 WITNESSETH: 
  
 1. Premises; Renewal Options. 
  
 (a) Subject to the terms and conditions set forth herein, Landlord hereby agrees to lease the Premises to Tenant, and Tenant hereby agrees to accept the
Premises for the Term, paying as Rent therefore the sums hereinafter provided, without any setoff, abatement, counterclaim, recoupment or deduction whatsoever, except as otherwise set forth herein. Tenant shall also have the non-exclusive right to
use the common areas of the Building for ingress and egress subject to the terms and conditions set forth herein. In addition, Landlord 

  

 14 

 
shall lease to Tenant, and Tenant agrees to lease from Landlord, the Temporary Premises for a period (“Temporary Premises Period”) beginning
with the Commencement Date and ending upon the earlier of (i) a date specified by Tenant in written notice to Landlord delivered at least ninety (90) days prior to such date and (ii) the date which is one calendar year after the Commencement Date.
The leasing of the Temporary Premises shall be subject and pursuant to the terms and conditions set forth herein, including, without limitation, the payment of Base Rent and Additional Rent with respect to the Temporary Space, and all calculations
of Tenant’s Proportionate Share of Expenses and Tenant’s Proportionate Share of Taxes shall include the Temporary Premises. During such time as Tenant retains possession of all or any portion of the Temporary Premises, such Temporary
Premises shall be considered to be part of the Premises for purposes of this Lease. Upon the end of the Temporary Premises Period, Tenant shall vacate the Temporary Premises and surrender the space to Landlord in an “AS IS” “WHERE
IS” condition, without any requirement to remove any of Tenant’s Property or any other property of Tenant located outside of the Temporary Premises or to perform repairs, improvements or other work (other than repairs requested by Landlord
within five (5) days after the date upon which Tenant vacates the Temporary Premises and which are necessary to repair any damage to the Building (other than to the paint, carpeting or wall coverings) caused by the removal of Tenant’s
Property), regardless of whether or not such space, upon delivery to Landlord, complies with the Requirements, provided that Tenant shall not intentionally commit waste in the Temporary Premises. 
  
 (b) Provided that this Lease shall be in full force and effect and Tenant
shall not be in Material Default at the time of exercise of any right of renewal or as of the date set for commencement of the renewal term, Tenant shall have the right to renew the Initial Term for four (4) successive periods of five (5) years
each, on the following terms and provisions: 
  
 (i) Each such renewal term shall be upon the same terms, covenants and conditions as provided in this Lease except as follows: 
  
 (A) the annual Base Rent rate for the renewal terms shall be equal to ninety-five percent (95 %) of the anticipated Fair Market Rental
Value as of the date of the commencement of the relevant renewal term. Upon determination of the Base Rent, the parties shall promptly execute an amendment to this Lease to establish and evidence such Base Rent; 
  
 (B) there shall be no further rights to renew beyond the
four (4) renewal terms specified herein; and 
  
 (C) Tenant shall have the right to renew for all or any portion of the Premises, provided that Tenant’s renewal of space in the office tower portion of the Building shall be in full floor increments (except that Tenant may renew the
79th Floor Premises and for any amount of space on the highest floor other than the 79th floor that is renewed so long as Tenant renews at least approximately one-half of the Rentable Square Feet on such highest floor, and Tenant shall be permitted
on the 25th and 26th floors to renew only the PBX 

  

 15 

 
Space). Notwithstanding the foregoing, the office tower portion of the Premises with respect to which Tenant elects not to renew this Lease (the
“Non-Renewed Premises”) shall be limited to full contiguous floors of the Premises prior to the renewal (not including the 79th floor, the highest floor that is renewed or any space that has been recaptured by Landlord pursuant to
Section 13(c)) which constitute the highest floors contained in the office tower portion of the Premises prior to the renewal; provided, however that in no event shall Tenant be required to delete floors 29-31 nor shall Tenant be required to
delete the PBX Space on the 25th and 26th floors. 
  
 (ii) Tenant shall exercise its right to the renewal terms provided herein, if at all, by notifying Landlord in writing of its election to exercise the right to renew the Term for each additional five (5) year period not less than eighteen
(18) months prior to the then current expiration of the Term, and a failure to give such a notice on or before such date shall constitute a waiver of Tenant’s right to renew. On or before the date that is fourteen (14) months prior to the then
current expiration of the Term, Landlord shall notify Tenant in writing of the Landlord’s determination of the Fair Market Rental Value for the applicable renewal period. If the Tenant objects to such determination, then the parties agree to
negotiate in good faith to resolve the dispute. If Landlord and Tenant are unable to resolve the dispute on or before the date that is twelve (12) months prior to the then current expiration of the Term, then the Fair Market Rental Value shall be
determined by Arbitration, and Landlord and Tenant shall within ten (10) Business Days thereafter give each other notice of the proposed Fair Market Rental Values that they intend to use in the Arbitration; provided that Tenant shall have the right
to rescind its election to renew upon written notice to Landlord within thirty (30) days after Landlord has notified Tenant of the proposed Fair Market Rental Value which Landlord will offer in the Arbitration. If Tenant does not notify Landlord
within such thirty-day period that Tenant is rescinding its election to renew, Tenant shall have no further right to rescind such election and the Arbitration shall proceed with both parties agreeing to be bound by the Fair Market Rental Value
determined thereby. If for any reason a renewal period begins and the Fair Market Rental Value of the Premises has not yet been determined, then Tenant shall pay rent to Landlord for the Premises equal to the Base Rent and Additional Rent that
Tenant was paying in the last month of the Term immediately prior to the applicable renewal period until the Arbitration is resolved. Once the amount of Fair Market Rental Value for the Premises for such renewal period has been determined by the
FMRV Arbitrators, Tenant shall immediately begin paying 95% of the Fair Market Rental Value so determined. If the amount of rent Tenant had been paying is less than the Fair Market Rental Value so determined, Tenant shall pay such difference to
Landlord within fifteen (15) days after such determination. If, however, the amount of rent Tenant had been paying is greater than 95% of the Fair Market Rental Value so determined, Landlord shall refund such difference to Tenant within fifteen (15)
days after such determination. 
  

 16 

 (iii) “Fair Market Rental Value” shall mean the anticipated base rent as
of the commencement of the relevant renewal term at which the Premises, or applicable portion thereof to be renewed, would be leased for the renewal term or for the Expansion Space, in its then-existing condition, in an arms-length transaction
between a willing landlord and tenant in the office space market existing for comparable first-class buildings in the central business district of Chicago, Illinois (taking into account the location of the Building in the central business district),
taking into account all relevant facts and considerations, including base rents, rent escalations, rent abatements, allowances (such as tenant improvement, space planning, working drawing and moving allowances), commencement date of the comparable
leases, commissions, operating expenses, real estate taxes and other economic terms and relevant non-economic terms (including, without limitation, the provision of special services and rights to Tenant) contained in the Lease and in recently signed
leases for premises of similar size, location and configuration in comparable first-class buildings in the central business district of Chicago (taking into account the location of the Building in the central business district and the location of
the Premises within the Building). The Landlord and Tenant hereby agree that the creditworthiness of tenants shall be a relevant factor in determining Fair Market Rental Value hereunder. 
  
 (iv) In connection with the first (1st) and third (3rd) of Tenant’s renewals of the Term after the
Initial Term, Landlord shall, upon written request of Tenant, provide Tenant, prior to the beginning of the applicable renewal term, with a tenant improvement allowance as requested by Tenant, but in any event, which for each renewal shall not
exceed the amount equal to the product of (A) the number of Rentable Square Feet contained in the portion of the Premises being renewed (renewals on partial floors shall be determined in accordance with the Exhibit W Standard) and (B) $30.00 (the
“Renewal Allowance”). Disbursement of the Renewal Allowance shall be subject to all of the terms and conditions of this Lease and the Workletter (including, without limitation, any rent credit or offset rights granted to Tenant for
Landlord’s failure to comply with the provisions hereof). If Tenant elects to receive a Renewal Allowance for the first and/or third renewal period, the Fair Market Rental Value for such renewal period shall take into account that such Renewal
Allowance is to be amortized over the term of such renewal period at a rate equal to one percent (1 %) per annum plus the Prime Rate. 
  
 (v) Notwithstanding anything to the contrary contained herein, in the event the amount of space in the Building being leased by Tenant
falls below three hundred thousand (300,000) Rentable Square Feet, (i) Tenant shall only be permitted to renew the Initial Term for two (2) additional successive five (5) year periods, and (ii) if Tenant elects to renew, Tenant must renew for all of
the space comprising the Premises on the date of the commencement of the relevant renewal term. 
  

 17

Exhibit C payable in monthly installments (herein called “Monthly Base Rent”) in the amount stipulated in Exhibit C, in advance beginning on the Commencement Date and on the first day of each calendar
month thereafter of the Term (subject to any rent abatement set forth herein), and at the same rate prorated for fractions of a month if the Term shall begin on any date except the first day, or shall end on any day except the last day of a calendar

office of the Building, or to such other person, entity or address as otherwise designated from time to time by written notice from Landlord to Tenant. The obligation to pay Rent hereunder is independent of each and every other covenant and
agreement contained in this Lease and shall, except as otherwise set forth herein, be paid without any setoff, abatement, counterclaim, recoupment or deduction; provided, however, notwithstanding anything contained in this Lease to the contrary,
Tenant shall be entitled to: (i) offset against Rent (and any other amounts owed by Tenant to Landlord pursuant to this Lease), any overpayments of the estimated payments made by Tenant with respect to Additional Rent (including, without limitation,
any Additional Rent Progress Payments), as disclosed on the applicable Landlord’s Expense Statement or Landlord’s Taxes Statement (if any) or determined pursuant to a contest as provided in Section 2(f), any other unappealable final

	 	(36)	 	costs of acquiring, installing, moving or restoring objects of art and insurance premiums thereon that are in the aggregate in excess of $5,000 per annum; and

  

	 	(37)	 	any cost associated with Landlord’s relocation, or attempted relocation, of any tenant in the Building. 

  
 In addition, Tenant shall not be charged (and shall receive a credit on that
portion of the Premises that is vacant, which amount per Rentable Square Foot shall be subject to adjustment from time to time by Landlord based upon Landlord’s contract with the janitorial service) for janitorial services for any portion of
the Premises that is vacant, provided that (i) such portion is either an entire floor or is a partial floor which is separately partitioned, (ii) Landlord is not currently performing janitorial services in such space pursuant to Tenant’s
request, (iii) said portion of the Premises is not being used in Tenant’s business operations, other than as storage space and (iv) such exclusion shall commence only upon the first day of a calendar month after written request from Tenant as
set forth in Section 7 hereof. In the event and to the extent Tenant is providing its own janitorial services for the entire Premises in compliance with the terms of Section 7 hereof, then Expenses shall not 

  

 25 

 
include the cost of such janitorial services for other tenants in the Building but shall continue to include the cost of janitorial services with respect to
common areas in the Building. In addition, if Tenant elects not to use the Building cleaning contractor to clean any portion of the Premises (including, without limitation, any computer room, kitchen and similar types of special use areas), then
Tenant shall receive a credit for the Landlord’s Actual Cost of providing basic cleaning service to those areas, provided that the amount of such credit shall in no event exceed the amount of credit, if any, Landlord receives from the Building
cleaning contractor. 
  
 Landlord agrees that it shall use its
good faith efforts to incur Expenses in maintaining and operating the Building at a level that is comparable to and consistent with other first-class office buildings in downtown Chicago, in particular the Comparable Buildings. Upon written request
from Tenant, Landlord shall use good faith efforts to cooperate with Tenant in obtaining expense and tax information on the Comparable Buildings in sufficient detail to be used by Tenant as a comparison of the Expenses and Taxes for the Building.

  
 For any Adjustment Year in which the aggregate Rentable
Square Footage of the office space of the Building has not been ninety-five percent (95%) occupied during all or any portion of such Adjustment Year, Expenses shall, except to the extent Tenant has elected to perform its own janitorial services for
all or a portion of the Premises, include expenses which Landlord shall reasonably determine would have been incurred had the Building been ninety-five percent (95%) occupied for all or the applicable portion of such Adjustment Year provided,
however, that (i) Landlord shall not collect more than 100% of the actual costs incurred in operating the Building from the tenants of the Building and (ii) in no event shall Tenant be liable for more than Tenant’s Proportionate Share for
Expenses (excluding additional costs or charges properly allocable to Tenant which are not common to all of the Tenants in the Building generally). 
  
 Notwithstanding anything to the contrary contained in this Lease, in no event shall Landlord collect and retain more than 100% of the actual costs
incurred in operating the Building from the tenants of the Building. 
  
 (iv) “Taxes” shall mean all real estate taxes, assessments (whether they be general or special), sewer rents, rates and charges, transit taxes, taxes based upon the receipt of rent and all other
federal, state or local governmental taxes, general, special, ordinary or extraordinary (but not including, income taxes, franchise, capital or stock taxes, gift or inheritance taxes, or any other tax imposed upon or measured by Landlord’s
income or profits (unless the same 

  

 26 

 
shall be imposed in lieu of real estate taxes) or any penalties or interest on any Taxes resulting from the late payment thereof) which is now or hereafter
levied, imposed or assessed against the Building or the Land or both and which become due and payable during the Term. Taxes shall also include any personal property taxes imposed upon the furniture, fixtures, machinery, equipment, apparatus,
systems and appurtenances used by Landlord in connection with the Building or the Land for the operation thereof which are due and payable during the Term. 
  
 Notwithstanding the foregoing provisions of this Subsection 2(b)(iv): 
  
 (A) If at any time during the Term of this Lease the method of taxation then prevailing shall be altered so that any new tax, license fee,
assessment, levy, imposition or charge or any part thereof shall be imposed upon Landlord in place or partly in place of any such Taxes, and shall be measured by or be based in whole or in part upon the Real Property or the rents or other income
therefrom, then all such new taxes, license fee, assessments, levies, impositions or charges or part thereof, to the extent that they are so measured or based, shall be included in Taxes levied, imposed, or assessed against Real Property to the
extent that such items would be payable if the Real Property were the only property of Landlord subject thereto and the income received by Landlord from the Real Property were the only income of Landlord. 
  
 (B) Notwithstanding the year for which any such taxes or
assessments are levied, in the case of special taxes or special assessments which may be payable in installments, the amount of each installment due and payable during a calendar year shall be included in Taxes for that year. Except as provided in
the preceding sentence, for purposes of this Section 2, all references to Taxes “for” a particular year shall be deemed to refer to Taxes payable in such year notwithstanding that in each case the assessments for such Taxes may have
been made for a different year or years than the year in which such Taxes are payable. 
  
 (C) The rights of Landlord and Tenant with respect to Tax contests are as set forth in Section 2(j). 
  
 (v) “Tenant’s Proportionate Share for
Expenses” shall, subject to the adjustments provided for in (vii) below, mean the percentage obtained by dividing the number of Rentable Square Feet contained in the Premises by 2,332,000, the Rentable Square Footage of the office tower
portion of the Building. 
  
 (vi)
“Tenant’s Proportionate Share for Taxes” shall, subject to the adjustments provided for in (vii) below, mean the percentage obtained by 

  

 27 

 
dividing the number of Rentable Square Feet contained in the Premises by 2,442,000 square feet, the Rentable Square Footage of the entire Building.

  
 (vii) Landlord and Tenant acknowledge that
although the Premises is measured pursuant to the Exhibit W Standard, the leases with respect to the remainder of the Building contain rentable square foot measurements determined by 1989 BOMA. The numbers set forth in subsections (v) and (vi) above
that comprise the denominators for determining the two Tenant’s Proportionate Share ratios are the aggregate rentable square feet contained in the office tower portion and the Building, respectively, as agreed to between Landlord and Tenant,
which reflects the Rentable Square Feet contained in the Initial Premises (calculated on Exhibit W Standard) and in each other lease of space in the Building in effect as of the Commencement Date (calculated pursuant to 1989 BOMA). Landlord agrees
that with respect to all leases of space in the Building entered into after the Commencement Date (including amendments, modifications, supplements, addenda or restatements of existing leases where existing tenants are leasing new space) (“New
Area Leases”), for purposes of recalculating the denominators set forth in subsections (v) and (vi) above, the rentable square feet of the new or additional area (“Incremental Leased Premises”) demised under the New Area Leases shall
be the Exhibit W Standard (regardless of the actual terms of the New Area Leases). As the space in the Building (other than the Premises) is leased under the New Area Leases, the denominators in subsections (v) and (vi) representing the
aggregate rentable square feet contained in the office tower portion and the entire Building, respectively, shall be increased by the positive difference between (x) the number of rentable square feet contained in the Incremental Leased Premises
pursuant to the Exhibit W Standard (as reflected on Exhibit W), and (y) the rentable square feet contained in the Incremental Leased Premises pursuant to 1989 BOMA (as reflected on Exhibit W). 
  
 As an example of the foregoing, if a lease in effect on the Commencement
Date demises 20,000 rentable square feet of space on a floor of the Building to a particular tenant and the Exhibit W Standard for such space is 22,000 rentable square feet, when a New Area Lease is executed for such space, the aggregate rentable
square footage numbers in subsections (v) and (vi) above shall be increased by 2,000 rentable square feet. 
  
 As a further example, if a tenant under a lease in effect on the Commencement Date amends such lease to add an additional floor to its premises, such
amendment shall be a New Area Lease and such additional floor shall constitute Incremental Leased Premises, and the positive difference between the Exhibit W Standard and the 1989 BOMA measurement for such Incremental Leased Premises shall be
added to the rentable square foot numbers in subsections (v) and (vi) above. 
  

 28 

 
Upon written request of Tenant, not more often than quarterly, Landlord and Tenant shall meet in order to determine any adjustments to the Additional Rent
Progress Payments that may be appropriate as the result of any New Area Leases. Landlord shall indicate on each Landlord’s Expenses Statements and Landlord’s Taxes Statement delivered to Tenant the cumulative effect on and the timing of
changes in the denominators in subsections (v) and (vi) above as a result of all New Area Leases and renewals and amendments increasing the rentable square feet of the applicable premises entered into during the applicable Adjustment Year.

  
 (c) Computation of Additional Rent. Tenant shall pay
Additional Rent for each Adjustment Year determined as hereinafter set forth. Additional Rent payable by Tenant with respect to each Adjustment Year during which an Adjustment Date falls shall be the following amounts: 
  
 (i) the product of Tenant’s Proportionate Share for
Expenses multiplied by the Expenses for such Adjustment Year (herein called the “Expense Adjustment”), plus 
  
 (ii) the product of Tenant’s Proportionate Share for Taxes multiplied by the Taxes for such Adjustment Year (herein called the
“Tax Adjustment”). 
  
 (d) Payments of
Additional Rent; Projections. Tenant shall pay Additional Rent to Landlord in the manner hereinafter provided. Landlord shall use reasonable efforts to provide Tenant with a statement prior to the beginning of each month showing the amount of
Rent, but any failure of Landlord to provide such a statement prior to the beginning of any month shall in no way excuse or delay any payment of Additional Rent from Tenant required herein. If Landlord fails to provide such statement, Tenant shall
pay Rent based on the previous month’s statement until Tenant receives the new statement. 
  
 Subject to Subsection (C) below, Tenant shall make payments on account of the Expense Adjustment and Tax Adjustment (such payments with respect to any Adjustment Year being called an “Additional Rent
Progress Payment” and, in the aggregate, the “Additional Rent Progress Payments”) effective as of the Adjustment Date for each Adjustment Year as follows: 
  
 (A) Landlord may, prior to each Adjustment Date or from time to time during the Adjustment Year in which
such Adjustment Date falls (but not more than two times each for Taxes and Expenses each Adjustment Year, including the initial Projection Notice), deliver to Tenant a written notice or notices (“Projection Notice”) setting forth
(1) Landlord’s reasonable estimates, forecasts or projections (collectively, the “Projections”) of Expenses and Taxes for such Adjustment Year based on Landlord’s budgets of Expenses and estimate of Taxes, and (2)
Tenant’s Additional Rent Progress Payments with respect to 

  

 29 

 
each component of Additional Rent for such Adjustment Year based upon the Projections. 
  
 (B) With respect to Expenses, until such time as Landlord furnishes a Projection Notice for an Adjustment
Year, Tenant shall, at the time of each payment of Monthly Base Rent, pay to Landlord a monthly installment of an Additional Rent Progress Payment with respect to the Expenses component of Additional Rent equal to the greater of the latest monthly
installment of an Additional Rent Progress Payment for Expenses or one-twelfth (1/12) of Tenant’s latest determined Expense Adjustment. On or before the first day of the first calendar month following Landlord’s service of a Projection
Notice (or if the Projection Notice is delivered after the fifteenth day of a month, then the second calendar month following service of such Projection Notice), and on or before the first day of each month thereafter, Tenant shall pay to Landlord
one-twelfth (1/12) of the Expenses component of the Additional Rent Progress Payments shown in the Projection Notice. Within thirty (30) days following Landlord’s service of a Projection Notice, if the Projection Notice indicates an increase in
the Expenses component of the Projection for the Adjustment Year, then Tenant shall also pay Landlord a lump sum equal to the Expenses component of the Additional Rent Progress Payments which, according to the Projection Notice, should have been
paid to date less any previous payments on account of the Expenses component of Additional Rent Progress Payment made during such Adjustment Year. 
  
 (C) Except as provided below, Tenant shall not be obligated to make monthly Additional Rent Progress Payments with respect to
Tenant’s obligation hereunder to pay Tenant’s Proportionate Share for Taxes. Tenant shall, therefore, pay to Landlord (or as directed by Landlord in writing), beginning with Taxes due and payable in the Spring of 1999, Tenant’s
Proportionate Share for Taxes of each installment of Taxes within two (2) weeks after receipt of a bill from Landlord relating to such installment of Taxes. During such time as a Material Default exists and is continuing, Tenant shall, at the time
of each payment of Monthly Base Rent, pay to Landlord a monthly installment of Additional Rent Progress Payment with respect to the Taxes component of Additional Rent equal to one-twelfth (1/12) of the Tenant’s latest determined portion of
Taxes for the applicable Adjustment Year (“Monthly Tax Deposits”). Tenant shall in no event be required to make any payments with respect to Taxes that become due and payable outside of the Term of this Lease. 
  
 By way of example based on current real estate billing procedures, provided no Material
Default exists, Tenant’s first payment toward Taxes shall be with respect to the first installment of 1998 Taxes payable in 1999, at which time Tenant shall pay Tenant’s Proportionate Share for Taxes of the entire amount of such
installment. Likewise, assuming the Term ends on November 30, Tenant’s last payment toward Taxes shall be for the second 

  

 30 

 
installment payable in the last calendar year of the Term, at which time Tenant shall pay Tenant’s Proportionate Share for Taxes of the entire amount of
such installment. 
  
 (e) Readjustments. The following
readjustments with regard to the Tax Adjustment and Expense Adjustment shall be made by Landlord and Tenant: 
  
 (i) Following the end of each Adjustment Year and after Landlord shall have determined the amounts of Expenses to be used in calculating
the Expense Adjustment for such Adjustment Year, Landlord shall notify Tenant in writing (“Landlord’s Expenses Statement”) of such Expenses for such Adjustment Year. The Landlord’s Expenses Statement shall be prepared by
Landlord, with audit by PricewaterhouseCoopers, or such other nationally recognized public accounting firm used by Landlord, which is reasonably acceptable to Tenant (“Landlord’s Accountant”). Landlord agrees to use reasonable
efforts to deliver the Landlord’s Expenses Statement to Tenant by May 1 of any Lease Year and will deliver such statement in any event by June 1. If the Expense Adjustment owed for such Adjustment Year exceeds the Expense Adjustment component
of the Additional Rent Progress Payment paid by Tenant during such Adjustment Year, then Tenant shall, within thirty (30) days after the date of Landlord’s Expenses Statement, pay to Landlord an amount equal to the excess of the Expense
Adjustment over the Expense Adjustment component of the Additional Progress Payment paid by Tenant during such Adjustment Year. If the Expense Adjustment component of the Additional Rent Progress Payment paid by Tenant during such Adjustment Year
exceeds the Expense Adjustment owed for such Adjustment Year, then at Tenant’s election, Landlord shall either credit such excess (plus, if such excess is greater than ten percent (10%) of the Expense Adjustment component of the Additional Rent
Progress Payment paid by Tenant, interest at the Prime Rate for the amount of each monthly deposit of Additional Rent that was in excess of 1/12th of the actual Expense Adjustment) against the next Rent coming due hereunder or, within thirty (30)
days after the date of Landlord’s Expenses Statement, pay to Tenant an amount equal to such excess (including such interest, if applicable), provided that if Landlord fails to make such payment when due, Tenant shall have a right of setoff for
such amount against the next Rent coming due hereunder. 
  
 (ii) To the extent Tenant is paying Additional Rent Progress Payments with respect to Taxes, following the end of each Adjustment Year and after Landlord shall have determined the actual amounts of Taxes to be used in
calculating the Tax Adjustment for such Adjustment Year, Landlord shall notify Tenant in writing (“Landlord’s Taxes Statement”) of such Taxes for such Adjustment Year. If the Tax Adjustment owed for such Adjustment Year exceeds
the Tax Adjustment component of the Additional Rent Progress Payment paid by Tenant during such Adjustment Year, then Tenant shall, within two (2) weeks after the date of Landlord’s Taxes Statement, pay to Landlord an amount equal to the excess
of the Tax Adjustment over the Tax Adjustment 

  

 31 

 
component of the Additional Rent Progress Payment paid by Tenant during such Adjustment Year. If the Tax Adjustment component of the Additional Rent Progress
Payment paid by Tenant during such Adjustment Year exceeds the Tax Adjustment owed for such Adjustment Year, then at Tenant’s election, Landlord shall either credit such excess against the next Rent coming due hereunder or, within thirty (30)
days after the date of Landlord’s Taxes Statement, pay to Tenant an amount equal to such excess. 
  
 (iii) In the event either party hereunder owes the other party amounts pursuant to this Subsection 2(e) and such amounts due are
not paid within the time periods specified, then the party owing such amount shall pay interest to the other party at the Prime Rate on the amount remaining unpaid from the date such payment is due until such amounts are paid. 
  
 (f) Books and Records. Landlord shall maintain books and records
showing Expenses and Taxes and the payments and/or reimbursements received by or owed to Landlord with respect thereto in accordance with sound accounting and management practices. Tenant may examine such books and records at reasonable times upon
reasonable prior written notice within one hundred twenty (120) days after the delivery of a Landlord’s Expense Statement. In addition, Landlord shall, simultaneously with the delivery of each bill relating to an installment of Taxes or
Landlord’s Taxes Statement, provide Tenant with copies of the applicable real estate tax bills and assessment notices received by Landlord with respect to the Building and such other information and data related to Taxes as Landlord may receive
from the tax assessor or other governmental authority, provided Landlord shall not be required to provide Tenant with copies of any leases of other tenants in the Building, nor any of the other economic terms or confidential information contained in
said leases. If Tenant does not object in writing to any Landlord’s Statement within twelve (12) calendar months after its delivery to Tenant, then the determination of Expenses and Taxes set forth therein shall be deemed correct and not
subject to review by either party. In the event Tenant takes exception to any item or items set forth in either Landlord’s Expense Statement or Landlord’s Taxes Statement (“Contested Matters”) and gives Landlord written
notice thereof within said twelve (12) month period, then, within thirty (30) days after Landlord’s receipt of such notice from Tenant, Landlord and Tenant shall work in good faith toward resolving the Contested Matters. If, after the
expiration of such thirty (30) day period, any of the Contested Matters remain unresolved (the “Unresolved Contested Matters”) the Landlord and Tenant shall agree on a mutually acceptable major national public accounting firm other
than Landlord’s Accountant (“Major Accounting Firm”) to resolve the dispute between Landlord and Tenant solely with respect to the Unresolved Contested Matters. Landlord and Tenant agree to be bound by the decision of said
Major Accounting Firm with respect to the Unresolved Contested Matters. Tenant shall pay the charges of the Major Accounting Firm unless the Major Accounting Firm determines that Tenant was overcharged in excess of three percent (3%) of the amount
set forth as actually due from Tenant on the relevant Landlord’s Statement, in which event Landlord shall pay the charges of the Major Accounting Firm. 
  

