ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.
 
    ACQUISITION OF AVTECH CORPORATION
 
    On June 4, 1998, the Company announced that it signed a definitive agreement
to purchase substantially all of the outstanding stock of Avtech Corporation
("Avtech"). The purchase was consummated on June 26, 1998. Avtech is a leading
provider of cockpit audio, lighting and power control devices and an avionics
systems integrator for the commercial, regional and corporate jet aircraft
markets. Avtech is located in Seattle, Washington.
 
    The total purchase price was $84.7 million in cash at closing, including an
estimated $1.3 million of acquisition related costs. The acquisition was funded
with borrowings under the Company's senior revolving line of credit ("Senior
Credit Facility"). In conjunction with the acquisition, the Senior Credit
Facility was amended to increase the permitted maximum borrowings by $30.0
million to $105.0 million, effective with the closing of the acquisition. The
permitted maximum borrowings are subject to mandatory reductions of up to $45.0
million from the proceeds of certain indebtedness and further automatic
reductions on the last day of each month in a monthly amount of $500,000 from
October 31, 1998 through May 31, 1999 and $1.0 million per month thereafter. The
maximum interest rate margins were increased 0.25% to 1.00% above the prime rate
or 2.25% above the IBOR rate and the maximum commitment fee was increased to
0.425% on the unused portion of the Senior Credit Facility.
 
    The transaction will be accounted for as a purchase and the estimated $60.4
million difference between the purchase price and the fair value of the net
assets acquired will be recorded as goodwill and amortized on a straight-line
basis over 30 years. The Company's consolidated results of operations will
include the operating results of Avtech subsequent to June 26, 1998.
 
    Copies of the press releases issued by the Company on June 4 and 26, 1998
with respect to the Avtech acquisition are attached hereto as Exhibit 99.1 and
Exhibit 99.2, respectively, and are incorporated herein by reference.
 
    ACQUISITION OF DETTMERS INDUSTRIES, INC.
 
    On June 30, 1998, the Company purchased certain assets, subject to certain
liabilities assumed, of Dettmers Industries, Inc. ("Dettmers"). Dettmers is a
manufacturer of aircraft seats and related cabin furnishings for corporate jet
aircraft. Dettmers is located in Stuart, Florida.
 
    The total purchase price was $2.3 million in cash at closing, including an
estimated $141,000 of acquisition related costs, plus contingent consideration
aggregating a maximum of $2.0 million payable over four years based on future
attainment of defined performance criteria during each of the years in the four
year period ending December 31, 2002. The acquisition was funded with borrowings
under the Company's Senior Credit Facility.
 
    The transaction will be accounted for as a purchase and the estimated $2.0
million difference between the purchase price, excluding contingent
consideration, and the fair value of the net assets acquired will be recorded as
goodwill and amortized on a straight-line basis over 30 years. The amount of
contingent consideration paid in the future, if any, will increase goodwill and
will be amortized prospectively over the remaining period of the initial 30-year
term. The Company's consolidated results of operations will include the
operating results of Dettmers subsequent to June 30, 1998.
 
    A copy of the press release issued by the Company on July 1, 1998 with
respect to the Dettmers acquisition is attached hereto as Exhibit 99.3 and is
incorporated herein by reference.

<PAGE>
                       STOCK PURCHASE AND SALE AGREEMENT
 
    This Stock Purchase and Sale Agreement ("Agreement") is made and entered
into by and among the persons named on the signature page who are the owners of
the number of shares specified on Schedule A (the "Shareholders," some of whom
are designated on Schedule A and referred to herein as the "Principal
Shareholders") of Avtech Corporation ("Avtech") and DeCrane Aircraft Holdings,
Inc. ("DAH"), based on the following facts:
 
    Shareholders own not less than 90% of the outstanding stock of Avtech (the
"Stock"); and desire to sell the Stock to DAH;
 
    DAH desires to purchase not less than 90% of the Stock from the Shareholders
on the terms and conditions of this Agreement.
 
    Based on the foregoing facts and circumstances, the parties hereby agree as
follows (capitalized terms being used herein as defined where noted in Schedule
B):
 
    1.  STOCK TO BE PURCHASED AND SOLD; PURCHASE PRICE.
 
        1.1  PURCHASE AND SALE OF STOCK.  At the Closing, DAH shall purchase
    from the Shareholders not less than 90% and up to 100% of the Stock for the
    amount specified in Section 1.2. Schedule A reflects the percentage of the
    aggregate payments to be made pursuant to Sections 1.2.1 and 1.2.2 to each
    of the Shareholders.
 
        1.2  PURCHASE PRICE OF THE STOCK.
 
           1.2.1  On the Closing Date, DAH shall make a wire transfer in
       same-day funds to the entity agreed upon by the parties as the paying
       agent for the Shareholders (the "Paying Agent"), for the account of the
       Shareholders and to such account as the Paying Agent specifies, in a sum
       equal to the product of multiplying (a) the percentage representing the
       pro rata number of shares being sold by the Shareholders to DAH on such
       date by (b) $79 million, but subject to the adjustments set forth in
       Section 1.2.3.
 
           1.2.2  On the Closing Date, DAH shall make a wire transfer in
       same-day funds to the entity agreed upon by the parties as the escrow
       agent (the "Escrow Agent"), to be held by the Escrow Agent pursuant to
       the terms of the Escrow Agreement executed among such Escrow Agent and
       the parties thereto (the "Escrow Agreement"), in a sum equal to the
       product of multiplying (a) the percentage representing the pro rata
       number of shares being sold by the Shareholders to DAH on such date by
       (b) $4 million.
 
           1.2.3  In determining the amount pursuant to Section 1.2.1 and
       subject to the pro rata adjustment provided for in Section 1.2.1 in the
       event that DAH purchases less than 100% of the Stock, the purchase price
       shall be (i) increased by the amount of cash held by Avtech in the
       accounts listed on Schedule 2.2.12 (the "Cash") to the extent that such
       amount exceeds $650,000 (the "Minimum Amount") or decreased if the amount
       is less than the Minimum Amount by the difference between the Cash and
       the Minimum Amount at Closing.
 
               (i) to the extent there are any unpaid Shareholder Closing
           Expenses on the Closing Date, such expenses shall be paid by the
           Paying Agent; to the extent that there are Shareholder Closing
           Expenses which have been advanced by Avtech, the aggregate amount of
           such expenses shall be reimbursed to Avtech by the Paying Agent on
           the Closing Date. The sum of the amounts described in this clause (i)
           shall be deducted from the amount distributed by the Paying Agent to
           the Shareholders.

       2.2.1(a), Avtech has not received any written notice or assertion within
       the last three years from any governmental official of any jurisdiction
       to the effect that Avtech is required to be qualified or otherwise
       authorized to do business therein, in which Avtech has not qualified or
       obtained such authorization. Attached as Schedule 2.2.1(b) are complete
       and correct copies of Avtech's articles of incorporation and bylaws as in
       effect on the date hereof, and Avtech is not in default in the

       constituting all of the issued and outstanding shares of capital stock of
       any class of Avtech as of the date of this Agreement (not including any
       Avtech Common Shares attributable to the options which, as of the date of
       this Agreement, have not been exercised); all outstanding Avtech Common
       Shares have been (or will be upon exercise of the relevant options)
       validly issued and are fully paid and non-assessable and free of
       preemptive rights; except as set forth on Schedule 2.2.2, there are no

       firm reasonably satisfactory to DAH as respects each of the Delivered
       Financial Statements (including the March 31, 1998 Delivered Financial
       Statements). When such unqualified opinion is delivered, such financial
       statements shall be referred to as the "Audited Financial Statements".

    judicial, filed, pending or, to the best knowledge of any of the
    Shareholders, threatened against Avtech or the Shareholders or involving the
    Property, this Agreement or the transactions contemplated hereby, at law or
    in equity, before any federal, state or local court or regulatory agency, or
    other governmental authority, including any unfair labor practice or
    grievance, proceedings or claim. To the best knowledge of the Principal
    Shareholders, there is no basis upon which such a claim, litigation, action,
    suit or proceeding could reasonably be brought or initiated. Except as set
    forth in Schedule 2.2.17, neither any of the
 
                                       8
<PAGE>
    Shareholders nor Avtech is subject to any judgment, order or decree or any
    governmental restriction applicable to Avtech, or such Shareholders, which
    could reasonably be expected to have a Material Adverse Effect, or which
    materially adversely affects the ability of Avtech to conduct business in
    any area.
 
        2.2.18  NO CONFLICT OR DEFAULT.  Neither the execution and delivery of
    this Agreement or any other document or instrument to be executed pursuant
    to the terms hereof nor compliance with the terms and provisions hereof or
    thereof, including the consummation of the transactions contemplated hereby,
    will (a) violate in any material respect any statute, regulation or
    ordinance of any governmental authority, or (b) conflict with or result in
    the breach of any term, condition or provision of the articles of
    incorporation or bylaws of Avtech or of any agreement, deed, contract,
    mortgage, indenture, writ, order, decree, legal obligation or instrument
    (with respect to the business of Avtech) to which Avtech or any of the
    Shareholders is a party or by which Avtech or any of the Shareholders or any
    part of the Property is or may be bound, or (c) constitute a material
    default (or an event which with the lapse of time or the giving of notice,
    or both, would constitute a material default) thereunder, or (d) result in
    the creation or imposition of any material lien, charge, encumbrance, or
    restriction of any nature whatsoever with respect to any part of the
    Property, or (e) give to others any interest or rights, including rights of
    termination, acceleration or cancellation in or with respect to any part of
    the Property or the business of or any ownership interest in Avtech.
 
