THIS PLAN OF CONVERSION (this “Plan”), dated as of , 2016, is hereby adopted and approved by Viamet Pharmaceutical Holdings, LLC, a Delaware limited liability company (the “LLC”), in order to set forth the terms, conditions and procedures governing the conversion of the LLC into a Delaware corporation pursuant to Section 18-216 of the Delaware Limited Liability Company Act (as amended, the “LLC Act”) and Section 265 of the Delaware General Corporation Law (as amended, the “DGCL”).

WHEREAS, the LLC is a limited liability company formed and existing under the laws of the State of Delaware and is operating under the Viamet Pharmaceuticals Holdings, LLC Limited Liability Company Agreement (Fifth Amended and Restated) dated October 15, 2014, as amended (the “LLC Agreement”), by and among the LLC and the Members (as defined in the LLC Agreement, the “Members”);

WHEREAS, the Board (as defined in the LLC Agreement) and the Members have determined that it is in the best interests of the LLC for the LLC to convert into a Delaware corporation pursuant to Section 18-216 of the LLC Act and Section 265 of the DGCL upon the terms and conditions and in accordance with the procedures set forth herein, and the Board and the Members have authorized and approved the Conversion (as defined below) and the execution, delivery and filing of any and all instruments, certificates and documents necessary or desirable in connection therewith;

WHEREAS, the Conversion is intended to facilitate the initial public offering of Common Stock (as defined below) (the “Initial Public Offering”) pursuant to the registration statement on Form S-1 (the “Registration Statement”) filed by the LLC with the Securities and Exchange Commission; and

WHEREAS, pursuant to Section 8.1(a) of the LLC Agreement, upon the approval of (i) the Board (as defined in the LLC Agreement, the “Board”), including the vote of a majority of the Preferred Directors (as defined in the LLC Agreement, the “Preferred Directors”) and (ii) the Requisite Members (as defined in the LLC Agreement), the Board shall have authority to convert the LLC into a corporation.

NOW, THEREFORE, the LLC does hereby adopt this Plan to effectuate the conversion of the LLC into a Delaware corporation as follows:

1. Conversion; Effect of Conversion. Upon and subject to the terms and conditions of this Plan and pursuant to the relevant provisions of the LLC Act and the DGCL, including, without limitation, Section 18-216 of the LLC Act and Section 265 of the DGCL, respectively, the LLC shall convert (referred to herein as the “Conversion”) into a Delaware corporation named “Viamet Pharmaceuticals Corp.” (referred to herein as the “Corporation”) at the Effective Time (as defined below). The Corporation shall thereafter be subject to all of the provisions of the DGCL, except that notwithstanding Section 106 of the DGCL, the existence of the Corporation shall be deemed to have commenced on the date the LLC commenced (or is deemed to have commenced) its existence. The Conversion shall not affect any obligations or liabilities of the LLC incurred prior to the Effective Time. The LLC shall not be required to wind up its affairs or pay its liabilities and distribute its assets, and the Conversion shall not be deemed to constitute a dissolution of the LLC and shall constitute a continuation of the existence of the LLC in the form of a Delaware corporation. Upon the Effective Time, all of the rights, privileges and powers of the LLC, and all property and all debts due to the LLC, as well as all other things and causes of action belonging to the LLC, shall be vested in the Corporation and shall thereafter be the property of the Corporation as they were of the LLC, and all rights of creditors and all liens upon any property of the LLC shall be preserved unimpaired, and all debts, liabilities and duties of the LLC shall thereafter attach to the Corporation and may be enforced against it to the same extent as if such debts, liabilities and duties had been incurred or contracted by it.

2. Certificate of Conversion; Certificate of Incorporation; Effective Time. Upon approval of (i) the Board, including the vote of a majority of the Preferred Directors and (ii) the Requisite Members of this Plan, the Conversion shall be effected by the filing with the Secretary of State of Delaware of: (a) a duly executed Certificate of Conversion, substantially in the form of Exhibit A attached hereto (the “Certificate of Conversion”), and (b) a duly executed Certificate of Incorporation of the Corporation, in the form of Exhibit B attached hereto (the “Certificate of Incorporation”). Subject to the foregoing, the Conversion shall be effective immediately upon the filing of (i) the Certificate of Conversion and (ii) the Certificate of Incorporation with the Secretary of State of the State of Delaware (such time of effectiveness, the “Effective Time”), which time shall occur prior to the effectiveness of the Registration Statement.

3. Bylaws of the Corporation. From and after the Effective Time, the LLC Agreement shall terminate and no longer govern the affairs of the Corporation, but instead the affairs of the Corporation shall be conducted under the Bylaws of the Corporation, substantially in the form of Exhibit C attached hereto (the “Bylaws”), and the Certificate of Incorporation.

4. Directors and Officers. The directors and officers of the Corporation immediately after the Effective Time shall be those individuals who are set forth on Exhibit D attached hereto.

Notwithstanding the foregoing, the vesting schedule and other restrictions applicable to Incentive Shares (as defined in the LLC Agreement) issued pursuant to Award Agreements (as defined in the LLC Agreement) prior to the Effective Time shall continue to apply to shares of Common Stock issued in exchange for such Incentive Shares following the Effective Time (except, in the case of certain employees, any restrictions relating to continued employment), and each holder of Incentive Shares shall enter into a Restricted Stock Agreement that reflects such vesting schedule and restrictions.
