3.4. ABANDONMENT OF THE DISTRIBUTION. The parties expressly acknowledge and
agree that ICN is not obligated in any respect to proceed with or complete the
Distribution and that ICN may, in its sole and absolute discretion, at any time
abandon its plans to proceed with or complete the Distribution. In the event
that ICN so determines that it no longer intends to proceed with or complete the
Distribution, ICN shall provide to Ribapharm a written notification of such
determination (an "Abandonment Notice"). Effective as of the date of the
Abandonment Notice, (a) provided that no Distribution Date has yet occurred,
Section 3.3, 5.2 and 5.3 of this Agreement shall terminate, become null and void
and have no further force and effect (it being expressly understood and agreed
by the parties that such sections shall remain in full force and effect in the
event that a Distribution Date has occurred on or prior to the date of the
Abandonment Notice) and (b) ICN's rights, and Ribapharm's obligations, set forth
in the Registration Rights Agreement shall immediately become effective.

4. EXPENSES AND PRIOR RELATIONSHIP.

4.1. EXPENSES GENERALLY. Except as otherwise provided in this Agreement, all
costs and expenses of either party hereto in connection with this Agreement
shall be paid by the party that incurs such costs and expenses.

4.2. CERTAIN EXPENSES RELATING TO THE INITIAL PUBLIC OFFERING. ICN shall be
liable for all costs, fees and expenses relating to the Initial Public Offering,
including the costs and expenses of financial, legal, accounting and other
advisers.

costs, fees and expenses relating to the Distribution; provided that Ribapharm

of Ribapharm's financial, legal, accounting and other advisors incurred in
connection with the Distribution if such financial, legal, accounting and other
advisors are not concurrently engaged by ICN and (b) any internal fees, costs
and expenses incurred by Ribapharm or any Ribapharm Affiliate in connection with
the Distribution.

4.4 PRIOR RELATIONSHIP. Ribapharm, with respect to Ribapharm and all of the
Ribapharm Affiliates, and ICN, with respect to ICN and all of the ICN
Affiliates, agree to take all commercially reasonable action to discontinue
their respective uses as promptly as is commercially reasonable of any printed
material that indicates an ownership or other relationship between or among ICN
and Ribapharm or any of their respective Affiliates that has changed as a result
of the Initial Public Offering, the Distribution or any other transactions
contemplated hereby; provided that this Section 4.4 shall not prohibit the use
of printed material containing appropriate and accurate references to such

5.       ADDITIONAL COVENANTS.

         5.1. FINANCIAL STATEMENTS COVENANTS. For so long as ICN is required to
include in its consolidated financial statements Ribapharm's results of
operations (determined in accordance with GAAP):

                  (i) Ribapharm shall, and shall cause each Ribapharm Affiliate
to, maintain a fiscal year which commences on January 1 and ends on December 31
of each calendar year.

                  (ii) Ribapharm shall deliver to ICN all schedules consistent
with ICN's corporate closing requirements and in a time consistent with ICN's
corporate closing schedule.

                  (iii) Except to the extent required by law (including SEC
rules and regulations), Ribapharm shall cause PricewaterhouseCoopers, LLP
("PwC") to be retained as the independent certified public accountants to audit
its consolidated financial statements ("Ribapharm's Auditors") unless (x)
Ribapharm receives the prior written consent of ICN (which consent will not be
unreasonably withheld if Ribapharm has demonstrated to ICN that it is justified
in not retaining PwC by reason of any action or inaction of PwC), (y) ICN no
longer uses PwC to audit its consolidated financial statements or (z) PwC
resigns as Ribapharm's Auditors. If PwC ceases to be Ribapharm's Auditors, then
Ribapharm shall retain independent certified public accountants of nationally
recognized standing as Ribapharm's Auditors.

                  (iv) As soon as practicable, and in any event within 35 days
after the end of each of the first three fiscal quarters in each fiscal year of
Ribapharm (but in no event later than five days before Ribapharm intends to file
its Quarterly Financial Statements (as defined below) with the SEC), Ribapharm
shall deliver to ICN drafts of (A) the consolidated financial statements of
Ribapharm (and notes thereto) for such periods and for the period from the
beginning of the current fiscal year to the end of such quarter, setting forth
in each case in comparative form for each such fiscal quarter of Ribapharm the
consolidated figures (and notes thereto) for the corresponding quarter and
periods of the previous fiscal year and all in reasonable detail and prepared in
accordance with Regulation S-X, and (B) a discussion and analysis by management
of Ribapharm's consolidated financial condition and results of operations for
such fiscal period, including, without limitation, an explanation of any
material adverse change from the immediately preceding fiscal quarter, all in
reasonable detail and prepared in accordance with Item 303(b) of Regulation S-K.
The information set forth in (A) and (B) above is herein referred to as the
"Quarterly Financial Statements." No later than the earlier of (x) two Business
Days prior to the date Ribapharm files its Quarterly Report on Form 10-Q with
the SEC or otherwise makes its Quarterly Financial Statements publicly available
or (y) two Business Days prior to the date on which ICN has notified Ribapharm
that it intends to file its Quarterly Report on Form 10-Q with the SEC (but in
no event earlier than the 5th day before ICN's Quarterly Report on Form 10-Q is
required to be filed with the SEC), Ribapharm shall deliver to ICN the final
form of the Quarterly Financial Statements certified by the chief financial
officer of Ribapharm as presenting fairly, in all material respects, the
consolidated financial condition and results of operations of Ribapharm;
provided that ICN and Ribapharm financial representatives shall actively consult
with each other regarding any changes (whether or not substantive) which
Ribapharm may

                                      -12-
<PAGE>   14
consider making to its Quarterly Financial Statements and related disclosures
prior to the actual filing of its Quarterly Report on Form 10-Q with the SEC.

                  (v) Ribapharm shall use its reasonable best efforts to enable
Ribapharm's Auditors to complete their audit such that they will date their
opinion on Ribapharm's audited annual financial statements on the same date that
ICN's independent certified public accountants ("ICN's Auditors") date their
opinion on ICN's audited annual financial statements (the "ICN Annual
Statements"), and to enable ICN to meet its timetable for the printing, filing
and public dissemination of the ICN Annual Statements. To this end, Ribapharm
shall deliver to ICN as soon as practicable, and in any event within 75 days
after the end of each fiscal year of Ribapharm (but in no event later than ten
days before Ribapharm intends to file its Annual Financial Statements (as
defined below) with the SEC), (A) drafts of the consolidated financial
statements of Ribapharm (and notes thereto) for such year, setting forth in each
case in comparative form the consolidated figures (and notes thereto) for the
previous fiscal year and all in reasonable detail and prepared in accordance
with Regulation S-X and (B) a discussion and analysis by management of
Ribapharm's consolidated financial condition and results of operations for such
year, including, without limitation, an explanation of any material adverse
change from the immediately preceding fiscal year, all in reasonable detail and
prepared in accordance with Item 303(a) of Regulation S-K. The information set
forth in (A) and (B) above is herein referred to as the "Annual Financial
Statements." Ribapharm shall deliver to ICN all revisions to such drafts as soon
as any such revisions are prepared or made. No later than the earlier of (1)
five Business Days prior to the date Ribapharm files its Annual Report on Form
10-K with the SEC or otherwise makes its Annual Financial Statements publicly
available or (2) five Business Days prior to the date on which ICN has notified
Ribapharm that it intends to file its Annual Report on Form 10-K with the SEC
(but in no event earlier than the 5th day before ICN's Annual Report on Form
10-K is required to be filed with the SEC), Ribapharm shall deliver to ICN the
final form of the Annual Financial Statements certified by the chief financial
officer of Ribapharm as presenting fairly, in all material respects, the
financial condition and results of operations of Ribapharm and its Subsidiaries;
provided that ICN and Ribapharm financial representatives shall actively consult
with each other regarding any changes (whether or not substantive) which
Ribapharm may consider making to its Annual Financial Statements and related
disclosures prior to the actual filing of its Annual Report on Form 10-K with
the SEC. The Annual Financial Statements shall also be accompanied by an opinion
thereon by Ribapharm's independent certified public accountants.

