ITEM 2.       ACQUISITION OR DISPOSITION OF ASSETS

      On February  7, 2000,  Airport  Systems  International,  Inc.,  a Kansas
corporation  ("ASII"),  acquired all of the issued and  outstanding  shares of
common  stock,  $1.00 par value  per  share,  and  certain  intangible  assets
relating to DCI, Inc., a Kansas  corporation  ("DCI"),  from its stockholders,
Chris I. Hammond,  Larry C. Klusman and William D. Cook (the  "Sellers").  DCI
is an  electrical  contract  manufacturing  company.  ASII intends to continue
the operations of DCI.

      ASII paid $1,234,000 in cash, issued 150,000 shares of its common stock
and delivered a four-year promissory note in the amount of $1,248,000 in
consideration for the common stock and intangible assets acquired from Sellers.
The total consideration for the acquisition from the Sellers was $2,819,500,
plus the assumption of certain debt owed by DCI.

      Immediately following the acquisition of the common stock and intangible
assets of DCI, DCI acquired certain assets of KHC of Lenexa, L.L.C., a Kansas
limited liability company ("KHC"). KHC was owned by the Sellers and had a
leasehold interest in certain real property that was the subject of City of
Lenexa, Kansas Variable Rate Demand Industrial Development Revenue Bonds (DCI
Project) Series 1998 totaling $2,570,000 and other related documents (the "IRB
Documents"). DCI paid $1,290,000 in cash as consideration for the assets
acquired from KHC. DCI also assumed certain liabilities and obligations related
to the IRB Documents.

      The asset and stock acquisitions were financed through a Loan and Security
Agreement entered into by and among ASII, DCI and Bank of America, N.A. ("BOA")
as of February 7, 2000, providing, among other things, a revolving loan in the
amount of $8,000,000, term loans from BOA in the amount of $1,178,000 and an
irrevocable direct-pay letter of credit facility in the amount of $2,599,572.60.

      On February 7, 2000, ASII also entered into a financing arrangement with
KCEP Ventures II, L.P., a Kansas limited partnership ("KCEP"). In connection
with this arrangement, ASII sold and issued to KCEP 198,413 shares of ASII
common stock for $500,000 ($2.52 per share), a convertible subordinated
debenture in an amount of $500,000 with a conversion price of $3.00 per share,
and a warrant granting KCEP the right to purchase 45,635 shares of ASII common
stock for $150,595.50 ($3.30 per share). ASII plans to use the proceeds from the
sale of the securities for general working capital purposes and to fund
potential future acquisitions in the electrical contract manufacturing business.

      The Stock Purchase Agreement with Sellers, the Asset Purchase Agreement
with KHC, the Investment Agreement with KCEP, the Loan and Security Agreement
with BOA and the press release issued by ASII in connection with the acquisition
and financing are filed as exhibits to this report and are incorporated herein
by reference. The description of the acquisition and financing set forth herein
does not purport to be complete and is qualified by the provisions of the
agreements noted above and attached hereto.

consent from, action by or in respect of, or filing with, any court, arbitrator
or any local, state, federal or foreign governmental or regulatory authority,

relating thereto. There is no lawsuit or legal, administrative or regulatory
proceeding or investigation pending or threatened against the Seller challenging

     2.7. ASSETS. Except for the Real Property, which is leased by Seller
pursuant to the IRB Documents, Seller is the sole and exclusive legal and
equitable owner of, and has good and marketable title to the Assets free and
clear of any encumbrance. To the best knowledge of Seller, the Real Property and
the Improvements are in good condition and repair, are free from material
defect, are adequate and sufficient for use as the principal place of business
for the business operations currently conducted by Buyer, and are in compliance
with applicable Laws and industry standards. No portion of the Real Property or

          thereto), other than the covenants or restrictions set forth in the
          Lease;

               (iii) the Assets other than the Real Property are not subject to

          thereto), other than such covenants or restrictions set forth in the

          further assurances with respect to this representation and warranty as
          Buyer shall reasonably request;

               (vii) Other than the Lease, Seller has no interest as lessor or
          lessee in leases of or for all or any portion of the Real Property or
          the Improvements;

     9.2. INDEMNIFICATION BY THE SELLER. The Seller and its Members shall be
jointly and severally responsible to assume the defense of, and indemnify and
hold the Buyer, its affiliates and their directors, officers and employees
(collectively, the "Buyer Group") harmless from, any and all losses, damages,
costs and expenses (including, without limitation, court costs and reasonable
outside attorneys' and accountants' fees) (hereinafter individually, a "Loss"
and collectively, "Losses") suffered or incurred by any member of the Buyer
Group that relate to, or arise out of or in connection with (i) any breach of
any representation or warranty made by the Seller contained in this Agreement;
(ii) a breach of any other covenant or agreement by the Seller contained in this
Agreement; or (iii) any liability against the Buyer or the Assets arising as a
result of events occurring or circumstances existing prior to the Closing Date.

     9.3. INDEMNIFICATION BY THE BUYER. The Buyer shall be responsible to assume
the defense of, and indemnify and hold the Seller, its affiliates and the
Members, officers and employees (collectively, the "Seller Group") harmless
from, any and all losses, damages, costs and expenses (including, without
limitation, court costs and reasonable outside attorneys' and accountants' fees)
(hereinafter individually, a "Loss" and collectively, "Losses") suffered or
incurred by any member of the Seller Group that relate to, or arise out of or in
connection with (i) any breach of any representation or warranty made by the
Buyer contained in this Agreement; (ii) a breach of any other covenant or
agreement by the Buyer contained in this Agreement; (iii) any liability against
the Seller Group or the Assets arising as a result of events occurring or
circumstances existing after the Closing Date.

     9.4. CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for
indemnification under this Section 9, the Buyer or the Seller, as the case may
be, seeking indemnification (the "Indemnified Party"), shall promptly notify the
other party (the "Indemnifying Party") of the claim and, when known, the facts
constituting the basis for such claim. In the event of any such claim for
indemnification hereunder resulting from or in connection with any claim or
legal proceedings by a third party, the notice shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom. The
Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent, which shall not be unreasonably withheld or delayed, of the
Indemnifying Party; provided, however, that if suit shall have been instituted
against the Indemnified Party and the Indemnifying Party shall not have taken
control of such suit after notification thereof as provided in Section 9.5 of
this Agreement, the Indemnified Party shall have the right to settle or
compromise such claim upon giving notice to the Indemnifying Party as provided
in Section 9.5.

     9.5. DEFENSE BY THE INDEMNIFYING PARTY. In connection with any claim which
may give rise to indemnity hereunder resulting from or arising out of any claim
or legal proceeding by a person other than the Indemnified Party, the
Indemnifying Party, at the sole cost and expense of the Indemnifying Party, may,
upon written notice to the Indemnified Party, assume the defense of any such
claim or legal proceeding if the Indemnifying Party acknowledges to the
Indemnified Party in writing the obligation of the Indemnifying Party to
indemnify the Indemnified Party with respect to all elements of such claim. If
the Indemnifying Party assumes the defense of any such claim or legal
proceeding, the Indemnifying Party shall select counsel reasonably acceptable to
the Indemnified Party to conduct the defense of such claims or legal proceedings
and at the sole cost and expense of the Indemnifying Party shall take all steps
necessary in the defense or settlement thereof. The Indemnified Party shall
thereafter be entitled

                                       18
<PAGE>

to participate in and assume control of the defense of any such action if the
Indemnified Party has a reasonable basis for concluding that its interests would
be better served. The Indemnifying Party shall not consent to a settlement of,
or the entry of any judgment arising from, any such claim or legal proceeding,
without the prior written consent of the Indemnified Party (which consent shall
not be unreasonably withheld or delayed). The Indemnified Party shall be
entitled to participate in (but not control) the defense of any such action,
with its own counsel and at its own expense. If the Indemnifying Party does not
assume the defense of any such claim or litigation resulting therefrom within 30
days after the date such claim is made: (a) the Indemnified Party may defend
against such claim or litigation in such manner as it may deem appropriate,
including, but not limited to, settling such claim or litigation, after giving
notice of the same to the Indemnifying Party, on such terms as the Indemnified
Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to
participate in (but not control) the defense of such action, with its counsel
and at its own expense. If the Indemnifying Party or the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third party
claim in a reasonably prudent manner.

            (a) EMPLOYEE PLANS. SCHEDULE 2.24 attached hereto contains a true,
      correct and complete list of all pension, benefit, profit sharing,
      retirement, deferred compensation, welfare, insurance, disability, bonus,
      vacation pay, severance pay and other similar plans, programs and

      to the employees of the Company, or maintained at any time since January
      1, 1997 by the Company or by any member of any controlled group of
      corporations, group of trades or businesses under common control, or
      affiliated service group (as defined for purposes of Section 414(b), (c)
      and (m), respectively, of the Code) (the "Company Employee Plans") of
      which it is or has been a member which shall be referred to herein as a

      obligation to contribute to, any stock option or stock purchase plan or
      other plan designed to hold the stock of the Company or any of its
      affiliates. No employee of the Company participates in an Employee Plan
      that is sponsored or maintained by an entity other than the Company and no
      one other than Company employees and their beneficiaries or dependents
      participate in an Employee Plan sponsored or maintained by the Company.

          (b) PROHIBITED TRANSACTIONS. Neither the Company nor any of its
     directors, officers, employees or agents, or any "party in interest" or
     "disqualified person", as such terms are defined in Section 3 of the
     Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and
     Section 4975 of the Code has, with respect to any Employee Plan, engaged in
     or been a party to any nonexempt "prohibited transaction", as such term is
     defined in Section 4975 of the Code or Section 406 of ERISA, in connection
     with which, directly or indirectly, the Buyer or any of its affiliates,
     directors or employees or

                                       14
<PAGE>

     any Employee Plan or any related funding medium could be subject to either
     a penalty assessed pursuant to Section 502(i) of ERISA or a tax imposed by
     Section 4975 of the Code.

          (c) COMPLIANCE. To the best knowledge of Sellers, with respect to all
     Company Employee Plans, the Company is in compliance with the terms of the
     plans and the requirements prescribed by any and all statutes, orders or
     governmental rules or regulations currently in effect, including, but not
     limited to, ERISA and the Code, applicable to such Company Employee Plans.
     To the best knowledge of Sellers, the Company has in all respects performed
     all obligations required to be performed by it under, and is not in
     violation in any respect of, and there has been no default or violation by
     any other party with respect to, any of the Company Employee Plans. Except
     as set forth on SCHEDULE 2.24, none of the Company Employee Plans which are
     subject to Title IV of ERISA has been or will be terminated in whole or in
     part within the meaning of ERISA or the Code; no liability has been
     incurred to, nor has any event or circumstance occurred, nor will any event
     or circumstance occur prior to the Closing Date, which could result in such
     a liability being asserted by, the Pension Benefit Guaranty Corporation
     with respect to any Company Employee Plan (other than the payment of annual
     premiums under Section 4007 of ERISA); nor has any Company Employee Plan
     that is subject to Part 3 of Subtitle B of Title I of ERISA or Section 412
     of the Code, or both, incurred any "accumulated funding deficiency" (as
     defined in ERISA), whether or not waived; nor has the Company failed to pay
     any amounts due and owing as required by the terms of any Company Employee
     Plan; nor has there been any "reportable event" within the meaning of
     Section 4043(b)(l)-(9) of ERISA, or any event described in Section 4063(a)
     of ERISA, with respect to any Company Employee Plan, other than as
     disclosed herein or on accompanying schedules.

          (d) MULTI EMPLOYER PLANS. Except as set forth on SCHEDULE 2.24,
     neither the Company nor any Member of the Controlled Group has ever been
     obligated to contribute to any "multi employer plan", as such term is
     defined in Section 3(37) of ERISA. Neither the Company nor any Member of
     the Controlled Group has any "withdrawal liability", as computed under
     Section 4211 of ERISA, with respect to any such plan and the Company and
     each Member of the Controlled Group has made all contributions to any such
     plan as are required through the Closing Date under the terms of any such
     plans or applicable statutes, regulations, rulings and other applicable
     law; and no event has occurred, or can occur prior to the Closing Date,
     which could give rise to any other liability (other than a continuing
     obligation to contribute to such plan(s) under the terms of any applicable
     collective bargaining agreements) on the part of the Company or any Member
     of the Controlled Group, the Buyer, or their affiliates, officers,
     employees or directors with respect to such plan(s).

          (f) QUALIFICATIONS. Each Company Employee Plan and all amendments
     thereto intended to qualify under Section 401(a) of the Code have been
     determined by the Internal Revenue Service to so qualify, and the trusts
     created thereunder have been determined to be exempt from tax under the
     provisions of Section 501(a) of the Code, and copies of all determination
     letters with respect to each such Company Employee Plan have been
     previously delivered by the Sellers or the Company to the Buyer, and
     nothing has since occurred, or will occur prior to the Closing Date, which
     might cause the loss of such qualification or exemption, no such Company
     Employee Plan has been operated in a manner which would cause it to be
     disqualified in operation, and all such Company Employee Plans have been
     administered in compliance with and consistent with all applicable
     requirements of the Code and ERISA, including, without limitation, all
     reporting and disclosure requirements.

          Benefit Plan.

               (ii) With respect to each Company Employee Plan which is a
          qualified profit-sharing or stock bonus plan, as defined in ERISA, all
          employer contributions accrued for plan years ending prior to the
          Closing Date under the Company Employee Plan terms and applicable law
          have been made by the Company.

               (iii) All premiums or other payments required by the terms of any

     to employment or continued employment with the Buyer, the Company, or any
     successor or affiliate; nor shall the Buyer, the Company or their
     affiliates be precluded or prevented from terminating or amending any
     Company Employee Plan.

          (j) TRANSFER. The Company shall take any actions as may be necessary
     or appropriate in the reasonable opinion of the Buyer and the Buyer's
     counsel under all applicable laws and the terms of the Company Employee

<PAGE>

     9.1 BY THE SELLERS AND THE COMPANY. If the Closing occurs, the Sellers and
the Company hereby indemnify and hold harmless the Buyer, from and against all
claims, damages, losses, liabilities, costs and expenses (including, without
limitation, settlement costs and any legal, accounting or other expenses for
investigating or defending any actions or threatened actions) (collectively, the
"Losses") in connection with each and all of the following:

          (a) any material misrepresentation or breach of any representation or
     warranty made by the Sellers and the Company in this Agreement;

          (b) any material breach of any covenant, agreement or obligation of
     the Sellers and the Company contained in this Agreement or any other
     agreement, instrument or document contemplated by this Agreement;

          (c) any misrepresentation contained in any statement, certificate or
     schedule furnished by the Sellers and the Company pursuant to this
     Agreement or in connection with the transactions contemplated by this
     Agreement; and

          (d) any claim relating to the Company's business or operation prior to
     the Closing Date, other than any warranty or other claim relating to a
     product manufactured or sold by the Company prior to the Closing Date.

     9.2 BY THE BUYER. If the Closing occurs, the Buyer hereby indemnifies and
holds harmless the Sellers and the Company, from and against all claims,
damages, losses, liabilities, costs and expenses (including, without limitation,
settlement costs and any legal, accounting or other expenses for investigating
or defending any actions or threatened actions) (collectively, the "Losses") in
connection with each and all of the following:

          (a) any misrepresentation or breach of any representation or warranty
     made by the Buyer in this Agreement;

          (b) any breach of any covenant, agreement or obligation of the Sellers
     contained in this Agreement or any other agreement, instrument or document
     contemplated by this Agreement;

          (c) any misrepresentation contained in any statement, certificate or
     schedule furnished by the Buyer pursuant to this Agreement or in connection
     with the transactions contemplated by this Agreement; and

          (d) any claim relating to (i) products manufactured or sold by the
     Company after the Closing Date or (ii) the Company's business or operation
     after the Closing Date.

     9.3 CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for
indemnification under this Section 9, the Buyer, the Sellers or the Company, as
the case may be, seeking indemnification (the "Indemnified Party"), shall
promptly notify the other party (the "Indemnifying Party") the claim and, when
known, the facts constituting the basis for such claim. In the event of any such
claim for indemnification hereunder resulting from or in connection with any
claim or legal proceedings by a third party, the notice shall specify, if known,
the amount or an estimate of the amount of the liability arising therefrom. The

                                       32
<PAGE>

Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent, which shall not be unreasonably withheld or delayed, of the
Indemnifying Party; provided, however, that if suit shall have been instituted
against the Indemnified Party and the Indemnifying Party shall not have taken
control of such suit after notification thereof as provided in Section 9.3 of
this Agreement, the Indemnified Party shall have the right to settle or
compromise such claim upon giving notice to the Indemnification Party as
provided in Section 9.3.

     9.4 DEFENSE BY THE INDEMNIFYING PARTY. In connection with any claim which
may give rise to indemnity hereunder resulting from or arising out of any claim
or legal proceeding by a person other than the Indemnifying Party, at the sole
cost and expense of the Indemnifying Party, may, upon written notice to the
Indemnified Party, assume the defense of any such claim or legal proceeding if
the Indemnifying Party acknowledges to the Indemnified Party in writing the
obligation of the Indemnifying Party to indemnify the Indemnified Party with
respect to all elements of such claim. If the Indemnifying Party assume the
defense of any such claim or legal proceeding, the Indemnifying Party shall
select counsel reasonably acceptable to the Indemnified Party to conduct the
defense of such claims or legal proceedings and at the sole cost and expense of
the Indemnifying Party shall take all steps necessary in the defense or
settlement thereof. The Indemnified Party shall thereafter be entitled to
participate in and assume control of the defense of any such action if the
Indemnified Party has a reasonable basis for concluding that its interests would
be better served. The Indemnifying Party shall not consent to a settlement of,
or the entry of any judgment arising from, any such claim or legal proceeding,
without the prior written consent of the Indemnified Party (which consent shall
not be unreasonably withheld or delayed). The Indemnified Party shall be
entitled to participate in (but not control) the defense of any such action,
with its own counsel and at its own expense. If the Indemnifying Party do not
assume the defense of any such claim or litigation resulting therefrom within 30
days after the date such claim is made: (a) the Indemnified Party may defend
against such claim or litigation in such manner as it may deem appropriate,
including, but not limited to, settling such claim or litigation, after giving
notice of the same to the Indemnifying Party, on such terms as the Indemnified
Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to
participate in (but not control) the defense of such action, with its counsel
and at its own expense. If the Indemnifying Party or the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third party
claim in a reasonably prudent manner.

     9.5 PAYMENT OF INDEMNIFICATION OBLIGATION. All indemnification by the
Buyer, Sellers or the Company hereunder, as the case may be (to the extent not
satisfied in the manner specified in the preceding sentence), and any
indemnification by the Sellers, Buyer or the Company, as the case may be, if the
Closing does not occur, shall be effected by payment of cash or delivery of a
cashier's or certified check in the amount of the indemnification liability.
Buyer shall, in addition to other remedies then available to it, have the right
to offset the amount of such indemnification claim against payments due from
Buyer to Seller. Buyer shall only be entitled to receive payment for Losses for
which it is otherwise entitled to be compensated under this Section 9 to the
extent such Losses in the aggregate exceed $25,000 (the "Basket Amount"). If
such Losses in the aggregate exceed the Basket Amount, Buyer shall be entitled
to payment of all losses pursuant to this Section 9 that are in excess of the
Basket Amount.

                                       33

     9.6 SURVIVAL OF REPRESENTATIONS. All representations and warranties made by
the Sellers and the Company in this Agreement, or in any instrument or document
furnished in connection with this Agreement or the transactions contemplated
hereby, excluding those listed below, shall survive the Closing and any
investigation at any time made by or on behalf of the Indemnified Party for a
period of eighteen months. The representations and warranties provided in
Section 2.18 shall survive the Closing and any investigation at any time made by
or on behalf of the Indemnified Party for a period of three (3) years. The
representations and warranties provided in Section 2.22 shall survive the
Closing and any investigation at any time made by or on behalf of the
Indemnified Party for a period of five (5) years.

further obligation or liability to the Buyer under this Agreement.

     10.3 TERMINATION BY REASON OF BREACH. This Agreement may be terminated by

may be terminated by the Buyer, if at any time prior to the Closing there shall
occur a material breach of any of the representations, warranties or covenants
of the Sellers, the Company or the failure of the Sellers, or the Company to
perform any condition or obligation hereunder.

     10.4 AVAILABILITY OF REMEDIES AT LAW. In the event this Agreement is

subordinated  debenture  (the  "Convertible  Subordinated  Debenture")  in  an
amount  of  $500,000,  with  a  conversion  price  of  $3.00  per  share  (the
"Debenture  Price"),  in substantially  the form attached hereto as Exhibit A;
and

                  (c) WARRANT. A warrant (the "Warrant") granting Purchaser the

and conditions of this Agreement, Company will execute and deliver to Purchaser,
and Purchaser will acquire, at the Closing (as defined in Section 2 below), the

the "Securities."

            1.5   USE OF PROCEEDS.

                  (a) WORKING CAPITAL. Company will use the proceeds from the
sale of the Securities for general working capital purposes and to fund

acquisition plan, attached hereto as Exhibit C, agreed to between Company and
Purchaser. Pending such use, Company shall place such proceeds in one or more
federally insured deposit accounts.

                  (b) LIMITATIONS. Notwithstanding anything herein to the
contrary, no portion of the proceeds from the sale of the Securities sold will
be used (i) for relending or reinvesting, if Company's primary purpose involves,
directly or indirectly, providing funds to others, (ii) for the purchase of debt
obligations, factoring, or the long-term leasing of equipment with no provision
for maintenance or repair, (iii) to, directly or indirectly, provide capital or
financing to a company licensed under the Small Business Investment Act of 1958,
as amended (together with the rules and regulations thereunder, the "SBI Act"),
(iv) to acquire, or to pay obligations relating to the prior acquisition of,
land or improved real estate to be held, without prompt and substantial
improvement, for resale or leasing to others, (v) outside the United States
(except that all or any portion of such proceeds may be used by Company in the
domestic production of products for distribution abroad or to acquire abroad
materials used in such production, provided the major portion of the assets and
activities of Company after such proceeds are so employed remains within the
territorial jurisdiction of the United States), (vi) for any purpose contrary to
the public interest (including but not limited to activities which are in


                                       -2-
<PAGE>

violation of law or inconsistent with free competitive enterprise), (vii) to
purchase goods or services from a supplier that is an "associate" (as defined in
Section 107.50 of Title 13 of the Code of Federal Regulations (the "CFR")) of
Purchaser if 50% or more of such proceeds will be used to purchase goods or
services from any such supplier (provided, however, that (A) in no event may
such proceeds be used to purchase capital goods from an associate supplier, and
(B) such goods and services shall be at a price no greater than that charged
other customers of the associate supplier), or (viii) to acquire "farm land" (as
that term is defined in Section 107.720 of Title 13 of the CFR).

                  (c) UNAUTHORIZED DIVERSION. Unless specifically consented to
by Purchaser, any (i) diversion by Company of the proceeds from the sale of the
Securities from the purposes set forth in this Section 1.5 or (ii) change in
Company's business activity within the 12-month period following the Closing (as
defined in Section 2 below) that renders the Securities an ineligible investment
for Purchaser pursuant to Section 107.760(b) of Title 13 of the CFR shall
constitute an event of default under this Agreement. Upon the occurrence of such
event of default, Purchaser shall have the right to demand immediate repurchase
of, and Company shall immediately repurchase, (i) all the Common Stock acquired
pursuant to Section 1.2 above and held by Purchaser, at a per share purchase
price equal to $2.52, (ii) the Convertible Subordinated Debenture held by
Purchaser, at face value plus all accrued interest thereon, (iii) any shares of
Common Stock held by Purchaser as a result of the conversion of the Convertible
Subordinated Debenture, at a per share purchase price equal to $3.00 for any
Common Stock issued to Purchaser, and (iv) any purchased and issued Common Stock
acquired pursuant to the Warrant, at a per share purchase price equal to $3.30.
In addition, the Warrant shall be cancelled.

      2.    THE CLOSING.

            2.1 THE CLOSING. The closing of the sale and purchase of the Common
Stock, Convertible Subordinated Debenture and the Warrant (the "Closing") under
this Agreement shall take place at the offices of Blackwell Sanders Peper Martin

64108 at 10:00 a.m., Central Time, on February 7, 2000 (the "Closing Date"), or
at such other time, date and place as are mutually agreeable to Company and
Purchaser, but in no event later than 5:00 p.m., Central Time, on March 15,
2000. At the Closing, Company will deliver to Purchaser a certificate or
certificates for 198,413 Common Stock shares registered in the name of Purchaser
against receipt by Company, as consideration, of the Common Stock Purchase Price
by wire transfer, check, or other method acceptable to Company. At the Closing,
Company will deliver to Purchaser the Convertible Subordinated Debenture in the
name of the Purchaser against receipt by Company, as consideration, of the
Debenture Price, by wire transfer, check or other method acceptable to Company.
At the Closing, Company will deliver to Purchaser the Warrant in the name of the
Purchaser. In addition, the Company will pay the Purchaser a commitment fee in
the amount of $20,000 at the Closing.

            2.2 If at Closing any of the applicable conditions specified in
Section 5 hereof shall not have been fulfilled, Purchaser shall, at its
election, be relieved of its obligations to purchase Securities at such Closing
without thereby waiving any other rights it may have by reason of such failure
or such non-fulfillment.

                                       -4-
<PAGE>

conversion and exercise of the Convertible Subordinated Debenture and the
Warrant, respectively, shall not result in any loss by the Purchaser of the
right to vote as a stockholder of the Company any shares of common stock
acquired hereunder pursuant to the provisions set forth in section 17-1286 et.
al, Control Shares Acquisitions, of the Kansas statutes.

            3.5 ISSUANCE OF SECURITIES. The issuance, sale, and delivery of the

Subordinated Debenture and exercise of the Warrant, have been or will be, on or
prior to the applicable Closing, duly authorized and reserved for issuance, as
the case may be, by all necessary corporate action on the part of Company, and
the shares when so issued, sold, and delivered against payment therefor in
accordance with the provisions of this Agreement, and the shares of Common Stock
issuable upon conversion or exercise of the Convertible Subordinated Debenture,
when issued upon such conversion or exercise, will be duly and validly issued,
fully paid, and nonassessable.

            3.6 AUTHORITY FOR AGREEMENT. The execution, delivery, and
performance by Company of this Agreement and all other agreements required to be
entered into pursuant to this Agreement have been or will be, on or prior to the
applicable Closing, duly authorized by all necessary corporate action, and duly
executed and delivered by Company. This Agreement and such other agreements
constitute valid and binding obligations of Company enforceable in accordance
with their respective terms. The execution and performance of the transactions
contemplated by this Agreement and such other agreements to be executed and
delivered by Company hereunder and compliance with their provisions by Company
will not violate any provision of law and will not conflict with or result in
any breach of any of the terms, conditions or provisions of, or constitute a
default under, its Articles of Incorporation or bylaws, any indenture, lease,
agreement, or other instrument to which Company is a party or by which it or any
of its properties is bound, or any decree, judgment, order, statute, rule or
regulation applicable to Company.

