2. GRANT AND ACCEPTANCE OF LEASE.

Landlord hereby leases the Premises to Tenant and Tenant hereby accepts and leases the Premises from Landlord to have and to hold during the Term, subject to the terms and conditions of this Lease.

3. RENT.

Base Rent, Additional Rent, Additional Rent Estimate and all other amounts becoming due from Tenant to Landlord hereunder (collectively “Rent”) shall be paid in lawful money of the United States to Landlord at the following address: 135 South LaSalle Street, Dept. 5956, Chicago, Illinois 60674-5956, or such other address as Landlord shall designate in writing to Tenant from time to time, without any demand and without any reduction, abatement, counterclaim, deduction or set-off whatsoever, except as expressly provided herein, at the times and in the manner hereinafter provided. Unpaid Rent shall bear interest at the Default Rate from the date due until paid. The payment of Rent hereunder is independent of each and every other covenant and agreement contained in this Lease. The first monthly installment of Base Rent payable under Section 4 hereof and of Additional Rent payable under Section 5 hereof shall be paid in advance on the date of Tenant’s execution of this Lease and applied to the first installments of Base Rent and Additional Rent coming due under this Lease.

4. BASE RENT.

Tenant shall pay Base Rent (as set forth in the Basic Provisions) to Landlord in equal monthly installments (herein called “Monthly Base Rent”), in advance on the Commencement Date and on or before the first day of each and every calendar month during the Term. If the Term shall begin on any day other than the first day of a calendar month or end on any day other than the last day of a calendar month, then the Monthly Base Rent for any partial calendar month within the Term shall be prorated on a per diem basis. Notwithstanding the foregoing, commencing on the Commencement Date, Monthly Base Rent shall be abated in the aggregate amount of Two Hundred Fifty Thousand Dollars ($250,000); provided that upon the occurrence of a Default by Tenant, which results in the termination of this Lease or Tenant’s right to possession of the Premises hereunder, Tenant’s right to any to-be-credited abatement shall cease.

5. ADDITIONAL RENT.

In addition to paying the Base Rent, Tenant shall also pay as additional rent the amounts (collectively “Additional Rent”) determined to be Tax Adjustment and Expense Adjustment in accordance with this Section 5:

(a) Computation of Additional Rent. Tenant shall pay as Additional Rent for each Calculation Year the following amounts:

(i) Tenant’s Proportionate Share of Taxes for such Calculation Year (the “Tax Adjustment”); plus

(ii) Tenant’s Proportionate Share of Expenses for such Calculation Year (the “Expense Adjustment”).

(b) Payments of Additional Rent; Additional Rent Estimate; Projections. Tenant shall pay Additional Rent to Landlord in the manner hereinafter provided. The aggregate of payments required to be made by Tenant on account of Additional Rent for any Calculation Year until actual Additional Rent is determined is herein called “Additional Rent Estimate.”

(i) Landlord may, at any time and from time to time prior to the first Calculation Date and during the Term (but not more than twice during any Calculation Year), deliver to Tenant a written notice or notices (“Projection Notice”) setting forth:

(A) Landlord’s reasonable and good faith estimates, forecasts or projections (collectively, the “Projections”) of any or all of Taxes and Expenses for such Calculation Year, and

(B) Tenant’s Additional Rent Estimate (setting forth the Expense Adjustment component and Tax Adjustment component separately) based upon the Projections, being the Tenant’s Proportionate Share of the Projections.

(ii) On or before the first (1st) day of the next calendar month following Landlord’s service of a Projection Notice, and on or before the first day of each month thereafter, Tenant shall pay to Landlord one-twelfth (1/12) of the Additional Rent Estimate shown in the Projection Notice. Within thirty (30) days following Landlord’s service of a Projection Notice, to bring Tenant’s payments of Additional Rent Estimate current, Tenant shall also pay Landlord the amount set forth in the Projection Notice, which shall equal the Additional Rent Estimate shown in the Projection Notice less (A) any previous payments on account of Additional Rent Estimate made for such Calculation Year, and (B) total monthly installments on account of Additional Rent Estimate not yet due and payable for the remainder of such Calculation Year. Until such time as Landlord furnishes a Projection Notice for a Calculation Year, Tenant shall pay to Landlord a monthly installment of Additional Rent Estimate on the first day of each month equal to the greater of the latest monthly installment of Additional Rent Estimate or one-twelfth (1/12) of Tenant’s latest determined Additional Rent.

(c) Readjustments.

(i) Within ninety (90) days following the end of each Calculation Year and after Landlord shall have determined the amount of Expenses to be used in calculating the Expense Adjustment for such Calculation Year, Landlord shall notify Tenant in writing (any such notice of Expenses and Expense Adjustment herein called “Landlord’s Expense Statement”) of such Expenses and Tenant’s Expense Adjustment for such Calculation Year. If the Expense Adjustment owed for such Calculation Year exceeds the Expense Adjustment component of the Additional Rent Estimate paid by Tenant during such Calculation Year, then Tenant shall, within thirty (30) days after the date of Landlord’s Expense Statement, pay to Landlord an amount equal to the excess of the Expense Adjustment over the Expense Adjustment component of the Additional Rent Estimate paid by Tenant during such Calculation Year. If the Expense Adjustment component of the Additional Rent Estimate paid by Tenant during such Calculation Year exceeds the Expense Adjustment owed for such Calculation Year, then Landlord shall credit such excess to Additional Rent payable after the date of Landlord’s Expense Statement, or may, at its option, credit such excess to any Rent theretofore due and owing, until such excess has been exhausted. If this Lease shall expire or be terminated prior to full application of such excess, Landlord shall pay to Tenant, within thirty (30) days after the date of such expiration or termination, the balance thereof not theretofore applied against Rent and not reasonably required for payment of Rent for the Calculation Year in which this Lease expires, subject to Tenant’s obligations under Section 5(e) hereof, provided Tenant shall have vacated the Premises and otherwise surrendered the Premises to Landlord in accordance with this Lease and Tenant is not then in uncured default under this Lease following written notice thereof.

(ii) Within ninety (90) days following the end of each Calculation Year and after Landlord shall have determined the actual amount of Taxes to be used in calculating the Tax Adjustment for such Calculation Year, Landlord shall notify Tenant in writing (any such notice of Taxes and Tax Adjustment herein called “Landlord’s Tax

Statement”) of such Taxes for such Calculation Year. If the Tax Adjustment owed for such Calculation Year exceeds the Tax Adjustment component of the Additional Rent Estimate paid by Tenant during such Calculation Year, then Tenant shall, within thirty (30) days after the date of Landlord’s Tax Statement, pay to Landlord an amount equal to the excess of the Tax Adjustment over the Tax Adjustment component of the Additional Rent Estimate paid by Tenant during such Calculation Year. If the Tax Adjustment component of the Additional Rent Estimate paid by Tenant during such Calculation Year exceeds the Tax Adjustment owed for such Calculation Year, then Landlord shall credit such excess to Additional Rent payable after the date of Landlord’s Tax Statement, or may, at its option, credit such excess to any Rent theretofore due and owing, until such excess has been exhausted. If this Lease shall expire or be terminated prior to full application of such excess, Landlord shall pay to Tenant, within thirty (30) days after the date of such expiration or termination, the balance thereof not theretofore applied against Rent and not reasonably required for payment of Rent for the Calculation Year in which this Lease expires, subject to Tenant’s obligations under Section 5(e) hereof, provided Tenant shall have vacated the Premises and otherwise surrendered the Premises to Landlord in accordance with this Lease and Tenant is not then in uncured default under this Lease following written notice thereof.

(d) Books and Records. Landlord shall maintain books and records showing Taxes and Expenses in accordance with sound accounting and management practices. Tenant and/or its representative (which representative shall be a nationally recognized independent certified public accountant licensed to do business in the State of Illinois) shall have the right to examine such books and records showing Taxes and Expenses upon reasonable prior notice and during normal business hours at any time within one hundred eighty (180) days following Tenant’s receipt of Landlord’s Expense Statement (as it relates to an examination of Expenses) or Landlord’s Tax Statement (as it relates to an examination of Taxes) provided for in Section 5(c); provided however that (a) if any auditor or other representative retained by Tenant is or will be compensated, in whole or in part, on a “contingent fee” basis, or (b) in the event Landlord has caused Landlord’s Expense Statement and/or Landlord’s Tax Statement, as the case may be, to be audited by an independent public accounting firm with a national reputation, then Tenant shall not have the right to cause an audit of Landlord’s books and records regarding Taxes and Expenses, as applicable. Unless Tenant shall take written exception to any item of Taxes or Expenses, specifying in detail the reasons for such exception as to a particular item within one hundred eighty (180) days after Tenant’s receipt of Landlord’s Expense Statement or Landlord’s Tax Statement (as the case may be), or in the event Landlord causes Landlord’s Expense Statement and/or Landlord’s Tax Statement to be audited as provided above, Landlord’s Expense Statement and Landlord’s Tax Statement, as applicable, shall be considered as final and accepted by Tenant. Notwithstanding any exception made by Tenant, Tenant shall pay Landlord the full amount of its Additional Rent Estimate and its Additional Rent as determined by Landlord, subject to readjustment at such time as any such exception may be resolved in favor of Tenant.

(e) Proration and Survival. With respect to any Calculation Year which does not fall entirely within the Term, Tenant shall be obligated to pay as Additional Rent for such Calculation Year only a pro rata share of Additional Rent as hereinabove determined, based upon the number of days of the Term falling within the Calculation Year. Following expiration or termination of this Lease, Tenant shall pay any Additional Rent due to Landlord within fifteen (15) days after the date of Landlord’s Expense Statement or Landlord’s Tax Statement (as the case may be) sent to Tenant. Without limiting other obligations of Tenant which survive the expiration or termination of this Lease, the obligations of Tenant to pay Additional Rent provided for in this Section 5 shall survive the expiration or earlier termination of this Lease. No interest or penalties shall accrue on any amounts which Landlord is obligated to credit or pay to Tenant by reason of this Section 5.

(f) No Decrease in Base Rent. In no event shall any Additional Rent result in a decrease of the Base Rent payable hereunder.

(g) No Representation or Warranty. Tenant acknowledges that neither Landlord, nor any of its respective members, agents or employees, has made or does hereby make any representation or warranty whatsoever to Tenant as to the amount of Taxes, Expenses, Tax Adjustment or Expense Adjustment or any component thereof which may become payable during the Term.

6. USE OF PREMISES.

(a) Use. Tenant shall use and occupy the Premises as set forth in Section 1(y) hereof only and for no other use or purpose. Tenant shall comply with all rules and regulations made and adopted in accordance herewith by Landlord from time to time for the Building relating to Tenant’s use of the Premises and the Building.

(b) Compliance with Requirements. Tenant shall comply with all applicable Laws (hereinafter defined) now or hereafter in force, and with all applicable insurance underwriters regulations and other requirements, respecting all matters of occupancy, condition or maintenance of the Premises, whether any of the foregoing shall be directed to Tenant or Landlord and whether imposed on the owner or occupant of the Premises (except to the extent such compliance falls within Landlord’s obligations under Sections 9(c), 17 and 18 to maintain, repair and/or restore the Premises in which event Landlord shall so comply). “Laws” means all statutes, laws, ordinances, codes, rules and regulations, orders and directions of public officials or other acts having the force or effect of law, of all federal, state, county, municipal and other agencies, authorities or bodies having jurisdiction over the Premises. Tenant shall not make or permit any use of the Premises or the Building, or do or permit to be done anything in or upon the Premises or the Building, or bring or keep anything in the Premises or the Building, which directly or indirectly is forbidden by any of the foregoing or which may be dangerous to persons or property, or which may invalidate or increase the rate of insurance on the Building, its appurtenances, contents or operations, or which would tend to create or continue a nuisance or which is contrary to or prohibited by the terms and conditions of this Lease.

7. LEASEHOLD IMPROVEMENTS.

Tenant shall be responsible for and shall pay all costs incurred in connection with the installation of telephone or other communication wiring, equipment and systems in or exclusively serving the Premises, including, without limitation, any hook-up, access and maintenance fees related to the installation of such wiring, equipment and systems in or exclusively serving the Premises and the commencement of service therein, and the maintenance thereafter of such wiring, equipment and systems; and there shall be included in Expenses for the Building all installation, hook-up or maintenance costs incurred by Landlord in connection with telephone or other communication wiring, equipment and systems in the Building which are not allocable to any individual users of such service but are allocable to the Building generally. If Tenant fails to maintain all telephone or other communication wiring, equipment or systems in or exclusively serving the Premises and such failure affects or interferes with the operation or maintenance of any other telephone or other communication wiring, equipment or systems in the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises forthwith and perform such repairs, restorations or alterations as Landlord deems necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s costs in connection therewith and Landlord shall have no liability to Tenant by reason thereof). Upon the Expiration Date or the earlier termination of this Lease or of Tenant’s right to possession of the Premises,

Tenant agrees to remove all telephone or other communication wiring, equipment and systems installed by Tenant for and during Tenant’s occupancy, which Landlord has requested Tenant to remove in writing at the time Landlord approves the installation thereof (provided that with respect to any portion thereof installed without Landlord’s approval, such request may be made at any time on or before the Expiration Date or the earlier termination of this Lease or of Tenant’s right to possession of the Premises), and to repair any and all damage to the Development caused by such removal, all at Tenant’s sole cost and expense. Tenant agrees that, subject to the provisions of Section 16(d), neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s employees, agents customers or invitees or anyone claiming through, by or under Tenant, for any damages, injuries, losses, expenses, claims or causes of action because of any interruption, diminution, delay or discontinuance at any time for any reason in the furnishing of any telephone or other communication service to the Premises and the Building.

(d) Extra or Additional Services. Tenant may request Landlord to provide services which are extra or additional services to those described in Section 8(a), by delivery to Landlord of an advance written request therefor. Landlord shall use all commercially reasonable efforts to furnish the Premises with after-hours air-conditioning and heat as so requested by Tenant from time to time provided that Landlord’s obligation to furnish same on Saturdays (other than 8:00 A.M. to 1:00 P.M.), Sundays or Holidays shall be conditioned on Landlord having received written request therefor from Tenant at least two (2) business days prior to the date for which such service is requested. If Landlord shall agree to so provide any such services which are extra or in addition to those services described in Section 8(a), Tenant shall pay for any such extra or additional services so provided by Landlord at Landlord’s established rates therefor from time to time, or if there are no established rates, then at the rate of 115% of the cost of providing such service, or as otherwise agreed by Landlord and Tenant. As of the date of this Lease, the established rate for after-hours air-conditioning and heat is $120.00 per hour with a four (4) hour minimum. All charges for any such extra or additional services so provided by Landlord shall be deemed to be additional Rent hereunder and shall be due and payable within ten (10) days after Tenant receives Landlord’s bill therefor, or in installments as may be designated by Landlord to Tenant in writing. If Tenant fails to pay when due Landlord’s proper charges for any such extra or additional services, Landlord shall have the right, in addition to all other rights and remedies available to Landlord, to discontinue furnishing any such extra or additional services for which Tenant has failed to pay. If Landlord discontinues any such extra or additional services as provided in this Section 8(d), no such discontinuance shall be deemed an eviction or disturbance of Tenant’s use of the Premises or render Landlord liable for damages or relieve Tenant from performance of Tenant’s obligations under this Lease.

(e) Holidays. For purposes of this Section 8, “Holidays” means New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day and any other day recognized as a holiday by the service unions representing workers providing services to the Building or customarily designated as a holiday by landlords operating first-class office buildings in downtown Chicago, Illinois.

