Mr. Harold K. Fletcher
Tel-Instrument Electronics Corp.
728 Garden Street
Carlstadt, NJ 07072

Dear Hal:

      We want to confirm the terms and provisions pursuant to which Semaphore
Capital Advisors, LLP ("Semaphore") will act as investment banker for Tel
Instrument Electronics Corp. (the "Company"). This agreement supercedes all
prior written and oral agreements between us (and with our predecessor in
interest), which prior agreements are hereby declared null and void.

Section I: Services to be Rendered

      A)    Our services as investment banker will include (but not be limited
            to) the following, as requested by the Company:

            (i) Consulting with the Company and assisting in the development of
a long-term strategic plan for realizing the value of the Company's assets,
initiating discussions and negotiations with investor candidates, including
strategic investor candidates (defined as corporations or other business
entities in similar or related businesses or industries, hereinafter referred to
as "Strategic Investors") and merger or acquisition candidates ("Merger
Candidates"), as well as potential financial investment candidates (Strategic
Investors, Merger Candidates and financial investment candidates are called
herein collectively "Candidates"), and for achieving other agreed upon financial
objectives;

            (ii) Advising the Company with respect to possible merger
opportunities or acquisition candidates, including financial analysis, the
receptivity of the financial markets and the effects on the Company of pursuing
various opportunities;

            (iii) Attempting to arrange a sale of existing shares of the
Company's stock held by certain shareholders to be identified by the Company, if
requested by the Company, as part of an investment or separately, in one or more
series of block sales or Transactions at market price or at another price that
may be negotiated between the shareholders and one or more buyers introduced by
us;


            (iv) Assisting the Company in raising capital by (a) arranging a
private placement of the Company's securities in the amount and on the terms
agreed in writing and/or (b) advising on and assisting in obtaining an
underwriter for a public offering of the Company's securities in such amount and
on such terms as are agreed in writing;

            (v) Providing any other investment banking, financial, advisory or
management-consulting services as may be agreed in writing between us and the
Company, including (but not limited to) reviewing other business opportunities,
rendering an opinion as to the potential impact of such business opportunities
on the Company's valuation and assisting management in identifying candidates
for the Board of Directors if requested by the Company.

      B) Information Memorandum. We will assist in the preparation of a private
placement, executive summary, investment or information memorandum ("Information
Memorandum"), which Information Memorandum may be in one or more formats and
will include an executive summary and a business plan with detailed historical
and projected financial statements which will describe the Company, its current
and proposed future businesses, the Company's management and the investment
opportunity. The Information Memorandum will also incorporate any other relevant
information that may be customary and necessary or may be deemed by you and us
to be desirable. The Company confirms that, in assisting in the preparation of
the Information Memorandum, we will be relying upon information, both written
and oral, and documents and data furnished by the Company to us or which have
been approved by the Company, as well as information from generally recognized
public sources (the "Information").

      C) Information and Documents. The Company will furnish to us such
information, documents and other materials, respond to requests for information
and take such other action as (i) shall be reasonably requested by us so as to
permit and facilitate the carrying out of our activities under this Agreement
and (ii) shall be reasonably requested by any Candidates (if approved by the
Company) in connection with their analysis or due diligence review of a
Transaction. (A "Transaction" is defined herein as any investment, corporate
acquisition, merger, business combination or other corporate event described in
Section I, A, (I) - (IV).) If any event shall occur or condition develop as a
result of which it is necessary or advisable, in our opinion, to amend or
supplement any such previously furnished documents or materials in order that
they will not contain an untrue statement of a material fact or omit any
material fact necessary to make the statements made therein not misleading, then
the Company shall prepare or cause to be prepared such updated, additional or
supplemental documentation, which shall be acceptable to us for delivery to
Candidates for the purpose of correcting such statement or omission. In the
event that the Company determines that no such amendment or supplement is
required, we may terminate the Agreement. The Company may unilaterally decide to
amend, update, revise or add supplemental data to the Information at any time it
chooses and we may distribute such updated information and documents to the
Candidates. We agree that we will only distribute information or documents
pursuant to this Agreement, which we in good faith believe to be in compliance
with Federal and state securities and other laws.


