A $2,520,000 Industrial Revenue Bond, due to the City of Broomfield, Colorado,
carries an interest rate of 7.875% per annum.  The terms of the bond require
principal payments of $215,000 in 1998, $230,000 in 1999 and $2,075,000 in 2000.

A $5,350,000 Industrial Development Revenue Bond was originally issued in April
1985, through the City of Santa Ana for the construction of improvements and new
facilities at the Santa Ana plant.  It was remarketed in 1995 and carries an
average interest rate of 6.75% per annum.  The terms of the bond require
principal payments of $1,050,000 in 1998, $100,000 annually from 1999 to 2004
and $3,700,000 in 2005.  A $5,557,000 letter of credit is carried by a bank to
guarantee the repayment of this bond.  There are no compensating balance
requirements, however, the letter of credit agreement requires the Company to
make collateral payments of $350,000 on February 1, 1996, 1997 and 1998,
totaling $1,050,000 to assure the payment of principal scheduled for February 1,
1998.  The payment of $1,050,000 has been made as required.  An annual
commitment fee of 2% is charged on this letter of credit.  In addition, the
agreement contains provisions regarding net worth and working capital.  The
Company was in compliance with the aforementioned covenants at December 28,
1997.

In February 1987, the Company sold $40,250,000 of 5.875% convertible
subordinated debentures due 2012.  The debentures are convertible into common
stock at $13.55 per share.  As of September 28, 1997 

                                       8

they are redeemable at 100% of par plus accrued interest. Deferred debt issuance
costs of $1,128,000 are included in other assets and are being amortized over
the life of the debentures on a straight-line basis. In fiscal years 1987, 1988,
1989 and 1991, the Company repurchased a total of $6,969,000 of these debentures
due to favorable market conditions. In the first quarter of fiscal year 1998,
$2,000 was converted into 147 shares of common stock. Commencing in March 1997,
the debentures require annual sinking fund payments in the amount of 5% of the
principal amount thereof, less the principal amount of converted or redeemed
debentures. As of December 28, 1997, the amount of redeemed and converted
debentures would have satisfied this requirement through March 1, 1999. (See
Note 8.)

In June 1992, the Company of 10% Convertible Subordinated Notes, due in 1999, to
an officer and two existing shareholders to finance a portion of an acquisition
completed in fiscal year 1992.  The notes were converted, at $1.875 per share,
into 53,333; 613,331 and 400,000 shares of common stock in fiscal years 1996,
1997 and 1998, respectively.

In June 1997, the Company entered into a $2,700,000 equipment lease agreement
with GE Capital Public Finance, Inc., providing for monthly payments through
July 2002 of $45,000 plus interest at  5.93% per annum.

In September 1999, the Company issued notes of $2,370,000, related to the PPC
acquisition, payable to the former owners, bearing an interest rate of 7%, due
in monthly installments through September 2009.

The Company maintains a revolving credit facility with a domestic bank which
will continue through September 1999.  Under the credit facility the Company can
borrow up to $15,000,000.  The credit line has an interest rate of prime and is
secured by substantially all of the assets of the Company.  In addition, the
credit agreement contains provisions regarding net worth and working capital.
The Company is in compliance with the aforementioned covenants at December 28,
1997.  At December 28, 1997, $2,065,000 was borrowed under this credit facility.


5.    EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued SFAS No. 128,
"Earnings Per Share".  This Statement establishes standards for computing and
requires the presentation of basic and diluted earnings per share (EPS). The
Company has adopted this statement in the current period and has restated the
EPS for the prior year period as required.

Basic earnings per share have been computed based upon the weighted average
number of common shares outstanding during the respective periods.  Diluted
earnings per share have been computed, when the result is dilutive, using the
treasury stock method for stock options outstanding during the respective
periods and based upon the assumption that the convertible subordinated debt had
been converted into common stock as of the beginning of the respective periods,
with a corresponding increase in net income to reflect a reduction in related
interest expense, net of applicable taxes.

                                       9

Earnings per share for the quarters ended December 28, 1997 and December 29,
1996 were calculated as follows:

7.  CONTINGENCY

In Broomfield, Colorado, the owner of a property located adjacent to a
manufacturing facility owned by a subsidiary of the Company had filed suit
against the subsidiary and other parties, claiming that contaminants migrated to
his property, thereby diminishing its value.  In August 1995, the subsidiary
together with the former owners of the manufacturing facility, agreed to settle
the claim and to indemnify the owner of the adjacent property from remediation
costs.  Although contaminants previously used at the facility are present in
soil and groundwater on the subsidiary's property, the Company vigorously
contests any assertions that the subsidiary is the cause of the contamination;
however, there can be no assurance that recourse will be available against third
parties.  State and local agencies in Colorado are reviewing current data and
considering study and cleanup options, and it is not yet possible to predict
costs for remediation or the allocation thereof among potentially responsible
parties.

8.  SUBSEQUENT EVENTS

On December 31, 1997, the Company sold General Microcircuits, Inc., a wholly
owned subsidiary in Mooresville, North Carolina, for $5,000,000 in cash and
$2,000,000 in a note receivable.  Microsemi does not expect any material gain or
loss from this transaction.

On January 21, 1998, the Company and BKC Semiconductors Incorporated (BKC),
Lawrence, Massachusetts, jointly announced a definitive agreement whereby
Microsemi will acquire all of the common stock of BKC for approximately
$13,400,000 in cash.  Microsemi intends to finance this acquisition with cash on
hand and borrowings under its existing credit facilities.  BKC is a publicly
held 

                                       11
<PAGE>
 
company. It manufactures discrete semiconductors with sales of approximately
$11,000,000 for the fiscal year ended September 28, 1997. The acquisition will
be accounted for under the purchase method.

