                                      NOTE

$1,000,000.00     Los Angeles, California,               September 6, 1995

On October 1, 2000, and as hereinafter provided, for value received, the
undersigned promises to pay to IMPERIAL BANK ("Bank"), a California banking
corporation, or order at its Los Angeles Regional office, the principal sum of
$1,000,000.00 or such sums up to the maximum if so stated, as the Bank may now
or hereafter advance to or for the benefit of the undersigned in accordance with
the terms hereof, together with interest from date of disbursement or N/A ,
whichever is later, on the unpaid principal balance ____ at the rate of ___% per
year X at the rate of 1.250% per year in excess of the rate of interest which
Bank has announced as its prime lending rate (the "Prime Rate"), which shall
vary concurrently with any change in such Prime Rate, or $250.00, whichever is
greater. Interest shall be computed at the above rate on the basis of the actual
number of days during which the principal balance is outstanding, divided by
360, which shall, for interest computation purposes, be considered one year.

Interest shall be payable _X_ monthly __ quarterly __ included with principal
_X_ in addition to principal, beginning November 1, 1995, and if not so paid
shall become a part of the principal. All payments shall be applied first to
interest, and the remainder, if any, on principal, __X__ (if checked), Principal
shall be payable in installments of $16,667.00, or more, each installment on the
1st day of each month, beginning November 1, 1995. Advances not to exceed any
unpaid balance owing at any one time equal to the maximum amount specified
above, may be made at the option of Bank.

         Any partial prepayment shall be applied to the installments, if any, in
inverse order of maturity. Should default be made in the payment of principal or
interest when due, or in the performance or observance, when due, of any item,
covenant or condition of any deed of trust, security agreement or other
agreement (including amendments or extensions thereof) securing or pertaining to
this note, at the option of the holder hereof and without notice or demand, the
entire balance of principal and accrued interest then remaining unpaid shall (a)
become immediately due and payable, and (b) thereafter bear interest, until paid
in full, at the increased rate of 5% per year in excess of the rate provided for
above, as it may vary from time to time.

         Defaults shall include, but not be limited to, the failure of the maker
(a) to pay principal or interest when due; the filing as to each person
obligated hereon, whether as maker, co-maker, endorser or guarantor
(individually or collectively referred to as the "Obligor") of a voluntary or
involuntary petition under the provisions of the Federal Bankruptcy Act; the
Issuance of any attachment or execution against any asset of any Obligor; the
death of any Obligor; or any deterioration of the financial condition of any
Obligor which results in the holder hereof considering itself, in good faith,
insecure.

         If any installment payment or principal balance payment due hereunder
is delinquent ten or more days, Obligor agrees to pay a late charge in the
amount of 5% of the payment so due and unpaid. In addition to the payment; but
nothing in this paragraph is to be construed as any obligation on the part of
the holder of this note to accept payment of any installment past due or less
than the total unpaid principal balance after maturity.

         If this note is not paid when due, each Obligor promises to pay all
costs and expenses of collection and reasonable attorney's fees incurred by the
holder hereof on account of such collection, plus interest at the rate
applicable to principal, whether or not suit is filed hereon. Each Obligor shall
be jointly and severally liable hereon and consents to renewals, replacements
and extensions of time for payment hereof, before, at, or after maturity;
consents to the acceptance, release or substitution of security for this note;
and waives demand and protest and the right to assert any statute of
limitations. Any married person who signs this note agrees that recourse may be
had against separate property for any obligations hereunder. The indebtedness
evidenced hereby shall be payable in lawful money of the United States. In any
action brought under or arising out of this note, each Obligor, including
successor(s) or assign(s) hereby consents to the application of California law,
to the jurisdiction of any competent court within the State of California, and
to service of process by any means authorized by California law.

         No single or partial exercise of any power hereunder, or under any deed
of trust, security agreement or other agreement in connection herewith shall
preclude other or further exercises thereof or the exercise of any other such
power. The holder hereof shall at all times have the right to proceed against
any portion of the security for this note in such order and in such manner as
such holder may consider appropriate, without waiving any rights with respect to
any of the security. Any delay or omission on the part of the holder hereof in
exercising any right hereunder, or under any deed of trust, security agreement
or other agreement, shall not operate as a waiver of such right, or of any other
right, under this note or any deed of trust, security agreement or other
agreement in connection herewith.

