                      AGREEMENT AND PLAN OF REORGANIZATION
 
    AGREEMENT AND PLAN OF REORGANIZATION (this "AGREEMENT"), dated as of June 1,
1998, is made by and among Advanced Energy Industries, Inc., a Delaware
corporation ("PARENT"), Warpspeed, Inc., a New Jersey corporation and a wholly
owned subsidiary of Parent ("MERGER SUB"), and RF Power Products, Inc., a New
Jersey corporation (the "COMPANY").
 
                                R E C I T A L S
 
    A. The Boards of Directors of Parent and the Company each have determined
that a business combination between Parent and the Company would enable the
companies to achieve long-term strategic and financial benefits and,
accordingly, is in the best interests of their respective stockholders. Each of
such Boards of Directors desires to effect the Merger (as defined herein), on
the terms and subject to the conditions set forth herein.
 
    B.  It is intended that the Merger qualify as a reorganization within the
meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the
"CODE"), for federal income tax purposes.
 
    C.  It is intended that the Merger be accounted for as a pooling of
interests for financial accounting purposes.
 
    D. Parent has incorporated and organized Merger Sub solely to facilitate the
Merger.
 
    NOW, THEREFORE, in consideration of the mutual covenants and subject to the
terms and conditions set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:
 
                                   ARTICLE 1
                                   THE MERGER
 
    1.1.  THE BASIC TRANSACTION.  On the terms and subject to the conditions of
this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub
shall be merged with and into the Company in accordance with this Agreement, and
the separate corporate existence of Merger Sub shall thereupon cease (the
"MERGER"). The Company shall be the surviving corporation in the Merger
(sometimes hereinafter referred to as the "SURVIVING CORPORATION"), and shall
become a wholly owned subsidiary of Parent. The Merger shall have the effects
specified in the New Jersey Business Corporation Act (the "NJBCA").
 
    1.2.  THE CLOSING.  Subject to the terms and conditions of this Agreement,
the closing of the Merger (the "CLOSING") shall take place (a) at the offices of
Thelen, Reid & Priest LLP, New York, New York at 10:00 a.m., local time, on the
first business day immediately following the day on which the last to be
fulfilled or waived of the conditions set forth in Article 6 shall be completely
fulfilled or waived in accordance herewith, or (b) at such other time, date or
place as Parent and the Company may agree. The date on which the Closing occurs
is hereinafter referred to as the "CLOSING DATE."
 
    1.3.  EFFECTIVE TIME.  On the Closing Date, a Certificate of Merger meeting
the requirements of Section 14A:10-4.1 of the NJBCA shall be executed and filed
in the office of the New Jersey Secretary of State, in accordance with the
NJBCA. The Merger shall become effective at (a) the time of filing of the
Certificate of Merger with the New Jersey Secretary of State or (b) such later
time as agreed by the parties hereto and designated in the Certificate of Merger
as the effective time of the Merger (the "EFFECTIVE TIME").
 
    1.4.  CERTIFICATE OF INCORPORATION AND BY-LAWS.  The Certificate of
Incorporation and By-laws of Merger Sub in effect immediately prior to the
Effective Time shall be the Certificate of Incorporation and By-laws of the
Surviving Corporation, until duly amended in accordance with applicable law.
 


    1.5.  DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION.  The directors
and officers of Merger Sub immediately prior to the Effective Time shall be the
directors and officers of the Surviving Corporation until their successors are
duly appointed or elected in accordance with applicable law; and Joseph Stach,
president and chief executive officer of the Company, also shall become an
officer of the Surviving Corporation.
 
                                   ARTICLE 2
                     CONVERSION AND EXCHANGE OF SECURITIES
 
    2.1.  MERGER SUB STOCK.  At the Effective Time, each share of common stock,
par value $0.01 per share, of Merger Sub outstanding immediately prior to the
Effective Time shall be converted into and exchanged for one validly issued,
fully paid and non-assessable share of common stock, par value $0.01 per share,
of the Surviving Corporation.
 
    2.2.  COMPANY STOCK; OPTIONS.
 
        (a)  EXCHANGE RATIO.  At the Effective Time, each share of common stock,
    par value $0.01 per share, of the Company ("COMPANY COMMON STOCK") that is
    issued and outstanding immediately prior to the Effective Time shall, by
    virtue of the Merger and without any action on the part of the holder
    thereof, be converted into the right to receive the number of shares of
    common stock, par value $0.001 per share, of Parent (the "PARENT COMMON
    STOCK") that is equal to 3,750,000 divided by the number of shares of
    Company Common Stock issued and outstanding immediately prior to the
    Effective Time (the "EXCHANGE RATIO"); provided, however, that (A) if the
    Closing Price (as defined in this Section 2.2) is less than or equal to
    $12.11, then the Exchange Ratio shall be the result obtained by dividing
    $3.74 by the Closing Price, but in no event shall the Exchange Ratio
    computed pursuant to this clause (A) be greater than 4,000,000 divided by
    the number of shares of Company Common Stock issued and outstanding
    immediately prior to the Effective Time (the "EFFECTIVE TIME SHARE NUMBER")
    and (B) if the Closing Price is greater than or equal to $16.39, the
    Exchange Ratio shall be the result obtained by dividing, $5.06 by the
    Closing Price, but in no event shall the Exchange Ratio computed pursuant to
    this clause (B) be less than 3,500,000 divided by the Effective Time Share
    Number. "CLOSING PRICE" means the average closing price of the Parent Common
    Stock, as reported in The Wall Street Journal, Eastern Edition, for each of
    the 10 consecutive Trading Days immediately preceding the third Trading Day
    prior to the Stockholders Meeting (as defined in Section 5.4). "TRADING DAY"
    means a day on which trading is conducted on the Nasdaq National Market.
 
        (b)  CANCELLATION OF COMPANY COMMON STOCK.  At the Effective Time, as a
    result of the Merger and without any action on the part of the holders
    thereof, all shares of Company Common Stock shall cease to be outstanding,
    shall be canceled and retired and shall cease to exist, and each holder of
    shares of Company Common Stock shall thereafter cease to have any rights
    with respect to such shares of Company Common Stock, except the right to
    receive upon the surrender of a certificate (a "CERTIFICATE") representing
    such shares of Company Common Stock (i) the number of shares of Parent
    Common Stock determined in accordance with this Section 2.2, and (ii) cash,
    without interest, payable (A) in lieu of any fractional shares of Parent
    Common Stock, in accordance with Section 2.3(b), and (B) as Specified
    Post-Closing Dividends (as defined in Section 2.3), in accordance with
    Section 2.3(f).
 
        (c)  TREASURY SHARES AND SHARES HELD BY SUBSIDIARIES.  At the Effective
    Time, as a result of the Merger and without any action on the part of
    Parent, Merger Sub or the Company, any and all shares of Company Common
    Stock issued and held in the Company's treasury or held by a Subsidiary of
    the Company shall cease to be outstanding, shall be canceled and retired
    without payment of any consideration therefor and shall cease to exist.
 
        (d)  OPTIONS.
 
            (i) At the Effective Time, as a result of the Merger and without any
       action on the part of holder thereof, each option to purchase Company
       Common Stock granted by the Company
 


       (collectively, "COMPANY OPTIONS") under one of its stock option plans
       (collectively, "COMPANY OPTION PLANS") that remains outstanding and
       unexercised as of the Effective Time, whether or not vested or
       exercisable, shall be assumed by Parent and shall be converted into an
       option to purchase Parent Common Stock (collectively, "SUBSTITUTED
       OPTIONS").
 
            (ii) Subject to subsection 2.2(d)(iii) below, (A) the number of
       shares of Parent Common Stock underlying a Substituted Option shall be
       equal to the number of shares of Company Common Stock underlying the
       subject Company Option multiplied by the Exchange Ratio and rounded to
       the nearest whole number, (B) the exercise price per share of a
       Substituted Option shall be equal to the exercise price of the subject
       Company Option divided by the Exchange Ratio and rounded to the nearest
       cent, and (C) each Substituted Option shall be exercisable on the same
       terms and subject to the same conditions as had been applicable to the
       related Company Option, except to the extent the number of shares and
       exercise price per share have been adjusted pursuant to (A) and (B),
       respectively, of this subsection 2.2(d)(ii).
 
           (iii) It is the intention of the parties that Company Options that
       qualified as incentive stock options, within the meaning of Section 422
       of the Code ("ISOS"), immediately prior to the Effective Time, be
       converted, when assumed by Parent, into Substituted Options that qualify
       as ISOs immediately following the Effective Time, to the extent permitted
       by Section 422 of the Code and applicable terms of the Company Option
       Plans. In furtherance of such intention, the formulae, terms and
       conditions set forth in subsection 2.2(d)(ii) above may be applied to, or
       modified for, such Substituted Options as deemed reasonably necessary by
       Parent, so long as any such application or modification does not reduce
       the benefit of the Substituted Option to the holder thereof.
 
