|4.01     Place and Time. The closing of the transaction contemplated by this Agreement ("Closing") shall occur when Seller is paid the Purchase Price. The Closing shall take place at the offices of Duane Morris, located at 633 West Fifth Street, Suite 4600, Los Angeles, California, at 10:00 a.m. local time, on or before August 18, 2006 ("Closing Date"). Said Closing Date shall, upon Buyer's written request, be extended for a period not to exceed thirty (30) calendar days by payment in advance to Seller of Five Thousand United States Dollars (US$5,000). Thereafter, the Closing Date shall be extended again for an additional period not to exceed thirty (30) calendar days, but not beyond October 15, 2006, by payment in advance to Seller of Seven Thousand Five Hundred United States Dollars (US$7,500), or if such additional period is less than thirty days, for a pro-rata portion of such amount. If the Buyer exercises one or both of the two options described in the preceding sentence, each of such payments is a payment, not a deposit, and is not refundable, and shall not be applied towards the Purchase Price.

An integral part of the understanding between the Parties and part of the consideration between the Parties for entering into this Agreement is that if this Agreement fails to close for any reason, including termination of this Agreement by either Party, or as a consequence of an alleged breach of any Party, neither Party shall recover from nor shall be allowed to seek to recover from the other Party any damages or alleged damages nor any Costs and Expenses of any type from the other Party and each Party affirmatively waives the right to seek from the other Party such damages or such Costs and Expenses.

|15.16    Non-Waiver and Other Miscellaneous Matters. No delay on the part of Seller or Buyer in the exercise of any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by Seller or Buyer of any right, power or remedy preclude other or further exercise thereof, or the exercise of any other right, power or remedy. No amendment, modification, or waiver or consent with respect to, any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed and delivered by Seller and Buyer, and then any such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. Consummation of the transaction contemplated herein shall not be deemed a waiver or a breach of any representation, warranty or covenant or of any Party's rights and remedies with regard thereto. No specific representation, warranty or covenant shall limit the generality or applicability of a more general representation, warranty or covenant. A breach of any representation, warranty or covenant shall not be affected by the fact that a more general representation, warranty or covenant was not also breached.
