ARTICLE II — PREMISES

     2.01 Lease of Premises. Landlord leases the Premises to Tenant, and Tenant leases the Premises from Landlord, upon all of the terms, covenants and conditions contained in this Lease. On the Commencement Date, Landlord shall deliver the Premises to Tenant in the condition described in Section 2.02 of this Lease.

     2.02 Acceptance of Premises. Prior to the Commencement Date, either Tenant or Symons Corporation, a Delaware corporation (“Symons”), and a wholly-owned subsidiary of Tenant, owned, and operated a portion of its business at, the Premises. As a result, Tenant is intimately familiar with the condition of the Premises and, therefore, accepts the Premises in its current “as is”, “where is” condition and “with all faults”, and with full knowledge of all faults and defects, latent or patent, affecting the Premises, without any agreements, representations or obligations on the part of Landlord. Moreover, Tenant acknowledges that, as of the Commencement Date, certain materials that comprise the Building consist of asbestos-containing materials (“ACMs”), which require the maintenance of the ACMs in good condition under an asbestos operation and maintenance program that shall be conducted in accordance with all applicable Environmental Laws (as hereinafter defined; any such program, a “Qualified Asbestos Maintenance Program”). Thus, Tenant hereby forever waives and releases any and all claims, demands and/or rights that Tenant otherwise might have against Landlord and/or any of Landlord’s Parties (as hereinafter defined) due to the presence of such ACMs in and/or at the Building, as of the Commencement Date. Upon taking possession of the Premises, Tenant shall execute Landlord’s then current form of suite acceptance letter, which shall be materially in the form and of the substance contained in the form of suite acceptance letter set forth on Exhibit D attached hereto.

ARTICLE III — TERM

     3.01 Term. Except as otherwise provided in this Lease, the Lease Term shall be for the period described in Section 1.03 of this Lease; provided, however, that Tenant shall have the right, in its sole discretion, to terminate this lease at any time during the initial Lease Term or the Renewal Term (as hereinafter defined), if applicable, upon one hundred eighty (180) days’ prior written notice to Landlord.

     3.02 Renewal.

          (A) Tenant shall have an option (the “Renewal Option”), for all, but not less than all, of the Premises, for a term of one (1) year (the “Renewal Term”), subject to the remaining terms and conditions of this section.

          (B) The Renewal Term, if applicable, automatically shall commence on the day immediately succeeding the Expiration Date and expire on the date that shall be one (1) year after the Expiration Date, unless Tenant delivers to Landlord written notice of its intention to terminate this Lease no later than one hundred eighty (180) days prior to the Expiration Date.

          (C) During the Renewal Term, Tenant shall lease the Premises upon the same terms and conditions as set forth in this Lease, except that the annual Base Rent payable with respect to the Renewal Term shall be $724,627.78 ($60,385.65 per month).

          (D) If the initial Lease Term shall be renewed in accordance with the terms and conditions of this section, Landlord and Tenant shall execute and deliver an amendment to this Lease reflecting the renewal of the Lease Term, upon the terms herein provided, which amendment shall be executed and delivered no later than one hundred fifty (150) days prior to the Expiration Date.

          (E) Tenant agrees to accept the Premises in its then “as-is”, “where-is” physical condition, and “with all faults” on the commencement date of the Renewal Term and Tenant shall not be entitled to any credit or allowance or other economic concession from Landlord for the improvement thereof, or otherwise.

          (F) The Renewal Option automatically shall terminate and become null and void and of no further force or effect, upon the earliest to occur of (i) the early termination of this Lease, (ii) the termination of Tenant’s right to possession of the Premises, (iv) the failure of Tenant to timely or properly exercise the Renewal Option, or otherwise perform any of its obligations, in strict accordance with the terms of this section, (v) the default by Tenant under this Lease, which shall not have been cured prior to the expiration of all applicable notice and cure periods provided in Section 15.01 or (vi) the sublease by Tenant of all or any portion of the Premises or the Transfer (as hereinafter defined) of this Lease, other than to an Affiliate (as hereinafter defined) of Tenant or a Permitted Transferee (as hereinafter defined) in accordance with the express terms and conditions of Section 14.01. Furthermore, notwithstanding anything to the contrary herein contained, the terms and conditions of the Renewal Option outlined in this section are independent of the terms and conditions of any other provisions of this Lease, including, without limitation, Section 22.21 regarding the Right of First Opportunity (as hereinafter defined). Therefore, regardless of whether or not (a) Tenant shall have delivered to Landlord a Tenant’s Right of First Opportunity Notice (as hereinafter defined), (b) Landlord shall have delivered to Tenant a Landlord’s Right of First Opportunity Notice (as hereinafter defined) and/or (c) Landlord and Tenant shall have entered into a Development Lease (as hereinafter defined) or a Development Agreement (as hereinafter defined), Tenant shall have an express duty and obligation to exercise the Renewal Option, if at all, strictly in accordance with the terms and conditions of this section.

          (G) Tenant shall have no further option to renew the Lease Term beyond the expiration of the Renewal Term and Tenant shall be responsible for any brokerage or leasing commissions owed Broker or any other party due to any renewal of the Lease Term by Tenant.

          (H) Notwithstanding anything to the contrary herein contained, upon the commencement of the Renewal Term, if applicable, the terms “Lease Term” and “Term” also shall be deemed to include the Renewal Term.

