                                  "COMPANY"

    AND                      C. HOWARD WILKINS, JR

WHEREAS, Optionee has agreed to personally guarantee a line of credit for the
amount of Three Million Seven Hundred Thousand Dollars ($3,700,000) which the
Company will obtain from Intrust Bank, Wichita, Kansas ("Line of Credit").

WHEREAS, the Company desires to compensate Optionee for such guarantee by
granting him an option to purchase common stock of the Company.

NOW THEREFORE, in consideration of the promises and mutual covenants herein
contained, the Company and Optionee hereby agree as follows:

1.  GRANT OF OPTIONS.  The Company hereby grants to Optionee, subject to the
    terms and conditions set forth herein, the right and option to purchase
    from the Company all or any part of an aggregate of four hundred
    thirty-seven thousand five hundred twenty-five (437,525) shares of common
    stock of the Company ("Stock").

2.  EXERCISE PRICE/VESTING OF OPTION.  The exercise price and manner in which
    such option becomes vested in Optionee is as follows:

    (a)  Optionee shall be vested in and entitled to purchase two hundred one
         thousand twenty-five (201,025) shares of Stock from the Company for a

         the date of this Agreement.

    (b)  Optionee shall be vested in and entitled to purchase an additional
         eleven thousand eight hundred twenty-five (11,825) shares of stock for
         every One Hundred Thousand Dollars ($100,000) which Company borrows
         under the Line of Credit

<PAGE>

         until the aggregate number of shares granted pursuant to paragraph 1
         hereof has been reached.  The exercise price for such shares of Stock
         shall be Two Dollars Fifty Cents ($2.50) per share.

3.  EXERCISE OPTION PERIOD. The option granted hereby shall extend for a period
    of seven (7) years from the date the Company borrows under the Line of
    Credit and the option becomes vested pursuant to paragraph 2(b) hereof and
    shall terminate five (5) years from such date.

4.  ADJUSTMENTS OF SHARES AND EXERCISE PRICE.  In the event of any stock
    dividend or subdivision of the shares of common stock of the Company into a
    greater number of shares (e.g. stock split), the purchase price hereunder
    shall be proportionately reduced and the number of shares subject to this
    Agreement shall be proportionately increased; conversely, in the event of
    any contraction of the outstanding shares of common stock of the Company
    (e.g. reverse stock split), the purchase price hereunder shall be
    proportionately increased and the number of shares subject to this
    Agreement shall be proportionately reduced.

5.  MANNER OF EXERCISING OPTION/PAYMENT OF PURCHASE PRICE.  The option granted
    under the terms of this Agreement may be exercised by Optionee, subject to
    the provisions contained herein, by giving written notice to the Company of
    an election to exercise such option.  Such notice shall specify the number
    of shares to be purchased hereunder and the date upon which such purchase
    is to be made.  Such notice shall be mailed and delivered to the Company at
    its principal business office, 302 North Rock Road, Suite 200, Wichita,
    Kansas 67206, Attention: Corporate Secretary, postage prepaid, at least two
    (2) and not more than thirty (30) full business days prior to the date of
    purchase specified in such notice.  Upon receipt of such notice, and
    subject to the provisions contained herein, the Company shall, on the date
    specified in such notice and against receipt in cash, deliver to Optionee
    on the date specified in such notice certificates representing the shares
    so purchased.  All requisite original issuance or transfer documentary
    stamp taxes shall be paid by the Company.

6.  TRANSFERABILITY OF OPTION.  The option granted to Optionee pursuant to the
    terms of this Agreement may be assigned by Optionee provided such
    assignment complies with the Securities Act of 1933 and provided further
    that Optionee obtains prior approval from Company and its legal counsel
    consenting to such assignment.

7.  INVESTMENT REPRESENTATION.  Upon demand by the Company for such a
    representation, Optionee shall deliver to the Company, at the time of any
    exercise of an option or portion thereof, a written representation that the
    shares to be acquired upon such exercise are to be acquired for investment
    and not for resale, except as provided by paragraph 8 hereof, or with a
    view to the distribution thereof.  Upon such demand, delivery of such
    representation prior to the delivery of any shares issued upon exercise of
    an option and


                                          2


<PAGE>

    prior to the expiration of the  option period shall be a condition
    precedent to the right of the Optionee or such other person to purchase any
    shares of Stock.

8.  RESTRICTED TRANSFERABILITY.  Optionee understands and acknowledges that no
    granted option or the shares to be issued upon its exercise have been or
    will be registered under the Securities Act of 1933 or any state securities
    law.  Optionee understands that certificates representing the shares to be
    issued upon the exercise of the options will bear customary legends
    restricting transfer of the shares when issued and will not be freely
    transferable.

9.  COMPLIANCE WITH LAWS AND REGULATIONS.  The grant and exercise of options
    hereunder, and the obligation of the Company to sell and deliver shares
    hereunder, shall be subject to all applicable federal and state laws, rules
    and regulations, and to such approvals by any government or regulatory
    agency as may be required.  The Company shall not be required to issue or
    deliver any certificates for shares of stock, if in its sole determination,
    such action would violate any applicable laws, rules or regulations.

10. RIGHTS AS A SHAREHOLDER.  Optionee or a permitted transferee of any option,
    shall have no rights as a shareholder with respect to any shares covered by
    the option granted under this Agreement until the date of issuance of the
    stock certificate for such shares.  Other than is provided in Paragraph 4,
    no adjustments shall be made for dividends (ordinary or extraordinary) or
    distributions, whether in cash, securities or other properties, or other
    rights for which the record date is prior to the date such stock
    certificate is issued.

11. SCOPE OF AGREEMENT.  This Agreement shall bind and inure to the benefit of
    this Company, its successors and assigns and Optionee and any heirs,
    personal representatives, successors or assigns of Optionee permitted by
    Paragraph 6 above.