            (iv) On or prior to the Effective Time, Parent shall file with the
       Securities and Exchange Commission (the "COMMISSION") a Registration
       Statement on Form S-3 or Form S-8, as determined by Parent in its sole
       discretion, relating to the issuance of the Parent Common Stock
       underlying the Substituted Options or shall cause such Parent Common
       Stock to be included in an effective Registration Statement on Form S-8
       relating to one or more of Parent's stock option plans (collectively,
       "PARENT OPTION PLANS"). So long as any Substituted Options remain
       outstanding, Parent shall use its best efforts to maintain the
       effectiveness of any Registration Statement or Statements relating to the
       Substituted Options (and to maintain the current status of the prospectus
       or prospectuses related thereto). At or prior to the Effective Time,
       Parent shall take all corporate action necessary to reserve for issuance
       a sufficient number of shares of Parent Common Stock for delivery upon
       exercise of the Substituted Options.
 
    2.3.  EXCHANGE OF CERTIFICATES REPRESENTING COMPANY COMMON STOCK.
 
        (a) As of the Effective Time, Parent shall deposit, or shall cause to be
    deposited, with an exchange agent reasonably acceptable to the Company (the
    "EXCHANGE AGENT"), for the benefit of the holders of Company Common Stock,
    for exchange in accordance with this Article 2, (i) certificates
    representing the shares of Parent Common Stock to be issued in connection
    with the Merger ("MERGER CERTIFICATES"), and (ii) Parent's good faith
    estimate of the cash in lieu of fractional shares expected to be payable in
    connection with the Merger. Such cash and Merger Certificates are referred
    to herein as the "EXCHANGE FUND."
 
        (b) No fractional shares of Parent Common Stock shall be issued pursuant
    hereto. In lieu of the issuance of any fractional share of Parent Common
    Stock, cash will be paid in respect of any fractional share of Parent Common
    Stock that would otherwise be issuable, and the amount of such cash shall be
    equal to such fractional proportion of the Closing Price. No interest will
    be paid or accrued on the cash payable to holders of shares of Company
    Common Stock.
 
        (c) Promptly after the Effective Time, Parent shall cause the Exchange
    Agent to mail to each holder of record of Company Common Stock (i) a letter
    of transmittal, in a form and having such
 


    provisions as Parent may reasonably specify ("LETTER OF TRANSMITTAL"), which
    shall advise the holder that delivery of Merger Certificates shall be
    effected, and risk of loss and title to such holder's shares of Company
    Common Stock shall pass, only upon delivery of the Certificates representing
    such shares to the Exchange Agent, and (ii) instructions for use in
    effecting the surrender of such Certificates in exchange for Merger
    Certificates and cash in lieu of fractional shares from the Exchange Fund.
 
        (d) Upon surrender of a Certificate to the Exchange Agent for
    cancellation, together with a duly executed and properly completed Letter of
    Transmittal, (i) the holder of the shares of Company Common Stock
    represented by such Certificate shall be entitled to receive in exchange
    therefor from the Exchange Fund (A) a Merger Certificate representing that
    number of whole shares of Parent Common Stock determined by multiplying the
    number of shares of Company Common Stock represented by the Certificate by
    the Exchange Ratio, and (B) a check representing (1) the amount of cash in
    lieu of fractional shares of Parent Common Stock, if any, determined
    pursuant to paragraph (b) of this Section 2.3, and (2) any Specified
    Post-Closing Dividends, in each case less any applicable tax withholding,
    and (ii) the Company Common Stock represented by the surrendered Certificate
    shall thereupon be canceled.
 
        (e) In the event of a transfer of ownership of Company Common Stock
    which is not registered in the transfer records of the Company, a Merger
    Certificate representing the proper number of shares of Parent Common Stock,
    together with a check for the cash to be paid in lieu of fractional shares,
    if any, may be issued to such transferee of such Company Common Stock, if
    the Certificate representing such Company Common Stock is presented to the
    Exchange Agent, accompanied by all documents, in form and substance
    reasonably satisfactory to Parent and the Exchange Agent, required to
    evidence and effect such transfer of Company Common Stock and to evidence
    that any applicable stock transfer taxes have been paid. There shall be no
    transfers on the transfer records of the Company, at or after the Effective
    Time, of shares of Company Common Stock which were outstanding immediately
    prior to the Effective Time.
 
        (f) Notwithstanding any other provisions of this Agreement, no dividends
    or other distributions declared after the Effective Time on Parent Common
    Stock ("POST-CLOSING DIVIDENDS") shall be paid with respect to any shares of
    Company Common Stock represented by a Certificate until such Certificate is
    surrendered for exchange as provided herein. Subject to the effect of
    applicable laws, following surrender of any such Certificate, there shall be
    paid to the holder of the certificates representing whole shares of Parent
    Common Stock issued in exchange therefor, without interest, (i) at the time
    of such surrender, the amount of Post-Closing Dividends with a record date
    after the Effective Time theretofore payable with respect to such whole
    shares of Parent Common Stock and not paid, less the amount of any
    withholding taxes which may be required thereon ("SPECIFIED POST-CLOSING
    DIVIDENDS"), and (ii) at the appropriate payment date, the amount of
    Post-Closing Dividends with a record date after the Effective Time but prior
    to surrender and a payment date subsequent to surrender payable with respect
    to such whole shares of Parent Common Stock, less the amount of any
    withholding taxes which may be required thereon.
 
        (g) Certificates surrendered for exchange by any person that is an
    "affiliate" of the Company for purposes of Rule 145(c) under the Securities
    Act of 1933, as amended (the "SECURITIES ACT"), shall not be exchanged until
    Parent has received a written agreement from such person as provided in
    Section 5.11.
 
        (h) One year after the Effective Time, the Exchange Agent shall deliver
    to the Surviving Corporation any portion of the Exchange Fund (including the
    proceeds of any investments thereof and any shares of Parent Common Stock)
    that remains unclaimed by the former stockholders of the Company.
    Thereafter, former stockholders of the Company that have not surrendered
    their Certificates for exchange shall look to the Surviving Corporation for
    delivery of Merger Certificates, cash in lieu of fractional shares and
    unpaid Post-Closing Dividends which such former stockholder is entitled
 


    to receive in respect of the Company Common Stock represented by the
    theretofore unsurrendered Certificates, in each case, without any interest
    thereon.
 
        (i) None of Parent, the Company, the Surviving Corporation, the Exchange
    Agent or any other person shall be liable to any former stockholder of the
    Company for any amount properly delivered to a public official pursuant to
    applicable abandoned property, escheat or similar laws.
 
    2.4.  LOST CERTIFICATES.  In the event any Certificate shall have been lost,
stolen or destroyed, upon the making and delivery of an affidavit of that fact
by the person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such Certificate,
the Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the shares of Parent Common Stock and cash deliverable in respect
thereof pursuant to this Agreement.
 
    2.5.  ADJUSTMENT OF EXCHANGE RATIO.  In the event that, subsequent to the
date of this Agreement but prior to the Effective Time, the outstanding shares
of Parent Common Stock shall have been changed into a different number of shares
or a different class as a result of a stock split, reverse stock split, stock
dividend, subdivision, reclassification, combination, exchange, recapitalization
or other similar transaction, the Exchange Ratio shall be appropriately
adjusted.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    Except as set forth in the disclosure schedule delivered at or prior to the

    stock of the Company or of the Company Subsidiary.
 
        (c) Neither the Company nor Company Subsidiary has any outstanding
    bonds, debentures, notes or other obligations pursuant to which the holders

    binding obligation of the Company, enforceable in accordance with its terms,
    subject to applicable bankruptcy, insolvency, moratorium or other similar

    termination or forfeiture under (i) any terms or provisions of the
    Certificate of Incorporation or the Bylaws of the Company, (ii) any statute,
    rule, regulation, judicial, governmental, regulatory or administrative
    decree, order or judgment applicable to the Company or Company Subsidiary,
    or (iii) any agreement, lease, license, permit or other instrument to which

        (e) There is no action, suit, proceeding or investigation pending or, to
    the knowledge of the Company, threatened against the Company that questions
    the validity of this Agreement or the right of the Company to enter into

have a Company Material Adverse Effect, the Company and Company Subsidiary (i)
have all valid and current permits, licenses, orders, authorizations,
registrations, approvals and other analogous instruments (collectively,
"PERMITS"), and each Permit is in full force and effect, and (ii) have made all
filings and registrations and the like, necessary or required by law to conduct
their respective businesses as currently conducted. Neither the Company nor
Company Subsidiary has received any governmental notice of any violation by such
company of any laws, rules, regulation or orders applicable to their respective
businesses. Except where the failure to comply would not have a Company Material
Adverse Effect, (a) neither the Company nor Company Subsidiary is in default or
is not in compliance under any Permits, and (b) the business and operations of
each of the Company and Company Subsidiary are in compliance with all applicable
foreign, federal, state, local and county laws, ordinances, regulations,

    3.6.  COMPANY REPORTS.
 
        (a) The Company has filed all reports, forms, registrations, schedules,
    statements and other documents required to be filed by it with the
    Commission since January 1, 1995 (the "COMPANY REPORTS"). As of their
    respective dates, the Company Reports complied as to form in all material
    respects with the requirements of the Securities Act or the Exchange Act, as
    the case may be, and the applicable rules and regulations promulgated
    thereunder. Except to the extent that information contained in any Company
    Report has been amended, revised or superseded by a Company Report
    subsequently filed and publicly available prior to the date of this
    Agreement, none of the Company Reports, when filed, contained any untrue
    statement of a material fact or omitted 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.
 
