The Amendment also extends the term of the Agreement to December 31, 2019, with an additional two-year automatic renewal period unless the Company or EPMP provides notice of its intent not to renew prior to the commencement of such renewal term. The Amendment further provides the Company with the right to place a final order with EPMP following termination of the Agreement, as amended and modifies certain warranty and assignment terms and the parties’ limitations of liability.

Lease Agreement

On March 5, 2015, the Company entered into a Lease Agreement (the “Lease”) with Westport Office Park, LLC (the “Landlord”) to lease approximately 50,470 square feet of office space located at 1800 Bridge Parkway, Redwood City, California 94065 (the “Premises”) for the Company’s new principal executive offices.

The Company has an option to extend the Lease Term for an additional five years (the “Option Term”), subject to certain conditions, upon written notice to the Landlord.

The Lease provides for annual base rent of approximately $2.0 million in the first year of the Lease Term, which increases on a yearly basis up to approximately $2.4 million for the final year of the Lease Term. The Lease also provides for certain limited rent abatements in the second year of the Lease Term.

The Lease provides for annual base rent during the Option Term to be calculated based on a ratable portion fair market rental value as described in the Lease.

The Company will be entitled to a one-time improvement allowance of approximately $2.3 million for costs related to the design and construction of Company improvements that are permanently affixed to the Premises.

The Company has obtained a standby letter of credit (the “Letter of Credit”) in the amount of approximately $0.6 million, which may be drawn down by the Landlord to be applied for certain purposes upon the occurrence of certain events under the Lease, including the Company’s failure to pay amounts due under the Lease within the applicable notice and cure periods and the Company’s voluntary or involuntary bankruptcy, receivership or conservatorship. The Company must increase the amount of the Letter of Credit to approximately $1.2 million in the event that the Company does not receive full approval from the U.S. Food and Drug Administration for its Senza^® spinal cord stimulation system by December 31, 2015.
