Dear General Microwave Shareholder:
 
You are cordially invited to attend a Special Meeting of the Shareholders of
General Microwave Corporation, to be held at the headquarters of General
Microwave, 5500 New Horizons Boulevard, Amityville, NY 11701 on January 6, 1999
at 10:00 a.m. local time.
 
At this meeting, you will be asked to approve and adopt an Agreement and Plan of
Merger, as amended, among General Microwave, certain shareholders of General
Microwave, Herley Industries, Inc. and GMC Acquisition Corporation, a
wholly-owned subsidiary of Herley.
 
In the merger, for each share of General Microwave common stock you own, you
will receive $18.00 in cash and a Warrant to purchase one share of Herley common
stock at a price of $14.40 per share if the Warrant is exercised on or before
January 11, 1999, and $15.60 per share if the Warrant is exercised after January
11, 1999. The $18.00 per share price, without taking into account the value of
the Warrant, represents a 69% premium over the $10.625 per share closing market
price of General Microwave common stock on August 21, 1998, which was the last
full trading day before the announcement of the proposed merger between Herley
and General Microwave. After the merger, General Microwave will be a subsidiary
of Herley.
 
The Board of Directors of General Microwave has unanimously approved the merger
agreement with Herley. The entire Board of Directors believes that the proposed
merger is in the best interests of General Microwave's shareholders and,
together with three other General Microwave shareholders, has granted proxies to
Herley to vote their shares (approximately 30% in the aggregate) in favor of the
merger agreement. The Board of Directors unanimously recommends that you vote in
favor of the merger agreement.
 
The attached notice of meeting and proxy statement explain the proposed merger
and provide specific information concerning the Special Meeting. Please read
these materials carefully.
 
Whether or not you plan to attend the Special Meeting, I urge you to complete,
sign and promptly return the enclosed proxy card to ensure that your shares will
be voted at the meeting. The merger is an important decision for General
Microwave and its shareholders. The merger cannot be completed unless
shareholders holding two-thirds of the outstanding shares of General Microwave
common stock approve the merger agreement.
 
On behalf of the Board of Directors, I thank you for your support and urge you
to vote FOR adoption of the merger agreement.
 
                                          Sincerely,
 
                                          Sherman A. Rinkel

    implement the merger. If the Agreement and Plan of Merger, as amended, is
    adopted by the shareholders and the other conditions to the merger are
    satisfied or waived, (x) GMC Acquisition will be merged with and into GMC
    and (y) each share of GMC common stock will be converted into the right to

2.  To transact such other matters as may properly come before the meeting or
    any adjournment or postponement of the meeting.
 
Any shareholder who does not wish to accept the merger consideration of $18.00
per share and a Herley common stock warrant and who properly dissents from the
proposed merger and complies with the requirements of Sections 623 and 910 of
the New York Business Corporation Law will have the right to receive payment in

             PROXY STATEMENT FOR SPECIAL MEETING OF SHAREHOLDERS OF
                         GENERAL MICROWAVE CORPORATION
 
                     PROSPECTUS OF HERLEY INDUSTRIES, INC.
 
The Boards of Directors of Herley Industries, Inc. and General Microwave
Corporation have approved a merger agreement that would result in GMC becoming a
wholly-owned subsidiary of Herley.
 
If the merger is completed, GMC shareholders will receive, for each GMC share,
$18.00 in cash and one Warrant to purchase one share of Herley common stock at a
purchase price of $14.40 if exercised on or before January 11, 1999 and $15.60
if exercised after January 11, 1999. Each outstanding option to purchase GMC
shares under the GMC 1990 Stock Option Plan and the GMC 1997 Non-Employee
Director Stock Option Plan will be cancelled in exchange for a Warrant to
purchase one share of Herley common stock and cash equal to $18.00 minus the per
share exercise price of the option, minus any amounts required for Federal and
State withholding taxes. Herley stockholders will continue to own their existing
shares of Herley stock after the merger.
 
The shares of Herley common stock that will be owned by GMC shareholders,
assuming the exercise of the Warrants, will represent approximately 15% of the
outstanding Herley common stock after the merger. The shares of Herley common
stock owned by Herley stockholders, assuming the exercise of the Warrants, will
represent approximately 85% of the outstanding Herley common stock after the
merger.
 
Shareholders of GMC are being asked, at the GMC special meeting of shareholders
being held on January 6, 1999, to approve the merger agreement, as amended, and
the merger. The merger cannot be completed unless the shareholders of GMC
approve it.
 
This document gives you detailed information about the proposed merger. Herley

Q:  WHY IS THE BOARD OF DIRECTORS RECOMMENDING THAT I VOTE FOR THE MERGER
AGREEMENT?
 
A:  In the opinion of your board, the merger is in the best interests of GMC and
its shareholders and the merger consideration of $18.00 per share plus a Herley
common stock warrant is fair from a financial point of view to GMC's
shareholders. For the merger to occur, shareholders holding two-thirds of the
outstanding shares of GMC common stock must approve the merger. To review the

instruct your broker to vote your shares.
 
Q:  MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?
 
A:  Yes. Just send in a later dated, signed proxy card before the Special
Meeting or attend the Special Meeting and vote.

A:  We are working toward completing the merger as quickly as possible. We
expect to complete the merger by January 8, 1999.

income tax purposes. You are urged to consult your own tax advisor to determine
your particular tax consequences.

<PAGE>   12
 
three operating divisions in three locations with strong inter-divisional ties.
GMC's largest division, its microwave division, is located in Amityville, New
York. A substantial portion of GMC's microwave products is sold to manufacturers
and users of microwave systems and equipment for applications in the defense
electronics industry. GMC also sells these components and equipment for use in
the industrial sector as well as in commercial telecommunications industries.
 
The General Microwave Israel Corporation and General Microwave Israel (1987)
Ltd., subsidiaries in Jerusalem, Israel, conduct research and development and
manufacturing operations largely devoted to the production of microwave
oscillators. The General Microcircuits Corporation subsidiary in Billerica,
Massachusetts, engages in the design, manufacture and sale of hybrid
microcircuits largely intended for military applications.
 
GMC'S REASONS FOR THE MERGER
 
In reaching its decision to approve the Agreement and to recommend that GMC's
shareholders vote to adopt the Agreement, the GMC Board of Directors considered
a number of factors, including GMC's financial condition, strategic alternatives
to the proposed merger, the relationship between the value of the merger
consideration and the recent trading prices of GMC common stock, the strategic
fit between GMC and Herley, and the terms and conditions of the Agreement. The
Agreement was later amended to provide that GMC, rather than Acquisition, would
be the surviving corporation in the Merger. Any references to the Agreement are
to the Agreement as amended.
 
THE GMC SPECIAL MEETING
 
TIME, DATE, PLACE AND PURPOSE
 
A Special Meeting of Shareholders of GMC will be held at GMC's offices at 5500
New Horizons Boulevard, Amityville, New York on Wednesday, January 6, 1999 at
10:00 a.m., local time. The purpose of the GMC Meeting is to approve and adopt
the Agreement and to transact any other business as may properly come before the
GMC Meeting or any postponements or adjournments thereof. See "General Microwave

"-- Purpose."
 
RECORD DATE AND VOTE REQUIRED
 
Only GMC shareholders of record at the close of business on November 17, 1998
are entitled to notice of and to vote at the GMC Meeting. Pursuant to New York
Business Corporation Law, the affirmative vote of the holders of two-thirds of
the GMC common stock outstanding as of the GMC Record Date is required to

As of November 17, 1998, there were 154 shareholders of record of GMC common
stock and 1,214,275 shares of GMC common stock outstanding, each of which will
be entitled to cast one vote per share on each matter to be acted upon at the
GMC Meeting.
 
HERLEY IRREVOCABLE PROXIES AND STOCK OWNERSHIP
 
Each of the nine members of the Board of Directors of GMC, two officers of GMC,
and Mr. Frederick Zissu, a large shareholder and former Chairman of GMC, have
granted irrevocable proxies to Herley to vote their shares (approximately 30% in
the aggregate of the outstanding GMC common stock) in favor of the Agreement. In
addition, as of
                                        3
<PAGE>   13
 
November 17, 1998, Herley owned an additional approximately 30% of the
outstanding GMC common stock.
 
RECOMMENDATION OF GMC BOARD OF DIRECTORS
 
GMC's Board of Directors has unanimously approved the Agreement and the
transactions contemplated thereby and has determined that the Merger is fair and
in the best interests of GMC and its shareholders. After careful consideration,
the GMC Board unanimously recommends a vote in favor of approval and adoption of
the Agreement. GMC Shareholders should read this Proxy Statement/Prospectus
carefully prior to voting. See "The Merger -- GMC's Reasons for the Merger,"
"-- Herley's Reasons for the Merger," and "General Microwave Corporation Special
Meeting -- Recommendation of GMC Board of Directors."
 
THE MERGER
 
TERMS OF THE MERGER
 
The Merger will be effective at the time the Certificate of Merger is filed with
the Secretary of State of the State of New York or any later time which is
agreed to in writing by Herley, GMC and Acquisition and specified in the
Certificate of Merger. At such Effective Time, Acquisition will merge with and
into GMC and GMC will become a wholly-owned subsidiary of Herley. Herley
currently intends to combine its operations with GMC's operations as soon as
practicable following the closing of the Merger. In the Merger, each outstanding
share of GMC common stock will be converted into the right to receive $18.00 in
cash and a Warrant to purchase one share of Herley common stock at a price of
$14.40 per share, if exercised on or before January 11, 1999 and $15.60 per
share if exercised after January 11, 1999. See "Description of Herley Capital
Stock -- Description of Warrants." Shares of GMC common stock owned by holders
who have exercised appraisal rights under New York law and shares held in the
treasury of GMC or owned by Acquisition, Herley or any wholly-owned subsidiary
of Herley or GMC will not be converted in the Merger. Each outstanding option or
right to purchase GMC common stock under the GMC Stock Option Plans will be
cancelled in exchange for the right to receive cash equal to $18.00 minus the
per share exercise price of such option and minus any amounts required for
Federal and State withholding taxes, and a Warrant to purchase one share of
Herley common stock. See "Certain Provisions of the Merger Agreement --
Conversion of Shares and Options."
 
EFFECTIVE TIME OF THE MERGER
 
The Merger is expected to close and the Effective Time is expected to be on or
about January 8, 1999, assuming all of the conditions to the Merger are met or
waived prior to that date. See "Certain Provisions of the Merger
Agreement -- Effective Time."
 
EXCHANGE OF GMC STOCK CERTIFICATES
 
Promptly after the Effective Time, American Stock Transfer and Trust Company, as
Herley's paying agent, will deliver to each GMC shareholder of record a letter
of transmittal with instructions regarding how to surrender GMC share
certificates. YOU SHOULD NOT SURRENDER YOUR GMC COMMON STOCK UNTIL YOU RECEIVE
THE LETTER OF TRANSMITTAL FROM THE PAYING AGENT. Each outstanding option or
right to purchase GMC common stock under the GMC Stock Option Plans will be
converted into the right to receive for each share of GMC stock
                                        4
<PAGE>   14
 
subject to the option an amount in cash equal to $18.00 minus the per share
exercise price and a Warrant to purchase one share of Herley common stock.
Holders of options to purchase GMC stock will also receive instructions
regarding how to surrender their options. YOU MUST SURRENDER OPTION AGREEMENTS
TO THE SECRETARY OF HERLEY OR OTHERWISE CONFIRM TO HERLEY IN WRITING WHAT YOUR
OPTION HOLDINGS ARE. See "Certain Provisions of the Merger
Agreement -- Conversion of Shares and Options."
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
Based on the number of shares of GMC common stock and the number of shares of
Herley common stock outstanding on November 17, 1998, assuming the exercise of
the Warrants and that no GMC shareholders exercise appraisal rights (i) the
shares of Herley common stock that will be owned by GMC shareholders will
represent approximately 15% of the outstanding Herley common stock after the
merger and (ii) the shares of Herley common stock owned by Herley stockholders
will represent approximately 85% of the outstanding Herley common stock after
the merger. See "The Merger -- Stock Ownership Following the Merger."
 
NO SOLICITATION BY GMC
 
Until the earlier of the Effective Time of the Merger or termination of the
Agreement pursuant to its terms, GMC and the GMC shareholders who are parties to
the Agreement have agreed not to, and GMC has agreed to instruct its directors,
officers, affiliates and advisors not to, directly or indirectly, solicit,
initiate or encourage inquiries or proposals with respect to, furnish any
information relating to, or participate in, continue or enter into any
negotiations or discussions concerning, any business combination with or the
purchase of all or a portion of the assets of, or any equity interest in GMC or
its subsidiaries. GMC and those GMC shareholders have also agreed to immediately
notify Acquisition if any person inquires or makes a proposal regarding any
acquisition and to as promptly as practicable notify Acquisition of the
significant terms and conditions of any such acquisition proposal. See "Certain
Provisions of the Merger Agreement -- Conduct of GMC's Business Prior to The
Merger" and " -- Termination."

See "Certain Provisions of the Merger Agreement -- Conditions to the Merger."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
In considering the recommendation of the GMC Board with respect to the
Agreement, holders of GMC common stock should be aware that certain members of
the GMC Board and certain executive officers of GMC have certain interests in
the Merger that are in addition to the interests of holders of GMC common stock
generally. See "The Merger -- Interests of Certain Persons."
 
APPRAISAL RIGHTS
 
Holders of GMC common stock will be entitled to appraisal rights under the New
York Business Corporation Law in connection with the Merger. A holder of GMC
common stock who desires to pursue appraisal rights must (i) file a written
objection to the Agreement with GMC before the taking of the shareholders' vote
on the Agreement, (ii) refrain from voting in favor of the Agreement, and (iii)
make written demand from the surviving corporation for payment for the
shareholder's shares, all in accordance with the New York Business Corporation
Law. Such appraisal rights are conditioned upon not voting for the Agreement.
See "The Merger -- Appraisal Rights."
 
ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW AND HERLEY'S CHARTER DOCUMENTS
 
Certain provisions of Delaware law and Herley's Certificate of Incorporation and
By-laws could make it more difficult for a third party to acquire control of
Herley without the approval of its Board of Directors, even if the change in
control could be beneficial to the interests of Herley's stockholders. Herley is
and will be subject to the provisions of Section 203 of the Delaware General
Corporation Law. Section 203 restricts a corporation from entering into certain
"business combinations" with an "interested person" for a period of three years.
An interested person is generally defined to mean a person or entity that has
acquired in excess of 15% of a company's voting stock. Herley's Board of
Directors will continue to be classified into three classes, so a person who
wishes to propose an alternative slate of nominees to Herley's Board of
Directors can propose nominees for only one-third of the Board per year.
Herley's Certificate of Incorporation will continue to require that certain
transactions, including mergers and sales or transfers of all or substantially
all of the assets to "interested persons"as defined in Section 203 of the
Delaware General Corporation Law, be approved by holders of 80% of the stock.
See "Comparison of Capital Stock."

FAIRNESS OPINION
 
Franco, Lewis & Company, Inc. has delivered to the GMC Board its written
opinion, dated November 12, 1998, to the effect that, as of November 12, 1998,
the consideration to be received by the holders of GMC common stock in the
Merger was fair from a financial point of view. The full text of the opinion of
Franco, Lewis & Company, Inc., which sets forth assumptions made and matters
considered, is attached hereto as Annex C to this Proxy Statement/Prospectus,
and is incorporated herein by reference. HOLDERS OF GMC COMMON STOCK ARE URGED
TO, AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY. See "The Merger -- Fairness
Opinion of Franco, Lewis & Company, Inc." and Annex C attached hereto.
 
INCOME TAX TREATMENT
 
Assuming that a holder of GMC common stock holds his or her shares as a capital
asset, the holder will recognize capital gain or loss equal to the difference
between (i) the cash and the fair market value of the Warrant received and (ii)
the holder's basis in the GMC common stock given up in the exchange. Under the
federal income tax backup withholding rules, the Paying Agent will generally be
required to withhold 31% of all payments to a payee, unless the payee provides a
tax identification number (social security number, in the case of an individual,
or employer identification number in the case of other GMC shareholders) and
certifies that the tax identification number is correct. Any amounts withheld
will be allowed as a credit against the holder's Federal income tax liability.
 
ALL GMC SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS. See "The
Merger -- Certain U. S. Federal Income Tax Consequences of the Merger."
 
REGULATORY MATTERS
 
Herley and GMC are not aware of any material governmental or regulatory
approvals which are required for consummation of the Merger, other than
compliance with the federal securities laws and applicable state securities and
"blue sky" laws. See "The Merger -- Governmental and Regulatory Approvals."
 
ACCOUNTING TREATMENT
 
It is anticipated that the Merger will be accounted for as a "purchase"
transaction. Under the purchase method of accounting, the value of the assets
and liabilities of GMC will be recorded at their estimated fair market value at
the Effective Time of the Merger and goodwill will be recorded to the extent
that the purchase price exceeds the fair market value of the net assets
acquired. The consolidated results of operations of GMC will be included in the
consolidated results of operations of Herley from the Effective Time of the
Merger and not for the entire fiscal year ending August 1, 1999. See "The
Merger -- Accounting Treatment."
 
RISK FACTORS
 
For a discussion of the risks of an investment in Herley common stock, see "Risk
Factors."

       SELECTED HISTORICAL AND SELECTED PRO FORMA COMBINED FINANCIAL DATA
 
The following selected historical financial information of Herley and GMC,
except for the GMC data as of and for the six months ended August 30, 1997 and
August 29, 1998, has been derived from their respective historical audited
consolidated financial statements, and should be read in conjunction with such
consolidated financial statements and the notes thereto, included elsewhere in
this Proxy Statement/ Prospectus. The statement of operations data of GMC
presented below for the six month periods ended August 30, 1997 and August 29,
1998 and the balance sheet data as of August 30, 1997 and August 29, 1998 were
derived from unaudited consolidated financial statements of GMC included
elsewhere in this Proxy Statement/Prospectus. Such unaudited consolidated
financial statements, in the opinion of GMC's management, contain all
adjustments, consisting of normal recurring accruals, necessary for a fair
presentation of the consolidated financial position and results of operations
for these periods. The selected pro forma financial information is derived from
the unaudited pro forma combined condensed financial statements, which give
effect to the Merger as a purchase, and should be read in conjunction with such
unaudited pro forma combined condensed statements and the notes thereto included
in this Proxy Statement/Prospectus. For purposes of the pro forma operating
data, Herley's consolidated financial statements for the 52 weeks ended August
2, 1998 have been combined with the GMC financial statements for the
twelve-month period ended August 29, 1998. No cash dividends have been declared
or paid on Herley common stock for the past five years. GMC paid a special cash
dividend of $0.25 per share on February 9, 1994. The pro forma information is
presented for illustrative purposes only and is not necessarily indicative of
the operating results or financial position that would have occurred if the
Merger had been consummated at the beginning of the periods indicated, nor is it
necessarily indicative of future operating results or financial position.

                              GENERAL INFORMATION
 
This Proxy Statement/Prospectus is furnished by GMC in connection with the
solicitation of proxies to be used at the GMC Meeting. This Proxy
Statement/Prospectus is also furnished by Herley to GMC shareholders in
connection with the issuance of Warrants to purchase shares of Herley common
stock in connection with the Merger described herein.
 
Herley has provided the information concerning Herley Acquisition and the pro
forma financial information regarding the Combined Company, and GMC has provided
the information concerning GMC. As used herein, the term "Combined Company"
means Herley and GMC and their respective subsidiaries as a consolidated entity
following the Merger, and references to the products, business, results of
operations or financial condition of the Combined Company should be considered
to refer to Herley and GMC, unless the context otherwise requires.

                                  RISK FACTORS
 
IN EVALUATING THE PROPOSALS TO BE VOTED ON THE GMC MEETING AND THE ACQUISITION
OF THE SECURITIES OFFERED BY THIS PROXY STATEMENT/PROSPECTUS YOU SHOULD CONSIDER
CAREFULLY THE FOLLOWING FACTORS.
 
RISKS RELATING TO INTEGRATION OF OPERATIONS
 
Herley has entered into the Agreement because it expects that the proposed
Merger will result in long-term strategic benefits. Achieving these benefits
will depend in part on whether Herley and GMC's operations can be integrated
efficiently and effectively. There can be no assurance that this will occur. The
combination of the companies will require, among other things, integration of
the companies' respective product offerings and coordination of their sales,
marketing and research and development efforts.
 
The successful expansion of Herley's business will require communication and
cooperation in product development and marketing among the senior executives and
key technical personnel of Herley and GMC. Given the inherent difficulties
involved in completing a major business combination there can be no assurance
that:
 
     - cooperation among Herley and GMC's senior executives and key technical
       personnel will occur;
 
     - Herley will retain its and GMC's key technical and management personnel;
 
     - the business combination will not result in disruptions in the Combined
       Company's business;
 
     - the integration of the businesses of Herley and GMC will be successful;
       or
 
     - the Combined Company will realize any of the anticipated benefits of the
       Merger.
 
The integration of operations following the Merger will require the dedication
of management resources, which may distract attention from day-to-day
operations. The inability of management to successfully integrate the operations
of the companies could have a material adverse effect upon the business,
operating results and financial condition of the Combined Company.
 
Herley also believes that the Combined Company will benefit from the combination
of Herley and GMC's marketing efforts, but there can be no assurance that the
Combined Company will be able to take full advantage of such combination or that
channel conflicts will not develop due to the attempt to integrate Herley and
GMC's separate distribution channels.
 
NO ADJUSTMENTS TO CONSIDERATION
 
Under the terms of the Agreement, each share of GMC common stock issued and
outstanding at the Effective Time of the Merger will be converted into the right
to $18.00 in cash and a Warrant to purchase one share of Herley common stock.
The Agreement does not provide for adjustment of the consideration based on
fluctuations in the price of Herley common stock or GMC common stock.
Accordingly, some of the value of the consideration to be received by
shareholders of GMC upon the Merger will depend on the market price of the
Herley common stock at the Effective Time . There can be no assurance that the
market price of the Herley common stock after the Effective Time will not be
lower than the exercise price of the Warrant.
 
                                       14
<PAGE>   24
 
EFFECTS OF MERGER ON CUSTOMERS
 
There can be no assurance that the present and potential customers of GMC and
Herley will continue their current buying patterns without regard to the
proposed Merger. Any significant delay or reduction in orders could have an
adverse effect on the near-term business and results of operations of the
Combined Company.
 
RISKS ASSOCIATED WITH EXPANSION INTO NEW MARKETS
 
The Combined Company can be expected to introduce new products and expand its
product offerings in the existing markets of Herley and GMC. Broad market
acceptance of the Combined Company's new products is critical to the Combined
Company's future success. Herley believes that factors affecting the ability of
the Combined Company's products to achieve broad market acceptance include:
 
     - product performance,
 
     - price,
 
     - adaptation to rapid technological change, and
 
     - competitive product offerings.
 
There can be no assurance that the Combined Company will be able to respond
promptly and effectively to the challenges of technological change and its
competitors' innovations, or that the Combined Company will be able to achieve
the necessary market acceptance, or compete effectively, in its product markets.
 
FLUCTUATIONS IN QUARTERLY RESULTS; FUTURE OPERATING RESULTS UNCERTAIN
 
Herley's and GMC's quarterly operating results have in the past, and the
Combined Company's results may in the future, fluctuate significantly depending
on factors such as:
 
     - demand for its products,
 
     - the size and timing of orders,
 
     - the number, timing and significance of new product announcements by it
       and its competitors,
 
     - its ability to develop, introduce and market new and enhanced versions on
       a timely basis,
 
     - the level of product and price competition,
 
     - changes in operating expenses,
 
     - changes in average selling prices and product mix,
 
     - product returns,
 
     - changes in technology, and
 
     - general economic factors.
 
As a result, because product revenues in any quarter may be substantially
dependent on orders booked and shipped in that quarter, revenues for any future
quarter may not be predictable with any significant degree of accuracy. If
revenue levels are below expectations, operating results are likely to be
adversely affected and may be below the
 
                                       15
<PAGE>   25
 
expectations of public market analysts and investors. In such event, the price
of the Herley common stock would likely decrease.
 
TECHNOLOGICAL CHANGE
 
The flight instrumentation industry is characterized by technological change.
Herley's future success will depend upon its ability to continually enhance its
current products and systems and develop and introduce new products and systems
that keep pace with the increasingly sophisticated needs of its customers and
the technological advancements of its competitors. There can be no assurance
that Herley will be successful in developing and marketing product enhancements,
new products or totally new systems that will adequately meet the requirements
of the marketplace. As a result, Herley has expended substantial resources for
system and product development and intends to continue to expend such resources
in the future. The development of new or enhanced systems or products results in
expenditures and costs that Herley may not recover if the system or product is
unsuccessful. See "The Companies -- Business of Herley."
 
DEPENDENCE UPON KEY PERSONNEL
 
The success of Herley depends upon the efforts of its executive officers and
other key personnel, including Lee N. Blatt, Chairman of the Board and Chief
Executive Officer and Myron Levy, President, and in the event of an acquisition,
its ability to attract and retain other highly qualified management and
technical personnel. Although Herley has existing employment agreements with
Messrs. Blatt and Levy the loss of the services of Mr. Blatt and Mr. Levy could
have an adverse effect on the Combined Company's business and prospects. Herley
does not maintain key-man life insurance. There can be no assurance that Herley
will be successful in the event it needs to hire and retain additional key
personnel. See "Management."
 
INTERNATIONAL SALES; CURRENCY FLUCTUATIONS
 
International sales represented approximately 29% of Herley's total revenues for
the 52 weeks ended August 2, 1998 and the 53 weeks ended August 3, 1997.
International sales represented approximately 34% of GMC's total revenues for
the fiscal years ended February 28, 1998 and the six months ended August 29,
1998. Herley believes that continued profitability requires additional expansion
of sales in foreign markets. This expansion will continue to require significant
management attention and financial resources and could adversely affect the
Combined Company's operating margins. In order to increase international sales
in the future, the Combined Company may be required to establish additional
foreign operations, hire additional personnel and recruit additional
international resellers. To the extent that the Combined Company is unable to
expand international sales in a timely and cost-effective manner, its business,
operating results and financial condition could be materially adversely
affected. In addition, there can be no assurance that the Combined Company will
be able to maintain or increase international market demand for its products.
 
All of Herley's and GMC's international sales are currently denominated in U.S.
dollars. Consequently, Herley and GMC do not currently engage in any hedging
activities. To date, exposure to currency fluctuations has not been significant
but there can be no guarantee that future fluctuations in the currency exchange
rates will not have a material adverse effect on the Combined Company's
business, operating results and financial condition.
 
                                       16
<PAGE>   26
 
Additional risks inherent in the Combined Company's international business
activities include:
 
     - unexpected changes in regulatory requirements;
 
     - tariffs and other trade barriers;
 
     - costs of localizing products for foreign countries;
 
     - lack of acceptance of localized products in foreign countries;
 
     - longer accounts receivable payment cycles;
 
     - difficulties in collecting payment;
 
     - difficulties in managing international operations;
 
     - potentially adverse tax consequences, including repatriation of earnings;
 
     - reduced protection for intellectual property;
 
     - the burdens of complying with a wide variety of foreign laws; and
 
     - the effects of high local wage scales and other expenses.
 
There can be no assurance that such factors will not have a material adverse
effect on the Combined Company's future international sales and, consequently,
the Combined Company's business, operating results and financial condition.
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY; RISK OF THIRD PARTY CLAIMS FOR
INFRINGEMENT
 
Herley does not have any patents. GMC has 12 patents in the United States which
cover various products. The Combined Company will rely on a combination of
patent, copyright and trademark laws, trade secrets, confidentiality procedures
and contractual provisions to protect its proprietary rights. The laws of some
foreign countries do not protect proprietary rights as thoroughly as do the laws
of the United States. Policing unauthorized use of Herley's or GMC's products is
difficult, time-consuming and costly. However, the actions taken by the Combined
Company to establish and protect its proprietary rights may not be enough to
prevent imitation of its products or to prevent others from claiming violations
of their proprietary rights by the Combined Company. Any such claims, whether
with or without merit, could be time-consuming, result in costly litigation and
diversion of resources, cause product shipment delays or require the Combined
Company to enter into royalty or licensing agreements. Any such royalty or
licensing agreements may not be available on terms acceptable to the Combined
Company or at all. In the event of a successful claim of product infringement
against the Combined Company and the failure or inability of the Combined
Company to license the infringed or similar technology, the Combined Company's
business, operating results and financial condition could be materially
adversely affected.
 
POTENTIAL ANTI-TAKEOVER PROVISIONS
 
Certain provisions of Delaware law and the Combined Company's Certificate of
Incorporation and By-laws could make it more difficult for a third party to
acquire control of Herley, even if the change in control could be beneficial to
the interests of the stockholders. These provisions include:
 
     - Section 203 of the Delaware General Corporation Law, which prohibits
       certain business combinations with interested stockholders,
 
                                       17
<PAGE>   27
 
     - the classification of Herley's Board of Directors into three classes and
 
     - the requirement that stockholders owning at least 80% of the outstanding
       shares of Herley common stock approve certain transactions, including
       mergers and sales or transfers of all or substantially all of the assets
       of the Combined Company.
 
These provisions could limit the price that certain investors might be willing
to pay in the future for shares of Herley common stock and the Warrants. See
"Description of Herley Capital Stock."
 
YEAR 2000 RISK
 
The "Year 2000" problem relates to computer systems that have time and
date-sensitive programs that were designed to read years beginning with "19",
but may not properly recognize the year 2000. If a computer system or software
application used by Herley or a third party dealing with Herley fails because of
the inability of the system or application to properly read the year 2000 the
results could have a material adverse effect on Herley.
 
A substantial part of Herley's revenues are derived from firm fixed price
contracts with U.S. government agencies, prime contractors or subcontractors on
military or aerospace programs, and many foreign governments. If Herley is
unable to perform under these contracts due to a Year 2000 problem, the customer
could terminate the contract for default. While lost revenues from such an event
are a concern for Herley, the greater risks are the consequential damages for
which Herley could be liable for failure to perform under the contracts. Such
damages could have a material adverse impact on Herley's results of operations
and financial position. Herley has reviewed its computer and other systems to
attempt to ensure that they will be Year 2000 compliant. Herley has been advised
by the provider of its computer hardware that the hardware complies with Year
2000 requirements. Herley's financial, manufacturing, and other software
applications related to its hardware have been updated to comply with Year 2000.
Certain modules have been fully tested, with the remaining modules to be tested
by the end of fiscal 1999.
 
Herley is also reviewing its utility systems (heat, light, phones, liquid
nitrogen, etc.) for the impact of Year 2000, as well as determining the state of
readiness of its material suppliers. This process will be ongoing and Herley's
efforts with respect to specific problems identified, and future costs
associated with them, will depend in part upon its assessment of the risk that
any such problems may cause a disruption in manufacturing or other problem which
Herley believes would have a material adverse impact on its operations. However,
Herley cannot control the conduct of its suppliers. Therefore, there can be no
guarantee that Year 2000 problems originating with a supplier will not occur.
There can be no absolute assurance that third parties will convert their systems
in a timely manner. Herley believes that its actions will minimize these risks
and that any additional cost of Year 2000 compliance for its information and
production systems will not be material to its consolidated results of
operations and financial position.
 
ADDITIONAL ISSUANCES OF STOCK WITHOUT STOCKHOLDER APPROVAL
 
After this offering, Herley will have an aggregate of approximately 8,903,302
shares of common stock authorized but unissued and not reserved for specific
purposes. All of such shares may be issued without any action or approval by the
Combined Company's stockholders. Any shares issued would further dilute the
percentage ownership of the Company held by the investors in this offering.
Unissued but reserved shares of Herley common stock include shares of common
stock reserved for issuance in connection with the exercise of (i) the Warrants,
(ii) the stock options issued under Herley's stock option
                                       18
<PAGE>   28
 
plans, (iii) currently outstanding warrants, including the warrants held by
officers and directors.
 
The market price of the Herley common stock could drop as a result of sales of a
large number of shares in the market, or the perception that such sales could
occur. These factors could also make it more difficult for the Combined Company
to raise funds through future offerings of Herley common stock during the terms
of these stock options and warrants because of the potential dilution and
because the holders thereof might be expected to convert or exercise them if the
market price of the Herley common stock exceeds their conversion or exercise
price. See "Description of Herley Capital Stock."

TRANSACTIONS. THE FOLLOWING IS NOT, HOWEVER, A COMPLETE STATEMENT OF ALL
PROVISIONS OF THE AGREEMENT AND RELATED AGREEMENTS. DETAILED TERMS OF AND
CONDITIONS TO THE MERGER AND CERTAIN RELATED TRANSACTIONS ARE CONTAINED IN THE
AGREEMENT, A COPY OF WHICH IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS

ALSO MADE TO THE OTHER ANNEXES HERETO. STATEMENTS MADE IN THIS PROXY
STATEMENT/PROSPECTUS WITH RESPECT TO THE TERMS OF THE MERGER AND SUCH RELATED
TRANSACTIONS ARE QUALIFIED IN THEIR RESPECTIVE ENTIRETIES BY REFERENCE TO THE
MORE DETAILED INFORMATION SET FORTH IN THE AGREEMENT AND THE OTHER ANNEXES
HERETO. THIS SECTION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN
THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF A VARIETY OF FACTORS, INCLUDING
THOSE SET FORTH IN "RISK FACTORS" AND ELSEWHERE HEREIN.
 
BACKGROUND OF THE MERGER
 
The terms of the Agreement are the result of arm's-length negotiations between
representatives and legal advisors of Herley and GMC. The following is a brief
discussion of the background of those negotiations.
 
In early July 1998, Mr. Lee N. Blatt, Chairman and Chief Executive Officer of
Herley, called Mr. Sherman Rinkel, Chairman of GMC, to indicate that Herley was
interested in pursuing an alliance with GMC. Following that initial contact
Messrs. Blatt and Rinkel had preliminary discussions regarding a possible
acquisition of GMC by Herley.
 
On July 17, 1998, Messrs. Blatt and Rinkel met to discuss the general terms of a
merger with no specific agreement resulting. At the meeting, Mr. Blatt expressed
an interest in acquiring GMC at a purchase price of $16 per share. Mr. Rinkel
informed Mr. Blatt that the proposed purchase price was insufficient. Messrs.
Blatt and Rinkel agreed to have further discussions regarding a possible
transaction between Herley and GMC and to inform their respective Boards of
Directors regarding the status of such discussions.
 
From July 17 to July 31, 1998, Mr. Blatt, Mr. Rinkel and, on one occasion, Mr.
Michael Magidson, a director of GMC, held various meetings in person and by
telephone to further discuss a possible transaction between GMC and Herley and
Mr. Rinkel discussed the proposed acquisition with members of the Board of
Directors and GMC's legal counsel, Mr. Michael I. Stolzar, who is also a
director. By July 31, 1998, Messrs. Blatt and Rinkel had reached a preliminary
agreement as to a purchase price of $18 per share in cash and a Warrant to
purchase one share of Herley common stock, subject to the execution of a
definitive agreement.
 
On August 3, 1998, Mr. Stolzar and Herley's legal counsel, Mr. David H.
Lieberman, a director of Herley, began discussions related to the terms and
conditions of the Agreement. On August 11, 1998, Mr. Lieberman delivered a draft
of the Agreement to GMC and Mr. Stolzar, which contained, among other things, a
requirement that the directors of GMC and certain other GMC shareholders execute
irrevocable proxies in favor of the Merger. Over the next ten days, Messrs.
Stolzar and Lieberman held several meetings by telephone in which various terms
of the Agreement, the proxies and the Warrant were negotiated. During the same
period of time, Mr. Rinkel continued to discuss the proposed acquisition with
members of the Board of Directors of GMC.
 
Concurrently with his negotiations with Herley, Mr. Rinkel contacted other third
parties involved in the electronics equipment and defense contracting industries
to determine
 
                                       22
<PAGE>   32
 
whether any of such parties were interested in a strategic alliance with or
acquisition of GMC. In response to his informal inquiries, Mr. Rinkel did not
receive any indications of interest from such third parties.
 
