In the case of a conversion to non-exclusivity, the royalties payable under this Agreement, as determined in accordance with Section 5.5, shall be reduced by [***] and Cerulean shall grant to Calando a non-exclusive, transferable (as permitted pursuant to Section 13.1), irrevocable and perpetual, royalty-free, worldwide license, with the right to grant sublicenses, under the Assigned Patent Rights solely in order to research, develop, make, have made, use, market, offer to sell, distribute, sell and import Licensed Products in the Field.

13.1 Assignment. Neither this Agreement nor any of the rights or obligations hereunder may be assigned by either Party without the prior written consent of the other Party, except (a) each Party may assign this Agreement, in whole or in part, to an Affiliate of the assigning Party; provided, that the assigning Party guarantees the performance of such Affiliate of its obligations hereunder; (b) each Party may assign this Agreement, in whole, to a person who acquires all or substantially all of the business of the assigning Party by merger, sale of assets or otherwise (a “Sale Event”); and (c) each Party may exercise its rights or fulfill its obligations through its Affiliates, consultants, subcontractors and sublicensees; provided, that, such persons are bound by the corresponding obligations of such Party and such Party shall remain liable hereunder for the performance of its obligations hereunder. Any assignment not in accordance with the foregoing shall be void. Notwithstanding anything to the contrary herein, Calando shall not (i) assign this Agreement, in whole or in part, to any person unless Calando simultaneously assigns to such person all right, title and interest in, to and under the Licensed IP, the Caltech Agreement and the Caltech Side Letter, and (ii) assign any right, title or interest in or to the Licensed IP, except subject to the rights of Cerulean under this Agreement. This Agreement shall be binding upon, and shall inure to the benefit of, all permitted successors and assigns.

13.2 Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of Delaware, excluding its conflicts of laws provisions.

13.3 Dispute Resolution. Any dispute, controversy or claim arising out of or relating to this Agreement, or the breach, termination or invalidity thereof, shall be resolved as follows:

(a) The chief executive officers of the Parties shall attempt to resolve such dispute through good faith negotiation. Any such resolution of a referred dispute by the chief executive officers shall be final and binding on the Parties.

(b) If the Parties’ chief executive officers cannot resolve such dispute within thirty (30) days after either Party provides written notice of such dispute, then either Party may make a written demand for formal dispute resolution.

(c) Within thirty (30) days after such written demand, the Parties shall conduct a non-binding mediation administered by the American Arbitration Association in accordance with its commercial mediation rules. Unless otherwise mutually agreed upon by the Parties, the mediation proceedings shall be conducted at the location chosen by the Party not originally requesting the resolution of the dispute. The Parties shall share equally the cost of the mediation, including filing and hearing fees and the cost of the mediator(s). Each Party shall have the right, at its own expense, to be represented by counsel in such a proceeding.

(d) If such dispute is not resolved following mediation pursuant to Section 13.3(c), either Party may seek any remedy, at law or in equity, that may be available to it.

(e) Notwithstanding the foregoing provisions of this Section 13.3, each Party shall have the right at any time to institute judicial proceedings against the other Party or anyone acting by, through or under such other Party, in order to enforce the instituting Party’s rights hereunder through reformation of contract, specific performance, injunction or similar equitable relief.

13.5 Notices.

The effective date of the notice shall be the actual date of receipt by the receiving Party.

13.6 No Agency. Nothing herein shall be deemed to constitute either Party as the agent or representative of the other Party or both Parties as joint venturers or partners for any purpose. Neither Party shall be responsible for the acts or omissions of the other Party, and neither Party will have authority to speak for, represent or obligate the other Party in any way without prior written authority from the other Party. Except for the Calando Indemnitees and the Cerulean Indemnitees, no person shall be a third party beneficiary of this Agreement.

13.7 Entire Agreement. This Agreement contains the full understanding of the Parties with respect to the subject matter hereof and supersedes all prior understandings and writings relating thereto, including the Prior Confidentiality Agreement; provided, however, that the Parties agree and acknowledge that the Platform Agreement, the Escrow Agreement and the Caltech Side Letter are being entered into concurrently herewith or have been entered into prior to the Effective Date and shall remain in effect.

13.8 Force Majeure. Neither Party will be held liable or responsible to the other Party nor be deemed to have breached this Agreement for failure or delay in fulfilling or performing any provision of this Agreement when such failure or delay results from causes beyond the reasonable control of the affected Party, which may include embargoes, acts of war (whether declared or not), insurrections, riots, civil commotions, acts of terrorism, strikes, lockouts or other labor disturbances, or acts of God. The affected Party will notify the other Party of such force majeure circumstances as soon as reasonably practical and will make every reasonable effort to mitigate the effects of such force majeure circumstances.

13.9 Severabilitv. If any provision of this Agreement is held by a court of competent jurisdiction to be unenforceable because it is invalid or in conflict with any law of any relevant jurisdiction, the validity of the remaining provisions shall not be affected, and the rights and obligations of the Parties shall be construed and enforced as if the Agreement did not contain the particular provisions held to be unenforceable.

13.10 Export Compliance. The Parties acknowledge that the exportation from the United States of materials, products and related technical data (and the re-export from elsewhere of United States origin items) may be subject to compliance with United States export laws. Each Party shall comply with all applicable laws (whether U.S. or foreign) relating to the export, re-export, or release of any materials, products or their related technical data.
