ITEM 5.  OTHER EVENTS

     On June 2, 1998, RF Power Products, Inc., a New Jersey corporation ("RF
Power"), and Advanced Energy Industries, Inc., a Delaware corporation ("Advanced
Energy"), issued a joint press release announcing that they had entered into an
Agreement and Plan of Reorganization dated as of  June 1, 1998.  A copy of the
agreement (the "Merger Agreement") is attached hereto as Exhibit 2.1 and is
incorporated herein by reference.

     The Merger Agreement, which is among Advanced Energy, RF Power and
Warpspeed, Inc. ("Advanced Energy Merger Sub"), a New Jersey corporation and
wholly-owned subsidiary of Advanced Energy, provides for the merger (the
"Merger") of Advanced Energy Merger Sub with and into RF Power, with RF Power
surviving as a wholly-owned subsidiary of Advanced Energy.  Pursuant to the
Merger Agreement, each share of common stock, par value $.01 per share, of RF
Power ("RF Power Common Stock") issued and outstanding immediately prior to the
Effective Time (as defined in the Merger Agreement) of the Merger will, 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 $.001 per share, of Advanced Energy ("Advanced Energy Common Stock"), that
is equal to 3,750,000 divided by the number of shares of RF Power Common Stock
issued and outstanding immediately prior to the Effective Time (the "Exchange
Ratio"); provided, however, that (A) if the Closing Price (as defined below) of
Advanced Energy Common Stock 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 RF Power 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 Advanced Energy
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 meeting of the stockholders of RF Power for the purpose of
considering and voting upon the approval of the Merger Agreement and the
transactions contemplated thereby.  "Trading Day" means a day on which trading
is conducted on the Nasdaq National Market.

     The Merger Agreement has been approved by the respective Boards of
Directors of Advanced Energy and RF Power.  The consummation of the Merger is
subject, among other things, to the approval of the Merger by the stockholders
of RF Power and to Hart-Scott-Rodino antitrust clearance.  The Merger is
expected to be accounted for using the pooling of interests method of accounting
and to be a tax-free reorganization.

the terms and subject to the conditions set forth herein.

interests for financial accounting purposes.

           ----------------

value $0.01 per share, of the Company ("Company Common Stock") that is issued

divided by the number of shares of Company Common Stock issued and outstanding
immediately prior to the Effective Time (the "Exchange Ratio"); provided,

the result obtained by dividing, $5.06 by the Closing Price, but in no event

                                       2
<PAGE>
 
pursuant to this clause (B) be less than 3,500,000 divided by the Effective Time

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 

                                       3
<PAGE>
 
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.

                                       4
<PAGE>
 
     (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 

                                       5
<PAGE>
 
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.

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

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

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

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

     (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

                                       12
<PAGE>
 
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.

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

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.

any severance policies applicable to the Company or its employees.

of the transactions contemplated hereby, except that the Company has retained
NationsBanc Montgomery Securities LLC as its financial advisor, the arrangements

finder's fees, brokerage or agent's commissions or other like payments in

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

Commission.  To the knowledge of the Company, the Company has not taken or

effect, and (ii) have made all filings and registrations and the like, necessary

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

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

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,

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

the Parent Benefit Plans have been made or provided for.

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.

all or any material portion of the assets of, or any 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 Company (a
"Transaction"), provided that (i) such entity or group has 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 agents, shall,

corporation, partnership, person or other entity or group (other than Parent and
Merger Sub, any affiliate or associate of Parent and Merger Sub 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 the term of this
Agreement, the Company shall not enter into any agreement with any person that
provides for, or in any way facilitates, a Transaction, other than a

particular plan, program or arrangement, or from substituting any such plans,

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)

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

agreements set forth in this Agreement on the part of the Company, which breach
is not curable or, if curable, is not cured within 30 days after written notice

     7.5.   Effect of Termination and Abandonment.
            ------------------------------------- 

            (a) If this Agreement is terminated by the Company or Parent
pursuant to Section 7.2(b), 7.3(a) or 7.4(a), and (x) prior to such termination,
a proposal with respect to a Transaction shall have been made, and (y) within
six (6) months after such termination, either the Company enters into any
agreement with respect to a Transaction, or any third party shall acquire
beneficial ownership of 50.1% or more of the Company's outstanding shares of
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.

