                               ------------------

         This Agreement is made this 25th day of November, 1998, by AMERICAN
TECHNICAL CERAMICS CORP. (the "Borrower"), whose address is 17 Stepar Place,
Huntington Station, New York 11746, in favor of NATIONSBANK, N.A. (the "Bank"),
successor by merger to Barnett Bank, N.A., whose address is 50 North Laura

                                    Recitals
                                    --------

         The Borrower and the Bank have executed an Amended and Restated Loan
Agreement (as amended or restated from time to time, the "Loan Agreement") of
even date herewith. The Borrower, pursuant to the Loan Agreement, has executed
and delivered or may from time to time execute and deliver: (a) a Sub-Line
Promissory Note (as amended, extended or renewed from time to time, the
"Sub-Line Note") of even date herewith in the original Principal amount of
$3,500,000 in favor of the Bank; and (b) one or more Term Notes (as defined in
the Loan Agreement). The Sub-Line Note and the Term Notes are collectively
referred to herein as the "Notes". The Borrower has agreed to secure certain
obligations in accordance with the terms hereof.

         Now therefore, for good and valuable consideration, the Borrower
agrees as follows:

         1. Security Interest. The Borrower hereby gives the Bank a continuing
            ------------------
and unconditional security interest (the "Security Interest") in, and assigns
to the Bank, the following assets (collectively, the "Collateral"): (a) all
equipment and other assets (collectively, the "Equipment") purchased or
financed with the proceeds of the Equipment Line of Credit (as defined in the
Loan Agreement) (which Equipment shall be described in a separate schedule or
schedules which shall be updated from time to time as appropriate and, if
required by the Bank, attached to this Agreement); and (b) all parts,
accessories, attachments, additions, replacements, accessions, substitutions,
increases, distributions and proceeds to, of and from the Equipment in any form
(including, without limitation, insurance proceeds) together with all records
(including, without limitation, computer tapes, disks and records) relating
thereto.

         2. Indebtedness Secured. The Security Interest secures payment when
            ---------------------
due of all Indebtedness (as defined herein) to the Bank. As used in this
Agreement, the term "Indebtedness" means all principal, interest, costs,
expenses and other amounts now or hereafter due under the Notes (and each of
them) (including, without limitation, all principal amounts advanced thereunder
before, on or after the date hereof).

         3. Warranties of Borrower. The Borrower warrants and so long as this
            -----------------------
Agreement continues in force shall be deemed continuously to warrant that:

                  (a) The Borrower is the owner of the Collateral free of all
         security interests or other encumbrances, except the Security
         Interest.

                  (b) The Borrower is authorized to enter into the Security
         Agreement.

                          _______________________________________
                          _______________________________________

                  (e) The chief executive office of the Borrower is at the
         address set forth in the introductory paragraph of this Agreement. The
         Borrower does not operate under any trade names.

         4. Covenants of Borrower. So long as this Agreement has not been
            ----------------------
terminated as provided hereafter, the Borrower: (a) will defend the Collateral
against the claims of all other persons; (b) will keep the Collateral free from
all security interests or other encumbrances, except the Security Interest; (c)
will not assign, deliver, sell, transfer, lease or otherwise dispose of any of
the Collateral or any interest therein without the prior written consent of the

consistently applied, accurate and complete records concerning the Collateral
and upon the Bank's request will mark any of such records to give notice of the
Security Interest and will permit the Bank or its agents, upon reasonable
advance notice, to inspect the Collateral during normal business hours and to
audit and make abstracts of such records or any of the Borrower's books,
ledgers, reports, correspondence and other records relating to the Collateral;
(e) upon demand, will deliver to the Bank any documents of title and any
chattel paper representing or relating to the Collateral or any part thereof,
schedules, invoices, shipping or delivery receipts, purchase orders, contracts
or other documents representing or relating to purchases or other acquisitions
or sales or leases or other dispositions of the Collateral and proceeds thereof
and any and all other schedules, documents and statements relating to the
Collateral which the Bank may from time to time reasonably request; (f) without
the Bank's written consent, will not make or agree to make any alteration,
modification or cancellation of or substitution for any Collateral (except,
however, for alterations and modifications made in the ordinary course of
business in a manner consistent with past practices); (g) will keep the
Collateral at the address specified above until the Bank is notified in writing
of any change in its location within the State but the Borrower will not remove
the Collateral from the State nor change the location of the Borrower's chief
executive office without the written consent of the Bank; (h) will permit the
Bank or its agents to inspect the Collateral; (i) will keep the Collateral in
good condition and repair (reasonable wear and tear excepted) and will not use
the Collateral in violation of any provisions of this Agreement, any applicable
statute, regulation or ordinance or any policy of insurance insuring the
Collateral; 6) will execute and deliver to the Bank such financing statements
and other documents requested by the Bank, and take such other action and
provide such further assurances as the Bank may deem advisable to evidence,
perfect or enforce the Security Interest created by this Agreement; (k) will
pay all taxes, assessments and other charges of every nature which may be
levied or assessed against the Collateral (except, however, that the Borrower
shall be entitled to dispute taxes, assessments and other charges in good
faith); (l) will insure the Collateral

                                       2
<PAGE>

against risks by obtaining policies (none of which shall be cancellable without
at least 30 days prior written notice to the Bank) in coverage, form and amount
and with companies reasonably satisfactory to the Bank, containing a loss payee
provision in favor of the Bank, and at the Bank's request will deliver each
policy or certificate of insurance therefor to the Bank; (m) will prevent any
part of the Collateral from becoming an accession to other goods not covered by
this Agreement; and (n) if any certificate of title may be issued with respect
to any of the Collateral, will cause the Bank's interest under this Agreement
to be noted on the certificate and will deliver the original certificate to the
Bank.

         5. Verification. The Bank may verify or audit any Collateral in any
            -------------
manner and through any medium which the Bank may deem appropriate, and the
Borrower shall furnish such assistance as the Bank may reasonably require in
connection therewith.

         6.       Default.
                  --------

                  (a) Each of the following shall constitute an "Event of
         Default" hereunder: (i) the occurrence of an Event of Default under
         the Loan Agreement; (ii) failure by the Borrower to perform in any
         material respect any material obligations of the Borrower under this
         Agreement, time being of the essence; (iii) material falsity in any
         certificate, statement, representation, warranty or audit at any time
         furnished by or on behalf of the Borrower or any endorser or guarantor
         or any other party liable for payment of all or part of the
         Indebtedness, pursuant to or in connection with this Agreement; or
         (iv) any attachment or levy against any material portion of the
         Collateral or any other occurrence which inhibits the Bank's free
         access to any material portion of the Collateral.