        (b) Each of the consolidated balance sheets of the Company included in
    or incorporated by reference into the Company Reports (including the related
    notes and schedules) fairly presents in all material respects the
    consolidated financial position of the Company and Company Subsidiary as of
    its date, and each of the consolidated statements of income, retained
    earnings and cash flows of the Company included in or incorporated by
    reference into the Company Reports (including any related notes and
    schedules) fairly presents in all material respects the results of
    operations and cash flows of the Company and Company Subsidiary for the
    periods set forth therein (subject, in the case of unaudited statements, to
    normal year-end audit adjustments which would not be material in amount or
    effect), in each case in accordance with U.S. generally accepted accounting
    principles consistently applied during the periods involved ("GAAP"), except
    as may be noted therein and subject to the fact that unaudited financial
    statements do not contain full notes thereto. Neither the Company nor
    Company Subsidiary has any liabilities or obligations required to be
    disclosed in a consolidated balance sheet or the notes thereto prepared in
    accordance with GAAP, except (i) liabilities or obligations reflected on, or
    reserved against in, a consolidated balance sheet of the Company or in the
    notes thereto, and included in the Company Reports, (ii) liabilities or
    obligations incurred since February 28, 1998, in the ordinary course of

    any kind, or before or by any federal, state, municipal or other

    reasonably likely to have a Company Material Adverse Effect.
 
        (b) There are no outstanding orders, writs, injunctions, decrees,

    of or otherwise relate to the Company, Company Subsidiary or either of their
    businesses or properties, of any court or arbitrator or under any
    outstanding order, regulation or demand of any federal, state, municipal or
    other governmental instrumentality, domestic or foreign, that are reasonably
    likely to have a Company Material Adverse Effect.

which is filed as an exhibit to or described in a Company Report and (b)
material agreement, contract and commitment entered into by the Company, or by
which it became bound, after the date of the Quarterly Report on Form 10-Q most
recently filed by the Company (collectively, "COMPANY CONTRACTS"), is a valid
and legally binding obligation of the Company and, to the knowledge of the
Company, the other parties thereto, enforceable against the Company and, to the
knowledge of the Company, the other parties thereto, in accordance with its
terms, subject to the Enforceability Exceptions. The Company is not, and to the
knowledge of the Company no other party to any Company Contract is, in material
default thereof. The Company has not, and to the knowledge of the Company no
other party to any Company Contract has, performed any act or omitted to perform
any act which act or omission, with the giving of notice or passage of time or
otherwise, will become a material default thereunder.
 
    3.11  INTELLECTUAL PROPERTY.

       and obtain renewals and extensions

            (vi) all other intangible assets, properties and rights (whether or
       not appropriate steps have been taken to protect, under applicable law,
       such other intangible assets, properties or rights).
 
        (b) The Company owns or has the right to use all Intellectual Property
    used in the operation of its business as presently conducted, without any
    interference or conflict with or misappropriation or infringement of the
    Intellectual Property rights of others, other than any interference,
    conflict, misappropriation or infringement which is not reasonably likely to
    result in (i) a material adverse effect on the Company's ability to
    manufacture or sell any of its material products or any material line of
    products or otherwise to operate its business, (ii) a material liability of
    the Company, or (iii) material redesign or other corrective costs to the
    Company. The Company has taken reasonably necessary action to maintain and
    protect its rights in the material Intellectual Property that it owns or
    uses. Each material item of Intellectual Property owned or used by the
    Company immediately prior to the Effective Time hereunder will be owned or
    available for use by the Surviving Corporation on substantially identical
    terms and conditions immediately subsequent to the Effective Time.
 
        (c) Section 3.11 of the Company Disclosure Schedule sets forth all

        (d) The Company has not, within the past four years, interfered with,
    infringed upon, misappropriated, or otherwise come into conflict with any
    Intellectual Property rights of others other than any interference,

    material liability of the Company, or (iii) material redesign or other
    corrective costs to the Company. The Company has not received, and has no
    knowledge of, any charge, complaint, claim, demand or notice alleging any
    such interference, infringement, misappropriation, or conflict (including,
    without limitation, any claim that the Company must license or refrain from
    using any Intellectual Property rights of any other person), or that the
    Company's use of the Intellectual Property constitutes unfair competition.
 
        (e) To the knowledge of the Company, no fraud or misrepresentation has
    been made by the Company or any of its officers, directors or employees or
    the relevant inventors during the prosecution of any of the Patents of the
    Company, nor has any fraud or misrepresentation been included in any
    documentation for or other disclosure of the Intellectual Property of the
    Company.
 
    3.12.  EMPLOYEE BENEFIT PLANS.
 
        (a) For purpose of this Agreement, (i) "COMPANY BENEFIT PLANS" means all
    employee benefit plans and other benefit arrangements covering employees or
    former employees of the Company and all employee agreements providing
    compensation, severance or other benefits to any employee or former employee
    of the Company; and (ii) "ERISA AFFILIATE" means any business or entity
    which is a
 


    member of the same "controlled group of corporations," under "common
    control" or an "affiliated service group" with an entity within the meanings
    of Sections 414(b), (c) or (m) of the Code, or required to be aggregated
    with the entity under Section 414(o) of the Code, or is under "common
    control" with the entity, within the meaning of Section 4001(a)(14) of the
    Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
    any regulations promulgated or proposed under any of the foregoing Sections.
 
        (b) With respect to each Company Benefit Plan that is intended to be a
    "qualified plan" within the meaning of Section 401(a) of the Code, either
    (i) the Internal Revenue Service (the "IRS") has issued a favorable
    determination letter that has not been revoked, or (ii) an application for a
    favorable determination letter was timely submitted to the IRS for which no
    final action has been taken by the IRS. To the knowledge of the Company,
    there is no reason that is not susceptible to cure why the qualified status
    under Section 401(a) of the Code of any Company Benefit Plan would be denied
    or revoked, whether retroactively or prospectively.
 
        (c) Except as would not have a Company Material Adverse Effect, no
    Company Benefit Plan, any fiduciary thereof, nor the Company has incurred
    any liability or penalty under Section 4975 of the Code or Section 502(i) of
    ERISA. Except as would not have a Company Material Adverse Effect, each
    Company Benefit Plan has been maintained and administered in all material
    respects in compliance with its terms and with ERISA and the Code, to the
    extent applicable thereto.
 
        (d) Except as would not have a Company Material Adverse Effect, neither
    the Company nor any ERISA Affiliate (during the period of its affiliated
    status) has any existing liability currently due and payable that has not
    been satisfied in full under Title IV of ERISA or Section 412 of the Code.
    To the knowledge of the Company, there are no current plans to terminate,
    whether voluntarily or involuntarily, any materially underfunded pension
    plan of the Company or any ERISA Affiliate that is subject to Title IV of
    ERISA.
 
        (e) Except as would not have a Company Material Adverse Effect, to the
    knowledge of the Company, there are no pending or anticipated claims against
    or otherwise involving any of the Company Benefit Plans and no suit, action
    or other litigation (excluding claims for benefits incurred in the ordinary
    course of the Company Benefit Plan activities) has been brought against or
    with respect to any such Company Benefit Plan, except for any of the
    foregoing which would not have a Company Material Adverse Effect.
 
        (f) All material contributions required to be made as of the date hereof
    to the Company Benefit Plans have been made or provided for.
 
        (g) The execution of, and performance of the transactions contemplated
    by, this Agreement will not (either alone or upon the occurrence of any
    additional or subsequent events) constitute an event under any benefit plan,
    policy, arrangement or agreement or any trust or loan that will or is
    reasonably likely to result in any payment (whether of severance pay or
    otherwise), acceleration, forgiveness of indebtedness, vesting,
    distribution, increase in benefits or obligation to fund benefits with
    respect to any employee of the Company.
 
        (h) The Company has not entered into any severance agreements or adopted
    any severance policies applicable to the Company or its employees.
 
