FOR VALUE RECEIVED, M-TRON INDUSTRIES, INC., a Delaware corporation and PIEZO
TECHNOLOGY, INC., a Florida corporation, jointly and severally (sometimes
hereinafter collectively, referred to as the "undersigned" or the "Borrower"),
promise to pay to the order of JPMORGAN CHASE BANK, N.A., or any subsequent
holder of this Note ("Lender") at its principal offices located at 450 South
Orange Avenue, 10th Floor, Orlando, FL 32801 (or at such other place or places
as Lender may designate) the principal sum of One Million Five Hundred Thousand
and No/100 Dollars ($1,500,000.00) or so much thereof as may be from time to
time outstanding, plus interest thereon at the Interest Rate hereinafter
defined, all in accordance with the terms and conditions of this Promissory Note
(this "Note") and Master Loan Agreement dated June 30, 2011(as amended, "Loan
Agreement").
Borrower shall, in accordance with the terms and conditions of the Loan
Agreement be permitted to draw funds (a "Loan Disbursement").  This Note
evidences the Borrower's agreement to repay funds drawn hereunder.  Lender's
records of the aggregate amount of Loan Disbursements from time to time shall be
conclusive proof thereof absent manifest error.
This Note is secured by a Master Security Agreement dated June 30, 2011 granted
by the Borrower in favor of Lender (the "Collateral Document"),  the Loan
Agreement and UCC Financing Statements (the "Financing Statements"), and other
agreements by and between Borrower and Lender.
This Note, the Collateral Document, Loan Agreement, Financing Statements and
such other agreements are hereinafter referred to collectively as the "Loan
Documents" and the loan evidenced thereby is hereinafter referred to as the
"Loan."  Terms used herein but not otherwise defined hereunder are defined as
set forth in the Loan Agreement.  All of the terms, definitions, conditions and
covenants of the Loan Documents are expressly made a part of this Note by
reference in the same manner and with the same effect as if set forth herein at
length, and any holder of this Note is entitled to the benefits of and remedies
provided in the Loan Documents.
Subject to the terms and conditions of the Loan Documents, Lender shall loan
hereunder to Borrower such amounts as may from time to time be requested by
Borrower provided that (a) the aggregate principal amount borrowed hereunder
shall not at any time exceed the full amount of this Note and (b) no Event of
Default, as defined herein, shall exist or be caused thereby. Borrower may, in
accordance with the terms, conditions and limitations of the Loan Agreement,
borrow, repay and reborrow hereunder at any time, up to the full amount of this
Note.  Borrower shall not be permitted to borrow additional advances hereunder
if Borrower is in default under any provision of this Note, any document
evidencing and/or securing this Note, the Loan Agreement, or any other
obligation of Borrower to Lender.  Lender shall have no liability to Borrower
for its refusal to advance funds based upon its determination that any
conditions of such further advances have not been met. Principal of and accrued
interest on Loan Disbursements shall be due and payable as follows:
Interest Rate.  A floating rate of interest equal to CB Floating Rate plus
0.00%.

"CB Floating Rate" means the Prime Rate; provided that the CB Floating Rate
shall, on any day, not be less than the Adjusted One Month LIBOR Rate. The CB
Floating Rate is a variable rate and any change in the CB Floating Rate due to
any change in the Prime Rate or the Adjusted One Month LIBOR Rate is effective
from and including the effective date of such change in the Prime Rate or the
Adjusted One Month LIBOR Rate, respectively.

"Adjusted One Month LIBOR Rate" means, for any day, the sum of (i) 2.50% per
annum plus (ii) the quotient of (a) the interest rate determined by the Lender
by reference to the Page to be the rate at approximately 11:00 a.m. London time,
on such date or, if such date is not a Business Day, on the immediately
preceding Business Day for dollar deposits with a maturity equal to one (1)
month, divided by (b) one minus the Reserve Requirement (expressed as a decimal)
applicable to dollar deposits in the London interbank market with a maturity
equal to one (1) month.

"Prime Rate" means the rate of interest per annum announced from time to time by
the Lender as its prime rate. The Prime Rate is a variable rate and each change
in the Prime Rate is effective from and including the date the change is
announced as being effective. THE PRIME RATE IS A REFERENCE RATE AND MAY NOT BE
THE LENDER'S LOWEST RATE.