On August 21, 1998, at a special meeting, the GMC Board of Directors met to
review the proposed merger transaction. Mr. Rinkel and Mr. Stolzar reported on
their negotiations with Mr. Blatt and Herley's legal advisors. Mr. Rinkel
reviewed with the GMC Board his contacts with other third parties in the
electronics equipment and defense contracting industries regarding a possible
transaction. Following such discussions, the GMC Board of Directors approved the
terms of the proposed transaction with Herley and the Agreement. Following the
conclusion of GMC's special meeting on the evening of August 21, 1998, the
Agreement was executed and delivered by the parties. On August 24, 1998, Herley
and GMC issued a joint press release announcing the execution of the Agreement.
 
On November 5, 1998, Nancy D. Lieberman, one of Herley's legal counsel,
delivered to Mr. Stolzar a proposed Amendment No. 1 to Agreement and Plan of
Merger. The amendment contained, among other things, a revision that made GMC
the surviving corporation of the merger with Acquisition. On the following day,
Mr. Stolzar and Ms. Lieberman met by telephone to discuss the proposed
amendment. On November 12, 1998, at a special meeting, the GMC Board of
Directors met by telephone to review and approve the proposed amendment. At that
meeting, the GMC Board also considered the fairness opinion provided by Franco,
Lewis & Company, Inc. and called the Special Meeting of Shareholders of GMC to
consider approval and adoption of the Merger.
 
GMC'S REASONS FOR THE MERGER
 
The GMC Board has approved unanimously the Agreement, has determined unanimously
that the Merger is fair and advisable and in the best interests of GMC and its
shareholders and recommends unanimously that holders of GMC common stock vote
FOR approval of the Agreement.
 
In reaching its decision to approve the Agreement and to recommend that GMC's
shareholders vote to approve and adopt the Agreement, the GMC Board considered a
number of factors, including the following:
 
(i)   Information with respect to the financial condition, results of operations
      and business of GMC, on both a historical and a prospective basis, and the
      influence of current industry, economic and market conditions;
 
(ii)  Strategic alternatives (including continuing the GMC business in its
      present configuration on a stand-alone basis without significant changes),
      none of which the GMC Board believed to be as favorable to the holders of
      the shares of GMC common stock as the Merger;
 
(iii) The relationship of the value of the consideration offered to the recent
      trading prices of GMC common stock and the fact that the cash portion
      alone of the merger consideration represented a 69% premium over the
      closing price of GMC common stock on August 20, 1998 (the last full
      trading day prior to the approval of the Agreement by the GMC Board);
 
(iv)  The good strategic fit between the two companies in view of their
      respective product lines and markets that are expected to produce a
      favorable impact on the long-term value of Herley as well as enhance the
      competitive position of the combined entity;
 
                                       23
<PAGE>   33
 
(v)   The opportunity for all GMC shareholders to maintain an ownership stake in
      the combined entity and realize the potential long-term benefits of the
      Merger; and
 
(vi)  The terms and conditions of the Agreement, including the restrictions
      against GMC discussions with other potentially interested companies and
      the fact that either party could terminate the Agreement if the Merger is
      not consummated by January 8, 1999.
 
The GMC Board also considered certain potential risks relating to the Merger,
including but not limited to the risk that the Merger would not be consummated,
with resulting distraction in the interim to GMC's normal business operations.
The GMC Board believed, however, that these risks were outweighed by the
potential benefits to be realized from the Merger.
 
Based on this analysis, the GMC Board unanimously determined that the Merger is
fair to, and in the best interests of, GMC's shareholders. The foregoing
discussion of the information and factors considered by the GMC Board is not
intended to be exhaustive, and such information and factors were considered
collectively by the GMC Board in connection with its review of the Agreement and
the transactions contemplated thereby. In view of the variety of factors
considered in connection with its evaluation of the Merger, the GMC Board did
not find it practicable to, and did not, quantify or otherwise assign relative
weights to the specific factors considered in reaching its determination. In
addition, individual members of the GMC Board may have given different weights
to different factors.
 
THE GMC BOARD RECOMMENDS THAT GMC SHAREHOLDERS VOTE FOR THE APPROVAL AND
ADOPTION OF THE MERGER AND THE AGREEMENT.
 
HERLEY'S REASONS FOR THE MERGER
 
The Board of Directors of Herley believes that the Combined Company will have
the potential to realize long-term improved operating and financial results and
a stronger competitive position. Herley believes that there is a strategic fit
among the two companies' businesses. Herley also believes that the Merger will
provide greater opportunities to develop business relationships, license
technology, and engage in other strategic combinations and transactions
involving their respective products and technologies than would be the case if
the companies otherwise independently engaged in these activities.
 
OPINION OF FRANCO, LEWIS & COMPANY, INC.
 
GMC engaged Franco, Lewis & Company, Inc.("FLCI") to render an opinion as to the
fairness from a financial point of view to the holders of the outstanding shares
of GMC common stock of the consideration to be received by such holders in the
Merger. FLCI was selected by the GMC Board based on FLCI's qualifications and
expertise, as well as FLCI's historic investment banking relationship and
familiarity with GMC. FLCI rendered its written opinion on November 12, 1998 to
the GMC Board that, as of such date, the consideration to be received by the
holders of the common stock in the Merger is fair to such holders from a
financial point of view. No limitations were placed on FLCI by the GMC Board
with respect to the investigation made or the procedures followed in preparing
and rendering its opinion. However, for purposes of this opinion and with the
approval of the Board of Directors of GMC, FLCI assumed that the warrants to be
received in the Merger by holders of GMC common stock had no value.
 
                                       24
<PAGE>   34
 
THE FULL TEXT OF THE OPINION OF FLCI IS ATTACHED HERETO AS ANNEX C. GMC
SHAREHOLDERS ARE URGED TO READ THE OPINION IN ITS ENTIRETY FOR THE ASSUMPTIONS
MADE, PROCEDURES FOLLOWED, OTHER MATTERS CONSIDERED AND LIMITS OF THE REVIEW BY
FLCI. THE SUMMARY OF THE OPINION OF FLCI SET FORTH IN THIS PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCES TO THE FULL TEXT
OF SUCH OPINION. FLCI'S OPINION WAS PREPARED FOR THE GMC BOARD OF DIRECTORS AND
IS DIRECTED ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE
CONSIDERATION TO BE RECEIVED BY HOLDERS OF SHARES OF GMC COMMON STOCK PURSUANT
TO THE AGREEMENT AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY GMC SHAREHOLDER
AS TO HOW TO VOTE AT THE GMC MEETING.
 
In its review of the Merger, and in arriving at its opinion, FLCI, among other
things: (i) reviewed the publicly available consolidated financial statements of
GMC for recent years and interim periods to date and certain other relevant
financial and operating data of GMC made available to FLCI from published
sources and from the internal records of GMC; (ii) reviewed certain internal
financial and operating information, including certain projections, relating to
GMC prepared by the management of GMC; (iii) discussed the business, financial
condition and prospects of GMC with certain of its officers; (iv) reviewed the
recent reported prices and trading activity for the common stock of GMC and
compared such information and certain financial information for GMC with similar
information for certain other companies engaged in businesses FLCI considered
comparable; (v) reviewed the financial terms, to the extent publicly available,
of certain comparable merger and acquisition transactions; (vi) reviewed the
Agreement; and (vii) performed such other analyses and examinations and
considered such other information, financial studies, analyses and
investigations and financial, economic and market data as FLCI deemed relevant.
 
FLCI did not assume responsibility for independent verification of any of the
information concerning GMC considered in connection with its review of the
Merger and, for purposes of its opinion, FLCI assumed and relied upon the
accuracy and completeness of all such information. FLCI assumed that there has
been no material change in GMC's assets, financial condition, results of
operations, business or prospects since the respective dates of their last
financial statements. FLCI relied on advice of counsel and independent
accountants to GMC as to all legal and financial reporting matters with respect
to GMC, the Merger and the Agreement, including the legal status and financial
reporting of litigation involving GMC. FLCI assumed that the Merger will be
consummated in a manner that complies in all respects with the applicable
provisions of the Securities Act of 1933, as amended (the "Securities Act"), the
Securities Exchange Act of 1934, as amended, and all other applicable federal
and state statutes, rules and regulations. In connection with its opinion, FLCI
did not prepare or obtain any independent evaluation or appraisal of any of the
assets or liabilities of GMC, nor did it conduct a physical inspection of the
properties and facilities of GMC. With respect to the financial forecasts and
projections used in its analysis, FLCI assumed that they reflected the best
currently available estimates and judgments of the expected future financial
performance of GMC. For the purposes of its opinion, FLCI also assumed that GMC
was not a party to any pending transactions, including external financings,
recapitalizations or merger discussions, other than the Merger and those in the
ordinary course of conducting their respective businesses. FLCI's opinion is
necessarily based upon market, economic, financial and other conditions as they
existed and can be evaluated as of the date of the opinion and any subsequent
change in such conditions would require a reevaluation of such opinion.
 
The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The summary
of the FLCI analyses
 
                                       25
<PAGE>   35
 
set forth below does not purport to be a complete description of the
presentation by FLCI to the GMC Board. In arriving at its opinion, FLCI did not
attribute any particular weight to any analysis or factor considered by it but
rather made qualitative judgments as to the significance and relevance of each
analysis and factor. Accordingly, FLCI believes that its analyses and the
summary set forth below must be considered as a whole and that selecting
portions of its analyses without considering all analyses or of the following
summary , without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the FLCI
presentation to the GMC Board and its opinion. In performing its analyses, FLCI
made numerous assumptions with respect to industry performance, general business
and economic conditions and other matters, many of which are beyond the control
of GMC. The analyses performed by FLCI (and summarized below) are not
necessarily indicative of actual values or actual future results which may be
significantly more or less favorable than suggested by such analyses.
Additionally, analyses relating to the values of businesses do not purport to be
appraisals or to reflect the prices at which businesses actually may be
acquired.
 
The following is a brief summary of certain financial analyses performed by FLCI
in connection with providing its written opinion to the GMC Board on November
12, 1998.
 
Analysis of Publicly Traded Comparable Companies:  FLCI compared selected
historical and projected financial information of GMC to publicly traded
companies FLCI deemed to be comparable to GMC. Such information included the
ratios of market value and enterprise value (market value plus debt less cash)
on a per share basis to latest twelve months' earnings per share, projected
earnings per share, book value per share and latest twelve months revenue per
share. FLCI examined eleven such companies and focused on six companies with
market capitalizations under $100 million. FLCI noted high, low, mean and median
share price multiples for the comparable companies of 17.8, 9.5, 12.3 and 11.0
times latest twelve months earnings per share, respectively; 18.1, 6.5, 12.7 and
13.0 times projected earnings per share, respectively; 1.8, 0.7, 1.2 and 1.3
times book value per share, respectively; and 2.1 0.5, 1.3 and 1.2 times latest
twelve months revenue per share, respectively. FLCI also noted high, low, mean
and median enterprise value multiples of 15.5, 11.1, 12.3 and 10.2 times latest
twelve months earnings per share, respectively; 21.7, 12.8, 12.7 and 11.5 times
projected earnings per share, respectively; 1.6, 1.2, 1.2 and 1.3 times book
value per share, respectively; and 2.0, 1.2, 1.2 and 1.2 times latest twelve
months revenue per share, respectively.
 
Discounted Cash Flow Analysis:  FLCI performed a discounted cash flow analysis
for GMC using projected financial performance through 2003 derived from
projections prepared by GMC management. The analysis aggregated (i) the present
value of the projected free cash flow (defined as earnings before interest and
taxes ("EBIT"), less increases in working capital, plus depreciation and
amortization, and less capital expenditures) through 2003 and (ii) the present
value of a range of terminal values (the hypothetical value of selling the
enterprise in its entirety at some future date) for the year 2003. The terminal
values for GMC were determined by applying multiples ranging from six to eight
times GMC's estimated EBIT in 2003 (or 9.8 to 13.0 times net income). GMC's free
cash flow streams and terminal values were discounted to present values using
discount rates ranging from 15% to 25%. Such analysis indicated a range of
equity values for GMC of between $9.40 per share and $17.34 per share with a
mean of $12.97 per share and a median of $12.77 per share.
 
Premium Analysis:  FLCI compared the cash offer price per share for each share
of GMC common stock to the last sale price of GMC Common Stock on both one day
and
 
                                       26

four weeks prior to the announcement of the Merger to similar premiums for
certain defense aerospace electronics company transactions announced since 1996.
FLCI analyzed eleven such public company defense aerospace transactions and
focused on a subset of six transactions in which the value of the transactions
was below $500 million. FLCI observed that the median one trading day premium
and four-week premium paid in six transactions with values below $500 million
were 37.3% and 34.3%, respectively. This compared with the proposed acquisition
in which the one trading day premium of the cash offer price per share over the
closing price of GMC common stock was 69.4% and the four-week premium of the
cash offer price per share over the closing price of GMC common stock was 84.6%.
 
Analysis of Selected Merger and Acquisition Transactions:  FLCI compared the
Merger with selected merger and acquisition transactions for eleven companies in
the defense aerospace industry and focused on six transactions with values below
$500 million. In examining these transactions, FLCI analyzed certain income
statement and balance sheet parameters of the acquired companies relative to the
consideration offered. High, low, mean and median multiples of latest twelve
months revenue were 2.1, 0.6, 1.3 and 1.6 times, respectively, which compared to
1.0 times latest twelve months revenue for GMC in the Merger. FLCI also noted
high, low, mean and median multiples of book value of 3.0, 1.3, 2.0 and 2.1
times, respectively, compared to 1.5 times book value for GMC in the Merger.
 
No company or transaction used in the above analyses is identical to GMC or the
Merger. Accordingly, an analysis of the results of the foregoing is not
mathematical; rather it involves complex considerations and judgments concerning
differences in financial and operating characteristics between GMC and the
company or companies to which it is being compared.
 
The foregoing description of FLCI's opinion is qualified in its entirety by
reference to the full text of such opinion which is attached as Annex C to this
Registration Statement.
 
FLCI, as part of its investment banking services, is regularly engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, strategic transactions, negotiated underwritings, private
placements and valuations for corporate and other purposes. In the past, FLCI
has provided financial advisory services to GMC and has received fees for
rendering these services. In addition, Edmond D. Franco, an executive officer
and holder of a significant percentage of the common stock of FLCI, is a member
of the Board of Directors of GMC.
 
GMC has agreed to pay FLCI a fairness opinion fee of $125,000 in connection with
the delivery of its fairness opinion. GMC also has agreed to reimburse FLCI for
its reasonable out-of-pocket expenses and to indemnify FLCI against certain
liabilities, including liabilities under the federal securities laws or relating
to or arising out of FLCI's engagement.
 
INTERESTS OF CERTAIN PERSONS
 
EMPLOYMENT AND CONSULTING AGREEMENTS
 
The Agreement provides that four of GMC's Executives -- Mitchell Tuckman, Arnold
H. Levine, Rozalie Schachter and Howard Cohen -- will become executive employees
of Herley at the Effective Time of the Merger pursuant to employment agreements
between such persons and Herley having a term of two years. The terms of
employment contained
 
                                       27
<PAGE>   37
 
in such agreements are substantially similar to the terms governing such
persons' current employment by GMC.
 
Sherman A. Rinkel, GMC's Chairman, will become a consultant to Herley pursuant
to a consulting agreement which commences upon the closing of the Merger and
terminates, if not otherwise extended, two years thereafter. Mr. Rinkel is
currently employed as a consultant by GMC upon terms and conditions
substantially similar to those contained in such consulting agreement.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
At the Effective Time of the Merger, Acquisition will cease to exist and all
shares of GMC common stock (other than shares held in the treasury of GMC or
owned by Acquisition, Herley or any wholly-owned subsidiary of Herley or GMC)
will be converted into the right to receive cash and Warrants under the terms of
the Merger or, where applicable, will be represented by dissenters' rights
pursuant to Section 623 of the NYBCL. If all shares of GMC common stock are
exchanged pursuant to the terms of the Merger (other than treasury shares or
shares owned by Acquisition, Herley or any wholly-owned subsidiary of Herley or
GMC), holders of shares of GMC common stock and/or options to acquire shares of
GMC common stock will hold Warrants entitling such holders, in the aggregate, to
acquire 848,675 and 118,000 shares of Herley common stock in respect of shares
of GMC common stock and options to purchase, respectively. As of December 1,
1998, there were 5,295,540 shares of Herley common stock currently issued and
outstanding, 1,485,000 shares of Herley common stock reserved for issuance
pursuant to outstanding warrants and 3,349,483 shares of Herley common stock
reserved for issuance under various stock option plans.
 
APPRAISAL RIGHTS
 
Section 910 of the NYBCL provides that any holder of GMC common stock as of the
GMC Record Date who has not voted in favor of the Agreement has the right, as an
alternative to receiving the merger consideration set forth in the Agreement, to
receive payment of the judicially determined "fair value" of his or her shares
as of the date prior to the GMC Meeting, as well as certain other rights and
benefits ("Appraisal Rights"), subject to Section 623 of the NYBCL. The
shareholders of record of GMC common stock which are eligible to, and do,
exercise their Appraisal Rights with respect to the Merger are referred to
herein as "GMC Dissenting Shareholders," and the shares of stock with respect to
which they exercise Appraisal Rights are referred to herein as "Dissenting
Shares." If a GMC shareholder has a beneficial interest in shares of GMC common
stock that are held of record in the name of another person, and such
shareholder desires to perfect whatever Appraisal Rights such beneficial
shareholder may have, such beneficial shareholder must act promptly to cause the
shareholder of record timely and properly to follow the steps summarized below.
 
Pursuant to the NYBCL, a shareholder of GMC may dissent from the proposed
corporate action to approve the Agreement and receive the right to an appraisal
of such shareholder's shares. If the Merger is consummated, the GMC Dissenting
Shareholders will be entitled, if they strictly comply with the provisions of
the NYBCL, to have the fair value of their shares judicially determined and paid
to them. The following discussion is not a complete statement of the NYBCL
relating to Appraisal Rights, and is qualified in its entirety by reference to
Sections 623 and 910 of the NYBCL attached to this Proxy Statement/Prospectus
as Annex D and incorporated herein by reference. This discussion and
 
                                       28
<PAGE>   38
 
Sections 623 and 910 of the NY Corporation Law should be reviewed carefully by
any shareholder who wishes to exercise statutory Appraisal Rights or wishes to
preserve the right to do so, since failure to comply with the required
procedures will result in the loss of such rights. A shareholder of GMC who
votes for the adoption and approval of the Merger will be deemed to have waived
his or her rights to exercise Appraisal Rights with respect to all shares of GMC
common stock held by such shareholder. Any holder who is considering dissenting
should consult his or her legal advisor.
 
1. A shareholder who wishes to assert his or her legal right to dissent must
   file a written objection to the Merger with GMC either prior to the Meeting
   or at the Meeting prior to the vote with respect to the approval of the
   Agreement. The objection must include a notice of the shareholder's election
   to dissent with respect to all of his or her shares. A GMC Dissenting
   Shareholder may not vote for the Merger and retain Appraisal Rights.
 
2. Within ten days of shareholder approval of the Merger, GMC must give each GMC
   Dissenting Shareholder written notice by registered mail of such approval.
 
3. A notice of election to dissent may be withdrawn by a GMC Dissenting
   Shareholder at any time prior to his or her written acceptance of an offer
   made by GMC or the surviving corporation, as the case may be; but not later
   than sixty days after the Effective Time of the Merger.
 
4. At the time of filing an objection or within one month thereafter, a GMC
   Dissenting Shareholder must submit the certificates representing the
   Dissenting Shares to the surviving corporation or its transfer agent. A GMC
   Dissenting Shareholder who fails to timely submit his or her share
   certificates may lose Appraisal Rights.
 
5. No later than ninety days following the date of the approval of the Merger,
   the surviving corporation shall make a written offer by registered mail to
   each GMC Dissenting Shareholder to pay a specified price for Dissenting
   Shares. Such offer must be accompanied by an advance payment for not less
   than eighty percent of the value of the offer.
 
6. If the GMC Dissenting Shareholder rejects GMC's offer of payment, GMC may,
   within twenty days of the expiration of any applicable time period, institute
   a special proceeding in the Supreme Court of the State of New York to
   determine the rights of GMC Dissenting Shareholders. If GMC does not initiate
   any such action, any GMC Dissenting Shareholder who has rejected GMC's offer
   may do so within the thirty days immediately following on behalf of himself
   and all other GMC Dissenting Shareholders who have rejected GMC's offer. The
   failure to initiate any such action within the period specified shall be
   deemed a waiver of all Appraisal Rights.
 
7. Normally, the parties must bear their own costs and expenses in connection
   with a judicial determination of dissenters' rights.
 
CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
The following describes the principal federal income tax consequences of the
Merger, assuming that the Merger is consummated as contemplated herein, and of
the ownership of the Warrants. The discussion assumes that a GMC shareholder
holds its GMC common stock and will hold its Warrants as capital assets (i.e.,
generally for investment). This discussion is based on current laws and
interpretations thereof, and there can be no assurance that future legislation,
regulations, administrative rulings, or court decisions will not adversely
affect the accuracy of the statements contained herein. The discussion does not
take account of rules that may apply to stockholders that are subject to special
                                       29
<PAGE>   39
 
treatment under federal income tax laws (including, without limitation, trusts,
S corporations, taxpayers subject to alternative minimum tax, insurance
companies, dealers in securities, certain retirement plans, financial
institutions, tax exempt organizations, holders who are not United States
citizens or residents, GMC shareholders who acquired GMC common stock pursuant
to the exercise of employee stock options or rights or otherwise as
compensation, and persons in special situations, including persons who hold
shares of GMC common stock as part of a straddle). No rulings have been
requested or received from the Internal Revenue Service (the "IRS") as to the
matters discussed herein and there is no intent to seek any such rulings.
Accordingly, no assurance can be given that the IRS will not challenge the tax
treatment of certain matters discussed in this summary or, if it does challenge
the tax treatment, that it will not be successful.
 
THE DISCUSSION BELOW DOES NOT ADDRESS STATE, LOCAL OR FOREIGN TAX CONSEQUENCES
OF THE MERGER OR THE OWNERSHIP OF WARRANTS AND THE SPECIFIC TAX CONSEQUENCES TO
EACH GMC SHAREHOLDER MAY DIFFER. CONSEQUENTLY, EACH GMC SHAREHOLDER SHOULD
CONSULT ITS OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES, INCLUDING THE
APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO IT, OF THE
MERGER AND THE OWNERSHIP OF WARRANTS.
 
GMC SHAREHOLDERS
 
Effect of Merger
 
For each holder of GMC common stock, the Merger will be a taxable transaction
for federal income tax purposes and such holder will be treated as if, at the
Effective Time of the Merger, it had sold each of its shares for cash and a
Warrant. A holder of GMC common stock will recognize capital gain or loss equal
to the difference between (x) its tax basis in the GMC common stock surrendered
and (y) the sum of (i) any cash received, plus (ii) the fair market value of the
Warrants received, determined as of the Effective Time.
 
The gain or loss recognized as a result of the Merger will be treated as a
capital gain or loss, provided that GMC is not treated for federal income tax
purposes as a "collapsible corporation." GMC's management believes that GMC is
not a collapsible corporation for federal income tax purposes. For federal
income tax purposes capital losses are generally deductible only against capital
gains and not against ordinary income.
 
Holding of Warrants
 
Warrants received by a holder of GMC common stock in exchange for GMC common
stock will have a tax basis equal to the fair market value of each Warrant
received and the Effective Time will commence a new holding period for that
Warrant.
 
Exercise of Warrants
 
Generally, no gain or loss will be recognized for federal income tax purposes
upon exercise of a Warrant. The tax basis of shares of Herley common stock
acquired upon exercise of a Warrant will be equal to the sum of (i) the holder's
tax basis in such Warrant and (ii) the exercise price. The holding period of the
Herley Common Stock acquired upon exercise of a Warrant will begin on the date
of exercise of the Warrant.
 
                                       30
<PAGE>   40
 
Disposition of Warrants
 
In general, the sale, exchange or other taxable disposition of a Warrant will
result in gain or loss to the holder in an amount equal to the difference
between the amount realized on such sale, exchange or other disposition and the
holder's tax basis in the Warrant. Such gain or loss generally will be long-term
capital gain or loss if the Warrant is held by the holder for more than one year
at the time of the disposition and the Herley Common Stock issuable upon
exercise of such Warrant would have been a capital asset if acquired by the
holder.
 
Expiration of Warrants
 
The expiration of a Warrant should generally result in a long-term capital loss
to the holder equal to the holder's tax basis in the Warrant if the Warrant is
held by the holder for more than one year at the time of the expiration and the
Herley common stock issuable upon exercise of the Warrant would have been a
capital asset if acquired by such stockholder.
 
Backup Withholding
 
Under the federal income tax backup withholding rules, unless an exemption
applies, the Payment Agent will be required to withhold, and will withhold, 31%
of all payments to which a payee is entitled pursuant to the Merger, unless the
payee provides a tax identification number (social security number, in the case
of an individual, or employer identification number in the case of other GMC
shareholders) and certifies under penalties of perjury, that such number is
correct. Each holder of GMC common stock, and, if applicable, each other payee,
should complete and sign the substitute Form W-9 which will be included as part
of the letter of transmittal to be returned to the Payment Agent in order to
provide the information and certification necessary to avoid backup withholding,
unless an applicable exception exists and is proved in a manner satisfactory to
the Payment Agent. The exceptions provide that certain holders (including, among
others, all corporations and certain foreign individuals) are not subject to
these backup withholding and reporting requirements. Any amounts withheld will
be allowed as a credit against the holder's federal income tax liability for
such year.
 
HERLEY, ACQUISITION AND GMC
 
Effect of Merger
 
The merger of Acquisition into GMC, with GMC surviving and with GMC shareholders
receiving the merger consideration in the transaction, constitutes a taxable
reverse subsidiary merger which will be treated for federal income tax purposes
as a direct purchase by Herley of the GMC common stock from the GMC shareholders
in exchange for the merger consideration, and as such the transitory existence
of Acquisition as the wholly-owned subsidiary of Herley will be disregarded for
federal income tax purposes. Because Herley will be treated as purchasing the
GMC common stock directly from the GMC shareholders, unless a Code Section 338
election is made (or is deemed to have been made under the Code) to treat the
purchase by Herley of the GMC common stock as a purchase of the assets of GMC
resulting in a stepped up basis in the GMC assets, no gain or loss will be
recognized by GMC as a result of the Merger. Further, no gain or loss will be
recognized by Herley upon the receipt of the shares of GMC common stock from the
GMC shareholders in exchange for the merger consideration. Herley's adjusted tax
basis in the GMC common stock acquired in the Merger will generally be equal to
the
 
                                       31
<PAGE>   41
 
value of the merger consideration paid by Herley to the GMC shareholders in
exchange for such GMC common stock.
 
THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY. STOCKHOLDERS SHOULD NOTE THAT THE PARTIES HAVE NOT OBTAINED,
AND WILL NOT OBTAIN, A RULING FROM THE IRS OR AN OPINION OF COUNSEL REGARDING
THE MATTERS DESCRIBED HEREIN. EACH STOCKHOLDER IS URGED TO CONSULT HIS, HER OR
ITS TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO THE STOCKHOLDER OF THE
PROPOSED TRANSACTIONS, INCLUDING FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES.
 
ACCOUNTING TREATMENT
 
The Merger will be accounted for as a "purchase" as such term is used under
generally accepted accounting principles. Accordingly, from and after the
Effective Time, GMC's consolidated results of operations will be included in
Herley's consolidated results of operations. For purposes of preparing Herley's
consolidated financial statements, Herley will establish a new accounting basis
for GMC's assets and liabilities based upon the estimated fair market values
thereof and Herley's purchase price, including the costs of the acquisition.
Accordingly, the purchase accounting adjustments made in connection with the
development of the pro forma combined condensed financial information appearing
elsewhere in this Proxy Statement/Prospectus are preliminary and have been made
solely for purposes of developing such pro forma combined condensed financial
information to comply with disclosure requirements of the Securities and
Exchange Commission (the "Commission"). Although the final allocation may
differ, the pro forma combined condensed financial information reflects Herley
management's best estimate based upon currently available information. See
"Unaudited Pro Forma Financial Information."
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
Herley and GMC are aware of no governmental or regulatory approvals required for
consummation of the Merger, other than compliance with the federal securities
laws and applicable state securities and "blue sky" laws.

                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT
 
THE FOLLOWING IS A SUMMARY OF CERTAIN MATERIAL PROVISIONS OF THE AGREEMENT NOT
SUMMARIZED ELSEWHERE IN THIS PROXY STATEMENT/PROSPECTUS. THE FOLLOWING SUMMARY
DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
THE AGREEMENT, A COPY OF WHICH IS ATTACHED AS ANNEX A TO THIS PROXY
STATEMENT/PROSPECTUS AND AMENDMENT NO. 1 TO THE AGREEMENT, A COPY OF WHICH IS
ATTACHED AS ANNEX B TO THIS PROXY STATEMENT/PROSPECTUS.
 
EFFECTIVE TIME
 
The Merger will become effective upon the filing of a Certificate of Merger with
the Secretary of State of New York or at such later time as may be specified in
the Certificate of Merger (the "Effective Time"). The Closing Date will occur as
soon as practicable (but no later than three business days) following the
approval of the Merger by GMC's shareholders, except that the Closing Date may
be adjourned in the event that a condition of closing has not been satisfied or
waived, in which case the Closing Date shall be no later than three business
days following the satisfaction or waiver of any such condition or at such other
time as GMC and Acquisition may agree. Assuming all conditions to the Merger are
met or waived prior thereto, it is anticipated that the Closing Date and
Effective Time will be on or about January 8, 1999.
 
CONVERSION OF SHARES AND OPTIONS
 
At the Effective Time, Acquisition will merge with and into GMC and Herley will
own all of the capital stock of GMC. By virtue of the Merger and without any
action on the part of the holders thereof: (a) all shares of GMC common stock
held in the Treasury of GMC will be cancelled and retired; and (b) each then
outstanding share of GMC common stock, other than shares of GMC common stock
held by persons exercising dissentersI rights under Section 623 of the NY
Corporation Law and shares held in the treasury of GMC or owned by Acquisition,
Herley or any wholly-owned subsidiary of Herley or GMC, will be converted into
the right to receive $18.00 in cash and a Warrant evidencing the right to
purchase one share of Herley common stock at an exercise price of $14.40 until
January 11, 1999, and $15.60 thereafter.
 
All outstanding options to purchase shares of GMC common stock shall, whether or
not exercisable or vested, become fully exercisable and vested. At the Effective
Time, each option to purchase a share of GMC common stock shall be cancelled in
exchange for the right to receive an amount equal to the difference between
$18.00 and the exercise price thereof plus a Warrant to purchase one share of
Herley common stock. There are outstanding options to acquire 88,000 shares of
GMC common stock under GMC's 1990 Stock Option Plan and 30,000 shares of GMC
common stock under the 1997 Non-Employee Director Stock Option Plan.
 
At or before the Effective Time, Acquisition shall make available to American
Stock Transfer & Trust Company, as paying agent (the "Paying Agent"), sufficient
funds and Warrants to satisfy the obligations to holders of shares of GMC common
stock. Promptly after the Effective Time, the Paying Agent shall mail to each
record holder of shares of GMC common stock and each option holder previously
identified by GMC a letter of transmittal and instructions for use in
surrendering certificates representing shares of GMC common stock, presenting
claims with respect to options to purchase outstanding shares and receiving
payment therefor. Any portion of the payment fund, whether as cash or
 
                                       33
<PAGE>   43
 
Warrants, not disbursed within twelve months of the Effective Time will be paid
over to Acquisition.
 
STOCK EXCHANGE LISTING
 
The Warrants to be issued in connection with the Merger will be listed on
NASDAQ. The approval of NASDAQ for listing the Warrants is expected to be
obtained prior to the Effective Time, subject to official notice of issuance.
For a further description of the terms of the Warrants, see "Description of
Herley Capital Stock -- Description of Warrants."

and to carry on its business in the usual, regular and ordinary course, in
substantially the same manner as heretofore conducted, to pay its debts and

      plan.
 
(p)   No Other Negotiations.  Prior to the earlier of the Closing or the
      termination of the Agreement, GMC shall not directly or indirectly
      solicit, initiate or encourage inquiries or proposals with respect to,
      furnish any information relating to, or participate in, continue or enter
      into any negotiations or discussions concerning, any merger, consolidation
      or other business combination with or the purchase of all or a portion of
      the assets of, or any equity interest in GMC or any of its subsidiaries;

      receive.
 
EXPENSES
 
All fees and expenses incurred in connection with the Agreement and the
transactions contemplated thereby will be paid by the party incurring such

INDEMNIFICATION
 
By approving the Agreement, the directors of GMC agreed to waive and not assert
any claims for indemnification which they may have against the surviving
corporation after the Merger to the extent of any increase after the Closing
Date in the market value of the surviving corporation. The surviving corporation
shall retain liability for any claims to indemnification to the extent that such
claims are covered by GMC's existing liability insurance, which insurance is
anticipated to continue for a three-year period after the Effective Time.
 
Section 722 of the NYBCL provides for the indemnification of directors,
officers, employees and agents of a corporation and for persons who serve at its
request as directors, officers, employees or agents of another entity, provided
that such persons have acted in good faith for a purpose he or she reasonably
believed to be in or not opposed to the best
 
                                       37
<PAGE>   47
 
interests of the corporation, in addition, had no reasonable cause to believe
his or her conduct was unlawful.
 
Acquisition's Certificate of Incorporation includes a provision eliminating the
personal liability of directors to the extent permitted by law. Acquisition's
By-laws also provide indemnification to directors and officers and permit
indemnification for employees and agents, including against claims brought under
state or Federal securities laws, to the full extent allowable under New York
law.
 
Section 145 of the Delaware Corporation Law provides that indemnification of
directors, officers, employees and other agents of a corporation, and persons
who serve at its request as directors, officers, employees or other agents of
another organization, may be provided by it.
 
Herley's Certificate of Incorporation includes provisions eliminating the
personal liability of Herley's directors for monetary damages resulting from
breaches of their fiduciary duty except, pursuant to the limitations of the
Delaware General Corporation Law (i) for any breach of the director's duly of
loyalty to Herley or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the Delaware General Corporation Law, or any
amendatory or successor provision thereto, or (iv) with respect to any
transaction from which the director derived an improper personal benefit.
Herley's By-laws provide indemnification to directors and officers and permits
indemnification for employees and agents, including against claims brought under
state or Federal securities laws, to the full extent allowable under Delaware
law. Herley also has entered into indemnification agreements with its directors
and executive officers providing, among other things, that Herley will provide
defense costs against any such claim, subject to reimbursements in certain
events. Herley also maintains a directors and officers liability insurance
policy.

                           COMPARATIVE PER SHARE DATA
 
The following table sets forth certain historical per share data of Herley and
GMC, and combined per share data on an unaudited pro forma basis after giving
effect to the Merger on a purchase basis of accounting, assuming that $18.00 is
paid in cash and one Warrant to purchase one share of Herley common stock is
issued in exchange for one share of GMC common stock in the Merger. The
historical book value per share was calculated by dividing shareholders' equity
by the number of shares of common stock outstanding at the end of each period.
The pro forma combined book value per share was calculated by dividing pro forma
combined shareholders' equity by the number of Herley common shares outstanding
at the end of the period, and does not assume the exercise of any Warrants. This
data should be read in conjunction with the selected historical financial data,
the unaudited pro forma combined condensed financial information and the
separate historical financial statements of Herley and GMC and notes thereto,
included elsewhere in this Proxy Statement/Prospectus. The pro forma combined
per share data is not necessarily indicative of the operating results that would
have been achieved had the Merger been consummated as of the beginning of the
periods presented and should not be construed as representative of future
operations.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
 
The following unaudited pro forma combined condensed financial statements assume
a business combination between Herley and General Microwave Corporation (GMC)
accounted for as a purchase. The pro forma combined condensed statements of
income combine Herley's historical results for the fiscal year ended August 2,
1998 with the historical results of GMC for the twelve-month period ended August
29, 1998. The unaudited pro forma combined condensed balance sheet combines
Herley's August 2, 1998 consolidated balance sheet with GMC's August 29, 1998
consolidated balance sheet.
 
The unaudited pro forma combined condensed financial statements do not reflect
the cost savings and synergies which might be achieved from the merger. The
unaudited pro forma combined condensed financial statements do not purport to be
indicative of the operating results or financial position that would have been
achieved had the merger been effected on the date or dates indicated or the
results which may be obtained in the future.
 
These pro forma statements are based on, and should be read in conjunction with,
the audited consolidated financial statements, including the notes thereto, of
Herley and GMC included elsewhere in this Proxy Statement/Prospectus.

