 EXECUTION COPY 
 TRADEMARK SECURITY AGREEMENT 
 (SHORT-FORM) 
 TRADEMARK SECURITY AGREEMENT (this “Agreement”), dated
as of February 25, 2008 between AXCAN PHARMA US, INC. (the “Grantor”) and BANK OF AMERICA, N.A., as administrative agent for the Secured Parties. 
 Reference is made to the Pledge and Security Agreement dated as of February 25, 2008 (as amended, supplemented or otherwise modified from time to time, the “Security Agreement”), among Holdings,
the Parent Borrower, the Co-Borrower, certain other Subsidiaries of the Parent Borrower from time to time party thereto and the Administrative Agent. The Secured Parties’ agreements in respect of extensions of credit to the Borrowers are set
forth in (i) the Credit Agreement dated as of February 25, 2008 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Parent Borrower, the Co-Borrower, Holdings, Bank of
America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, and each lender from time to time party thereto and (ii) the Senior Secured Notes Indenture. The Grantor is an affiliate of the Borrowers and will derive substantial
benefits from the extension of credit to and the purchase of notes from the Borrowers pursuant to the Credit Agreement and the Senior Secured Notes Indenture, and is willing to execute and deliver this Agreement in order to induce the Lenders and
the purchasers to extend such credit and provide such debt financing. Accordingly, the parties hereto agree as follows: 
 Section 1.
Terms. Capitalized terms used in this Agreement and not otherwise defined herein have the meanings specified in the Security Agreement. The rules of construction specified in Article 1 of the Credit Agreement also apply to this Agreement.

 Section 2. Grant of Security Interest. As security for the payment or performance, as the case may be, in full of the Secured
Obligations, the Grantor, pursuant to and in accordance with the Security Agreement, did and hereby does grant to the Administrative Agent, its successors and assigns, for the benefit of the Secured Parties, a security interest in, all right, title
and interest in or to any and all of the following assets and properties now owned or at any time hereafter acquired by the Grantor or in which the Grantor now has or at any time in the future may acquire any right, title or interest (collectively,
the “Trademark Collateral”): 
 (a) all trademarks, service marks, trade names, corporate names, trade dress, logos,
designs, fictitious business names, other source or business identifiers, now existing or hereafter adopted or acquired, all registrations and recordings thereof, and all registration and recording applications filed in connection therewith,
including registrations and registration applications in the 








 
USPTO, and all extensions or renewals thereof, as well as any unregistered trademarks and service marks used by the Grantor, including those listed on
Schedule I hereto; and 
 (b) all goodwill connected with the use thereof and symbolized thereby (provided that no security interest shall be
granted in the United States intent-to- use trademark applications to the extent that, and solely during the period in which, the grant of a security interest therein would impair the validity or enforceability of such intent-to-use trademark
applications under applicable federal law). 
 Section 3. Termination. This Agreement is made to secure the satisfactory
performance and payment of the Secured Obligations. The security interest granted hereby shall terminate under the conditions and to the same extent set forth in Section 6.12 of the Security Agreement. The Administrative Agent shall, in
connection with any termination or release herein or under the Security Agreement, execute and deliver to the Grantor as the Grantor may request, an instrument in writing effecting or evidencing such termination or release with respect to the
Trademark Collateral acquired under this Agreement. Additionally, upon such satisfactory performance or payment, the Administrative Agent shall reasonably cooperate with any efforts made by the Grantor to make of record or otherwise confirm such
satisfaction including, but not limited to, the release and/or termination of this Agreement and any security interest in, to or under the Trademark Collateral. 
 Section 4. Supplement to the Security Agreement. The security interests granted to the Administrative Agent herein are granted in furtherance, and not in limitation of, the security interests granted to
the Administrative Agent pursuant to the Security Agreement. The Grantor hereby acknowledges and affirms that the rights and remedies of the Administrative Agent with respect to the Trademark Collateral are more fully set forth in the Security
Agreement, the terms and provisions of which are hereby incorporated herein by reference as if fully set forth herein. In the event of any conflict between the terms of this Agreement and the Security Agreement, the terms of the Security Agreement
shall govern. 
 Section 5. [Reserved.] 
 Section 6. Miscellaneous. The provisions of Article 6 of the Security Agreement are hereby incorporated by reference.
