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 30, 2004, American Technical Ceramics Corp. (the "Company")
entered into a Loan and Security Agreement (the "Credit Agreement") with
Commerce Bank, N.A. ("Commerce Bank"), establishing a $5,000,000 one-year
revolving credit facility (the "Facility"). 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 the first anniversary of the closing date of the Facility (e.g.,
November 30, 2005). 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 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.