         NOTES TO THE PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1.    The unaudited pro forma combined condensed financial statements reflect
      the acquisition by Herley of all of the issued and outstanding common
      stock of General Microwave Corporation (GMC), including outstanding stock
      options, for $18.00 per share and an estimated 966,675 three-year Warrants
      to purchase one share of Herley's common stock. The Warrants are valued at
      the average of the trading price of similar warrants currently on the
      market of $.625 per Warrant. This average is based on the trading history
      during October 1998. The aggregate estimated purchase price is calculated
      as follows (in thousands, except per share and per share data):
 
<TABLE>

2.    Herley's fiscal year ends on the Sunday closest to July 31. In the
      accompanying unaudited combined condensed pro forma statements of income
      the results of Herley's fiscal year ended August 2, 1998 have been
      combined with the unaudited results of GMC for the twelve-month period
      ended August 29, 1998. The unaudited pro forma condensed financial
      statements have been derived from the audited financial statements of
      Herley as of and for the fiscal year ended August 2, 1998 and the
      unaudited financial statements of GMC as of and for the twelve-month
      period ended August 29, 1998. GMC's fiscal year ends on February 28,
      however, in order to present GMC's operating results on a basis more
      consistent with Herley's fiscal year, the unaudited statement of
      operations of GMC for the twelve-month period ended August 29, 1998 was
      used. The GMC unaudited statement of operations for the twelve-month
      period ended August 29, 1998 was derived from the unaudited interim
      financial statements of GMC for the three-month periods ended November 29,
      1997, February 28, 1998, May 30, 1998 and August 29, 1998.
 
3.    This adjustment reflects the excess of consideration over net assets
      acquired. The following is a calculation (in thousands except per share
      data):
 
<TABLE>
<S>                                                           <C>
Estimated Purchase Price....................................  $23,536
Preliminary purchase accounting adjustments:
  Fair value adjustment to property, plant and equipment....   (7,000)
  Accrual of pension termination costs......................      300
  Deferred tax impact of fair value adjustments.............    2,680
Net book value of GMC net assets acquired as of August 29,
  1998......................................................  (15,239)
                                                              -------
Excess of consideration over net assets acquired............  $ 4,277
                                                              -------
</TABLE>
 
      The total consideration will be allocated to the assets and liabilities of
      GMC based on their estimated fair value. A preliminary allocation by
      Herley of the purchase price has been presented in the pro forma combined
      condensed financial statements in which the historical GMC property, plant
      and equipment has been adjusted to its
 
                                       43
<PAGE>   53
 
      estimated fair value. The impact of this fair value adjustment has also
      been reflected in pro forma deferred tax balances. An additional
      adjustment of the purchase price has been made to accrue for the estimated
      costs associated with the termination of GMC's pension plan. The deferred
      tax impact of this adjustment has also been reflected in the pro forma
      combined condensed financial statements. The excess of consideration over
      the adjusted fair value of GMC net assets acquired has been preliminarily
      allocated to goodwill.
 
      A final allocation of the purchase price to the GMC assets acquired and
      liabilities assumed is dependent upon certain valuations and studies that
      have not progressed to a stage where there is sufficient information to
      make such an allocation in the accompanying pro forma financial
      information.
 
      The allocation of the purchase price of GMC will be revised when
      additional information concerning asset and liability valuations is
      obtained. Adjustments, which could be significant, will be made during the
      allocation period based on detailed reviews of the fair values of assets
      acquired and liabilities assumed and could result in a substantial change
      in goodwill.
 
4.    This entry represents the payment of cash from current available funds to
      the shareholders of the GMC common stock.
 
5.    This adjustment represents additional borrowings under Herley's line of
      credit facility of $9,429,800 for the purpose of financing the remaining
      cash portion of the estimated purchase price.
 
6.    These adjustments represent the elimination of GMC's shareholders' equity
      accounts. Also reflected within the adjustment to additional paid-in
      capital is the recording of the estimated fair value of the Warrants of
      approximately $604,000 to be granted as part of the purchase price. The
      unaudited pro forma combined condensed financial statements do not assume
      the exercise of any Warrants (see Note 1).
 
7.    This entry reflects the adjustment to the amortization for the effect of
      the excess of consideration over net assets acquired. For purposes of the
      pro forma condensed combined financial statements, the Herley management
      expects that amounts allocated to goodwill will be amortized over 20 years
      on a straight-line basis (see Note 3).
 
8.    This entry reflects the adjustment to depreciation expense for the effect
      of the fair value adjustment of GMC's property, plant and equipment based
      on a preliminary evaluation of the fair value (see Note 3).
 
9.    These adjustments represent the recognition of interest expense on the
      additional borrowings of Herley to finance the estimated purchase price
      (see Note 5). The interest expense was calculated based on Herley's
      incremental borrowing rate under its line of credit facility at the
      Federal Funds Target Rate plus 1.65% or approximately 6.45%. A change of
       1/8% in the incremental rate would affect interest expense by $11,787 for
      the fiscal year.
 
10.   The adjustment reflects the loss of interest income generated from the
      cash and cash equivalents that were used to purchase the GMC common stock
      (see Note 4).
 
11.   This entry represents the tax benefit of the pro forma adjustments,
      excluding nondeductible goodwill amortization, of $522,592.

12.   Pro forma per share data are based on the number of Herley common and
      common equivalent shares that would have been outstanding had the
      Herley/GMC merger occurred on the earliest date presented.
 
13.   The effective tax rate for GMC is lower than the statutory tax rate due to
      the reversal of a valuation allowance of $698,000 during the twelve months
      presented that was previously provided against deferred tax assets.
 
14.   Certain amounts have been reclassified to conform to the pro forma
      presentation.

                                     HERLEY
 
GENERAL
 
Herley is engaged in the design, development, manufacture and sale of flight
instrumentation components and systems, and microwave products primarily to the
U.S. government, foreign governments, and aerospace companies. Flight
instrumentation products include command and control systems, transponders,
flight termination receivers, telemetry transmitters and receivers, pulse code
modulator ("PCM") encoders, and scoring systems. Flight instrumentation products
are used to: (i) accurately track the flight of space launch vehicles, targets,
and unmanned airborne vehicles ("UAVs"), (ii) communicate between ground systems
and the airborne vehicle, (iii) if necessary, destroy the vehicle if it is
veering from its planned trajectory, and (iv) train troops and test weapons.
 
Herley's command and control systems are used on training and test ranges
domestically and in foreign countries. Herley has an installed base of
approximately 100 command and control systems around the world, which are either
fixed installations, transportable units or portable units. Herley also
manufactures microwave devices used in its flight instrumentation systems and
products and in connection with the radar and defense electronic systems on
tactical fighter aircraft.
 
Herley has grown internally and through five strategic acquisitions. As a
result, Herley has evolved from a components manufacturer to a systems and
service provider and has leveraged its technical capabilities and expertise into
domestic commercial and foreign defense markets.
 
Since its inception in 1965, Herley has designed and manufactured microwave
devices for use in various tactical military programs. In June 1986, Herley
acquired a small engineering company, Mission Design, Inc., engaged in the
design and development of transponders. This acquisition enabled Herley to enter
the flight instrumentation business beginning with the design and manufacture of
range safety transponders. In September 1992, Herley acquired substantially all
of the assets of Micro-Dynamics, Inc. ("MDI") of Woburn, Massachusetts, a
microwave subsystem designer and manufacturer. In June 1993, Herley acquired
Vega Precision Laboratories, Inc. ("Vega") of Vienna, Virginia, a manufacturer
of flight instrumentation products. In March 1994, Herley entered into an
exclusive license agreement for the manufacture, marketing and sale of the
Multiple Aircraft GPS Integrated Command & Control (MAGIC(2)) systems. In July
1995, Herley acquired certain assets and the business of Stewart Warner
Electronics Corp. of Chicago, Illinois, a manufacturer of high frequency radio
and IFF interrogator systems. In August 1997, Herley acquired Metraplex
Corporation ("Metraplex") of Frederick, Maryland, which has enabled Herley to
enter the airborne PCM and FM telemetry and data acquisition systems market.
 
PRODUCTS
 
COMMAND AND CONTROL SYSTEMS (C(2))
 
For over thirty years, Vega (a division of Herley) has been manufacturing
products in the radar enhancement field. Herley's command and control systems
have been used to fly remotely a large variety of unmanned aerial vehicles,
typically aircraft used as target drones or Remotely Piloted Vehicles ("RPVs")
and some surface targets. Operations have been conducted by users on the open
ocean, remote land masses, and instrumented test and training ranges.
 
                                       46
<PAGE>   56
 
Herley's command and control systems are currently in service throughout the
world. Herley's pulse-positioned-coded ("PPC") concept enables the use of
standard radar technology to track and control unmanned vehicles. Using the
radar beacon mode, PPC pulse groups are transmitted and received for transfer of
command and telemetry data while employing the location precision and advantages
of radar techniques.
 
Command and control systems permit a ground operator to fly a target or a UAV
through a pre-planned mission. That mission may be for reconnaissance, where the
vehicle is equipped with high definition TV sensors and the necessary data links
to send information back to its command and control systems ground station. The
UAV may also be used as a decoy, since the operator can direct the flight
operations that will make the small drone appear to be a larger combat aircraft.
 
With the 1994 licensing of the MAGIC(2) system, Herley increased the selection
of command and control systems. The 6104 TTCS (Target Tracking and Control
System) unit is a line-of-sight command and control system with an installed
base of equipment worldwide. Herley's engineers and marketers are now able to
offer the MAGIC(2) system as a supplement to, or replacement for, this installed
base of equipment. The MAGIC(2) system affords over-the-horizon command and
control using GPS guidance and control of multiple targets from a single ground
station. The ability to control multiple targets at increased distances
represents a significant product improvement. The increasing demand for enhanced
performance by the U.S. Navy as well as foreign navies in littoral warfare
scenarios can be satisfied by the use of the MAGIC(2) system.
 
The new Model 6104 TTCS is a highly flexible, multiple processor design with
high resolution graphics, which can be field configured within minutes to fly or
control any selected vehicle for which it is equipped. The system is designed to
operate with a large variety of vehicles. A basic TTCS configuration is normally
supplied with a standard Herley command panel and the software peculiar to one
vehicle. Telemetry display software is embedded for the specified vehicle, and a
magnetic hard drive is supplied with a mission map prepared in accordance with a
customer supplied detailed map of the area. The TTCS is used in support of
missile, aircraft and other weapons systems development and testing. Herley
continues to provide this system to customers to support their requirement.
 
The MAGIC(2) system provides control of multiple targets from a single ground
control system, and utilizes GPS to provide accurate position information. The
MAGIC(2) system meets a growing requirement to test against multiple threats
with the automated defense capabilities of ships like the AEGIS cruiser and the
E-2C aircraft.
 
Military surveillance operations typically use UAVs, RPVs, or drones to avoid
the cost and risk of manned surveillance vehicles in the event of an accident or
if the vehicle is shot down. These inexpensive drones are controlled in flight
by a Herley command and control system, which may be mounted in a trailer that
may be moved from place to place by helicopter or truck. Herley also
manufactures portable command and control systems that are mounted on tripods
that can be easily transported by an operational team. The portable units permit
ready deployment in rugged terrain and may also be used on ships during open
ocean exercises.
 
In recent years, teaming arrangements between prime military contractors and
Herley have increased. Large companies bidding on major programs seek to align
themselves with parts and systems manufacturers such as Herley for economic
reasons as well as for the technical expertise afforded by such alliances.
Teaming arrangements with Tracor
 
                                       47
<PAGE>   57
 
Corporation and Northrop Grumman Corporation have resulted in recent awards to
Herley for command and control systems in Australia and Singapore, and Herley is
presently negotiating additional teaming arrangements.
 
TELEMETRY SYSTEMS
 
Missile, UAV, or target testing on domestic and international test ranges
requires flight safety and performance data transmission to maximize flight
safety during the test operation. Surveillance and intelligence gathering UAVs
also require a data transmission downlink and a command and control systems
uplink to accomplish their mission. Herley has developed a telemetry system
capability that can be configured to meet individual customers' needs. Various
components of the system include data encoders, transmitters and flight
termination receivers. Each has a distinctive role and each is key to the
success of the mission.
 
In 1972, Metraplex began developing data encoding and acquisition, and signal
conditioning equipment. Metraplex is now a leading manufacturer of PCM and FM
telemetry and data acquisition systems for severe environment applications,
whose products are used worldwide for testing space launch vehicle
instrumentation, aircraft flight testing, and amphibian, industrial and
automotive vehicle testing. The product portfolio ranges in size and complexity
from miniature encoders to completely programmable data acquisition systems.
 
Herley's acquisition of Metraplex in 1997 allows Herley to offer a complete
airborne data link system. With the digital capability of Metraplex in data
encoding and acquisition elements combined with the radio frequency capability
of Herley in providing its telemetry transmitters and flight termination
receivers, Herley offers a full line of narrow or wide band airborne telemetry
systems to meet a wide variety of industrial needs, both domestically and
internationally.
 
TRANSPONDERS
 
Herley manufactures a variety of expendable transponders, including range
safety, identification friend or foe ("IFF"), command and control, and scoring
systems.
 
Transponders are small, expendable, electronic systems consisting of a
transmitter, sensitive receiver and internal signal processing equipment
comprised of active and passive components, including microwave subassemblies
such as amplifiers, oscillators and circulators. The transponder receives
signals from radars, changes and amplifies the frequency of the signals, and
sends back a reply on a different frequency and signal level. This reply will be
a strong, noise free signal upon which the tracking radar can "lock," and one
which is far superior to skin reflection tracking, particularly under adverse
weather conditions after the launch.
 
In range safety applications, transponders enable accurate tracking of space
launch and unmanned aerial vehicles, missiles, and target drones so that
position and direction are known throughout its flight.
 
In the case of several defense and commercial space launch vehicles (i.e.,
Delta, Atlas, Titan and Pegasus), the Herley transponder is tracked by the
ground launch team all the way to space orbit, and in certain instances through
several orbits, as a reference location point in space to assure that the launch
payload has been properly placed in orbit.
 
IFF transponders, which are used in conjunction with the FAA Air Traffic Control
System, enable ground controllers to identify the unmanned targets, drones and
cruise
 
                                       48
<PAGE>   58
 
missiles on which these units fly and to vector other manned aircraft safely
away from the flight path of the unmanned aerial vehicle.
 
Command and control transponders provide the link through the telemetry system
for relaying ground signals to direct the vehicle's flight. The uplink from the
ground control station, a series of coded pulse groups, carries the signals that
command the flight control guidance system of the vehicle. The downlink to the
ground provides both tracking signals for range safety, as well as
acknowledgment and status of the uplink commands and their implementation in the
vehicle. The transponder is therefore the means to fly the vehicle.
 
Scoring systems are mounted on both airborne and sea targets. Scoring systems
enable test and evaluation engineers to determine the "miss-distance" between a
projectile and the target at which it has been launched.
 
FLIGHT TERMINATION RECEIVER
 
A flight termination receiver ("FTR") is installed in a test missile, a UAV, a
target or a space launch vehicle as a safety device. The FTR has a built-in
decoder that enables it to receive a complex series of audio tones which, when
appropriate, will set off an explosive charge that will destroy the vehicle. A
Range Safety Officer ("RSO") using the range safety transponder will track the
vehicle in flight to determine if it is performing as required. If the RSO
detects a malfunction in the test or launch vehicle that causes it to veer from
a planned trajectory in a manner that may endanger personnel or facilities, the
RSO will transmit a coded signal to the onboard FTR to explode the vehicle
harmlessly.
 
MICROWAVE DEVICES
 
Herley manufactures solid state microwave devices in both Lancaster,
Pennsylvania and at its MDI facility in Woburn, Massachusetts for use in its
transponders and existing long-term military programs, both as part of new
production and for spare parts and repair services. These microwave devices are
used in a variety of radar, communications and missile applications, including
airborne and shipboard navigation and missile guidance systems.
 
In Woburn, Herley designs and manufactures complex microwave integrated circuits
("MICs"), which consist of sophisticated assemblies that perform many functions,
primarily involving switching of microwave signals. MICs manufactured by Herley
are employed in many defense electronics military systems as well as missile
programs. Herley also manufactures magnetrons, which are the power source
utilized in the production of Herley's transponders.
 
Herley produces receiver protector devices. These high power devices protect a
radar receiver from transient bursts of microwave energy and are employed in
almost every military and commercial radar system. With the contraction of the
defense business, Herley has only one significant competitor in this market.
 
Herley also designs and manufactures high frequency radio and IFF interrogators.
This high frequency communications equipment is used by the U.S. Navy and
foreign navies that conduct joint military exercises with the U.S. Navy. The IFF
interrogators are used as part of shipboard equipment and are also placed on
coastlines, where they are employed as silent sentries.

NEW PRODUCT DEVELOPMENT AND APPLICATIONS
 
Herley believes that its growth depends, in part, on its ability to renew and
expand its technology, products, and design and manufacturing processes with an
emphasis on cost effectiveness. Herley's primary efforts are focused on
engineering design and product development activities rather than pure research.
A substantial portion of Herley's development activities have been funded by
Herley's customers. Certain of Herley's officers and engineers are involved at
various times and in varying degrees in these activities. Herley's policy is to
assign the required engineering and support people, on an ad hoc basis, to new
product development as needs require and budgets permit. The cost of these
development activities, including employees' time and prototype development, net
of amounts paid by customers, were approximately $1,562,000, $1,828,000, and
$1,453,000 in fiscal 1998, 1997, and 1996, respectively.
 
The new products and systems that Herley plans to design, manufacture and sell
are data link systems, which include telemetry data encoders. Data link systems
and data encoders are currently being sold by others to Herley's existing
customers. With its acquisition of Metraplex in August 1997, Herley now offers
data link systems to its customers, either directly or through teaming
arrangements. Upon receipt of an order, Herley will customize the design of a
system for its customer for delivery typically nine months after receipt of such
order.
 
DATA LINK SYSTEMS
 
Data link systems contain transmitters, amplifiers, receivers and other
components, and provide the means of communication between the control tower,
the ground station and the test or launch vehicle. Data link systems are the
equivalent of telephone links between the air and ground portions of launch
vehicles or test and training ranges. The uplink communication to the airborne
vehicle is transmitted via a telemetry signal from the ground to the vehicle.
The telemetry signals are used to command the airborne vehicle through its
command control transponder. The transponder will then change the flight control
guidance system as directed. The downlink signals from the airborne telemetry
transmitter to the ground telemetry receiver provide tracking signals for range
safety, confirmation of the uplink command and their implementation by the
vehicle and compilation of the data from on-board sensors gathered by the
telemetry data encoder.
 
Through the application of technology acquired from Metraplex, Herley
manufactures data encoders. Airborne targets and flight test missiles must have
many critical parameters simultaneously monitored from the ground to gain the
data required for verification of satisfactory performance or for identification
of details of hardware requiring design improvements. On-board sensors may
measure temperature, strain levels, vibration level and frequency, acoustic
noise levels, air pressure, air velocity, humidity and other parameters of
interest. The function of the encoder system is to convert the output of each of
these sensors to a signal form that may be sequentially sampled by an electronic
switch (multiplexer) produced by Herley in a known sequence and rate so as to
create a data stream that may be transmitted to the ground by the telemetry
system.
 
COMMERCIAL LIGHTING
 
Over the past three years, Herley has been seeking commercial applications for
the magnetron tubes produced by Herley's MDI division. In 1995, Herley signed
agreements with a large lighting company to develop miniature cost-effective
magnetron tubes, using electrode-less high density ("EHD") techniques, for
medical and industrial lighting
 
                                       50
<PAGE>   60
 
applications. Based on initial engineering results, prototype tubes were
designed, manufactured and tested satisfactorily to the specifications required.
Herley and this other company are currently planning limited production of
magnetron tubes to be used in an EHD industrial lighting application.
 
GOVERNMENT CONTRACTS
 
A substantial part of Herley's sales are made to U.S. government agencies, prime
contractors or subcontractors on military or aerospace programs. Government
contracts are awarded either on a competitive bid basis or on a negotiated sole
source procurement basis. Contracts awarded on a bid basis involve several
competitors bidding on the same program with the contract being awarded based
upon price and ability to perform. Negotiated sole source procurement is
utilized if Herley is deemed by the customer to have developed proprietary
equipment not available from other parties or where there is a very stringent
delivery schedule.
 
All of Herley's government contracts are fixed price contracts, some of which
require delivery over time periods in excess of one year. With this type of
contract, Herley agrees to deliver products at a fixed price except for costs
incurred because of change orders issued by the customer.
 
In accordance with Department of Defense procedures, all contracts involving
government programs may be terminated by the government, in whole or in part, at
the government's discretion. In the event of such a termination, prime
contractors on such contracts are required to terminate their subcontracts on
the program and the government or the prime contractor is obligated to pay the
costs incurred by Herley under the contract to the date of termination plus a
fee based on the work completed.
 
MARKETING AND DISTRIBUTION
 
Herley's marketing approach is to determine customer requirements in the
developmental stages of a program. Marketing and engineering personnel work
directly with the customer's engineering group to develop product
specifications. Herley receives its awards based upon an evaluation of a number
of factors, including technical ranking, price, overall capability and past
performance. Follow-up contracts (including options) on the same program are
normally negotiated with customers rather than being subject to a competitive
bidding process.
 
BACKLOG
 
Herley's backlog of firm orders was approximately $38,724,000 on August 2, 1998
($25,727,000 in domestic orders and $12,997,000 in foreign orders) as compared
to approximately $36,911,000 on August 3, 1997 ($26,135,000 in domestic orders
and $10,776,000 in foreign orders). Management anticipates that approximately
$32,093,000 of the backlog will be shipped during the fiscal year ending August
1, 1999. There can be no assurance that Herley's backlog will result in sales in
any particular period or at all, or that the contracts included in backlog that
result in sales will be profitable.
 
MANUFACTURING, ASSEMBLY AND TESTING
 
Flight instrumentation devices manufactured by Herley for military and space
launch applications are subject to testing procedures based upon customer
requests. All of such testing is performed by Herley at its facilities.
 
                                       51
<PAGE>   61
 
All electronic parts are procured in controlled lots that are subjected to
physical inspection and screening at Herley facilities before use in products.
Physical inspection may require the use of high power microscopes and laser
scanned optical comparators, which match the characteristics of the part under
inspection to previously stored images.
 
The testing of high reliability space equipment is performed by complex computer
controlled consoles that continuously monitor, analyze and measure operating
parameters. Flight instrumentation products are tested over their full operating
temperature range, after which the equipment is evaluated under combined
vibration and temperature cycling. For initial design qualification, this
testing may extend for several months and include evaluation of electromagnetic
interference behavior ("EMI"), ability to survive pyrotechnic shock (simulating
explosive charge detonation for space vehicle stage separation) and the combined
effects of external vacuum with heating and cooling.
 
Electronic components and other raw materials used in Herley's products are
purchased by Herley from a large number of suppliers and all of such materials
are readily available from alternate sources, with the exception of one
component part which, if unavailable, can be manufactured by Herley.
 
Herley does not maintain any significant level of finished products inventory.
Raw materials are generally purchased for specific contracts and common
components are purchased for stock based on Herley's firm fixed backlog.
 
There are no significant environmental control procedures required concerning
the discharge of materials into the environment that would require Herley to
invest in any significant capital equipment or that would have a material effect
on the earnings of Herley or its competitive position.
 
COMPETITION
 
The flight instrumentation and microwave products that Herley manufactures are
subject to varied competition depending on the product and market served.
Competition is generally based upon technology, design, price and past
performance. Herley's ability to compete for defense contracts depends, in part,
on its ability to offer better design and performance than its competitors and
its readiness in facilities, equipment and personnel to undertake to complete
the programs. In certain products or programs, Herley believes it is sole
source, which means that all work is directed to a single manufacturer. In other
cases, there may be other suppliers that have the capability to compete for the
programs involved, but they can only enter or reenter the market if the
government should choose to reopen the particular program to competition.
Competition in follow-on procurements is generally limited after an initial
award unless the original supplier has had performance problems. Many of
Herley's competitors are larger and may have greater financial resources than
Herley. Competitors include Aydin Corporation, L-3 Communications Corporation,
Microsystems, Inc., AMP, Inc. and Remec, Inc.
 
EMPLOYEES
 
As of October 4, 1998, Herley employed 306 full-time persons. A total of 228
employees were engaged in manufacturing, 38 in engineering, 19 in marketing,
contract administration and field services and the balance in general and
administrative functions. None of Herley's employees are covered by collective
bargaining agreements and Herley considers its employee relations to be
satisfactory. Herley believes that its future success will depend, in part, on
its continued ability to recruit and retain highly skilled technical, managerial
and marketing personnel. To assist in recruiting and retaining such personnel,
Herley has
 
                                       52
<PAGE>   62
 
established competitive benefits programs, including a 401k employee savings
plan, and stock option plans.
 
INTELLECTUAL PROPERTY
 
Herley does not presently hold any significant patents applicable to its
products. In order to protect its intellectual property rights, Herley relies on
a combination of trade secret, copyright and trademark laws and certain employee
and third-party nondisclosure agreements, as well as limiting access to and
distribution of proprietary information. There can be no assurance that the
steps taken by Herley to protect its intellectual property rights will be
adequate to prevent misappropriation of Herley's technology or to preclude
competitors from independently developing such technology. Trade secret and
copyright laws afford Herley limited protection.

       HERLEY MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE HISTORICAL
FINANCIAL STATEMENTS OF HERLEY, RELATED NOTES AND OTHER FINANCIAL INFORMATION
INCLUDED ELSEWHERE IN THIS PROXY STATEMENT/PROSPECTUS.
 
OVERVIEW
 
Herley is engaged in the design, manufacture and sale of flight instrumentation
components and systems, and microwave products, primarily to the U.S.
government, foreign governments, and aerospace companies. Flight instrumentation
products include command and control systems, transponders, flight termination
receivers, telemetry transmitters and receivers, PCM encoders, and scoring
systems. Flight instrumentation products are used to: (i) accurately track the
flight of space launch vehicles, targets, and UAVs, (ii) communicate between
ground systems and the airborne vehicle, (iii) if necessary, destroy the vehicle
if it is veering from its planned trajectory, and (iv) train troops and test
weapons.
 
Of Herley's total backlog of $38,724,000 at August 2, 1998, $25,727,000 is
attributable to domestic orders and $12,997,000 is attributable to foreign
orders. Management anticipates that approximately $32,093,000 of its backlog
will be shipped during the fiscal year ending August 1, 1999. Herley includes in
its backlog only firm orders for which it has accepted a written purchase order.
In accordance with Department of Defense procedures, all contracts involving
government programs may be terminated by the government, in whole or in part, at
the government's discretion. In the event of such a termination, prime
contractors on such contracts are required to terminate their subcontracts on
the program and the government or the prime contractor is obligated to pay the
costs incurred by Herley under the contract to the date of termination plus a
fee based upon work completed.
 
Substantially all of Herley's contracts are fixed price contracts, wherein sales
and related costs are generally recorded as deliveries are made. Many of these
contracts include options exercisable by the customer for additional products or
systems at a fixed price. Certain costs under long-term fixed price contracts,
principally directly or indirectly with the U.S. Government, which include
non-recurring engineering, are deferred until these costs are contractually
billable. The failure to anticipate technical problems, estimate costs
accurately or control costs during a fixed price contract, including with
respect to any option for additional products or systems, may reduce Herley's
profitability or cause a loss under the contract. Revenue under certain
long-term, fixed price contracts, principally command and control shelters, is
recognized using the percentage of completion method of accounting. Revenue
recognized on these contracts is based on estimated completion to date, which is
the total contract amount multiplied by percent of performance, based on total
costs incurred in relation to total estimated cost at completion. As of August
2, 1998, costs incurred and income recognized in excess of billings on
uncompleted contracts was $1,665,008. There were no long-term contracts of this
nature as of August 3, 1997. Losses, if any, on contracts are recorded when
first reasonably determined.
 
Herley believes that its growth depends on its ability to renew and expand its
technology, products, and design and manufacturing processes with an emphasis on
cost effectiveness. Herley's primary efforts are focused on engineering design
and product development activities, rather than pure research. The cost of these
development activities, including employees' time and prototype development, net
of amounts paid by customers, was
 
                                       54
<PAGE>   64
 
approximately $1,562,000,$1,828,000, and $1,453,000 in fiscal years 1998, 1997
and 1996, respectively. Costs of Herley's internally funded product development
efforts are included in Herley's operating expenses as cost of products sold.
Revenue from customer funded product development is included in net sales and
the related product development costs also are included in cost of products
sold.
 
Herley's effective tax rate for fiscal 1998 and 1997 was 34.8% and 9.1%,
respectively. The low effective rate in 1997 reflects the utilization of prior
year net operating loss carryforwards and the reversal of a valuation allowance
established in 1995. The valuation allowance was established based on
management's uncertainty that past performance would be indicative of future
earnings. In August 1997, Herley established a foreign sales corporation as part
of an overall domestic tax strategy to reduce its effective income tax rate.
 
RESULTS OF OPERATIONS
 
The following table sets forth for the periods indicated certain financial
information derived from Herley's consolidated statements of income expressed as
a percentage of net sales. There can be no assurance that trends in sales growth
or operating results will continue in the future.

</TABLE>
 
FISCAL 1998 COMPARED TO FISCAL 1997
 
Net sales for the 52 weeks ended August 2, 1998 were approximately $40,798,000
compared to $32,195,000 for fiscal 1997. The sales increase of $8,603,000
(26.7%) is primarily attributable to the acquisition of Metraplex Corporation as
of August 4, 1997 which contributed $4,015,000 in revenues in fiscal 1998, an
increase of approximately $3,542,000 in flight instrumentation products, and an
increase of approximately $1,046,000 in microwave components.
 
                                       55
<PAGE>   65
 
Gross profit of 40.8% for the 52 weeks ended August 2, 1998 exceeded the prior
year of 35.5% due to an increase of $2,545,000 in higher margin foreign sales
from $9,398,000 in 1997 to $11,943,000 in 1998, and improved margins in
microwave components, as well as an increase in absorption of fixed costs due to
the higher sales volume.
 
Selling and administrative expenses for the 52 weeks ended August 2, 1998 were
$8,339,000 compared to $6,293,000 for fiscal 1997, an increase of $2,046,000.
The addition of Metraplex Corporation added $1,195,000 in selling and
administrative expenses in fiscal 1998. In addition, $304,000 of the change is
attributable to increased representative fees on foreign sales, $415,000 is due
to increased personnel and related expenses, including additional travel
expenses, and $350,000 relates to increased consulting fees primarily for
software changes addressing the year 2000 computer software issues. Such
increases were offset by cost savings of $243,000 related to the transfer of
substantially all of the production from the Stewart Warner facilities in
Chicago to Herley's facilities in Lancaster, Pennsylvania. As a percentage of
net sales, selling and administrative expenses increased from 19.5% in 1997 to
20.4% in 1998.
 
Other income, net, for the 52 weeks ended August 2, 1998 was consistent with the
prior year.
 
The effective tax rate in 1998 was 34.8% as compared to 9.1% in fiscal 1997. The
1997 tax provision reflects the utilization of prior year net operating loss
carryforwards. In 1995 a valuation allowance had been provided to reduce
deferred tax assets to their net realizable value primarily based on
management's uncertainty that past performance would be indicative of future
earnings. In 1997 the valuation allowance was reversed through the deferred tax
provision. A determining factor in assessing the change was the cumulative
income in recent years.
 
FISCAL 1997 COMPARED TO FISCAL 1996
 
Net sales for the 53 weeks ended August 3, 1997 were approximately $32,195,000
compared to $29,001,000 for fiscal 1996. The sales increase of $3,194,000 (11%)
is primarily attributable to an increase in the sales of flight instrumentation
products, including a Target Tracking Control System for the Republic of Korea.
 
Gross profit of 35.5% for the 53 weeks ended August 3, 1997 exceeded the prior
year of 31.7% due to an increase of $2,842,000 in higher margin foreign sales
from $6,556,000 in 1996 to $9,398,000 in 1997, as well as an increase in
absorption of fixed costs due to the higher sales volume.
 
Selling and administrative expenses for the 53 weeks ended August 3, 1997 were
$6,293,000 compared to $5,832,000 for fiscal 1996, an increase of $461,000 of
which $360,000 was attributable to settlement and litigation costs involving two
class action law suits, $325,000 to performance incentives, and $52,000 to
additional travel costs. These increases were offset by a reduction in
representative fees on foreign sales of $205,000 (partially due to a negotiated
decrease in the rate paid), and a reduction of $75,000 in personnel and related
expenses. As a percentage of net sales, selling and administrative expenses
decreased from 20.1% in 1996 to 19.5% in 1997.
 
Other income, net, for the 53 weeks ended August 3, 1997 decreased $265,000 from
the prior year due to decreases in gains on the sale of investments and dividend
and interest income of $488,000 and $118,000, respectively, offset by a decrease
in interest expense of $341,000.
 
                                       56
<PAGE>   66
 
The effective tax rate in 1997 was 9.1%. The 1997 and 1996 tax provisions
reflect the utilization of prior year net operating loss carryforwards. In 1995
a valuation allowance had been provided to reduce deferred tax assets to their
net realizable value primarily based on management's uncertainty that past
performance would be indicative of future earnings. In 1997 the valuation
allowance was reversed through the deferred tax provision. A determining factor
in assessing the change was the cumulative income in recent years. See Note I
entitled "Income Taxes" to the Consolidated Financial Statements included
elsewhere in this Proxy Statement/Prospectus.
 
LIQUIDITY AND CAPITAL RESOURCES
 
As of August 2, 1998 and August 3, 1997, working capital was approximately
$26,593,000 and $10,662,000, respectively, and the ratio of current assets to
current liabilities was 3.70 to 1 and 2.09 to 1, respectively. At August 2,
1998, Herley had cash and cash equivalents of approximately $10,689,000,
primarily from the proceeds received from the public stock offering discussed
below.
 
On August 4, 1997, the Company completed the acquisition of Metraplex
Corporation, a Maryland corporation for 313,139 (as adjusted) shares of common
stock of Herley, with a fair market value of $3,170,471, in exchange for all of
the issued and outstanding common stock of Metraplex.
 
As is customary in the defense industry, inventory is partially financed by
advance payments. The unliquidated balance of these advance payments was
approximately $1,825,000 in 1998, and $3,091,000 in 1997. The decrease in the
current fiscal year is directly attributable to shipments under the related
contracts.
 
Net cash provided by (used in) operations and investing activities was
approximately $3,647,000, and $6,159,000, respectively in 1997, and
approximately $4,571,000 and ($1,051,000), respectively in 1998.
 
Net cash provided by financing activities in fiscal 1998 consists of net
proceeds of $7,452,000 from the sale of 700,000 shares of common stock, and
1,265,000 Common Stock Purchase Warrants to the public. Net borrowings under a
bank line of credit provided $1,500,000 in financing. Herley received a partial
distribution of $592,824 from its M.D. Sass Municipal Finance Partners-I limited
partnership investment. Cash was used in financing activities for payments of
long-term debt of $2,257,000 and the purchase of treasury stock of $1,084,000.
Cash provided by investing activities in 1997 resulted primarily from the
liquidation of all the available-for-sale securities, and the sale of Herley's
interest in the M.D. Sass Re/Enterprise-II, L.P., limited partnership. Herley
used approximately $9,715,000 of these funds in financing activities primarily
for the net payment of outstanding bank debt of $7,250,000, and the purchase of
treasury stock for $2,783,000.
 
Herley maintains a revolving credit facility with a bank for an aggregate of
$21,000,000, which expires January 31, 2000. As of August 2, 1998, Herley had
borrowings outstanding of $1,500,000. No borrowings were outstanding on this
line at August 3, 1997.
 
In January 1998, Herley purchased 89,888 shares of its outstanding common stock
for $1,084,326 from certain officers of Herley based on the fair market value of
the stock on the date acquired. During the fiscal year ended August 3, 1997,
Herley acquired 244,519 shares of its outstanding common stock for $2,782,686
through open market purchases, pursuant to a stock purchase plan to acquire up
to 300,000 pre-split shares of Herley common stock, which was terminated in June
1997.

