SECTION 2        AMOUNTS AND TERMS OF REVOLVING CREDIT COMMITMENTS


                 2.1      Revolving Credit Commitments.  Subject to the terms
and conditions hereof, and so long as no Default exists, each Bank agrees to
make revolving credit loans (the "Loans") to the Company during the Commitment
Period up to the amount of its Commitment; provided that the aggregate
principal amount of Loans at any one time outstanding shall not exceed the
lesser of (i) the Maximum Amount of Credit or (ii) the Borrowing Base.  The
respective obligations of the Banks under this Agreement to make the Loans
contemplated hereby are several and are not joint or joint and several.  The
failure of one of the Banks to make any Loan shall not relieve the other Banks
of their obligations to lend hereunder, and in no event shall such other Banks
or the Agent be liable in any way whatsoever for such failure to make any Loan
hereunder.  No Bank shall be obligated in any event to lend in excess of its
Commitment.  During the Commitment Period, the Company may borrow





                                       7
   12

and repay the Loans in whole or in part, and reborrow, all in accordance with
the terms and conditions hereof.

hereto shall be evidenced by a promissory note of the Company, in the form of
Exhibit A hereto with appropriate insertions (individually, a "Note" and
collectively, the "Notes"), payable to the order of that Bank in the amount of
that Bank's Commitment. Each Note shall (a) be dated the date hereof, (b) be
stated to mature on the Termination Date, (c) bear interest on the unpaid
principal amount thereof from time to time outstanding, and (d) be in the
principal amount of each Bank's Commitment, notwithstanding that the Company
shall be obligated to pay only the unpaid principal amount thereof from time to
time outstanding together with accrued interest thereon.

                 2.3      Interest Calculation.

                          (a)     Interest.  The principal amount of the
         indebtedness from time to time evidenced by the Notes shall
         accrue and bear interest at a rate per annum which shall at all times
         equal the Applicable Rate.  On the last day of each LIBOR Interest
         Period or on any earlier termination of any LIBOR Pricing Option, the
         Company will pay the accrued and unpaid interest on the indebtedness
         evidenced by the Notes which was subject to the LIBOR Pricing Option
         which expired or terminated on such date; provided, however, that if
         any LIBOR  Interest Period is longer than one month, the Company will
         also pay on the last day of each month in such LIBOR Interest Period
         the amount of accrued and unpaid interest on the portion of the
         principal amount of the indebtedness evidenced by the Notes subject to
         the LIBOR Pricing Option having such LIBOR Interest Period.  On any
         stated or accelerated maturity of the indebtedness evidenced by the
         Notes all accrued and unpaid interest on such indebtedness shall be
         forthwith due and payable, including without limitation any accrued and
         unpaid interest on such indebtedness which is subject to a LIBOR
         Pricing Option.  In addition, the Company will, on demand, pay interest
         on any overdue installments of principal and pay interest during the
         continuance of any Event of Default both at a rate per annum which is
         at all times equal to the sum of (a) the Applicable Rate (or, if more
         than one Applicable Rate is then in effect, the weighted average of the
         Applicable Rates then in effect) plus (b) 2% per annum.

                          (b)     Applicable Rate.  The term "Applicable Rate"
         shall mean the sum of (i) for any portion of the Indebtedness
         evidenced by the Notes which is at the time subject to an effective
         LIBOR Pricing Option, the Libor Rate, and otherwise the Prime Rate,
         plus (ii) in each case, the applicable spread set forth in the table

         The Applicable Spread shall be effective on the first day of each
         month based upon the monthly financial statements delivered in the
         immediately preceding month; provided that if no such financial
         statements have been delivered in the preceding month, the Applicable
         Spread shall be the highest applicable rate set forth in the table
         above.

                          (c)     The LIBOR Pricing Options.  The following

                          Screen LIBO Page (or such other page on which the
                          appropriate information may be displayed), on the

                          the rates at which deposits in U.S. dollars are
                          offered by four major banks in the London interbank
                          market, as selected by the Agent ("Reference Banks"),

                          If fewer than two quotations are provided as
                          requested, the applicable rate will be the mean of the
                          rates quoted by major banks in New York City, selected
                          by the Agent, at approximately 11 a.m., New York City
                          time, on the Calculation Date for loans in U.S.
                          dollars to leading European banks for the applicable
                          LIBOR Interest Period and in an amount equal to the
                          principal amount of the Loans subject to the
                          applicable LIBOR Pricing Option.

                                  (B)      The term "LIBOR Interest Period"
                          shall mean any period, selected as provided below in
                          this Section 2.3(c), of one, two, three, four, six,
                          or twelve months, each commencing on any Business
                          Day.  Such LIBOR Interest Period shall end on the day
                          in the succeeding calendar month which corresponds
                          numerically to the beginning day of such LIBOR
                          Interest Period, provided, however, that if there is
                          no such numerically corresponding day in such
                          succeeding month, such LIBOR Interest Period shall
                          end on the last Business Day of such succeeding
                          month.  If any LIBOR Interest Period so selected
                          would otherwise end on a date which is not a Business
                          Day, such LIBOR Interest Period shall instead end on
                          the immediately succeeding Business Day, provided,
                          however, that if said next succeeding Business Day
                          falls in a new month, such LIBOR Interest Period
                          shall end on the immediately preceding Business Day.