                                       2


      We will not provide an Information Memorandum or other confidential
information about the Company to any Candidate that is in a business similar to
or competing with the Company unless such Candidate executes a confidentiality
or non-disclosure agreement acceptable to the Company. We will use our best
effort to obtain an executed non-disclosure agreement before providing an
Information Memorandum or other confidential information to any other Candidate,
not in a similar or competing business. In any event, we will not provide an
Information Memorandum or Confidential Information to any Candidate unless first
approved by the Company.

      The Company shall be under no obligation to negotiate with any Candidate
and the Company has the sole discretion whether or not to enter into a
definitive agreement for a Transaction with a Candidate.

Section II: Fees, Expenses and Term

      A) Term. We will be the exclusive investment bankers to the Company
commencing on the date of execution of this Agreement by both parties, provided
however, that either party may withdraw from this Agreement at any time upon
thirty days written notice to the other party given in accordance with Section
IV, F, hereof.

      B) Post Termination. Within three business days after the effective date
of any termination by the Company (the "Termination Date"), we will deliver to
the Company a list of all Candidates (the "Covered Parties") with which we can
confirm that (a) the Company, at our instigation or by our introduction, has had
discussions or one or more meetings concerning a Transaction or has specifically
requested Semaphore to have such a discussion during the term of this Agreement
and prior to receipt of the notice of termination or (b) such Covered Parties
have, prior to such notice of termination, expressed an interest in considering
or pursuing a Transaction by requesting a copy of the Information Memorandum
after qualifying discussions with us and have received such Information
Memorandum. Covered Parties shall not include Candidates contacted by us that
have indicated they are not interested in the Company either during a
preliminary qualifying conversation or after reading an executive summary or
other preliminary business description.

      If the Company completes a Transaction with a Covered Party, within
eighteen months of the termination of this Agreement, Semaphore shall be
entitled to the fees set forth under subsections C, (iii) and (iv) or subsection
(D) under this Section II.

      On and after the Termination Date, we shall also, upon request, either
destroy or return to the Company any and all Information, Information Memoranda,
documents and confidential information of the Company (including extracts
thereof), which are in our possession or control; except that we may keep copies
of documents if required by NASD or SEC rules. The provisions concerning
confidentiality, indemnification, compensation and the Company's obligation to
pay fees and reimburse expenses contained herein, and ours and the Company's
obligations contained in the Indemnification provisions, will survive any such
termination, except to the extent expressly stated otherwise herein. We agree
not to use any confidential


                                       3


information about the Company provided to us by the Company for any purpose
other than in connection with our services hereunder or as directed by the
Company.

      C) Compensation. The Company agrees to pay us the following compensation
for our services hereunder (provided that no such fee shall apply to any
Transaction with a current officer, director, shareholder or employee of the
Company, or any family member or affiliate of any such person, all contrary
provisions notwithstanding):

            (i) A non-refundable retainer in the amount of $30,000.00, payable
in three installments, the initial $10,000.00 of which shall be paid upon
signing this agreement and the remaining two installments of $10,000.00 each
shall be paid in thirty-calendar-day increments beginning thirty days after the
initial payment and the third shall be paid sixty calendar days after the
initial payment. The retainer is intended to compensate us for investment
banking services, particularly as described in subparagraphs (i), and (ii) in
Section I. The Company considers time of the essence in connection with these
services and if, in the Company's reasonable judgment, we have not provided the
services contemplated hereunder in a diligent manner, the Company may exercise
its termination rights any time after sixty days from the date thereof, and
after such termination, no further amounts specified in this subparagraph (i)
shall be due and payable. In the event that we exercise our termination rights,
no further amounts under this subparagraph (i) shall become due and payable.

