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

     THIS AGREEMENT is made as of the 12th day of December 1995, by and among
MARQUETTE ELECTRONICS, INC., a Wisconsin corporation ("Borrower"), and M&I
MARSHALL & ILSLEY BANK, a Wisconsin banking corporation ("M&I"), NBD BANK, a
Michigan banking corporation (formerly known as NBD Bank, N.A.) ("NBD") and
WACHOVIA BANK OF GEORGIA, N.A., a national banking association ("Wachovia")
(collectively, the "Banks" and individually, a "Bank"). Unless otherwise
indicated herein, capitalized terms shall have the meanings set forth in Section
9 hereof.

                                  WITNESSETH:

     WHEREAS, Borrower is seeking to acquire all of the outstanding capital
stock of E for M Corporation, a Delaware corporation ("E for M"), pursuant to
the terms of a certain Agreement and Plan of Merger dated as of November 5, 1995
by and among Borrower, E for M and Marquette Sub Corp., a Delaware corporation
and wholly-owned subsidiary of Borrower ("Sub Corp") (the "Acquisition"); and

     WHEREAS, Borrower has requested that the Banks make the Term Loans (as
defined below) in the aggregate principal amount of $90,000,000, the proceeds of
which will be used to fund all or a portion of the purchase price for the
Acquisition; and

     WHEREAS, the Banks are willing to make the Term Loans to Borrower but only
on the terms and conditions hereinafter set forth and in reliance on the
representations and warranties of Borrower herein contained.

     NOW, THEREFORE, in consideration of the premises and mutual agreements
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged the parties hereto agree as
follows:

     1. Term Loans. M&I agrees to make a Term Loan to the Borrower in the amount
of $30,000,000 (the "M&I Term Loan"), NBD agrees to make a Term Loan to the
Borrower in the amount of $30,000,000 (the "NBD Term Loan") and Wachovia agrees
to make a Term Loan to the Borrower in the amount of $30,000,000 (the "Wachovia
Term Loan"), all on the terms and conditions hereinafter set forth in this
Agreement. The M&I Term Loan, the NBD Term Loan and the Wachovia Term Loan are
hereinafter collectively referred to as the Term Loans." Each of the Banks
agrees that their respective Term Loans may be made in two installments upon
request of the Borrower. The Banks shall not be required to make

 
any of the Term Loans (or any portion thereof) on any day which is not a
Business Day. The proceeds of the Term Loans shall be used by the Borrower for
the purchase of stock of E for M and the payment of the costs and expenses of
the Acquisition. Borrower may, at its option, without premium or penalty, prepay
the Term Loans in whole or in part, provided that any such prepayments shall be
made by Borrower on a prorata basis among the Term Loans, provided, however,
that no prepayments of the M&I Term Loan, the NBD Term Loan or the Wachovia Term
Loan may be made on any day other than the last day of any Interest Period in
effect for the M&I Term Loan, the NBD Term Loan or the Wachovia Term Loan, as
the case may be, during the term hereof. Each payment of principal, including
any such prepayments, shall be applied to the installments payable under the
Term Notes (as defined below) in their order of maturity.
 
         (a) Interest. Interest shall accrue on the unpaid principal amount of
     the Term Loans from time to time outstanding during each Interest Period at
     a rate per annum equal to the LIBOR Rate determined for such Interest
     Period plus one percent (1.0%). Interest shall be payable in arrears on the
     last day of each Interest Period during the term hereof and at maturity.
     Interest shall be computed on the basis of a 360 day year for the actual
     number of days elapsed. M&I is authorized to debit Borrower's account at
     M&I (Account No. 203491) by the amount of any interest payment which is due
     to M&I. NBD and Wachovia shall each provide Borrower with a statement of
     the amount of any interest payment which is due to NBD and to Wachovia,
     respectively. If all or a portion of the principal amount of any Term Loan
     made hereunder shall not be paid when due (whether at the stated maturity,
     by acceleration or otherwise), any overdue principal amount thereof shall
     bear interest at a rate per annum equal to the M&I Rate plus two percent
     (2.0%) (the Default Rate"). Any change in the Default Rate resulting from a
     change in the M&I Rate shall become effective as of the opening of business
     on the date on which such change in the M&I Rate shall become effective.

