     2.4.1 April Net Asset Statement. Schedule 2.4.1 delivered hereunder sets
forth (i) a statement of the Assets and Assumed Liabilities as of April 30, 2001
(the "April Net Asset Statement") which accurately reflects the Net Asset Value
as of such date, and (ii) a reconciliation of the April Net Asset Statement to
the April Balance Sheet delivered pursuant to Section 3.4.1(iii) hereof. The
April Net Asset Statement has been prepared in accordance with GAAP applied
consistent with past practice, except that (a) the line items for "LIFO Reserve"
and "Overhead in Inventory" are not reflected, and (b) footnotes and year end
adjustments have been omitted.

     2.4.2 Closing Net Asset Statement. Within fifteen (15) days after the
Closing Date, Seller shall deliver to Buyer a statement of the Assets and
Assumed Liabilities as of the close of business at 5:30 PM on the Closing Date
(the "Closing Net Asset Statement") which reflects the Net Asset Value as of
such date. The Closing Net Asset Statement shall present accurately the
financial condition of the Assets and Assumed Liabilities as of the date thereof
and shall be prepared in accordance with GAAP applied consistent with past
practice and on a basis consistent with the April Net Asset Statement. Buyer and
its representatives and accountants shall have the right to participate in and
observe the process of the preparation of the Closing Net Asset Statement and
shall have such access as Buyer may reasonably request to any books, records,
work papers or other information that may be used or useful in preparing the
Closing Net Asset Statement and the calculation of the Final Closing Net Asset
Value (as defined below).

     2.4.3 Objections and Resolution. Within sixty (60) days after receipt of
the Closing Net Asset Statement, Buyer shall either inform Seller in writing
that the Closing Net Asset Statement is acceptable or object to the Closing Net
Asset Statement in writing setting forth in reasonable detail a description of
Buyer's objections. If Buyer fails to deliver written objection to Seller within
such sixty-day period, or if Buyer informs Seller in writing that the closing
Net Asset Statement is acceptable, the Closing Net Asset Statement delivered by
Seller shall be deemed final (the "Final Closing Net Asset Statement") and the
Net Asset Value as of the Closing Date reflected thereon shall be the "Final
Closing Net Asset Value." If Buyer objects as provided above and if Seller does
not agree with Buyer's objections (it being agreed that the failure of Seller to
deliver written notice to Buyer of Seller's disagreement with Buyer's objection
within fifteen (15) days of receipt of such objection shall be deemed acceptance
by Seller) and such objections are not resolved on a mutually agreeable basis
within fifteen (15) days after delivery of notice to Buyer of Seller's
disagreement to Buyer's objection thereof, then a disagreement between Seller
and Buyer regarding the same shall be deemed to exist (the "Disagreement"). If a
Disagreement is deemed to exist, the Escrowed Amount shall be paid out or
retained, in whole or in part, pursuant to the terms of the next succeeding
sentence and the Escrow Agreement (which the parties hereto hereby covenant
shall be consistent with the terms of this Subsection 2.4.3). On the next
business day following the occurrence of the
<PAGE>

Disagreement, Buyer shall notify the Escrow Agent of the Net Asset Value that
Buyer asserts should be the Final Closing Net Asset Value (the "Buyer's Asserted
NAV") and, on the next succeeding business day, the Escrow Agent shall (a) if
Buyer's Asserted NAV is $6,046,000 or greater, pay to Seller the Escrowed
Amount, or (b) if Buyer's Asserted NAV is greater than $5,646,000 but less than
$6,046,000, pay to Seller an amount equal to the Buyer's Asserted NAV less
$5,646,000 and retain the balance, or (c) if Buyer's Asserted NAV is less than
or equal to $5,646,000, retain the entire Escrowed Amount. After giving effect
to the previous sentence, the amount that is retained in escrow shall be deemed
to be the Escrowed Amount for purposes of Subsection 2.4.4 below. Once a
Disagreement is deemed to exist, Buyer and Seller shall select an independent
auditing firm, which firm shall not be the regular auditing firm of either Buyer
or Seller, or, if Buyer and Seller cannot agree on the independent auditing firm
to be retained, Buyer and Seller shall each submit the name of one independent
auditing firm that is not the regular auditing firm of such party and the
independent auditing firm shall be selected by lot from those two firms (by
whichever method selected, the "Independent Accountants"). The Independent
Accountants shall resolve the Disagreement within thirty (30) days after the
mutual engagement of the Independent Accountants and their decision in resolving
the Disagreement shall be final and binding upon, and their fees, costs and
expenses shall be shared equally by, Seller and Buyer. Each party hereto shall
bear the fees, costs and expenses of its own accountants. Upon resolution of any
such Disagreement, the resulting Closing Net Asset Statement shall be deemed the
Final Closing Net Asset Statement and the Net Asset Value as of the Closing Date
reflected thereon shall be the Final Closing Net Asset Value.