          (B) “Operating Expenses” means all costs and expenses incurred in the operation, ownership, maintenance, replacement, servicing, compliance and repair of the Premises, which may include, but not be limited to, if applicable: costs for security, utility charges; HVAC service and maintenance contracts costs; costs for repairs to walks, drives, parking areas, or any other improvements on the land; license, permit and inspection fees; grounds care costs, including snow removal, landscaping and lawn, tree and shrubbery care; costs for striping and resurfacing the parking lot; costs for labor, supplies, materials, equipment, tools and insurance premiums connected therewith; all costs of maintenance and redecoration of the exterior of the Building, including repainting and glazing. Notwithstanding anything contained herein to the contrary, the foregoing costs and expenses may be incurred by Tenant at its sole direction and in its sole discretion; provided, however, that, regardless of whether or not Tenant shall incur any or all of the foregoing costs and/or expenses, nothing contained in this Section 4.01(B) shall be deemed or construed as a waiver or release of any of the remaining terms, provisions and/or conditions of this Lease, but rather, throughout the initial Lease Term and the Renewal Term, if applicable, Tenant shall be bound by all of such terms, provisions and conditions and shall be required to satisfy all of Tenant’s other obligations under this Lease in accordance with the express terms and conditions hereof, including, but not limited to, Tenant’s obligation to (i) use, occupy and maintain the Premises in accordance with Applicable Law and the other terms and conditions of Section 6.02, (ii) use and occupy the Premises in accordance with the terms and conditions of Section 6.03, including, without limitation, the maintenance of the ACMs under a Qualified Asbestos Maintenance Program, (iii) maintain the utilities, utility lines and connections, sanitary sewers, storm sewers and other utility lines and connections (collectively, the “Utilities Infrastructure”) in accordance with the applicable terms and conditions of Sections 8.02 and 8.03 and (iv) surrender the Premises to Landlord, upon the expiration or earlier termination of the initial Lease Term or the Renewal Term, if applicable, in accordance with the terms and conditions of this Lease, including, without limitation, Sections 9.03 and 21.01.

          (C) “Insurance Expenses” means all costs for premiums for all insurance required, pursuant to the provisions of this Lease, to be procured and maintained by Tenant in connection with or relating to the Premises.

     4.02 Payment. Notwithstanding anything contained herein to the contrary, all Property Taxes, Operating Expenses and Insurance Expenses (collectively, the “Tax, Operating and Insurance Expenses”), which relate to all or any portion of the Lease Term and/or the Renewal Term, if applicable, shall be the sole and exclusive obligation and responsibility of Tenant. Accordingly, Tenant shall pay, as and when due, the Tax, Operating and Insurance Expenses, as follows:

          (A) Tenant shall pay all Property Taxes payable as to the Premises and attributable to all or any portion of a calendar year that shall comprise all or a portion of the Lease Term and/or the Renewal Term, if applicable, directly to the relevant taxing authority having jurisdiction over the Premises.

          In furtherance of the foregoing, and in recognition of the fact that, at the very least, general real estate taxes payable as to the Premises shall be imposed by Cook County, Illinois (the “County”), which collects such taxes in arrears, Tenant acknowledges and agrees that all or a portion of the Property Taxes payable as to the Premises and attributable to all or some portion of the final calendar year that shall comprise all or a portion of the Lease Term or the Renewal Term, if applicable, will not be collected by the County, until after the expiration or earlier termination of the Lease Term or the Renewal Term, if applicable.

          As a result of the foregoing, on or prior to the first day of the thirteenth (13^th) month of the Lease Term (or the first month of the Renewal Term, if applicable), and on the first day of each month thereafter, throughout the balance of the Lease Term, Tenant shall pay to Landlord, as Rent, in addition to all other sums due and payable by Tenant to Landlord hereunder, an amount equal to one-twelfth (1/12th) of the estimated amount of Property Taxes that shall be payable as to the Premises and attributable to all or some portion of the final calendar year that shall comprise all or a portion of the Lease Term and/or the Renewal Term, if applicable, which estimated amount shall be based on the bill issued by the County for collection of the Property Taxes payable as to the Premises and attributable to the calendar year immediately preceding such final calendar year. Once the County shall have issued the actual bill for the Property Taxes as to the Premises and attributable to such final calendar year, if the total amount of the actual Property Taxes payable as to the Premises and attributable to such final calendar year shall be more than the estimated payments for such calendar year made by Tenant, then Tenant shall pay the deficiency to Landlord, within thirty (30) days of receipt by Tenant of a written demand for such payment. On the other hand, if the actual Property Taxes payable as to the Premises and attributable to such final calendar year shall be less than the estimated payments for such calendar year made by Tenant, then any excess shall be paid to Tenant, or retained by Landlord and credited towards any amounts then due and payable by Tenant to Landlord, pursuant to the remaining provisions of this Lease, if applicable. The termination of this Lease shall not affect the obligations of Landlord and Tenant pursuant to this Section 4.02(A) to be performed after such termination.

          (B) Tenant shall pay all Operating Expenses incurred as to the Premises and attributable to all or any portion of the Lease Term and/or the Renewal Term, if applicable, directly to the provider of the product(s) and/or services(s), for which any and all of the Operating Expenses shall have been incurred. Notwithstanding anything contained herein to the contrary, Tenant shall not be deemed in default of its obligations under this Lease solely due to a failure to timely pay any such Operating Expenses, so long as such failure shall not (i) result in a Lien against or on the Premises, subject Tenant’s right to contest the same in accordance with the terms and conditions of Section 9.02, or (ii) otherwise constitute a default by Tenant under this Lease for any reason not solely due to such failure, including, without limitation, a default by Tenant as to its obligation to (a) use, occupy and maintain the Premises in accordance with Applicable Law and the other terms and conditions of Section 6.02, (b) use and occupy the Premises in accordance with the terms and conditions of Section 6.03, including, without limitation, the maintenance of the ACMs under a Qualified Asbestos Maintenance Program, and/or (c) maintain the Utilities Infrastructure in accordance with the applicable terms and conditions of this Lease, including, but not limited to, Sections 8.02 and 8.03.