    3.13.  NO BROKERS.  The Company has not entered into any contract,
arrangement or understanding with any person or firm which will or is reasonably
likely to result in the obligation of the Company, Parent or Merger Sub to pay
any finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or the consummation
of the transactions contemplated hereby, except that the Company has retained
NationsBanc Montgomery Securities LLC as its financial advisor, the arrangements
with which have been disclosed in writing to Parent prior to the date hereof.
Other than the foregoing arrangements, the Company is not aware of any claim for
payment of any
 


finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or the consummation
of the transactions contemplated hereby.
 
    3.14.  OPINION OF FINANCIAL ADVISOR.  The Company has received the opinion
of NationsBanc Montgomery Securities LLC substantially to the effect that, as of
the date hereof, the Exchange Ratio is fair to the holders of Company Common
Stock from a financial point of view.
 
    3.15.  PARENT STOCK OWNERSHIP.  Neither the Company nor any of its
Subsidiaries owns any shares of Parent Common Stock or other securities
convertible into Parent Common Stock.
 
    3.16.  POOLING OF INTERESTS; TAX REORGANIZATION.  To the knowledge of the
Company, having sought and obtained the advice of its accounting advisors, the
Company has not taken (or as of the date hereof failed to take) any action which
would prevent the accounting for the Merger as a pooling of interests in
accordance with Accounting Principles Board Opinion No. 16 ("APB NO. 16"), the
interpretative releases issued pursuant thereto, and the pronouncements of the
Commission. To the knowledge of the Company, the Company has not taken or failed
to take any action which would prevent the Merger from constituting a
reorganization within the meaning of section 368 of the Code.
 
    3.17.  ENVIRONMENTAL MATTERS.
 
        (a) For purposes of this Agreement, (i) "ENVIRONMENTAL REQUIREMENTS"
    means any applicable laws, regulations, ordinances or other provisions
    having the force or effect of law, or any judicial, governmental, or
    administrative orders, requests, or determinations, or any common law
    requirements relating to the protection of human health or the environment
    (both natural and workplace), including without limitation any Environmental
    Requirements concerning (A) the use, generation, treatment, storage,
    transportation, handling or disposal of toxic, injurious or hazardous
    materials, substances or wastes, toxic pollutants or contaminants, including
    petroleum products, crude oil or any by-products or derivatives thereof (as
    any of the foregoing terms are defined in federal, state and local laws
    applicable to the Company or Parent, as the case may be) (collectively,
    "HAZARDOUS MATERIALS"), (B) the control of soil, surface or groundwater
    pollution products, (C) air quality and emission standards, or (D) health,
    safety and hazard communication matters; and (ii) "COMPANY REAL PROPERTIES"
    means all real property ever owned, leased or occupied by the Company or any
    Company Predecessor. For purposes of this Section 3.17, "COMPANY
    PREDECESSOR" shall include the former operating entities of RF Power
    Products, RF Plasma Products and any division or subsidiary of Plasmatherm
    which operated a business at the current Company location, or at either of
    the two previously disclosed locations: 701 Cooper Road, Voorhees, New
    Jersey or 502 Gibbsboro Road, Voorhees, New Jersey.
 
        (b) There has not been any violation of any Environmental Requirements
    by the Company or, to the knowledge of the Company, any Company Predecessor,
    nor to the knowledge of the Company has there been any third party claim or
    demand based upon any Environmental Requirements against the Company or any
    Company Predecessor, other than violations, claims or demands that have not
    resulted, and are not reasonably likely to result, in a Company Material
    Adverse Effect.
 
        (c) The Company has not disposed of, stored or used any Hazardous
    Materials on, nor has it transported any Hazardous Materials from, any of
    the Company Real Properties owned, leased or occupied by the Company, in
    violation of applicable Environmental Requirements other than a disposal,
    storage, use or transport which has not resulted in and is not reasonably
    likely to result in a Company Material Adverse Effect. To the knowledge of
    the Company, no Company Predecessor has disposed of, stored or used any
    Hazardous Materials on, nor has any such Company Predecessor transported any
    Hazardous Materials from, any of the Company Real Properties owned, leased
    or occupied by such Company Predecessor, in violation of applicable
    Environmental Requirements.
 
        (d) To the knowledge of the Company, none of the following exists at any
    of the real property currently owned, leased or occupied by the Company or
    existed at any of the Company Real
 


    Properties at the time the Company or the Company Predecessor operated
    there: (i) underground storage tanks, (ii) asbestos-containing material in
    any friable or damaged form or condition, (iii) materials or equipment
    containing polychlorinated biphenyls (PCBs), or (iv) landfills or surface
    impoundments.
 
        (e) To the knowledge of the Company, none of the Company Real Properties
    is or has been contaminated by any Hazardous Materials, in a manner that has
    given or is reasonably likely to give rise to any material liability on the
    part of the Company to any person, including without limitation any
    governmental authority, for response costs, corrective action costs,
    personal injury, property damage, natural resources damages or attorney
    fees, pursuant to the Comprehensive Environmental Response, Compensation and
    Liability Act of 1980, as amended ("CERCLA"), or the Solid Waste Disposal
    Act, as amended ("SWDA"), or any other Environmental Requirements, whether
    federal, state or locally imposed.
 
                                   ARTICLE 4
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB
 
    Except as set forth in the disclosure schedule delivered at or prior to the
execution hereof to the Company (the "PARENT DISCLOSURE SCHEDULE") or in the
Parent Reports (as defined in Section 4.6) filed with the Commission prior to
the date hereof, Parent and Merger Sub make the following representations and
warranties to the Company as of the date of this Agreement. The term "PARENT
MATERIAL ADVERSE EFFECT" has the meaning given to it in Section 8.14.
 
    4.1.  ORGANIZATION AND STANDING.
 
        (a) Parent and each of its Significant Subsidiaries (i) is a corporation
    duly organized, validly existing and in good standing under the laws of its
    jurisdiction of incorporation, (ii) has all requisite corporate power and
    authority to own, operate and lease its properties and carry on its business
    as now conducted, and (iii) is duly qualified to do business and is in good
    standing as a foreign corporation in each jurisdiction in which the failure
    to so qualify, or be in good standing, would have a Parent Material Adverse
    Effect.
 
        (b) Merger Sub is a corporation duly organized, validly existing and in
    good standing under the laws of its jurisdiction of incorporation. Merger
    Sub was organized for purposes of consummating the transactions contemplated
    by this Agreement. Merger Sub has not engaged in any activity other than as
    provided in, or contemplated by, this Agreement and, as of the date hereof,
    has no liabilities of any nature, contingent or otherwise, other than
    liabilities or obligations that may arise from this Agreement or the
    transactions contemplated hereby. The authorized capital stock of Merger Sub
    consists of 1,000 shares of Merger Sub Common Stock, all of which are
    validly issued, fully paid and nonassessable and are owned by Parent.
 
        (c) Neither Parent nor any of its Subsidiaries (including without
    limitation Merger Sub) has (i) filed or had filed against it a petition in
    bankruptcy or a petition to take advantage of any other insolvency act, (ii)
    admitted in writing its inability to pay its debts generally, (iii) made an
    assignment for the benefit of creditors, (iv) consented to the appointment
    of a receiver for itself or any substantial part of its property or (v)
    generally committed any act of insolvency (including the failure to pay
    obligations as they become due) or bankruptcy.
 
    4.2  CAPITALIZATION.
 
        (a) The authorized capital stock of Parent consists of 30,000,000 shares
    of Parent Common Stock and 1,000,000 shares of preferred stock, par value
    $0.001 per share ("PARENT PREFERRED STOCK"). As of May 31, 1998, there were
    22,542,346 shares of Parent Common Stock, and no shares of Parent Preferred
    Stock, issued and outstanding. From such date to the date of this Agreement,
    no additional shares of capital stock of Parent have been issued, except
    pursuant to the exercise of options to
 


    acquire Parent Common Stock granted by Parent ("PARENT OPTIONS"). As of May
    31, 1998, Parent Options to acquire 1,550,683 shares of Parent Common Stock
    were outstanding. From such date to the date of this Agreement, no
    additional Parent Options have been granted.
 
        (b) All of the issued and outstanding shares of Parent Common Stock have
    been duly authorized and validly issued and are fully paid, nonassessable
    and free of preemptive rights. Other than Parent Options, there are no
    existing and outstanding warrants, rights, options, subscriptions,
    convertible securities or other agreements or commitments which obligate
    Parent to issue, transfer or sell any shares of capital stock of Parent or
    Merger Sub.
 
        (c) All of the shares of Parent Common Stock issuable as consideration
    in the Merger at the Effective Time, when issued in accordance with the
    terms and conditions of this Agreement, will be duly authorized, validly
    issued, fully paid and nonassessable and free of preemptive rights.
 
        (d) Neither Parent nor any of its Subsidiaries (including without
    limitation Merger Sub) has any outstanding bonds, debentures, notes or other
    obligations pursuant to which the holders thereof have the right to vote (or
    which are convertible into or exercisable for securities having the right to
    vote) with the stockholders of Parent on any matter.
 