     2.4.4 Final Adjustment. If the Final Closing Net Asset Value is greater
than $6,046,000 (the "Target Net Asset Value"), Buyer shall pay to Seller the
absolute difference between such two amounts, and the Escrow Agent shall pay to
Seller the Escrowed Amount. If the Final Closing Net Asset Value is equal to the
Target Net Asset Value, the Escrow Agent shall pay to Seller the Escrowed
Amount. If the Final Closing Net Assert Value is less than the Target Net Asset
Value and the difference is less than the Escrowed Amount, the absolute
difference between the Target Net Asset Value and the Final Closing Net Asset
Value shall be paid to Buyer by the Escrow Agent from the Escrowed Amount and

interest in any pending or potential claim against the United States Government
or any prime contractor, subcontractor or vendor arising under or relating to
any Government Contract or Government Bid. Schedule 3.11.3 lists each Government
Contract which, to Seller's Knowledge, is currently under audit (other than
routine audits conducted in the ordinary course of business) by the United
States Government or any other person that is a party to such Government
Contract.

     3.11.4 Eligibility; Systems Compliance. Except as set forth in Schedule
3.11.4, since January 1, 1998, neither Seller nor Elecsys or any of their
respective directors, officers, or employees have ever been debarred or
suspended from participation in the award of contracts with the United States
Department of Defense or any other United States Government entity or have been
denied award of a Government Contract on the basis of a determination of
nonresponsibility or ineligibility. To Seller's Knowledge, there exist no facts
or circumstances that would warrant the institution of suspension or debarment
proceedings or the finding of nonresponsibility or ineligibility on the part of
Seller or Elecsys with respect to any prior, subsisting or future Government
Contract or Government Bid. To Seller's Knowledge no payment has been made by
Seller or Elecsys, or by any Person on behalf of Seller or Elecsys, in
connection with any Government Contract in violation of applicable procurement
laws or regulations. Except as set forth in Schedule 3.11.4, the cost
accounting, materials management
<PAGE>

reflected in the Financial Statements, with respect to the Government Contracts
and the Government Bids are in compliance in all material respects with all
applicable laws and regulations.

     3.11.5 Test and Inspection Results. Except as set forth in Schedule 3.11.5,
to the Knowledge of Seller, all test and inspection results provided by Seller
or Elecsys to the United States Government pursuant to any Government Contract
or to any other Person pursuant to a Government Contract or as a part of the
delivery to the United States Government or to any other Person pursuant to a
Government Contract of any article, spare part, apparatus or any intangible
(including software and databases) which were designed, developed, engineered or
manufactured by Seller, Elecsys or any subcontractors of Seller or Elecsys, were
complete and correct in all material respects as of the date so provided. Except
as set forth in Schedule 3.11.5, Seller and Elecsys have provided all test and
inspection results to the United States Government or to any other Person
pursuant to a Government Contract as required by applicable law and the terms of
the applicable Government Contract.

     3.11.6 Government Furnished Equipment. Schedule 3.11.6 identifies by
description or inventory number and contract all equipment and fixtures loaned,
bailed or otherwise furnished to or held by Seller or Elecsys (or by
subcontractors on behalf of Seller or Elecsys) by or on behalf of the United
States as of the date stated therein (said equipment and fixtures are herein
referred to as the "GFE"). Seller or Elecsys, as the case may be, has certified
to the United States Government in a timely manner that all GFE is in good
working order, reasonable wear and tear excepted, and otherwise meets the
requirements of the applicable contract. There are no outstanding loss, damage
or destruction reports that have been or should have been submitted to the
United States Government in respect of any GFE. To the Knowledge of Seller, in
respect of the GFE, Schedule 3.11.6 is accurate and complete as of the date
hereof, and if dated as of the Closing Date would contain only those additions
and omit only those deletions of equipment and fixtures that have occurred in
the ordinary course of business. The GFE is in the possession of ASI or Seller,
or a subcontractor of Seller or Elecsys, and is located at the place identified
in the list of GFE referred to in Schedule 3.11.6.

Code or any other provision of applicable law. Seller is not a corporation other

connection with any Plan that reasonably could be expected to result in the
imposition of a penalty pursuant to Section 502(1) of ERISA, damages pursuant to

material liability under such title other than for the payment of premiums to
the Pension Benefit Guaranty Corporation ("PBGC"), all of which have been paid
when due;

     (e) No Retirement Plan has been terminated; nor have there been any

the Business; and

     (k) All Plans are in full compliance with the relevant provisions of ERISA
and the Code, the regulations and published authorities thereunder, and all
other laws applicable with respect to all such Plans. Seller and Elecsys have

nothing express or implied herein shall obligate Buyer to provide continuing
employment to any Employee for a period in excess of one month following the

Hired Employees for a period from the Closing Date through the remainder of the
annual term of such Welfare Plans on the same or similar terms as are available

Plan, including a direct rollover to the Buyer's Plan in accordance with Section
401(a)(31) or to make a voluntary transfer of their account balances under the
Seller's Plan to the Buyer's Plan, which voluntary transfer may include any
outstanding loan balance. Any assets
<PAGE>

transferred to the Buyer's Plan either as a voluntary transfer or a direct
rollover shall be in the form of cash or stock, except that participant loan
balances may be transferred in the form of notes.

