NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

4. Long Term Lease; Suite 525 Commencement Date; Expansion Commencement Date. Notwithstanding anything to the contrary in the Long Term Lease, the Suite 525 Commencement Date shall occur on the Expansion Commencement Date so that the entire fifth (5^th) floor of the 3611 Building commences on the same date, which date is anticipated to be November 1, 2020. Tenant shall have the right to occupy the Expansion Premises (i.e., the entire fifth (5^th) floor of the 3611 Building) for the conduct of Tenant's business following the Suite 525 Expiration Date and prior to the Expansion Commencement Date, provided that all of the terms and conditions of the Long Term Lease, as hereby amended, shall apply, other than Tenant's obligation to pay Base Rent and Direct Expenses. Effective as of the Expansion Commencement Date, Tenant shall be obligated to pay Base Rent and Direct Expenses for the Expansion Premises (i.e., the entire fifth (5^th) floor of the 3611 Building) in accordance with Sections 3.2 and 3.3 of the Long Term First Amendment, subject to the Expansion Base Rent Abatement as provided in Section 3.4 of the Long Term First Amendment.

Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including, without limitation, reasonable attorneys' fees) with

respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party's dealings with any real estate broker or agent, including the Broker, in connection with this Amendment. The terms of this Section 5 shall survive the expiration or earlier termination of this Amendment.

6. Signatures. The parties hereto consent and agree that this Amendment may be signed and/or transmitted by facsimile, e-mail of a .pdf document or using electronic signature technology (e.g., via DocuSign or similar electronic signature technology), and that such signed electronic record shall be valid and as effective to bind the party so signing as a paper copy bearing such party’s handwritten signature. The parties further consent and agree that (1) to the extent a party signs this Amendment using electronic signature technology, by clicking “SIGN”, such party is signing this Amendment electronically, and (2) the electronic signatures appearing on this Amendment shall be treated, for purposes of validity, enforceability and admissibility, the same as handwritten signatures.
