Item 1.02 Termination of a Material Definitive Agreement.

On April 26, 2012, NetApp, Inc. (“NetApp”) terminated one of its existing synthetic leasing arrangements with BNP Paribas Leasing Corporation (“BNPPLC”) for the Moffett Business Center in Sunnyvale, California (the “Property”) by exercising its option under the Purchase Agreement (as defined below) to purchase the Property from BNPPLC. Prior to the termination of the arrangement, NetApp leased the Property from BNPPLC for a term expiring in December 2012. In connection with the termination, NetApp repaid the outstanding lease balance of approximately $80 million and purchased the Property. As a result of the termination, NetApp incurred a total loss of approximately $36 million, which is the difference between the lease obligation of approximately $80 million and the Property’s fair value of approximately $44 million, determined at the date of termination. A $32 million loss had been accrued prior to the date of the lease termination and, as a result, NetApp will record an additional lease termination loss of approximately $4 million in the fourth quarter of fiscal 2012. BNPPLC’s rights, title and interest in and to the Synthetic Lease Agreements (as defined below) were terminated and reverted back to NetApp. NetApp’s future real estate lease payments will be reduced by a total of approximately $80 million for the lease periods through fiscal 2013. No early termination penalties were incurred by NetApp as a result of this termination.

The term “Synthetic Lease Agreements” used herein includes the following agreements between NetApp and BNPPLC that reflect the synthetic leasing arrangement for the Property, all of which have been previously filed:

Item 2.04 Triggering Events That Accelerate or Increase a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement.

The disclosure provided in Item 1.02 “Termination of a Material Definitive Agreement” is incorporated by reference into this Item 2.04 as if fully set forth herein.
