for the period ended September 29, 1991.

         C.      On December 10, 1992, TT and Bank entered into a certain

with Section 7.2(H) of the Loan Agreement, as amended, commencing with the
quarter ending December 31, 1992.

         E.      On August 2, 1993, TT and Bank entered into a certain Third
Amendment To The Revolving Loan And Security Agreement (the "Third Amendment")
to provide for (1) an increase in the maximum principal amount of borrowings
under the Revolving Loan from $25,000,000 to $35,000,000 (inclusive of the
issuance by Bank to TT of a maximum of $5,000,000 of standby letters of

         F.      TT has established ECA, Inc., a wholly-owned subsidiary of TT,

worldwide basis.

         G.      Borrowers have requested that Bank make available to ECA, Inc.
funds under the Revolving Loan in accordance with the provisions of the Loan
Agreement, as amended.

         H.      In consideration for Bank agreeing to loan and re-loan funds
to ECA, Inc. under the Revolving Loan in accordance with the provisions of the
Loan Agreement, as amended, ECA, Inc. desires to (1) assume as co-obligor all
obligations and liabilities of Borrowers due and owing to Bank now or hereafter
arising under the Loan Agreement, as amended, and (2) grant to Bank a security
interest in and to its Collateral in accordance with the provisions of this
Fourth Amendment.

amended, to (1) add ECA, Inc. as a co-obligor for the repayment of all loans to
Borrowers by Bank and (2) provide for such other amendments and modifications
as are set forth in the provisions of this Fourth Amendment.

         J.      Due to the affiliation and financial interdependence of
Borrowers, Bank and Borrowers have determined that it would be in their
respective best interests for each Borrower to be a joint and several obligor
of each other Borrower's obligations to Bank in accordance with the provisions
set forth in the Loan Agreement, as amended by the First Amendment, the Second
Amendment, the Letter Agreement, the Third Amendment, and this Fourth Amendment.