 32 

 If any Contested Matter is resolved by settlement in favor of Tenant, or if any Unresolved Contested
Matter is resolved by settlement or by the Major Accounting Firm in favor of Tenant, then, in addition to a prompt refund of the overcharge, Tenant shall be entitled to interest on the amount of such overcharge in excess of ten percent (10%) of the
amount set forth on the applicable Landlord’s Statement from the date such charges were paid to the date of Landlord’s refund at a rate per annum equal to two percent (2%) per annum plus the Prime Rate. Tenant shall have the right
to credit the amount of such refund, and such interest, against the next Rent coming due hereunder. 
  
 (g) Proration and Survival. With respect to any Adjustment Year which does not fall entirely within the Term, Tenant shall be obligated to pay as
Additional Rent for such Adjustment Year only a pro rata share of Additional Rent as hereinabove determined, based upon the number of days of the Term falling within the Adjustment Year. Following expiration or termination of this Lease, Tenant
shall pay any Additional Rent due to the Landlord, or Landlord shall refund to Tenant any excess Additional Rent paid to Landlord, within thirty (30) days after the date of Landlord’s Statement sent to Tenant (or with respect to Taxes within
thirty (30) days after the date Landlord receives a refund of any portion of Taxes for a prior Adjustment Year). Without limitation on other obligations of Landlord and Tenant which shall survive the expiration of the Term, the obligations of
Landlord to refund any Additional Rent and the obligations of Tenant to pay Additional Rent provided for in this Section 2 shall survive the expiration or termination of this Lease. Each Landlord’s Statement upon delivery to Tenant
shall, with respect to Landlord, be deemed to be final and Landlord shall not thereafter charge or attempt to charge Tenant with any loss, cost, damage or expense incurred in any Adjustment Year for which Landlord has previously issued a
Landlord’s Statement; provided, however, Landlord may issue a correction to a Landlord’s Statement within twelve (12) months after delivery of the relevant Landlord’s Statement, and the period within which Tenant may contest a matter
which is the subject of such a correction statement shall be the twelve (12) month period after receipt of such correction statement. 
  
 (h) No Decrease in Base Rent. In no event shall any Additional Rent result in a decrease of the Base Rent payable hereunder as set forth in
Section 2 hereof. 
  
 (i) Additional Rent. All amounts
payable by Tenant as or on account of Additional Rent shall be deemed to be Additional Rent becoming due under this Lease. 
  
 (j) Right to Contest Taxes. (i) Landlord shall contest the Taxes imposed for each calendar year all or any portion of which falls within the Term.
Landlord shall diligently pursue each such contest until a final, non-appealable decision is rendered; provided, however, that if Landlord believes in its commercially reasonable judgement that it is in the best interest of the Building and its
tenants to settle or terminate any contest then Landlord may do so in its sole determination. Landlord shall at all times keep Tenant informed of the progress of each such contest. If the Building is sold during the Term, Landlord shall use
reasonable efforts to minimize any increase in Taxes resulting from such sale. 
  

 33 

 (ii) In the event Landlord does not protest the Taxes for any calendar year, as provided in Section
2(j)(i) above, so long as Tenant satisfies the Tenant Leasing Requirement, Tenant, at Tenant’s sole cost and expense, may pursue such contest on its own behalf and on behalf of the Building; provided, however, that Tenant shall at all times
in connection with any such Proceedings act in good faith and shall use reasonable efforts to achieve an outcome that is reasonably acceptable to both Landlord and Tenant. In addition to Tenant’s obligation to act reasonably and in good faith,
Tenant may not settle any contest without the prior written approval of Landlord, which may be withheld in Landlord’s sole discretion. Landlord hereby authorizes Tenant to appear in such Proceedings on behalf of Landlord and, if necessary,
Landlord shall execute any such reasonable documents or statements to evidence such authority. If Landlord’s participation in the Proceedings shall be required, Tenant shall provide Landlord with written notice of such fact instructing Landlord
to undertake jointly with Tenant the desired Proceedings. All reasonable costs and expenses incurred by Landlord as a result of such participation, including reasonable attorney’s fees, shall be included in Expenses for such calendar year. Any
costs and expenses incurred by Tenant in contesting Taxes shall, to the extent such Taxes are actually reduced, be reimbursed by Landlord and Landlord may include such reimbursement in Expenses for the Adjustment Year in which such reimbursement is
made. 
  
 (iii) In the event Tenant shall contest the Taxes, as
set forth above, Landlord shall provide Tenant and Tenant’s attorneys with all necessary books, records and other relevant information to properly and effectively conduct the contest including, without limitation, information for the applicable
calendar year concerning income from the Building and the amount of vacant space during such calendar year. 
  
 (iv) In the event any refund or reduction in Taxes is achieved, whether by Landlord or Tenant, Landlord shall within thirty (30) days after receipt of a
refund (or if Landlord has not paid and therefore is not entitled to a refund of the contested Taxes, the date of such determination) either pay to Tenant Tenant’s Proportionate Share for Taxes thereof or allow Tenant to credit the same against
future payments of Rent coming due under this Lease. 
  
 3. Use
of Premises. Tenant shall use and occupy the Premises for executive and general offices, for such related purposes, provided that such purposes are permitted under applicable zoning ordinances and are not inconsistent with a first class office
building and for no other purpose. Tenant shall not use or occupy the Premises or permit the use or occupancy of the Premises for any purpose or in any manner which (a) is unlawful or in violation of any applicable Requirement or (b) invalidates,
increases or clearly will invalidate or increase the amount of premiums for any policy of insurance affecting the Building, unless any additional amounts of insurance premiums so incurred, are paid by Tenant to Landlord. 
  
 4. Contraction Option. (a) Tenant shall have several contraction
options with respect to the Premises on the terms set forth below. Provided that Tenant is not in Material Default under this Lease, Tenant shall have the right, exercisable in each instance upon not less than twelve (12) months prior written notice
to Landlord (the “Contraction Notice”), to 
  

 34 

 
reduce the size of the Premises (the “Contraction Right(s)”) by surrendering portions thereof (the “Surrendered Space”) to
Landlord effective as set forth below: 
  

	 Contraction Space Allowed

	 	 Effective Date of Contraction

	 180,000 (or less) RSF
	 	 December 11, 2001

	 180,000 (or less) RSF
	 	 December 11, 2003

	 130,000 (or less) RSF
	 	 December 11, 2005

  
 In addition to the
foregoing Contraction Rights, in the event Tenant has exercised at least two (2) of the foregoing three (3) Contraction Rights, Tenant shall have one (1) additional Contraction Right which shall be, if exercised, effective on December 11, 2007, upon
the terms set forth in this Section 4, provided however that (i) the maximum amount of space by which Tenant may contract the Premises with this additional Contraction Right shall be 120,000 Rentable Square Feet and (ii) the amount of space
by which Tenant contracts the Premises pursuant to this additional Contraction right shall in no event cause the Premises to contain less than 300,000 Rentable Square Feet. 
  
 The exercise by Tenant of the foregoing Contraction Rights shall be subject to the following conditions: (i) the Premises
may only be contracted by up to the number of Rentable Square Feet set forth above in the specified year and, to the extent Tenant does not exercise its Contraction Rights in any of the above-specified years with respect to the permitted amount of
space, Tenant will have waived its right with respect to the balance of such space for that year and in no event may the amount of unexercised contraction space be carried over to the next contraction option, (ii) the space in the office tower
portion of the Building which may be deleted from the Premises as a result of the exercise of Tenant’s contraction options shall (A) be deleted in full floor increments (except that Tenant may delete any amount of space from the highest floor
of the remaining office tower portion of the Premises so long as Tenant retains at least approximately one-half of the Rentable Square Feet on such floor, and Tenant may delete all of the 79th Floor Premises and all of the 25th and 26th floors other
than the PBX Space), (B) be located on contiguous floors of the Premises prior to the contraction (not including the 79th Floor Premises, or any space that has been recaptured by Landlord pursuant to Section 13(c)) so that the remaining
office tower portion of the Premises, after giving effect to such contraction, shall be located on contiguous floors (except the 79th Floor Premises, the 29th through 31st floors and the PBX Space on the 25th and 26th floors and not considering any
space recaptured by Landlord pursuant to Section 13(b)), and (C) constitute the highest floors contained in the office tower portion of the Premises prior to the contraction (not including the 79th Floor Premises); provided, however that in no event
shall Tenant be required to delete floors 29-31 as part of the contraction nor shall Tenant be required to delete the PBX Space on the 25th and 26th floors. 
  

 35 

 The Contraction Notice shall specify the size, location and configuration of the Surrendered Space. The
size of the Surrendered Space shall be determined, subject to the limitations set forth above, in Tenant’s sole discretion. The Surrendered Space shall be in a legally leasable configuration, provided that to the extent the Tenant elects to
contract the Premises on only a portion of a floor, the space contracted from the Premises shall have reasonable access to the elevator lobbies and bathrooms on that floor. 
  
 (b) In the event that the Surrendered Space constitutes less than all of the space occupied by Tenant on a given floor or
floors of the Building, then Tenant shall pay to Landlord, upon demand, one-half of Landlord’s Actual Costs of the construction of the demising walls necessary to segregate and demise the portion of the Premises remaining on such floor and to
provide access for such Surrendered Space to the elevator lobbies and bathrooms on that floor and Tenant shall be responsible for no other costs or expenses. 
  
 (c) Except as otherwise provided in Section 6 or Section 9 hereof, Tenant shall deliver the Surrendered Space to Landlord in an “AS
IS” “WHERE IS” condition, without any requirement to remove Tenant’s Property or to perform repairs, improvements or other work, regardless of whether or not such space, upon delivery to Landlord, complies with Requirements,
provided that Tenant shall repair any damage to the Building (other than to the paint, carpeting or wall covering) caused by the removal of Tenant’s Property upon request of Landlord delivered within five (5) days after Tenant has vacated the
Surrendered Space and shall remove the Structural Alterations that Landlord required Tenant to remove as a part of Landlord’s consent to such Structural Alterations pursuant to Section 6(d). Except as expressly set forth in this
Section 4, Tenant shall not be liable for any fee, charge or other payment because of such contraction, including, without limitation, a fee to reimburse Landlord for its unamortized costs associated with this Lease (e.g., brokerage costs).

  
 (d) Following the Effective Date of Contraction (if any), the
term “Premises” under the Lease shall no longer consist of the Surrendered Space, and Landlord and Tenant shall execute a modification to the Lease to reflect such surrender and to amend such other terms and provisions of the Lease
which are affected by a reduction in the size of the Premises, including, but not limited to, the Base Rent, Tenant’s Proportionate Share for Expenses and Tenant’s Proportionate Share for Taxes. 
  
 5. Leasing Restrictions. 
  
 (a) Landlord shall not, without the express written consent of Tenant (which
consent may be withheld in Tenant’s sole discretion), lease any portion of the Building to any foreign consulates or any agency, department or bureau of any foreign government or any political subdivision thereof. 
  
 (b) Landlord shall only lease space in the Building to tenants which are
consistent with a first-class office building in downtown Chicago. 
  

 36 

 6. Alterations. 
  
 (a) Tenant shall not, without the prior written consent of the Landlord in each instance (which consent shall not be
unreasonably withheld or delayed), make any alterations, improvements or additions to the Premises which: (i) affect the structural integrity of the Building or (ii) affect the Building Systems, load bearing structures or facade of the Building
(herein collectively referred to as, “Structural Alterations”); and 
  
 (b) Notwithstanding anything to the contrary in Section 6(a), Tenant may (i) make cosmetic or decorative type changes to the Premises, including, without limitation, painting, wallcovering, carpeting or other
floor covering and installation or movement of moveable work stations (“Cosmetic Alterations”), or (ii) other alterations, improvements or additions that do not constitute Structural Alterations (collectively with Cosmetic
Alterations, the “Nonstructural Alterations”) including, without limitation, the construction, relocation or removal of all interior non-load bearing walls, sheetrock partitions, doors, doorways, electrical wiring, conduit
(including, without limitation any floor coring), light fixtures, electrical/power/voice/data outlets, air diffusers, ducts, VAV boxes, all carpentry and such other items of Tenant’s Property, in each case to the extent the same do not
constitute Structural Alterations. 
  
 (c) Tenant shall, prior to
commencing any Structural Alterations: (i) notify the building manager in writing of Tenant’s intent to make such alterations (“Alteration Notice”), and (ii) comply with all other requirements of this Section 6.
Concurrently with the delivery of an Alteration Notice, Tenant shall deliver to Landlord the plans and specifications required to be delivered pursuant to the terms of the Workletter. 
  
 (d) Landlord may impose such conditions to the making of Structural Alterations as Landlord deems appropriate in its sole
discretion. Landlord may, as part of Landlord’s consent, require Tenant in writing to remove and restore at the end of the Term any Structural Alterations Tenant makes, provided that Landlord may not impose any additional requirements on Tenant
to remove such Structural Alterations after Landlord has granted its consent. Additionally, Tenant shall secure permits necessary for such work and, subject to the terms hereof, schedule the use of elevators and the timing of such alterations so as
to minimize interference with other tenants in the Building and the use of Building Systems. Notwithstanding the foregoing, in no event shall Landlord require Tenant to obtain payment or performance bonds from the contractors or subcontractors
performing the alterations. 
  
 (e) The work necessary to make any
Structural Alterations to the Premises shall be done at Tenant’s expense by employees of, or contractors hired by, Tenant and approved by Landlord, which approval shall not be unreasonably withheld or delayed. With respect to Nonstructural
Alterations, the work shall be done at Tenant’s expense and Tenant shall use contractors that will not interfere with labor relations at the Building and shall cause such Nonstructural Alterations to be performed in a manner which will not
unreasonably interfere with Building operations. Tenant shall be responsible, at Tenant’s sole cost and expense, for obtaining all proper permits and licenses for all Structural and Nonstructural Alterations, 
  

 37 

 
provided that Landlord agrees that it shall cooperate and assist Tenant and its contractors in any reasonable manner to obtain such permits and licenses, as
set forth in the Workletter. Tenant shall promptly pay to its contractors the cost of all such work and of all decorating required by reason thereof. All work done by Tenant or its contractors pursuant to this Section 6 shall be done in a
first-class workmanlike manner using only good grades of materials and shall comply with all insurance requirements (to the extent Landlord has notified Tenant of such insurance requirements prior to commencement of such work) and all Requirements.
Notwithstanding anything to the contrary contained herein, the terms of the Workletter shall only apply to (i) the initial buildout of space added to the Premises pursuant to Tenant’s exercise of the Expansion Option described in Section
38 or the right of first offer described in Section 39, (ii) to any work for which Landlord provides Tenant a tenant improvement allowance and (iii) Structural Alterations. 
  
 7. Services. (a) The Landlord, subject at all times to Subsection 7(c), shall furnish throughout the Term:

  
 (i)(A) Air-conditioning and heat when
necessary to provide a temperature condition required to meet the performance standards set forth in Exhibit L attached hereto and made a part hereof in the Premises during normal business operations, daily from 7:00 a.m. to 6:00 p.m.
(Saturdays 8:00 a.m. to 1:00 p.m.), Sundays and Holidays (as hereinafter defined) excepted (“Business Hours”). The furnishing of extra or additional air-conditioning and heat at other times shall be subject to the terms of Subsection
(vii). The term “Holidays” currently means the following days: New Year’s Day, Memorial Day, July 4th, Labor Day, Thanksgiving Day, and Christmas Day; 
  
 (B) Notwithstanding anything to the contrary contained in this Lease, in the event Landlord fails to
maintain the temperatures required pursuant to this Section 7(a) such that the actual average temperature in the Premises during Business Hours varies from the temperature required to be maintained during Business Hours as set forth in this
Section 7(a) by at least three (3) degrees Fahrenheit, then such condition shall be deemed to be a Reduction of Services. If Landlord fails to meet the performance standards set forth in Exhibit L as aforesaid, then in addition to
Tenant’s remedies, if any, for interruption of services set forth elsewhere in this Lease, Landlord agrees that within twenty-four (24) hours of Landlord’s receipt of a written notice from Tenant, Landlord, at Landlord’s sole cost and
expense, shall extend the operating hours of the HVAC System if such extension would either correct or mitigate any failure to meet the temperature specifications and deliver service from the HVAC System that is in compliance with the standards set
forth in this Section 7(a). 
  
 If due to a change
in Tenant’s density of personnel or equipment from the concentration in existence on the date of this Lease, the temperature or humidity in the Premises or the Building is adversely affected, Landlord may send written notice to Tenant to cure
such condition, whereupon Tenant shall, at Tenant’s 

  

 38 

 
sole cost and within a reasonable time thereafter, either (1) restore Tenant’s use of the Premises to its prior condition or, (2) upon prior notice to
and approval by Landlord (which approval shall not be unreasonably withheld or delayed) install supplementary air conditioning units or cooling equipment within the Premises sufficient to cure the condition. If Tenant fails to effect the cure
described in clause (1) or clause (2) of the foregoing sentence within thirty (30) days after receipt of Landlord’s notice, Landlord may thereafter install supplementary air conditioning units or cooling equipment in the Premises. If
supplementary air conditioning units or cooling equipment are so installed within the Premises (whether by Tenant or Landlord), Tenant shall pay all costs of installation, operation and maintenance thereof. Tenant acknowledges that Landlord’s
ability to provide air-conditioning to the Critical Area in a manner which meets the specifications set forth in Section 7(a) is dependent upon supplemental air-conditioning units and cooling equipment which were installed and shall be
maintained and operated by Tenant at its sole expense, provided that Landlord shall be responsible for providing chilled water and electricity to such supplementary units and equipment in accordance with the terms of this Lease. 
  
 (ii) (A) Cold water in common with other tenants from City
of Chicago mains for drinking, lavatory, and toilet purposes, drawn through fixtures installed by the Landlord, or by Tenant in the Premises with Landlord’s written consent (which consent will not be unreasonably withheld), from the regular
Building supply. Landlord will supply the lavatory sinks with warm water. In addition, Tenant, at its sole cost and expense, may install, maintain and operate its own hot water heaters in compliance with Requirements. Tenant shall pay Landlord in
accordance with Landlord’s then current rate schedule (but in no event higher than the Most Favored Tenant Rate) for water furnished for any other purpose. Tenant shall not waste or permit the waste of water. 
  
 (B) In the event no water is provided to the Premises or if
the water service provided to the Premises would not permit Tenant, without violating the Requirements, to allow employees to use the Premises or the affected portions thereof, then such conditions shall be deemed a Reduction of Services.

  
 (iii) (A) Janitor service and customary
cleaning provided nightly in and about the Premises, Saturdays, Sundays, and Holidays excepted, in accordance with the Cleaning Specifications. Landlord shall not be required to provide any additional cleaning service beyond the Cleaning
Specifications for any portions of the Premises used for preparation, serving or consumption of food or beverages, training rooms data processing and reproducing operations, data center, private lavatories or toilets or other special purposes
requiring greater or more difficult cleaning work than office areas or to provide additional janitorial service and Tenant agrees, at Tenant’s expense, to do the cleaning itself or retain Landlord’s cleaning contractor or an Acceptable
Cleaning Service (as 

  

 39 

 
hereinafter defined) to perform such cleaning and Landlord shall not charge any fees in connection therewith. Landlord shall use reasonable efforts to cause
its cleaning contractor to schedule the order of cleaning of each floor of the Premises according to Tenant’s written request, subject to Section 12(e), provided that Landlord shall not be required to provide such scheduling if it would
increase Landlord’s costs in connection with the provision of janitorial services unless Tenant agrees to pay such increased costs. 
  
 (B) In the event Tenant shall elect to use a separate janitorial or cleaning service to clean the Premises, then, subject to the terms and
conditions set forth below, Tenant shall have the right upon at least three (3) months’ prior written notice to Landlord to provide its own janitorial services for cleaning of the interior office space of the Premises. The janitorial or
cleaning service employed by Tenant shall be (x) a reputable company with experience in cleaning first-class office buildings in downtown Chicago, and (y) licensed and bonded and shall employ members of a recognized labor union to perform such
janitorial services, or (z) such other janitorial or cleaning service that is reasonably acceptable to Landlord (“Acceptable Cleaning Service”), provided that the cleaning contractor for the Building at the time qualifies as an
Acceptable Cleaning Service. If the cleaning contractor for the Building does not so qualify, Tenant shall only be obligated to employ a janitorial or cleaning service which meets the same criteria as the Building cleaning contractor. In addition,
the performance of such janitorial services shall not adversely affect the operations of the Building. Landlord and Tenant in such case shall use good faith efforts to cause their cleaning contractors to work in harmony. If Tenant elects to use a
separate cleaning service (or its own employees) then Tenant and/or Tenant’s cleaning contractor shall have (1) the exclusive use of all janitorial closets located on floors on which the Premises comprise the full floor and (2) the use in
common with Landlord’s cleaning contractor of the locker room facilities located on the Lower Level One (LL1) (or such separate but similar facilities as Landlord shall provide) and all janitorial closets located on floors on which the Premises
comprise a portion of the floor, provided such use by Tenant or its cleaning contractor shall not result in any additional rent or other charges to Tenant or its contractor and such spaces or facilities shall not be deemed to be a part of the
Premises; 
  
 (iv) The use of all passenger
elevators (and all elevator cabs) servicing the Premises as of the Commencement Date, which use shall be in common with Landlord and other tenants in the Building, which elevators servicing the Premises shall be in operation twenty-four (24) hours
each day, seven days each week, Holidays excepted, and freight elevator service in common with Landlord and other tenants, daily from 7:00 a.m. to 6:00 p.m., Saturdays, Sundays and Holidays excepted Except with respect to the twentieth (20th) floor,
throughout the Term, the floors Occupied by Tenant will not be used by other tenants of the Building as designated elevator transfer floors between elevator 

  

 40 

 
banks. Subject to prior reservations of other tenants in the Building and the Rules and Regulations, Tenant may use the freight elevators in the Building on
a daily basis from 7:00 a.m. to 6:00 p.m. (“Freight Hours”) at no additional charge on a reservation basis. In addition, Tenant may use the freight elevators for deliveries before or after such hours so long as an employee of Tenant
is present to receive the delivery or as otherwise agreed by Landlord and Tenant. Notwithstanding the foregoing, so long as Tenant satisfies the Tenant Occupancy Requirement, Tenant shall have the sole and exclusive use of the Tenant’s Freight
Elevator twenty-four (24) hours a day, seven days per week (including Holidays), without prior notice, but otherwise on the terms set forth herein. Tenant, however, shall, except as otherwise set forth herein, be obligated to reimburse Landlord in
accordance with Landlord’s Actual Cost incurred in operating Tenant’s Freight Elevator (or, if applicable, any of the other freight elevators) (“Freight Elevator Expenses”) during weekends, Holidays and after Freight Hours
(“Late Hours”) if Landlord is required, as a result of Tenant’s use, to incur any additional expense for an elevator operator to operate the freight elevator. In the event Tenant or Tenant’s Contractors and Landlord or
other tenants in the Building also reserve the use of any of the freight elevators during the Late Hours, or if it is a combination of Tenant’s use and the use by other tenants or Landlord in the Building that results in the need for an
elevator operator, then the Freight Elevator Expenses shall be equitably allocated by Landlord among Landlord, Tenant and all such tenants. In addition, Landlord shall daily during the Late Hours provide to Tenant all passenger elevators with access
to the Premises for use by Tenant or Tenant’s Contractors as freight elevator service, provided that Tenant properly pads and otherwise protects the interior of such elevator cabs and repairs any damage caused by Tenant’s use thereof.
Subject to Tenant’s schedule for using Tenant’s Freight Elevator, Tenant shall permit Landlord and other tenants in the Building, upon at least twenty-four (24) hours request (other than in the event of an emergency), to use Tenant’s
Freight Elevator when freight requirements for the Building exceed the capacity of the other Building freight elevators or when the other Building freight elevators are unavailable as a result of repairs. Landlord shall reimburse Tenant, or shall
cause Tenant to be reimbursed, for any costs incurred by Tenant in connection with such use. Regardless of whether Tenant has exclusive use of Tenant’s Freight Elevator, Landlord agrees that, throughout the Term, Tenant may use and Landlord
will not remove or impair the medical phone line located in Tenant’s Freight Elevator. 
  
 In the event Landlord provides four (4) or fewer passenger elevators (each with two elevator cabs) to service each floor of each elevator
bank servicing the Premises, such failure shall be deemed to be a Reduction of Services; 
  
 (v) (A) Electricity shall not be furnished by Landlord, but shall be furnished by an approved electric utility company serving the area.
Landlord 

  

 41 

 
shall permit the Tenant to receive such service direct from such utility company at Tenant’s cost, and shall permit Landlord’s wire and conduits,
to the extent available, suitable, and safely capable, to be used for such purposes. Subject to Section 7(a)(v)(B), Landlord shall continuously during the entire Term provide electrical service to the Premises equal to the electrical service set
forth on Exhibit N. In addition, Landlord covenants that the Building’s wires and conduits shall continue to be available, suitable and safe to carry such electrical service set forth on Exhibit N during the Term. Tenant shall pay
for all charges for electric current consumed on the Premises during Tenant’s occupancy thereof; provided, however, electric current consumed on the Premises in connection with any Building Systems, including, without limitation, emergency
lighting, exit lights, fire alarms, fire sprinklers and other alarms and detectors, shall not be billed directly to Tenant, but shall be included in the Expenses of the Building. The electricity used during the operation of any special air
conditioning systems which may be required for data processing equipment or for other special equipment or machinery installed by Tenant or the data center, shall be paid for by Tenant. Tenant shall be permitted, at its sole cost and expense, to
upgrade the electrical service to the Premises above that provided on Exhibit N, with the prior written consent of the Landlord, which consent shall not be unreasonably withheld or delayed, provided that Landlord may impose conditions
upon the performance of the upgrade as Landlord deems appropriate in its sole discretion; provided, further, that in no event may such upgrade of service exceed the existing Building capacity pursuant to the existing Building specifications unless
Tenant agrees to pay all costs of such Building upgrade, in which event Landlord shall cause such upgrade to be completed but shall not be required to commence such upgrade until Tenant and Landlord have agreed upon the actual costs to be incurred
by Landlord in connection with such upgrade. All alterations or additions to the electrical system permitted to be made by Tenant must conform to all Requirements. Electricity used during janitorial services, alterations and repairs in and to the
Premises shall be paid by Tenant. 
  
 (B)
Landlord shall not in any way be liable or responsible to Tenant for any loss, damage or expense that Tenant may sustain or incur solely as a result of the electricity provider to the Building failing to supply Tenant’s required quantity of
electricity, and, except as otherwise expressly set forth in this Lease, such discontinuance or failure shall not in any way affect this Lease or the liability of Tenant hereunder or cause a diminution of Base Rent or Additional Rent and the same
shall not be deemed to be a lessening or diminution of services within the meaning of any law, rule or regulation now or hereafter enacted, promulgated or issued or a Reduction of Services under this Lease. 
  
