S. Bankruptcy Code or any state bankruptcy code (collectively, “Bankruptcy Code”), or (3) an involuntary petition has been filed against Tenant under the Bankruptcy Code, or (4) the long term rating of the issuing Bank has been downgraded to BBB or lower (by Standard & Poor’s) or Baa2 or lower (by Moody’s) and Tenant has failed to deliver a new Letter of Credit from a bank with a long term rating of A or higher (by Standard & Poor’s) or A2 or higher (by Moody’s) and otherwise meeting the requirements set forth in this Section within ten (10) Business Days following notice from Landlord.

If Landlord desires to assign the Letter of Credit, Tenant shall execute and deliver to the issuing Bank and documents required to effectuate such transfer and pay any transfer and processing fees.

The use, application or retention of the Letter of Credit, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable Legal Requirements, it being intended that Landlord shall not first be required to proceed against the Letter of Credit, and it shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the Letter of Credit. No condition or term of this Lease shall be deemed to render the Letter of Credit conditional to justify the issuing Bank in failing to honor a drawing upon such Letter of Credit in a timely manner. Tenant agrees and acknowledges that (a) the Letter of Credit constitutes a separate and independent contract between Landlord and the issuing Bank, (b) Tenant is not a third party beneficiary of such contract, (c)

Tenant has no property interest whatsoever in the Letter of Credit or the proceeds thereof, and (d) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, neither Tenant, any trustee, nor Tenants bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the Letter of Credit and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

Subject to the remaining terms of this Section 2.6 and provided that the Security Reduction Conditions are satisfied, the balance of the Letter of Credit shall be reduced to (i) $250,000.00 effective as of the last day of the 48^th full calendar month of the Term, and (ii) $0.00 effective as of the last day of the 60^th full calendar month of the Term (each a “Reduction Date”). On each Reduction Date, Tenant shall send Landlord a notice requesting Landlord to reduce the Security Deposit.

In no event shall Landlord’s receipt of funds in connection with any tax increment financing and/or a redevelopment agreement between Landlord and the City of Chicago (Including, without limitation, any “developer’s note” for the benefit of Landlord), affecting all of any portion of the Real Property constitute a refund of Taxes to which Tenant is or could be entitled to a proportionate share.

If, however. Landlord shall furnish any such estimate for a Comparison Year subsequent to the commencement thereof, then until the last day of the month following the month in which such estimate is furnished to Tenant, Tenant shall pay to Landlord on the first day of each month an amount equal to the monthly sum payable by Tenant to Landlord under this Section 7.3 during the last month of the preceding Comparison Year. Promptly after such estimate is furnished to Tenant or together therewith, Landlord shall give notice to Tenant stating whether the installments of Tenant’s Operating Payment previously made for such Comparison Year were greater or less than the installments of Tenant’s Operating Payment to be made for such Comparison Year in accordance with such estimate, and if there shall be a deficiency, Tenant shall pay the amount thereof within thirty (30) days after demand therefor, or if there shall have been an overpayment, Landlord shall credit the amount thereof against subsequent payments of Rent due hereunder, and on the first day of the month following the month in which such estimate is furnished to Tenant, and on the first day of each month thereafter throughout the remainder of such Comparison Year, Tenant shall pay to Landlord an amount squat to one-twelfth of Tenant’s Operating Payment shown on such estimate.

(b) On or before May 1st of each Comparison Year, Landfill shall furnish to Tenant a Statement for the immediately preceding Comparison Yea. Each such Statement shall be accompanied by a computation of Operating Expenses for the Building prepared by Landlord’s Agent. If the Statement shall show that the sums paid by Tenant under Section 7.3(a) exceeded the actual amount of Tenant’s Operating Payment for such Comparison Year, Landlord shall, at its election, either refund the amount of such excess to Tenant within thirty (30) days after Tenant’s receipt of the Statement or credit the amount of such excess against subsequent payments of Rent due hereunder. If the Statement for such Comparison Year shall show that the sums so paid by Tenant were less than Tenant’s Operating Payment for such Comparison Year, Tenant shall pay the amount of such deficiency within thirty (30) days after Tenant’s receipt of the Statement.

Section 7.4 Partial Lease Years. If the Commencement Date shall occur on a date other than January 1, any Additional Rent under Sections 7.2 and 7.3 for the calendar year in which such Commencement Data shall occur shall be apportioned on the basis of the number of days in the period from the Commencement Date to the following December 31 bears to the total number of days in such Comparison Year. If the Expiration Date shall occur on a date other than December 31, any Additional Rent payable by Tenant to Landlord under Sections 7.2 and 7.3 for the Comparison Year in which such Expiration Date occurs shall be apportioned on the baste of the number of days in the period from January 1 to the Expiration Date shall bear to the total number of days in such Comparison Year. In the event of the expiration or earlier termination of this Lease, any Additional Rent under Sections 7.2 and 7.3 owed by Tenant shall be paid by Tenant, and any over payments not credited against Rent payable hereunder shall be refunded by Landlord within thirty (30) days after submission of the Statement for the last Comparison Year. In no event shall Fixed Rent ever be reduced by operation of Sections 7.2 and 7.3 and the rights and obligations of Landlord and Tenant under the provisions of Sections 7.2 and 7.3 with respect to any Additional Rent shall survive the expiration or earlier termination of this Lease.

Section 7.5 Intentionally Omitted.

Section 7.6 Non-Waiver; Disputes.

(a) Landlord’s failure to render any Statement on a timely basis with respect to any Comparison Year shall not prejudice Landlord’s right to thereafter render a Statement with respect to such Comparison Year or any subsequent Comparison Year, nor shall the rendering of a Statement prejudice Landlord’s right to thereafter render a corrected Statement for that Comparison Year.

(b) Each Statement sent to Tenant shall be conclusively binding upon Tenant unless Tenant shall within thirty (30) days after such Statement is sent, pay to Landlord the amount set forth in such Statement, without prejudice to Tenant’s right to dispute such Statement, and within one hundred twenty (120) days after such Statement is sent, send a written notice to Landlord objecting to such Statement and specifying the reasons that such Statement is claimed to be incorrect. Tenant agrees that Tenant will not employ, in connection with any dispute under this Lease, any person who is to be compensated in whole or in part, on a continency fee basis. If the parties are unable to resolve any dispute as to the correctness of such Statement within thirty (30) days following such notice of objection, either party may refer the issues to a reputable public accounting firm selected by Landlord that is independent of Tenant, and Landlord and reasonably acceptable to Tenant and the decision of such accountants shall be conclusively binding upon Landlord and Tenant. In connection therewith, Tenant and such accountants shall execute and deliver to Landlord a confidentiality agreement, in form and substance, reasonably satisfactory to Landlord, whereby such parties agree not to disclose to any third party any of the information obtained in connection with such review. Tenant’s shall pay all the fees and expenses relating to such procedure unless such accountants determine that Landlord overstated Operating Expenses by more than five percent (5%) for such Lease Year, in which case Landlord shall pay such fees and expenses. If in connection with the foregoing procedure, it is determined that Tenants Tax Payment and/or Tenants Operating Payment actually paid by Tenant for the period under review exceeded the actual amount of Tenant’s Proportionate Share of Taxes and/or Operating Expenses (as applicable) for such period, then, so long as no Event of Default then exists, Landlord shall credit against Tenant’s next accruing Rent obligations an amount equal to such excess.

1.03.

Procedure for Determining Fair Market Net Rental Value. On or prior to 30 days after the later of (y) receipt of Tenants Initial Renewal Notice, and (z) the date which is 11 months prior to the last day of the then current Term, Landlord shall advise Tenant in writing of the applicable Fixed Rent rate for the Premises (or applicable portion thereof) for the Renewal Term. Tenant, within 15 days after the date on which Landlord advises Tenant of the Fixed Rent rate for the Renewal Term, shall either (i) if Tenant accepts Landlord’s determination, provide Landlord with written notice of acceptance (“Acceptance Notice”), or(ii) if Tenant disagrees with Landlord’s determination, provide Landlord with written notice of rejection (the “Rejection Notice”). If Tenant fails to provide Landlord with either an Acceptance Notice or Rejection Notice within such 30-day period, Landlord shall provide an additional written notice to Tenant (“Landlord’s Additional Notice”) advising Tenant that It has not provided Landlord with either an Acceptance Notice or a Rejection Notice and that Tenant wit be deemed to have delivered an Acceptance Notice if Tenant does not deliver to Landlord either an Acceptance Notice or a Rejection Notice within 5 Business Days after receipt of Landlord’s Additional Notice. If Tenant falls to provide Landlord with either an Acceptance Notice or a Rejection Notice within 5 Business Days after receipt of Landlord’s Additional Notice, Tenant shall be deemed to have delivered an Acceptance Notice. If Tenant provides, or Is deemed to have provided, Landlord with an Acceptance Notice within such 30-day period, or 5 Business Day period (as applicable), Landlord and Tenant shall enter into the Renewal Amendment (as defined below) upon the terms and conditions set forth herein. If Tenant provides Landlord with a Rejection Notice, Landlord and Tenant shall work together In good faith for a period of 15 days to agree upon the Fair Market Net Rental Value rate for the Premises (or applicable portion thereof) for the Renewal Term. Upon agreement, Landlord and Tenant shall enter Into the Renewal Amendment in accordance with the terms and conditions hereof.

