                RIBAPHARM SEEKS ICN'S BOARD ASSURANCE OF SPIN-OFF

COSTA MESA, Calif., December 20, 2002 - Ribapharm Inc. (NYSE: RNA) today
announced that it has requested assurances from ICN Pharmaceuticals, Inc.
("ICN"), its 80% shareholder, that ICN intends to proceed with its previously
announced tax free spin off to ICN shareholders of all of its shares of
Ribapharm common stock.

In a letter to ICN, Ribapharm requested a resolution from ICN's Board of
Directors certifying ICN's intention to complete the spin off. Ribapharm noted
in the letter that it had entered into certain tax arrangements under a tax
sharing agreement with ICN based on the previously announced spin off. In
connection with the continued performance of Ribapharm's obligations under that
agreement, Ribapharm stated that it would need assurances of ICN's previously
announced intentions.

"ICN committed publicly to spin off Ribapharm, and on behalf of all our
stockholders we need to determine if ICN has now changed its position," said
Johnson Y.N. Lau, M.D., Chairman and CEO of Ribapharm. "The Ribapharm Board of
Directors is committed to enhancing the value of Ribapharm for all our
stockholders, and continues to believe that the spin off is in the best
interests of both ICN and Ribapharm."

Ribapharm is a biopharmaceutical company that seeks to discover, develop,
acquire and commercialize innovative products for the treatment of significant
unmet medical needs, principally in the antiviral and anticancer areas.

   AMENDMENT TO BYLAWS ADOPTED BY THE BOARD OF DIRECTORS ON DECEMBER 13, 2002

         RESOLVED, that the Bylaws of the Company be amended by adding a new
Section 8(C)(4) to Article I in the form set forth in the attachment to these
minutes, and the executive officers of the Company are hereby authorized to
prepare any filings with the Securities and Exchange Commission, the New York
Stock Exchange or other applicable authority to give notice of such Bylaw
amendment.

                 NEW SECTION 8(C)(4) OF ARTICLE I OF THE BYLAWS

(4)      The advance notice of the proposal of business by stockholders required
         by Article VI, Section (c) of the Certificate of Incorporation shall be
         given in the manner set forth in this Section 8. In the case of action
         to be taken by stockholders at any annual or special meeting of
         stockholders, the required notices are set forth in paragraphs (A) and
         (B) of this Section 8. In the case of action to be taken by
         stockholders by written consent (during the period when action by

         Certificate of Incorporation), the stockholder or stockholders
         proposing to take such action shall give notice of the proposed action,
         which notice shall be in writing and delivered to the Secretary at the
         principal executive offices of the Corporation, a reasonable period
         (but not less than 35 days) before the proposed effective date of such
         action. Without limiting the foregoing, and consistent with paragraph
         (C)(3) of this Section 8, it is the intent of this notice requirement
         that the Corporation will be allowed an appropriate period to comply
         with Rule 14c-2 under the Exchange Act and other applicable disclosure
         requirements. To the extent relevant, the notice shall include the
         information referred to in paragraph (A)(2) of this Section 8.
