                            VOTE THE GREEN PROXY CARD


The Wynnefield  Group is a long-time  investor and owner of a 29.7 percent stake
in First Aviation  Services Inc. (FAvS). As a significant  minority  shareholder
whose  interests  are  aligned  with  those  of  other  minority   shareholders,
Wynnefield is soliciting  proxies in OPPOSITION TO  MANAGEMENT'S  DIRECTOR SLATE
AND IN ORDER TO IMPLEMENT CUMULATIVE VOTING.


We have been dismayed at FAvS'  performance,  performance that has resulted in a
stock price BELOW BOOK VALUE FOR MORE THAN THREE YEARS AND NEAR NET/NET  WORKING
CAPITAL  (LIQUIDATION  VALUE) PER SHARE RECENTLY.  THIS PRICE INDICATES THAT THE
MARKET ASSIGNS ONLY NOMINAL VALUE TO FAVS' BUSINESS.  On several  occasions,  we
have  urged  that   management  take  steps  to  benefit  the  company  and  ALL
shareholders  by  developing  and  executing  a  successful   business  plan  or
undertaking a value-releasing  transaction.  After being repeatedly rebuffed, we
now have no other choice but to engage in a proxy contest.


FAVS BLAMES  INDUSTRY  CONDITIONS FOR ITS LACK OF  PERFORMANCE.  However,  FAvS'
primary  competitor AVIALL (AVL) HAS EVOLVED ITS BUSINESS PLAN and continues its
strong recovery since 2001.

FAVS' CEO AND CHAIRMAN  (THROUGH THEIR INVESTMENT FIRM, FIRST EQUITY GROUP INC.)
OWN 51% OF FAVS STOCK and  therefore  have COMPLETE  VOTING  CONTROL IN DIRECTOR
ELECTIONS.  We believe THE VOICE OF MINORITY  SHAREHOLDERS  HAS BEEN  IGNORED BY
FAVS MANAGEMENT FOR TOO LONG. FAvS management  benefits from salaries,  bonuses,
and payments to First Equity.


We seek to give ALL minority shareholders a voice at FAvS by electing a minority
shareholder  to ONE of the  five  board  seats  and  through  implementation  of
cumulative voting. NELSON OBUS WILL BRING TO THE BOARD NEEDED FRESH THINKING and
a voice for ALL minority  shareholders.  CUMULATIVE VOTING WILL MAKE IT POSSIBLE
FOR MINORITY SHAREHOLDERS TO ELECT ONE DIRECTOR OF THEIR CHOICE.


With management  controlling 51% of FAvS stock, minority shareholders cannot win
this proxy contest without management support. It is therefore important that as
many shareholders as possible send a message to the board by voting "FOR" Nelson
Obus and "FOR" cumulative  voting.  WE HOPE THAT THE BOARD WILL HEAR THE MESSAGE
AND ADOPT MEASURES TO GIVE MINORITY SHAREHOLDERS A SINGLE SEAT ON THE BOARD.


We urge you to return our GREEN proxy card or  download  our proxy card by [link

holds your shares, instruct them to vote your shares "FOR" Nelson Obus and "FOR"
cumulative voting.