                  (b) Upon the occurrence of an Event of Default, the Bank may:
         (i) declare all or any part of the Indebtedness due without notice to
         the Borrower; and (ii) exercise such other remedies and rights as are
         available hereunder, under the Loan Agreement or otherwise.

                  (c) Upon the occurrence of any Event of Default, the Bank's
         rights with respect to the Collateral shall be those of a secured
         party under the Uniform Commercial Code and any other applicable law
         in effect from time to time. The Bank shall also have any additional
         rights granted herein and in any other agreement now or hereafter in
         effect between the Borrower and the Bank. If requested by the Bank,
         the Borrower will assemble the Collateral and make it available to the
         Bank at a place to be designated by the Bank.

                  (d) The Borrower agrees that any notice by the Bank of the
         sale or disposition of the Collateral or any other intended action
         hereunder, whether required by the Uniform Commercial Code or
         otherwise, shall constitute reasonable notice to the Borrower if the
         notice is mailed by regular or certified mail, postage prepaid, at
         least ten days before the action to the Borrower's address as
         specified in this Agreement or to any other address which the Borrower
         has specified in writing to the Bank as the address to which notices
         shall be given to the Borrower.

<PAGE>

                  (e) The Borrower shall pay all costs and expenses incurred by
         the Bank in enforcing this Agreement, realizing upon any Collateral
         and collecting any Indebtedness (including a reasonable attorneys'
         fee) whether suit is brought or not and whether incurred in connection
         with collection, trial, appeal or otherwise and, to the extent of the
         Borrower's liability for repayment of any of the Indebtedness, shall
         be liable for any deficiencies in the event the proceeds of
         disposition of the Collateral do not satisfy the Indebtedness in full.

         7.       Miscellaneous.
                  --------------

                  (a) The Borrower authorizes the Bank at the Borrower's
         expense to file any financing statements relating to the Collateral
         (without the Borrower's signature thereon) which the Bank deems
         appropriate and the Borrower irrevocably appoints the Bank as the
         Borrower's attorney-in-fact to execute any such financing statements
         in the Borrower's name and to perform all other acts which the Bank
         deems appropriate to perfect and to continue perfection of the
         Security Interest.

                  (b) The Borrower hereby irrevocably consents to any act by
         the Bank or its agents in entering upon any premises during the
         continuance of any Event of Default for the purposes of either 
         (i) inspecting the Collateral or (ii) taking possession of the
         Collateral after any Event of Default in any commercially reasonable
         manner; and the Borrower hereby waives its right to assert against the
         Bank or its agents any claim based upon trespass or any similar cause
         of action for entering upon any premises where the Collateral may be
         located.

                  (c) The Borrower authorizes the Bank to collect and apply
         against the Indebtedness any refund of insurance premiums or any
         insurance proceeds payable on account of the loss or damage to any of
         the Collateral and appoints the Bank as the Borrower's
         attorney-in-fact to endorse any check or draft representing such
         proceeds or refund. Notwithstanding the foregoing, the Borrower shall
         be entitled, upon written request given to the Bank within 30 days of
         any loss or damage to any Equipment, to use all insurance proceeds
         payable as the result of such loss or damage to repair or replace any
         damaged Equipment if. (i) no Event of Default shall have occurred and
         be continuing hereunder as of the date of the payment of such
         insurance proceeds; (ii) the insurance proceeds are paid into an
         escrow account with the Bank; (iii) all repairs or replacements are
         satisfactory to the Bank; and (iv) the proceeds held in escrow are
         disbursed solely to repair or replace the damaged Equipment. The Bank
         shall have a lien on all funds held in the escrow account pursuant to
         the foregoing subparagraph (ii) as further security for the Notes and
         the other Indebtedness secured hereby. In addition, the Bank shall
         have a lien on all repaired equipment and all replacement equipment
         obtained with any such insurance proceeds, and all such equipment
         shall be deemed "Equipment" hereunder. The Borrower shall take all
         such action as the Bank may reasonably request to confirm and perfect
         the Bank's security interest in all such repaired equipment and all
         such replacement equipment.

                                       4
<PAGE>

                  (d) Upon the Borrower's failure to perform any of its duties
         hereunder, the Bank may, but it shall not be obligated to, perform any
         of the duties and the Borrower shall forthwith upon demand reimburse
         the Bank for any expenses incurred by the Bank in so doing.

                  (e) No delay or omission by the Bank in exercising any right
         hereunder or with respect to any Indebtedness shall operate as a
         waiver of that or any other right, and no single or partial exercise
         of any right shall preclude the Bank from any other or further
         exercise of the right or the exercise of any other right or remedy.
         The Bank may cure any Event of Default by the Borrower in any
         reasonable manner without waiving the Event of Default so cured and
         without waiving any other prior or subsequent Event of Default by the
         Borrower. All rights and remedies of the Bank under this Agreement and
         under the Uniform Commercial Code shall be deemed cumulative.

                  (f) The Bank shall exercise reasonable care in the custody
         and preservation of the Collateral to the extent required by law and
         it shall be deemed to have exercised reasonable care if it takes such
         action for that purpose as the Borrower shall reasonably request in
         writing; however, no omission to do any act not requested by the
         Borrower shall be deemed a failure to exercise reasonable care and no
         omission to comply with any requests by the Borrower shall of itself
         be deemed a failure to exercise reasonable care. The Bank shall have
         no obligation to take and the Borrower shall have the sole
         responsibility for taking any steps to preserve rights against all
         prior parties to any instrument or chattel paper in the Bank's
         possession as Collateral or as proceeds of the Collateral. The
         Borrower waives notice of dishonor and protest of any instrument
         constituting Collateral at any time held by the Bank on which the
         Borrower is in any way liable and waives notice of any other action
         taken by the Bank.

                  (g) The Borrower authorizes the Bank without affecting the
         Borrower's obligations hereunder from time to time: (i) to take from
         any party (other than the Borrower) and hold collateral (other than
         the Collateral) for the payment of the Indebtedness or any part
         thereof, and to exchange, enforce or release such collateral or any
         part thereof-, (ii) to accept and hold the endorsement or guaranty of
         payment of the Indebtedness or any part thereof and to release or
         substitute any such endorser or guarantor or any party who has given
         any security interest in any collateral as security for the payment of
         the Indebtedness or any part thereof or any party in any way obligated
         to pay the Indebtedness or any part thereof; and (iii) upon the
         occurrence of any Event of Default to direct the manner of the
         disposition of the Collateral and any other collateral and the
         enforcement of any endorsements or guaranties relating to the
         Indebtedness or any part thereof as the Bank in its sole discretion
         may determine.

