                  (f) Cambridge is a Delaware limited partnership. Each of its 
                      general partners are U.S. citizens.

ITEM 3.    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

           Cambridge originally acquired for investment purposes shares of
           common stock of Whitehall Corporation, a Delaware corporation
           ("Whitehall"), on margin and using its working capital. Pursuant to
           the Merger Agreement (as defined below), shares of Whitehall common
           stock were converted into shares of the Common Stock of the
           Registrant. No part of the purchase price of the shares of Whitehall
           common stock (or the Registrant's Common Stock upon conversion) was
           represented by funds or other consideration otherwise borrowed or
           obtained for the specific purpose of acquiring, holding, trading or
           voting the shares of such stock. Should Cambridge make additional
           purchases of the Registrant's Common Stock, it reserves the right to
           purchase such additional shares on margin or with funds or other
           consideration borrowed or otherwise obtained for the purpose of
           acquiring, holding, trading or voting such shares. In addition,
           Cambridge may margin or otherwise use the shares of the Registrant's
           Common Stock presently owned by it as collateral for the purposes of
           obtaining loans. In addition, pursuant to the Merger Agreement,
           Baker, who held options to purchase shares of common stock of
           Whitehall, had such options converted into options to purchase shares
           of the Common Stock of the Registrant.

ITEM 4.    PURPOSE OF TRANSACTION

           On July 31, 1998 (the "Effective Time"), the Registrant consummated a
           merger (the "Merger") pursuant to an Agreement and Plan of Merger
           (the "Merger Agreement") among the Registrant, WHC Acquisition Corp.,
           a Delaware corporation and a wholly-owned subsidiary of the
           Registrant ("Sub") and Whitehall in a transaction, pursuant to which
           each outstanding share of common stock of Whitehall was converted
           into .5143 shares of the Registrant's Common Stock. In addition, at
           the Effective Time, outstanding options to purchase shares of
           Whitehall common stock were converted into a right to purchase that
           number of shares of the Registrant's Common Stock as the holder would
           have been entitled to receive had such holder exercised such options
           prior to the Effective Time and participated in the Merger.
           Accordingly, the shares of Registrant's Common Stock acquired by
           Cambridge were a result of such share-for-share exchange. In
           addition, the options to purchase shares of the Common Stock of the
           Registrant acquired

           by Baker were also a result of such exchange. Pursuant to the Merger,
           Baker and Jeffrey N. Greenblatt ("Greenblatt"), a general partner of
           Cambridge, were both appointed as directors of the Registrant.

           Depending upon then general economic and business conditions, the
           financial condition and results of operations of the Registrant, and
           the financial requirements of Cambridge, Baker and Nye, respectively,
           each of such party may seek to acquire additional securities of the
           Registrant, may seek to dispose of all or a portion of its respective
           investments in the Registrant, or may continue to hold said shares
           for its own account. Neither Cambridge, nor Baker nor Nye has any
           current plans or proposals that may have or which may relate to or
           would result in (a) the acquisition by any person of additional
           securities of the Registrant, or the disposition of securities of the
           Registrant; (b) an extraordinary corporate transaction, such as a
           merger, reorganization or liquidation, involving the Registrant or
           any of its subsidiaries; (c) a sale or transfer of a material amount
           of assets of the Registrant or any of its subsidiaries; (d) any
           change in the present Board of Directors or management of the
           Registrant, including any plans or proposals to change the number or
           term of directors or to fill any existing vacancies on the Board of
           Directors; (e) any material change in the present capitalization or
           dividend policy of the Registrant; (f) any other material change in
           the Registrant's business or corporate structure; (g) any changes in
           the Registrant's charter, bylaws or instruments corresponding thereto
           or other actions which may impede the acquisition of control of the
           Registrant by any person; (h) causing a class of securities of the
           Registrant to be delisted from a national securities exchange or
           cease to be authorized to be quoted in an inter-dealer quotation
           system of a registered national securities association; (i) causing a
           class of equity securities of the Registrant to become eligible for
           termination of registration pursuant to Section 12(g)(4) of the
           Securities Exchange Act of 1934; or (j) any actions similar to any of
           those enumerated above.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER

           (a)     Cambridge may be deemed to directly beneficially own 675,995
                   shares of the Registrant's Common Stock or approximately 5.6%
                   of the total issued and outstanding shares of the
                   Registrant's Common Stock (based on 11,989,164 shares of the
                   Registrant's Common Stock issued and outstanding at the close
                   of business on August 12, 1998, as reported by the
                   Registrant's transfer agent). All such shares

                   are owned of record by Cambridge which has the sole voting
                   and dispositive power as to such shares.