         (b) Term Notes. Term Loans made by M&I, NBD and Wachovia, respectively,
     shall be evidenced by three promissory notes of Borrower (the "Term Notes")
     substantially in the form of Exhibits A-1, A-2 and A-3 attached hereto,
     payable to the order of M&I, NBD and Wachovia, respectively, and each
     representing in the aggregate the obligation of Borrower to pay to M&I,
     NBD and Wachovia, respectively, the aggregate unpaid principal amount of
     the Term Loan made by such Bank, with interest thereon as provided in
     subsection l(a). Each Term Note (i) shall be

                                       2

 
     dated as of the date of this Agreement, (ii) shall be stated to mature on
     October 31, 2000, and (iii) shall be payable in eight (8) equal
     installments of principal in the amount of $3,750,000 each on the last day
     of April and October of each year commencing April 30, 1997.

          (c) Selection of Interest Period. Borrower shall select Interest
     Periods with respect to each Term Note. Each notice pursuant to which
     Borrower selects an Interest Period must be received by M&I, NBD or
     Wachovia, as the case may be, prior to 11:00 a.m. Milwaukee time (i) on the
     Effective Date with respect to the initial Interest Period or, (ii) with
     respect to subsequent Interest Periods, three (3) Business Days prior to
     the last day of the next preceding Interest Period. Each such notice shall
     be by telephone, telecopy or cable, confirmed immediately in writing,
     specifying therein the requested Interest Period and shall be irrevocable
     and binding on Borrower. In the event Borrower fails to provide notice of
     its selection of an Interest Period, the Interest Period which Borrower
     failed to select shall automatically be one month. Following receipt of
     Borrower's notice of its selection of an Interest Period, each Bank shall
     notify Borrower as soon as practicable of its determination of the LIBOR
     Rate for such Interest Period.

     2. Representations and Warranties. In order to induce the Banks to enter
into this Agreement and to make the loans herein provided for, and in
recognition of the fact that the Banks are acting in reliance thereupon,
Borrower hereby covenants, represents and warrants as follows:

          (a) Corporate Existence; Corporate Power. Borrower and the Significant
     Subsidiaries are each corporations duly organized, validly existing, and in
     good standing under the laws of their respective states of incorporation
     and are duly authorized under all applicable provisions of law to carry on
     their businesses as presently conducted. Borrower and the Significant
     Subsidiaries are each duly qualified as foreign corporations and are in
     good standing under the laws of each jurisdiction where their ownership,
     lease or operation of their respective properties or the conduct of their
     respective businesses requires such qualification and the failure to so
     qualify either individually or in the aggregate would have a material
     adverse effect on Borrower's or any Significant Subsidiary's financial
     condition or the conduct of their respective businesses.  Borrower
     has the corporate power and authority to enter into,

                                       3

 
     deliver, issue and perform all of its obligations under this Agreement and
     the Term Notes and to borrow hereunder.

          (b) No Legal Bar; Enforceable Obligations. The execution, delivery and
     performance of this Agreement, the Term Notes, and any other agreement,
     certificate or instrument delivered by Borrower to Banks in connection with
     this Agreement, prospective borrowings hereunder and use of the proceeds
     thereof by Borrower (i) have been duly authorized by all necessary
     corporate action, (ii) are not in violation of or in contravention of any
     provisions of the Articles of Incorporation and By-Laws of Borrower, (iii)
     will not violate any indenture, contract or agreement to which Borrower is
     a party or to which it is subject or any statute, rule or regulation
     binding upon Borrower, (iv) will not require any consent or approval of
     Borrower's stockholders and (v) will not result in, or require, the
     creation or imposition of any Lien on any of Borrower's properties or
     revenues pursuant to any requirement of law or contractual obligation of
     Borrower except as provided in this Agreement. This Agreement, the Term
     Notes and any other agreement, certificate or instrument delivered by
     Borrower to Banks in connection with this Agreement when duly executed and
     delivered on behalf of the Borrower will constitute legal, valid and
     binding obligations of Borrower enforceable against Borrower in accordance
     with their terms.

