                                       22

Indication in a different therapeutic area from the first Regulatory Approval
for such Drug Product, and the third Regulatory Approval must be for an
indication in a different therapeutic area from the first and second Regulatory
Approval for such Drug Product. By way of example, [***], [***] and [***] would
be considered separate therapeutic areas for the purposes of this Agreement, but
an Indication of combination therapy in [***] would not be considered as a
separate therapeutic area.

     (b) None of the payments listed above shall be payable more than once, and
each shall be payable at the first achievement of a milestone event for the
Compound or Drug Product and shall not be payable again if subsequently a
Combination Product, back-up or another Compound would achieve the same

     (c) All payments shall be made by wire transfer in United States Dollars to
the credit of such bank account as may be designated by Avanir in this Agreement
or in writing to Novartis. Any payment which falls due on a date which is not a
Business Day in Hamilton, Bermuda or Basel, Switzerland may be made on the next
succeeding Business Day in Hamilton, Bermuda or Basel, Switzerland. In the event
that any payment due hereunder is not received by Avanir when due, Novartis
shall pay to Avanir interest charges at a rate equal to the [***]. Such interest
shall be calculated from the date that payment was due until actually received
by Avanir.

     7.5 ROYALTY PAYMENTS

     (a) On a Drug Product by Drug Product basis, with respect to those
countries in which an Avanir Patent with a Valid Claim exists, Novartis or its
Affiliates shall pay to Avanir the following royalties in respect of such
countries:

[***] percent ([***]%) on annual Net Sales up to $[***]

[***] percent ([***]%) on that amount of annual Net Sales that is greater than
$[***] but less than or equal to $[***]

[***] percent ([***]%) on that amount of annual Net Sales greater than $[***]

     (b) In the event that Novartis or its Affiliates determines in its sole
discretion (but only after consultation with Avanir), that it would be necessary
or useful to acquire rights

                                              * Confidential Treatment Requested


                                       23

from one or more Third Parties in order to sell a Drug Product in a country,
then [***] percent ([***]%) of the royalty payable to such Third Party in such
country shall be deductible from the royalties payable to Avanir under this
Agreement. In no event shall this deduction cause the amounts to be paid to
Avanir to be less than [***] percent ([***]%) of the amount otherwise payable to
Avanir pursuant to Section 7.5(a) or Section 7.5(c), as the case may be. In the
event that the amount Novartis or its Affiliates is entitled to deduct hereunder
exceeds the amount of any individual royalty payment due to Avanir, Novartis or
its Affiliates shall be entitled to deduct amounts from any subsequent
payment(s) until the entire amount to which Novartis or its Affiliates is
entitled to deduct has been so deducted.

     (c) On a Drug Product by Drug Product basis, with respect to those
countries in which no Avanir Patents with a Valid Claim exist, Novartis shall
pay to Avanir royalties at [***] percent ([***]%) of the rates set forth in
Section 7.5(a), as reduced by Section 7.5(b), if applicable, in consideration of
Avanir Know-How; provided, however that, should a generic version of a Drug
Product be sold by a Third Party in the same country as a Drug Product, then the
royalty payments set forth in this Section 7.5 for such Drug Product shall
cease.

     (d) On a country-by-country basis, royalties as outlined in this Section
7.5 shall be payable for the term of this Agreement as set out in Article XII
(Term and Termination), on a quarterly basis, within sixty (60) calendar days
after the end of each calendar quarter, and in accordance with Section 16.18.

     7.6 SALES REPORTS

     (a) During the term of this Agreement and after the First Commercial Sale
of a Drug Product, Novartis or its Affiliates shall furnish or cause to be
furnished to Avanir on a quarterly basis a Sales Report covering each calendar
quarter (each such calendar quarter being sometimes referred to herein as a
"reporting period"). With respect to sales of Drug Products invoiced in United
States Dollars, the Net Sales amounts and the amounts due to Avanir hereunder
shall be expressed in United States Dollars. With respect to sales of Drug
Products invoiced in a currency other than United States Dollars, the Net Sales
and amounts due to Avanir hereunder shall be expressed in the domestic currency
of the Party making the sale, together with the United States Dollar equivalent
of the amount payable to Avanir, calculated using the then-current Novartis
standard exchange rate methodology applied in its external reporting (which is
ultimately based on official rates such as Reuters and the European Central
Bank) for the conversion of foreign currency sales into United States

                                              * Confidential Treatment Requested


                                       24

Dollars. Novartis shall furnish to Avanir appropriate evidence of payment of any
tax or other amount required by applicable laws or regulations to be deducted
from any royalty payment, including any tax or withholding levied by a foreign
taxing authority in respect of the payment or accrual of any royalty. Sales
Reports shall be due on the thirtieth (30th) Business Day following the close of
each reporting period. Novartis or its Affiliates shall keep accurate records in
sufficient detail to enable the amounts due hereunder to be determined and to be
verified by Avanir.