     (a) Seller shall retain all obligations and liabilities under all Plans
listed in Schedule 3.14.3, including obligations relating to or arising under
Part 6 of Title I of ERISA and Section 4980B of the Code. Seller shall
indemnify, and defend Buyer for and hold Buyer harmless from and against, and
pay and reimburse Buyer for, any and all claims, losses, payments, audits, and
assessments relating to or arising out of any and all Plans listed in Schedule
3.14.3 and obligations under this Subsection 5.12.4(a).

     (b) Seller shall retain financial liability (i) for expenses incurred by
the Employees but not reported as of the Closing Date respecting claims arising

tuition reimbursement program, if any.

     5.12.5 Access to Information. Upon request of Buyer, Seller shall provide
Buyer reasonable access to data before and after the Closing (including computer
data and personnel records) regarding the dates of hire, benefits, compensation
and job description of Employees and such other information as Buyer shall
reasonably request. At the request of Buyer and upon reasonable scheduling
provided by Seller, Seller shall provide Buyer with reasonable opportunities to
enter into discussions with and to advise any of the Employees concerning the
terms of future employment of such individuals by Buyer and shall permit Buyer,
subject to the participation of Seller, reasonable access upon request to
Employees for such purpose. Seller shall not discourage any Employees from
accepting an offer of employment made by Buyer to such Employees. Buyer and
Seller shall cooperate in preparing and disbursing materials concerning the
transaction contemplated by this Agreement or the effect of the transaction upon
the Employees' employment or the terms or conditions of the Employees'
employment. Buyer and Seller shall provide each other with reasonable
opportunity to review any written materials and to attend any scheduled meetings
concerning the foregoing.

     Section 5.13 Assignment of Contracts and Rights. Prior to Closing, Seller
and Elecsys will give notices to third parties of the transfer of the Assets
contemplated by this Agreement and will use commercially reasonable efforts to
obtain the Consents. After the Closing Date, Seller, Elecsys, with respect to
the Business, and Buyer will cooperate and will each use commercially reasonable
efforts to obtain any Consents that are not obtained prior to the Closing Date
and that are subject to Buyer's waiver, granted in its sole discretion, of the
relevant closing condition herein. Anything to the contrary notwithstanding,
this Agreement shall not operate to assign any Asset or Contract, or any claim,
right or benefit arising thereunder or resulting therefrom, if an attempted
assignment thereof, without the consent of a third party thereto, would
constitute a
<PAGE>

breach, default or other contravention thereof or in any way adversely affect
the rights of Seller or Buyer thereunder. In the event that a Consent required
to assign any Contract is not obtained on or prior to the Closing Date, then,
subject always to the terms of the applicable Contract and to the extent
permitted by law, the parties will use their best efforts to (i) provide to
Buyer the benefits of the applicable Contract to the extent related to the
Business, (ii) relieve Seller, or Elecsys, with respect to the Business, to the
extent possible, of the performance obligations of the applicable Contracts,
(iii) cooperate in any reasonable and lawful arrangement designed to provide the
benefits to Buyer, including entering into subcontracts for performance, and
(iv) enforce at the request of Buyer and for the account of Buyer any rights of
Seller or Elecsys, with respect to the Business, arising from any such Contract
(including the right to elect to terminate such Contract in accordance with the
terms thereof upon the request of Buyer).

third party in the name of or to Seller or Elecsys, in connection with the
Business, in connection with or arising out of the Assets and Assumed
Liabilities on or after the Closing Date shall be held by Seller or Elecsys, as
the case may be, in trust for the benefit of Buyer and, promptly upon receipt by
Seller or Elecsys, in connection with the Business, of any such payment or
reimbursements, Seller or Elecsys, as the case may be, shall pay over to Buyer
the amount of such payment or reimbursement without right of set off, provided
that any such payment or reimbursement that is not paid by Seller or Elecsys, as
the case may be, within 30 days of receipt shall bear interest at a rate of 10%
per annum until it is paid, which interest, along with the principal amount of
such payment or reimbursement, shall be payable to Buyer on demand.