(f) Interruption of Services. Tenant agrees that neither Landlord, nor any of Landlord’s constituent members, nor any of their respective agents, partners or employees, shall be liable for damage or injury to person, property or business or for loss or interruption of business, or for any other matter, in the event there is any failure, delay, interruption or diminution in furnishing any service. No such failure, delay, interruption or diminution shall be deemed to constitute an eviction or disturbance of Tenant’s use or possession of the Premises, in whole or in part, actual or constructive, nor entitle Tenant to any claim for set-off, abatement or reduction of Rent, nor render Landlord liable for damages, nor relieve Tenant from the performance of or affect any of Tenant’s obligations under this Lease. However, Landlord shall use commercially reasonable efforts to minimize any such failure, delay, interruption or diminution. Notwithstanding the foregoing, in the event any such failure, delay, interruption or diminution of services or utilities furnished by Landlord is due to a cause within Landlord’s reasonable control and causes the Premises to be untenantable, and as a result thereof, Tenant in fact ceases to use the Premises for a period in excess of five (5) consecutive days, then commencing on the sixth (6th) consecutive day of such untenantability and non-use, Rent payable by Tenant shall be abated until the earliest to occur of (a) the date such failure, delay,

interruption or diminution is remedied, (b) the date the Premises are again tenantable or (c) the date Tenant resumes use of the Premises.

(g) Tenant’s Cooperation. Tenant agrees to cooperate fully with Landlord, at all times, in abiding by all reasonable non-discriminatory regulations and requirements which Landlord may prescribe for the proper functioning and protection of all utilities and services reasonably necessary for the operation of the Premises or the Development. Landlord and its contractors shall have access to any and all mechanical installations in the Premises upon reasonable prior oral or written notice to Tenant (except in case of emergency) and, except in case of emergency, subject to Tenant’s reasonable requirements regarding security and protection of Tenant’s confidential information, and Tenant agrees that there shall be no construction of partitions or other obstructions which might interfere with the moving of the servicing equipment of Landlord to or from the enclosures containing said installations. Tenant further agrees that neither Tenant nor its employees, agents, licensees, invitees or contractors shall at any time tamper with, adjust or otherwise in any manner adversely affect Landlord’s mechanical installations in the Premises or the Project.

(h) Supplemental Heating or Cooling. Whenever, in Landlord’s reasonable judgment, Tenant’s use or occupation of the Premises, including lighting, personnel, heat generating machines or equipment, or airborne emissions of smoke or other particulates, individually or cumulatively, causes the design loads for the system providing heat and air-cooling to be exceeded, or otherwise affects adversely the temperature, humidity or air quality otherwise maintained by the heating, ventilating and air handling or conditioning system in the Premises or the Building, Landlord may, but shall not be obligated to, temper such excess loads by installing supplementary heating or air handling or conditioning units in the Premises or elsewhere where necessary. In such event, the cost of such units and the expense of installation, including, without limitation, the cost of preparing working drawings and specifications, plus fifteen percent (15%) of such cost as an overhead and supervision fee, shall be paid by Tenant as additional Rent within ten (10) days after Landlord’s demand therefor. Alternatively, Landlord may require Tenant to install such supplementary heating or air handling or conditioning units at Tenant’s sole expense. Landlord may operate and maintain any such supplementary units, but shall have no continuing obligation to do so or liability in connection therewith. The expense resulting from the operation and maintenance of any such supplementary heating or air handling or conditioning units, including utility charges, charges for condenser water, repair costs, labor costs and rent for space occupied by any supplementary heating or air handling or conditioning units installed in Rentable Area outside the Premises, shall be paid by Tenant to Landlord as additional rent at rates fixed by Landlord. Alternatively, Landlord may require Tenant to operate and maintain any such supplementary units, also at Tenant’s sole expense.

9. CONDITION AND CARE OF PREMISES.

(a) Condition of Premises. Tenant’s taking possession of the Premises or any portion thereof shall be conclusive evidence against Tenant that such portion of the Premises was then in good order and satisfactory condition, subject to Landlord’s obligations under this Lease and the Workletter. Tenant acknowledges that, except as otherwise expressly set forth in this Lease or the Workletter, the Premises shall be accepted by Tenant in their “as-is” condition, and that no promise by or on behalf of Landlord, any of Landlord’s Constituent Members, the leasing agent of the Project or any of their respective agents, partners or employees, to alter, remodel, improve, repair, decorate or clean the Premises has been made to or relied upon by Tenant, and that no representation respecting the condition of the Premises or the Project by or on behalf of Landlord, its constituent members, or any of their respective agents, partners or employees has been made to or relied upon by Tenant, except as provided below and in the Workletter, and further provided that during the three (3) year period commencing on the Commencement Date, Landlord shall reimburse Tenant for alterations, improvements and/or refurbishment (collectively, the “Refurbishment”) of the Original Premises, in an aggregate amount not to exceed $116,888.00 (the “Refurbishment Allowance”). The Refurbishment Allowance shall be payable to Tenant within thirty (30) days after presentation to Landlord of paid invoices, contractor’s sworn statements, final waivers of lien and such other documentation as may reasonably required by Landlord showing that the Refurbishment has been completed and fully paid for in accordance with the requirements of Section 14 hereof, provided that any undisbursed portion of the Refurbishment Allowance for which Tenant has not requested reimbursement and submitted the aforesaid documentation within the aforesaid 3-year period, time being of essence,

shall be deemed forfeited by Tenant and retained by Landlord without any claim thereon by Tenant.

(b) Tenant’s Repairs. Subject to the provisions regarding fire and other casualty losses set forth in Section 17 hereof, Tenant, at its expense, shall (i) keep the Premises (including all Landlord’s Work and Landlord’s Additional Work (except for defects in materials and/or workmanship therein for a period of one (1) year following the Turnover Date as defined in Exhibit B) and all Tenant Alterations) in good order, repair and condition at all times during the Term, and (ii) promptly and adequately repair all damage to the Premises, including damage to interior windows and to any portion of the Building air conditioning, heating, electrical and plumbing systems which run through the Premises and which serve the Premises, caused by Tenant or its contractors, agents, employees or invitees. Tenant shall give prompt notice to Landlord of any material repair, maintenance or replacement items required under this Section 9(b). All work with respect to any such maintenance, repair or replacement shall be performed within a reasonable period after the need for such action arises and shall be subject to the provisions of Section 14 hereof. In the event Tenant fails to make any required repairs and such failure continues for thirty (30) days after written notice to Tenant (or in case of emergency, such failure is not remedied immediately after oral or written notice to Tenant), Landlord may, in its sole discretion, elect to effect such repairs whether or not Tenant would otherwise be prepared to do so, and, in such case, Tenant shall pay Landlord the cost thereof plus a coordination and management fee equal to fifteen percent (15%) of such cost, upon Landlord’s written demand.

(c) Landlord’s Repairs. Subject to the provisions regarding fire and other casualty losses set forth in Section 17 hereof, Landlord shall (i) keep the foundations, roofs, exterior walls, and the structural elements of the Building, and the common areas in the Building, exclusive of the Premises and other tenant spaces occupied by or under the control of tenants, in good order, repair and condition at all times during the Term, (ii) keep in good order, condition and repair all outside windows of the Premises and the electrical, plumbing, heating, ventilating and air conditioning systems servicing the Premises (other than as set forth in Section 9(b) above), and (iii) repair any defects in materials and/or workmanship in Landlord’s Work and/or Landlord’s Additional Work for a period of one (1) year following the Turnover Date (as defined in Exhibit B). Notwithstanding the foregoing, (A) Landlord shall not be responsible for the maintenance or repair of any floor or wall coverings in the Premises or any of such systems which are located within the Premises and are supplemental or special to the Building’s standard systems; and (B) the cost of performing any of said maintenance or repairs, whether to the Premises or to the Building, caused by the negligence of Tenant, its employees, agents, servants, licensees, subtenants, contractors or invitees, shall be paid by Tenant immediately upon Landlord’s demand therefor. Upon reasonable prior oral or written notice (except in the case of an emergency, where no such notice shall be required), and except in emergency, subject to Tenant’s reasonable requirements regarding security and protection of Tenant’s confidential information and so long as Landlord uses good faith efforts to maintain reasonable access to the Premises and to minimize unreasonable interference with the conduct of Tenant’s business, Landlord may, but shall not be required to, enter the Premises at all reasonable times to make repairs, alterations, improvements and additions to the Premises or to the Building or to any equipment located in the Building as Landlord shall desire or deem necessary or as Landlord may be required to make by governmental authority or court order or decree.

(d) No Rights to Light, Air or View. This Lease does not grant any rights to light, air or view over or about the real property of Landlord or any other real property. Landlord specifically excepts and reserves to itself all rights to and the use of any roofs, the exterior portions of the Premises, the land, improvements and air and other rights below the improved floor level of the Premises, the improvements and air and other rights above the improved ceiling of Premises, the improvements and air and other rights located outside the demising walls of the Premises and such areas within the Premises as are required for installation of utility lines and other installations required to serve the Building or any occupants of the Building, and Landlord specifically reserves to itself the right to use, maintain and repair same, and no rights with respect thereto are conferred upon Tenant, unless otherwise specifically provided herein.

(e) Hazardous Substances. Tenant shall comply, at its sole expense, with all Laws relating to the protection of public health, safety and welfare and with all environmental Laws in the use, occupancy and operation of the Premises, provided that Tenant shall not be liable under this provision for pre-existing conditions in the Building or the Premises. Tenant agrees that no

Hazardous Substances (as hereinafter defined) shall be used, located, stored or processed on the Premises or be brought into the Building by Tenant, and no Hazardous Substances will be released or discharged from the Premises (including, but not limited to, ground water contamination). The term “Hazardous Substances” shall mean and include all hazardous and toxic substances, waste or materials, any pollutant or contaminant, including, without limitation, PCB’s, asbestos and raw materials that include hazardous constituents or any other similar substances or materials that are now or hereafter included under or regulated by any environmental Laws or that would pose a health, safety or environmental hazard. In the event that Tenant is notified of any investigation or violation of any environmental Law arising from Tenant’s activities at the Premises, Tenant shall immediately deliver to Landlord a copy of such notice. In such event or in the event Landlord reasonably believes that a violation of environmental Law exists, Landlord may conduct such tests and studies relating to compliance by Tenant with environmental Laws or the alleged presence of Hazardous Substances upon the Premises as Landlord deems desirable, all of which shall be completed at Tenant’s expense. Landlord’s inspection and testing rights are for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed any responsibility to Tenant or any other party for compliance with environmental Laws, as a result of the exercise, or non-exercise of such rights. Tenant shall indemnify, defend, protect and hold harmless Landlord, its constituent members, Lincoln Property Company Commercial, Inc., Fulcrum Operating Company LLC, Landlord’s managing agent, and their respective officers, directors, members, partners, agents, employees, successors and assigns (collectively, the “Landlord Parties”), from and against any and all loss, claim, expense, liability and cost (including attorneys’ fees) arising out of or in any way related to the presence of any Hazardous Substance introduced to the Premises during the Term by Tenant, its agents, employees, contractors, affiliates, subtenants, assignees, customers and/or invitees.

(f) Americans with Disabilities Act. Landlord and Tenant acknowledge that the Americans With Disabilities Act of 1990 (42 U.S.C §12101 et seq.) and regulations and guidelines promulgated thereunder, as all of the same may be amended and supplemented from time to time (collectively referred to herein as the “ADA”) establish requirements for business operations, accessibility and barrier removal, and that such requirements may or may not apply to the Premises and the Building depending on, among other things: (1) whether Tenant’s business is deemed a “public accommodation” or “commercial facility,” (2) whether such requirements are “readily achievable,” and (3) whether a given alteration affects a primary function area or triggers “path of travel” requirements. The parties hereby agree that: (a) Landlord shall be responsible for ADA Title III compliance in the common areas of the Building, except as provided below, and with respect to Landlord’s Work and Landlord’s Additional Work (b) Tenant shall be responsible for ADA Title III compliance in the Premises, including any leasehold improvements or other work to be performed in the Premises under or in connection with this Lease (other than Landlord’s Work and Landlord’s Additional Work), (c) Landlord may perform, or require that Tenant perform, and Tenant shall be responsible for the cost of, ADA Title III “path of travel” requirements triggered by alterations in the Premises, and (d) Landlord may perform, or require Tenant to perform, and Tenant shall be responsible for the cost of, ADA Title III compliance in the common areas of the Building necessitated by the Building being deemed to be a “public accommodation” instead of a “commercial facility” as a result of Tenant’s use of the Premises. Tenant shall be solely responsible for requirements under Title I of the ADA relating to Tenant’s employees.

10. SURRENDER OF PREMISES.

(a) Surrender. Upon the termination of this Lease by lapse of time or otherwise or upon the earlier termination of Tenant’s right of possession, Tenant shall surrender possession of the Premises to Landlord and deliver all keys, computer cards or codes and other entry devices to the Premises to Landlord and make known to Landlord the combinations of all locks of vaults then remaining in the Premises, and shall, subject to the following subparagraphs, return the Premises and all equipment and fixtures of Landlord therein to Landlord in as good condition as when Tenant originally took possession, except for ordinary wear and tear, and except for loss or damage by fire or other insured casualty or condemnation (which Tenant is not required to restore pursuant to Section 17 of this Lease), failing which Landlord may, following written notice thereof to Tenant and Tenant’s failure to and cure within five (5) days thereafter, restore

the Premises and such equipment and fixtures to such condition, and Tenant shall pay the cost thereof to Landlord on demand.

(b) Ownership of Improvements. All installations, additions, partitions, hardware, fixtures and improvements, temporary or permanent (including Landlord’s Work, Landlord’s Additional Work and Tenant Alterations), except movable furniture and equipment and other personal property or trade fixtures belonging to Tenant, in or upon the Premises, whether placed there by Tenant or Landlord, shall, upon the termination of this Lease by lapse of time or otherwise or upon the earlier termination of Tenant’s right of possession, become Landlord’s property and shall remain upon the Premises, all without compensation, allowance or credit to Tenant; provided, however, that if at the time Landlord consents to Tenant’s installation of Tenant Alterations, or prior to the commencement of Landlord’s Work, Landlord’s Additional Work or other installations, additions, partitions, hardware, fixtures and improvements or at any other time prior to termination of this Lease or Tenant’s right to possession, Landlord notifies Tenant in writing that Landlord requires removal of the same upon termination, then Tenant, at Tenant’s sole cost and expense, upon termination of this Lease by lapse of time or otherwise or upon the earlier termination of Tenant’s right of possession, shall promptly remove such designated items, and Tenant shall thereafter repair any damage to the Premises or the Project caused by such removal, failing which Landlord may remove the same and repair the Premises or the Project, as the case may be, and Tenant shall pay the cost thereof to Landlord on written demand. Without limitation of the foregoing, if any of the Tenant Alterations, Landlord’s Additional Work or Landlord’s Work involved the lowering of ceilings, raising of floors then Tenant, at Landlord’s request, shall also be obligated to return such surfaces to their condition prior to the commencement of this Lease. Tenant’s failure to perform the work described in the preceding sentence on or before the expiration or earlier termination of this Lease or Tenant’s right of possession hereunder, shall, without limitation on other rights or remedies available to Landlord, give rise to the right of Landlord to perform such work, and Tenant shall pay the costs thereof to Landlord on written demand.