     (b) If at any time legal restrictions prevent the prompt remittance of any
payments with respect to any country of the Territory where a Drug Product is
sold, Novartis or its Affiliates or its sublicensees shall convert the amount
owed into US Dollars and remit payment from another source of funds.

     7.7 AUDIT

     (a) Avanir shall have the right for a period of three (3) years after
receiving any report or statement with respect to royalties due and payable to
appoint an Auditor to inspect the relevant records of Novartis or its Affiliates
to verify such reports, statements, records or books of accounts, as applicable.

Novartis or its Affiliates shall make its records available for inspection by
the Auditor during regular business hours at such place or places where such
records are customarily kept, upon receipt of reasonable advance notice from
Avanir, solely to verify the accuracy of Novartis' or its Affiliates' sales
reports, payments records or books of accounts and Novartis' or its Affiliates'
compliance in other respects with this Agreement. Such inspection right shall
not be exercised more than once in any calendar year nor more frequently than
once with respect to records covering any specific period of time, except in the
event of accounting changes or restatements by Novartis or its Affiliates
directly related


                                       25

to a Drug Product and limited to any specific country changes or restatements.
Avanir agrees to hold in strict confidence all information received and all
information learned in the course of any audit or inspection, except to the
extent necessary for such Avanir to reveal such information in order to enforce
its rights under this Agreement or if disclosure is required by law, regulation
or judicial order.

     (c) [***] shall pay for such inspections, as well as its own legal expenses
associated with enforcing its rights with respect to any payments hereunder,
except that in the event there is any upward adjustment in aggregate amounts
payable for any year shown by such inspection of more than [***] percent
([***]%) of the amount paid, [***] shall pay for such inspection.

     8.2 AVANIR INTELLECTUAL PROPERTY

     (a) All Avanir Intellectual Property whether or not patentable, will be the
property of Avanir, and Avanir shall be the sole owner of such Avanir
Intellectual Property.

     (b) Avanir shall be responsible for, and Novartis shall bear all reasonable
expenses incurred in, preparing, filing, prosecuting and maintaining the Avanir
Patents. For the purposes of this Section 8.2, Novartis shall only bear such
expenses in the event that: (i) in the case of a new patent application, the
Parties have agreed upon the filing of such new patent application and its
scope; (ii) the Parties have agreed, before filing, upon any country variant in
case of any foreign filing which is due during the term of this Agreement; (iii)
in the case of payments to patent agents employed by Avanir or its Affiliates,
Novartis has received the current fee sheet for such patent agent; and (iv)
Avanir has informed Novartis promptly upon becoming aware of any extraordinary
costs to be spent in patent prosecution or patent maintenance in any country,
including but not limited to costs in appeal proceedings, opposition
proceedings, costs for the filing of divisional applications, claim fees, and
the like, and Novartis has agreed to pay such costs in advance, which agreement
shall not be unreasonably withheld or delayed.

     (c) Novartis and its Affiliates undertake at the reasonable request of
Avanir to sign, or have signed, any and all documents necessary in connection
with the filing, prosecution, maintenance, extension and enforcement of the
Avanir Patents and to take such other necessary actions as Avanir may reasonably
request from Novartis or its Affiliates in connection with the Avanir Patents.

     (d) Avanir shall keep Novartis apprised of any activities related to the
Avanir Patent Rights by providing Novartis: (i) with a draft of new applications
and foreign filing texts at least ten (10) business days before the intended
filing; (ii) promptly with copies of all official actions, amendments and
responses, which affect the scope of any claims; (iii) with foreseen amendments
and responses to official actions which affect the scope of any claim at least
five (5) business days before the action due date. Avanir shall take into

equivalent, and the corresponding Patent status (pending, granted, opposed,
under appeal, (un)intentionally abandoned, etc.). Additionally, Avanir shall
notify Novartis of any new Patent applications comprising Avanir Intellectual
Property filed in any country promptly after such Patent application is filed.

     8.3 JOINT INTELLECTUAL PROPERTY

     (a) Joint Intellectual Property and all Patents claiming joint inventions
shall be owned jointly by Novartis and Avanir, and such Patents shall constitute
"Joint Patents". Joint inventorship shall be determined in accordance with the
rules of inventorship under the patent laws of the United States.

     (b) The Parties shall determine by mutual agreement which Party shall be
responsible for the filing, prosecution and maintenance of Joint Patents on a
case-by-case basis.

     (c) In the event that a Party responsible for the filing, prosecution and
maintenance of any patent filing within Joint Patents (the "responsible Party")
desires to abandon such patent filing, or if the responsible Party declines
responsibility for such patent filing, the responsible Party shall notify
promptly the other Party (and in any event not less than sixty (60) calendar
days prior to the deadline for taking appropriate action with respect to such
Joint Patent). If the other Party believes that the Joint Patent in question
should be filed, prosecuted and/or maintained, it shall inform the responsible
Party of its belief and the Parties will negotiate in good faith to find a
mutually acceptable course of action.

