 Dear Tom: 
 This letter agreement will set forth the terms of
your employment as Executive Chairman of the Board of Hyatt Hotels Corporation (“Hyatt” or the “Company”) commencing August 1, 2009 (the “Effective Date”), and shall supersede and replace any
prior agreements and understandings between you and Hyatt related to you employment with Hyatt (“Prior Agreements”). 
  

			
	Position:	  	Executive Chairman of the Board.
		
	Board:	  	Prior to the initial public offering of the Company’s common stock (“IPO”), so long as you are a member of the Company’s Board of Directors
(“Board”) you will be appointed as Executive Chairman. Following the IPO, so long as you are a member of the Board of the Company, the Company will use commercially reasonable efforts to appoint you as Executive Chairman as long as
you are willing and able to serve in that office. If you are not re-appointed as Executive Chairman, you will be entitled to terminate your employment with the rights and entitlements available to you under the Company’s Severance Plan (as in
effect and as amended from time to time, the “Severance Plan”) as if your employment was terminated by the Company without Cause.
		
	Reporting:	  	You will report to the Board.
		
	Scope:	  	You will devote sufficient business time and attention to the business and affairs of the Company as reasonably necessary to fulfill your duties and responsibilities hereunder. You will be
permitted to (a) engage in civic, philanthropic or similar activities and teach or speak at educational or civic institutions or organizations, (b) manage your personal affairs and investments, and (c) engage in other business
activities.
		
	Term:	  	From the Effective Date through December 31, 2012. Notice by the Company or you to extend the term of your employment with the Company beyond December 31, 2012 must be delivered to the other
party in writing

			
		  	on or before June 30, 2012. Any agreement to extend the term of your employment with the Company will set forth the terms and conditions of any such extension and executed by you and on
behalf of the Company.
		
	Base Salary:	  	From and after August 1, 2009, your base salary will be $475,000 on an annualized basis (payable in accordance with the Company normal payroll of base salary to senior executives), less
required tax and other authorized withholdings. Your salary will be reviewed annually by the Compensation Committee of the Board (the “Committee”) and may be increased at their discretion.
		
	Annual Equity Participation:	  	For the 2010 year and thereafter, you will be eligible for annual grants under the Amended and Restated Global Hyatt Long Term Incentive Plan (as amended and restated from time to time,
“LTIP”) grants similar to other senior executives of Hyatt; provide that all LTIP grants for services relating to calendar year 2012 shall be made no later than December 31, 2012, unless the term of your employment with the Company
is extended beyond December 31, 2012 as provided above. Such annual LTIP grants currently take the form of stock appreciation rights (“SARs”) and/or restricted stock units (“RSUs”) and vest pro rata annually over
the vesting period determined by the Committee (as Administrator of the LTIP), however, in the future such vesting may be, in part, performance based as determined by the Committee. Beginning with calendar year 2010, your annual grants will be
targeted to have a grant date fair value (as determined under FAS 123R) equal to 500% of your base salary.
		
	LTIP:	  	 All SAR and RSU grants, whether annual or supplemental, will be subject to the terms and conditions set forth in the LTIP (including the class of
shares available) and the applicable award agreements approved by the Committee; provided that to the extent your employment with the Company terminates for any reason other than cause (as defined in the Severance Plan) prior to full vesting of any
of your LTIP awards, such awards will continue to vest and be exercisable and payable as if your employment continued so long as you (a) provide a general release of claims against the Company in such form as the Company may reasonably require and
(b) you do not engage in Competition (as defined below). If you do not provide a general release of claims against the Company, you revoke or violate such release or you engage in Competition with the Company, then you will forfeit any LTIP awards
which were not vested upon your termination of employment.
  
 For this purpose
“Competition” shall mean the provision of services as an employee, contractor, director, advisor, or in any other capacity, or ownership, directly or indirectly for or with a Competitor, as determined in the sole discretion of the
Committee; provided, however, you will not be deemed to be engaged in Competition by reason of your ownership of less than 5% of any public company that is a Competitor, whether directly or

  

 2 

			
		  	 indirectly. A “Competitor” shall mean any enterprise a principal business of which is the ownership, management and/or development
of hotels, resorts and/or timeshares and fractional properties in any geographic area in which the Company is then conducting or planning to conduct such business, and which actively competes with the Company for customers, as determined in the sole
discretion of the Committee.
  
 To the extent that Hyatt’s common stock is not
publicly traded, any shares of Hyatt common stock received upon exercise of the SARs or upon settlement of the RSUs will be subject to the terms and conditions, including transfer restrictions, set forth in the Amended and Restated
Stockholders’ Agreement applicable to LTIP participants (as amended from time to time).

		
	Benefits:	  	 As an employee of Hyatt you will receive the following benefits at the level and under terms which, in the aggregate are substantially equivalent to
those provided from time to time to the Company’s senior executive officers generally:
  
 •        Medical and Dental insurance
  
 •        Life
Insurance
  
 •        401(k) and Retirement Savings Plan
  
 •        Disability Coverage
  
 •        Vacation benefits
  
 •        Automobile lease in accordance with Hyatt’s policies for
officers
  
 •        Monthly parking in Hyatt Center
  
 •        Executive Dining Room privileges for you and your business
guests
  
 •        Deferred Compensation Plan
  
 •        Executive Medical Plan
  
 All our benefit plans and programs are subject to change or termination at any time at the
discretion of the Committee or the Board.

		
	 Termination;
 Severance;
 Change of
 Control:
	  	Upon termination of your employment with the Company your rights to any severance will be determined under the Severance Plan (or, if applicable, the Company’s Change in Control Plan, as in
effect and as amended from time to time (the “CiC Policy”)) applicable to your position, if any, as in effect at such time.
		
	 Restrictive
 Covenants:
	  	You will be bound by the restrictive covenants set forth in your LTIP award agreements and in your Confidentiality, Intellectual Property, Non-Solicitation and Non-Disparagement Agreement
(“CIPN&N Agreement”).

  

 3 

			
	Legal Costs:	  	You will be responsible for any legal costs associated with this letter agreement.
		
	Indemnification:	  	You shall be indemnified to the maximum extent provided under the indemnification provisions for officers and directors of the Company set forth in the Company’s Certificate of
Incorporation and Bylaws.
		
	Other:	  	As a condition of your continued employment with Hyatt, you confirm that you have signed or will agree to execute to a CIPN&N Agreement and the Company’s Code of Business Conduct and
Ethics. In addition, you will be bound by all company policies to the extent that they apply to senior executives of the Company, including, the T&E Policy, the Internet Use Policy, the Compensation Recovery Policy, the Share Ownership
Guidelines, the Severance Plan and the CiC Policy.

 Please note that your employment at Hyatt is “at will.” This means that you may resign from Hyatt at any
time with or without cause, and Hyatt has the right to terminate your employment with or without cause at any time subject to the terms of any Company polices applicable to your position at the time of termination, including, without limitation, the
Severance Policy and the CiC Policy. Neither this letter agreement nor any other communication, either written or oral, should be construed as a contract of employment for any particular duration. This letter agreement supersedes and replaces all
prior written and oral communication on employment related subjects, including any Prior Agreements.

 Please sign and date this letter agreement in the space indicated and return it to my attention to evidence your
understanding and agreement to the terms set forth herein. 
 Sincerely,

 (C) Rentable Area. 
 (i) For purposes of this Lease, “Rentable Area” shall mean in respect of any space, the rentable area or the sum of the
rentable areas of such space determined in accordance with the methods of measuring and determining rentable area and usable area set forth in The Standard Method for Measuring Floor Area in Office Buildings ANSI Z65.1-1996, as promulgated by The
Building Owners and Managers Association (BOMA) International (the “Standard Method”); provided, however, 
  

	 	(1)	   

  

	 	(a)	If the R/U Ratio (as such term is defined in such Standard Method) of any portion of the Premises that comprises a full floor of the Building exceeds 110% then the Rentable Area of
such portion of the Premises shall be deemed to equal 110% of the Usable Area (as such term is defined in such Standard Method) of such portion of the Premises; 

  

	 	(b)	If the R/U Ratio of the Fitness Center Space and the Cafeteria Space, taken together, exceeds 110% then the Rentable Area of each of the Fitness Center Space and the Cafeteria Space
shall be deemed to equal 110% of the Usable Area thereof (it being understood that the aggregate Rentable Area of the Fitness Center Space and the Cafeteria Space comprises all of the Rentable Area on the floor on which such spaces are located).

  

	 	(2)	If the Rentable Area, as computed in accordance with the Standard Method as modified, if applicable, by subparagraph (1) above (the “Actual Rentable Area”), of
the portion of the Premises located on any floor of the Building shall exceed 103% of the Rentable Area thereof as set forth in Paragraph 1(A), then the Rentable Area of such portion of the Premises shall be deemed for all purposes of this
Lease to equal 103% of the Rentable Area thereof set forth in Paragraph 1(A); 

  

	 	(3)	If the Actual Rentable Area of the Fitness Center Space and the Cafeteria Space taken together shall exceed 103% of the Rentable Area thereof as set forth in Article 7 then the
Rentable Area of the Fitness Center Space and the Cafeteria Space shall be deemed for all purposes of this Lease to equal 103% of the Rentable Area thereof as set forth in Article 7; 

  

 5 

	 	(4)	The Rentable Area of the Building (a) shall not include the basement level space or any portions of the Building which are designed to be used for parking or storage in the
parking garage, and (b) shall include the Rentable Area of the Circulation Area; and 

  

	 	(5)	The Rentable Area of the Circulation Area shall be deemed for all purposes of this Lease to be equal to the Usable Area of the Circulation Area. 

 The aforesaid Standard Method, as modified by sub-subparagraphs (1), (2), (3) (4) and (5) above, is herein called the “Measurement
Method”. 
 (ii) Promptly after the substantial completion of the Landlord’s Work, Landlord shall cause its
architect to actually measure and, using the Measurement Method, to compute the Rentable Area of the Building and each floor thereof, and to furnish Tenant with copies of the results of such measurements and of such computations
(“Landlord’s Measurement Report”). Tenant shall have the right, within sixty (60) days of its receipt of Landlord’s Measurement Report, to measure the Building and/or any floor thereof and to dispute Landlord’s
Measurement Report. Any such dispute not resolved within thirty (30) days of Tenant’s notice shall be resolved by an independent architect chosen by the parties, or if within five (5) days of the request of either party, they fail to
make such choice, then by an architect designated by the American Arbitration Association. The term “Final Measurement Report” shall mean (a) if Tenant shall timely have disputed Landlord’s Measurement Report,
Landlord’s Measurement Report as modified to reflect the results of such dispute, or (b) otherwise, Landlord’s Measurement Report. The Final Measurement Report shall be used for all purposes of this Lease, including (a) the
determination of the Rentable Area of the Premises, the Fitness Center Space, the Cafeteria Space, the Circulation Area and any portions of the Building included in the Premises pursuant to Article 35 (and the Rentable Areas set forth therein
shall supersede any different Rentable Areas set forth in this Lease), (b) the determination of Net Rent and Tenant’s Pro Rata Share of Operating Expenses and Taxes, and (c) the determination of Additional Rent payable by Tenant
pursuant to Paragraph 3(G). Promptly after the lapse of Tenant’s right to dispute, or the resolution of any dispute timely commenced with respect to, Landlord’s Measurement Report, the parties shall execute a supplement to this Lease
confirming the determinations set forth in such Final Measurement Report and to which the Final Measurement Report shall be attached. The Final Measurement Report shall be conclusive and binding upon Landlord and Tenant absent manifest error.

 ARTICLE 2. 
 Net
Rent 
 Tenant shall pay to Landlord base net rent with respect to the Mid-Rise Premises beginning on the Mid-Rise Rent Commencement
Date and continuing throughout the Term of this Lease in accordance with the Net Rent schedule attached hereto as Part A of Exhibit B-1 and as otherwise provided herein. Tenant shall pay to Landlord base net rent with respect to the
High-Rise Premises beginning on the High-Rise Rent Commencement Date and continuing throughout the Term of this Lease in accordance 

  

 6 

 
with the Net Rent schedule attached hereto as Part B of Exhibit B-1 and as otherwise provided herein. As used herein, “Net Rent”
means the base net rent payable by Tenant to Landlord with respect to the Premises. Net Rent shall be payable in monthly installments, each installment being payable in advance promptly on the first day of each and every calendar month, except that
if either the Mid-Rise Rent Commencement Date or the High-Rise Rent Commencement Date (or both) occurs on a date other than the first day of a month, Tenant shall pay the installment due for such initial fractional month or months on the Mid-Rise
Rent Commencement Date or the High-Rise Rent Commencement Date, as applicable. If the Tenant’s obligation to pay Net Rent with respect to any portion of the Premises commences on a day other than the first day of a calendar month, or ends on a
day other than the last day of a calendar month, then the Net Rent with respect to such portion of the Premises for such month shall be prorated on the basis of the applicable percentage of the monthly Net Rent represented by each day of such month.
Net Rent shall be paid without any prior demand or notice therefor and without any deduction, set-off or counterclaim, or relief from any valuation or appraisement laws, except to the extent expressly provided to the contrary in this Lease.

 ARTICLE 3. 
 Additional Rent 
 (A) Taxes. Tenant shall pay Landlord an amount equal to Tenant’s Pro Rata Share of
Taxes in the manner described below, commencing on the Mid-Rise Rent Commencement Date and continuing throughout the Term of this Lease in accordance with this Article 3. 
 “Taxes” shall mean all federal, state, county, or local governmental or municipal taxes, fees, assessments, charges or other impositions
of every kind and nature, whether general, special, ordinary or extraordinary (including, without limitation, real estate taxes, general and special assessments (provided that all assessments shall be treated as payable over the longest permitted
period, and in such event shall include any interest charged by or payable to the applicable governmental authority in connection therewith), transit taxes, taxes based upon the receipt of rent including gross receipts or sales taxes applicable to
the receipt of rent (but rent from tenants in the Building shall be treated as the only rent received by Landlord), or service, lease or value added taxes (provided that if such rent tax, sales tax, service tax, or value added tax is required by
Article 17 to be paid by Tenant then any such tax with respect to Tenant and all other tenants of the Building shall be excluded), personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, furniture and other personal
property owned and used by Landlord solely in connection with the Property) which shall be payable by Landlord during any calendar year (as reflected in the tax bills due and payable in such year), any portion of which calendar year occurs during
the Term after the Rent Commencement Date (without regard to any different fiscal year used by such government or municipal authority and notwithstanding that any of such items may be assessed, imposed or otherwise accrue in a different calendar
year) because of or in connection with Landlord’s ownership, leasing and/or operation of the Property or the personal property, fixtures, machinery, equipment, systems and apparatus located therein and used solely in connection therewith.
Notwithstanding the foregoing, there shall be excluded from Taxes all excess profits taxes; franchise taxes; gift taxes; capital stock taxes; inheritance and succession taxes; transfer taxes; mortgage or intangible taxes; fees or assessments for

 7 

 
imposed upon Landlord in connection with the initial development or construction of the Building or the Property; estate taxes; federal, state and local
income taxes; fines, penalties and interest due to the late payment by Landlord of Taxes (so long as Tenant timely paid to Landlord Tenant’s Pro Rata Share of Taxes as hereinafter provided); and other taxes to the extent applicable to
Landlord’s general or net income (as opposed to taxes specific to rents, receipts or income attributable to ownership or operation of real property). Should the State of Illinois, or any political subdivision of that state or any other
governmental authority having jurisdiction over the Land or the Building impose 
 (a) a tax, assessment, charge, or fee, or
increase a then-existing tax, assessment, charge, or fee, that Landlord shall be required to pay, by way of substitution for real estate taxes and ad valorem personal property taxes or in addition to real estate taxes and ad valorem personal
property taxes, because of or in connection the Landlord’s ownership, leasing, and/or operation of the Property or the personal property, fixtures, machinery, equipment, systems and apparatus located therein and used solely in connection
therewith, or 
 (b) an income, franchise or other tax, assessment, fee or charge, on gross rents or receipts from the
Property (but only to the extent rent and receipts from tenants in the Building is treated as the only rent received by Landlord), in substitution for or as a supplement to a tax levied against the Property or the personal property used in
connection therewith, 
 all such taxes, assessments, fees or charges, to the extent same are not excluded pursuant to the immediately preceding sentence,
shall be deemed to constitute “Taxes” under this Lease. Any reasonable expenses (including, without limitation, all reasonable fees for consultants and attorneys) paid by Landlord to third parties in planning or attempting to
protest, reduce, limit any increase in or otherwise minimize Taxes, or in responding or planning responses to assessment or other notices in respect thereof, shall be included in Taxes in the calendar year such expenses are paid. 
 Tenant shall pay Tenant’s Pro Rata Share of Taxes whether Taxes are increased as a result of increases in the assessment or valuation of the
Property, increases in the tax rates, reduction or elimination of any rollbacks or other deductions available under current law, scheduled reductions of any tax abatement, as a result of the elimination, invalidity or withdrawal of any tax
abatement, or for any other cause whatsoever. Notwithstanding anything herein to the contrary, Landlord agrees that at no time shall Landlord collect from tenants of the Building more than 100% of the Taxes actually incurred by Landlord. 

If Taxes paid during any calendar year of the Term shall be decreased or refunded to Landlord in whole or in part for any reason whatsoever, then
Landlord shall promptly refund to Tenant Tenant’s Pro Rata Share (for the year to which such decrease or refund relates) of such decrease or refund (allocated in the case of special assessments to the applicable portion of the Term) or, if the
Term has not expired, credit such refund to Tenant. 
  

 8 

 If Taxes for any calendar year of the Term shall be increased after payment thereof by Landlord for any
reason including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord within thirty (30) days after receipt of invoice therefor Tenant’s Pro Rata Share (for the year to
which such increase relates) of such increased Taxes. 
 (B) Operating Expenses and Shared Facilities Costs. 
 (i) Tenant shall pay Landlord, in the manner described below, an amount equal to (a) Tenant’s Pro Rata Share of Operating
Expenses, commencing upon the Rent Commencement Date, (b) Tenant’s SFC Share of the Net Shared Facilities Costs allocable to the Fitness Center, commencing on the Fitness Center Commencement Date, and (c) Tenant’s SFC Share of
the Net Shared Facilities Costs allocable to the Cafeteria, commencing on the Cafeteria Commencement Date. 
 (ii)
“Operating Expenses” shall mean all expenses, costs and amounts (other than Taxes) of every kind and nature which shall accrue or be payable by Landlord in respect of any calendar year all or any portion of which occurs during the
Term after the Rent Commencement Date which is properly chargeable in accordance with the Accounting Principles, because of or in connection with the management, repair, maintenance and operation of the Property (subject to the exclusions and other
provisions of this Lease) including, without limitation, any amounts which accrue or are paid for: (a) utilities for the Property, including, but not limited to, electricity, power, gas, steam, oil or other fuel, water, sewer, lighting,
heating, air conditioning and ventilating, (b) permits, licenses and certificates necessary to operate, manage and lease the Property, excluding any required to construct the Building or initially occupy the Premises, (c) insurance
applicable to the Property, not limited to the amount of coverage Landlord is required or permitted to provide under this Lease, (d) supplies, tools, equipment and materials used in the operation, repair and maintenance of the Property,
(e) accounting (but excluding any fees the property management company may charge for accounting services it may perform), legal, inspection, consulting, concierge and other services, (f) any equipment rental (or costs incurred under
equipment installment purchase or equipment financing agreements) for janitorial or similar equipment, (g) management fees and fair rental value of any space devoted to management and not leasing (provided that the amount of management fees
included in Operating Expenses shall not exceed two and one-half percent (2 1/2%) of the annual net rent (i.e., excluding rent in respect of operating expenses, taxes or services) payable by tenants and occupants of the Building), (h) wages,
salaries and other compensation and benefits for all persons directly engaged in the operation, maintenance or security of the Property, and employer’s social security taxes, unemployment taxes or insurance, and any other taxes which may be
levied on such wages, salaries, compensation and benefits, (i) operation, repair, and maintenance of all systems and equipment and components thereof (including non-capital replacement of components), (j) janitorial service, alarm and
security service, window cleaning, trash removal, elevator maintenance, cleaning of walks, parking facilities and building walls, removal of ice and snow, (k) replacement of wall and floor coverings, and light bulbs in lobbies, corridors,

 9 

 
according to generally accepted accounting principles consistently applied (“GAAP”) as modified to conform to the provisions of this Lease
(GAAP, as so modified, is herein called the “Accounting Principles”). As used herein, the phrase “comparable office buildings in the downtown Chicago area” or words of similar import shall mean “Class
A,” high rise office buildings occupied by more than one tenant, containing at least 750,000 square feet of rentable area, and located within a one-half mile radius of the Property. 
 (iii) Notwithstanding the foregoing, Operating Expenses shall not include:

	 	(g)	costs for relocating tenants; 

  

	 	(h)	costs attributable to retail areas in excess of the corresponding amounts which would have been incurred had such areas been used for office purposes (except that, the costs of

	 	(ee)	fines, penalties, interest or surcharges incurred by Landlord on account of the failure to comply with any Law, the failure to make any payment of Operating Expenses when due, or

Operating Expenses; 

  

	 	(ff)	expenditures for repairs or maintenance which are covered and reimbursed by warranties, guarantees or service contracts;

	 	(ll)	costs incurred by Landlord in connection with the maintenance and operation of the garage portion of the Building or the repair of any equipment used in connection with the
operation thereof (but if any agreement shall cover both the garage and office portions of the Building, this clause (ll) shall not be deemed to exclude the portion of the costs thereunder equitably allocable to the office portions of the
Building as reasonably determined by Landlord; 

  

	 	(mm)	costs related to management of the Building which, under a market-based management agreement with an unaffiliated management company providing for a management fee at the rate

	 	(nn)	permits, licenses and fees related to the initial development of the Building and required as a condition to the initial occupancy of the Building; or 

  

	 	(oo)	costs of insurance against loss of or damage to any improvements in tenantable spaces made by or on behalf of or for any tenant of the Building. 

  

	 	(2)	 costs of “capital improvements and other capital items,” as those terms are used in accordance with Accounting Principles, except that Operating
Expenses shall include the cost during the Term (as annuitized (using an interest rate (the “Capital Interest Rate”) equal to the greater of (i) 10 percent per annum or (ii) one percent (1%) over the corporate base
rate of interest of Bank One, N.A., or any successor, at the time such capital improvement or other 

  

 15 

	 	 
capital item is placed in service) over the useful life (for accounting and not tax purposes) of the applicable capital improvement or other capital item) of
any capital improvement, the installation work for which commenced after the Mid-Rise Rent Commencement Date or any other capital item incurred after the Mid-Rise Rent Commencement Date, which improvement or item is intended to reduce Operating
Expenses or to comply with any Law first enacted or promulgated after the Mid-Rise Rent Commencement Date. The amount so included in Operating Expenses for any year on account of any such improvement or item shall not exceed Landlord’s
reasonable calculation of annual savings in Operating Expenses achieved by such improvement or item. For purposes of this Lease, “Laws” shall mean all applicable federal, state, county and local governmental and municipal laws,
statutes, ordinances, rules, regulations, codes, decrees, orders and other such requirements, applicable decisions by courts in cases where such decisions are considered binding precedents in the state in which the Property is located, and decisions
of federal courts applying the Laws of such State. For purposes of this Lease, the term “annuitized” with respect to any sum shall mean converting such sum into a series of equal monthly payments (including interest and principal)
in the manner of a traditional fixed-rate self-liquidating single-family mortgage loan. As an example, for a capital item costing $1000, having a useful life of five years, placed in service when the applicable base rate was 9% per annum (and
thus the applicable rate to be used in the annuitization is 10% per annum) the fixed monthly amount for the entire five year period would be $21.25 per month. 

 (iv) All Operating Expenses shall be net of all discounts and rebates actually received by Landlord. There shall be no duplication of
costs or reimbursements. 
 (v) If the Property is less than 100% occupied during all or a portion of any calendar year, or if
any of the tenants of the Building provide their own services which otherwise would be provided by Landlord and included in Operating Expenses, the amount of those Operating Expenses which vary with occupancy shall be increased for such calendar
year to the amount that would have been paid or incurred had the Property been 100% occupied and had all of the tenants obtained such services from Landlord. In no event, however, shall Landlord collect from tenants of the Building more than 100% of
the Operating Expenses actually incurred by Landlord in operating the Building during each respective calendar year by virtue of the foregoing gross-up or any other reason. For purposes of this subparagraph, the Rentable Area of the Shared
Facilities shall be included for purposes of determining the occupied Rentable Area of the Building. 
 (vi) Shared Facilities
Costs and Shared Facilities Income. 
  

 16 

	 	(1)	The term “Shared Facility” shall mean the Cafeteria or the Fitness Center, and the term “Shared Facilities” shall mean both the Cafeteria and the
Fitness Center. 

  

	 	(2)	The term “Shared Facilities Costs” shall mean, relative to a Shared Facility, the costs of management, repair, maintenance and operation of such Shared Facility, to
the extent such costs exceed the costs (the “Normal Office Costs”) which would have been incurred if the premises constituting the Shared Facility had not been used for a fitness center or a cafeteria but had instead been used for
general office purposes (it being agreed that such Normal Office Costs shall constitute Operating Expenses includable under Paragraph 3(B)(ii) above), but excluding any such costs that are payable by managers, operators, concessionaires and
licensees and are not payable by Landlord. 

 For purposes of illustration only, 
  

	 	(a)	HVAC for the Shared Facilities during Regular HVAC Hours shall be included in Operating Expenses and HVAC for the Shared Facilities outside of Regular HVAC Hours shall be included
in Shared Facilities Costs, and 

  

	 	(b)	if Landlord shall provide cleaning or trash removal service to the Shared Facilities then (i) the costs thereof, up to the cost of cleaning or trash removal which would have
been incurred if the Shared Facilities had not been used for a fitness center or a cafeteria but had instead been used for general office purposes shall be included in Operating Expenses and (ii) the balance of such costs shall be included in
Shared Facilities Costs; 

  

	 	(c)	if the operator, licensee or concessionaire shall provide cleaning or trash removal to the Shared Facilities then Operating Expenses and Shared Facilities Income shall each be
increased by the costs which Landlord would have incurred if the Shared Facilities had not been used for a fitness center or a cafeteria but had instead been used for general office purposes; and 

  

	 	(d)	the cost of electricity provided to the Shared Facilities shall be excluded from Operating Expenses and included in Shared Facilities Costs. 

  

 17 

	 	(3)	Shared Facilities Costs shall not include 

  

	 	(a)	any costs covered by clause (a), (b), (q) [unless authorized by Majority Instrument], (w), (y), and (cc) of Paragraph 3(B)(iii)(1), or 

  

	 	(b)	any capital improvement or other capital item unless the same (i) is required in order for Landlord to perform its obligations under this Lease, or (ii) is approved by
Majority Instrument. 

  

	 	(4)	The term “Shared Facilities Income” shall mean, relative to a Shared Facility, all revenue of any kind received or derived from such Shared Facility, including
membership fees, sundry charges, charges for special services, food and beverage revenue, catering revenue, revenue from reserved use of the Cafeteria and all other sums received from any source, except for revenue that is payable to or otherwise
received and retained by managers, operators, concessionaires and licensees and not paid to Landlord. 

  

	 	(5)	The term “Net Shared Facilities Costs” shall mean, relative to a Shared Facility, the excess, if any, of (a) the Shared Facilities Costs relative to such
Shared Facility, over (b) the Shared Facilities Income relative to such Shared Facility. If the Shared Facilities Income relative to such Shared Facility shall exceed the Shared Facilities Costs relative to such Shared Facility, the Net Shared
Facilities Costs relative to such Shared Facility shall be zero and the provisions of Paragraph 3(H) shall be applicable. 

 (vii) The term “Tenant’s Pro Rata Share” shall mean the percentage determined by dividing (1) the sum of (a) the then Rentable Area of the Premises, plus (b) Tenant’s
SFR Share of the Rentable Area of the Shared Facilities, plus (c) Tenant’s SFR Share of the Rentable Area of the Circulation Area, by (2) the Rentable Area of the Building. Appropriate adjustments shall be made in calculating
Tenant’s Pro Rata Share on a per diem basis in the year in which the Mid-Rise Rent Commencement Date and the High-Rise Rent Commencement Date occur and if, at any other time, the Rentable Area of the Premises or the Rentable Area of the
Building changes during any calendar year as a result of the expansion or contraction of the Premises or Building, so long as Tenant’s liabilities or obligations are not increased as a result of any expansion or contraction of the Building, or
if Tenant’s SFR Share changes during any calendar year pursuant to Paragraph 7(C). 
 (C) Manner of Payment of Operating Expenses,
Net Shared Facilities Costs and Taxes. 
 (i) Landlord shall estimate at least sixty (60) days in advance of the Rent
Commencement Date and thereafter at least sixty (60) days in advance of each subsequent calendar year, the amounts Tenant shall owe for Operating Expenses and Net Shared Facilities Costs for the ensuing full or partial calendar year and shall
furnish to Tenant for its review and comment a proposed operating budget for each such calendar year setting forth Landlord’s estimate of Operating Expenses and Net Shared Facilities 

  

 18 

 
Costs for such calendar year. Within thirty (30) days of its receipt of such proposed operating budget, Tenant may advise Landlord of any comments
Tenant has with respect to such proposed operating budget. Landlord, with reasonable promptness, and in reasonable detail, shall respond thereto, and, if requested by Tenant, have representatives of Landlord knowledgeable with respect to the
proposed budget meet with representatives of Tenant to address Tenant’s comments. Landlord shall consider all of Tenant’s comments in good faith, but (except for comments relative to the budget for the Shared Facilities which are made by
Majority Instrument and are consistent with Landlord’s obligations under Article 7), Landlord shall not be required to accept such comments. Tenant’s commenting on or failing to comment on the proposed operating budget or any item
therein, or the outcome of any discussions based thereon, shall not constitute a waiver of or otherwise limit or affect Tenant’s right to contest or object to any item or amount thereof not permitted to be included in Operating Expenses or
Shared Facilities Costs hereunder. Following Landlord’s consideration of and response to Tenant’s comments and, if requested, the meeting with Tenant’s representatives (or, if Tenant does not comment on or request a meeting with
respect to the proposed operating budget within thirty (30) days of its receipt thereof, then following such 30-day period), Landlord shall furnish to Tenant a budget incorporating such revisions as Landlord shall elect (or be required by
Majority Instrument consistent with Landlord’s obligations under Article 7) to make in the previously prepared proposed operating budget and a final statement of the estimated amount of Operating Expenses and Net Shared Facilities Costs
for such ensuing calendar year based on such operating budget. In such event, Tenant shall pay such estimated amounts on a monthly basis, on or before the first day of each calendar month, together with Tenant’s payment of Net Rent. Such
estimate may be adjusted from time to time by Landlord within a calendar year, but, with respect to Operating Expenses, not more frequently than twice in each calendar year, and any such adjustments of estimates within a calendar year shall be based
on Landlord’s reasonable expectations. If any estimate shows an increase in Tenant’s estimated payments for the current calendar year, Tenant shall pay the difference between the new and former estimates, for the period from January 1
of the current calendar year through the month in which such estimate is sent. Tenant shall make such payments within thirty (30) days after Landlord sends the estimate to Tenant. 
 (ii) Tenant shall pay to Landlord (or as directed by Landlord in writing) Tenant’s Pro Rata Share of each installment of Taxes for
each year during the Term after the Mid-Rise Rent Commencement Date within the later of: (a) fifteen (15) days of delivery by Landlord to Tenant of a statement setting forth the amount of each semi-annual (or other required) installment of
Taxes for each year during the Term after the Mid-Rise Rent Commencement Date then due and payable and Tenant’s Pro Rata Share thereof, accompanied by a copy of the tax bill to which it relates, and (b) fifteen (15) days prior to the
date set forth as the due date in the relevant tax bill. Landlord agrees to pay all Taxes when due and owing to the applicable governmental authority, except to the extent Tenant has theretofore failed to pay to Landlord Tenant’s Pro Rata Share
of Taxes in a timely manner as set forth above. 
  

 19 

 (iii) Within 547 days after the end of each calendar year, Landlord shall provide to
Tenant a statement (a “Statement”) certified by an independent, reputable accounting firm with offices in Chicago, Illinois, showing: 
  

	 	(1)	the amount of Operating Expenses, Shared Facilities Costs and Shared Facilities Income for such calendar year, in each case detailing major categories thereof,

  

	 	(2)	the amount paid by Tenant toward Operating Expenses and Net Shared Facilities Costs allocable to said calendar year on an estimated basis pursuant to clause (i) above, and

  

	 	(3)	any revised estimate of Tenant’s obligations for Operating Expenses and Net Shared Facilities Costs for the then-current calendar year, 

  

	 	(4)	the amount of Taxes, including a copy of all bills for Taxes payable by Landlord for such calendar year, and 

  

	 	(5)	the amount paid by Tenant toward Taxes allocable to said calendar year pursuant to clause (ii) above. 

 (iv) If the Statement for any calendar year shows that Tenant’s estimated payments on account of Operating Expenses and Net Shared
Facilities Costs were less than Tenant’s actual obligations on account of Operating Expenses and Net Shared Facilities Costs for such year then, provided that such Statement was furnished within the aforesaid 547 day period, Tenant shall pay
the difference within thirty (30) days after its receipt of the Statement. If the Statement for any calendar year shows that Tenant’s estimated payment on account of Operating Expenses and Net Shared Facilities Costs exceeded Tenant’s
actual obligations on account of Operating Expenses and Net Shared Facilities Costs for such year, Landlord shall refund the difference; provided however, that if this Lease shall not have terminated, Landlord may credit such difference against Rent
hereunder. Any such refund or credit shall be made within 30 days of Landlord’s delivery of the Statement. 
 (v) If the
Statement for any calendar year shows that Tenant’s payments of Taxes under clause (ii) above were less than Tenant’s actual obligations for Taxes for such year then, provided that such Statement was furnished within the aforesaid 547
day period, Tenant shall pay the difference within thirty (30) days after its receipt of the Statement. If any Statement shows that Tenant’s payment of Taxes under clause (ii) above exceeded Tenant’s actual obligations for Taxes,
Landlord shall refund the difference; provided however, that if this Lease shall not have terminated, Landlord may credit such difference against Rent hereunder. Any such refund or credit shall be made within 30 days of Landlord’s delivery of
the Statement. 
  

 20 

 (vi) Tenant’s obligations relative to Taxes, Operating Expenses and Net Shared
Facilities Costs for any calendar year, and Landlord’s obligation to refund to Tenant any overpayment on account thereof, shall survive the expiration or sooner termination of this Lease, subject to clause (viii) below. 
 (vii) In no event shall a decrease in the Taxes, Operating Expenses or Net Shared Facilities Costs decrease the monthly Net Rent payable
hereunder, except for any credits provided for in clauses (iv) and (v) above. 
 (viii) Notwithstanding anything to
the contrary contained in this Article, Tenant shall only be obligated to make payments for Operating Expenses, Net Shared Facilities Costs or Taxes for any calendar year which are included in the Statement for such calendar year and only if such
Statement is furnished within the 547 day period provided for in clause (iii) above, Tenant however, shall remain liable for Tenant’s Pro Rata Share for any increase in Taxes as provided in the last paragraph of Paragraph 3(A). 

(D) Contest of Taxes. Landlord shall use commercially reasonable efforts to minimize Taxes; provided, however, that Landlord shall not be
required to institute any administrative or legal proceeds if it has been advised in writing by a professional tax consultant that such administrative or legal proceeds would not be worthwhile or advisable. The costs of Landlord’s efforts to
minimize Taxes shall be included in Taxes. 
 (E) Proration. If the Mid-Rise Rent Commencement Date or the High-Rise Rent Commencement
Date, the Fitness Center Commencement Date, or the Cafeteria Commencement Date occurs other than on January 1, or the Expiration Date occurs other than on December 31, Tenant’s obligations to pay amounts toward Taxes, Operating
Expenses, Net Shared Facilities Costs relative to the Fitness Center or Net Shared Facilities Costs relative to the Cafeteria, shall be prorated to reflect the portion of such years after or before such date, as the case may be. Such proration shall
be made by multiplying the total estimated or actual (as the case may be) Taxes, Operating Expenses, Net Shared Facilities Costs relative to the Fitness Center or Net Shared Facilities Costs relative to the Cafeteria payable during or for, as the
case may be, such calendar years by a fraction, the numerator of which shall be the number of days from and after such Mid-Rise Rent Commencement Date, the High-Rise Rent Commencement Date, such Fitness Center Commencement Date, or such Cafeteria
Commencement Date or from and before such Expiration Date, as applicable, and the denominator of which shall be 365 (or 366 during any leap year). 
 (F) Landlord’s Records. Landlord shall maintain in the greater Chicago metropolitan area all of the books and records respecting Taxes, Operating Expenses, Shared Facilities Costs and Shared Facilities Income, including all such
books and records created by its managing agent, fitness center operator or cafeteria operator (“Records”) for any calendar year until the fifth anniversary of the last day of such calendar year and, if any dispute with respect to
such calendar year is then pending, until such dispute is resolved. If Tenant, by notice (a “Records Examination Request”) to Landlord given within ninety (90) days of Tenant’s receipt of the Statement for any calendar
year, shall so elect, then Tenant or its representative shall have the right to examine the Records and to meet with the individuals responsible for preparing and maintaining the Records upon reasonable prior notice during normal business hours at
the place or places where the Records are normally kept. Tenant and its representatives shall execute a reasonable confidentiality agreement in favor of Landlord prior to any such examination. Any representative retained by Tenant shall 

  

 21 

 
be a mid-sized or larger recognized public accounting firm familiar with the accounting practices of comparable buildings in downtown Chicago. Tenant may
take exception to matters included in Taxes, Operating Expenses or Shared Facilities Costs or matters excluded from Shared Facilities Income or Landlord’s billings to Tenant for Taxes, Operating Expenses or Net Share Facilities Costs or
Landlord’s payments to Tenant for Net Shared Facilities Income, by sending notice specifying such exception and the reasons therefor to Landlord no later than one hundred twenty (120) days after Landlord, following receipt of a Records
Examination Request, makes the Records available for examination (and notifies Tenant that the same are so available). The Statement for any calendar year shall be binding upon Landlord. The Statement for any calendar year shall be binding upon
Tenant except for any matters as to which Tenant, after timely delivering a Records Examination Request, timely objects, as set forth above; provided, however that if, for any calendar year (the “calendar year in question”), Tenant
was overbilled for either Taxes, Operating Expenses or Net Shared Facilities Costs, as the case may be, by more than five percent (5%) (considering Taxes, Operating Expenses and Net Shared Facilities Costs separately), then Tenant shall be
given a new opportunity, with respect to the two calendar years preceding the calendar year in question, to review the Records for and take exception to the items of Taxes, Operating Expenses or Net Shared Facilities Costs (as the case may be) for
which Tenant was overbilled (and, for the purpose of applying the foregoing provisions of this Paragraph 3(F) to such new opportunity, the Statements for such two preceding years shall be deemed to have been issued to Tenant upon the date it is
determined that Tenant was so overbilled for the calendar year in question). In any event, Tenant acknowledges that Landlord’s ability to budget depends on the finality of such Statement, and accordingly agrees that time is of the essence of
this Paragraph. If Tenant timely takes any exception as provided herein, and Landlord and Tenant fail to reach a mutually satisfactory resolution thereof within thirty (30) days after Tenant has taken such exception, such matter shall be
resolved by an independent third party arbitrator selected by Landlord and Tenant who is a certified public accountant from a large public accounting firm familiar with the accounting practices of comparable office buildings in downtown Chicago. If
Landlord and Tenant fail to agree upon such arbitrator within thirty (30) days after their failure to resolve Tenant’s exception to the Statement, either party may request the President of the Illinois CPA Society to appoint such
arbitrator who shall be appointed within thirty (30) days after such request. The costs of such arbitrator shall be assessed equally to Landlord and Tenant. The determination of such arbitrator shall be made within thirty (30) days after
such arbitrator is selected, and shall be final, binding, and conclusive upon the parties. Tenant shall pay all of the costs of Tenant’s accountant/auditor associated with such examination and dispute, unless it is finally determined that
Tenant was overbilled with respect to Operating Expenses, Net Shared Facilities Costs or Taxes by more than five percent (5%) (considering each of the foregoing separately), in which case, Landlord shall pay the reasonable costs of
Tenant’s accountant/auditor with respect to such Operating Expenses, Net Shared Facilities Costs or Taxes, as the case may be. Pending resolution of any such exceptions in the foregoing manner, Tenant shall continue paying Taxes, Operating
Expenses and Net Shared Facilities Costs in the amounts determined by Landlord, subject to adjustment after any such exceptions are so resolved.

 (G) Rent attributable to Fitness Center, Cafeteria and Circulation Area. 
 (i) Commencing on the Fitness Center Commencement Date, Tenant shall pay Landlord, as additional rent in respect of the Premises,
Tenant’s SFR Share of the amounts set forth on Exhibit B-2 attached hereto. Tenant shall pay such amounts on the first day of each calendar month during the Term commencing on the Fitness Center Commencement Date at the same time
and in the same place and manner as payments of Net Rent which are due and payable hereunder. 
 (ii) Commencing on the
Cafeteria Commencement Date, Tenant shall pay Landlord, as additional rent in respect of the Premises, Tenant’s SFR Share of the amounts set forth on Exhibit B-3 attached hereto. Tenant shall pay such amounts on the first day of

 (iii) Commencing on the earlier to occur of (a) the Fitness
Center Commencement Date and (b) the Cafeteria Commencement Date, Tenant shall pay Landlord, as additional rent in respect of the Premises, Tenant’s SFR Share of the amounts set forth in Exhibit B-4 attached hereto. Tenant shall pay
such amounts on the first day of each calendar month during the Term at the same time and in the same place and manner as payments of Net Rent which are due and payable hereunder. 
 (H) Net Shared Facilities Income. If, for any calendar year, the Shared Facilities Income relative to any Shared Facility shall exceed the Shared
Facilities Costs relative to such Shared Facility (such excess being herein called “Net Shared Facilities Income”) then, simultaneously with Landlord’s delivering to Tenant the Statement for such calendar year, Landlord shall pay to
Tenant the Tenant’s SFC Share of such excess. 
 (I) Rent and Other Charges. Net Rent, Additional Rent for Taxes, Operating
Expenses and Net Shared Facilities Costs, Additional Rent pursuant to Paragraph 3(G) above, and any other amounts which Tenant is or becomes obligated to pay Landlord under this Lease or other agreement entered in connection herewith, are
sometimes herein referred to collectively as “Rent,” and all remedies applicable to the non-payment of Rent shall be applicable thereto. Rent shall be paid in good funds by check or wire transfer which at the time or times of
payment represents legal tender for public and private debts in the United States of America, at any office maintained by Landlord or its agent at the Property, or at such other place in the United States of America as Landlord may designate. All
rent and other amounts which Tenant is or becomes obligated to pay Landlord pursuant to this Article 3 are sometimes herein referred to collectively as “Additional Rent.” 
 Rent shall be paid without any prior demand or notice therefor and without any deduction, set-off, or counterclaim, or relief from any valuation or appraisement laws,
except to the extent otherwise expressly provided to the contrary in this Lease.

a fee established by Landlord equal to the costs of such operator or personnel. 
 (iv) Use of the Building’s six bay

employ union labor if Landlord’s janitorial cleaning contractor employs union labor) subject to the approval of such contractors in advance by Landlord as provided in Paragraph 6(A)(iv) above. 
 (vi) Such other extra utilities or services as Tenant may from time to time request, provided (a) the same are reasonable and
feasible for Landlord to provide and do not involve material modifications or additions to the Property or existing Building systems or equipment, and (b) Landlord shall receive Tenant’s request reasonably in advance (all of which extra
utilities or services provided under this Paragraph 6(B)(vi) are hereinafter referred to as “Extra Utilities and Services”). Tenant shall pay Landlord for such Extra Utilities and Services at a rate equal to Landlord’s

 All charges under this Paragraph 6(B) shall be due at the same time as the
installment of Net Rent with which the same are billed, or if billed separately, shall be due within thirty (30) days after such billing. Landlord may comply with written or oral requests for service under this Paragraph 6(B) by an
officer or specifically authorized employee of Tenant. Tenant shall be obligated to pay only for such services as it requests under this Paragraph 6(B). 
 (C) Interruptions of Service. 
 (i) The term “Building
Services” shall refer to the services and utilities referred to in Paragraphs 6(A), (B), (D), (F)(i), (G), (K) and (L). Landlord reserves the right to interrupt or curtail any Building Service at such times as may be necessary and for
as long as may be required (and Landlord does not warrant that any Building Services will be free from interruptions) by reason of accidents, breakdowns, acts of God, strikes or other labor troubles, or the making of repairs, replacements,
alterations or improvements, or the inability to obtain services, fuel, steam, water or supplies, governmental requirements, or other causes beyond Landlord’s reasonable control. None of the same nor related repairs to the architectural,
structural or mechanical systems of the Building shall be deemed an eviction or disturbance of Tenant’s use and possession of the Premises or any part thereof, or render Landlord liable to Tenant for abatement of Rent (except as hereinafter
provided), or relieve Tenant from performance of Tenant’s obligations under this Lease. Landlord in no event shall be liable for damages by reason of loss of profits, business interruption or other consequential damages on account of such
interruption in Building Services. 
 (ii) Except in cases of an emergency, Landlord shall give Tenant at least ten
(10) Business Days prior written notice of Landlord’s intention voluntarily to effect any interruption or curtailment of any Building Service (and, except in case of an emergency, Landlord agrees to use commercially reasonable efforts to
restrict the interruption or curtailment of chilled water, condenser water, electricity, domestic water, HVAC service, service under Paragraph 6(F)(i), and service under Paragraph 6(G) to Saturdays, Sundays and Holidays). Tenant shall have
the right (but only once with respect to any particular such interruption 

  

 39 

 
or curtailment), by notice given to Landlord within three (3) Business Days after Tenant’s receipt of such notice from Landlord, to require
Landlord to postpone such interruption or curtailment for up to fifteen (15) Business Days beyond the date set forth in Landlord’s notice. 
 (iii) Landlord shall use reasonable efforts to minimize the extent and duration of any interruption of curtailment of any Building Service. 
 (iv) Except for breakdowns, emergencies or work which requires taking an elevator out of service for longer than a single evening
(“Major Elevator Work”), elevator maintenance and repair work shall be performed outside of Regular Business Hours. Landlord shall use reasonable efforts to limit Major Elevator Work to one elevator per bank at a time. 

(v) Whenever service under Paragraph 6(G) is interrupted or curtailed, Landlord shall provide equivalent security for the
Building, either by closing off the entrances affected or by manual means. 
 (vi) As used in this Lease, the term
“Regular Business Hours” shall mean the hours of 8:00 am to 6:00 pm on Business Days. 
 (D) Electrical Service.

 (i) As more fully described in Exhibit H, the Landlord’s Work includes a high voltage electrical riser and
transformer vaults and transformers located on each floor, all of which shall be owned and operated by the local electrical distribution utility. Except for Landlord’s obligation to complete the Landlord’s Work, Tenant shall (a) make
its own arrangements with the local electrical distribution utility for the delivery of electricity to the Premises, and (b) from time to time make its own arrangements with the local electrical distribution utility or other supplier selected
by Tenant for the supply of electricity for the Premises, subject to Landlord’s approval of any such other supplier, such approval shall not be unreasonably withheld. Tenant shall pay, as and when due, directly to (x) the local electrical
distribution utility for the delivery of electricity to the Premises, and (y) the local electrical distribution utility or other supplier selected by Tenant as aforesaid for the supply of electricity for the Premises; provided, however, that if
for any reason Tenant is not billed directly for electrical service, Landlord shall forward each bill received by it with respect to the Premises to Tenant and Tenant shall pay it promptly in accordance with its terms. Landlord agrees (1) that
subject to Landlord review and approval, which shall not be unreasonably withheld, Tenant may install electrical distribution equipment in any electrical closet located on any floor on which a portion of the Premises is located and (2) that, in
the case of any full floor leased to Tenant hereunder, and (2) that no other tenant shall be permitted to install any equipment therein, subject to Landlord’s right to install therein conduit for the benefit of more than one floor of the
Building. 
  

 40 

 (ii) Landlord shall be responsible for providing electricity for (a) the Common
Areas and the other service or utility areas of the Building, including that necessary for Landlord to operate the elevators and provide HVAC and other services required by this Lease to be provided by it, and (b) the Shared Facilities (all of
the foregoing being herein called the “Landlord Electricity”). Landlord has advised Tenant that Landlord contemplates Commonwealth Edison (“Landlord’s Electric Service Provider”) to be the utility company
selected by Landlord to provide Landlord’s Electricity. Notwithstanding the foregoing, so long as the rates therefor are competitive with other comparable office buildings in downtown Chicago, if permitted by law, Landlord shall have the right
at any time and from time to time to either contract for Landlord’s Electricity from a different company or companies providing electricity service at rates competitive with other electric service providers (each such company shall hereinafter
be referred to as a “Landlord’s Alternate Service Provider” or continue to contract for Landlord’s Electricity from the Landlord’s Electric Service Provider, and in computing the amount of Operating Expenses and
Shared Facilities Costs. Landlord shall take into account any lower rates or rebates received from or through Landlord’s Electric Service Provider or such Landlord’s Alternate Service Provider. 
 (iii) If Tenant’s use of electricity in any portion of the Building located outside of the Premises is not separately metered for any
reason, Tenant shall pay Landlord as Additional Rent, in monthly installments at the time prescribed for monthly installments of Net Rent, an amount, as reasonably estimated by Landlord from time to time (and confirmed by Tenant’s engineers),
and based upon evaluations made by an engineer selected by Landlord and reasonably approved by Tenant, that Tenant otherwise would pay for such electricity. Said estimated amount shall be as if the same were separately metered to the Premises by the
local electric utility company and billed to Tenant at such utility company’s then-current rates for similar customers. 
 (iv) Tenant shall make no alterations or additions to the electric equipment or appliances used within or serving the Premises which would overload the CT cabinets or switches on any floor of the Premises, provided, however, that, Tenant
shall have the right, subject to Landlord’s approval, not to be unreasonably withheld, to (a) bring electricity from one floor of the Premises to another, and (b) install additional CT cabinets, switches, transformers and other
electrical distribution equipment and, if necessary, to construct within the Premises additional vaults for those purposes. Work affecting the Building’s electrical system will be done by either Landlord’s Contractors or, if Tenant shall
so elect, contractors employed by Tenant and reasonably approved by Landlord, in both cases at Tenant’s expense with respect to any work performed by or on behalf of Tenant. Landlord shall not limit Tenant to one or a limited number of
contractors for this work. Tenant covenants and agrees that at all times its use of electrical current shall never exceed the capacity of the feeders to the Building or the risers installed therein as more fully described in Exhibit H
hereto. 
 (E) Programs. Notwithstanding anything to the contrary in this Article 6 or elsewhere in this Lease, Landlord shall
have the right to institute such energy conservation policies, programs and measures on a Building-wide basis as may be required to comply with any Laws. 
  

