position, results of operations, and cash flows from operating, investing, and
financing activities of the Company and its Subsidiaries as of the dates and for
the periods indicated, except that the unaudited consolidated interim financial
statements in the Company SEC Documents are subject to normal year-end
adjustments and were prepared in accordance with the instructions to SEC Form
10-Q and, accordingly, omit or condense certain footnotes and other information
normally included in financial statements prepared in accordance with generally
accepted accounting principles.  The consolidated financial statements
of the Company and its Subsidiaries that are included or incorporated in any
subsequent report or statement that the Company mails to its shareholders

accountants) and will fairly present the financial information that they purport
to present, except that the unaudited, consolidated interim financial statements

the books of account and financial records of the Company and the Subsidiaries

office, are accurate and complete in all material respects, and have been
maintained in accordance with good business practices, and every material
transaction affecting the Company’s or a Subsidiary’s business has been recorded
in them.

    

    (c)         Any
financial projections of the Company or any Subsidiary that have been provided
to Schaffel are reasonable, are based on reasonable assumptions and historical
results, can be supported by the Company’s or the Subsidiary’s existing customer
contracts and business arrangements, and describe in reasonable detail all
material assumptions on which they are based.

    

    (d)         Except
to the extent of the stated amount of the allowance for doubtful accounts, all
the accounts receivable and notes receivable reflected in the most recent
balance sheet included in the Company SEC Documents, and all accounts receivable
that have arisen since January 31, 2009, constitute valid and bona fide rights
to collect payments from the sale of goods and services in the ordinary course
of the business of the Company or a Subsidiary or other valid claims for which
all requisite performance has been rendered by the Company or a Subsidiary, will
be collectible by the Company or the Subsidiary in the usual and ordinary course
of business, and are not subject to any setoff, defense, or
counterclaim.  The allowance for doubtful accounts reflected on the
most recent balance sheet included in the Company SEC Documents was determined
by the Company in a manner consistent with past practices.

Balance Sheet, that have been incurred in immaterial amounts in the usual and
ordinary course of business since the Balance Sheet Date, or that do not exceed
$300,000 in the aggregate, the Company and the Subsidiaries do not have any
liabilities.  The Company has provided to Schaffel all detail and
information relating to any material liability that is accrued, reflected,
reserved, or disclosed in the Balance Sheet.  The Company is not in
violation of, or default under, any contract that could give rise to any
material liability that is not accrued, reflected, or reserved, and clearly

      exercise, purchase, exchange, or conversion price per share actually paid
      or to be paid.  If the shares of Common Stock are issued without
      consideration, the CSP will be zero.

      An
issuance of Convertible Securities that are convertible into, or exchangeable
for, shares of Common Stock without consideration will constitute for purposes
of this Section an
issuance of the maximum number of shares of Common Stock that are issuable on
the exchange or conversion of the Convertible Securities, effective as of the
date when the Convertible Securities are sold or issued.  Similarly, a
grant or issuance of Derivative Securities to purchase, subscribe for, or
otherwise acquire shares of Common Stock without consideration will constitute
for purposes of this Section an issuance of the
maximum number of shares of Common Stock issuable pursuant to the exercise of
the Derivative Securities, effective as of the date when the Derivative
Securities were granted or issued.  No further adjustment will be
required on the subsequent actual issuance of shares of Common Stock pursuant to
the exercise of the Derivative Securities or the exchange or conversion of the
Convertible Securities.

      An
amendment, extension, or modification of this Agreement or any provision of it
will be valid and effective only if it is signed by all the parties to this
Agreement.  A waiver of any provision of this Agreement will be valid
and effective only if it is evi­denced by a writing signed by or on behalf
of the party against whom the waiver is sought to be enforced.  At any
time on or before the Closing Date, and regardless of whether this Agreement has
been approved by any third party or by the members, managers, partners,
trustees, shareholders, or board of directors of a party to this Agreement, the
parties to this Agreement may in writing: (a) extend the time for performance of
any of the obligations or other actions of the other parties; (b) waive any
inaccuracies of the representations or warranties of the other parties contained
in this Agreement; (c) waive compliance with any of the covenants of the other
parties contained in this Agreement; (d) waive performance of any of the
obligations of the other parties created under this Agreement; or (e) waive any
of the conditions precedent to its own obligations under this
Agreement.  No delay or course of dealing by a party to this Agreement
in exercising a power, right, or remedy under this Agreement will oper­ate
as a waiver of any power, right, or remedy of that party, except to the extent
expressly manifested in a writing signed by or on behalf of that
party.  In addition, the written waiver by a party of a power, right,
or remedy under any provision of this Agreement will not constitute a waiver of
any succeeding exer­cise of the power, right, or remedy or a waiver of the
provision itself.

