AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

OF

ADEPTUS HEALTH INC.

The present name of the corporation is Adeptus Health Inc. (the “Corporation”).  The Corporation was incorporated under the name “Adeptus Health Inc.” by the filing of its original certificate of incorporation (the “Original Certificate of Incorporation”) with the Secretary of State of the State of Delaware on March 7, 2014.  This Amended and Restated Certificate of Incorporation of the Corporation, which both restates and amends the provisions of the Original Certificate of Incorporation, was duly adopted in accordance with the provisions of Sections 242 and 245 of the General Corporation Law of the State of Delaware.  The Original Certificate of Incorporation of the Corporation is hereby amended and restated to read in its entirety as follows:

ARTICLE I

Section 1.1.                                 Name.  The name of the Corporation is Adeptus Health Inc.

ARTICLE II

Section 2.1.                                 Address.  The address of the registered office of the Corporation in the State of Delaware is 1209 Orange Street, in the City of Wilmington, County of New Castle, Delaware 19801; and the name of the Corporation’s registered agent at such address is The Corporation Trust Company.

ARTICLE III

Section 3.1.                                 Purpose.  The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”).

ARTICLE IV

Section 4.1.                                 Capitalization.  The total number of shares of all classes of stock that the Corporation is authorized to issue is 80,000,000 shares of stock, consisting of (i) 10,000,000 shares of Preferred Stock, par value $0.01 per share (“Preferred Stock”), (ii) 50,000,000 shares of Class A Common Stock, par value $0.01 per share (“Class A Common Stock”), and (iii) 20,000,000 shares of Class B Common Stock, par value $0.01 per share (“Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”).  Subject to the rights of the holders of any shares of Preferred Stock, the number of authorized shares of any of the Class A Common Stock and Class B Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of at least 662/3% in voting power of the outstanding stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of any of the Class A Common Stock, Class B Common Stock or Preferred Stock voting separately as a class shall be required therefor.

Upon this Amended and Restated Certificate of Incorporation becoming effective pursuant to the DGCL (the “Effective Time”), each share of the Corporation’s common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time, will be automatically reclassified as and converted into one share of Class A Common Stock.

Section 4.2.                                 Preferred Stock.

(A)                               The Board of Directors of the Corporation (the “Board”) is hereby expressly authorized, by resolution or resolutions, to provide one or more series of Preferred Stock (including convertible preferred stock) and, with respect to each such series, to fix the number of shares constituting such series and the designation of such series, the voting powers (if any) of the shares of such series, and the powers, preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series.  The powers, preferences and relative, participating, optional and other special rights of each series of Preferred Stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding.

(B)                               Except as otherwise required by law, holders of a series of Preferred Stock, as such, shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to such series).

Section 4.3.                                 Common Stock.

(A)                               Voting Rights.

(1)                                 Each holder of Class A Common Stock, as such, shall be entitled to one vote for each share of Class A Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote; provided, however, that to the fullest extent permitted by law, holders of Class A Common Stock, as such, shall have no voting power with respect to, and shall not be entitled to vote on, any amendment to this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if only the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) or pursuant to the DGCL.

(2)                                 Each holder of Class B Common Stock, as such, shall be entitled to one vote for each share of Class B Common Stock held of record by such holder on all matters on which stockholders are generally entitled to vote; provided, however, that to the fullest extent permitted by law, holders of Class B Common Stock, as such, shall have no voting power with respect to, and shall not be entitled to vote on, any amendment to this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) that relates solely to the terms of

2

one or more outstanding series of Preferred Stock if only the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) or pursuant to the DGCL.

(3)                                 Except as otherwise required in this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) or by applicable law, the holders of Common Stock shall vote together as a single class on all matters (or, if any holders of Preferred Stock are entitled to vote together with the holders of Common Stock, as a single class with such holders of Preferred Stock).

(B)                               Dividends; Stock Splits or Combinations.

(1)                                 Subject to applicable law and the rights, if any, of the holders of any outstanding series of Preferred Stock or any class or series of stock having a preference over or the right to participate with the Class A Common Stock with respect to the payment of dividends, dividends may be declared and paid on the Class A Common Stock out of the assets of the Corporation that are by law available therefor, at such times and in such amounts as the Board in its discretion shall determine.

(2)                                 In no event shall any stock split, reverse stock split, combination of stock, reclassification or recapitalization be declared or made on any outstanding class of Common Stock of the Corporation unless contemporaneously therewith the shares of any other class of Common Stock of the Corporation and the LLC Units at the time outstanding are treated in the same proportion and the same manner.

(3)                                 In no event shall any cash or stock dividends or distributions be declared or made on Class A Common Stock unless the shares of Class A Common Stock at the time outstanding are treated equally and such cash or stock dividend or distribution is declared or made in the same economically equivalent manner on all LLC Units.

(4)                                 Cash or stock dividends or distributions may not be declared or paid on the Class B Common Stock.

(C)                               Liquidation, Dissolution or Winding Up.  In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, after payment or provision for payment of the debts and other liabilities of the Corporation and of the preferential and other amounts, if any, to which the holders of Preferred Stock shall be entitled, the holders of all outstanding shares of Class A Common Stock shall be entitled to receive the remaining assets of the Corporation available for distribution ratably in proportion to the number of shares held by each such stockholder.  Without limiting the rights of the holders of Class B Common Stock to exchange their shares of Class B Common Stock and LLC Units for shares of Class A Common Stock in accordance with Section 3.6 of the Amended and Restated Limited Liability Company Agreement (or for the consideration payable in respect of shares of Class A Common Stock in such voluntary or involuntary liquidation, dissolution or winding up), the

3

holders of shares of Class B Common Stock, as such, shall not be entitled to receive any assets of the Corporation in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation.

(D)                               Cancellation of Class B Common Stock.  Immediately upon the exchange of an LLC Unit (together with a share of Class B Common Stock) for Class A Common Stock pursuant to the terms of the Amended and Restated Limited Liability Company Agreement and Article V hereof, such share of Class B Common Stock held by such exchanging holder of LLC Units shall automatically be canceled with no consideration being paid or issued with respect thereto.  Any such canceled shares of Class B Common Stock shall no longer be outstanding and all rights with respect to such shares shall automatically cease and terminate.

(E)                                Shares Reserved for Issuance.  The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of (1) Class A Common Stock, such number of shares of Class A Common Stock that shall from time to time be sufficient to effect the exchange of all outstanding LLC Units (along with Class B Common Stock) for Class A Common Stock; provided, that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of the exchange of the LLC Units (along with Class B Common Stock) by delivery of purchased shares of Class A Common Stock which are held in the treasury of the Corporation.

ARTICLE V

Section 5.1.                                 Exchange of LLC Units.  Each holder of a LLC Unit shall be entitled to exchange such holder’s LLC Units (along with a corresponding number of shares of Class B Common Stock, as applicable) for shares of Class A Common Stock, in each case pursuant to, and solely as provided in, the Amended and Restated Limited Liability Company Agreement.

Section 5.2.                                 Amendment of Article V.  Notwithstanding anything to the contrary contained in this Amended and Restated Certificate of Incorporation, and in addition to any other vote required by the DGCL or this Amended and Restated Certificate of Incorporation, the affirmative vote of the holders of at least 662/3% in voting power of the then outstanding Class B Common Stock, voting together as a class, shall be required to alter, amend or repeal this Article V or to adopt any provision inconsistent therewith.
