ITEM 1.  BUSINESS

GENERAL DEVELOPMENT

     Plexus Corp., through its subsidiaries (together "Plexus" or the
"Company"), provides services relating to the design of electronic products and
assemblies; manufacture, programming and testing of such assemblies; and the
design and manufacture of related test equipment.  The Company's design and
production services are provided to customers under various arrangements.
Other than test equipment products, the Company does not design or manufacture
its own proprietary products.

     The Company's designed and manufactured products include printed circuit
boards, power supplies, telecommunications terminals, microprocessor-based
equipment, test equipment, electronic meters and intelligent burn-in chambers.
These products are used in a wide variety of manufactured goods, including
computers, telecommunications equipment, production and industrial control
equipment, medical equipment, word processing equipment and automobiles.

     Plexus is a Wisconsin corporation incorporated in 1979.  Its principle
subsidiaries are Electronic Assembly Corporation and Technology Group, Inc.
The Company also owns a minority equity interest in certain other companies.
The Company's principal office is located at 55 Jewelers Park Drive, Neenah,
Wisconsin 54957-0156, and its telephone number is (414) 722-3451.

ELECTRONIC PRODUCTS

     GENERAL BACKGROUND.  The Company's services involve the design of
electronic products and systems, the arrangement of electronic components
thereon, and the assembly and testing of such products including the
incorporation of the electronic assemblies into the final product housing.  The
products designed and assembled by the Company consist primarily of electronic
components assembled on printed circuit boards and programmed to perform
specific functions.  The electronic components include computer memory chips,
microprocessors, integrated circuits, resistors, capacitors, transformers, and
switches.  Printed circuit boards are the basic element in the manufacture of
most electronic products and act as the interconnection platforms for various
integrated circuits and electronic components.  In addition to the Company's
ability to design and manufacture complete electronic products, the Company
also has the capacity of designing and assembling printed circuitry products
and products utilizing circuit boards with multiple layers of circuitry.

     The various types of electronic product services offered by the Company
are discussed below.  A customer of the Company may utilize any or all of these
services.  The Company charges for these services under a variety of pricing
methods that vary accordingly to the customer or type of service involved.

     PRODUCT DESIGN.  The Company, primarily through its Technology Group, Inc.
subsidiary, provides product design and engineering services.  These services
include software development, circuit design, printed circuit board layout, and
product housing design.  The Company's design services provide customers with a
product which is capable of performing an intended function and which can be
manufactured in an efficient and economical manner.

     The Company's technologies involve the design of electronic systems,
including printed circuit boards and the arrangement of electronic components
thereon, and the development and/or programming of the application software
necessary to control the functions of those components.  The Company's
personnel design printed circuit boards using computer assisted design
equipment and software.  This equipment permits the design of complex
multi-layered printed circuit boards which not only have wiring on the top and
bottom surfaces but also incorporate multiple inside layers of circuitry.
<PAGE>   3

     The Company's design service may include initial feasibility studies,
product concept definition, development or specifications for product feature
and functions, product engineering specifications, microprocessor design,
design of circuit and custom or semi-custom computer chips, software
development, drafting, prototype production and testing, and development of
test specifications and procedures.

     PRODUCT MANUFACTURE.  The Company, primarily through its Electronic
Assembly Corporation subsidiary, manufactures electronic products and
assemblies for use in a wide variety of industries and applications.

     The  Company's assembly processes involve the fabrication of products from
components manufactured to specification by others.  Electronic components such
as memory chips, microprocessing units, integrated circuits, resistors,
capacitors, transformers, switches, wire and related items are purchased as
stock items from a variety of manufacturers and distributors.  The Company is
not dependent upon any single supplier for such material.  The Company's
printed circuit boards and certain other components are manufactured for it to
its customers' specifications.  The Company believes these products would be
available from a variety of sources and that the loss of any single source of
supply would not materially affect the Company's business.  However, the
Company did experience some shortages of memory and logic devices during fiscal
1994, which were a result of market-wide shortages of these devices.  The
Company believes that these shortages are not continuing.

     The Company's manufacturing operations include product assembly, testing,
and assembly into the final product housing.  While the Company has automated
various aspects of many processes, the assembly of components into electronic
products remains a labor-intensive process generally requiring a high degree of
precision and dexterity in the assembly stage and multiple quality control
checks prior to shipment.  The Company utilizes specially designed equipment
and techniques to maintain its ability to assemble efficiently a wide variety
of electronic products.

     PRODUCT TESTING.  The increasingly complex design and assembly techniques
for production of electronic products have created a need for the Company's
services in designing and assembling test equipment for electronic assemblies.
Such test equipment includes functional test fixtures for testing printed
circuit assemblies; in-circuit component measurement testers; and intelligent
burn-in chambers, which temperature cycle products under load.  The Company
designs and assembles test products for testing customers' products.

     The Company believes that the design and production of test equipment is
an important factor in its ability to provide products of consistent and high
quality.

     SMARTHOUSE PARTNERSHIP.  In fiscal 1990, SmartHouse, L.P. ("SHLP") became
a customer of the Company.  SHLP is a limited partnership affiliated with the
National Home Builders Association which is in the process of introducing an
energy and communications distribution system that enables home automation
through incorporating a new type of electrical wiring and gas piping that works
together with electronic components to allow electrical, gas, telephone,
coaxial and communication sub-systems and home appliances to be functionally
interactive.  The Company entered into a research and licensing ("R&L")
agreements with SHLP to develop a control center, which is the primary user
interface for the SmartHouse home automation system and for other
SmartHouse-related products.  Nationwide, consumer and builder acceptance of
the SmartHouse concept has been slower than anticipated.

     To finance certain expenditures relating to the development and design of
the Smart House-related products and to reduce its potential risk, the Company
has sponsored and invested in a research and development partnership, Plexus
Home Automation Limited Partnership ("PHALP"), of which a Plexus subsidiary is
general partner.  As part of PHALP's formation in 1992, Plexus transferred
rights and obligations under its R&L agreements with SHLP to PHALP, and PHALP
purchased the rights to prior related research from Plexus.  In fiscal 1995,
the Company made no additional investments in, and performed no services for,
the Partnership.





                                      -2-

OTHER BUSINESSES

     The Company also holds minority interests in certain other companies,
generally in related industries; the investments in these interests aggregated
$150,000 at September 30, 1995.  These investments are not material to the
overall success of the Company.

CUSTOMERS AND MARKETING

     The Company performs services for a wide variety of customers ranging from
large multi-national companies to smaller companies.  Because of the variety of
services it offers, its flexibility in design and manufacturing, and its
ability to timely respond to customer needs, the Company believes it is well
positioned to offer its services to customers in its market segments.  For many
customers, the Company functions as both a design and production arm, thus
permitting customers to concentrate on concept development and marketing and to
avoid the expense of development of manufacturing capacity.  This method
provides an economical and efficient alternative to in-house production.

     The Company markets its services primarily through its own employees.  It
also employs several sales representative agencies covering selected customer
accounts.  The representatives are paid commissions based upon sales.