 (C) Subject to Section 7(a)(v)(B), in the event that the
level of electrical service set forth on Exhibit N is not provided to the Premises, such condition shall be deemed a Reduction of Services. 
  

 42 

 (vi) Landlord shall: (A) maintain the Building in compliance with all Requirements,
provided that Tenant shall not have the right to require Landlord to remedy any non-compliance with Requirements enacted prior to the Commencement Date; (B) provide and maintain the Base Building and Tenant’s Fixtures during the entire Term in
a manner consistent with the operation of a first-class office building in downtown Chicago; (C) maintain the Building finishes in a quality and design consistent with the existing Building design and in a manner consistent with the operation of a
first-class office building in downtown Chicago; (D) make available to Tenant and Tenant’s Contractor for their review, at times reasonably acceptable to Landlord and upon reasonable notice to Landlord, Landlord’s working drawings and
specifications of the Building; (E) maintain the landscaping on the Land to be consistent with a first-class office building in downtown Chicago, but in no event in less of a condition or less of a quality than the condition and quality existing as
of the Commencement Date; (F) cause the Building and common areas, including adjacent walkways (whether or not part of the Real Property) to be maintained in first-class condition and reasonably free from debris, snow, and ice consistent with the
operation of a first-class office building in the downtown Chicago; and (G) prohibit smoking in the common areas of the Building; 
  
 (vii) Unless otherwise specified herein Tenant shall, for any extra or additional services provided by Landlord or its agents, pay in
accordance with the Landlord’s current rates therefor. All charges for such extra or additional services shall be due and payable at the same time as the installment of Rent with which they are billed. Any such billings for extra or additional
services shall include an itemization of the extra or additional services rendered, and the charge for each such service. Landlord’s rates for certain extra or additional services will be made known to Tenant at its request on or before each
January 1 during the Term hereof; provided, however, that on the Commencement Date such rates shall be equal to those charged to Building tenants in calendar year 1998 and at no time shall be more than the Most Favored Tenant Rate. Such schedule
shall be subject to change during the Term on ten (10) days’ notice as a result of any increase in Landlord’s Actual Costs provided that such increase shall not apply retroactively to any service which has begun or been contracted for by
Tenant. Notwithstanding anything to the contrary contained in this Subsection 7(a) (vii), Landlord shall provide after-hours HVAC Services to Tenant provided Tenant shall give Landlord thirty (30) minutes advance notice of its need for such
extra or additional HVAC Services and shall pay in accordance with the methodology set forth on Exhibit Y (but in no event higher than the Most Favored Tenant Rate) for such services. If Tenant requires continuous 24-hour HVAC Services
for any portion of the Premises, Landlord will provide such service to Tenant upon written request without the need for daily notice and shall charge Tenant in accordance with the methodology set forth on Exhibit Y (but in no event
higher than the Most Favored Tenant Rate) for such service. In the event Tenant installs its own supplemental air 

  

 43 

 
conditioning units, Tenant may request and Landlord shall provide chilled water, provided that in no event shall Landlord be required to reduce the current
consumption by any tenant of the Building on the date of this Lease in order to provide Tenant chilled water. Subject to the foregoing, Tenant shall be entitled to its pro rata share of the chilled water and, subject to the needs of other tenants,
Landlord will provide additional chilled water as required by Tenant. Chilled water supplied to Tenant shall be at no direct cost to Tenant, however, the cost of providing chilled water to Building tenants shall be included in Expenses. If
Tenant’s needs for additional chilled water require any modification to the Building Systems, Landlord shall not be required to provide such additional chilled water until Tenant and Landlord have agreed upon the actual costs that will be
incurred by Landlord (for which Landlord will be reimbursed by Tenant) in connection with the completion of such modification. In no event will Tenant be charged a hook-up fee. If Landlord fails to supply Tenant’s allocable share of chilled
water to the Premises or to any Critical Area as required above, then such conditions shall be deemed a Reduction of Services. 
  
 If Tenant fails to pay for any extra or additional services within the time period required hereunder after being properly invoiced by Landlord, then
Landlord may, in addition to other remedies available to it hereunder, cease the provision of such extra or additional services, and in no event shall the cessation of such services be deemed to be a lessening or diminution of services within the
meaning of any law or regulation now or hereafter enacted, promulgated or issued or a Reduction of Services for such extra or additional services. Upon proper payment by Tenant, Landlord shall resume providing such extra or additional services.

  
 (viii) Safety and security for the entire
Real Property to protect the safety and possessions of Tenant’s employees, guests, invitees and such other persons as may enter upon the Real Property, it being acknowledged by Landlord that the safety of Tenant, and its employees, guests and
invitees and the security of Tenant ‘s businesses is of paramount importance. In furtherance thereof, each day Landlord shall provide a minimum of twenty-four (24) security attendants on site in the Main Lobby and elsewhere in the common areas
monitoring ingress and egress to and from the Real Property and activities in the common areas of the Building in a manner consistent with other first-class office buildings in downtown Chicago. If Landlord can reasonably demonstrate that a
reduction in the number of security attendants does not materially impair the safety of the Real Property and/or persons entering thereon, Landlord may reduce the number of security attendants required pursuant to this Section. If Tenant determines
that Landlord has not adequately demonstrated that a proposed reduction of security attendants will not materially impair the safety of the Real Property and/or persons entering thereon, and Landlord and Tenant are unable to come to agreement on
such issue within thirty (30) days after the date 

  

 44 

 
that Tenant provides Landlord with notice of its determination, then such matter shall be resolved by Arbitration (with no reduction in the number of
security attendants being made until such Arbitration is concluded). In addition, Landlord shall provide security equipment and personnel to monitor and secure the Loading Docks and freight elevator areas in a manner consistent with other
first-class office building located in downtown Chicago. In addition, either Landlord or the operator of the Garage shall provide surveillance for the Garage in accordance with that provided by other first-class garages in downtown Chicago, provided
if the surveillance in other first-class garages changes during the term of any operating agreement or lease for the Garage, the surveillance for the Garage shall not have to be changed until the end of such operating agreement or lease. Nothing in
this Subsection 7(a)(viii) is intended to increase Landlord’s liability for injury to persons or property occurring in the Garage beyond that otherwise expressly set forth in this Lease. 
  
 (ix) Loading Docks and adjacent areas in common with
Landlord and other tenants, daily from 7:00 a.m. to 6:00 p.m., Saturdays, Sundays and Holidays excepted. Tenant shall have the right to use the Loading Docks at other times and on Saturdays, Sundays and Holidays in accordance with Landlord’s
Actual Costs for such usage, provided Tenant shall give Landlord at least four (4) hours prior notice of such need for the Loading Docks on Saturday, Sunday and Holidays, though Landlord agrees to use reasonable efforts, if necessary, to accommodate
Tenant upon shorter notice. Notwithstanding the foregoing, during the Term, Tenant shall have the sole and exclusive use of the Tenant’s Loading Dock twenty-four (24) hours a day, seven days per week (including Holidays), without prior notice,
but otherwise on the terms set forth herein. 
  
 (x) Tenant shall have the right at any time during the Term, at no charge or expense to Landlord (except that the guard provided by Landlord to monitor the Building’s Proprietary Card Access System shall also monitor the lobby console
connected to Tenant’s security system), upon written request of Tenant, to integrate Tenant’s security system with the Building’s Proprietary Card Access System (which is part of the Building Security System) in accordance with
Exhibit X. In such case, Tenant may purchase the hardware and software for the Premises’ system and its installation from either Landlord, Landlord’s vendor or, if compatible, another vendor. If from Landlord, the purchase
price of any equipment will not exceed one hundred fifteen percent (115%) of Landlord’s Actual Cost unless no other vendor is able to supply such hardware and/or software, in which case the purchase price shall be Landlord’s Actual Cost.
Also at Tenant’s option, Tenant may enter into a maintenance agreement for such system with any third party capable of providing such maintenance or may request Landlord to maintain the system. In the latter case, Landlord shall provide
maintenance to Tenant in accordance with the maintenance contract for the Building’s Proprietary Card Access System at an amount not to exceed one 

  

 45 

 
hundred fifteen percent (115%) of Landlord’s Actual Cost, unless no other third party is capable of maintaining such system, in which event Tenant shall
pay Landlord’s Actual Cost. The installation and maintenance of such system shall be subject to the provisions of this Lease governing alterations to the Premises and standards for Tenant’s self-maintenance. If Tenant does not connect the
card access system for the Premises to the Building’s Proprietary Card Access System, then Tenant, working in conjunction with Landlord, may install a stand alone card access system for the Premises, and if Landlord installs any security device
at the Building’s entrances, the elevators or any other area necessary for ingress to and egress from the Premises, Tenant shall be permitted, at its cost and expense, to install its own device next to or in the vicinity of each of
Landlord’s devices. In addition, Tenant, at its sole election, shall have the right to use the fire stairs within the Premises on a regular basis, subject to compliance with Requirements and the Rules and Regulations. 
  
 (xi) Reasonable access to the Garage and the Premises
twenty-four (24) hours per day, every day; and 
  
 (xii) Use of the Garage in accordance with Section 43; and 
  
 (xiii) Use of the Indiana Room, to the extent Landlord permits such use by other tenants of the Building on a non-exclusive basis, at the Most Favored Tenant Rate, unless Landlord elects to lease the Indiana Room on
an exclusive basis to one or more third parties. 
  
 (b) Landlord
shall also (i) provide use of the Base Building telephone lines (including Tenant’s proportionate share on any partial floor Tenant Occupies) and the right to hook up at the terminal block on each floor, (ii) at Tenant’s request, purchase
and install, light bulbs, ballasts and starters to be paid for by Tenant at an amount not to exceed one hundred fifteen percent (115%) of Landlord’s Actual Cost, unless no other vendor is able to supply such bulbs, ballasts and starters, in
which case Tenant shall pay Landlord’s Actual Cost, and (iii) at Landlord’s option, provide additional services reasonably requested by Tenant and paid for by Tenant in accordance with Section 7(a) (vii), provided that Tenant shall
have the right to independently purchase all bulbs, lamps and ballasts for use in the Premises. In addition, Tenant shall have the right, at its sole option, to contract with other telecommunications and electronic data transmission providers and,
if necessary, Landlord shall make available to such providers the use of the Building risers, core and other areas reasonably required to connect Tenant with such service provider. The performance of the work to cause such connection shall be
subject to the provisions of the Lease governing alterations or to the provisions of the Workletter if such work is performed in connection with the addition of space to the Premises. Furthermore, within thirty (30) days after the Commencement Date,
Tenant shall, at Tenant’s sole cost and expense, separate the phone lines servicing the Premises from those servicing any other parts of the Building. 
  
 (c) Notwithstanding anything in this Section 7 to the contrary: 
  

 46 

 Tenant agrees that, except as otherwise set forth in this Lease, Landlord and its beneficiaries and their
agents shall not be liable in damages, or otherwise, for failure to furnish or delay in furnishing any service when such failure or delay is occasioned, in whole or in part, as a result of any Requirement, or by any Force Majeure; Landlord reserves
the right to stop any service provided for under this Lease, when necessary, by reason of accident or emergency, or for repairs or replacements to Building Systems and services necessary to maintain the Building as a first class office building,
provided that Landlord shall use good faith efforts to conduct such activities to minimize any disruption or inconvenience to Tenant and shall only conduct such repairs or replacements during Business Hours when it is not commercially reasonable for
Landlord to perform such activities after Business Hours. Tenant shall promptly notify Landlord if any service shall be stopped, whereupon Landlord will proceed diligently to restore such service as soon as reasonably possible. Notwithstanding the
foregoing, provided that no Material Default by Tenant is ongoing, in the event that any such failure or delay renders any portion of the Premises Untenantable for a period of at least three (3) consecutive Business Days after Tenant has provided
notice to Landlord of such Untenantability, then Rent shall abate commencing on the day such notice of such Untenantability has been given for the portion of the Premises affected thereby and for the period of such Untenantability. If any Critical
Area is affected and it results in all or a portion of the Premises being Untenantable (e.g., telephones and/or computer systems are unavailable and Tenant has ceased Occupying all or any portion of the Premises), then for purposes of this Lease,
the affected portion of the Premises, and not merely the Critical Area, shall be considered Untenantable, provided, however, Tenant agrees that Landlord may, at Landlord’s sole cost and expense, cure such Untenantability by relocating the
Critical Area, including any equipment located in the Critical Area, to a different location within the Premises or such other space in the Building as Landlord and Tenant may reasonably and mutually agree and connecting the necessary wiring and/or
cabling for the operations on the Critical Area to be relocated. Provided that no Material Default by Tenant is ongoing, if twenty-five percent (25%) or more of the Premises is Untenantable for more than one hundred fifty (150) days in any one
hundred ninety (190) day period, then, upon thirty (30) days prior written notice to Landlord, Tenant shall have the right to terminate this Lease, at Tenant’s sole option, for either the portion of the Premises affected or for the entire
Premises. Notwithstanding anything else contained herein to the contrary, this Section 7(c) shall not be applicable (x) in the event of damage or destruction to the Premises or the Building that is covered by the terms and provisions of Section 15
hereof, or (y) in the event of a condemnation of the Premises, the Building or the Project which is covered by the terms and provisions of Section 16 hereof. 
  
 (d) Tenant agrees to cooperate fully, at all times, with Landlord in abiding by all Requirements and all Rules and
Regulations for the proper functioning and protection of all utilities and services reasonably necessary for the operation of the Premises and the Building. 
  
 (e) Except as otherwise restricted (including, without limitation, as set forth in Section 12), Landlord, throughout the Term of this Lease, shall
have reasonable access to any and all Base Building mechanical installations located in the Premises or electrical closets contained in the Premises. Except as otherwise expressly permitted herein, Tenant further agrees that neither Tenant, nor its
servants, employees, agents, visitors, licensees, or 

  

 47 

 
contractors shall at any time tamper with, adjust, or otherwise in any manner affect Landlord’s mechanical installations, without Landlord’s prior
written consent, which consent shall not be unreasonably withheld or delayed, provided that Landlord may impose conditions to how Tenant affects such mechanical installations as Landlord deems appropriate in its sole discretion. 
  
 8. Condition and Care of Premises. 
  
 (a) Except as otherwise set forth herein, (i) no promises of the Landlord to
alter, remodel, improve, repair, decorate, or clean the Premises or any part thereof have been made, and (ii) no representation respecting the condition of the Premises, the Building, or the Land, has been made to Tenant by or on behalf of Landlord
(except to the extent otherwise set forth herein or in the Workletter); provided, however, Landlord agrees it will maintain and repair the Building to the extent such repairs are required and shall maintain, repair or replace, in a manner consistent
with first-class office buildings in downtown Chicago, any fixtures, appurtenances or equipment necessary or proper to maintain the Building and the Building Systems, Tenant’s Fixtures, common areas (including, without limitation, the Building
Plaza) and appurtenances, Land, structural components of the Building, elevator lobbies and bathrooms on each floor of the Premises (consistent with elevator lobbies and bathrooms on multi-tenant floors) and Building facade, regardless of whether or
not such items are located within the Premises, provided that Landlord shall not be responsible for defects arising from or repairs and replacements necessitated by work contracted for directly by Tenant or designated by Tenant’s architect.
Landlord shall promptly make any repairs or replacements necessary to satisfy Landlord’s obligations under this Section 8. Furthermore, Landlord shall maintain the Building Plaza, the facade and the Retail Space in a manner consistent
with other first-class office buildings in downtown Chicago. This Lease does not grant any rights to light or air over or about the property of Landlord, provided, however, that, so long as Tenant satisfies the Tenant Leasing Requirement. Landlord
shall not construct on the Land any new structure or improvement which is higher in elevation than the second floor of the Building. 
  
 (b) Except for any damage to the Premises resulting from any act of Landlord or its employees and agents, and subject to the provisions of Section
15 hereof, to the extent not required of Landlord under Section 8(a) above, Tenant shall, at its own expense, keep the Premises in good repair and condition, subject to reasonable wear and tear, and shall promptly and adequately repair
all damage to the Premises caused by Tenant or any of its employees, agents, or invitees, including replacing or repairing all damaged or broken glass (except for exterior windows), fixtures, and appurtenances resulting from any such damage, and
within any reasonable period of time specified by Landlord. If Tenant does not reasonably promptly and adequately comply with the terms of this Section 8(b), Landlord may, but need not, after twenty (20)-days prior written notice to Tenant
make such repairs and replacements and Tenant shall pay Landlord’s Actual Cost. Landlord, however, will make any repairs and replacements, at Tenant’s sole cost and expense at Landlord’s Actual Cost, if Tenant so requests. Tenant
shall take special care to keep all areas of the Premises which are visible by or accessible to the public, such as elevator lobbies and corridors, in good order and appearance consistent with a first-class office building. Nothing in this
Section 8 shall 

  

 48 

 
increase any of Tenant’s obligations with respect to the return of the Premises as set forth in Section 9. Upon twenty-four (24) hours prior
written notice (except in the case of an emergency, when no prior notice shall be required) to Tenant, Landlord may, but shall not be required to, enter the Premises (other than any Tenant Secure Area) at all reasonable times to make such necessary
repairs, alterations, improvements and additions, including ducts and all other facilities for air conditioning service as Landlord shall reasonably deem necessary, to the premises or to the Building or to any equipment located in the Building or as
Landlord may be required to do by the City of Chicago or by order or decree of any court or by any other governmental authority. Except in the case of an emergency. Landlord may not enter any Tenant Secure Area without Tenant’s prior written
approval, which approval may be withheld in Tenant’s sole discretion, and, if such approval is granted, Landlord shall be accompanied by a representative of Tenant at all times while in a Tenant’s Secure Area. If the work described in this
subsection cannot be performed during Business Hours without materially disrupting the conduct of Tenant’s business in the affected portion of the Premises, such work shall be performed after-hours at no cost to Tenant. If the work can be
performed during Business Hours without materially disrupting the conduct of Tenant’s business but Tenant requests that the work be done after-hours, Tenant shall pay the additional costs incurred by Landlord in performing such after-hours
work. Landlord shall be permitted to take onto the Premises and, to the extent reasonably necessary, to store in an area adjacent to the area in which the work is being performed all materials that may be required in connection with the work being
performed under this subsection; provided, however, Landlord shall in no event materially interfere with the conduct of Tenant’s business in the Premises. 
  

(c) Landlord hereby accepts and approves the layout of the Premises and the location and configuration of the Tenant’s Property as it exists on
the Commencement Date. 
  
 9. Return of Premises.

  
 (a) At the termination of this Lease by lapse of time or
otherwise or upon termination of Tenant’s right of possession without terminating this Lease, Tenant shall surrender possession of the Premises to Landlord and deliver all keys to the Premises to Landlord and make known to the Landlord the
combination of all locks of vaults Tenant elects to leave in the Premises. At the time Tenant surrenders the Premises, except as otherwise required by Landlord with respect to a Structural Alteration as set forth in Section 6 hereof, Tenant shall
have no obligation to remove Tenant’s Property or any other property of Tenant in the Building but outside of the Premises or to repair or restore the Premises or other area of the Building, except as otherwise expressly set forth in Section
9(b), but shall not intentionally commit waste to the Premises. 
  
 (b) Subject to the terms hereof, Tenant may remove any item of Tenant’s Property (other than Tenant’s Fixtures and Tenant Improvements) or other property of Tenant in the Building but outside the Premises upon Tenant’s
vacation of the Premises. Tenant shall, within thirty (30) days after Landlord’s written request, repair any damage to the Premises (other than the paint, carpeting or wall coverings) or other areas of the Building caused by the 

  

 49 

 
removal of Tenant’s Property. Tenant shall not (i) intentionally commit waste to the Premises or (ii) cause a condition resulting in a violation of the
building code or other applicable Requirements, provided Tenant shall have no obligation to correct any such violations which are necessary to permit the Premises to be occupied. Except as otherwise set forth herein, in no event shall Tenant be
required to remove any improvements at the end of the Term, including, without limitation, staircases, vaults, raised computer floors, wiring, cabling or Antennae. All of Tenant’s Property remaining in the Premises or other property of Tenant
remaining in the Building after Tenant vacates the entire Premises shall become Landlord’s property and Tenant shall be deemed to have conveyed title to such property to Landlord as if by bill of sale. Landlord shall in no event be responsible
for the value, accounting, preservation or safekeeping of such property. Landlord’s inventory of abandoned or stored property shall be final, conclusive and incontestable. If Tenant fails to remove any Tenant’s Property that Tenant is
required under Section 6 to remove within thirty (30) days after receipt of written notice from Landlord, and Landlord thereafter removes and stores such Tenant’s Property, Tenant shall pay Landlord, within twenty (20) days of demand,
any and all reasonable expenses incurred by Landlord in such removal and storage plus fifteen percent (15%) of such expenses incurred. 
  
 10. Holding Over. Should Tenant continue in possession of the Premises after the end of the Term, such holding over shall be construed to be a
tenancy from month to month only, and such monthly tenancy shall be subject to the covenants, conditions, Rules and Regulations contained or referred to in this Lease. Such tenancy may be terminated by thirty (30) days prior written notice given by
either party to the other. Tenant’s rent obligations for any period of holding over shall be as follows: 
  
 (a) For the first thirty (30) days that Tenant shall hold over after the expiration of the Term (the “First Holdover Period”), subject to
Section 10(d) below, Tenant shall be obligated to pay rent at a monthly rental rate equal to one hundred twenty-five percent (125%) of the Base Rent and Additional Rent due from Tenant for the last month of the Term (“First Holdover
Rent”). 
  
 (b) For the second thirty (30) days that
Tenant shall hold over after the expiration of the Term (the “Second Holdover Period”), subject to Section 10(d) below, Tenant shall be obligated to pay rent at a monthly rental rate equal to one hundred fifty percent (150%)
of the Base Rent and Additional Rent due from Tenant for the last month of the Term (“Second Holdover Rent”). 
  
 (c) Beginning on the first (1st) day after the Second Holdover Period and continuing for so long as Tenant retains possession of all or a portion of the
Premises (the “Final Holdover Period”), subject to Section 10(d) below, Tenant shall be obligated to pay rent at a monthly rental rate equal to two hundred percent (200%) of the Base Rent and Additional Rent due from Tenant
for the last month of the Term (“Final Holdover Rent”). 
  
 (d) Notwithstanding anything in this Section 10 to the contrary, to the extent Tenant is holding over with respect to 75,000 Rentable Square Feet of the Premises or less, 

  

 50 

 
both Base Rent and Additional Rent shall be calculated during the Holdover Period solely on the number of Rentable Square Feet for which Tenant continues to
retain possession. If Tenant is holding over with respect to greater than 75,000 Rentable Square Feet of the Premises, both Base Rent and Additional Rent shall be calculated on the entire number of Rentable Square Feet in the Premises on the last
day of the Term. 
  
 (e) Landlord and Tenant agree and acknowledge
that the rent payable by Tenant for holding over during the First Holdover Period shall represent liquidated damages for such holding over, and shall be deemed a fair and equitable measure of damages for Tenant’s holding over. Beginning on the
first (1st) day of the Second Holdover Period, Tenant shall also be responsible for any Actual Damages incurred by Landlord as a direct result of Tenant’s holding over. In no event shall Tenant ever be responsible for consequential damages.
Nothing contained in this Section 10 shall be deemed to limit Landlord’s rights to commence and prosecute proceedings to obtain possession of the Premises, including forcible entry and detainer proceedings. 
  
 (f) Notwithstanding the provisions of this Section 10 set forth above,
if an event of Force Majeure shall occur prior to the end of the First Holdover Period or the Second Holdover Period which prevents Tenant from vacating the Premises and Landlord from moving a new tenant into the Building, the First Holdover Period
or the Second Holdover Period, as applicable (and Tenant’s obligation to pay First Holdover Rent or Second Holdover Rent, as applicable, thereunder), shall be extended by a number of days equal to the number of days that the event of Force
Majeure shall continue, but in no event shall either the First Holdover Period or the Second Holdover Period be extended by more than sixty (60) days. 
  
 11. Rules and Regulations. Tenant agrees to observe the rights reserved to Landlord contained in Section 12 hereof and agrees, for itself,
its employees, agents, clients, customers, invitees and guests, to comply with the Rules and Regulations set forth in Exhibit P and such other reasonable Rules and Regulations adopted by Landlord (“Rules and
Regulations”). Tenant’s prior written consent, which shall not be unreasonably withheld or delayed, shall be required for any new regulation which will materially or adversely affect Tenant’s use and enjoyment of the Premises.
Landlord shall give Tenant at least thirty (30) days notice of any new Rules and Regulations. Landlord shall use commercially reasonable efforts to enforce the Rules and Regulations against the other tenants in the Building and shall not otherwise
discriminate against Tenant in the enforcement of such Rules and Regulations. Except for the exercise of commercially reasonable efforts with respect to the enforcement of the Rules and Regulations, nothing contained in this Lease shall be construed
to impose upon Landlord any duty or obligation to enforce the terms, covenants and conditions of any other lease against any other tenant or any other persons, and Landlord and its beneficiary shall not be liable to Tenant for violation of the same
by any other tenant, its employees, agents, invitees, or by any other person. In the event of a conflict between the terms of the main Sections of this Lease and the terms of the Rules and Regulations, the terms of the main Sections of this Lease
shall control. 
  

 51 

 12. Rights Reserved to Landlord. Landlord, in addition to any other rights set forth herein,
reserves the following rights, exercisable without notice and without liability to Tenant for damage or injury to property, person or business and without effecting an eviction, constructive or actual, or disturbance of Tenant’s use or
possession or giving rise to any claim for setoff or abatement of Rent or affecting any of Tenant’s obligations under this Lease: 
  
 (a) Subject to Section 36, to change the street address of the Building, provided, however, that Landlord’s right to change the street address
of the Building shall be conditioned upon Landlord paying any and all reasonable costs associated with any such address change, including, without limitation, the cost of new stationery, new signage and any other changes to comply with Requirements.

  
 (b) To retain at all times, and to use in appropriate
instances, pass keys to the Premises, except that Landlord shall not have keys for, nor shall it enter, any Tenant’s Secure Area without Tenant’s prior consent, which consent may be withheld in Tenant’s sole discretion, unless,
because of an emergency, Landlord is unable to obtain such consent and must have access to such areas. If Tenant re-keys all or any portion of the Premises, such re-keying shall continue to fall within Tenant’s current master-key system.

  
 (c) Subject to Section 5, to grant to anyone the right
to conduct any business or render any service in the Building, whether or not it is the same as or similar to the use expressly permitted to Tenant by Section 3; provided such business or service is consistent with the operation of a
first-class office building in downtown Chicago. 
  
 (d) To
exhibit the Premises during the last twelve (12) months of the Term at reasonable hours upon reasonable notice, provided Landlord shall place no signs on the Premises. 
  
 (e) To enter the Premises at reasonable hours upon reasonable advance notice (except in the case of an emergency) for
inspection and supplying janitor service or other services to be provided to Tenant hereunder, provided that, except in the event of an emergency, upon reasonable advance request from Tenant, Landlord shall, at no expense to Tenant, enter the
Premises at a reasonably alternative time, including after Business Hours, if Landlord’s proposed entry into the Premises would materially interfere with Tenant’s use of the Premises. If such entry would not materially interfere with
Tenant’s use of the Premises but Tenant requests that such entry be made after Business Hours, Tenant shall pay any additional costs incurred by Landlord as a result of such after-hours entry. 
  
