THIS FIRST AMENDMENT TO REAL ESTATE PURCHASE AGREEMENT (this “Amendment”), dated
as of December 23, 2013, (and for all other purposes, the Effective Date shall
remain July 30, 2013) is made between Cerner Property Development, Inc., a
Delaware corporation, its successors and assigns (“Purchaser”), and Trails
Properties II, Inc., a Missouri corporation (“Seller”).

WHEREAS, the Parties previously entered into a certain Real Estate Purchase
Agreement dated July 30, 2013 (the “Agreement”) regarding the purchase and sale
of certain real property as described therein.

WHEREAS, the Parties desire to enter into this Amendment for the purposes stated
herein.

WHEREAS, capitalized terms not otherwise defined or redefined herein shall have
the same meaning as provided in the Agreement.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Parties agree as follows:
    
1. Seller’s Land. The real property legally described on Exhibit A of this
Amendment shall be added to Exhibit A-1 of the Agreement, in addition to all
other real property currently described in Exhibit A-1.

2. Purchaser Tax Increment Financing Approvals. The Parties acknowledge that
Purchaser has had secured tax increment financing approvals that will be used in
place of the TIF Plan. Accordingly, Section 5.1(s) and Section 6.1(h) shall each
be deleted in their entirety and replaced with “Intentionally Deleted.”

3. Demolition Work. The Parties acknowledge that certain tenancies affecting the
Seller’s Land will delay the completion of portions of the Demolition Work
beyond the date that is sixty (60) days after Closing, and any such instances
are hereby deemed “excusable delays” under Section 5.6 of the Agreement.
Seller’s obligation to complete the Demolition Work within sixty (60) days after
Closing shall be extended to allow Seller ninety (90) days after Seller comes
into possession of any portion of the Seller’s Land subject to such tenancies to
complete any portion of the Demolition Work related to such portion of the
Seller’s Land. The Parties acknowledge that Seller’s contractor for the
Demolition Work currently estimates that the costs necessary to complete any
Demolition Work that will not be completed as of Closing is (including
retainage) Eight Hundred Twenty Eight Thousand Four Hundred Sixty Two Dollars
and Ninety Four Cents ($828,462.94), with the components of such estimate set
forth on Exhibit B of this Amendment. Accordingly, pursuant to Section 5.6 of
the Agreement, Seller shall escrow with the Title Company Two Hundred Percent
(200%) of such amount, or One Million Six Hundred Fifty Six Thousand Nine
Hundred Twenty Five Dollars and Eighty Eight Cents ($1,656,925.88). Upon the
completion of any portion of the Demolition Work and payment in full to Seller’s
contractor for such portion of the Demolition Work,

Purchaser and Seller hereby agree to promptly direct the Title Company to
release to Seller from such escrow an amount equal to Two Hundred Percent (200%)
of the cost of such portion of the Demolition Work. In the event that the cost
of completing the Demolition Work exceeds the amount contemplated herein, Seller
shall be responsible for any overage necessary to complete the Demolition Work.
In the event that Seller fails to complete any portion of the Demolition Work
within sixty (60) days of Closing, or within ninety (90) days of coming into the
possession of any portion of the Seller’s Land subject to a tenancy as
contemplated herein, subject to excusable delays as contemplated in Section 5.6
of the Agreement, the balance of the escrow shall be released to Purchaser, and
Seller shall be released from any obligation to the complete the Demolition
Work.

4. Existing TIF Plan. Upon request of Purchaser, at Closing or at any time after
Closing, Seller agrees to assign, subject to receipt of any consents from the
Commission or the City, any and all right, title and interest of Seller to the
TIF Plan, including assignment of Seller's designation as the redeveloper under
the TIF Plan, and to assist and cooperate with Purchaser to obtain all necessary
Commission and City approvals associated therewith. The covenants and agreements
set forth in this Section 4 shall survive the Closing.

5. Post-Closing Title Matters. Seller shall utilize commercially reasonable
efforts (including expenditure of reasonable legal fees of Seller's counsel)
following the Closing to cooperate with Purchaser’s efforts in removing or
resolving to Purchaser's reasonable satisfaction the following exception items
listed in the Pro Forma Title Insurance Policy No. 619698 issued by the Title
Company and attached hereto as Exhibit B to this Amendment: 9, 27, 58, 60 and
297. In the event the Title Company identifies additional substantive and
material exception items not included on Exhibit B prior to Closing, Seller
shall utilize commercially reasonable efforts (including expenditure of
reasonable legal fees of Seller's counsel) following the Closing to cooperate
with Purchaser’s efforts in removing or resolving to Purchaser's reasonable
satisfaction those additional exception items. In no event shall Seller be
required to threaten or undertake litigation or any other similar action as a
part of its cooperation with Purchaser’s efforts under this Section. Seller
shall not be required to expend any costs pursuant to this Section other than
reasonable legal fees of Seller’s counsel, and Seller’s costs in cooperating
with Seller’s efforts pursuant to this Section shall not exceed Twenty-Five
Thousand Dollars ($25,000.00). Purchase acknowledges that the actions of
third-parties over which Seller has no control may be required to address the
exceptions contemplated in this Section, and Seller makes no warranty that such
exceptions can be remedied. The covenants and agreements set forth in this
Section 5 shall survive the Closing.

every other term and condition of the Agreement shall remain unchanged and in
full force and effect without modification.