Herley also acquired 42,016 and 463,639 shares of common stock in 1998 and 1997,
respectively, valued at $538,376 and $6,429,124, respectively, in connection
with certain "stock-for-stock" exercises of stock options by which certain
employees elected to surrender "mature" shares owned in settlement of the option
price. Such exercises are treated as an exercise of a stock option and the
acquisition of treasury shares by Herley. See "Herley Management and Executive
Compensation."
 
Herley believes that presently anticipated future cash requirements will be
provided by internally generated funds and existing credit facilities, as well
as the proceeds received from the public stock offering.
 
YEAR 2000 READINESS
 
The "Year 2000" problem relates to computer systems that have time and
date-sensitive programs that were designed to read years beginning with "19",
but may not properly recognize the year 2000. If a computer system or software
application used by Herley or a third party dealing with Herley fails because of
the inability of the system or application to properly read the year 2000 the
results could have a material adverse effect on Herley.
 
A substantial part of Herley's revenues are derived from firm fixed price
contracts with U.S. government agencies, prime contractors or subcontractors on
military or aerospace programs, and many foreign governments. If Herley is
unable to perform under these contracts due to a Year 2000 problem, the customer
could terminate the contract for default. While lost revenues from such an event
are a concern for Herley, the greater risks are the consequential damages for
which Herley could be liable for failure to perform under the contracts. Such
damages could have a material adverse impact on Herley's results of operations
and financial position.
 
The most likely reason for a customer to terminate a contract for default would
be due to Herley's inability to manufacture and deliver product under the
contract. Breakdowns in any number of Herley's computer systems and applications
could prevent Herley from being able to manufacture and ship its products.
Examples are failures in Herley's manufacturing application software, computer
chips embedded in engineering test equipment, lack of supply of materials from
its suppliers, or lack of power, heat, or water from utilities servicing its
facilities. Herley's products do not contain computer devices that require
remediation to meet Year 2000 requirements. A review of Herley's status with
respect to remediating its computer systems for Year 2000 compliance is
presented below.
 
For its information technology, Herley currently utilizes a Hewlett Packard
HP3000-based computing environment. Hewlett Packard has advised Herley that the
HP3000 hardware is in compliance with Year 2000 requirements. Herley's
financial, manufacturing, and other software applications related to the HP3000
have been updated to comply with Year 2000 requirements at a cost of
approximately $350,000. Certain modules have been fully tested, with the
remaining modules to be tested by the end of fiscal 1999. In addition, Herley
utilizes a wide area network ("WAN") to connect its operating facilities to the
HP3000. The WAN has been updated to comply with Year 2000 requirements. A local
area network ("LAN") is used to supplement the HP3000 environment and has also
been upgraded and is fully Year 2000 compliant.
 
Herley is also reviewing its utility systems (heat, light, phones, liquid
nitrogen, etc.) for the impact of Year 2000, as well as determining the state of
readiness of its material suppliers. Herley will develop a questionnaire to be
sent to its significant suppliers, and to its test equipment manufacturers
concerning embedded technology, regarding their
 
                                       58
<PAGE>   68
 
compliance and attempt to identify any problem areas with respect to them. This
process will be ongoing and Herley's efforts with respect to specific problems
identified, and future costs associated with them, will depend in part upon its
assessment of the risk that any such problems may cause a disruption in
manufacturing or other problem which Herley believes would have a material
adverse impact on its operations. However, Herley cannot control the conduct of
its suppliers. Therefore, there can be no guarantee that Year 2000 problems
originating with a supplier will not occur. Herley has not yet developed
contingency plans in the event of a Year 2000 failure caused by a supplier or
third party, but would intend to do so if a specific problem is identified
through the process described above. Herley has developed multiple sources for a
substantial portion of its raw material requirements and, therefore, does not
believe there would be a significant disruption in supply.
 
The information set forth above identifies the key steps taken by Herley to
address the Year 2000 problem. There can be no absolute assurance that third
parties will convert their systems in a timely manner. Herley believes that its
actions will minimize these risks and that any additional cost of Year 2000
compliance for its information and production systems will not be material to
its consolidated results of operations and financial position.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
Herley is subject to market risk associated with changes in interest rates and
stock prices. Herley has not entered into any derivative financial instruments
to manage the above risks and Herley has not entered into any market risk
sensitive instruments for trading purposes. Herley's debt consists of a working
capital line of credit with a bank having an interest rate that floats with the
FMOC Target Rate (7.15% as of August 2, 1998), and a mortgage on its facilities
in Lancaster, Pa. at a fixed rate of 10.4% The credit line is reviewed on an
annual basis. After the proposed acquisition of General Microwave Corp. Herley
will be subject to potentially adverse movements in foreign currency rate
changes. Herley does not anticipate any other material changes in its primary
market risk exposures in fiscal 1999.
 
As of August 2, 1998, Herley holds an investment in the common stock of a public
company that is exposed to price risk with a cost basis and a fair market value
basis of $143,330.
 
The table below provides information about Herley's debt that is sensitive to
changes in interest rates. The table presents principal cash flows by maturity
date. Future principal payments required under the mortgage and line of credit,
and corresponding fair values are as follows:

one-third on each of the grant date and on the first and second anniversary of
the grant date.
 
WARRANT AGREEMENTS.  In April 1993, common stock warrants were issued to certain
officers and directors for the right to acquire 573,333 shares of Herley common
stock at an exercise price of $5.3475 per share, which was the closing price of

EMPLOYEE SAVINGS PLAN
 
Herley maintains an Employee Savings Plan that qualifies as a thrift plan under
Section 401(k) of the Internal Revenue Code. This plan allows employees to
contribute between 2% and 15% of their salaries to the plan. Herley, at its
discretion, can contribute 100% of the first 2% of the employees' salary so
contributed and 25% of the next 4% of salary. Additional Herley contributions
can be made, depending on profits. The aggregate benefit payable to an employee
depends upon the employee's rate of contribution, the earnings of the fund, and
the length of time such employee continues as a participant. Herley accrued
approximately $197,000 for the 52 weeks ended August 2, 1998, and contributed
approximately $181,000 and $159,000 to this plan for the fiscal years ended
August 3, 1997 and July 28, 1996, respectively. For the year ended August 2,
1998, $4,800, $4,800, $3,766, and $3,323 was contributed by Herley to this plan
for Messrs. Blatt, Levy, Coon and Garefino, respectively, and $24,328 was
contributed for all officers and directors as a group.

                                      GMC
 
GENERAL
 
GMC is engaged primarily in the design, development, manufacture and marketing
of microwave and electronic systems, equipment and components. GMC is organized
into three operating divisions in three locations with strong inter-divisional
ties. The parent company, General Microwave Corporation, operates GMC's largest
division, its microwave division located in Amityville, New York. A substantial
portion of GMC's microwave products is sold to manufacturers and users of
microwave systems and equipment for applications in the defense electronics
industry. GMC also sells these components and
 
                                       68
<PAGE>   78
 
equipment for use in the industrial sector as well as in commercial
telecommunications industries. Typical applications for GMC's microwave products
include electronic warfare and countermeasures, airborne and shipboard
navigation and communications, radar systems, missile guidance systems,
automatic test equipment, and satellite communications.
 
GMC's subsidiaries, General Microwave Israel Corporation and General Microwave
Israel (1987) Ltd. in Jerusalem, Israel, conduct research and development and
manufacturing operations largely devoted to the production of microwave
oscillators. GMC's subsidiary, General Microcircuits Corporation in Billerica,
Massachusetts, engages in the design, manufacture and sale of hybrid
microcircuits largely intended for military applications.
 
In February, 1997, GMC decided to concentrate on its core businesses and adopted
a plan to exit the fiber optics business of its Math Associates subsidiary. On
September 24, 1997, a sale of certain of the assets of Math was completed. (See
Note 2 to the February 28, 1998 Consolidated Financial Statements included
elsewhere herein.) Accordingly, unless otherwise indicated, all of the
information contained below has been restated to delete data applicable to Math
Associates, Inc. (now known as GMC Associates, Inc.).
 
GMC has traditionally developed new products for sale as standard catalog items
as well as products designed to customer specifications under fixed price
contracts. GMC's catalogs currently list over 300 products.
 
The following table sets forth, for the periods indicated, unaudited information
with respect to GMC's net sales contributed by each class of similar products
which accounted for 15% or more of consolidated net sales in any of the last
three fiscal years.

MARKETING
 
GMC markets its products through an internal marketing department and through
independent domestic and independent foreign sales organizations.
 
RESEARCH AND DEVELOPMENT
 
GMC's research and development is conducted both through internally funded
activities and through customer funded research and development under fixed
price and cost plus fixed fee product development contracts.
 
Internally funded research and development expenditures aggregated $295,500,
$495,000 and $1,090,000 in fiscal 1998, 1997 and 1996, respectively. These
expenditures are net of reimbursements received under agreements with the
government of Israel and another entity in the amounts of $104,000 in fiscal
1996.
 
In addition to GMC sponsored development activities, GMC continues to expand and
improve its product line and technology through performance under certain fixed
price and cost plus fixed fee contracts requiring the development and
manufacture of new products.
 
                                       69
<PAGE>   79
 
Development and manufacturing costs incurred in connection with customer funded
prototype development contracts are included in cost of sales. The estimated
amount spent by GMC during each of the last three fiscal years on customer
sponsored research and development activities aggregated $1,075,000, $350,000
and $625,000 in fiscal 1998, 1997 and 1996, respectively. GMC is currently
engaged in the design and manufacture of new prototypes in connection with
various electronic countermeasures, electronic warfare, radar, navigation and
communications programs of the United States Government. GMC also understands
that many of such engagements by major industrial corporations are for the
design and manufacture of products for foreign governments and agencies thereof.
 
RAW MATERIALS
 
Manufacturing operations consist of fabrication, assembly and testing of
components, systems and equipment built from fabricated parts as well as printed
circuits, electronic materials and components purchased from outside sources.
Manual and semi-automatic methods are employed in the manufacturing process,
depending principally upon production volumes. Inspection and testing are
critical to the achievement of product reliability and performance standards
demanded by GMC's customers. GMC utilizes proprietary and other testing
equipment in its operations and is continuously developing new testing
techniques to maintain its products' performance standards.
 
Electronic components and raw materials used in GMC's products are generally
available from a large number of suppliers. Some materials are standard items
and others are manufactured to GMC's specifications by subcontractors. GMC is
not dependent upon any single supplier for any component or material and has not
experienced significant interruptions in production due to a shortage of raw
materials.
 
PATENTS AND TRADEMARKS
 
GMC has 12 patents in the United States which cover various products. GMC
considers that its competitive position depends more upon the technical
expertise and creative ability of its engineering and development personnel than
upon its patents, patent applications and trademarks.
 
CUSTOMERS
 
GMC's customers consist primarily of the United States Government and major
industrial corporations that incorporate GMC's products into a variety of
military, and to a lesser extent, commercial systems. At present, GMC estimates
that it has approximately 2,500 customers. During fiscal 1998, no customers
other than Litton Systems, Inc. accounted for 10% or more of GMC's net sales.
Litton accounted for approximately 16% of net sales.
 
Although the end-use for GMC's products is not always identifiable, Management
estimates that sales for direct or indirect use by the United States Government
represented approximately 53%, 42% and 55% of GMC's net sales in fiscal 1998,
1997 and 1996, respectively. The timing and level of appropriations by the
federal government can influence GMC's operating results significantly. No
material portion of the Company's business is subject to renegotiation or
limitation of profits on contracts or subcontracts by the federal government.
However, the federal government, or agencies thereof, may terminate their
contracts, in whole or in part, at their convenience. In such event, the
government agency is obligated generally to pay the costs incurred by GMC under
the contract plus a fee based upon work completed. Substantial curtailment or
termination of
 
                                       70
<PAGE>   80
 
the government programs which, directly or indirectly, fund GMC's contracts
could have a material adverse effect upon GMC's operating results.
 
Foreign sales, primarily in Israel, Japan, Norway, United Kingdom, India,
France, Australia and Canada accounted for approximately 34%, 34% and 25% of
GMC's net sales in fiscal 1998, 1997 and 1996, respectively. Foreign sales in
fiscal 1998 include immaterial amounts of direct sales to 5 foreign governments
or agencies thereof.
 
COMPETITION
 
GMC's ability to compete is dependent on several factors, including product
performance, quality and reliability, product development capabilities, price,
and the ability to meet delivery schedules and customer specifications. The
microwave component and equipment markets are highly competitive and are
characterized by rapid advances in technology resulting in the introduction of
new products with improved performance characteristics, thereby subjecting GMC's
products to the risk of technological obsolescence.
 
GMC has numerous competitors, including some of its current customers with
captive microwave component design and manufacturing operations. In addition,
GMC competes with certain of its suppliers of semiconductor devices. GMC also
competes with a variety of companies across its entire product line. Many of
GMC's competitors have greater financial and other resources than does GMC.
 
In response to increased competitive pressure caused by tightened government
purchasing practices, GMC continues to implement cost reductions on its current
products and expand its selling and marketing efforts in the United States and
abroad and continuously endeavors to expand its activities in non-military
aspects of the electronics industry. GMC has traditionally emphasized the
integrity, reliability and performance of its products.
 
BACKLOG
 
GMC's backlog was approximately $13,886,000 at February 28, 1998 and $16,946,000
at February 28, 1997. Although the contemplated end-use for products ordered is
not always identifiable, Management estimates that approximately 38% and 35% of
GMC's backlog at February 28, 1998 and February 28, 1997, respectively, is
attributable to products ordered for direct or indirect use by the United States
Government.
 
GMC manufactures standard components and equipment for inventory and specialized
components, systems and equipment pursuant to orders from customers. Orders are
included in backlog upon the receipt by GMC of verbal or written purchase orders
with firm delivery dates. Approximately 86% and 87%, respectively, of the
backlog at February 28, 1998 and February 28, 1997 is scheduled for shipment
within 12 months of such dates. The amount of backlog expected to be shipped
over such periods represents only a portion of anticipated sales for such
periods. Most of the orders included in GMC's current backlog may be cancelled
by customers without cause or penalty, subject to payment for costs incurred and
normal profit thereon.

does not anticipate making any material capital expenditures for environmental
control facilities for the remainder of its current fiscal year or its
succeeding fiscal year.
 
PROPERTIES
 
GMC manufactures microwave components and equipment in an approximately 60,000
square foot building it constructed on approximately 9.5 acres of land in the
New Horizons Business Center in Amityville, New York. The building provides an
integrated plant for GMC's operations including executive offices and research
and manufacturing facilities.
 
Substantially all of the estimated cost of the acquisition, construction and
equipping of the Amityville building was financed through variable rate
industrial development revenue bonds issued by the Town of Babylon Industrial
Development Agency (New York). GMC is leasing the facility from the issuer of
the Bonds at a rental equal to the amounts due from time to time under the
Bonds. At the expiration of the lease term on October 1, 1999, GMC may buy the
facility for nominal consideration. The indebtedness with respect to the Bonds
is secured by a mortgage of the premises. See Note 8 to the February 28, 1998
Consolidated Financial Statements of GMC included herein for additional
information concerning the Bonds.
 
GMC conducts its Israeli operations from an approximately 12,000 square foot
plant in the Talpiot Industrial Zone of Jerusalem. See Note 8 to February 28,
1998 Consolidated Financial Statements included herein for additional
information concerning the Talpiot facility. General Microcircuits Corporation
conducts its operations from an approximately 8,000 square foot leased facility
in Billerica, Massachusetts.

 GMC MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATIONS
 
The following discussion should be read in conjunction with the historical
financial statements of GMC, related notes and other financial information
included elsewhere in this Proxy Statement/Prospectus.
 
RESULTS OF OPERATIONS
 
SIX MONTHS ENDED AUGUST 29, 1998 COMPARED WITH THE SIX MONTHS ENDED AUGUST 30,
1997
 
During the first half of fiscal 1999, net sales were $11,835,926 compared with
$10,474,928 for the first half of fiscal 1998, representing a 13.0% increase.
Net earnings were $797,967 or $.66 basic net earnings per share and $.64 diluted
net earnings per share for the current period, as compared to net earnings of
$485,357 or $.40 basic and diluted net earnings per share from continuing
operations for the prior six month period. Net earnings for the first half of
fiscal 1998 were $1,438,168 or $1.19 basic net earnings per share and $1.18
diluted net earnings per share, which included net earnings from discontinued
operations of $952,811, or $.79 per basic share and $.78 per diluted share.
 
Sales increased primarily in the Amityville facility with significant earnings
improvement at both the Amityville and Billerica, Massachusetts facilities.
 
Cost of sales, as a percentage of sales, decreased to 62.1% in the first half of
fiscal 1999, compared to 65.2% in the first half of fiscal 1998, as a result of
a better product mix and continued improvements in processes and controls.
 
During the first half of fiscal 1999, selling expenses decreased as a percentage
of sales to 10.3% from 12.1% in the prior year principally due to lower
commissions and royalties payable related to the customer mix in the first half
of fiscal 1999. Interest expense decreased due to reduced borrowings. Investment
income increased because of increased levels of cash outstanding.
 
The provision for income taxes for the six months ended August 29, 1998,
reflects an estimated annual effective tax rate of approximately 32.9%. This
rate is less than the federal statutory rate of 34% principally due to a lower
tax rate on the income generated by GMC's Israeli subsidiary offset partially by
the provision for state income taxes.
 
During the first half of fiscal 1999, sales orders booked were $14.8 million and
the backlog was $16.9 million compared with $8.2 million and $14.7 million,
respectively, for the first half of fiscal 1998.
 
FISCAL 1998 COMPARED TO FISCAL 1997
 
In fiscal 1998, GMC had net earnings from continuing operations of $1,917,390 or
$1.59 basic and $1.56 diluted net earnings per share, as well as a net gain of
$952,811 from disposal of Math Associates, Inc., resulting in net earnings of
$2,870,201 or $2.38 basic net earnings per share and $2.34 diluted net earnings
per share. In fiscal 1997, GMC had net earnings of $201,730 or $.17 basic and
diluted net earnings per share from continuing operations and a net loss of
$3,085,736 or $2.56 basic and diluted net loss per share, after a loss of
$3,287,466 from discontinued operations. In fiscal 1996, GMC had a net loss from
continuing operations of $1,142,126 or $.95 basic and diluted net earnings per
share, and a net loss of $1,776,791 or $1.48 basic and diluted net earnings per
share, after a loss of $634,665 from discontinued operations.
 
                                       73
<PAGE>   83
 
The current year sales from continuing operations of $21,317,582 increased by
6.3% over the prior year. Sales of microwave components, hybrid microcircuits
and power measuring instruments all increased in fiscal 1998 as compared to
fiscal 1997. Fiscal 1997 sales ($20,060,888) had increased 15.1% over the fiscal
1996 sales level ($17,427,610) because of increased production levels and
shipments to a significant customer.
 
Fiscal 1998's operating earnings from continuing operations improved
dramatically (311%) in comparison to fiscal 1997 primarily due to gross profit
margins increasing to 36.3% in fiscal 1998 in comparison to 31.6% in the prior
year on increased sales. This improvement resulted from manufacturing
efficiencies, successful customer sponsored development activities and
reductions of overhead expenditures relative to production labor at the
Amityville, New York facility, as well as production efficiencies at the
Billerica, Massachusetts facility. Fiscal 1997's operating earnings from
continuing operations improved substantially in comparison to fiscal 1996
primarily due to increased gross profit margins, increased sales and reductions
in GMC sponsored research and development expenses. Fiscal 1996's operating
losses from continuing operations resulted principally from technical problems
which delayed shipments, increased production costs on a development program for
hybrid microcircuits products, inventory valuation reserves, as well as
increased selling expenses. In fiscal 1996, GMC recorded valuation reserves and
write offs related to the disposal of obsolete inventory of approximately
$440,000 and incurred one-time severance expenses aggregating $158,000.
Operating losses from discontinued operations in fiscal 1997 and fiscal 1996
resulted from additional inventory valuation reserves, low gross profit margins
and cost overruns on a fiber optic development program.
 
In February 1997, GMC decided to concentrate on its core businesses and adopted
a plan to exit the fiber optics business, which was operated by its Math
Associates, Inc. subsidiary (see Note 2 to GMC'S Consolidated Financial
Statements). Accordingly, unless otherwise indicated, all of the information
herein has been reclassified to present the assets, liabilities and results of
operations of the fiber optics business as a discontinued operation. On
September 24, 1997, a sale of certain of the assets of Math Associates, Inc. was
completed, which resulted in a gain from discontinued operations of $952,811 as
recorded in the consolidated financial statements for the year ended February
28, 1998. This gain relates principally to the proceeds from the sale of assets
and the reversal of estimated costs of liquidation which will no longer be
incurred as a result of the sale, and a provision for operating losses during
the phase out period that did not materialize.
 
New orders booked during the current year from continuing operations were
approximately $18.3 million compared to approximately $26.2 million last year.
The backlog of orders at February 28, 1998 was $13.9 million compared to $16.9
million at February 28, 1997. In the opinion of management, the strong
performance exhibited by GMC during fiscal 1998 is the result of its focused
effort to bring GMC back to growth and profitability. Although new orders booked
during fiscal 1998 did not achieve the levels of the prior year, GMC does not
believe that such reduction in orders in fiscal 1998 will have a material
adverse impact on its sales development in fiscal 1999. In fiscal 1996, orders
booked from continuing operations were $19.4 million and the backlog was $10.9
million at the year end.
 
General and administrative expenses, as a percentage of sales, were relatively
consistent in fiscal 1998 and 1997. Selling expenses as a percentage of sales
decreased in fiscal 1998 compared to 1997 as part of planned cost control
efforts. In fiscal 1997, while both selling and general and administrative
expenses increased, when compared to the prior year, they
 
                                       74
<PAGE>   84
 
both decreased as a percentage of sales due to budget and cost control efforts.
Although GMC sponsored research and development expenditures were reduced in
fiscal 1998 to $296,000 in comparison to $496,000 in fiscal 1997 and $1,094,000
in fiscal 1996, customer-sponsored research and development projects aggregated
$1,075,000 in fiscal 1998, as compared to $350,000 in fiscal 1997 and $625,000
in fiscal 1996. Research and development expenditures were significantly reduced
in fiscal 1997 in comparison to fiscal 1996 as the Israeli operation moved from
development efforts to increased production.
 
Interest expense decreased in fiscal 1998 as compared to fiscal 1997 as a result
of repayments of both short and long-term borrowings. Interest expense increased
in fiscal 1997 as compared to fiscal 1996 as a result of increased short term
borrowings at the Israeli operation. Dividend and interest income were
significantly higher in fiscal 1998 compared to the prior year as a result of
increased cash flow with resulting average higher investment balances.
 
The fiscal 1998 tax benefit results principally from the impact of previously
unrecognized tax benefits, generated primarily from the net loss on disposal of
Math Associates, Inc., net of state and foreign taxes of approximately $76,000.
In fiscal 1997, GMC recorded a tax provision related to continuing operations of
$40,000, as compared to a tax benefit of $222,000 for fiscal 1996. The fiscal
1997 tax provision principally represents taxes on the earnings of GMC's Israeli
operations. The fiscal 1996 tax benefit resulted primarily from a tax loss
carryback claim to recover Federal taxes paid for a three-year period and the
reduction of net deferred tax liabilities.
 
During the periods covered by this discussion, inflation did not have any
significant effect on GMC's business.
 
FISCAL 1997 COMPARED TO FISCAL 1996
 
In fiscal 1997, GMC had net earnings from continuing operations of $201,730 or
$.17 per share, a net loss of $3,287,466 from discontinued operations resulting
in a net loss after discontinued operations of $3,085,736 or $2.56 per share. In
fiscal 1996, GMC had a net loss of $1,142,126 or $.95 per share from continuing
operations and a net loss after discontinued operations of $1,776,791 or $1.48
per share. In fiscal 1995, GMC had net earnings from continuing operations of
$466,960 or $.38 per share, and a net profit after discontinued operations of
$174,676 or $.14 per share.
 
In February 1997, GMC decided to concentrate on its core businesses and adopted
a plan to exit the fiber optics business, which was operated by its Math
Associates subsidiary. (See Note 2 to Consolidated Financial Statements).
Accordingly, unless otherwise indicated, all of the information herein has been
reclassified to present the assets, liabilities and results of operations of the
discontinued fiber optics business as a discontinued operation. The loss from
discontinued operations includes a loss from operations for fiscal year 1997 of
approximately $627,000, as well as an estimated loss on disposal (including
management's best estimates of recoverability of assets and estimated loss
during the phase-out period) of approximately $2,660,000.
 
The current year sales from continuing operations of $20,060,888 increased by
$2,633,278 from the prior year, and was slightly higher than sales of two years
ago ($19,069,364). Sales of microwave components and hybrid microcircuits
increased in fiscal 1997 as compared to fiscal 1996, because of increased
production levels and shipments to a significant customer.
 
                                       75
<PAGE>   85
 
Fiscal 1997's operating earnings from continuing operations improved
substantially in comparison to fiscal 1996 primarily due to increased gross
profit margins, increased sales and reductions in research and development
expenses. Operating losses from discontinued operations in fiscal 1997 resulted
from additional inventory valuation reserves, low gross profit margins and cost
overruns on a fiber optic development program. Fiscal 1996's operating losses
from continuing operations resulted principally from technical problems which
delayed shipments, increased production costs on a development program for
hybrid microcircuits products, inventory valuation reserves, as well as
increased selling expenses. In fiscal 1996, GMC recorded valuation reserves and
write offs related to the disposal of obsolete inventory of approximately
$440,000 and incurred one-time severance expenses aggregating $158,000. The loss
from operations of the discontinued business increased due to technical
problems, increased production costs on a fiber optic development program and
increased inventory valuation reserves.
 
Management's efforts to increase shipments , implement more effective operations
and reduce cost of sales, resulted in significantly improved fiscal 1997 fourth
quarter profitability from continuing operations of approximately $597,000 as
compared to approximately $274,000 in fiscal 1996. Management will continue to
focus on further process and quality effectiveness for gross profit margin
improvement in fiscal 1998. As part of its efforts to improve earnings in fiscal
1998, management decided to focus on GMC's core businesses and discontinue the
lower profit margin fiber-optic systems and components business.
 
New orders booked during the current year from continuing operations were
approximately $26.2 million compared to approximately $19.4 million last year.
The backlog of orders at February 28, 1997 was $16.9 million compared to $10.9
million at February 29, 1996. In fiscal 1995, orders booked from continuing
operations were $20.0 million and the backlog was $9.2 million at the year end.
 
Cost of sales during fiscal 1997, as a percentage of sales, was 68.4% compared
with 71.4% in 1996 and 67.6% in 1995. In fiscal 1997, the cost of sales
percentage decreased primarily due to resolution of technical problems and
production difficulties experienced in 1996 on two large production programs in
microwave components and hybrid microcircuits, as well as improved efficiencies.
In fiscal 1996, the cost of sales percentage increased primarily due to
technical problems and cost overruns on a certain development program and
increased inventory valuation reserves, as well as non-recurring severance
expenses.
 
In fiscal 1997, while both selling and general and administrative expenses
increased, when compared to the prior year, they both decreased as a percentage
of sales due to budget and cost control efforts. Research and development
expenditures were significantly reduced in 1997 in comparison to 1996 as the
Israeli operation moved from development efforts to increased production. In
fiscal 1996, selling and general and administrative expenses increased, when
compared to 1995, due primarily to increased selling efforts at the Amityville
microwave operations. Research and development expenses increased from the prior
year because of increases at General Microwave Israel, notwithstanding decreases
in the U.S. divisions.
 
Interest expense increased in fiscal 1997 as compared to 1996 as a result of
increased short term borrowings at the Israeli operation. Although borrowing and
interest thereon increased in fiscal 1996, interest expense decreased compared
to fiscal 1995's interest expense which included interest due on taxes paid
pursuant to a tax audit. Dividend and interest income were lower in fiscal 1996
compared to the prior year as a result of a reduction in average investment
balances and lower interest rates during the year.
 
                                       76
<PAGE>   86
 
In fiscal 1997 GMC recorded a tax provision related to continuing operations of
$40,000, as compared to a tax benefit of $222,000 for fiscal 1996 and a tax
benefit of $266,000 for fiscal 1995. The fiscal 1997 tax provision principally
represents taxes on the earnings of GMC's Israeli operations. The fiscal 1996
tax benefit resulted primarily from a tax loss carryback claim to recover
Federal taxes paid for a three-year period and the reduction of net deferred tax
liabilities. The fiscal 1995 tax benefit resulted primarily from the Israeli
government's approval to utilize a corporate tax rate of 10% in Israel instead
of the statutory 38% as well as the reversal of excess liabilities no longer
determined to be required given the completion of tax audits of several years in
fiscal 1995.
 
During the periods covered by this discussion, inflation did not have any
significant effect on GMC's business.
 
LIQUIDITY AND CAPITAL RESOURCES
 
At August 29, 1998, GMC's ratio of current assets to current liabilities was 3.4
to 1 compared to 3.2 to 1 at February 28, 1998.
 
During the first half of fiscal 1999, cash flows from continuing operations
increased to approximately $1,964,000 as compared to the comparable period last
year of approximately $957,000, primarily due to increased profitability from
operations and reductions in accounts receivable during the six month period. A
portion of cash flows during the first half of fiscal 1999 were utilized to
purchase equipment for approximately $436,000 and repay long and short term
borrowings totaling approximately $252,000. GMC expects to spend up to $350,000
during the remainder of the year for capital equipment.
 
The agreements relating to the GMC's 7-Day Demand Industrial Development Revenue
Bonds contain several restrictive covenants. GMC must, among other things,
maintain profitable operations, a minimum ratio of current assets to current
liabilities, a minimum level of tangible net worth, as defined, and must not
exceed a specified debt to equity ratio. The tangible net worth covenant limits
the ability of GMC to pay cash dividends. As a result of such covenant, there is
approximately $2,507,000 of unrestricted funds available for the payment of cash
dividends as of August 29, 1998. Management of GMC anticipates using such funds
to enhance future operations and does not anticipate cash dividends in the
immediately foreseeable future. In addition, as of August 1998, GMC is no longer
required to make monthly sinking fund payments towards its annual bond payment.
This amount is reflected as restricted cash on the accompanying consolidated
balance sheet as of February 28, 1998.
 
GMC believes that its present resources, including available credit, are
sufficient to meet its needs for the foreseeable future.
 
On August 21, 1998, GMC entered into an agreement and plan of merger dated as of
August 21, 1998 that contemplates the merger of GMC into a wholly-owned
subsidiary of Herley for $18.00 per outstanding share of stock of GMC in cash
and a three year Warrant to purchase one share of common stock of Herley
exercisable at $14.40 per share through January 11, 1999, and thereafter at
$15.60 per share until expiration. Thirty percent of General Microwave
Corporation's shareholders have signed irrevocable proxies agreeing to the
merger of the two companies. The transaction is subject to the approval of the
stockholders of GMC and customary closing conditions.

YEAR 2000 CONVERSION
 
GMC has initiated a comprehensive Year 2000 program to insure there will be no
adverse business effects by Year 2000 issues. GMC has instituted extensive
internal review and testing procedures on an ongoing basis to guarantee that all
systems are compliant. At the same time it is contacting its vendors and service
providers and requiring written Year 2000 compliance. Based on GMC's ongoing
evaluation, management currently believes that the costs to achieve year 2000
compliance will not be material to GMC's financial position or results of
operations. GMC expects to complete its investigation, remediation and
contingency planning activities for all mission critical systems and areas by
June 30, 1999. At this time, GMC does not believe that it has any internal
mission critical Year 2000 issues that it cannot remedy. General Microwave
products are free from components that are time and date dependent and therefore
will not be affected by the Year 2000. Despite its efforts to survey its
customers, suppliers and service providers, GMC cannot be certain as to the
actual Year 2000 readiness of these third parties or the impact that any non-
compliance on their part may have on GMC's business, results of operations or
financial condition.

(1) Mr. Levine became an executive officer of GMC during fiscal year 1996.
 
(2) Mr. DeBrecht became an executive officer of GMC during fiscal year 1997.
 
(3) The options reported as granted in fiscal year 1997 were previously granted
    options which were repriced as part of GMC-wide option repricing to reflect
    the then current market value of GMC's common stock at that time. The
    options reported as granted to Mr. DeBrecht in that year (the only ones on
    the table originally granted in that year) were granted and then repriced,
    thus 10,000 shares are reported as securities underlying options granted to
    him in that year although after giving effect to the repricing, he only had
    an option to purchase 5,000 shares of GMC's common stock.
 
STOCK OPTION GRANTS AND EXERCISES
 
GMC has in effect an employee stock option plan. It does not have any restricted
stock or stock appreciation rights plans. During the last fiscal year, no
options were granted to or exercised by any of the named executive officers. The
following table contains information concerning the 1998 fiscal year end value
of unexercised options held by the named executive officers.

                      DESCRIPTION OF HERLEY CAPITAL STOCK
 
CAPITAL STOCK
 
Herley's authorized capital stock consists of 20,000,000 shares of Herley common
stock, $.10 par value per share.
 
COMMON STOCK
 
GENERAL.  Herley has 20,000,000 authorized shares of Herley common stock,
5,295,540 of which were issued and outstanding on November 17, 1998. All shares
of Herley common stock currently outstanding are validly issued, fully paid and
non-assessable, and all shares which are the subject of this Proxy
Statement/Prospectus, when issued and paid for upon the exercise of the
Warrants, will be validly issued, fully paid and non-assessable.
 
VOTING RIGHTS.  Each share of Herley common stock entitles the holder thereof to
one vote, either in person or by proxy, at meetings of the stockholders.
Herley's Board of Directors consists of three classes, each of which serves for
a term of three years. At each annual meeting of the stockholders the directors
in only one class will be elected. The holders are not permitted to vote their
shares cumulatively. Accordingly, the holders of more than 50% of the
outstanding shares of Herley common stock can elect all of the directors of
Herley standing for election at a stockholders' meeting.
 
DIVIDEND POLICY.  All shares of Herley common stock are entitled to participate
ratably in dividends when and as declared by Herley's Board of Directors out of
the funds legally available therefor. Any such dividends may be paid in cash,
property or additional shares of Herley common stock. Herley has not paid any
cash dividends in the past two fiscal years or the current fiscal year and does
not anticipate that cash dividends will be declared in the foreseeable future.
While Herley declared a four-for-three stock split effected as a stock dividend
effective September 30, 1997, payment of future dividends is subject to the
discretion of Herley's Board of Directors and will depend upon, among other
things, future earnings, the operating and financial condition of Herley, its
capital requirements, general business conditions and other pertinent facts.
Therefore there can be no assurance that any dividends on the Herley common
stock will be paid in the future. See "Dividend Policy."
 
MISCELLANEOUS RIGHTS AND PROVISIONS.  Holders of Herley common stock have no
preemptive or other subscription rights, conversion rights, redemption or
sinking fund provisions. In the event of the liquidation or dissolution, whether
voluntary or involuntary, of Herley, each share of common stock is entitled to
share ratably in any assets available for distribution to holders of the equity
of Herley after satisfaction of all liabilities.
 
SHARES ELIGIBLE FOR FUTURE SALE.  Herley has 5,295,540 shares of Herley common
stock outstanding, of which 4,612,327 are freely tradeable without restriction
or further registration under the Securities Act, except for any shares
purchased by an "affiliate" of Herley (in general, a person who has a control
relationship with Herley), which will be subject to the limitations of Rule 144
adopted under the Securities Act. The remaining shares are deemed to be
"restricted securities," as that term is defined under Rule 144.
 
Upon completion of the Merger, Herley will have issued approximately 970,000
Warrants to purchase shares of Herley common stock, assuming that no GMC
shareholders exercise dissenters' rights. In addition, Herley has outstanding
1,265,000 warrants that will be exercisable for 1,265,000 newly issued shares of
Herley common stock Upon exercise of those warrants to purchase, all of these
shares of Herley common stock will also be freely tradeable without restriction
or future registration under the Securities Act.
 
                                       86
<PAGE>   96
 
In general, under Rule 144 as currently in effect, subject to the satisfaction
of certain other conditions, a person, who owns restricted securities for at
least one year is entitled to sell, within any three-month period, a number of
such securities that does not exceed the greater of 1% of the total number of
securities outstanding of the same class or the average weekly trading volume of
the securities on all exchanges and/or reported through the automated quotation
system of a registered securities association during the four calendar weeks
preceding the date on which notice of the sale is filed with the Commission.
Sales under Rule'144 are also subject to certain manner of sale provisions,
notice requirements and the availability of current public information about the
issue. In addition, an affiliate of the issuer is subject to such volume
limitations when selling both restricted and unrestricted securities. A person
who has not been an affiliate of Herley for at least the three months
immediately preceding the sale and who has beneficially owned the securities for
at least two years, however, is entitled to sell such securities under Rule 144
without regard to any of the limitations described above. Of the 683,213 shares
of Herley common stock that constitute restricted securities, 668,045 shares
have been held for more than one year.
 