    4.3.  AUTHORIZATION; ENFORCEABILITY; NO VIOLATION.
 
        (a) Each of Parent and Merger Sub has full corporate power and authority
    to execute and deliver this Agreement, and to perform its respective
    obligations hereunder.
 
        (b) All corporate action necessary on the part of Parent and Merger Sub
    for the execution, delivery and performance of this Agreement has been duly
    taken. No approval of the stockholders of Parent is required by applicable
    law or the rules of the Nasdaq National Market in connection with the
    consummation by Parent or Merger Sub of the transactions contemplated
    hereby.
 
        (c) This Agreement constitutes (assuming this Agreement is a valid and
    binding obligation of the Company), a valid and legally binding obligation
    of each of Parent and Merger Sub, enforceable against Parent and Merger Sub,
    as applicable, in accordance with its terms, subject to the Enforceability
    Exceptions and compliance with ISRA.
 
        (d) The execution, delivery and performance of this Agreement will not
    result in any conflict with, breach or violation of or default (or an event
    which, with notice or lapse of time or both, would constitute a default),
    termination or forfeiture under (i) any terms or provisions of the
    Certificate of Incorporation or the By-laws of Parent or any of its
    Subsidiaries (including without limitation Merger Sub), (ii) any statute,
    rule, regulation, judicial, governmental, regulatory or administrative
    decree, order or judgment applicable to Parent or any of its Subsidiaries
    (including without limitation Merger Sub), or (iii) any agreement, lease,
    license, permit or other instrument to which Parent or any of its
    Subsidiaries (including without limitation Merger Sub) is a party or to
    which any of its assets are subject, except where any such breach,
    violation, default, termination or forfeiture would not have or result in a
    Parent Material Adverse Effect.
 
        (e) There is no action, suit, proceeding or investigation pending or
    threatened against Parent or any of its Subsidiaries that questions the
    validity of this Agreement or the right of Parent or Merger Sub to enter
    into this Agreement or to consummate the transactions contemplated hereby.
 
    4.4.  NO CONSENTS.  No consent, approval, authorization, order,
registration, qualification or filing of or with any court or any regulatory
authority or any other governmental or administrative body is required on the
part of Parent or any of its Subsidiaries for the consummation by Parent and
Merger Sub of the transactions contemplated by this Agreement, except (i)
filings required in order to comply with the HSR Act, (ii) notices and filings
required in order to comply with the Securities Act, the Exchange Act and state
securities or "blue sky" laws, (iii) the filing of the Certificate of Merger
with the New Jersey Secretary of State, and (iv) as may be required by ISRA.
 


    4.5.  COMPLIANCE WITH LAWS.  Except where the failure to so comply would not
have a Parent Material Adverse Effect, Parent and each of its Subsidiaries (i)
have all valid and current Permits, and each Permit is in full force and effect,
and (ii) have made all filings and registrations and the like, necessary or
required by law to conduct their respective businesses as currently conducted.
Neither Parent nor any of its Subsidiaries has received any governmental notice
of any violation by such company of any laws, rules, regulation or orders
applicable to their respective businesses, which violation in the case of any
Subsidiary is reasonably likely to have a Parent Material Adverse Effect. Except
where the failure to comply would not have a Parent Material Adverse Effect, (a)
neither Parent nor any of its Subsidiaries is in default or is not in compliance
under any Permits, and (b) the business and operations of each of Parent and its
Subsidiaries are in compliance with all applicable foreign, federal, state,
local and county laws, ordinances, regulations, judgments, orders, decrees or
rules of any court, arbitrator or governmental, regulatory or administrative
agency or entity.
 
    4.6.  PARENT REPORTS.
 
        (a) Parent has filed all reports, forms, registrations, schedules,
    statements and other documents required to be filed by it with the
    Commission since November 17, 1995 (the "PARENT REPORTS"). As of their
    respective dates, the Parent Reports complied as to form in all material
    respects with the requirements of the Securities Act or the Exchange Act, as
    the case may be, and the applicable rules and regulations promulgated
    thereunder. Except to the extent that information contained in any Parent
    Report has been amended, revised or superseded by a Parent Report
    subsequently filed and publicly available prior to the date of this
    Agreement, none of the Parent Reports, when filed, contained any untrue
    statement of a material fact or omitted 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.
 
        (b) Each of the consolidated balance sheets of Parent included in or
    incorporated by reference into the Parent Reports (including the related
    notes and schedules) fairly presents in all material respects the
    consolidated financial position of Parent and its Subsidiaries as of its
    date, and each of the consolidated statements of income, stockholders'
    equity and cash flows of Parent included in or incorporated by reference
    into the Parent Reports (including any related notes and schedules) fairly
    presents in all material respects the income, stockholders' equity and cash
    flows, as the case may be, of Parent and its Subsidiaries for the periods
    set forth therein (subject, in the case of unaudited statements, to normal
    year-end audit adjustments which would not be material in amount or effect),
    in each case in accordance with GAAP, except as may be noted therein and
    subject to the fact that unaudited financial statements do not contain full
    notes thereto. Parent and its Subsidiaries do not have any liabilities or
    obligations required to be disclosed in a consolidated balance sheet or the
    notes thereto prepared in accordance with GAAP, except (i) liabilities or
    obligations reflected on, or reserved against in, a consolidated balance
    sheet of Parent or in the notes thereto, and included in the Parent Reports,
    (ii) liabilities or obligations incurred since March 31, 1998 in the
    ordinary course of business, consistent with past practices, or (iii)
    liabilities disclosed in a Parent Report.
 
    4.7.  ABSENCE OF LITIGATION, ORDERS, JUDGMENTS.
 
        (a) There are no actions, suits or proceedings pending or, to the
    knowledge of Parent, threatened which involve transactions of or otherwise
    relate to Parent or any of its Subsidiaries or any of such companies'
    businesses or properties, at law or in equity, or before any arbitrator of
    any kind, or before or by any federal, state, municipal or other
    governmental department, commission, board, bureau, agency or other
    instrumentality, domestic or foreign, that are reasonably likely to have a
    Parent Material Adverse Effect.
 
        (b) There are no outstanding orders, writs, injunctions, decrees,
    judgments, awards, determinations or directions, which involve transactions
    of or otherwise relate to Parent or any of its Subsidiaries or any of such
    companies' businesses or properties, of any court or arbitrator or under any
    outstanding order, regulation or demand of any federal, state, municipal or
    other governmental instrumentality, domestic or foreign, that are reasonably
    likely to have a Parent Material Adverse Effect.
 
 

    4.8.  ABSENCE OF CERTAIN CHANGES.  Since March 31, 1998, Parent and its
Subsidiaries have conducted their businesses only in the ordinary course of such
businesses, except for any action conducted outside the ordinary course of
business which is not reasonably likely to result in a Parent Material Adverse
Effect, and there has not been (i) any Parent Material Adverse Effect or any
event which is reasonably likely to result in a Parent Material Adverse Effect;
(ii) any declaration, setting aside or payment of any dividend or other
distribution with respect to its capital stock; or (iii) any material change in
its accounting principles, practices or methods.
 
    4.9.  TAXES.  Parent (a) has timely filed all material federal, state and
foreign tax returns required to be filed by it for tax years ended prior to the
date of this Agreement or requests for extensions have been timely filed and any
such request shall have been granted and not expired, and all such returns are
complete in all material respects, (b) has paid or accrued all taxes shown to be
due and payable on such returns and (c) has properly accrued all such taxes for
such periods subsequent to the periods covered by such returns.
 
    4.10.  CONTRACTS.  Each (a) agreement, contract and commitment, whether
written or oral, to which Parent or any of its Subsidiaries is a party or by
which any of such companies is bound and which is filed as an exhibit to or
described in a Parent Report, and (b) agreement, contract and commitment that is
material to Parent and its Subsidiaries taken as a whole and that was entered
into by Parent or any of its Subsidiaries, or by which such company became
bound, after the date of the Quarterly Report on Form 10-Q most recently filed
by Parent (collectively, "PARENT CONTRACTS"), is a valid and legally binding
obligation of Parent or the Subsidiary party thereto and, to the knowledge of
Parent, the other parties thereto, enforceable against Parent or the Subsidiary
party thereto and, to the knowledge of Parent, the other parties thereto, in
accordance with its terms, subject to the Enforceability Exceptions. Neither
Parent nor any Subsidiary party to a Parent Contract is in material default of
such Parent Contract, and, to the knowledge of Parent, no other party to a
Parent Contract is in material default of such Parent Contract. Neither Parent
nor any Subsidiary party to a Parent Contract has performed any act or omitted
to perform any act which act or omission, with the giving of notice or passage
of time or otherwise, will become a material default thereunder. To the
knowledge of Parent, no other party to a Parent Contract has performed any act
or omitted to perform any act which act or omission, with the giving of notice
or passage of time or otherwise, will become a material default thereunder.
 
