(d)From and after the Termination Date, Landlord and Tenant shall have no further rights, obligations or claims with respect to each other arising under the Lease, except for (i) those obligations of Landlord or Tenant expressly set forth in this Agreement, (ii) the indemnification obligations of Landlord and Tenant under the Lease, which shall survive the Lease in accordance with their respective terms; (iii) the obligations of Landlord and Tenant under Section 4.02 of the Lease with respect to the reconciliation of Operating Costs for the 2021 calendar year (subject to Tenant’s audit right described in Section 4.02(a) of the Lease), which shall be completed by Landlord as soon as reasonably possible following the Termination Date; and (iv) any other terms and provisions of the Lease which expressly survive the expiration or earlier termination of the Lease.

(e)The following conditions shall be conditions precedent to the termination of the Lease in accordance with this Agreement (collectively, the “Termination Conditions”):

(i)Tenant shall have surrendered the Premises on or before the Termination Date in accordance with the terms and conditions of this Agreement and Tenant’s Surrender Obligations (“Tenant’s Surrender Condition”).

(ii)Landlord shall have entered into a new lease amendment with C4 Therapeutics, Inc., a Delaware corporation (“C4”) to lease the Premises on terms and conditions acceptable to Landlord, in Landlord’s sole and absolute discretion (the “C4 Lease Condition”), on or before the Termination Date.

(f)The Termination Conditions are for the sole benefit of Landlord and may, at the sole discretion of Landlord, be waived by Landlord. In the event any of the Termination Conditions have not been fulfilled, or waived in writing by Landlord, by the Termination Date, then Landlord shall have the right to:

-2-

(i)Terminate this Agreement by written notice to Tenant delivered within two (2) Business Days of the Termination Date and, upon such termination, the Lease shall remain, or shall be reinstated, as the case may be, such that the Lease is then in full force and effect and all covenants, conditions and obligations thereunder shall be immediately reinstated; or

(ii)If (A) (x) the C4 Lease Condition is not satisfied on or prior to the Termination Date, (y) Landlord has waived the C4 Lease Condition in writing, and (z) Tenant retains possession of any part of the Premises after the Termination Date, or (B) in the event the Premises are not surrendered in accordance with the terms and conditions of this Agreement on or prior to the Termination Date, then Tenant shall be liable to Landlord for (A) all losses, costs, liabilities and damages which Landlord actually incurs by reason thereof, including, without limitation, reasonable attorneys’ fees, and Tenant shall indemnify, defend and hold harmless Landlord against all claims against Landlord or otherwise resulting from the failure of Tenant to timely vacate and surrender the Premises in accordance with this Agreement, and (B) per diem use and occupancy in respect of the Premises equal to two hundred percent (200%) the Rent payable under the Lease for the period of time immediately prior to the Termination Date (which Landlord and Tenant agree is the Rent to which Landlord would be entitled, is presently contemplated by them as being fair and reasonable under such circumstances and is not a penalty). In no event shall this Section be construed as permitting Tenant to remain in possession of the Premises after the Termination Date.

(iii)If (x) the C4 Lease Condition is satisfied on or prior to the Termination Date and (y) Tenant retains possession of any part of the Premises after the Termination Date, or in the event the Premises are not surrendered in accordance with the terms and conditions of this Agreement on or prior to the Termination Date, then Tenant shall be liable for Landlord for (A) all losses, costs, liabilities and damages which Landlord actually incurs by reason thereof, including, without limitation, reasonable attorneys’ fees, and Tenant shall indemnify, defend and hold harmless Landlord against all claims made by C4, against Landlord or otherwise resulting from the failure of Tenant to timely vacate and surrender the Premises in accordance with this Agreement and the Lease, and (B) per diem use and occupancy in respect of the Premises equal to two hundred percent (200%) the Rent payable under the Lease for the period of time immediately prior to the Termination Date (which Landlord and Tenant agree is the Rent to which Landlord would be entitled, is presently contemplated by them as being fair and reasonable under such circumstances and is not a penalty). In no event shall this Section be construed as permitting Tenant to remain in possession of the Premises after the Termination Date.

(g)In the event the C4 Lease Condition has not been satisfied on or prior to the Termination Date, Landlord shall have the right, within two (2) Business Days after the Termination Date to notify Tenant (the “C4 Lease Condition Notice”) in writing that Landlord elects to either (x) waive the C4 Lease Condition, or (y) terminate this Agreement and, upon such termination, the Lease shall remain in full force and effect and all covenants, conditions and obligations thereunder shall be immediately reinstated. In the event Landlord has not delivered the C4 Lease Condition Notice to Tenant of its election to exercise its termination right in

-3-

accordance with the terms of this Section 2(g), then Landlord shall be deemed to have waived the C4 Lease Condition and its termination right set forth in Section 2(g).

