      This Amendment No. 9 amends and supplements the Schedule 14D-9 filed with
the Securities and Exchange Commission (the "SEC") on June 23, 2003 and as
subsequently amended (the "Schedule 14D-9") by Ribapharm Inc., a Delaware
corporation ("Ribapharm" or the "Company"), relating to the tender offer by Rx
Acquisition Corporation, a Delaware corporation ("Purchaser"), and a
wholly-owned subsidiary of ICN Pharmaceuticals, Inc., a Delaware corporation
("ICN"), to purchase all of the outstanding shares of Ribapharm's common stock,
par value $.01 per share, which are not currently owned by ICN and its
subsidiaries (the "Publicly Held Shares"), at a purchase price of $5.60 per
share (the "Offer Price"), net to the seller in cash, without interest thereon,
upon the terms and subject to the conditions set forth in Purchaser's Offer to
Purchase, dated June 10, 2003 (the "Offer to Purchase"), and in the related
Letter of Transmittal (which together with the Offer to Purchase and any
amendments or supplements thereto collectively constitute the "Offer"). The
Offer is disclosed on a Tender Offer Statement and Rule 13e-3 Transaction
Statement filed under cover of Schedule TO with the SEC on June 10, 2003 by ICN
and as subsequently amended (the "Schedule TO"). Capitalized terms used herein
and not otherwise defined have the meanings ascribed to them in the Schedule

Item 4.         The Solicitation or Recommendation.

     The subsection entitled "Background of the Transaction" of Item 4 is hereby
amended and supplemented by adding the following paragraph at the end thereof:

     On July 31, 2003, the Company held its earnings conference call to announce
its second quarter financial results. During that call, Daniel Paracka, the
Chairman of the Ribapharm Board, stated that the Ribapharm Board anticipated
these second quarter results and that such results were taken into consideration
in the Ribapharm Board's analysis of the Offer and conclusion that the Offer was
inadequate. Mr. Paracka continued by stating that the Ribapharm Board's
recommendation to reject the Offer is therefore unaffected by the results
announced on the conference call. He also said that the Ribapharm Board is fully
committed to ensuring that Ribapharm's Public Stockholders are treated fairly,
are not rushed into making important judgments and are fully informed with
respect to both the terms of the Offer and the Ribapharm Board's views
concerning the Offer. Kim Lamon, the Company's President and Chief Executive
Officer, added that the management of Ribapharm is fully in agreement with and
supportive of the position taken by the Ribapharm Board.


      After due inquiry and to the best of my knowledge and belief, I certify
that the information set forth in this statement is true, complete and correct.

                                    RIBAPHARM INC.