 (f) To restrict access to the Building and implement certain security
procedures after Business Hours, which may include requiring all persons entering or leaving the Building during such hours as Landlord may from time to time reasonably determine to identify themselves to watchmen by registration or otherwise, and
to establish their right to enter or leave in accordance with the provisions of applicable Rules and Regulations adopted by Landlord. Except as a result of its negligence or wilful misconduct, Landlord shall not be 

  

 52 

 
liable to Tenant (or any subtenant) in damages for any error with respect to admission to or eviction or exclusion from the Building of any person. In case
of fire, invasion, insurrection, mob, riot, civil disorder, public excitement or other commotion, or threat thereof, Landlord reserves the right to limit or prevent access to the Building during the continuance of the same, shut down elevator
service, activate elevator emergency controls, or otherwise take such action or preventive measures deemed reasonably necessary by Landlord for the safety of the tenants or other occupants of the Building or the protection of the Building and the
property in the Building. Landlord and Tenant each agrees to cooperate, and coordinate with each other with respect to any reasonable safety program developed by the other, provided that such cooperation and coordination shall be at no cost or
expense to the cooperating party. 
  
 (g) To reasonably regulate
access to common areas and to prevent access to the non-general public areas pursuant to the provisions of applicable Rules and Regulations. 
  
 (h) To run wires, conduits and similar items in existence on the date of this Lease through the core areas of the Premises or the electrical closets
contained therein. 
  
 (i) Except as otherwise set forth in this
Lease, Landlord reserves the right to relocate, enlarge, reduce or change exits or entrances in or to the Building and to decorate and to make, at its own expense, repairs, alterations, additions and improvements, structural or otherwise, in or to
the Building or any part thereof, and any adjacent building, land, street or alley, including for the purpose of connection with or entrance into or use of the Building; provided, however, Landlord shall maintain the first-class image of the
Building. Landlord may for such purposes temporarily erect scaffolding and other structures reasonably required by the character of the work to be performed, and during such operations may enter upon the Premises (other than any Tenant Secure Area),
with reasonable prior notice (as set forth in Section 12(e)), and take into and upon or through any part of the Building, including, to the extent reasonably necessary, the Premises, all materials that may be required to make such repairs,
alterations, improvements, or additions, and in that connection Landlord may temporarily close some (but not all) public entry ways, other public spaces, stairways or corridors and, except as otherwise set forth herein, interrupt or temporarily
suspend any services or facilities agreed to be furnished by Landlord, provided that if, as a result of such activities, the Premises, or any portion thereof, becomes Untenantable, Tenant shall have such rights as are provided in Section
7(c). Except to the extent such activities materially interfere with Tenant’s use of the Premises, Landlord may at its option make any repairs, alterations, improvements and additions in and about the Building and the Premises during
Business Hours, and if Tenant desires to have such work performed during other than Business Hours, Tenant shall pay Landlord’s Actual Cost (including any reasonable overtime expenses for the employees of Manager) resulting therefrom. To the
extent such activities materially interfere with Tenant’s use of the Premises, such activities shall be performed after Business Hours at Landlord’s sole cost and expense. Notwithstanding anything to the contrary contained in this
Section 12(i) Landlord agrees that it will neither (i) change the number of passenger elevators or elevator cabs servicing the Premises, or increase the number of floors serviced by such elevators (provided that Landlord may permit up to four
(4) passenger elevators (8 cabs) that service the Premises to stop at the second floor of the Building, provided that the initial capital 

  

 53 

 
charges required to permit such stops shall be at Landlord’s sole cost and expense and shall not be included in Expenses, but the costs of continued
operation of the elevators stopping at such floors shall be included in Expenses), nor (ii) modify or add to the current floor arrangement for elevator banks A and B nor make one of the floors Occupied by Tenant, other than the 20th floor, a
transfer floor. 
  
 (j) Any entry into the Premises by Landlord or
its agents in compliance with the terms and provisions of this Lease shall not constitute an eviction of Tenant in whole or in part nor cause any abatement of the Rent (other than as may be provided herein) or render Landlord or its agents liable
solely by reason of such entry. 
  
 13. Assignment and
Subletting. 
  
 (a) Except as otherwise provided herein,
Tenant shall not, without the prior written consent of Landlord in each instance, (i) 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 (provided mechanic liens shall not be a default hereunder as long as Tenant is complying with the terms of this Lease and as long as
no transfer of Tenant’s interest under this Lease occurs as a result of such liens), (iii) convey or assign this Lease or any of Tenant’s rights hereunder, (iv) sublet the Premises or any part thereof, or (v) permit the use and occupancy
of the Premises or any part thereof for any purpose not provided for under Section 3 of this Lease or by anyone other than the Tenant and Tenant’s employees; provided that in the case of the matters described in clauses (iii) and (iv) above,
Landlord’s consent may not be unreasonably withheld or delayed. 
  
 (b) Notwithstanding anything to the contrary contained in this Lease but subject to Subsection 13(j), provided Tenant is not in Material Default, Tenant shall, without the prior written consent of Landlord, have the right to enter
into subleases for all or any part of the Premises and grant to such subtenants such rights as Tenant may have under the terms of this Lease with respect to parking, use of the Roof (so long as any subtenant using a portion of the Roof pays Landlord
the current market rent being charged by Landlord therefor), and, for subtenants subleasing at least two (2) full floors, renewal. Tenant shall provide Landlord with notice and copies of all subleases entered into by Tenant. 
  
 (c) Notwithstanding the foregoing, in the event that Tenant wishes to enter
into a sublease (other than with an Affiliate) which would cause the aggregate portion of the Premises being sublet by Tenant (pursuant to the proposed sublease and all other subleases then in effect) to equal or exceed two (2) full floors, then
Tenant shall give Landlord prior written notice of such proposed sublease stating either (i) that Landlord may, by written notice to Tenant delivered within ten (10) Business Days after receipt of Tenant’s notice with respect to the proposed
sublease, elect to recapture that portion (“Recapture Portion”) of the Premises to be included in the proposed sublease, effective as of the date that such proposed sublease would have become effective or (ii) that, in the case of a
sublet for less than four (4) years, Tenant, prior to the end of the Term, intends to reoccupy the portion (“Temporary Sublet 

  

 54 

 
Premises”) of the Premises to be included in the proposed sublease and such reoccupancy will be for a period of at least twenty-four (24) months
and, therefore, Landlord may not recapture such portion of the Premises. 
  
 If Tenant delivers the notice under (i) above, and Landlord notifies Tenant of its intent to recapture within the aforesaid ten (10) Business Days, this Lease shall terminate with respect to the Recapture Portion as
of the effective date of such recapture by Landlord, and Landlord and Tenant shall promptly enter into an amendment to this Lease to reflect such recapture of the Recapture Portion by Landlord (including the effective date thereof) and to amend such
other terms and provisions of the Lease which are affected thereby, including, but not limited to, a pro-rata reduction of Base Rent, Tenant’s Proportionate Share for Expenses and Tenant’s Proportionate Share for Taxes. If Landlord fails
to notify Tenant of its intent to recapture within the aforesaid ten (10) Business Days, Landlord shall be deemed to have elected not to recapture the Recapture Portion. If Landlord does not elect to recapture the Recapture Portion as set forth
above, Tenant may thereafter enter into the proposed sublease and Tenant shall pay to Landlord a share of the Net Sublease Proceeds in accordance with Section 13(d). 
  
 (d) If Tenant delivers a notice under (c)(i) above and Landlord does not exercise its right of recapture or under (c)(ii)
above, Landlord shall be entitled to receive fifty percent (50%) of the Net Sublease Proceeds. Except to the extent Tenant is entitled to retain Net Sublease Proceeds, Net Sublease Proceeds shall be deemed to be Additional Rent and shall be paid to
Landlord on the first day of each month during the term of any such sublease. As used herein: 
  
 (i) “Net Sublease Proceeds” shall mean Sublease Proceeds less Permitted Expenses. For purposes of determining the Net Sublease Proceeds, the Permitted Expenses shall be deducted as and when paid by Tenant
and the Net Sublease Proceeds shall be deemed received as and when paid by such assignee or subtenant, provided that Tenant shall be entitled to be reimbursed for all Permitted Expenses before Net Sublease Proceeds are determined. 
  
 (ii) “Permitted Expenses” shall mean the aggregate of (1) broker
commissions and legal fees incurred by Tenant in connection with any such sublease of Temporary Sublet Premises, (2) the actual out-of-pocket cost of leasehold improvements installed by Tenant at its expense to make the Temporary Sublet Premises
suitable for occupancy by the subtenant, including the cost of constructing demising walls, corridors and separating mechanical systems, and (3) any advertising expenses or financial concessions, rent concessions or credits granted by Tenant.

  
 (iii) “Rent Per Square Foot” shall mean the sum of
the Base Rent and Additional Rent divided by the number of Rentable Square Feet comprising the Premises at the time such calculation is made. 
  

 55 

 (iv) “Sublease Proceeds” shall mean the product of (x) the Sublease Rent per Square Foot less
the Rent Per Square Foot, multiplied by (y) the number of Rentable Square Feet constituting the sublet portion of the Premises. 
  
 (v) “Sublease Rent” shall mean any rent or other consideration paid to Tenant, directly or indirectly, by any subtenant or any other amount
received by Tenant from or in connection with any subletting. 
  
 (vi) “Sublease Rent per Square Foot” shall mean the Sublease Rent divided by the Rentable Square Feet of space demised under a sublease. 
  
 Net Sublease Proceeds, Sublease Proceeds and/or Sublease Rent shall be recalculated from time to time to reflect any correction in the prior calculation
thereof due to (x) subsequent payments received by Tenant, (y) the final adjustment of payments to be made to or by Tenant or (z) mistake discovered within one (1) year of the error. Promptly upon the receipt of any such payment, the making of any
such adjustment or the discovery of any such mistake, Tenant shall submit to Landlord a recalculation of the Net Sublease Proceeds, Sublease Proceeds and/or Sublease Rent, and an adjustment shall be made between Landlord and Tenant, if applicable
with respect thereto on account of prior payments made pursuant to this Section 13(d). 
  
 (e) If Tenant has procured an assignee, Tenant shall, by written notice to Landlord, given not less than thirty (30) days prior to the proposed effective date of such assignment, advise Landlord of its intention from,
on and after a stated date to assign this Lease to such proposed assignee, and, Tenant’s notice given pursuant to this Subsection 13(e) shall include (1) the name and address of the proposed assignee, (2) sufficient information to permit
Landlord to determine the nature and character of the business of the proposed assignee and (3) such other information as Landlord shall reasonably request that is readily available to Tenant (excluding financial information of such assignee, except
to the extent required in connection with Section 13(h)). 
  
 (f) In the event Tenant enters into a sublease for a portion of the Premises that is in excess of one full floor of the Building with an entity that is not an Affiliate of Tenant, Landlord agrees that, provided such sublease grants Landlord
the right, in a manner satisfactory to Landlord in its sole discretion, to substitute space and relocate such subtenant upon the termination of this Lease or Tenant’s right to possession under this Lease, it shall, within thirty (30) days after
Tenant’s request, enter into a Non-Disturbance and Attornment Agreement (Sub-Tenant) substantially similar to the form of agreement attached hereto as Exhibit Q. Tenant shall provide Landlord with such information as Landlord may
reasonably request with respect to a proposed subtenant requesting a Non-Disturbance and Attornment Agreement. 
  
 (g) For the purposes of this Section 13, any merger, consolidation, reorganization or other similar corporate, partnership or limited liability
company transaction of Tenant or any change of control of Tenant shall not be deemed to constitute an assignment 

  

 56 

 
of this Lease and shall not require the Landlord’s consent. Notwithstanding anything in this Section 13 to the contrary, Tenant may, without the
prior consent of Landlord, assign this Lease to an Affiliate of Tenant. 
  
 (h) No such assignment, subletting, occupancy or use, whether with or without Landlord’s prior consent, nor any such collection or application of Rent or fee for use and occupancy, shall be deemed a waiver by Landlord of any term,
covenant or condition of this Lease or, except as required under Section 13(b), the acceptance by Landlord of such assignee, subtenant, occupant or user as tenant hereunder. The consent by Landlord of any assignment shall not relieve Tenant
from its obligation to obtain the express prior consent of Landlord to any further assignment in accordance with and to the extent required under the terms of this Lease. Except as expressly provided in this Section 13(h), neither any
assignment of Tenant’s interest in this Lease nor any subletting, occupancy or use of the Premises or any part thereof by any person other than Tenant, nor any collection of Rent by Landlord from any person shall, in any circumstances, relieve
Tenant of its obligations under this Lease on Tenant’s part to be observed and performed and, other than as set forth below, each assignment of this Lease shall be conditioned upon confirmation from Tenant of its continuing primary liability
under 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. Any such assignee shall execute and deliver to Landlord upon demand an instrument confirming such assumption. Notwithstanding anything to the contrary contained in this Section 13, in the event Tenant assigns this
Lease, Tenant may request in writing that the Landlord consent to the release of the assignor Tenant from all liability arising under this Lease from and after the date of the assignment. Such request shall be accompanied by current financial
statements for the assignee and a written agreement executed by the assignee assuming all of the obligations of Tenant from and after the assignment date. Tenant shall promptly provide Landlord with such additional information concerning the
assignee as Landlord may reasonably request. Within fifteen (15) days after receipt of all information and documents required to be delivered to the Landlord with respect to the assignee, Landlord shall notify Tenant of whether Landlord consents to
the release of the assignor Tenant, which consent may be withheld in Landlord’s sole discretion; provided, however if the request for release of the assignor tenant is accompanied by evidence establishing to Landlord’s
satisfaction that the assignee Tenant after the transfer has a Consolidated Shareholder’s Equity that is equal to or greater than the greater of (x) two billion dollars ($2,000,000,000) and (y) Tenant’s Consolidated Shareholder’s
Equity on the date immediately prior to the assignment, then Landlord may not unreasonably withhold its consent to the release of the assignor Tenant. 
  
 (i) Notwithstanding anything to the contrary contained in this Section 13, Tenant may not mortgage, pledge, hypothecate or encumber its leasehold
interest in the Premises (“Leasehold Mortgage”) without obtaining Landlord’s prior written approval. Landlord agrees to give the holder of a Leasehold Mortgage approved by Landlord, by registered or certified mail, copies of
all notices of default served upon Tenant by Landlord, provided that prior to such notice Landlord has been notified in writing of the address of such Leasehold Mortgage holder. Landlord agrees that if Tenant has failed to cure such default 

  

 57 

 
within the applicable grace period, then the holder of the Leasehold Mortgage shall have an additional thirty (30) days within which to cure or correct such
default; provided, however, that such additional thirty (30) day period shall not apply in the case of a default which can be cured by the payment of money. Any such holder shall be subject to all of the terms, provisions and covenants of this
Lease. Any such holder shall agree to give to Landlord notice of any default by Tenant under any such Leasehold Mortgage. 
  
 (j) Notwithstanding anything to the contrary contained in this Section 13, Tenant shall be permitted to enter into a sublease with any then current
tenant of the Building, unless Landlord reasonably determines that Landlord can, within a time frame acceptable to the proposed subtenant, provide space reasonably acceptable to or suitable for the proposed subtenant. Landlord shall notify Tenant of
whether it has made such determination within five (5) days after receipt of written inquiry from Tenant. 
  
 14. Waiver of Certain Claims; Indemnification Provisions. 
  

(a) Subject to Section 21(a) and the last sentence of this Subsection 14(a), to the extent not expressly prohibited by any Requirements
and except with respect to matters which are damaged by perils that are required to be insured as set forth in Section 21 hereof, Tenant releases Landlord Indemnitees from and waives all claims for damages to property or for the interruption
of Tenant’s business sustained by the Tenant resulting directly or indirectly from fire or other casualty, cause, or any existing or future condition, defect, matter, or thing in or about the Premises, the Building or any part of it, or from
any equipment or appurtenance therein, or from any accident in or about the Building, or from any act or neglect of any tenant or other occupant of the Building or any part thereof or of any other person. The foregoing release shall not operate as a
release of Landlord from liability for any negligent act or wilful misconduct of the Landlord Indemnitees. This Section 14 shall apply especially, but not exclusively, to damage caused by water, snow, frost, steam, excessive heat or cold,
sewerage, gas, odors, or noise, or the bursting or leaking of pipes or plumbing fixtures, broken glass, sprinkling or air conditioning devices or equipment, or flooding of basements, or from any other thing or circumstance, whether of a like nature
or of a wholly different nature. Subject to the last sentence of this Subsection 14(a), all personal property belonging to the Tenant or any occupant of the Premises that is in the Building, the Garage or the Premises shall be there at the
risk of the Tenant or other person only and, except to the extent arising out of Landlord’s negligence or wilful misconduct, Landlord shall not be liable for damage thereto or theft or misappropriation thereof. Notwithstanding the foregoing,
with respect to any damage to Tenant’s Property which is caused by the act or neglect of Landlord Indemnitees, Landlord shall reimburse Tenant for the reasonable cost of repairing such damage. 
  
 (b) Subject to Section 21(a), to the extent not expressly prohibited
by any Requirements and except with respect to matters which are damaged by perils that are required to be insured as set forth in Section 21 hereof, Landlord releases Tenant Indemnitees from and waives all claims for damages to property or
for any loss of rents sustained by Landlord 

  

 58 

 
resulting directly or indirectly from fire or other casualty, cause or any existing or future condition, defect, matter or thing in or about the Premises,
the Building or any part of it, or from any equipment or appurtenance therein, or from any accident in or about the Building, or from any act or neglect of any Tenant Indemnitee or other person. The foregoing release shall not operate as a release
of Tenant from liability for any negligence or wilful misconduct of the Tenant Indemnitees. 
  
 (c) To the extent not expressly prohibited by any Requirements, Tenant agrees to hold the Landlord Indemnitees, harmless and to indemnify each of them from and against all third party claims of whatever nature against
the Landlord Indemnitees arising from any act, omission or negligence of any Tenant Indemnitees, and their licensees, invitees or visitors occurring anywhere within or about, or in connection with, the Building or surrounding property, where such
accident, injury or damage results from an act, omission or negligence of Tenant Indemnitees or their licensees, invitees or visitors, except to the extent arising out of any negligence or wilful misconduct of such Landlord Indemnitees. This
indemnity and hold harmless agreement shall include indemnity from and against any and all liability, fines, suits, demands, costs and expenses of any kind or nature (including, without limitation, reasonable attorneys’ fees and disbursements)
incurred in or in connection with any such third party claim or proceeding brought thereon, and the defense thereof. In the event Landlord makes a claim upon Tenant under this Section 14(c) and such claim was unfounded or resulted from the
negligence or wilful misconduct of any Landlord Indemnitee, then Landlord shall indemnify and hold harmless the Tenant for any expenses incurred by Tenant as a result of such claim. 
  
 (d) To the extent not expressly prohibited by any Requirements, Landlord agrees to hold Tenant Indemnitees, harmless and to
indemnify each of them from and against all third party claims of whatever nature against the Tenant Indemnitees arising from any act, omission or negligence of any Landlord Indemnitees, and their licensees, invitees or visitors occurring anywhere
within or about, or in connection with, the Building or surrounding property, where such accident, injury or damage results from an act, omission or negligence of Tenant Indemnitees or their licensees, invitees or visitors, except to the extent
arising out of any negligence or wilful misconduct of such Tenant Indemnitees. This indemnity and hold harmless agreement shall include indemnity from and against any and all liability, fines, suits, demands, costs and expenses of any kind or nature
(including, without limitation, reasonable attorneys’ fees and disbursements) incurred in or in connection with any such third party claim or proceeding brought thereon, and the defense thereof. In the event Tenant makes a claim upon Landlord
under this Section 14(d) and such claim was unfounded or resulted from the negligence or wilful misconduct of any Tenant Indemnitee, then Tenant shall indemnify and hold harmless the Landlord for any expenses incurred by Landlord as a result
of such claim. 
  
 15. Damage or Destruction by Casualty.

  
 (a) If the Premises or any part of the Building shall be
damaged by fire or other casualty (“Casualty Damage”), then, except as set forth below, Landlord shall proceed to repair and restore the same (other than the Tenant’s Property) to its prior existing condition with reasonable
promptness, subject to reasonable delays for insurance adjustments and delays 

  

 59 

 
caused by Force Majeure and Requirements then in effect. Landlord shall, with reasonable promptness after the occurrence of such Casualty Damage direct an
Approved Architect to estimate the length of time that will be required to substantially complete the repair and restoration of the Casualty Damage including the restoration of the Base Building and Tenant’s Property and shall by notice advise
Tenant of such estimate, which estimate shall be given no later than sixty (60) days after such occurrence. If the Casualty Damage is to (1) twenty-five percent (25%) or more of the Premises, (2) prohibits all reasonable means of access to at least
twenty-five percent (25%) of the Premises or (3) is to any portion of a Critical Area and renders at least twenty-five percent (25%) of the Premises Untenantable (e.g., telephones and/or computer systems are unavailable and Tenant has ceased
Occupying the affected portion of the Premises) and it is so estimated that the amount of time required to substantially complete the repair and restoration of (i) the Base Building portion of the entire Premises will exceed two hundred seventy
(270) days or (ii) the Base Building and Tenant’s Property for the entire Premises will exceed three hundred sixty (360) days, both calculated from the earlier to occur of (x) the date Landlord receives insurance proceeds for restoration of the
Base Building or (y) the date that is ninety (90) days after the date of such fire or casualty, then, in either case, each of Landlord and Tenant shall have the right to terminate this Lease as of the date of such Casualty Damage upon giving notice
to the other at any time within forty-five (45) days after Landlord gives Tenant the notice containing said estimate; provided that Landlord may only terminate this Lease if Landlord is also terminating all other leases directly affected by such
casualty. Landlord shall have no liability to Tenant and Tenant shall not be entitled to terminate this Lease if such Landlord’s repairs and restoration are not in fact completed within the time period estimated by the Approved Architect for
the repairs and restoration other than the Tenant’s Property, as aforesaid, or within said two hundred seventy (270) days, provided that Tenant shall be entitled to terminate this Lease (but Landlord shall not be liable for any damages) if such
repairs and restoration are not completed within ninety (90) days (plus an additional ninety (90) days for Force Majeure) after the estimated time period or such 270-day period, whichever is longer, so long as Landlord shall proceed with reasonable
promptness and due diligence. Notwithstanding anything to the contrary herein set forth, (i) if any Casualty Damage requiring, in the Approved Architect’s reasonable estimate, more than one hundred eighty (180) days to repair both the Base
Building portion of the Building and the Tenant’s Property occurs during the last twenty-four (24) months of the Term, then each of Landlord and Tenant shall have the option to terminate such affected portion of the Premises as of the date of
the Casualty Damage by written notice to the other within forty-five (45) days after the date Landlord delivers its estimate of the time required to repair and (ii) if more than twenty-five percent (25%) of the Premises is so damaged or unavailable
(as described above) or any Critical Area is so damaged or unavailable (as described above) such that at least twenty-five percent (25%) of the Premises is rendered Untenantable, then each of Landlord and Tenant shall have the option to terminate
this Lease as of the date of the Casualty Damage by written notice to the other within such 45-day period. Landlord shall have no duty pursuant to this Section 15 to repair or restore any portion of the Tenant’s Property. 
  
 (b) In the event any such Casualty Damage (1) is to twenty-five percent (25%)
or more of the Premises, (2) prohibits all reasonable means of access to at least twenty-five percent (25%) of the Premises or (3) is to any portion of a Critical Area and renders at least 

  

 60 

 
twenty-five percent (25%) of the Premises Untenantable and if the Lease is not terminated pursuant to the foregoing provisions of this Section 15, then Rent
for that portion of the Premises in which Tenant cannot conduct normal operations shall abate during the period beginning with the date of such Casualty Damage and ending, with respect to each portion of the Premises, on the earlier to occur of
Tenant’s commencement of normal operations on such portion of the Premise or one hundred twenty (120) days after the date when Landlord, to the extent required under this Section 15, substantially completes the repair and restoration
work of the Casualty Damage, provided that if Tenant’s repair or restoration of the Tenant’s Property is delayed by reason of Force Majeure or Requirements, then such 120-day period after which Tenant’s shall be obligated to resume
paying Rent shall be extended one day for each day Tenant’s repair or restoration is so delayed; subject to a maximum extension of ninety (90) days. Such abatement shall be in an amount bearing the same ratio to the total amount of Rent for
such period as the Rentable Square Footage of that portion of the Premises in which Tenant cannot conduct normal operations bears to the Rentable Square Footage of the entire Premises. Subject to all applicable Requirements, upon the request of
Tenant, Landlord agrees that Landlord will use reasonable efforts (and shall cause its contractors to use reasonable efforts) to allow Tenant to promptly commence the restoration of the Tenant’s Property as soon as possible on a floor-by-floor
basis, regardless of whether or not Landlord has substantially completed the repair or restoration of such portion of the Premises, provided that such commencement will not interfere with Landlord’s completion of its restoration work. In the
event of termination of this Lease pursuant to this Section 15, Rent shall be apportioned on a per diem basis and be paid to the date of such fire or other casualty. If the Untenantability results from Casualty Damage to a Critical Area,
Tenant agrees that Landlord may, at Landlord’s sole cost and expense, cure such Untenantability by relocating the Critical Area, including any equipment located in the Critical Area, to a different location within the Premises or such other
space in the Building as Landlord and Tenant may reasonably and mutually agree and connecting the necessary wiring and/or cabling for the operations in the Critical Area to be relocated. 
  
 (c) In the event that neither Landlord nor Tenant has terminated the Lease pursuant to Subsection 15(a), Landlord
shall proceed to repair and restore the portions of the Casualty Damage other than the Tenant’s Property in accordance with Subsection 15(a), and Tenant shall repair and restore to a safe condition in compliance with all Requirements
such portion of the Tenant’s Property that Tenant deems prudent or necessary to restore. 
  
 16. Eminent Domain. 
  
 (a) If all or any portion of the Premises shall be permanently taken or condemned by any competent authority for any public or quasi-public use or purpose, the Term with respect to the affected portion of the Premises 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 such taking, and without apportionment of the award to or for the benefit of Tenant (except as specifically
set forth below). If such taking affects all or a substantial portion of the Building, or any part thereof which includes at least twenty-five percent (25%) of the Premises or any Critical Area that renders at least twenty-five percent 

  

 61 

 
(25%) of the Premises Untenantable (e.g., telephones and/or computer systems are unavailable and Tenant has ceased Occupying the affected portion of the
Premises), or if any portion of the Building which would prevent all reasonable means of access to at least twenty-five percent of the Premises, shall be taken or condemned by any competent authority for any public or quasi-public use or purpose,
then each of Landlord and Tenant shall have the option of terminating this Lease as of the effective date of such taking by written notice to Landlord, such notice of termination to be delivered within sixty (60) days after the effective date of
such taking. If the Untenantability results from a taking of a Critical Area, Tenant agrees that Landlord may, at Landlord’s sole cost and expense, cure such Untenantability by relocating the Critical Area, including any equipment located in
the Critical Area, to a different location within the Premises or such other space in the Building as Landlord and Tenant may reasonably and mutually agree and connecting the necessary wiring and/or cabling for operations in the Critical Area to be
relocated. Current Rent shall be apportioned as of the date of such termination. 
  