                  (h) During the continuance of an Event of Default, the Bank
         may demand, collect and sue for all proceeds (either in the Borrower's
         name or the Bank's name at the Bank's option), with the right to
         enforce, compromise, settle or discharge any proceeds.

                                       5

         The Borrower irrevocably appoints the Bank as the Borrower's
         attorney-in-fact to endorse the Borrower's name on all checks,
         commercial paper and other instruments pertaining to the proceeds
         before or after the occurrence of an Event of Default.

                  (i) The rights and benefits of the Bank under this Agreement
         shall, if the Bank agrees, inure to any party acquiring an interest in
         the Indebtedness or any part thereof

                  (j) The terms "Bank" and "Borrower" as used in this Agreement
         include the heirs, personal representatives and successors or assigns
         of those parties.

                  (k) If more than one Borrower executes this Agreement, the
         term "Borrower" includes each of the Borrowers as well as all of them,
         and their obligations under this Agreement shall be joint and several.

                  (1) This Agreement may not be modified or arif6nded nor shall
         any provision of it be waived except in writing signed by the Borrower
         and by an authorized officer of the Bank.

                  (m) This Agreement shall be construed under the Florida
         Uniform Commercial Code and any other applicable laws in effect from
         time to time.

                  (n) This Agreement is a continuing agreement which shall
         remain in force until the Bank shall actually receive written notice
         of its termination and thereafter until all of the Indebtedness
         contracted for or created before receipt of the notice and any
         extensions or renewals of that Indebtedness (whether made before or
         after receipt of the notice) including without limitation all interest
         thereon both before and after receipt of the notice shall be paid in
         full.

         DATED the day and year first above written.

         (d) Upon the occurrence of an Event of Default hereunder, interest
shall accrue at the Default Rate hereinafter set forth notwithstanding the
provisions of this section.

         4. Prepayment. The Borrower shall be entitled to prepay this Note in
            -----------
whole or in part at any time without penalty. Prepayments of principal made
after the expiration of the Revolving Period shall be applied in the inverse
order of principal payments required hereunder.

         5. Application of Payments. All payments hereunder shall be applied
            ------------------------
first to the Bank's costs and expenses payable under the Loan Agreement or
hereunder, then to- fees authorized hereunder or under the Loan Agreement, then
to interest and then to principal.

         6. Default. Any Event of Default under the Loan Agreement shall be
            --------
considered an "Event of Default" hereunder. If any Default (as defined in the
Loan Agreement) shall occur, any obligation of the Bank to make advances
hereunder shall be terminated without notice to the Borrower. In addition, if
any Event of Default shall occur, the outstanding principal of this Note, all
accrued and unpaid interest hereunder and all other amounts payable under this
Note shall be and become, in the manner and as provided in the Loan Agreement,
forthwith due and payable, without presentment, demand, protest or further
notice of any kind, all of which are hereby expressly waived by the Borrower.
Upon the occurrence of any Event of Default, the outstanding principal of this
Note, and any accrued and unpaid interest, shall bear interest at a rate of
either four percent (40/o) per annum above the Prime Rate after default until
paid or, if such rate is usurious under the laws of Florida, then at the
highest legal rate permissible thereunder (the "Default Rate"). For purposes
hereof, the "Prime Rate" shall mean the rate of interest announced from time to
time by the Bank (or any successor thereto) as its prime rate. The Default Rate
shall change on each day that the Prime Rate changes.

         7. Expenses. The Borrower agrees to pay the Bank all costs incurred by
            ---------
it in connection with the collection of this Note. Such costs include, without
limitation, reasonable fees for the services of counsel and legal assistants
employed to collect this Note, whether or not suit be brought, and whether
incurred in connection with collection, trial, appeal or otherwise. The
Borrower further agrees to indemnify and hold the Bank harmless against
liability for the payment of state documentary stamp taxes, intangible taxes or
other taxes (including interest and penalties, if any), excluding income or
service taxes of the Bank, which may be determined to be payable with respect
to this transaction.

         8. Late Charge. A late charge of five percent (5.0%) of any payment
            ------------
required hereunder shall be imposed on each and every payment not received by
the Bank within ten (10) days after it is due. However, the late charge shall
not in any event exceed $250 with respect to any delinquent installment. The
late charge is not a penalty, but liquidated damages to defray administrative
and related expenses due to such late payment. The late charge shall be


                                       3
<PAGE>

immediately due and payable and shall be paid by the Borrower to the Bank
without notice or demand. This provision for a late charge is not and shall not
be deemed a grace period, and the Bank has no obligation to accept a late
payment. Further, the acceptance of a late payment shall not constitute a
waiver of any default then existing or thereafter arising under this Note.

         9. Setoffs. The Borrower hereby grants to the Bank a continuing first
            --------
lien security interest in any and all money, general or specific deposits, or
property of the Borrower now or hereafter in the possession of the Bank. The
Borrower authorizes and empowers the Bank, in its sole discretion, at any time
after the occurrence of a default hereunder to appropriate and, in such order
as the Bank may elect, apply any such money, deposits or property to the
payment hereof or to the payment of any and all indebtedness, liabilities and
obligations of the Borrower to the Bank or any of the Bank's affiliates,
whether now existing or hereafter created or arising or now owned or howsoever
after acquired by the Bank or any of the Bank's affiliates (whether such
indebtedness, liabilities and obligations are or will be joint or several,
direct or indirect, absolute or contingent, liquidated or unliquidated, matured
or unmatured, including, but not limited to, any letter of credit issued by the
Bank for the account of the Borrower).

         10. Miscellaneous. The Borrower and all sureties, endorsers and
             --------------
guarantors of this Note shall make all payments hereunder in lawful money of
the United States at the Bank's address set forth herein or at such other place
as the Bank may designate in writing. The remedies of the Bank as provided
herein shall be cumulative and concurrent, and may be pursued singly,
successively or together, at the sole discretion of the Bank and may be
exercised as often as occasion therefor shall arise. No act of omission or
commission of the Bank, including specifically any failure to exercise any
right, remedy or recourse, shall be effective, unless set forth in a written
document executed by the Bank, and then only to the extent specifically recited
therein. A waiver or release with reference to one event shall not be construed
as continuing, as a bar to, or as a waiver or release of any subsequent right,
remedy or recourse as to any subsequent event. This Note shall be construed and
enforced in accordance with Florida law and shall be binding on the successors
and assigns of the parties hereto. The term "Bank" as used herein shall mean
NationsBank, N.A. and its successors and permitted assignees under the Loan
Agreement. The Bank may, at its option, round any or all fractional interest
rates under paragraph 3 upwards to the next higher 1/100 of 1%.

