Dear Stockholder:

     We invite you to attend the 1998 Annual Meeting of Stockholders (the
"Meeting") of Aviation Sales Company ("AVS") to be held at      a.m. on
  , 1998, at                  . The purposes of the Meeting are (i) to consider
and vote upon a transaction whereby AVS will issue 2,844,079 shares of AVS
common stock, $0.001 per share par value ("AVS Common Stock"), subject to
adjustment, in exchange for all of the outstanding common stock of Whitehall
Corporation, a Delaware corporation ("Whitehall") and will issue up to 257,150
shares of AVS Common Stock upon exercise of outstanding options to purchase
Whitehall common stock pursuant to an Agreement and Plan of Merger ("Merger
Agreement"), dated as of March 26, 1998, by and among AVS, WHC Acquisition
Corp., a Delaware corporation and a wholly-owned subsidiary of AVS (the "Sub")
and Whitehall (the "Merger Proposal"); (ii) to elect two persons to AVS's Board
of Directors to serve until the 2001 Annual Meeting of the Stockholders or
until election and qualification of their respective successors; (iii) to
ratify the selection of AVS's independent auditors for the 1998 fiscal year;
and (iv) to transact such other business as may properly come before the
Meeting.

     The Merger Agreement provides for the conversion and exchange of each
outstanding share of common stock of Whitehall (the "Whitehall Common Stock")
into the right to receive .5143 shares of AVS Common Stock. The accompanying
proxy statement contains detailed information concerning the other terms of the
Merger Proposal and certain additional information. Please give all of this
information your careful attention. A copy of the Merger Agreement is included
as Annex A to the accompanying proxy statement and should be read in its
entirety.

     Your Board of Directors (the "AVS Board") has carefully reviewed and
considered the terms and conditions of the Merger Agreement. In connection with
this review and consideration, the AVS Board retained SBC Warburg Dillon Read
("SBCWDR") which has rendered an opinion (the "SBCWDR Opinion") to the effect
that the proposed exchange ratio of .5143 shares of AVS Common Stock for each
share of Whitehall Common Stock is fair from a financial point of view to the
holders of AVS Common Stock. A copy of the SBCWDR Opinion, which sets forth the
matters considered and the scope of review underwritten in connection
therewith, is included as Annex B to the accompanying proxy statement.

     Whether or not you plan to attend the Meeting, please complete, sign and
date the enclosed proxy card and return it in the enclosed postage-paid
envelope, as soon as possible. If you attend the Meeting, you may vote in
person if you wish, even though you have previously returned your proxy card.

     The accompanying proxy statement provides a detailed description of the
Merger Proposal and the business of AVS and Whitehall, as well as risks
associated with the Merger Proposal, which are set forth in the section
entitled "Risk Factors." Please give all of this information your careful
attention.


                              Very truly yours,

shares of AVS Common Stock upon exercise of outstanding options to purchase
Whitehall Common Stock pursuant to an Agreement and Plan of Merger ("Merger
Agreement") dated as of March 26, 1998, by and among AVS, WHC Acquisition
Corp., a Delaware corporation and a wholly-owned subsidiary of AVS (the "Sub")

     The cost of the AVS Board's proxy solicitation will be borne by the AVS.
The directors, officers and principal stockholders of AVS who collectively own
of record       (or     %) of AVS Common Stock outstanding as of the record
date of         , 1998, have indicated their intention to vote in favor of the
Merger Proposal, the election of the two nominees as directors of AVS and the

solicitation by mail, directors, officers and employees of the AVS may solicit
proxies personally and by telephone and telegraph, all without extra
compensation.
     At the close of business on         , 1998 (the "Record Date"), AVS had
outstanding       shares of AVS Common Stock. Each share of AVS Common Stock
entitles the holder thereof on the Record Date to one vote on each matter
submitted to a vote of stockholders at the Meeting. Only stockholders of record
at the close of business on the Record Date are entitled to notice of and to
vote at the Meeting. In the event that there are not sufficient votes for
approval of any of the matters to be voted upon at the Meeting, the Meeting may
be adjourned in order to permit further solicitation of proxies. The quorum
necessary to conduct business at the Meeting consists of a majority of the
outstanding shares of AVS Common Stock.
     Shares represented by proxies which are marked "abstain" or which are
marked to deny discretionary authority will only be counted for determining the
presence of a quorum. Votes withheld in connection with the election of one or
more of the nominees for director will not be counted as votes cast for such
individuals. In addition, where brokers are prohibited from exercising
discretionary authority for beneficial owners who have not provided voting
instructions (commonly referred to as "broker non-votes"), those shares will
not be included in the vote totals.
     A list of stockholders entitled to vote at the Meeting will be available
at AVS's principal executive office located at 6905 N.W. 25th Street, Miami,
Florida 33122 for a period of ten (10) days prior to the Meeting for
examination by any stockholder.

REVOKE IT AT ANY TIME PRIOR TO ITS USE BY DELIVERING A WRITTEN NOTICE TO THE
SECRETARY OF AVS, BY EXECUTING A LATER-DATED PROXY OR BY ATTENDING THE MEETING
AND VOTING IN PERSON. UNLESS AUTHORITY IS WITHHELD, PROXIES WHICH ARE PROPERLY
EXECUTED WILL BE VOTED FOR THE PURPOSES SET FORTH THEREON.

                                  THE MEETING


DATE, TIME, PLACE AND PURPOSE


     This proxy statement and the accompanying form of proxy are being
furnished to holders of AVS Common Stock in connection with the solicitation of
proxies by the AVS Board for use at the Meeting to be held on         , 1998,
at                  , Florida, commencing at 10:00 a.m. local time, and at any
adjournment or postponement thereof. The Meeting is being held for the purposes
set forth in foregoing Notice of Annual Meeting of Stockholders.


VOTING RIGHTS; VOTE REQUIRED FOR APPROVAL


     The AVS Board has fixed the close of business on         , 1998, as the
Record Date for the determination of the AVS stockholders entitled to notice of
and to vote at the Meeting. Accordingly, only holders of record of shares of
AVS Common Stock at the close of business on the Record Date will be entitled
to notice of, and to vote at, the Meeting. At the close of business on the
Record Date, there were       shares of AVS Common Stock outstanding and
entitled to vote, held by       holders of record. Each holder of record of
shares of AVS Common Stock on the Record Date is entitled to cast one vote per
share on each proposal properly submitted for the vote of the AVS stockholders,
either in person or by properly executed proxy, at the Meeting. Pursuant to the
Delaware General Corporation Law ("DGCL"), the AVS Charter and AVS's Bylaws,
the presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of AVS Common Stock on the Record Date is
necessary to constitute a quorum at the Meeting. Abstentions will be counted in
determining whether a quorum is present.


     Approval and adoption of the Merger Proposal, the approval of the election
of the two nominees as directors of AVS and the ratification of the selection
of AVS's auditors requires the affirmative vote of a majority of the
outstanding shares of AVS Common Stock issued and outstanding on the Record
Date in attendance at the Meeting, either in person or by proxy. Abstentions
will have the same effect as negative votes.


     Pursuant to a Voting Agreement and Irrevocable Proxy, dated as of March
26, 1998, by and among Whitehall, Robert Alpert, RCP Management L.P. ("RCP"),
AVAC Corporation ("AVAC"), Dale S. Baker and Harold M. Woody (the "AVS Voting
Agreement"), which is attached as Annex C to this proxy statement, each of RCP,
AVAC and Messrs. Alpert, Baker and Woody, who together own in the aggregate
      shares of AVS Common Stock or approximately 30% of the AVS Common Stock
outstanding on the Record Date, have agreed to vote their shares of AVS Common
Stock (or cause them to be voted) in favor of adoption and approval of the
Merger Proposal.


     Directors, executive officers and principal stockholders of AVS who
collectively own of record         shares of AVS Common Stock representing
approximately     % of the total voting power of the shares of AVS Common Stock
outstanding on the Record Date (including the shares described above) have
indicated their intention to vote in favor of the Merger Proposal, the election
of the two nominees as directors of AVS and the ratification of the selection
of AVS's independent auditors.


VOTING AND REVOCATION OF PROXIES


     Shares of AVS Common Stock represented by properly executed proxies
received at or prior to the Meeting and not revoked will be voted in the manner
specified on such proxies; however, properly executed proxies marked "abstain,"
or which are marked to deny discretionary authority, although counted for
purposes of determining whether there is a quorum at the Meeting, will not be
voted. Properly executed proxies which do not contain voting instructions will
be voted FOR approval and adoption of the Merger Proposal, the election of the
two nominees as directors of AVS and the ratification of the selection of AVS's
auditors. Under applicable New York Stock Exchange ("NYSE") rules, brokers will
not be permitted to submit proxies authorizing a vote on a proposal in the
absence of


                                       1
<PAGE>

specific instructions from beneficial owners. Broker non-votes and abstentions
will have the effect of votes against the adoption and approval of a proposal.
Under Delaware law, both abstentions and broker non-votes contained on a
returned proxy card will be considered present for purposes of determining the
existence of a quorum at the Meeting.


     At the date of this proxy statement, the AVS Board does not know of any
business to be presented at the Meeting other than as set forth in the notice
accompanying this Proxy Statement. If any other matters should properly be
presented at the Meeting for consideration, including, among other things,
consideration of a motion to adjourn the Meeting to another time and/or place,
the persons named in the enclosed form of proxy and acting thereunder will have
discretion to vote on such matters in accordance with their best judgment.


     A stockholder may revoke his or her proxy at any time prior to its use by
(i) delivering to the Secretary of AVS a signed notice of revocation bearing a
later date than the proxy, or a duly executed later-dated proxy relating to the
same shares or (ii) attending the Meeting and voting in person. Attendance at
the Meeting will not in itself constitute the revocation of a proxy. Any
written notice of revocation or subsequent proxy should be sent so as to be
delivered to AVS at 6905 N.W. 25th Street, Miami, Florida 33122, Attention:
Secretary, or hand-delivered to the Secretary of AVS at the aforementioned
address at or before the taking of the vote at the Meeting.


SOLICITATION OF PROXIES


     Costs and expenses incurred in connection with the printing and mailing of
this proxy statement will be paid by AVS. In addition to solicitation by mail,
proxies may be solicited by directors, officers and employees of AVS in person
or by telephone, telegram or other means of communication. Such directors,
officers and employees will receive no additional compensation for such
services, but may be reimbursed for reasonable out-of-pocket expenses in
connection with such solicitation. Custodians, nominees and fiduciaries will be
requested to forward proxy solicitation materials to the beneficial owners of
shares held of record by them, and will be reimbursed for the reasonable
expenses incurred by them in connection therewith.


APPRAISAL RIGHTS


     Under Delaware law, the holders of shares of AVS Common Stock are not
entitled to any appraisal rights in connection with Proposal Nos. 1, 2 or 3.

                                 RISK FACTORS


     IN ADDITION TO THE OTHER INFORMATION IN THIS PROXY STATEMENT, THE
FOLLOWING FACTORS SHOULD BE CONSIDERED CAREFULLY BY HOLDERS OF AVS COMMON STOCK
IN EVALUATING WHETHER TO APPROVE AND ADOPT THE MERGER PROPOSAL.


FIXED EXCHANGE RATIO


     The Merger Agreement provides for the conversion and exchange of each
outstanding share of Whitehall Common Stock into the right to receive .5143
shares of AVS Common Stock (the "Exchange Ratio"). The Exchange Ratio is fixed
and will not be adjusted in the event of any increase or decrease in the
relative or respective stock prices of AVS Common Stock and Whitehall Common
Stock. The relative and respective prices of AVS Common Stock and the Whitehall
Common Stock at the Effective Time may vary from the prices as of the date the
Merger Agreement was approved by the respective Boards of Directors of AVS and
Whitehall, the date that the SBC Warburg Dillon Read opinion letter ("SBCWDR
Opinion") was rendered, or the date that the Merger contemplated by the Merger
Agreement (the "Merger") is consummated, due to changes in the business
operations and prospects of AVS or Whitehall, market assessments of the
likelihood that the Merger will be consummated, and the timing thereof, general
market and economic conditions, and other factors.


UNCERTAINTIES IN INTEGRATION OF THE BUSINESS


     The Merger involves the integration of two companies that have previously
operated independently. There can be no assurance that AVS and Whitehall will
not encounter difficulties in integrating the operations of the two companies
or that the benefits expected from such integration will be realized. Any
delays or unexpected costs incurred in connection with such integration could
have a material adverse effect on the combined company's business, operating
results or financial condition. Furthermore, there can be no assurance that the
operations, managements and personnel of the two companies will be compatible
or that AVS or Whitehall will not experience the loss of key personnel.


SIGNIFICANT LEVERAGE


     As of March 31, 1998, Whitehall had outstanding indebtedness of $16.8
million. As of March 31, 1998 AVS had outstanding indebtedness of $203.3
million, of which $25.2 million is indebtedness under its Third Amended Credit
Agreement dated October 17, 1997 with certain financial institutions (the
"Credit Facility"), and $164.0 million is AVS's senior subordinated 81/8% notes
due 2008 (the "Notes"). See "AVS's Management's Discussion--Liquidity and
Capital Resources." As of April 28, 1998, AVS had availability under the Credit
Facility of $56.8 million. The Credit Facility is secured by substantially all
of the assets of AVS. Subject to certain limitations in the documents governing
its indebtedness, AVS may be able to incur additional amounts of secured
indebtedness. AVS's ability to make payments of principal and interest on, or
to refinance its indebtedness (including the Notes), depends on its future
operating performance, which to a certain extent is subject to economic,
financial, competitive and other factors beyond its control. The degree to
which AVS is leveraged could have important consequences to holders of AVS
Common Stock, including (i) AVS's vulnerability to adverse general economic and
industry conditions, (ii) AVS's ability to obtain additional financing for
future working capital expenditures, general corporate purposes or other
purposes and (iii) the dedication of a substantial portion of AVS's cash flow
from operations to the payment of principal and interest on indebtedness,
thereby reducing the funds available for operations and future business
opportunities. AVS's debt service requirement for 1998 is approximately $28.6
million.


POSSIBLE DEPRESSING EFFECT OF FUTURE SALES OF COMMON STOCK


     Future sales of shares of AVS Common Stock by the holders of the 3,101,229
shares of AVS Common Stock to be issued in connection with the Merger,
including the shares to be issued upon exercise of the Whitehall Options (the
"Merger Shares"), or the perception that such sales could occur,


                                       3
<PAGE>

could adversely affect the market price of the AVS Common Stock. Upon
consummation of the Merger and assuming the exercise of the Whitehall Options
in full at such time, AVS will have 12,694,789 shares of AVS Common Stock
outstanding.


     In connection with the Merger, AVS has agreed to register the Merger
Shares under the Securities Act of 1933, as amended (the "Securities Act")
pursuant to a registration statement on Form S-4, (File No. 333-51479). Also,
AVS has agreed to register for resale shares of AVS Common Stock issuable in
connection with the Merger to affiliates of Whitehall. See "Proposal No.
1--Approval of the Merger Proposal--Other Matters." In addition, AVS has an
obligation to include approximately 257,150 shares of AVS Common Stock issuable
upon the exercise of existing Whitehall options in a registration statement on
Form S-8.


DILUTION


     The issuance of the Merger Shares will have a dilutive effect on earnings
per share and will have a dilutive effect on the voting rights of the holders
of AVS Common Stock as of the Record Date.


POTENTIAL INFLUENCE BY CERTAIN STOCKHOLDERS


     As of the date of this proxy statement, one of AVS's stockholders
beneficially owns 24.6% of the outstanding AVS Common Stock (assuming 2,844,079
shares of AVS Common Stock are issued in the Merger to the current holders of
outstanding shares of Whitehall Common Stock, such stockholder would
beneficially own 19.0% of the combined company immediately following the
Merger), and AVS's directors and executive officers, as a group, beneficially
own an aggregate of 32.8% (including the 24.6% referred to above) of the
outstanding AVS Common Stock (assuming 2,844,079 shares of AVS Common Stock are
issued in the Merger to the current holders of outstanding shares of Whitehall
Common Stock, such stockholders, as a group, would beneficially own 25.4% of
the combined company immediately following the Merger). While each of these
stockholders is an independent party, if these parties were to act together as
a group, they would have the ability to exercise substantial influence on the
election of all of the members of the AVS Board and, therefore, to exercise
substantial influence over the business, policies and affairs of AVS. See
"AVS's Security Ownership of Certain Beneficial Owners and Management."


CLOSING


     The closing of the Merger is subject to the conditions contained in the
Merger Agreement. See "The Merger Agreement--Conditions to the Merger." Many of
these conditions are beyond the control of AVS and Whitehall. Although AVS and
Whitehall believe that such conditions will be fully satisfied, there can be no
assurance that the closing of the Merger will occur. The Closing is subject to
the satisfaction of certain significant conditions, including, among others,
approval by the stockholders of Whitehall and AVS, the receipt by AVS and
Whitehall of an opinion from their independent public accountants with respect
to certain matters relating to the availability of pooling of interests
accounting treatment for the Merger, and the absence of any material adverse
change in the business results of operations or financial condition or
prospects of either AVS or Whitehall. In addition, the Merger Agreement may be
terminated by either party if the closing does not occur by September 30, 1998.

THE MERGER


     Pursuant to the Merger Agreement, upon consummation of the Merger, Sub
will merge with and into Whitehall, with Whitehall being the surviving
corporation (the "Surviving Corporation"). As a result of the Merger, Whitehall
will become a wholly-owned subsidiary of AVS. The Merger will become effective
upon the filing with the Delaware Secretary of State of a Certificate of Merger
(the


                                       5
<PAGE>

"Certificate of Merger") in accordance with the applicable provisions of the
DGCL, or at such later time as may be agreed to by AVS and Whitehall and
specified in the Certificate of Merger. Such filing is expected to take place
on the date of the closing of the transactions contemplated by the Merger
Agreement. The date on which the closing of the transactions contemplated by
the Merger Agreement takes place, which, unless otherwise agreed among the
parties, shall be on the date on which the last of the conditions precedent to
the Merger set forth in the Merger Agreement (other than the filing of the
Certificate of Merger and other than any such conditions which by their terms
are not capable of being satisfied prior to such date) is satisfied or, when
permissible, waived, is herein called the "Closing Date." See "The Merger
Agreement--Effective Time; Effect of the Merger."


MERGER CONSIDERATION


     Pursuant to the Merger Agreement, at the Effective Time, each share of
Whitehall Common Stock outstanding immediately prior to the Effective Time will
be converted into the right to receive, and will be exchangeable for, .5143
shares of AVS Common Stock. Fractional shares of AVS Common Stock will not be
issued in the Merger and holders of Whitehall Common Stock otherwise entitled
to a fractional shares of AVS Common Stock will receive an amount in cash equal
to the same fraction of the current market value of a whole share of AVS Common
Stock determined as described herein. "The Merger Agreement--Conversion of
Shares." For a description of the AVS Common Stock to be issued in the Merger,
see "Description of AVS Capital Stock--AVS Common Stock."


     At the Effective Time, outstanding options to purchase shares of Whitehall
Common Stock (collectively, "Whitehall Options") will be converted into the
right to purchase that number of shares of AVS Common Stock as the holder of
such options would have been entitled to receive had they exercised such
options prior to the consummation of the Merger and participated in the Merger.
As of April 29, 1998, there were outstanding options to purchase 500,000 shares
of Whitehall Common Stock. Additionally, options to purchase shares of
Whitehall Common Stock granted pursuant to Whitehall's 1992 Incentive Stock
Option Plan (which will be converted into options to purchase shares of AVS
Common Stock, as described above) will, in accordance with the terms of such
plans, immediately vest upon consummation of the Merger. All other Whitehall
Options will continue to vest in accordance with the vesting schedules
contained in the agreements evidencing such Whitehall Options.


BACKGROUND OF THE MERGER


     The terms and conditions of the Merger Proposal were determined through
arm's-length negotiations between the management and the Boards of Directors of
AVS and Whitehall. In determining the definitive terms of the Merger Agreement,
numerous factors were considered by the Boards of Directors of AVS and
Whitehall. See "Reasons for the Merger" below. The following is a brief
discussion of these negotiations and certain related events.


     During 1997, in connection with its continuing efforts to position itself
for the future, AVS's management and Board made a strategic decision to expand
the services which AVS offers to its customers to include the maintenance,
repair and overhaul ("MRO") of aircraft. AVS believed that the combination of
its worldwide leading aircraft parts redistribution business with a fully
integrated MRO business would provide it with a competitive advantage in the
marketplace. To this end, in September 1997 and March 1998, respectively, AVS
acquired three FAA-licensed repair stations: (i) Aerocell, which specializes in
the MRO of airframe components, including bonded and structural assemblies for
commercial aircraft, (ii) Caribe, which specializes in the MRO of hydraulic,
pneumatic, electrical and electromagnetic aircraft components, as well as
avionics and instruments on Airbus and Boeing aircraft, and (iii) Aircraft
Interior Design, Inc. ("Aircraft"), a wholly-owned subsidiary of Caribe, which
manufactures plastic cabin interior replacement parts under FAA-PMA approval
and refurbishes aircraft interior components.


     In early 1997, management of Whitehall identified certain objectives it
believed would assist Whitehall in achieving its strategic and financial goals.
Among the objectives identified were


                                       6
<PAGE>

(i) reducing Whitehall's dependence on commercial maintenance customers by
selectively pursuing military contracts which have the potential of generating
sustained revenues over several years, (ii) strengthening Whitehall's
relationships with its core customers and developing new relationships with
major commercial airlines, and (iii) identifying and acquiring companies with a
customer base or product line which complements or expands Whitehall's existing
operations. In furtherance of its strategy, in April 1997, Whitehall was
awarded a five-year contract (the "C-130 Contract") by the United States Air
Force (the "USAF") to perform programmed depot maintenance on the USAF's fleet
of C-130 cargo aircraft. In June 1997, the C-130 Contract was canceled by the
U.S. government because the USAF elected to perform this work with government
personnel rather than outsourcing it to private contractors. In July 1997,
Whitehall purchased from Zantop International Airlines, Inc. ("Zantop") certain
assets used in connection with Zantop's third party aircraft maintenance
business located in Macon, Georgia. Throughout 1997 and during the first
quarter of 1998, Whitehall had discussions with several other companies in the
aircraft service industry concerning a possible acquisition or other business
combination, however none of those discussions resulted in any agreement or
transaction.


     During the fall of 1997, in furtherance of AVS's strategy, William H.
Alderman ("Alderman"), AVS's Senior Vice President, Corporate Development,
contacted George F. Baker ("G. Baker"), Whitehall's Chairman of the Board and
Chief Executive Officer and a general partner of Cambridge Capital Fund, L.P.
("Cambridge") and Baker Nye, L.P. ("Baker Nye") (which control approximately
34% of Whitehall's outstanding common stock), to determine whether there was
any interest on Whitehall's part about pursuing a dialogue concerning a
possible amalgamation of the two companies.


     As a result of this initial contact, on December 16, 1997, Dale S. Baker
("D. Baker"), AVS's Chairman, President and CEO, Joseph E. Civiletto
("Civiletto"), AVS's Vice President and CFO, Alderman, G. Baker and Jeffrey N.
Greenblatt ("Greenblatt"), an employee of Whitehall and a general partner of
Cambridge and Baker Nye, met in New York. At this meeting, the parties
discussed generally the aviation industry, the MRO market, their respective
visions of the future of the aviation industry and the current status of their
respective companies. D. Baker expressed an interest to Messrs. G. Baker and
Greenblatt in pursuing a dialogue as to a possible amalgamation of the two
companies.


     As a result of these discussions, in early January 1998, the parties
entered into a confidentiality agreement and exchanged preliminary financial
and other information regarding their respective business activities.


     In late January 1998, Messrs. D. Baker, Civiletto, Alderman, G. Baker,
Greenblatt and John Wilson, Whitehall's President ("Wilson"), met in New York
and further discussed the aviation industry, their respective companies and
what a combined company might look like. Again, no agreements were reached
during these discussions. However, the parties agreed to commence preliminary
due diligence regarding their respective companies. To this end, during
mid-February 1998, D. Baker, Harold Woody, AVS's Executive Vice President,
Civiletto and various other AVS representatives, visited Whitehall's Lake City
and Macon repair facilities and Messrs. G. Baker and Wilson visited AVS's Miami
facility.


     On February 25, 1998, Messrs. G. Baker, D. Baker, Greenblatt and Wilson
met for dinner in New York. At that meeting, the parties agreed that
discussions should be pursued to determine whether an acceptable arrangement
could be reached. While there was general discussion at this meeting regarding
the respective views of the parties as to the terms of a proposed transaction,
no agreements were reached on these issues. The parties did agree, however,
that the form of any such transaction should be a stock-for-stock merger
accounted for on a pooling of interests basis.


     On March 6, 1998, Messrs. G. Baker, Greenblatt, Wilson and Garlan
Braithwaite, Whitehall's Senior Vice President and CFO, met at AVS's Miami
headquarters to discuss the terms of a proposed amalgamation. At that meeting,
a tentative agreement was reached for AVS and Whitehall to merge in a
stock-for-stock transaction accounted for as a pooling of interest. The parties
agreed on an exchange ratio that could form the basis of a definitive agreement
but was subject to continued legal and business due diligence. No decision was
made as to other terms of the Merger Agreement. The parties also


                                       7
<PAGE>

expressed their desire for the principal stockholders of both entities to enter
into voting agreements and irrevocable proxies to vote their respective shares
of AVS Common Stock and Whitehall Common Stock in favor of the merger at
stockholders meetings to be called for that purpose.


     Between March 7, 1998 and March 10, 1998, representatives of AVS and
Whitehall and their respective legal, financial and accounting advisors
participated in discussions in which the terms of the Merger Agreement were
negotiated and legal and business information concerning the companies was
exchanged. During this time, management of Whitehall engaged Ladenburg Thalmann
& Co., Inc. ("Ladenburg") to assist the Whitehall Board of Directors
("Whitehall Board") in analyzing the fairness of the proposed exchange ratio to
the holders of Whitehall Common Stock. Mr. G. Baker also telephoned members of
the Whitehall Board to advise them of a possible transaction with AVS.


     On March 13, 1998, the Whitehall Board met by telephone conference to
review, among other things, the potential combination with AVS and the terms
thereof. At this meeting, representatives of Baker & Botts, L.L.P. ("Baker &
Botts"), Whitehall's legal counsel, summarized issues relating to the proposed
merger and the fiduciary duties of the Whitehall Board in connection therewith.
Representatives of Ladenburg also provided to the Whitehall Board a preliminary
review of the proposed merger from a financial point of view and provided an
oral opinion that the proposed exchange ratio was fair, from a financial point
of view, to the stockholders of Whitehall. The Whitehall Board authorized
management to go forward with the negotiations.


     Between March 15, 1998 and March 22, 1998, representatives of AVS and
Whitehall, and their legal counsel, met continually to conduct due diligence,
to negotiate the terms of the Merger and to prepare a definitive agreement and
plan of merger with respect to the proposed transaction.


     In connection with AVS's due diligence investigation, Whitehall presented
AVS with various financial projections regarding its future business. AVS's
management took a more conservative view of these projections than was taken by
Whitehall's management. Further, in connection with its due diligence
investigation, AVS determined that it believed that for the 1997 fiscal year,
Whitehall would need to significantly increase its reserves for environmental
remediation and write-down the value of certain inventory, due to items which
it had reviewed while completing its diligence investigation on Whitehall.


     As a result of all of these factors, AVS's and Whitehall's management
teams met at AVS's Miami headquarters on March 22, 1998 to further discuss the
proposed transaction. At that meeting, and based upon these factors, AVS
revised its offer downward. AVS's revised proposal was that it would acquire
all of the outstanding shares of Whitehall Common Stock on a share for share
exchange ratio of .5143 shares of AVS Common Stock for each share of Whitehall
Common Stock outstanding. Whitehall's management team agreed to consider the
revised proposal.


     On March 24, 1998, the Whitehall Board held a special meeting to review
AVS's revised proposal and the proposed Merger. Representatives of Baker &
Botts discussed with the Whitehall Board the terms of the Merger Agreement.
Representatives of Ladenburg also provided to the Whitehall Board a review of
the proposed Merger from a financial point of view and provided an oral opinion
that the revised exchange ratio of .5143 shares of AVS Common Stock for each
share of Whitehall Common Stock was fair, from a financial point of view, to
the stockholders of Whitehall. The expected business synergies, consolidation
benefits and various other qualitative aspects of the proposed merger were also
discussed. Messrs. Wilson and Braithwaite also discussed with the Whitehall
Board Whitehall's preliminary financial results for 1997. At that point, the
Whitehall Board voted to adjourn the meeting until the following evening when
it expected to have the final 1997 financial results and the report of Arthur
Andersen, L.L.P. ("Arthur Andersen"), Whitehall's independent auditors. Prior
to adjourning the meeting, the Whitehall Board agreed in principle to the terms
of the Merger Agreement but determined to postpone a formal vote thereon until
the meeting was reconvened.


     On March 25, 1998, the meeting of the Whitehall Board was reconvened by
telephone conference. Messrs. Wilson and Braithwaite reported that Arthur
Andersen was prepared to issue an unqualified


                                       8
<PAGE>

report on Whitehall's 1997 financial statements in substantially the form
outlined for the Whitehall Board the previous evening. After discussion of the
final terms of the Merger and the Merger Agreement and after having received
notice that the AVS Board had unanimously approved the Merger and the Merger
Agreement earlier that day, the Whitehall Board unanimously approved the Merger
and the Merger Agreement and approved a resolution recommending that the Merger
Agreement be submitted to Whitehall's stockholders for their approval. Further,
at a meeting held on March 25, 1998, the AVS Board, after receiving an opinion
from SBCWDR that as of that date the Exchange Ratio is fair to AVS's
shareholders from a financial point of view, approved the Merger Agreement.


     The final negotiations on the Merger Agreement and the exhibits thereto
took place on March 24, 1998 and March 25, 1998, and the Merger Agreement, the
Whitehall Voting Agreement and the AVS Voting Agreement were executed and
delivered early in the morning on March 26, 1998. A press release announcing
the Merger was disseminated before the opening of business on March 26, 1998.


JOINT REASONS FOR THE MERGER


     Based upon their respective experiences and their internal analysis of the
current environment of the aviation and MRO industries, AVS's and Whitehall's
Board of Directors have concluded that the combination of AVS with Whitehall
creates a fully integrated participant in both the worldwide aviation MRO
business and the aviation parts market. In reaching their conclusions, the
respective Boards of the two companies were aware that the combination of AVS,
with its leading market position in aircraft parts redistribution and its
previously acquired MRO's and aircraft parts manufacturing capacity, with
Whitehall, with its two FAA-licensed repair stations specializing in heavy
maintenance of aircraft, would create a more formidable competitor in the
market and should allow the combined entity to offer parts, inventory
management services and repair services to the same airline customers on an
integrated basis, making the combined entity more competitive in the market.


AVS REASONS FOR THE MERGER


     At a meeting held on March 25, 1998, the AVS Board determined that the
Merger was fair to AVS's stockholders from a financial point of view and
approved the Merger Agreement. In reaching its conclusions, the AVS Board
considered the following factors, as well as the reasons set forth above:


      1. The effects on its future estimated earnings per share due to the
acquisition of Whitehall and whether such transaction would be accretive or
dilutive to AVS's stockholders. AVS believes that the combination of the
businesses and the elimination of certain costs will allow AVS to expand its
presence in the MRO industry and enable AVS to achieve significant increases in
its earnings per share in 1999 and subsequent years.


      2. The Merger will create a combined entity that should help AVS achieve
the strategic goals which it has established, to benefit from the anticipated
trends in the MRO and aircraft parts business and should allow the combined
entity to have significant growth opportunities after consummation of the
Merger. In that regard, AVS Board and AVS management believe that: (a) AVS's
ability to provide parts support will enable AVS's repair operations, including
Whitehall, to avoid delays often encountered in the MRO industry due to parts
shortages; (b) AVS will enjoy a cost advantage based upon the costs associated
with Whitehall's Lake City operation compared to the cost structures of many of
Whitehall's competitors; (c) by focusing on "turn time" and quality, and by
cross selling its MRO services to its existing airline customers, AVS can
substantially increase Whitehall's business; and (d) Whitehall's recent capital
expenditures program to enhance its Lake City facilities will allow AVS to
support significant additional growth in revenues without significant
additional capital costs.


      3. The Merger will be deleveraging to AVS, in that AVS will add
substantial stockholder equity without adding significant additional debt.


      4. The terms and conditions of the Merger, the Merger Agreement and
related matters. In considering the terms of the Merger, particular attention
was given by the AVS Board to: (a) the


                                       9
<PAGE>

consideration to be received by Whitehall's stockholders and (b) the
termination provisions, including the potential payment by Whitehall of a $7.5
million termination fee, in the event that the Whitehall Board recommends a
Superior Proposal and AVS terminates the Merger Agreement and, within one year
Whitehall enters into a Superior Proposal. The AVS Board also considered the
treatment of outstanding options to purchase shares of AVS Common Stock. In
addition, the AVS Board considered the terms of the Merger Agreement as a whole
(and not individually) and, given its experience in similar transactions and
analysis of comparable transactions, determined to approve the Merger and adopt
the Merger Agreement.


      5. Current market conditions, historical market prices and trading
information for both AVS and Whitehall.


      6. The historical and current financial conditions, results of
operations, prospects and businesses of AVS and Whitehall before and after
giving effect to the Merger.


      7. The opinion of SBCWDR that as of the date of its opinion the Exchange
Ratio is fair, from a financial point of view, to AVS's stockholders.


      8. The AVS Board also considered: (i) the potential for increases in
operating efficiencies for the combined company, (ii) the ability for AVS to
obtain additional sales through sales of parts to Whitehall to be used in
connection with services offered to customers of Whitehall, as well as to
further leverage the existing services of AVS's other MRO operations by
providing ancillary repair services required by Whitehall in connection with
their providing heavy maintenance of aircraft to their customers, and (iii) the
ability of AVS after the Merger to provide "nose to tail" MRO and inventory
management solutions to its airline customers, allowing AVS to more fully meet
the inventory and MRO requirements of its customers. The AVS Board was also
aware of the substantial consolidation which is ongoing in the MRO business and
concluded that large, well capitalized entities will have better opportunities
in the MRO market in the future.


     The AVS Board believes that the Merger will not change the nature of the
business in which stockholders have invested, but will provide for that
investment to be in a larger, more competitive, more efficient enterprise.


     In reaching its conclusions on the Merger, the AVS Board also considered a
number of potentially negative factors in its deliberations, including (a) the
charges typically expected to be incurred in connection with the Merger,
primarily in the fiscal quarter in which the Merger closes; (b) the risk that
the aggregate consideration to be paid by AVS to acquire Whitehall may exceed
the amount of consideration justified based upon the current earnings level of
Whitehall or based upon the future performance of Whitehall; (c) the fact that
AVS may not terminate the Merger Agreement due solely to fluctuations in the
market price of Whitehall Common Stock or AVS Common Stock; (d) the risk that
the market price of AVS Common Stock may be adversely affected by the public
announcement of the Merger; (e) the risks involved in the integration of the
two companies, and the risks that the perceived benefits of the Merger will not
be realized; (f) the risks arising from disruption of Whitehall's business or
employee base due to the uncertainties which may arise after the Merger is
announced or during the period after the Merger is consummated but before the
operations of AVS and Whitehall have been combined; (g) the risks associated
with the possibility of material adverse changes in Whitehall's business; and
(h) the possibility that the Merger might not be consummated and the
corresponding potential adverse effect of such a result on the market price of
AVS Common Stock. In the view of the AVS Board these considerations were not
sufficient, either individually or collectively, to outweigh the potential
advantages of the Merger.


     In view of a wide variety of factors, both positive and negative,
considered by the AVS Board, the AVS Board did not find it practicable to
quantify or otherwise assign relative weights to the specific factors
considered. Rather, the AVS Board viewed its determination and recommendations
as being based on the totality of the information presented to it and
considered by it. Individual members of the AVS Board may have given different
weight to different factors.

INTERESTS OF CERTAIN PERSONS IN THE MERGER


     In considering the recommendation of the AVS Board with respect to the
Merger, AVS stockholders should be aware that certain members of AVS's
management and the AVS Board have certain interests in the Merger in addition
to the interests of AVS's stockholders generally. The AVS Board was aware of
these interests and considered them among other matters, in approving the
Merger Agreement.


     VOTING AGREEMENTS. In connection with the Merger Agreement, certain
stockholders of AVS, owning in the aggregate approximately 30% of the
outstanding shares of AVS Common Stock, have entered the AVS Voting Agreement
and certain stockholders of Whitehall, owning in the aggregate approximately
34% of the outstanding shares of Whitehall Common Stock, have entered into the
Whitehall Voting Agreement and Irrevocable Proxy with AVS ("Whitehall Voting
Agreement").


     Pursuant to the AVS Voting Agreement, and for so long as it remains in
effect, Robert Alpert, RCP and AVAC, Dale S. Baker and Harold M. Woody have
agreed to vote their shares of AVS Common Stock, and have given AVS an
irrevocable proxy to Whitehall to vote their shares of AVS Common Stock, (i) in
favor of the adoption and approval of the Merger Agreement and the Merger at
every meeting of AVS stockholders where such matter is considered and (ii)
against any actions or approval that would compete with or could serve to
materially interfere with, delay, discourage, adversely affect or inhibit the
timely consummation of the Merger. Robert Alpert is a director of AVS and
beneficially owns the shares of AVS Common Stock owned by RCP and AVAC. Dale S.
Baker is the Chairman of the Board, President and Chief Executive Officer of
AVS and Harold M. Woody is Executive Vice President and a director of AVS.


     Pursuant to the Whitehall Voting Agreement, and for so long as it remains
in effect, each of Cambridge and Baker Nye have agreed to vote their shares of
Whitehall Common Stock, and have given AVS an irrevocable proxy to vote their
shares of Whitehall Common Stock, (i) in favor of the adoption and approval of
the Merger Agreement and the Merger at every meeting of Whitehall stockholders
where such matters are considered and (ii) against any actions or approval that
would compete with or could serve to materially interfere with, delay,
discourage, adversely affect or inhibit the timely consummation of the Merger,
including any Alternative Proposal (as defined in the Merger Agreement). George
F. Baker, the Chairman of the Board and Chief Executive Officer of Whitehall is
a general partner of each of Cambridge and Baker Nye and may be deemed to own
beneficially the 1,893,400 aggregate shares of Whitehall Common Stock owned by
them.


     The foregoing summary of the AVS Voting Agreement and the Whitehall Voting
Agreement is qualified in its entirety by reference to the complete text of
such agreements, which are included as Annex C and D, respectively, to this
proxy statement.


OTHER MATTERS


     APPOINTMENT OF ADDITIONAL DIRECTORS. Under the Merger Agreement, AVS has
agreed that effective immediately following the Effective Time, it will
increase the number of members of the AVS Board from six (6) to eight (8) and
appoint George F. Baker and Jeffrey N. Greenblatt as members of the AVS Board
of Directors to serve for respective terms expiring at the annual meeting of
the AVS stockholders to be held in 2001 and 2000. George F. Baker is the
Chairman of the Board and Chief Executive Officer of Whitehall and a general
partner of Cambridge and of Baker Nye. Jeffrey Greenblatt is an employee of
Whitehall and a general partner of Cambridge and of Baker Nye.


     REGISTRATION RIGHTS. As a condition to Whitehall's obligation to
consummate the Merger, AVS has agreed to enter into prior to the Effective
Time, a registration rights agreement ("Registration Rights Agreement") with
certain persons. Pursuant to the Registration Rights Agreement, AVS has agreed
to (i) prepare and file with the Commission within thirty days from Closing
Date a registration statement for the offering and sale, on a delayed or
continuous basis, shares of AVS Common Stock issued to such


                                       11
<PAGE>

persons pursuant to the Merger Agreement and (ii) grant, in certain situations,
demand and "piggyback" registration rights for such shares. In addition to AVS,
the parties to the Registration Rights Agreement are Cambridge, Baker Nye,
George F. Baker, the Chairman of the Board and Chief Executive Officer of
Whitehall and a general partner of Cambridge and Baker Nye, John H. Wilson, the
President and a director of Whitehall, Bruce R. Conway, the Secretary and a
director of Whitehall, and Arthur R. Hutton, John J. McAttee, Jr., Jack S.
Parker and Lewis S. White each of whom are directors of Whitehall.


     ACCELERATION OF OPTIONS. At the Effective Time, outstanding Whitehall
Options will be converted into the right to purchase that number of shares of
AVS Common Stock as the holder of such would have been entitled to receive had
they exercised such Whitehall Options prior to consummation of the Merger and
participated in the Merger. Whitehall Options issued pursuant to AVS's 1992
Incentive Stock Option Plan (which will be converted into options to purchase
shares of AVS Common Stock, as described above), will, in accordance with the
terms of the plans and such agreements, immediately vest at the closing of the
Merger. All other Whitehall Options will continue to vest in accordance with
the vesting schedules contained in the agreements evidencing such Whitehall
Options.


INDEMNIFICATION OF OFFICERS AND DIRECTORS


     After the Effective Time, AVS agreed to, and agreed to cause the Surviving
Corporation to, indemnify and hold harmless each person who is, as of March 26,
1998, or has been at any time prior to such date or who becomes prior to the
Effective Time, an officer, director, employee or agent of Whitehall and its
subsidiaries (each an "Indemnified Person"), from and against all losses,
reasonable expenses (including reasonable attorneys' fees), claims, damages,
liabilities or amounts paid in settlement of, or otherwise in connection with
any threatened or actual claim, action, suit, proceeding or investigation,
based in whole or in part on or arising in whole or in part out of the fact
that the Indemnified Person (or person controlled by the Indemnified Person) is
or was an officer, director, employee or agent of Whitehall or its subsidiaries
and pertaining to any matter existing or arising out of actions or omissions
occurring at or prior to the Effective Time to the extent permitted under DGCL.
 


CERTAIN FEDERAL INCOME TAX CONSEQUENCES


     AVS believes that the transactions contemplated by the Merger Proposal
represent a nontaxable event for AVS within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code").


FEDERAL SECURITIES LAWS CONSEQUENCES


     The shares of AVS Common Stock to be received by Whitehall's stockholders
in connection with the Merger are to be registered under the Securities Act.
Accordingly, there will be no restrictions upon the resale or transfer of such
shares by Whitehall's stockholders, except for those stockholders who are
deemed to be "affiliates" of Whitehall as such term is defined in Rule 144
under the Securities Act.


