EXHIBIT 2.1

                       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.
 
                                       1

       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

       interests, equities and restrictions whatsoever.
 
           2.2.3  AUTHORIZATION OF THE SHAREHOLDERS.  Each of the Shareholders
       has all requisite power, authority and legal capacity and is competent to
       execute and deliver this Agreement, perform its obligations hereunder and
       consummate the transactions contemplated hereby. This Agreement
       constitutes the legal, valid and binding obligation of each of the
       Shareholders, enforceable against each of them in accordance with its

       flows for the years ended September 30, 1997, 1996 and 1995 and for the
       six months ended March 31, 1998 (all of such documents referred to
       collectively as the "Delivered Financial Statements"). The March 31, 1998

       presently anticipated. The Delivered Financial Statements (i) are true,
       correct and complete in all material respects, (ii) have been prepared

       accounting principles applied on a consistent basis for such periods, and
       (v) fairly present the financial position of Avtech as of the dates
       stated and the results of operations and cash flows of Avtech for the
       periods then ended in accordance with such practices. On the date of this
       Agreement, Avtech does not have any material contingent liabilities,
       liabilities for taxes, unusual forward or long-term commitments or
       unrealized or anticipated losses from any unfavorable commitments, except
       as referred to or reflected or provided for in the balance sheets in the
       Delivered Financial Statements. Since March 31, 1998, there has been no
       material adverse change in the financial condition, operations, business
       or prospects taken as a whole of Avtech from that set forth in the March
       31, 1998 Delivered Financial Statements. The Shareholders covenant and
       agree to deliver to DAH at or prior to the Closing Date, the unqualified
       opinion that the financial statements are prepared in accordance with
       GAAP and the requirements of Regulation S-X promulgated by the Securities
       and Exchange Commission ("Regulation S-X") of an independent accounting
       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".
       When delivered, the
 
                                       3

    authority except as set forth on Schedule 2.2.9. The amount of each of the
    royalties and license fees presently paid by or on behalf of Avtech for the
    use of any Intellectual Property is listed in Schedule 2.2.9.
 
        2.2.10  RESTRICTIVE DOCUMENTS OR LAWS.  With the exception of the
    matters listed on Schedule 2.2.10, Avtech is not a party to or bound under
    any certificate, mortgage, lien, lease, agreement, contract, instrument,
    vote, order, judgment or decree, or any similar restriction not of general
    application which materially adversely affects (i) the condition, financial
    or otherwise, of Avtech or any part of the Property; (ii) the continued
    operation by DAH of the business of Avtech after the Closing Date on
    substantially the same basis as said business was theretofore operated; or
    (iii) the consummation of the transactions contemplated in this Agreement.
 
        2.2.11  INSURANCE.  Schedule 2.2.11 is a true, correct and complete list
    of all insurance policies and bonds in force in which Avtech is named as an
    insured party, as respects the business of Avtech, or for which Avtech has

    2.2.11, all such policies or bonds are identical in terms, coverage and
    exclusions to the policies
 
                                       6

    expiring on or about February 18, 1998 as previously delivered to DAH; and
    are currently in full force and Avtech has not received any notice from any
    such insurer with respect to the cancellation of any such insurance. Avtech
    will continue all of such insurance in full force and effect up to and
    including the Closing Date. All premiums due and payable on such policies
    have been paid. Avtech is not a co-insurer under any term of any insurance
    policy.
 
        2.2.12  BANK ACCOUNTS, DEPOSITORIES AND POWERS OF ATTORNEY.  Schedule
    2.2.12 is a true, correct and complete list of the names and locations of
    all banks or other depositories in which Avtech maintains accounts or safe
    deposit boxes, and the names of the persons authorized to draw thereon,
    borrow therefrom or have access thereto. No person or entity holds a power
    of attorney on behalf of Avtech.
 
