11.2                           Notices.  All notices, requests and other communications hereunder (herein collectively a “notice” or “notices”) shall be deemed to have been duly delivered, given or made to or upon any Party hereto if in writing and delivered by hand against receipt, or by certified or registered mail, postage pre-paid, return receipt requested, or to a courier who guarantees next business day delivery or sent by telecopy (with confirmation) to such Party at its address set forth below or to such other address as such Party may at any time, or from time to time, direct by notice given in accordance with this Section 11.2.