           (b)     In addition to each being managing general partners of 
                   Cambridge, Baker and Nye are also each managing general
                   partners of Baker Nye, L.P. ("Baker Nye"). Baker Nye may be
                   deemed to directly beneficially own 297,779 shares of the
                   Registrant's common stock or approximately 2.5% of the total
                   issued and outstanding shares of the Registrant's Common
                   Stock (based on 11,989,164 shares of the Registrant's Common
                   Stock issued and outstanding at the close of business on
                   August 12, 1998, as reported by the Registrant's transfer
                   agent). All such shares are owned of record by Baker Nye,
                   which has the sole voting and dispositive power as to such
                   shares.

                   Pursuant to the limited partnership agreements of both
                   Cambridge and Baker Nye, each partnership is managed by the
                   managing general partners, and no general partner other than
                   the managing general partners of each partnership, has the
                   power to vote or to direct the vote or to dispose or direct
                   the disposition of the Common Stock of the Registrant owned
                   by each such partnership. Accordingly, Baker and Nye, as the
                   managing general partners of both Cambridge and Baker Nye,
                   may be deemed to have the shared power to direct the vote or
                   the disposition of the shares of Common Stock of the
                   Registrant held by both Cambridge and Baker Nye, and
                   accordingly, may be deemed, for purposes of determining
                   beneficial ownership pursuant to Rule 13d-3 of the Act, to
                   each be indirect beneficial owners of the 675,995 shares of
                   Common Stock of the Registrant held by Cambridge and the
                   297,779 shares of the Common Stock of the Registrant held by
                   Baker Nye (or, in the aggregate, 7.8% of the total issued and
                   outstanding shares of the Registrant's Common Stock). Each of
                   Baker and Nye hereby disclaim beneficial ownership of such
                   shares held by Cambridge and Baker Nye, for any other
                   purpose. In addition, Baker is deemed to own directly,
                   options to purchase an additional 72,002 shares of the
                   Registrant's Common Stock over which he has sole voting and
                   dispositive power or an additional .60% of the total issued
                   and outstanding shares of the Registrant's Common Stock
                   (based on 11,989,164 shares of the Registrant's Common Stock
                   issued and outstanding at the close of business on August 12,
                   1998, as reported

                         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

     1.1 THE MERGER. Upon the terms and subject to the conditions of this
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
Akerman, Senterfitt & Eidson, P.A., SunTrust International Center, One S.E.
Third Avenue, Suite 2800, Miami, Florida 33131 on the date of the last of the
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
parties hereto as the Effective Time in the Certificate of Merger (the
"Effective Time"). The Merger shall have the effects set forth in Sections 259,
260 and 261 of the General Corporation Law of the State of Delaware (the
"DGCL"). Without limiting the generality of the foregoing, and subject thereto,
at the Effective Time, the Surviving Corporation shall possess all the rights,
privileges, powers and franchises and be subject to all of the restrictions,
disabilities and duties of the Company and AVS Sub.

     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,

      (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

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

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

                                      B-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

                                      B-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.

                                      B-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 II

             CERTAIN MATTERS RELATING TO THE SURVIVING CORPORATION

     2.1 CERTIFICATE OF INCORPORATION OF THE SURVIVING CORPORATION. The
certificate of incorporation of AVS Sub in effect at the Effective Time shall
be the certificate of incorporation of the Surviving Corporation until amended
in accordance with its terms and pursuant to applicable law; provided however,
that Article I of the Certificate of Incorporation of the Surviving Corporation
shall be amended to read as follows: "The name of the corporation is Whitehall
Corporation."

     2.2 BY-LAWS OF THE SURVIVING CORPORATION. The By-Laws of AVS Sub in effect
at the Effective Time shall be the By-Laws of the Surviving Corporation until
amended in accordance with the terms of such By-Laws and pursuant to applicable
law and the Certificate of Incorporation of the Surviving Corporation.

