           Ribapharm Board Acknowledges Extension of ICN Tender Offer

COSTA MESA, Calif., July 31, 2003 - The Board of Directors of Ribapharm Inc.
(NYSE: RNA), acknowledged today the decision announced on July 30 by ICN
Pharmaceuticals, Inc. (NYSE: ICN) to extend the expiration date of its
unsolicited tender offer for shares of Ribapharm it does not already own to 5
p.m. (EDT) this Friday, August 1, 2003. In a press release issued on July 30,
and in related SEC filings, ICN also stated that stockholders "should not
expect" an increase in the tender offer price of $5.60 per share, and that ICN
"intends" to terminate the tender offer if an "adequate" number of shares are
not tendered by that time. On June 20, 2003, in the face of ICN's unsolicited
tender offer, the Ribapharm Board adopted a stockholder rights plan for the
purpose of preserving for Ribapharm's public stockholders Ribapharm's true
long-term value, determined that the ICN unsolicited tender offer was
inadequate, and recommended that Ribapharm's public stockholders not tender
their shares. This determination and recommendation were reaffirmed on July 20,
2003, the same date that the Board's financial advisor, Morgan Stanley & Co.
Incorporated, reiterated its opinion (subject to and based on the assumptions
and conditions set forth therein) that the $5.60 per share tender offer price
was inadequate from a financial point of view to holders of shares of Ribapharm
stock other than ICN and its affiliates.

In a statement issued today, Daniel J. Paracka, Chairman of the Board of
Ribapharm, said "The Board of Ribapharm continues to believe that the proposed
ICN tender offer price of $5.60 is inadequate, and continues to recommend that
stockholders not tender their shares at this price. The Board currently has no
plans to remove the stockholder rights plan. The Board remains willing to
negotiate with ICN for an increase in the tender offer price that adequately
reflects the value of Ribapharm. If the Board were to consider


                                      -1-



making the stockholder rights plan inoperative as to ICN's tender offer, it
would not do so without first providing our public stockholders with advance
notice, so that all of our public stockholders are given an opportunity to
consider the Board's decision before deciding whether or not to tender their
shares."

Where to Find More Information
------------------------------

In connection with ICN's unsolicited tender offer, Ribapharm has filed materials
with the Securities and Exchange Commission, including a Solicitation/
Recommendation Statement on Schedule 14D-9. STOCKHOLDERS ARE URGED TO READ THE

              RIBAPHARM INC. ANNOUNCES SECOND QUARTER 2003 RESULTS

                o Company reports net income of $0.17 per diluted share for the
                  quarter
                o Board reaffirms view on ICN tender offer
                o Research and development activities remain on track


      Costa Mesa, Calif., July 31, 2003 - Ribapharm Inc. (NYSE: RNA) today
announced second quarter 2003 net income of $25.8 million, or $0.17 per diluted
share, compared with $21.0 million or $0.14 per diluted share in the first
quarter 2003, a 22.9% increase, and $31.1 million or $0.21 per diluted share in
the second quarter 2002, a 17.1% decrease.

      Second quarter 2003 revenues were $52.0 million, up 7.0% compared with
$48.6 million in the first quarter 2003, and down 21.3% compared with $66.0
million in the second quarter 2002. All of Ribapharm's revenues were in the form
of royalty revenues derived from sales of ribavirin, a drug that Schering-Plough
Ltd. and F. Hoffmann-La Roche Ltd. currently market under license from
Ribapharm.

      The Company also announced today a favorable decision in the Company's
arbitration proceeding with Schering-Plough with respect to accrued royalties
relating to Schering-Plough's indigent patient marketing program. The
arbitration decision does not impact the Company's current income statements as
Ribapharm previously recognized a significant majority of the disputed amount as
income and recorded it as a receivable on its balance sheet.