          (C) Tenant shall pay all Insurance Expenses incurred as to the Premises and attributable to all or any portion of the Lease Term and/or the Renewal Term, if applicable, directly to the provider of the product(s) and/or services(s), for which any and all of the Insurance Expenses shall have been incurred.

          (D) Notwithstanding anything contained herein to the contrary, Tenant, in connection with its use of the Premises, shall not cause Landlord and/or any of Landlord’s Parties to have any obligation, liability and/or responsibility for any Operating Expenses and/or Insurance Expenses attributable to any product(s) and/or services(s), for which any and all of the Operating Expenses shall have been incurred, whether as to the period prior to the Commencement Date, the Lease Term, the Renewal Term, if applicable, and/or the period following the expiration or earlier termination of this Lease, but rather, the payment of all of such Operating Expenses and Insurance Expenses shall be the exclusive obligation, liability and responsibility of Tenant, which obligations, liabilities and responsibilities shall survive the expiration or earlier termination of this Lease.

     4.03 Base Rent. During the Lease Term, Tenant shall pay to Landlord for the Premises as part of Rent, the annual Base Rent in monthly installments as described in Section 1.06. Upon execution hereof, Tenant shall pay Landlord Base Rent attributable to the first calendar month of the Lease Term. Thereafter, the annual amount of Base Rent due Landlord shall be payable in equal monthly installments due in advance on the first day of each calendar month without notice, demand, abatement, deduction or offset for any reason, except as specifically provided to the contrary in Article XI. If the Commencement Date is other than the first day of a calendar month, any prepaid Base Rent for the first month of the Term shall be prorated in the proportion that the number of days this Lease is in effect during such partial month bears to the total number of days in such month.

     4.04 Late Charge; Interest. In addition to any other rights and remedies of Landlord for Tenant’s default hereunder, if Landlord shall receive Rent after five (5) days after the date the payment thereof is due, Tenant shall pay to Landlord a late charge of Five Hundred and No/100 Dollars ($500.00) to cover administrative costs, so long as Landlord shall have received such Rent on or prior to fifteen (15) days after the date such payment is due; provided, however, that, if Landlord shall not have received such Rent as of sixteen (16) days after the date such payment is due, Tenant shall pay to Landlord (A) a late charge equal to five percent (5%) of the overdue amount, or Five Hundred and No/100 Dollars ($500.00), whichever is greater, to cover additional administrative costs; and (B) interest on the delinquent amounts at a default rate of interest equal to the lesser of the maximum rate permitted by law, if any, or the Prime Rate, plus four percent (4%) per annum, from the date such payment is due to the date paid. For purposes hereof, the “Prime Rate” shall mean the rate of interest per annum publicly

announced by LaSalle Bank National Association, Chicago, Illinois, as its prime lending rate or reference rate as in effect from time to time (the Prime Rate is not necessarily the best or lowest rate of interest offered by said bank).

     4.05 Additional Rent. For purposes of this Lease, all amounts payable by Tenant to Landlord pursuant to this Lease, whether denominated as such, shall constitute additional rental hereunder. All additional rental, together with the Base Rent, shall sometimes be referred to in this Lease as “Rent”. All Rent shall be paid to Landlord, without notice, demand, abatement, deduction or offset for any reason, , except as specifically provided to the contrary in Article XI, in lawful money of the United States at such place as Landlord may designate from time to time by written notice given to Tenant.

ARTICLE XI — DAMAGE OR DESTRUCTION

     11.01 Total Destruction. Tenant shall give immediate written notice to Landlord of any damage or destruction caused to the Premises by fire or other casualty (“Tenant’s Casualty Notice”). If the Building shall be totally destroyed, this Lease automatically shall terminate as of the date of such destruction, subject to the terms and conditions of Section 11.02(A) as to Tenant’s obligation to repair the damage to or destruction of, as the case may be, the Utilities Infrastructure, if any.

     11.02 Partial Destruction.

          (A) If the Premises shall be partially damaged by any casualty, promptly upon delivery of Tenant’s Casualty Notice to Landlord, Tenant shall proceed with reasonable diligence and in good faith to repair any damage or destruction to the portion of the Premises that consists of the Utilities Infrastructure, if any, and prosecute the same to completion as soon as reasonably practicable. The foregoing obligation of Tenant to repair such damage or destruction as to the portion of the Premises that consists of the Utilities Infrastructure, if any, shall consist of restoring such Utilities Infrastructure to the condition in which the same existed prior to such damage or destruction. If Tenant shall have failed to complete the required repairs to the Utilities Infrastructure on or prior to the date that shall be one hundred twenty (120) days after the date of the damage or destruction (the “Restoration Date”), Landlord may elect to terminate this Lease by delivering written notice to Tenant of its intention to do so no later than fifteen (15) days after the Restoration Date; provided, however, that, if Tenant shall have failed to complete the required repairs to the Utilities Infrastructure as of the date on which the initial Lease Term or the Renewal Term, if applicable, shall have expired or otherwise been terminated, pursuant to the remaining provisions of this Lease, including, without limitation, the applicable provisions of this Article XI, then Tenant’s obligation to so repair the Utilities Infrastructure shall survive the expiration or earlier termination of the initial Lease Term or the Renewal Term, if applicable, and Landlord shall be entitled to the portion of the casualty insurance proceeds to which Tenant otherwise would have been entitled as shall be necessary, in the opinion of Landlord, to complete such repairs, which proceeds Tenant shall assign to Landlord on or prior to the expiration or earlier termination of the initial Lease Term or the Renewal Term, if applicable.

