11.2 Indemnification by Licensee.

11.3 Procedures. The Party seeking indemnification under this Section 11 (the “Indemnified Party”) shall give prompt notice to the Party against whom indemnity is sought (the “Indemnifying Party”) of the assertion or commencement of any claim for indemnification pursuant to this Section 11, and shall provide the Indemnifying Party such information with respect thereto that the Indemnifying Party may reasonably request. The failure to give such notice will relieve the Indemnifying Party of its indemnification obligations hereunder only to the extent that the Indemnifying Party has suffered actual prejudice thereby. The Indemnifying Party shall assume and control the defense and settlement of any such action, suit or proceeding at its own expense. The Indemnified Party shall, if requested by the Indemnifying Party, cooperate in all reasonable respects in such defense, at the Indemnifying Party’s expense, subject to the following. The Indemnified Party will be entitled at its own expense to participate in such defense and to employ separate counsel for such purpose. For so long as the Indemnifying Party is diligently defending any action, suit or proceeding pursuant to this Section 11, the Indemnifying Party will not be liable under this Section 11 for any settlement effected without its consent. No Party shall enter into any compromise or settlement which commits the other Party to take, or to forbear to take, any action without the other Party’s prior written consent.

11.4 Consequential Damages. NEITHER PARTY SHALL BE LIABLE TO OR OTHERWISE RESPONSIBLE TO THE OTHER PARTY HERETO FOR ANY LOSS OF PROFITS, DIMINUTION IN VALUE, OR INCIDENTAL, INDIRECT, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR PUNITIVE DAMAGES THAT ARISE OUT OF OR RELATE TO THIS AGREEMENT OR THE PERFORMANCE OR BREACH HEREOF OR OTHERWISE AND WHETHER IN CONTRACT, TORT, STRICT LIABILITY OR OTHERWISE; PROVIDED, THAT, THE FOREGOING LIMITATION SHALL NOT APPLY: (I) TO A PARTY’S INDEMNIFICATION OBLIGATIONS PURSUANT TO SECTIONS 11.1 AND 11.2 ABOVE; (II) TO ANY GROSSLY NEGLIGENT ACT OR WILLFUL MISCONDUCT OF A PARTY; OR (III) TO A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS PURSUANT TO SECTION 9 HEREOF.

11.5 Insurance.

(a) General Liability. Each Party shall maintain as and when available comprehensive general liability insurance, including blanket contractual liability insurance through the Term and for five (5) years thereafter, which insurance shall afford limits of not less than US$3,000,000 for each occurrence for bodily injury liability, personal injury liability, products liability, property damage liability, contractual liability and completed operations liability. Each Party shall ensure that such insurance will include coverage for defense costs.

(b) Product Liability. Each Party shall maintain as and when available and thereafter throughout the Term product liability insurance on commercially standard terms for the pharmaceutical manufacturing industry, with a reputable insurer, in an amount not less than US$5,000,000 per occurrence and US$5,000,000 in the annual aggregate.

(c) Certificate of Insurance. Each Party will provide, upon request and as and when available, the other with certificate(s) of insurance evidencing the above and showing the name of the issuing company, the policy number, the effective date, the expiration date and the limits of liability. Each Party shall cause its insurance policy to name the other Party hereto as an additional insured. Each Party’s general liability insurance policy shall contain a waiver of subrogation rights which that Party’s insurer(s) may have against the other Party.

12.1 After the completion of equity investment as provided in Section 6.2, Licensee may examine, upon reasonable prior written request having been made to Licensor, but not more than twice per year, the books, records and accounts of Licensor. Licensee shall be entitled to receive reasonable information, including management accounts and operating statistics and other business and financial information, which exist at the time of request, to keep it properly informed about the business and affairs of Licensor and relevant to its interest as a shareholder.

12.2 Licensor shall provide reasonable access to Licensee’s personnel, upon reasonable notice and during normal business hours, but not more than twice per year, to access such books, records, accounts and other information relating to Licensor, which exist at the time of request, as may be necessary for them to review the information provided to Licensee pursuant to Sections 12.1.

12.3 Any information or documents provided to or made available for review by Licensee shall constitute Confidential Information and shall be protected accordingly as provided under Section 9 above.

Section 13. Term and Termination

13.1 Term and Rules Post Expiration: This Agreement shall enter into full force and effect at the Effective Date and as provided under this Section 13, the term of this Agreement (the “Term”) shall be on a Licensed Product by Licensed Product basis and on a country-by-country basis and shall continue until the expiration of the last-to-expire valid and applicable patent within the patent rights in the given country of the Territory, or following fifteen (15) years from the first commercial sale of each Licensed Product in such country, whichever is later.