     During fiscal 1995, the Company's services were sold to approximately 122
customers.  The customers include 5 subsidiaries or divisions of International
Business Machines Corporation ("IBM") and 4 subsidiaries or divisions of
General Electric Company ("GE"), all of which the Company considers separate
customers.  Other than IBM and GE, no customer accounted for as much as 10% of
the Company's fiscal 1995 sales.  Although sales to the various IBM and GE
subsidiaries, divisions and locations represented approximately 26% and 17%,
respectively, of the Company's total sales in fiscal 1995 (compared to 39% and
16%, respectively, in fiscal 1994), orders were received from the various
independent IBM and GE production facilities, each of which contracts
independently of the others.  In fiscal 1995, sales to IBM were reduced due to
the termination of Company services relating to particular IBM product lines,
although the Company remains an IBM supplier for several other product lines.
The Company believes that its sales to different IBM and GE locations are not
dependent on sales to other locations.  While the complete loss of either IBM
or GE as a customer would have a significant negative impact on the Company,
the Company does not believe the loss of all IBM or GE divisions to be a likely
possibility.

     The Company expects that its historic dependency on IBM and GE will be
further reduced in fiscal 1996 as a percentage of total sales.  However, the
Company expects revenue growth in fiscal 1996 from both IBM and GE, as well as
from expanded programs for other existing customers and programs from new
customers.

     Substantially all of Plexus' business is done on a project by project
basis for its customers.  Although Plexus has several projects and customers
for which it provides services on a continuing basis, the timing and nature of
particular customer projects can vary significantly from period to period.
Substantial changes in the nature or timing of these projects affect the
Company's sales and profitability from period to period.

COMPETITION

     The market for electronic products and services provided by the Company is
highly competitive, primarily on the basis of engineering, testing and
production capability, and the capacity for prompt delivery, quality and price.

     The capability to design in a timely manner and the capacity to produce
quality items and to assure prompt delivery are particularly important in the
electronics industry.  The average product designed and assembled by the
Company has a technologically useful life of only 18 months to three years.
Through its design





                                      -3-
<PAGE>   5
and production services, the Company serves as an extension or replacement for
its customers' engineering, testing and manufacturing operations.

     Competitors in the electronics design and assembly field are numerous and
range in size from several very large multi-national companies with
substantially greater resources than the Company to many smaller companies
competing only in specific aspects of the Company's business.  The Company also
"competes" against companies which determine to manufacture items in-house
rather than contract with a third-party manufacturer.  The Company estimates
that it controls approximately two percent of the domestic market in the
outsourced electronics manufacturing services industry.

EMPLOYEES

     As of December 1, 1995, the Company employed full time approximately 2,350
persons.  These employees included approximately 254 professional and
engineering employees and approximately 1,596 employees who work in assembly.
The Company has never experienced a work stoppage due to a labor dispute,
considers its relations with employees to be very good, and is not a party to
any labor contract.  To date, the Company has not  had any difficulty
fulfilling its employment needs.

PATENTS AND TRADEMARKS

     The Company does not own any material patents or copyrights.  The Company
owns the servicemark "Plexus".  Also, the Company has a non- exclusive license
in system technology for SmartHouse, L.P. (see "SmartHouse Partnership" above).

ENGINEERING, TESTING AND DEVELOPMENT

     The Company believes that its engineering, testing and development
capabilities are significant factors in the success of its business.  The
Company maintains a design team of 118 employees, including 102 hardware and
software design engineers and support staff, and utilizes an integrated design
system in the Company's engineering services.  See also "SmartHouse
Partnership" above regarding the use of a research and development partnership
to finance the Company's development of SmartHouse-related products.

MATERIALS AND COMPONENTS

     The Company does not generally fabricate the component parts which it uses
for the products which it assembles.  However, the Company uses various
component parts which are manufactured by others.  Important components include
integrated circuits, resistors, capacitors and printed circuit boards; these
components may be either custom or standard.  The Company has numerous
suppliers for these components and has generally not experienced difficulties
obtaining the components needed for its assemblies.  However, beginning in late
fiscal 1993, there has been an industry-wide shortage of certain component
parts (semiconductor devices) which has resulted in some delayed deliveries and
higher prices to the Company (and to other companies in related industries).

ENVIRONMENTAL COMPLIANCE

     The Company believes that it is in compliance with all federal, state and
local environmental laws, and does not anticipate any significant expenditures
in maintaining its compliance.

ITEM 2.    PROPERTIES

     The Company owns its headquarters, the Plexus Technology Center, in
Neenah, Wisconsin, which consists of approximately 45,000 square feet and
includes Plexus' headquarters office.  The Technology Center provides office,
design and testing space for the Company.

     Three of the Company's manufacturing facilities are located at Neenah,
Wisconsin, and the fourth at Richmond, Kentucky.  The facilities in the
original Neenah complex, which are owned by the Company and were built in the
period from 1980 to 1985, contain an aggregate of approximately 80,000 square
feet of assembly and office space.  The two Wisconsin facilities owned by the
Company (the headquarters and the original manufacturing complex) are subject
to mortgages securing the Company's bank debt.

     In 1990, the Company occupied an additional assembly facility in Neenah,
Wisconsin, with approximately 110,000 square feet of assembly and office space,
which provides additional capacity.  The Company leases this facility under a
fifteen year lease.

     In January 1994, the Company occupied a new surface mount assembly
facility in Neenah, Wisconsin. This facility is approximately 175,000 square
feet, and is used for manufacturing purposes.  The Company leases the facility
under a twenty year lease.

     In 1985, the Company opened an assembly facility with approximately 45,000
square feet of assembly and office space, which it owns in Richmond, Kentucky.

     The Company also uses substantial specialized equipment in its operations.
The Company leases a substantial amount of this equipment.  Equipment owned by
the Company is pledged to secure bank debt.

     The Company believes that its equipment and facilities are modern, well
maintained and adequate for its present needs.  However, continued expansion of
the Company's business may require additional facility expansion in the future.

ITEM 3.    LEGAL PROCEEDINGS

     There are no material pending legal proceedings to which the Company is a
party or of which any of its property is the subject.

ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of security holders during the fourth
quarter of fiscal 1995.

Report of Independent Accountants



To the Shareholders and

  Board of Directors

Plexus Corp.:

We have audited the accompanying consolidated balance sheets of
Plexus Corp. and Subsidiaries as of September 30, 1995 and 1994,
and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years
in the period ended September 30, 1995.  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 Plexus Corp. and Subsidiaries as of
September 30, 1995 and 1994, and the consolidated results of
their operations and their cash flows for each of the three
years in the period ended September 30, 1995, in conformity with
generally accepted accounting principles.