          (B) In addition, within thirty (30) days after delivery of Tenant’s Casualty Notice, Tenant shall give written notice to Landlord (“Tenant’s Repair Notice”) as to whether or not Tenant, in its sole discretion, intends to repair all or any portion of the damage or destruction to the Building, if any, and, if so, whether or not, in the opinion of Tenant, such repairs can be made on or prior to the Restoration Date.

          (C) If Tenant’s Repair Notice shall (i) not have been delivered to Landlord within said 30-day period, or (ii) state that (a) Tenant does not intend to repair all or any portion of such damage or destruction to the Building, or (b) such repairs to the Building cannot, in the opinion of Tenant, be made on or prior to the Restoration Date, then either Landlord or Tenant may elect to terminate this Lease by delivering written notice of such party’s intention to so terminate this Lease to the other party, within fifteen (15) days after the date of Tenant’s Repair Notice or the date on which Tenant’s Repair Notice was due, if no such notice shall have been delivered.

          (D) If neither Landlord not Tenant shall have exercised its right to terminate this Lease in accordance with the terms and conditions of the immediately preceding subsection, Tenant shall (i) proceed with reasonable diligence and in good faith to repair the damage or destruction to the Building to the extent and in the manner as shall be determined by Tenant in its sole discretion, and (ii) prosecute the same to completion as soon as reasonably practicable, whereupon this Lease shall continue in full force and effect, without abatement of any Base Rent or other Rent otherwise due and payable hereunder with respect to the entire Premises throughout the balance of the initial Lease Term and the Renewal Term, if applicable; provided, however, that, notwithstanding anything contained herein to the contrary, (a) the foregoing obligation of Tenant to repair such damage or destruction to the Building, at a minimum, shall consist of making such repairs as shall be necessary to enable Tenant to satisfy all of Tenant’s other obligations under this Lease in accordance with the express terms and conditions hereof, including, but not limited to, Tenant’s obligation to (1) use, occupy and maintain the Premises in accordance with Applicable Law and the other terms and conditions of Section 6.02, and (2) use and occupy the Premises in accordance with the terms and conditions of Section 6.03, including, without limitation, the maintenance of the ACMs in good condition under a Qualified Asbestos Maintenance Program, and (b) if Tenant shall have failed to complete the required repairs to the Building on

or prior to date that shall be one hundred twenty (120) days after the Restoration Date, Landlord may elect to terminate this Lease by delivering written notice to Tenant of its intention to do so no later than seventy-five (75) days after the Restoration Date.

     11.03 Waiver. The provisions contained in this Lease shall supersede any contrary laws (whether statutory, common law or otherwise) now or hereafter in effect relating to damage, destruction, self-help and/or termination.

ARTICLE XII — CONDEMNATION

     12.01 Taking. If the entire Premises, or so much of the Premises as shall render the balance unusable by Tenant, shall be taken by condemnation or in any other manner for any public or quasi-public purpose (collectively “Condemnation”), then this Lease shall terminate on the earlier of the date that title or possession to the Premises shall have been taken by the condemning authority.

     12.02 Award. In the event of any Condemnation, the entire award for such taking shall belong to Landlord, free of any claim by Tenant; provided, however, that Landlord shall not restrict Tenant or interfere with Tenant in the filing of its own claim, so long as Tenant’s claim shall not diminish the size of the Landlord’s award.

     12.03 Temporary Taking. No temporary taking of the Premises shall entitle Tenant to any abatement of the Rent payable to Landlord under this Lease, unless (A) Tenant shall have elected, by written notice to Landlord, to terminate this Lease, upon the occurrence of any such temporary taking, or (B) solely as a result of such temporary taking, (i) the entire Premises shall be unusable by Tenant for Tenant’s Permitted Use and (ii) Tenant shall not use any portion of the Premises for Tenant’s Permitted Use, or otherwise, whereupon Tenant shall be entitled to an abatement of the Base Rent that otherwise would have been payable hereunder, until Tenant no longer would be prevented, solely as a result of such temporary taking, from being able to use any portion of the Premises for Tenant’s Permitted Use; provided, however, that, if, as a result of such temporary taking, the entire Premises shall be unusable by Tenant for Tenants’ Permitted Use and Tenant shall not use any portion of the Premises for a period of one hundred eighty (180) consecutive days, then Landlord may elect to terminate this Lease by delivering written notice to Tenant of its intention to do so.

