INDEMNIFICATION

10.1Indemnification by Catalyst. Catalyst shall indemnify and hold harmless ISU, and its directors, officers, employees, agents, Affiliates and contractors (collectively, the “ISU Indemnitees”), from and against all losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs (collectively, “Liabilities”), resulting from any claims, demands, actions or other proceedings by any Third Party (“Claims”) to the extent resulting from (a) the breach of any representation, warranty or covenant by Catalyst under this Agreement or (b) the negligence or willful misconduct of Catalyst or its agents, Affiliates and contractors. The foregoing indemnity obligation shall not apply to the extent that (i) the ISU Indemnitees fail to comply with the indemnification procedures set forth in Section 10.3 and Catalyst’s defense of the relevant Claims is prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any activity set forth in Section 10.2(a), or 10.2(b) for which ISU is obligated to indemnify the Catalyst Indemnitees under Section 10.2.

10.2Indemnification by ISU. ISU shall indemnify and hold harmless Catalyst, and its directors, officers, employees, agents, Affiliates and contractors (collectively, the “Catalyst Indemnitees”), from and against all Liabilities resulting from any Claims to the extent resulting from (a) the breach of any representation, warranty or covenant by ISU under this Agreement, or (b) the negligence or willful misconduct of ISU or its agents, Affiliates and contractors. The foregoing indemnity obligation shall not apply to the extent that (i) the Catalyst Indemnitees fail to comply with the indemnification procedures set forth in Section 10.3 and ISU’s defense of the relevant Claims is prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any activity set forth in Section 10.1(a) or 10.1(b) for which Catalyst is obligated to indemnify the ISU Indemnitees under Section 10.1.

10.3Indemnification Procedures. The Party claiming indemnity under this Article 10 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of such Claim. The Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice, and the Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense. The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. Each Party shall not settle or compromise any Claim without the prior written consent of the other Party, which consent shall not be unreasonably withheld, delayed or conditioned. If the Parties cannot agree as to the application of the foregoing Sections 10.1 and 10.2, each may conduct separate defenses of the Claim, and each Party reserves the right to claim indemnity from the other in accordance with this Article 10 upon the resolution of the underlying Claim.

10.4Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

Each Party shall deliver certificates of insurance evidencing coverage to the other Party promptly after the execution of this Agreement and annually thereafter. All policies provided for herein shall expressly provide that such policies shall not be cancelled, terminated or altered without at least [* * *] prior written notice to the insured Party, and each insuring Party shall immediately notify the insured party in the event that a policy provided for herein is cancelled, terminated or altered.

Article 11
CONFIDENTIALITY

11.1Confidentiality. During the Term and for a period of [* * *] thereafter, each Party shall maintain all Confidential Information of the other Party in trust and confidence and shall not, without the written consent of the other Party, disclose any Confidential Information of the other Party to any Third Party or use any Confidential Information of the other Party for any purpose other than as provided in this Agreement. The confidentiality obligations of this Section 11.1 shall not apply to Confidential Information to the extent that the receiving Party can establish by competent evidence that such Confidential Information: (a) is publicly known prior or subsequent to disclosure without breach of confidentiality obligations by such Party or its employees, consultants or agents; (b) was in such Party’s possession at the time of disclosure without any restrictions on further disclosure; (c) is received by such receiving Party, without any restrictions on further disclosure, from a Third Party who has the lawful right to disclose it, or (d)

is independently developed by employees or agents of the receiving Party who had no access to the disclosing Party’s Confidential Information. Notwithstanding the foregoing, the Parties agree that all pre-clinical and clinical data regarding DalcA, all correspondence with Regulatory Authorities anywhere in the world regarding DalcA, and all information related to the manufacturing and testing of DalcA shall be Confidential Information of Catalyst and the terms and conditions of this Agreement shall be Confidential Information of both Parties.

11.2Authorized Disclosure. Nothing herein shall preclude a Party from disclosing the Confidential Information of the other Party to the extent:

(a)such disclosure is reasonably necessary (i) for the filing or prosecuting of Patents as contemplated by this Agreement; (ii) to comply with the requirement of Regulatory Authorities with respect to obtaining and maintaining Regulatory Approval (or any pricing and reimbursement approvals) of a Product; or (iii) for prosecuting or defending litigations as contemplated by this Agreement;

(b)such disclosure is reasonably necessary to its employees, agents, consultants, contractors, licensees or sublicensees on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement; provided that in each case, the disclosees are bound by written obligations of confidentiality and non-use consistent with those contained in this Agreement;

(c)such disclosure is reasonably necessary to any bona fide potential or actual investor, acquiror, merger partner, sublicensee or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition, sublicense or other business relationship; provided that in connection with such disclosure, such Party shall use all reasonable efforts to inform each disclosee of the confidential nature of such Confidential Information and cause each disclosee to treat such Confidential Information as confidential;

(d)such disclosure is reasonably necessary to comply with applicable Laws, including regulations promulgated by applicable security exchanges, a valid order of a court of competent jurisdiction, administrative subpoena or order.