            3.7 GOVERNMENTAL CONSENTS. No consent, approval, order, or
authorization of, or registration, qualification, designation, declaration, or
filing with, any governmental authority is required on the part of Company in
connection with the execution and delivery of this Agreement, the offer, issue,
sale and delivery of the Securities, or the other transactions to be consummated
at the applicable Closing, as contemplated by this Agreement, except such
filings as shall have been made prior to and shall be effective on and as of
such Closing. Based on the representations made by Purchaser in Section 4 of
this Agreement, the offer and sale of the Securities to Purchaser will be exempt
from registration under applicable federal and state securities laws.

only to a person or entity acquiring at least that portion of the Securities

<PAGE>

stating the name and address of the transferee and identifying the securities
with respect to which such rights are being assigned; AND, PROVIDED FURTHER that
the transferor shall only retain such rights if, following the transfer, the
transferor retains not less than such threshold amount of the Securities.

                  (b) TRANSFEREES. Any transferee to whom rights under Section 7
are transferred shall, as a condition to such transfer, deliver to Company a
written instrument by which such transferee agrees to be bound by the

such transferee were Purchaser hereunder.

in connection with the review of this Agreement and the closing of the

the Purchaser, its officers, directors, agents, attorneys, and affiliates, and
their respective successors and assigns, from and against any loss, damage, or

                  (a) any breach or default in the performance by the Company of
any covenant or agreement of the Company contained in this Agreement or in any
agreement executed in conjunction herewith or transaction contemplated hereby;

                  (b) any breach of any representation or warranty made by the
Company herein, in any Exhibit hereto, or in any certificate or other instrument
delivered by the Company pursuant hereto; or

                  (c) any liability arising out of any and all actions, suits,
proceedings, claims, demands, judgments, costs and expenses (including
reasonable legal and accounting fees) incident to any of the foregoing.

            16.2 INDEMNIFICATION BY PURCHASER. The Purchaser hereby indemnifies
and holds harmless, for a period of eighteen (18) months from the date hereof,
the Company, its officers, directors, agents, attorneys and affiliates, and

expense (including reasonable attorneys' fees) caused by or arising out of:


                                      -17-
<PAGE>

                  (a) any breach of any representation or warranty made by the
Purchaser herein, in any Exhibit hereto, or in any certificate or other
instrument delivered by the Purchaser pursuant hereto; or

                  (b) any liability arising out of any and all actions, suits,
proceedings, claims, demands, judgments, costs and expenses (including
reasonable legal and accounting fees) incident to the foregoing.

            16.3 CONDITIONS OF INDEMNIFICATION. The respective obligations and
liabilities of the Company and the Purchaser to the other under Sections 16.1
and 16.2 hereof with respect to claims resulting from the assertion of liability
by third parties shall be subject to the following terms and conditions:

                  (a) within 10 days (or such earlier time as might be required
to avoid prejudicing the indemnifying party's position) after receipt of notice
of commencement of any action evidenced by service of process or other legal
pleading, or with reasonable promptness after the assertion in writing of any
claim by a third party, the party to be indemnified shall give the indemnifying
party written notice thereof together with a copy of such claim, process, or
other legal pleading, and the indemnifying party shall have the right to
undertake the defense thereof by representatives of its own choosing and at its
own expense; provided, however, that the party to be indemnified may participate
in the defense with counsel of its own choice and at its own expense.

                  (b) in the event that the indemnifying party, by the 30th day
after receipt of notice of any such claim (or, if earlier, by the 10th day
preceding the day on which an answer or other pleading must be served in order
to prevent judgment by default in favor of the person asserting such claim),
does not elect to defend against such claim, the party to be indemnified will
(upon further notice to the indemnifying party) have the right to undertake the
defense, compromise or settlement of such claim on behalf of and for the account
and risk of the indemnifying party and at the indemnifying party's expense,
subject to the right of other indemnifying party to assume the defense of such
claims at any time prior to settlement, compromise or final determination
thereof.

                  (c) anything in this Section 16.3 to the contrary
notwithstanding, the indemnifying party shall not settle any claim without the
consent of the party to be indemnified unless such settlement involves only the
payment of money and the claimant provides to the party to be indemnified a
release from all liability in respect of such claim. If the settlement of the
claim involves more than the payment of money, the indemnifying party shall not
settle the claim without the prior consent of the party to be indemnified, which
consent shall not be unreasonably withheld.

                  (d) the party to be indemnified and the indemnifying party
will each cooperate with all reasonable requests of the other.

      17.   ENTIRE  AGREEMENT.  This Agreement  embodies the entire  agreement
and  understanding  between  the parties  hereto  with  respect to the subject
matter hereof and supersedes all prior agreements and understandings  relating
to such subject matter.

accordance with this Section 18 shall be binding upon each holder of any
Securities (including shares of Common Stock into which such Securities have
been converted), each future holder of all such securities, and Company. No
waivers of or exceptions to any term, condition, or provision of this Agreement,

breach of this Agreement may cause irreparable injury to the one or more of the

inadequate remedy and agrees that, in such event, the respective rights and
obligations hereunder shall be enforceable by specific performance, injunction,

            (b) REVOLVING CREDIT LOAN B. Upon the terms and subject to the
conditions of, and in reliance upon the representations and warranties made
under, this Agreement, the Lender shall make Revolving Credit Loans to the
Borrower from time to time from the Effective Date to the Termination Date, as
requested by the Borrower in accordance with the terms of SECTION 2A.3, in an
aggregate principal amount outstanding not to exceed at any time the LEAST OF
(a) Three Million and No/100 Dollars ($3,000,000.00); (b) the Revolving Credit
Loan B Borrowing Base and (c) an amount which, when added to the
then-outstanding balance of Revolving Credit Loan A would exceed the Revolving
Credit Facility. It is expressly understood and agreed that the Lender may and
at present intends to use the lesser of the amounts referred to in the foregoing
SUBCLAUSES (A) and (B) as a maximum ceiling on Revolving Credit Loan B;
PROVIDED, HOWEVER, that it is agreed that should Revolving Credit Loan B exceed
the ceiling so determined or any other limitation set forth in this Agreement,
such Revolving Credit Loan B shall nevertheless constitute Secured Obligations
and, as such, shall be entitled to all benefits thereof and security therefor.
The principal amount of any Revolving Credit Loan B which is repaid may be
reborrowed by the Borrower in accordance with the terms of this SECTION 2A.1(b).
The Lender is hereby authorized to record each repayment of principal of
Revolving Credit Loan B in its books and records, such books and records
constituting PRIMA FACIE evidence of the accuracy of the information contained
therein. All Revolving Credit Loans made pursuant to this SECTION 2A.1(b) are
collectively referred to as "REVOLVING CREDIT LOAN B."

<PAGE>

            its intention to borrow, specifying the effective date and amount of
            such proposed Revolving Credit Loan;

                        (ii) whenever a check is presented to the Lender for
            payment against the Disbursement Account in an amount greater than
            the then available balance in such account, such presentation shall
            be deemed to be a request for an advance on Revolving Credit Loan B
            on the date of such notice in an amount equal to the excess of such
            check over such available balance, and such request shall be
            irrevocable;

                        (iii) unless payment is otherwise made by the Borrower,
            the becoming due of any amount required to be paid under this
            Agreement or any of the Notes as interest shall be deemed to be a
            request for an advance on Revolving Credit Loan B on the due date in
            the amount required to pay such interest, and such request shall be
            irrevocable; and

                        (iv) unless payment is otherwise made by the Borrower,
            the maturity of any Secured Obligation required to be paid shall be
            deemed to be a request for an advance on Revolving Credit Loan B on
            the due date in the amount required to pay such Secured Obligation,
            and such request shall be irrevocable.

                  (b) NOTICE OF BORROWING. Any request for an advance on
      Revolving Credit Loan B under SECTION 2A.3(a)(i) (a "NOTICE OF Borrowing")
      shall be made by telephone or in writing (including telecopy) and, in the
      case of any telephonic notice, shall be immediately followed by a written
      confirmation thereof in a form acceptable to the Lender, PROVIDED that the
      failure to provide written confirmation shall not invalidate any
      telephonic notice and, if such written confirmation differs in any respect
      from the action taken by the Lender, the records of the Lender shall
      control absent manifest error.

                  (c) DISBURSEMENT OF LOANS. The Borrower hereby irrevocably
      authorizes the Lender to disburse the proceeds of each borrowing
      requested, or deemed to be requested, pursuant to this SECTION 2A.3 as
      follows: (i) the proceeds of each borrowing requested under SECTION
      2A.3(a)(i) or SECTION 2A.3(a)(ii) shall be disbursed by the Lender in
      lawful money of the United States of America in immediately available
      funds, (A) in the case of the initial borrowing, in accordance with the
      terms of the written instructions from the Borrower to the Lender, and (B)
      in the case of each subsequent borrowing, by credit to the Disbursement
      Account or to such other account as may be agreed upon by the Borrower and
      the Lender from time to time; and (ii) the proceeds of each borrowing
      requested under SECTION 2A.3(a)(iii) OR SECTION 2A.3(a)(iv) shall be
      disbursed by the Lender by way of direct payment of the relevant
      principal, interest or other Secured Obligation, as the case may be.

            The Revolving Credit Loans will be repaid as follows: (a) whether or
not any Default or Event of Default has occurred, the outstanding principal

<PAGE>

accrued and unpaid interest on the amount repaid to the date of repayment, on
the Termination Date; (b) if at any time the aggregate unpaid principal amount

advanced to Borrower pursuant to the Available Commitment (as defined in the
EXIMBANK Documents, with respect to Revolving Credit Loan A) and SECTION 2A.1(b)
hereof (with respect to Revolving Credit Loan B), the Borrower shall repay such
Revolving Credit Loans (or Revolving Credit Loan A or B, as the case may be) in
an amount sufficient to reduce the aggregate unpaid principal amount of such
Loans by an amount equal to such excess, together with accrued and unpaid
interest on the amount repaid to the date of repayment; and (c) the Borrower
hereby instructs the Lender to repay the Revolving Credit Loans outstanding on
any day in an amount equal to the amount received by the Lender on such day
pursuant to SECTION 7.1(b).

            Section 2A.5      REVOLVING CREDIT NOTES.

            The Revolving Credit Loans and the obligation of the Borrower to
repay such Loans shall also be evidenced by Revolving Credit Note A and

                          C. LETTER OF CREDIT FACILITY

            Section 2C.1      LETTERS OF CREDIT.

            (a) Subject to the terms and conditions of this Agreement, and the
Loan Documents, during the term of this Agreement, Lender will, absent the
existence of a Default or Event of Default, from time to time cause the issuance
of, upon Borrower's request, Letters of Credit; PROVIDED, that the Letters of
Credit will be in form and substance acceptable to Lender in its sole
discretion; and PROVIDED FURTHER, that no Letter of Credit will have an
expiration date (i) more than eighteen (18) months from the date of issuance or
(ii) beyond six (6) months after the Termination Date. Borrower's reimbursement
obligation in respect of the Letters of Credit will automatically reduce, dollar
for dollar, the Revolving Credit Loan B Borrowing Base. Any payment made by
Lender to any Person on account of any Letter of Credit will constitute a
Revolving Credit Loan hereunder, to be applied against Revolving Credit Loan B.
At no time will the aggregate sum of direct Revolving Credit Loans by Lender to
Borrower PLUS the outstanding Letter of Credit Obligations exceed the lesser of
the Revolving Credit Facility or the Borrowing Base.

            (b) The Lender will cause to remain in place, the Bond Letter of
Credit, more particularly described as Letter of Credit No. 972771, dated
September 15, 1998 in favor of UMB Bank, as trustee in the amount of
$2,599,572.60. Any payment made by Lender to any Person on account of the Bond
Letter of Credit, including without limitation the monthly interest draws will
charged against ASI's operating account (Bank of America Account #332200008673)
(the "OPERATING ACCOUNT") to the extent of sufficient funds therein. Any payment
made by Lender to any Person on account of the Bond Letter of Credit will
constitute a Revolving Credit Loan hereunder, to be applied against Revolving
Credit Loan B. Except as otherwise provided herein, the Letter of Credit and
Reimbursement Agreement dated as of September 1, 1998 by and among Lender, KHC
of Lenexa, LLC and DCI, Inc. ("REIMBURSEMENT AGREEMENT") will remain in full
force and effect. Notwithstanding the above, the Borrower agrees to execute any
amendment to or modification of the Reimbursement Agreement reasonably required
by the Lender in order to conform the terms of the Reimbursement Agreement to
the terms of this Agreement.


                       ARTICLE 3 - GENERAL LOAN PROVISIONS

            Section 3.1 INTEREST.

            (a) (i) REVOLVING CREDIT LOANS. The Borrower will pay interest on
      the unpaid principal amount of each Revolving Credit Loan for each day
      from the day such Loan was made until such Loan is paid (whether at
      maturity, by reason of acceleration or otherwise), at a rate per annum
      equal to the Prime Rate PLUS one-half of one percent (0.5%), payable
      monthly in arrears on each Interest Payment Date and on the Termination
      Date.

                                      -25-
<PAGE>

                  (ii) TERM LOANS. The Borrower will pay interest on each Term
      Loan at a rate per annum equal to the Prime Rate PLUS one-half of
      one-percent (0.5%) payable in arrears on each Interest Payment Date and
      when such Term Loans are due (whether at maturity, by reason of
      acceleration or otherwise).

            (b) The Borrower shall pay interest on the unpaid principal amount
of each Secured Obligation other than a Loan for each day from the day such
Secured Obligation becomes due and payable until such Secured Obligation is paid
at the rate per annum applicable to Revolving Credit Loans, payable on demand.

            (c) From and after the occurrence of an Event of Default, the unpaid
principal amount of each Secured Obligation shall bear interest until paid in
full (or, if earlier, until such Event of Default is cured or waived in writing
by the Lender) at a rate per annum equal to the Default Margin plus the rate
otherwise in effect under SECTION 3.1(a) or (b), payable on demand. The interest
rate provided for in this SECTION 3.1(c) shall to the extent permitted by
applicable law apply to and accrue on the amount of any judgment entered with
respect to any Secured Obligation and shall continue to accrue at such rate
during any proceeding described in SECTION 11.1(g) or (h).

            (d) The interest rates provided for in SECTIONS 3.1(a), (b) and (c)
shall be computed on the basis of a year of 360 days and the actual number of
days elapsed.

            (e) It is not intended by the Lender, and nothing contained in this
Agreement or any Note shall be deemed, to establish or require the payment of a
rate of interest in excess of the maximum rate permitted by applicable law (the
"MAXIMUM RATE"). If, in any month, the Effective Interest Rate, absent such
limitation, would have exceeded the Maximum Rate, then the Effective Interest
Rate for that month shall be the Maximum Rate, and if, in future months, the
Effective Interest Rate would otherwise be less than the Maximum Rate, then the
Effective Interest Rate shall remain at the Maximum Rate until such time as the
amount of interest paid hereunder equals the amount of interest which would have
been paid if the same had not been limited by the Maximum Rate. In this
connection, in the event that, upon payment in full of the Secured Obligations,
the total amount of interest paid or accrued under the terms of this Agreement
is less than the total amount of interest which would have been paid or accrued
if the Effective Interest Rate had at all times been in effect, then the
Borrower shall, to the extent permitted by applicable law, pay to the Lender an
amount equal to the difference between (i) the lesser of (A) the amount of
interest which would have been charged if the Maximum Rate had, at all times,
been in effect and (B) the amount of interest which would have accrued had the
Effective Interest Rate, at all times, been in effect, and (ii) the amount of
interest actually paid or accrued under this Agreement. In the event the Lender
receives, collects or applies as interest any sum in excess of the Maximum Rate,
such excess amount shall be applied to the reduction of the principal balance of
the applicable Secured Obligation, and, if no such principal is then
outstanding, such excess or part thereof remaining shall be paid to the
Borrower.

            Section 3.2 FEES.

            (a) UNUSED LINE FEE. In connection with and as consideration for the
Lender's commitment hereunder, subject to the terms hereof, to lend to the
Borrower under the


                                      -26-
<PAGE>

Revolving Credit Facility, the Borrower shall pay a fee to the Lender, from the
Effective Date until the Termination Date, in an amount equal to one quarter of
one percent (.25%) per annum of the average daily unused portion of the
Revolving Credit Facility, payable quarterly in arrears on the first day of each
quarter and on the date of any permanent reduction in the Revolving Credit
Facility.

            (b)   COMMITMENT FEE.  Borrower will pay Lender a commitment fee
of $45,000 at closing, which shall be deemed fully earned upon execution of
this Agreement by Borrower and Lender.

            (c)   EXIMBANK FEES.  Borrower will pay certain fees as described
in the EXIMBANK Financing Documents.

            (d) FIELD EXAM FEES. Borrower will pay all of the reasonable
examination fees, costs and expenses incurred by Lender in connection with
periodic field examinations of Borrower's business operation and financial
records and Collateral. Unless a Default or Event of Default has occurred,
Lender will conduct field examinations no more frequently than once every six
(6) months.


            (e)   LETTER OF CREDIT FEES.

                  (1) With respect to all Letters of Credit except the Bond
Letter of Credit, Borrower will pay to Lender, upon issuance of such Letter of
Credit, a Letter of Credit fee equal to the maximum face duration of the Letter
of Credit in years (provided, however, that the minimum deemed face duration of
any Letter of Credit shall be 1/12th of one year) MULTIPLIED BY one and
one-quarter percent (1.25%) of the maximum obligation of the Lender under the
Letter of Credit;

                  (2) With respect to the Bond Letter of Credit, Borrower will
pay to Lender, upon issuance of the Bond Letter of Credit and annually upon each
anniversary of the issuance of the Bond Letter of Credit (prorated in the event
the Bond Letter of Credit is to expire prior to the next such anniversary), a
Letter of Credit fee equal to one and one-quarter percent (1.25%) of the maximum
obligation of the Lender under the Bond Letter of Credit;

            (f) GENERAL. All fees shall be fully earned by the Lender when due
and payable and, except as otherwise set forth herein, shall not be subject to
refund or rebate. All fees are for compensation for services and are not, and
shall not be deemed to be, interest or a charge for the use of money.

            Section 3.3 INCREASED COSTS AND REDUCED RETURNS.

            The Borrower agrees that if any law now or hereafter in effect and
whether or not presently applicable to the Lender or any guideline or directive
of any Governmental Authority (whether or not having the force of law and
whether or not failure to comply therewith would be unlawful) or the
interpretation or administration thereof by any Governmental Authority, shall
either (a)(i) impose, affect, modify or deem applicable any reserve, special
deposit, capital



                                      -27-
<PAGE>

maintenance or similar requirement against any Loan, (ii) impose on the Lender
any other condition regarding any Loan, this Agreement, the Notes or the
facilities provided hereunder, or (iii) result in any requirement regarding
capital adequacy (including any risk-based capital guidelines) affecting the
Lender being imposed or modified or deemed applicable to the Lender, or (b)
subject the Lender to any taxes on the recording, registration, notarization or
other formalization of the Loans or the Notes, and the result of any event
referred to in CLAUSE (A) or (B) above shall be to increase the cost to the
Lender of making, funding or maintaining any Loan or to reduce the amount of any
sum receivable by the Lender or the Lender's rate of return on capital with
respect to any Loan to a level below that which the Lender could have achieved
but for such imposition, modification or deemed applicability (taking into
consideration the Lender's policies with respect to capital adequacy) by an
amount deemed by Lender (in the exercise of its discretion) to be material,
then, upon demand by the Lender, the Borrower shall immediately pay to the
Lender additional amounts which shall be sufficient to compensate the Lender for
such increased cost, tax or reduced rate of return. A certificate of the Lender
to the Borrower claiming compensation under this SECTION 3.3 shall be final,
conclusive and binding on all parties for all purposes in the absence of
manifest error. Such certificate shall set forth the nature of the occurrence
giving rise to such compensation, the additional amount or amounts to be paid to
it hereunder, and the method by which such amounts were determined. In
determining such amount, the Lender may use any reasonable averaging and
attribution methods.

            Section 3.4 MANNER OF PAYMENT.

            (a) Each payment (including prepayments) by the Borrower on account
of the principal of or interest on the Loans or of any fee or other amounts
payable to the Lender under this Agreement or any Note shall be made not later
than 1:30 p.m. on the date specified for payment under this Agreement (or if
such day is not a Business Day, the next succeeding Business Day) to the Lender
at the Lender's Office, in Dollars, in immediately available funds and shall be
made without any setoff, counterclaim or deduction whatsoever.

            (b) The Borrower hereby irrevocably authorizes the Lender and each
Affiliate of the Lender to charge any account of the Borrower maintained with
the Lender or such Affiliate with such amounts as may be necessary from time to
time to pay any Secured Obligations which are not paid when due.

            Section 3.5 TERMINATION OF AGREEMENT.

            (a) On the Termination Date, the Borrower shall pay to the Lender,
in same day funds, an amount equal to the aggregate amount of all Loans
outstanding on such date, together with accrued interest thereon, all fees
payable pursuant to SECTION 3.2 accrued from the date last paid through the
effective date of termination, any amounts payable to the Lender pursuant to the
other provisions of this Agreement, including, without limitation, SECTIONS 3.3,
11.2, 12.12 and 12.13, any and all other Secured Obligations then outstanding
and provide the Lender with an indemnification agreement in form and substance
satisfactory to the Lender with respect to returned and dishonored items and
such other matters as the Lender shall require. Borrower may terminate this
Agreement at any time prior to the Termination Date by paying all of the
outstanding Loans in full together with all interest, fees, costs and other
expenses required hereunder and terminating all Letters of Credit, plus a
prepayment fee of (a) two percent (2%) of



                                      -28-
<PAGE>

the Maximum Credit Facility if such termination occurs on or before the last day
of the eighteenth (18th) month after the Effective Date hereof; or (b) one
percent (1%) of the Maximum Credit Facility if the Termination Date has been
extended and such termination occurs before the new Termination Date but after
the eighteenth month after the Effective Date hereof ("PREPAYMENT FEE").

            (b) Provided that no Default or Event of Default has occurred and is
continuing or would occur as a result, upon the written request of the Borrower,
Lender will permit Borrower to permanently reduce Term Loan A, Term Loan B
and/or Revolving Credit Loan B ("PERMANENT REDUCTIONS") on the following
conditions: (i) all Permanent Reductions shall be in increments of not less than
Two Hundred Thousand and No/100 Dollars ($200,000.00); (ii) Permanent Reductions
shall not occur more than once in any thirty (30) day period; (iii) Permanent
Reductions shall not occur more than four (4) times during the course of the
Loan; (iv) Lender shall be under no obligation to re-lend any amount permanently
reduced pursuant to a Permanent Reduction; (v) a Permanent Reduction may not be
made which would cause an overadvance against the Revolving Credit Loan B
Borrowing Base after giving effect to such Permanent Reduction; (vi) a Permanent
Reduction will be evidenced by an amendment to this Agreement, and will not be
effective until acknowledged by Lender to Borrower in writing; (vii) a Permanent
Reduction would be supported by an equity investment into ASI in an amount

Permanent Reduction Prepayment Fee (as hereinafter defined) to Lender; and (ix)

one-third percent (1.33%) of the amount of the Permanent Reduction if such
termination occurs on or before the last day of the eighteenth (18th) month
after the Effective Date hereof; or (b) two-thirds of one percent (.67%) of the
amount of the Permanent Reduction if the Termination Date has been extended and
such termination occurs before the new Termination Date but after the eighteenth
month after the Effective Date hereof.

returns and credits in excess of $50,000 in respect of any Receivable, which
notice shall specify the Receivables affected.

to a Default or an Event of Default, grant any extension of time for payment of
any Receivable or compromise, compound or settle the same for less than the full
amount thereof or release wholly or partly any Person liable for the payment
thereof or allow any credit or discount whatsoever thereon (an "ADJUSTMENT");
PROVIDED that (i) no Adjustment results in the reduction of more than $75,000 in

customers or is otherwise recovered.

Collateral or any interest therein, except for sales of Inventory in the
ordinary course of business, for cash or on open account or on terms of payment
ordinarily extended to its customers and except as otherwise expressly
contemplated herein. The inclusion of "proceeds" of the Collateral under the
Security Interest shall not be deemed a consent by the Lender to any other sale
or other disposition of any part or all of the Collateral. Notwithstanding the
above, Borrower may sell, transfer, convey or otherwise dispose of worn out or
obsolete equipment up to an aggregate market value of $10,000 during the term of

sale, transfer, conveyance or disposition will be applied to the Secured
Obligations in the order determined by Lender in its sole but reasonable
discretion. Any other such dispositions shall be made only with the prior
written consent of the Lender, which consent shall not be unreasonably withheld,
provided that, Lender may, in its sole discretion, require the proceeds of such
disposition to be applied to the Secured Obligations in the order determined by
Lender or to the purchase of replacement Equipment in which the Lender will have
the first perfected security interest.

            (b) The Borrower shall defend its title in and to the Collateral and
shall defend the Security Interest in the Collateral against the claims and
demands of all Persons.

            (c) In addition to, and not in derogation of, the foregoing and the
requirements of any of the Security Documents, the Borrower shall (i) protect
and preserve all properties material to its business, including Intellectual
Property and maintain all tangible property in good and workable condition in
all material respects, with reasonable allowance for wear and tear, and (ii)
from time to time make or cause to be made all needed and appropriate repairs,
renewals, replacements and additions to such properties necessary for the
conduct of its business, so that the business carried on in connection therewith

are paid to the Lender which, in the aggregate with respect to any particular
incident, event or claim are:

contained in, or the payment of any other sum covenanted to be paid by any
Obligor under, any such Loan Document; or any provision of this Agreement, or of
any other Loan Document after delivery thereof hereunder, shall for any reason
cease to be valid and binding, other than a nonmaterial provision rendered
unenforceable by operation of law, or any Obligor or other party thereto (other
than the Lender) shall so state in writing; or this Agreement or any other Loan
Document, after delivery thereof hereunder, shall for any reason (other than any
action taken independently by the Lender and except to the extent permitted by
the terms thereof) cease to create a valid, perfected and, except as otherwise
expressly permitted herein, first priority Lien on, or security interest in, any
of the Collateral purported to be covered thereby.

            (j) JUDGMENT. A judgment or order for the payment of money which
exceeds $50,000 in amount shall be entered against any Obligor by any court and

market value of the assets of any other Benefit Plan with respect to which a
Termination Event occurs on the same day (but only to the extent that such
excess is the property of the Borrower) over (B) the present value on such day
of all vested nonforfeitable benefits under such other Benefit Plan, results in
an Unfunded Vested Accrued Benefit in excess of $0, (ii) any Benefit Plan shall
incur an "accumulated funding deficiency" (as defined in Section 412 of the Code
or Section 302 of ERISA) for which a waiver has not been obtained in accordance
with the applicable provisions of the Code and ERISA, or (iii) the Borrower is
in "default" (as defined in Section 4219(c)(5) of ERISA) with respect to

            (o) MATERIAL ADVERSE CHANGE. There occurs any act, omission, event,
undertaking or circumstance or series of acts, omissions, events, undertakings

of the Loan Documents to the contrary notwithstanding, and (ii) the Revolving
Credit Facility and the commitment of the Lender to make advances thereunder or
under this Agreement shall immediately terminate.

