Omitted]  4.             Operating
Expenses and Real Estate Taxes. Tenants obligations under Section 4.2
of the Lease to pay Operating Expenses with respect to the JLL Space shall be
computed using the calendar year ending December 31, 2009 as a base year;
and Tenants obligations under Section 4.2 of the Lease to pay increases
in Real Estate Taxes with respect to the Ninth Amendment Expansion Space shall
be computed using the fiscal year ending June 30, 2009 as the base year.  5.             Effective
Date; Delivery and Condition. (a) The Ninth Amendment Effective Date
shall be the later to occur of (i) February 1, 2009 and (ii) the
date on which Jones Lang LaSalle (the Existing Tenant) vacates and surrenders
the JLL Space and Landlord delivers possession of the Ninth Amendment Expansion
Space to Tenant.  (b)           Tenant acknowledges that, except as explicitly provided in
this Ninth Amendment and the Lease, it is leasing the JLL Space in its current
AS IS condition, without any representation or warranty whatsoever on the part
of Landlord. Tenant currently occupies the Existing Premises and is fully
familiar with their condition and that of the common areas of the Building, and
Tenant acknowledges that, to the best of  3


Tenants knowledge (upon reasonable
investigation and inquiry), the Existing Premises and the JLL Space are in good
condition and suitable for Tenants uses. Without limiting the foregoing,
Tenant agrees that Landlord has no obligation to perform any work in or to
either the Existing Premises or the JLL Space to prepare the same for Tenants
continued use and occupancy.  (c)           Landlord acknowledges that
Tenant desires to make certain alterations or improvements in the JLL
Space to make the same more suitable for Tenants
occupancy. Such alterations or improvements may include tenant improvements to
the Ninth Amendment Expansion Space,
installation of fixtures in the Ninth Amendment Expansion Space, and architectural and engineering expenses in
connection therewith (collectively, the JLL Space Improvements). All Ninth Amendment Expansion
Space Improvements shall be undertaken by
Tenant in strict accordance with the applicable requirements of the Lease
(including without limitation Sections 3.3 and 3.4). The JLL Space Improvements shall be deemed substantially complete
on that date on which the JLL Space
Improvements have been completed except for items of work (and, if
applicable, adjustment of equipment and fixtures) which can be completed after
Tenant has taken occupancy of the JLL Space, or any part thereof, without
causing undue interference with Tenants use of the JLL Space or such part
thereof. To the extent that (i) such work
is substantially completed in accordance with such Lease requirements, and (ii) receipted
invoices (and other material required under the Lease such as, but not limited
to, lien waivers from any contractor or subcontractor performing the JLL
Space Improvements) showing the actual cost
thereof are presented to Landlord during the Term of the Lease, and (iii) at
the time of any advance of funds, there then exists (A) no Event of
Default on the part of Tenant, nor (B) any Actionable Event of Default (as
defined in the Third Amendment), Landlord shall reimburse Tenant, within thirty
(30) days after receipt of each such invoice (together with lien waivers for
all costs theretofore billed), for costs actually incurred by Tenant (excluding
the costs of furniture), as evidenced by such invoices, in connection with the
design and construction of the JLL Space Improvements, but in no event shall Landlord be obligated to reimburse
Tenant more than the lesser of (x) such actual cost, or (y) Three
Hundred Fifty-two Thousand Three Hundred Dollars ($352,300.00), or $25.00 per
square foot of Rentable Area in the JLL Space (the JLL Space Improvements
Allowance). No portion of the JLL Space Improvements Allowance may be applied to costs of
purchasing or installing furniture or wiring/cabling for the JLL Space. If the Existing Tenant vacates and surrenders
possession of the JLL Space prior to January 31, 2009, Landlord shall
grant Tenant reasonable access to the JLL Space from and after such surrender
(and the Existing Tenant vacating the JLL Space) for the purpose of commencing
the JLL Space Improvements in the JLL
Space. To the extent that Tenant has not requested disbursement of any portion
of the JLL Space Improvements Allowance
prior to the expiration or earlier termination of the Lease, Landlord shall
have no further obligation to reimburse Tenant for any such costs incurred by
Tenant. Notwithstanding the foregoing, to the extent that Tenant has not used
the entire JLL Space Improvements Allowance for JLL Space Improvements,
then Tenant shall have the  4