         The Borrower hereby: (i) waives demand, notice of demand, presentment
for payment, notice of nonpayment or dishonor, protest, notice of protest and
all other notice, filing of suit and diligence in collecting this Note, or in
the Bank's enforcing any of its rights under any guaranties securing the
repayment hereof; (ii) agrees to any substitution, addition or release of or
any party or person primarily or secondarily liable hereon; (iii) agrees that
the Bank shall not be required first to institute any suit, or to exhaust its
remedies against the Borrower or any other person or party to become liable
hereunder, or against any collateral in order to enforce payment of this Note;
and (iv) agrees that, notwithstanding the occurrence of any of the foregoing
(except with the express written release by the Bank of the Borrower), the
Borrower shall be and remain directly and primarily, liable for all sums due
under this Note.

                  (c) The total liability of the Borrower and any endorsers or
         guarantors hereof for payment of interest shall not exceed any

         laws. If any interest is received or charged by any holder hereof in
         excess of that amount, the Borrower shall be entitled to an immediate
         refund of the excess.

                  (d) Upon the occurrence of an Event of Default hereunder,
         interest shall accrue at the Default Rate hereinafter set forth

accrued and unpaid interest hereunder and all other amounts payable under this
Note shall be and become, in the manner and as provided in the Loan Agreement,
forthwith due and payable, without presentment, demand, protest or further

Upon the occurrence of any Event of Default, the outstanding principal of this
Note, and any accrued and unpaid interest, shall bear interest at a rate of
either four percent (4%) per annum above the Prime Rate after default until
paid or, if such rate is usurious under the laws of Florida, then at the

not in any event exceed $250 with respect to any delinquent installment. The
late charge is not a penalty, but liquidated damages to defray administrative
and related expenses due to such late payment. The late charge shall be
immediately due and payable and shall be paid by the Borrower to the Bank
without notice or demand. This provision for a late charge is not and shall not
be deemed a grace period, and the Bank has no obligation to accept a late
payment. Further, the acceptance of a late payment shall not constitute a
waiver of any default then existing or thereafter arising under this Note.

         9. Setoffs. The Borrower hereby grants to the Bank a continuing first
            --------
lien security interest in any and all money, general or specific deposits, or

and obligations are or will be joint or several, direct or indirect, absolute
or contingent, liquidated or unliquidated, matured or unmatured, including, but
not limited to, any letter of credit issued by the Bank for the account of the
Borrower).

exercised as often as occasion therefor shall arise. No act of omission or
commission of the Bank, including specifically any failure to exercise any
right, remedy or recourse, shall be effective, unless set forth in a written
document executed by the Bank, and then only to the extent specifically recited
therein. A-waiver or release with reference to one event shall not be construed
as continuing, as a bar to, or as a waiver or release of any subsequent right,
remedy or recourse as to any subsequent event. This Note shall be construed and
enforced in accordance with Florida law and shall be binding on the successors

(except with the express written release by the Bank of the Borrower), the
Borrower shall be and remain directly and primarily, liable for all sums due

                      AMENDED AND RESTATED LOAN AGREEMENT
                      -----------------------------------


         THIS AGREEMENT is made this 25th day of November, 1998, between
AMERICAN TECHNICAL CERAMICS CORP. (the "Borrower"), a Delaware corporation, and
NATIONSBANK, N.A. (the "Bank"), successor by merger to Barnett Bank, N.A.

                                    Recitals
                                    --------

         The Borrower wishes to obtain credit from the Bank on the terms and
conditions set forth herein.

         NOW, THEREFORE, for good and valuable consideration, the parties agree
as follows:

                                   ARTICLE I
                             BORROWING AND PAYMENT
                             ---------------------

         1.01     Revolving Credit Advances.
                  --------------------------

                  (a) The Bank hereby establishes in favor of the Borrower a
         revolving line of credit. The Borrower shall be entitled to borrow,
         repay and reborrow funds from the Bank in accordance with the terms
         hereof so long as the total principal amount owed to the Bank under
         the revolving line of credit does not exceed $2,000,000 (or such
         lesser amount as is set forth herein) from the date hereof through the
         end of the Revolving Period (as defined below). The Bank's obligation
         to make advances under this revolving line of credit shall terminate
         on the last day of the Revolving Period or such earlier date as is set
         forth herein. This indebtedness shall be evidenced by a Renewal
         Promissory Note (as amended, extended or renewed from time to time,
         the "Revolving Note") of even date herewith executed by the Borrower
         in favor of the Bank in the original principal amount of $2,000,000.
         The Revolving Note shall bear interest at the rate set forth therein
         and shall be payable as set forth therein.

                  (b) The Bank shall make each advance under the Revolving Note
         upon notice from the Borrower to the Bank specifying the date and
         amount of such advance. The Bank will make each requested advance
         available to the Borrower not later than the close of business on the
         business day following the day of the request by crediting the
         Borrower's account maintained with the Bank in the amount of the
         advance if as of such time: (i) the Bank's obligation to make advances
         hereunder has not terminated or expired; (ii) a Default or Event of
         Default (as hereinafter defined) has not occurred; and (iii) all
         conditions to the advance set forth herein or in any other Loan
         Documents (as hereinafter defined) have been satisfied.

                  (c) For purposes hereof, the "Revolving Period" shall mean a
         period commencing on the date hereof and ending on June 30, 1999.
         Notwithstanding the foregoing, the Revolving Period shall be extended
         on June 30, 1999, and each June 30 thereafter (each such date,
         including June 30, 1999, an "Extension Date") for a one-year period



<PAGE>



         foregoing, the Revolving Period shall be extended on June 30, 1999,
         and each June 30 thereafter (each such date, including June 30, 1999,
         an "Extension Date") for a one-year period commencing on each such
         Extension Date and continuing until the next June 30 thereafter unless
         the Bank in its sole discretion elects not to extend the Revolving
         Period in accordance with the terms hereof. If the Bank elects not to
         extend the Revolving Period, it shall provide written notice of such
         election to the Borrower at least 45 days prior to the next scheduled
         Extension Date. If the Bank provides such notice, then: (i) the
         Revolving Period shall terminate on the next scheduled Extension Date;
         and (ii) the Revolving Period shall not be further extended beyond
         such Extension Date. The Bank's election shall be final and binding,
         and the Bank may elect not to extend the Revolving Period whether or
         not a Default or Event of Default (as defined herein) has occurred.
         The Bank may condition any extension of the Revolving Period on such
         terms as it may deem appropriate.