        2.2.19  LABOR RELATIONS.  Schedule 2.2.19 sets forth all collective
    bargaining or other labor agreements to which Avtech is bound or which
    otherwise covers employees of Avtech; and the Shareholders have previously
    delivered to DAH true, correct and complete copies of each such agreement.
    There is no labor strike, dispute, slowdown or stoppage, or any union
    organizing campaign, or petition for certification actually pending or, to
    the best knowledge of the Principal Shareholders, threatened against or
    involving Avtech. Schedule 2.2.19 sets forth all pending grievances and
    arbitration proceedings against Avtech arising out of or under a collective
    bargaining or other labor agreement. No collective bargaining or other labor
    agreement is currently being negotiated by Avtech. Avtech has not
    experienced any work stoppage or other material labor difficulty over the
    past three years. No such agreement which is binding on Avtech restricts it
    from relocating or closing any or all of its operations.
 
        2.2.20  EMPLOYEE BENEFIT PLANS.
 
           (a) Except as set forth in Schedule 2.2.20, Avtech does not currently
       sponsor, maintain or contribute, or has within the past 3 years
       sponsored, maintained or contributed to, to any pension, retirement,
       profit-sharing, deferred compensation, bonus, stock option or other
       incentive plan, or any other employee benefit program, arrangement,
       agreement or understanding, or medical, vision, dental or other health
       plan, or life insurance or disability plan, or any other employee benefit
       plan as defined in Section 3(3) of the Employee Retirement Income
       Security Act of 1974, as amended ("ERISA"), whether or not any such
       employee benefit plan is otherwise exempt from the provisions of ERISA,
       and whether or not formal or informal, written or oral, and whether or
       not legally binding. All such plans are fully funded through the date of
       this Agreement or amounts sufficient to fully fund contributions to such
       plans through the Closing Date are reserved for in the March 31, 1998
       Delivered Financial Statements. All such plans, funds or programs
       sponsored, maintained or contributed to by Avtech currently or within the
       past 3 years, whether or not listed on Schedule 2.2.20, are hereinafter
       referred to as the "Employee Benefit Plans"). For the purpose of this
       Section 2.2.20, the term "Avtech" shall include all "affiliates" of
       Avtech, whether or not incorporated, as such term is used in Section
       407(d)(7) of ERISA.
 
           (b) As of the Closing Date, neither Avtech nor any entity that may be
       regarded as under common control with Avtech pursuant to Section 414 of
       the Internal Revenue Code of 1986, as
 
                                       9
<PAGE>
       amended (the "Code"), shall have incurred any material unsatisfied
       liability under Title IV of ERISA or Section 4980 of the Code, nor shall
       any such entity have become subject to a lien pursuant to Section 412(n)
       of the Code.
 
           (c) Full payment has been made of all material amounts which Avtech
       is required, under applicable law or under any Employee Benefit Plan or
       any agreement relating to any Employee Benefit Plan to which it is a
       party, to have paid as contributions to or benefits under any Employee
       Benefit Plan as of the date hereof. To the extent required by generally
       accepted accounting principles, Avtech has made adequate provision in the
       Delivered Financial Statements for liabilities to meet current
       contributions or benefit payments.
 
           (d) Avtech has performed all obligations required to be performed by
       it under the Employee Benefit Plans, except for such non-performance as
       would not result in a material liability to Avtech. Except as would not
       result in material liability to Avtech, Avtech has not engaged in any
       transaction with respect to the Employee Benefit Plans which would
       subject Avtech or DAH to a material tax, penalty or liability for a
       prohibited transaction under Section 406, 407 or 502(i) of ERISA or
       Section 4975 of the Code, nor have Avtech's directors, officers,
       partners, employees or agents, to the extent they or any of them are
       fiduciaries with respect to such Employee Benefit Plans, breached any of
       the responsibilities or obligations imposed upon fiduciaries under Title
       I of ERISA or, to the knowledge of the Principal Shareholders, taken any
       action or failed to take any action which would result in any claim being
       made under or by or on behalf of any such Employee Benefit Plans by any
       party with standing to make such claim. Avtech will not have any plan or
       commitment, whether formal or informal, written or oral, and whether or
       not legally binding, to modify or change any Employee Benefit Plan in any
       material manner prior to the Closing Date other than changes required to
       comply with applicable laws. Avtech and, to the knowledge of the
       Principal Shareholders, any "administrator(s)" (as described in Section
       3(16)(A) of ERISA) of the Employee Benefits Plans have complied in all
       material respects with the applicable requirements of ERISA, the Code and
       all other statutes, orders, rules or regulations, specifically including
       material compliance with all reporting and disclosure requirements of
       Part 1 of Subtitle B of Title I of ERISA and of the Code in a timely and
       accurate manner, and no penalties have been or will be imposed, nor is
       Avtech, or, to the knowledge of the Principal Shareholders, any
       administrator liable for any penalties imposed, under ERISA, the Code or
       otherwise with respect to the Employee Benefit Plans or any related
       trusts of Avtech, except for such non-compliance and penalties as would
       not result in a material liability to Avtech. Avtech is not delinquent in
       the payment of any federal, state or local taxes with respect to the
       Employee Benefit Plans. There is no pending litigation, arbitration, or
       disputed claim, settlement adjudication or proceeding with respect to the
       Employee Benefit Plans, and the Principal Shareholders are not aware of
       any threatened litigation, arbitration or disputed claim, adjudication
       proceeding, or any governmental or other proceeding, or investigation
       with respect to the Employee Benefit Plans or with respect to any
       fiduciary or administrator thereof (in their capacities as such), or any
       party-in-interest within the meaning of Section 3(14) of ERISA thereto
       (with respect to their relationship as such). There is no "defined
       benefit plan" within the meaning of Section 414(j) of the Code or Section
       3(35) of ERISA to which Avtech or any entity that may be regarded as
       under common control with Avtech pursuant to Code Section 414 has been a
       party or has been required to make any contributions at any time during
       the last six (6) years. There is no "multiemployer plan" within the
       meaning of Section 3(37) of ERISA to which Avtech or any entity that may
       be regarded as under common control with Avtech pursuant to Code Section
       414 has been a party or has been required to make any contributions at
       any time during the last six (6) years.
 
           (e) The Shareholders have made available or caused to be made
       available as of the date of this Agreement to DAH true, accurate and
       complete copies of (A) all Employee Benefit Plans
 
                                       10
<PAGE>
       and any related trust agreements, custodial agreements, investment
       management agreements, insurance contracts or policies, and
       administrative service contracts, all as in effect as of the date of this
       Agreement, together with all amendments thereto which will become
       effective at a later date; (B) the latest Summary Plan Description and
       any modifications thereto for each Employee Benefit Plan requiring same
       under ERISA; (C) each Form 5500 and/or Form 990 series filing (including
       required schedules and financial statements) for the last two fiscal
       years for each Employee Benefit Plan required to file such form; and (D)
       the most recent determination letter issued by the Internal Revenue
       Service with respect to any Employee Benefit Plan. None of Avtech or any
       officer, partner, employee, representative or agent of Avtech, has made
       any written or oral representations or statements to any current or
       former employees, dependents, participants or beneficiaries or other
       persons which are inconsistent in any material manner with the provisions
       of these documents.
 
           (f) With respect to any of Avtech's employee welfare plans (as
       defined in Section 3(1) of ERISA and including those Employee Benefit
       Plans which qualify as such) which are "group health plans" under Section
       4980B of the Code and Section 607(1) of ERISA and related regulations
       (relating to the benefit continuation rights imposed by the Consolidated
       Omnibus Budget Reconciliation Act of 1985 ("COBRA"), as amended to date),
       there has been timely compliance in all material respects with all
       requirements imposed thereunder, as and when applicable to such plans, so
       that Avtech has not incurred any (or will not incur any) material loss,
       assessment, penalty, loss of federal income tax deduction or other
       sanction, arising on account of or in respect of any failure to comply
       with any COBRA benefit continuation requirement, which is capable of
       being assessed or asserted directly or indirectly against Avtech or any
       of its subsidiaries with respect to any such plan. Avtech has no
       obligation to provide medical benefits to any former employee, except as
       required by applicable law, including, but not limited to, COBRA.
 
           (g) No Employee Benefit Plan maintained by Avtech which is a "welfare
       plan" within the meaning of Section 3(1) of ERISA provides benefits to
       employees after termination of employment, except as required by
       applicable law, including, but not limited to Section 4980B of the Code
       and Part 6 of Subtitle B of Title I of ERISA.
 
           (h) The trustee of the Avtech Corporation Employee Stock Ownership
       Trust (the "ESOT Trustee" or "ESOT") is not a Shareholder or director,
       officer or employee of Avtech and has no financial interest in the
       transaction contemplated by this Agreement.
 
           2.2.21  CONTRACTS AND COMMITMENTS.  Schedule 2.2.21 is a list of all
       contracts, agreements, contract rights, leases, license agreements,
       franchise rights and agreements, policies, purchase and sales orders,
       quotations and executory commitments, instruments, guaranties,
       indemnifications, arrangements, obligations and understandings (written
       or oral) to which Avtech is a party, all without any counterclaim set-off
       or defense and which involve the payment by or to Avtech in the
       individual amount of $50,000 or in the aggregate amount of $100,000 or
       more during any year, or are otherwise necessary to the operation of the
       business of Avtech as currently conducted (the "Material Contracts").
       Each of the Material Contracts is valid and binding, in full force and
       effect and enforceable against Avtech in accordance with its respective
       provisions. Avtech has not assigned, mortgaged, pledged, encumbered, or
       otherwise hypothecated any of its right, title or interest under any
       Material Contract, or under any lease of personal property or real
       property to which Avtech is a party (herein, a "Lease") whether or not
       each Lease constitutes a Material Contract. A correct and complete copy
       of each Material Contract and Lease has previously been delivered to DAH.
       Avtech is not in violation of, in default in respect of, nor has there
       occurred an event or condition which, with the passage of time of giving
       of notice (or both) would constitute a violation or default of any
       Material Contract; and there are no facts or circumstances known to the
       Principal Shareholders which would reasonably indicate that Avtech (or
       any other party) will
 
                                       11
<PAGE>
       be or may be in violation of or in default in respect of any Material
       Contract, subsequent to the date hereof. Without limiting the foregoing,
       no consents, authorizations, approvals or similar agreements or
       acquiescence is required from any party under any Material Contract or
       Lease to any of the transactions contemplated hereby, except to the
       extent listed on Schedule 3.1.9 hereof. No notice has been received by
       Avtech claiming any such default by Avtech or indicating the desire or
       intention of any other party thereto to amend, modify, rescind or
       terminate the same.
 