On January 26, 1998, the Company announced that it intends to redeem its 5.875%
convertible subordinated debentures as of February 12, 1998.  The holders may
convert their debentures into common stock of the Company, at any time prior to
5 p.m. Pacific Standard Time, February 12, 1998.  The Company expects that most
of the $33,259,000 outstanding debentures will be converted and has previously
received notices from holders of $26,826,000 in face value of debentures,
indicating their intention to convert their debentures into Common Stock.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
         AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q includes forward looking statements, the
realization of which may be impacted by certain important factors discussed
below under "Important Factors Related to Forward-Looking Statements and
associated Risks" and in Form 10-K for the fiscal year ended September 28, 1997.


Introduction
- ------------

Microsemi Corporation is a multinational supplier of high reliability power
semiconductors, surface mount and custom diode assemblies for the electronics,
computer, telecommunications, defense/aerospace and medical markets.  The
Company's semiconductor products include diodes, transistors and silicon
controlled rectifiers (SCR's) which can be used in virtually all electrical and
electronic circuits.  Typical functions include solid state switching, signal
processing, voltage and power regulation, circuit protection and absorption of
electrical surges and transient voltage spikes. Technologies for these devices
range from the very mature mesa rectifier diodes, still used in all types of
power supply applications, to the newly designed micro-miniature transient
absorbers, which are mounted within the cables used to connect computer or
telecommunications equipment.


Capital Resources and Liquidity
- -------------------------------

Microsemi Corporation's operations in the three months ended December 28, 1997
were funded with internally generated funds and borrowings under the Company's
line of credit. In September 1997, the Company renewed its credit line with a
bank. Under the current line of credit, the Company can borrow up to
$15,000,000. As of December 28, 1997, $2,065,000 was borrowed under this credit
facility. At December 28, 1997, the Company had $5,753,000 in cash and cash
equivalents.

A $5,350,000 Industrial Development Revenue Bond was originally issued in April
1985, through the City of Santa Ana Industrial Development Authority for the
construction of improvements and new facilities at the Santa Ana plant. It was
remarketed in 1995 and carries an average interest rate of 6.75% per annum. The
terms of the bond require principal payments of $1,050,000 in 1998, $100,000
annually from 1999 to 2004 and $3,700,000 in 2005. A $5,557,000 letter of credit
is carried by a bank to guarantee the repayment of this bond. The principal
payment of $1,050,000, consisting of $350,000 in cash and $700,000 in matured
certificates of deposit, scheduled for February 1, 1998 has been made as
required.

Based upon information currently available, the Company believes that it can
meet its current operating cash and debt service requirements with internally
generated funds together with its available borrowings.

In October 1996, Microsemi purchased certain assets and the right to manufacture
a selected group of products of the high-reliability portion of SGS Thomson's
Radio Frequency (RF) Semiconductor business in Montgomeryville, Pennsylvania
(the RF Products acquisition). In September 1997, Microsemi PPC, Inc. (PPC),
formerly known as Micro PPC Acquisition Corp., a wholly owned subsidiary of the
Company, purchased substantially all of the assets and assumed certain
liabilities of PPC Products Corp., Technett Seals Inc., and Semiconductors, Inc.
(collectively referred to as PPC Products). PPC Products is a supplier of power
transistors, fixed and adjustable linear regulators, and 

                                       13
<PAGE>
 
power rectifiers and is located in Riviera Beach, Florida. The aggregate
purchase price for both entities included approximately $5,201,000 in cash and
$3,070,000 in notes payable.

The Company's 5.875% Convertible Subordinated Debentures due 2012 require
semiannual interest payments of approximately $977,000. The Debentures are
callable at 100% of face value and are convertible at the option of the holder
into Common Stock at a conversion price of $13.55 per share. On January 26,
1998, the Company announced that it intends to redeem the debentures. (See note
8.)

On December 31, 1997, the Company sold General Microcircuits, Inc., a wholly
owned subsidiary in Mooresville, North Carolina, for $5,000,000 in cash and
$2,000,000 in a promissory note. Microsemi does not expect any material gain or
loss from this transaction.

On January 21, 1998, the Company and BKC Semiconductors Incorporated (BKC),
Lawrence, Massachusetts, jointly announced a definitive agreement whereby
Microsemi will acquire all of the outstanding stock of BKC for approximately
$13,400,000. (See Note 8.)

On January 29, 1998, the Company announced that it has made an equity investment
of approximately $1,000,000 in Xemod, Inc. Xemod was founded in 1994 and
headquartered in Sunnyvale, California. It designs, manufacturers and markets
power amplifier semiconductor components targeted at the cellular and wireless
communication markets.

The Company has no other significant capital commitments.

The average collection period of accounts receivable was 52 days for the current
quarter compared to 59 days for the same period of fiscal year 1997. The
improvement was due to higher sales and a better collection effort.

The average days sales of products in inventories was 152 for the three months
ended December 28, 1997 compared to 171 days for the corresponding period of
fiscal year 1997. The decrease was primarily due to higher shipments in the
current period and an effort to control inventories.

RESULTS OF OPERATIONS FOR THE QUARTER ENDED DECEMBER 28, 1997 COMPARED TO THE
QUARTER ENDED DECEMBER 29, 1996.

Net sales for the first quarter of fiscal year 1998 increased $8,293,000 to
$44,052,000, from $35,759,000 for the first quarter of fiscal year 1997; this
increase was primarily due to strong demand for the space market related
products, higher shipments of the Powermite and the addition of PPC Products,
which was acquired in September 1997.

Gross profit increased $2,275,000 to $12,019,000 or 27.3% of sales for the
current quarter of fiscal year 1998 from $9,744,000 or 27.2% of sales for the
first quarter of fiscal year 1997. The increase of gross profit was due to
higher sales.

Operating expenses for the current quarter of fiscal year 1998 increased
$647,000 compared to that of the corresponding period of the prior year;
primarily due to the addition of the PPC subsidiary.

The effective tax rates of 38% and 42% in the first quarters of fiscal years
1998 and 1997 were the combined result of taxes computed on foreign and domestic
income. The prior year tax rate was higher due to certain non-deductible losses,
a less favorable mix of worldwide income and other adjustments.