                  (d) The Borrower shall pay the Bank a facility fee on the
         daily average unused amount of the Revolving Note during the Revolving
         Period at the rate of one-quarter percent (1/4%) per annum (calculated
         on the basis of a 360 day year for the actual number of days elapsed).
         The Borrower shall pay the fee quarterly in arrears within 15 days
         after each October 1, January 1, April 1 and July 1, commencing
         January 1, 1999, and on the termination or expiration of the Revolving
         Period.

         1.02     Equipment Line of Credit.
                  -------------------------

                  (a) The Bank hereby establishes in favor of the Borrower a
          line of credit (the "Equipment Line of Credit") pursuant to which the
          Borrower may obtain advances through September 30, 2000, on a
          revolving basis in accordance with the terms hereof to finance
          equipment (collectively, the "Equipment") purchased by the Borrower
          for use by it in the ordinary course of business. The Borrower may
          borrow, repay and reborrow:funds under the Equipment Line of Credit
          in accordance with the terms hereof for so long as the aggregate
          outstanding principal amount under the Equipment Line of Credit does
          not exceed $3,500,000.00 at any time. The Equipment Line of Credit
          shall be evidenced by the following promissory notes: (i) promissory
          note executed by the Borrower in favor of the Bank in the principal
          amount of $3,500,000.00 (as amended, extended or renewed from time to
          time, the "Sub-Line Note"); and (ii) such other fully amortizing
          notes (as amended, extended or renewed from time to time, the "Term
          Notes") as the balance of the Sub-Line Note may be rolled into from
          time to time in accordance with the terms hereof. The Equipment Line
          of Credit (including, without limitation, all amounts outstanding
          under the Sub-Line Note and the Term Notes) shall be secured by a
          first priority security interest in, and lien upon, all Equipment
          financed with advances thereunder pursuant to a security agreement
          (as amended or restated from time to time, the "Security Agreement")
          substantially in the form attached hereto as Exhibit "A".

                  (b) For so long as no Default or Event of Default has
         occurred hereunder, the Borrower may obtain advances (each, an
         "Advance") from the Bank under the Sub-Line Note so long as the
         outstanding principal balance thereunder does not at any time exceed
         $3,500,000.00 (or such lesser amount as is set forth herein). In no
         event shall the amount of any Advance under the Sub-Line Note exceed
         the 100% of the Borrower's cost of the Equipment to be financed with
         such Advance. The Borrower shall deliver a request (each, a "Request")
         for each Advance to the Bank together with such documents as the Bank
         may from time to time request, including, without limitation, each of
         the following:

                           (i)  The invoice or other contract relating to the 
                  Borrower's  purchase of the Equipment to be financed 
                  therewith;

                           (ii) A certificate of title for any motor vehicle to
                  be financed with the Advance (or, at the Bank's option, such
                  other evidence of title as the Bank may request);

                           (iii) Evidence satisfactory to the Bank that the
                   Borrower owns good and marketable title to the Equipment to
                   be financed free and clear of all liens, claims and
                   encumbrances;

                           (iv) If requested by the Bank, UCC financing
                   statements, assignments of title and such other security
                   documents as the Bank may require in form satisfactory to
                   the Bank for all appropriate jurisdictions showing the Bank
                   as secured party and the Borrower as debtor and encumbering:
                   (aa) the Equipment to be financed with the Advance; and (bb)
                   all proceeds thereof; and

                           (v) Such other instruments or documents as the Bank
                   shall reasonably require.

                  (c) Not later than three business days after the Bank's
         receipt of the items described in the foregoing subparagraph (b), the
         Bank will make the requested Advance available to the Borrower by
         crediting an account of the Borrower maintained with the Bank in the
         amount of the Advance if as of such time: (i) the Bank's obligation to
         make Advances hereunder has not terminated or expired; (ii) a Default
         or Event of Default (as hereinafter defined) has not occurred; and
         (iii) all conditions to the Advance set forth herein or in any other
         Loan Documents (as hereinafter defined) have been satisfied.

                  (d) For so long as no Default or Event of Default has
         occurred, the outstanding principal balance of the Sub-Line Note shall
         be rolled over into a fully amortizing Term Note every six months or,
         if sooner, when the outstanding principal balance of the Sub-Line Note
         reaches $3,500,000.00. If any Default or Event of Default has occurred
         under this Agreement, the Sub-Line Note shall not be rolled into a
         Term Note but shall instead be fully due and payable in accordance
         with the terms hereof. At the time that any amount is rolled


                                       3
<PAGE>



         from the Sub-Line Note into a Term Note, all accrued and unpaid
         interest under the Sub-Line Note shall be paid and brought current. In
         no event shall the total combined principal amount outstanding under
         the Sub-Line Note and the Term Notes, or otherwise owed under the
         Equipment Line of Credit, exceed $3,500,000.00.

                  (e) The Term Notes shall be subject to the following terms
         and conditions:

                           (i) Each Term Note shall provide for: (aa) payment
                  of all accrued interest on a quarterly basis commencing three
                  months from the date of the Term Note; and (bb) payment of
                  principal in quarterly installments commencing three months
                  from the date of the Term Note. Each such principal
                  installment shall equal an amount sufficient to fully
                  amortize the original principal amount of the Term Note in
                  equal quarterly installments over the term of the Term Note.
                  The Borrower shall pay the remaining outstanding principal
                  amount of each Term Note, if any, at the expiration of the
                  ten-n thereof. The term of each Term Note shall be determined
                  by mutual consent of the parties prior to the execution of
                  the Term Note (but in no event, however, shall the term of
                  any Term Note be less than four years or more than seven
                  years).

                           (ii) Interest shall initially accrue on the
                  outstanding principal balance of each Term Note at a rate
                  that is equal to the Adjusted Libor Rate (as defined herein)
                  in effect as of the date of the Term Note. The rate of
                  interest shall be adjusted on each Interest Rate Adjustment
                  Date (as defined herein) so that interest shall accrue at the
                  Adjusted Libor Rate for the Interest Period (as defined
                  herein) commencing on such Interest Rate Adjustment Date. For
                  purposes of this paragraph, the following terms shall have
                  the following meanings:

                                    (aa) "Adjusted Libor Rate" for each
                           Interest Period shall mean a rate that is equal to
                           the applicable Libor Rate plus 2.0% per annum. The
                           Libor Rate for each Interest Period shall mean the
                           offered rate for deposits in United States dollars
                           in the London Interbank market for a three month
                           period which appears on the Libor Rate Reference
                           Page (as defined herein) as of 11:00 a.m. (London

                           Day (as defined herein) of the Interest Period. If
                           at least two such offered rates appear on the Libor
                           Rate Reference Page, the rate will be the arithmetic
                           mean of such offered rates. The Bank may, in its
                           discretion, use rate quotations for a 90 day period
                           in lieu of quotations for a substantially equivalent
                           three month period.