If Landlord and Tenant fail to agree upon the Fair Market Net Rental Value rate within such 30-day period, Tenant may then retract Tenant’s applicable Initial Renewal Notice by delivering written notice of such retraction to Landlord within 10 days (the “Retraction Period”) after the expiration of such 30-day period. If Tenant does not retract Tenant’s applicable Initial Renewal Notice, within the Retraction Period, Tenant shall be deemed to have irrevocably exercised the Renewal Option, and Landlord and Tenant, within 15 days after the expiration of the Retraction Period, shall each simultaneously submit to the other, in a sealed envelope, Its good faith estimate of the Fair Market Net Rental Value rate (collectively referred to as the “Estimates”). If the higher Estimate Is less than or equal to 105% of the lower Estimate, the Fair Market Net Rental Value rate shall be the average of the Estimates. If either Landlord or Tenant fails (the “Sending Party”) to timely deliver its Estimate to the other party (the “Receiving Party”), the Receiving Party shall notify the Sending Party that the Sending Party failed to deliver its Estimate and the Sending Party shall have 5 days after receipt of such notice to deliver its Estimate to the Receiving Party. If the Sending Party fails to timely delivery its Estimate within such additional 5 days, then provided the Receiving Party timely delivered its Estimate to the Sending Party, the Estimate of the Receiving Party shall be accepted as the Fair Market Net Rental Value rate.

If the Fair Market Net Rental Value rate Is not resolved by the exchange of Estimates, Landlord and Tenant, within 7 days after the exchange of Estimates, shall each select a real estate broker to determine which of the two Estimates more closely reflects the Fair Market Net Rental Value rate. Each real estate broker selected by either Landlord or Tenant shall be a broker licensed in Chicago, Illinois, with at least 10 years continuous experience in the commercial leasing market in Chicago, Illinois, and shall have a working knowledge of current rental rates and practices for commercial office properties in Chicago, Illinois. Upon selection, Landlord’s and Tenant’s real estate brokers shall work together in good faith to agree upon which of the two Estimates more closely reflects the Fair Market Net Rental Value rate for the Premises for the Renewal Term. The Estimate chosen by such real estate brokers shall be binding on both Landlord and Tenant as the Fair Market

E-2

Net Rental Value rate for the Premises during the Renewal Term. If either Landlord or Tenant fails to appoint a real estate broker within the 7-day period referred to above, the real estate broker appointed by the other party shall be the sole real estate broker for the purposes hereof and shall determine which Estimate more closely reflects the Fair Market Net Rental Value rate for the Premises. If the two real estate brokers cannot agree upon which of the two Estimates more closely reflects the Fair Market Net Rental Value rate within the 16 days after their appointment, then, within 10 days after the expiration of such 15-day period, the two real estate brokers shall select a third real estate broker meeting the aforementioned criteria. Once the third real estate broker has been selected as provided for above, then, as soon thereafter as practicable, but In any case within 14 days, the third real estate broker shall make his or her determination of which of the two Estimates more closely reflects the Fair Market Net Rents Value rate and such Estimate shall be binding on both Landlord and Tenant as the Fair Market Net Rental Value rate for the Premises during the Renewal Term. The parties shall share equally in the costs of the third real estate broker. Any fees of any real estate broker, counsel or experts engaged directly by Landlord or Tenant, however, shall be borne by the party retaining such real estate broker, counsel or expert.

If the Fair Market Net Rental Value rate has not been determined by the commencement date of the Renewal Term, Tenant shall pay Fixed Rent upon the terms and conditions in effect for the Premises during the final month of the initial Term until such time as the Fair Market Net Rental Value rate has been determined. Upon such determination, the Fixed Rent for the Premises shall be retroactively adjusted to the commencement of the Renewal Term for the Premises. If such adjustment results in an underpayment of Fixed Rent by Tenant, Tenant shall pay Landlord the amount of such underpayment within 30 days after the determination thereof. If such adjustment results in an overpayment of Fixed Rent by Tenant, Landlord shall credit such overpayment against the next installment of Fixed Rent due under the Lease and, to the extent necessary, any subsequent installments until the entire amount of such overpayment has been credited against Fixed Rent.

1.04.

Renewal Amendment. If Tenant Is entitled to and properly exercises its Renewal Option, Landlord shall prepare an amendment (the “Renewal Amendment”) to reflect changes in the Fixed Rent, Term, Expiration Date and other appropriate terms. The Renewal Amendment shall be sent to Tenant within a reasonable time after receipt of the Acceptance Notice (or after Landlord and Tenant mutually agree upon the Fair Market Net Rental Value rate as provided in Section 1.03 above) and Tenant, within a reasonable time after receipt of the Renewal Amendment, shall execute the Renewal Amendment or, only if the Renewal Amendment purports to amend terms of the Lease other than those stated in this Section 1.04 return the Renewal Amendment to Landlord with reasonable comments, in which case, the parties shall negotiate said amendment and execute the same once agreement has been reached, but, upon final determination of the Fair Market Net Rental Value rate applicable during the Renewal Term as described herein, an otherwise valid exercise of the Renewal Option shall be fully effective whether or not the Renewal Amendment Is executed.

2.03.

THIRD AMENDMENT TO AGREEMENT OF LEASE

THIS THIRD AMENDMENT TO AGREEMENT OF LEASE (this “Amendment”) is made and entered into as of December 26, 2018 (the “Amendment Effective Date”), by and between CHICAGO KINGSBURY, LLC, a Delaware limited liability company (“Landlord”) and TEMPUS LABS, INC., a Delaware corporation (“Tenant”).

RECITALS

Landlord (as successor in interest to EQC 600 West Chicago, LLC, a Delaware limited liability company) and Tenant are parties to that certain lease dated January 18, 2018, which lease has been previously amended by First Amendment to Agreement of Lease dated as of January 30, 2018 (the “First Amendment”) and by Second Amendment to Agreement of Lease dated as of July 30, 2018 (the “Second Amendment”) (collectively, the “Lease”). Pursuant to the Lease, Landlord has leased to Tenant space currently containing approximately 79,611 Rentable Square Feet (the “Existing Premises”) on the fifth floor of the building located at 600 West Chicago Avenue, Chicago, Illinois (the “Building”).

Tenant has requested that additional space containing approximately 3,780 Rentable Square Feet on the fifth floor of the Building shown on Exhibit E-1 attached hereto as the “Fifth Expansion Space” (the “Fifth Expansion Space”) be added to the Premises currently demised under the Lease and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

C.	Landlord has determined that the Third Expansion Space (as such term is defined in Section 6 of Exhibit E to the Lease) will be available for delivery to Tenant earlier than as set forth in the Lease and the parties will to appropriately amend the Lease on the following terms and conditions.

NOW, THEREFORE, in consideration of the above recitals which by this reference are incorporated herein, the mutual covenants and conditions contained herein and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows:

1.	Fifth Expansion Space and Effective Date.

1.01

Effective on the later of (i) March 1, 2019 and (ii) the day on which possession of the Fifth Expansion Space (defined below) is delivered to Tenant (such later date is referred to as the “Fifth Expansion Effective Date”), the Premises, as defined in the Lease, is increased by the addition of the Fifth Expansion Space, and from and after the Fifth Expansion Effective Date, the Premises currently demised under the Lease and the Fifth Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease. The Term for the Fifth Expansion Space shall commence on the Fifth Expansion Effective Date and end on the Expiration Date. The Fifth Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises currently demised under the Lease unless such concessions are expressly provided for herein with respect to the Fifth Expansion Space.

1.02

Tenant shall commence payment of Rent with respect to the Fifth Expansion Space on the date (the “Fifth Expansion Rent Commencement Date”) which is the earlier of (i) 90 days after the Fifth Expansion Effective Date (the “Fifth Expansion Build Out Period”) and (ii) the date on which Tenant commences its business operations in the Fifth Expansion Space. If Tenant commences its business operations in the Fifth Expansion Space prior to the last day of the Fifth Expansion Build Out Period, the period of time beginning on the date on which Tenant so commences its business operations in the Fifth Expansion Space and ending on the last day


		1

of the Fifth Expansion Build Out Period is referred to as the “Fifth Expansion Beneficial Occupancy Period.” The initial annual Fixed Rent rate per rentable square foot of the Fifth Expansion Space shall be the same as the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease on the Fifth Expansion Rent Commencement Date. The Fixed Rent rate for the Fifth Expansion Space shall increase at such times and in such amounts as the Fixed Rent rate for the initial Premises increases, it being the intent of Landlord and Tenant that the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease and the Fixed Rent rate per rentable square foot of the Fifth Expansion Space shall be the same. Commencing on the Fifth Expansion Rent Commencement Date, Tenant’s Proportionate Share shall be increased to reflect the inclusion of the Fifth Expansion Space in the Premises. The Fifth Expansion Space shall be delivered to Tenant in its “as is” condition without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements. Any construction, alterations or improvements to the Fifth Expansion Space shall be performed by Tenant at its sole cost and expense and shall be governed in all respects by the terms of the Lease.