No predictions can be made as to the effect, if any, that sales of shares of
Herley common stock under Rule 144 or otherwise or the availability of shares
for sale will have on the market, if any, prevailing from time to time. Sales of
a substantial number of shares of the Herley common stock pursuant to Rule 144
or otherwise may adversely affect the market price of the Herley common stock or
the Warrants.
 
DESCRIPTION OF WARRANTS
 
The following is a brief summary of certain provisions of the Warrants and of
Herley's currently outstanding common stock purchase warrants. Such summary does
not purport to be complete and is qualified in all respects by reference to the
Warrant Agreement (the "Warrant Agreement") among Herley, the Selling
Stockholders and American Stock Transfer & Trust Company (the "Warrant Agent").
A copy of the Warrant Agreement has been filed as an exhibit to the Registration
Statement. The Warrants to be issued upon consummation of the Merger are a
different class than the common stock purchase warrants which are currently
listed and traded on the Nasdaq National Market System under the symbol HRLYW.
The terms of the Warrants and the publicly-traded warrants are identical except
that the Warrants expire thirty-six months from their date of issuance and the
publicly-traded Warrants expire in January 1999, which is twenty-five months
from their date of issuance.
 
EXERCISE PRICE AND TERMS.  Each Warrant entitles the registered holder thereof
to purchase one share of Herley common stock at an exercise price of $ 14.40 per
share prior to January 11, 1999 and $15.60 per share thereafter, subject to
adjustment in accordance with the anti-dilution and other provisions referred to
below. The holder of any Warrant may exercise such Warrant by surrendering the
certificate representing the Warrant to the Warrant Agent, with the subscription
form thereon properly completed and executed, together with payment of the
exercise price. The Warrants may be exercised at any time in whole or in part at
the exercise price then in effect until expiration of the Warrants. The Warrants
expire thirty-six months from their date of issuance. No fractional shares will
be issued upon the exercise of the Warrants.
 
The exercise price of the Warrants to be issued in the Merger is the same as the
exercise price of certain of Herley's outstanding warrants and bears no
relationship to any objective
 
                                       87
<PAGE>   97
 
criteria of future value. Accordingly, such exercise price should in no event be
regarded as an indication of any future trading price.
 
ADJUSTMENTS.  The exercise price and the number of shares of Herley common stock
purchasable upon the exercise of the Warrants are subject to adjustment upon the
occurrence of certain events, including stock dividends, stock splits,
combinations or reclassifications of the Herley common stock, or sale by Herley
of shares of its Herley common stock or other securities convertible into Herley
common stock (exclusive of shares issued upon the exercise or conversion of
outstanding options, warrants and convertible securities) at a price below the
market price of the Herley common stock as defined in the Warrant Agreement.
Additionally, an adjustment would be made in the case of a reclassification or
exchange of Herley common stock, consolidation or merger of Herley with or into
another corporation (other than a consolidation or merger in which Herley is the
continuing corporation) or sale of all or substantially all of the assets of
Herley in order to enable Warrant holders to acquire the kind and number of
shares of stock or other securities or property receivable in such event by a
holder of the number of shares of Herley common stock that might otherwise have
been purchased upon the exercise of the Warrant.
 
TRANSFER, EXCHANGE AND EXERCISE.  The Warrants are in registered form and may be
presented to the Warrant Agent for transfer, exchange or exercise at any time on
or prior to their expiration date thirty-six months from the date of issuance,
at which time the Warrants become wholly void and of no value. If a market for
the Warrants develops, the holder may sell the Warrants instead of exercising
them. There can be no assurance, however, that a market for the Warrants will
develop or continue.
 
WARRANT HOLDER NOT A STOCKHOLDER.  The Warrants do not confer upon holders any
voting, dividend or other rights as stockholders of Herley.
 
REDEMPTION OF WARRANTS.  Herley may redeem the Warrants, in whole or in part, at
any time after 21 months from their issuance at a price of $1.00 per share of
common stock by delivery of 30 days' written notice if the average last reported
sales price of the Herley common stock has not been less than $17.60 per share
for the fifteen consecutive trading days immediately prior to the notice date.
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION
 
Herley's Certificate of Incorporation and By-laws contain certain provisions,
including a prohibition against removal of directors other than for cause, that
are intended to enhance the continuity and stability of management by making it
more difficult for stockholders to remove or change the incumbent members of the
Board of Directors. The Certificate of Incorporation includes additional
provisions that are intended to discourage certain types of transactions that
involve an actual or threatened change of control of Herley. The Certificate of
Incorporation provides for a Board of Directors classified into three groups,
each of which group's term of office expires in successive years. The
Certificate of Incorporation also provides that written notice of the intent to
make a nomination at a meeting of stockholders must be received by Herley at
least 90 days in advance of such meeting.
 
The Certificate of Incorporation further requires that stockholders entitled to
vote 80% of the outstanding shares of the Herley common stock approve certain
business combinations with interested stockholders. These business combinations
include mergers, sales of assets in excess of $5,000,000, issuance of certain
securities having an aggregate fair market value
 
                                       88
<PAGE>   98
 
of $5,000,000 or more, adoption of any plan of liquidation or dissolution and
any reclassification of securities unless approved by the disinterested members
of the Board of Directors the transaction complies with certain provisions
relating to the fair valuation and consummation of such business combination.
 
The Certificate of Incorporation further provides that stockholders of Herley
are not permitted to call a special meeting of stockholders or to require the
Board of Directors to call such a special meeting. Thus, a stockholder could not
force stockholder consideration of a proposal over the opposition of the Board
of Directors by calling a special meeting of the stockholders.
 
The foregoing provisions may adversely affect the ability of potential acquires
to obtain control of Herley in any transaction that is not approved by Herley's
Board of Directors. The use of these provisions as anti-takeover devices might
preclude stockholders from taking advantage of certain situations that they
believe could be favorable to their interests.
 
                          COMPARISON OF CAPITAL STOCK
 
THE FOLLOWING DISCUSSION SUMMARIZES THE MATERIAL DIFFERENCES BETWEEN THE RIGHTS
OF HOLDERS OF HERLEY COMMON STOCK AND HOLDERS OF GMC COMMON STOCK. SINCE HERLEY
IS ORGANIZED UNDER AND SUBJECT TO THE LAWS OF DELAWARE AND GMC IS ORGANIZED
UNDER THE LAWS OF NEW YORK, CERTAIN OF THESE DIFFERENCES ARISE BY STATUTE WHILE
OTHERS ARISE FROM VARIOUS PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND
BY-LAWS OF EACH OF HERLEY AND GMC. THIS SUMMARY DOES NOT PURPORT TO BE COMPLETE
AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE CERTIFICATE OF
INCORPORATION AND BY-LAWS OF HERLEY AND GMC.
 
After consummation of the Merger, the holders of GMC common stock who receive
Warrants to purchase Herley common stock under the terms of the Agreement will,
upon exercise of such Warrants, become stockholders of Herley. As shareholders
of GMC, their rights are presently governed by New York law and the GMC
Certificate of Incorporation, as amended (the "GMC Certificate"), and By-laws
(the "GMC By-laws"). As stockholders of Herley, their rights will be governed by
Delaware law and by the Herley Certificate and Herley By-laws (the "Herley
By-laws").
 
SPECIAL MEETING OF STOCKHOLDERS
 
The Herley By-laws provide that special meetings of stockholders may be called
only by the Board of Directors. The GMC By-laws provide that special meetings of
stockholders may be called by GMC's president or any vice-president and must be
called by the president, vice-president or secretary at the request of a
majority of the Board. Neither corporation provides for the ability of
stockholders to demand a special meeting.
 
ACTION BY CONSENT OF STOCKHOLDERS
 
Under Delaware law, unless the certificate of incorporation provides otherwise,
any action to be taken by stockholders may be taken without a meeting, without
prior notice, and without a vote, if the stockholders having the number of votes
that would be necessary to take such action at a meeting at which all
stockholders were present and voted consent to the action in writing. The NY
Corporation Law, however, provides that any action required or permitted to be
taken by its stockholders cannot be effected other than by unanimous written
consent unless the certificate of incorporation otherwise provides. The GMC
Certificate does not provide for shareholder action by consent.
 
                                       89
<PAGE>   99
 
CUMULATIVE VOTING
 
Under Delaware law, a corporation may provide in its certificate of
incorporation for cumulative voting by stockholders in elections of directors
(i.e., each stockholder casts as many votes for directors as he has shares of
stock multiplied by the number of directors to be elected). The GMC Certificate
does not provide for cumulative voting. The Herley Certificate does not provide
for cumulative voting, so holders of Herley common stock after the Merger will
not have cumulative voting rights.
 
CLASSIFICATION OF THE BOARD OF DIRECTORS
 
The Herley Certificate provides for the classification of its Board of Directors
into three classes. The Herley By-laws provide that the number of directors
shall not be less than three nor more than twelve. As a result of such
classification, a person wishing to propose alternative nominees for election to
the Herley Board of Directors would only be able to propose nominees for
one-third of the Board. The GMC Certificate does not provide for classes of
directors. The GMC By-laws provide that the number of directors shall be nine.
 
REMOVAL OF DIRECTORS
 
As Herley has a classified board, Section 141 of the Delaware General
Corporation Law provides that shareholders may effect removal of a director only
for cause. Section 706 of the NYBCL provides that a director may be removed for
cause by a majority vote of the shares entitled to vote provided, that if
stockholders are entitled to cumulative voting, no director can be removed
without cause if the votes cast against removal of such director would be
sufficient to elect him or her if then cumulatively voted at an election of the
entire board.
 
EXCULPATION OF DIRECTORS
 
Each of the Herley Certificate and the GMC Certificate provide that no director
shall be personally liable to Herley and GMC, respectively, or their respective
stockholders for monetary damages for breaches of fiduciary duty except where
such exculpation is expressly prohibited by law.
 
INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS
 
The Herley Certificate authorizes Herley to provide indemnification to its
agents to the maximum extent legally permissible. Herley's By-laws provide for
indemnification of any person made a party to any action, suit or proceeding by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation. Herley has entered into indemnification agreements with each of
its directors and executive officers. GMC's By-laws provide for indemnification
to its directors and executive officers to the maximum extent legally
permissible and that the corporation has the power to provide indemnification
for its employees and agents.
 
                                 LEGAL MATTERS
 
The validity of the Warrants issuable pursuant to the Merger and the Herley
common stock issuable upon exercise of the Warrants will be passed on by Blau,
Kramer, Wactlar & Lieberman, P.C., Jericho, New York. Zissu Gumbinger & Stolzar
LLP, New York, New York is acting as counsel for GMC in connection with certain
legal matters relating to the Merger and the transaction contemplated thereby.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
Herley Industries, Inc.:
 
We have audited the accompanying consolidated balance sheets of Herley
Industries, Inc. and Subsidiaries as of August 2, 1998, and August 3, 1997, and
the related consolidated statements of income, shareholders' equity and cash
flows for the 52 weeks ended August 2, 1998, the 53 weeks ended August 3, 1997,
and the 52 weeks ended July 28, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Herley Industries,
Inc. and Subsidiaries as of August 2, 1998, and August 3, 1997, and the
consolidated results of their operations and cash flows for the 52 weeks ended
August 2, 1998, the 53 weeks ended August 3, 1997, and the 52 weeks ended July
28, 1996 in conformity with generally accepted accounting principles.

                    HERLEY INDUSTRIES, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
1.  NATURE OF OPERATIONS
 
The Company, a Delaware corporation, is engaged in the design, development,
manufacture and sale of flight instrumentation components and systems, and
microwave products, primarily to aerospace companies, the U.S. government, and
several foreign governments. The Company's main products include a variety of
transponders which are used to enhance radar signals to accurately track the
flight of space launch vehicles and aircraft, as well as microwave devices and
command and control systems.
 
2.  FISCAL YEAR
 
The Company's fiscal year ends on the Sunday closest to July 31. Normally each
fiscal year consists of 52 weeks, but every five or six years the fiscal year
will consist of 53 weeks. Fiscal years 1998 and 1996 consisted of 52 weeks, and
fiscal year 1997 consisted of 53 weeks.
 
3.  BASIS OF FINANCIAL STATEMENT PRESENTATION
 
The consolidated financial statements include the accounts of Herley Industries,
Inc. and its subsidiaries, all of which are wholly-owned. All significant
inter-company accounts and transactions have been eliminated in consolidation.
The presentation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities as of the date of the financial statements as
well as revenues and expenses during the period. Actual results could differ
from those estimates.
 
4.  CASH AND CASH EQUIVALENTS
 
The Company considers all liquid investments with an original maturity of three
months or less at the date of acquisition to be cash equivalents. Short-term
investments are recorded at the amortized cost plus accrued interest which
approximates market value. The Company limits its credit risk to an acceptable
level by evaluating the financial strength of institutions at which significant
investments are made and based upon credit ratings.
 
5.  CONCENTRATION OF CREDIT RISK
 
Financial instruments which potentially subject the Company to credit risk
consist primarily of trade accounts receivable. Accounts receivable are
principally from the U.S. Government, major U.S. Government contractors, several
foreign governments, and domestic customers in the aerospace and defense
industries. Credit is extended based on an evaluation of the customer's
financial condition and generally collateral is not required. In many cases
irrevocable letters of credit accompanied by advanced payments are received from
foreign customers, and progress payments are received from domestic customers.
The Company performs periodic credit evaluations of its customers and maintains
reserves for potential credit losses.
 
6.  INVENTORIES
 
Inventories, other than inventory costs relating to long-term contracts and
programs, are stated at lower of cost (principally first-in, first-out) or
market. Inventory costs relating to long-term contracts and programs are stated
at the actual production costs, including
 
                                      F-10

                    HERLEY INDUSTRIES, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
factory overhead, reduced by amounts identified with revenue recognized on units
delivered or progress completed.
 
Inventory costs relating to long-term contracts and programs are reduced by any
amounts in excess of estimated realizable value. The costs attributed to units
delivered under long-term contracts and programs are based on the average costs
of all units produced.
 
7.  PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment are stated at cost. Depreciation and amortization
are provided principally by the straight-line method over the estimated useful
lives of the related assets. Gains and losses arising from the sale or
disposition of property, plant and equipment are recorded in income.
 
8.  INTANGIBLES
 
Intangibles are comprised of customer lists, installed products base, drawings,
patents, licenses, certain government qualifications and technology and goodwill
in connection with the acquisitions of Metraplex Corporation in 1997, and Vega
Precision Laboratories, Inc. in 1993. Intangibles are being amortized over
twenty years.
 
The carrying amount of intangibles is evaluated on a recurring basis. Current
and future Profitability as well as current and future undiscounted cash flows
of the acquired businesses are primary indicators of recoverability. For the
three fiscal years ended August 2, 1998, there were no adjustments to the
carrying amount of the cost in excess of net assets acquired resulting from
these evaluations.
 
9.  MARKETABLE SECURITIES
 
The Company accounts for its investments in marketable securities in accordance
with Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." Management determines the
appropriate classification of debt securities at the time of purchase and
reevaluates such designation as of each balance sheet date. Debt securities are
classified as held-to-maturity when the Company has the positive intent and
ability to hold the securities to maturity. Marketable equity securities and
debt securities not classified as held-to-maturity are classified as
available-for-sale. Available-for-sale securities are carried at fair value,
with the unrealized gains and losses, net of tax, reported as a separate
component of shareholders' equity. Realized gains and losses and declines in
value judged to be other-than-temporary are included in other income, net. The
cost of securities sold is based on the specific identification method. Interest
and dividends on securities are included in other income, net.
 
10.  OTHER INVESTMENTS
 
The Company is a limited partner in a nonmarketable limited partnership in which
it owns approximately a 10% interest. Beginning in 1997 other investments are
accounted for under the equity method. Previously, the cost method was utilized
as the amount was not significantly different from the equity method.
 
11.  REVENUE AND COST RECOGNITION
 
Under fixed-price contracts, revenue and related costs are recorded primarily as
deliveries are made. Certain costs under long-term, fixed-price contracts
(principally either directly or indirectly with the U.S. Government), which
include non-recurring billable engineering,
 
                                      F-11
<PAGE>   113
                    HERLEY INDUSTRIES, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
are deferred until these costs are contractually billable. Revenue under certain
long-term, fixed price contracts, principally command and control shelters, is
recognized using the percentage of completion method of accounting. Revenue
recognized on these contracts is based on estimated completion to date (the
total contract amount multiplied by percent of performance, based on total costs
incurred in relation to total estimated cost at completion). Prospective losses
on long-term contracts are based upon the anticipated excess of inventoriable
manufacturing costs over the selling price of the remaining units to be
delivered and are recorded when first reasonably determined. Actual losses could
differ from those estimated due to changes in the ultimate manufacturing costs
and contract terms.
 
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance. Selling, general and administrative costs
are charged to expense as incurred.
 
12.  INCOME TAXES
 
Income taxes are accounted for by the asset/liability approach in accordance
with Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes." Deferred taxes represent the expected future tax consequences when the
reported amounts of assets and liabilities are recovered or paid. They arise
from temporary differences between the financial reporting and tax bases of
assets and liabilities and are adjusted for changes in tax laws and tax rates
when those changes are enacted. The provision for income taxes represents the
total of income taxes paid or payable for the current year, plus the change in
deferred taxes during the year.
 
13.  STOCK-BASED COMPENSATION
 
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
compensation," encourages, but does not require companies to record compensation
cost for stock-based employee compensation plans at fair value. The Company has
chosen to continue to account for stock-based compensation using the intrinsic
value method prescribed in Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related Interpretations.
Accordingly, compensation cost for stock options is measured as the excess, if
any, of the quoted market price of the Company's stock at the date of the grant
over the amount an employee must pay to acquire the stock. Because the exercise
price of the Company's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.
 
14.  EARNINGS PER COMMON SHARE
 
In 1997, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), which replaced
APB No. 15 to conform earnings per share with international standards as well as
to simplify the complexity of the computation under APB No. 15. The previous
primary earnings per share ("EPS") calculation is replaced with a basic EPS
calculation. The basic EPS differs from the primary EPS calculation in that the
basic EPS does not include any potentially dilutive securities. Fully dilutive
EPS is replaced with diluted EPS and should be disclosed regardless of dilutive
impact to basic EPS. In accordance with SFAS 128, all earnings per share amounts
for all periods presented have been restated (reflective of a 4-for-3 stock
split on September 30, 1997).

15.  PRODUCT DEVELOPMENT
 
The Company's primary efforts are focused on engineering design and product
development activities rather than pure research. The cost of these development
activities, including employees' time and prototype development, net of amounts
paid by customers, was approximately $1,562,000, $1,828,000, and $1,453,000 in
fiscal 1998, 1997, and 1996, respectively.
 
16.  NEW ACCOUNTING STANDARDS
 
In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Segment Information", which is effective for fiscal years beginning after
December 15, 1997. SFAS No. 131 amends the requirements for public enterprises
to report financial and descriptive information about its reportable operating
segments. Operating segments, as defined in SFAS No. 131, are components of an
enterprise for which separate financial information is required to be reported
on the basis that is used internally for evaluating the segment performance. The
Company believes it operates in one business segment, and as this standard
relates entirely to disclosure, the adoption of this standard will not have a
material impact on the Company's financial statements.
 
NOTE B -- ACQUISITIONS
 
On August 4, 1997, the Company completed the acquisition of Metraplex
Corporation, a Maryland corporation for 313,139 (as adjusted) shares of common
stock of the Company, with a fair market value of $3,170,471, in exchange for
all of the issued and outstanding common stock of Metraplex. Metraplex is a
leading manufacturer of pulse code modulation and frequency modulation,
telemetry and data acquisition systems for severe environment applications. The
transaction has been accounted for by the purchase method. Accordingly, the
consolidated balance sheet includes the assets and liabilities of Metraplex at
August 2, 1998, and the consolidated statements of income include the results of
Metraplex operations from August 4, 1997. The acquisition resulted in excess of
cost over fair value of net assets acquired of $2,162,725 which is being
amortized over twenty years.
 
On the basis of a pro forma consolidation of the results of operations as if the
acquisition had taken place at the beginning of fiscal 1997, unaudited
consolidated net sales, net income, basic earnings per share, and diluted
earnings per share for the year ended August 3, 1997 would have been
approximately $36,589,333, $4,686,236, $1.07, and $.93, respectively. The pro
forma information includes adjustments for additional depreciation based on the
fair market value of the property and equipment acquired, and the amortization
of intangibles arising from the transaction. The pro forma financial information
is not necessarily indicative of the results of operations as they would have
been had the transaction been effected at the beginning of fiscal 1997.
 
In July 1995, the Company entered into an agreement effective as of the close of
business June 30, 1995, to acquire certain assets and the business (consisting
principally of inventories and trade receivables) of Stewart Warner Electronics
Corporation, a Delaware corporation. The transaction, which closed on July 28,
1995, provided for the payment of $250,000 in cash and the assumption of
approximately $915,000 in liabilities and has been accounted for by the purchase
method. The acquisition resulted in excess of fair value over cost of net assets
acquired of $1,460,500 which is being amortized over a three-year period.

NOTE E -- AVAILABLE-FOR-SALE SECURITIES
 
In September 1996, the Company liquidated all of its available-for-sale
securities for approximately $4,912,000 and used the proceeds to reduce its
long-term bank debt. A provision for unrealized losses of $121,550 is included
in the statement of operations for fiscal year 1996. The fair value of
available-for-sale securities at July 28, 1996 was $4,912,387.
 
NOTE F -- OTHER INVESTMENTS
 
In April 1996, the Company acquired a limited partnership interest in M.D. Sass
Re/ Enterprise-II, L.P., a Delaware limited partnership for $2,000,000. The
objective of the partnership is to achieve superior long-term capital
appreciation through investments consisting primarily of securities of companies
that are experiencing significant financial or business difficulties. In April
1997, the Company sold its investment and terminated its limited partnership
interest for $2,080,630 realizing a gain of $80,630.
 
In July 1994, the Company invested $1,000,000 for a limited partnership interest
in M.D. Sass Municipal Finance Partners-I, a Delaware limited partnership. The
objectives of the partnership are the preservation and protection of its capital
and the earning of income through the purchase of certificates or other
documentation that evidence liens for unpaid local taxes on parcels of real
property. At August 2, 1998 and August 3, 1997 the percentage of ownership was
approximately 10%. The Company's interest in the partnership may be transferred
to a substitute limited partner, upon written notice to the managing general
partners, only with the unanimous consent of both general partners at their sole
discretion.
 
In July 1998 the Company received a partial distribution of $592,824 from the
Partnership. As of August 2, 1998 the Company's limited partnership interest had
an estimated fair value of $849,324.

EMPLOYMENT AGREEMENTS
 
The Company has employment agreements with various executives and employees of
the Company, which, as amended, expire at various dates through October 31,
2002, subject to extension each January 1 for three years from that date. These
agreements provide for aggregate annual salaries for fiscal 1999 of $800,000.
Certain agreements provide for an annual cost of living adjustment based on the
consumer price index, and also provide for incentive compensation based on
pretax income of the Company in excess of 10% of the Company's stockholders'
equity for specific periods, as adjusted for stock issuances and repurchases.
Incentive compensation in the amount of $727,659, $665,352, and $446,750 was
expensed in fiscal years 1998, 1997, and 1996, respectively.

Certain agreements also provide that, in the event there is a change in control
of the Company, as defined, the executives have the option to terminate the
agreements and receive a lump-sum payment of approximately three times their
annual salary. As of August 2, 1998, the amount payable in the event of such
termination would be approximately $2,400,000.
 
One of the employment contracts provides for a consulting agreement commencing
at the end of the employment period which will be effective October 1, 1998, and
terminating December 31, 2010 at the annual rate of $100,000. Another one of the
employment contracts, as amended October 1, 1998, provides for a consulting
period commencing at the end of the period of active employment and continuing
for a period of five years at the annual rate of $100,000. Two officers of the
Company have severance agreements providing for a lump-sum payment of $430,000
through fiscal 1999, adjusted to $320,000 in fiscal 2000, $215,000 through
fiscal 2002,and $105,000 in fiscal 2003.
 
LITIGATION
 
In November 1996, the Company settled all claims in connection with two class
action complaints, related to the Company's acquisition of Carlton Industries,
Inc. and its subsidiary, Vega Precision Laboratories, Inc. for $450,000.
 
In August 1997, the Company settled all claims in connection with a class action
complaint filed in 1995 for $170,000. The claim related to the Company's
settlement of the Litton Action in the Essex Superior Court of Massachusetts
which alleged, inter alia, that there was insufficient disclosure by the Company
of its true potential exposure in that claim. In July 1996, the Company was
notified by the American Arbitration Association of the decision of the
arbitrators in an action commenced in March 1994 by the principal selling
shareholders of Carlton Industries, Inc. and its subsidiary, Vega Precision
Laboratories, Inc. According to the award, the Company was to pay to the
claimants the sum of $1,052,900, inclusive of interest. Correspondingly, the
claimants were to pay the Company the sum of $277,719, inclusive of interest.
The Company paid $775,181 to claimants, representing the difference between the
award to the claimants and the award to the Company, in August, 1996. The award
to the claimants was offset by $593,162 otherwise payable to one of the selling
shareholders.
 
The Company is also involved in other legal proceedings and claims which arise
in the ordinary course of its business. While any litigation contains an element
of uncertainty, management believes that the outcome of such litigation will not
have a material adverse effect on the Company's financial position or results of
operations.
 
STAND-BY LETTERS OF CREDIT
 
The Company maintains a letter of credit facility with a bank that provides for
the issuance of stand-by letters of credit and requires the payment of a fee of
1.0% per annum of the amounts outstanding under the facility. The facility
expires January 31, 2000. At August 2, 1998 stand-by letters of credit
aggregating $1,505,285 were outstanding under this facility.

The 1997 and 1996 tax provisions reflect the utilization of prior year net
operating loss carryforwards. In 1995 a valuation allowance had been provided to
reduce deferred tax assets to their net realizable value primarily based on
management's uncertainty that past performance would be indicative of future
earnings. In 1997 the valuation allowance was reversed through the deferred tax
provision. A determining factor in assessing the change was the cumulative
income in recent years.

NOTE M -- EMPLOYEE BENEFIT PLANS
 
In August 1985, the Board of Directors approved an Employee Savings Plan which
qualified as a thrift plan under Section 401(k) of the Internal Revenue Code.
This Plan, as amended and restated, allows employees to contribute between 2%
and 15% of their salaries to the Plan. The Company, at its discretion can
contribute 100% of the first 2% of the employees' contribution and 25% of the
next 4%. Additional Company contributions can be made depending on profits. The
aggregate benefit payable to an employee is dependent upon his rate of
contribution, the earnings of the fund, and the length of time such employee
continues as a participant.
 
The Company has accrued approximately $197,000 for the 52 weeks ended August 2,
1998, and contributed approximately $181,000, and $159,000 to this plan for the
53 weeks ended August 3, 1997 and the 52 weeks ended July 28, 1996,
respectively.

NOTE O -- SHAREHOLDERS' EQUITY
 
At the annual meeting of stockholders held on February 18, 1998, the
stockholders of the Company approved a proposal to amend the Certificate of
Incorporation to increase the authorized shares of Common Stock from 10,000,000
to 20,000,000 shares.
 
In December 1997, the Company completed the sale of 1,100,000 shares of common
stock to the public, of which 700,000 shares were sold by the Company and
400,000 shares were sold by certain selling stockholders. In addition, the
Company also sold 1,265,000 Common Stock Purchase Warrants. The Company received
net proceeds of $7,451,579 after underwriting discounts and commissions and
other expenses of the offering. Each Warrant entitles the holder to purchase one
share of common stock at $14.40 per share (subject to adjustment under certain
conditions) through January 1999 and thereafter at $15.60 per share until they
expire in January 2000. The Company has also issued to the underwriters, for
their own accounts, warrants to purchase 110,000 shares of common stock of the
Company (subject to adjustment under certain circumstances), exercisable for a
period of twenty-five months at a price of $14.40 per share through January
1999, and at a price of $15.60 per share through their expiration in January
2000.
 
On September 4, 1997 the Board of Directors declared a 4-for-3 stock split
effected as a stock dividend payable September 30, 1997 to holders of record on
September 15, 1997. The amount of $105,234 was transferred from additional
paid-in capital to the common stock account to record this distribution. All
share and per share data, including stock options and warrants, included in the
financial statements have been restated to reflect the stock split.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
The Company has two fixed option plans which reserve shares of common stock for
issuance to executives, key employees and directors. The Company applies APB
Opinion No.25 and related Interpretations in accounting for these plans.
Statement of Financial Accounting Standards No.123, "Accounting for Stock-Based
Compensation" ("SFAS 123") was issued by the FASB in 1995 and, if fully adopted,
changes the methods for recognition of cost on plans similar to those of the
Company. The Company has adopted the disclosure-only provisions of SFAS 123.
Accordingly, no compensation cost has been recognized for the stock option
plans. Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of that
Statement. The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions: risk-free interest rate of 4.9%; volatility factor of the expected
market price of the Company's common stock of .59; and a weighted-average
expected life of the option, after the vesting period, of .4 years.
 
The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
Had compensation cost for stock options granted in fiscal 1998 and 1997 been
determined based on the fair value at the grant date consistent with the
provisions of SFAS No. 123, the Company's net earnings and earnings per share
would have been reduced to the pro forma amounts indicated below using the
statutory income tax rate of 34%:

be representative of the effects on reported net earnings for future years due
to the various vesting schedules.

market value at the date of grant. Prices for incentive stock options granted to
employees who own 10% or more of the Company's stock are at least 110% of market
value at date of grant. The nature and terms of the options to be granted is
determined at the time of grant by the Board of Directors. The options expire
ten years from the date of grant, subject to certain restrictions. Options for
88,333 and 801,660 shares were granted during the fiscal years ended August 2,

determined at the time of grant by the Board of Directors. If not specified,
100% of the shares can be exercised one year after the date of grant. The
options expire ten years from the date of grant. Options for 663,989 shares were
granted during the fiscal year ended August 3, 1997. In December 1992, the Board
of Directors approved the 1992 Non-Qualified Stock Option Plan which covers
1,333,333 shares, as amended, of the Company's common stock. Under the terms of
the Plan, the purchase price of the shares, subject to each option granted, is
100% of the fair market value at the date of grant. The date of exercise is
determined at the time of grant by the Board of Directors; however, if not
specified, 50% of the shares can be exercised each year beginning one year after
the date of grant. The options expire ten years from the date of grant. Options
for 339,986 shares were granted during the fiscal year ended July 30, 1995.
These options may be exercised cumulatively at the rate of 25% per year
beginning one year after the date of grant. This plan was terminated in December
1995, except for outstanding options thereunder.
 
In October 1987, the Board of Directors approved the 1988 Non-Qualified Stock
Option Plan which covers 666,666 shares of the Company's common stock. Under the
terms of the Plan, the purchase price of the shares, subject to each option
granted, will not be less than 85% of the fair market value at the date of
grant. The date of exercise may be determined at the time of grant by the Board
of Directors; however, if not specified, 20% of the shares can be exercised each
year beginning one year after the date of grant and generally expire five years
from the date of grant. This plan was terminated in December 1995, except for
outstanding options thereunder.

In April 1993, common stock warrants were issued to certain officers and
directors for the right to acquire 573,333 shares of common stock of the Company
at the fair market value of $5.35 per share at date of issue. In December 1995
warrants for 533,333 shares were canceled, and the remaining 40,000 warrants
were exercised in fiscal 1998. In December 1995, common stock warrants were
issued to certain officers for the right to acquire 293,333 shares of common
stock of the Company at the fair market value of $4.64 per share at date of
issue. The warrants vest immediately and expire December 13, 2005. Warrants for
13,333 shares were exercised in fiscal 1997.
 
NOTE P -- MAJOR CUSTOMERS
 
Net sales to the U.S. Government in 1998, 1997, and 1996 accounted for
approximately 26%, 34%, and 33% of net sales, respectively. Foreign sales
amounted to approximately $11,943,000, $9,398,000, and $6,556,000 in fiscal
1998, 1997, and 1996, respectively.
 
Included in accounts receivable as of August 2, 1998 and August 3, 1997 are
amounts due from the U.S. Government of approximately $933,000 and $1,454,000,
respectively.
 
NOTE Q -- FAIR VALUES OF FINANCIAL INSTRUMENTS
 
The following methods and assumptions were used by the Company in estimating its
fair value disclosures for financial instruments:
 
Cash and cash equivalents: The carrying amount reported in the balance sheet for
cash and cash equivalents approximated its fair value.
 
Notes receivable-officers: The carrying amount reported in the balance sheet for
notes receivable from officers approximated its fair value.
 
Available-for-sale securities: The fair value of available-for-sale securities
was based on quoted market prices.
 
Long-term debt: The fair value of the mortgage note was estimated using
discounted cash flow analysis, based on the Company's current incremental
borrowing rate for similar types of borrowing arrangements.
 
Off balance sheet financial instruments:
 
Stand-by letters of credit: These letters of credit primarily collateralize the
Company's obligations to customers for advanced payments received under
contracts. The contract amounts of the letters of credit approximate their fair
value.
 
The carrying amounts and fair values of the Company's financial instruments are
presented below:

                          INDEPENDENT AUDITORS' REPORT
 
To the Stockholders and Board of Directors
General Microwave Corporation:
 
We have audited the consolidated financial statements of General Microwave
Corporation and subsidiaries as listed in the accompanying index. In connection
with our audits of the consolidated financial statements, we have also audited
the financial statement schedule as listed in the accompanying index. These
consolidated financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedule based on our audits. We did not audit the consolidated financial
statements of General Microwave Israel Corporation, an indirect wholly-owned
subsidiary, as of and for the years ended February 28, 1998 and 1997 and
February 29, 1996, which statements reflect total assets constituting 19%, 26%
and 17% and total revenues constituting 18%, 15% and 11%, respectively, after
elimination of intercompany balances and sales, of the related consolidated
totals. Those statements were audited by other auditors whose reports have been
furnished to us, and our opinion, insofar as it relates to the amounts included
for General Microwave Israel Corporation, is based solely on the reports of the
other auditors.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, based on our audits and the reports of the other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of General Microwave Corporation and
subsidiaries as of February 28, 1998 and 1997 and the results of their
operations and their cash flows for each of the years in the three-year period
ended February 28, 1998, in conformity with generally accepted accounting
principles. Also in our opinion, based on our audits and the reports of the
other auditors, the related financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

                    AUDITORS' REPORT TO THE SHAREHOLDERS OF
             GENERAL MICROWAVE (ISRAEL) CORPORATION AND SUBSIDIARY
 
We have audited the accompanying consolidated balance sheets of General
Microwave (Israel) Corporation ("the Company") and subsidiary as of February 28,
1998 and February 28, 1997, and the related consolidated statements of
operations, changes in shareholders' deficiency and cash flows for the years
then ended. These financial statements are the responsibility of the Company's
Board of Directors and management. Our responsibility is to express an opinion
on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards, including those prescribed under the Israeli Auditors' Regulations
(Auditor's Mode of Performance) -- 1973, which auditing standards are
substantially identical to generally accepted auditing standards in the United
States. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Board of Directors and management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
The aforementioned financial statements have been prepared in U.S. dollars as
described in Note 2A.
 
As stated in Note 1B, the consolidated financial statements were prepared at the
request of the parent company and for its use only. The financial statements do
not include activities of the Company, if any, that are not directly reflected
in its books and records maintained in Israel.
 
In our opinion, except for the matter discussed in the preceding paragraph, the
financial statements present fairly, in all material respects, the consolidated
financial position of the Company and subsidiary as of February 28, 1998 and
February 28, 1997, and the consolidated results of operations, changes in
shareholders' deficiency and cash flows for the years then ended in accordance
with generally accepted accounting principles in Israel. As applicable to these
financial statements, such accounting principles are substantially identical in
all material respects to generally accepted accounting principles in the United
States, except as otherwise described in Note 22 to the consolidated financial
statements.
 
