8.	License obligations:

Arcion license agreement

On March 26, 2013, the Company entered into a license agreement with Arcion Therapeutics, Inc. (the “Arcion Agreement”) pursuant to which Arcion granted to the Company an exclusive commercial world-wide license, with rights of sublicense, under certain patent and other intellectual property rights related to in-process research and development to develop, manufacture, market, and sell gel products containing clonidine (or a derivative thereof) for the treatment of painful diabetic neuropathy (“PDN”) and other indications (the “Arcion Products”).

On December 13, 2016, the Company announced that its Phase 2b clinical study assessing the efficacy and safety of Clonidine Topical Gel failed to show a statistically significant difference in pain relief between Clonidine Topical Gel and placebo. As a result, the Company has discontinued further development of the product as of December 31, 2016.

Evonik definitive development and exclusive license option agreement:

On October 27, 2014, the Company entered into a definitive Development and Exclusive License Option Agreement (the “Development Agreement”) with Evonik Corporation, (“Evonik”) to develop and commercialize an injectable, extended release, microparticle formulation of buprenorphine for the treatment of opioid dependence (the “Evonik Product”). Under the Development Agreement, the Company also has the right to pursue development of the Evonik Product for pain management.

Under the Development Agreement, Evonik has also granted to the Company two exclusive options to acquire exclusive worldwide licenses, with rights of sublicense, to certain patents and other intellectual property rights of Evonik to develop and commercialize certain products containing buprenorphine. If these options are exercised, such licenses would be memorialized in the Evonik License Agreement (as defined below).

Pursuant to the Development Agreement, Evonik is responsible for using commercially reasonable efforts to develop a formulation for the Evonik Product in accordance with a work plan mutually agreed upon by the parties (the “Evonik Project”). Should the Evonik Project proceed past the formulation stage, Evonik also has the right to manufacture clinical and commercial supplies of Evonik Product, such manufacturing arrangement to be negotiated by the parties in good faith in a formal License and Supply Agreement(s) (the “Evonik License Agreement”), with such Evonik License Agreement covering Evonik’s intellectual property rights to be entered into between the parties if certain conditions are met and terms are mutually agreed upon.

Should Evonik and the Company enter into the License Agreement following the attainment of a Phase 1 ready formulation of the Evonik Product for one or both of the opioid dependence or pain management indications, the Company would pay Evonik a non-refundable, non-creditable one-time payment in conjunction with certain future regulatory filings and approvals and royalties on net sales of the Evonik Product.

The Development Agreement contains customary termination provisions, and the Company may additionally terminate the Development Agreement at any time after the completion of certain enumerated tasks as provided in the Development Agreement, for any reason or no reason, by providing written notice of termination to Evonik. Upon termination of the Development Agreement, Evonik will be paid any amounts owed to Evonik in accordance with the estimated budget for work performed under the Development Agreement through the effective date of termination, including any reasonable, documented, non-cancelable third-party costs and any reasonable, documented wind-down costs reasonably incurred by Evonik in connection with the Evonik Project. Should the Company terminate for reasons other than for a material, uncured breach by Evonik or Evonik’s bankruptcy, Evonik shall have the right to use any and all data and intellectual property generated under the Evonik Project for any purpose.

This product candidate is currently in the pre-clinical stage of development. An Investigational New Drug Application (“IND”) for opioid dependence was filed in the fourth quarter 2016.