                                  (C)      The term "LIBOR Pricing Options"
                          shall mean the options granted pursuant to this
                          Section 2.3(c) to have the interest on all or any
                          portion of the principal amount of indebtedness
                          evidenced by the Notes computed with reference to a
                          LIBOR Rate.

                                  (D)      The term "LIBOR Rate" for any LIBOR
                          Interest Period shall mean a rate per annum equal to
                          the sum of (i) the quotient of (A) the Basic LIBOR
                          Rate applicable to that LIBOR Interest Period divided
                          by (B) one minus the LIBOR Reserve Requirement
                          (expressed as a decimal) applicable to that LIBOR
                          Interest Period, plus (ii) in the case of a LIBOR
                          Interest Period which is greater than six months,
                          one-quarter percent (1/4%).  The LIBOR Rate shall be
                          rounded, if necessary, to the next higher 1/16 of 1%.

                                  (E)  The term "LIBOR Reserve Requirement"
                          shall mean, with respect to each LIBOR Interest
                          Period, the stated maximum rate of all reserve
                          requirements (including all basic, supplemental,
                          marginal and other reserves and taking into account
                          any transitional adjustments or other scheduled
                          changes in reserve requirements during such LIBOR
                          Interest Period) that is specified on the first day
                          of such LIBOR Interest Period by the Board of
                          Governors of the Federal Reserve System for
                          determining the maximum reserve requirement with
                          respect to eurocurrency funding (currently referred
                          to as "Eurocurrency liabilities" in Regulation D of
                          such Board of Governors) applicable to the class of
                          banks of which the Banks are members.

                                  (F)  The term "Regulatory Change" means any
                          change enacted or issued after the date of this
                          Agreement of any (or the adoption after the date of
                          this Agreement of any new) federal or state law,
                          regulation, interpretation, direction, policy or
                          guideline, or any court decision, which affects (or,
                          in the case of a court decision would, if the
                          decision were applicable to any Bank, affect) the
                          treatment of any Loans of such Bank.

                          (2)     Election of LIBOR Pricing Options.
                 Notwithstanding any of the provisions of Section 2.5 of the
                 Loan Agreement, and subject to all the terms and conditions
                 hereof, the Company may, by notice to the Agent received not
                 later than 10:30 a.m. (Milwaukee time) on the date three
                 Business Days prior to the commencement of the LIBOR Interest
                 Period selected in such notice, elect to have all or such
                 portion of the principal amount of indebtedness then evidenced
                 (or to be evidenced at the commencement of such LIBOR Interest
                 Period) by the Notes as the Company may specify in such notice
                 (in the minimum amount of $1,750,000) accrue and bear daily
                 interest during the LIBOR Interest Period so selected at a per
                 annum rate equal to the Applicable Rate computed on the basis
                 of the LIBOR Rate for such LIBOR Interest Period; provided,
                 however, that no such election shall become effective if,
                 prior to the commencement of such LIBOR Interest Period, the
                 Agent determines (which determination shall be binding and
                 conclusive on all parties) that (i) by reason of circumstances
                 affecting the London interbank market adequate and reasonable
                 means do not exist for ascertaining the applicable LIBOR Rate;
                 (ii) the LIBOR Rate does not accurately reflect the cost to
                 the Banks of making or maintaining a loan subject to such
                 LIBOR Pricing Option; or (iii) any Default or Event of Default
                 has occurred and is continuing.  Each notice of election of a
                 LIBOR Pricing Option shall be irrevocable.  The Agent shall
                 inform each Bank of each election of a LIBOR Pricing Option by
                 not later than 1:30





                                       11
   16

         p.m. Milwaukee time on the date notice of such election is received by
         the Agent.

         (d)      Special Provisions.

             (1)     Increased Costs.  If any Regulatory Change,

                                  (A)      shall subject any Bank to any tax,
                          duty or other charge with respect to any of its
                          Loans, or shall change the basis of taxation of
                          payments to any Bank of the principal of or interest
                          on its Loans, or any other amounts due under this
                          Agreement in respect of its Loans, or its obligation
                          to make Loans (except for changes in the rate of tax
                          on the overall net income of such Bank);

                                  (B)  shall impose, modify or make applicable
                          any reserve (including, without limitation, any
                          reserve imposed by the Board of Governors of the
                          Federal Reserve System, but excluding any reserve
                          included in the determination of interest rates on
                          Loans), special deposit or similar requirement
                          against assets of, deposits with or for the account
                          of, or credit extended by, any Bank; or

                                  (C)  shall impose on any Bank any other
                          condition affecting its Loans;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D or any other analogous law, rule or regulation, to impose
a cost on) such Bank of making or maintaining any Loans or to reduce the amount
of any sum received or receivable by such Bank under the Agreement and any
document or instrument related thereto, then after 15 days' notice from such
Bank (which notice shall be sent to the Agent and the Company and shall be
accompanied by a statement setting forth the basis of such notice), the Company
shall pay directly to such Bank, on demand, such additional amount or amounts
as will compensate such Bank for such increased cost or such reduction incurred
on or after the date of the giving of such notice to the Agent and the Company.