    AEROSONIC CORPORATION (the
“Company”),
a Delaware corporation, OP
TECHNOLOGIES, INC., an Oregon corporation, and AVIONICS SPECIALTIES, INC., a
Virginia corporation, (individually, a “Borrower”
and, collectively, “Borrowers”),
for value received, jointly and severally promise to pay without setoff,
defense, or counterclaim to the order of MARTIN L. SCHAFFEL (the “Lender”),
at maturity, the principal amount of Five Hundred Thousand Dollars (US
$500,000), and to pay on a monthly basis interest on the unpaid principal amount
from the date of this 14% Subordinated Note (this “Note”) at
the rate, on the date, and subject to the conditions and limitations specified
in this Note.

              Note.

            

    

    

    This Note
is limited to an aggregate principal amount of $500,000 shall be available to
the Borrowers on the Effective Date (the “Note”)
and issued pursuant to the Loan Agreement dated May 14, 2009, by and between the
Company and the Lender (as amended from time to time, the “Loan
Agreement”).  The terms and conditions of the Loan Agreement
are incorporated by reference into this Note.

              Defined
      Terms.

            

    

    

    “Maturity
Date” means the earlier of:  (i) April 10, 2010, or (ii) the
maturity of the Existing Loans.  

    

    All
capitalized and uncapitalized terms that are defined in Section 1.1 of the Loan
Agreement and used in this Note have the meanings attributed to those terms in
the Loan Agreement, and those definitions are incorporated by reference into
this Note.

              Interest.

            

    

    

    Interest shall accrue monthly on the
unpaid principal amount of this Note from the date of this Note until the April
10, 2010 (the “Maturity
Date”) at an annual rate of 14% and shall be payable commencing on June
1, 2009 and continuing on the same calendar day of each consecutive month until
the Maturity Date when one final payment of the entire balance of principal,
interest, fees (including Event of Default Fee, if applicable), premiums,
charges, costs and expenses then outstanding on this Note shall be due and
payable in full.  Interest is payable on demand on any payment of
principal or interest under this Note that is not paid when due, for the period
commencing on the day following the day when Interest was last timely paid in
accordance with the terms of this Section 3 and continuing until paid, at an
annual rate equal to 16%.  Borrowers and the Lender intend to comply
strictly with applicable law regulating the maximum allowable rate or amount of
interest that the Lender may charge and collect on this
Note.  Accordingly, and notwithstanding anything in this Note to the
contrary, the maximum, aggregate amount of interest and other charges
constituting interest under applicable law that are payable, chargeable, or
receivable under this Note shall not exceed the maximum amount of interest now
allowed by applicable law or any greater amount of interest allowed because of a
future amendment to existing law.  Borrowers are not liable for any
interest in excess of this maximum amount, and any excess interest charged or
collected by the Lender will constitute an inadvertent mistake and, if charged
but not paid, will be cancelled automatically, or, if paid, will be either
refunded to Borrowers or credited against the outstanding principal balance of
the Note, at the election of the Lender.

    If the
Note is not paid in full when due, whether at stated maturity or upon
acceleration of the Maturity Date pursuant to a Default, the Borrowers jointly
and severally shall pay to the Lender a fee of $25,000 (the “Event of Default
Fee”) on the date when the Note became due and payable (whether at stated
maturity or upon acceleration of the maturity date pursuant to a
Default).  In addition, upon a Default, the Company will immediately
register the Advance Shares issued to Redmond in connection with the Note and
the Warrant Shares issued upon exercise of the Warrants in accordance with the
provisions set forth in the Loan Agreement and the Warrant, as
applicable.

              Payment
      of Note.

            

    

    

    Borrowers
may prepay the Note in full at any time or in part from time to time without
penalty, premium, or advance notice to the Lender.  Borrowers shall
provide the Lender with prior written notice of any prepayment, whether in full
or in part.  Upon full payment of this Note (including all costs,
principal, and accrued interest), the Lender shall surrender it to the Company
for cancellation.

