NOW, THEREFORE, for and in consideration of the mutual benefits and obligations of the parties herein stated, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties, the Licensee, the Licensor and the Bank hereby agree as follows: 1. Account. The Bank has established a segregated interest-bearing account ------- in Australia in the name of the Licensor, account number BSB036000 Account Number 398957 (the "Account"). The Bank acknowledges that the Licensee may from time to time remit funds to the Bank for deposit into the Account; and in such case, the Bank shall deposit such funds into the Account and maintain such funds in the Account, solely on the terms and conditions of this Agreement. 2. Release and Delivery of Funds. The Bank shall release and transfer any funds on deposit in, or credited to, the Account as follows: (a) Promptly upon the Bank's receipt of a written notice from the Licensee and the Licensor substantially in the form of the attached Exhibit A, that appears on its face to be genuine, the Bank will comply with the instructions to transfer the amount specified in such notice to the order of the Licensor (to the account specified in such notice). (b) Promptly upon the Bank's receipt of a written notice from the Licensee substantially in the form of the attached Exhibit B, that appears on its face to be genuine, the Bank will comply with the instructions to transfer the amount specified in such notice to the order of the Licensee (to the account specified in such notice). (c) The Bank agrees not to permit any funds on deposit or credited to the Account to be transferred to any person or entity other than (i) as expressly set forth in clauses (a) and (b) of this Section 2 or (ii) upon express written instructions jointly signed by the Licensee and the Licensor and containing a representation by each of the Licensee and the Licensor that the person signing the same is authorized to do so in accordance with the terms of this Agreement. The Licensor and the Licensee hereby agree that in the event that the Licensor is liquidated as a result of an involuntary proceeding brought against it under any applicable bankruptcy, insolvency, reorganization or other similar law, the Licensee shall be entitled to all amounts then on deposit in the Account. (d) The Licensee agrees not to provide to the Bank any notice contemplated by Exhibit B prior to 5:00 p.m. United States Central Standard Time on 31 August 2004. In the event that the Bank nevertheless receives any notice contemplated by Exhibit B prior to September 1, 2004, the Bank shall not withdraw or transfer funds or take any action on the basis of any such notice. 3. Interest. Credit balances in the Account shall bear interest, which will -------- be calculated daily and paid monthly to the Account. Interest will be set at the weekly average 30-day Bank Bill Offer Rate less 75 basis points (0.75% p.a.), resulting in a current rate of approximately 5.36% p.a. (as at 13 July 2000). The 30-Day Bank Bill Offer Rate is published each day in the Australian Financial Review newspaper and can be monitored via Reuters BBSY screen. This rate is published daily and the average weekly rate can be calculated internally from the published rate. Interest earned on funds that are on deposit in or credited to the Account shall, in all events be deemed earned by the Licensor and shall be added to the funds on deposit in the Account or paid to the Licensor upon request by the Licensor; provided, however, that if the Bank at any time receives a written notice from the Licensee substantially in the form of the attached Exhibit C that appears on its face to be genuine (the "Major Default Notice"), then the Licensor shall not be entitled to receive any amount of interest accrued from the date specified in the Major Default Notice and the Bank shall not pay such amount of interest to the Licensor until such time as the Bank receives from the Licensee a written notice substantially in the form of the attached Exhibit D that appears on its face to be genuine. 4. Extent of Bank's Responsibilities. The Bank's liabilities and obligations are limited to those specifically set forth in this Agreement. The Bank shall not be liable for any act or omission by it in good faith in connection with this Agreement, provided, however, that the Bank shall be liable for any negligence or willful misconduct on its part. 5. No Set-off. The Bank agrees that it will not obtain (by agreement, operation of law or otherwise) a lien on or other charge over the Account or any funds on deposit in or credited to the Account; and that such funds will not be subject to deduction, set-off, banker's lien, or any other right in favor of any person or entity other than the Licensor or the Licensee, provided that the Bank may set off amounts due to it in respect of fees and expenses customarily charged for its performance of the services described in this Agreement only against accrued interest. 6. Expenses of Bank. All taxes (other than taxes on its overall net income) costs and expenses incurred by Bank in carrying out the Bank's obligations under this Agreement or in opening, operating, or closing the Account shall be paid or reimbursed by the Licensor as incurred and the Bank may debit those costs and expenses to the Account (but only against accrued interest) when they are incurred. 7. Indemnification of Bank. The Licensor hereby agrees to indemnify, defend and hold harmless Bank for all losses, costs and expenses (including reasonable attorneys' fees) suffered or incurred by Bank and arising out of documents entered into by the Bank, or matters, things and activities (acts and omissions) of the Bank under this Agreement, provided that such activities were performed by the Bank in good faith and without any negligence or willful misconduct on the part of the Bank.