Important factors related to forward-looking statements and associated risks
- ----------------------------------------------------------------------------

This Form 10-Q contains certain forward-looking statements that are based on
current expectations and involve a number of risks and uncertainties.  The
forward-looking statements included herein are based on, among other items,
current assumptions that the Company will be able to meet its current operating
cash and debt service requirements with internally generated funds and its
available line of credit, that it will be able to successfully resolve disputes
and other business matters as anticipated, that competitive conditions within
the semiconductor, surface mount and custom diode assembly industries will not
change materially or adversely, that the Company will retain existing key
personnel, that the Company's forecasts will reasonably anticipate market demand
for its products, and that there will be no materially adverse change in the
Company's operations or business.  Other factors that could cause results to
vary materially from current expectations are discussed elsewhere in this Form
10-Q. Assumptions relating to the foregoing involve judgments that are difficult
to predict accurately and are subject to many factors that can materially affect
results.  Forecasting and other management decisions are subjective in many
respects and thus susceptible to interpretations and periodic revisions based on
actual experience and business developments, the impact of which may cause the
Company to alter its forecasts, which may in turn affect the Company's results.
In light of the factors that can materially affect the forward-looking
information included herein, the inclusion of such information should not be
regarded as a representation by the Company or any other person that the
objectives or plans of the Company will be achieved.

The unaudited consolidated financial statements and notes should be read in
conjunction with the financial statements and notes thereto in the Annual Report
in Form 10-K for the fiscal year ended September 28, 1997.  Additional factors
that could cause results to vary materially from current expectations are
discussed under the heading "Important factors related to forward-looking
statements and associated risks" in the Company's annual report in Form 10-K as
filed December 29, 1997 with the Securities and Exchange Commission, and
elsewhere in that Form 10-K.


Order Backlog
- -------------

   The Company's consolidated order backlog was $67,000,000 as of December 28,
1997, compared to $64,000,000 at December 29, 1996 and $67,000,000 at September
28, 1997. Backlog of General Microcircuits, Inc., has been eliminated from the
previously published amounts. (See note 8.)

The Company's backlog as of any particular date may not be representative of
actual sales for any succeeding period because lead times for the release of
purchase orders depend upon the scheduling practices of individual customers,
the delivery times of new or non-standard products can be affected by scheduling
factors and other manufacturing considerations, the rate of booking new orders
can vary significantly from month to month, and the possibility of customer
changes in delivery schedules or cancellations of orders.

                                   AGREEMENT
                                        
     THIS AGREEMENT dated as of November 18, 1997 is made by and between Philip
Frey, Jr. ("Executive") and MICROSEMI CORPORATION, a Delaware corporation
("Company")

     NOW, THEREFORE, for good and valuable considerations, receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

     1.   Term.  The term of this Agreement shall commence on the date hereof.
The term of this Agreement shall be renewed automatically on a daily basis so
that the outstanding term is always two (2) years after the date on which notice
of non-renewal or termination of this Agreement is given by the Executive to the
Company or by the Company to the Executive. This Agreement relates to
Executive's employment with the Company, or any subsidiary, successor, assign or
affiliate of the Company, under any written or oral agreement. For purposes of
the following provisions "Date of Termination" means the effective date of
termination of Executive's employment with any of the entities described above,
after notice and lapse of the notice period as required herein.

     2.   Terminations by Executive.

Control, Executive may terminate his active employment under his oral or written
employment agreement with the Company upon five (5) days' written notice to the
Company given within ninety (90) days following the date on which the Executive
becomes aware of any of the following events, each of which shall be deemed to
be good reason for termination by Executive:

              (i)   any reduction in, or limitation upon, the compensation,
reimbursable expenses or other benefits provided in this Agreement, other than
(A) as generally effected by valid public law or regulation or (B) as results
from change in the amount of the incentive compensation pool if not resulting
from changes in the incentive pool formula or allocations and not resulting from
accounting or operational effects of the acquisition;

              (ii)  any change in assignment of Executive's primary duties to a
work location more than 50 miles from the Company's principal executive office
at 2830 South Fairview Street, Santa Ana, California 92704, without Executive's
prior written consent;

              (iii) any failure by the Company to obtain the assumption of this
Agreement by any successor or assign of the Company;

                                                                               3
<PAGE>
 
              (iv)  any material breach by the Company of any provision of this
Agreement; or

              (v)   any action taken by the Board or a standing Committee of the
Board in connection with, or the formation of a special Committee of the Board
for the purpose of, effecting any of the events listed in subparagraphs (i)
through (iv) immediately above;

          b.  Change of Control.  For purposes of this Agreement, "Change in
Control" means the occurrence of any of the following events:

              (i)   Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing more than fifty percent
(50%) of the total voting power represented by the Company's then outstanding
voting securities;

              (ii)  Consummation of a merger or consolidation of the Company
with any other corporation, other than a merger or consolidation which would
result in the voting securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least fifty-one
percent (51%) of the total voting power represented by the voting securities of
the Company or such surviving entity outstanding immediately after such merger
or consolidation, or the stockholders of the Company approving a plan of
complete liquidation of the Company or a consummation of the sale or disposition
by the Company of all or substantially all of the Company's assets.

          c.  Voluntary Termination by Executive.  After a Change in Control,
without reason or for any reason other than one set forth in Section 2.a above,
Executive may voluntarily terminate his employment with the Company under any
oral or written employment agreement upon a minimum of one (1) month's written
notice to the Company.

     3.   Executive's Benefits Following Termination.

          a.  Executive's Benefits in Termination by Executive without "Good
Reason" following Change in Control. If this Agreement is terminated following a
Change in Control by Executive without "Good Reason":

                                                                               4

to Executive under all plans and all stock options and general stock
appreciation rights granted by the Company to Executive will remain in

Hire Date to the date the Company gives notice of termination), subject to
termination under Section 7.

