                      AMENDED AND RESTATED PROMISSORY NOTE

$7,450,000.00                                                December 30, 1999

The undersigned ("Borrower") promises to pay to the order of Bank of America,
N.A., successor to NationsBank, N.A., successor to Boatmen's First National Bank
of Kansas City ("Bank"), at such address as Bank shall designate from time to
time ("Bank's Address") the principal sum of Seven Million Four Hundred Fifty
Thousand Dollars ($7,450,000.00), plus interest thereon as required below.

From the effective rate hereof, interest shall accrue on the outstanding
principal balance of this Note at the Bank's Prime Rate of interest per annum,
as such Prime Rate changes from time to time, minus one per cent (1%). Bank's
Prime Rate of interest is that interest rate established by Bank from time to
time as its Prime Rate, which rate may not be the best or lowest rate charged by
Bank to its customers. Changes in such rate shall be made without notice to the
undersigned and shall be effective on the date of each such change.

After maturity, whether upon the lapse of time or by acceleration, all past due
principal, and interest to the extent permitted by law, shall bear interest
until paid at the same rate as would be applicable if it was before maturity,
plus 2.0%. All interest shall be calculated on the basis of the days actually
elapsed over a year deemed to consist of 360 days.

Notwithstanding anything to the contrary contained in this Note, the rate of
interest payable under this Note shall not exceed the maximum amount Bank
lawfully may charge. If Bank receives anything of value deemed interest under
applicable law which would exceed the maximum amount of interest permissible
under applicable law, or if application of any variable rate, used of a 360-day
year or any other circumstance, including acceleration, prepayment, or demand,
would cause the effective interest rate under this Note to exceed such maximum
rate, then the interest rate under this Note shall be deemed reduced to such
maximum rate, and the excessive interest shall, at the option of Bank, be
applied to the reduction of the outstanding principal balance under this Note or
refunded to Borrower.

The entire outstanding principal balance and all accrued interest thereon shall
be due and payable on JULY 31, 2000 ("Final Maturity").

Until Final Maturity, Borrower shall make payments as follows:

      QUARTERLY principal payments of $187,500 each, plus (at the same time)
      accrued interest, commencing on July 31, 1999 and continuing on the last
      day of each quarter-year thereafter, until July 31, 2000, on which date
      the entire unpaid principal balance and all interest accrued thereon shall
      be due and payable.

This Note is secured by that certain Security Agreement dated June 7, 1994 and
the collateral specified therein. This Note is also related tot he terms of that
certain Agreement dated

<PAGE>

January 2, 1997 (as such Agreement has been amended by that certain Amendment of

Documents dated January 31, 1999, that certain Third Amendment of Loan Documents

Note, in addition to any other rights the holder may have, shall have the right
to offset against amounts due under this Note all deposit, funds, securities,
and other property of Borrower in the possession of the holder.

If Borrower does not pay any principal or interest when due hereunder, or if
Borrower or any other party defaults under or fails to perform or pay any
covenant or obligation in any agreement that secures this Note or has been
executed and delivered to the holder hereof in connection with the indebtedness
evidenced by this Note, the holder hereof my declare all principal and unpaid
accrued interest to be immediately due and payable. Failure to do so at any time
shall not constitute a waiver of the right of the holder hereof to do so at any
other time.

makers, endorsers, or guarantors, by becoming parties to this Note, waive
presentment for payment, notice of dishonor, protest, notice of protest, and all

Note, whenever made, and waives notice thereof. Every such party by becoming a
party to this Note further waives any and all defenses which such party may have

extent permitted by law) pay all costs of collection, including but not limited

Title:  PresidentPROMISSORY NOTE

$2,500,00.00                                                       July 15, 1994

         FOR VALUE  RECEIVED,  the  undersigned,  BLUE VALLEY  BUILDING CORP., a
Kansas  corporation  ("Borrower"),  with an address at P.O. Box 26128,  Overland
Park,  Kansas  66225,  promises to pay to BUSINESS  MEN'S  ASSURANCE  COMPANY OF
AMERICA,  a  Missouri  corporation,  with an  address  at c/o  Charter  American
Mortgage  Company,  2001 Shawnee Mission  Parkway,  Mission Hills,  Kansas 66205
("Lender") or to order,  the principal sum of Two Million Five Hundred  Thousand
and  00/100  Dollars  ($2,500,000.00),  together  with  interest  on the  unpaid
principal  balance of this Note at the "Interest Rate" (as defined below) in the
amounts and in the manner set forth herein.

         1.       Term.

         (a) The term of this Note (the "Loan Term") shall  commence on the date
hereof and shall end on August 1, 2009 (the "Maturity  Date").  "Loan Year",  as
used herein,  shall mean the twelve (12) month period  beginning on the due date
of the  first  "Monthly  Payment"  (as set forth in  Section  3 below)  and each
consecutive twelve (12) month period thereafter during the Loan Term, and "Loan"
shall mean the loan from Lender to Borrower evidenced by this Note.

         (b)  Notwithstanding  the  provisions of paragraph  1(a) above,  Lender
shall have the right to accelerate  the maturity of this Note and to declare the
same  due and  payable  on the last  day of the  tenth  (10th)  Loan  Year  (the
"Accelerated  Maturity  Date"),  by giving notice to Borrower not later than one
hundred  eighty (180) days prior to the  Accelerated  Maturity  Date. The entire
outstanding  principal balance and all accrued and unpaid interest shall then be
due and payable on the Accelerated Maturity Date, without prepayment charge.