13.2 Term and Rules Post Termination:

(a) In the event either Party is in breach of any material obligation hereunder or under the RGN-137 License Agreement (the “Breaching Party”), the non-breaching Party may give written notice to the Breaching Party specifying the claimed particulars of such breach, and in the event such material breach is not cured, within sixty (60) days following the date of such written notification, without prejudice to any other rights and remedies available at any time to the non-breaching Party, the non-breaching Party shall have the right thereafter to terminate this Agreement by giving thirty (30) days prior written notice to the Breaching Party to such effect.

(b) Termination for Governmental Action. Either Party may terminate this Agreement upon ten (10) days’ prior written notice in the event that any Governmental Authority takes any action or raises any objection (“Governmental Action”) that prevents Licensee, for a period of not less than one hundred eighty (180) days, from importing, exporting, purchasing or selling the Licensed Product in the Territory, or that has the effect of making Licensor’s manufacture of the Licensed Product unlawful.

(c) Termination by Licensor for Patent Challenge. Licensor may terminate this Agreement in its entirety immediately upon written notice to Licensee if Licensee or its Affiliates, Sublicensees or Distributors (directly or indirectly, individually or in association with any person or entity) challenges the validity, enforceability or scope of any Licensed Patents anywhere in the world.

(d) Termination or Conversion Pursuant to the PHS License. In the event that PHS terminates the PHS License under Article 13 therein or rescinds a Licensed Field of Use (as that term is defined in the PHS License) that includes any portion of the Field in which Licensee is licensed hereunder, Licensee may, at its option:

25 | Page*** Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

(i) terminate this Agreement; or

(ii) convert this Agreement to a license between Licensee, on the one hand, and Licensor and PHS, on the other hand, with such conversion subject to the approval of PHS, which shall not be unreasonably withheld, and contingent upon Licensee’s acceptance of all of the provisions of the PHS License.

(e) Termination for Bankruptcy. To the extent permitted under applicable Law, if at any time during the Term, 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 sixty (60) days 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, the Bankrupt Party shall not have the right to terminate any license granted herein. The term “Event of Bankruptcy” means: (i) filing in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Bankrupt Party or of its assets; (ii) proposing a written agreement of composition or extension of a Bankrupt Party’s debts; (iii) being served with an involuntary petition against the Bankrupt Party, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof; (iv) proposing or being a party to any dissolution or liquidation when insolvent; or (v) 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 U.S.C. § 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 U.S.C. § 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 U.S.C. § 365(n) of the Bankruptcy Code, and any other relevant laws.

(iv) Licensee shall assign (or cause its Affiliates to assign) to Licensor all agreements with any Third Party with respect to the conduct of clinical trials for the Licensed Product, including agreements with contract research organizations, clinical sites and investigators, unless expressly prohibited by any such agreement or unless such agreement covers clinical trials for products in addition to the Licensed Products (in which case Licensee shall cooperate with Licensor in all reasonable respects to secure the consent of such Third Party to such assignment or to the conclusion of a new agreement between the Licensor and the Third Party on terms substantially similar to the agreement between Licensee and the Third Party), and Licensor shall assume all obligations under all such agreements.

Section 14. Miscellaneous

14.1 Waiver. The waiver by any Party of a breach of any provision of this Agreement shall not operate, or be construed, as a waiver of any subsequent breach.

14.3 Entire Agreement. This Agreement (including all exhibits and attachments hereto, all of which are incorporated herein by reference) constitutes the entire agreement between the Parties (and their Affiliates) with respect to the subject matter hereof and thereof, and supersedes all prior agreements and understandings, whether oral or written, between the Parties, except for the Confidential Disclosure Agreement described in Section 9.7.

If Licensor is involved in a Change of Control, the Intellectual Property of the Third Party that has become an Affiliate of Licensor through the transaction that constituted such Change of Control and the Intellectual Property of such Third Party’s Affiliates existing as of the closing of such Change of Control or developed outside of any activities under this Agreement, shall be automatically excluded from the definitions of Licensed Patents and Licensed Know-How licensed to Licensee under this Agreement.

14.6 Independent Contractor. This Agreement shall not be construed as constituting a partnership, joint venture or any other form of legal association that would impose liability upon one Party for the act or failure to act of the other Party, or as providing either Party with the right, power or authority (express or implied) to create any duty or obligation of the other Party.

14.7 Third Party Beneficiaries.

(c) Arbitration. If all good faith attempts to resolve a dispute through negotiations and mediation pursuant to Sections 14.814.8(a) and (b) have failed after sixty (60) days from notice provided pursuant to Section 14.8(a), then upon the request of either Party, the dispute shall be finally resolved by binding arbitration administered by I.C.C.

Each Party hereby waives any defenses it may have to the personal jurisdiction and venue of such courts to resolve such disputes, including without limitation the defense of forum non conveniens, and each Party agrees not to file any motion to seek any relief under any forum non conveniens defense.