                                    (bb) "Banking Business Day" shall mean each
                           day other than a Saturday, a Sunday or any holiday
                           on which commercial banks in Jacksonville, Florida
                           are closed for business.

         basis be able to perform properly date sensitive functions before, on
         and after January 1, 2000, except to the extent that a failure to do
         so could not reasonably be expected to have a material adverse effect
         on the business, operations, creditworthiness or financial condition
         of the Borrower or any related entity. For purposes hereof, the
         following terms shall have the following meanings: (i) "Related

the financial statements already delivered to the Bank, no loss, damage,
destruction or taking of any of the physical properties of the Borrower which
are material to its business has occurred which has not been fully restored or
replaced, or which is not fully covered by insurance, and neither such property
nor business has been adversely affected in any substantial way as the result
of any accident, strike, lockout, combination of workmen, embargo, riot, war,
act of God or public enemy.

         5.06 Corporate Restrictions. The Borrower is not a party to any
              -----------------------
contract or subject to any charter or other corporate restriction which would
materially and adversely affect its property or business, or its ability to
perform its obligations under the Loan Documents.

         5.07 Taxes. The Borrower has filed all federal and state tax returns
              ------
which are required to be filed, and has paid all taxes as shown on the returns
and on all assessments received by it to the extent that the taxes have become
due. Proper and accurate amounts have been withheld by the Borrower from its
employees for all periods in material compliance with the tax, social security
and unemployment withholding provisions of applicable federal, state, local and
foreign law and such withholdings have been timely paid to the respective
governmental agencies.

         5.08 Default. There exists as of the date hereof no Default or Event
              --------
of Default.

         5.09 Other Representations. All warranties and representations of the
              ----------------------
Borrower contained in any of the other Loan Documents are true and accurate in
all material respects.

         5.10 ERISA. No Plan has incurred any material accumulated funding
              ------
deficiency within the meaning of the Employee Retirement Income Security Act of
1974, and the Borrower has not incurred any material liability to the Pension
Benefit Guaranty Corporation (or any successor) in connection with any Plan.

         5.11 Purpose of the Borrower. None of the proceeds of the loan by the
              ------------------------
Bank to the Borrower made hereunder will be used for the purpose of purchasing
or carrying any "margin security" within the meaning of Regulation U (12 CFR
Part 221) of the Board of Governors of the Federal Reserve System or for the
purpose of reducing or retiring any indebtedness which was originally incurred
to purchase or carry a margin security or for any other purpose which might
constitute this transaction a "purpose credit" within the meaning of Regulation
U, as now in effect or as it may hereafter be amended. Neither the Borrower nor
any agent acting on its behalf has taken or will take any action which might
cause this Agreement or any Loan Document to violate Regulation U or any other
regulation of the Board of Governors of the Federal Reserve System or to
violate the Securities Exchange Act of 1934, in each case as in effect now or
as the same may hereafter be amended.

         5.12 Payment of Loan Proceeds. The Bank is authorized to disburse all
              -------------------------
proceeds of any loan to the Borrower hereunder directly to or upon the order of
the President of the Borrower without looking into the use of those proceeds.
The President of the Borrower as of the date hereof is Victor Insetta. The Bank
may rely on the fact that he continues to serve in that capacity until the Bank
receives written notice to the contrary.

         5.13 Solvency. After giving effect to the full funding of the loan
              ---------
contemplated herein, the Borrower is solvent. "Solvent" shall mean, when used
with respect to any person or entity, that: (a) such person or entity does not
intend to incur, and does not believe and has no reason to believe that it will
incur, debts beyond its ability to pay as they become due; (b) the sum of such
person's or entity's assets is greater than all of such person's or entity's
liabilities at a fair valuation; (c) such person or entity has sufficient means
to enable it to pay its debts as they become due; and (d) such person or entity
does not have unreasonably small capital to carry on such person's or entity's
business as theretofore operated and all businesses in which such person or
entity is about to engage. "Fair valuation" is intended to mean that value
which can be obtained if the assets are sold within a reasonable time in
arm's-length transactions in an existing and not theoretical market.

         6.01 Events of Default. Each of the following events shall constitute
              ------------------
an "Event of Default" hereunder:

                  (a) if the Borrower defaults in the payment of any principal,
         interest or other amount under any Note when the same shall become
         due, either by the terms thereof or otherwise as provided herein, and
         such default continues for ten calendar days; or

                  (b) if there occurred an Event of Default under and as
         defined in that certain Loan Agreement, dated as of September 27,
         1994, between the Borrower and the Bank, as amended from time to time
         (the "Term Loan Agreement"); or

                  (c) if the Borrower defaults: (i) in any payment of principal
         of or interest on any other material obligation beyond any period of
         grace provided with respect thereto, or (ii) in the performance or
         observance of any other agreement, term, or condition contained in any
         agreement under which any such obligation is created if the effect of
         such default is to cause, or permit the holder or holders of such
         obligation (or trustee on behalf of such holder or holders) to cause,
         such obligation to become due prior to its stated maturity, except for
         obligations disputed in good faith if the Bank is promptly notified
         thereof and, if requested by the Bank, funded reserves are established
         in amounts which in the Bank's opinion are sufficient to pay the total
         amount in dispute; or

                  (d) if any statement, representation or warranty made by the
         Borrower herein or in any writing now or hereafter furnished in
         connection with or pursuant to the Loan


                                      15
<PAGE>

         Documents or in connection with any audit shall be false in any
         material respect; or if the Borrower omits or fails to disclose
         immediately any substantial contingent or liquidated liabilities, or
         any material adverse change in facts previously disclosed by any
         statement, representation, certificate or warranty to the Bank; or

                  (e) if there occurs a breach of Section 4.01 hereof; or

                  (f) if the Borrower makes an assignment for the benefit of
         creditors or is generally not paying its debts as they become due; or