1.03

Tenant shall be entitled to receive an improvement allowance (the “Fifth Expansion Space Improvement Allowance”) in an amount equal to $65.00 per rentable square foot of the Fifth Expansion Space. Such Fifth Expansion Space Improvement Allowance shall be applied toward the cost of the improvements to be performed by Tenant in the Fifth Expansion Space (the “Fifth Expansion Space Improvements”). The Fifth Expansion Space Improvements shall include the construction of a demising wall to demise the Fifth Expansion Space from the adjacent office space and Common Area and separation of utilities between the Fifth Expansion space and the adjacent office space and Common Area. The Fifth Expansion Space Improvement Allowance shall be disbursed in the same manner as described in, and subject to the same terms and conditions of, Sections 7(d), (e), (f) and (g) of the Work Letter attached to the Lease as Exhibit D, except that, for purposes of this Section 1.03, (i) all references to the following terms in Sections 7(d), (e), (f) and (g) of the Work Letter shall instead have the following meanings: (A) “Tenant’s Work” shall instead refer to the “Fifth Expansion Space Improvements,” and (B) “Construction Allowance,” “Separation Work Reimbursement,” “Application Amount” and “Total Allowance” shall instead refer to the “Fifth Expansion Space Improvement Allowance,” and (ii) Tenant may use any portion of the Fifth Expansion Space Improvement Allowance in excess of the costs for the Fifth Expansion Space Improvements on the First Expansion Space Improvements, Third Expansion Space Improvements and the Fourth Expansion Space Improvements in accordance with the provisions of the Lease for disbursements of the First Expansion Space Improvement Allowance, Third Expansion Space Improvement Allowance and the Fourth Expansion Space Improvement Allowance, respectively.

1.04

Tenant shall be entitled to receive an abatement of the Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment initially payable with respect to the Fifth Expansion Space (“Fifth Expansion Space Rental Abatement”) for 12 months. Such Fifth Expansion Space Rental Abatement shall be applied toward the first rent due with respect to the Fifth Expansion Space. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Fifth Expansion Space Rental Abatement against the rent due in connection with the Fifth Expansion Space (A) unless and until Tenant shall have occupied and be operating its business in substantially all of the Fifth Expansion Space, and (B) if an Event of Default has occurred under the Lease.

1.05

Landlord shall endeavor to deliver possession of the Fifth Expansion Space to Tenant on the Fifth Expansion Effective Date. If Tenant takes possession of or enters the Fifth Expansion Space before the Fifth Expansion Rent Commencement Date, Tenant shall pay for all services requested by Tenant (e.g., freight elevator usage and utilities) and Tenant shall be subject to the terms and conditions of the Lease; provided, however, (i) except for the cost of such services requested by Tenant, Tenant shall not be required to pay Rent for any entry


		2

or possession before the Fifth Expansion Rent Commencement Date during which Tenant, with Landlord’s approval, has entered, or is in possession of, the Fifth Expansion Space for the sole purpose of performing improvements or installing furniture, equipment or other personal property, and (ii) during the Fifth Expansion Beneficial Occupancy Period, Tenant shall not be required to pay Rent but shall pay the cost of utilities and janitorial services for the Fifth Expansion Space and for any services specifically requested by Tenant. If Landlord fails to deliver possession of the Fifth Expansion Space to Tenant on the Fifth Expansion Effective Date because of any act or occurrence beyond the reasonable control of Landlord, including, without limitation, the holding over of any tenants or occupants beyond the expiration of their lease terms, then Landlord shall not be subject to any liability for failure to deliver possession, and such failure to deliver possession shall not affect either the validity of the Lease or the obligations of either Landlord or Tenant thereunder or be construed to extend the expiration of the Term either as to the Fifth Expansion Space or the balance of the Premises; provided, however, that under such circumstances, Landlord shall make reasonable efforts to obtain possession of the Fifth Expansion Space.

1.06

Upon determination of the Fifth Expansion Effective Date and the Fifth Expansion Rent Commencement Date, Landlord and Tenant shall promptly execute and deliver an amendment to the Lease reflecting the lease of the Fifth Expansion Space by Landlord to Tenant on the terms provided above.

2.	First Expansion Space. Section 6.01(a) of Exhibit E to the Lease, as modified by Section 1.01(b) of the First Amendment, is hereby modified by replacing the date “June 1, 2019” in clause (i) therein with the date “March 1, 2019”.

The rentable square footage of the Third Expansion Space set forth in this Section 6.03(a) shall be stipulated as the rentable square footage of the Third Expansion Space. The Third Expansion Space shall be leased by Tenant subject to all the terms and conditions of the Lease except as expressly modified in this Section 6.03 and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises initially demised by the Lease. Landlord and Tenant acknowledge that the Third Expansion Space is a portion of the Available ROFO Space as defined in Section 2 of Exhibit E and shall be added to the Premises pursuant to this Section 6.03 (including, without limitation, the non-prorated Third Expansion Space Rental Abatement [defined in Section 6.03(d) below] and the non-prorated Third Expansion Space Improvement Allowance [defined in Section 6.03(c) below]) and not as Offer Space under Section 2 of Exhibit E. Following the Third Expansion Effective Date, the Available ROFO Space shall no longer include the Third Expansion Space. Landlord, at its expense, shall construct a corridor (the “New Corridor”) in certain space currently leased to Wrigley under the Wrigley Lease after Landlord regains legal possession of the portion of the space currently leased to Wrigley containing the New Corridor, which construction shall occur simultaneously with Tenant’s performance of the Third Expansion Space Improvements. In consideration of delivery of the Third Expansion Space prior to the date on which Landlord originally anticipated delivery, Tenant shall pay to Landlord, as Additional Rent under the Lease, and in addition to all other Rent due under the Lease for the same period, the sum of $203,912.50, payable in equal monthly installments of $67,970.83 each on March 1, 2019, April 1, 2019 and May 1, 2019.”

THIS FOURTH AMENDMENT TO AGREEMENT OF LEASE (the “Amendment”) is made and entered into as of April 23, 2019 (the “Amendment Effective Date”), by and between CHICAGO KINGSBURY, LLC, a Delaware limited liability company (“Landlord”) and TEMPUS LABS, INC., a Delaware corporation (“Tenant”).

RECITALS

Tenant has requested that additional space containing approximately 8,020 Rentable Square Feet on the fifth floor of the Building shown on Exhibit A attached hereto as the “Sixth Expansion Space” (the “Sixth Expansion Space”) be added to the Premises currently demised under the Lease and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

In addition, Tenant has requested that additional space containing approximately 27,622 Rentable Square Feet on the fifth floor of the Building shown on Exhibit B attached hereto (the “Seventh Expansion Space”) be added to the Premises currently demised under the Lease and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions. The Seventh Expansion Space consists of 3 spaces as shown on Exhibit B: “P1” consisting of approximately 11,089 Rentable Square Feet, “P2” consisting of approximately 8,261 Rentable Square Feet and “P3” consisting of approximately 8,272 Rentable Square Feet.

This Amendment constitutes Tenant’s notice that Tenant has elected that the maximum amount of rental abatement permitted under the Lease and this Amendment attributable to the First Expansion Space, Third Expansion Space, Fifth Expansion Space, Sixth Expansion Space and Seventh Expansion Space be converted to Application Amount, and the parties wish to set forth the revised rental abatement periods and the Application Amount resulting therefrom.

1.	Sixth Expansion Space and Effective Date.

1.01

Effective as of March 1, 2019 (the “Sixth Expansion Effective Date”), the Premises, as defined in the Lease, is increased by the addition of the Sixth Expansion Space, and from and after the Sixth Expansion Effective Date, the Premises currently demised under the Lease and the Sixth Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease. The Term for the Sixth Expansion Space shall commence on the Sixth Expansion


		1

Effective Date and end on the Expiration Date. The Sixth Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises currently demised under the Lease unless such concessions are expressly provided for herein with respect to the Sixth Expansion Space.

1.02

Tenant shall commence payment of Rent with respect to the Sixth Expansion Space on December 1, 2019 (the “Sixth Expansion Rent Commencement Date”) which is the date 275 days after the Sixth Expansion Effective Date (the “Sixth Expansion Build Out Period”). If Tenant commences its business operations in the Sixth Expansion Space prior to the last day of the Sixth Expansion Build Out Period, the period of time beginning on the date on which Tenant so commences its business operations in the Sixth Expansion Space and ending on the last day of the Sixth Expansion Build Out Period is referred to as the “Sixth Expansion Beneficial Occupancy Period.” The initial annual Fixed Rent rate per rentable square foot of the Sixth Expansion Space shall be the same as the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease on the Sixth Expansion Rent Commencement Date. The Fixed Rent rate for the Sixth Expansion Space shall increase at such times and in such amounts as the Fixed Rent rate for the initial Premises increases, it being the intent of Landlord and Tenant that the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease and the Fixed Rent rate per rentable square foot of the Sixth Expansion Space shall be the same. Commencing on the Sixth Expansion Rent Commencement Date, Tenant’s Proportionate Share shall be increased to reflect the inclusion of the Sixth Expansion Space in the Premises. The Sixth Expansion Space shall be delivered to Tenant in its “as is” condition without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements. Any construction, alterations or improvements to the Sixth Expansion Space shall be performed by Tenant at its sole cost and expense and shall be governed in all respects by the terms of the Lease.