(c) Removal of Personal Property. Upon the termination of this Lease by lapse of time or otherwise or upon the earlier termination of Tenant’s right of possession, Tenant shall remove from the Premises Tenant’s furniture, machinery, safes and other items of movable personal property of every kind and description and Tenant’s trade fixtures, and Tenant shall restore any damage to the Premises or the Project caused thereby (such removal and restoration to be performed prior to the expiration of the Term or earlier termination of this Lease or Tenant’s right of possession), failing which Landlord may do so and thereupon the provisions of Section 19(f) shall apply.

(d) Survival. Without limitation of any other obligations of Tenant which shall survive the expiration or termination of this Lease, all obligations of Tenant under this Section 10 shall survive the expiration or earlier termination of this Lease.

11. HOLDING OVER.

If Tenant retains possession of the Premises or any part thereof after the termination of this Lease by lapse of time or otherwise or after the earlier termination of Tenant’s right of possession, Tenant shall pay to Landlord as Rent during such holdover period an amount equal to 150% of the Rent (based on the Base Rent plus the most current Additional Rent Estimate owed by Tenant during the most recent year for the entire Premises), on a per diem basis. In addition to and without limiting any other rights and remedies which Landlord may have on account of such holding over by Tenant, Tenant shall indemnify Landlord from and against any and all direct and consequential damages suffered by Landlord on account of such holding over by Tenant, including any damages and claims by tenants entitled to future possession. No occupancy by Tenant after the expiration or other termination of this Lease shall be construed to extend the Term. The provisions of this Section 11 shall not be deemed to limit or constitute a waiver of any rights or remedies of Landlord as provided herein or at law or equity.

Tenant agrees to indemnify, defend by counsel reasonably acceptable to Landlord and hold Landlord and the other Landlord Parties, and the Project, harmless of, from and against any and all losses, damages, liabilities, claims, liens, costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses, arising in connection with any Tenant Alterations. All Tenant Alterations done by Tenant or its contractors, including work done pursuant to Section 9, shall be performed in a first class workerlike manner using only good grades of materials which conform to Building standard materials and shall comply with all insurance requirements of Landlord and all Laws. Within thirty (30) days after substantial completion of any Tenant Alterations by or on behalf of Tenant for which a building permit has been or is required to be issued, Tenant shall furnish to Landlord “as built” drawings of such Tenant Alterations. All Tenant Alterations shall be performed in accordance with Landlord’s standard construction rules and regulations for the Building. In no event shall any supervision or right to supervise by Landlord, nor shall any approvals given by Landlord hereunder, constitute any warranty by Landlord to Tenant of the adequacy of the design,

workmanship or quality of the Tenant Alterations, or impose any liability upon Landlord in connection with the performance of such work.

15. ASSIGNMENT AND SUBLETTING.

(a) Prohibitions. Except as otherwise expressly provided in this Section 15, Tenant shall not, either prior or subsequent to the commencement of the Term, (i) assign, transfer, mortgage, pledge, hypothecate or encumber or subject to or permit to exist upon or be subjected to any lien or charge, this Lease or any interest under it, (ii) allow to exist or occur any transfer of or lien upon this Lease or Tenant’s interest herein by operation of law, (iii) sublet the Premises or any part thereof, or (iv) permit the use or occupancy of the Premises or any part thereof for any purpose not provided for under Section 6 of this Lease or by anyone other than Tenant and Tenant’s employees. Landlord has the absolute right to withhold its consent to any of such acts without giving any reason whatsoever, except as herein expressly provided to the contrary in Sections 15(d) and 15(h). In no event shall this Lease be assigned or assignable by voluntary or involuntary bankruptcy proceedings or otherwise, except as provided by law, and in no event shall this Lease or any rights or privileges hereunder be an asset of Tenant under any bankruptcy, insolvency or reorganization proceedings, except as provided by law. Any of the foregoing performed or attempted in violation of the provisions of this Section shall be null and void.

(b) Continuing Liability. No assignment, subletting, use, occupancy, transfer or encumbrance by Tenant shall operate to relieve Tenant from any covenant, liability or obligation hereunder except to the extent, if any, expressly provided for in any such written consent of Landlord to the foregoing, and none of the foregoing, and no consent to any of the foregoing, shall be deemed to be a consent to or relieve Tenant from obtaining Landlord’s consent to any subsequent assignment, subletting, use, occupancy, transfer or encumbrance. Tenant shall pay all of Landlord’s reasonable third-party out-of-pocket costs, charges and expenses, including, without limitation, reasonable attorneys’ fees and expenses, incurred in connection with any assignment, subletting, use, occupancy, transfer or encumbrance made or requested by Tenant.

(c) Notice of Proposed Assignment or Sublease; Recapture. Tenant shall, by notice in writing, advise Landlord of its intention from, on and after a stated date (which shall not be less than thirty (30) nor more than one hundred eighty (180) days after the date of the giving of Tenant’s notice to Landlord) to assign this Lease or sublet all or any part of the Premises for the balance or any part of the Term, and, in such event, Landlord shall have the right, to be exercised by giving written notice to Tenant within twenty (20) days after its receipt of Tenant’s notice, (1) to terminate this Lease with respect to the space described in Tenant’s notice as of the date stated in Tenant’s notice for the commencement of the proposed assignment or sublease, or (2) to consent or refuse to consent to the proposed assignment or sublease, as described in Section 15(d) below. Tenant’s notice shall include the name and address of the proposed assignee or subtenant, a true and complete copy of the proposed assignment or sublease and sufficient information, as Landlord deems reasonably necessary, to permit Landlord to determine (i) the financial responsibility and character and the nature of the business of the proposed assignee or subtenant, and (ii) whether Landlord has the right under this Lease to withhold consent to the proposed assignment or sublease. If Tenant’s notice covers all of the Premises and if Landlord exercises its right to terminate this Lease as to such space, then the Term of this Lease shall expire and end on the date stated in Tenant’s notice for the commencement of the proposed assignment or sublease as fully and completely as if that date had otherwise been the Expiration Date. If, however, Tenant’s notice covers less than all of the Premises, and if Landlord exercises its right to terminate this Lease with respect to such space described in Tenant’s notice, then as of the date stated in Tenant’s notice for the commencement of the proposed sublease, the Base Rent and Tenant’s Proportionate Share shall be adjusted on the basis of the number of square feet Rentable Area retained by Tenant, and this Lease as so amended, shall continue thereafter in full force and effect.

(d) Grounds for Withholding Consent. If Landlord, upon receiving Tenant’s notice with respect to any such space, does not exercise its right to terminate as aforesaid, Landlord will not unreasonably withhold or delay its consent to Tenant’s assignment of this Lease or subletting the space covered by Tenant’s notice. Landlord shall not be deemed to have unreasonably withheld its consent to a proposed assignment of this Lease or to a proposed sublease of part or all of the Premises if its consent is withheld because: (i) Tenant is then in uncured default hereunder of which Tenant has been notified in writing; (ii) termination of this Lease or

termination of Tenant’s right of possession shall have occurred under Section 19 or any notice of termination of this Lease shall have been given under any other provision of this Lease; (iii) either the portion of the Premises which Tenant proposes to sublease, or the remaining portion of the Premises, or the means of ingress or egress to either the portion of the Premises which Tenant proposes to sublease or the remaining portion of the Premises is of such nature that it will violate any applicable Law, is of such accessibility, size or irregular shape so as not to be suitable for normal renting purposes as space on a multi-tenant floor within the Building; (iv) the proposed use of the Premises by the proposed assignee or subtenant does not conform with the use set forth in Section 6 hereof, or will violate any applicable Law, will impose any obligation upon Landlord or increase Landlord’s obligations under or cost of compliance with any Laws, or will violate any exclusive right Landlord has granted or contemplates granting in the future to any tenant of any part of the Project; (v) in the reasonable judgment of Landlord the proposed assignee or subtenant is of a character or is engaged in a business which would be deleterious to the reputation of the Project, Landlord or any of the constituent members of Landlord; (vi) in the reasonable judgment of Landlord, the proposed assignee or subtenant is not sufficiently financially responsible to perform its obligations under the proposed assignment or sublease; (vii) the proposed assignee or subtenant is a government (or subdivision or agency thereof); or (viii) the proposed assignee or subtenant is an occupant of the Development or is a person or entity Landlord is then dealing with or has dealt with during the prior twelve (12) months with regard to leasing of space in the Development; provided, however, that the foregoing are merely examples of reasons for which Landlord may withhold its consent and shall not be deemed exclusive of any permitted reasons for reasonably withholding consent, whether similar or dissimilar to the foregoing examples, and Landlord may consider all relevant factors in determining whether to give or withhold its consent. Tenant agrees that all advertising by Tenant or on Tenant’s behalf with respect to the assignment of this Lease or subletting of any part of the Premises must be approved in writing by Landlord prior to publication.

(e) Excess Rent Payment. If Tenant (as Tenant or debtor-in-possession) shall assign this Lease or sublet the Premises, or any part thereof, at a rental or for other consideration in excess of the Rent or pro rata portion thereof due and payable by Tenant under this Lease, then Tenant shall pay to Landlord as additional Rent one-half (½) of any such excess rent or other consideration immediately upon receipt under any such assignment or, in the case of a sublease, (i) on the later of the first day of each month during the term of any sublease, or the day of receipt from such subtenant, one-half (½) of the excess of all rent and other consideration paid by the subtenant for such month over the Rent then payable to Landlord pursuant to the provisions of this Lease for said month (or if only a portion of the Premises is being sublet, one-half (½) of the excess of all rent and other consideration due from the subtenant for such month over the portion of the Rent then payable to Landlord pursuant to the provisions of this Lease for said month which is allocable on a Rentable Area basis to the space sublet), and (ii) immediately upon the receipt thereof, one-half (½) of any other consideration realized by Tenant from such subletting. Landlord shall not be responsible for any deficiency if Tenant shall assign this Lease or sublet the Premises or any part thereof at a rental less than that provided for herein. Whenever reference is made to the “excess” of rent or other consideration, such excess shall be reduced by charging (i.e., on an amortized basis over the term of the sublease or assignment) against the rent or other consideration paid by such assignee or subtenant, reasonable brokerage commissions and actual costs of leasehold improvements and other leasing concessions which Tenant has paid in connection with assigning this Lease or subleasing the applicable portion of the Premises.

(f) Lease Assumption; Subtenant Attornment. If Tenant shall assign this Lease, the assignee shall expressly assume all of the obligations of Tenant hereunder in a written instrument provided by Landlord and delivered to Landlord not later than ten (10) days prior to the effective date of the assignment. If Tenant shall sublease any part of the Premises, Tenant shall obtain and furnish to Landlord, not later than ten (10) days prior to the effective date of such sublease and in form reasonably satisfactory to Landlord, the written agreement of such subtenant to the effect that the subtenant will attorn to Landlord, at Landlord’s option and written request (at Lender’s sole election), if this Lease terminates before the expiration of the sublease. Tenant shall, not later than fifteen (15) days after the effective date of any such assignment or sublease, deliver to Landlord a certified copy of the instrument of assignment or sublease.

(g) Corporation, Partnership and Limited Liability Company Transfers. If Tenant is a corporation, any transaction or series of transactions (including without limitation

any dissolution, merger, consolidation or other reorganization of Tenant, or any issuance, sale, gift, transfer or redemption of any capital stock of Tenant, whether voluntary, involuntary or by operation of law, or any combination of any of the foregoing transactions) resulting in the transfer of control of Tenant, other than by reason of death, shall be deemed to be a voluntary assignment of this Lease by Tenant subject to the provisions of this Section 15. If Tenant is a partnership or limited liability company, any transaction or series of transactions (including without limitation any withdrawal or admittance of a partner or member or any change in any partner’s or member’s interest in Tenant, whether voluntary, involuntary or by operation of law, or any combination of any of the foregoing transactions) resulting in the transfer of control of Tenant, other than by reason of death, shall be deemed to be a voluntary assignment of this Lease by Tenant subject to the provisions of this Section 15. The term “control” as used in this Lease means the power to directly or indirectly direct or cause the direction of the management or policies of Tenant.

(h) Assignment or Sublet to Affiliate. Notwithstanding anything to the contrary contained in this Section 15, Tenant may, without the obtaining or seeking the consent of Landlord, assign this Lease or sublet all or any portion of the Premises to an entity which controls, is controlled by or is under common control with Tenant or which results from a merger or consolidation with Tenant or the sale of all or substantially all of Tenant’s assets or capital stock, provided the following conditions are satisfied:

(1) On the effective date of any such assignment or sublease, this Lease shall be in full force and effect, Tenant shall not then be in uncured default under any provision of this Lease as to which Tenant has been given written notice, and no termination of this Lease or termination of Tenant’s right of possession shall have occurred under Section 19 nor shall have any notice of termination of this Lease been given under any other provision of this Lease;

(2) On the effective date of any such assignment, the assignee shall have a net worth not less than the net worth of Tenant as of the date of this Lease or as of the effective date of the proposed assignment, whichever is greater;

(3) A copy of the executed assignment or sublease shall be delivered to Landlord. Such assignment shall be accepted by the assignee and shall provide that the assignee shall assume and be bound by all the covenants, agreements, obligations and liabilities of Tenant under this Lease. Such sublease shall provide that it is subject to the terms, provisions and conditions of this Lease and that the sublessee shall assume and be bound by all of Tenant’s obligations, covenants, agreements and liabilities under this Lease with respect to the subleased portion of the Premises with the exception of Tenant’s obligation to pay Rent to Landlord as provided in this Lease; and

(4) No such assignment or sublease shall release or be construed as releasing any obligation of Tenant under this Lease, and if Landlord so requires, as a condition precedent to the effectiveness of such assignment or sublease, Tenant shall execute an instrument ratifying and confirming such obligations.

(i) Consent to Assignment and/or Sublease to Certain Affiliates of Tenant. Landlord acknowledges that Tenant may elect, from time to time, to sublease, and/or assign this Lease, as to all or portions of the Premises to Terra Nova Trading, L.L.C. and/or Townsend Analytics, Ltd., each of which is an affiliate of the principals of Tenant, or their respective subsidiaries or affiliates (collectively, a “Permitted Transfer”), provided that at least fifteen (15) days prior to the effective date of any such proposed assignment, Tenant shall permit Landlord or its designated agents to examine the current financial statements of Tenant and the proposed assignee for Landlord’s approval (which shall not be withheld provided such financial statements show that the proposed assignee is of at least equivalent financial condition (i.e., tangible net worth and current net income) as Tenant as determined by Landlord in its reasonable business judgment) and that the proposed assignment or sublease otherwise complies with the provisions of this Section 15 which are not inconsistent with the foregoing provisions of this subsection. Except for a Permitted Transfer, all other assignments, sublettings, transfers, etc. with respect to this Lease and the Premises which are or would be covered by the provisions of this Section 15, shall remain subject to the provisions thereof.

16. WAIVER OF CERTAIN CLAIMS, INDEMNITY BY TENANT.

(a) General Waiver. In addition to and without limiting or being limited by any other releases or waivers of claims in this Lease, but rather in confirmation and furtherance thereof, to the extent not prohibited by law, Landlord and Tenant each releases and waives any and all claims for, and rights to recover, damages against and from the other, and the other’s respective agents, members, partners, shareholders, officers, directors and employees (collectively, the “Released Parties”), for loss, damage or destruction to any of its property (including the Premises, the Building and their contents), the elements of which are insured against or which would have been insured against had such party suffering such loss, damage or destruction maintained the property or physical damage insurance policies required under Section 22 hereof. In no event shall this clause be deemed, construed or asserted (i) to affect or limit any claims or rights against any Released Parties other than the right to recover damages for loss, damage or destruction to property, or (ii) to benefit any third party other than the Released Parties.