                  (vi) Ribapharm shall deliver to ICN all Quarterly and Annual
Financial Statements of each Ribapharm Affiliate (which (a) Ribapharm
consolidates for financial accounting purposes and (b) is itself required to
file financial statements with the SEC or otherwise make such financial
statements publicly available) with such financial statements to be provided in
the same manner and detail and on the same time schedule as those financial
statements of Ribapharm required to be delivered to ICN pursuant to this Section
5.1.

                  (vii) Ribapharm shall, and shall cause each Ribapharm
Affiliate which files information with the SEC, to deliver to ICN: (A) as soon
as the same are prepared, substantially final drafts of: (x) all reports,
notices and proxy and information statements to be sent or made

                                      -13-
<PAGE>   15
available by Ribapharm or any Ribapharm Affiliate to their security holders, (y)
all regular, periodic and other reports to be filed under Sections 13, 14 and 15
of the Exchange Act (including Reports on Forms 10-K, 10-Q and 8-K and Annual
Reports to Shareholders), and (z) all registration statements and prospectuses
to be filed by Ribapharm or any Ribapharm Affiliate with the SEC or any
securities exchange pursuant to the listed company manual (or similar
requirements) of such exchange (collectively, the documents identified in
clauses (x), (y) and (z) are referred to herein as "Ribapharm Public Filings"),
and (B) as soon as practicable, but in no event later than one Business Day
prior to the date the same are printed, sent or filed, whichever is earliest,
final copies of all such Ribapharm Public Filings; provided that Ribapharm may
continue to revise such Ribapharm Public Filings prior to the filing thereof in
order to make corrections and changes which corrections and changes shall be
delivered by Ribapharm to ICN as soon as practicable; and, provided, further,
that ICN and Ribapharm financial representatives shall actively consult with
each other regarding any changes (whether or not substantive) which Ribapharm
may consider making to any of its Ribapharm Public Filings and related
disclosures prior to any anticipated filing with the SEC.

                  (viii) With reasonable promptness, Ribapharm shall deliver to
ICN such additional financial and other information and data with respect to
Ribapharm and its Subsidiaries and their business, properties, financial
positions, results of operations and prospects as from time to time may be
reasonably requested by ICN.

                  (ix) ICN agrees to provide to Ribapharm all information
relating to ICN or any ICN Affiliate that Ribapharm reasonably requests in
connection with any Ribapharm Public Filings or that, in the judgment of
Ribapharm's legal staff, is required to be disclosed or incorporated by
reference therein under any law, rule or regulation. ICN agrees that such
information shall be provided by ICN in a timely manner on the dates reasonably
requested by Ribapharm (which may be earlier than the dates on which ICN
otherwise would be required hereunder to have such information available) to
enable Ribapharm to prepare, print and release all Ribapharm Public Filings on
such dates as Ribapharm shall determine. If and to the extent reasonably
requested by Ribapharm, ICN agrees that it shall diligently and promptly review
all drafts of such Ribapharm Public Filings and prepare in a diligent and timely
fashion any portion of such Ribapharm Public Filing pertaining to ICN or any ICN
Affiliate.

                  (x) Ribapharm shall authorize Ribapharm's Auditors to make
available to ICN's Auditors both the personnel who performed or are performing
the annual audit of Ribapharm and work papers related to the annual audit of
Ribapharm, in all cases within a reasonable time prior to the date of
Ribapharm's Auditors' opinion on Ribapharm's audited financial statements, so
that ICN's Auditors are able to perform the procedures they consider necessary
to take responsibility for the work of Ribapharm's Auditors as it relates to
ICN's Auditors' report on ICN's statements, all within sufficient time to enable
ICN to meet its timetable for the printing, filing and public dissemination of
the ICN Annual Statements.

                  (xi) Ribapharm shall provide ICN's internal auditors access to
Ribapharm's and its Subsidiaries, books and records so that ICN may conduct
reasonable audits relating to the

                                      -14-
<PAGE>   16
financial statements provided by Ribapharm pursuant hereto as well as to the
internal accounting controls and operations of Ribapharm and its Subsidiaries.

                  (xii) Ribapharm shall give ICN as much prior notice as
reasonably practical of any proposed determination of, or any significant
changes in, its accounting estimates or accounting principles from those in
effect on the date hereof. Ribapharm will consult with ICN and, if requested by
ICN, Ribapharm will consult with ICN's independent public accountants with
respect thereto.

                  (xiii) Ribapharm shall, and shall cause each Ribapharm
Affiliate to, maintain a system of internal accounting controls that will
provide reasonable assurance that (A) Ribapharm's and such Ribapharm Affiliate's
books, records and accounts fairly reflect all transactions and dispositions of
assets and (B) the specific objectives of accounting control are achieved.

                  (xiv) Ribapharm shall cooperate fully, and cause its
accountants to cooperate, with ICN to the extent reasonably requested by ICN in
the preparation of ICN's public earnings releases, Quarterly Reports on Form
10-Q, Annual Reports to Shareholders, Annual Reports on Form 10-K, any Current
Reports on Form 8-K and any other proxy, information and registration
statements, reports, notices, prospectuses and any other filings made by ICN
with the SEC, any national securities exchange or otherwise made publicly
available (collectively, "ICN Public Filings"). Ribapharm agrees to provide to
ICN all information relating to Ribapharm or any Ribapharm Affiliate that ICN
reasonably requests in connection with any ICN Public Filings or that, in the
judgment of ICN's legal staff, is required to be disclosed or incorporated by
reference therein under any law, rule or regulation. Such information shall be
provided by Ribapharm in a timely manner on the dates reasonably requested by
ICN (which may be earlier than the dates on which Ribapharm otherwise would be
required hereunder to have such information available) to enable ICN to prepare,
print and release all ICN Public Filings on such dates as ICN shall determine.
Ribapharm shall cause its accountants to consent to any reference to them as
experts in any ICN Public Filings required under any law, rule or regulation. If
and to the extent reasonably requested by ICN, Ribapharm shall diligently and
promptly review all drafts of such ICN Public Filings and prepare in a diligent
and timely fashion any portion of such ICN Public Filing pertaining to Ribapharm
or any Ribapharm Affiliate. Prior to any printing or public release of any ICN
Public Filing, an appropriate executive officer of Ribapharm shall, if requested
by ICN, certify that the information relating to Ribapharm, any Ribapharm
Affiliate or the Ribapharm Business in such ICN Public Filing is accurate, true
and correct in all material respects. Unless required by law, rule or
regulation, Ribapharm shall not publicly release any financial or other
information which conflicts with the information with respect to Ribapharm, any
Ribapharm Affiliate or the Ribapharm Business that is included in any ICN Public
Filing without ICN's prior written consent. Prior to the release or filing
thereof, ICN shall provide Ribapharm with a draft of any portion of a ICN Public
Filing containing information relating to Ribapharm, any Ribapharm Affiliate or
the Ribapharm Business and shall give Ribapharm an opportunity to review such
information and comment thereon; provided that ICN shall determine in its sole
discretion the final form and content of all ICN Public Filings.

                                      -15-
<PAGE>   17
                  (xv) ICN agrees that it shall cooperate fully, and cause its
accountants to cooperate fully, with Ribapharm to the extent reasonably
requested by Ribapharm in the preparation of any Ribapharm Public Filings.

                  (xvi) Prior to the release or filing thereof, Ribapharm shall
provide ICN with a draft of any portion of a Ribapharm Public Filing containing
information relating to ICN or any ICN Affiliate and shall give ICN an
opportunity to review such information and comment thereon; provided that
Ribapharm shall determine in its sole discretion the final form and content of
all Ribapharm Public Filings.

Nothing in this Section 5.1 shall require Ribapharm to violate any agreement
with any of its customers regarding the confidentiality of commercially
sensitive information relating to that customer or its business; provided that
in the event that Ribapharm would otherwise be required under this Section 5.1,
but for such agreement, to disclose any such information, Ribapharm shall use
all commercially reasonable efforts to seek to obtain such customer's consent to
the disclosure of such information.