     (d) Novartis shall bear all reasonable expenses incurred in preparing,
filing, prosecuting and maintaining the Joint Patents. In the event that Avanir
has been determined to be the Party responsible for the filing, prosecution and

and its scope; (ii) in the case of a foreign filing decision the Parties have
agreed upon any country variant in case of any foreign filing which is due
during the term of this Agreement; (iii) in the case of payments to patent
agents employed by Avanir or its Affiliates, Novartis has received the current
fee sheet for such patent agent; and (iv) in the case of extraordinary costs

costs to be spent in patent prosecution or patent maintenance in any country,
including but not limited to costs in appeal proceedings, opposition
proceedings,


                                       28

costs for the filing of divisional applications, claim fees, and the like and
Novartis has agreed to pay such costs in advance, which agreement shall not be
unreasonably withheld or delayed.

     8.4 INFRINGEMENT

     (a) If either Party becomes aware of any activity that such Party believes
represents an infringement of the claims of the Avanir Intellectual Property or
the Novartis Intellectual Property, the Party obtaining such knowledge shall
promptly advise the other in writing of all relevant facts and circumstances
pertaining to the potential infringement. Novartis and Avanir shall thereafter
consult and cooperate fully to determine a course of action, including but not
limited to, the commencement of legal action to terminate any infringement of
the Avanir Intellectual Property or the Novartis Intellectual Property.

     (b) Novartis or its Affiliates shall have the first right, but not
obligation, to initiate and prosecute such legal proceedings related to Novartis
Intellectual Property, and Avanir shall have the first right, but not
obligation, to initiate and prosecute such legal proceedings related to Avanir
Intellectual Property, each at its own expense and in its own name, and to
control the defense of any declaratory judgment action relating to its
Intellectual Property; provided that no settlement shall be entered into by such
Party without the written consent of the other Party if such settlement would
materially affect the other Party's interests. Each Party shall cooperate with
the other Party in such effort, including being joined as a party to such action
if necessary.

     (c) If the Party which is entitled to firstly pursue the defense, does not
succeed, within ninety (90) calendar days after receiving notice from the other
Party of a potential infringement or within sixty (60) calendar days after
providing the other Party with notice of such infringement, either: (i) in
terminating such infringement; or (ii) in instituting an action to prevent
continuation thereof, or if the Party notifies the other Party that it does not
plan to defend against or terminate the infringement or to institute any such
action, then the other Party shall have the right to do so at its own cost and
expense. Each Party shall cooperate with the other Party in such effort,
including being joined as a party to such action if necessary.

     (d) In addition, each Party shall have the right to join in any action
against infringement brought in accordance with this Section 8.4 if necessary in
order to assert the damages incurred by such Party as a result of the alleged
infringement; provided that: (i) the


                                       29

foregoing shall not limit or restrict in any way the rights of the Party
controlling such action as determined in accordance with this Section 8.4 from
exercising such control in its discretion; (ii) in the event Avanir joins
Novartis in the defense of an infringement action, Avanir may elect to
participate up to [***] percent ([***]%) of the total out-of-pocket cost and
expense of Novartis and Avanir and consequently share to the same proportion in
any award; and (iii) in the event Novartis joins Avanir in the defense of an
infringement action, Novartis may elect to participate up to [***] percent
([***]%) of the total out-of-pocket cost and expense of Novartis and Avanir and
consequently share to the same proportion in any award. In the event that Avanir
decides not to join Novartis by way of participating in paying for out-of-pocket
costs and expenses, any recovery by Novartis (after reimbursement of its
out-of-pocket costs and expenses), which is intended as a reimbursement for
[***] as a result of such infringement shall be treated as [***] for purposes of
this Agreement. If Avanir pursues any such matter after Novartis declines to do
so, any recovery shall belong to Avanir alone.

     (e) The costs and expenses (including attorneys' fees) of any action
against an infringement brought in accordance with this Section shall be borne
by the Party controlling the infringement action, unless stated otherwise in
this Article VIII.

     8.5 UPDATING

     Each Party shall keep the other reasonably informed of developments in any
action or proceeding relating to the potential infringement of the claims of a
Patent relating to the Compounds or the Drug Products including, to the extent
permissible by law, the state of any settlement negotiations and the terms of
any offer related thereto.

     8.6 DEFENSE AND SETTLEMENT OF THIRD PARTY CLAIMS

     (a) If a Third Party asserts that a patent, trademark or other intellectual
properties owned by it is infringed by the importation, manufacture, use or sale
of any Compound or Drug Product, or if either Party learns of a claim or
assertion that the development, manufacture, use, marketing, promotion,
importation, exportation, offer for sale, sale or distribution of the Compounds
or the Drug Products infringes or otherwise violates the intellectual property
rights of any Third Party, then such Party will promptly notify the other Party
in writing. Novartis will have the sole right, but not the obligation, to
control such defense at its own expense. If Novartis does not assume control of
such defense, then Avanir shall have the right to control such defense at its
own expense. In any event, the

                                              * Confidential Treatment Requested


                                       30

Party not controlling such defense will have the right to be represented in any
such action at its own expense. The Party controlling such defense shall keep
the other Party advised of the status of such action and shall consider
recommendations made by the other Party in respect thereto. The Party not
controlling such defense will assist and cooperate in any such infringement
litigation at the defending Party's reasonable request. If the Party controlling
such defense is not the Party against whom such action was originally brought,
then the Party controlling such defense will not agree to the settlement of any
such action without the prior written consent of the other Party.