          (c) Litigation. Neither Borrower nor either of the Significant
     Subsidiaries is a party to any litigation or administrative proceedings,
     nor so far as it is known by Borrower is any litigation or administrative
     proceeding threatened against it or either of the Significant Subsidiaries
     which litigation or administrative proceedings, existing or threatened,
     would, if adversely determined, cause any material adverse change in
     Borrower's financial condition or in the conduct of the Borrower's or
     either of the Significant Subsidiaries' businesses.

          (d) Financial Condition. All copies of financial statements,
     documents, contracts, agreements and assignments which Borrower has
     furnished to Banks are true and correct in all material respects. There has
     been no material change in the property or business operations of Borrower
     or either of the Significant Subsidiaries since the date of the last
     financial statements delivered to Banks, except pursuant to the conduct of
     their ordinary business, and except as shall have been disclosed in writing
     by Borrower to Banks prior to the date of the execution of this Agreement.

                                       4

 
         (e) Taxes. Borrower and each of the Significant Subsidiaries have paid
     all federal, state and local taxes which are required to be paid by them
     (except for taxes being contested in good faith by appropriate proceedings
     and as to which reserves have been established by Borrower or either of the
     Significant Subsidiaries, as the case may be, in accordance with GAAP
     consistently applied, which reserves are set forth in Borrower's or the
     Significant Subsidiaries, financial statements).

         (f) Securities Laws; Investment Company Act; Board Regulations.
     Borrower and each of the Significant Subsidiaries have filed and will file
     when due all statements, if any, which it may be required to file under the
     provisions of any state or federal securities laws or regulations. Neither
     Borrower nor either of the Significant Subsidiaries is an "investment
     company" or a company "controlled" by an "investment company," within the
     meaning of the Investment Company Act of 1940, as amended, nor is Borrower
     or either of the Significant Subsidiaries engaged, principally or as one of
     its important activities, in the business of extending credit for the
     purpose of "purchasing" or "carrying" any "margin stock" within the
     respective meanings of each of the quoted terms under Regulation U of the
     Board of Governors of the Federal Reserve System as now and from time to
     time in effect.

         (g) Ownership of Property. Borrower and each of the Significant
     Subsidiaries own all of their assets that appear on their respective
     balance sheets free and clear of any Liens, except as previously disclosed
     in writing by Borrower or the Significant Subsidiaries to the Banks prior
     to the date hereof and except for financing leases referred to in
     Borrower's or the Significant Subsidiaries' financial statements.

         (h) Compliance with Laws. Borrower and each of the Significant
     Subsidiaries are in compliance in all material respects with all of the
     requirements of applicable federal, state and local statutes, regulations
     and ordinances relating to the business operations and the assets of the
     Borrower and of the Significant Subsidiaries ("requirements of law"), the
     violation of which could reasonably be expected to materially affect the
     Borrower on a Consolidated basis.

         (i) Environmental Matters. Borrower's and the Significant Subsidiaries'
     operations (a) are in compliance in all material respects with all of the
     requirements of

                                       5

 
     applicable federal, state and local environmental, health and safety
     statutes and regulations ("environmental laws"), and (b) are not the
     subject of any federal or state investigation evaluating whether any
     remedial action is needed to respond to a release of any toxic or hazardous
     waste or substance into the environment which could reasonably be expected
     to materially affect the Borrower on a consolidated basis. Borrower has not
     received any notice or claim to the effect that Borrower is or may be
     liable to any Person (including, without limitation, any individual or
     government, whether national, federal, state, county, city or municipal) as
     a result of the release of any toxic or hazardous waste or substance into
     the environment which could reasonably be expected to materially affect the
     Borrower. Borrower and each of the Significant Subsidiaries have all
     permits, licenses and approvals required under all applicable environmental
     laws and have paid all fees relating thereto and are in compliance with all
     terms and conditions thereof.