         5.2. OTHER COVENANTS. Ribapharm hereby covenants and agrees that, for
so long as ICN beneficially owns at least 10% of the outstanding shares of
Ribapharm Common Stock, Ribapharm shall not, without the prior written consent
of ICN (which it may withhold in its sole and absolute discretion), take, or
cause to be taken, directly or indirectly, any action, including making or
failing to make any election under the law of any state, which has the effect,
directly or indirectly, of restricting or limiting the ability of ICN to freely
sell, transfer, assign, pledge or otherwise dispose of shares of Ribapharm
Common Stock or would restrict or limit the rights of any transferee of ICN as a
holder of Ribapharm Common Stock. Without limiting the generality of the
foregoing, Ribapharm shall not, without the prior written consent of ICN (which
it may withhold in its sole and absolute discretion), take any action, or take
any action to recommend to its stockholders any action, which would among other
things, limit the legal rights of, or deny any benefit to, ICN as a Ribapharm
stockholder in a manner not applicable to Ribapharm stockholders generally.

         5.3 TAX-FREE SPIN-OFF. Ribapharm hereby covenants and agrees that for
six years from the date of this Agreement, Ribapharm shall not, without the
prior written consent of ICN (which it may withhold in its sole and absolute
discretion), (A) issue any shares of Ribapharm Capital Stock or any rights,
warrants or options to acquire Ribapharm Capital Stock (including, without
limitation, securities convertible or exchangeable for Ribapharm Capital Stock),
if after giving effect to such issuances and considering all of the shares of
Ribapharm Capital Stock acquirable pursuant to such rights, warrants and options
to be outstanding on the date of such issuance (whether or not then
exercisable), ICN would cease to beneficially own at least 80% of the voting
power of the outstanding shares of Ribapharm Capital Stock and at least 80% of
the number of shares of each class of non-Voting Ribapharm Capital Stock or (B)
take or cause to be taken, any action, or do, or cause to be done, anything
which will cause the Distribution to fail to qualify as a tax-free event under
Section 355(a) of the Internal Revenue Code. ICN and Ribapharm agree that ICN
may apply to any court of law or equity of competent jurisdiction (without
posting any bond or deposit) for specific performance and/or other

                                      -16-
<PAGE>   18
injunctive relief to prevent any breach of this Section 5.3. This Section 5.3
shall terminate, become null and void and make no further effect if ICN takes
any action that has the effect that ICN cease to beneficially own at least 80%
of the voting power of the outstanding shares of Ribapharm Capital Stock and at
least 80% of the number of shares of each class of non-voting Ribapharm Capital
Stock

         5.4 ALLOCATION OF BENEFITS COVENANT. ICN and Ribapharm hereby agree to
enter into an agreement, prior to the completion of the Distribution, to
equitably allocate existing employee and director options to acquire shares of
ICN Common Stock between new options to acquire ICN Common Stock and options to
acquire Ribapharm Class A Common Stock, substantially as described in the IPO
Registration Statement.

         5.5. TAX SHARING AGREEMENT COVENANT. ICN and Ribapharm hereby covenant
and agree to enter into a Tax Sharing Agreement, concurrent with this Agreement,
to provide for and agree upon the allocation between the parties of liabilities
for Taxes arising prior to, as a result of, and subsequent to the Distribution,
and to provide for and agree upon other matters relating to Taxes.

         5.6. COVENANT REGARDING RIGHTS TO TIAZOLE AND ADENAZOLE. ICN hereby
Covenants and agrees to take all required actions to cause ICN Yugoslavia to
transfer or license all right, title and interest in Tiazole and Adenazole to
Ribapharm, or if all right, title, and interest in Tiazole and Adenazole to
Ribapharm, or if all right, title and interest in Tiazole and Adenazole is
deemed to have reverted to ICN, to transfer all right, title and interest in
Tiazole and Adenazole to ICN.

                  ICN shall retain the sole right and obligation to pursue
claims regarding ownership of right, title and interest in Tiazole and Adenazole
(the "Yugoslavia Claim"); provided, however, that ICN's rights and obligation to
pursue the Yugoslavia Claim under this provision may be assigned to ICN
International Ltd. in the event of an initial public offering of ICN
International Ltd.

6.       INDEMNIFICATION.

         6.1. INDEMNIFICATION BY RIBAPHARM. Subject to Section 6.3, Ribapharm
shall indemnify, defend and hold harmless ICN, all ICN Affiliates and each of
their respective directors, officers and employees (in their capacities as
such), from and against:

         (a) all Losses relating to, arising out of, or due to, directly or
indirectly, any breach by Ribapharm or any Ribapharm Affiliate of any of the
provisions of this Agreement;

         (b) all Losses relating to, arising out of, or due to, directly or
indirectly, any incorrect, inaccurate or incomplete financial and other
information provided by Ribapharm or any Ribapharm Affiliate to ICN pursuant to
Section 5.1 of this Agreement; and

                                      -17-
<PAGE>   19
         (c) all Losses that result from any Third-Party Claim arising out of
the business or operation of the Ribapharm Business.

         6.2. INDEMNIFICATION BY ICN. Subject to Section 6.3, ICN shall
indemnify, defend, and hold harmless Ribapharm, all Ribapharm Affiliates, and
each of their respective directors, officers and employees (in their capacities
as such), from and against:

         (a) all Losses relating to, arising out of, or due to, directly or
indirectly, any breach by ICN or any ICN Affiliate of any of the provisions of
this Agreement;

         (b) all Losses relating to, arising out of, or due to, directly or
indirectly, any incorrect, inaccurate or incomplete financial and other
information provided by ICN or any ICN Affiliate to Ribapharm pursuant to
Section 5.1 of this Agreement;

         (c) all Losses relating to, arising out of, or due to, directly or
indirectly, any expenses, monetary judgment or settlement incurred in connection
with the pending civil lawsuit by the SEC against ICN and related parties in the
United States District Court for the Central District of California, the current
criminal investigation of ICN and related parties by a Grand Jury (in
conjunction with the U.S. Attorney's Office) in the United States District Court
for the Central District of California or the litigation involving the Republic
of Serbia, the Federal Republic of Yugoslavia and the State Health Fund of
Serbia relating to ICN's interest in ICN Yugoslavia; and

         (d) all Losses that result from any Third-Party Claim arising out of
the business or operation of the ICN Business.

         6.3.     OTHER LIABILITIES.

         (a) Except as provided in Section 6.4, this Section 6 shall not be
applicable to any Tax-Related Losses, which shall be governed by the Tax Sharing
Agreement.

         (b) This Section 6 shall not be applicable to any Losses relating to,
arising out of, or due to any breach of the provisions of any other contract,
agreement or understanding between ICN or any ICN Affiliate, on the one hand,
and Ribapharm or any Ribapharm Affiliate, on the other hand, which Losses shall
be governed by the terms of such contract, agreement or understanding.

         6.4.     PROCEDURE FOR INDEMNIFICATION INVOLVING THIRD-PARTY CLAIMS.

         (a) Notice of Claim. If any Indemnitee receives notice of the assertion
of any Third-Party Claim with respect to which an Indemnifying Party is
obligated under this Agreement to provide indemnification, such Indemnitee shall
give such Indemnifying Party notice thereof (together with a copy of such
Third-Party Claim, process or other legal pleading) promptly after becoming
aware of such Third-Party Claim; provided, however, that the failure of any
Indemnitee to give notice as provided in this Section shall not relieve any
Indemnifying Party of its obligations under this Section 6, except to the extent
that such Indemnifying Party is actually prejudiced by

                                      -18-
<PAGE>   20
such failure to give notice. Such notice shall describe such Third-Party Claim
in reasonable detail.