                          (2)     Changes in Law Rendering Certain Loans
                 Unlawful.  In the event that any Regulatory Change should make
                 it (or, in the good faith judgment of a Bank, should raise
                 substantial questions as to whether it is) unlawful for a Bank
                 to make, maintain or fund a Loan subject to a LIBOR Rate, then
                 (i) such Bank shall promptly notify each of the other parties
                 hereto, (ii) the obligation of all Banks to make such Loan
                 shall, upon the effectiveness of such event, be suspended for
                 the duration of such unlawfulness, and (iii) upon such notice,
                 any outstanding Loan subject to a LIBOR Rate shall
                 automatically be





                                       12
   17

                 subject to the Applicable Rate set forth in Section 2.3(b)(2).

                          (3)     Funding Losses.  The Company hereby agrees
                 that upon demand by any Bank (which demand shall be sent to
                 the Agent and the Company and shall be accompanied by a
                 statement setting forth the basis for the calculations of the
                 amount being claimed) the Company will indemnify such Bank
                 against any net loss or expense which such Bank may sustain or
                 incur (including, without limitation, any net loss or expense
                 incurred by reason of the liquidation or reemployment of
                 deposits or other funds acquired by such Bank to fund or
                 maintain Loans subject to a LIBOR Rate), as reasonably
                 determined by such Bank, as a result of (i) any payment,
                 prepayment or conversion of any Loan subject to a LIBOR Rate
                 of such Bank on a date other than the last day of a LIBOR
                 Interest Period for such Loan whether or not required by any
                 other provision of this Agreement, or (ii) any failure of the
                 Company to borrow any loans on a date specified therefor in a
                 notice of borrowing pursuant to this Agreement.

                          (4)     Discretion of Banks as to Manner of Funding.
                 Notwithstanding any provision of this Agreement to the
                 contrary, each Bank shall be entitled to fund and maintain its
                 funding of all or any part of its Loans in any manner it sees
                 fit.

                          (5)     Capital Adequacy.  If any Regulatory Change
                 affects the treatment of any Loan of a Bank as an asset or
                 other item included for the purpose of calculating the
                 appropriate amount of capital to be maintained by such Bank or
                 any corporation controlling such Bank and has the effect of
                 reducing the rate of return on such Bank's or such
                 corporation's capital as a consequence of the Loans or
                 Commitments of such Bank hereunder to a level below that which
                 such Bank or such corporation could have achieved but for such
                 Regulatory Change (taking into account such Bank's or such
                 corporation's policies with respect to capital adequacy) by an
                 amount deemed in good faith by such Bank to be material, then
                 after 15 days' notice from such Bank to the Company and the
                 Agent of such Regulatory Change, the Company shall pay to such
                 Bank, on demand, such additional amount or amounts as will
                 compensate such Bank or such corporation, as the case may be,
                 for such reduction incurred on or after the date of the giving
                 of such notice to the Agent and the Company.  Such Bank shall
                 submit, to the Agent and the Company, a statement as to the
                 amount of such compensation, prepared in good faith and in
                 reasonable detail.

                          (6)     Conclusiveness of Statements; Survival of
                 Provisions.  Determinations and statements of any Bank
                 pursuant to sections 2.3(d)(1), (2), (3) and (5) shall be





                                       13
   18

                 conclusive absent manifest error.  The provisions of
                 section 2.3(d)(1), (3) and (5) shall survive the obligation of
                 the Banks to extend credit under this Agreement.

                 2.4      Commitment Fee.  The Company will pay, with respect
to each Note, a commitment fee of one-quarter of one percent (1/4%), on a per
annum basis, as to the unused portion of the Commitment represented by such
Note during the period from the date of this Agreement to the date on which the
Commitment is terminated and the entire amount of principal of and interest due
on such Note is paid in full.  The amount of such fee shall be calculated based
upon the number of actual days this Agreement is in effect and a year of 360
days.  The fee shall be payable quarterly in arrears on the later of (i) the
twentieth day of the first month in each calendar quarter or (ii) five days
after the Company's receipt of the invoice therefor.

                 2.5      Procedure for Revolving Credit Loans.  The Company
may obtain Loans by making a request therefor to the Agent, orally or in
writing by delivering to the Agent a Loan Request in the form of Exhibit B
hereto.  Such request shall specify a Business Day during the Commitment Period
on which such Loans are to be made (the "Borrowing Date"), shall be received by
the Agent by 12:00 noon Milwaukee time on the Borrowing Date, and shall specify
the amount of the Loans requested; provided, however, that within three days
after any oral request for a Loan, the Agent shall receive from the Company a
Loan Request in the form of Exhibit B confirming the Company's request, and
each Bank's obligation to make further Loans hereunder shall be suspended until
such Loan Request has been received by the Agent.  Each Loan shall be in the
minimum principal amount of One Hundred Thousand Dollars ($100,000) or a
multiple of $50,000 in excess thereof (except as otherwise provided in section
2.3(c)(2) with respect to Loans subject to Libor Pricing Options), and shall be
made pro rata from the Banks in accordance with their respective Percentage
Interests. The Agent shall inform each Bank of such request by not later than
1:30 p.m. Milwaukee time on the Borrowing Date.  Not later than 3:30 p.m.
Milwaukee time on the Borrowing Date, each Bank shall make available to the
Agent at its principal office in Milwaukee, Wisconsin, in immediately available
funds, the amount of such Bank's Percentage Interest in such Loan.  Upon
receipt by the Agent of such amount from a Bank, and fulfillment of the
conditions specified in Section 4.2 hereof, the Agent shall make such amount
available to the Company by promptly depositing such amount in the general
deposit account of the Company maintained with the Agent.

