THIS SECOND MODIFICATION OF CONSTRUCTION TO PERMANENT LOAN PROMISSORY NOTE AND
OPEN-END CONSTRUCTION TO PERMANENT MORTGAGE DEED (the "AGREEMENT"), entered into
as of the ____ day of April, 1996, by and between EDAC TECHNOLOGIES CORPORATION,

FLEET NATIONAL BANK OF CONNECTICUT F/K/A SHAWMUT BANK CONNECTICUT, N.A. a
national banking association, having an office at 777 Main Street, Hartford,
Connecticut 06115 (the "LENDER").

                             W I T N E S S E T H:

     1.   On October 3, 1985, the Lender and the Borrower entered into a certain
Revolving Loan and Security Agreement which has been (a) amended and restated in
its entirety by a certain Fifth Amended and Restated Revolving Loan, Term Loan,
Equipment Loan and Security Agreement dated February 28, 1995, (b) amended by a
certain Sixth Amendment to Revolving Loan, Term Loan, Equipment Loan and
Security Agreement dated July 31, 1995 and (c) amended by a certain Seventh

in the Loan Agreement.

     2.   Pursuant to the Loan Agreement, the Borrower executed a certain
Construction to Permanent Loan Promissory Note dated July 31, 1995 in the

amended pursuant to a certain Modification of Construction to Permanent Loan
Promissory Note and Open-End Construction to Permanent Mortgage Deed (the

things, an Open-End Construction to Permanent Mortgage Deed from the Borrower in
favor of Lender dated August 3, 1995 and recorded in Volume 502 at Page 1024 of
the Farmington Land Records, which was modified pursuant to the Modification (as
modified, the "MORTGAGE"), encumbering certain real property located in the Town

Loan Agreement, Note, Mortgage and related documents are collectively referred
to as the "LOAN DOCUMENTS".
 
     3.   The Borrower has requested that the Lender extend certain other loans
from the Lender to the Borrower.

     4.   As a condition to the extension, the Lender requires the Borrower to
enter into this Agreement.

     5.   In consideration of the foregoing, and for One ($1.00) Dollar and
other valuable consideration received to its satisfaction, the Borrower agrees
to modify the terms and conditions of the Note and Mortgage as more specifically
set forth in this Agreement.

               a.   The resolutions previously adopted by the Board of Directors
of the Borrower and provided to the Lender have not in any way been rescinded or

     B.   Modification of Note.
          -------------------- 

          The Borrower and the Lender agree that the terms of the Note are
hereby modified in accordance with the following:

          1.   Paragraph (1) entitled "Adjustment Date" on page two of the Note
is hereby deleted in its entirety.

          2.   Paragraph (15) entitled "Permanent Interest Rate" on page four of
the Note is hereby deleted in its entirety and the following is substituted in
lieu thereof:

               (15) "PERMANENT INTEREST RATE" shall mean a variable rate equal
               to the Base Rate plus one (1%) percent.

               The Lender may, in its sole and absolute discretion, reduce the
               interest rate payable under this Note to a per annum rate equal
               to the Base Rate plus one-half of one (0.5%) percent.  Nothing
               contained herein shall be deemed to be an express or implied
               commitment or intention by or on the part of the Lender to so
               reduce the interest rate.

          3.   Section D entitled "D. PERMANENT LOAN TERMS." on page six of the
                                   ------------------------                    
Note is hereby deleted and replaced with the following:

               From the Conversion Date, the Permanent Interest Rate shall be
               payable upon the principal amount of the Permanent Loan at the
               Permanent Interest Rate.  The Permanent Interest Rate shall
               continue to be payable until the imposition of the Permanent
               Default Rate (hereinafter defined), or until the Permanent Loan
               is paid in full, whichever is applicable.

                                       3

 
               Commencing on the first day of the month following the Conversion
               Date, (a) payments of principal in the amount of $5,555.56 and
               (b) payments of accrued interest at the Permanent Interest Rate
               shall be paid on the first day of each month.  Each installment
               shall be applied first to the payment of late charges, then to
               accrued and unpaid interest and the balance on account of the
               principal of the Permanent Loan.  If not sooner paid, the entire
               unpaid principal balance of the Permanent Loan, with interest,
               shall be due and payable on the Maturity Date.

               Upon the occurrence of an Event of Default, or after the Maturity
               Date, interest shall accrue at four percent (4%) per annum above
               the Permanent Interest Rate in effect (the "PERMANENT DEFAULT
               RATE").  The Permanent Default Rate shall be adjusted whenever a
               change in the Base Rate occurs, so that the Permanent Default
               Rate shall remain at all times four (4%) percent per annum above
               the Permanent Interest Rate.  Any such adjustment in the
               Permanent Default Rate shall be effective simultaneously with a
               change in the Base Rate.

          4.   Section G. entitled "G. PREPAYMENT OF LOAN." on page eight of the
                                   ------------------------                     
Note is hereby deleted in its entirety and the following is substituted in lieu
thereof:

               The Borrower may prepay this Note in whole or in part at any time
               without penalty.  All such prepayments shall be applied on
               account of principal remaining unpaid and shall be accompanied by
               payment of unpaid late charges and accrued and unpaid interest,
               if any, thereon.  All partial prepayments of principal shall be
               credited to the unpaid principal of this Note in the inverse
               order of maturity and shall not affect the Borrower's obligation
               to make the regular installments required hereunder until this
               Note is fully paid.

     C.   Modification of Mortgage.
          ------------------------ 

          The Borrower and Lender hereby agree that the terms of the Mortgage
are hereby modified in accordance with the following:

          1.   Any and all references in the Mortgage to the term "Note" or
words of similar import shall be deemed to mean and refer to the Note as
modified by this Agreement.

          2.   The form of the Note attached as Schedule D to the Mortgage is
                                                ----------                   
hereby modified in accordance with Section B. above.

                                       4

 
     D.   Miscellaneous
          -------------

          1.   Except as specifically modified hereby, all of the terms and
conditions of the Note and Mortgage shall remain in full force and effect, and
Borrower hereby ratifies and affirms each of its respect obligations, terms,
conditions, covenants, representations and warranties contained therein, except
to the extent expressly modified hereby. Borrower agrees to be bound by the
terms and conditions of said instruments, as modified by this Agreement.
 
          2.   The rights and duties of the parties under this Agreement shall
be governed by the laws of the State of Connecticut.

          3.   This Agreement shall be binding upon the Borrower, the Lender and
each of their respective successors and assigns.

          4.   Nothing contained in this Agreement shall constitute a repayment
of the Note, or affect the priority of the lien of the Mortgage.

     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
as a sealed instrument by their duly authorized representatives as of the date
first above written.