              (vi)   Retirement Plans; Unvested Company Contribution.  The
Executive shall be entitled to receive, not later than the fifteenth (15th) day

ownership plan, or any plan established as a supplement to any of the

<PAGE>
 
shall not be required to pay Executive any amount of unvested Company
contributions credited to the Executive's account under any tax-qualified
employee benefit plan maintained by the Company as of the Date of Termination.
In the event that this paragraph should conflict with the provisions of any of
the Company's tax-qualified employee benefit plans and any other plan, program
or arrangement relating to deferred compensation, retirement or other benefits
including, without limitation, any profit sharing, 401(k), employee stock
ownership plan, or any plan established as a supplement to any of the
aforementioned plans, then the provisions of the plan shall govern.

              (vii)  Vacation and Sick Leave.  The Company shall also pay

pro rata amount of his base salary under his employment agreement, in effect on

<PAGE>
 
ending n months after the Date of Termination (where n is equal to the sum of
three (3) months plus a number of months equal to the number of years elapsed
from the Hire Date to the date the Date of Termination), in either case subject
to termination as described in Section 7.

              (iv)   Stock Options.  The restriction or forfeiture period on any

or other benefits including, without limitation, any profit sharing, 401(k),
employee stock ownership plan, or any plan established as a supplement to any of

                                                                               7
<PAGE>
 
aforementioned plans, then the provisions of the plan shall govern, provided
that the Company's contribution shall vest pursuant to this Section.

              (vii)  Vacation and Sick Leave.  The Company shall also pay
Executive, not later than the second day following the Date of Termination, a
pro rata amount of his base salary under his employment agreement, in effect on
the Date of Termination, for each day of vacation leave which has accrued as of
the Date of Termination, but which is unpaid as of such date, to which Executive
is entitled under the Company's vacation leave policy. The Company shall be
required to pay for sick leave days only to the extent that Executive has taken
sick leave on or prior to the Date of Termination to which Executive is entitled
under the Company's sick leave policy.

              (viii) General.  Executive or his estate shall also be entitled to
any other amounts then owing or accrued but unpaid to the Executive pursuant to
any plans or arrangements of the Company.

     4.   Other Benefits Following Termination.  Executive shall also be
entitled to the following additional benefits upon or following such
termination:

          a.  During the period following employment or benefits hereunder, to
the extent required by law, Executive shall have the rights under the
Consolidated Omnibus Budget Reconciliation Act ("COBRA"), or any successor
statute.

     5.   Excise Taxes.  If all or any portion of the amounts payable to
Executive or on Executive's behalf under this Agreement or otherwise are subject
to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986,
as amended (or similar state tax and/or assessment), the Company shall pay to
Executive an amount necessary to place Executive in the same after-tax position
as Executive would have been had no such excise tax been imposed. The amount
payable pursuant to the preceding sentence shall be grossed-up to the extent
necessary to pay income and excise taxes due on such amount. The determination
of the amount of any such tax indemnity shall initially be made by the
independent accounting firm then employed by the Company. If at a later date it
is determined (pursuant to final regulations or published rulings of the IRS,
final judgment of a court of competent jurisdiction or otherwise) that the
amount of excise taxes payable by Executive is greater than the amount initially
so determined, then the Company (or its successor) shall pay Executive an amount
equal to the sum of (1) such additional excise taxes, (2) any interest, fines
and penalties resulting from such underpayment, plus (3) a gross-up amount

                                                                               8
<PAGE>
 
necessary to reimburse Executive for any income, excise or other taxes payable
by Executive with respect to the amounts specified in (1) and (2) above, and the
reimbursement provided by this clause (3).

     6.   Indemnification. For at least ten (10) years following the Date of
Termination for any reason, Executive shall continue to be indemnified under the
Company's Certificate of Incorporation and Bylaws at least to the same extent
indemnification was available prior to the Date of Termination and permitted by
law, and Executive shall be insured under the directors' and officers' liability
insurance, the fiduciary liability insurance and the professional liability
insurance policies that are the same as, or provide coverage at least equivalent
to, those applicable or made available by the Company to the then members of
senior management of the Company. Independent of such provision, if at any time
Executive is made, or threatened to be made, a party to any legal action or
proceeding, whether civil or criminal, by reason of the fact that Executive is
or was a director or officer of the Company or serves or served any other
corporation fifty percent (50%) or more owned or controlled by the Company in
any capacity at the Company's request, Executive shall be indemnified by the
Company, and the Company shall pay Executive's related expenses when and as
incurred, all to the full extent permitted by law.

     7.   Obligatory Restrictions on Executive.  Executive agrees that during
the period of the commencing on the Date of Termination and extending the lesser
of two years or n months (where n is equal to the sum of three (3) months plus a
number of months equal to the number of years elapsed from the Hire Date to the
date notice of termination is given), except as provided below or with the
Company's written consent, he will be bound by the following restrictive
covenants:

          a.  Non-Competition.  Following any involuntary termination following
a Change in Control or a termination by Executive for Good Reason following a
Change in Control, the restrictions in this paragraph, and any similar
restrictions under any employment agreement between the Company and Executive or
otherwise shall be of no force or effect. In the event of a voluntary
termination (other than for Good Reason) by Executive following a Change in
Control, Executive will not, directly or indirectly, engage for his own account
in, or own, manage, operate, control, be employed as an employee or consultant,
buy, participate in, or be connected in any manner with the ownership,
management, operation or control of any firm, corporation, association, or other
business entity which is in competition with the business of the Company;
provided that Executive may invest in a business competitive with the Company to
an extent not exceeding five percent (5%) of the total outstanding shares at the
time of such investment in each one or more

                                                                               9
<PAGE>
 
companies. A business will be considered for this purpose in competition with
the Company if and only if the products of such business include more than one-
third of the Company's products as of immediately prior to the Change in
Control. In the event of a breach or threatened breach by Executive of the
provisions of this paragraph, the Company shall be entitled to an injunction
restraining Executive from violating the provisions of this paragraph.

          b.  No Solicitation of Employees.  Executive will not solicit or, with
the exception of any persons related to Executive by blood, marriage, or
adoption, not more remote than first cousin, employ any current or future
employee of the Company and will not intentionally disparage the Company, its
management or its products.

          c.  Consideration.  Executive's obligations are made partly in
consideration of the salary and other benefits paid or committed to be paid by
the Company following the Date of Termination. The restrictive covenants on the
part of Executive set forth in this Section 20 shall survive the termination of
this Agreement, and the existence of any claims or cause of action by Executive
against the Company, whether predicated on this Agreement or otherwise, shall
not constitute a defense in the enforcement of these covenants.

