Item 1.01. Entry into a Material Definitive Agreement.

On March 5, 2014, HedgePath Pharmaceuticals, Inc., a Delaware corporation (the “Company”), entered into an Amendment No. 2 (the “Second Amendment”) to that certain Supply and License Agreement, dated September 3, 2014 (as amended, the “Agreement”), with Mayne Pharma International Pty Ltd, a company incorporated in Australia (“Mayne Pharma”). Pursuant to the Agreement, 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 to clinically develop the Product in the Field and in the Territory.

The Second Amendment amends the Agreement as follows:

(i) the date by which the Conditions (as defined below) must be met was extended from February 28, 2014 to March 31, 2014;

(ii) the Company has agreed to use reasonable efforts to progress the conduct of the activities set out in, and in accordance with, the development plan as set forth in the Agreement (the “Development Plan”), and to seek reimbursement of relevant amounts in accordance with the Agreement;

(iii) the Company and Mayne Pharma acknowledged and agreed that warrants may be issued in connection with an Equity Financing (as defined below) and further agreed that in the event that warrants are issued in connection with an Equity Financing, Mayne Pharma will receive a warrant on the same terms as the warrants issued in the Equity Financing for such a number of shares that will ensure that Mayne Pharma will hold at least 30% of the issued and outstanding shares of capital stock of the Company on a fully diluted, fully converted basis following the Equity Financing;

(iv) if the Company does not (i) submit a complete Investigational New Drug (“IND”) application to the United States Food and Drug Administration (the “FDA”) for the Product for at least one indication in the Field and commence dosing patients in at least two phase II or phase II/III clinical trials across at least two indications in the Field by March 31, 2015 or (ii) submit an application for a new drug application to the FDA for at least one indication by March 31, 2016, then Mayne Pharma may, by notice to Frank E. O’Donnell, Jr. M.D., the Company’s Executive Chairman, and Nicholas J. Virca, the Company’s President and Chief Executive Officer, require each of them to resign from the Company, in which case each of Hedgepath LLC, Mr. Virca and Dr. O’Donnell will forfeit all of their respective unvested Company options, and Mayne Pharma will have the right to purchase all issued and outstanding shares of the Company’s capital stock held by Mr. Virca and Dr. O’Donnell at market price, and neither Mr. Virca nor Dr. O’Donnell will be entitled to receive any severance or similar payments from the Company;

(v) in the event that Dr. O’Donnell or Mr. Virca are removed or resign from the Company’s board of directors, any replacement appointees will need to obtain unanimous approval from the remaining board members; and

(vi) Mayne Pharma waived its right to require the Company to obtain a written estimate from a contact research organization relating to the timing and completion of phase II trials on the use of the Product in the Field and waived its right to reasonably expect that the Product would launch by a date agreed upon the Company and Mayne.

Mayne Pharma may terminate the Agreement, as amended, if certain conditions (the “Conditions”) are not met by March 31, 2014. Such Conditions are summarized more fully in the Company’s Current Report on Form 8-K filed on September 10, 2013 (the “September 8-K”) and include conditions relating to a $5 million equity financing of the Company (or such lesser amount as may be approved by Mayne Pharma, the “Equity Financing”), the appointment of a representative to the board of directors of the Company, and Mayne Pharma’s acquisition of shares of the Company’s Series A Preferred Stock, representing, on an as fully converted, fully diluted basis, at least 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).
