                              EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (this "Agreement") is entered into as of the 6th day
of December, 1999, by and between Airport Systems International, Inc. (the
"Company") and Karl Gemperli, an individual ("Employee").

WHEREAS, the Company desires to employ Employee in the capacity described
herein and Employee desires to work for the Company in such capacity until such
time as the Company acquires all of the outstanding stock of DCI, Inc. ("DCI"),
at which time Employee shall become an employee of DCI.

NOW, THEREFORE, in consideration of the foregoing premises and of the mutual
covenants and agreements herein contained, Employee and the Company agree as
follows:

1.       Period of Employment. Subject to earlier termination as provided for
         in Section 6 hereof, the Company hereby employs Employee, and Employee
         hereby accepts such employment, for a period of one year, beginning on
         the date of this Agreement and continuing until the close of business
         on the first anniversary of the date of this Agreement.

2.       Duties of Employee. Until completion of the acquisition by the Company
         of DCI, Employee shall devote at least 20 hours per week to the
         business of the Company as directed by the President of the Company.
         Upon completion of the acquisition by the Company of DCI, Employee
         shall devote his full time and attention to the business of DCI in
         DCI's Kansas office. Employee shall then be employed as the President
         of DCI; and he shall perform such duties as shall be assigned to him
         by the Chief Executive Officer and Board of Directors of the Company
         (or DCI) and as are normally incident to such office. Employee shall
         comply with all policies and procedures of the Company and use his
         best efforts on behalf of the Company.

3.       Compensation. Prior to completion of the acquisition by the Company of
         DCI, the Company shall pay Employee a salary at the rate of $70,000
         per annum, payable in arrears in equal bi-weekly installments on every
         other Friday. After completion of such transaction, DCI shall pay
         Employee a salary at the rate of not less than $140,000 per annum. The
         Employee will receive an annual performance review. The Board of
         Directors of the Company shall annually review such performance review
         and salary and, based upon the performance of Employee and the
         financial results and condition of DCI and the Company, in its sole
         discretion, may increase (but not decrease) such salary. At the
         beginning of each fiscal year, a bonus plan shall be established by
         the Board of Directors based on DCI and Company performance goals. At
         the end of each fiscal year the Employee shall receive a bonus based
         upon performance against the established plan. In addition Employee
         shall be granted options to purchase 50,000 shares of the Company
         stock pursuant to the Company's qualified stock option plan. Such
         options shall vest in equal amounts over a five year period,
         commencing with the closing of the acquisition of DCI by the Company.
         The option price shall be based on the closing price of the Company's
         stock on the day this Agreement is signed.

4.       Benefit Plans. During the term of Employee's employment, Employee
         shall be entitled to participate in and receive the benefits of any
         retirement, insurance, hospitalization, health or similar plan
         currently in effect or hereafter adopted by the Company for the
         benefit of its key employees.

5.       Reimbursements. The Company shall reimburse Employee for reasonable
         travel and entertainment expenses incurred by him on behalf of the
         Company, subject to the limitations, approval, and substantiation
         requirements and other procedures from time to time established by the
         Company.

6.       Termination.

         (a)      Definitions.

                  (i)      "Cause". The term "Cause" shall mean:

                           (A)      Material fraud or dishonesty of Employee in
                                    the fulfillment of his duties as an
                                    employee of the Company, including, without
                                    limitation, embezzlement of Company funds;
                                    or

                           (B)      Conviction of a felony under any applicable
                                    criminal code or statute.

         (b)      "Disability". The term "Disability" shall mean the inability
                  of Employee substantially to perform his duties hereunder
                  during any continuous period of more than six (6) months or
                  for an aggregate period of one hundred eighty (180) days in
                  any 365-day period, if after the expiration of such period, a
                  qualified physician selected by the Company determines that
                  Employee will be unable substantially to perform his duties
                  hereunder for an indefinite additional period of time.

         (c)      Termination. At any time during the term of this Agreement,
                  the Company, at its option, may terminate Employee's
                  employment hereunder upon written notice (i) for Cause, (ii)
                  if Employee suffers a Disability, (iii) if Employee dies, or
                  (iv) if the Company does not close on its acquisition of DCI.
                  If Employee is terminated pursuant to the preceding sentence,
                  or if Employee quits the employment of the Company, the
                  Company shall be relieved of any obligation hereunder except
                  for the payment of any salary for periods worked but for
                  which salary has not been paid, the reimbursement of
                  reasonable expenses theretofore incurred in the course of
                  employment and accrued benefits.