         (b) Obligation of Indemnifying Party. An Indemnifying Party, at such
Indemnifying Party's own expense and through counsel chosen by such Indemnifying
Party (which counsel shall be reasonably acceptable to the Indemnitee), may
elect to defend any Third-Party Claim. If an Indemnifying Party elects to defend
a Third-Party Claim, then, within ten Business Days after receiving notice of
such Third-Party Claim (or sooner, if the nature of such Third-Party Claim so
requires), such Indemnifying Party shall notify the Indemnitee of its intent to
do so, and such Indemnitee shall cooperate in the defense of such Third-Party
Claim. Such Indemnifying Party shall pay such Indemnitee's reasonable
out-of-pocket expenses incurred in connection with such cooperation. Such
Indemnifying Party shall keep the Indemnitee reasonably informed as to the
status of the defense of such Third-Party Claim. After notice from an
Indemnifying Party to an Indemnitee of its election to assume the defense of a
Third-Party Claim, such Indemnifying Party shall not be liable to such
Indemnitee under this Section 6 for any legal or other expenses subsequently
incurred by such Indemnitee in connection with the defense thereof other than
those expenses referred to in the preceding sentence; provided, however, that
such Indemnitee shall have the right to employ one law firm as counsel, together
with a separate local law firm in each applicable jurisdiction ("Separate
Counsel"), to represent such Indemnitee in any action or group of related
actions (which firm or firms shall be reasonably acceptable to the Indemnifying
Party) if, in such Indemnitee's reasonable judgment at any time, either a
conflict of interest between such Indemnitee and such Indemnifying Party exists
in respect of such claim, or there may be defenses available to such Indemnitee
which are different from or in addition to those available to such Indemnifying
Party and the representation of both parties by the same counsel would be
inappropriate, and in that event the reasonable fees and expenses of such
Separate Counsel shall be paid by such Indemnifying Party (it being understood,
however, that the Indemnifying Party shall not be liable for the expenses of
more than one Separate Counsel (excluding local counsel) with respect to any
Third-Party Claim (even if against multiple Indemnitees)). If an Indemnifying
Party elects not to defend against a Third-Party Claim, or fails to notify an
Indemnitee of its election as provided in this Section 6.4 within the period of
ten Business Days described above, the Indemnitee may defend, compromise, and
settle such Third-Party Claim and shall be entitled to indemnification hereunder
(to the extent permitted hereunder) on an as incurred basis; provided, however,
that no such Indemnitee may compromise or settle any such Third-Party Claim
without the prior written consent of the Indemnifying Party, which consent shall
not be unreasonably withheld or delayed. Notwithstanding the foregoing, the
Indemnifying Party shall not, without the prior written consent of the
Indemnitee, (i) settle or compromise any Third-Party Claim or consent to the
entry of any judgment which does not include as an unconditional term thereof
the delivery by the claimant or plaintiff to the Indemnitee of a written release
from all liability in respect of such Third-Party Claim or (ii) settle or
compromise any Third-Party Claim in any manner that would be reasonably likely
to have a material adverse effect on the Indemnitee.

         (c) Joint Defense of Certain Claims. Notwithstanding the provisions of
Section 6.4(b), ICN and Ribapharm shall jointly control the defense of, and
cooperate with each other with respect to defending, any Third-Party Claim with
respect to which each party is claiming that it is

                                      -19-
<PAGE>   21
entitled to indemnification under Section 6.1 or 6.2. If either ICN or Ribapharm
fails to defend jointly any such Third-Party Claim, the other party shall solely
defend such Third-Party Claim and the party failing to defend jointly shall use
all commercially reasonable efforts to cooperate with the other party in its
defense of such Third-Party Claim; provided, however, that neither party may
compromise or settle any such Third-Party Claim without the prior written
consent of the other party, which consent shall not be unreasonably withheld or
delayed. All costs and expenses of either party in connection with, and during
the course of, the joint control of the defense of any such Third-Party Claim
shall be initially paid by the party that incurs such costs and expenses. Such
costs and expenses shall be reallocated and reimbursed in accordance with the
respective indemnification obligations of the parties on a periodic basis (but
in no event later than the conclusion of the defense of such Third-Party Claim).

         6.5. PROCEDURE FOR INDEMNIFICATION NOT INVOLVING THIRD-PARTY CLAIMS. If
any Indemnitee desires to assert against an Indemnifying Party any claim for
indemnification under this Section 6 other than a Third-Party Claim (a "Claim"),
the Indemnitee shall deliver to the Indemnifying Party notice of its demand for
satisfaction of such Claim (a "Request"), specifying in reasonable detail the
amount of such Claim and the basis for asserting such Claim. Within 30 days
after the Indemnifying Party has been given a Request, the Indemnifying Party
shall either (i) satisfy the Claim requested to be satisfied in such Request by
delivering to the Indemnitee payment by wire transfer or a certified or bank
cashier's check payable to the Indemnified Party in immediately available funds
in an amount equal to the amount of such Claim, or (ii) notify the Indemnitee
that the Indemnifying Party contests such Claim by delivering to the Indemnitee
a Dispute Notice, stating that the Indemnifying Party objects to such Claim and
specifying in reasonable detail the basis for contesting such Claim. Any dispute
described in clause (ii) of this Section 6.5 shall be subject to the provisions
of Section 7.1.

         6.6. EXCLUSIVE REMEDIES. Except for the right to pursue equitable
remedies, the remedies provided in this Section 6 shall be deemed the sole and
exclusive remedies of the parties with respect to the subject matters of the
indemnification provisions of this Section 6.

7.       MISCELLANEOUS.

         7.1. DISPUTE RESOLUTION. Resolution of any and all disputes arising
from or in connection with this Agreement other than the provisions of Section
5.3, whether based on contract, tort, or otherwise (collectively, "Disputes"),
shall be exclusively governed by and settled in accordance with the provisions
of this Section 7.1. The parties hereto shall use all commercially reasonable
efforts to settle all Disputes without resorting to mediation, arbitration,
litigation or other third party dispute resolution mechanisms. If any Dispute
remains unsettled, the parties hereby agree to mediate such Dispute using a
mediator reasonably acceptable to all parties involved in such Dispute. If the
parties are unable to resolve such dispute through mediation, each Party will be
free to commence litigation proceedings for the resolution thereof. No Party
shall be entitled to consequential, special, exemplary or punitive damages.

be effective only if it is in writing signed by the party against which such
waiver is to be asserted. Unless otherwise expressly provided in this Agreement,
no delay or omission on the part of any party in exercising any right or
privilege under this Agreement shall operate as a waiver thereof, nor shall any

other or further exercise thereof or the exercise of any other right or
privilege under this Agreement. No failure by either party to take any action or
assert any right or privilege hereunder shall be deemed to be a waiver of such

(including reasonable attorneys' fees) caused by any breach of any provision of

other rights existing in its favor. Each of ICN and Ribapharm acknowledges and
agrees that under certain circumstances the breach by ICN or any of its
Affiliates or Ribapharm or any of its Affiliates of a term or provision of this
Agreement will materially and irreparably harm the other party, that money

non-defaulting party, in its sole discretion and in addition to its rights under
this Agreement and any other remedies it may have at law or in equity, may apply
to any court of law or equity of competent jurisdiction (without posting any
bond or deposit) for specific performance and/or other injunctive relief in

the conditions set forth in this Agreement and in consideration of the Service
Charges described below, ICN agrees to provide to Ribapharm, and Ribapharm
agrees to purchase from ICN, the services described on Schedule I hereto and

certain regulatory affairs services. Unless otherwise specifically agreed by ICN

      Section 2.02. ADDITIONAL SERVICES. In addition to the Services to be
provided by ICN pursuant to Section 2.01, if requested by Ribapharm, and to the
extent that ICN and Ribapharm may mutually agree in writing, ICN shall provide

performed if its failure to do so is caused by or results from any act of God,

third party providers of services to ICN. Each party will notify the other party
of any such event affecting Services to it is required to perform. Each party

                                 SERVICE CHARGES

      Section 3.01. SERVICE CHARGES. (a) The charge for each Service provided
hereunder directly by Ribapharm or ICN shall be equal to all costs reasonably
incurred by Ribapharm or ICN in providing such Service. Such costs shall
include, but are not limited to, appropriate allocation of overhead costs,
personnel costs (e.g., compensation and fringe benefits), travel, and office
costs associated with functions performing such Services.

