WHEREAS, Tenant desires to lease an additional 38,400 rentable square feet in the Building as shown on Exhibit A attached hereto (the “Expansion Premises”, which together with the Existing Premises shall be referred to as the “Premises”), and Landlord desires to lease the Expansion Premises to Tenant on the terms set forth herein;

WHEREAS, Tenant’s lease of the Expansion Premises shall commence on May 1, 2013 and expire on May 31, 2022;

WHEREAS, in connection with the lease of the Expansion Premises, the term of the Lease with respect to the Existing Premises shall be extended so that it shall be co-terminus with the Expansion Premises and expire on May, 31, 2022 on the terms set forth herein;

WHEREAS, Landlord and Tenant desire to memorialize their understanding and modify the Lease consistent therewith;

NOW, THEREFORE, and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, Landlord and Tenant hereby agree as follows:

Tenant shall be permitted to occupy the Expansion Premises to install furniture, fixtures and equipment (including wiring and cabling) and perform the Tenant Work (as hereinafter defined) sixty (60) days prior to the Expansion Commencement Date, provided such occupancy is permitted by applicable governmental authorities. If Tenant shall occupy the Expansion Premises prior to the Expansion Commencement Date, Tenant’s occupancy of the Expansion Premises shall be subject to all of the provisions of this Lease except for the payment of rent. Early occupancy of the Expansion Premises shall not advance the expiration date of this Lease.

(a)    Expansion Premises Base Rent. Commencing on the Expansion Commencement Date, Tenant hereby agrees to pay to Landlord monthly installments of Base Rent for the Expansion Premises on the first day of each month in advance, without offset, deduction or prior demand as follows:

5.    Tenant’s Share. The last sentence of Section 4.05 of the Lease is hereby deleted in its entirety. Commencing on the Expansion Commencement Date, Tenant’s Proportionate Share shall be 100%.

9.    Termination Option. Section 3.06 of the Lease is hereby deleted in its entirety and replaced with the following:

“Tenant shall have the one-time conditional right (the “Termination Right”) to terminate this Lease effective on July 31, 2017 (the “Termination Effective Date”), upon Tenant’s strict and complete satisfaction of the all of the following conditions precedent: (a) Tenant shall have delivered to Landlord, not later than January 31, 2017, a written notice (the “Termination Notice”) stating that Tenant elects to exercise this Termination Right and; (b) Tenant shall have paid to Landlord, simultaneously with delivery of its Termination Notice, a termination fee (the “Termination Fee”) equal to the sum of (i) the then unamortized value of the tenant improvements and unamortized brokerage commissions incurred by Landlord in connection with the First Amendment to Lease at 9%, which totals $361,835.52. If Tenant timely delivers the Termination Notice and timely pays the Termination Fee, and further provided Tenant is not in default under this Lease and that no event or condition exists which with notice and the expiration of any grace period would constitute an event of default under this Lease either on the date of Tenant’s delivery of the Termination Notice or on the Termination Effective Date, then this Lease will be terminated effective on the Termination Effective Date. Time is of the essence with respect to the provisions of this Section.”

10.    Security Deposit. The last line of Section 17.16 of the Lease is hereby amended by deleting the words “additional $19,666.66” and substituting the following therefor: “additional $1,185.16”.