 (b) If this Lease is for any reason not terminated pursuant to Subsection 16(a), Landlord shall as soon as possible restore the Building to a condition as close as possible to its prior condition, subject to
delays caused by Force Majeure and also subject to zoning laws, building codes and other Requirements applicable thereto then in effect, using the award received by Landlord (but not in excess thereof); in such event this Lease shall continue in
force at the square foot rental rates and adjustments herein provided for the Premises applied to the Rentable Square Feet of the Premises existing in the Building as restored, but Rent shall abate for the affected portion of the Premises as to the
periods when the Premises or portion thereof is Untenantable as a result of such taking and work of restoration. 
  
 (c) In the event of any such taking, Landlord shall be entitled to receive the entire award for such taking, provided that Landlord shall not be entitled
to make or receive any award for Tenant’s Property. Tenant shall have no claim against Landlord or the condemning authority for the value of any expired portion of the Term and Tenant hereby expressly assigns to Landlord all of its rights in
and to any such award. Nothing contained herein shall be deemed to prevent Tenant from making a separate claim in any condemnation proceedings for business interruption, damage to Tenant’s Property and any moving or relocation expenses;
provided, however, such claim shall not in any way reduce the amount of the award that Landlord would otherwise receive pursuant to this Section 16(c). 
  

17. Default; Landlord’s Rights and Remedies. 
  
 (a) The occurrence of any one or more of the following constitutes a “Default” by Tenant under this Lease: 
  
 (i) Failure by Tenant to pay any Rent or installment thereof
when due and the continuance of such failure for ten (10) Business Days after written notice thereof from Landlord to Tenant (provided that interest shall begin to accrue on the unpaid sum at the Default Rate beginning on the first day after the
date due); 
  

 62 

 (ii) Failure by Tenant to pay any money due to Landlord hereunder (other than Rent) when
due and the continuance of such failure for twenty (20) Business Days after written notice thereof from Landlord to Tenant (provided that interest shall begin to accrue on the unpaid sum at the Default Rate beginning on the first day after the date
due); 
  
 (iii) Failure by Tenant to observe or
perform any other covenant, agreement, condition or provision of this Lease and the continuance of such failure for thirty (30) days after notice thereof from Landlord to Tenant; provided, however, that if such failure cannot reasonably be cured
within thirty (30) days and if Tenant commences such cure within such thirty (30) days, then such period shall be extended for so long as Tenant is prosecuting such cure with diligence and continuity, provided that Tenant shall not be entitled to an
extension of this cure period if the default is of a nature that it is incapable of being cured. Notwithstanding the foregoing, in no event shall Tenant be entitled to any additional notice or cure period if Tenant fails to affect a cure under
Section 30 within the time periods set forth therein. 
  
 (iv) 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; 
  
 (v) A trustee or receiver is appointed for Tenant or for the major part of its property and is not discharged within sixty (60) days after such appointment; and/or 
  
 (vi) All or a material portion of Tenant’s assets are levied upon under execution or attached by
process of law and the proceedings are not dismissed within sixty (60) days; and/or 
  
 (vii) Tenant abandons the entire Premises; and/or 
  
 (viii) Bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings, or other proceedings
for relief under any bankruptcy law, or similar law for the relief of debtors, are instituted by or against Tenant and, if instituted against Tenant, are allowed against it or are consented to by it or are not dismissed within ninety (90) days after
such institution. 
  
 (b) Upon the occurrence of any Default,
Landlord shall, to the extent permitted by law, 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, but shall be in addition to, any other
right or remedy allowed it by law or by other provisions of this Lease: 
  

 63 

 (i) Landlord, by notice to Tenant given on the occurrence or during the continuance of
such Default, 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, on the date stated in such notice (which shall be no earlier than 10 days after the giving
thereof); 
  
 (ii) Landlord, by notice to Tenant
given on the occurrence or during the continuance of such Default, may terminate the right of Tenant to possession of the Premises without terminating this Lease, in which event the right of Tenant to possession of the Premises or any part thereof
shall cease on the date stated in such notice (which shall be no earlier than 10 days after the giving thereof); and/or 
  
 (iii) Landlord shall enforce the provisions of this Lease pursuant to the terms of Section 40 of this Lease. 
  
 (c) If Landlord exercises either the remedies provided for in Subsections
(i) or (ii) of the foregoing Section 17(b), Tenant shall surrender possession and vacate the Premises immediately and deliver possession thereof to Landlord, and Tenant hereby grants Landlord full and free license to enter into and
upon the Premises in such event and take peaceful possession of the Premises, with due process of law, and Landlord may, by legal means, remove all occupants and property therefrom 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 operation of law. 
  
 (d) If Landlord, pursuant to the provisions of Section 17(b)(ii) hereof, terminates the right of Tenant to possession of the Premises without
terminating this Lease, such termination of possession shall not release Tenant, in whole or in part, from Tenant’s obligation to pay the Rent hereunder for the full Term. Landlord shall have the right, from time to
time, to recover from Tenant, and Tenant shall remain liable for, all Rent and any other 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 exercise reasonable efforts to mitigate damages to the extent required under Illinois law, but this obligation shall not require Landlord to divert any prospective tenants from any other portion of 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 reasonably necessary or desirable and in connection therewith change the locks to the
Premises and Tenant shall, upon demand, pay the cost thereof together with Landlord’s expenses of reletting (including leasing commissions and reasonable attorneys fees) provided that all such expenses shall be equitably prorated if the term of
the new lease extends beyond the scheduled expiration of this Lease. Landlord may collect the rents from any such reletting and apply the same first to the payment of the expenses of reentry, redecoration, repair and alterations and the expenses of
reletting (including, without limitation, leasing commissions and reasonable attorneys fees) 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 

  

 64 

 
against the amount of Rent 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 a credit on its indebtedness to Landlord 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 or repossession, repairs, alterations and 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 be 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) In the event of the termination of this Lease by Landlord as provided for by Subsection (i) of Section
17(b), Landlord shall be entitled to recover from Tenant all the 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 court costs and reasonable attorneys’ fees incurred by Landlord in the
enforcement of its rights and remedies hereunder, and in addition Landlord shall be entitled to recover as damages for loss of the bargain and not as a penalty (x) the aggregate sum which at the time of such termination represents the excess, if
any, of the present value of the Rent (including any Rent or portion thereof for which Tenant has otherwise received a credit or abatement) for the remainder of the Term pursuant to the applicable provisions of Sections 1 and 2, over the then
present value of the then aggregate fair rental value of the Premises for the balance of the Term, such present worth to be computed in each case on the basis of a per annum discount equal to the Prime Rate in effect from the respective dates upon
which such rentals would have been payable hereunder had this Lease not been terminated and (y) any damages in addition thereto, including reasonable attorneys’ fees and court costs, which Landlord shall have sustained by reason of the breach
of any of the covenants of this Lease other than for the payment of Rent. 
  
 (f) All property removed from the Premises by Landlord pursuant to any provision of this Lease or of law may, at Landlord’s option, be 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 storage charges against such property so long as the same shall be in Landlord’s
possession or under Landlord’s control. If the Lease or Tenant’s right of possession is terminated prior to the Expiration Date, then all property not removed from the Premises or not retaken from storage by Tenant within sixty (60) days
after the earlier of (i) Tenant ceasing operations at the Property and (ii) a final unappealable determination by a court or arbitrator of competent jurisdiction that the Lease or Tenant’s right of possession has been terminated shall be
conclusively deemed to have been conveyed by Tenant to Landlord as by 

  

 65 

 
bill of sale without further payment or credit by Landlord to Tenant, unless and to the extent Landlord elects in writing not to accept title to any such
property. 
  
 (g) If any action for breach of or to enforce any
provision of this Lease is commenced by Landlord against Tenant, the court in such action shall award to the party in whose favor judgment is entered, a reasonable sum as attorneys’ fees, which attorneys’ fees shall be paid by the losing
party in such action. Tenant shall pay all of Landlord’s costs, charges, and expenses, including court costs and reasonable attorneys’ fees, incurred by Landlord in any litigation in which Tenant causes Landlord, without Landlord’s
fault, to become involved or concerned. 
  
 (h) In the event that
Tenant shall file for protection under any Chapter of the Bankruptcy Code now or hereafter in effect, Landlord and Tenant agree, to the extent permitted by all Requirements, to request that the debtor-in-possession or trustee-in-bankruptcy, if one
is appointed, assume or reject this Lease within sixty (60) days thereafter. 
  
 18. Default by Landlord; Tenant’s Remedies; Self-Help. 
  
 (a) The occurrence of any of the following events shall constitute a “Landlord Default” under this Lease by Landlord: 
  
 (i) Landlord fails at the time when due to make payments or
credit any sums to be paid or credited under this Lease by Landlord to or for the benefit of Tenant, or fails to reimburse Tenant for Self-Help Repairs and such failure continues for twenty (20) Business Days after written notice thereof to Landlord
(a “Monetary Landlord Default”) (provided that interest shall begin to accrue on the unpaid or uncredited sum at the Default Rate beginning on the first day after the date due); or 
  
 (ii) Landlord fails to perform or observe any other covenant
or condition to be performed or complied with by Landlord under this Lease, and such failure continues for thirty (30) days after written notice thereof to Landlord, provided that if such failure cannot reasonably be cured within thirty (30) days,
then such period shall be extended for so long as Landlord is prosecuting such cure with diligence and continuity, provided that Landlord shall not be entitled to an extension of the cure period if the default is of a nature that is incapable of
being cured. 
  
 (b) In the event of a Landlord Default or other
failure which entitles Tenant to invoke its self-help rights under this Lease, Tenant shall have all of the other rights and/or remedies granted to Tenant under any other provisions of this Lease, as well as such other remedies as may now or
hereafter exist at law or in equity. 
  

 66 

 (c) Tenant shall have the right to offset any expenses incurred in exercising its self-help rights, as
permitted under this Lease, against Rent and any other charges, fees, payments or reimbursements due from Tenant to Landlord. 
  
 (d) Tenant’s self-help rights and other remedies set forth in this Lease may be exercised at the option of Tenant, and are expressly intended as
alternatives to, and not a substitute for, Tenant’s rights and remedies at law or in equity or as set forth in this Section 18. 
  
 (e) Provided the terms of this Lease expressly permit Tenant to remedy a failure by Landlord in the case of an emergency, then, upon twenty-four (24)
hours prior notice (telephonic or oral) to Building management, Tenant may remedy such failure, unless within such twenty-four (24) hour period Landlord has begun taking action to remedy such failure and continues proceeding diligently with respect
thereto. Landlord shall reimburse the actual out-of-pocket reasonable cost thereof within thirty (30) days following Tenant’s delivery of: (i) a written notice describing in reasonable detail the action taken by the Tenant; (ii) reasonably
satisfactory evidence of the cost of such remedy; and (iii) such sworn contractor’s statements, waivers of lien and other applicable documentation as are reasonably necessary to protect Landlord’s title to the Building. All work performed
by Tenant pursuant to this Section 18(e) shall be deemed to be an Alteration. 
  
 (f) Provided that no Material Default by Tenant is ongoing, Tenant may elect the following remedies in the event of a Reduction of Services that is not otherwise subject to Section 18(e): 
  
 (i) If the Reduction of Services has occurred and is ongoing
(A) pursuant to Sections 7(a)(i)(B) or 7(a)(iv) either (1) for a period of at least five (5) consecutive Business Days or (2) for at least twelve (12) separate Business Days during any twelve (12) consecutive month period, or (B) pursuant to
Sections 7(a)(ii)(B), 7(a)(v)(C) or 7(a)(vii) either (1) for two (2) consecutive Business Days or (2) for at least six (6) Business Days in any twelve (12) consecutive month period then any of the parties designated to receive notices for Tenant
pursuant to this Lease may give written notice (the “Service Notice”) to Landlord substantially in the form attached hereto as Exhibit R: (1) describing the Reduction of Services, (2) providing a detailed explanation
and reasonable evidence thereof, and (3) identifying the representative(s) of Tenant (the “Service Representative(s)”) with the requisite authority and expertise who will work with Landlord to correct the Reduction of Services.

  
 (ii) Upon Landlord’s receipt of the
Service Notice, Landlord and Tenant’s Service Representative(s) shall work together diligently and in good faith to identify and resolve the cause of the Reduction of Services within (A) with respect to a Reduction of Services pursuant to
Sections 7(a)(i)(B) or 7(a)(iv), the thirty (30) days following Landlord’s receipt of the Service Notice or (B) with respect to a Reduction of Services pursuant to Sections 7(a)(ii)(B), 

  

 67 

 
7(a)(v)(C) or 7(a)(vii), the three (3) Business Days following Landlord’s receipt of the Service Notice (in each case, the “Initial Cure
Period”). The Initial Cure Period shall be extended to the extent necessary to resolve the cause of the Reduction of Services, provided that (Y) Landlord has commenced and is thereafter diligently pursuing such cure, and (Z) the Initial
Cure Period shall not be extended by more than sixty (60) additional days with respect to Section 18(f)(ii)(A) or five (5) Business Days with respect to Section 18(f)(ii)(B). 
  
 (iii) If, after the end of the Initial Cure Period, the Reduction of Services has not been cured so as to
comply with the terms and provisions of this Lease, then Tenant may deliver a second written notice (the “Self-Help Repair Notice”) substantially in the form attached hereto as Exhibit S to Landlord containing (A) a
statement that within five (5) Business Days after Landlord’s receipt of the Self-Help Repair Notice, Tenant intends to commence its own repairs, (B) a reasonable description of the procedures and repairs that Tenant intends to undertake on the
Real Property and the proposed cost thereof (the “Self-Help Repairs”) and (C) the names of the parties Tenant intends to use to perform the Self-Help Repairs. 
  
 (iv) If, prior to Tenant’s commencement of repairs, as set forth in the Self-Help Repair Notice,
Landlord commences the Self-Help Repairs, then Tenant shall not undertake the Self-Help Repairs, provided that Landlord diligently pursues the Self-Help Repairs to completion. 
  
 (v) If Landlord does not commence the Self-Help Repairs within the five (5) Business Day period set forth in
Section l8(f)(iii)(A) and diligently pursue the Self-Help Repairs to completion, then Tenant may commence and complete said Self-Help Repairs, in which event, the Self-Help Repairs shall be performed in accordance with the applicable
provisions of Section 6 of this Lease, except that Landlord’s prior approval shall not be required, and Tenant shall pursue such Self-Help Repairs diligently to completion. 
  
 (vi) In the event Tenant commences and completes the Self-Help Repairs, Landlord shall reimburse Tenant for
Tenant’s Actual Cost thereof (but in no event in excess of the cost set forth in the Self-Help Repair Notice plus ten percent (10%)), within thirty (30) days following Tenant’s delivery to Landlord of: (A) a written notice describing in
reasonable detail the action taken by Tenant, (B) reasonably satisfactory evidence of the cost of the Self-Help Repairs, and (C) sworn contractors’ statements, waivers of lien (or equivalent documentation) and other applicable documentation
reasonably necessary to protect Landlord’s title to the Building. 
  
 (g) Notwithstanding anything else contained herein to the contrary, this Section 18 shall not be applicable (i) in the event of damage or destruction to the Premises or the Building 

  

 68 

 
which is covered by the terms and provisions of Section 15 of this Lease or (ii) in the event of a condemnation of the Premises, the Building or the
Project which is covered by the terms and provisions of Section 16 of this Lease. Determination of whether Tenant has acted reasonably in exercising its rights under this Section 18 shall be subject to Arbitration. 
  
 Whenever Tenant shall deliver a notice to Landlord pursuant to this
Section 18, Tenant shall deliver a copy of such notice to a first Mortgagee, provided that Landlord has provided Tenant with current names and addresses for such first Mortgagee. 
  
 19. Subordination and Attornment. 
  
 (a) Landlord has heretofore and may hereafter from time to time execute and deliver a Mortgage. Subject to Section 19(c), if
requested by Landlord, Tenant will either (i) subordinate its interest in this Lease to any Mortgage (except to the extent that the first Mortgagee shall prohibit Tenant from subordinating to any subordinate Mortgages), and to any and all advances
thereunder and to the interest thereon, and all renewals, replacements, amendments, modifications, and extensions thereof, or (ii) make Tenant’s interest in this Lease or certain of Tenant’s rights hereunder superior thereto; and Tenant
will promptly execute and deliver such agreement or agreements as may be reasonably required by Landlord or the holder of such Mortgage. 
  
 (b) It is further agreed that if the interests of Landlord under this Lease are transferred by reason of, or assigned in lieu of, foreclosure or other
proceeding for enforcement of any Mortgage, or if any Superior Lease is terminated, or if the holder of any Mortgage or any ground lessor acquires a lease in substitution therefor, then Tenant under this Lease will, if the holder of any such
Mortgage or any purchaser or assignee, as the case may be, or ground lessor shall so elect in writing in its sole discretion, either (i) attorn to it and will perform for its benefit all the terms, covenants and conditions of this Lease on
Tenant’s part to be performed with the same force and effect as if it were Landlord originally named in this Lease, or (ii) enter into a new lease with it for the remaining Term of this Lease and otherwise on the same terms and conditions and
with the same options, if any, then remaining. The provisions of the second sentence of paragraph (a) above and of clause (i) of this Section 19(b) shall inure to the benefit of such holder of such Mortgage, purchaser or assignee or ground
lessor and shall be self-operative unless the option in (ii) of either paragraph (a) above or this paragraph (b) is exercised, and no further instrument shall be required to give effect to such clause, and no further instrument shall be required to
give effect to said provisions. Tenant, however, upon demand of any such holder of such Mortgage, purchaser, or assignee or ground lessor, agrees to enter into a written agreement containing provisions consistent with the relevant foregoing
provisions of this Section 19, satisfactory to any such holder of such Mortgage, purchaser, or assignee or ground lessor acknowledging such attornment and setting forth the terms and conditions of its tenancy. 
  
 (c) Anything in this Section 19 notwithstanding, Tenant’s
obligation to subordinate this Lease as provided in this Section shall be contingent upon Tenant receiving a 

  

 69 

 
subordination, nondisturbance and attornment agreement in substantially the form attached hereto and made a part hereof as Exhibit T
(“Nondisturbance Agreement”) from the Mortgagee. Landlord also agrees to obtain a Nondisturbance Agreement from the current Mortgagee prior to the execution of this Lease by Tenant. 
  
 20. Time is of the Essence. Time is of the essence of this Lease and
each of its provisions; provided, however, that wherever under the terms and provisions of this Lease the time for payment or performance falls upon a Saturday, Sunday or Holiday, such time for payment or performance shall be extended to the next
Business Day. 
  
 21. Subrogation and Insurance.

  
 (a) Anything in this Lease to the contrary
notwithstanding, Landlord and Tenant each waives all rights of recovery, claim, action, or cause of action against the other, its agents (including partners, both general and limited), trustees, officers, directors and employees, for (i) any loss or
damage that may occur to the Premises or the Real Property or any personal property of such party therein, by reason or any peril required to be insured against under this Lease (and whether or not actually insured) by the waiving party, or (ii)
business interruption and losses (and any other consequential losses) occasioned thereby sustained by such party as a result of the damage to the Premises or Real Property, regardless of cause or origin, including negligence of the other party.
Tenant and Landlord covenant that, to the fullest extent permitted by all Requirements, no insurer shall hold any right of subrogation against the other. Landlord and Tenant shall advise their respective insurers of the foregoing and such waiver
shall be permitted under any policies maintained by Landlord and Tenant pursuant to the terms of this Lease. 
  
 (b) Notwithstanding anything in this Lease to the contrary, so long as the Tenant is Amoco Corporation or one of its Affiliates, Tenant may, subject to
the terms of this Section 21(b), fulfill its insurance obligations under this Lease through its alternative risk management programs, including self-insurance and Landlord hereby consents thereto. If Tenant elects to self-insure, upon
Landlord’s written request, Tenant shall provide Landlord with a letter of self-insurance. Tenant shall not be allowed to self-insure under this Lease for any portion of the Term during which Tenant’s Net Worth (including, without
limitation, the aggregate Net Worth of those Affiliated with Tenant) is less than Two Hundred Million and No/l00ths Dollars ($200,000,000.00). In the event, however, Tenant’s Consolidated Shareholder’s Equity is less than or equal to
$200,000,000, then until Landlord receives satisfactory evidence that such condition no longer exists Tenant shall carry (i) “all risk” property damage insurance on a replacement cost basis covering the Tenant’s Property and (ii)
commercial general liability insurance (including contractual liability insuring the indemnification provisions contained in this Lease), in an amount not less than $10,000,000.00, in any combination of primary and excess liability coverage as
Tenant may select, subject to a deductible that shall not exceed $100,000.00 insuring Tenant, Landlord, Manager, Landlord’s agents and beneficiaries and any partners, directly or indirectly of such party, all such policies to be with terms,
coverages, and issued by companies that are commercially reasonable in Tenant’s industry. As a condition of allowing Tenant to self- 

  

 70 

 
insure and/or utilize a deductible and/or self-insured retention. Tenant agrees to provide a legal defense for Landlord and its agents in the same manner as
if insurance had been provided and Landlord and its agents were named as additional insureds. 
  
 (c) To the extent Tenant is not self-insured as provided in Subsection 21(b) above, Tenant shall, prior to the commencement of the Term and thereafter during the Term, furnish to Landlord certificates issued by
the respective carriers evidencing such coverage or replacements and renewals thereof, which policies or certificates shall state that such insurance coverage may not be canceled without at least thirty (30) days’ prior written notice to
Landlord and Tenant. 
  
 (d) Landlord shall at all times during
the Term comply with and cause the Real Property to comply with all applicable Requirements (including, without limitation, the Americans with Disabilities Act); provided, however, that Tenant shall not require Landlord to remedy any non-compliance
with Requirements enacted on or prior to the Commencement Date. Landlord shall indemnify Tenant against any loss, cost, claim, damage or expense suffered or incurred by Tenant to the extent arising out of any non-compliance by Landlord of this
obligation (including reasonable attorneys fees). 
  
 (e) At all
times during the Term Landlord shall carry (i) “all risk” property damage insurance on a one hundred percent (100%) replacement cost basis covering the Building, excluding Tenant’s Property and (ii) commercial general liability
insurance (including contractual liability insuring the indemnification provisions contained in this Lease) naming Tenant as an additional insured, in an amount not less than the greater of (X) $50,000,000.00 or (Y) such other amount that is
commercially reasonably available to owners of comparable first-class office buildings, in any combination of primary and excess liability coverage as Landlord may select, provided that the insurance required under clauses (i) and (ii) above may be
subject to a deductible that shall not exceed $100,000.00 or such greater deductible as permitted by the Mortgagee and (iii) rent loss insurance (including a reasonable deductible) insuring Landlord and any partners, directly or indirectly of such
party, all such policies to be with terms, coverages, and issued by companies that are commercially reasonable for owners of first-class office buildings in downtown Chicago. Landlord shall, prior to the commencement of the Term and thereafter
during the Term, furnish to Tenant certificates issued by the respective carriers evidencing such coverage or replacements and renewals thereof, which policies or certificates shall state that such insurance coverage may not be canceled without at
least thirty (30) days’ prior written notice to Landlord and Tenant. 
  
 22. Nonwaiver. Except to the extent specifically provided herein, no waiver of any condition expressed in this Lease shall be implied by any neglect of either party 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 only for the time and in the manner specifically
stated. Without limiting the provisions of Section 10, it is agreed that no receipt of moneys 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 of any
notice shall reinstate, continue or extend the 

  

 71 

 
Term or affect any notice given to Tenant prior to the receipt of such moneys. 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 moneys due, and the payment of said moneys shall not waive or affect said notice, suit or judgment. No payment by Tenant or receipt by Landlord of a
lesser amount than any installment or payment of Base Rent or Additional Rent or other amounts due, unless such lesser amount is a result of a credit given by Landlord to Tenant or Tenant’s exercise of the rights to offset specifically provided
for herein, shall be deemed other than a payment on account of the amount due and no endorsement or statement on any check or any transmittal document accompanying any check or payment of any amount due shall be deemed an accord and satisfaction.
Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of any amount due or pursue any other remedies available to Landlord. 
  
 No act or thing done by Landlord or Landlord’s agents during the Term shall be deemed an acceptance of a surrender of
the Premises, and no agreement to accept such surrender shall be valid unless in writing signed by Landlord. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Premises prior to the termination of
this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of this Lease or a surrender of the Premises. In the event Tenant at any time desires to have Landlord sublet the Premises
for Tenant’s account, Landlord or Landlord’s agents are authorized to receive said keys for such purpose without releasing Tenant from any of the obligations under this Lease. 
  
 23. Estoppel Certificate. (a) The Tenant agrees that from time to time (but in no event more than two times within
any twelve-month period) upon not less than thirty (30) days’ prior written request by Landlord or the Mortgagee, which shall be delivered in accordance with Section 26, the Tenant (and/or any permitted assignee, subtenant, licensee,
concessionaire, or other occupant of the Premises claiming by, through, or under Tenant) will deliver to Landlord or to the Mortgagee, a statement in writing signed by Tenant or such other party certifying (i) that this Lease is unmodified and in

provided for in the Lease; (vi) that there are no actions, whether voluntary or otherwise, pending against Tenant under the bankruptcy laws of the United States or any State thereof; (vii) that Tenant is not in default under any provision of this
Lease, or to Tenant’s knowledge, no event that with notice or the passing of time would become a default exists, or, if such an event or default exists, the nature thereof in detail; (viii) that there are no outstanding obligations of Landlord
to construct or perform capital improvements in the Premises, other than as may be specified in such certificate; and (ix) such other matters as may be reasonably required by the Mortgagee (“Estoppel Certificate”). 
  

 72

twelve-month period) upon not less than thirty (30) days’ prior request by Tenant, the Landlord will deliver to Tenant a statement in writing signed by Landlord certifying (i) that this Lease is unmodified and in full force and effect (or if

prepayment of Rent other than that provided for in the Lease; (vi) that there are no actions, whether voluntary or otherwise, pending against Landlord under the bankruptcy laws of the United States or any State thereof; (vii) that Landlord is not in

reasonably required by the Tenant.

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

 (d) The Exhibits and any other clauses, plats and riders endorsed on or
affixed to this Lease are a part hereof. 
  
 (e) Nothing contained
in this Lease shall be deemed or construed by the parties hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer, or any association between Landlord and Tenant, it being expressly understood and
agreed that neither the method of computation of Rent nor any other provisions contained in this Lease nor any act of the parties hereto shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord
and tenant. 
  
 (f) The legal invalidity of any provision of this
Lease shall not impair or affect in any manner the validity, enforceability, or effect of the rest of this Lease. 
  
 (g) All understandings and agreements, oral or written, heretofore made between the parties hereto are merged in this Lease, which alone fully and
completely expresses the agreement between Landlord and Tenant. 
  
 (h) All obligations of Landlord and Tenant hereunder shall survive the expiration of the Term.

 (j) Except to the extent specifically provided otherwise herein, each of
Landlord and Tenant agrees that in any situation where such party’s consent, approval or waiver is required hereunder, it will be reasonable in its determination of whether to grant such consent, approval or waiver. 
  

 75 

 (k) Notwithstanding anything to the contrary contained herein, in any case under this Lease where either
Landlord or Tenant is required to do any act (other than any act relating to the payment of money), failure to perform shall not be deemed a breach hereunder to the extent such failure is due to Force Majeure, and, except as otherwise specifically
set forth in this Lease, the time period to perform such act shall be extended by a time period equal to the duration of the Force Majeure. 
  