         (d)      Termination Payment. If Employee is terminated by the Company
                  for any reason other than (i) for Cause, (ii) because
                  Employee suffers a Disability, (iii) because Employee dies;
                  or (iv) because the Company does not close on its acquisition
                  of DCI, then the Company shall pay Employee an amount equal
                  to the product of his monthly base salary multiplied by the
                  number of months remaining in the one year period of
                  employment set forth in Section 1 hereof; payable in monthly
                  installments equal to his monthly base salary at the time of
                  termination, beginning on the first day of the month
                  following such termination and continuing until the full
                  amount has been paid. Payments will be reduced by the amount
                  the Employee is paid from others for services during the
                  payment period. Employee agrees that such payments shall be
                  his sole remedy for termination of employment with the
                  Company.

7.       Non-Disclosure and Covenant Not to Compete.

                                       2

         (a)      Non-Disclosure. During the term of this Agreement and from
                  and after the termination of this Agreement, Employee shall
                  not, except as required by law or to perform his duties under
                  this Agreement, divulge, disclose or communicate to any
                  person, firm or corporation, any "confidential information".
                  The term "confidential information" includes without
                  limitation, information and know-how about the business of
                  the Company (or any division, subsidiary, stockholder, or
                  affiliate of the Company) including but not limited to,
                  methods of operation, cost or pricing information, product
                  development, technology, processes, plans, research data,
                  prospect files, customer lists, marketing or bid information,
                  or supplier lists, excluding such information that was in the
                  public domain at the time it was acquired by Employee or
                  which comes into the public domain otherwise than through a
                  disclosure by a person or entity owing a duty of
                  confidentiality to the Company or any stockholder,
                  subsidiary, or other affiliate of the Company. If
                  confidential information is contained in any document or
                  writing or is fixed in any other tangible form, magnetically,
                  electronically or otherwise, and if such confidential
                  information is in Employee's possession or under his control,
                  he shall return such information and any copies thereof to
                  the Company upon termination of his employment. Employee
                  shall not directly or indirectly, take, copy, or transfer, in
                  any manner whatsoever, any of the business records or
                  confidential information of the Company (or any division,
                  subsidiary, stockholder or affiliate of the Company). If
                  Employee becomes aware of the possession of confidential
                  information by individuals other than employees of the
                  Company, he shall promptly bring such matter to the attention
                  of the Board of Directors of the Company.

         (b)      Non-Compete. While employed by the Company and for a period
                  of up to one year, or until the date of the last termination
                  payment under 6(c) if termination payments are made,
                  thereafter Employee shall not, directly or indirectly:

                  (i)      Engage (whether for compensation or without
                           compensation) as an individual proprietor, partner,
                           stockholder, officer, employee, director,
                           consultant, joint venturer, lender, or in any other
                           capacity whatsoever (otherwise than as the holder of
                           no more than 1% of the total outstanding stock of a
                           publicly held company) in any business activity or
                           business activities that compete for customers in
                           the contract electronic manufacturing or liquid
                           crystal display production business; or any other
                           business at the time of termination engaged in by
                           the Company (or any division, subsidiary
                           stockholder, or affiliate of the Company).

                  (ii)     Either for himself or for any other person, firm or
                           corporation, solicit, divert or take away or attempt
                           to solicit, divert or take away any person, firm or
                           corporation who was or is a customer, supplier,
                           prospective customer, or agent of the Company (or
                           any division, subsidiary, stockholder or affiliate
                           of the Company); or

                  (iii)    Recruit, attempt to induce, induce or in any way
                           influence any person who is engaged by the Company
                           (or any division, subsidiary, stockholder, or
                           affiliate of the Company) as an employee, agent,
                           independent contractor, or otherwise, to terminate
                           his or her engagement or to engage or otherwise
                           participate in a business activity directly or
                           indirectly competitive with the Company (or any
                           division, subsidiary, stockholder, or affiliate of
                           the Company).

         (c)      Scope of Restrictions. The restrictions set forth in this
                  Section 7 are considered by the parties to be reasonable.
                  However, if any such restriction is found to be unenforceable
                  because it extends for too long a period of time or over too
                  great a range of activities or in too broad a geographic
                  area, it shall be interpreted to extend only over the maximum
                  period of time, range of activities or geographic area as to
                  what it may be enforceable.

         (d)      Remedies. In the event of a breach or a threatened breach of
                  this Section 7, the Company shall be entitled to an
                  injunction restraining Employee from committing or continuing
                  such breach, as well as to any and all other legal and
                  equitable remedies permitted by law.