ARTICLE XIII — RESERVED

ARTICLE XIV — ASSIGNMENT AND SUBLETTING

     14.01 Restriction.

          (A) Tenant shall not, either voluntarily or by operation of law, assign, encumber, or otherwise transfer this Lease or any interest herein, or sublet the Premises or any part thereof, or permit the Premises to be occupied by anyone other than Tenant or Tenant’s employees (any such assignment, encumbrance, subletting, occupation or transfer hereinafter shall be referred to as a “Transfer”). For purposes of this Lease, the term “Transfer” shall also include, if Tenant is a closely held corporation (i.e. whose stock is not publicly held and not traded through an exchange or over the counter), or a limited liability company, the dissolution, merger, consolidation, division, liquidation or other reorganization of Tenant, or within a twelve month period: (i) the sale or other transfer of more than an aggregate of 50% of the voting securities of Tenant (other than to immediate family members by reason of gift or death) or (ii) the sale, mortgage, hypothecation or pledge of more than an aggregate of 50% of Tenant’s net worth. A Transfer or other action in violation of the foregoing, at Landlord’s option, shall be void and/or shall constitute a material breach of this Lease, which, without any notice and/or opportunity to cure the same, shall entitle Landlord to exercise any and all rights and/or remedies available to Landlord, upon the occurrence of an Event of Default (as hereinafter defined), pursuant to this Lease, at law and/or in equity, including, without limitation, the right to terminate this Lease, effective as of the date of any such Transfer. A Transfer or other action in violation of the foregoing, at Landlord’s option, shall be void and/or shall constitute a material breach of this Lease. Notwithstanding anything contained herein to the contrary, Tenant shall have the right to assign this Lease to an Affiliate of Tenant or a Permitted Transferee, upon at least twenty (20) days’ prior written notice to Landlord, whereupon, if such assignment shall be to a Permitted Transferee, Tenant, and its officers, employees and shareholders, shall be relieved of any further liabilities or obligations whatsoever under this Lease, with respect to the period from and after the date of such assignment, and Landlord agrees to hold such Permitted Transferee solely responsible for any and all liabilities and obligations under this Lease with respect to the period from and after the date of such assignment, so long as Landlord first shall have received a written assumption of such obligations from such Permitted Transferee, as the case may be; provided, however, that, all sums or other economic consideration, if any, received by Tenant in connection with any such assignment, whether denominated as rental or otherwise, which exceed in the aggregate, the total sum that Tenant is obligated to pay Landlord under this Lease shall be paid to Landlord promptly after receipt, without affecting or reducing any other obligation of Tenant hereunder.

          (B) For all purposes of this Lease, the term “Affiliate” shall mean any corporation or other entity controlling, controlled by, or under common control with (directly or indirectly) Tenant or Landlord, as the case may be. The term “control”, as used herein, shall mean the power to direct or cause the direction of the management and policies of the controlled entity through the ownership of more than fifty percent (50%) of the voting securities in such controlled entity. The term “Permitted Transferee” shall mean any entity that shall acquire, (i) Tenant, by merger, consolidation or other corporate action, or (ii) all or substantially all of Tenant’s assets, so long as the surviving entity or purchaser of such assets, as the case may be, shall have a “net worth” equal to or greater than the net worth of Tenant as of the proposed date of such corporate action or sale, as the case may be. Notwithstanding anything contained in this Article XIV to the contrary, Tenant agrees not to enter into any agreement for use, occupancy or utilization of the Premises, which provides for rental or other payment based in whole or in part on the net income or profits derived by any person from the Premises (other than an amount based on a fixed percentage(s) of receipts or sales), and that any such purported agreement shall be absolutely void and ineffective.

ARTICLE XV — EVENTS OF DEFAULT AND REMEDIES

     15.01 Events of Default by Tenant. Upon the occurrence of any one or more of the following events (the “Events of Default,” any one an “Event of Default”), the party not in default shall have the right to exercise any rights or remedies

9

available in this Lease, at law and/or in equity. Any notice and cure period provided for herein shall be in lieu of, and not in addition to, any notice required under any Applicable Law now or hereafter in effect requiring that notice of default be given prior to the commencement of an unlawful detainer or other legal proceeding. Events of Default shall be, as follows:

          (A) Tenant’s failure to pay within five (5) days of the date due any Rent payable hereunder.

          (B) Failure by Tenant to perform any other of the terms, covenants or conditions contained in this Lease, if not remedied within thirty (30) days after receipt of written notice thereof; provided, however, that, if the nature of Tenant’s obligation is such that more than thirty (30) days would be required for performance, Tenant shall not be in default, if Tenant commences performance within such thirty (30) day period and thereafter diligently pursues same to completion; provided, however, in any event, such performance must be completed within one hundred eighty (180) days after receipt of the original written notice of such failure to perform.

          (C) Tenant shall become bankrupt or insolvent, or file any debtor proceedings, or files, pursuant to any statute a petition in bankruptcy or insolvency or for reorganization, or files a petition for the appointment of a receiver or trustee for all or substantially all of Tenant’s assets, and such petition or appointment shall not have been set aside within sixty (60) days from the date of such petition or appointment, or, if Tenant shall make an assignment for the benefit of creditors, or petition for or enter into an arrangement for any of the foregoing.

          (D) Tenant vacates, abandons or fails to operate in the Premises for a period of thirty (30) days or allows its leasehold estate to be taken under any writ of execution; provided, however, that Tenant shall be entitled to challenge any such writ, so long as the same does not result in a Lien against or on the Premises, subject Tenant’s right to contest the same in accordance with the terms and conditions of Section 9.02.

     15.02 Landlord’s Option to Terminate upon Tenant Default. In addition to its other remedies, Landlord, upon an Event of Default by Tenant, shall have the immediate right, to terminate and cancel this Lease and/or reenter and remove all persons and properties from the Premises and dispose of such property as it deems fit, all without being guilty of trespass or being liable for any damages caused thereby. In the event of an elected termination by Landlord, whether before or after reentry, Landlord may recover from Tenant damages, including, without limitation, the costs of recovering the Premises, and Tenant shall remain liable to Landlord for the total Rent as would have been payable by Tenant hereunder for the remainder of the Lease Term, less the reasonable rental value of the Premises for the remainder of the Lease Term. In determining the Rent that would be payable by Tenant after a default, the Rent for each year of the un-expired Lease Term shall be equal to the Rent payable by Tenant for the last year of the Lease Term prior to the applicable default. If any rent owing hereunder shall be collected by or through an attorney, Tenant agrees to pay Landlord’s reasonable attorneys’ fees to the extent allowed by Applicable Law.

