way affect any Option then outstanding.
 
  Section 16. Amendment of Plan. The Board may at any time amend or terminate
this Plan. However, no amendment or termination may impair the rights of the
Participant holding an Option without the Participant's consent. Also, except
as may otherwise be permitted under Rule 16b-3 promulgated by the Securities
and Exchange Commission, no amendment to the Plan may be adopted without the
approval of the shareholders that would materially (a) increase the number of
shares that may be issued to Participants subject to Section 16 of the
Securities Exchange Act of 1934 ("Insiders"), (b) increase the benefits
accruing to Insiders, or (c) modify the requirements for Insiders to
participate.
 
  Further, the approval of shareholders must also be obtained if the Plan is
amended in a way that relates to the class of individuals entitled to receive
Incentive Stock Options, or the aggregate number of shares of Common Stock
that may be issued under the Plan.
 
                                      C-4
<PAGE>
 
  Section 17. Amendment of Options. The Board may modify an existing Option,
including the right to (a) change the exercise price, (b) accelerate the right
to exercise it, (c) extend or renew it, or (d) cancel it and issue a new
Option. However, no modification may be made to an Option that would impair
the rights of the Participant holding the Option without his consent. Whether
a modification of an existing Incentive Stock Option will be treated as the
issuance of a new Incentive Stock Option will be determined in accordance with
the rules of Code Section 424(h). Whether a modification of an existing Option
granted to an Insider will be treated as a new grant for purposes of Section
16 of the Securities Exchange Act of 1934 will be determined in accordance
with Rule 16b-3.

                    AMENDMENT TO THE 1991 STOCK OPTION PLAN
 
  The first sentence of Section 5 ("Shares Subject to the Plan") of the 1991
Stock Option Plan of Plasma & Materials Technologies, Inc. ("PMT") is hereby
amended to read as follows: "The number of shares of Common Stock which may be
purchased pursuant to the exercise of Options granted under the Plan shall be
1,300,000 shares; provided, however, that such number shall be increased to
2,400,000 shares upon, and subject to the occurrence of, the closing
contemplated by that certain Share Purchase Agreement dated as of July 17,
1996 among PMT, Electrotech Limited and Electrotech Equipments Limited
(collectively, "Electrotech") and the shareholders of Electrotech pursuant to
which PMT acquires all of the outstanding capital stock of Electrotech."

                     GENERAL CORPORATION LAW OF CALIFORNIA
 
                                  CHAPTER 13
 
                              DISSENTERS' RIGHTS
 
(S) 1300. RIGHT TO REQUIRE PURCHASE--"DISSENTING SHARES" AND "DISSENTING
SHAREHOLDER" DEFINED.
 
  (a) If the approval of the outstanding shares (Section 152) of a corporation
is required for a reorganization under subdivisions (a) and (b) or subdivision
(e) or (f) of Section 1201, each shareholder of the corporation entitled to
vote on the transaction and each shareholder of a subsidiary corporation in a
short-form merger may, by complying with this chapter, require the corporation
in which the shareholder holds shares to purchase for cash at their fair
market value the shares owned by the shareholder which are dissenting shares
as defined in subdivision (b). The fair market value shall be determined as of
the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or
depreciation in consequence of the proposed action, but adjusted for any stock
split, reverse stock split, or share dividend which becomes effective
thereafter.
 
  (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:
 
    (1) Which were not immediately prior to the reorganization or short-form
  merger either (A) listed on any national securities exchange certified by
  the Commissioner of Corporations under subdivision (o) of Section 25100 or
  (B) listed on the list of OTC margin stocks issued by the Board of
  Governors of the Federal Reserve System, and the notice of meeting of
  shareholders to act upon the reorganization summarizes this section and
  Sections 1301, 1302, 1303 and 1304; provided, however, that this provision
  does not apply to any shares with respect to which there exists any
  restriction on transfer imposed by the corporation or by any law or
  regulation; and provided, further, that this provision does not apply to
  any class of shares described in subparagraph (A) or (B) if demands for
  payment are filed with respect to 5 percent or more of the outstanding
  shares of that class.
 
    (2) Which were outstanding on the date for the determination of
  shareholders entitled to vote on the reorganization and (A) were not voted
  in favor of the reorganization or, (B) if described in subparagraph (A) or
  (B) of paragraph (1) (without regard to the provisos in that paragraph),
  were voted against the reorganization, or which were held of record on the
  effective date of a short-form merger; provided, however, that subparagraph
  (A) rather than subparagraph (B) of this paragraph applies in any case
  where the approval required by Section 1201 is sought by written consent
  rather than at a meeting.
 
    (3) Which the dissenting shareholder has demanded that the corporation
  purchase at their fair market value, in accordance with Section 1301.
 
    (4) Which the dissenting shareholder has submitted for endorsement, in
  accordance with Section 1302.
 
  (c) As used in this chapter, "dissenting shareholder" means the recordholder
of dissenting shares and includes a transferee of record.
 
(S) 1301. DEMAND FOR PURCHASE.
 
  (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the
 
                                      E-1
<PAGE>
 
procedure to be followed if the shareholder desires to exercise the
shareholder's right under such sections. The statement of price constitutes an
offer by the corporation to purchase at the price stated any dissenting shares
as defined in subdivision (b) of Section 1300, unless they lose their status
as dissenting shares under Section 1309.
 
  (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance
with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
  (c) The demand shall state the number and class of the shares held of record
by the shareholder which the shareholder demands that the corporation purchase
and shall contain a statement of what such shareholder claims to be the fair
market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market
value constitutes an offer by the shareholder to sell the shares at such
price.
 