           2.2.22  ACCOUNTS RECEIVABLE.  All of the accounts and notes
       receivable, investments, deposits and prepaid expenses of Avtech as of
       March 31, 1998 are set forth on Schedule 2.2.22. All accounts receivable,
       arising between March 31, 1998 and the Closing Date (in each case net of
       allowances for doubtful accounts), (a) are or will be valid and
       subsisting, (b) represent or will represent sales actually made, (c)
       arose or will arise in the ordinary and usual course of the business of
       Avtech and (d) to the extent not collected prior to the Closing Date,
       will be collectible according to their terms on or before December 31,
       1998, all without any counterclaim, set-off or defense.
 
           2.2.23  INVENTORIES.  Schedule 2.2.23 completely and accurately lists
       all raw materials, supplies, parts, work-in-process, and finished goods
       inventory and other inventory owned by Avtech and the accurate cost of
       such inventory as of March 31, 1998. Except as set forth in Schedule
       2.2.23, and except for amounts which in the aggregate are not material,
       all such inventories (i) consist of a quality and quantity usable and
       saleable in the ordinary and usual course of business, except for items
       of obsolete materials and materials of substandard quality, all of which
       have been written off or written down on the books of Avtech to net
       realizable value prior to March 31, 1998 and (ii) have been priced at the
       lower of cost or market on a FIFO basis. The quantities of all material
       portions of each type of inventory (whether raw materials, work-in-
       process, or finished goods) are not excessive, but are reasonable and
       warranted in the present circumstances of Avtech; and all material
       portions of work-in-process and finished goods inventory is free of any
       material defect or other deficiency.
 
           2.2.24  BACKLOG.  All unfilled orders to purchase goods of Avtech as
       of March 31, 1998 are set forth in Schedule 2.2.24 and are firm and
       binding commitments (subject to cancellation rights set forth therein) of
       the respective purchasers assuming the purchasers have duly authorized
       such purchases.
 
           2.2.25  BOOKS OF ACCOUNT: RECORDS.  Except as disclosed in Schedule
       2.2.25, the general ledgers, books of account and other financial records
       of Avtech are complete and correct, have been maintained in accordance
       with generally accepted accounting principles and practices and the
       matters contained therein are appropriately and accurately reflected in
       the Delivered Financial Statements in all material respects.
 
           2.2.26  OFFICERS, PARTNERS. EMPLOYEES AND COMPENSATION.  Schedule
       2.2.26 lists (i) the GMT, (ii) the AMT, (iii) the "Key Employees" who,
       for purposes of this Agreement are Steve Froebe, Test Engineering Group
       Leader, Ron Feigal, Principal Engineer, Jeff Jorgensen, Staff Engineer
       and Bill Cuffel, Staff Engineer, and (iv) any Shareholder who is an
       employee of Avtech and not included in any of the above groups, together
       with the total salary, bonus payments, fringe benefits and perquisites
       each received in each of the 3 fiscal years ended September 30, 1997,
       changes to the foregoing which have occurred since September 30, 1997,
       and the professional background of each Key Employee for the last 5 years
       to the best of the knowledge of the Principal Shareholders. There are no
       other material forms of compensation paid by Avtech to any of the persons
       named in (i) through (iv) above. The provisions for wages and salaries
       accrued on the March 31, 1998 Balance Sheet are adequate for salaries and
       wages, including accrued vacation pay, for the period up through the date
       thereof, and Avtech has accrued on its books and records all obligations
       for wages and salaries and other compensation to its employees,
       including,
 
                                       12
<PAGE>
       but not limited to, vacation pay and sick pay, and all commissions and
       other fees payable to agents, salesmen and representatives. Avtech has
       filed or will file any and all payroll tax returns due through the
       Closing Date and pay or reserve on the Closing Date Balance Sheet all
       payroll taxes due for any and all Avtech employees.
 
                   Except as set forth on Schedule 2.2.26, Avtech has not become
       obligated, directly or indirectly, to any shareholder, director, officer
       or partner of Avtech or any member of their families, except for current
       liabilities for employment compensation or director's fees. Except as set
       forth on Schedule 2.2.26, no shareholder, director, officer, partner,
       agent or employee of Avtech holds any position or office with or has any
       financial interest, direct or indirect, in any supplier, customer or
       account of, or other outside business which has transactions with Avtech.
       Neither Avtech, nor any third party, has taken any action with respect to
       any shareholder, director, officer, partner, employee or representative
       of Avtech to attempt to induce or which would influence any such person
       not to become associated with DAH from and after the Closing Date or from
       serving DAH in a capacity similar to the capacity presently held. To the
       knowledge of the Principal Shareholders, no employee of Avtech has a
       present intention to leave the employ of Avtech or has taken any action
       directed towards leaving the employ of Avtech. Except as set forth on
       Schedule 2.2.26, to the knowledge of the Principal Shareholders, no
       former employee of Avtech is currently in or intends to enter into
       competition with the business of Avtech.
 
           2.2.27  CREDIT TERMS: PRODUCT WARRANTIES.  Adequate reserves have
       been made (and are reflected in the Delivered Financial Statements) for
       the aggregate amount of losses and expenses incurred by reason of
       allowances, customer dissatisfaction or liabilities arising under
       Avtech's warranties and guarantees during the three years ended September
       30, 1997; and there has been no material adverse change in that
       experience since said date. Except as set forth on Schedule 2.2.27, (i)
       there have been no recalls of Avtech product, (ii) to the best knowledge
       of the Principal Shareholders, there is no Avtech product which is either
       defective or likely to experience a failure rate materially greater than
       the average for Avtech's products over the three year period ended
       September 30, 1997, and (iii) Avtech has conducted all qualification
       inspections and quality conformance inspections required by the
       specifications for products of Avtech included on qualified products
       lists in material compliance with the requirements of such
       specifications, and all products shipped have been in material
       conformance with such specifications. Except as set forth and explained
       on Schedule 2.2.27, there have been no material departures from the
       standard terms and conditions of credit, discounts and warranties given
       by Avtech to its customers; and all of such standard terms and conditions
       are set forth on such schedule.
 
           2.2.28  CONTRACTS WITH AFFILIATES.  Any contract, commitment, lease,
       permit or other instrument, agreement, understanding or obligation (each
       a "Commitment") between Avtech and any affiliate (including each
       Shareholder), is the equivalent of an "arms-length" transaction with a
       third party, and each such Commitment is described on Schedule 2.2.28
       hereto.
 
           2.2.29  GOVERNMENT CONTRACTS.  Except as set forth on Schedule
       2.2.29, Avtech is not a party to, nor is it bound by, nor does it have
       any liability with respect to, any Government Contracts and has not
       submitted any bid with respect thereto, which has not expired. For
       purposes of this Section 2.2.29, the term "Government" means any agency,
       division, subdivision, audit group, or procuring office of the federal
       government, including the employees or agents thereof; the term
       "Transferor" means Avtech and its subsidiaries, divisions, affiliates,
       joint venturers, agents, employees, officers and directors; the term
       "Government Contract" means any prime contract, subcontract, basic
       ordering agreement, letter contract, purchase order or delivery order of
       any kind, including all amendments, modifications and options thereunder
       or relating thereto, between Transferor and any of a Government, any
       prime contractor of a Government, any subcontractor of such a prime
       contractor or any subcontractor of another subcontractor, however far
       removed from the prime contractor such subcontractor may be, (A)
       currently in force;
 
                                       13
<PAGE>
       (B) which, within the three years preceding the date of this Agreement,
       expired or were terminated; or (C) for which final payment was received
       within the three years preceding the date of this Agreement; and the term
       "Bid" means any outstanding quotation, bid or proposal submitted by
       Transferor to a Government, any proposed prime contractor of a
       Government, or any proposed subcontractor.
 
           2.2.30  EXCLUSIVE SELLING ARRANGEMENTS; STRATEGIC ALLIANCES.  Except
       as disclosed in Schedule 2.2.30, (i) Avtech has entered into no exclusive
       selling arrangements, and (ii) no agreement or understanding has been
       entered into, proposed, or regardless of commencement date, is in force
       between Avtech and any company which is an arrangement with any other
       person which involves equity investment or ownership, a joint venture or
       revenue or profit sharing (herein, a "Strategic Alliance"). An
       arrangement for a preferred supplier relationship which does not have any
       of the characteristics described in the foregoing sentence is not a

        3.1  COVENANTS OF THE SHAREHOLDERS.
 
           3.1.1  COVENANT AGAINST DISCLOSURE.  Other than in the ordinary
       course of business of Avtech and except for professional advisors

       Shareholders agree not to (a) disclose to any person, association, firm,
       corporation or other entity (other than DAH or those designated in
       writing by DAH) in any manner, directly or indirectly, any information or
       data relevant to the business of Avtech, whether of a technical or
       commercial nature, or (b) use, permit or assist, by acquiescence or
       otherwise, any person, association, firm, corporation or other entity
       (other than DAH or those designated in writing by DAH) to use, in

<PAGE>
       any manner, directly or indirectly, any such information or data,
       excepting only use of such data or information as is at the time
       generally known to the public and which did not become generally known
       through any breach of any provision of this Section 4.2.2.

           3.1.3  INJUNCTIVE RELIEF.  Each of the Principal Shareholders
       acknowledges and agrees that DAH's remedy at law for any breach of any of
       such Shareholders' obligations under Subsections 3.1.1 and 3.1.2 hereof
       would be inadequate, and agrees and consents that temporary and permanent
       injunctive relief may be granted in a proceeding which may be brought to
       enforce any such provision without the necessity of proof of actual
       damage. The rights and remedies conferred upon DAH under this Section, or
       by any instrument or law, shall be cumulative and may be exercised
       singularly or concurrently.
 