     5.14.2 In Trust For Seller. All payments and reimbursements made by any
third party in the name of or to Buyer in connection with or arising out of the
Excluded Assets and Excluded Liabilities on or after the Closing Date shall be
held by Buyer in trust for the benefit of Seller and, promptly upon receipt by
Buyer of any such payment or reimbursement, Buyer shall pay over to Seller the
amount of such payment or reimbursement without right of set off, provided that
any such payment or reimbursement that is not paid by Buyer within 30 days of
receipt shall bear interest at a rate of 10% per annum until it is paid, which
interest, along with the principal amount of such payment or reimbursement,
shall be payable to Seller on demand.

Section 5.15      Agreements Regarding Tax Matters.

     5.15.1 Tax Returns. Seller and Buyer will each provide the other party with
such assistance as may reasonably be requested in connection with the
preparation of any Tax Return, audit or other examination by any taxing
authority or judicial or administrative proceeding relating to liability for
Taxes, will each retain and provide to the other party all records and other
information that may be relevant to any such Tax Return, audit or examination,
proceeding or determination and will each provide the other party with any final
determination of any such audit or examination, proceeding or determination that
affects any amount required to be shown on any Tax Return of the other party for
any period. Without limiting the generality of the foregoing, each of Buyer and
Seller will retain, until the expiration of the applicable statutes of

supporting work
<PAGE>

schedules and other records relating to tax periods or portions
thereof ending on or prior to the Closing Date.

     5.15.2 Sale. Buyer and Seller agree that the transactions contemplated by
this Agreement constitute a sale of a trade or business within the meaning of
Section 41(f)(3) of the Code. Seller will provide to Buyer upon request all
information necessary in order to permit Buyer to apply the provisions of
Section 41(f)(3)(A) of the Code.

     Section 5.16 Utilities. Buyer shall be responsible for all electric, gas,
telephone, water, sewer and similar utility charges relating to the Business
beginning on the Closing Date, and, with Seller's assistance, shall make such
arrangements with the utility service providers prior to the Closing for Buyer
to be charged directly for utility services beginning on such date. Seller shall
be responsible for all electric, gas, telephone, water, sewer and similar
utility charges relating to the Business prior to the Closing Date to the extent
not reserved or reflected as an Assumed Liability on the Final Closing Net Asset
Statement.

     Section 5.17 Notice to Buyer. Throughout the period between the date of
this Agreement and the Closing, Seller shall promptly notify Buyer in writing of
the occurrence of any event or development that comes to Seller's Knowledge
which has had or could reasonably be expected to have a Material Adverse Effect
on the Business, or any item or matter which would constitute a breach of the
representations and warranties of Seller contained in this Agreement or
affecting the ability of the parties to consummate the transaction contemplated
by this Agreement. No such notice will be deemed to have amended such Schedules,
to have qualified the representations and warranties contained herein and to
have cured any misrepresentations or breach of warranty that otherwise might
have existed hereunder by reason of such event or development.

     Section 5.18 Further Assurances. From time to time after the Closing, the
parties agree that each shall, at their own expense, execute and deliver, or
cause to be executed and delivered, such documents and instruments of title as
may be reasonably requested by the other in order more effectively to consummate
the transactions contemplated by this Agreement.

     Section 5.19 Public Announcements. All press releases, filings and other
public announcements concerning the transactions contemplated hereby will be
subject to review and approval by Seller or Buyer, as the case may be, such
approval not to be unreasonably withheld. Such approval shall not be required if
the party issuing such release, filing or public announcement reasonably
believes, based on advice of counsel, that it is required by law to do so, but
in any such case, all reasonable efforts shall be made to consult with the other
party in advance of such release, filing or announcement and to provide the
other party with the content thereof, the reasons the release, filing or
announcement is required by Law and the time and place that such release, filing
or announcement will be made.

     Section 5.20 Updates to Schedules. No later than two (2) business days
prior to the scheduled Closing Date, Seller and Elecsys shall amend or
supplement the Schedules delivered hereunder with respect to any matter which is
necessary to complete, update, or correct any information contained therein in
order to make the statements, representations and warranties contained in this
Agreement true and correct on the Closing Date or on a date as close to the

<PAGE>

Closing Date as is practical. As of the Closing Date, the representations and
warranties made by the Seller or Elecsys under this Agreement shall be read with
reference to the amended Schedules, and Buyer agrees that, to the extent of any
liability of Seller or Elecsys arising pursuant to a representation made herein,
the accuracy of the representations and warranties made by Seller or Elecsys
under this Agreement as of the Closing Date shall be evaluated after taking into
consideration the amended Schedules.