 41 

 (F) Telephone and Data. 
 (i) As a part of Landlord’s Work Landlord shall construct, and thereafter Landlord shall operate, maintain, repair and replace, a
telecommunications infrastructure (“Landlord’s Telecommunication Infrastructure”) consisting of:

	 	(2)	not fewer than two (2) 4-inch conduits, not fewer than one (1) of which runs from the boundary line of the Land into each Building NetPOP Room, 

 

	 	(3)	two (2) vertical pathways for conduits, one from each of the Building NetPOP Rooms to the top floor of the Building (each a “Building Telecommunications Wiring
Room”) as shown on the Existing Drawings, and 

  

	 	(4)	one (1) room on an upper level of the Building as Landlord shall designate for satellite communications equipment (the “Building SatPOP Room”).

 (ii) Tenant shall be permitted to use up to Tenant’s Pro Rata Share of the cross sectional area of the
Building Telecommunications Wiring Rooms and the Building SatPOP Room for the installation of such conduits (including pullboxes) as Tenant shall require (a) from the Building NetPOP Rooms and the Building SatPOP Room to any floors or floors of
the Premises, or (b) among floors of the Premises. The installation, maintenance, repair and replacement of any such conduits in the Building Communications Wiring Rooms shall be performed by contractors selected by Tenant and approved in
advance by Landlord, such approval not to be unreasonably withheld, and, at Landlord’s election, under the supervision of Landlord’s riser manager. 
 (iii) Tenant shall be permitted to obtain telecommunications service (voice and/or data) from such providers as it elects from time to
time. If Tenant shall so request, Landlord shall permit any such providers to install facilities in the Building NetPOP Rooms, subject to availability. Landlord shall not limit the number of, or impose any charge or other requirements on, such
providers. 
 (G) Building Security. Landlord shall provide security services as provided in Exhibit S hereto. 

(H) Efficient First-Class Operation. Landlord shall use commercially reasonable efforts to operate or cause to be operated, the Property in a
first-class and efficient manner and Landlord shall provide or cause to be provided management and services of a quality consistent in all material respects with the standards from time to time applicable to the operation of comparable office
buildings in the downtown Chicago area (“First Class Standards”). Landlord’s obligations under this Paragraph 6(H) are in addition to Landlord’s obligations under all other provisions of this Lease; if in any case a
higher or specific standard is prescribed by this Lease, such higher or specific standard shall prevail; if in any case a higher or specific standard is prescribed by this Lease, such higher or specific standard shall prevail. 
  

 42 

 (I) Property Management Company. Landlord shall hire a property management firm to manage and
operate the Property that is either affiliated with Landlord or is experienced in the third-party management and operation of similar office buildings. 
 (J) Building Directory. Landlord will list the name of Tenant, and, at Tenant’s specific written request, Tenant’s specific departments in the Premises, its principals and executives who are working
in the Building (and the name(s) of any sub-tenant(s) and their respective departments, principals and executives), on the Building directory and in any computer or other directory serving the Building at no cost to Tenant (subject to inclusion in
Operating Expenses). Landlord shall make such subsequent additions, deletions and changes as Tenant requests in and to the initial listing after the Commencement Date on a monthly basis without charge (other than as included in Operating Expenses).
If the Building’s system at any time provides the capability for tenants to modify their own listings, Landlord shall permit Tenant to have such access to such system without charge to modify its listings. Landlord shall maintain such
directories and keep computer directories operational at all times during the Term and the cost thereof shall be included in Operating Expenses pursuant to Article 3 above. 
 (K) Use of Fire Stairs. So long as permitted by applicable Laws, including building and fire codes and requirements, Tenant, at its sole cost and
expense at all times during the Term of this Lease (i) may use the fire exit stairways for travel between and among contiguous floors of the Building on which the Premises are located (but in no event shall Tenant be allowed to use such
stairways for travel to or through a floor no part of which is included in the Premises except in emergency situations), and (ii) with Landlord’s prior approval (such approval not to be unreasonably withheld), may upgrade Building standard
improvements therein in accordance with the terms of Article 8 hereof (including installation of a card reader or other system exclusively for Tenant’s use, as well as installation of drywall, carpeting, paint of Tenant’s choice, and
light fixtures in accordance with all applicable codes). Tenant expressly acknowledges and agrees that Landlord shall have no obligation to provide security services in the areas of the fire exit stairways and Landlord shall not be liable for loss
or damage to person or property sustained by Tenant or any other person due to the use thereof. If Tenant uses such fire exit stairways pursuant to this Paragraph 6(K), Tenant shall cause the insurance it is required to maintain pursuant to
Paragraph 11(B) below to cover any such use by Tenant and Tenant’s employees, agents, contractors and invitees. 
 (L)
Access to Alley. Landlord shall use commercially reasonable efforts (including, without limitation, seeking the cooperation of the owner of the building located at One South Wacker, securing “no-parking” signs from the City of
Chicago, and paying any fees charged by the City of Chicago for such signs) to: (i) prevent vehicles from parking or stopping in the alley adjacent to the Building’s loading dock in a manner that would interfere with access thereto and
(ii) cause the City of Chicago to maintain the alley as a “no parking” zone and enforce such “no parking” restrictions. 
  

 43 

 (M) Other Tenants. Landlord covenants that is has not, and that it shall not, grant to any
Building tenant or other person any rights in, to or with respect to the Building Services (i) which would prevent Landlord from performing its obligations pursuant to this Article 6, or (ii) to hire or fire, or approve the hiring or
firing of, any contractor engaged in the operation or maintenance of the Building or any employee thereof, except that this clause (ii) shall not be deemed to prevent Landlord from granting (a) to any other Participant the same rights as
Tenant has under Exhibit S with respect to the Building’s director of security, or (b) to any other tenant in the Building the same rights with respect to its premises as Tenant has under Paragraph 18(B) with respect to the
Premises.

 (B) Landlord Designation of Participants, Assignments, Major Subleases, etc. 
 (i) Designation of Participant Leases. 
  

	 	(1)	 Landlord hereby represents that the Initial A Lease is a Qualified Participant Lease and hereby designates the Initial A Lease as the initial A Participant Lease.
If (a) the A Participant Lease is terminated or under the provisions of the A Participant Lease corresponding to Paragraph 7(A)(v)(2) hereof the tenant under the A Participant Lease shall cease to be a Participant, and (b) Landlord desires
to substitute as the A Participant Lease a lease to any other person then, whether or not the same is in effect, Landlord shall notify Tenant and any other then Participant. Such notice shall identify and briefly describe such person. Tenant or such

Paragraph 7(B)(iv), Tenant agrees not to unreasonably reject any person. If such person is not timely rejected (rejection by one constituting rejection, even if no other rejects) then, subject to the next sentence, Landlord shall have the right, by
notice to Tenant and any other then Participant given within 270 days of the lapse of such ten (10) Business Day period, to designate as the substitute A Participant Lease any lease to such person which is a Qualified Participant Lease, which

at least 100,000 square feet of Rentable Area, and is then in effect). Any lease designated in or as provided in this Paragraph 7(B)(i)(1) as the A Participant Lease shall, as amended and extended from time to time, remain the A Participant
Lease so long as it remains in effect, and, so long as such lease, as amended and extended from time to

time, remains in effect, Landlord shall not have the right to revoke such designation or designate a substitute A Participant Lease. After a lease has been
designated in or as provided in this Paragraph 7(B)(i)(1) as the A Participant Lease, Landlord shall not thereafter amend the same in such a way that it ceases to be a Qualified Participant Lease. 

  

	 	(2)	Landlord hereby represents that the Initial B Lease is a Qualified Participant Lease and hereby designates the Initial B Lease as the initial B Participant Lease. If (a) the B
Participant Lease is terminated or under the provisions of the B Participant Lease corresponding to Paragraph 7(A)(v)(3) hereof the tenant under the A Participant Lease shall cease to be a Participant, and (b) Landlord desires to substitute as
the B Participant Lease a lease to any other person then, whether or not the same is in effect, Landlord shall notify Tenant and any other then Participant. Such notice shall identify and briefly describe such person. Tenant or such other then

7(B)(iv), Tenant agrees not to unreasonably reject any person. If such person is not timely rejected (rejection by one constituting rejection, even if no other rejects) then, subject to the next sentence, Landlord shall have the right, by notice to
Tenant and any other then Participant given within 270 days of the lapse of such ten (10) Business Day period, to designate as the substitute B Participant Lease any lease to such person which is a Qualified Participant Lease, which demises at
least 100,000 square feet of Rentable Area, and which is in effect at the time of such designation (and any such notice of designation shall constitute a representation by Landlord that such lease is a Qualified Participant Lease, demises at least
100,000 square feet of Rentable Area, and is then in effect). Any lease designated in or as provided in this Paragraph 7(B)(i)(2) as the B Participant Lease shall, as amended and extended from time to time, remain the B Participant Lease so
long as it remains in effect, and, so long as such lease, as amended and extended from time to time, remains in effect, Landlord shall not have the right to revoke such designation or designate a substitute B Participant Lease. After a lease has
been designated in or as provided in this Paragraph 7(B)(i)(1) as the B Participant Lease, Landlord shall not thereafter amend the same in such a way that it ceases to be a Qualified Participant Lease.

(5) Business Days of its receipt of such notice, forward the same to all other then Participants. If, within ten (10) Business Days of its receipt of such notice, any such other Participant shall reject such person (rejection by one

such sublease. Such notice shall identify and briefly describe such person (or persons). Landlord shall, within five (5) Business Days of the receipt of such notice, forward the same to all other then Participants. If, within ten
(10) Business Days of its receipt of such notice, any such other Participant shall reject such person (or persons) (rejecting by one constituting rejection, even if no other rejects) then (a) Landlord shall promptly notify Tenant of such
rejection, and (b) the provisions of Paragraph 7(a)(v)(1)(b) shall be applicable.

(subject to Paragraph 7(A)(vii)). 
 (iii) Except to the extent that its doing so would be inconsistent with the foregoing
provisions of this Paragraph 7(D), Landlord shall operate, maintain, repair and replace the Fitness Center in accordance with such directions, including but not limited to any directions pertaining to the selection of the operator of the

 59 

	 	(4)	The Cafeteria shall serve breakfast and lunch; provided, however, that by Unanimous Instrument one or more of such meals may be eliminated or dinner may be added.

subject to approval by Majority Instrument, to all but not less than all other tenants or occupants of premises in the Building. The rates charged for such service shall be established from time to time by Majority Instrument, it being the goal of

	 	(12)	Except as may be provided by Unanimous Instrument, Landlord shall permit the Participants and their Permittees and, subject to approval by Unanimous Instrument, any other tenant or
occupant of premises in the Building, to reserve all or portions of the Cafeteria on an occasional basis for special events outside of the Cafeteria’s hours of operation from time to time established as herein provided. Landlord shall accept

with respect to the Cafeteria which would prevent Landlord from performing its obligations pursuant to this Paragraph 7(E) and (y) each Participant has, and shall throughout the Term shall have, the same rights and obligations (and
only the same rights and obligations) relative to the Cafeteria (including obligations for payment) under its lease or otherwise as Tenant has under this Lease or otherwise (subject to Paragraph 7(A)(vii)).

shall operate, maintain, repair and replace the Cafeteria in accordance with such directions, including but not limited to any directions pertaining to the contract between Landlord and any operator of the Cafeteria, and its termination and any
directions pertaining to rules and regulations, as, in either case, may be given from time to time by Majority Instrument. 
 Notwithstanding anything to the
contrary contained in this Lease, Landlord’s obligation to operate, maintain, repair and replace the Cafeteria is excused to the extent and for as long as Tenant is not paying (a) Tenant’s SFC Share of Net Shared Facilities Costs in
respect of the Cafeteria and (b) the additional rent required pursuant to Paragraph 3(G)(ii) above.

	 	(4)	Alteration Work whose cost is not reasonably expected to exceed $100,000 (provided such Alteration Work is not of a type for which Landlord may withhold its consent pursuant to
Paragraph 8(A)(i) above). 

  

 62 

 The term Alteration Work shall not include the initial improvements to the Original Premises which are
described in the Workletter. 
 (B) Landlord Requirements. As a condition to Tenant’s performing any Alteration Work, Landlord
may impose reasonable requirements (generally applicable throughout the Building to all tenants), including, to the extent reasonable in the circumstances, the following: 
 (i) the submission of plans and specifications for Landlord’s prior written approval which shall not unreasonably be withheld, except
(a) that no such plans and specifications shall be required for Alteration Work pursuant to clause (1) or (2) of Paragraph 8(A)(ii), and (b) such approval shall not be required for Alteration Work pursuant to clause
(4) of Paragraph 8(A)(ii), 
 (ii) obtaining necessary permits, 
 (iii) obtaining insurance (including from contractors and subcontractors) as provided in the Workletter and providing insurance
certificates which name Landlord and such other parties as are identified by Landlord as additional insureds thereunder, 
 (iv) Landlord’s prior approval of contractors and subcontractors (which approval shall not be unreasonably withheld), 
 (v) prior receipt of copies of all contracts and subcontracts, 
 (vi) receipt of sworn statements and lien waivers
as work is completed, 
 (vii) use of union labor (if Landlord uses union labor), 
 (viii) receipt of affidavits from engineers approved by Landlord, which approval shall not be unreasonably withheld, stating that the
Alteration Work will not adversely affect the Building’s structure, or the electrical system of the Building inward of the disconnect switches serving the Premises, or any other system of the Building inward of the point of connection between
the Base Building Work and improvements made by Tenant, 
 (ix) bonds, 
 (x) construction escrow payouts, 
 (xi) reasonable requirements as to the manner and times in which such Alteration Work shall be conducted, and 
 (xii) submission of “as built” drawings for all such Alteration Work. 
  

 63 

 Notwithstanding the foregoing, (a) so long as this Lease has not been assigned (other than under
Paragraph 21(C)), Landlord shall not require (1) receipt of copies of contracts or subcontracts, (2) receipt of sworn statements or lien waivers, (3) posting of any bonds, or (4) the establishment of any construction escrow
(but Tenant shall furnish such indemnities against mechanic’s or materialmen’s liens as Landlord’s Mortgagee may require), or (b) Landlord shall not require the payment of any supervisory, administrative or other fee not provided
for in this Lease, and (c) Landlord shall not impose any removal or restoration requirement other than as set forth in Paragraph 8(C). 
 Whenever in this Lease, Landlord has a right of approval over any architect, engineer, contractor, or subcontractor for any trade to be used by Tenant, Landlord shall not limit Tenant to one or a limited number of architects, engineers,
contractors, or subcontractors for such trade. 
 All welding and all Alteration Work which is audible in office premises other than the
Premises shall be done outside of Regular Business Hours. All alterations and additions shall comply with all insurance requirements applicable to the Building and with all ordinances, statutes, and regulations of all governmental bodies,
departments, or agencies having jurisdiction over the Building. All Alteration Work shall be performed in a good and workmanlike manner and all materials used shall be of a high quality comparable to or better than those materials used in the
Premises and Property. Alteration Work which requires Landlord’s consent shall be completed in accordance with plans and specifications approved by Landlord. Landlord shall have the right to observe the performance of any Alteration Work
requiring its consent, provided that Tenant shall not be required to defer Alteration Work if Landlord does not have an observer available. 
 Tenant shall pay only for any of Landlord’s actual and reasonable out-of-pocket costs and expenses paid to third parties (i) in connection with any review of plans and specifications for, or inspection of, Alteration Work which
requires expertise beyond Landlord’s and its managing agent’s internal capabilities and (ii) for Landlord’s observation of such Alteration Work outside of the Premises or any affecting basic Building systems. 
 If Landlord consents or observes, the same shall not be deemed a warranty as to the adequacy of the design, workmanship or quality of materials, and
Landlord hereby expressly disclaims any responsibility or liability for the same. 
 If Landlord fails, within ten (10) Business Days of
its receipt of Tenant’s request for consent to or approval of any Alteration Work, plans, specifications, contractors or subcontractors, or any other submission made pursuant to this Article 8 that requires Landlord’s consent or
approval, to notify Tenant that Landlord withholds such consent or approval (including therewith a statement of its reasons therefor with reasonable specificity), Landlord shall be deemed to have approved and consented to the same. 
 Landlord shall under no circumstances have any obligation to repair, maintain or replace any portion of the Alteration Work. 
 Landlord shall reasonably cooperate, at Tenant’s expense, with Tenant’s efforts to obtain any necessary permits or licenses and shall execute
any applications or other documents required by Law or any governmental agency to be executed by the building owner; provided, however, Tenant shall indemnify and hold harmless Landlord for any cost, expense or liability incurred or associated with
such applications or other documents. 
  

 64 

 (C) Special Alterations. 
 (i) As used herein the term “Special Alteration” shall mean any of the following performed pursuant to this
Article 8 (i.e., not pursuant to the Workletter): (i) structural work (other than beam cuts, any floor opening less than 25 square inches in size, or any internal staircases, stairwells or elevators between floors on which portions of the
Premises are located, which shall not constitute a Special Alteration), (ii) safes, (iii) decorative water features, (iv) special flooring (other than raised flooring which shall not constitute a Special Alteration), or (v) other
unusual installations requiring extraordinary demolition costs for the removal thereof (including UPS systems, generators, fuel tanks which shall constitute Special Alterations but excluding fuel, electrical or telecommunications risers and conduits
which shall not constitute Special Alterations). 
 (ii) If Landlord expressly states in writing in its consent to any Special
Alteration that Landlord may require such Special Alteration to be removed upon expiration of the Term or earlier termination of this Lease or Tenant’s right to possession, Landlord shall be deemed to have reserved its rights to require such
removal by Tenant in accordance with the terms of Article 13 hereof, but otherwise Landlord may not require such removal. 
 (D)
Liens. Tenant shall keep the Property and Premises free from any mechanic’s, materialman’s or similar liens or other such encumbrances in connection with any Alteration Work on or respecting the Premises not performed by or at the
request of Landlord, and shall indemnify and hold Landlord harmless from and against any claims, liabilities, judgments, or costs (including attorneys’ fees) arising out of such liens or encumbrances or in connection therewith. Within thirty
(30) days after written notice from Landlord, Tenant shall remove any such lien or encumbrance by bond or otherwise, or provide a title insurance endorsement reasonably satisfactory to Landlord and its Mortgagees or Ground Lessors, and covering
all costs of defense, in which case Tenant shall not be deemed to be in breach and shall have the right to contest in good faith or otherwise deal with such lien claims as Tenant deems best. If Tenant shall fail to do so, Landlord may, after
delivery of notice to Tenant of Landlord’s intent so to act (and Tenant’s further failure to remove, bond over, or insure over such lien or encumbrance as aforesaid within five (5) days after receipt of such notice), bond over, insure
over, or pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof. In each case, the amount so paid shall be deemed additional Rent under this Lease payable upon demand, without
limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord’s title to the Property or Premises to any liens or encumbrances whether
claimed by operation of law or express or implied contract. Any claim to a lien or encumbrance upon the Property or Premises arising in connection with any Alteration Work on or respecting the Premises not performed by or at the request of Landlord
shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to Landlord’s title to the Property and Premises. 
  

 65 

 ARTICLE 9. 
 Maintenance and Repairs 
 (A) Tenant’s Repairs and Maintenance. Except for
Landlord’s obligations under this Lease, Tenant shall maintain and keep in good and sanitary condition, working order and repair the Premises including any Tenant Work and Alteration Work installed therein by Tenant but not including the Base
Building Work or any property installed therein by Landlord (“Tenant’s Repairs”) subject to ordinary wear and tear, casualty and condemnation (to which this Article 9 shall not apply). In the event that any Tenant’s
Repairs are required, Tenant shall promptly arrange for the same either through Landlord (in which case Tenant shall reimburse Landlord for its actual out-of-pocket costs of performing the same) or, if Tenant so elects, using such other contractors
as Tenant shall select, subject to Landlord’s approval not to be unreasonably withheld. 
 (B) Landlord’s Repairs and
Maintenance. Landlord shall perform all maintenance and make all repairs and replacements (collectively referred to herein as “Landlord Repairs”) necessary to keep all the Base Building Work, in good and sanitary condition, in
compliance with all Laws, and in working order and repair, consistent with comparable office buildings in downtown Chicago, Illinois at all times during the Term, subject to casualty and condemnation (to which this Article 9 shall not apply).
No other promises of Landlord to alter, remodel, improve, repair, decorate or clean the Property or any part thereof have been made and no representation respecting the condition of the Property or any part thereof has been made to Tenant by or on
behalf of the Landlord except to the extent expressly set forth in this Lease. Subject to Paragraph 6(C), Landlord shall cause Landlord’s Repairs to be performed with reasonable commercial diligence, and may, at its option, perform such
Landlord Repairs during Regular Business Hours; provided, that (1) except in the case of emergency, if and to the extent that Tenant shall request, Landlord shall use commercially reasonable efforts (which shall include the payment of overtime
wages) to perform outside of Regular Business Hours any Landlord Repairs in or the performance of which adversely affects the use of occupancy of the Premises, and (2) in the case of emergency or any condition the remediation of which is
reasonably necessary for Tenant’s use or occupancy of the Premises or any portion thereof, Landlord shall cause Landlord’s Repairs to be performed continuously during and after Regular Business Hours (subject to Unavoidable Delays).

 (C) Tenant Self-Help. If 
 (i) Landlord fails to commence any Landlord Repairs of a condition which materially and adversely affects Tenant’s ability to conduct business in the Premises, and such failure continues for five
(5) Business Days following Landlord’s receipt of written notice of such failure, or 
 (ii) Landlord fails
diligently to prosecute any Landlord Repairs of a condition which materially and adversely affects Tenant’s ability to conduct business in the Premises and such failure continues for five (5) Business Days following Landlord’s receipt
of written notice of such failure then Tenant, upon twenty-four (24) hours prior written notice (“Tenant’s Self-Help 

  

 66 

 
Notice”) delivered to Landlord (with an additional copy to the Building Office), shall have the right to perform such portion of the Landlord
Repairs as may be necessary to remedy the material adverse effect on the conduct of Tenant’s business in the Premises that such condition shall have caused (“Tenant Self-Help”). Tenant’s Self-Help Notice shall identify
with specificity the nature of the Landlord Repairs to be undertaken by Tenant, the contractor to be engaged by Tenant to make such repairs, and shall include a copy of any cost or bid proposal submitted to Tenant by such contractor (which
contractor shall be duly licensed in the City of Chicago and insured in accordance with the provisions of Article 8). If Landlord, at any time prior to the commencement of such Tenant Self-Help by Tenant or Tenant’s contractors, commences
and diligently prosecutes the performance of such Landlord Repairs, Tenant shall have no right to perform such Landlord Repairs hereunder so long as Landlord is diligently prosecuting the same. Landlord shall reimburse the actual out-of-pocket
reasonable costs of Tenant’s Self Help within thirty (30) days following Tenant’s delivery of: (a) a written notice describing in reasonable detail the actions taken by Tenant, and (b) reasonably satisfactory evidence of the
cost of such remedy. 
 If Tenant undertakes any action pursuant to the preceding paragraph, 
 (iii) Tenant shall (1) proceed in accordance with all applicable Laws; (2) retain to effect such actions only such reputable
contractors and suppliers as are duly licensed in the City of Chicago and insured in accordance with the provisions of Article 8; (3) effect such repairs in a good and workmanlike and commercially reasonable manner; (4) use new or
like new materials; and (5) take reasonable efforts to minimize any material interference or impact on the other tenants and occupants of the Property, and 
 (iv) Tenant shall reimburse Landlord for, and shall indemnify and hold harmless the Landlord Protected Parties against any claims arising
from, any damage to person or property resulting from the exercise by Tenant of Tenant Self-Help. Tenant’s obligation to reimburse Landlord for costs incurred by Landlord for damage to property shall be limited to the amount by which such
damages exceed the amount of any insurance proceeds which Landlord collected (or would have collected if Landlord (a) had maintained the insurance required by this Lease; (b) had timely filed a claim thereunder; or (c) had not been
prevented from recovering on such claim by reason of the insurer being insolvent or otherwise financially unable to perform its obligations under the policy.). 
  

 67 

 ARTICLE 10. 
 Casualty Damage 
 (A) Casualty. 
 (i) If the Base Building Work shall be damaged by fire or other casualty, Landlord shall repair and restore the same
(“Landlord’s Restoration Work”) with reasonable promptness to substantially the condition existing prior to the casualty, except for modifications required by zoning and building codes and other Laws then in effect, and except
as otherwise provided in Paragraph 10(B) below. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof.

 (ii) If, as a result of any such damage, all or any portion of the Premises is rendered Untenantable, then Landlord, within
sixty (60) days after the occurrence of such damage, shall cause to be delivered to Tenant an estimate, prepared by a qualified, independent, experienced and reputable architect, of the number of days (assuming no delays in the receipt of
insurance proceeds, no overtime or other premiums, and no Unavoidable Delays), measured from the date of the casualty, that will be required for Landlord to substantially complete the repair and restoration of (i) the Base Building Work in or
surrounding the Premises or on any floor on which any part of the Premises is located (ii) the Building systems and equipment which serve the Premises, (iii) the ground floor lobby and Pedestrian Entrances, and (iv) to the extent
required to render the Premises tenantable, any other portion of the Base Building Work (“Landlord’s Basic Restoration Work”). 
  

	 	(a)	If the aforesaid estimate exceeds 420 days, then Tenant may elect to terminate this Lease by notifying Landlord in writing of such termination no later than the 30th day following
Tenant’s receipt of such estimate from Landlord. 

  

	 	(b)	If the aforesaid estimate exceeds 90 days and such fire or casualty shall have occurred after the 365th day before the then Expiration Date, then either Landlord or Tenant may elect
to terminate this Lease by notifying the other in writing of such termination no later than, (a) the 30th day following Tenant’s receipt of such estimate from Landlord if Tenant shall so terminate the Lease, and (b) the earlier of
(i) the 30th day following Landlord’s delivery of said estimate to Tenant, or the 90th day after such fire or other casualty, if Landlord shall terminate this Lease. 

  

	 	(c)	If Landlord shall fail to cause the required architect’s estimate to be delivered timely and such failure continues for ten (10) Business Days after Tenant’s notice
to Landlord of such failure, then, for all purposes of this Article 10, an architect’s estimate of longer than 420 days shall be deemed to have been delivered to Tenant upon the eleventh (11th) Business Day after Tenant’s notice
as aforesaid, but Landlord shall not have the right to terminate this Lease on the basis of any estimate so deemed to have been delivered. 

  

 68 

 (iii) If as a result of any fire or other casualty the Base Building Work is damaged such
that a material portion of the tenant premises in the Building shall be rendered Untenantable, irrespective of whether, as a result of any such damage, all or any portion of the Premises is rendered Untenantable, then Landlord, within 60 days after
the occurrence of any such damage, shall cause to be delivered to Tenant an estimate, prepared by a qualified, independent, experienced and reputable architect, of the number of days (assuming no delays and in receipt of insurance proceeds, no
overtime or other premiums, and no Unavoidable Delays), measured from the date of the casualty, that will be required for Landlord to substantially complete and repair the restoration of the Base Building Work. If the aforesaid estimate exceeds 420
days, then, provided that as a result of such fire or other casualty leases covering not less than 50% of the Net Rentable Area of the Building then subject to lease (excluding the Premises) shall also be terminated, Landlord may elect to terminate
this Lease by notifying Tenant in writing of such termination no later than the earlier of (a) the 45th day following Landlord’s delivery of said estimate to Tenant, and (b) the 105th day after such fire or other casualty; 

(iv) Any termination notice delivered pursuant to this Paragraph 10(A) shall be effective on the date of its delivery, provided,
however, that if any portion of the Premises remains tenantable then Tenant shall have the right, in such termination notice (if given by Tenant) or by notice given within thirty (30) days of its receipt of such termination notice (if given by
Landlord), to set a different termination date with respect to the tenantable portion of the Premises no later than the 180th day following such notice. 
 (v) Landlord and Tenant each agree that the rights and remedies provided in this Article 10 shall be their sole rights and remedies on account of any damage caused by fire or other casualty, and, except as
expressly provided in this Article 10, (a) each party waives any right to terminate this Lease on account thereof, (b) Tenant waives any right to an abatement of rent on account thereof, and (c) each party waives any right to
recover damages from the other party on account of any such damage to the Premises or Property. 
 (B) Unless this Lease is terminated as
provided in Paragraph 10(A), Landlord shall proceed with reasonable diligence and promptness, given the nature of the damage to be repaired, to effect Landlord’s Restoration Work, all subject to reasonable delays for insurance adjustments,
zoning laws, building codes, and other Laws then in effect and Unavoidable Delays. Notwithstanding anything to the contrary herein set forth, neither Landlord nor (except as otherwise provided in this Paragraph 10(B)) Tenant shall have any duty
pursuant to this Article 10 or otherwise to repair or restore any of the initial leasehold improvements effected by Tenant pursuant to the Workletter or any subsequent leasehold improvements effected pursuant to Article 8 or to
Tenant’s equipment, furniture, furnishings, or personal property (as any of the same may have been altered prior to the occurrence of such casualty). If and to the extent that any damaged leasehold improvements must be removed in order for
Landlord to prosecute Landlord’s Restoration Work or to eliminate any hazard or nuisance resulting from such damaged leasehold improvements, then, after Landlord gives Tenant access for that purpose, Tenant shall proceed with reasonable
diligence, given the nature of the work, to remove such damaged leasehold improvements in accordance with applicable Laws, subject to reasonable delays for insurance adjustments and Unavoidable 

  

 69 

 
Delays. If Tenant elects to restore leasehold improvements in any portion of the Premises, Tenant shall proceed with reasonable diligence, given the nature
of the work, to effect such restoration in a good and workmanlike manner and in accordance with applicable Laws, subject to Unavoidable Delays; provided, however, that subject to the provisions of Article 8, Tenant shall be permitted to restore
the Premises to a condition different from that existing prior to the fire or other casualty. If Tenant elects not to restore the leasehold improvements in any portion of the Premises, Tenant, no later than the expiration or sooner termination of
this Lease, shall remove the damaged leasehold improvements from such portion of the Premises in accordance with applicable Laws. All of such work shall be done by Tenant at Tenant’s sole cost and expense subject to all the provisions of
Article 8 hereof. Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage carried by Landlord and Landlord acknowledges that Tenant shall be entitled to the full proceeds of all insurance coverage
carried by Tenant. 
 (C) Notwithstanding any provision in this Lease to the contrary, Landlord shall not be liable for any loss of business,
inconvenience or annoyance arising from any repair, restoration or rehabilitation of any portion of the Premises or the Building as a result of any damage from fire or other casualty. 
 (D) If any fire or casualty damage to the leasehold improvements in the Premises or to the Base Building Work renders all or any portion of the Premises
Untenantable, then Net Rent and Rent under Article 3 shall abate with respect to the Untenantable space (it being understood that for purposes of this abatement all Fitness Center Rent and Cafeteria Rent shall be allocated across the entire
Rentable Area of the Premises (excluding the Basement Premises)) during the period beginning with the date such space becomes Untenantable and Tenant is unable or ceases to use such space for the normal conduct of its business and ending when

 (i) Landlord shall have completed Landlord’s Basic Restoration Work, and 
 (ii) there shall have elapsed a period of time (not to exceed 270 days) sufficient for Tenant, commencing after 
  

	 	(1)	Landlord shall have provided Tenant with access to the Premises for that purpose and completed Landlord’s Basic Restoration Work, and 

  

	 	(2)	Landlord shall have waived any right it may have to terminate the Lease pursuant to Paragraph 10(F) with respect to such fire or other casualty, 

 and proceeding with reasonable commercial diligence, to (a) complete the Tenant Work pursuant to the terms of the Workletter, if such
casualty shall have occurred prior to the Rent Commencement Date, or (b) restore the leasehold improvements to the condition existing prior to the casualty, if such casualty shall have occurred on or subsequent to the Rent Commencement Date;

  

 70 

 provided, however, that if Tenant shall sooner occupy or reoccupy such space or any portion thereof for the conduct of
its business, then such abatement shall thereupon end with respect to such space or portion thereof. Such abatement shall be in an amount bearing the same ratio to the total amount of such Net Rent and Rent under Article 3 for such period as
the portion of the Rentable Area of the Premises rendered Untenantable bears to the Rentable Area of the entire Premises. If this Lease terminates pursuant to this Article 10, Net Rent and Rent under Article 3 shall be apportioned on a per
diem basis and be paid to the date of the fire or casualty with appropriate adjustment for the portion of the Premises that Tenant continues to occupy to conduct its business from the date of the fire or casualty until said termination. 

(E) If Landlord does not complete Landlord’s Basic Restoration Work by the date which is the Outside Restoration Days Number of days after the
date of the fire or other casualty (the “Outside Restoration Date”) then Tenant, provided the Premises or portion thereof affected by such fire or other casualty remain Untenantable, shall have the right to terminate the Lease by
delivery of written notice of such election to Landlord within 10 days following the Outside Restoration Date. If Tenant timely elects to terminate this Lease pursuant to this Paragraph 10(E), Tenant’s notice of termination shall set forth
the date upon which this Lease shall terminate, which date shall be any date within the 120 day period following the date on which it shall have delivered such termination notice. The term “Outside Restoration Days Number” shall
mean (i) if the architect’s estimate under Paragraph 10(A)(ii) did not give rise to a right of termination under Paragraph 10(A)(ii), the greater of (a) 150% of the number of days set forth in such estimate, and (b) 450 days, or
(ii) otherwise, 125% of the number of days set forth in such estimate. 
 (F) The provisions of (1) Paragraph 10(A), (2) the
first sentence of Paragraph 10(B), (3) Paragraph 10(D) and Paragraph 10(E) shall not be applicable to any fire or other casualty occurring prior to the Substantial Completion Date; provided, however, that unless this Lease is terminated
pursuant to Paragraph 4(I) or Paragraph 4(J), Landlord shall repair, restore and complete Landlord’s Work in accordance with the Workletter and, in case of any Pre-SCD Casualty, the term “Landlord’s Restoration Work” as
used in Paragraph 4(I) and Paragraph 10(B) shall be deemed to refer to such repair and restoration. 
  

 71 

 ARTICLE 11. 
 Insurance, Subrogation, and Waiver of Claims 
 (A) Tenant’s Property Insurance.
Tenant, at its sole cost and expense, shall maintain in force and effect, commercial property insurance under policies issued by insurers that are licensed or authorized to conduct business in Illinois with a minimum Best rating of “A-X”
or “Excellent”. Such commercial property insurance shall, at a minimum, cover the perils insured under the ISO special causes of loss form (CP 10 03), which provides “all risk” coverage with a deductible amount (except that
Tenant shall not be required to insure against terrorism), and said insurance shall cover (i) improvements and betterments installed by or on behalf of Tenant, whether or not at Tenant’s expense, including, but not limited to, the Tenant
Work and any Alterations Work, special wall and floor coverings, special lighting fixtures, built-in cabinets and bookshelves and (ii) Tenant’s merchandise, inventory, contents, furniture, equipment or other personal property located in
the Premises. Such insurance shall provide that it is specific, primary and noncontributory, and shall contain a replacement cost endorsement and a clause pursuant to which the carriers waive all rights of subrogation against the Landlord Protected
Parties with respect to losses payable under such policies. 
 Tenant may maintain extra expense and business interruption coverage as part
of its commercial property insurance. In no event shall Landlord be liable to Tenant for any extra expense or business interruption or other consequential loss sustained by Tenant on account of any occurrence of an event insurable under the
commercial property insurance required to be carried by Tenant, whether or not such insurance is in effect, even if such loss is caused by the act or omission of Landlord, its employees, officers, directors, or agents. 
 (B) Tenant’s Liability Insurance. Tenant shall, at Tenant’s expense, maintain commercial general liability insurance covering liability
arising from premises, operations, independent contractors, personal injury, advertising injury, products, completed operations and liability assumed under an insured contract on an occurrence basis (and, to the extent applicable, host liquor or
dram shop liability insurance) under policies issued by insurers that are licensed or authorized to conduct business in Illinois with a minimum Best rating of “A-X” or “Excellent”. Limits of insurance on said policies shall be
not less than $25,000,000 combined single limit for personal injury, bodily injury, sickness and property damage for any one occurrence. Tenant’s liability policies shall name Landlord, its members, its managing agent, any Mortgagee, any Ground
Lessor and such other Affiliates of Landlord as Landlord may reasonably identify from time to time (the “Landlord Protected Parties”), as additional insureds. 
 Tenant shall also maintain workers’ compensation insurance to the extent required by statute, including Employer’s Liability limits of not less
than $500,000 per accident. 
 (C) Changes in Tenant’s Insurance. Tenant shall not be required to comply with the
provisions of Paragraph 11(A) or 11(B) provided that (i) Tenant notifies Landlord of the insurance maintained by Tenant and of any respects in which such insurance does not conform to the requirements of Paragraph 11(A) or 11(B),
(ii) Tenant maintains such insurance as is generally maintained by comparable office tenants in downtown Chicago, and (iii) Tenant shall nonetheless be required to comply with the waiver of subrogation provisions of Paragraph 11(A) and the
additional insureds provisions of Paragraph 11(B). 
  

 72 

 (D) Landlord’s Property Insurance. Landlord agrees to purchase and keep in force and effect
commercial property insurance insuring 
 (i) the Base Building Work in an amount equal to one hundred percent (100%) of
the full replacement cost of the Base Building Work (excluding footings and foundations), subject to a reasonable deductible not to exceed one percent (1%) of such full replacement cost of the Base Building Work, and 
 (ii) rent loss insurance for a period and amount of not less than one (1) year of rent. 
 Said commercial property insurance policy shall, at a minimum, cover the perils insured under the ISO special causes of loss form (CP 10 03) which provides “all
risk” coverage. Such insurance shall provide that it is specific, primary, and noncontributory, and shall contain a replacement cost endorsement and a clause pursuant to which the carrier waives all rights of subrogation against the Tenant
Protected Parties and other occupants of the Premises with respect to losses payable under such policies. All such policies shall be issued by insurers that are licensed or authorized to conduct business in Illinois with a minimum Best rating of
“A-X” or “Excellent.” 
 In no event shall Tenant be liable to Landlord for any extra expense or business interruption
(including loss of rent) or other consequential loss sustained by Landlord on account of any occurrence of an event insurable under the commercial property insurance required to be carried by Landlord, whether or not such insurance is in effect,
even if such loss is caused by the act or omission of Tenant, its employees, officers, directors, or agents. 
 It is expressly understood
that Landlord’s property insurance shall not insure improvements to the Premises that are in excess of the Base Building Work, and the cost of any insurance which in fact does cover any such other improvements shall not be included as an
Operating Expense. 
 (E) Landlord’s Liability Insurance. Landlord shall maintain commercial general liability insurance covering
liability arising from premises, operations, independent contractors, personal injury, advertising injury, products, completed operations and liability assumed under an insured contract (including tort liability of another assumed in a business
contract) on an occurrence basis. Limits on insurance on said policies shall be not less than $25,000,000 combined single limit for personal injury, bodily injury, sickness, and property damage from any one occurrence. Landlord’s liability
insurance shall name Tenant, any subtenant and such Affiliates of Tenant as Tenant may reasonably identify from time to time (the “Tenant Protected Parties”), as additional insureds. All such policies shall be issued by insurers
that are licensed or authorized to conduct business in Illinois with a minimum Best rating of “A-X” or “Excellent.” 
 Landlord shall also maintain workers’ compensation insurance as required by statute including Employer’s Liability limits of not less than $500,000.00 per occurrence. 
 (F) Changes in Landlord’s Insurance. Landlord shall not be required to comply with the provisions of Paragraph 11(D) or 11(E) provided that
(i) Landlord notifies Tenant of the insurance maintained by Landlord and of any respects in which such insurance does not conform to the requirements of Paragraph 11(D) or 11(E), (ii) Landlord maintains such insurance as is generally
maintained by owners of comparable office buildings in downtown Chicago, and (iii) Landlord shall nonetheless be required to comply with the waiver of subrogation provisions of Paragraph 11(D) and the additional insureds provisions of Paragraph
11(E). 
  

 73 

 (G) General Provisions and Evidence of Insurance. 
 Tenant shall provide Landlord with certificates evidencing such coverage as Tenant is required to maintain (and showing the Landlord Protected Parties as
additional insureds in the liability insurance policy only) prior to occupying or commencing Tenant Work in the Premises, which shall state that such insurance coverage may not be canceled without at least 30 days’ prior written notice to
Landlord, and shall provide renewal certificates to Landlord prior to expiration of such policies not less than seven (7) days prior to the expiration of said policies. 
 Within ten (10) Business Days of Tenant’s request from time to time, Landlord shall provide Tenant with certificates evidencing such coverage
as Landlord is required to maintain (and showing the Tenant Protected Parties as additional insured in the liability insurance policy only), which shall state that such insurance coverage may not be canceled without at least 30 days’ prior
written notice to Landlord. 
 Landlord may periodically, but not more often than every five (5) years, require that Tenant reasonably
increase the aforementioned coverage in a manner comparable to the increases requested by landlords of comparable office buildings in downtown Chicago. Except as provided to the contrary herein with respect to liability insurance, any insurance
carried by Landlord or Tenant shall be for the sole benefit of the party carrying such insurance. Any insurance policies hereunder may be “blanket policies.” 
 (H) Waiver of Subrogation and Release of Claims. Without limiting the generality of Article 26 hereof, by this Article Landlord and Tenant hereby 
 (i) agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property loss to the
extent that such coverage is required to be provided hereunder (ignoring, for this purpose, Paragraphs 11(C) and 11(F)) or is otherwise in effect (and, for this purpose, any applicable deductible or self-insured amount, subject to inclusion in
Operating Expenses to the extent permitted by Paragraph 3(B) above, shall be treated as though it were recoverable under such policies); and 
 (ii) waive to such extent all rights and claims against each other for such losses and all rights of subrogation of their respective insurers (with the exception of Workers’ Compensation Insurance). 

Landlord and Tenant agree that their respective insurance policies are now, or shall be, endorsed such that said waiver of subrogation shall not
affect the right of the insured to recover thereunder. 
  

 74 

 (I) Relationship to Article 4. Nothing in this Article 11 shall be deemed to limit any of the
rights and obligations of Landlord and Tenant under Article 4, including any rights of Tenant under Article 4 to recover any losses, costs or damages thereunder, or any right of Landlord under Article 4 to receive an assignment of any insurance
claims or insurance proceeds. 
 ARTICLE 12. 
 Condemnation 
 If the entire Building, or any part thereof which includes all or a substantial
part of the Premises, or access thereto, shall be taken or condemned by any competent authority for any public or quasi-public use or purpose, the Term of this Lease shall end upon and not before the date when the possession of the part so taken
shall be required for such use and, except as otherwise provided herein, without apportionment of the award to or for the benefit of Tenant. If any condemnation proceeding shall be instituted in which it is sought to take or damage any part of the
Building, the taking of which would render the operation of the Building economically unfeasible, Landlord shall have the right to terminate this Lease upon not less than one hundred eighty (180) days’ notice prior to the date of
termination designated in the notice, provided the leases of all other tenants in the Building are terminated. If this Lease is terminated pursuant to this Article, Rent at the then-current rate shall be apportioned as of the date of the termination
in the notice. If a portion of the Premises is taken or condemned by any competent authority for any public or quasi-public purpose or use and the Lease is not terminated pursuant to the foregoing provisions of this Article, then (a) from and
after the date when possession of such portion of the Premises is required for such use, the Net Rent and Rent under Article 3 shall be adjusted to reflect the reduced area of the Premises and the Building, and (b) Landlord shall promptly
repair the portion of the Premises not taken, but affected by such taking, including any required demising and separation work. Landlord shall be entitled to receive the entire award or payment in connection therewith, except that Tenant shall have
the right to file any claim available to Tenant under applicable Law for any taking of leasehold improvements paid for by Tenant and any Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the
Term and for moving expenses, provided that such separate award shall not reduce the award or judgment recoverable by Landlord. 
 If any
portion of the Property other than the Building is taken by condemnation or if the temporary use or occupancy of all or any part of the Premises shall be taken by condemnation during the Term, this Lease shall be and remain unaffected by such
condemnation, and Tenant shall continue to pay in full the Rent payable hereunder. In the event of any such temporary taking for use or occupancy of all or any part of the Premises, so long as Tenant does not exercise its right to terminate as
provided in the next sentence, Tenant shall be entitled to appear, claim, prove and receive the portion of the award for such taking that represents compensation for use or occupancy of the Premises during the Term and Landlord shall be entitled to
appear, claim, prove and receive the portion of the award that represents the costs of restoration of the Premises and the use or occupancy of the Premises after the end of the Term hereof. Notwithstanding the foregoing, if any temporary taking of
the Premises or any substantial portion thereof is reasonably anticipated to exceed one (1) year, Tenant shall have the right, by written notice to Landlord within sixty (60) days following the effective date of the temporary taking, to
terminate this Lease with respect to that portion of the Premises so taken, and Tenant shall not be entitled to any portion of the award for such taking. 
  

 75 

 For purposes of this Article 12 only, a substantial part or portion of the Premises shall be deemed
to mean not less than 25% of the square footage of Rentable Area of the Premises. 
 ARTICLE 13. 
 Return of Possession 
 At the
expiration or earlier termination of this Lease or Tenant’s right of possession, Tenant shall surrender possession of the Premises in good condition, ordinary wear and tear and damage by fire or other casualty or condemnation excepted, and
shall furnish Landlord with keys, key cards or other devices permitting access to the Building or the Premises and every portion thereof, and shall advise Landlord as to the combination of any locks or vaults then remaining in the Premises, and
shall remove all trade fixtures and personal property, with the exception of cables, wiring, conduit and pullboxes which Tenant may, but shall not have the obligation to, leave in the Premises. Tenant shall repair any damage caused by such removal.
Tenant shall have the right to remove any Tenant Work or Alteration Work prior to the expiration of this Lease, so long as Tenant repairs all damage caused by such removal. All Tenant Work and Alteration Work not so removed by Tenant prior to the
termination or expiration of this Lease, upon such termination or expiration, shall become Landlord’s property and shall remain upon the Premises, all without compensation, allowance or credit to Tenant. However, if prior to such termination or
expiration Landlord so directs by notice, Tenant shall promptly remove any Special Alterations which, pursuant to Article 8, Landlord reserved the right to require Tenant to remove, and Tenant shall repair any damage caused by such removal. In
no event shall Tenant be required to remove any internal staircase installed between floors of the Premises or to restore any stairwell holes relating thereto, to remove or repair any elevators installed between floors of the Premises, or any
modifications to the Base Building Work made to accommodate the installation of any such staircases or elevators. If Tenant shall fail to perform any removal, repair or restoration required under this Article 13, Landlord may do so, and Tenant
shall pay Landlord the reasonable out-of-pocket cost thereof upon demand. All property removed from the Premises by Landlord pursuant to any provisions of this Lease or any Law may be handled or stored by Landlord (at Tenant’s expense if Tenant
was required by this Lease to remove the same and failed to do so), and Landlord shall in no event be responsible for the value, preservation or safekeeping thereof. All property not removed from the Premises or retaken from storage by Tenant after
expiration or earlier termination of this Lease or Tenant’s right to possession, shall at Landlord’s option, upon delivery of five (5) Business Days’ prior written notice to Tenant of such abandonment unless so removed by Tenant
in such 5 Business Day period, be conclusively deemed to have been conveyed by Tenant to Landlord as if by bill of sale without payment by Landlord. 
  

 76 

 ARTICLE 14. 
 Holding Over 
 (A) Holding Over. Unless Landlord expressly agrees otherwise in writing,
Tenant shall pay Landlord as base net rent an amount equal to 150% of the monthly installments of Net Rent applicable immediately preceding Tenant’s holdover of possession of the Premises beyond the Term for the first ninety (90) days of
such holdover and thereafter 200% of monthly installments of Net Rent applicable immediately preceding Tenant’s holdover beyond the Term, and, together with, in both instances, 100% of all Additional Rent attributable to such Holdover Period,
in each case, prorated on a per diem basis for each day Tenant shall retain possession of the Premises or any part thereof after expiration or earlier termination of this Lease. The foregoing provisions shall not be deemed to limit or constitute a
waiver by Landlord of any rights of re-entry or other rights or remedies of Landlord provided herein or at law and shall not serve as permission for Tenant to hold over, nor serve to extend the Term (although after commencement of said holdover
Tenant shall remain bound to comply with all provisions of this Lease until Tenant vacates the Premises, and shall be subject to the provisions of Article 13). Notwithstanding the foregoing, the rental amounts set forth in this Article 14 have been
specifically negotiated by Landlord and Tenant to be, and the same shall be, Landlord’s sole monetary remedy on account of Tenant’s holding over in or retaining possession of the Premises or any part thereof, and in no event shall Landlord
be entitled to recover any other monetary damages or award, whether direct, indirect, special or consequential. 
 (B) Consensual
Holdover. Notwithstanding the provisions of Paragraph 14(A) to the contrary, if Tenant provides written notice to Landlord (a “Holdover Notice”) at least twenty-one (21) months prior to the Expiration Date, but no earlier
than thirty-six (36) months prior to the Expiration Date, and so long as Tenant is not then in monetary or material non-monetary Default, then the Expiration Date shall be extended for one (1) period of either six (6), twelve (12) or
eighteen (18) months as specified by Tenant in the Holdover Notice (the “Consensual Holdover Period”), which election, once made, shall be irrevocable by Tenant. Tenant’s use and occupancy of the Premises during the
Consensual Holdover Period shall be upon the same terms and conditions contained in this Lease, except that during the Consensual Holdover Period, Tenant shall be required to pay Landlord each month, as base rent, an amount equal to one hundred
twenty-five percent (125%) of the monthly installment of Net Rent applicable to the Premises in effect during the Term immediately preceding delivery of the Holdover Notice; except that if the Consensual Holdover Period is for eighteen
(18) months, then during the final six (6) months of the Consensual Holdover Period, the monthly base rent payable by Tenant to Landlord shall be equal to the product of one hundred twenty-five percent (125%) times one hundred and two
percent (102%) of the monthly installment of Net Rent applicable to the Premises in effect during the Term immediately preceding delivery of the Holdover Notice, in each case, together with one hundred percent (100%) of all Additional Rent
attributable to the Consensual Holdover Period. 
 ARTICLE 15. 
 No Waiver 
 No provision of this Lease will be deemed waived by either
party unless expressly waived in writing signed by the waiving party. No waiver shall be implied by delay or any other act or omission of either party. No waiver by either party of any provision of this Lease shall be deemed a waiver of such
provision with respect to any subsequent matter relating to such provision, and Landlord’s 

  

 77 

 
consent or approval respecting any action by Tenant shall not constitute a waiver of the requirement for obtaining Landlord’s consent or approval
respecting any subsequent action. Acceptance of Rent by Landlord shall not constitute a waiver of any breach by Tenant of any term or provision of this Lease or constitute a renewal or extension of the Term hereof. No acceptance of a lesser amount
than the Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. The acceptance of Rent or of the performance of any other term or provision from any person or entity other than
Tenant, including any Transferee, shall not constitute a waiver of Landlord’s right to approve any Transfer. 
 ARTICLE 16.

