Tenant shall deposit into the Tax Escrow any such shortfall amount within thirty (30) days of Landlord’s request. If Tenant fails to pay to Landlord Tenant’s Proportionate Share - Office Tower of Taxes for the Office Tower and Tenant’s Proportionate Share Taxes - Retail Space of Taxes for the Retail Space for the Calendar Year when due as provided herein, Landlord may apply the Tax Escrow to the amount of Taxes owed by Tenant.

Proportionate Share Taxes - Retail Space of Taxes for the Retail Space for Taxes which have accrued in the Calendar Year in which the Termination Date occurs through the Termination Date. Landlord shall use the Tax Escrow for the payment of Tenant’s share of Taxes for the final Calendar Year of the Term and shall pay any excess remaining in the Tax Escrow (and any interest earned thereon) to Tenant within thirty (30) days. If Tenant’s share of Taxes for the final Calendar Year of the Term exceeds the amount held in the Tax Escrow, Tenant shall, within thirty (30) days after the written request of landlord, pay such excess to Landlord. Notwithstanding anything to the contrary contained herein, Tenant shall pay Tenant’s Proportionate Share Taxes - Office Tower of 1997 Taxes for the Office Tower and Tenant’s Proportionate Share Taxes - Retail Space of 1997 Taxes for the Retail Space for the entire Calendar Year 1997, regardless of when the Commencement Date of this Lease actually occurs. Tenant also agrees that it shall remain responsible for Tenant’s Proportionate Share Taxes - Office Tower and Tenant’s Proportionate Share Taxes - Retail Space for any Contraction Space with respect to which Tenant has exercised its option under Section 31 for the Calendar Year in which such Contraction Space is vacated by Tenant through the applicable Contraction Date, although payable in the subsequent Calendar Year.

Landlord agrees to keep true and accurate records of all Operating Expenses. Prior to May 1 of each Calendar Year, Landlord shall submit to Tenant a detailed statement certified by a certified public accountant (the TM Statement”) setting faith (A) the actual amount of Operating Expenses and Taxes for the previous Calendar Year, (B) the amount of Tenant’s Expense Participation Amount on account of such previous Calendar Year and (C) the payments made by Tenant on account thereof. If the installments made on account of such previous Calendar Year exceed Tenant’s Expense Participation Amount due on account of such Calendar Year, as shown on the Operating Statement, such excess shall be credited by Landlord against the next succeeding installment(s) of Tenant’s Expense Participation Amount; provided if Tenant is not in default under this Lease, Landlord shall at Tenant’s request refund such excess to Tenant within thirty (30) days of such request. If, however, said installment(s) are less than Tenant’s Expense Participant Amount due on account of such Calendar Year, as shown on the Operating Statement, then Tenant agrees to pay to Landlord the amount necessary to make up any deficiency within thirty (30) days after the delivery of the Operating Statement to Tenant.

C. Miscellaneous re Additional Rent. If the date the Term commences is not the first day of a Calendar Year, or if the date of expiration or termination of this Lease is not the last day of a Calendar Year, the Tenant’s Expense Participation Amount shall be prorated based upon the number of days of the applicable partial Calendar Year within the Term.

Every Operating Statement given by Landlord pursuant to Paragraph 5.B shall be conclusive and binding upon Tenant unless (i) Tenant shall notify Landlord that it disputes the correctness of the then current Operating Statement or Operating Statements from the previous two (2) years, specifying the particular respects in which the Operating Statement is claimed to be incorrect, and (ii) if such dispute shall not have been settled by agreement, it shall be settled by submission of such dispute to a national public accounting firm acceptable to Landlord and Tenant, at the expense of Tenant, except as hereinafter provided, for a final and binding determination. Pending the determination of such dispute, Tenant shall within thirty (30) days after receipt of such Operating Statement, pay any deficiency in Tenant’s Expense Participation Amount payment if due in accordance with the Operating Statement, and such payment shall be

without prejudice to Tenant’s position. If the dispute shall be determined in Tenant’s favor, Landlord shall, on demand, pay Tenant the amount of Tenant’s overpayment of Tenant’s Expense Participation Amount, if any, resulting from compliance with the Operating Statement. If the discrepancy was greater than two percent (2%) of the correct Operating Statement, Landlord shall pay to Tenant interest on such overpayment at the rate of two percent (2%) per annum over the Prime Rate. Landlord agrees to grant Tenant reasonable access to Landlord’s books and records, during normal business hours, at Landlord’s office, for the purpose of verifying Operating Expenses incurred by Landlord, and to make copies of any and all bills and vouchers relating thereto, subject to reimbursement by Tenant for the cost of such copies.

In the event that a review of landlord’s books and records pursuant to this Paragraph 5 reveals that Landlord his overstated its Operating Expenses for the applicable Calendar Year by 3% or more of the actual Operating Expenses incurred for such Calendar Year, Landlord shall also reimburse Tenant for the reasonable expenses incurred by Tenant in conducting such review of Landlord’s books and records and for the amounts paid to the public accounting firm. In the event that there is an error of less than 3% in Landlord’s statement of the Operating Expenses, then Tenant shall pay the cost of the public accounting firm.

If Tenant’s requirements for electricity are in excess of those set forth in this clause (2) the Landlord reserves the right to require Tenant to pay the cost of installation, operation and maintenance of the conduit, wiring and other equipment necessary to supply electricity for such excess use requirements at the Tenant’s expense by arrangement with Commonwealth Edison Company or another approved local utility.

Notwithstanding the foregoing, Landlord shall not decrease the level of quality of services provided to Tenant as of the date hereof.

B. Billing for Electricity. Tenant shall pay for the use of all electrical service to the Premises. Provided that Landlord can make satisfactory arrangements with the utility company supplying electricity to the Premises for separate metering and billing, Tenant shall be

billed directly by such utility company. In the event that for any reason the Premises are metered, but Tenant cannot be billed directly, Landlord shall forward each ▇▇▇▇ received by it with respect to the Premises to Tenant and Tenant shall pay it promptly in accordance with its terms.

Landlord has advised Tenant that presently Commonwealth Edison (the “Electric Service Provider”) provides electricity service to the Building. Notwithstanding the foregoing, if permitted by law, Landlord shall have the right at any time and from time to time during the Term of this Lease to either contract for electricity service from a different company or companies providing electricity service (each such company, an “Alternate Service Provider”) or continue to contract for electricity service from the Electric Service Provider; provided, however, that all Alternate Service Providers selected by Landlord shall provide electricity service to the Building and Premises at a level which is identical or better than the electricity service provided by the Electric Service Provider and such new electricity service will not increase Tenant’s electricity costs.

If the Landlord ceases to furnish any of the services referred to in this Paragraph 7 and if (i) as a result of such cessation, the Premises, or any floor within the Premises, is rendered untenantable (meaning Tenant’s inability to use any or all of the floor(s) (or any part thereof) within the Premises in the normal course of its business) and (II) such cessation continues for a period of three (3) business days, then, the Rent payable hereunder shall be equitably abated based upon the percentage of the space in the Premises so rendered untenantable and not then being used by Tenant in the ordinary course of Its business operations. The foregoing abatement shall become effective as of the first business day following the day the affected floor(s) become(s) untenantable. Landlord agrees to use all commercially reasonable efforts to cure the cessation of service(s) as promptly as reasonably practicable. Tenant agrees to cooperate with Landlord in abiding by all reasonable rules and regulations that Landlord prescribes for proper functioning of utilities and Building services. Tenant agrees not to tamper or adjust any utilities or associated equipment unless authorized in writing by Landlord.

D. Charges for Services.

E. Energy Conservation. Notwithstanding anything to the contrary in this Paragraph 7 or elsewhere in this Lease, if the federal government, the State of Illinois or the City

Nothing contained in this Paragraph 8 shall require Landlord to paint or decorate the Premises. If the Landlord does not commence any required maintenance, repair or replacement within thirty (30) days of the request of Tenant to do so (or in cases of emergency within twenty-four (24) hours after notice), or if after such commencement, Landlord does not thereafter diligently pursue same to completion, Tenant may, but need not, make such repairs and replacements, and Landlord shall pay Tenant the cost thereof within ten (10) days after notice given from Tenant to Landlord specifying such costs.

Except as expressly otherwise provided in this Lease, Landlord shall have no liability to Tenant by reason of any inconvenience, annoyance, interruption or injury to business arising from Landlord’s making any repairs or changes which Landlord is required or permitted by this Lease, or required by law, to make in or to any portion of the Building or the Premises, or in or to the fixtures, equipment or appurtenances of the Building or the Premises, provided that Landlord shall use due diligence with respect thereto. In case of repairs or changes which are made within the Premises, unless such repairs, renewals or improvements can be made during business hours without material interference with Tenant’s business operations, Landlord shall make such repairs, alterations, or replacements during non-business hours, except in the event of an emergency.

B. All changes, whether temporary (to the extent then existing) or permanent in character, made or paid for by Landlord or Tenant, shall without compensation to Tenant become Landlord’s property at the termination of this Lease by lapse of time or otherwise. Tenant shall remove any Structural Changes and restore the Premises to their condition existing prior to such Structural Changes on or before the termination of this Lease if Landlord notified Tenant at the time Landlord approved the making of such Structural Changes that Landlord required such removal.