                 2.6      Application of Payments.  All payments of principal
and interest hereunder and under the Notes and all payments of fees hereunder
shall be made to the Agent not later than 12:00 noon on the date of required
payment in immediately available funds for the ratable account of the Banks.
The Agent shall promptly (but not later than 3:00 p.m. on the date of payment)
distribute to the Banks, pro rata in accordance with their respective
Percentage Interests, the amount of principal and interest and fees received





                                       14
   19

by the Agent.  Any payment to the Agent for the account of a Bank hereunder
shall constitute a payment by the Company to such Bank of the amounts so paid
to the Agent, and any Notes or portions thereof so paid shall not be considered
outstanding for any purpose after the date of such payment to the Agent.  All
payments or prepayments of principal and interest and fees shall be made pro
rata in accordance with the respective Percentage Interests of the Banks in all
Loans then outstanding. In the event any Bank shall receive from the Company or
any other source (other than the sale of a participation to another commercial
lender in the ordinary course of business) any payment of, on account of, or
for an obligation of the Company hereunder or under the Notes (whether pursuant
to the exercise of any right of set-off, banker's lien, realization upon any
security held for or appropriated to such obligation, counterclaim or
otherwise) other than as provided above, then such Bank shall immediately
purchase, without recourse and for cash, an interest in the obligations of the
same nature held by the other Banks so that each Bank shall thereafter have a
Percentage Interest in all obligations of the Company hereunder equal to the
Percentage Interest of such Bank set forth in Section 1.8 of this Agreement;
provided, if any payment so received shall be recovered in whole or in part
from such purchasing Bank, the purchase shall be rescinded and the purchase
price restored to the extent of such recovery, but without interest.  The
Company specifically acknowledges and consents to the preceding sentence.

                 2.7      Borrowing Base Certificate.  On or before the 15th
day of each calendar month, the Company shall deliver to each of the Banks a
Borrowing Base Certificate in the form attached hereto as Exhibit C as of the
last day of the preceding month.

                 2.8      Prepayments.

                          (a)     Optional Prepayments.  The Company may, at
         its option, at any time and from time to time, prepay the Loans
         hereunder, in whole or in part, without premium or penalty (but
         subject to section 2.3(d)(3) in cases of Loans bearing interest at a
         LIBOR Rate), together with accrued interest to the date of such
         prepayment on the amount so prepaid.  Partial prepayments shall be in
         the principal amount of One Hundred Thousand Dollars ($100,000) or a
         multiple of $50,000 in excess thereof.

                          (b)     Mandatory Prepayment.  At any time that the
         aggregate principal amount of Loans outstanding hereunder exceeds the
         Borrowing Base then in effect, the Company shall immediately prepay
         the amount by which such Loans exceed the Borrowing Base, together
         with interest accrued on the amount of the prepayment.

                 2.9      Security.  Payment of all principal and interest

SECTION 3        REPRESENTATIONS AND WARRANTIES


                 In order to induce the Banks to make the Loans as herein
provided, the Company hereby represents and warrants to the Banks as follows:

                 3.1      Organization; Qualification and Subsidiaries. The
Company is validly organized and existing and in good standing under the laws
of the State of Wisconsin and has the corporate power and all necessary
licenses, permits and franchises to borrow hereunder and to grant the lien and
security interest provided for in the Security Agreement and to own its assets
and conduct its business as presently conducted.  The Company is duly licensed
or qualified to do business in all jurisdictions where failure to qualify would
have a material adverse effect upon the Company, and the Company has no
material liabilities as a result of any failure to qualify to do business as a
foreign corporation in any jurisdiction.  All of the issued and outstanding
capital stock of the Company has been validly issued and is fully paid and
non-assessable, except as provided in Section 180.0622(2)(b) Wis. Stats., and
is owned by Plexus Corp. free and clear of all pledges, liens, security
interests and other charges or encumbrances. The Company has no Subsidiaries.

                 3.2      Financial Statements. The audited consolidated
balance sheet of Plexus Corp. as of September 30, 1995, and the related audited
consolidated statements of income, shareholders' equity and cash flows for the
period ended on that date, are accurate and complete and were prepared in
accordance with GAAP, and present fairly the financial condition of Plexus
Corp. as of such date and the results of its operations for the period then





                                       16
   21

ended.  There has been no material adverse change in the business, properties
or condition, financial or otherwise, of the Company since the date of such
financial statements.

                 3.3      Authorization; Enforceability.  The Loans
contemplated by this Agreement have been duly authorized by all necessary
corporate action.  The making, execution, delivery and performance of this
Agreement, the Notes, and the Security Agreement by the Company have each been
duly authorized by all necessary corporate action.  This Agreement and the
Security Agreement are, and the Notes, when executed, delivered and issued by
the Company will be, the valid and binding obligations of the Company,
enforceable against the Company in accordance with their respective terms,
except as limited by bankruptcy, insolvency or similar laws generally affecting
the enforcement of creditors rights.