     With respect to those stockholders who may be deemed to be "affiliates" of
Whitehall, Rule 144 and Rule 145 place certain restrictions on the transfer of
the shares of AVS Common Stock which may be received by them pursuant to the
Merger. Persons who may be deemed to be "affiliates" of Whitehall generally
include individuals who, or entities which, directly or indirectly, control or
are controlled by or are under common control with Whitehall and may include
certain officers and directors of Whitehall as well as principal stockholders
of Whitehall. AVS has agreed to register such shares of AVS Common Stock for
resale or transfer by such "affiliates" of Whitehall. See "Other
Matters--Registration Rights." Additionally, it is a condition to the
consummation of the Merger that all persons deemed "affiliates" of Whitehall
enter into an agreement whereby each such person agrees, among other things,
not to sell their shares of AVS Common Stock received by them in connection
with the Merger until combined operating results covering a minimum thirty day
period of AVS and Whitehall are publicly released.

REGULATORY APPROVAL


     Certain acquisitions such as the Merger are reviewed by the Antitrust
Division of the Department of Justice (the "Antitrust Division") or the Federal
Trade Commission (the "FTC") to determine whether such transactions comply with
applicable antitrust laws. Under the provisions of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HRS Act"), the Merger
could not be consummated until notifications had been given and certain
information had been furnished to the FTC and the Antitrust Division and
certain waiting period requirements of the HSR Act had been satisfied.
Information and material required under the HSR Act was filed with the
Antitrust Division and the FTC by AVS and Whitehall on April 13, 1998. AVS and
Whitehall were notified that early termination of the waiting period applicable
to the acquisition of the Whitehall Common Stock by AVS in the Merger was
granted on April 27, 1998. Notwithstanding such early termination, at any time
before or after consummation of the Merger, the FTC or the Antitrust Division
could take such action under the antitrust laws as they deem necessary or
desirable in the public interest, including seeking to enjoin the consummation
of the Merger or seeking divestiture of substantial assets of AVS or Whitehall.
At any time before or after the Effective Date, and notwithstanding that the
HSR Act waiting period has been terminated, any state having appropriate
jurisdiction could take such action under the antitrust laws as it deems
necessary or desirable. Such action could include seeking to enjoin the
consummation of the Merger or seeking divestiture by AVS of Whitehall or
certain of the businesses of AVS or Whitehall. Private parties may also seek to
take legal action under antitrust laws under certain circumstances. In
addition, holders of Whitehall Common Stock who, pursuant to the Merger, will
be acquiring shares of AVS Common Stock having a value of more than $15 million
or a value which, when aggregated with the value of shares of AVS Common Stock
owned by such persons prior to the Merger, exceeds $15 million, may be subject
to the notification and waiting period requirements of the HSR Act. All such
waiting periods would have to expire or be terminated before any issuance of
shares of AVS Common Stock to those particular stockholders in the Merger could
be effected.


     AVS and Whitehall are aware of no other governmental or regulatory
approvals required for consummation of the Merger, other than compliance with
applicable securities laws of the various states.


ACCOUNTING TREATMENT


     The Merger is intended to qualify as a "pooling of interests" for
accounting and financial reporting purposes.


     Under this method of accounting, the assets and liabilities of AVS and
Whitehall will be combined based on the respective carrying values of the
accounts in the historical financial statements of each entity. Results of
operations of the combined company will include income of AVS and Whitehall for
the entire fiscal period in which the combination occurs and the historical
results of operations of the separate companies for fiscal years prior to the
Merger will be combined and reported as the results of operations of the
combined company.


NYSE LISTING; TERMINATION OF EXCHANGE ACT REGISTRATION


     As a condition to the closing of the Merger, the shares of AVS Common
Stock to be issued upon consummation of the Merger and the shares reserved for
issuance in connection with AVS's stock option plans will be approved for
listing on the NYSE, subject to official notice of issuance.


     Following completion of the Merger, it is expected that the Whitehall
Common Stock will cease being traded on the NYSE and that Whitehall's
registration under the Securities Exchange Act of 1934, as amended (the
"Exchange Act") will be terminated. Accordingly, Whitehall will no longer be
required to file periodic reports with the Commission.


                                       13

ABSENCE OF APPRAISAL RIGHTS


     Delaware law does not require that holders of AVS Common Stock who object
to the Merger Proposal and who vote against or abstain from voting in favor of
the Merger Proposal be afforded any appraisal rights.


OPINION OF AVS'S FINANCIAL ADVISOR


     The AVS Board retained SBCWDR to act as its financial advisor for the
purpose of providing an opinion as to the fairness of the Exchange Ratio from a
financial point of view.


     On March 25, 1998 SBCWDR delivered its oral opinion to the AVS Board,
which opinion was subsequently confirmed in a written opinion dated March 26,
1998 to the effect that, and based upon and subject to the assumptions,
limitations and qualifications set forth therein, as of the date of such
opinion, the Exchange Ratio was fair to the holders of AVS Common Stock from a
financial point of view.


     THE FULL TEXT OF THE WRITTEN OPINION OF SBCWDR, DATED MARCH 26, 1998,
WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE
REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED HERETO AS ANNEX B
TO THIS PROXY STATEMENT AND IS INCORPORATED HEREIN BY REFERENCE. AVS's
stockholders should read such opinion in its entirety. SBCWDR's opinion is
directed only to the Exchange Ratio and does not constitute a recommendation to
any AVS stockholder as to how such stockholder should vote at any meeting of
the AVS stockholders called to approve and adopt the Merger Agreement and the
Merger. The summary of the opinion of SBCWDR set forth in this proxy statement
is qualified in its entirety by reference to the full text of such opinion.


     In arriving at its opinion, SBCWDR, among other things: (i) reviewed
certain publicly available business and historical financial information
relating to AVS and Whitehall, (ii) reviewed certain internal financial
information and other data relating to the business and prospects of AVS,
including financial estimates, that were provided to it by AVS and are not
publicly available, (iii) reviewed certain internal financial information and
other data relating to the business and prospects of AVS, including financial
estimates, provided by the management of AVS, that were provided to it by the
management of AVS and are not publicly available, (iv) conducted discussions
with members of the senior management of AVS and Whitehall with respect to the
operations, financial condition, history, and prospects of each company, (v)
reviewed the historical market prices and trading activity of the common stocks
of AVS and Whitehall, (vi) considered certain pro forma effects of the Merger
on the financial results of AVS (including the effects of assumed combination
savings and synergies that were provided to it by AVS), (vii) reviewed publicly
available financial and stock market data with respect to certain other
companies that SBCWDR believes to be generally comparable to AVS and Whitehall,
(viii) compared the financial terms of the Merger with the financial terms of
certain other transactions that SBCWDR believes to be relevant, (ix) considered
the strategic implications of the Merger as presented to it by management of
AVS, (x) reviewed drafts of the Merger Agreement, and (xi) conducted such other
financial studies, analyses, and investigations, and considered such other
information as it deemed necessary or appropriate. SBCWDR's opinion was
necessarily based on economic, monetary, market, and other conditions as in
effect on, and the information made available to SBCWDR as of, the date
thereof.


     In connection with its review and arriving at its opinion, SBCWDR did not,
with the consent of AVS, assume any responsibility for independent verification
of any of the information reviewed by it for the purpose of this opinion and,
with the consent of AVS, relied on its being complete and accurate in all
material respects. In addition, with the consent of AVS, SBCWDR did not made
any independent evaluation or appraisal of any of the assets or liabilities
(contingent or otherwise) of AVS or Whitehall nor was SBCWDR furnished with any
such evaluation or appraisal. With respect to the financial estimates
(including the effects of assumed Merger savings and synergies) provided to or
otherwise


                                       14
<PAGE>

reviewed by or discussed with it, SBCWDR assumed, with the consent of AVS, that
they have been reasonably prepared, on bases reflecting the best currently
available estimates and judgments of AVS management as to the future financial
performance of each company and that they will be realized in the amounts and
at the times contemplated thereby. At the direction of AVS, SBCWDR assumed that
there will be no material difference between the actual financial results which
will be obtained by AVS, Whitehall or the combined company and those specified
in the estimates, forecasts, and projections provided to it. With respect to
the business and financial information pertaining to Whitehall, SBCWDR did not
hold any independent discussions with Whitehall management as to any aspect of
the information provided. With the consent of AVS, SBCWDR assumed that the
Merger would not result in taxable income for AVS or its stockholders and would
be accounted for as a pooling-of-interests. For the purposes of the opinion,
with the consent of AVS, SBCWDR assumed that the representations and warranties
of each party contained in the Merger Agreement were true and accurate, that
each party would perform all of the covenants and agreements required to be
performed by it under the Merger Agreement, and that all conditions to the
consummation of the Merger would be satisfied without waiver thereof. AVS did
not place any limitations upon SBCWDR regarding the procedures to be followed
and the factors to be considered in rendering its opinion.


     In arriving at its opinion, SBCWDR did not assign any particular weight to
any analysis or factor considered by it, but rather made qualitative judgments
based on its experience in providing such opinions and on the existing
economic, monetary, market, and other conditions as to the significance and
relevance of each analysis and factor. SBCWDR believes that its analyses must
be considered as a whole and that selecting portions of its analyses and other
factors considered by it, without considering all factors and analyses, could
create a misleading or incomplete view of the processes underlying its opinion.
SBCWDR did not quantify the effect of each factor upon its opinion. SBCWDR made
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond AVS's,
Whitehall's and SBCWDR's control. Any assumed estimates contained in SBCWDR's
analyses are not necessarily indicative of actual values or predictive of
future results or values, which may be significantly more or less favorable
than as set forth therein. Estimates of the financial value of companies do not
purport to be appraisals or necessarily reflect the prices at which companies
actually may be sold. Because such estimates inherently are subject to
uncertainty, neither AVS, Whitehall, SBCWDR nor any other person assumes
responsibility for their accuracy. In rendering its opinion, SBCWDR expressed
no view as to the range of values at which the AVS Common Stock may trade
following the consummation of the Merger, nor did SBCWDR make any
recommendations to the AVS stockholders with respect to how such holders should
vote on the Merger.


     In conducting the analyses identified herein, due to certain extraordinary
losses, SBCWDR concluded that certain of these analyses, when based upon 1997
historical information, did not produce meaningful results.


     The following paragraphs summarize the material analyses performed by
SBCWDR in arriving at its opinion.


     ACQUISITION SUMMARY. SBCWDR noted that with an Exchange Ratio of 0.5143
shares of AVS Common Stock per share of AVS Common Stock (or $22.44 per share
of AVS Common Stock) as of March 20, 1998 the Merger would provide for a total
implied equity value of $135.4 million. With the assumption of $10.1 million in
net debt, the Merger would provide for an implied value of assets of $145.5
million. SBCWDR summarized certain acquisition multiples by observing that the
offer for equity as a multiple of net income was 27.0x based upon AVS
management's estimated 1998 income. SBCWDR also noted that the offer for assets
as a multiple of earnings before interest, depreciation, and amortization
("EBITDA") was 17.1x based upon AVS management's estimated 1998 EBITDA, and
13.7x based upon AVS management's estimated 1998 EBITDA inclusive of AVS
management's estimated synergies. The offer for assets as a multiple of
earnings before interest and taxes ("EBIT") was 20.8x based upon AVS
management's estimated 1998 EBIT, and 16.0x based upon AVS management's
estimated 1998 EBIT inclusive of AVS management's estimated synergies.


                                       15
<PAGE>

     PRO FORMA ANALYSIS. SBCWDR prepared pro forma analyses of the financial
impact on AVS of the Merger. A contribution analysis based on AVS management's
estimated fiscal 1998 financial performance showed that on a pro forma basis
for the Merger Whitehall would contribute 23% to the combined stockholders'
equity, 15% to the combined company's net assets, 19% to the combined company's
revenues, 17% to the combined company's EBITDA, 16% to the combined company's
EBIT, and 20% to the combined company's net income. A contribution analysis
based on AVS management's estimated fiscal 1999 financial performance showed
that, on a pro forma basis, for the Merger Whitehall would contribute 22% to
the combined company's stockholders' equity, 10% to the combined company's net
assets, 21% to the combined company's revenues, 17% to the combined company's
EBITDA, 17% to the combined company's EBIT, and 27% to the combined company's
net income, and would receive 24% of the share ownership. Using earnings and
synergies estimates for Whitehall and AVS prepared by AVS management, the
analysis showed that the proposed transaction would be slightly (1.0%) dilutive
to AVS stockholders in fiscal year 1998 and (12.5%) accretive in 1999.


     HISTORICAL STOCK TRADING ANALYSIS. To provide contextual and comparative
market data, SBCWDR examined the history of the trading prices for the shares
of Whitehall Common Stock in relation to AVS and an index of AAR Corp., AVTEAM,
Inc., DeCrane Aircraft Holdings, Inc., Kellstrom Industries, Inc., and Triumph
Group, Inc. (the "Selected Companies") for the last eighteen months. SBCWDR
noted that the Whitehall Common Stock reached a low price of $15.94 per share
on April 15, 1997 and a high price of $23.25 on March 19, 1998 based on weekly
closing stock prices. SBCWDR noted that the Whitehall Common Stock reached a
low price of $19.25 on December 13, 1996 and a high price of $44.25 on March
18, 1998 based on weekly closing stock prices. SBCWDR examined the historical
exchange ratio of Whitehall to AVS shares of common stock and determined that
the Exchange Ratio of 0.5143 was the market Exchange Ratio on March 20, 1998
and was below the historical average over the preceding month of 0.55, below
the historical average over the preceding six months of 0.54, and below the
historical average since January 3, 1997 of 0.71.


     GENERALLY COMPARABLE COMPANY FINANCIAL ANALYSIS. SBCWDR reviewed and
compared certain financial information and ratios for certain aviation services
companies consisting of the Selected Companies which in SBCWDR's judgment were
generally comparable to Whitehall for the purposes of this analysis. No company
in the Selected Companies is identical to Whitehall (including after the
Merger). Accordingly, any analysis of the results of the foregoing is not
mathematical; rather it involves complex considerations and judgments
concerning differences in financial and operating characteristics and other
factors affecting the companies being compared. SBCWDR calculated and compared
various financial multiples and ratios for AVS and each of the Selected
Companies based on the most recent publicly available information. Although
this analysis was performed for Whitehall, Whitehall's information and ratios
were generally not meaningful, due to Whitehall's recent losses, and did not
materially impact SBCWDR's opinion. SBCWDR reviewed and compared certain
financial information relating to AVS to corresponding financial information
and ratios for the Selected Companies. SBCWDR calculated and compared various
financial multiples and ratios for AVS and each of the Selected Companies based
on the most recent publicly available information. Among other things, the
analysis showed that AVS's EBITDA and EBIT margins for the twelve months ended
September 30, 1997 were below the average of the Selected Companies.


     GENERALLY COMPARABLE COMPANY TRADING ANALYSIS. SBCWDR analyzed and
compared certain equity market multiples relating to AVS to corresponding
equity market multiples for the Selected Companies. SBCWDR calculated various
financial multiples for AVS and each of the Selected Companies based on the
most recent publicly available information. This analysis showed that based on
closing stock prices as of March 20, 1998, the Whitehall Common Stock traded
above the average of the Selected Companies. On an equity value basis,
Whitehall traded at 27.0x AVS management's estimated fiscal 1998 earnings per
share versus an average of 16.8x; and at 4.6x latest book value versus an
average of 3.3x. On an enterprise value basis (market capitalization plus total
debt less cash and equivalents), Whitehall traded at 2.4x LTM Revenues versus
an average of 2.2x.


                                       16
<PAGE>

     Based upon the AVS closing stock price of $43.63 as of March 20, 1998 and
an Exchange Ratio of 0.5143x, the offer value for equity of $22.44 per share
was at the market price for Whitehall stock on March 20, 1998.


     SBCWDR analyzed and compared certain equity market multiples relating to
AVS to corresponding equity market multiples for the Selected Companies. SBCWDR
calculated various financial multiples for AVS and each of the Selected
Companies based on the most recent publicly available information. This
analysis showed that based on closing stock prices as of March 20, 1998, the
AVS Common Stock traded above the average of the Selected Companies. On an
equity value basis, AVS traded at 24.8x AVS management's estimated fiscal 1997
earnings per share versus an average of 22.5x; at 21.0x AVS management's
estimated fiscal 1998 earnings per share versus an average of 16.8x; and at
4.6x latest stockholders' equity versus an average of 3.3x. On an enterprise
value basis, AVS traded at 2.3x LTM revenues versus an average of 2.2x and at
16.1x LTM EBITDA versus an average of 13.1x.


     GENERALLY COMPARABLE COMPANY ACQUISITIONS ANALYSIS. SBCWDR analyzed seven
other acquisition transactions in the aviation services sector over the past
five years including AlliedSignal Inc.'s acquisition of the Banner Aerospace
hardware group, General Electric Co.'s acquisition of Greenwich Air Services,
Inc., Greenwich Air Services, Inc.'s acquisition of UNC Incorporated, Kellstrom
Industries, Inc.'s acquisition of International Aircraft Support, L.P., UNC
Incorporated's acquisition of Garrett Aviation Services, Inc., Greenwich Air
Services, Inc.'s acquisition of Aviall, Inc., UNC Incorporated's acquisition of
Johnson Technology Division of the Freedom Forge Corporation (the "Selected
Transactions"). Such analysis, based on publicly available information for the
twelve months preceding the announcement of the transaction, indicated that for
the Selected Transactions the median of the offer for assets was 0.7x LTM
revenues versus a Whitehall multiple of 2.4x.


     PREMIUM ANALYSIS. SBCWDR analyzed the premium paid per share of Whitehall
Common Stock over selected periods and compared it to the average historical
transaction premium of selected similarly sized transactions over the same time
periods. Based upon an offer for equity of $22.44 per share on March 20, 1998,
the premium to one day prior was 0.0%, to one week prior was -1.4%, and to one
month prior was 3.5%, compared to 21.2%, 26.5%, and 37.0% respectively for the
average of historical transactions. An offer for equity of $22.44 per share on
March 20, 1998 represents a 10.0% discount to AVS's 52 week high stock price
and a 42.5% premium to Whitehall's 52 week low stock price.


     DISCOUNTED CASH FLOW ANALYSIS. SBCWDR performed discounted cash flow
analyses to determine Whitehall's present value per share of Whitehall Common
Stock utilizing AVS management's projections from 1998 through 2003. This
analysis was not expected to determine the net present value of Whitehall as an
ongoing entity. For purposes of the analysis, SBCWDR utilized discount rates
ranging from 10.5% to 12.5% and terminal value EBITDA multiples ranging from
7.0x to 9.0x. The analysis indicated a range of values for the Whitehall Common
Stock from $22.63 to $30.64.


     SBCWDR is an internationally recognized investment banking firm which, as
a part of its investment banking business, regularly is engaged in the
evaluation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate, and other purposes. In the ordinary course of
its business, SBCWDR and its affiliates may actively trade or hold AVS Common
Stock for its own account and for the accounts of customers and may actively
trade or hold. AVS Common Stock for its own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.


     Pursuant to an engagement letter, dated March 18, 1998, between AVS and
SBCWDR, upon delivery of the fairness opinion AVS agreed to pay SBCWDR a fee
for services rendered in connection with the preparation of its fairness
opinion. AVS has also agreed to reimburse SBCWDR for the expenses reasonably
incurred by it in connection with its engagement (including reasonable counsel


                                       17

fees) and to indemnify SBCWDR and its officers, directors, employees, agents,
and controlling persons against certain expenses, losses, claims, damages or
liabilities in connection with its services, including those arising under the
federal securities laws.


THE MERGER AGREEMENT


     The following is a brief summary of all of the material provisions of the
Merger Agreement, a copy of which is attached as Annex A to this proxy
statement and is incorporated herein by reference. The description of the
Merger Agreement contained in the proxy statement does not purport to be
complete and is qualified in its entirety by reference to the full text of the
Merger Agreement.


     EFFECTIVE TIME; EFFECT OF THE MERGER. If the Merger Agreement is approved
and adopted by the requisite vote of the stockholders of AVS, and all other
conditions to the obligations of the parties to consummate the Merger are
satisfied or waived, the Merger will become effective upon the filing of the
Certificate of Merger or other appropriate documents in accordance with the
DGCL or at such time as is stated in the Certificate of Merger. Such filing is
expected to take place on the date of the closing of the transactions
contemplated by the Merger Agreement. The Merger will have the effects set
forth in Section 259 of the DGCL. As of the Effective Time, Sub will be merged
with and into AVS, with Whitehall continuing as the Surviving Corporation. The
separate corporate existence of Sub will terminate upon consummation of the
Merger. The Merger Agreement provides that (i) the certificate of incorporation
and the bylaws of Sub, as in effect at the Effective Time, will be the
certificate of incorporation and the bylaws of the Surviving Corporation until
thereafter amended pursuant to applicable law and the certificate of
incorporation of the Surviving Corporation, and (ii) the directors and officers
of Sub at the Effective Time will be the directors and officers of the
Surviving Corporation, and all such directors and officers will hold office
until their respective successors are duly appointed or elected in accordance
with applicable law.


     CLOSING DATE. Consummation of the Merger and the other transactions
contemplated by the Merger Agreement (the "Closing") will take place on the
date that the last of the conditions set forth in the Merger Agreement are
satisfied; or such other date as agreed to by the parties. The date on which
the Closing takes place is referred to as the "Closing Date."


     CERTIFICATE OF MERGER. Upon the satisfaction or waiver of all of the
conditions to the Merger set forth in the Merger Agreement, and provided that
the Merger Agreement has not been terminated, AVS and Whitehall will cause the
Certificate of Merger to be prepared, executed, delivered and filed with the
Delaware Secretary of State, upon which the Merger will become effective.


     CONVERSION OF SHARES. Pursuant to the Merger Agreement, at the Effective
Time, each share of Whitehall Common Stock outstanding immediately prior to the
Effective Time (other than shares held by Whitehall in its treasury or owned by
Whitehall or any subsidiary of Whitehall immediately prior to the Effective
Time, all of which will be canceled) will be converted in the Merger into the
right to receive, and will be exchangeable for, 0.5143 of a share of AVS Common
Stock. If any holder of Whitehall Common Stock would be entitled to receive a
number of shares of AVS Common Stock that includes a fraction, then in lieu of
a fractional share, such holder will be entitled to receive cash in an amount
determined by multiplying such fraction by the Average Closing Price of a whole
share of AVS Common Stock. The "Average Closing Price" of a share of AVS Common
Stock means the average of the daily closing price of a share of AVS Common
Stock as quoted on the NYSE for the period of ten consecutive trading days
ending on and including the last full trading day immediately preceding the
Closing Date.


     At the Effective Time it is estimated that former holders of Whitehall
Common Stock will hold approximately     % of the aggregate number of shares of
AVS Common Stock. This ownership percentage is based upon the number of shares
of Whitehall Common Stock and AVS Common Stock outstanding on      , 1998.


     At the Effective Time each share of capital stock of Sub outstanding
immediately prior to the Effective Time shall be converted into one share of
the common stock of the Surviving Corporation.


                                       18

     If, subsequent to the date of the Merger Agreement but prior to the
Effective Time, the AVS Common Stock is recapitalized or reclassified or AVS
shall effect any stock split, reverse stock split, or stock dividend of AVS
Common Stock, then the Exchange Ratio and the Average Closing Price shall be
appropriately and equitably adjusted to the kind and amount of shares of stock
and other securities and property which the holders of such shares of AVS
Common Stock would have been entitled to receive had such shares been issued
and outstanding as of the record date for determining stockholders entitled to
participate in such corporate event.


     WHITEHALL OPTIONS. Under the Merger Agreement, all Whitehall Options
outstanding at the Effective Time shall remain outstanding following the
Effective Time and shall be assumed by AVS. Each Whitehall Option assumed by
AVS shall be exercisable upon the same terms and conditions as under the
applicable Whitehall Stock Option Plan and the applicable option agreement
issued thereunder, except that (x) the unexercised portion of each such
Whitehall Option shall be exercisable for that whole number of shares of AVS
Common Stock (rounded down to the nearest whole share) equal to number of
shares of Whitehall Common Stock subject to the unexercised portion of such
Whitehall Option multiplied by the Exchange Ratio; and (y) the option exercise
price per share of AVS Common Stock shall be an amount equal to the option
exercise price per share of Whitehall Common Stock subject to such Whitehall
Option in effect at the Effective Time divided by the Exchange Ratio (the
option price per share, as so determined, being rounded upward to the nearest
full cent). No payment shall be made for fractional interests.


     In accordance with Whitehall's 1992 Incentive Stock Option Plan, each
Whitehall Option granted under such Plan, whether or not then exercisable, will
automatically become fully vested and immediately exercisable upon consummation
of the Merger. Whitehall Options granted under the 1992 Non-Employee Director
Stock Option Plan will not become fully vested and immediately exercisable upon
consummation of the Merger and will vest in accordance with their original
terms.

and obtaining any required consents or authorizations from any governmental or

     Whitehall has agreed to allow designated officers, attorneys, accountants
and other advisors and representatives of AVS reasonable access to all

its investigation of the business of AVS and its subsidiaries.

plans are terminated, such employees who remain employees of the Surviving
Corporation, AVS or any of its subsidiaries will be entitled to participate in
AVS's employee benefit plans on the same basis as AVS's employees in similar
positions are eligible to participate in such plans.


     INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Merger Agreement provides
that, unless otherwise required by law, the certificate of incorporation and
the bylaws of the Surviving Corporation shall contain provisions with respect
to the elimination of liability of directors and the indemnification of
directors, officers, employees and agents that are no less favorable than those
set forth in the certificate of incorporation and bylaws of Whitehall, as in
effect on the date of the Merger Agreement. From and after the Effective Time,
AVS and the Surviving Corporation shall jointly and severally indemnify, defend
and hold harmless each person who is, or has been at any time, or who becomes
prior to the Effective Time, an officer, director, employee or agent of
Whitehall or any of its subsidiaries (each an "Indemnified Party") against all
losses, reasonable expenses (including reasonable attorneys' fees), claims,
damages, liabilities or amounts that are paid in settlement of, or otherwise in
connection with, any threatened claim, action, suit, proceeding or
investigation (each a "Claim"), based in whole or in part on, or arising in
whole or in part out of, the fact that the Indemnified Party is or was a
director, officer, employee or agent of Whitehall or any of its subsidiaries
and pertaining to any matter existing or arising out of actions or omissions at
or prior to the Effective Time including, without limitation, any Claim arising
out of the Merger Agreement or any transactions contemplated thereby, in each
case to the fullest extent permitted under Delaware law.

<PAGE>

except for filings in connection with the Merger and any other documents
required to be filed after the Effective Time and except where the failure to

adverse effect on the Surviving Corporation or is not reasonably likely to
prevent or materially impair the ability of the parties to consummate the
transactions contemplated by the Merger Agreement;


      (f) the AVS Common Stock to be issued to the Whitehall stockholders in

Whitehall and its subsidiaries, taken as a whole;


      (e) from March 26, 1998 through the Effective Time, there shall not have
occurred any event that has had a material adverse effect on the financial

Stock or solely as a result of changes in the aviation industry which generally
impact on all companies in Whitehall's business (other than specifically on
Whitehall);


      (f) Whitehall shall have received all necessary consents with respect to
any contract, lease, purchase order, sales order, license agreement, permit,

occurred any event that has had a material adverse effect on the financial
condition, business, operations or prospects of AVS and its subsidiaries, taken

solely as a result of changes in the aviation industry which generally impact
on all companies in AVS's business (other than specifically on AVS);


      (d) the Ladenburg Opinion shall not have been withdrawn; provided,
however, that such withdrawal shall only permit Whitehall not to fulfill its
obligation to effect the Merger if the withdrawal of such opinion is a result
of a material adverse change in the financial condition, business, operation or
prospects of Whitehall and its subsidiaries, taken as a whole;


      (e) Whitehall shall have received, prior to the earlier of the date
Whitehall proxy statement is first mailed to Whitehall's stockholders and the

Merger Shares, the opinion of Baker & Botts, counsel to Whitehall, dated the
Closing Date, to the effect that the Merger will be treated for federal income
tax purposes as a reorganization within the meaning of Section 368(a) of the

and taken such other action as Whitehall shall reasonably request.


     TERMINATION. The Merger Agreement provides that it may be terminated and
the Merger may be abandoned at any time on or before its effect time by:


      (a) mutual consent of AVS and Whitehall;


      (b) either the Whitehall Board or the AVS Board if there has been a
breach by the other party of any of its material covenants or agreements set
forth in the Merger Agreement which breach has not, or cannot be, cured within
30 days after written notice thereof;


                                       24
<PAGE>

      (c) either the Whitehall Board or the AVS Board if there has been a
breach by the other party of any representation or warranty contained in the
Merger Agreement which would have a material adverse effect on such party;


      (d) either the Whitehall Board or the AVS Board if the Merger has not
occurred by September 30, 1998 (except that a party shall not be entitled to so
terminate if such party's failure to fulfill any obligation under the Merger
Agreement has been the cause of, or resulted in, the failure of the Merger to
occur on or before such date);


      (e) either the Whitehall Board or the AVS Board if the required vote of
the stockholders of Whitehall or AVS shall not have been obtained provided,
however, that neither party shall have the right to terminate the Merger
Agreement if the other party has caused (directly or indirectly) or aided in
the failure to obtain such approval; provided however that Whitehall shall not
be deemed to have caused or aided in the failure to obtain such approval if the
Whitehall Board withdraws its recommendation to Whitehall's stockholders by
accepting or recommending a Superior Proposal (as defined below);


      (f) either the Whitehall Board or the AVS Board if a court of competent
jurisdiction or a governmental regulatory or administrative agency or
commission shall have issued a final and non-appealable order or ruling
permanently restraining, enjoining or otherwise prohibiting the Merger or
compelling AVS, Sub or the Surviving Corporation to dispose of or hold separate
all or a material portion of the respective businesses or assets of AVS or
Whitehall, or sell or license any material product of AVS or Whitehall; or


      (g) the AVS Board if the Whitehall Board recommends a Superior Proposal
to the stockholders of Whitehall.


     NO SOLICITATION; TERMINATION FEE. Under the terms of the Merger Agreement,
Whitehall is prohibited from directly or indirectly, initiating or soliciting
any inquiries, proposals or offers from, engaging in any negotiations or
discussions with or providing any confidential information to, or entering into
any agreement or understanding with any person relating to, or with the intent
to effect, any Alternative Proposal. "Alternative Proposal" is defined under
the Merger Agreement to mean any proposal or offer (including, without
limitation, any proposal or offer to Whitehall's stockholders) with respect to
a merger, acquisition, consolidation or similar transaction involving, or any
purchase of all or a significant portion of the assets or any equity securities
of, Whitehall or its subsidiaries. The Whitehall Board may, however, to the
extent required by their fiduciary duties under applicable law, provide
information to, or participate in discussions with, any party that makes an
unsolicited inquiry with respect to Whitehall if the Whitehall Board reasonably
believes that such party may make an Alternative Proposal on terms that are
superior from a financial point of view to the terms of the Merger for
Whitehall's stockholders. Whitehall has agreed to immediately give written
notice to AVS of Whitehall's receipt of any Alternative Proposal or inquiry
with respect to making an Alternative Proposal.


     The Merger Agreement generally provides that the Whitehall Board shall not
approve, recommend or enter into any agreement with respect to any Alternative
Proposal; provided however, that if the Whitehall Board, after consultation
with and based upon the advice of independent legal counsel, determines in good
faith that it is necessary to do so in order to comply with its fiduciary
duties to stockholders under applicable law, the Whitehall Board may approve or
recommend or cause Whitehall to enter into a Superior Proposal but in each case
only after providing prompt written notice to AVS of its determination to do
so. The Merger Agreement defines a "Superior Proposal" to mean an Alternative
Proposal on terms that the Whitehall Board determines in its good faith
judgment to be more favorable to Whitehall stockholders than the Merger.


     In the event the Merger Agreement is terminated by AVS as a result of
Whitehall's Board having recommended a Superior Proposal to Whitehall's
stockholders, and Whitehall enters into an agreement


                                       25
<PAGE>

or an understanding with respect to a Superior Proposal within one (1) year of
the date of such termination, then Whitehall shall immediately pay AVS a fee of
$7.5 million (the "Termination Fee"). Additionally, if the Merger Agreement is
terminated by Whitehall or AVS because of a breach by the other party of any
representations and warranty set forth in the Merger Agreement which has a
material adverse effect on the breaching party, or because of a material breach
of any covenant or agreement by the other party, the breaching party shall
reimburse the non-breaching party for all actual out-of-pocket costs and
expenses incurred in connection with the Merger Agreement and the consummation
and negotiation of the transactions contemplated by the Merger Agreement,
including legal, professional and service fees and expenses; provided however
that the aggregate reimbursement for all such costs and expenses shall not
exceed $500,000. All such amounts shall be paid by wire transfer of same day
funds on the date of termination of the Merger Agreement or on the date which
Whitehall enters into an agreement with respect to a Superior Proposal if
terminated for such reason. If the fees described above are not paid when due
and in order to obtain such payments either party obtains a final
non-appealable judgment against the other party, the breaching party shall pay
the non-breaching party its costs and expenses together with interest on the
amount of the fee at a rate equal to 12% per annum.


     EXPENSES. Each of AVS and Whitehall will pay its own expenses (including,
without limitation, financial, legal and tax advice) incurred in connection
with the Merger Agreement and the transactions contemplated thereby except that
(i) the parties shall share equally all expenses incurred in connection with
the printing and mailing of the Whitehall proxy statement to the Whitehall
stockholders and (ii) the costs of printing and mailing this proxy statement
and the HSR filing fees in connection with the Merger shall be borne by AVS.


     AMENDMENT AND WAIVER. AVS and Whitehall may amend the Merger Agreement, by
action taken by their respective boards of directors, either before or after
approval by their stockholders of the Merger Agreement, except that after any
such stockholder approval no amendment may be made which by law requires
further approval by such stockholders without obtaining such further approval.
At any time prior to the Effective Time, any party to the Merger Agreement, by
action of its board of directors, may, to the extent legally allowed, extend
the time for the performance of any of the obligations or other acts of the
other parties, waive any inaccuracies in the representations or warranties made

                                AVS'S BUSINESS


GENERAL


     AVS is a leading provider of fully integrated aviation inventory services
and a recognized worldwide leader in the redistribution of aircraft spare
parts. AVS sells aircraft spare parts and provides inventory and repair
services to major commercial passenger airlines, air cargo carriers,
maintenance and repair facilities and other redistributors throughout the
world. Parts sold by AVS include rotable and expendable airframe and engine
components for commercial airplanes, including Boeing, McDonnell Douglas,
Lockheed and Airbus aircraft and Pratt & Whitney, General Electric and Rolls
Royce jet engines. Inventory management services offered by AVS include
purchasing services, repair management, warehouse management, aircraft
disassembly services, and consignment and leasing of inventories of aircraft
parts and engines. AVS also manufactures certain aircraft parts for sale to
original equipment manufacturers ("OEMs"), including precision engine parts,
and provides certain aircraft parts repair services at its FAA-licensed repair
facilities.


     AVS believes that the annual worldwide market for aircraft spare parts is
approximately $10.0 billion, of which approximately $1.3 billion reflects
annual sales of aircraft spare parts in the redistribution market. The market
for spare parts and the redistribution market in particular are growing due to
(i) the increasing size and the age of the worldwide airline fleet (the
worldwide fleet of commercial airplanes is expected to double from 1996 to
2016), and (ii) increased outsourcing by airlines of inventory management
functions in response to cost control pressures. These pressures have also
contributed to a reduction in the number of approved vendors utilized by the
airlines and maintenance and repair facilities, which in turn has led to
consolidation in the redistribution market. The aircraft spare parts
redistribution market is highly fragmented, with a limited number of large,
well-capitalized companies selling a broad range of aircraft spare parts, and
numerous smaller competitors servicing specialized niches. AVS believes its
diverse product and service offerings, superior management information systems,
financial strength and access to capital markets allow it to capitalize on the
current industry environment.


     AVS's strategy is to increase revenues and operating income through
internal growth combined with new product and service offerings. Growth is
expected to be achieved through continued customer penetration in existing
markets, expansion into new product areas, continued investment in the size and
breadth of its inventory and by continuing to offer customers a broad array of
inventory management services. These services allow customers to reduce their
costs of operations by outsourcing some or all of their inventory management
functions and to take advantage of opportunities to maximize the value of their
spare parts inventory. AVS further intends to increase the types of aircraft
parts which it manufactures for its OEM customers and the repair services which
it offers to its customers. AVS will seek to develop new products and services
internally, as well as through acquisitions of other companies, assets or
product lines that would expand the products and services which AVS offers to
its customers. AVS believes that a diversified platform of services will better
allow it to serve the needs of its larger customers, and to benefit from the
continuing consolidation of vendors by the airlines.


     Since completion of its initial public offering in July 1996, AVS has
acquired six businesses which leverage AVS's product and service base beyond
the redistribution of aircraft spare parts into new parts distribution,
manufacturing and maintenance, and repair and overhaul. During 1996, AVS
acquired the aircraft bearings division of Dixie Bearings, Inc., a leading
provider of aircraft bearings, and related products to commercial airlines,
cargo carriers and overhaul service facilities, and AvEng Trading Partners,
Inc., a redistributor of aircraft engine parts. During 1997, AVS acquired
Aerocell Structures, Inc., an FAA-certified maintenance, overhaul and repair
facility, Kratz-Wilde Machine Company, a manufacturer of specialty machined
metal parts for jet engines, and Apex Manufacturing, Inc., a precision
manufacturer of specialty machined metal parts including shafts, fuel shrouds,
housings and couplings for aerospace actuating systems. In March 1998, AVS
acquired Caribe Aviation, Inc. and its subsidiary, Aircraft Interior Design,
Inc. Caribe is an FAA-licensed repair station specializing in the maintenance,
repair and overhaul of hydraulic, pneumatic, electrical and electromagnetic
aircraft


                                       28

components and Aircraft manufactures plastic cabin interior replacement parts
under FAA-PMA approval and refurbishes aircraft interior components. See "AVS's
Management Discussion--Overview" and"--Results of Operations."


INDUSTRY OVERVIEW


     GROWTH IN MARKET FOR AIRCRAFT SPARE PARTS. According to Boeing's 1997
Current Market Outlook (the "Boeing Report"), the worldwide fleet of commercial
airplanes is expected to double from approximately 11,500 airplanes at the end
of 1996 to approximately 23,000 airplanes by 2016. Further, the Boeing Report
projects that cargo jet aircraft will increase from approximately 1,230
airplanes in 1996 to approximately 2,350 airplanes by 2016. The majority of the
airplanes delivered to cargo operators are expected to be used aircraft
converted from commercial passenger service. Additionally, AVS believes that
the number of planes in service for more than 10 years is continuing to
increase, and these older planes are the primary market for redistributors.
Finally, cost considerations are causing many airlines and repair and
maintenance facilities which had historically purchased their parts inventory
requirements from new parts manufacturers to utilize aircraft spare parts sold
by redistributors. AVS believes that all of these factors will increase the
demand for aircraft spare parts from the redistribution market.


     Since AVS's customers consist of airlines, maintenance and repair
facilities that service airlines and other aircraft spare parts redistributors,
as well as original equipment manufacturers, AVS's business is impacted by the
economic factors which affect the airline industry. When such factors adversely
affect the airline industry, they tend to reduce the overall demand for
aircraft spare parts, causing downward pressure on pricing and increasing the
credit risk associated with doing business with airlines. Additionally, factors
such as the price of fuel affect the aircraft spare parts market, since older
aircraft (into which aircraft spare parts are most often placed) become less
viable as the price of fuel increases. There can be no assurance that economic
and other factors which may affect the airline industry will not have an
adverse impact on AVS's business, financial condition or results of operations.
 


     INCREASED OUTSOURCING OF INVENTORY MANAGEMENT FUNCTIONS. Airlines incur
substantial expenditures in connection with fuel, labor and aircraft ownership.
Further, airlines have come under increasing pressure during the last decade to
reduce the costs associated with providing air transportation services. While
several of the expenditures required to operate an airline are beyond the
direct control of airline operators (e.g., the price of fuel and labor costs),
AVS believes that obtaining replacement parts from the redistribution market
and outsourcing inventory management functions are areas in which airlines can
reduce their operating costs. Outsourcing inventory management functions allows
these functions to be handled less expensively and more efficiently by a
redistributor like AVS that can achieve economies of scale unavailable to
individual airlines. Several small and start-up airlines and cargo operators do
not presently own an inventory of aircraft spare parts, but rather have entered
into agreements with redistributors for the supply of all or a portion of their
aircraft spare parts requirements. Other airlines, including several large
airlines, have begun to outsource portions of their purchasing services, repair
management and warehouse management.


     CONSOLIDATION IN THE AIRCRAFT PARTS MARKET. In order to reduce purchasing
costs and streamline purchasing decisions, airline purchasing departments have
been reducing the number of their approved suppliers. During the last few
years, several major airlines have reduced their supplier lists from as many as
50 to a core group of five to ten suppliers. As a result of reductions in the
supplier base by airline purchasing departments, there has been and AVS
believes there will continue to be a consolidation in the redistribution
market. Furthermore, over the last few years, several smaller and start-up
airlines have chosen to lease inventories of aircraft spare parts in order to
preserve capital while maintaining adequate spare parts support.


     CONSIGNMENT AND BULK PURCHASES. Certain of AVS's customers adjust
inventory levels on a periodic basis by disposing of excess aircraft parts.
Traditionally, larger airlines have used internal purchasing agents to manage
such dispositions. AVS believes that major airlines and other owners of


                                       29
<PAGE>

aircraft spare parts, in order to concentrate on their core businesses and to
more effectively redistribute their excess parts inventories, are increasingly
entering into long-term consignment agreements with redistributors. By
consigning inventories to a redistributor such as AVS, customers are able to
distribute their aircraft spare parts to a larger number of prospective
inventory buyers, allowing the customer to maximize the value of its inventory.
Consignment also enables AVS to offer for sale a significant parts inventory at
minimal capital cost to AVS. Consignment agreements are generally entered into
on a long-term basis for a large group of parts or entire airplanes which are
disassembled for sale of the individual parts. In the Boeing Report it is noted
that approximately 4,070 aircraft will be removed from active commercial
service between 1997 and 2016. Many of these aircraft will be disassembled in
order to sell their parts.


COMPETITIVE STRENGTHS


     AVS believes that its competitive position in the markets which it serves
is based on its diverse product offerings, sophisticated inventory management
information systems and a consistent record of meeting rigorous customer
requirements.


     DIVERSIFIED PLATFORM OF PRODUCTS AND SERVICES. AVS believes that the
breadth of inventory management services which it provides to its customers,
including a wide range of repair and overhaul services and specialized
manufacturing, allows AVS to be a vendor of choice to its customers in a highly
fragmented industry. AVS has over 1,000 customers, including commercial
passenger airlines, air cargo carriers and maintenance and repair facilities.


