Amendment, Second Amendment, Third Amendment, Fourth Amendment, Fifth Amendment,
Sixth Amendment, Seventh Amendment, Eighth Amendment and Ninth Amendment are
collectively referred to herein as the “Lease”) with respect to premises more
particularly described therein (“Premises”) in the building located at 5550
Prairie Stone Parkway, Hoffman Estates, Illinois commonly known as Two Park
Center (the “Building”).
B.    Landlord is the successor to Original Landlord.
C.    As of the date hereof, the Premises contain 73,586 rentable square feet,
consisting of 48,993 rentable square feet on the third floor of the Building,
11,092 rentable square feet on the first floor of the Building (defined in the
Eighth Amendment as the “Reduced Premises”), and Suite 200 at the Building
containing approximately 13,501 rentable square feet (defined in the Sixth
Amendment as the “Second Floor Expansion Space”). The Term of the Lease is
currently scheduled to expire December 31, 2012 (“Expiration Date”).
D.    Landlord and Tenant now desire to extend the Term of the Lease for one (1)
year.
NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties agree as follows:
1.    The recitals set forth above are hereby incorporated into and made a
material part of this Tenth Amendment. Capitalized terms used but not otherwise
defined herein shall have the same meaning ascribed to them in the Lease.
2.    The Term of the Lease with respect to the entire 73,586 rentable square
feet in the Premises is hereby extended through December 31, 2013.
3.    Tenant shall continue to pay and perform its obligations under the Lease
through the Expiration Date, as further extended and amended by this Tenth
Amendment. During 2013, Tenant shall pay Base Rent for the Premises in the
amount of Seventy Thousand Five Hundred Nineteen and 92/100 Dollars ($70,519.92)

the Lease. Tenant shall

continue to pay Tenant's Proportionate Share of Building Operating Expenses and
Tenant's Proportionate Share of Taxes through the extended Term.
4.    Upon prior written notice to Tenant, Landlord shall continue to have the
right to show the Second Floor Expansion Space to prospective tenants, provided
that Landlord shall use commercially reasonable efforts to minimize disruption
with Tenant's operations in the Premises. Landlord continues to reserve the
right to substitute for the Second Floor Expansion Space other premises at the
Building (herein referred to as the "Relocation Premises"), provided: (i) the
Relocation Premises shall be similar to the Second Floor Expansion Space in
square footage area, (ii) Landlord shall give Tenant at least ninety (90) days'
written notice before making such change, and the parties shall execute an
amendment to the Lease confirming the change within thirty (30) days after
either party shall request the same; and (iii) Landlord shall pay directly all
of the out of pocket expenses and costs associated with Landlord's relocation of
the Second Floor Expansion Space to the Relocation Premises at Landlord's sole
cost. In addition, at Landlord's sole cost, Landlord shall be responsible for
reinstalling the Tenant's personal property and equipment in the Relocation
Premises, and improving the Relocation Premises so that they are substantially
similar to the Second Floor Expansion Space (including, but not limited to,
cabling and network systems), and, (iv) such move shall be made during evenings,
weekends, or otherwise so as to incur the least inconvenience to Tenant. Tenant
waives any claim for abatement of Rent or loss of profits due to such
relocation. Tenant shall cooperate with Landlord in connection with any
relocation, including, without limitation, providing timely responses to any
requests for review and approval of proposed plans for tenant improvements to
the Relocation Premises. Upon the date of such relocation, the Second Floor
Expansion Space shall be removed from the Premises, the Relocation Premises
shall become and be deemed part of the Premises hereunder and all the terms,
covenants and conditions of this Lease shall be applicable to the Relocation
Premises. After such relocation, Landlord and Tenant, within thirty (30) days
after the written request of either Landlord or Tenant, shall execute a written
amendment to the Lease confirming the foregoing relocation.
5.     Tenant hereby accepts the Premises in its current "as is" condition.
Tenant acknowledges that Landlord has made no agreement to alter, remodel,
decorate, clean or improve the Premises or Building in connection with this
Tenth Amendment.
6.    Neither Landlord nor Tenant has dealt with any broker or agent in
connection with the negotiation or execution of this Tenth Amendment, other than
Cushman & Wakefield and CB Richard Ellis (collectively, the “Brokers”), whose
commissions shall be paid by Landlord in accordance with their separate
agreement. Tenant and Landlord shall each indemnify the other against all costs,
expenses, attorneys' fees, and other liability for commissions or other
compensation claimed by any broker or agent claiming the same by, through, or
under the indemnifying party other than the Brokers.

7.    This Tenth Amendment sets forth the entire agreement with respect to the
matters set forth herein. There have been no additional oral or written
representations or agreements. In the case of any inconsistency between the
provisions of this Tenth Amendment and the Lease, the provisions of this Tenth
Amendment shall control to the extent necessary to resolve any inconsistency.
8.    If any provision contained in this Tenth Amendment is rendered invalid or
unenforceable by a court of competent jurisdiction, it shall not affect the
remaining provisions of this Tenth Amendment and the Lease, which shall remain
in full force and effect.
9.    This Tenth Amendment shall not be binding until executed and delivered by
both parties.

one of which shall be an original, but all of which together shall be one and
the same instrument.

confirmed, and shall remain in full force and effect.