(b) Indemnity. In addition to and without limiting or being limited by any other indemnity in this Lease, but rather in confirmation and furtherance thereof, to the extent not prohibited by law, Tenant agrees to indemnify, defend by counsel reasonably acceptable to Landlord and hold the Landlord Parties, and the Project, harmless of, from and against any and all losses, damages, liabilities, claims, liens, costs and expenses including court costs and reasonable attorneys’ fees and expenses, in connection with injury to or death of any person or with respect to damage to or theft, loss or loss of the use of any property, occurring in or about the Premises or the Project arising from Tenant’s occupancy of the Premises, or the conduct of its business or from any activity, work, or thing done, permitted or suffered by Tenant in or about the Premises or the Project, or from any breach or default on the part of Tenant in the performance of any covenant or agreement on the part of Tenant to be performed pursuant to the terms of this Lease, or due to any other negligent act or omission or wilful misconduct of Tenant, or any of its employees, agents, licensees, invitees or contractors.

(c) Waiver. To the extent permitted by law, Tenant releases the Landlord Parties from, and waives all claims for, damage or injury to person or property sustained by the Tenant or any occupant of the Building or Premises resulting directly or indirectly from any existing or future condition, defect, matter or thing in and about the Project or the Premises or any part of either or any equipment or appurtenance therein, or resulting from any accident in or about the Project or resulting directly or indirectly from any act or neglect of any tenant or occupant of the Building or of any other person, including Landlord’s agents and servants, except where resulting from the neglect or willful act of Landlord or any of the Landlord Parties. Tenant hereby waives any consequential damages, compensation or claims for inconvenience or loss of business, rents, or profits as a result of any injury or damage occurring at or about the Building.

(d) Landlord’s Negligence. Subject to the provisions of Section 16(a) and Section 16(c) to the extent permitted by law, no agreement of Tenant in this Lease shall be deemed to exempt Landlord from liability or damages for injury to persons or damage to property caused by or resulting from the negligence of Landlord, its agents, servants or employees, in the operation or maintenance of the Premises or the Development.

17. DAMAGE OR DESTRUCTION BY CASUALTY.

(a) Termination of Lease; Repair by Landlord. If the Premises or the Building shall be damaged by fire or other casualty and if such damage does not render all or a substantial portion of the Premises or the Building untenantable, then Landlord shall proceed with reasonable promptness to repair and restore the core and shell of the Building and the Premises so as to render the Premises tenantable, subject to reasonable delays for insurance adjustments and delays caused by matters beyond Landlord’s reasonable control, and also subject to zoning laws and building codes then in effect. If any such damage renders all or a substantial portion of the Premises or the Building untenantable, Landlord shall, with reasonable promptness after the occurrence of such damage, estimate the length of time that will be required to substantially complete the repair and restoration of the Premises and the core and shell of the Building, as the case may be, necessitated by such damage and shall by notice advise Tenant of such estimate. If it is so estimated that the amount of time required to substantially complete such repair and restoration will exceed two hundred seventy (270) days from the date such damage occurred,

then either Landlord or Tenant (but Tenant shall have such right only if the damage was not caused by the willful act of Tenant, its agents, employees, contractors, or invitees, and only if all or a substantial portion of the Premises is rendered untenantable and the estimated time for Landlord required to substantially complete such repair or restoration to render the Premises tenantable will exceed such two hundred seventy (270) day period) shall have the right to terminate this Lease as of the date of notice of such election by giving notice to the other at anytime within twenty (20) days after Landlord gives Tenant the notice containing said estimate (it being understood that Landlord may, if it elects to do so, also give such notice of termination together with the notice containing said estimate). Unless this Lease is terminated as provided in the preceding sentence, Landlord shall proceed with reasonable promptness to repair and restore the core and shell of the Building and the Premises so as to render the Premises tenantable, subject to reasonable delays for insurance adjustments and delays caused by matters beyond Landlord’s reasonable control, and also subject to zoning laws and building codes then in effect. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease (except as hereinafter provided) if such repairs and restoration are not in fact completed within the time period estimated by Landlord, as aforesaid, or within said two hundred seventy (270) days. However, if such repairs and restoration are not completed by a date (“Outside Date”) which is fifteen (15) months after the date of such fire or other casualty (or ninety-five (95) days after the expiration of the time period estimated by Landlord as aforesaid, if longer than two hundred seventy (270) days and neither party terminated this Lease as permitted), which Outside Date shall be extended (as to Tenant’s ability to terminate only) by all periods of delay attributable to the acts or omissions of Tenant or Tenant’s agents, employees or contractors, for any reason whatsoever, then either party may terminate this Lease, effective as of the date of notice of such election, by giving written notice to the other party within thirty (30) day period after said Outside Date as extended as aforesaid, but prior to substantial completion of repair or restoration. Notwithstanding anything to the contrary herein set forth: (i) Landlord shall have no duty pursuant to this Section 17 to repair or restore any portion of Tenant Alterations or by other improvements, additions or alterations made by or on behalf of Tenant in the Premises, including improvements performed by Landlord pursuant to this Lease and/or the Workletter, if any, except to the extent Tenant provides insurance proceeds or other funds to Landlord to pay for such repair or restoration; (ii) Landlord shall not be obligated (but may, at its option, so elect) to repair or restore the Premises or Building if the damage is due to an uninsurable casualty or if insurance proceeds are insufficient to pay for such repair or restoration, or if any Mortgagee applies proceeds of insurance to reduce its loan balance, and the remaining proceeds, if any, available to Landlord are not sufficient to pay for such repair or restoration; or (iii) if any such damage rendering all or substantial portion of the Premises or Building untenantable shall occur during the last year of the Term, either party (but as to Tenant’s right, only if all or a substantial portion of the Premises is rendered untenantable) shall have the option to terminate this Lease by giving written notice to the other within thirty (30) days after the date such damage occurred, and if such option is so exercised, this Lease shall terminate as of the date of such notice.

(b) Repair by Tenant. If this Lease is not terminated pursuant to this Section 17, Tenant shall, in accordance with Section 14, proceed with reasonable promptness to repair and restore all Tenant Alterations and all other alterations, additions and improvements in the Premises, other than any repairs or restoration required to be made by Landlord pursuant to Section 17(a) above, to as near the condition which existed prior to the fire or other casualty as is reasonably possible. Tenant agrees and acknowledges that Landlord shall be entitled to the proceeds of any insurance coverage carried by Tenant relating to improvements and betterments to the Premises, to the extent Landlord is obligated under this Section 17 to repair or restore damage to those items covered by such insurance or if this Lease terminates.

(c) Abatement of Rent. Except to the extent arising from the willful acts of Tenant or its agents, employees, contractors or invitees, in the event any such fire or casualty damage renders the Premises untenantable and if this Lease shall not be terminated pursuant to the foregoing provisions of this Section 17 by reason of such damage, then Rent shall abate during the period beginning with the date of such damage and ending with the date when Landlord substantially completes its repair or restoration required hereunder. Such abatement shall be in an amount bearing the same ratio to the total amount of Rent for such period as the portion of the Rentable Area of the Premises which is untenantable and not used by Tenant from time to time bears to the Rentable Area of the entire Premises. In the event of termination of this Lease

pursuant to this Section 17, Rent shall be apportioned on a per diem basis and be paid to the date of the termination.

(d) Untenantability. As used in this Lease, the term “untenantable” means reasonably incapable of being accessed or occupied for its intended use due to damage to the Premises or Building. Notwithstanding anything contained to the contrary in this Section 17, neither the Premises nor any portion of the Premises shall be deemed untenantable if Landlord is not required to repair or restore same (or if Landlord is required to repair or restore same, then following such time as Landlord has substantially completed the repair and restoration work required to be performed by Landlord under this Section 17), or if Tenant continues to actually occupy the subject portion of the Premises for the conduct of its business.

(e) Core and Shell. The term “core and shell” shall include all base Building improvements at the Building or within the Premises (as the case may be), but specifically excludes any work related to tenant improvements constructed or to be constructed by or for Tenant or other tenants or installed within the Premises or within any other tenant’s premises.

18. EMINENT DOMAIN.

(a) Substantial Taking. If the entire Project or the entire Building, or a substantial part of either of them, or any part of the Project which includes all or a substantial part of the Premises, shall be taken or condemned by any competent authority for any public or quasi-public use or purpose, either party to this Lease shall have the right, at its option, of giving the other, at any time within thirty (30) days after such taking, notice terminating this Lease, except that Tenant may only terminate this Lease by reason of taking or appropriation as above provided, if such taking shall be so substantial as to materially interfere with Tenant’s use and occupancy of the Premises, whereupon the Term of this Lease shall end upon and not before the earlier of the date when the possession of the part so taken shall be required for such use or purpose or the effective date of the taking. If any condemnation proceeding shall be instituted in which it is sought to take or damage any part of the Project, the taking or damaging of which would, in Landlord’s opinion, prevent the economical operation of the Project, or if the grade of any street or alley adjacent to the Land or the Building is changed or any such street or alley is closed by any competent authority, and such taking, damage, change of grade or closing makes it necessary or desirable to remodel the Building to conform to the taking, damage, change of grade or closing, Landlord shall have the right to terminate this Lease upon written notice to Tenant given not less than ninety (90) days prior to the date of termination designated in the notice. In either of the events above referred to, Rent shall be apportioned on a per diem basis and be payable to the date of the termination.

(b) Taking of Part. In the event a part of the Building or the Premises is taken or condemned by any competent authority and this Lease is not terminated as provided in Section 18(a) above, this Lease shall be amended to reduce or increase, as the case may be, the Monthly Base Rent and Tenant’s Proportionate Share to reflect the Rentable Area of the Premises or Building, as the case may be, remaining after any such taking or condemnation. Landlord, upon receipt and to the extent of the award in condemnation (or proceeds of sale) shall make necessary repairs and restorations to the Premises (exclusive of any Tenant Alterations, or any other improvements made by or on behalf of Landlord or Tenant) and to the Building to the extent necessary to constitute the portion of the Building not so taken or condemned as a complete architectural and economically efficient unit.

(c) Compensation. Landlord shall be entitled to receive the entire award (or sale proceeds) from any such taking, condemnation or sale without any payment to Tenant, and Tenant hereby assigns to Landlord all of Tenant’s interest, if any, in such award; provided, however, Tenant shall have the right separately to pursue against the condemning authority a separate award in respect of the loss, if any, to Tenant Alterations paid for by Tenant without any credit or allowance from Landlord, so long as there is no diminution of Landlord’s award as a result, and subject to the rights of any ground lessor or mortgagee of Landlord with respect thereto.

19. DEFAULT; LANDLORD’S RIGHTS AND REMEDIES.

(a) Default. The occurrence of any one or more of the following matters constitutes a “Default” by Tenant under this Lease:

(i) Failure by Tenant to pay any Rent when due, if such failure continues for five (5) days after written notice to Tenant of such failure;

(ii) Failure by Tenant to pay any other money required to be paid by Tenant under this Lease when due, if such failure continues for five (5) days after written notice to Tenant of such failure;

(iii) Failure by Tenant to observe or perform any of the covenants in respect of assignment and subletting set forth in Section 15;

(iv) Failure by Tenant to cure forthwith, immediately after receipt of notice from Landlord, any hazardous condition which Tenant has created or permitted in violation of law or of this Lease;

(v) Failure by Tenant to complete, execute and deliver any instrument or document required to be completed, executed and delivered by Tenant pursuant to Section 20 or Section 24 of this Lease, within ten (10) days after the initial written demand therefor to Tenant if such failure continues for five (5) days after written notice to Tenant of such failure;

(vi) Failure by Tenant to observe or perform any other covenant, agreement, condition or provision of this Lease, if such failure shall continue for twenty (20) days after written notice thereof from Landlord to Tenant; provided that such 20-day period shall be extended for the time reasonably required to complete such cure (not to exceed, in any event, an additional 60-day period), if such failure cannot reasonably be cured within said 20-day period and Tenant commences to cure such failure within said 20-day period and thereafter diligently and continuously proceeds to cure such failure;

(vii) The levy upon execution or the attachment by legal process of the leasehold interest of Tenant, or the filing or creation of a lien in respect of such leasehold interest, which lien shall not be released or discharged within thirty (30) days from the date of such filing;

(viii) Tenant becomes insolvent or bankrupt or admits in writing its inability to pay its debts as they mature, or makes an assignment for the benefit of creditors, or applies for or consents to the appointment of a trustee or receiver for Tenant or for the major part of its property;

(ix) A trustee or receiver is appointed for Tenant or for a major part of its property, without Tenant’s application therefor or consent thereto, and is not discharged within sixty (60) days after such appointment;

(x) Any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding, or other proceeding for relief under any bankruptcy law or similar law for the relief of debtors, is instituted (A) by Tenant, or (B) against Tenant and is allowed against it or is consented to by it or is not dismissed within sixty (60) days after such institution; or

(xi) Upon the third occurrence within any twelve-month period that Tenant fails to pay Rent when due or has breached a particular covenant of this Lease (whether or not such failure or breach is thereafter cured within any stated cure or grace period or statutory period).

(b) Landlord’s Rights and Remedies. If a Default occurs, Landlord shall have the rights and remedies hereinafter set forth, which shall be distinct, separate and cumulative and shall not operate to exclude or deprive Landlord of any other right or remedy allowed it at law or in equity:

(i) Landlord may terminate this Lease, in which event the Term of this Lease shall end, and all right, title and interest of Tenant hereunder shall expire;

(ii) Landlord may terminate the right of Tenant to possession of the Premises without terminating this Lease, whereupon the right of Tenant to possession of the Premises or any part thereof shall cease; and

(iii) Landlord may enforce the provisions of this Lease and may enforce and protect the rights of Landlord hereunder by a suit or suits in equity or at law for the specific performance of any covenant or agreement contained herein, and for the enforcement of any other appropriate legal or equitable remedy, including without limitation distraint for rent, injunctive relief, recovery of all money due or to become due from Tenant under any of the provisions of this Lease and recovery of damages incurred by Landlord by reason of the Default.

(iv) Landlord may cure or correct such Default or take steps to perform any covenant, agreement, condition or provisions of this Lease, and all costs and expenses incurred by Landlord in so doing (including reasonable attorneys’ fees) shall be paid by Tenant to Landlord as additional rent upon demand plus interest at the Default Rate (defined in Section 28(i)) from the date of expenditure. Landlord’s proceeding under the rights reserved to Landlord under this Section 19(b)(iv) shall not in any way prejudice or waive any rights as Landlord might otherwise have against Tenant by reason of that or any other Default.

Notwithstanding anything to the contrary herein contained, Landlord shall not be required to serve Tenant with any notices or demands as a prerequisite to its exercise of any of its rights or remedies under this Lease, other than those notices and demands specifically required under this Lease. Tenant expressly waives the service of any statutory demand or notice which is a prerequisite to Landlord’s commencement of eviction proceedings against Tenant, including the demands and notices specified in 735 ILCS §§5/9-209 and 5/9-210.