     LARGE INVENTORY BASE.AVS believes that it has one of the largest
inventories of aircraft spare parts in the world, with over 552,000 line items
currently in stock. AVS's inventory supports the worldwide commercial fleet of
over 11,500 aircraft including Airbus A300, A31x, A32x and A340 series
aircraft, Boeing 707, 727, 737, 747, 757, 767 and 777 series aircraft,
McDonnell Douglas DC-8, DC-9, DC-10, MD-8x and MD-11 series aircraft, and the
Lockheed L-1011 aircraft. In addition, AVS has parts available for the
following engine types: General Electric CF6, SNECMA CFM-56, Pratt and Whitney
JT-3, JT-8, JT-9 and PW-2000 and the Rolls Royce RB-211.


     PROPRIETARY MANAGEMENT INFORMATION SYSTEMS. AVS's proprietary management
information systems comprise an integral component of AVS's position as a
leader in its industry. As industry, regulatory and public awareness have
focused on safety, documentation and traceability of aircraft parts have become
key factors in competitiveness. AVS's MIS systems collect and report data
regarding inventory turnover, documentation, pricing, market availability and
customer demographic information on more than 3.7 million line items. Access to
such information enables AVS to be aware of and to capitalize on the changing
trends in the marketplace. AVS utilizes electronic data scanning and document
image storage technology for rapid and accurate retrieval of inventory
traceability documents. AVS is continuing to invest in technology in order to
allow AVS to maintain its strength in this area. In that regard, AVS is
currently in the early stages of purchasing and implementing a new management
information system that management believes will allow AVS to mitigate the Year
2000 issues currently inherent in AVS's existing system. See "AVS's
Management's Discussion--Liquidity and Capital Resources."


     WORLDWIDE MARKETING PRESENCE. AVS conducts business in more than 100
countries and utilizes sales representatives in 23 countries. This
international presence allows AVS to meet the demands of its global customer
base and provides for a timely supply of parts and services. During the years
ended December 31, 1996 and 1997, 41.6% and 28.9%, respectively, of AVS's
revenues were derived from sales to international customers and 58.4% and
71.1%, respectively, were derived from sales to domestic customers.


     SIGNIFICANT FINANCIAL AND OTHER RESOURCES. As a result of AVS's strong
capital position, AVS is able to take advantage of opportunities which arise in
the market from time to time to expand its products and services, make selected
acquisitions and evaluate bulk purchases of inventory. AVS's


                                       30
<PAGE>

market presence, industry experience, sophisticated MIS systems and capital
strength enable AVS to quickly analyze and complete purchases, giving AVS a
competitive advantage in the market.


AIRCRAFT SPARE PARTS


     Aircraft spare parts can be categorized by their ongoing ability to be
repaired and returned to service. The general categories are as follows: (a)
rotable; (b) repairable; and (c) expendable. A rotable is a part which is
removed periodically as dictated by an operator's maintenance procedures or on
an as needed basis and is typically repaired or overhauled and re-used an
indefinite number of times. An important subset of rotables is life limited
parts. A life limited rotable has a designated number of allowable flight hours
and/or cycles (one take-off and landing generally constitutes one cycle) after
which it is rendered unusable. A repairable is similar to a rotable except that
it can only be repaired a limited number of times before it must be discarded.
An expendable is generally a part which is used and not thereafter repaired for
further use. AVS's inventory consists in large part of rotable and repairable
parts which are regularly required by its customers. AVS also maintains an
inventory of expendable parts.


     Aircraft spare parts conditions are classified within the industry as (a)
factory new, (b) new surplus, (c) overhauled, (d) serviceable and (e) as
removed. A factory new or new surplus part is one that has never been installed
or used. Factory new parts are purchased from manufacturers or their authorized
distributors. New surplus parts are purchased from excess stock of airlines,
repair facilities or other redistributors. An overhauled part has been
completely disassembled, inspected, repaired, reassembled and tested by a
licensed repair facility. An aircraft spare part is classified serviceable if
it is repaired by a licensed repair facility rather than completely
disassembled as in an overhaul. A part may also be classified serviceable if it
is removed by the operator from an aircraft or engine while operating under an
approved maintenance program and is functional and meets any manufacturer or
time and cycle restrictions applicable to the part. A factory new, new surplus,
overhauled or part designation indicates that the part is eligible for
immediate use on an aircraft. A part in an as removed condition requires
functional testing, repair or overhaul by a licensed facility prior to being
returned to service in an aircraft.


     AVS's inventory consists principally of new, overhauled, serviceable and
repairable aircraft parts that are purchased from many sources. Before parts
may be installed in an aircraft, they must meet certain standards of condition
established by the FAA and/or the equivalent regulatory agencies in other
countries. Specific regulations vary from country to country, although
regulatory requirements in other countries generally coincide with FAA
requirements. Parts must also be traceable to sources deemed acceptable by such
agencies. Parts owned or acquired by AVS may not meet applicable standards or
standards may change in the future, causing parts which are already contained
in AVS's inventory to be scrapped or modified. Aircraft manufacturers may also
develop new parts to be used in lieu of parts already contained in AVS's
inventory. In all such cases, to the extent that AVS has such parts in its
inventory, their value may be reduced.


OPERATIONS


     AVS's core business is the buying and selling of aircraft spare parts. AVS
also provides value-added inventory management services to its customers,
manufactures aircraft parts for its OEM customers and repairs aircraft parts at
its FAA-licensed repair facilities. AVS believes that providing its customers
with a diversified platform of services will allow AVS to significantly expand
its business in the future.


  INVENTORY SALES


     The daily operations of AVS encompass inventory sales, brokering and
exchanging aircraft spare parts. AVS advertises its available inventories held
for sale or exchange on the Inventory Locator Service ("ILS") and the Airline
Inventory Redistribution System ("AIRS") electronic databases. Buyers of
aircraft spare parts can access the ILS and AIRS databases and determine the
companies


                                       31
<PAGE>

which have the desired inventory available. AVS estimates that 70% of its daily
sales activity results from an ILS or AIRS inquiry. All major airlines and
repair agencies subscribe to one or both of these databases and, accordingly,
AVS maintains continual on-line direct access with them. AVS also maintains
direct Electronic Data Interchanges ("EDI") with significant customers. These
programs provide for the electronic exchange of pricing and availability from
AVS to the customer in response to an electronic request for quotation. ILS and
AIRS do not, however, list price information relating to particular parts.
Knowledge of the value of particular parts is provided by AVS's proprietary
database.


     AVS currently has over 552,000 line items in stock with market
availability, pricing and historical data available on more than 3.7 million
line items. AVS sells new, overhauled and serviceable replacement parts from
its inventory. Additionally, AVS will purchase parts on behalf of its customers
against specific orders. AVS also offers a customer exchange program for
rotables. In an exchange transaction, AVS exchanges a new surplus, overhauled
or serviceable component taken from stock with a customer's as-removed unit
which has failed. AVS receives an exchange fee for completing the transaction,
plus reimbursement from the customer for the cost to overhaul or repair the
as-removed unit. If the as-removed part cannot be repaired, it is returned to
the customer and the exchange transaction is converted to an outright sale at a
sales price agreed upon at the time the exchange transaction was negotiated.


     AVS's inventory consists principally of new, overhauled, serviceable and
repairable aircraft spare parts that are purchased from many sources. Parts
that are to be installed in an aircraft must meet certain standards established
by the FAA and/or the equivalent regulatory agencies in other countries.
Specific regulations vary from country to country, although regulatory
requirements in other countries generally coincide with FAA requirements. Parts
must be traceable to sources deemed acceptable by such agencies. See
"Government Regulation and Traceability" below. Parts owned or acquired by AVS
may not meet applicable standards or standards may change in the future,
causing parts which are already contained in AVS's inventory to be scrapped or
modified. Aircraft manufacturers may also develop new parts to be used in lieu
of parts already contained in AVS's inventory. In all such cases, to the extent
that AVS has such parts in its inventory, their value may be reduced.


  INVENTORY MANAGEMENT SERVICES


     AVS is meeting the outsourcing requirements of its customers through
providing a number of inventory management services. These services assist
airlines in streamlining their inventory management operations while utilizing
their capital more efficiently and reducing their costs. Through the offering
of various services, AVS believes it can provide an inventory management
program geared to a customer's particular requirements.


     CONSIGNMENT. By consigning inventories to a redistributor such as AVS,
customers are able to distribute their aircraft spare parts to a larger number
of prospective inventory buyers, allowing the customer to maximize the value of
its inventory. Consignment also enables AVS to offer for sale significant parts
inventory at minimal capital cost to AVS. AVS presently has several consignment
agreements in place with major airlines, and its revenues from consignment
arrangements have increased significantly over the last few years.


     PURCHASING SERVICES AND REPAIR MANAGEMENT. AVS provides services whereby
it purchases spare parts for several smaller and start-up airlines. These
arrangements allow AVS's customers to take advantage of AVS's greater
purchasing power. AVS also provides repair management services to certain of
its customers, whereby AVS receives a fee for managing a customer's spare parts
repair requirements. AVS believes that it is well positioned to offer these
repair management services, since a significant portion of the component repair
cost relates to the procurement of the parts to be utilized in the repair.
Additionally, because of its size, AVS procures significant repair services for
its own account, and maintains comprehensive databases on repair and
replacement part costs, allowing it to capitalize on favorable pricing for
repair services available only to large users of repair services. This permits
AVS to offer these services on a cost-effective basis to its customers.


                                       32
<PAGE>

     LEASING. AVS (through its subsidiary, Aviation Sales Leasing Company)
provides long-term leasing of inventories of aircraft spare parts to airline
customers. An increasing number of smaller and start-up airlines have chosen to
lease aircraft spare parts in order to preserve capital while maintaining
adequate spare parts support. AVS believes that it has a competitive advantage
in aircraft engines and aircraft spare parts leasing due to its ability to
maximize the residual value of the parts after termination of the lease through
sales of the parts in the ordinary course of its business. As of December 31,
1996 and 1997 and March 31, 1998, AVS had $18.0 million, $22.8 million and
$16.8 million, respectively, of inventories on long-term lease.


     AIRCRAFT DISASSEMBLY. AVS provides "teardown" services at its Ardmore,
Oklahoma facility, both in connection with consignment arrangements and for the
purpose of returning disassembled aircraft spare parts directly to a customer.
AVS expects that the increasing number of older aircraft will increase the
demand for aircraft spare parts and result in expanded opportunities for
aircraft disassembly.


     WAREHOUSE MANAGEMENT. AVS provides warehouse management services which
allow a customer to avoid the costs associated with the operation of its own
inventory warehouse facility by maintaining inventory at AVS's warehouse
facility. AVS also will manage a customer's inventory at the customer's own
facility.


  MANUFACTURING AND REPAIR SERVICES


     The Boeing Report projects that global air travel will increase by close
to 75% in the aggregate by the year 2006. In addition, average passenger fleet
miles flown are also expected to increase significantly over the next few
years, requiring current operators to increase the size of their fleets.
Further, many new airlines are expected to commence operations in the United
States and abroad. These increases in passenger travel and the number of
aircraft in service increases the demand for manufacture and repair services.
Consequently AVS foresees the manufacture and repair of aircraft parts as a
profit center with significant growth opportunity, and as an integral component
of AVS's expansion strategy.


     During the last half of 1997 and the first quarter of 1998, AVS completed
four acquisitions furthering its objective of expanding the services which it
offers to its customers to include manufacturing of aircraft parts for sale to
OEMs and repair services. Descriptions of the companies acquired are as
follows:


      Aerocell specializes in the maintenance, repair and overhaul of airframe
      components, including bonded and structural assemblies for commercial
      aircraft. Aerocell is an FAA-licensed repair facility with limited
      airframe ratings for flight controls, doors, fairing panels, nacelle
      systems and exhaust systems.


      Kratz specializes in the manufacture of machined components primarily for
      jet engines, and also produces automotive and faucet components. Kratz is
      a leading supplier of CFM56 and CF6 engine components to General
      Electric's Aircraft Engine business, with three manufacturing facilities
      in the greater Cincinnati area. The acquisition of Kratz provides AVS
      with precision manufacturing capabilities which AVS believes will allow
      it to expand its relationship with its current and future OEM customers.


      Apex, located in Phoenix, Arizona, manufactures precision aerospace parts
      and specializes in the machining of metal parts, including precision
      shafts, fuel shrouds, housings and couplings for aerospace actuating
      systems, fuel controls and engines.


      Caribe, located in Miami, Florida, is an FAA-licensed repair station
      specializing in the maintenance, repair and overhaul of hydraulic,
      pneumatic, electrical and electromagnetic aircraft components, as well as
      avionics and instruments on Airbus and Boeing aircraft. Caribe's
      wholly-owned subsidiary, Aircraft, manufactures plastic cabin interior
      replacement parts under FAA-PMA approval and refurbishes aircraft
      interior components, including passenger and crew seats.


                                       33

SALES AND MARKETING; CUSTOMERS


     AVS utilizes inside salespersons, regional field salespersons, independent
contract representatives and overseas sales offices in its sales and marketing
efforts. AVS's outside sales force is responsible for obtaining new customers
and maintaining relationships with existing customers. The majority of AVS's
day-to-day sales are accomplished through AVS's inside sales force.


     AVS staffs its South Florida facility to provide sales and delivery
services seven days a week, 24 hours a day. This service is critical to provide
support to airline customers which, at any time, may have an aircraft grounded
in need of a particular part. AVS's South Florida location, with easy access to
Miami International Airport and Fort Lauderdale International Airport, assists
AVS in providing reliable and timely delivery of purchased products.


     AVS has over 1,000 customers, which include commercial passenger airlines,
air cargo carriers, maintenance and repair facilities and other aircraft parts
redistribution companies. AVS's top ten customers accounted for approximately
23%, 26% and 29% of operating revenues, respectively, for the three years ended
December 31, 1995, 1996 and 1997. No single customer accounted for more than
10% of operating revenues for the year ended December 31, 1997.


MANAGEMENT INFORMATION SYSTEMS


     AVS has developed a proprietary management information system which is an
important component of its business and a significant factor in AVS's leading
position in the redistribution market. AVS's management information system
collects and reports data regarding inventory turnover and traceability,
pricing, market availability, customer demographics and other important data
used by AVS. AVS currently maintains marketing data on and is able to estimate
the value of more than 3.7 million line items. AVS also maintains databases on
recommended upgrades or replacements, including airworthiness directives.
Access to such information gives AVS the best possible opportunity to avoid
purchases of aircraft spare parts which might be deemed unusable. In addition,
the data maintained by AVS allows it to provide its customers with information
with respect to obsolescence and interchangeability of parts. AVS utilizes
electronic data scanning and document image storage technology for accurate and
rapid retrieval of inventory traceability documents that must accompany all
sales. These documents are required by AVS's customers in order for them to
comply with applicable regulatory guidelines. AVS believes that its continued
investment in the development of information systems is a key factor in
maintaining its competitive advantage.


     AVS believes that to maintain its competitive advantages, accommodate
growth and keep pace with the rapid changes in technology, it will be prudent
to continue to acquire state of the art management information systems to
ensure the capability to meet AVS's needs for the foreseeable future. In that
regard, AVS is currently in the early stages of purchasing and implementing a
new management information system that management believes will allow AVS to
mitigate the Year 2000 issues currently inherent in AVS's existing system. See
"AVS's Management's Discussion--Liquidity and Capital Resources."


COMPETITION


     There are numerous suppliers of aircraft parts in the aviation market
worldwide and, through inventory listing services, customers have access to a
broad array of suppliers. These include major aircraft manufacturers, airline
and aircraft service companies and aircraft spare parts redistributors.
Competition in the redistribution market is generally based on price,
availability of product and quality, including traceability. AVS's major
competitors include AAR Corp., The Ages Group and The Memphis Group. There is
also substantial competition, both domestically and overseas, from smaller,
independent dealers who generally participate in niche markets. Several of
AVS's competitors have greater financial and other resources than AVS. There
can be no assurance that competitive pressures will not materially and
adversely affect AVS's business, financial condition or results of operations.

GOVERNMENT REGULATION AND TRACEABILITY


     The aviation industry is highly regulated. While AVS's spare parts
business is not regulated, the aircraft spare parts which it sells to its
customers must be accompanied by documentation which enables the customer to
comply with applicable regulatory requirements. Additionally, AVS must be
certified by the FAA and, in some cases, by OEMs in order to manufacture or
repair aircraft components. Although AVS believes that its newly acquired
manufacturing and repair operations are in material compliance with applicable
regulations, there can be no assurance of this fact. Further, there can be no
assurance that new and more stringent government regulations will not be
adopted in the future or that any such new regulations, if enacted, would not
have a material adverse effect on AVS's business, financial condition or
results of operations.


     The FAA regulates the manufacture, repair and operation of all aircraft
and aircraft parts operated in the United States. Its regulations are designed
to ensure that all aircraft and aircraft equipment are continuously maintained
in proper condition to ensure safe operation of the aircraft. Similar rules
apply in other countries. All aircraft must be maintained under a continuous
condition monitoring program and must periodically undergo thorough inspection
and maintenance. The inspection, maintenance and repair procedures for the
various types of aircraft and aircraft equipment are prescribed by regulatory
authorities and can be performed only by certified repair facilities utilizing
certified technicians. Certification and conformance is required prior to
installation of a part on an aircraft. Presently, AVS utilizes FAA and/or Joint
Aviation Authority certified repair stations (including AVS's FAA-licensed
repair facilities) to repair and certify parts to ensure worldwide
marketability. The operations of AVS may in the future be subject to new and
more stringent regulatory requirements. In that regard, AVS closely monitors
the FAA and industry trade groups in an attempt to understand how possible
future regulations might impact AVS.


     An important factor in the aircraft spare parts redistribution market
relates to the documentation or traceability that is supplied with an aircraft
spare part. AVS requires all of its suppliers to provide adequate documentation
as dictated by the appropriate regulatory authority. AVS utilizes electronic
data scanning and storage techniques to maintain complete copies of all
documentation. Documentation required includes, where applicable, (a) a
maintenance release from a certified airline or repair facility signed and
dated by a licensed airframe and/or power plant mechanic who repaired the
aircraft spare part and an inspector certifying that the proper methods,
materials and workmanship were used, (b) a "teardown" report detailing the
discrepancies and corrective actions taken during the last shop repair, and (c)
an invoice or purchase order from an approved source.


PRODUCT LIABILITY


     AVS's business exposes it to possible claims for personal injury or death
which may result from the failure of an aircraft spare part sold, manufactured
or repaired by it. While AVS maintains what it believes to be adequate
liability insurance to protect it from such claims, and while no material
claims have, to date, been made against AVS, no assurance can be given that
claims will not arise in the future or that such insurance coverage will be
adequate. Additionally, there can be no assurance that insurance coverages can
be maintained in the future at an acceptable cost. Any such liability not
covered by insurance could have a material adverse effect on the financial
condition of AVS.


     AVS will have exposure to product liability claims in the event that the
use of its leased aircraft, aircraft engines or aircraft spare parts inventory
is alleged to have resulted in bodily injury or property damage.


EMPLOYEES


     As of December 31, 1997, AVS employed approximately 850 persons. None of
AVS's employees are covered by collective bargaining agreements. AVS believes
that its relations with its employees are good.

PROPERTIES


     AVS's executive offices are located in Miami, Florida. All of AVS's
properties are maintained on a regular basis and are adequate for AVS's present
requirements. AVS is actively considering the possibility of consolidating its
inventory into a single warehouse facility.


     The following table identifies, as of April 29, 1998, the principal
properties utilized by AVS. See Notes 6 and 8 to Notes to AVS's Consolidated

LEGAL PROCEEDINGS


     AVS is not presently involved in any material legal proceedings. From time
to time AVS may be named as a defendant in suits for product defects, breach of
warranty, breach of implied warranty of merchantability or other actions
relating to products which it distributes which are manufactured by others. AVS
believes that this exposure is adequately covered by its products liability
insurance.

(1) Caribe, which was acquired on March 6, 1998, Dixie, which was acquired on
    August 9, 1996 and Kratz, which was acquired on October 17, 1997, were
    accounted for under the purchase method of accounting and accordingly,
    Caribe's, Dixie's and Kratz's results of operations have been included in
    AVS's historical results of operations from the dates of their
    acquisition. AvEng, which was acquired on December 10, 1996, Aerocell,
    which was acquired on September 30, 1997, and Apex, which was acquired on
    December 31, 1997, were accounted for under the pooling of interest method
    of accounting. As such AvEng is included in AVS's historical financial
    results for all periods presented subsequent to 1995, and Aerocell and
    Apex are included for all periods presented subsequent to 1996. Historical
    operating results and financial position for periods presented prior to
    1996 have not been restated to give retroactive effect to the acquisition
    of AvEng and historical operating results and financial positions for
    periods presented prior to 1997 have not been restated to give retroactive
    effect to the acquisition of Aerocell and Apex, due to the immateriality
    of the restated amounts.
(2) Periods presented prior to 1997 include pro forma adjustments to record
    income taxes, as AVS conducted its business as a partnership prior to June
    26, 1996.
(3) Weighted average common and common equivalent shares used in calculating
    diluted earnings per share are 5,859,542 for 1993; 5,923,103 for 1994;
    6,259,542 for 1995; 7,819,837 for 1996; 9,484,097 for 1997; 9,463,967 for
    the three months ended March 31, 1997 and 9,592,820 for the three months
    ended March 31, 1998.
(4) The 1995 and 1996 AVS per share data assumes that the 4,425,000 common
    shares issued to the partners and the 575,000 shares of common stock, the
    net proceeds in respect of which were paid to J/T Aviation Partners, were
    outstanding for periods prior to the closing of AVS's initial public
    offering in July 1996.

OVERVIEW


     AVS's predecessor, Aerospace International Services ("AIS"), commenced
operations in February 1992 through the acquisition of certain aircraft spare
parts owned by Eastern Air Lines, Inc. (the "Eastern Inventory"), for an
aggregate purchase price of $55.2 million. During the period between February
1992 and December 1994, the primary business of AIS was the marketing and sale
of the Eastern Inventory. During December 1994, AIS organized ASC Acquisition
Partners L.P. (the "Partnership"), and completed the acquisition of certain
assets and assumed certain liabilities of the Aviation Sales Company business
unit ("ASC") from Aviall Services, Inc. for an aggregate purchase price of
$46.8 million.


     On July 2, 1996, AVS closed its initial public offering ("IPO") of
3,250,000 shares of its common stock at an offering price of $19 per share. On
July 25, 1996, AVS sold an additional 487,500 shares of its common stock at the
same price upon the exercise of an underwriters' over-allotment option.


     Immediately prior to the IPO, all but one of the parties holding interests
in the Partnership contributed their interest in the Partnership to AVS in
exchange for shares of common stock. Simultaneously, one of the parties holding
an interest in the Partnership contributed its interest in the Partnership to
AVS in exchange for shares of common stock and an amount equal to the proceeds
to be received by AVS from the underwriters for 575,000 shares of common stock
sold in the offering.


     AVS received aggregate net proceeds in the IPO of $64.6 million. Of this
amount, $10.2 million was used to repay the indebtedness incurred to one of the
stockholders of AVS in connection with the formation of AVS and the balance was
used to repay senior and subordinated indebtedness. As a result of the
repayment of indebtedness with the proceeds of the IPO, AVS wrote-off
approximately $3.1 million in deferred financing costs relating to that debt.


     Subsequent to the completion of the IPO, on August 9, 1996, AVS completed
the acquisition of certain assets of the business of Dixie relating primarily
to the sale of new bearings for use in aircraft for the purchase price of
approximately $9.0 million. The acquisition was accounted for using the
purchase method of accounting. As a result of the Dixie acquisition, AVS's
operating revenues increased approximately $7.0 million from the date of the
acquisition through December 31, 1996.


     On December 10, 1996 (effective November 30, 1996), AVS completed the
acquisition of AvEng for a purchase price of approximately $8.0 million,
payable by the issuance of an aggregate of 400,000 shares of AVS's common
stock. The acquisition was accounted for using the pooling of interests method
of accounting. As a result of the acquisition, AVS's operating revenues include
AvEng's total revenues for 1996, amounting to approximately $9.3 million.


     During 1997, AVS completed three acquisitions. The first acquisition,
which was completed in September 1997, was a merger accounted for as a pooling
of interests with Aerocell. Aerocell operates an FAA-licensed overhaul and
repair facility. The purchase price paid for Aerocell was approximately $18.8
million, payable by issuance of an aggregate of 620,970 shares of AVS's common
stock. As a result of the acquisition of Aerocell, AVS's operating revenues for
the year ended December 31, 1997 increased by approximately $19.3 million. The
second acquisition, which was completed in October 1997, was of the assets of
Kratz, a company which specializes in the manufacture of machined components
primarily for jet engines (and also produces certain automotive and faucet
components). AVS paid approximately $39.6 million, including acquisition costs
and net of cash acquired, to acquire the assets of Kratz and accounted for the
acquisition under the purchase method of accounting. As a result of the
acquisition of Kratz, AVS's operating revenues increased by approximately $6.5
million from the date of acquisition through December 31, 1997. The third
acquisition, which was completed in December 1997 and was accounted for in a
transaction accounted for as a pooling of interests, was the acquisition of
Apex, a precision aerospace manufacturer specializing in the machining of metal
parts,


                                       39
<PAGE>

including precision shafts, fuel shrouds, housings and couplings for aerospace
actuating systems, fuel controls and engines. The purchase price paid to
acquire Apex was $8.4 million, payable by the issuance of an aggregate of
238,572 shares of AVS's common stock. As a result of the acquisition of Apex,
AVS's operating results for the year ended December 31, 1997 increased by
approximately $7.3 million.


     To date during 1998, AVS has completed one acquisition. On March 6, 1998,
AVS acquired Caribe and its wholly-owned subsidiary Aircraft. The acquisition
was a merger accounted for as a purchase. Caribe is an FAA-licensed repair
station. Aircraft manufactures plastic cabin interior replacement parts and
refurbishes aircraft interior components. The purchase price paid to acquire
Caribe and Aircraft was approximately $23.3 million consisting of the
following: (i) $5.0 million in cash; (ii) $5.0 million in the form of
promissory notes payable over two years; and (iii) $5.7 million in shares of
AVS's authorized but unissued common stock (182,143 shares), and (iv) the
repayment of approximately $7.6 million of Caribe's and Aircraft's indebtedness
due to a financial institution. The operations of Caribe and Aircraft will be
included in AVS's consolidated financial statements from the date of
acquisition. Caribe and Aircraft had consolidated fiscal 1997 revenues of
approximately $27.0 million. The pre-acquisition operations of Caribe are not
material to the operations of AVS.


     A key element of AVS's strategy involves growth through the acquisition of
additional inventories of aircraft spare parts and the acquisition of other
companies, assets or product lines that would complement or expand AVS's
existing business. AVS's ability to grow by acquisition is dependent upon, and
may be limited by, the availability of suitable aircraft parts inventories,
acquisition candidates and capital, and by restrictions contained in AVS's
credit agreements. In addition, acquisitions involve risks that could adversely
affect AVS's operating results, including the assimilation of the operations
and personnel of acquired companies, the potential amortization of acquired
intangible assets and the potential loss of key employees of acquired
companies. There can be no assurance that AVS will be able to consummate
acquisitions on satisfactory terms.


RESULTS OF OPERATIONS


     Operating revenues consist primarily of gross sales, net of allowances for
returns. Cost of sales consists primarily of product costs, freight charges,
commissions to outside sales representatives and an inventory provision for
damaged and obsolete products. Product costs consist of the acquisition cost of
the products and any costs associated with repairs, overhaul or certification.


     Operating revenues and gross profit depend in large measure on the volume
and timing of bookings received during the quarter and the mix of aircraft
spare parts contained in AVS's inventory. Revenues and gross profit can be
impacted by the timing of bulk inventory purchases. In general, bulk inventory
purchases allow AVS to obtain large inventories of aircraft spare parts at a
lower cost than can ordinarily be obtained by purchasing such parts on an
individual basis.


     AVS's operating results are affected by many factors, including the timing
of orders from large customers, the timing of expenditures to purchase
inventory in anticipation of future sales, the timing of bulk inventory
purchases and the mix of available aircraft spare parts contained, at any time,
in AVS's inventory. A large portion of AVS's operating expenses are relatively
fixed. Since AVS typically does not obtain long-term purchase orders or
commitments from its customers, it must anticipate the future volume of orders
based upon the historic purchasing patterns of its customers and upon its
discussions with its customers as to their future requirements. Cancellations,
reductions or delays in orders by a customer or group of customers could have a
material adverse effect on AVS's business, financial condition and results of
operations.

</TABLE>

     First quarter operating revenues rose 50.3% to $82.5 million, compared
with $54.9 million for the same period last year. On March 6, 1998 AVS acquired
Caribe and its wholly-owned subsidiary, Aircraft. The post-acquisition
operations of Caribe and Aircraft have been included in the accompanying
condensed consolidated financial statements from the date of acquisition. As a
result of the Caribe and Aircraft acquisition, AVS's operating revenues
increased approximately $2.2 million from the date of the acquisition through
March 31, 1998. Kratz-Wilde, which was acquired during the fourth quarter of
1997 and accounted for using the purchase method of accounting, generated
approximately $10.5 million in revenue during the first quarter of 1998.
Operating revenues also increased due to increased customer penetration,
increased sales due to AVS's investment in and availability of increased
amounts of inventory and the continued expansion of inventory management
services being offered to and utilized by AVS's customers.


     Gross profit increased 62.8% to $24.6 million for the quarter ended March
31, 1998, compared with $15.1 million for the same period last year. Gross
profit margin increased to 29.8% for the first quarter of 1998, from 27.5% for
the first quarter of 1997. The increase in gross profit margin compared to 1997
was due primarily to a slightly different mix of products and services
delivered in each of the respective periods and remains in line with the 29.8%
gross profit margin reported for the fourth quarter of 1997.


     AVS's operating expenses increased 54.2% to $13.9 million in the first
quarter of 1998, compared with $9.0 million in the first quarter of 1997, due
to higher sales levels resulting in higher selling and operating expenses.
Operating expenses as a percentage of operating revenues increased to 16.9% in
the first quarter of 1998 from 16.4% in the corresponding period of 1997 due,
in large measure, to the approximately $.53 million in legal and professional
fees incurred during the period in connection with AVS's contemplated
acquisition of Whitehall. Without these expenses, operating expenses as a
percentage of operating revenues for the first quarter of 1998 would have been
16.2%.


                                       41
<PAGE>

     Interest expense, net increased by $2.6 million from period to period due
to net borrowings of $142.3 million during the last nine months of 1997 and the
first three months of 1998 to finance the acquisitions of Kratz-Wilde and
Caribe, inventory acquisitions and acquisitions of spare parts and engines held
for lease.


     As a result of the above factors, income before income taxes and
extraordinary item increased $2.1 million, or 40.8%, from $5.0 million in the
first quarter of 1997 to $7.1 million in the first quarter of 1998.


     In connection with the repayment of the term and acquisition portions of
the Credit Facility utilizing the proceeds of AVS's Senior Subordinated Notes
due 2008, AVS wrote off, during the first quarter of 1998, $1.0 million of
deferred financing costs resulting in an extraordinary item, net of income
taxes, of $.6 million.


     After accounting for income taxes and the extraordinary item, net income
for the three months ended March 31, 1998 was $3.8 million ($0.39 per diluted
share) compared to net income of $3.0 million ($0.32 per diluted share) for the
three months ended March 31, 1997. Weighted average common and common
equivalent shares outstanding (diluted) were 9.59 million during the three
months ended March 31, 1998, compared with 9.46 million for the three months
ended March 31, 1997.

     AVS's operating revenues increased by approximately $95.0 million, or
58.6%, from 1996 to 1997. Of this amount, approximately $33.1 million was
derived from the operations associated with Aerocell, Kratz and Apex, all of
which were acquired during 1997. Operating revenues also increased due to the
inclusion during 1997 of a full year of Dixie's sales (Dixie was acquired on
August 9, 1996), increased revenues from leasing activities, increased customer
penetration, increased sales due to AVS's investment in and availability of
increased amounts of inventory and the continued expansion of inventory
management services being offered to and utilized by AVS's customers. During
this period, domestic sales increased 90.2% from $94.6 million to $179.9
million and international sales increased 14.4%, from $67.3 million to $77.0
million.

     AVS's gross profit increased 47.7%, from $51.6 million in 1996 to $76.2
million in 1997. Gross margin declined from 31.9% in 1996 to 29.7% in 1997. The
decline in gross profit margin was expected as the mix of inventories sold
during 1997 continued to reflect a declining contribution from bulk inventories
acquired prior to 1995 and an increase in revenues from AVS's lower margin
bearings distribution business acquired in August 1996.


     AVS's operating expenses for 1997, in absolute dollars, increased $11.9
million, or 40.6%, compared to 1996. Approximately $4.4 million of the increase
is attributable to the operating expenses of Aerocell, Kratz and Apex, with the
balance attributable to higher sales levels resulting in higher selling and
operating expenses and increased reserves, offset in part by a $2.6 million
gain on a legal settlement with a former employee and stockholder. Primarily
due to economies of scale and improved operating efficiencies, operating
expenses as a percentage of revenue decreased from 18.1% in 1996 to 16.1% in
1997. See Note 7 to Notes to AVS's Consolidated Financial Statements.


     Interest expense, net increased $2.1 million, or 38.9% from 1996 to 1997
primarily due to the increase in borrowings necessary to fund AVS's growth.


     As a result of the above factors, income before income taxes and
extraordinary item increased $10.6 million, or 62.8%, from 1996 to 1997.


     Income taxes for 1996 were offset by one-time deferred tax benefits of
approximately $4.9 million associated with the organization of AVS. See Notes 1
and 11 to Notes to AVS's Consolidated Financial Statements. No such tax benefit
was realized in 1997.


     In connection with the IPO, AVS repaid certain debt. As a result, during
1996 AVS wrote-off approximately $3.1 million in deferred financing costs
relating to that debt, which resulted in an extraordinary item, net of taxes,
of approximately $1.9 million. See Note 5 to Notes to AVS's Consolidated
Financial Statements.

</TABLE>

     AVS's operating revenues increased by approximately $48.1 million, or
42.3%, from 1995 to 1996. Of this amount, approximately $16.3 million was
derived from the operations associated with AvEng and Dixie, both of which were
acquired during 1996. The balance represents increased sales due to the
expansion of AVS's customer base and increased sales to existing customers.
During this period, domestic sales increased 39.1% from $68.0 million to $94.6
million and international sales increased 47.3%, from $45.7 million to $67.3
million.


     AVS's gross profit increased 21.4%, from $42.5 million in 1995 to $51.6
million in 1996. The increase in gross profit is primarily attributable to the
increase in sales. Gross margins decreased from 37.3% in 1995 to 31.9% in 1996
due to a change in the mix of inventories sold. Due to the acquisition of ASC
in December 1994, AVS's gross profit was benefited by the impact of this bulk
inventory acquisition throughout 1995. No such acquisition of inventory
favorably benefited gross margins during 1996.


     AVS's operating expenses for 1996, in absolute dollars, increased $5.4
million, or 22.5%, compared to 1995 (of which approximately $1.5 million of the
increase is attributable to the operating expenses of AvEng and Dixie during
1996 and the balance is attributable to AVS's existing operations). Primarily
due to economies of scale and improved operating efficiencies, total operating
expenses as a percentage of revenue decreased from 21.0% in 1995 to 18.1% in
1996.


     Interest expense, net decreased $2.9 million, or 35.4% from 1995 to 1996
as a result of the repayment and restructuring of AVS's credit facility during
1996.


     As a result of the above factors, income from operations (before income
tax (benefit) expense and extraordinary item) increased $6.6 million, or 64.6%,
from 1995 to 1996.


     Income taxes for 1996 were offset by one-time deferred tax benefits of
approximately $4.9 million associated with the organization of AVS. See Notes 1
and 11 to Notes to AVS's Consolidated Financial Statements.


                                       44
<PAGE>

     Based on all of the above factors, AVS's 1996 net income was $17.4
million, or $2.22 per share, an increase of $7.1 million, or 68.8 %, compared
to 1995 income before extraordinary item of $10.3 million.


     In connection with the IPO, AVS repaid certain debt. As a result, during
1996 AVS wrote-off approximately $3.1 million in deferred financing costs
relating to that debt, which resulted in an extraordinary item, net of taxes,
of approximately $1.9 million. See Note 5 to AVS's Consolidated Financial
Statements.


LIQUIDITY AND CAPITAL RESOURCES


     Cash used in operations during the three months ended March 31, 1997 and
1998 was $9.6 million and $31.9 million, respectively. Cash used in investing
activities during the three month periods ended March 31, 1997 and 1998 was
$2.1 million and $10.6 million, respectively. During the three month periods
ended March 31, 1997 and 1998, AVS financed its operating and investing
activities primarily with its cash flow from financing activities, amounting to
$11.4 million and $42.6 million, respectively.


     Cash provided by operations was $14.0 million for the year ended December
31, 1995. Cash used in operations was $8.0 million and $48.8 million for the
years ended December 31, 1996 and 1997, respectively. Cash used in investing
activities for the years ended December 31, 1995, 1996 and 1997 was $4.7
million, $17.8 million and $54.8 million, respectively. Cash provided by
financing activities was $26.8 million and $107.4 million for the years ended
December 31, 1996 and 1997, respectively. Cash used in financing activities for
the year ended December 31, 1995 was $10.5 million.


     AVS and its subsidiaries have entered into the Credit Facility with
certain financial institutions. At present, the Credit Facility consists of a
$91.4 million revolving loan and letter of credit facility, subject to an
availability calculation based on the eligible borrowing base (the "Revolving
Credit Facility"). The eligible borrowing base includes certain receivables and
inventories of AVS. The letter of credit portion of the Revolving Credit
Facility is subject to a $15.0 million sublimit, with the imposition of certain
borrowing criteria based on the satisfaction of certain debt ratios. The
interest rate on the Credit Facility is, at the option of AVS, (a) prime plus a
margin, or (b) LIBOR plus a margin, where the margin determination is made
based upon AVS's financial performance over a 12 month period (ranging from
0.0% to 1.25% in the event prime is utilized, or 1.50% to 2.75% in the event
LIBOR is utilized). At March 31, 1998, the margin was .25% for prime rate loans
and 1.75% for LIBOR rate loans.


     The Credit Facility contains certain financial covenants regarding the
financial performance of AVS and certain other covenants, including limitations
on the amount of annual capital expenditures and the incurrence of additional
debt, and provides for the suspension of the Credit Facility and repayment of
all debt in the event of a material adverse change in the business or a change
in control. In addition, the Credit Facility requires mandatory repayments from
the proceeds of a sale of assets or an issuance of equity or debt securities or
as a result of insufficient collateral to meet the borrowing base requirements
thereunder. Substantially all of AVS's assets are pledged as collateral for
amounts borrowed. The Revolving Credit Facility will terminate on July 31,
2002. At March 31, 1998, AVS was in compliance with all covenants of the Credit
Facility and $25.2 million was outstanding under the Credit Facility.


     On February 17, 1998, AVS sold $165 million in senior subordinated notes
(the "Notes") due in 2008 with a coupon rate of 8.125% at a price of 99.395%.
Proceeds were used to repay amounts outstanding under the Credit Facility
(including amounts due under a $58.6 million term loan facility) and to fund
the cash requirements relating to the acquisition of Caribe and Aircraft.


     The Notes mature on February 15, 2008. Interest is payable on February 15
and August 15 of each year, commencing August 15, 1998. The Notes are general
unsecured obligations of AVS, subordinated in right of payment to all existing
and future senior debt of AVS, including indebtedness outstanding under the
Credit Facility and under facilities which may replace the Credit Facility in
the future. In addition, the Notes are effectively subordinated to all secured
obligations to the extent of the assets securing such obligations, including
the Credit Facility. The indenture pursuant to which the Notes have


                                       45
<PAGE>

been issued (the "Indenture") permits AVS and its subsidiaries to incur
additional indebtedness, including Senior Debt, subject to certain limitations.
The Notes are also effectively subordinated in right of payment to all existing
and future liabilities of any subsidiaries of AVS which do not guarantee the
Notes.


     The Notes are unconditionally guaranteed, on a senior subordinated basis,
by substantially all of AVS's existing subsidiaries and each subsidiary that
will be organized in the future by AVS, unless such subsidiary is designated as
an unrestricted subsidiary (the "Subsidiary Guarantors"). Subsidiary Guarantees
are joint and several, general unsecured obligations of Subsidiary Guarantors.
Subsidiary Guarantees are subordinated in right of payment to all existing and
future Senior Debt of Subsidiary Guarantors, including the Credit Facility, and
are also effectively subordinated to all secured obligations of Subsidiary
Guarantors to the extent of the assets securing such obligations, including the
Credit Facility. Furthermore, the Indenture permits Subsidiary Guarantors to
incur additional indebtedness, including senior debt, subject to certain
limitations.


     The Notes are redeemable, at the option of AVS, in whole or in part, at
any time after February 15, 2003, at the following redemption prices, plus
accrued and unpaid interest and liquidated damages, if any, to the redemption
date: (i) 2003--104.063%; (ii) 2004--102.708%; (iii) 2005--101.354%; and (iv)
2006 and thereafter--100%. In addition, on or prior to February 15, 2001, AVS
may redeem up to 35% of the aggregate principal amount of the Notes at a
redemption price of 108.125% of the principal amount thereof, plus accrued and
unpaid interest and liquidated damages, if any, thereon to the redemption date
with the net proceeds of a public offering of common stock of AVS; provided,
that at least 65% of the aggregate principal amount of the Notes originally
issued remains outstanding immediately after the occurrence of such redemption.
 


     Upon the occurrence of a change of control, AVS will be required to make
an offer to repurchase all or any part of holder's Notes at a repurchase price
equal to 101% of the principal amount thereof, plus accrued and unpaid interest
and liquidated damages, if any, thereon to the repurchase date. There can be no
assurance that AVS will have the financial resources necessary to purchase the
Notes upon a change of control or that such repurchase will be permitted under
the Credit Facility.


     The Indenture contains certain covenants that, among other things, will
limit the ability of AVS and its subsidiaries to incur additional indebtedness
and issue preferred stock, pay dividends or make other distributions, make
investments, dispose of assets, issue capital stock of subsidiaries, create
certain liens securing indebtedness, enter into certain transactions with
affiliates, sell assets or enter into certain mergers and consolidations or
sell all or substantially all of their assets.