           3.1.4  CONDUCT OF BUSINESS OF AVTECH PRIOR TO CLOSING DATE.  Each of

           (e) The Principal Shareholders shall not, directly or indirectly,
       solicit or encourage (including by way of furnishing any non-public
       information concerning the business, properties or assets of Avtech), or
       enter into any negotiations or discussions concerning, any Acquisition
       Proposal (as defined below). Any Shareholder will notify DAH promptly by

           5.2.2  PAYMENT.  DAH shall have made the payments required pursuant
       to Section 1.2.1 and 1.2.2.
 
           5.2.3  HART SCOTT RODINO.  Prior to the Closing Date, (i) DAH shall
       have timely made all filings, submissions and responses which it is
       required to make, or in DAH's reasonable judgment are desirable, in
       connection with the transactions contemplated herein pursuant to the
       Hart-Scott-Rodino Act, and (ii) all waiting periods applicable under such
       Act shall have been terminated.
 
           5.2.4  ESOT MATTERS.  The ESOT Trustee shall be independent of all
       other parties to this Agreement and shall have relied, in making its
       decision whether to enter into this Agreement on behalf of the ESOT, on
       the written report of an appraiser who is qualified to value the Stock
       and is unrelated to Avtech or any of the parties to this Agreement. The
       appraiser's report will be delivered in draft not less than one week
       prior to the Closing Date and shall be issued and delivered on the
       Closing Date, and which will set forth the appraiser's qualifications,
       its determination of the value of the Stock as of the Closing Date and
       the factors and methodologies used by the appraiser in making the
       appraisal. For purposes of this Section, the Trustee shall be considered
       independent of all other parties to this Agreement if it is a bank,
       within the meaning of Code Section 581, which is not: (1) directly or
       indirectly, through one or more intermediaries, controlling, controlled
       by, or under common control with any of the other parties to this
       Agreement; (2) a partner or employer of any such party; or (3) a
       corporation or partnership of which any such party is an officer,
       director or partner.
 
           5.2.5  FAIRNESS OPINION.  The ESOT Trustee shall have received, in a
       form acceptable to the ESOT Trustee, the opinion of the financial advisor
       to the ESOT that:
 
               (a) The ESOT is receiving "adequate consideration" (as that term
           is defined in the ERISA) for the shares transferred to DAH under the
           terms of the "Agreement"; and
 
               (b) The terms of the transaction described in the Agreement, the
           Escrow Agreement and Joint Instructions are fair to the ESOT from a
           financial point of view.
 
    A full report of the financial advisor's opinion shall be delivered as of
the Closing Date (or as soon as before such Closing Date as practical). Such
report shall document the factors and methodology utilized by the financial
advisor in rendering the opinion. The report shall also set forth the financial
advisor's qualifications to render such an opinion of value and fairness.
 
    6.  MISCELLANEOUS PROVISIONS.

        1.2  NON-ASSIGNMENT OF ASSETS.  To the extent that any Asset described
    in Section 1.1 may not be assigned or may only be assigned with the consent
    of a third party, then, notwithstanding anything to the contrary in this
    Agreement, neither this Agreement nor any action taken shall constitute an
    assignment or an agreement to assign such Asset; PROVIDED, HOWEVER, that in
    such case Dettmers will use its best efforts to obtain the consent of such
    party to the assignment to Buyer. If such consent is not obtained, Dettmers
    shall provide to Buyer the benefits of such Asset or a comparable asset in
    its place as a condition to the obligations of DAH and Buyer hereunder.
 
    2.  PURCHASE PRICE.  The price for the Assets (the "Purchase Price"), shall
be the amount determined pursuant to this Section 2 payable to Dettmers, or its
permitted assigns, as follows:
 
        2.1    Subject to adjustment as provided in Section 2.2, $2,200,000 of
    the Purchase Price shall be payable as follows: (i) $100,000 shall be paid
    in immediately available funds upon the execution of this Purchase
    Agreement; and (ii) $2,100,000 shall be paid in immediately available funds
    on the first business day on or after June 29, 1998 after all conditions in
    Section 6.2 have been satisfied or waived (which date is estimated to be
    June 30, 1998), (the actual date is referred to as the "Closing Date").
 
        2.2    The $2,100,000 amount payable on the Closing Date under Section
    2.1 is subject to reduction as follows: (a) to the extent that the Assets
    are encumbered by indebtedness or other liens (other than accounts payable
    to trade creditors for goods and services incurred in the ordinary course of
    Dettmers' business and consistent with Dettmers' current practices for
    payment of trade creditors), the payment shall be reduced by the aggregate
    value of such indebtedness or liens; and (b) to the extent that
    shareholders' equity in Dettmers at the Closing Date is less than
    shareholders' equity reported on the December 31, 1997 preliminary balance
    sheet of Dettmers previously delivered to DAH, the payment shall be reduced
    in a corresponding amount.
 
        2.3    On March 31 of each of the years 2000, 2001, 2002 and 2003, DAH
    shall pay an additional $500,000, IF as of such date the Attributed EBITDA
    (as defined below) for the year ended the prior December 31 is not less than
    $650,000 (for 1999), $800,000 (for 2000), $1,000,000 (for 2001) and
    $1,200,000 (for 2002). To the extent that the Attributed EBITDA for any such
    year is less than the foregoing target amounts specified, but exceeds 90% of
    such amount, Dettmers shall be paid a PRO RATA portion of the amount so
    specified for such year. No payment shall be made in respect of any such
    year for which the Attributed EBITDA is equal to or less than 90% of the
    foregoing target amounts. The payments contemplated by this Section 2.3 are
    not contingent on the continued employment of the Dettmers Shareholders by
    Buyer.
 
        As used herein the term "EBITDA" means 'Earnings 'Before Interest and
    Tax ("EBIT"), adding back to EBIT, (i) Depreciation, and (ii) Amortization
    (including without limitation all amortization of intangibles related to the
    acquisition of the Assets and all financing costs of the acquisition of the
    Assets). In determining EBITDA, no management fee or other charge shall be
    imposed by DAH. As used herein "Attributed EBITDA" means for any calendar
    year listed in Section 2.3, the EBITDA attributable to the Assets and
    included in the consolidated income statement of DAH for such year, which
    calculation shall be reviewed by the independent certified public accountant
    which renders the opinion on the financial statement of DAH for such year.
    The terms EBIT, Depreciation and Amortization are as defined in GAAP.
 
        In the event DAH requires the operations of Buyer after the Closing to
    undertake a project which, as a result of the lead time between R&D
    expenditure and expected revenue, will have a material adverse impact on
    EBITDA, the parties shall negotiate in good faith until they have reached an
    agreement with respect to a credit, if any, to the calculation EBITDA for
    the payments to be made pursuant to this Section 2.3.
 
        DAH and the Buyer shall record the purchase of the Property as net
    assets including goodwill.

       material Permits. Each of such Permits is currently valid and in full
       force and effect and assignable to Buyer, and the closing of and the
       transactions contemplated by this Agreement will not result in the
       termination of any Permit. Such Permits listed on such schedule

       authorizations, approvals, and certificates of any regulatory,
       administrative or other agency or body necessary for the conduct of the

       trademark, copyright or other proprietary right of any third party.

           3.2.7  RESTRICTIVE DOCUMENTS OR LAWS.  With the exception of the
       matters listed on Schedule 3.2.7, Dettmers is not bound under any (and,
       to Senior Management's Knowledge, there is no) pending, proposed or
       threatened regulation, certificate, mortgage, lien, lease, agreement,
       contract, instrument, law, vote, order, judgment or decree, or any
       similar restriction not of general application which materially restricts
       or otherwise adversely affects, or reasonably could be expected to

       of the transfers of the Assets to Buyer and the other transactions
       contemplated in this Agreement or (b) in any material respect: (i) the
       condition, financial or otherwise, of Dettmers or any material

<PAGE>
       part of the Assets; or (ii) the continued operation by Buyer of the
       business of Dettmers after the

           3.2.8  REAL PROPERTY.  Schedule 3.2.8 contains complete and accurate
       legal descriptions of each parcel of Real Property and a list of all Real

       other than as are listed on such schedule. The Real Property includes all
       such interests now owned or used by Dettmers and material to the
       operation of its business as presently conducted. All such properties are
       held free and clear of all mortgages, pledges, liens, security interests
       and encumbrances, and material restrictions of any nature whatsoever,

       operation of its business as presently conducted, is suitable for the
       purpose or purposes for which it is being used, and is in all material
       respects in such condition and repair as to permit the continued
       operation of said business. To Senior Management's Knowledge, none of
       such real property, buildings or structures is in need of maintenance or
       repairs except for ordinary, routine maintenance and repairs. To Senior
       Management's Knowledge, there are no material structural defects in the
       exterior walls or the interior bearing walls, the foundation or the roof
       of any plant, building, garage or other such structure owned, leased or
       used by Dettmers and the electrical, plumbing and heating systems, and
       the air conditioning system, if any, of any such plant, building, garage
       or structure are in reasonable operating condition in light of their age
       and prior use. To Senior Management's Knowledge, the utilities servicing
       the real property owned, leased or used by Dettmers are adequate to
       permit the continued operation of the business of Dettmers and to Senior
       Management's Knowledge, there are no pending zoning, condemnation or
       eminent domain proceedings, building, utility or other moratoria, or
       injunctions or court orders which would materially effect such continued
       operation. Schedule 3.2.8 lists, and Dettmers has furnished or made
       available to Buyer copies of, all engineering, geologic and environmental
       reports prepared by or for Dettmers with respect to the real property
       owned, leased or used by Dettmers.
 
           3.2.9  PERSONAL PROPERTY.  Schedule 3.2.9 contains complete and
       accurate descriptions of, Dettmers' Machinery, Equipment, Tooling and

       which is personal property of every kind, nature and description,
       tangible or intangible, and wherever located, including all property and
       assets which are personal property shown or reflected on the March 31,
       1998 Balance Sheet. Schedule 3.2.9 contains a complete and accurate
       description of all Personal Property Leases to which Dettmers is party or
       which Dettmers uses in its business. The Property which is personal
       property constitutes all material personal property now used in and
       necessary for the conduct of the business of Dettmers as presently
       conducted, all of which is held free and clear of all mortgages, pledges,
       liens, security interests, encumbrances and material restrictions of any
       nature whatsoever, except as listed on Schedule 3.2.9.
 