        2.2.13  REAL PROPERTY.  Schedule 2.2.13 contains a complete and accurate
    legal description of each parcel of the Real Property. Except as set forth
    in Schedule 2.2.13, Avtech has no interests in real property. The Real
    Property constitutes all of the real property now used in and necessary for
    the conduct of the business of Avtech as presently conducted. Except as set
    forth on Schedule 2.2.13, all of the Real Property is held free and clear of
    all mortgages, pledges, liens, security interests, encumbrances and
    restrictions of any nature whatsoever. No consent is required by the terms
    of any agreement relating to Avtech's Real Property, from any person
    whatsoever, to effect the transactions contemplated hereby, such that as of
    immediately after the Closing Date all of the Real Property will be, free
    and clear of all mortgages, pledges, liens, security interest, encumbrances,
    restrictions and claims of any nature whatsoever (except to the extent
    listed on Schedule 2.2.13). Except as set forth in Schedule 2.2.13, all of
    the Real Property, and all real property, buildings and structures located
    thereon, is suitable for the purpose or purposes for which it is being used,
    and is in such condition and repair as to permit the continued operation of
    said businesses. None of the Real Property, buildings or structures is in
    need of material maintenance or repairs except for ordinary, routine
    maintenance and repairs. 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
    Avtech 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. The utilities servicing the Real Property are adequate to permit
    the continued operation of the business of Avtech and there are no pending
    or threatened zoning, condemnation or eminent domain proceedings, building,
    utility or other moratoria, or injunctions or court orders which would
    materially affect such continued operation. Schedule 2.2.13 lists, and
    Avtech has furnished or made available to DAH, copies of all engineering,
    geologic and environmental reports prepared by or for Avtech with respect to
    the Real Property.
 
        2.2.14  PERSONAL PROPERTY.  Except as set forth in Schedule 2.2.14, and
    except with respect to personal property leased pursuant to the Personal
    Property Leases listed on Schedule 2.2.14, Avtech has good, valid and
    marketable title to all of its assets and properties which are 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 balance sheet included in the March 31,
    1998 Delivered Financial Statements. The Personal Property constitutes all
    of the personal property now used in and necessary for the conduct of the
    business of Avtech as presently conducted, and is held free and clear of all
    mortgages, pledges, liens, security interests, encumbrances and restrictions
    of any nature whatsoever. Except as set forth in Schedule 2.2.14, no
    financing statement naming Avtech as debtor has been filed in any
    jurisdiction, and Avtech is not a party to or bound under any agreement or
    legal obligation authorizing any party to file any such financing statement.
    Schedule 2.2.14 contains a complete and accurate description of all
    machinery, equipment, tooling, parts, furniture, supplies and other tangible
    personal property having an individual value of $5,000 or more owned or used
    by Avtech. Schedule 2.2.14 contains a complete and accurate description of
    all automobiles, trucks and other vehicles owned or used by Avtech. Except
    as noted on Schedule 2.2.14
 
                                       7

    as unsuitable, all machinery and equipment and tangible personal property
    owned or used by Avtech and material to the operation of the business is
    suitable for the purpose or purposes for which it is being used, and is in
    such condition and repair as to permit the continued operation of said
    business. None of such machinery or equipment is in need of material
    maintenance or repairs except for ordinary, routine maintenance and repairs.
 
        2.2.15  ENVIRONMENTAL MATTERS.  Except as set forth on Schedule 2.2.15,
    the operations of Avtech are in compliance with 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 Avtech.
    Without limiting the generality of the foregoing, and by way of example
    only, except as set forth on Schedule 2.2.15:
 
           (a) There has not been, and is not occurring, any Release of any
       Hazardous Substance on any real property owned or used by Avtech. 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) Avtech has never sent a Hazardous Substance to a site which,
       pursuant to CERCLA or any similar state law, (A) has been placed, or 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) Avtech has never been or is currently in violation of any
       provision of state or local laws or regulations applicable to the
       generation, processing, storage, remediation, or disposal of any
       Hazardous Substance or material similarly controlled or regulated by such
       laws.
 
           (d) Avtech is not involved in any suit or has received notice of any
       claim relating to personal injuries from exposure to Hazardous Substances
       or such other controlled or regulated materials.
 
        2.2.16  BROKERS, FINDERS.  Except as set forth on Schedule 2.2.16, the
    transactions contemplated herein were not submitted to Avtech by any broker
    or other person entitled to a commission or finder's fee thereon, and were
    not with the consent of Avtech submitted to DAH by any such broker or other
    person. Except as set forth on Schedule 2.2.16, neither Avtech nor any of
    its officers, directors or employees has engaged any broker or finder or
    incurred or taken any action which may give rise to any liability against
    itself 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 Avtech in connection with this Agreement or the transactions
    contemplated hereby. No investment banking, financial advisory or similar
    fees have been incurred or are or will be payable by Avtech in connection
    with this Agreement or the transactions contemplated hereby; all amounts to
    be paid to Dain Rauscher Wessels will be paid by the Shareholders.
 