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 11.2(a) or 11.2(d), such Party shall promptly notify the other Party of such required disclosure and shall use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure.

11.3Return of Confidential Information. Promptly after the termination or expiration of this Agreement for any reason, each Party shall return to the other Party all tangible manifestations including, but not limited to, all written materials of such other Party’s Confidential Information at that time in the possession of the receiving Party.

11.4Publicity.

(a)[* * *]. If ISU desires to make any other public announcement concerning the material terms or other matters related to this Agreement, ISU shall give [* * *] advance notice of the proposed text of such announcement to Catalyst for its prior review and approval (except as

otherwise provided herein), such approval not to be unreasonably withheld. If Catalyst desires to make a public announcement concerning the material terms or other matters related to this Agreement, Catalyst shall give at least [* * *] prior written notice of the proposed text of such announcement to ISU for its prior review (except as otherwise provided herein). Notwithstanding the foregoing, ISU shall not be required to seek the permission of Catalyst to repeat any information regarding the terms of this Agreement or DalcA that has already been publicly disclosed, provided such information remains accurate as of such time.

(b)In addition, the Parties acknowledge that either or both Parties may be obligated to disclose the material terms of this Agreement and to file under applicable law and regulation a copy of this Agreement with the United States Securities and Exchange Commission or similar stock exchange authorities or other governmental authorities. Each Party shall be entitled to make such disclosure and required filing; provided, however, that it requests confidential treatment of the commercial terms and sensitive technical terms hereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party shall provide the other Party with a copy of this Agreement marked to show provisions for which such Party intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s comments thereon, if timely provided, to the extent consistent with the legal requirements, with respect to the filing Party, governing disclosure of material agreements and material information that must be publicly filed.

11.5Technical Publication. ISU may not publish peer reviewed manuscripts or give other forms of public disclosure, such as abstracts and media presentations of results of studies carried out under this Agreement, without Catalyst’s prior written consent.

11.6Equitable Relief. Each Party acknowledges that its breach of Article 11 of this Agreement may cause irreparable injury to the other Party for which monetary damages may not be an adequate remedy. Therefore, each Party shall be entitled to seek injunctive and other appropriate equitable relief to prevent or curtail any actual or threatened breach of the obligations relating to Confidential Information set forth in this Article 11 by the other Party. The rights and remedies provided to each Party in this Article 11 are cumulative and in addition to any other rights and remedies available to such Party at law or in equity.

Article 12
TERM AND TERMINATION

12.1Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 12, shall remain in effect on a Product-by-Product and country-by-country basis until the expiration of the Royalty Term of such Product in such country (the “Term”). On expiration in the particular country and for the particular Product, the licenses granted in Sections 2.1 and 2.2 for the Product shall automatically convert to be perpetual, irrevocable and non-exclusive in such country.

12.2Termination for Breach.

(a)Each Party shall have the right to terminate this Agreement in its entirety immediately upon written notice to the other Party if the other Party materially breaches its obligations under this Agreement and, after receiving written notice identifying such material breach in reasonable detail, fails to cure such material breach within [* * *] from the date of such notice (or [* * *] from the date of such notice in the event such material breach is solely based on the breaching Party’s failure to pay any amounts due hereunder).

(b)If the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in a notice provided by the other Party in accordance with Section 12.2(a), and such alleged breaching Party provides the other Party notice of such dispute within the applicable cure period, then the non-breaching Party shall not have the right to terminate this Agreement under Section 12.2(a) unless and until an arbitrator, in accordance with Article 13, has determined that the alleged breaching Party has materially breached the Agreement and such breaching Party fails to cure such breach within the applicable cure period (measured as commencing after the arbitrator’s decision). It is understood and agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder.