    4.11.  INTELLECTUAL PROPERTY.
 
        (a) Parent and its Subsidiaries own or have the right to use all
    Intellectual Property used by them in the operation of their respective
    businesses, except to the extent that the failure to have such rights has
    not and is not reasonably likely to result in (i) a material adverse effect
    on Parent's or its Subsidiaries' ability to manufacture or sell any product
    or line of products that is material to Parent and its Subsidiaries, taken
    as a whole, (ii) a material adverse effect on Parent's or any of its
    Subsidiaries' ability to operate its businesses, which inability to so
    operate would have a Parent Material Adverse Effect, (iii) a liability of
    Parent or any of its Subsidiaries, which liability would have a Parent
    Material Adverse Effect, or (iv) material redesign or other corrective costs
    to Parent or any of its Subsidiaries, which costs would be material to
    Parent and its Subsidiaries, taken as a whole. Parent and its Subsidiaries
    have taken reasonably necessary action to maintain and protect their rights
    in the material Intellectual Property that they own or use.
 
        (b) Parent has not, within the past four years, interfered with,
    infringed upon, misappropriated or otherwise come into conflict with any
    Intellectual Property rights of others, other than any interference,
    infringement, misappropriation or conflict with did not and is not
    reasonably likely to result in (i) a material adverse effect on Parent's or
    its Subsidiaries' ability to manufacture or sell any product or line of
    products that is material to Parent and its Subsidiaries, taken as a whole,
    (ii) a material adverse effect on Parent's or any of its Subsidiaries'
    ability to operate its businesses, which inability to so operate would have
    a Parent Material Adverse Effect, (iii) a liability of Parent or any of its
    Subsidiaries, which liability would have a Parent Material Adverse Effect,
    or (iv) material redesign
 


    or other corrective costs to Parent or any of its Subsidiaries, which costs
    would be material to Parent and its Subsidiaries, taken as a whole. Parent
    has not received, and has no knowledge of, any charge, complaint, claim,
    demand or notice alleging any such interference, infringement,
    misappropriation or conflict by Parent or any of its Subsidiaries.
 
        (c) To the knowledge of Parent, no fraud or misrepresentation has been
    made by (i) Parent or any of its Subsidiaries, (ii) any of their respective
    officers, directors or employees or (iii) the relevant inventors during the
    prosecution of any of the Patents of Parent or any of its Subsidiaries, nor
    has any fraud or misrepresentation been included in any documentation for or
    other disclosure of the Intellectual Property of Parent or any of its
    Subsidiaries.
 
    4.12  EMPLOYEE BENEFIT PLANS.
 
        (a) For purpose of this Agreement, (i) "PARENT BENEFIT PLANS" means all
    employee benefit plans and other benefit arrangements covering employees or
    former employees of Parent and its Subsidiaries and all employee agreements
    providing compensation, severance or other benefits to any employee or
    former employee of Parent or one of its Subsidiaries.
 
        (b) With respect to each Parent Benefit Plan that is intended to be a
    "qualified plan" within the meaning of Section 401(a) of the Code, either
    (i) the IRS has issued a favorable determination letter that has not been
    revoked, or (ii) an application for a favorable determination letter was
    timely submitted to the IRS for which no final action has been taken by the
    IRS. To the knowledge of Parent, there is no reason that is not susceptible
    to cure why the qualified status under Section 401(a) of the Code of any
    Parent Benefit Plan would be denied or revoked, whether retroactively or
    prospectively.
 
        (c) Except as would not have a Parent Material Adverse Effect, no Parent
    Benefit Plan, any fiduciary thereof, nor Parent has incurred any liability
    or penalty under Section 4975 of the Code or Section 502(i) of ERISA. Except
    as would not have a Parent Material Adverse Effect, each Parent Benefit Plan
    has been maintained and administered in all material respects in compliance
    with its terms and with ERISA and the Code, to the extent applicable
    thereto.
 
        (d) Except as would not have a Parent Material Adverse Effect, neither
    Parent nor any ERISA Affiliate (during the period of its affiliated status)
    has any existing liability currently due and payable that has not been
    satisfied in full under Title IV of ERISA or Section 412 of the Code. To the
    knowledge of Parent, there are no current plans to terminate, whether
    voluntarily or involuntarily any materially underfunded pension plans of
    Parent or any ERISA Affiliate that are subject to Title IV of ERISA.
 
        (e) Except as would not have a Parent Material Adverse Effect, to the
    knowledge of Parent, there are no pending or anticipated claims against or
    otherwise involving any of the Parent Benefit Plans and no suit, action or
    other litigation (excluding claims for benefits incurred in the ordinary
    course of the Parent Benefit Plan activities) has been brought against or
    with respect to any such Parent Benefit Plan, except for any of the
    foregoing which would not have a Parent Material Adverse Effect.
 
        (f) All material contributions required to be made as of the date hereof
    to the Parent Benefit Plans have been made or provided for.
 
        (g) The execution of, and performance of the transactions contemplated
    by, this Agreement will not (either alone or upon the occurrence of any
    additional or subsequent events) constitute an event under any benefit plan,
    policy, arrangement or agreement or any trust or loan that will or may
    result in any payment (whether of severance pay or otherwise), acceleration,
    forgiveness of indebtedness, vesting, distribution, increase in benefits or
    obligation to fund benefits with respect to any employee of Parent or any of
    its Subsidiaries.
 


    4.13.  NO BROKERS.  Neither Parent nor any of its Subsidiaries has entered
into any contract, arrangement or understanding with any person or firm which
will or is reasonably likely to result in the obligation of the Company, Parent
or Merger Sub to pay any finder's fees, brokerage or agent's commissions or
other like payments in connection with the negotiations leading to this
Agreement or the consummation of the transactions contemplated hereby, except
that Parent has retained PaineWebber Incorporated as its financial advisor, the
arrangements with which have been disclosed in writing to the Company prior to
the date hereof. Other than the foregoing arrangements, Parent is not aware of
any claim for payment of any finder's fees, brokerage or agent's commissions or
other like payments in connection with the negotiations leading to this
Agreement or the consummation of the transactions contemplated hereby.
 
    4.14.  COMPANY STOCK OWNERSHIP.  Neither Parent nor any of its Subsidiaries
owns any shares of Company Common Stock or other securities convertible into
Company Common Stock.
 
    4.15.  POOLING OF INTERESTS; TAX REORGANIZATION.  To the knowledge of
Parent, having sought and obtained the advice of its accounting advisors,
neither Parent nor any of its Subsidiaries has taken (or as of the date hereof
failed to take) any action which would prevent the accounting for the Merger as
a pooling of interests in accordance with APB No. 16, the interpretative
releases issued pursuant thereto, and the pronouncements of the Commission. To
the knowledge of Parent, neither Parent nor any of its Subsidiaries has taken or
failed to take any action which would prevent the Merger from constituting a
reorganization within the meaning of section 368 of the Code.
 
    4.16.  ENVIRONMENTAL MATTERS.
 
        (a) For purposes of this Agreement, "PARENT REAL PROPERTIES" means all
    real property ever owned, leased or occupied by Parent or any of its
    Subsidiaries or any predecessor to their businesses (each, a "PREDECESSOR").
 
        (b) There has not been any violation of any Environmental Requirements
    by Parent or any of its Subsidiaries or, to the knowledge of Parent, any
    Predecessor, nor to the knowledge of Parent has there been any third party
    claim or demand based upon any Environmental Requirements against Parent or
    any or its Subsidiaries or any Predecessor, other than violations, claims or
    demands that have not resulted, and are not reasonably likely to result in,
    a Parent Material Adverse Effect.
 
        (c) Neither Parent nor any of its Subsidiaries has disposed of, stored
    or used any Hazardous Materials on, nor has any of such companies
    transported any Hazardous Materials from, any of the Parent Real Properties
    owned, leased or occupied by Parent or any of its Subsidiaries, in violation
    of applicable Environmental Requirements, other than a disposal, storage,
    use or transport which has not resulted in and is not reasonably likely to
    result in a Parent Material Adverse Effect. To the knowledge of Parent, no
    Predecessor has disposed of, stored or used any Hazardous Materials on, nor
    has any Predecessor transported any Hazardous Materials from, any of the
    Parent Real Properties owned, leased or occupied by such Predecessor, in
    violation of applicable Environmental Requirements.
 
        (d) To the knowledge of Parent, none of the following exists at any of
    the Parent Real Properties: (i) underground storage tanks, (ii)
    asbestos-containing material in any friable or damaged form or condition,
    (iii) materials or equipment containing polychlorinated biphenyls (PCBs), or
    (iv) landfills or surface impoundments.
 
        (e) To the knowledge of Parent, none of the Parent Real Properties is or
    has been contaminated by any Hazardous Materials, in a manner that has given
    or is reasonably likely to give rise to any material liability on the part
    of Parent or any of its Subsidiaries to any person, including without
    limitation any governmental authority, for response costs, corrective action
    costs, personal injury, property damage, natural resources damages or
    attorney fees, pursuant to CERCLA or SWDA or any other Environmental
    Requirements, whether federal, state or locally imposed.

    equity interest in, the Company or any business combination with the
    Company.
 
