Except as set forth in this Sublicense Agreement or as required by Law, neither Party shall make any press release or other public announcement or other public disclosure to a Third Party concerning the existence of or terms of this Sublicense Agreement, without the prior written consent of the other Party, which consent shall include agreement upon the nature and text of such release, announcement or other disclosure and shall not be unreasonably withheld or delayed; provided, however, that the foregoing will not restrict disclosures made in connection with any filing of information or materials with a stock exchange or the SEC or any stockholders’ letter to private investors on the condition that if the information is for investors, such investors agree to be bound by confidentiality obligations consistent with this Sublicense Agreement. Each Party agrees to provide to the other Party a copy of any such press release as soon as reasonably practicable under the circumstances prior to its scheduled release, and consider comments from such Party in good faith. Each Party shall have the right to review and recommend changes to any press release; provided, however, that such right of review and recommendation shall only apply for the first time that specific information is to be disclosed, and shall not apply to the subsequent disclosure of substantially similar information that has previously been disclosed unless there have been material developments relating to the Compound or the Licensed Product since the date of the previous disclosure; provided, further, that each Party shall provide to the other Party reasonable advance notice of any such subsequent disclosure. Without limiting the generality of any of the foregoing, it is understood that the Parties or their Affiliates may make disclosure of this Sublicense Agreement and the terms hereof in accordance with the rules and regulations of the SEC, other governmental authority, or securities exchange, may file this Sublicense Agreement as an exhibit to any filing with the SEC, other governmental authority, or securities exchange, and may distribute any such disclosure or filing in the ordinary course of its business.

(e)    Either Party may, without prejudice to any other remedies available to it under this Agreement or at law or in equity, terminate this Sublicense Agreement prior to the expiration of the Term in the event that the other Party materially breaches or defaults in the performance of any of its obligations hereunder, and fails to cure such breach within (i) thirty (30) days after notice is provided to the breaching Party, in the event the breach is a non-payment of any amount due hereunder that is not being disputed in good faith or (ii) sixty (60) days after notice of such breach is provided to the breaching Party for other causes of breach; provided that the Parties agree to negotiate in good faith prior to such termination. Termination will become effective at the end of the 30- or 60-day cure period unless the breaching Party cures such breach during such 30- or 60-day period, or if such breach is not susceptible to cure within such 30- or 60-day period, the breaching Party has commenced and is diligently pursuing a cure. The right of either Sublicensor or Sublicensee to terminate this Sublicense Agreement as provided in this SECTION 8.1 will not be affected in any way by such Party’s waiver or failure to take action with respect to any previous breach or default.

SECTION 8.2. Effect of Expiration or Termination; Survival.

(a)    Expiration or termination of this Sublicense Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination, including all accrued payment obligations arising under Section 4.3.

(c)    Sublicensee and its Affiliates shall have the right to sell or otherwise dispose of the stock of any Licensed Products subject to this Sublicense Agreement on hand as of the termination of this Sublicense Agreement. Within thirty (30) days after the effective date of termination of this Sublicense Agreement, Sublicensee shall notify Sublicensor of the amount of Licensed Products that Sublicensee and its Affiliates then have on hand. Sublicensee shall have the right to sell in the Territory (subject to Regulatory Approvals), such remaining stock of Licensed Products for a period ending upon the earlier of: (i) Sublicensee’s and its Affiliates’ sale of all such remaining Licensed Products, or (ii) 6 months after such termination, and terms and conditions of this Sublicense Agreement shall apply to such Licensed Products so sold. Sublicensor hereby grants Sublicensee, effective upon termination of this Sublicense Agreement, a non-exclusive license to sell such Licensed Products in the Field in the Territory, subject to payment of all related amounts due under this Sublicense Agreement. Any remaining quantities of Licensed Products not sold during this period shall, at Sublicensor’s election, either be destroyed by Sublicensee at Sublicensee’s cost or sold to Sublicensor at Sublicensee’s procurement cost for such Licensed Products. In the event that Sublicensee does not elect to exercise its right, pursuant to this Section 8.2(c), to sell or otherwise dispose of the remaining stock of any Licensed Products, such remaining stock shall be transferred to Sublicensor at no cost to Sublicensor.

SECTION 9.1. Indemnity. For purposes of this SECTION 9.1, “Sublicensor Indemnified Parties” refers to Sublicensor, its Affiliates and the officers, directors, employees, shareholders, agents and successors and assigns of Sublicensor and its Affiliates, and “Sublicensee Indemnified Parties” refers to Sublicensee, its Affiliates and officers, directors, employees, shareholders, agents and successors and assigns of Sublicensee and its Affiliates.

SECTION 9.2. Licensee Indemnification. Sublicensee shall defend the Sublicensor Indemnified Parties from and against Claims that are brought by a Third Party, and shall indemnify and hold harmless to the fullest extent permitted by law the Sublicensor Indemnified Parties from and against any and all Losses, that arise out of or are attributable to (i) Sublicensee’s gross negligence or willful misconduct in exercising or performing any of its rights or obligations under this Sublicense Agreement; or (ii) a material breach by Sublicensee of any of its obligations, representations, warranties or covenants under this Sublicense Agreement; provided, however, that Sublicensee shall not be obligated to indemnify Sublicensor under this SECTION 9.2, to the extent such Claim arose out of the gross negligence or willful misconduct of Sublicensor or to the extent such Claim is covered by Sublicensor’s indemnity below.

SECTION 9.3. Licensor Indemnification. Sublicensor shall defend the Sublicensee Indemnified Parties from and against all Claims, in each case that are brought by a Third Party, and shall indemnify and hold harmless to the fullest extent permitted by law the Sublicensee Indemnified Parties from and against any and all Losses that arise out of such Claims that are attributable to (i) the use of the Intellectual Property in the Compound or Licensed Products as authorized by this Sublicense Agreement infringing, misappropriating or violating the Intellectual Property of such Third Party, (ii) Sublicensor’s gross negligence or willful misconduct in exercising or performing any of its rights or obligations under this Sublicense Agreement; or (iii) a material breach by Sublicensor of any of its obligations, representations, warranties or covenants under this Sublicense Agreement; provided, however, that Sublicensor shall not be obligated to indemnify Sublicensee under this SECTION 9.3, to the extent such Claim arose out of the gross negligence or willful misconduct of Sublicensee.

Concurrent with the provision of notice pursuant to this SECTION 9.4(a), the indemnified Party shall provide to the other Party copies of any complaint, summons, subpoena or other court filings or correspondence related to such Claim and will give such other information with respect thereto as the other Party shall reasonably request. The indemnifying Party and indemnified Party shall meet to discuss how to respond to such Claim. Failure to provide prompt notice shall not relieve any Party of the duty to defend or indemnify unless such failure materially prejudices the defense of any matter. Each Party agrees that it will take reasonable steps to minimize the burdens of the litigation on witnesses and on the ongoing business of the indemnified Parties including by making reasonable accommodations to witnesses’ schedules when possible and seeking appropriate protective orders limiting the duration and/or location of depositions.