      (b) The charge for each Outsourced Service provided to Ribapharm hereunder
shall be equal to all costs reasonably incurred by ICN in providing such
Outsourced Service, including, without limitation, any reasonable third-party
costs and expenses incurred by ICN on behalf of Ribapharm. If ICN incurs
third-party costs or expenses on behalf of Ribapharm as well as any ICN Entity,
ICN will allocate any such costs or expenses in good faith between Ribapharm and
the various ICN Entities on behalf of which such costs or expenses were
incurred. ICN shall apply usual and accepted accounting conventions in making
such allocations and ICN or its agents shall keep and maintain such books and
records as may be reasonably necessary to make such allocations. ICN shall make
copies of such books and records available to Ribapharm upon request and with
reasonable notice.

      (c) The parties intend that the Service charges referred to in paragraphs
(a) and (b) above (collectively, the "Service Charges") will allow ICN to
recover the fully allocated costs of providing the Services and Outsourced
Services hereunder plus all out-of-pocket, third-party costs, charges and
expenses, but without any profit to ICN.

      Section 3.02. INVOICING AND SETTLEMENT OF COSTS. (a) The party providing
each Service shall invoice the party receiving the Service for all Service
Charges for each calendar month within thirty (30) days following the end of
such month, provided that any failure to provide an invoice within such time
period shall not relieve the party receiving such Service of its obligation to
pay an invoice received after such date. All invoices shall include a reasonably
detailed description of the Services performed.

      (b) Subject to Section 3.02(c) below, the party receiving such Service
shall pay within 30 days following its receipt of any invoice pursuant to
paragraph (a), without set-off, all amounts invoiced during the preceding
calendar month. If the party receiving such Service fails to pay any undisputed
monthly payment within 60 days following its receipt of any invoice pursuant to
paragraph (a), such party shall pay, in addition to the amount indicated in such
invoice, a rate of interest equal to the LIBOR Rate plus 200 basis points per
annum on such amount for the period such amount remains unpaid.

      (c) In the event of a dispute as to the propriety of any amount invoiced
pursuant to paragraph (a) above, the party receiving the Service shall pay all
undisputed amounts, but shall be entitled to withhold payment of any amount in
dispute (and shall not be obligated to pay interest on the amount so withheld)
and shall endeavor to notify the party providing the Service within 10 Business
Days from receipt of any disputed invoice of the disputed amount and the reasons
each such charge is disputed by the party receiving the Service, provided that
the failure to so notify the party providing the Service within such time period
shall not prevent the party receiving the Service from disputing such invoice.
The party providing the Service shall provide to the party receiving the
Service, or shall cause its Subsidiaries to so provide, records relating to the
disputed amount so as to enable the parties to resolve the dispute. The parties
shall use reasonable efforts to resolve any such dispute promptly.

      (d) Any invoice or payment not disputed in writing by either party within
180 days of such invoice or payment, as the case may be, shall be considered
final and no longer subject to adjustment.

                                   ARTICLE IV
                                   FACILITIES

      Section 4.01. ICN USE OF COSTA MESA FACILITY. Subject to Section 4.02,
Ribapharm hereby grants to ICN and ICN hereby accepts from Ribapharm an
exclusive license to use the portion of Ribapharm's Costa Mesa Facility used
primarily by ICN as of the date of the Initial Public Offering as described in
Schedule II hereto (the "ICN Space") and a non-exclusive license to use the
portion of the common areas of the Costa Mesa Facility relating to or useful in
connection with the use by ICN of the ICN Space as described in Schedule III
hereto (the "ICN Common Areas") commencing on the date of the Initial Public
Offering and terminating on December 31, 2003 or such earlier date as specified
by ICN pursuant to Section 4.02. ICN shall not have any right to renew such
rights of use past December 31, 2003.

      Section 4.02. REDUCTIONS IN ICN SPACE AND ICN COMMON AREAS. At least ten
(10) days prior to the commencement of each calendar month, ICN may give notice
to Ribapharm of its intention to terminate its exclusive license to use all or
any portion of the ICN Space, in which case ICN's exclusive license to use such
portion of the ICN Space pursuant to

                                      -6-
<PAGE>   8
Section 4.01 shall terminate as of the commencement of such month and ICN's
non-exclusive license to use the portions of the ICN Common Areas which do not
relate to and are not useful in connection with any remaining portion of the ICN
Space shall terminate as of the commencement of such month. In addition, ICN
may, by giving Ribapharm at least 30 days notice, elect to terminate all of its
rights of use pursuant to Section 4.01, as of a date specified in such notice.

      Section 4.03. REIMBURSEMENTS TO RIBAPHARM. (a) ICN shall be liable, on a
monthly basis, to Ribapharm for ICN's share of Ribapharm's Facility Costs in an
amount (the "ICN Costs Share") equal to Ribapharm's Facility Costs for the Costa
Mesa Facility for each month multiplied by a fraction, the numerator of which is
the square footage comprising the portion of the ICN Space (as reduced pursuant
to Section 4.02) as to which ICN had the exclusive license to use as of the
first day of that month and the denominator of which is the total square footage
(excluding common areas) comprising the Costa Mesa Facility. In the case of any
month during which all of ICN's rights of use pursuant to Section 4.01 commence
or terminate, the ICN Costs Share shall be reduced pro rata based upon the
percentage of the days in such month during which ICN's rights of use pursuant
to Section 4.01 were in effect.

      (b) Ribapharm shall invoice ICN for the ICN Costs Share for each month
within thirty (30) days following the end of such month, provided that any
failure by Ribapharm to provide an invoice within such time period shall not
relieve ICN of its obligation to pay an invoice received after such date. All
invoices shall include a reasonably detailed description of Ribapharm's Facility
Costs and the method of calculation of the ICN Costs Share. If Ribapharm is
unable to determine the exact amount of Ribapharm's Facility Costs for the Costa
Mesa Facility it may in good faith estimate such amount, with appropriate
adjustments when such amount is determined.

      (c) Subject to Section 4.03(d) below, ICN shall pay within 15 days
following its receipt of any invoice from Ribapharm pursuant to paragraph (b),
without set-off, all amounts invoiced by Ribapharm pursuant to paragraph (b)
above. If ICN fails to pay any invoice within 30 days following its receipt
thereof, ICN shall pay, in addition to the amount indicated in such invoice, the
LIBOR Rate plus 200 basis points interest per annum on such amount for the
period such amount remains unpaid. If ICN fails to pay any invoice within 60
days following its receipt thereof or if ICN defaults in observing or fulfilling
any of its other obligations under this License to be observed or fulfilled by
ICN for a period of fifteen (15) days after notice from Ribapharm of such
default, Ribapharm may, upon the expiration of such applicable period, terminate
the licenses granted by this Article IV by delivering notice thereof to ICN, and
the term of such licenses shall cease and expire on the termination date
specified in said notice with the same force and effect as if such date were
originally provided herein as the expiration date for such licenses, and ICN
shall be liable for any and all sums or damages to which Ribapharm may lawfully
be entitled at law or in equity.

      (d) In the event of a dispute as to the propriety of the amount invoiced,
ICN shall pay all undisputed amounts, but shall be entitled to withhold payment
of any amount which ICN may in its reasonable judgment believe is in dispute
(and shall not be obligated to pay interest on the amount so withheld) and shall
endeavor to notify Ribapharm within 10 Business Days from receipt of any
disputed invoice of the disputed amount and the reasons each such charge is
disputed by ICN, provided that the failure to so notify Ribapharm within such
time period shall

                                      -7-
<PAGE>   9
not prevent ICN from disputing such invoice. Ribapharm shall provide to ICN
records relating to the disputed amount so as to enable the parties to resolve
the dispute. The parties shall use reasonable efforts to resolve any such
dispute promptly.

      (e) Any invoice not disputed in writing within 60 days of receipt of such
invoice, shall be considered final and no longer subject to adjustment.