right to use any remaining portion (in
addition to any unused portion of the Eighth Amendment Expansion Space Improvements
Allowance) for Lobby Improvements made by Tenant to the Lobby Area (as those
terms are defined in the Seventh Amendment), provided that Tenant shall not use
more than $25.00 per rentable square foot of Lobby Space area, in the
aggregate, from the Eighth Amendment Expansion Space Improvements Allowance (as
defined in the Eighth Amendment) and the JLL Space Improvements Allowance.  6.Contingency.   Tenant acknowledges that the
Ninth Amendment Effective Date occurring prior to the original expiration date
of the lease with the Existing Tenant is contingent on Landlords ability to
enter into a termination agreement with the Existing Tenant, on terms and
conditions acceptable to Landlord in its sole discretion, pursuant to which the
Existing Tenant would vacate and surrender possession of the JLL Space on or
before January 31, 2009. If Landlord is unable to enter into a termination
agreement with the Existing Tenant, on terms and conditions acceptable to
Landlord in its sole discretion, on or before January 5, 2009, then
Landlord shall so advise Tenant and Landlord shall have the right to terminate
this Ninth Amendment by giving notice to Tenant (unless, prior to the giving of
such notice, Landlord and the Existing Tenant reach such an agreement). Upon
any such termination, this Ninth Amendment shall be void and without further
force or effect, and Landlord shall have no liability hereunder.  7.             Parking.  From and after the Ninth Amendment Effective
Date, Section 10.19 of the Lease shall be amended by, in the first
sentence thereto:  (a)           Replacing
four hundred eleven (411) with five hundred three; and  (b)Replacing
137,037 with 151,129.  8.             Brokers.  Tenant covenants, represents and warrants to
Landlord that Tenant has had no dealings or communications with any broker or
agent (other than Grubb & Ellis Company and Richards Barry Joyce &
Partners) in connection with this Ninth Amendment, and Tenant covenants and
agrees to pay, hold harmless and indemnify the Landlord from and against any
and all cost, expense (including reasonable attorneys fees) or liability for
any compensation, commission or charges to any broker or agent (other than the
foregoing named brokers) claiming through the Tenant with respect hereto.  9.             Exhibits.  Exhibit A-8 attached hereto is
hereby substituted for Exhibit A-6 to the Lease. All references in
the Lease to Exhibit A-1, A-2, A-3, A-4, A-5, A-6
or A-8 shall be replaced by references to Exhibit A-9.  10.           Successors.  This Ninth Amendment shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns, subject to the provisions of the Lease regarding assignment or
other transfers of each partys rights under the Lease.  5


11.           Authority.  Each party represents and warrants to the
other that each person executing this Ninth Amendment on behalf of such party
has the authority to do so and that such execution has fully obligated and
bound such party to all terms and provisions of this Ninth Amendment.  12.           No
Further Amendment.  It is understood
and agreed that all other conditions and terms contained in the Lease not
herein specifically amended shall remain unmodified and in full force and
effect, and the Lease, as modified by this Ninth Amendment, is hereby ratified
and confirmed.  13.           Tenant
Representations. As a material inducement to Landlord entering into this
Ninth Amendment, Tenant represents and certifies to Landlord that as of the
date hereof: (i) the Lease, as modified hereby, and together with that

Tenants knowledge, Landlord is not in default (continuing beyond the

Amendment; and (vi) Tenant is not, and the performance by Tenant of its
obligations hereunder shall not render Tenant, insolvent within the meaning of
the United States Bankruptcy Code, the Internal Revenue Code or any other
applicable law, code or regulation.  14.           Landlord
Representations.  As a material
inducement to Tenant entering into this Ninth Amendment, Landlord represents
and certifies to Tenant that as of the date hereof: (i) the Lease, as
modified hereby, and together with that certain letter dated September 24,
2007 from Ron Friedman to Jack Kerrigan, with the subject line Response to
Specific Security Questions  Hayden Woods Corporate Center, contains the