     15.03 Mitigation of Damages. Whether Landlord shall terminate this Lease and/or Tenant’s right to possession of the Premises, Landlord shall have no obligation to mitigate Landlord’s damages, except as required by Applicable Law.

     15.04 Right of Landlord to Perform. If Tenant shall fail to perform any required act under this Lease, Landlord, without obligation, may do so without waiving Tenant’s obligations under this Lease. In such event, Tenant shall pay to Landlord, as Rent, any sums incurred by Landlord, together with an administrative charge equal to five percent (5%) thereof.

     15.05 Non-Waiver. No acceptance by Landlord of a lesser sum than the Rent then due shall be deemed to be other than on account of the earliest installment of such Rent due, and no endorsement or statement on any check or any letter accompanying any check or payment shall be deemed an accord and satisfaction, and Landlord may accept such check or payment, without prejudice to Landlord’s right to recover the balance of such installment and/or pursue any other remedy in this Lease, at law and/or in equity provided. Moreover, the acceptance by Landlord of any Rent, while Tenant shall be in default hereunder, shall not serve or operate as a waiver of any rights and/or remedies to which Landlord otherwise would be entitled hereunder, at law and/or in equity, as a result of such default. The delivery of keys to Landlord or its agent or employee shall not operate as a termination of this Lease or as a surrender of the Premises, unless so acknowledged in writing by Landlord.

     15.06 Cumulative Remedies. The specific remedies to which Landlord may resort under the terms hereof are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions hereof. In addition to the other remedies provided herein, Landlord shall be entitled to a restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions hereof and/or to a decree compelling specific performance of any such covenants, conditions or provisions.

     15.07 Landlord’s Default. Landlord shall not be in default under this Lease, unless Landlord fails to perform its obligations hereunder within a reasonable time, but in no event later than thirty (30) days after written notice by Tenant to Landlord and to Mortgagee whose name and address shall have been furnished to Tenant in writing and specifying how Landlord has failed to perform such obligations and the act required to cure the same; provided, however, that if the nature of Landlord’s obligation is such that more than thirty (30) days would be required for performance, Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion; provided, however, in any event, such performance must be completed within one hundred eighty (180) days after receipt of the original written notice of such failure to perform. In no event shall Tenant have the right to seek damages as a result of Landlord’s default and Tenant’s remedies shall be limited to the termination of this Lease and/or an injunction.

ARTICLE XVI — SUBORDINATION AND ATTORNMENT

     16.01 Subordination. This Lease, and the rights of Tenant hereunder, shall be subject and subordinate to the interests of (A) all present and future ground leases and master leases of all or any part of the Premises; (B) present and future mortgages and deeds of trust encumbering all or any part of the Premises; (C) all past and future advances made under any such mortgages or deeds of trust; and (D) all renewals, modifications, replacements and extensions of any such ground leases, master

leases, mortgages and deeds of trust; provided, however, that any lessor under any such ground lease or master lease or any mortgagee or beneficiary under any such mortgage or deed of trust (any such lessor, mortgagee or beneficiary is herein referred to as a “Mortgagee”) may elect, by written notice given to Tenant, to have this Lease made superior in whole or in part to any such ground lease, master lease, mortgage or deed of trust. Within ten (10) days of written request from Landlord, Tenant shall execute, acknowledge and deliver any instruments reasonably requested by Landlord or any such Mortgagee to affect the purposes of this Section 16.01, including, without limitation, a Subordination, Attornment and Non-disturbance Agreement/Estoppel Agreement substantially similar to the form attached hereto as Exhibit C. Any obligations of Mortgagee shall be non-recourse as to any assets of such Mortgagee other than its interest in the Premises.

     16.02 Attornment. If requested to do so, Tenant shall attorn to, and recognize as Tenant’s landlord hereunder, any Mortgagee or other purchaser or person taking title to the Premises by reason of the termination of any superior lease or the foreclosure of any superior mortgage or deed of trust or sale of property or any other reason, and Tenant, within ten (10) days after demand, shall execute and deliver any documents reasonably requested by any such person to evidence the foregoing.

     16.03 Mortgage and Ground Lessor Notice. Tenant shall give any Mortgagee or ground lessor, by certified mail, a copy of any notice of default served upon Landlord by Tenant, provided that prior to such notice Tenant has been notified in writing of the address of such Mortgagee. If Landlord shall fail to cure such default within thirty (30) days after such notice to Landlord (or if such default cannot be cured within that time, then such additional time as may be reasonably necessary), then the Mortgagee shall have an additional thirty (30) days within which to cure such default (or, if such default cannot be cured within that time, then such additional time as may be reasonably necessary).

ARTICLE XVII — RESERVED

ARTICLE XVIII — ESTOPPEL CERTIFICATES

     18.01 Estoppel Certificates. Tenant shall, from time to time, within five (5) days of written request from Landlord deliver to Landlord and any other party designated by Landlord, an estoppel certificate substantially similar to the form attached hereto as Exhibit C, acknowledged and executed by Tenant and any Guarantor of this Lease. Any such certificate given to any Mortgagee or prospective Mortgagee may contain certifications of such other matters, customarily required by such Mortgagee. If Tenant does not deliver to Landlord the certificate as required herein, then Landlord is granted an irrevocable power-of-attorney, coupled with an interest, to execute such certificate on Tenant’s behalf, which statement shall be binding on Tenant (and such grant shall not be in limitation of Landlord’s other remedies for such failure by Tenant).