(c) Surrender. If Landlord exercises any of the remedies provided for in subparagraphs (i) and (ii) of Section 19(b), Tenant shall surrender possession of and vacate the Premises and immediately deliver possession thereof to Landlord, and Landlord may re-enter and take complete and peaceful possession of the Premises, with or without process of law, full and complete license so to do being hereby granted to Landlord, and Landlord may remove all occupants and property therefrom, using such force as may be necessary, without being deemed in any manner guilty of trespass, eviction or forcible entry and detainer, and without relinquishing Landlord’s right to Rent or any other right given to Landlord hereunder or by law or in equity.

(d) Termination of Right of Possession. If Landlord terminates the right of Tenant to possession of the Premises without terminating this Lease, as provided for by subparagraph (ii) of Section 19(b), then Landlord shall be entitled to recover from Tenant all the fixed dollar amounts of Rent accrued and unpaid for the period up to and including such termination date, as well as all other additional sums payable by Tenant, or for which Tenant is liable or in respect of which Tenant has agreed to indemnify Landlord under any of the provisions of this Lease, which may be then owing and unpaid, and all costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses incurred by Landlord in the enforcement of its rights and remedies hereunder, and in addition, Landlord shall be entitled to recover from Tenant from time to time, and Tenant shall remain liable for, all Rent and all other additional sums thereafter accruing as they become due under this Lease during the period from the date of such notice of termination of possession to the stated end of the Term. In any such case, Landlord shall use reasonable efforts as required by applicable law to relet the Premises for the account of Tenant for such rent, for such time (which may be for a term extending beyond the Term of this Lease), in such portions and upon such terms as Landlord in Landlord’s sole discretion shall determine, and Landlord shall not be required to accept any tenant offered by Tenant or to observe any instructions given by Tenant relative to such reletting. Landlord may give priority over leasing the Premises to any other space Landlord desires to lease in the Building and shall not be required in any case to offer rent, length of terms or other terms for the Premises which are or would be less favorable to Landlord than being offered for comparable space of Landlord in the Building. Also, in any such case, Landlord may make

repairs, alterations and additions in or to the Premises and redecorate the same to the extent deemed by Landlord necessary or desirable, and in connection therewith Landlord may change the locks to the Premises, and Tenant shall upon written demand pay the cost thereof together with Landlord’s expenses of reletting. Landlord may collect the rents from any such reletting and shall apply the same first to the payment of the expenses of reentry, redecoration, repair, alterations and reletting and second to the payment of Rent herein provided to be paid by Tenant, and any excess or residue shall operate only as an offsetting credit against the amount of Rent, if any, due and owing or as the same thereafter becomes due and payable hereunder, but the use of such offsetting credit to reduce the amount of Rent due Landlord, if any, shall not be deemed to give Tenant any right, title or interest in or to such excess or residue, and any such excess or residue shall belong to Landlord solely; provided that in no event shall Tenant be entitled to such a credit against Rent in excess of the aggregate sum (including Base Rent and Additional Rent) which would have been paid by Tenant for the period for which the credit to Tenant is being determined had no Default occurred. No such re-entry, repossession, repairs, alterations, additions or reletting shall be construed as an eviction or ouster of Tenant or as an election on Landlord’s part to terminate this Lease, unless a written notice of such intention is given to Tenant, or shall operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, and Landlord may, at any time and from time to time, sue and recover judgment for any deficiencies from time to time remaining after the application from time to time of the proceeds of any such reletting.

(e) Termination of Lease. In the event of the termination of this Lease by Landlord as provided for by subparagraph (i) of Section 19(b), Landlord shall be entitled to recover from Tenant all the fixed dollar amounts of Rent accrued and unpaid for the period up to and including such termination date, as well as all other additional sums payable by Tenant, or for which Tenant is liable or in respect of which Tenant has agreed to indemnify Landlord under any of the provisions of this Lease, which may be then owing and unpaid, and all costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses incurred by Landlord in the enforcement of its rights and remedies hereunder, and in addition, Landlord shall be entitled to recover an amount equal to the present value (calculated using a discount rate equal to six percent (6%) per annum) of the aggregate Base Rent payable for the period from the termination date stated in Landlord’s notice terminating this Lease until the date which would have been the Expiration Date but for such termination, less the present value (calculated using a discount rate equal to six percent (6%) per annum) of the fair rental value of the Premises for the same period (which fair rental value shall be calculated so as to include a reasonable vacancy period for reletting the Premises and deductions for reasonable expenses and inducements incurred by Landlord to achieve such reletting, including without limitation attorneys’ fees and expenses, brokerage fees, advertising costs, rent abatements, tenant improvement allowances and the like).

(f) Tenant’s Property. All property of Tenant removed from the Premises by Landlord or which becomes Landlord’s property pursuant to any provisions of this Lease or by law may be handled, removed or stored by Landlord at the cost and expense of Tenant, and Landlord shall in no event be responsible for the value, preservation or safekeeping thereof. Tenant shall pay Landlord for all expenses incurred by Landlord in such removal and for storage charges for such property so long as the same shall be in Landlord’s possession or under Landlord’s control. All property not removed from the Premises or retaken from storage by Tenant on or before the end of the Term, however terminated, or the termination of Tenant’s right of possession, shall, at Landlord’s option, be conclusively deemed to have been conveyed by Tenant to Landlord as by bill of sale, without further payment or credit by Landlord to Tenant.

(g) Bankruptcy Acceptance or Rejection. If Landlord shall not be permitted to terminate this Lease or Tenant’s right of possession of the Premises under the Bankruptcy Code, Tenant on behalf of itself as a tenant-in-possession or on behalf of any bankruptcy trustee for Tenant (alternatively referred to as “Tenant” in this Section 19(e)) agrees, within sixty (60) days after request by Landlord to the bankruptcy court having jurisdiction over Tenant’s bankrupt estate (the “Bankruptcy Court”), to assume or reject this Lease, and Tenant agrees not to seek or request any extension or continuation of such time in any bankruptcy proceeding to assume or reject this Lease.

Tenant’s right to assume this Lease as aforesaid shall be expressly conditioned upon Tenant fully satisfying the requirements under Section 365(b)(1) of the Bankruptcy Code, as such Section may be amended from time to time. In no event after such assumption of this Lease shall any then existing Default remain uncured for a period in excess of the earlier of ten (10) days or the time period for curing such default as set forth herein. Failure to cure such default within such time shall constitute a Default hereunder.

Landlord and Tenant agree that adequate assurance of performance of this Lease, as set forth in Section 365(b)(1) of the Bankruptcy Code, as such Section may be amended from time to time, with respect to any monetary Default under this Lease, shall be in the form of cash or immediately available funds in an amount equal to at least the amount of such monetary Default so as to assure the Landlord that it will realize the amount of such Default.

If Tenant assumes this Lease and proposes to assign this Lease pursuant to the provisions of the Bankruptcy Code to any person or entity who shall have made a bona fide offer to accept an assignment of this Lease, then notice of such proposed assignment, setting forth (i) the name and address of such person or entity, (ii) all of the terms and conditions of such offer, and (iii) the adequate assurance to be provided Landlord to assure such person’s or entity’s future performance under this Lease, shall be given to Landlord by Tenant within twenty (20) days after receipt of such offer by Tenant and in no event later than ten (10) days prior to the date that Tenant shall make application to the Bankruptcy Court for authority and approval to enter into such assumption and assignment. In addition, Landlord shall thereupon have the right of first refusal, to be exercised by notice to Tenant given within ten (10) days prior to the effective date of such proposed assignment, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer made by such person or entity, less any brokerage commissions which may be payable out of any consideration to be paid by such person or entity for the assignment of this Lease.

Any person or entity to which this Lease is assigned pursuant to the provisions of the Bankruptcy Code shall be deemed, without further act or deed, to have assumed all of the obligations arising under this Lease on and after the date of such assignment; provided, however, that any options to renew or extend the Term of this Lease, and any right of offer or refusal or other options or rights to lease additional space in the Building shall be terminated effective as of the date on which such petition was filed with the Bankruptcy Court. Any such assignee shall upon demand execute and deliver to Landlord an instrument confirming such assumption of this Lease on such terms. Nothing contained in this Section shall, in any way, constitute a waiver of any provisions of this Lease relating to assignment or subletting.

All monies or other considerations payable by Tenant or otherwise to be delivered to or on behalf of Landlord under this Lease, whether or not expressly denominated as Rent hereunder, shall constitute rent for the purposes of Section 502(b)(6) of the Bankruptcy Code, as such Section may be amended from time to time, and be the sole property of Landlord.

From and after the date of the filing of any petition with the Bankruptcy Court, to the extent permitted by applicable law, Landlord shall have no obligation to provide any services or utilities to the Premises as herein required, unless and until Tenant shall have paid and be current in all payments or other charges therefor. Such payments and charges shall constitute administrative charges or expenses under Section 507(a)(1) of the Bankruptcy Code, as such Section may be amended from time to time.

(h) Waiver of Notices Not Provided for in this Lease. Tenant expressly waives the service of any notice of intention to terminate this Lease or to reenter the Premises and waives the service of any demand for payment of rent or for possession and waives the service of any and every other notice or demand prescribed by any ordinance, statute or other law (except as expressly otherwise provided in this Lease) and agrees that the breach of any covenants or agreements provided in this Lease shall, in and of itself, without the service of any notice or demand whatever (except as expressly otherwise provided in this Lease), constitute a forcible detainer by Tenant of the Premises.

(i) No Counterclaim. If Landlord commences any summary proceeding for possession of the Premises (or any portion thereof) due to non-payment of Rent, Tenant will not

interpose any non-compulsory counterclaim of whatever nature or description in any such proceeding.

20. RIGHTS OF MORTGAGEES AND GROUND LESSORS.

(a) Subordination of Lease. Landlord may have heretofore or may hereafter encumber with a mortgage or trust deed the Building, the Land, the Project, any part thereof or any interest therein, may sell and lease back the Land, or any part of the Project, and may encumber the leasehold estate under such a sale and leaseback arrangement with a mortgage or trust deed. (Any such mortgage or trust deed is herein called a “Mortgage” and the holder of any such mortgage or the beneficiary under any such trust deed is herein called a “Mortgagee.” Any such lease of the Land or other part of the Project is herein called a “Ground Lease” and the lessor under any such lease is herein called a “Ground Lessor.”) This lease and the rights of Tenant hereunder shall be and are hereby expressly made subject to and subordinate at all times to any Mortgage and to any Ground Lease now or hereafter existing, and to all amendments, modifications, renewals, extensions, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security thereof. So long as Tenant is not in Default hereunder, Landlord and Tenant agree that Tenant’s covenant to subordinate this Lease to any future Mortgage or Ground Lease shall be conditioned upon the Mortgagee’s or Ground Lessor’s agreement to recognize Tenant’s rights and obligations under this Lease upon an attornment to such Mortgagee or Ground Lessor by Tenant which agreement shall be upon such Mortgagee’s or Ground Lessor’s then current and commercially reasonable form thereof. Landlord shall obtain a Subordination, Nondisturbance and Attornment Agreement from the current First Mortgagee in the form attached hereto as Exhibit H (the “SNDA”). Tenant agrees to execute and deliver the SNDA to such current First Mortgagee and to pay any and all reasonable fees and charges imposed by such current First Mortgagee to prepare, negotiate and execute same. Tenant agrees to execute and deliver to Landlord such further instruments consenting to or confirming the subordination of this Lease to any Mortgage and to any Ground Lease and containing such other provisions which may be requested in writing by Landlord within ten (10) days after Tenant’s receipt of such written request. In the event of any conflict between the terms and provisions of the SNDA and the terms and provisions of this Article 20, as between Tenant and the current First Mortgagee, its successors and assigns, the terms and provisions of the SNDA shall control.

(b) Notice of and Opportunity to Cure Defaults. Tenant agrees that if Landlord defaults in the performance or observance of any covenant or condition of this Lease required to be performed or observed by Landlord hereunder, Tenant will give written notice specifying such default by certified or registered mail, postage prepaid, to any Mortgagee or Ground Lessor of which Tenant has been notified in writing, and before Tenant exercises any right to terminate this Lease which Tenant may have on account of any such default of Landlord, such Mortgagee or Ground Lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default (or if such default cannot be cured within that time, then such additional time as may be necessary, if, within such thirty (30) days, any Mortgagee or Ground Lessor has commenced and is diligently pursuing the remedies necessary to cure such default, including but not limited to commencement of foreclosure proceedings or other proceedings to acquire possession of the mortgaged or leased estate, if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or Ground Lessor is prevented from commencing or pursuing such foreclosure proceedings or other proceedings to acquire possession of the mortgaged or leased estate by reason of Landlord’s bankruptcy.

(c) Rights of Successors. Subject to the applicable provisions of the SNDA with respect to the current First Mortgage, if any Mortgage is foreclosed, or Landlord’s interest under this Lease is conveyed or transferred in lieu of foreclosure, or if any Ground Lease is terminated:

(i) No person or entity which as the result of any of the foregoing has succeeded to the interest of Landlord in this Lease (any such person or entity being hereafter called a “Successor”) shall be liable for any default by Landlord or any other matter which occurred prior to the date such Successor succeeded to Landlord’s interest in this Lease, nor shall such Successor be bound by or subject to any offsets or defenses which Tenant may have against Landlord or any other predecessor in interest to such Successor.

(ii) Upon request of any Successor, Tenant will attorn to such Successor, as Landlord under this Lease, subject to the provisions of this Section 20(c) and Section 20(e), and will execute and deliver such instruments as may be necessary or appropriate to evidence such attornment within ten (10) days after receipt of a written request to do so.

(iii) No Successor shall be bound to recognize any prepayment by more than thirty (30) days of Base Rent, Additional Rent or Additional Rent Estimate.

(iv) No Successor shall be bound to recognize any amendment or modification of this Lease made without the written consent of the Mortgagee or Ground Lessor (as the case may be).

(d) Subordination of Mortgage. Notwithstanding anything to the contrary contained herein, any Mortgagee may subordinate, in whole or in part, its Mortgage to this Lease by sending Tenant notice in writing subordinating all or any part of such Mortgage to this Lease, and Tenant agrees to execute and deliver to such Mortgagee such further instruments consenting to or confirming the subordination of all or any portion of its Mortgage to this Lease and containing such other provisions which may be requested in writing by such Mortgagee within ten (10) days after Tenant’s receipt of such written request.

(e) Liability of Mortgagee and Ground Lessor. Whether or not any Mortgage is foreclosed or any Ground Lease is terminated, or any Mortgagee or Ground Lessor succeeds to any interest of Landlord under this Lease, no Mortgagee or Ground Lessor shall have any liability to Tenant for any security deposit paid to Landlord by Tenant hereunder, unless such security deposit has actually been received by such Mortgagee or Ground Lessor.

(f) Requests by Mortgagee or Ground Lessor. Should any prospective Mortgagee or Ground Lessor require a modification or modifications of this Lease, which modification or modifications will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, in the reasonable judgment of Tenant, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are required therefor and deliver the same to Landlord within ten (10) days following written request therefor. Should any prospective Mortgagee or Ground Lessor require execution of a short form of this Lease for recording (containing, among other customary provisions, the names of the parties, a description of the Premises and the Term of this Lease), Tenant agrees to execute such short form of lease and deliver the same to Landlord within ten (10) days following the request therefor.

21. DEFAULT UNDER OTHER LEASES.

If the term of any lease, other than this Lease, heretofore or hereafter made by Tenant for any space in the Building shall be terminated or terminable after the making of this Lease because of any default by Tenant or any such other party under such other lease, such fact shall empower Landlord, at Landlord’s sole option, to terminate this Lease by written notice to Tenant or to exercise any of the rights or remedies set forth in Section 19.