                  (g) if any order, judgment or decree is entered under the
         bankruptcy, reorganization, compromise, arrangement, insolvency,
         readjustment of debt, dissolution or liquidation or similar law of any
         jurisdiction adjudicating the Borrower bankrupt or insolvent; or

                  (h) if the Borrower petitions or applies to any tribunal for,
         or consents to, the appointment of a trustee, receiver, custodian,

         or moratorium law of any other jurisdiction, whether now or hereafter
         in effect; or

                  (i) if any such petition or application is filed, or any such
         proceedings are commenced against the Borrower and if the Borrower by
         any act indicates its approval thereof, consent thereto, or
         acquiescence therein, or an order is entered in an involuntary case
         under the Bankruptcy Code of the United States, or an order, judgment
         or decree is entered appointing any such trustee, receiver, custodian,

         Borrower decreeing the dissolution or split-up of the Borrower; or

                  (k) if the Borrower defaults in the performance or observance
         of any other material agreement, covenant, term or condition contained
         herein or in any other Loan Document and such default shall not have
         been remedied within 30 days after written notice thereof is sent by
         the Bank to the Borrower except, however, that an Event of Default
         shall not be deemed to have occurred if the Borrower commences to cure
         such default within such 30-day period and the Borrower completes such
         cure within 60 days after such notice.

         6.02 Default. A "Default" shall be deemed to have occurred hereunder
              --------
if. (i) any event or condition occurs which would constitute an Event of
Default hereunder upon the satisfaction of

<PAGE>

any requirement for notice or passage of time in connection with such event or
condition; or (ii) a "Default" occurs under and as defined in the Term Loan
Agreement.

         6.03 Remedies. If any Default shall occur, any obligation of the Bank
              ---------
to make advances hereunder or under any Loan Document shall be terminated
without notice to the Borrower. In addition, if any Event of Default shall
occur, the Bank may by notice to the Borrower, effective upon dispatch, declare
the entire unpaid principal amount then outstanding under the Loan Documents,
all interest accrued and unpaid under the Loan Documents and all other
indebtedness of the Borrower to the Bank under this Agreement or any of the
other Loan Documents to be forthwith due and payable. Thereupon, the then
outstanding principal amount under the Loan Documents, all such accrued
interest and all such other indebtedness shall become and be forthwith due and
payable, without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Borrower, and the Bank may
immediately enforce payment of all such amounts and exercise any or all of the
rights and remedies of the Bank under this Agreement and other Loan Documents.

         6.04 Termination of Rights to Advances, Automatic Acceleration.
              ----------------------------------------------------------
Notwithstanding anything herein to the contrary, (a) the Borrower's right, if
any, to obtain any additional advances under the Loan Documents shall
automatically terminate upon the initiation against the Borrower of any
proceeding under the Federal Bankruptcy Code, or upon the occurrence of any
Event of Default described in subparagraphs (f), (g), (h) or (i) of Section
6.01, and (b) all indebtedness of the Borrower to the Bank under this Agreement
or any of the Loan Documents shall automatically be and become immediately due
and payable upon the occurrence of any Event of Default described in
subparagraphs (f), (g) or (h) of Section 6.01.

                                  ARTICLE VII
                                 MISCELLANEOUS
                                 -------------

         7.01 Expenses. The Borrower agrees, whether or not the transactions
              ---------
hereby contemplated shall be consummated, to pay, and save the Bank harmless
against liability for the payment of expenses arising in connection with any
renewals or modifications relating hereto and any state documentary stamp taxes
or other taxes (including interest and penalties, if any) which may be
determined to be payable in respect to the execution and delivery of any Loan
Documents executed in connection with this Agreement or any such renewal or
modification. The Borrower acknowledges that it has participated with the Bank
in establishing the structure of this transaction and that it has independently
determined the amount of documentary stamp and other taxes due in connection
herewith. The Borrower has not relied upon representations of the Bank or its
counsel in calculating the amount of such taxes, and the Borrower shall be
liable for any additional taxes (including interest and penalties) which may be
due in connection with this transaction or any renewals hereof. If an Event of
Default shall occur, the Borrower shall also pay all of the Bank's costs of
collection including court costs and the reasonable fees of attorneys and legal
assistants (whether incurred in connection with trial or appellate
proceedings).

         7.02 Survival of Representations and Warranties. All representations
              -------------------------------------------
and warranties contained herein or made in writing by the Borrower in
connection herewith shall survive the execution and delivery of the Loan
Documents but shall expire upon full and indefeasible repayment of all
principal and interest under the Notes.

         7.03 Successors and Assigns. All covenants and agreements in this
              -----------------------
Agreement contained by or on behalf of any of the parties hereto shall bind and
inure to the benefit of the respective successors and assigns of the parties
hereto whether so expressed or not. The Borrower shall not be entitled to
assign its rights hereunder. The Bank may not, without the Borrower's consent,
grant participations in the Loan Documents other than to affiliates of the Bank
(or successors in merger) regularly engaged in the business of making loans
similar to the loan made to the Borrower pursuant to the Loan Documents. The
Bank may disclose to any such participant such information concerning the
Borrower as the Bank deems appropriate.

         7.04 Notices. All communications, notices or demands provided for
              --------
hereunder or under any other Loan Document to which the Borrower is a party
shall be sent by first class mail, by courier, by hand, or by certified mail as
follows or to such other address with respect to any party as such party shall
notify the others in writing:

         To the Bank:       NationsBank, N.A.
                            50 N. Laura Street
                            Jacksonville, Florida 32202

                            Huntington Station, New York 11746
                            Attn:  Kathleen M. Kelly, Vice President,
                                   Administration

Except as otherwise specifically set forth herein, each such communication,
notice or demand shall be deemed given: (i) on the third business day after
deposited in the mail with proper postage affixed if sent by mail; and 
(ii) when actually delivered to the appropriate address if sent by courier or
by hand.