PLEXUS CORP. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  SIGNIFICANT ACCOUNTING POLICIES:
           
    a.  Consolidation Principles:  The consolidated financial statements include
    the accounts of Plexus Corp. and its subsidiaries, all of which are
    wholly-owned.  All significant intercompany transactions have been
    eliminated.
            
    b.  Inventories:  Inventories are valued primarily at the lower of
    standard cost or market.  Standard cost approximates costs determined by the
    first-in, first-out (FIFO) method.

    c.  Property, Plant and Equipment and Depreciation:  These assets
    are stated at cost.  Depreciation, determined on the straight-line method,
    is based on lives assigned to the major classes of depreciable assets as
    follows:

<TABLE>
                   <S>                                         <C>
                   Buildings and improvements                  18-40 years
                   Machinery and equipment                      3-10 years
                   Office furniture and equipment               5-10 years
                   Vehicles                                     3-5  years
</TABLE>



    d.  Revenue Recognition:  Revenue is recognized primarily when      
    inventory is shipped.  Revenue relating to product design and development
    contracts is recognized as costs are incurred utilizing the
    percentage-of-completion method.

    e.  Income Taxes:  Deferred income taxes are provided for   
    differences between the bases of assets and liabilities for financial and
    tax reporting  purposes.

    f.  Stock Options:  Proceeds from the sale of newly issued common stock to
    employees under the Company's stock option plan are credited to common stock
    to the extent of par value and the excess to additional paid-in-capital. 
    Income tax benefits attributable to stock options exercised are recorded as
    an increase in additional paid-in-capital.

    g.  Net Income Per Common and Common Equivalent Share:  The computations of
    primary and fully diluted net income per common share for 1995 and 1994 are
    based upon the weighted average number of common shares outstanding plus the
    effect of common shares contingently issuable relating to outstanding stock
    options using the treasury stock method and common shares contingently
    issuable relating to the convertible preferred stock using the if-converted
    method.  In 1993, stock options did not impact net income per share as they
    were either insignificant or antidilutive, thus the computations are based
    solely upon the weighted average number of common shares outstanding during
    the period.  The fully diluted calculation reflects additional dilution from
    stock options and convertible preferred shares applying the market price at
    the end of the period when that price is higher than the average market
    price for the period.

    The common equivalent shares outstanding for the calculation of primary
    and fully diluted net income per common share were 7,137,487 and 7,249,286
    in 1995, respectively.  In 1994, and 1993, the common equivalent shares
    outstanding for the calculation of primary and fully diluted net income per
    common share were 6,705,239, and 6,448,173, respectively.

The revolving credit arrangement matures in July 1998 and provides for
maximum borrowings of $55,000,000, with all or a portion of the principal
bearing interest at a prime based or a LIBOR based rate as elected by the
Company.   These rates range from prime plus 1/4% to prime plus 1/2% and LIBOR
plus 2% to LIBOR plus 2 1/2%, depending on the Company's consolidated debt to
worth ratio, as defined by the Loan Agreement.  The weighted average interest
rate for this agreement was 7.7% at September 30, 1995.  The amount available
under this agreement is limited to 80% of qualified accounts receivable and 50%
of qualified inventory.  Inventory borrowings are limited to $27,500,000.  A
commitment fee of 1/4 of 1% per annum on the unused portion of this arrangement
is payable quarterly.

During 1995, the Company has an interest rate cap agreement with a
commercial bank which limited the Company's interest rate on a portion of its
floating rate long-term debt to 8% or 8.5%, depending on the rate charged on the
revolving credit arrangement.  The agreement had a notional amount of
$10,000,000 and expires on October 7, 1996.

The revolving credit agreement, as amended, includes covenants  which require
the maintenance of various debt to net worth ratios.

The aggregate scheduled maturities of long-term debt in subsequent years

    Cash  paid for income taxes for the years ended September 30,
    1995, 1994 and 1993 was $4,577,000, $1,419,000 and $1,884,000,
    respectively.



6.  STOCKHOLDERS' EQUITY:

    During 1994, the company issued 7,000 shares of Series A Preferred Stock
    (the "Preferred Shares") with a face value of $1,000 per share at face
    value.  Dividends are earned on the face value of the Preferred Shares at
    1/2 the sum of the prime rate less 1%.  These dividends are cumulative and  
    payable semi-annually in arrears, when and as declared by the Company's
    Board of Directors.  At September 30, 1995, dividends of $8.25 per share
    (aggregate $58,000) were in arrears on the Preferred Shares.  Upon
    liquidation of the Company, holders of the Preferred Shares would be
    entitled to receive the face value of the Preferred Shares, plus any accrued
    but unpaid dividends, whether declared or not, before any distribution to
    the common shareholders of the Company.  The Company may redeem the
    Preferred Shares at any time on or after June 30, 1995, at face value plus
    any accrued but unpaid dividends, whether declared or not.  From and after
    October 1, 1994 until June 30, 2004, the Preferred Shares are convertible
    into common stock at a conversion price of $12.63 per share.  The Company
    has reserved 554,455 shares of its authorized but unissued common stock for
    possible conversion.

7.  LEASE COMMITMENTS:

    The Company has a number of operating lease agreements primarily            
    involving manufacturing equipment, computerized design equipment and
    manufacturing facilities.  These leases are noncancelable and expire on
    various dates through 2014.  Rent expense under all operating leases during
    1995, 1994 and 1993 was approximately $12,491,090, $10,519,000 and
    $7,742,000, respectively.  Renewal and purchase options are available on
    certain of these leases.

    During 1994, the Company sold its Advanced Manufacturing Facility for
    $9,250,000 and entered into an agreement to lease the facility back from
    the purchaser.  The lease calls for annual rental payments of $1,091,000
    over twenty years and allows the Company to extend the lease for six
    five-year periods.  The lease has been accounted for as an operating lease. 
    The gain recognized on the sale was not significant.

    The future minimum annual payments on these leases are as follows (in
    thousands):

8.  STOCK OPTION AND SAVINGS PLANS:

    The Company's 1988 Stock Option Plan (the "1988 Plan") authorizes the
    Company to grant options to purchase up to 900,000 shares of common stock. 
    All shares will be made available from authorized and unissued shares. 
    Officers and key employees of the Company are eligible to receive options. 
    The 1988 Plan provides for the granting of options at an option price of
    not less than the fair market value on the date of grant.  Options vest
    over a three year period. Additionally, the 1988 Plan authorizes the
    Company to grant 450,000 stock appreciation rights, none of which have been
    granted as of September 30, 1995.

8.  STOCK OPTION AND SAVINGS PLANS, CONTINUED:

    During  1995, the Company approved two stock option plans, the  1995
    Executive Stock Option Plan (the "Executive Plan") and the 1995 Directors'
    Stock Option Plan (the "Directors' Plan).  The Executive Plan authorizes
    the Company to grant options to purchase up to 1,000,000 shares of
    common stock. All shares will be made available from authorized and
    unissued  shares.  Options may be granted to officers and key employees of
    the Company provided that no officer or key employee may be granted an
    option or options covering, in the aggregate, more than 50,000 shares of
    stock in any calendar year.  The Executive Plan provides for the granting
    of options at an option price of not less than the fair market value on the
    date of grant.  Options vest over a three year period after the date of
    grant. Additionally, the  Executive Plan authorizes the Company to grant
    300,000 stock appreciation rights, none of which have been granted as of
    September 30, 1995.  The Executive Plan shall terminate on December 31,
    2004 or at such earlier time as the Board of Directors may determine.

    The Directors' Plan authorizes the Company to grant options to  purchase up
    to 100,000 shares of common stock. Shares may come from authorized but
    unissued shares, from treasury shares held by the Company, from shares
    purchased by the Company on an open market for such purpose, or from any
    combination of the foregoing.  At the first meeting of the Board of
    Directors following the Company's 1995 annual meeting of shareholders, each
    person then serving the Company as an outside director was granted a
    nonqualified stock option to purchase 1,500 shares. Commencing December 1,
    1995, and continuing on the first business day of each December thereafter
    through December 1, 2004, each person then serving the Company as an
    outside director shall automatically be granted a nonqualified stock option
    to purchase 1,500 shares.  The Directors' Plan provides for the granting of
    options at an option price of not less than the fair market value on the
    date of grant and  shall terminate on December 31, 2004 or at such earlier
    time as the Board may determine.