        2.2.17  LEGAL PROCEEDINGS. ETC.  Except as set forth on Schedule 2.2.17,
    there is no claim, litigation, action, suit or proceeding, administrative or
    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

    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

       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

       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

       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

       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

       (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
       Strategic Alliance. No Strategic Alliances have been terminated by Avtech
       since April 1, 1998.
 
           2.2.31  PAYMENTS AND EXPENDITURES.  Except as set forth in Schedule
       2.2.31 since March 31, 1998, Avtech has not (i) made any payment or
       incurred any liability on behalf of any Shareholder, (ii) made any
       payment to or on behalf of any Shareholder except for the Shareholder's
       salary and expense reimbursements made in the ordinary course of
       business, or (iii) paid any amount not in the ordinary course of Avtech's
       business.
 
           2.2.32  NEW COMPETITIVE PRODUCTS, PRICING, TECHNOLOGICAL
       DEVELOPMENTS, COMPETITION. Except as disclosed in Schedule 2.2.32, to the
       best knowledge of the Principal Shareholders, there are no (i) products
       introduced by others since October 1, 1997 which are competitive with the
       products of Avtech, (ii) material reductions in the prices of products of
       products competitive with the products of Avtech, (iii) technological
       developments announced which would make any of Avtech's products obsolete
       or (iv) entries by any new competitor into Avtech's markets, in each case
       other than as described in the Confidential Information Memorandum dated
       March, 1998 previously delivered to DAH (the "Information Memorandum").
 
           2.2.33  KEY EMPLOYEES.  Except as disclosed in Schedule 2.2.26, since
       March 31, 1998 no Key Employees have terminated employment with Avtech
       and no Key Employees have given notice to Avtech or to any Principal
       Shareholder of termination. The Principal Shareholders anticipate that
       all Key Employees will continue employment with Avtech after the Closing
       Date.
 
           2.2.34  COMPLETE DISCLOSURE.  No representation or warranty made by
       Avtech or any of the Shareholders in this Agreement, and no exhibit,
       schedule or certificate furnished to DAH by or on behalf of Avtech or any
       of the Shareholders pursuant to this Agreement or in connection with the
       transactions contemplated hereby or thereby, including the Confidential
       Informational Memorandum, contains or will contain, any untrue statement
       of a material fact or omits or will omit to state a material fact
       necessary to make the statements contained herein and therein not
       misleading.
 
    3.  COVENANTS.
 
        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
       (including attorneys, accountants and investment bankers) who agree to
       maintain the confidentiality of such information, each of the
       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
 
                                       14

       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.
 
           3.1.2  [Intentionally Deleted].
 
           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
       the Principal Shareholders agrees that on and after the date hereof and
       prior to the Closing Date:
 
           (a) The business and operations, activities and practices of Avtech
       shall be conducted only in the ordinary course of business and consistent
       with past practice;
 
           (b) No change shall be made in the articles of incorporation or
       bylaws of Avtech;
 
           (c) No change shall be made in the number of shares of authorized or
       issued capital stock of Avtech, nor shall any option, warrant, call,
       right, commitment or agreement of any character be granted or made by
       Avtech relating to its equity; except that all of the outstanding options
       shall be exercised on or prior to the Closing Date as and in the amounts
       set forth in Schedule 2.2.2;
 
           (d) No dividend shall be declared or paid or other distribution
       (whether in cash, stock, property or any combination thereof) or payment
       declared or made in respect of the Avtech Common Shares by Avtech, nor
       shall Avtech purchase, acquire, redeem or split, combine or reclassify
       any shares of the capital stock of Avtech;
 
           (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
       telephone, and thereafter promptly confirm in writing, if any such
       information is requested from, or any Acquisition Proposal is, to the
       knowledge of such Shareholder, received by Avtech, Dain Rauscher Wessels
       or such Shareholder. As used in this Agreement, "Acquisition Proposal"
       shall mean any proposal received by Avtech or any Principal Shareholder
       prior to the Closing Date for a merger or other business combination
       involving Avtech or for the acquisition of, or the acquisition of a
       substantial equity interest in, or a substantial portion of the assets of
       Avtech, other than the one contemplated by this Agreement.
 