     Pursuant to a registration rights agreement, AVS has agreed to (a) file a
registration statement on or prior to April 3, 1998 with respect to an offer to
exchange the Notes for a new issue of debt securities of AVS registered under
the Securities Act with terms substantially identical to those of the Notes
(the "Exchange Offer") which registration statement was filed on March 26, 1998
and (b) use their best efforts to cause the registration statement to be
declared effective by the Securities and Exchange Commission on or prior to
June 17, 1998. AVS has also agreed to file a shelf registration statement
relating to the resale of the Notes under certain circumstances. If AVS fails
to satisfy these registration obligations, it will be required to pay
liquidated damages to holders of Notes under certain circumstances.


     On August 5, 1997, a subsidiary of AVS, Aviation Sales SPS I, Inc.,
entered into a term loan agreement in a principal amount of $7.2 million which
was guaranteed by AVS, to finance certain equipment and rotable parts on
long-term lease, which secure the loan. This loan is payable in 59 consecutive
equal monthly payments of $91,750 commencing September 14, 1997, with a final
balloon payment due on August 14, 2002. Interest on this term loan is fixed at
8.21%. AVS has leased the underlying equipment and rotable parts to unrelated
third parties. Interim payments under the term loan will be made from the
proceeds of these parts leases. This term loan contains financial and other
covenants and mandatory prepayment events, as defined. At March 31, 1998, AVS
was in compliance with all covenants of this term loan.


                                       46
<PAGE>

     In connection with its acquisition of Kratz-Wilde Machine Company
AVS/Kratz-Wilde Machine Company, a subsidiary of AVS, delivered a non-interest
bearing promissory note in the original principal amount of $2.2 million, which
was guaranteed by AVS, to the seller. At March 31, 1998, AVS was in compliance
with the terms of this promissory note.


     In connection with its acquisition of Caribe, on March 6, 1998 Aviation
Sales Manufacturing & Repair Company, a subsidiary of AVS, delivered a
promissory note in the original principal amount of $5.0 million, which was
guaranteed by AVS, to the seller. The note is payable over a two year period
with interest at the rate of 8% per annum.


     During the three month period ended March 31, 1998 and the years ended
December 31, 1995, 1996 and 1997, AVS incurred capital expenditures of
approximately $4.1 million, $0.9 million, $1.1 million and $4.4 million,
respectively, primarily to make enhancements to AVS's management information
systems, telecommunications systems and other capital equipment and
improvements. AVS's current management information system is not Year 2000
compliant. AVS is currently implementing a new management information system,
which among other things, management believes will allow AVS to continue to
maintain its competitive advantage resulting from the availability of
information regarding its market and will mitigate the Year 2000 issues
currently inherent in AVS's existing system. The cost of the new MIS system is
expected to be approximately $8.0 million, which will be incurred over
approximately a two year period. Financing for the new system will be provided
from operations and from borrowings under the Credit Facility.


     As part of its growth strategy, AVS intends to continue to pursue
acquisitions of bulk inventories of aircraft spare parts and complementary
businesses. Additionally, AVS is actively considering the prospect of
consolidating its various facilities into a single warehouse facility.
Financing for such activities would be provided from operations and from
borrowings under the Credit Facility. AVS may also in the future issue
additional debt and/or equity securities in connection with financing one or
more of its activities. AVS believes that cash flow from operations and
borrowing availability under the Credit Facility will be sufficient to satisfy
AVS's anticipated working capital requirements over the next twelve months.

                             WHITEHALL'S BUSINESS


GENERAL


     Whitehall is an independent provider of maintenance and modification for
commercial, military and freighter aircraft. Whitehall focuses primarily on two
categories of commercial customers: established traditional commercial carriers
that view outsourcing as a way to reduce operating expenses and increase their
competitiveness and new entrant, low-cost air carriers that rely on outsourcing
for scheduled heavy maintenance. Whitehall operates two FAA and JAA certified
repair stations that specialize in heavy maintenance and modification of Boeing
707, 727, 737, McDonnell Douglas DC-8, DC-9, DC-10 and Lockheed L-100, L-188
and C-130 aircraft. Whitehall offers its customers a comprehensive range of
aviation services, including scheduled "A," "B," "C" and "D" level inspections,
block overhauls and repairs, corrosion prevention and control programs and
exterior stripping and painting. Modification services provided by Whitehall
include interior reconfiguration, cargo conversions and avionics installations.
Through a joint venture, Whitehall also designs, and markets hushkits designed
to reduce the noise created by Boeing 737-100 and 737-200 series aircraft to
levels which comply with FAA-mandated Stage 3 noise reduction standards.


RECENT DEVELOPMENTS


     In July 1997, Whitehall purchased from Zantop International Airlines, Inc.
("Zantop") certain assets (the "Acquired Assets") used in connection with the
operation of Zantop's third party aircraft maintenance business located in
Macon, Georgia. Among the Acquired Assets were all of the Zantop's leasehold
interests in the properties located at its Macon facility (the "Leased
Facilities"). The purchase price for the Acquired Assets was $1.5 million in
cash plus the assumption of certain liabilities, including approximately $4.3
million in future lease obligations relating to the Leased Facilities.


     In April 1997, the United States Air Force ("USAF") awarded Whitehall a
five-year contract (the "C-130 Contract") to perform Programmed Depot
Maintenance on its fleet of C-130 cargo aircraft stationed in the continental
United States. In June 1997, the C-130 Contract was canceled at the convenience
of the U.S. government because the USAF elected to perform this work with
government personnel at two of its remaining USAF bases rather than outsourcing
it to private contractors. The C-130 Contract provides for reimbursement by the
USAF of costs incurred by Whitehall during its term. Whitehall has made a claim
for reimbursement and is currently negotiating a settlement with the USAF for
the claimed amount.


     In March 1997, Whitehall sold its electronics business to a private
investor group (the "Crystek Buyer") for approximately $2.7 million. The
transaction was structured as a sale by Whitehall of all of the outstanding
capital stock of Crystek Crystals Corporation, Whitehall's electronics division
operating subsidiary ("Crystek"). Whitehall received approximately $1.9 million
in cash and two promissory notes aggregating $864,000. The promissory notes are
due in installments from 1998 through 2001 and bear interest at a rate of 10%
per annum. Under the terms of the agreement relating to the sale of Crystek
(the "Crystek Agreement"), Whitehall agreed to remediate certain environmental
conditions on the real property owned by Crystek (the "Crystek Property") and,
if such environmental conditions are not satisfactorily remediated by December
31, 1998, the Crystek Buyer has the right to require Whitehall to repurchase
the Crystek Property on the terms and subject to the conditions set forth in
the Crystek Agreement. In the event of such a sale, the Crystek Buyer will have
the right to lease the Crystek Property from Whitehall.


     In November 1996, Whitehall sold its ocean systems business to a
newly-formed company, Hydroscience Technologies, Inc. ("HTI"), in exchange for
818,182 shares of preferred stock of HTI (the "HTI Preferred Stock") and the
limited assumption by HTI of potential warranty liabilities associated with
such business. The aggregate amount of HTI Preferred Stock received by
Whitehall was equal to the book value of the assets transferred by it to HTI.
The HTI Preferred Stock carries a liquidation preference of $5.50 per share. At
Whitehall's election, the HTI Preferred Stock is convertible into 45%


                                       48
<PAGE>

of the common stock of HTI. Whitehall has concluded that the value of its
investment in the HTI Preferred Stock has declined permanently. The entire
amount was written off in September 1997.


INDUSTRY OUTLOOK


     GENERAL. Whitehall believes that the total market for commercial airframe
heavy maintenance and modification services in North America is approximately
$2.3 billion annually. Approximately 65% of these services are currently being
performed by airlines themselves, with the remaining demand being outsourced to
independent providers such as Whitehall. As the commercial airline industry
continues to operate under intense competition and federal budgetary
constraints force reductions in military spending, management believes that
both the private and military sectors will increasingly view outsourcing as a
logical and effective way to reduce operating costs. Factors which management
believes indicate the strength of the demand for its services include (i) the
projected growth of worldwide air traffic, (ii) the proliferation of start-up
airlines which typically depend on outside facilities for maintenance, (iii)
the desire of established airlines to reduce costs by divesting themselves of
large segments of their maintenance operations and shifting these
responsibilities to third-party providers who are often able to provide these
services more quickly and less expensively, (iv) the growth of the worldwide
air cargo industry which Whitehall believes will foster the demand for
passenger-to-freighter modification services, and (v) the current policy of the
United States military to promote outsourcing to the private sector many of the
services that were traditionally provided internally.


     COMMERCIAL MAINTENANCE MARKET. The growth of the worldwide commercial
aircraft maintenance market is greatly affected by worldwide air travel.
According to the Boeing Report, world air travel is expected to grow at a
compound annual rate of 5.5% for the next ten years. During that same period,
the worldwide fleet of commercial airplanes is expected to increase by
approximately 48%. Further, deregulation of the aviation industry in the United
States and the European Economic Community, increased demand for low-fare air
travel and relatively low barriers to entry have led to the emergence of
several start-up airlines. Approximately 92% of the aircraft operators
worldwide have fleets of less than 30 aircraft. For these carriers, in-house
maintenance capabilities are not generally considered to be economically
viable. In addition, a number of established airlines have begun to view
maintenance outsourcing as a way to increase productivity of their assets,
reduce operating costs and better focus their resources on their core
competencies of transporting passengers and freight.


     COMMERCIAL MODIFICATION MARKET. Whitehall expects the airframe
modification business to experience growth over the next several years,
primarily due to the rapid expansion of the global air freight industry and the
phase in of federal noise control legislation requiring airlines to either
modify or remove from their U.S. fleet certain aircraft models by the end of
1999. As the worldwide freight transport market continues to grow, so does the
demand for dedicated cargo aircraft. According to the Boeing Report, air cargo
traffic is projected to increase at a compound annual rate of 6.6% through 2016
and an additional 420 dedicated freighter aircraft are expected to be added to
the world fleet during that period. Because few cargo carriers are willing to
commit the capital to purchase newly built cargo aircraft, it is expected that
the majority of the dedicated freighter aircraft coming into circulation in the
next several years will be passenger aircraft which have been modified and
converted for cargo duty.


     The Airport Noise and Capacity Act of 1990 ("ANCA") requires the phaseout
of Stage 2 aircraft (defined as aircraft that comply with the Stage 2 noise
levels prescribed in Part 36 of the Federal Aviation Regulations) by December
31, 1999, subject to certain exceptions. The FAA regulations which implement
the ANCA require carriers to modify or reduce the number of Stage 2 aircraft
operated by 75% by the end of 1998 and 100% by the end of 1999. Alternatively,
a carrier could satisfy these compliance requirements by phasing in aircraft
meeting the stricter Stage 3 requirements (set forth in Part 36 of the Federal
Aviation Regulations) so that its fleet has at least 75% Stage 3 aircraft by
the end of 1998 and 100% of Stage 3 aircraft by the end of 1999. Certain types
of Stage 2 aircraft can be modified to meet Stage 3 requirements by installing
a hushkit to the aircraft's engine. AvAero Noise Reduction Joint Venture
("AvAero"), a joint venture in which Whitehall holds a 40% interest, designs


                                       49
<PAGE>

and markets FAA-certified hushkits for Boeing 737-100 and 737-200 series
aircraft. AvAero's other venturers are Avro Corp., which holds a 40% interest,
and WDW Aviation Management, Inc., which holds a 20% interest.


     MILITARY MAINTENANCE AND MODIFICATION MARKET. The U.S. military has also
turned to outsourcing in an effort to reduce costs in a shrinking budgetary
environment. Currently, U.S. military and government civilian personnel perform
approximately 72% and 64% of the aircraft maintenance for the USAF and United
States Navy ("Navy"), respectively. Several factors suggest that a greater
percentage of this work may be outsourced in the future. Budget constraints
have led to a reduction in the number of military and government civilian
personnel in each branch of the U.S. military. The Navy is considering closing
three of its six naval aviation depots, however the number of its aircraft to
be maintained is expected to be reduced by only 25%. The USAF has moved to
"privatize in place" rather than close down its Kelly and McClellen bases.
Private contractors have submitted proposals to perform the work on site at
these bases and to employ many of the former government workers. The reduction
in the government's internal capacity to provide military aircraft maintenance
and modification services has not been accompanied by a corresponding reduction
in demand for these services. The current U.S. policy favoring the rapid
deployment of forces as opposed to maintaining numerous overseas military bases
relies heavily on the ability to quickly airlift personnel and equipment to
areas requiring military or humanitarian intervention. Accordingly, the need
for maintenance, modification and life extension programs for a substantial
portion of the U.S. military air fleet is expected to continue. Under the
so-called "60-40 law," the military was limited in the amount of depot level
aircraft maintenance work it was permitted to transfer to the private sector to
40% of its overall depot level maintenance requirements. On November 18, 1997,
the National Defense Authorization Act for Fiscal 1998 increased this amount to
50%. Although the recent change in law and current trend towards outsourcing by
the U.S. military should result in greater opportunities for independent
maintenance providers such as Whitehall, there can be no assurance that
Whitehall will be successful in obtaining any future U.S. military contracts.


PRINCIPAL PRODUCTS AND SERVICES


     COMMERCIAL MAINTENANCE SERVICES. The principal services performed by
Whitehall are scheduled "A," "B," "C" and "D" level maintenance checks. Each
involves a different degree of inspection and the services performed at each
level vary depending upon the individual aircraft operator's FAA-certified
maintenance program. The "A" and "B" level checks involve the fewest required
procedures and often can be completed within a few days. The "C" and "D" level
checks are more comprehensive and usually take several weeks to complete,
depending upon the scope of the work to be performed.


     The "C" level check is an intermediate level service inspection that
typically includes a thorough cleaning of the aircraft's exterior, testing and
lubrication of its operational systems, filter servicing and limited cleaning
and servicing of the interior. Trained mechanics perform a visual inspection of
the external structure and internal structure through access panels. The "D"
level check includes all of the work accomplished in the "C" level check but
places a more detailed emphasis on the integrity of the systems and structural
functions. In the "D" level check, the aircraft is disassembled to the point
where the entire structure can be inspected and evaluated. Once the evaluation
and repairs are completed, the aircraft and its systems are reassembled to the
detailed tolerances demanded in each system's specifications. Depending upon
the type of aircraft and the FAA-certified maintenance program being followed,
intervals between "C" level checks can range from 1,000 to 5,000 flight hours
and intervals between "D" level checks can range from 10,000 to 25,000 flight
hours.


     Structural inspections performed during "C" level and "D" level checks
provide Whitehall personnel with detailed information about the condition of
the aircraft and the need to perform additional work or repairs not provided
for in the original workscope. Project coordinators and customer support
personnel work closely with the aircraft's customer service representative in
evaluating the scope of any additional work required and in the preparation of
a detailed cost estimate


                                       50
<PAGE>

for the labor and materials required to complete the job. Upon receipt of the
customer representative's approval of the estimate, Whitehall releases the
requisitions and work orders into the work flow for the aircraft.


     Other maintenance services offered to commercial customers include
Supplemental Structure Inspections ("SSI's") and Corrosion Prevention and
Control Programs ("CPCP's"). SSI's are structural inspections which focus on
known problem areas and are required by most aircraft manufacturers. CPCP's are
also an outgrowth of manufacturer-required Aging Aircraft Programs and involve
the inspection and treatment of areas with known corrosion problems. These
additional inspections often supplement the "C" and "D" level check tasks.


     COMMERCIAL MODIFICATION SERVICES. Each aircraft certified by the FAA is
constructed under a "Type Certificate." Anything which is done subsequently to
modify the aircraft from its original specifications requires the review,
flight-testing and approval of the FAA which is evidenced by the issuance of a
Supplemental Type Certificate ("STC") for that particular modification. Typical
modification services performed by Whitehall include refurbishing and
reconfiguring passenger seating, installing passenger amenities such as
telephones and video screens and converting traditional passenger cabins into
amenity filled "VIP" quarters.


     The process of converting a passenger plane to freighter configuration
entails completely stripping the interior; strengthening the load-bearing
capacity of the flooring; installing the bulkhead or cargo net; cutting into
the fuselage for the installation of a large cargo door; reinforcing the
surrounding structures for the new door; replacing windows with metal plugs;
and fabricating and installing the cargo door itself. The aircraft interior may
also need to be lined to protect cabin walls from pallet damage and the air
conditioning system may have to be modified. Conversion contracts also
typically require "C" or "D" level maintenance checks as these converted
aircraft have often been out of service for some time and maintenance is
required for the aircraft to comply with current FAA standards.


     Whitehall owns a 40% interest in AvAero, a joint venture that designs and
markets hushkits for Boeing 737-100 and 737-200 series aircraft. The AvAero
hushkit weighs approximately 500 pounds at its heaviest configuration and fits
a wide range of engine models and aircraft weights. Major airlines have cited
its design simplicity, ease of installation, performance and absence of
operational restrictions as major factors in selecting the AvAero hushkit over
competing models. In January 1997, AvAero was selected by Southwest Airlines
("Southwest") to provide hushkits for up to 34 of Southwest's Boeing 737
aircraft. The agreement with Southwest provides for the delivery of 20 hushkits
beginning in June 1997 and an option to purchase an additional 14 hushkits.


     Additional modification services performed by Whitehall include cockpit
reconfiguration and the integration of Traffic Control and Avoidance Systems
("TCAS"), windshear detection systems and navigational aids.


     MILITARY MAINTENANCE AND MODIFICATION SERVICES. Whitehall provides
aircraft maintenance and modification services to the U.S. military and the
military branches of certain foreign governments. Whitehall specializes in
providing Programmed Depot Maintenance ("PDM") on large transport planes used
to move troops, supplies and equipment, such as the C-130 "Hercules." The PDM
program involves a nose to tail inspection and repair program. It begins with
the defueling of the aircraft and the stripping of its exterior paint. Trained
mechanics then perform a section-by-section structural examination of the
entire aircraft which can result in modifications to the airframe. Avionics are
inspected and repaired, replaced or modified as needed. Corrosion prevention
and control measures and various system overhauls or upgrades may also be
performed. At the completion of the overhaul, the aircraft is repainted.


     On April 15, 1997, Whitehall was awarded the C-130 Contract by the USAF.
It provided for the furnishing of PDM on the USAF's C-130 aircraft stationed in
the continental United States. In June 1997, the C-130 Contract was canceled at
the convenience of the U.S. government because the USAF


                                       51
<PAGE>

elected to perform this work with government personnel at two of its remaining
USAF bases rather than outsourcing it to private contractors. The C-130
Contract provides for reimbursement by the USAF of costs incurred by Whitehall
during its term. Whitehall has made a claim for reimbursement and is currently
negotiating a settlement with the USAF for the claimed amount.


     Whitehall is currently performing C-130 PDM work for the government of
Mexico and continues to bid for similar work for aircraft owned and operated by
certain other foreign governments.


PRICING


     Whitehall's services are offered to commercial customers on a contract
basis. Customers are generally offered either time and material based
arrangements or flat rate fixed price arrangements. Under the time and
materials fee arrangement, customers receive a detailed price estimate and
condition report from Whitehall after a thorough inspection of the aircraft.
Following the approval by the customer of the estimate, Whitehall issues work
orders and requisitions for the customer's aircraft. Customer support personnel
closely monitor the progress of the aircraft and negotiate with the customer
any additional pricing, scheduling and logistical issues which arise during the
course of servicing. Most of the aircraft serviced by Whitehall are priced on a
time and material based arrangement.


     Under the flat rate fixed pricing contracts, Whitehall establishes a set
price prior to undertaking a maintenance or modification project based upon
estimates made either before or after inspection of the aircraft. Whitehall's
flat rate fixed price estimates made prior to inspection of an aircraft are
based upon standard labor and materials requirements and typically include
provisions for adjustments based upon condition of the aircraft.


     The U.S. military contracts for which Whitehall competes are awarded on a
competitive bid basis. The contracts are typically firm agreements to provide
specified aviation services at a fixed rate. They typically have terms of one
year subject to annual renewals at the option of the contracting agency.


MANAGEMENT INFORMATION SYSTEM


     Whitehall has developed an advanced integrated management information
system which allows management and customers to track the progress of every
aircraft being serviced on a real time basis. Bar coded work task cards are
tracked electronically and help coordinate the work of each assigned mechanic
and quality control inspector. The system can be accessed from any one of more
than 200 display stations located throughout Whitehall's Lake City and Macon
facilities. Project coordinators can immediately access such detailed
information as the number of work-hours generated for any given project, a list
of all parts used or ordered and the identity of and tasks performed by each
mechanic and quality control inspector who has worked on an aircraft. This
information enables management to optimize the daily deployment of personnel,
materials and equipment among the various projects in service and to provide
customers with quick and accurate information about the status of their
aircraft.


COMPETITION


     The market for aircraft maintenance and modification services is highly
competitive and fragmented. In addition to several other independent
maintenance operators, Whitehall faces significant competition from major
commercial airlines that own and operate their own aircraft maintenance service
centers. In addition, the aircraft divisions of certain large OEMs have
announced their intention to enter this market. Such OEMs and airlines have
substantially greater financial resources than Whitehall. Whitehall does not
have data available to determine its exact relative market position. Whitehall
believes that the most important bases for competition in its industry are
dependability of performance, prompt turnaround time, price and flexibility.
Whitehall considers its competitive strengths to be the flexibility and
experience of its labor force, its efficient facilities and its reputation for
quality and on-time delivery. Whitehall's principal competitors for its
commercial work include


                                       52
<PAGE>

Tramco, Inc., Dee Howard Company, Mobile Aerospace, Inc., Triad International
Maintenance Corporation and Pemco World Air Services, Inc. Its principal
competitors for military contracts include Boeing Military Aircraft,
Lockheed-Martin Aeromod and Raytheon-E Systems.


CUSTOMERS


     Whitehall's commercial services are offered to the airline industry at
large, and in particular, to owners and operators of aircraft who do not have
maintenance facilities of their own or whose facilities are unable to
accommodate an increasing workload. These customers have historically included
many start-up passenger airlines and air cargo companies. Whitehall's customers
also include large, established air carriers who have turned to outsourcing
portions of their maintenance operations in an effort to increase their
profitability. During 1997, AirTran Holdings, Inc. (formerly, Valujet, Inc.)
accounted for approximately 23% of Whitehall's consolidated net sales, and the
top three customers of Whitehall (including AirTran) accounted for
approximately 49% of such sales. During 1996, three customers accounted for
approximately 26%, 15%, and 14% of Whitehall's consolidated net sales. During
1995, two customers accounted for 30% and 21% of Whitehall's consolidated net
sales. None of Whitehall's customers are contractually obligated to provide
Whitehall with any minimum number of aircraft for servicing in the future.
There can be no assurance that Whitehall's larger historical customers will
continue to utilize Whitehall's services to the same extent as they have in the
past. Whitehall's commercial customers include Continental Airlines, American
Trans Air, AirTran, Ryan International/Emery Worldwide, Burlington Air Freight,
and US Airways. Whitehall has also performed services under government
contracts for the USAF, the U.S. Coast Guard and the Mexican Air Force. The
U.S. government accounted for approximately 5% and 2% of Whitehall's 1997 and
1995 consolidated net sales, respectively. Whitehall made no sales to the U.S.
government in 1996.


REGULATION AND CERTIFICATION


     The maintenance, modification and operation of aircraft are strictly
regulated by the FAA and foreign aviation authorities which oversee such
matters as aircraft certification, inspection, maintenance, certification of
personnel and record keeping. FAA regulations are designed to insure that all
aircraft and aviation equipment are continuously maintained in proper condition
to ensure safe operation of the aircraft. Similar rules apply in most foreign
countries. All aircraft must be maintained under a continuous monitoring
program and must periodically undergo thorough inspection and maintenance. The
inspection, maintenance and repair procedures for the various types of aircraft
are prescribed by regulatory authorities and can be performed only by certified
repair facilities utilizing certified technicians. Whitehall operates
FAA-certified repair stations in Lake City, Florida and Macon, Georgia and has
been granted licenses from the FAA and several foreign regulatory counterparts,
including the JAA, to perform maintenance, repair and overhaul services on most
narrow-bodied aircraft and wide-bodied aircraft. Whitehall also employs a
dedicated staff of FAA-certified structural, electrical, avionics and Airframe
and Powerplant technicians.


     In addition to domestic and foreign governmental regulations, OEMs,
commercial airlines and other customers require that Whitehall satisfy certain
requirements relating to the quality of its services. The Coordinated Agency
for Supplier Evaluation ("CASE"), a consortium of United States air carriers,
reviews the operations of Whitehall on a regular basis for quality and
efficiency. Whitehall has completed several audits conducted by the FAA and
CASE and has continually met or exceeded the requirements imposed by its
customers and by OEMs.


     Whitehall's operations are also subject to a variety of worker and
community safety laws. The Occupational Safety and Health Act of 1970 ("OSHA")
mandates general requirements for safe workplaces for all employees. Specific
safety standards have been promulgated for workplaces engaged in the treatment,
disposal or storage of hazardous waste. Whitehall believes that its operations
are in material compliance with OSHA's health and safety requirements.


                                       53
<PAGE>

ENVIRONMENTAL MATTERS


     Whitehall's operations, like those of other companies engaged in similar
businesses, are subject to federal, state and local environmental laws and
regulation by government agencies, including the United States Environmental
Protection Agency ("EPA") and the Florida Department of Environmental
Protection ("FDEP"). Among other matters, these regulatory authorities impose
requirements that regulate the emission, discharge, generation, management,
transportation and disposition of hazardous materials, pollutants and
contaminants, govern public and private response actions to hazardous or
regulated substances which may be or have been released to the environment, and
require Whitehall to obtain and maintain licenses and permits in connection
with its operations. This extensive regulatory framework imposes significant
compliance burdens and risks on Whitehall.


     Whitehall periodically reviews its reserves for potential environmental
liabilities. Such review includes an evaluation of currently available facts
with respect to each individual site and consideration of factors such as
existing technology, current laws and regulations and Whitehall's prior
experience in remediation of contaminated sites. As assessments and remediation
efforts progress at individual sites, Whitehall's environmental reserves and
remediation plans are reviewed and adjusted to reflect the additional legal and
technical information as it becomes available.


     Whitehall is taking remedial action pursuant to EPA regulations at the
Lake City, Florida facility. Environmental testing continues to be performed at
this site and Whitehall is monitoring the results of such tests to assess the
impact and magnitude of Whitehall's required remediation efforts. Based upon
the most recent cost estimates provided by Whitehall's environmental
consultants, Whitehall believes that the total remaining remediation and
compliance costs at this facility will be approximately $2.4 million. There
are, however, other areas on the property at Lake City that could also require
remediation, although Whitehall does not believe it is responsible for such
areas. In the event remediation efforts are required in such areas, Whitehall
may be required to share in the costs of such remediation in order to continue
its operations at Lake City. Whitehall is unable to estimate the potential
amount of such costs at this time.


     In connection with the sale of Crystek, Whitehall was required to perform,
at its own expense, an environmental site assessment on the Crystek Property.
Whitehall is also required to remedy all recognized environmental conditions
identified in the assessment to bring the Crystek Property into compliance with
all applicable Federal, State and local environmental laws. If the facility is
not brought into compliance with such environmental laws by December 31, 1998,
the Crystek Buyer shall have the option of requiring Whitehall to repurchase
the Crystek Property. Whitehall has engaged independent environmental
consultants to review the potential environmental liabilities on the Crystek
Property. Such investigation and testing resulted in the identification of
likely environmental remedial actions. Based upon the cost estimates provided
by the consultants, Whitehall believes that the total remediation and
compliance costs for the Crystek Property will be approximately $1.0 million.


     Actual costs required to be incurred by Whitehall in the future for
environmental compliance and remediation may vary from Whitehall's current
estimates of such costs, primarily because of the inherent uncertainties in
evaluating environmental exposures. These uncertainties include the extent of
remediation based on testing and evaluation not yet completed, the varying
costs and effectiveness of remediation methods and potential changes in
environmental laws, regulations or the interpretations thereof. No assurance
can be given that actual amounts ultimately required to be expended by
Whitehall for environmental compliance and remediation in the future will not
be material.


MATERIALS


     Whitehall purchases components, parts and equipment from various
suppliers. Whitehall is not dependent upon any single supplier or group of
suppliers for any of the material it uses in its business and has encountered
no difficulties in purchasing sufficient quantities in the open market.


                                       54
<PAGE>

PATENTS, TRADEMARKS, LICENSES, FRANCHISES AND CONCESSIONS


     Whitehall holds no material patents, franchises or concessions.


EMPLOYEES


     As of December 31, 1997, Whitehall had approximately 1,152 full-time
employees. None of Whitehall's employees are covered by a collective bargaining
agreement. Whitehall believes that its relations with its employees are
generally good.

</TABLE>

Whitehall leases approximately 70,000 sq. ft. of the Dallas, Texas facility to
HTI.


     Whitehall's aircraft depot located at the Lake City Municipal Airport in
Lake City, Florida spans 120 acres and includes seven maintenance hangars, two
runways, over 1.3 million square feet of ramp space, an FAA-certified control
tower and a fuel farm. The seven clear span steel hangars provide over 650,000
square feet of covered space and can comfortably house up to 18 narrow-bodied
aircraft. There is also covered nose dock space which allows for the sheltered
maintenance of up to four additional aircraft. Six hangars are used for heavy
maintenance and modification and one hangar is dedicated for aircraft striping
and painting. Each hangar has its own technical library, customer
representative offices, tool rooms, storage rooms and a production control
center where all of the paperwork associated with a project's workscope is
maintained. Each of the hangars are in close proximity to one another and to
Whitehall's administrative offices and hydraulic and sheetmetal shops. The Lake
City facility is operated by Whitehall under a lease from the City of Lake City
which expires in 2022. Since 1992, Whitehall has invested more than $9.2
million to renovate and improve the Lake City facility to the point where it is
now capable of accommodating nearly all narrow-bodied and wide-bodied aircraft
in current production.


     Whitehall's Macon facility consists of five buildings on the east ramp of
the Macon Municipal Airport in Macon, Georgia. With over 140,000 square feet
under roof, the Macon facility can house three DC-8 and three DC-9 aircraft in
its hangar bays. One of its three hangar bays can also accommodate a DC-10 or
A-300 size aircraft.

     Whitehall believes that its plants and other physical properties are
adequate for its intended operations.


LEGAL PROCEEDINGS

     On May 10, 1991, an action was filed in the District Court of Dallas
County, Texas, by Lee D. Webster, former Chairman, Chief Executive Officer and
President of Whitehall, against Whitehall, each


                                       55
<PAGE>

of its directors (other than Mr. Webster) and Cambridge Capital, alleging,
among other things, that (i) the defendants' actions, both individually and in
concert, constituted willful interference with Mr. Webster's employment
relationship with Whitehall and was the direct cause of Mr. Webster's
termination as its President and Chairman of the Board, and (ii) the
defendants' actions forced Mr. Webster into retirement without providing Mr.
Webster with retirement benefits which Mr. Webster was purportedly promised. On
August 17, 1994, the defendants were granted a partial summary judgment. On
October 24, 1994, Mr. Webster filed a third amended petition and alleged the
following causes of action: tortuous interference with contractual relations
against Cambridge Capital Fund, L.P., and directors George F. Baker and John J.
McAtee; intentional infliction of emotional distress and breach of oral
contracts. The third amended petition sought compensatory and punitive damages
in excess of $35 million.


     On January 12, 1995, the Court entered an abatement on one of the breach
of oral contract claims against Whitehall and entered a summary judgment in the
defendants' favor on all remaining claims alleged by Mr. Webster. On February
26, 1996, the Court granted a summary judgment in favor of the defendants on
Mr. Webster's remaining claims and entered a take nothing final judgment which
dismissed all of Mr. Webster's claims with prejudice to refiling. On March 26,
1996, Mr. Webster appealed the final judgment to the Dallas, Texas Court of
Appeals. On April 10, 1998, the Texas Court of Appeals affirmed the trial
court's summary judgment ruling in favor of the defendants on each of Mr.
Webster's claims.


     Whitehall is also involved in certain legal proceedings in the normal
course of its business. After consultation with counsel, management is of the
opinion that the outcome of the above-mentioned proceedings will not have a

                      WHITEHALL'S MANAGEMENT'S DISCUSSION


OPERATING RESULTS


     Consolidated sales for the three months ended March 31, 1998 of $19.8
million, represented a 45.9% increase from the sales reported in the comparable
period of 1997. Sales for the first quarter of 1997 include $1.0 million
related to the Electronics segment which was sold in the first quarter of 1997.
Sales in the Aircraft Maintenance segment during the three months ended March
31, 1998 of $19.8 million were higher than aircraft maintenance sales during
the comparable periods in 1997. The increase was primarily due to (i) the
current quarter's use of hangar space that was unused in the corresponding
quarter of 1997 in anticipation of the U.S. Air Force C-130 maintenance
contract awarded during April of 1997 (subsequently canceled at the convenience
of the government in June of 1997) and (ii) sales from the Macon, Georgia
facility which was acquired in July of 1997.


     Consolidated sales totaled $65,791,000 for 1997, a decrease of 6% from
sales of $70,170,000 in 1996. Consolidated sales in 1996 include approximately
$1.9 million of sales in the Ocean Systems segment, which was sold in November
1996. Sales in the Electronics segment decreased by $2,212,000 to $672,000 in
1997. In March of 1997, Whitehall sold the Electronics segment for $2.7
million, see Item 1B and Note L of the Notes to Consolidated Financial
Statements. Aircraft Maintenance segment sales decreased by $221,000 to
$65,119,000 in 1997, primarily as a result of hangar space that was reserved in
anticipation of the United States Air Force C-130 maintenance contract awarded
in April 1997, which was subsequently canceled at the convenience of the
government in June 1997. The C-130 contract provides for reimbursement by the
United States Air Force of costs incurred during its operation, and Whitehall
has recorded a claim against the government for these costs. This reduction in
anticipated revenue was partially offset by the acquisition of the Macon,
Georgia facility, which accounted for approximately $12 million of the
segment's sales. Sales are also affected by arrivals of planes later than their
scheduled time.


     Consolidated sales totaled $70,170,000 for 1996, an increase of 25% over
sales of $56,229,000 in 1995. Aircraft Maintenance segment sales increased by
$22,699,000 to $65,340,000 in 1996, primarily as a result of its continued
expansion into the third party commercial aircraft maintenance market. Sales in
the Ocean Systems segment decreased by $8,002,000 to $1,946,000 in 1996.
Revenues in the Ocean Systems segment decreased primarily as a result of
contract completions with no follow-on contract awards. In November 1996,
Whitehall sold substantially all of the assets of the Ocean Systems segment,
see Item 1B and Note D of Whitehall's Consolidated Financial Statements--Years
Ended December 31, 1997, 1996 and 1995. Sales in the Electronics segment
decreased by $756,000 to $2,884,000 in 1996.


     Consolidated sales totaled $56,229,000 for 1995, an increase of 75% over
sales of $32,098,000 in 1994. Aircraft Maintenance segment sales increased by
$17,238,000 to $42,641,000 in 1995, primarily as a result of its continued
expansion into the third party commercial aircraft maintenance market. Sales in
the Ocean Systems segment increased by $6,126,000 to $9,948,000 in 1995.
Revenues in the Ocean Systems segment increased primarily as a result of new
product sales in the commercial geophysical market. Sales in the Electronics
segment increased by $767,000 to $3,640,000 in 1995.


     Gross profit on sales (derived by deducting cost of sales from sales)
during the first quarter of 1998 of $678,000, was lower than the $2.56 million
earned during the comparable 1997 period in the previous year. The decline was
primarily attributable to the capitalizing of certain cost of sales overhead
costs relating to the C-130 contract awarded during 1997.These capitalized
costs were subsequently expensed in the third and fourth quarter of 1997 upon
cancellation of the C-130 contract at the convenience of the government in June
of 1997.


     The first quarter of 1998 other income(net) of $249,000 as compared to
Whitehall's other income of $830,000 during the comparable period in 1997 is
primarily attributable to increased interest expense during the first quarter
of 1998 as compared to the first quarter of 1997.


     Whitehall's net loss during the three month period ended March 31, 1998 of
$4,000 is primarily attributable to the decreased gross profit described above.
 


                                       58

     Whitehall recorded an operating loss of $9,996,000 in 1997 compared to an
operating profit of $5,705,000 in 1996. The Aircraft Maintenance segment
reported an operating loss of $9,764,000 in 1997 compared to an operating
profit of $7,026,000 in 1996 primarily due to the increase in environmental
reserves (see "Environmental Matters" above), an increase in the provision for
obsolete inventory, and an increase in the allowance for doubtful accounts. The
allowance was increased because of disputes with large customers (the ultimate
outcome of which can not be determined at this time) and certain customers in
weak financial condition, including two customers that went into bankruptcy.
The Electronics segment reported an operating loss of $6,000 in 1997 compared
to an operating profit of $557,000 in 1996. The Electronics segment was sold in
March 1997. Corporate office general and administrative expenses decreased to
$337,000 in 1997 compared to $968,000 in 1996. This decline was the result of
lower insurance and legal expense reserves, as well as a reduction in corporate
staff and staff expenses.


     Whitehall recorded an operating profit of $5,705,000 in 1996 compared to
an operating profit of $2,875,000 in 1995. The Aircraft Maintenance segment
reported an operating profit of $7,026,000 in 1996 compared to an operating
profit of $3,430,000 in 1995. The improved profitability in the Aircraft
Maintenance segment resulted primarily from the increase in sales. Whitehall
increased its sales to its three largest customers in 1996 over those same
customers in 1995, mainly because those customers had increased the size of
their fleets. The Ocean Systems segment reported an operating loss of $789,000
in 1996 compared to an operating profit of $419,000 in 1995. The decline in
sales was the primary reason for the 1996 operating loss in the Ocean Systems
segment. The Electronics segment reported an operating profit of $557,000 in
1996 compared to an operating profit of $796,000 in 1995. The decline in sales
was the primary reason for the lower 1996 operating profit in the Electronics
segment. Corporate office general and administrative expenses decreased to
$968,000 in 1996 compared to $2,128,000 in 1995 primarily as a result of
reductions in legal and insurance expenses.


     Other expense, net in 1997 includes the $4,500,000 writedown of
Whitehall's investment in Hydroscience Technologies, Inc. (HTI) preferred stock
(See Item 1B). Other income in 1996 includes interest earned of $307,000 and
investment income of $440,000. Other income in 1995 includes gains on sales of
fixed assets of $650,000 and interest earned of $671,000. Other income in 1994
includes gains on sales of fixed assets of $512,000 and interest earned of
$791,000.


     Whitehall recorded an income tax benefit of $3,610,000 in 1997. Whitehall
recorded net income tax expense of $2,206,000 for 1996 and $889,000 in 1995.


YEAR 2000 ISSUE


     The Year 2000 issue is the result of computer programs being written using
two digits rather than four digits to define the applicable year. Any of
Whitehall's computer programs that have date-sensitive software may recognize a
date using '00' as the year 1900 rather than the year 2000. If Whitehall's
systems are unable to recognize or properly treat the year 2000, critical
financial and operational information may be processed incorrectly. Whitehall
has not yet assessed the year 2000 compliance expense and related potential
effect on Whitehall's earnings.


LIQUIDITY AND CAPITAL RESOURCES


     During the three months ended March 31, 1998, cash used in operations
totaled $1.59 million as compared to cash used in operations of $2.62 million
in the same period of 1997. The cash used in operations was primarily a result
of increases in trade accounts receivable and decreases in accounts payable and
other accrued liabilities. Whitehall's capital expenditures totaled $338,000
during the first three months of 1998 compared to $1.08 million during the same
period of 1997. The capital expenditures are a part of the continuing program
to maintain Whitehall's aircraft maintenance facilities.


     During 1997, cash used in operating activities totaled $4,545,000 as
compared to $4,084,000 in 1996 and $1,802,000 in 1995. Whitehall made capital
expenditures during 1997 of approximately $3,739,000


                                       59
<PAGE>

compared to $4,438,000, and $1,668,000 in 1996 and 1995. The majority of the
capital expenditures in all years were made to renovate the Aero facility in
Lake City, Florida. All planned major expansions have been completed as of
December 31, 1997. Including in 1997 capital expenditures was the construction
of a building and the purchase of other items for the C-130 contract and the
completion of the refinishing of various hanger floors. However, Whitehall will
make capital and other expenditures during 1998 as conditions warrant.


     Cash and cash equivalents decreased from approximately $2,656,000 at
December 31, 1996, to $1,251,000 at December 31, 1997. During 1997, Whitehall
borrowed an additional $7,163,000 on its line of credit primarily to fund
working capital, the acquisition of the Macon, Georgia facility, and capital
expenditures of $3,739,000. At December 31, 1997, there was approximately
$2,287,000 available under the line of credit.


     Whitehall believes that, despite the losses generated in 1997 mainly
attributable to the increase in the accounts receivable reserve, the increase
in the environmental reserve, and the writedown of its investment in the HTI
Preferred Stock, its cash balances and line of credit facility are sufficient
to meet its short and long-term capital requirements. Whitehall intends to
continue to pursue opportunities for the acquisition of aircraft maintenance
facilities, and any future acquisitions may require additional capital. In
order to provide additional funds for Whitehall's growth strategies and for
operations over the long-term, Whitehall may incur, from time to time,
additional short and long-term bank indebtedness and may issue, in public or
private transactions, equity and debt securities. The availability and terms of
such securities may depend upon market and other conditions. There can be no
assurances that such potential financing will be available on terms acceptable
to Whitehall.

                          COMPARATIVE PER SHARE DATA


     The following table sets forth certain historical per share data of AVS
and Whitehall and combined per share data on an unaudited pro forma basis,
based on the assumption that the merger occurred at the beginning of the
earliest period presented and was accounted for as a pooling of interests. The
pro forma comparative per share data gives effect to the merger at the exchange
ratio of .5143. The pro forma comparative per share data does not purport to
represent what AVS's financial position or results of operations would actually
have been had the merger occurred at the beginning of the beginning of the
earliest period presented or to project AVS's financial position or results of
operations for any future date or period. This data should be read in
conjunction with the unaudited pro forma condensed combined financial
statements and the separate historical financial statements and notes thereto
of AVS and Whitehall which are included elsewhere in this proxy statement.