Pursuant to Section 211 of the Companies Ordinance (New Version) -- 1983, we
hereby state that we received all the information and explanations which we
requested and that our opinion on the consolidated financial statements is given
based on the best of the information and explanations which we received and as
reflected in the books of the Company.

(a) DESCRIPTION OF BUSINESS
 
General Microwave Corporation and its subsidiaries (the Company) are engaged
primarily in the design, development, manufacture and marketing of microwave
equipment and components. The Company is organized into three operating
divisions in separate locations. A majority of the Company's microwave products
are sold to manufacturers and users of microwave systems and equipment for
applications in the defense electronics industry. The Company also sells these
components and equipment for use in the industrial sector, as well as in
commercial telecommunications industries. Typical applications for the Company's
microwave products include electronic warfare and countermeasures; airborne and
shipboard navigation and communications; radar systems; missile guidance
systems; automatic test equipment; and satellite communications. On February 25,
1997, the Board of Directors of the Company adopted a plan to discontinue its
fiber optics business operated by its wholly-owned subsidiary, Math Associates,
Inc. On September 24, 1997, a sale of certain assets of Math Associates, Inc.
was completed (note 2).
 
A substantial portion of the Company's revenues is derived from military
sources. The Company manufactures components and instruments for a number of
ongoing military programs and is currently engaged in the design and manufacture
of prototypes in connection with various electronic countermeasures, electronic
warfare, radar, navigation and communications programs of the United States
Government and foreign governments and agencies thereof.
 
(b) PRINCIPLES OF CONSOLIDATION
 
The consolidated financial statements include the accounts of General Microwave
Corporation (GMC), its wholly-owned subsidiaries, General Microwave Foreign
Sales Corporation (FSC), Micro-El Patent Corporation and GMC Associates, Inc.
(formerly known as Math Associates, Inc. (Math)); its indirect wholly-owned
subsidiaries, General Microwave Israel Corporation (GMIC) and General Microwave
Israel (1987) Ltd. (GMIL); and its majority-owned subsidiary, General
Microcircuits Corporation (GMCC). All inter-company accounts and transactions
have been eliminated in consolidation.
 
(c) REVENUE RECOGNITION
 
Sales are recorded as units are delivered with the cost of sales recognized on
each shipment based upon an average estimated final contract unit cost,
including overhead costs. Losses on contracts are recorded when known.
 
(d) CASH EQUIVALENTS
 
For purposes of the consolidated statements of cash flows, the Company considers
all highly liquid investments with original maturities of three months or less
to be cash equivalents. There were no cash equivalents at February 28, 1998 and
1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
(e) INVENTORIES
 
Work-in-process inventory reflects all accumulated production costs, which are
comprised of direct production costs and overhead, reduced by amounts
attributable to units delivered. Work-in-process inventory is reduced to its
estimated net realizable value by a charge to cost of sales in the period excess
costs are identified. Raw materials and finished goods inventories are reflected
at the lower of cost or market, computed on the first-in, first-out (FIFO)
method.
 
(f) PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment are recorded at cost. Depreciation is charged to
operations over the estimated service lives of the related assets (ranging from
three to twenty-five years) using the straight-line method. Assets acquired
under capital lease and leasehold improvements are amortized over the life of
the lease or the estimated life of the asset, whichever is less.
 
(g) DEBT ISSUANCE COSTS
 
Costs incurred in connection with the issuance of Industrial Development Revenue
Bonds, amounting to $313,000, are being amortized over the life of the bonds
(fifteen years) on a straight-line basis.
 
(h) INTANGIBLE ASSETS
 
Intangible assets include patents recorded at cost which are amortized on a
straight-line basis over a period not to exceed seventeen years. Accumulated
amortization aggregated $92,629 and $78,311 at February 28, 1998 and 1997,
respectively.
 
The costs in excess of fair value of net assets acquired relate to the
acquisition of GMCC and are amortized on a straight-line basis over fifteen
years. Additionally, these costs include the cost of additional ownership of
GMCC increasing from 80% to 97% (note 6), which are amortized on a straight-line
basis over the remaining life of the original asset. Accumulated amortization
aggregated $387,109 and $311,578 at February 28, 1998 and 1997, respectively.
 
(i) PENSION EXPENSE
 
Pension expense for eligible employees is provided under an actuarial cost
method. The Company's policy is to make annual contributions to the plan in
accordance with actuarially determined funding requirements.
 
(j) RESEARCH AND DEVELOPMENT
 
Company funded research and development, net of research and development grants,
is charged directly to expense as incurred. Customer funded research and
development is recognized in net sales while the applicable costs are charged to
cost of sales.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
(k) INCOME TAXES
 
Income taxes are accounted for under the asset and liability method. Deferred
tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized.
 
(l) EARNINGS PER SHARE
 
Earnings per share is computed in accordance with the provisions of Statement of
Financial Accounting Standards No. 128 (SFAS 128), "Earnings per Share", which
became effective for the Company as of February 28, 1998. SFAS 128 requires the
presentation of basic and diluted earnings per share. As required by SFAS 128,
earnings per share for all prior periods presented have been restated. Basic
earnings per share is computed by dividing income available to common
shareholders (which for the Company equals its recorded net income) by the
weighted average number of common shares outstanding during the period. Diluted
earnings per share reflects the potential dilution that could occur if
securities or other contracts to issue common stock, such as stock options, were
exercised, converted into common stock or otherwise resulted in the issuance of
common stock.
 
(m) RECONCILIATION TO UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
 
The financial statements of the Company's Israeli operations, GMIC and GMIL,
were prepared in accordance with generally accepted accounting principles in
Israel. The differences between generally accepted accounting principles in
Israel and generally accepted accounting principles in the United States as they
pertain to GMIC and GMIL are not considered material to the consolidated
financial statements of the Company.
 
(n) FOREIGN CURRENCY TRANSLATION
 
The financial position and the results of operations of the Company's Israeli
operations are measured using the dollar as the functional currency. Gains or
losses resulting from translating transactions denominated in a foreign currency
were immaterial in fiscal 1998, 1997, and 1996.
 
(o) IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF
 
The Company adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," on
March 1, 1996. SFAS No. 121 requires that long-lived assets and certain
identifiable intangibles be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net
 
                                      F-38
<PAGE>   140
                 GENERAL MICROWAVE CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by
which the carrying amount of the assets exceed the fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying amount or
fair value less costs to sell. SFAS No. 121 did not have a material impact on
the Company's financial position or results of operations in fiscal 1998 or
1997.
 
(p) STOCK OPTION PLAN
 
Prior to March 1, 1996, the Company accounted for its stock option plan in
accordance with the provisions of Accounting Principles Board (APB) Opinion No.
25, "Accounting for Stock Issued to Employees", and related interpretations. As
such, compensation expense would be recorded on the date of grant only if and to
the extent that the current market price of the underlying stock exceeded the
exercise price. On March 1, 1996, the Company adopted SFAS No. 123, "Accounting
for Stock-Based Compensation," which permits entities to recognize as expense
over the vesting period the fair value of all stock-based awards on the date of
grant.
 
Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB Opinion No. 25 and provide pro forma net income and pro forma
earnings per share disclosures for employee stock option grants as if the
fair-value-based method defined in SFAS No. 123 had been applied. The Company
has elected to continue to apply the provisions of APB Opinion No. 25 and
provide the pro forma disclosure provisions of SFAS No. 123.
 
(q) USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company's management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
(r) RECLASSIFICATIONS
 
Reclassifications are made whenever necessary to conform with the current year's
presentation.
 
(2) DISCONTINUED OPERATIONS
 
Pursuant to a Board of Directors resolution on February 25, 1997, the Company
adopted a plan to discontinue its electronic fiber optic systems and components
business. At February 28, 1997, a provision for loss on disposal of $2,660,455
was recorded in the accompanying consolidated financial statements principally
relating to the anticipated disposal of inventory and other assets, estimated
losses during the phase-out period and estimated costs of liquidation. This
business was operated by Math.
 
On September 24, 1997, a sale of certain of the assets of Math was completed,
which resulted in a gain from discontinued operations as recorded in the
consolidated financial statements as of February 28, 1998. This gain relates
principally to the proceeds of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
$353,855 from the sale of assets and $598,956 from the reversal of estimated
costs of liquidation which will no longer be incurred as a result of the sale
and provision for operating losses during the phase out period that did not
materialize.
 
The consolidated financial statements of the Company have been reclassified to
reflect the effects of the Company's decision to account for the disposal of its
Math operations as discontinued operations. Accordingly, the net sales, costs
and expenses, assets and liabilities, and cash flows associated with Math have
been excluded from the respective captions in the accompanying consolidated
balance sheets, statements of operations and statements of cash flows.
 
Net sales of the discontinued operations were $1,917,298, $4,735,586 and
$4,908,579 for fiscal 1998, 1997 and 1996, respectively.
 
The following summarizes assets and liabilities of the discontinued operations
which have been segregated in the accompanying consolidated balance sheets:

Discontinued operations include management's best estimates of amounts expected
to be realized on the remaining liquidation of the Math business. While these
estimates are based on an analysis of the recoverability of assets and estimated
expenses, actual results may differ.

Depreciation expense aggregated $645,255, $698,609 and $774,006 in fiscal 1998,
1997 and 1996, respectively. Repairs and maintenance costs are expensed as
incurred and amounted to approximately $454,000, $410,000 and $362,000 in fiscal
1998, 1997, and 1996, respectively.
 
The Company's Israeli operations were granted "approved enterprise status" and
are therefore entitled to investment grants from the Israeli government for
investments in production facilities. Such approval is conditional upon meeting
certain export requirements, once implementation of the investment program has
been completed. Investment grants reflected as an offset against the cost of
property and equipment amounted to $1,120,666 and $1,063,523 at February 28,
1998 and 1997, respectively. The conditions for receipt of grants in the amount
of $713,097 were fulfilled as of February 28, 1997. Should the Company not
fulfill the conditions applicable to receipt of the remaining grants, the

Israeli government is permitted to demand refund of the balance of $407,569,
plus interest. The Company is required to invest an additional $210,000 to
comply with the existing investment program. In management's opinion, the
Company will fulfill the relevant conditions relating to investment grants
received.
 
(6)  MAJORITY-OWNED SUBSIDIARY
 
At February 28, 1998, the Company owns 97% of GMCC's outstanding common stock
(291,000 shares). Additionally, the Company owns all of the outstanding
preferred stock of GMCC. The interest in the investment in GMCC outstanding
common stock not owned by the Company is recorded as minority interest on the
accompanying consolidated balance sheets.

In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Management considered the
scheduled reversal of deferred tax assets and liabilities, projected future
taxable income, and tax planning strategies in making this assessment. Based
upon projections of future taxable income over the periods which the deferred
tax assets are deductible, management believes it is more likely than not that
the Company will realize the benefits of the net deferred tax assets. The amount
of the deferred tax assets considered realizable, however, could be reduced in
the near term if estimates of future taxable income are reduced.
 
At February 28, 1998, the Company has Federal net operating loss carryforwards
of approximately $990,000, New York State net operating loss carryforwards of
approximately
 
$578,000 and New York State tax credits of $243,000 which are available to
offset future taxable income, if any. These Federal and state net operating loss
carryforwards and state tax credits, which arose from both continuing and
discontinued operations, are available to offset future taxable income of
continuing operations. The Federal and New York State net operating loss
carryforwards expire starting in fiscal 2010.

Under the terms of an agreement with the Town of Babylon Industrial Development
Agency and a bank, the Agency issued 1984 Variable Rate 7-Day Demand Industrial
Development Revenue Bonds in the amount of $6,000,000 to provide a substantial
portion of the funds for the construction and equipping of the Company's
manufacturing facility in Amityville, New York. Interest is payable
semi-annually at a variable rate which approximates 65% of the yield on 13-week
U.S. Treasury bills. Such rate was 3.40% and 3.25% at February 28, 1998 and
1997, respectively. Under the terms of the agreement, the Company obtained an
irrevocable bank letter of credit for the amount of the bonds plus certain
interest. The letter of credit, which amounted to approximately $1,373,000 and
$1,877,000 at February 28, 1998 and 1997, respectively, will be drawn on in the
event the Town of Babylon defaults on its obligations to the bondholders. This
letter of credit expires on September 15, 1998 and management is presently
negotiating the letter of credit with the bank. At any time prior to maturity,
the bonds are redeemable at the option of the Company at a redemption price of
100%. The bonds are due on October 1, 1999 with annual payment requirements of
$600,000 in fiscal 1999 and 2000. All property, plant and equipment acquired or
constructed by the Company with the proceeds of the bonds collateralize the
obligation.
 
The aforementioned bond agreement includes certain restrictive covenants, as
amended. The Company must, among other things, maintain profitable operations, a
minimum ratio of current assets to current liabilities, a minimum level of
tangible net worth, as defined and amended, and must not exceed a specified debt
to equity ratio. The tangible net worth covenant limits the ability of the
Company to pay cash dividends. As a result of such covenant there is
approximately $1,652,623 of unrestricted funds available for the payment of cash
dividends as of February 28, 1998. In addition, commencing April 1, 1996, the
Company is required to make monthly sinking fund payments of $40,000 towards its
annual bond payment. Such amount is reflected as restricted cash on the
accompanying consolidated balance sheet as of February 28, 1998.
 
During fiscal 1992 the Company's subsidiary, GMIL, entered into a capital lease
on its operating facility in the Talpiot Industrial Zone of Jerusalem, Israel at
a cost of $841,875. This transaction was primarily financed with a $750,000
long-term bank loan at an interest

rate of LIBOR plus 1.5% (7.20% at February 28, 1997), of which $281,250 and
$356,250 was outstanding at February 28, 1998 and 1997, respectively. The loan
is secured by the premises, all of GMIL's assets and a guarantee by the Company
of $300,000.
 
Required principal payments on long-term debt are summarized as follows:

(9) SHORT-TERM BORROWING
 
The Company's Israeli subsidiary has outstanding short-term borrowings with a
bank aggregating $230,319 and $591,739 at interest rates of 6.05% and ranging
from 6.95% to 8.40% at February 28, 1998 and 1997, respectively. The short-term
borrowings were repaid in full in March 1998.
 
(10) EARNINGS PER SHARE
 
As discussed in note 1(l), the Company adopted SFAS No.128, which replaces the
calculation of primary and fully diluted earnings (loss) per share with basic
and diluted earnings (loss) per share. Prior periods have been restated to
conform to SFAS No.128 requirements. A reconciliation between numerators and
denominators of the basic and diluted earnings (loss) per share is as follows:

(12) STOCKHOLDERS' EQUITY
 
The 1990 Stock Option Plan (1990 Plan) provides for the issuance of up to
125,000 shares of common stock to key employees including officers and directors
who are employees. Options under the 1990 Plan, which expires on June 26, 2000,
may be either incentive stock options (ISO) or options not qualified under the
Internal Revenue Code. The purchase price of common stock under each option
shall be determined by the Stock Option Committee of the Board of Directors;
provided, however, that the stock purchase price pursuant to an ISO may not be
less than the fair market value of the common stock subject to the option on the
date that the option was granted, and may in no event be less than the par value
of the stock. Options granted to date under the 1990 Plan were at the fair
market value at the date of grant. Options vest 25% after nine months from the
date of grant and every nine months, thereafter. The 1990 Plan permits option
holders to pay the option exercise price with previously owned common stock of
the Company or a combination of cash and common stock. If any employee to whom
an ISO is granted owns common stock amounting to more than 10% of the total
voting power of all classes of stock of the Company, the option exercise price
must be at least 110% of the fair market value of common stock at the time the
option is granted and the option must terminate no later than five years from
the date the option is granted. At February 28, 1998, 39,250 options outstanding
are exercisable under the 1990 Plan.
 
In January 1997, the Company adjusted the exercise price of all outstanding
options to $5.00 per share, the then fair market value of the stock.

The 1997 Non-Employee Director Stock Option Plan (1997 Plan) provides for the
issuance of options to purchase 2,500 shares of common stock to each
non-employee director of the Company on the date of each annual meeting of
shareholders, up to an aggregate of 60,000 shares, at the fair market value of
the common stock on the date of grant. 33% of the options are exercisable on the
first day of the calendar year following the annual meeting of shareholders, 33%
on the first day of the second year; and 34% on the first day of the third year.
Generally options expire ten years after the option grant date or three months
after termination of service as a director, which ever is earlier.

The Company has an Employee Stock Purchase Plan which offers eligible employees
options to purchase common stock of the Company at a purchase price of 85% of
the lesser of the average market value of the common stock on the date of grant
or on the exercise date. The exercise date is the last business day of the
twenty-fifth month following the date of grant. Payment for the shares is made
through payroll deductions over a two-year period. The maximum number of shares
that may be issued under this Plan, as amended, is 140,000.

</TABLE>
 
The per share weighted average fair value of stock options granted during fiscal
1998, 1997 and 1996 was $3.37, $3.36 and $3.43 respectively. The fair value of
each option grant is estimated on the date of grant using the Black-Scholes
option pricing model with the following weighted-average assumptions used for
grants in fiscal 1998, 1997 and 1996, respectively: expected volatility of 27%,
15% and 20%; risk-free interest rates of 6.66%, 6.41% and 6.33%; expected lives
of 10.0, 7.1 and 10.0 years; and no dividend yields.
 
Pro forma net income reflects only options granted in fiscal 1998, 1997 and
1996. Therefore, the full impact of calculating compensation cost for stock
options under SFAS No. 123 is not reflected in the pro forma net earnings (loss)
amounts presented above because compensation cost is reflected over the options'
vesting period and compensation cost for options granted prior to March 1, 1995
is not considered.
 
(13) FINANCIAL INSTRUMENTS
 
SFAS Statement No. 107, Disclosures about Fair Value of Financial Instruments,
defines the fair value of a financial instrument as the amounts at which the
instrument could be exchanged in a current transaction between willing parties.
The carrying value of all financial instruments classified as a current asset or
current liability are deemed to approximate fair value because of the short
maturity of these instruments. In the opinion of management, the carrying value
of the Company's bank loan payable (note 8) approximates fair value as the
interest rate is based on the current LIBOR rate and such rate is believed to
approximate the rates that would be offered to GMIL for debt of the same
remaining maturities.
 
It is not practicable to estimate the fair value of the Company's Industrial
Development Revenue Bonds of $1,200,000 and $1,700,000 as of February 28, 1998
and 1997, respectively. The fair value of such bonds would be based upon the
rates an Industrial Development Agency would charge the Company to finance the
construction and/or equipping of a new manufacturing facility. Such rates are
not readily determinable, without incurring excessive cost. However, because the
carrying value of the bonds are based upon

a rate that fluctuates with a U.S. Treasury rate, management is of the opinion
that the difference between the carrying value and fair value would not be
material.
 
(14) ROYALTIES
 
The Office of the Chief Scientist (OCS) of the Ministry of Commerce and Industry
in Israel has approved grants to GMIC and GMIL for research and development
projects, which resulted in the manufacturing of products for sale.
 
For such projects which are commercially successful, the OCS is to be paid
royalties of 2% of gross annual sales, up to the amount of the grant received.
In fiscal 1998, GMIC and GMIL paid royalties of $117,739 to the OCS.
 
The Israel -- United Bi-national Industrial Research & Development Foundation
(BIRD) approved grants for research and development projects, which resulted in
the manufacturing of products for sale. The Company is required to pay royalties
to BIRD up to a maximum of 150% of the grant received, from the sale of such
products. In fiscal 1998, the Company paid royalties of approximately $99,000 to
BIRD.
 
(15) BUSINESS AND CREDIT CONCENTRATIONS
 
The Company's operations are in a single industry segment and involve the
manufacture of various types of microwave, electronic equipment and components.
The majority of the Company's business is defense related and consists of direct
and indirect sales to the United States Government and foreign governments or to
other companies that are manufacturing products for the defense industry.

In determining operating earnings (loss) for each geographic area, sales and
purchases between areas have been accounted for on the basis of internal prices
set by the Company. Identifiable assets are those tangible and intangible assets
used in operations in each geographic area. Identifiable assets of the Israeli
operations include trade accounts receivable from GMC of $201,476, $603,125 and
$116,464 as of February 28, 1998 and 1997 and February 29, 1996, respectively.
 
(b) CREDIT CONCENTRATIONS
 
During fiscal 1998, 1997 and 1996, after giving effect to discontinued
operations, one customer represented 16%, 26% and 10% of net sales,
respectively, of the Company. In addition, the Company had six and five
customers with individual balances in excess of 5% of accounts receivable, which
aggregated approximately $2,758,000 and $2,200,000, at February 28, 1998 and
1997, respectively.
 
The Company grants credit to customers based upon analysis of their financial
position and other factors. Consequently, an adverse change in those factors
could affect the Company's estimate of its bad debts. The Company estimates an
allowance for doubtful accounts based upon the creditworthiness of its customers
as well as general economic conditions. As the majority of the Company's sales
are made and credit is granted to the United States Government and customers in
the defense industry, the Company considers the credit risks associated with its
customers to be minimal.

                          AGREEMENT AND PLAN OF MERGER
 
AGREEMENT AND PLAN OF MERGER (herein "this Agreement") dated as of August 21,
1998 by and among General Microwave Corp., a New York corporation ("GMC"),
eleven GMC shareholders identified on Exhibit "A" hereto (the "Participating
Shareholders"), GMC Acquisition Corporation, a New York corporation
("Acquisition") and Herley Industries, Inc. ("Herley"), a Delaware Corporation.
 
                              W I T N E S S E T H:
 
WHEREAS, Acquisition (which is a wholly-owned subsidiary of Herley) desires to
merge with GMC and be the surviving corporation after such merger and GMC and
the Participating Shareholders (being among the principal shareholders of GMC)
also desire that Acquisition merge with GMC upon the terms and conditions set
forth herein and in accordance with the Business Corporation Law of the State of
New York (the "BCL"), and that the outstanding shares of Common Stock, par value
$.01 per share, of GMC (referred to collectively as the "GMC Shares" and
individually as a "GMC Share") be converted upon such merger (the "Merger") into
the right to receive a warrant to purchase Herley Common Stock and cash in the
amount set forth in Section 2.1 hereof (Acquisition and GMC sometimes being
hereinafter referred to as the "Constituent Corporations" and Acquisition,
following the effectiveness of the Merger, as the "Surviving Corporation"); and
 
WHEREAS, the respective Boards of Directors of Acquisition and GMC have approved
this Agreement and the Merger;
 
NOW, THEREFORE, in consideration of the mutual representations, warranties,
covenants, agreements and conditions contained herein, and in order to set forth
the terms and conditions of the Merger and the mode of carrying the same into
effect, the parties hereto agree as follows:
 
                                   ARTICLE I
 
                           PRINCIPAL TERMS OF MERGER
 
1.1  Surviving Corporation.  At the Effective Time (as defined in Section 1.3
hereof), GMC shall be merged with and into Acquisition upon the terms and
conditions hereinafter set forth as permitted by and in accordance with the BCL.
At the Effective Time, the identity and separate existence of GMC shall cease,

place as the parties may agree, as soon as practicable (and in any event not
later than three business days) following the meeting of the shareholders of GMC
referred to in Section 1.5 hereof, subject to adjournment in the event a
condition set forth in Article VI hereof shall not have been fulfilled at such
time notwithstanding the best efforts of the parties hereto, and shall not have
been waived, in which event the Closing shall take place as soon as practicable
(and in any event not later than three business days) following the satisfaction
or waiver of all of such conditions, or at such other time and place or on such
other date
 
                                       A-1
<PAGE>   169
 
as GMC and Acquisition may mutually agree upon (the date and time of such
Closing being herein referred to as the "Closing Date").
 
(b) Subject to the provisions of Article VI hereof, the Surviving Corporation

such Certificate to be filed with the New York Secretary of State (the
"Secretary") and recorded in accordance with the applicable provisions of
Section 904 of the BCL.
 
1.3  Effective Time.  The Merger shall become effective when the Certificate of
Merger is filed by the Secretary in accordance with the applicable provisions of
the BCL (or at such later time specified as the effective time in the
Certificate of Merger), which Certificate shall be submitted for filing as soon
as practicable after all of the conditions set forth in Article VI are fulfilled
or waived, provided that this Agreement has not been previously terminated
pursuant to Section 7.1 hereof. The date and time when the Merger shall become
effective are herein referred to as the "Effective Time."
 
1.4  Certificate of Incorporation.  The Certificate of Incorporation of the
Surviving Corporation from and after the Effective Time shall be as set forth in
Exhibit B to this Agreement, until thereafter further amended as provided by
law.
 
1.5  Meetings of Herley and GMC Shareholders.  Herley and GMC shall take all
action necessary in accordance with their appropriate state law and their
respective Certificates of Incorporation and By-laws and the Securities Exchange
Act of 1934 and the rules and regulations of the applicable exchange to each
hold a meeting of its shareholders as soon as reasonably possible to consider
and vote upon the adoption of this Agreement and the authorization of the
Merger. In no event shall such meeting be held earlier than 20 business days
following the date on which proxy or information statements (the "Proxy
Statements") are sent to the stockholders of Herley and GMC.
 
                                   ARTICLE II
 
                      STATUS AND CONVERSION OF SECURITIES
 
2.1  Status and Conversion of GMC shares.  At the Effective Time, by virtue of
the Merger and without any action on the part of the holders thereof:
 
(a)   Any GMC Shares held by GMC as treasury shares shall be cancelled and
      retired.
 
(b)   Each then outstanding GMC Share remaining (other than GMC Shares to be
      cancelled in accordance with Section 2.1(a) hereof and other than GMC
      Shares held by shareholders of GMC who properly exercise dissenters'
      rights available under the BCL ("Dissenting Shares")) shall be converted
      into the right to receive $18.00 in cash, without interest and a warrant
      to receive one share of Herley's Common Stock, $.10 par value, in
      accordance with the terms and conditions contained in the form of warrant
      attached hereto as Exhibit C, which warrant shall lapse, if not earlier
      exercised, three (3) years from the date of issuance.
 
(c)   If, between the date of this Agreement and the Effective Time, the
      outstanding GMC Shares shall have been changed into a different number of
      shares or a different class by reason of any reclassification,
      recapitalization, split-up, combination, exchange of shares or
      readjustment, or a stock dividend thereon shall be declared with a record
      date within said period, the merger price per share set forth in Section
      2.1(b) hereof shall be correspondingly adjusted. GMC covenants and agrees
      not to take any action referred to in the preceding sentence.
 
                                       A-2
<PAGE>   170
 
(d)   Each Dissenting Share as to which a written objection to the Merger is
      filed in accordance with Section 623 of the BCL at or prior to the vote of
      GMC shareholders on the Merger taken at the meeting of such shareholders
      referred to in Section 1.7 hereof and not withdrawn at or prior to the
      time of such vote and which is not voted in favor of the Merger shall not
      be converted into a right to receive cash and warrants hereunder unless
      and until the holder shall have effectively withdrawn or lost his right to
      payment for his GMC Shares under such Section 623, at which time his GMC
      Shares shall be converted into a right to receive cash and warrants in
      accordance with Section 2.1(b).
 
2.2  GMC Stock Options and Warrants.  All outstanding options or warrants or
other rights (referred to collectively as the "Options" and individually as an
"Option") to purchase GMC Shares shall, whether or not exercisable or vested,
become fully exercisable and vested, and each holder of an Option shall be
entitled to receive from Acquisition, at the Effective Time, for each Share of
GMC subject to an Option, an amount in cash in cancellation of such Option equal
to $18.00 less the per share exercise price of such Option, as such amount shall
be reduced by any amount required for withholding in accordance with applicable
federal and state tax laws and a warrant to receive one share of Herley's Common
Stock in the form of Exhibit D hereto. GMC's Board of Directors will adopt
resolutions terminating GMC's 1990 Stock Option Plan, 1997 Non-Employee
Directors Stock Option Plan and Employee Stock Purchase Plan (the "Option
Plans") effective as of the Effective Date.
 
2.3  Acquisition to Make Cash and Warrants Available.  At or before the
Effective Time, Acquisition shall make available to American Stock Transfer &
Trust Company, or such other entity as Acquisition shall designate to act as
paying agent (the "Paying Agent"), such funds (the "Payment Fund") as are
required for the conversion of GMC Shares and Options into the right to receive
cash pursuant to Section 2.1 hereof and Herley shall deliver to the Paying Agent
a global warrant with respect to such number of shares of its Common Stock as
would be delivered if all of GMC's Shares and Options were converted pursuant
thereto. The Payment Fund may be invested from time to time by the Paying Agent,
as directed by the Surviving Corporation, in (i) obligations of or guaranteed by
the United States of America or any State, (ii) commercial paper rated A-1 or
A-2, and/or (iii) time deposits with, including certificates of deposit issued
by, any office located in the United States of any bank or trust company that
has capital, surplus and undivided profits of at least $50,000,000, and any net
earnings with respect thereto shall be paid to the Surviving Corporation as and
when requested by the Surviving Corporation.
 
Prior to the Effective Time, GMC shall furnish to the Paying Agent a list
certified by an officer of GMC setting forth the names and addresses of all
persons entitled to receive funds and warrants with respect to Options under
Section 2.2 hereof, the number of Options held by each person and the exercise
prices thereof.
 
Promptly after the Effective Time, the Paying Agent shall mail to each record
holder of GMC Shares a form of letter of transmittal and instructions for use in
surrendering certificates representing such shares and receiving payment
therefor.
 
Each holder of GMC Shares or Options to be converted into the right to receive
consideration pursuant to this Article II shall be entitled to receive, upon
surrender to the Paying Agent of one or more certificates for such GMC Shares
for cancellation or the delivery of such documents of cancellation as may be
prescribed with respect to Options, a bank check made payable to such holder for
the amount of cash, without interest, into which the GMC Shares previously
represented by such certificates or Options are
 
                                       A-3
<PAGE>   171
 
convertible (under Sections 2.1 or 2.2, as the case may be) in the Merger and
shall deliver to the transfer agent for Herley's Common Stock such documentation
as shall be required to cause such transfer agent to deliver to such holder the
warrants with respect to the GMC Shares or Options. If a check and/or warrant is
to be sent to a person other than the person in whose name the certificates for
the GMC Shares surrendered for conversion are registered, it shall be a
condition of payment that the certificates so surrendered shall be properly
endorsed and the signatures thereon properly guaranteed and otherwise in proper
form for transfer and that the person requesting such payment shall pay to the
Surviving Corporation any transfer or other taxes required by reason of the
delivery of such check and related warrant to a person other than the registered
holder of the certificates surrendered, or shall establish to the satisfaction
of the Surviving Corporation that such taxes have been paid or are not
applicable. Until so presented and surrendered in exchange, each certificate
representing GMC Shares held by GMC shareholders (other than Dissenting Shares)
shall be deemed for all purposes to evidence only the right to receive the cash
and warrants to which such GMC Shares are entitled in accordance with Section
2.1 hereof.
 
Any portion of the Payment Fund not paid to holders of GMC Shares or Option
holders pursuant to this Agreement within twelve months after the Effective Time
shall be paid over by the Paying Agent to the Surviving Corporation together
with a list of holders of GMC Shares who have not yet surrendered certificates
for GMC Shares to the Paying Agent and such holders of GMC Shares shall
thereafter look only to the Surviving Corporation for payment, but shall have no
greater rights against the Surviving Corporation than may be accorded to general
creditors under applicable law. Notwithstanding the foregoing, neither the
Paying Agent, the Surviving Corporation nor any party hereto shall be liable to
a holder of GMC Shares for any cash delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.
 
                                  ARTICLE III
 
                           CERTAIN EFFECTS OF MERGER
 
3.1  Effect of Merger.  At and after the Effective Time, the separate existence
of GMC shall cease, the GMC Shares shall cease to exist (except as evidence of
the right of the holder thereof to receive cash and warrants therefor in
accordance with the terms hereof), subject to the rights of holders of
Dissenting Shares referred to in Section 2.1(b) hereof, and all rights,
privileges, powers and franchises, and all property, tangible and intangible, of
Acquisition and of GMC shall transfer to, vest in and devolve on the Surviving
Corporation without further act or deed. Confirmatory deeds, assignments, or
similar instruments to evidence such transfer may be executed and delivered at
any time in the name of GMC or Acquisition by GMC's last acting officers or by
the appropriate officers of the Surviving Corporation. The Surviving Corporation
shall be liable for all of the debts and obligations of Acquisition and GMC. Any
existing claim, action or proceeding pending by or against Acquisition or GMC
may be prosecuted to judgment as if the Merger had not taken place or, on motion
of the Surviving Corporation, the Surviving Corporation may be substituted as a
party, and any judgment against Acquisition or GMC shall constitute a lien on
the property of the Surviving Corporation. The Merger shall not impair the
rights of creditors or any liens on the property of either of the Constituent
Corporations.
 
3.2  Further Assurances.  If at any time after the Effective Time the Surviving
Corporation shall consider or be advised that any further deeds, assignments or
assurances in law or any other acts are necessary, desirable or proper (a) to
vest, perfect or confirm,
 
                                       A-4
<PAGE>   172
 
of record or otherwise, in the Surviving Corporation, the title to any property
or right of the Constituent Corporations acquired or to be acquired by reason
of, or as a result of, the Merger, or (b) otherwise to carry out the purposes of
this Agreement, the Constituent Corporations agree that the Surviving
Corporation and its proper officers and directors shall and will execute and
deliver all such property, deeds, assignments and assurances in law and do all
acts necessary, desirable or proper to vest, perfect or confirm title to such
property or right in the Surviving Corporation and otherwise to carry out the
purposes of this Agreement, and that the proper officers and directors of the
Constituent Corporations and the proper officers and directors of the Surviving
Corporation are fully authorized in the name of the Constituent Corporations or
otherwise to take any and all such action.
 
                                   ARTICLE IV
 
                         REPRESENTATIONS AND WARRANTIES
 
4.1  Representations and Warranties by GMC.  GMC represents and warrants to, and
agrees with, Acquisition and Herley, subject to the exceptions set forth in the
disclosure schedule (the "Schedule") attached hereto, as follows:
 
(a)   Organization of GMC.  GMC is duly incorporated and is validly existing as
      a corporation in good standing under the laws of the State of New York
      with full corporate power and authority to own its properties and to
      conduct its business as now conducted. GMC is duly qualified to do
      business as a foreign corporation in good standing in all jurisdictions
      where the nature of its assets or business requires such qualification and
      such jurisdictions are listed in Part A of the Schedule except where the
      failure to be so qualified or in good standing would not have a material
      adverse effect on the business, properties, assets, results of operations
      or condition (financial or otherwise) of GMC. GMC owns, directly or
      indirectly, all of the outstanding capital stock of General Microwave
      Foreign Sales Corporation, GMC Associates, Inc., Micro-EL Patent
      Corporation, General Microwave Israel (1987) Ltd. and General Microwave
      Israel Corp. and 97% of the outstanding Common Stock and all of the
      outstanding preferred stock of General Microcircuits Corporation
      (collectively the "Subsidiaries"). GMC does not own, directly or
      indirectly, shares of capital stock in any corporation other than the
      Subsidiaries. The Subsidiaries are duly incorporated and validly existing
      as corporations in good standing under the laws of the jurisdiction of
      their respective organization with full corporate power and authority to
      own their properties and to conduct their businesses as now conducted. The
      Subsidiaries are duly qualified to do business as a foreign corporation in
      good standing in all jurisdictions where the nature of their assets or
      business requires such qualification and such jurisdictions are listed in
      Part A of the Schedule except where the failure to be so qualified or in
      good standing would not have a material adverse effect on the business,
      properties, assets, results of operations or condition (financial or
      otherwise) of any such Subsidiary. The Certificate of Incorporation and
      the By-laws of GMC and of each of the Subsidiaries, heretofore delivered
      by GMC to Acquisition, are complete and correct and contain all amendments
      thereto.
 
