                                                                 ---------------

located in the northeast lower level comprising approximately 2,500 square feet
which Landlord reserves the right to occupy.

         3.       MINIMUM ANNUAL RENTAL. Notwithstanding anything to the
contrary, the Minimum Annual Rental shall be as follows:

                   LEASE PERIOD                MINIMUM ANNUAL RENTAL

         5.       PARKING. Article 44 of the Lease is amended to provide that
Landlord shall provide Tenant with all parking spaces (exclusive of visitor and
handicap parking) available in the parking lot located on the Commercial
Building Parcel for Tenant's use at all times.

         6.       RENEWAL OPTION. Section 1 of the Fourth Modification Agreement
is replaced in its entirety with the following:

         (A)      Provided that Tenant is not in default beyond any applicable
                  period to cure at any time from the exercise of the option
                  until the expiration of the Lease Expiration Date, Tenant
                  shall have an option to renew this Lease for one (1)
                  additional term of five (5) years (the "Renewal Term"),
                  exercisable by giving Landlord written notice of the exercise
                  by not less than 360 days before the expiration of the Lease
                  Expiration Date (the "Expiration Date"). The Renewal Term
                  shall be on the same terms, covenants and conditions as set
                  forth in the Lease with respect to the Extended Term, except
                  that the Minimum Annual Rental (the "MAR") payable during the
                  Renewal Term shall be computed as herein provided.

         (B)      For the Renewal Term, MAR shall be computed as an amount equal
                  to ninety percent (90%) of the then prevailing Market Rate (as
                  hereinafter defined) of the Leased Premises, as if vacant with
                  the then existing improvements, based on its use as general
                  office space, and for comparable office buildings in the
                  Kansas City metropolitan area, adjusting the Base Year
                  Operating Expenses to mean Operating Expenses incurred during
                  calendar year 2007. In determining Market Rate, the parties
                  shall also take into account the condition of the Leased
                  Premises at the commencement of the Renewal Term, the length
                  of the Renewal Term, Tenant's obligation to pay its
                  proportionate share of increases in Operating Expenses as
                  herein provided, the absence of any obligation of Landlord to
                  provide any tenant improvement to the Leased Premises for the
                  Renewal Term, and such other factors as are relevant in the
                  opinion of the parties making such determination.

         (C)      The term "Market Rate" shall mean the rate per square foot of
                  rentable area then being quoted for comparable office
                  buildings with the characteristics noted in paragraph 1(B)
                  above. If the parties do not agree upon the Market Rate within
                  thirty (30) days after Tenant exercises its option to renew,
                  each party shall choose a "Qualified Appraiser" who shall make
                  such determination on its behalf and submit the same to the
                  other party (together with the information forming the basis
                  for such determination) within seventy-five (75) days after
                  Tenant exercises its option to renew (with each party paying
                  the fee for its own appraiser). "Qualified Appraiser" shall
                  mean an appraiser who is independent, licensed and a member of
                  the American Institute of Real Estate Appraisers (the
                  "AIREA"). Unless the two Qualified Appraisers agree to the
                  Market Rate within fifteen (15) days following delivery of the
                  last of the two appraisals, the two Qualified Appraisers shall
                  choose a third Qualified Appraiser and notify Landlord and
                  Tenant of such choice. Each party shall share equally the cost
                  of the third Qualified Appraiser. If the two Qualified
                  Appraisers cannot or do not agree on the choice of a third
                  Qualified Appraiser within ten (10) days following expiration
                  of the immediately preceding fifteen (15) day period, the
                  third Qualified

                                       2

<PAGE>

                  Appraiser shall be selected by the most senior officer of the
                  Kansas City Chapter or branch of the AIREA or its successor,
                  or if there shall be no successor, a professional organization
                  having a function, standards and qualifications similar
                  thereto. Within thirty (30) days after his or her appointment,
                  the third Qualified Appraiser shall determine the Market Rate
                  of the Leased Premises, in the condition as specified in
                  paragraph 1(B) and taking into account the factors specified
                  in paragraph 1(B), by selecting as such Market Rate either the
                  Market Rate proposed by Tenant's Qualified Appraiser or the
                  Market Rate proposed by Landlord's Qualified Appraiser, and
                  submitting such determination to each party in writing.

         (D)      Based on said mutual agreement or third Qualified Appraiser's
                  determination, Landlord and Tenant shall promptly thereafter
                  execute a written agreement establishing the aforesaid MAR,
                  which shall be binding upon the parties commencing with the
                  first year of the Renewal Term.

         7.       PURCHASE OPTION. Tenant is hereby granted the right,
exercisable by written notice to Landlord at any time after March 1, 2005 and
during the term of this Agreement, to purchase the Commercial Building Parcel.
Upon such exercise of Tenant's option, as to the Commercial Building Parcel, the
Lease shall also be deemed to be a real estate sale contract between Landlord,
as Seller, and Tenant, as Buyer, on and subject to the following terms and
conditions:

         (A)      The purchase price (the "Purchase Price") for the Commercial
                  Building Parcel shall be Four Million Six Hundred Eighty Five
                  Thousand One Hundred and No/100 Dollars ($4,685,100.00).

         (B)      The closing date (the "Closing Date") shall be specified in
                  Tenant's written notice exercising its purchase option with
                  such Closing Date to be within ninety (90) days after notice.