(A) The 1995 and 1996 earnings per share for AVS include pro forma adjustments
    to record income taxes, as AVS conducted its business as a partnership
    prior to June 26, 1996.
(B) The 1995 and 1996 AVS per share data assumes that the 4,425,000 common
    shares issued to the partners and the 575,000 shares of common stock, the
    net proceeds in respect of which were paid to J/T Aviation Partners, were
    outstanding for periods prior to the closing of AVS's initial public
    offering in July 1996.
(C) The Whitehall per share data has been adjusted to give retroactive effect
    to the two-for-one stock split of Whitehall Common Stock, in the form of a
    100% stock dividend on April 15, 1997 to the stockholders of record at the
    close of business on March 25, 1997.
(D) This calculation assumes the issuance of approximately 2,844,079 shares of
    AVS common stock in the Merger, which is calculated based on an exchange
    ratio of .5143 shares of AVS common stock for each share of Whitehall
    common stock outstanding at March 31, 1998. Pro forma book value per share
    was computed by adding the 2,844,079 shares of AVS common stock to be
    issued in the Merger to the actual number of shares of AVS common stock
    outstanding at March 31, 1998.
(E) This calculation assumes the conversion of Whitehall's weighted average
    number of shares into the weighted average number of shares of AVS common
    stock, using an exchange ratio of .5143, for each respective period.
(F) This calculation assumes the conversion of Whitehall's shares of common
    stock outstanding at March 31, 1998 into shares of AVS common stock, using
    an exchange ratio of .5143.
(G) This calculation assumes the conversion of Whitehall's weighted average
    number of shares into the weighted average number of shares of AVS common
    stock, using an exchange ratio of .5143, for each respective period, added
    to the actual weighted average number of shares of AVS common stock.

       (   ) times by written consent in lieu of a meeting during the fiscal
year ended December 31, 1997. Each of the directors attended at least 75% of
the aggregate number of meetings of the AVS Board [and 75% of the total
meetings held by all committees of the AVS Board on which he served].

each director who is not an employee of AVS receives $1,000 for each meeting of
the AVS Board attended and $1,000 for each committee meeting attended.

exercise price equal to the initial public offering price. Additionally,
directors appointed to the AVS Board in the future will be granted options to

EMPLOYMENT AGREEMENTS


     Effective December 2, 1994, AVS entered into an employment agreement with
Mr. Baker. The employment agreement provides for an annual base salary of
$237,500 (to be increased annually by a cost of living adjustment). In
addition, AVS agreed to provide Mr. Baker with all employee benefits

     The employment agreements between AVS and Messrs. Baker and Woody each

     Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code") generally disallows an income tax deduction to public companies for
compensation over $1.0 million paid in a year to any one of the chief executive
officer or the four most highly compensated other executive officers, to the
extent that this compensation is not "performance based" within the meaning of
Section 162(m). As a result of this limitation, there can be no assurance that
all of the compensation paid to AVS's executive officers in the future will be
deductible.


STOCK OPTIONS


     The AVS Board and stockholders have adopted two stock option plans (the
"Plans"). Pursuant to the 1996 Director Stock Option Plan (the "Director
Plan"), options to acquire a maximum of the greater of 150,000 shares or 2% of
the number of shares of AVS Common Stock then outstanding may be granted to
directors of AVS. Pursuant to the 1996 Stock Option Plan, options to acquire a
maximum of the greater of 650,000 shares common stock or 8% of the number of
shares of common stock then outstanding may be granted to executive officers,
employees (including employees who are directors), independent contractors and
consultants of AVS. Options to purchase 386,057 shares at exercise prices
ranging from $19.00 per share to $25.25 per share are currently outstanding
under the Plans, 254,800 of which are immediately exercisable.


     The Plans are administered by the Compensation Committee of the AVS Board
which was formed in January 1997. Prior to the formation of the Compensation
Committee, the AVS Board administered the Plans. The Compensation Committee
determines which persons will receive options and the number of options to be
granted to such persons. The Director Plan also provides for annual mandatory
grants of options to directors. See "Compensation of Directors." The
Compensation Committee will also interpret the provisions of the Plans and make
all other determinations that it may deem necessary or advisable for the
administration of the Plans.


     Pursuant to the Plans, AVS may grant Incentive Stock Options ("ISOs") as
defined in Section 422(b) of the Code, and Non-Qualified Stock Options
("NQSOs"), not intended to qualify under Section 422(b) of the Code. The price
at which AVS's Common Stock may be purchased upon the exercise of options
granted under the Plans will be required to be at least equal to the per share
fair market value of the common stock on the date the particular options are
granted. Options granted under the Plans may have maximum terms of not more
than ten years and are not transferable, except by will or the laws of descent
and distribution. None of the ISOs under the Plans may be granted to an
individual owning more than 10% of the total combined voting power of all
classes of stock issued by AVS unless the purchase price of the common stock
under such option is at least 110% of the fair market value of the shares
issuable on exercise of the option determined as of the date the option is
granted, and such option is not exercisable more than five years after the
grant date.


     Generally, options granted under the Plans may remain outstanding and may
be exercised at any time up to three months after the person to whom such
options were granted is no longer employed or retained by AVS or serving on the
AVS Board .


     Pursuant to the Plans, unless otherwise determined by the Compensation
Committee, one-third of the options granted to an individual are exercisable
upon grant, one-third are exercisable on the first anniversary of such grant
and the final one-third are exercisable on the second anniversary of such
grant. However, options granted under the Plans shall become immediately
exercisable if the holder of such options is terminated by AVS or is no longer
a director of AVS, as the case may be, subsequent to certain events which are
deemed to be a "change in control" of AVS. A "change in control" of AVS
generally is deemed to occur when (a) any person becomes the beneficial owner
of or acquires voting control with respect to more than 20% of the common stock
(or 35% if such person was a holder of common stock on July 2, 1996, the date
of AVS's initial public offering); (b) a change occurs in the composition of a
majority of AVS's Board during a two-year period, provided that a change with
respect to a member of the AVS Board shall be deemed not to have occurred if
the appointment of a member of AVS's Board is approved by a vote of at least
75% of the individuals who constitute the then existing AVS Board ; or (c)
AVS's stockholders approve the sale of all or substantially all of AVS's
assets.


                                       70
<PAGE>

     ISOs granted under the Plans are subject to the restriction that the
aggregate fair market value (determined as of the date of grant) of options
which first become exercisable in any calendar year cannot exceed $100,000.


     The Plans provide for appropriate adjustments in the number and type of
shares covered by the Plans and options granted thereunder in the event of any
reorganization, merger, recapitalization or certain other transactions
involving AVS.


PERFORMANCE GRAPH


     The following graph compares the total return on AVS Common Stock with the
cumulative total return on the Standard & Poor's ("S&P") 500 Index, the S&P
Midcap 400 Index, the S&P SmallCap 800 Index, the Dow Jones Equity Market Index
and a peer group index selected by AVS, for the period between AVS's initial
public offering on June 27, 1996 and December 31, 1997.


     The peer group selected by AVS is comprised of the following companies:
AAR Corp., Aviall, Inc., Banner Aerospace, Inc., Greenwich Air Services, Inc.,
UNC, Inc. and Kellstrom.


     These indices relate only to stock prices; they do not purport to afford
direct comparison of the business or financial performance of the companies
comprising such indices with AVS nor with each other.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION


     The Compensation Committee is responsible for making recommendations to
the AVS Board concerning executive compensation, including base salaries,
bonuses and the bases for their award, stock option plans and other benefits.
Each of the members of the Compensation Committee is an independent outside
director of AVS. The Compensation Committee was formed in January 1997.


     To date, the compensation for AVS's senior executive officers has been
largely governed by their employment agreements with AVS. These employment
agreements were entered into prior to the formation of the Compensation
Committee. As a result, the Compensation Committee has not had a significant
role in determining executive compensation.


     The Compensation Committee believes that in the future, in determining
compensation for AVS's senior executive officers, the Compensation Committee
will generally consider the overall performance of AVS during the prior fiscal
year, the individual executive officer's contribution to the achieving of
operating goals and business objectives and levels of compensation of companies
similar in size and development to AVS.


     It is the Compensation Committee's view that senior executives' interests
should complement those of stockholders. Accordingly, a substantial portion of
senior executive compensation above a base salary should be provided through
bonuses tied to certain indicators of the performance of AVS and through the
grant of stock options, thus creating incentives for executives to achieve
long-term AVS objectives and increase stockholder value.


                      BY THE MEMBERS OF THE COMPENSATION COMMITTEE
                                 ROBERT ALPERT
                                 SAM HUMPHREYS


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION


     In January 1997, the AVS Board organized a Compensation Committee
comprised of Robert Alpert, Sam Humphreys and Tim L. Watkins. During the past
fiscal year, none of AVS's directors or executive officers (i) served as a
member of the compensation committee or similar committee of another entity,
one of whose executive officers served on the AVS Board or the AVS Compensation
Committee; or (ii) served as a director of another entity, one of whose
executive officers served on the AVS Board or the AVS Compensation Committee.


COMPLIANCE WITH SECTION 16(A)


     Based solely upon a review of Forms 3 and 4 and amendments thereto
furnished to AVS pursuant to Rule 16a-3(d) under the Exchange Act, during AVS's
fiscal year ended December 31, 1997 and any Forms 5 and amendments thereto
furnished to AVS with respect to its most recent fiscal year, and any


                                       72

written representations referred to in subparagraph (b)(2)(i) of Item 405 of
Regulation S-K, except as set forth below, no person who at any time during the
fiscal year ended December 31, 1997 was a director, officer or, to the
knowledge of AVS, a beneficial owner of more than 10% of any class of equity
securities of AVS registered pursuant to Section 12 of the Exchange Act failed
to file on a timely basis, as disclosed in Forms 3, 4 and 5, reports required
by Section 16(a) of the Exchange Act during the fiscal year ended December 31,
1997. AVS has been advised that each of Dale S. Baker, Harold S. Woody, Michael
A. Saso and James D. Innella have not filed a Form 4 that was due, that Joseph
E. Civiletto has not filed an amendment to a Form 5 that was due and that
William H. Alderman has not filed a Form 5 that was due. AVS has been advised
that each of the foregoing persons intends to make such filings in the
immediate future.




             AVS'S CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


     As of December 2, 1994, AVS entered into a 20-year lease with Aviation
Properties, a Delaware general partnership ("Aviation Properties"), pursuant to
which AVS leases its corporate headquarters and warehouse in Miami, Florida
(the "Miami Property"). AVS makes annual payments under such lease in the
amount of approximately $892,990. The sole partners of Aviation Properties are
(a) AVAC Corporation ("AVAC") and (b) J/T Aviation Partners, a Delaware general
partnership ("J/T"). The sole stockholder and president of AVAC is Robert
Alpert, a principal stockholder and director of AVS. J/T was also a principal
stockholder of AVS through December 1997.


     In connection with Aviation Properties' purchase of the Miami Property,
AVS and Aviation Properties entered into a loan agreement (the "Loan
Agreement") whereby AVS made a $2.5 million loan to Aviation Properties, which
loan bears interest at 8.0% per annum, with principal and interest due in a
single payment on December 2, 2004.


     As of December 2, 1994, AVS entered into a six-year lease with Aviation
Properties of Texas, a Delaware general partnership ("AVTEX"), pursuant to
which AVS leases a warehouse in Pearland, Texas (the "Pearland Property").
Until it acquired the Pearland Property through a wholly-owned subsidiary, AVS
made annual payments under such lease in the amount of $114,468. The sole
partners of AVTEX are AVAC and J/T.


     In March, 1998, Aviation Sales Operating Company ("ASOC"), a wholly-owned
subsidiary of AVS, acquired the Pearland Property from AVTEX in exchange for
(i) ASOC's cancellation of all outstanding principal balance and unpaid accrued
interest on a promissory note of AVTEX held by ASOC in the principal amount of
$434,244 and (ii) ASOC's assumption of indebtedness in the principal amount of
$1,128,855 which was secured by a deed of trust in favor of a third party.


     AVS believes the terms of the Loan Agreement, the terms of the leases with
Aviation Properties and AVTEX and the then terms of the purchase of the
Pearland Property are no less favorable than could be obtained from an
unaffiliated third party.


     At January 1, 1995, Messrs. Baker, Woody, Saso, Civiletto and Innella were
granted options (the "Options") by the partners of ASC Acquisition Partners, LP
d/b/a Aviation Sales Company (the "Partnership") (AVAC and J/T) to purchase an
aggregate of 13.5% of the outstanding limited partnership interests in the
Partnership for an exercise price greater than the fair market value of the
interests in the Partnership at that date. At January 1, 1996, the Options were
exercised in full by delivery to AVAC and J/T of full recourse promissory notes
(the "Promissory Notes") in the aggregate principal amounts set forth below,
representing the payment in full of the exercise price of the Options:

</TABLE>

     Management's interests in the Partnership were subject to a first priority
pledge to the lenders under AVS's revolving credit facility and a second
priority pledge to AVAC and J/T to secure the repayment of their respective
Promissory Notes. The Promissory Notes bear interest at the rate of 8.0% per
annum, with principal and interest due and payable on the earlier of January 1,
2001 or from the net proceeds available upon the sale of any portion of the
collateral securing the Promissory Notes. Immediately prior to AVS's initial
public offering in June 1996, management contributed their interests in the
Partnership to AVS in exchange for shares of Common Stock. At such time,
management pledged their shares of AVS Common Stock to secure the repayment of
their respective Promissory Notes. The exercise price of the Options after
giving effect to the exchange of Partnership interests for shares of common
stock would effectively have been $2.13 per share. In April 1998, Mr. Saso paid
in full the amounts outstanding under his Promissory Notes to AVAC and J/T.


     AVS was obligated to pay a fee of $50,000 per quarter to an entity
controlled by Mr. Alpert for consulting services. AVS's obligation to pay this
fee expired in February 1997.


     On December 31, 1997, AVS issued 3,000 unregistered shares of AVS Common
Stock in consideration for past services to each of Messrs. Baker, Woody,
Innella, Saso, Civiletto and Alderman. The fair value of these shares on the
date of issuance was $677,250 in the aggregate or $112,875 per person.

                                PROPOSAL NO. 2
                             ELECTION OF DIRECTORS


     At the Meeting, two directors will be elected to serve on the AVS Board.
The two directors will be elected to serve until the 2001 Annual Meeting of
Stockholders (or until their successors are elected and qualified).


     It is intended that proxies will be voted for the following nominees for a
three year term ending at the 2001 Annual Meeting of Stockholders: Robert
Alpert and       . Brief biographies of each of the nominees for director are
set forth under "Board of Directors" above.


     The affirmative vote of stockholders holding a majority of the issued and
outstanding AVS Common Stock in attendance at the meeting, either in person or
by proxy, is required to approve this proposal.


     THE AVS BOARD RECOMMENDS A VOTE IN FAVOR OF THOSE PERSONS NOMINATED FOR
ELECTION TO THE BOARD OF DIRECTORS.



                                PROPOSAL NO. 3
                           RATIFICATION OF AUDITORS


     The AVS Board has approved the engagement of the firm of Arthur Andersen
LLP as AVS's independent auditors. Arthur Andersen LLP has served as AVS's
independent auditors since 1992, and is familiar with AVS's business and
management. The AVS Board believes that Arthur Andersen LLP has the personnel,
professional qualifications and independence necessary to act as AVS's
independent auditors.


     Representatives of Arthur Andersen LLP are expected to appear at the
Meeting to make a statement, if they wish to do so, and to be available to
answer appropriate questions from stockholders at that time.


     Although stockholder approval of AVS's auditors is not required, the AVS
Board is submitting such appointment to a vote of AVS's stockholders. Approval
of this proposal will require the affirmative vote of a majority of the issued
and outstanding AVS Common Stock in attendance at the meeting, voting in person
or by proxy. In the event this proposal is not approved, management will
reconsider its selection of Arthur Andersen LLP as independent auditors.


     THE AVS BOARD RECOMMENDS A VOTE IN FAVOR OF THIS PROPOSAL.

     The AVS Board is not aware of any other business that may come before the
meeting. However, if additional matters properly come before the meeting,
proxies will be voted at the discretion of the proxy-holders.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


To the Board of Directors and Stockholders of
Aviation Sales Company:


     We have audited the accompanying consolidated balance sheets of Aviation
Sales Company (a Delaware corporation) and subsidiaries as of December 31, 1997
and 1996, and the related consolidated statements of income, partners' capital
and stockholders' equity and cash flows for each of the three years in the
period ended December 31, 1997. These financial statements and the schedule
referred to below are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.


     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Aviation Sales Company and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.


     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index to
financial statements is presented for purposes of complying with the Securities

NOTE 1--GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


ORGANIZATION AND OPERATIONS


     Aviation Sales Company ("ASC" or the "Company") is a Delaware corporation.
The operations of the Company were initially conducted by AJT Capital Partners
d/b/a Aerospace International Services ("AIS"). AIS was formed in February 1992
to acquire certain aircraft spare parts owned by Eastern Air Lines, Inc. (the
"EAL Inventory") and certain outstanding accounts receivable. On December 2,
1994, (effective November 30, 1994) AIS organized ASC Acquisition Partners,
L.P. (the "Partnership") to acquire the Aviation Sales Company business unit
from Aviall Services, Inc. ("Aviall") and to operate the business of AIS and
the Partnership on a going forward basis. Simultaneously with the acquisition,
AIS contributed all of its assets to the Partnership. For accounting purposes,
the Partnership and AIS were considered related parties as the ultimate
ownership interests of the Partnership were held by parties who owned
substantially the same ownership percentage in AIS. As a result, the
combination was accounted for in a manner similar to a pooling of interests.


     The Company was formed on June 26, 1996, when: (i) all but one of the
parties holding interests in the Partnership contributed their interests in the
Partnership to the Company in exchange for 2,924,000 shares of the Company's
common stock, and (ii) one of the parties holding an interest in the
Partnership, J/T Aviation Partners ("J/T"), contributed its interest in the
Partnership to the Company in exchange for 1,501,000 shares of the Company's
common stock and an amount equal to the proceeds to be received by the Company
for 575,000 shares of common stock sold in the offering, as more completely
described below.


     On June 26, 1996, the Company's registration statement on Form S-1 was
declared effective. On July 2, 1996, the Company closed its public offering of
3,250,000 shares of its common stock at $19 per share. In addition, the Company
granted the underwriters of its public offering a 30-day option to purchase up
to 487,500 additional shares of its common stock to cover the over-allotment
option. On July 25, 1996, the underwriters exercised the over-allotment option
and the Company sold an additional 487,500 shares of its common stock.


     The net proceeds from the offering after all expenses were $64,576,607. Of
such proceeds, $10,160,250 was used to pay indebtedness due to J/T in
connection with the formation of the Company. The remaining proceeds were used
to repay senior and subordinated indebtedness. See Note 5.


ACCOUNTING ESTIMATES


     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.


PRINCIPLES OF CONSOLIDATION


     The accompanying consolidated financial statements include the accounts of
ASC and its wholly owned subsidiaries. All significant intercompany
transactions and balances have been eliminated.

NOTE 1--GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

CASH AND CASH EQUIVALENTS


     The Company considers all deposits with an original maturity of three
months or less to be cash equivalents. Cash and cash equivalents at December
31, 1996 and 1997, include cash held by the Company in demand deposit accounts.
 


REVENUE RECOGNITION


     Sales of aircraft parts are recognized as revenues when the product is
shipped and title has passed to the customer. The Company records reserves for
estimated sales returns in the period sales are made. Reserves for returns as
of December 31, 1996 and 1997 were $1,227,598 and $1,740,813, respectively. The
Company also warehouses and sells inventories on behalf of others under
consignment arrangements. The Company records commission revenues on the sale
of consignment inventories upon shipment of the product. The Company exchanges
rotable parts in need of service or overhaul for new, overhauled or serviceable
parts in its inventory for a fee. Fees on exchanges are recorded in revenue at
the time the product is shipped. The Company performs inventory repair
management and warehouse management services to customers on a contractual
basis. These service fees are recorded in revenue over the course of the
contract as the services are rendered. Gain on sale of equipment on lease is
included in rentals from leases and other.


INVENTORIES


     Inventories, which consist primarily of aviation parts, are stated at the
lower of cost or market on primarily a specific identification basis. In
instances where bulk purchases of inventory items are made, cost is determined
based upon an allocation by management of the bulk purchase price to the
individual components. Expenditures required for the recertification of parts
are capitalized as inventory and are expensed as the parts associated with the
re-certification are sold. The Company enters into consignment arrangements for
bulk quantities of inventory items. Costs to disassemble and warehouse bulk
items are capitalized and expensed as the consigned items are sold. As a result
of the acquisitions of Aerocell and Kratz in 1997, the Company maintains raw
materials and work in progress inventories in support of those manufacturing
and overhaul facilities. At December 31, 1996 and 1997, inventories consisted
of the following:

EQUIPMENT ON LEASE


     The Company, primarily through Aviation Sales Leasing Company, leases
engines and spare parts inventories to the airline industry on a worldwide
basis through operating leases. Operating lease income is recognized on a
straight-line basis over the term of the underlying leases. The cost of
equipment on lease is amortized, principally on a straight-line basis, to the
estimated remaining net realizable value over the lease term or the economic
life of the equipment.

                                             ============      ============
</TABLE>

     For financial reporting purposes, the Company provides for depreciation of
property and equipment using the straight-line method at annual rates
sufficient to amortize the cost of the assets less estimated salvage values
over their estimated useful lives. Estimated useful lives range from 3 to 15
years for the Company's property and equipment.


     Maintenance and repair expenditures are charged to expense as incurred,
and expenditures for betterments and major renewals are capitalized. The
carrying amounts of assets which are sold or retired and the related
accumulated depreciation are removed from the accounts in the year of disposal,
and any resulting gain or loss is reflected in income. Such gains or losses
were not significant during the years ended December 31, 1995, 1996 and 1997.


     Depreciation expense amounted to $510,455, $746,626 and $1,777,559 for the
years ended December 31, 1995, 1996 and 1997, respectively.



INTANGIBLE ASSETS


     The costs associated with obtaining financing are included in the
accompanying consolidated balance sheets as deferred financing costs and are
being amortized over the initial terms of the loans to which such costs relate.
Amortization expense for the years ended December 31, 1995, 1996 and 1997 was
$666,607, $616,183 and $385,582, respectively. During the first quarter of
1998, the Company completed the offering and sale of $165 million in senior
subordinated notes, using a portion of the proceeds to retire existing debt. In
connection with these transactions, the Company will write off the deferred
financing costs related to the term loan agreements eliminated with the
proceeds. See Note 14.


     The excess of the purchase price over the fair values of the net assets
acquired from Kratz-Wilde Machine Company, Inc. in 1997 was approximately $17.9
million. This amount has been recorded as goodwill, which is being amortized on
a straight-line basis over 20 years. Amortization expense for the year ended
December 31, 1997 was $189,602.

     The Company continually evaluates whether events and circumstances have
occurred that may warrant revision of the estimated useful life of intangible
assets or whether the remaining balance of intangible assets should be
evaluated for possible impairment. The Company uses an estimate of the related
undiscounted cash flows over the remaining life of the intangible assets in
measuring their recoverability.


DEFERRED INCOME

     Advance payments and deposits received on operating leases are initially
deferred and subsequently recognized as the Company's obligations under the
lease agreement are fulfilled.


STOCK COMPENSATION PLANS

     At December 31, 1997, the Company has two stock-based compensation plans,
which are more fully described in Note 12. The Company accounts for the fair
value of its grants under those plans in accordance with Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25").
The Company adopted Statement of Financial Accounting Standards No.  123,
"Accounting for Stock-Based Compensation" ("SFAS 123") on January 1, 1996.


INCOME TAXES

     Prior to June 26, 1996, the business of the Company was conducted by the
Partnership and therefore was not subject to income taxes. The Company, as a
result of the transfer of the net assets of the Partnership to the Company and
the initial public offering of its common stock, became subject to federal and
state income taxes. At that time, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109").
Deferred income taxes, which arose primarily as a result of temporary
differences between the Partnership's book and tax basis of certain assets and
liabilities, were recorded, resulting in an adjustment to the Company's
reported earnings in the period of adoption. A deferred income tax benefit of
$914,459 was credited to operations at the time of adoption. The transfer of
J/T's interest in the Partnership to the Company described in Note 1 resulted
in a step-up in basis in the Company's net assets for tax purposes. As a
result, during 1996, a deferred tax benefit of $3,962,498 was recorded. See
Note 11.

     Under SFAS 109, deferred tax assets or liabilities are computed based upon
the difference between the financial statement and income tax basis of assets
and liabilities using the enacted marginal tax rate

                                      F-12

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)


NOTE 1--GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

applicable when the related asset or liability is expected to be realized or
settled. Deferred income tax expenses or benefits are based on the changes in
the asset or liability from period to period. If available evidence suggests
that it is more likely than not that some portion or all of the deferred tax
assets will not be realized, a valuation allowance is required to reduce the
deferred tax assets to the amount that is more likely than not to be realized.
Future changes in such valuation allowance would be included in the provision
for deferred income taxes in the period of change.


FINANCIAL INSTRUMENTS


     The carrying amounts of cash and cash equivalents, accounts receivable and
accounts payable approximate fair value due to the short maturity of the
instruments and the provision for what management believes to be adequate
reserves for potential losses. Management believes the fair value of long-term
debt approximates the carrying amount of long-term debt in the accompanying
consolidated balance sheets as substantially all of the Company's long-term
debt reprices to market based on variable interest rate terms.


YEAR 2000 SYSTEMS COSTS


     The Company utilizes software and related technologies throughout its
businesses that will be affected by the date change in the year 2000. The
Company is currently in the early stages of purchasing and implementing a new
management information system which management believes will mitigate the Year
2000 issues currently inherent in the Company's existing systems. However, the
Company cannot measure the impact that the Year 2000 issue will have on its
vendors, suppliers, customers and other parties with which it conducts
business. The cost of the new MIS system is expected to be approximately $8.0
million, which will be incurred over approximately a two-year period.


RECENTLY ISSUED ACCOUNTING STANDARDS


     Statement of Financial Accounting Standards No. 128, "Earnings Per Share"
("SFAS 128"), is effective for fiscal years ending after December 15, 1997.
This statement specifies the computation, presentation and disclosure
requirements for earnings per share for entities with publicly held common
stock or potential common stock. Earnings per share have been restated to
comply with SFAS 128 for all periods presented. See Note 10.


     The Company adopted Statement of Financial Accounting Standards No.  121,
"Accounting for the Impairment of Long-lived Assets and for Long-lived Assets
to be Disposed Of" ("SFAS 121") in 1996. SFAS 121 establishes accounting
standards for recording the impairment of long-lived assets, certain
identifiable intangibles and goodwill. The adoption of SFAS 121 did not have a
material impact on the Company's financial position or results of its
operations.


     Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" ("SFAS 130"), was issued by the Financial Accounting
Standards Board in June 1997. This statement establishes standards for the
reporting and display of comprehensive income and its components in a full set
of financial statements. The objective of SFAS 130 is to report a measure
(comprehensive income) of all changes in equity of an enterprise that result
from transactions and other economic events in a period other than transactions
with owners. Management believes the adoption of SFAS 130

will not have a material impact on the Company's consolidated financial

NOTE 2--BUSINESS COMBINATIONS


ACQUISITIONS ACCOUNTED FOR UNDER THE PURCHASE METHOD OF ACCOUNTING:


     On August 9, 1996, the Company completed the acquisition of certain assets
of the business of Dixie Bearings, Incorporated ("Dixie") relating primarily to
the sale of new bearings for use in aircraft for a purchase price of
approximately $9.0 million. The acquisition was accounted for using the
purchase method of accounting. Accordingly, the operations of Dixie since the
acquisition have been included in the accompanying consolidated financial
statements from the date of acquisition. The historical operations of Dixie,
when compared to the historical operations of the Company, are not significant.
In connection with the acquisition, the Company borrowed $6,000,000 of senior
notes payable to financial institutions and paid the balance in cash. See Note
5.


     On October 17, 1997 the Company completed the acquisition of substantially
all of the assets of the business of Kratz-Wilde Machine Company, a Kentucky
corporation ("Kratz-Wilde") for a purchase price, including acquisition costs
and net cash acquired, of approximately $39.6 million in cash and notes and the
assumption of certain liabilities of Kratz-Wilde in the approximate amount of
$2.2 million. Kratz-Wilde specializes in the manufacture of machined components
primarily for jet engines, and also produces some automotive and faucet
components. The acquisition was accounted for using the purchase method of
accounting and accordingly, the purchase price has been allocated to the assets
purchased and the liabilities assumed based upon the fair values at the date of
acquisition. The operations of Kratz-Wilde since the acquisition have been
included in the accompanying consolidated financial statements from the date of
acquisition. As a result of the Kratz-Wilde acquisition, the Company's
operating revenues increased approximately $6.5 million from the date of the
acquisition through December 31, 1997. In connection with the acquisition, the
Company borrowed $40.0 million of senior notes payable to financial
institutions, with the remainder of the acquisition price payable to the prior
owners over a two year period. See Note 5.

Amended Credit Facility consisted of (a) a term loan facility in an original
principal amount of $20.0 million and (b) a $50.0 million revolving loan,
letter of credit and acquisition loan facility. In connection with the
repayment and restructuring of the previous bank lending agreement, the Company

$18.6 million, and (b) a $131.4 million revolving loan, letter of credit and
acquisition loan facility, subject to an availability calculation based on the
eligible borrowing base (the "Third Amended Revolving Credit Facility"). The
eligible borrowing base includes certain receivables and inventories of the
Company. The letter of credit portion of the Third Amended Revolving Credit
Facility is subject to a $15 million sublimit and the acquisition loan portion
of the Third Amended Revolving Credit Facility is subject to a $40 million
sublimit, with the imposition of certain borrowing criteria based on the
satisfaction of certain debt ratios. The interest rate on the Third Amended
Credit Agreement is, at the option of the Company, (a) prime plus a margin, or
(b) LIBOR plus a margin, where the margin determination is made based upon the
Company's financial performance over the 12 month period (ranging from 0.0% to
1.25% in the event prime is utilized, or 1.50% to 2.75% in the event LIBOR is
utilized). At December 31, 1997, the margin was .25% for prime rate loans and
1.75% for LIBOR rate loans.


     The Third Amended Term Loan, as well as any portion of the revolving
credit facility utilized to make acquisitions, amortizes in equal quarterly
installments and terminates on July 31, 2002. Interim payments under the Third
Amended Revolving Credit Facility will be made from daily collections of the
Company's accounts receivable. The Third Amended Revolving Credit Facility will
terminate on July 31, 2002. The Third Amended Credit Agreement contains
financial and other covenants and mandatory prepayment events, as defined. At
December 31, 1997, the Company was in compliance with all covenants of the
Third Amended Credit Agreement. The Third Amended Credit Agreement is secured
by a lien on substantially all of the assets of the Company. On December 31,
1997, the outstanding balances under the Third Amended Term Loan and Third
Amended Revolving Credit Facility were $55.6 million (including $38.0 million
borrowed under the acquisition subfacility) and $86.4 million, respectively.


     The Company entered into a subordinated loan agreement (the "Subordinated
Debt") on December 2, 1994, whereby the Partnership borrowed $7.0 million from
the partners which was payable in a single lump sum on the earlier of June 2,
2001, or six months after amounts borrowed pursuant to the credit facility have
been paid in full. Upon the earlier to occur of June 2, 2001 or the repayment
of the Subordinated Debt in full, the Company was required to pay to the
partners an additional facility fee of $350,000, provided that, if the
Subordinated Debt was prepaid in full prior to June 2, 1996, the Company would
be released from its obligation to pay such facility fee. On July 2, 1996, the
Company repaid the Subordinated Debt in full and the facility fee with a
portion of the proceeds of the initial public offering. The Subordinated Debt
bore interest at prime plus 5 percent.


     On August 5, 1997, the Company entered into a term loan agreement in a
principal amount of $7.2 million to finance certain equipment and rotable parts
on a long-term lease, which secure the loan. This loan is payable in 59
consecutive equal monthly payments of $91,750 commencing September 14, 1997,
with a final balloon payment due on August 14, 2002. Interest on this term loan
is fixed at 8.21%. The Company has leased the underlying equipment and rotable
parts to unrelated third parties. Interim payments under the term loan will be
made from the proceeds of these parts leases. This term loan contains financial
and other covenants and mandatory prepayment events, as defined. At December
31, 1997, the Company was in compliance with all covenants of this term loan.


     As described in Note 2, the Company borrowed $6.0 million on August 9,
1996, under the acquisition loan portion of the Amended Revolving Credit
Facility for the acquisition of certain assets of the business of Dixie. This
credit facility has since been amended, as described above.

NOTE 5--NOTES PAYABLE--(CONTINUED)

     In connection with the October 17, 1997 acquisition of Kratz-Wilde (See
Note 2), the company entered into an agreement with the prior owners to pay
$2.2 million of the acquisition price over a two year period. Payments of
$1,250,000 are due on January 1, 1999 and January 1, 2000. Interest on this
note has been imputed at 8%.


NOTE 6--RELATED-PARTY TRANSACTIONS


     The Company leases its corporate headquarters and warehouse in Miami,
Florida (the "Miami Property") and a warehouse in Pearland, Texas (the
"Pearland Property") from related parties. The lease on the Miami Property
calls for annual payments in the amount of $892,990 expiring on December 2,
2014. The Company is required to make annual payments under the Pearland
Property lease in the amount of $114,468. This lease expires December 2, 2000.
The Company believes the terms of these leases are no less favorable than could
be obtained from an unaffiliated third party. As described more thoroughly in
Note 14, the Company purchased the Pearland Property on March 13, 1998 for
approximately $1.8 million.


     In connection with the purchase of the Miami Property by the related
party, the Company made an unsecured $2,465,519 loan to the related party,
which bears interest at 8% per annum, with principal and interest due in a
single payment on December 2, 2004. The outstanding balance is included in
amounts due from related parties in the accompanying balance sheets. The
Company believes the terms of this loan are no less favorable than could be
obtained from an unaffiliated third party.


     At December 31, 1997, as payment of bonuses, six officers of the Company
were each granted 3,000 shares of the Company's common stock. The fair value of
these shares on the date of issuance, $677,250, has been included in general
and administrative expenses in the accompanying 1997 statement of operations.


NOTE 7--COMMITMENTS AND CONTINGENCIES


     The Company is currently involved in various lawsuits and other
contingencies arising out of operations in the normal course of business. In
the opinion of management, the ultimate resolution of those claims and lawsuits
will not have a material adverse effect on the financial position or results of
operations of the Company.


     The Company has certain employment agreements with officers and employees
dated December 1994, which extend from three to five years and are renewable in
one-year periods thereafter. The employment agreements provide that such
officers and employees may earn bonuses, based upon a sliding percentage scale
of their base salaries, provided the Company achieves certain financial
operating results, as defined. Further, each of the employment agreements
provides that in the event of (a) a change in control of the Company including
the vesting of decision-making authority in one of the Company's current
officers; (b) the sale of all or substantially all of the assets of the Company
to a third party for which the executive officer does not continue in
employment; or (c) the merger or consolidation of the Company with an entity
for which the executive officer does not continue in employment, the employment
agreement shall be terminable by the executive officer upon 90 days' notice and
one year's base salary shall be payable to the executive officer as a
termination fee.


     At January 1, 1995, five officers and employees of the Company were
granted options (the "Options") by the partners to purchase an aggregate of
13.5% of the outstanding limited partnership

interests in the Partnership for an aggregate exercise price of $1,437,027,
which was greater than the fair market value, as determined by an independent,
third party, of the interests in the Partnership at that date. At January 1,
1996, the Options were exercised in full by delivery to the partners of full
recourse promissory notes representing the payment in full of the exercise
price of the Options.


     On November 26, 1997, the Company settled an outstanding legal claim
against a former employee and shareholder of the Company. As part of this
settlement, the employee agreed to leave the Company and transfer 75,000 shares
of the Company's common stock back to the Company, which shares the Company
immediately retired. The fair value of the shares at the date of the
settlement, approximately $2.6 million, has been reflected as a reduction of
general and administrative expense in the accompanying 1997 statement of
operations.


     The Company has purchase commitments to various airlines whereby the
Company sells aircraft inventory as agent for such airlines. Pursuant to such
agreements, the Company has commitments to various airlines requiring the
Company to purchase a minimum amount of inventory from such airlines if minimum
sales targets are not met. In the opinion of management, the Company's
commitments will be realized through future sales of aircraft inventory owned
by such airlines.


     Effective January 1, 1995, the Company established a qualified defined
contribution plan (the "Plan") for eligible employees. The Plan provides that
employees may contribute up to the maximum percent of pretax earnings as
allowed by the U.S. tax code and the Company may elect, at its discretion, to
make contributions to the Plan in any year. The Company contributed
approximately $197,000, $309,000 and $296,000 to the Plan in 1995, 1996 and
1997, respectively. The Company does not provide retired employees any health
or life insurance benefits.


NOTE 8--LEASES


     The Company leases certain buildings and office equipment under operating
lease agreements. Two of the buildings are leased from related parties of the
Company (See Note 6). For the years ended December 31, 1995, 1996 and 1997,
rent expense under these leases amounted to $1,554,677, $1,813,113 and
$2,300,585, respectively. Minimum rental commitments under operating leases are

NOTE 10--EARNINGS PER SHARE


     The Company adopted Statement of Financial Accounting Standards No. 128
("SFAS 128"), "Earnings Per Share" during 1997. SFAS 128 establishes standards
for computing and presenting basic and diluted earnings per share. Basic
earnings per share is computed by dividing net income by the weighted average
common shares outstanding during the year. Diluted earnings per share is based
on the combined weighted average number of common shares and common share
equivalents outstanding which include, where appropriate, the assumed exercise
of options. In computing diluted earnings per share, the Company has utilized
the treasury stock method. All prior period earnings per share data have been
restated to conform with SFAS 128.


     The computation of weighted average common and common equivalent shares
used in the calculation of basic and diluted earnings per share is as follows:

     For business combinations accounted for as pooling of interests, earnings
per share computations are based on the aggregate of the weighted-average
outstanding shares of the constituent businesses, adjusted to equivalent shares
of the surviving business for all periods presented.


PRO FORMA EARNINGS PER SHARE


     Prior to June 26, 1996, the operations of the Company were conducted by
the Partnership, a Delaware general partnership and, therefore, the results of
operations for the year ended December 31, 1995 and for the period January 1,
1996 through June 26, 1996, do not include a provision for income taxes, as the
income of the Partnership passed directly to its partners.

NOTE 12--STOCK OPTION PLANS


     In connection with the organization of the Company, the Company adopted
two stock option plans (the "Plans"). Pursuant to the 1996 Director Stock
Option Plan (the "Director Plan"), options to acquire a maximum of the greater
of 150,000 shares or 2% of the number of shares of Common Stock then
outstanding may be granted to directors of the Company. Pursuant to the 1996
Stock Option Plan (the "1996 Plan"), options to acquire a maximum of the
greater of 650,000 shares of Common Stock or 8% of the number of shares of
Common Stock then outstanding may be granted to executive officers, employees
(including employees who are directors), independent contractors and
consultants of the Company. The price at which the Company's common stock may
be purchased upon the exercise of options granted under the Plans will be
required to be at least equal to the per share fair market value of the Common
Stock on the date the particular options are granted. Options granted under the
Plans may have maximum terms of not more than ten years. Generally, options
granted under the Plans may

     Pursuant to the Plans, unless otherwise determined by the compensation
committee, one-third of the options granted under the Plans are exercisable
upon grant, one-third are exercisable on the first anniversary of such grant
and the final one-third are exercisable on the second anniversary of such
grant. However, options granted under the Plans shall become immediately
exercisable if the holder of such options is terminated by the Company or is no
longer a director of the Company, as the case may be, subsequent to certain
events which are deemed to be a "change in control" of the Company.

NOTE 12--STOCK OPTION PLANS--(CONTINUED)
     The Company accounts for the fair value of its grants under those plans in
accordance with Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" whereby no compensation cost related to stock
options is deducted in determining net income. Had compensation cost for the
Company's stock option plans been determined pursuant to Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS
123"), the Company's net income and earnings per share would have decreased
accordingly. Using the Black-Scholes option pricing model, the Company's pro

fair value of options granted, with related assumptions, are as follows:

NOTE 14--SUBSEQUENT EVENTS


     On March 6, 1998 the Company completed the acquisition of Caribe Aviation,
Inc. (Caribe) and Caribe's wholly owned subsidiary Aircraft Interior Design,
Inc. ("Aircraft"). The purchase price was approximately $25 million, consisting
of $5 million in cash, and $5 million in promissory notes payable over two
years; the issuance of 182,143 shares of the Company's authorized, but
unissued, common stock; and the repayment of approximately $7.5 million of
indebtedness owed by Caribe and Aircraft to a financial institution. The
acquisition will be accounted for using the purchase method of accounting and
accordingly, the purchase price will be allocated to the assets purchased and
the liabilities assumed based upon the fair market value at the date of
acquisition. The estimated excess of the purchase price over the fair values of
the net assets acquired is approximately $10.7 million. This amount will be
recorded as goodwill and will be amortized on a straight-line basis over 20
years. The operations of Caribe and Aircraft will be included in the Company's
consolidated financial statements from the date of acquisition. Caribe and
Aircraft had consolidated fiscal 1997 revenues of approximately $27 million.
The pre-acquisition operations of Caribe are not material to the operations of
the Company.


     On February 17, 1998, the Company completed the offering and sale of $165
million in senior subordinated notes (the "Notes") due in 2008 with a coupon
rate of 8.125% at a price of 99.395%. Proceeds were used to repay debt and for
general corporate purposes, including acquisitions, working capital needs and
capital expenditures. In connection with this transaction, the Company will
write off the deferred financing costs related to term loan agreements
eliminated with the proceeds from the senior subordinated notes. The Notes are
unconditionally guaranteed, on a senior subordinated basis, by substantially
all of the Company's existing subsidiaries.


     On March 13, 1998, the Company entered into an agreement to purchase its
Pearland, Texas warehouse facility from a related party (see Note 6). The total
purchase price of approximately $1.8 million was paid in cash and through the
reduction of amounts receivable from the related party at the date of the
transaction.


     On March 26, 1998, the Company entered into a definitive agreement with
Whitehall Corporation, pursuant to which the two companies will merge. Under
the terms of the agreement, at the effective date of the merger, the
shareholders of Whitehall will receive 0.5143 shares of Aviation Sales common
stock for each share of Whitehall stock outstanding on such date. Based on the
approximately 6.0 million Whitehall shares outstanding, Aviation Sales will
issue approximately 3.1 million shares of Aviation Sales' common stock to
Whitehall's stockholders in the merger transaction. Based upon the closing
price of Aviation Sales' common stock on March 25, 1998, the value of the
transaction is approximately $142 million, which includes the assumption of
approximately $9.4 million of Whitehall's outstanding indebtedness. The
transaction, which will be accounted for as a pooling of interest, is expected
to close at the end of the second quarter of 1998. Whitehall had fiscal 1997
revenues of approximately $65.8 million.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 1998
                                  (UNAUDITED)


1. BASIS OF PRESENTATION:


INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


     The accompanying unaudited interim condensed consolidated financial
statements have been prepared pursuant to the rules and regulations of the
Securities and Exchange Commission for reporting on Form 10-Q. Pursuant to such
rules and regulations, certain information and footnote disclosure normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. The accompanying
unaudited interim condensed consolidated financial statements should be read in
conjunction with the Company's December 31, 1997 financial statements and the
notes thereto included in the Company's Annual Report on Form 10-K for the year
ended December 31, 1997 (File No. 1-11775).