1.03

Tenant shall be entitled to receive an improvement allowance (the “Sixth Expansion Space Improvement Allowance”) in an amount equal to $65.00 per rentable square foot of the Sixth Expansion Space. Such Sixth Expansion Space Improvement Allowance shall be applied toward the cost of the improvements to be performed by Tenant in the Sixth Expansion Space (the “Sixth Expansion Space Improvements”) and/or the cost of the First Expansion Space Improvements, Third Expansion Space Improvements, Fifth Expansion Space Improvements and the Seventh Expansion Space Improvements in accordance with the provisions of the Lease for disbursements of the First Expansion Space Improvement Allowance, Third Expansion Space Improvement Allowance, Fifth Expansion Space Improvement Allowance and Seventh Expansion Space Improvement Allowance, respectively. The Sixth Expansion Space Improvement Allowance shall be disbursed in the same manner as described in, and subject to the same terms and conditions of, Sections 7(d), (e), (f) and (g) of the Work Letter attached to the Lease as Exhibit D, except that, for purposes of this Section 1.03, all references in Sections 7(d), (e), (f) and (g) of the Work Letter to (A) “Tenant’s Work” shall instead refer to the “Sixth Expansion Space Improvements”, (B) “Construction Allowance” shall instead refer to the “Sixth Expansion Space Improvement Allowance”, (C) “Separation Work Reimbursement,” shall be deleted, (D) “Application Amount” shall instead refer to that portion of the Application Amount applicable to the Sixth Expansion Space as set forth on Exhibit C-4 attached hereto, and (E) “Total Allowance” shall instead refer to the sum of (i) the Sixth Expansion Space Improvement Allowance plus (ii) that portion of the Application Amount applicable to the Sixth Expansion Space, all as set forth on Exhibit C-4 attached hereto. For the avoidance of doubt, there is no Separation Work and no Separation Work Reimbursement in connection with the Sixth Expansion Space. Notwithstanding anything contained in this Section 1.03, and regardless of the availability of the Sixth Expansion Space Improvement Allowance for the Sixth Expansion Space Improvements


		2

(because Tenant has chosen to apply the Sixth Expansion Space Improvement Allowance to other portions of the Premises), Tenant covenants and agrees that Tenant shall construct the Sixth Expansion Space Improvements such that the entirety of the Sixth Expansion Space is substantially similar in quality of finishes, materials and workmanship as the improvements in the balance of the Premises as of the date of this Amendment.

1.04

Tenant shall be entitled to receive an abatement of the Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment initially payable with respect to the Sixth Expansion Space (collectively, the “Sixth Expansion Space Rental Abatement”) as more particularly described on Exhibit C-3 attached hereto and made a part hereof. Such Sixth Expansion Space Rental Abatement shall be applied toward the first rent due with respect to the Sixth Expansion Space. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Sixth Expansion Space Rental Abatement against the rent due in connection with the Sixth Expansion Space (A) unless and until Tenant shall have occupied and be operating its business in substantially all of the Sixth Expansion Space, and (B) if an Event of Default has occurred under the Lease.

1.05

If Tenant takes possession of or enters the Sixth Expansion Space before the Sixth Expansion Rent Commencement Date, Tenant shall pay for all services requested by Tenant (e.g., freight elevator usage and utilities) and Tenant shall be subject to the terms and conditions of the Lease; provided, however, (i) except for the cost of such services requested by Tenant, Tenant shall not be required to pay Rent for any entry or possession before the Sixth Expansion Rent Commencement Date during which Tenant, with Landlord’s approval, has entered, or is in possession of, the Sixth Expansion Space for the sole purpose of performing improvements or installing furniture, equipment or other personal property, and (ii) during the Sixth Expansion Beneficial Occupancy Period, Tenant shall not be required to pay Rent but shall pay the cost of utilities and janitorial services for the Sixth Expansion Space and for any services specifically requested by Tenant.

1.06

Tenant shall be entitled to receive $120,300.00 as Application Amount with respect to the Sixth Expansion Space, which amount shall be disbursed together with, and in accordance with the terms and conditions of disbursement of, the Sixth Expansion Space Improvement Allowance.

2.	Seventh Expansion Space and Effective Date.

2.01

Effective as of May 1, 2019 (the “Seventh Expansion Effective Date”), the Premises, as defined in the Lease, is increased by the addition of the Seventh Expansion Space, and from and after the Seventh Expansion Effective Date, the Premises currently demised under the Lease and the Seventh Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease. The Term for the Seventh Expansion Space shall commence on the Seventh Expansion Effective Date and end on the Expiration Date. The Seventh Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises currently demised under the Lease unless such concessions are expressly provided for herein with respect to the Seventh Expansion Space.

2.02

Tenant shall commence payment of Rent with respect to the Seventh Expansion Space on the dates set forth as the respective Rent Commencement Dates of the Seventh Expansion Space (collectively, the “Seventh Expansion Rent Commencement Date”) as more particularly set forth on Exhibit C-1 attached hereto and made a part hereof. If Tenant commences its business operations in the P1, P2 or P3 portions of the Seventh Expansion Space prior to each respective Seventh Expansion Rent Commencement Date, the period of time beginning on the date on which Tenant so commences its business operations in the


		3

respective portion of the Seventh Expansion Space and ending on the last day of the P1 Build Out Period, P2 Build Out Period or P3 Build Out Period, as the case may be, is individually and collectively and referred to as the “Seventh Expansion Beneficial Occupancy Period.” The initial annual Fixed Rent rate per rentable square foot of the Seventh Expansion Space shall be the same as the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease on the respective Seventh Expansion Rent Commencement Date. The Fixed Rent rate for the Seventh Expansion Space shall increase at such times and in such amounts as the Fixed Rent rate for the initial Premises increases, it being the intent of Landlord and Tenant that the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease and the Fixed Rent rate per rentable square foot of the Seventh Expansion Space shall be the same. Commencing on each respective Seventh Expansion Rent Commencement Date, Tenant’s Proportionate Share shall be increased to reflect the inclusion of each respective portion of the Seventh Expansion Space in the Premises. The Seventh Expansion Space shall be delivered to Tenant in its “as is” condition without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements. Any construction, alterations or improvements to the Seventh Expansion Space shall be performed by Tenant at its sole cost and expense and shall be governed in all respects by the terms of the Lease.

2.03

Tenant shall be entitled to receive an improvement allowance for each portion of the Seventh Expansion Space in the amounts set forth on Exhibit C-4 attached hereto and made a part hereof. Such allowances shall respectively be known as the “P1 Improvement Allowance”, the “P2 Improvement Allowance”, and the “P3 Improvement Allowance.” The P1 Improvement Allowance, P2 Improvement Allowance and P3 Improvement Allowance are collectively referred to as “Seventh Expansion Space Improvement Allowance.” Such Seventh Expansion Space Improvement Allowance shall be applied toward the cost of the improvements to be performed by Tenant in the Seventh Expansion Space (the “Seventh Expansion Space Improvements”) and/or the First Expansion Space Improvements. Third Expansion Space Improvements. Fifth Expansion Space Improvements and Sixth Expansion Space Improvements in accordance with the provisions of the Lease for disbursements of the First Expansion Space Improvement Allowance, Third Expansion Space Improvement Allowance, Fifth Expansion Space Improvement Allowance and Sixth Expansion Space Improvement Allowance, respectively. The Seventh Expansion Space Improvement Allowance shall be disbursed in the same manner as described in, and subject to the same terms and conditions of, Sections 7(d), (e), (1) and (g) of the Work Letter attached to the Lease as Exhibit D, except that, for purposes of this Section 2,03, all references in Sections 7(d), (e), (f) and (g) of the Work Letter to (A) “Tenant’s Work” shall instead refer to the “Seventh Expansion Space Improvements”, (B) “Construction Allowance” shall instead refer to the “Seventh Expansion Space Improvement Allowance”, (C) “Separation Work Reimbursement” shall be deleted, (D) “Application Amount” shall instead refer to that portion of the Application Amount applicable to the Seventh Expansion Space as set forth on Exhibit C-4 attached hereto, and (E) “Total Allowance” shall instead refer to the sum of (i) the Seventh Expansion Space Improvement Allowance plus (ii) that portion of the Application Amount applicable to the Seventh Expansion Space, all as set forth on Exhibit C-4 attached hereto. For the avoidance of doubt, there is no Separation Work and no Separation Work Reimbursement in connection with the Seventh Expansion Space. The Seventh Expansion Space Improvement Allowance shall be available to Tenant as of the Seventh Expansion Effective Date. Notwithstanding anything contained in this Section 2.03, and regardless of the availability of the Seventh Expansion Space Improvement Allowance for the Seventh Expansion Space Improvements (because Tenant has chosen to apply the Seventh Expansion Space Improvement Allowance to other portions of the Premises), Tenant covenants and agrees that Tenant shall construct the Seventh Expansion Space Improvements such that the entirety of the Seventh Expansion Space is substantially similar in quality of finishes, materials and workmanship as the improvements in the balance of the Premises as of the date of this Amendment.

P2 Rental Abatement and P3 Rental Abatement are collectively referred to herein as the “Seventh Expansion Space Rental Abatement.” Such Seventh Expansion Space Rental Abatement shall be applied toward the first rent due with respect to each respective portion of the Seventh Expansion Space. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the P1 Rental Abatement, the P2 Rental Abatement or the P3 Rental Abatement, as the case may be, against the rent due in connection with the P1, P2 or P3 portions of the Seventh Expansion Space, respectively, (A) unless and until Tenant shall have occupied and be operating its business in substantially all of the P1, P2 and P3 portions of the Seventh Expansion Space, respectively, and (B) if an Event of Default has occurred under the Lease.