If the taking is of less than substantially all of the Project or is for a period of less than the aforesaid year, then notwithstanding the foregoing grammatical paragraph, Landlord and Tenant shall have the right to terminate this lease in the following circumstances:

A. Landlord may terminate if in Landlord’s reasonable business judgment restoration of the Project to substantially the same size and quality is not economically justified;

B. Tenant may terminate if (1) more than twenty-five percent (25%) of the Premises is so taken by eminent domain and (2) within sixty (60) days after such taking Landlord has not been able to provide other comparable space in the Building to temporarily add to the Premises to restore the size of the Premises to at least eighty-five percent (85%) of its Rentable Area prior to such taking and Landlord will not, based on Landlord’s estimate of the Rentable Area of the restored Building (such estimate to be delivered to Tenant not more than forty-five (45) days after such taking), be able to restore the Premises to 100% of their Rentable Area prior to such taking by a date not more than one year after the date of such taking. Landlord shall not be bound to offer Tenant more than Tenant’s Proportionate Share (based on the Premises compared to the Building prior to such taking) of the restored Building, and if Tenant fails to terminate this Lease as provided herein, the size of the Premises and the Rent shall be reduced to such share of the restored Building;

C. Either Landlord or Tenant may terminate if the taking occurs within twenty-four (24) months prior to the then effective termination date of the Term, as it may have been extended.

In any of the above termination cases, such termination notice must be given not more than sixty (60) days after the taking (the taking for purposes of this Paragraph shall be the date when the taking authority requires possession) and termination must be effective for the portion not taken not less than thirty (30) or more than ninety (90) days after such notice is given. For the portion taken, the termination shall be effective as of the date of the taking. No money or other consideration shall be payable by the Landlord to the Tenant in the case of termination under any of the above provisions, and Tenant shall have no right to share in the condemnation award except that Tenant shall have the right to recover out of the award all costs and expense incurred by Tenant in moving to other space and the amount of the unamortized cost of all improvements and additions located in the Premises (not including the Allowance contributed by Landlord).

Except as provided in Paragraph 16.B., the word “assignment” in this Paragraph shall mean a 100% assignment. The term “sublease” and all words derived therefrom, as used in this Paragraph 16, shall include any subsequent sublease or assignment under such sublease. Notwithstanding anything to the contrary contained herein, Landlord’s approval of any sublease

by Tenant pursuant to (iii) above shall be limited to Landlord’s reasonable approval of the identity of the proposed subtenant, and the approval conditions listed in the final sentence of the following paragraph.

Landlord’s election to accept any assignee or subtenant as the tenant hereunder and to collect rent from such assignee or subtenant shall not release Tenant or any subsequent tenant from any covenant or obligation under this Lease except as may be expressly provided in Landlord’s written consent Landlord’s consent to any assignment, subletting or transfer shall not constitute a waiver of Landlord’s right to withhold its consent to any future assignment, subletting or transfer, including assignment, subletting or transfer by any subtenant. Landlord may condition its consent upon execution by the subtenant or assignee of an instrument confirming such restrictions on further subleasing or assignment and joining in the waivers and indemnities made by Tenant hereunder. To obtain the consent of Landlord to an assignment or subletting, Tenant shall submit to Landlord at least thirty (30) days prior to the proposed effective date of the assignment or sublease a written notice thereof. Landlord shall not be deemed to have unreasonably withheld its consent to a proposed sublease or assignment if its consent is withheld because: (1) Tenant is then in default hereunder (beyond any applicable cure period); (2) any notice of termination of this Lease or termination of Tenant’s possession shall have been given pursuant hereto and the matter or occurrence giving rise to such notice has not been cured; (3) the proposed sublease or assignment will, as proposed, violate any city, stare or federal law, ordinance or regulation; (4) the proposed use of the Premises by the subtenant or assignee does not conform to the use set forth in Paragraph 6 hereof; or (5) the proposed subtenant or assignee is engaged in a business that would be deleterious to the reputation of the Building.

B. Landlord shall be deemed to approve of any assignment or sublease (however Tenant shall notify Landlord of such assignment or sublease) to: (1) any party resulting from a merger or consolidation with Tenant so long as Tenant or any Affiliate (as hereinafter defined) is the surviving dominant party after such merger (ii) any party succeeding to the business and assets of Tenant; or (iii) any Affiliate of Tenant. For purposes of this Lease, an “Affiliate” shall mean any firm, person, corporation or entity now or hereafter controlling, controlled by or under common control with Tenant and such control is exercised via the ability to direct or cause the direction of, the management and policies of the other, whether through the ownership of voting securities, common directors or officers, or otherwise. At any time during the Term of this tease if Tenant transfers all or a part of Tenant’s United States business operations as of October 1, 1997 (the “U.S. Business”) to an Affiliate or any other firm, person, corporation or entity (collectively, a “Successor Entity”), such Successor Entity shall be made a party to this Lease and shall be jointly responsible with Tenant for all obligations under this Lease. The previous sentence shall apply to any transferee of any such Successor Entity, unless Tenant or any Successor Entity provides Landlord with reasonably acceptable credit documentation evidencing Tenant’s and any Successor Entity’s financial capacity to perform their obligations under this Lease.

C. If at any time Tenant subleases (each sublease, a “Tenant Sublease”) to a total of 200,000 square feet of space in the Premises, “Sublease Profits” (as defined in Paragraph 16.1).) shall be allocated in the following manner:

(i) If there is 150,000 or more RSP then available for lease in the Building at the time of execution of a Tenant Sublease, Landlord and Tenant shall divide Sublease Profits between them equally.

(ii) If there is less than 150,000 RSF then available for lease in the Building at the time of execution of a Tenant Sublease, Tenant shall retain 100% of all Sublease Profits.

Notwithstanding the foregoing, if Tenant subleases more than 200,000 square feet of space in the Premises, the Sublease Profits for the portion of such space above 200,000 square feet shall be equally divided between Landlord and Tenant, regardless of the amount of vacant space in the Building at the time of the sublease. Calculations of Sublease Profits and sublease RSF percentage limitations shall be made on a monthly basis throughout the Term.

D. “Sublease Profits” shall mean the entire excess, after deduction of all reasonable costs of subletting (including, without limitation, marketing costs, rent concessions, reasonable attorneys’ fees, commissions and tenant improvement allowances), of revenues generated by the subleasing of the Premises or portions thereof over the Rent applicable thereto. All such revenues shall be applied first to reimbursement of such costs of subletting until they are paid in full. Not more than thirty (30) days after the commencement date of a sublease which will produce Sublease Profits and annually thereafter, Tenant shall furnish Landlord with a sworn statement setting forth in detail the computation of the Sublease Profits on such sublease (which computation shall be based upon generally accepted accounting principles).

Every such statement shall be conclusive and binding upon Landlord as to the Sublease Profits paid prior to the date of such statement unless within thirty (30) days after the

receipt of such statement, Landlord shall notify Tenant that it disputes the correctness of the statement, specifying the particular respects in which the statement is claimed to be incorrect. If such dispute shall not have been settled by agreement within thirty (30) days after delivery of Landlord’s dispute notice, it shall be settled by submission of such dispute to a national public accounting firm acceptable to Landlord and Tenant, at the expense of Landlord, except as hereinafter provided, for a final and binding determination. Upon determination of auth dispute, such Sublease Profits shall be recalculated and any overpayment shall be returned, or underpayment promptly made, on demand plus interest on such overpayment or underpayment at the rate of two percent (2%) per annum over the Prime Rate. Tenant agrees to grant Landlord reasonable access to Tenant’s office for the purpose of verifying Sublease Profits and to make copies of any and all bills, vouchers and other documents relating thereto, subject to reimbursement by Landlord for the cost of such copies. In the event that a review of Tenant’s books and records pursuant to this Paragraph reveals that Tenant has understated Sublease Profits by in excess of five percent (5%) of the actual Sublease Profits payable to Landlord, Tenant shall also reimburse Landlord for the reasonable expenses incurred by Landlord in conducting such review of Tenant’s books and records and the accounting firm costs. If a part of the consideration for any subletting shall be payable other than in cash, the payment to Landlord shall be payable in cash based on the cash value of the other non cash considerations. Tenant shall pay Landlord its share of the Sublease Profits promptly upon Tenant’s receipt from time to time of periodic payments from a subtenant or at such other time as Tenant shall realize the Sublease Profits from such sublease. Landlord shall not be responsible for any deficiency in amounts received for a sublease in relation to the Rent due hereunder.

E. In case Tenant proposes to Landlord an assignment of 100% of its interest in this Lease by the notice described in Paragraph 16.A hereof, Landlord shall have the option to terminate this Lease, If Landlord wishes to exercise its option to terminate, Landlord shall, within fifteen (15) days after Landlord’s receipt of the notice from Tenant described in Paragraph 16.A., send to Tenant a notice of termination. The date on which such termination will be effective shall be the proposed commencement date of the assignment. Tenant shall automatically be released from all obligations under this Lease to be performed after the effective date of such termination. Landlord shall have no option to terminate this Lease for assignments or sublets pursuant to Paragraph 16.B hereof.