            (ii) Monthly Payments. Commencing on the 90th day after execution
hereof, the Company will pay Semaphore $5,000 per month, in advance, for the
investment banking services set forth in this Agreement, for as many months as
both the Company and Semaphore agree. In the event that either party wishes to
terminate the arrangement set forth in this Paragraph C (ii), such Party shall
give the other Party 15 days written notice thereof in accordance with Section
IV, F.

            (iii) Success Fee. A Success Fee which shall be a percentage
(defined below) of the Aggregate Consideration (except as further defined below)
received by the Company from a Transaction closed with a Candidate (or upon
closing a Transaction with a Covered Party, as defined in Section II, B, within
twelve months after the Termination Date), which Success Fee will be paid when
the Company receives the proceeds from the Transaction. The Success Fee is
calculated as a percentage of the proceeds from the Aggregate Consideration
(except as further defined in subsection E below) of any Transaction (or, in the
event of a second transaction on an accumulated basis) according to the
following formula:

                  8% on the first $5 million of transaction;
                  5% on the next $2.5 million;
                  2% on the next $2.5 million;
                  1% on the excess over $10 million.

      The $30,000 of monthly payments made under paragraph C (i) above shall be
credited against the Success Fee payable under this subparagraph (iii) but shall
not affect the warrants issuable under subparagraph (iv) below.


                                       4


In no event will the Success Fee payable be less than $100,000.

            The Success Fee payable to Semaphore for raising capital for the
Company, in lieu of the above percentages, shall be 3% of the amount of
mezzanine capital, 1% of bank debt and the percentages set forth above, for
raising equity.

            (iv) Warrants. In addition to the Success Fee set forth above, the
Company will issue to Semaphore, 5 year warrants to purchase shares of common
stock of the Company.

            The warrants shall contain usual and customary exercise rights,
terms and conditions (to be covered in a separate warrant agreement) and shall
be exercisable (a) for that number of shares of common stock that shall be equal
to 12.5% of the dollar amount of the Success Fee except that warrants issuable
in connection with raising mezzanine financing shall be exercisable for Shares
equal to 5% of the dollars so raised, and there shall be no warrants issuable in
connection with raising bank debt; and (b) at a price per share equal to the
value per share used in the Transaction, or if none, or if the Transaction
effects a change of control, then at the closing price on the American Stock
Exchange on the 20th business day prior to public disclosure of the letter of
intent or the Transaction, whichever is sooner.

            For example, Semaphore's compensation based on a $5 million
transaction shall be equal to success fee of $400,000 (8% x $5MM) less a $30,000
credit for the retainer paid and 5 year warrants to purchase 50,000 shares of
common stock (12.5% of the dollar amount of the Success Fee) at an exercise
price per share equal to the value of the shares in the Transaction, or if none,
or if the Transaction effects a change of control then at the Closing price on
the Amex, 20 business days before public disclosure of the letter or intent or
Transaction, whichever is sooner.

            (v) The Company will also reimburse Semaphore for all documented,
reasonable, out-of-pocket expenses incurred directly in connection with the
completion of the first Transaction, in an amount not to exceed $10,000.

            (vi) Reset Provisions. In the event of a transaction in excess of
$20 million in Aggregate Consideration, or in the event of a full auction sale
of the Company, the Compensation payable to Semaphore shall be (a) a Cash
Success Fee equal to 2% of the aggregate consideration of such Transaction,
except that in the case of a full auction sale of the Company, the Cash Success
Fee shall not be less than $600,000 and (b) warrants, calculated pursuant to the
same formula used in subparagraph IV above.

            Other transactions, if any, and the formula used in subparagraphs
(ii) and (iv) of this Subsection C, shall not be otherwise taken into account in
calculating the Reset Provision.

      (D) Subsequent Transactions. If a Transaction is consummated with a
Candidate, then at any time thereafter prior to the anniversary of the date of
termination of this Agreement, if the Company closes any additional Transaction
or business combination with such Candidate, we will be entitled to receive a
fee in cash payable upon the receipt of the proceeds from any


                                       5


such Transaction or business combination, based on the Aggregate Consideration
of the Transaction or business combination using the following formula:

            i.    Two and one-half percent (2.5%) of the first five million
                  dollars of Aggregate Consideration or part thereof, plus

            ii.   One percent (1%) of any remaining Aggregate Consideration.