2.05

If Tenant takes possession of or enters the P1, P2 or P3 portions of the Seventh Expansion Space before the respective Seventh Expansion Rent Commencement Date, Tenant shall pay for all services requested by Tenant (e.g., freight elevator usage and utilities) and Tenant shall be subject to the terms and conditions of the Lease; provided, however, (i) except for the cost of such services requested by Tenant, Tenant shall not be required to pay Rent for any entry or possession before the respective Seventh Expansion Rent Commencement Date during which Tenant has entered, or is in possession of, the P1, P2 or P3 portions of the Seventh Expansion Space for the sole purpose of performing improvements in accordance with the terms of the Lease or installing furniture, equipment or other personal property, and (ii) during each respective Seventh Expansion Beneficial Occupancy Period, Tenant shall not be required to pay Rent but shall pay the cost of utilities and janitorial services for the respective portion of the Seventh Expansion Space and for any services specifically requested by Tenant. If Landlord fails to deliver possession of any portion of the Seventh Expansion Space to Tenant on the Seventh Expansion Effective Date because of any act or occurrence beyond the reasonable control of Landlord, including, without limitation, the holding over of any tenants or occupants beyond the expiration of their lease terms, then Landlord shall not be subject to any liability for failure to deliver possession, and such failure to deliver possession shall not affect either the validity of the Lease or the obligations of either Landlord or Tenant thereunder or be construed to extend the expiration of the Term either as to the Seventh Expansion Space or the balance of the Premises; provided, however, that under such circumstances, Landlord shall make reasonable efforts to obtain possession of the respective portion of the Seventh Expansion Space.

2.06

Tenant shall be entitled to receive the respective amounts set forth on Exhibit C-4 attached hereto and made a part hereof as Application Amount with respect to the Seventh Expansion Space, which amounts shall be disbursed together with, and in accordance with the terms and conditions of disbursement of, the P1 Improvement Allowance, the P2 Improvement Allowance and the P3 Improvement Allowance, respectively:

		5

Rental Abatement and Application Amount. Based on Tenant’s election to convert the maximum amount of the First Expansion Space Rental Abatement, the Third Expansion Space Rental Abatement and the Fifth Expansion Space Rental Abatement to Application Amount, notwithstanding anything to the contrary contained in the Lease, including, without limitation, Sections 6.01(d) and 6.03(d) of the Exhibit E to the Original Lease and Section 1.04 of the Third Amendment, Tenant shall be entitled to receive the rental abatements and Application Amounts with respect to the First Expansion Space, the Third Expansion Space and the Fifth Expansion Space all as set forth on Exhibits C-3 and C-4 attached hereto and made a part hereof.

For the avoidance of doubt, Tenant’s valid exercise of the Termination Option terminates the Lease with respect to the entire Premises effective as of the Early Termination Date set forth in Section 3.01 of Exhibit E to the Lease.

FIFTH AMENDMENT TO AGREEMENT OF LEASE

THIS FIFTH AMENDMENT TO AGREEMENT OF LEASE (the “Amendment”) is made and entered into as of May 8 , 2020 (the “Amendment Effective Date”), by and between CHICAGO KINGSBURY, LLC, a Delaware limited liability company (“Landlord”) and TEMPUS LABS, INC., a Delaware corporation (“Tenant”).

RECITALS

Landlord (as successor in interest to EQC 600 West Chicago, LLC, a Delaware limited liability company) and Tenant are parties to that certain lease dated January 18, 2018 (the “Original Lease”), which lease has been previously amended by First Amendment to Agreement of Lease dated as of January 30, 2018 (the “First Amendment”), by Second Amendment to Agreement of Lease dated as of July 30, 2018 (the “Second Amendment”), by Third Amendment to Agreement of Lease dated as of December 26, 2018 (the “Third Amendment”) and by Fourth Amendment to Agreement of Lease dated as of April 23, 2019 (the “Fourth Amendment”) (collectively, the “Lease”). Pursuant to the Lease, Landlord has leased to Tenant space currently containing approximately 154,606 Rentable Square Feet on the 5th floor of the Building located at 600 West Chicago Avenue, Chicago, Illinois (the “Building”) which consists of the space demised in Section 2.1 of the Original Lease, the First Expansion Space and the Third Expansion Space demised in Section 6 of Exhibit G to the Original Lease (as amended), the Fourth Expansion Space demised in the Second Amendment, the Fifth Expansion Space demised in the Third Amendment and the Sixth Expansion Space and Seventh Expansion Space demised in the Fourth Amendment (the “Premises”).

Tenant has requested that additional space containing approximately 13,129 Rentable Square Feet on the seventh floor of the Building shown on Exhibit A attached hereto as the “Eighth Expansion Space” (the “Eighth Expansion Space”) be added to the Premises currently demised under the Lease and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

1.	Eighth Expansion Space and Effective Date.

1.01

Effective on the Amendment Effective Date (the “Eighth Expansion Effective Date”), the Premises, as defined in the Lease, is increased by the addition of the Eighth Expansion Space, and from and after the Eighth Expansion Effective Date, the Premises currently demised under the Lease and the Eighth Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease. The Term for the Eighth Expansion Space shall commence on the Eighth Expansion Effective Date and end on the Expiration Date. The Eighth Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises currently demised under the Lease unless such concessions are expressly provided for herein with respect to the Eighth Expansion Space.

1.02

Tenant shall commence payment of Rent with respect to the Eighth Expansion Space on December 1, 2020 (the “Eighth Expansion Rent Commencement Date”). The period of time commencing on the Eighth Expansion Effective Date and continuing until the date immediately preceding the Eighth Expansion Rent Commencement Date is referred to herein as the “Eighth Expansion Build Out Period”. If Tenant commences its business operations in the

Eighth Expansion Space prior to the last day of the Eighth Expansion Build Out Period, the period of time beginning on the date on which Tenant so commences its business operations in the Eighth Expansion Space and ending on the last day of the Eighth Expansion Build Out Period is referred to as the “Eighth Expansion Beneficial Occupancy Period.” The initial annual Fixed Rent rate per rentable square foot of the Eighth Expansion Space shall be the same as the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease on the Eighth Expansion Rent Commencement Date. The Fixed Rent rate for the Eighth Expansion Space shall increase at such times and in such amounts as the Fixed Rent rate for the initial Premises increases, it being the intent of Landlord and Tenant that the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease and the Fixed Rent rate per rentable square foot of the Eighth Expansion Space shall be the same. Commencing on the Eighth Expansion Rent Commencement Date, Tenant’s Proportionate Share shall be increased to reflect the inclusion of the Eighth Expansion Space in the Premises. The Eighth Expansion Space shall be delivered to Tenant in its “as is” condition without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements. Any construction, alterations or improvements to the Eighth Expansion Space shall be performed by Tenant at its sole cost and expense and shall be governed in all respects by the terms of the Lease.

1.03

Tenant shall be entitled to receive an improvement allowance (the “Eighth Expansion Space Improvement Allowance”) in an amount equal to $50.00 per rentable square foot of the Eighth Expansion Space. Such Eighth Expansion Space Improvement Allowance shall be applied toward the cost of the improvements to be performed by Tenant in the Eighth Expansion Space (the “Eighth Expansion Space Improvements”). The Eighth Expansion Space Improvements shall include the construction of a demising wall to demise the Eighth Expansion Space from the adjacent office space and Common Area and separation of utilities between the Eighth Expansion space and the adjacent office space and Common Area. The Eighth Expansion Space Improvement Allowance shall be disbursed in the same manner as described in, and subject to the same terms and conditions of, Sections 7(d), (e), (f) and (g) of the Work Letter attached to the Lease as Exhibit D, except that, for purposes of this Section 1.03, all references to the following terms in Sections 7(d), (e), (f) and (g) of the Work Letter shall instead have the following meanings: (A) “Tenant’s Work” shall instead refer to the “Eighth Expansion Space Improvements,” and (B) “Construction Allowance,” “Separation Work Reimbursement,” “Application Amount” and “Total Allowance” shall instead refer to the “Eighth Expansion Space Improvement Allowance”.

1.04

Landlord acknowledges and agrees that Section 7(h) of Exhibit D to the Lease shall remain in effect with respect to the Eighth Expansion Space Improvement Allowance such that, if (1) the Eighth Expansion Space Improvements have been completed and (2) all costs related thereto have been paid in full, and less than the entire Eighth Expansion Space Improvement Allowance was used (and the portion not used shall be called the “Eighth Expansion Space Unused Allowance”), then provided Tenant is not then in default under the Lease, Tenant may request that Landlord apply a portion of the Eighth Expansion Space Unused Allowance not to exceed $164,112.50, or 25% of the Eighth Expansion Space Improvement Allowance, against the then next due installments of Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment payable with respect to the Eighth Expansion Space. Notwithstanding anything herein to the contrary, Landlord shall not be obligated to allow the Eighth Expansion Space Unused Allowance to be applied against any portion of the rent for the Eighth Expansion Space during the continuance of an uncured default under the Lease and Landlord’s obligation to allow such application shall only resume when and if such default is cured.

1.05

Tenant shall be entitled to receive an abatement of 50% of the Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment initially payable with respect to the Eighth Expansion Space (“Eighth Expansion Space Rental Abatement”) for 36 months. Such Eighth Expansion Space Rental Abatement shall be applied toward the first rent due with respect to the Eighth Expansion Space. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Eighth Expansion Space Rental Abatement against the rent due in connection with the Eighth Expansion Space (A) unless and until Tenant shall have occupied and be operating its business in substantially all of the Eighth Expansion Space, and (B) if an Event of Default has occurred and is continuing under the Lease.