If Landlord approves such assignment but does not so terminate this Lease, Tenant may proceed with the proposed assignment. Landlord and Tenant shall share in the ratio of 50% to 50% the profits from said assignment calculated and verified in the same fashion as described in Paragraph 16.D. above.

17. SURRENDER OF POSSESSION. On the last day of the Term, or upon any earlier termination of this Lease, or upon any re-entry by Landlord upon the Premises, Tenant shall quit and surrender the Premises to Landlord. Tenant shall remove all of Tenant’s trade fixtures, furniture and other personal property therefrom, shall restore the Premises wherever such removal results in damage thereto and shall otherwise generally leave the Premises in a reasonably tenantable condition. Any interest of Tenant in the alterations, improvements and additions to the Premises shall, without compensation to Tenant, become Landlord’s property at the termination of this lease by lapse of time or otherwise and such alterations, improvements and additions shall be relinquished to Landlord. Tenant shall remove alterations, additions and improvements and make such restorations to the Premises as are required pursuant to Paragraph 9.B herein.

If Tenant shall fail or refuse to remove any of Tenant’s property from the Premises, Tenant shall be conclusively presumed to have abandoned the same, and title thereto shall thereupon pass to Landlord without any cost either by setoff, credit, allowance or otherwise.

18. HOLDING OVER. Tenant shall pay to Landlord Rent at an annual rate equal to the greater of (1) Current Market Rate for the Premises, determined, if necessary, in accordance with Paragraph 30.G. hereof, or (ii) one hundred fifty percent (150%) of then current Base Rent for the Premises, plus one hundred fifty percent (150%) of the Additional Rent paid by Tenant during the previous Calendar Year herein provided, payable in monthly installments on the first day of each month or portion thereof for which Tenant shall retain possession of the Premises or any part thereof after the expiration or termination of the Term or of Tenant’s right of possession, whether by lapse of time or otherwise. Tenant shall also pay all damages sustained by Landlord by reason of such retention if such retention shall continue for thirty (30) or more days.

19. ESTOPPEL CERTIFICATE. Landlord and Tenant each agree, from time to time upon not less than tea (10) days’ prior request by the other party, to execute, acknowledge and deliver to the other party a statement in writing certifying (i) that this Lease is unmodified and in full force and effect (or if there have been modifications, a description of such modifications and that the Lease as modified is in full force and effect); (ii) whether the Term has commenced and the dates to which Rent and other charges have been paid; (iii) that the other party is not in default under any provision of this Lease, to the knowledge of the party furnishing the certificate, or i in default, the nature thereof in detail (and in case of certificates requested of Tenant, that, to the best knowledge of Tenant, Tenant has no existing defenses, set-offs, or claims hereunder, or, if any, specifying same); and (iv) such further matters as reasonably may be requested, it being intended that any such statement may be relied upon by any prospective assignee or sublessee of any tenant (including Tenant) of the Building, any mortgagees or prospective mortgagees thereof, any lender to Tenant, or any prospective and/or subsequent purchaser or transferee of all or part of Landlord’s interest in the Land and/or Building or of Tenant’s interest in the Premises.

20. SUBORDINATION. This Lease shall be prior to any mortgage or ground or underlying lease; provided, however, Tenant agrees to subordinate its rights hereunder at all times to (i) the lien of any mortgage or mortgages designated by Landlord and to all advances made or thereafter made upon the security thereof, and (ii) to all future ground leases or underlying leases of the Land and the Building designated by Landlord and to execute any such reasonable agreements evidencing such subordination as may be reasonably required by the mortgagee, trustee or ground or underlying lessor, as the case may be, and to attorn to and to recognize, as Landlord, the purchaser at a foreclosure sale or the mortgagee, trustee or its nominee in the event the mortgagee, trustee or such nominee accepts a deed in lieu of foreclosure, or the ground or underlying lessor in the event of the termination of such underlying or ground lease in return for and upon delivery to Tenant by such mortgagee, trustee or ground or underlying lessor, as the case may be (each being referred to as a “Lender”), of an agreement in a form reasonably satisfactory to Lender and Tenant providing that in the event of a foreclosure of

such mortgage or the giving of a deed in lieu of foreclosure or termination of such ground or underlying lease, this Lease shall not be terminated and Tenant may remain in possession of the Premises pursuant to the terms of this Lease and retain all of the rights, options and privileges granted to it hereunder as long as Tenant continues to perform its obligations hereunder and further providing that the purchaser at a foreclosure sale or transferee in the case of a deed in lieu of foreclosure or ground or underlying lessor, as the case may be, will assume all of the obligations of Landlord in such case; provided, however, that the holder of any mortgage, or purchaser at any foreclosure sale, as the case may be, shall not be bound by any prepayment of Base Rent or Additional Rent which Tenant may have paid in excess of the amounts then due for the current month (the “SNDA”). Tenant agrees to enter into an SNDA with any future Lender whose terms are no less favorable to Lender than those contained in the SNDA entered into between Tenant and Citicorp Real Estate, Inc. concurrently herewith.

Tenant also agrees to give any holder of any first mortgage, by registered or certified mail, a copy of any notice or claim of default served upon the Landlord by Tenant, provided that prior to such notice Tenant has been notified in writing (by way of service on Tenant of a copy of an assignment of Landlord’s interests in leases, or otherwise) of the address of such first mortgage holder.

21. CERTAIN RIGHTS RESERVED BY LANDLORD.

A. Landlord shall have the following rights without liability to Tenant for damage or injury to property, person or business on account of the exercise thereof, and the exercise of any such rights shall not be deemed to constitute an eviction or disturbance of Tenant’s use or possession of the Premises and shall not give rise to any claim for set off or abatement of rent or any other claims:

(1) To install, affix and maintain any and all signs on the exterior and on the interior of the Building; except that there shall be no signs for retail or commercial tenants in the lobby of the office portion of the Building and, other than for a tenant then having 400,000 RSF or more under lease (“Large Tenant”), there shall be no sign on the exterior of the Building indicating the occupancy of any tenant in the Building without the approval of Tenant which it may reasonably withhold. If there shall be a sign proposed for a Large Tenant, Tenant shall have the right to approve: (i) the installation of the sign and (ii) the text, location, size and style of such sign, such approvals not to be unreasonably withheld or delayed, and Tenant shall also have the right to equivalent signage. All Tenant’s tights to approve under this subparagraph shall exist only so long as Tenant (including any Affiliate or Successor Entity) is not in default hereunder (beyond any applicable cure period) and occupies at least 400,000 RSF in the Building. Landlord hereby approves all Tenant signage existing as of the date hereof. Landlord shall have the right to approve (which approval not to be unreasonably withheld) all additional lobby or exterior signage proposed by Tenant and not existing as of the date hereof.

work, to temporarily close doors, entryways, public space and corridors in the Building and to interrupt or temporarily suspend services or use of facilities, all without affecting any of Tenant’s obligations hereunder, so long as the Premises are accessible and usable and provided that Landlord shall use due diligence with respect thereto. Unless such repairs, renewals or improvements can be made during business hours without material interference with Tenant’s business operations and, except in the case of an emergency, Landlord shall make such repairs, alterations, or replacements during non-business hours;

(3) To furnish door keys or magnetic cards for the entry door(s) in the Premises at the commencement of the Lease and to retain at all times, and to use in appropriate instances, keys or magnetic cards to all doors within and into the Premises; provided that such system will permit the Landlord upon request of Tenant to cancel the effectiveness of the card held by any shareholder or employee or invitee of Tenant upon such person’s departure from Tenant or for any other reason. Tenant agrees to purchase only from Landlord additional duplicate keys or magnetic cards as required (at Landlord’s actual cost for such keys or magnetic cards), to change no locks or magnetic card readers, and not to affix locks or magnetic card readers on doors without the prior written consent of the Landlord not to be unreasonably withheld; provided that Landlord shall respond to Tenant’s request for such consent with reasonable promptness.

(4) To designate a building standard window covering for exclusive use throughout the Building;

(5) To approve the weight, size and location of safes, vaults, library shelving, file storage e and other heavy equipment and articles in and about the Premises and the Building so as not to exceed the legal live load per square foot designated by the structural engineers for the Building, and to require all such items and furniture and similar items to be moved into or out of the Building and Premises only at such times and in such manner as Landlord shall reasonably direct in writing. Tenant shall not install or operate machinery or any mechanical devices of a nature not directly related to Tenant’s ordinary use of the Premises without the prior written consent of Landlord, not to be unreasonably withheld;

(7) To reasonably regulate delivery and service of supplies and the usage of the loading docks, receiving areas and freight elevators;

(8) To show the Premises to prospective tenants within the final twelve (12) months of the Term (as the same may be extended), at reasonable times, and in a manner not to interfere with Tenant’s use and enjoyment of the Premises and, if vacated or abandoned, to show the Premises at any time and to prepare the Premises for reoccupancy;

(9) To erect, use and maintain pipes, ducts, wiring and conduits, and appurtenances thereto, in and through the Premises at reasonable locations that do not unreasonably interfere with Tenant’s business;

(10) To enter the Premises at any reasonable time upon reasonable prior notice (except no notice shall be required in the case of emergency) to inspect the Premises;

(11) Only Landlord or one or more persons approved by Landlord will be permitted to furnish bootblacking and barbering. Landlord may fix the hours during which, and the regulations under which, such supplies and services are to be furnished. Landlord expressly reserves the right to act as, or to designate, at any time and from time to time, an exclusive supplier of all or any one or more of said supplies and services, provided all such supplies and services shall be furnished on a basis which is reasonably competitive to that which would otherwise be directly available to Tenant; and Landlord furthermore expressly reserves the right to exclude from the Building any person attempting to furnish any of said supplies or services but not so designated by Landlord. Notwithstanding the foregoing, Tenant shall have the right to specify the vendors for other supplies and services for the Premises, subject to Landlord’s approval, which approval shall not be unreasonably withheld or delayed;

(12) To close the Building after hours and on any day which is not a business day, subject, however, to Tenant’s right to admittance to the Premises at any time under such reasonable regulations as Landlord may prescribe from time to time, which may include but shall not be limited to, a requirement that persons entering or leaving the Building identify themselves to a watchman by registration or otherwise and establish their right to enter or leave the Building.