      (E) Aggregate Consideration. For purposes of this Agreement, "Aggregate
Consideration" shall mean the total value of all cash, securities, other
property and any other consideration, including, without limitation (as, if and
when received), any contingent, earned or other assets or consideration, aid or
payable, directly or indirectly, in connection with the Transaction, net of any
indebtedness owed upon the same, it being the intention of this provision that
the Aggregate Consideration shall mean the net equity value of any cash,
tangible assets or measurable intangible assets acquired by, invested in, loaned
to or transferred to the Company. The fair market value of any securities
(whether debt or equity) or other similar property shall be determined by the
closing or last sale prices of these securities (in the principal market on
which the are traded) on the date of the consummation of the Transaction or the
valuation of other assets placed upon them by the parties to the Transaction. If
any non-cash consideration is a class of newly-issued, publicly-traded
securities, then the fair market value thereof shall be the average of the
closing prices for the twenty trading days subsequent to the fifth trading day
after the consummation of the Transaction. If no public market exists for any
securities issued in the Transaction or a class of securities is not intended to
be publicly traded or convertible into publicly-traded securities, then the fair
market value thereof shall be determined by the valuation placed upon these
securities by the parties to the Transaction.

      In the event that the Company completes more than one Transaction during
the term hereof, the Aggregate Consideration of all Transactions shall be
combined for the purposes of applying the Success Fee schedule.

      (F) Notwithstanding any other provision herein, particularly including the
exclusivity provisions, the parties agree that:

            (i) The current agreement among the Company, Semaphore and
Investment Partners Group, shall continue according to its terms and the Company
may extend such agreement on the same terms; and

            (ii) The Company may raise mezzanine and bank debt on its own,
without using Semaphore for this purpose, and no fee will accrue to Semaphore in
respect of any such mezzanine or bank debt raised by the Company; and

            (iii) Directors, officers or shareholders may bring potential
merger, acquisition or other business combination candidates to the attention of
the Board and the Board may, if it chooses, pay such directors, officers or
shareholders a finders fee.


                                       6


      It is the intent of this agreement that the Company will compensate
Semaphore only for investment banking services outlined in Section 1, which are
requested by the Company and provided by Semaphore.

Section III: Indemnification

      In consideration of our services on behalf of the Company in connection
with any offering of securities, the Company agrees to indemnify and hold us
harmless and each of our affiliates, stockholders, directors, officers,
employees, agents and controlling persons (within the meaning of ss.15 of the
Securities Act of 1933) to the extent and as provided for in the indemnification

Section IV: Other

      A) Exclusivity. During the period that we are engaged by the Company, the

of all parties with whom the Company, its directors, officers and/or its
controlling shareholders have conducted any discussions, received inquiries from
or had any other related contacts within three months prior to the date hereof,
concerning any potential investment in the Company or in any related Transaction
with the Company and shall promptly inform us of the identity of any third party
that subsequently makes any such inquiry and whose interest in a possible
investment in the Company or in any other form of Transaction subsequently
becomes known to the Company during the term of this Agreement.

      B) Confidentiality. Each party to this Agreement agrees to keep in strict
confidence the proprietary and non-public information of the other party during
the term of this Agreement and thereafter, provided, however, that the foregoing
shall not prohibit disclosures (i) permitted by the parties in performing its
obligations hereunder; (ii) required by law or legal process (provided notice is
given prior to such disclosure); or (iii) of matters which become public other

      C) No Brokers. The Company represents that, to the best of its knowledge,
there are no brokers, representatives or other persons that have an interest in

      D) Applicable Law. This Agreement shall be constructed and enforced in

any dispute thereunder. Service of process hereunder may be effected any where
by such court's procedures or pursuant to the notice provisions set forth in