1.06

If Tenant takes possession of or enters the Eighth Expansion Space before the Eighth Expansion Rent Commencement Date, Tenant shall pay for all services requested by Tenant (e.g., freight elevator usage and utilities) and Tenant shall be subject to the terms and conditions of the Lease; provided, however, (i) except for the cost of such services requested by Tenant, Tenant shall not be required to pay Rent for any entry or possession before the Eighth Expansion Rent Commencement Date during which Tenant, with Landlord’s approval, has entered, or is in possession of, the Eighth Expansion Space for the sole purpose of performing improvements or installing furniture, equipment or other personal property, and (ii) during the Eighth Expansion Beneficial Occupancy Period, Tenant shall not be required to pay Rent but shall pay the cost of utilities and janitorial services for the Eighth Expansion Space and for any services specifically requested by Tenant. If Landlord fails to deliver possession of the Eighth Expansion Space to Tenant on the Eighth Expansion Effective Date because of any act or occurrence beyond the reasonable control of Landlord, including, without limitation, the holding over of any tenants or occupants beyond the expiration of their lease terms, then Landlord shall not be subject to any liability for failure to deliver possession, and such failure to deliver possession shall not affect either the validity of the Lease or the obligations of either Landlord or Tenant thereunder or be construed to extend the expiration of the Term either as to the Eighth Expansion Space or the balance of the Premises; provided, however, that under such circumstances, Landlord shall make reasonable efforts to obtain possession of the Eighth Expansion Space.

Early Termination Payment. As of the Eighth Expansion Effective Date, the Early Termination Payment is estimated to be $8,117,397.00, subject to recalculation after determination of the actual amount of Tenant’s Operating Payments and Tenant’s Tax Payments included in the rental abatements granted with respect to each portion of the Premises. The parties acknowledge and agree that, for purposes of calculating the portion of the Early Termination Payment attributable to the Eighth Expansion Space, only $40.00 per rentable square foot of the Eighth Expansion Space Improvement Allowance shall be included in such calculation. For the avoidance of doubt, Tenant’s valid exercise of the Termination Option terminates the Lease with respect to the entire Premises effective as of the Early Termination Date set forth in Section 3.01 of Exhibit E to the Lease.

Aggregate Terms. For convenience, attached are the following exhibits setting forth certain aggregate terms relating to the Premises: (i) attached as Exhibit A-1 is a depiction of the Premises (other than the Eighth Expansion Space) (and Exhibit A and Exhibit A-1 together depict the entire Premises as of the Effective Date), (i) attached as Exhibit C-1 is a table with the aggregate Premises, rent commencement dates, as well as other terms for the entire Premises, (ii) attached as Exhibit C-2 is a table with the aggregate Fixed Rent for the entire Premises, (iii) attached as Exhibit C-3 is a table with the aggregate rental abatements and rental abatement periods for the entire Premises, (iv) attached as Exhibit C-4 hereto is a table with the aggregate Improvement Allowances and Application Amounts for the Premises (other than the Eighth Expansion Space), and (v) attached as Exhibit C-5, is a table with the aggregate Tenant’s Proportionate Share for the entire Premises.

4.	Miscellaneous.

4.02

Except as herein modified or amended, the provisions, conditions and terms of the Lease shall remain unchanged and in full force and effect.

4.03

In the case of any inconsistency between the provisions of the Lease and this Amendment, the provisions of this Amendment shall govern and control.

4.04

4.05

4.06

Tenant hereby represents to Landlord that Tenant has dealt with no broker in connection with this Amendment other than CBRE, Inc. (“Tenant’s Broker”). Tenant agrees to indemnify and hold the Landlord Parties harmless from all claims of any other broker claiming to have represented Tenant in connection with this Amendment. Landlord hereby represents to Tenant that Landlord has dealt with no broker in connection with this Amendment. Landlord agrees to indemnify and hold the Tenant Parties harmless from all claims of any brokers claiming to have represented Landlord in connection with this Amendment. Landlord hereby agrees to pay all brokerage commissions or finder’s fees (if any) that may be due to the Tenant’s Broker in connection with this Amendment pursuant to its written agreement with such broker.

4.07

Each signatory of this Amendment represents hereby that he or she has the authority to execute and deliver the same on behalf of the party hereto for which such signatory is acting. Tenant agrees that Tenant may acknowledge only the existence of this Amendment by and between Landlord and Tenant, that Tenant may not disclose any of the terms and provisions contained in this Amendment to any tenant or other occupant in the Building or to any agent, employee, subtenant or assignee of such tenant or occupant, and Tenant also shall cause the Tenant Parties (including, without limitation, its brokers) to comply with the restrictions set forth in this sentence. The terms and provisions of the preceding sentence shall survive the termination of the Lease (whether by lapse of time or otherwise).

4.08

This Amendment shall be construed without regard to any presumption or other rule requiring construction against the party causing this Amendment to be drafted. This Amendment may be executed in counterparts and shall constitute an agreement binding on all parties notwithstanding that all parties are not signatories to the original or the same counterpart, provided that all parties are furnished a copy or copies thereof reflecting the signature of all parties. The parties acknowledge and agree that they intend to conduct this transaction by electronic means and that this Amendment may be executed by electronic signature, which shall be considered as an original signature for all purposes and shall have the same force and effect as an original signature. Without limitation, in addition to electronically produced signatures, “electronic signature” shall include faxed versions of an original signature or electronically scanned and transmitted versions (e.g., via pdf) of an original signature.

4.09

This Amendment contains the following exhibits, which are incorporated herein by reference: Exhibit A (Eighth Expansion Space), Exhibit A-1 (Remainder of Premises), Exhibit C-1 (Aggregate Terms- Premises and Dates), Exhibit C-2 (Aggregate Terms – Fixed Rent), Exhibit C-3 (Aggregate Terms – Rental Abatement Periods), Exhibit C-4 (Aggregate Terms – Improvement Allowance and Application Amounts), and Exhibit C-5 (Aggregate Terms – Tenant’s Proportionate Share).

SIXTH AMENDMENT TO AGREEMENT OF LEASE

THIS SIXTH AMENDMENT TO AGREEMENT OF LEASE (this “Amendment”) is made and entered into as of May 4, 2021 (the “Amendment Effective Date”), by and between CHICAGO KINGSBURY, LLC, a Delaware limited liability company (“Landlord”) and TEMPUS LABS, INC., a Delaware corporation (“Tenant”).

RECITALS

Landlord (as successor in interest to EQC 600 West Chicago, LLC, a Delaware limited liability company) and Tenant are parties to that certain lease dated January 18, 2018 (the “Original Lease”), which lease has been previously amended by First Amendment to Agreement of Lease dated as of January 30, 2018 (the “First Amendment”), by Second Amendment to Agreement of Lease dated as of July 30, 2018 (the “Second Amendment”), by Third Amendment to Agreement of Lease dated as of December 26, 2018 (the “Third Amendment”), by Fourth Amendment to Agreement of Lease dated as of April 23, 2019 (the “Fourth Amendment”) and by Fifth Amendment to Agreement of Lease dated as of May 8, 2020 (the “Fifth Amendment”) (collectively, the “Lease”). Pursuant to the Lease, Landlord has leased to Tenant space currently containing approximately 167,735 Rentable Square Feet on the 5th and 7th floors of the Building located at 600 West Chicago Avenue, Chicago, Illinois (the “Building”) which consists of the space demised in Section 2.1 of the Original Lease, the First Expansion Space and the Third Expansion Space demised in Section 6 of Exhibit G to the Original Lease (as amended), the Fourth Expansion Space demised in the Second Amendment, the Fifth Expansion Space demised in the Third Amendment, the Sixth Expansion Space and Seventh Expansion Space demised in the Fourth Amendment and the Eighth Expansion Space demised in the Fifth Amendment (the “Premises”).

Tenant has requested that additional space containing approximately 12,303 Rentable Square Feet on the 2^nd floor of the Building shown on Exhibit A attached hereto as the “Ninth Expansion Space” (the “Ninth Expansion Space”) be added to the Premises currently demised under the Lease and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

1.	Ninth Expansion Space and Effective Date.

1.01

Effective on July 1, 2021 (the “Ninth Expansion Effective Date”), the Premises, as defined in the Lease, is increased by the addition of the Ninth Expansion Space, and from and after the Ninth Expansion Effective Date, the Premises currently demised under the Lease and the Ninth Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease. The Term for the Ninth Expansion Space shall commence on the Ninth Expansion Effective Date and end on the Expiration Date. The Ninth Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises currently demised under the Lease unless such concessions are expressly provided for herein with respect to the Ninth Expansion Space.

1.02

Tenant shall commence payment of Rent with respect to the Ninth Expansion Space on the Ninth Expansion Effective Date, subject to Section 1.03 below. The initial annual Fixed Rent rate per rentable square foot of the Ninth Expansion Space shall be the same as the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease on the Ninth Expansion Effective Date. The Fixed Rent rate for the Ninth Expansion Space shall increase at


		1

such times and in such amounts as the Fixed Rent rate for the initial Premises increases, it being the intent of Landlord and Tenant that the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease and the Fixed Rent rate per rentable square foot of the Ninth Expansion Space shall be the same. Commencing on the Ninth Expansion Effective Date, Tenant’s Proportionate Share shall be increased to reflect the inclusion of the Ninth Expansion Space in the Premises and shall equal 15.0647%. The Ninth Expansion Space shall be delivered to Tenant in its “as is” condition without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements. Any construction, alterations or improvements to the Ninth Expansion Space shall be performed by Tenant at its sole cost and expense and shall be governed in all respects by the terms of the Lease.