     (b) If Novartis conducts the defense, Novartis will use Commercially
Reasonable Efforts to determine how and whether to defend against such charge of
infringement.

     (c) During the period in which such litigation is pending and following the
resolution thereof, Novartis shall bear all other costs incurred in connection
therewith (including litigation costs, attorneys fees, costs of settlement)
including damage awards and any other payment resulting therefrom in the event
Novartis is barred as a result of such litigation from further sales in the
country concerned.

     (d) Such application and deduction shall not apply to infringement caused
by Novartis' or its Affiliates' use of their respective name, trade name, logo
or the Novartis Patents or Novartis Know-How.

     8.7 TRADEMARKS

     Novartis or its Affiliates will be responsible for, and shall have sole
discretion in, selecting trademarks for the use on or in connection with the
Drug Products in the Territory. Novartis or its Affiliates will be responsible
for registration of such trademarks and will be the sole owner of such
trademarks. For the avoidance of doubt, trademarks, including those created
hereunder, are not included in the definition of Know-How.

     8.8 DRUG PRICE COMPETITION AND PATENT TERM RESTORATION ACT AND PEDIATRIC
EXCLUSIVITY

     (a) The Parties shall cooperate in an effort to avoid the loss of any
rights which may otherwise be available to the Parties under the provisions of
the Drug Price Competition and Patent Term Restoration Act of 1984 or comparable
laws outside of the United States and for pediatric exclusivity.


                                       31

to any relevant Drug Master Files and pre-clinical, clinical or regulatory

restoration or supplemental protection certificates or their equivalents in any
country and region in the Territory where applicable. Avanir shall provide all
reasonable assistance to Novartis and its Affiliates, including permitting
Novartis or its Affiliates to proceed with applications for such in the name of
Avanir, if so required.

     11.2 DISPUTE RESOLUTION PROCESS

     (a) Except as otherwise explicitly provided herein, in the event of any
claim arising out of or relating to any provision of this Agreement, failing
resolution of the controversy or claim, the matter shall be referred to the
chief executive officer of Avanir or his designee and the chief executive
officer of Novartis or his designee who shall, as soon as practicable, attempt

     (b) In the event of any controversy or claim arising out of or relating to
any provision of this Agreement, the Parties shall try to settle their
differences amicably between themselves. Any unresolved disputes arising between
the Parties relating to, arising out of or in any way connected with this

Party arbitrator, and the Party-arbitrators shall select, if available, a
neutral arbitrator who shall have significant senior management experience in
the pharmaceutical or biotechnology businesses to be chairman of the arbitration
panel, within thirty (30) calendar days thereafter. If the Party-arbitrators are
unable to select a neutral arbitrator within such period, the neutral arbitrator
shall be appointed in accordance with ICC rules. All arbitrator(s) eligible to
conduct the arbitration must agree to render their opinion(s) within thirty (30)
calendar days of the final arbitration hearing. No arbitrator (nor the panel of
arbitrators) shall have the power to award punitive damages under this Agreement
and such award is expressly prohibited. Decisions of the arbitrator(s) shall be
final and binding on all of the Parties. Judgment on the award so rendered may
be entered in a court having jurisdiction thereof. In any arbitration pursuant
to this Agreement, the arbitrators shall


                                       37

interpret the express terms hereof and apply the laws of the State of Delaware.
The losing Party to the arbitration (if any) as determined by the arbitrators
shall pay the costs of arbitration. Notwithstanding the provisions of this
Section 11.2(b), either Party may seek preliminary or injunctive measures or
other equitable relief in any court of competent jurisdiction.

shall include those rights afforded by 11 U.S.C. Section 365(n) of the United
States Bankruptcy Code (the "USBC") and any successor thereto. If the bankruptcy
trustee of a Bankrupt Party as a debtor or debtor-in-possession rejects this
Agreement under 11 U.S.C. Section 365(o) of the USBC, the non-Bankrupt Party may
elect to retain its rights licensed from the Bankrupt Party hereunder (and any
other supplementary agreements hereto) for the duration of this Agreement and
avail itself of all rights and remedies to the full extent contemplated by this
Agreement and 11 U.S.C. Section 365(n) of the USBC, and any other relevant laws.

     12.4 TERMINATION BY NOVARTIS

     Following the [***] anniversary of the Effective Date, Novartis may
terminate this Agreement at any time upon the provision of sixty (60) calendar
days' prior written notice. In addition, Novartis may, in its sole discretion,
relinquish the licenses granted to it hereunder with respect to any particular
Compound or Drug Product without affecting the licenses granted to it hereunder
with respect to any other Compound or Drug Product. There shall be a wind-down
period (the "Wind-Down Period") of [***] subsequent to the effective termination
date during which Novartis or its Affiliates shall only continue to fund that
number of Avanir FTEs that were involved in the Research Plan immediately prior

                                              * Confidential Treatment Requested


                                       39

to the termination notice. For the avoidance of doubt, only those activities in
which Avanir had been engaged at the time of termination shall continue during
the Wind-Down Period.