1.           Interest will accrue on any non-banking day at the rate in effect
on the immediately preceding banking day.  Interest shall be computed the basis
of the actual number of days elapsed in a year of 360 days.
 
2.            Terms of Repayment: All payments of principal and interest shall
be made in lawful currency of the United States of America which shall be legal
tender in payment of all debts, public and private, at the time of payment.
 
(a)            Interest Only Payments. Interest only payments shall be due and
payable monthly on the fifth (5th) day of each month commencing on October 5,
2012 and continuing on the fifth day of each and every month thereafter until
the Maturity Date, at which time the entire outstanding principal balance plus
all accrued but unpaid interest shall be due and payable in full.
 
(b)            Final Payment.  Upon the Maturity Date, Borrower shall pay to
Lender all outstanding principal, interest, late charges and costs of collection
due under this Note.
 
(c)             Authorization for Direct Payments (ACH Debits). To effectuate
any payment due under this Note or under any of the other Loan Documents, the
Borrower hereby authorizes the Lender to initiate debit entries to Account
Number xxxxxxxxx at the Lender and to debit the same to such account. This
authorization to initiate debit entries shall remain in full force and effect
until the Lender has received written notification of its termination in such
time and in such manner as to afford the Lender a reasonable opportunity to act
on it. The Borrower represents that the Lender is and will be the owner of all
funds in such account. The Borrower acknowledges: (1) that such debit entries
may cause an overdraft of such account which may result in the Lender's refusal
to honor items drawn on such account until adequate deposits are made to such
account; (2) that the Lender is under no duty or obligation to initiate any
debit entry for any purpose; and (3) that if a debit is not made because the
above-referenced account does not have a sufficient available balance, or
otherwise, the payment may be late or past due.
 
3.            Prepayment.  This Note may be prepaid in whole or in part at any
time without fee, premium or penalty, unless otherwise due under any applicable
Rate Management Agreement (as defined in the Loan Agreement).  Any partial
prepayment shall be applied in accordance with paragraph 10 below and shall not
postpone the due date of any subsequent periodic installments or the Maturity
Date, or change the amount of such installments due, unless Lender shall
otherwise agree in writing.
 
4.            Late Charges. If Borrower fails to pay the installments of
interest and principal on any due date provided for herein or within ten (10)
days thereafter, then Borrower shall pay to Lender a late payment charge equal
to five percent (5%) of the amount of the unpaid installment as liquidated
compensation to Lender for the extra expense to Lender to process and administer
the late payment, Borrower agreeing, by execution hereof, that any other measure
of compensation for a late payment is speculative and impossible to compute.
This provision for late charges shall not be deemed to extend the time for
payment or be a "grace period" or "cure period" that gives Borrower a right to
cure an Event of Default. Imposition of late charges is not contingent upon the
giving of any notice or lapse of any cure period provided for in the Loan
Documents and shall not be deemed a waiver of any right or remedy of Lender,
including without limitation, acceleration of this Note.
 
5.            Maturity Date.  The then outstanding principal balance plus all
accrued but unpaid interest shall be due and payable on June 30, 2013 (the
"Maturity Date").
 
6.            Default.  A Default or an Event of Default shall be as set forth
in the Loan Agreement.
 
7.            Acceleration.  Upon the occurrence of a Default hereunder or under
the terms of any one or more of the Loan Documents, Lender may declare the then
outstanding principal and all accrued but unpaid interest immediately due and
payable and upon acceleration and thereafter this Note shall bear interest at
the Default Rate, hereinafter defined, until all indebtedness evidenced hereby
and secured by the Loan Documents has been paid in full.  Further, in the event
of such acceleration, the Loan, and all other indebtedness of Borrower to Lender
arising out of or in connection with the Loan shall become immediately due and
payable, without presentation, demand, protest or notice of any kind, all of
which are hereby waived by Borrower.  Any judgment rendered on this Note shall
bear interest at the Default Rate (as herein defined).
 
8.            Default Rate.   Default Rate shall mean and refer to a rate of
interest at the Interest Rate plus 3.0% if then permitted under applicable law.
 
9.            Application of Payments.  All sums received by Lender for
application to the Loan may be applied by Lender to late charges, expenses,
costs, interest, principal, and other amounts owing to Lender in connection with
the Loan in the order selected by Lender in its sole discretion.
 