            (b)   OTHER REMEDIES.  If any Event of Default (other than as
specified in SECTION 11.1(g) or (h)) shall have occurred and be continuing,
the Lender, in its sole and absolute discretion, may do any of the following:

      Notes at the time outstanding, and all other amounts owed to the Lender
      under this Agreement or any of the Loan Documents and all other Secured
      Obligations, to be forthwith due and payable, whereupon the same shall

      this Agreement or the Loan Documents to the contrary notwithstanding;

                  (ii)  terminate the Revolving Credit Facility and any

      otherwise, any Account Debtor or obligor with respect to any one or more
      of the Receivables to make payment to the Lender or any agent or designee
      of the Lender, at such address as may be specified by the Lender, and, if,
      notwithstanding the giving of any notice, any Account Debtor or other such
      obligor shall make payments to the Borrower, the Borrower shall hold all
      such payments it receives in trust for the Lender, without commingling the
      same with other funds or property of, or held by, the Borrower and shall
      deliver the same to the Lender or any such agent or designee immediately
      upon receipt by the Borrower in the identical form received, together with
      any necessary endorsements;

                  (ii) settle or adjust disputes and claims directly with
      Account Debtors and other obligors on Receivables for amounts and on terms

                                      -58-
<PAGE>

      advisable and in all such cases only the net amounts received by the
      Lender in payment of such amounts, after deductions of costs and
      attorneys' fees, shall constitute Collateral, and the Borrower shall have
      no further right to make any such settlements or adjustments or to accept
      any returns of merchandise;

                  (iii) enter upon any premises on which Inventory or Equipment
      may be located and, without resistance or interference by the Borrower,
      take physical possession of any or all thereof and maintain such
      possession on such premises or move the same or any part thereof to such
      other place or places as the Lender shall choose, without being liable to
      the Borrower on account of any loss, damage or depreciation that may occur
      as a result thereof, so long as the Lender shall act reasonably and in
      good faith;

                  (iv) require the Borrower to and the Borrower shall, without
      charge to the Lender, assemble the Inventory and Equipment and maintain or

      representative of the Lender at such place or places as the Lender may
      designate;

                  (v) at the expense of the Borrower, cause any of the Inventory
      and Equipment to be placed in a public or field warehouse, and the Lender
      shall not be liable to the Borrower on account of any loss, damage or
      depreciation that may occur as a result thereof, so long as the Lender
      shall act reasonably and in good faith;

                  (vi) without notice, demand or other process, and without
      payment of any rent or any other charge, enter any of the Borrower's
      premises and, without breach of the peace, until the Lender completes the
      enforcement of its rights in the Collateral, take possession of such
      premises or place custodians in exclusive control thereof, remain on such
      premises and use the same and any of the Borrower's equipment, for the
      purpose of (A) completing any work in process, preparing any Inventory for
      disposition and disposing thereof, and (B) collecting any Receivable, and
      the Lender is hereby granted a license or sublicense and all other rights
      as may be necessary, appropriate or desirable to use the Intellectual
      Property in connection with the foregoing, and the rights of the Borrower
      under all licenses and franchise agreements shall inure to the Lender's
      benefit (provided, however, that any use of any federally registered
      trademarks as to any goods shall be subject to the control as to the
      quality of such goods of the owner of such trademarks and the goodwill of
      the business symbolized thereby);

                  (vii) exercise any and all of its rights under any and all
      of the Security Documents;

                  (viii) apply any cash Collateral to the payment of the Secured
      Obligations in any order in which the Lender may elect or use such cash in

                  (ix) establish or cause to be established one or more

                                      -59-
<PAGE>

      shall cause to be forwarded to the Lender at the Lender's Office, on a
      daily basis, copies of all checks and other items of payment and deposit
      slips related thereto deposited in such lockboxes, together with
      collection reports in form and substance satisfactory to the Lender; and

                  (x) exercise all of the rights and remedies of a secured party
      under the UCC (whether or not the UCC is applicable) and under any other
      applicable law, including, without limitation, the right, without notice
      except as specified below and with or without taking the possession
      thereof, to sell the Collateral or any part thereof in one or more parcels
      at public or private sale, at any location chosen by the Lender, for cash,
      on credit or for future delivery and at such price or prices and upon such
      other terms as the Lender may deem commercially reasonable. The Borrower
      agrees that, to the extent notice of sale shall be required by law, at
      least 10 days' notice (or such longer period as required by law) to the
      Borrower of the time and place of any public sale or the time after which
      any private sale is to be made shall constitute reasonable notice, but
      notice given in any other reasonable manner or at any other reasonable
      time shall also constitute reasonable notification. The Lender shall not
      be obligated to make any sale of Collateral regardless of notice of sale
      having been given. The Lender may adjourn any public or private sale from
      time to time by announcement at the time and place fixed therefor, and
      such sale may, without further notice, be made at the time and place to
      which it was so adjourned.

            Section 11.3      Application of Proceeds.

            All proceeds from each sale of, or other realization upon, all or
any part of the Collateral following an Event of Default shall be applied or
paid over as follows:

            (a)   FIRST:  to the payment of all costs and expenses incurred
in connection with such sale or other realization, including reasonable
attorneys' fees,

            (b)   SECOND:  to the payment of the Secured Obligations (with
the Borrower remaining liable for any deficiency) in any order which the
Lender may elect, and

            (c)   THIRD:  the balance (if any) of such proceeds shall be paid
to the Borrower or, subject to any duty imposed by law or otherwise, to
whomsoever is entitled thereto.

THE BORROWER SHALL REMAIN LIABLE AND WILL PAY, ON DEMAND, ANY DEFICIENCY
REMAINING IN RESPECT OF THE SECURED OBLIGATIONS, TOGETHER WITH INTEREST THEREON
AT A RATE PER ANNUM EQUAL TO THE HIGHEST RATE THEN PAYABLE HEREUNDER ON SUCH
SECURED OBLIGATIONS, WHICH INTEREST SHALL CONSTITUTE PART OF THE SECURED
OBLIGATIONS.

            Section 11.4      Power of Attorney.

            In addition to the authorizations granted to the Lender under
SECTION 7.15 or under any other provision of this Agreement or any of the Loan
Documents, upon and after an Event of Default, the Borrower hereby irrevocably
designates, makes, constitutes and appoints the Lender (and all Persons
designated by the Lender from time to time) as the Borrower's true


                                      -60-

may, without notice to the Borrower, and at such time or times as the Lender or

or the Lender,

            (a) demand payment of the Receivables, enforce payment thereof by
legal proceedings or otherwise, settle, adjust, compromise, extend or renew any
or all of the Receivables or any legal proceedings brought to collect the
Receivables, discharge and release the Receivables or any of them and exercise
all of the Borrower's rights and remedies with respect to the collection of
Receivables,

            (b) prepare, file and sign the name of the Borrower on any proof of
claim in bankruptcy or any similar document against any Account Debtor or any
notice of Lien, assignment or satisfaction of Lien or similar document in
connection with any of the Collateral,

            (c) endorse the name of the Borrower upon any chattel paper,
document, instrument, notice, freight bill, bill of lading or similar document
or agreement relating to the Receivables, the Inventory or any other Collateral,

            (d) use the stationery of the Borrower, open the Borrower's mail,
notify the post office authorities to change the address for delivery of the
Borrower's mail to an address designated by the Lender and sign the name of the
Borrower to verifications of the Receivables and on any notice to the Account
Debtors,

            (e) use the information recorded on or contained in any data
processing equipment and computer hardware and software relating to the

            (a) RIGHTS CUMULATIVE. The rights and remedies of the Lender under
this Agreement, the Note and each of the Loan Documents shall be cumulative and
not exclusive of any rights or remedies which it or they would otherwise have.
In exercising such rights and remedies, the Lender may be selective and no
failure or delay by the Lender in exercising any right shall operate as a waiver
of such right nor shall any single or partial exercise of any power or right
preclude its other or further exercise or the exercise of any other power or
right.

            (b)   WAIVER OF MARSHALING.  The Borrower hereby waives any right
to require any marshaling of assets and any similar right.

            (c) LIMITATION OF LIABILITY. Nothing contained in this ARTICLE 11 or
elsewhere in this Agreement or in any of the Loan Documents shall be construed
as requiring or obligating the Lender or any agent or designee of the Lender to
make any demand or to make any inquiry as to the nature or sufficiency of any
payment received by it or to present or file any claim or notice or take any
action with respect to any Receivable or any other Collateral or the moneys due
or to become due thereunder or in connection therewith or to take any steps
necessary to preserve any rights against prior parties, and neither the Lender
nor any of its agents or designees shall have any liability to the Borrower for
actions taken pursuant to this Article 11, any other provision of


                                      -61-

this Agreement or any of the Loan Documents, so long as the Lender or such agent
or designee shall act reasonably and in good faith.

            (d) APPOINTMENT OF RECEIVER. In any action under this ARTICLE 11,
the Lender shall be entitled to the appointment of a receiver, without notice of
any kind whatsoever, to take possession of all or any portion of the Collateral

            The Borrower hereby grants to the Lender the nonexclusive right and
license to use any trademarks, tradenames and servicemarks then used by the
Borrower, for the purposes set forth in SECTION 11.2(c)(vi) and for the purpose
of enabling the Lender to realize on the Collateral and to permit any purchaser
of any portion of the Collateral through a foreclosure sale or any other
exercise of the Lender's rights and remedies under the Loan Documents to use,
sell or otherwise dispose of the Collateral bearing any such trademark. Such
right and license is granted free of charge, without the requirement that any
monetary payment whatsoever be made to the Borrower or any other Person by the
Lender. The Borrower hereby represents, warrants, covenants and agrees that it
presently has, and shall continue to have, the right, without the approval or
consent of others, to grant the license set forth in this SECTION 11.6.

            Section 11.7 FORBEARANCE/MODIFICATION FEES. If Borrower requests,
and Lender agrees, in Lender's sole and absolute discretion, to enter into a
forbearance or modification agreement in connection with any Default, Event of
Default or potential default, in addition to legal and other fees, costs and
expenses incurred in connection with Lender's protection of its Collateral, due
diligence and documentation, Borrower will pay a forbearance or modification fee

NATURE IN ANY COURT IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST THE
BORROWER OR THE LENDER ARISING OUT OF THIS AGREEMENT, THE COLLATERAL OR ANY

THE BORROWER AND THE LENDER OF ANY KIND OR NATURE. THE BORROWER AND THE LENDER
HEREBY AGREE THAT THE FEDERAL COURT OF THE WESTERN DISTRICT OF MISSOURI OR, AT
THE OPTION OF THE LENDER, ANY COURT IN WHICH THE LENDER SHALL INITIATE LEGAL OR
EQUITABLE PROCEEDINGS AND WHICH HAS SUBJECT MATTER JURISDICTION OVER THE MATTER
IN CONTROVERSY AND WHICH SITS IN A JURISDICTION IN WHICH THE BORROWER TRANSACTS
BUSINESS SHALL HAVE NON-EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS
OR DISPUTES BETWEEN THE BORROWER AND THE LENDER, PERTAINING DIRECTLY OR
INDIRECTLY TO THIS AGREEMENT OR THE LOAN DOCUMENTS OR TO ANY MATTER ARISING
THEREFROM. THE BORROWER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS, HEREBY
WAIVING PERSONAL SERVICE OF THE SUMMONS AND COMPLAINT OR OTHER PROCESS OR PAPERS
ISSUED THEREIN AND AGREEING THAT SERVICE OF SUCH SUMMONS AND COMPLAINT OR OTHER
PROCESS OR PAPERS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO THE
BORROWER AT THE ADDRESS SET FORTH IN SECTION 12.1(B), WHICH SERVICE SHALL BE
DEEMED MADE UPON RECEIPT THEREOF. THE NON-EXCLUSIVE CHOICE OF FORUM SET FORTH IN
THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE ENFORCEMENT OF ANY JUDGMENT
OBTAINED IN SUCH FORUM OR THE TAKING OF ANY ACTION UNDER THIS AGREEMENT TO
ENFORCE THE SAME IN ANY APPROPRIATE JURISDICTION. NOTWITHSTANDING ING TO THE
CONTRARY CONTAINED HEREIN, EXCEPTING THE LIMITED PROVISIONS OF SECTION 7.9(C)
HEREOF, NOTHING CONTAINED IN THIS AGREEMENT SHALL BE CONSTRUED AS LENDER'S
CONSENT TO SUBMIT ANY DISPUTES, DISAGREEMENTS OR OTHER ISSUES OF ANY KIND
WHATSOEVER UNDER THIS AGREEMENT OR ANY OF THE LOAN DOCUMENTS TO ARBITRATION,
MEDIATION OR ANY OTHER FORM OF ALTERNATIVE DISPUTE RESOLUTION.

            Section 12.6      WAIVER OF RIGHTS.

            THE BORROWER HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY WAIVES
ALL RIGHTS WHICH THE BORROWER HAS UNDER APPLICABLE LAW TO NOTICE AND TO A
JUDICIAL HEARING PRIOR TO THE ISSUANCE OF A WRIT OF POSSESSION ENTITLING THE
LENDER, ITS SUCCESSORS AND ASSIGNS TO POSSESSION OF THE COLLATERAL UPON DEFAULT
OR EVENT OF DEFAULT. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING AND

                                      -65-
<PAGE>

WITHOUT LIMITING ANY OTHER RIGHT WHICH THE LENDER MAY HAVE, THE BORROWER
CONSENTS THAT, IF THE LENDER FILES A PETITION FOR AN IMMEDIATE WRIT OF
POSSESSION UNDER APPLICABLE LAW AND THIS WAIVER OR A COPY HEREOF IS ALLEGED IN
SUCH PETITION AND ATTACHED THERETO, THE COURT BEFORE WHICH SUCH PETITION IS
FILED MAY DISPENSE WITH ALL RIGHTS AND PROCEDURES HEREIN WAIVED AND MAY ISSUE
FORTHWITH AN IMMEDIATE WRIT OF POSSESSION IN ACCORDANCE WITH APPLICABLE LAW,
WITHOUT THE NECESSITY OF AN ACCOMPANYING BOND AS OTHERWISE MAY BE REQUIRED BY
APPLICABLE LAW. THE BORROWER HEREBY ACKNOWLEDGES THAT IT HAS READ AND FULLY
UNDERSTANDS THE TERMS OF THIS WAIVER AND THE EFFECT HEREOF.

            Section 12.7      REVERSAL OF PAYMENTS.

            To the extent the Borrower makes a payment or payments to the Lender
or the Lender receives any payment or proceeds of the Collateral for the
Borrower's benefit, which payment(s) or proceeds or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then, the
Lender shall have the continuing and exclusive right to apply, reverse and
re-apply any and all payments to any portion of the Secured Obligations, and, to
the extent of such payment or proceeds received, the Secured Obligations or part
thereof intended to be satisfied shall be revived and continued in full force
and effect, as if such payment or proceeds had not been received by the Lender.

            Section 12.8      INJUNCTIVE RELIEF.

            The Borrower recognizes that, in the event the Borrower fails to
perform, observe or discharge any of its obligations or liabilities under this
Agreement, any remedy of law may prove to be inadequate relief to the Lender;
therefore, the Borrower agrees that the Lender, at the Lender's option, shall be
entitled to temporary and permanent injunctive relief in any such case without
the necessity of proving actual damages.

            Section 12.9      ACCOUNTING MATTERS.

            All financial and accounting calculations, measurements and
computations made for any purpose relating to this Agreement, including, without
limitation, all computations utilized by the Borrower to determine whether it is
in compliance with any covenant contained herein, shall, unless there is an
express written direction or consent by the Lender to the contrary, be performed
in accordance with GAAP.

            Section 12.10     ASSIGNMENT; PARTICIPATION.

            All the provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
under this Agreement. The Lender may assign to one or more Persons, or sell
participations to one or more Persons in, all or a portion of its rights and

                                      -66-
<PAGE>

obligations hereunder and under the Note and, in connection with any such
assignment or sale of a participation, may assign its rights and obligations
under the Security Documents. The Lender may, in connection with any assignment
or proposed assignment or sale or proposed sale of a participation, disclose to
the assignee or proposed assignee or participant or proposed participant any
information relating to the Borrower furnished to the Lender by or on behalf of
the Borrower, provided that such assignee, proposed assignee, participant or
proposed participant agrees to keep such information confidential.

            Section 12.11     AMENDMENTS.

            Any term, covenant, agreement or condition of this Agreement or any
of the other Loan Documents may be amended or waived and any departure therefrom
may be consented to if, but only if, such amendment, waiver or consent is in
writing signed by the Lender and, in the case of an amendment, by the Borrower.
Unless otherwise specified in such waiver or consent, a waiver or consent given
hereunder shall be effective only in the specific instance and for the specific
purpose for which given.

            Section 12.12     PERFORMANCE OF BORROWER'S DUTIES.

            The Borrower's obligations under this Agreement and each of the Loan
Documents shall be performed by the Borrower at its sole cost and expense. If
the Borrower shall fail to do any act or thing which it has covenanted to do
under this Agreement or any of the Loan Documents, the Lender may (but shall not
be obligated to) do the same or cause it to be done either in the name of the
Lender or in the name and on behalf of the Borrower, and the Borrower hereby
irrevocably authorizes the Lender so to act.

            Section 12.13     INDEMNIFICATION.

            The Borrower agrees to reimburse the Lender for all reasonable costs
and expenses, including counsel fees and disbursements, incurred and to
indemnify and hold the Lender harmless from and against all losses suffered by
the Lender, other than losses resulting from the Lender's gross negligence or
willful misconduct, in connection with (a) the exercise by the Lender of any
right or remedy granted to it under this Agreement or any of the Loan Documents,
(b) any claim, and the prosecution or defense thereof, arising out of or in any
way connected with this Agreement or any of the Loan Documents, except in the
case of a dispute between the Borrower and the Lender in which the Borrower
prevails in a final unappealed or unappealable judgment, and (c) the collection
or enforcement of the Secured Obligations or any of them.

            Section 12.14     ALL POWERS COUPLED WITH INTEREST.

            All powers of attorney and other authorizations granted to the
Lender and any Persons designated by the Lender pursuant to any provisions of
this Agreement or any of the Loan Documents shall be deemed coupled with an
interest and shall be irrevocable so long as any of the Secured Obligations
remain unpaid or unsatisfied or the Revolving Credit Facility has not been
terminated.

                                      -67-
<PAGE>

            Section 12.15     SURVIVAL.

            Notwithstanding any termination of this Agreement, (a) until all
Secured Obligations have been paid in full and the Revolving Credit Facility
terminated, the Lender shall retain its Security Interest and shall retain all
rights under this Agreement and each of the Security Documents with respect to
the Collateral as fully as though this Agreement had not been terminated, and
(b) the indemnities to which the Lender is entitled under the provisions of this
Article 12 and any other provision of this Agreement and the Loan Documents
shall continue in full force and effect and shall protect the Lender against
events arising after such termination as well as before.

            Section 12.16     SEVERABILITY OF PROVISIONS.

            Any provision of this Agreement or any other Loan Document which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective only to the extent of such prohibition or unenforceability
without invalidating the remainder of such provision or the remaining provisions
hereof or thereof or affecting the validity or enforceability of such provision
in any other jurisdiction.

            Section 12.17     GOVERNING LAW.

            This Agreement, the Note and all other Loan Documents shall be
construed in accordance with and governed by the law of the State of Missouri
except as expressly provided therein.

            Section 12.18     COUNTERPARTS.

            This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and shall be binding upon all
parties, their successors and assigns, and all of which taken together shall
constitute one and the same agreement.

            Section 12.19     REPRODUCTION OF DOCUMENTS.

            This Agreement, each of the Loan Documents and all documents
relating thereto, including, without limitation, (a) consents, waivers and
modifications that may hereafter be executed, (b) documents received by the
Lender, and (c) financial statements, certificates and other information
previously or hereafter furnished to the Lender, may be reproduced by the Lender
by any photographic, photostatic, microcard, microfilm, miniature photographic
or other similar process, and the Lender may destroy any original document so
reproduced. Each party hereto stipulates that, to the extent permitted by
applicable laws any such reproduction shall be as admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original shall be in existence and whether or not such reproduction was made by
such Lender in the regular course of business), and any enlargement, facsimile
or further reproduction of such reproduction shall likewise be admissible in
evidence.

            Section 12.20      FUNDS TRANSFER SERVICES.

            (a) The Borrower acknowledges that the Lender has made available to
it a description of security procedures regarding funds transfers executed by
the Lender or an affiliate bank at the request of such Borrower (the "Security
Procedures"). The Borrower and the Lender agree that the Security Procedures are
commercially reasonable. The Borrower further acknowledges that the full scope
of the Security Procedures which the Lender or such affiliate bank offers and
strongly recommends for funds transfers is available only if the Borrower
communicates directly with the Lender or such affiliate bank as applicable in
accordance with said procedures. If the Borrower attempts to communicate by any
other method or otherwise not in accordance with the Security Procedures, the
Lender or such affiliate bank, as applicable, shall not be required to execute
such instructions, but if the Lender or such affiliate bank, as applicable, does
so, the Borrower will be deemed to have refused the Security Procedures that the
Lender or such affiliate bank, as applicable, offers and strongly recommends,
and the Borrower will be bound by any funds transfer, whether or not authorized,
which is issued in the Borrower's name and accepted by the Lender or such
affiliate bank, as applicable, in good faith. The Lender or such affiliate bank,
as applicable, may modify the Security Procedures at such time or times and in
such manner as the Lender or such affiliate bank, as applicable, in its sole
discretion, deems appropriate to meet prevailing standards of good banking
practice. By continuing to use the Lender's or such affiliate bank's, as
applicable, wire transfer services after receipt of any modification of the
Security Procedures, the Borrower agrees that the Security Procedures, as
modified, are likewise commercially reasonable. The Borrower further agrees to
establish and maintain procedures to safeguard the Security Procedures and any
information related thereto.

            (b) The Lender or such affiliate bank, as applicable, will generally
use the Fedwire funds transfer system for domestic funds transfers, and the
funds transfer system operated by the Society for Worldwide International
Financial Telecommunication (SWIFT) for international funds transfers.
International funds transfers may also be initiated through the Clearing House
InterBank Payment System (CHIPs) or international cable. However, the Lender or
such affiliate bank, as applicable, may use any means and routes that the Lender
or such affiliate bank, as applicable, in its sole discretion, may consider
suitable for the transmission of funds. Each payment order, or cancellation
thereof, carried out through a funds transfer system or a clearing house will be
governed by all applicable funds transfer system rules and clearing house rules
and clearing arrangements, whether or not the Lender or such affiliate bank, as
applicable, is a member of the system, clearing house or arrangement and the
Borrower acknowledges that the Lender's or such affiliate bank's, as applicable,
right to reverse, adjust, stop payment or delay posting of an executed payment
order is subject to the laws, regulations, rules, circulars and arrangements
described herein.

            Section 12.21     CONSENT TO ADVERTISING AND PUBLICITY.

            The Borrower agrees that the Lender may issue and disseminate to the
public information describing the credit accommodation entered into pursuant to
this Agreement, including the name and address of the Borrower and the amount
and a general description of the credit facilities provided hereunder.

            Section 12.25.  YEAR 2000.

            The Company has (i) initiated a review and assessment of all areas
within its and each of its Subsidiaries' business operations (including those
affected by suppliers, vendors and customers) that could be adversely affected
by the "Year 2000 Problem" (that is, the risk that computer applications used by
the Company or any of its Subsidiaries (or suppliers, vendors and customers) may
be unable to recognize and perform properly dated-sensitive functions involving
certain dates prior to and any date after December 31, 1999), (ii) developed a
plan and timeline for addressing the Year 2000 Problem on a timely basis, and
(iii) to date, implemented that plan in accordance with that timetable. Based on
the foregoing, the Company believes that all computer applications (including
those of its suppliers, vendors and customers) that are material to its or any
of its Subsidiaries' business and operations are reasonably expected on a timely
basis to be able to perform properly date-sensitive functions for all dates
before and after January 1, 2000 (that is, be "Year 2000 compliant"), except to
the extent that a failure to do so could not reasonably be expected to have a
Materially Adverse Effect.

                             REVOLVING CREDIT NOTE B

$3,000,000                                      Date:  February 7, 2000


            FOR VALUE RECEIVED, on February 7, 2000 the undersigned promises to
pay to the order of BANK OF AMERICA, N.A., (hereinafter, together with any
holder hereof, called "HOLDER") at Kansas City, Missouri (or at such other place
as the Holder may designate in writing to the undersigned) the principal amount
of Three Million and No/100 Dollars ($3,000,000.00) or so much thereof as has
been advanced hereunder.

            The undersigned shall pay interest as provided in that certain Loan
and Security Agreement between the undersigned and Holder dated February 7,
2000 (the "LOAN AGREEMENT"). Unless otherwise defined herein, defined terms
shall have the same meaning as in the Loan Agreement.

            It is contemplated that the principal sum evidenced by this Note may
be reduced from time to time and that additional advances may be made from time
to time, as provided in the Loan Agreement; provided, however, that the
outstanding principal amount evidenced by this Note shall not exceed the maximum
amount provided in the Loan Agreement.

            This Note is subject to the terms and conditions of, and entitled to
the benefit of the Collateral described in, the Loan Agreement. Capitalized
terms not defined herein shall have the meanings given in the Loan Agreement.

            No delay or failure on the part of the Holder in the exercise of any
right or remedy hereunder, under the Loan Agreement, the Security Documents or
at law or in equity, shall operate as a waiver thereof, and no single or partial

remedy.

            Principal and interest on this Note shall be payable and paid in
lawful money of the United States of America.

            The undersigned and all endorsers waive presentment, notice of
dishonor and protest.

collected by law or through an attorney at law, or under advice therefrom, the
undersigned agrees to pay all costs of collection, including reasonable
attorneys' fees if collected by or through an attorney.

all rights and obligations of the parties hereunder determined in accordance

            THIS REVOLVING CREDIT NOTE "B" EVIDENCES, IN PART, THE SAME
INDEBTEDNESS AS EVIDENCED BY DOCUMENTATION RELATING TO THE "EXISTING LOANS" (AS
SUCH TERM IS DEFINED IN THE LOAN AGREEMENT). THIS REVOVING CREDIT NOTE "B" IS
SECURED BY ALL OF THE SAME COLLATERAL AS THE EXISTING LOANS PURSUANT TO THE
TERMS OF THE LOAN AGREEMENT AND RELATED LOAN DOCUMENTS. ALL FUTURE ADVANCES MADE
TO THE MAKER WILL ALSO BE SECURED BY THE LOAN DOCUMENTS. THIS REVOLVING NOTE "B"
IS, IN PART, A RESTATEMENT OF THE EXISTING LOANS AND THE DOCUMENTS RELATING
THERETO, AND ITS EXECUTION AND DELIVERY DOES NOT EVIDENCE A CANCELLATION OF THE
INDEBTEDNESS EVIDENCED BY THE PRIOR DOCUMENTS.