     2.3 OFFICERS AND DIRECTORS OF THE SURVIVING CORPORATION. The officers and
directors of AVS Sub immediately prior to the Effective Time shall be the
officers and directors of the Surviving Corporation immediately after the

                                  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

                                      B-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

                                      B-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

                                      B-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

                                      B-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.

                                      B-9

Statement.

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
warranties contained in this Section 3.15(i) shall not be deemed to be breached
by any prospective general increase in real estate taxes.)

      (i) There is no assessment for Taxes (in addition to the normal, annual
general real estate tax assessment) pending against AVS or any of the AVS
Subsidiaries, or to AVS's knowledge, threatened with respect to any portion of

AVS or any of the AVS Subsidiaries is liable for payment of the real estate
leased by them.

stockholders, employees, agents or representatives has made, directly or
indirectly, with respect to AVS, the AVS 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 AVS or
the AVS 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.

     3.19 ABSENCE OF INDEMNIFIABLE CLAIMS, ETC. There are no pending claims
and, to the knowledge of AVS, no facts that would reasonably entitle any
director, officer or employee of AVS or the AVS

                                      B-11
<PAGE>

<PAGE>

requirements of the Securities Act or the Exchange Act, as the case may be, and
the rules and regulations thereunder. None of the Company Reports contain 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.
The Company has filed with the SEC all reports required to be filed under

and schedules) fairly present in all material respects the results of
operations, retained earnings or cash flows, as the case may be, of the Company
and its Subsidiaries for the periods set forth therein (subject, in the case of

non-recurring items of income or expense during the periods covered by such
financial statements and the consolidated balance sheets of the Company
included or incorporated therein do not reflect any write-up or revaluation
increasing the book value of any assets, except as specifically disclosed in
the notes thereto. Except as and to the extent reflected or reserved against in
the financial statements included in the Company's Quarterly Report on Form
10-Q for the quarter ended September 30, 1997 (the "Company Form 10-Q") or as
disclosed therein, neither the Company nor any Company Subsidiary 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 condition of the Company and its Subsidiaries taken as
a whole. Since September 30, 1997, neither the Company nor any Company
Subsidiary has incurred any liability or obligation of any kind which, in any

a whole, except in the ordinary course of business. The financial statements of
the Company, including the notes thereto, included in or incorporated by
reference into the Company 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 GAAP. Since January 1, 1993, there has
been no material change in the Company's accounting methods or principles that
would be required to be disclosed in the Company's financial statements in
accordance with GAAP, except as described in the notes to such Company
financial statements.

     4.11 ADEQUACY OF PROPERTIES; INTANGIBLE PROPERTY.

businesses and operations and, except as otherwise disclosed in the Company
Reports filed with the Commission prior to the date hereof, the Company and its
Subsidiaries have good and marketable title to or valid leasehold or other
contractual interests in such properties and assets, free and clear of all
Liens other than Permitted Encumbrances.

      (b) All trade receivables and notes receivables which are reflected in
the financial statements contained in the Company Reports or which arose
subsequent to September 30, 1997, whether billed or unbilled, arose out of bona
fide, arms-length transactions for the sale of goods or performance of
services, and to the Company's knowledge, all such trade receivables and notes
receivable are good and collectible (or have been collected) in the ordinary
course of business using normal collection practices at the aggregate recorded
amounts thereof, less the amount of applicable reserves for doubtful accounts
and for allowances and discounts, which reserves are adequate in accordance
with GAAP.

      (c) All inventory of the Company or any of its Subsidiaries which is held
for sale or resale, materials and supplies (collectively, "Inventory"),
consists of items of a quantity and quality historically

                                      B-15
<PAGE>

useable and/or saleable in the normal course of business. Since September 30,
1997, there has not been a material change in the level of the Inventory. All
Inventory is, and located at the Real Estate (as defined herein) or at the
Leased Premises (as defined herein).

      (d) Attached to the Disclosure Statement is a list and description of
each item of real or tangible personal property owned by the Company or any of
its Subsidiaries which has a net book value in excess of $10,000. The
Disclosure Statement lists all properties and assets used by the Company or any

remaining obligations under any such lease or agreement exceed $5,000 and such
remaining obligations extend for one year or more from the date hereof.

