1. Foseco's Saybrook, Ohio facility, and the related leasehold;

II. OBJECTIVES

The proposed Final Judgment filed in this case is meant to ensure defendants' prompt divestiture of the Divestiture Business for the purpose of maintaining competition in the manufacture and sale of CBCs in the United States in order to remedy the effects that the United States alleges would otherwise result from Cookson's acquisition of Foseco. This Hold Separate Stipulation and Order ensures that, prior to such divestiture, the Divestiture Business remains an independent, economically viable, and ongoing business concern that will remain independent and uninfluenced by Cookson's acquisition of Foseco, and that competition is maintained during the pendency of the ordered divestiture.

III. JURISDICTION AND VENUE

This Court has jurisdiction over the subject matter of this action and defendants do not object either to the Court's exercise of personal jurisdiction in this case or to the propriety of venue of this action in the United States District Court for the District of Columbia.

IV. COMPLIANCE WITH AND ENTRY OF FINAL JUDGMENT

A. The parties stipulate that a Final Judgment in the form attached hereto as Exhibit A may be filed with and entered by the Court, upon the motion of any party or upon the Court's own motion, at any time after compliance with the requirements of the Antitrust Procedures and Penalties Act ("APPA"), 15 U.S.C. § 16, and without further notice to any party or other proceedings, provided that the United States has not withdrawn its consent, which it may do at any time before the entry of the proposed Final Judgment by serving notice thereof on defendants and by filing that notice with the Court.

B. Defendants shall abide by and comply with the provisions of the proposed Final Judgment, pending the Judgment's entry by the Court, or until expiration of time for all appeals of any Court ruling declining entry of the proposed Final Judgment, and shall, from the date of the signing of this Hold Separate Stipulation and Order by the parties, comply with all the terms and provisions of the proposed Final Judgment as though the same were in full force and effect as an Order of the Court.

C. Defendants shall not consummate the transaction sought to be enjoined by the Complaint herein before the Court has signed this Hold Separate Stipulation and Order.

D. This Hold Separate Stipulation and Order shall apply with equal force and effect to any amended proposed Final Judgment agreed upon in writing by the parties and submitted to the Court.

E. In the event: (1) the United States has withdrawn its consent, as provided in Paragraph IV(A) above; or (2) the proposed Final Judgment is not entered pursuant to this Hold Separate Stipulation and Order, the time has expired for all appeals of any Court ruling declining entry of the proposed Final Judgment, and the Court has not otherwise ordered continued compliance with the terms and provisions of the proposed Final Judgment, then the parties are released from all further obligations under this Hold Separate Stipulation and Order, and the making of this Hold Separate Stipulation and Order shall be without prejudice to any party in this or any other proceeding.

F. Defendants represent that the divestiture ordered in the proposed Final Judgment can and will be made and that defendants later will raise no claim of mistake, hardship, or difficulty of compliance as grounds for asking the Court to modify any of the provisions contained therein.

V. HOLD SEPARATE PROVISIONS

Until the divestiture required by the Final Judgment has been accomplished:

A. Defendants shall preserve, maintain, and continue to operate the Divestiture Business as an independent, ongoing, economically viable competitive business, with management, sales, and operations of such assets held entirely separate, distinct, and apart from those of defendants' other operations. Defendants shall not coordinate their production, marketing, or terms of sale of any products with those produced by or sold under the Divestiture Business. Within twenty (20) days after the entry of this Hold Separate Stipulation and Order, defendants will inform the United States of the steps defendants have taken to comply with this Hold Separate Stipulation and Order.

B. Defendants shall take all steps necessary to ensure that: (1) the Divestiture Business will be maintained and operated as an independent, ongoing, economically viable, and active competitor in the CBC business; (2) management of the Divestiture Business will not be influenced by defendants; and (3) the books, records, competitively sensitive sales, marketing, and pricing information, and decision-making concerning the production, distribution, and sale of products produced by or sold under the Divestiture Business will be kept separate and apart from defendants' other operations.

C. Defendants shall use all reasonable efforts to maintain and increase the sales and revenues of the products produced by or sold under the Divestiture Business, and shall maintain at 2008 or previously approved levels for 2009, whichever are higher, all promotional, advertising, sales, technical assistance, marketing, and merchandising support for the Divestiture Business.

D. Defendants shall provide sufficient working capital and lines and sources of credit to continue to maintain the Divestiture Business as an economically viable and competitive, ongoing business, consistent with the requirements of Paragraphs V(A) and (B).

E. Defendants shall take all steps necessary to ensure that the Divestiture Business is fully maintained in operable condition at no less than current capacity and sales and shall maintain and adhere to normal repair and maintenance schedules for the Divestiture Business.

F. Defendants shall not, except as part of a divestiture approved by the United States in accordance with the terms of the proposed Final Judgment, remove, sell, lease, assign, transfer, pledge, or otherwise dispose of any asset or assets of the Divestiture Business.

G. Defendants shall maintain, in accordance with sound accounting principles, separate, accurate, and complete financial ledgers, books, and records that report on a periodic basis, such as the last business day of every month, consistent with past practices, the assets, liabilities, expenses, revenues, and income of the Divestiture Business.

H. Defendants shall take no action that would jeopardize, delay, or impede the sale of the Divestiture Business.

I. Defendants' employees with primary responsibility for the production, operation, and sale of CBCs for the Divestiture Business, shall not be transferred or reassigned to other areas within the company except for transfer bids initiated by employees pursuant to defendants' regular, established job posting policy. Defendants shall provide the United States with ten (10) calendar days notice of such transfer.

J. Defendants shall appoint a person or persons, subject to the approval of the United States in its sole discretion, to oversee the Divestiture Business, and who will be responsible for defendants' compliance with this Section. This person shall have complete managerial responsibility for the Divestiture Business, subject to the provisions of the proposed Final Judgment. In the event such person is unable to perform his duties, defendants shall appoint, subject to the approval of the United States in its sole discretion, a replacement within ten (10) working days. Should defendants fail to appoint a replacement acceptable to the United States within this time period, the United States shall appoint a replacement.

K. Defendants shall take no action that would interfere with the ability of any trustee appointed pursuant to the Final Judgment to complete the divestiture pursuant to the Final Judgment to an Acquirer acceptable to the United States.

L. This Hold Separate Stipulation and Order shall remain in effect until: (1) the consummation of the divestiture required by the proposed Final Judgment; (2) further order of the Court; or (3) the United States' voluntary dismissal of the Complaint in this matter.