        (b) Prior to the Closing Date, the Company may, solely in response to
    unsolicited requests therefor, furnish non-public information regarding
    itself to any corporation, partnership, person or other entity or group in
    respect of, and may participate in discussions and negotiate with such
    entity or group concerning, a business combination, merger, sale of material
    assets, sale of shares of capital stock or similar transaction involving the

    submitted a written proposal to the Board of Directors of the Company
    relating to any such Transaction (an "ALTERNATIVE PROPOSAL"), (ii) the
    entity or group enters into confidentiality agreements with the Company with
    respect to such non-public information, and (iii) the Board of Directors of
    the Company ("COMPANY BOARD"), by a majority vote, determines in its good
    faith judgment, based as to legal matters on the advice of legal counsel,
    that failing to take such action would constitute a breach of the Company
    Board's fiduciary duty. The Company Board shall provide a copy of any such
    written proposal to Parent and Merger Sub immediately after receipt thereof,
    unless prohibited by the terms of such proposal.
 
        (c) Neither the Company nor any of its affiliates, nor any of such
    persons' respective officers, directors, employees, representatives or

    or any designees of Parent and Merger Sub) concerning any Transaction, or
    (ii) authorize, propose or announce an intention to authorize or propose any
    Transaction (other than the Merger), unless and until the Company has
    received an Alternative Proposal in writing and the Company Board, by
    majority vote, has determined in its good faith judgment, based as to legal
    matters on the advice of legal counsel, that failing to take such action
    would constitute a breach of the Company Board's fiduciary duty; PROVIDED,
    HOWEVER, that nothing herein shall prevent the Company Board from taking,
    and disclosing to the Company's stockholders, a position contemplated by
    Rules 14d-9 and 14e-2 promulgated under the Exchange Act with regard to any
    tender offers; PROVIDED, FURTHER, that the Company Board shall not recommend
    that the stockholders of the Company tender their shares in connection with
    any such tender offer unless the Company Board by a majority vote determines
    in its good faith judgment, based as to legal matters on the advice of legal
    counsel, that failing to take such action would constitute a breach of the
    Company Board's fiduciary duty.
 
        (d) Nothing in this Section 5.1 shall (i) permit the Company to
    terminate this Agreement (except as specifically provided in Article 7
    hereof), (ii) permit the Company to enter into any agreement with respect to
    a Transaction during the term of this Agreement (it being agreed that during

    other than a confidentiality agreement in customary form), or (iii) affect
    any other obligation of the Company under this Agreement.

       release or
 


       relinquishment of any contract rights, which acquisitions, dispositions,

            (xi) shall not incur, create, assume or otherwise become liable for

       agree, in writing or otherwise, to take any of the foregoing actions or

in accordance with applicable law and its Certificate of Incorporation and
Bylaws to convene a meeting of its stockholders (the "STOCKHOLDERS' MEETING") as

    any other transactions contemplated by this Agreement, except that neither
    Parent nor the Company nor any of its respective Subsidiaries shall be
    required, by this paragraph (b) or otherwise, to sell, hold separate or
    divest any of its (or any its Subsidiaries' or affiliates) businesses,

    action) in order to resolve any such objections. If any administrative,
    judicial or legislative action or proceeding is instituted (or threatened to
    be instituted) challenging the Merger or any other transactions contemplated
    hereby as violative of any Antitrust Law, the parties shall cooperate and
    use their best efforts vigorously to contest and resist any such action or
    proceeding, and to have vacated, lifted, reversed or overturned any decree,
    judgment, injunction or other order (whether temporary, preliminary or
    permanent) that is in effect and that restricts, prevents or prohibits
    consummation of the Merger or any other transaction contemplated by this
    Agreement, including without limitation by vigorously pursuing all available
    avenues of administrative and judicial appeal and legislative action.
 
        (c) Each of the Company, Parent and Merger Sub shall promptly inform the
    other parties of any material communication received by such party from the

    the transactions contemplated hereby. Parent and Merger Sub will advise the
    Company promptly in respect of any understandings, undertakings or
    agreements which Parent or Merger Sub propose to make or enter into with the
    Federal Trade Commission, the Antitrust Division of the Department of
    Justice or any other governmental or regulatory authority regarding any of
    the transactions contemplated hereby.
 
        (d) "ANTITRUST LAW" means the Sherman Act, as amended, the Clayton Act,
    as amended, the HSR Act, the Federal Trade Commission Act, as amended, and
    all other federal, state and foreign statutes, rules, regulations, orders,
    decrees, administrative and judicial doctrines and other laws that are
    designed or intended to prohibit, restrict or regulate actions having the

and similar self regulatory bodies), consult with each other, and use reasonable
efforts to agree upon the text of any press release, before issuing any such
press release or otherwise
 


making public statements with respect to the transactions contemplated hereby
and in making any filings with any federal or state governmental or regulatory
agency or with any national securities exchange with respect thereto.

        (a) Parent and the Company shall cooperate and promptly prepare and
    Parent shall file with the Commission as soon as practicable a Registration
    Statement on Form S-4 under the Securities Act (the "REGISTRATION
    STATEMENT"), with respect to the Parent Common Stock issuable in the Merger,
    which Registration Statement shall contain the proxy statement with respect
    to the meeting of the stockholders of the Company in connection with the
    Merger (the "PROXY STATEMENT/PROSPECTUS"). Notwithstanding the foregoing,
    the Company and Parent may elect to file the Proxy Statement/ Prospectus
    pursuant to Section 14 of the Exchange Act on a confidential basis and to
    receive, respond to and clear all Commission comments thereon, prior to
    filing the Registration Statement.
 
        (b) The parties will cause the Proxy Statement/Prospectus, and Parent
    will cause the Registration Statement, to comply as to form in all material
    respects with the applicable provisions of the Securities Act, the Exchange
    Act and the rules and regulations thereunder. Parent shall use all
    reasonable efforts, and the Company shall cooperate with Parent, (i) to have
    the Registration Statement declared effective by the Commission as promptly
    as practicable, and (ii) to obtain timely any and all necessary state
    securities or "blue sky" permits or approvals required to carry out the
    transactions contemplated by this Agreement.

    any amendment thereof or supplement thereto) is first mailed to holders of
    Company Common Stock, (iii) at the time of the Stockholders' Meeting, and
    (iv) at the Effective Time, contain any untrue statement of a material fact
    or omit to state a material fact required to be stated therein or necessary
    to make the statements therein, in the light of the circumstances under
    which they are made, not misleading.

    reference in the Proxy Statement/Prospectus and the Registration Statement
    shall not (i) at the time the Registration Statement is declared effective,
    (ii) at the time the Proxy Statement/Prospectus (or any amendment thereof or
    supplement thereto) is first mailed to holders of Company Common Stock,
    (iii) at the time of the Stockholders' Meeting, and (iv) at the Effective
    Time, contain any untrue statement of a material fact or omit to state a
    material fact required to be stated therein or necessary to make the
    statements therein, in the light of the circumstances under which they are
    made, not misleading.
 
        (e) No amendment or supplement to the Proxy Statement/Prospectus will be
    made by the Company or Parent without the approval of the other. Parent will
    advise the Company, promptly after it receives notice thereof, of the time
    when the Registration Statement has become effective or any supplement or
    amendment has been filed, the issuance of any stop order, the suspension of
    the qualification of the Parent Common Stock issuable in connection with the
    Merger for offering or sale in any jurisdiction, or any request by the
    Commission for amendment of the Proxy Statement/ Prospectus or the
    Registration Statement or comments thereon and responses thereto or requests
    by the Commission for additional information.
 
    5.10.  LISTING APPLICATION.  Parent shall promptly prepare and submit to the
Nasdaq National Market a listing application covering the shares of Parent
Common Stock issuable in the Merger, and shall use its best efforts to obtain,
prior to the Effective Time, approval for the listing of such Parent Common
Stock, subject to official notice of issuance.
 
    5.11.  AFFILIATE LETTERS.  At least 30 days prior to the Closing Date, the
Company shall deliver to Parent a list of names and addresses of those persons
who were, in the Company's reasonable judgment, as
 


of the record date for the Stockholders' Meeting, "affiliates" of the Company
within the meaning of Rule 145 of the rules and regulations promulgated under
the Securities Act (each such person, an "AFFILIATE"). The Company shall provide
Parent such information and documents as Parent shall reasonably request for
purposes of reviewing such list. The Company shall use all reasonable efforts to
deliver or cause to be delivered to Parent, prior to the Closing Date, from each
of the Affiliates of the Company identified in the foregoing list, an affiliate
letter in form and substance reasonably acceptable to the Company and Parent
(collectively, "AFFILIATE LETTERS"). Parent shall be entitled to place legends
as specified in such Affiliate Letters on the certificates evidencing any Parent
Common Stock to be received by such Affiliates pursuant to the terms of this
Agreement, and to issue appropriate stop transfer instructions to the transfer
agent for the Parent Common Stock, consistent with the terms of such Affiliate
Letters.
 