         7.05 Applicable Law, Etc. This Agreement shall be construed and
              --------------------
enforced in accordance with the laws of the State of Florida. The descriptive
section headings herein have been inserted for convenience only and shall not
be deemed to limit or otherwise affect the construction of any provisions
hereof This Agreement may be executed simultaneously in several counterparts.
Each counterpart shall be deemed an original. All rights and remedies of the
Bank hereunder are cumulative and in addition to any rights and remedies which
the Bank may have under the laws of Florida. The Bank's exercise of any one
right or remedy against one party hereto will not deprive the Bank of any right
or remedy against that party or any other parties hereto. No right, power or

                                      18
<PAGE>

remedy conferred upon or reserved to the Bank under this Agreement or any other
of the Loan Documents is exclusive of any other right, power or remedy in any
of the Loan Documents, but each and every such right, power and remedy shall be
cumulative and concurrent and shall be in addition to any other right, power
and remedy given hereunder or under any other Loan Documents, or now or
hereafter existing at law, in equity or by statute. No delay or omission of the
Bank to exercise any right, power or remedy under any of the Loan Documents or
accruing upon any Event of Default shall exhaust or impair any such right,
power or remedy or shall be construed to waive any such Event of Default or to
constitute acquiescence therein. Every right, power and remedy given to the
Bank under any of the Loan Documents may be exercised from time to time and as
often as may be deemed expedient by the Bank. No waiver of any Default or Event
of Default hereunder shall extend to or affect any subsequent Default or Event
of Default or any other Default or Event of Default then existing, or impair
any rights, powers or remedies consequent thereon. No term of any Loan Document
may be changed, waived, discharged or terminated orally, or by any action or
inaction, but only by an instrument in writing signed by the party against
which enforcement of the change, waiver, discharge or termination is sought. If
any portion of any Loan Document is declared void by any court as illegal or
against public policy, the remainder of the Loan Documents in question shall
continue in full effect. Upon receipt by the Borrower of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Note
(the "Lost Note") and of an indemnity agreement reasonably satisfactory to the
Borrower, the Borrower will make and deliver to the Bank a new Note of like
tenor, date and principal amount in lieu of the Lost Note.

         7.06 Survival of Obligations Upon Termination of Financing
              -----------------------------------------------------
Arrangement. Except as otherwise expressly provided for in the Loan Documents,
------------
no termination or cancellation (regardless of cause or procedure) of the
financing under this Agreement shall in any way affect or impair the
obligations, duties, and liabilities of the Borrower or the rights of the Bank
relating to any transaction or event occurring prior to such termination. This
Agreement supersedes and replaces any commitment letter relating to the loan
extended to the Borrower pursuant to the Loan Documents.

         7.07 Amended and Restated Agreement. This Agreement amends and
              -------------------------------
restates that certain Loan Agreement dated September 26, 1996, by and between
the Borrower and the Bank.

         7.08 Arbitration.  The parties agree to the following arbitration 
              ------------
provisions:

                  (a) ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES
         HERETO, INCLUDING, BUT NOT LIMITED TO, THOSE ARISING OUT OF OR
         RELATING TO THIS AGREEMENT OR ANY LOAN DOCUMENT OR OTHER INSTRUMENTS,

         APPLIES IN ANY COURT HAVING JURISDICTION OVER SUCH ACTION.

         ARBITRATOR. IF JAMS/ENDISPUTE IS UNABLE OR LEGALLY PRECLUDED FROM

                            TAX INDEMNITY AGREEMENT

         This Agreement is made this 25th day of November, 1998, by and between
AMERICAN TECHNICAL CERAMICS CORP. (the "Borrower") and NATIONSBANK, N.A. (the
"Bank").

                                    Recitals
                                    --------

         The Bank and the Borrower are executing an Amended and Restated Loan
Agreement (as amended or restated from time to time, the "Loan Agreement") of
even date herewith. The Borrower may, pursuant to the Loan Agreement, execute
and deliver the Notes (as defined in the Loan Agreement). The Loan Agreement
and the Notes, together with all other Loan Documents (as defined in the Loan
Agreement) are collectively referred to herein as the "Credit Documents". The
Borrower has indicated that the Credit Documents are exempt from Florida
documentary stamp taxes (collectively, the "Taxes"). The Borrower is executing
this Agreement to induce the Bank to accept the Credit Documents without
payment of such taxes.

         NOW THEREFORE, for good and valuable consideration, the parties agree
as follows:

Borrower of notice of the assertion of such demand, assertion, claim, action or
proceeding; and (b) the Borrower shall pay all costs and expenses of such

                          AMENDMENT TO LOAN AGREEMENT
                          ---------------------------


         THIS AMENDMENT is made this 4th day of February, 1999, by and between
AMERICAN TECHNICAL CERAMICS CORP. (the "Borrower"), a Delaware corporation, and
NATIONSBANK, N.A. (the "Bank"), successor by merger to Barnett Bank, N.A.

                                    Recitals

         The Borrower and the Bank entered into a Loan Agreement (as amended
from time to time, the "Loan Agreement") dated November 25, 1998, pursuant to
which the Bank has provided a credit facility to the Borrower. The parties wish
to amend the Loan Agreement in accordance with the terms hereof.

         NOW, THEREFORE, for good and valuable consideration, the parties agree
as follows:

         1. Subparagraph (c) of Section 1.01 of the Loan Agreement is hereby
amended so that, from and after the date hereof, such subparagraph shall read
as follows:

                  (c) For purposes hereof, the "Revolving Period" shall mean a
         period commencing on the date hereof and ending on June 30, 1999.
         Notwithstanding the foregoing, the Revolving Period shall be extended
         on June 30, 1999, and each June 30 thereafter through June 30, 2001
         (each such date, including June 30, 1999, and "Extension Date") for a
         one-year period commencing on each such Extension Date and continuing
         until the next june 30 thereafter unless the Bank in its sole
         discretion elects not to extend the Revolving Period in accordance
         with the terms hereof. If the Bank elects not to extend the Revolving
         Period, it shall provide written notice of such election to the
         Borrower at least 45 days prior to the next scheduled Extension Date.
         If the Bank provides such notice, then: (i) the Revolving Period shall
         terminate on the next scheduled Extension Date; and (ii) the Revolving
         Period shall not be further extended beyond such Extension date. The
         bank's election shall be final and binding, and the Bank may elect not
         to extend the Revolving Period whether or not a Default or Event of
         Default (as defined herein) has occurred. The bank may condition any
         extension of the Revolving Period on such terms as it may deem
         appropriate. Notwithstanding any contrary provision set forth herein,
         the Revolving Period shall not in any event extend beyond June 30,
         2002.

         2. The parties acknowledge that the Revolving Note and the Sub-Line
Note (as such terms are defined in the Loan Agreement) include a definition of
the term "Libor Rate Reference Page". Notwithstanding any contrary provision
set forth in such Notes, the parties agree that the term "Libor Rate Reference
Page", as used in such Notes, shall have the meaning set forth in Section
1.02(e)(ii) of the Loan Agreement. The last sentence of Section 3(a)(i) of the
Revolving Note and Section 3(a)(i) of the Sub-Line Note is hereby deleted from
each such Note.

         3. The Loan Agreement shall continue in full force and effect except
as modified herein.
