 absolute discretion not to deliver Precious Metal if it so decides.2.         Except

 (H&H) Noon Price in the case of AMI and the London Fixing Price with
 respect to the European Consignees; (b) with respect to each of gold,
 platinum and palladium, the daily London Afternoon Fixing Price for such
 metal; and (c) with
 respect to rhodium, a price based on an index determined by Scotiabank at the
 time of the making of any particular consignment (Rhodium Index Price); in
 each case, on such day times the number of ounces of silver, gold,
 platinum, palladium or rhodium, as applicable, in respect of which the Dollar
 Value is being determined. In the event that there is no H&H Noon Price

 troy ounces of silver; and (ii) Two Hundred Seven Million U.S. Dollars
 ($207,000,000 U.S.) (such $207,000,000 U.S. being the Maximum Dollar
 Limit).5.         Paragraph
 2 of the Consignment Agreement is amended hereby in its entirety to read as
 follows:2.          Restoration

 telecopied notice to the Consignees, require that by the end of the Business
 Day immediately following the day upon which such telex or telecopied notice
 is given, the Consignees either:(i)          Re-deliver

 to reduce the Dollar Value of the Precious Metal continued to be held on
 consignment hereunder to an amount no greater than the Maximum Dollar Limit;

 from Scotiabank, at the applicable price used to determine the Dollar Value
 hereunder, plus any applicable premium (as provided in Paragraph 14

 Consignment hereunder to an amount no greater than the Maximum Dollar Limit.May 8, 2008

 mutually agreed to in advance of delivery. Rhodium delivered to the
 Consignees and returned to Scotiabank shall be in granular form and of a
 minimum fineness of .999, unless otherwise mutually agreed to in advance of

 EXPRESS OR IMPLIED, WITH RESPECT TO THE PRECIOUS METAL CONSIGNED OR TO BE
 CONSIGNED OR SOLD HEREUNDER, WHETHER AS TO MERCHANTABILITY, FITNESS FOR A

 SUCH WARRANTIES.7.         Paragraph
 9 of the Consignment Agreement is amended hereby in its entirety to read as
 follows:9.          Safekeeping.
 Until such time as the Precious Metal received from Scotiabank has been
 returned to Scotiabank or purchased by the Consignees, as hereinafter
 provided, the Consignees will afford the Precious Metal no less safekeeping

 authorized representative of the applicable Consignee at least two (2)
 Business Days (or such lesser period as Scotiabank may accommodate) prior to
 the proposed value date with a quotation (based upon the applicable price
 used to determine the Dollar Value hereunder, plus any applicable premium) of
 the value date price of the Precious Metal to be purchased. If the authorized
 representative of the applicable Consignee agrees to such quotation, such
 quantity of Precious Metal will thereupon be conclusively deemed to have been
 contracted for purchase, with payment of the purchase price to be made on the
 agreed upon value date.9.         Paragraph
 12 of the Consignment Agreement is amended hereby in its entirety to read as
 follows:12.          Security.

 hereunder; and (b) each of the Consignees hereby grants to Scotiabank a lien
 on and a security interest in all of each Consignees right, and interest in
 the consigned Precious Metal, the products, and the proceeds thereof. Each of
 the Consignees agrees that Scotiabank may file financing statements (or
 similar instruments under applicable law) evidencing the foregoing security
 interest in any jurisdiction where any consigned Precious Metal is located or

 provide notice of any transactions.May 8, 2008

 financing statement (or similar instrument) filed in accordance with this
 paragraph shall describe the covered property as follows (provided, however, in jurisdictions in which the Uniform Commercial Code is not

 be necessary to properly evidence the foregoing security interest under the
 laws of such jurisdiction):Any and all silver, gold, platinum, palladium and
 rhodium in all forms and of every kind, nature and description consigned or
 to be consigned by The Bank of Nova Scotia to AMI Doduco, Inc., AMI Doduco

 follows:14.          Payments.
 Payment of the consignment fee will be made by the applicable Consignee
 within ten (10) Business Days following the 22nd day of each month and on the
 last day of a Consignment term. Payment of the purchase price of silver will
 be made on the value date and shall be determined by the H&H Noon Price
 and/or the London Fixing Price, as the case may be, with respect to silver on
 such day plus a premium of $0.015 per ounce times the number of ounces of

 17(g) and Subparagraph 17(h) of the Consignment Agreement are amended hereby
 in their entirety to read as follows:(g)          any
 of the Consignees or the Guarantor admits its inability to pay its debts

 claims the Guarantee to be invalid or withdrawn in whole or in part; or the
 Guarantee is determined to be invalid in whole or in part by a court or other
 judicial entity, or is invalidated in whole or in part by any act, regulation
 or governmental action and the Guarantor fails to provide Scotiabank with a

 the Guarantor, the Consignee and certain other subsidiaries of the Guarantor,
 JPMorgan Chase Bank, N.A. as Administrative Agent, Swing Line Lender and L/C
 Issuer and the Lenders (all as defined in the Credit Agreement), as the same

 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

 including, without limitation, pursuant to that certain Consignment and/or

 final paragraph of Paragraph 17 of the Consignment Agreement is amended
 hereby in its entirety to read as follows:Scotiabank may terminate this Agreement and, upon

 the Consignees deliver to Scotiabank forthwith all Precious Metal held by the
 Consignees on consignment for Scotiabank hereunder and shall be entitled to
 receive payment forthwith from the Consignees 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 Consignees
 as of the date and time of termination and by so paying such amount, the
 Consignees shall be deemed to have purchased the Precious Metal that they
 were required to re-deliver to Scotiabank. If the Consignees fail 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.14.       Except