8.       Miscellaneous.

         (a)      Arbitration. Any controversy or claim arising out of or
                  relating to this Agreement or the breach thereof, including
                  but not limited to any dispute regarding the determination of
                  "Cause" under Section 6 hereof, shall be settled by
                  arbitration in Overland Park, Kansas, in accordance with the
                  rules of the American Arbitration Association.

         (b)      Successors and Assigns. This Agreement shall be binding upon
                  and inure to the benefit of the parties, the successors and
                  assigns of the Company, and the heirs, executors,
                  administrators, successors and assigns of Employee. Employee
                  shall have no right to delegate his duties or to assign his
                  rights under this Agreement. The parties agree that upon
                  closing the acquisition of DCI by the Company, the
                  obligations of the Company hereunder may be assigned by the
                  Company to DCI, and, except for the obligation to permit
                  participation in the Company option plan, the Company shall
                  have no further obligations hereunder.

         (c)      Governing Law. This Agreement shall be governed by and
                  construed in accordance with the laws of the State of Kansas.

option to purchase up to an aggregate of 50,000 Shares of Common Stock of the
Company (the "Option Shares"), in accordance with the vesting schedule set
forth in Section 3 hereof (the "Option"); provided however, that the Option is
subject to the terms of the Plan and the Stock Transfer Restriction Agreement
for Exercise of Stock Option attached hereto as Exhibit B ("Stock Restriction
Agreement"), the provisions of which are incorporated herein by reference and
the terms of which shall control in the event of any conflict with the terms
hereof. The Option hereby granted is an Incentive Stock Option.

         3.       VESTING OF SHARES. The option to purchase shares of Common
Stock shall cumulatively vest and be exercisable for 10,000 shares of Common
Stock on December 6, 2000, 10,000 shares of Common Stock on December 6, 2001,
10,000 shares of Common Stock on December 6, 2003, 10,000 shares of Common
Stock on December 6, 2004, and 10,000 shares of Common Stock on December 6,
2005; provided, however, that the unvested portions of the Options shall vest
and be exercisable immediately prior to any of the following transactions: (i)
the closing of the Company's sale of all or substantially all of its assets or
(ii) the acquisition of the Company by another entity by means of a merger or
consolidation resulting in the exchange of the outstanding shares of Company's
capital stock for securities or consideration issued or caused to be issued by
the acquiring entity or its subsidiary or (iii) the acquisition from one or
more of the shareholders of the Company of more than fifty percent (50%) of the
Common Stock by a single person or group of persons acting together
(collectively, a "Change in Control Transaction"); provided further, however,
that if the Change in Control Transaction is with any person who is a holder of
Common Stock on the date hereof, or an entity under the control of such person
through stock ownership or otherwise, the unvested portion of the options shall
not vest and the

<PAGE>   2

options shall remain in effect to vest in accordance with the vesting schedule
set forth in this Section 3.

         4.       EXERCISE OF OPTION

         (a)      An Option shall be deemed to be exercised when the Optionee or
other authorized person gives to the Company written notice of such exercise
and full payment for the Option Shares with respect to which the Option is
exercised has been received by the Company. As a condition to the exercise of
an Option, the Company will require the Optionee to execute a Stock Restriction
Agreement.

         (b)      Until the issuance (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company)
of the stock certificate evidencing such Option Shares, no right to vote or
receive dividends or any other rights as a shareholder shall exist with respect
to the Option Shares, notwithstanding the exercise of the Option. The Company
shall issue (or cause to be issued) such stock certificates promptly upon
exercise of the Option. No adjustment will be made for a dividend or other
right for which the record date is prior to the date of the stock certificate
is issued, except as provided in Section 12 of the Plan.

         (c)      Exercise of an Option in any manner shall result in a decrease
in the number of Option Shares that thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Option
Shares as to which the Option is exercised.

         5.       EXERCISE PRICE AND CONSIDERATION.

         (a)      EXERCISE PRICE. The per Share exercise price for the Option
Shares to be issued pursuant to exercise of an Option shall be two and
one-quarter dollars ($2.25), which is equal to the closing price per share of
the Common Stock on the date hereof as listed on the NASDAQ National Market
System as reported in The Wall Street Journal.

         (b)      FORM OF CONSIDERATION. The consideration to be paid for the
Option Shares to be issued upon exercise of an Option, including the method of
payment, shall be determined by the Board of Directors and may consist entirely
of cash, check, other shares of Common Stock having a fair market value on the
date of surrender equal to the aggregate exercise price of the Option Shares as
to which said option shall be exercised, or any combination of such methods of
payment, or such other consideration and method of payment for the issuance of
Option Shares to the extent permitted under the laws of the state of
incorporation of the Company. In making its determination as to the type of
consideration to accept, the Board of Directors shall consider if acceptance of
such consideration may be reasonably expected to benefit the Company.

