                                   AMENDMENT

to as this "Amendment") entered into by and among ESTERLINE TECHNOLOGIES

the Subsidiaries (this and other capitalized terms used hereinafter having the
meaning assigned thereto in the Credit Agreement referred to below) listed on
the signature pages hereof, the financial institutions listed on the signature
pages hereto (such financial institutuions being hereinafter collectively
called the "Banks" and individually called a "Bank"), and CONTINENTAL BANK N.A.
("Continental") as agent for the Banks (in such capacity, together with any

                                  BACKGROUND:

         A.      Esterline and certain of its Subsidiaries (herein called the
"Original Companies"), the Banks and the Agent have entered into that certain
Amended and Restated Credit Agreement, executed as of January 25, 1991 and
dated and effective as of September 18, 1989 and heretofore amended (as so
amended, the "Original Credit Agreement").  The Original Credit Agreement was
an amendment and restatement of that certain Credit Agreement dated as of
September 18, 1989 (the "1989 Credit Agreement") among the Original Companies,
the Banks and the Agent.

         B.  The Companies desire to further amend the Original Credit
Agreement so as to, among other things, revise certain covenants and the
commitments of the Banks.

         C.  The Banks and the Agent are willing to agree to such amendments on
the terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the foregoing and the covenants
and conditions contained herein and for other good and valuable consideration
(the receipt of which is hereby acknowledged), the parties hereto, intending
legally to be bound, agree as follows:

         SECTION 1.  New Definition.

         The following new defined term is hereby added to Appendix X to the
Original Credit Agreement, to be placed in the proper alphabetical order:

                 "Restructuring Charge" shall mean the restructuring provision

         delivered to each Banks.

                 SECTION 2.  Amendments to Definitions.

         The following defined terms in Appendix X to the Original Credit
Agreement are hereby amended and restated in their entireties to read as
follows:

                 "Consolidated Income Available for Fixed Charges" shall mean
         for any period, the sum of (i) Consolidated Net Income for such
         period, plus (to the extent deducted in determining Consolidated Net
         Income), (ii) all provisions for any federal, state, or other income
         taxes made by Esterline and its Subsidiaries during such period, (iii)
         Fixed Charges for such period, (iv) amortization during such period of
         goodwill and intangibles resulting solely from Esterline's acquisition
         on September 27, 1989 of six Criton Technologies operating companies
         from The Dyson-Kissner-Moran Corporation, and (v) the Restructuring
         Charge.

                 "Funded Debt" shall mean (x) the consolidated Ratio
         Indebtedness of Esterline and its Subsidiaries, determined in
         accordance with generally accepted accounting principles, owed or
         guaranteed which by its terms matures more than one year from the date
         of creation (including any portion thereof payable within a year) or
         which may be renewed or extended at the option of the obligor for more
         than one year from such date whether or not theretofore renewed or
         extended, excluding Ratio Indebtedness which may be payable on demand
         (or within one year of creation) but which is incurred or issued under
         a revolving credit or similar agreement providing for borrowings (or
         renewables or extendibles) over a period of more than one year, unless
         such Ratio Indebtedness is required to be reflected on the balance
         sheet of the obligor as Funded Debt by generally accepted accounting
         principles, and (y) the consolidated Ratio Indebtedness of Esterline
         and its Subsidiaries, determined in accordance with generally accepted
         accounting principles, owed or guaranteed which by its terms matures
         less than one year from the date of creation unless (during the
         Adjusted Twelve-Month Period with respect to which Funded Debt is
         being calculated) there shall have been a period of 60 consecutive
         days during which no such Ratio Indebtedness was outstanding.

                 "Interest Coverage Ratio" shall mean, as of any End Date, the
         ratio of (x) the excess of (i) Consolidated Net Income determined

         Twelve-Month Period





   3
         ending on such End Date, over (ii) Capital Expenditures made by 
         Esterline and the Subsidiaries during such Adjusted Twelve-Month 
         Period, to (y) Interest Outlay for such Adjusted Twelve-Month Period.

                 "EBIT/I Ratio" shall mean, as of any End Date, the ratio (x)
         consolidated Net Income of Esterline and the Subsidiaries determined
         without deducting interest and tax expense for the Adjusted Twelve
         Month Period ending on such End Date, to (y) Interest Outlay for such
         Adjusted Twelve Month Period; provided, however, for purposes of
         calculating the Original Margins under Section 3.2 and the Letter of
         Credit Fee pursuant to Section 4.4 with respect to any Adjusted
         Twelve-Month Period that includes Esterline's fourth fiscal quarter of
         1993, Consolidated Net Income of Esterline and the Subsidiaries shall
         be determined without deducting interest and tax expense for the
         Adjusted Twelve-Month Period ending on the relevant End Date and
         without deducting the Restructuring Charge.

         Section 3.  Reduction of Facility A Commitments.  The Banks
acknowledge that the Facility A Borrowers have permanently reduced the
aggregate amount of the Facility A Commitments to $35,000,000.

         Section 4.  Amendment to Net Worth Covenant.  The first sentence of
Section 10.5(a) of the Original Credit Agreement shall be amended and restated
(except with respect to any period ending prior to the date hereof) in its
entirety to read as follows:

                 Not permit Adjusted Consolidated Net Worth to be less than the
         greater of (x) the Net Worth Minimum (as defined in the next
         sentence), and (y) the sum of $41,300,000 plus 50% of Consolidated Net
         Income (without reduction for losses) from and including the first day
         following the October, 1990 End Date to the date of calculation.

The second sentence of Section 10.5(a) of the Original Credit Agreement is
amended by deleting the figure "77,000,000" where it appears in clause (v)
thereof, and substituting therefor the figure "$49,800,000" and by deleting the
figure "$80,000,000" where it appears in clause (vi) thereof, and substituting
therefor the figure "$52,800,000".

         SECTION 5.  Senior Note Agreement Amendment.  The Banks waive Section
10.30 of the Original Credit Agreement to the extent necessary to permit the
Companies to execute and deliver an amendment to the Senior Note Agreement
substantially in the form of Schedule I hereto.

obligations under the Original Credit Agreement to Seafirst Bank, and (ii)

                 (b)  The representations and warranties of the companies set

         the extent that such warranties specifically relate to an earlier
         date.

                 (d)  After giving effect to this Amendment, no Event of
         Default or Unmatured Event of Default shall have occurred and be

         counterparts and by different parties on separate counterparts, and
         each such counterpart shall be deemed to be an original, but all such
         counterparts shall together constitute but one and the same amendment.

                 (d)  Any reference to the Original Credit Agreement or the
         1989 Credit Agreement contained in any notice, request, certificate or
         other document executed concurrently with or after the Effective Date
         shall be deemed to be a reference to the Amended Agreement.  Except as
         expressly modified hereby, the Loan Documents are hereby ratified and
