ITEM 1.01.    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         The disclosure set forth below under Item 2.03 (Creation of a Direct
Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of
a Registrant) is hereby incorporated by reference into this Item 1.01.

ITEM 2.03.    CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER
              AN OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT.

         On November 28, 2005, Commerce Bank, N.A. ("Commerce Bank") notified
American Technical Ceramics Corp. (the "Company") that is has agreed to renew
the Company's $5,000,000 one-year revolving credit facility (the "Facility") for
an additional term. Under the terms of the Facility, the Company may request
advances from time to time in increments of $100,000 to finance short-term
working capital needs and stand-by and documentary letters of credit. (The
aggregate obligations in respect of all letters of credit cannot exceed
$2,000,000.) The outstanding principal balance under the Facility shall bear
interest at the "Prime Rate" of interest as published in the "Money Rates"
section of The Wall Street Journal. The outstanding principal balance must be
paid in full on November 30, 2006. In addition, there must be at least one
period of 30 consecutive days during the term of the Facility during which the
outstanding principal balance under the Facility equals zero.

         The Company's obligations under the Facility are guaranteed by its
wholly-owned subsidiary, American Technical Ceramics (Florida), Inc.
("ATC-Florida"), and are secured by a lien on the Company's accounts receivable
and inventory. ATC-Florida's obligations under its guaranty are also secured by
a lien on its accounts receivable and inventory.

         The agreement relating to the Facility (the "Credit Agreement")
contains customary conditions precedent to any draw down under the Facility and
customary covenants, including minimum tangible net worth and minimum leverage
ratios. The Company's obligations under the Credit Agreement may be accelerated
upon the occurrence of customary events of default, including, among others,
failure to make payments of principal or interest or other fees and expenses due
under the Facility; failure to comply with covenants and conditions contained in
the Credit Agreement; breaches or defaults under any other document or agreement
entered into in connection with the Facility; defaults under certain other
indebtedness; the occurrence of uninsured losses, or the entry of a judgment
against the Company which is not vacated, discharged, satisfied or bonded, in
excess of certain specified amounts; breaches of other material agreements
between the Company and Commerce Bank; certain bankruptcy-related events of
default; cessation of operations; or a change of control of the Company.

         As of the date hereof, the Company has no outstanding borrowings under
the Facility.