     8.   Termination of Certain Benefits Following New Employment.  If
Executive accepts a substantial engagement or employment ("New Employment") with
any other corporation, partnership, trust, government or other entity at any
time during the term of benefit continuation referred to above, the Company may
elect that Executive cease to be entitled to car allowance or medical, dental or
vision insurance benefits effective upon the commencement of such other
engagement or employment. However, Executive shall nevertheless continue to be
entitled to the other benefits of this Agreement and shall continue to be bound
by the provisions of this Agreement for any remaining duration of any period
then applicable to Executive. For the purposes of this provision, "employment"
or "engagement" shall exclude (i) service as an officer or director of a
personal investment holding company, (ii) service as a director on the Board of
a corporation or nonprofit organization, (iii) engagement as a bona fide part-
time consultant, or (iv) self-employment or engagement as an officer or director
of an operating corporation or enterprise (as opposed to a personal investment
holding company) founded or controlled by Executive and which has (and only so
long as it continues to have) revenues of less than $25 million per year.

                                                                              10
<PAGE>
 
     9.   No Mitigation by Executive Required.  Company recognizes that because
of Executive's special talents, stature and opportunities in the electronics
industry, in the event of termination by the Company or Executive before the end
of the agreed term, the parties acknowledge and agree that the provisions of
this Agreement regarding further payment of base salary, bonuses, and the
exercisability of stock options and lapse of the restrictive or forfeiture
period on restricted stock constitute fair and reasonable provisions for the
consequences of such termination, do not constitute a penalty, and such payments
and benefits shall not be limited or reduced by amounts Executive might earn or
be able to earn from any other employment or ventures during the remainder of
the agreed term of this Agreement. Executive shall not be required to mitigate
the amount of any payment provided for in this Agreement by seeking other
employment or otherwise.

     10.  Binding Agreement.  This Agreement shall be binding upon and inure to
the benefit of Executive, his heirs, distributees and assigns, and the Company,
its successors and assigns. Executive may not, without the express written
permission of the Company, assign or pledge any rights or obligations hereunder
to any person, firm or corporation. Such permission shall not be unreasonably
withheld. If the Executive should die while any amount would still be payable to
Executive if he had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with this Agreement to the
Executive's estate.

     11.  No Attachment.  Except as required by law, no right to receive
payments under this Agreement shall be subject to anticipation, commutation,
alienation, sale, assignment, encumbrance, charge, pledge or hypothecation or to
execution, attachment, levy or similar process or assignment by operation of
law, and any attempt, voluntary or involuntary, to effect any such action shall
be null, void and of no effect.

     12.  Assignment and Other Rights.  The Company will require any successor
(whether direct or indirect, by operation of law, by purchase, merger,
consolidation or otherwise to all or substantially all of the business and/or
assets of the Company) to expressly assume and agree to perform this Agreement
in the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place. Failure of the Company to
obtain such assumption and agreement prior to the effectiveness of any such
succession shall be a breach of this Agreement and shall entitle Executive to
compensation from the Company in the same

                                                                              11
<PAGE>
 
amount and on the same terms as the Executive would be entitled hereunder,
except that for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be the Date of Termination. As used in
this Agreement, "Company" shall mean the Company as defined above and any
successor to its business and/or assets that assumes and agrees to perform this
Agreement by operation of law, or otherwise.

     13.  Waiver.  No term or condition of this Agreement shall be deemed to
have been waived, nor shall there be any estoppel against the enforcement of any
provision of this Agreement, except by written instrument of the party charged
with such waiver or estoppel. No such written waiver shall be deemed a
continuing waiver unless specifically stated therein, and each such waiver shall
operate only as to the specific term or condition waived and shall not
constitute a waiver of such term or condition for the future or as to any act
other than that specifically waived.

     14.  Notice.  For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed to the
Executive at his home address appearing in the records of the Company, in the
case of the Executive, and in the case of the Company, to the attention of the
Chairman of the Board at the principal executive offices of the Company, or to
such other address as either party may have furnished to the other in writing in
accordance herewith, except that notice of change of address shall be effective

finally by arbitration.

          b.  The arbitration shall be conducted in accordance with the

          c.  The Company shall pay all of the fees, if any, and expenses of

the dispute may designate by mutual written consent.

          e.  Any decision or award of the tribunal shall be final and binding
upon the parties to the arbitration proceeding.  The parties hereto hereby waive
to the extent permitted by law any rights to appeal or to review such award by
any court or tribunal.  The parties hereto agree that the award may be enforced
against the parties to the arbitration proceeding or their assets wherever the
award may be entered in any court having jurisdiction thereof.

          f.  The parties stipulate that discovery may be held in any such

full compensation in effect when the notice giving rise to the dispute was given
(including, but not limited to, base salary) and continue the Executive as a
participant in all compensation, employee benefit and insurance plans, programs,
arrangements and perquisites in which the Executive was participating or
entitled when the notice giving rise to the dispute was given, until the dispute
is finally resolved in accordance with this paragraph (c).  Amounts paid under
this paragraph (c) shall be repaid to the Company or be offset against or reduce
any other amounts due the Executive under this Agreement, as appropriate, only
upon the final resolution of the dispute.