         (C)      Landlord shall deliver to Tenant, not later than thirty (30)
                  days after the exercise of Tenant's purchase option hereunder,
                  a survey of the Commercial Building Parcel conducted not more
                  than ninety (90) days prior to the Closing Date by a surveyor
                  licensed by the State of Kansas, such survey to be sufficient
                  in form to cause the deletion from the title policy referred
                  to in paragraph (D) below of any exceptions concerning matters
                  which would be disclosed by a survey of the Commercial
                  Building Parcel or easements or claims of easements not shown
                  by the public records. Said survey shall also show the
                  location of all easements, rights-of-way and other matters
                  disclosed by the title commitment referred to in paragraph (D)
                  below. If such survey reveals any encroachments, overlaps or
                  other matters which are not acceptable to Tenant, then, unless
                  Tenant shall waive such objections, Tenant shall revoke its
                  exercise of its option hereunder and continue its occupancy of
                  the Commercial Building Parcel upon and subject to all of the
                  terms and provisions hereof.

         (D)      Landlord shall furnish Tenant, at Landlord's expense, an
                  Owner's Policy of Title Insurance, in form reasonably
                  acceptable to Tenant, in the amount of the Purchase Price,
                  issued by a title insurance company

                                       3
<PAGE>

                  approved by Tenant and authorized to insure titles in the
                  State of Kansas, insuring a merchantable fee simple title in
                  Tenant as of the Closing Date. Landlord shall, not later than
                  twenty (20) days after the exercise of Tenant's purchase
                  option hereunder, deliver to Tenant a commitment for such
                  title policy. If such commitment contains any matters which
                  are not acceptable to Tenant, Tenant shall, within twenty (20)
                  days after receipt of such commitment, notify Landlord in
                  writing of such objections. Landlord hereby covenants and
                  agrees to use its reasonable efforts to correct such
                  objections (but shall not be required to commence any
                  litigation against any third parties); provided, however, that
                  if Landlord is unable to correct such objections within thirty
                  (30) days after receipt of written notice of objection from
                  Tenant, then, unless Tenant shall elect to waive such
                  objections, Tenant shall revoke its exercise of its option
                  hereunder and continue its occupancy of the Leased Premises
                  upon and subject to all of the terms and provisions hereof.
                  Landlord covenants and agrees to execute and deliver to the
                  title company a seller's affidavit in such reasonable form as
                  the title company may require.

         (E)      The risk of loss shall be upon Landlord prior to the Closing
                  Date. In the event that prior to the Closing Date any of the
                  improvements on the Commercial Building Parcel are destroyed
                  or damaged by fire or other casualty, Tenant may, at its
                  option, enforce its rights under this option and accept an
                  assignment of the insurance proceeds payable as a result of
                  such casualty, or, in the event Tenant elects not to proceed
                  with the purchase of the Commercial Building Parcel pursuant
                  to its rights under this option, Tenant shall revoke its
                  exercise of its option hereunder and continue its occupancy of
                  the Commercial Building Parcel upon and subject to all of the
                  terms and provisions hereof.

         (F)      Landlord shall convey the Commercial Building Parcel on the
                  Closing Date to Tenant by a general warranty deed, properly
                  executed and conveying the Commercial Building Parcel free and
                  clear of all liens and encumbrances whatsoever, except as
                  hereinabove provided.

         (G)      In the event that, after Tenant's exercise of its option
                  hereunder, either party shall default in its agreements set
                  forth in this Section 7, the non-defaulting party shall have
                  all rights and remedies available at law, in equity or
                  hereunder.

         (H)      Right to Exchange Real Property. Buyer agrees that Seller,
                  through the use of a qualified intermediary, may desire to
                  transfer the Commercial Building Parcel through a tax free
                  exchange, deferred exchange or reverse exchange of real
                  property pursuant to Section 1031 of the Internal Revenue
                  Code; provided, however (i) in no event shall any such
                  exchange, or Seller's inability to complete any such exchange,
                  impair or otherwise affect the Closing Date, (ii) Buyer shall
                  have no obligation or liability to Seller or any other party
                  in any respect for any matters in connection with any such
                  exchange other than payment of the Purchase Price in exchange
                  for the conveyance to Buyer of fee simple title to the
                  Commercial Building Parcel by deed subject only to those
                  matters permitted hereunder and (iii) Seller shall indemnify
                  and hold Buyer


                                       4

<PAGE>

                  harmless from and against any claims, actions, liability and
                  expense in connection with each such exchange.

         8.       RIGHT OF FIRST REFUSAL. In the event during the term of this
Lease Landlord receives an offer from a third party to purchase Landlord's
interest in the Commercial Building Parcel which Landlord desires to accept (the
"Third Party Offer"), Landlord shall (provided Tenant is not then in default
beyond the expiration of any applicable notice and grace period provided for the
curing of such default), furnish Tenant with a copy of such Third Party Offer.
During the ten (10) business day period following Tenant's receipt of such Third
Party Offer, Tenant shall have the pre-emptive right to purchase the Commercial
Building Parcel from Landlord on the same terms and conditions as are set forth
in the Third Party Offer. If Tenant timely elects to purchase the Commercial
Building Parcel, the parties shall promptly enter into a purchase and sale
agreement and the closing of such transaction shall be consummated on a date
selected by Tenant, but which shall occur not later than sixty (60) days after
Tenant's receipt of the Third Party Offer. If Tenant does not timely elect to so
purchase the Commercial Building Parcel, Landlord shall be free to accept the
Third Party Offer and to consummate the sale of the Commercial Building Parcel,
in which case, the provisions of this Paragraph shall automatically terminate
and shall be of no further force or effect.

         9.       LANDLORD'S WORK. Landlord agrees to perform the work described
on the attached Exhibit A within 120 days after the date hereof except that the
requirement to clean all carpets in Item 1 of Floor Covering shall be completed
between the dates of May 15, 2003 and June 1, 2003.

         10.      OTHER TERMS. Except as modified herein, all other terms and
conditions of the Lease shall remain unmodified and in full force and effect.

         The parties have executed this Agreement effective as of the date
indicated above.