     Section 5.21 Exclusivity. From and after the date hereof unless and until
this Agreement shall have been terminated in accordance with its terms, Seller
will not (i) directly or indirectly solicit any Person, other than Buyer or any
of its Affiliates, involving the possible acquisition of the Business or any of
the Assets, (ii) subject to the obligations of the Board of Directors of Elecsys
to exercise its fiduciary duties, enter into discussions with any Person, other
than Buyer or any of its Affiliates, involving the possible acquisition of the
Business or any of the Assets, or (iii) subject to the obligations of the Board
of Directors of Elecsys to exercise its fiduciary duties, enter into any
transaction with any Person, other than Buyer or any of its Affiliates,
involving the possible acquisition of the Business, the Assets or the capital
stock of Seller. Seller will notify Buyer promptly if any person makes any
proposal, offer, inquiry or contact with respect to any of the foregoing.

Section 5.22      Non-Compete.

     5.22.1 Non-Compete. Except for the manufacturing agreement between DCI and
ASI contemplated by Sections 6.1.11 and 7.1.7 hereof, for a period of five (5)
years commencing on the Closing Date, Seller and Seller's Affiliates, and for a
period of three (3) years commencing on the Closing Date, Seller's directors and
Elecsys's officers and directors, shall not directly or indirectly, in any area
of the world, enter into, engage in, represent, furnish services to, or have any
interest in any business engaged in development, manufacture, marketing, sale,
maintenance or servicing of the products of the same general type as have been
developed, manufactured, marketed, sold, maintained or serviced in connection
with the Business either by Seller or Elecsys during the five (5) year period
ending on the Closing Date; provided, however, that Seller and Elecsys, their
officers or directors, and any of their Affiliates may acquire for passive
investment purposes any securities issued by entities which compete with the
Business so long as such equity securities constitute less than 5% of the voting
power represented by all outstanding equity securities of any such entity.
5.22.2 Remedies. Each of Seller and Elecsys acknowledges that in the event of
its or its affiliates' breach of the covenants contained in this Section 5.22,
money damages would be an inadequate remedy. Accordingly, without prejudice to
the rights of Buyer also to seek such damages or other remedies available to it,
Buyer may seek, and neither Seller nor Elecsys shall contest, the
appropriateness of the availability of injunctive or other equitable relief in
any proceeding that Buyer may bring to enforce the covenants contained in this
Section 5.22 in its express and explicit terms. No waiver of any breach of the
covenants contained in this Section 5.22 shall be implied from forbearance or
failure of Buyer to take action in respect thereof.

     5.22.3 Severability. The parties agree that, if any provision of this
Section 5.22 should be adjudicated to be invalid or unenforceable, such
provision shall be deemed deleted here from with respect, and only with respect,
to the operation of such provision in the particular
<PAGE>

jurisdiction in which such adjudication was made. To the extent any such
provision may be valid and enforceable in such jurisdiction by limitations on
the scope of the activities, geographical area or time period covered, the
parties agree that such provision instead shall be deemed limited to the extent,
and only to the extent, necessary to make such provision enforceable to the
fullest extent permissible under the laws and public policies in such
jurisdiction.

     Section 5.23 No Defaults. Seller will not commit or omit to take any act
that will cause a termination of or breach or default under any contract,
commitment or obligation to which Seller is a party or by which its assets are
bound, including the Contracts identified on Schedule 3.10.1, that could
reasonably be expected to have a Material Adverse Effect on the Business.

     Section 5.24 Compliance With Laws. Seller will use commercially reasonable
efforts to comply in the operation of the Business in all material respects with
all Laws and regulations applicable to the Business or the Assets or as may be
required for the valid and effective transfer to Buyer of the Assets.

     Section 5.25 Confidential Information. For a period of five (5) years after
the Closing Date, Seller and its Affiliates will treat and hold as such, and
will not use for the benefit of themselves or others, any confidential
information concerning the operations or affairs of the Business. In the event
Seller or any of its Affiliates is requested or required (by oral request or
written request for information or documents in any legal proceeding,
interrogatory, subpoena, civil investigative demand or similar process) to
disclose any such confidential information, then Seller will notify Buyer
promptly in writing of the request or requirement so that Buyer may seek an
appropriate protective order or waive compliance with this Section 5.25. If, in
the absence of a protective order or receipt of a waiver hereunder, Seller or
any of its affiliates is, on the advice of counsel, compelled by a court of
competent jurisdiction to disclose any confidential information concerning the
operations or affairs of the Business to any governmental entity, then Seller or
such affiliate may disclose such confidential information to such governmental
entity; provided, that Seller or such affiliate will use reasonable efforts to
obtain at the request and expense of Buyer an order or other assurance that
confidential treatment will be accorded to such confidential information. The
provisions of this Section 5.25 will not be deemed to prohibit the use of
confidential information concerning the operations or affairs of the Business by
Seller to the extent reasonably required to prepare any required Tax Returns or
financial statements or in connection with routine governmental audits of
corporate overhead expenses.

