IN WITNESS WHEREOF, Landlord and Tenant, acting herein by duly authorized individuals, have caused these presents to be executed as of the Effective Date set forth herein.

(a)    Provided that as of the rime of the giving of the Renewal Notice and the Commencement Date of the Renewal Term, (i) Tenant is the Tenant originally named herein, (ii) Tenant actually occupies all of the Premises initially demised under this Lease and any space added to the Premises, and (iii) no event of default exists or would exist but for the passage of time or the giving of notice, or both; then Tenant shall have the right to extend the Lease Term for an additional term of twelve (12) months (such additional term is hereinafter called the “Renewal Term”) commencing on the day following the expiration of the Extension Term (hereinafter referred to as the “Commencement Date of the Renewal Term”). Tenant must give Landlord notice (hereinafter called the “Renewal Notice”) of its election to extend the term of the Lease Term at least nine (9) months, but not more than twelve (12) months, prior to the scheduled expiration date of the Lease Term.

(b)    The Basic Annual Rent payable by Tenant to Landlord during the Renewal Term shall be the sum of $181,074.00 per month (which is equal to $36.00 per square foot of Rentable Area); provided, however, in the event the Premises have been expanded (including pursuant to the Right of First Offer under Exhibit B hereof), then the monthly installment for the Renewal Term shall be adjusted accordingly in order to reflect the additional Rentable Area then being included in the Premises.

(c)    The payment of Basic Annual Rent does not reduce the Tenant’s obligation to pay or reimburse Landlord for Operating Costs and other reimbursable items as set forth in the Lease, and Tenant shall reimburse and pay Landlord as set forth in the Lease with respect to such Operating Costs and other items with respect to the Premises during the Renewal Term (it being acknowledged and agreed that during the Renewal Term the Base Year shall continue to be the calendar year 2016).

(d)    Except for the Basic Annual Rent during the Renewal Term as specified above, Tenant’s occupancy of the Premises during the Renewal Term shall be on the same terms and conditions as are in effect immediately prior to the expiration of the initial Lease Term; provided, however, Tenant shall have no further right to any allowances, credits or abatements or any options to expand, contract, renew or extend the Lease.

(h)    If Tenant exercises its right to extend the term of the Lease for the Renewal Term pursuant to this Addendum One, the term “Lease Term” as used in the Lease, shall be construed to include, when practicable, the Renewal Term, as applicable, except as provided in (d) above.

(a)    “Offered Space” shall mean the following suites: (i) that certain 16,824 square feet of Rentable Area designated as Suite 100 and 150 in the Building (which such Suite 100 contains 3,614 usable square feet and such Suite 150 contains 5,395 usable square feet) (the “Suite 100/150 Spaces”), (ii) that certain 6,230 square feet of Rentable Area (5,395 usable square feet) designated as Suite 190 in the Building (being the “Suite 190 Offered Space:” collectively with the Suite 100/150 Spaces being the “First Floor Offered Space”)), (iii) that certain 26,982 square feet of Rentable Area designated as Suite 500 in the Building, (iv) that certain 11,181 square feet of Rentable Area designated as Suite 300 in the Building, (v) that certain 8,227 square feet of Rentable Area designated as Suite 340 in the Building, (vi) that certain 4,298 square feet of Rentable Area designated as Suite 325 in the Building, and (vii) that certain 5,850 square feet of Rentable Area designated as Suite 330 in the Building.

(b)    Provided that as of the date of the giving of the First Offer Notice, (i) Tenant is the Tenant originally named herein, (ii) Tenant actually occupies all of the Premises originally demised under this Lease and any premises added to the Premises, and (iii) no event of default or event which but for the passage of time or the giving of notice, or both, would constitute an event of default has occurred and is continuing, if at any time during the Lease Term any portion of the Offered Space is vacant and unencumbered by any rights of any third party, then Landlord, before offering such Offered Space to anyone, other than the tenant then occupying such space (or its affiliates), shall offer to Tenant the right to include the Offered Space within the Premises on the same terms and conditions upon which Landlord intends to offer the Offered Space for lease. Notwithstanding anything to the contrary in the Lease, the right of first offer granted to Tenant under this Exhibit B shall be subject and subordinate to (i) the rights of all tenants at the Project under existing leases, and (ii) the herein reserved right of Landlord to renew or extend the term of any lease with the tenant then occupying such space (or any of its affiliates), whether pursuant to a renewal or extension option in such lease or otherwise.

In addition, if Landlord desires to lease more than just the Offered Space to one tenant, Landlord may offer to Tenant pursuant to the terms hereof all such space which Landlord desires to lease, and Tenant must exercise its rights hereunder with respect to all such space and may not insist on receiving an offer for just the Offered Space.

(e)    If Tenant does not accept (or fails to timely accept) an offer made by Landlord pursuant to the provisions of this Exhibit B with respect to the Offered Space designated in the First Offer Notice, then Landlord shall be under no further obligation with respect to such space by reason of this Exhibit B, Additionally, if Tenant timely accepts such offer and fails to execute the ROFO Amendment (defined below) within thirty (30) days after the delivery of the First Offer Notice, then, at Landlord’s sole option, Landlord shall be under no further obligation with respect to such space by reason of this Exhibit B.

(f)    In the event that Tenant exercises its rights to any Offered Space pursuant to this Exhibit B, then Landlord shall prepare, and Tenant shall execute, an amendment to the Lease which confirms such expansion of the Premises and the other provisions applicable thereto (the “ROFO Amendment”).