              (j) ERISA. All Plans maintained by Borrower and the Significant
     Subsidiaries are in compliance in all material respects with the applicable
     provisions of ERISA. Neither Borrower nor either of the Significant
     Subsidiaries has incurred any "accumulated funding deficiency" within the
     meaning of Section 302 of ERISA in connection with any Plan. There has been
     no "reportable event" within the meaning of Section 4034(b) of ERISA for
     any Plan the occurrence of which would have a material adverse effect on
     Borrower or the Significant Subsidiaries, nor has Borrower or either of the
     Significant Subsidiaries incurred any material liability to the Pension
     Benefit Guaranty Corporation.

         3. Affirmative Covenants of Borrower. Borrower covenants and agrees
that so long as any Term Note remains outstanding and unpaid or any amount is
owed to any one or more of the Banks, Borrower shall:

         (a) Financial Statements. Deliver to each Bank:

         a statement of cash flows of the Borrower for the period from the
         beginning of the current fiscal year to the end of such fiscal quarter,
         and a consolidated balance sheet of Borrower as at the end of such
         fiscal quarter, all in reasonable detail and certified by an authorized
         financial officer of Borrower, subject to changes resulting from year-
         end adjustments;

                                       6

         the end of each fiscal year, a statement of earnings, reconciliation of
         retained earnings, a statement of cash flows and a balance sheet of
         Borrower as at the end of such year, each prepared on a consolidated
         and consolidating basis, setting forth in each case in comparative form
         corresponding figures from the preceding annual audit, all in
         reasonable detail and accompanied by an opinion of independent public
         accountants of recognized standing selected by Borrower which opinion
         shall be without qualification as to the compliance of such statements
         and the balance sheet with GAAP;
    
             (iii) promptly upon transmission thereof, copies of all such
         financial statements, proxy statements, notices and reports as it
         shall send to its stockholders and copies of all registration
         statements (without exhibits) and all reports which it files with the
         Securities and Exchange Commission (or any governmental body or agency
         succeeding to the functions of the Securities and Exchange Commission);
         
             (iv) promptly upon receipt thereof, a copy of all other reports
         submitted to Borrower or either of the Significant Subsidiaries by
         independent accountants in connection with any annual, interim or
         special audit made by them of the books of Borrower or either of the
         Significant Subsidiaries;

          5.   Events of Default. An "Event of Default" shall be deemed to have

               (a)  Any representation or warranty made by Borrower in this
     Agreement, or in any certificate of Borrower furnished to Banks hereunder,
     shall prove to have been incorrect in any material respect as of the time
     when made.

               (b)  If Borrower shall fail to pay any interest or principal on
     any of the Term Loans when due hereunder or fail to pay when due any
     principal or interest on any of its other indebtedness to any one or more

               (c) Borrower shall default in the performance or observance of
     any covenant or agreement contained in this Agreement or in any other
     agreement between Borrower and any of the Banks; provided, however, that a

     agreement contained in Section 3 of this Agreement shall only constitute a
     default if the breach remains uncured for a period of thirty (30) days
     after written notice thereof from Banks to Borrower.

               (d)  Borrower or any Significant Subsidiary shall:

                    (i)  Apply for or consent to the appointment of a receiver,

                    (v)   File a voluntary petition in bankruptcy or a petition

          bankruptcy, reorganization or insolvency proceeding; or

                                      14

 
                        (vi)  Take any corporate action for the purpose of
          effecting any of the foregoing.

     Significant Subsidiary or of all or a substantial part of the assets of
     Borrower or such Significant Subsidiary, and such petition shall remain
     undismissed for any period of sixty (60) days.

                (f)  Borrower or either of the Significant Subsidiaries shall

     beyond any period of grace provided with respect thereto or in the
     performance of any other agreement, term or condition contained therein or
     in any agreement or security interest relating to any such obligation, if
     the effect of such default is to cause or permit the holder or holders of
     such obligation (or a trustee or agent on behalf of such holder or holders)
     to cause such obligation to become due prior to its stated maturity.

                (g)  A final judgment which, together with other outstanding
     final judgments against it or either of the Significant Subsidiaries,
     exceeds an aggregate of $1,000,000 shall be entered against Borrower or
     either of the Significant Subsidiaries and remains outstanding and
     unsatisfied or unstayed after sixty (60) days from the date of entry

     provided by law and suitable bond has been provided or other agreement made
     to stay execution of such judgment.

