     Rohm and Haas Company, a Delaware corporation (the “Company”), supplements and amends its Registration Statement on Form 8-A, dated October 26, 2000 (the “Registration Statement”), as follows:

Item 1. Description of Securities to be Registered.

     Reference is hereby made to the Preferred Stock Rights Agreement by and between the Company and Computershare Trust Company, N.A. (formerly known as EquiServe Trust Company, N.A.), as rights agent (the “Rights Agent”), dated as of October 26, 2000 (the “Rights Agreement”).

     On July 10, 2008, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, The Dow Chemical Company, a Delaware corporation (“Dow”), and Ramses Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Dow (“Merger Sub”), pursuant to which, upon the terms and subject to the conditions therein, Dow has agreed to acquire the Company. Also on July 10, 2008, in connection with the Merger Agreement, certain stockholders of the Company holding, in the aggregate, voting power of approximately 32% of the Company’s outstanding common stock have entered into a voting agreement (the “Voting Agreement”) with the Company and Dow pursuant to which such stockholders have agreed, among other things, to vote in favor of the adoption of the Merger Agreement.

     In contemplation of the execution of the Merger Agreement and the Voting Agreement, on July 9, 2008, the Company entered into a First Amendment (the “First Amendment”) to its Rights Agreement, dated as of October 26, 2000, between the Company and Computershare Trust Company, N.A. (formerly known as EquiServe Trust Company, N.A.) (the “Rights Agreement”), for the purpose of amending the Rights Agreement to render it inapplicable to the Merger Agreement, the Voting Agreement, the Merger and the other transactions contemplated thereby. In particular, the First Amendment provides that (1) no person will be deemed to be an Acquiring Person (as defined in the Rights Agreement) and no distribution of rights will occur solely by virtue of the approval, execution, delivery, adoption or performance of the Merger Agreement or the Voting Agreement or the consummation of the Merger or any other transactions contemplated thereby and (2) if they have not previously expired, the rights will expire immediately prior to the effective time of the Merger.

     The First Amendment is attached as Exhibit 4.2 hereto and is incorporated herein by reference.

Item 2. Exhibits.