 Attorneys’ Fees and Jury Trial 
 In the event of any litigation between the parties, the prevailing party (as determined by the applicable judge) in the action or proceeding shall be entitled to obtain, as part of the judgment, all reasonable outside
attorneys’ fees, costs and expenses incurred in connection with such litigation, except as may be limited by applicable Law. In the interest of obtaining a speedier and less costly hearing of any dispute, the parties hereby each irrevocably
waive the right to trial by jury in any action or proceeding under or arising out of or related to this Lease or the Premises. 
 ARTICLE
17. 
 Personal Property Taxes, Rent Taxes and Other Taxes 
 Tenant shall pay prior to delinquency all taxes, charges or other governmental impositions assessed against or levied upon Tenant’s fixtures,
furnishings, equipment and personal property located in the Premises. Whenever possible, Tenant shall cause all such items to be assessed and billed separately from the property of Landlord. In the event any such items shall be assessed and billed
with the property of Landlord, Tenant shall pay Landlord its share of such taxes, charges or other governmental impositions within thirty (30) days after Landlord delivers a statement and a copy of the assessment or other documentation showing
the amount of such impositions applicable to Tenant’s property. The foregoing provisions of this Paragraph shall not apply to Tenant Work or to any Alteration Work. Any taxes, charges or other governmental impositions assessed against or
levied upon the fixtures, furnishings, equipment and personal property located in the Shared Facilities shall be a Shared Facilities Cost. 
 All taxes, charges or other governmental impositions assessed against or levied upon the fixtures, furnishings, equipment and personal property located at the Property of any other tenant shall be excluded from Taxes. The foregoing
provisions of this Paragraph shall not be applicable to any leasehold improvements of any such other tenant. 
  

 78 

 Tenant shall pay any rent tax, sales tax, service tax or value added tax on the Rent payable hereunder or
any other applicable tax on the services herein or otherwise respecting this Lease, to the extent such taxes are not included in Taxes or Operating Expenses pursuant to Article 3 above. 
 ARTICLE 18. 
 Entry by Landlord 
 Provided that Landlord provides Tenant with reasonable prior oral notice thereof (except in the case of an emergency in which case no notice shall be
required, but Landlord shall endeavor in good faith to provide prompt oral notice), Landlord may enter the Premises at all reasonable times (and Tenant shall have the right to have its representatives present) to: 
 (i) inspect the same; 
 (ii) Exhibit the same to prospective purchasers, Mortgagees or, during the last 567 days preceding the then Expiration Date, tenants; 
 (iii) determine whether Tenant is complying with all of its obligations under this Lease; 
 (iv) supply janitorial, cleaning and other services to be provided by Landlord to Tenant under this Lease; 
 (v)
make repairs in or to the Building or the Premises or improvements in or to the Building but not the Premises to the extent and in the manner permitted hereunder; 
 (vi) access any and all mechanical, electrical or other installations located in the Premises (and Tenant agrees that there shall be no
construction of partitions or other obstructions which might interfere with Landlord’s access to and the moving of its servicing equipment to or from the enclosures containing said installations); or 
 (vii) exercise its rights under Article 22. 
 Landlord also shall be permitted to enter the Premises without notice to perform the cleaning and trash removal services required pursuant to Paragraph 6(A)(iv) above. All janitorial, cleaning or other services and all maintenance, repairs
and improvements and all other work shall be done as promptly as reasonably possible and so as to cause as little interference to Tenant as reasonably possible and, except in the case of emergencies, Landlord shall use commercially reasonable
efforts (which shall include the payment of overtime wages) to cause any such maintenance, repairs and improvements and other work (other than changing of light bulbs and window washing) to be performed within any portion of the Premises shall be
done after Regular Business Hours, unless Tenant otherwise requests. Landlord at all times shall have and retain a key with which to unlock all of the doors in, on or about the 

  

 79 

 
Premises (excluding Tenant’s vaults, safes and similar areas designated by Tenant in writing in advance), and Landlord shall have the right to use
reasonable means to open such doors to obtain entry to the Premises, and any entry to the Premises obtained by Landlord by any such means, if done in accordance with the provisions of this Article, shall not under any circumstances be deemed or
construed to be a forcible or unlawful entry into or a detainer of the Premises or an eviction, actual or constructive, of Tenant from any part of the Premises, or act as a termination of Tenant’s duties under this Lease. 
 ARTICLE 19. 
 Subordination,
Nondisturbance and Attornment 
 (A) Subordination, Non-Disturbance and Attornment. Landlord may hereafter encumber the
Property or any part thereof with mortgages, may sell and lease back the Land, or any part of the Land, and may encumber the leasehold estate under such sale and leaseback arrangement with one or more mortgages (any such mortgage on the Property or
any part thereof or on any such leasehold estate is herein called a “Mortgage” and the holder of any such mortgage is herein called a “Mortgagee” and any such lease of the Land or any part of the Land is herein
called a “Ground Lease” and the lessor under any such lease is herein called the “Ground Lessor”). Landlord agrees to obtain from any Mortgagee and from any Ground Lessor, from time to time, a subordination,
non-disturbance and attornment agreement (“SNDA”) in a form no less favorable to Tenant in any material respect than the forms attached hereto as Exhibit L-1 (in the case of Mortgagees) and Exhibit L-2 (in
the case of Ground Lessors), which Tenant, no later than ten (10) days thereafter, shall execute and return to such Mortgagee or Ground Lessor; provided, however, that no such agreement shall be effective or binding on Tenant unless and until
the same shall be executed and delivered by such Mortgagee or Ground Lessor and Landlord. 
 (B) Subordination by Mortgagee.
Notwithstanding anything to the contrary contained herein, any Mortgagee or Ground Lessor may subordinate its Mortgage or Ground Lease, as the case may be, to this Lease by sending Tenant notice in writing subordinating such Mortgage or Ground Lease
to this Lease, and Tenant agrees to execute and deliver to such Mortgagee or Ground Lessor such further instruments consenting to or confirming the subordination of such Mortgage or Ground Lease to this Lease, which instruments shall be in form and
substance reasonably satisfactory to Tenant, within twenty-one (21) days after notice to Tenant of such request. 
 ARTICLE 20. 

 Estoppel Certificate 
 Tenant agrees at any time and from time to time upon not less than twenty one (21) days’ prior written notice from Landlord, to execute, acknowledge and deliver to Landlord an estoppel certificate in the form of
Exhibit M attached hereto (the “Tenant Estoppel Certificate”). The Tenant Estoppel Certificate shall be addressed to Landlord and, if Landlord shall so request, to any current or 

  

 80 

 
prospective Mortgagee or any assignee thereof, any prospective purchaser of the Land, improvements or both comprising the Property, and any other party
Landlord may reasonably request. In addition, the Tenant Estoppel Certificate may be modified to contain certifications, to the best of Tenant’s knowledge, of such reasonable, non-confidential factual matters not set forth in Exhibit M as
may be reasonably requested by the intended addressees. Any Tenant Estoppel Certificate delivered pursuant to this Article may be relied upon by each party to whom it is addressed and the Tenant Estoppel Certificate, if required by its
addressee(s), may so specifically state. 
 Landlord agrees at any time and from time to time upon not less than twenty-one
(21) days’ prior written notice from either Tenant or a Transferee under any Exempt Transfer, to execute, acknowledge and deliver to Tenant or such Transferee an estoppel certificate in the form of Exhibit N attached hereto
(the “Landlord Estoppel Certificate”). The Landlord Estoppel Certificate shall be addressed to Tenant and/or such Transferee and, if Tenant or such Transferee shall so request, to any current or prospective assignee of this Lease or
subtenant of all or any portion of the Premises (provided such assignment or sublease transaction to which such Landlord Estoppel Certificate relates is permitted or consented to by Landlord pursuant to the terms of Article 21 below) or any other
party Tenant or such Transferee may reasonably request. In addition, the Landlord Estoppel Certificate may be modified to contain certifications, to the best of Landlord’s knowledge, of such reasonable, non-confidential factual matters not
expressly set forth in Exhibit N as may be reasonably requested by the intended addressees. Any Landlord Estoppel Certificate delivered pursuant to this Article may be relied upon by each party to whom it is addressed and the Landlord
Estoppel Certificate, if required by its addressee(s), may so specifically state. 
 ARTICLE 21. 
 Assignment and Subletting 
 (A)
Transfers. Except as provided in Paragraph 21(C) below, Tenant shall not have the right, without the prior written consent of Landlord, to: (i) assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or
otherwise transfer, directly or indirectly, this Lease or any interest hereunder, by operation of law or otherwise, (ii) sublet the Premises or any part thereof, or (iii) otherwise permit the use of the Premises by any persons other than
Tenant (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a
“Transferee”). If Tenant shall desire Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice shall include: (a) the proposed effective or commencement date (which shall not be less than
thirty (30) days after Tenant’s notice) and, except in the case of an assignment, the proposed expiration date and the portion of the Premises to be Transferred (herein called the “Subject Space”), (b) the name and
address of the proposed Transferee, (c) the purposes for which the proposed Transferee intends to use the Premises or the Subject Space, and (d) in the case of an assignment, (x) current financial statements of the proposed Transferee
certified by an officer, partner or owner thereof, and (y) such other information regarding the proposed Transfer and the proposed Transferee as Landlord may reasonably require. Any Transfer made without complying with this Article shall,
at Landlord’s option, be null, void and of no effect, and/or, after the lapse of the applicable cure period, shall constitute a Default. 
  

 81 

 (B) Consent. Notwithstanding the provisions of Paragraph 21(A), Landlord shall not
unreasonably withhold its consent to a proposed Transfer (provided, however, Landlord in its sole and absolute discretion shall have the right to withhold consent to any mortgage, pledge, hypothecation, or encumbrance of this Lease or any lien,
claim or other encumbrance upon Tenant’s right, title or interest under this Lease). Tenant agrees that Landlord shall be acting reasonably in withholding its consent if any one or more of the following applies: 
 (i) the Transferee is of a character or reputation or engaged in a business which will damage the reputation of the Building, 

(ii) the Transferee intends to use the Premises or the Subject Space for purposes which are not permitted under this Lease or for a
Prohibited Use, 
 (iii) the Transferee is a government (or agency or instrumentality thereof), 
 (iv) a monetary Default or material non-monetary Default has occurred and is then continuing at the time Tenant requests consent to the
proposed Transfer, or 
 (v) the Transferee is in active negotiations with Landlord for space in the Building. 
 Landlord’s consent shall be set forth in an instrument in the form of Exhibit O-1 (in the case of an assignment) or Exhibit O-2 (in the case
of a sublease or occupancy) and shall not be effective until such instrument has been countersigned by Tenant and the assignee, subtenant or occupant. Tenant agrees to pay to Landlord, on demand, all reasonable out-of-pocket costs incurred by
Landlord payable to third parties in connection with any request by Tenant for Landlord to consent to Transfer by Tenant. 
 (C) No
Consent Required. The initial Tenant under this Lease shall have the right to sublease to its Affiliates any or all of the Premises. Landlord shall provide, and shall cause any Mortgagee or Ground Lessor to provide, a recognition agreement, in
form and substance satisfactory to Landlord and Tenant, in favor of any subtenant which is an Affiliate of the initial Tenant and subleases more than 15,000 square feet of Rentable Area of the Premises. Such recognition agreement shall provide that
the rights of any such subtenant under such sublease shall not be disturbed on account of any Default, or in the event a Mortgagee or Ground Lessor shall succeed to the rights and estate of Landlord, so long as such subtenant pays the portion of the
Rent applicable to the portion of the Premises subleased to it. In addition, provided no monetary Default or material non-monetary Default has occurred and is then continuing at the time of the effective or commencement date of the Transfer, Tenant
may, at any time and from time to time, without the prior consent of Landlord but with prior notice to Landlord, assign this Lease or any interest hereunder to, or sublease the Premises or any part thereof to, or permit the occupancy of the
Premises, or any part thereof by, 
 (i) any successor entity of Tenant resulting from a merger or consolidation with Tenant,

  

 82 

 (ii) any entity succeeding to all or substantially all of the business and assets of
Tenant, 
 (iii) any entity which, at the effective or commencement date of the Transfer, is an Affiliate of Tenant,

 (iv) any entity which, at the effective or commencement date of such Transfer, is acquiring all or a bona fide portion of
the business being conducted at the Premises by Tenant or its Affiliates, or 
 (v) any service provider, client or customer
of Tenant or any Affiliate; provided, however, that (a) no assignment shall be made pursuant to this clause (v), and (b) the aggregate Rentable Area subject to sublease or occupancy under this clause (v) at any time shall not exceed
twenty-five percent (25%) of the Premises 
 (any such Transfer being herein referred to as an “Exempt Transfer”). An
“Affiliate” of any person is another person that directly or indirectly through one or more intermediaries controls, is controlled by or is under common control with the first person. The word “control” shall mean the
power, directly or indirectly, by voting rights, contract or otherwise, to direct or cause the direction of the management or policies of a person. For purposes of this Lease, CC-Development Group, Inc., Pritzker Realty Group, L.P., The Pritzker
Organization, L.L.C., Diversified Financial Management Corp., and H Group Holding, Inc. shall be deemed to be Affiliates. Notwithstanding anything contained in this Paragraph 21(C) to the contrary, 
  

	 	(1)	no assignment or sublease permitted pursuant to this Paragraph 21(C) shall violate any of the conditions set forth in Paragraph 21(B)(ii) or (iii),

  

	 	(2)	any such assignee or subtenant under clauses (i) or (ii) of this Paragraph 21(C) shall, immediately after the effective or commencement date of such Transfer, have a
tangible net worth, determined in accordance with GAAP, equal to or greater than 40 times the Net Rent per annum then payable under this Lease, 

  

	 	(3)	any such assignee shall expressly assume all of Tenant’s obligations and liabilities hereunder without releasing the assignor or the guarantor, if any,

  

	 	(4)	any sublease shall by its terms be expressly subordinate to all of the terms, covenants and conditions of this Lease, subject to the rights of such subtenant under any recognition
agreement, and 

  

 83 

	 	(5)	Tenant shall deliver to Landlord promptly after the effective or commencement date thereof evidencing that the Transfer is an Exempt Transfer, together with a copy of the
assignment, sublease, or occupancy agreement; provided, however, that any sublease or occupancy agreement pursuant to clause (iii) of this Paragraph 21(C) which is terminable at will by Tenant may be unwritten, so long as the Transferee
remains an Affiliate of Tenant (in which case, in lieu of providing a copy of a written instrument, Tenant shall confirm such fact to Landlord). 

 (D) Terms of Consent. If Landlord consents to a Transfer effected under Paragraph 21(B) above: (a) the terms and conditions of this Lease, including among other things, Tenant’s liability for the
Premises or the Subject Space, shall in no way be deemed to have been waived or modified, (b) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (c) any assignee (but not any subtenant other
than as provided in Paragraph 21(C)) shall succeed to all rights provided to Tenant in this Lease, including, without limitation, the right to extend the Term of this Lease, to expand the Premises, or to lease additional space, (d) any
subtenant shall have the same rights and obligations with respect to an assignment of its sublease and/or undersubletting as Tenant has with respect to an assignment of this Lease and/or subletting, except to the extent that the sublease shall
impose additional restrictions or obligations, (e) Tenant shall deliver to Landlord promptly after execution, an original executed copy of all documentation pertaining to such Transfer, and (f) Tenant shall furnish in respect of each
calendar year all or any part of which falls within the term of such sublease other than a sublease under Paragraph 21(C), a complete statement, certified by an authorized employee of Tenant with knowledge of the relevant facts, setting forth
in detail the computation of any profit derived by Tenant during such calendar year from such Transfer. Such statement for any such calendar year shall be furnished no later than 60 days after Tenant’s receives Landlord’s Statement under
Paragraph 3(C)(iii) for such calendar year. Landlord or its authorized representative shall have the right at all reasonable times to audit the books, records, and papers of Tenant relating to any Transfer, and shall have the right to make
copies thereof. If the profit respecting any Transfer shall be found to have been understated, Tenant, within thirty (30) days after demand, shall pay the deficiency, and if understated by more than 5%, Tenant shall pay Landlord’s costs of
such audit. Any sublease hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any sublease, Landlord shall have the right to: (i) treat such sublease as canceled
and repossess the Subject Space by any lawful means, or (ii) require that such subtenant attorn to and recognize Landlord as its landlord under any such sublease. If Tenant is in monetary or material non-monetary Default under this Lease,
Landlord is hereby irrevocably authorized, as Tenant’s agent, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this
Lease) until such Default is cured. 
  

 84 

 (E) Profits. Tenant shall pay to Landlord, when and as received by Tenant, after recovery of all
of Tenant’s Associated Costs, an amount equal to 50% of all profit derived by Tenant from any subletting of the Premises or assignment of this Lease that is not permitted under Paragraph 21(C). For purposes of the foregoing,
“profit” shall mean all rent or other compensation paid by such sublessee or assignee in excess of Rent payable by Tenant under this Lease allocable to the Premises or the Subject Space, less the Associated Costs. The term
“Associated Costs” shall mean the actual, out-of-pocket expenses and costs of Tenant incurred to induce or otherwise related to such subleasing or assignment, including, but not limited to, marketing and brokerage costs, reasonable
outside attorney’s fees and expenses, cash inducements, construction and reconstruction costs, rent subsidies, lease assumption costs, moving allowances, and Rent allocable to the subleased premises (or the Premises in the case of an
assignment) for any period (i) after the date on which Tenant engages the services of a licensed broker pursuant to a written commission agreement to facilitate the subleasing of such subleased space or the assignment of this Lease,
(ii) during which Tenant (or such broker) shall be actively engaged in the marketing of such subleased space (or the Premises in the case of the assignment) and (iii) after the date on which Tenant ceases using such subleased space (or the
Premises in the case of an assignment) for any substantial business purpose other than storage. 
 (F) Non-Waiver. The consent by
Landlord to any Transfer shall not relieve Tenant, or any person claiming through or by Tenant, of the obligation to obtain the consent of Landlord, pursuant to this Article 21, to any further Transfer to the extent otherwise herein required.
Any Transfer hereunder shall not release or discharge Tenant of or from any liability, whether past, present or future, under this Lease, and Tenant shall continue fully liable thereunder. 
 (G) Recapture. In the event that, at any time prior to the fifth (5th) anniversary of the MB Commencement Date, Tenant
proposes to sublease all or any part of the High-Rise Premises for the remainder of the initial Term, and such proposed sublease is not an Exempt Transfer, Landlord shall have the right, exercisable within fifteen (15) days of its receipt of
such notice, to terminate this Lease with respect to the space intended to be subleased, subject to the terms set forth in this Paragraph 21(G). Landlord may exercise such right by notice given to Tenant within such fifteen (15) day period and,
if Landlord does not exercise such right within the applicable period, Tenant, subject to Paragraph 21(A) above, may proceed with such sublease. If Landlord does exercise such right to terminate, such termination shall be effective, subject to the
provisions of this Paragraph 21(G) on the later of the proposed effective date of such sublease set forth in Tenant’s notice to Landlord or the Revocation Date (as hereinafter defined), unless otherwise agreed by Landlord and Tenant.
Notwithstanding the foregoing, if Landlord exercises such right to terminate as herein provided, Tenant may, at its election, exercisable by notice given to Landlord within thirty (30) days of Landlord’s notice to Tenant exercising such
right to terminate (the “Revocation Date”), revoke its initial notice of such proposed sublease, in which event Landlord’s exercise of its right to terminate shall be null and void and of no force or effect. In the event that
this Lease is terminated with respect to all or any portion of the High-Rise Premises, the Net Rent due and payable hereunder shall be reduced by an amount per annum equal to the product obtained by multiplying (i) the number of square feet of
Rentable Area in the portion of the High-Rise Premises so recaptured, and (ii) the Allocated High-Rise Premises Net Rent. As used herein, the “Allocated High-Rise Premises Net Rent” shall mean (i) in respect of the
46th floor, an amount, expressed on a per square foot of Rentable Area basis, equal
to $32.50 for the first Lease Year, increased by 2% per annum in each succeeding Lease Year, and (ii) in respect of the 47th and 48th
 floors, an amount, expressed

on a per square foot of Rentable Area basis, equal to $27.67 for the first Lease Year, increased by two percent (2%) per annum in each succeeding Lease
Year. In the event that this Lease is terminated with respect to all or any part of the High-Rise Premises pursuant to the provisions of this Paragraph 21(G), such termination shall not affect any of the rights or obligations of the parties
hereunder with respect to the remainder of the Premises. If the recaptured space is only a part of a floor of the High-Rise Premises, Landlord shall construct and finish in accordance with Building standards all corridors, elevator lobbies and other
common areas on the floor required for the same to be occupied as a multi-tenant floor. 
 (H) Restrictions on Transfer of High-Rise
Premises. Notwithstanding anything to the contrary herein contained, prior to the fifth anniversary of the MB Commencement Date, Tenant shall not be permitted to Transfer all or any portion of the High-Rise Premises, other than pursuant to an
Exempt Transfer, to any legal services provider that, at the time of such Transfer, is included as one of the one hundred largest legal services providers as then most recently ranked by the American Lawyer magazine (or other similar publication).
As used herein, the term “MB Commencement Date” shall mean the “Commencement Date” as defined in the Mayer Brown Lease. 
 ARTICLE 22. 
 Certain Rights Reserved By Landlord 
 Landlord shall have the following rights, exercisable without notice (except as expressly provided) and without effecting an eviction, constructive or
actual, or disturbance of Tenant’s use or possession or giving rise to any claim for set-off or abatement of Rent: 
 (A) To require
that all of Tenant’s window shades, blinds, drapes, and other similar window coverings conform to the building standard specifications therefor as the same shall be jointly developed and agreed upon by Landlord and Tenant. This
Paragraph 22(A), however, shall not be applicable to any inner shades, blinds, drapes or window coverings which are in front of (as viewed from within the Premises) the blinds, shades, drapes or window coverings conforming to the building
standard specifications, provided such inner shades, blinds, drapes or window coverings are not visible from outside of the Building. Landlord shall enforce said building standard specifications uniformly against all tenants and occupants of the
Building. 
 (B) To decorate or to make alterations, additions, or improvements, structural or otherwise, in or to the Property, or any part
thereof, and any adjacent building, structure, parking facility, land, street or alley (including without limitation changes and reductions in corridors, lobbies, parking facilities and other Common Areas and the installation of planters,
sculptures, displays, escalators, mezzanines, and other structures, facilities, amenities and features therein, and changes for the purpose of connection with or entrance into or use of the Property in conjunction with any adjoining or adjacent
building or buildings, now existing or hereafter constructed); provided, that, 
  

 86 

 (i) none of such alterations, additions, or improvements shall (a) be located in the
Premises or (b) materially and adversely affect the Franklin Street entrance to the Building (the “Franklin Entrance”) or the Wacker Drive entrance to the Building (the “Wacker Entrance” and, together with the
Franklin Entrance, the “Pedestrian Entrances”), the layout of the ground floor (other than any retail areas along the northern wall of the Building), any of the elevators, escalators or stairways serving the Premises or the Shared
Facilities, (c) affect Tenant’s signage, (d) adversely affect the security of the Building or any portion thereof or (e) be such that Tenant would have been entitled to withhold its consent thereto pursuant to the Workletter if
the same had been included in Landlord’s Work; 
 (ii) there will not be any increase in Net Rent, Additional Rent or
Tenant’s Pro Rata Share on account thereof, 
 (iii) no alterations to the low mid-rise or high-rise elevator lobby on
the ground floor of the Building shall be made (other than such alterations having a de minimis effect thereon), without the prior written approval of Tenant, which shall not be unreasonably withheld, and 
 (iv) no mezzanine shall be constructed in the ground floor lobby nor shall the height of any portion thereof be reduced; 
 provided, however, that after the Rent Commencement Date the provisions of clauses (i), (iii) and (iv) shall be subject to Landlord’s obligations to keep
the Base Building Work in compliance with all Laws pursuant to Paragraph 9(B) above. In connection with such matters, or with any other repairs, maintenance, improvements or alterations in or about the Property, Landlord may erect scaffolding and
other structures reasonably required, and may temporarily close public entryways, other public areas, restrooms, stairways or corridors, so long as Tenant continues to have access to the Premises at all times (subject to Paragraph 22(E)).
Landlord shall take commercially reasonable steps to minimize any interference with Tenant’s operations resulting from any actions taken by Landlord under this Paragraph 22(B). All work in the Premises (and all other work which would cause
any material interference with Tenant’s business if performed during Regular Business Hours) shall be performed outside of Regular Business Hours. 
 (C) To approve (such approval not to be unreasonably withheld) the weight, size and location of safes and other heavy equipment and bulky articles in and about the Premises and the Building (so as not to overload the
floors of the Premises), and to require all such items to be moved into and out of the Building and Premises only at such times and in such manner as Landlord shall reasonably direct. Furniture, boxes, merchandise or other bulky articles shall be
transported within the Building only upon or by vehicles equipped with rubber tires and, except as otherwise provided in Article 6, shall be carried only in the freight elevators. 
 (D) To temporarily (i) limit or prevent access to the Property, (ii) shut down elevator service, (iii) activate elevator emergency
controls, or (iv) take other actions (including preventive measures) as are deemed necessary by Landlord for the safety of tenants or other occupants of the Property or the protection of the Property and other property located thereon or
therein 
  

 87 

	 	(1)	in case of fire, invasion, insurrection, riot, civil disorder, terrorist act, public excitement or other dangerous condition, or threat thereof, or 

  

	 	(2)	in order to perform any maintenance or repairs which requires a Building closure; 

 provided, however, that (except in emergencies) Landlord shall give Tenant at least ten (10) Business Days prior written notice of Landlord’s intention to close the Building pursuant to clause (2) (and, except in case of an
emergency, Landlord agrees to restrict any such closure pursuant to clause (2) to Saturday, Sunday or Holidays). Tenant shall have the right (but only once with respect to any particular closure), by written notice given to Landlord within
three (3) Business Days after Tenant’s receipt of such notice from Landlord, to require Landlord to postpone such closure for up to fifteen (15) Business Days beyond the date set forth in Landlord’s notice. 
 (E) To install and maintain pipes, ducts, and conduits above the hung ceiling of the Premises or in the columns or shafts in the Premises to serve other
parts or other tenants of the Building; provided that (i) except for pipes installed as a part of Base Building Work, all pipes, ducts and conduits shall be installed in the columns or shafts of the Premises, (ii) no reduction in the
usable area of the Premises results therefrom, (iii) such installation and maintenance does not unreasonably interfere with Tenant’s use of the Premises for the conduct its business and other rights and benefits under this Lease, and
(iv) any damage caused thereby to the Premises or Tenant’s property is promptly repaired at Landlord’s expense. All such work in the Premises (and, to the extent commercially reasonable [which shall include the payment of overtime
wages], all other work which would cause any material interference with Tenant’s business if performed during Regular Business Hours) shall be performed outside of Regular Business Hours. 
 ARTICLE 23. 
 Tenant Default and Landlord Remedies 
 (A) Default by Tenant. Each of the following shall constitute a “Default” by Tenant, and shall give rise to Landlord’s
remedies set forth in Paragraph (b) below: 
 (i) failure by Tenant to make when due any payment of Rent and the
continuation of such failure for ten (10) days after notice; 
 (ii) failure by Tenant to observe or perform any of the
terms or conditions of this Lease to be observed or performed by Tenant other than the payment of Rent, or as provided below, and the continuation of such failure for thirty (30) days after notice (provided, that if the nature of Tenant’s
failure is such that more time is reasonably required in order to cure and Tenant commences to cure within such thirty (30) day period, then such period shall be extended so long as Tenant is diligently pursuing such cure to completion);

  

 88 

 (iii) failure by Tenant to comply with the Rules, and the continuation of such failure
for thirty (30) days after notice (provided, that if the nature of Tenant’s failure is such that more time is reasonably required in order to cure and Tenant commences to cure within such thirty (30) day period, then such period shall
be extended so long as Tenant is diligently pursuing such cure to completion); 
 (iv)(a) the making by Tenant of any
general assignment for the benefit of creditors, (b) the filing by or against Tenant of a petition to have Tenant adjudged a bankrupt or a petition for reorganization or arrangement under any Law relating to bankruptcy (unless, in the case of a
petition filed against Tenant, the same is dismissed within ninety (90) days), (c) appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located on the Premises or of Tenant’s interest in
this Lease, where possession is not restored to Tenant within ninety (90) days, (d) attachment, execution or other judicial seizure of substantially all of Tenant’s assets located on the Premises or of Tenant’s interest in this
Lease, or (e) Tenant’s admitted insolvency or admission of an inability to pay its debts as they mature; or 
 (v) a
Transfer of this Lease, or the Premises or any part thereof, in violation of Article 21 which is not cured within thirty (30) days thereafter. 
 The notice and cure periods provided herein are in lieu of, and not in addition to, any notice and cure periods provided by Laws. To the extent that any of the foregoing notice periods provided for in this
Article 23 and elsewhere in this Lease are greater than the notice periods required under the statutes of the State of Illinois, such greater notice periods as are provided for herein shall substitute for any such statutory notice periods, and,
to the extent not prohibited by such statutes, any notices given pursuant to the terms hereof shall be deemed the notice required by any such statutes. 
 (B) Remedies. If a Default has occurred and is continuing, Landlord shall have the rights and remedies hereinafter set forth, each of which shall be distinct, separate and cumulative with and in addition to any
other right or remedy allowed under any Law and/or other provisions of this Lease, any and all of which may be exercised with or without further notice and with or without demand whatsoever, concurrently or successively, and at such time or times
and in such order as Landlord may from time to time determine: 
 (i) Landlord may terminate this Lease and repossess the
Premises by detainer suit, summary proceedings or other lawful means, and recover from Tenant as damages an amount of money equal to the sum of: (a) any unpaid Rent as of the termination date, including interest at the Default Rate,
(b) any unpaid Rent which would have accrued after the termination date through the time of award, including interest at the Default Rate, (c) the present value of any unpaid Rent which would have accrued after the time of award during the
balance of the Term, less the present value of the fair market rental value of the Premises for such period, after deduction from the said fair market rental value of the Premises the Costs of Reletting (as defined in Paragraph (E) below of
this Article 23) for such balance of the Term (such net amount not to be less than zero in any event, it being the intention of the parties that Landlord shall have no obligation to pay to Tenant or to offset against other sums Tenant owes to
Landlord the excess, if any, of the present value of fair market rental value over the present value of said unpaid Rent), 

  

 89 

 
and (d) any other amounts necessary to compensate Landlord for all direct damages and other out-of-pocket losses, costs, and expenses caused by
Tenant’s failure to perform its obligations under this Lease to the extent such amounts are not included in the above. For purposes of computing the amount of Rent herein that would have accrued after the time of award, Tenant’s Pro Rata
Share of Taxes and Operating Expenses, shall be projected, based upon the average rate of increase, if any, in such items from the Commencement Date through the time of award. Present value shall be computed on the basis of a discount rate equal to
the then-current yield on United States Treasury obligations as reported in the Wall Street Journal or similar financial publication having a maturity approximately equal to the residue of the Term as determined by Landlord; provided, if no such
obligations of such maturity exist, then such discount rate shall be established by Landlord. 
 (ii) Landlord may terminate
Tenant’s right of possession and repossess the Premises by detainer suit, summary proceedings or other lawful means, without terminating this Lease (and if applicable Law permits, and Landlord shall not have expressly terminated the Lease in
writing, any termination shall be deemed a termination of Tenant’s right of possession only), in which event Landlord shall use commercially reasonable efforts to mitigate its damages by attempting to relet all or any part of the Premises to a
Replacement Tenant, for such rent and upon such terms as shall be satisfactory to Landlord (including the right to relet the Premises for a term greater or lesser than that remaining under the Term of this Lease and the right to relet the Premises
as a part of a larger area and the right to change the character or use made of the Premises). For the purpose of such reletting, Landlord is authorized to decorate or to make any repairs, changes, alterations or additions in or to the Premises that
may be necessary or convenient. In such event, Landlord may recover from Tenant the sum of: (a) any unpaid Rent as of the date possession is terminated, including interest at the Default Rate, (b) any unpaid Rent which accrues during the
Term from the date possession is terminated through the time of award (or which may have accrued from the time of any earlier award or awards obtained by Landlord through the time of the subsequent award or awards), including interest at the Default
Rate, less any Net Re-Letting Proceeds (as defined in Paragraph 23(E)) received by Landlord during such period, (c) all Rent from time to time which accrues from and after the date of the award and less any Net Re-Letting Proceeds received
by Landlord during such period, and (d) any other amounts necessary to compensate Landlord for all direct damages caused by Tenant’s failure to perform its obligations under this Lease to the extent such amounts are not included in the
above. Landlord may bring suits for such amounts or portions thereof, at any time or times as the same accrue or after the same have accrued, and no suit or recovery of any portion due hereunder shall be deemed a waiver of Landlord’s right to
collect all amounts to which Landlord is entitled hereunder, nor shall the same serve as any defense to any subsequent suit brought for any amount not theretofore reduced to judgment. 
 Without limiting the generality of the introduction sentence of this Paragraph 23(B), an election by Landlord to terminate Tenant’s right to possession of all or any part of the Premises or exercise any one
or more of its other rights and remedies, without terminating this Lease, shall not preclude a subsequent election by Landlord to terminate this Lease. 
  

 90 

 (C) Specific Performance, Collection of Rent and Acceleration. Landlord and Tenant shall each at
all times have the rights and remedies (which shall be cumulative with each other) provided by applicable Law or this Lease, without prior demand or notice except as required by applicable Law or this Lease, including without limitation the right to
seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. 
 (D) Interest. Any Rent paid after it is due shall accrue interest from the due date at the Default Rate, until payment is received by Landlord, except that the first late payment in any twelve (12) month
period shall accrue interest from the date that is five (5) days after the date of Landlord’s notice to Tenant of such non-payment. Such interest payments and late charges shall not be deemed consent by Landlord to late payments, nor a
waiver of Landlord’s right to insist upon timely payments at any time, nor a waiver of any remedies to which Landlord is entitled as a result of the late payment of Rent. 
 (E) Certain Definitions. “Net Re-Letting Proceeds” shall mean the total amount of rent and other consideration paid by any
Replacement Tenants, less all Costs of Re-Letting, during a given period of time. “Costs of Re-Letting” shall include, without limitation, all costs and expenses incurred by Landlord for any repairs, maintenance, changes,
alterations and improvements to the Premises, brokerage commissions, advertising costs, reasonable attorneys’ fees, any customary free rent periods or credits, tenant improvement allowances, take-over lease obligations and other customary,
necessary or appropriate economic incentives required to enter leases with Replacement Tenants, amortized with interest over the terms of the leases to such Replacement Tenants. “Replacement Tenants” shall mean any persons not
affiliated with Landlord to whom Landlord re-lets the Premises or any portion thereof pursuant to this Article. “Default Rate” shall mean the lower of (i) the sum of (x) the rate per annum equal to the rate of interest
announced from time to time by BankOne, N.A., or its successor, as its corporate prime or base rate of interest (such rate to change from time to time as and when such corporate prime or base rate changes) (the “Prime Rate”) plus
(y) four percent (4%), or (ii) the highest rate permitted by applicable Law. 
 (F) Removal. Any and all property that may
be removed from the Premises by Landlord pursuant to the authority of this Lease or at Law, to which Tenant is or may be entitled, may be handled, removed, or stored in a commercial warehouse or otherwise by Landlord (at Tenant’s risk, costs,
and expense if Tenant was required but failed to remove the same from the Premises), and Landlord shall in no event be responsible for the value, preservation, or safekeeping of that property. Tenant shall pay to Landlord, upon demand, any and all
expenses incurred for the removal or storage of any such property which Tenant was required but failed to remove as long as the same shall be in Landlord’s possession or under the Landlord’s control. Any property of Tenant not removed from
the Premises or retaken from storage by Tenant within thirty (30) days after the end of the Term shall be conclusively presumed to have been abandoned by Tenant unless Tenant removes such items within ten (10) days after written demand
therefor from Landlord. 
  

 91 

 (G) Landlord Action. If Tenant at any time fails to make any payment or perform any other act on
its part required to be made or performed under this Lease, and, except in the case of an emergency, such failure shall not be remedied within twenty (20) days after notice thereof to Tenant, Landlord may, but shall not be obligated to, after
reasonable notice to Tenant and without waiving or releasing Tenant from any obligation under this Lease, make such payment or perform such other act to the extent Landlord may deem desirable and in that connection pay reasonable expenses and employ
counsel. 
 (H) Other Matters. No re-entry or repossession, repairs, changes, alterations and additions, re-letting, acceptance of
keys from Tenant, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or accept a surrender of the Premises, nor shall the same operate to release
the Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by Landlord or its agent to Tenant. To the fullest extent permitted by Law, all rent and other consideration paid
by any Replacement Tenants shall be applied: first, to the Costs of Re-Letting, second, to the payment of any Rent theretofore accrued, and the residue, if any, shall be held by Landlord and applied to the payment of other obligations of Tenant to
Landlord as the same become due (with any remaining residue to be retained by Landlord). Landlord may apply payments received from Tenant to any obligations of Tenant then accrued, without regard to such obligations as may be designated by Tenant.
The times set forth herein for the curing of Defaults by Tenant are of the essence of this Lease. Tenant hereby irrevocably waives any right otherwise available under any Law to redeem or reinstate this Lease. 
 ARTICLE 24. 
 Landlord Default
and Tenant Remedies; Untenantability; Tenant Offset 
 (A) Landlord Default and Tenant’s Remedies. 
 (i) If any act or omission of Landlord would give Tenant the right, immediately or after lapse of a period of time, to cancel or terminate
this Lease (other than pursuant to a right of cancellation or termination expressly set forth in this Lease) or to abate or offset against payment of Rent (other than a right of abatement or offset expressly set forth in this Lease) or to claim a
partial or total eviction, Tenant shall not be entitled to exercise such right, unless such act or omission shall have continued unremedied for thirty (30) days after written notice thereof is given to Landlord and each Mortgagee or Ground
Lessor notice of the name and address of which shall have been previously given to Tenant; provided that, if more than thirty (30) days are reasonably required to effect such remedy and Landlord or any such Mortgagee or Ground Lessor commences
to remedy such act or omission within thirty (30) days after receipt of Tenant’s notice thereof, then such period shall be extended so long as Landlord or such Mortgagee or Ground Lessor are diligently prosecuting such remedy to
completion. The aforementioned periods of time permitted for Landlord to cure shall be extended for any period of time during which Landlord or any Mortgagee or Ground Lessor is delayed in, or prevented from, curing due to Unavoidable Delays.

  

 92 

 (ii) For purposes of this Lease, “Unavoidable Delays” shall mean delays
or interruptions caused by strikes, lockouts, failure of power, restrictive governmental laws or regulations not in effect as of the date of execution of this Lease, condemnations, riots, insurrections, acts of terrorism, war, fire, or other
casualty, acts of God, or other reasonably unforeseeable reasons not within the control of the party delayed in performing work or doing acts required under the terms of this Lease or its agents. Notwithstanding the foregoing, lack of money,
financial inability, reasonably foreseeable governmental action or inaction or failure to order long-lead items sufficiently in advance of the time needed shall not be Unavoidable Delays. Whenever this Lease provides that a time or period shall be
subject to extension for Unavoidable Delays, it shall be a condition of the right to claim an extension of time as a result of an Unavoidable Delay that the party seeking such extension shall notify the other party within five (5) days after
such party has knowledge of the existence of the Unavoidable Delay(s) specifying the nature and (to the extent known) the estimated length thereof. 
 (B) Untenantability. 
 (i) If the Premises or any portion thereof become Untenantable and such
Untenantability continues more than three (3) days (which three day period shall not be extended for Unavoidable Delays) after Tenant shall have given notice thereof to Landlord and any Mortgagee or Ground Lessor which is a party to an SNDA
with Tenant, then Rent shall abate with respect to the Premises or such portion thereof commencing on the first Business Day after such three-day period, and such abatement shall continue for the duration of such Untenantability. Landlord agrees at
all times to use diligent efforts to correct any Untenantability of the Premises. 
 (ii) If any period of Untenantability
involving more than fifty percent (50%) of the Rentable Area of the Premises continues for more than 180 consecutive days (without, except as provided below, any extension for Unavoidable Delays) after Tenant shall have given notice thereof to
Landlord and any Mortgagee or Ground Lessor which is a party to an SNDA with Tenant, Tenant shall have the right (during the period the Untenantability persists beyond the foregoing 180-day period), but exercisable only by written notice to Landlord
within the fifteen (15) day period following said 180 consecutive day period, to terminate this Lease, which termination shall be effective upon receipt of such written notice; provided, however, if the remediation of such Untenantability
requires work by Landlord which is not reasonably susceptible of being performed within such 180-day period then, if Landlord shall have commenced such remediation within such period and shall have diligently prosecuted such remediation, such
180-day period shall be extended for such additional period (beyond the initial 180-day period) as may be required for Landlord to remedy such Untenantability but not for more than sixty (60) days after such 180-day period. 
 (iii) For purposes of this Lease (including Article 10), “Untenantable” and “Untenantability” shall
mean with respect to the Premises, or any portion thereof, that the same cannot reasonably be used by Tenant for the normal conduct of its business and in accordance with applicable Laws, and in fact is not being so used for any purpose other than
storage, including by reason of (a) the condition of the Premises, or applicable portion thereof, (b) lack of access, electricity, HVAC, or other services, or 

  

 93 

 
(c) any failure of the air quality in the Premises to meet applicable governmental standards; provided, however, Untenantability shall not arise
(i) by reason of lack of access so long as elevator service is being provided by one or more of the passenger elevators, (ii) except for purposes of Article 10, if such circumstances are caused by any act or omission of Tenant, its
employees, invitees, assignees, subtenants, contractors, or agents, or (iii) with respect to any portion of the Premises which, immediately prior to the event which would otherwise give rise to such Untenantability, was used for storage and
which continues to be suitable for use for storage purposes, unless space which is located on the same floor and is adjacent to such portion of the Premises is also included in the Premises and is Untenantable. If the Untenantability of a portion of
the Premises results in Tenant not being able to use a larger portion of the Premises, or the entire Premises, for the conduct of its business therein, then such larger portion or the entire Premises, as the case may be, shall be deemed to be
“Untenantable.” 
 (iv) The provisions of Paragraph 24(B)(i) and (ii) shall not be applicable to any
Untenantability by reason of damage by fire or other casualty or condemnation (and the same shall be governed by the provisions of Articles 10 and 12 hereof, respectively). 
 (C) Offset Rights. Tenant shall have the setoff rights provided for in Section 16 of the Workletter or in Article 4, and the same shall be
binding upon any purchaser or transferee under Article 25 regardless of whether the same relate to matters occurring prior to such purchase or transfer. 
 (D) Rights Cumulative. The specific remedies provided to Tenant in this Lease shall be in addition to the rights and remedies available to Tenant at law or in equity, including without limitation the right to
seek actual damages, declaratory, injunctive or other equitable relief to specifically enforce this Lease. 
 ARTICLE 25. 

Conveyance by Landlord; Liability of Landlord 
 (A) Conveyance by Landlord. In the event of a sale or transfer of the Property by the Landlord hereunder (and nothing herein shall be construed to restrict or prevent such sale or transfer), (i) the
purchaser or transferee shall thereupon be and become the Landlord hereunder and shall be deemed to have fully assumed and be liable for all obligations of this Lease required to be performed by the Landlord hereunder whether relating to a period or
otherwise accruing before or after such sale or transfer (and the term “Landlord” shall be deemed to refer to such purchaser or transferee), and Tenant shall attorn to such purchaser or transferee, and (ii) the seller or
transferor shall be discharged and released from, and shall not be liable for, all obligations of this lease required to be performed by the landlord hereunder whether relating to a period or otherwise accruing before or after such sale or transfer.

  

 94 

 (B) Liability of Landlord. It is expressly understood and agreed by Tenant that none of
Landlord’s covenants, undertakings or agreements are made or intended as personal covenants, undertakings or agreements by Landlord, and any liability of Landlord for damages or breach or nonperformance by Landlord or otherwise arising under or
in connection with this Lease or the relationship of Landlord and Tenant hereunder, shall be collectible only out of Landlord’s interest in the Property (or if Landlord is the beneficiary of a land trust, Landlord’s right, title and
interest in such land trust), in each case as the same may then be encumbered (so long as any loan is to a lender that is not an Affiliate of Landlord), and no personal liability is assumed by, nor at any time may be asserted against, Landlord, its
members or its other owners, direct or remote, all such liability, if any, being expressly waived and released by Tenant. The limitations of liability of Landlord contained in this Article shall apply equally to and inure to the benefit of the
Landlord Protected Parties (as defined in Paragraph 11(b) above). Tenant further expressly understands and agrees that if any instrument involving the Building is executed by Landlord’s agent (“Landlord’s Agent”)
on behalf of Landlord, then Landlord’s Agent executes such instrument, not in its own right but solely as Landlord’s Agent and that nothing in this Lease shall be construed as creating any liability whatsoever against such Landlord’s
Agent, its owners, direct and remote, and their respective directors, officers or employees and in particular, without limiting the generality of the foregoing, there shall be no liability of Landlord’s Agent to pay any indebtedness or sum
accruing thereunder, or to perform any covenant or agreement whether expressed or implied therein contained, it being agreed that Landlord shall have sole responsibility therefor. 
 ARTICLE 26. 
 Waiver; Indemnification 
 (A) Tenant Waiver. To the extent permitted by Law, Tenant waives and releases the Landlord Protected Parties and Landlord’s contractors (but
not, with respect to claims arising out of any act or omission prior to the Rent Commencement Date, Landlord’s Contractors) from all claims for damage to property sustained by Tenant relating to 
 (i) directly or indirectly, any act or omission of any Landlord Protected Parties and/or Landlord’s contractors; 
 (ii) the Building or Premises or any part of either or any equipment or appurtenance becoming out of repair; or 
 (iii) any accident in or about the Building or Premises; or 
 (iv) directly or indirectly, any act or omission of any tenant or occupant of the Building or of any other person. 
 (B) Landlord Waiver. To the extent permitted by Law, Landlord waives and releases the Tenant Protected Parties and Tenant’s contractors (but
not, with respect to claims arising out of any act or omission prior to the Rent Commencement Date, Tenant’s Contractors) from all claims for damage to property sustained by Landlord relating to 
 (i) directly or indirectly, any act or omission of any Tenant Protected Parties and/or Tenant’s contractors; 
  

 95 

 (ii) the Building or Premises or any part of either or any equipment or appurtenance
becoming out of repair; or 
 (iii) any accident in or about the Building or Premises; or 
 (iv) directly or indirectly, any act or omission of any tenant or occupant of the Building or of any other person. 
 (C) The foregoing Paragraphs (A) and (B) shall apply especially, but not exclusively, to damage caused by the flooding of basements or other
subsurface areas, refrigerators, sprinkling devices, air-conditioning apparatus, water, snow, frost, steam, excessive heat or cold, falling plaster, broken glass, sewage, gas, odors or noise, or the bursting or leaking of pipes or plumbing fixtures,
and shall apply equally whether the damage results from the act or omission of Landlord, Tenant, other tenants of the Building or of any other person, or whether the damage is caused by or resulted from any thing or circumstance above mentioned or
referred to, or any other thing or circumstance, whether of a like or of a wholly different nature. 
 (D) Tenant’s Property. All
property situated in the Building or the Premises and belonging to Tenant, its agents, contractors, employees, or invitees or any occupant of the Premises, shall be situated there at the risk of Tenant or such other person only, and Landlord shall
not be liable for damage, theft, misappropriation, or loss of that property. 
 (E) Landlord’s Property. All property situated in
the Building or the Premises and belonging to Landlord, its agents, contractors, employees, or invitees or any occupant of the Building, shall be situated thereat the risk of Landlord or such other person only, and Tenant shall not be liable for
damage, theft, misappropriation or loss of that property. 
 (F) Tenant Indemnity. To the extent permitted by Law and not covered by
insurance, Tenant shall protect, defend, indemnify and hold harmless the Landlord Protected Parties from and against any and all claims asserted against any Landlord Protected Parties (including all liabilities, damages, judgments, orders, decrees,
actions, proceedings, fines, penalties, costs and expenses, including without limitation, court costs and reasonable attorneys’ fees arising out of any such claim) for loss of life or damage or injury to person, property or business to the
extent caused by or arising out of any violation of this Lease by, or other act or omission of, Tenant or of any other occupant of the Premises, or any of their respective agents, employees or contractors. Tenant’s obligations and liabilities
pursuant to this Paragraph 26(F) shall survive the expiration or earlier termination of this Lease. 
 (G) Landlord Indemnity. To
the extent permitted by Law and not covered by insurance, Landlord shall protect, defend, indemnify and hold harmless the Tenant and its agents, employees and contractors, members, shareholders, partners and invitees from and against any and all
claim asserted against any such person (including all liabilities, damages, judgments, orders, decrees, actions, proceedings, fines, penalties, costs and expenses, including without limitation, court costs and reasonable attorneys’ fees arising
out of any such claim) for loss of life or damage or injury to person, property or business to the extent caused by or arising out of any violation of this Lease by, or other act or omission of, Landlord or any Landlord Protected Parties or any of
their respective agents, employees or contractors. Landlord’s obligations and liabilities pursuant to this Paragraph 26(G) shall survive the expiration or earlier termination of this Lease. 
  