Tenant shall comply with all such ivies and regulations, provided such ivies and regulations are uniformly enforced against all Building tenants and except to the extent that such rules and regulations unreasonably contradict or abrogate any right or privilege herein expressly granted to Tenant. Landlord will provide Tenant with a written copy of any modifications to the Rules and Regulations.

23. REMEDIES. If default shall be made in the payment of the Rent or any installment thereof or in the payment of any other sum required to be paid by Tenant under this Lease and such default shall continue for ten (10) days after written notice to Tenant; or if default shall be made in the observance or performance of any of the other covenants or conditions in this Lease which Tenant is required to observe and perform and such default shall continue for thirty (30) days after written notice to Tenant, unless with respect to any non

monetary default which cannot be cured within thirty (30) days, Tenant, in good faith, promptly after receipt of such notice, shall have commenced and thereafter shall continue diligently to reasonably prosecute and complete all action necessary to cure such default within an additional forty-five (45) days; or if a default which involves a hazardous condition is not cured by Tenant as promptly as reasonably possible upon written notice to Tenant; or if any involuntary petition in bankruptcy shall be filed against Tenant under any federal or state bankruptcy or insolvency act and shall not have been dismissed within ninety (90) days from the filing thereof, or if a receiver shall not have been dismissed within ninety (90) days from the date of his appointment, or if Tenant shall make an assignment for the benefit of creditors, or if Tenant shall admit in writing Tenant’s inability to meet Tenant’s debts as they mature, 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 after the date of filing, bankruptcy, reorganization, insolvency or liquidation proceedings, or other proceedings for relief under any bankruptcy law are instituted by or against Tenant and not dismissed within ninety (90) days after institution, then Landlord may treat the occurrence of any one or more of the foregoing events as a breach of this Lease, and thereupon at its option may, with or without any additional notice or demand of any kind to Tenant or any other person, have any one or more of the following described remedies in addition to all other rights and remedies provided at law or in equity or elsewhere herein:

(1) Landlord may terminate this Lease and the Term created hereby, in which event Landlord may forthwith repossess the Premises and be entitled to recover forthwith, as damages a sum of money equal to all sums due and owing Landlord hereunder to said date, all reasonable costs and expenses incurred by Landlord as a result of Tenant’s default, including reasonable attorneys’ fees, the excess of the then present value of the Rent provided to be paid by Tenant for the balance of the Term over the fair market rental value (discounted to present value) of the Premises, after deduction of all anticipated expenses or reletting, for such period, and the unamortized portion of the Allowance given Tenant hereunder (assuming an amortization of such amount over the shortest period allowable under the Internal Revenue Code for the type of Improvements installed in the Premises). In computing present value, a discount rate equal to the rate of interest on the most recently issued 10 Year U.S. Treasury bonds shall be used. Should the fair market rental value of the Premises, after deduction of a reasonable estimate expenses of reletting, for the balance of the Term exceed the present value of the Rent provided to be paid by Tenant for the balance of the Term, Landlord shall have no obligation to pay to Tenant the excess of any part thereof; and

(2) Landlord may terminate Tenant’s right of possession and may repossess the Premises by forcible entry and detainer suit, by taking peaceful possession or otherwise, without terminating this Lease or Tenant’s obligation to pay Rent hereunder, in which event Landlord shall attempt to relet the same for the account of Tenant, for such rent and upon such terms as shall be reasonably satisfactory to Landlord. For the purpose of such reletting, Landlord is authorized to decorate, repair, remodel or alter the Premises If Landlord shall fall to relet the Premises, Tenant shall pay to Landlord as damages a sum equal to the amount of the Rent reserved in this Lease for the balance of the Term, as and when payable pursuant to this Lease. If the Premises are relet and a sufficient sum shall not be realized from such reletting after paying all of the reasonable

costs and expenses of all decoration, repairs, remodeling, alterations and additions and the expenses of such reletting and of the collection of the rent accruing therefrom to satisfy the Rent provided for in this Lease, Tenant shall satisfy and pay the same upon demand therefor from time to time. Tenant shall not be entitled to any rents received by Landlord in excess of the Rent provided for in this Lease. Tenant agrees that Landlord may file suit to recover any sums falling due under the terms of this Paragraph 23 from time to time and that no suit for or recovery of any portion due Landlord hereunder shall be any defense to any subsequent action brought for any amount not theretofore reduced to judgment in favor of Landlord or otherwise recovered by Landlord.

In the event Landlord defaults in the performance of any of its obligations to Tenant hereunder, or breaches any representation, express or implied, to Tenant in connection with this Lease, and such default or breach continues for a period of thirty (30) days following written notice thereof from Tenant to Landlord unless with respect to a default or breach which cannot be cured within thirty (30) days, Landlord, in good faith, promptly after receipt of such notice, shall have commenced and thereafter shall continue diligently to reasonably prosecute and complete all action necessary to cure such default within an additional forty-five (45) days, then Tenant may (i) take such action as is reasonably necessary to cure Landlord’s default, (ii) bring suit against Landlord for damages, and/or c bring suit to specifically enforce Landlord’s obligations under this Lease. In the event Tenant cures such default by Landlord as provided In item (1), Landlord will reimburse Tenant for all reasonable costs and expenses incurred by Tenant in curing Landlord’s default within ten (10) days after notice from Tenant given from time to time as costs are incurred. Notwithstanding the foregoing, in cases of emergency, Tenant may cure Landlord’s obligations if Landlord fails to commence the cure thereof as soon as reasonably possible following Tenant’s notice to Landlord.

24. EXPENSES OF ENFORCEMENT.

A. Tenant shall pay upon demand all Landlord’s reasonable costs, charges and expenses, including the reasonable fees and cut-of-pocket expenses of counsel, agents and others retained by Landlord incurred in successfully enforcing Tenant’s obligations hereunder or incurred by Landlord in any litigation, negotiation or transaction in which Tenant causes Landlord without Landlord’s fault to become involved or concerned.

B. Landlord shall pay upon demand all Tenant’s reasonable costs, charges and expenses, including the reasonable fees and out-of-pocket expenses of counsel, agents and others retained by Tenant incurred in successfully enforcing Landlord’s obligations hereunder or incurred by Tenant in any litigation, negotiation or transaction in which Landlord causes Tenant without Tenant’s fault to become involved or concerned.

25. COVENANT OF OUIET ENJOYMENT. Landlord covenants that Tenant, on paying the Rent, charges for services 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 hereof and Landlord shall defend, at Landlord’s sole cost and expense, Tenant’s right of quiet enjoyment.

To each party’s knowledge, except for the aforementioned brokers, no other broker initiated or participated in the negotiation of this Lease, submitted or showed the Premises to Tenant or is entitled to any commission in connection with this Lease, and each agrees to indemnify, defend and hold the other harmless from all claims from any other real estate broker for commission or fees in connection with this Lease claiming through such representing party.

Landlord and Tenant acknowledge and agree that Tenant shall not be responsible for any increases to the foregoing City of Chicago tax/fee or any new parking taxes or fees, but said $30.00 per month tax/fee shall be reduced by the amount of any reduction, if any, to the foregoing tax/fee levied by the City of Chicago. Such spaces shall be for the exclusive use by Tenant and shall be in locations designated by Tenant, such rights to extend through the term of this Lease and any extensions thereof, and to include the right to sublease such spaces. In addition, Tenant shall be entitled, at regular annual Building rates therefor, to any parking spaces which were rented by the immediately preceding tenants in space added to the Premises after the Commencement Date. Tenant may release such parking spaces, or any thereof, so leased at any time(s) on not less than thirty (30) days’ notice and shall not have any rights for the number of spaces so released at any time thereafter, Tenant may request additional parking spaces over and above the 75 space allocation which, subject to availability, shall be provided at the monthly rate then prevailing in similar parking structures in downtown Chicago. Landlord shall provide reduced parking rates for bikes and motorcycles consistent with rates for bikes and motorcycles charged by similar parking structures in downtown Chicago. Landlord shall continue to provide the amount, type and quality of parking services which Landlord provides as of the date hereof, including, but not limited to, car washes. If in the future Landlord provides reserved parking spaces to other tenants In the Building, landlord shall also provide Tenant with the same right to have reserved parking as provided to such other tenant.