     In the opinion of management, the accompanying unaudited interim condensed
consolidated financial statements of Aviation Sales Company (the "Company")
contain all adjustments (consisting of only normal recurring adjustments)
necessary to present fairly the financial position of the Company as of March
31,1998 and the results of its operations and cash flows for the three month
periods ended March 31, 1998 and 1997. The results of operations and cash flows
for the three month period ended March 31, 1998 are not necessarily indicative
of the results of operations or cash flows which may be reported for the year
ending December 31, 1998.


ACCOUNTING ESTIMATES


     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.


RECENTLY ISSUED ACCOUNTING STANDARDS


     Statement of Financial Accounting Standards No. 128, "Earnings Per Share"
("SFAS 128"), is effective for fiscal years ending after December 15, 1997.
This statement specifies the computation, presentation and disclosure
requirements for earnings per share for entities with publicly held common
stock or potential common stock. Earnings per share have been restated to
comply with SFAS 128 for all periods presented.


     The Company adopted Statement of Financial Accounting Standards No. 130,
"Reporting Comprehensive Income" ("SFAS 130"), during the quarter ended March
31, 1998. SFAS 130 was issued by the Financial Accounting Standards Board in
June 1997 and establishes standards for the reporting and display of
comprehensive income and its components in a full set of financial statements.
The objective of SFAS 130 is to report a measure (comprehensive income) of all
changes in equity of an enterprise that result from transactions and other
economic events in a period other than transactions with owners. The adoption
of SFAS 130 did not have a material impact on the Company's consolidated
financial statements, as comprehensive income was equal to net income for all
periods presented.


     Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("SFAS 131"), was issued by
the Financial Accounting Standards

Board in June 1997. This statement establishes standards for reporting
information about operating segments in annual financial statements and
requires reporting of selected information about operating segments in interim
financial reports issued to shareholders. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. The Company will adopt SFAS 131 effective December 31, 1998.


2. ACQUISITIONS:


     On March 26, 1998, the Company entered into a definitive agreement with
Whitehall Corporation ("Whitehall"), pursuant to which the two companies agreed
to merge. Under the terms of the agreement, at the effective date of the
merger, the shareholders of Whitehall will receive 0.5143 shares of the
Company's common stock for each share of Whitehall stock outstanding on such
date. Based on the approximately 6.0 million Whitehall shares outstanding as of
March 31, 1998, the Company will issue approximately 3.1 million shares of the
Company's common stock to Whitehall's stockholders in the merger transaction.
Based upon the closing price of the Company's common stock on March 25, 1998,
the value of the transaction is approximately $142 million, which includes the
assumption of approximately $9.4 million of Whitehall's outstanding
indebtedness. The transaction, which will be accounted for as a pooling of
interest, is expected to close during the third quarter of 1998. Whitehall had
revenues of approximately $65.8 million for the fiscal year ended December 31,
1997. During the quarter ended March 31, 1998, the Company incurred merger
expenses of approximately $.7 million relating to the Whitehall transaction,
which are included in general and administrative expenses in the accompanying
condensed consolidated statement of income for such period.


     On March 6, 1998 the Company completed the acquisition of Caribe Aviation,
Inc. ("Caribe") and Caribe's wholly-owned subsidiary Aircraft Interior Design,
Inc. ("AIDI"). The purchase price paid by the Company to acquire Caribe and
AIDI was approximately $23.3 million, consisting of: (i) $5.0 million in cash,
(ii) $5.0 million in promissory notes payable over two years, (iii) the
issuance of 182,143 shares of the Company's authorized, but unissued, common
stock, and (iv) the repayment of approximately $7.6 million of indebtedness
owed by Caribe and AIDI to a financial institution. The acquisition has been
accounted for using the purchase method of accounting and accordingly, the
purchase price has been allocated to the assets purchased and the liabilities
assumed based upon the fair market value at the date of acquisition. The excess
of the purchase price over the fair values of the net assets acquired is
approximately $9.6 million. This amount has been recorded as goodwill and will
be amortized on a straight-line basis over 20 years. The operations of Caribe
and AIDI have been included in the accompanying condensed consolidated
financial statements from the date of acquisition. Caribe and AIDI contributed
approximately $2.2 million to the Company's first quarter 1998 operating
revenues. Caribe and AIDI had consolidated revenues of approximately $27
million for the fiscal year ended December 31, 1997. The pre-acquisition
operations of Caribe and AIDI were not material to the operations of the
Company.


     On December 31, 1997, the Company acquired Apex Manufacturing, Inc.
("Apex") for consideration of 238,572 shares of the Company's common stock. The
acquisition was accounted for using the pooling of interests method of
accounting and, accordingly, the accompanying condensed consolidated financial
statements have been restated to include the accounts of Apex.

2. ACQUISITIONS:--(CONTINUED)

     On October 17, 1997 the Company completed the acquisition of substantially
all of the assets of the business of Kratz-Wilde Machine Company, a Kentucky
corporation ("Kratz-Wilde") for a purchase price, including acquisition costs
and net cash acquired, of approximately $39.6 million in cash and notes and the
assumption of certain liabilities of Kratz-Wilde in the approximate amount of
$2.2 million. The acquisition was accounted for using the purchase method of
accounting and accordingly, the purchase price has been allocated to the assets
purchased and the liabilities assumed based upon the fair values at the date of
acquisition. The operations of Kratz-Wilde since the acquisition have been
included in the accompanying condensed consolidated financial statements from
the date of acquisition. Kratz-Wilde contributed approximately $10.5 million to
the Company's first quarter 1998 operating revenues. In connection with the
acquisition, the Company borrowed $40,000,000 of senior notes payable to
financial institutions, with the remainder of the acquisition price payable to
the prior owners over a two-year period (see Note 3).


     The Company's unaudited pro forma consolidated results of operations
assuming the Kratz-Wilde acquisition had occurred on January 1, 1997 are as
follows:

     On September 30, 1997, the Company acquired Aerocell Structures, Inc.
("Aerocell") for consideration of 620,970 shares of the Company's common stock.
The acquisition was accounted for using the pooling of interests method of
accounting and, accordingly, the accompanying condensed consolidated financial

3. NOTES PAYABLE:


     On October 17, 1997, the Company amended its banking agreement pursuant to
the terms of a Third Amended and Restated Credit Agreement (the "Third Amended
Credit Agreement"). Pursuant to the Third Amended Credit Agreement, the Company
obtained a credit facility consisting of (a) a term loan facility in a
principal amount of $18.6 million, and (b) a $131.4 million revolving loan,
letter of credit and acquisition loan facility (the "Third Amended Revolving
Credit Facility"), subject to an availability calculation based on the eligible
borrowing base (collectively, the Credit Facility"). The eligible borrowing
base includes certain receivables and inventories of the Company. The letter of
credit portion of the Third Amended Revolving Credit Facility is subject to a
$15 million sublimit and the acquisition loan portion of the Third Amended
Revolving Credit Facility was subject to a $40 million sublimit, with the
imposition of certain borrowing criteria based on the satisfaction of certain
debt ratios. The acquisition loan portion of the Third Amended Revolving Credit
Facility was converted into a term loan in October 1997 in connection with the
acquisition of Kratz-Wilde. The interest rate on the Third Amended Credit
Agreement is, at the option of the Company, (a) prime plus a margin, or (b)
LIBOR plus a margin, where the margin determination is made based upon the
Company's financial performance over the 12 month period (ranging from 0.0% to
1.25% in the event prime is utilized, or 1.50% to 2.75% in the event LIBOR is
utilized). At March 31, 1998, the margin was .25% for prime rate loans and
1.75% for LIBOR rate loans.

                                  (UNAUDITED)


3. NOTES PAYABLE:--(CONTINUED)

     In connection with the Company's February 1998 sale of $165.0 million in
senior subordinated notes, the Company repaid in full and terminated the term
loan and acquisition loan portions of the Credit Facility, and repaid in full
the then current balance of the Third Amended Revolving Credit Facility. The
Third Amended Revolving Credit Facility presently allows the Company to borrow
up to $91.4 million and terminates on July 31, 2002. The Third Amended Credit
Agreement contains financial and other covenants and mandatory prepayment
events, as defined. At March 31, 1998, the Company was in compliance with all
covenants of the Third Amended Credit Agreement. The Third Amended Credit
Agreement is secured by a lien on substantially all of the assets of the
Company. On March 31, 1998, the outstanding balance under the Third Amended
Revolving Credit Facility was approximately $25.2 million.


     In February 1998, in connection with the repayment of the term and
acquisition portions of the Credit Facility, the Company wrote off $981,428 of
deferred financing costs resulting in an extraordinary item, net of income
taxes, of $598,671.


     On February 17, 1998 the Company completed the offering and sale of $165
million in senior subordinated notes (the "Notes") due in 2008 with a coupon
rate of 8.125% at a price of 99.395%. Proceeds were used (as described above)
to repay all amounts then outstanding under the Company's term, acquisition and
revolving credit facilities and to fund the cash requirements related to the
acquisition of Caribe and AIDI. The Notes are unconditionally guaranteed, on a
senior subordinated basis, by substantially all of the Company's existing
subsidiaries.


     The Indenture contains certain covenants that, among other things, will
limit the ability of the Company and its subsidiaries to incur additional
indebtedness and issue preferred stock, pay dividends or make other
distributions, make investments, dispose of assets, issue capital stock of
subsidiaries, create certain liens securing indebtedness, enter into certain
transactions with affiliates, sell assets or enter into certain mergers and
consolidations or sell all or substantially all of their assets.


     In connection with the Company's March 9, 1998 acquisition of Caribe and
AIDI (see Note 2), the Company entered into an agreement with the prior owners
to pay $5 million of the acquisition price over a two year period. Principal
payments of $2,500,000 plus interest accrued at 8%, are due on March 9, 1999
and March 9, 2000.


     In connection with the October 17, 1997 acquisition of Kratz-Wilde (see
Note 2), the Company entered into an agreement with the prior owners to pay
$2.2 million of the acquisition price over a two year period. Payments of
$1,250,000 are due on January 1, 1999 and January 1, 2000. Interest on this
note has been imputed at 8%.


     On August 5, 1997, the Company entered into a term loan agreement in a
principal amount of $7.2 million to finance certain equipment and rotable parts
on long term lease which secure the loan. This loan is payable in 59
consecutive equal monthly payments of $91,750 commencing September 14, 1997,
with a final balloon payment due on August 14, 2002. Interest on this term loan
is fixed at 8.21%. The Company has leased the underlying equipment and rotable
parts to unrelated third parties. Interim payments under the term loan will be
made from the proceeds of these parts leases. This term loan

price of approximately $1.8 million was paid in cash and through the reduction
of amounts receivable from the related party at the date of the transaction.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


Board of Directors and Stockholders Kratz-Wilde Machine Company:


     We have audited the accompanying balance sheets of Kratz-Wilde Machine
Company (an S Corporation) as of October 31, 1996 and 1995, and the related
statements of income, retained earnings, and cash flows for the year ended
October 31, 1996. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.


     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Kratz-Wilde Machine Company
as of October 31, 1996 and 1995, and the results of its operations and its cash
flows for the year ended October 31, 1996 in conformity with generally accepted
accounting principles.


     As discussed in Note 8 to the financial statements, certain misstatements
of previously reported inventories as of October 31, 1996 and 1995 were
discovered. Accordingly, an adjustment has been made to net income for 1996 and
retained earnings as of October 31, 1995 to correct the misstatements.

                         NOTES TO FINANCIAL STATEMENTS


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:


     The following accounting practices of the Company are set forth to
facilitate the understanding of data in the financial statements.


NATURE OF OPERATIONS


     The Company's line of business is the manufacture of metal stampings which
are principally sold to customers in the aircraft, plumbing and automotive
manufacturing industries located in the United States.


CASH EQUIVALENTS


     For purposes of the statement of cash flows, cash equivalents consist of
money market accounts.


TEMPORARY INVESTMENTS


     Temporary investments consist of debt securities (principally certificates
of deposit, repurchase agreements and U.S. Treasury bills) with maturities of
less than one year. Such investments are intended to be held to maturity and
therefore are carried at amortized cost.


INVENTORIES


     Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method.


BAD DEBTS


     Accounts receivable have been adjusted for all known uncollectible
accounts. No allowance for bad debts is considered necessary by management at
year end.


PROPERTY AND DEPRECIATION


     Property and equipment is stated at cost. The Company provides for
depreciation of property and equipment using annual rates which are sufficient
to amortize the cost of depreciable assets over their estimated useful lives,
which range from three to forty-five years. The Company uses both the straight-
line and accelerated methods of depreciation.


SPLIT DOLLAR LIFE INSURANCE


     The Company records as an asset premiums paid under the split-dollar life
insurance arrangement at the lower of the policy's cash value or the premiums
paid by the Company through the balance sheet date.


USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS


     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

INCOME TAXES


     The Company has elected, effective November 1, 1988, to be taxed under
provisions of Subchapter S of the Internal Revenue Code. Under those
provisions, the Company will generally not pay Federal, Ohio or Kentucky
corporate income taxes on its taxable income. Instead, each stockholder will be
liable for individual federal and state income taxes on the Company's taxable
income.


     The Company can be liable for a tax on "built-in" gains until November 1,
1988. "Built-in" gains can arise if certain appreciated assets which were held
at the time of the effective date of the S election are subsequently disposed
of within 10 years.


     Deferred income taxes were previously recorded for timing differences
between financial and tax reporting. Deferred income taxes resulted principally
from the use of accelerated methods of depreciation for tax purposes and the
restoration of the LIFO inventory reserve to taxable income as a result of
electing S Corporation status. No additional deferred income taxes will be
provided on future timing differences. However, because of the possibility of a
"built-in" gains tax in the future, the Company will continue to recognize the
deferred tax liability, arising before 1989, net of any federal income tax
subsequently incurred.


RELATED PARTIES


     Officers of the Company own 100% of the Company's capital stock
outstanding.


INTERIM CONDENSED FINANCIAL STATEMENTS


     The accompanying unaudited interim financial statements have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission
for reporting on Form 8-K/A. Pursuant to such rules and regulations, certain
information and footnote disclosure normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted.


     In the opinion of management, the accompanying unaudited interim financial
statements of Kratz-Wilde Machine Company (the "Company") contain all
adjustments (consisting of only normal recurring adjustments) necessary to
present fairly the financial position of the Company as of September 30, 1997
and the results of its operations and cash flows for the nine month periods
ended September 30, 1997 and 1996. The results of operations and cash flows for
the nine month period ended September 30, 1997 are not necessarily indicative
of the results of operations or cash flows which may be reported for the year
ending December 31, 1997.


2. CASH, CASH EQUIVALENTS AND TEMPORARY INVESTMENTS:


     The Company maintains their cash deposit accounts at financial
institutions where the balances at times may exceed federally insured limits.
As of the reporting dates, cash, cash equivalents and temporary investments
consist of:

                                        ========
</TABLE>

     The estimated fair value of the above debt securities approximates cost at
October 31, 1995.


3. CONCENTRATION OF CREDIT RISK:


     The Company sells products to manufacturers and extends credit based on an
evaluation of the customer's financial condition, without collateral. Exposure
to losses on receivables is principally dependent on each customer's financial
condition. The Company monitors its exposure to credit losses and maintains
allowances, when necessary, for anticipated losses.


     Three major customers accounted for sales of approximately 75% for the
nine months ended September 30, 1997 and 1996 and the year ended October 31,
1996. Accounts receivable due from these customers were approximately $4.4
million and $3.8 million at September 30, 1997 and October 31, 1996,
respectively.


4. TAX DEPOSIT:


     As a corporation that has retained a fiscal year end, the Company is
required to maintain a deposit with the Internal Revenue Service while the S
Corporation election is in effect. This deposit is recalculated annually based
on the preceding year's taxable income. The Company's total deposit balance,
related to the S Corporation election, was $178,085 at September 30, 1997,
$151,525 at October 31, 1996 and $209,807 at October 31, 1995.

6. PROFIT SHARING PLAN:


     The Company sponsors a profit sharing plan covering employees who are at
least 21 years of age with a minimum of one year of service. The Board of
Directors of the Company determines the annual contribution, which may not
exceed 15% of the qualifying employees' compensation. Profit sharing plan
expense was $568,087 and $426,801 for the nine months ended September 30, 1997
and 1996, respectively, and $569,067 for the year ended October 31, 1996.


7. COMMITMENTS:


DISTRIBUTIONS


     It is anticipated that the Company will make cash distributions to the
stockholders since they are liable for individual federal and state income
taxes on the Company's taxable income. No additional distributions, in excess
of the amounts recorded in the accompanying financial statements, have been
declared as of September 30, 1997 or October 31, 1996. Accordingly, no S
distribution payable is recognized in the accompanying financial statements.


LIFE INSURANCE PROGRAM


     In 1995, the Company implemented a split dollar life insurance
arrangement. The Company will pay most of the premium cost which will be
approximately $50,000 per year. These premiums are expected to be repaid to the
Company. The Company does not own the policies but does hold a collateral
assignment that effectively pledges the policies' cash values and death
proceeds as security for the return of the premiums paid by the Company. The
cash values are expected to eventually exceed the cumulative premiums paid. The
Company's recovery of the premiums paid is contingent upon continuation of the
life insurance program in the future.


     The Company is the owner and beneficiary of other life insurance policies
under a buy-sell agreement between the stockholders. The Company's annual
premium cost under this arrangement is approximately $40,000 per year.


8. INVENTORIES:


     Subsequent to issuance of the reviewed financial statements for the year
ended October 31, 1996 it was determined that inventory was overstated.
Correction of these estimated misstatements resulted in a decrease of
previously reported net income for 1996 amounting to $783,000 and a decrease to
retained earnings as of October 31, 1995 amounting to $702,000. The cumulative
effect of these changes was to decrease retained earnings as of October 31,
1996 by $1,485,000.

9. CONTINGENCY:


     The Company is a defendant in lawsuits arising from normal business
activities. Outside counsel for the Company has advised that at this stage they
cannot offer an opinion as to their probable outcome. Management has reviewed
pending litigation and believes that the ultimate liability, if any, resulting
from them will not materially affect the Company's financial position.
Nevertheless, it is at least reasonably possible that such an effect will
occur, although the amount cannot be estimated.


10. SUBSEQUENT EVENT:


     The Company agreed in September 1997 to sell principally all of its
operating assets for $42.5 million. All of the Company's operations will be
transferred to the new owner.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Whitehall Corporation and Subsidiaries:


     We have audited the accompanying consolidated balance sheets of Whitehall
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1997
and 1996, and the related consolidated statements of operations, shareholders'
equity, and cash flows for the three years in the period ended December 31,
1997. These consolidated financial statements and the schedule referred to
below are the responsibility of the Company's management. Our responsibility is
to express an opinion on these financial statements and schedule based on our
audits.


     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Whitehall Corporation and
subsidiaries as of December 31, 1997 and 1996, and the results of its
operations and its cash flows for the three years in the period ended December
31, 1997, in conformity with generally accepted accounting principles.


     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index to
financial statements is presented for purposes of complying with the Securities
and Exchange Commission's rules and is not part of the basic financial
statements. This schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, fairly
states in all material respects the financial data required to be set forth
therein in relation to the basic financial statements taken as a whole.

     USE OF ESTIMATES: Generally accepted accounting principles require
management to make estimates and assumptions that affect the reported amount of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.


     RECLASSIFICATIONS: Certain reclassifications have been made to 1996 and
1995 amounts to conform with the 1997 presentation.


     LONG-TERM CONTRACTS: Revenue on long-term contracts in 1996 and 1995 is
recognized using the percentage of completion or unit of delivery method. On
contracts where the percentage of completion method is applied, revenue is
accrued in the proportion that costs incurred bear to management's estimate of
total contract costs. Any known or anticipated losses are provided for
currently.


     CONCENTRATION OF CREDIT RISK: Financial instruments which potentially
subject the Company to concentrations of credit risk consist principally of
temporary cash investments and accounts receivable. The Company places its
temporary cash investments with creditworthy financial institutions and, thus,
limits the amount of credit exposure to any one entity. The Company's customer
base is comprised primarily of U.S. airlines and air transport companies.


     CASH EQUIVALENTS: Cash equivalents consist of highly liquid debt
instruments purchased with an original maturity of three months or less.


     INVENTORIES: Inventories are carried at average cost, not in excess of
market.


     PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment is stated at
cost. Provisions for depreciation and amortization have been computed generally
using the straight-line method over the estimated useful lives of the assets.


     LONG-LIVED ASSETS: The Company periodically reviews its long-lived assets
for impairment. If this review indicates that the carrying amount of an asset
may not be recovered through future operations or sale, the carrying value of
the asset will be reduced to its fair value. In 1997, the Company recorded an
impairment loss on its investment in preferred stock (see Note D).


     RESEARCH AND DEVELOPMENT: Research and development costs are included in
selling, engineering and administrative expenses and amounted to approximately
$41,000 in 1996, and $45,000 in 1995. There were no research and development
costs incurred in 1997.


     FEDERAL INCOME TAXES: The Company accounts for income taxes using an asset
and liability approach for financial accounting and income tax reporting.
Deferred tax liabilities and assets are recognized for the estimated future tax
effects attributable to temporary differences and carryforwards and are
adjusted whenever tax rates or other provisions of income tax statutes change.


     The Company and all subsidiaries file a consolidated Federal income tax
return. Deferred federal income taxes have been provided for temporary
differences between tax and financial reporting resulting primarily from
depreciation provisions, allowances and expense accruals.

     EARNINGS (LOSS) PER SHARE: Effective January 1, 1997, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per
Share." SFAS No. 128 simplifies the computation of earnings per share (EPS) by
replacing the presentation of primary EPS with a presentation of basic EPS.
Basic EPS is calculated by dividing the income (loss) available to common
shareholders by the weighted average number of common shares outstanding during
the period. Options and other potentially dilutive securities are excluded from
the calculation of basis EPS. Diluted EPS includes options and other
potentially dilutive securities that are excluded from basic EPS to the extent
that these securities are not anti-dilutive. Options were not included in the
1997 computation of diluted EPS because they are anti-dilutive.


     The following is a reconciliation between basic and diluted EPS for the
years ended December 31, 1997, 1996, and 1995:

     In accordance with SFAS No. 128, the earnings (loss) per share for all

  JOINT VENTURE INVESTMENT: SEE NOTE D.


     TREASURY SHARES: During 1991, the Board of Directors authorized the
repurchase of up to 1,000,000 shares of the Company's common stock. An
additional authorization of 500,000 shares was made by the Board of Directors
in March 1993. As of December 31, 1997, a total of 1,257,800 shares have been
purchased under these authorizations. The Company did not acquire any treasury
stock during 1995, 1996 or 1997.


     ENVIRONMENTAL COSTS: Environmental expenditures that relate to current
operations are expensed. Remediation costs that relate to existing conditions
caused by past operations are accrued when it is probable that these costs will
be incurred and can be reasonably estimated. Environmental costs are included
in selling, engineering and administrative expenses in the accompanying
consolidated statements of operations.


     OTHER INCOME (EXPENSE): Other expense for 1997 includes the $4.5 million
writedown of the Company's investment in the preferred stock of Hydroscience
Technologies, Inc. Other income, net in 1996 and 1995 includes interest earned
of $307,000 and $671,000, respectively, and gains on sales of fixed assets of
$11,000 and $650,000, respectively.


     EMPLOYEE BENEFITS: The Company offers no significant post-employment or
post-retirement benefits.


     NEW ACCOUNTING PRONOUNCEMENTS: During 1997, the Financial Accounting
Standards Board (FASB) issued SFAS No. 129, "Disclosure of Information About
Capital Structure," which establishes standards

NOTE A--ACCOUNTING POLICIES AND PRACTICES--(CONTINUED)

for disclosing certain information about an entity's capital structure. The
statement is effective for years ending after December 15, 1997, and its
adoption did not have any impact on the Company's financial statements.


     During 1997, FASB issued SFAS No. 130, "Reporting Comprehensive Income,"
which establishes standards for reporting and display of comprehensive income
and its components (revenues, expenses, gains, and losses) in a company's
financial statements. This statement requires that all items that are required
to be recognized under accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements. This Statement does not require a
specific format for that financial statement but requires that an enterprise
display an amount representing total comprehensive income for the period in
that financial statement. This statement requires that an enterprise (a)
classify items of other comprehensive income by their nature in a financial
statement and (b) display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in the equity
section of a statement of financial position. SFAS No. 130 is effective for
periods beginning after December 15, 1997.


     During 1997, FASB issued SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information." This Statement is effective for financial
statements for periods beginning after December 15, 1997. As the Company is
operating in only one segment as of December 31, 1997, and plans to focus
solely on the aircraft maintenance industry, this statement is not expected to
have an impact on the Company's financial statements.

NOTE D--INVESTMENTS


     In November 1996, the Company sold substantially all of the assets related
to its Ocean Systems segment to Hydroscience Technologies, Inc. ("HTI") in
exchange for 818,182 shares of HTI Preferred Stock, which carries a liquidation
preference of $5.50 per share. At the Company's election, the HTI Preferred
Stock is convertible after December 31, 1997, into 45% of HTI's Common Stock.
(See Note P for pro forma information related to this transaction.) Although
the purchaser of Ocean Systems provided additional capital and new management,
the continuing decline in defense spending and other concerns caused management
to reevaluate this preferred stock in 1997. Management has concluded that the
value of its investment has declined permanently. The entire amount was written
off in 1997.


     During 1994, the Company obtained 40% ownership of a joint venture
involved in the development of aircraft-related technology for an initial
investment of $1,000. The Company accounts for its investment in the joint
venture under the equity method. In 1994, the Company obtained a promissory
note for an advance of $2,000,000 to the joint venture. The principal balance
of the promissory note accrues interest at a maximum rate of 5% per annum and
the principal balance with accrued interest is due January 5, 1999. The note is
secured by certain assets of the joint venture. During 1997 and 1996, the
Company advanced an additional $815,000 and $75,000 to the joint venture. These
advances are included in accounts receivable.

NOTE F--LONG-TERM DEBT


     The Company entered into a long-term note and a credit facility during
1996 with a bank. The credit facility consists of a $12,000,000 line of credit
agreement and a $3,000,000 standby letter of credit agreement. Advances under
the line of credit agreement accrue interest at the prime interest rate (8.5%
at December 31, 1997). The Company also pays an annual commitment fee of 1/4 of
1 % on the unused portion of the line of credit. At December 31, 1997, the
unused and available portion of the line of credit was $2,287,000. The line of
credit expires on June 30, 1998. Management is confident that this line will be
renewed or comparable financing can be obtained at June 30, 1998, for at least
another one-year period.


     The credit facility is unsecured and contains certain financial covenants
related to working capital, consolidated net income and consolidated tangible
net worth, among other restrictions. The Company was in violation of certain
covenants as of December 31, 1997; however, these covenants have been waived by
the bank.

1999, and zero thereafter.


     A $1,700,000 standby letter of credit was issued, pursuant to the standby
letter of credit agreement, in order to comply with the annual financial
assurances required by the Florida Department of Environmental Protection and
related to the environmental remediation being performed at the Company's Lake
City, Florida facility (see Note O). The standby letter of credit agreement has
an annual commitment fee of 1% of the amount of the letter of credit.


NOTE G--SHAREHOLDERS' EQUITY


     On January 29, 1997, the Board of Directors declared a 2 for 1 stock split
to be effected in the form of a 100% stock dividend to shareholders of record
at the close of business March 25, 1997. The dividend resulted in $384,000
being transferred from retained earnings to common stock. This amount
represents the par value of the new stock. All share and per share amounts have
been adjusted to recognize this dividend.


     On March 17, 1997, the shareholders approved an amendment to the Company's
Restated Certificate of Incorporation increasing the number of authorized
shares of Common Stock from 5,000,000 shares to 20,000,000 shares.

     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred tax assets and liabilities as of December 31, 1997
and 1996 are as follows:

     The Company has established a valuation allowance to offset the deferred
tax assets that have resulted from items that will only be deductible when such
items are actually incurred. The valuation allowance will be maintained until
it is more likely than not that these deferred tax assets will be realized.

NOTE I--STOCK OPTION PLANS


     In May 1992, the stockholders approved the Whitehall Corporation Incentive
Stock Option Plan ("Incentive Plan") and the Whitehall Corporation Non-Employee
Directors Stock Option Plan ("Directors Plan"). The Incentive Plan provides for
the grant of incentive stock options for up to 650,000 shares of Common Stock
to key employees. The Directors Plan provides for the grant of incentive stock
options for up to 130,000 shares of Common Stock to non-employee Directors of
the Company. Under the Plans, the exercise price for stock options will not be
less than the fair market value of the optioned stock at the date of grant.
Stock options expire ten years from the date of grant and generally vest over a
five-year period with one-fifth of the shares becoming exercisable on each of
the five anniversaries of the date of grant. As December 31, 1997, 1996, and
1995 there were 347,100, 218,600, and 196,200 options exercisable,
respectively. The option period under both Plans may not be more than ten years
from the date the option is granted.


     Transactions involving the Plans are summarized as follows:

NOTE I--STOCK OPTION PLANS--(CONTINUED)

     The Company accounts for its stock option plans in accordance with
Accounting Principles Board Opinion No. 25, under which no compensation cost
has been recognized for stock option awards. In 1996, the Company adopted SFAS
No. 123, which requires that options be priced using the fair value method, and
has elected the disclosure only alternative. The fair value of each stock
option grant is estimated on the date of grant using the Black-Scholes option
pricing model. Using the fair value method to determine compensation costs, the
Company's pro forma net income and net income per share would be:

     Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years.


NOTE J--SAVINGS PLAN


     The Company implemented a voluntary 401(k) savings plan for eligible
employees (as defined by the Plan document) effective September 1, 1992. The
Company contributed $50 per enrolling employee in 1995. The Company contributes
50% of employee contributions up to 1.5% of the employee's base salary. The
Company may make future matching contributions at its discretion. Company
contributions totaled approximately $86,000 in 1997, $40,000 in 1996, and
$25,000 in 1995. The Company's contributions vest over a six-year period.

1996.


NOTE O--COMMITMENTS AND CONTINGENCIES


ENVIRONMENTAL MATTERS


     The Company's operations, like those of other companies engaged in similar
businesses, are subject to extensive and evolving federal, state, and local
environmental laws and regulations. The measurement of environmental
liabilities is based on an evaluation of currently available facts with respect
to each individual site and considers factors such as existing technology,
presently enacted laws and regulations, and prior experience in remediation of
contaminated sites. As assessments and remediation progress at individual
sites, these liabilities are reviewed and adjusted to reflect the additional
technical and legal information as it becomes available. In order to comply
with present federal, state and local provisions which have been enacted or
adopted regulating the discharge of materials into the environment, or
otherwise relating to the protection of the environment, the Company will be
required to fund remediation efforts, which could result in potentially
substantial operating costs and capital expenditures.


     The Company is taking remedial action pursuant to Environmental Protection
Agency ("EPA") regulations at the Lake City, Florida facility. Ongoing testing
is being performed and new information is being gathered to continually assess
the impact and magnitude of the required remediation efforts on the Company.
Based upon the most recent cost estimates provided by environmental
consultants, the Company believes that the total remaining remediation and
compliance costs for this facility will be approximately $2.4 million, which
has been accrued at December 31, 1997.


     Additionally, there are other areas on the Lake City property that could
also require remediation. The Company believes it is not responsible for these
areas; however, it may be required to take part in the remediation process to
continue its operations at that location. No estimate of any such costs to the
Company is available at this time.


     In connection with the sale of Crystek (see Note L), Whitehall was
required to perform, at its own expense, an environmental site assessment at
the Crystek facility. The Company is also required to remedy all recognized
environmental conditions identified in the assessment to bring the Crystek
facility into compliance with all applicable Federal, State, and local
environmental laws. If the facility is not brought into compliance with
environmental laws by December 31, 1998, the buyer shall have the option of
requiring the Company to repurchase the property. The Company has engaged
environmental consultants to review potential environmental liabilities at the
Crystek facility. Such investigation and testing resulted in the identification
of likely environmental remedial actions. Based upon the cost estimates
provided by the consultants, the Company believes that the total remediation
and compliance costs for this facility will be approximately $1.0 million,
which has been accrued at December 31, 1997.


     Future information and developments will require the Company to
continually reassess the expected impact of the environmental matters discussed
above. Actual costs to be incurred in future

NOTE O--COMMITMENTS AND CONTINGENCIES--(CONTINUED)

periods may vary from the estimate, given the inherent uncertainties in
evaluating environmental exposures. These uncertainties included the extent of
required remediation based on testing and evaluation not yet completed and the
varying costs and effectiveness of remediation methods.


     To comply with the financial assurances required by the Florida Department
of Environmental Protection (FDEP), the Company requested and a bank issued a
$1,700,000 standby letter of credit in favor of the FDEP. This letter of credit
meets all conditions required by the FDEP.



LEGAL MATTERS


     On May 10, 1991, an action was filed in the District Court of Dallas
County, Texas, by Lee D. Webster, former Chairman, Chief Executive Officer and
President of Whitehall, against the Company, each of its directors (other than
Mr. Webster) and Cambridge Capital Fund, L.P., alleging, among other things,
that (i) the defendants' actions, both individually and in concert, constituted
willful interference with Mr. Webster's employment relationship with the
Company and was the direct cause of Mr. Webster's termination as its President
and Chairman of the Board, and (ii) the defendants' actions forced Mr. Webster
into retirement without providing Mr. Webster with retirement benefits which
Mr. Webster was purportedly promised. On August 17, 1994, the defendants were
granted a partial summary judgment. On October 24, 1994, Mr. Webster filed a
third amended petition and alleged the following causes of action: tortuous
interference with contractual relations against Cambridge Capital Fund, L.P.,
and directors George F. Baker and John J. McAtee; intentional infliction of
emotional distress and breach of oral contracts. The third amended petition
sought compensatory and punitive damages in excess of $35 million. On January
12, 1995, the Court entered an abatement on one of the breach of oral contract
claims against the Company and entered a summary judgment in the defendants'
favor on all remaining claims alleged by Mr. Webster. On February 26, 1996, the
Court granted a summary judgment in favor of the defendants on Mr. Webster's
remaining claims and entered a take nothing final judgment which dismissed all
of Mr. Webster's claims with prejudice to refiling. On March 26, 1996, Mr.
Webster appealed the final judgment to the Dallas, Texas Court of Appeals. Oral
argument was held on November 13, 1997. To date, no decision has been reached
by the court. Management intends to vigorously defend this appeal.


     The Company is also involved in certain legal proceedings in the normal
course of its business. After consultation with counsel, management is of the
opinion that the outcome of the above-mentioned proceedings will not have a
material effect on the financial position or results of operations of the
Company.

NOTE Q--RELATED PARTY TRANSACTIONS

     As of December 31, 1997, two former officers of the Company were indebted
to the Company in the aggregate amount of approximately $363,000. This amount
is classified as accounts receivable and is fully reserved. These receivables
will be written off in 1998.

NOTE R--SUBSEQUENT EVENT

     In March 1998, the Company entered into a definitive agreement with
Aviation Sales Company (AVS). Under the terms of the agreement, the Company
will exchange its common stock for common stock of AVS. This transaction is
expected to be accounted for as a pooling of interests.

                         PART I--FINANCIAL INFORMATION
                     WHITEHALL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

                                 MARCH 31, 1998


1. BASIS OF PRESENTATION:


     The accompanying unaudited condensed consolidated financial statements
include the accounts of Whitehall Corporation and those of all of its
majority-owned subsidiaries ("Whitehall" or the "Company") and have been
prepared in accordance with Form 10-Q instructions and thus do not include all
of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments considered necessary for a fair presentation have been included.


     Operating results for the three month period ending March 31, 1998, are
not necessarily indicative of the results that may be expected for the entire
year.


     During February of 1997, the Financial Accounting Standards Board issued
SFAS No. 128, Earnings per Share, which became effective for all financial
statements issued for periods ending after December 15, 1997, including interim
periods. SFAS No. 128 provides for the presentation of basic and diluted
earnings per share on the face of the financial statements and supersedes
Accounting Principles Board (APB) Opinion No. 15, Earnings per Share. SFAS No.
128 requires the restatement of earnings per share for prior periods presented
after its effective date. Earnings per share for the three month periods ended
March 31, 1998 and 1997 have been computed under SFAS No. 128.


     For further information, refer to the consolidated financial statements
and footnotes thereto included in the Company's Annual Report on Form 10-K for
the year ended December 31, 1997.


2. JOINT VENTURE:


     During 1994, the Company obtained a 40% ownership in AvAero Noise
Reduction Joint Venture ("AvAero"), a joint venture involved in the development
of aircraft-related technology for an initial investment of $1,000. The Company
accounts for its investment in AvAero under the equity method. In 1994, the
Company obtained a promissory note for an advance of $2,000,000 to the joint
venture. The principal balance of the promissory note accrues interest at a
maximum rate of 5%, and the principal balance together with accrued interest
are due January 5, 1999. The note is secured by certain assets of AvAero.
During 1997, 1996 and 1995 the Company advanced an additional $476,000, $75,000
and $1,020,000 to AvAero, net of repayments. The Company has made no further
advances since 1997. These advances are included in accounts receivable.


3. COMMITMENTS AND CONTINGENCIES:


     On May 10, 1991, an action was filed in the District Court of Dallas
County, Texas, by Lee D. Webster, former Chairman, Chief Executive Officer and
President of Whitehall, against the Company, each of its directors (other than
Mr. Webster) and Cambridge Capital Fund, L.P., alleging, among other things,
that (i) the defendants' actions, both individually and in concert, constituted
willful interference with Mr. Webster's employment relationship with the
Company and were the direct cause of Mr. Webster's termination as its President
and Chairman of the Board, and (ii) the defendants' actions forced Mr. Webster
into retirement without providing Mr. Webster with retirement benefits which
Mr. Webster was purportedly promised. On August 17, 1994, the defendants were
granted a partial

summary judgment. On October 24, 1994, Mr. Webster filed a third amended
petition and alleged the following causes of action: tortious interference with
contractual relations against Cambridge Capital Fund, L.P., and directors
George F. Baker and John J. McAtee; intentional infliction of emotional
distress; and breach of oral contracts. The third amended petition sought
compensatory and punitive damages in excess of $35 million. On January 12,
1995, the Court entered an abatement on one of the breach of oral contract
claims against the Company and entered a summary judgment in the defendants'
favor on all remaining claims alleged by Mr. Webster. On February 26, 1996, the
Court granted a summary judgment in favor of the defendants on Mr. Webster's
remaining claim and entered a take nothing final judgment which dismissed all
of Mr. Webster's claims with prejudice to refiling. On March 26, 1996, Mr.
Webster appealed the final judgment to the Dallas, Texas Court of Appeals. On
April 10, 1998 the Texas Court of Appeals affirmed the trial court's summary
judgement ruling in favor of the defendants on each of Mr. Webster's claims.


     A subsidiary of the Company, Aero Corporation ("Aero"), is taking remedial
action pursuant to Environmental Protection Agency ("EPA") regulations at the
Lake City, Florida facility. In addition, the Company was required to perform
an environmental site assessment at the facility of a subsidiary in connection
with the sale of the facility during the first quarter of 1997. The Company
does not anticipate any material direct effects upon the capital expenditures,
earnings and competitive position of the Company from compliance with present
Federal, State and local provisions which have been enacted or adopted
regulating the discharge of materials into the environment, or otherwise
relating to the protection of the environment in excess of the Company's
reserves.


     The Company does expect, however, that compliance with such regulations
will require, from time to time, both increased operating costs and capital
expenditures which may be substantial. As of March 31, 1998 and December 31,
1997, the Company had reserved ,in the aggregate, approximately $3.95 million
for anticipated environmental remediation costs. Included among the remaining
costs to be incurred are anticipated expenditures for testing and monitoring to
be performed over a 20 to 30 year period. Actual costs to be incurred in future
periods may vary from the estimate, given the inherent uncertainties in
evaluating environmental exposures. These uncertainties include the extent of
required remediation based on testing and evaluation not yet completed and the
varying costs and effectiveness of remediation methods.


     The Company is also involved in certain legal proceedings in the normal
course of its business. After consultation with counsel, management is of the
opinion that the outcome of the above-mentioned proceedings will not have a
material effect on the financial position or results of operations of the
Company beyond the amounts currently reserved.


4. ACQUISITIONS AND MERGERS:


     In March of 1998, the Company entered into a definitive merger agreement
(the "Merger Agreement") with Aviation Sales Company ("AVS") pursuant to which
a wholly-owned subsidiary of AVS will merge (the "Merger") with and into the
Company. As a result of the Merger, the Company will become a wholly owned
subsidiary of AVS. The Merger is expected to be accounted for as a

pooling of interests. Under the terms of the Merger Agreement, each share of
the Company's common stock outstanding at the effective time of the Merger will
be converted into the right to receive .5143 shares of common stock of AVS.
Consummation of the Merger, which is expected to occur at the end of the second
quarter of 1998, is subject to customary closing conditions, including, without
limitation, approval of the Company's and AVS's stockholders. No assurance can
be given that the Merger will ultimately be consummated or that it will be
consummated on the terms set forth in the Merger Agreement.


     In July 1997, Whitehall purchased from Zantop International Airlines, Inc.
("Zantop") certain assets (the "Acquired Assets") used in connection with the
operation of Zantop's third party aircraft maintenance business located in
Macon, Georgia. Among the Acquired Assets were all of Zantop's leasehold
interest in the properties located at its Macon facility (the "Leased
Facilities"). The purchase price for the Acquired Assets was $1.5 million in
cash plus assumption of certain liabilities, including approximately $4.3
million in future lease obligations relating to the Leased Facilities.

     NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
                                  (UNAUDITED)


(1) Caribe was acquired on March 6, 1998, in a transaction accounted for as a
    purchase. The historical operations of Caribe are included in AVS's
    historical results of operations since the acquisition date. The unaudited
    pro forma information for the three months ended March 31, 1998 has been
    prepared assuming the Merger occurred as of January 1, 1998 for statement
    of operations data. The unaudited pro forma information does not give
    effect to the acquisition of Caribe due to the immateriality of the
    amounts.