                 3.4      Absence of Conflicting Obligations.  The making,
execution and performance of this Agreement, the Notes, and the Security
Agreement and compliance with their respective terms do not violate or
constitute a default under any provision of law or the Articles of
Incorporation or Bylaws of the Company or any material agreement or instrument
to which the Company is a party or by which it is bound, or require the consent
or approval of, or filing or registration with, any Government Authority.

                 3.5      Taxes.  The Company has filed all federal, state,
foreign and local tax returns which were required to be filed, except those
returns for which the due date has been validly extended.  The Company has paid
or made provisions for the payment of all taxes owed, and no tax deficiencies
have been proposed or assessed against the Company.  There are no pending or,
to the knowledge of the Company, threatened tax controversies or disputes as of
the date hereof.  The Company's federal income tax returns for all tax years
through the year ended September 30, 1991 are no longer subject to audit, and
all taxes shown by such returns have been paid.

                 3.6      Absence of Litigation.  The Company is not a party
to, nor so far as is known to the Company is there any threat of, any
litigation or administrative proceeding which in either case (i) relates to the
execution, delivery or performance of this Agreement, the Notes, the Security
Agreement or the Guaranties, (ii) would, if adversely determined, cause any
material adverse change in the assets and properties of, or any material
impairment of the right to carry on the business as now or proposed to be
conducted by, or cause any material adverse effect on the financial condition
of, the Company as a whole, or (iii) asserts or alleges that the Company is in
violation of, or has any liability under, Environmental Laws except as
disclosed on Schedule 3.6.  To the best of the Company's knowledge after
diligent inquiry, there are no presently existing facts or circumstances likely
to give rise to any such litigation or administrative proceeding.

                 3.7      Accuracy of Information.  All information,
certificates or statements given by the Company in, or pursuant to, this
Agreement were accurate, true and complete in all material respects when given,
continue to be accurate, true and complete as of the date hereof, and do not
contain any untrue statement or omission of a material fact necessary to make
the statements therein not misleading.  There is no fact known to the Company
which materially and adversely affects, or which in the future may (so far as
the Company can reasonably foresee) materially and adversely affect, the
business, properties, operations or condition, financial or otherwise, of the
Company which has not been set forth in this Agreement, the Security Agreement,
or other documents, certificates or statements furnished to the Banks or the
Agent by or on behalf of the Company in connection with the transactions

                 3.9      Federal Reserve Regulations.  The Company will not,
directly or indirectly, use any Loan to purchase or carry any "margin stock"
within the meaning of Regulation U of the Board of Governors of the Federal
Reserve System (12 C.F.R. 221, as amended), or otherwise take or permit any
action which would involve a violation of any regulation of the Board of
Governors of the Federal Reserve System.

                 3.10     ERISA.  The Company and all Employee Plans are in

the regulations and published interpretations thereunder and (i) no "prohibited
transaction" as defined in Section 406 of ERISA or Section 4975 of the Code has

4043 of ERISA, nor has the Company incurred any material liability to the PBGC

"accumulated funding deficiency," as defined in Section 302(a)(2) of ERISA
(whether or not waived) has occurred. There are no Unfunded Liabilities of any
Employee Plans.

                 3.11     Security Agreement.  Upon the execution of the
Security Agreement and the filing of the financing statements thereunder in the
manner prescribed by the UCC, the Banks shall have a legal, valid and perfected
first priority security interest in the property of the Company and TGI
described in the Security Agreement, valid against all creditors of the Company
and TGI, and against all purchasers from the Company or TGI (except to the
extent provided in the UCC), and the property subject to the





                                       18
   23

Security Agreement shall be free and clear of all other Liens whatsoever,
except Permitted Liens.

                 3.12     Places of Business.  The principal place of business
and chief executive office of the Company is located at 2121 Harrison Street,
Neenah, Wisconsin, and the books and records of the Company and all records of
account are located and hereafter shall continue to be located at such
principal place of business and chief executive office or at the address
specified in Section 10.7 hereof, or at 701 Keeneland, Richmond, Kentucky.

                 3.13     Other Names.  The business conducted by the Company
has not been conducted under any corporate, trade or fictitious name other than
the name Electronic Assembly Corporation, and following the date hereof the
Company will not conduct its business under any trade or fictitious name unless
the Company shall have delivered prior written notice to the Agent of such name
change.

                 3.14     Investment Company Act.  The Company is not an
"investment company" or a company "controlled by an investment company" within
the meaning of the Investment Company Act of 1940, as amended.

                 3.15     Dividends and Redemptions.  The Company has not,
since September 30, 1995, paid or declared any dividend, or made any other
distribution on account of any shares of any class of its stock, or redeemed,
purchased or otherwise acquired, directly or indirectly, any shares of any
class of its stock, except as permitted hereby.  The Company is not a party to
any agreement which may require it to redeem, purchase or otherwise acquire any
shares of any class of its stock.

                 3.16     Contingent Liabilities.  The Company has no
guarantees or other contingent liabilities outstanding (including, without
limitation, liabilities by way of agreement, contingent or otherwise, to
purchase, to provide funds for payment, to supply funds to or otherwise invest
in the debtor or otherwise to assure the creditor against loss), except those
permitted by section 6.9 hereof.