22. INSURANCE AND SUBROGATION.

(a) Tenant’s Insurance. Tenant shall carry insurance during the entire Term hereof insuring Tenant, and insuring Landlord, Landlord’s constituent members and agents, all Mortgagees and Ground Lessors and their respective agents, partners and employees, with terms, coverages and in companies satisfactory to Landlord, and with such changes in insured parties and increase in limits as Landlord may from time to time request, but initially Tenant shall maintain the following coverages in the following amounts:

(i) Commercial general liability insurance with the broad form commercial liability endorsement, including contractual liability insurance covering Tenant’s indemnity obligations hereunder, insuring against claims for death, bodily injury, personal injury and property damage occurring upon, in or about the Premises in an amount not less than $5,000,000.00 per occurrence and having a general aggregate

amount on a per location basis of not less than $5,000,000.00. Landlord shall be named as an additional insured on such policy.

(ii) “All risk” physical damage insurance including fire, sprinkler leakage, vandalism and extended coverage for the full replacement cost of all Landlord’s Work, Landlord’s Additional Work, Tenant’s Alterations, and all other additions, improvements and alterations to the Premises (providing that Landlord is an additional named insured as its interest may appear) and of all office furniture, trade fixtures, office equipment, merchandise and all other items of Tenant’s property on the Premises.

(iii) Workers’ Compensation and Employers’ Liability insurance in an amount of not less than $1,000,000.00, both in accordance with the laws of the State of Illinois.

(iv) Such other insurance or coverage as Landlord reasonably requests.

Tenant shall, prior to the commencement of the Term and from time to time during the Term (and, in any event, not less than ten days prior to the expiration of any such policy), furnish to Landlord certificates of insurance (with proof of payment) and, if requested by Landlord, copies of all policies, evidencing the foregoing insurance coverage. Tenant’s policies shall state that such insurance coverage may not be amended, cancelled or not renewed without at least thirty (30) days’ prior written notice to Landlord and Tenant, and shall further provide that the policy shall not be invalidated should the insured party have waived in writing prior to a loss, any and all rights of the insured party against any other party for losses covered by such policy.

(b) Waiver of Subrogation. Landlord and Tenant each agree to have all property or physical damage insurance which it may carry endorsed with a clause providing that any release from liability of or waiver of claim for recovery from the other party or any of the parties named in Section 22(a) above or any of the Released Parties described in Section 16(a) entered into in writing by the insured thereunder prior to any loss or damage shall not affect the validity of said policy or the right of the insured to recover thereunder. Tenant’s policy shall provide further that the insurer waives all rights of subrogation which such insurer might have against any of the parties named in Section 22(a) above or any of the Released Parties described in Section 16(a). Tenant further agrees to first seek recovery under any applicable insurance policy before proceeding against Landlord. Notwithstanding the foregoing or anything contained in this Lease to the contrary, any release or waiver of claims shall not be operative, nor shall the foregoing endorsements be required, in any case where the effect of such release or waiver is to invalidate insurance coverage or invalidate the right of the insured to recover thereunder or increase the cost thereof (provided that in the case of increased cost the other party shall have the right, within ten (10) days following written notice, to pay such increased cost, thereby keeping such release or waiver in full force and effect).

(c) Landlord’s Insurance. Landlord shall carry during the Term hereof replacement cost property insurance on the Building core and shell (including all base Building improvements at the Building but excluding Landlord’s Work, Tenant’s Alterations and all other alterations, additions or improvements to the Premises) against fire and other extended coverage perils in an amount sufficient to prevent Landlord from being deemed a co-insurer of the risks insured under the policy.

23. NONWAIVER.

No waiver of any condition expressed in this Lease shall be implied by any neglect of Landlord to enforce any remedy on account of the violation of such condition, whether or not such violation be continued or repeated subsequently, and no express waiver shall affect any condition other than the one specified in such waiver and that one only for the time and in the manner specifically stated. Without limiting Landlord’s rights under the provisions of Section 11, it is agreed that no receipt of money by Landlord from Tenant after the termination in any way of the Term or of Tenant’s right of possession hereunder or after the giving any notice shall reinstate, continue or extend the Term or affect any notice given to Tenant prior to the receipt of such money. It is also agreed that after the service of notice or the commencement of a suit or after final judgment for possession of the Premises, Landlord may receive and collect any money due, and Landlord’s receipt and collection of said money shall not waive or affect any said notice, suit or judgment.

24. ESTOPPEL CERTIFICATE.

Tenant agrees that from time to time upon not less than ten (10) days’ prior request by Landlord, or any existing or prospective Mortgagee or Ground Lessor, Tenant will, and Tenant will cause any subtenant, licensee, concessionaire or other occupant of the Premises claiming by, through or under Tenant, to complete, execute and deliver to Landlord or Landlord’s designee or to any existing or prospective Mortgagee or Ground Lessor, a written estoppel certificate certifying (a) that this Lease is unmodified and is in full force and effect (or if there have been modifications, that this Lease, as modified, is in full force and effect and setting forth the modifications); (b) the amounts of the monthly installments of Base Rent and Additional Rent Estimate then required to be paid under this Lease; (c) the date to which Rent has been paid; (d) that to the best of Tenant’s knowledge, Landlord is not in default under any of the provisions of this Lease, or if in default, the nature thereof in detail and what is required to cure same; and (e) such other information concerning the status of this Lease or the parties’ performance hereunder reasonably requested by Landlord or the party to whom such estoppel certificate is to be addressed. Tenant’s failure to complete, execute and deliver such estoppel certificate within the aforesaid 10-day period, if such failure continues for five (5) days after written notice to Tenant of such failure, shall be deemed to be a Default under Section 19 of this Lease.

25. TENANT CORPORATION, LIMITED LIABILITY COMPANY OR PARTNERSHIP.

In case Tenant is a corporation or a limited liability company, (a) Tenant represents and warrants that this Lease has been duly authorized, executed and delivered by and on behalf of Tenant and constitutes the valid and binding agreement of Tenant in accordance with the terms hereof, and (b) if Landlord so requests, Tenant shall deliver to Landlord, concurrently with the delivery of this Lease executed by Tenant, resolutions of the board of directors or board of managers (and shareholders and/or members, if required) of Tenant authorizing Tenant’s execution and delivery of this Lease and the performance of Tenant’s obligations hereunder, certified as true and correct by any authorized representative of Tenant. In case Tenant is a partnership, (a) Tenant represents and warrants that all of the persons who are general or managing partners in said partnership have executed this Lease on behalf of Tenant, or that this Lease has been executed and delivered pursuant to and in conformity with a valid and effective authorization therefor by all of the general or managing partners of such partnership, and is and constitutes the valid and binding agreement of the partnership and each and every partner therein in accordance with its terms, to the extent permitted by law, and (b) if Landlord so requests, Tenant shall deliver to Landlord, concurrently with the delivery of this Lease executed by Tenant, authorization of the general partners (and limited partners, if required) of Tenant authorizing Tenant’s execution and delivery of this Lease and the performance of Tenant’s obligations hereunder, certified as true and correct by a general partner of Tenant. Also, it is agreed that each and every present and future individual general partner, if Tenant is a partnership, in Tenant shall be and remain at all times jointly and severally liable hereunder, to the extent permitted by law, and that the death, resignation or withdrawal of any such partner shall not release the liability of such partner under the terms of this Lease unless and until Landlord shall have consented in writing to such release. If Tenant is a partnership, limited liability company or corporation whose stock is not publicly traded, Tenant represents and warrants to Landlord that it has disclosed in writing to Landlord the persons or entities who individually or collectively own a controlling interest in Tenant as of the date of the execution of this Lease provided that Landlord shall not disclose such information to any third party other than its lenders, partners, members, agents, consultants, advisors, attorneys and accountants or as may be otherwise required by a government or governmental agency or pursuant to court order.

26. REAL ESTATE BROKERS.

Landlord and Tenant each represents and warrants to the other party that it did not deal with any broker in connection with this lease other than the Brokers identified in Section 1(b). Landlord hereby agrees to pay the brokerage commissions payable to said Brokers in accordance with a written agreement between Landlord and such Broker. Tenant shall indemnify, defend and hold the Landlord Parties and the Project, harmless of, from and against any and all losses, damages, liabilities, claims, liens, costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses, arising from any claims or demands of any other broker or brokers or finders for any commission alleged to be due such other broker or brokers or

finders claiming to have dealt with Tenant in connection with this lease or with whom Tenant hereafter deals or whom Tenant employs. Landlord shall indemnify, defend and hold Tenant harmless of, from and against any and all losses, damages, liabilities, claims, liens, costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses, arising from any claims or demands of any broker or brokers or finders for any commission alleged to be due such broker or brokers or finders claiming to have dealt with Landlord in connection with this lease or with whom Landlord hereafter deals or whom Landlord employs.

27. NOTICES.

All notices, waivers, demands, requests or other communications required or permitted hereunder shall, unless otherwise expressly provided, be in writing and be deemed to have been properly given, served and received (a) if delivered personally or by same-day courier messenger, when delivered, (b) if sent by nationally recognized overnight courier, on the first (1st) business day after deposit with said courier, and (c) if mailed, on the third (3rd) business day after deposit in the United States Mail, certified or registered, postage prepaid, return receipt requested to the appropriate Address for Notices set forth in Section 1(aa) of the Basic Provisions.

28. MISCELLANEOUS.

(a) Successors and Assigns. Each provision of this Lease shall extend to and shall bind and inure to the benefit not only of Landlord and Tenant, but also their respective heirs, legal representatives, successors and assigns, but this provision shall not operate to permit any assignment, subletting, mortgage, lien, charge, or other transfer or encumbrance contrary to the provisions of this Lease.

(b) Amendment. No modification, waiver or amendment of this Lease or of any of its conditions or provisions shall be binding upon Landlord unless the same shall be in writing and signed by Landlord.

(c) Offer. Submission of this instrument for examination shall not constitute a reservation of or option for the Premises or in any manner bind Landlord, and no lease or obligation on Landlord shall arise until this instrument is signed and delivered by Landlord and Tenant; provided, however, the execution and delivery by Tenant of this Lease to Landlord, or its agents, shall constitute an irrevocable offer by Tenant to lease the Premises on the terms and conditions herein contained, which offer may not be revoked for thirty (30) days after such delivery.

(d) Tenant. The word “Tenant” whenever used herein shall be construed to mean Tenants or any one or more of them in all cases where there is more than one Tenant; and the necessary grammatical changes required to make the provisions hereof apply either to corporations or other organizations, partnerships or other entities, or individuals, shall in all cases be assumed as though in each case fully expressed. In all cases where there is more than one Tenant, (a) the liability of each shall be joint and several and (b) any one person or entity comprising Tenant may give any notice or approval required or permitted to be given by Tenant under this Lease and such notice or approval shall be deemed binding upon all persons or entities comprising Tenant and may be relied upon by Landlord as if such notice or approval had been given by all persons or entities comprising Tenant.

(e) Expenses of Enforcement. The non-prevailing party shall pay upon demand all of the reasonable costs, charges and expenses (including the court costs and fees and out-of-pocket expenses of counsel, agents and others retained by the prevailing party) incurred by the prevailing party in enforcing the terms of this Lease, and a party shall also pay such costs and expenses incurred by the other party in any litigation, negotiation or transaction in which said party causes the other party without the other party’s fault to become involved or concerned. Any amount due from Tenant to Landlord pursuant to this Section shall be deemed to be additional Rent due under this Lease.

(f) Exhibits and Riders. Exhibits and riders, if any, referred to in or affixed to this Lease are made an integral part hereof.

(g) Approval of Plans and Specifications. Neither review nor approval by or on behalf of Landlord of any plans and specifications for any Tenant Alterations or any other work shall constitute a representation or warranty by Landlord, any of Landlord’s constituent members, or any of their respective agents, partners or employees, that such plans and specifications either (i) are complete or suitable for their intended purpose, or (ii) except as otherwise provided in the Workletter with respect to Landlord’s Work and Landlord’s Additional Work, comply with applicable Laws, it being expressly agreed by Tenant that neither Landlord, nor any of Landlord’s constituent members, nor any of their respective agents, partners or employees, assume any responsibility or liability whatsoever to Tenant or to any other person or entity for such completeness, suitability or compliance.

(h) Time of Essence. Time is of the essence of this Lease and of each and all provisions hereof.

(i) Due Date; Interest; Late Charge. Except as otherwise specifically provided in this Lease, all amounts owed by Tenant to Landlord pursuant to any provision of this Lease shall be paid by Tenant within five (5) days after Landlord’s written demand, and all such amounts (including, without limitation, Base Rent and Additional Rent) shall bear interest from the date Default occurs with respect thereto until paid at the annual rate equal to the Default Rate (hereinafter defined), unless a lesser rate shall then be the maximum rate permissible by law with respect thereto, in which event such lesser rate shall be charged. If the Tenant fails to pay any amount of Rent when due, and such failure shall continue for a period of five (5) days after written notice to Tenant of such failure, Tenant shall pay to the Landlord, in addition to the aforesaid interest, a late charge of five percent (5%) of such overdue amount; provided, however, that if Tenant is late in the payment of Rent more than two (2) times in any twelve (12) month period, thereafter such late charge shall be payable immediately upon the occurrence of any subsequent late payment within such 12-month period without any notice or grace period, and provided further that nothing contained herein shall be construed as permitting the Landlord to charge or receive interest in excess of the maximum rate then allowed by law. The term “Default Rate” means five (5) percentage points in excess of the rate of interest announced from time to time by BankOne, Chicago, Illinois (or its successor), as its “prime rate” or “corporate base rate,” changing as and when such rate changes, or if such rate is no longer in existence, then such other “prime rate” as may be designated by Landlord. The provisions of this subparagraph shall in no way relieve Tenant of the obligation to pay Rent or any other sums due hereunder on or before the date on which payment is due, nor shall the collection by Landlord of any amount under this subparagraph impair the ability of Landlord to collect any amount under Section 19 of this Lease.

(j) Interpretation. The invalidity of any provision of this Lease shall not, to the extent commercially reasonable, impair or affect in any manner the validity, enforceability or effect of the rest of this Lease.

(k) Force Majeure. Without limiting or being limited by the provisions of Section 8 or Section 13, or any of the other provisions of this Lease (except for Tenant’s obligation to timely pay Rent), if Landlord or Tenant fails to perform timely any of the terms, covenants or conditions of this Lease on such party’s part to be performed, and such failure is due in whole or in part to any strike, lockout, labor trouble, civil disorder, riot, insurrection, act of terrorism, war, accident, fire or other casualty, adverse weather condition, act of God, governmental inaction, restrictive governmental law or regulation, inability to procure materials, electricity, gas, other fuel or water or other utilities at the Building after reasonable effort to do so, act or event caused directly or indirectly by or by default of the other party or any of the other party’s employees, agents, licensees, invitees or contractors, concealed subsurface condition not reasonably anticipated from test results obtained prior to commencement of work or any cause beyond the reasonable control of the non-performing party, then the non-performing party shall not be deemed in default under this Lease as a result of such failure.

(l) Application of Payments. Landlord shall have the right to apply payments received from Tenant pursuant to this Lease (regardless of Tenant’s designation of such payments) to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect.

(m) Cumulative Remedies; Illinois Law. The rights and remedies of Landlord under this Lease are cumulative and none shall exclude any other rights or remedies allowed by law or equity. This Lease is for the lease of space in a building located in the State of Illinois and is declared to be an Illinois contract, and all of its terms shall be construed according to the laws of the State of Illinois.