Landlord acknowledges that Tenant has a storage and workshop space on level P-2 of the Building’s parking garage (the “Storage and Workshop Space”), which the parties acknowledge and agree contains approxim2tely 1,500 RSP and occupies six (6) parking spaces. With respect to the Storage and Workshop Space, on or before the Commencement Date, Tenant shall, in Tenant’s sole discretion, either (i) vacate the Storage and Workshop Space and remove all of Tenant’s belongings from the Storage and Workshop Space, (ii) elect to have the six (6) spaces of the Storage and Workshop Space included as part of the aforementioned 75 parking spaces allocated to Tenant or (iii) elect to lease the six (6) spaces of the Storage and Workshop Space for the Term and to pay for such six (6) spaces at the monthly rate for parking spaces charged by Landlord for spaces in the Building parking garage other than Tenant’s 75 spaces.

B. Communication System. Tenant shall have the right to maintain any satellite, microwave, or other communication systems, if any, belonging to Tenant and installed upon the Building’s roof as of the Commencement Date hereof. In addition, Tenant shall have the right at any time during the Term (or any extension thereof) to lease from Landlord up to ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ feet of additional space on the roof of the Building at no cost to Tenant for a satellite, microwave or other communications system, so long as such system does not impair the use by other tenants of their space in the Building or other satellite, microwave or other

communication systems then installed, or in Landlord’s reasonable judgment, compromise the aesthetics of the Building. Once Tenant installs any of the foregoing systems, Landlord shall not enter into any new agreements with any other tenants for the installation of a satellite, microwave or other communications system which impairs the use by Tenant of: (1) its space in the Building, or (II) any satellite, microwave or other communication systems then installed by Tenant. Tenant shall submit plans for such system and the names of the contractors who will be installing such system, all of which shall be subject to Landlord’s reasonable approval. Tenant shall pay all costs related to the installation, operation and maintenance of such system, including without limitation, the cost of any structural modifications to the Building made by Landlord and necessary, in the opinion of Landlord’s structural engineer, to accommodate the system. Tenant shall, at Landlord’s option, remove any system(s) at the expiration of the Term, unless the Term is extended, in which case Tenant shall, at Landlord’s option, remove the system(s) at the expiration of the Term as extended. In each case, Tenant shall restore the Building to the condition existing prior to the installation of any such system(s). Tenant shall secure all zoning and regulatory approvals necessary for the system, at its expense.

C. Right of First Refusal for Roof Space. In addition to the above rights to rent space on the roof, Landlord hereby grants Tenant a right of first refusal for any proposed leasing of space on the roof of the Building to any other party. At such time as Landlord desires to enter into a lease of any part or portion of the space on the roof of the Building with a bonafide tenant, Landlord shall give Tenant written notice of the terms and conditions of the proposed lease. Tenant shall have ten (10) business days from the receipt of such notice to notify Landlord in writing that Tenant elects to lease said space on the same terms and condition as contained in Landlord’s notice, and in such case, Landlord and Tenant shall then enter into a lease of said space. If Tenant exercises this right, Tenant shall in fact use said roof apace for satellite, microwave or communications purposes. In the event Tenant does not exercise such election within said ten (1.0) day period, then Tenant shall be deemed to have waived this right of first refusal for the proposed lease, but such waiver shall be only for the lease proposed in Landlord’s notice and not for any subsequent proposed lease of space on the roof. If the proposed lease does not become effective within ninety (90) days after Landlord’s notice, then Tenant shall again have this right of first refusal with respect to that proposed lease.

In no event shall Landlord allow any roof space to be used in a manner that unreasonably interferes with Tenant’s satellite, microwave or other communications system on the roof.

D. Landlord’s Alterations After Construction. Other than as is specifically allowed under the paragraphs of this Lease, so long as Tenant (including any Affiliate or Successor Entity) occupies at least 400,000 RSF of the Building and is not in default hereunder (beyond any applicable cure period), then the Landlord shall not, without in each case obtaining the prior written consent of Tenant, construct, install or make any major alteration to, or change in, the exterior or facade of the Building, elevator lobby design or signage, elevator cab upgrades, bathroom upgrades or corework, unless such major alterations or changes are approved by Tenant, such approval not to be unreasonably withheld or delayed.

30. TENANT’S EXPANSION.

A. Tenant shall have and is hereby granted the options to add the Expansion Space (hereinafter described in the following table), for the remaining Term of this Lease and any extensions thereof upon the same terms, covenants and conditions contained in this Lease, except for the payment of Base Rent (which shall be payable in the amounts described below)

and except as otherwise specifically provided in this Paragraph 30. Tenant’s obligation to pay Tenant’s Expense Participation Amount, Base Rent and any other Rent or Additional Rent for any particular Expansion Space shall commence on the date such space is actually made available to Tenant to be added to the Premises. In the event that Tenant exercises its expansion option(s) pursuant to this Paragraph 30, the Expansion Space thereby added to the Premises shall become a part of the Premises for all purposes of this Lease, and any reference to the term “Premises” shall be deemed to refer to and include any such Expansion Space, except as otherwise expressly provided otherwise in this Lease.

(i) Space Called	(ii) Floor	(iii) Period, based on anniversaries of Commencement Date within which Space becomes part of the Premises	(iv) Base Rent When such Space Becomes Part of the Premises
“First Expansion Space”	32^nd floor 25,000 square feet	Six months before to Six months after 5^th [2002] anniversary	95% of “Market Rate”

(i) Space Called	(ii) Floor	(iii) Period, based on anniversaries of Commencement Date within which Space becomes part of the Premises	(iv) Base Rent When such Space Becomes Part of the Premises
“Second Expansion Space”	38^th floor 25,000 square feet	Six months before to Six months after 5^th [2007] anniversary	95% of “Market Rate”

B. Tenant’s options to expand shall be exercised as follows: On each occasion, Landlord shall give Tenant notice of each particular Expansion Space, the dates on which such spaces will be tendered to Tenant (the “Specification Notice”), and the rent for such Expansion Space, not less than fifteen (15) months prior to the earliest date stated in the Specification Notice for delivery of any such Expansion Space (the “Availability Date”). Tenant shall deliver a non-binding written notice to Landlord of its intent to exercise its option to expand not less than thirteen (13) months prior to the Availability Date of the Expansion Space (the “Option Notice”). If Tenant does not agree to the rent specified in the Specification Notice, Tenant shall state in its Option Notice that is desires the Market Rate to be calculated pursuant to Paragraph 30.G. Thereafter, the Market Rate for the particular Expansion Space will be so

calculated. Such calculation shall reflect the Market Rate that would be payable per annum for a term commencing on the first day of the term for the particular Expansion Space with respect to which the calculation is being made, provided that such calculations shall be final and shall not be recalculated at the actual commencement of such Expansion Space term (if any). If Tenant fails to give its non-binding written notice of its intent to exercise its option to expand when due as hereinabove provided, Tenant will be deemed to have waived such option to expand.

If Tenant exercises its expansion option, Landlord shall deliver possession of each particular Expansion Space to Tenant within a period extending six (6) months prior to, until six (6) months after, the Availability Date contained in the Specification Notice (the “Delivery Window”). Landlord shall use reasonable efforts to deliver the Expansion Space to Tenant within the Delivery Window and Landlord shall take all commercially reasonable actions to remove holdover tenants from the Expansion Space. Landlord acknowledges that remedies at law will not be adequate for the damages Tenant will incur for a failure by Landlord to deliver the Expansion Space within the Delivery Window. Therefore, if Landlord fails to deliver the Expansion Space within the Delivery Window, Tenant may pursue an action for specific performance. In addition, Landlord shall have the right, by notice to Tenant from time to time at least six (6) months prior to the then current Availability Date for any floor of any Expansion Space, to change the location of such floor, provided that If the floor or floors being replaced were to be contiguous to the Premises when added to the Premises, the replacement floor or floors so designated must also be contiguous to the Premises when added to the Premises. Tenant’s right to add floors pursuant to these subparagraphs 30.A. and 30.B. shall be exercised in full floor increments.

C. Each Expansion Space (or part thereof) shall become part of the Premises and, except as provided in Paragraph 30.8., Tenant’s rental obligation for such Expansion Space (or part thereof) shall commence upon its delivery to Tenant in accordance with Paragraphs 30.A. and 30.B.

D. Notwithstanding anything to the contrary contained herein, (i) if Tenant exercises its first Contraction Option set forth in Paragraph 31 (i.e. year 2000), Landlord may designate the Contraction Space set forth in the 2000 Contraction Option as the First Optional Expansion Space; and (ii) if Tenant exercises its second Contraction Option set forth in Paragraph 31 (i.e. year 2005), Landlord may designate the Contraction Space set forth in such 2005 Contraction Option as the Second Optional Expansion Space. Landlord shall not lease space of less than 3,000 RSF on any floor which is subject to any of Tenant’s expansion options without the prior written consent of Tenant, which consent may be withheld in Tenant’s sole discretion.

