This press release contains a forward-looking statement regarding expected growth in non-GAAP EPS for 2007. Such statement is a prediction and involves risks and uncertainties such that the actual result may differ materially. Among other factors, growth in non-GAAP EPS could be affected by unexpected safety, efficacy or manufacturing issues, additional time requirements for BLA preparation or decision making, need for additional data or clinical studies, FDA actions or delays, the failure to obtain or maintain FDA approval, changes in dosing or duration of product use, competition, pricing, reimbursement, intellectual property or contract rights, the ability to supply product, product withdrawals, new product approvals and launches, product sales, contract revenues and royalties, cost of sales, R&D or MG&A expenses, stock-based compensation expense, unanticipated expenses such as litigation or legal settlement expenses or equity securities write-downs, fluctuations in tax and interest rates, and changes in accounting or tax laws or the interpretation of such laws. Please also refer to Genentech's periodic reports filed with the Securities and Exchange Commission. Genentech disclaims, and does not undertake, any obligation to update or revise the forward-looking statement in this press release.

¹ Genentech's non-GAAP operating revenues exclude recognition of deferred royalty revenue associated with the acquisition of Tanox, Inc. Genentech's non-GAAP net income and non-GAAP earnings per share exclude the after-tax impact of certain items associated with the acquisition of Tanox, Inc., including in-process research and development expenses (a non-recurring expense in the third quarter of 2007), recurring recognition of deferred royalty revenue, recurring amortization of intangible assets, and a gain pursuant to Emerging Issues Task Force (EITF) issue no. 04-1 (a non-recurring gain in the third quarter of 2007). Non-GAAP net income and non-GAAP earnings per share also exclude recurring charges related to the 1999 redemption of Genentech's stock by Roche Holdings, Inc., litigation-related special items, and employee stock-based compensation expense. The differences in non-GAAP and GAAP numbers, including expected 2007 earnings per share, are reconciled in the accompanying tables and on http://www.gene.com.

² Genentech's non-GAAP reported COS, R&D and MG&A expenses exclude the effects of employee stock-based compensation expense associated with Genentech's adoption of FAS 123R on January 1, 2006. Stock-based compensation expense was recognized in COS for the first time in the first quarter of 2007 as the company capitalized employee stock-based compensation into inventory produced in 2006 and began to sell those products in 2007. The differences in non-GAAP and GAAP numbers are reconciled in the accompanying tables and on http://www.gene.com.