3.Security Deposit.

(a)Landlord and Tenant hereby acknowledge and agree that Landlord is holding, as the Security Deposit under the Lease, a Letter of Credit in the amount of Two Million Forty-Two Thousand Three Hundred Twenty-Eight and No/100 Dollars ($2,042,328.00) the (“Security Deposit”). The terms and conditions of Article 14 of the Lease shall govern and control Landlord’s return of the Security Deposit to Tenant; provided however, that the ninety (90) day period for the return of the Security Deposit is shortened to thirty (30) days from and after the Termination Date, provided that Tenant complies with all terms and conditions of this Agreement.

(b)Following Tenant’s receipt of the Security Deposit, Tenant hereby releases and discharges all Landlord Parties (as defined below) from any and all claims, causes of action, suits, debts, complaints, judgments, expenses, attorneys’ fees, costs, demands, contracts, warranties, errors, omissions, representations, claims for money, claims for equitable relief and all other claims of any nature whatsoever, whether such claims have accrued or will accrue in connection with the Security Deposit.

(a)Subject to the satisfaction of the C4 Lease Condition, as of the Termination Date, Landlord and Tenant hereby acknowledge and agree that Tenant has agreed to transfer to C4 Therapeutics, Inc., a Delaware corporation (“C4”) all of the personal property, trade fixtures, equipment and furniture in the Premises (the “Transferred Property”), pursuant to a certain Bill of Sale, in substantially the same form as attached hereto as Exhibit C (the “Bill of Sale”). Notwithstanding the foregoing, the Transferred Property shall not include those items listed on Exhibit D attached hereto (the “Excluded Items”). Following the Termination Date, Tenant shall be permitted to leave the Transferred Property in the Premises and the Transferred Property shall be deemed the property of C4.

(b)Notwithstanding Section 4(a) above, except for the Transferred Property, Tenant shall remove all of Tenant’s Property (as defined in the Lease), including, without limitation, the Excluded Items, from the Premises on or before the Termination Date. Prior to the Termination Date, Tenant shall, at Tenant’s sole cost and expense, satisfy Tenant’s Surrender Obligations and repair all damage to the Premises, the roof, or any portion of the Building and the Common Areas caused by the satisfaction of Tenant’s Surrender Obligations. Notwithstanding anything contained herein to the contrary, (i) Tenant shall not be required to remove the Generator and, subject to the satisfaction of the C4 Lease Condition, Tenant shall transfer ownership of the Generator, and all natural gas or fuel supplies and tanks, all cabling and all other related appurtenances, to C4, and such items, including the Generator, shall be deemed Transferred Property, and (ii) Tenant shall not be required to remove any HVAC equipment and Tenant shall transfer ownership of the HVAC equipment to Landlord. In the event Tenant fails to

-4-

make such repairs within five (5) days after notice from Landlord to Tenant, Landlord may, in Landlord’s sole discretion, elect to make such repairs on behalf of Tenant and Tenant shall reimburse Landlord for all reasonable costs actually incurred by Landlord in making such repairs. In the alternative, Landlord may deduct from the Termination Payment or the Security Deposit, at Landlord’s election, the cost of such repairs.

(c)Any of Tenant’s Property in, on or attached to the Premises and remaining in or on the Premises after the Termination Date (other than the Transferred Property), shall be deemed to be abandoned by Tenant (such property being referred to as “Abandoned Property”), and Landlord may dispose of the Abandoned Property as it, in its sole discretion, deems appropriate.  Tenant shall not be entitled to any proceeds received by Landlord as a result of the disposition of the Abandoned Property and Tenant shall be obligated for any reasonable costs actually associated with the Landlord’s disposition of the Abandoned Property. Tenant shall reimburse Landlord for all such costs within ten (10) days of Landlord’s demand. In the alternative, Landlord may deduct from the Termination Payment or the Security Deposit, at Landlord’s election, the costs associated with the Landlord’s disposition of the Abandoned Property.

(d)Tenant shall indemnify, defend, and hold Landlord harmless from and against any losses, costs, claims, damages, and liabilities, including, without limitation, reasonable attorneys’ fees and expenses incurred by Landlord arising out of or resulting from any liens or encumbrances on the Transferred Property (but only to the extent the same arose during Tenant’s period of ownership).