                 3.17     Absence of Default.  No event has occurred which
either of itself or with the lapse of time or the giving of notice or both,
would give any creditor of the Company the right to accelerate the maturity of
any Indebtedness of the Company.  The Company is not in default under any other
lease, agreement or instrument, or any law, rule, regulation, order, writ,
injunction, decree, determination or award, non-compliance with which could
materially adversely affect its property, financial condition or business
operations.

                 3.18     Environmental Conditions.  To the Company's knowledge
after reasonable investigation, there are no conditions existing currently or
likely to exist during the term of this loan which would subject the Company to
damages, penalties, injunctive relief or cleanup costs under any Environmental
Laws or which





                                       19
   24

   29

therewith; or (c) incur or suffer to exist any material "accumulated funding
deficiency" (as defined in Section 302 of ERISA), whether or not waived,

         shall occur under any evidence of, or any indenture, lease, sublease,
         agreement or other instrument governing such obligations, and such

                 7.2      Remedies Upon Event of Default.

                          (a)     Upon the occurrence of an Event of Default
         specified in clauses (g) or (h) above, then, without presentment,
         notice, demand or action of any kind by the Agent or any Bank, all of
         which are hereby waived: (i) the Commitments and the obligation of
         each of the Banks to make any Loans hereunder shall automatically and
         immediately terminate; and (ii) the entire amount of unpaid principal
         of and accrued and unpaid interest on the Notes shall become
         automatically and immediately due and payable.

                          (b)     Upon the occurrence of any Event of Default
         specified in clause (a) above, the Agent may, and upon the request of
         any Bank shall, without presentment, notice, demand or action of any
         kind by the Agent or any Bank, all of which are hereby waived: (i)
         immediately terminate the Commitments and each Bank's obligation to
         make any Loans, and the same shall immediately be terminated; and (ii)
         declare the entire amount of the unpaid principal of and accrued and
         unpaid interest on the Notes immediately due and payable.

                          (c)     Upon the occurrence of any other Event of
         Default specified above, the Agent shall, upon the Requisite Consent

         the occurrence of an Event of Default, the Banks shall have all of the
         rights and remedies provided by the Security Agreement and the

         is intended to be exclusive of any other remedy and each and every
         such remedy shall be cumulative and shall be in addition to every
         other remedy given hereunder or now or hereafter existing at law or in
         equity or by statute or otherwise.  No failure or delay on the part of
         the Agent or the Banks in exercising any right or remedy hereunder
         shall operate as a waiver thereof nor shall any single or partial
         exercise of any right hereunder preclude other or further exercise
         thereof or the exercise of any other right or remedy.

                 7.3      Amendments.  Subject to the provisions of this
Section 7.3, the Requisite Consent of the Banks (or the Agent with





                                       27
   32

the Requisite Consent of the Banks) and the Company may enter into agreements
supplemental hereto for the purpose of adding or modifying any provisions to
this Agreement, the Notes, the Guaranties or the Security Agreement or changing
in any manner the rights of the Banks or the Company hereunder or thereunder or
waiving any Default hereunder; provided, however, that no such supplemental
agreement shall, without the consent of all of the Banks:

         principal amount thereof, or reduce the rate or change the time of
         payment of interest or fees thereon.

                          (b)     Amend the definition of Requisite Consent.

SECTION 8        RIGHTS AND DUTIES OF THE AGENT


                 8.1      Appointment and Duties of the Agent.  The parties
hereto agree that the Agent shall act, subject to the terms and conditions of
this Section 8, as the agent for the Banks, and to the extent set forth herein
each of the Banks hereby irrevocably appoints, authorizes, empowers and directs
the Agent to take such action on its behalf and to exercise such powers
hereunder and under the Security Agreement and the Guaranties as are
specifically delegated to the Agent herein and therein in connection with the
administration of and the enforcement of any rights or remedies with respect to
this Agreement, the Notes, the Security Agreement, and the Guaranties, together
with such powers as are reasonably incidental thereto.  The general
administration of the loans hereunder shall be with the Agent.  The duties of
the Agent shall be entirely ministerial; the Agent shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement, the Notes or any related
document, or to enforce such performance, or to





                                       28
   33

inspect the property (including the books and records) of the Company.  It is
expressly understood and agreed that the obligations of the Agent hereunder and
under the Security Agreement and the Guaranties are only those expressly set
forth in such agreements.  The Agent shall use reasonable diligence to examine
the face of each document received by it hereunder to determine whether such
document, on its face, appears to be what it purports to be. However, the Agent
shall not be under any duty to examine into or pass upon the validity or
genuineness of any documents received by it hereunder and the Agent shall be
entitled to assume that any of the same which appears regular on its face is
genuine and valid and what it purports to be.