12.3Termination for Bankruptcy. To the extent permitted under applicable Laws, if at any time during the Term of this Agreement, an Event of Bankruptcy (as defined below) relating to either Party (the “Bankrupt Party”) occurs, the other Party (the “Other Party”) shall have, in addition to all other legal and equitable rights and remedies available hereunder, the option to terminate this Agreement upon [* * *] written notice to the Bankrupt Party. It is agreed and understood that if the Other Party does not elect to terminate this Agreement upon the occurrence of an Event of Bankruptcy, except as may otherwise be agreed with the trustee or receiver appointed to manage the affairs of the Bankrupt Party, the Other Party shall continue to make all payments required of it under this Agreement as if the Event of Bankruptcy had not occurred, and the Bankrupt Party shall not have the right to terminate any license granted herein. The term “Event of Bankruptcy” means: (a) filing, in any court or agency pursuant to any statute or regulation of any state or country, (i) a petition in bankruptcy or insolvency, (ii) for reorganization or (iii) for the appointment of (or for an arrangement for the appointment of) a receiver or trustee of the Bankrupt Party or of its assets; (b) with respect to the Bankrupt Party, being served with an involuntary petition filed in any insolvency proceeding, which such petition is not dismissed within [* * *] after the filing thereof; (c) proposing or being a Party to any dissolution or liquidation when insolvent; or (d) making an assignment for the benefit of creditors. Without limitation, the Bankrupt Party’s rights under this Agreement shall include those rights afforded by 11 USAC. § 365(n) of the United States Bankruptcy Code (the “Bankruptcy Code”) and any successor thereto. If the bankruptcy trustee of a Bankrupt Party as a debtor or debtor-in-possession rejects this Agreement under 11 USAC. § 365(o) of the Bankruptcy Code, the Other Party may elect to retain its rights licensed from the Bankrupt Party hereunder (and any other supplementary agreements hereto) for the duration of this Agreement and avail itself of all rights and remedies to the full extent contemplated by this Agreement and 11 USAC. § 365(n) of the Bankruptcy Code, and any other relevant Laws.

12.4Termination by Mutual Consent. The Parties may terminate this Agreement upon the mutual agreement of both Parties.

12.5Effect of Termination.

12.7Survival.

Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement: Sections 5.2, 5.3, and 5.4 and Articles 7 (but with respect to 7.1, 7.2 and 7.3, only with respect to events that occur prior to termination), 8, 10, 11, 12, 13, and 14.

12.8Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by ISU are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code.

13.3Arbitration. If the Executive Officers of the Parties are not able to resolve such dispute referred to them under Section 13.2 within such [* * *] period, then subject to Section 13.4, such dispute shall be settled by binding arbitration in accordance with the then current rules of commercial arbitration of the American Arbitration Association (“AAA”).

Article 14
MISCELLANEOUS

14.1Entire Agreement; Termination of Prior Agreement; Amendment. This Agreement, together with the exhibits attached hereto and which are hereby incorporated herein, represents the entire agreement and understanding between the Parties with respect to its subject matter and supersedes and terminates any prior and/or contemporaneous discussions, representations or agreements, whether written or oral, of the Parties regarding the subject matter hereto, and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof (including the Prior Agreement). There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth in this Agreement. For the avoidance of doubt, the Parties agree that neither has any obligations under the Prior Agreement, which is hereby terminated in its entirety and superseded by the terms and conditions hereof. After the Effective Date, neither Party shall make any claim or demand whatsoever against the other Party or any of its officers, directors, shareholders, agents, employees, subsidiaries and Affiliates (each a “Released Party” and together the “Released Parties”) with

respect to the Prior Agreement, and each Party hereby irrevocably and forever releases all such Released Parties from any and all liabilities, demands, claims (including third Party claims), costs, losses, damages and expenses (including, without limitation, interest, penalties and attorney fees), known or unknown, contingent or otherwise, which such releasing Party may otherwise have against or recover from such Released Parties under the Prior Agreement, except as resulted from fraud, gross negligence or intentional misconduct by a Released Party. Amendments or changes to this Agreement shall be valid and binding only if in writing and signed by duly authorized representatives of the Parties.

14.2Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including an act of God, war, civil commotion, terrorist act, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such failure could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a skilled and experienced person engaged in the same type of undertaking under the same or similar circumstances). Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party. If a force majeure persists for more than [* * *], then the Parties shall discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such force majeure.

14.3Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in accordance with this Section 15.3, and shall be deemed to have been given for all purposes (a) when received, if hand-delivered or sent by confirmed facsimile or a reputable courier service, or (b) [* * *] after mailing, if mailed by first class certified or registered airmail, postage prepaid, return receipt requested.