           Except as listed on Schedule 3.2.9, no financing statement under the
       Uniform Commercial Code or similar law naming Dettmers as debtor has been
       filed in any jurisdiction, and Dettmers is not a party to or bound under
       any agreement or legal obligation authorizing any party to file any such
       financing statement. Except as set forth on Schedule 3.2.9, all Machinery
       and Equipment and other tangible personal property owned or used by
       Dettmers and material to the operation of the business as presently
       conducted is suitable for the purpose or purposes for which it is being
       used, and is in all material respects in such condition and repair as to
       permit the continued operation of said business. None of the Machinery or
       Equipment is in need of maintenance or
 
                                       7
<PAGE>
       repairs in any material respect except for ordinary, routine maintenance
       and repairs necessary to permit the operation of said business.
 
           3.2.10  ENVIRONMENTAL MATTERS.  Except as set forth on Schedule
       3.2.10, the operations of Dettmers meet the requirements of all
       occupational health and safety acts and all environmental laws and
       regulations of all federal, state and local governmental or regulatory
       bodies having jurisdiction over Dettmers. Without limiting the generality
       of the foregoing, and by way of example only, except as set forth on
       Schedule 3.2.10:
 
           (a) There has not been, and is not occurring, any Release of any
       Hazardous Substance on any real property owned, operated, leased or used
       by Dettmers. For purposes of this Agreement, the terms "Release" and
       "Hazardous Substance" shall have the same meanings as those terms are
       given in the Comprehensive Environmental Response, Compensation and
       Liability Act of 1980, 42 U.S.C. Section 9601 ET SEQ. ("CERCLA"), except
       that for purposes of this Agreement petroleum (including crude oil or any
       fraction thereof) shall be deemed a Hazardous Substance.
 
           (b) Dettmers has not ever sent a Hazardous Substance to a site which,
       pursuant to CERCLA or any similar state law, (A) has been placed, (or to
       Senior Management's Knowledge, is proposed to be placed, or may in the
       future be placed,) on the "National Priorities List" of hazardous waste
       sites or on any similar list of any federal, state or local governmental
       agency, including the Comprehensive Environmental Response, Compensation
       and Liability System list for potential hazardous waste sites, or (B) is
       subject to a claim, an administrative order or other request to take
       "removal" or "remedial" action (as defined under CERCLA) or to pay for
       any costs relating to such site.
 
           (c) Dettmers has not ever been or is currently in violation of any
       provision of the Toxic Substances Control Act or the regulations
       promulgated thereunder.
 
           (d) Dettmers is not involved in any suit or has received notice of
       any claim relating to personal injuries from exposure to Hazardous
       Substances.
 
           3.2.11  BROKERS, FINDERS.  Except as disclosed on Schedule 3.2.11,
       (a) the transactions contemplated herein were not submitted to Dettmers
       nor any of its officers, directors, employees or Shareholders or their
       respective agents (the "Selling Parties") by any broker or other person
       entitled to a commission or finder's fee thereon, and were not with the
       consent of the Selling Parties submitted to DAH by any such broker or
       other person; (b) none of the Selling Parties has engaged any broker or
       finder or incurred or taken any action which may give rise to any
       liability against Dettmers or the Property for any brokerage fees,
       commissions, finders fees or similar fees or expenses, and no broker or
       finder has acted directly or indirectly for the Selling Parties in
       connection with this Agreement or the transactions contemplated hereby;
       and (c) no investment banking, financial advisory or similar fees have
       been incurred or are or will be payable by the Selling Parties in
       connection with this Agreement or the transactions contemplated hereby.
       All of such fees, commissions or other liabilities incurred by any of the
       Selling Parties in connection with the transactions contemplated hereby
       shall be the sole responsibility of the Dettmers Shareholders; and none
       of the Assets of Dettmers have been or shall be applied to pay the same.
 
           3.2.12  LEGAL PROCEEDINGS, ETC.  Except as set forth on Schedule
       3.2.12, there is no claim, litigation, action, suit or proceeding,
       administrative or judicial, filed, pending, or to Senior Management's
       Knowledge, threatened against Dettmers, or involving the Assets, this
       Agreement or the transactions contemplated hereby, at law or in equity,
       before any federal, state or local court or regulatory agency, or other
       governmental authority, including any unfair labor practice or grievance,
       proceedings or claim, which although disclosed on Schedule 3.1.12 would
       have a material adverse effect on the business or assets of Dettmers. To
       Senior Management's knowledge, there is no basis upon which such claim,
       litigation, action, suit or proceeding would
 
                                       8
<PAGE>
       reasonably be brought or initiated. Except as set forth in Schedule
       3.2.12, Dettmers is not subject to any judgment, order or decree, or, to
       Senior Management's Knowledge, any governmental restriction applicable to
       Dettmers which has a reasonable probability of having a Material Adverse
       Effect. As used herein, "Material Adverse Effect" means any material
       adverse change in the business operations (as presently conducted or
       proposed to be conducted), assets, properties or rights, prospects or
       condition (financial or otherwise) of Dettmers, or any occurrence,
       circumstance, or combination thereof which reasonably could be expected
       to result in any such material adverse change, or which materially
       adversely affects the ability of Dettmers to conduct business in any
       area, or of Buyer to continue the business of Dettmers as presently
       conducted.
 
           3.2.13  NO CONFLICT OR DEFAULT.  Neither the execution and delivery
       of this Agreement or any other Transaction Document, nor compliance with
       the terms and provisions hereof or thereof, including the consummation of
       the transactions contemplated hereby and thereby, will (a) violate in any
       material respect any statute, regulation or ordinance of any governmental
       authority, or (b) conflict with or result in the breach of any term,
       condition or provision of the articles of incorporation or bylaws of
       Dettmers, or (c) to Senior Management's Knowledge, conflict with or
       result in the breach of any term, condition or provision of any
       agreement, deed, contract, mortgage, indenture, writ, order, decree,
       legal obligation or instrument, to which Dettmers is a party or by which
       such party or any part of the Assets are or may be bound, or (d)
       constitute a material default (or an event which with the lapse of time
       or the giving of notice, or both, would constitute a material default)
       under any such agreement, deed, contract, mortgage, indenture, writ,
       order, decree, legal obligation or instrument thereunder, or (e) result
       in the creation or imposition of any material lien, charge or
       encumbrance, or to Senior Management's Knowledge, any other material
       restriction of any nature whatsoever with respect to any part of the
       Property, or (f) give to others any interest or rights, including rights
       of termination, acceleration or cancellation in or with respect to any
       part of the Property or the business of Dettmers which would have a
       Material Adverse Effect thereon.
 
           3.2.14  LABOR RELATIONS.  Schedule 3.2.14 sets forth all collective
       bargaining or other labor agreements to which Dettmers is bound and which
       covers Dettmers employees. Dettmers has previously delivered to Buyer
       true, correct and complete copies of each such agreement. There is no
       labor strike, dispute, slowdown or stoppage, or petition for
       certification actually pending or, to Senior Management's Knowledge,
       threatened against or involving Dettmers, nor, to Senior Management's
       Knowledge, any union organizing campaign pending or threatened. Schedule
       3.2.14 sets forth all pending grievances and arbitration proceedings
       against Dettmers arising out of or under a collective bargaining or other
       labor agreement. No collective bargaining or other labor agreement is
       currently being negotiated by or on behalf of Dettmers. With respect to
       the business of Dettmers, Dettmers has not experienced any work stoppage
       or other material labor difficulty over the past three years. Except for
       the employment contract with Pam Courtnery there is no obligation of
       Dettmers to any employee or any person employed by Staff Leasing assigned
       to Dettmers except for an "at will" relationship. No agreement which is
       binding on Dettmers restricts it from relocating or closing any or all of
       its operations.
 
           3.2.15  EMPLOYEE BENEFIT PLANS.
 
           (a) Except as set forth in Schedule 3.2.15, Dettmers does not
       currently sponsor, maintain or contribute to, nor within the past 3 years
       sponsored, maintained or contributed to, any pension, retirement,
       profit-sharing, deferred compensation, bonus, stock option or other
       incentive plan, or any other employee benefit program, arrangement,
       agreement or understanding, or medical, vision, dental or other health
       plan, or life insurance or disability plan, or any other employee benefit
       plan as defined in Section 3(3) of the Employee Retirement Income
       Security Act of 1974, as amended ("ERISA"), whether or not any such
       employee benefit plan is otherwise exempt from the provisions of ERISA,
       and whether or not formal or informal, written or oral, and whether or
 
                                       9
<PAGE>
       not legally binding. All such plans are fully funded through the date of
       this Agreement or amounts sufficient to fully fund contributions to such
       plans through the Closing Date are reserved for in the March 31, 1998
       Financial Statements. All such plans, funds or programs sponsored,
       maintained or contributed to by Dettmers currently or within the past 3
       years, whether or not listed on Schedule 3.2.15, are hereinafter referred
       to as the "Employee Benefit Plans"). For the purpose of this Section
       3.2.15, the term "Dettmers" shall include all "entities" of Dettmers,
       whether or not incorporated, with which it would be treated as a single
       employer for purposes of Sections 414(b), (c) or (m) of the Internal
       Revenue Code (the "Code").
 
           (b) As of the Closing Date, no entity that may be regarded as under
       common control with Dettmers pursuant to Section 414 of the Code shall
       have incurred any unsatisfied liability under Title IV of ERISA or
       Section 4980 of the Code, nor shall any such entity have become subject
       to a lien pursuant to Section 412(n) of the Code.
 
           (c) Full payment has been made of all amounts which Dettmers is
       required, under applicable law or under any Employee Benefit Plan or any
       agreement relating to any Employee Benefit Plan to which it is a party,
       to have paid as contributions to, or benefits under, any Employee Benefit
       Plan as of the last day of the most recent fiscal year of such Employee
       Benefit Plan ended prior to the date hereof. Dettmers has made adequate
       provision in its financial statements for liabilities to meet current
       contributions or benefit payments.
 
