 Administrative Agent to declare any or all of the obligations under the
 Credit Agreement to be immediately due and payable. Such Credit Agreement
 Events of Default (together with related definitions and ancillary
 provisions) shall, for as long as this Agreement has not been terminated and
 is in full force and effect, be a part of and are hereby incorporated into
 this Agreement by reference, mutatis mutandis, as if such Events of Default
 were set forth in this Agreement in full, without regard to any termination
 of such Credit Agreement. Insofar as any provisions of the Credit Agreements
 Events of Default conflict with or are inconsistent with any provisions of the
 Events of Default of this Agreement, then the provisions of this Agreement
 shall govern to the extent of the conflict or inconsistency, provided that
 the non-inclusion of a provision in either document shall not constitute a
 conflict or inconsistency for the purposes of this provision;(k)          default

 become entitled to have the Consignee deliver to Scotiabank forthwith all
 Precious Metal held by the Consignee on consignment for Scotiabank hereunder
 and shall be entitled to receive payment forthwith from the Consignee of all
 amounts due and accruing to Scotiabank hereunder. Delivery of such Precious
 Metal shall be made by either physically delivering the Precious Metal to
 Scotiabank or by paying to Scotiabank the applicable price used to determine
 the Dollar Value hereunder, plus the applicable premium of the Precious Metal
 then held by the Consignee as of the date and time of termination and by so
 paying such amount, the Consignee shall be deemed to have purchased the
 Precious Metal that they were required to re-deliver to Scotiabank. If the
 Consignee fails to immediately deliver to Scotiabank all such Precious Metal
 held on consignment hereunder or fail to immediately pay to Scotiabank all
 other amounts due to it hereunder, Scotiabank may proceed to take such steps
 as it deems fit, including realizing upon any security it holds in that
 respect.13.       Except

 obligations under the Facility Documents.May 8, 2008