(2) The 1997 unaudited pro forma information has been restated to reflect the
    1997 acquisitions of Apex and Aerocell, which were accounted for as
    poolings of interests. Kratz was acquired on October 17, 1997, in a
    transaction accounted for as a purchase. The historical operations of
    Kratz are included in AVS's historical results of operations since the
    acquisition date. The unaudited pro forma information for the year ended
    December 31, 1997 has been prepared assuming the Merger and the
    acquisition of Kratz occurred as of January 1, 1997 for statement of
    operations data. The purchase price paid for Kratz and its allocation to
    the net assets acquired is as follows:

   The excess of the purchase price over the fair values of the net assets
   acquired from Kratz has been recorded as goodwill, which is being amortized
   on a straight-line basis over 20 years.


(3) The 1995 and 1996 unaudited pro forma information is presented to show the
    effect of the Merger under the pooling of interests method of accounting.
    The 1996 unaudited pro forma information has been restated to reflect the
    1996 acquisition of AvEng, which was accounted for as a pooling of
    interests. Dixie was acquired on August 9, 1996, in a transaction
    accounted for as a purchase and accordingly its results of operations are
    included since that date. Pro forma adjustments to record the
    pre-acquisition results of operations of Dixie in 1996 have not been made
    due to the immateriality of the amounts. The 1995 and 1996 results of
    operations do not include Apex and Aerocell due to the immateriality of
    the amounts. The 1995 results of operations do not include AvEng due to
    the immateriality of the amounts.


(4) The following adjustments have been made to give pro forma effect to the
    Merger:


   (A) This calculation assumes the issuance of approximately 2,844,079 shares
        of AVS common stock in the Merger, which is calculated based on an
        exchange ratio of .5143 shares of AVS common stock for each share of
        Whitehall common stock outstanding at March 31, 1998. Pro forma book
        value per share common was computed by adding the 2,844,079 shares of
        AVS common stock to be issued in the Merger to the actual number of
        shares of AVS common stock outstanding at March 31, 1998.


                                      P-7
<PAGE>

   (B) To record the Merger under the pooling of interest method of accounting
        and reflect AVS's common stock to be issued in connection with the
        Merger including the retirement of the Whitehall treasury stock.


   (C) This calculation assumes the conversion of Whitehall's weighted average
        number of shares into the weighted average number of shares of AVS
        common stock, using an exchange ratio of .5143, for each respective
        period.


   (D) Periods presented prior to 1997 include pro forma adjustments to record
        income taxes of $4,011,432 and $6,604,188 for 1995 and 1996,
        respectively, as AVS conducted its business as a partnership prior to
        June 26, 1996.


   (E) To eliminate intercompany sales from AVS to Whitehall, net of income
       tax effect of $52,286, $84,690, $27,842 and $12,810 for 1995, 1996,
       1997 and the three months ended March 31, 1998, respectively.


   (F) The 1995 and 1996 AVS earnings per share assumes that the 4,425,000
       common shares issued to the partners of AJT Capital Partners (the
       predecessor business of AVS) and the 575,000 shares of common stock,
       the net proceeds in respect of which were paid to J/T Aviation
       Partners, were outstanding for periods prior to the closing of AVS's
       initial public offering.


   (G) Represents adjustments to record increased depreciation and
       amortization expense associated with the Kratz acquisition ($754,470 in
       cost of sales and $716,314 in operating expenses).


   (H) Represents an adjustment to record certain Kratz salaries at levels set
       forth in the purchase agreement.


   (I) Represents the incremental increase in interest expense from borrowings
       made to finance the Kratz acquisition.


   (J) Includes an adjustment of $1,681,605 to record tax provision for the
       pre-acquisition operations of Kratz as if it had been taxed as a C
       Corporation.


   (K) Includes $2,425,000 to remove the valuation allowance on deferred
       income taxes recorded by Whitehall during the year ended December 31,
       1997, since as a combined entity, the tax losses generated by Whitehall
       would have been offset by taxable income from AVS.

                         AGREEMENT AND PLAN OF MERGER


     THIS AGREEMENT AND PLAN OF MERGER is dated as of March 26, 1998 (the
"Agreement") by and among Aviation Sales Company, a Delaware corporation
("AVS"), WHC Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of AVS ("AVS Sub"), and Whitehall Corporation, a Delaware
corporation (the "Company").


     WHEREAS, the Board of Directors of each of AVS and the Company have
determined that a business combination between AVS and the Company merging
their respective businesses is in the best interests of their respective
companies and stockholders and accordingly have agreed to effect the merger
provided for herein upon the terms and subject to the conditions set forth
herein; and


     WHEREAS, it is the intention of the parties to this Agreement that (a) for
federal income tax purposes, the merger provided for herein shall qualify as a
"reorganization" within the meaning of Section 368 of the Internal Revenue Code
of 1986, as amended (the "Code"); and (b) for accounting purposes, the merger
provided for herein shall qualify as a "pooling of interests"; and


     NOW, THEREFORE, in consideration of the premises and of the
representations, warranties, covenants and agreements set forth herein, the
parties hereto hereby agree as follows:



                                   ARTICLE I

                                  THE MERGER

Agreement, at the Effective Time (as defined in Section 1.3 of this Agreement),
AVS Sub shall be merged with and into the Company in accordance with the laws
of the State of Delaware and the terms of this Agreement (the "Merger"),
whereupon the separate corporate existence of AVS Sub shall cease, and the
Company shall be the surviving corporation of the Merger (the Company, as the
surviving corporation after the Merger is sometimes referred to herein as the
"Surviving Corporation").


     1.2 CLOSING. Subject to the terms and conditions of this Agreement, the
closing of the Merger (the "Closing") shall take place (a) at the offices of

conditions set forth in Article VI of this Agreement (other than (i) those that
are waived by the party or parties for whose benefit such conditions exist, and
(ii) any such conditions which, by their terms, are not capable of being
satisfied until the Closing Date) are satisfied; or (b) at such other place,
time, and/or date as the parties hereto may otherwise agree. The date upon
which the Closing shall occur is referred to herein as the "Closing Date."


     1.3 EFFECTIVE TIME. If all the conditions to the Merger set forth in
Article VI of this Agreement have been fulfilled or waived and this Agreement
shall not have been terminated as provided in Article VII hereof, the parties
hereto shall cause a certificate of merger (the "Certificate of Merger") to be
properly executed and filed in accordance with the laws of the State of
Delaware and the terms of this Agreement on the Closing Date. The Merger shall
become effective at such time as the Certificate of Merger is duly filed with
the Secretary of State of Delaware or at such later time as is specified by the

     1.4 CONVERSION OF SHARES.


      (a) At the Effective Time, by virtue of the Merger and without any action
on the part of AVS, AVS Sub, the Company or the holders of the following
securities:


     (i) each share of Common Stock, par value $0.01 per share, of AVS Sub
   outstanding immediately prior to the Effective Time, shall be converted
   into one share of Common Stock, par value $0.01 per share, of the Surviving
   Corporation; and


     (ii) subject to Section 1.6(f), each share of Common Stock, $0.10 par
   value per share, of the Company (the "Company Common Stock") outstanding
   immediately prior to the Effective Time (except as otherwise provided in
   Section 1.4(c) hereof), shall be converted into the right to receive 0.5143
   of a validly issued, fully paid and nonassessable share of Common Stock,
   $.001 par value per share, of AVS ("AVS Common Stock") (the "Exchange
   Ratio").


      (b) Immediately following the Effective Time, all shares of Company
Common Stock shall cease to be outstanding and shall be canceled and retired
and shall cease to exist, and each holder of shares of Company Common Stock
shall thereafter cease to have any rights with respect to such shares of
Company Common Stock, except for the right to receive, without interest, the
consideration set forth in this Section 1.4 (and any dividends or other
distributions payable with respect thereto pursuant to Section 1.6(d)) and cash
in lieu of fractional shares of AVS Common Stock in accordance with Section 1.6
of this Agreement upon the surrender of a certificate representing such shares
of Company Common Stock in accordance with the provisions of this Article I.


      (c) Each share of Company Common Stock held by the Company as treasury
stock or owned by AVS or any Subsidiary (as defined in Section 1.4(d) of this
Agreement) of AVS immediately prior to the Effective Time shall be canceled,
and no payment shall be made with respect thereto.


      (d) For purposes of this Agreement, (i) the term "Average Closing Price"
shall mean the average of the per share last daily closing price of AVS Common
Stock as quoted on the New York Stock Exchange ("NYSE") (and as reported by The
Wall Street Journal or, if not reported thereby, by another authoritative
source) during the ten (10) consecutive trading days ending on and including
the last full trading day immediately preceding the Closing Date; (ii) the word
"Subsidiary" when used with respect to any Person means any corporation or
other organization, whether incorporated or unincorporated, of which (A) at
least fifty percent (50%) of the securities or other interests having by their
terms ordinary voting power to elect a majority of the board of directors or
others performing similar functions with respect to such corporation or other
organization is directly or indirectly owned or controlled by such Person or by
any one or more of its Subsidiaries; or (B) such Person or any other Subsidiary
of such Person is a general partner (excluding partnerships the general
partnership interests of which held by such Person or any Subsidiary of such
Person do not have a majority of the voting interests in such partnership), it
being understood that representations and warranties of a Person concerning any
former Subsidiary of such Person shall be deemed to relate only to the periods
during which such former Subsidiary was a Subsidiary of such Person; and (iii)
the word "Person" means an individual, a corporation, a limited liability
company, a partnership, an association, a trust or any other entity or
organization, including a government or political subdivision or any agency or
instrumentality thereof, or any affiliate (as that term is defined in the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder (the "Exchange Act")) of any of the foregoing.


     1.5 STOCK OPTIONS. All options to acquire Company Common Stock
(individually, a "Company Option" and collectively, the "Company Options")
outstanding at the Effective Time under the Company's 1992 Incentive Stock
Option Plan, the Company's 1992 Non-Employee Directors Stock Option Plan or
otherwise (the "Company Stock Option Plans") shall remain outstanding following
the Effective Time. At the Effective Time, such Company Options, by virtue of
the Merger and without any further action on the part of the Company or the
holder of such Company Options, shall be assumed by AVS in such manner that AVS
(a) is a corporation (or a parent or a subsidiary corporation of such


                                      A-2
<PAGE>

corporation) "assuming a stock option in a transaction to which Section 424(a)
applied" within the meaning of Section 424 of the Code; or (b) to the extent
that Section 424 of the Code does not apply to any such Company Options, would
be such a corporation (or a parent or a subsidiary corporation of such
corporation) were Section 424 applicable to such option. Each Company Option
assumed by AVS shall be exercisable upon the same terms and conditions as under
the applicable Company Stock Option Plan and the applicable option agreement
issued thereunder, except that (x) the unexercised portion of each such Company
Option shall be exercisable for that whole number of shares of AVS Common Stock
(rounded down to the nearest whole share) equal to the number of shares of
Company Common Stock subject to the unexercised portion of such Company Option
multiplied by the Exchange Ratio; and (y) the option exercise price per share
of AVS Common Stock shall be an amount equal to the option exercise price per
share of Company Common Stock subject to such Company Option in effect at the
Effective Time divided by the Exchange Ratio (the option price per share, as so
determined, being rounded up to the nearest full cent). No payment shall be
made for fractional interests. The term, exercisability, vesting schedule,
status as an "incentive stock option" under Section 422 of the Code, if
applicable, and all of the other terms of the Company Options shall otherwise
remain unchanged unless modified by or as a result of the transaction
contemplated by this Agreement (including, without limitation, to the extent
that all outstanding Company Options shall become vested and exercisable at the
Effective Time). As soon as practicable after the Effective Time, AVS shall
deliver to the holders of Company Options appropriate notices setting forth
such holders' rights pursuant to such Company Options, as amended by this
Section 1.5 as well as notice of AVS's assumption of the Company's obligations
with respect thereto (which occurs by virtue of this Agreement). AVS shall take
all corporate actions necessary to reserve for issuance such number of shares
of AVS Common Stock as will be necessary to satisfy exercises in full of all
Company Options after the Effective Time.


     1.6 EXCHANGE OF CERTIFICATES REPRESENTING COMPANY COMMON STOCK.


      (a) Continental Stock Transfer & Trust Company (or such other exchange
agent selected by AVS and reasonably acceptable to the Company) shall act as
exchange agent (the "Exchange Agent") in the Merger.


      (b) As of the Effective Time and in any event, no later than five (5)
business days after the Effective Time, AVS shall deposit or cause to be
deposited with the Exchange Agent for exchange in accordance with this Article
I, certificates representing the shares of AVS Common Stock issuable pursuant
to Section 1.4 in exchange for certificates formerly representing shares of
Company Common Stock outstanding immediately prior to the Effective Time and a
sufficient amount of cash to satisfy the cash payments to be made by AVS to
certain holders of Company Common Stock pursuant to Section 1.6(f) hereof.


      (c) Promptly after the Effective Time, AVS shall cause the Exchange Agent
to mail to each holder of a certificate or certificates which immediately prior
to the Effective Time represented outstanding shares of Company Common Stock
("Certificates") whose shares were converted into the right to receive AVS
Common Stock Common Stock pursuant to Section 1.4 (i) a notice of effectiveness
of the Merger, (ii) a letter of transmittal which shall specify that delivery
shall be effected, and risk of loss and title to such Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent; and (iii)
instructions for use in effecting the surrender of such Certificates in
exchange for the consideration to be received by such holder pursuant to
Sections 1.4 and 1.6 hereof. Upon surrender of a Certificate for cancellation
to the Exchange Agent, together with such letter of transmittal, duly executed
and completed in accordance with the instructions thereto, AVS shall cause to
be delivered to the person in whose name such Certificate shall have been
issued, or to such person as such person shall direct in writing in the letter
of transmittal, (A) a certificate representing that number of whole shares of
AVS Common Stock into which the shares previously represented by the surrender
of Certificates shall have been converted into the right to receive at the
Effective Time pursuant to Section 1.4; and (B) a check representing the amount
of cash in lieu of fractional shares, if any, and unpaid dividends and
distributions, if any, which such holder has the right to receive in respect of
the Certificate surrendered pursuant to the provisions of this Section 1.6, in
each case, after giving effect to any


                                      A-3
<PAGE>

required withholding tax, and the shares represented by the Certificate so
surrendered shall forthwith be canceled. No interest will be paid or accrued on
the cash in lieu of fractional shares and unpaid dividends and distributions,
if any, payable to holders of shares of Company Common Stock who receive shares
of AVS Common Stock pursuant to Section 1.4 hereof. In the event of a transfer
of ownership of Company Common Stock which is not registered in the transfer
records of the Company, the consideration to be paid to such holder of Company
Common Stock pursuant to Sections 1.4 and 1.6 hereof may be issued to such a
transferee if the Certificate representing such Company Common Stock is
presented to AVS, accompanied by all documents required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have
been paid or, alternatively, payments of such transfer tax to the Exchange
Agent. Until so surrendered, each Certificate that, at the Effective Time,
represented shares of Company Common Stock will be deemed from and after the
Effective Time, for all corporate purposes (except to the extent provided in
Section 1.6(d) below), to evidence the consideration to be received by the
holders of Company Common Stock pursuant to Sections 1.4 and 1.6 hereof.


      (d) Notwithstanding anything to the contrary contained herein, no
dividends or other distributions declared after the Effective Time on AVS
Common Stock shall be paid with respect to any shares of Company Common Stock
entitled to be converted into shares of AVS Common Stock represented by a
Certificate until such Certificate is surrendered for exchange as provided
herein. Subject to the effect of applicable laws, following surrender of any
such Certificate, there shall be paid to the holder of the certificates
representing whole shares of AVS Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time theretofore
payable with respect to such whole shares of AVS Common Stock and not paid,
less the amount of any withholding taxes which may be required thereon; and
(ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to
surrender and a payment date subsequent to surrender payable with respect to
such whole shares of AVS Common Stock, less the amount of any withholding taxes
which may be required thereon.


      (e) After the Effective Time, there shall be no transfers on the stock
transfer books of the Company of the shares of Company Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to AVS or the Surviving Corporation, they
shall be canceled and exchanged for the consideration set forth in this Article
I deliverable in respect thereof pursuant to this Agreement in accordance with
the procedures set forth in this Section 1.6. Certificates surrendered for
exchange by any person constituting an "affiliate" of the Company for purposes
of Rule 145(c) under the Securities Act of 1933, as amended (the "Securities
Act") shall not be exchanged until AVS has received an Affiliate Letter (as
defined herein) from such person as provided in Section 5.9.


      (f) No fractional shares of AVS Common Stock shall be issued upon
surrender for exchange of Certificates for Company Common Stock. In lieu of the
issuance of any fractional share of AVS Common Stock pursuant to Section 1.4,
cash adjustments will be paid to holders in respect of any fractional share of
AVS Common Stock that would otherwise be issuable, and the amount of such cash
adjustment shall be equal to such fractional proportion of the Average Closing
Price of a share of AVS Common Stock.


      (g) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Surviving Corporation, the posting by such person of a bond in such reasonable
amount as the Surviving Corporation may direct as indemnity against any claim
that may be made against it with respect to such Certificate, AVS will issue in
exchange for such lost, stolen or destroyed Certificate, the consideration to
be received by the holder of such Certificate pursuant to Sections 1.4 and 1.6
hereof.


      (h) Any portion of the property delivered to the Exchange Agent in
accordance with this Section 1.6(b) that remains unclaimed two years after the
Effective Time shall be delivered to AVS.


                                      A-4
<PAGE>

Any holder of a Certificate who has not theretofore surrendered such
Certificate for exchange pursuant to this Section 1.6 shall thereafter look
only to AVS for payment of the consideration deliverable in respect of such
Certificate determined pursuant to this Agreement, without any interest
thereon. Payment or delivery of any shares of AVS Common Stock, any cash in
lieu of fractional shares of AVS Common Stock and any dividends, or
distributions with respect to AVS Common Stock shall be subject to applicable
abandoned property, escheat and similar laws and none of AVS, AVS Sub, the
Company, the Surviving Corporation or any other person shall be liable to any
former holder of shares of Company Common Stock for any amount properly
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar laws.


     1.7 ADJUSTMENT OF EXCHANGE RATIO. In the event that, subsequent to the
date of this Agreement but prior to the Effective Time, the AVS Common Stock is
recapitalized or reclassified or AVS shall effect any stock split, reverse
stock split, stock dividend of AVS Common Stock, then the Exchange Ratio and
the Average Closing Price shall be appropriately and equitably adjusted to the
kind and amount of shares of stock and other securities and property which the
holders of such shares of AVS Common Stock would have been entitled to receive
had such shares been issued and outstanding as of the record date for
determining stockholders entitled to participate in such corporate event.


     1.8 TAX CONSEQUENCES AND ACCOUNTING TREATMENT. It is intended by the
parties hereto that the Merger shall constitute a reorganization within the
meaning of Section 368 of the Code and that the transaction be accounted for as
a pooling of interests.


     1.9 TAKING OF NECESSARY ACTION; FURTHER ACTION. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and AVS Sub, the officers and directors of the
Company and AVS Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action, so long as such action is consistent with this Agreement.

                                  ARTICLE III

               REPRESENTATIONS AND WARRANTIES OF AVS AND AVS SUB


     AVS and AVS Sub represent and warrant to the Company that the statements
contained in this Article III are true and correct, except as set forth in the
disclosure statement delivered by AVS and


                                      A-5
<PAGE>

AVS Sub to the Company concurrently herewith and identified as the "AVS
Disclosure Statement."All exceptions noted in the AVS Disclosure Statement
shall be numbered to correspond to the applicable sections to which such
exception refers; provided, however that for purposes of this Agreement and the
AVS Disclosure Statement any disclosure set forth on any particular schedule
shall be deemed disclosed in reference to all applicable schedules.


     3.1 EXISTENCE, GOOD STANDING, CORPORATE AUTHORITY. Each of AVS, AVS Sub
and each of the Subsidiaries of AVS other than AVS Sub (each such Subsidiary
singularly "AVS Subsidiary" or collectively "AVS Subsidiaries") (i) is a
corporation duly incorporated, validly existing and in good standing under the
laws of its respective jurisdiction of incorporation; (ii) has all requisite
power and authority to own or lease, and operate its properties and assets, and
to carry on its business as now conducted and as currently proposed to be
conducted, except where the failure to have such power and authority would not
have an AVS Material Adverse Effect (as defined herein) and to consummate the
transactions contemplated hereby; (iii) is duly qualified or licensed to do
business and is in good standing in all jurisdictions in which it owns or
leases property or in which the conduct of its business requires it to so
qualify or be licensed, except where the failure to so qualify, individually or
in the aggregate, would not have an AVS Material Adverse Effect; and (iv) has
obtained all licenses, permits, franchises and other governmental
authorizations necessary to the ownership or operation of its properties or the
conduct of its business, except where the failure to have obtained such
licenses, permits, franchises or authorizations would not have an AVS Material
Adverse Effect. The copies of AVS's and AVS Sub's Articles or Certificate of
Incorporation and By-Laws as in effect on the date hereof have been previously
delivered to the Company or have been made available for the Company's review
and are true and correct. For purposes of this Agreement, a "Material Adverse
Effect" when used with respect to any entity means (a) a material adverse
effect on the business, results of operations, financial condition or prospects
of such entity and its subsidiaries, taken as a whole, or (b) a material
impairment in the ability of such entity or its subsidiaries to perform any of
their obligations under this Agreement or to consummate the Merger.


     3.2 AUTHORIZATION OF AGREEMENT AND OTHER DOCUMENTS. The execution and
delivery of this Agreement and the other documents executed or to be executed
in connection herewith to which AVS or AVS Sub is a party (collectively, the
"AVS Ancillary Documents"), have been duly authorized by the Board of Directors
of AVS and AVS Sub and no other proceedings on the part of AVS or AVS Sub are
necessary to authorize the execution, delivery or performance of this Agreement
or any AVS Ancillary Document, except the approval of the Merger by the
stockholders of AVS. This Agreement is, and, as of the Closing Date, each of
the AVS Ancillary Documents will be, a valid and binding obligation of AVS
and/or AVS Sub, as the case may be, enforceable against AVS and/or AVS Sub, as
the case may be, in accordance with its terms, except to the extent that
enforcement thereof may be limited by bankruptcy, insolvency; reorganization,
moratorium, fraudulent conveyance or other similar laws affecting enforcement
of creditors' rights generally, and by general principles of equity (regardless
of whether enforcement is considered in a proceeding at law or in equity) and
subject to receipt of approval of the Merger by the AVS stockholders.


     3.3 NO VIOLATION. Neither the execution and delivery by AVS and AVS Sub of
this Agreement or the AVS Ancillary Agreements, nor the consummation by AVS and
AVS Sub of the transactions contemplated hereby and thereby in accordance with
their respective terms, will (a) assuming approval of the Merger by the
stockholders of AVS, conflict with or result in a breach of any provisions of
the Articles or Certificate of Incorporation or By-Laws of AVS or AVS Sub; (b)
result in a breach or violation of, a default under, or the triggering of any
payment or other material obligations pursuant to, or accelerate vesting under,
any of the AVS stock option plans, or any grant or award made under any of the
foregoing; (c) subject to obtaining the consents set forth in the AVS
Disclosure Statement, violate, conflict with, result in a breach of any
provision of, constitute a default (or an event which, with notice or lapse of
time or both, would constitute a default) under, result in the termination, or
in a right of termination or cancellation of, accelerate the performance
required by, result in the triggering of any payment or other material
obligations pursuant to, result in the creation of any lien, security interest,
charge or encumbrance upon any of the material properties of AVS, AVS Sub or
any of the AVS


                                      A-6
<PAGE>

Subsidiaries, other than as disclosed in the AVS Disclosure Statement, under,
or result in being declared void, voidable, or without further binding effect,
any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, deed of trust or any material license, franchise, permit, lease,
contract, agreement or other instrument, commitment or obligation to which AVS,
AVS Sub or any of the AVS Subsidiaries is a party, or by which AVS, AVS Sub or
any of the AVS Subsidiaries or any of their respective properties is bound or
affected, except for any of the foregoing matters which would not have an AVS
Material Adverse Effect; (d) assuming the Merger is so approved by stockholders
of AVS and assuming all required consents and approvals are obtained and all
applicable filings are made, contravene or conflict with or constitute a
violation of any provision of any law, regulation, judgement, injunction, order
or decree binding upon or applicable to AVS or AVS Sub, except for any of the
foregoing matters which would not have an AVS Material Adverse Effect; or (e)
other than the filings provided for in Sections 1.3 and 5.7, filings required
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"),
the Exchange Act, the Securities Act, or applicable state securities and "Blue
Sky" laws or filings in connection with the maintenance of qualification to do
business in other jurisdictions (collectively, the "Regulatory Filings"),
require any material consent, approval or authorization of, or declaration of,
or filing or registration with, any domestic governmental or regulatory
authority, the failure to obtain or make which would have an AVS Material
Adverse Effect.


     3.4 SEC DOCUMENTS. AVS has delivered or made available to the Company each
registration statement, report, proxy statement or information statement (as
defined in Regulation 14C under the Exchange Act) prepared by it since July 1,
1996, which reports constitute all of the documents (other than preliminary
material) required to be filed by AVS with the Securities and Exchange
Commission ("SEC") since such date, each in the form (including exhibits and
any amendments thereto) filed with the SEC (collectively, the "AVS Reports").
As of their respective dates, each of the AVS Reports complied and, in the case
of filings after the date hereof, will comply as to form in all material
respects with the applicable requirements of the Securities Act or the Exchange
Act, as the case may be, and the rules and regulations thereunder. None of the
AVS Reports contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements made therein, in the light of the circumstances under which they
were made, not misleading. AVS has filed with the SEC all reports required to
be filed under Sections 13, 14 and 15(d) of the Exchange Act since July 1,
1996. Each of the consolidated balance sheets of AVS included in or
incorporated by reference into the AVS Reports (including the related notes and
schedules) fairly present in all material respects the consolidated financial
position of AVS and the AVS Subsidiaries as of its date (subject, in the case
of unaudited statements, to normal year-end audit adjustments which would not
be material in amount or effect), and each of the consolidated statements of
income, retained earnings and cash flows of AVS included in or incorporated by
reference into the AVS Reports (including any related notes and schedules)
fairly present in all material respects the results of operations, retained
earnings or cash flows, as the case may be, of AVS and the AVS Subsidiaries for
the periods set forth therein (subject, in the case of unaudited statements, to
normal year-end audit adjustments which would not be material in amount or
effect). Except as and to the extent reflected or reserved against in the
financial statements included in the AVS's Quarterly Report on Form 10-Q for
the quarter ended September 30, 1997 (the "AVS Form 10-Q") or as disclosed
herein or in the AVS Disclosure Statement, neither AVS nor any of the AVS
Subsidiaries had as of such date any liability or obligation of any kind,
whether accrued, absolute, contingent, unliquidated or other and whether due or
to become due (including any liability for breach of contract, breach of
warranty, torts, infringements, claims or lawsuits), which was material to the
business, assets, results of operations or financial conditions of AVS and the
AVS Subsidiaries taken as a whole. Except as set forth in the AVS Disclosure
Statement, since September 30, 1997, neither AVS nor any of the AVS
Subsidiaries has incurred any liability or obligation of any kind which, in any
case or in the aggregate, is material to the business, assets, results of
operations or financial condition of AVS and the AVS Subsidiaries taken as a
whole, except in the ordinary course of business. There are no extraordinary or
material non-recurring items of income or expense during the periods covered by
such financial statements and the consolidated balance sheets of the AVS
included or incorporated therein do not reflect any write-up or


                                      A-7
<PAGE>

revaluation increasing the book value of any assets, except as specifically
disclosed in the notes thereto. The financial statements of AVS, including the
notes thereto, included in or incorporated by reference into the AVS Reports
comply as to form in all material respects with the published rules and
regulations of the SEC with respect thereto, and have been prepared in
accordance with generally accepted accounting principles consistently applied
("GAAP") (except as may be indicated in the notes thereto). Since January 1,
1993, there has been no change in AVS's accounting methods or principles that
would be required to be disclosed in AVS financial statements in accordance
with GAAP, except as described in the notes to such AVS financial statements.


     3.5 NO UNDISCLOSED LIABILITIES. There are no liabilities or obligations of
any nature (whether accrued, absolute or contingent) of AVS or the AVS
Subsidiaries other than (i) liabilities disclosed or provided for in the most
recent financial statements contained in the AVS Reports; (ii) liabilities
which, individually or in the aggregate, are not material to AVS or the AVS
Subsidiaries; (iii) liabilities under this Agreement (or contemplated hereby)
or disclosed in the AVS Disclosure Statement and (iv) liabilities incurred
since September 30, 1997 in the ordinary course of business and consistent with
past practices.


     3.6 NO BROKERS. AVS has not entered into any contract, arrangement or
understanding with any person or firm which may result in the obligation of the
Company or AVS, AVS Sub or their respective Subsidiaries to pay any finder's
fee, brokerage or agent's commissions or other like payments in connection with
the negotiations leading to this Agreement or the consummation of the
transactions contemplated hereby; provided, however that AVS has retained SBC
Warburg Dillon Read, Inc. ("SBCWDR") to render an opinion with respect to the
fairness of the Merger transaction from the standpoint of AVS's stockholders
and has agreed to pay a fee to them for providing such services.


     3.7 OPINION OF FINANCIAL ADVISOR. AVS has received the opinion of SBCWDR,
to the effect that, as of the date of such opinion, the consideration to be
paid by AVS pursuant to the Merger is fair to AVS and its stockholders from a
financial point of view.


     3.8 AVS COMMON STOCK. Subject to obtaining the approval of the
stockholders of AVS, the issuance and delivery by AVS of shares of AVS Common
Stock in connection with the Merger and this Agreement have been duly and
validly authorized by all necessary corporate action on the part of AVS. The
shares of AVS Common Stock to be issued in connection with the Merger and this
Agreement, when issued in accordance with the terms of this Agreement, will be
validly issued, fully paid and nonassessable and free of preemptive rights.


     3.9 CAPITALIZATION


      (a) The total authorized capital stock of AVS consists of (i) 30,000,000
shares of AVS Common Stock, 9,586,871 shares of which are issued and
outstanding as of March 23, 1998, and (ii) 1,000,000 shares of Preferred Stock,
none of which are issued and outstanding as of the date of this Agreement. The
authorized capital stock of AVS Sub consists of 1,000 shares of Common Stock,
$0.01 par value per share, 100 shares of which, as of the date hereof, are
issued and outstanding and are held by AVS.


      (b) Except as set forth in the AVS Disclosure Statement, there are
currently no outstanding, and as of the Closing; there will be no outstanding
(i) securities convertible into or exchangeable for any capital stock of AVS or
any of the AVS Subsidiaries, (ii) options, warrants or other rights to purchase
or subscribe to capital stock of AVS or any of the AVS Subsidiaries or
securities convertible into or exchangeable for capital stock of AVS or any of
the AVS Subsidiaries, or (iii) contracts, commitments, agreements,
understandings, arrangements, calls or claims of any kind relating to the
issuance of any capital stock of AVS or any of the AVS Subsidiaries.


     3.10 MATERIAL ADVERSE CHANGE. Since September 30, 1997 to the date of this
Agreement, AVS, AVS Sub and the AVS Subsidiaries, taken as a whole, have not
suffered any change in their businesses, operations, assets, liabilities,
financial condition or prospects which would reasonably have an AVS


                                      A-8
<PAGE>

Material Adverse Effect; provided, that an AVS Material Adverse Effect will not
be deemed to have occurred solely as a result of fluctuations in the trading
price of the AVS Common Stock.

     3.11 DISCLOSURE DOCUMENTS. None of the information supplied or to be
supplied by AVS or any of its affiliates, directors, officers, employees,
agents or representatives, in writing specifically for inclusion or
incorporation by reference in, and which is included or incorporated by
reference in, (i) the Form S-4 (as defined in Section 5.7 of this Agreement) or
any amendment or supplement thereto, (ii) the proxy statement to be mailed to
Company's stockholders (the "Company Proxy Statement") in connection with the
meeting of Company's stockholders called to consider and vote upon the approval
of the Merger (the "Company Stockholder Meeting") or any amendment or
supplement thereto, or (iii) any other documents filed or to be filed by
Company with the Commission or any other Governmental Authority in connection
with the transactions contemplated hereby, will, at the respective times such
documents are filed, and, in the case of the Form S-4 or any amendment or
supplement thereto, at the date of Company Stockholder Meeting, and, in the
case of the Company Proxy Statement or any amendment or supplement to either
thereof, at the time of mailing to Company stockholders or at the time of the
Company Stockholders Meeting, be false or misleading with respect to any
material fact, or omit to state any material fact necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading or necessary to correct any statement in any earlier
communication with respect to the solicitation of any proxy for the Company
Stockholder Meeting. The Form S-4 will comply as to form in all material
respects with the applicable provisions of the Securities Act and the rules and
regulations under such Act (except that no representation is made as to the
form of the Company Proxy Statement to be included as the prospectus therein).

     3.12 TAX REORGANIZATION; ACCOUNTING MATTERS. Neither AVS nor any of its
Subsidiaries has taken or failed to take any action which would prevent the
Merger from (a) constituting a reorganization within the meaning of section
368(a) of the Code; or (b) being treated as a "pooling or interests" in
accordance with Accounting Principles Board Opinion No. 16, the interpretative
releases issued pursuant thereto and the pronouncements of the SEC.

     3.13 COMPLIANCE WITH LAWS.

      (a) AVS, AVS Sub and each of the AVS Subsidiaries hold all permits,
licenses, variances, exemptions, orders, approvals, authorizations,
certificates, filings, franchises, notices and rights of all Governmental
Authorities necessary for each of them to own, lease or operate its properties
and assets and for the lawful conduct of its business (the "Permits"), except
where the failure to hold such Permits would not have an AVS Material Adverse
Effect. None of such Permits is or will be materially impaired by the execution
and delivery of this Agreement or the consummation of the transactions
contemplated hereby.

      (b) AVS, AVS Sub and each of the AVS Subsidiaries are in compliance with
the terms of its Permits in all material respects.

      (c) AVS, AVS Sub and each of the AVS Subsidiaries are in compliance with
all statutes, laws, ordinances orders, rules, or regulations of any
Governmental Authority (including, but not limited to, those related to
occupational health and safety, or employment and employment practices) that
are applicable to AVS, AVS Sub or any of the AVS Subsidiaries or affect or
relate to this Agreement or the transactions contemplated hereby, except for
any noncompliance that would not have an AVS Material Adverse Effect.

      (d) As of the date of this Agreement, and as of the Closing, no
investigation, review, inquiry or proceeding by any Governmental Authority with
respect to AVS, AVS Sub or any of the AVS Subsidiaries is to the knowledge of
the AVS, pending or threatened which, if determined unfavorably, would have an
AVS Material Adverse Effect.

      (e) Neither AVS nor AVS Sub nor any of the AVS Subsidiaries are subject
to any agreement, contract, judgment, order or decree with any Governmental
Authority arising out of any current or previously existing violations of any
laws, ordinances or regulations applicable to AVS, AVS Sub or any of the AVS
Subsidiaries.


                                      A-9
<PAGE>

      (f) For the purposes of this Agreement, "Governmental Authority" shall
mean any nation, or government, any state, regional, local or other political
subdivision thereof, and any entity or official exercising executive,
legislative, judicial, regulatory, or administrative functions or pertaining to
government.


     3.14 LITIGATION. Except as set forth in the AVS Reports filed with the SEC
prior to the date hereof or as set forth in the AVS Disclosure Statement, (i)
there is no litigation or proceeding including, without limitation, any
arbitration proceeding, in law or in equity, and there are no proceedings or
governmental investigations before any commission or other administrative
authority, pending or, to AVS's knowledge, threatened against AVS, AVS Sub or
any of the AVS Subsidiaries which, if adversely determined, is reasonably
likely to have, either individually or in the aggregate, an AVS Material
Adverse Effect; (ii) there is no judgment, decree, injunction, rule or order of
any court, governmental department, commission, agency, instrumentality or
arbitrator applicable to AVS, the AVS Sub or any of the AVS Subsidiaries
having, or which is reasonably likely to have, either individually or in the
aggregate, an AVS Material Adverse Effect; and (iii) to the knowledge of AVS,
there is no action, suit, proceeding or investigation pending or threatened
against AVS, the AVS Sub or any of the AVS Subsidiaries which seeks to
restrain, enjoin or delay the consummation of the Merger or any of the other
transactions contemplated hereby or which seeks damages in connection
therewith, and no injunction of any type referred to in Section 6.1(c) has been
entered or issued.


     3.15 TAXES.


      (a) As used in this Agreement, (i) the term "Taxes" means all federal,
state, local, foreign and other net income, gross income, gross receipts,
sales, use, ad valorem, transfer, franchise, profits, license, lease, service,
service use, withholding, payroll, employment, excise, severance, stamp,
occupation, premium, property, windfall profits, customs, duties or other
taxes, fees, assessments or charges of any kind whatever of a nature similar to
taxes, together with any interest and any penalties, additions to tax or
additional amounts with respect thereto, and the term "Tax" means any one of
the foregoing Taxes; and (ii) the term "Returns" means all returns,
declarations, reports, statements and other documents required to be filed in
respect of Taxes, and the term "Return" means any one of the foregoing Returns.
 


      (b) There have been properly completed and filed on a timely basis and in
correct form all material Returns required to be filed by AVS or any of the AVS
Subsidiaries. As of the time of filing, the foregoing Returns were correct and
complete in all material respects. Except as set forth in the AVS Disclosure
Statement, an extension of time within which to file any Return which has not
been filed has not been requested or granted.


      (c) With respect to all amounts in respect of Taxes imposed upon AVS or
any of the AVS Subsidiaries, or for which AVS or any of the AVS Subsidiaries is
or could be liable, whether to taxing authorities (as, for example, under law)
or to other persons or entities (as, for example, under tax allocation
agreements), with respect to all taxable periods or portions of periods ending
on or before September 30, 1997, (i) all applicable tax laws and agreements
have been complied with in all material respects, and (ii) all amounts required
to be paid by AVS or the AVS Subsidiaries, to taxing authorities or others, on
or before the date hereof have been paid or adequately reserved for on the
financial statements contained in the AVS Reports, and any Taxes accrued but
not due and payable as of September 30, 1997 have been accrued or otherwise
reserved for in financial statements contained in the most recent AVS Report.
No Taxes have been (or will prior to the Closing Date be) recorded by AVS or
any of the AVS Subsidiaries other than in the ordinary course of business.
There are no Liens filed against any asset of the Company or any of its
Subsidiaries resulting from the failure to pay any Tax when due.


      (d) No material issues have been raised (and are currently pending) by
any taxing authority in connection with any of the Returns. No waivers of
statutes of limitation with respect to the Returns have been given by AVS or
any of the AVS Subsidiaries (or with respect to any Return which a taxing
authority has asserted should have been filed by AVS or any of the AVS
Subsidiaries) which waivers are


                                      A-10
<PAGE>

still in effect. The AVS Disclosure Statement sets forth for the past seven
years, the years for which examinations or audits of Florida state sales tax
and federal income tax returns have been completed, those years for which
examinations are presently being conducted, and those years for which such
returns will be required but are not yet due to be filed and have not yet been
filed. All deficiencies asserted or assessments made as a result of any
examinations have been fully paid, or are fully reflected as a liability in the
financial statements contained in the AVS Report, or are being contested and an
adequate reserve therefor has been established and is fully reflected as a
liability in the financial statements contained in the most recent AVS Report.


      (e) The unpaid Taxes of AVS or any of the AVS Subsidiaries do not
materially exceed the reserve for tax liability (excluding any reserve for
deferred Taxes established to reflect timing differences between book and tax
income) set forth or included in the financial statements included in the most
recent AVS Report, as adjusted for the passage of time through the Closing.


      (f) Neither AVS nor any of the AVS Subsidiaries is or at any time has
been a party to or bound by (nor will AVS or any of the AVS Subsidiaries become
a party to or bound by) any tax indemnity, tax sharing or tax allocation
agreement.


      (g) All material elections with respect to Taxes affecting AVS or any of
the AVS Subsidiaries that are currently effective as of the date hereof that
are not reflected in the AVS's Returns are set forth in the AVS Disclosure
Statement.


      (h) There are no challenges on appeals pending regarding the amount of
Taxes on, or the addressed valuation of, the real estate owned or leased by AVS
or any of the AVS Subsidiaries, and no special arrangements or agreements exist
with any governmental authority with respect thereto (the representations and

Subsidiaries with respect to the quality of or absence of defects in such
products or services nor are there any facts known to the Company relating to
the quality of or absence of defects in such products or services which, if
known by a potential claimant or governmental authority, would reasonably give
rise to a material claim or proceeding. The Company's warranty policy is
generally described in the Disclosure Statement. The Company has no knowledge
of or reason to believe that the percentage of warranty claims for products
sold or services rendered by the Company and its Subsidiaries prior to the
Closing Date will exceed historical levels.


     4.17 PRODUCTS LIABILITY. Neither the Company nor any of its Subsidiaries
have received any written notice relating to, nor does the Company have

authorities (as, for example, under law) or to other persons or entities (as,

periods or portions of periods ending on or before September 30, 1997, (i) all
applicable tax laws and agreements have been complied with in all material

assessments made as a result of any examinations have been fully paid, or are
fully reflected as a liability in the financial statements contained in the
Company Report, or are being contested and an adequate reserve therefor has
been established and is fully reflected as a liability in the financial
statements contained in the most recent Company Report.


      (d) The unpaid Taxes of the Company or any of its Subsidiaries do not
materially exceed the reserve for tax liability (excluding any reserve for
deferred Taxes established to reflect timing differences between book and tax
income) set forth or included in the financial statements included in the most
recent Company Report, as adjusted for the passage of time through the Closing.
 


      (e) Neither the Company nor any of its Subsidiaries is or at any time has

Taxes on, or the addressed valuation of, the Real Estate or the Leased

general increase in real estate taxes.)


      (h) There is no assessment for Taxes (in addition to the normal, annual
general real estate tax assessment) pending against the Company, or to the
Company's knowledge, threatened with respect to any portion of the Real Estate
or, to the extent the Company or its Subsidiaries is liable for payment of the
Leased Premises.

be qualified, except where the failure to be so qualified would not have a
Joint Venture Material Adverse Effect.


      (b) The Joint Venture Agreement made and entered into as of January 5,
1994 by and among Aero Hushkit Corporation, a Delaware corporation ("AHC"), WDW
Aviation Management, Inc., a Delaware corporation and Avro Corp, a California
corporation (the "Joint Venture Agreement"), has been duly executed and

applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and general equitable
principles regardless of whether such enforceability is considered in a
proceeding at law or in equity.