     19.  Entire Agreement.  As of the date hereof, all previous agreements
relating to the employment of Executive, however styled, are hereby superseded
to the extent inconsistent herewith, and, excepting Executive's present
participation in Company stock and/or other benefit plans or programs and the
agreements thereunder, which are hereby reaffirmed in all respects by both
parties thereto except as expressly modified by this Agreement, this Agreement
embodies all agreements, contracts, and understandings by and between the
parties hereto. In addition, this Agreement supersedes and amends any subsequent
employment agreement between Executive and the Company except to the extent such
subsequent agreement expressly provides or provides benefits in excess of those
herein provided. Should any other agreement, plan or arrangement between Company
and Executive or other officers or employees of the Company provide for greater
benefits upon a change in control, the terms of such other agreement, plan or
arrangement shall apply to Executive on a "most favored" basis. This Agreement
may not be changed orally, but only by an agreement in writing signed by the
party against whom enforcement of any waiver, change, modification, extension,
or discharge is sought.

     20.  Separate Counsel.  The Company has been represented by Stradling,
Yocca, Carlson & Rauth in the negotiation and execution of this Agreement. The
Executive has been invited and given opportunity to engage counsel to review or
negotiate this Agreement, and Executive has either done so or chosen not to

     NOW, THEREFORE, for good and valuable considerations, receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

     1.  Term.  The term of this Agreement shall commence on the date hereof.
The term of this Agreement shall be renewed automatically on a daily basis so
that the outstanding term is always two (2) years after the date on which notice
of non-renewal or termination of this Agreement is given by the Executive to the

reimbursable expenses or other benefits provided in this Agreement, other than

accounting or operational effects of the acquisition;

              (ii)   any change in assignment of Executive's primary duties to a
work location more than 50 miles from the Company's principal executive office
at 2830 South Fairview Street, Santa Ana, California 92704, without Executive's

              (iii)  any failure by the Company to obtain the assumption of

                                                                               3
<PAGE>
 
               (iv) any material breach by the Company of any provision of this
Agreement; or

14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing more than fifty percent
(50%) of the total voting power represented by the Company's then outstanding
voting securities;

               (ii) Consummation of a merger or consolidation of the Company
with any other corporation, other than a merger or consolidation which would
result in the voting securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least fifty-one
percent (51%) of the total voting power represented by the voting securities of
the Company or such surviving entity outstanding immediately after such merger
or consolidation, or the stockholders of the Company approving a plan of
complete liquidation of the Company or a consummation of the sale or disposition
by the Company of all or substantially all of the Company's assets.

          c.   Voluntary Termination by Executive.  After a Change in Control,
without reason or for any reason other than one set forth in Section 2.a above,

including, without limitation, any profit sharing, 401(k), employee stock

Executive or on Executive's behalf under this Agreement or otherwise are subject
to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986,

Executive an amount necessary to place Executive in the same after-tax position
as Executive would have been had no such excise tax been imposed. The amount
payable pursuant to the preceding sentence shall be grossed-up to the extent
necessary to pay income and excise taxes due on such amount. The determination

is determined (pursuant to final regulations or published rulings of the IRS,
final judgment of a court of competent jurisdiction or otherwise) that the
amount of excise taxes payable by Executive is greater than the amount initially
so determined, then the Company (or its successor) shall pay Executive an amount
equal to the sum of (1) such additional excise taxes, (2) any interest, fines
and penalties resulting from such underpayment, plus (3) a gross-up amount

                                                                               8

necessary to reimburse Executive for any income, excise or other taxes payable
by Executive with respect to the amounts specified in (1) and (2) above, and the
reimbursement provided by this clause (3).

     6.  Indemnification.  For at least ten (10) years following the Date of
Termination for any reason, Executive shall continue to be indemnified under the
Company's Certificate of Incorporation and Bylaws at least to the same extent
indemnification was available prior to the Date of Termination and permitted by
law, and Executive shall be insured under the directors' and officers' liability
insurance, the fiduciary liability insurance and the professional liability
insurance policies that are the same as, or provide coverage at least equivalent
to, those applicable or made available by the Company to the then members of
senior management of the Company. Independent of such provision, if at any time
Executive is made, or threatened to be made, a party to any legal action or
proceeding, whether civil or criminal, by reason of the fact that Executive is
or was a director or officer of the Company or serves or served any other
corporation fifty percent (50%) or more owned or controlled by the Company in
any capacity at the Company's request, Executive shall be indemnified by the
Company, and the Company shall pay Executive's related expenses when and as
incurred, all to the full extent permitted by law.

     7.  Obligatory Restrictions on Executive.  Executive agrees that during the
period of the commencing on the Date of Termination and extending the lesser of
two years or n months (where n is equal to the sum of three (3) months plus a
number of months equal to the number of years elapsed from the Hire Date to the
date notice of termination is given), except as provided below or with the
Company's written consent, he will be bound by the following restrictive
covenants:

         a.  Non-Competition. Following any involuntary termination following a
Change in Control or a termination by Executive for Good Reason following a
Change in Control, the restrictions in this paragraph, and any similar
restrictions under any employment agreement between the Company and Executive or
otherwise shall be of no force or effect. In the event of a voluntary
termination (other than for Good Reason) by Executive following a Change in
Control, Executive will not, directly or indirectly, engage for his own account
in, or own, manage, operate, control, be employed as an employee or consultant,
buy, participate in, or be connected in any manner with the ownership,
management, operation or control of any firm, corporation, association, or other
business entity which is in competition with the business of the Company;
provided that Executive may invest in a business competitive with the Company to
an extent not exceeding five percent (5%) of the total outstanding shares at the
time of such investment in each one or more

                                                                               9
<PAGE>
 
companies. A business will be considered for this purpose in competition with
the Company if and only if the products of such business include more than one-
third of the Company's products as of immediately prior to the Change in
Control. In the event of a breach or threatened breach by Executive of the
provisions of this paragraph, the Company shall be entitled to an injunction
restraining Executive from violating the provisions of this paragraph.

          b.  No Solicitation of Employees. Executive will not solicit or, with
the exception of any persons related to Executive by blood, marriage, or
adoption, not more remote than first cousin, employ any current or future
employee of the Company and will not intentionally disparage the Company, its
management or its products.

          c.  Consideration. Executive's obligations are made partly in
consideration of the salary and other benefits paid or committed to be paid by
the Company following the Date of Termination. The restrictive covenants on the
part of Executive set forth in this Section 20 shall survive the termination of
this Agreement, and the existence of any claims or cause of action by Executive
against the Company, whether predicated on this Agreement or otherwise, shall
not constitute a defense in the enforcement of these covenants.

