Total costs and expenses for the third quarter of 2009 were $48.5 million, which included $7.7 million of stock-based compensation expenses and $0.1 million for previous stock-based compensation restatement and related legal expenses. This is compared to total costs and expenses of $49.3 million for the second quarter of 2009, which included $7.9 million of stock-based compensation expenses and a net recovery of $0.4 million for previous stock-based compensation restatement and related legal expenses. General litigation expenses for the third quarter were $12.0 million, a decrease of $3.0 million from the second quarter of 2009. Total costs and expenses in the third quarter of last year were $60.0 million, which included $9.0 million of stock-based compensation expenses, $4.0 million of restructuring-related expenses, $2.2 million of asset impairment expenses and $0.4 million of previous stock-based compensation restatement and related legal expenses. General litigation expenses in the third quarter of 2009 decreased $3.7 million from the third quarter of 2008.

Total costs and expenses for the nine months ended September 30, 2009 were $141.4 million, which included $24.0 million of stock-based compensation expenses and a net recovery of $14.0 million for previous stock-based compensation restatement and related legal expenses.

Interest and other expense, net, for the third quarter of 2009 was $6.8 million as compared to $1.6 million in the second quarter of 2009 and $0.3 million in the third quarter of 2008. Interest and other expense, net, for the nine months ended September 30, 2009 was $9.6 million as compared to interest income of $1.4 million for the same period of 2008. Prior periods have been adjusted to reflect the impact of the adoption on January 1, 2009 of a FASB staff position which clarifies the accounting for convertible debt instruments that may be settled in cash upon conversion, including partial cash settlement. The Company has retrospectively adjusted the income statement to include non-cash interest expense of $3.0 million for the third quarter of 2008 and $8.8 million for nine months ended September 30, 2008.

Net loss for the third quarter of 2009 was $27.5 million as compared to a net loss of $24.0 million in the second quarter of 2009 and a net loss of $30.9 million (adjusted for adoption of the FASB staff position) in the third quarter of 2008. Net loss per share for the third quarter of 2009 was $0.26 as compared to a net loss per share of $0.23 in the second quarter of 2009 and a net loss per share of $0.29 (adjusted for adoption of the FASB staff position) for the third quarter of 2008. Net loss for the nine months ended September 30, 2009 was $68.9 million as compared to a net loss of $183.6 million (adjusted for adoption of the FASB staff position) for the same period of 2008. Net loss per share for the nine months ended September 30, 2009 was $0.66 as compared to a net loss per share of $1.75 (adjusted for adoption of the FASB staff position) in the same period of 2008.

Cash, cash equivalents, and marketable securities as of September 30, 2009 were $498.5 million, up approximately $18.1 million from June 30, 2009 and up approximately $152.6 million from December 31, 2008. During the third quarter of 2009, the Company issued an additional $22.5 million aggregate principal amount of 5% Convertible Senior Notes due 2014 as a result of the underwriters exercising their overallotment option related to the 2014 Notes. During the nine months ended September 30, 2009, the Company received approximately $168.2 million net proceeds related to the issuance of the 5% Convertible Senior Notes, $7.3 million of insurance proceeds related to reimbursement claims associated with the stock option investigation and derivative lawsuits as well as $4.5 million from former executives due to the resolution of the derivative lawsuits.

The convertible notes are carried at face value less the debt discount associated with the adoption of the FASB staff position for the periods presented. As such, the carrying value of the convertible notes as of December 31, 2008 has been retrospectively adjusted to reflect the impact of the adoption of the FASB staff position.

The conference call discussing third quarter 2009 results will be webcast live via the Rambus Investor Relations website (http://investor.rambus.com) at 2:00 p.m. Pacific Time today.