 96 

 (H) Relationship to Article 4. Nothing in this Article 26 shall be deemed to limit any of the
rights and obligations of Landlord and Tenant under Article 4, including any rights of Tenant under Article 4 to recover any losses, costs or damages thereunder, or any right of Landlord under Article 4 to receive an assignment of any insurance
claims or insurance proceeds. 
 ARTICLE 27. 
 Safety and Security Devices, Services and Programs 
 The parties acknowledge that safety and
security devices, services and programs provided by Landlord, while intended to deter crime and ensure safety, may not in given instances prevent theft or other criminal acts, or ensure safety of persons or property. The risk that any safety or
security device, service or program may not be effective, or may malfunction, or be circumvented by a criminal (or malefactor), is assumed by Tenant with respect to Tenant’s property and interests, and Tenant shall obtain insurance coverage to
the extent Tenant desires protection against such criminal acts and other losses, as further described in Article 11. Tenant agrees to cooperate in any reasonable safety or security program developed by Landlord and approved by Tenant, which
approval will not be unreasonably withheld, or required by Law at Landlord’s expense (subject to inclusion in Operating Expenses to the extent permitted by Article 3 above), so long as such safety or security program is applied on a
nondiscriminatory basis to all tenants of the Building. 
 ARTICLE 28. 
 Communications and Computer Lines 
 (A) Installation of Lines by
Tenant. Tenant may install, maintain, replace, remove (subject to Article 13 hereof) or use communications and/or computer conduit, cabling and wiring (collectively, the “Lines”) at the Property serving the Premises,
provided: 
 (i) such Lines are located solely within Landlord’s Telecommunications Infrastructure or the Premises,

 (ii) any such installation, maintenance, replacement and removal shall be subject to the applicable provisions of
Article 8, and shall not materially interfere with the use of any then existing Lines at the Property, and 
 (iii) if
any Lines installed by Tenant require shielding in order to prevent such Lines from causing electromagnetic interference to any Lines installed by Landlord or any other person, Tenant shall install such shielding as shall be necessary to eliminate
such interference. 
  

 97 

 Tenant shall remove any Lines installed by it which violate this Paragraph 28(A) or which are at any time in
violation of any Laws or represent a dangerous or potentially dangerous condition, within thirty (30) days after written demand from Landlord. 
 (B) Landlord Supervision of Lines in Landlord’s Telecommunication Infrastructure. Landlord may reasonably direct, monitor and/or supervise the installation, maintenance, replacement and removal of, Lines in the Landlord’s
Telecommunication Infrastructure (but Landlord shall have no right to monitor or control the information transmitted through such Lines). Such right shall not be in limitation of other rights that may be available to Landlord by Law or otherwise.

 (C) Avoidance of Interference. Landlord shall not, and shall not suffer or permit any person to, install electrical risers or other
equipment in such proximity to Landlord’s Telecommunications Infrastructure as results in electromagnetic interference with any of Tenant’s Lines therein. If any such electromagnetic interference shall arise, Landlord shall install such
shielding as shall be necessary to eliminate it. 
 (D) Liability. Except to the extent arising from the negligence or intentional
acts of Landlord or Landlord’s agents or employees, Landlord shall have no liability for damages arising from, and Landlord does not warrant that the Tenant’s use of any Lines will be free from, the following (collectively called
“Line Problems”): 
 (i) any eavesdropping or wire-tapping by unauthorized parties, 
 (ii) any failure of any Lines to satisfy Tenant’s requirements, or 
 (iii) any shortages, failures, variations, interruptions, disconnections, loss or damage caused 
  

	 	(1)	by any act, omission or failure by any service provider, 

  

	 	(2)	by the installation, maintenance, replacement, use or removal of Lines by or for other tenants or occupants at the Property, 

  

	 	(3)	by any failure of the environmental conditions or the power supply for the Property to conform to any requirements for the Lines or any associated equipment, or

  

	 	(4)	by any other problems associated with any Lines by any other cause. 

 Under no circumstances shall any Line Problems be deemed an actual or constructive eviction of Tenant, render Landlord liable to Tenant for abatement of Rent, or relieve Tenant from performance of Tenant’s obligations under this Lease.
Landlord in no event shall be liable for damages by reason of loss of profits, business interruption or other consequential damage arising from any Line Problems.

quantities of Landlord’s Hazardous Materials customarily used in the construction, operating and maintenance of office buildings may be Handled at the Property.

Tenant’s obligations under this Lease or create any liability of Landlord to Tenant, provided, however, that Landlord shall not cover or brick up any windows of the Premises. 
 ARTICLE 34.

not affect, impair or invalidate any other terms or provisions hereof, or its enforceability with respect to any other person or circumstance, the parties hereto agreeing that they would have entered into the remaining portion of this Lease
notwithstanding the omission of the portion or portions adjudged invalid, void, illegal, or unenforceable with respect to such person or circumstance.

or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the First Expansion Premises pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or

 105 

 (iv) Landlord may lease the First Expansion Premises, or portions thereof, from time to
time to third parties so long as such space is scheduled to be available to be leased to Tenant pursuant to Tenant’s First Expansion Option. So long as Landlord has not granted any person rights which conflict with Tenant’s First Expansion
Option, Landlord shall have no liability to Tenant, and Landlord shall not be deemed to be in default under this Lease, if it is unable to deliver the First Expansion Premises to Tenant on the First Expansion Option Scheduled Delivery Date due
solely to the failure of any tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver possession of the Expansion Premises in the condition required by Paragraph 35(B)(iii) by the date

assigned this Lease (other than pursuant to Paragraph 21(C)), (ii) Tenant shall not have subleased more than 25% of the Premises for all or substantially all of the remaining Term (excluding subleases pursuant to Paragraph 21(C)), and

date, Tenant shall be deemed to have waived its Second Expansion Option. 
 (iii) If Tenant timely exercises the Second
Expansion Option, then (i) on the Second Expansion Option Scheduled Delivery Date, Landlord shall deliver the Second Expansion Premises to Tenant with all Base Building Work therein complete and otherwise in “as-is” condition, and
(ii) the Second Expansion Premises shall be included in the Premises upon the same terms, covenants and conditions as are applicable to the Premises, except to the extent, if any, otherwise provided below: 
  

	 	(1)	the term of the letting of the Second Expansion Premises shall expire on the Initial Expiration Date, subject to extension of the Term pursuant to Paragraphs 35(F) and 35(G);

  

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses, with respect to the Second Expansion Premises, shall commence to be payable on the date (the “Second
Expansion Option Rent Commencement Date”) which is the earlier of: 

  

	 	(a)	the date which is one hundred twenty (120) days after the later of (x) the date on which Landlord actually tenders possession of the Second Expansion Premises to Tenant in
the condition required by this Paragraph 35(C)(iii), and (y) the Second Expansion Option Scheduled Delivery Date, and 

  

	 	(b)	the date Tenant commences to conduct ordinary business in the Second Expansion Premises, 

 provided, however, that the Second Expansion Option Rent Commencement Date shall be determined separately with respect to any portion of the Second Expansion Premises that has been previously leased to Tenant for a
term expiring immediately prior to the Second Expansion Option Scheduled Delivery Date and, with respect to such portion, the aforesaid period of 120 days shall be disregarded. 
  

	 	(3)	The amount of Net Rent per square foot of Rentable Area with respect to the Second Expansion Premises shall be equal to that applicable to the Mid-Rise Premises, as such Net Rent

Workletter; provided, however, that Tenant shall have the right to apply all or any portion of the Expansion Allowance as a credit against the Rent hereunder. 

 Following exercise by Tenant of the Second Expansion Option, and within thirty (30) days following written request by either Landlord
or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the Second Expansion Premises pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or
refusal of either party to do so, however, shall not affect the validity of the leasing of the Second Expansion Premises. 
 (iv) Landlord may lease the Second Expansion Premises, or portions thereof, from time to time to third parties so long as such space is scheduled to be available to be leased to Tenant pursuant to Tenant’s Second Expansion Option. So
long as Landlord has not granted any person rights which conflict with Tenant’s Second Expansion Option, Landlord shall have no liability to Tenant, and Landlord shall not be deemed to be in default under this Lease, if it is unable to deliver
the Second Expansion Premises to Tenant on the Second Expansion Option Scheduled Delivery Date due solely to the failure of any tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver
possession of the Second Expansion Premises in the condition required by Paragraph 35(C)(iii) by the date which is the 90th day after the Second Expansion Option Scheduled Delivery Date (as such date is extended by Unavoidable Delays), Tenant
shall have the option either, at it elects (a) by notice to Landlord given at any time prior to the delivery to Tenant of the Second Expansion Premises in the condition required by Paragraph 35(C)(iii), to rescind its previous exercise of
the Second Expansion Option, in which event Landlord shall have no liability to Tenant on account of such failure timely to deliver (except that Landlord shall not be released from such liability if it shall have granted any person rights which
conflict with Tenant’s Second Expansion Option) and shall have no further obligation to deliver the Second Expansion Premises, or (b) to lease from Landlord on a temporary basis and at the same rent other space in the Building, to the
extent available, comparable in size to the Second Expansion Premises. Landlord will use commercially reasonable efforts to regain possession of the Second Expansion Premises as promptly as reasonably possible, including the prosecution of
litigation against any occupant of such space. 
  

 108 

 (D) Third Expansion Option. If (i) Tenant shall not have assigned this Lease (other than
pursuant to Paragraph 21(C)), (ii) Tenant shall not have subleased more than 25% of the Premises for all or substantially all of the remaining Term (excluding subleases pursuant to Paragraph 21(C)), and (iii) this Lease shall
then be in full force and effect, then Tenant shall have the one-time option (the “Third Expansion Option”) to expand the Premises to include the Third Expansion Premises upon the following terms and conditions: 
 (i) The term “Third Expansion Option Scheduled Delivery Date” shall mean the date designated by Landlord, by delivery of
written notice to Tenant no later than the 30th day following Landlord’s receipt of the Third Expansion Notice, as the date on which Landlord intends to deliver the Third Expansion Premises to Tenant, which date shall be any date no earlier

 (ii) Tenant shall exercise the Third Expansion Option, if at all, by delivery to Landlord of a written notice of exercise
(the “Third Expansion Notice”) on or before the 540th day preceding the 10th anniversary of the Mid-Rise Rent Commencement Date. If Tenant fails to deliver the Third Expansion Notice by such date, Tenant shall be deemed to have

Expansion Option Scheduled Delivery Date, Landlord shall deliver the Third Expansion Premises to Tenant with all Base Building Work therein complete and otherwise in “as-is” condition, and (ii) the Third Expansion Premises shall be
included in the Premises upon the same terms, covenants and conditions as are applicable to the Premises, except to the extent, if any, otherwise provided below: 
  

	 	(1)	the term of the letting of the Third Expansion Premises shall expire on the Initial Expiration Date, subject to extension of the Term pursuant to Paragraphs 35(F) and 35(G);

  

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses, with respect to the Third Expansion Premises, shall commence to be payable on the date (the “Third
Expansion Option Rent Commencement Date”) which is the earlier of: 

  

	 	(a)	the date which is one hundred twenty (120) days after the later of (x) the date on which Landlord actually tenders possession of the Third Expansion Premises to Tenant in
the condition required by this Paragraph 35(D)(iii), and (y) the Third Expansion Option Scheduled Delivery Date, and 

  

	 	(b)	the date Tenant commences to conduct ordinary business in the Third Expansion Premises, 

 provided, however, that the Third Expansion Option Rent Commencement Date shall be determined separately with respect to any portion of the Third Expansion Premises that has been previously leased to Tenant for a term
expiring immediately prior to the Third Expansion Option Scheduled Delivery Date and, with respect to such portion, the aforesaid period of 120 days shall be disregarded. 
  

 109 

	 	(3)	The amount of Net Rent per square foot of Rentable Area with respect to the Third Expansion Premises shall be equal to that applicable to the Mid-Rise Premises, as such Net Rent
increases from time to time as set forth in Exhibit B-1. 

  

	 	(4)	The Rentable Area of the Premises shall be increased by the Rentable Area of the Third Expansion Premises; 

  

	 	(5)	Tenant’s Pro Rata Share shall be increased to reflect the Rentable Area of the Third Expansion Premises, effective as of the Third Expansion Option Rent Commencement Date; and

  

	 	(6)	Landlord shall pay to Tenant the Expansion Allowance. The Expansion Allowance shall be used and disbursed in accordance with the provisions and procedures set forth in the
Workletter; provided, however, that Tenant shall have the right to apply all or any portion of the Expansion Allowance as a credit against the Rent hereunder. 

 Following exercise by Tenant of the Third Expansion Option, and within thirty (30) days following written request by either Landlord
or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the Third Expansion Premises pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or
refusal of either party to do so, however, shall not affect the validity of the leasing of the Third Expansion Premises. 
 (iv) Landlord may lease the Third Expansion Premises, or portions thereof, from time to time to third parties so long as such space is scheduled to be available to be leased to Tenant pursuant to Tenant’s Third Expansion Option. So
long as Landlord has not granted any person rights which conflict with Tenant’s Third Expansion Option, Landlord shall have no liability to Tenant, and Landlord shall not be deemed to be in default under this Lease, if it is unable to deliver
the Third Expansion Premises to Tenant on the Third Expansion Option Scheduled Delivery Date due solely to the failure of any tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver
possession of the Expansion Premises in the condition required by Paragraph 35(D)(iii) by the date which is the 90th day after the Third Expansion Option Scheduled Delivery Date (as such date is extended by Unavoidable Delays), Tenant shall
have the option either, at it elects (a) by notice to Landlord given at any time prior to the delivery to Tenant of the Third Expansion Premises in the condition required by Paragraph 35(D)(iii), to rescind its previous exercise of the
Third Expansion Option, in which event Landlord shall have no liability to Tenant on account of such failure timely to deliver (except that Landlord shall not be released from such liability if it shall have granted any person rights which conflict
with Tenant’s Third Expansion Option) and shall have no 

  

 110 

 
further obligation to deliver the Third Expansion Premises, or (b) to lease from Landlord on a temporary basis and at the same rent other space in the
Building, to the extent available, comparable in size to the Third Expansion Premises. Landlord will use commercially reasonable efforts to regain possession of the Third Expansion Premises as promptly as reasonably possible, including the
prosecution of litigation against any occupant of such space. 
 (E) Tenant’s Right of First Offer. 
 (i) If (i) Tenant shall not have assigned this Lease (other than pursuant to Paragraph 21(C)), (ii) Tenant shall not have
subleased more than 25% of the Premises for all or substantially all of the remaining term (excluding subleases pursuant to Paragraph 21(C)), (iii) neither Tenant’s First Renewal Option nor Tenant’s Third Renewal Option shall
have lapsed without exercise, and (iv) neither this Lease nor Tenant’s right of possession of the Premises shall have been terminated and this Lease shall then be in full force and effect, then Landlord shall not lease any space on any of
the 3rd through 27th floors of the Building (including by way of renewal, extension or expansion) to any person other than pursuant to: 
  

	 	(1)	(a) the initial lease of such space; and (b) except with respect to space located on an Expansion Floor, any renewal or extension of the initial lease of such space
effected pursuant to the exercise of a renewal or extension right or option provided for in such initial lease as originally entered into (it being understood that if such space is located on an Expansion Floor, then any such renewal or extension
right or option shall be subordinate to Tenant’s rights under this Paragraph 35(E)); 

  

	 	(2)	(a) any lease of such space effected pursuant to Paragraph 35(E)(vi); and (b) except with respect to space located on an Expansion Floor, any renewal or extension of
such lease of such space effected pursuant to the exercise of a renewal or extension right or option provided for in such lease as originally entered into (it being understood that if such space is located on an Expansion Floor, then any such
renewal or extension right or option shall be subordinate to Tenant’s rights under this Paragraph 35(E)); 

  

	 	(3)	any Permitted Expansion of any lease entered into pursuant to subparagraphs 1 or 2 above; 

  

	 	(4)	 except with respect to space located on an Expansion Floor, any lease of such space effected pursuant to the exercise by the tenant thereunder of any expansion
right or option (which phrase, as used in this Paragraph 35(E), shall include any firm option, right of refusal or right of offer) set forth in the Goldman Sachs Lease as originally entered 

  

 111 

	 	 
into or in the Mayer Brown Lease as originally entered into (“Permitted Superior Expansion Rights”) (it being understood that (1) if
such space is located on an Expansion Floor, then any such expansion right or option shall be subordinate to Tenant’s rights under this Paragraph 35(E) and (2) except for the Permitted Superior Expansion Rights and the Permitted
Expansions referred to in Paragraph 35(E)(i)(3) above, all expansion rights and options now or hereafter granted to any person shall be subordinate to Tenant’s rights under this Paragraph 35(E)); 

  

	 	(5)	(a) any lease for a term commencing after the 22nd anniversary of the Rent Commencement Date; or (b) any lease entered into after the lapse without exercise of the First
Renewal Option or after the lapse with exercise of the Second Renewal Option (or in either case, if a Renewal Option shall have been exercised, then after Tenant elects to rescind such exercise as provided in Paragraphs 35(F) and 35(G));

  

	 	(6)	any lease of the Fitness Center or the Cafeteria to any operator, licensee or concessionaire thereof; 

  

	 	(7)	any lease on the ground floor lobby level of the Building; and 

  

	 	(8)	any lease of premises to Tenant. 

 Landlord represents and
warrants to Tenant that attached hereto as Exhibit PSER is a true and complete copy of provisions of the Mayer Brown Lease and the Goldman Sachs Lease containing the Permitted Superior Expansion Rights, excluding the portion of such
provisions setting forth the rent payable thereunder. 
 The term “Permitted Expansion” means the leasing by any tenant of
the Building of additional space in the Building, pursuant to the exercise by such tenant of any expansion right or option contained in such tenant’s lease as originally entered into, provided such additional space (i) is contiguous to,
and on the same floor as, the premises demised by such lease as originally entered into, and (ii) is no larger than 25% of the premises demised by such lease as originally entered into. 
 (ii) Landlord may, from time to time, give one or more Offer Notices. The term “Offer Notice” shall mean a notice: 
  

	 	(1)	referring to this Paragraph 35(E); 

  

	 	(2)	describing the premises to which it relates (the “Offer Space”) and, if the Offer Space includes a portion less than all of the rentable area of any floor,
including a floor plan of such floor with such portion hatched; 

  

 112 

	 	(3)	setting forth the date (which shall be a single date and shall be no earlier than 30 days after and no later than (a) 547 days after the date of such Offer Notice, if the Offer
Space includes three or fewer full floors of the Building, or (b) otherwise, 912 days after the date of such Offer Notice) on which, if Tenant exercises its right pursuant to this Paragraph 35(E) to lease such Offer Space, Landlord
reasonably believes, on the basis of written agreements then in effect, that it will be able to deliver to Tenant vacant possession thereof (the “Scheduled Offer Space Delivery Date”); 

  

	 	(4)	setting forth Landlord’s good faith opinion of the Fair Market Rental Value of the Offer Space; and 

  

	 	(5)	if all or any portion of such Offer Space is not located on a Senior ROFO Floor and is subject to a Permitted Superior Expansion Right, so stating and identifying the lease
containing such Permitted Superior Expansion Right [(which shall be either the Goldman Sachs Lease or the Mayer Brown Lease)], and setting forth (i) the portion of such Offer Space subject thereto (including, if less than all of such Offer
Space on a floor, a floor plan showing the same), and (ii) the date on which Landlord is required, if such Permitted Superior Expansion Right is exercised, to deliver such portion of such Offer Space to the holder of such Superior Expansion
Right (the “Permitted Superior Expansion Right Delivery Date”). 

 Each Offer Notice shall constitute a
representation by Landlord that all leases covering any of such Offer Space have expired or been terminated or, pursuant to the terms thereof or other written agreements then in effect, will expire or terminate with respect to such Offer Space on or
prior to the Scheduled Offer Space Delivery Date set forth in such Offer Notice. 
 If pursuant to the provisions of any other lease (a
“Recapture Provision”) Landlord shall become entitled to recapture any space in the Building in connection with a proposed assignment or sublease (a “Recapture Space”), Landlord shall, within five (5) Business
Days of its receipt of the notice from the other tenant entitling Landlord to recapture, give to Tenant an Offer Notice with respect to such space. Such Offer Notice (a “Recapture Offer Notice”) shall, in addition to the information
required by the foregoing provisions of this Paragraph 35(E)(ii) to be included therein, set forth (a) that it relates to space which Landlord is entitled to recapture, (b) the last day on which Landlord is permitted by the terms
of the applicable lease to exercise such recapture right (the “Landlord’s Exercise Deadline Date”), (c) a schedule of the net base rent that such other tenant is obligated to pay for such Recapture Space (the
“Recapture Space Rent Schedule”), and (d) the date on which the then-committed term of such lease shall expire with respect to the Recapture Space (the “Recapture Space Expiration Date”) and be accompanied by a
copy of the provisions of such other lease establishing the Recapture Space Rent Schedule and the Recapture Space Expiration Date. No Offer Notice shall include Recapture Space and any space which is not Recapture Space. Landlord shall not waive or
amend any lease so as to eliminate any Recapture Provision. 
  

 113 

 (iii) Tenant shall have the right, by notice to Landlord given within twenty
(20) Business Days of its receipt of any Offer Notice (an “Acceptance Notice”), to lease all or any portion of the Offer Space covered by such Offer Notice; provided, however, that 
  

	 	(1)	if Tenant elects to lease and include in its Acceptance Notice any of such Offer Space on any floor of the Building, then Tenant shall be obligated to lease and include in such
Acceptance Notice all of such Offer Space on such floor of the Building; 

  

	 	(2)	if the Offer Space includes a block of two or more contiguous full floors (an “Offer Space Block”), then 

  

	 	(i)	the term “M” shall mean the number of contiguous full floors in the block, and the term “N” shall mean the number of contiguous full floors which
Tenant desires to lease and include in its Acceptance Notice, and 

  

	 	(ii)	if N is less than M, then the term “Lower N Block” shall be the block of N contiguous full floors within such Offer Space Block containing the lowest full floor
thereof (or if N is one, just such lowest full floor) and the term “Upper N Block” shall be the block of N contiguous full floors within such Offer Space Block containing the highest full floor thereof (or if N is one, just such
highest full floor), and 

  

	 	(F)	if only one of the N Blocks is contiguous to the Premises, Tenant shall lease and include in its Acceptance Notice, such N Block, 

  

	 	(G)	if both of such N Blocks are contiguous to the Premises, Tenant shall lease and include in its Acceptance Notice, either of such N Blocks (as Tenant shall elect), and

  

	 	(H)	if neither N Block is contiguous to the Premises, Tenant shall lease and include in its Acceptance Notice either of such N Blocks (as Tenant shall elect) and Landlord shall have the
right in any case under this clause (C), by notice to Landlord given within thirty (30) days of such Acceptance Notice, to substitute the other N Block therefor, 

  

 114 

	 	(1)	in case of any Recapture Offer Notice, the Acceptance Notice (herein, a “Recapture Acceptance Notice”) 

  

	 	(a)	must be given, if at all, no later than the earlier of (i) the date provided for above in this Paragraph 35(E)(iii), or (ii) the second (2nd) Business Day prior to
Landlord’s Exercise Deadline Date set forth in such Recapture Offer Notice; and 

  

	 	(b)	must include all of such Offer Space; 

  

	 	(2)	if Tenant shall give such any Acceptance Notice later than 1095 days before the Initial Term Expiration Date and Tenant shall not have theretofore given (and waived (or been deemed
to have waived) its right to rescind) the First Renewal Notice then such Acceptance Notice shall not be valid unless accompanied or preceded by a Renewal Commitment Notice for the First Renewal Period; and 

  

	 	(3)	if Tenant shall give any such Acceptance Notice later than 1095 days before the fifth anniversary of the Initial Term Expiration Date and Tenant shall not have theretofore given
(and waived (or been deemed to have waived) its right to rescind) the Second Renewal Notice then such Acceptance Notice shall not be valid unless accompanied or preceded by a Renewal Commitment Notice for the Second Renewal Period.

 The space as to which Tenant timely gives an Acceptance Notice is herein called an “Accepted Offer Space.” Tenant shall, in
its Acceptance Notice, state whether it agrees with Landlord’s estimate of the Fair Market Rental Value set forth in Landlord’s Offer Notice and, if not, Tenant shall include in its Acceptance Notice a statement of Tenant’s good faith
opinion of the Fair Market Rental Value of the Accepted Offer Space. 
 (ii) If Tenant timely gives an Acceptance Notice then
(i) on the Scheduled Offer Space Delivery Date, Landlord shall deliver the Accepted Offer Space to Tenant with all Base Building Work therein complete, ordinary wear and tear excepted, and otherwise in “as-is” condition (except that
in the case of a Recapture Acceptance, such Accepted Offer Space shall be delivered in “as-is” condition), and (ii) the Accepted Offer Space shall be included in the Premises upon the same terms, covenants and conditions as are
applicable to the Premises, except to the extent, if any, otherwise provided below: 
  

	 	(1)	the term of the letting of the Accepted Offer Premises shall expire on the Initial Term Expiration Date, and the Accepted Offer Premises shall be subject to Paragraphs 35(F) and
(G); provided, however, that 

  

	 	(a)	if prior to the giving of such Acceptance Notice, the First Renewal Notice shall have been given then the term of the letting of such Accepted Offer Space shall expire on the First
Renewal Term Expiration Date, and the Accepted Offer Space shall be subject to Paragraph 35(G), provided, however, that if such First Renewal Notice shall have been or shall thereafter be rescinded pursuant to Paragraph 35(F)(iii) this clause
(a) shall be disregarded; 

  

 115 

	 	(b)	if prior to the giving of such Acceptance Notice, the Second Renewal Notice shall have been given then the term of the letting of such Accepted Offer Space shall expire on the
Second Renewal Term Expiration Date, provided, however, that if such Second Renewal Notice shall have been or shall thereafter be rescinded pursuant to Paragraph 35(G)(iii) this clause (b) shall be disregarded; 

  

	 	(c)	if such Accepted Offer Space or any portion thereof shall be subject to a Permitted Superior Expansion Right (and Landlord shall have so stated in its Offer Notice), then the term
of the letting with respect to such Accepted Offer Space or portion thereof shall expire on the earlier of (a) the day provided by the foregoing provisions of this Paragraph 35(E)(iv)(1), and (b) the day preceding the Landlord
Permitted Superior Expansion Right Delivery Date; 

  

	 	(d)	if such Accepted Offer Space or any portion thereof shall be located on a floor(s) on which Expansion Premises are located and, at the time of Tenant’s giving of the Acceptance
Notice with respect thereto, the Expansion Option applicable to such Expansion Premises shall not have lapsed without exercise, then the term of the letting with respect to such Accepted Offer Space or portion thereof shall expire on the earlier of
(a) the date provided by the foregoing provisions of this Paragraph 35(E)(iv)(1), and (b) the day preceding the applicable Expansion Option Scheduled Delivery Date; and, 

  

	 	(iii)	if Tenant timely exercises the applicable Expansion Option, then on the earlier of (a) the date provided by the foregoing provisions of this Paragraph 35(E)(iv)(1), and
(b) the day preceding the applicable Expansion Option Scheduled Delivery Date, and 

  

 116 

	 	(iv)	otherwise, on the date otherwise provided by the foregoing provisions of this Paragraph 35(E)(iv)(1); and 

  

	 	(a)	if Landlord shall have given a Recapture Offer Notice setting forth a Recapture Space Expiration Date that is later than the date on which (in the absence of this clause (e)) the
term of the letting of such Accepted Offer Premises would expire pursuant to the foregoing provisions of this Section 35(E)(iv)(1), (any such Accepted Offer Premises being herein referred to as “Long Term Recapture Space”), the
term of the letting of the Accepted Offer Space shall expire on such Recapture Space Expiration Date so set forth (the date of such expiration being herein referred to as the “Long Term Recapture Space Expiration Date”).

  

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses with respect to such Accepted Offer Space shall commence to be payable on the earlier of (such earlier date
being herein called the “Offer Space Rent Commencement Date”): 

  

	 	(a)	the date which is one hundred twenty (120) days after the later of (i) the date on which Landlord actually tenders possession of the Accepted Offer Space to Tenant in the
condition required by this Paragraph 35(E)(iv)), and (ii) the Scheduled Offer Space Delivery Date; or 

  

	 	(b)	the date Tenant commences to conduct ordinary business in the Offer Space; 

  

	 	(3)	The amount of Net Rent with respect to the Offer Space shall be equal to: 

  

	 	(a)	except in a case of a Recapture Acceptance Notice, (x) if Tenant in its Acceptance Notice shall have agreed with Landlord’s estimate of the Fair Market Rental Value set
forth in the Offer Notice, such Fair Market Rental Value so set forth, (y) otherwise, the Fair Market Rental Value of the Accepted Offer Space as determined pursuant to Paragraph 35(E)(viii); and 

  

	 	(b)	in the case of a Recapture Acceptance Notice, then the greater of (x) the Fair Market Rental Value of the Accepted Offer Space, determined either by Tenant having agreed in its
Recapture Acceptance Notice with Landlord’s estimate of the Fair Market Rental Value set forth in the Offer Notice or determined pursuant to Paragraph 35(E)(viii), and (y) that provided by the Recapture Space Rent Schedule.

  

 117 

	 	(4)	The Rentable Area of the Premises shall be increased by the Rentable Area of the Offer Space; and 

  

	 	(5)	Tenant’s Pro Rata Share shall be increased to reflect the Rentable Area of the Accepted Offer Space, effective as of the Accepted Offer Space Rent Commencement Date.

 Following the giving by Tenant of an Acceptance Notice and the determination of the Net Rent with respect to the Accepted
Offer Space covered thereby, and within thirty (30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the Accepted Offer
Space pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or refusal of either party to do so, however, shall not affect the validity of the leasing of the Accepted Offer Space. 
 (v) So long as, when Tenant gives an Offer Notice, it is entitled, on the basis of written agreements then in effect, to possession of the
Offer Space no later than the Scheduled Offer Space Delivery Date set forth therein, Landlord shall not be deemed to be in default under this Lease if it is unable to deliver any Accepted Offer Space on such Scheduled Offer Space Delivery Date due
solely to the failure of such tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver possession of any Accepted Offer Space in the condition required by Paragraph 35(E)(iv) by the 90th
day after the Scheduled Offer Space Delivery Date, Tenant shall have the option, by written notice to Landlord given at any time prior to the delivery to Tenant of the Accepted Offer Space in the condition required by Paragraph 35(E)(iv), to
rescind its Acceptance Notice, in which event Landlord shall have no liability to Tenant on account of such failure timely to deliver (except that Landlord shall not be released from such liability if the representation set forth in the penultimate
paragraph of Paragraph 35(E)(ii) shall have been breached). Landlord will use commercially reasonable efforts to regain possession of such Accepted Offer Space as promptly as reasonably possible, including the prosecution of
litigation against any occupant of such space. 
 (vi) (1) If in response to any Offer Notice Tenant shall fail timely to
deliver an Acceptance Notice (or the same shall be rescinded pursuant to Paragraph 35(E)(v)) then Landlord shall be permitted to lease all or any portion of the Offer Space covered by such Offer Notice to any person or persons for delivery no
earlier than the Scheduled Offer Space Delivery Date set forth in such Offer Notice (and otherwise on such terms as Landlord shall determine in its discretion (subject to Tenant’s rights under this Paragraph 35(E) with respect to renewals,
extensions and expansions and Tenant’s rights under Paragraphs 35(B), (C) and (D) if applicable)); provided, however, that immediately subsequent to the original entering into of any such lease the space covered thereby shall again
become subject to this Article such that Landlord shall not (except as permitted by the other provisions of Paragraph 35(E)(i), if and to the extent applicable) subsequently lease such space except pursuant to this Paragraph 35(E)(vi)
based upon a subsequent Offer Notice given to Tenant with respect thereto. 
  

 118 

	 	(1)	If in response to any Offer Notice Tenant shall timely deliver an Acceptance Notice with respect to less than all of the Offer Space covered by such Offer Notice then Landlord shall
be permitted to lease all or any portion of the balance of such Offer Space converted by such Offer Notice to any person or persons for delivery no earlier than the Scheduled Offer Space Delivery Date set forth in such Offer Notice (and otherwise on
such terms as Landlord shall determine in its discretion (subject to Tenant’s rights under this Article 35(E) with respect to renewals, extensions and expansions and Tenant’s rights under Paragraphs 35(B), (C) and (D) if
applicable)); provided, however, that immediately subsequent to the original entering into of any such lease the space covered thereby shall again become subject to this Article such that Landlord shall not (except as permitted by the other
provisions of Paragraph 35(E)(i), if and to the extent applicable) subsequently lease such space except pursuant to this Paragraph 35(E)(vi) based upon a subsequent Offer Notice given to Tenant with respect thereto.

 (vii) The term “Fair Market Rental Value” of any Accepted Offer Space shall mean the fair
market amount of net base rent, expressed in dollars and cents per square foot of Rentable Area of the Accepted Offer Space (i.e. exclusive of Taxes, Net Shared Facilities Costs and Operating Expenses) (fixed or with specified percentage increases
at specified intervals), under a lease for a term commencing on the applicable Scheduled Offer Space Delivery Date and ending on a date which is the later to occur of (a) the tenth (10) anniversary of the Scheduled Offer Space Delivery
Date, and (b) the date provided for in Paragraph 35(E)(iv) for the expiration of the term of the letting of such Accepted Offer Space, and otherwise on the terms and conditions of this Lease to be applicable to such Accepted Offer Space,
determined as if the Accepted Offer Space were then available in the then rental market and assuming 
  

	 	(1)	that Landlord has a reasonable time to locate a tenant; and 

  

	 	(2)	that neither Landlord not such tenant is under any compulsion to rent. 

 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers to or considers any transaction in which the landlord provided free rent or a tenant improvement allowance or
any work to prepare the premises for the tenant’s occupancy or any lease takeover or any other concession (all of the foregoing being herein called a “Leasing Concession”), then in so referring to or considering such
transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction shall be adjusted downward by subtracting the product of 12 multiplied by the amount which, if taken monthly over the term of such
transaction, would have a net present value (using such interest rate as the arbitrator or other person applying this paragraph believes to be appropriate considering market practices) as of the commencement of such transaction equal to the amount
of such Leasing Concession. 
  

 119 

 (viii) If (a) in Tenant’s Acceptance Notice Tenant shall have stated that it
does not agree with Landlord’s estimate of the Fair Market Rental Value set forth in Landlord’s Offer Notice and shall have included therein a statement of Tenant’s good faith opinion of the Fair Market Rental Value of the Accepted
Offer Space, and (b) the parties are unable to agree on the Fair Market Rental Value within thirty (30) days after the giving of Tenant’s Acceptance Notice (the “Accepted Offer Space Negotiation Period”), then
(x) Landlord and Tenant nonetheless shall be bound to the leasing of the Accepted Offer Space pursuant to this Paragraph 35(E), and (y) the Fair Market Rental Value shall be determined by arbitration pursuant to Article 36 (and
Landlord and Tenant shall be bound to the Fair Market Rental Value as so determined). 
 (I) First Renewal Option. Tenant shall have
the option to extend the Term of this Lease as to the First Renewal Premises for five (5) years commencing upon the expiration of the initial term (the “First Renewal Term”). 
 (i) The term “First Possible Renewal Premises” shall mean all of the Premises subject to this Lease at the time of the
giving of the First Renewal Notice, including any Premises as to which an Acceptance Notice shall have been given pursuant to Paragraph 35(E) even if the same shall not yet have been delivered to Tenant. The term “First Renewal
Premises” shall mean all or such portions of the First Possible Renewal Premises as shall be specified in the First Renewal Notice, except that if any portion of First Possible Renewal Premises located on a floor are included in the First
Renewal Premises, then all portions of the First Possible Renewal Premises located on such floor shall be included. 
 (ii)
The First Renewal Term shall be upon the terms and conditions contained herein, including without limitation the payment of Tenant’s Pro Rata Share of Taxes and Operating Expenses, determined on the same basis as set forth in Article 3 of
this Lease, except that (a) the Net Rent for the First Renewal Term shall be the Fair Market Rental Value of the First Renewal Premises for the First Renewal Term and (b) if the First Renewal Premises shall be less than the entire First
Possible Renewal Premises, Tenant’s Pro Rata Share shall be recalculated on the basis of the First Renewal Premises. 
 (iii) Tenant shall provide notice to Landlord (“First Renewal Notice”) of Tenant’s exercise of the First Renewal Options no later than the day 612 days prior to the Initial Term Expiration Date. On the day 567 days
prior to the Initial Term Expiration Date (or, if such day is not a Business Day, on the next Business Day), Landlord and Tenant shall, at the Building’s management office, each simultaneously submit to the other, in a sealed envelope, its
signed written good faith estimate of the Fair Market Rental Value (the “Preliminary Estimates”). Each Preliminary Estimate shall consist of only a single fixed dollar amount per square foot of Rentable Area. Tenant shall have the
right, by notice to Landlord given within 20 days of the exchange of Preliminary Estimates, to rescind the First Renewal Notice, whereupon if exercised, Tenant shall have no further rights to extend 

  

 120 

 
the Term pursuant to this Paragraph 35(F). If Tenant does not timely rescind the First Renewal Notice, Landlord and Tenant hereby agree to be conclusively
bound to the renewal of this Lease for the First Renewal Premises for the First Renewal Term at the Fair Market Rental Value determined by arbitration pursuant to Article 36. 
 (iv) If the Premises includes any Long Term Recapture Space with a Long Term Recapture Space Expiration Date during or after the Second
Renewal Term, then, such Long Term Recapture Space shall be excluded from the First Possible Renewal Premises. If the Premises include any Long Term Recapture Space with a Long Term Recapture Space Expiration Date during the First Renewal Term then
(i) such Long Term Recapture Space shall be included in the First Possible Renewal Premises and (ii) if included by Tenant in the First Renewal Premises, the renewal thus effected with respect thereto shall be only for (and the Fair Market
Rental Value provided for in this Article 35(F) shall be payable only for) the period commencing immediately after the Long Term Recapture Space Expiration Date with respect thereto and ending at the end of the First Renewal Term. This
Paragraph 35(F)(iv) shall not be construed to result in the expiration of the letting of any Long Term Recapture Space prior to the Long Term Recapture Space Expiration Date with respect thereto. 
 (v) The term “Fair Market Rental Value” of the First Renewal Premises shall mean the fair market amount of net fixed base
rent per square foot of Rentable Area of the First Renewal Premises (i.e. exclusive of Taxes and Operating Expenses) under a lease for a term equal to the First Renewal Term and otherwise on all of the terms and conditions of this Lease to be
applicable to the First Renewal Premises for the First Renewal Term, determined as if the First Renewal Premises were then available in the then rental market, and assuming 
  

	 	(1)	that Landlord has a reasonable time to locate a tenant, 

  

	 	(2)	that neither Landlord nor such tenant is under any compulsion to rent. 

 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers to or considers any transaction in which the landlord provided free rent or a tenant improvement allowance or
any work to prepare the premises for the tenant’s occupancy or any lease takeover or any other concession (all of the foregoing being herein called a “Leasing Concession”), then in so referring to or considering such
transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction shall be adjusted downward by subtracting the product of 12 multiplied by the amount which, if taken monthly over the term of such
transaction, would have a net present value (using such interest rate as the arbitrator or other person applying this paragraph believes to be appropriate considering market practices) as of the commencement of such transaction equal to the amount
of such Leasing Concession. 
 If and to the extent that any arbitrator or other person determining the Fair Market Rental
Value refers to or considers any transaction in which a method different from the Measurement Method was used in determining rentable and usable areas, then in so referring to or considering such transaction for purposes of determining Fair Market
Rental Value the net base rent provided for in such transaction shall be adjusted accordingly. 
  

 121 

 (J) Second Renewal Option. Tenant shall have the option to extend the Term of this Lease as to the
Second Renewal Premises for five (5) years commencing upon the expiration of the First Renewal Term (the “Second Renewal Term”). 
 (i) The term “Second Possible Renewal Premises” shall mean all of the Premises subject to this Lease at the time of the giving of the Second Renewal Notice, including any Premises as to which an
Acceptance Notice shall have been given pursuant to Paragraph 35(E) even if the same shall not yet have been delivered to Tenant. The term “Second Renewal Premises” shall mean all or such portions of the Second Possible Renewal
Premises as shall be specified in the Second Renewal Notice, except that if any portion of Second Possible Renewal Premises located on a floor are included in the Second Renewal Premises, then all portions of the Second Possible Renewal Premises
located on such floor shall be included. 
 (ii) The Second Renewal Term shall be upon the terms and conditions contained
herein, including without limitation the payment of Tenant’s Pro Rata Share of Taxes and Operating Expenses, determined on the same basis as set forth in Paragraph 3(C) of this Lease, except that (a) the Net Rent for the Second
Renewal Term shall be the Fair Market Rental Value of the Second Renewal Premises for the Second Renewal Term and (b) if the Second Renewal Premises shall be less than the entire Second Possible Renewal Premises, Tenant’s Pro Rata Share
shall be recalculated on the basis of the Second Renewal Premises. 
 (iii) Tenant shall provide notice to Landlord
(“Second Renewal Notice”) of Tenant’s exercise of the Second Renewal Options no later than the day 612 days prior to the First Renewal Term Expiration Date. On the day 567 days prior to the First Renewal Term Expiration Date
(or, if such day is not a Business Day, on the next Business Day), Landlord and Tenant shall, at the Building’s management office, each simultaneously submit to the other, in a sealed envelope, its signed written good faith estimate of the Fair
Market Rental Value (the “Preliminary Estimates”). Each Preliminary Estimate shall consist of only a single fixed dollar amount per square foot of Rentable Area. Tenant shall have the right, by notice to Landlord given within 20
days of the exchange of Preliminary Estimates, to rescind the Second Renewal Notice, whereupon, if exercised, Tenant shall have no further rights to extend the Term of this Lease pursuant to this Paragraph 35(G). If Tenant does not timely rescind
the Second Renewal Notice, Landlord and Tenant hereby agree to be conclusively bound to the renewal of this Lease for the Second Renewal Premises for the Second Renewal Term at the Fair Market Rental Value determined by arbitration pursuant to
Article 36. 
  

 122 

 (iv) If the Premises includes any Long Term Recapture Space with a Long Term Recapture
Space Expiration Date after the Second Renewal Term then such Long Term Recapture Space shall be excluded form the Second Possible Renewal Premises. If the Premises include any Long Term Recapture Space with a Long Term Recapture Space Expiration
Date during the Second Renewal Term then (i) such Long Term Recapture Space shall be included in the Second Possible Renewal Premises and (ii) if included by Tenant in the Second Renewal Premises, the renewal thus effected with respect
thereto shall be only for (and the Fair Market Rental Value Provided for in this Article 35(G) shall be payable only for) the period commencing immediately after the Long Term Recapture Space Expiration Date with respect thereto and ending at the
end of the Second Renewal Term. This Paragraph 35(G)(iv) shall not be construed to result in the expiration of the letting of any Long Term Recapture Space prior to the Long Term Recapture Space Expiration Date with respect thereto. 
 (v) The term “Fair Market Rental Value” of the Second Renewal Premises shall mean the fair market amount of net fixed
base rent per square foot of Rentable Area of the Second Renewal Premises (i.e. exclusive of Taxes and Operating Expenses) under a lease for a term equal to the Second Renewal Term and otherwise on all of the terms and conditions of this Lease to be
applicable to the Second Renewal Premises for the Second Renewal Term, determined as if the Second Renewal Premises were then available in the then rental market, and assuming 
  

	 	(1)	that Landlord has a reasonable time to locate a tenant, 

  

	 	(2)	that neither Landlord nor such tenant is under any compulsion to rent. 

 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers to or considers any transaction in which the landlord provided free rent or a tenant improvement allowance or
any work to prepare the premises for the tenant’s occupancy or any lease takeover or any other concession (all of the foregoing being herein called a “Leasing Concession”), then in so referring to or considering such
transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction shall be adjusted downward by subtracting the product of 12 multiplied by the amount which, if taken monthly over the term of such
transaction, would have a net present value (using such rate as the arbitrator or other person applying this paragraph believes to be appropriate considering market practices) as of the commencement of such transaction equal to the amount of such
Leasing Concession. 
 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value
refers to or considers any transaction in which a method different from the Measurement Method was used in determining rentable and usable areas, then in so referring to or considering such transaction for purposes of determining Fair Market Rental
Value the net base rent provided for in such transaction shall be adjusted accordingly. 
 (K) Renewal Options – General.

 (i) Tenant shall not be entitled to exercise a Renewal Option if on the date Tenant exercises such Renewal Option,
(a) a monetary or material non-monetary Default has occurred and is continuing, or (b) this Lease or Tenant’s right of possession has 

  

 123 

 
been terminated, or (c) this Lease is not in full force and effect. Tenant shall not be entitled to the Third Renewal Option unless Tenant shall have
exercised the Second Renewal Option, and Tenant shall not be entitled to exercise the Second Renewal Option unless Tenant shall have exercised the First Renewal Option. 
 (ii) Following exercise by Tenant of a Renewal Option and determination of the Net Rent for the respective Renewal Term, at the request of
either party hereto and within thirty (30) days after such request, Landlord and Tenant shall enter into a supplement to this Lease confirming the renewal of this Lease for such Renewal Term, the Renewal Premises, and the term of such renewal.
The failure or refusal of either party to do so, however, shall not affect the validity of the exercise of the Renewal Option. 
 (iii) The term “Renewal Term” shall mean, individually, either the First Renewal Term or the Third Renewal Term and together shall mean the First Renewal Term and the Third Renewal Term. The term “Renewal Option” shall
mean either the First Renewal Option or the Third Renewal Option. The term “Renewal Premises” shall mean either the First Renewal Premises or the Third Renewal Premises. 
 (iv) The term “First Renewal Commitment Notice” shall mean a notice referring to this Paragraph 35(H)(iv), in which Tenant
irrevocably agrees to give (and not to rescind) the First Renewal Notice and to include in the First Renewal Premises (in addition to any other premises required to be include) all Accepted Offer Space as to which Tenant gives an Acceptance Notice
together with or after the date of such First Renewal Commitment Notice. If Tenant gives a First Renewal Commitment Notice prior to its giving a First Renewal Notice, but shall fail timely to give a Renewal Notice conforming to the requirement of
this Paragraph 35(H)(iv), then Tenant shall be deemed timely to have given a First Renewal Notice setting forth as the First Renewal Premises all of the First Possible Renewal Premises. If Tenant gives a First Renewal Commitment Notice, Tenant
shall no longer have the right to rescind the First Renewal Notice and, if Tenant shall have theretofore given the First Renewal Notice, the same shall be deemed amended to include in the First Renewal Premises (in addition to any other premises
required to be included) all Accepted Offer Space as to which Tenant gives an Acceptance Notice together with or after the date of such First Renewal Commitment Notice. 
 (v) The term “Second Renewal Commitment Notice” shall mean a notice referring to this Paragraph 35(H)(v), in which Tenant
irrevocably agrees to give (and not to rescind) the Second Renewal Notice and to include in the Second Renewal Premises (in addition to any other premises required to be included) all Accepted Offer Space as to which Tenant gives an Acceptance
Notice together with or after the date of such Second Renewal Commitment Notice. If Tenant gives a Second Renewal Commitment Notice prior to its giving a Second Renewal Notice, but shall fail timely to give a Renewal Notice conforming to the
requirement of this Paragraph 35(H)(v), then Tenant shall be deemed timely to have given a Second Renewal Notice setting forth as the Second Renewal Premises all of the Second Possible Renewal Premises. If Tenant gives a Second 

  

 124 

 
Renewal Commitment Notice, Tenant shall no longer have the right to rescind the Second Renewal Notice and, if Tenant shall have theretofore given the Second
Renewal Notice, the same shall be deemed amended to include in the Second Renewal Premises (in addition to any other premises required to be included) all Accepted Offer Space as to which Tenant gives an Acceptance Notice together with or after the
ate of such Second Renewal Commitment Notice. 
 (L) Contraction Option. Tenant shall have the one-time option (the
“Contraction Option”) to eliminate the entire 46th floor of the Building (the “Contraction Space”) from the Premises by giving Landlord notice thereof on or before the fourth (4th) anniversary of the High-Rise
Rent Commencement Date. Tenant’s right to exercise the Contraction Option is subject to the following terms and conditions (as applicable): 
 (i) Tenant shall designate in such written notice the date (the “Contraction Effective Date”) on which Tenant shall surrender possession of the Contraction Space to Landlord. Such Contraction
Effective Date shall be the last day of a calendar month during the period commencing on the fifth (5th) anniversary of the High-Rise Rent Commencement Date and ending on the sixth (6th) anniversary of the High-Rise Rent Commencement Date.

 (ii) Any exercise by Tenant of the Contraction Option shall be null and void and of no force and effect if, on the date of
such exercise, (a) this Lease has been terminated, or (b) this Lease is not in full force and effect. 
 (iii) If
Tenant properly exercises the Contraction Option, then, 
  

	 	(a)	Tenant shall pay to Landlord, within thirty days following receipt of a statement from Landlord setting forth the amount of the Contraction Fee, an amount (the “Contraction
Fee”) equal to the sum of (i) the unamortized portion of the Fit-Out Allowance allocable to the Contraction Space, as same shall have been amortized on a straight line basis over the Initial Term of this Lease, plus (ii) the Net
Rent that would otherwise be due and payable by Tenant to Landlord but for Tenant’s exercise of the Contraction Option for the one year period commencing on the Contraction Effective Date, plus (iii) an amount equal to Tenant’s Pro
Rata Share of Taxes and Operating Expenses for the calendar year immediately preceding the calendar year in which the Contraction Effective Date shall occur. 

  

	 	(b)	Tenant shall surrender possession of the Contraction Space in accordance with the terms and provisions of Article 13 hereof. If Tenant fails to surrender possession of the
Contraction Space on or before the Contraction Effective Date, Tenant shall be deemed a holdover tenant in such Contraction Space, and shall be liable to Landlord for all damages resulting from such holdover after the Contraction Effective Date.
From and after the Contraction Effective Date (or such later date on which Tenant actually surrenders possession of the Contraction Space), the Net Rent and Tenant’s Pro Rata Share shall be appropriately adjusted. 

  

 125 

	 	(c)	Tenant, notwithstanding its surrender of the Contraction Space, shall remain liable for all Rent allocable to the Contraction Space which shall have accrued prior to the Contraction
Effective Date (or such later date on which Tenant actually surrenders possession of the Contraction Space) irrespective of whether such amounts are ascertainable as of the Contraction Effective Date. 

  

	 	(d)	From and after the Contraction Effective Date, the Contraction Space shall no longer be deemed a part of the Premises, and 

  

	 	(e)	From and after the Contraction Effective Date, neither Landlord nor Tenant shall have any further rights or obligations under this Lease with respect to the Contraction Space except
to the extent provided in Article 35 hereof. 