(n) Counterparts. This lease may be simultaneously executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument, except that in the event of variation or discrepancy between counterparts, the counterpart held by Landlord shall control.

(o) Relationship. Landlord and Tenant disclaim any intention to create a joint venture, partnership or agency relationship.

(p) Action on Behalf of Landlord. Any service which may be provided by Landlord under this Lease may be provided by Landlord, any of its constituent members, or any agent or contractor of any of them, and the cost to Landlord of any such agent or contractor shall be included in any charge to Tenant for such service. Except as provided in the following sentence, any right reserved to Landlord under this Lease may be exercised by Landlord, any of its constituent members, or any agent, contractor or designee of any of them. Any notice, demand, consent or approval which may be given by Landlord under this Lease may be given only by Landlord, any constituent member of Landlord, or any agent or attorney of any of them.

(q) Entire Agreement. This Lease (including all exhibits hereto) contains the entire agreement between Landlord, and Tenant with respect to its subject matter, and all negotiations, considerations, representations, understandings and agreements, oral or written, which may have been previously made between any of the foregoing parties are incorporated and merged into this Lease. In executing and delivering this Lease, Tenant has not relied on any representation, warranty or statement by Landlord, any of Landlord’s constituent members, or any of their respective agents, partners or employees, which is not set forth in this Lease, including without limitation any representation as to the amount of any Additional Rent, or any component thereof, or any representation that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis.

At Landlord’s request, Tenant shall deliver to Landlord, within thirty days after the end of each fiscal quarter, and within ninety (90) days after the end of each fiscal year, of Tenant, Tenant’s quarterly or annual financial statements, as the case may be, including balance sheets, income statements and cash flow statements, prepared in accordance with generally accepted accounting principles consistently applied.

The captions, Section numbers and Table of Contents appearing in this Lease are inserted only as a matter of convenience and in no way define, limit, construe or describe the scope or intent of such Sections of this Lease nor in any way affect this Lease.

29. SECURITY DEPOSIT.

(a) Tenant has deposited with Landlord the Security Deposit set forth in Section 1(s) hereof as security for the full and faithful performance of every provision of this lease to be performed by Tenant. If Tenant defaults with respect to any provision of this lease, including but not limited to the provisions relating to the payment of Rent, Landlord may use, apply or retain all or any part of the Security Deposit for the payment of any Rent and any other sum in default, or for the payment of any other amount which Landlord may spend or become obligated to spend by reason of Tenant’s default or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s default. If any portion of the Security Deposit is so used or applied, Tenant shall within five (5) days after written demand therefor deposit cash with Landlord or Landlord’s beneficiaries in an amount sufficient to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a material breach of this lease. Except to the extent required by law, Landlord shall not be required to keep the Security Deposit separate from its or their general funds and Tenant shall not be entitled to interest on the Security Deposit. If Tenant shall fully and faithfully perform each and every provision of this lease to be performed by it, the Security Deposit or any balance thereof shall be returned to Tenant (or at Landlord’s option to the last permitted assignee of Tenant’s interest hereunder, if any) within thirty (30) days after the expiration of the lease Term and Tenant’s vacation of the Premises. Landlord may deliver the Security Deposit funds deposited hereunder by Tenant to the purchaser of Landlord’s interest in the Project, in the event that such interest is sold, transferred or conveyed, and thereupon Landlord shall be discharged from any further liability with respect to the Security Deposit.

(b) In lieu of a cash Security Deposit, Tenant may deliver to Landlord a clean, irrevocable, non-documentary and unconditional Letter of Credit issued by and drawn upon any commercial bank, trust company, national banking association or savings and loan association having offices for banking purposes in the City of Chicago and which is a member of the Chicago Clearinghouse association (the “Issuing Bank”) and which (or the parent company of which) shall have outstanding unsecured, uninsured and unguaranteed indebtedness, or shall have issued a letter of credit or other credit facility that constitutes the primary security for any outstanding indebtedness (which is otherwise uninsured and unguaranteed), that is then rated, without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation, “Aa” or better by Moody’s Investors Service and “AA” or better by Standard & Poor’s Corporation, and has combined capital, surplus and undivided profits of not less than $500,000,000.00, which Letter of Credit shall have a term of not less than one year, be in form and content satisfactory to Landlord (and substantially as shown on Exhibit I to this Lease), be for the account of Landlord, be in the amount of the Security Deposit then required to be deposited hereunder, and be fully transferable by Landlord to successor owners of the Building without the payment of any fees or charges, it being agreed that if any such fees or charges shall be so imposed, then such fees or charges, shall be paid by Tenant. The Letter of Credit shall provide that it shall be deemed automatically renewed, without amendment, for consecutive periods of one (1) year each thereafter during the term of this Lease, unless the Issuing Bank sends notice (the “Non-Renewal Notice”) to Landlord by certified mail, return receipt requested, not less than thirty (30) days next preceding the then expiration date of the Letter of Credit that it elects not to have such Letter of Credit renewed. Additionally, the Letter of Credit shall provide that Landlord shall have the right, exercisable upon its receipt of the Non-Renewal Notice, by sight draft on the Issuing Bank, to receive the monies represented by the existing Letter of Credit and in such event, Landlord shall hold such proceeds pursuant to the terms of this Section as a cash security pending the replacement of such Letter of Credit. If a Default shall have occurred and be continuing with respect to any provision of this Lease, including but not limited to the provisions relating to the payment of Rent, Landlord may apply or retain the whole or any part of the cash security so deposited or may notify the Issuing Bank and thereupon receive all the monies represented by the Letter of Credit and use, apply, or retain the whole or any part of such proceeds, as provided in this Section. Any portion of the cash proceeds of the Letter of Credit not so used or applied by Landlord in satisfaction of the obligations of Tenant as to which such Default shall have occurred shall be retained by Landlord as a cash Security Deposit as provided herein. If Landlord applies or retains any part of the cash security or proceeds of the Letter of Credit, as the case may be, Tenant shall, within five (5) days after written demand therefor, deposit with Landlord the amount so applied or retained so that Landlord shall have the full Security Deposit required pursuant to this Section on hand at all times during the Term. If

Tenant shall fully and faithfully comply with all of the term, provisions, covenants and conditions of this Lease, the Letter of Credit shall be returned to Tenant after the Expiration Date and after delivery of possession of the Premises to Landlord. In the event of a sale of Landlord’s interest in the Premises, within thirty (30) days of notice of such sale or leasing, Tenant, at Tenant’s sole cost and expense, shall arrange for the transfer of the Letter of Credit to the new landlord, as designated by Landlord, or have the Letter of Credit reissued in the name of the new landlord and Landlord shall thereupon be released by Tenant from all liability for the return of the Letter of Credit; provided, however, that if the Letter of Credit is reissued, Landlord shall return the original Letter of Credit issued in Landlord’s name to Tenant. In the event Tenant brings any action or proceeding to enforce Landlord’s obligations or determine Landlord’s rights to draw upon an Letter of Credit issued to Landlord hereunder, and as a result of such action or proceeding, a court of competent jurisdiction issues a final, unappealable order or judgment finding that Landlord has drawn upon such Letter of Credit in violation of the provisions hereof, then Tenant shall, subject to the provisions of local law, be entitled to recover from Landlord all reasonable expenses of attorney’s fees, paralegal fees and costs, expenses and disbursements incurred by Tenant in such action or proceeding, without the necessity for a cross-action by Tenant. Such reimbursement shall include all such expenses incurred in connection with any such action or proceeding and at all levels of appeal and post judgment proceedings.

30. INTENTIONALLY DELETED.

31. LANDLORD.

The term “Landlord” as used in this Lease means only the owner of Landlord’s interest in the Premises from time to time. In the event of any assignment, conveyance or sale, once or successively, of Landlord’s interest in the Premises or any assignment of this Lease by Landlord, said Landlord making such assignment, conveyance or sale shall be entirely freed and relieved of all covenants and obligations of Landlord hereunder accruing after such assignment, conveyance or sale to the extent such covenants and obligations are assumed in writing by such assignee, grantee or purchaser or are deemed assumed by such assignee, grantee or purchaser by operation of law, and Tenant agrees to look solely to such assignee, grantee or purchaser with respect thereto. The holder of a Mortgage (or assignment in connection with a Mortgage) shall not be deemed such an assignee, grantee or purchaser under this Section 31 unless and until the foreclosure of the Mortgage or the conveyance or transfer of Landlord’s interest under this Lease in lieu of foreclosure, and then subject to the provisions of Section 20. This Lease shall not be affected by any such assignment, conveyance or sale, and Tenant agrees to attorn to the assignee, grantee or purchaser.

32. TITLE AND COVENANT AGAINST LIENS.

Landlord’s title is and always shall be paramount to the title of Tenant, and nothing in this Lease contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord. Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon Landlord’s title or interest in the Premises or any part of the Project, and any and all liens and encumbrances created by Tenant shall attach to Tenant’s interest only.

33. COVENANT OF QUIET ENJOYMENT.

Landlord agrees that Tenant, on paying the Rent and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Term, peaceably and quietly have, hold and enjoy the Premises, subject to the terms, covenants, conditions, provisions and agreements of this Lease, free from hindrance by Landlord or any person claiming by, through or under Landlord.

34. EXCULPATORY PROVISIONS.

The liability of any Landlord under this Lease or any amendment to this Lease, or any instrument or document executed in connection with this Lease, shall be limited to and enforceable solely against the assets of such Landlord constituting an interest in the Land or Building and not other assets of such Landlord. Assets of a Landlord which is a partnership or

limited liability company do not include the assets of the partners or members of such Landlord, and any negative capital account of a partner or member in a partnership or limited liability company which is a Landlord, and any obligation of a partner or member to contribute capital to the partnership or limited liability company which is Landlord, shall not be deemed to be assets of the partnership or limited liability company which is the Landlord. No directors, officers, employees, managers, members, or shareholders of any corporation or limited liability company which is Landlord shall have any personal liability arising from or in connection with this Lease. At any time during which Landlord is trustee of a land trust, all of the representations, warranties, covenants and conditions to be performed by it under this Lease or any documents or instruments executed in connection with this Lease are undertaken solely as trustee, as aforesaid, and not individually, and no personal liability shall be asserted or be enforceable against it or any of the beneficiaries under said trust agreement by reason of any of the representations, warranties, covenants or conditions contained in this Lease or any documents or instruments executed in connection with this Lease.

Tenant shall accept possession of the Temporary Expansion Space in its then “as is” condition. No agreement of Landlord to alter, remodel, decorate, clean or improve the Temporary Expansion Space and no representation or warranty regarding the condition of the Temporary Expansion Space of any kind or nature has been made by or on behalf of Landlord to Tenant under or by reason of this Lease. The Temporary Expansion Space shall be subject to all the terms and provisions of this Lease except that Tenant shall not be obligated to pay Base Rent or Tenant’s Proportionate Share of Expenses and Taxes with respect thereto. Tenant shall be entitled to use and occupy the Temporary Expansion Space until thirty (30) days after the Expansion Effective Date (the “Temporary Expansion Termination Date”). On or before the Temporary Expansion Termination Date, Tenant shall comply with the provisions of Section 35(b) below as if the Temporary Expansion Termination Date were the Reduction Effective Date thereunder and the Temporary Expansion Space were the Reduction Space thereunder.

Any retention of possession by Tenant of all or part of the Reduction Space after the Reduction Effective Date shall be deemed a holding over under Section 11 of this Lease without consent of Landlord, and shall be subject to the terms and conditions of said Section with respect to such holdover. Notwithstanding anything contained herein to the contrary, in no event shall Tenant be released from or relieved of any liability with respect to the Reduction Space accruing under this Lease prior to the Reduction Effective Date (including, without limitation, the obligation to perform any other conditions and covenants that by the terms of this Lease as it pertains to the Reduction Space survive the termination of this Lease) or of any Default under this Lease that occurred prior to the Reduction Effective Date or which would have constituted a Default as of the Reduction Effective Date except for the passage of time. Tenant hereby represents and covenants that it has not at any time done or suffered any act or omission and will not do or suffer any act or omission whereby the Reduction Space or any part thereof are or may be in any way charged, assessed or encumbered.

Notwithstanding anything to the contrary contained in this Lease (including, without limitation, Section 15 hereof), Tenant’s signage rights under this Section 38(b) shall not be assignable or subleasable by Tenant to any other party.

39. INTERNAL STAIRWELL.

Notwithstanding anything to the contrary contained in this Lease, upon expiration or earlier termination of this Lease or Tenant’s right to possession of the Premises, Tenant shall have no obligation to remove the internal stairwell between the 17^th and 18^th floors of the Premises installed as part of Landlord’s Work under this Lease nor to restore the ceiling and/or structural floor in the opening therefor.

40. ADDITIONAL SERVICES REQUIREMENTS.

Landlord shall use commercially reasonable efforts to provide riser space, electrical power and HVAC service to meet Tenant’s on-going requirements for the operation of its business in the Premises, provided that all costs, fees and expenses of design, engineering, permits and approvals, alterations to the Building, and purchase, installation, operation, repair, maintenance replacement and removal of any and all conduit, cabling, ductwork and equipment to provide same shall be at Tenant’s sole cost and expense. In addition, Landlord may charge Tenant for any additional services or riser space provided by Landlord in connection with the foregoing at the Building standard rates in effect from time to time. As to Landlord’s obligations to furnish riser space hereunder, the term “commercially reasonable efforts” shall include, without limitation, provision of then-available space within existing risers and/or removal of then-unused conduit, cabling, ductwork and equipment from the existing risers to make additional space available for Tenant’s use (subject to Tenant’s obligation to pay such removal and other related costs as provided herein) but shall not include any obligation of Landlord to shut down, close off, make unavailable or otherwise alter or impair any of the Building’s systems or common areas, except on a limited and temporary basis, in order to furnish such riser space.

41. OPTION TO EXTEND.

(a) Provided this Lease is in full force and effect and that no Default by Tenant, as defined in this Lease is in existence either on the date of Tenant’s Extension Notice (as hereinafter defined) or, unless waived in writing by Landlord for the purpose of this Extension Option (as hereinafter defined), on the Extension Effective Date, and provided further that this Lease shall not have theretofore been assigned (other than pursuant to an assignment not requiring Landlord’s consent thereto), Tenant shall have the right, at Tenant’s option, to extend the Term of this Lease for one (1) additional period of five (5) years (the “Optional Extended Term”) commencing on the day following the Expiration Date (the “Extension Effective Date”) and ending on the fifth (5^th) anniversary of the Expiration Date. Such option to extend (the “Extension Option”) shall be exercised by Tenant giving written notice (“Tenant’s Extension Notice”) of the exercise thereof to Landlord at least eighteen (18) but not more than twenty-one (21) months before the Expiration Date. If Tenant shall fail to timely give Tenant’s Extension Notice as provided herein, the Extension Option shall be deemed automatically and irrevocably waived by Tenant. The Term as extended pursuant to the Extension Option shall be upon the same terms, covenants, and conditions as set forth in this Lease except that the Base Rent payable during the Optional Extended Term, if exercised, shall equal the Market Rate (as defined below). In the event Tenant exercises the Extension Option as provided herein, then Tenant shall, within fifteen (15) days after Landlord’s request, execute and deliver an amendment to the Lease memorializing such exercise and the Rent payable by Tenant during the Optional Extended Term.