           (f) Except as set forth in Schedule 3.1.4(f), the Principal
       Shareholders will not permit Avtech to:
 
               (A) incur, become subject to, or suffer, or agree to incur,
           become subject to or suffer, any obligation or liability (absolute or
           contingent) except current liabilities incurred, and obligations
           entered into in the ordinary course of business;
 
               (B) discharge or satisfy any lien or encumbrance or pay any
           obligation or liability (absolute or contingent) other than
           liabilities payable in the ordinary course of business;

           encumbrance any of the Property or agree so to do;

           assets, or cancel or agree to cancel any debt or claim, except in

           value;

               (G) increase the rate of compensation payable or to become

           incur any liability or obligation of a material nature to any labor
           organization;
 
               (J) make or agree to make any accrual or arrangement for or
           payment of bonuses or special compensation of any kind to any
           Restricted Employee;
 
               (K) make or agree to make any accrual or arrangement for or
           payment of bonuses or special compensation of any kind to any

           business and in accordance with Avtech's practice;
 
               (L) directly or indirectly pay or make a commitment to pay any
           severance or termination pay to any Key Employee;

           by GAAP;
 
               (O) offer or extend more favorable credit terms, discounts or
           allowances than were offered or extended regularly on and prior to

           accordance with Avtech's past practice;
 
               (P) make capital expenditures in excess of $100,000 in the
           aggregate, or make any commitments for such capital expenditures;

           (g) Each of the Principal Shareholders will use their respective
       reasonable efforts to preserve Avtech's business organization materially
       intact, to keep available to Avtech the present service of Avtech's
       employees; and to preserve for Avtech the good will of its suppliers,
       customers and others with whom business relationships exist;
 
           (h) In light of the provisions of clause (i) of Section 1.2.3, the
       Principal Shareholders will take all necessary actions to assure that (i)
       Avtech does not accelerate the conversion of other assets to Cash and
       (ii) Avtech timely pays all of its obligations; and
 
           (i) None of the Principal Shareholders will take, agree to take or
       permit to be taken any action or do or permit to be done, anything in the
       conduct of the business of Avtech, or otherwise, which would be contrary
       to or in breach of any of the terms or provisions of this Agreement or
       which would cause any of the representations or warranties of the
       Shareholders contained herein to be or become untrue in any material
       respect.

       and satisfaction of conditions hereunder.
 
           3.1.6  FURTHER ASSURANCES.  On and after the Closing Date, the
       Shareholders shall prepare, execute and deliver, at DAH's expense, such

       consummate, in any other manner, the terms and conditions of this
       Agreement.
 
           3.1.7  PRESS RELEASES AND ANNOUNCEMENTS.  DAH and the Principal

           3.1.11  RELEASE.  Each Shareholder does hereby release and discharge
       Avtech and its officers, directors and agents (the "Releasees") from any

                                       17

       action which such Shareholder has against any of the Releasees arising
       from their status as a Shareholder. This release applies to any and all
       such claims, demands or causes of action, whether known or unknown,
       contingent or matured. The release granted in this Section 3.1.11 shall
       become effective concurrent with the Closing. If the transaction
       contemplated by this Agreement does not close, this release shall be null
       and void.

       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

       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.

        6.2  ENTIRE AGREEMENT.  This Agreement, the Exhibits and Schedules
    hereto, and the documents referred to herein and therein embody the entire
    agreement and understanding of the parties hereto with respect to the
    subject matter hereof, and supersede all prior and contemporaneous
    agreements and understandings, oral or written, relative to said subject
    matter.
 
        6.3  BINDING EFFECT; ASSIGNMENT.  This Agreement and the rights and
    obligations arising hereunder shall inure to the benefit of and be binding
    upon Avtech, its DAH, its successors and permitted assigns, and the
    Shareholders, their heirs, legal representative and permitted assigns.
    Neither this Agreement nor any of the rights, interest or obligations
    hereunder shall be transferred or assigned (by operation of law or
    otherwise) by any of the parties hereto without the prior written consent of
    the other party or parties except that DAH shall have the right to (i)
    assign, in whole or in part, its rights hereunder to one or more affiliates
    of DAH, which in each case shall be a wholly-owned subsidiary of DAH and

    under its senior credit facility to secure its obligations thereunder. Any
    transfer or assignment of any of the rights, interests or obligations
    hereunder in violation of the terms hereof shall be void and of no force or

    Agreement in construing or interpreting any provision hereof.
 