      Section 4.04. FURTHER OBLIGATIONS RELATING TO THE FACILITIES. (a) The
licenses granted to ICN under this Article IV afford ICN a personal privilege
with respect to the use and occupancy of the ICN Space and the ICN Common Areas.
Neither license is intended to be nor shall they in any way be deemed to be
lease, sublease or easement. No leasehold interest or other right, title and/or
interest in the ICN Space or the ICN Common Areas, or any part of either, shall
be deemed created or granted to ICN by anything contained herein. The licenses
merely grant to ICN a limited right to enter upon and occupy the ICN Space and
the ICN Common Areas in accordance with the terms and conditions hereof. Without
the prior written consent of Ribapharm, ICN shall not (i) assign any rights or
duties under this Article IV, (ii) sublet any portion of the ICN Space or ICN
Common Areas, (iii) allow any other person to occupy or use the ICN Space or ICN
Common Areas or (iv) encumber, license or otherwise transfer any of ICN's rights
under this Article IV. A consent to one assignment, sublease, occupation
encumbrance or other or use by any other person shall not be a consent to any
subsequent assignment, sublease or occupation or use by another person. Any
assignment or subletting or other transfer by ICN without Ribapharm's prior
written consent shall be void.

      (b) In the event of the destruction or condemnation of all or any portion
of the ICN Space or the ICN Common Areas, ICN's rights of use with respect to
such destroyed or condemned portion pursuant to Section 4.01 shall terminate and
Ribapharm shall have no liability to ICN on account of such destruction or
condemnation.

      (c) ICN shall take good care of the ICN Space and ICN Common Areas and
shall not alter, repair or change the ICN Space or ICN Common Areas without the
prior written consent of Ribapharm.

      (d) All alterations, improvements and changes that ICN may desire to the
ICN Space shall be done at the expense of ICN and shall become the property of
Ribapharm, provided that, at Ribapharm's option, ICN shall, at its expense, and
without damage to the Costa Mesa Facility remove from any portion of the ICN
Space with respect to which ICN's exclusive license pursuant to Section 4.01 has
terminated (to the extent practicable) any such alterations, improvements or
changes. ICN shall not make any such alterations, improvements or changes
without the prior written consent of Ribapharm.

      (e) Any and all damage or injury done to the Costa Mesa Facility by ICN or
any person who may be in or on the ICN Space or ICN Common Areas (with or
without ICN's consent) shall be repaired by ICN at ICN's expense.

      (f) Upon the expiration or earlier termination of the licenses, or any
portion thereof, granted under this Article IV, ICN shall quit and surrender the
ICN Space and/or the ICN Common Areas, or portion thereof, as applicable, in the
same condition as the same were initially delivered to ICN. If ICN shall fail to
so quit and surrender the same, in addition to all other

                                      -8-
<PAGE>   10
rights and remedies available to Ribapharm, ICN shall pay to Ribapharm, for each
day that ICN so fails to quit and surrender the same following the date it was
required to do so, an amount equal to two (2) times the ICN Cost Share payable
hereunder for each such day and all costs and expenses (including, without
limitation, attorneys' fees, court costs and disbursements) incurred by
Ribapharm in enforcing its rights and remedies.

      (g) ICN shall permit Ribapharm and Ribapharm's agents to enter the ICN
Space to inspect, clean, repair, perform janitorial services, perform
maintenance, and make alterations, additions or improvements.

      (h) ICN shall not use or permit the use of the ICN Space or ICN Common
Areas except in accordance with the uses of such areas as of the date of this
Agreement. ICN shall not permit any act, sale or storage in the ICN Space or ICN
Common Areas that may be prohibited under Ribapharm's fire or casualty insurance
policies or under any applicable law or zoning regulations. ICN shall not use or
permit the use of the ICN Space or ICN Common Areas in a manner that shall
result in: (1) waste on the ICN Space or ICN Common Areas; (2) a public or
private nuisance; (3) improper, unlawful or objectionable use; or (4) noises,
odors or vibrations that may disturb other tenants, including Ribapharm. ICN
shall comply with all governmental regulations and statutes affecting the ICN
Space or ICN Common Areas now or in the future.

      (i) ICN waives all claims against Ribapharm for damages to goods or for
injuries to persons on or about the ICN Space or ICN Common Areas from any cause
arising at any time. ICN hereby indemnifies Ribapharm on account of any damage
or injury to any person, or to the goods of any person, arising from the use of
the ICN Space or ICN Common Areas by ICN or any of its employees, guests,
contractors or invitees, or arising from the failure of ICN to keep in good
condition the portion of the ICN Space with respect to which ICN has an
exclusive license. ICN agrees to pay for all damage to the Costa Mesa Facility,
as well as all damage or injury suffered by tenants, occupants, guests or
invitees of the Costa Mesa Facility caused by the misuse or neglect of the ICN
Space or ICN Common Areas by ICN.

      (j) Ribapharm has made and is making no representations or warranties with
respect to the ICN Space, the ICN Common Areas or the Costa Mesa Facility and no
licenses or other rights are acquired by ICN by implication or otherwise except
as expressly set forth herein. ICN shall accept possession of the ICN Space in
the condition that exists on the date of the Initial Public Offering "as is",
and Ribapharm shall have no obligation at any time to perform any work or make
any installation or pay any sums in order to prepare the ICN Space or the ICN
Common Areas (as initially constituted or hereafter constituted) for ICN's
occupancy.

      (k) ICN's obligations under this Article IV shall not be impaired or its
performance excused because of any failure or delay of Ribapharm in providing
any utilities, repairs or services to the ICN Space or ICN Common Areas.

      (l) Ribapharm and ICN each represents and warrants to the other that it
has not dealt with any broker in connection with this Agreement.

                                      -9-
<PAGE>   11
      Section 5.01. LIMITATION OF LIABILITY. (a) Ribapharm agrees that ICN and
each of its Subsidiaries and each of their respective directors, officers,
agents and employees (each, an "ICN Indemnified Person") shall only be liable to
Ribapharm for or in connection with the Services rendered or to be rendered by
any ICN Indemnified Person pursuant to this Agreement, the use by ICN of the ICN
Space or the ICN Common Areas, the transactions contemplated hereby or any ICN
Indemnified Person's actions or inactions in connection with any such Services
or transactions for claims, damages, losses, obligations, liabilities, costs and
expenses (including, without limitation, reasonable attorneys' fees) resulting
from, or arising out of, breach of contract, negligence or willful misconduct on
the part of any ICN Indemnified Person.

      (b) ICN agrees that Ribapharm and each of its respective directors,
officers, agents and employees (each, an "Ribapharm Indemnified Person") shall
only be liable to ICN for or in connection with the Services rendered or to be
rendered by any Ribapharm Indemnified Person pursuant to this Agreement, the
transactions contemplated hereby or any Ribapharm Indemnified Person's actions
or inactions in connection with any such Services or transactions for claims,
damages, losses, obligations, liabilities, costs and expenses (including,
without limitation, reasonable attorneys' fees) resulting from, or arising out
of, breach of contract, negligence or willful misconduct on the part of any
Ribapharm Indemnified Person.

      Section 5.02. INDEMNIFICATION. (a) Ribapharm agrees to indemnify and hold
harmless each ICN Indemnified Person from and against any Losses arising out of
or in connection with Services rendered or to be rendered by any ICN Indemnified
Person pursuant to this Agreement, the transactions contemplated hereby (other
than the transactions contemplated by Article IV hereof which shall be governed
by the indemnification provisions of Article IV) or any ICN Indemnified Person's
actions or inactions in connection with any such Services or transactions except
for claims, damages, losses, obligations, liabilities, costs and expenses
(including, without limitation, reasonable attorneys' fees) resulting from, or
arising out of, breach of contract, negligence or willful misconduct on the part
of any ICN Indemnified Person.

      (b) ICN agrees to indemnify and hold harmless each Ribapharm Indemnified
Person from and against any Losses arising out of or in connection with Services
rendered or to be rendered by any Ribapharm Indemnified Person pursuant to this
Agreement, the transactions contemplated hereby (other than the transactions
contemplated by Article IV hereof which shall be governed by the indemnification
provisions of Article IV) or any Ribapharm Indemnified Person's actions or
inactions in connection with any such Services or transactions except for
claims, damages, losses, obligations, liabilities, costs and expenses
(including, without limitation, reasonable attorneys' fees) resulting from, or
arising out of, breach of contract, negligence or willful misconduct on the part
of any Ribapharm Indemnified Person.