            IN WITNESS WHEREOF, the undersigned has caused this Note to be
executed, sealed and delivered in Kansas City, Missouri, in its corporate name,
by and through its respective duly authorized officers, as of the day and year

                          REGISTRATION RIGHTS AGREEMENT


      This  Agreement  is made as of  February 7, 2000,  by and among  Airport
Systems International,  Inc., a Kansas corporation ("ASII"), Chris I. Hammond,
William  D.  Cook and  Larry C.  Klusman  (each of  them,  an  "Investor"  and
collectively, the "Investors").

      WHEREAS, pursuant to that certain Stock Purchase Agreement to be entered
into by and among ASII, DCI, Inc., ("DCI") and the Investors (the "Stock
Purchase Agreement"), ASII shall purchase all of the issued and outstanding
stock of DCI from Investors (the "Acquisition") and the Investors shall receive,
as partial consideration for such stock, common stock of ASII, par value $.01
per share ("ASII Common Stock"), resulting in the issuance of an aggregate of
150,000 shares of ASII Common Stock.

      WHEREAS, pursuant to the terms of the Stock Purchase Agreement, the
Investors shall be granted certain registration rights and ASII shall register
the ASII Common Stock received by the Investors for resale pursuant to the terms
set forth in this Agreement (the "Requested Registration").

      NOW, THEREFORE, in consideration of the mutual covenants, conditions, and
agreements set forth herein and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, it is hereby agreed as
follows:

      Section 1.  Definitions.   The   definitions  set  forth  in  the  Stock
Purchase  Agreement will apply to terms used in this  Agreement.  In addition,
the following terms shall have the following meanings:

            (a) "Exchange Act" means the Securities Exchange Act of 1934, as
      amended, or any similar federal statute and the rules and regulations
      thereunder, all as the same shall be in effect at the time.

            (b) "Register," "registered" and "registration" refers to a
      registration effected by preparing and filing a registration statement in
      compliance with the Securities Act, and the declaration or ordering of the
      effectiveness of such registration statement, and compliance with
      applicable state securities laws of such states in which the Investors
      notify ASII of their intention to offer Registrable Securities.

            (c) "Registrable Securities" means all of the following, to the
      extent the same have not been sold to the public, any and all ASII Common
      Stock issued to the Investors pursuant to the Stock Purchase Agreement, or
      (ii) stock issued in respect of stock referred to in (i) above in any
      reorganization; or (iii) stock issued in respect of the stock referred to
      in (i) or (ii) as a result of a stock split, stock dividend,
      recapitalization or combination. Notwithstanding the foregoing,
      Registrable Securities shall not include otherwise Registrable Securities
      (i) sold to or through a broker in a transaction pursuant to Rule 144 or
      otherwise exempt from the registration and prospectus delivery
      requirements of the Securities Act under Section 4(l) thereof so that all
      transfer restrictions, and restrictive


<PAGE>

      legends with respect thereto, if any, are removed upon the consummation of
      such sale, or (ii) as to which the registration rights have been
      terminated pursuant to this Agreement.

            (d) "Rule 144" means Rule 144 under the Securities Act or any
      successor or similar rule as may be enacted by the SEC from time to time.

            (e) "Securities Act" means the Securities Act of 1933, as amended.

      Section 2.  DEMAND REGISTRATION.

      (a)   DEMAND BY THE INVESTORS

            (i) Subject to (ii) and (iii) below, at any time during the Demand
Period, as defined in Section 8 below, ASII, upon the written demand of the
Investors, will, as soon as is practicable, use commercially reasonable efforts
to effect the registration under the Securities Act of that number of shares of
the Registrable Securities as are specified by the Investors in such written
demand.

            (ii) ASII's obligations under this Section 2(a) shall be subject to
the limitations set forth below, and ASII (i) shall not be obligated to cause
any special audit to be undertaken in connection with any registration under
this Section 2(a), (ii) at its sole discretion may offer a right to participate
in such registration statement to other holders of ASII's securities, and may
itself participate in such registration, (iii) shall be entitled to postpone for
a reasonable period of time, but not in excess of ninety (90) days, the filing
of any registration statement otherwise required to be prepared pursuant to this
Section 2(a) if ASII is, at such time, conducting or about to conduct an
underwritten public offering of equity securities (or securities convertible
into equity securities) and is advised in writing by its managing underwriter
that such offering would in its opinion be adversely affected by the
registration so requested and (iv) shall be entitled to postpone such requested
registration for up to one hundred twenty (120) days if ASII determines
reasonably and in good faith, in view of the advisability of deferring public
disclosure of material corporate developments or other information, that such
registration and the disclosure required to be made pursuant thereto would not
be in the best interests of ASII at such time.

            (iii) The Investors are entitled to make only one demand for
registration of the Registrable Securities under this Agreement. ASII's
obligation to register the Registrable Securities hereunder shall terminate at
such time as a registration demanded pursuant to this Section 2(a) is deemed
effective.

      (b) REGISTRATION STATEMENT FORM. If any registration demanded pursuant to
this Section 2 which is proposed by ASII to be effected by the filing of a
registration statement on Form S-3 (or any successor or similar short-form
registration statement) shall be in connection with an underwritten public
offering, and if the managing underwriter shall advise ASII in writing that, in
its opinion, the use of another form of registration statement is of material
importance to the success of such proposed offering, then such registration
shall be effected on such other form.

                                       2
<PAGE>

      Upon execution of this Agreement, ASII shall use its reasonable efforts to
register the Registrable Securities when demanded by the Investors, for resale
on or before the expiration of the Demand Period; PROVIDED, HOWEVER, that ASII
shall not be obligated to register the Registrable Securities in any particular
state in which ASII would be required to: (i) qualify to do business as a
foreign corporation and where it would not otherwise be required to so qualify,
(ii) subject itself to taxation in any such jurisdiction, or (iii) execute a
general consent to service of process in any such jurisdiction.

      The registration of the Registrable Securities pursuant to this Agreement
shall not relieve the Investors of their respective obligations pursuant to the
terms of the Stock Purchase Agreement.

      Section 3. EXPENSES OF REGISTRATION. In addition to the fees and expenses
contemplated by Section 4 hereof, all expenses incurred in connection with the
registration pursuant to Section 2 hereof, including without limitation all
registration, filing and qualification fees, printing expenses, fees and
disbursements of counsel for ASII, and expenses of any special audits of ASII's
financial statements incidental to or required by such registration, shall be
borne by ASII, except that ASII shall not be required to pay (a) any fees and
expenses in order to amend or supplement the registration statement or
prospectus to reflect donees or pledges pursuant to Section 4(b) and (b) any
underwriters' fees, discounts or commissions relating to the sale of the
Registrable Securities. ASII shall not, under any circumstances, be required in
connection with a registration hereunder, to (x) conduct any road shows or
similar sales efforts for the Investors, (y) pay any expenses to the Investors
for any road shows or similar sales efforts, or (z) pay any fees and
disbursements of counsel(s) for the Investors.

      Section 4. REGISTRATION PROCEDURES. In the case of the registration
effected by ASII pursuant to this Agreement, ASII will keep each of the
Investors advised in writing as to the initiation of registration and as to the
completion thereof. At its expense, ASII will use reasonable efforts to:

            (a) keep such registration pursuant to Section 2 continuously
      effective for such reasonable period as necessary to permit the Investors
      to complete the distribution in the manner requested by the Investors and
      described in the registration statement relating thereto, but in no event
      beyond the date that is one year from the Closing Date of the Acquisition;

            (b) prepare and file with the SEC such amendments and supplements to
      such registration statement and the prospectus used in connection
      therewith as may be necessary to comply with the provisions of the
      Securities Act, excluding any supplement or amendment required to name
      donees or pledgees of Investors, and to keep such registration statement
      effective for the applicable period of time specified in Section 4(a)
      above;

            (c) furnish such number of prospectuses and other documents incident
      thereto as any of the Investors from time to time may reasonably request
      and assist the Investors in satisfying their prospectus delivery
      obligations by furnishing to any national securities exchange, including
      the American Stock Exchange ("AMEX"), on which the Registrable


                                       3
<PAGE>

      Securities are then listed, copies of the prospectus and each amendment or
      supplement thereto in accordance with Rule 153 under the Securities Act
      (or any comparable rule then in existence);

            (d) obtain the withdrawal of any order suspending the effectiveness
      of a registration statement, or the lifting of any suspension of the
      qualification of any of the Registrable Securities for sale in any
      jurisdiction;

            (e) subject to Section 2(b), register or qualify such Registrable
      Securities for offer and sale under the securities or Blue Sky laws of
      such jurisdictions as any of the Investors reasonably require, and keep
      such registration or qualification effective for the applicable period
      specified in Section 4(a) above;

            (f)   cause   all   Registrable   Securities   covered   by   such
      registrations to be listed on AMEX;

            (g)   notify each of the Investors  promptly of any request by the
      SEC for the amending or supplementing  of the registration  statement or
      prospectus or for additional information;

            (h) advise each of the Investors, after ASII receives notice or
      obtains knowledge of the issuance, of any order by the SEC suspending the
      effectiveness of the registration statement or amendment thereto or of the
      initiation or threatening of any proceeding for that purpose, and promptly
      use reasonable efforts to prevent the issuance of any stop order or to
      obtain its withdrawal promptly if such stop order should be issued;

            (i) use its best efforts to timely file with the SEC all of the
      reports it is required to file under the Exchange Act as a prerequisite to
      availability of Form S-3; and

            (k) notify each Investor at any time a prospectus covered by such
      registration statement is required to be delivered under the Securities
      Act, of the happening of any event of which it has knowledge as a result
      of which the prospectus included in such registration statement, as then
      in effect, includes an untrue statement of a material fact or omits to
      state a material fact required to be stated therein or necessary to make
      the statements therein not misleading in the light of the circumstances
      then existing.

      Section 5. REGISTRATION COVENANTS OF THE INVESTORS. In consideration of
the benefits accruing to them pursuant to this Agreement and in addition to
their other obligations set forth in this Agreement, each of the Investors'
covenants and agrees to:

            (a) cooperate with ASII, its counsel, advisors and other

      connection with any registration effected pursuant to the provisions of

            (f) discontinue sales of Registrable Securities and use of the
      related prospectus following notification by ASII that the registration
      statement must be amended or supplemented;

            (g)   not  use  any   prospectus   other  than  the  most   recent
      prospectus related to the registration statement;

            (h) upon presentation of a stock certificate representing
      Registrable Securities sold under the registration statement, certify that
      the sale was made in accordance with the terms hereof and the plan of
      distribution described in the Registration Statement; and

            (i) notify ASII of any request by the SEC or any state securities
      commission or agency for additional information or for such registration
      statement or prospectus to be amended or supplemented.

its obligations pursuant to Sections 5(a) through (c), any Registrable
Securities held by such Investor may be excluded from the registration statement
and all of such Investor's rights pursuant to the Agreement shall terminate. In
the even that an Investor fails to comply in any material respect with its
obligations pursuant to Sections 5(d) through (i), all of such Investor's rights
pursuant to this Agreement shall terminate other than with respect to
Registrable Shares then registered on a Registration Statement.

      Section 6.  INDEMNIFICATION.

            (a) ASII shall indemnify and hold harmless each of the Investors
      against any losses, claims, damages or liabilities, joint or several, to
      which such Investor may become subject under the Securities Act or
      otherwise, insofar as such losses, claims, damages or liabilities (or
      actions in respect thereof) arise out of or are based upon any untrue
      statement or alleged untrue statement of any material fact contained in
      the registration statement under which such Registrable Securities were
      registered under the Securities Act, any preliminary prospectus or final
      prospectus contained therein, or any amendment


                                       5
<PAGE>

      or supplement thereof, or arise out of or are based upon the omission or
      alleged omission to state therein a material fact required to be stated
      therein or necessary to make the statements therein not misleading, or any
      violation by ASII of any rule or regulation promulgated under the
      Securities Act or any state securities law applicable to ASII and relating
      to action or inaction required of ASII in connection with any such
      registration, and will reimburse each such Investor for any reasonable
      legal and any other expenses incurred in connection with investigating,
      defending or settling any such claim, loss, damage, liability or action;
      PROVIDED, HOWEVER, that ASII will not be liable in any such case to the
      extent that any such claim, loss, damage or liability arises out of or is
      based on (i) the failure of any Investor to comply in any material respect
      with its obligations pursuant to Sections 5(d) through (i), or (ii) any
      untrue statement or omission based upon information furnished to or
      requested by ASII by or from any Investor for use therein.

            (b) Each Investor will, if Registrable Securities held by or
      issuable to such Investor are included in the securities as to which such
      registration is being effected, indemnify and hold harmless ASII, each of
      its directors and officers, each person who controls ASII, and each other
      Investor, against all claims, losses, expenses, damages and liabilities
      (or actions in respect thereof) arising out of or based on (i) the failure
      of any Investor to comply in any material respect with its obligations
      pursuant to Sections 5(d) through (i), or (ii) any untrue statement (or
      alleged statement) of a material fact contained in any such registration
      statement, prospectus, offering circular or other document or any omission
      (or alleged omission) to state therein a material fact required to be
      stated therein or necessary to make the statements therein not misleading,
      and will reimburse ASII, each person who controls ASII, such directors or
      officers, or such other Investors for any reasonable legal or any other
      expenses incurred in connection with investigating, defending or settling
      any such claim, loss, damage, liability or action, in each case to the
      extent, but only to the extent that such untrue statement (or alleged
      untrue statement) or omission (or alleged omission) is made in such
      registration statement, prospectus, offering circular or other document in
      reliance upon and in conformity with information furnished to or requested
      by ASII by or from such Investor specifically for use therein; PROVIDED,
      HOWEVER, the total amount for which any Investor shall be liable under
      this Section 6(b) shall not in any event exceed the aggregate proceeds
      received by such Investor from the sale of Registrable Securities sold by
      such Investor in such registration.

            (c) Each party entitled to indemnification under this Section 6 (the
      "INDEMNIFIED PARTY") shall give notice to the party required to provide
      indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified
      Party has actual knowledge of any claims as to which indemnity may be
      sought, and shall permit the Indemnifying Party to assume the defense of
      any such claim or any litigation resulting therefrom, provided that
      counsel for the Indemnifying Party, who shall conduct the defense of such
      claim or litigation, shall be approved by the Indemnified Party (whose
      approval shall not be unreasonably withheld), and the Indemnified Party
      may participate in such defense at such party's expense, and provided
      further that the failure of any Indemnified Party to give notice as
      provided herein shall not relieve the Indemnifying Party of its
      obligations hereunder, unless such failure resulted in actual detriment to
      the Indemnifying Party. No Indemnifying Party, in the defense of any such
      claim or litigation, shall, except with the

                                       6
<PAGE>

      consent of each Indemnified Party, consent to entry of any judgment or
      enter into any settlement which does not include as an unconditional term
      thereof the giving by the claimant or plaintiff to such Indemnified Party
      of a full and unconditional release from all liability in respect of such
      claim or litigation.

            (d) If the indemnification provided for in this Section 6 is held by
      a court of competent jurisdiction to be unavailable to an Indemnified
      Party with respect to any loss, liability, claim, damage or expense
      referred to therein, then the Indemnifying Party, in lieu of indemnifying
      such Indemnified Party thereunder, shall contribute the amount paid or
      payable by such Indemnified Party as a result of such loss, liability,
      claim, damage or expense in such proportion as is appropriate to reflect
      the relative fault of the Indemnifying Party on the one hand and of the
      Indemnified Party on the other hand in connection with the statements or
      omissions which resulted in such loss, liability, claim, damage or expense
      as well as any other relevant equitable considerations. The relevant fault
      of the Indemnifying Party and the Indemnified Party shall be determined by
      reference to, among other things, whether the untrue or alleged untrue
      statement of a material fact or the omission to state a material fact
      relates to information supplied by the Indemnifying Party or by the
      Indemnified Party and the parties' relative intent, knowledge, access to
      information and opportunity to correct or prevent such statement or
      omission. Notwithstanding the foregoing, the amount any Investor shall be
      obligated to contribute pursuant to this Section 6(d) shall be limited to
      an amount equal to the proceeds to such Investor of the Registrable
      Securities sold pursuant to the registration statement which gives rise to
      such obligation to contribute (less the aggregate amount of any damages
      which the Investor has otherwise been required to pay in respect of such
      loss, claim, damage, liability or action or any substantially similar
      loss, claim, damage, liability or action arising from the sale of such
      Registrable Securities).

            (e) The indemnification provided by this Section 6 shall be a
      continuing right to indemnification and shall survive the registration and
      sale of any securities by any person entitled to indemnification hereunder
      and the expiration or termination of this Agreement.

      Section 7. CERTIFICATE LEGENDS. Within five (5) business days after a
registration statement filed under Section 2 hereof becomes effective, ASII will
notify each Investor. Upon receipt of such notice, each Investor may return its
certificate representing the Registrable Securities and request that ASII issue
a new certificate in such Investor's name free of any restrictive legend
relating to compliance with federal securities laws and ASII shall take all
reasonable steps to do so; PROVIDED, HOWEVER, that ASII shall only be obligated
to remove the legend for that number of Registrable Securities which any
Investor represents is being sold pursuant to the registration statement.

      Section 8. TERMINATION OF RIGHTS. All rights of the Investors to demand
registration of the Registrable Securities under this Agreement shall exist
during the period (the "Demand Period") commencing on the date hereof and
terminating at 5:00 P.M. Eastern time on the date one year after the date
hereof.

      time a written request from the Investor that the Company effect any
      registration with respect to at least thirty percent (30%) of the
      Registrable Securities, the Company will:

                  (i) promptly give written notice of the proposed registration
            to all Stockholders and the DCI Stockholders; and

                  (ii) as soon as practicable, use commercially reasonable
            efforts to effect such registration (including, without limitation,
            filing post-effective amendments, obtaining appropriate
            qualifications under applicable blue sky or other state securities
            laws, and ensuring appropriate compliance with the Securities Act)
            as would permit or facilitate the sale and distribution of all or
            such portion of such Registrable Securities as are specified in such
            request by the Investor, together with all or such portion of the
            Registrable Securities of any Stockholder joining in such request as
            are specified in a written request received by the Company within
            thirty (30) days after the written notice from the Company referred
            to in subclause (i) above is mailed or delivered.

      The Company shall not be obligated to effect, or to take any action to
effect, any such registration pursuant to this Section 1.2:

                  (A) (i) In any particular jurisdiction in which the Company
            would be required to execute a general consent to service of process
            in effecting such registration, qualification, or compliance, unless
            the Company is already subject to service in such jurisdiction and
            except as may be required by the Securities Act, or (ii) in any
            particular jurisdiction in which the Company is not qualified to do
            business or would be required to do business as a foreign
            corporation and where it would not otherwise be required to so
            qualify, or (iii) subject itself to taxation in any such
            jurisdiction;

                  (B) After the Company has initiated two such registrations
            pursuant to this Section 1.2(a) (counting for these purposes only
            registrations which have been declared or ordered effective and
            registrations which have been withdrawn by the Investor or the
            Stockholders and as to which the Investor or any other Stockholder
            has not elected to bear the Registration Expenses pursuant to
            Section 1.4); or

                                       3
<PAGE>


                  (C) If the Company is unable to obtain the commitment of an
            underwriter to firmly underwrite the offering.

            (b) FILING OF REGISTRATION STATEMENT. Subject to the foregoing
      clauses (A) through (C), the Company shall file a registration statement
      covering the Registrable Securities so requested to be registered as soon
      as practicable after receipt of the request or requests of the Investor;
      PROVIDED, HOWEVER, the Company: (i) at its sole discretion, may offer a
      right to participate in such registration statement at such time to the
      DCI Stockholders, (ii) shall be entitled to postpone for a reasonable
      period of time, but not in excess of ninety (90) days, the filing of any
      registration statement otherwise required to be prepared pursuant to this
      Section 1.2 if Company is, at such time, conducting or about to conduct an
      underwritten public offering of equity securities (or securities
      convertible into equity securities) and is advised in writing by its
      managing underwriter that such offering would in its opinion be adversely
      affected by the registration so requested, and (iii) shall be entitled to
      postpone such required registration for up to ninety (90) days if the
      Company determines reasonably and in good faith, in view of the
      advisability of deferring public disclosure of material corporate
      developments or other information that such registration and the
      disclosure required to be made pursuant thereto would not be in the best
      interest of the Company at such time.

      The registration statement filed pursuant to the request of the Investor
may, subject to the provisions of Sections 1.2(b) and 1.12 hereof, include other
securities of the Company, with respect to which registration rights have been
granted, and may include securities of the Company being sold for the account of
the Company.

            (c) PROCEDURES. If Stockholders or the DCI Stockholders shall
      request inclusion in any registration pursuant to this Section 1.2, the
      Company shall offer to include such securities in the underwriting and may
      condition such offer on its acceptance of the further applicable
      provisions of this Section 1 (including Section 1.12 hereof). The Company
      shall (together with all Stockholders) enter into an underwriting
      agreement in customary form with the representative of the underwriter or
      underwriters selected by the Company for such underwriting.
      Notwithstanding any other provision of this Section 1.2, if the
      representative of the underwriters advises the Investor in writing that
      marketing factors require a limitation on the number of shares to be
      underwritten, the number of shares to be included in the underwriting or
      registration shall be allocated as set forth in Section 1.12 hereof. If a
      person who has requested inclusion in such registration as provided above
      does not agree to the terms of any such underwriting, such person shall be
      excluded therefrom by written notice from the Company or the underwriter.
      Any Registrable Securities or other securities excluded shall also be
      withdrawn from such registration. If shares are so withdrawn from the
      registration and if the number of shares to be included in such
      registration was previously reduced as a result of marketing factors
      pursuant to this Section 1.2(c), then the Company shall offer to all
      Stockholders who have retained rights to include securities in the
      registration the right to include additional securities in the
      registration in an aggregate amount equal to the number of shares so
      withdrawn, with such shares to be allocated among such Stockholders
      requesting additional inclusion in accordance with Section 1.12 hereof.

      1.3 COMPANY REGISTRATIONS.

            (a) If the Company shall determine to register any of its securities
      either for its own account or the account of a security holder exercising
      demand registration rights (other than pursuant to Section 1.2 hereof),
      other than a registration relating solely to employee benefit plans, a
      registration relating solely to a Rule 145 transaction, or a registration
      on any registration form that does not permit secondary sales, the Company
      will:

                  (i) promptly give to all Stockholders written notice thereof;
            and

                  (ii) include in such registration (and any related
            qualification under blue sky laws or other compliance), except as
            set forth in Section 1.3(b) and Section 1.12 hereof, and in any
            underwriting involved therein, all the Registrable Securities
            specified in a written request or requests, made by any Stockholder
            and received by the Company within thirty (30) days after the
            written notice from the Company described in clause (i) above is
            mailed or delivered by the Company. Such written request may specify
            all or a part of a Stockholder's Registrable Securities.

            (b) UNDERWRITING. If the registration of which the Company gives
      notice is for a registered public offering involving an underwriting, the
      Company shall so advise the Stockholders as a part of the written notice
      given pursuant to Section 1.3(a)(i) hereof. In such event, the right of
      any Stockholder to registration pursuant to this Section 1.3 shall be
      conditioned upon such Stockholder's participation in such underwriting and
      the inclusion of such Stockholder's Registrable Securities in the
      underwriting to the extent provided herein. All Stockholders proposing to
      distribute their securities through such underwriting shall (together with
      the Company) enter into an underwriting agreement in customary form with
      the representative of the underwriter or underwriters selected by the
      Company.

      Notwithstanding any other provision of this Section 1.3, if the
representative of the underwriters advises the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
representative may exclude all Registrable Securities from, or limit the number
of Registrable Securities to be included in, the registration and underwriting.
The Company shall so advise all Stockholders of securities holders requesting
registration, and the number of shares that are entitled to be included in the
registration and underwriting (other than on behalf of the Company) as set forth
in Section 1.12 hereof. If any person does not agree to the terms of any such
underwriting, he shall be excluded therefrom by written notice from the Company
or the underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

      If shares are so withdrawn from the registration and if the number of
shares of Registrable Securities to be included in such registration was
previously reduced as a result of marketing factors, the Company shall then
offer to all persons who have retained the right to include securities in the
registration the right to include additional securities in the registration in
an


                                       5
<PAGE>

aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among the persons requesting additional inclusion in accordance
with Section 1.12 hereof.

      1.4 EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Section 1.3 hereof, and the two registrations pursuant to Section 1.2 hereof
shall be borne by the Company; provided, however, that if the Investor or any
other Stockholder pays all the Registration Expenses for any registration
proceeding begun pursuant to Section 1.2 hereof which is subsequently withdrawn
by the Investor, such registration proceeding shall not be counted as a
requested registration pursuant to Section 1.2 hereof. Notwithstanding the
foregoing, in the event that a withdrawal is based upon material adverse
information relating to the Company that is different from the information known
or available (upon request from the Company or otherwise) to the Investor at the
time of its request for registration under Section 1.2 hereof, the Company will
bear the Registration Expenses, and such registration shall not be treated as a
counted registration for purposes of Section 1.2 hereof, even though the
Investor does not bear the Registration Expenses for such registration. All
Selling Expenses relating to securities so registered shall be borne by the
holders of such securities pro rata on the basis of the amount of securities so
registered on their behalf. The Company shall not, under any circumstances, be
required in connection with a registration hereunder, to (x) conduct any road
shows or similar sales efforts for the Investor, (y) pay any expenses to the
Investor for any road shows or similar sales efforts, or (z) pay any fees and
disbursements of counsel for the Investor.

      1.5 REGISTRATION PROCEDURES. In the case of each registration effected by
the Company pursuant to Section 1, the Company will keep each Stockholder
advised in writing as to the initiation of each registration and as to the
completion thereof. At its expense, the Company will use its best efforts to:

            (a) Keep such registration effective for a period of one hundred
      eighty (180) days or until the Stockholders have completed the
      distribution described in the registration statement relating thereto,
      whichever first occurs; provided, however, that such one hundred eighty
      (180) day period shall be extended for a period of time equal to the
      period the Stockholder refrains from selling any securities included in
      such registration at the request of an underwriter of common stock (or
      other securities) of the Company.

            (b) Prepare and file with the Commission such amendments and
      supplements to such registration statement and the prospectus used in
      connection with such registration statement as may be necessary to comply
      with the provisions of the Securities Act with respect to the disposition
      of all securities covered by such registration statement;

            (c) Furnish such number of prospectuses and other documents incident
      thereto, including any amendment of or supplement to the prospectus, as a
      Stockholder or Underwriter from time to time may reasonably request in
      order to facilitate the public offering of such securities;

            (d) Notify each seller of Registrable Securities covered by such
      registration statement at any time when a prospectus relating thereto is
      required to be delivered under the


                                       6
<PAGE>

      Securities Act of the happening of any event as a result of which the
      prospectus included in such registration statement, as then in effect,
      includes an untrue statement of a material fact or omits to state a
      material fact required to be stated therein or necessary to make the
      statements therein not misleading or incomplete in the light of the
      circumstances then existing, and at the request of any such seller,
      prepare and furnish to such seller a reasonable number of copies of a
      supplement to or an amendment of such prospectus as may be necessary so
      that, as thereafter delivered to the purchasers of such shares, such
      prospectus shall not include an untrue statement of a material fact or
      omit to state a material fact required to be stated therein or necessary
      to make the statements therein not misleading or incomplete in the light
      of the circumstances then existing; and

            (e) In connection with any underwritten offering pursuant to a
      registration statement filed pursuant to Section 1.2 hereof, the Company
      will enter into an underwriting agreement reasonably necessary to effect
      the offer and sale of common stock, provided such underwriting agreement
      contains customary indemnification provisions and provided further that if
      the underwriter so requests the underwriting agreement will contain
      customary contribution provisions.