          6.  Rights Upon Default. If any of the Events of Default specified in
subsection 5(d) or 5(e) shall occur, the Term Notes and any other amounts owing
under this Agreement, the M&I Revolver Note, the Existing Loan Agreement and the
Existing Term Notes shall immediately become due and payable. If any other Event
of Default shall occur, any Bank may (i) by notice of default to Borrower,
declare such Bank's obligations hereunder terminated forthwith, whereupon such
obligations shall terminate, and/or (ii) by notice of default to Borrower and to
the other Banks, declare such Bank's Term Loan and all amounts owing to such
Bank hereunder and under such Bank's Term Note, and to the extent such Bank has
any interest therein, under the M&I Revolver

                                      15



 
Note and the Existing Term Notes, to be due and payable forthwith, whereupon the
same shall become immediately due and payable. Except as expressly provided
above in this Section, presentment, demand, protest and further notice of any
kind are hereby expressly waived. Notwithstanding the foregoing, the Banks'
obligations to maintain the confidentiality of any nonpublic financial
information of Borrower provided to the Banks pursuant to subsection 3(a) of
this Agreement shall survive the termination of its other obligations hereunder.

        In the event of any occurrence of any Event of Default, Borrower shall
pay all costs and expenses which may be incurred by the Banks with respect
thereto and with respect to the collection of any amounts due the Banks pursuant
hereto or the enforcement of any provisions hereof, including reasonable
attorneys' fees and expenses of litigation, and all such sums shall be and
become part of the indebtedness pursuant to this Agreement. In addition to and
not in lieu of any other right or remedy they may have at any time, the Banks at
any time and from time to time at their election, may (but they shall not be
required to) do or perform or comply with or cause to be done or performed or
complied with anything which Borrower may be required to do or comply with under
this Agreement if Borrower shall fail to do so; Borrower shall reimburse the
Banks upon demand for any reasonable cost or expense the Banks may pay or incur
in such respect, together with interest thereon at a per annum rate equal to the
Default Rate from the date of such demand until paid in full. The failure of the
Banks at any time or from time to time to exercise any right or remedy, whether
arising from or by virtue of any Event of Default or otherwise, shall not
constitute a waiver of any such right or remedy and shall not impair the right
of Banks to exercise such right or remedy or any other right or remedy
thereafter or to insist upon strict performance. No waiver of any right or
remedy by the Banks shall be valid or effective unless made in writing and
signed by an officer of each Bank. Any effective waiver of any right or remedy
shall not be deemed to constitute a waiver of any other right or remedy then
existing or which may thereafter arise or accrue. The remedies herein provided
are cumulative and not exclusive of any remedies provided by law. Upon the
occurrence of any Event of Default, and pursuant to the provisions of this
Section, any Bank may sue to enforce the obligations of Borrower to such Bank
pursuant to this Agreement.

        (a)  The provisions of this Agreement shall inure to the benefit of and 
be binding upon any successor to any of the parties hereto and shall extend and 
be available to any holder of the Term Notes and renewals thereof. Borrower may 
not assign or otherwise transfer its rights under this Agreement except with the
prior written consent of the Banks. None of the Banks shall participate, assign 
or otherwise transfer any portion of the loans which are the subject of this 
Agreement or its rights under this Agreement (a "Transfer") to any third party 
(other than an affiliate of such Bank or its holding company) without the prior 
written

                                      22

 
consent of the Borrower. In the event any Bank (the "Transferring Bank") intends
to make a Transfer to any third party (other than an affiliate of the 
Transferring Bank or its holding Company) the Transferring Bank shall provide 
written notice thereof to the other Banks indicating the principal amount of the
loan or loans the Transferring Bank intends to Transfer and the proposed third 
party transferee. For a period of thirty (30) days from the date of such notice,
either of the other Banks, by written notice thereof to the Transferring Bank 
may elect to require the Transferring Bank to make the intended Transfer to such
Bank. Any such election may be made with respect to all or any portion of the 
principal amount of the loan or loans proposed to be Transferred. If either or 
both of the other Banks make such an election, the Transferring Bank shall 
assign and transfer the loan or loans to the electing Bank in accordance with 
their respective elections or prorata based on the principal amount of loans 
outstanding held by each such Bank under this Agreement. If neither of the other
Banks has exercised such right of first refusal within such 30 day period, the 
Transferring Bank may, subject to the provisions of this Agreement, make the 
Transfer for which it has given notice.