     Section 5.26 Solicitation of Employees. For a period of five (5) years from
the date hereof, neither of Seller or Elecsys will cause or permit any of its
affiliates, officers or directors to, solicit the employment of, offer
employment to or hire any executive, managerial, professional, technical or
engineering employee employed by Buyer in the Business; provided, however, that
the foregoing shall not apply to responses to or follow-up hiring in respect of
general solicitations or advertisements for job positions not specifically
directed to employees of the Business.

Section 5.27  Notice to Seller. Buyer agrees to notify Seller in writing,
promptly upon Buyer's or its authorized representatives' discovery, of any
information received by Buyer prior to the Closing Date relating to the Assets,
the Assumed Liabilities or the conduct of the Business
<PAGE>

which to the belief of Buyer constitutes (or would constitute) or indicates (or
would indicate) a breach of any representation, warranty or covenant made by
Seller herein.

     Section 5.28 Release of Liens on Assets under Credit Facilities. At or
prior to the Closing, Seller and Elecsys shall cause Bank of America to release
all Liens held by Bank of America on any and all of the Assets, whether owned at
that time by Seller or Elecsys. In addition, Seller and Elecsys shall cause Bank
of America to deliver to Buyer a letter stating that Bank of America has no Lien
on any of the Assets or any claim against Buyer for payment of any indebtedness
(the "Bank Letter"), which Bank Letter shall be delivered to Buyer at the
Closing.

     Section 5.29 Meeting of Shareholders. Elecsys shall take all action
necessary to call and hold a meeting of its shareholders at the earliest
practicable date after the date hereof, but in any event no later than August
30, 2001, for its shareholders to consider the transactions contemplated hereby.
Subject to their obligation to exercise their fiduciary duties, including those
as Directors of Elecsys, the Board of Directors of Elecsys shall inform all the
shareholders of Elecsys in the proxy materials relating to the meeting that, as
of the time such proxy materials are mailed to shareholders, each of the
Directors then presently intends to vote the shares of Elecsys which he
beneficially owns in favor of approving this Agreement. Subject to their
obligation to exercise their fiduciary duties, including those as Directors of
Elecsys, the Directors will recommend to the other shareholders of Elecsys that
they also vote their shares for such approval.

     Section 5.30 Seller's Access to Information. At the request of Seller (such

Indemnitor under this Agreement be liable for any Third Party Claim against any

Notice and the following conditions are satisfied:

     8.3.1 Timely Delivery of Claim Notice. Except as provided in Subsections
8.3.2 or 8.3.3, no right to indemnification under this Article VIII for a Third
Party Claim shall be available to an Indemnitee unless the Indemnitee shall have
delivered to the Indemnitor, not later than forty-five (45) days following the
date on which the Indemnitee shall have received written notice from the third
party of such Third Party Claim, a notice in writing describing in reasonable
detail the facts giving rise to such Third Party Claim and stating that the
Indemnitee intends to seek indemnification for such Third Party Claim from the
Indemnitor pursuant to this Article VIII (such notice, a "Claim Notice").

     8.3.2 Late Delivery of Claim Notice. If a Claim Notice is not given by the
Indemnitee within forty-five (45) days of receipt of such Third Party Claim as
provided in Subsection 8.3.1 hereof, the Indemnitee shall be entitled to be
indemnified under this Article VIII, except to the extent that the Indemnitor
can establish that the Indemnitor has been prejudiced by such time elapsed.

     8.3.3 Paid or Settled Claims. If a Claim Notice is not given by the
Indemnitee prior to the payment or settlement of a Third Party Claim, the
Indemnitee shall be entitled to be indemnified under this Article VIII except to
the extent that the Indemnitor can establish that the Indemnitor has been
prejudiced by such payment or settlement.

     Section 8.4 Defense of Claims. This section sets forth, among other things,
those circumstances in which the Indemnitor shall have the right to assume and
control the defense of an indemnified Third Party Claim and those in which the
Indemnitee shall have such right. Upon receipt of a Claim Notice from an
Indemnitee with respect to any Third Party Claim, the Indemnitor shall have the
right to assume and control the defense thereof (and any related settlement
negotiations) with counsel selected by the Indemnitor and reasonably
satisfactory to such Indemnitee (the "Indemnitor's Counsel"). The Indemnitee
shall cooperate in all reasonable respects in such defense. The Indemnitee shall
have the right to employ separate counsel at such Indemnitee's expense in any
action or claim and to participate in the defense thereof, including,
<PAGE>

without limitation, in any situation in which one or more defenses or one or
more counterclaims available to the Indemnitee conflict with one or more
defenses or one or more counterclaims available to the Indemnitor.