      1.6 INDEMNIFICATION.

            (a) The Company will indemnify the Investor, each of its officers,
      directors and partners, legal counsel, and accountants and each person
      controlling the Investor within the meaning of section 15 of the
      Securities Act, to the extent any registration, qualification, or
      compliance is effected on its behalf, pursuant to this Section 1, and each
      underwriter, if any, and each person who controls within the meaning of
      section 15 of the Securities Act any underwriter, against all expenses,
      claims, losses, damages, and liabilities (or actions, proceedings, or
      settlements in respect thereof) arising out of or based on any untrue
      statement (or alleged untrue statement) of a material fact contained in
      any prospectus, offering circular, or other document (including any
      related registration statement, notification, or the like) incident to any
      such registration, qualification, or compliance, or based on any omission
      (or alleged omission) to state therein a material fact required to be
      stated therein or necessary to make the statements therein not misleading,
      or any violation by the Company of the Securities Act, the Exchange Act,
      any state securities laws or any rule or regulation thereunder applicable
      to the Company and relating to action or inaction required of the Company
      in connection with any such registration, qualification, or compliance,
      and will reimburse the Investor, each of its officers, directors,
      partners, legal counsel, and accountants and each person controlling the
      Investor, each such underwriter, and each person who controls any such
      underwriter, for any legal and any other expenses reasonably incurred in
      connection with investigating and defending or settling any such claim,
      loss, damage, liability, or action, provided that the Company will not be
      liable in any such case to the extent that any such claim, loss, damage,
      liability, or expense arises out of or is based on any untrue statement or
      omission to the Company by the Investor, any Stockholder or any
      underwriter and stated to be specifically for use therein. It is agreed
      that the indemnity agreement contained in this Section 1.6(a) shall not
      apply to amounts paid in settlement of any such loss, claim, damage,
      liability, or action if such settlement is effected without the consent of
      the Company (which consent shall not be unreasonably withheld).

                                       7
<PAGE>

            (b) The Investor will, to the extent Registrable Securities, are
      included in the securities as to which such registration, qualification,
      or compliance is being effected, indemnify the Company, each of its
      directors, officers, stockholders, legal counsel, and accountants and each
      underwriter, if any, of the Company's securities covered by a registration
      statement, each person who controls the Company or such underwriter within
      the meaning of section 15 of the Securities Act, and each of their
      officers, directors, and partners, against all claims, losses, damages and
      liabilities (or actions in respect thereof) arising out of or based on any
      untrue statement (or alleged untrue statement) of a material fact
      contained in any such registration statement, prospectus, offering
      circular, or other document, or any omission (or alleged omission) to
      state therein a material fact required to be stated therein or necessary
      to make the statements therein not misleading, and will reimburse the
      Company, its directors, officers, partners, legal counsel, and
      accountants, persons, underwriters, or control persons for any legal and
      any other expenses reasonably incurred in connection with investigating or
      defending any such claim, loss, damage, liability, or action, in each case
      to the extent, but only to the extent, that such untrue statement (or
      alleged untrue statement) or omission (or alleged omission) is made in
      such registration statement, prospectus, offering circular, or other
      document in reliance upon and in conformity with information provided to
      the Company by the Investor and stated to be specifically for use therein;
      PROVIDED, however, that the obligations of the Investor hereunder shall
      not apply to amounts paid in settlement of any such claims, losses,
      damages, or liabilities (or actions in respect thereof) if such settlement
      is effected without the consent of the Investor (which consent shall not
      be unreasonably withheld).

            (c) Each party entitled to indemnification under this Section 1.6
      (the "Indemnified Party") shall give notice to the party required to
      provide indemnification (the "Indemnifying Party") promptly after such
      Indemnified Party has actual knowledge of any claim as to which indemnity
      may be sought, and shall permit the Indemnifying Party to assume the
      defense of such claim or any litigation resulting therefrom, provided that
      counsel for the Indemnifying Party, who shall conduct the defense of such
      claim or any litigation resulting therefrom, shall be approved by the
      Indemnified Party (whose approval shall not unreasonably be withheld), and
      the Indemnified Party may participate in such defense at such party's
      expense, and provided further that the failure of any Indemnified Party to
      give notice as provided herein shall not relieve the Indemnifying Party of
      its obligations under this Section 1, to the extent such failure is not
      prejudicial. No Indemnifying Party, in the defense of any such claim or
      litigation, shall, except with the consent of each Indemnified Party,
      consent to entry of any judgment or enter into any settlement that does
      not include as an unconditional term thereof the giving by the claimant or
      plaintiff to such Indemnified Party of a release from all liability in
      respect to such claim or litigation. Each Indemnified Party shall furnish
      such information regarding itself or the claim in question as an
      Indemnifying Party may reasonably request in writing and as shall be
      reasonably required in connection with defense of such claim and
      litigation resulting therefrom.

            (d) If the indemnification provided for in this Section 1.6 is held
      by a court of competent jurisdiction to be unavailable to an Indemnified
      Party with respect to any loss, liability, claim, damage, or expense
      referred to herein, then the Indemnifying Party, in lieu of indemnifying
      such Indemnified Party hereunder, shall contribute to the amount paid or
      payable by such Indemnified Party as a result of such loss, liability,
      claim, damage, or expense in such proportion as is appropriate to reflect
      the relative fault of the Indemnifying Party on the one hand


                                       8
<PAGE>

      and of the Indemnified Party on the other in connection with the
      statements or omissions that resulted in such loss, liability, claim,
      damage, or expense as well as any other relevant equitable considerations.
      The relative fault of the Indemnifying Party and of the Indemnified Party
      shall be determined by reference to, among other things, whether the
      untrue or alleged untrue statement of a material fact or the omission to
      state a material fact relates to information supplied by the Indemnifying
      Party or by the Indemnified Party and the parties' relative intent,
      knowledge, access to information, and opportunity to correct or prevent
      such statement or omission.

            (e) Notwithstanding the foregoing, to the extent that the provisions
      on indemnification and contribution contained in the underwriting
      agreement entered into in connection with the underwritten public offering
      are in conflict with the foregoing provisions, the provisions in the
      underwriting agreement shall control.

      1.7 INFORMATION BY STOCKHOLDER. Each Stockholder of Registrable Securities
shall furnish to the Company such information regarding such Stockholder and the
distribution proposed by such Stockholder as the Company may reasonably request
and as shall be reasonably required in connection with any registration,
qualification, or compliance referred to in this Section 1.

      1.8 LIMITATIONS ON REGISTRATION OF ISSUES OF SECURITIES. Without the
consent of the Investor and except for the rights granted to the DCI
Stockholders, the Company shall not grant any registration rights which are
senior to the rights of the Investor hereunder.

      1.9 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the
Registrable Securities to the public without registration, the Company agrees to
use its best efforts to:

            (a) Make and keep public information regarding the Company
      available, as those terms are understood and defined in Rule 144 under the
      Securities Act, at all times;

            (b) File with the Commission in a timely manner all reports and
      other documents required of the Company under the Securities Act and the
      Exchange Act at any time;

            (c) So long as the Investor owns any Registrable Securities, furnish
      to the Investor forthwith upon written request a written statement by the
      Company as to its compliance with the reporting requirements of Rule 144,
      and of the Securities Act and the Exchange, a copy of the most recent
      annual or quarterly report of the Company, and such other reports and
      documents so filed as the Investor may reasonably request in availing
      itself of any rule or regulation of the Commission allowing the Investor
      to sell any such securities without registration.

      1.10 TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause
the Company to register securities granted to the Investor by the Company under
this Section 1 may be transferred or assigned by the Investor only to a
transferee or assignee of not less than fifty-one percent (51%) of the
Registrable Securities (as presently constituted and subject to subsequent
adjustments for stock splits, stock dividends, reverse stock splits, and the
like), provided that the


                                       9
<PAGE>

Company is given written notice at the time of or within a reasonable time after
such transfer or assignment, stating the name and address of the transferee or
assignee and identifying the securities with respect to which such registration
rights are being transferred or assigned, and, provided further, that the
transferee or assignee of such rights assumes the obligations of the Investor
under this Agreement in a writing delivered to the Company. Upon consummation of
such transfer or assignment, the Investor shall no longer be able to exercise
the rights and shall not incur further obligations attributed to the "Investor"
hereunder.

      1.11 "MARKET STAND-OFF" AGREEMENT. If requested by the Company and an
underwriter of common stock (or other securities) of the Company, the
Stockholders shall not sell or otherwise transfer or dispose of any common stock
(or other securities) of the Company held by such holder (other than those
included in the registration) during the one hundred eighty (180) day period
following the effective date of a registration statement of the Company filed
under the Securities Act; provided, that all officers and directors of the
Company and all other persons holding five percent (5%) or more of the Company's
outstanding stock enter into similar agreements and provided further, that the
Stockholders shall not be so prohibited from selling or otherwise transferring
or disposing of any common stock (or other securities) of the Company if a
Stockholder seeks inclusion in such registration but is unable to participate as
a result of the limitations provided in Section 1.3(b) and Section 1.12 of this
Agreement.

      The obligations described in this Section 1.11 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar
forms that may be promulgated in the future. The Company may impose
stop-transfer instructions with respect to the shares (or securities) subject to
the foregoing restriction until the end of such one hundred eighty (180) day
period.

      1.12 ALLOCATION OF REGISTRATION OPPORTUNITIES. In any circumstance in
which all of the Registrable Securities and securities of the Company held by
others who have been granted registration rights, including the DCI
Stockholders, (the "Other Shares") are the subject of a request to be included
in a registration and cannot be so included as a result of limitations on the
aggregate number of shares of Registrable Securities and Other Shares that may
be so included, the number of shares of Registrable Securities and Other Shares
that may be so included shall be allocated among those requesting inclusion of
shares as follows:

            (a) Upon a request for registration by the Investor pursuant to
      Section 1.2, the Other Shares to be included in such registration shall be
      reduced pro rata among the holders of such shares to the extent necessary
      to accommodate the sale of ALL of the Registrable Securities by the
      Investor and Stockholders, even if such reduction may eliminate the
      opportunity for the sale of Other Shares. If, after the Other Shares are
      eliminated from such registration, limitations remain on the Registrable
      Securities to be included in such registration, the Registrable Securities
      to be included shall be reduced on a pro rata basis among the Investor and
      the Stockholders.

            (b) Upon a registration proposed by another holder of Company
      securities pursuant to Section 1.3, the Registrable Securities to be
      included in such registration shall be



                                       10
<PAGE>

      reduced pro rata among the Investor and the Stockholders to the extent
      necessary to accommodate the sale of ALL of the Other Shares by such other
      holder, even if such reduction may eliminate the opportunity for the sale
      of the Registrable Securities.

            (c) Upon a registration proposed by the Company pursuant to Section
      1.3, the number of Registrable Securities and Other Shares to be included
      in such registration shall, AFTER the inclusion of all shares proposed for
      sale by the Company, be allocated pro rata on the basis of the number of
      shares of Registrable Securities and Other Shares that would be held by
      the Investor, the holders, and stockholders of Other Shares, assuming
      conversion; provided, however, so that such allocation shall not operate
      to reduce the aggregate number of Registrable Securities to be included in
      such registration below twenty-five percent (25%) of the total amount of
      securities included in such offering. If the Investor, the Stockholder, or
      other security holders do not request inclusion of the maximum number of
      shares of Registrable Securities and Other Shares allocated to him
      pursuant to the above-described procedure, the remaining portion of his
      allocation shall be reallocated among those requesting Stockholders whose
      allocations did not satisfy their requests pro rata on the basis of the
      number of shares of Registrable Securities and Other Shares which would be
      held by such Stockholders, assuming conversion, and this procedure shall
      be repeated until all of the shares of Registrable Securities and Other
      Shares which may be included in the registration on behalf of the
      Stockholders have been so allocated.

            (d) The Company shall not limit the number of Registrable Securities
      to be included in a registration pursuant to this Agreement in order to
      include shares held by stockholders with no registration rights. To
      facilitate the allocation of Securities in accordance with the above
      provisions, the Company or the Underwriters may round the number of
      Securities allocated to any Stockholder to the nearest 100 Securities.

      1.13 DELAY OF REGISTRATION. The Investor shall not have any right to take
any action to restrain, enjoin, or otherwise delay any registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

      1.14 TERMINATION OF REGISTRATION RIGHTS. The right of the Investor to
request registration or inclusion in any registration pursuant to Section 1.2 or
1.3 hereof shall terminate on the closing of an acquisition of the Registrable
Securities in exchange for publicly traded stock of another entity.

                                   SECTION 2
                            COVENANTS OF THE COMPANY

      The Company hereby covenants and agrees, so long as the Investor owns
Securities or Registrable Securities representing not less than fifty percent
(50%) of the total potential amount of Registrable Securities, as follows:

      2.1 BASIC FINANCIAL INFORMATION. The Company will furnish to the Investor
the following upon request:

                                       11
<PAGE>

            (a) Within 90 days after the end of each fiscal year of the Company,
      a balance sheet of the Company as of the end of such fiscal year and
      statements of income and of changes in financial condition of the Company
      for such year (A) prepared in accordance with generally accepted
      accounting principles, (B) audited by an independent accounting firm
      reasonably acceptable to Investor, and (C) including such other
      information as is necessary to verify the financial conditions of the
      Company.

            (b) Within 30 days after the end of each calendar month (other than
      a calendar month during which any fiscal quarter or fiscal year of the
      Company ends), an unaudited balance sheet of the Company as of the end of
      such month and unaudited statements of income and of changes in financial
      condition of the Company for such month and for the current fiscal year to
      the end of such month;

            (c) As soon as available, but in any event within 30 days after
      commencement of each new fiscal year, a business plan that shall contain
      projected quarterly and annual financial statements and quarterly and
      annual operating and capital budgets for such fiscal year, which such plan
      shall be submitted to Company's Board of Directors for approval within
      such time; and

            (d) With reasonable promptness, such other information and financial
      data concerning the Company as Investor may reasonably request, including,
      without limitation, quarterly and annual budgets and summaries of
      financial plans.

      2.2 FUTURE INVESTMENTS. In the event Company shall commence a private
equity financing within five years subsequent to the date of this Agreement,

Subordinated Debenture Due February 7, 2005" of the Company. The Stated Maturity
of this Debenture shall be February 7, 2005, and the principal amount of this
Debenture shall bear interest, as set forth below, at the rate per annum set
forth in the preceding sentence, until the principal hereof is paid in full and
(to the extent that the payment of such interest shall be legally enforceable)
such interest shall accrue on any overdue installment of interest at a rate of
13% per annum.

      This Debenture may be sold, transferred, assigned or hypothecated, in

dissolution of either such entity, or (d) a purchaser, or officers of a
purchaser, of substantially all of the assets of KCEP or KCEP Ventures II, L.P.,
and shall be so transferable only upon the books of the Company which the
Company shall cause to be maintained for such purpose, provided, however, any
such transfer is in an amount which permits the transferee to convert a minimum
of 10,000 shares of Common Stock, unless otherwise consented to by the Company,
in which event the Company shall issue a new Debenture to each such Person,
which new Debenture shall contain substantially identical rights, limitations,
terms and conditions as this Debenture.

      Except as otherwise provided in this ARTICLE III, this Debenture shall
bear interest, payable quarterly on April 30, July 31, October 31 and January 31
of each year, commencing April 30, 2000. Interest on this Debenture shall be

an Opinion of Counsel to the effect that no withholding is required under the
applicable provisions of such income tax laws of the United States, then the
Company shall not withhold any amounts from such payments.

                                   ARTICLE IV

SECTION 5.3 CORPORATE EXISTENCE

      Subject to ARTICLE VII, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence,
and its corporate authority and rights (charter and statutory); PROVIDED,

SECTION 5.6 DIVIDEND, REPURCHASE AND REDEMPTION RESTRICTIONS

      So long as this Debenture shall be outstanding, the Company will not

Directors) of such property at the time of declaration (in the case of
dividends) or at the time of payment or distribution.

      Notwithstanding the foregoing provisions, the Company may purchase,
acquire or issue cash in respect of any fractional shares resulting from any
stock dividend, stock split, stock combination, recapitalization or
reorganization, provided that the aggregate amount so paid shall be included as
a payment in any calculation under the provisions of this SECTION 5.6.

<PAGE>

      The Company may omit in any particular instance to comply with any

such instance or generally waive compliance with such covenant or condition, but
no such waiver shall extend to or affect such covenant or condition except to
the extent so expressly waived, and, until such waiver shall become effective,

letter or statement such default or defaults and the nature thereof, it being
understood that such accountants shall not be liable directly or indirectly for
failure to obtain knowledge of any such default or defaults.

      any other jurisdiction against the Holder in connection with any claim,
      action or proceeding which may be brought by the Holder in order to

subject to the other provisions of this Debenture and the Subordination
Agreement, declare the principal of this Debenture to be immediately due and
payable, by a notice in writing to the Company, and upon any such declaration
such principal shall become immediately due and payable.

<PAGE>

      At any time after such a declaration of acceleration has been made, the

declaration and its consequences if:

            (1) the Company has paid or deposited a sum sufficient to pay:

                  (A) All overdue installments of interest on this Debenture,

                  (B) the principal of this Debenture which has become due
            otherwise than by such declaration of acceleration and interest
            thereon at the rate borne by this Debenture,

            annum, and

                  (D) the reasonable compensation, expenses, disbursements and
            advances of agents and counsel; and

            (2) all Events of Default, other than the non-payment of the
      principal of this Debenture which has become due solely by such
      acceleration, have been cured or waived by the Holder.

      No such rescission shall affect any subsequent default or impair any right
consequent thereon.

      Subject to the other provisions of this Debenture and the Subordination
Agreement, the Holder may not elect to accelerate the maturity of this Debenture
until it has first notified the agent or trustee of Superior Indebtedness in
writing (and provided a copy in writing of such notice to the Company) and shall
not take any of the following actions for a period ending on the earlier of (i)
180 days after the receipt of such notice by the holders of Superior
Indebtedness and the Company or (ii) payment in full of the Superior
Indebtedness:

                  (A) commencement or continuation of any action or proceeding
            against the Company, whether to reduce the claims of the Holder to
            judgment or to enforce the terms of this Debenture or otherwise;

                  (B) any act to obtain possession of property of the Company or
            to exercise control over property of the Company; or

                  (C) any act to create, perfect or enforce any lien against
            property of the Company.

SECTION 6.3 COLLECTION OF INDEBTEDNESS

      The Company covenants that if:

            (1) default is made in the payment of any installment of interest on
      this Debenture when such interest becomes due and payable and such default
      continues for a period of 30 days, or
<PAGE>

            (2) default is made in the payment of the principal of this
      Debenture at the Maturity thereof,

the Company will, upon demand of the Holder, pay to it, the whole amount then
due and payable on this Debenture for principal and interest, with interest upon
the overdue principal and, to the extent that payment of such interest shall be
legally enforceable, upon overdue installments of interest, at a rate of 13% per
annum; and, in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Holder, its agents and
counsel.

SECTION 6.4 UNCONDITIONAL RIGHT OF THE HOLDER TO RECEIVE PRINCIPAL AND
            INTEREST AND TO CONVERT

      Subject to the provisions of ARTICLE VIII hereof and the Subordination
Agreement, the Holder shall have the right, which is absolute and unconditional,
to receive payment of the principal of and interest on this Debenture on the
Stated Maturity (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment and the right to convert
this Debenture in accordance with ARTICLE IX and to institute suit for its
enforcement, and such rights shall not be impaired without the consent of the
Holder.

SECTION 6.5 RESTORATION OF RIGHTS AND REMEDIES

      If the Holder has instituted any proceeding to enforce any right or remedy
under this Debenture and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Holder, then and in every
such case, the Company and the Holder shall, subject to any determination in
such proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Holder shall
continue as though no such proceeding (except for the situation in which there
was a determination adverse to the Holder) had been instituted.

SECTION 6.6 RIGHTS AND REMEDIES CUMULATIVE

      No right or remedy herein conferred upon or reserved to the Holder is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

SECTION 6.7 DELAY OR OMISSION NOT WAIVER

      No delay or omission of the Holder of this Debenture to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or
remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Holder
may be exercised from time to time, and as often as may be deemed expedient.

SECTION 8.2 PAYMENTS TO THE HOLDER

      No payment on account of principal of or interest on this Debenture shall
be made if any default or event of default with respect to any Superior
Indebtedness which permits the holders thereof (or any agent acting on their
behalf) to accelerate the maturity thereof shall have occurred and be
continuing.

      Upon any payment by the Company, or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or total or partial liquidation or
reorganization of the Company, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, all amounts due or to
become due upon all Superior Indebtedness (including principal, premium, if any,
and interest due thereon) shall first be paid in full, or payment thereof
provided for, in money or money's worth, in accordance with its terms, before
any payment is made on account of the principal or interest on this Debenture;
and upon any such dissolution or winding-up or liquidation or reorganization or
any payment by the Company, or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the Holder would
be entitled, except for the provisions of this ARTICLE VIII, any such payment or
distribution of assets shall be paid, or delivered, as the case may be, by the
Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or
other Person making such payment or distribution directly to the holders of
Superior Indebtedness or their representative or representatives or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing any Superior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay all Superior Indebtedness
in full, in money or money's worth, after giving effect to any concurrent
payment or distribution to or for the holders of Superior Indebtedness, before
any payment or distribution is made to the Holder.

      In the event that, notwithstanding the preceding paragraphs, any payment
by, or distribution of assets of, the Company of any kind or character, whether
in cash, property or securities, shall be received by the Holder before all
Superior Indebtedness is paid in full, such payment or distribution shall be
paid over or delivered to the holders of Superior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Superior Indebtedness
may have been issued, as their respective interests may appear, for application
to the payment of all Superior Indebtedness remaining unpaid to the extent
necessary to pay all Superior Indebtedness in full in money or money's worth in
accordance with its terms, after giving effect to any noncurrent payment or
distribution to or for the holders of such Superior Indebtedness.

      Upon any payment or distribution of assets of the Company referred to in
this ARTICLE VIII, the Holder shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which any dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent
or other Person making such payment or distribution, delivered to the Holder,
for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of the Superior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this ARTICLE VIII.
<PAGE>

      For purposes of this ARTICLE VIII, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized, or securities of the Company or any other corporation provided for
by a plan of reorganization, the payment of which is subordinated at least to
the extent provided in this ARTICLE VIII with respect to this Debenture to the
payment of all Superior Indebtedness which may at the time be outstanding;
PROVIDED that (i) Superior Indebtedness is assumed by the new reorganization,
and (ii) the rights of the holders of the Superior Indebtedness are not, without
the consent of such holders, altered by such reorganization. The consolidation
of the Company with, or into another corporation or the liquidation or
dissolution of the Company following the conveyance, lease or transfer of its
property as an entirety, or substantially as an entirety, to another corporation
upon the terms and conditions provided in ARTICLE VII hereof shall not be deemed
a dissolution, winding-up, liquidation or reorganization for the purposes of
this SECTION 8.2 if such other corporation or Person shall, as a part of such
consolidation, merger, conveyance, lease or transfer, comply with the conditions
stated in ARTICLE VII hereof.

      Nothing contained in this ARTICLE VIII or elsewhere in this Debenture is
intended to or shall impair, as between the Company, its creditors other than
the holders of Superior Indebtedness, and the Holder, the obligation of the
Company, which is absolute and unconditional, to pay to the Holder the principal
of and interest on this Debenture as and when the same shall become due and
payable in accordance with its terms, or is intended to or shall affect the
relative rights of the Holder and creditors of the Company other than the
holders of the Superior Indebtedness, nor shall anything herein prevent the
Holder from exercising all remedies otherwise permitted by applicable law upon
default, subject to the rights, if any, under this ARTICLE VIII of the holders
of Superior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.

      If the Company fails because of this ARTICLE VIII to pay principal of or
interest on this Debenture on the due date, the failure is still an Event of
Default.

SECTION 8.3 INTENTIONALLY OMITTED

SECTION 8.4 HOLDER'S RELATION TO SUPERIOR INDEBTEDNESS

      The Holder shall be entitled to all the rights set forth in this ARTICLE
VIII in respect of any Superior Indebtedness at any time held by it, to the same
extent as any other holder of Superior Indebtedness, and nothing herein shall
deprive the Holder of any of its rights.

      With respect to the holders of Superior Indebtedness, the Holder
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this ARTICLE VIII, and no implied covenants or
obligations with respect to the holders of Superior Indebtedness shall be read
into this Debenture against the Holder. The Holder shall not be deemed to owe
any fiduciary duty to the holders of Superior Indebtedness.

SECTION 8.5 NO IMPAIRMENT OF SUBORDINATION

      No right of any present or future holder of any prior Superior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by


<PAGE>

any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Debenture, regardless of any knowledge thereof
which any such holder may have or otherwise be charged with.

                                   ARTICLE IX

                             CONVERSION OF DEBENTURE

SECTION 9.1 CONVERSION PRIVILEGE

      The Holder shall have the right at its option, at any time during usual
business hours on or before the close of business on or prior to February 7,
2005 (except that, with respect to this Debenture which shall be called for
redemption, such right shall terminate at the close of business on the fifth
Business Day next preceding the Redemption Date of this Debenture, unless the
Company shall default in payment due upon redemption thereof) to convert,
subject to and in compliance with the terms and provisions of this ARTICLE IX,
the principal of this Debenture or any portion of the principal amount thereof
into shares of Common Stock of the Company at a conversion price equal to $3.00
aggregate principal amount of this Debenture for each share of Common Stock or,
in case an adjustment of such price has taken place pursuant to the provisions
of this ARTICLE IX, then at the price as last adjusted (referred to herein as
the "conversion price"), upon surrender of this Debenture to the Company at its
office in Overland Park, Kansas with the form of conversion notice included
herewith as EXHIBIT B executed by the Holder (hereinafter referred to as the
"conversion notice") evidencing the Holder's intention to convert this Debenture
or a specified portion (as above provided) hereof, specifying the name in which
the shares of Common Stock deliverable upon such conversion shall be registered,
with the address of the Person (and taxpayer identification numbers, if
applicable) so named, and, if so required by the Company accompanied by a
written instrument or instruments of transfer in form satisfactory to the
Company duly executed by the Holder or his attorney duly authorized in writing.
For convenience, the conversion of the principal of this Debenture into Common
Stock is herein sometimes referred to as the "conversion" of this Debenture.
Notwithstanding anything to the contrary, the Holder shall not be entitled to
make a partial conversion of this Debenture unless such partial conversion
results in the issuance of no less than 10,000 shares of Common Stock of the
Company by the Holder.

