NOW, THEREFORE, in consideration of the premises, the rental payments, covenants and conditions set forth herein, and such other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by each of the parties hereto, Sublessor and Sublessee hereby agree as follows:

1.Sublease Premises. Sublessor hereby subleases to Sublessee, and Sublessee hereby subleases from Sublessor, on the terms and conditions set forth in this Sublease, all of Sublessor's right, title and interest in and to the Sublease Premises. For the removal of any doubt, the Sublease Premises will include the entire second floor of the Building and a non-exclusive right to use the common areas within the Building, including access to server rooms and IT closets.

2.Relocation Rent Credit. Sublessor shall provide to Sublessee a credit (the "Relocation Rent Credit") equal to all actual, necessary and reasonably documented expenses Sublessee incurs to third

Upon reasonable request, Sublessee shall provide reasonable detail of expenses used as a Relocation Rent Credit. The Relocation Rent Credit shall be applied against Base Rent first becoming due under this Sublease, and Sublessee shall not be obligated to make payments of Base Rent until the Relocation Rent Credit has been fully exhausted. Thereafter, Base Rent shall be due and payable in accordance with the terms of this Sublease. For avoidance of doubt, the intent is that Sublessee will break even financially on account of this Sublease, with all of its moving related expenses recouped through the Relocation Rent Credit. In addition, Sublessor shall provide a tenant improvement allowance of up to [***] to Sublessee. Sublessee shall cooperate with Sublessor to request and receive approval from the CLO for any such tenant improvements.

(b)Sublessor herby grants to Sublessee an option to extend the Term through the Termination Date under the 2017 Lease, which is April 30, 2028, ("Extended Term") at the same Rent and other terms of this Sublease Agreement, except that Sublessee shall not be provided a Relocation Rent Credit or a tenant improvement allowance during the Extended Term. If this option is exercised the "Term" shall include the "Extended Term".

(c)Should Sublessee continue to hold the Sublease Premises after the termination of this Sublease, whether the termination occurs by lapse of time or otherwise, such holding over shall constitute and be construed as a month-to-month subtenancy.

It is expressly provided, however, that this Section 3(c) shall not in


Page 2 of 8



any sense constitute the grant to Sublessee of any option to extend the Sublease Term, other than the option for the Extended Term granted in Section 3(b) above.

4.Rent. During the Term of this Sublease, including the Extend Term if Sublessee exercises its option, the Sublessee shall pay to Sublessor Base Rent (the "Rent") in the amount of [***], payable in monthly installments of [***] per month, each payable in advance on the first (1st) day of each month during the Term of this Sublease beginning on June 1, 2026 (subject to the Relocation Rent Credit) and continuing on the first day of each month thereafter without notice or demand.