      (c) The record owners of all the outstanding partnership interests of the
Joint Venture are set forth in the Joint Venture Agreement and the partnership
interest of AHC in the Joint Venture is free of all Liens, other than Permitted
Encumbrances.


      (d) To the Company's knowledge the execution and delivery of this

organizational documents of the Joint Venture, (ii) violate or conflict with
any law, statute, ordinance, rule, regulation, decree, writ, injunction,
judgment or order of any Governmental Authority or of any arbitration award
which is either applicable to, binding upon or enforceable against the Joint
Venture, (iii) conflict with, result in any breach of, or constitute a default
(or an event which would, with the passage of time or the giving of notice or
both, constitute a default) under, or give rise to a right to terminate, amend,
modify, abandon or accelerate, any material contract which is applicable to,
binding upon or enforceable against the Joint Venture, (iv) result in or
require the creation or imposition of any Lien upon or with respect to any of
the property, assets or the issued and outstanding interests of the Joint
Venture, or give rise to a right to buy the partnership interest of AHC in the
Joint Venture, or (v) require the consent, approval, authorization or permit

otherwise, except (i) to the extent reflected or taken into account in its
Financial Statements and not heretofore paid or discharged, (ii) liabilities
incurred in the ordinary course of business consistent with past practice since
the date of its Interim Statements (none of which relates to breach of
contract, breach of warranty, tort, infringement or violation of law, or which
arose out of any action, suit, claim, governmental investigation or arbitration
proceeding), (iii) normal accruals, reclassifications, and audit adjustments
which would be reflected on an audited financial statement and (iv) liabilities
incurred in the ordinary course of business.


      (i) To the Company's knowledge, there is no action, suit or other legal
or administrative proceeding or governmental investigation pending, or to the
best knowledge of the Company, threatened, by or against the Joint Venture or

Adverse Effect or which questions the validity or enforceability of the Joint
Venture Agreement. To the Company's knowledge, there are no outstanding orders
or decrees issued by any Governmental Authority in any proceeding to which the
Joint Venture is or was a party which have not been complied with in full.


     4.26 INAPPROPRIATE PAYMENTS. Neither the Company, its Subsidiaries nor, to
the Company's knowledge, any of their respective officers, directors, principal
stockholders, employees, agents or representatives has made, directly or
indirectly, with respect to the Company, its Subsidiaries or their respective
business activities, any bribes or kickbacks, illegal political contributions,
payments from corporate funds not recorded on the books and records of the
Company or its Subsidiaries, payments from corporate funds to governmental
officials, in their individual capacities, for the purpose of affecting their
action or the action of the government they represent, to obtain favorable
treatment in securing business or licenses or to obtain special concessions, or
illegal payments from corporate funds to obtain or retain business.


     4.27 ABSENCE OF INDEMNIFIABLE CLAIMS, ETC. There are no pending claims
and, to the knowledge of the Company, no facts that would reasonably entitle
any director, officer or employee of the Company or its Subsidiaries to
indemnification by the Company or its Subsidiaries under applicable law, the
Certificate of Incorporation or By-laws of the Company or its Subsidiaries or
any insurance policy maintained by the Company or its Subsidiaries.

which may result in the obligation of the Company or AVS, AVS Sub or their
respective Subsidiaries to pay any finder's fee, brokerage or agent's
commissions or other like payments in connection with negotiations leading to
this Agreement or the consummation of the transactions contemplated hereby
provided, however, that the Company has retained Ladenburg, Thalmann & Co.,
Inc. ("Ladenburg") to render an opinion with respect to the fairness of the
consideration to be received by the Company's stockholders in the Merger and
has agreed to pay a fee to Ladenburg.


     4.30 TAX REORGANIZATION AND POOLING OF INTEREST ACCOUNTING TREATMENT.
Neither the Company nor any of its Subsidiaries has taken or failed to take any
action which would prevent the Merger from (a) constituting a reorganization
within the meaning of section 368(a) of the Code or (b) being treated as a
"pooling or interests" in accordance with Accounting Principles Board Opinion
No. 16, the interpretative releases issued pursuant thereto, and the
pronouncements of the SEC.


     4.31 OPINION OF FINANCIAL ADVISOR. The Company has been orally advised by
Ladenburg to the effect that, as of the date hereof, the consideration to be
received by the stockholders of the Company pursuant to the Merger is fair to
such stockholders from a financial point of view.

Stockholder Meeting and at the Effective Time, and, in the case of the Company
Proxy Statement or any amendment or supplement to either thereof, at the time
of mailing of the Company Proxy Statement to Company's stockholders or at the
time of the Company Stockholders Meeting or any other meeting of the Company's
stockholders to be held in connection with the Merger, and, in the case of the
AVS Proxy Statement or any amendment or supplement thereto, at the time of the
AVS Stockholder Meeting, be false or misleading with respect to any material
fact, or omit to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading or necessary to correct any statement in any earlier
communication. The Form S-4 (to the extent that the Company Proxy Statement

                                   COVENANTS


     5.1 ALTERNATIVE PROPOSALS.


      (a) Prior to the Effective Time, the Company agrees that neither it nor
any of its Subsidiaries shall, and it shall direct and cause its officers,
directors, employees, agents and representatives (including, without
limitation, any investment banker, attorney or accountant retained by it or any
of the Subsidiaries) not to, (i) initiate or solicit, directly or indirectly,
any inquiries or the making or implementation of any proposal or offer
(including, without limitation, any proposal or offer to the stockholders of
the Company) with respect to a merger, acquisition, consolidation or similar
transaction involving, or any purchase of all or any significant portion of the
assets or any equity securities of, the Company or its Subsidiaries (any such
proposal or offer being hereinafter referred to as an "Alternative Proposal"),
(ii) engage in any negotiations concerning, or provide any confidential
information or data to, or have any discussions with, any person relating to an
Alternative Proposal, or otherwise facilitate any effort or attempt to make or
implement an Alternative Proposal, or (iii) subject to subsection (b) of this
Section 5.1, enter into any agreement or understanding with any Person other
than AVS with the intent to effect any Alternative Proposal; provided that
nothing contained in this Section 5.1 shall prohibit the Company or the Board
of Directors of the Company (the "Company Board"), to the extent required by
their fiduciary duties under applicable law, from providing information to, or
participating in discussions with, any party that makes an unsolicited inquiry
with respect to the Company if the Company Board reasonably believes such party
may propose an Alternative Proposal on terms that are superior, from a
financial point of view, to the terms of the Merger for the stockholders of the
Company. The Company will immediately give written notice to AVS of its receipt
of any Alternative Proposal or inquiry with respect to making an Alternative
Proposal. Nothing contained herein shall be construed to prohibit the Company
or the Company Board from making any disclosure to its stockholders which, in
the judgment of the Company Board as advised by counsel, may be required by
applicable law in connection with any such proposal or offer.


      (b) Except as set forth in this Section 5.1, the Company Board shall not
approve or recommend, or cause the Company to enter into any agreement with
respect to, any Alternative Proposal. Notwithstanding the foregoing, if the
Company Board, after consultation with and based upon the advice of independent
legal counsel, determines in good faith that it is necessary to do so in order
to comply with its fiduciary duties to stockholders under applicable law, the
Company Board may approve or recommend a Superior Proposal (as defined below)
or cause the Company to enter into an agreement with respect to, a Superior
Proposal, but in each case only after providing prompt written notice to AVS
advising that the Company Board has determined to approve or recommend, or
authorize the Company to enter into an agreement with respect to, a Superior
Proposal. For purposes of this Agreement, a "Superior Proposal" means an
Alternative Proposal on terms which the Company Board determines in its good
faith judgment to be more favorable to the Company's stockholders than the
Merger.

rules and regulations promulgated under the Securities Act. The Company shall
deliver or cause to be delivered to AVS,


                                      A-33
<PAGE>

Letters.

From and after the date hereof and until the Effective Time, neither AVS nor

(a) knowingly take any action, or knowingly fail to take any action, that would
jeopardize qualification of the Merger as (i) a reorganization within the
meaning of Section 368(a) of the Code; or (ii) a "pooling of interests" for
accounting purposes; or (b) enter into any contract, agreement, commitment or
arrangement with respect to the foregoing. After the Effective Time, AVS shall
not take or fail to take (and shall cause the Surviving Corporation not to take
or fail to take) any action that is reasonably likely to jeopardize

368(a) of the Code.


     5.12 EMPLOYEE BENEFIT PLANS. AVS covenants and agrees that it will
continue the Company's existing benefit plans and arrangements for a period of
up to three (3) months following the Effective Date. Thereafter, to the extent
the existing benefit plans and arrangements provided by the Company to its
employees are terminated, such employees who remain employees of the Surviving
Corporation or AVS or any of its Subsidiaries shall be entitled to participate
in all benefit plans and arrangements that are available and subsequently
become available to AVS's employees on the same basis as AVS's employees in
similar positions are eligible to participate. For purposes of satisfying the
terms and conditions of such plans, AVS shall give full credit for eligibility,
vesting or benefit accrual for each participant's period of service with the
Company prior to the Effective Time. To the extent AVS's benefit plans provide
medical or dental welfare benefits after the Closing Date, AVS shall cause all
pre-existing condition exclusions and actively at work requirements to be
waived and AVS shall provide that any expenses incurred on or before the
Closing Date shall be taken into account under AVS's benefit plans for purposes
of satisfying the applicable deductible, coinsurance and maximum out-of-pocket
provisions for such employees and their covered dependents.


     5.13 COMPANY OPTIONS. Immediately after the Effective Time, but in any
event, no later than 5 days after the Closing Date, AVS shall register the

     5.14 INDEMNIFICATION OF DIRECTORS AND OFFICERS.


      (a) Until six years from the Effective Time, unless otherwise required by
Law, the certificate of incorporation and by-laws of the Surviving Corporation
shall contain provisions no less favorable with respect to the elimination of
liability of directors and the indemnification of (and advancement of expenses
to) directors, officers, employees and agents that are set forth in the
certificate of incorporation and by-laws of the Company, as in effect on the
date hereof.


      (b) From and after the Effective Time, AVS and the Surviving Corporation
shall, jointly and severally, indemnify, defend and hold harmless each person
who is now, or has been at any time prior to the date of this Agreement or who
becomes prior to the Effective Time, an officer, director, employee


                                      A-34
<PAGE>

or agent of the Company or any of its Subsidiaries (collectively, the
"Indemnified Parties") against all losses, reasonable expenses (including
reasonable attorneys' fees), claims, damages, liabilities or amounts that are
paid in settlement of, or otherwise in connection with, any threatened or
actual claim, action, suit, proceeding or investigation (a "Claim"), based in
whole or in part on or arising in whole or in part out of the fact that the
Indemnified Party (or the person controlled by the Indemnified Party) is or was
a director, officer, employee or agent of the Company or any of its
Subsidiaries and pertaining to any matter existing or arising out of actions or
omissions occurring at or prior to the Effective Time including, without
limitation, any Claim arising out of this Agreement or any of the transactions
contemplated hereby), whether asserted or claimed prior to, at or after the
Effective Time, in each case to the fullest extent permitted under Delaware
law, and shall pay any expenses, as incurred, in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
fullest extent permitted under Delaware law. Without limiting the foregoing, in
the event any such Claim is brought against any of the Indemnified Parties, (i)
such Indemnified Parties may retain counsel (including local counsel)
satisfactory to them and which shall be reasonably satisfactory to AVS and the
Surviving Corporation and AVS and the Surviving Corporation shall pay, jointly
and severally, all reasonable fees and expenses of such counsel for such
Indemnified Parties; and (ii) AVS and the Surviving Corporation shall use all
reasonable efforts to assist in the defense of any such Claim, provided that
AVS and the Surviving Corporation shall not be liable for any settlement
effected without their written consent, which consent, however, shall not be
unreasonably withheld. Notwithstanding the foregoing, nothing contained in this
Section 5.14 shall be deemed to grant any right to any Indemnified Party which
is not permitted to be granted to an officer, director, employee or agent of
the Company under Delaware law, assuming for such purposes that the Company's
certificate of incorporation and by-laws provide for the maximum
indemnification permitted by law.


     5.15 PUBLICATION OF POST-MERGER RESULTS. AVS shall use its reasonable best

other party or any of such other party's officers, employees or authorized
representatives pursuant to this Agreement (unless such information is or
becomes publicly available or readily ascertainable from public or published
information or trade sources through no wrongful act of such first party) and
(ii) use all such data and information solely for the purpose of consummating
the transactions contemplated hereby, except, in either case, as may be
otherwise required by law or legal process or as may be necessary or
appropriate in connection with the enforcement of, or any litigation
concerning, this Agreement. In the event this Agreement is terminated, each
party shall promptly return, if so requested by any other party, all nonpublic
documents obtained from such other party in connection with the transactions
contemplated hereby and any copies thereof which may have been made by such
first party and shall use its reasonable efforts to cause its officers,
employees and authorized representatives to whom such documents were furnished
promptly to return such documents and any copies thereof any of them may have
made.


     5.19 DEFENSE OF LITIGATION. Each of the parties agrees to vigorously
defend against all actions, suits or proceedings in which such party is named
as a defendant which seek to enjoin, restrain or prohibit the transactions
contemplated hereby or seek damages with respect to such transactions. No


                                      A-35
<PAGE>

party shall settle any such action, suit or proceeding or fail to perfect on a
timely basis any right to appeal any judgment rendered or order entered against
such party therein without the consent of the other party (which consent shall
not be withheld unreasonably). Each of the parties further agrees to use its
reasonable efforts to cause each of its affiliates, directors and officers to
vigorously defend any action, suit or proceeding in which such affiliate,
director or officer is named as a defendant and which seeks any such relief to
comply with this Section to the same extent as if such person were a party
hereto.


     5.20 ACTIONS BY AVS SUB. In its capacity as sole stockholder of AVS Sub,

corporate action necessary on its part to consummate the Merger and the

acquisition" or other form of anti-takeover statute or regulation shall become
applicable to the transactions contemplated hereby, each of the Company, AVS
and AVS Sub and their respective members of their Boards of Directors shall
grant such approvals to take such actions as are necessary to that the
transactions contemplated by this Agreement may be consummated as promptly as
practicable on the terms contemplated herein and otherwise act to eliminate or
minimize the effects of such statute or regulation on the transactions
contemplated herein.


     5.22 NYSE LISTING. AVS agrees to use its reasonable efforts to cause the

terminated and the Merger may be abandoned by action of either the Company
Board or Board of Directors of AVS if (a) the Merger shall not have been
consummated by September 30, 1998; provided, however, that the right to

party has caused (directly or indirectly) or aided in the failure to obtain

caused or aided in the failure to obtain such approval if the Company Board
withdraws its recommendation to the Company's stockholders in accordance with
Section 5.3 by accepting or recommending a Superior Proposal; or (c) a court of
competent jurisdiction or a governmental, regulatory or administrative agency
or commission shall have issued an order, decree or ruling or taken any other

contained in this Agreement which would have an AVS Material Adverse Effect; or
(b) there has been a material breach of any of the material covenants or
agreements set forth in this Agreement on the part of AVS, which breach is not

     7.5 EFFECT OF TERMINATION AND ABANDONMENT.


      (a) In the event that this Agreement is terminated by AVS pursuant to
Section 7.4(a) and the Company enters into an agreement or an understanding
with respect to a Superior Proposal within one year of the date of such
termination, then the Company shall immediately pay AVS a fee in an amount
equal to $7,500,000. Additionally, if the Company terminates this Agreement
pursuant to Section 7.3 or if AVS terminates this Agreement pursuant to Section
7.4(b) or 7.4(c), the breaching party shall reimburse the non-breaching party
for all actual out-of-pocket costs and expenses incurred by the non-breaching
party in connection with this Agreement and the consummation and negotiation of
the transactions contemplated hereby, including, without limitation, legal,
professional and service fees and expenses, including fees relating to the
delivery of the fairness opinion provided, however, that the aggregate
reimbursement amount of all such costs and expenses shall not exceed $500,000.
All such amounts which may become due shall be payable pursuant to this Section
7.5 shall be paid by wire transfer of same day funds on the date on which the
Agreement is terminated or, if termination occurs under Section 7.4(a), upon
the date on which the Company enters into an agreement with respect to a
Superior Proposal. The parties acknowledge that the agreements contained in
this Section 7.5(a) are an integral part of the transactions contemplated by
this Agreement, and that, without these agreements, the other party would not
enter into this Agreement. Accordingly, if either party fails to promptly pay
the amounts due pursuant to this Section 7.5(a), and, in order to obtain such
payment, the other party commences a suit which results in a final,
non-appealable judgment against the other party for the amounts set forth in
this Section 7.5(a), the breaching party shall pay to the non-breaching party
its costs and expenses (including attorneys' fees) incurred in connection with
such suit, together with interest on the amount of the fee at the rate of 12%
per annum.


      (b) In the event of termination of this Agreement and the abandonment of
the Merger pursuant to this Article 7, all obligations of the parties hereto
shall terminate, except the obligations of the parties pursuant to this Section
7.5 and the provisions of Sections 5.10 and 5.18, which obligations shall
survive the termination of this Agreement.


     7.6 EXTENSION; WAIVER. At any time prior to the Effective Time, any party
hereto, by action taken by its Board of Directors, may, to the extent legally
allowed, (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto; (b) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto; and (c) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall
be valid only if set forth in an instrument in writing signed on behalf of such
party.

March 26, 1998



Board of Directors
Aviation Sales Company
6905 NW 25th Street
Miami, FL 33122-1898



Gentleman:


     We understand that Aviation Sales Company, a Delaware corporation
("Aviation Sales" or the "Company"), is considering a transaction (the
"Merger") whereby as a result of the issuance of shares of common stock, par
value $0.10 per share, of the Company ("Aviation Sales Common Stock") to
holders of fully paid ordinary shares, par value $0.10 per share ("Ordinary
Shares"), of Whitehall Corporation ("Whitehall"), pursuant to the terms of the
Merger Agreement, dated March 26, 1998 (the "Merger Agreement"), Whitehall will
become a wholly-owned subsidiary of the Company. In the Merger, each fully paid
Ordinary Share would be canceled in consideration of the issue of 0.5143 shares
(the "Conversion Number") of Aviation Sales Common Stock. Fractional shares
will be canceled and the holders of such shares will recieve cash in lieu of
Aviation Sales Common Stock. Stock options relating to Whitehall ordinary
shares would be transferred in amounts as provided for in the Merger Agreement,
which you have advised us will be calculated with reference to the Conversion
Number. The terms and conditions of the Merger are more fully set forth in the
Merger Agreement.


     You have requested our opinion as to whether the Conversion Number is fair
to the stockholders of the Company from a financial point of view.


     In the ordinary course of business, SBC Warburg Dillon Read Inc.
("SBCWDR") and its affiliates may actively trade or hold the equity securities
of the Company or Whitehall for their own accounts and the accounts of their
customers and, accordingly, may at any time hold a long or short position in
such securities.


     Our opinion does not address the Company's underlying business decision to
effect the Merger or constitute a recommendation to any stockholder of the
Company as to how such stockholder should vote with respect to the Merger. Our
opinion does not reflect any conclusion as to the likely trading range for
Aviation Sales Common Stock following the consummation of the Merger, which may
vary depending on numerous factors which generally influence the prices of
securities. With your consent, we have assumed that the Merger will not result
in taxable income for the Company or its stockholders and will be accounted for
as a pooling-of-interests.


     In arriving at our opinion, we have, among other things: (i) reviewed
certain publicly available business and historical financial information
relating to the Company and Whitehall, (ii) reviewed certain internal financial
information and other data relating to the business and prospects of the
Company, including financial estimates, that were provided to us by the Company
and are not publicly available, (iii) reviewed certain internal financial
information and other data relating to the business and prospects of Whitehall,
including financial estimates, provided by the management of the Company, that
were provided to us by the management of the Company and are not publicly
available, (iv) conducted discussions with members of the senior management of
the Company and Whitehall with respect to the operations, financial condition,
history and prospects of each company, (v) reviewed the historical market
prices and trading activity of the common stocks of the Company and Whitehall,
(vi) considered certain pro forma effects of the Merger on the financial
results of the Company (including the effects of


                                      B-1
<PAGE>

assumed combination savings and synergies that were provided to us by the
Company), (vii) reviewed publicly available financial and stock market data
with respect to certain other companies that we believe to be generally
comparable to the Company and Whitehall, (viii) compared to the financial terms
of the Merger with financial terms of certain other transaction that we believe
to be releveant, (ix) considered the strategic implications of the merger as
presented to us by management of the Company, (x) reviewed drafts of the Merger
Agreement, and (xi) conducted such other financial studies, analyses, and
investigations, and considered such other information as we deemed necessary or
appropriate.


     In connection with our review and arriving at our opinion, we have not,
with your consent, assumed any responsibility for independent verification of
any of the information reviewed by us for the purpose of this opinion and have,
with your consent, relied on its being complete and accurate in all material
respects. In addition, with your consent, we have not made any independent
evaluation or appraisal of any of the assets or liabilities (contingent or
otherwise) of the Company or Whitehall nor have we been furnished with any such
evaluation or appraisal. With respect to the financial estimates (including the
effects of assumed Merger savings and synergies) provided to or otherwise
reviewed by or discussed with us, we have assumed, with your consent, that they
have been reasonably prepared on bases reflecting the best currently available
estimates and judgements of the Company's management as to the future financial
performance of each company and that they will be realized in the amounts and
at the times contemplated thereby. At your direction, we have assumed that
there will be no material difference between the actual financial results which
will be obtained by the Company, Whitehall or the combined company and those
specified in the estimates, forecasts and projections provided to us. With
respect to the business and financial information pertaining to Whitehall, we
have not held any independent discussions with Whitehall management as to any
aspect of the information provided. Our opinion necessarily is based upon
economic, monetary, market and other conditions as in effect, and the
information made available to us as of, the date hereof. SBCWDR expressly
reserves its right to withdraw, revise or modify its opinion based upon
additional information provided to it or obtained by it which suggests, in
SBCWDR's judgment, a material adverse change in the assumptions upon which this
opinion is based.


     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Conversion Number is fair to the stockholders of the Company
from a financial point of view.



                                        Very truly yours,



                                        /s/ SBC WARBURG DILLON READ INC.

                    VOTING AGREEMENT AND IRREVOCABLE PROXY


     THIS VOTING AGREEMENT AND IRREVOCABLE PROXY (the "Agreement") is entered
into as of March 26, 1998, between the undersigned stockholders (the
"Stockholders") of AVIATION SALES COMPANY, a Delaware corporation ("AVS") and
WHITEHALL CORPORATION, a Delaware corporation (the "Company").


     WHEREAS, concurrently with the execution and delivery of this Agreement,
WHC ACQUISITION CORP., a Delaware corporation, and a wholly owned subsidiary of
AVS ("Newco"), AVS and the Company have entered into an Agreement and Plan of
Merger dated as of March 26, 1998 (the "Merger Agreement"), providing for the
merger of Newco with and into the Company (the "Merger") pursuant to the terms
and conditions of the Merger Agreement, and setting forth certain
representations, warranties, covenants and agreements of the parties thereto in
connection with the Merger; and


     WHEREAS, as an inducement and a condition to Company entering into the
Merger Agreement, pursuant to which each stockholder of the Company, subject to
Section 1.4 of the Merger Agreement, will receive 0.5143 of a share of AVS
Common Stock (as defined in the Merger Agreement) in exchange for each share of
Common Stock, par value $0.10 per share, of the Company ("Company Common
Stock") owned by such stockholder, the Stockholders each have agreed to enter
into this Agreement;


     NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:


     1. REPRESENTATIONS OF STOCKHOLDERS. Each of the Stockholders severally
represents as to himself or itself that such Stockholder:


      (a) is the holder in the capacity set forth on Exhibit A hereto of that
number of shares of AVS Common Stock set forth opposite such Stockholder's name
on Exhibit A (such Stockholder's shares of AVS Common Stock, the "Shares");


      (b) does not beneficially own (as such term is defined in the Securities
Exchange Act of 1934, as amended (the "1934 Act")) any shares of AVS Common
Stock other than his or its Shares, but excluding any shares of AVS Common
Stock which such Stockholder has the right to obtain upon the exercise of stock
options outstanding on the date hereof;


      (c) has the right, power and authority to execute and deliver this
Agreement and to perform his or its obligations under this Agreement, and this
Agreement has been duly executed and delivered by such Stockholder and
constitutes a valid and legally binding agreement of such Stockholder,
enforceable in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general equity
principles; and such execution, delivery and performance by Stockholder of this
Agreement will not (i) conflict with, require a consent, waiver or approval
under, or result in a breach of or default under, any of the terms of any
contract, commitment or other which such Stockholder is bound; (ii) violate any
order, writ, injunction decree or statute, or any rule or regulation,
applicable to Stockholder or any of the properties or assets of Stockholder or
(iii) result in the creation of, or impose any obligation on such Stockholder
to create, any lien, charge or other encumbrance of any nature whatsoever upon
the Shares; and


      (d) the Shares are now and will at all times during the term of this
Agreement be held by such Stockholder, or by a nominee or custodian for the
account of such Stockholder, free and clear of all


                                      C-1
<PAGE>

pledges, liens, proxies, claims, shares, security interests, preemptive rights
and any other encumbrances whatsoever with respect to the ownership, transfer
or voting of such Shares except as set forth in the AVS Reports (as defined in
the Merger Agreement); and there are no outstanding options, warrants or rights
to purchase or acquire, or other agreements relating to, such Shares other than
this Agreement.


The representations and warranties contained herein shall be made as the date
hereof and as of each date from the date hereof through and including the date
that the Merger is consummated.


     2. AGREEMENT TO VOTE SHARES. Each of the Stockholders severally agrees to
vote his or its Shares and any New Shares (as defined in Section 7 hereof), and
shall cause any holder of record of its Shares or New Shares to vote, (a) in
favor of adoption and approval of the Merger Agreement and the Merger (and each
other action and transaction contemplated by the Merger Agreement and this
Agreement) at every meeting of the stockholders of AVS at which such matters
are considered (each, an "AVS Stockholder Meeting") and at every adjournment
thereof and (b) against any actions or approval that would compete with or
could serve to materially interfere with, delay, discourage, adversely affect
or inhibit the timely consummation of the Merger. Any such vote shall be cast
or consent shall be given in accordance with such procedures relating thereto
as shall ensure that it is duly counted for purposes of determining that a
quorum is present and for purposes of recording the results of such vote or
consent. Each Stockholder also agrees to use his or its reasonable efforts to
take, or cause to be taken, all action, and do, or cause to be done, all things
necessary or advisable in order to consummate and make effective the
transactions contemplated by this Agreement.


     3. IRREVOCABLE PROXY. Each of the Stockholders hereby constitutes and
appoints Company, any nominee of Company, with full power of substitution, as
its true and lawful attorney and proxy and hereby authorizes each, for and in
its name, place and stead, to present and to vote all of the Shares and New
Shares (a) in favor of the adoption and approval of the Merger Agreement and
the Merger (and each other action and transaction contemplated by the Merger
Agreement and this Agreement) and (b) against any action or approval that would
compete with or could serve to materially interfere with, delay, discharge,
adversely affect or inhibit the timely consummation of the Merger Agreement, at
every AVS Stockholder Meeting and at every adjournment or postponement thereof,
to the same extent and with the same effect as the Stockholder might or could
do under applicable law, rules and regulations. The proxy granted pursuant to
the immediately preceding sentence is given in consideration of and as an
inducement to Company to enter into the Merger Agreement and as such is coupled
with an interest and shall be irrevocable unless and until this Agreement
terminates pursuant to Section 11 hereof. Each of the Stockholders hereby
revokes any and all previous proxies granted with respect to any of the Shares
and shall not hereafter, unless and until this Agreement terminates pursuant to
Section 11 hereof, purport to grant any other proxy or power of attorney with
respect to any of the Shares or the New Shares or enter into any agreement
(other than this Agreement), arrangement or understanding with any person,
directly or indirectly, to vote, grant any proxy or give instructions with
respect to the voting of any of the Shares or the New Shares covering the
subject matter hereof.


     4. NO VOTING TRUSTS. After the date hereof, the Stockholders severally
agree that they will not, nor will they permit any entity under their control
to, deposit any of their Shares in voting trust or subject any of their Shares
to any arrangement with respect to the voting of such Shares other than
agreements entered into with the Company.


     5. NO PROXY SOLICITATIONS. Each of the Stockholders severally agrees that
such Stockholder will not, nor will such Stockholder permit any entity under
their control to, (a) solicit proxies or become a "participant" in a
"solicitation" (as such terms are defined in Regulation 14A under the 1934 Act)
in opposition to or competition with the consummation of the Merger or
otherwise encourage or assist any party in taking or planning any action which
would compete with or otherwise could serve to materially interfere with,
delay, discourage, adversely affect or inhibit the timely consummation of the
Merger in accordance with the terms of the Merger Agreement, (b) directly or
indirectly encourage, initiate or cooperate in a stockholders' vote or action
by consent of AVS's stockholders in opposition to or in competition with the
consummation of the Merger, or (c) become a member of a "group" (as such term


                                      C-2
<PAGE>

is used in Section 13(d) of the 1934 Act) with respect to any voting securities
of AVS for the purpose of opposing or competing with the consummation of the
Merger.


     6. TRANSFER AND ENCUMBRANCE. Except as set forth on Exhibit B hereto, on
or after the date hereof, each of the Stockholders severally agrees not to
voluntarily transfer, sell, offer, pledge or otherwise dispose of or encumber
("Transfer") any of his or its Shares or New Shares prior to the earlier of (a)
the effective date of the Merger or (b) the date this Agreement shall be
terminated in accordance with its terms.


     7. ADDITIONAL PURCHASES. Each of the Stockholders severally agrees that in
the event (i) any stock dividend, stock split, recapitalization,
reclassification, combination or exchange of shares of capital stock of AVS on,
of or affecting the Shares of a Stockholder, (ii) such Stockholder purchases or
otherwise acquires beneficial ownership of any shares of AVS Common Stock after
the execution of this Agreement, or (iii) such Stockholder voluntarily acquires
the right to vote any shares of AVS Common Stock other than the Shares
(collectively, "New Shares"), such Stockholder agrees that all such New Shares
acquired or purchased by it shall be subject to the terms of this Agreement to
the same extent as if they constituted Shares.


     8. SPECIFIC PERFORMANCE. Each party hereto severally acknowledges that it
will be impossible to measure in money the damage to the other party of the
party hereto fails to comply with any of the obligations imposed by this
Agreement, that every such obligation is material and that, in the event of any
such failure, the other party will not have an adequate remedy at law or
damages. Accordingly, each party hereto severally agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of
such relief on the basis that the other party has an adequate remedy at law.
Each party hereto severally agrees that it will not seek, and agrees to waive
any requirement for, the securing or posting of a bond in connection with any
other party's seeking or obtaining such equitable relief.


     9. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns and shall not be assignable without the written consent of all other
parties hereto.


     10. ENTIRE AGREEMENT. This Agreement supersedes all prior agreements,
written or oral, among the parties hereto with respect to the subject matter
hereof and contains the entire agreement among the parties with respect to the
subject matter hereof. This Agreement may not be amended, supplemented or
modified, and no provisions hereof may be modified or waived, except by an
instrument in writing signed by all the parties hereto. No waiver of any
provisions hereof by any party shall be deemed a waiver of any other provisions
hereof by any such party, nor shall any such waiver be deemed a continuing
waiver of any provision hereof by such party.


     11. MISCELLANEOUS.


      (a) This Agreement shall be deemed a contract made under, and for all
purposes shall be construed in accordance with, the laws of the State of
Delaware.


      (b) If any provision of this Agreement or the application of such
provision to any person or circumstances shall be held invalid by a court of
competent jurisdiction, the remainder of the provision held invalid and the
application of such provision to persons or circumstances, other than the party
as to which it is held invalid, shall not be affected.


      (c) This Agreement may be executed in one or more counterparts, each of
which shall be deemed to be an original but all of which together shall
constitute one and the same instrument.


      (d) This Agreement shall terminate upon the earliest to occur of (i) the
effective time of the Merger, and (ii) termination of the Merger Agreement.

                    VOTING AGREEMENT AND IRREVOCABLE PROXY


     THIS VOTING AGREEMENT AND IRREVOCABLE PROXY (the "Agreement") is entered
into as of March 26, 1998, between the undersigned stockholders (the
"Stockholders") of WHITEHALL CORPORATION, a Delaware corporation (the
"Company"), and AVIATION SALES COMPANY, a Delaware corporation ("AVS").


     WHEREAS, concurrently with the execution and delivery of this Agreement,
WHC ACQUISITION CORP., a Delaware corporation, and a wholly owned subsidiary of
AVS ("Newco"), AVS and the Company have entered into an Agreement and Plan of
Merger dated as of March 26, 1998 (the "Merger Agreement"), providing for the
merger of Newco with and into the Company (the "Merger") pursuant to the terms
and conditions of the Merger Agreement, and setting forth certain
representations, warranties, covenants and agreements of the parties thereto in
connection with the Merger; and


     WHEREAS, as an inducement and a condition to AVS entering into the Merger
Agreement, pursuant to which each Stockholder, subject to Section 1.4 of the
Merger Agreement, will receive 0.5143 of a share of AVS Common Stock (as
defined in the Merger Agreement) in exchange for each share of Common Stock,
par value $0.10 per share, of the Company ("Company Common Stock") owned by
such Stockholder, the Stockholders each have agreed to enter into this
Agreement;


     NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:


     1. REPRESENTATIONS OF STOCKHOLDERS. Each of the Stockholders severally
represents as to itself that such Stockholder:


      (a) is the holder in the capacity set forth on Exhibit A hereto of that
number of shares of Company Common Stock set forth opposite such Stockholder's
name on Exhibit A (such Stockholder's shares of Company Common Stock, the
"Shares");


      (b) does not beneficially own (as such term is defined in the Securities
Exchange Act of 1934, as amended (the "1934 Act")) any shares of Company Common
Stock other than its Shares, but excluding any shares of Company Common Stock
which such Stockholder has the right to obtain upon the exercise of stock
options outstanding on the date hereof;


      (c) has the right, power and authority to execute and deliver this
Agreement and to perform its obligations under this Agreement, and this
Agreement has been duly executed and delivered by such Stockholder and
constitutes a valid and legally binding agreement of such Stockholder,
enforceable in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general equity
principles; and such execution, delivery and performance by Stockholder of this
Agreement will not (i) conflict with, require a consent, waiver or approval
under, or result in a breach of or default under, any of the terms of any
contract, commitment or other which such Stockholder is bound; (ii) violate any
order, writ, injunction decree or statute, or any rule or regulation,
applicable to Stockholder or any of the properties or assets of Stockholder or
(iii) result in the creation of, or impose any obligation on such Stockholder
to create, any lien, charge or other encumbrance of any nature whatsoever upon
the Shares; and


      (d) the Shares are now and will at all times during the term of this
Agreement be held by such Stockholder, or by a nominee or custodian for the
account of such Stockholder, free and clear of all


                                      D-1
<PAGE>

pledges, liens, proxies, claims, shares, security interests, preemptive rights
and any other encumbrances whatsoever with respect to the ownership, transfer
or voting of such Shares; and there are no outstanding options, warrants or
rights to purchase or acquire, or other agreements relating to, such Shares
other than this Agreement.


The representations and warranties contained herein shall be made as the date
hereof and as of each date from the date hereof through and including the date
that the Merger is consummated.


     2. AGREEMENT TO VOTE SHARES. Each of the Stockholders severally agrees to
vote its Shares and any New Shares (as defined in Section 7 hereof), and shall
cause any holder of record of its Shares or New Shares to vote, (a) in favor of
adoption and approval of the Merger Agreement and the Merger (and each other
action and transaction contemplated by the Merger Agreement and this Agreement)
at every meeting of the stockholders of the Company at which such matters are
considered (each, a "Company Stockholder Meeting") and at every adjournment
thereof and (b) against any actions or approval that would compete with or
could serve to materially interfere with, delay, discourage, adversely affect
or inhibit the timely consummation of the Merger including, without limitation,
any Alternative Proposal (as defined in the Merger Agreement). Any such vote
shall be cast or consent shall be given in accordance with such procedures
relating thereto as shall ensure that it is duly counted for purposes of
determining that a quorum is present and for purposes of recording the results
of such vote or consent. Each Stockholder also agrees to use its reasonable
efforts to take, or cause to be taken, all action, and do, or cause to be done,
all things necessary or advisable in order to consummate and make effective the
transactions contemplated by this Agreement.


     3. IRREVOCABLE PROXY. Each of the Stockholders hereby constitutes and
appoints AVS or any nominee of AVS, with full power of substitution, as its
true and lawful attorney and proxy and hereby authorizes each, for and in its
name, place and stead, to present and to vote all of the Shares and New Shares
(a) in favor of the adoption and approval of the Merger Agreement and the
Merger (and each other action and transaction contemplated by the Merger
Agreement and this Agreement) and (b) against any action or approval that would
compete with or could serve to materially interfere with, delay, discharge,
adversely affect or inhibit the timely consummation of the Merger Agreement,
including, without limitation, any Alternative Proposal (as defined in the
Merger Agreement), at every Company Stockholder Meeting and at every
adjournment or postponement thereof, to the same extent and with the same
effect as the Stockholder might or could do under applicable law, rules and
regulations. The proxy granted pursuant to the immediately preceding sentence
is given in consideration of and as an inducement to AVS to enter into the
Merger Agreement and as such is coupled with an interest and shall be
irrevocable unless and until this Agreement terminates pursuant to Section 11
hereof. Each of the Stockholders hereby revokes any and all previous proxies
granted with respect to any of the Shares and shall not hereafter, unless and
until this Agreement terminates pursuant to Section 11 hereof, purport to grant
any other proxy or power of attorney with respect to any of the Shares or the
New Shares or enter into any agreement (other than this Agreement), arrangement
or understanding with any person, directly or indirectly, to vote, grant any
proxy or give instructions with respect to the voting of any of the Shares or
the New Shares covering the subject matter hereof.


     4. NO VOTING TRUSTS. After the date hereof, the Stockholders severally
agree that they will not, nor will they permit any entity under their control
to, deposit any of their Shares in voting trust or subject any of their Shares
to any arrangement with respect to the voting of such Shares other than
agreements entered into with AVS or Newco.


     5. NO PROXY SOLICITATIONS. Each of the Stockholders severally agrees that
such Stockholder will not, nor will such Stockholder permit any entity under
their control to, (a) solicit proxies or become a "participant" in a
"solicitation" (as such terms are defined in Regulation 14A under the 1934 Act)
in opposition to or competition with the consummation of the Merger or
otherwise encourage or assist any party in taking or planning any action which
would compete with or otherwise could serve to materially interfere with,
delay, discourage, adversely affect or inhibit the timely consummation of the
Merger in accordance with the terms of the Merger Agreement, (b) directly or
indirectly encourage, initiate or


                                      D-2
<PAGE>

cooperate in a stockholders' vote or action by consent of the Company's
stockholders in opposition to or in competition with the consummation of the
Merger, or (c) become a member of a "group" (as such term is used in Section
13(d) of the 1934 Act) with respect to any voting securities of the Company for
the purpose of opposing or competing with the consummation of the Merger;
provided, that the foregoing shall not restrict any director of the Company
from taking any action such director believes is necessary to satisfy such
director's fiduciary duty to stockholders of the Company.


     6. TRANSFER AND ENCUMBRANCE. On or after the date hereof, each of the
Stockholders severally agrees not to voluntarily transfer, sell, offer, pledge
or otherwise dispose of or encumber ("Transfer") any of its Shares or New
Shares prior to the earlier of (a) the effective date of the Merger or (b) the
date this Agreement shall be terminated in accordance with its terms.


     7. ADDITIONAL PURCHASES. Each of the Stockholders severally agrees that in
the event (i) any stock dividend, stock split, recapitalization,
reclassification, combination or exchange of shares of capital stock of the
Company on, of or affecting the Shares of a Stockholder, (ii) such Stockholder
purchases or otherwise acquires beneficial ownership of any shares of Company
Common Stock after the execution of this Agreement, or (iii) such Stockholder
voluntarily acquires the right to vote any shares of Company Common Stock other
than the Shares (collectively, "New Shares"), such Stockholder agrees that all
such New Shares acquired or purchased by it shall be subject to the terms of
this Agreement to the same extent as if they constituted Shares.


     8. SPECIFIC PERFORMANCE. Each party hereto severally acknowledges that it
will be impossible to measure in money the damage to the other party of the
party hereto fails to comply with any of the obligations imposed by this
Agreement, that every such obligation is material and that, in the event of any
such failure, the other party will not have an adequate remedy at law or
damages. Accordingly, each party hereto severally agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of
such relief on the basis that the other party has an adequate remedy at law.
Each party hereto severally agrees that it will not seek, and agrees to waive
any requirement for, the securing or posting of a bond in connection with any
other party's seeking or obtaining such equitable relief.


     9. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns and shall not be assignable without the written consent of all other
parties hereto.


     10. ENTIRE AGREEMENT. This Agreement supersedes all prior agreements,
written or oral, among the parties hereto with respect to the subject matter
hereof and contains the entire agreement among the parties with respect to the
subject matter hereof. This Agreement may not be amended, supplemented or
modified, and no provisions hereof may be modified or waived, except by an
instrument in writing signed by all the parties hereto. No waiver of any
provisions hereof by any party shall be deemed a waiver of any other provisions
hereof by any such party, nor shall any such waiver be deemed a continuing
waiver of any provision hereof by such party.


                                      D-3
<PAGE>

     11. MISCELLANEOUS.


      (a) This Agreement shall be deemed a contract made under, and for all
purposes shall be construed in accordance with, the laws of the State of
Delaware.


      (b) If any provision of this Agreement or the application of such
provision to any person or circumstances shall be held invalid by a court of
competent jurisdiction, the remainder of the provision held invalid and the
application of such provision to persons or circumstances, other than the party
as to which it is held invalid, shall not be affected.


      (c) This Agreement may be executed in one or more counterparts, each of
which shall be deemed to be an original but all of which together shall
constitute one and the same instrument.


      (d) This Agreement shall terminate upon the earliest to occur of (i) the
effective time of the Merger, and (ii) termination of the Merger Agreement.


      (e) All Section headings herein are for convenience of reference only and
are not part of this Agreement, and no construction or reference shall be
derived therefrom.


      (f) The obligations of the Stockholders set forth in this Agreement shall
not be effective or binding upon any Stockholder until after such time as the
Merger Agreement is executed and delivered by the Company, AVS and Newco, and
the parties agree that there is not and has not been any other agreement,
arrangement or understanding between the parties hereto with respect to the
matters set forth herein.


     IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the date first written above.