E. Tenant’s notice of exercise of an option for Optional Expansion Space or notice of exercise of any other rights or options granted pursuant to Paragraphs 31, 32, 34 and 35 of this Lease shall be effective only if at the time of service of such notice of exercise the following conditions (the “Expansion Conditions”) shall be satisfied:

(1) Landlord shall not have notified Tenant that Tenant is in default in the performance of any of the monetary or material non-monetary terms, covenants, and conditions contained in this Lease which default has not been cured;

(2) This Lease shall not have been terminated and shall be in full force and effect; and

(3) There shall not have been any assignment of Tenant’s interest in this Lease except as provided in Paragraph 30.H.

F. The Base Rent for the First Expansion Space and Second Expansion Space (as the case may be) shall be at a rate equal to 95% of the Market Rate (defined hereinafter) for such space. For purposes of this Paragraph 30, “Rate shall mean the fair net rental per annum (which shall be net of all Taxes and Operating Expenses) for a lease (but not a sublease) by a new tenant for “comparable space” (hereinafter defined) for a period commencing when the fair net rental being determined would first be payable, assuming no rent abatements of any kind per rentable square foot, for a term equal to the number of years remaining in the Term (including any Extension Term, with respect to winch Tenant has delivered its final binding written notice pursuant to Paragraph 34). The calculation of Market Rate shall be calculated on a net present value basis and shall take into account (and the fair net rental shall be decreased by the present value of any then market brokers’ commission and of any then market tenant improvement, free rent other concession which would be available to a new tenant, and shall also take into account (and the fair net rental shall be increased by) the present value of the cost of any actual brokers’ commission or actual tenant improvement, free rent or other concession, if any, agreed by the Landlord and Tenant to be payable or to be granted to Tenant in connection with the particular expansion option with respect to which Tenant has given its non binding notice. The calculation of Market Rate shall also be based on the assumption that there will be no financial escalation of Rent or stepping of Rent or similar increases over time other than the 2.5% annual increase to Base Rent provided for in Paragraph 4. The calculation of Market Rate shall also take into account that Tenant pays Tenant’s Proportionate Share of the Operating Costs and Taxes in each fiscal year. As used herein, the term “comparable space” means similar space in office buildings in the central business district of Chicago where the Building is located, which are comparable to the Building in reputation, quality, age, size, location, and level and quality of services provided, and which have similar occupancy of the Building, but excluding those leases where tenants have an equity interest in the building.

G. For purposes of Paragraphs 30 and 34 of this Lease ‘Market Rate” shall be determined as follows:

(1) (1) On or before five (5) days after the time at which Tenant must provide the Landlord with its non-binding written notice under this Lease of its intent to exercise any of its rights to: (i) expand the Premises under this Paragraph 30 or, (ii) extend the Term of this Lease under ▇▇▇▇▇▇▇▇▇ ▇▇, ▇▇▇▇▇▇▇▇ and Tenant shall commence negotiations to agree upon the Market Rate (to be multiplied by the RSF in the Premises) applicable thereto. If the Landlord and Tenant are unable to reach agreement on the Market Rate within twenty-one (21) days after the date negotiations commenced, then the Market Rate shall be determined in accordance with Paragraph 30.G.(2) below.

(2) If the Landlord and Tenant are unable to reach agreement on the Market Rate within said twenty-one (21) day period, then within seven (7) days, the Landlord and Tenant shall each simultaneously submit to each other in a sealed envelope its good

faith estimate of the Market Rate (each, a ‘Good Faith Estimate’). If the higher of such estimates is not more than one hundred five percent (105%) of the lower of such estimates then the Market l shall be the average of the two estimates and shall be final and binding on Landlord and Tenant and Tenant’s Option Notice shall become binding upon Tenant. Otherwise, within five (5) days after the expiration of such seven (7) day period Tenant may submit the question to arbitration in accordance with Paragraph 30.G.(3) below.

(3) If the Landlord and Tenant are unable to agree upon the Market Rate by exchange of Good Faith Estimates, then Tenant may, by written notice to Landlord within five (5) days after the exchange of Good Faith Estimates pursuant to Paragraph 30.G.(2) above, request to resolve the dispute by arbitration, whereupon Tenant’s Option Notice shall become binding upon Tenant. If Tenant does not provide such notice within the aforementioned five (5) days, Tenant will be deemed to have waived its option to expand under this Paragraph 30 or its option to extend the Term of this Lease under Paragraph 34, as applicable. Within seven (7) days after the receipt of such request, the parties shall select, as an arbitrator, a mutually acceptable independent MAI appraiser with experience in real estate activities, including at least five (5) years experience in appraising office space in the central business district of the City of Chicago (a “Qualified Appraiser”). If the parties cannot agree on a Qualified Appraiser, then within a second period of seven (7) days, each shall elect a Qualified Appraiser and within ten (10) days thereafter the two appointed Qualified Appraisers shall select a third Qualified Appraiser and the third Qualified Appraiser shall be the arbitrator and shall determine the Market Rate. If one party shall fail to make such appointment within said second seven (7) day period, then the Qualified Appraiser chosen by the other party shall be the sole arbitrator.

(4) Once the arbitrator has been selected as provided in Paragraph 30.G.(3) above, then, as soon thereafter as practicable but in any case within twenty-one (21) days, the arbitrator shall select one of the two Good Faith Estimates of Market Rate previously submitted by the Landlord and Tenant in accordance with 30.G.(2) above, which shall be the one that is closer to the fair market net rental value as determined by the arbitrator. The value so selected shall be the Market 1 The decision of the arbitrator as to the Market Rate shall be submitted in writing to, and be final and binding on, the Landlord and Tenant. If the arbitrator believes that expert advice would materially assist him, he may retain one or more qualified persons, including but not limited to, legal counsel, brokers, architects or engineers, to provide such expert advice. The party whose estimate is not chosen by the arbitrator shall pay the costs of the arbitrator and of any experts retained by the arbitrator. Any fees of any counsel or expert engaged directly by the Landlord or Tenant, however, shall be borne by the party obtaining such counsel or expert.

H. The provisions of this Paragraph 30 and Paragraphs 31, 32 and 34, and 35 shall apply only to Tenant, and shall not inure to the benefit of any assignee of Tenant other than (i) any party resulting from a merger or consolidation with Tenant so long as Tenant or an Affiliate is the dominant and controlling party after such merger, (ii) any party succeeding to the business and assets of Tenant, or (iii) any Affiliate of Tenant.

I. Any space added to the Premises pursuant to this Paragraph 30 shall be delivered by Landlord to Tenant in broom clean condition, but otherwise as is, and Landlord shall have no obligation to contribute to the cost of any construction or remodeling by Tenant.

J. Promptly after Tenant’s exercise of any expansion option, Landlord shall prepare an amendment to the Lease, in a form reasonably satisfactory to Landlord and Tenant, to reflect the increase to the size of the Premises and Tenant’s Proportionate Share and any other appropriate terms, due to the exercise of such expansion option. Tenant shall execute and return such an amendment to the Lease within fifteen (15) days after its submission to Tenant.

31. CONTRACTION OPTION. Tenant shall, provided that all the Expansion Conditions are then satisfied, have the option (the “Contraction Option”) to exclude from the Premises an area of one full floor of Premises designated by Tenant as hereinafter provided, which contraction will be effective as of February 28, 2000, 2005, and 2010 (the “Contraction Date”). Space designated by Tenant to be excluded from the Premises (the “Contraction Space”) must be at a non-contiguous floor or the upper [or lower] end of the largest contiguous 2 block pace then leased by Tenant. The Contraction Option shall be exercised, of the essence, by notice given by tenant to Landlord, on or before twelve (12) months prior to any such Contraction Date identifying the Contraction Space (the “Contraction Notice”). Each time Tenant fails to timely deliver its Contraction Notice, Tenant will be deemed to have waived such Contraction Option for the applicable Lease year. If Tenant timely delivers its Contraction Notice, then as of the relevant Contraction Date: (1) Tenant shall vacate the Contraction Space and surrender possession thereof to Landlord in accordance with the requirements of this Lease; (ii) the Rentable Area of the Premises shall be reduced by the Rentable Area of the Contraction Space so surrendered; and (iii) Tenant’s Proportionate Share shall be reduced by a percentage derived by dividing the Rentable Area of the Contraction Space surrendered by the I Area of the Office Portion of the Building. If Tenant fails to completely vacate the Contraction Space and surrender possession thereof to Landlord in accordance with Paragraph 17 of the Lease on or before the Contraction Date, such failure shall be treated as a holding over by Tenant, and Landlord shall be entitled to all of its remedies thereof pursuant to Paragraph 18 of this Lease. Notwithstanding any such vacation and surrender, Tenant shall remain liable for the payment to Landlord of’ all rent and other sums due or accrued, and for the performance and keeping of all the covenants, agreements and obligations under this Lease to be performed, paid and kept by Tenant with respect to the Contraction Space prior to the Contraction Date. Promptly after Tenant’s exercise of its Contraction Option, Landlord shall prepare an amendment to the Lease in a form reasonably satisfactory to Landlord and Tenant to reflect the reduction to the size of the Premises and Tenant’s Proportionate Share and any other appropriate terms, due to the return of the Contraction Space. Tenant shall execute and return such an amendment to the Lease within fifteen (15) days after its submission to Tenant.

