II. OBJECTIVES

The proposed Final Judgment filed in this case is meant to ensure Cemex's prompt divestiture of the Divestiture Assets, for the purpose of maintaining competition in the production and distribution of ready mix concrete in certain areas of Florida and Arizona; of concrete block in the areas of Tampa, Fort Myers, and Naples, Florida; and of aggregate in the area of Tucson, Arizona, to remedy the effects that the United States alleges would otherwise result from Cemex's acquisition of Rinker. This Amended Hold Separate Stipulation and Order ensures that, prior to such divestitures, the Divestiture Assets remain independent, economically viable, and ongoing business concerns that will remain independent and uninfluenced by Cemex's acquisition of Rinker, and that competition is maintained during the pendency of the ordered divestitures.

III. JURISDICTION AND VENUE

This Court has jurisdiction over the subject matter of plaintiff's Amended Complaint alleging that the proposed acquisition of Rinker by Cemex would violate Section 7 of the Clayton Act (15 U.S.C. § 18), 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 proposed 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15 U.S.C. § 16, and without further notice to any party or other proceedings, provided that the United States has not withdrawn its consent, which it may do at any time before the entry of the proposed Final Judgment by serving notice thereof on defendants and by filing that notice with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. Cemex 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 Amended 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 Amended Complaint herein before the Court has signed this Amended Hold Separate Stipulation and Order.

D. This Amended Hold Separate Stipulation and Order shall apply with equal force and effect to any subsequent 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); or (2) the proposed Final Judgment is not entered pursuant to this Amended 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 Amended Hold Separate Stipulation and Order, and the making of this Amended Hold Separate Stipulation and Order shall be without prejudice to any party in this or any other proceeding.

F. Cemex represents that the divestitures ordered in the proposed Final Judgment can and will be made, and that Cemex 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 divestitures required by the proposed Final Judgment have been accomplished:

A. Each defendant shall preserve, maintain, and continue to operate those Divestiture Assets owned by that defendant prior to an acquisition of Rinker as ongoing, economically viable competitive businesses. In addition, from the date of the Divestiture Trigger, Cemex shall preserve, maintain, and continue to operate those Divestiture Assets owned by Rinker prior to an acquisition by Cemex as ongoing, economically viable competitive businesses. Each defendant shall maintain the management, sales, and operations of all assets owned by that defendant prior to an acquisition of Rinker entirely separate, distinct, and apart from the assets owned by the other defendant prior to an acquisition by Cemex. Neither defendant shall coordinate the production, marketing, or terms of sale of any of its products with those produced by or sold under any assets owned by the other defendant prior to an acquisition by Cemex. Within twenty (20) days after the entry of this Amended Hold Separate Stipulation and Order, defendants will inform the United States of the steps defendants have taken to comply with this Amended Hold Separate Stipulation and Order.

B. Defendants shall take all steps necessary to ensure that: (1) the Divestiture Assets will be maintained and operated as ongoing, economically viable and active competitors in the ready mix concrete, concrete block, and aggregate businesses; (2) management of the Divestiture Assets owned by Rinker prior to an acquisition by Cemex will not be influenced by Cemex; and (3) the books, records, competitively sensitive sales, marketing, and pricing information, and decision-making concerning production and distribution of products by or under any assets owned by Cemex prior to an acquisition of Rinker will be kept separate and apart from the assets owned by Rinker prior to an acquisition by Cemex.

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 Assets, and shall maintain at 2007 or previously approved levels for 2008, whichever are higher, all promotional, advertising, sales, technical assistance, marketing, and merchandising support for the Divestiture Assets.

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

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

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 of the Divestiture Assets.

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 Assets.

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

I. Defendants' employees involved in production, operations, and sales at the Divestiture Assets 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 take no action that would interfere with the ability of any trustee appointed pursuant to the proposed Final Judgment to complete the divestitures pursuant to the proposed Final Judgment to an Acquirer or Acquirers acceptable to the United States.

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