                               RECITALS

A.  Borrower and Bank entered into an Asset Based Loan and Security
    Agreement dated April 14, 1995, which was later amended on July 31,
    1997, April 29, 1998, September 8, 1998 and June 30, 1999 ("Agreement"),
    whereby Bank has made certain loans to Borrower in the aggregate amount
    of $4,900,000.00 ("Loans")

B.  The Loans are evidenced by (a) Borrower's Amended and Restated Revolving
    Asset Promissory Note in the amount of $3,000,000.00, (b) 'Borrower's
    Amended and Restated Term Loan Promissory Note in the amount of
    $1,400,000.00, and (c) Borrower's Amended and Restated Equipment
    Acquisition Promissory Note in the amount of $500,000.00, each of which
    are hereinafter collectively referred to as the "Notes".

C.  Bank and Borrower wish to amend the Agreement to change the interest
    rate or rates charged under the Notes to add Techdyne, Inc. as a
    guarantor and to modify the financial covenants contained in the
    Agreement.

NOW THEREFORE, the Borrower and Bank agree as follows:

1.  The Agreement is hereby amended by adding Section 2.6 which shall read
    as follows:

    Interest Rate.  Amounts advanced to Borrower under the Notes shall bear
    -------------
    interest at (i) a fluctuating rate equal to the Prime Rate  (as defined
    herein) charged by Bank, minus one-quarter of one percent (.25%) ("Prime
    Rate Election"); or (ii) at a fixed rate equal to the relevant Quoted
    LIBOR Rate plus two and one-half percent (2.50%) per annum, as elected
    by Borrower in the manner set out herein ("LIBOR Rate Election").

    Interest shall be calculated on a 360-day year basis and shall be due
    and payable on the first day of each calendar month (but charged based
    on actual days) during the term of and at maturity of the respective
    Notes.  In the case of a Prime Rate Election, the interest rate shall
    be adjusted, whenever necessary, to reflect any change in the Prime
    Rate then in effect at the Bank, and such adjustment shall be effective
    on the date such change is announced as effective by the Bank.  Such
    new rate shall remain in effect until the next date an adjustment is
    required or until the Borrower makes a LIBOR Rate Election or the
    respective Note is paid in full.

       2.6.1 Interest Periods.   Commencing upon the execution of this
             ----------------
    Amendment, or at the time Borrower gives any notice of borrowing relating
    to the Revolving Asset Loan, or at the time Borrower gives notice of
    conversion of any Loan subject to this Section 2.6 to a Quoted LIBOR
    Rate, which notice shall be given at least three (3) Business Days prior
    to the expiration of an existing Interest Period, and provided Borrower
    is not otherwise in default hereunder, Borrower shall have the right to
    elect the Interest Period applicable to a Quoted LIBOR Rate Election by
    giving the Bank notice thereof, which Interest Period shall be a thirty
    (30), sixty (60), ninety (90) or one hundred eighty (180) day period,
    provided, however, that Borrower shall have no right to elect an Interest
    Period that would extend beyond the maturity date of the Revolving Asset
    Loan, the Term Loan or the Equipment Acquisition Loan.  In the case of
    the Revolving Asset Loan, the Interest Period may be selected at the
    time a request for an advance is made, in the manner required by the
    Bank for giving such notice.  In the case of the Revolving Asset Loan,
    the Term Loan and the Equipment Acquisition Loan, the Interest Period
    and applicable interest rate may also be selected by giving notice in
    accordance with Section 2.6.2 below.  The Interest Period may commence
    at any time after proper notice, and each Interest Period occurring
    thereafter, if any, in respect of such a Loan shall commence on the day
    on which the next preceding Interest Period expires.  If any Interest
    Period would otherwise expire on a day which is not a business day,
    such Interest Period shall expire on the next succeeding business day.
    If upon the expiration of any Interest Period for a Quoted LIBOR Rate
    Election, Borrower has failed to repay the borrowing or elect a new
    Interest Period to be applicable, Borrower shall be deemed to have
    elected to convert to or continue (as the case may be) with a Prime
    Rate Election effective as of the expiration date of such current
    Interest Period.

       2.6.2 Continuation and Conversions.  Provided that no Event of Default
             ----------------------------
    then exists, Borrower shall have the option, subject to the provisions of
    Sections 2.6.1 and 2.6.3 and the following provisions of this Section
    2.6.2, on the first day following expiration of an Interest Period in
    the case of a Quoted LIBOR Rate Election  or at any time in the case of
    a Prime Rate Election, to continue a previously selected Quoted LIBOR
    Rate Election for an additional Interest Period or to convert all or a
    portion of the outstanding principal amount of under any Prime Rate
    Election to a Quoted LIBOR Rate Election, provided that the outstanding
    principal amount of Loans being continued as or converted into a Quoted
    LIBOR Rate Election shall be at least Two Hundred Fifty Thousand Dollars
    U.S. ($250,000.00).  Each such conversion shall be effected by Borrower
    giving the Bank prior notice in the form as required by the Bank,
    specifying the Loan and amount of such Loan to be so continued or
    converted, and the Interest Period.

