Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On November 30, 2012, Zipcar, Inc. (the “Company”) entered into an Office Lease Agreement (the “Lease Agreement”), with Farnsworth Stillings L.P. (“Lessor”) pursuant to which the Company has agreed to lease a 46,200 square foot building located at 35 Thomson Place in Boston, Massachusetts to be used for office space for the Company’s corporate headquarters (the “Leased Property”). The Company intends to move all of its operations currently conducted at 25 First Street, Cambridge, Massachusetts to the Leased Property.

The term of the Lease Agreement commences on November 30, 2012 (the “Commencement Date”) and rent payments will commence on September 1, 2013. The Lease Agreement expires on December 31, 2023. The Company has the option to extend the term of the Lease Agreement for two additional five-year periods upon the Company’s written notice to the Lessor at least 18 months but no more than 21 months in advance of the extension. The Company has the option to assign the Lease Agreement or sublet a portion or all of the Leased Property under certain circumstances.

The total cash obligation for the base rent over the initial term of the Lease Agreement is approximately $18.5 million. In addition to the base rent, the Company is also responsible for a share of operating expenses and real estate taxes, in accordance with the terms of the Lease Agreement. To secure the Company’s obligations under the Lease Agreement, the Company will provide a security deposit in the amount of $894,201 to the Lessor, which may be reduced to $596,134 on September 1, 2018 and to $298,067 on September 1, 2019. The Lessor has agreed to pay up to $1,155,000 for certain upgrades and alterations to be made to the Leased Property.

If the Company is considered in default under the terms of the Lease Agreement (a “Default”) and fails to cure such Default in the applicable time period prescribed under the Lease Agreement, the Lessor may terminate the Lease Agreement and the Company will be required to pay the difference between the remaining rent payments through the expiration of the Lease Agreement and any rental income from reletting the Leased Property over such time period, after deducting any expenses incurred in connection with such reletting. Circumstances that may be considered a Default under the Lease Agreement include the failure to timely pay any rent, failure to comply with any term, provision, condition or covenant of the Lease Agreement and the insolvency of the Company.

The foregoing is a summary of the Lease Agreement and is qualified in its entirety by reference to the Lease Agreement, a copy of which is attached hereto as Exhibit 10.1 and is incorporated into this Item 1.01 by reference.