      (e) The Company and its Subsidiaries own or have adequate rights to use
all patents, trademarks, trade names, service marks, brands, logos, copyrights,
trade secrets, customer lists and other proprietary intellectual property
rights (including, without limitation, all computer software, unpatented
formulations, manufacturing methods, technical agreements and technical
specifications and know-how) required for, used in or incident to the
businesses of the Company and its Subsidiaries as now conducted or proposed to
be conducted. Except as otherwise described in the Company Reports, neither the
Company nor any of its Subsidiaries has received notice, and has reason to
know, of any claim or threatened infringement of the rights of others with
respect to any patents, trademarks, service marks, trade names, brands, logos,
copyrights or licenses used or owned by the Company, the loss of which could
have a Company Material Adverse Effect. The Company has no knowledge that
either it or any of its Subsidiaries is infringing upon or otherwise violating,
or has in the past infringed upon or otherwise violated, the rights of any
third party with respect to any patent, trademark, trade name, service mark or
copyright. To the knowledge of the Company, no current or former employee of
the Company of any of its Subsidiaries is or was a party to any confidentiality
agreement and/or agreement not to compete which restricts or forbids or
restricted or forbade at any time during such employee's employment by the
Company or any of its Subsidiaries, such employee's performance of the
Company's or any of its Subsidiaries' business, as the case may be, or any
activity that such employee was hired to perform. Neither the Company nor any
of its Subsidiaries is now using, and has not in the past used without
appropriate authorization, any confidential information or trade secrets of any
third party. Neither the Company nor any of its Subsidiaries has ever received
any notice alleging such conduct.

right to acquire, adverse interest, assignment, deposit arrangement,
encumbrance, restriction, lien (statutory or other), or preference, priority or

whatsoever (including any conditional sale or other title retention agreement,

the foregoing, and the filing of any financing statement under the Uniform
Commercial Code or comparable law of any jurisdiction), and (ii) the term
"Permitted Encumbrances" shall mean the following Liens with respect to the
properties and assets of the Company of any of its Subsidiaries: (A) Liens for

carriers, warehousemen, mechanics, materialmen and landlords incurred in the
ordinary course of business for sums not overdue or being contested in good
faith by appropriate proceedings and for which adequate reserves in accordance

or to secure obligations on surety or appeal bonds; and (D) purchase money

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.

      (b) With respect to all amounts in respect of Taxes imposed upon the
Company or any of its Subsidiaries, or for which the Company or any of its

<PAGE>

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 the Company or its
Subsidiaries, to taxing authorities or others, on or before the date hereof
have been paid or adequately reserved for on the financial statements contained

its Subsidiaries) which waivers are still in effect. The 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 or audits are presently being

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
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
been a party to or bound by (nor will the Company or any of its Subsidiaries
become a party to or bound by) any tax indemnity, tax sharing or tax allocation
agreement.

any of its Subsidiaries that are currently effective as of the date hereof that
are not reflected in the Company's Returns are set forth in the Disclosure
Statement.

      (g) There are no challenges on appeals pending regarding the amount of
Taxes on, or the addressed valuation of, the Real Estate or the Leased
Premises, and no special arrangements or agreements exist with any governmental
authority with respect thereto (the representations and warranties contained in
this Section 4.18(h) shall not be deemed to be breached by any prospective
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.

withdrawn from any multiemployer plan where such withdrawal has either: (i)
resulted or would result in any "withdrawal liability" (within the meaning of

transaction that might have resulted in withdrawal liability but for the
application of Section 4204 of ERISA.

otherwise made or entered into any legally binding commitment with, any
employees of the Company, any of its Subsidiaries or of any Commonly Controlled
Entity to the effect that, following the date hereof, (i) any benefits or
compensation provided to such employees under existing Benefit Plans or

by Section 4980B of the Code.