1.03

Tenant shall be entitled to receive an abatement of 100% of the Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment initially payable with respect to the Ninth Expansion Space (“Ninth Expansion Space First Rental Abatement”) for 6 consecutive months commencing on the Ninth Expansion Effective Date. Such Ninth Expansion Space First Rental Abatement shall be applied toward the first rent due with respect to the Ninth Expansion Space. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Ninth Expansion Space First Rental Abatement against the rent due in connection with the Ninth Expansion Space if an Event of Default has occurred and is continuing under the Lease.

1.04

In addition to the Ninth Expansion Space First Rental Abatement, Tenant shall be entitled to receive an abatement of 50% of the Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment initially payable with respect to the Ninth Expansion Space (“Ninth Expansion Space Second Rental Abatement”) for 42 consecutive months commencing on March 1, 2024 (“Ninth Expansion Space Second Rental Abatement Period”). Such Ninth Expansion Space Second Rental Abatement shall be applied toward the first rent due with respect to the Ninth Expansion Space commencing on March 1, 2024. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Ninth Expansion Space Second Rental Abatement against the rent due in connection with the Ninth Expansion Space if an Event of Default has occurred and is continuing under the Lease, provided if such Event of Default is cured, then Tenant shall again be entitled to apply the Ninth Expansion Space Second Rental Abatement against the rent due in connection with the Ninth Expansion Space and the Ninth Expansion Space Second Rental Abatement Period shall be extended by the period of time that the Ninth Expansion Space Second Rental Abatement was suspended such that Tenant receives the full benefit of the Ninth Expansion Space Second Rental Abatement for the equivalent of the full Ninth Expansion Space Second Rental Abatement Period.

1.05

If Landlord fails to deliver possession of the Ninth Expansion Space to Tenant on the Ninth Expansion Effective Date because of any act or occurrence beyond the reasonable control of Landlord, including, without limitation, the holding over of any tenants or occupants beyond the expiration of their lease terms, then Landlord shall not be subject to any liability for failure to deliver possession, and such failure to deliver possession shall not affect either the validity of the Lease or the obligations of either Landlord or Tenant thereunder or be construed to extend the expiration of the Term either as to the Ninth Expansion Space or the balance of the Premises; provided, however, that under such circumstances, Landlord shall make reasonable efforts to obtain possession of the Ninth Expansion Space.

1.06

Tenant acknowledges that the Ninth Expansion Space was previously leased by Uptake Technologies, Inc. (“Uptake”), pursuant to a lease with Landlord, which lease terminated as to the Ninth Expansion Space on the day prior to the Ninth Expansion Effective Date. Uptake has agreed with Landlord to leave all furniture, fixtures and equipment, including, without limitation, teledata cabling and phone systems, except for the items listed on Exhibit B attached hereto (“Uptake’s Removal FF&E”; all such furniture, fixtures and equipment other than Uptake’s Removal FF&E is referred to as “Uptake’s FF&E”) located in the Ninth Expansion Space as of


		2

the day prior to the Ninth Expansion Effective Date and Tenant agrees to accept Uptake’s FF&E that is located in the Ninth Expansion Space on the Ninth Expansion Effective Date. Landlord makes no representation or warranty as to the condition, quantity, type or usefulness of Uptake’s FF&E and Tenant acknowledges that Landlord shall not have any obligation to inspect the Ninth Expansion Space regarding the condition, quantity, type or usefulness of Uptake’s FF&E. Tenant will cause Uptake to convey Uptake’s FF&E to Tenant by bill of sale.

Early Termination Payment. As of the Ninth Expansion Effective Date, the Early Termination Payment is estimated to be $8,786,354.00, subject to recalculation after determination of the actual amount of Tenant’s Operating Payments and Tenant’s Tax Payments included in the rental abatements granted with respect to each portion of the Premises. For the avoidance of doubt, Tenant’s valid exercise of the Termination Option terminates the Lease with respect to the entire Premises effective as of the Early Termination Date set forth in Section 3.01 of Exhibit E to the Lease.

Parking Spaces. Effective on the Ninth Expansion Effective Date, Landlord shall license to Tenant an additional 5 Reserved Parking Spaces, for a total of 8 Reserved Parking Spaces. Such additional 5 Reserved Parking Spaces shall be located on Level P-4 of the 900 Parking Garage and shall in all other respects be subject to the terms of Section 10.7, as amended, of the Lease.

5.	Miscellaneous.

5.01

5.02

Except as herein modified or amended, the provisions, conditions and terms of the Lease shall remain unchanged and in full force and effect.

5.03

In the case of any inconsistency between the provisions of the Lease and this Amendment, the provisions of this Amendment shall govern and control.

5.04

5.06

Tenant hereby represents to Landlord that Tenant has dealt with no broker in connection with this Amendment other than CBRE, Inc. (“Tenant’s Broker”).

5.07

Each signatory of this Amendment represents hereby that he or she has the authority to execute and deliver the same on behalf of the party hereto for which such signatory is acting. Tenant agrees that Tenant may acknowledge only the existence of this Amendment by and between Landlord and Tenant, that Tenant may not disclose any of the terms and provisions contained in this Amendment to any tenant or other occupant in the Building or to any agent, employee, subtenant or assignee of such tenant or occupant, and Tenant also shall cause the Tenant Parties (including, without limitation, its brokers) to comply with the restrictions set forth in this sentence. The terms and provisions of the preceding sentence shall survive the termination of the Lease (whether by lapse of time or otherwise).

5.08

This Amendment shall be construed without regard to any presumption or other rule requiring construction against the party causing this Amendment to be drafted. This Amendment may be executed in counterparts and shall constitute an agreement binding on all parties notwithstanding that all parties are not signatories to the original or the same counterpart, provided that all parties are furnished a copy or copies thereof reflecting the signature of all parties. The parties acknowledge and agree that they intend to conduct this transaction by electronic means and that this Amendment may be executed by electronic signature, which shall be considered as an original signature for all purposes and shall have the same force and effect as an original signature.

SEVENTH AMENDMENT TO AGREEMENT OF LEASE

THIS SEVENTH AMENDMENT TO AGREEMENT OF LEASE (this “Amendment”) is made and entered into as of January 19, 2023 (the “Amendment Effective Date”), by and between CHICAGO KINGSBURY, LLC, a Delaware limited liability company (“Landlord”) and TEMPUS LABS, INC., a Delaware corporation (“Tenant”).

RECITALS

Landlord (as successor in interest to EQC 600 West Chicago, LLC, a Delaware limited liability company) and Tenant are parties to that certain lease dated January 18, 2018 (the “Original Lease”), which lease has been previously amended by First Amendment to Agreement of Lease dated as of January 30, 2018 (the “First Amendment”), by Second Amendment to Agreement of Lease dated as of July 30, 2018 (the “Second Amendment”), by Third Amendment to Agreement of Lease dated as of December 26, 2018 (the “Third Amendment”), by Fourth Amendment to Agreement of Lease dated as of April 23, 2019 (the “Fourth Amendment”), by Fifth Amendment to Agreement of Lease dated as of May 8, 2020 (the “Fifth Amendment”), and by Sixth Amendment to Agreement of Lease dated as of May 4, 2021 (the “Sixth Amendment”) (collectively, the “Lease”). Pursuant to the Lease, Landlord has leased to Tenant space currently containing approximately 180,038 Rentable Square Feet on the 2^nd, 5^th and 7^th floors of the Building located at 600 West Chicago Avenue, Chicago, Illinois (the “Building”) which consists of the space demised in Section 2.1 of the Original Lease, the First Expansion Space and the Third Expansion Space demised in Section 6 of Exhibit G to the Original Lease (as amended), the Fourth Expansion Space demised in the Second Amendment, the Fifth Expansion Space demised in the Third Amendment, the Sixth Expansion Space, the Seventh Expansion Space demised in the Fourth Amendment, the Eighth Expansion Space demised in the Fifth Amendment, and the Ninth Expansion Space demised in the Sixth Amendment (the “Premises”).

Tenant has requested that additional space containing approximately 37,228 Rentable Square Feet on the 5^th floor of the 900 Building shown on Exhibit A attached hereto as the “Tenth Expansion Space” (the “Tenth Expansion Space”) be added to the Premises currently demised under the Lease and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

NOW, THEREFORE, in consideration of the above recitals which by this reference are incorporated herein, the mutual covenants and conditions contained herein and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows:

1.	Tenth Expansion Space and Effective Date.

1.01

Effective on Amendment Effective Date (the “Tenth Expansion Effective Date”), the Premises, as defined in the Lease, is increased by the addition of the Tenth Expansion Space, and from and after the Tenth Expansion Effective Date, the Premises currently demised under the Lease and the Tenth Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease.- The Term for the Tenth Expansion-Space shall-commence on-the Tenth Expansion Effective Date and end on the Expiration Date. The Tenth Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Premises currently demised under the Lease unless such concessions are expressly provided for herein with respect to the Tenth Expansion Space.

