Mr. Edward L. Stern
President & CEO
Kreisler Manufacturing Corporation
5960 Central Avenue, Suite H
St Petersburg, FL 33707

Dear Mr. Stem:

     The purpose of this letter ("Financial Advisory Engagement Letter") is to
set forth the terms of the engagement by Kreisler Manufacturing Corporation (the
"Company") of Oasis Ventures, LLC (the "Adviser") to render financial advisory
and investment banking services to the Company in connection with any possible
Transaction (as defined herein). The Company and the Adviser may hereinafter
also be referred to together as the "Parties" and separately as the "Party". The
Adviser agrees to use reasonable good efforts in rendering these services.

     Mr. Robert S. Krupp shall perform most of the services on behalf of the
Adviser and it is anticipated that the services will be supplied primarily at
the offices of the Adviser, secondarily at the Company's offices, and at any
other locations reasonably required by the Company and reasonably acceptable to
the Adviser. The Adviser makes no representations nor warranties as to the
results of its rendering of financial advisory services.

CONFIDENTIALITY
---------------

     The Adviser agrees to keep confidential all non-public information that it
receives concerning the Company and any transaction and to disclose that
information only with the consent of the Company, except as it is legally
required or obliged to do so under applicable law.

TERM
----

     The term of this engagement (the "Term") shall be from the date hereof (the
"Commencement Date") to either: i) fifteen (15) business days following the date
of the Closing of any Transaction, ii) one year from the date hereof, or iii)
thirty (30) days following the written notification by one Party to the other
Party of the early termination of the Agreement, whichever occurs first.
<PAGE>

CURRENT SITUATION
-----------------

     The Company may require the financial advisory and investment banking
services of the Adviser to assist it in directing the possible sale and related
activities of the Company.

APPROACH
--------

     In general, the engagement shall be divided into four phases. Phase I
entails generating a valuation estimate based upon Company's forecasts. Phase II
involves revising and updating of an information memorandum for use in any
selling process. Phase III encompasses the selling process and the negotiation
of a letter of intent. Phase IV is the negotiation of definitive documents,
related activities and the Closing. Due diligence is usually performed during
Phases III and IV. The four phases are estimated to take three to five months to
complete. The actual elapsed time may be more or less depending on various
factors, including but not limited to: i) the Company's financial performance,
ii) the number of potential buyers, iii) the quality and timeliness of the
Company's input and iv) the condition of the markets. The Adviser will provide
guidance and oversight during all of the phases of the engagement; and personnel
of the Adviser will assist in finalizing the forecast provided by the Company in
Phase I. The Company will have significant responsibility for work product in
Phases I and II and the due diligence process. The Adviser, along with Company's
legal counsel, will have primary responsibility for Phases III and IV.

FEES AND EXPENSES
-----------------

     For providing the services hereunder, the Company agrees to pay the Adviser
a non-refundable retainer fee of $65,000, payable upon signing of this
Agreement; payment of the retainer fee will be credited against any Performance
Fee payable hereunder.

     In the event any Transaction is completed, whether or not the Adviser is
responsible for introducing the buyer to the Company, within twenty-four (24)
months of the Commencement Date, the Company shall immediately prior to the
closing of the Transaction (the "Closing") pay by wire transfer to the Adviser a
success fee (the "Performance Fee"). The Performance Fee shall be an amount
equal to 3% (three percent) of the Purchase Consideration (defined below). For
purposes of calculating the Performance Fee, "Purchase Consideration" shall
include the cash and debt portions of the purchase price, the fair market value
(determined in accordance with Schedule I hereto) of stock, notes or other
securities received by the Company or its shareholders, Company debt assumed or
accepted by the purchaser, earn-out payments paid, assets or cash distributed to
shareholder(s) of the Company prior to or after the Closing, and any other value
received by the shareholder(s) for their Company shares; but shall be before any
deductions for any Transaction expenses. Any portion of the Performance Fee
relating to any earn-out payments shall be immediately due and payable when the
value, if any, of any earn-out is received by the stockholders or the Company.

     For purposes of this Agreement, a "Transaction" would include the sale of a
controlling interest in the Company by way of merger, sale of assets, or sale of
stock, including without limitation a management or other leveraged buyout.
<PAGE>

     Whether or not a Transaction is completed, the Adviser shall also invoice
the Company at the end of each calendar month and the Company shall pay within
fifteen (15) days after the receipt of the Adviser's invoice, for all reasonable
out-of-pocket business expenses incurred during the Term, including but not
limited to, travel expenses (the equivalent of up to the cost of Y class airfare
plus reasonable upgrades, travel to/from the airport, lodging, meals, laundry,
etc.), pre-approved business entertainment, supplies, telephone, fax, postage,
overnight delivery and outside research services. The Adviser shall provide
adequate detail of such expenses and receipts as required by the Company in
order to make the expenses fully tax deductible to the Adviser. The Company
shall pay or reimburse the Adviser for any state sales/service tax, if
applicable.

EARLY TERMINATION
-----------------

     Either Party may terminate this Agreement by thirty (30) days notice to the
other Party. The Company may direct the Adviser to provide no services during
the thirty (30) days following such notification. The Company shall be obligated
to pay the Adviser promptly for all services (including travel time) performed
by the Adviser prior to such notification and for travel time to return to San
Francisco, California if after such notification. The Company shall reimburse
the Adviser for reasonable out-of-pocket expenses (including state sales/service
tax, if any) incurred by the Adviser or for which the Adviser became obligated
prior to the early termination date. Early termination by the Company of the
Agreement shall not relieve the Company of its obligation to pay the Adviser any
Performance Fee, which would otherwise be due and payable.

FLIGHT TO INDEMNIFICATION
-------------------------

     The Company hereby agrees to indemnify, defend and hold harmless the
Adviser and its shareholders, directors, agents, employees, independent
contractors, successors and assigns (the "Indemnified Parties") against and from
any and all claims, demands, liabilities, losses, damages, costs or expenses
(including reasonable attorney's fees and reasonable fees for the Adviser's
time, if required) arising out of or in any way connected with any acts or
omissions in connection with this engagement of the Adviser by the Company,
regardless or whether or not any such claims, demands, liabilities, losses,
damages, costs or expenses were caused in whole or in part by any Indemnified
Parties. The right to indemnification as set out in the preceding sentence shall
not extend to any claims, demands, liabilities, losses, damages, costs or
expenses arising out of the gross negligence, bad faith or wilful misconduct of
any Indemnified Parties. The right to indemnification provided herein shall
remain operational and in full force and effect regardless of any termination or
the completion or expiration of the Agreement or the Adviser's engagement by the
Company.