      Section 5.03. PROCEDURE FOR INDEMNIFICATION INVOLVING THIRD-PARTY CLAIMS.
(a) Notice of Claim. If any Indemnitee receives notice of the assertion of any
Third-Party Claim with respect to which an Indemnifying Party is obligated under
this Agreement to provide indemnification, such Indemnitee shall give such
Indemnifying Party notice thereof (together with a copy of such Third-Party
Claim, process or other legal pleading) promptly after becoming aware of such
Third-Party Claim; provided, however, that the failure of any Indemnitee to give
notice as provided in this Section shall not relieve any Indemnifying Party of
its obligations under this Article V (or any other indemnification provision of
this Agreement),

                                      -10-
<PAGE>   12
except to the extent that such Indemnifying Party is actually prejudiced by such
failure to give notice. Such notice shall describe such Third-Party Claim in
reasonable detail.

      (b) Obligation of Indemnifying Party. An Indemnifying Party, at such
Indemnifying Party's own expense and through counsel chosen by such Indemnifying
Party (which counsel shall be reasonably acceptable to the Indemnitee), may
elect to defend any Third-Party Claim. If an Indemnifying Party elects to defend
a Third-Party Claim, then, within ten Business Days after receiving notice of
such Third-Party Claim (or sooner, if the nature of such Third-Party Claim so
requires), such Indemnifying Party shall notify the Indemnitee of its intent to
do so, and such Indemnitee shall cooperate in the defense of such Third-Party
Claim. Such Indemnifying Party shall pay such Indemnitee's reasonable
out-of-pocket expenses incurred in connection with such cooperation. Such
Indemnifying Party shall keep the Indemnitee reasonably informed as to the
status of the defense of such Third-Party Claim. After notice from an
Indemnifying Party to an Indemnitee of its election to assume the defense of a
Third-Party Claim, such Indemnifying Party shall not be liable to such
Indemnitee under this Article V (or any other indemnification provision of this
Agreement) for any legal or other expenses subsequently incurred by such
Indemnitee in connection with the defense thereof other than those expenses
referred to in the preceding sentence; provided, however, that such Indemnitee
shall have the right to employ one law firm as counsel, together with a separate
local law firm in each applicable jurisdiction ("Separate Counsel"), to
represent such Indemnitee in any action or group of related actions (which firm
or firms shall be reasonably acceptable to the Indemnifying Party) if, in such
Indemnitee's reasonable judgment at any time, either a conflict of interest
between such Indemnitee and such Indemnifying Party exists in respect of such
claim, or there may be defenses available to such Indemnitee which are different
from or in addition to those available to such Indemnifying Party and the
representation of both parties by the same counsel would be inappropriate, and
in that event the reasonable fees and expenses of such Separate Counsel shall be
paid by such Indemnifying Party (it being understood, however, that the
Indemnifying Party shall not be liable for the expenses of more than one
Separate Counsel (excluding local counsel) with respect to any Third-Party Claim
(even if against multiple Indemnitees)). If an Indemnifying Party elects not to
defend against a Third-Party Claim, or fails to notify an Indemnitee of its
election as provided in this Article V within the period of ten Business Days
described above, the Indemnitee may defend, compromise, and settle such
Third-Party Claim and shall be entitled to indemnification hereunder (to the
extent permitted hereunder) on an as incurred basis; provided, however, that no
such Indemnitee may compromise or settle any such Third-Party Claim without the
prior written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld or delayed. Notwithstanding the foregoing, the
Indemnifying Party shall not, without the prior written consent of the
Indemnitee, (i) settle or compromise any Third-Party Claim or consent to the
entry of any judgment which does not include as an unconditional term thereof
the delivery by the claimant or plaintiff to the Indemnitee of a written release
from all liability in respect of such Third-Party Claim or (ii) settle or
compromise any Third-Party Claim in any manner that would be reasonably likely
to have a material adverse effect on the Indemnitee.

      (c) Joint Defense of Certain Claims. Notwithstanding the provisions of
Section 5.05(b), ICN and Ribapharm shall jointly control the defense of, and
cooperate with each other with respect to defending, any Third-Party Claim with
respect to which each party is claiming that it is entitled to indemnification
under this Article V (or any other indemnification provision of this Agreement).
If either ICN or Ribapharm fails to defend jointly any such Third-Party

                                      -11-
<PAGE>   13
Claim, the other party shall solely defend such Third-Party Claim and the party
failing to defend jointly shall use all commercially reasonable efforts to
cooperate with the other party in its defense of such Third-Party Claim;
provided, however, that neither party may compromise or settle any such
Third-Party Claim without the prior written consent of the other party, which
consent shall not be unreasonably withheld or delayed. All costs and expenses of
either party in connection with, and during the course of, the joint control of
the defense of any such Third-Party Claim shall be initially paid by the party
that incurs such costs and expenses. Such costs and expenses shall be
reallocated and reimbursed in accordance with the respective indemnification
obligations of the parties on a periodic basis (but in no event later than the
conclusion of the defense of such Third-Party Claim).

      Section 5.04. PROCEDURE FOR INDEMNIFICATION NOT INVOLVING THIRD-PARTY
CLAIMS. If any Indemnitee desires to assert against an Indemnifying Party any
claim for indemnification under this Article V other than a Third-Party Claim (a
"Claim"), the Indemnitee shall deliver to the Indemnifying Party notice of its
demand for satisfaction of such Claim (a "Request"), specifying in reasonable
detail the amount of such Claim and the basis for asserting such Claim. Within
30 days after the Indemnifying Party has been given a Request, the Indemnifying
Party shall either (i) satisfy the Claim requested to be satisfied in such
Request by delivering to the Indemnitee payment by wire transfer or a certified
or bank cashier's check payable to the Indemnified Party in immediately
available funds in an amount equal to the amount of such Claim, or (ii) notify
the Indemnitee that the Indemnifying Party contests such Claim by delivering to
the Indemnitee a Dispute Notice, stating that the Indemnifying Party objects to
such Claim and specifying in reasonable detail the basis for contesting such
Claim. Any dispute described in clause (ii) of this Section 5.04 shall be
subject to the provisions of Section 7.01.

      Section 5.05. EXCLUSIVE REMEDIES. Except for the right to pursue equitable
remedies, the remedies provided in this Article V shall be deemed the sole and
exclusive remedies of the parties with respect to the subject matters of the
indemnification provisions of this Agreement.

                                   ARTICLE VI
                              TERM AND TERMINATION

      Section 6.01. TERM. (a) This Agreement shall commence on the date of the
Initial Public Offering and shall terminate on December 31, 2003 (the "Initial
Term"); provided, however, that ICN and Ribapharm may, by mutual agreement,
provide for the continuation of certain services after the Initial Term.

      (b) The obligation of ICN to provide legal Services under this Agreement
shall automatically terminate on the date that ICN ceases to own at least 50% of
the combined voting power of the outstanding shares of Ribapharm Class A Common
Stock and Ribapharm Class B Common Stock.

      (c) Either party may terminate this Agreement with respect to any one or
more of the Services if the other party shall have failed to perform any of its
material obligations under this Agreement relating to any such Service or
Services, the aggrieved party has notified the other

                                      -12-
<PAGE>   14
party in writing of such failure, and such failure shall have continued for a
period of 30 days after receipt by the other party of notice of such failure.

      (d) Ribapharm may terminate any one of the Services listed on Schedule I
hereto individually upon 30 days written notice to ICN and such termination will
not effect the obligations of the parties under this Agreement regarding any
other Services listed on Schedule I hereto.

      (e)   The provisions of Article IV shall commence and terminate as
provided therein.