(b)   Authority of GMC.  GMC has the corporate power to enter into this
      Agreement and, subject to the approval of the Merger by its shareholders,
      to carry out the transactions contemplated hereby. The execution and
      delivery of this Agreement and the consummation of the Merger and the
      transactions contemplated hereby have been duly approved and authorized by
      the Board of Directors of GMC and the Board
 
                                       A-5
<PAGE>   173
 
      of Directors of GMC has recommended that holders of GMC Shares adopt this
      Agreement and approve the Merger; except for the adoption of this
      Agreement and approval of the Merger by its shareholders, no other
      corporate acts or proceedings on the part of GMC are necessary to
      authorize this Agreement or the consummation of the transactions
      contemplated hereby. Subject to the approval of the Merger by its
      shareholders, this Agreement constitutes the valid and legally binding
      obligation of GMC enforceable against GMC in accordance with its terms.
      Except as set forth in Part B of the Schedule, the execution and delivery
      of this Agreement by GMC does not, and the consummation of the
      transactions contemplated hereby will not, violate or constitute a default
      under (i) any provision of the Certificate of Incorporation or By-laws of
      GMC, (ii) any provision of (or result in acceleration of any obligation
      under) any mortgage, note, lien, lease, agreement, instrument, arbitration
      award, judgment or decree to which GMC or any of the Subsidiaries is a
      party or by which GMC or any of the Subsidiaries is bound or to which any
      property of GMC or any of the Subsidiaries is subject or (iii) any laws of
      the United States or any state or jurisdiction in which GMC or any of the
      Subsidiaries conducts business.
 
(c)   Capitalization.  The authorized capital stock of GMC consists of 5,000,000
      shares of Common Stock. As of the date hereof, 1,678,011shares of Common
      Stock of GMC are validly issued and outstanding, fully paid and
      nonassessable, and 476,108 GMC Shares are held in the treasury of GMC. As
      of the date hereof, 88,000 GMC shares are subject to outstanding Options
      under the 1990 Stock Option Plan and 30,000 GMC Shares are reserved under
      the 1997 Non-Employee Director Stock Option Plan for issuance pursuant to
      options heretofore granted thereunder and 3,372 Shares are reserved for
      issuance pursuant to the Employee Stock Purchase Plan. As of the date
      hereof, GMC has no commitments to issue or sell any Shares of its capital
      stock or any securities or obligations convertible into or exchangeable
      for, or giving any person any right to subscribe for or acquire from GMC
      any shares of capital stock of GMC and no securities or obligations
      evidencing any such rights are outstanding, except pursuant to the
      outstanding options and warrants described above.
 
(d)   Consents, etc.  No consent, authorization, order or approval of, or filing
      or recording with, any governmental commission, board or other regulatory
      body is required for or in connection with the execution and delivery of
      this Agreement by GMC and the consummation by GMC of the transactions
      contemplated hereby, except for (i) the filing of a Form S-4 Registration
      Statement (the "Registration Statement") with respect to the warrants and
      shares of Herley Common Stock underlying the warrants with the Securities
      and Exchange Commission (the "SEC") in accordance with the Securities Act
      of 1933, as amended (the "Securities Act"), (ii) the filing of the
      Certificate of Merger with the Secretary, (iii) the filing of a joint
      proxy statement (the "Proxy Statement") with Herley with the SEC in
      accordance with the Securities Exchange Act of 1934, as amended (the
      "Exchange Act"), (iv) the filing of a Current Report on Form 8-K with the
      SEC, (v) such consents, approvals, orders, authorizations, registrations,
      declarations and filings as may be required under applicable federal and
      state securities laws and the laws of any foreign country and (vi) such
      filings as may be required to be made with respect to the transfer of
      title to real property owned by GMC.
 
(e)   Financial Statements.  GMC has previously furnished Acquisition with a
      true and complete copy of the audited consolidated balance sheet of GMC as
      of February 28, 1997 and 1998 and the related audited statements of
      consolidated income and retained earnings and of consolidated changes in
      financial position for the fiscal years
 
                                       A-6
<PAGE>   174
 
      then ended including the notes thereto, all reported on by KPMG Peat
      Marwick LLP, independent certified public accountants, and the unaudited
      consolidated balance sheet of GMC as of May 30, 1998 and the related
      unaudited statements of consolidated income and retained earnings and of
      consolidated changes in financial position for the three months then ended
      (collectively the "GMC Financial Statements"). The GMC Financial
      Statements present fairly the consolidated revenues of GMC and its
      subsidiaries for the periods then ended in conformity with generally
      accepted accounting principles applied on a consistent basis.
 
      GMC and the Subsidiaries have no material liabilities, contingent or
      otherwise, (including liabilities for taxes) other than (i) liabilities
      which will be shown or reflected in the unaudited financial statements
      referred to in Section 5.1(e) hereof (the "August Financials"), (ii)
      liabilities incurred in the ordinary course of business since February 28,
      1998, and (iii) those liabilities described in part E of the Schedule.
 
(f)   Absence of Certain Changes or Events.  Except as set forth in part F of
      the Schedule, since February 28, 1998, there has not been any material
      adverse change in the financial condition, properties, business or results
      of operations of GMC and the Subsidiaries and since May 30, 1998 there has
      not been (i) any change in the authorized, issued or outstanding capital
      stock or material change in the funded debt of GMC and the Subsidiaries on
      a consolidated basis, other than changes in the outstanding capital stock
      due to exercise of options under the Option Plans and outstanding warrants
      and other than changes due to payments in a accordance with the terms of
      such debt; (ii) any declaration, setting aside or payment of any dividend
      on, or distribution in respect of, any shares of the capital stock of GMC
      or the acquisition for value by GMC or any of the Subsidiaries of any
      shares of capital stock of GMC; or (iii) any grant by GMC of any warrant,
      option or right to acquire any GMC Shares or other securities whatsoever.
      Neither GMC nor the Subsidiaries is currently in default on any
      installment or installments on indebtedness for borrowed money, or on any
      rental on any long-term lease.
 
(g)   Governmental Authorization and Compliance with Laws.  The businesses of
      GMC and the Subsidiaries have been operated in compliance in all material
      respects with all laws, ordinances, regulations and orders of all
      governmental entities. GMC and the Subsidiaries have all material permits,
      certificates, licenses, approvals and other authorizations required in
      connection with the operation of their businesses, a complete list of
      which are set forth in Part G of the Schedule.
 
(h)   Tax Matters.
 
      (A)   Except as disclosed in Part E of the Schedule: The amounts shown as
            tax liabilities on the consolidated balance sheet of GMC as of May
            30, 1998 included in the GMC Financial Statements will be sufficient
            for the payment of all federal, state, county, local and foreign
            Taxes (as hereinafter defined) of GMC and the Subsidiaries, whether
            or not disputed, which were properly accruable at that date. There
            are no agreements by GMC or any of the Subsidiaries for the
            extension of the time for assessment of any Taxes. Neither the
            Internal Revenue Service (the "IRS") nor any other taxing authority
            is now asserting, or to the knowledge of GMC threatening to assert,
            against GMC or any of the Subsidiaries any claim for additional
            Taxes, nor to GMC's knowledge is the IRS or any other taxing
            authority auditing any tax return filed by GMC or any of the
            Subsidiaries.

            estimates, information returns and statements ("Returns") required
            to be filed or sent by or with respect to them in respect of any
            Taxes;
 
      (C)   As of the time of filing, such Returns were (and, as to Returns not

            all material respects;
 
      (D)   GMC and the Subsidiaries have timely paid or provided for (and until

            are due and payable;
 
      (E)   GMC and the Subsidiaries have complied in all material respects with
            all applicable laws, rules and regulations relating to the payment

            amounts required to be so withheld and paid over under all
            applicable laws;
 
      (F)   None of GMC or the Subsidiaries has filed a consent pursuant to
            Section 341(f) of the Internal Revenue Code of 1986 (the "Code") or
            agreed to have Section 341(f)(2) of the Code apply to any
            disposition of a subsection (f) asset (as such term is defined in
            Section 341(f)(4) of the Code) owned by GMC or any of the
            Subsidiaries;
 
      (G)   No property used by GMC or the Subsidiaries is property that GMC or
            any such Subsidiary is or will be required to treat as being owned
            by another person pursuant to the provisions of Section 168(f)(8) of
            the Internal Revenue Code of 1954 as it existed prior to the
            enactment of the Tax Reform Act of 1986 or is "tax-exempt use
            property" within the meaning of Section 168 (h) or the Code; and
 
      (H)   None of GMC or the Subsidiaries is required to include in income any
            adjustment pursuant to Section 481(a) of the Code by reason of
            voluntary change in accounting method initiated by GMC, or for any
            other reason, nor does GMC have any knowledge that the Internal
            Revenue Service has proposed any such adjustment or change in
            accounting method.
 
            For purposes of this Agreement, "Taxes" shall mean all taxes,

            (domestic or foreign) upon GMC or any of the Subsidiaries.
 
(i)   Title to Properties; Absence of Liens and Encumbrances, etc.  Except for
      leased properties, GMC and the Subsidiaries have good and marketable title
      to all of their tangible properties and assets, real, personal and mixed,
      used in their business, including without limitation those referred to in
      the balance sheet as of May 30, 1998 referred to in paragraph (e) of this
      Section 4.1 (other than properties or assets disposed of in the ordinary
      course of business since the date of such balance sheet), free and clear

      requested by Acquisition, of:
 
      (i)  all sales contracts of GMC or any of the Subsidiaries having a sales
           price of $50,000 or more or not to be performed within one year
           regardless of amount and all purchase orders having a purchase price
           of $25,000 or more;
 
      (ii) all other contracts of GMC or any of the Subsidiaries (other than
           sales contracts and purchase orders), leases, mortgages, indentures,
           promissory notes, deeds, loan or credit agreements, or similar
           instruments involving amounts in excess of $25,000 or more or not to
           be performed within one year regardless of amount;
 
      (iii)all pension, profit-sharing or employee benefit plans, employment
           contracts, contracts with unions and other agreements relating to
           employees of GMC or any of the Subsidiaries;
 
      (iv) all GMC and the Subsidiaries' policies of insurance issued during the
           past five years; and

           will contain a true and complete list of all of the above described
           contracts and leases. Except as set forth in Part J of the Schedule,
           none of GMC or the Subsidiaries is or will be in default, and no
           event has occurred or will have occurred which (whether with or
           without notice, lapse of time or the happening or occurrence of any
           other event) would constitute a default under any of the above
           described contracts and leases, and all such contracts and leases are
           valid and legally binding.
 
(k)   Litigation.  Except as set forth in Part K of the Schedule, when delivered
      to Acquisition and Herley, there is and will be no claim, action, suit or
      proceeding in or before any court or administrative or regulatory agency

      Subsidiaries or any of their properties.
 
(l)   Patents, Copyrights, Trademarks, etc.  GMC and the Subsidiaries have good
      and marketable title to all patents, patent applications, copyrights,

      information, technology, inventions, discoveries, improvements, processes,
      know-how, formulae, drawings, specifications, production data, trade
      secrets and computer software and programs, and licenses thereof, which
      are necessary for the operation of their businesses as presently conducted
      and as proposed to be conducted, a true and complete list of which will be
      included in Part L of the Schedule. Except as set forth in Part L of the
      Schedule, there are and will be no claims or proceedings threatened or

      of the Subsidiaries is infringing any such intellectual property rights of
      any other person.
 
(m)   Employee Benefit Plans.  Other than those set forth in Part M of the
      Schedule, GMC and the Subsidiaries do not maintain, administer or
      contribute to any bonus, profitsharing, pension, retirement, stock
      purchase, stock option, deferred compensation, hospitalization, medical,
      life insurance, disability, severance pay or other benefit plan
      arrangement or program, including, but not limited to, any employee
      benefit
 
                                       A-9

      plan within the meaning of Section 3(3) of the Employee Retirement Income
      Security Act of 1974, as amended ("ERISA"), covering any of GMC's or the
      Subsidiaries' employees (the "Plans").
 
      GMC has furnished or will furnish Acquisition with (i) complete and
      accurate copies of all documents comprising or pertaining to each Plan,
      including each amendment and any trust agreement, insurance contract, or
      other arrangement for the funding of benefits under such Plan, (ii) copies
      of all determination letters or private rulings issued by the IRS with
      respect to each Plan and copies of all applications and requests filed
      with the IRS for such determinations or rulings, (iii) a copy of the three
      (3) most recent annual reports (Form 5500) for each Plan and (iv) a copy
      of the most recent summary plan description ("SPD"), and all summaries of
      material modifications to such SPD, for each Plan.
 
      Each Plan is, and at all times since its inception has been, in compliance
      in all material respects with all the provisions of ERISA applicable to
      such Plan, and with all other laws, rules and regulations applicable to
      such Plan.
 
      Each Plan that is intended to meet the requirements for qualification
      under Section 401(a) of the Internal Revenue Code of 1986, as amended (the
      "Code") or that is intended to qualify for special tax treatment under any
      other provision of the Code, is, and at all times since its inception has
      been, in compliance with all conditions necessary for such Plan to so
      qualify. GMC is not aware of any fact that might cause any such Plan to
      lose its qualified status.
 
      No prohibited transaction within the meaning of the applicable provisions
      to ERISA and the Code have occurred with respect to any Plan. No
      transaction has occurred with respect to any Plan that has resulted in, or
      could result in, liability for GMC or any of the Subsidiaries (or for any
      successor to GMC or any of the Subsidiaries) under Title IV of ERISA.
 
      GMC, the Subsidiaries and each fiduciary for each of the Plans is in
      compliance with the terms of each Plan, and with the requirements and
      duties of any and all laws, statutes, orders, decrees, rules and
      regulations, including but not limited to ERISA and the Code, applicable
      to each Plan. All contributions and other payments required to be made by
      GMC or any of the Subsidiaries under or with respect to each Plan under
      the terms of such Plan, ERISA (including Part 3 of Subtitle B of Title I
      of ERISA), the Code (including Code Section 412), or otherwise have been
      made or accruals adequate for such purposes as of the date of the most
      recent financial statements of GMC have been provided therefor and
      reflected in said financial statements in accordance with GAAP.
 
      There is no pending, or to the best of the knowledge of GMC, threatened,
      legal action, proceedings or investigations against GMC, the Subsidiaries
      or any Plan, other than routine claims for benefits, which could result in
      liability being imposed upon any of the Plans or upon GMC or any of the
      Subsidiaries with respect to any of the Plans and there is no basis for
      any such legal action or proceeding.
 
      The actuarial present value of accrued benefits (both vested and unvested)
      of each of the Plans does not exceed the assets of such Plans based upon
      actuarial assumptions which are reasonable in light of the experience of
      each such Plan.
 
      Except as set forth in Part M of the Schedule, there are no agreements
      between GMC or any of the Subsidiaries and any labor union and GMC and the
      Subsidiaries
 
                                      A-10

      are not, and have never been a participating employer in any multiemployer
      plan, as such term is defined in Section 3(37) of ERISA, or in any
      multiple employer plan described in Section 413(c) of the Code. To the
      extent that GMC or either of the Subsidiaries is or has been a
      participating employer in any multiemployer plan (as so defined), none of
      GMC or the Subsidiaries is now, or would upon withdrawal therefrom become,
      liable for any withdrawal liability to or in respect of such multiemployer
      plan.
 
      The execution and delivery of this Agreement and Plan of Merger and the
      consummation of the transactions contemplated hereby will not result in
      any payment (whether of severance pay or otherwise) becoming due from any
      of the Plans, or from GMC or any of the Subsidiaries with respect to any
      of the Plans, to any individual, or result in the vesting, acceleration or
      payment or increases in the amount of any benefit payable under any of the
      Plans to any individual.
 
(n)   Finder's Fee.  No brokers or finders were employed by GMC or any of the
      Subsidiaries in connection with any of the transactions contemplated by
      this Agreement and no fee will be payable by GMC, Herley or Acquisition
      with respect to the transactions contemplated hereby by reason of any
      agreement between GMC or any of the Subsidiaries with any finder,
      including Franco, Lewis & Company, Inc.
 
(o)   No Failure to Disclose.  GMC has not failed to disclose to Acquisition any
      agreement, arrangement, event or occurrence, or threatened or anticipated
      event or occurrence known to GMC, which would or might reasonably be
      deemed to have a material and adverse effect on the financial condition,
      the business or the operations of GMC or any of the Subsidiaries.
 
(p)   Proxy Statement.  The information concerning GMC and the Subsidiaries and
      the Merger contained in the Proxy Statement (i) will include all
      statements of material facts which are required to be stated therein, and
      (ii) will not include any untrue statement of a material fact or omit to
      state any material fact required to be stated therein or necessary to make
      the statements therein not misleading.
 
(q)   Insider Interests.  No officer or director of GMC or any of the
      Subsidiaries has any agreement with GMC or any of the Subsidiaries or any
      interest in any property, real, personal or mixed, tangible or intangible
      (including, without limitation, patents, patent applications, trademarks,
      trade names or other intellectual property), used in or pertaining to the
      business of GMC or the Subsidiaries except as a shareholder or employee
      and except as set forth in Part Q of the Schedule.
 
(r)   Labor Controversies.  Except as set forth in Part R of the Schedule, there
      are no controversies between GMC or any of the Subsidiaries and any
      employees of GMC or the Subsidiaries or any unresolved labor union
      grievances or unfair labor practices or labor arbitration proceedings
      pending or threatened relating to GMC or the Subsidiaries and there are
      not any organizational efforts presently being made or threatened
      involving any of GMC's or any of the Subsidiaries' employees. None of GMC
      or the subsidiaries has received notice of any claim that it has not
      complied with any laws relating to the employment of labor, including any
      provisions thereof relating to wages, hours, collective bargaining, the
      payment of social security and similar taxes, equal employment
      opportunity, employment discrimination or employment safety, or that it is
      liable for any arrears of wages or any taxes or penalties for failure to
      comply with any of the foregoing.

(s)   Use of Real Property.  The real properties owned and leased by GMC and the
      Subsidiaries are used and operated in compliance and conformity in all
      material respects with all applicable leases, contracts, commitments,
      licenses and permits. None of GMC or the Subsidiaries has received notice
      of violation of any applicable zoning or building regulation, ordinance or
      other law, order, regulation or requirement relating to the operations of
      GMC or the Subsidiaries and to GMC's knowledge there is no such violation.
      All plants and other buildings which are owned or leased by GMC or any of
      the Subsidiaries conform in all material respects with all applicable
      ordinances, codes, regulations and requirements, and no law or regulation
      presently in effect or condition precludes or restricts continuation of
      the present use of such properties.
 
(t)   Accounts Receivable.  The accounts receivable which will be reflected on
      the unaudited consolidated balance sheet of GMC included in the August
      Financials, and all accounts receivable of GMC and the Subsidiaries
      arising since the date of such balance sheet arose from bona fide
      transactions in the ordinary course of business, and the materials or
      services involved have been provided to the account obligor, and, except
      as contemplated by the relevant contract, no further materials or services
      are required to be provided in order to complete the sales and to entitle
      GMC or the Subsidiaries, or their assignees, to collect the accounts
      receivable in full. Except as set forth in Part T of the Schedule, no such
      account receivable has been assigned or pledged to any other person, firm
      or corporation, and no defense or setoff to any such account has been
      asserted by the obligor.

      Schedule:
 
      (i)  GMC and the Subsidiaries are in compliance with all environmental
           laws, regulations, permits and orders applicable to them, and with
           all laws, regulations, permits and orders governing or relating to
           asbestos removal or abatement.
 
      (ii) Except for temporary storage on premises pending arrangement for
           removal, none of GMC or the Subsidiaries has transported, stored,
           treated or disposed of, nor has it allowed or arranged for any third
           parties to transport, store, treat or dispose of, hazardous
           substances or other waste to or at any location other than a site
           lawfully permitted to receive such hazardous substances or other
           waste for such purposes; and GMC and the Subsidiaries have not
           performed, arranged for or allowed by any method or procedure such
           transportation, storage, treatment or disposal in contravention of
           any laws or regulations. None of GMC or the Subsidiaries has
           disposed, or allowed or arranged for any third parties to dispose, of
           hazardous substances or other waste upon property owned or leased by
           it.
 
      (iii)There has not occurred, nor is there presently occurring, a Release
           of any hazardous substance on, into or beneath the surface of any
           parcel of real property in which GMC or any of the Subsidiaries has
           or has had an ownership interest or any leasehold interest. For
           purposes of this Section the term "Release" shall mean releasing,
           spilling, leaking, pumping, pouring, emitting, emptying, discharging,
           injecting, escaping, leaching, disposing or dumping.

           hazardous substance or other waste to or at a site which, pursuant to
           the U.S. Comprehensive Environmental Response, Compensation and
           Liability Act of 1980, as amended ("CERCLA") or any similar state
           law, (A) has been placed on the National Priorities List or its state
           equivalent, or (B) the Environmental Protection Agency or the
           relevant state agency has proposed or is proposing to place on the
           National Priorities List or its state equivalent. None of GMC or the
           Subsidiaries has received notice, or has knowledge, of any facts
           which could give rise to any notice that GMC or any of the
           Subsidiaries is a potentially responsible party for a federal or
           state environmental cleanup site or for corrective action under
           CERCLA or any other applicable law or regulation. None of GMC or the
           Subsidiaries has submitted nor was required to submit any notice
           pursuant to Section 103(c) of CERCLA. None of GMC or the Subsidiaries
           has received any written or oral request for information in
           connection with any federal or state environmental cleanup site or
           has undertaken (or been requested to undertake) any response or
           remedial actions or cleanup actions of any kind at the request of any
           federal, state or local governmental entity, or at the request of any
           other person or entity.
 
      (v)  There are no laws, regulations, ordinances, licenses, permits or
           orders relating to environmental or worker safety matters requiring
           any work, repairs, construction or capital expenditures with respect
           to the assets or properties of GMC or any of the Subsidiaries.
 
      (vi) Part V of the Schedule identifies (A) all environmental audits,
           assessments or occupational health studies undertaken by GMC or any

           of the Subsidiaries; (B) the results of any groundwater, soil, air or

           U.S.C. Sections 651 et seq.).
 
4.2 Representations and Warranties by Acquisition and Herley.  Each of
    Acquisition and Herley jointly and severally represents and warrants to, and
    agrees with GMC as follows:
 
(a)   Organization of Acquisition and Herley.  Acquisition and Herley are
      corporations duly organized, validly existing and in good standing under
      the laws of the States of New York and Delaware, respectively and
      Acquisition and Herley and each of its subsidiaries is duly qualified to
      do business and is in good standing in each jurisdiction in which the
      character of its properties owned or leased, or the nature of its
      activities makes such qualification necessary, except where the failure to
      be so qualified or in good standing would not have a material adverse
      effect on the business, properties, assets, results of operations or
      condition (financial or otherwise) of Herley and its subsidiaries taken as
      a whole.
 
(b)   Authority of Acquisition and Herley.  Acquisition and Herley have the

                                                                          Shares
 
THIS IS TO CERTIFY that, for value received,                is entitled, subject
to the terms and conditions set forth, at or before 5 P.M., New York City Time,
on              , 2001, but not thereafter, to purchase the number of shares set
forth above of Common Stock, par value $.10 per shares (the "Common Stock"), of
HERLEY INDUSTRIES, INC., a Delaware corporation (the "Corporation"), from the
Corporation at a purchase price per share of (i) $14.40 if and to the extent
this Warrant is exercised, in whole or in part on or before January 11, 1999, or
(ii) $15.60 if and to the extent this Warrant is exercised, in whole or in part
after January 11, 1999 but during the period this Warrant remains in force,
subject in all cases to adjustment as provided in Section 3 hereof, and to
receive a certificate or certificates representing the shares of Common Stock so
purchased, upon presentation and surrender to the Corporation of this Warrant,
with the form of subscription attached hereto duly executed, and accompanied by
payment of the purchase price of each share purchased either in cash or by
certified or bank cashier's check payable to the order of the Corporation.
 
1.    The Corporation covenants and agrees that all shares may be delivered upon
      the exercise of this Warrant and will, upon delivery, be fully paid and
      non-assessable, and, without limiting the generality of the foregoing, the
      Corporation covenants and agrees that it will from time to time take all
      such action as may be requisite to assure that the par value per share of
      the Common Stock is at all times equal to or less than the then current
      Warrant purchase price per share of the Common Stock issuable upon
      exercise of this Warrant.
 
2.    The rights represented by this Warrant are exercisable at the option of
      the holder hereof in whole at any time, or in part from time to time,
      within the period above specified at the prices specified in Section 1
      hereof . In case of the purchase of less than all the shares as to which
      this Warrant is exercisable, the Corporation shall cancel this Warrant
      upon the surrender hereof and shall execute and deliver a new Warrant of
      like tenor for the balance of the shares purchasable hereunder.
 
3.    The price per share at which shares of Common Stock may be purchased
      hereunder, and the number of such shares to be purchased upon exercise
      hereof, are subject to change or adjustment as follows:
 
      (A)   In case the Corporation shall, while this Warrant remains
            unexercised, in whole or in part, and in force, effect a
            recapitalization of such character that the shares of Common Stock
            purchasable hereunder shall be changed into or become exchangeable
            for a larger or smaller number of shares, then, after the
<PAGE>   199
 
            date of record for effecting such recapitalization, the number of
            shares of Common Stock which the holder hereof shall be entitled to
            purchase hereunder shall be increased or decreased, as the case may
            be, in direct proportion to the increase or decrease in the number
            of shares of Common Stock by reason of such recapitalization, and
            the purchase price hereunder per share of such recapitalized Common
            Stock shall, in the case of an increase in the number of such
            shares, be proportionately reduced, and in the case of a decrease in
            the number of such shares, shall be proportionately increased. For
            the purpose of this subsection (A), a stock dividend, stock split-up
            or reverse split shall be considered as a recapitalization and as an
            exchange for a larger or smaller number of shares, as the case may
            be.
 
      (B)   In the case of any consolidation of the Corporation with, or merger
            of the Corporation into, any other corporation, or in case of any
            sale or conveyance of all or substantially all of the assets of the
            Corporation in connection with a plan of complete liquidation of the
            Corporation, then, as a condition of such consolidation, merger or
            sale or conveyance, adequate provision shall be made whereby the
            holder hereof shall thereafter have the right to purchase and
            receive, upon the basis and upon the terms and conditions specified
            in this Warrant and in lieu of shares of Common Stock immediately
            theretofore purchasable and receivable upon the exercise of the
            rights represented hereby, such shares of stock or securities as may
            be issued in connection with such consolidation, merger or sale or
            conveyance with respect to or in exchange for the number of
            outstanding shares of Common Stock immediately therefore purchasable
            and receivable upon the exercise of the rights represented hereby
            had such consolidation, merger or sale or conveyance not taken
            place, and in any such case appropriate provision shall be made with
            respect to the rights and interests of the holder of this Warrant to
            the end that the provisions hereof shall be applicable as nearly as
            may be in relation to any shares of stock or securities thereafter
            deliverable upon the exercise hereof.
 
      (C)   In case the Corporation shall, while this Warrant remains
            unexercised, in whole or in part, and in force, issue (otherwise
            than by stock dividend or stock split-up or reverse split) or sell
            shares of its Common Stock (hereinafter referred to as "Additional
            Shares") for a consideration per share (before deduction of expenses
            or commissions or underwriting discounts or allowances in connection
            therewith) less than the current market price per share of Common
            Stock on the record date of issuance or grant, then, after the date
            of such issuance or sale, the purchase price hereunder per share
            shall be reduced to a price determined by dividing (1) an amount
            equal to (a) the total number of shares of Common Stock outstanding
            immediately prior to the time of such issuance or sale multiplied by
            such purchase price hereunder per share, plus (b) the consideration
            (before deduction of expenses or commissions or underwriting
            discounts or allowances in connection therewith), if any, received
            by the Corporation upon such issuance or sale, by (2) the total
            number of shares of Common Stock outstanding after the date of the
            issuance or sale of such Additional Shares, and the number of shares
            of Common Stock which the holder hereof shall be entitled to
            purchase hereunder at each such adjusted purchase price per share,
            at the time such adjusted purchase price per shall be in effect,
            shall be the number of whole shares of Common Stock obtained by
            multiplying such purchase price hereunder per share before such
            adjustment, by
<PAGE>   200
 
            the number of shares of Common Stock purchasable upon the exercise
            of this Warrant immediately before such adjustment, and dividing the
            product so obtained by such adjusted purchase price per share;
            provided, however, that no such adjustment of the purchase price
            hereunder per share or the number of shares for which this Warrant
            may be exercised shall be made upon the issuance or sale by the
            Corporation of not more than 5,039,868 Additional Shares reserved
            for issuance upon exercise of stock options or warrants.
 
      (D)   In case the Corporation shall, while this Warrant remains
            unexercised in whole or in part, and in force, issue or grant any
            rights to subscribe for or to purchase, or any option (other than
            the employee stock options referred to in subsection (C) above) for
            the purchase of (i) Common Stock or (ii) any indebtedness or shares
            of stock convertible into or exchangeable for Common Stock
            (indebtedness or shares of stock convertible into or exchangeable
            for Common Stock being hereinafter referred to as "Convertible
            Securities"), or issue or sell Convertible Securities and the price
            per share for which Common Stock is issuable upon the exercise of
            such rights or options or upon conversion or exchange of such
            Convertible Securities at the time such Convertible Securities first
            become convertible or exchangeable (determined by dividing (1) in
            the case of an issuance or grant of any such rights or options, the
            total amount, if any, received or receivable by the Corporation as
            consideration for the issuance or grant of such rights or options,
            plus the minimum aggregate amount of additional consideration
            payable to the Corporation upon exercise of such rights or options,
            plus, in the case of such Convertible Securities, in the minimum
            aggregate amount of additional consideration, if any, payable to the
            Corporation upon the conversion or exchange of such Convertible
            Securities at the time such Convertible Securities first become
            convertible or exchangeable, or (2) in the case of an issuance or
            sale of Convertible Securities other than where the same or issuable
            upon the exercise of any such rights or options, the total amount,
            if any, received or receivable by the Corporation as consideration
            for the issuance or sale of such Convertible Securities, plus the
            minimum aggregate amount of additional consideration, if any,
            payable to the Corporation upon the conversion or exchange of such
            Convertible Securities at the time such Convertible Securities first
            become convertible or exchangeable, by, in either such case, (3) the
            total maximum number of shares of Common Stock issuable upon the
            exercise of such rights or options or upon the conversion or
            exchange of such Convertible Securities at the time such Convertible
            Securities first become convertible or exchangeable) shall be less
            than the current market price per share of Common Stock on the
            record date of grant, then the total maximum number of shares of
            Common Stock issuable upon the exercise of such rights or options or
            upon conversion or exchange of the total maximum amount of such
            Convertible Securities at the time such Convertible Securities first
            become convertible or exchangeable, shall (as of the date of the
            issuance or grant of such rights or options or, in the case of the
            issuance or sale of Convertible Securities other than where the same
            are issuable upon the exercise of rights or options, as of the date
            of such issuance or sale) be deemed to be outstanding and to have
            been issued for said price per share; provided that (i) no further
            adjustment of the purchase price shall be made upon the actual
            issuance of such Common Stock upon the exercise of such rights or
            options or upon the conversion or exchange of such Convertible
            Securities or upon the actual issuance of Convertible Securities
            where the same are issuable upon the
<PAGE>   201
 
            exercise of such rights or options, and (ii) rights or options
            issued or granted pro rata to shareholders without consideration and
            Convertible Securities issuable by way of dividend or other
            distribution to shareholders shall be deemed to have been issued or
            granted at the close of business on the date fixed for the
            determination of shareholders entitled to such rights, options or
            Convertible Securities and shall be deemed to have been issued
            without consideration; and (iii) if, in any case, the total maximum
            number of shares of Common Stock issued upon exercise of such rights
            or options or upon conversion or exchange of such Convertible
            Securities is not, in fact, issued and the right to exercise such
            right or option or to convert or exchange such Convertible
            Securities shall have expired or terminated, then, and in any such
            event, the purchase price, as adjusted, shall be appropriately
            readjusted at the time of such expiration or termination. In such
            case, each purchase price hereunder per share which is greater than
            the price per share for which Common Stock is issuable upon
            conversion or exchange of such rights or options or upon conversion
            or exchange of such Convertible Securities at the time such
            Convertible Securities first become convertible or exchangeable, as
            determined above in this subsection (D), shall thereupon be reduced
            to a price determined by dividing (1) an amount equal to (a) the
            total number of shares of Common Stock outstanding immediately prior
            to the time of the issuance or grant of such rights or options or
            the issuance or sale of such Convertible Securities multiplied by
            such purchase price hereunder per share, plus (b) the total amount,
            if any, received or receivable by the Corporation as consideration
            for such issuance or grant or such issuance or sale, plus the
            additional amounts referred to and more fully set forth in clauses
            (1) and (2) of the parenthetical material above in this subsection
            (D), whichever clause and whichever additional amounts may be
            applicable, by (2) the total number of shares of Common Stock
            outstanding after the date of such issuance or grant or such
            issuance or sale, and the number of shares of Common Stock which the
            holder hereof shall be entitled to purchase hereunder at such
            adjusted purchase price per share, at the time such adjusted
            purchase price per shall be in effect, shall be the number of whole
            shares of Common Stock obtained by multiplying such purchase price
            hereunder, per share, before such adjustment, by the number of
            shares of Common Stock purchasable upon the exercise of this Warrant
            immediately before such adjustment and dividing the product so
            obtained by such adjusted purchase price per share.
 
      (E)   For the purpose of subsections (C) and (D) above, in case the
            Corporation shall issue or sell Additional Shares, issue or grant
            any rights to subscribe for or to purchase, or any options for the
            purchase of (i) Common Stock or (ii) Convertible Securities, or
            issue or sell Convertible Securities for a consideration part of
            which shall be other than cash, the amount of the consideration
            received by the Corporation therefor shall be deemed to be the cash
            proceeds, if any, received by the Corporation plus the fair value of
            the consideration other than cash as determined by the Board of
            Directors of the Corporation in good faith, before deduction of
            commissions, underwriting discounts or allowances or other expenses
            paid or incurred by the Corporation for any underwriting of, or
            otherwise in connection with, such issuance, grant or sale.
<PAGE>   202
 
      (F)   Subject to the provisions of subsection (G) below, in case the
            Corporation shall, while this Warrant remains unexercised, in whole
            or in part, and in force, make any distribution of its assets to
            holders of Common Stock as a partial liquidating dividend, by way of
            return of capital or otherwise, then, after the date of record for
            determining shareholders entitled to such distribution, the holder
            hereof shall be entitled, upon exercise of this Warrant and purchase
            of any or all of the shares of Common Stock subject hereto, to
            receive the amount of such assets (or at the option of the
            Corporation, a sum equal to the value thereof at the time of such
            distribution to holders of Common Stock as such value is determined
            by the Board of Directors of the Corporation in good faith) which
            would have been payable to such holder had he been the holder of
            record of such shares of Common Stock on the record date for the
            determination of shareholders entitled to such distribution.
 
      (G)   Except as otherwise provided in subsection (B) above, in the case of
            any sales or conveyance of all or substantially all of the assets of
            the Corporation in connection with a plan of complete liquidation of
            the Corporation, in the case of the dissolution, liquidation or
            winding up of the Corporation, all rights under this Warrant shall
            terminate on a date fixed by the Corporation, such date so fixed to
            be not earlier than the date of the commencement of the proceedings
            for such dissolution, liquidation or winding-up and not later than
            thirty (30) days after such commencement date. Notice of such

            stock of the Corporation, then the Corporation shall given written
            notice thereof to the registered holder hereof not less than thirty
            (30) days prior to the date on which the books of the Corporation
            are closed or a record date fixed for the determination of

            date fixed with respect to such offer or subscription, and the right
            of the holder hereof to participate in such offer or subscription
            shall terminate if this Warrant shall not be exercised on or before
            the date of such closing of the books or such record date.
 
      (I)   Any adjustment pursuant to the foregoing provisions shall be made on
            the basis of the number of shares of Common Stock which the holder
            hereof would have been entitled to acquire by exercise of this
            Warrant immediately prior to the event giving rise to such
            adjustment and, as to the purchase price hereunder per share,
            whether or not in effect immediately prior to the time of such
            adjustment, on the basis of such purchase price immediately prior to
            the event giving rise to such adjustment. Whenever any such
            adjustment is required to be made, the Corporation shall forthwith
            determine the new number of shares of Common Stock which the holder
            shall be entitled to purchase hereunder and/or such new purchase
            price per share, and shall prepare, retain on file and transmit to
            the holder hereof within ten (10) days after such preparation a
            statement describing in reasonable detail the method used in
            calculating such adjustment(s).

      shareholders of the Corporation concurrently with the distribution thereof
      to such shareholders.
 
8.    Notices to be given to the holder of this Warrant shall be deemed to have

      satisfied by the Corporation without the expenditure of unreasonable time
      or expense.
 
