LETTERHEAD] February 26, 1998 SciClone Pharmaceuticals Inc. 901 Mariner's Island Blvd. San Mateo California 94404 USA Dear Sirs, RE: THYMOSIN ALPHA 1 This letter is a follow-up of the discussions held between you ("SciClone") and us ("Sigma-Tau") regarding the product Thymosin Alpha 1 (hereinafter "Product"). Sigma-Tau is the holder of a health registration (so called "Autorizzazione all'Immissione in Commercio") of the Product in Italy. Such health registration has been obtained by Sigma-Tau through grant of rights from Sclavo SpA. SciClone is now under negotiations with Sclavo SpA for the acquisition of the rights relating to Product in Italy. Sigma-Tau requires further information regarding the Product in order to renew such health registration with the Italian Ministry of Health in Italy. Following execution of this letter, SciClone shall, in good faith, attempt to have Sclavo SpA disclose to Sigma-Tau all information necessary and sufficient to renew and maintain the health registration of the Product (hereinafter "Information") in Italy. The Information shall be used by Sigma-Tau solely for the purpose of filing it with the Italian Ministry of Health in order to renew and maintain the health registration of the Product in the name of Sigma-Tau and for no other purpose whatsoever. Further, Sigma-Tau undertakes not to use the health registration so renewed for any purpose until an agreement between Sigma-Tau and SciClone for the distribution in Italy of the Product has been executed, provided that SciClone acquires the rights on the Product in Italy. Save for disclosure to the Italian Ministry of Health as provided for in this letter, Sigma-Tau shall ensure that the Information is not disclosed to any third party without the prior written consent of SciClone for a period of ten (10) years from receiving of such Information, unless such provision is superseded by further agreements executed between the parties hereof. This undertaking shall not apply to any part of the Information which: (a) become generally available to the public other than as a result of disclosure by Sigma-Tau or any party to whom Sigma-Tau has disclosed such Information to; or 44 45 (b) Sigma-Tau can demonstrate was in its possession at the time of disclosure to it by SciClone and which Sigma-Tau lawfully acquired other than from SciClone or anyone acting on its behalf; or (c) was lawfully acquired on a non-confidential basis from others who are not prohibited from disclosing such Information by an obligation to SciClone; or (d) was disclosed with the prior approval of SciClone. Notwithstanding anything in this letter to the contrary, it does not in any way constitute an obligation or undertaking by Sigma-Tau or by SciClone to enter into any agreement relating to the distribution in Italy of the Product or otherwise. If the foregoing is acceptable to you, will you please sign the attached copy of this letter and return said signed copy to us.
