     1. Buyer has completed its financial due diligence, and the Initial Inspection Period is accordingly hereby amended to expire as of September 7, 2004. Buyer shall accordingly have no further right to terminate the Contract pursuant to Section 6.4(a) thereof, and $1,000,000 of the Xxxxxxx Money is accordingly now completely earned and non-refundable unless the Contract is terminated by Buyer in accordance with the terms of Section 6.3(b), Section 6.4(b) or Section 11.1 thereof.