10.   Anything to the contrary herein notwithstanding, this Warrant shall be
      callable by the Corporation, in whole or in part, at any time after
      twenty-one (21) months after the
<PAGE>   204

1998 by and between GMC Acquisition Corporation, a New York corporation
("GMCAC"), and                (the "Shareholder").

and Plan of Merger (the "Merger Agreement") pursuant to which GMC will be merged
with and into GMCAC on the terms and subject to the conditions contained in the
Merger Agreement; and
 
WHEREAS, as a condition to its willingness to enter into the Merger Agreement,
GMCAC has requested that the Shareholder signatories thereto grant to GMCAC

lawful agent, attorney and proxy of the Shareholder during the term of this
Agreement to vote in its sole discretion all of the shares of Common Stock of
GMC ("Common Stock") of which the Shareholder is the owner of record (the
"Shares") (including any and all Common Stock acquired by the Shareholder after
the date hereof or through the exercise or acceleration of options) in the
following manner for the following purposes: (i) to call one or more meetings of
the Shareholder of GMC in accordance with the By-Laws of GMC and applicable law
for the purpose of considering the transactions contemplated by the Merger
Agreement such that the Shareholder shall have the full opportunity to approve
the Merger Agreement and any and all amendments, modifications and waivers
thereof and the transactions contemplated thereby; (ii) in favor of the Merger
Agreement or any of the transactions contemplated by the Merger Agreement at any
Shareholders meetings of GMC held to consider the Merger Agreement (whether
annual or special and whether or not an adjourned meeting; (iii) against any
other proposal for any recapitalization, merger, sale of assets or other
business combination between GMC and any other person or entity other than GMCAC
or the taking of any action which would result in any of the conditions to
GMCAC's obligations under the Merger Agreement not being fulfilled; and (iv) as
otherwise necessary or appropriate to enable GMCAC to consummate the
transactions contemplated by the Merger Agreement and, in connection with such
purposes, to otherwise Act with respect to the Shares which the Shareholder is

pledge, hypothecate or otherwise dispose of the Shares until the date of
termination of this Agreement pursuant to Section 2 hereof.
 
5.  Specific Performance.  The parties hereto agree that the Shares are unique
and that money damages are an inadequate remedy for breach of this Agreement
because of the difficulty of ascertaining the amount of damage that will be

11.  Counterparts.  This Agreement may be executed in several counterparts, each

           Agreement are of a specialized and unique character and that a
           breach, or threatened breach of this Agreement by Mr. Rinkel, will

           of any provision of this Agreement shall in no way affect the right
           of that party to enforce that provision of any other time, no shall
           it affect the party's right to enforce any other provision of this
           Agreement. The waiver by any party of a breach of any provision of
           this Agreement shall not be taken or held to be a waiver of any
           subsequent breach of the provision or as a waiver of the provision
           itself.
 
      (j)  If it is determined that any provision of this Agreement is too broad
           or otherwise unenforceable for any reason, Mr. Rinkel expressly
           agrees that any court of competent jurisdiction may narrow the terms
           of the provision so as to render them enforceable according to their
           intent and purpose.

           or his estate any amounts payable to him which accrue after that

           perform the services required of him by this Agreement for any period

GMC Acquisition Corporation and terminating two (2) years thereafter.
 
3.  Duties and Extent of Services During Period of Employment.  During the term
of employment, Employee shall be employed on a full-time basis as an executive

Company under the direction of the Board of Directors and executive officers of
the Company to the best of his ability, shall perform all duties incident to his
offices on behalf of the Company and shall perform such other duties as may from

subsidiary corporations of the Company as may be selected by the Board of
Directors.
 
4.  Remuneration.  During the period of employment, Employee shall be entitled
to receive the following compensation for his services: A salary at the rate of

      Company.
 
(c)   During the period of employment, Employee shall be furnished with office

insurance policy during the disability period.
 
7.  Confidential Information.
 
(a)   In the course of Employee's employment by the Company, Employee will have
      access to and possession of valuable and important confidential or
      proprietary data or information of the Company and its operations.
      Employee will not during Employee's employment by the Company or at any
      time thereafter divulge or communicate to any person nor shall Employee
      direct any Company employee, representative or agent to divulge or
      communicate to any person or entity (other than to a person or entity
      bound by confidentiality obligations similar to those contained herein and
      other than as necessary in performing Employee's duties hereunder) or use
      to the detriment of the Company or for the benefit of any other person or
      entity, any of such confidential or proprietary data or information or
      make or remove any copies thereof, whether or not marked or otherwise
      identified as "confidential" or "secret." Employee shall take all
      reasonable precautions in handling the confidential or proprietary data or
      information within the Company to a strict need-to-know basis and shall
      comply with any and all security systems and measures adopted from time to
      time by the Company to protect the confidentiality of confidential or
      proprietary data or information.
 
(b)   The term "confidential or proprietary data or information" as used in this
      Agreement shall mean information not generally available to the public,
      including, without limitation, all database information, personnel
      information, financial information, customer lists, supplier lists, trade
      secrets, patented or proprietary information, forms,
<PAGE>   213
 
      information regarding operations, systems, services, know how, bid
      preparation, computer and any other processed or collated data, computer
      programs, pricing, marketing and advertising data.
 
(c)   Employee will at all times promptly disclose to the Company in such form
      and manner as the Company may reasonably require, any inventions,
      improvements or procedural or methodological innovations, programs,
      methods, forms, systems, services, designs, marketing ideas, products or
      processes (whether or not capable of being trademarked, copyrighted or
      patented) conceived or developed or created by Employee during or in
      connection with Employee's employment hereunder and which relate to the
      business of the Company ("Intellectual Property"). Employee agrees that
      all such Intellectual Property shall be "work-for-hire" and shall be the
      sole property of the Company. To the extent any such Intellectual Property
      does not constitute a "work-for-hire" under U.S. law, Employee hereby
      assigns to Company all right, title and interest in such Intellectual
      Property. Employee further agrees that Employee will execute such
      instruments and perform such acts as may reasonably be requested by the
      Company to effectuate such assignment and otherwise to transfer to and
      perfect in the Company all rights in such Intellectual Property.
 
(d)   All written materials, records and documents made by Employee or coming
      into Employee's possession during Employee's employment by the Company
      concerning any products, processes or equipment manufactured, used,
      developed, investigated, purchased, sold or considered by the Company or
      otherwise concerning the business or affairs of the Company shall be the
      sole property of the Company, and upon termination of Employee's
      employment by the Company, or upon request of the Company during
      Employee's employment by the Company, Employee shall promptly deliver the
      same to the Company. In addition, upon termination of Employee's
      employment by the Company, Employee will deliver to the Company all other
      Company property in Employee's possession or under Employee's control,
      including, but not limited to, financial statements, marketing and sales
      data, customer and supplier lists, database information and other
      documents, and any Company credit cards.
 
(e)   The Employee shall immediately disclose to the Company any information
      relating to business opportunities relating to the business of the
      Company, and/or its subsidiaries which may be offered or communicated to
      the Employee.
 
(f)   The provisions of this Section 7 shall survive the termination of this
      Employment Agreement.
 
8.  Termination.
 
(a)   The Company recognizes that, for the period during which Employee has been
      employed and/or associated with the Company, the Company has been
      intimately familiar with the ability, competence and judgment of Employee,
      which are acknowledged to be of the highest caliber. Accordingly, the
      Company and Employee agree that Employee's services hereunder may be
      terminated for "cause" by the Company only (i) for an act of fraud or
      embezzlement adversely affecting the financial interest of the Company,
      (ii) in the event that the Company places Employee on disability status
      pursuant to Section 6 hereof more than once during the term hereof, (iii)
      in the event of a conviction of the Employee for any felony, (iv) in the
      event of material breach by the Employee of the terms of this Agreement,
      following the receipt by the Employee of ten (10) days notice of such
      breach and the
<PAGE>   214
 
      Employee's failure to cure such breach within such grace period, (v) in
      the event of any willful breach by the Employee of this Agreement, or (vi)
      in the event that the Employee materially breaches any of his
      representations, warranties, covenants or agreements contained in the
      Agreement and Plan of Merger of even date herewith to be executed by the
      Company. This Agreement shall also terminate on the death of Employee.
 
(b)   If the Company terminates Employee's employment hereunder for any reason
      other than for "cause" as set forth in Section 8(a) hereof, Employee's
      compensation shall be paid to him as provided hereunder for the remainder
      of the term of this Agreement. If the Company terminates Employee's
      employment hereunder for "cause" as set forth in Section 9(a) hereof,
      Employee shall not be entitled to receive any further compensation
      hereunder which has not already been earned pursuant to the terms hereof.
      Employee and the Company acknowledge that the foregoing provisions of this
      paragraph 8(b) are reasonable and are based upon the facts and
      circumstances of the parties at the time of entering into this Agreement,
      and with due regard to future expectations.
 
9.  Consolidation or Merger.  In the event of any consolidation or merger of the
Company into or with any other corporation during the term of this Agreement, or
the sale of all or substantially all of the assets of the Company to another
corporation, person or entity during the term of this Agreement, such successor
corporation shall assume this Agreement and become obligated to perform all of
the terms and provisions hereof applicable to the Company, and Employee's
obligations hereunder shall continue in favor of such successor corporation.
 
10.  Notices.  Any notice to be given to the Company hereunder shall be deemed
sufficient if addressed to the Company in writing and delivered or mailed by
certified or registered mail to its offices at 10 Industry Drive, Lancaster, PA
17603, or such other address as the Company may hereafter designate, with a copy
to David H. Lieberman, Esq., Blau, Kramer, Wactlar & Lieberman, P.C., 100

hereunder shall be delivered or mailed by certified or registered mail to him
at:                or such other address as he may hereafter designate.
 
11.  Successors and Assigns.  This Agreement shall be binding upon and inure to
the benefit of the successors and assigns of the Company, and unless clearly
inapplicable, all references herein to the Company shall be deemed to include
any such successor. In addition, this Agreement shall be binding upon and inure
to the benefit of the Employee and his heirs, executors, legal representatives
and assigns; provided, however, that the obligations of Employee hereunder may
not be delegated without the prior written approval of the Board of Directors of
the Company.
 
12.  Amendments.  This Agreement may not be altered, modified, amended or
terminated except by a written instrument signed by each of the parties hereto.
 
13.  Prior Agreements Superseded.  This Agreement supersedes any employment or
consulting agreements, oral or written, entered into between Employee and GMC
and the Company prior to the date of this Agreement.
 
14.  Applicable Law.  This Agreement shall be governed by, construed and
enforced in accordance with the laws of the State of Delaware, without regard to
conflicts of laws.
<PAGE>   215
 
15.  Acknowledgment.  Employee acknowledges that he has carefully read this
Agreement and hereby represents and warrants to the Company that Employee's
entering into this Agreement, and the obligations and duties undertaken by
Employee hereunder, will not conflict with, constitute a breach of or otherwise
violate the terms of any other agreement to which Employee is a party and that
Employee is not required to obtain the consent of any person, firm, corporation
or other entity in order to enter into and perform his obligations under this
Agreement.
 
IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the
day and year first above written.

Agreement to provide that Acquisition will merge with and into GMC and GMC will
be the surviving corporation in the merger; and
 
WHEREAS, the parties to the Merger Agreement further desire to make certain
other amendments to the Merger Agreement.
 
NOW, THEREFORE, in consideration of the mutual agreements contained herein, the
parties hereto agree as follows:
 
SECTION 1.  Amendments.  The Merger Agreement is hereby amended as follows:
 
(a)   Section 1.1 is hereby amended and restated as follows:
 
      "1.1  Surviving Corporation.  At the Effective Time (as defined in Section
      1.3 hereof), Acquisition shall be merged with and into GMC upon the terms
      and conditions hereinafter set forth as permitted by and in accordance
      with the BCL. At the Effective Time, the identity and separate existence
      of Acquisition shall cease, and GMC shall succeed to all rights,
      privileges, powers, franchises, properties, assets, debts, liabilities and
      obligations of Acquisition in accordance with the BCL."
 
(b)   Section 1.3 is hereby amended and restated as follows:
 
      "1.3  Effective Time.  The Merger shall become effective when the
      Certificate of Merger is filed by the Secretary in accordance with the
      applicable provisions of the BCL (or at such later time specified as the
      effective time in the Certificate of Merger), which Certificate shall be
      submitted for filing as soon as practicable after all of the conditions
      set forth in Article VI are fulfilled or waived, provided that this
      Agreement has not been previously terminated pursuant to Section 7.1
      hereof. The date and time when the Merger shall become effective are
      herein referred to as the "Effective Time." The Effective Time shall be
      after January 1, 1999."
 
(c)   Section 1.4 is hereby amended and restated as follows:
 
      "1.4  Certificate of Incorporation.  The Certificate of Incorporation of

<PAGE>   217
 
      Incorporation of GMC. Simultaneously with the Effective Time, the GMC
      Certificate of Incorporation shall be amended to conform to the
      substantive provisions of the Certificate of Incorporation attached as
      Exhibit B to this Agreement."
 
(d)   Section 3.1 is hereby amended and restated as follows:
 
      "3.1  Effect of Merger.  At and after the Effective Time, the separate
      existence of Acquisition shall cease, the GMC Shares shall cease to exist
      (except as evidence of the right of the holder thereof to receive cash and
      warrants therefor in accordance with the terms hereof), subject to the
      rights of holders of Dissenting Shares referred to in Section 2.1(b)
      hereof, and all rights, privileges, powers and franchises, and all
      property, tangible and intangible, of Acquisition and of GMC shall
      transfer to, vest in and devolve on the Surviving Corporation without
      further act or deed. Confirmatory deeds, assignments, or similar
      instruments to evidence such transfer may be executed and delivered at any
      time in the name of GMC or Acquisition by GMC's last acting officers or by
      the appropriate officers of the Surviving Corporation. The Surviving
      Corporation shall be liable for all of the debts and obligations of
      Acquisition and GMC. Any existing claim, action or proceeding pending by
      or against Acquisition or GMC may be prosecuted to judgment as if the
      Merger had not taken place or, on motion of the Surviving Corporation, the
      Surviving Corporation may be substituted as a party, and any judgment
      against Acquisition or GMC shall constitute a lien on the property of the
      Surviving Corporation. The Merger shall not impair the rights of creditors
      or any liens on the property of either of the Constituent Corporations."
 
(e)   All references in the Merger Agreement to the Surviving Corporation
      following the effectiveness of the Merger shall be deemed to refer to GMC,
      rather than Acquisition.
 
(f)   Section 4.1 is hereby amended and restated as follows:
 
      "4.1  Representations and Warranties by GMC.  GMC represents and warrants
      to, and agrees with, Acquisition and Herley, subject to the exceptions set
      forth in the disclosure schedule (the "Schedule") to be delivered to
      Acquisition and Herley, as follows:"
 
(g)   All references to the Schedule in the Merger Agreement shall be construed
      to reflect that such Schedule was not attached to the Merger Agreement at
      the time of its execution and is not a part of, or an exhibit to, the
      Merger Agreement. Notwithstanding the foregoing, the Schedule and its
      contents shall be considered together with the Merger Agreement for the
      purpose of determining GMC's compliance with its representations,
      warranties and covenants contained in the Merger Agreement.
 
(h)   Section 5.2(g) is hereby amended to add the following:
 
      "The foregoing shall not be construed to prevent GMC's purchase of an
      officers and directors' liability insurance policy having a term of three
      years from the Effective Time and covering acts prior to the Effective
      Time."
 
(i)   Section 6.2(g) is hereby amended and restated as follows:
 
      "(g)  Cutoff Date.  The Merger shall in any event have been completed no
      later than January 8, 1999. This condition shall be a mutual condition."

                date hereof, Mr. Rinkel shall be a part-time consultant to the
                Corporation."
 
      (B)  Section 4(a) shall be amended and restated as follows:
 
           "4.  Compensation
 
                (a) As full compensation for his services under this Agreement,

                    at the rate of Sixty Thousand ($60,000.00) Dollars per year.
                    This compensation shall be payable in equal monthly
                    installments."
 
(k)   All references in the Exhibits to the Merger Agreement to the merger of
      GMC into Acquisition shall be deemed to refer to the merger of Acquisition
      into GMC, with GMC as the surviving corporation. All references in such
      Exhibits to the "Surviving Corporation" shall be deemed to refer to GMC.
 
  SECTION 2.  All capitalized terms used herein, unless otherwise defined
herein, are used herein as defined in the Merger Agreement. Except as expressly
provided herein, all terms and provisions of the Merger Agreement shall remain
in full force and effect.
 
  SECTION 3.  This Agreement may be executed in any number of counterparts, each
of which when so executed and delivered will be deemed an original, and such
counterparts together will constitute one instrument.
 
IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly
executed as of the date first above written.

The Board of Directors
General Microwave Corporation
5500 New Horizons Boulevard
Amityville, NY 11701
 
Ladies and Gentlemen:
 
You have requested our opinion as to the fairness from a financial point of view
to the holders of the outstanding shares of common stock (the "Common Stock") of
General Microwave Corporation, a New York corporation, (the "Company") of the
consideration to be received by such shareholders in connection with the
proposed merger of GMC Acquisition Corporation, a Delaware corporation,
("Acquisition"), a wholly owned subsidiary of Herley Industries, Inc., a
Delaware corporation, ("Herley"), with and into the Company (the "Proposed
Transaction") pursuant to the Agreement and Plan of Merger dated as of August
21, 1998 and as amended on November 12, 1998 among Herley, Acquisition, the
Company and certain stockholders of the Company (the "Agreement").
 
We understand that the terms of the Agreement provide, among other things, that
each issued and outstanding share of Common Stock shall be converted into the
right to receive $18 in cash plus a warrant to purchase one share of Herley
Common Stock at a purchase price of $14.40 per share on or before January 11,
1999 or $15.60 per share after January 11, 1999 for three years after the
effective time of the Merger (collectively, the "Warrants"), as more fully set
forth in the Agreement.
 
Franco, Lewis & Company, Inc. ("Franco, Lewis & Company") is regularly engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, strategic transactions, corporate restructurings, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. We will
receive a fee for rendering this opinion.
 
In the past, we have provided financial advisory services to the Company and
have received fees for rendering these services. In addition, Edmond D. Franco,
an executive officer and holder of a significant percentage of the common stock
of Franco, Lewis & Company, is a member of the Board of Directors of the
Company. Franco, Lewis & Company may in the future provide additional investment
banking or other financial advisory services to Herley.

In connection with our review of the Proposed Transaction, and in arriving at
our opinion, we have, among other things:
 
(i)   reviewed the publicly available consolidated financial statements of the
      Company for recent years and interim periods to date and certain other
      relevant financial and operating data of the Company made available to us
      from published sources and from the internal records of the Company;
 
(ii)  reviewed certain internal financial and operating information relating to
      the Company, including certain projections, prepared by the management of
      the Company;
 
(iii) discussed the business, financial condition and prospects of the Company
      with certain of its officers;
 
(iv)  reviewed the recent reported prices and trading activity for the common
      stock of the Company and compared such information and certain financial
      information for the Company with similar information for certain other
      companies engaged in businesses we consider comparable;
 
(v)   reviewed the financial terms, to the extent publicly available, of certain
      comparable merger and acquisition transactions;
 
(vi)  reviewed the Agreement;
 
(vii) performed such other analyses and examinations and considered such other
      information, financial studies, analyses and investigations and financial,
      economic and market data as we deemed relevant.
 
In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning the Company considered in
connection with our review of the Proposed Transaction, and we have not assumed
any responsibility for independent verification of such information. We have
assumed that there have been no material changes in the Company's assets,
financial condition, results of operations, business or prospects since the
respective dates of their last financial statements made available to us. We
have relied on advice of counsel and independent accountants to the Company as
to all legal and financial reporting matters with respect to the Company, the
Proposed Transaction and the Agreement, including the legal status and financial
reporting of litigation involving the Company. We have assumed that the Proposed
Transaction will be consummated in a manner that complies in all respects with
the applicable provisions of the Securities Act of 1933, as amended (the
"Securities Act"), the Securities Exchange Act of 1934, as amended, and all
other applicable federal and state statutes, rules and regulations.
 
We have not prepared any independent valuation or appraisal of any of the assets
or liabilities of the Company; nor have we conducted a physical inspection of
the properties and facilities of the Company. With respect to the financial
forecasts and projections made available to us and used in our analysis, we have
assumed that they reflect the best currently available estimates and judgments
of the expected future financial performance of the Company. For purposes of
this opinion, we have assumed that the Company is not a party to any pending
transactions, including external financings, recapitalizations or material
merger discussions, other than the Proposed Transaction and those activities
undertaken in the ordinary course of conducting its business. Our opinion is
necessarily based upon market, economic, financial and other conditions as they
exist and can be evaluated as of the date of this letter and any change in such
conditions would require a
 
                                       C-2
<PAGE>   223
 
reevaluation of this opinion. In addition, for purposes of this opinion and with
the approval of the Board of Directors of the Company, we have assumed that the
Warrants have no value.
 
It is understood that this letter is for the information of the Board of
Directors only and may not be used for any other purpose without our prior
written consent; provided, however, that this letter may be reproduced in full
in the Proxy Statement relating to the Proposed Transaction. This letter does
not constitute a recommendation to any stockholder as to how such stockholder
should vote on the Proposed Transaction. In furnishing this opinion, we do not
admit that we are experts within the meaning of the term "experts" as used in
the Securities Act and the rules and regulations promulgated thereunder, nor do
we admit that this opinion constitutes a report or valuation within the meaning
of Section 11 of the Securities Act.
 
Based upon and subject to the foregoing and after considering such other matters
as we deem relevant, we are of the opinion that as of the date hereof the
consideration to be received by the holders of the Company's Common Stock in the
Proposed Transaction is fair to such holders from a financial point of view. We
express no opinion, however, as to the adequacy or fairness of any consideration
received in the Proposed Transaction by Herley or any of its affiliates.
 
                                          Very truly yours,
 
                                          Franco, Lewis & Company, Inc.

                ANNEX D -- NEW YORK BUSINESS CORPORATION LAW --
                              SECTIONS 623 AND 910
 
623 PROCEDURE TO ENFORCE SHAREHOLDER'S RIGHT TO RECEIVE PAYMENT FOR SHARES.
 
(a)   A Shareholder intending to enforce his right under a section of this
      chapter to receive payment for his shares if the proposed corporate action
      referred to therein is taken shall file with the corporation, before the
      meeting of shareholders at which the action is submitted to a vote, or at
      such meeting but before the vote, written objection to the action. The
      objection shall include a notice of his election to dissent, his name and
      residence address, the number and classes of shares as to which he
      dissents and a demand for payment of the fair value of his shares if the
      action is taken. Such objection is not required from any shareholder to
      whom the corporation did not give notice of such meeting in accordance
      with this chapter or where the proposed action is authorized by written
      consent of shareholders without a meeting.
 
(b)   Within ten days after the shareholders' authorization date, which term as
      used in this section means the date on which the shareholders' vote
      authorizing such action was taken, or the date on which such consent
      without a meeting was obtained from the requisite shareholders, the
      corporation shall give written notice of such authorization or consent by
      registered mail to each shareholder who filed written objection or from
      whom written objection was not required, excepting any shareholder who
      voted for or consented in writing to the proposed action and who thereby
      is deemed to have elected not to enforce his right to receive payment for
      his shares.
 
(c)   Within twenty days after the giving of notice to him, any shareholder from
      whom written objection was not required and who elects to dissent shall
      file with the corporation a written notice of such election, stating his
      name and residence address, the number of classes of shares as to which he
      dissents and a demand for payment of the fair value of his shares. Any
      shareholder who elects to dissent from a merger under section 905 (Merger
      of subsidiary corporation) or paragraph (c) of section 907 (Merger or
      consolidation of domestic and foreign corporations) or from a share
      exchange under paragraph (g) of section 913 (Share exchanges) shall file a
      written notice of such election to dissent within twenty days after the
      giving to him of a copy of the plan of merger or exchange or an outline of
      the material features thereof under section 905 or 913.
 
(d)   A shareholder may not dissent as to less than all of the shares, as to
      which he has a right to dissent, held by him of record, that he owns
      beneficially. A nominee or fiduciary may not dissent on behalf of any
      beneficial owner as to less than all of the shares of such owner, as to
      which such nominee or fiduciary has a right to dissent, held of record by
      such nominee or fiduciary.
 
(e)   Upon consummation of the corporate action, the shareholder shall cease to
      have any of the rights of a shareholder except the right to be paid the
      fair value of his shares and any other rights under this section. A notice
      of election may be withdrawn by the shareholder at any time prior to his
      acceptance in writing of an offer made by the corporation, as provided in
      paragraph (g), but in no case later than sixty days from the date of
      consummation of the corporate action except that if the corporation fails
      to make a timely offer, as provided in paragraph (g), the time for
      withdrawing a notice of election shall be extended until sixty days from
      the date an offer is made. Upon expiration of such time, withdrawal of a
      notice of election shall require the
 
                                       D-1
<PAGE>   225
 
      written consent of the corporation. In order to be effective, withdrawal
      of a notice of election must be accompanied by the return to the
      corporation of any advance payment made to the shareholder as provided in
      paragraph (g). If a notice of election is withdrawn, or the corporate
      action is rescinded, or a court shall determine that the shareholder is
      not entitled to receive payment for his shares, or the shareholder shall
      otherwise lose his dissenter's rights, he shall not have the right to
      receive payment for his shares and he shall be reinstated to all his
      rights as a shareholder as of the consummation of the corporate action,
      including any intervening preemptive rights and the right to payment of
      any intervening dividend or other distribution or, if any such rights have
      expired or any such dividend or distribution other than in cash has been
      completed, in lieu thereof, at the election of the corporation, the fair
      value thereof in cash as determined by the board as of the time of such
      expiration or completion, but without prejudice otherwise to any corporate
      proceedings that may have been taken in the interim.
 
(f)   At the time of filing the notice of election to dissent or within one
      month thereafter the shareholder of shares represented by certificates
      shall submit the certificates representing his shares to the corporation,
      or to its transfer agent, which shall forthwith note conspicuously thereon
      that a notice of election has been filed and shall return the certificates
      to the shareholder or other person who submitted them on his behalf. Any
      shareholder of shares represented by certificates who fails to submit his
      certificates for such notation as herein specified shall, at the option of
      the corporation exercised by written notice to him within forty-five days
      from the date of filing of such notice of election to dissent, lose his
      dissenter's rights unless a court, for good cause shown, shall otherwise
      direct. Upon transfer of a certificate bearing such notation, each new
      certificate issued therefor shall bear a similar notation together with
      the name of the original dissenting holder of the shares and a transferee
      shall acquire no rights in the corporation except those which the original
      dissenting shareholder had at the time of the transfer.
 
(g)   Within fifteen days after the expiration of the period within which
      shareholders may file their notices of election to dissent, or within
      fifteen days after the proposed corporate action is consummated, whichever
      is later (but in no case later than ninety days from the shareholders'
      authorization date), the corporation or, in the case of a merger or
      consolidation, the surviving or new corporation, shall make a written
      offer by registered mail to each shareholder who has filed such notice of
      election to pay for his shares at a specified price which the corporation
      considers to be their fair value. Such offer shall be accompanied by a
      statement setting the aggregate number of shares with respect to which
      notices of election to dissent have been received and the aggregate number
      of holders of such shares. If the corporate action has been consummated,
      such offer shall also be accompanied by (1) advance payment to each such
      shareholder who has submitted the certificates representing his shares to
      the corporation, as provided in paragraph (f), of an amount equal to
      eighty percent of the amount of such offer, or (2) as to each shareholder
      who has not yet submitted his certificates a statement that advance
      payment to him of an amount equal to eighty percent of the amount of such
      offer will be made by the corporation promptly upon submission of his
      certificates. If the corporate action has not been consummated at the time
      of the making of the offer, such advance payment or statement as to
      advance payment shall be sent to each shareholder entitled thereto
      forthwith upon consummation of the corporate action. Every advance payment
      or statement as to advance payment shall include advise to the shareholder
      to the effect that acceptance
 
                                       D-2
<PAGE>   226
 
      of such payment does not constitute a waiver of any dissenters' rights. If
      the corporate action has not been consummated upon the expiration of the
      ninety day period after the shareholders' authorization date, the offer
      may be conditioned upon the consummation of such action. Such offer shall
      be made at the same price per share to all dissenting shareholders of the
      same class, or if divided into series, of the same series and shall be
      accompanied by a balance sheet of the corporation whose shares the
      dissenting shareholder holds as of the latest available date, which shall
      not be earlier than twelve months before the making of such offer, and a
      profit and loss statement or statements for not less than a twelve month
      period ended on the date of such balance sheet or, if the corporation was
      not in existence throughout such twelve month period, for the portion
      thereof during which it was in existence. Notwithstanding the foregoing,
      the corporation shall not be required to furnish a balance sheet or profit
      and loss statement or statements to any shareholder to whom such balance
      sheet or profit and loss statement or statements were previously
      furnished, nor if in connection with obtaining the shareholders'
      authorization for or consent to the proposed corporate action the
      shareholders were furnished with a proxy or information statement, which
      included financial statements, pursuant to Regulation 14A or Regulation
      14C of the United States Securities and Exchange Commission. If within
      thirty days after the making of such offer, the corporation making the
      offer and any shareholder agree upon the price to be paid for his shares,
      payment therefor shall be made within sixty days after the making of such
      offer or the consummation of the proposed corporate action, whichever is
      later, upon the surrender of the certificates for any such shares
      represented by certificates.
 
(h)   The following procedure shall apply if the corporation fails to make such
      offer within such period of fifteen days, or if it makes the offer and any
      dissenting shareholder or shareholders fail to agree with it within the
      period of thirty days thereafter upon the price to be paid for their
      shares:
 
      (1) The corporation shall, within twenty days after the expiration of
          whichever is applicable of the two periods last mentioned, institute a
          special proceeding in the supreme court in the judicial district in
          which the office of the corporation is located to determine the rights
          of dissenting shareholders and to fix the fair value of their shares.
          If, in the case of merger or consolidation, the surviving or new
          corporation is a foreign corporation without an office in this state,
          such proceeding shall be brought in the county where the office of the
          domestic corporation, whose shares are to be valued, was located.
 
      (2) If the corporation fails to institute such proceeding within such
          period of twenty days, any dissenting shareholder may institute such
          proceeding for the same purpose not later than thirty days after the
          expiration of such twenty day period. If such proceeding is not
          instituted within such thirty day period, all dissenter's rights shall
          be lost unless the supreme court, for good cause shown, shall
          otherwise direct.
 
      (3) All dissenting shareholders, excepting those who, as provided in
          paragraph (g), have agreed with the corporation upon the price to be
          paid for their shares, shall be made parties to such proceeding, which
          shall have the effect of an action quasi in rem against their shares.
          The corporation shall serve a copy of the petition in such proceeding
          upon each dissenting shareholder who is a resident of this state in
          the manner provided by law for the service of a summons, and upon each
          nonresident dissenting shareholder either by registered mail and
          publication,
 
                                       D-3
<PAGE>   227
 
          or in such other manner as is permitted by law. The jurisdiction of
          the court shall be plenary and exclusive.
 
      (4) The court shall determine whether each dissenting shareholder, as to
          whom the corporation requests the court to make such determination, is
          entitled to receive payment for his shares. If the corporation does
          not request any such determination or if the court finds that any
          dissenting shareholder is so entitled, it shall proceed to fix the
          value of the shares, which, for the purposes of this section, shall be
          the fair value as of the close of business on the day prior to the
          shareholders' authorization date. In fixing the fair value of the
          shares, the court shall consider the nature of the transaction giving
          rise to the shareholder's right to receive payment for shares and its
          effects on the corporation and its shareholders, the concepts and
          methods then customary in the relevant securities and financial
          markets for determining fair value of shares of a corporation engaging
          in a similar transaction under comparable circumstances and all other
          relevant factors. The court shall determine the fair value of the
          shares without a jury and without referral to an appraiser or referee.
          Upon application by the corporation or by any shareholder who is a
          party to the proceeding, the court may, in its discretion, permit
          pretrial disclosure, including, but not limited to, disclosure of any
          expert's reports relating to the fair value of the shares whether or
          not intended for use at the trial in the proceeding and
          notwithstanding subdivision (d) of section 3101 of the civil practice
          law and rules.
 
      (5) The final order in the proceeding shall be entered against the
          corporation in favor of each dissenting shareholder who is a party to
          the proceeding and is entitled thereto for the value of his shares so
          determined.
 
      (6) The final order shall include an allowance for interest at such rate
          as the court finds to be equitable, from the date the corporate action
          was consummated to the date of payment. In determining the rate of
          interest, the court shall consider all relevant factors, including the
          rate of interest which the corporation would have had to pay to borrow
          money during the pendency of the proceeding. If the court finds that
          the refusal of any shareholder to accept the corporate offer of
          payment for his shares was arbitrary, vexatious or otherwise not in
          good faith, no interest shall be allowed to him
 
      (7) Each party to such proceeding shall bear its own costs and expenses,
          including the fees and expenses of its counsel and of any experts
          employed by it. Notwithstanding the foregoing, the court may, in its
          discretion, apportion and assess all or any part of the costs,
          expenses and fees incurred by the corporation against any or all of
          the dissenting shareholders who are parties to the proceeding,
          including any who have withdrawn their notices of election as provided
          in paragraph (e), if the court finds that their refusal to accept the
          corporate offer was arbitrary, vexatious or otherwise not in good
          faith. The court may, in its discretion, apportion and assess all or
          any part of the costs, expenses and fees incurred by any or all of the
          dissenting shareholders who are parties to the proceeding against the
          corporation if the court finds any of the following: (A) that the fair
          value of the shares as determined materially exceeds the amount which
          the corporation offered to pay; (B) that no offer or required advance
          payment was made by the corporation; (C) that the corporation failed
          to institute the special proceeding within the period specified
          therefor; or (D) that the action of the corporation in complying with
          its obligations as
 
                                       D-4
<PAGE>   228
 
          provided in this section was arbitrary, vexatious or otherwise not in
          good faith. In making any determination as provided in clause (A), the
          court may consider the dollar amount or the percentage, or both, by
          which the fair value of the shares as determined exceeds the corporate
          offer.
 
      (8) Within sixty days after final determination of the proceeding, the
          corporation shall pay to each dissenting shareholder the amount found
          to be due him, upon surrender of the certificate for any such shares
          represented by certificates.
 
(i)   Shares acquired by the corporation upon the payment of the agreed value
      therefor or of the amount due under the final order, as provided in this
      section, shall become treasury shares or be cancelled as provided in
      section 515 (Reacquired shares), except that, in the case of a merger or
      consolidation, they may be held and disposed of as the plan of merger or
      consolidation may otherwise provide.
 
(j)   No payment shall be made to a dissenting shareholder under this section at
      a time when the corporation is insolvent or when such payment would make
      it insolvent. In such event, the dissenting shareholder shall, at his
      option:
 
      (1) Withdraw his notice of election, which shall in such event be deemed
          withdrawn with the written consent of the corporation; or
 
      (2) Retain his status as a claimant against the corporation and, if it is
          liquidated, be subordinated to the rights of creditors of the
          corporation, but have rights superior to the non-dissenting
          shareholders, and if it is not liquidated, retain his right to be paid
          for his shares, which right the corporation shall be obliged to
          satisfy when the restrictions of the paragraph do not apply.
 
      (3) The dissenting shareholder shall exercise such option under
          subparagraph (1) or (2) by written notice filed with the corporation
          within thirty days after the corporation has given him written notice
          that payment for his shares cannot be made because of the restrictions
          of this paragraph. If the dissenting shareholder fails to exercise
          such option as provided, the corporation shall exercise the option by
          written notice given to him within twenty days after the expiration of
          such period of thirty days.
 
(k)   The enforcement by a shareholder of his right to receive payment for his
      shares in the manner provided herein shall exclude the enforcement by such
      shareholder of any other right to which he might otherwise be entitled by
      virtue of share ownership, except as provided in paragraph (e), and except
      that this section shall not exclude the right of such shareholder to bring
      or maintain an appropriate action to obtain relief on the ground that such
      corporate action will be or is unlawful or fraudulent as to him.
 
(l)   Except as otherwise expressly provided in this section, any notice to be
      given by a corporation to a shareholder under this section shall be given
      in the manner provided in section 605 (Notice of meetings of
      shareholders).
 
(m)   This section shall not apply to foreign corporations except as provided in
      subparagraph (e)(2) of section 907 (Merger or consolidation of domestic
      and foreign corporations). (Last amended by Ch. 117, L. '86, eff. 9-1-86.)