                 8.2      Discretion and Liability of the Agent.  Subject to
Sections 8.3 and 8.5 hereof, the Agent shall be entitled to use its discretion
with respect to exercising or refraining from exercising any rights which may
be vested in it by, or with respect to, taking or refraining from taking any
action or actions which it may be able to take under or in respect of this
Agreement, the Security Agreement, and the Guaranties. Neither the Agent nor
any of its directors, officers or employees shall be liable for any action
taken or omitted by them hereunder or in connection herewith, except for its or
their own gross negligence or willful misconduct.  The Agent may execute any of
its duties under this Agreement by or through agents and attorneys-in-fact and
shall not be answerable for the default or misconduct of any such agent or
attorney-in-fact selected by it with reasonable care.  The Agent shall incur no
liability under, or in respect of this Agreement, the Security Agreement, or
the Guaranties by acting upon a notice, certificate, warranty or other paper or
instrument believed by it to be genuine or authentic or to be signed by the
proper party or parties, or with respect to anything which it may do or refrain
from doing in the reasonable exercise of its judgment, or which may seem to it
to be necessary or desirable in the premises. The Agent may at any time request
instructions from the Banks with respect to any action or approval that, by the
terms of this Agreement, the Agent is permitted or required to take or to
grant, and if such instructions are requested, the Agent shall be absolutely
entitled to refrain from taking any action or to withhold any approval and
shall not be under any liability whatsoever to any Person for refraining from
any action or withholding any approval under this Agreement until it shall have
received such instructions by the Requisite Consent of the Banks; Provided,
however, that the Agent shall not in any event be required to comply with any
instructions given it by the Requisite Consent of the Banks if the Agent
determines that such compliance would expose it to personal liability or is
contrary to law or to the terms of this Agreement, but the Banks shall in all
events indemnify the Agent from any action taken by it in accordance with the
instructions of the Requisite Consent of the Banks.  No Bank shall have any
right of action whatsoever against the Agent as a result of the Agent acting or
refraining from acting hereunder in accordance with instructions by the
Requisite Consent of the Banks.





                                       29
   34

                 8.3      Event of Default.  The Agent shall be entitled to
assume that no Default or Event of Default has occurred and is continuing,
unless the Agent has actual knowledge of such facts or has received notice from
a Bank in writing that such Bank considers that a Default or Event of Default
has occurred and is continuing, and which specifies the nature thereof.  In the
event that the Agent shall acquire actual knowledge of any Default or Event of
Default the Agent shall promptly notify (either orally or in writing) the Banks
and the Company of such Default or Event of Default and if, but only if,
directed by the Requisite Consent of the Banks, shall take such action and
assert such rights as are contemplated under this Agreement, the Security
Agreement, and the Guaranties.  The Agent shall be indemnified pro rata by the
Banks against any liability or expenses, including reasonable attorneys' fees,
incurred in connection with taking such action.

                 8.4      Consultation.  The Agent in good faith may consult
with legal counsel, accountants and other experts selected by it and shall be
entitled to fully rely upon any opinion of such counsel, accountants or experts
in connection with any action taken or suffered by the Agent in accordance with
such opinion.

                 8.5      Communications to and from the Agent.  Upon any
occasion requiring or permitting an approval, consent, waiver, election or
other action on the part of the Banks, unless action by the Agent alone is
expressly permitted hereunder, action shall be taken by the Agent for and on
behalf or for the benefit of all the Banks upon the direction of the Requisite
Consent of the Banks.  The Company may rely on any communication from the Agent
hereunder and need not inquire into the propriety of or authorization for such
communication.  Upon receipt by the Agent from the Company or any Bank of any
communication calling for an action on the part of the Banks, it will, in turn,
promptly inform the other Banks in writing of the nature of such communication.

                 8.6      Limitations of Agency.  Notwithstanding anything in
this Agreement or any of the other related documents, express or implied, it is
agreed by the parties hereto that the Agent will act hereunder and under the
Security Agreement and the Guaranties as Agent solely for the Banks and only to
the extent specifically set forth herein, and will, under no circumstances, be
considered to be an agent or fiduciary of any nature whatsoever in respect to
any other Person.  With respect to its Commitment and the Note issued to it,
Firstar Bank Milwaukee, N.A., in its individual capacity as a Bank, shall have,
and may exercise, the same rights and powers under this Agreement and the Note
payable to it as any other Bank has under this Agreement and the Notes, and the
terms "Bank" and "Banks", unless the context otherwise requires, shall include,
Firstar Bank Milwaukee, N.A. in its individual capacity as a Bank.  The Agent
may generally engage in any kind of banking or trust business with the Company
as if it were not the Agent.

                 8.7      No Representation or Warranty.  No Bank (including
the Agent) makes to any other Bank any representation or any warranty, express
or implied, or assumes any responsibility with





                                       30
   35

respect to the Loans or the execution, construction, legality, validity,
genuineness, sufficiency, collectability, value or enforceability of this
Agreement, the Notes, the Security Agreement, the Guaranties or any instrument
or agreement executed by the Company or any other person in connection
therewith.

                 8.8      Bank Credit Decision.  Each Bank acknowledges that it
has, independent of and without reliance upon the other Banks (or the Agent) or
any information provided by the other Banks (or the Agent) and based on the
financial statements of the Company and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  Each Bank also acknowledges that it will, independent of
and without reliance upon any other Bank (or the Agent) and based on such
documents and information as it shall deem appropriate at that time, continue
to make its own credit decisions in taking or not taking action under this
Agreement and any other documents related hereto including any commercial field
audits, it being understood and agreed that any commercial field audit
conducted by the Agent shall be for the sole benefit of Firstar Bank Milwaukee,
N.A.  A copy of such field audits shall be provided by the Agent to the other
Banks, but the Agent shall not be responsible for any errors or omissions in
such audits except in the case of willful misconduct by the employees or agents
of the Agent in preparing such audits.  Each Bank further agrees to inform the
other Banks of any information about the Company it believes to be materially
adverse to enable each Bank to continue to make its own credit decisions in
taking or not taking action under this Agreement and any other documents
related hereto.

