Dear Stephen:

 

In connection with the sale by Cambridge Laboratories (Ireland) Limited
(“Cambridge”) of its worldwide rights in and to tetrabenazine and related assets
(the “TBZ Business”) to Biovail Laboratories International (Barbados) SRL
(“Biovail”) (the “Transaction”), we are writing to confirm our understanding on
certain points relating to the TBZ Business.

 

Reference is made to the Licence Agreement between LifeHealth Limited
(“Lifehealth”) and Cambridge, dated December 10, 1998 (the “1998 Lifehealth
Licence”), as amended by Amendment No. 1, dated 29 October 2002, Amendment
No. 2, dated 31 March 2004, and Amendment No. 3, dated 12 August 2004
(collectively, the “1998  Lifehealth Licence Amendments”, and the 1998
Lifehealth Licence, as amended by the 1998 Lifehealth Licence Amendments, is
referred to as the “1998 Amended Lifehealth Licence”), and the Licence and
Consent Agreement between Cambridge and Lifehealth, dated September 22, 2006
(the “2006 Lifehealth Licence”, and, the 2006 Lifehealth Licence together with
the 1998 Amended Lifehealth Licence is referred to as the “LifeHealth
Agreements”). Capitalized terms used but not otherwise defined herein shall have
the meanings attributed to them in the LifeHealth Agreements.

 

We confirm our commitment to proceed with the development of a second indication
for the controlled release formulation of tetrabenazine (the “CR Formulation”),
subject to our determination, after satisfactory due diligence, that it is
commercially and clinically reasonable to so proceed. The exact indication to be
developed will be determined by agreement between Lifehealth and Biovail, after
further review and consideration, and may include tardive dyskinesia, dystonia
or some other indication. We also confirm that, conditional on the closing of
the Transaction, the costs associated with the development of the CR
Formulation, as between Lifehealth and Biovail, shall be shared as follows:

 

·                                          Development costs associated with the
CR Formulation for Tourette Syndrome will be shared by Lifehealth and Biovail
(in the manner contemplated by the LifeHealth Agreements);

 

--------------------------------------------------------------------------------

 

·                                          Biovail will be responsible for
{***}† associated with the clinical development in the United States of the
second indication of the CR Formulation and such costs will not be {***}† Total
Net Receipts for the purposes of calculating {***}†;

 

·                                          Lifehealth and Biovail will share the
costs associated with the galenical development in the United States of the
second indication of the CR Formulation (in the manner contemplated by the
LifeHealth Agreements); and

 

·                                          As regards the development and
regulatory costs associated with the exploitation of the second indication of
the CR Formulation in jurisdictions outside of the United States, Lifehealth and
Biovail will share all such costs (in the manner contemplated by the LifeHealth
Agreements).

 

We also wish to confirm to you our commitment to growing the TBZ Business on a
worldwide basis. In that regard, and without prejudice to the provisions of
clause 9.4 of the 1998 Lifehealth Licence, Biovail agrees to use commercially
reasonable efforts to exploit tetrabenazine in jurisdictions outside of the
United States, subject to our reasonable determination that such activities are
commercially reasonable on a market by market basis.

 

Yours sincerely,

 

 

 

/s/ MICHEL CHOUINARD