 (iv) Following the Contraction Effective Date, and within thirty
days following written request by either Landlord or Tenant after either such date, as the case may be, Landlord and Tenant shall enter into a mutually acceptable supplement to this Lease confirming the deletion of the Contraction Space from the
Premises pursuant hereto. The failure or refusal by either party to do so, however, shall not affect the validity of the deletion of the Contraction Space from the Premises. 
 (M) Mandatory Surrender of 46th Floor. 
 (i) Tenant acknowledges that its leasing of the Contraction Space is subject and subordinate to the rights thereto
held by Mayer Brown pursuant to Paragraph 35(B)(i) of the Mayer Brown Lease as originally entered into (the “MB 46th Floor Expansion Right”). If Mayer Brown timely exercises the MB 46th Floor Expansion Right, Landlord, within ten
(10) days following its receipt from Mayer Brown of its written exercise of the MB 46th Floor Expansion Right, shall so notify Tenant in writing (the “MB 46th Floor Option Notice”) and shall furnish to Tenant a copy of the written exercise by Mayer Brown, whereupon Tenant shall be obligated to surrender
possession of the Contraction Space as herein provided. Landlord shall designate in such MB 46th Floor Option Notice (a) the date (the “Required Contraction Effective Date”) on which Tenant shall be scheduled, subject to
Paragraph 35(J)(ii)(a) below, to surrender possession of the Contraction Space to Landlord, (b) three (3) options of premises located on the 22nd through the 45th floors of the Building, inclusive, from which Tenant shall have the right to select the 46th Floor Replacement Premises (the “Possible 46th Floor Replacement Premises”) if Tenant elects to exercise the 46th Floor Replacement Option pursuant to Paragraph 35(K) below, and (c) the 46th Floor Replacement Option Scheduled Delivery Date applicable to each Possible 46th Floor Replacement Premises. Each of the Possible 46th Floor Replacement Premises (a) shall consist of not less than 15,500 square feet nor more than 33,000 square
feet of Rentable Area, 

  

 126 

 
(b) shall be reasonably configured from the core of the Building to the exterior wall of the Building, (c) shall have an RU Ratio equal to or less
than 110% if the Possible 46th Floor Replacement Premises comprises a full floor of the Building, (d) shall be directly visible and accessible from the elevator vestibule of the floor on which such Possible 46th Floor Replacement Premises are located, and (e) shall not be subordinate to any right of first offer in favor of
Mayer Brown or any other tenant or occupant of the Building. 
 (ii) If Landlord timely delivers the MB 46th Floor Option
Notice to Tenant, then, 
  

	 	(a)	 Tenant shall surrender possession of the Contraction Space in accordance with the terms and provisions of Article 13 hereof. If Tenant fails to surrender possession
of the Contraction Space on or before the date (the “46th Floor Surrender
Date”) that is the later to occur of (x) the Required Contraction Effective Date, and (y) if Tenant shall have exercised the 46th Floor Replacement Option, the 46th Floor Replacement Option Rent Commencement Date, Tenant shall be deemed a holdover tenant in such Contraction Space, and shall be
liable to Landlord for all damages resulting from such holdover after the 46th Floor
Surrender Date, subject to the provisions and limitations applicable thereto in Article 14 hereof. From and after the Required Contraction Effective Date (or such later date on which Tenant actually surrenders possession of the Contraction Space),
Tenant’s Pro Rata Share shall be appropriately adjusted and the Net Rent due and payable hereunder shall be reduced by an amount per annum equal to the product obtained by multiplying (i) the number of square feet of Rentable Area in the
portion of the High-Rise Premises so recaptured, and (ii) the Allocated High-Rise Premises Net Rent, 

  

	 	(b)	 Tenant, notwithstanding its surrender of the Contraction Space, shall remain liable for all Rent allocable to the Contraction Space which shall have accrued prior
to the 46th Floor Surrender Date (or such later date on which Tenant actually
surrenders possession of the Contraction Space) irrespective of whether such amounts are ascertainable as of the 46th Floor Surrender Date, 

  

	 	(c)	from and after the 46th Floor Surrender Date, the Contraction Space shall no longer be deemed a part of the Premises, and 

  

	 	(d)	from and after the 46th Floor Surrender Date, neither Landlord nor Tenant shall have any further rights or obligations under this Lease with respect to such Contraction Space except
to the extent provided elsewhere in this Article 35. 

  

 127 

 (iii) Following the 46th Floor Surrender Date, and within thirty days following written
request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually acceptable supplement to this Lease confirming the deletion of the Contraction Space from the Premises pursuant hereto. The failure or refusal by either party to
do so, however, shall not affect the validity of the deletion of the Contraction Space from the Premises. 
 (N)
46th Floor Replacement Option. If
(i) Tenant shall not have assigned this Lease (other than pursuant to Paragraph 21(C)), (ii) Landlord shall have forced Tenant to surrender possession of the Contraction Space pursuant to Paragraph 35(J) above by timely delivering to
Tenant the MB 46th Floor Option Notice, and (iii) this Lease shall then be in
full force and effect, then Tenant shall have the one-time option (the “46th Floor
Replacement Option”) to expand the Premises to include the 46th Floor Replacement Premises upon the following terms and conditions: 
 (i) The
term “46th Floor Replacement Option Scheduled Delivery Date” shall mean the date designated by Landlord as the date on which Landlord intends to deliver the 46th Floor Replacement Premises to Tenant, which date shall be any date no
later than the 120th day prior to the Required Contraction Effective Date. Landlord’s notice shall be irrevocable and shall relate to the entire 46th Floor Replacement Premises. 
 (ii) Tenant shall exercise the 46th Floor Replacement Option, if at all, by delivery to Landlord of a written notice
of exercise (the “46th Floor Replacement Notice”) on or before the later to occur of (a) the 60th day following Tenant’s receipt of the MB 46th Floor Option Notice, and (b) the 365th day preceding the Required Contraction Effective Date. If Tenant fails to deliver the 46th Floor Replacement Notice by such date,
Tenant shall be deemed to have waived its 46th Floor Replacement Option. Tenant shall designate in such 46th Floor Replacement Notice its selection of the space that will constitute the 46th Floor Replacement Premises from the Possible
46th Floor Replacement Premises designated by Landlord pursuant to Paragraph
35(J)(i) above. 
 (iii) If Tenant timely exercises the 46th Floor Replacement Option, then (i) on the 46th Floor
Replacement Option Scheduled Delivery Date, Landlord shall deliver the 46th Floor Replacement Premises to Tenant with all Base Building Work therein complete and otherwise in “as-is” condition, and (ii) the 46th Floor Replacement
Premises shall be included in the Premises upon the same terms, covenants and conditions as are applicable to the Premises, except to the extent, if any, otherwise provided below: 
  

	 	(1)	the term of the letting of the 46th Floor Replacement Premises shall expire on the Initial Expiration Date, subject to extension of the Term pursuant to Paragraphs 35(F) and 35(G);

  

 128 

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses, with respect to the 46th Floor Replacement Premises, shall commence to be payable on the date (the
“46th Floor Replacement Option Rent Commencement Date”) which is the earlier of: 

  

	 	(a)	the date which is one hundred fifty (150) days after the later of (x) the date on which Landlord actually tenders possession of the 46th Floor Replacement Premises to
Tenant in the condition required by this Paragraph 35(K)(iii), and (y) the 46th Floor Replacement Option Scheduled Delivery Date, and 

  

	 	(b)	the date Tenant commences to conduct ordinary business in the 46th Floor Replacement Premises, 

  

	 	(3)	The amount of Net Rent per square foot of Rentable Area with respect to the 46th Floor Replacement Premises shall be equal to that applicable to the Mid-Rise Premises, as such Net
Rent increases from time to time as set forth in Exhibit B-1. 

  

	 	(4)	The Rentable Area of the Premises shall be adjusted by the Rentable Area of the 46th Floor Replacement Premises; 

  

	 	(5)	Tenant’s Pro Rata Share shall be adjusted to reflect the Rentable Area of the 46th Floor Replacement Premises, effective as of the 46th Floor Replacement Option Rent
Commencement Date; and 

  

	 	(6)	 Landlord shall pay to Tenant the 46th Floor Replacement Premises Allowance. The 46th Floor Replacement Premises Allowance shall be used and disbursed in accordance with
the provisions and procedures applicable to the Expansion Allowance set forth in the Workletter; provided, however, that Tenant shall have the right to apply all or any portion of the 46th Floor Replacement Premises Allowance as a credit against the
Rent hereunder. 

 Following exercise by Tenant of the 46th Floor Replacement Option, and within thirty
(30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the 46th Floor Replacement Premises pursuant hereto and the terms
and conditions of such leasing provided for herein. The failure or refusal of either party to do so, however, shall not affect the validity of the leasing of the 46th Floor Replacement Premises. 
 (iv) Landlord may lease the 46th Floor Replacement Premises, or portions thereof, from time to time to third parties so long as such space
is scheduled to be available to be leased to Tenant pursuant to Tenant’s 46th Floor Replacement Option. So long as Landlord has not granted any person rights which conflict with Tenant’s 46th Floor Replacement Option, Landlord shall have
no liability to Tenant, and Landlord shall not be deemed to be in default under this Lease, if it is unable to deliver the 46th Floor Replacement Premises to Tenant on the 46th Floor Replacement Option Scheduled Delivery Date due solely to the
failure 

  

 129 

 
of any tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver possession of the Expansion
Premises in the condition required by Paragraph 35(K)(iii) by the date which is the 90th day after the 46th Floor Replacement Option Scheduled Delivery Date (as such date is extended by Unavoidable Delays), Tenant shall have the option either,
as it may elect (a) by notice to Landlord given at any time prior to the delivery to Tenant of the 46th Floor Replacement Premises in the condition required by Paragraph 35(K)(iii), to rescind its previous exercise of the 46th Floor
Replacement Option, in which event Landlord shall have no liability to Tenant on account of such failure to deliver timely (except that Landlord shall not be released from such liability if it shall have granted any person rights which conflict with
Tenant’s 46th Floor Replacement Option) and shall have no further obligation to deliver the 46th Floor Replacement Premises, or (b) to lease from Landlord on a temporary basis and at the same rent other space in the Building, to the extent
available, that is comparable in size to the 46th Floor Replacement Premises. Landlord will use commercially reasonable efforts to regain possession of the Expansion Premises as promptly as reasonably possible, including the prosecution of
litigation against any occupant of such space. 
 (v) The term “46th Floor Replacement Premises Allowance” shall mean the amount
equal to the product of (i) $62 per square foot of rentable area in the 46th
Floor Replacement Premises, and (ii) a fraction, the numerator of which is the number of full calendar months remaining in the Initial Term hereof (without regard to any extension or renewal thereof) following the 46th Floor Replacement Premises Rent Commencement Date and the denominator of which is 180. 

 (vi) The term “46th Floor Replacement Premises” shall mean the space selected by Tenant from the
three (3) options for the 46th Floor Expansion Premises furnished to Tenant by
Landlord concurrently with Landlord’s delivery to Tenant of the MB 46th Floor
Option Notice. 
 (O) Divided Floors. 
 (i) If the Premises shall include some, but not all, of the office areas on a floor and thereafter shall come to include all of the office
areas on any floor then the Premises shall be deemed also to include the elevator lobby, common corridor and other areas which, on a divided floor, would constitute Common Area (but, if and to the extent under the Measurement Method the entire
rentable area of the floor is already borne by the office areas, such inclusion shall not cause the Rentable Area of the Premises to increase). 
 (ii) No provision of this Article 35 which authorizes Landlord to lease any portion of the Building to any third party shall include, on any divided floor, the portion thereof required for Common Areas. 
  

 130 

 (iii) In the event Tenant from time to time hereunder shall exercise an Expansion Option
for less than all of the Rentable Area on any floor of the Building, then, on or before the Expansion Option Rent Commencement Date, Landlord shall construct and finish in accordance with Building standards all corridors, elevator lobbies and other
Common Areas on the floor in which such Expansion Premises are located and required for the same to be occupied as a multi-tenant floor. In addition, Landlord will cause the interior face (i.e., facing the Premises) of any demising walls constructed
in connection with the foregoing work to be drywalled, taped, spackled and made ready for the application of paint. The cost of the foregoing work shall be paid by Landlord. 
 (P) Tenant’s Right to Lease from Building Tenants. Notwithstanding any provision of any lease or other agreement which may give Landlord the
right to withhold consent to any sublease to Tenant, or any assignment of any lease to Tenant, or any right to recapture (by any means) the premises proposed to be subleased to Tenant or the premises covered by any lease proposed to be assigned to
Tenant, Landlord agrees that (i) it shall consent to any such sublease or assignment and shall not exercise any such recapture right unless required to do so under any Permitted Superior Expansion Right, and (ii) that Tenant may furnish a
copy of this Paragraph 35(M) to any Building tenant, and any such Building tenant may rely thereon. 
 ARTICLE 36.

 Determination by Arbitration 
 (A) Accepted Offer Space. 
 If pursuant to Paragraph 35(E) the Fair Market Rental Value of any
Accepted Offer Space is to be determined pursuant to this Article 36 then on the 20th Business Day after the last day of the Accepted Offer Space Negotiation Period, Landlord and Tenant shall, at the Building’s management office, each
simultaneously submit to the other, in a sealed envelope, its signed written good faith estimate of the Fair Market Rental Value (the “Accepted Offer Space Estimates”). Each Accepted Offer Space Estimate shall consist of either
(i) a single fixed amount, expressed in dollars and cents per square foot of Rentable Area, or (ii) a single amount, expressed in dollars and cents per square foot of Rentable Area, with specified percentage increases at specified
intervals. 
 Landlord and Tenant, within fifteen (15) Business Days after the exchange of Estimates, shall each select a commercial
real estate broker to determine which of the two Estimates most closely reflects the Fair Market Rental Value for the Accepted Offer Space. 
 (B) Renewal Period. 
 If pursuant to Paragraph 35(F) or (G) the Fair Market Rental Value for
any Renewal Period is to be determined pursuant to this Article 36 then on the 75th day after the date of the exchange of Preliminary Estimates (or, if such day is not a Business Day, on the next Business Day), Landlord and Tenant shall, at the Building’s management office, each simultaneously submit to the other, in
a sealed envelope, its written good faith estimate of the Fair Market Rental Value (the “Renewal Term Estimates”), subject to the provisions of the next paragraph. 
  

 131 

 Each Renewal Term Estimate shall consist of only a single fixed amount, expressed in dollars and cents
per square foot of Rentable Area. Landlord’s Renewal Term Estimate shall not be more than 105%, and shall not be less than 95%, of Landlord’s Preliminary Estimate. Tenant’s Renewal Term Estimate shall not be more than 105%, and shall
not be less than 95%, of Tenant’s Preliminary Estimate. If either party shall submit a Renewal Term Estimate which violates the provisions of this paragraph, such Renewal Term Estimate shall be disregarded and such party shall instead be deemed
to have submitted a Renewal Term Estimate equal to its Preliminary Estimate. 
 If the higher of such Estimates is not more than one hundred
five percent (105%) of the lower of such Estimates, then Fair Market Rental Value shall be the average of the two Estimates. 
 If the
Fair Market Rental Value is not so resolved pursuant to the preceding paragraph, Landlord and Tenant, within fifteen (15) Business Days after the exchange of Estimates, shall each select a commercial real estate broker to determine which of the
two Estimates most closely reflects the Fair Market Rental Value for the Renewal Term. 
 (C) Selection of More Accurate Estimate.

 Each broker selected pursuant to this Article 36 shall have had at least five (5) years experience within the previous ten
(10) years as a commercial real estate broker working in the downtown Chicago, Illinois office market, with working knowledge of current rental rates and market practices. 
 Upon selection, Landlord’s and Tenant’s brokers shall work together in good faith to agree upon which of the two Estimates most closely
reflects the Fair Market Rental Value. The Estimate chosen by such brokers shall be binding on both Landlord and Tenant as the Net Rent for the Accepted Offer Space or the Renewal Period in question. 
 If either Landlord or Tenant fails to appoint brokers within the fifteen (15) Business Day period referred to above and such failure continues for
fifteen (15) Business Days after notice thereof is received by the party so failing, a broker appointed by the other party shall be the sole broker for the purposes hereof. 
 If the two (2) brokers fail to agree upon which of the two Estimates most closely reflects the Fair Market Rental Value within twenty (20) days
after their appointment, then, within ten (10) days after the expiration of such twenty (20) day period, the two (2) two brokers shall select a third (3rd) broker meeting the aforementioned criteria (or, if such two
(2) brokers are unable to select a third (3rd) broker, such selection shall be made by the President of the Chicago chapter of American Appraisal Institute (or its successor organization)). Once the third (3rd) broker has been
selected as provided for above, then, as soon thereafter as practicable but in any case within fourteen (14) days, the broker shall make his determination of which of the two Estimates most closely reflects the Fair Market Rental Value and such
broker shall not select anything other than one of the two Estimates from Landlord and Tenant and such Estimate shall be binding on both Landlord and Tenant as the Fair Market Rental Value for the Accepted Offer Space . If the third
(3rd) broker believes that expert advice would materially assist him/her, such broker may retain one or more qualified persons, to provide such expert advice. 
  

 132 

 Each party shall pay one-half (1/2) of the costs of the third (3rd) broker and of any experts
retained by the third (3rd) broker. Any fees of any broker, counsel or experts engaged directly by Landlord or Tenant, however, shall be borne by the party retaining such broker, counsel or expert. 
 ARTICLE 37. 
 Parking 

 Landlord shall provide or cause to be provided to Tenant the Parking Space Limit number of reserved parking spaces in the garage within
the Building at locations reasonably determined by Landlord taking into consideration Tenant’s reasonable requests. Tenant shall be entitled to use such parking spaces in accordance with the terms of the Terms of Parking License attached hereto
as Exhibit P-2 (the “Terms of Parking License”) and, except as otherwise provided in the Terms of Parking License, each such space shall be a reserved space and Tenant shall be entitled to use such parking spaces at all
times. 
 The term “Parking Space Limit” shall mean 45 parking spaces, plus one parking space for each 11,000 square feet of
Rentable Area (or majority portion thereof) included in the Premises, in excess of 292,227 square feet of Rentable Area. 
 Tenant shall pay
Landlord for the use of such parking spaces, the monthly rates established by Landlord, from time to time, which shall not be in excess of the prevailing rates for a comparable parking garages in the vicinity of the Building, and shall be no more
than the monthly rates charged to any other tenant leasing in excess of 100,000 square feet of Rentable Area. 
 Notwithstanding the
foregoing, commencing any time after the date of this Lease, from time to time, on not less than thirty (30) days notice to Landlord, Tenant may elect to reduce the number of spaces that it uses or, if it is then using less than the Parking
Space Limit, to increase the number of spaces that it uses, provided that 
 (i) Tenant may not increase the number of spaces
it uses to more than the Parking Space Limit, and 
 (ii) Tenant’s right to increase the number of parking spaces it
uses, if it shall at any time be using less than the Parking Space Limit, shall be subject to availability of such parking spaces. 
 Whenever the number or designation of the parking spaces being licensed to Tenant shall change, Landlord and Tenant shall enter into a Confirmation in the form of Exhibit P-1 hereto to evidence the same. 
 Landlord shall limit use of the garage within the Building or any other parking facilities on the Land (the “Building Parking
Facilities”) to employees of Building tenants who purchase parking privileges on a monthly basis and employees of the Building’s management agent. 
  

 133 

 Landlord shall provide security to the Building Parking Facilities in accordance with Exhibit S.

 ARTICLE 38. 
 Roof
Satellite Dish/Antennae 
 Tenant shall have access and use of 
  

	 	(a)	the portion of the Building’s roof designated for the installation of radio, microwave and other communications equipment, depicted on page A2.49 of the Existing Drawings, for
the erection and maintenance of Tenant’s Permitted Antennas for use by Tenant or other bona-fide office occupants of the Premises, for the transmission and receipt of radio, microwave and other communication signals, and

  

	 	(b)	Tenant’s Pro Rata Share of the Building SatPOP Room and the Building Telecommunications Wiring Room for the installation of conduits from Tenant’s Permitted Antennas to
the Premises. 

 As used herein the term “Tenant’s Permitted Antennas” shall refer to such antennas as
Tenant shall reasonably require. 
 ARTICLE 39. 
 Intentionally Omitted 
 ARTICLE 40. 
 Building Address; Building Name 
 The Building has been designated by the United States Postal Service to have a street address of 71 South Wacker Drive, and Landlord shall not take any action, at any time during the Term, to change the street address of the Building.
Tenant may refer to the Building either by its address and/or, so long as the Building has a name, by its name (as Tenant shall elect). 
 The Building shall be (a) called “Hyatt Center” or another name referring to “Hyatt” or (b) named after an entity acquiring all or substantially all of the hotel management or hospitality business
assets operated under the “Hyatt” tradename, subject to the third paragraph of this Article 40. 
  

 134 

 Landlord represents, and Tenant acknowledges, that Hyatt Corporation has granted and does hereby grant to
Landlord and any wholly-owned subsidiary of Landlord a revocable license for it, its subsidiary, and its tenants, subtenants and occupants to use the “Hyatt” tradename as or as a part of the name of the Building and as part of the name of
the property management company that manages the Building. This provision shall survive the termination of this Lease. 
 Landlord, at any
time and from time to time, (a) may elect to operate the Building without a name, in which case the Building shall be known only by its street address, and (b) may name the Building after any other tenant of the Building which leases in

provisions of Article 21 respecting Transfers. 
 (B) No Recording. This Lease shall not be recorded. Upon Tenant’s request,
Landlord and Tenant shall join in a memorandum hereof for recording in form and substance reasonably satisfactory to Landlord and Tenant. Such memorandum shall contain all provisions required by law to be included therein and shall also include such

 136 

 (E) Amendments. This Lease shall not be amended, changed or modified in any way unless in writing
executed by Landlord and Tenant. 
 (F) Survival of Obligations. Any obligations of Landlord and Tenant accruing prior to the
expiration or earlier termination of the Lease shall survive the expiration or earlier termination of the Lease, and Landlord and Tenant shall promptly perform all such obligations whether or not this Lease has expired or been terminated.

 (G) No Joint Venture. Nothing contained in this Lease shall be deemed or construed by the parties to this Lease, or by any third
party, to create the relationship of principal and agent, partnership, joint venture, 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 acts of the parties to this Lease shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord and tenant. 
 (H) Interpretation. Landlord and Tenant have jointly participated in the drafting of this Lease. Accordingly, this Lease shall be construed
neither for nor against Landlord or Tenant notwithstanding the party which drafted same, but shall be given a fair and reasonable interpretation in accordance with the meaning of its terms and the intent of the parties.

provisions, and the table of definitions are included for convenience and are not part of this Lease. 
 (K) Full Agreement. This
Lease contains all the agreements and understanding between Landlord and Tenant relating to the matters set forth herein and no prior or contemporaneous agreement or understanding pertaining to the same shall be of any force or effect, except any
such contemporaneous written agreement specifically referring to and modifying this Lease, signed by both parties. Without limitation as to the generality of the foregoing, Tenant hereby acknowledges and agrees that Landlord’s leasing agents
and field personnel are only authorized to show the Premises and negotiate terms and conditions for leases subject to Landlord’s final approval, and are not authorized to make any agreements, representations, understandings or obligations,
binding upon Landlord, respecting the condition of the Premises or Property, suitability of the same for Tenant’s business, or any other matter, and only such agreements, representations, understandings or obligations expressly contained herein
or in such contemporaneous agreement shall be of any force or effect. This Lease may not be modified, except in writing signed by both parties. 
  

 137 

 (L) Counterparts. This Agreement may be executed in several counterparts, and all so executed
shall constitute one agreement, binding on all parties hereto, notwithstanding that all parties are not signatories to the original or the same counterpart. Only one such counterpart may be required as proof of the existence and terms of this Lease.

 (M) No Promotion. Landlord and Tenant each agree that neither it, nor any agent, contractor or representative (including, in the
case of Landlord, Landlord’s leasing agent) shall, without the prior written consent of the other party in each instance, (i) use in advertising, publicity, or otherwise the name of the other party, or any Affiliate of the other party, or
any partner or employee of the other party, or any tradename, trademark, trade device, service mark, symbol or any abbreviation, contraction or simulation thereof; provided, however, Landlord may include Tenant in any tenant list or rent roll given
to potential purchasers or lenders; or (ii) represent, directly or indirectly, that any product or any service provided by it has been approved or endorsed by the other party. This provision shall survive termination of this Lease. 

(N) Confidentiality. Landlord acknowledge that it or its agents or contractors (or employees of Landlord or of its agents or contractors) may,
in the course of performing their responsibilities under this Lease, be exposed to or acquire information which is proprietary to or confidential to Tenant or its affiliated companies or their clients or to third parties to whom Tenant or its
affiliated companies owe a duty of confidentiality. Any and all non-public information of any form obtained by Landlord or its agents or contractors (or any such employees) in the performance of its responsibilities under this Lease shall be deemed
to be confidential and proprietary information. Landlord agrees that it and its agents and contractors (i) shall hold such information in strict confidence and shall not copy, reproduce, sell, assign, license, market, transfer or otherwise
dispose of, give or disclose such information to third parties or use such information for any purposes whatsoever (other than the provision of services to Tenant as contemplated by this Lease) and (ii) shall advise each of its employees who
may be exposed to such proprietary and confidential information of their obligations to keep such information confidential. This provision shall survive termination of this Lease. 
 (O) Tenant and Landlord Authority. Tenant represents and warrants that this Lease has been duly authorized, executed and delivered by and on
behalf of Tenant and constitutes the valid and binding agreement of Tenant in accordance with its terms. Landlord represents and warrants that this Lease has been duly authorized, executed and delivered by and on behalf of Landlord and constitutes
the valid and binding agreement of Landlord in accordance with its terms. Each of Landlord and Tenant further represents and warrants to the other that it is duly organized, existing and is in good standing under the laws of the state in which the
Property is located, and covenants and agrees that it shall maintain such existence and good standing throughout the Term. 
 (P) Business
Day. As used herein, the term “Business Day” shall mean any day other than a Saturday, Sunday, any federal or State of Illinois holiday, or any day on which banking institutions in the State of Illinois are closed for business
with the general public. If any period expires on a day which is not a Business Day, or any event or condition is required by the terms of this Lease to occur or be fulfilled on a day which is not a Business Day, such period shall expire, or such
event or condition shall occur or be fulfilled, as the case may be, on the next succeeding Business Day; provided, however, that this sentence shall not apply to those provisions of this Lease which contemplate performance on a non-Business Day,
e.g., various provisions of Article 6.

	 	d.	If the Design Development Drawings so submitted to Tenant conform to the Minimum Requirements, then Tenant shall not unreasonably withhold its approval thereof; except, that Tenant
shall not be deemed to have unreasonably withheld its approval thereof if Tenant disagrees in good faith with the aesthetic characteristics or style of, any portion of the Design Development Drawings that (1) omit or change (including any

	 	g.	If Landlord believes that Tenant is not entitled to withhold its approval, such dispute shall be subject to resolution pursuant to the Workletter Dispute Procedures, and if such
dispute is resolved in Landlord’s favor:

	 	d.	If the Construction Documents so submitted to Tenant conform to the Minimum Requirements, then Tenant shall not unreasonably withhold its approval thereof; except, that Tenant shall
not be deemed to have unreasonably withheld its approval thereof if Tenant disagrees in good faith with the aesthetic characteristics or style of, any portion of the Construction Documents that (1) omit or change (including any change made from

(5) Business Days. 

  

	 	g.	If Landlord believes that Tenant is not entitled to withhold its approval, then such dispute shall be resolved through the Workletter Dispute Procedures, and if such dispute is

THE WORKLETTER SHALL CONSTITUTE APPROVAL” and 

	 	ii.	specifically identify each respect in which such Design Development Drawings or such Construction Documents or such Landlord Work Change do(es) or may not conform to the Minimum
Requirements by referring to the accompanying drawing on which such non-conformity is bubbled or to the section of the accompanying specifications in which such non-conformity is set forth (each such non-conformity so identified being herein called
a “Proposed Section 4 Change”). 

  

	 	b.	If Landlord delivers a Section 4 Notice, then Tenant shall have fifteen (15) Business Days from its receipt of such Section 4 Notice to approve or disapprove the

(5) additional Business Days following its receipt of such Final Section 4 Notice, then Tenant shall be deemed to have approved said Proposed Section 4 Change so identified. 

  

	 	e.	Any Proposed Section 4 Change approved by Tenant is herein called an “Approved Section 4 Change.” 

	 	f.	Tenant’s approval or disapproval of any Proposed Section 4 Change identified on any Section 4 Notice shall not (except as to the matters covered by the Proposed
Section 4 Changes) constitute or affect Tenant’s approval or disapproval of the Design Development Drawings or the Construction Documents or Landlord Work Change enclosed therewith, which shall (except as to the matters covered by the
Proposed Section 4 Changes) be governed by Section 2, 3 or 7 of this Workletter, as the case may be. 

  

	5.	Phased Plans. 

  

	 	a.	Landlord shall submit the Design Development Drawings in one package, except as otherwise set forth in Section 5.b. Landlord shall submit the Construction Documents in phases

or, in the case of any approval with conditions, as provided for in Section 2.h, until Tenant approves the Design Development Drawings as to the matters to which such phase of the Construction Documents relates. 

  

	 	b.	Tenant has heretofore approved the steel, curtainwall and elevator Design Development Drawings listed on Exhibit B hereto; except, that (i) Landlord did not notify
Tenant of any failure of such Design Development Drawings to conform to the Minimum Requirements, and (ii) Tenant is not deemed to have approved any failure of such Design Development Drawings to conform to the Minimum Requirements.

  

	6.	Construction of Landlord Work. Landlord shall perform Landlord’s Work, 

  

	 	a.	with diligence and continuity; 

  

	 	b.	in accordance with the requirements of this Workletter; and 

  

	 	c.	in accordance with the Construction Documents approved by Tenant, as modified from time to time, pursuant to any Tenant Change Order or Landlord Work Changes, in each case approved
by Tenant pursuant to this Workletter, or by any Landlord Work Changes; 

 except, that (1) if and to the extent that the
Construction Documents approved by Tenant do not conform to the Minimum Requirements then, except for any Approved Section 4 Changes, Landlord shall nonetheless be required to perform Landlord’s Work in accordance with the Minimum
Requirements, and (2) Landlord shall not install any portion of Landlord’s Work until Tenant approves the Construction Documents for such portion thereof. Landlord shall not perform any work other than Landlord Work and Excluded Work. If
Landlord performs any work that violates the terms of this Section 6 (“Improper Landlord Work”), then Landlord shall, upon Tenant’s demand, remove or correct the same as may be required in order to conform to this
Section 6; except, that Landlord shall not be required (A) to remove or correct any such violation relative to Landlord’s 

 
Work that under Section 13 Tenant is deemed to have accepted, or (B) to remove or correct any such violation that (i) is Excluded Work other
than the Fitness Center and Cafeteria, (ii) conforms to the Minimum Requirements, and (iii) will not adversely affect Tenant or its use or occupancy of the Premises. 
  

	7.	Landlord Changes. 

  

	 	a.	The term “Landlord Work Change” means any change in the Construction Documents for any portion of Landlord’s Work (or in any portion of Landlord’s Work)
after Tenant’s approval of the Construction Documents for such portion of Landlord’s Work. 

  

	 	b.	The term “Permitted Landlord Work Change” means any minor field change (as such term is understood in the industry) other than any that 

  

	 	i.	is located in the Premises or on a floor upon which any portion of the Premises is located, or 

  

	 	ii.	does not conform to the Minimum Requirements. 

  

	 	c.	Landlord shall promptly submit to Tenant each Landlord Work Change to Tenant that is not a Permitted Landlord Change. 

  

	 	d.	Each Landlord Work Change that is not a Permitted Landlord Work Change shall be subject to Tenant’s approval in accordance with Section 3 of this Workletter (specifically
including Section 3.d and Section 3.i); except that for purposes of any such Landlord Work Change 

  

	 	i.	the notice referred to in Section 3.b (the “Section 7 Notice”) shall (i) be entitled “NOTICE UNDER WORKLETTER SECTION 7”, (ii) refer to the
Landlord Work Change rather than to Construction Documents, and (iii) refer to five (5) Business Days rather than fifteen (15) Business Days; and 

  

	 	ii.	the period provided for in Section 3.c shall be shortened to five (5) Business Days. 

  

	 	e.	Permitted Landlord Work Changes shall not be subject to Tenant’s approval. Landlord shall submit to Tenant copies of all Landlord Work Changes (excluding any thereof not
reduced to writing) at such intervals as Landlord shall determine, but not less frequently than monthly. 

  

	8.	Tenant Change Orders. 

  

	 	a.	The term “Tenant Change Order Cost Adjustment” means, subject to Section 8.e. hereof, the increase or decrease, if any, in Landlord’s Costs (after
offsetting any deductive changes) resulting from a Tenant Change Order, each of which shall be itemized in reasonable detail, as set forth in Landlord’s notice under Section 8.k or, if Tenant shall have disputed the same pursuant to
Section 8.m, as determined pursuant to the Workletter Dispute Procedures. 

	 	b.	The term “Tenant Change Order Delivery Date Time Adjustment” means, subject to Section 8.e. hereof, the number of days by which any Segment Delivery Date is or
will be delayed or accelerated by reason of a Tenant Change Order, as set forth in Landlord’s notice under Section 8.k or, if Tenant shall have disputed the same pursuant to Section 8.m, as determined pursuant to the Workletter
Dispute Procedures. 

  

	 	c.	The term “Tenant Change Order Substantial Completion Date Time Adjustment” means, subject to Section 8.e. hereof, the number of days by which the Substantial
Completion Date is or will be delayed or accelerated by reason of a Tenant Change Order, as set forth in Landlord’s notice under Section 8.k or, if Tenant shall have disputed the same pursuant to Section 8.m, as determined pursuant to
the Workletter Dispute Procedures. 

  

	 	d.	The term “Tenant Change Order Commencement Date Time Adjustment” means, subject to Section 8.e. hereof, the number of days by which the Commencement Date is or
will be delayed or accelerated by reason of a Tenant Change Order, as set forth in Landlord’s notice under Section 8.k or, if Tenant shall have disputed the same pursuant to Section 8.m, as determined pursuant to the Workletter
Dispute Procedures. 

  

	 	e.	The Tenant Change Order Cost Adjustment, the Tenant Change Order Delivery Date Time Adjustment, the Tenant Change Order Substantial Completion Date Time Adjustment and the Tenant
Change Order Commencement Date Time Adjustment shall each be determined based on the assumption that Landlord has or will use commercially reasonable efforts to mitigate the extent of the delay and costs arising out of any Tenant Change Order
(excluding mitigation measures that would result in Landlord incurring Landlord Costs that, following Landlord’s request, Tenant has refused to agree to pay in an instrument reasonably acceptable to Landlord). Prior to the final determination
of the Tenant Change Order Cost Adjustment, the Tenant Change Order Delivery Date Time Adjustment, the Tenant Change Order Substantial Completion Date Time Adjustment and the Tenant Change Order Commencement Date Time Adjustment relative to any
Tenant Change Order, Landlord and Tenant shall cooperate in identifying such mitigation measures. 

  

	 	f.	Tenant, at Tenant’s sole cost and expense, at any time prior to the Commencement Date, may request (a “Tenant Change Order Request”) changes in Landlord’s
Work (a “Tenant Change Order”). Each Tenant Change Order Request shall be in writing and shall contain sufficient detail for Landlord to prepare the changes to the Construction Documents necessary to effect the requested change in
Landlord’s Work (the “Tenant Change Order Requirements”), and shall be accompanied by a separate notice (a “Section 8.f Notice”) entitled “NOTICE UNDER WORKLETTER SECTION 8.f” that shall

	 	i.	contain the following statement directly below such title: “THE TENANT CHANGE ORDER REQUESTS INCLUDED WITH THIS NOTICE ARE BEING SUBMITTED UNDER SECTION 8.f. OF THE 71 SOUTH
WACKER WORKLETTER. YOUR APPROVAL OR DISAPPROVAL IS REQUIRED WITHIN FIVE (5) BUSINESS DAYS. YOUR FAILURE TO APPROVE OR DISAPPROVE WITHIN SAID FIVE (5) BUSINESS DAYS SHALL CONSTITUTE APPROVAL.”, and 

  

	 	ii.	list each Tenant Change Order Request being submitted. 

 If
Landlord believes that the Tenant Change Order Request does not conform to the Tenant Change Order Requirements, Landlord shall so notify Tenant as soon as reasonably practicable but, in any event, within five (5) Business Days after its
receipt of any Tenant Change Order Request. 
  

	 	g.	Each Tenant Change Order Request shall be subject to Landlord’s approval. Landlord’s approval shall not be unreasonably withheld, provided the related Tenant Change Order
would not violate the Landlord Consent Standards and conforms to the Tenant Change Order Requirements. 

  

	 	h.	Landlord shall have five (5) Business Days after its receipt of any Tenant Change Order Request (or its receipt of such additional detail as Landlord may reasonably request
pursuant to Section 8.e) to approve or disapprove such Tenant Change Order Request, and to notify Tenant of its reasons for withholding approval. Landlord, if it shall disapprove the requested Tenant Change Order Request, shall deliver to
Tenant, concurrently with such notice of disapproval, a reasonably specific statement of its reasons for disapproval and of any specific revisions that Landlord proposes to remedy the matter, but Landlord shall not be required to propose any such
specific revisions. If Landlord does not approve or disapprove the Tenant Change Order Request as provided for in this Section 8.h within the time period provided for in this Section 8.h, then Landlord shall be deemed to have approved the
Tenant Change Order Request. The procedure provided for in this Section 8.h shall be repeated for each revised and resubmitted version of such Tenant Change Order Request until Landlord approves or Tenant withdraws such Tenant Change Order
Request. 

  

	 	i.	If Tenant believes that Landlord shall not be entitled to withhold its approval of any Tenant Change Order Request, then the dispute shall be subject to the Workletter Dispute
Procedures, and if such dispute is resolved in Tenant’s favor, then

Date Time Adjustment, Tenant Change Order Substantial Completion Date Time Adjustment and the Tenant Change Order Commencement Date Time Adjustment. When Landlord delivers the foregoing to Tenant, if Landlord actually knows of potential
modifications to Tenant’s Change Order that are in Landlord’s reasonable judgment not likely to be known by Tenant and that would materially reduce the Tenant Change Order Cost Adjustment, the Tenant Change Order Delivery Date Time
Adjustment. the Tenant Change Order Substantial Completion Date Time Adjustment or the Tenant Commencement Date Time Adjustment, then Landlord shall use commercially reasonable efforts to promptly advise Tenant in writing of such modifications.

  

	 	l.	Within five (5) Business Days of Landlord’s delivery to Tenant of the materials required by Section 8.k, Tenant shall either approve such Tenant Change Order and the
Landlord’s computation of the matters discussed in Section 8.k.(ii) above or withdraw such Tenant Change Order Request by delivering written notice of such approval or withdrawal to Landlord. If Tenant fails to timely deliver any such
written notice, Tenant shall be deemed to have withdrawn such Tenant Change Order Request. If Tenant approves such Tenant Change Order, then, subject to Section 8.m. below, Landlord shall perform the same. 

  

	 	m.	If, by notice delivered to Landlord given concurrently with its written notice approving any Tenant Work Change, Tenant disagrees with Landlord’s computation of the Tenant
Change Order Delivery Date Time Adjustment, Tenant Change Order Substantial Completion Date Time Adjustment, Tenant Commencement Date Time Adjustment, or Tenant Change Order Cost Adjustment, set forth in Landlord’s notice pursuant to
Section 8.k, then Landlord shall nonetheless proceed with the work provided for in any approved Tenant Change Order and the dispute shall be subject to the Workletter Dispute Procedures. If the results of such Workletter Dispute Procedures
differ from Landlord’s response pursuant to Section 8.k, then the results of the Workletter Dispute Procedures shall be applicable for purposes of Section 8.l in lieu of Landlord’s response pursuant to Section 8.k(ii). If
the Workletter Dispute Procedures result in a reduction of ten percent (10%) or more in any foregoing item in dispute, then Landlord shall reimburse Tenant for Tenant’s Costs incurred in prosecuting such Workletter Dispute Procedures;
otherwise, Tenant shall reimburse Landlord for the Landlord’s Costs in the prosecution of such Workletter Dispute Procedures. 

	 	n.	The amount of Tenant’s Change Order Cost Adjustment,

	 	p.	Without Limitation of the other provisions of this Section 8, Landlord agrees that Tenant shall have the right to substitute finishes of, and substitute materials with respect
to, items of Landlord’s Work in the Premises, (the “Landlord Finish Work”) set forth on Exhibit G attached hereto (the “Landlord Finish Schedule”). Landlord shall cooperate reasonably with Tenant so as
to minimize any time adjustments or cost adjustments resulting from any such substitution and Landlord in computing any such cost adjustment shall credit to Tenant an amount equal to any decrease in Landlord’s Costs resulting from such
substitution. Toward that end, Landlord shall notify Tenant not less than fifteen (15) Business Days prior to the date upon which Landlord places its order for an item of Landlord Finish Work set forth in the Landlord Finish Schedule, setting
forth on such notice the items of Landlord Finish Work to be ordered, the date that such item will be ordered, and the unit cost of the relevant item(s) of Landlord Finish Work (the “Landlord Finish Work Notice”). If Tenant elects
to exercise its right to substitute any Landlord Finish Work, Tenant shall submit to Landlord a Tenant Change Order Request with respect thereto in accordance with the terms of Section 8.f above within ten (10) Business Days following
receipt of such notice from Landlord.

work shown on the Initial Development Schedule, Landlord shall deliver to Tenant revised copies of its development schedule showing any expected deviations from the Initial Development Schedule and Landlord’s then best estimate of the Segment

conditions relate until the Tenant Work Plans are approved. 

  

	 	viii.	Without limiting the generality of the foregoing, it is specifically agreed that, subject to the Landlord Consent Standards and Tenant Building Plan Requirements, Tenant’s

	 	2.	for purposes of the Landlord Consent Standards, such Special Tenant Work shall be deemed to constitute a Tenant Change Order. 

  

	 	iv.	If on or before the date Landlord is required to approve or disapprove any Special Tenant Work, Landlord notifies Tenant and demonstrates that Tenant’s performance of the
Special Tenant Work would void any manufacturer’s equipment warranty applicable to any of the Base Building Work, then Landlord may require that such Special Tenant Work be instead performed by Landlord as a Tenant Change Order subject to
Section 8 (in which case the same shall no longer be regarded as Special Tenant Work). 

	 	v.	No Special Tenant Work shall be performed prior to any Segment Delivery Date and, with respect to any floor on which the Premises are located, after Tenant shall have commenced the

Landlord shall have approved the same for such portion of the Tenant Work. The term “Material Tenant Work Change” means any Tenant Work Change that affects Special Tenant Work or that requires a Governmental Approval.

	 	ii.	All Material Tenant Work Plan Changes and any other Tenant Work Changes for which Tenant requests Landlord’s approval shall be subject to Landlord’s approval in accordance
with Sections 15.a through 15.c of this Workletter; except, that for purposes of any such Work Plan Change, the period provided for in Section 15.a.2 shall be shortened to five (5) Business Days. 

  

	 	1.	the notice referred to in Section 15.a (the “Section 15.h Notice”) shall (i) be entitled “NOTICE UNDER WORKLETTER SECTION 15.h”, (ii) refer
to the Tenant Work Change rather than to Tenant Work Plans, and (iii) refer to five (5) Business Days rather than fifteen (15) Business Days; and

Landlord or (b) a Tenant Work Change approved by Landlord (any such work being herein called “Improper Tenant Work”), then Tenant shall, upon Landlord’s demand, remove or correct the same as may be required in order to
conform to the Landlord Consent Standards. 

  

	 	j.	Phased Plans. Tenant may elect to submit Tenant Work Plans in phases (by portion of the Premises or trade or any combination thereof) and, in such a case, the foregoing

in this Section 15 (except for such liability to Landlord as is provided for in this Workletter with respect to an improper exercise of such rights). Additionally, neither review nor approval by Landlord of any of the Tenant Work Plans,
including any Tenant Work Plan Changes, shall constitute a representation or warranty by Landlord that such items either (i) are complete or suitable for their intended purposes, (ii) comply with applicable laws, ordinances, codes and
regulations, or (iii) conform to the requirements of this Workletter, it being expressly agreed by Tenant that Landlord assumes no responsibility or liability whatsoever to Tenant or any other person or entity for such completeness,

Landlord agrees that Tenant may pursue such variance and agrees to cooperate reasonably and in good faith with Tenant, at Tenant’s cost and expense, to
obtain such variance so as to permit the installation of modular wiring within the Premises. Landlord’s cooperation, at Tenant’s sole cost and expense, shall include, (1) submitting (or joining in Tenant’s submission of)

the items reasonable required or requested by the City to evaluate the variance request, including, without limitation, any new drawings, raised floor plans, electrical distribution plans, mock-ups, documents, engineering reports, load calculations,
surveys, and studies, in each case, to the extent required to obtain such variance. If the City’s grant of the foregoing variance requires a change in Landlord’s Work, then any such changes shall be made through delivery of a Tenant Change
Order Request pursuant to Section 8 hereof. Tenant shall indemnify, defend and hold Landlord harmless from and against any liabilities incurred by Landlord as a result of the performance of its obligations under this Section 15.m.

	 	i.	The Tenant Work Allowance shall be payable by Landlord to Tenant, or if requested by Tenant, to any of Tenant’s Contractors, Tenant’s Design Professionals, suppliers,
materialmen, and consultants, in each case, within thirty (30) days following Landlord’s receipt of periodic requisitions (each being herein called a “Tenant Requisition”) therefor submitted by Tenant to Landlord as Tenant
Work progresses, but no more frequently than monthly. 

	 	ii.	Each Tenant Requisition (a) shall state the amount of such Tenant Requisition, (b) shall, as applicable, state the amount payable to each of Tenant’s Contractors,
Tenant’s Design Professionals, suppliers, materialmen, and consultants (and the mailing address thereof) and to Landlord, and (c) shall list the invoices to be paid or reimbursed; except, that if the total amount of such invoices exceeds
the amount of such Tenant Requisition, then Tenant shall be responsible for the payment of the balance thereof. Each Tenant Requisition shall be accompanied by (a) the invoices so listed, (b) with respect to Tenant’s Contractor’s
invoices, a certificate signed by Tenant and Tenant’s Architect certifying that Tenant Work represented by such invoices has been performed in accordance with Tenant Work Plans, (c) a copy of the appropriate Tenant and Tenant Contractor
sworn statements and unconditional lien waivers covering the portion of the work covered by such Tenant Requisition; except, that lien waivers may be submitted on a “30-day delay” basis, so long as Tenant has provided to Landlord’s
title insurer such undertakings and indemnities as the title insurer may require in order to insure over all such liens attributable to work completed to date and represented in such disbursement payment. 

  

	 	iii.	Upon completion of the Tenant Work, Tenant shall furnish Landlord with final waivers of lien and appropriate Tenant and contractor sworn statements, in such reasonable form as may
be reasonably required by Landlord, from all parties performing labor or supplying materials or services in connection with the Tenant Work showing that all of said parties have been compensated in full and waiving all liens in connection with the
Premises and Building.

	 	v.	Before the earlier of the commencement of the construction of the Tenant Work or the submission of any Tenant Requisition, Landlord shall, at its expense, establish a construction
escrow, in customary form, at a title insurance company designated by Landlord, which escrow shall provide for payment of the Tenant Work Allowance, from time to time, to Tenant, Tenant’s Design Professionals, Tenant’s Contractors,
suppliers and consultants, as the case may be, in the manner set forth above, upon the title insurance company’s satisfactory review of lien waivers and sworn statements and upon the title insurance company’s willingness to issue title
insurance over mechanic’s liens relating to Tenant Work through the date of each draw. 

	 	vi.	 If all or any portion of any Tenant Requisition is not paid when due and such failure shall continue beyond the tenth (10th) day after Tenant shall have delivered a Notice of Intended Enforcement under Paragraph 4(K)(iv) of the Lease
with respect thereto, then such unpaid amount shall bear interest at the Default Rate from and after such 10th day until paid. 

  

	 	c.	Ownership of Tenant Work.

the Other Leases is a shared facilities workletter (the “Other Workletters”) in substantially the same form as this Workletter (except for Section 2.b.2 which may differ), and each of the Other Workletters also requires
Landlord to perform the Shared Facilities Work. 

  

	 	b.	As more fully described below: 

  

	 	i.	Landlord shall perform the Shared Facilities Work, and 

  

	 	ii.	Tenant shall reimburse Landlord an amount (“Tenant’s SF Contribution”) equal to one-third of the excess of 

  

	 	1.	the lesser of (i) Landlord’s Costs, or (ii) the Reimbursable Cost Limit, over 

  

	 	2.	the product of (i) $50 per square foot of Rentable Area, multiplied by (ii) the Rentable Area of the Fitness Center Space, the Cafeteria Space and the Circulation Area
(such product being herein called the “Shared Facilities Allowance”). 

  

	 	c.	Notwithstanding any other provision of this Workletter, but subject to Section 3.e.2, regardless of whether Landlord receives any comments, suggestions or instructions from any
of the Participants or by Majority Instrument and regardless of whether doing so shall cause Landlord’s Costs to exceed the Reimbursable Cost Limit, Landlord shall cause the Design Materials and the Shared Facilities to satisfy the Minimum
Requirement. 

  

 D-2-3 

	 	d.	At all reasonable times through the Cafeteria Commencement Date and the Fitness Center Commencement Date, Landlord shall 

  

	 	i.	make itself and its Design Professionals available to the Participants and their design professionals and consultants during regular business hours at the principal offices of
Landlord or at the Building site offices for review and discussion of the design and construction of the Shared Facilities and the Shared Facilities Work and all matters relating to this Workletter; and 

  

	 	ii.	furnish to Tenant and its design professional and consultants all reports, studies, budgets, drawings, specifications and other information relative to the Shared Facilities and the
Shared Facilities Work as any of the Participants shall reasonably request. 

  

	3	Design. 

  

	 	a.	The design of the Shared Facilities shall be a six phase process, as follows:

	 	b.	With respect to each phase: 

  

	 	i.	The term “Design Materials” shall refer to materials regarding the Shared Facilities Work (including both construction items and Fixtures) with a level of detail
consistent with good design practices for the phase in question, including an updated budget. Additionally, with respect to phases 5 and 6, the Design Materials shall include (i) Construction Documents (as defined in the Regular Workletter) and
(ii) full particular on all Fixtures. 

  

	 	ii.	The term “Review and Dialogue Period” shall mean the period commencing upon receipt by the Participants of Landlord’s Design Materials and ending on the
earlier of (i) the date established by Unanimous Instrument, and (ii) the 30th day after the date of such receipt, except that there shall be no Review and Dialogue Period after the submission to the Participants of the phase six Design
Materials and the provisions of Section 4 shall apply in lieu thereof. 

  

 D-2-4 

	 	c.	Landlord shall prosecute the preparation and submission to Tenant of the Design Materials with commercially reasonable diligence. Landlord shall submit the Design Materials for each
phase to all Participants 

  

	 	i.	with respect to the first phase, no later than December 1, 2002, 

  

	 	ii.	with respect to each subsequent phase, no earlier than the end of the Review and Dialogue Period for the prior phase. 