32. RIGHT OP FIRST REFUSAL. Provided Tenant (including any Affiliate or Successor Entity) occupies at least 400,000 RSF in the Building and is not in default hereunder (beyond any applicable cure period), subject to Paragraph 32.B. below, and subject to any expansion, renewal, first offer, and first refusal options of any current tenant(s) in the Building (individually, the (“Prior Tenant”) during the Term of this Lease, Tenant shall, provided all Expansion Conditions are then satisfied, have and is hereby granted a right of first refusal on any space in the Building of 5,000 RSF or more, that is not originally demised to Tenant under this lease (collectively, the “Refusal Space”) which right shall be exercised in accordance with the procedures set forth in Paragraph 32.A. below.

A. If at any time during the Term of this Lease any Refusal Space becomes available for lease to anyone other than a Prior Tenant, Landlord shall give written notice thereof to Tenant (“Landlord’s Refusal Notice”). Landlord’s Refusal Notice must be given not less than six (6) months nor more than twelve (12) months in advance of such availability and shall contain a summary of the terms upon which landlord intends to offer the Refusal Space for lease to the market (the “Third Party Lease”). Landlord’s Refusal Notice shall specifically indicate the monthly payment stream (the “Monthly Payment”). The Monthly Payment is a level monthly payment over the term of the Third Party Lease which, when discounted at a monthly equivalent rate equal to a ten percent (10%) annual rate, for the term of the Third Party Lease, equals the same net present value as the economic terms (including, but not limited to, the net rental rate, free rent period, tenant improvement allowances and leasing commissions) of the Third Party Lease. Such Monthly Payment shall be the monthly rental rate for the Refusal Space. Tenant shall notify Landlord in writing within fifteen (15) days of receipt of Landlord’s Refusal Notice whether it desires to lease the Refusal Space on the terms set forth in Landlord’s Refusal Notice; and failure to notify Landlord within said fifteen (15) day period shall be deemed a refusal by Tenant. After any such refusal or deemed refusal, Tenant shall have no further tights to such Refusal Space and Landlord shall be free to lease such space to any person or entity for any term, subject to Tenant’s other options set forth in this Lease and subject to the following conditions:

(i) The net present value as of the proposed commencement date of the Third Party Lease expressed as a single dollar figure, discounted using a rate of ten percent (10%) per annum, of all rent (other than such tenant’s proportionate share of operating expenses and taxes) of whatever nature or however denomirl2ted for the term of the Third Party Lease less such net present value of all other proposed economic terms of the Third Party Lease shall not be less than ninety-five percent (95%) of the comparable amount determined by using the economic terms set forth in the Landlord’s Refusal Notice for the space in question;

(ii) The Third Party Lease must be executed within six (6) months after the date of the Landlord’s Refusal Notice; and

(iii) If a Third Party Lease does not meet the foregoing conditions, then Landlord shall not enter into the Third Party Lease until Landlord again complies with the provisions of this Paragraph 32 by delivering a new landlord’s Refusal Notice to Tenant and Tenant does not exercise its right of first refusal to lease such space on the terms and conditions set forth in the second Landlord’s Refusal Notice within the applicable time periods.

Upon the expiration of the Third Party Lease, Tenant shall again have a right of first refusal on the terms set forth in this Paragraph 32 with respect to the space covered thereby.

B. If Tenant exercises its right of first refusal with respect to such Refusal Space, such space shall be added to the Premises subject to the following:

(i) If Tenant exercises its right of first refusal for a Refusal Space within the first ten (10) Calendar Years of the Term of the Lease, such Refusal Space shall be added to the Premises for the remaining Term of the Lease (including any exercised Extension Term(s)) on (1) all of the terms, covenants and conditions specified in Landlord’s Refusal Notice (including, but not limited to, the Monthly Payment), and (ii) the terms, covenants and conditions of this Lease to the extent that such terms, covenants and conditions of this Lease do not conflict with landlord’s Refusal Notice;

(ii) If Tenant exercises its right of first refusal for a Refusal Space after the first ten (10) Calendar Years of the Term of the Lease, and such Refusal Space is less than 50,000 RSF, then such Refusal Space shall be added to the Premises for the remaining Term of the Lease (including any exercised Extension Term(s)) on (1) all of the terms, covenants and conditions specified in Landlord’s Refusal Notice (including, but not limited to, the Monthly Payment), and (ii) the terms, covenants and conditions of this Lease to the extent that such terms, covenants and conditions of this Lease do not conflict with landlord’s Refusal Notice;

(iii) If Tenant exercises its right of first refusal for a Refusal Space after the first ten (10) Calendar Years of the Term of the Lease, and such Refusal Space is greater than 50,000 RSF, then such Refusal Space shall be added to the Premises for the term indicated in the Landlord’s Refusal Notice, up to a maximum term of ten (10) years, on (i) all of the terms, covenants and conditions specified in Landlord’s Refusal Notice (including, but not limited to, the Monthly Payment), and (ii) the terms, covenants and conditions of this Lease to the extent that such terms, covenants and conditions of this Lease do not conflict with Landlord’s Refusal Notice.

provided, however, that notwithstanding anything contained herein to the contrary, during the Extension Terms, if any, rent and all other economic terms applicable to any Refusal Space shall be adjusted in the manner provided in Paragraph 34 hereof, and the rent and other economic terms described in Landlord’s Refusal Notice shall not apply in any Extension Term. Any Refusal Space added to the Premises pursuant to this Paragraph 32.B. shall become a part of the Premises for all purposes of this Lease, and any reference in this Lease to the term “Premises” shall be deemed to refer to and include such portion of the Refusal Space, except as expressly provided otherwise in this Lease.

C. Promptly after Tenant’s exercise of its right of first refusal pursuant to this Paragraph 32., Landlord shall prepare an amendment to the Lease, in a form reasonably satisfactory to Landlord and Tenant, to reflect changes in the size of the Premises, Base Rent, Tenant’s Proportionate Share and any other appropriate terms, due to the addition of the Refusal Space. Tenant shall execute and return such an amendment to the Lease within fifteen (15) days after its submission to Tenant.

33. LIMITATIONS ON LIABILITY: CONFIDENTIALITY.

It is expressly understood and agreed by Tenant that none of Landlord’s covenants, undertakings or agreements are made or intended as personal covenants, undertakings or agreements by• Landlord, or its beneficiaries, and any liability for damage or breach or nonperformance by Landlord shall be collectible only out of Landlord’s interest in the Building and Land, if any, and no personal liability is assumed by, nor at any time may be assailed against Landlord, its beneficiaries or any of their heirs, legal representatives, successors and assigns, all such liabilities, if any, being expressly waived and released by Tenant.

Landlord further agrees, subject to the terms and provisions below, and except as specifically set forth herein, to keep confidential any non-public financial information of Tenant or its shareholders disclosed to Landlord under the provisions of this Lease; provided, however, that nothing herein shall restrict or prohibit disclosure of any such information: (a) that was or becomes generally available to the public other than as a result of disclosure by Landlord; (b) that was or becomes available on a non-confidential basis from a source other than Tenant (provided that such source was not bound by a confidentiality agreement with Tenant known to Landlord after reasonable inquiries, if any, which a reasonable person under the circumstances would have made); (c) to the extent required by statute, rule, regulation, law, governmental authority or judicial process; (d) to any of the following: (:1) any entity which controls, is controlled by or is under common control with Landlord; (ii) any successor of Landlord; and/or (iii) any actual or potential purchaser, assignee or transferee of all or any portion of the Building; (e) in connection with Landlord’s administration of the Lease, to any of its examiners, accountants, attorneys, consultants, appraisers, auditors or agents, to the extent reasonably required; or (1) to any other person or entity to the extent reasonably required in connection with any litigation, or proceeding to enforce remedies under this Lease. Landlord shall require that those persons and entities to whom disclosure is made pursuant to Paragraph 33(d and e), agree to be bound by the provisions of this Paragraph 33 in the event disclosure is required to be made pursuant to Paragraph 33(c), Landlord shall give Tenant notice thereof as promptly as practicable under the circumstances and Tenant shall have the right to seek an appropriate protective order (the “Confidentiality Requirements”). The provisions of this Paragraph 33 shall supersede in their entirety all prior agreements and understandings concerning confidentiality or disclosure of information entered into by Landlord and Tenant (or a parent, subsidiary of a of either or both of the foregoing) with respect to the matters set forth herein.

34. TENANT’S OPTIONS TO EXTEND. Tenant shall, provided that all of the Expansion Conditions are then satisfied, have the right to extend the term of this Lease for four additional periods of five (5) years each (each such period is called an “Extension Term”). Each Extension Term shall be upon the same terms, covenants and conditions contained in this Lease, except the amount of the annual Ease Rent payable during any Extension Term, and any

reference in the Lease to the “Term” of the Lease shall be deemed to include any Extension Term and apply thereto, unless it is expressly provided otherwise. Tenant shall have no extension option beyond the aforesaid four consecutive five year extension options. Any termination of this Lease during the initial Term of this Lease shall terminate all rights under this Paragraph 34.