1.02

Tenant shall commence payment of Rent with respect to the Tenth Expansion Space on January 1, 2024 (the “Tenth Expansion Rent Commencement Date”). The period of time commencing on the Tenth Expansion Effective Date and continuing until the date immediately preceding the Tenth Expansion Rent Commencement Date is referred to herein as the “Tenth Expansion Build Out

Period”. If Tenant commences Its business operations in the Tenth Expansion Space prior to the last day of the Tenth Expansion Build Out Period, the period of time beginning on the date on which Tenant so commences its business operations in the Tenth Expansion Space and ending on the last day of the Tenth Expansion Build Out Period is referred to as the “Tenth Expansion Beneficial Occupancy Period.” The initial annual Fixed Rent rate per rentable square foot of the Tenth Expansion Space shall be the same as the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease on the Tenth Expansion Rent Commencement Date. The Fixed Rent rate for the Tenth Expansion Space shall increase at such times and in such amounts as the Fixed Rent rate for the initial Premises increases, it being the intent of Landlord and Tenant that the Fixed Rent rate per rentable square foot of the Premises initially demised by the Lease and the Fixed Rent rate per rentable square foot of the Tenth Expansion Space shall be the same. The Tenth Expansion Space shall be delivered to Tenant in its “as is” condition without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements. Any construction, alterations or improvements to the Tenth Expansion Space shall be performed by Tenant at its sole cost and expense and shall be governed in all respects by the terms of the Lease.

1.03

Tenant shall be entitled to receive an improvement allowance (the “Tenth Expansion Space Improvement Allowance”) in an amount equal to $70.00 per rentable square foot of the Tenth Expansion Space. Such Tenth Expansion Space Improvement Allowance shall be applied toward the cost of the improvements to be performed by Tenant in the Tenth Expansion Space (the “Tenth Expansion Space Improvements”). The Tenth Expansion Space Improvement Allowance shall be disbursed in the same manner as described in, and subject to the same terms and conditions of, Sections 7(d), (e), (f) and (g) of the Work Letter attached to the Lease as Exhibit D, except that, for purposes of this Section 1.03, all references to the following terms in Sections 7(d), (e), (f) and (g) of the Work Letter shall instead have the following meanings: (A) “Tenant’s Work” shall instead refer to the “Tenth Expansion Space Improvements.” and (B) “Construction Allowance,” “Separation Work Reimbursement,” “Application Amount” and “Total Allowance” shall instead refer to the “Tenth Expansion Space Improvement Allowance”, Tenant shall reimburse Landlord for the reasonable, actual out-of-pocket costs incurred by Landlord to review plans and specifications for the Tenth Expansion Space Improvements.

1.04

Notwithstanding anything to the contrary contained in Section 7 of the Work Letter attached to the Lease or this Amendment, if (1) the Tenth Expansion Space Improvements have been completed and all costs related thereto have been paid in full, and (2) less than the entire Tenth Expansion Space Improvement Allowance was used (and the portion not used shall be called the “Tenth Expansion Unused Allowance”), then, provided Tenant is not then in default under the Lease, Tenant may request that Landlord apply the portion of the Tenth Expansion Unused Allowance not to exceed $1,302,980.00, or 50% of the Tenth Expansion Space Improvement Allowance, against the next due installments of Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment payable with respect to the Tenth Expansion Space commencing in February, 2025. If Tenant is not able to get the full benefit of such portion of the Tenth Expansion Unused Allowance by applying the same as a credit against Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment as aforesaid for any reason (such as, for example, because the Lease terminates early due to a casualty), then Tenant shall not be entitled to any cash or credit or other compensation of any kind for such portion of the Tenth Expansion Unused Allowance. If Tenant’s general contractor (or Tenant, if applicable) does not submit a request for payment of the entire Tenth Expansion Space Improvement Allowance in accordance with the requirements of this Amendment to Landlord, by December 31, 2024, any portion thereof not requested by such date shall be deemed to be Tenth Expansion Unused Allowance and shall no longer be available to be reimbursed to Tenant and shall automatically be applied against the next due installments of Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment in accordance with the terms of this paragraph. Notwithstanding anything herein to the contrary, Landlord shall not be obligated to allow the Tenth Expansion Unused Allowance to be applied against any portion of the rent for the Tenth Expansion Space during the continuance of an uncured default under the Lease, and Landlord’s obligation to allow such application shall only resume when and if such default is cured.

1.05

Tenant shall be entitled to receive an abatement of 50% of the aggregate of the Fixed Rent, Tenant’s Operating Payment and Tenant’s Tax Payment initially payable with respect to the Tenth Expansion Space (“Tenth Expansion Space First Rental Abatement”) for 12 consecutive months commencing on the Tenth Expansion Effective Date. Such Tenth Expansion Space First Rental Abatement shall be applied toward the first rent due with respect to the Tenth Expansion Space. Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Tenth Expansion Space First Rental Abatement against the rent due in connection with the Tenth Expansion Space if an Event of Default has occurred and is continuing under the Lease.

1.06

In addition to the Tenth Expansion Space First Rental Abatement, Tenant shall be entitled to receive an abatement of 100% of the Fixed Rent only with respect to the Tenth Expansion Space (“Tenth Expansion Space Second Rental Abatement”) for 5 non-consecutive months of January, 2025, January, 2026, January, 2027, January, 2028 and January, 2029 (“Tenth Expansion Space Second Rental Abatement Period”). Such Tenth Expansion Space Second Rental Abatement shall be applied toward the first rent due with respect to the Tenth Expansion Space during each month of the Tenth Expansion Space Second Rental Abatement Period, Notwithstanding anything herein to the contrary, in no event shall Tenant be entitled to apply the Tenth Expansion Space Second Rental Abatement against the rent due in connection with the Tenth Expansion Space if an Event of Default has occurred and is continuing under the Lease, provided if such Event of Default is cured, then Tenant shall again be entitled to apply the Tenth Expansion Space Second Rental Abatement against the rent due in connection with the Tenth Expansion Space and the Tenth Expansion Space Second Rental Abatement Period shall be extended by the period of time that the Tenth Expansion Space Second Rental Abatement was suspended such that Tenant receives the full benefit of the Tenth Expansion Space Second Rental Abatement for the equivalent of the full Tenth Expansion Space Second Rental Abatement Period.

1.07

If Tenant takes possession of or enters the Tenth Expansion Space before the Tenth Expansion Rent Commencement Date, Tenant shall pay for all services requested by Tenant (e.g., freight elevator usage [except as provided in Section 1.08 below] and utilities) and Tenant shall be subject to the terms and conditions of the Lease; provided. however, (i) except for the cost of such services requested by Tenant, Tenant shall not be required to pay Rent for any entry or possession before the Tenth Expansion Rent Commencement Date during which Tenant, with Landlord’s approval, has entered, or is in possession of, the Tenth Expansion Space for the sole purpose of performing improvements or installing furniture, equipment or other personal property, and (ii) during the Tenth Expansion Beneficial Occupancy Period, Tenant shall not be required to pay Rent but shall pay the cost of utilities and janitorial services for the Tenth Expansion Space and for any services specifically requested by Tenant. If Landlord fails to deliver possession of the Tenth Expansion Space to Tenant on the Tenth Expansion Effective Date because of any act or-occurrence beyond the reasonable control of Landlord, including. without limitation, the holding over of any tenants or occupants beyond the expiration of their lease terms. then Landlord shall not be subject to any liability for failure to deliver possession, and such failure to deliver possession shall not affect either the validity of the Lease or the obligations of either Landlord or Tenant thereunder or be construed to extend the expiration of the Term either as to the Tenth Expansion Space or the balance of the Premises; provided, however, that under such circumstances, Landlord shall make reasonable efforts to obtain possession of the Tenth Expansion Space.

1.08

During the performance of the Tenant Expansion Space Improvements and Tenant moving Its furniture, fixtures and equipment into the Tenth Expansion Space, Tenant shall be entitled to use one (1) freight elevator in the 900 Building without charge, except if an elevator operator is required for operation of such freight elevator, Tenant shall reimburse Landlord for the cost of such elevator operator.

Early Termination Payment. As of the Tenth Expansion Effective Date, the Early Termination Payment is estimated to be $11,300,662.99, subject to recalculation after determination of the actual amount of Tenant’s Operating Payments and Tenant’s Tax Payments Included in the rental abatements granted with respect to each portion of the Premises. For the avoidance of doubt, Tenant’s valid exercise of the Termination Option terminates the Lease with respect to the entire Premises effective as of the Early Termination Date set forth in Section 3.01 of Exhibit E to the Lease.

Additional Security Deposit. Landlord is currently holding $250,000.00 as the Security deposit under the Lease. As of the Amendment Effective Date, Tenant shall not be entitled to any further reductions in the Security Deposit and the second and third grammatical paragraphs of Section 2.5 of the Lease are deleted in their entirety.

Space Planning Allowance. In addition to the above described Tenth Expansion Space Improvement Allowance, Landlord, provided Tenant is not in Default, agrees to provide Tenant with a space planning allowance (the “Space Planning Allowance”) in an amount not to exceed the (a) $0.12 per rentable square foot of the Tenth Expansion Space applied toward the cost of the preparation of a preliminary space plan for the Tenth Expansion Space to be prepared by Tenant’s architect, and (b) $0.05 per rentable square foot of the Tenth Expansion Space applied toward the cost of one (1) revision to such a preliminary space plan for the Tenth Expansion Space. If the Space Planning Allowance exceeds the cost of the preparation of the preliminary plan and one (1) revision thereto by Tenant’s architect, any remaining Space Planning Allowance shall accrue to the sole benefit of Landlord, it being agreed that Tenant shall not be entitled to any credit, offset, abatement or payment with respect thereto, The Space Planning Allowance shall be paid to Tenant within 30 days after Tenant’s submission to Landlord of (i) a request for disbursement of the Space Planning Allowance, and (ii) paid invoice and lien waiver from Tenant’s architect in at least the amount of the requested disbursement.