ARTICLE XIX — ENTRY BY LANDLORD

     19.01 Entry by Landlord. Landlord, and Landlord’s contractors, agents and consultants, may enter the Premises during normal business hours and upon not less than 48 hours prior notice (which notice may be oral), other than in the case of any emergency in which case any such party may enter the Premises at any time, to: inspect the same; exhibit the same to prospective purchasers, prospective mortgagees or tenants; determine whether Tenant is complying with all of its obligations under this Lease, including, without limitation, the Handling of Hazardous Materials by Tenant; post notices of non-responsibility or to make repairs or improvements in or to the Premises. Tenant hereby waives any claim for damages for any injury to, or interference with, Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises, or any other loss occasioned by such entry or repair or service work, which Landlord deems to be reasonably necessary; provided, however, that Landlord shall use its reasonable efforts to prevent any such entry from adversely interfering with Tenant’s use of the Premises in any material respect, except in the event of an emergency. Landlord may require Tenant to provide a key with which to unlock one or more doors that, collectively, would enable Landlord to access the entire Premises (excluding Tenant’s safes and similar areas designated by Tenant in writing in advance), and Landlord may obtain entry to the Premises, and any entry shall not under any circumstances be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises or an eviction, actual or constructive, of Tenant from any part of the Premises. Such entry by Landlord shall not act as a termination of this Lease.

ARTICLE XX — LANDLORD’S LEASE UNDERTAKINGS; TRANSFER OF LANDLORD’S INTEREST

     20.01 Landlord’s Lease Undertakings. Notwithstanding anything to the contrary contained in this Lease or in any exhibits, riders or addenda hereto attached (collectively the “Lease Documents”), it is expressly understood and agreed that: (A) the recourse of Tenant against Landlord with respect to the alleged breach by Landlord of a representation, warranty, covenant, undertaking or agreement, if any, contained in any of the Lease Documents, or otherwise, arising out of this transaction and/or Tenant’s use of the Premises (collectively, “Landlord’s Lease Undertakings”), shall extend only to Landlord’s interest in the real estate of which the Premises demised under the Lease Documents are a part (“Landlord’s Real Estate”), and not to any other assets of Landlord’s Parties; and (B) except to the extent of Landlord’s interest in Landlord’s Real Estate, no personal liability or personal responsibility of any sort with respect to any of Landlord’s Lease Undertakings, and/or any alleged breach thereof, is assumed by, or at any time shall be asserted or enforceable against, Landlord’s Parties.

     20.02 Transfer of Landlord’s Interest. Landlord shall have the right to sell, transfer or assign the Premises, or any part thereof, or Landlord’s interest in this Lease, in which event Landlord shall be automatically freed and relieved from all applicable liability with respect to performance of any covenant or obligation on the part of Landlord. Any Security Deposits or advance rents held by Landlord shall be turned over to the successor, and said successor shall expressly assume, subject to the limitations of this Article XX, all of the terms, covenants and conditions of this Lease to be performed by Landlord arising from and after the date of such sale, transfer or assignment, it being intended hereby that the covenants and obligations contained in this Lease on the part of Landlord, subject to all the provisions of this Article XX, shall be binding on Landlord, its successors and assigns, only during their respective periods of ownership.

ARTICLE XXI — SURRENDER; HOLDOVER TENANCY

     21.01 Condition of Premises and Removal of Property. At the expiration or earlier termination of this Lease or the termination of Tenant’s right to possession of the Premises, Tenant shall surrender possession of the Premises (A) with the

11

Utilities Infrastructure in the condition required under Sections 8.02 and 8.03, and (B) otherwise in the condition required under Section 9.03, none of which Tenant understands to mean that Tenant shall be relieved of performing, in accordance with the applicable terms and conditions of this Lease, any of its other obligations hereunder during the initial Lease Term and/or the Renewal Term, if applicable, including, without limitation, those relating to the use, occupancy, maintenance, repair and/or replacement of the Premises. The cost of any repair or restoration of the Premises required to satisfy Tenant’s obligation to surrender of possession of the Premises in the condition required by this Section 21.01 shall be borne by Tenant; provided, however, that, if Tenant shall fail to promptly perform such repairs or restoration, Landlord, without obligation, may perform the same and all costs thereof incurred by Landlord shall be reimbursed by Tenant promptly upon demand.

     21.02 Abandoned Property. If Tenant shall fail to remove any items from the Premises, as required under Sections 9.03 and 21.01, Landlord may do so at Tenant’s expense. All of such property removed from the Premises by Landlord hereunder may be handled, discarded or stored by Landlord at Tenant’s expense, and Landlord shall in no event be responsible for the value, preservation and/or safekeeping thereof. All such property, at Landlord’s option, shall be conclusively deemed to have been conveyed by Tenant to Landlord, as if by bill of sale, without payment by Landlord.

     21.03 Holdover Tenancy. Regardless of whether or not (A) Tenant shall have delivered to Landlord a Tenant’s Right of First Opportunity Notice, (B) Landlord shall have delivered to Tenant a Landlord’s Right of First Opportunity Notice and/or (C) Landlord and Tenant shall have entered into a Development Lease or a Development Agreement, Tenant shall have an express duty and obligation to surrender the entire Premises to Landlord, upon the expiration or earlier termination of the Lease Term or the Renewal Term, if applicable. If, however, Tenant shall hold possession of the Premises after the expiration or termination of the Lease Term or the Renewal Term, if applicable, in violation of the foregoing express duty and obligation of Tenant to so surrender the Premises to Landlord, Tenant shall become a tenant at sufferance, upon all of the terms contained herein, except as to the term of this Lease and Rent. During such holdover period, Tenant shall pay to Landlord a monthly rental equivalent to twice the Rent payable during the last month of the Lease Term. The monthly rent payable for such holdover period in no event shall be construed as a penalty or as liquidated damages for such retention of possession. Without limiting the foregoing, Tenant shall indemnify, protect, defend and hold harmless Landlord’s Parties, from and against any and all claims, liabilities, actions, losses, damages (including, without limitation, direct, indirect, incidental and consequential) and expenses (including, without limitation, court costs and reasonable attorneys’ fees) asserted against or sustained by Landlord’s Parties and arising by reason of such retention of possession, which obligations shall survive the expiration or termination of the Lease Term.