    Stock option balances and transactions under the 1988 Plan, the Executive
    Plan, and the Directors' Plan at and during the years ended September 30,
    1995, 1994, and 1993 are summarized as follows:

8.  STOCK OPTION AND SAVINGS PLANS, CONTINUED:

    Options outstanding as of September 30, 1995 have exercise prices ranging   
    from $2.54 to $17.44 per share.

    The Company's 401(k) savings plan covers all employees with one or more
    years of service.  The Company matches employee contributions up to 2.5% of
    eligible earnings.  The Company's contributions for 1995, 1994 and 1993
    totaled $644,000, $563,000 and $498,000, respectively.

    The Company is not obligated to provide any postretirement medical or life  
    insurance benefits to employees.



9.  BUSINESS SEGMENT AND MAJOR CUSTOMERS:

    The Company and its subsidiaries operate in one business segment, the
    production and sale of electronic products including the designing, 
    manufacturing, programming and testing of computerized electronic
    assemblies.

    Approximate sales to various divisions of a major customer were 25.6%,
    39.4% and 36.6% of consolidated net sales for the years ended September 30,
    1995, 1994 and 1993, respectively. Additionally, sales to various
    divisions of another major customer approximated 17.3%, 15.6% and 18.7% of
    consolidated net sales for the years ended September 30, 1995, 1994 and
    1993, respectively.



10. TRANSACTIONS WITH RELATED PARTIES:

    During 1993 and 1992, a wholly-owned subsidiary of the Company, Plexus
    General Partner Corp., made capital contributions totaling $700,000 to the
    Plexus Home Automation Limited Partnership ("PHALP").  Several of the
    limited partners of PHALP are officers, directors and/or shareholders of
    the Company and/or other Company subsidiaries.  The Company recorded
    losses of $413,000 in the years 1993 through 1995 which reduced the
    carrying value of this investment.  PHALP became inactive during the latter
    half of 1995 and as a result the Company wrote off its remaining investment
    in the partnership of $57,000 and certain other related assets of $180,000. 
    The Company billed PHALP $41,000, $65,000 and $693,000, during the years
    1995, 1994 and 1993, respectively, for certain services rendered by the
    Company.

    During 1994, promissory notes aggregating $5,000,000, which were payable to
    certain shareholders of the Company who are also limited partners in PHALP,
    were paid in full with the proceeds from the issuance of the Series A
    Preferred Stock.  The preferred shares were issued to and are held by the
    former holders ofthe promissory notes described above.

    (*) Income per common share is computed independently for each  quarter. 
    The annual per share amount may not equal the sum of the quarterly amounts
    due to rounding.  The amounts shown for 1994 represent primary and
    fully diluted earnings per common share.

    The Company recognized adjustments in the fourth quarter of 1995 and  1994
    related principally to the adjustment of perpetual inventory records to     
    actual balances which decreased and increased quarterly earnings per
    share by $(.02) and $0.05, respectively.

Gentlemen:

                 Electronic Assembly Corporation, a Wisconsin corporation (the
"Company"), hereby agrees with you as follows:

                 1.       Definitions.  Reference is made to the Revolving
Credit Agreement dated as of April 18, 1991, as amended through Amendment No. 9
thereto dated as of August 1, 1994 (the "Loan Agreement") between the Company
and each of you, pursuant to which the Company has issued its revolving credit
notes, each dated July 30, 1993, in the aggregate principal amount of
$40,000,000 (the "Existing Notes").  All capitalized terms used and not
otherwise defined herein shall have the meanings given to such terms by the
Loan Agreement as supplemented and amended hereby.

                 2.       Extension of Commitment Period.  The Company has
requested that the Banks agree to extend the Termination Date and the final
maturity of the Existing Notes from July 30, 1996 to July 31, 1997.  The Banks
are willing to grant such extension subject to all of the terms and conditions
hereof.  Any additional loans made pursuant to the revolving credit as so
extended, together with the unpaid balance of the Existing Notes, shall be
evidenced by new promissory notes of the Company in the form of Exhibit A
annexed hereto (the "New Notes") to be dated as of the date hereof, in the
amounts of the Banks' respective Commitments, which shall be executed by the
Company and delivered to the Banks against the return of the Existing Notes to
the Company.  Accrued interest on the Existing Notes outstanding on the date of
issuance of the New Notes shall be included in interest due on the New Notes on
the first interest payment date specified therein.
<PAGE>   2


                 3.       Amendments to Loan Agreement.  Upon issuance of the
New Notes, the Loan Agreement shall be amended as of the date hereof as
follows:

                 (a)      All references in the Loan Agreement to the Notes
         issued thereunder and the loans evidenced thereby shall refer to the
         New Notes issued hereunder and the loans evidenced thereby (including
         the unpaid balances of the Existing Notes).

                 (b)      All references to the Loan Agreement in the Loan
         Agreement and in any related agreements shall refer to the Loan
         Agreement as amended hereby.


                 (c)      The date of July 30, 1996 set forth in Section 1.38
         of the Loan Agreement ("Termination Date") shall be amended to July
         31, 1997.

                 4.       Representations and Warranties.  The Company repeats
and reaffirms the representations and warranties set forth in Section 3 of the
Loan Agreement as of the date hereof, except that the representations in
Section 3.2 of the Loan Agreement are hereby made with respect to the audited
consolidated financial statements of Plexus Corp. as of September 30, 1994.
The Company also represents and warrants that the execution, delivery and
performance of this Amendment are within the corporate powers of the Company,
have been duly authorized by all necessary corporate action and do not and will
not (i) violate any provision of the articles of incorporation or by-laws of
the Company or of any law, rule, regulation, order or judgment presently in
effect having applicability to the Company; (ii) require the consent or
approval of, or filing or registration with, any governmental body, agency or
authority; or (iii) result in any breach of or constitute a default under any
indenture or other agreement or instrument under which the Company or any
Subsidiary is a party or by which it or its properties may be bound or
affected.

                 5.       Conditions.  Without limiting any of the other terms
of the Loan Agreement as amended hereby, this Amendment shall not become
effective, and the Banks shall not be required to make any further loans to the
Company unless and until:

                          (a)     No Default or Event of Default shall have
         occurred and be continuing after giving effect to this Amendment and
         neither the business nor the assets nor the financial condition of the
         Company or any Guarantor shall have been materially adversely affected
         as the result of any event or development since September 30, 1994;
         and

                          (b)     All proceedings taken in connection with the
         transactions contemplated by this Amendment and all instruments,
         authorizations and other documents applicable thereto shall be
         satisfactory in form and

         substance in the reasonable opinion of the Banks and their counsel.

                 6.       Confirmation of Loan Agreement, etc.  Except as
expressly provided above, the Loan Agreement and the other agreements related
thereto shall remain in full force and effect.