        (b)  The Banks and the Borrower may, from time to time, enter into 
written amendments, supplements or modifications hereto for the purpose of 
adding provisions to any agreements, instruments or other documents hereunder or
for the purpose of changing in any manner the rights of the Banks or of the 
Borrower hereunder, and the Banks may execute and deliver to the Borrower a 
written instrument waiving, on such terms and conditions as the Banks may 
specify in such instrument, any of the requirements of this Agreement or any 
Default or Event of Default and its consequences. In the case of any waiver, the
Borrower and the Banks shall be restored to their former position and rights 
under this Agreement, and any Default or Event of Default waived shall be deemed
to be cured and not continuing. However, no waiver of a Default or Event of 
Default shall extend to any subsequent or other Default or Event of Default, or 
impair any right consequent thereon. No amendment, supplement, modification, or 
waiver shall be effective except if in writing and duly executed by both Banks 
and the Borrower.
 
       (c)  The Borrower's obligations to each Bank are separate and 
independent obligations, and each Bank shall be entitled to protect its rights 
hereunder and enforce the obligations of the Borrower to it and it shall not be 
necessary for any other Bank to be joined as an additional party

                                      23

     to any proceeding for such purpose. Nothing contained in this Agreement and
     no action taken by the Banks pursuant hereto shall be deemed to constitute
     the Banks to be a partnership, an association, a joint venture or any other
     kind of entity.

           (d) In the event that any date provided herein for any payment by
     Borrower shall be a Saturday, Sunday, or legal holiday, such payment date

     execution and the delivery of the Term Notes or renewals thereof.

     document delivered in connection herewith, upon the occurrence of any
     Event of Default, the Banks are hereby irrevocably authorized, at any time
     and from time to time without prior notice to Borrower, any such notice
     being expressly waived by Borrower, to set-off, appropriate and apply any
     and all deposits (general or special, time or demand, provisional or
     final), in any currency, and any other credits, indebtedness or claims, in
     any currency, in each case direct or indirect or contingent or matured or
     unmatured, at any time held or owing by the Banks to or for the credit of
     the account of Borrower, or any part thereof, in such amounts as Banks may
     elect, against and on account of the obligations and liabilities of
     Borrower to Banks hereunder or under the Term Notes, and claims of every
     nature and description of Banks against Borrower, whether arising

                (j) If any Bank which has accelerated its Term Note pursuant to

     receive any payment of all or part of its Term Loan, or interest thereon,
     (whether voluntarily or involuntarily, by setoff, pursuant to events or
     proceedings of the nature referred to in Section 6 here-


                                      26

 
     of, or otherwise) in a greater proportion than any such payment to any
     other Bank which has also accelerated its Term Note and is pursuing
     enforcement of its Term Note in good faith, if any, in respect of such
     other Banks' Term Loans, or interest thereon, such Benefitted Bank shall
     purchase for cash from such other Banks such portion of each such other
     Bank's Term Loan as shall be necessary to cause such benefitted Bank to
     share the excess payment ratably with each of such other Banks; provided,
     however, that if all or any portion of such excess payment is thereafter
     recovered from such benefitted Bank, or any portion of any Term Note which
     has been so purchased is thereafter determined by a court of appropriate
     jurisdiction to be unenforceable or subject to a valid defense, such
     purchase shall be rescinded, and the purchase price returned, to the extent
     of such recovery or unenforceability or defense together with such other
     Bank's prorata share of interest in respect of that portion of the 
     purchase price which is returned. The Company agrees that each Bank so
     purchasing a portion of another Bank's Term Loan may exercise all rights of
     payment (including, without limitation, rights of setoff) with respect to
     such portion as fully as if such Bank were the direct holder of such
     portion.
     
                (k) Any provision of this Agreement which is prohibited or
