Option to Extend 15.1 So long as Adept Technology, Inc., a California corporation (or its Permitted Assignee, as defined in Section 7.2), is the Tenant hereunder and occupies the entirety of the Leased Premises, and subject to the condition set forth in clause (b) below, Tenant shall have one option to extend the term of this Lease with respect to the entirety of the Leased Premises, for a period of five (5) years from the expiration of the initial Lease Term (the "Extension Period"), subject to the following conditions: (a) The option to extend shall be exercised, if at all, by notice of exercise given to Landlord by Tenant not more than fifteen months nor less than nine months prior to the expiration of the initial Lease Term; (b) Anything herein to the contrary notwithstanding, if Tenant is in default under any of the monetary or material non-monetary terms, covenants or conditions of this Lease, either at the time Tenant exercises the extension option or on the commencement date of the Extension Period, Landlord shall have, in addition to all of Landlord's other rights and remedies provided in this Lease, the right to terminate such option to extend upon notice to Tenant. 15.2 In the event the option is exercised in a timely fashion, the Lease shall be extended for the term of the Extension Period upon all of the terms and conditions of this Lease, provided that the Base Monthly Rent for the Extension Period shall be the "Fair Market Rent" for the Leased Premises, increased annually on each anniversary of the commencement date of the Extension Period to reflect the change in the Consumer Price Index for the San Francisco Metropolitan Area, All Items (the "CPI"), for the twelve (12) month period ending sixty (60) days prior to the subject adjustment date, but in no event shall Base Monthly Rent be increased less than 4.00% per annum, nor more than 7.00% per annum for such twelve (12) month period. Base Monthly Rent shall be so adjusted at the end of each twelve (12) month period during the Lease Term. For purposes hereof, "Fair Market Rent" shall mean the Base Monthly Rent determined pursuant to the process described below. In no event, however, shall any adjustment of Base Monthly Rent pursuant to this paragraph result in a decrease of the Base Monthly Rent for the Premises below the amount due from Tenant for the preceding portion of the initial Lease Term for which Base Monthly Rent had been fixed.