     12.5 EFFECT OF TERMINATION

     (a) Termination of this Agreement for any reason, or expiration of this
Agreement, will not affect: (i) obligations, including the payment of any
royalties and milestones which have accrued as of the date of termination or
expiration; and (ii) rights and obligations which, from the context thereof, are
intended to survive termination or expiration of this Agreement.

     (b) For each country, at the end of the term of this Agreement as provided
in Section 12.1 in respect of a Drug Product, Novartis and its Affiliates shall
have a perpetual, non-exclusive, transferable, paid-up, royalty-free license
with the right to sublicense in such country, to research, develop, have
developed, make, have made, use, distribute, have distributed, export, have
exported, import, have imported, promote, have promoted, market, have marketed,
sell, have sold and offer to sell the Compounds, the Drug Product in the Field
in the Territory under the Avanir Intellectual Property.

     (c) If Novartis terminates this entire Agreement pursuant to Section 12.4
or Avanir terminates this entire Agreement pursuant to Section 12.2, then all
licenses granted to Novartis and its Affiliates hereunder shall terminate and
revert to Avanir, and any sublicenses granted by Novartis or its Affiliates
hereunder shall be assigned to Avanir, and all copies of confidential
information of Avanir shall be returned to it.

     (i)  Novartis and its Affiliates shall grant to Avanir an exclusive,
          worldwide, paid-up license under Novartis Intellectual Property (with
          the right to sublicense with the consent of Novartis, which shall not
          be unreasonably withheld or delayed) to research, develop, have
          developed, make, have made, use, distribute, have distributed, export,
          have exported, import, have imported, promote, have promoted, market,
          have marketed, sell, have sold and offer to sell the Compounds (except
          Novartis Submitted Compounds) and the Drug Products (except Submitted
          Drug Products) whether in monotherapy or in combination with other
          pharmaceutical products, in the Field in the Territory.
          Notwithstanding the foregoing, in the event that Avanir commercializes
          any such Drug Product that Novartis has progressed through Development
          to the end of [***], then Avanir shall pay to Novartis a [***] percent
          ([***]%) royalty

                                              * Confidential Treatment Requested


                                       40

          on any future sales of such Drug Product sold directly by Avanir or
          its Affiliates, and in the case where Avanir does not sell such Drug
          Product directly, Avanir shall pay to Novartis a [***] percent
          ([***]%) royalty on any future sales of such Drug Product sold
          indirectly by Avanir or its Affiliates.

     (ii) In the event that Novartis determines in its sole discretion that it
          wishes to license out, sell, or transfer rights to develop any
          Submitted Drug Product(s), Avanir shall have a first right of
          negotiation to acquire exclusive rights to such Submitted Drug
          Product(s) on commercially reasonable terms. In such event, Novartis
          shall give written notice to Avanir that it wishes to license out,
          sell, or transfer rights to develop such Submitted Drug Product(s) and
          Avanir shall have thirty (30) days from the date on which it is deemed
          pursuant to Section 16.14 to have received such notice from Novartis
          to inform Novartis in writing of whether it wishes to act on its right
          of first negotiation. If Avanir does not notify Novartis in writing of
          its desire to act on its right of first negotiation within this thirty
          (30) day period, Novartis shall be free to grant rights to such
          Submitted Drug Products(s) to Third Parties. If Avanir does notify
          Novartis in writing of its desire to act on its right of first
          negotiation within this thirty (30) day period, the Parties shall
          enter into good faith negotiations regarding the terms and conditions
          for the proposed license, sale, or transfer rights to develop such
          Submitted Drug Product(s). In the event that the Parties fail to
          conclude such good faith negotiations and execute the agreements
          documenting such transaction within one hundred and twenty (120) days
          of the date on which Avanir notifies Novartis of its desire to act on
          its right of first negotiation, Novartis shall be free grant rights to
          such Submitted Drug Products(s) to Third Parties; provided that,
          Novartis shall not license, sell, or transfer such rights to a Third
          Party on terms more favorable to such Third Party than those last
          offered to Avanir without notifying Avanir in writing and affording
          Avanir the opportunity to enter into the proposed transaction on the
          same terms and conditions. In such event, Avanir shall have ten (10)
          business days in which to notify Novartis in writing that it wishes to
          enter into such transaction on the proposed terms and conditions.

