TERMINATION OPTION

 

1.             If, and only if, after the April 30, 2024, Lessee requests in writing to expand the Premises by leasing additional space in the Building
(an “Expansion Request”), and Lessor cannot reasonably accommodate such Expansion Request within ninety (90)
days after Lessor’s receipt of the Expansion Request, Lessee shall have the one-time option (the “Termination Option”)
to terminate this Lease as to the entire Premises, said termination to be effective (the “Termination Date”)
90 days after the date of the Termination Notice (defined below). The Expansion Request must include the amount of additional rentable
square footage Lessee desires to lease in the Building. As used herein, the words “reasonably accommodate” means that Lessor
cannot or will not lease to Lessee at least 95% of the rentable square footage requested by Lessee in the Expansion Request. For the avoidance
of doubt, Lessee shall not have any Termination Option for an Expansion Request given prior to May 1, 2024.

 

2.            The Termination Option may be exercisable by Lessee and will be effective only if, upon the date of the Termination Notice, and upon the
day immediately prior to the Termination Date there is no default by Lessee under this Lease. The Termination Option is personal to the
originally Lessee named in this Lease, and without the prior, written consent of Lessor, shall not be assigned or transferred to any person
or entity other than the original Lessee, and any transfer in violation hereof shall be null and void.

 

3.            The Termination Option is subject to each of the following requirements (any of which Lessor may waive in writing in its sole and absolute
discretion):

 

a.           
Lessee must provide written notice (the “Termination Notice”) to Lessor of Lessee’s exercise of the Termination
Option no earlier than ninety (90) days. The Termination Notice, once provided to Lessor, shall be irrevocable.

 

b.           
Lessee must pay to Lessor the Termination Payment. The “Termination Payment” shall be (i) a cash payment equal
to 3 months of Base Rent and Additional Rent, if applicable, plus (ii) forfeiture of Lessee’s security deposit under the Lease.
The Termination Payment shall be made at the same time as the Termination Notice. The Termination Payment is not a prepayment of rent
under the Lease but is separate consideration for the Termination Option; and Lessee must continue to pay all rent under the Lease following
the Termination Notice up to and including the Termination Date.

 

4.             Lessee must comply with all provisions of this Lease with respect to the expiration or termination of this Lease and surrender of the
Premises. Any holdover by Lessee in all or any portion of the Premises after the Termination Date shall be a default by Lessee under this
Lease and will be subject to the holdover provisions of this Lease.

 

     

     

    

 

5.           
Lessee shall continue to perform all of Lessee’s obligations under the Lease for the period up to and including the Termination
Date, including, without limitation, the obligation to pay all rent and any other costs or charges for the period up to and including
the Termination Date. Any provision of this Lease which is intended to survive the expiration or termination of this Lease shall survive
the Termination Date.

 

6.           
With respect to all dates for exercising any rights and the performance of any obligations in connection with the exercise or implementation
of this Termination Option, time shall be of the essence.

 

7.           
As of the date Lessee provides Lessor with a Termination Notice, any unexercised rights or options of Lessee to extend or renew the Term
or to expand the Premises (whether expansion options, rights of refusal, rights of offer, or other similar rights), and any outstanding
Lessee improvement allowance, rental abatement, or other allowance or credits not claimed and properly utilized by Lessee in accordance
with this Lease as of such date, shall immediately be deemed terminated and no longer available or of any further force or effect.

 

8.           
If at any time after a Termination Notice, up to and including the Termination Date, default occurs, then Lessor may elect, but is not
obligated, by written notice given to Lessee to cancel and declare null and void Lessee’s exercise of the Termination Option, and
this Lease shall continue in full force and effect for the full Term hereof unaffected by Lessee’s exercise of the Termination Option.EX-4.4.1

Warrant Agreement as if ReNew Global had been the original party thereto. 

  

	 	(b)	 Computershare shall be substituted for Continental in the Warrant Agreement and shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally named as warrant agent under the Warrant Agreement; provided that, in no event shall Computershare be liable for the actions or omissions of Continental under the Warrant
Agreement. Computershare undertakes full performance of the Warrant Agreement in the place of Continental.

original, but all of which together shall constitute one and the same instrument. Execution and delivery of this Agreement by email or exchange of facsimile copies bearing the facsimile signature of a party hereto shall constitute a valid and
binding execution and delivery of this Agreement by such party.

benefit of each party’s respective successors and assigns.