              Place

    Borrowers shall pay all principal and
interest under this Note, and if applicable, the Event of Default Fee, by wire
transfer to an account designated by the Lender.  If any payment date
under this Note occurs on a day that is a Saturday, Sunday, or bank holiday in
Tampa, Florida, that payment date will be extended automatically to the next
succeeding day that is not a Business Day.  Borrowers shall pay all
principal and interest due under this Note, and if applicable, the Event of
Default Fee, without any presentation of this Note.  Any partial
prepayment of this Note before the Maturity Date will be applied first to
accrued interest, and then to principal.  Any payment or prepayment of
this Note in full will be applied first to the then accrued interest, and then
to principal.

              Subordination.

            

    

    

    By
accepting this Note, the Lender agrees that the Loan is subordinated and subject
to the right of prior payment in full of all the Existing
Loans.  Borrowers shall not make any payment on account of the Loan,
or apply any of their respective assets or property to retire or purchase any of
the Loan, if, at the time of payment or application, a default or event of
default exists and is continuing in the payment of any principal or interest
then due and payable under the terms of the Existing Loans.  Nothing
in this Note prevents the Lender from exercising all remedies otherwise
permitted by law, this Note, or the other Financing Documents upon the
occurrence of a “Default,” subject to the provisions of the Financing Documents
and any rights of the holder of Existing Loans under the foregoing subordination
provisions to receive cash, property, or securities otherwise payable and
distributable to the Lender on account of this Note.

              Events
      of Default.

            

    

    

    The
occurrence of one or more of the following events will constitute a “Default”
under this Note:

    

    (a)         the
failure of Borrowers to pay within ten (10) days following its due date, any
payment described herein, whether of principal, interest or
otherwise;

    

    (b)         any
default or event of default under the Existing Loan Documents;

    

    (c)         any
default, or event of default under any of the Financing Documents;

    

    (d)         any
default, or event of default under any loan to an Other Lender; or

    

    (e)         a
borrowing by one or more of the Borrowers for the purpose of repaying any amount
payable under the Existing Loan Documents, unless the borrowing is on more
favorable terms to the Borrowers.

    

    If a
“Default”
occurs, the entire unpaid principal amount of this Note, together will all
amounts owing under this Note, including interest, will become immediately due
and payable without further demand or notice by the Lender, and the Lender may
proceed to protect its rights in the manner provided by applicable law and the
Financing Documents.  As set forth in Section 3, if a Default occurs,
interest is payable on demand on any payment of principal or interest under this
Note that is not paid when due, for the period commencing on the day following
the day when Interest was last timely paid and continuing until paid, at an
annual rate equal to 16%.  If this Note is not paid in full whenever
it becomes due and payable, Borrowers agree to pay all costs and expenses of
collection, including reasonable attorneys’ fees.  Notwithstanding any
of the foregoing, at any time during the term of the Loan the Existing Lender
waives (or is deemed to have waived through extension, forbearance or otherwise)
any Default under any of the Existing Loans, such waiver shall constitute a
waiver of such Default under the Loan.

    Each
Borrower and every other person liable at any time for payment of this Note
waives presentment, protest, notice of protest, and notice of
dishonor.  A waiver, discharge, extension, amendment, termination, or
modification of this Note will be valid and effective only if it is evidenced by
a writing signed by or on behalf of the party against whom the waiver is sought
to be enforced.  No delay or course of dealing by the Lender in
exercising any power, right, or remedy under this Note will operate as a waiver
of any power, right, or remedy of the Lender, except to the extent expressly
manifested in a writing signed by or on behalf of the Lender.  In
addition, the written waiver by the Lender of a power, right, or remedy under
any provision of this Note will not constitute a waiver of any other succeeding
exercise of the power, right, or remedy or a waiver of the provision
itself.  A written waiver or consent by the Lender is binding on every
subsequent holder of this Note.

    

    Each
Borrower consents to all extensions and renewals of this Note (as a whole or in
part) and all delays and indulgences in time of payment or other performance
under this Note that the Lender grants at any time and from time to time,
without limitation and without notice to or further consent of any
Borrower.

the application of that provision to a person or circumstance to which it is
valid and enforceable.