      Section 6.02. EFFECT OF TERMINATION. Other than as required by law, upon
termination of any Service pursuant to Section 6.01, ICN will have no further
obligation to provide the terminated Service (or any Service, in the case of
termination of this Agreement) and Ribapharm will have no obligation to pay any
fees relating to such Service or make any other payments hereunder; provided,
however, that notwithstanding such termination, (i) Ribapharm shall remain
liable to ICN for fees owed and payable in respect of any Service provided prior
to the effective date of the termination and (ii) the provisions of Articles
III, IV, V, VI and VII shall survive any such termination.

                                   ARTICLE VII
                                  MISCELLANEOUS

      Section 7.01. DISPUTE RESOLUTION. Resolution of any and all disputes
arising from or in connection with this Agreement, whether based on contract,
tort, or otherwise (collectively, "Disputes"), shall be exclusively governed by
and settled in accordance with the provisions of this Section 7.01. The parties
hereto shall use all commercially reasonable efforts to settle all Disputes
without resorting to mediation, arbitration, litigation or other third party
dispute resolution mechanisms. If any Dispute remains unsettled, the parties
hereby agree to mediate such Dispute using a mediator reasonably acceptable to
all parties involved in such Dispute. If the parties are unable to resolve such
dispute through mediation, each party will be free to commence litigation
proceedings for the resolution thereof. No party shall be entitled to
consequential, special, exemplary or punitive damages.

      Section 7.02. AUTHORITY. Each of the parties hereto represents and
warrants to the other that (a) it has the corporate power and authority to
execute, deliver and perform this Agreement, (b) the execution, delivery and
performance of this Agreement by it has been duly authorized by all necessary
corporate action, (c) it has duly and validly executed and delivered this
Agreement, and (d) this Agreement is a legal, valid and binding obligation,
enforceable against it in accordance with its terms subject to applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting creditors' rights generally and general equity principles. The
representations and warranties contained in this Section 7.02 shall survive the
execution and delivery hereof until the expiration of all applicable statutes of
limitations.

      Section 7.03. COMPLETE AGREEMENT. Except as otherwise set forth in this
Agreement, this Agreement and the exhibits hereto shall constitute the entire
agreement between

                                      -13-
<PAGE>   15
the parties hereto with respect to the subject matter hereof and shall supersede
all prior agreements and understandings, whether written or oral, between the
parties with respect to such subject matter. Notwithstanding anything to the
contrary contained herein, Ribapharm shall not be charged anything under this
Agreement for any Services that are specifically required to be performed under
any other agreement between ICN and Ribapharm and any such other Services shall
be performed and charged for in accordance with the terms of such other
agreement.

      Section 7.04. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of California (without giving
effect to the conflict of laws principles thereof) as to all matters, including
matters of validity, construction, effect, performance and remedies.

      Section 7.05. NOTICES. All Notices and other communications hereunder
shall be in writing and shall be delivered in person, by telecopy, by express or

telecopy or by air courier shall be deemed effective on the first Business Day
at the place at which such notice or communication is received following the day
on which such notice or communication was sent.

      Section 7.06. AMENDMENT AND MODIFICATION. This Agreement may not be
amended or modified in any respect except by a written agreement signed by both
of the parties hereto.

      Section 7.07. BINDING EFFECT; ASSIGNMENT. This Agreement and all of the
provisions hereof shall be binding upon the parties hereto and inure to the
benefit of the parties hereto and their respective successors and permitted
assigns. Except with respect to a merger of either party with another Person,
neither this Agreement nor any of the rights, interests or

                                      -14-
<PAGE>   16
obligations hereunder shall be assigned by either party hereto without the prior
written consent of the other party.

      Section 7.08. THIRD PARTY BENEFICIARIES. The Indemnitees and their
respective successors shall be third party beneficiaries of the indemnification
provisions of Article V, as applicable, and shall be entitled to enforce those
provisions and in connection with such enforcement shall be subject to Section
7.05, in each such case as fully and to the same extent as if they were parties
to this Agreement. Except as provided in the previous sentence, nothing in this
Agreement, express or implied, is intended to or shall confer upon any Person
any legal or equitable right, benefit or remedy of any nature whatsoever under
or by reason of this Agreement, and no Person (other than as provided in the
previous sentence) shall be deemed a third party beneficiary under or by reason
of this Agreement. Each of ICN and Ribapharm acknowledges that the Services
shall be provided only with respect to the business of the other party and its
Subsidiaries as currently operated and as currently projected to be operated or
as mutually agreed by the parties hereto. Each of ICN and Ribapharm shall not
request performance of any Service for the benefit of any entity other than the
other party and its Subsidiaries. Each of ICN and Ribapharm represents and
agrees that the other party will use the Services only in accordance with all
applicable federal, state and local laws and regulations, and in accordance with
past practices. Each party reserves the right to take all actions, including
termination of any particular Service, that it reasonably believes to be
necessary to assure compliance with applicable laws and regulations. Each party
will notify the other party promptly of the reasons for any such termination of
Services.

      Section 7.09.     COUNTERPARTS. This Agreement may be executed in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. The Agreement
may be executed by facsimile signature.

      Section 7.10. WAIVER. The observance of any term of this Agreement may be
waived (either generally or in a particular instance and either retroactively or
prospectively) by the party entitled to enforce such term, but such waiver shall
be effective only if it is in writing signed by the party against which such
waiver is to be asserted. Unless otherwise expressly provided in this Agreement,
no delay or omission on the part of any party in exercising any right or
privilege under this Agreement shall operate as a waiver thereof, nor shall any
waiver on the part of any party of any right or privilege under this Agreement
operate as a waiver of any other right or privilege under this Agreement nor
shall any single or partial exercise of any right or privilege preclude any
other or further exercise thereof or the exercise of any other right or
privilege under this Agreement. No failure by either party to take any action or
assert any right or privilege hereunder shall be deemed to be a waiver of such
right or privilege in the event of the continuation or repetition of the
circumstances giving rise to such right unless expressly waived in writing by
the party against whom the existence of such waiver is asserted.

      Section 7.11. SEVERABILITY. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                                      -15-
<PAGE>   17
      Section 7.12. REMEDIES. Each of ICN and Ribapharm shall be entitled to
enforce its rights under this Agreement specifically, to recover damages and
costs (including reasonable attorneys' fees) caused by any breach of any
provision of this Agreement and to exercise all other rights existing in its
favor. Each of ICN and Ribapharm acknowledges and agrees that under certain
circumstances the breach by ICN or any of its Affiliates or Ribapharm or any of
its Affiliates of a term or provision of this Agreement will materially and
irreparably harm the other party, that money damages will accordingly not be an
adequate remedy for such breach and that the non-defaulting party, in its sole
discretion and in addition to its rights under this Agreement and any other
remedies it may have at law or in equity, may apply to any court of law or
equity of competent jurisdiction (without posting any bond or deposit) for
specific performance and/or other injunctive relief in order to enforce or
prevent any breach of the provisions of this Agreement.

      Section 7.13. PERFORMANCE; NO AGENCY. Each of the parties hereto shall use
all commercially reasonable efforts to cause to be performed all actions,
agreements and obligations set forth herein to be performed by any Affiliate of
such party. Nothing in this Agreement shall constitute or be deemed to
constitute a partnership or joint venture between the parties hereto or
constitute or be deemed to constitute any party the agent or employee of the
other party for any purpose whatsoever and neither party shall have authority or
power to bind the other or to contract in the name of, or create a liability
against, the other in any way or for any purpose.

      Section 7.14. REFERENCES; CONSTRUCTION. The section and other headings and
subheadings contained in this Agreement and the exhibits hereto are solely for
the purpose of reference, are not part of the agreement of the parties hereto,
and shall not in any way affect the meaning or interpretation of this Agreement
or any exhibit hereto. All references to days or months shall be deemed
references to calendar days or months. Unless the context otherwise requires,
any reference to an "Article," "Section" or "Schedule" shall be deemed to refer

"herein" and "hereunder" and words of similar import referring to this Agreement
refer to this Agreement as a whole and not to any particular provision of this
Agreement. Whenever the words "include," or "including" are used in this
Agreement, unless otherwise specifically provided, they shall be deemed to be
followed by the words "without limitation."