This Note is being executed together with that certain Credit Agreement, dated
September 6, 1995 between the Borrower and the Bank (the "Credit Agreement"). To
the extent the terms of this Note and the terms of the Credit Agreement are
inconsistent, the terms of the Credit Agreement shall govern.

                                CREDIT AGREEMENT



This Credit Agreement (the " Agreement") is made and entered into on September
6, 1995 by and between XCEL Arnold Circuits, Inc. a New Jersey corporation,
("Borrower") and Imperial Bank, a California banking corporation ("Bank").

         Borrower wishes to secure certain credit accommodations from Bank and
Bank is willing to provide credit accommodations all as provided in this
Agreement.

         In consideration of mutual covenants and conditions hereof, the parties
hereto agree as follows:

1.       AMOUNT AND TERMS OF CREDIT


1.01     TOTAL COMMITMENT. Subject to the terms and conditions of this 
Agreement, Bank shall make available to Borrower from time to time during the
term of this Agreement the credit facilities specified herein up to the
aggregate principal amount of Two Million ($2,000,000) Dollars (the "Total
Commitment"). The Total Commitment shall be comprised of (a) a revolving credit
commitment (the "Revolving Credit Commitment") as provided in Section 1.02
hereof, and (b) a term loan (the "Term Loan") as provided in Section 1.03
hereof.

1.02     REVOLVING CREDIT COMMITMENT. Subject to the terms and conditions of 
this Agreement, between the date of this Agreement and January 15, 1997 (the
"Revolving Commitment Termination Date"), provided that no event of default then
has occurred and is continuing, Bank will provide the Revolving Credit
Commitment of One Million Dollars ($1,000,000) for (a) loans for general working
capital purposes, and (b) the issuance of Sight, Usance, or Standby Letters of
Credit ("Letters of Credit"), provided, however, that the aggregate of the
Letters of Credit, and Revolving Loans at any one time shall not exceed the
Revolving Credit Commitment. No Letter of Credit shall expire after the
Revolving Commitment Termination Date.

AVAILABILITY. Notwithstanding the above, advances and letters of credit issued
under Bank's Revolving Credit Commitment will not exceed 80% of Eligible
Accounts Receivable. Eligible Accounts means all of Borrower's Accounts
excluding, however, (1) all Accounts under which payment is not received within
90 days from any invoice date, (2) all Accounts against which the account debtor
or any other person obligated to make payment thereon 
   3
asserts any defense, offset, counterclaim or other right to avoid or reduce the
liability represented by the Account, (3) any Accounts if the account debtor or
any other person liable in connection therewith is insolvent, subject to
bankruptcy or receivership proceedings or has made an assignment for the benefit
of creditors or whose credit standing is unacceptable to Bank and Bank has so
notified Borrower, (4) any accounts with respect to which 25% or more of the
account debtor's total accounts or obligations outstanding to Borrower are more
than 90 days from invoice date, (5) for accounts (excluding Motorola)
representing more than 20% of total accounts receivable, the balance in excess
of the 20% is not eligible, (6) salesmen's accounts for promotional purposes,
(7) accounts with respect to international transactions unless insured by an
insurance company acceptable to Bank or covered by letters of credit or
confirmed by a bank acceptable to Bank, (8) credit balances greater than 90 days
from invoice date, (9) government receivables, unless specifically assigned to
Bank, and (10) accounts with respect to which the account debtor is an officer,
director, shareholder, employee, subsidiary, or affiliate of Borrower. Eligible
Accounts shall only include such accounts as Bank in its sole discretion shall
determine are eligible from time to time.

1.03     TERM LOAN. Bank will make a Term Loan to Borrower in the amount of One
Million Dollars ($1,000,000), which is subject to the terms and conditions of
this Agreement. Borrower's obligation to repay the principal amount of the Term
Loan, together with accrued interest thereon, is evidenced by a promissory note
issued by Borrower in favor of Bank on the standard form used by Bank to
evidence its commercial loans. The Term Loan provides for payment of principal
in sixty (60) consecutive monthly installments, each in an amount equal to
Sixteen Thousand Six Hundred Sixty Six Dollars ($16, 666.00), commencing on
November 1, 1995, until October 1, 2000 (the "Term Loan Maturity Date"), on
which date all unpaid principal and accrued interest on the Term Loan shall be
due and payable.


2.       COLLATERAL

2.01     SECURITY PROVIDED BY BORROWER. To secure the payment and performance of
all obligations of Borrower to Bank, Borrower shall have granted a first

equipment, furniture and fixtures, now owned or hereafter acquired by Borrower,