        6.5  WAIVER; CONSENT.  This Agreement may not be changed, amended,
    terminated, augmented, rescinded or discharged (other than by performance),

                                       21

    by the parties hereto, and no waiver of any of the provisions or conditions
    of this Agreement or any of the rights of a party hereto shall be effective
    or binding unless such waiver shall be in writing and signed by the party

    its obligations or representations hereunder or thereunder shall be deemed
    to be a waiver of any other condition or subsequent or prior breach of the
    same or any other obligation or representation by the other party, nor shall
    any forbearance by the first party to seek a remedy for any noncompliance or
    breach by the other party be deemed to be a waiver by the first party of its
    rights and remedies with respect to such noncompliance or breach.
 
        6.6  NO THIRD PARTY BENEFICIARIES.  Nothing herein, expressed or
    implied, is intended or shall be construed to confer upon or give to any

    any rights, remedies or other benefits under or by reason of this Agreement.
 
        6.7  COUNTERPARTS AND FACSIMILE SIGNATURES.  This Agreement may be
    executed simultaneously in multiple counterparts, each of which shall be
    deemed an original, but all of which taken together shall constitute one and
    the same instrument. The signature page of this Agreement when transmitted
    by facsimile shall be effective execution and delivery of this Agreement.
 
        6.8  GENDER.  Whenever the context requires, words used in the singular
    shall be construed to mean or include the plural and vie versa, and pronouns
    of any gender shall be deemed to include and designate the masculine,
    feminine or neuter gender.
 
        6.9  GOVERNING LAW.  This Agreement shall in all respects be constructed
    in accordance with and governed by the laws of the State of Delaware. Any
    and all disputes arising under or in connection with this Agreement or the
    transactions contemplated hereby shall be resolved by binding arbitration
    before JAMS/Endispute, which arbitration shall be conducted in Seattle,
    Washington in accordance with the rules of JAMS/Endispute.
 
        6.10  TRANSACTION EXPENSES.  All of the expenses of the Shareholders
    incurred in connection with the transactions contemplated by this Agreement,
    including but not limited to the fees of counsel, investment bankers, title
    insurance premiums, other investment advisors, accountants (including audit
    fees relating to the Audited Financial Statements and the Closing Date
    Balance Sheet) and consultants (collectively, the "Shareholder Closing
    Expenses"), shall be paid for by the Shareholders. None of the Shareholder
    Closing Expenses shall be accrued or paid by Avtech or DAH. The Principal
    Shareholders represent and warrant that all of the persons engaged in
    connection with the transactions contemplated hereby, to whom Shareholder
    Closing Expenses may be payable, have no recourse to Avtech, and that
    adequate provision has been made for the payment of all unpaid amounts by
    the Paying Agent or the Escrow Agent pursuant to Section 1.2.3 hereof.
 
        6.11  CLOSING DATE.  The date on which the transaction shall close (the
    "Closing Date") shall be June 26, 1998 unless the conditions in Sections
    5.1.6 and 5.1.7 have not been completed, in which case, the Closing shall be
    3 business days following the completion of each of the conditions specified
    in Sections 5.1.6 and 5.1.7; PROVIDED, HOWEVER, that (i) each of the parties
    hereto shall use its best efforts to satisfy each of the conditions
    precedent to the Closing Date which is satisfied by the delivery of
    documents (other than those to be dated on the Closing Date) no later than
    June 24, 1998; and (ii) nothing in this language waives any of the other
    closing conditions specified in Section 5.
 
    7.  TERMINATION.  This Agreement may be terminated by the parties and the
contemplated transactions abandoned at any time prior to closing, as follows:
 
        (a) By the written consent of DAH and Shareholders holding a majority of
    the Avtech Common Shares;
 
                                       22

        (b) By either DAH or Shareholders holding a majority of the Avtech
    Common Shares, upon written notice of all other parties of this Agreement,
    at any time after July 31, 1998, if the Closing Date shall not have occurred
    by such date; PROVIDED, HOWEVER, that the right to terminate this Agreement
    under this paragraph (b) shall not be available to any party which has
    intentionally breached this Agreement or whose failure to comply with its
    covenants and agreements set forth in this Agreement shall have been the
    primary cause of the closing not occurring.
