1. Defined Terms. Initially capitalized terms used but not defined in this Amendment have the meanings given to such terms in the Consignment Agreement.

2. Amendments.

(a) The definition of “Maturity Date” appearing in Section 1 of the Consignment Agreement is hereby amended and restated in its entirety to read as follows:

“Maturity Date” means September 30, 2013. Any obligations of the Customers under this Agreement that are not paid when due on or before the Maturity Date shall remain subject to the provisions of this Agreement until all Obligations are paid and performed in full.

Section 2.6 Inability to Determine Fixed Consignment Fee.

In the event, prior to the commencement of any Fixed Rate Period relating to any Fixed Rate Consignment, the applicable Metal Lender shall determine in good faith that adequate and reasonable methods do not exist for ascertaining the Fixed Consignment Fee that would otherwise determine the Fixed Rate Consignment during any Fixed Rate Period, the applicable Metal Lender shall forthwith give notice of such determination (which shall be conclusive and binding on the Customer) to the Customer. In such event, (a) any request for a Fixed Rate Consignment shall be automatically withdrawn and shall be deemed a request for a Floating Rate Consignment; (b) each Fixed Rate Consignment will automatically on the last day of the then current Fixed Rate Period thereof, become a Floating Rate Consignment; and (c) the obligations of the applicable Metal Lender to make Fixed Rate Consignments shall be suspended until the circumstances giving rise to such suspension no longer exist, whereupon the applicable Metal Lender shall so notify the Customers.

(c) concurrently with any delivery of financial statements under Section 9.1(a) or 9.1(b) above, a certificate of an executive officer of Materion (i) showing the calculations necessary to determine compliance with this Agreement, and (ii) certifying as to whether a Default has occurred and, if a Default has occurred, specifying the details thereof and any action taken or proposed to be taken with respect thereto;

(d) Section 9.3 of the Consignment Agreement is hereby amended and restated in its entirety to read as follows:

Section 9.3 Notices.

Each Customer through the Customer Agent, will give prompt notice in writing to the Metal Lenders of: (a) the occurrence of any Default; (b) the filing or commencement of any action, suit or proceeding by or before any arbitrator or governmental authority against or affecting any Customer that, if adversely determined, could reasonably be expected to result in a Material Adverse Effect; (c) any Lien (other than Permitted Metal Liens) attaching or asserted against any material portion of the Collateral; (d) any loss, damage, or destruction to the Collateral in the amount of $500,000 or more, whether or not covered by insurance; (e) the occurrence of any “Default” under the Senior Credit Agreement or any “Event of Default” under any Permitted Metals Agreement which is subject to the Metal Intercreditor Agreement; (f) the occurrence of any “Default” or “Event of Default” under any other Permitted Metal Agreement not described in the preceding clause (e) which has resulted in the exercise or commencement of any creditor remedies thereunder against Metal in the possession, custody or control of any Customer; (g) any other development that results in, or could reasonably be expected to result in, a Material Adverse Effect; and (h) any amendment, supplement or restatement of the Senior Credit Agreement, together with a copy thereof. Each notice delivered under this Section 9.3 shall be accompanied by a statement of an executive officer of BEM setting forth the details of the event or development requiring such notice and any action taken or proposed to be taken with respect thereto.