 28. Landlord’s Authority and Quiet Enjoyment. Landlord covenants and represents that it has full and complete authority to enter into this
Lease under all of the terms, conditions, and provisions set forth herein, and Landlord further covenants that, subject to the terms, provisions, and conditions hereof, so long as Tenant is not in Default hereunder, Tenant shall, during the Term
hereof, peacefully and quietly enjoy the Premises without hindrance or molestation. 
  
 29. Landlord. The term “Landlord” as used in this Lease means only the owner or owners at the time being of the Building so that in the event of any assignment, conveyance, or sale, once or
successively, of the Building, or any assignment of this Lease by Landlord, said Landlord making such sale, conveyance, or assignment shall be and hereby is entirely freed and relieved of all covenants and obligations of Landlord hereunder accruing
after such sale, conveyance, or assignment, and, except as expressly set forth in the Nondisturbance Agreement, Tenant agrees to look solely to such purchaser, grantee, or assignee with respect thereto, provided such purchaser, grantee or assignee
has assumed Landlord’s obligations hereunder after the date of such transfer. This Lease shall not be affected by any such assignment, conveyance, or sale, and Tenant agrees to attorn to the purchaser, grantee, or assignee. Any liability of
Landlord under this Lease shall be limited solely to the interest of Landlord in the Building, and in no event shall any personal liability be asserted against Landlord or any member or partner thereof in connection with this Lease nor shall any

acts of Tenant and, in case of any such lien attaching to Landlord’s interest in the Real Property, as opposed to Tenant’s leasehold interest, to pay and remove the same within thirty (30) days unless Tenant is in good faith disputing such
lien in which event Tenant shall (i) indemnify Landlord and the first Mortgagee from all loss in connection with such lien, (ii) if requested by the first Mortgagee, either insure over such lien on Landlord’s and/or the first Mortgagee’s
title insurance policy or bond over such lien or otherwise provide, in Landlord’s reasonable judgment, adequate security to Landlord and/or the first Mortgagee and (iii) commence and diligently pursue an action to obtain a release of such lien;
provided, however, in any event, subject to the provisions of this Section 30, Tenant shall obtain a release of such lien if (A) Landlord is in danger of losing title to the Building as reasonably determined by Landlord or, (B) such lien is
in excess of five million dollars ($5,000,000), if 

  

 76 

 
(y) the existence of such lien causes a default under the Mortgage or (z) the existence of such lien will give a purchaser under contract to purchase the
Building the right to terminate such contract. In the event of (y) or (z) above, Landlord shall promptly notify Tenant of the lien giving rise to the default or right to terminate, the time period provided under the applicable document to remove or
otherwise provide assurances with respect to such lien and the name and phone number of the appropriate person with the lender or purchaser for Tenant to contact. After receipt of such notice from Landlord, Tenant shall have the right to negotiate
with such lender or purchaser regarding the actions that Tenant may take with respect to such lien and Landlord agrees to cooperate with Tenant in connection therewith. Tenant acknowledges that 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 the Real Property, and any and all liens and encumbrances created by Tenant shall attach only to
Tenant’s leasehold interest in the Premises. 
  
 31.
Relocation of Tenant. Landlord shall not, without the express written consent of Tenant, substitute for the Premises other premises, which consent may be withheld in Tenant’s sole discretion.

portions of the Building as are necessary in order for Tenant (i) to use, operate and maintain the Translogic vertical mail conveyor system owned by Tenant and located in the Premises, (ii) to run conduits, wires and other like items to and from and
to use, operate, maintain and test the generator owned by Tenant located in the generator room of the Building, (iii) to use the conduits, wires and other like items in existence on the date of this Lease that are used by Tenant in connection with
the Prudential Easement and (iv) to run conduits, wires and other like items through the core areas of the Building, including the core areas contained in other tenants’ premises, to the extent necessary for Tenant’s operations. This
easement shall expire on the expiration or earlier termination of this Lease or Tenant’s right to possession hereunder. In addition to the foregoing, Landlord agrees that Tenant shall have the exclusive right, throughout the Term, to utilize
the Prudential Easement. 
  
 33. WAIVER OF TRIAL BY JURY;
VENUE. IF, FOR ANY REASON, THE PARTIES HERETO MUTUALLY AGREE NOT TO UTILIZE THE PROVISIONS OF SECTION 40 HEREOF OR A DISPUTE IS NOT SUBJECT TO SECTION 40, AS PROVIDED THEREIN, THEN WITH RESPECT TO ANY ACTION BROUGHT IN COURT, THE
FOLLOWING TERMS SHALL APPLY: 
  
 (a) THE RESPECTIVE PARTIES HERETO
SHALL AND THEY HEREBY DO WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER IN CONNECTION WITH ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, ANY
RENT DISPUTE UNDER THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S USE OR OCCUPANCY OF THE PREMISES OR ANY EMERGENCY OR STATUTORY REMEDY. 
  

 77 

 (b) IF EITHER LANDLORD OR TENANT DESIRES TO BRING AN ACTION AGAINST THE OTHER IN CONNECTION WITH THIS
LEASE, SUCH ACTION SHALL BE BROUGHT IN THE FEDERAL OR STATE COURTS LOCATED IN CHICAGO, ILLINOIS. LANDLORD AND TENANT CONSENT TO THE JURISDICTION OF SUCH COURTS AND WAIVE ANY RIGHT TO HAVE SUCH ACTION TRANSFERRED FROM SUCH COURTS ON THE GROUNDS OF
IMPROPER VENUE OR INCONVENIENT FORUM. 
  
 34. No
Representations by Landlord. Landlord, Manager, and Landlord’s agents have made no promise to alter, remodel, decorate, clean or improve the Premises or the Building and no representations, warranties or promises, express or implied with
respect to the condition of the Building, the Real Property, the Premises, the existing fixtures or the Building Systems or as to any other thing or fact related thereto except as herein expressly set forth, and no rights, easements or licenses are
acquired by Tenant by implication or otherwise except as expressly set forth herein. Tenant’s execution of this Lease shall be conclusive evidence as against Tenant that the Premises were in good order and satisfactory condition as of the
Commencement Date. 
  
 35. Successors and Assigns. Except
as otherwise expressly set forth herein, 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 transfer, assignment, mortgage, encumbrance, lien, charge, or subletting contrary to the provisions of Section 13. 
  
 36. Building and Tenant Identity. 
  
 (a) So long as Landlord has not terminated Tenant’s possession of the Premises or terminated this Lease pursuant to
Section 17 hereof and Tenant satisfies the Tenant Leasing Requirement, then the Building shall be called “The Amoco Building,” “The BP Amoco Building,” or, subject to Landlord’s approval (not to be unreasonably
withheld or delayed) such other name as Tenant may elect from time to time during the Term. So long as Landlord has not terminated Tenant’s possession of the Premises or terminated this Lease pursuant to Section 17 hereof, and Tenant satisfies
the Tenant Leasing Requirement, if Tenant changes its corporate name, then the name of the Building, upon written request from Tenant and without the prior consent of Landlord, shall be changed to be consistent with the corporate name change of the
Tenant. If the Tenant requests a change in the name of the Building, such request shall be made in writing at least ninety (90) days prior to the effective date of the new Building name. The Tenant’s right to change the name of the Building to
other than “The Amoco Building” or “The BP Amoco Building” shall be conditioned upon the Tenant paying any and all reasonable Landlord’s Actual Costs (and the costs of other tenants in the Building to the extent Landlord is
responsible for such costs) associated with any name change that it has requested, including, without limitation, the cost of new stationery, new signage and any changes to comply with Requirements. In the event Tenant does not satisfy the Tenant
Leasing Requirement, Landlord shall no longer have the right to use the name “Amoco” (or such new name as Tenant may acquire) in the Building’s name. Tenant’s rights under this 

  

 78 

 
paragraph shall be subject to any limitations on the name or identity of the Building contained in other leases in effect on the Commencement Date. Landlord
shall on even date herewith enter into a Trademark License Agreement with Amoco Oil Company in the form attached hereto as Exhibit O. In the event Tenant elects to change the name of the Building as provided above, the Trademark
License Agreement shall be supplemented, replaced or revised to grant Landlord rights with respect to such name on terms comparable to Exhibit O. 
  
 (b) At all times during the Term, Landlord agrees to maintain the main Building directory and the computerized Building directory (or any replacement
directories thereto) in the Main Lobby and provide Tenant (and Tenant’s subtenants) with a sufficient number of lines on such computer directory in order to list Tenant’s name and all of Tenant’s personnel (and the names and personnel
of Tenant’s subtenants). Landlord shall not be entitled to charge Tenant any fee during the Term for installing Tenant’s initial listings or any additions or changes to any such directories. In addition, Landlord shall during the Term,
identify Tenant on the main Building directory by providing Tenant with six (6) lines on such directory, one to identify the portion of the Building occupied by Tenant and five (5) lines to use as subheadings to indicate the location of various
departments, as indicated by Tenant from time to time. 
  
 (c)
Subject to subparagraph (a) above, Landlord shall maintain Tenant’s exterior signage existing on the Commencement Date. Provided Tenant is satisfying the Tenant Occupancy Requirement at the time such sign rights are proposed, after the
Commencement Date Landlord shall not grant any exterior signage rights (including monument signs) to any other tenant in the Building nor shall Landlord or any tenant place any signage, advertisements, monuments, symbols, emblems or announcements on
the exterior of the Real Property. Notwithstanding the foregoing, Landlord may place non-illuminated signs on one exterior monument for any tenant in the Building so long as such monument (i) is to be located as set forth on Exhibit
J, (ii) is no larger than twenty (20) square feet of total combined surface area (excluding the top), and (iii) is of a design, character, color and material consistent with that of the exterior of the Building; and (iv) Tenant is
given the right to display its name most prominently on such monument (so long as Tenant has the right to name the Building). Tenant may withhold its approval in its sole discretion with respect to exterior signs not satisfying the conditions set
forth in the foregoing sentence. All exterior signage shall be in compliance with all applicable Requirements. Tenant’s rights under this Section 36(c) shall be subject to limitations contained in leases in existence on the Commencement
Date. 
  
 (d) So long as Tenant satisfies the Tenant Occupancy
Requirement, there shall be no signage, advertisements, monuments, symbols, emblems or announcements in the Main Lobby (excluding the directory and any portion of the Main Lobby consisting of the Retail Space) except those signs or other items that
exist as of the Commencement Date or are otherwise approved in writing by Tenant in its reasonable discretion. Tenant’s rights under this Section 36(d) shall be subject to limitations contained in leases in existence on the Commencement
Date. 
  

 79 

 (e) Tenant shall have the right, at Tenant’s sole cost and expense, to install appropriate signage
in Tenant’s (or its subtenant’s) standard graphics identifying Tenant (or its subtenants) in materials and sizes acceptable to Tenant on the walls of the elevator lobbies and on or by the doors on each full floor it leases. On the floors
Tenant partially leases, Tenant may elect to either (i) put its name or the name of its subtenant on the door to the Premises in its (or its subtenant’s) standard graphics or (ii) have Landlord install Tenant’s (or its subtenant’s)
name in building standard graphics on a building standard plaque by the door to the Premises. In addition, Landlord will install building standard directional signs for Tenant (or its subtenants) in the elevator lobbies of any partial floors leased
by Tenant. The building standard plaques and directional signs shall be installed by Landlord as often as Tenant elects but only the first two times on each floor shall be at Landlord’s expense, and any time thereafter Tenant shall reimburse
Landlord for Landlord’s Actual Cost of such plaques and signs. Tenant shall also have the right to install, at its sole cost and expense, intra-office telephones in the elevator lobbies on each floor of the Building which it leases in whole or
in part at a location selected by Tenant, provided such location shall be subject to Landlord’s reasonable approval. 
  
 (f) Tenant shall have the right, at Tenant’s sole cost and expense, to place temporary signs in the Building lobby identifying Tenant’s current
or upcoming corporate events. All such signs shall be tastefully designed and shall be placed in such locations as to not impair the flow of pedestrian traffic through the Building. Upon the completion of an event, Tenant shall promptly remove any
signage related thereto. 
  
 (g) Tenant shall, throughout the
Term, have the right to use the image of the Building in connection with Tenant’s business as Tenant deems appropriate (but in no case for a profit) so long as such image is always displayed in a tasteful manner. 
  
 37. Rooftop Communications Equipment. 
  
 (a) Subject to the terms of this Section 37 and the rights of other
tenants in the Building in existence on the Commencement Date, Tenant shall have the right, but not the obligation, at no additional charge, during the Term to install, maintain and operate, for the exclusive use by tenant or its subtenants (subject
to Section 13(b)), satellite dish antennae or similar rooftop antennae or other devices together with the related cabling, wiring and equipment (collectively, the “Antenna(e)”) on up to fifteen percent (15%) of the
Building’s roof (the “Roof”) and through the Building’s core areas; any such antennae to be installed, maintained or operated on the Roof and through the Building’s core areas shall be of a size, power, frequency and
other specifications as Tenant shall reasonably designate. Landlord hereby consents to Tenant’s continued use and operation of the Antennae in place as of the Commencement Date in their locations as of the Commencement Date. Any Antennae that
Tenant may desire to put on the roof after the Commencement Date shall be placed in locations within Tenant’s fifteen percent (15%) of the Roof and through the Building core as reasonably designated by Landlord (the “Antennae
Sites”) which Tenant shall, subject to Requirements, be permitted to operate continuously upon the terms set forth in this Lease. 

  

 80 

 
Tenant may not sublet any space on the Roof other than in connection with subleases of portions of the Premises. 
  
 (b) Subject to the rights of other tenants in the Building, Landlord shall
have the right to use the remainder of the Roof for any purpose including permitting other tenants in the Building to lease space on the Roof; provided, that (a) Tenant continues to have reasonable access to the Antennae Sites and the Antennae and
(b) any other equipment installed on the Roof pursuant to leases or other agreements entered into after the date of this Lease will not block the ability of the existing Antenna to receive signals or reduce Tenant’s ability to use its existing
Antenna. The Antennae (including, without limitation, all related cables and equipment) installed by Tenant in the Antennae Sites shall remain the property of Tenant. 
  
 (c) Tenant shall install, maintain and operate the Antennae at its sole cost and expense. Tenant shall have access to the
Antennae Sites and a license to enter all portions of the Building necessary to access the Antennae Sites at all times, subject to the Rules and Regulations. At the end of the Term, Tenant may, at Tenant’s sole election, remove the Antennae
from the Building, in which event Tenant shall restore the Antennae Sites to their condition prior to installation of the Antennae. Tenant shall otherwise comply with the terms set forth in Section 9 hereof with respect to the return of the
Antennae Sites. 
  
 (d) Tenant shall comply with all applicable
Requirements governing the installation, maintenance and operation of the Antennae. Tenant shall be responsible for obtaining, if required in connection with its Antennae, any building permits and any licenses or permits required by the Federal
Communication Commission, the Federal Aviation Administration or any other governmental agency having jurisdiction over the Building. If required by any such governmental agencies or by Landlord, Tenant shall paint the dish portion of the Antenna.
Landlord agrees at Tenant’s cost to reasonably assist and cooperate with Tenant to obtain any appropriate licenses or permits. 
  
 38. Expansion Space. (a) Provided Tenant is not in Material Default, satisfies the Tenant Leasing Requirement and has given Landlord written notice
(“Tenant’s Expansion Notice”) of the exercise of each option specified below on the terms and conditions specified below for each option, Tenant will have the option (“Expansion Option”), subject to the terms
of this Section 38 to lease additional space in the Building. 
  
 Provided that Tenant shall have properly exercised its option for the first and second renewal periods in accordance with the terms of Section 1 and so long as Tenant is satisfying the Tenant Occupancy Requirement, upon the
expiration of the first renewal period and no later than the last day of the third (3rd) full month following the end of the first renewal period (“Delivery Window”), Tenant shall have the option to lease one full floor located in
the office portion of the Building (“Expansion Space”). To exercise its option under this Section 38, Tenant must deliver to Landlord, at least twelve (12) calendar months prior to the commencement date of the Delivery Window,
written notification of Tenant’s non-binding intention to expand the Premises. Within ten (10) Business Days after receipt of Tenant’s notification, Landlord shall notify Tenant in writing of the termination date (“First
Lease 

  

 81 

 
Termination Date”) of the earliest to expire of the leases then in effect that would provide Tenant with the Expansion Space. On or before the
later to occur of (i) twelve (12) calendar months prior to the First Lease Termination Date or (ii) thirty (30) days after Landlord notifies Tenant of the First Lease Termination Date, Tenant must deliver Tenant’s Expansion Notice to Landlord
of Tenant’s election to exercise the Expansion Option, which election shall be irrevocable. 
  
 (b) Within fifteen (15) Business Days after delivery of the Tenant’s Expansion Notice, Landlord shall notify Tenant of (i) Landlord’s
determination of the Fair Market Rental Value for the Expansion Space, (ii) the date (“Expansion Space Delivery Date”) during the Delivery Window when Landlord anticipates the Expansion Space is available and (iii) the location of
the Expansion Space Landlord is prepared to deliver. If Tenant objects to Landlord’s determination of Fair Market Rental Value for the Expansion Space, the parties agree to negotiate in good faith to resolve the dispute. If Landlord and Tenant
are unable to resolve the dispute on or before the date that is six (6) months prior to the Expansion Space Delivery Date, then the Fair Market Rental Value shall be determined by Arbitration. 
  
 Except with respect to Base Rent, Tenant shall take such Expansion Space on
the same terms and conditions as are contained in this Lease, including without limitation, a term coterminous with the Term. Base Rent for the Expansion Space shall be ninety-five percent (95%) of the annual Fair Market Rental Value. Rent on the
Expansion Space that is leased by Tenant pursuant to this Section 38, shall commence on the earlier to occur of (x) the date Tenant has substantially completed its tenant improvements for such Expansion Space, subject to punch list items, or
(y) the date that is 120 days after the date Landlord has delivered possession of such Expansion Space to Tenant. The term of this Lease with respect to the Expansion Space shall commence upon the delivery of possession of such space to Tenant and
shall be coterminous with the Term. Landlord agrees that Tenant shall have the right to construct tenant improvements in the Expansion Space in accordance with the terms of this Lease (including the Workletter) and Occupy it prior to the
finalization of any Arbitration; provided Tenant shall pay rent on such Expansion Space equal to the Base Rent and Additional Rent until the Arbitration is resolved. If Tenant has been paying rent on the Expansion Space and the amount of ninety-five
percent (95%) of the Fair Market Rental Value for the Expansion Space as determined by the FMRV Arbitrators is greater or less than the rent Tenant has been so paying, then Tenant shall immediately begin paying ninety-five (95%) of the Fair Market
Rental Value so determined. If the amount of rent Tenant had been paying is less than ninety-five (95%) of the Fair Market Rental Value so determined, Tenant, within fifteen (15) days after such determination, shall pay such difference to Landlord.
If, however, the amount of rent Tenant had been paying is greater than the Fair Market Rental Value so determined, Landlord, within fifteen (15) days after such determination, shall refund such difference to Tenant or give Tenant a credit against
the next installment of Rent due hereunder. 
  
 (c) If Tenant
requests in writing, Landlord shall provide Tenant with an Expansion Space construction allowance for the Expansion Space equal to construction allowances provided to similar tenants leasing similar space in first-class office buildings in 

  

 82 

 
downtown Chicago and the determination of the Fair Market Rental Value of the Expansion Space shall provide for the amortization of the amount, if any, of
the construction allowance provided by Landlord at the rate of ten percent (10%) per annum. All tenant improvements in the Expansion Space shall be constructed, and such allowance shall be paid, in conformance with the provisions set forth in this
Lease (including the Workletter). All Expansion Space shall be delivered to Tenant in Base Building condition and in an “as-is” condition as to any portion that has been previously improved with tenant improvements as of the Expansion
Space Delivery Date. 
  
 39. Tenant’s Right of First Offer
For Additional Space. (a) Subject to any rights of first refusal or first offer in favor of tenants under other leases in the Building in effect on the Commencement Date or renewal or expansion rights (but not first refusal or first offer
rights) granted to tenants in leases entered into after the Commencement Date, provided Tenant is not in Material Default under this Lease and as long as the Tenant Occupancy Requirement is satisfied, and subject to the terms and conditions set
forth in this Section 39, Tenant shall have a right of first offer with respect to any office space located on the floors currently serviced by elevator banks “A” and “B” of the Building in excess of one half (1/2) of a
floor which is available for leasing (“Right of First Offer Space”). Landlord shall, prior to engaging in serious leasing negotiations with a prospective tenant for any Right of First Offer Space, notify Tenant in writing
(“Landlord’s Leasing Notice”) that Landlord intends to lease the Right of First Offer Space. Tenant shall have a period of ten (10) Business Days from the date of delivery of Landlord’s Leasing Notice to notify Landlord in
writing whether Tenant is interested in the subject Right of First Offer Space. 
  
 (a) If Tenant does notify Landlord that it is interested in leasing the subject Right of First Offer Space, then Tenant shall lease the Right of First Offer Space described in Landlord’s Leasing Notice on the
same terms and conditions as are contained in this Lease except (i) Base Rent shall be equal to the annual Fair Market Rental Value, as determined pursuant to the procedures set forth in Section 40, calculated to include a then-market tenant
work allowance which shall be amortized over the remaining term of the Lease at a rate equal to the Prime Rate plus one percent (1 %) per annum. Rent on the Right of First Offer Space shall commence on the later of the date such space is delivered
to Tenant and the date of availability set forth in the Landlord’s Leasing Notice. The term of this Lease with respect to the Right of First Offer Space shall commence upon delivery of possession of such space to Tenant and shall be co-terminus
with the Term. Landlord agrees that Tenant shall have the right to construct tenant improvements in the First Offer Space in accordance with the terms of this Lease (including the Workletter) and Occupy it prior to the finalization of any
Arbitration; provided Tenant shall pay Base Rent on such First Offer Space at the rate being paid with respect to the remainder of the Premises at the time Rent on the Right of First Offer Space commences until the Arbitration is resolved. If Tenant
has been paying Base Rent on the Right of First Offer Space and the amount of the Fair Market Rental Value for the Right of First Offer Space as determined by the FMRV Arbitrators is greater or less than the Base Rent Tenant has been so paying, then
Tenant shall immediately begin paying the Fair Market Rental Value so determined. If the amount of Base Rent Tenant had been paying is less than the Fair Market Rental Value so determined, Tenant, within fifteen (15) Business Days after 

  

 83 

 
such determination, shall pay such difference to Landlord. If, however, the amount of Base Rent Tenant had been paying is greater than the Fair Market Rental
Value so determined, Landlord, within fifteen (15) Business Days after such determination, shall refund such difference to Tenant or give Tenant a credit against the next installment of Rent due hereunder. 
  
 (b) If Tenant (i) has not responded to Landlord’s Leasing Notice within
the aforementioned ten (10) Business Days or (ii) Tenant has rejected such Right of First Offer Space then in all such events it shall be conclusively presumed that Tenant shall have rejected its right of first offer with respect to such Right of
First Offer Space and Tenant’s rights under this Section 39 shall terminate as to such space and Landlord may enter into a lease with any third party (“Third Party Lease”). 
  
 Subject to the terms set forth above, Tenant’s right of first offer for
the Right of First Offer Space shall be continuous throughout the Term and upon the expiration of the Third Party Lease (including any renewals), Tenant shall again have a right of first offer on the terms set forth in this Section 39 with
respect to the space covered thereby. Notwithstanding anything to the contrary in the foregoing, this right of first offer shall not apply with respect to the first lease of any space that was part of the Initial Premises but has been given back to
Landlord pursuant to Tenant’s exercise of a Contraction Right. Further, Tenant shall have no rights of first offer with respect to space that becomes available (y) after the expiration of the tenth (10th) anniversary of the Commencement Date
and (z) after Tenant has assigned the Lease (other than to an Affiliate). 
  
 40. Arbitration. 
  
 (a)
Any dispute arising out of the following matters under this Lease, upon written notice from one party to the other, shall be resolved by arbitration (“Arbitration”): 
  

	 	(i)	 	services to be provided by Landlord; 

  

	 	(ii)	 	Landlord’s and Tenant’s respective maintenance obligations; 

  

	 	(iii)	 	the existence of a Reduction of Services or Untenantability and the applicable abatement or termination right therefore, if any; 

  

	 	(iv)	 	the exercise by Tenant of any self-help remedies; 

  

	 	(v)	 	the amount and duration of any Rent abatement; 

  

	 	(vi)	 	the existence of any non-monetary defaults; 

  

	 	(vii)	 	the calculation of Additional Rent; 

  

	 	(viii)	 	the reasonableness of any refusal to consent to the making of a Structural Alteration by Tenant or to an assignment or subletting; 

  

 84 

	 	(ix)	 	a reduction in the number of security attendants; and 

  

	 	(x)	 	the determination of Comparable Buildings. 

  
 Arbitration shall be binding upon the parties unless expressly set forth to the contrary herein. The party desiring Arbitration shall give written notice
(“Arbitration Notice”) that it is invoking Arbitration to resolve a dispute, in which event the following terms and conditions shall apply and the matter shall be submitted to Arbitration pursuant to the Expedited Procedures of the
AAA Arbitration Rules for the Real Estate Industry. Unless otherwise mutually agreed to by the parties, all Arbitration proceedings shall be conducted in downtown Chicago, Illinois. 
  
 (b) With respect to issues or disputes arising under the terms of this Lease other than the determination of Fair Market
Rental Value, the parties hereto agree that: 
  
 (i) The number of arbitrators (“Designated Arbitrator(s)”) shall be three (3), unless no disclosed claim or counterclaim in the dispute exceeds $50,000, in which case there shall be a single Designated Arbitrator. The
parties shall request that the AAA select each Designated Arbitrator. Each Designated Arbitrator shall be a person who shall have had at least ten (10) years’ experience in the real estate business in Chicago, Illinois which is directly
relevant to the subject matter of the dispute, shall be impartial and shall be independent of Landlord and Tenant. The AAA’s decision that a Designated Arbitrator meets these requirements shall be final and binding. The Designated Arbitrators
shall not be changed unless both Landlord and Tenant jointly approve a replacement arbitrator, who shall in all respects meet the qualifications of a Designated Arbitrator as set forth above. 
  
 (ii) The Arbitration shall be conducted, to the extent
consistent with this Section 40, in accordance with the then prevailing rules of the AAA. To the extent that the Illinois Uniform Arbitration Act or any successor statute imposes requirements different than those of the AAA in order for the
decision of the Designated Arbitrators to be enforceable in the courts of the State of Illinois, such requirements shall be complied with in the Arbitration. The Designated Arbitrators shall render their decision and award in writing within thirty
(30) days after the date the dispute is referred to them. Landlord and Tenant agree to respond expeditiously to discovery requests and agree to bring the Arbitration proceedings to a close as quickly as is reasonably possible. Such decision and
award shall be binding and conclusive on the parties, shall constitute an “award” by the Designated Arbitrators within the meaning of the AAA rules and applicable Requirements, and counterpart copies thereof shall be delivered to each of
the parties. In rendering such 

  

 85 

 
decision and award, the Designated Arbitrators shall not add to, subtract from or otherwise modify the provisions of this Lease. 
  
 (iii) All expenses and fees of the Arbitration (other than
the fees and disbursements of attorneys or witnesses for each party) shall be borne by the losing party, which party shall be designated by the Designated Arbitrators. 
  