                 7.       Fees and Expenses.  The Company shall be responsible
for the payment of all fees and out-of-pocket disbursements reasonably incurred
by the Banks in connection with the preparation, execution, delivery,
administration and enforcement of this Amendment including without limitation
the reasonable fees and disbursements of counsel for the Banks, whether or not
any transaction contemplated by this Amendment is consummated.

                 8.       Governing Law.  This Amendment shall be governed by
and construed in accordance with the laws (other than the conflict of laws
rules) of the State of Wisconsin.

                 9.       Counterparts.  This Amendment may be signed in any
number of counterparts with the same effect as if the signatures thereto any
hereto were upon the same instrument.

MANAGEMENT'S DISCUSSION AND ANALYSIS
of Financial Condition and Results of Operations

YEAR ENDED SEPTEMBER 30, 1995 COMPARED TO
YEAR ENDED SEPTEMBER 30, 1994

Net sales for the fiscal year ended September 30, 1995 increased $40,651,000 or
16.7% to $283,134,000 from $242,483,000 for the fiscal year ended September 30,
1994.  After a slow first quarter, volume increased steadily during fiscal year
1995, due to an increased customer base.  Management believes that these new
strategic relationships are a result of the Company's investment and
development of its outstanding technology package and facilities.  The Company
will continue to be selective in the enlargement of its customer base, seeking
market leaders that want to develop a long-term relationship.  A portion of
this increase continues to be sales allocable to component parts used in
assemblies ("part sales") as distinguished from sales allocable to services;
parts sales tend to have lower margins to the Company than services sales.

Cost of sales for the fiscal year ended September 30, 1995 increased
$33,125,000 or 14.6% to $259,438,000 from $226,313,000 for the fiscal year
ended September 30, 1994.  The increase in costs of sales results from the
increased level of sales and from those costs associated with increased parts
sales.  Increased utilization of the Advanced Manufacturing Center and more
efficient use of capacity in the other plants enabled gross profit to increase
$7,526,000 or 46.5% for the fiscal year ended September 30, 1995 to $23,696,000
from $16,170,000 for the fiscal year ended September 30, 1994.  Gross profit
margin as a percentage of sales increased to 8.4% from 6.7%.

Selling and administrative expenses for the fiscal year ended September 30,
1995 increased $3,017,000 to $11,261,000 from $8,244,000 for the fiscal year
ended September 30, 1994.  This increase is due to management's decision to
improve customer service, data collection, and information systems with
additional staffing.  The Company also incurred  larger than normal
expenditures during the fourth quarter of the fiscal year for group health,
employee procurement, supplies, customer relations, and charitable donations.
These events caused an increase in selling and administrative expenses to 4.0%
for fiscal 1995 as a percentage of net sales compared to 3.4% for fiscal 1994.

Interest expense decreased $682,000 for the fiscal year ended September 30,
1995 to $2,470,000 from $3,152,000 for the fiscal year ended September 30,
1994.  This decrease is due to decreases in the amount of average daily
borrowings on the Company's line of credit related to working capital
requirements in the latter half of the fiscal year and decreases in interest
rates.  Miscellaneous income of $317,000 for fiscal year 1995 compared to
miscellaneous income of $156,000 was due to increased amount of charges billed
back to customers covering inventory carrying costs, and the one-time effect of
a write-off in fiscal 1994.

Income taxes increased $2,066,000 for the fiscal year ended September 30, 1995
to $3,939,000 from $1,873,000 for the fiscal year ended September 30, 1994.
This increase is due to the increased level of pretax profits.

The Company's two largest customers in sales in each of the past several years
were International Business Machines Corporation (through up to six
subsidiaries or divisions) and General Electric Company (through up to five
subsidiaries or divisions).  Each of the entities contracts independently of
the others, and the Company does not believe that sales to any of these
customers depend upon sales to the others.  In fiscal 1995, sales to
International Business Machines Corporation were reduced due to the termination
of several projects relating to IBM product lines, although IBM remains a
significant customer.  While the loss of all, or a substantial portion of, the
business with IBM or General Electric would have a material adverse effect on
the Company's sales and profitability, the Company does not believe this to be
a likely possibility.  The Company expects that its historic dependency on IBM
and GE will be further reduced in fiscal 1996 as a percentage of total sales.
The Company expects, however,  revenue growth in fiscal 1996 from both IBM and
GE, as well as from expanded programs for other existing customers and programs
from new customers.

Substantially all of the Company's business is done on a project by project
basis for its customers.  Although the Company has several projects and
customers for which it provides services on a continuing basis, the timing and
nature of particular customer projects can vary significantly from period to
period. Substantial changes in the nature or timing of these projects can
affect the Company's sales and profitability from period to period.

YEAR ENDED SEPTEMBER 30, 1994 COMPARED TO
YEAR ENDED SEPTEMBER 30, 1993

During the year ended September 30, 1994, net sales increased $82,886,000 or
52% to $242,483,000 from $159,597,000 for the fiscal year ended September 30,
1993.  This increase was made possible due to increased capacity provided by
the Company's new Advanced Manufacturing Center which was completed and began
operations during the beginning of fiscal year 1994.  The largest portion of
this increase related to part sales as distinguished from sales allocable to
services.

Cost of sales increased $79,790,000 to $226,313,000 for the fiscal year ended
September 30, 1994 compared to $146,523,000 for the fiscal year ended September
30, 1993.  Approximately 86% of this increase was in the cost of component
parts associated with the increase in parts sales, with the balance of the
increase arising from other expenses such as labor and related payroll costs
due to increase staffing, and fixed manufacturing expenses related to the
Advanced Manufacturing Center.  As a result of the increased parts sales,
increased cost of key component parts especially during the first fiscal
quarter resulting from a worldwide shortage of key components (logic and memory
devices), increased staffing and fixed manufacturing expenses, gross profit
decreased to 6.7% of net sales for the fiscal year ended September 30, 1994
compared to 8.2% of net sales for the fiscal year ended September 30, 1993.
However actual gross profit increased 23.6% to $16,170,000 in fiscal 1994 from
$13,074,000 for fiscal year 1993 as a result of the increased sales.

MANAGEMENT'S DISCUSSION AND ANALYSIS
of Financial Condition and Results of Operations

Selling and administrative expenses as a percentage of net sales decreased to
3.4% for the fiscal year ended September 30, 1994 compared to 4.2% of net sales
for the fiscal year ended September 30, 1993.  Selling and administrative
expenses are expected to remain at a level relatively consistent with the
fourth quarter of fiscal 1994 as the Company believes it has in place the
structure and personnel, with the possible addition of one or two positions, to
support increased  sales.

Other income and expense increased $816,000 to $2,996,000 for the fiscal year
ended September 30, 1994 compared to $2,180,000 for the fiscal year ended
September 30, 1993.  Interest expense increased $1,544,000 to $3,152,000 from
$1,608,000 for the fiscal year ended September 30, 1993.  The increase in
interest expense in fiscal year 1994 is due to increased average daily
borrowings on the Company's line of credit related to working capital
requirements and also higher interest rates.  The Company's increased interest
expense on its line of credit was offset in part by the Company's sale and
leaseback transaction in late fiscal 1994 as detailed below.  Miscellaneous
income of $156,000 for fiscal year 1994 compared to miscellaneous expense of
$572,000 for fiscal year 1993 primarily relating to write-off of a minority
investment and an allocated loss on the Company's investment in Plexus Home
Automation Limited Partnership.

