Related Party Transaction, Description of Transaction	Since December 2004, CRBCI and Counsel have entered into successive annual management services agreements (the “Agreement”). Under the terms of the Agreement, CRBCI agrees to pay Counsel for ongoing services provided to CRBCI by Counsel personnel. These services include preparation of the Company’s financial statements and regulatory filings, taxation matters, stock-based compensation administration, Board administration, patent portfolio administration and litigation matters. The Counsel employees providing the services are: 1) its Executive Vice President, Secretary and Chief Financial Officer, 2) its Senior Tax Manager, 3) an Accounting Manager, and 4) its Accounts Payable Clerk. These employees have the same or similar positions with CRBCI, but none of them receive compensation from CRBCI. Rather, Counsel allocates to CRBCI a percentage, based on time incurred, of the employees’ base compensation paid by Counsel. The amounts due under the Agreement are payable within 30 days following the respective year end, subject to applicable restrictions. Any unpaid fee amounts bear interest at 10% per annum commencing on the day after such year end.