                                              * Confidential Treatment Requested


                                       41

     (iii) In the event that termination occurs during the Development but prior
          to the First Commercial Sale of a Drug Product, Avanir may elect, but
          solely for Compounds and Drug Products that originated as Avanir
          Intellectual Property, and give, within sixty (60) calendar days of
          the date of termination notice, written notice to Novartis requesting
          the transfer of Data and Know-How as it pertains to the manufacturing
          processes of the relevant Compound and/or Drug Product, and to
          purchase remaining stocks and inventory of the relevant Compound
          and/or Drug Product that Novartis may have in its possession. The
          purchase price for such stocks shall be based on direct labor and
          out-of-pocket costs that Novartis may have incurred for such stock.
          The purchase shall be EX WORKS (Incoterms 2000) with [***]. Novartis
          shall make no representations or warranties as to the suitability of
          such stocks for any use and will be sold as-is. Novartis shall not be
          obligated to conduct any further testing on such stocks. Novartis
          shall not be required to dedicate more than [***] FTEs to such efforts
          and in any case shall not be required to provide further efforts
          towards the transfer of such manufacturing Data and Know-How beyond
          ninety (90) calendar days of the actual termination date of this
          Agreement. Avanir may request and Novartis, in its sole discretion,
          may provide further assistance towards the Data and Know-How transfer,
          however such assistance by Novartis shall be reimbursed by Avanir at
          the then prevailing Novartis FTE compensation rate. The Parties shall
          also agree to transfer any Regulatory Filings regarding such Compound
          and Drug Product from Novartis to Avanir, and Avanir shall bear any
          costs that may be incurred during such transfer. In the event that
          termination occurs after the First Commercial Sale of a Drug Product
          that originated as Avanir Intellectual Property, the Parties agree to
          enter into good faith negotiations to conclude a commercially
          reasonable supply agreement which, at a minimum, will provide for
          Novartis to supply and Avanir to purchase, commercially acceptable
          Drug Product for a period of [***]. The Parties shall also agree to
          transfer affected Regulatory Filings pursuant to such Compounds and
          Drug Products from Novartis to Avanir, and Avanir shall bear any costs
          that may be incurred during such transfer.

                                       42

     (d) If Novartis terminates this entire Agreement pursuant to Section 12.2,
then Novartis and its Affiliates shall be entitled to convert the license
granted herein to an exclusive, worldwide license, with the right to sublicense,
to research, develop, have developed, make, have made, use, distribute, have
distributed, export, have exported, import, have imported, promote, have
promoted, market, have marketed, sell, have sold and offer to sell the
Compounds, the Drug Products in the Field in the Territory under the Avanir
Intellectual Property, subject only to the obligation to pay to Avanir the
amounts due under Sections 7.4 and 7.5 as they become due; provided, however, in
the event that such termination was due to (i) the purported grant to a Third
Party of license rights granted exclusively to Novartis under this Agreement,
(ii) the disclosure by Avanir of material confidential information of Novartis
in violation of Article X of this Agreement, (iii) Avanir ceasing to perform its
funded obligations during the Research Term or (iv) the material breach by
Avanir of any of the representations or warranties set out in Section 9.1,
Novartis shall only be obligated to pay to Avanir [***] percent ([***]%) of the
amounts otherwise due under Sections 7.4 and 7.5 as they become due.

                                 INDEMNIFICATION

     13.1 INDEMNIFICATION BY AVANIR

     Avanir will indemnify and hold Novartis and its Affiliates, and their
employees, officers and directors harmless against any Third Party loss,
damages, action, suit, claim, demand, liability, expense, bodily injury, death
or property damage (a "Loss"), that may be brought, instituted or arise against
or be incurred by such Persons to the extent such Loss is based on or arises out
of:

     (a) negligence or willful misconduct concerning the Research Program, a
Compound or a Drug Product by Avanir or its Affiliates; or

     (b) the breach by Avanir of any of its material obligations, covenants,
representations or warranties set forth in this Agreement; and

     (c) provided that the foregoing indemnification shall not apply to any Loss
to the extent such Loss is caused by the breach of this Agreement, negligent or
willful misconduct of Novartis or its Affiliates and their employees, officers
and directors.

     Novartis will indemnify and hold Avanir, and its Affiliates, and their
employees, officers and directors harmless against any Third Party Loss that may
be brought, instituted or arise against or be incurred by such Persons to the
extent such Loss is based on or arises out of:

     (a) the development, manufacture, use, sale, storage or handling of a
Compound or a Drug Product by Novartis or its Affiliates or their
representatives, agents, licensees, sublicensees or subcontractors under this
Agreement, or any actual or alleged violation of law resulting therefrom (with
the exception of Losses based on infringement or misappropriation of
intellectual property rights); or

     (b) the breach by Novartis of any of its material obligations, covenants,
representations or warranties set forth in this Agreement;

     (c) the breach by any of Novartis' or its Affiliates or sublicensees of any

to the extent such Loss is caused by the breach of this Agreement, negligent or
willful misconduct of Avanir or its Affiliates and their employees, officers and
directors.