(b) For purposes of this Article, “Market Rate” shall mean the rate then being accepted by landlords for comparable improved space in the Development and in office buildings comparable thereto in the West Loop submarket of the downtown Chicago office market on an “as is” renewal basis for a comparable term, taking into account the use, location and floor level within the applicable building, and any other relevant term or condition in making such evaluation, including any tenant improvement allowances or other leasing concessions offered in connection therewith, all as reasonably determined by Landlord and provided to Tenant in writing within thirty (30) days after the date of delivery of Tenant’s Extension Notice to Landlord (“Landlord’s Market Rate Notice”).

(c) If Tenant disputes Landlord’s determination of the Market Rate, then Tenant shall notify Landlord in writing within fifteen (15) days after the date of delivery of Landlord’s Market Rate Notice to Landlord that Tenant objects to Landlord’s determination and in such notice Tenant shall state its determination of the Market Rate. Landlord and Tenant shall, during the fifteen (15) day period after Tenant’s notice to Landlord of such objection, attempt in good faith to agree on the Market Rate. If Landlord and Tenant are unable to agree, Tenant shall either (i) accept Landlord’s determination of Market Rate or (ii) submit the determination to binding arbitration as provided herein. If Tenant fails to so notify Landlord of Tenant’s election under the preceding sentence within said fifteen (15) day period, Tenant shall be deemed to have accepted Landlord’s determination. If Tenant elects to submit the determination of the Market Rate to arbitration, Landlord and Tenant shall each select an arbitrator within fifteen (15) days after Tenant’s election to arbitrate. If either Landlord or Tenant fail to timely appoint an arbitrator, the arbitrator selected shall select the second (2^nd) arbitrator, who shall be impartial, within fifteen (15) days after such party’s failure to appoint. Each arbitrator must be a licensed real estate broker and have at least ten (10) years experience in the downtown Chicago, Illinois market in the leasing of properties which are similar in character to the Building. The two arbitrators shall, within twenty (20) days of their appointment, select from the two determinations submitted by Landlord and Tenant the one that is closer to the Market Rate as determined by the arbitrators, and said selection shall thereafter be deemed the Market Rate. If the two arbitrators so appointed fail to agree as to which of the determinations submitted by Landlord and Tenant is the closest to the actual Market Rate, the two arbitrators shall appoint a third arbitrator within twenty (20) days after the failure of the initial arbitrators to agree on a Market Rate, to decide upon which of the two determinations submitted is the closest to the actual Market Rate. The arbitrators shall not be permitted to choose as the Market Rate any determination other than the determination presented by either Landlord or Tenant. The fees and expenses of any arbitration shall be borne by the losing party. The arbitrators’ determination shall be final and binding on the parties. If the Market Rate has not been determined by the Extension Effective Date, Tenant shall pay the Market Rate as determined by Landlord until

such time as the arbitrators are able to determine the Market Rate. Upon such determination, Rent for the Premises shall be retroactively adjusted to the Extension Effective Date. If such adjustment results in an underpayment of Rent by Tenant, Tenant shall pay Landlord the amount of such underpayment within twenty (20) days after the determination thereof. If such adjustment results in an overpayment of Rent by Tenant, Landlord shall credit such overpayment against the next installment of Rent due under the Lease and, to the extent necessary, any subsequent installments until the entire amount of such overpayment has been credited against Rent.

E. Tenant agrees that it will not unreasonably withhold its approval of the Tenant Plans or any revised Tenant Plans required hereunder. Landlord agrees that it will not unreasonably withhold its approval of the Tenant Plans or any revised Tenant Plans required hereunder, or any Change or modified Change permitted hereunder provided, however, Landlord shall not be deemed to have acted unreasonably if it withholds its consent because, in Landlord’s opinion, any portion of Landlord’s Work or Landlord’s Additional Work covered by the Tenant Plans or any revised Tenant Plans required hereunder, or any such Change (i) is likely to adversely affect the structural, mechanical, electrical, plumbing, HVAC, life safety, communications, security or other operating systems of the Building or the safety of its occupants, (ii) would increase the costs or expenses incurred by or on behalf of Landlord for owning, managing, operating, maintaining or repairing the Building (in which event, Landlord shall furnish Tenant with reasonable supporting documentation thereof), (iii) would impair Landlord’s ability to furnish services to Tenant or any other tenant of the Building, (iv) would violate any Laws or provisions of the Tenant Lease as amended by this Lease, (v) would adversely affect the appearance of the Building, (vi) would adversely affect the premises of any other tenant of the Building or such tenant’s use or occupancy thereof, (vii) is prohibited by the provisions of any mortgage or ground lease encumbering the Building, or (viii) materially fails to conform to either Building standards or the current build-out of the Original Premises and/or the 20^th floor portion of the Building presently leased by Townsend Analytics, Ltd., with respect to design, character, materials or finishes except as otherwise expressly provided herein. The foregoing reasons shall not be exclusive of the reasons for which Landlord may withhold consent, it being understood and agreed that such other reasons may be similar or dissimilar to the foregoing.

F. The cost of the Tenant Plans and any revisions thereof required hereunder shall be deemed to be part of the cost of Landlord’s Work to be paid as provided in Paragraph 4 below.

Landlord shall not cause Landlord’s Contractor to commence any work necessary to incorporate a Change into Landlord’s Work or Landlord’s Additional Work, as applicable, until Tenant has approved Landlord’s estimate of the cost of such work and the number of days of Tenant Delay that may result from such work, which approval may be withheld by Tenant in its sole and absolute discretion.

3. Performance of Landlord’s Work and Landlord’s Additional Work.

A.

4. Payment for Landlord’s Work and Landlord’s Additional Work.

A. Landlord’s Work. Except as otherwise provided herein, Landlord shall pay the aggregate cost of Landlord’s Work and Tenant shall pay the Initial Excess as increased or decreased, as the case may be, by any aggregate net increase or decrease in the cost of Landlord’s Work resulting from any and all Changes approved or deemed approved by Tenant hereunder (collectively, the “Landlord’s Work Excess”), plus the cost of all work other than Landlord’s Work and Landlord’s Additional Work, if any, which Tenant may elect to do in order to make the Expansion Space ready for Tenant’s occupancy and which has been approved by Landlord pursuant to Paragraph 6E below. Tenant shall pay the Landlord’s Work Excess as provided in Paragraph 4C below, and Tenant shall pay the cost of such other work, if any, directly to the persons or entities performing such other work. The “cost of Landlord’s Work” as used in this Workletter shall include all costs incurred by Landlord to plan, design and perform Landlord’s Work as specified by the Tenant Plans and any approved (or deemed approved) revisions thereof (including any Change), including without limitation, the fees and charges of Landlord’s Architect, Landlord’s Engineer and Landlord’s Contractor, all permit and inspection fees and charges, and any costs incurred by or charged to Landlord for (i) unforeseen field conditions, (ii) substitution of materials or finishes due to the unavailability of materials or finishes specified in the Tenant Plans (as revised) that would materially delay substantial completion of Landlord’s Work, (iii) necessary modification of any portions of the Building or its systems to accommodate Landlord’s Work, and (iv) any Change to comply with applicable laws, regulations, codes or ordinances and/or the requirements of any building inspector with jurisdiction over Landlord’s Work.

B. Landlord’s Additional Work. Landlord shall pay the aggregate cost of Landlord’s Additional Work up to an amount not to exceed the Landlord’s Additional Work Allowance and Tenant shall pay the excess of the aggregate cost of Landlord’s Additional Work over the Landlord’s Additional Work Allowance (the “Landlord’s Additional Work Excess” and collectively with the Landlord’s Work Excess, if any, the “Excess”). Tenant shall pay the Landlord’s Additional Work Excess as provided in Paragraph 4C below. The “cost of Landlord’s Additional Work” as used in this Workletter shall include all costs incurred by Landlord to plan, design and perform Landlord’s Additional Work and any approved (or deemed approved) revisions thereof (including any Change), including without limitation, the fees and charges of Landlord’s Architect, Landlord’s Engineer and Landlord’s Contractor, all permit and inspection fees and charges, and any costs incurred by or charged to Landlord for (i) unforeseen field conditions, (ii) substitution of materials or finishes due to the unavailability of materials or finishes that would materially delay substantial completion of Landlord’s Work, (iii) necessary modification of any portions of the Building or its systems to accommodate Landlord’s Additional Work, and (iv) any Change to comply with applicable laws, regulations, codes or ordinances and/or the requirements of any building inspector with jurisdiction over Landlord’s Additional Work. Landlord shall, upon presentation of paid invoices therefor, reimburse Tenant for the out-of-pocket fees and charges of Tenant’s

B-5

interior space planner incurred and paid by Tenant in connection with Landlord’s Work and Landlord’s Additional Work, and the amount of such reimbursement shall be included as part of the cost of Landlord’s Additional Work in determining if there is an Excess. If the aggregate total cost of Landlord’s Additional Work is less than the Landlord’s Additional Work Allowance, any remaining unused portion of the Landlord’s Additional Work Allowance which is not applied against any Landlord’s Work Excess as provided in Paragraph 4C below, shall be credited against the next then due installments of Base Rent due from Tenant under this Lease.

C. Excess. If Landlord estimates at any time or from time to time that there will be an Excess, Landlord shall notify Tenant in writing of Landlord’s good faith estimate of the amount thereof, which estimate shall be itemized in reasonable detail. Landlord shall cooperate with Tenant to clarify the basis for any such estimate, including providing reasonable supporting documentation therefor upon Tenant’s written request. Tenant shall, within ten (10) business days after it receives Landlord’s bill therefor, either (i) pay one-half (1/2) of Landlord’s good faith estimate of the Excess billed by Landlord or (ii) notify Landlord in writing that Tenant elects to have Landlord pay the Excess as provided below. In the event Tenant fails to timely pay or notify Landlord of Tenant’s election to have Landlord pay any such Excess, Landlord shall be entitled to suspend the performance of Landlord’s Work and Landlord’s Additional Work until such time as such payment or election is received by Landlord. At such time as the total cost of the Tenant Plans, Landlord’s Work and Landlord’s Additional Work is finally determined, Landlord shall notify Tenant of such amount in writing. If Tenant has not paid all of the Excess, such notice shall include Landlord’s bill to Tenant for the balance of the Excess not previously paid by Tenant, and if Tenant has paid more than the Excess, such notice shall include Landlord’s statement to Tenant showing the amount of the overpayment of the Excess. Tenant shall pay any such balance of the Excess to Landlord within ten (10) business days after the date when Tenant receives such notice and bill from Landlord, and Landlord shall pay any such overpayment of the Excess to Tenant within ten (10) business days after the later of the date when Landlord gives such notice and statement to Tenant or the Expansion Effective Date. All Landlord’s bills to Tenant for portions of the Excess and Landlord’s notice to Tenant of the finally determined cost of the Tenant Plans and Landlord’s Work and Landlord’s Additional Work shall itemize the costs in question in reasonable detail. In the event of Tenant’s written notice requesting Landlord to pay the Excess as provided above, Landlord shall pay the Excess (in an amount not to exceed $100,000 in the aggregate (the “Excess Amortization Cap”)) and in such event, (i) the amount of Monthly Base Rent payable by Tenant under this Lease shall be increased by the monthly amount as reasonably determined by Landlord as being necessary to fully amortize such Excess paid by Landlord on an equal payment basis over the period commencing on the Expansion Effective Date and ending on the Expiration Date using an amortization interest rate equal to ten percent (10%) per annum, (ii) thereafter upon Landlord’s request, Tenant shall enter into an amendment to the Tenant Lease memorializing such increase in the Monthly Base Rent and (iii) any portion of the Excess exceeding the Excess Amortization Cap shall be paid by Tenant to Landlord as provided herein. In addition, if upon final completion of Landlord’s Additional Work there remains any unused portion of the Landlord’s Additional Work Allowance and there is any Landlord’s Work Excess, then such unused portion of the Landlord’s Additional Work Allowance shall be applied to reduce (or eliminate) the Landlord’s Work Excess, and any remaining unused portion of the Landlord’s Additional Work Allowance after such application shall be credited against Base Rent as provided in Paragraph 4B above.

Commencing on the first anniversary of the Storage Space Commencement Date and on each succeeding anniversary thereof during the Storage Space Term, the Storage Space Fee shall increase by Sixty-Three and 96/100 Dollars ($63.96) per month over the Storage Space Fee payable during the preceding year.

F-1

person, property or business or for loss or interruption of business, or for any other matter, in the event there is any failure, delay, interruption or diminution in furnishing any service to the Storage Space. No such failure, delay, interruption or diminution shall be deemed to constitute an eviction or disturbance of Licensee’s use or possession of the Storage Space, in whole or in part, actual or constructive, nor entitle Licensee to any claim for set-off, abatement or reduction of the Storage Space Fee, nor render Licensor liable for damages, nor relieve Licensee from the performance of or affect any of Licensee’s obligations under this Agreement. However, Licensor shall use commercially reasonable efforts to minimize any such failure, delay, interruption or diminution.

Licensee shall use the Storage Space in accordance with and shall comply with all applicable laws, ordinances, orders and regulations relating to the use, condition and occupancy of the Storage Space and with Licensor’s rules, regulations and directions which may be established from time to time (including, without limitation, any and all rules and regulations established by or under the Lease as if the Storage Space were the Premises thereunder). Licensee agrees that Licensor or its agents or representatives may enter into and upon any part of the Storage Space to inspect the same, clean or make repairs, alterations or additions to the Storage Space or the Building, without such acts being deemed an eviction of Licensee or breach of quiet enjoyment, and Licensee shall not be entitled to any abatement or reduction of the Storage Space Fee by reason thereof. Licensee shall furnish Licensor with all keys to the Storage Space.

7. Indemnity; Waiver. Licensee shall not permit any mechanic’s, materialman’s or other liens to be placed upon or against the Storage Space or the real estate upon which the Storage Space is located.

Licensee agrees to defend, indemnify and hold harmless Licensor from any and all loss, cost, injury claims, actions, damages, expenses or liens resulting, directly or indirectly, from (a) Licensee’s exercise of rights granted under this License Agreement, (b) the breach of the aforesaid representation, warranty and covenant or default on the part of Licensee in the performance of its obligations hereunder, (c) any act, neglect, or omission of Licensee, and Licensee’s agents, contractors, officers, employees. Licensor shall not be liable to Licensee, its agents, servants, employees, customers or invitees for any injury to persons or damage to property in the Storage Space. Licensor and Licensee waive any rights each may have against the other from any risk generally covered by fire and extended coverage and, on behalf of their insurance companies, waive any right of subrogation which such insurer may have against the parties hereto. The foregoing provisions expressly exclude any agreement of Licensee to indemnify or waive claims against Licensor or its employees or agents due to negligence in the operation or maintenance of the Building. Licensee’s agreements and obligations under this Section shall survive the expiration or early termination of this Storage License Agreement.

Any amounts payable by Licensee hereunder which are not paid on or before the date due shall bear interest from the date due until paid at an annual rate equal to the Default Rate (as defined in the Lease) or such lesser rate which shall then be the maximum rate permitted by law with respect thereto.

11. Miscellaneous. Licensee hereby acknowledges that in no event shall Licensor be responsible or liable to Licensee for any damage to or loss of property placed or otherwise stored in the Storage Space.

5. Lessee agrees with Lender that from and after the date hereof, Lessee will not terminate or seek to terminate the Lease by reason of any act or omission of the Lessor thereunder until Lessee shall have given written notice, by registered or certified mail, return receipt requested, of said act or omission to Lender, which notice shall be addressed to Massachusetts Mutual Life Insurance Company, c/o David L.