A. The Base Rent during an Extension Term for any space then constituting a portion of the Premises (including, without limitation, any Expansion Space) shall be at a rate equal to 95% of the “Market Rate”. For purposes of this Paragraph 34, “Market Rate” shall mean the fair net rental per annum (which shall be net of all Taxes and Operating Expenses) for a period commencing when the fair net rental being determined would first be payable, assuming no rent abatements of any kind, per rentable square foot for an existing tenant entering into any renewal lease for “comparable space” (hereinafter defined), for a term equal to the Extension Term, but excluding any renewal by an existing tenant at a rent agreed to at an earlier date pursuant to a tenant’s renewal option. The calculation of Market Rate shall be calculated on a net present value basis and shall take into account (and the fair net rental shall be increased by) the present value of the cost of any actual brokers’ commission or actual tenant improvement, free rent or other concession, if any, agreed by the Landlord and Tenant to be payable or to be granted to Tenant in connection with the particular extension option with respect to which Tenant has given its non-binding notice). The calculation of Market Rate shall also be based on the assumption that there will be no financial escalation of Rent or stepping of Rent or inii1 increases over time. The calculation of Market Rate shall also take into account that Tenant pays Tenant’s Proportionate Share of the Operating Costs and Taxes in each fiscal year. M used herein, the term “comparable space” means similar size space in office buildings in the central business district of Chicago where the Building is located, which are comparable to the Building in reputation, quality, age, size, location, and level and quality of services provided, and which have similar occupancy of the Building, but excluding those leases where tenants have an equity interest in the building.

B. Each option to extend shall be exercised by Tenant giving non-binding notice to Landlord not later than eighteen (18) months prior to the end of the initial Term (or 18 months prior to the end of the first, second, or third extensions thereof, as the case may be), to extend the Term of this Lease (the “Extension Notice”). Thereafter, the Market Rate for the particular Extension Term shall be calculated pursuant to Paragraph 30.G. Such calculation shall reflect the Market Rate that would be payable per annum for a term commencing on the first day of the particular Extension Term with respect to which the calculation is being made, provided that such recalculation shall be final and shall not be recalculated at the actual commencement of such Extension Term. If Tenant fails to timely give the Extension Notice, Tenant will be deemed to have waived such option to extend. If Tenant fails to exercise any particular option to extend set forth herein, then all subsequent options to extend the Term shall expire.

35. RIGHT OP FIRST OFF PURCHASE.

A. Right of First Offer. Subject to and upon the terms and conditions hereinafter set forth, Landlord hereby grants to Tenant the right of first offer (herein sometimes called the (“Right of First Offer”) during the Term (including any Extension Term) to purchase the Building and Land, or any portion thereof or interest therein (herein referred to as the

“Offered Property”) in the event Landlord elects, at any time daring the Lease Term, to offer the Offered Property for sale. If, during the Lease Term, Landlord elects to offer the Offered Property for Sale, Landlord shall give written notice (“Notice of Offer”) to Tenant setting forth the cash price at which Landlord intends to offer the Offered Property for sale, together with the other material terms and conditions of such offer (herein called the Offer’). Tenant shall have the right, at its option, exercisable as hereinafter provided, to purchase the Offered Property for the price and on the same terms and conditions set forth In the Offer.

B. Exercise. Provided that all the Expansion Conditions are then satisfied, the Right of First Offer shall be exercised, if at all, by Tenant giving written notice of exercise thereof (a “First Offer Notice”) to Landlord within 30 calendar days (the “First Offer Notice Period”) after receipt by Tenant of the Notice of Offer and pursuant to Paragraph 35.A. If Tenant provides Landlord with a First Offer Notice, Tenant shall have three (3) months to close under the terms of the Offer. If Tenant fails to close within such period, then Tenant’s Right of First Offer shall terminate.

C. Non-Exercise. In the event Tenant does not timely exercise its Right of First Offer with respect to any Notice of Offer, Landlord shall have six (6) months to market the Offered Property covered by the subject Offer to any third party who is willing to purchase the Offered Property in accordance with such Offer. If no contract is executed within said six (6) month period, Tenant’s Right of First Offer with respect to the Offered Property shall be reinstated. Should Landlord materially change the economic or financial terms of the Offer presented to Tenant, or enter into a contract or contract amendment which materially changes the economic or financial terms of the Offer presented to Tenant, then such modified or amended Offer or contract, as the case may be, shall constitute a new Offer hereunder and Tenant’s Right of First Offer shall apply thereto, obligating Landlord to present such new Offer to Tenant and entitling Tenant the right to exercise the Right of First Offer as to such new Offer in the manner hereinbefore provided. For the purposes of this Paragraph 35.C., a “material” change in the economic terms of the Offer shall mean a change in the total economic terms of the Offer of greater than or equal to 3%. In the event of any sale to a third party in accordance with the requirements of this Paragraph 35, upon the closing of such purchase this Right of First Offer shall be deemed to automatically expire with respect to the Offered Property and Tenant, at Landlord’s request, shall promptly execute and deliver to Landlord an instrument releasing and quitclaiming any and all interest Tenant would otherwise have under this Paragraph 35 to the purchaser of the Offered Property.

D. Third Party Offers. Any offer made by a third party to Landlord for the purchase of the Offered Property, other than in lieu of condemnation, shall give Tenant the same rights under this Paragraph 35 as if such offer were an offer made by Landlord for the sale of the Offered Property.

E. Exceptions to Right of First Offer. Tenant’s Right of First Offer shall not apply to: (a) any Offered Property acquired by a third party in a condemnation proceeding or a conveyance in lieu of condemnation; (b) any conveyance resulting from the foreclosure of a mortgage or other instrument encumbering the Offered Property, or any deed (or transfer or other form of conveyance or assignment) given or made in lieu of such foreclosure; (c) any transfer by a partnership to any of its partners; (d) any transfer between or among partners; (e) any transfer

to an affiliate of Landlord. As used herein the term “affiliate” means any equity holder of the transferring entity, any corporation or entity owned or controlled, directly or indirectly by the transferring entity.

36. CONSENTS. Whenever under any terms or provisions of this Lease either party’s consent or approval is required or requested or performance by either party of any act or other matter or thing is to be to the satisfaction of or acceptable to the other party, such consent or approval shall not be unreasonably withheld or delayed and such party shall not be unreasonable in withholding its satisfaction or acceptance, always excepting any instance where it is provided that such party may act arbitrarily or at its discretion and any instance in which specific standards for consent or approval are provided In this Lease.

37. TAX CONSEQUENCE OFFSET. Pursuant to the Contribution Agreement and the terms of that certain Amended and Restated Limited Liability Company Agreement for 35 ▇. ▇▇▇▇▇▇ Venture L.L.C. (the “Venture Agreement”), dated of even date hereof, Landlord has agreed to comply with the Transfer Prohibition (as defined in the Venture Agreement) and to maintain a level of non-recourse debt against the Building and the Land sufficient to avoid any adverse tax consequences to Tenant throughout the Restrictive Period (as defined in the Venture Agreement). Pursuant to Section 25 of the Venture Agreement, Landlord has agreed to indemnify Tenant against (I) any violations of the Transfer Prohibition and (ii) Landlord’s failure to comply with the aforementioned debt maintenance requirement. In order to secure Landlord’s indemnity obligations under Section 25 of the Venture Agreement, Landlord and Tenant hereby acknowledge and agree that Tenant shall be permitted to offset against Rent accruing under this Lease if Landlord fails to make any payments in respect of amounts due under the indemnification provisions of Section 25 of the Venture Agreement, an amount equal to the indemnification payments to have been made under said Section 25. Such offset shall be made against Rent next becoming due under this Lease until the offset is fully exhausted. Notwithstanding the foregoing, such offset shall be limited to a maximum of $9,200,000.00.

38. FINANCIAL FORMATION. During each Calendar Year of the Term of this Lease, upon not less than thirty (30) nor more than sixty (60) days written notice from Landlord to Tenant, Landlord and Landlord’s lender may review Tenant’s audited financial statements for the then most recent Calendar Year (to the extent available) at the Premises and under Tenant’s supervision (the ‘Financial Review”). Except as provided below, Landlord and Landlord’s lender shall not perform a Financial Review more than once per Calendar Year (the “Annual Financial Review”) during the Term hereof and Landlord and Landlord’s lender shall not be entitled to copies of such audited financial statements or any supporting documentation. Each Annual Financial Review shall be subject to the Confidentiality Requirements set forth in Paragraph 33 herein. In addition to the Annual Financial Review, Landlord shall have a one time right to conduct a Financial Review, subject to the Confidentiality Requirements, under each of the following circumstances: (I) with the lead underwriter who is managing the underwriting of securities to be offered in connection with the transfer of the ownership interests in the Landlord or the Property to a real estate investment trust or partnership controlled by a real estate investment trust pursuant to the terms of the Venture Agreement; and (ii) following the expiration of the Restrictive Period, with the purchaser or a representative of the purchaser in connection with the sale of the Building after the Restrictive Period. If Landlord foregoes its Annual Financial Review for any Calendar Year, Landlord shall, also have the one time right in that Calendar Year to conduct a Financial Review, subject to the Confidentiality Requirements, under either circumstance (i) or circumstance (ii) above.

IN WITNESS WHEREOF, the parties hereto have executed this Lease as of the date first above written.