     13.3 CLAIMS PROCEDURES

     Each Party entitled to be indemnified by the other Party (an "Indemnified
Party") pursuant to Section 13.1 or 13.2 shall give notice to the other Party
(an "Indemnifying Party") promptly after such Indemnified Party has actual
knowledge of any threatened or asserted claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided:

     (a) that counsel for the Indemnifying Party, who shall conduct the defense
of such claim or any litigation resulting therefrom, shall be approved by the
Indemnified Party (whose approval shall not unreasonably be withheld or delayed)
and the Indemnified Party may participate in such defense at such Party's
expense (unless: (i) the employment of counsel by such Indemnified Party has
been authorized by the Indemnifying Party; or (ii) the Indemnified Party shall
have reasonably concluded that there may be a conflict of interest between the
Indemnifying Party and the Indemnified Party in the defense of such action, in


                                       44

each of which cases the Indemnifying Party shall pay the reasonable fees and
expenses of one law firm serving as counsel for the Indemnified Party, which law
firm shall be subject to approval, not to be unreasonably withheld, by the
Indemnifying Party); and

     (b) the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Agreement
to the extent that the failure to give notice did not result in harm to the
Indemnifying Party.

     (c) No Indemnifying Party, in the defense of any such claim or litigation,
shall, except with the approval of each Indemnified Party which approval shall
not be unreasonably withheld, consent to entry of any judgment or enter into any
settlement which: (i) would result in injunctive or other relief being imposed
against the Indemnified Party; or (ii) does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect to such claim or litigation.

     (d) Each Indemnified Party shall furnish such information regarding itself
or the claim in question as an Indemnifying Party may reasonably request in
writing and shall be reasonably required in connection with the defense of such
claim and litigation resulting therefrom.

     13.4 LIMITATION OF LIABILITY

     Neither Party shall be liable to the other for consequential, indirect or
punitive damages. For the avoidance of doubt, no Party can recover from the
other Party more than once for a single cause of action under an indemnity
granted by an indemnifying Party pursuant to this Agreement. The foregoing
sentence shall not be construed to preclude recovery in respect of multiple
claims arising from a single event or series of events. Neither Party shall have
liability with respect to any breach of any of the other Party's representations
and warranties under this Agreement: (a) for any individual item where the Loss
relating thereto is less than $[***]; and (b) in respect of each individual item
where the Loss relating thereto is equal to or greater than $[***], unless and
until the aggregate amount of such Losses exceeds [***] percent ([***]%) of the
amounts which Novartis or its Affiliates has paid under this Agreement and then
the liable Party shall be liable for the entire amount of the Losses described
in this Article XIII. The foregoing shall not be construed to limit liability
pursuant to Section 13.1 or Section 13.2. Each Party shall take and shall cause
its Affiliates to take all reasonable steps to mitigate any Loss upon becoming
aware of any event which would reasonably be expected to, or does, give rise
thereto,

                                       45

including incurring costs only to the minimum extent necessary to remedy a
breach that gives rise to the Loss.

     13.5 COMPLIANCE

     The Parties shall comply fully with all applicable laws and regulations in
connection with their respective activities under this Agreement.

     13.6 INSURANCE

     Each Party shall use all commercially reasonable efforts to maintain
insurance and/or self-insurance including product liability insurance, with
respect to its activities hereunder and, in that event, shall claim upon such

                                  PIRATE GOODS

     Novartis and its Affiliates shall exercise commercially reasonable efforts
to monitor the sales in the Territory and take action to prevent trade in goods
by a Third Party that violate Novartis' or its Affiliates' exclusive legal
rights to market, price and sell a Drug Product in such a market. In the event
that Avanir first becomes aware of such a trade in goods by a Third Party which
violates Novartis' or its Affiliates' exclusive legal rights, Avanir shall
notify Novartis within seven (7) calendar days of first becoming aware of such
trading by a Third Party.

                                   ARTICLE XV

                                   EXCLUSIVITY

communications between the Parties hereto shall be conducted in that language.

     16.2 EXPORT CONTROLS

     This Agreement is made subject to any restrictions concerning the export of
materials and intellectual property from the United States which may be imposed
upon or related to either Party to this Agreement from time to time by the
Government of the United States. Furthermore, Novartis and its Affiliates will
not export, directly or indirectly, any Avanir Intellectual Property or any
Compound or Drug Product utilizing such Avanir Intellectual Property to any
countries for which the United States Government or any agency thereof at the
time of export requires an export license or other governmental approval,
without first obtaining the written consent to do so from the Department of
Commerce or other agency of the United States Government when required by
applicable statute or regulation.

     16.3 PHARMACOVIGILANCE

     Novartis shall be fully responsible for ensuring compliance with all
pharmacovigilance obligations, including the holding and maintaining of the

Approval of the first Drug Product, the Parties shall agree and implement a
procedure for the mutual exchange of adverse event reports and safety
information associated with the Drug Product. Details of the operating procedure
respecting such adverse event reports and safety information exchange shall be
the subject of a mutually acceptable pharmacovigilance agreement between the
Parties which shall at that time be made an addendum to this Agreement. Such
pharmacovigilance agreement shall be implemented at a time sufficient to permit
compliance with applicable guidelines and regulations of regulatory authorities.