  

	 	d.	In preparing each successive phase, Landlord, subject to Section 2.c, shall: 

  

	 	i.	consider in good faith for adoption all of Tenant’s comments and suggestions given prior to the end of the Review and Dialogue Period for the prior phase, and

  

	 	ii.	comply with all instructions given by Majority Instrument prior to the end of the Review and Dialogue Period for the prior phase, 

 provided, however, that, unless required to satisfy the Minimum Requirement, Landlord shall not be required to comply with any instructions which would
cause Landlord’s Costs to exceed (or to increase the amount by which they exceed) the Reimbursable Cost Limit, unless one or more of the Participants agree to reimburse Landlord for such excess pursuant to a written instrument in form and
substance reasonably satisfactory to Landlord. 
  

	 	e.	The term “Design Failure” shall mean any failure of the Design Materials (i) to satisfy the Minimum Requirements (excluding clause (3) of the definition
thereof), (ii) to conform to the requirements of Section 2.d, or (iii) to include the information or level of detail required by Section 3.b. 

  

	 	i.	Prior to or at the end of the Review and Dialogue Period relative to each of phases 1, 2, 3 and 4 of the Design Materials, Tenant, to the extent that it is reasonably able to
identify any Design Failure relative to the Design Materials for such phase as submitted by Landlord at the beginning of such Review and Dialogue Period, shall notify Landlord thereof. 

  

	 	ii.	Prior to or at the end of the Review and Dialogue Period relative to phase 5 of the Design Materials, Tenant shall notify Landlord of any Design Failure known to Tenant relative to
the Design Materials for such phase as submitted by Landlord at the beginning of such Review and Dialogue Period, and Tenant shall be deemed to have waived any such Design Failure of which it did not so notify Landlord as required by this
Section 3.e.2. 

  

 D-2-5 

	 	iii.	No failure by Tenant to comply with this Section 3.c shall constitute a default by Tenant under this Workletter or give rise to any liability on Tenant’s part.

  

	4	Bidding. 

  

	 	a.	Promptly after the 30th day after the Participants receive the phase six Design Materials conforming to the requirements of Section 3 (such 30th day being the “Bidding
Instruction Deadline”), Landlord shall solicit bids for the Shared Facilities Work from such bidders and in accordance with such procedures, terms and conditions as Landlord shall reasonably determine. 

 Upon receipt by Landlord of any bid for any portion of the Shared Facilities Work, Landlord shall promptly furnish copies thereof to all Participants.

 Landlord shall not unreasonably reject any instructions given to it by Majority Instrument prior to the Bidding Instruction Deadline with
regard to contractors and suppliers from whom bids should be solicited and the terms and conditions of the solicitation of such bids. 
  

	 	b.	Promptly after the 30th day after the date on which Landlord has furnished to all Participants all of the bids to be received for the Shared Facilities Work and notified the
Participants that no further bids are expected (such 30th day being herein called the “Bidding Award Instruction Deadline”), Landlord, subject to Section 2.c, shall: 

  

	 	i.	make such final revisions to the Design Materials, and 

  

	 	ii.	enter into such contracts to be negotiated by Landlord for the Shared Facilities Work with such bidders, 

 as shall be determined by Majority Instrument given by the Bidding Award Instruction Deadline (or, if not so determined, as reasonably determined by
Landlord); provided, however, that unless required to satisfy the Minimum Requirement, Landlord shall not be required to comply with any instructions which would cause Landlord’s Costs relative to the Shared Facilities Work to exceed (or to
increase the amount by which it exceeds) the Reimbursable Cost Limit, unless one or more of the Participants agree to reimburse Landlord for such excess pursuant to a written instrument in form and substance reasonably satisfactory to Landlord.

  

	5	Construction. 

  

	 	a.	Subject to Section 2.c, Landlord, at its sole cost and expense (except as otherwise provided in Section 9) shall perform the Shared Facilities Work:

  

	 	i.	with diligence and continuity and (except as otherwise required by the provisions of this Workletter) in a commercially reasonable manner as if Landlord were spending only its own
money; 

  

 D-2-6 

	 	ii.	in accordance with Landlord’s Design Materials prepared and revised in accordance with the provisions of Section 3 and 4; 

  

	 	iii.	pursuant to contracts entered into in accordance with Section 4; and 

  

	 	iv.	in accordance with the requirements of this Workletter. 

  

	 	b.	Throughout such construction, Landlord, subject to Section 2.c, shall consider in good faith for adoption all of Tenant’s comments and suggestions.

  

	 	c.	Landlord shall furnish electricity and HVAC to all contractors and suppliers performing the Shared Facilities Work without charge. 

  

	 	d.	Landlord shall furnish vertical transportation and construction debris removal to all contractors and suppliers performing the Shared Facilities Work in accordance with the terms

	6	Effect and Scope of Tenant’s Approval. 

  

	 	a.	Tenant shall have no liability to Landlord or to any third party by virtue of the existence or exercise of its rights in this Workletter. Additionally, neither Tenant’s making
any comments or suggestions or joining in any Majority Instrument or Unanimous Instrument, or failing to do so, shall constitute a representation or warranty by Tenant that the Design Materials or the Shared Facilities Work (i) are complete or
suitable for their intended purpose, or (ii) comply with applicable laws, ordinances, codes and regulations, or (iii) satisfy the Minimum Requirement, it being expressly agreed by Landlord that Tenant assumes no responsibility or liability
whatsoever to Landlord or any other person or entity for such completeness, suitability, compliance or satisfaction. 

  

	 	b.	Section 6.a shall not void or limit the effect of Section 3.e.2. 

  

	7	Commencement Dates. 

  

	 	a.	As used in the Lease, the term “Cafeteria Commencement Date” shall mean the later of (A) the Rent Commencement Date, and (B) the date on which
(i) the Shared Facilities Work pertaining to the Cafeteria and the Circulation Area (except the portion thereof comprising the MB Construction Passageway) is substantially completed and a partial certificate of occupancy permitting occupancy of
the Cafeteria has been issued, and (ii) the Cafeteria shall have opened for business with substantially all of its facilities and equipment present and operating. 

  

	 	b.	 As used in the Lease, the term “Fitness Center Commencement Date” shall mean the later of (A) the Rent Commencement Date, and (B) the
date on which (i) the Shared Facilities Work pertaining to the Fitness Center and the Circulation Area (except the portion thereof comprising the MB Construction Passageway) is substantially completed 

  

 D-2-7 

	 	 
and a partial certificate of occupancy permitting occupancy of the Fitness Center has been issued, and (ii) the Fitness Center shall have opened for
business with substantially all of its facilities and equipment present and operating. 

  

	 	c.	As used in the Lease, the term “Circulation Area Commencement Date” shall mean the earlier of the Cafeteria Commencement Date or the Fitness Center Commencement
Date. 

  

	8	Tenant’s Right of Entry; Schedule Updates. 

  

	 	a.	During the construction of, and upon completion of, the Shared Facilities Work, Tenant and its design professionals and consultants shall have the right to enter the Shared
Facilities and any portion thereof in order to inspect the Shared Facilities Work provided, however, that: 

  

	 	i.	the same shall be subject to Landlord’s reasonable notice, scheduling and security requirements, and 

  

	 	ii.	Landlord shall have the right to accompany such persons during any such inspections. 

  

	 	b.	Within five (5) Business Days of Tenant’s request from time to time, Landlord shall furnish Tenant with a copy of Landlord’s most recent construction schedule, and
any expected deviations therefrom and Landlord’s then best estimate of the Cafeteria Commencement Date and the Fitness Center Commencement Date (it being understood that Landlord shall not be deemed to warrant the accuracy of such materials and
that the furnishing of such materials shall not limit or constitute a waiver of any of Landlord’s rights under this Workletter). 

  

	9	Tenant’s SF Contribution. 

  

	 	a.	Landlord shall furnish Tenant with copies of invoices and sworn statements evidencing all of Landlord’s Costs, together with such additional information as Tenant may
reasonably request. 

  

	 	b.	After Landlord has paid Landlord’s Costs equal to the Shared Facilities Allowance, Tenant shall pay Tenant’s SF Contribution to Landlord, in installments (no more
frequently than monthly), each such installment due on or prior to the 30th day following Tenant’s receipt of the material required by Section 9.a. Tenant, if it so elects, shall be permitted to pay installments of Tenant’s SF
Contribution by applying a portion of the Fit-Out Work Allowance thereto. If Tenant elects to apply a portion of the Fit-Out Work Allowance to any installment of Tenant’s SF Contribution, Tenant shall so direct Landlord in writing on or prior
to the 30th day following Tenant’s receipt of the material required by Section 9.a. 

  

 D-2-8 

	 	c.	The amount of Tenant’s SF Contribution and the Shared Facilities Allowance initially shall be calculated based on the aggregate Rentable Area of the Cafeteria Space, the
Fitness Center Space and the Circulation Area set forth in Article 7 of the Lease (the “Article 7 Area”). If the aggregate Rentable Area of the Cafeteria Space, the Fitness Center Space and the Circulation Area reflected in the
Final Measurement Repot is more or less than the Article 7 Area, the SF Contribution and the Shared Facilities Allowance shall be recalculated. If Tenant shall have theretofore made payment under Section 9.b, then, within ten (10) days of
the Final Measurement Report, Tenant shall pay Landlord any underpayment or Landlord shall refund any overpayment. 

  

	10	Standards of Performance. The Shared Facilities Work shall be done according to the standards set forth in this Section 10. 

  

	 	a.	Compliance with Laws. Landlord shall cause the Construction Documents and Shared Facilities Work to comply with all Laws applicable thereto, including, without limitation,
all applicable building and fire codes of the City of Chicago and all other governmental authorities having jurisdiction, and with all requirements of the Americans with Disabilities Act of 1990, 42 U.S.C. §§ 12-101 et seq; provided,
however, that this Section 10.a shall not excuse or release Landlord from its obligation to satisfy the Minimum Requirement. 

  

	 	b.	Certificate of Occupancy. Upon completion of the Shared Facilities Work, Landlord, at its own cost and expense, shall apply for and use commercially reasonable efforts to
obtain a certificate of occupancy for the Shared Facilities. 

  

	 	c.	Quality of Construction. Landlord shall use only new, first class materials in the Shared Facilities Work. Landlord shall cause all Shared Facilities Work to be done in a
good and workmanlike manner. 

  

	11	Representatives; Meetings. 

  

	 	a.	Appointment of Representatives. Each of Landlord and Tenant shall appoint one or more individual representatives (“Representatives”) who are authorized to

dispute resolution procedure shall be a multi-tiered/multi-level review process. Each tier shall consist of a “Dispute Resolution Team” composed of the individuals identified below and, at such party’s option, their legal
counsel. 

  

	 	b.	Section 27.b of the Regular Workletter is hereby incorporated herein by reference. 

  

	 	c.	Section 27.c of the Regular Workletter is hereby incorporated by reference.

	XII.	PROTECTION SYSTEMS 

  

	 	A.	A design response to potential explosive threats will be incorporated, including hardening of building elements to isolate explosive threats from the occupied spaces, reduce glass
fragment hazard within floors 4 through 9 and mitigate the potential for progressive collapse of the structure. Isolation of the occupants from the internal explosive threats will be achieved through adequate strength and ductile detailing of
hardened slabs and walls. The reduction of glass fragment hazards to a medium level of protection will be achieved through the use of protective glazing materials and the appropriately sized mullions and anchorages. The protection against
progressive collapse will be achieved by means of the specific local resistance method in which critical load bearing elements are designed to resist failure in response to the specified threats. 

  

	 	B.	The structure will be designed to resist a 500-pound TNT explosive vehicle threat located on the surrounding streets or within Lower Wacker Drive. This design will be based on
standoff distances associated with a perimeter protection that will prevent the 500-pound TNT explosive vehicle threat from approaching the face of the building or entering the loading dock. Standoff protection at the ground floor will include steel
bollards on the Wacker, Monroe and Franklin exposures and stone-clad reinforced concrete planters at Wacker/Monroe and Monroe/Franklin corners. 

  

 H-1-13 

	 	C.	The Goldman Sachs façade will be designed with a laminated thermally tempered glass that is retained within the curtain wall frames with a structural silicone adhesive. The
glass, the frames and the anchorage will be designed to ensure all components of the system are capable of developing their maximum capacity and that the capacity of the anchorage exceeds the capacity of the frames which exceeds the capacity of the
glass. This balanced glazing system will provide a medium level of protection (low hazard or better) to the majority of the occupants in response to blast overpressure. 

  

	 	D.	The glazing enclosing the lobby will be laminated designed to limit the extent of debris and hazard to occupants. 

  

	 	E.	The punched windows in the hardened wall facing the alley will provide a level of protection consistent with the windows on the remaining sides of the building. However, due to the
short standoff distances and confinement of the blast pressures, the effectiveness of the punched window glazing at lower elevations will be limited to smaller explosive threats. 

  

	 	F.	The building structure will be designed to resist the effects of a 50-pound TNT explosive satchel threat exterior to the building, within the lobby (exterior to the security
screening station) and within the loading dock. However, in lieu of an alternate path design, in which the structure is capable of sustaining the loss of any single column exposed to an explosive threat, the columns within the loading dock will be
designed to sustain the design level explosive threat to which it may be exposed. 

  

	 	G.	The hardened walls at Floor B2 are required to isolate the critical mechanical equipment from the effects of a blast originating within sub-level 2 parking garage. The column and
concrete core upgrades at this level are required to prevent the loss of a primary load-bearing element that could precipitate a progressive collapse. 

  

	 	H.	The hardened walls at Floor 1 are required to protect the lobby from the effects of blast originating within Floor 1 parking garage, the retail spaces and the exterior explosive
threats. The parking garage wall abutting the alley shall not be hardened construction to allow venting of gas pressures to the exterior of the building. Floor 1 floor slab hardening protects the lobby from an explosion within the below grade
parking garage and loading dock. Floor 1 floor hardened slab also protects below grade mechanical spaces from an explosion within Level 1 parking garage and retail spaces. The column and concrete core upgrades at this level are required to prevent
the loss of a primary load-bearing element that could precipitate a progressive collapse. The hardened floor beams protect the structural frame from an explosion originating below grade or at Floor 1. The lobby glazing shall be laminated
glass to limit the debris, but will not be designed to resist an exterior explosive device. 

  

 H-1-14 

	 	I.	The hardened walls at the Mezzanine Level are required to protect the occupied spaces (kitchen, servery, cafeteria, etc.) from an explosion in the alley, within the lobby or
surrounding streets. The curtain wall façade and punched windows mitigate the hazard of airborne debris resulting from an exterior explosive device. Mezzanine Level will have hardened floor slabs to protect the occupied spaces from an
explosion in Level 1 parking and retail spaces. The perimeter column and concrete core upgrades at this level are required to prevent the loss of a primary load-bearing element that could precipitate a progressive collapse. The hardened floor beams
protect the structural frame from an explosion at Level 1. 

  

	 	J.	The hardened walls at Floor 4 are required to protect the mechanical equipment from an explosion in the alley or surrounding streets. The curtain wall facade, punched windows and
skylights mitigate the hazard of airborne debris resulting from an exterior explosive device. The bustle mechanical floor slabs will protect the occupied spaces from an explosion in the lobby and the exterior explosive device.

  

	 	K.	The hardened walls at Floors 5 through 7 are required to protect the occupied spaces from an explosion in the alley or surrounding streets. The curtain wall façade and
punched windows mitigate the hazard of airborne debris resulting from an exterior explosive device. 

  

	 	L.	The curtain wall façade at Floor 8 mitigates the hazard of airborne debris resulting from an exterior explosive device. The hardened roof slab protects the occupied space in
Floor 7 below from an exterior explosive device.

 WHEREAS, Landlord and Tenant have heretofore entered into a certain lease dated ______________ _____, 2002 (such lease, together
with all exhibits attached thereto including, without limitation, the Workletter, the Shared Facilities Workletter and the Terms of Parking License, being hereinafter referred to as the “Original Lease”), demising
certain premises in the building known as 71 South Wacker Drive, Chicago, Illinois; 
 [WHEREAS, Landlord and Tenant have heretofore
entered into [describe any amendments and modification]]; 
 WHEREAS, the Original Lease has not been amended or modified [except as
described above]; 
 WHEREAS, as used herein the term “Lease” shall refer to the Original Lease, together with
[the amendments and modifications described above and] such amendments and modifications as may hereafter be entered into, excluding any such amendments and modifications hereafter entered into requiring Lender’s consent under Section 9
below, unless Lender shall have consented thereto; 
 WHEREAS, concurrently herewith Lender is making a mortgage loan to Landlord (the

renewals thereof, the “Note”) of even date herewith executed by Landlord and payable to Lender, and secured in part by (i) a Mortgage (including any consolidations, extensions, modifications or renewals thereof, the
“Mortgage”) of even date herewith covering the Land and Building (as defined in the Lease) in which the Premises (as defined in the Lease) are located, which Land is legally described on Exhibit “A” attached hereto
and (ii) an assignment of Landlord’s interest in the Lease of even date herewith (including any consolidations, extensions, modifications or renewals thereof, the “Assignment of Lease”); and 
 WHEREAS, Landlord and Tenant jointly and severally acknowledge the Assignment of Lease; and 
  

 L-1-1 

 WHEREAS, the parties hereto desire to establish additional rights of quiet and peaceful possession
for the benefit of Tenant, and further to define the covenants, terms, and conditions precedent to such additional rights. 
 NOW,
THEREFORE, in consideration of the covenants, terms, conditions, agreements, and demises herein contained, and in consideration of other good and valuable consideration, each to the other, the sufficiency and receipt of which are hereby
acknowledged, the parties hereto agree, covenant, and warrant as follows: 
 1. Capitalized terms used but not defined herein are used herein
as defined in the Lease. 
 2. Subject to the terms and conditions of this Agreement, the Lease is and shall be subject and subordinate in
all respects to the Mortgage and the lien created thereby and to any advancements made thereunder. 
 3. So long as no monetary or material
non-monetary Default has occurred and is continuing under the Lease, Lender hereby covenants and agrees that if Lender or any other person (Lender or such other person being herein called a “Successor”) obtains Landlord’s interest in
the Property by judicial or power of sale foreclosure of the Mortgage or by reason of any other enforcement of Lender’s rights under the Mortgage or by deed in lieu of foreclosure (a “Succession Event”), then: 
  

	 	(a)	Successor shall succeed to Landlord’s interest in the Lease and shall recognize the Lease, and the Lease shall continue in full force and effect with direct privity of estate
and contract between Successor and Tenant with the same force and effect and relative priority in time and right as though the Lease had been originally made directly between Successor and Tenant; and 

  

	 	(b)	Tenant’s rights under the Lease, including its occupancy of the Premises, its use of the Shared Facilities, and its use of any parking spaces licensed to Tenant pursuant to the
Lease, shall not be disturbed. 

 4. Tenant shall give to Lender a copy of any Qualified Notice (as herein defined) given by
Tenant to Landlord and no such Qualified Notice shall be effective unless and until Tenant shall have given such a copy to Lender. The term “Qualified Notice” shall mean (i) any notice of default under the Lease by Landlord given by
Tenant to Landlord, (ii) any notice of termination of the Lease given by Tenant to Landlord under Paragraphs 4(E), 4(F) or 10(A)(ii) of the Lease or under any other provision of the Lease expressly affording Tenant the right to terminate the
Lease, and (iii) any notice under Paragraph 24(B) of the Lease given by Tenant to Landlord. 
 5. If any act or omission of Landlord
would give Tenant the right, immediately or after lapse of a period of time, to cancel or terminate the Lease (other than pursuant to a right of cancellation or termination expressly set forth in the Lease) or to abate or offset against payment of
Rent (other than a right of abatement or offset expressly set forth in the Lease) or to claim a partial or total eviction, Tenant shall not be entitled to exercise such right, unless such act or omission shall have continued unremedied for thirty
(30) days after written notice thereof is given to Landlord and Lender; provided that, if more than thirty (30) days are reasonably 

  

 L-1-2 

 
required to effect such remedy and Landlord or Lender commences to remedy such act or omission within thirty (30) days after receipt of Tenant’s
notice thereof, then such period shall be extended so long as Landlord or Lender is diligently prosecuting such remedy to completion. The aforementioned periods of time permitted for Landlord or Lender to cure shall be extended for any period of
time during which Landlord or Lender is delayed in, or prevented from, curing due to Unavoidable Delays. 
 6. If the interests of Landlord
under the Lease shall be transferred to a Successor by reason of a Succession Event prior to the expiration or earlier termination of the Lease, then Tenant hereby covenants and agrees to make full and complete attornment to the Successor as
substitute landlord upon the same terms, covenants and conditions as provided in the Lease (subject to Section 3 above and Section 9 below) so as to establish direct privity of estate and contract between the Successor and Tenant with the
same force and effect and relative priority in time and right as though the Lease had been originally made directly between Successor and Tenant; except, that (subject to Section 16 below) Tenant shall be under no obligation to pay rent to the
Successor until Tenant receives written notice from Lender that a Succession Event has occurred. Tenant will thereafter make all rent payments due under the Lease directly to Successor, as the substitute landlord thereunder and Landlord hereby

at law by Lender to gain possession of the Landlord’s interest in the Premises or Property. Unless required by law Lender shall not name Tenant in any such action and if Tenant is required to be so named then none of Tenant’s rights under
the Lease or this Agreement shall be affected in such action. Lender, simultaneously with giving any notice of default under the Note, Mortgage or Assignment of Lease or any other instrument evidencing or securing the Loan (together, the “Loan
Documents”) or commencing any foreclosure, shall furnish to Tenant a copy of such notice or of the documents commencing such foreclosure; but Lender’s failure to do so shall not impair the validity of Lender’s notice or foreclosure or
the terms of this Agreement. 
 8. The provisions of this Agreement shall be real covenants running with the Land, and shall be binding upon
and inure to the benefit of the respective parties hereto and their respective heirs, executors, administrators, beneficiaries, successors and assigns, including without limitation any person who shall obtain, directly or by assignment or
conveyance, (a) any interest in the Mortgage; (b) any certificate or deed of purchase following foreclosure of the Mortgage; (c) any certificate of redemption following such foreclosure; or (d) title to the Property through a
Succession Event.

 Ladies & Gentlemen: 
 FRANKMON LLC (“Landlord”), the landlord under that certain Office Lease dated as of September __,

terms and conditions, hereby grants its consent to the assignment by Tenant to ________, a __________ (“New Owner”) of all of Tenant’s right, title and interest in, to and under the Lease. 
 The capitalized terms used herein and not otherwise defined shall have the meanings ascribed thereto in the Lease. This letter (this “Consent and

 As a condition to the consent of Landlord, it is understood and agreed as follows: 
  

	1.	This Consent and Agreement shall in no way release Tenant or any person or entity claiming by, through or under Tenant (including New Owner) from any of their respective covenants,
agreements, liabilities and duties under the Lease, as the same may hereafter be amended or modified; provided, however, that Tenant shall not be liable for any increased or additional obligations arising out of any amendment or modification of the
Lease hereafter entered into, except for such increased or additional obligations as arise out of any such amendment or modification that effects the exercise by New Owner of any right of the tenant under Paragraphs 35(F) or 35(G) of the Lease as

 HYATT CORPORATION

 Attention: Geoffrey Rockhill — Corporate Services 
  

	 	Re:	71 South Wacker, Chicago — Consent to Sublease 

 Ladies & Gentlemen: 
 FRANKMON LLC (“Landlord”), the landlord under that certain Office Lease dated as of
________________, as amended and modified by ________________________ dated ________________ (as so amended and modified and as hereafter amended and modified from time to time, the “Lease”), by and between Landlord, as landlord and
HYATT CORPORATION, as tenant (“Tenant”), subject to and specifically conditioned upon the following terms and conditions, hereby grants its consent to the subleasing by Tenant to [insert name and entity type of Transferee (as such
term is defined in the Lease)], as sublessee (“Sublessee”) of all or any portion or portions of [insert description of Subject Space (as such term is defined in the Lease) including all expansion rights and options described in
Tenant’s request for consent] (the “Subleased Premises”) in the Building commonly known as 71 South Wacker Drive, or Hyatt Center, Chicago, Illinois (the “Building”) for term or terms expiring no later than
[insert final expiration date described in Tenant’s request for consent, including all renewal rights and options described in Tenant’s request for consent] (the “Sublease Expiration Date”). 
 The capitalized terms used herein and not otherwise defined shall have the meanings ascribed thereto in the Lease. This letter (herein this “Consent and
Agreement”) and the acknowledgment and the acceptance of the conditions hereof may be executed in counterparts, each of which shall be considered an original but constituting one and the same document. 
 As a condition to the consent of Landlord, it is understood and agreed as follows: 
 The sublease agreement between Tenant and Sublessee, as the same may be amended, modified or supplemented from time to time, is herein called the “Sublease”. Landlord is not consenting to and shall not be bound by any of the terms
or provisions of the Sublease. The Sublease is solely for the purpose of setting forth the rights and obligations between Tenant and Sublessee and shall not bind 

 
Landlord. Tenant shall furnish Landlord with a fully-executed counterpart of the Sublease as originally entered into no later than Sublessee’s entry
into the Subleased Premises, and shall furnish Landlord with a fully-executed counterpart of any amendment, modification or supplement thereto immediately upon the execution and delivery thereof. This Consent and Agreement shall not apply to any
amendment, modification or supplement covering any premises outside of the Subleased Premises or any period after the Sublease Expiration Date, and any such amendment, modification or supplement shall be regarded as a new sublease subject to
Landlord’s consent as provided for in the Lease. 
  

	 	1.	This Consent and Agreement shall in no way release Tenant or any person claiming by, through or under Tenant from any of its covenants, agreements, liabilities and duties under the
Lease, as the same may hereafter be amended or modified. 

  

	 	2.	This Consent and Agreement shall not be construed to amend or modify the Lease in any respect, nor shall this Consent and Agreement constitute Landlord’s consent to any
Alterations. 

  

	 	3.	Tenant shall be liable to Landlord for any default under the Lease, whether such default is caused by Tenant or Sublessee or anyone claiming by or through either Tenant or
Sublessee, but the foregoing shall not be deemed to restrict or diminish any right which Landlord may have against Sublessee pursuant to the Lease, in law or in equity, for violation of the Lease or otherwise, including, without limitation, the
right to enjoin or otherwise restrain any violation of the Lease by Sublessee. 

  

	 	4.	The Sublease is, in all respects, subject and subordinate to the Lease. Furthermore, in the case of any conflict between the provisions of this Consent and Agreement or the Lease
and the provisions of the Sublease as such relate to Landlord, the provisions of this Consent and Agreement or the Lease, as the case may be, shall prevail unaffected by the Sublease. 

 If at any time prior to the expiration of the term of the Sublease, the Lease shall terminate or be terminated for any reason (or Tenant’s right to
possession shall terminate without termination of the Lease), the Sublease shall simultaneously terminate. [To be inserted at Landlord’s election: However, Sublessee agrees that, at the election and upon written demand of Landlord and not
otherwise, the Sublease shall continue with the same force and effect as if Landlord and Sublessee had entered into a lease as of the effective date of such termination for a term equal to the then unexpired term of the Sublease and containing the
same provisions as those contained in the Sublease. In such a case, and not otherwise, Sublessee shall attorn to Landlord and Landlord shall recognize Sublessee and Landlord and Sublessee shall have the same rights, obligations and remedies as
Tenant and Sublessee had prior to such effective date, except that in no event shall Landlord be 
  

	 	(i)	liable for any act or omission by Tenant, or 

	 	(ii)	subject to any offsets or defenses not provided for in the Sublease, or 

  

	 	(iii)	bound by any rent or additional rent or other payment paid by Sublessee to Tenant more than thirty (30) days in advance of its due date which was not actually received by
Landlord, or 

  

	 	(iv)	bound by any amendment, modification or supplement to the Sublease which Landlord had not received prior to such effective date or (unless Landlord shall have consented thereto)
which required Landlord’s consent as provided for in Paragraph 1 above. 

 The foregoing provisions of this Paragraph shall apply
notwithstanding that as a matter of law, the Sublease may otherwise terminate upon termination of the Lease, and shall be self-operative following Landlord’s written election to continue the Sublease as aforesaid and no further instruments
shall be required to give effect to said provisions. Upon such written election by Landlord to continue the Sublease as aforesaid, however, Landlord and Sublessee shall execute, from time to time, documents in confirmation of the foregoing
provisions of this Paragraph reasonably satisfactory to the parties, acknowledging such attornment and recognition and setting forth the terms and conditions of Sublessee’s tenancy.] Nothing contained in this Paragraph shall be construed to
impair or modify any right otherwise exercisable by Landlord, whether under the Lease, any other agreement or in law. 
  

	 	5.	Nothing herein contained shall be deemed a waiver of any of the Landlord’s rights under the Lease. [To be inserted at Landlord’s election: Except as provided in
Paragraph 7 above following Landlord’s exercise of its election to continue the Sublease,] in no event shall Landlord be deemed to be in privity of contract with Sublessee or owe any obligation or duty to Sublessee under the Lease or
otherwise, any duties of Landlord under the Lease being in favor of, for the benefit of and enforceable solely by Tenant. 

  

	 	6.	Sublessee shall maintain property and liability insurance as required by Article 11 of the Lease (except that Sublessee shall not be required to insure any property insured by
Tenant) and shall cause the Landlord Protected Parties to be named as additional insureds on such liability insurance. Prior to its entry into the Subleased Premises and prior to each policy expiration, Sublessee shall furnish Landlord with
certificates of such insurance which certificates shall confirm that the Landlord Protected Parties have been so named on the liability insurance. The provisions of Paragraph 11(H) and Paragraphs 26(A) through (E) of the Lease shall apply
directly between Landlord and Sublessee as if the same were set forth herein and referred to Sublessee rather than Tenant. 

  

	 	7.	This Consent and Agreement shall be deemed limited solely to the Sublease, and nothing herein shall be deemed Landlord’s consent to any further or additional sublease by Tenant
or Sublessee or any assignment or transfer of the Lease or the Sublease. 

	 	8.	Landlord, Tenant and Sublessee hereby confirm the provisions of Paragraph 21(D) of the Lease. 

 This Consent and Agreement shall not be effective, and Sublessee shall not enter into possession of the Subleased Premises, unless and until Landlord shall receive a copy of this Consent and Agreement executed by
Tenant and Sublessee as provided below. If Landlord shall not have received a copy of this Consent and Agreement executed by Tenant and the Sublessee within 90 days of the date hereof, this Consent and Agreement shall be void.

 As used in this document (this “License”),
(i) the term “Building” shall refer to 71 South Wacker Drive, Chicago, Illinois, (ii) the term “Lease” shall mean the lease to which this document is attached, (iii) the term “Licensor” shall refer to the
Landlord under the Lease and (iv) the term “Licensee” shall refer to the Tenant under the Lease. 
 This License sets forth
the terms and conditions applicable to the parking spaces in the Building’s parking garage licensed by Licensor to Licensee (the “Parking Spaces”). 
  

	1.	Licensee shall pay to Licensor or Licensor’s agent in the office of the Building, or at such other place as Licensor may from time to time designate in writing, a monthly fee
for each Parking Space at the rate established by Licensor from time to time in accordance with the Lease (the “Fee”). The Fee shall be payable on or before the first day of each month in advance. Licensor shall give Licensee not less than
forty-five (45) days’ prior written notice of any change in the Fee. 

  

	2.	This License will terminate upon the expiration or earlier termination of the Lease. Upon the termination of this License Licensee agrees to surrender possession of the Parking
Spaces immediately (without receipt of demand for fees, notice to quit or demand for possession), and Licensee hereby grants to Licensor the right, with or without process of law, to expel Licensee from the Parking Spaces, and Licensor may use such
force in expelling Licensor as may be reasonably necessary, and Licensor may repossess itself of the Parking Spaces, but said entry shall not constitute a trespass or forcible entry or detainer, nor shall it cause a forfeiture of fees due by virtue
thereof. Licensee waives all notice of any election made by Licensor hereunder, demand for fees, notice to quit, demand for possession and all notice and demand whatsoever. If the number of Parking Spaces licensed to Licensee shall be reduced or if
Licensor shall designate different Parking Spaces for Licensee, the provision of this Section 2 shall be applicable to the Parking Spaces to be given up by Licensee. 

  

	3.	The Fee does not include parking taxes or similar fees or assessments relating to Licensee’s use of the Building for parking, which may be imposed by any applicable taxing
authority, including, without limitation any state, municipal or federal agency or other regulatory body. Licensee shall be responsible for the payment of all such taxes, fees and similar assessments now or hereafter imposed upon Licensor or
Licensee in connection with Licensee’s use of the Building for parking in accordance with the License. 

	4.	Use of the Parking Spaces shall be limited to employees of Licensee or of any other occupant of the premises demised by the Lease (including subtenants) and their respective
vehicles, and such employees and vehicles shall be designated by Licensee to Licensor from time to time. Licensee may change such designations at any time upon notice to Licensor or its parking operator in accordance with such procedures as Licensor
may reasonably adopt. Such procedures shall include reasonable provision for temporary or “loaner” vehicles. Licensee shall not permit any person or vehicle other than those designated as provided for above to use the Parking Spaces.

  

	5.	No more than one (1) vehicle per Parking Space shall be parked or stored at any one time. 

  

	6.	Licensee shall obey and cause its employees to obey the Parking Rules and Regulations attached hereto and such reasonable amendments and modifications thereto as Landlord shall from
time to time promulgate, including with respect to implementation of the arrangements described in Section 16 below. Licensor shall make reasonable efforts to have others comply with the Parking Rules and Regulations. 

 

	7.	This License is for self-service parking only and does not include the right to any additional services, which services may be made available by Licensor from time to time at an
additional charge. 

  

	8.	Licensor and its agents and employees shall not be liable for loss or damage to any vehicle within the Parking Spaces or the garage and/or to the contents of any such vehicle caused
by fire, theft, explosion, freezing of circulation system of any vehicle, strikes, vandalism, riots or by any other acts of God and Licensee waives any claim against Licensor and its employees and agents for and in respect thereto.

  

	9.	The relationship between Licensor and Licensee constitutes only a license to use the Parking Spaces and the garage. Neither this License nor the parking of any vehicle shall
constitute or give rise to a bailment or create the relationship of bailor and bailee. 

  

	10.	Except for notices under Section 4 (which may be given by any reasonable manner), all notice hereunder shall be given in accordance with the Lease. 

  

	11.	In the event the garage or Building shall be damaged by fire or other casualty, the Fee shall be abated with respect to any Parking Space rendered unusable until it again becomes
usable. 

  

	12.	If all or any part of the garage is taken by eminent domain proceedings, Licensor shall be entitled to all of the award in the proceedings. If the entire garage is taken, this
License shall terminate. In the event of a partial taking, Licensor may reduce the number of Parking Spaces in proportion to the extent of such partial taking upon written notice to Licensee. 

	13.	This License shall be subject and subordinate to any mortgage or ground lease to which the Lease is subject and subordinate and shall be entitled to the benefit of any
subordination, non-disturbance and attornment agreement to which the tenant under the Lease is a party. 

  

	14.	Licensee covenants not to cause any waste or damage or disfigurement or injury to the garage. Licensee agrees that if, in the Licensor’s reasonable judgment, Licensee’s
vehicle(s) shall become a hazard or nuisance to person(s), other vehicles, the garage or the Building while parked in the garage, Licensee’s vehicle(s) shall be removed from said garage by Licensor’s personnel, or its agents, and any
charges or costs incurred in the removal shall be borne by Licensee.

time in an emergency, to make repairs and maintenance, to prevent a taking by adverse possession or prescription or to comply with any governmental order or directive. Where practicable Licensor shall give and post notice of such closure at least
one (1) business day in advance. All the aforesaid acts may be done by Licensor without being liable to others by reason of inability to use the garage, except that the Fee shall abate in case of any closure or denial of access extending for
more than one (1) business day. 

  

	16.	Any licensee of a Parking Space in the Arcade Place garage arriving at the Building when the Arcade Place garage is closed to vehicular access as provided for above shall have the
right to enter the Lower Wacker Drive garage and park in any empty space in the Lower Wacker Drive garage, provided such licensee removes its vehicle from such space no later than when the Arcade Place garage next opens for vehicular access. Any
licensee of a Parking Space in the Lower Wacker Drive garage whose Parking Space is occupied by a vehicle parked pursuant to the preceding sentence shall have the right to park in any other space in the Lower Wacker Drive garage, provided such
licensee removes its vehicle from such other space no later than when the Arcade Place garage next opens for vehicular access.

Wacker Drive garage shall be specifically reserved dedicated spaces. 

	18.	Licensee shall, when using the parking facilities of said garage, observe and obey all signs regarding fire lanes and no parking zones, and when parking always park between
designated lines. Licensor reserves the right, without notice, to tow away, or otherwise impound, at the expense of the owner or operator, any vehicle which is improperly parked or parked in a fire lane or a no parking zone or any vehicle in
violation of Section 16; provided, however, that in the case of any such violation of Section 16 by Licensee or any of its employees, Licensee shall also be responsible for such expense. 

  

	19.	In the event a key or other access device is supplied by Licensor to Licensee in connection with the rights granted herein, Licensee will surrender such key or access device to
Licensor upon termination of this License. Licensee agrees at all times, to display a proper identification card, windshield sticker or other identification as Licensor may from time to time require.

Parking Spaces. This License may not be recorded in any governmental recording office.

shall have not subleased more than 25% of the Premises for all or substantially all of the remaining Term (excluding subleases pursuant to Paragraph 21(C)), and (iii) this Lease shall then be in full force and effect, then Tenant shall
have the one-time option (the “Second Expansion Option”) to expand the Premises to include the Second Expansion Premises upon the following terms and conditions: 
 (i) If Paragraph 35(A)(iv) and clause (d) thereof is applicable or if Paragraph 35(A)(vi) and clause (d) thereof is applicable,
then, in either such case, the Second Expansion Option shall be void and of no force or effect. 
 (ii) The term
“Second Expansion Option Scheduled Delivery Date” shall mean the sixth anniversary of the Rent Commencement Date; provided, however, that Landlord shall have the right, by notice to Tenant given no later than the Second Expansion
Option Rescheduling Deadline Date, to designate as the Second Expansion Option Scheduled Delivery Date any earlier date no earlier than the fifth anniversary of the Rent Commencement Date. Any such notice by Landlord shall be irrevocable, and shall
relate to the entire Second Expansion Premises. 
 (iii) The term “Second Expansion Option Rescheduling Deadline
Date” shall mean the 30th day after Landlord’s receipt of the Second Expansion Notice; provided, however, that Tenant shall have the right, by notice to Landlord (the “Rescheduling Deadline Date Acceleration Notice”),
given no earlier than 30 days before the third anniversary of the Rent Commencement Date, to accelerate the Second Expansion Option Rescheduling Deadline Date to the 30th day after the date of the Rescheduling Deadline Date Acceleration Notice.

 (iv) The term “Second Expansion Option Exercise Deadline Date” shall mean (a) if
Tenant shall have given the Rescheduling Deadline Date Acceleration Notice, the 547th day before the Second Expansion Option Scheduled Delivery Date, or (b) otherwise, the 547th day before the fifth anniversary of the Rent Commencement Date. 
  

 4 

 (v) Tenant shall exercise the Second Expansion Option, if at all, by delivery to Landlord
of a written notice of exercise (the “Second Expansion Notice”) on or before the Second Expansion Option Exercise Deadline Date. If Tenant fails to deliver the Expansion Notice by such date, Tenant shall be deemed to have
waived its Second Expansion Option. If Paragraph 35(A)(v) and clause (c)(i) thereof is applicable, then 
  

	 	(1)	Tenant shall specify in such Second Expansion Notice whether the Second Expansion Premises shall be (X) the South Eighth Floor Premises, (Y) the Ninth Floor Premises, or
(Z) both, and 

  

	 	(2)	if Tenant fails to so specify the Second Expansion Premises, the Second Expansion Premises shall be deemed to be both (i.e., as provided for in clause (Z)); and

  

	 	(3)	if Tenant specifies as the Second Expansion Premises only the Ninth Floor Premises (i.e., as provided for in clause (Y)), then 

  

	 	(i)	Landlord shall have the right (the “Ninth Floor Division Right”), by notice to Tenant given within thirty (30) days of its receipt of the Second Expansion
Notice, to substitute as the Second Expansion Premises the South Eighth Floor Premises and the North Ninth Floor Premises, and 

  

	 	(ii)	 if Landlord shall exercise the Ninth Floor Division Right then, on or before the Second Expansion Option Rent Commencement Date, Landlord shall construct and finish
in accordance with Building standards all corridors, elevator lobbies and other common areas on the 9th floor required for the same to be occupied as a multi-tenant floor (the “9th Floor Division Work”). 

 (vi) If Tenant timely exercises the Second Expansion Option, then (i) on the Second Expansion Option Scheduled Delivery Date, Landlord shall deliver the Second Expansion Premises to Tenant with all Base Building
Work therein complete and otherwise in “as-is” condition, and (ii) the Second Expansion Premises shall be included in the Premises upon the same terms, covenants and conditions as are applicable to the Primary Office Premises, except
to the extent, if any, otherwise provided below: 
  

	 	(1)	the term of the letting of the Second Expansion Premises shall expire on the Initial Expiration Date, subject to extension of the Term pursuant to Paragraphs 35(F) and 35(G);

  

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses, with respect to the Second Expansion Premises, shall commence to be payable on the date (the “Second
Expansion Option Rent Commencement Date”) which is the earlier of 

  

 5 

	 	(i)	the date which is one hundred twenty (120) days after the later of (x) the date on which Landlord actually tenders possession of the Second Expansion Premises to Tenant in
the condition required by this Paragraph 35(C)(v), and (y) the Second Expansion Option Scheduled Delivery Date, and 

  

	 	(ii)	the date Tenant commences to conduct ordinary business in the Second Expansion Premises; 

 provided, however, that (a) the Rent Commencement Date shall be determined separately with respect to any portion of the Second
Expansion Premises that has been previously leased to Tenant for a term expiring immediately prior to the Second Expansion Option Scheduled Delivery Date and, with respect to such portion, the aforesaid period of 120 days shall be disregarded, and
(b) if Landlord shall have exercised the Ninth Floor Division Right, then the Second Expansion Option Rent Commencement Date shall not be deemed to occur prior to the substantial completion of the 9th Floor Division Work; 
  

	 	(3)	The amount of Net Rent per square foot of Rentable Area with respect to the Second Expansion Premises shall be equal to that applicable to the Primary Office Premises, as such Net
Rent increases from time to time as set forth in Exhibit B-1. 

  

	 	(4)	The Rentable Area of the Premises shall be increased by the Rentable Area of the Second Expansion Premises; 

  

	 	(5)	Tenant’s Pro Rata Share shall be increased to reflect the Rentable Area of the Second Expansion Premises, effective as of the Second Expansion Option Rent Commencement Date;
and 

  

	 	(6)	Landlord shall pay to Tenant an allowance (the “Second Expansion Option Allowance”) in an amount equal to $40.00 per square foot of Rentable Area in the Second
Expansion Premises. The Second Expansion Option Allowance shall be used and disbursed in accordance with the provisions and procedures set forth in the Workletter (and Paragraph 24(C)); provided, however, that Tenant shall have the right to
apply all or any portion of the Second Expansion Option Allowance as a credit against the Rent hereunder. 

 Following exercise
by Tenant of the Second Expansion Option, and within thirty (30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the
Second Expansion Premises pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or refusal of either party to do so, however, shall not affect the validity of the leasing of the Second Expansion Premises.

  

 6 

 (vii) So long as Landlord has not granted any person rights which conflict with
Tenant’s Second Expansion Option, Landlord shall have no liability to Tenant, and Landlord shall not be deemed to be in default under this Lease, if it is unable to deliver the Second Expansion Premises to Tenant on the Second Expansion Option
Scheduled Delivery Date due solely to the failure of any tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver possession of the Second Expansion Premises in the condition required by
Paragraph 35(D)(v) by the date which is the 90th day after the Second Expansion Option Scheduled Delivery Date, Tenant shall have the option either, at it elects (a) by notice to Landlord given at any time prior to the delivery to
Tenant of the Second Expansion Premises in the condition required by Paragraph 35(D)(v), to rescind its previous exercise of the Second Expansion Option, in which event Landlord shall have no liability to Tenant on account of such failure
timely to deliver (except that Landlord shall not be released from such liability if it shall have granted any person rights which conflict with Tenant’s Second Expansion Option) and shall have no further obligation to deliver the Second
Expansion Premises, or (b) to lease from Landlord on a temporary basis and at the same rent other space in the Building, to the extent available, comparable in size to the Second Expansion Premises. Landlord will use commercially reasonable
efforts to regain possession of the Second Expansion Premises as promptly as reasonably possible, including the prosecution of litigation against any occupant of such space. 
 (E) Tenant’s Right of First Offer. 
 (i) If (i) Tenant shall not have assigned this Lease (other than pursuant to Paragraph 21(C)), (ii) Tenant shall not have subleased more than 25% of the Premises for all or substantially all of the
remaining term (excluding subleases pursuant to Paragraph 21(C)), (iii) neither Tenant’s First Renewal Option nor Tenant’s Second Renewal Option shall have lapsed without exercise, and (iv) neither this Lease nor
Tenant’s right of possession of the Premises shall have been terminated and this Lease shall then be in full force and effect, then Landlord shall not lease any space on or below the 23rd floor of the Building (including by way of renewal,
extension or expansion) to any person other than: 
  

	 	(1)	(a) the initial lease of such space; and (b) except with respect to any or all Senior ROFO Space, any renewal or extension of the initial lease of such space effected
pursuant to the exercise of a renewal or extension right or option provided for in such initial lease as originally entered into (it being understood that with respect to any or all Senior ROFO Space any such renewal or extension right or option
shall be subordinate to Tenant’s rights under this Paragraph 35(E)); 

  

 7 

	 	(2)	(a) any lease of such space effected pursuant to Paragraph 35(E)(vi); and (b) except with respect to any or all Senior ROFO Space, any renewal or extension of such
lease of such space effected pursuant to the exercise of a renewal or extension right or option provided for in such lease as originally entered into (it being understood that with respect to any or all Senior ROFO Space any such renewal or
extension right or option shall be subordinate to Tenant’s rights under this Paragraph 35(E)); 

  

	 	(3)	any Permitted Expansion of any lease entered into pursuant to subparagraphs 1 or 2 above; 

  

	 	(4)	except with respect to any or all Senior ROFO Space, any lease of such space effected pursuant to the exercise by the tenant thereunder of any expansion right or option (which
phrase, as used in this Paragraph 35(E), shall include any firm option, right of refusal or right of offer) set forth in the Hyatt Lease or in the Mayer Brown Lease (“Permitted Superior Expansion Rights”) (it being
understood that (1) with respect to any or all Senior ROFO Space any such expansion right or option shall be subordinate to Tenant’s rights under this Paragraph 35(E) and (2) except for the Permitted Superior Expansion
Rights and the Permitted Expansions referred to in Paragraph 35(E)(i)(3) above, all expansion rights and options now or hereafter granted to any person shall be subordinate to Tenant’s rights under this Paragraph 35(E));

  

	 	(5)	(a) any lease for a term commencing after the 22nd anniversary of the Rent Commencement Date; or (b) any lease entered into after the lapse without exercise of the First
Renewal Option or after the lapse without exercise of the Second Renewal Option; 

  

	 	(6)	any lease of the Fitness Center or the Cafeteria to any operator, licensee or concessionaire thereof; 

  

	 	(7)	any lease on the ground floor lobby level of the Building; and 

  

	 	(8)	any lease of premises to Tenant. 

 Landlord represents and
warrants to Tenant that attached hereto as Exhibit PSER is a true and complete copy of provisions of the Mayer Brown Lease and the Hyatt Lease containing the Permitted Superior Expansion Rights, excluding the portion of such provisions
setting forth the rent payable thereunder. For all purposes of this Lease, if, pursuant to Paragraph 35(F) or Paragraph 35(G), Tenant shall rescind the exercise of the First Renewal Option or the Second Renewal Option, then the First Renewal
Option or the Second Renewal Option, as the case may be, shall be deemed to have lapsed without exercise. 
  

 8 

 The term “Permitted Expansion” means the leasing by any tenant of the Building of
additional space in the Building, pursuant to the exercise by such tenant of any expansion right or option contained in such tenant’s lease as originally entered into, provided such additional space (i) is contiguous to, and on the same
floor as, the premises demised by such lease as originally entered into, and (ii) is no larger than 25% of the premises demised by such lease as originally entered into. 
 (ii) Landlord may, from time to time, give one or more Offer Notices. The term “Offer Notice” shall mean a notice:

  

	 	(1)	referring to this Paragraph 35(E); 

  

	 	(2)	describing the premises to which it relates (the “Offer Space”) and, if the Offer Space includes a portion less than all of the rentable area of any floor,
including a floor plan of such floor with such portion hatched; 

  

	 	(3)	setting forth the date (which shall be a single date and shall be no earlier than 30 days after and no later than (a) 547 days after the date of such Offer Notice if the Offer
Space includes 3 or fewer full floors of the Building, or (b) otherwise, 912 days after the date of such Offer Notice) on which, if Tenant exercises its right pursuant to this Paragraph 35(E) to lease such Offer Space, Landlord
reasonably believes, on the basis of written agreements then in effect, that it will be able to deliver to Tenant vacant possession thereof (the “Scheduled Offer Space Delivery Date”); 

  

	 	(4)	setting forth Landlord’s good faith opinion of the Fair Market Rental Value of the Offer Space; and 

  

	 	(5)	if no portion of such Offer Space is Senior ROFO Space and all or any portion of such Offer Space is subject to a Permitted Superior Expansion Right, so stating and identifying the
lease containing such Permitted Superior Expansion Right (which shall be either the Hyatt Lease or the Mayer Brown Lease), and setting forth (i) the portion of such Offer Space subject thereto (including, if less than all of such Offer Space on
a floor, a floor plan showing the same), and (ii) the date on which Landlord is required, if such Permitted Superior Expansion Right is exercised, to deliver such portion of such Offer Space to the holder of such Superior Expansion Right (the
“Permitted Superior Expansion Right Delivery Date”). 

 Each Offer Notice shall constitute a representation by
Landlord that all leases covering any of such Offer Space have expired or been terminated or, pursuant to the terms thereof or other written agreements then in effect, will expire or terminate with respect to such Offer Space on or prior to the
Scheduled Offer Space Delivery Date set forth in such Offer Notice. 
  

