LICENSE AND COLLABORATION AGREEMENT

THIS LICENSE AND COLLABORATION AGREEMENT (hereinafter “Agreement”) is effective as of May 7, 2014 (the “Effective Date”) by and between Piramal Imaging Ltd., incorporated under the Laws of England and Wales, having its principal place of business at 23, Science Park, Cambridge-CB4 0EY, United Kingdom (hereinafter “Piramal Imaging Ltd”), and its parent company, Piramal Imaging SA, incorporated under the laws of Switzerland, having its principal place of business at Route de l’Ecole, c/o Pascal Nguyen, 1753 Matran, Switzerland (hereinafter “Piramal Imaging SA”) (Piramal Imaging Ltd and Piramal Imaging SA hereinafter together referred to as “Piramal”), and AC Immune SA, incorporated under the laws of Switzerland, having its principal place of business at EPFL Innovation Park, Building B, 1015 Lausanne, Switzerland (hereinafter “AC Immune”) (each AC Immune and Piramal hereinafter referred to individually as a “Party” and jointly as the “Parties”).

WHEREAS, AC Immune is a leader in the discovery and development of novel therapeutics for the treatment and diagnosis of Alzheimer’s disease (“AD”) and has discovered using its Morphomer™ chemistry platform and is developing certain potential therapeutic and diagnostic compounds targeting proteins implicated in the pathology of AD, including Tau protein.

WHEREAS, AC Immune has identified a series of compounds that bind selectively to Tau protein; and one or more of such compounds may, if modified to include a radioactive isotope, be useful as a positron emission tomography (“PET”) imaging agent that would bind selectively to Tau protein and aid the detection and monitoring of AD and other neurodegenerative diseases.

WHEREAS, Piramal Imaging SA is an innovator in the discovery, development and commercialization of novel imaging agents for molecular imaging, including PET neuroimaging agents that bind selectively to a protein.

WHEREAS, Piramal Imaging SA is interested in collaborating with AC Immune to evaluate and develop certain of AC Immune’s Tau protein selective compounds as a PET imaging agent that binds selectively to Tau protein for detection and monitoring of Tau protein in patients with AD and other neurodegenerative diseases.

WHEREAS, if such development efforts are successful, Piramal Imaging Ltd, under license from Piramal Imaging SA, wishes to manufacture and commercialize a Tau protein selective PET imaging agent as a diagnostic commercial product, including for use in [*****] pharmaceutical or biotechnology companies’ clinical trials for potential therapeutic products directed to AD and other diseases where Tau protein has been implicated.

NOW THEREFORE, in consideration of the mutual covenants and agreements provided herein below and other consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows:

11.2 Termination.

(a) Breach. Either Party may terminate the Agreement, in its entirety or on a country by country basis, at any time upon an uncured material default of the other Party in the fulfillment of its obligations under or in connection with this Agreement by giving written notice to the other Party specifying the nature of the default not less than [*****] days prior to the date the non-defaulting Party intends to terminate the Agreement.

15.10 Waiver. No provision of the Agreement shall be waived by any act, omission or knowledge of a Party or its agents or employees except by an instrument in writing expressly waiving such provision and signed by a duly authorized officer of the waiving Party. The waiver by any of the Parties of any breach of any provision hereof by another Party shall not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself.

15.11 Severability. lf any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same shall not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement shall be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement shall be construed as if such clause of portion thereof had never been contained in this Agreement, and there shall be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by applicable Law.

15.12 Relationship of the Parties. The Parties agree that the relationship of Piramal and AC Immune established by this Agreement is that of independent contractors. Furthermore, the Parties agree that this Agreement does not, is not intended to, and shall not be construed to, establish an employment, agency, partnership or any other relationship. Except as may be specifically provided herein, no Party shall have any right, power or authority, nor shall they represent themselves as having any authority to assume, create or incur any expense, liability or obligation, express or implied, on behalf of any other Party, or otherwise act as an agent for any other Party for any purpose.

15.13 Interpretation. The captions and headings to this Agreement are for convenience only, and are to be of no force or effect in construing or interpreting any of the provisions of this Agreement. Unless specified to the contrary, references to Articles, Sections, Exhibits or Appendices shall refer to the particular Articles, Sections, Exhibits or Appendices of or to this Agreement and references to this Agreement include all Exhibits and Appendices hereto.