      Anything to the contrary in this Section 8.4 notwithstanding, the
Indemnitor shall not be entitled to control the defense of such Third Party
Claim (but shall be entitled to participate at its own expense in the defense
thereof) and the Indemnitee shall have the right to assume and control the
defense or settlement thereof with counsel of its own choosing reasonably
satisfactory to the Indemnitor (reasonable fees and expenses of such counsel
being at the expense of the Indemnitor), if: (i) the Indemnitor does not notify
the Indemnitee within thirty (30) days after receipt of the Claim Notice of its
intention to assume the defense of such Third Party Claim, (ii) such Third Party
Claim seeks an order, injunction, non-monetary or other equitable relief against
the Indemnitee which, if successful, could result in a Material Adverse Effect
upon the business, financial condition, results of operations or assets of the
Indemnitee, or (iii) the Indemnitor does not, or is unable to, fund the defense
of such Third Party Claim in the manner requested by Indemnitor's Counsel. With
respect to any settlement of such Third Party Claim, the Indemnitee shall send a
written notice to the Indemnitor of any proposed settlement of any such claim,
which settlement the Indemnitor may reject, in its reasonable judgment, within
thirty (30) days of receipt of such settlement. Failure to reject such notice
within such thirty-day period shall be deemed an acceptance of such notice and
proposed settlement.

     Section 8.5 Access and Cooperation. After the Closing Date, Buyer, on the
one hand, and Seller and Elecsys, on the other hand, shall (a) each cooperate
fully with the other as to all Third Party Claims, shall make available to the
other, as reasonably requested, all information, records and documents relating
to all Third Party Claims and shall preserve all such information, records and
documents until the termination of any Third Party Claim, and (b) make available
to the other, as reasonably requested and at the reasonable cost and expense of
the requesting party, personnel (including technical and scientific), ___ agents
and other representatives who are responsible for preparing or maintaining
information, records or other documents, or who may have particular knowledge
with respect to any Third Party Claim.

     Section 8.6 Assessment of Claims. In the event that any of the Losses for
which an Indemnitor is or is allegedly responsible pursuant to Sections 8.1 or
8.2 are recoverable or potentially recoverable against any third party at the
time when payment is due hereunder, following payment by the Indemnitor to the
Indemnitee for such Losses the Indemnitee shall assign any and all rights that
it may have to recover such Losses to the Indemnitor, or, if such rights are not
assignable under applicable law or otherwise, the Indemnitee shall attempt in
good faith to collect any and all Losses on account thereof from such third
party for the benefit of, and at the expense and direction of, the Indemnitor.

     Section 8.7 Limits on Indemnification.

     8.7.1 Limitations on Indemnification for Breach of Representations and
Warranties. Buyer Indemnitees shall not be entitled to seek payment under
Subsection 8.1.2(a), and Seller Indemnitees shall not be entitled to seek
payment under Subsection 8.2.2(a), in respect of any specific indemnified Loss
or Third Party Claim arising from a breach of a representation or warranty until
the aggregate total of such Losses and Third Party Claims under such
<PAGE>

Subsection 8.1.2(a), or Subsection 8.2.2(a), as applicable, is equal to or
exceeds $200,000 (the "Threshold Amount"), and then the Indemnitee(s) may seek
payment and indemnity from the Indemnitor for the full amount of the Loss or
Third Party Claim; provided, however, that neither the Buyer Indemnitees, with
respect to Subsection 8.1.2(a), nor the Seller Indemnitees, with respect to
Subsection 8.2.2(a), shall be entitled to seek payment thereunder to the extent
the aggregate total of such Losses and Third Party Claims exceeds $4,000,000
(the "Cap"), and, provided, further that the obligations of each of Seller and
Elecsys to pay and indemnify the Buyer Indemnitees pursuant to Section 8.1.2(a)
hereof on account of a breach by Seller or Elecsys of the representations and
warranties made pursuant to Subsections 3.5.1, 3.6.2, 3.15.2 and 3.15.5 hereof
shall not be subject to or reduced by the Threshold Amount or the Cap.

     8.7.2 No Limitations on Certain Indemnification Claims. The Buyer
Indemnitees may seek payment and full and complete indemnity from Seller and
Elecsys in respect of any and all Losses or Third Party Claims under Subsections
8.1.1, 8.1.2(b), 8.1.3 and 8.1.4, and the Seller Indemnitees may seek payment
and full and complete indemnity from Buyer in respect of any and all Losses or
Third Party Claims under Subsections 8.2.1 and 8.2.2(b) and such indemnity shall
not be subject to the Threshold Amount or the Cap.