    2.6.3 Increased Costs, Illegality Etc.
          -------------------------------

       A. In the event the Bank shall have determined (which determination
    shall, absent manifest error be final and conclusive and binding upon
    all parties):

<PAGE>  2

          (i) on any date for determining the rate applicable to any Quoted
    LIBOR Rate Election for any Interest Period, that by reason of any
    changes arising after the date of this Agreement affecting the
    interbank Eurodollar market, adequate and fair means do not exist
    for ascertaining the applicable interest rate on the basis provided for
    in the definition of such Quoted LIBOR Rate Election; or

          (ii) at any time, that by reason of (x) any change since the date
    of this Agreement in any applicable law or governmental rule, regulation,
    guideline or order (or any interpretation thereof and including the
    introduction of any new law or governmental rule, regulation, guideline
    or order) (such as for example, but not limited to, a change in capital
    adequacy requirements or in official reserve requirements, but, in all
    events, excluding reserves required under Regulation D to the extent
    included in the computation of the Quoted LIBOR Rate and/or (y) other
    circumstances affecting a Bank or the interbank Eurodollar market or the
    position of such Bank in such market, the Quoted LIBOR Rate or T-Bill
    Rate shall not represent the effective pricing to such Bank for funding
    or maintaining the affected Quoted LIBOR Rate Election; or

          (iii) at any time, that the making or continuance of any Quoted
    LIBOR Rate Election has become unlawful by compliance by a Bank in good
    faith with any law, governmental rule, regulation, guideline or order,
    or has become impracticable as a result of a contingency occurring after
    the date of this Agreement which materially and adversely affects the
    interbank Eurodollar market; then, and in any such event, the Bank shall
    on such date give notice to Borrower of such determination.  Thereafter,
    (x) in the case of clauses (i) and (ii) above, Borrower shall pay to each
    Bank, upon written demand therefor, such additional amounts (in the form
    of an increased rate of, or a different method of calculating, interest
    or otherwise as such Bank in its sole discretion shall determine) as
    shall be required to cause such Bank to receive interest with respect to
    its affected Quoted LIBOR Rate Election at a rate per annum which shall
    equal the effective pricing to the Bank to make or maintain such Quoted
    LIBOR Rate Election, respectively, plus 2.25% per annum (a written notice
    as to additional amounts owed such Bank, showing the basis for the
    calculation thereof, submitted to Borrower by such Bank shall, absent
    manifest error, be final and conclusive and binding upon all of the
    parties hereto) and (y) in the case of clause (iii), take one of the
    actions specified in Section 2.6.3.C. below, as promptly as possible and,
    in any event, within the time period required by law.

       B. If the Bank determines that (i) maintenance of any Quoted LIBOR
    Rate Election would violate any applicable law, rule, regulation, or
    directive, whether or not having the force of law, (ii) deposits of a
    type and maturity appropriate to match fund any Quoted LIBOR Rate
    Election are not available , (ii) the Quoted LIBOR Rate does not
    accurately reflect the cost of making or maintaining a Quoted LIBOR
    Rate Election, then the Bank shall suspend the availability of the
    affected rate option and require any Quoted LIBOR Rate Election
    outstanding under an affected rate option to be repaid.

<PAGE>  3

       C. At any time that any of its Quoted LIBOR Rate Elections are affected
    by the circumstances described in Section  2.6.3.A. (iii), Borrower shall
    either (x) if the affected Quoted LIBOR Rate Election is then being made
    pursuant to an initial borrowing or a conversion, cancel said borrowing
    or conversion by giving the Bank telephonic notice confirmed in writing
    thereof on the same date that Borrower was notified by the Bank pursuant
    to Section 2.6.3.A, or (y) if the affected Quoted LIBOR Rate Elections
    are then outstanding, upon at least two (2) Business Days' notice to
    the Bank, require the Bank to convert each affected Quoted LIBOR Rate
    Election into a Prime Rate Election.

       2.6.4 Compensation.  Borrower shall compensate the Bank upon written
             ------------
    request (which request shall set forth the basis for requesting such
    amounts), for all reasonable losses, expenses and liabilities (including,
    without limitation, any interest paid by the Bank to lenders of funds
    borrowed by them to make or carry  a Quoted LIBOR Rate Election to the
    extent not recovered by the Bank in connection with the re-employment
    of such funds), which the Bank may sustain: (i) if for any reason
    (other than a default by the Bank) a borrowing of, or conversion from
    or into, Quoted LIBOR Rate Election does not occur on a date specified
    therefor in a notice of borrowing or notice of conversion (whether or
    not withdrawn), or (ii) as a consequence of any other default by Borrower
    to repay its Quoted LIBOR Rate Elections when required by the terms of
    this Agreement.

       2.6.5 Rate Adjustment.  Notwithstanding anything to the contrary
             ---------------
    contained herein, the Interest Rate charged under the Notes shall be
    reduced for the remaining term of each such Note to (i) a fluctuating
    rate equal to the Prime Rate charged by Bank, minus one half of one
    percent (.50%); or (ii) a fixed rate equal to the relevant Quoted LIBOR
    Rate plus two and one quarter percent (2.25%), effective as of January
    1, 2001 if the following conditions are satisfied:

          a.  The Debt Service Coverage Ratio (as defined herein) shall be
              greater than 2.00 to 1.00 for the year ending December 31, 2000;

          b.  The ratio of Consolidated Liabilities to Consolidated Tangible
              Net Worth (both as defined herein) shall be not more than 2.25
              to 1.00 as of December 31, 2000; and

          c.  There has not occurred an Event of Default under the Agreement
              or under any loan from Bank to Techdyne, Inc.

       In the event the above conditions are satisfied, Borrower agrees to
    execute and deliver to Bank, an Amended and Restated Revolving Asset Note,
    an Amended and Restated Term Loan Note, and an Amended and Restated
    Equipment Acquisition Note each setting out the new interest rate set out
    herein, which new Notes shall be effective as of January 1, 2001.