Income taxes for the fiscal year ended September 30, 1994 increased $313,000 to
$1,873,000 primarily due to increased pretax profit.  Effective October 1, 1992
the Company adopted Statement of Financial Accounting Standards No. 109
"Accounting for Income Taxes".  This change did not have a significant effect
on reported net earnings for the fiscal year 1994 or 1993.

LIQUIDITY AND CAPITAL RESOURCES

As shown in the Company's statements of cash flows, cash increased $2,488,000
during fiscal 1995.  This increase is a result of $4,188,000 provided by
operations and $387,000 provided by financing activities, offset by $2,087,000
used in investing activities.  Net cash provided by operations is a result
primarily from net income, non-cash items and improved controls over inventory,
offset by decreased accounts payable and increased accounts receivables.  Net
cash used in investing activities is a result primarily from purchase of
equipment.

Working capital increased to $71,302,000 at September 30, 1995 from $62,784,000
at September 30, 1994.  Accounts receivable increased $3,861,000 because of
increased sales volume for the year.  Inventories decreased $11,081,000 as a
result of improved procurement and materials management initiatives.
Management expects to make additional progress on improving cash flow from
operations.

The Company leases the majority of its machinery and equipment additions under
operating lease arrangements.  The Company anticipates continued use of lease
financing arrangements as a means to finance machinery and equipment.  The
Company believes that anticipated revenues from operations will be sufficient
to fund these obligations for the foreseeable future.  The Company has total
future commitments of $46,476,000 related to noncancelable operating leases
(see Note 7 to the Consolidated Financial Statements); lease payments are
included in cost of goods sold.

Payment for property, plant and equipment for fiscal 1995, 1994 and 1993 was
$2,106,000, $5,288,000, and $8,233,000, respectively.  Except for the Advanced
Manufacturing Center, these acquisitions were financed from working capital.
The Advanced Manufacturing Center was permanently financed by use of a sale and
leaseback transaction in August, 1994.  Management has currently budgeted
capital expenditures in fiscal year 1996 of approximately $2,000,000.

The Company's debt-to-equity ratio was 1.8 to 1 at September 30, 1995 and 2.5
to 1 at September 30, 1994.  The Company was in compliance with debt-to-equity,
and similar ratios, under its debt facilities at both dates.

At September 30, 1995, the Company had $41,500,000 outstanding on its Revolving
Credit Facility, as compared to $37,100,000 at September 30, 1994.  The Company
increased this Revolving Credit Facility in July 1995, to permit maximum
borrowings of $55,000,000 (increased from $40,000,000) and extended the
termination date and final maturity of the existing notes from July 31, 1997 to
July 31, 1998.  The Company used $3,500,000 of the additional credit to pay off
an outstanding $3,500,000 promissory note to a financial institution which it
had used to replace certain Industrial Revenue Bond debt.  The Company also
paid off its $200,000 industrial revenue bond for its Kentucky facility.  On
October 7, 1993, the Company entered into an interest rate cap agreement which
limits the interest rate portion of its floating rate long term debt to 8% or
8.5%, depending on the rate charged in the revolving credit agreement.  The
agreement has a notional amount of $10,000,000 and expires on October 7, 1996.
The Company does not believe that these arrangements create any material
exposure to the Company relating to "derivatives" or similar arrangements.

The Company has not paid dividends on its common stock, but has reinvested its
earnings to support its working capital and expansion requirements.  Except for
future dividend requirements on the Series A preferred stock, the Company
intends to continue to employ its earnings in the development and expansion of
the business and does not expect to pay cash dividends in the foreseeable
future.

The Company believes that its existing credit facilities, leasing capabilities,
and projected cash flow from operations will be sufficient to meet its
foreseeable short term and long term capital and liquidity needs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES:

Consolidation Principles: The consolidated financial statements include the
accounts of Plexus Corp. and its subsidiaries, all of which are wholly-owned.
All significant intercompany transactions have been eliminated.

Inventories: Inventories are valued primarily at the lower of standard cost or
market. Standard cost approximates costs determined by the first-in, first-out
(FIFO) method.

Property, Plant and Equipment and Depreciation: These assets are stated at
cost. Depreciation, determined on the straight-line method, is based on lives
assigned to the major classes of depreciable assets as follows:

    Buildings and improvements            18-40 years
    Machinery and equipment                3-10 years
    Office furniture and equipment         5-10 years
    Vehicles                                3-5 years

Revenue Recognition: Revenue is recognized primarily when inventory is shipped.
Revenue relating to product design and development contracts is recognized as
costs are incurred utilizing the percentage-of-completion method.

Income Taxes: Deferred income taxes are provided for differences between the
bases of assets and liabilities for financial and tax reporting purposes.

Stock Options: Proceeds from the sale of newly-issued common stock to employees
under the Company's stock option plan are credited to common stock to the
extent of par value and the excess to additional paid-in-capital.  Income tax
benefits attributable to stock options exercised are recorded as an increase in
additional paid-in-capital.

Net Income Per Common and Common Equivalent Share: The computations of primary
and fully diluted net income per common share for 1995 and 1994 are based upon
the weighted average number of common shares outstanding plus the effect of
common shares contingently issuable relating to outstanding stock options using
the treasury stock method and common shares contingently issuable relating to
the convertible preferred stock using the if-converted method. In 1993, stock
options did not impact net income per share as they were either insignificant
or antidilutive, thus the computations are based solely upon the weighted
average number of common shares outstanding during the period. The fully
diluted calculation reflects additional dilution from stock options and
convertible preferred shares applying the market price at the end of the period
when that price is higher than the average market price for the period.

The common equivalent shares outstanding for the calculation of primary and
fully diluted net income per common share were 7,137,487 and 7,249,286 in 1995,
respectively.  In 1994, and 1993, the common equivalent shares outstanding for
the calculation of primary and fully diluted net income per common share were
6,705,239, and 6,448,173, respectively.

Reclassification: Certain prior years' amounts have been reclassified to
conform to the 1995 presentation.

The revolving credit arrangement matures in July 1998 and provides for maximum
borrowings of $55,000,000, with all or portion of the principal bearing
interest at a prime-based or a LIBOR-based rate as elected by the Company.
These rates range from prime plus 1/4% to prime plus 1/2% and LIBOR plus 2% to
LIBOR plus 2 1/2%, depending on the Company's consolidated debt-to-worth ratio,
as defined by the Loan Agreement. The weighted average interest rate for this
agreement was 7.7% at September 30, 1995. The amount available under this
agreement is limited to 80% of qualified accounts receivable and 50% of
qualified inventory. Inventory borrowings are limited to $27,500,000. A
commitment fee of 1/4 of 1% per annum on the unused portion of this arrangement
is payable quarterly.

During 1995, the Company has an interest rate cap agreement with a commercial
bank which limited the Company's interest rate on a portion of its floating
rate long-term debt to 8% or 8.5%, depending on the rate charged on the
revolving credit arrangement. The agreement had a notional amount of
$10,000,000 and expires on October 7, 1996.