         2.       Interest Rate.

         (a) This Note shall bear interest at a rate equal to seven and one-half
percent  (7.50%) per annum (the  "Interest  Rate").  All payments due under this
Note shall be applied  first  against  accrued  interest  and then  against  the
outstanding  principal amount due under this Note. The interest  hereunder shall
be calculated based on a three hundred sixty (360) day year consisting of twelve
(12) months of thirty (30) days each.

         (b) At Lender's  option,  the Interest Rate shall be adjusted as of the
first (1st) day of the eleventh  (11th) Loan Year (the  "Adjustment  Date") to a
rate per annum (the "Adjusted  Interest  Rate")  equivalent to two hundred (200)
basis points above the then current yield of U.S.  Treasury  Securities (i) with
an asking price closest to par, (ii) paying interest semi-annually,  (iii) not a
"zero coupon" obligation or an obligation with an optional prepayment,  and (iv)
having a maturity date closest to the Maturity  Date, as such yield is published
in the Wall  Street  Journal  on the  Adjustment  Date  (or the  next  preceding
publication  date), such yield rate to be applicable  regardless of the schedule
of interest payments under this Note and such Treasury Security, but in no event
shall the Adjusted Interest Rate be less than seven and one-half percent (7.50%)
nor greater than eight and one-half  percent  (8.50%) per annum. If Lender shall
so elect to adjust to the Interest  Rate,  Lender  shall so notify  Borrower not
later  than  sixty  (60)  days  prior to the  Adjustment  Date.  Borrower  shall
thereupon  have a period of one hundred  eighty  (180) days from the  Adjustment
Date in which Borrower may prepay the Loan in full, without prepayment charge or
other penalty.  If Borrower shall not so prepay the Loan prior to the expiration
of such one hundred  eighty (180) day period,  Borrower  shall be deemed to have
accepted the Adjusted  Interest Rate, and this Note
<PAGE>

shall  continue  in full force and effect in  accordance  with its terms and the
Adjusted Interest Rate.  Notwithstanding  the election of Borrower to prepay the
Loan under this  paragraph  (b), the Adjusted  Interest Rate shall be applicable
until the date of such prepayment.

         3.       Monthly Payment; Final Payment.

         (a) The outstanding  principal  balance and accrued interest under this
Note  shall be repaid in monthly  installments  of  principal  and  interest  of
$23,175.31 (the "Monthly Payments").  The first Monthly Payment shall be due and
payable  on the  first  day of  September,  1994,  and on the  first day of each
succeeding month; provided, however, that on August 1, 1994, Borrower shall make
a payment of the accrued  interest  from the date of closing of the Loan through
and  including  the last day of July,  1994.  If not  sooner  paid,  the  entire
outstanding  principal  balance and all accrued and unpaid  interest  under this
Note shall be due and payable on the Maturity Date.

         (b) If the  Interest  Rate shall be adjusted  pursuant to Section  2(b)
above,  then effective as of the first day of the eleventh (11th) Loan Year, the
Monthly Payment shall be adjusted to an amount  sufficient to fully amortize the
then outstanding principal balance of this Note in equal monthly installments of
principal  and  interest  over a period of sixty  (60)  months  at the  Adjusted
Interest Rate.

          4.  Prepayment.  (a)  Borrower  shall not have the right to prepay any
     principal or interest under this Note for the first three (3) Loan Years of
     the Loan Term.  After the third  (3rd) Loan Year,  Borrower  shall have the
     right to prepay the entire  outstanding  principal  balance of this Note on
     the following terms and conditions:

         (1)      Delivery of sixty (60) days prior written notice to Lender;

         (2)      Payment of all accrued  interest and other charges under this
                  Note and all sums due under all other Loan Documents; and

         (3)      Payment  of a  percentage  of the then  outstanding  principal
                  balance  of this  Note,  as a  prepayment  charge,  during the
                  fourth (4th) Loan Year and thereafter, of two percent (2%).

         (b) Notwithstanding the foregoing, Borrower shall have the right, after
the  third  (3rd)  Loan  Year,  to prepay  up to five  percent  (5%) of the then
outstanding  principal balance of this Note, on a non-cumulative  basis, without
prepayment charge, on the due date of any monthly payment,  upon first complying
with the  provisions  of clauses (1) and (2) of  paragraph  (a) above.  Borrower
shall  further  have the right to prepay the Loan,  including  all  interest and
charges  thereunder,  in full, without prepayment charge, on the last day of the
tenth (10th) Loan Year,  even though  Lender shall not have  exercised its right
under Section 1(b) above,  upon first giving notice to Lender not later than one
hundred eighty (180) days prior to the date of prepayment.

         5. Security.  The  indebtedness  evidenced by this Note is secured by a
Mortgage,  Assignment  of Leases and Rents,  Security  Agreement  and  Financing
Statement  dated  as of the  date  hereof  (the  "Mortgage")  and by a  separate
Assignment of Leases and Rents dated as of the date hereof, given by Borrower to
Lender and  encumbering  certain real property and  improvements  located in the

Estate"). This Note, the Mortgage, Assignment of Leases and Rents, Environmental
Indemnity  and any other  instruments  or documents  that evidence or secure the
indebtedness  under  this  Note  are  herein   collectively   called  the  "Loan
Documents",  and the terms of all Loan Documents are incorporated into this Note

of Borrower under this Note and such default is not completely cured by Borrower