     8.   Termination of Certain Benefits Following New Employment. If Executive
accepts a substantial engagement or employment ("New Employment") with any other
corporation, partnership, trust, government or other entity at any time during
the term of benefit continuation referred to above, the Company may elect that
Executive cease to be entitled to car allowance or medical, dental or vision
insurance benefits effective upon the commencement of such other engagement or
employment. However, Executive shall nevertheless continue to be entitled to the
other benefits of this Agreement and shall continue to be bound by the
provisions of this Agreement for any remaining duration of any period then
applicable to Executive. For the purposes of this provision, "employment" or
"engagement" shall exclude (i) service as an officer or director of a personal
investment holding company, (ii) service as a director on the Board of a
corporation or nonprofit organization, (iii) engagement as a bona fide part-time
consultant, or (iv) self-employment or engagement as an officer or director of
an operating corporation or enterprise (as opposed to a personal investment
holding company) founded or controlled by Executive and which has (and only so
long as it continues to have) revenues of less than $25 million per year.

                                                                              10
<PAGE>
 
     9.   No Mitigation by Executive Required.  Company recognizes that because
of Executive's special talents, stature and opportunities in the electronics
industry, in the event of termination by the Company or Executive before the end
of the agreed term, the parties acknowledge and agree that the provisions of
this Agreement regarding further payment of base salary, bonuses, and the
exercisability of stock options and lapse of the restrictive or forfeiture
period on restricted stock constitute fair and reasonable provisions for the
consequences of such termination, do not constitute a penalty, and such payments
and benefits shall not be limited or reduced by amounts Executive might earn or
be able to earn from any other employment or ventures during the remainder of
the agreed term of this Agreement. Executive shall not be required to mitigate
the amount of any payment provided for in this Agreement by seeking other
employment or otherwise.

     10.  Binding Agreement. This Agreement shall be binding upon and inure to
the benefit of Executive, his heirs, distributees and assigns, and the Company,
its successors and assigns. Executive may not, without the express written
permission of the Company, assign or pledge any rights or obligations hereunder
to any person, firm or corporation. Such permission shall not be unreasonably
withheld. If the Executive should die while any amount would still be payable to
Executive if he had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with this Agreement to the
Executive's estate.

     11.  No Attachment. Except as required by law, no right to receive payments
under this Agreement shall be subject to anticipation, commutation, alienation,
sale, assignment, encumbrance, charge, pledge or hypothecation or to execution,
attachment, levy or similar process or assignment by operation of law, and any
attempt, voluntary or involuntary, to effect any such action shall be null, void
and of no effect.

     12.  Assignment and Other Rights. The Company will require any successor
(whether direct or indirect, by operation of law, by purchase, merger,
consolidation or otherwise to all or substantially all of the business and/or
assets of the Company) to expressly assume and agree to perform this Agreement
in the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place. Failure of the Company to
obtain such assumption and agreement prior to the effectiveness of any such
succession shall be a breach of this Agreement and shall entitle Executive to
compensation from the Company in the same

                                                                              11
<PAGE>
 
amount and on the same terms as the Executive would be entitled hereunder,
except that for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be the Date of Termination. As used in
this Agreement, "Company" shall mean the Company as defined above and any
successor to its business and/or assets that assumes and agrees to perform this
Agreement by operation of law, or otherwise.

     13.  Waiver.  No term or condition of this Agreement shall be deemed to
have been waived, nor shall there be any estoppel against the enforcement of any
provision of this Agreement, except by written instrument of the party charged
with such waiver or estoppel. No such written waiver shall be deemed a
continuing waiver unless specifically stated therein, and each such waiver shall
operate only as to the specific term or condition waived and shall not
constitute a waiver of such term or condition for the future or as to any act
other than that specifically waived.

     14.  Notice.  For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed to the
Executive at his home address appearing in the records of the Company, in the
case of the Executive, and in the case of the Company, to the attention of the
Chairman of the Board at the principal executive offices of the Company, or to
such other address as either party may have furnished to the other in writing in
accordance herewith, except that notice of change of address shall be effective
only upon receipt. Acceptance by Executive of benefits of participation shall
constitute a certification by Executive of his continued eligibility for
participation.

     15.  Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of California.

     16.  Costs.  Each of the parties shall pay its own expenses, including
attorneys' fees, in the negotiation and preparation of this Agreement.

     17.  Severability.  If, for any reason, any provision of this Agreement is
held invalid, such invalidity shall not affect any other provision of this
Agreement not held so invalid, and each such other provision shall to the full
extent consistent with law continue in full force and effect. If

                                                                              12
<PAGE>
 
any provision of this Agreement shall be held invalid in part, such invalidity
shall in no way affect the rest of such provision not held so invalid, and the
rest of such provision, together with all other provisions of this Agreement,
shall to the full extent consistent with law continue in full force and effect.
If this Agreement is held invalid or cannot be enforced, then to the full extent
permitted by law, any prior agreement between the Company (or any predecessor
thereof) and Executive shall be deemed reinstated as if this Agreement has not
been executed.

     18.  Arbitration.

          a.  Any disagreement, dispute, controversy or claim arising out of or
in any way related to this Agreement or the subject matter thereof or the
interpretation hereof or any arrangements relating hereto or contemplated herein
or the breach, termination or invalidity hereof shall be settled exclusively and
finally by arbitration.

          b.  The arbitration shall be conducted in accordance with the
Commercial Arbitration Rules (the "Arbitration Rules") of the American
Arbitration Association (the "AAA").  The arbitral tribunal shall consist of one
arbitrator.

          c.  The Company shall pay all of the fees, if any, and expenses of
such arbitration, and shall also pay all Executive's expenses, including
attorneys' fees, incurred in connection with the arbitration regardless of the
final outcome of such arbitration.

          d.  The arbitration shall be conducted in Orange County, California,
or in any other city or county in the United States of America as the parties to
the dispute may designate by mutual written consent.

          e.  Any decision or award of the tribunal shall be final and binding
upon the parties to the arbitration proceeding.  The parties hereto hereby waive
to the extent permitted by law any rights to appeal or to review such award by
any court or tribunal.  The parties hereto agree that the award may be enforced
against the parties to the arbitration proceeding or their assets wherever the
award may be entered in any court having jurisdiction thereof.

          f.  The parties stipulate that discovery may be held in any such
arbitration proceeding as provided in Section 1283.05 of the California Code of
Civil Procedure, as may be amended or revised from time to time.