           (d) Dettmers has performed all obligations required to be performed
       by it under the Employee Benefit Plans. Dettmers has not engaged in any
       transaction with respect to the Employee Benefit Plans which would
       subject it, Buyer or DAH to a tax, penalty or liability for a prohibited
       transaction under section 406, 407 or 502(i) of ERISA or Section 4975 of
       the Code, nor have any of Dettmers' directors, officers, partners,
       employees or agents, to the extent they or any of them are fiduciaries
       with respect to such Employee Benefit Plans, breached any of their
       responsibilities or obligations imposed upon fiduciaries under Title I of
       ERISA or which would result in any claim being made under or by or on
       behalf of any such Employee Benefit Plans by any party with standing to
       make such claim. Dettmers will not have any plan or commitment, whether
       formal or informal, written or oral, and whether or not legally binding,
       to modify or change any Employee Benefit Plan in any material manner
       prior to the Closing Date. Dettmers and any "administrator(s)" (as
       described in Section 3(16)(A) of ERISA) of the Employee Benefits Plans
       have complied in all material respects with the applicable requirements
       of ERISA, the Code and all other statutes, orders, rules or regulations,
       specifically including material compliance with all reporting and
       disclosure requirements of Part 1 of Title 1 of ERISA and of the Code in
       a timely and accurate manner, and no penalties have been or will be
       imposed, nor is Dettmers or any administrator liable for any penalties
       imposed, under ERISA, the Code or otherwise with respect to the Employee
       Benefit Plans or any related trusts. Dettmers is not delinquent in the
       payment of any federal, state or local taxes with respect to the Employee
       Benefit Plans. There is no pending litigation, arbitration, or disputed
       claim, settlement adjudication or proceeding with respect to the Employee
       Benefit Plans, and neither Dettmers nor any administrator is aware of any
       threatened litigation, arbitration or disputed claim, adjudication
       proceeding, or any governmental or other proceeding, or investigation
       with respect to the Employee Benefit Plans or with respect to any
       fiduciary or administrator thereof (in their capacities as such), or any
       party-in-interest thereto (with respect to their relationship as such).
       There is no "defined benefit plan" within the meaning of Section 414(j)
       of the Code or Section 3(35) of ERISA to which Dettmers has been a party
       or has been required to make any contributions at any time during the
       last ten years. There is no "multiemployer plan" within the meaning of
       Section 3(37) of ERISA to which Dettmers has been a party or has been
       required to make any contributions at any time during the last ten years.
 
                                       10
<PAGE>
           (e) Dettmers has delivered or caused to be delivered to Buyer and DAH
       prior to the Closing, true, accurate and complete copies of (A) all
       Employee Benefit Plans and any related trust agreements, custodial
       agreements, investment management agreements, insurance contracts or
       policies, and administrative service contracts, all as in effect,
       together with all amendments thereto which will become effective at a
       later date; (B) the latest Summary Plan Description and any modifications
       thereto for each Employee Benefit Plan requiring same under ERISA; (C)
       the Summary Annual Report for the current and prior fiscal years for each
       Employee Benefit Plan requiring same under ERISA; (D) each Form 5500
       and/or Form 990 series filing (including required schedules and financial
       statements) for the current and prior fiscal years for each Employee
       Benefit Plan required to file such form; and (E) the most recent
       actuarial evaluation, analysis or other report issued with respect to any
       Employee Benefit Plan. Neither Dettmers nor any officer, partner,
       employee, representative or agent of Dettmers has made any written or
       oral representations or statements to any current or former employees,
       dependents, participants or beneficiaries or other persons which are
       inconsistent in any material manner with the provisions of these
       documents.
 
           (f) With respect to any of Dettmers' employee welfare plans (as
       defined in Section 3(1) of ERISA and including those Employee Benefits
       Plans which qualify as such) which are "group health plans" under Section
       4980B of the Code and Section 607(1) of ERISA and related regulations
       (relating to the benefit continuation rights imposed by the Consolidated
       Omnibus Budget Reconciliation Act of 1986 ("COBRA"), as amended to date),
       there has been timely compliance in all material respects with all
       requirements imposed thereunder, as and when applicable to such plans, so
       that Dettmers has not (nor will incur any) loss, assessment, penalty,
       loss of federal income tax deduction or other sanction, arising on
       account of or in respect of any failure to comply with any COBRA benefit
       continuation requirement, which is capable of being assessed or asserted
       directly or indirectly against such party, or against Buyer or DAH or any
       of their respective subsidiaries or other member of Buyer's corporate
       control group, with respect to any such plan. Dettmers has no obligation
       to provide medical benefits to any former employee, except as required by
       COBRA.
 
           (g) No Employee Benefit Plan maintained by Dettmers which is a
       "welfare plan" within the meaning of Section 3(1) of ERISA provides
       benefits to employees after termination of employment, except as required
       by Section 4980B of the Code.
 
           3.2.16  CONTRACTS AND COMMITMENTS.  Schedule 3.2.16 is a list of all
       of the Contracts to which Dettmers is a party and which involve the
       payment by or to Dettmers in the aggregate of $50,000 or more (per
       contract) during any year. Dettmers has previously delivered to Buyer
       correct and complete copies of each such Contract. The Real Property
       Leases, the Personal Property Leases and the Contracts listed on Schedule
       3.2.16, taken together, constitute all of the contracts, agreements,
       contract rights, leases, license agreements, franchise rights and
       agreements, policies, purchase and sales orders, quotations and executory
       commitments, instruments, guaranties, indemnifications, arrangements,
       obligations and understandings (written or oral), involving the payment
       by or to Dettmers, in the aggregate of $50,000 or more (per contract)
       during any year, necessary to the conduct of the business of Dettmers as
       presently conducted.
 
           All of the Real Property Leases, the Personal Property Leases and the
       Contracts are valid and binding, in full force and effect and enforceable
       against Dettmers in accordance with their respective provisions. Dettmers
       has not assigned, mortgaged, pledged, encumbered, or otherwise
       hypothecated any of its right, title or interest under any Real Property
       Lease, any Personal Property Lease, or any Contract. Neither Dettmers
       nor, to Senior Management's Knowledge, any other party thereto is in
       material violation of, in default in respect of, nor has there occurred
       an event or condition which, with the passage of time of giving of notice
       (or both) would constitute a material violation or default of, any Real
       Property Lease, any Personal Property Lease, or any
 
                                       11
<PAGE>
       Contract, and, to Senior Management's Knowledge, there are no facts or
       circumstances which would reasonably indicate that Dettmers (or any other
       party) will be or may be in material violation of or in default in
       respect of any Real Property Lease, any Personal Property Lease, or any
       Contract, subsequent to the date hereof. Without limiting the foregoing,
       no consents, authorizations, approvals or similar agreements or
       acquiescence is required from any party under any Contract, Real Property
       Lease or Personal Property Lease to any of the transactions contemplated
       hereby, except to the extent listed on Schedule 3.2.16 hereof, and each
       of such consents will be delivered to DAH on the Closing Date. No notice
       has been received by Dettmers claiming any such default or indicating the
       desire or intention of any other party thereto to amend, modify, rescind
       or terminate the same to the extent that it would have a Material Adverse
       Effect on the business or assets of Dettmers.
 
           3.2.17  ACCOUNTS RECEIVABLE, ETC..  All of the Receivables of
       Dettmers are set forth on Schedule 3.2.17, together with the value
       thereof. All such Receivables and Prepaid Expenses, together with any
       additional Receivables and Prepaid Expenses arising between the date
       hereof and the Closing Date (in each case net only of such allowances for
       doubtful accounts as are disclosed on the March 31, 1998 Balance Sheet),
       (a) are or will be valid and subsisting, (b) represent or will represent
       sales actually made, (c) arose or will arise in the ordinary and usual
       course of the business of Dettmers, (d) except as set forth on Schedule
       3.2.17, to the extent not collected prior to the Closing Date, will be
       due and enforceable according to their terms within 90 days after the
       date of the initial invoice therefor, and (e) are not and (except as may
       be caused by Buyer) will not be subject to any material counterclaim,
       set-off, defense, lien, charge or encumbrance of any nature. There has
       not been any material adverse change in the collectibility of the
       Receivables of Dettmers since March 31, 1998. Buyer will use diligent
       efforts to collect the Receivables.
 
           3.2.18  INVENTORIES.  Schedule 3.2.18 completely and accurately lists
       all raw materials, supplies, parts, work-in-process, and finished goods
       inventory and other inventory owned by Dettmers and the accurate cost of
       such inventory as of March 31, 1998. Except as set forth in Schedule
       3.2.18 and except for amounts which in the aggregate are not material,
       all such inventories (i) consist of a quality and quantity usable and
       saleable in the ordinary and usual course of business, except for items
       of obsolete materials and materials of substandard quality, all of which
       have been written off or written down on the books of Dettmers to net
       realizable value prior to March 31, 1998 and (ii) have been priced at the
       lower of cost or market on a FIFO basis. The quantities of all material
       portions of each type of inventory (whether raw materials, work-in-
       process, or finished goods) are not excessive, but are reasonable and
       warranted in the present circumstances of Dettmers; and all material
       portions of work-in-process and finished goods inventory is free of any
       material defect or other deficiency.
 
           3.2.19  BACKLOG.  All unfilled orders to purchase goods and services
       of Dettmers are set forth in Schedule 3.2.19 and are firm and binding
       commitments (subject to cancellation rights set forth therein) of the
       respective purchasers (assuming that each such purchaser has properly
       authorized the same by all requisite acts and has properly executed and
       delivered a purchase order, which assumption, to Senior Management's
       Knowledge, is the case) to purchase the goods or services indicated.
 
           3.2.20  BOOKS OF ACCOUNT: RECORDS.  Except for the qualifications (if
       any) explicitly set forth therein or in Schedule 3.2.20 the general
       ledgers, books of account and other financial records of Dettmers are
       complete and correct, have been maintained in accordance with good
       business practices, and the matters contained therein are appropriately
       and accurately reflected in the Financial Statements.