                 8.9      Indemnity.  To the extent the Agent is not
indemnified by the Company pursuant to any of the provisions hereof, the Banks
shall severally indemnify, on a pro rata basis, the Agent against loss, cost,
liability, damage or expense arising from, or in connection with, its duties as
Agent hereunder and not caused by its gross negligence or willful misconduct.

                 8.10     Resignation.  The Agent may resign as such at any
time upon at least 30 days' prior notice to the Company and the Banks; provided
that such resignation shall not take effect until a successor agent has been
appointed.  In the event of such resignation, the Banks shall, as promptly as
practicable, appoint a successor agent, and if they fail to do so within 30
days after such notice, the Agent may appoint a successor agent.  If at any
time there is no Agent acting hereunder, the Company shall make all required
payments to, and otherwise deal directly with, the Banks and/or the holders of
the Notes, as the case may be.

                 8.11     Noteholders.  The Agent may treat the payee of any
Note as the holder thereof until written notice of transfer shall have been
filed with the Agent, signed by such payee and in form satisfactory to the
Agent.

   36

SECTION 9        INCREASED COSTS; CAPITAL ADEQUACY

                 9.1      Increased Costs.  If (i) the amendment of Regulation
D of the Board of Governors of the Federal Reserve System, or (ii) after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change therein, or any change in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Bank with
any request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency issued after the date hereof,

                          (a)     shall subject any Bank to any tax, duty or
         other charge with respect to the Loans, the Notes or such Bank's
         obligation to make or maintain any extension of credit hereunder, or
         shall change the basis of taxation of payments to such Bank of the
         principal of or interest on the Loans or any other amounts due under
         this Agreement in respect of any extension of credit hereunder or such
         Bank's obligation to make or maintain any extension of credit
         hereunder (except for changes in the rate of tax on the overall net
         income of such Bank imposed by the jurisdiction in which such Bank's
         principal executive office is located); or

                          (b)     shall impose, modify or deem applicable any
         reserve (including, without limitation, any reserve imposed by the
         Board of Governors of the Federal Reserve System), special deposit or
         similar requirement against assets of, deposits with or for the
         account of, or credit extended hereunder by, any Bank; or

                          (c)     shall impose on any Bank any other condition
         affecting any extension of credit hereunder, the Notes or such Bank's
         obligation to make or maintain any extension of credit hereunder;

and the result of any of the foregoing is to increase the cost to (or to impose
a cost on) of making or maintain any extension of credit hereunder or to reduce
the amount of any sum received or receivable by such Bank under this Agreement
or under the Notes with respect thereto, then upon demand by such Bank (which
demand shall be accompanied by a statement setting forth the basis of such
demand), the Company shall pay directly to such Bank such additional amount or
amounts as will compensate such Bank for such increased cost or reduction.

                 9.2      Capital Adequacy.  If either (i) the introduction of
or any change in or in the interpretation of any law or regulation, or (ii)
compliance by any Bank with any guideline or request from any central bank or
other governmental authority (whether or not having the force of law) affects
or would affect the amount of capital required or expected to be maintained by
such Bank or any corporation controlling such Bank and such Bank determines
that the amount of such capital is increased by or based upon the existence





                                       32
   37

of such Bank's commitment to make or maintain extensions of credit hereunder
and other commitments of this type, then, upon demand by such Bank, the Company
shall immediately pay to such Bank, from time to time as specified by such
Bank, additional amounts sufficient to compensate such Bank in light of such
circumstances, to the extent that such Bank reasonably determines such increase
in capital to be allocable to the existence of such Bank's commitment to make
or maintain extensions of credit hereunder.


SECTION 10       MISCELLANEOUS

                 10.1     Expenses and Attorneys' Fees; Indemnification.

delivered to such Bank by the Company or the Agent pursuant to this Agreement
or which has been delivered to such Bank by the Company or the Agent in

acknowledge and agree that the Company may from time to time enter into
agreements with one or more of the Banks (or their affiliates) relating to
interest rate swaps, caps, floors, collars, options or similar interest rate
hedging arrangements ("Interest Rate Hedges"), and that the Company may secure
its obligations thereunder by granting a lien on the "Collateral" (as defined
in the Security Agreement), provided that any lien on such "Collateral"
securing the Company's obligations to one or more of the Banks (or their
affiliates) under such Interest Rate Hedges shall at all times be junior and
subordinate to the lien created by the Security Agreement securing the
Company's obligations under this Agreement and the Notes.

         FOR VALUE RECEIVED, the undersigned, ELECTRONIC ASSEMBLY CORPORATION,
hereby promises to pay to the order of _______________ (the "Payee"), on July

as amended from time to time (the "Credit Agreement"), by and among the
undersigned, Firstar Bank Milwaukee, N.A., for itself and as Agent, and certain
other banks named therein, together with interest on the principal amount

of, the Credit Agreement.  All capitalized terms used herein shall have the
meanings assigned to them in the Credit Agreement.

in payment of, a promissory note previously issued by the undersigned to the

amended and restated in its entirety by the Credit Agreement referred to above.

presentment, protest and notice of dishonor, and agrees, in the event of