The revolving credit agreement, as amended, includes covenants which require
the maintenance of various debt-to-net worth ratios.

The aggregate scheduled maturities of long-term debt in subsequent years are as

Cash paid for income taxes for the years ended September 30, 1995, 1994 and
1993 was $4,577,000, $1,419,000 and $1,884,000, respectively.

NOTE 6 - STOCKHOLDERS' EQUITY:

During 1994, the company issued 7,000 shares of Series A Preferred Stock (the
"Preferred Shares") with a face value of $1,000 per share at face value.
Dividends are earned on the face value of the Preferred Shares at 1/2 the sum
of the prime rate less 1%. These dividends are cumulative and payable
semi-annually in arrears, when and as declared by the Company's Board of
Directors. At September 30, 1995, dividends of $8.25 per share (aggregate
$58,000) were in arrears on the Preferred Shares. Upon liquidation of the
Company, holders of the Preferred Shares would be entitled to receive the face
value of the Preferred Shares, plus any accrued but unpaid dividends, whether
declared or not, before any distribution to the common shareholders of the
Company. The Company may redeem the Preferred Shares at any time on or after
June 30, 1995, at face value plus any accrued but unpaid dividends, whether
declared or not. From and after October 1, 1994 until June 30, 2004, the
Preferred Shares are convertible into common stock at a conversion price of
$12.63 per share. The Company has reserved 554,455 shares of its authorized but
unissued common stock for possible conversion.

NOTE 7 - LEASE COMMITMENTS:

The Company has a number of operating lease agreements primarily involving
manufacturing equipment, computerized design equipment and manufacturing
facilities. These leases are noncancelable and expire on various dates through
2014. Rent expense under all operating leases during 1995, 1994 and 1993 was
approximately $12,491,090, $10,519,000 and $7,742,000, respectively. Renewal
and purchase options are available on certain of these leases.

During 1994, the Company sold its Advanced Manufacturing Facility for
$9,250,000 and entered into an agreement to lease the facility back from the
purchaser. The lease calls for annual rental payments of $1,091,000 over twenty
years and allows the Company to extend the lease for six five-year periods. The
lease has been accounted for as an operating lease. The gain recognized on the
sale was not significant.

The future minimum annual payments on these leases are as follows (in
thousands):

Notes to Consolidated Financial Statements

granted to officers and key employees of the Company provided that no officer
or key employee may be granted an option or options covering, in the aggregate,
more than 50,000 shares of stock in any calendar year. The Executive Plan
provides for the granting of options at an option price of not less than the
fair market value on the date of grant. Options vest over a three-year period
after the date of grant. Additionally, the Executive Plan authorizes the
Company to grant 300,000 stock appreciation rights, none of which have been

December 31, 2004 or at such earlier time as the Board of Directors may
determine.

The Directors' Plan authorizes the Company to grant options to purchase up to
100,000 shares of common stock. Shares may come from authorized but unissued
shares, from treasury shares held by the Company, from shares purchased by the
Company on an open market for such purpose, or from any combination of the
foregoing. At the first meeting of the Board of Directors following the
Company's 1995 annual meeting of shareholders, each person then serving the
Company as an outside director was granted a nonqualified stock option to
purchase 1,500 shares. Commencing December 1, 1995, and continuing on the first
business day of each December thereafter through December 1, 2004, each person
then serving the Company as an outside director shall automatically be granted
a nonqualified stock option to purchase 1,500 shares. The Directors' Plan
provides for the granting of options at an option price of not less than the
fair market value on the date of grant and shall terminate on December 31, 2004
or at such earlier time as the Board may determine.

Stock option balances and transactions under the 1988 Plan, the Executive Plan,
and the Directors' Plan at and during the years ended September 30, 1995, 1994,
and 1993 are summarized as follows:

The Company's 401(k) savings plan covers all employees with one or more years
of service. The Company matches employee contributions up to 2.5% of eligible
earnings. The Company's contributions for 1995, 1994 and 1993 totaled $644,000,
$563,000 and $498,000, respectively.

The Company is not obligated to provide any postretirement medical or life
insurance benefits to employees.

NOTE 9 - BUSINESS SEGMENT AND MAJOR CUSTOMERS:

The Company and its subsidiaries operate in one business segment, the
production and sale of electronic products including the designing,
manufacturing, programming and testing of computerized electronic assemblies.

Approximate sales to various divisions of a major customer were 25.6%, 39.4%
and 36.6% of consolidated net sales for the years ended September 30, 1995,
1994 and 1993, respectively. Additionally, sales to various divisions of
another major customer approximated 17.3%, 15.6% and 18.7% of consolidated net
sales for the years ended September 30, 1995, 1994 and 1993, respectively.

NOTE 10 - TRANSACTIONS WITH RELATED PARTIES:

During 1993 and 1992, a wholly-owned subsidiary of the Company, Plexus General
Partner Corp., made capital contributions totaling $700,000 to the Plexus Home
Automation Limited Partnership ("PHALP"). Several of the limited partners of
PHALP are officers, directors and/or shareholders of the Company and/or other
Company subsidiaries. The Company recorded losses of $413,000 in the years 1993
through 1995 which reduced the carrying value of this investment.  PHALP became
inactive during the latter half of 1995 and as a result the Company wrote off
its remaining investment in the partnership of $57,000 and certain other
related assets of $180,000. The Company billed PHALP $41,000, $65,000 and
$693,000, during the years 1995, 1994 and 1993, respectively, for certain
services rendered by the Company.

During 1994, promissory notes aggregating $5,000,000, which were payable to
certain shareholders of the Company who are also limited partners in PHALP,
were paid in full with the proceeds from the issuance of the Series A Preferred
Stock. The preferred shares were issued to and are held by the former holders
of the promissory notes described above.

(*) Income per common share is computed independently for each quarter. The
annual per share amount may not equal the sum of the quarterly amounts due to
rounding. The amounts shown for 1994 represent primary and fully diluted
earnings per common share.


The Company recognized adjustments in the fourth quarter of 1995 and 1994
related principally to the adjustment of perpetual inventory records to actual
balances which decreased and increased quarterly earnings per share by $(.02)
and $0.05, respectively.

REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF PLEXUS CORP.

We have audited the accompanying consolidated balance sheets of Plexus Corp.
and Subsidiaries as of September 30, 1995 and 1994, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended September 30, 1995. 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 Plexus Corp. and
Subsidiaries as of September 30, 1995 and 1994, and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended September 30, 1995, in conformity with generally accepted accounting
principles.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Plan Administrator
 and Employee-Participants

We have audited the financial statements of the Plexus Corp. Employee Stock 
Savings Plan as listed on the accompanying index. These financial statements 
are the responsibility of the Plan Administrator. 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 required 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 net assets available for benefits of the Plan as of 
September 30, 1995 and 1994, and the changes in net assets available for plan 
benefits for the years then ended in conformity with generally accepted 
accounting principles.

Our audit was conducted for the purpose of forming an opinion on the basic 
financial statements taken as a whole. The supplemental schedules as listed on 
the accompanying index are presented for the purpose of additional analysis and 
are not a required part of the basic financial statements but are supplementary 
information required by the Department of Labor's Rules and Regulations for 
Reporting and Disclosure under the Employee Retirement Income Security Act of 
1974. The supplemental schedules have been subjected to the auditing procedures 
applied in the audit of the basic financial statements and, in our opinion, are 
fairly stated in all material respects, in relation to the basic financial 
statements taken as a whole.

