Notes:

1. The Debtors maintain their accounting records and prepare financial statements on a consolidated basis only. This modified presentation reflects cash basis payroll of the subsidiary entities, which is funded by Dendreon Corp.

2. The Debtors’ consolidated statement of operations reflects an allocation of payroll expenses among several operating expense categories (i.e., Cost of Product Revenue, R&D and SG&A). For the purpose of presenting payroll by entity without double-counting of such expenses, the cash basis payroll must be deducted before being included separately

3. Payroll Expense (noted above) includes payroll, payroll taxes and 401(k). These amounts are funded to ADP via the US Bank Operating account. For taxation purposes, each legal entity pays separate state employment taxes for the states in which it operates