 (c) When so required by the provisions of this Lease, the annual Fair Market Rental Value of the Premises shall be
determined in accordance with the following provisions: 
  
 (i) If Landlord or Tenant desires to invoke the Arbitration procedure set forth in this Section 40, the party invoking the Arbitration procedure shall give an Arbitration Notice to the other party, stating that
the party sending the Arbitration Notice desires to meet within ten (10) days to attempt to agree on a single arbitrator to determine the annual Fair Market Rental Value of the Premises (the “FMRV Arbitrator”). If Landlord and
Tenant have not agreed on the Arbitrator within thirty (30) days after the giving of the Arbitration Notice, then either Landlord or Tenant, on behalf of both, may apply to the Chicago office of the AAA for appointment of the FMRV Arbitrator in
accordance with the requirements set forth in Subsection (c)(ii)(B). The date on which the FMRV Arbitrator is appointed, by the agreement of the parties or by appointment by the AAA is referred to herein as the “Appointment
Date”. If any FMRV Arbitrator appointed hereunder shall be unwilling or unable, for any reason, to serve, or continue to serve, a replacement arbitrator shall be appointed in the manner set forth above. 
  
 (ii) The Arbitration shall be conducted in accordance with
the then prevailing rules of the AAA, modified as follows: 
  
 (A) To the extent that the Illinois Uniform Arbitration Act or any successor statute imposes requirements different than those of the AAA in order for the decision of the FMRV Arbitrator to be enforceable in the
courts of the State of Illinois, such requirements shall be complied with in the Arbitration. 
  
 (B) The FMRV Arbitrator shall be impartial, shall not be affiliated with Landlord or Tenant and shall be a leasing broker with at least
ten (10) years’ experience in the valuation of fair market rentals for comparable size leases in comparable office buildings in downtown Chicago. 
  
 (C) Before hearing any testimony or receiving any evidence, the FMRV Arbitrator shall be sworn to hear and decide 

  

 86 

 
the controversy faithfully and fairly by an officer authorized to administer an oath and a written copy thereof shall be delivered to Landlord and Tenant.

  
 (D) Within thirty (30) days after the
Appointment Date, Landlord and Tenant shall deliver to the FMRV Arbitrator two (2) copies of their respective written determinations of the annual Fair Market Rental Value of the Premises (each, a “Determination”), together with
such affidavits, appraisals, reports and other written evidence relating thereto as the submitting party deems appropriate. After the submission of its Determination, neither party may make any additions to or deletions from, or otherwise change,
its Determination. If either party fails to so deliver its Determination within such time period, time being of the essence with respect thereto, such party shall be deemed to have irrevocably waived its right to deliver a Determination and the FMRV
Arbitrator, without holding a hearing, shall accept the Determination of the submitting party as the annual Fair Market Rental Value of the Premises. If each party submits a Determination with respect to the annual Fair Market Rental Value of the
Premises within the thirty (30) day period described above, the FMRV Arbitrator shall, promptly after its receipt of the second Determination, deliver a copy of each party’s Determination to the other party, together with copies of all
materials submitted therewith. If the higher of the Determinations so submitted by the parties exceeds the lower of such Determinations by not more than five percent (5%) of the lower Determination, then the FMRV Arbitrator, without holding a
hearing, shall determine that the annual Fair Market Rental Value of the Premises is the mathematical average of the two Determinations thereof. 
  
 (E) If the annual Fair Market Rental Value of the Premises has not been determined pursuant to clause (D) of this subparagraph, then not
less than fifteen (15) days nor more than thirty (30) days after the earlier to occur of (A) the expiration of the thirty (30) day period provided for in clause (D) of this subparagraph or (B) the FMRV Arbitrator’s receipt of both of the
Determinations from the parties (such earlier date is referred to herein as the “Submission Date”), and upon not less than ten (10) days’ notice to the parties, the FMRV Arbitrator shall hold one or more hearings with respect
to the determination of the annual Fair Market Rental Value of the Premises. The hearings shall be held in downtown Chicago at such location and time as shall be specified by the FMRV Arbitrator. Each of the parties shall be entitled to present all
relevant evidence and to cross examine witnesses at the hearings. The FMRV Arbitrator shall have the 

  

 87 

 
authority to adjourn any hearing to such later date as the FMRV Arbitrator shall specify, provided that in all events all hearings with respect
to the determination of the annual Fair Market Rental Value of the Premises shall be concluded not later than forty-five (45) days after the Submission Date. 
  

(F) Except as otherwise provided in clause (D) of this subsection, the FMRV Arbitrator shall be instructed, and shall be empowered
only, to select as the annual Fair Market Rental Value of the Premises that one of the Determinations which the FMRV Arbitrator believes is the more accurate determination of the annual Fair Market Rental Value of the Premises. Without limiting the
generality of the foregoing, in rendering his or her decision, the FMRV Arbitrator shall not compromise between the two Determinations nor add to, subtract from or otherwise modify the provisions of this Lease or either of the Determinations.

  
 (G) The FMRV Arbitrator shall render his or
her determination as to the selection of a Determination in a signed and acknowledged written instrument, original counterparts of which shall be sent simultaneously to Landlord and Tenant, within ten (10) days after the earlier to occur of (A) his
or her determination of the annual Fair Market Rental Value of the Premises pursuant to clause (D) of this subparagraph or (B) the conclusion of the hearing(s) required by clause (E) of this subparagraph. 
  
 (iv) This provision shall constitute a written agreement to
submit any dispute regarding the determination of annual Fair Market Rental Value of the Premises to Arbitration. 
  
 (v) The Arbitration decision, determined as provided in this Section 40(c), shall be conclusive and binding on the parties, shall
constitute an “award” by the Arbitrator within the meaning of the AAA rules and applicable Requirements and judgment may be entered thereon in any court of competent jurisdiction. 
  
 (vi) All expenses and fees of the Arbitration (other than
the fees and disbursements of attorneys or witnesses for each party) shall be borne by the losing party, which party shall be designated by the FMRV Arbitrators unless the annual Fair Market Rental Value of the Premises was determined in accordance
with clause (D) of this Section 40(c) in which event such expenses and fees shall be split equally between Landlord and Tenant. 
  

 88 

 41. Sale of Building; Right of First Offer. (a) If at any time Landlord desires to sell the
Building or the Building and the Land, then it shall deliver a notice (a “Sale Notice”) to Tenant stating that it desires to sell the Building or the Building and the Land. At any time within thirty (30) days after receipt of the
Sale Notice (the “OTP Offer Period”), Tenant may give Landlord a written notice (an “Offer to Purchase”) containing an offer by Tenant to purchase the Building or the Building and the Land (as indicated in the Sale
Notice) for a specified purchase price, payable entirely in cash at closing, and setting forth the other material terms of such offer (other than the proposed closing date which shall be as set forth below). At any time within thirty (30) days after
receipt of the Offer to Purchase (the “OTP Response Period”), Landlord, in its discretion shall either: 
  
 (i) give Tenant written notice advising Tenant that Landlord has accepted the Offer to Purchase (the “Acceptance
Notice”), in which event Landlord and Tenant shall diligently proceed in good faith to satisfy any conditions set forth in such Offer to Purchase and complete such sale of, and transfer of title to, the Building or the Building and the
Land, as applicable, on the thirtieth (30th) Business Day after the date on which the Acceptance Notice was received by Tenant (or on such other day as Landlord and Tenant may agree). If Landlord and Tenant are unable, after exercising good faith
efforts, to satisfy such conditions and complete the sale of, and transfer of title to, the Building or the Building and the Land, as applicable, within sixty (60) Business Days after Tenant’s receipt of the Acceptance Notice, Landlord shall,
subject to Section 41(e), have the right to sell the Building or the Building and the Land, as applicable, to a third party free and clear of the rights of Tenant under this Section 41; or 
  
 (ii) give Tenant written notice advising Tenant that
Landlord has rejected the Offer to Purchase (the “Rejection Notice”). If a Rejection Notice is given, Landlord shall not sell the Building or the Building and the Land, as applicable, for a price equal to less than ninety-five
percent (95%) of the price specified in the Offer to Purchase, without first delivering a new Sale Notice to Tenant and following the procedures set forth above. 
  
 If Landlord fails to give an Acceptance Notice or a Rejection Notice prior to the expiration of the OTP Response Period, then Landlord shall
be deemed to have given a Rejection Notice as of the date of expiration of the OTP Response Period. 
  
 (b) If Tenant fails to send an Offer to Purchase within the OTP Offer Period, then Tenant shall, within ten (10) Business Days of request by Landlord,
deliver a certificate confirming that Tenant has waived its right of first offer with respect to the Sale Notice (subject to the provisions of paragraph (e) below). 
  
 (c) Notwithstanding anything to the contrary contained herein, the delivery of the Offer to Purchase or the Acceptance
Notice shall not be deemed to constitute a contract between Landlord and Tenant with respect to the matters set forth therein and neither party 

  

 89 

 
shall be legally bound in connection therewith until such time as both parties execute a sale contract. 
  
 (d) Tenant’s right of first offer under this Section 41 shall not
apply to any Sale (i) to an Affiliate of Landlord or (ii) completed or committed to during any period that (y) Tenant is in Material Default or (z) the Tenant Occupancy Requirement is not satisfied. In addition, Tenant’s right of first offer
under this Section 41 shall specifically not apply to an acquisition by a lender through foreclosure, or deed in lieu of foreclosure, or purchaser therefrom, provided such transaction is a bona fide financing arrangement and not intended to
transfer all or any portion of the ownership or control rights of the Building or the Building and the Land whether directly or indirectly or by operation of law. 
  
 (e) If Landlord has not consummated a sale of the Building within eighteen (18) months after the delivery of the Sale
Notice, Landlord shall again be required to offer the Building or the Building and the Land to Tenant under the procedures set forth herein. If a sale of the Building to a third party is consummated within eighteen (18) months after the delivery of
the Sale Notice, then Tenant shall have no further rights under this Lease to receive a first offer on any future sales of the Building or the Building and the Land. 
  
 42. 79th Floor Cancellation Right. (a) Tenant shall have the right, exercisable upon not less than six (6) months
prior written notice to Landlord, to terminate this Lease with respect to the 79th Floor Premises only, effective on the date specified in Tenant’s notice. Tenant shall not be liable for any fee, charge or other payment because of such
termination, including, without limitation, any fee to reimburse Landlord for its unamortized costs associated with this Lease (e.g., brokerage costs). 
  
 (b) In the event of such a termination, Tenant shall deliver the 79th Floor Premises to Landlord in an “AS IS” “WHERE IS” condition,
without any requirement to remove Tenant’s Property or to perform repairs, improvements or other work, and otherwise in accordance with Section 9. 
  

(c) Following the effective date of such a termination (if any), the term “Premises” under the Lease shall no longer include of the
79th Floor Premises, and Landlord and Tenant shall execute a modification to the Lease to reflect such surrender and to amend such other terms and provisions of the Lease which are affected by a reduction in the size of the Premises, including, but
not limited to, the amount of the Base Rent, Tenant’s Proportionate Share for Expenses and Tenant’s Proportionate Share for Taxes. 
  
 (d) Notwithstanding anything to the contrary contained in Section 1(b)(i)(c), Tenant shall be permitted to exclude the 79th Floor Premises from the
exercise of the renewal rights provided for hereunder. 
  

 90 

 43. Parking. 
  
 (a) Landlord shall, subject to all applicable Requirements, provide Tenant (or its subtenants), at Tenant’s option,
with the following parking spaces in the Garage at the following costs during the entire Term: 
  
 (i) eighteen (18) reserved spaces in the Parking Area 1A, as designated on Exhibit B, the current size of which shall not be
changed throughout the Term without Tenant’s reasonable consent, at a monthly cost equal to rates competitive with other comparable parking facilities in comparable locations in downtown Chicago; 
  
 (ii) twenty (20) reserved spaces in the Monthly Parking
Area, at a monthly cost equal to rates competitive with other comparable parking facilities in comparable locations in downtown Chicago; 
  
 (iii) up to fifty (50) parking spaces in the Monthly Parking Area at a monthly cost equal to rates competitive with other comparable
parking facilities in comparable locations in downtown Chicago; and 
  
 (iv) up to an additional one hundred (100) parking spaces, which may be located in any portion of the Garage, at a monthly cost equal to rates competitive with other comparable parking facilities in comparable
locations in downtown Chicago; provided, however, the number of parking spaces provided to Tenant pursuant to this Section 43(a)(iv) shall be proportionately reduced in the event Tenant exercises any of the Contraction Rights or Landlord
exercises its recapture rights. 
  
 Tenant shall have the
aforementioned parking rights at all times during the Term, regardless of whether or not Tenant uses or leases such spaces at all times during the Term. Landlord or the owner of the Garage shall have the right to adjust the published monthly rates
from time to time provided they are competitive with the rates for comparable parking facilities in comparable locations in downtown Chicago, but in no event shall such rates be in excess of the Most Favored Tenant Rate (with the exception of free
parking). Landlord agrees to use reasonable efforts to accommodate Tenant’s additional parking needs during the entire Term. Subject to the Requirements, the Garage will be accessible twenty-four (24) hours a day, every day of the year during
the Term. Tenant’s employees using parking spaces leased monthly shall be permitted to enter and exit the Garage an unlimited number of times per day at no additional charge. 
  
 (b) Landlord, at its sole cost and expense, shall maintain, or cause to be maintained, the Chauffeur’s Lounge existing
as of the Commencement Date, which office/lounge shall be heated and cooled to reasonable levels for occupancy by the chauffeur(s) of Tenant or its employees, have electric service and have a telephone line available for 
  

 91 

 
Tenant’s use. Tenant (and Tenant’s subtenants) shall have exclusive use of the Chauffeur’s Lounge. 
  
 44. Press Releases; Confidentiality. (a) All press releases concerning
Landlord’s and Tenant’s execution of this Lease, the length of the Lease, size of Premises, location of Premises and the individuals involved, shall be subject to the prior approval of Tenant and Landlord. 
  
 (b) Notwithstanding the foregoing, it is expressly understood and agreed to
by the Landlord and Tenant that the terms and conditions set forth in this Lease and the related negotiations contain information which the parties desire to remain strictly confidential. Therefore, except as otherwise set forth herein, the parties
hereto agree that they shall each use their reasonable efforts to restrict the circulation of this Lease, the Workletter and other attached exhibits and all term sheets and letters of intent relating to this Lease and the information contained in
each of the foregoing, only to persons who are then in the employment of such party without first obtaining the prior written consent of the other party, provided that both Landlord and Tenant may disclose portions of the Lease or related
information to their attorneys, accountants and consultants (including real estate brokers and agents and, in the case of Landlord, all employees of Manager or any other entity managing the Building) in connection with their work on or
administration of this Lease or the Premises or with respect to either such party’s business affairs, provided that Landlord and Tenant further agree to inform such parties of the terms of this Section 44 and use their reasonable efforts
to cause such parties to keep such information confidential. In addition, Tenant may provide a copy of this Lease to potential subtenants and assignees and their brokers, agents and consultants; and Landlord may disclose this Lease and its terms to
its partners, investors, agents, consultants, affiliates, potential transferees of all or any partial interest in the Land and/or Building, whether direct or indirect, and potential Mortgagees and each of their brokers, agents and consultants.

  
 45. Environmental Covenants. (a) From and after
the Commencement Date and during the remainder of the Term, Landlord shall at its sole cost and expense comply with all Requirements that regulate environmental matters (“Environmental Laws”) relating to the Real Property. Landlord
is responsible for, and agrees to hold harmless, indemnify and defend Tenant from and against any and all claims, damages, costs and liabilities related to the presence of any Hazardous Substances in or on the Premises or the Real Property that were
brought onto the Real Property by Landlord (or its agents or contractors), except to the extent caused by either (i) by Tenant (or its agents or contractors) or (ii) a condition or occurrence that existed on the Real Property on or prior to the
Commencement Date. 
  
 (b) Tenant shall comply, and take all
necessary actions to cause its operations on the Premises to comply, with all applicable Environmental Laws. Tenant agrees to hold harmless, indemnify and defend Landlord from and against any and all claims, damages, costs and liabilities related to
the presence of any Hazardous Substances brought into or placed in the Premises or the Real Property after the Commencement Date by Tenant or, its agents, employees, contractors), or Tenant’s Affiliates. 
  

 92 

 46. Building Plaza. Tenant shall have the right, upon reasonable notice to Landlord, to
utilize the Building plaza for Tenant’s corporate and charitable events. Tenant’s use of the Building plaza shall in no event prevent access to and from the Building and shall at all times be in compliance with the Plaza Use Policy, a copy
of which is attached hereto and made a part hereof as Exhibit F. Landlord agrees that all Building tenants making use of the Building plaza shall be required to comply with a policy which is the same or substantially similar to
the Plaza Use Policy. 
  
 47. Other Agreements; Release of
Tenant. 
  
 (a) Notwithstanding anything to the contrary
contained in this Lease, Landlord and Tenant acknowledge and agree that neither Landlord nor Tenant shall have any right to set-off, apply or appropriate (x) any distribution or other amounts due to the other party or one of its Affiliates under the
Contribution Agreement, the LLC Agreement or any other contract or agreement (other than this Lease and documents directly relating hereto, including, without limitation, the Subordination, Non-Disturbance and Attornment Agreement (Lender) and the
Non-Disturbance and Attornment Agreement (Sub-Tenant), forms of which are attached hereto) to which one or more of Landlord, Tenant and/or any of their respective Affiliates is a party against (y) any amounts due to Landlord or Tenant hereunder.

  
 (b) Landlord acknowledges that Tenant and one or more
Affiliates constructed, owned and managed the Property prior to Landlord’s acquiring title thereto and that Landlord does not and will not make or raise any claims, defenses, demands, causes of action, losses, damages or liabilities against
Tenant under this Lease on the basis of such prior construction, ownership and/or management or any other acts or omissions occurring prior to the Commencement Date.

 WITNESSETH: 
  
 WHEREAS, Landlord, as landlord, and Tenant, as tenant, entered into a
certain Office Lease dated as of December 11, 1998 (the “Original Lease”) with respect to (among other things) Tenant’s lease of certain premises located at The Amoco Building, 200 E. Randolph Drive, Chicago, Illinois; and 

 
 WHEREAS, Landlord and Tenant desire to amend the Original Lease
upon the terms and provisions set forth in this Amendment. 
  
 NOW, THEREFORE, in consideration of the sum of Ten and no/100 Dollars ($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant do hereby agree as follows:

  
 1. Definitions. All capitalized terms used herein but
not defined herein shall have the meanings ascribed to such terms in the Original Lease. The term “Lease”, as used in the Original Lease and this Amendment, shall mean the Original Lease as amended by this Amendment. 
  
 2. Modification of Section 4. Section 4 of the Original Lease is
hereby deleted in its entirety and replaced with the following: 
  
 “4. Contraction Option. 
  
 (a) Tenant shall
have one (1) contraction option with respect to the Premises on the terms set forth below. Provided that Tenant is not in Material Default under this Lease, Tenant shall have the right, exercisable upon not less than twelve (12) months prior written
notice to Landlord (the “Contraction Notice”), to reduce the size of the Premises (the “Contraction Right”) by surrendering a portion thereof (the “Surrendered Space”) to Landlord 
  
  

 
effective as set forth below: 
  

	 Contraction Space Allowed

	 	 Effective Date of Contraction

	The space depicted on Exhibit A-1 attached hereto and made a part hereof (the “Contraction Space”)	 	 December 11, 2001 (the “Contraction Date”)

  
 The exercise by Tenant
of the foregoing Contraction Right shall be subject to the following conditions: 
  
 (i) To the extent Tenant does not exercise its Contraction Right with respect to any portion of the Contraction Space effective on the
Contraction Date, Tenant will be deemed to have waived its Contraction Right with respect to such portion of the Contraction Space; and 
  
 (ii) Tenant may elect to exercise the Contraction Right with respect to less than all of the Contraction Space provided that the portion
of the Premises to be deleted as a result of the exercise of Tenant’s Contraction Right shall: 
  
 (A) be full floors (except that the Surrendered Space may include only a portion of the highest floor of the Contraction Space so long as
Tenant retains at least approximately one-half of the Rentable Square Feet on such floor), not including any space that has been recaptured by Landlord pursuant to Section 13(c), 
  
 (B) if the Surrendered Space is located on more than one (1) floor of the Building, such Surrendered Space
shall be located on contiguous floors (not including the space located on the 33rd floor of the Building, any space that has been recaptured by Landlord pursuant to Section 13(c)) so that the remaining portion of the Contraction Space, after
giving effect to such contraction, shall be located on contiguous floors (not considering the space located on the 33rd floor of the Building, any space recaptured by Landlord pursuant to Section 13(c)), and 
  
 (C) constitute the highest floors contained in the
Contraction Space which are then leased by Tenant. 

 The Contraction Notice shall specify the size, location and configuration of the Surrendered Space. The
size of the Surrendered Space shall be determined, subject to the limitations set forth above, in Tenant’s sole discretion. The Surrendered Space shall be in a legally leasable configuration, and to the extent the Tenant elects to contract the
Premises on only a portion of a floor, the space to be deleted from the Premises on such floor shall have reasonable access to the elevator lobbies and bathrooms on that floor. 
  
 (b) In the event that the Surrendered Space constitutes less than all of the space occupied by Tenant on a given floor or
floors of the Building, then Tenant shall pay to Landlord, upon demand, one-half of Landlord’s Actual Costs of the construction of the demising walls necessary to segregate and demise the portion of the Premises remaining on such floor and to
provide access for such Surrendered Space to the elevator lobbies and bathrooms on that floor and Tenant shall be responsible for no other costs or expenses. 
  
 (c) Except as otherwise provided in Section 6 or Section 9 hereof, Tenant shall deliver the Surrendered Space to Landlord in an “AS
IS” “WHERE IS” condition, without any requirement to remove Tenant’s Property or to perform repairs, improvements or other work, regardless of whether or not such space, upon delivery to Landlord, complies with Requirements,
provided that Tenant shall repair any damage to the Building (other than to the paint, carpeting or wall covering) caused by the removal of Tenant’s Property upon request of Landlord delivered within five (5) days after Tenant has vacated the
Surrendered Space and shall remove the Structural Alterations in the Surrendered Space that Landlord required Tenant to remove as a part of Landlord’s consent to such Structural Alterations pursuant to Section 6(d). Except as expressly
set forth in this Section 4. Tenant shall not be liable to Landlord for any fee, charge or other payment because of such contraction, including, without limitation, a fee to reimburse Landlord for its unamortized costs associated with this
Lease (e.g., brokerage costs). 
  
 (d) If Tenant shall have
exercised its Contraction Right, then, following the Contraction Date, the term “Premises” under the Lease shall no longer consist of the Surrendered Space, and Landlord and Tenant shall execute a modification to the Lease to reflect such
surrender and to amend such other terms and provisions of the Lease which are affected by a reduction in the size of the Premises, including, but not limited to, the Base Rent, Tenant’s Proportionate Share for Expenses and Tenant’s
Proportionate Share for Taxes. 
  
 (e) Tenant’s Contraction
Right shall not apply to any space within the Contraction Space with respect to which Landlord has properly exercised its Contraction Space Recapture Right (as hereinafter defined) (and with respect to which all of the Contraction 

 
Space Recapture Conditions (as hereinafter defined) have been satisfied); provided, that no such exercise of the Contraction Space Recapture Right (or
satisfaction of the Contraction Space Recapture Conditions) shall have any effect whatsoever on the Tenant’s exercise of its Contraction Right with respect to any portion of the Contraction Space with respect to which Landlord has not properly
exercised the Contraction Space Recapture Right (or any portion of the Contraction Space with respect to which all of the Contraction Space Recapture Conditions have not been satisfied). Tenant’s Contraction Right described above shall not
apply to any Contraction Sublease Space (as hereinafter defined).”

Space Recapture Conditions) have been satisfied: 
  
 (i) Landlord shall exercise the Contraction Space Recapture Right with respect to all (and not less than all) of the space leased by Tenant on any floor located within the Contraction Space. In no event may the Contraction Space Recapture

of the Lease), so that the remaining portion of the Contraction Space, after giving effect to such recapture, shall be located on contiguous floors (not considering the space located on the 33rd floor of the Building, any Contraction Sublease
Space (as hereinafter defined) or any space recaptured by Landlord pursuant to Section 13(c) of the Lease); 
  
 (iii) The floor(s) of the Contraction Space with respect to which Landlord exercises the Contraction Space Recapture Right shall

“Contraction Space Recapture Date”) on which Landlord desires to recapture such floor(s) of the Contraction Space from Tenant; provided, that, notwithstanding anything to the contrary herein, in no event shall any Contraction Space
Recapture Date be: 
  
 (w) later than the
Contraction Date for any Contraction Space whatsoever, 
  
 (x) earlier than thirty (30) days after the date on which the applicable Contraction Space Recapture Notice is received by Tenant, with respect to any portion of the Contraction Space identified in such Contraction Space Recapture Notice
which is substantially vacant and unoccupied by Tenant (and any other person or entity entitled to occupy such space) on the date on which such Contraction Space Recapture Notice is received by Tenant, 
  
 (y) earlier than sixty (60) days after the date on which the

 99 

 
or options to sublease) all or any portion of the Contraction Space to any person or entity (any such portion of the Contraction Space identified in any such
Contraction Space Sublease Notice being referred to herein as “Contraction Sublease Space”). In the event that Tenant delivers any such Contraction Space Sublease Notice identifying any such Contraction Sublease Space, and Landlord has
not, prior to such delivery of such Contraction Space Sublease Notice, delivered to Tenant a Contraction Space Recapture Notice with respect to such Contraction Sublease Space, then, from and after the delivery of any such Contraction Space Sublease
Notice by Tenant to Landlord, the Contraction Sublease Space described in such Contraction Space Sublease Notice shall no longer constitute a portion of the Contraction Space for purposes of Sections 4 and 4A of the Lease and, accordingly, neither
the Tenant’s Contraction Right set forth in Section 4, nor the Landlord’s Contraction Space Recapture Right set forth in Section 4A, shall apply to such Contraction Sublease Space.

Tenant’s Property upon request of Landlord delivered within five (5) days after Tenant has vacated the applicable Recaptured Contraction Space, and (y) remove the Structural Alterations in the Recaptured Contraction Space that Landlord required
Tenant to remove as a part of Landlord’s consent to such Structural Alterations pursuant to Section 6(d) of the Lease;

Base Rent which accrues under the Lease with respect to the applicable Recaptured Contraction Space within the period (the “Recapture Rent Period”) which commences on the applicable Contraction Space 

  

 100 

 
Recapture Date and terminates on the Contraction Date; 
  
 (C) Tenant shall pay to Landlord, no later than the applicable Recapture Payment Date, an amount equal to the product of: 
  
 (x) sixty-five percent (65%), multiplied by 
  
 (y) the aggregate amount of Additional Rent which is
estimated to accrue under the Lease within such Recapture Rent Period, as reasonably determined by Landlord based on the most recent Landlord’s Statements, which amount shall be subject to reconciliation upon final determination of the actual
Additional Rent (in accordance with, and subject to the terms and provisions of the Lease (including, without limitation, Section 2 thereof, and any and all rights of Tenant to object to, challenge, audit and/or protest the amount of such Additional
Rent)) which has accrued during such Recapture Rent Period; 
  
 (D) Notwithstanding anything to the contrary contained in the foregoing, in the event that a Monetary Landlord Default exists and is continuing on any Recapture Payment Date, then (in addition to, and not in lieu of,
each and all of the other rights and remedies to which Tenant is entitled under the Lease) Tenant shall have the right to offset the amount of any such Monetary Landlord Default against any payment or amount due under Subsections (B) and/or (C)
above from Tenant to Landlord; and 
  
 (E)
Following the applicable Contraction Space Recapture Date, the term “Premises” under the Lease shall no longer consist of the applicable Recaptured Contraction Space, and Landlord and Tenant shall execute a modification to the Lease to
reflect such reduction in the size of the Premises, and to amend such other terms and provisions of the Lease which are affected by such a reduction in the size of the Premises, including, but not limited to, the Base Rent, Tenant’s
Proportionate Share for Expenses and Tenant’s Proportionate Share for Taxes.

without limitation, any fee to reimburse Landlord for its unamortized costs associated with the Lease (e.g., brokerage costs).” 
  