         (c)      FAIR MARKET VALUE. The fair market value of shares of Common
Stock delivered to the Company as payment of the purchase price upon exercise
of an Option shall be determined by the Board in its discretion; provided,
however, that where there is a public market for the Common Stock, the fair
market value per share of Common Stock shall be the mean of the bid and asked
prices (or the closing price per

<PAGE>   3

share if the Common Stock is listed on the National Association of Securities
Dealers Automated Quotation ("NASDAQ") National Market System) of the Common
Stock for the date of grant, as reported in The Wall Street Journal (or, if not
so reported, as otherwise reported by the NASDAQ System) or, if the Common
Stock is listed on a stock exchange, the fair market value per share shall be
the closing price on such exchange on the date of grant of the Option, as
reported in The Wall Street Journal.

         6.       TERM OF OPTION.

         (a)      GENERAL RULE. Except as provided in Section 6(b) and Section
6(c) hereof and in Section 10 and Section 12 of the Plan, the term of each
Option granted pursuant to Section 2 hereof shall be ten (10) years from the
date hereof.

         (b)      EMPLOYMENT OF OPTIONEE TERMINATED. Notwithstanding anything
provided to the contrary in the Plan, if Optionee's employment with the Company
or any Subsidiary is terminated by the Company or any Subsidiary (i) for fraud
or dishonesty of Optionee in connection with fulfillment of his duties and
responsibilities as an employee of the Company or any Subsidiary, including
without limitation, embezzlement of Company or Subsidiary funds; or (ii)
because employee is charged with a felony under any applicable criminal code or
statute, or (iii) if Optionee quits the employment of the Company or any
Subsidiary, then all unexercised Options, whether vested or unvested, shall
terminate immediately upon such termination of employment. If Optionee's
employment with the Company or any subsidiary is terminated for a reason other
than those described in the preceding sentence the unvested portion of the
Option shall terminate immediately and the entire portion of the Option which
was vested prior to termination of Employee's employment, to the extent that it
was exercisable for sixty (60) days following Employee's termination date. To
the extent that the Option was not exercisable on the Employee's termination
date, or if the Option is not exercised (to the extent it was entitled to be
exercised), within the 60 day period, the Option shall terminate.

         (c)      BREACH OF NON-DISCLOSURE COVENANT NOT TO COMPETE.
Notwithstanding anything provided to the contrary in the Plan, if Optionee
breaches any applicable nondisclosure covenant or covenant not to compete set
forth in any employment agreement between Optionee and the Company or a
Subsidiary, or otherwise applicable to Optionee under the law of the
jurisdiction where Optionee is employed, then all unexercised Options, whether
vested or unvested, shall immediately terminate.

         7.       NON-TRANSFERABILITY OF OPTIONS. The Option may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner
other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.

         8.       CONDITIONS UPON ISSUANCE OF OPTION SHARES.

         (a)      Option Shares shall not be issued pursuant to the exercise of
an Option unless the exercise of such Option and the issuance and delivery of
such Option Shares

<PAGE>   4

pursuant thereto shall comply with all relevant provisions of law, including,
without limitation, the Securities Act of 1933, as amended, the Securities
Exchange Act of 1934, as amended, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Common
Stock may then be listed, and shall be further subject to the reasonable
approval of counsel for the Company with respect to such compliance.

         (b)      As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Option Shares are being purchased only for
investment and without any present intention to sell or distribute such Option
Shares if, in the reasonable opinion of counsel for the Company, such a
representation is required by any of the aforementioned relevant provisions of
law.

         (c)      As a condition to the issuance of Option Shares, the Optionee
shall (a) remit to the Company at the time of any exercise of the Option any
taxes required to be withheld by the Company under federal, state or local laws
as a result of the exercise of the Option, and/or (b) instruct the Company to
withhold in accordance with applicable law from any compensation payable to the
Optionee the taxes required to be held by the Company under federal, state or
local laws result of the exercise of the Option. The determination of the
amount of any such withholding shall be made by the Company in its sole
discretion.

         (d)      All Option Shares issued pursuant to the exercise of the
Option shall be subject to the terms and provisions of the Stock Restriction
Agreement, an example of which is attached hereto as Exhibit B.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above written.