PLEXUS CORP. EMPLOYEE STOCK SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS

1.  DESCRIPTION OF PLAN:

    The following description of the Plexus Corp. Employee Stock Savings Plan
    (the "Plan") provides only general information. Participants should refer to
    the Plan agreement for a more complete description of the Plan's provisions.

    A.  GENERAL:  The Plan, effective January 1, 1989, is a contributory defined
        contribution plan covering all employees of Plexus Corp. (the "Company")
        who have completed one year of service. The Plan is subject to the
        provisions of the Employee Retirement Income Security Act of 1974
        ("ERISA").

    B.  CONTRIBUTIONS:  Employee pre-tax contributions are based on voluntary
        written elections by the participants directing the Company to defer a
        stated amount from the participants' compensation. Participants may
        elect to defer a stated amount from the participants' of 1% up to 2.5%
        of their annual compensation as a basic contribution. In addition,
        participants may elect to defer up to additional 7.5% of their annual
        compensation as a supplemental contribution. The Company will make a
        matchng contribution on behalf of a participant equal to 100% of the
        basic contribution. All Company matching contributions are allocated to
        the Employer Securities Fund. There is no Company matching of the
        supplemental contribution. Contributions are limited by Section 401(k)
        of the Internal Revenue Code.

        The Plan allows participants to elect the investment vehicle for their
        contributions from among several investment options. Investment options
        consist of an Employer Securities Fund, a Balanced Fund, a Principal
        Fund, and a Diversified Equity Fund, or any combination of the four,
        maintained by the Associated Bank, N.A. (the "Trustee"). The Employer
        Securities Fund invests primarily in the common stock of the Company.
        The Balanced Fund invests primarily in a combination of equity, fixed
        income and money market securities (or similar investments), with the
        objective of producing consistent long-term growth. The Principal Fund
        invests primarily in guaranteed investment contracts, commercial paper,
        and other money market securities (or similar investments), with the
        objective of providing safety of principal while generating interset
        income. The Diversified Equity Fund invests in a diversified portfolio
        of common stocks with the goal of producing a high total return from a
        combination of stock price appreciation and cash dividends. For all four
        funds, there is no guarantee as to future returns nor is there a
        guarantee against loss of principal.

    C.  PARTICIPANT ACCOUNTS AND ALLOCATIONS:  Each participant's account is
        credited with the participant's contribution and allocations of Company
        contributions and Fund investment earnings. Allocations are based on
        participant account balances in relation to total Fund account balances,
        as defined by the Plan document. Participants in the Employer Securities
        Fund are allocated an undivided interest in the shares held by the Fund.
        At September 30, 1995 and 1994, the Employer Securities Fund held
        462,679 and 383,596 shares of Plexus Corp. common stock valued at
        $16.625 and $10.625 per share, respectively.

1.  DESCRIPTION OF PLAN, CONTINUED:

    D.  VESTING AND DISTRIBUTIONS:  Participants immediately vest in all
        contributions made to the Plan. Participant accounts are distributable
        in the form of a lump sum payment or annual installments (period not to
        exceed the period permitted under Section 401(1)(9) of the code) of cash
        or in whole shares of the Company securities as elected by the
        participant upon a participant's retirement, termination of employment,
        death, disability, financial hardship or attainment of age 59-1/2.
        Participants with account balances exceeding $3,500 as of the
        distribution determination date may elect to defer distribution until
        the participant's attainment of age 65 or termination of employment,
        whichever is later. In any event, participant distributions may not be
        deferred past April 1 of the calendar year following the year in which
        the participant attains age 70-1/2. Forfeitures of unclaimed
        distributions are used to reduce Company matching contributions.

    E.  PLAN TERMINATION:  Although it has not expressed any intent to do so,
        the Company has the right under the Plan to discontinue its
        contributions at any time and to terminate the Plan subject to the
        provisions set forth in ERISA. In the event of Plan termination, the
        accounts of the participants shall be nonforfeitable.

    F.  CHANGES TO THE PLAN:  Commencing January 1, 1996, Plexus Corp.'s
        Employee Stock Savings Plan will be modified. Associated mutual funds
        will be eliminated and replaced with eight mutual funds maintained by
        Riggs National Bank of Washington, D.C., the new trustee. The new
        investment advisor will be Robert W. Baird & Co. of Milwaukee, WI. In
        addition, participants will be allowed to invest up to 15% of their
        income in increments of 5%. Participants will be allowed to transfer
        among all of the funds on a daily basis (except Plexus Common Stock
        which is limited to one transfer per month), and will have access to
        their accounts on a daily basis via an interactive telephone system. The
        Company match will remain at 2.5% and remain in Plexus Common Stock.

2.  SUMMARY OF ACCOUNTING POLICIES:

    The significant accounting policies followed by the Plan in presenting 
    these financial statements are as follows:

     A.  INVESTMENTS:  Investments in the Employer Securities Fund consist
         primarily of investments in Company securities which are traded on the
         NASDAQ exchange and are valued at the last reported sales price on the
         last business day preceding the valuation date. Investments in the
         Balanced Fund, the Principal Fund, and the Diversified Equity Fund
         consist of units of participation, representing an interest in the
         underlying assets of certain commingled trust funds maintained by the
         Trustee, rather than ownership of specific assets. The value of a unit
         or participation is the total value of the respective fund divided by
         the number of units outstanding. The trusts' investments in securities
         traded on a national securities exchange are valued at the last
         reported sales price. Obligations of U.S. Government securities and
         securities traded on the over-the-counter market are valued at the mean
         between hid and asked prices. Other securities are stated at fair
         market value as determined from independent sources. Money market funds
         held by the trusts are valued at cost which approximates fair value.
         The market value of all non-money market funds is determined on a
         monthly basis. Money market funds are valued on a daily basis.

         Purchases and sales of securities are reflected on a trade-date basis.
         The Plan presents in the statement of changes in net assets the net
         appreciation (depreciation) in the fair value of its investments which 
         consists of the realized gains or losses and the unrealized
         appreciation (depreciation) on those investments.

     B.  INTEREST INCOME:  Interest income from securities is recorded as earned
         on an accrual basis.

     C.  ADMINISTRATIVE EXPENSES:  Expenses incurred in the administration of
         the Plan are paid by the Company and are not reflected within these
         financial statements.

4.  TAX STATUS:

    The United States Treasury Department advised the Plan on May 15, 1990 that
    the Plan constitutes a qualified trust under Section 401(a) of the  
    Internal Revenue Code and is therefore exempt from Federal income taxes
    under  provisions of Section 501(a).


    The Plan has been amended since receiving the determination letter. 
    However, the plan administrator believes that the Plan is currently
    designed and being operated in compliance with the applicable requirements
    of the Internal Revenue Code. Therefore, no provision for income taxes has
    been included in the financial statements.

    Participants will not be subject to income tax on contributions made on     
    their behalf by the Company nor on the plan earnings credited to their
    account until such time as they withdraw all or any part of their
    accumulated balance.