 4. Governing Law. The Original Lease and this Amendment shall be governed by, and construed in accordance with, the laws of the State of Illinois.

 W I T N E S S E T H: 
  
 WHEREAS, Landlord, as landlord, and Tenant, as tenant, entered into a certain Office Lease dated as of December 11, 1998 (the “Unmodified
Lease”) with respect to (among other things) Tenant’s lease of certain premises located at The Amoco Building (now known as The Aon Center), 200 East Randolph Drive, Chicago, Illinois; and 
  
 WHEREAS, the Unmodified Lease was amended by that certain First
Amendment to Office Lease between Landlord and Tenant dated as of July 30, 1999 (the Unmodified Lease, as so amended, is sometimes referred to as the “Original Lease”); and 
  
 WHEREAS, Landlord and Tenant desire to amend the Original Lease upon the terms, provisions and conditions set forth
in this Second Amendment. 
  
 NOW, THEREFORE, in
consideration of the sum of Ten and no/100 Dollars ($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant do hereby agree as follows: 
  
 1. Definitions. All capitalized terms used herein but not

reference (the “Substitution Podium Space”), shall be substituted for that portion of the Podium Space specifically identified on Exhibit A attached hereto, consisting of 4,492 Rentable Square Feet (the “Former Podium
Space”), such that, from and after the Effective Date, the Podium Space shall include the Substitution Podium Space and exclude the Former Podium Space. Effective as of the Effective Date, Landlord and Tenant further agree as follows:

  
 (a) The term “Podium Space”, as set
forth in the Definitions Section of the Original Lease, is deleted and replaced with the following: 
  
 “Podium Space” shall mean the space identified as the “Podium Space” on Exhibit B-1 attached to
this Second Amendment, which shall include the Chauffeur’s 

 
Lounge and which shall as of the Effective Date be deemed to consist of 45,754 Rentable Square Feet;

 From and after the
Effective Date, no Additional Rent for Tenant’s Proportionate Share for Taxes and Tenant’s Proportionate Share for Expenses shall be due with respect to the Podium Space but Tenant shall continue to be liable for all additional/special
services and utilities provided to the Podium Space to the extent provided in the Original Lease. 
  
 (d) Provided Tenant is not in Default under the Lease, Landlord agrees to give Tenant a credit against Monthly Rent for the Podium Space
in the amount of One Hundred Fifty-Five Thousand Eight Hundred and Thirty-Six Dollars and 16/100 ($155,836.16), which credit shall be applied against the installments of Monthly Rent for the Podium Space first coming due after the Effective Date (in
order of payment). This credit is in full settlement of all claims by Tenant for overpayment of Rent with respect to the Former Podium Space. 
  
 (e) Tenant shall cause the consumption of electricity within the Former Podium Space to be subtracted from the meter which measures the
consumption of electricity in the Podium Space and, upon notice to Landlord that Tenant has completed such subtraction, Landlord shall cause the consumption of electricity within the Former 

  

 2 

 
Podium Space to be metered to Landlord. Tenant agrees to reimburse Landlord for one-half of the direct, actual third party reasonable expenses to install the
new meter within thirty (30) days after written request or, at Tenant’s option, together with its payment of its next installment of Rent. 
  
 (f) Within sixty (60) days after the Effective Date, Landlord shall, at Landlord’s cost, separately demise the Substitution Podium
Space (such that such space is separated from all other space in the Building other than other Podium Space leased by Tenant), and install a door in a reasonable location at the Substitution Podium Space providing reasonable access to and from such
Substitution Podium Space. 
  
 3. Relocation of 79th Floor Premises. 
  
 (a) At the
request of Landlord and at Landlord’s sole cost and expense, Tenant has agreed to relocate from the 79th Floor
Premises to two separate office spaces, located on the 69th floor of the Building, and known as Suite 6952
(consisting of approximately Two Thousand Four Hundred Ninety (2,490) rentable square feet) and known as Suite 6948 (consisting of approximately Two Thousand Thirty-Five (2,035) rentable square feet) (collectively, the “69th Floor Premises”), each suite as further depicted on Exhibit C attached hereto and incorporated herein by
this reference. Tenant hereby acknowledges that, with Tenant’s prior review and approval of the space plan and specifications therefor, Landlord has improved the 69th Floor Premises in a manner substantially similar to the 79th Floor Premises, and that the 69th Floor Premises are ready for
occupancy. Tenant has inspected the 69th Floor Premises and agrees to accept the same “as is” without any
agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements and no representations respecting the condition of the 69th Floor Premises, except as expressly provided herein. 
  
 (b) Tenant agrees to take occupancy of the 69th Floor Premises on or before the date that is thirty (30) days after the Effective Date (the “Occupancy Date”) and Tenant agrees to cooperate fully and promptly with Landlord in connection
with the physical relocation to the 69th Floor Premises. Tenant shall, at such times and in such manner as mutually
agreed with Landlord, vacate and surrender to Landlord the 79th Floor Premises and relocate to the 69th Floor Premises no later than the Occupancy Date. At Landlord’s expense, Landlord shall cause Tenant’s personal
property and equipment located in the 79th Floor Premises to be moved to the 69th Floor Premises no later than the Occupancy Date (“Landlord Move”). Prior to the Landlord Move, Tenant shall require its personnel to pack
items of personal property typically found on desktops and in desk drawers and Tenant shall tag any items which Tenant intends to move itself. With respect to those items of personal property and equipment which Tenant prefers to move itself, Tenant
shall identify such items to Landlord in writing prior to the date upon which the Landlord Move is scheduled to occur and Tenant shall be responsible for moving such items to the 69th Floor Premises prior to the Occupancy Date (“Tenant Move”). Tenant shall be permitted to conduct the Tenant Move at such times during or after
normal business hours and on the weekend as Tenant shall reasonably determine. Tenant shall be responsible for reinstalling and re-connecting its computer and telecommunications equipment in the 69th Floor Premises and Tenant shall coordinate 

  

 3 

 
such work with the Landlord Move to avoid interference with or delay in the completion of the Landlord Move. Any items remaining in the 79th Floor Premises after the Occupancy Date shall be deemed abandoned, and can be disposed of by Landlord at Landlord’s
discretion, with no further liability or responsibility to Tenant therefor. Landlord agrees to pay or, within thirty (30) days after Tenant’s request, reimburse to Tenant, (at Tenant’s election) the direct, actual third party reasonable
expenses of Tenant for (i) the Tenant Move from the 79th Floor Premises to the 69th Floor Premises, (ii) reinstallation of the Tenant’s computers and telecommunications equipment in the 69th Floor Premises, and (iii) replacement of stationery and business cards rendered unusable by such relocation. Landlord agrees to repair damage to ( or
replace if necessary) any personal property or equipment of Tenant damaged in the course of the Landlord Move except if such damage is caused by Tenant, or any of Tenant’s employees, agents or contractors. 
  
 (c) Effective as of the Occupancy Date, the 69th Floor Premises shall be substituted for 79th Floor Premises, and become a part of the Premises, pursuant to and subject to all of the terms, provisions and conditions set forth in the Original Lease,
except as otherwise modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Initial Premises. Exhibit C, attached hereto and
incorporated in this Amendment by this reference, shall be substituted for page 31 of Exhibit “B” attached to the Original Lease. 
  
 (d) Landlord and Tenant hereby acknowledge that the rentable square footage of the 69th Floor Premises has been determined to be Four Thousand Five Hundred Twenty-Five (4,525) rentable square feet. The foregoing notwithstanding, Tenant’s
Base Rent and Additional Rent with respect to the 69th Floor Premises as it exists on the date hereof shall continue
to be as set forth in Exhibit C attached to the Original Lease and calculated on the basis of Three Thousand five Hundred Eleven (3,511) Rentable Square Feet and shall not increase as a result of the relocation from the 79th floor to the 69th floor (but shall continue to increase or decrease as set forth in the Lease). 
  
 (e) Section 42 of the Original Lease, entitled “79th Floor Cancellation Rights”, shall be applicable to the 69th Floor Premises. 
  
 (f) The parenthetical set forth in the first sentence of Section 1(b)(i)(C) is hereby modified and amended by deleting the reference to “79th Floor Premises” and substituting therefor the words “69th Floor Premises”; and 
  
 (g) The parenthetical set forth in the second sentence of Section 1(b)(i)(C) is hereby modified and amended by deleting the words
“the 79th floor,” and substituting therefor
the words “69th floor”.

  
 4. Intentionally Omitted

  
 5. Aon Sublease. Reference is made to that
certain Sublease dated as of July 30, 1999 between Tenant, as Sublessor, and Aon Corporation, a Delaware corporation 

  

 4 

 
(“Aon”), as Sublessee (as the same may be amended, supplemented, renewed and/or restated from time to time, the “Aon Sublease”). The
portion of the Premises which Aon subleases from Tenant under the Aon Sublease from time to time is referred to herein as the “Aon Premises”. Landlord and Tenant hereby agree as follows with respect to the Aon Sublease and the Aon
Premises. 
  
 (i) Landlord will provide those
services which Landlord is required to perform under the Lease with respect to the Aon Premises directly to Aon (any such services are referred to herein as “Aon Services”); and 
  
 (ii) Landlord will provide bills and invoices for Aon
Services directly to Aon (at such address as Tenant shall provide), and simultaneously forward copies of the same to Tenant (in accordance with the notice provisions of the Lease); 
  
 (iii) Landlord will accept payment of bills and invoices for Aon Services directly from either Aon or
Tenant; 
  
 (iv) Landlord will provide copies of
any notices of failure to pay any bill or invoice for Aon Services simultaneously to Aon (at the address specified by Tenant pursuant to clause (ii) above) and Tenant (pursuant to the notice provisions of the Lease); and 
  
 (v) If neither Aon nor Tenant pays for the cost of any Aon
Services as required under the Lease, such failure shall be deemed to be a failure of Tenant to pay for extra or additional services under the Lease. 
  
 6. Donation of Art Work. Landlord agrees to donate to the City of Chicago or such other governmental entity or not-for-profit- corporation
as directed by Tenant the portion of that certain piece of art work, known by the parties as the Bertoia structure (the “Bertoia”), which is located in the southeast and southwest corners of the plaza of the Building, provided that Tenant
donates the portions of the Bertoia that it or any of its affiliates own to the same governmental entity or not-for-profit corporation to which it directs Landlord to donate. Upon Tenant’s written request, which request shall include details of
the arrangements with the City of Chicago regarding the physical relocation of the Bertoia from the plaza of the Building to its new location, Landlord shall remove, or cause to be removed, those portions of the Bertoia from the plaza of the
Building at Tenant’s expense and Tenant agrees to reimburse to Landlord, upon thirty (30) days prior written notice, the costs incurred by Landlord to remove the Bertoia from the Plaza and to restore and landscape the area of the plaza where
the Bertoia was formerly located, including the surrounding area, in a manner consistent with the rest of the plaza. Tenant shall be responsible for relocating the Bertoia from the plaza to the City’s designated location. 
  
 7. Landlord’s Expenses Statement. Landlord shall mail the
Landlord’s Expenses Statement to Tenant at the following address: 28301 Ferry Road, Mail Code MC2W, Warrenville, Illinois 60555, Attention: Mary Hartkopp. Tenant may from time to time upon written notice to Landlord designate a different
address to which the Landlord’s Expenses Statement shall be sent.

 8. Real Estate Brokers. Landlord and Tenant each represent and warrant to the other that it
has not dealt with any broker, agent or finder in connection with this Second Amendment, and that insofar as it knows, no other broker negotiated this Second Amendment or is entitled to any commission in connection therewith. Landlord and Tenant
each agree to indemnify and hold the other, and its employees, agents and affiliates harmless from all damages, judgments, liabilities and expenses (including reasonable attorneys’ fees) arising from any claims or demands of any other broker,
agent or finder with whom it has dealt for any commission or fee alleged to be due in connection with this Second Amendment. 
  
 9. Consent. Landlord and Tenant represent and warrant to each other that it has obtained all of authorizations and consents necessary to
execute and deliver this Second Amendment and that this Second Amendment constitutes the valid, legal and binding obligations of Tenant and Landlord, subject to Tenant obtaining the consent of Aon. 
  
 10. No Offer. The submission and negotiation of this Second
Amendment shall not be deemed an offer to enter the same by Landlord. This Second Amendment shall not be binding until executed by both parties; provided that the execution and delivery of this Second Amendment by Tenant shall constitute an
irrevocable offer by Tenant to amend the Original Lease on the terms and conditions herein contained, which offer may not be withdrawn or revoked for ten (10) days after the execution and delivery of this Second Amendment by Tenant to Landlord.

  
 11. Miscellaneous. This Second Amendment shall
be binding upon and shall muré to the benefit of Landlord and Tenant and their respective beneficiaries, legal representatives, heirs, successors and assigns. Except to the extent amended or modified by this Second Amendment, all other terms,
conditions and provisions of the Lease are, and shall remain, in full force and effect and are hereby ratified and confirmed. This Second Amendment, together with the Original Lease, sets forth the entire agreement between the parties with respect
to the subject matter set forth herein and therein and may not be modified, amended or altered except by subsequent written agreement between the parties. There have been no additional oral or written representations or agreements. In the event that
any provision of this Second Amendment shall be held invalid or unenforceable, such provision shall be severable from, and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of this Second
Amendment. In case of any inconsistency between the provisions of the Original Lease and this Second Amendment, the latter provisions shall govern and control. This Second Amendment may be executed in one (1) or more counterparts, all of which taken
together shall constitute one (1) original document.

 Reference is made to the Lease. All terms used herein, but otherwise not defined, shall have the meaning given to them in the Lease. 
  
 This letter is to inform you that Landlord desires to sell the Building and
the Land. Pursuant to Section 41 of the Lease, this letter shall constitute a Sale Notice to Tenant. If you do not deliver to us an Offer to Purchase the Building and the Land in the next 30 days, you have no further rights under Section 41 of the
Lease. Therefore, in the event that you do not intend to deliver an Offer to Purchase within the next 30 days, we request that you execute and deliver to us the enclosed waiver immediately. Should you have any questions in connection with this
letter, please contact me at (212) 583-5854 or Marshall Findley at (212) 583-5876.

 Reference is made to that Office Lease between BRE/Randolph

waiver but otherwise not defined shall have the meaning given to them in the Lease. Tenant acknowledges receipt of a Sale Notice dated February 19, 2003 (the “Sale Notice”) from Landlord. Tenant hereby waives any and all
rights, now and in the future, to deliver to Landlord an Offer to Purchase in connection with the Sale Notice or claim any rights of first offer pursuant to Section 41 of the Lease.

 Ladies and Gentlemen: 
  
 Reference is made to the Lease. All terms used herein, but otherwise not defined, shall have the meaning given to them in the Lease. 
  
 Landlord sent to you a letter dated February 19, 2003 (the “Notice
Letter”), informing you that Landlord intends to sell the Land and the Building and requesting that you waive any right of first offer you might have under the Lease. Upon further review of the Lease, it has become evident that
Tenant’s right of first offer under Section 41 of the Lease is applicable only if the Tenant Occupancy Requirement is satisfied. As you know, Tenant’s current occupancy is substantially below this required threshold. Therefore, Landlord
has no obligations to Tenant at this time under Section 41 of the Lease and intends to sell the Land and the Building in the near future without further reference to Section 41 of the Lease. As a courtesy to Landlord, we would still appreciate your
execution and delivery of the waiver certificate delivered to you in the Notice Letter. 

 February 21, 2003

 STOCK PURCHASE WARRANT 
  
 To Purchase 187,500 Shares of Common Stock of 
  
 OXiGENE, Inc. 
  
 THIS STOCK PURCHASE WARRANT
CERTIFIES that, for value received, Riverview Group, LLC (the “Holder”), is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after June 10, 2003
(the “Initial Exercise Date”) and on or prior to the close of business on June 9, 2005 (the “Termination Date”) but not thereafter, to subscribe for and purchase from OXiGENE, Inc., a corporation incorporated in the
State of Delaware (the “Company”), up to 187,500 shares (the “Warrant Shares”) of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”). The purchase price of one share of
Common Stock (the “Exercise Price”) under this Warrant shall be $15.00, subject to adjustment hereunder. The Exercise Price and the number of Warrant Shares for which the Warrant is exercisable shall be subject to adjustment
as provided herein. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated June 10, 2003, between the Company and
the investors signatory thereto. 
  

 1 

 1. Title to Warrant. Prior to the Termination Date and subject to compliance with applicable laws
and Section 7 of this Warrant, this Warrant and all rights hereunder are transferable, in whole or in part, to up to 3 Persons in any 12 month period, at the office or agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant together with the Assignment Form annexed hereto properly endorsed. The transferee shall sign an investment letter in form and substance reasonably satisfactory to the Company. 
  
 2. Authorization of Shares. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue). 
  
 3. Exercise of Warrant. 
  
 (a) Except as provided in Section 4 herein, exercise of the purchase rights represented by this Warrant may be made at any time or times
on or after the Initial Exercise Date and on or before the Termination Date by the surrender of this Warrant and the Notice of Exercise Form annexed hereto duly executed, at the office of the Company (or such other office or agency of the Company as
it may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the Company) and upon payment of the Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn
on a United States bank or by means of a cashless exercise pursuant to Section 3(d), the Holder shall be entitled to receive a certificate for the number of Warrant Shares so purchased. Certificates for shares purchased hereunder shall be delivered
to the Holder within three (3) Trading Days after the date on which this Warrant shall have been exercised as aforesaid. This Warrant shall be deemed to have been exercised and such certificate or certificates shall be deemed to have been issued,
and the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company of the Exercise Price and
all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior to the issuance of such shares, have been paid. If the Company fails to deliver to the Holder a certificate or certificates representing the Warrant Shares pursuant to
this Section 3(a) by the close of business on the third Trading Day after the date of exercise, then the Holder will have the right to rescind such exercise. In addition to any other rights available to the Holder, if the Company fails to deliver to
the Holder a certificate or certificates representing the Warrant Shares pursuant to an exercise by the close of business on the third Trading Day after the date of exercise, and if after such third Trading Day the Holder is required by its broker
to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then
the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including 
  

 2 

 brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount
obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (B) the price at which the sell order giving rise to such purchase obligation was
executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored or deliver to the Holder the number of shares of Common Stock that would have
been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of
shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the
Company written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit a Holder’s right to pursue
any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares
of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof. 
  
 (b) If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

  
 (c) Notwithstanding anything herein to the
contrary, in no event shall the Holder be permitted to exercise this Warrant for Warrant Shares to the extent that (i) the number of shares of Common Stock beneficially owned by such Holder, together with any affiliate thereof (other than Warrant
Shares issuable upon exercise of this Warrant) plus (ii) the number of Warrant Shares issuable upon exercise of this Warrant, would be equal to or exceed 4.9999% of the number of shares of Common Stock then issued and outstanding, including
shares issuable upon exercise of this Warrant held by such Holder after application of this Section 3(c). As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated
thereunder. To the extent that the limitation contained in this Section 3(c) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder) and of which a portion of this Warrant is
exercisable shall be in the sole discretion of such Holder, and the submission of a Notice of Exercise shall be deemed to be such Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by such
Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. Nothing contained herein
shall be deemed to restrict the right of a Holder to exercise this Warrant into Warrant Shares at such time as such exercise will not violate the provisions of this Section 3(c). The provisions of this Section 3(c) may be waived by 
  

 3 

 the Holder upon, at the election of the Holder, not less than 61 days’ prior notice to the Company,
and the provisions of this Section 3(c) shall continue to apply until such 61st day (or such later date, as
determined by the Holder, as may be specified in such notice of waiver). No exercise of this Warrant in violation of this Section 3(c) but otherwise in accordance with this Warrant shall affect the status of the Warrant Shares as validly issued,
fully-paid and nonassessable. 
  
 (d) If, but
only if, at any time after one year from the date of issuance of this Warrant there is no effective Registration Statement registering the resale of the Warrant Shares by the Holder, this Warrant may also be exercised at such time by means of a
“cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: 
  
 (A) = the VWAP on the Trading Day preceding the date of such election;

  
 (B) = the Exercise Price of the Warrants, as adjusted; and

  
 (X) = the number of Warrant Shares issuable upon exercise of
the Warrants in accordance with the terms of this Warrant. 
  
 4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price. 
  

5. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer
tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed
by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form
attached hereto duly executed by the Holder; and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. 
  
 6. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the
timely exercise of this Warrant, pursuant to the terms hereof. 
  
 7. Transfer, Division and Combination. 
  
 (a) Subject to compliance with any applicable securities laws and the conditions set forth in Sections 1 and 7(e) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder are transferable,
in whole or in part, upon surrender of this Warrant at the principal office of the Company, together 

  

 4 

 
with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient
to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination
or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be
exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.  
  
 (b) This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together
with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 7(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. 
  
 (c) The Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new
Warrant or Warrants under this Section 7. 
  
 (d)
The Company agrees to maintain, at its aforesaid office, books for the registration and the registration of transfer of the Warrants. 
  
 (e) If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall
not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer (i) that the Holder or transferee of
this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such transfer may be made
without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and
(iii) that the transferee be an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act. 
  
 8. No Rights as Shareholder until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the payment of the aggregate Exercise Price (or by means of a cashless exercise), the Warrant Shares so purchased shall be and be deemed to be issued to such Holder as the
record owner of such shares as of the close of business on the later of the date of such surrender or payment. 
  
 9. Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, 
  

 5 

 and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of
the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate. 
  
 10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday, Sunday or a legal holiday, then such action may be taken
or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday. 
  
 11. Adjustments of Exercise Price and Number of Warrant Shares; Stock Splits, etc. The number and kind of securities purchasable upon the exercise
of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the happening of any of the following. In case the Company shall (i) pay a dividend in shares of Common Stock or make a distribution in shares of Common
Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv)
issue any shares of its capital stock in a reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive
the kind and number of Warrant Shares or other securities of the Company which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. Upon each such adjustment of the kind and number of Warrant
Shares or other securities of the Company which are purchasable hereunder, the Holder shall thereafter be entitled to purchase the number of Warrant Shares or other securities resulting from such adjustment at an Exercise Price per Warrant Share or
other security obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately prior to such adjustment and dividing by the number of Warrant Shares or
other securities of the Company resulting from such adjustment. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

  
 12. Reorganization, Reclassification, Merger, Consolidation
or Disposition of Assets. In case the Company shall reorganize its capital, reclassify its capital stock, consolidate or merge with or into another corporation (where the Company is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of the successor or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Stock of the Company, then the
Holder shall have the right thereafter to receive, at the option of the Holder, (a) upon exercise of this Warrant, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization, 

  

 6 

 
reclassification, merger, consolidation or disposition of assets by a Holder of the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event, or (b) cash equal to the value of this Warrant as determined in accordance with the Black-Sholes option pricing formula. In case of any such reorganization, reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation (if other than the Company) shall expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Company
and all the obligations and liabilities hereunder, subject to such modifications as may be deemed appropriate (as determined in good faith by resolution of the Board of Directors of the Company) in order to provide for adjustments of Warrant Shares
for which this Warrant is exercisable which shall be as nearly equivalent as practicable to the adjustments provided for in this Section 12. For purposes of this Section 12, “common stock of the successor or acquiring corporation” shall
include stock of such corporation of any class which is not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption and shall also include any evidences of indebtedness, shares of
stock or other securities which are convertible into or exchangeable for any such stock, either immediately or upon the arrival of a specified date or the happening of a specified event and any warrants or other rights to subscribe for or purchase
any such stock. The foregoing provisions of this Section 12 shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or disposition of assets. 
  
 13. Voluntary Adjustment by the Company. The Company may at any time during the term of this Warrant reduce the then
current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 
  
 14. Notice of Adjustment. Whenever the number of Warrant Shares or number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company shall give notice thereof to the Holder, which notice shall state the number of Warrant Shares (and other securities or property) purchasable upon the exercise of this
Warrant and the Exercise Price of such Warrant Shares (and other securities or property) after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was
made. 
  
 15. Notice of Corporate Action. If at any time:

  
 (a) the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, or any right to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or 
  
 (b) there shall be any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger of the Company with, or any sale, transfer or other disposition of all
or substantially all the property, assets or business of the Company to, another corporation or, 
  

 7 

 (c) there shall be a voluntary or involuntary dissolution, liquidation or winding up of
the Company; 
  
 then, in any one or more of such cases, the Company shall give to
Holder (i) at least 20 days’ prior written notice of the date on which a record date shall be selected for such dividend, distribution or right or for determining rights to vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii) in the case of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days’ prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause also shall specify (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or
right, the date on which the holders of Common Stock shall be entitled to any such dividend, distribution or right, and the amount and character thereof, and (ii) the date on which any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up is to take place and the time, if any such time is to be fixed, as of which the holders of Common Stock shall be entitled to exchange their Warrant Shares for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding up. Each such written notice shall be sufficiently given if addressed to Holder at the last address of Holder appearing on the books of the Company and delivered in
accordance with Section 17(d). 
  
 16. Authorized Shares.
The Company covenants that during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase
rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates
for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market upon which the Common Stock may be listed. 
  
 Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its
certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against
impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all
such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant. 
  

 8 

 Before taking any action which would result in an adjustment in the number of Warrant Shares for which
this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof. 

 
 17. Miscellaneous. 
  
 (a) Jurisdiction. This Warrant shall constitute a
contract under the laws of New York, without regard to its conflict of law, principles or rules. 
  
 (b) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered,
will have restrictions upon resale imposed by state and federal securities laws. 
  
 (c) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder
shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies, notwithstanding all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any
provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees,
including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder. 
  
 (d) Notices. Any notice, request or other document required or permitted to be given or delivered to
the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement; provided upon any permitted assignment of this Warrant, the assignee shall promptly provide the Company with its contact information.

  
 (e) Limitation of Liability. No
provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant or purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. 
  
 (f) Remedies. Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to
waive the defense in any action for specific performance that a remedy at law would be adequate. 
  
 (g) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby
shall inure to the benefit of and 

  

 9 

 
be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the
benefit of all Holders from time to time of this Warrant and shall be enforceable by any such Holder or holder of Warrant Shares. 
  
 (h) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and
the Holder; provided, however, if this Warrant is subsequently transferred to other Persons, this Warrant may be modified or amended or the provisions hereof waived with the written consent of such transferees (and the original Holder
if such Holder holds any part of the Warrant at such time) holding Warrant(s) exercisable into a majority of the Warrant Shares then issuable under the Warrants derived from the initial Warrant. 
  
 (i) Severability. Wherever possible, each provision
of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant. 
  
 (j) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed
a part of this Warrant.