SECTION 9.2 EXERCISE OF CONVERSION PRIVILEGE

      As promptly as practicable after the surrender, as herein provided, of
this Debenture for conversion and the receipt of the conversion notice, as
herein provided, relating thereto, and, if applicable, the payment of the funds
provided for in SECTION 9.10 hereof, the Company shall deliver or cause to be
delivered at said office or agency, to or upon the written order of the Holder
of this Debenture so surrendered, a certificate representing the number of
fully-paid and non-assessable shares of Common Stock into which this Debenture
may be converted in accordance with the provisions of this ARTICLE IX,
registered in such name as is specified in the conversion notice, together with
any cash payable in respect of a fractional share. In case the Debenture shall
be surrendered for partial conversion, the Company shall execute and deliver to
or upon the written order of the Holder, without charge to the Holder (subject
to the provisions of SECTION 9.10 hereof), a new Debenture in an aggregate
principal amount equal to the unconverted

<PAGE>

portion of the surrendered Debenture. Subject to the following provisions of
this paragraph, such conversion shall be deemed to have been effected at the
close of business on the date when this Debenture shall have been surrendered
for conversion together with the conversion notice and any funds required by
SECTION 9.10 hereof (whichever shall last occur; the date of the last of such
events to occur is sometimes referred to hereinafter as the "Conversion Date"),
so that the rights of the Holder as such Holder shall cease at such time and the
Person entitled to receive the shares of Common Stock upon conversion of this
Debenture shall be treated for all purposes as having become the record holder
of such shares of Common Stock at such time and such conversion shall be at the
conversion price in effect at such time; PROVIDED, HOWEVER, that no such
surrender on any date when the stock transfer books of the Company shall be
closed shall be effective to constitute the Person entitled to receive the
shares of Common Stock upon such conversion as the record holder of such shares
of Common Stock of such date, but such surrender shall be effective to
constitute the Person entitled to receive such shares of Common Stock as the
record holder thereof for all purposes at the opening of business on the next
succeeding Business Day on which such stock transfer books are open.

      If the last day for the exercise of the conversion right at the place of
surrender shall not be a Business Day, then the last day for the exercise of
such right at such place shall be the next succeeding Business Day.

SECTION 9.3 NO CONVERSION ADJUSTMENTS

      No payment or adjustment shall be made upon any conversion in respect of
any dividends on the Common Stock delivered upon conversion which were declared
for payment to holders of Common Stock of record as of a date prior to the
Conversion Date.

SECTION 9.4 ADJUSTMENT OF CONVERSION PRICE

      The conversion price shall be subject to adjustment as follows:

      (a) In case the Company shall (i) pay a dividend in shares of its capital
stock, (ii) subdivide its outstanding shares of Common Stock, (iii) combine its
outstanding shares of Common Stock into a smaller number of shares, or (iv)
issue by reclassification of its shares of Common Stock any shares of the
Company, the conversion price in effect immediately prior thereto shall be
adjusted so that the holder of this Debenture thereafter surrendered for
conversion shall be entitled to receive the number of shares of the Company
which he would have owned or have been entitled to receive after the happening
of any of the events described above, had this Debenture been converted
immediately prior to the happening of such event. An adjustment made pursuant to
this subsection (a) shall become effective immediately after the record date in
the case of a dividend and shall become effective immediately after the
effective date in the case of a subdivision, combination or reclassification.

      (b) In case the Company shall issue Additional Shares of Common Stock at a
price per share of Common Stock less than the current conversion price in effect
on the date of and immediately prior to such issue, then, and in such event, the
price per share at which this Debenture may thereafter be converted into Common
Stock shall be determined by dividing the price per share for which this
Debenture was theretofore convertible into Common Stock by a

<PAGE>

fraction of which the numerator shall be the number of shares of Common Stock
outstanding on the date of issuance of such Additional Shares of Common Stock
plus the number of Additional Shares of Common Stock offered for subscription or
purchase, and of which the denominator shall be the number of shares of Common
Stock outstanding on the date of issuance of such Additional Shares of Common
Stock plus the number of shares which the aggregate offering consideration of
the total number of Additional Shares of Common Stock so offered would purchase
at such current conversion price. Such adjustments shall be made whenever such
Additional Shares of Common Stock are issued. For the purpose of this subsection
(b), the term "Additional Shares of Common Stock" shall mean all shares of
Common Stock, plus rights, options or warrants to subscribe for, purchase or
otherwise acquire shares of Common Stock, or securities convertible or
exchangeable into shares of Common Stock; provided, however, that such term
shall not mean stock awards, rights, options or warrants granted to directors,
management or employees of the Company pursuant to any director, management or
employee plans approved by the Board of Directors of the Company.

      (c) In case the Company shall distribute to all holders of its Common
Stock evidences of its indebtedness or assets (excluding cash dividends or other
cash distributions to the extent permitted by SECTION 5.6 hereof) or rights or
warrants to subscribe (excluding those referred to in subsection (b) above other
than pursuant to a shareholder's rights plan) for shares of Common Stock, then
in each such case the price per share at which this Debenture may thereafter be
converted into Common Stock shall be determined by dividing the price per share
for which this Debenture was theretofore convertible into Common Stock by a
fraction, of which the numerator shall be the current market price per share of
Common Stock (as defined in subsection (d) below) on the date of such
distribution and of which the denominator shall be such current market price per
share of the Common Stock, less the then fair market value (as determined by the
Board of Directors of the Company, whose determination shall be conclusive, and
described in a statement provided to the Holder of this Debenture) of the
portion of the assets or evidences of indebtedness so distributed or of such
subscription rights or warrants applicable to one share of the Common Stock.
Such adjustment shall be made whenever any such distribution is made and shall
become effective retroactively immediately after the record date for the
determination of stockholders entitled to receive such distribution.

      (d) For the purpose of any computation under subsection (c) above, the
current market price per share of Common Stock at any date shall be deemed to be
the average of the daily Closing Prices for the 30 consecutive Trading Days
commencing 45 Trading Days before the day in question.

      (e) For the purposes of this ARTICLE IX, any change solely in the par
value of the Common Stock or from par value to no par value or from no par value
to par value of such stock, shall not be deemed to be a reclassification or
recapitalization.

SECTION 9.5 FRACTIONS OF SHARES

      No fractional shares or script representing fractional shares shall be
issued upon the conversion of this Debenture. If any fractional interest in a
share of Common Stock would, except for the provisions of this SECTION 9.5, be
deliverable upon the conversion of this Debenture, the Company shall, in lieu of
delivering a fractional share therefor, adjust such

<PAGE>

fractional interest by paying the Holder an amount in cash equal (computed to
the nearest cent) to the Closing Price of such fractional interest on the
Trading Day next preceding the date of conversion.

SECTION 9.6 EFFECT OF MERGERS, ETC., ON CONVERSION PRIVILEGE

      In case of any capital reorganization, or of any reclassification of the
Common Stock (other than a reclassification covered by SECTION 9.4(a)(iv)), of
the Company or in case of the merger of the Company into any other corporation,
or of any transfer of the type described in SECTION 7.1(C) of the properties and
assets of the Company as, or substantially as, an entirety to any other
corporation, there shall be no adjustment of the conversion price pursuant to
SECTION 9.4 hereof, but this Debenture shall, after such capital reorganization,
reclassification of Common Stock, merger or transfer, be convertible into the
kind and amount of shares of stock or other securities or property (including
cash) to which the holder of the number of shares of Common Stock deliverable
(immediately prior to the time of such capital reorganization, reclassification
of Common Stock, merger or transfer) upon conversion of this Debenture would
have been entitled upon such capital reorganization, reclassification of Common
Stock, merger, or transfer; and in any case, if necessary, appropriate
adjustment shall be made in the application of the provisions set forth in this
ARTICLE IX with respect to the rights and interests thereafter of the Holder of
this Debenture, to the end that the provisions set forth in this ARTICLE IX
shall thereafter correspondingly be made applicable, as nearly as may reasonably
be, in relation to any shares of stock or other securities or property
(including cash) thereafter deliverable on the conversion of this Debenture. Any
such adjustment shall be confirmed as being accurately determined in accordance
with this SECTION 9.6 by a certificate of a firm of Independent public
accountants; and any adjustment so approved shall for all purposes hereof
conclusively be deemed to be an appropriate adjustment.

      The above provisions of this SECTION 9.6 shall similarly apply to
successive reorganizations, reclassifications, mergers, or transfers.

SECTION 9.7 NOTICE OF ADJUSTMENTS

      Whenever the conversion price is adjusted as herein provided, the Company
shall promptly provide the Holder a certificate of a firm of Independent public
accountants with respect thereto setting forth the conversion price after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment and the effective date thereof.

      The Company shall also forthwith cause to be mailed to the Holder a notice
stating that the conversion price has been adjusted and setting forth the
adjusted conversion price.

SECTION 9.8 NOTICE OF CERTAIN EVENTS

      In case:

            (1) the Company shall declare a dividend payable, or shall make any
      other distribution of its Common Stock (excluding cash dividends or other
      cash distributions to the extent permitted by SECTION 5.6 hereof); or
<PAGE>

            (2) the Company shall authorize the granting to all the holders of
      its Common Stock of rights or warrants to subscribe for or purchase any
      shares of stock of any class or of any other rights or warrants; or

            (3) of any capital reorganization or reclassification of the Common
      Stock of the Company (other than a subdivision or combination or change in
      the par value of its outstanding Common Stock), or of any merger to which
      the Company is a party and for which approval of any stockholders of the
      Company is required, or of any transfer described in SECTION 7.1(C) of all
      or substantially all of the assets of the Company, in the event any such
      merger or transfer will result in a change in the shares held by the
      holders of Common Stock; or

            (4) of the voluntary or involuntary dissolution, liquidation or
      winding-up of the Company;

then the Company shall cause to be mailed to the Holder, as promptly as
practicable but in any event at least 10 days prior to the applicable record
date, entitlement date or effective date hereinafter specified, a notice stating
(x) the date on which a record is to be taken for the purpose of such dividend,
distribution or granting of rights (the "record date"), or, if a record is not
to be taken, the date or anticipated date as of which the holders of Common
Stock of record to be entitled to such dividend, distribution or granting of
rights are to be determined (the "entitlement date"), or (y) the date or
anticipated date on which such capital reorganization, reclassification, merger,
transfer, dissolution, liquidation or winding-up is expected to become effective
(the "effective date"), and which notice, in the case of the notice specified in
clause (y), shall also state the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities or other property deliverable upon such capital
reorganization, reclassification, merger, transfer, dissolution, liquidation or
winding-up.

SECTION 9.9 COMPANY TO RESERVE COMMON STOCK; LISTING

      The Company covenants that it will at all times reserve and keep
available, free from pre-emptive rights, out of the aggregate of its authorized
but unissued Common Stock or its issued Common Stock held in its treasury, or
both, for the purpose of effecting conversions of this Debenture, the full
number of shares of Common Stock then deliverable upon the conversion of this
Debenture; and if at any time the number of authorized but unissued shares of
Common Stock shall not be sufficient to effect the conversion of this Debenture,
the Company will take such corporate action as may in the opinion of its counsel
be necessary to increase its authorized but unissued Common Stock to such number
of shares as shall be sufficient for that purpose.

      Before taking any action which would cause an adjustment reducing the
conversion price below the then par value (if any) of the shares of Common Stock
issuable upon conversion of this Debenture, the Company will take any corporate
action which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue fully paid and nonassessable shares of
such Common Stock at such adjusted conversion price.

      The Company covenants that if any shares of Common Stock reserved for
conversion of this Debenture require listing upon any national securities
exchange before such shares may be

<PAGE>

delivered upon conversion, the Company will in good faith, and as expeditiously
as possible, endeavor to cause such shares to be duly listed.

SECTION 9.10      TAXES ON CONVERSIONS

      The Company will pay any and all documentary, stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of shares of Common
Stock on conversion of this Debenture pursuant hereto; PROVIDED, HOWEVER, that
the Company shall not be required to pay any tax which may be payable in respect
of any registration of transfer involved in the issue or delivery of Common
Stock in a name other than that of the Holder of this Debenture to be converted,
and no such issue or delivery shall be made unless and until the Person
requesting such issue has paid to the Company the amount of any such tax or has
established, to the satisfaction of the Company, that such tax has been paid.

                                   ARTICLE X

                                  MISCELLANEOUS

permitted assigns, as the case may be.

      Whenever possible, each provision of this Debenture shall be interpreted
in such manner as to be effective and valid under applicable law, but if any
provision of this Debenture shall be held to be prohibited by or invalid under
applicable law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Debenture.

Debenture at a particular conversion price or rate) shall not be a Business Day,

                                                WARRANT TO PURCHASE 45,635
                                                SHARES OF COMMON STOCK

      FOR VALUE RECEIVED, AIRPORT SYSTEMS INTERNATIONAL, INC. (the "Company"), a
Kansas corporation, hereby certifies that KCEP VENTURES II, L.P., or any
permitted transferee of this Warrant (the "Holder"), is entitled to purchase
from the Company, at any one time in whole, or from time to time in part, during
the seven-year period commencing February 7, 2000 and ending at 5:00 p.m.,
Kansas City time, on February 7, 2007, forty-five thousand six hundred
thirty-five (45,635) fully paid and nonassessable shares of the authorized but
presently unissued common stock, $.01 par value, of the Company ("Common Stock")
at a purchase price of $3.30 per share; PROVIDED, HOWEVER, that the number of
shares of Common Stock to be delivered upon any exercise of this Warrant and the
purchase price to be paid for each such share, shall be subject to adjustment
from time to time as hereinafter set forth; and, PROVIDED FURTHER, that the
Purchaser shall not make any partial purchase of Warrant Shares unless the total
number of Warrant Shares to be purchased in such partial purchase shall be equal
to or greater than 10,000. The Company covenants and agrees that it will pay
when due any and all taxes which may be payable in connection with the issuance
of this Warrant, or the issuance of any Warrant Shares upon the exercise of this
Warrant; but the Company shall not be required to pay any tax in respect to any
subsequent transfer of this Warrant or the Warrant Shares. The shares of Common
Stock issuable and issued upon such exercise, as so adjusted from time to time,
together with all shares of Common Stock issuable and issued pursuant to other
Warrants which may be issued upon transfer or partial exercise of this Warrant,
are hereinafter referred to

<PAGE>

as the "Warrant Shares" and the purchase price, as adjusted, for each Warrant
Share which is in effect from time to time is hereinafter referred to as the
"Warrant Price."

      1. EXERCISE OF WARRANT.

      1.1 EXERCISE OF WARRANT. The Holder may exercise this Warrant, as a whole
at any one time or in part from time to time during the seven-year period
commencing February 7, 2000 and ending at 5:00 p.m., Kansas City time, on
February 7, 2007, by the surrender of this Warrant, together with the Notice of
Exercise attached hereto duly executed and specifying therein the number of
Warrant Shares to be purchased upon such exercise (which number shall be equal
to or greater than 10,000) and the Warrant Price then in effect and containing
the requisite information required to be furnished therein, at the then
principal executive office of the Company, accompanied by payment, in the manner
set forth below, equal to the Warrant Price in effect at the date of such
exercise multiplied by the total number of Warrant Shares to be purchased upon
such exercise. Payment for Warrant Shares purchased upon any such exercise shall
be made by wire transfer payable in available funds to the order of the Company.
If any such exercise is for less than all of the Warrant Shares then issuable
under this Warrant, such exercise shall be for a number of whole Warrant Shares
and the Company at its expense promptly shall issue and deliver to the Holder a
new Warrant covering on the face thereof the number of Warrant Shares in respect
of which this Warrant is not then exercised. Upon receipt by the Company of this
Warrant at the office or agency of the Company, along with payment and the
Notice of Exercise, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of the Company shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
the Holder.

      1.2 COMPANY TO REAFFIRM OBLIGATIONS. The Company, at the time of each
exercise of this Warrant, upon the request of the Holder, will acknowledge in
writing its continuing obligation to afford to the Holder any rights (including,
without obligation, any right to registration or qualification of the Warrant
Shares or other securities, if any, issued upon such exercise) to which the
Holder shall continue to be entitled after such exercise pursuant to the
provisions hereof; PROVIDED that if the Holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to the Holder any such rights.

      2. DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. As soon as
practicable (and in no event later than 10 days) after each exercise and
surrender of this Warrant, the Company, at its expense (including the payment by
it of any applicable issue taxes), will cause to be issued and delivered to the
Holder a certificate or certificates, registered in the name of the Holder, for
the number of fully paid and nonassessable Warrant Shares to which the Holder
shall be entitled upon such exercise, plus, in lieu of any fractional Warrant
Shares to which the Holder would otherwise be entitled, cash in an amount equal
to the fair value of such fractional Warrant Shares as of the date of exercise
determined as follows:

            (a) If the Common Stock is listed on a national securities exchange
      or admitted to unlisted trading privileges on such exchange, or quoted on
      the Nasdaq National Market ("Nasdaq") the current value shall be the last
      reported sale price of the Common Stock on such exchange or market on the
      last business day prior to the date of

<PAGE>

      exercise of this Warrant or if no such sale is made on such day, the
      average closing bid and asked prices for such day on such exchange or
      market; or

            (b) If the Common Stock is not so listed or admitted to unlisted
      trading privileges, the current value shall be the mean of the last
      reported bid and asked prices reported by the Nasdaq (or, if not so quoted
      on Nasdaq, by the National Quotation Bureau, Inc.) on the last business
      day prior to the date of the exercise of this Warrant; or

            (c) If the Common Stock is not so listed or admitted to unlisted
      trading privileges and bid and asked prices are not so reported, the
      current value shall be an amount, not less than book value, determined in
      such reasonable manner as may be prescribed by the Board of Directors of
      the Company, such determination to be final and binding on the Holder.

Together with the Certificates for the Warrant Shares, the Company shall also
deliver any other stock or other securities (collectively, "Other Securities")
and property (including cash, where applicable) to which such Holder may be
entitled upon such exercise pursuant to the provisions hereof.

      3. AUTHORIZATION AND RESERVATION OF WARRANT SHARES. The Company represents
and warrants to the Holder that (a) it has all requisite corporate power and
authority, and has taken all necessary corporate action, to issue and deliver
this Warrant, to authorize and reserve for issuance and, upon payment of the
Warrant Price therefor, to issue and deliver the Warrant Shares, and (b) the
execution and delivery of this Warrant and the consummation of the transactions
herein contemplated will not result in a breach or violation of, or constitute a
default or an event permitting acceleration of the rights of any third party
under, the Articles of Incorporation, as amended, or the Amended and Restated
Bylaws of the Company or any mortgage, lease, indenture, agreement, instrument,
statute, decree, order, judgment, rule or regulation to which the Company is
subject or a party. The Company agrees that, prior to the expiration of this
Warrant, the Company at all times will have authorized and in reserve, solely
for issuance and delivery upon the exercise of this Warrant, the total number of
Warrant Shares as from time to time may be issuable upon exercise of this
Warrant, and shall keep such Warrant Shares, as well as any and all Other
Securities and property as from time to time shall be deliverable to the Holder
upon the exercise of this Warrant, available for delivery to the Holder, free
and clear of all restrictions on, and preemptive rights with respect to, such
issuance and delivery.

      4. REORGANIZATION, CONSOLIDATION, MERGER, ETC.

      4.1 GENERAL. If, at any time or from time to time when this Warrant
remains outstanding, the Company shall (a) effect a reorganization within the
meaning of Section 368 of the Internal Revenue Code of 1986, as amended, or (b)
merge into any other person, firm or entity or (c) transfer all or substantially
all of its property or assets to any other person, firm or entity under any plan
or arrangement contemplating the exchange of the Company's stock or assets for
stock and/or other property (including cash) with, in the circumstance described
in this Section 4.1(c), the view to distributing such stock and/or other
property (including cash) to the Company's stockholders upon the dissolution of
the Company within 24 months after the date of


<PAGE>

such transfer, then, and in each such case, the Holder of this Warrant, upon the
exercise hereof as provided in Section 1 at any time after the effective date of
such reorganization or merger, or the effective date of such transfer and
dissolution, as the case may be, shall be entitled to receive (and the Company
shall be required to deliver), in lieu of the Common Stock (or Other Securities)
issuable upon such exercise prior to such effective date, the stock and/or other
property (including cash) to which the Holder would have been entitled
immediately following such effective date if the Holder had so exercised this
Warrant immediately prior thereto (or on the record date with respect to said
transaction if such exercise on such date otherwise would have been a condition
to the receipt of such stock and/or other property).

      4.2 REPLACEMENT OF WARRANT. Upon any reorganization or merger or any
transfer and subsequent dissolution described in subsection 4.1 hereof, each
Warrant Share purchasable upon exercise of this Warrant shall be deemed
thereafter to have been replaced for the purposes hereof by the stock and/or
other property (including cash) issued or distributed in respect of one share of
Common Stock of the Company as a consequence of such reorganization, merger, or
such transfer and dissolution, as the case may be, and adequate provision to
effect such replacement shall be made at the time thereof, and notice of the
provision for such replacement so proposed to be made shall be mailed to the
Holder, together with the notice of such reorganization, merger or transfer and
dissolution as provided in Section 6 hereof.

      4.3 RECAPITALIZATION. If, at any time or from time to time when this
Warrant remains outstanding, the Company shall effect a recapitalization of such
character that the Warrant Shares shall be changed into or become exchangeable
for a larger or smaller number of shares of Common Stock, then thereafter the
number of Warrant Shares which the Holder shall be entitled to receive upon
exercise of this Warrant shall be increased or decreased, as the case may be, in
direct proportion to the increase or decrease in the number of shares of Common
Stock of the Company by reason of such recapitalization, and the Warrant Price
of such recapitalized Warrant Shares shall, in the case of an increase in the
number of shares of Common Stock of the Company, be proportionately reduced, and
in the case of a decrease in the number of shares of Common Stock of the
Company, be proportionately increased. An adjustment made pursuant to this
subsection 4.3 shall become effective as of the effective date of such
recapitalization.

      4.4 OTHER ADJUSTMENTS, WARRANT SHARES ADJUSTED. The Company, by action of
its Board of Directors, shall make such other equitable adjustments to the
Exercise Price as may be necessary to protect the Holder against dilution of
this Warrant, as contemplated in this Section 4.

      5. ADJUSTMENTS TO PREVENT DILUTION.

      5.1 ADJUSTMENTS FOR STOCK DIVIDENDS, ETC. If the Company shall pay a
dividend in shares of its Common Stock, subdivide (split) its outstanding shares
of Common Stock, combine (reverse split) its outstanding shares of Common Stock,
or issue by reclassification of its shares of Common Stock any shares or other
securities of the Company, the number of shares of Common Stock the Holder
hereof is entitled to purchase pursuant to this Warrant immediately prior
thereto shall be adjusted so that the Holder shall be entitled to receive upon
exercise that number of shares of Common Stock which he or she would have owned
or


<PAGE>

would have been entitled to receive after the happening of any of the events
described above had this Warrant been exercised immediately prior to the
happening of such event, and the Warrant Price per share shall be
correspondingly adjusted. An adjustment made pursuant to this subsection 5.1
shall become effective immediately after the record date in the case of the
stock dividend or other distribution and shall become effective immediately
after the effective date in the case of a subdivision, combination or
reclassification. The Holder of this Warrant shall be entitled to participate in
any subscription or other rights offering made to holders of shares of Common
Stock (other than an offering of rights pursuant to a shareholder rights plan or
similar plan protecting control of the Company) as if it had purchased the full
number of shares as to which this Warrant remains unexercised immediately prior
to the record date for such rights offering.

      5.2 ADJUSTMENT OF WARRANT PRICE UPON ISSUANCE OF ADDITIONAL SHARES OF
COMMON STOCK. In case the Company shall issue Additional Shares of Common Stock
at a price per share of Common Stock less than the Warrant Price in effect on
the date of and immediately prior to such issue, then, and in such event, the
Warrant Price per Warrant Share shall be determined by dividing the Warrant
Price per Warrant Share by a fraction of which the numerator shall be the number
of shares of Common Stock outstanding on the date of issuance of such Additional
Shares of Common Stock plus the number of Additional Shares of Common Stock
offered for subscription or purchase, and of which the denominator shall be the
number of shares of Common Stock outstanding on the date of issuance of such
Additional Shares of Common Stock plus the number of shares which the aggregate
offering consideration of the total number of Additional Shares of Common Stock
so offered would purchase at such Warrant Price. Such adjustments shall be made
whenever such Additional Shares of Common Stock are issued. For the purpose of
this subsection 5.2, the term "Additional Shares of Common Stock" shall mean all
shares of Common Stock, plus rights, options or warrants to subscribe for,
purchase or otherwise acquire shares of Common Stock, or securities convertible
or exchangeable into shares of Common Stock; provided, however, that such term
shall not mean stock awards, rights, options or warrants granted to directors,
management or employees of the Company pursuant to any director, management or
employee plans approved by the Board of Directors of the Company.

      5.3 LIMITATIONS ON ADJUSTMENTS. No adjustment shall be required pursuant
to the provisions of subsection 5.1 or 5.2 hereof unless such adjustment would
require a change of at least 1 % in the Warrant Price; PROVIDED, however, that
any adjustments which, pursuant to the provisions of this subsection 5.3, are
not required to be made shall be carried forward and taken into account in any
subsequent adjustment.

      5.4 CERTIFICATE AS TO ADJUSTMENTS. Whenever the Warrant Price and/or
number of Warrant Shares is adjusted as provided in this Warrant and upon any
modification of the rights of the Holder in accordance with the provisions of
this Warrant, the Company shall (a) promptly prepare a certificate, signed by
the Company's chief financial officer, setting forth the Warrant Price and the
number of Warrant Shares after such adjustment or the effect of such
modification, a brief statement of the facts requiring such adjustment or
modification and the manner of computing the same and (b) cause copies of such
certificate to be mailed (in accordance with Section 13 below) to the Holder of
this Warrant.