 9 

 If pursuant to the provisions of any other lease (a “Recapture Provision”) Landlord
shall become entitled to recapture any space in the Building in connection with a proposed assignment or sublease (a “Recapture Space”), Landlord shall, within five (5) Business Days of its receipt of the notice from the
other tenant entitling Landlord to recapture, give to Tenant an Offer Notice with respect to such space. Such Offer Notice (a “Recapture Offer Notice”) shall, in addition to the information required by the foregoing provisions
of this Paragraph 35(E)(ii) to be included therein, set forth (a) that it relates to space which Landlord is entitled to recapture, (b) the last day on which Landlord is permitted by the terms of the applicable lease to exercise
such recapture right (the “Landlord’s Exercise Deadline Date”), (c) a schedule of the net base rent that such other tenant is obligated to pay for such Recapture Space (the “Recapture Space Rent
Schedule”), and (d) the date on which the then-committed term of such lease shall expire with respect to the Recapture Space (the “Recapture Space Expiration Date”) and be accompanied by a copy of the provisions
of such other lease establishing the Recapture Space Rent Schedule and the Recapture Space Expiration Date. No Offer Notice shall include Recapture Space and any space which is not Recapture Space. Landlord shall not waive or amend any lease so as
to eliminate any Recapture Provision. 
 (iii) Tenant shall have the right, by notice to Landlord given within twenty
(20) Business Days of its receipt of any Offer Notice (an “Acceptance Notice”), to lease all or any portion of the Offer Space covered by such Offer Notice; provided, however, that 
  

	 	(1)	if Tenant elects to lease and include in its Acceptance Notice any of such Offer Space on any floor of the Building then Tenant shall be obligated to lease and include in such
Acceptance Notice all of such Offer Space on such floor of the Building; 

  

	 	(2)	if the Offer Space includes a block of two or more contiguous full floors (an “Offer Space Block”), then 

  

	 	(i)	the term “M” shall mean the number of contiguous full floors in the block, and the term “N” shall mean the number of contiguous full floors which
Tenant desires to lease and include in its Acceptance Notice, and 

  

	 	(ii)	if N is less than M then the term “Lower N Block” shall be the block of N contiguous full floors within such Offer Space Block containing the lowest full floor
thereof (or if N is one, just such lowest full floor) and the term “Upper N Block” shall be the block of N contiguous full floors within such Offer Space Block containing the highest full floor thereof (or if N is one, just
such highest full floor), and 

  

 10 

	 	(A)	if only one of the N Blocks is contiguous to the Premises, Tenant shall lease and include in its Acceptance Notice, such N Block, 

  

	 	(B)	if both of such N Blocks are contiguous to the Premises, Tenant shall lease and include in its Acceptance Notice, either of such N Blocks (as Tenant shall elect), and

  

	 	(C)	if neither N Block is contiguous to the Premises, Tenant shall lease and include in its Acceptance Notice either of such N Blocks (as Tenant shall elect) and Landlord shall
have the right in any case under this clause (C), by notice to Landlord given within thirty (30) days of such Acceptance Notice, to substitute the other N Block therefor, 

  

	 	(3)	in case of any Recapture Offer Notice, the Acceptance Notice (herein, a “Recapture Acceptance Notice”) 

  

	 	(a)	must be given, if at all, no later than the earlier of (i) the date provided for above in this Paragraph 35(E)(iii), or (ii) the second (2nd) Business Day prior to
Landlord’s Exercise Deadline Date set forth in such Recapture Offer Notice; and 

  

	 	(b)	must include all of such Offer Space; 

  

	 	(4)	if Tenant shall give such any Acceptance Notice later than 1095 days before the Initial Term Expiration Date and Tenant shall not have theretofore given (and waived (or been deemed
to have waived) its right to rescind) the First Renewal Notice then such Acceptance Notice shall not be valid unless accompanied or preceded by a Renewal Commitment Notice for the First Renewal Period; and 

  

	 	(5)	if Tenant shall give any such Acceptance Notice later than 1095 days before the fifth anniversary of the Initial Term Expiration Date and Tenant shall not have theretofore given
(and waived (or been deemed to have waived) its right to rescind) the Second Renewal Notice then such Acceptance Notice shall not be valid unless accompanied or preceded by a Renewal Commitment Notice for the Second Renewal Period.

 The space as to which Tenant timely gives an Acceptance Notice is herein called an “Accepted Offer Space.”
Tenant shall, in its Acceptance Notice, state whether it agrees with Landlord’s estimate of the Fair Market Rental Value set forth in Landlord’s Offer Notice and, if not, Tenant shall include in its Acceptance Notice a statement of
Tenant’s good faith opinion of the Fair Market Rental Value of the Accepted Offer Space. 
  

 11 

 (iv) If Tenant timely gives an Acceptance Notice then (i) on the Scheduled Offer
Space Delivery Date, Landlord shall deliver the Accepted Offer Space to Tenant with all Base Building Work therein complete, ordinary wear and tear excepted, and otherwise in “as-is” condition (except that in the case of a Recapture
Acceptance Notice such Accepted Offer Space shall be delivered in “as-is” condition), and (ii) the Accepted Offer Space shall be included in the Premises upon the same terms, covenants and conditions as are applicable to the Primary
Office Premises, except to the extent, if any, otherwise provided below: 
  

	 	(1)	the term of the letting of the Accepted Offer Premises shall expire on the Initial Term Expiration Date, and the Accepted Offer Premises shall be subject to Paragraphs
35(F) and (G); provided, however, that 

  

	 	(a)	if prior to the giving of such Acceptance Notice, the First Renewal Notice shall have been given then the term of the letting of such Accepted Offer Space shall expire on the First
Renewal Term Expiration Date, and the Accepted Offer Space shall be subject to Paragraph 35(G); provided, however, that if such First Renewal Notice shall have been or shall thereafter be rescinded pursuant to Paragraph 35(F)(iii) this
clause (a) shall be disregarded; 

  

	 	(b)	if prior to the giving of such Acceptance Notice, the Second Renewal Notice shall have been given then the term of the letting of such Accepted Offer Space shall expire on the
Second Renewal Term Expiration Date; provided, however, that if such Second Renewal Notice shall have been or shall thereafter be rescinded pursuant to Paragraph 35(G)(iii) this clause (b) shall be disregarded; 

  

	 	(c)	if such Accepted Offer Space or any portion thereof shall be subject to a Permitted Superior Expansion Right (and Landlord shall have so stated in its Offer Notice), then the term
of the letting with respect to such Accepted Offer Space or portion thereof shall expire on the earlier of (a) the day provided by the foregoing provisions of this Paragraph 35(E)(iv)(1), and (b) the day preceding the Landlord
Permitted Superior Expansion Right Delivery Date; 

  

 12 

	 	(d)	if such Accepted Offer Space or any portion thereof shall be located on the floor(s) on which the Second Expansion Premises are located and, at the time of Tenant’s giving
of the Acceptance Notice with respect thereto, the Second Expansion Option shall not have lapsed without exercise, then the term of the letting with respect to such Accepted Offer Space or portion thereof shall expire on the earlier of (a) the
date provided by the foregoing provisions of this Paragraph 35(E)(iv)(1), and (b) the day preceding the Second Expansion Option Scheduled Delivery Date; and 

  

	 	(e)	if Landlord shall have given a Recapture Offer Notice setting forth a Recapture Space Expiration Date that is later than the date on which (in the absence of this clause
(e)) the term of the letting of such Accepted Offer Premises would expire pursuant to the foregoing provisions of this Section 35(E)(iv)(1) (any such Accepted Offer Premises being herein referred to as “Long Term Recapture
Space”), the term of the letting of the Accepted Offer Space shall expire on such Recapture Space Expiration Date so set forth (the date of such expiration being herein referred to as the “Long Term Recapture Space Expiration
Date”). 

  

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses with respect to such Accepted Offer Space shall commence to be payable on the earlier of (such earlier date
being herein called the “Offer Space Rent Commencement Date”): 

  

	 	(a)	the date which is one hundred twenty (120) days after the later of (i) the date on which Landlord actually tenders possession of the Accepted Offer Space to Tenant in the
condition required by this Paragraph 35(E)(iv)), and (ii) the Scheduled Offer Space Delivery Date; or 

  

	 	(b)	the date Tenant commences to conduct ordinary business in the Offer Space; 

  

	 	(3)	The amount of Net Rent with respect to the Offer Space shall be equal to: 

  

	 	(a)	except in the case of a Recapture Acceptance Notice, (x) if Tenant in its Acceptance Notice shall have agreed with Landlord’s estimate of the Fair Market Rental Value set
forth in the Offer Notice, such Fair Market Rental Value so set forth, (y) otherwise, the Fair Market Rental Value of the Accepted Offer Space as determined pursuant to Paragraph 35(E)(viii); and 

  

 13 

	 	(b)	in the case of a Recapture Acceptance Notice, the greater of (x) the Fair Market Rental Value of the Accepted Offer Space, determined either by Tenant having agreed in its
Recapture Acceptance Notice with Landlord’s estimate of the Fair Market Rental Value set forth in the Offer Notice or determined pursuant to Paragraph 35(E)(viii), and (y) that provided by the Recapture Space Rent Schedule.

  

	 	(4)	The Rentable Area of the Premises shall be increased by the Rentable Area of the Offer Space; and 

  

	 	(5)	Tenant’s Pro Rata Share shall be increased to reflect the Rentable Area of the Accepted Offer Space, effective as of the Accepted Offer Space Rent Commencement Date.

 Following the giving by Tenant of an Acceptance Notice and the determination of the Net Rent with respect to the Accepted
Offer Space covered thereby, and within thirty (30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the Accepted Offer
Space pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or refusal of either party to do so, however, shall not affect the validity of the leasing of the Accepted Offer Space. 
 (v) So long as, when Tenant gives an Offer Notice, it is entitled, on the basis of written agreements then in effect, to possession of the
Offer Space no later than the Scheduled Offer Space Delivery Date set forth therein, Landlord shall not be deemed to be in default under this Lease if it is unable to deliver any Accepted Offer Space on such Scheduled Offer Space Delivery Date due
solely to the failure of such tenant or any of its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver possession of any Accepted Offer Space in the condition required by Paragraph 35(E)(iv) by the
90th day after the Scheduled Offer Space Delivery Date, Tenant shall have the option, by written notice to Landlord given at any time prior to the delivery to Tenant of the Accepted Offer Space in the condition required by Paragraph 35(E)(iv),
to rescind its Acceptance Notice, in which event Landlord shall have no liability to Tenant on account of such failure timely to deliver (except that Landlord shall not be released from such liability if the representation set forth in the
penultimate paragraph of Paragraph 35(E)(ii) shall have been breached). Landlord will use commercially reasonable efforts to regain possession of such Accepted Offer Space as promptly as reasonably possible, including the prosecution
of litigation against any occupant of such space. 
  

	 	(vi) (1)	 If in response to any Offer Notice Tenant shall fail timely to deliver an Acceptance Notice (or the same shall be rescinded pursuant to
Paragraph 35(E)(v)) then Landlord shall be permitted to lease all or any portion of the Offer Space covered by such Offer Notice to any person or persons for delivery no earlier than the Scheduled Offer Space Delivery Date set forth in
such Offer Notice (and otherwise on such terms as Landlord shall determine in its discretion (subject to Tenant’s rights under this Paragraph 35(E) with respect to renewals, 

  

 14 

	 	 
extensions and expansions and Tenant’s rights under Paragraph 35(D) if applicable)); provided, however, that immediately subsequent to the
original entering into of any such lease the space covered thereby shall again become subject to this Article such that Landlord shall not (except as permitted by the other provisions of Paragraph 35(E)(i), if and to the extent
applicable) subsequently lease such space except pursuant to this Paragraph 35(E)(vi) based upon a subsequent Offer Notice given to Tenant with respect thereto. 

  

	 	(2)	If in response to any Offer Notice Tenant shall timely deliver an Acceptance Notice with respect to less than all of the Offer Space covered by such Offer Notice then Landlord shall
be permitted to lease all or any portion of the balance of such Offer Space covered by such Offer Notice to any person or persons for delivery no earlier than the Scheduled Offer Space Delivery Date set forth in such Offer Notice (and otherwise on
such terms as Landlord shall determine in its discretion (subject to Tenant’s rights under this Paragraph 35(E) with respect to renewals, extensions and expansions and Tenant’s rights under Paragraph 35(D) if
applicable)); provided, however, that immediately subsequent to the original entering into of any such lease the space covered thereby shall again become subject to this Article such that Landlord shall not (except as permitted by the other
provisions of Paragraph 35(E)(i), if and to the extent applicable) subsequently lease such space except pursuant to this Paragraph 35(E)(vi) based upon a subsequent Offer Notice given to Tenant with respect thereto.

 (vii) The term “Fair Market Rental Value” of any Accepted Offer Space shall mean the fair
market amount of net base rent, expressed in dollars and cents per square foot of Rentable Area of the Accepted Offer Space (i.e. exclusive of Taxes, Net Shared Facilities Costs and Operating Expenses) (fixed or with specified percentage
increases at specified intervals), under a lease for a term commencing on the applicable Scheduled Offer Space Delivery Date and ending on a date which is the later to occur of (a) the tenth (10) anniversary of the Scheduled Offer Space
Delivery Date, and (b) the date provided for in Paragraph 35(E)(iv) for the expiration of the term of the letting of such Accepted Offer Space, and otherwise on the terms and conditions of this Lease to be applicable to such Accepted
Offer Space, determined as if the Accepted Offer Space were then available in the then rental market and assuming 
  

	 	(1)	that Landlord has a reasonable time to locate a tenant; and 

  

	 	(2)	that neither Landlord not such tenant is under any compulsion to rent. 

  

 15 

 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers
to or considers any transaction in which the landlord provided free rent or a tenant improvement allowance or any work to prepare the premises for the tenant’s occupancy, or any lease takeover or any other concession (all of the foregoing being
herein called a “Leasing Concession”), then in so referring to or considering such transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction shall be adjusted downward by
subtracting the product of 12 multiplied by the amount which, if taken monthly over the term of such transaction, would have a net present value (using such interest rate as the arbitrator or other person applying this paragraph believes to be
appropriate considering market practices) as of the commencement of such transaction equal to the amount of such Leasing Concession. 
 (viii) If (a) in Tenant’s Acceptance Notice Tenant shall have stated that it does not agree with Landlord’s estimate of the Fair Market Rental Value set forth in Landlord’s Offer Notice and shall
have included therein a statement of Tenant’s good faith opinion of the Fair Market Rental Value of the Accepted Offer Space, and (b) the parties are unable to agree on the Fair Market Rental Value within thirty (30) days after the
giving of Tenant’s Acceptance Notice (the “Accepted Offer Space Negotiation Period”), then (x) Landlord and Tenant nonetheless shall be bound to the leasing of the Accepted Offer Space pursuant to this
Paragraph 35(E), and (y) the Fair Market Rental Value shall be determined by arbitration pursuant to Article 36 (and Landlord and Tenant shall be bound to the Fair Market Rental Value as so determined). 
 (F) First Renewal Option. Tenant shall have the option to extend the Term of this Lease as to the First Renewal Premises for five (5) years
commencing upon the expiration of the initial term (the “First Renewal Term”). 
 (i) The term “First
Possible Renewal Premises” shall mean all of the Premises subject to this Lease at the time of the giving of the First Renewal Notice, including any Premises as to which an Acceptance Notice shall have been given pursuant to
Paragraph 35(E) even if the same shall not yet have been delivered to Tenant. The term “First Renewal Premises” shall mean all or such portions of the First Possible Renewal Premises as shall be specified in the First
Renewal Notice, subject to the following: 
  

	 	(1)	the First Renewal Premises shall include the Original Premises, and 

  

	 	(2)	if any portion of First Possible Renewal Premises located on any floor are included in the First Renewal Premises all portions of the First Possible Renewal Premises located on such
floor shall be included. 

 (ii) The First Renewal Term shall be upon the terms and conditions contained herein,
including without limitation the payment of Tenant’s Pro Rata Share of Taxes and Operating Expenses, determined on the same basis as set forth in Article 3 of this Lease, except that (a) the Net Rent for the First Renewal Term shall
be the Fair Market Rental Value of the First Renewal Premises for the First Renewal Term and (b) if the First Renewal Premises shall be less than the entire First Possible Renewal Premises, Tenant’s Pro Rata Share shall be recalculated on
the basis of the First Renewal Premises. 
  

 16 

 (iii) Tenant shall provide notice to Landlord (“First Renewal
Notice”) of Tenant’s exercise of the First Renewal Options no later than the day 612 days prior to the Initial Term Expiration Date. On the day 567 days prior to the Initial Term Expiration Date (or, if such day is not a Business
Day, on the next Business Day), Landlord and Tenant shall, at the Building’s management office, each simultaneously submit to the other, in a sealed envelope, its signed written good faith estimate of the Fair Market Rental Value (the
“Preliminary Estimates”). Each Preliminary Estimate shall consist of only a single fixed dollar amount per square foot of Rentable Area. Tenant shall have the right, by notice to Landlord given within 20 days of the exchange of
Preliminary Estimates, to rescind the First Renewal Notice, whereupon, if exercised, Tenant shall have no further rights to extend the Term pursuant to this Paragraph 35(F). If Tenant does not timely rescind the First Renewal Notice, Landlord and
Tenant hereby agree to be conclusively bound to the renewal of this Lease for the First Renewal Premises for the First Renewal Term at the Fair Market Rental Value determined by arbitration pursuant to Article 36. 
 (iv) If the Premises includes any Long Term Recapture Space with a Long Term Recapture Space Expiration Date during or after the Second
Renewal Term then such Long Term Recapture Space shall be excluded from the First Possible Renewal Premises. If the Premises include any Long Term Recapture Space with a Long Term Recapture Space Expiration Date during the First Renewal Term then
(i) such Long Term Recapture Space shall be included in the First Possible Renewal Premises and (ii) if included by Tenant in the First Renewal Premises, the renewal thus effected with respect thereto shall be only for (and the Fair Market
Rental Value provided for in this Article 35(F) shall be payable only for) the period commencing immediately after the Long Term Recapture Space Expiration Date with respect thereto and ending at the end of the First Renewal Term. This
Paragraph 35(F)(iv) shall not be construed to result in the expiration of the letting of any Long Term Recapture Space prior to the Long Term Recapture Space Expiration Date with respect thereto. 
 (v) The term “Fair Market Rental Value” of the First Renewal Premises shall mean the fair market amount of net fixed base
rent per square foot of Rentable Area of the First Renewal Premises (i.e. exclusive of Taxes and Operating Expenses) under a lease for a term equal to the First Renewal Term and otherwise on all of the terms and conditions of this Lease to be
applicable to the First Renewal Premises for the First Renewal Term, determined as if the First Renewal Premises were then available in the then rental market, and assuming 
  

	 	(1)	that Landlord has a reasonable time to locate a tenant, 

  

	 	(2)	that neither Landlord nor such tenant is under any compulsion to rent. 

  

 17 

 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers
to or considers any transaction in which the landlord provided free rent or a tenant improvement allowance or any work to prepare the premises for the tenant’s occupancy, or any lease takeover or any other concession (all of the foregoing being
herein called a “Leasing Concession”), then in so referring to or considering such transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction shall be adjusted downward by
subtracting the product of 12 multiplied by the amount which, if taken monthly over the term of such transaction, would have a net present value (using such interest rate as the arbitrator or other person applying this paragraph believes to be
appropriate considering market practices) as of the commencement of such transaction equal to the amount of such Leasing Concession. 
 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers to or considers any transaction in which a method different from the Measurement Method was used in determining rentable and usable
areas, then in so referring to or considering such transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction shall be adjusted accordingly. 
 (G) Second Renewal Option. Tenant shall have the option to extend the Term of this Lease as to the Second Renewal Premises for five (5) years
commencing upon the expiration of the First Renewal Term (the “Second Renewal Term”). 
 (i) The term
“Second Possible Renewal Premises” shall mean all of the Premises subject to this Lease at the time of the giving of the Second Renewal Notice, including any Premises as to which an Acceptance Notice shall have been given pursuant
to Paragraph 35(E) even if the same shall not yet have been delivered to Tenant. The term “Second Renewal Premises” shall mean all or such portions of the Second Possible Renewal Premises as shall be specified in the
Second Renewal Notice, subject to the following: 
  

	 	(1)	the Second Renewal Premises shall include the Original Premises, and 

  

	 	(2)	if any portion of Second Possible Renewal Premises located on any floor are included in the Second Renewal Premises all portions of the Second Possible Renewal Premises located on
such floor shall be included; and 

 (ii) The Second Renewal Term shall be upon the terms and conditions
contained herein, including without limitation the payment of Tenant’s Pro Rata Share of Taxes and Operating Expenses, determined on the same basis as set forth in Paragraph 3(C) of this Lease, except that (a) the Net Rent for
the Second Renewal Term shall be the Fair Market Rental Value of the Second Renewal Premises for the Second Renewal Term and (b) if the Second Renewal Premises shall be less than the entire Second Possible Renewal Premises, Tenant’s Pro
Rata Share shall be recalculated on the basis of the Second Renewal Premises. 
  

 18 

 (iii) Tenant shall provide notice to Landlord (“Second Renewal
Notice”) of Tenant’s exercise of the Second Renewal Options no later than the day 612 days prior to the First Renewal Term Expiration Date. On the day 567 days prior to the First Renewal Term Expiration Date (or, if such day is
not a Business Day, on the next Business Day), Landlord and Tenant shall, at the Building’s management office, each simultaneously submit to the other, in a sealed envelope, its signed written good faith estimate of the Fair Market Rental Value
(the “Preliminary Estimates”). Each Preliminary Estimate shall consist of only a single fixed dollar amount per square foot of Rentable Area. Tenant shall have the right, by notice to Landlord given within 20 days of the exchange of
Preliminary Estimates, to rescind the Second Renewal Notice, whereupon, if exercised, Tenant shall have no further rights to extend the Term under this Paragraph 35(G). If Tenant does not timely rescind the Second Renewal Notice, Landlord and Tenant
hereby agree to be conclusively bound to the renewal of this Lease for the Second Renewal Premises for the Second Renewal Term at the Fair Market Rental Value determined by arbitration pursuant to Article 36. 
 (iv) If the Premises includes any Long Term Recapture Space with a Long Term Recapture Space Expiration Date after the Second Renewal Term
then such Long Term Recapture Space shall be excluded from the Second Possible Renewal Premises. If the Premises include any Long Term Recapture Space with a Long Term Recapture Space Expiration Date during the Second Renewal Term then (i) such
Long Term Recapture Space shall be included in the Second Possible Renewal Premises and (ii) if included by Tenant in the Second Renewal Premises, the renewal thus effected with respect thereto shall be only for (and the Fair Market Rental
Value provided for in this Article 35(G) shall be payable only for) the period commencing immediately after the Long Term Recapture Space Expiration Date with respect thereto and ending at the end of the Second Renewal Term. This Paragraph
35(G)(iv) shall not be construed to result in the expiration of the letting of any Long Term Recapture Space prior to the Long Term Recapture Space Expiration Date with respect thereto. 
 (v) The term “Fair Market Rental Value” of the Second Renewal Premises shall mean the fair market amount of net fixed
base rent per square foot of Rentable Area of the Second Renewal Premises (i.e. exclusive of Taxes and Operating Expenses) under a lease for a term equal to the Second Renewal Term and otherwise on all of the terms and conditions of this Lease
to be applicable to the Second Renewal Premises for the Second Renewal Term, determined as if the Second Renewal Premises were then available in the then rental market, and assuming 
  

	 	(1)	that Landlord has a reasonable time to locate a tenant, 

  

	 	(2)	that neither Landlord nor such tenant is under any compulsion to rent. 

 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers to or considers any transaction in which the landlord provided free rent or a tenant improvement allowance or
any work to prepare the premises for the tenant’s occupancy, or any lease takeover or any other concession (all of the foregoing being herein called a “Leasing 

  

 19 

 
Concession”), then in so referring to or considering such transaction for purposes of determining Fair Market Rental Value the net base rent
provided for in such transaction shall be adjusted downward by subtracting the product of 12 multiplied by the amount which, if taken monthly over the term of such transaction, would have a net present value (using such interest rate as the
arbitrator or other person applying this paragraph believes to be appropriate considering market practices) as of the commencement of such transaction equal to the amount of such Leasing Concession. 
 If and to the extent that any arbitrator or other person determining the Fair Market Rental Value refers to or considers any transaction in which a method
different from the Measurement Method was used in determining rentable and usable areas, then in so referring to or considering such transaction for purposes of determining Fair Market Rental Value the net base rent provided for in such transaction
shall be adjusted accordingly.

 (i) Tenant shall not be entitled to exercise a Renewal Option if on the date Tenant exercises such Renewal Option, (a) a monetary or
material non-monetary Default has occurred and is continuing, or (b) this Lease or Tenant’s right of possession has been terminated, or (c) this Lease is not in full force and effect. Tenant shall not be entitled to the Second Renewal
Option unless Tenant shall have exercised the First Renewal Option. 
 (ii) Following exercise by Tenant of a Renewal Option
and determination of the Net Rent for the respective Renewal Term, at the request of either party hereto and within thirty (30) days after such request, Landlord and Tenant shall enter into a supplement to this Lease confirming the renewal of
this Lease for such Renewal Term, the Renewal Premises, and the term of such renewal. The failure or refusal of either party to do so, however, shall not affect the validity of the exercise of the Renewal Option.

giving a First Renewal Notice, but shall fail timely to give a Renewal Notice conforming to the requirement of this Paragraph 35(H)(iv), then Tenant shall be deemed timely to have given a First Renewal Notice setting forth as the First Renewal
Premises all of the First Possible Renewal Premises. If Tenant gives a First Renewal Commitment Notice, Tenant shall no 

  

 20 

 
longer have the right to rescind the First Renewal Notice and, if Tenant shall have theretofore given the First Renewal Notice, the same shall be deemed
amended to include in the First Renewal Premises (in addition to any other premises required to be included) all Accepted Offer Space as to which Tenant gives an Acceptance Notice together with or after the date of such First Renewal Commitment
Notice. 
 (v) The term “Second Renewal Commitment Notice” shall mean a notice referring to this Paragraph
35(H)(v), in which Tenant irrevocably agrees to give (and not to rescind) the Second Renewal Notice and to include in the Second Renewal Premises (in addition to any other premises required to be included) all Accepted Offer Space as to
which Tenant gives an Acceptance Notice together with or after the date of such Second Renewal Commitment Notice. If Tenant gives a Second Renewal Commitment Notice prior to its giving a Second Renewal Notice, but shall fail timely to give a Renewal
Notice conforming to the requirement of this Paragraph 35(H)(v), then Tenant shall be deemed timely to have given a Second Renewal Notice setting forth as the Second Renewal Premises all of the Second Possible Renewal Premises. If Tenant gives a
Second Renewal Commitment Notice, Tenant shall no longer have the right to rescind the Second Renewal Notice and, if Tenant shall have theretofore given the Second Renewal Notice, the same shall be deemed amended to include in the Second Renewal
Premises (in addition to any other premises required to be included) all Accepted Offer Space as to which Tenant gives an Acceptance Notice together with or after the date of such Second Renewal Commitment Notice. 
 (I) Contraction Option. 
 (i) Tenant, by delivering notice to Landlord on or prior to the 180th day after the date of this Lease, shall have the one time option (the “South Contraction Option”) to eliminate the South Eighth Floor Premises from the Original Premises. 
  

	 	(1)	If Tenant fails to timely deliver such written notice to Landlord, Tenant shall be deemed to have elected not to exercise the South Contraction Option and shall forfeit all rights
pursuant to this Paragraph 35(I)(i). 

  

	 	(2)	If Tenant properly exercises the South Contraction Option, then, from and after the date of such exercise, the South Eighth Floor Premises shall no longer be deemed a part of the
Original Premises. 

 (ii) Tenant, by delivering notice to Landlord on or prior to the 180
th day after the date of this Lease, shall have the one time option (the
“Full Contraction Option”) to eliminate the Eighth Floor Premises from the Original Premises. 
  

	 	(1)	If Tenant fails to timely deliver such written notice to Landlord, Tenant shall be deemed to have elected not to exercise the Full Contraction Option and shall forfeit all rights

Premises. 

 (iii) In no event shall Tenant be permitted to exercise both the South Contraction Option and the
Full Contraction Option. 
 (iv) Following exercise by Tenant of the South Contraction Option or the Full Contraction Option,
and within thirty days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually acceptable supplement to this Lease confirming the elimination of the South Eighth Floor Premises or the Eighth Floor
Premises from the Original Premises pursuant hereto. The failure or refusal by either party to do so, however, shall not affect the validity of the elimination of the South Eighth Floor Premises or the Eighth Floor Premises from the Original
Premises. 
 (v) If Tenant shall (A) exercise the South Contraction Option and not exercise the South
Contraction Rescission Option, or (B) exercise the Full Contraction Option and exercise the First Expansion Option with respect to the North Eighth Floor Premises only then, on or before the Substantial Completion Date, Landlord shall construct
and finish in accordance with Building standards all corridors, elevator lobbies and other common areas on the 8th floor required for the same to be occupied as a multi-tenant floor (the “8th Floor Division Work”). 
 (J) Divided
Floors. 
 (i) If the Premises shall include some but not all of the office areas on a floor and thereafter shall come to
include all of the office areas on any floor, then (a) the Premises shall be deemed also to include the elevator lobby, common corridor and other areas which, on a divided floor, would constitute Common Area, and (b) the Rentable Area of
the Premises on such floor shall be calculated as if Tenant had leased all of such floor concurrently as a single floor. 
 (ii) No provision of this Article 35 which authorizes Landlord to lease any portion of the Building to any third party shall include, on any divided floor, the portion thereof required for Common Areas. 
 (K) Tenant’s Right to Lease from Building Tenants. Notwithstanding any provision of any lease or other agreement which may give Landlord the
right to withhold consent to any sublease to Tenant, or any assignment of any lease to Tenant, or any right to recapture (by any means) the premises proposed to be subleased to Tenant or the premises covered by any lease proposed to be assigned
to Tenant, Landlord agrees that (i) it shall consent to any such sublease or assignment and shall not exercise any such recapture right unless required to do so under any Permitted Superior Expansion Right, and (ii) that Tenant may furnish
a copy of this Paragraph 35(K) to any Building tenant, and any such Building tenant may rely thereon.

 (ii) Tenant shall not be entitled to exercise the First Hold Expansion Option, if,
(x) on or before Tenant’s exercise thereof, this Lease or Tenant’s right of possession shall have been terminated and this Lease shall not then be in full force and effect, or (y) Tenant shall have previously exercised any

	 	(3)	The First Hold Expansion Space shall become part of the First Segment and shall be delivered by Landlord to Tenant on the First Segment Delivery Date. 

 Following Tenant’s exercise of the First Hold Expansion Option, and within thirty (30) days following written request by either Landlord or
Tenant, Landlord and Tenant shall enter into a mutually acceptable supplement to this Lease confirming the terms, conditions and provisions applicable to the related First Hold Expansion Space as determined in accordance herewith. Failure or refusal

(1/2) floor of space remaining on the thirty-fourth (34th) floor if Tenant has not exercised the first Pre-Occupancy Contraction Option, but has previously exercised the second Pre-Occupancy Contraction Option with respect to the other
one-half (1/2) floor of space on the thirty-fourth (34th) floor of the Building, and (d) the entire forty-sixth (46th) floor of the Building if Tenant has exercised either the First Hold Expansion Option, the first Pre-Occupancy

Expansion Space Rent Commencement Date, and (II) with respect to the First Expansion Space not located on the 46th floor, if any of the First Expansion space includes one-half (1/2) floor space in the Building other than the forty-sixth
(46th) floor, then the Net Rent for such one-half (1/2) floor shall be the Rentable Area thereof multiplied by the then Net Rent per square foot of Rentable Area payable by Tenant with respect to the Premises immediately prior to the
applicable Expansion Space Rent Commencement Date, subject in each case to further escalation as provided in Exhibit B attached hereto for the balance of the Term, and payable thereafter, from time to time, in the amounts set forth in

the Commencement Date. Tenant shall no later than the first day of the sixty-seventh (67th) full calendar month following the Commencement Date deliver to Landlord a notice (the “Tenant’s Second Expansion Notice”) exercising the Second Expansion Option. If Tenant fails to timely deliver the Second
Expansion Notice, then Tenant shall be deemed to have waived the Second Expansion Option; except, that if on the last day of the sixty-sixth (66th) full calendar month following the Commencement Date, Tenant is then leasing all of the Second
Expansion Space as Encumbered Accepted Offer Space, then Tenant shall be deemed to have delivered the Second Expansion Notice with respect to such Encumbered Accepted Offer Space, unless on or before such last day Tenant delivers a notice to
Landlord expressly electing not to exercise the Second Expansion Option with respect to such Encumbered Accepted Offer Space. Net Rent for the Second Expansion Space shall be the Rentable Area thereof multiplied by the then Net Rent per rentable

  

 3 

 
square foot payable by Tenant with respect to initial Premises (excluding the 46th floor) immediately prior to the applicable Expansion Space Rent
Commencement Date, subject to escalation as provided in Exhibit B attached hereto for the balance of the Term, and payable thereafter, from time to time, in the amounts set forth in Exhibit B attached hereto. 
 (iii) Third Expansion. Subject to the terms and conditions contained herein, and regardless of whether
Tenant has exercised the First Expansion Option or the Second Expansion Option, Tenant shall have the right to elect to expand the Premises (the “Third Expansion Option”) as of the Third Expansion Effective Date to include one full
floor of space (the “Third Expansion Space”) that is either (a) the thirtieth (30th) floor of the Building if Tenant has exercised neither the First Hold Expansion Option nor any Pre-Occupancy Contraction Option, (b) the thirty-first (31st) floor of the Building if Tenant previously

last day of the ninetieth (90th) full calendar month following the Commencement Date, Tenant is then leasing all of the Third Expansion Space as Encumbered Accepted Offer Space, then Tenant shall be deemed to have delivered the Third Expansion
Notice with respect to such Encumbered Accepted Offer Space, unless on or before such last date Tenant delivers a notice to Landlord expressly electing not to exercise the Third Expansion Option with respect to such Encumbered Accepted Offer Space.
Net Rent for the Third Expansion Space shall be the Rentable Area thereof multiplied by the then Net Rent per rentable square foot payable by Tenant with respect to the initial Premises (excluding the 46th floor) immediately prior to the applicable Expansion Space Rent Commencement Date, subject to escalation as provided
in Exhibit B attached hereto for the balance of the Term, and payable thereafter, from time to time, in the amounts set forth in Exhibit B attached hereto.

respect to such Encumbered Accepted Offer Space, unless on or before such last day Tenant delivers a notice to Landlord expressly electing not to exercise the Fourth Expansion Option with respect to such Encumbered Accepted Offer Space. Net Rent for
the Fourth Expansion Space shall be the Rentable Area thereof multiplied by the then Net Rent per rentable square foot payable by Tenant with respect to the initial Premises (excluding the 46th floor) immediately prior to the applicable Expansion Space Rent Commencement Date, subject to escalation as provided in
Exhibit B attached hereto for the balance of the Term, and payable thereafter, from time to time, in the amounts set forth in Exhibit B attached hereto.

included in the Premises effective as of the applicable Expansion Effective Date on the same terms, covenants and conditions as are contained in this Lease (including the provisions of the Workletter), with the following exceptions and
modifications: 
  

	 	(1)	The Rent for such Expansion Space, at the rates provided above, shall commence upon the date (an “Expansion Space Rent Commencement Date”) that is either
(a) the date of the expiration of the Encumbered Offer Term, if any of such Expansion Space is Encumbered Accepted Offer Space, or (b) if any such Expansion Space is not Encumbered Accepted Offer Space, then the date that is the earlier of
(I) one hundred twenty (120) days following the date (the “Expansion Effective Date”) that is the later of, (x) the Expansion Target Date (or Extended Effective Date, if applicable) applicable to the Expansion Space
specified above and (y) the date Landlord tenders possession of such Expansion Space to Tenant in the condition required by Paragraph 35(B)(vii) (4) and (5) (including installation by Landlord of Required Landlord Work described
in Subparagraph (4) below), and (II) the date that Tenant occupies such space for the normal conduct of Tenant’s business therein. Landlord agrees that if any Expansion Space becomes vacant, Tenant has previously exercised the applicable
Expansion Option, and Landlord shall have completed the Required Landlord Work, Tenant shall have the right to occupy such space prior to the applicable Expansion Target Date (or Extended Effective Date, if applicable) for the purpose of preparing
such Expansion Space for Tenant’s occupancy; 

  

	 	(2)	The Rentable Area of the Premises shall be increased by the Rentable Area of such Expansion Space; 

  

	 	(3)	Tenant’s Pro Rata Share shall be increased to reflect the Rentable Area of such Expansion Space effective as of the applicable Expansion Space Rent Commencement Date;

  

	 	(4)	 Landlord shall pay to Tenant the Expansion Allowance. Any such Expansion Allowance shall be used and disbursed in accordance with the provisions and procedures set
forth in Section 16 of the Workletter relating to the Premises leased to Tenant pursuant to Article 1 above. In addition to the foregoing Expansion Allowance, if any Expansion Space has not theretofore been improved for the occupancy of an
office tenant, Landlord shall further provide in such space (i) all of the Landlord’s Work, and (ii) a raised floor, ceiling, lighting and HVAC ducting system comparable or superior in quality to those constructed in the space demised
to Hyatt (other than the 46th and 47th floors) ((i) and (ii) collectively referred to as, the “Required Landlord Work”). As used herein, the term “Expansion Allowance” means the amount equal to the product
of (i) fifty dollars ($50.00) per square foot of 

  

 7 

	 	 
Rentable Area in the applicable Expansion Space, and (ii) a fraction, the numerator of which is the number of full calendar months remaining in the
initial Term hereof (without regard to any extension or renewal thereof) following the applicable Expansion Space Rent Commencement Date and the denominator of which is one hundred eighty (180). 

  

	 	(5)	Landlord shall deliver and Tenant shall accept possession from Landlord of (a) each Expansion Space (that has not been previously improved for the occupancy of an office
tenant) with all Required Landlord Work therein completed and in broom clean “as is” condition and (b) each Expansion Space that has been previously improved for the occupancy of an office tenant with all of Required Landlord
Work therein completed, ordinary wear and tear excepted, and in all other respects in the physical condition required by the prior tenant’s lease for surrender of such space, except that, the Building core shall be in substantially the same
configuration and condition required by the Construction Documents, reasonable wear and tear excepted. 

 Following exercise by
Tenant of an Expansion Option, and within thirty (30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually acceptable supplement to this Lease confirming the terms, conditions and
provisions applicable to the related Expansion Space as determined in accordance herewith. Failure or refusal of either party to execute such a supplement shall not affect the validity of the leasing of the Expansion Space in accordance with the
terms of the applicable Expansion Option. 
 (viii) Expansion Window. To permit Landlord flexibility in leasing
the Expansion Spaces prior to Tenant’s rights to expand into such space, Landlord may deliver any Expansion Space that is then occupied by another tenant to Tenant at any time within twelve (12) months following the applicable Expansion
Target Date applicable to said Expansion Space as specified above (each, an “Extended Effective Date”). Landlord will specify the precise date of Extended Effective Date by written notice to Tenant delivered not more than one
(1) month following Landlord’s receipt of the Tenant’s First Expansion Notice, Tenant’s Second Expansion Notice, Tenant’s Third Expansion Notice, Tenant’s Fourth Expansion Notice or Tenant’s Fifth Expansion Notice,
as the case may be (each, an “Expansion Extension Date Notice”). Landlord shall use reasonable efforts to endeavor, from time to time, to keep Tenant apprised of the availability of each Expansion Space on its applicable Expansion
Target Date (or, the estimated date of the Extended Effective Date). If Landlord fails to timely deliver the Expansion Extension Date Notice, then Landlord shall waive its right to extend the date of the Expansion Target Date. 
  

 8 

 (ix) Delayed Delivery. Landlord may lease the First
Expansion Space, the Second Expansion Space, the Third Expansion Space, the Fourth Expansion Space and the Fifth Expansion Space, or portions thereof, from time to time, to third parties so long as such space is scheduled to be available to be
leased to Tenant by the relevant Expansion Target Date, or, if timely exercised, the relevant Extended Effective Date. If Landlord is entitled, on the basis of written agreements then in effect, to possession of the Expansion Space on the relevant
Expansion Target Date or, if timely exercise, the relevant Extended Effective Date, as applicable, then Landlord shall not be deemed to be in default under this Lease if it is unable to deliver the First Expansion Space, the Second Expansion Space,
the Third Expansion Space, the Fourth Expansion Space or the Fifth Expansion Space, to Tenant on the relevant Expansion Target Date, or, if timely exercised, the relevant Extended Effective Date due solely to the failure of such tenant or any of its
subtenants to have vacated it by relevant Expansion Target Date or, if timely exercised, the relevant Extended Effective Date, as the case may be. Landlord agrees that for each day after the sixtieth (60th) day following the relevant Expansion Target Date (or if timely exercised, the relevant Extended Effective Date)
that Landlord fails to deliver to Tenant the relevant Expansion Space, Tenant shall be entitled to an abatement of Rent commencing upon the relevant Expansion Space Rent Commencement Date therefore equal to one (1) day’s Rent otherwise
payable with respect such Expansion Space. In addition, if Landlord fails to deliver possession of any Expansion Space in the condition required by Paragraphs 35(B)(vii)(4) and (5) by the ninetieth (90th) day after the relevant Expansion Target Date (or if timely exercised, relevant Extended Effective Date), Tenant
shall have the option by written notice to Landlord given at any time prior to the delivery to Tenant of the Expansion Space in the condition required by Paragraph 35(B)(vii) (4) and (5), to lease other space in the Building (to the extent
and if available) on a temporary basis or for the balance of the Term, as Tenant elects in its notice, and at the lesser of the Current Market Rate and the same rental rate as would have been applicable to the Expansion Space or to rescind its
relevant Expansion Notice, in either such event, Landlord shall have no liability to Tenant on account of such failure to timely deliver the Expansion Space (except that Landlord shall not be released from such liability if Landlord breached its
covenant not to lease Expansion Space for a term expiring beyond the relevant Expansion Target Date or Extended Effective Date as applicable). Landlord will in all cases use commercially reasonable efforts to regain possession of such space as
promptly as reasonably possible, including the prosecution of litigation against any occupant of such space. In addition, Landlord agrees not to grant any right to such occupant to holdover in such space. 
 (x) Substitution of Floors. If Tenant fails to exercise any Expansion Option other than the First Hold Expansion Option, or
if Tenant exercises a Five-Year Contraction Option with respect to a full floor (or more), then Landlord shall have the right to substitute the full floor of the Expansion Space to which such unexercised and expired Expansion Option relates or the
full floor of the Five Year Contraction Space for the floor originally established for any Expansion Space of any succeeding, unexercised Expansion Option. As a condition to making any such substitution, Landlord shall deliver to Tenant written
notice of any such substitution on or before the date which is sixty (60) days prior to the Expansion Effective Date for such Expansion Space. 
  

 9 

 (C) Tenant’s Right of First Offer. 
 (i) Landlord shall not lease any office space in (a) any of the 47th or 46th floors of the Building (the
“Highest ROFO Space”) other than to Hyatt pursuant to the Hyatt Lease, (b) the 23rd floor of the Building up to and including the 31st floor of the Building and the 34th or 35th floors of Building, if Tenant exercises a
Pre-Occupancy Contraction Option with respect to either or both of such floors (the “Initial ROFO Space”), and (c) the 11th floor through and including the 22nd floor of the Building (the “Contingent ROFO
Space”) other than to Hyatt pursuant to the Hyatt Lease, subject in all respects to the terms hereof (specifically excluding from the terms and operation of this Paragraph 35(C) (i) any retail space in the ground floor of the
Building, (ii) the 4th floor through and including the 10th floor of the Building, (iii) the Shared Facilities, (iv) any area in the Building to the extent affected by the terms of the last sentence of Paragraph 35(F)(ii),
(v) the 34th floor of the Building, if Tenant has exercised its Pre-Occupancy
Contraction Space Option with respect to one-half ( 1/2) floor,
and, (vi) subject to the terms of Paragraph 6(O) hereof, any storage space in the Building), including, in the case of subclauses (a),(b) and (c) above, by way of renewal, extension, expansion or right or option therefor to any
person other than pursuant to: 
  

	 	(1)	 (a) any lease of the Initial ROFO Space effected pursuant to Paragraph 35(C)(vii); and (b) any Permitted Renewal or Permitted Expansion of such lease
of Initial ROFO Space, subject, in each case, to Tenant’s Expansion Options set forth in Paragraph 35(B); and (c) if Tenant has declined to exercise its rights of first offer under this Paragraph 35(C), the exercise by (and
demise to) the tenant under the Hyatt Lease of its rights of first offer thereunder with respect to the 23rd through 27th floors of Initial ROFO Space, which is
not Encumbered Accepted Offer Space and that is leased for the actual or intended occupancy of such tenant under the Hyatt Lease; 

  

	 	(2)	(a) any lease of the Contingent ROFO Space unless the Minimum Occupancy Requirement for Contingent ROFO Rights is satisfied, or (b) if and for so long as the Minimum Occupancy
Requirement for Contingent ROFO Rights is satisfied, any Lease of the Contingent ROFO Space effected pursuant to Paragraph 35(C)(viii); 

  

	 	(3)	any lease of the Highest ROFO Space effected pursuant to Paragraph 35 (C)(ix); or 

  

 10 

	 	(4)	any lease of space effected pursuant to the exercise by the tenant thereunder of any expansion right or option (which phrase, as used in this Paragraph 35(E), shall include any firm
option, right of refusal or right of first offer) set forth in (a) the Hyatt Lease or (b) the Goldman Lease, in each case prior to any amendment thereof (collectively, the “Permitted Superior Expansion Rights”), subject,
in each case, to Tenant’s Expansion Options set forth in Paragraph 35(B); or 

  

	 	(5)	any lease to Tenant. 

 Landlord represents and warrants to
Tenant that attached hereto as Exhibit PSER One is a true and correct copy of the provisions of the Hyatt Lease and Goldman Lease containing the Permitted Superior Expansion Rights, excluding the portion of such provisions setting forth the
rent payable thereunder. 
 The term “Permitted Expansion” means the leasing by any tenant of the Initial ROFO Space of
additional space in the Building pursuant to the exercise by such tenant of any expansion right or right of first offer provided in such tenant’s lease of Initial ROFO Space, as originally entered into, so long as, in either case, such
additional space (i) is contiguous to the then originally demised Initial ROFO Space premises leased by such tenant, and (ii) contains considering all expansion and rights of first offer, in the aggregate, no more than twenty-five percent
(25%) of the Initial ROFO Space premises initially demised by such lease as originally entered into. 
 The term “Permitted
Renewal” means the renewal of the term of any lease in the Initial ROFO Space pursuant to the exercise by the applicable tenant of any extension or renewal option provided in such tenant’s lease, as originally entered into, so long as
the total of all such extension or renewal terms are no longer than fifty percent (50%) of the initial term of such tenant’s lease, as originally entered into. 
 (ii) Landlord may, from time to time, give one or more Offer Notices. The term “Offer Notice” means a notice: 

 

	 	(1)	referring to this Paragraph 35(C); 

  

	 	(2)	describing the premises to which the notice relates (the “Offer Space”) and, if the Offer Space includes a portion less than all of the Rentable Area of any floor,
including a floor plan of such floor with such portion cross-hatched; 

  

	 	(3)	 setting forth the date upon which Landlord reasonably believes, on the basis of written agreements then in effect, that it will be able to deliver to Tenant vacant
possession thereof in the condition required by this Paragraph 35(C) (the “Scheduled Offer Space Delivery Date”) which, unless the Offer Space is Existing Recapture Space 

  

 11 

	 	 
or the Offer Space has never been leased, shall be a single date that is no earlier than earlier of (a) two (2) months after such space becomes
available because of prior tenant default and surrender if the Offer Space comprises less than a full floor, and (b) in all other cases, four (4) months, nor, in the case of Offer Space that is one full floor or less, later than fifteen
(15) months (it being understood that there is no limit to the later date if the Offer Space exceeds more than one full floor) after the date of such Offer Notice; 

  

	 	(4)	setting forth Landlord’s good faith opinion of the Current Market Rate of the Offer Space; and 

  

	 	(5)	if all or any portion of such Offer Space is subject to a Permitted Superior Expansion Right, so stating and identifying the lease containing such Permitted Superior Expansion
Right, which shall be either the Hyatt Lease or the Goldman Lease, and setting forth (i) all or such portion of the Offer Space that is subject to such Permitted Superior Expansion Right (including, if less than all of such Offer Space on a
floor, a floor plan showing the same), and (ii) the date upon which Landlord is required, if such Permitted Superior Expansion Right is exercised, to deliver all or such portion of the Offer Space to the holder of such Permitted Superior
Expansion Right (the “Permitted Superior Expansion Right Delivery Date”). 

 Each Offer Notice shall
constitute (a) an offer by Landlord to lease the Offer Space covered thereby to Tenant on the terms set forth in this Paragraph 35(C), and (b) a representation by Landlord that to, the best of its knowledge after due inquiry, all
leases covering any of such Offer Space have expired or been terminated or, pursuant to the terms thereof or other written agreements then in effect, or will expire or terminate with respect to such Offer Space on or prior to the Scheduled Offer
Space Delivery Date set forth in the Offer Notice. 
 If pursuant to the provisions of any lease other than this Lease (a “Recapture
Provision”) Landlord becomes entitled to recapture any space in the Building in connection with a proposed assignment or sublease (the “Existing Recapture Space”), then Landlord shall, within five (5) Business Days of
its receipt of the notice from the tenant entitling Landlord to recapture, give to Tenant an Offer Notice with respect to such space. Such Offer Notice (a “Recapture Offer Notice”) shall provide, in addition to the information
required by the foregoing provisions of this Paragraph 35(C)(ii) to be included therein, (a) that it relates to space that Landlord is entitled to recapture, (b) the last day upon which Landlord is permitted by the terms of the
applicable lease to exercise its recapture right (the “Landlord’s Exercise Deadline Date”), (c) a schedule of net base rent that such other tenant is required to pay for the Existing Recapture Space for the balance of the
term of such lease (the “Existing Recapture Space Rent”) and (d) the 

  

 12 

 
Recapture Expiration Date. The Recapture Offer Notice shall also be accompanied by a true, correct and complete copy of the applicable tenant lease for such
Existing Recapture Space as well as a copy such tenant’s notice to Landlord that gave rise to Landlord’s recapture rights. Landlord shall not waive or amend the Hyatt Lease so as to eliminate any Recapture Provision. 
 (iii) Tenant shall have the right, by notice to Landlord given within fifteen (15) Business Days of its receipt of any Offer Notice
or any Recapture Offer Notice (an “Acceptance Notice”), to lease all or, subject to subparagraph (2) below, a full-floor portion of, the Offer Space covered by such Offer Notice; except, that 
  

	 	(1)	 in case of any Recapture Offer Notice, the Acceptance Notice must be given, if at all, no later than the earlier of (i) the date provided for above in this
Paragraph 35(C)(iii), and (ii) the second (2nd) Business Day prior to
Landlord’s Exercise Deadline Date set forth in the Recapture Offer Notice; and 

  

	 	(2)	if the Offer Space or Existing Recapture Space includes a block of three or more contiguous full floors (an “Offer Space Block”), then Tenant may lease one or more
full floors of such Offer Space Block so long as (a) if Tenant elects to lease and include in its Acceptance Notice one full floor of such Offer Space Block, it shall lease and include in such Acceptance Notice either the top or bottom full
floor of such Offer Space Block, and (b) if Tenant elects to lease and include in its Acceptance Notice two or more full floors of such Offer Space Block, it shall lease and include in such Acceptance Notice a block of two or more contiguous
full floors, including either the top or bottom floor of such Offer Space Block. 