           3.2.21  MANAGERS, EMPLOYEES AND COMPENSATION.  Schedule 3.2.21 sets
       forth the name of all managers and engineers of Dettmers, their
       respective terms of office, the total salary, bonus payments, fringe
       benefits and perquisites each received in each of the calendar years
       ending December 31, 1995, 1996 and 1997 (or, if briefer, during their
       tenure of employment with Dettmers and any affiliate thereof), and
       changes to the foregoing which have occurred since December 31, 1997,
       together with the professional background of each manager and engineer
       for the last 5 years (as disclosed to Dettmers by such employee and, to
       Senior Management's Knowledge, correctly and completely); such Schedule
       also lists and describes the current base salary, bonus payments, fringe
       benefits and perquisites of any other employee, agent or representative
       of Dettmers whose total current salary, bonus or other compensation
       exceeds $50,000 annually during any of the calendar years ending December
       31, 1995, 1996 or 1997, and changes to the foregoing since December 31,
       1997. There are no other material forms of compensation paid to any such
       director, officer or employee of Dettmers. The provisions for wages and
       salaries accrued on the March 31, 1998 Balance Sheet are adequate for
       salaries and wages, including accrued vacation pay, for the period up
       through the date thereof, and Dettmers has accrued on its books and
       records all obligations to pay wages and salaries and other compensation
       to its employees, including, but not limited to, vacation pay and sick
       pay, and all commissions and other fees payable to agents, salesmen and
       representatives. Dettmers has filed any and all payroll tax returns, and
       paid all payroll taxes due for any and all employees due through the
       Closing Date.
 
           Except as set forth on Schedule 3.2.21, Dettmers has not become
       obligated, directly or indirectly, to any shareholder, director, officer
       or partner of Dettmers or any member of their families, except for
       current liability for employment compensation. Except as set forth on
       Schedule 3.2.21, no shareholder, director, officer, partner, agent or
       employee of Dettmers holds any position or office with or has any
       financial interest, direct or indirect, in any supplier, customer or
       account of, or other outside business which has transactions with
       Dettmers. Neither Dettmers nor, to Senior Management's Knowledge, any
       third party, has taken any action with respect to any shareholder,
       director, officer, partner, employee or representative of Dettmers to
       attempt to induce or which would influence any such person not to become
       associated with Buyer from and after the Closing Date or from serving
       Buyer in a capacity similar to the capacity presently held. Except to the
       extent as may have been previously disclosed to DAH by Dettmers in
       writing, no employee of Dettmers, to Senior Management's knowledge, has a
       present intention to leave the employ of Dettmers or has taken any action
       directed towards leaving the employ of Dettmers. Except as set forth on
       Schedule 3.2.21, to Senior Management's Knowledge, no former officer or

       with the business of Dettmers.

       forth all of the standard terms and conditions of credit and discounts
       given by Dettmers to its customers in the usual and ordinary course of
       its business and a list of all transactions pending where there is a
       material departure therefrom. There has been no material change in the
       aggregate amount of losses and expenses incurred by reason of allowances,
       customer dissatisfaction or liabilities arising under Dettmers's
       warranties and guarantees during the three years ended December 31, 1997;
       and there has been no material adverse change in that experience since
       said date. Except as set forth on Schedule 3.2.22(b), (i) there have been
       no recalls of Dettmers product, (ii) to the knowledge of Senior
       Management, there is no Dettmers product which is either defective or
       likely to experience a failure rate materially greater than the average
       for Dettmers' products over the three year period ended December 31,
       1997, and (iii) Dettmers has conducted all qualification inspections and
       quality conformance inspections required by the specifications for
       products of Dettmers included on qualified products lists in material
       compliance with the requirements of such specifications, and all products
       shipped have been in material conformance with such specifications.

                         CONSENT AND AMENDMENT NO. 3 TO
                          LOAN AND SECURITY AGREEMENT
 
    This Consent and Amendment No. 3 to Loan and Security Agreement (this
"Amendment") is made as of May 29, 1998, among DeCrane Aircraft Holdings, Inc.,
a Delaware corporation ("Borrower"), Bank of America National Trust and Savings
Association, successor-by-merger to Bank of America Illinois, individually as a
lender ("BoA") and as agent ("Agent"), Comerica Bank--California ("Comerica"),
Mellon Bank, N.A. ("Mellon"), and Sumitomo Bank of California ("Sumitomo";
Sumitomo, BoA, Comerica and Mellon being collectively referred to as "Lenders").
 
    Reference is made to that certain Loan and Security Agreement dated as of
April 15, 1997 among Borrower, Agent and Lenders (as amended or otherwise
modified from time to time, the "Loan Agreement"; capitalized terms used herein

Agreement).
 
    Borrower has requested that Requisite Lenders consent to the acquisition
(the "Avtech Acquisition") by Borrower of not less than 99.44% of the
outstanding capital stock of Avtech Corporation, a Washington corporation

Avtech Acquisition would cause a breach of each of SECTIONS 5.11 and 5.17 of the
Loan Agreement.

Agreement in certain respects.
 
    NOW, THEREFORE, Agent, Lenders and Borrower agree as follows:
 
    1.  CONSENT.  Subject to the conditions precedent set forth in Section 2 of
this Amendment, Lenders hereby consent to the consummation of the Avtech
Acquisition. This consent shall not constitute (a) a modification or alteration
of the terms, conditions or covenants of the Loan Agreement or any document
entered into in connection therewith, or (b) a waiver, release or limitation
upon the exercise by Agent or any Lender of any of its rights, legal or
equitable, hereunder. Except as set forth above, Agent and each Lender reserves
any and all rights and remedies which it has had, has or may have under the Loan
Agreement.
 
    2.  AVTECH ACQUISITION CONDITIONS PRECEDENT.  The consent of the Lenders to

    of this Agreement;
 
        2.2. The terms of the Avtech Acquisition shall be no less favorable to
    the Borrower from those set forth in a draft Stock Purchase Agreement

    foregoing:
 
           2.2.1. The aggregate purchase price of the Avtech Acquisition shall

    Acquisition Documents") and (ii) a collateral assignment executed by the
    Borrower, in form and substance acceptable to Agent, of all representations,

    after giving effect to the Avtech Acquisition and the amendments set forth
    herein, together with such financial information as Requisite Lenders shall
    request to verify such compliance;

FOR IMMEDIATE RELEASE
 
JULY 1, 1998
 
          DECRANE AIRCRAFT HOLDINGS ACQUIRES DETTMERS INDUSTRIES INC.,
               DESIGNER AND MANUFACTURER OF CORPORATE JET SEATING
 
                            ACQUISITION HIGHLIGHTS:
 
    - STRENGTHENS PRODUCT OFFERINGS IN THE AIRCRAFT CABIN
 
    - INCREASES SALES TO EXISTING CLIENTS, INCLUDING DASSAULT/FALCON JET,
      BOMBARDIER AND THE MAJOR MODIFICATION CENTERS
 
    EL SEGUNDO, CA, JULY 1, 1998--DeCrane Aircraft Holdings, Inc. (NASDAQ:
DAHX), a leading manufacturer of avionics components and an avionics systems
integrator for the commercial and high-end corporate aircraft industry, today
announced the acquisition of Dettmers Industries Inc., a Florida-based
manufacturer of cabin interior products for the corporate jet market.
 
DETTMERS--KEY PLAYER IN CABIN INTERIORS
 
    Dettmers Industries designs, manufactures and markets seating and other
cabin interior products for the corporate aviation industry, particularly to
aircraft completion centers. Dettmers is a certified FAA manufacturing and
repair station, which expedites approvals and completion dates. Dettmers has
been growing revenues in excess of 30% annually for the last three years, said
DeCrane.
 
    "While several synergies have been identified in the sales and marketing
areas, the real attractiveness of the company is the potential for several new
seat designs that are currently coming to market. Therefore, the short-term
focus of the new subsidiary will be to qualify these new seat designs," said
DeCrane. "We believe the new motorized seat offered by Dettmers is among the
finest available, and has the potential to dominate the high-end executive
seating market for corporate jets," added DeCrane.
 
    "Dettmers has considerable expertise in making highly functional, motorized
seating products for the corporate jet market," said DeCrane. "The recently
obtained order for the executive seating on five new Boeing BBJ aircraft is
evidence of the company's evolving status as one of the premier providers of
executive seating products," said DeCrane.
 
    Dettmers sells its products to many of the same customers already serviced
by DeCrane, including Dassault, Bombardier and the major modification centers.
In addition to the obvious sales synergies, many of the products created by
DeCrane's Audio International and Avtech subsidiaries will be highly
complementary to Dettmers' product line, said DeCrane. Audio International
produces sound and cabin management systems, including in-flight entertainment
equipment, which is often housed in aircraft seating; Avtech makes audio,
lighting, power, communications and control equipment.
 
    Dettmers will operate as a separate subsidiary of DeCrane. President Andrew
Perl will report directly to Chuck Becker, DeCrane's President and Chief
Operational Officer. Co-founder and Vice President of
<PAGE>
Product Development Peter Dettmers will continue in his role as the chief
technology officer of the company.
 
FITS DECRANE'S KEY ACQUISITION CRITERIA
 
    DeCrane said he believes Dettmers' product line takes the company another
step forward by expanding the Company's product offerings for the high-end
corporate jet market to include seating and other cabinet interior products. The
industry is consolidating rapidly as the larger aircraft companies pare back the
number of vendors they are willing to buy from, thus simplifying their
purchasing operations. DeCrane is an industry leader in this consolidation
movement, acquiring companies that fit its acquisition criteria.
 
    Generally speaking, DeCrane seeks companies that provide synergy with the
existing product line or that give the company new capabilities. DeCrane's
product line is well balanced and is used throughout the lifecycle of an
aircraft (OEM, aftermarket and retrofit market).