FOR IMMEDIATE RELEASE:
TUESDAY, JUNE 2, 1998


            ADVANCED ENERGY INDUSTRIES TO ACQUIRE RF POWER PRODUCTS
                             IN EXCHANGE OF STOCK

  Merger Will Add Approximately $34 Million to Advanced Energy's Revenue Base


FORT COLLINS, CO/VOORHEES, NJ - June 2, 1998 - Advanced Energy Industries, Inc. 
(Nasdaq:AEIS) today announced that it has agreed to acquire RF Power Products, 
Inc. (ASE:RFP) in an exchange of stock.  RF Power Products shareholders will 
receive between 3,500,000 and 4,000,000 shares of common stock in Advanced 
Energy with an aggregate value of approximately $55.0 million depending upon the
price of Advanced Energy stock at the time of closing, subject to specified 
adjustments. A definitive agreement has been approved by the board of directors 
of both companies. Consummation of the transaction is subject to approval by RF 
Power Products shareholders, antitrust clearances and certain other conditions. 
RF Power Products' fiscal 1997 revenues were $33.8 million.

The acquisition is expected to be accounted for as a pooling of interests.  RF 
Power Products will operate as a wholly-owned subsidiary of Advanced Energy. RF

Products designs and manufactures radio frequency (RF) power systems, matching 
networks and peripheral products primarily for original equipment providers in 
semiconductor, commercial coating, flat panel display and analytical 
instrumentation markets.

Douglas S. Schatz, Advanced Energy's Chairman and Chief Executive Officer, said,
"As an established provider of RF power systems, RF Power Products will boost 
Advanced Energy's presence in the RF market and bring us additional 
technological resources. Combined with our RF technology, this acquisition 
enables Advanced Energy to provide our global customers with a complete suite of
RF power solutions, while expanding the technology base and service capabilities
of both companies."

"This exciting union will offer significant benefits to customers by providing 
broad power and frequency ranges not currently available from any one source, 
including a vast array of RF power products. The combined technology is the best
available in the market today.  With this acquisition, our combined companies 
will be able to more broadly apply product development resources toward meeting 
future customer needs," Schatz said.

"Having been in business for many years, RF Power Products has established 
strong relationships with a number of global leaders including Applied 
Materials, Lam Research and Veeco. These relationships will further strengthen 
Advanced Energy's own ties with some of these same customers, as well as allow 
us to enter new customer relationships and industries, including food processing
and instrumentation, which are new market sectors for us. We are excited by the 
tremendous people that RF Power Products has to complement the extremely 
talented employees of Advanced Energy," he said.

Schatz further stated that the acquisition of RF Power Products gives Advanced 
Energy access to a more available labor base than that available in the Fort 
Collins, Colorado area at the engineering and human resources levels.  "RF 
Power Products' location in New Jersey has one of the greatest concentrations of
RF engineers in the country because of its proximity to the defense industry and
major research companies. The ability to tap this labor base solves an issue we 
have experienced in the past due to our location," he said.

"We are also delighted that Messrs. Zafiropoulo and Starek, currently directors 
of RF Power Products, will join the board of Advanced Energy at the closing 
date," he added.

Through the acquisition of RF Power Products, Advanced Energy accelerates its 
global expansion in the RF market. In addition to its manufacturing 
headquarters, RF Power Products has sales and service offices in Santa Clara, 
California, Austin, Texas and the

United Kingdom, and technical representatives and distributors in Korea, Taiwan 
and Japan.

Dr. Joseph Stach, RF Power Products' President and Chief Executive Officer, 
stated, "RF Power Products' strengths lie in our RF technology and people base 
that include some of the country's leading RF engineers. These strengths 
together with Advanced Energy's technology, people and leading market position, 
will expand both companies presence in the power systems market. Together, we 
will be able to offer customers a complete line of power systems solutions, 
including the latest developments in RF technology."

The acquisition is expected to be completed in the third quarter of 1998.  
Closing of the acquisition is subject to numerous conditions and there is no 
assurance that it will be completed.