     16.4 WAIVER

     No provision of the Agreement may be waived except in writing by both
Parties hereto. No failure or delay by either Party hereto in exercising any
right or remedy hereunder or under applicable law will operate as a waiver
thereof, or a waiver of a particular right or waiver of any right or remedy on
any subsequent occasion.

     16.5 FORCE MAJEURE

     Neither Party shall be held liable or responsible to the other Party nor be
deemed to have defaulted under or breached this Agreement for failure or delay
in fulfilling or performing any term of this Agreement, other than an obligation
to make a payment, when such failure or delay is caused by or results from fire,
floods, embargoes, government regulations, prohibitions or interventions, war,
acts of war (whether war be declared or not), insurrections, riots, civil
commotions, strikes, lockouts, acts of God, or any other cause beyond the
reasonable control of the affected Party.

     16.6 REGISTRATION OF LICENSE

     Novartis or its Affiliates may, at its or their expense, register the
license granted under this Agreement in any country where the use, sale or
manufacture of a Drug Product in such country would be covered by a Valid Claim.
Upon request by Novartis or its Affiliates, Avanir agrees promptly to execute
any "short form" licenses submitted to it by Novartis or its Affiliates in order
to effect the foregoing registration in such country, but such licenses shall in
no way alter or affect the obligations of the Parties hereunder.

     16.7 SEVERABILITY

     It is the intention of the Parties to comply with all applicable laws
domestic or foreign in connection with the performance of its obligations
hereunder. In the event that any provision of this Agreement, or any part
hereof, is found invalid or unenforceable, the remainder of this Agreement will
be binding on the Parties hereto, and will be construed as if the invalid or
unenforceable provision or part thereof had been deleted, and the Agreement
shall be deemed modified to the extent necessary to render the surviving
provisions enforceable to the fullest extent permitted by law.

     16.8 GOVERNMENT ACTS

     In the event that any act, regulation, directive, or law of a government,
including its departments, agencies or courts, should make impossible or
prohibit, restrain, modify or limit any material act or obligation of Novartis,
Avanir and their respective Affiliates under this Agreement, the Party, if any,
not so affected shall have the right, at its option, to suspend or terminate
this Agreement as to such country, if good faith negotiations between the
Parties to make such modifications to this Agreement as may be necessary to
fairly address the impact thereof, are not successful after a reasonable period
of time in producing mutually acceptable modifications to this Agreement.

     16.9 GOVERNMENT APPROVALS


                                       48

     Novartis will use reasonable efforts to obtain any government approval
required to enable this Agreement to become effective, or to enable any payment
hereunder to be made, or any other obligation hereunder to be observed or
performed. Each Party will keep the other informed of progress in obtaining any
such approvals.

     16.10 ASSIGNMENT

     Novartis may assign its rights and obligations under this Agreement without
the prior written consent of Avanir to an Affiliate or in connection with the
transfer or sale of all or substantially all of its assets or business or in the
event of its merger or consolidation with a Third Party. Novartis may also
assign its rights and obligations under this Agreement to any of the [***], with
the prior written consent of Avanir. Avanir may not assign its rights and
obligations under this Agreement during the Research Term without the prior
written consent of Novartis. Thereafter, but prior to receipt of the first
Regulatory Approval for a Drug Product, Avanir may assign its right to receive
payments under this Agreement only to a Third Party which has a market
capitalization prior to the assignment (including its affiliates) of less than
$[***]. Following the receipt of the first Regulatory Approval for a Drug
Product, Avanir may assign its right to receive payments under this Agreement
without the prior written consent of Novartis. Any other proposed assignment by
Avanir of its rights and obligations under this Agreement shall require the
prior written consent of Novartis. Any request for consent to assignment shall
not be unreasonably withheld or delayed. In addition, Avanir shall be entitled
to assign all or any part of its right to receive payments under this Agreement.
Any purported assignment in contravention of this Section 16.10 shall, at the
option of the non-assigning Party, be null and void and of no effect. No
assignment shall release either Party from responsibility for the performance of
any accrued obligation of such Party hereunder. This Agreement shall be binding
upon and enforceable against the successor to or any permitted assignee from
either of the Parties hereto.

     16.11 AFFILIATES

     Each Party may perform its obligations hereunder personally or through one
or more Affiliates, although each Party shall nonetheless be solely responsible
for the performance of its Affiliates. Neither Party shall permit any of its
Affiliates to commit any act (including any act of omission) which such Party is
prohibited hereunder from committing directly. The use of subcontractors by
either Party shall not increase the financial obligations of the other Party
hereunder in any respect.

     Nothing herein contained shall be deemed to create an agency, joint
venture, amalgamation, partnership or similar relationship between Novartis and
Avanir. Notwithstanding any of the provisions of this Agreement, neither Party
shall at any time enter into, incur, or hold itself out to third Parties as

commitment, expense, or liability whatsoever, and all contracts, expenses and
liabilities undertaken or incurred by one Party in connection with or relating