<PAGE>

      6. NOTICES OF RECORD DATE, ETC. In the event of:

            (a) any taking by the Company of a record of the holders of any
      class of securities for the purpose of determining the holders thereof who
      are entitled to receive any dividend (other than a cash dividend payable
      out of earned surplus of the Company) or other distribution, or any right
      to subscribe for, purchase or otherwise acquire any shares of stock of any
      class or any other securities or property, or to receive any other right,

            (b) any capital reorganization of the Company, any reclassification
      or recapitalization of the capital stock of the Company or any transfer of
      the type described in Section 4.1(c) of all or substantially all the
      assets of the Company to or merger of the Company into any other person,

            (c) any voluntary or involuntary dissolution, liquidation or
      winding-up of the Company, or

            (d) any proposed issue or grant by the Company of any shares of
      stock of any class or any other securities (other than in a transaction or
      pursuant to the exercise of a warrant, right or option which, pursuant to
      the provisions of Sections 4 or 5 hereof would not give rise to any
      adjustment of the Warrant Shares or Warrant Price), or any right or option
      (other than rights or options under any employee stock bonus, stock
      purchase or stock option plan) to subscribe for, purchase or otherwise
      acquire any shares of stock of any class or any other securities (other
      than the issuance of Warrant Shares or Other Securities upon the exercise
      of this Warrant),

then and in each such event the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, (ii)
the date on which any such reorganization, reclassification, recapitalization,
transfer, merger, dissolution, liquidation or winding-up is to take place, and
the time, if any, as of which the holders of record of Common Stock (or Other
Securities) shall be entitled to exchange their shares of Common Stock (or Other
Securities) for securities or other property deliverable upon such
reorganization, reclassification, recapitalization, transfer, merger,
dissolution, liquidation or winding-up, and (iii) the amount and character of
any stock or other securities, or rights or options with respect thereto,
proposed to be issued or granted, the date of such proposed issue or grant and
the persons or class of persons to whom such proposed issue or grant is to be
offered or made. Such notice shall be mailed at least 20 days prior to the date
therein specified.

      7. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its
Articles of Incorporation, as amended, or through any reorganization, transfer
of assets, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder against
such dilution or such other impairment. Without limiting the generality of the
foregoing, the Company


<PAGE>

(a) will not increase the par value of any shares of stock receivable upon the
exercise of this Warrant above the amount payable therefor upon such exercise,
(b) will take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
stock upon the exercise of this Warrant and (c) will not make a transfer of the
type described in Section 4.1(c) of all or substantially all of its properties
and assets to any other person (corporate or otherwise), or merge into any other
person or permit any such person to merge into the Company (if the Company is
not the surviving person), unless such other person shall expressly assume in
writing and will be bound by all the terms of this Warrant.

      8. TRANSFERABILITY OF WARRANTS.

      8.1 SECURITIES ACT OF 1933. This Warrant or the Warrant Shares or any
other security issued or issuable upon exercise of this Warrant may not be

amended, and then only against receipt of an agreement of such person to whom
such offer of sale is made to comply with the provisions of this subsection 8.1
with respect to any resale or other disposition of such securities.

certificate representing Warrant Shares or any other security issued or issuable
upon exercise of this Warrant not theretofore distributed to the public pursuant
to a registered offering or sold to underwriters for distribution to the public
pursuant to a registered offering, unless counsel for the Company is of the
opinion as to any such certificate that such legend is unnecessary:

            THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE
            SECURITIES LAWS OF ANY STATE. NO TRANSFER, SALE OR OTHER DISPOSITION
            OF THE SHARES MAY BE MADE UNLESS A REGISTRATION STATEMENT UNDER SAID
            ACT, AND SUCH REGISTRATION OR QUALIFICATION AS MAY BE NECESSARY
            UNDER THE SECURITIES LAWS OF ANY STATE, HAS BECOME EFFECTIVE, OR
            AIRPORT SYSTEMS INTERNATIONAL, INC. HAS BEEN FURNISHED WITH AN
            OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH
            REGISTRATION OR QUALIFICATION IS NOT REQUIRED WITH RESPECT TO SUCH
            PROPOSED DISPOSITION THEREOF AND THAT SUCH DISPOSITION WILL NOT
            CAUSE THE LOSS OF THE EXEMPTION UNDER THE SECURITIES LAW ON WHICH
            AIRPORT SYSTEMS INTERNATIONAL, INC. ORIGINALLY RELIED IN ISSUING OR
            SELLING THE SHARES TO THE ORIGINAL HOLDER THEREOF.

II, L.P., in the event of liquidation or dissolution of either such entity, or
(d) a purchaser, or officers of a purchaser, of substantially all of the assets
of Kansas City Equity Partners L.C., or KCEP Ventures II, L.P., and shall be so
transferable only upon the books of the Company which the Company shall cause to
be maintained for such purpose, provided however, any such transfer is in an
amount which permits the transferee to purchase a minimum of 10,000 Warrant
Shares, unless otherwise consented to by the Company. The Company may treat the
registered holder of this Warrant appearing on the Company's books at any time
as the Holder for all purposes.

      9. REGISTRATION RIGHTS. Pursuant to that certain Investor's Rights
Agreement, dated as of the date hereof, by and between the Company and KCEP
Ventures II, L.P., KCEP Ventures II, L.P. has received certain "demand" and
"piggy-back" registration rights with respect to the Warrant Shares.

Company of the loss, theft, destruction or mutilation of this Warrant, and of
indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver to the Holder a new Warrant of like date, tenor and
denomination.

      11. EXCHANGE LISTING. Prior to the issuance of any Warrant Shares, the
Company at its own expense, shall secure the listing of such shares upon any
securities exchange upon which shares of the Company's Common Stock are listed.

      12. WARRANT HOLDER NOT STOCKHOLDER. Except as otherwise provided herein,
this Warrant does not confer upon the Holder any right to vote or to consent or

matters whatsoever, or any other rights or liabilities as a stockholder, prior
to the exercise hereof.

      13. NOTICES AND COMMUNICATIONS. No notice or other communication under
this Warrant shall be effective unless, but any notice or other communication

made in Dollars, without set-off or counterclaim and free and clear of, and
without deduction for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions, withholdings or
restrictions or conditions of any nature whatsoever now or hereafter imposed,
levied, collected, withheld or assessed against the Borrowers (the "Taxes"). If
any Taxes are imposed and required to be withheld from any such payment, the
Borrowers shall either (i) increase the amount of such payment so that the Bank
will receive a net amount (determined by adding any additional amount payable by
the Borrowers hereunder and then subtracting the amount of all Taxes) equal to
the amount due hereunder, or (ii) pay such Taxes to the appropriate taxing
authority for the account of the Bank, and, as promptly as possible thereafter,
send the Bank an original receipt (or a copy thereof that has been stamped by
the appropriate taxing authority to certify payment) showing payment thereof,
together with such additional documentary evidence as the Bank may from time to
time reasonably require. If the Borrowers fail to perform their obligations to
the Bank under parts (i) or (ii) of the preceding sentence, the Borrowers shall
indemnify the Bank for any such Taxes that are paid by the Bank PLUS all
incremental Taxes, interest or penalties that may become payable as a
consequence of such failure.

      4.2 ILLEGALITY. Notwithstanding any other provision of this Agreement, in
the event that it shall become unlawful for the Bank to maintain any aspect of
its


                                       21
<PAGE>

Commitment as contemplated by this Agreement, the Commitment of the Bank to
extend the Loan or any Letter of Credit so affected shall be cancelled, and the
Borrowers agree to prepay to the Bank, within two (2) Business Days of receipt
of written demand by the Bank, all of the outstanding Borrowers' Obligations to
which that portion of the Commitment which is terminated as a result of
illegality relates. The Bank agrees that it will take such steps as may be
reasonably available to it to avoid or mitigate any illegality, provided that
the taking of such steps shall not in the opinion of the Bank be materially
prejudicial to it.

      4.3      INCREASED  COSTS.  In the event that any  change in  applicable
law, treaty,  regulation or directive, or in the interpretation or application
thereof,  or  compliance  by the Bank with any request  (whether or not having
the force of law) of any  relevant  central bank or other  comparable  agency,
shall

               (a) subject the Bank to any tax of any kind whatsoever (other
than taxes referred to in SECTION 4.1(B) hereof for which the Bank was
reimbursed by the Borrowers pursuant to the terms of that Section) with respect
to this Agreement or any of the other Financing Documents, any portion of the
Loan or the Letters of Credit or of the Borrowers' Obligations with respect
thereto, or any other transactions contemplated hereby or by the terms of any of
the other Financing Documents, or

               (b) change the basis of taxation of payments to the Bank of any
portion of the Borrowers' Obligations, fees, commissions or any other amount
payable under this Agreement or under the other Financing Documents (except for
changes in the rate of tax on the overall net income of the Bank), or

               (c) impose, modify or deem applicable any reserve, special
deposit or similar requirement against foreign assets held by, or deposits in or
for the account of, or advances or loans by, or acceptances created by, or any
other acquisition of funds by, any office of the Bank, which reserve, special
deposit or similar requirement is applied to assets such as the Loan or
Borrowers' Obligations or any portion thereof, or

               (d) increase the amount of capital required or expected to be
maintained by the Bank, or by any corporation controlling the Bank (a "Parent"),
or reduce the rate of return on capital earned by the Bank or any Parent, (as
determined by the Bank or any Parent taking into consideration their internal
policies with respect to capital adequacy and desired return on capital), which
increased capital or reduced rate of return on capital is applied to assets such
as the Loan or the Letters of Credit or Borrowers' Obligations or any portion
thereof, or

               (e) impose upon the Bank any other condition with respect to this
Agreement or the transactions contemplated hereby or by the other Financing
Documents, the result of which is to increase the actual cost to the Bank of
making the Loan or issuing the Letters of Credit under this Agreement or the
other Financing


                                       22
<PAGE>

Documents or to reduce any amount receivable by the Bank under this Agreement or
under the other Financing Documents or to increase the capital or reduce the
rate of return on capital which the Bank, or any Parent is required or expected
to maintain as a result of this Agreement, the other Financing Documents, the
Loan or the Letters of Credit, the Borrowers' Obligations, or any portion
thereof,

THEN the Borrowers shall pay to the Bank within thirty (30) days of a written
demand by the Bank, additional amounts which will compensate the Bank or any
Parent so affected, for such increased cost, reduced amount receivable,
increased capital or reduced return on capital, as the case may be. Each such
demand by the Bank shall be accompanied by a certificate setting forth in
reasonable detail (i) the change that gave rise to such increased cost, reduced
amount receivable, increased capital or reduced rate of return on capital, (ii)
the additional amounts payable pursuant to the foregoing sentence, and (iii) a
calculation of such amount, which certificate shall be conclusive absent
manifest error.

      Upon the occurrence of any of the foregoing events, the Borrowers shall
have the option, upon not less than five (5) Business Days' prior written notice
to the Bank, to prepay to the Bank all of the then outstanding Borrowers'
Obligations to which such increased costs relate and all other related sums due
by the Borrowers under the terms of this Agreement and the other Financing
Documents, in which event that portion of the Bank's Commitment so affected
shall immediately be cancelled. In the event that the Borrowers elect to prepay
the Borrowers' Obligations in accordance with the preceding sentence, all
provisions herein and in the other Financing Documents regarding prepayment
shall apply and the Borrowers will still be obligated to pay to the Bank the
additional amounts described by this SECTION 4.3 with respect to all periods in
which the affected Borrowers' Obligations remained outstanding.

      4.4 COMPUTATIONS. All computations of interest and fees payable pursuant
to the terms of this Agreement or any of the other Financing Documents shall be
made on the basis of a 360-day year applied to actual days elapsed.

      4.5 APPLICATION OF PAYMENTS. All payments (including prepayments) made by
the Borrowers in respect of the Borrowers' Obligations shall be applied by the
Bank FIRST to any unpaid costs, fees and expenses due under this Agreement and
the other Financing Documents, SECOND, to the payment of accrued and unpaid
interest, and FINALLY, to the payment of the principal amount of the Borrowers'
Obligations to which such payment pertains.

Notwithstanding any provision contained herein or in any of the other Financing
Documents, all Proceeds of the Export Receivables and Export Inventory which are
received by ASI or the Bank shall immediately be applied FIRST to the prepayment
of the Borrowers' Loan Obligations and THEN, in the event that any Default or
Event of Default has occurred and is continuing or would be caused by virtue of
the outstanding Borrowers' Obligations with respect to the Utilized Portion of
the Commitment


                                       23
<PAGE>

exceeding the Collateral Value, to the prepayment (by the deposit of cash
collateral) of the Borrowers' Letter of Credit Obligations, and all other
provisions regarding prepayment which are contained in this Agreement and in the
other Financing Documents shall apply.

      4.6 RELIANCE BY BANK ON COMMUNICATIONS AND AUTHORIZATIONS FROM BORROWER.
In making the Loan or in issuing any Letter of Credit pursuant to this Agreement
and the other Financing Documents, the Bank shall be authorized to rely on any
Borrowing Base Certificate, Application and Agreement for Commercial Letter of
Credit, Application and Agreement for Standby Letter of Credit, or other notice
or communication which appears to have been executed and delivered by any one or
more of the authorized officers of ASI who are designated in the certificate
delivered by ASI to the Bank in accordance with Section 7.1(d) hereof (each, an
"Authorized Borrowers' Representative"). In the event that the officer(s)
authorized to deliver such documents or to take action hereunder on behalf of
ASI become unavailable or unable to do so, the President of ASI shall appoint a
successor or successors and shall furnish the Bank with a certificate containing
the specimen signature of each officer so appointed to act on behalf of ASI
pursuant to this Agreement and the other Financing Documents.

      4.7 NATURE OF ALL BORROWERS' OBLIGATIONS; RIGHT OF CONTRIBUTION. Whether
or not expressly stated in this Agreement or in the other Financing Documents,
all of the Borrowers' Obligations shall constitute the joint and several
obligations of ASI and DCI.

      Each Borrower shall have a right of contribution to obtain reimbursement
from the other Borrower for any payment made by such Borrower in respect of the
Borrowers' Obligations, to the extent that such payment exceeds the benefit
realized by such Borrowers from the Loan and Letters of Credit.

      Any right of contribution between Borrowers which arises as a result of
payments made in respect of the Borrowers' Obligations under this Agreement or
any of the other Financing Documents shall be subordinate in all respects to the
Bank's right to receive payment in full of the Borrowers' Obligations.


                                    ARTICLE V
                                    SECURITY

      5.1      FINANCING  DOCUMENTS.  The  Borrowers'  Obligations to the Bank
in  respect  of the  Loan and the  Letters  of  Credit,  if  issued,  shall be
evidenced and secured by the Financing Documents.

      5.2 COLLATERAL. As security and collateral for the repayment of the
Borrowers' Obligations, each Borrower hereby grants to the Bank a lien on and
security interest in all of the Collateral.

                                       24
<PAGE>

      NOTWITHSTANDING THE FOREGOING GRANT BY EACH BORROWER OF A SECURITY
INTEREST IN ALL OF THE COLLATERAL, IT IS UNDERSTOOD AND AGREED BY THE PARTIES
HERETO THAT THE BANK SHALL HAVE AS SECURITY FOR THE BORROWERS' OBLIGATIONS (A) A
FIRST PRIORITY LIEN ON THE COLLATERAL WHICH IS COMPRISED OF EXPORT RECEIVABLES,
EXPORT INVENTORY AND ALL PROCEEDS THEREOF, INCLUDING ALL MONIES ON DEPOSIT FROM
TIME TO TIME IN THE BORROWERS' ACCOUNT AND (B) A SECOND AND SUBORDINATE LIEN ON
ALL OF THE OTHER COLLATERAL WHICH IS THE SUBJECT TO A FIRST PRIORITY LIEN IN
FAVOR OF THE BANK SECURING THE DOMESTIC FINANCING. THIS AGREEMENT AS TO LIEN
PRIORITY SHALL BE BINDING ON ANY SUCCESSORS AND ASSIGNS OF THE PARTIES,
INCLUDING (WITHOUT LIMITATION) EXIMBANK.

      The Borrowers further agree that the Bank shall have in respect of the
Collateral all of the rights and remedies of a secured party under the Uniform
Commercial Code of the State of Kansas and of all other states in which any
portion of the Collateral may be located, as well as those provided in this
Agreement.

      5.3 VALUATION OF COLLATERAL. For purposes of determining the amount of the
Available Commitment, from time to time, only eligible Export Receivables and
Export Inventory of ASI have a Collateral Value, as follows:

               (a) Export Receivables will be valued at 90% of their outstanding
principal amount from time to time, less the amount of any taxes, discounts,
credits, allowances and retainages; provided that each such Export Receivable
satisfies the following eligibility requirements; provided further, that to the
extent that any Export Receivable fails to satisfy each of the following
eligibility criteria with respect to only a portion of the aggregate amount of
payments due in respect of such Export Receivable, only that portion of the
aggregate amount of payments due which fails to satisfy each of the eligibility
criteria shall be deemed ineligible for purposes of this Agreement:

                      (i) the repayment obligation represented by the Export
      Receivable (A) is related to an export transaction between ASI and the
      Account Debtor and (B) either (i) is denominated in United States Dollars,
      or (ii) if denominated in a foreign currency, EXIMBANK has given specific
      approval for the Bank to attribute Collateral Value to such Receivable
      which is denominated in a specifically approved foreign currency, and the
      foreign exchange risk is 100% covered by a foreign exchange contract or
      other hedging mechanism whether provided by the Bank, another financial
      institution or reserved for internally and (C) is due and collectible
      within the United States; and

                      (ii) the Export Receivable arose in the ordinary course of
      business from the sale of goods or performance of services; unless
      specifically approved in writing by EXIMBANK, the Export-Receivable does
      not arise from a transaction which could be characterized as a
      bill-and-hold transaction, guaranteed sale, sale-and-return transaction,
      sale on approval, consignment or any other



                                       25
<PAGE>

      repurchase or return arrangement and all obligations of ASI which give
      rise to the right to receive payment of the Export Receivable (including,
      without limitation, shipment of Export Inventory) have been performed in
      full, an invoice has been remitted to the Account Debtor and the Account
      Debtor has accepted the subject goods or services, such that the Export
      Receivable represents a final sale and none of the subject Export
      Inventory has been in fact returned, rejected or repossessed; and

                      (iii) the payment obligation represented by the Export
      Receivable (A) has not been outstanding more than (I) sixty (60) calendar
      days past the original due date, or (II) ninety (90) calendar days past
      the original due date for any Export Receivable which is 100% insured
      through EXIMBANK or through an EXIMBANK-approved private insurer for
      comprehensive commercial and political risk, or the repayment of which is
      100% guaranteed by EXIMBANK, and (III) one hundred and eighty (180)
      calendar days past the original invoice date, (B) is not contingent or
      conditioned upon any event or subject to any claim of reduction,
      counterclaim, setoff, recoupment or other defense to payment, either as a
      result of returned, damaged, inferior or nonconforming Export Inventory or
      arising out of any other indebtedness of ASI to the Account Debtor, and
      (C) otherwise complies with any and all requirements of ASI's credit and
      collection policies; and

                      (iv) the payment obligation represented by the Export
      Receivable is not owed by an employee, stockholder of director of ASI, by
      a Subsidiary of ASI or any parent corporation or any other corporation
      affiliated with ASI by virtue of common ownership, partnership or joint
      venture arrangement; and

                      (v) ASI is sole owner of the Export Receivable and has not
      sold, disposed of, or otherwise encumbered its rights to receive payment
      under the Export Receivable, and the Export Receivable is not subject to
      the lien or security interest of any other Person except for Permitted
      Liens; and

                      (vi) the Export Receivable is included in the universe of
      Collateral with respect to which the Bank has filed a financing statement
      among all records required by the Uniform Commercial Code of the
      jurisdiction in which ASI maintains its principal place of business in
      order to properly perfect the Bank's security interest, and the Export
      Receivable is not evidenced by Chattel Paper (within the meaning of the
      Uniform Commercial Code); and

                      (vii) as provided in Section 7 of the applicable Loan
      Authorization Notice attached to the EXIMBANK Borrower Agreement, either
      (A) the payment obligation represented by the Export Receivable is owed to
      ASI by one of the Account Debtors whom the Bank has approved for open
      account


                                       26
<PAGE>

      terms and is within any maximum limits prescribed for open account terms
      with any such Account Debtor, all as set forth on SCHEDULE II attached
      hereto and made a part hereof, as the same may be supplemented or amended
      from time to time, and ASI has obtained the written acknowledgement from
      the Account Debtor that the Export Receivable has been assigned to the
      Bank and that all payments made with respect to the Export Receivable will
      be made directly to the Borrowers' Account; or (B) the entire amount of
      the payment obligation represented by the Export Receivable is secured by
      either (I) an irrevocable, United States dollar-denominated, commercial
      letter of credit issued or confirmed by a financial institution acceptable
      to the Bank, the proceeds of which letter of credit have been assigned to
      the Bank or which letter of credit shall specifically provide that payment
      thereunder shall be made solely to the Borrowers' Account, or (II) a
      Receivables insurance policy issued by EXIMBANK or a private insurance
      company acceptable to the Bank and EXIMBANK, in either case, the proceeds
      of which policy have been assigned to the Bank or (III) the Account Debtor
      has received "end user" financing from EXIMBANK for the payment
      obligations represented by the Export Receivable and the proceeds of
      EXIMBANK's loan to the Account Debtor are assigned to the Bank as security
      for the Borrowers' Obligations; and

                      (viii) the entire amount of the Export Receivable as
      reflected on ASI books and records and on any invoice or statement sent to
      the Account Debtor is due and owing to ASI, net of any finance charges or
      taxes relating thereto; no partial prepayment has been made with respect
      to the Export Receivable except as indicated; and the amount of the Export
      Receivable does not represent billings in excess of revenues earned on
      contracts in progress, unless such billings represent amounts due for work
      not yet performed but billed in accordance with the terms of ASI's
      contract with the applicable Account Debtor; and

                      (ix) the Export Receivable is not due from an Account
      Debtor which (A) has applied for, suffered or consented to the appointment
      of, or the taking of possession by, a receiver, custodian, trustee or
      liquidator of itself or all or a substantial portion of its property or

      case under any state or federal bankruptcy laws which are now or hereafter
      in effect, (E) has been adjudicated as bankrupt or insolvent, (F) has
      filed a petition seeking to take advantage of any other law providing for
      the relief of debtors, (G) has acquired to, or failed to have dismissed,
      any petition which is filed against it in any involuntary case brought
      under applicable bankruptcy law, or (H) has taken any action for the
      purpose of effecting any of the foregoing; and

                                       27
<PAGE>

                      (x) the payment obligation represented by the Export
      Receivable is not owed by a Person resident of any country which has been
      identified on EXIMBANK's Country Limitation Schedule as either (A) a
      country in which EXIMBANK is prohibited from doing business in the public
      or private sector (as appropriate), or (B) a country which is not
      available in the public or private sector (as appropriate) for EXIMBANK
      guaranteed financing due to commercial reasons, unless the payment
      obligation represented by the Export Receivable is secured by an
      irrevocable letter of credit issued or confirmed by a financial
      institution acceptable to EXIMBANK; and

                      (xi) the payment obligation represented by the Export
      Receivable does not result from the sale of Export Inventory for military
      defense purposes, and, except as specifically approved by EXIMBANK, the
      Account Debtor is not a military entity.

Notwithstanding compliance with the above-described eligibility requirements, no
Export Receivable which the Bank or EXIMBANK, in their reasonable judgment, deem
uncollectible for any reason shall have Collateral Value for purposes of
determining the amount of the Available Commitment from time to time.

               (b) Export Inventory will be valued at 75% of the lesser of its
wholesale cost or market value, from time to time, provided that each item of
Export Inventory, including work-in-process, satisfies the following eligibility
requirements and provided further that at no time shall the Collateral Value of
Export Inventory support more than 60% of the outstanding Loan Obligations plus
the aggregate stated amount of Commercial Letters of Credit:

                          (i)  the Export  Inventory is held by ASI for
      export sale and is located within the United States; and

                          (ii) the Export Inventory has been purchased,
      assembled or manufactured by ASI in the ordinary course of business, but
      not for speculative sale, and does not constitute demonstration Export
      Inventory or proprietary software (unless incorporated into or made part
      of a system), and is actually owned by, and in the possession of, ASI and
      not merely in the possession of ASI on a consignment or similar basis, and
      the Export Inventory has not been sold or disposed of by ASI and is not
      subject to the lien or security interest of any other Person except for
      Permitted Liens; and

                          (iii) the Export Inventory is not considered by ASI or
      other corporations which engage in substantially the same business as ASI
      to be damaged, defective, unmerchantable, slow moving or obsolete, and has
      not been returned by any other purchaser and is not defective, recalled or
      unfit for further


                                       28
<PAGE>

      processing and has not been previously sold or exported from the United
      States; and

                          (iv) the Export Inventory is located at an address
      which has been disclosed in Section 6.14 of this Agreement or by written
      supplement thereto delivered to the Bank and is included in the universe
      of Collateral with respect to which the Bank has filed a financing
      statement among all records required by the Uniform Commercial Code of the
      jurisdiction in which ASI maintains its principal place of business in
      order to properly perfect the Bank's security interest, and the Export
      Inventory is not evidenced by Chattel Paper (within the meaning of the
      Uniform Commercial Code) or any other documents of title; and

                          (v) the Export Inventory is not in the possession of a
      processor or bailee, or located on a premises leased or subleased to ASI
      or located on a premises subject to a mortgage in favor of a Person other
      than the Bank, unless the processor, bailee, lessor, sublessor or
      mortgagee (as the case may be) has executed and delivered all
      documentation reasonably required by the Bank to evidence the
      subordination or extinguishment of rights to the Collateral and to confirm
      the Bank's right to gain access to such premises to exercise any and all
      rights against the Collateral; and

                          (vi) the Export Inventory does not constitute and is
      not to be incorporated into any items which are destined for shipment to
      any country which has been identified on EXIMBANK's Country Limitation
      Schedule as either (A) a country in which EXIMBANK is prohibited from
      doing business in the public or private sector (as appropriate), or (B) a
      country which is not available in the public or private sector (as
      appropriate) for EXIMBANK-guaranteed financing due to commercial reasons,
      unless the purchase price of such item of Export Inventory to be sold
      within any such country is secured by an irrevocable letter of credit
      issued or confirmed by a financial institution acceptable to EXIMBANK; and

                          (vii) the    Export    Inventory    does   not
      constitute  defense  articles or defense services and is not destined to
      be purchased for military defense purposes; and

                          (viii) any Export Inventory which is listed on the
      United Munitions List (Art 121 of Title 22 of the Code of Federal
      Regulations), unless ASI shall have provided written notice to the Bank
      describing such items of Export Inventory and the corresponding invoice
      amount for each and EXIMBANK shall have approved such Export Inventory for
      financing under the Commitment; and

                                       29
<PAGE>

                          (ix)  the Export  Inventory  contains at least
      50% U.S. content,  which is defined to include all labor,  materials and
      services which are of United States origin or manufacture  and which are
      incorporated into an item within the United States; and

                          (x) the Export Inventory was not produced in violation
      of the Fair Labor Standards Act and it not subject to the "hot goods"
      provisions contained in 29 UJC ss.215 or any successor statute; AND

                          (xi)  the sale of the  Export  Inventory  will
      not result in an ineligible Receivable.

Upon the sale, shipment or other disposition of any item of Export Inventory,
such item of Export Inventory shall cease to have Collateral Value as Export
Inventory; however, the resulting Export Receivable shall have Collateral Value
provided that it otherwise satisfies all of the eligibility criteria for Export
Receivables described above.

      No Collateral other than Export Receivables and Export Inventory which
satisfy the eligibility requirements contained in paragraphs (a) and (b) above
shall have a value for purposes of determining the amount of the Available
Commitment from time to time. Any Export Receivable or Export Inventory which
subsequently fails to satisfy any of the eligibility requirements set forth in
this Section shall immediately cease to have any value for purposes of
determining the amount of the Available Commitment from time to time.