(S) 1302. ENDORSEMENT OF SHARES.
 
  Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110
was mailed to the shareholder, the shareholder shall submit to the corporation
at its principal office or at the office of any transfer agent thereof, (a) if
the shares are certificated securities, the shareholder's certificates
representing any shares which the shareholder demands that the corporation
purchase, to be stamped or endorsed with a statement that the shares are
dissenting shares or to be exchanged for certificates of appropriate
denomination so stamped or endorsed or (b) if the shares are uncertificated
securities, written notice of the number of shares which the shareholder
demands that the corporation purchase. Upon subsequent transfers of the
dissenting shares on the books of the corporation, the new certificates,
initial transaction statement, and other written statements issued therefor
shall bear a like statement, together with the name of the original dissenting
holder of the shares.
 
(S) 1303. AGREED PRICE--TIME FOR PAYMENT.
 
  (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the
fair market value of any dissenting shares as between the corporation and the
holders thereof shall be filed with the secretary of the corporation.
 
  (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount
thereof has been agreed or within 30 days after any statutory or contractual
conditions to the reorganization are satisfied, whichever is later, and in the
case of certificated securities, subject to surrender of the certificates
therefor, unless provided otherwise by agreement.
 
(S) 1304. DISSENTER'S ACTION TO ENFORCE PAYMENT.
 
  (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of
the shares, then the shareholder demanding purchase of such shares as
dissenting shares or any interested corporation, within six months after the
date on which notice of the approval by the outstanding shares (Section 152)
or notice pursuant to subdivision (i) of Section 1110 was mailed to the
shareholder, but not thereafter, may file a complaint in the superior court of
the proper county praying the court to determine whether the shares are
dissenting shares or the fair market value of the dissenting shares or both or
may intervene in any action pending on such a complaint.
 
                                      E-2
<PAGE>
 
  (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
  (c) On the trial of the action, the court shall determine the issues. If the
status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.
 
(S) 1305. APPRAISERS' REPORT--PAYMENT COSTS.
 
  (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed
by the court, the appraisers, or a majority of them, shall make and file a
report in the office of the clerk of the court. Thereupon, on the motion of
any party, the report shall be submitted to the court and considered on such
evidence as the court considers relevant. If the court finds the report
reasonable, the court may confirm it.
 
  (b) If a majority of the appraisers appointed fail to make and file a report
within 10 days from the date of their appointment or within such further time
as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.
 
  (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market
value of each dissenting share multiplied by the number of dissenting shares
which any dissenting shareholder who is a party, or who has intervened, is
entitled to require the corporation to purchase, with interest thereon at the
legal rate from the date on which judgment was entered.
 
  (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for
the shares described in the judgment. Any party may appeal from the judgment.
 
  (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than
125 percent of the price offered by the corporation under subdivision (a) of
Section 1301).
 
(S) 1306. DISSENTING SHAREHOLDER'S STATUS AS CREDITOR.
 
  To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.
 
(S) 1307. DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.
 
  Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.
 
(S) 1308. CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.
 
  Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined.
A dissenting shareholder may not withdraw a demand for payment unless the
corporation consents thereto.
 
                                      E-3
<PAGE>
 
(S) 1309. TERMINATION OF DISSENTING SHAREHOLDER STATUS.
 
  Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to
require the corporation to purchase their shares upon the happening of any of
the following:
 
    (a) The corporation abandons the reorganization. Upon abandonment of the
  reorganization, the corporation shall pay on demand to any dissenting
  shareholder who has initiated proceedings in good faith under this chapter
  all necessary expenses incurred in such proceedings and reasonable
  attorneys' fees.
 
    (b) The shares are transferred prior to their submission for endorsement
  in accordance with Section 1302 or are surrendered for conversion into
  shares of another class in accordance with the articles.
 
    (c) The dissenting shareholder and the corporation do not agree upon the
  status of the shares as dissenting shares or upon the purchase price of the
  shares, and neither files a complaint or intervenes in a pending action as
  provided in Section 1304, within six months after the date on which notice
  of the approval by the outstanding shares or notice pursuant to subdivision
  (i) of Section 1110 was mailed to the shareholder.
 
    (d) The dissenting shareholder, with the consent of the corporation,
  withdraws the shareholder's demand for purchase of the dissenting shares.
 
(S) 1310. SUSPENSION OF PROCEEDINGS FOR PAYMENT PENDING LITIGATION.
 
  If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings
under Sections 1304 and 1305 shall be suspended until final determination of
such litigation.
 
(S) 1311. EXEMPT SHARES.
 
  This chapter, except Section 1312, does not apply to classes of shares whose
terms and provisions specifically set forth the amount to be paid in respect
to such shares in the event of a reorganization or merger.
 
(S) 1312. ATTACKING VALIDITY OF REORGANIZATION OR MERGER.
 
  (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set
aside or rescinded, except in an action to test whether the number of shares
required to authorize or approve the reorganization have been legally voted in
favor thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event
of a reorganization or short-form merger is entitled to payment in accordance
with those terms and provisions or, if the principal terms of the
reorganization are approved pursuant to subdivision (b) of Section 1202, is
entitled to payment in accordance with the terms and provisions of the
approved reorganization.
 
  (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash
for such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-
form merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand
payment of cash for the shareholder's shares pursuant to this chapter. The
court in any action attacking the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded shall not restrain or enjoin the consummation of the
 
                                      E-4
<PAGE>
 
transaction except upon 10 days' prior notice to the corporation and upon a
determination by the court that clearly no other remedy will adequately