      "Our financial results during the quarter were impacted by several
factors, including the effects of increasing competition between Schering-Plough
and F. Hoffmann-La Roche Ltd., who entered the market in January 2003," said Kim
D. Lamon, M.D., Ph.D., president and chief executive officer of Ribapharm.
"Royalty revenues in the second quarter 2003 also were negatively and materially
impacted by Schering-Plough's provision for estimated rebates on its U.S. sales
of ribavirin and changes in trade inventory levels, as reported to us by
Schering-Plough. We have no information with regard to the basis for the rebate
provision."

       Dr. Lamon added, "More importantly in terms of drivers of shareholder
value, our research and development on Viramidine(TM) and other products in our
pipeline have progressed well ahead of internal schedules. We have a September
3, 2003 meeting with the FDA to discuss preliminary Phase 2 data of Viramidine
and to discuss the potential of early commencement and design of Phase 3
clinical trials in the U.S. and Europe."

                                     - 1 -





      Dan Paracka, Chairman of the Board of the Company, said, "The Ribapharm
Board anticipated the second quarter 2003 results and such results were taken
into account in its analysis when it concluded that the ICN tender offer price
of $5.60 per share was inadequate, and consequently recommended that our public
stockholders not tender their shares to ICN at that price. Therefore, that
recommendation is unaffected by the results being announced."

       Operating income for the second quarter 2003 was $37.3 million, compared
with $33.5 million in first quarter 2003, an 11.3% increase, and $50.4 million
in the second quarter 2002, a decrease of 26.0%.

       Research and development expenses of $9.8 million in the second quarter
2003 increased 4.3% from $9.4 million in first quarter 2003, and decreased 28.5%
from $13.6 million in the second quarter 2002. The year over year decrease is
primarily attributable to the timing of costs associated with the clinical
trials of Viramidine(TM) and Hepavir B(TM). It is expected that costs will
increase during the second half of 2003 as progress continues with the clinical
trials of Viramidine and Hepavir B.

        General and administrative expenses were $4.9 million in the second
quarter 2003, compared with $5.6 million in the first quarter 2003 and $2.0
million in the second quarter 2002. General and administrative expenses were up
year over year primarily due to an increase of approximately $1.9 million in
legal costs incurred in the second quarter 2003 to defend patents against
generic pharmaceutical companies, to represent the Company and its Board of
Directors in connection with ICN's unsolicited tender offer and related
litigation, and to provide general business services. The remainder of the
increase is attributable to the existence of certain administrative departments
and public company costs, including Directors and Officers Insurance premiums,
that did not exist in the second quarter 2002 prior to the Company's initial
public offering in April 2002.

      The income tax rate decreased from 38% in the second quarter 2002 to 31.3%
in the second quarter 2003. The decrease is primarily attributable to an
adjustment in the second quarter 2003 to give effect to the decrease in the
Company's revised estimate of the 2003 annual effective tax rate from 37% to 34%
resulting from an expected increase in R&D tax credits.

      Net income for the six months ended June 30, 2003, was $46.8 million or
$0.31 per diluted share, compared with $61.1 million or $0.41 per diluted share
for the six months ended June 30, 2002, a 23.3% decrease. Royalty revenues for
the six months ended June 30, 2003 were $100.5 million, a decrease of $22.5
million or 18.3% from $123.0 million reported for the six months ended June 30,
2002.

      For the first six months of 2003, operating income was $70.8 million
compared to $98.7 million for the same period in 2002, a decrease of $27.9
million or 28.3%. Research and development expenses for the six months ended
June 30, 2003 were $19.2 million, down $1.0 million or 5.1% from $20.2 million
in 2002.

      General and administrative expenses for the six months ended June 30, 2003
and 2002 were $10.5 million and $4.1 million, respectively, for an increase of
$6.4 million. The increase is

                                     - 2 -





primarily attributable to a $4.1 million increase in legal costs to defend
patents against generic pharmaceutical companies, to represent the Company and
its Board of Directors in connection with ICN's unsolicited tender offer and
related litigation, and to provide general business services. The remainder of
the increase is attributable to the existence of certain of administrative
departments and public company costs that did not exist in 2002 prior to the
Company's initial public offering in April 2002.