    5.12.  EXPENSES.  Whether or not the Merger is consummated, all costs and

Commission and the expenses incurred in connection with printing and mailing the
Registration Statement and the Proxy Statement/Prospectus shall be shared
equally by the Company and Parent.
 
    5.13.  EMPLOYEE BENEFITS.
 
        (a) For a period of two years following the Effective Time, Parent shall
    provide to persons who are employees of the Company at the Effective Time
    (the "COMPANY PERSONNEL") employee compensation and benefit plans, programs
    and arrangements which collectively for the Company Personnel, as a whole,
    are in the aggregate substantially comparable to the employee compensation
    and benefit plans, programs and arrangements generally provided to the
    employees of the Company immediately prior to the Effective Time; PROVIDED,
    HOWEVER, that subject to the foregoing, Parent shall not be precluded from
    amending or terminating any particular plan, program or arrangement, or from
    substituting any such plans, programs or arrangements with plans, programs
    or arrangements applicable and available to other employees of Parent and
    its Subsidiaries.
 
        (b) Following the Effective Time, Parent shall cause the benefit plans
    covering the Company Personnel following the Effective Time (the "BENEFIT
    PLANS") to continue to recognize the service credit of the Company Personnel
    accrued as of the Effective Time under the Company Benefit Plans for
    purposes of participation, eligibility and vesting of benefits, to the
    extent permissible by the terms of such Benefit Plans.
 
        (c) In the event of any change in coverage that applies generally to the
    Company Personnel during the two-year period following the Effective Time
    under any Benefit Plan that provides medical or health benefits, Parent
    shall (i) cause such Benefit Plan to recognize credit toward satisfying
    deductible expense requirements, out-of-pocket expense limits and maximum
    lifetime benefit limits of such Company Personnel or their eligible
    dependents, (ii) waive any pre-existing condition, exclusion or limitation,
    as and to the extent any such matter would previously have been recognized
    or waived (as the case may be) under the applicable Company Benefit Plan,
    and (iii) waive any waiting period or minimum service requirements.
 
    5.14.  AGREEMENTS.  Between the date hereof and the Closing Date, neither
Parent nor the Company shall enter into any agreement which Parent or the
Company, as the case may be, knows or has reason to know is reasonably likely to
cause any major customer of Parent or the Company (or their respective
subsidiaries) to terminate any material contracts, agreements or other
obligations that exist between that customer on the one hand, and Parent, the
Company (or Parent and the Company following the Merger) or any subsidiary of
either, on the other hand and Parent and the Company shall take all reasonable
action appropriate to an effort to avoid such termination.
 
    5.15.  TAKEOVER STATUTE.  If any "fair price," "moratorium," "control share
acquisition" or other form of anti-takeover statute or regulation shall become
applicable to the transactions contemplated hereby, the
 


Company and the Company Board shall grant such approvals and take such actions
as are reasonably necessary so that the transactions contemplated hereby may be
consummated as promptly as practicable on the terms contemplated hereby and
otherwise act to eliminate or minimize the effects of such statute or regulation
on the transactions contemplated hereby; PROVIDED, HOWEVER, that the Company and
the Company Board shall not be required to grant such approvals or take such
actions if the Company Board, by majority vote, determines in its good faith
judgment, based as to legal matters on the advice of legal counsel, that
granting such approvals or taking such actions would constitute a breach of the
Company's Board's fiduciary duties.

    directors of the Company, Company Personnel and other persons specified
    therein, including without limitation Article VII of the Bylaws of the
    Company (collectively, the "INDEMNIFICATION PROVISIONS"), which provisions
    shall not be amended, repealed or otherwise modified for a period of six
    years from the Effective Time in any manner that would affect adversely the
    rights thereunder with respect to actions or events occurring prior to the
    Effective Time of individuals who were entitled to such indemnification
    prior to the Effective Time.
 
        (b) The Surviving Corporation shall maintain in effect for at least six
    years from the Effective Time directors' and officers' liability insurance
    with an insurance company rated at least "A" by A.M. Best Company, covering
    the persons who, as of the date of this Agreement, are covered by the
    Company's directors' and officers' liability insurance policy (the "CURRENT
    POLICY"). The coverage provided by the directors' and officers' liability
    insurance maintained by the Surviving Corporation shall be substantially
    similar to the coverage provided by the Current Policy.
 
        (c) Parent shall guarantee the obligations of the Surviving Corporation
    provided by this Section 5.16.
 
        (d) This Section 5.16 shall survive the consummation of the Merger, is
    intended to benefit the Company, the Surviving Corporation and each
    indemnified party, and shall be enforceable by the indemnified parties.

    voting stock, then the Company shall pay Parent, by wire transfer of
    immediately available funds, a fee (the "TERMINATION FEE") of Two Million
    Dollars ($2,000,000) within two (2) business days after the execution of
    such agreement or the consummation of such acquisition (whichever shall
    first occur).
 
        (b) The Company acknowledges that the agreements contained in this
    Section 7.5 are an integral part of the transactions contemplated in this
    Agreement, and that, without these agreements, Parent and Merger Sub would
    not enter into this Agreement; accordingly, if the Company fails to promptly
    pay the Termination Fee when due and, in order to obtain such payment,
    Parent or Merger Sub commences a suit which results in a judgment against
    the Company, the Company shall reimburse Parent for its costs and expenses
    (including reasonable attorneys' fees) incurred in connection with such
    suit, together with interest on the amount of the Termination Fee at the
    prime rate, as then quoted in THE WALL STREET JOURNAL, from the date the
    Termination Fee was required to be paid.
 
        (c) In the event of termination of this Agreement and the abandonment of
    the Merger pursuant to this Article 7, all obligations of the parties hereto
    shall terminate, except (i) the obligations of the parties set forth in this
    Section 7.5 and Section 5.12, (ii) the provisions of Sections 8.3, 8.6, 8.9
    and 8.13, and (iii) the Confidentiality Agreement previously executed
    between the Company and Parent (the "CONFIDENTIALITY AGREEMENT"). Moreover,
    in the event of termination of this Agreement pursuant
 


    to Section 7.3 or 7.4, nothing herein shall prejudice the ability of the
    nonbreaching party from seeking damages, after taking into account payment
    of the Termination Fee, if such fee has been paid, from any other party for
    any willful breach of this Agreement, including without limitation,
    attorneys' fees and the right to pursue any remedy at law or in equity.
 
    7.6.  EXTENSION; WAIVER.  At any time prior to the Effective Time, any party
hereto, by action taken by its Board of Directors, may, to the extent legally
allowed, (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto and (c) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. 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.

parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties. Subject to the preceding sentence, this
Agreement shall be binding upon and shall inure to the benefit of the parties

intended to confer on any person other than the parties hereto or their
respective heirs, successors, executors, administrators and assigns any rights,

    8.4.  ENTIRE AGREEMENT.  This Agreement, the Exhibits, the Company
Disclosure Schedule, the Parent Disclosure Schedule, the Confidentiality
Agreement and any documents delivered by the parties in connection herewith

this Agreement shall be binding upon any party hereto unless made in writing and
signed by all parties hereto.
 
    8.5.  AMENDMENT.  This Agreement may be amended by the parties hereto, by
action taken by their respective Boards of Directors, at any time before or
after approval of the Merger by the stockholders of the Company, but after any
such stockholder approval, no amendment shall be made which by law requires the
further approval of stockholders without obtaining such further approval. This
Agreement may not be amended except by an instrument in writing signed on behalf
of each of the parties hereto.
 
    8.6.  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of New Jersey without regard to its rules
of conflict of laws.
 
    8.7.  COUNTERPARTS.  This Agreement may be executed by the parties hereto in
separate counterparts, each of which when so executed and delivered shall be an

versa, and words denoting any gender shall include all genders and words

    8.10.  WAIVERS.  Except as provided in this Agreement, no action taken
pursuant to this Agreement, including, without limitation, any investigation by
or on behalf of any party, shall be deemed to constitute a waiver by the party
taking such action of compliance with any representations, warranties, covenants
or agreements contained in this Agreement. The waiver by any party hereto of a
breach of any provision hereunder shall not operate or be construed as a waiver
of any prior or subsequent breach of the same or any other provision hereunder.

Parent Disclosure Schedule and all Exhibits attached hereto and referred to
herein are hereby incorporated herein and made a part hereof for all purposes as

    8.12.  SEVERABILITY.  Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.
 
    8.13.  ENFORCEMENT OF AGREEMENT.  The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement was
not performed in accordance with its specific terms or was otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or