     22.16 Tenant Operations Inquiry. As a material inducement to Landlord to enter into this Lease, Tenant has completed the attached Exhibit B.

Any notice shall be deemed to have been given and served when delivered personally or, otherwise, at the time the same shall have been posted.

     22.21 Right of First Opportunity for New Development.

          (A) If, upon the expiration or earlier termination of the Lease Term or the Renewal Term, if applicable, Tenant shall desire not to relocate the existing operations of Tenant currently being conducted at the Premises (collectively, “Tenant’s Operations”), from the Premises to an existing building(s), but rather, shall desire to either enter into a Development Lease or a Development Agreement, then Landlord shall have a right of first opportunity (the “Right of First Opportunity”), throughout the Right of First Opportunity Period (as hereinafter defined), to be the party with whom Tenant shall negotiate the terms and conditions of such Development Lease or Development Agreement, as the case may be, subject to the remaining terms and conditions of this section.

          (B) For purposes hereof, (i) the term “Development Lease” shall mean a lease, between Tenant, or one of its subsidiaries or affiliates, and a third-party, for a “build-to-suit” development of a site and a building(s) to be the location of at least some or all of Tenant’s Operations, and (ii) the term “Development Agreement” shall mean an agreement, between Tenant, or one of its subsidiaries or affiliates, and a third-party, pursuant to which such third-party would acquire and develop a site, construct a building(s) thereon, and either sell or lease the same to Tenant upon the completion thereof, to be the location of at least some or all of Tenant’s Operations.

          (C) If, during the Lease Term or the Renewal Term, if applicable, Tenant shall desire to solicit a third-party to negotiate the terms and conditions of a Development Lease and/or a Development Agreement, then Tenant shall deliver to Landlord written notice (“Tenant’s Right of First Opportunity Notice”) thereof, which shall contain such information as would be reasonably necessary for Landlord to determine whether or not Landlord would want to exercise the Right of First Opportunity.

          (D) Within five (5) business days after receipt of Tenant’s Right of First Opportunity Notice, if applicable, Landlord shall deliver to Tenant written notice (“Landlord’s Right of First Opportunity Notice”) of Landlord’s election to exercise the Right of First Opportunity (if Landlord shall not so deliver Landlord’s Right of First Opportunity Notice, Landlord will be deemed to have waived the Right of First Opportunity).

          (E) If Landlord shall have so delivered Landlords’ Right of First Opportunity Notice, then Tenant shall negotiate with Landlord, exclusively and in good faith, and for a reasonable period of time, the terms and conditions of a

13

Development Lease and/or a Development Agreement, as the case may be, which shall be mutually acceptable to Landlord and Tenant; provided, however that, in no event shall such reasonable period of time extend beyond the period that shall commence on the date that Tenant shall have received Landlord’s Right of First Opportunity Notice and end on the date that shall be sixty (60) days thereafter (the “Right of First Opportunity Period”); and, further, provided, however, that Tenant shall retain the right during the Right of First Opportunity Period to negotiate with other parties regarding the terms and conditions of a Development Lease and/or a Development Agreement, as the case may be, solely for the purpose of determining market valuations as to the terms and conditions of the Development Lease and/or the Development Agreement, as the case may be.

          (F) If, prior to 5:00 p.m. (Chicago, Illinois time) on the last day of the Right of First Opportunity Period, Landlord and Tenant shall have failed to agree in writing on the terms and conditions of a Development Lease or a Development Agreement, as the case may be, then the Right of First Opportunity no longer shall apply and Tenant shall have the right to negotiate the terms and conditions of a Development Lease and/or a Development Agreement, as the case may be, with any third-party.

          (G) The Right of First Opportunity, as well as any Landlord’s Right of First Opportunity Notice that may have been delivered to Tenant, automatically shall terminate and become null and void and of no further force or effect, upon the failure of Landlord to timely or properly exercise the Right of First Opportunity, or otherwise perform any of its obligations under, and in accordance with, the provisions of this section.

          (H) If Tenant shall default under this section, Landlord shall have the right to exercise any and all remedies available to Landlord in equity, including, without limitation, specific performance of Tenant’s obligations under this section or injunctive relief.

     22.22 Letter of Intent. Notwithstanding anything to the contrary contained herein or in the Letter of Intent regarding (A) the sale of the Premises by Tenant to Landlord and (B) this Lease, which was executed and delivered by Seller and Purchaser as of March 3, 2005 (the “LOI”), except to the extent that, pursuant to the terms, provisions and/or conditions of the LOI, any of such terms, provisions and/or conditions are expressly intended to survive the expiration or earlier termination thereof, (i) this Lease shall supersede the LOI, (ii) from and after the Effective Date, if not previously rendered null and void and of no further force or effect by the provisions of the Agreement of Sale entered into by Tenant and Landlord with respect to the sale of the Premises by Tenant to Landlord, the LOI shall be null and void and of no further force or effect, and (iii) in the event of any conflict between any term, provision or condition contained herein, and any term, provision or condition contained in the LOI, the terms, provisions and conditions of this Lease shall govern and control.