                                                                              13
<PAGE>
 
          g.  During the period until the dispute is finally resolved in
accordance with this Section, the Company will continue to pay the Executive his
full compensation in effect when the notice giving rise to the dispute was given
(including, but not limited to, base salary) and continue the Executive as a
participant in all compensation, employee benefit and insurance plans, programs,
arrangements and perquisites in which the Executive was participating or
entitled when the notice giving rise to the dispute was given, until the dispute
is finally resolved in accordance with this paragraph (c).  Amounts paid under
this paragraph (c) shall be repaid to the Company or be offset against or reduce
any other amounts due the Executive under this Agreement, as appropriate, only
upon the final resolution of the dispute.

     19.  Entire Agreement.  As of the date hereof, all previous agreements
relating to the employment of Executive, however styled, are hereby superseded
to the extent inconsistent herewith, and, excepting Executive's present
participation in Company stock and/or other benefit plans or programs and the
agreements thereunder, which are hereby reaffirmed in all respects by both
parties thereto except as expressly modified by this Agreement, this Agreement
embodies all agreements, contracts, and understandings by and between the
parties hereto. In addition, this Agreement supersedes and amends any subsequent
employment agreement between Executive and the Company except to the extent such
subsequent agreement expressly provides or provides benefits in excess of those
herein provided. Should any other agreement, plan or arrangement between Company
and Executive or other officers or employees of the Company provide for greater
benefits upon a change in control, the terms of such other agreement, plan or
arrangement shall apply to Executive on a "most favored" basis. This Agreement
may not be changed orally, but only by an agreement in writing signed by the
party against whom enforcement of any waiver, change, modification, extension,
or discharge is sought.

     20.  Separate Counsel.  The Company has been represented by Stradling,
Yocca, Carlson & Rauth in the negotiation and execution of this Agreement. The
Executive has been invited and given opportunity to engage counsel to review or
negotiate this Agreement, and Executive has either done so or chosen not to
engage counsel.

                                                                              14

     IN WITNESS WHEREOF, the parties have executed this Employment Agreement as
of the day and year first above written.

Title I of ERISA pursuant to ERISA Sections 201(2), 301(a)(3) and 401(a)(1).

sole discretion, has designated those individuals eligible to participate in the
Plan.  Each individual so designated shall automatically become a participant
("Participant") as of the date determined by the Board.  Each Participant who
has commenced participation in the Plan shall continue to be a Participant until
he or she terminates his or her employment with the Company by reason of his or
her retirement, death, disability, resignation, dismissal or otherwise.
Notwithstanding the foregoing, the Board expressly reserves the right to remove
any Participant under the Plan from participation in the Plan at any time for
cause prior to the Participant's Retirement Date.  The persons designated as
Participants as of the Effective Date are those individuals set forth on Exhibit
"A" attached hereto and incorporated herein by this reference.

terminating on the first day of the 119th calendar month following the
Commencement Date (the "Pension Period"), the Company shall pay each Retiree an
amount equal to his Monthly Benefit.  In the event that the Retiree dies after
the Commencement Date, the Monthly Benefit shall be paid to the Beneficiary for
the remainder of the Pension Period.

  3.2  Death Benefit.  In the event that a Participant dies while he or she is
       -------------

           Beneficiary and the consent acknowledges the effect of the
           designation and is witnessed by an officer of the Company or a notary
           public, or it is established to the satisfaction of an officer of the
           Company that the consent required under this paragraph may not be
           obtained because there is no spouse, the spouse cannot be located, or
           such other circumstances as may be authorized by the Board.

                to his estate.

the Board may, in its sole discretion, elect to set aside amounts ("Reserves")

authority:

     (i)   To designate agents to carry out responsibilities relating to the
           Plan;

     (ii)  To administer, interpret, construe and apply this Plan and to answer
           all questions which may arise or which may be raised under this Plan
           by the Participant, Retiree, Beneficiary or other person whatsoever;

     (iii) To establish rules and procedures from time to time for the conduct

           necessary, appropriate, or convenient for the operation of the Plan.

   (c) Any action taken in good faith by the Board in the exercise of authority
conferred upon it by this Plan shall be conclusive and binding upon the
Participant, Retiree and Beneficiaries. All discretionary powers conferred upon
the Board shall be absolute.

  6.2  Limitation on Liability.  No employee or member of the Board shall be
       -----------------------                                              
subject to any liability with respect to his duties under the Plan unless the
person acts fraudulently or in bad faith.  To the extent permitted by law, the
Company shall indemnify each member of the Board, and any other employee of the
Company with duties under the Plan who was or is a party, or is threatened to be
made a party, to any threatened, pending or completed proceeding, whether civil,
criminal, administrative, or investigative, by reason of the person's conduct in

  7.1  Amendment and Termination.  The Company expects the Plan to be permanent,
       -------------------------                                                
but since future conditions affecting the Company cannot be anticipated or
foreseen, the Company reserves the right to amend, modify, or terminate the Plan

       ---------------------------------                                    
undertaking on the part of the Company and shall not be deemed to constitute a
contract between the Company and the Participant or to be consideration for, or
an inducement to, or a condition of, the employment of the Participant.  Nothing
contained in the Plan shall be deemed to give the right to the Participant to be
retained in the employ of the Company or to interfere with the right of the
Company to discharge the Participant at any time.

     No person shall have any right to any benefits under this Plan, except to
the extent expressly provided herein.