     Section 8.8 Survival of Representations and Warranties. All representations
and warranties of the parties contained in this Agreement shall survive the
Closing hereunder and continue in full force and effect thereafter, regardless
of any investigation made or to be made by or on behalf of any party hereto, for
a period of fifteen (15) months following the Closing Date, except for the
representations and warranties (a) of Seller and Elecsys provided for (i) in
Sections 3.13, 3.14.3 and 3.15.5, which shall survive the Closing hereunder and
continue in full force and effect thereafter, regardless of any investigation
made or to be made by or on behalf of any party hereto, for a period ending
sixty (60) days after the expiration of the relevant statutes of limitations,
including with respect to representations and warranties regarding Taxes, any
extension or waiver thereof regarding the filing of Tax Returns and the payment
of Taxes, and (ii) in Sections 3.1, 3.2, 3.3.1, 3.6.2 and 3.20, which shall
survive the Closing hereunder and continue in full force and effect thereafter,
regardless of any investigation made or to be made by or on behalf of any party
hereto, without end or termination, and (b) of Buyer provided for in Sections
4.1, 4.2.1 and 4.5, which shall survive the Closing hereunder and continue in
full force and effect thereafter, regardless of any investigation made or to be
made by or on behalf of any party hereto, without end or termination. Except as
set forth in this Section 8.8, after the end of such period, an Indemnitor's
obligation to an Indemnitee under this Article VIII with respect to such
representations and warranties shall expire except with respect to a matter set
forth in a Claim Notice theretofore delivered by an Indemnitee. It is further
agreed that each Buyer Indemnitee's rights to indemnification set forth in
Subsections 8.1.1, 8.1.2(b), 8.1.3 and 8.1.4, and each Seller Indemnitee's
rights to indemnification set forth in Subsections 8.2.1 and 8.2.2(b), shall
remain in full force and effect indefinitely.

     Section 8.9 After-Tax Nature of Indemnity Payments. Any payment or
indemnity required to be made pursuant to Sections 8.1 or 8.2 hereof shall
include any amount necessary to hold the Indemnitee harmless on an after-tax
basis from all Taxes required to be paid with respect to the receipt of such
payment or indemnity (after taking into account any reduction in Taxes realized
by the Indemnitee as a result of the Loss giving rise to the payment or
indemnity). In determining the amount necessary to be added to any payment or
indemnity in order to
<PAGE>

accomplish the foregoing, the parties hereto agree (a) to treat all Taxes
required to be paid by, and all reductions in Tax realized by any Indemnitee, as
if such Indemnitee were subject to tax at the highest marginal tax rates (for
both federal and state, as determined on a combined basis) applicable to such
Indemnitee and (b) to treat any indemnification payments made to Buyer pursuant
to this Agreement as an adjustment to the Final Purchase Price, unless either
party receives a written opinion, reasonably satisfactory in form and substance
to the other party, of a law firm with appropriate experience and expertise to
the effect that it is not or is not likely to be permissible to treat such

herein, this Agreement may, by written notice given at or prior to the Closing
in the manner hereinafter provided, be terminated and abandoned only as follows:

     (a) By Seller or Buyer upon written notice if a material default or breach
shall be made by the other, with respect to the due and timely performance of
any of their respective covenants and agreements contained herein, or with
respect to the due compliance with any of their respective representations and
warranties contained in Article III or IV, as applicable, and such default
cannot be cured prior to Closing and has not been waived;

     (d) By Buyer in the event of a casualty or condemnation of the Owned
Property that has an Extreme Adverse Effect on the value of the Owned Property
or by Buyer pursuant to Subsection 5.31.3 hereof.

     Section 9.2 Effect of Termination. In the event this Agreement is
terminated pursuant to Section 9.1, all further rights and obligations of the
parties hereunder shall terminate, except that the obligations set forth in the
Confidentiality Agreement shall survive; it being specifically agreed that, if
this Agreement is so terminated by either Buyer or Seller, because one or more
of the conditions to such party's obligations hereunder is not satisfied as a
result of the other such party's failure to comply with its obligations under
this Agreement, it is expressly agreed and understood that the rights of the
terminating party to pursue all legal remedies for breach of contract and
damages shall survive such termination and the breaching party shall be fully
liable for any and all damages, costs and expenses sustained or incurred by the
terminating party as a result of such breach.

     Section 9.3 Fees and Expenses. Except as otherwise provided in Section 9.2
hereof, each party shall be responsible for its own costs, fees and expenses,
including fees and expenses of its accountants, investment advisors and counsel.

     Section 10.1 Remedies. The remedies expressly set forth in this Agreement
following the Closing with respect to any breach of any representation or
warranty herein contained, are the sole and exclusive remedies for any such
breach, and are intended to be non-cumulative with respect to any other remedies
which would otherwise have been available in common law or by statute. No party
shall have the right after the Closing to assert any cause of action or make any
claim to recover or seek any relief on any basis other than as expressly
provided under this Agreement; provided, however, that nothing contained in this
Agreement shall constitute a waiver by or limitation on any party hereto to
institute any cause of action (whether in law or in equity) against the other
for (i) fraud, bad faith or intentional misrepresentation or (ii) specific
performance under applicable law (including injunction, declarative or
otherwise) or (iii) breach of any covenant contained herein.

delivered by each of the parties hereto, be binding upon and for the benefit of
