On September 3, 2013, HedgePath Pharmaceuticals, Inc., a Delaware corporation (the “Company”), entered into an exclusive Supply and License Agreement (the “Supply and License Agreement”) with Mayne Pharma International Pty Ltd, a company incorporated in Australia (“Mayne Pharma”), pursuant to which Mayne Pharma has agreed to: (i) supply the Company with its patented formulation of the drug itraconazole, known as SUBA^TM-Itraconazole, in a particular dose formulation (the “Product”) for the treatment of human patients with cancer via oral administration (the “Field”) (with the initial areas of investigation being prostate, lung and skin cancer) in the United States (the “Territory”), (ii) provide the Company with an exclusive license to use and develop the intellectual property related to the Product in the Field and in the Territory and (iii) participate in a joint development committee with the Company (“JDC”) to clinically develop the Product in the Field and in the Territory. The Company will pursue the development of the Product for treatment of a variety of cancers with a focus on clinical development, seeking regulatory approvals and, if regulatory approval is obtained, marketing in the United States.

The Supply and License Agreement is attached to this Current Report as Exhibit 10.1. All descriptions of the Supply and License Agreement herein are qualified in their entirety to the text of Exhibit 10.1 hereto, which is incorporated herein by reference.

Pursuant to the Supply and License Agreement, the Company, with the assistance of Mayne Pharma through the JDC and subject to certain approval rights of Mayne Pharma, will develop and exploit the Product through a development plan which will be authorized by the JDC and updated as necessary. The license granted to the Company under the Supply and License Agreement may only be assigned or sub-licensed with the prior approval of Mayne Pharma. In addition, in support of the exclusive nature of the Supply and License Agreement, during the term, Mayne Pharma is prohibited from directly or indirectly importing, promoting, marketing, distributing or selling the Product in the Territory and in the Field. If any other form of the Product manufactured by Mayne Pharma is sold as a result of any off label use, the Company shall be entitled to a royalty on such off-label sales. Further, the Company may not develop products that are competitive with the Product, which period extends for a certain period following the end of the term.

Under the Supply and License Agreement, the Company is responsible for obtaining all of its requirements for the Product from Mayne Pharma, including for use in clinical trials, importation, promotion, marketing, sale and distribution in the Territory. The Company and Mayne Pharma have established certain minimum floor prices that the Company must pay per unit of the Product and minimum order quantities for the Product.

Any intellectual property created by the Company, either on its own or jointly with Mayne Pharma, relating to the Product in the Field will be owned by the Company, except that the Company has granted Mayne Pharma an exclusive, perpetual, irrevocable, royalty free licence to copy and exploit such developed intellectual property outside of the United States.

Although the Supply and License Agreement is effectively immediately, it remains subject to early termination by Mayne Pharma if certain conditions (the “Conditions”) are not met by December 16, 2013. Such Conditions include: (i) the Company shall have raised $5 million in an equity financing (or such lesser amount as may be agreed to by Mayne Pharma) (the “Equity Financing”); (ii) a representative of Mayne Pharma shall have been appointed to the Company’s board of directors, and Mayne Pharma and the Company shall have entered into an agreement granting Mayne Pharma certain board appointment rights; (iii) Mayne Pharma shall, pursuant to customary definitive documentation to be negotiated by the parties, acquire from the Company, as part of the consideration under the Supply and License Agreement,

170,000.74 shares of the Company’s Series A Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”), representing, on an as fully converted, fully diluted basis, 45% of the issued and outstanding shares of capital stock of the Company (prior to the Equity Financing and the anticipated adoption by the Company of an equity incentive plan); (iv) Hedgepath, LLC (an affiliate of the Company who currently has the right to receive shares of Series A Preferred Stock) (“Hedgepath”)), Nicholas J. Virca (the Company’s President and Chief Executive Officer) (“Virca”) and Mayne Pharma shall have entered into an agreement providing for certain restrictions on transfers and ownership of Company equity; (v) the Company and Mayne Pharma shall have entered into an agreement granting Mayne Pharma and accredited investors introduced to the Company by Mayne Pharma certain participation rights in future Company equity financings; (vi) the Company shall have (a) received a written estimate from a credible contract research organization reasonably acceptable to Mayne Pharma relating to the Company’s proposed clinical trials and (b) provided reasonable assurances to Mayne Pharma that the Product will be available for commercial launch by a specified date; and (vii) Virca and Frank E. O’Donnell, Jr., the Company’s Executive Chairman, shall have entered into customary agreements regarding their positions with the Company.

Subject to earlier termination if the Conditions are not met as described above, the term of the Supply and License Agreement shall last until the later of: (i) 10 years from the date of the first commercial sale of the Product for the treatment of human patients with cancer via oral administration or (ii) the date on which all issued patents of Mayne Pharma or any of its affiliates referred to in the Supply and License Agreement have lapsed or expired.

The Supply and License Agreement is further subject to termination in certain circumstances, including: (i) by either party in the event of (a) a material default that is not cured within a specified number of days after notice is received or is not capable of remedy, (b) if marketing authorizations for the Product are not obtained prior to the agreed upon target launch date for the Product or (c) a force majure event precluding performance by the other party for a specified period of time, (ii) the voluntary or involuntary bankruptcy of either party, (iii) by Mayne Pharma if either Hedgepath or Virca breach their respective agreements with Mayne Pharma to restrict the sale and or transfer of their shares of Company equity and such breach is not cured within a specified number of days after notice is received or such breach is not capable of remedy, (iv) by Mayne Pharma if the Company breaches certain of its obligations relating to the Conditions (once they are satisfied) and such breach is not cured within a specified number of days after notice is received or such breach is not capable of remedy, (v) by Mayne Pharma if, under certain circumstances, the Company fails to purchase the minimum agreed upon amounts of Product in any given year or (vi) by Mayne Pharma, under certain circumstances, upon a change of control of the Company.