Avtech Corporation
 
    In our opinion, the accompanying balance sheets and the related statements
of income, of stockholders' equity and of cash flows present fairly, in all
material respects, the financial position of Avtech Corporation at September 30,
1996 and 1997 and March 31, 1998, and the results of its operations and its cash
flows for each of the three years in the period ended September 30, 1997 and the
six months ended March 31, 1998, in conformity with generally accepted
accounting principles. 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 audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF THE COMPANY
 
    Avtech Corporation (the Company) is a custom design and manufacturing firm
established in 1963 to produce high-quality equipment for the aircraft industry.
In 1970, Avtech began to produce engineered products and has since focused its
engineering and product development efforts on responding to specifications from
original equipment aircraft manufacturers (OEMs). The Company's products fall
into five main categories:
 
1.  Aircraft communication control equipment (including audio control units,
    multiplexed audio systems and audio amplifiers).
 
2.  Aircraft lighting controls (including ballasts, dimmers and flood lighting).
 
3.  Power systems (including transformer rectifier units, power inverters and
    battery chargers).
 
4.  Airborne facsimile terminals (AvFax).
 
5.  Special products (including PDX intercoms, liquid-gauging and fill control,
    and frequency units).
 
FINANCIAL STATEMENT PRESENTATION
 
    The presentation 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 the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
    At September 30, 1996 and 1997 and March 31, 1998, the Company maintained
$549,000, $119,000 and $868,000 respectively, of its cash and cash equivalents
balances at one bank. At September 30, 1996 and 1997 and March 31, 1998, the
Company maintained $503,000, $4,017,000 and $2,392,000, respectively, in a money
market fund and bankers' acceptances.
 
RECEIVABLES AND CONCENTRATIONS OF CREDIT RISK
 
    Accounts receivable from trade customers are generally due within thirty
days. The Company performs periodic credit evaluations of its customers'
financial conditions and generally does not require collateral. All of the
Company's sales are to businesses directly associated with the aviation industry
(airlines, aircraft manufacturers, etc.). Approximately 70% of the Company's
sales are to customers based in the United States.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
PROPERTY AND EQUIPMENT
 
    The cost of property, plant and equipment is depreciated over the estimated
useful lives of the related assets. Depreciation is computed using the
straight-line and accelerated methods over the following estimated lives:

                                                                                        ---------

</TABLE>
 
    Maintenance and repairs are charged to operations when incurred. Additions
and improvements are capitalized. When property, plant and equipment are sold or
otherwise disposed of, the asset account and related accumulated depreciation
account are relieved, and any gain or loss is included in operations.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (determined by the first-in,
first-out method) or market. Costs of manufactured inventories include all
direct materials, labor and an allocation of overhead. Market represents the
lower of replacement cost or estimated net realizable value.
 
REVENUE RECOGNITION
 
    Revenues from the sale of manufactured products are recorded when shipped.
Reimbursements for nonrecurring engineering costs, which are expensed as
incurred, are included in revenues at the time a negotiated settlement is
reached with the customer. The Company's nonrecurring engineering revenues for
the years ended September 30, 1995, 1996 and 1997 and the six months ended March
31, 1998 were $1,257,000, $4,042,000, $527,000 and $138,000, respectively.
Included within accounts receivable at September 30, 1996 are $3,384,000 of
unbilled receivables which were collected in fiscal year 1997.
 
INCOME TAXES
 
    Deferred income taxes are determined using the liability method. A deferred
tax asset or liability is determined based on the difference between the
financial statement and tax basis of assets and liabilities as measured by the
enacted tax rates which will be in effect when these differences reverse.
Deferred tax expense is the result of changes in the asset and/or liability for
deferred taxes.
 
STOCK OPTION PLAN
 
    As permitted under Statement of Financial Accounting Standards No., 123,
"Accounting for Stock-Based Compensation" (SFAS 123), the Company measures
compensation expense related to the employee stock option plan utilizing the
intrinsic value method as prescribed by Accounting Principles Board No. 25,
"Accounting for Stock Issued to Employees".

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
ACCRUED WARRANTIES
 
    The Company sells a majority of its products to customers along with various
repair or replacement warranties. The terms of the warranties vary according to
the customer and/or the product involved. The most common warranty period is the
earlier of:
 
a.  36 months from the date of delivery to the operator, or;
 
b.  42 months from the date of manufacture
 
    Provisions for estimated future warranty costs are made in the period
corresponding to the sale of the product. Classification between short and
long-term warranty obligations is estimated based on historical trends.
 
UNAUDITED INTERIM RESULTS
 
    The financial information for the six months ended March 31, 1997 is
unaudited. In the opinion of the Company, the unaudited financial information is
presented on a basis consistent with the audited financial statements and
contains all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for such interim period. The
results of operations for the interim periods are not necessarily indicative of
results of operations for the full year.

NOTE 3 - PROPERTY AND EQUIPMENT
 
    The Company owns property located immediately adjacent to its main facility.
The property is not currently used for any rental or productive activity. In
1990, the property was condemned by the local authorities and is considered
unsuitable for habitation in its current state. The current carrying value of
$62,000 represents the original cost of the land and is lower than its estimated
net realizable value.
 
    In 1997, the Company purchased a 20,275 square foot office building and an
adjacent vacant lot for investment purposes. The net book value of the property
was $2,134,000 and $2,098,000 at September 30, 1997 and March 31, 1998,
respectively. The Company leases the office space to tenants under one to three-

NOTE 8 - ECONOMIC DEPENDENCE
 
    A material part of the Company's business is dependent on one customer, the
loss of which could have a material effect on the Company. For the years ended
September 30, 1995, 1996 and 1997 and the six months ended March 31, 1998,
approximately 29.5%, 24%, 46.9% and 41.7%, respectively, of revenues were
attributable to this customer. At September 30, 1996 and 1997 and March 31,
1998, accounts receivable from this customer represented approximately 41.1%,
23.4% and 30%, respectively, of total accounts receivable.
 
NOTE 9 - STOCK OPTION PLANS
 
    Prior to 1993, the Company implemented a nonqualified compensatory stock
option plan with the President. Under this Plan, options to purchase 90,000
shares of the Company's stock were granted at an option price of $2.70 per
share. These options are currently exercisable by the President.
 
    During the year ended September 30, 1994, the Company and three key
employees entered into employment contracts which voided all prior compensatory
stock option plans other than that of the President's. Under these new
contracts, the Company granted 20,000 shares to each of the three employees at
an exercise price of $15 per share. Fair market value was $28 per share at the
date of the grant. Each

employee still employed at September 30, 1998, is entitled to exercise his
option to purchase 20,000 fully vested shares. Accordingly, the Company has
expensed $156,000 during each of the years ended September 30, 1995, 1996 and
1997 and $78,000 for the six months ended March 31, 1998. These shares, when
exercised, cannot be sold until September 30, 2003. The Company has the first
right to purchase the shares upon exercise but is not obligated to do so.
 
    The accumulated expense resulting from the difference between the exercise
prices and fair market values at the respective date of grant has been
classified as a long-term liability in deferred compensation.

                UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA
 
    The Unaudited Pro Forma Consolidated Financial Data presents the following
pro forma data for the Company: (i) the results of operations for the year ended
December 31, 1997 and the three months ended March 31, 1998; and (ii) the
financial position as of March 31, 1998. The Unaudited Pro Forma Consolidated
Financial Data should be read in conjunction with the Company's: (i) audited
consolidated financial statements and notes thereto included in the Form 10-K
for the year ended December 31, 1997; and (ii) unaudited consolidated financial
statements and notes thereto included in the Form 10-Q for the quarter ended
March 31, 1998. Capitalized terms, unless defined herein, have the meaning
ascribed to them in the aforementioned Forms 10-K and 10-Q.
 
    The following Unaudited Pro Forma Consolidated Financial Data for the year
ended December 31, 1997 and the three months ended March 31, 1998 presents the
results of operations of the Company as if the following transactions had
occurred as of January 1, 1997: (i) the acquisition of Avtech Corporation
("Avtech") for $84.7 million in cash, including an estimated $1.3 million of
acquisition related costs; (ii) the Audio International acquisition, which
occurred on November 14, 1997 as described in the Company's Form 10-K; (iii) the
Recapitalization, the IPO, and the application of the net proceeds therefrom,
which were completed on April 16, 1997 as described in the Company's Form 10-K;
and (iv) the sale of 2,206,177 shares of common stock, and the application of
the net proceeds therefrom, which was completed in April 1998 (the "Follow-On
Equity Offering"), as described in the Company's Form 10-Q. The balance sheet
data as of March 31, 1998 is adjusted to reflect the following transactions as
if they occurred on March 31, 1998: (i) the Avtech acquisition; and (ii) the
Company's Follow-On Equity Offering and the application of the net proceeds
therefrom. The data does not include the acquisition of Dettmers Industries Inc.
("Dettmers") because inclusion would not have a material effect on such data.
 
    The Unaudited Pro Forma Consolidated Financial Data presenting the results
of operations for the year ended December 31, 1997 reflects the unaudited
consolidated financial statements of Audio International for the period from
January 1, 1997 through November 14, 1997, the date on which it was acquired.
The Avtech results of operations data for all periods is unaudited and was
derived from audited and unaudited financial statements as of and for the
appropriate periods since it was not acquired until June 26, 1998. Avtech's
fiscal year end, prior to its acquisition by the Company, was September 30th.
The balance sheet of Avtech as of March 31, 1998 was derived from its audited
financial statements for the six months ended March 31, 1998.
 
    The Company believes the Unaudited Pro Forma Consolidated Financial Data
contains all adjustments necessary for a fair presentation of the above
described transactions. The pro forma adjustments are based upon available
information and certain assumptions that the Company believes are reasonable.
With respect to the Avtech pro forma acquisition adjustments described in the
accompanying notes, the allocation of the purchase price is preliminary and
subject to final determination by the Company. The Unaudited Pro Forma
Consolidated Financial Data is presented for illustrative purposes only and is
not necessarily indicative of the results of operations that would have occurred
had the transactions been consummated on the dates indicated, or that may be
obtained in future periods.