10.        Expenses.  In the event this Note is not paid when due on any stated
or accelerated maturity date, or should it be necessary for Lender to enforce
any other of its rights under this Note, or the Loan Documents, Borrower will
pay to Lender, in addition to principal, interest and other charges due
hereunder or under the Loan Documents, all costs of collection or enforcement,
including reasonable attorneys' fees, paralegals' fees, legal assistants' fees,
costs and expenses, whether incurred with respect to collection, litigation,
bankruptcy proceedings, interpretation, dispute, negotiation, trial, appeal,
defense of actions instituted by a third party against Lender arising out of or
related to the Loan, enforcement of any judgment based on this Note, or
otherwise, whether or not a suit to collect such amounts or to enforce such
rights is brought or, if brought, is prosecuted to judgment.
 
11.        Waiver.  All persons now or at any time liable for payment of this
Note, whether directly or indirectly, hereby waive presentment, protest, notice
of protest and dishonor.  The undersigned expressly consents to any extensions
and renewals, in whole or in part, to the release of any or co-makers and any
collateral security or portions thereof, given to secure this Note, and all
delays in time of payment or other performance which Lender may grant, in its
sole discretion, at any time and from time to time without limitation, all
without any notice or further consent of Borrower, and any such grant by Lender
shall not be deemed a waiver of any subsequent delay or any of Lender's rights
hereunder or under the Loan Documents.
 
12.        Usury.  In no event shall this or any other provision herein or in
the Loan Documents, permit the collection of any interest which would be
usurious under the laws of the State of Florida.  If any such interest in excess
of the maximum rate allowable under applicable law has been collected, Borrower
agrees that the amount of interest collected above the maximum rate permitted by
applicable law, together with interest thereon at the rate required by
applicable law, shall be refunded to Borrower, and Borrower agrees to accept
such refund, or, at Borrower's option, such refund shall be applied as a
principal payment hereunder.
 
13.        Modification.  This Note may not be changed orally, but only by an
agreement in writing signed by the Lender and Borrower.
 
14.        Applicable Law.  This Note shall be governed by and construed in
accordance with the laws of the State of Florida.
 
15.        Successors and Assigns.  As used herein, the terms "Borrower" and
"Lender" shall be deemed to include their respective heirs, personal
representatives, successors and assigns.  The owner of this Note may also
disclose any such information to any regulatory body having jurisdiction over
Lender.
 
16.        Severability.  In the event any one or more of the provisions of this
Note shall for any reason be held to be invalid, illegal, or unenforceable, in
whole or in part or in any respect, or in the event that any one or more of the
provisions of this Note operates or would prospectively operate to invalidate
this Note, then and in any of those events, only such provision or provisions
shall be deemed null and void and shall not affect any other provision of this
Note.  The remaining provisions of this Note shall remain operative and in full
force and effect and shall in no way be affected, prejudiced, or disturbed
thereby.  In the event any provisions of this Note are inconsistent with the
provisions of any of the other Loan Documents, or any other agreements or
documents executed in connection with this Note, this Note shall control.
 
17.        Captions; Pronouns.  Captions are for reference only and in no way
limit the terms of this Note.  The pronouns used in this instrument shall be
construed as masculine, feminine, or neuter as the occasion may require.  Use of
the singular includes the plural, and vice versa.
 
18.        Business Day.  Any reference herein or in the Loan Documents to a day
or business day shall be deemed to refer to a banking day which shall be a day
on which Lender is open for the transaction of business, excluding any national
holidays, and any performance which would otherwise be required on a day other
than a banking day shall be timely performed in such instance, if performed on
the next succeeding banking day.  Notwithstanding such timely performance,
interest shall continue to accrue hereunder until such payment or performance
has been made.
 
19.         Information Sharing, Assignability and Confidentiality.  Borrower
agrees that the Lender may provide any information or knowledge the Lender may
have about the Borrower or about any matter relating to this Note or any of the
other Loan Documents to JPMorgan Chase & Co., or any of its subsidiaries or

purchasers of this Note or any of the other Loan Documents.  The Borrower agrees
that the Lender may at any time sell, assign or transfer one or more interests
or participations in all or any part of its rights and obligations in this Note
to one or more purchasers whether or not related to the Lender.