Subsidiaries and Commonly Controlled Entities with respect to Benefit Plans
under law, contract or otherwise have been made in full and on a timely basis

employee or administrator thereof in connection with the existence, operation
or administration of a Benefit Plan, other than routine claims for benefits.

the Company, any of its Subsidiaries or a Commonly Controlled Entity or Benefit
Plan is a party to the purposes of providing employee benefits; (ii) trigger a
right of any employee of the Company, any of its Subsidiaries, or any Commonly
Controlled Entity to severance, deferred compensation or retirement benefits;

                                   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.

Proxy Statement or the Form S-4. Each of the parties shall supply the other
party with copies of all correspondence between such party or any of its
representatives and the SEC with respect to any of the foregoing filings. If at

Proxy Statement, the Company Proxy Statement or the Form S-4, the parties shall
cooperate to promptly cause such amendment or supplement to be prepared, filed
with and cleared by the SEC and, if required by applicable law, disseminated to
the persons and in the manner required.

     5.8 FURTHER ACTION. Subject to the terms and conditions of this Agreement

things reasonably necessary, proper or advisable to consummate and make
effective the transactions contemplated by this Agreement as soon as reasonably
practicable, including such actions or things as any other party hereto may
reasonably request in order to cause any of the conditions to such other
party's obligation to consummate such transactions specified in Article VI to
be fully satisfied. Without limiting the generality of the foregoing, the
parties shall (and shall cause their respective Subsidiaries, and use their
reasonable efforts to cause their respective affiliates, directors, officers,
employees, agents, attorneys, accountants and representatives, to) consult and

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

                                      B-33

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

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.

     5.14 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

                                      B-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.

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

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

employees and authorized representatives to whom such documents were furnished
promptly to return such documents and any copies thereof any of them may have

defend against all actions, suits or proceedings in which such party is named

contemplated hereby or seek damages with respect to such transactions. No

                                      B-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

hereto.

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

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.

such approval; provided, however, that the Company shall not be deemed to have
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
action either (i) permanently restraining, enjoining or otherwise prohibiting
the transactions contemplated by this Agreement; or (ii) compelling AVS, 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 and the Company,
or sell or license any material product of AVS or the Company, and such order,
decree, ruling or other action shall have become final and non-appealable.

     7.3 TERMINATION BY THE COMPANY. This Agreement may be terminated and the
Merger may be abandoned at any time prior to the Effective Time, whether before
or after the adoption and approval

                                      B-39

by the stockholders of the Company or AVS, by action of the Company Board, if
(a) there has been a breach by AVS or AVS Sub of any representation or warranty
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
curable or, if curable, is not cured within 30 days after written notice of
such breach is given by the Company to AVS.

     7.4 TERMINATION BY AVS. This Agreement may be terminated and the Merger
may be abandoned at any time prior to the Effective Time, before or after the
approval by the stockholders of the Company or AVS, by action of the Board of
Directors of AVS, if (a) the Company Board shall have recommended a Superior
Proposal to the stockholders of the Company; (b) there has been a breach by the
Company of any representation or warranty contained in this Agreement which
would have a Company Material Adverse Effect; or (c) there has been a material
breach of any of the material covenants or agreements set forth in this
Agreement on the part of the Company, which breach is not curable or, if
curable, is not cured within 30 days after written notice of such breach is
given by AVS to the Company.

     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.

parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties. Subject to the preceding sentence, this

action taken by their respective Boards of Directors, at any time before or
after approval of matters presented in connection with the Merger by the
stockholders of each of the Company and AVS, but after any such stockholder
approval, no amendment shall be made which by law requires the further approval
of stockholders without obtaining such further approval. This Agreement may not
be amended except by an instrument in writing signed on behalf of each of the
parties hereto.

     8.6 GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware without regard to its rules

instrument.

for the convenience of the parties only and shall be given no substantive or

taking such action of compliance with any representations, warranties,
covenants or agreements contained in this Agreement. The waiver by any party
hereto of a breach of any provision hereunder shall not operate or be construed
as a waiver of any prior or subsequent breach of the same or any other

Disclosure Statement and all Exhibits attached hereto and referred to herein

     8.12 SEVERABILITY. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of
this Agreement is so broad as to be unenforceable, the provision shall be
interpreted to be only so broad as is enforceable.

     8.13 ENFORCEMENT OF AGREEMENT. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
was not performed in accordance with its specific terms or was otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
