TABLE OF CONTENTS

ITEM 1.01 Entry into a Material Definitive Agreement

On January 6, 2006, Advent Software, Inc. (the “Company”) entered into a definitive lease agreement with Toda Development, Inc. (the “Landlord”) whereby the Company will lease approximately 95,000 square feet of office space at 600 Townsend Street in San Francisco, California. The Company’s contractual operating lease obligation under this agreement is approximately $20 million, payable over the ten-year term of the lease. Additionally, the Company anticipates approximately $7.6 million of leasehold improvements, of which $3.8 million will be funded by the Landlord and approximately $3.8 million will be paid directly by Advent. The rental period under the Lease commences 10 days after substantial completion of the tenant improvements by the Landlord. After delivery of the improved premises, currently estimated by Landlord’s general contractor to be in the third fiscal quarter of 2006, the Company will exit its current corporate headquarter facilities and relocate to the 600 Townsend facility. The leases on the current facilities expire on December 31, 2006 and October 31, 2008. Advent therefore anticipates incurring a restructuring charge, principally related to the lease expiring on October 31, 2008, when the Company relocates to the 600 Townsend facility.
