E.             Landlord and Tenant desire to amend the Lease and reflect the lease by Landlord to Tenant of all such expansion space, subject to the terms and conditions hereinafter set fourth.

NOW, THEREFORE, for good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

The Second Additional Space is leased for a lease tern commencing on August 1, 2007, and expiring on February 28, 2019, unless sooner terminated as provided in the Lease and subject to renewal as provided in Paragraph 2(e) below. Tenant may take occupancy of the Second Additional Space on or after the full execution of this Second Amendment. The Second Additional Space is leased upon all of the same terms and provisions as are contained in the Lease, except as otherwise provided in this Second Amendment or as may be inconsistent with the provisions of this Second Amendment. From and after the full execution of this Second Amendment, all references in the Lease to “Premises” shall mean and refer to the Original Premises, the First Additional Space, and the Second Additional Space, collectively.

(b)   Effective as of August 1, 2007, Tenant shall pay Base Rent for the Second Additional Space in the following amounts for the following periods:

(d)   Landlord shall not be obligated to improve or, subject to Paragraph 2(g) below, provide Tenant with any allowance to improve, the Second Additional space.  By taking possession of the Second Additional Space hereunder, Tenant accepts the Second Additional Space as being in good order, condition and repair otherwise “As-Is”, “Where-Is” and will all faults, known and unknown.

(e)   Section 28.4 of the Lease shall apply to the Second Additional Space,   and Tenant shall have two (2) options to extend the Term for the Second Additional Space for five (5) years each, and, subject 2(g) below, the Base Rent payable for the Second Additional Space shall continue to increase during the applicable renewal term at the annual rate of $0.50 per rentable square foot of the Second Additional Space.