      For purposes of facilitating compliance by the Borrowers with the
foregoing eligibility requirements, a copy of EXIMBANK's current Country
Limitation Schedule is attached as Schedule I to this Agreement. This Schedule
is revised, amended and updated periodically, and the Bank will endeavor to
provide the Borrowers with copies of any supplements and modifications to the
Country Limitation Schedule which are provided to it by EXIMBANK.

      5.4 LOCATION OF COLLATERAL: PRINCIPAL PLACE OF BORROWERS' BUSINESSES: The
Borrowers agree to keep the Bank informed as to the location of the Collateral
and the address of each Borrower's principal place of business, give the Bank
prior notice of any contemplated changes of location or the address of either
Borrower's principal place of business, and not change the location of any of
the Collateral or the address of either Borrower's principal place of business,
without the prior written consent of the Bank. Notwithstanding the foregoing,
with notice to, but without the need for obtaining the consent of the Bank, the

Statements to properly perfect its lien in the Collateral.

      5.5 LOSS OF COLLATERAL. The Bank shall not be liable for any loss of any

      5.6      FILING  OF  FINANCING  STATEMENTS:   PERFECTION  OF  SECURITY
INTEREST IN COLLATERAL.

               (a) The security interest created by this Agreement shall be
perfected by the filing of financing statements which fully comply with Article
9 of the Uniform Commercial Code, as adopted by each of the states in which the
Collateral may be located, in such offices as may be required by the Bank. The
parties agree that:

                          (i) with respect to any such financing statement, a
      carbon, photographic or other reproduction of a security agreement or a
      financing statement is sufficient as a financing statement for purposes of
      Section 9-402 of the Uniform Commercial Code;

                          (ii) all necessary continuation statements shall be
      filed by the secured party or its assigns named therein within the time
      prescribed by Article 9 of the Uniform Commercial Code, as adopted by each
      of the states in which the Collateral may be located, in order to continue
      the perfection of the security interests created by this Agreement;

                          (iii) if at any time any of the information contained
      in any financing statement filed in connection with the security interests
      created by this Agreement, including without limitation, the location or
      description of the Collateral or the name, address or principal place of
      business of either Borrower, shall change in such manner as to cause such
      financing statement to become misleading in any material respect or as may
      impair the perfection of the security interests intended to be created by
      this Agreement, then the Borrowers shall promptly prepare an amendment to
      such financing statement as may be necessary to continue the perfection of
      the security interest intended to be created by this Agreement and file
      the same in any office where such amendment is required to be filed to
      continue the perfection of the security interests created by this
      Agreement;

                          (iv) upon the request of the Bank, the Borrowers shall
      prepare, have executed and file any amendments to the financing statements
      filed with respect to the security interests created by this Agreement in
      such form as the Bank may require; and

                          (v)         the  Borrowers  shall  bear all costs of
      any and all of the filings described in this SECTION 5.6,  including any
      recordation taxes payable as a result of such filings; and

                          (vi) upon request by the Bank or EXIMBANK, the
      Borrowers shall provide, at their expense, an opinion of counsel as to the

                                       31
<PAGE>

      effectiveness and perfection of the Bank's lien on the Collateral or any
      portion thereof.

               (b) To the extent deemed necessary or appropriate by the Bank,
the security interest created by this Agreement in any items of Collateral, for
which the UCC requires possession in order to perfect the Bank's lien in such
item of Collateral, shall be perfected by the delivery to the Bank or, with the
Bank's consent, to agents, branches, affiliates, correspondents or others acting
on behalf of the Bank, of all such Collateral as security for the Borrowers'
Obligations.

               (c) The security interest created by this Agreement in any
Receivable which is owed to either Borrower by any state or political
subdivision thereof or by the United States or any department, agency or
instrumentality thereof, shall be further perfected by such Borrower's execution
and delivery to the Bank of any instruments, the giving of any notices, and the
taking of any additional steps which may be required by the Federal Assignment
of Claims Act, the Federal Assignment of Contracts Act or any equivalent
provision of state or local law in order to ensure the effectiveness of the
assignment of such Receivable against the account debtor.

               (d) The security interest created by this Agreement in any
unsecured Export Receivable shall be further perfected by the execution and
delivery to the Bank of any instruments and the giving of any notices and the
taking of any additional steps which may be required under foreign law in order
to ensure the effectiveness of the assignment of such Export Receivable against
the Account Debtor.

               (a) The Borrowers shall require that each letter of credit issued
for its benefit with respect to any Export Receivable or Export Inventory shall
provide that one of the required documents for the first payment under the
letter of credit shall be a copy of an assignment of proceeds executed by such
Borrower as beneficiary of the letter of credit in favor of the Bank; said
assignment shall be for the full amount of the letter of credit, and shall
provide that all payments under the letter of credit shall be made directly to
the Borrowers' Account.

               (b) The Borrowers will take all necessary and advisable steps to
ensure that each letter of credit described in paragraph (a) above will either
(i) be delivered to the paying or confirming bank and that said paying or
confirming bank shall be authorized to retain the letter of credit on behalf of
the Bank as the assignee of the proceeds thereof, or (ii) be retained by such
Borrower, if no paying or confirming bank has been designated.

               (c) In order to perfect the Bank's assignment of the proceeds of
the letters of credit issued for such Borrower's benefit, each Borrower agrees
to act as the


                                       32
<PAGE>

agent of the Bank for the purposes of (i) accepting delivery of all such letters
of credit, and (ii) holding such letters of credit for the benefit of the Bank
until such time as the letters of credit are delivered to the paying or
confirming bank in accordance with paragraph (b) above.

               (d) In the event that either Borrower is unable to obtain the
assignment of the letter of credit in accordance with paragraph (a) above, such
Borrower shall be required to arrange in writing (with a copy to the Bank) with
the account party under any such letter of credit that the issuer of said letter
of credit include therein a provision to the effect that payment under said
letter of credit shall be negotiated only at the Bank's counters or,
alternatively, that payment shall be made only to the Borrowers' Account.

      5.8 ASSIGNMENT OF CONTRACT/PURCHASE ORDER PROCEEDS. The Borrowers shall
assign to the Bank, immediately after the execution of a contract of sale with
an importer or receipt of a purchase order from an importer, all amounts to be
paid to such Borrower under that contract or purchase order. Said assignment
shall provide that all of said payments shall be made directly to the Borrowers'
Account.

      5.9 ASSIGNMENT OF FOREIGN CREDIT INSURANCE POLICY PROCEEDS AND
BUYER/SUPPLIER FINANCING. The Borrowers shall, simultaneously with the execution
of this Agreement and as and when such policies are put into effect or financing
is obtained by either Borrower for the benefit of any Account Debtor, at any
time prior to the payment and performance in full of the Borrowers' Obligations,
assign to the Bank the proceeds of all foreign credit insurance policies
maintained by such Borrower and any financing obtained by such Borrower for the
benefit of any Account Debtor, including (without limitation) financing the
repayment of which is guaranteed by EXIMBANK, such assignment to provide for

other Financing Documents executed and delivered by the Borrower, and to incur
and perform the Borrowers' Obligations provided for herein and therein, all of

and by general equitable principles.

furnished by the Borrower in connection with the Financing Documents, contains
any untrue statement of a material fact or, when such financial statements,
Financing Documents, statements, reports and certificates are taken in their
entirety, omit to state a material fact necessary to make the statements
contained therein or herein not misleading as of the date hereof. There is no
fact known to the Borrower or which should be known to the Borrower which the
Borrower has not disclosed to the Bank in writing prior to the date of this
Agreement with respect to the transactions contemplated by the Financing
Documents, has, or in the future could, in the reasonable opinion of the
Borrower, have a Material Adverse Effect; provided, however, that no
representation is made as to the retrospective accuracy of any pro formas,
projections or forecasts (except that no information used as a basis for such
pro formas, projections or forecasts shall be knowingly or reasonably believed
by the Borrowers to be inaccurate when used).

and the violation of which would have a Material Adverse Effect, and the
Borrower has obtained any and all licenses, permits, franchises and other

any proceeding under any such law, or if corporate action shall be taken by
either of the Borrowers for the purposes of effecting any of the foregoing, or
(vi) by any act indicate its consent to, approval or acquiescence in any such
proceeding or the appointment of any receiver of or trustee for either of the
Borrowers or any substantial part of their properties, or suffers any such

               (i) EXECUTION; ATTACHMENT. Any execution or attachment shall be
levied against any of the Collateral, and such execution or attachment shall not

of record, 100% of the outstanding capital stock of DCI or such ownership shall
cease to vest in ASI voting control of DCI.

               (k) COLLATERAL VALUE EXCEEDED. Except for Permitted Overadvances,
the outstanding Borrowers' Obligations with respect to the Utilized Portion of
the Commitment shall at any time exceed the Collateral Value, and the Borrowers
shall fail to either reduce such outstanding Borrowers' Obligations or satisfy
the Bank that the Collateral Value should be increased within five (5) Business
Days, after written notice thereof shall have been given to the Borrowers by the
Bank.

               (l) LIENS AGAINST COLLATERAL. Any Lien in any of the Collateral
which is granted, or intended by the Financing Documents to be granted, to the
Bank ceases to be a valid, enforceable, perfected, first priority Lien, subject
only to Permitted Liens and a first priority Lien on the Overland Park Property

Mutual Service Life Insurance Company and a second priority Lien on the Olathe
Property (as defined in the documents relating to the Domestic Financing) in
favor of Johnson County Certified Development Company;

               (m)    ENFORCEABLE    FINANCING    DOCUMENTS.    Any   material
provisions  of  the  Financing  Documents  ceases  to be  valid,  binding  and
enforceable in accordance with its terms; OR
                                          --

               (n) EXIMBANK DOCUMENTS. Any Borrower fails to comply with any
provision of the EXIMBANK Borrower Agreement or the Loan Authorization Notice
attached thereto and such failure is not cured within thirty (30) calendar days.

      11.2 REMEDIES. NOTWITHSTANDING ANY PROVISION TO THE CONTRARY CONTAINED IN
THIS AGREEMENT, UPON THE OCCURRENCE OF A DEFAULT OR ANY EVENT OF DEFAULT OR UPON
RECEIPT BY THE BANK OF ANY NOTICE WHICH THE BORROWERS ARE REQUIRED TO GIVE UNDER
SECTION 8.9 OF THIS AGREEMENT, THE BANK MAY DISCONTINUE MAKING ADVANCES OF THE
LOAN AND ISSUING LETTERS OF CREDIT HEREUNDER IN ITS SOLE AND ABSOLUTE DISCRETION
AND WILL DISCONTINUE MAKING ADVANCES OF THE LOAN AND ISSUING LETTERS OF CREDIT
HEREUNDER IF AND TO THE EXTENT IT IS DIRECTED TO DO SO BY EXIMBANK.

      In addition, upon the occurrence of any Event of Default, and in every
such Event of Default and at any time thereafter, unless such Event of Default
shall be cured to the satisfaction of the Bank and EXIMBANK, the Bank may
exercise any one or more of the following remedies.

                                       52
<PAGE>

               (a) ACCELERATE     TERMINATION    DATE.    Accelerate    the
Termination  Date,   whereupon  the  Commitment  shall  terminate  as  of  the
accelerated Termination Date.

               (b) ACCELERATE THE BORROWERS' OBLIGATIONS. Demand immediate
payment in full of all of the Borrowers' Obligations under this Agreement and
the other Financing Documents, including (without limitation) all accrued and
unpaid interest thereon, whether or not (i) the Loan has become due and payable,
or (ii) the Commercial Letters of Credit or Standby Letters of Credit may remain
outstanding following repayment of the Borrowers' Obligations relating thereto,
whereupon all outstanding Borrowers' Obligations shall become immediately due
and payable without presentment, demand, protest, or any other notice of any
kind, all of which are hereby expressly waived, anything contained in this
Agreement or in the other Financing Documents to the contrary notwithstanding.

               (c) At any time after a Default or Event of Default, ("Blocked
Account Event"), upon written notice by the Bank to the Borrowers, the Borrowers
will cause all moneys, checks, notes, drafts and other payments relating to or
constituting proceeds of Receivables, or of any other Collateral, to be
forwarded to a Bank of America Blocked Depository Account (the "Blocked
Account"), in accordance with an account agreement relating thereto which the
Borrowers agree to execute, and in particular the Borrowers will (i) advise each
Account Debtor to address all remittances with respect to amounts payable on
account of any Receivables to such specified Blocked Account, and (ii) stamp all
invoices relating to any such amounts with a legend satisfactory to the Bank
indicating that payment is to be made to the Borrowers via the Blocked Account.
From and after the occurrence of a Blocked Account Event, the Bank may, in its
sole discretion, elect to continue the use of the Blocked Account
notwithstanding that the Default or Event of Default giving rise to the Blocked
Account Event was cured or otherwise waived.

               From and after such notice is given to the Borrowers that a
Blocked Account is required, the Borrowers and the Bank shall cause all
collected balances in the Blocked Account to be applied daily (i) on account of
the Borrowers' Obligations and the Borrowers' obligations in respect of the
Domestic Financing, consistent with the lien priorities on Export Receivables,
Export Inventory and the other Collateral in Section 5.2, such credits to be
entered on the first (1st) Business Day following receipt and to be conditioned
upon final payment in cash or solvent credits of the items giving rise to them,
and (ii) with respect to any balance remaining after such application, so long
as no Default or Event of Default has occurred and is continuing, for transfer
to the Borrowers' Account or such other account of the Borrowers as the
Borrowers and the Bank may agree.

               Any moneys, checks, notes, drafts or other payments referred to
in this Section which are received by or on behalf of the Borrowers will be held
in trust for the



                                       53
<PAGE>

Bank and will be delivered to the Bank as promptly as possible in the exact form
received, together with any necessary endorsements.

               Unless and until any such notice of a requirement of a Blocked
Account is given by the Bank, all Accounts Receivable may be collected directly
by the Borrowers, provided that such funds are deposited into a Bank of America
commercial account.

               (d) LIQUIDATION OF SECURITY INTEREST IN COLLATERAL. Upon the
occurrence of any Event of Default, and at any time during the continuance
thereof, the Bank shall have, in addition to all other rights and remedies, the
remedies of a secured party under the Uniform Commercial Code, or under any
other governing laws, including, without limitation, the right to take
possession of the Collateral (to which the Borrowers hereby specifically
consent), and for that purpose the Bank may, so far as the Borrowers can give
authority therefor, enter upon any premises on which the Collateral may be
situated and remove the same therefrom. Upon request of the Bank, the Borrowers
shall assemble and make the Collateral available to the Bank at a place to be
designated by the Bank. Unless the Collateral is perishable or threatens to
rapidly decline in value, or is of a type customarily sold on a recognized
market, the Bank shall give the Borrowers at least ten (10) calendar days' prior
notice of the time and place of any public sale or the time after which any
private sale or any other intended disposition is to be made. The Bank may at
any time in its discretion transfer any securities (I.E., stock or bonds) or
other property constituting the Collateral into its own name or that of its
nominee and receive the income thereon and hold the same as collateral for
Borrowers' Obligations or apply it to principal, or interest or other costs,
fees or charges due on, or with respect to, the Borrowers' Obligations. The
Borrowers hereby irrevocably constitute and appoint the Bank as the Borrowers'
true and lawful attorney in fact, with full power of substitution, at the sole
cost and expense of the Borrowers, but for the sole benefit of the Bank, to
convert the Collateral to cash, including without limitation, completing the
manufacturing process of work in process, and the sale (either public or
private) of all or any portion of the Collateral, to enforce collection of the
Collateral, either in its own name or in the name of the Borrowers, compromising
or settling with any Account Debtors and prosecuting, defending, compromising or
releasing any action relating to the Collateral; to receive, open and dispose of
all mail addressed to the Borrowers and to take therefrom any remittances on or
proceeds of the Collateral in which Bank has a security interest; to notify
United States Post Office authorities to change the address for delivery of mail
addressed to the Borrowers to such address as the Bank may designate; to indorse
the name of the Borrowers in favor of the Bank upon any and all checks, drafts,
money orders, notes, acceptances or other instruments of the same or different
nature; to sign and indorse the name of the Borrowers on and to receive as
secured party any of the Collateral, any invoices, schedules of collateral,
freight or express receipts and/or other documents of title of the same or
different nature relating to the Collateral; to sign the name of the Borrowers
on any notice to the Account Debtors or on verification of the Collateral; and
to sign and file or record on behalf of the Borrowers


                                       54
<PAGE>

any financing or continuation statements or other statements in order to
perfect, keep perfected or protect the Bank's security interest in the
Collateral. The Bank shall not be obliged to do any of the acts or exercise any
of the powers herein above authorized, but if the Bank elects to do any such act
or exercise any such power, it shall not be responsible to the Borrowers except
for the Bank's own willful misconduct or gross negligence. All powers conferred
upon the Bank by this Agreement, being coupled with an interest, shall be
irrevocable as long as any of the Borrowers' Obligations to the Bank shall
remain unpaid.

               (e)    BORROWERS  REMAINS LIABLE FOR DEFICIENCY.  The Borrowers
are  liable  for the  entire  amount of the  Borrowers'  Obligations  and will
remain  responsible  for any  deficiency  in any  proceeds  realized  upon any
liquidation of Collateral.

               (f) OTHER RIGHTS AND REMEDIES. In addition to any other rights or
remedies specifically set forth herein, the Bank shall have available to it all
rights and remedies under any of the Financing Documents and any other rights
and remedies afforded to it at law or in equity.

               (g) PERFORMANCE BY BANK. If the Borrowers shall fail to pay any
of the Borrowers' Obligations or the Borrowers shall otherwise fail to perform,
observe or comply with any of the conditions, covenants, terms, stipulations or
agreements contained in this Agreement or any of the other Financing Documents
and the same results in an Event of Default hereunder, the Bank, without notice
to or demand upon the Borrowers, and without waiving or releasing any of the
Borrowers' Obligations or any Event of Default, and in addition to any rights or
remedies available to it under any of the other Financing Documents, may (but
shall be under no obligation to) at any time thereafter make such payment or
perform such act for the account and at the expense of the Borrowers, and may,
to the extent permitted by law, enter upon the premises of the Borrowers for
that purpose and take all such action thereon as the Bank may consider necessary
or appropriate for such purpose. All sums so paid or advanced by the Bank and
all costs and expenses (including, without limitation, reasonable attorneys'
fees and expenses) incurred in connection therewith (the "Expense Payments")
together with interest thereon from the date of payment of the advance or the
date on which the expense was incurred until paid in full at the rate of three
percent (3%) per annum in excess of the Prime Rate shall be paid by the
Borrowers to the Bank on demand and shall constitute and become a part of the
Borrowers' Obligations.

               (h) NO CONDITIONS PRECEDENT TO EXERCISE OF REMEDIES. The
Borrowers shall not be relieved of any obligation by reason of the failure of
the Bank to comply with any request of the Borrowers or of any other person, to
sell any portion of the Collateral, or otherwise to enforce any provision of the
Financing Documents, or by reason of the release, regardless of consideration,
of all or any part of the Collateral, or other security for the Borrowers'
Obligations, or by reason of any agreement or stipulation between any subsequent
owner of the Collateral or other security for the


                                       55
<PAGE>

Borrowers' Obligations, or the Bank extending the time of payment or modifying
the terms of the Financing Documents without first having obtained the consent
of the Borrowers; and in the latter event, the Borrowers shall continue to be
liable to make payments according to the terms of any such extension or
modification agreement, unless expressly released and discharged in writing by
the Bank.

               (i) REMEDIES CUMULATIVE AND CONCURRENT. No remedy herein
conferred upon or reserved to the Bank is intended to be exclusive of any other
remedies provided for in the Financing Documents, and each and every such remedy
shall be cumulative, and shall be in addition to every other remedy given
hereunder, or under the Financing Documents, or now or hereafter existing at law
or in equity or by statute. Every right, power and remedy given by the Financing
Documents to the Bank shall be concurrent and may be pursued separately,
successively or together against the Borrower or the Collateral or other
security for the Borrowers' Obligations or any part thereof, and every right,
power and remedy given by the Financing Documents may be exercised from time to
time as often as may be deemed expedient by the Bank.

               (j) NO WAIVER. No delay or omission of the Bank to exercise any
right, power or remedy accruing upon the happening of an Event of Default shall
impair any such right, power or remedy or shall be construed to be a waiver of
any such Event of Default or any acquiescence therein. No delay or omission on
the part of the Bank to exercise any remedy hereunder, or acceptance by the Bank
of any partial payment on account of the Borrowers' Obligations shall constitute
a waiver of any such Event of Default and each of the remedies herein provided
shall remain continuously available to the Bank.

      12.2     SURVIVAL OF AGREEMENT; SUCCESSORS AND ASSIGNS; SUBSIDIARIES.

               (a) All covenants, agreements, representations and warranties
made herein and in the certificates delivered pursuant hereto shall survive the
making of the Loan and the issuance of any Letters of Credit, and the execution
and delivery to the Bank of this Agreement and all of the other Financing
Documents and shall continue in full force and effect until all of the
Borrowers' Obligations have been paid and performed in full.

               (b) Whenever in this Agreement any of the parties hereto is
referred to, such reference shall be deemed to include the successors and
assigns of such party; and all covenants, promises and agreements by or on
behalf of the Borrowers or any of their Subsidiaries which are contained in this
Agreement or in the other Financing Documents shall inure to the benefit of the
successors and assigns of the Bank, including (without limitation) EXIMBANK,
which is a third-party beneficiary of this Agreement and each of the other
Financing Documents to which it is not a direct party. The Bank may assign any
interest that it may have under this Agreement or the other Financing Documents
to any participant or to EXIMBANK, in each case without the prior consent of or
notice to the Borrowers or any other Person. The Borrowers may not assign any
interest that they may have under this Agreement or the other Financing
Documents, including (without limitation) the right to receive the benefit of
the Loan to be extended hereunder or the Letters of Credit to be issued
hereunder, without the prior written consent of the Bank and EXIMBANK. Any
assignment made or attempted by the Borrowers or either of them without the
prior written consent of the Bank and EXIMBANK shall be void and of no effect.
No consent by the Bank and EXIMBANK to an assignment by either Borrower shall
release such Borrower as the party primarily obligated and liable under the
terms of this Agreement unless the Borrower shall be released specifically by
the Bank and EXIMBANK in writing. No consent by the Bank


                                       58
<PAGE>

and EXIMBANK to an assignment shall be deemed to be a waiver of the requirement
of prior written consent by the Bank and EXIMBANK with respect to each and every
further assignment and as a condition precedent to the effectiveness of such
assignment.

      12.3     PAYMENT OF FEES AND EXPENSES.

               (a) LEGAL FEES AND EXPENSES. The Borrowers will pay all
out-of-pocket expenses incurred by the Bank in connection with (i) the
preparation and negotiation of this Agreement and the other Financing Documents,
(ii) the making of the Loan and the issuance of the Letters of Credit by the
Bank, (iii) the protection of the Collateral and any other security for the
repayment of the Borrowers' Obligations, and (iv) the enforcement and protection
of the rights of the Bank in connection with this Agreement or any of the other
Financing Documents, including, but not limited to, the fees and disbursements
of Miles & Stockbridge, Baltimore, Maryland, Bryan Cave LLP, Kansas City,
Missouri or other counsel employed by the Bank.

               (b) EXIMBANK FACILITY FEE. The Borrower shall be obligated to pay
directly to the Bank the EXIMBANK Facility Fee in the amount of U.S. $90,000 PER
ANNUM, to be prorated for any portion of a 12-month period during which the
Commitment will be outstanding, which is due and payable on the date of this
Agreement and on each anniversary of the date of this Agreement.

               (c) UNUSED LINE FEE. In connection with and as consideration for
the Bank's Commitment, the Borrowers shall pay a fee to the Bank, from the
Effective Date until the Termination Date, in an amount equal to one quarter of
one percent (.25%) PER ANNUM of the average daily unused portion of the
Commitment payable quarterly in arrears on the first day of each quarter and on
the date of any permanent reduction in the Commitment.

               (d) EARLY TERMINATION FEE. In the event that the Borrowers
terminate this Agreement at any time prior to the Termination Date, the
Borrowers shall pay to the Bank a prepayment fee of (a) two percent (2%) of the
Commitment if such termination occurs on or before the last day of the
eighteenth (18th) month after the Effective Date hereof, or (b) one percent (1%)
of the Commitment if the Termination Date has been extended and such termination
occurs before the new Termination Date but after the eighteenth month after the
Effective Date hereof.

               (e) PREPAYMENT FEE. Provided that no Event of Default has
occurred and is continuing or would occur as a result, upon the written request
of the Borrowers, the Bank will permit the Borrowers to permanently reduce the
Commitment ("Permanent Reductions") on the following conditions: (i) all
Permanent Reductions shall be in increments of not less than Two Hundred
Thousand and No/100 Dollars ($200,000); (ii) Permanent Reductions shall not
occur more than once in any thirty (30) day period; (iii) Permanent Reductions
shall not occur more than four (4) times during


                                       59
<PAGE>

the effectiveness of the Commitment; (iv) Lender shall be under no obligation to
re-lend any amount permanently reduced pursuant to a Permanent Reduction; (v) a
Permanent Reduction may not be made which would cause an overadvance against the
Borrowing Base after giving effect to such Permanent Reduction; (vi) a permanent
Reduction will be evidenced by an amendment to this Agreement, and will not be
effective until acknowledged by the Bank to the Borrowers in writing; (vii) a
Permanent Reduction would be supported by an equity investment into ASI in an
amount greater than or equal to the Permanent Reduction; (viii) the Borrowers
will pay the Permanent Reduction Prepayment Fee (as hereinafter defined) to the
Bank; and (ix) the Borrowers will pay the actual, reasonable costs of the Bank,
including without limitation legal fees and costs, incurred in connection with a
Permanent Reduction. The "Permanent Reduction Prepayment Fee" is equal to (a)
one and one-third percent (1.33%) of the amount of the Permanent Reduction if
such termination occurs on or before the last day of the eighteenth (18th)
months after the Effective Date hereof; or (b) two-thirds of one percent (.67%)
of the amount of the Permanent Reduction if the Termination Date has been
extended and such termination occurs before the new Termination Date but after
the eighteenth month after the Effective Date hereof.

      12.4 APPLICABLE LAW; JURISDICTION, CONSENT TO SERVICE OF PROCESS. This
Agreement and all of the other Financing Documents (except where expressly
indicated therein to the contrary) shall be construed in accordance with and
governed by the laws of the State of Missouri except as specifically provided
herein. The Bank and the Borrowers hereby submit to the non-exclusive
jurisdiction of any Missouri court or federal court sitting in Missouri over any
suit, action or proceeding arising out of or relating to this Agreement. Final
judgment in any such suit, action or proceeding brought in any such court shall
be conclusive and binding upon the Borrowers and may be enforced in any court to
the jurisdiction of which the Borrowers are subject, by a suit upon the
judgment.

      12.5 WAIVER OF TRIAL BY JURY. Each of the Borrowers and the Bank hereby
waive trial by jury in any action or proceeding to which the Borrowers (or