 Any Offer Space or Existing Recapture Space
as to which Tenant timely gives an Acceptance Notice is herein called an “Accepted Offer Space.” Tenant shall, in its Acceptance Notice, state whether it agrees with Landlord’s estimate of the Current Market Rate as set forth
in Landlord’s Offer Notice or Recapture Office Notice. If Tenant does not state in its Acceptance Notice that it agrees with Landlord’s estimate of the Current Market Rate, then the Current Market Rate shall be determined in accordance
with Article 36 herein. 
 Tenant’s delivery of any Acceptance Notice shall be effective only if at the time of delivery of
Tenant’s Acceptance Notice with respect to Accepted Offer Space the Expansion Conditions (as set forth in Subparagraphs 35(B)(vi)(1), (2), and (3)) shall be satisfied. 
  

 13 

 (iv) If Tenant timely delivers an Acceptance Notice then (i) on the Scheduled Offer
Space Delivery Date, Landlord shall deliver to Tenant (a) any Accepted Offer Space (that has not been previously improved for the occupancy of an office tenant) with all Required Landlord Work therein completed in broom clean “as is”
condition and (b) any Accepted Offer Space that has been previously improved for the occupancy of an office tenant with all Landlord’s Required Work therein completed and remaining, ordinary wear and tear excepted, and in all other
respects in the physical condition required by the prior tenant’s lease for surrender of such space and (ii) the Accepted Offer Space shall be included in the Premises upon the same terms, covenants and conditions as are applicable to the
existing Premises, except to the extent, if any, otherwise provided below. 
 (v) The term of the letting of the Accepted
Offer Space shall expire on the Expiration Date, and the Accepted Offer Space shall be included within Tenant’s Renewal Options set forth in Paragraph 35(F) hereof; except, that, notwithstanding anything set forth in this Article 35
to the contrary, 
  

	 	(1)	with respect to the Contingent ROFO Space, if the Accepted Offer Space or any portion thereof is subject to a Permitted Superior Expansion Right, then the term of the letting with
respect to such Accepted Offer Space or portion thereof shall expire on the earlier of (x) the Expiration Date, and (y) the day preceding the Permitted Superior Expansion Right Delivery Date. 

  

	 	(2)	if such Accepted Offer Space or any portion thereof is located on the floor(s) that any Expansion Space is located on and, at the time of Tenant’s giving of the Acceptance
Notice with respect thereto, the applicable Expansion Option shall not have lapsed without exercise (such space being herein called “Encumbered Accepted Offer Space”), then the term of the letting with respect to such Encumbered
Accepted Offer Space or portion thereof (the “Encumbered Offer Term”) shall expire on the relevant Expansion Target Date, or if Landlord has exercised its rights under Paragraph 35(B)(viii) prior to Tenant’s Acceptance
notice for such space, the applicable Extended Effective Date, and 

  

	 	(3)	 if (i) the Accepted Offer Space is not Existing Recapture Space, (ii) the applicable Expiration Date is less than three (3) years after the
Acceptance Notice and more than twenty-one (21) months before such Expiration Date and (iii) Tenant has not irrevocably exercised a Final Renewal Option that would extend the Term beyond such three (3) year period, then the term of
this Lease for such Accepted Offer Space shall expire on the later of (x) five 

  

 14 

	 	 
(5) years following the Accepted Offer Space Rent Commencement Date and (y) the Expiration Date, as may be extended, from time to time, pursuant to
the Renewal Options set forth in Paragraph 35(F) hereof. In the event that Tenant fails to exercise any of the Renewal Options, and is no longer entitled to exercise any such Renewal Options, then the rights of first offer contained in this
Paragraph 35(C) shall lapse and be no longer in effect. 

  

	 	(4)	if (i) the Accepted Offer Space is Existing Recapture Space, and (ii) the term of the prior lease to which the Accepted Offer Space relates (the “Recapture
Lease”) expires on a date (the “Recapture Expiration Date”) that is after the Expiration Date, then the term of this Lease for the Existing Recapture Space shall expire on the later of: (x) the Recapture Expiration
Date and (y) the Expiration Date, as may be extended, from time to time, pursuant to Paragraph 35(F) of this Lease. In the event that Tenant fails to exercise any of the Renewal Options, and is no longer entitled to exercise any such
Renewal Options, then the rights of first offer contained in this Paragraph 35(C) shall lapse and be no longer in effect. 

  

	 	(5)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses with respect to such Accepted Offer Space shall commence to accrue and be payable upon the earlier of (such
earlier date being herein called the “Offer Space Rent Commencement Date”): 

  

	 	(a)	the date that is one hundred twenty (120) days after the later of (i) the date Landlord actually tenders possession of the Accepted Offer Space to Tenant in the condition
required by Paragraph 35(C)(iv), and (ii) the Scheduled Offer Space Delivery Date; and 

  

	 	(b)	the date Tenant commences use of the Accepted Offer Space for the ordinary conduct of its business; 

  

	 	(6)	The amount of Net Rent with respect to the Accepted Offer Space shall be equal to: 

  

	 	(a)	if the Accepted Offer Space is not Existing Recapture Space, then (i) if Tenant in the Acceptance Notice agreed with Landlord’s estimate of the Current Market Rate set
forth in the applicable Offer Notice, the Current Market Rate so set forth, or (ii) otherwise, the Current Market Rate as determined pursuant to Article 36; and 

  

 15 

	 	(b)	if such Accepted Offer Space is Existing Recapture Space and is not the Highest ROFO Space, then the greater of (i) the Current Market Rate of the Accepted Offer Space,
determined either by Tenant having agreed in the Tenant’s Acceptance Notice with Landlord’s estimate of the Current Market Rate set forth in the Offer Notice, or determined pursuant to Article 36, and (ii) the Existing Recapture
Space Rent; except, that if the expiration date for Existing Recapture Space set forth in the Recapture Lease is before the Expiration Date, then from and after said expiration date of the Recapture Lease until the expiration of the Term, Net Rent
with respect to such Accepted Offer Space shall be at the Current Market Rate as previously agreed to between the parties or determined pursuant to Article 36; and 

  

	 	(c)	if such Accepted Offer Space is Highest ROFO Space that is also Existing Recapture Space, then from the commencement to the expiration of the Term of the letting of such space the
greatest of (i) the Current Market Rate of the Accepted Offer Space determined either by Tenant having agreed in the Acceptance Notice with Landlord’s estimate of the Current Market Rate set forth in the applicable Offer Notice, or
determined pursuant to Article 36 and (ii) an annual amount equal to the product of (x) $32.50 per square foot of Rentable Area, escalated at a rate per annum of two percent (2%) on a cumulative and compounded basis, commencing
on January 1, 2006, and on each January 1st thereafter (such compounding to continue until the Expiration Date) and (y) the number of square feet of Rentable Area in such Accepted Offer Space; except, that if the expiration date of
the Recapture Lease is before the Expiration Date, then from and after said expiration date of the Recapture Lease to the expiration of the Term, Net Rent with respect to such Accepted Offer Space shall be at the Current Market Rate as previously
agreed to between the parties or determined pursuant to Article 36. 

  

 16 

	 	(7)	The Rentable Area of the Premises shall be increased by the Rentable Area of the Accepted Offer Space. 

  

	 	(8)	Tenant’s Pro Rata Share shall be increased to reflect the Rentable Area of the Accepted Offer Space, effective as of the relevant Offer Space Rent Commencement Date.

  

	 	(9)	Solely with respect to Encumbered Accepted Offer Space covering the full floor of the applicable Expansion Space, Tenant shall have the right to cause Landlord to make an early
advance to Tenant of the Expansion Allowance applicable to such space. Such Expansion Allowance shall be used and disbursed in accordance with the provisions and procedures set forth in Paragraph 16 of the Workletter, so long as Tenant
exercises the applicable Expansion Option in the Acceptance Notice. During the Encumbered Offer Term, if Tenant has exercised the Expansion Option, Tenant shall pay interest on the amount of the Expansion Allowance at a rate per annum equal to
9% per annum commencing on the first day of the first month following the Accepted Offer Space Rent Commencement Date and continuing on the first day of each month thereafter until the Expansion Space Rent Commencement Date.

 Following Tenant’s delivery of an Acceptance Notice and the determination of the Current Market Rate with respect to
the Accepted Offer Space covered thereby, and within thirty (30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually, acceptable supplement to this Lease confirming the leasing of the
Accepted Offer Space pursuant hereto and the terms and conditions of such leasing provided for herein. The failure or refusal of either party to do so, however, shall not affect the validity of the leasing of the Accepted Offer Space in accordance
with the terms hereof. 
 (vi) So long as when Landlord gives an Offer Notice or Recapture Offer Notice it
is entitled, on the basis of written agreements then in effect, to possession of the Offer Space or Recapture Offer Space no later than the Scheduled Offer Space Delivery Date set forth therein, Landlord shall not be deemed to be in default under
this Lease if it is unable to deliver any Accepted Offer Space on such Scheduled Offer Space Delivery Date due solely to the failure of any tenant or any of its subtenants that may be in occupancy to have vacated it by the time in question. In
addition to the foregoing, Landlord agrees that for each day after the sixtieth (60th) day following the relevant Scheduled Office Space Delivery Date that Landlord fails to deliver to Tenant the Accepted Offer Space, Tenant shall be entitled to an abatement of Rent commencing upon the relevant Offer Space Rent
Commencement Date equal to one (1) day’s Rent otherwise payable with respect to any such Accepted Offer Space. In addition, if Landlord fails to deliver possession of any such Accepted Offer Space in the condition required by 

  

 17 

 
Paragraph 35(C)(iv) by the 90th day after the Scheduled Offer Space Delivery Date, then Tenant shall have the option, by written notice to Landlord given at any
time prior to the delivery to Tenant of the Accepted Offer Space in the condition required by Paragraph 35(C)(iv), to rescind its Acceptance Notice, in which event Landlord shall have no liability to Tenant on account of such failure timely to
deliver (except that Landlord shall not be released from such liability if Landlord breached its covenants and representations set forth in Paragraph 35(C)(ii) and (iv). Landlord will use commercially reasonable efforts timely to regain
possession of such Accepted Offer Space, including the prosecution of litigation against any occupant of such space. 
 (vii)
If in response to any Offer Notice or Recapture Offer Notice Tenant fails to timely deliver an Acceptance Notice (or the same is rescinded pursuant to Paragraph 34(C)(vi)) with respect to the Offer Space that is the Initial ROFO Space, then
during the two hundred seventy (270) day period commencing ten (10) Business Days after Tenant’s receipt of Landlord’s Offer Notice (or commencing on the effective date of such rescission under Paragraph 35(C)(vi) above, as
applicable), Landlord shall be permitted to lease all or any portion of said Initial ROFO Space covered by such Offer Notice or Recapture Offer Notice to any person or persons on any terms acceptable to Landlord in its sole discretion for delivery
no earlier than the Scheduled Offer Space Delivery Date set forth in such Offer Notice or Recapture Offer Notice (subject, however, to Tenant’s rights, if any, under Paragraph 35(B), if applicable, and Tenant’s rights, if any, under
Paragraph 35(C)(i) with respect to Permitted Renewals and Permitted Expansions)). Notwithstanding the foregoing, if any such Offer Space that is Initial ROFO Space is leased, as permitted, then following the expiration or earlier
termination of such lease (except as permitted by the other provisions of Paragraph 35(C)(i), if applicable), Landlord may not subsequently lease such Offer Space except pursuant to this Paragraph 35(C)(vii) based upon a subsequent Offer
Notice given to Tenant with respect thereto. If a lease for such Offer Space is not fully executed within the foregoing 270-day period, then the Landlord again shall be prohibited from leasing such Offer Space other than pursuant to the terms of
this Paragraph 35(C) based upon a subsequent Offer Notice given to Tenant with respect thereto. The provisions of this Paragraph 35(C)(vii) shall not be applicable to the Highest ROFO Space and the Contingent ROFO Space. 

(viii) If Mayer Brown Rowe & Maw or any Law Successor occupies more than 550,000 square feet of Rentable Area in the Building
under the terms of this Lease (the “Minimum Occupancy Requirement for Contingent ROFO Rights”), then for so long as Mayer Brown Rowe & Maw or any such Law Successor maintains occupancy of Rentable Area in the Building under
the terms of this Lease in excess of the Minimum Occupancy Requirement for Contingent ROFO Rights, it shall be entitled to exercise the rights under this Paragraph 35(C) with respect to any portion of the Contingent ROFO Space that
thereafter becomes available for lease, subject to any Permitted Superior Expansion Rights therein. If in response to any Offer Notice, Tenant fails to timely deliver an Acceptance Notice (or the same is rescinded pursuant to Paragraph 35(C)(vi))
with respect to 

  

 18 

 
Offer Space that is Contingent ROFO Space, Landlord shall be permitted to lease all or any portion of said Contingent ROFO Space to any person or persons on
terms acceptable to Landlord in its sole discretion for delivery no earlier than the Scheduled Offer Space Delivery Date set forth in such Offer Notice. 
 (ix) If in response to any Offer Notice, Tenant fails to timely deliver an Acceptance Notice (or the same is rescinded pursuant to Paragraph 35(c)(vi)) with respect to Offer Space that is Highest ROFO Space, Landlord
shall be permitted to lease all or any portion of such Highest ROFO Space to any person or persons (subject to Article 30) on terms acceptable to Landlord in its sole discretion for delivery no earlier than the Scheduled Offer Space Delivery Date
set forth in such notice. 
 For all purposes of this Lease, “Current Market Rate” is as defined on Exhibit CMR
attached hereto and made a part hereto. 
 (D) Tenant’s Pre-Occupancy Option to Reduce the Premises. Subject
to Subparagraph (iii) below, Tenant shall have two options (each, a “Pre-Occupancy Contraction Option”) to reduce the Premises by an area of space (the “Pre-Occupancy Contraction Space”), at Tenant’s
option, equal to (x) in the case of the first Pre-Occupancy Contraction Option, the entire 34th floor of the Building, and (y) in the case of the second Pre-Occupancy Contraction Option, (1) if the first Pre-Occupancy Contraction
Option shall have been timely exercised by June 30, 2003, the entire 35th floor of the Building, and (2) if the first Pre-Occupancy Contraction Option shall have not been exercised, one-half ( 1/2) full floor of space or one (1) full floor of space located on the
34th floor of the Building, upon the following terms and conditions:

 (i) A Pre-Occupancy Contraction Option shall be effective upon Tenant’s exercise thereof (the
“Pre-Occupancy Contraction Effective Date”); 
 (ii) Tenant shall give Landlord written
notice of Tenant’s election to exercise the (a) first Pre-Occupancy Contraction Option on or before June 30, 2003, and (b) the second Pre-Occupancy Contraction Option on or before December 31, 2003, which notice concerning
the second Pre-Occupancy Contraction Option shall identify (if Tenant has not exercised the first Pre-Occupancy Contraction Option) whether Tenant is contracting the Premises on the thirty-fourth (34th) floor of the Building by one-half ( 1/2) floor or by one (1) full floor, pursuant to such contraction option. If
said contraction is by one-half ( 1/2) floor, then the half floor
so remaining shall be located on the eastern or western half of the floor, as designated by Tenant in its notice of exercise of its second Pre-Occupancy Contraction Option, and Tenant, at its cost and expense, shall construct the elevator lobby and
common corridor required to make the floor usable by more than one tenant to a standard of finish not less than Building standard, as established by Landlord for multi-floor tenants; and 
  

 19 

 (iii) Tenant shall not be entitled to exercise any Pre-Occupancy Contraction Option if on
the Pre-Occupancy Contraction Effective Date Tenant’s rights of possession shall have been terminated and this Lease shall not then be in full force and effect. 
 (iv) Tenant shall not be required to pay Landlord a contraction fee for the exercise of any such Pre-Occupancy Contraction Option.

 In the event Tenant properly exercises any Pre-Occupancy Contraction Option, then 
 (i) The Rentable Area of the Premises shall be decreased by the Rentable Area of the applicable Pre-Occupancy Contraction Space; and

 (v) Tenant’s Pro Rata Share shall be reduced to reflect the Rentable Area of the applicable Pre-Occupancy Contraction
Space. 
 If Tenant timely exercises a Pre-Occupancy Contraction Option, then neither Landlord nor Tenant shall have any rights, estates,
liabilities or obligations first accruing under this Lease after the Pre-Occupancy Contraction Effective Date with respect to the applicable Pre-Occupancy Contraction Space, except such rights and liabilities as are otherwise expressly provided by
the terms of this Lease. Following Tenant’s exercise of any Pre-Occupancy Contraction Option, and within thirty (30) days following written request by either Landlord or Tenant, Landlord and Tenant shall enter into a mutually acceptable
supplement to this Lease confirming the terms, conditions and provisions applicable to such Pre-Occupancy Contraction Option as determined in accordance herewith. The failure or refusal of either party to execute such a supplement shall not affect
the validity of the elimination of the applicable Pre-Occupancy Space from this Lease in accordance with the proper exercise of the applicable Pre-Occupancy Contraction Option. 
 (E) Tenant’s Five Year Option to Reduce the Premises. Subject to clauses (ii), (iv), and (viii) below,
Tenant shall have the one-time option (the “Five Year Contraction Option”) to reduce the Premises by an area (the “Five Year Contraction Space”), at Tenant’s option, equal to either: (i) (a) one-half
( 1/2) full floor of space, (b) one full floor of space or
(c) one and one-half (1 1/2) full floors of space if
Tenant has not exercised the first Pre-Occupancy Contraction Option, but has exercised the second Pre-Occupancy Contraction Option with respect to one-half ( 1/2) floor of space, or (ii) one-half ( 1/2) full floor of space or one (1) full floor of space if, in each case,
Tenant has not exercised second Pre-Occupancy Contraction Option, in each of the foregoing cases set forth in subclauses (i) and (ii), such Five Year Contraction Space shall be (x) the one-half ( 1/2) of the 34th floor of the Building, if on the date of Tenant’s exercise of the Five Year Contraction Option Tenant is only occupying
one-half ( 1/2) of the 34th Floor as result of Tenant’s prior exercise of the second Pre-Occupancy Contraction Option with respect to
one-half ( 1/2) floor and Tenant also exercises the Five Year
Contraction Option with respect to one-half ( 1/2) floor, and
(y) otherwise, the space on the lowest non-transfer floor (32 and 33 being the transfer floors) of the Premises as selected and designated by Tenant as of the date of Tenant’s exercise of such Five Year Contraction Option, upon and subject
to the following terms and conditions: 
 (i) The
Five Year Contraction Option is to be effective as of the fifth (5th) anniversary date of the Commencement Date of the Lease (i.e., the first day of the sixty-first (61st) full calendar month following the Commencement Date) (the “Five Year Contraction Effective Date”); 
  

 20 

 (ii) Tenant shall not have irrevocably exercised the First Expansion Option by delivering
the Tenant’s First Expansion Notice; 
 (iii) Tenant shall give Landlord written notice of
Tenant’s election to exercise the Five Year Contraction Option not later than the first day of the forty-ninth (49th) full calendar month of the Term which notice shall identify the location of the Five Year Contraction Space to be surrendered
to Landlord pursuant to the Five Year Contraction Option; 
 (iv) On the date Tenant exercises the Five Year Contraction
Option, Tenant’s right of possession shall not have been terminated and this Lease shall then be in full force and effect; 
 (v) Tenant shall pay to Landlord a contraction fee in an amount equal to all of Landlord’s then unamortized (at an interest factor of 8%) costs in connection with the leasing to Tenant of the Five Year Contraction Space, which shall be
limited to the commission paid to Broker and the Allowance ratably allocated thereto, plus twelve (12) months’ then effective Net Rent and Additional Rent with respect to the Five Year Contraction Space (except, that all variable Operating
Expenses related to said Five Year Contraction Space (e.g., janitorial) shall be deducted from the Additional Rent for the purposes of computing said contraction fee). Such contraction fee shall be payable in full upon the Five Year Contraction
Option Effective Date; 
 (vi) The exercise of the Five Year Contraction Option shall not affect or diminish Tenant’s
obligations to pay Additional Rent with respect to the Shared Facilities; 
 (vii) If following
Tenant’s exercise of the Five Year Contraction Option, Tenant’s Premises include one-half ( 1/2) of a full floor and excludes the remaining one-half ( 1/2) of that full floor, then Tenant, at its cost and expense, shall construct, to a standard of finish not less than Building standard as established by Landlord for multi-floor tenants, a common
corridor required to make the Five Year Contraction Space on such floor leasable to another tenant; and 
 (viii) Tenant shall not have the right to exercise the Five Year Contraction Option in the event Tenant has exercised both Pre-Occupancy Contraction Options. 
  

 21 

 In the event Tenant properly exercises the Five-Year Contraction Option, then 
 (ii) The Rentable Area of the Premises shall be decreased by the Rentable Area of the Five-Year Contraction Space; and 
 (ix) Tenant’s Pro Rata Share shall be reduced to reflect the Rentable Area of the Five-Year Contraction Space. 
 If Tenant timely exercises the Five Year Contraction Option, then the Term with respect to the portion of the Five Year Contraction Space shall terminate
effective as of the Five Year Contraction Effective Date. Rent for the terminated portion of the Premises shall be paid through and apportioned as of the Five Year Contraction Effective Date and neither Landlord nor Tenant shall have any rights,
estates, liabilities or obligations first accruing under this Lease after the Five Year Contraction Effective Date with respect to such contracted area, except such rights and liabilities that are otherwise expressly provided in this Lease.

 Following Tenant’s exercise of the Five-Year Contraction Option, and within thirty (30) days following written request by either
Landlord or Tenant, Landlord and Tenant shall enter into a mutually acceptable supplement to this Lease confirming the terms, conditions and provisions applicable to such Five-Year Contraction Option as determined in accordance herewith. The failure
or refusal of either party to execute such a supplement shall not affect the validity of the elimination of the Five-Year Contraction Space from this Lease in accordance with the proper exercise of the Five-Year Contraction Option. 
 (F) Renewal. 
 (i)
Tenant shall have two (2) options to extend the Term for five (5) years each (the first five (5) year extension option is referred to as the “First Renewal Option”, the second five (5) year option is referred to
as the “Second Renewal Option”, and the First Renewal Option and the Second Renewal Option are collectively referred to as the “Renewal Options”)), upon the terms and conditions contained herein, including without
limitation, the payment of Tenant’s obligations with respect to Shared Facilities and Tenant’s Pro Rata Share of Taxes and Operating Expenses, determined on the same basis as set forth in Article 3 of this Lease, and subject to any
changes in the Rentable Area of the Building and the Premises (pursuant to Paragraph 1(B) above); except, that the Net Rent for such Renewal Options shall be at the Current Market Rate for the applicable period. 
 (ii) Upon written notice delivered to Landlord not later than thirty-six (36) full calendar months prior to the Expiration Date, in
the case of the First Renewal Option, and thirty-six (36) full calendar months prior to expiration of the first renewal term, in the case of the Second Renewal Option, Tenant shall have the one-time right (in the case of each Renewal Option) to
notify Landlord of Tenant’s election to reduce the portion of the Premises with respect to which such Renewal Option may be 

  

 22 

 
exercised by identifying in said notice that portion of the Premises subject to the Renewal Option (said portion being herein called the “Renewal
Premises”), so long as such Renewal Premises as designated by Tenant consists solely of (a) the Premises as constituted on the Commencement Date (as the same may have been reduced by Tenant’s exercise of the Five Year Contraction
Option) (the “Adjusted Initial Premises”), (b) at Tenant’s election, specified in said notice, any additional part of the Premises vertically contiguous to the Adjusted Initial Premises at the time of such Renewal Premises
notice and (c) at Tenant’s election, specified in said notice one or more full floors of the Building constituting the balance of the Premises that are next closest (but not vertically contiguous) to the then lowest portion of the Premises
described in clauses (a) or (b) above. If Tenant exercises its right under this Paragraph 35(F)(ii) to cause a Renewal Option to apply to less than the entire Premises, then during the term of such Renewal Option Tenant’s
rights under this Paragraph 35(C) shall not apply to the portion of the Premises so excluded from the Renewal Premises that Landlord leases to third parties for a term commencing during the Renewal Option Period, including any renewals of
such leases pursuant to the terms thereof. 
 (iii) If Tenant desires to initially exercise the First Renewal Option or Second
Renewal Option, as the case may be, Tenant shall deliver Landlord an initial non-binding notice (the “Initial Renewal Notice”) of Tenant’s intent to exercise either of said Renewal Options no earlier than the sixtieth
(60th) and no later than the twenty-seventh (27th) month prior to the Expiration Date, as may have been theretofore extended. Following Tenant’s delivery of the Initial Renewal Notice, the Current Market Rate shall be determined in
accordance with Article 36 hereof. In all events, Tenant reserves the right to rescind its Initial Renewal Notice by so notifying Landlord prior to delivery of the Final Renewal Notice. 
 (iv) If Tenant desires to irrevocably exercise its First Renewal Option or Second Renewal Option, as the case may be, Tenant shall deliver
to Landlord Tenant’s final binding written notice of its exercise of the First Renewal Option or Second Renewal Option, as the case may be, (the “Final Renewal Notice”), upon the later of (a) twenty-one (21) full
calendar months prior to the end of the Expiration Date, as may have been theretofore extended, and (b) five (5) Business Days following the determination of the Current Market Rate. 
 (v) Tenant shall not be entitled to exercise a Renewal Option if on the date Tenant exercises such Renewal Option Tenant is (a) then
in monetary or material non-monetary Default, or (b) if this Lease or Tenant’s right of possession has been terminated, or (c) if this Lease is not in full force and effect on said date. Tenant shall not be entitled to the Second
Renewal Option unless Tenant has exercised the First Renewal Option. 
  

 23 

 (vi) If Tenant fails to timely deliver the Initial Renewal Notice or the Final Renewal
Notice, then Tenant will be deemed to have waived the applicable Renewal Option. 
 (vii) Following Tenant’s exercise of
a Renewal Option and the determination of the Net Rent for the respective renewal period, at the request of either party hereto and within thirty (30) days after such request, Landlord and Tenant shall enter into a supplement to this Lease
confirming the terms, conditions and provisions applicable to the related Renewal Period as determined in accordance herewith. Failure of either party or refusal of either party to execute a supplement shall not affect the validity of the exercise
of the Renewal Option. 
 (G) Tenant’s Right to Lease from Building Tenants. Notwithstanding any provision of any lease or other
agreement that may give Landlord the right to withhold consent to any sublease to Tenant, or any assignment of any lease to Tenant, or any right to recapture (by any means) the premises proposed to be subleased to Tenant or the premises covered by
any lease proposed to be assigned to Tenant, Landlord agrees that (i) it shall consent to any such sublease or assignment and shall not exercise any such recapture right, unless required to do so under any Permitted Superior Expansion Right,
and (ii) Tenant may furnish a copy of this Paragraph 35(G) to any Building tenant, and any such Building tenant may rely thereon. 
 (H) Assignment/Delegation of Tenant’s Rights. Tenant’s rights and options under this Article 35 and the following Article 36 may be exercised solely by an assignee of this Lease or any Major Transferee to whom
Tenant has assigned or delegated such rights, if Tenant delivers to Landlord a notice advising Landlord with specificity of any such assignment or delegation and the duration thereof, together with the instrument so assigning or delegating such
rights. 
 (i) If the Premises shall include some but not all of the office areas on a floor and thereafter shall come to
include all of the office areas on any floor, then (a) the premises shall be deemed also to include the elevator lobby, common corridor and other areas, which, on a divided floor, would constitute Common Area, and (b) the Rentable Area of
the Premises on such floor shall be calculated as if Tenant had leased all of such floor concurrently as a single floor. 
 (ii) No provision of this Article 35 that authorizes Landlord to lease any portion of the Building to any third party shall include, on any divided floor, the portion thereof required for Common Areas.

	 	(2)	Net Rent and Additional Rent in respect of Taxes and Operating Expenses, with respect to the Remaining 17th Floor Premises, shall commence to be payable on the date (the

	 	(a)	the date which is one hundred twenty (120) days after the later of (x) the date on which Landlord actually tenders possession of the Remaining 17th Floor Premises to

Landlord or Tenant, Landlord and Tenant shall enter into a mutually-acceptable supplement to this Lease confirming the leasing of the Remaining 17th Floor Premises pursuant hereto and the terms and conditions of such leasing provided for herein. The
failure or refusal of either party to do so, however, shall not affect the validity of the leasing of the Remaining 17th Floor Premises. 
 (iv) Landlord may lease the Remaining 17th Floor Premises, or portions thereof, from time to time to third parties so long as such space is scheduled to be available to be leased to Tenant pursuant to Tenant’s
Remaining 17th Floor Premises Expansion Option. So long as Landlord has not granted any person rights which conflict with Tenant’s Remaining 17th Floor Premises Expansion Option, Landlord shall have no liability to Tenant, and Landlord shall
not be deemed to be in default under this Lease, if it is unable to deliver the Remaining 17th Floor Premises to Tenant on the Remaining 17th Floor Premises Expansion Option Scheduled Delivery Date due solely to the failure of any tenant or any of
its subtenants to have vacated it by the time in question. If, however, Landlord fails to deliver possession of the Remaining 17th Floor Premises in the condition required by Paragraph 35(N)(iii) by the date which is the 90th day after the
Remaining 17th Floor Premises Expansion Option Scheduled Delivery Date (as such date is extended by Unavoidable Delays), Tenant shall

(except that Landlord shall not be released from such liability if it shall have granted any person rights which conflict with Tenant’s Remaining 17th Floor Premises Expansion Option) and shall have no further obligation to deliver the
Remaining 17th Floor Premises, or (b) to lease from Landlord on a temporary basis and at the same rent other space in the Building, to the extent available, comparable in size to the Remaining 17th Floor Premises. Landlord will use commercially
reasonable efforts to regain possession of the Remaining 17th Floor Premises as promptly as reasonably possible, including the prosecution of litigation against any occupant of such space. 
 From and after the Effective Date, the term “Expansion Option” shall be deemed to include the Remaining 17th Floor Premises Expansion
Option, the term “Expansion Option Rent Commencement Date” shall be deemed to include the Remaining 17th Floor Premises Expansion Option Rent Commencement Date, and the term “Expansion Premises” shall be deemed to
include the Remaining 17th Floor Expansion Premises.

second grammatical paragraph thereof in its entirety and substituting the following therefor:

illegal, invalid or unenforceable, the remaining provisions hereof shall remain in full force and effect and this Agreement shall be interpreted as if such legal, invalid or unenforceable provision did not exist herein.

adopted and confirmed. 
 23. Limitation on Landlord’s Liability. It is expressly understood and agreed by Tenant that none of
Landlord’s covenants, undertakings or agreements are made or intended as personal covenants, undertakings or agreements by Landlord, and any liability of Landlord for damages or breach or nonperformance by Landlord or otherwise arising under or
in connection with this Agreement or the Lease or the relationship of Landlord and Tenant hereunder, shall be collectible only out of Landlord’s interest in the Property (or if Landlord is the beneficiary of a land trust, Landlord’s right,
title and interest in such land trust), in each case as the same may then be encumbered, and no personal liability is assumed by, nor at any time may be asserted against, Landlord, its members or its other owners, direct or remote, all such
liability, if any, being expressly waived and released by Tenant. The limitations of liability of Landlord contained herein shall apply equally to and inure to the benefit of the Landlord Protected Parties. Tenant further expressly understands and
agrees that if any instrument involving the Building is executed by Landlord’s agent (“Landlord’s Agent”) on behalf of Landlord, then Landlord’s Agent executes such instrument, not in its own right but solely as
Landlord’s Agent and that nothing 

  

 9 

 
in this Lease shall be construed as creating any liability whatsoever against such Landlord’s Agent, its owners, direct and remote, and their respective
directors, officers or employees and in particular, without limiting the generality of the foregoing, there shall be no liability of Landlord’s Agent to pay any indebtedness or sum accruing thereunder, or to perform any covenant or agreement
whether expressed or implied therein contained, it being agreed that Landlord shall have sole responsibility therefor. 
 IN WITNESS WHEREOF,
the parties hereto have executed this First Amendment to Lease as of the day and year first above written.

agrees that if any instrument involving the Building is executed by Landlord’s agent (“Landlord’s Agent”) on behalf of Landlord, then Landlord’s Agent executes such instrument, not in its own right but solely as
Landlord’s Agent and that nothing in this Lease shall be construed as creating any liability whatsoever against such Landlord’s Agent, its owners, direct and remote, and their respective directors, officers or employees and in particular,
without limiting the generality of the foregoing, there shall be no liability of Landlord’s Agent to pay any indebtedness or sum accruing thereunder, or to perform any covenant or agreement whether expressed or implied therein contained, it

3(B)(vii) of the Original Lease, as modified by Paragraph 3 of the First Amendment. 
 g. References to Premises.
Except as expressly set forth herein to the contrary, during the 8th Floor Premises Term, all references in the Lease and this Agreement to “Premises” shall be deemed to include the Existing Premises and the 8th Floor Premises.

  

 2 

 h. No Subletting. Tenant shall not (i) sublet the 8th Floor Premises or any
part thereof, or (iii) permit the use of the 8th Floor Premises by any parties other than Tenant or its employees (each of the foregoing being hereinafter referred to as an “8th Floor Premises Transfer”). Any 8th Floor Premises
Transfer shall be null, void and of no effect and shall constitute a Default under this Agreement and the Lease. 
 i.
Expiration of 8th Floor Premises Term. At the expiration of the 8th Floor Premises Term, Tenant shall surrender possession of the 8th Floor Premises in accordance with the terms and provisions of Article 13 of the Lease. If Tenant fails to
surrender possession of the 8th Floor Premises as aforesaid by the 8th Floor Premises Termination Date, Tenant shall be deemed a holdover tenant in the 8th Floor Premises as contemplated by and consistent with Article 14 of the Lease. From and after
the 8th Floor Premises Termination Date (or such later date on which Tenant actually surrenders possession of the 8th Floor Premises), the Net Rent and Tenant’s Pro Rata Share shall be appropriately adjusted. 
 j. Furniture. As of the Agreement Effective Date, the 8th Floor Premises contains the furniture shown on the space plan attached
hereto as Exhibit C (the “Furniture”). Landlord hereby grants Tenant the right to use the Furniture during the 8th Floor Premises Term. Tenant accepts the Furniture “AS IS” and agrees to maintain the Furniture in
good condition and repair. Any furniture that replaces any of the Furniture shall become the Furniture. Upon the expiration of the 8th Floor Premises Term, Tenant shall surrender possession of the Furniture in good condition and repair, ordinary
wear and tear and damage excepted. 
 k. Shared Floor. The 8th Floor Premises comprise a part of a full floor build-out
rather than a separate, demised space of the type typically found on a multi-tenant floor of the Building. If during the 8th Floor Premises Term, Landlord leases all or any portion of the remainder of the 8th floor (the “Remainder
Premises”) to another tenant, Tenant shall reimburse Landlord, as Additional Rent, for fifty percent (50%) of the reasonable costs incurred by Landlord to construct demising walls and entrances to the 8th Floor Premises and the
Remainder Premises and common corridors on such floor, re-route and/or separate utilities (to the extent applicable) and to perform all other work as may be required to separate the 8th Floor Premises from the Remainder Premises. 
 l. Certain Definitions. As used in this Agreement, the following terms shall have the meanings ascribed to them as set forth below:

 (i) The term “8th Floor Premises Commencement Date” shall mean the date on which Landlord delivers
possession of the 8th Floor Premises to Tenant. 
  

 3 

 (ii) The term “8th Floor Premises Rent Commencement Date” shall mean the
date that is the earlier to occur of (x) July 1, 2008, and (y) the date on which Tenant occupies the 8th Floor Premises for the purpose of conducting business therein. 
 3. Substitution of 8th Floor Premises. If at any time during the 8th Floor Premises Term, Landlord receives a bona fide third
party offer to lease all or any portion of the 8th floor Premises, Landlord, upon ten (10) days prior notice, may substitute for the 8th Floor Premises other premises on the 8th floor of the Building containing a comparable number of
workstations (the “Alternate 8th Floor Premises”). Landlord, at Landlord’s sole cost and expense, shall install phone and data cabling in the Alternate 8th Floor Premises comparable to such cabling installed in the 8th Floor
Premises. 
 4. Electrical Service. Notwithstanding anything to the contrary contained in Paragraph 6(D) of the Lease, as modified by
Paragraph 4 of the Second Amendment, usage of electricity servicing the 8th Floor Premises shall be separately metered and payable by Tenant directly to the utility service provider thereof. 
 5. Integration of Lease and Controlling Language. This Agreement and the Lease shall be deemed to be, for all purposes, one instrument. In the
event of any conflict between the terms and provisions of this Agreement and the terms and provisions of the Lease, the terms and provisions of this Agreement, in all instances, shall control and prevail. 
 6. Severability. If any provision of this Agreement or the application thereof to any person or circumstance is or shall be deemed illegal,
invalid or unenforceable, the remaining provisions hereof shall remain in full force and effect and this Agreement shall be interpreted as if such legal, invalid or unenforceable provision did not exist herein. 
 7. Entire Agreement. This Agreement and the Lease contain the entire integrated agreement between the parties respecting the subject matter of
this Agreement and the Lease and supersede all prior and contemporaneous understandings and agreements, other than the Lease, between the parties respecting the subject matter of this Agreement and the Lease. There are no representations,
agreements, arrangements or understandings, oral or in writing, between or among the parties to this Agreement relating to the subject matter of this Agreement or the Lease which are not fully expressed in this Agreement and the Lease, and no party
hereto has relied upon any other such representations, agreements, arrangements or understandings. The terms of this Agreement and the Lease are intended by the parties as the final expression of their agreement with respect to those terms and may
not be contradicted by evidence of any prior agreement or of any contemporaneous agreement. The parties further intend that no extrinsic evidence whatsoever may be introduced in any judicial proceeding involving this Agreement. 
 8. Successors and Assigns. Each provision of the Lease and this Agreement shall extend to and shall bind and inure to the benefit of Landlord and
Tenant, their respective heirs, legal representatives, successors and assigns. 
 9. Time of the Essence. Time is of the essence of
this Agreement and the Lease and each provision hereof. 
  

 4 

 10. Multiple Counterparts. This Agreement may be executed in counterparts, all of which, when
taken together, shall constitute a fully executed instrument. 
 11. Authority. Landlord and Tenant each represent and warrant that it
has full authority to execute and deliver this Agreement. 
 12. Ratification. Except as amended and modified hereby, the Lease shall
be and shall remain unchanged and in full force and effect in accordance with its terms, and, as the Lease is amended and modified hereby, the Lease is hereby ratified, adopted and confirmed. 
 13. Limitation on Landlord’s Liability. It is expressly understood and agreed by Tenant that none of Landlord’s covenants, undertakings
or agreements are made or intended as personal covenants, undertakings or agreements by Landlord, and any liability of Landlord for damages or breach or nonperformance by Landlord or otherwise arising under or in connection with this Agreement or
the Lease or the relationship of Landlord and Tenant hereunder, shall be collectible only out of Landlord’s interest in the Property (or if Landlord is the beneficiary of a land trust, Landlord’s right, title and interest in such land
trust), in each case as the same may then be encumbered, and no personal liability is assumed by, nor at any time may be asserted against, Landlord, its members or its other owners, direct or remote, all such liability, if any, being expressly
waived and released by Tenant. The limitations of liability of Landlord contained herein shall apply equally to and inure to the benefit of the Landlord Protected Parties. Tenant further expressly understands and agrees that if any instrument
involving the Building is executed by Landlord’s agent (“Landlord’s Agent”) on behalf of Landlord, then Landlord’s Agent executes such instrument, not in its own right but solely as Landlord’s Agent and that
nothing in this Lease shall be construed as creating any liability whatsoever against such Landlord’s Agent, its owners, direct and remote, and their respective directors, officers or employees and in particular, without limiting the generality
of the foregoing, there shall be no liability of Landlord’s Agent to pay any indebtedness or sum accruing thereunder, or to perform any covenant or agreement whether expressed or implied therein contained, it being agreed that Landlord shall
have sole responsibility therefor. 
 14. No Offer. Submission of this Agreement by Landlord to Tenant is not an offer to enter into
this Agreement but rather is a solicitation for such an offer from Tenant. Landlord shall not be bound by this Agreement until Landlord has executed and delivered the same to Tenant.

Premises”) to another tenant, Tenant shall reimburse Landlord, as Additional Rent, for fifty percent (50%) of the reasonable costs incurred by Landlord to construct demising walls and entrances to the Additional 8th Floor Premises and

Language. This Agreement and the Lease shall be deemed to be, for all purposes, one instrument. In the event of any conflict between the terms and provisions of this Agreement and the terms and provisions of the Lease, the terms and provisions
of this Agreement, in all instances, shall control and prevail.

 FIFTH AMENDMENT TO LEASE 
 THIS FIFTH AMENDMENT TO LEASE (this “Agreement”) is entered into as of December 22, 2008 (the “Fifth Amendment Effective
Date”), by and between FRANKMON LLC, a Delaware limited liability company (“Landlord”), and HYATT CORPORATION, a Delaware corporation (“Tenant”), with reference to the following: 
 R E C I T A L S: 
 A. Landlord and Tenant
heretofore entered into that certain amended and restated office lease dated as of June 15, 2004 (the “Original Lease”), pursuant to which Tenant leased certain premises (the “Original Premises”) on the 9th
through 16th and 46th through 48th floors of the building located at 71 South Wacker Drive, Chicago, Illinois (the “Building”). 
 B. Landlord and Tenant subsequently entered into that certain supplemental agreement dated September 1, 2006 (the “Supplemental Agreement”), pursuant to which Landlord and Tenant, among other things, confirmed certain
dates relating to Tenant’s leasing of the Premises and the number of square feet of Rentable Area contained in each of the floors that comprise a part of the Premises. 
 C. Landlord and Tenant subsequently entered into a certain First Amendment to Lease dated October 13, 2006 (the “First Amendment”),
pursuant to which, among other things, Tenant leased certain additional premises on the 17th floor of the Building (the “17th Floor Premises”) adjacent to the Original Premises. 
 D. Landlord and Tenant subsequently entered into a certain Second Amendment to Lease dated February 1, 2007 (the “Second
Amendment”), pursuant to which, among other things, Tenant leased certain additional premises on the 17th floor of the Building (the “Additional 17th Floor Premises”) adjacent to the 17th Floor Premises. 
 E. Landlord and Tenant subsequently entered into a certain Third Amendment to Lease dated June 26, 2008 (the “Third Amendment”),
pursuant to which, among other things, Tenant leased certain additional premises on the 8th floor of the Building (the “8th Floor Premises”). 
 F. Landlord and Tenant subsequently entered into a certain Fourth Amendment to Lease dated of even date herewith (the “Fourth Amendment”), pursuant to which, among other things, Tenant leased certain
additional premises on the 8th floor of the Building (the “Additional 8th Floor Premises”). The Original Premises, the 17th Floor Premises, the Additional 17th Floor Premises, the 8th Floor Premises and the Additional 8th Floor
Premises are collectively referred to herein as the “Premises.” 
 G. The Original Lease, as modified by the Supplemental
Agreement, the First Amendment, the Second Amendment, the Third Amendment and the Fourth Amendment, is herein referred to as the “Lease.” 

 H. Tenant, pursuant to Paragraph 35(J) of the Original Lease, would be obligated to surrender possession
of the entire 46th floor of the Building (the “46th Floor Space”) if Mayer Brown were to timely exercise its right to lease the 46th Floor Space pursuant to the MB 46th Floor Expansion Right. 
 I. Tenant, at the request of Diversified Financial Management Corp., Tenant’s subtenant for a portion of the 46th Floor Space pursuant to that
certain Sublease dated as of July 15, 2004, requested Landlord to seek to have Mayer Brown waive and relinquish any and all rights pursuant to the Mayer Brown Lease to lease the 46th Floor Space. 
 J. Landlord, at Tenant’s request, has caused Mayer Brown to enter into an amendment to the Mayer Brown Lease (the “Mayer Brown Lease
Amendment”), pursuant to which Mayer Brown has waived and forever relinquished any and all rights it has to the 46th Floor Space. 
 K. In conjunction with the Mayer Brown Lease Amendment, Landlord and Tenant desire to amend the Lease to remove therefrom Tenant’s obligation to surrender possession of the 46th Floor Space following an exercise by Mayer Brown of the
MB 46th Floor Expansion Right, as more particularly described below. 
 NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements herein contained, Landlord and Tenant hereby agree as follows: 
 1. Incorporation and Defined Terms. The
recital paragraphs set forth above are hereby incorporated herein as if fully set forth herein. Capitalized terms not otherwise defined herein shall have the same meanings as are ascribed to such terms in the Lease. 
 2. Elimination of Mandatory Surrender of 46th Floor. Paragraph 35(J) of the Original Lease, from and after the Fifth Amendment Effective Date, is
hereby deleted in its entirety, it being acknowledged and agreed that Landlord, from and after the Fifth Amendment Effective Date, shall have no further right to deliver to Tenant the MB 46th Floor Option Notice. All references in the Lease to the
MB 46th Floor Expansion Right, the MB 46th Floor Option Notice, the Required Contraction Effective Date, the Possible 46th Floor Replacement Premises and the 46th Floor Surrender Date shall be deemed deleted in their entirety. 
 3. Elimination of 46th Floor Replacement Option. Paragraph 35(K) of the Original Lease, from and after the Fifth Amendment Effective Date, is
hereby deleted in its entirety, it being acknowledged and agreed that Tenant, from and after the Fifth Amendment Effective Date, shall have no further right to exercise the 46th Floor Replacement Option. All references in the Lease to the 46th Floor
Replacement Option, the 46th Floor Replacement Option Scheduled Delivery Date, the 46th Floor Replacement Notice, the 46th Floor Replacement Option Rent Commencement Date, the 46th Floor Replacement Premises Allowance and the 46th Floor Replacement
Premises shall be deemed deleted in their entirety. 
  

 2 

 4. Reimbursement for Consideration Paid. Pursuant to the Mayer Brown Amendment, Landlord has
agreed to pay Mayer Brown a sum equal to Four Hundred Twenty-Five Thousand and No/100 Dollars ($425,000.00) (the “Relinquishment Consideration”) as consideration for the waiver and relinquishment by Mayer Brown of the MB 46th Floor
Expansion Right. Tenant, concurrently with Tenant’s execution and delivery of this Agreement, shall pay to Landlord a sum equal to the Relinquishment Consideration as reimbursement therefor to Landlord. 
 5. Integration of Lease and Controlling Language. This Agreement and the Lease shall be deemed to be, for all purposes, one instrument. In the
event of any conflict between the terms and provisions of this Agreement and the terms and provisions of the Lease, the terms and provisions of this Agreement, in all instances, shall control and prevail. 
 6. Severability. If any provision of this Agreement or the application thereof to any person or circumstance is or shall be deemed illegal,
invalid or unenforceable, the remaining provisions hereof shall remain in full force and effect and this Agreement shall be interpreted as if such legal, invalid or unenforceable provision did not exist herein. 
 7. Entire Agreement. This Agreement and the Lease contain the entire integrated agreement between the parties respecting the subject matter of
this Agreement and the Lease and supersede all prior and contemporaneous understandings and agreements, other than the Lease, between the parties respecting the subject matter of this Agreement and the Lease. There are no representations,
agreements, arrangements or understandings, oral or in writing, between or among the parties to this Agreement relating to the subject matter of this Agreement or the Lease which are not fully expressed in this Agreement and the Lease, and no party
hereto has relied upon any other such representations, agreements, arrangements or understandings. The terms of this Agreement and the Lease are intended by the parties as the final expression of their agreement with respect to those terms and may
not be contradicted by evidence of any prior agreement or of any contemporaneous agreement. The parties further intend that no extrinsic evidence whatsoever may be introduced in any judicial proceeding involving this Agreement. 
 8. Successors and Assigns. Each provision of the Lease and this Agreement shall extend to and shall bind and inure to the benefit of Landlord and
Tenant, their respective heirs, legal representatives, successors and assigns. 
 9. Time of the Essence. Time is of the essence of
this Agreement and the Lease and each provision hereof. 
 10. Multiple Counterparts. This Agreement may be executed in counterparts,
all of which, when taken together, shall constitute a fully executed instrument. 
 11. Authority. Landlord and Tenant each represent
and warrant that it has full authority to execute and deliver this Agreement. 
 12. Ratification. Except as amended and modified
hereby, the Lease shall be and shall remain unchanged and in full force and effect in accordance with its terms, and, as the Lease is amended and modified hereby, the Lease is hereby ratified, adopted and confirmed.

 13. Limitation on Landlord’s Liability. It is expressly understood and agreed by Tenant that
none of Landlord’s covenants, undertakings or agreements are made or intended as personal covenants, undertakings or agreements by Landlord, and any liability of Landlord for damages or breach or nonperformance by Landlord or otherwise arising
under or in connection with this Agreement or the Lease or the relationship of Landlord and Tenant hereunder, shall be collectible only out of Landlord’s interest in the Property (or if Landlord is the beneficiary of a land trust,
Landlord’s right, title and interest in such land trust), in each case as the same may then be encumbered, and no personal liability is assumed by, nor at any time may be asserted against, Landlord, its members or its other owners, direct or
remote, all such liability, if any, being expressly waived and released by Tenant. The limitations of liability of Landlord contained herein shall apply equally to and inure to the benefit of the Landlord Protected Parties. Tenant further expressly
understands and agrees that if any instrument involving the Building is executed by Landlord’s agent (“Landlord’s Agent”) on behalf of Landlord, then Landlord’s Agent executes such instrument, not in its own right but
solely as Landlord’s Agent and that nothing in this Lease shall be construed as creating any liability whatsoever against such Landlord’s Agent, its owners, direct and remote, and their respective directors, officers or employees and in
particular, without limiting the generality of the foregoing, there shall be no liability of Landlord’s Agent to pay any indebtedness or sum accruing thereunder, or to perform any covenant or agreement whether expressed or implied therein
contained, it being agreed that Landlord shall have sole responsibility therefor. 
 14. No Offer. Submission of this Agreement by
Landlord to Tenant is not an offer to enter into this Agreement but rather is a solicitation for such an offer from Tenant. Landlord shall not be bound by this Agreement until Landlord has executed and delivered the same to Tenant.
