ARTICLE THREE

The nature of the business 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 FOUR

Section 1. Authorized Shares. The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is 350,000,000 shares, consisting of:

(a) 50,000,000 shares of Preferred Stock, par value $0.01 per share (the “Preferred Stock”); and

(b) 300,000,000 shares of Common Stock, par value $0.01 per share (the “Common Stock”).

The Preferred Stock and the Common Stock shall have the rights, preferences and limitations set forth below.

Section 2. Preferred Stock. The Board of Directors is authorized, subject to limitations prescribed by law, to provide, by resolution or resolutions for the issuance of shares of Preferred Stock in one or more series, and with respect to each series, to establish the number of shares to be included in each such series, and to fix the voting powers (if any), designations, powers, preferences, and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, limitations or restrictions thereof. 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. Subject to applicable law and within the limitations or restrictions stated in any resolution or resolutions of the Board of Directors fixing the number of shares constituting a series of Preferred Stock, the Board of Directors may increase or decrease (but not below the number of shares of any such series of Preferred Stock then outstanding and not above the total number of authorized shares of Preferred Stock) by resolution the number of shares of any such series of Preferred Stock. In the event that the number of shares of any series of Preferred Stock shall be so decreased, the shares constituting such decrease shall resume the undesignated status which such shares had prior to the adoption of the resolution originally fixing the number of shares of such series of Preferred Stock subject to the requirements of applicable law. In addition, the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by approval of the Board of Directors and

by the affirmative vote of the holders of a majority in voting power of the outstanding shares of capital stock of the Corporation entitled to vote generally in an election of directors, without the separate vote of the holders of the Preferred Stock as a class, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Section 3. Common Stock.

(a) Except as otherwise provided by the DGCL or this Certificate of Incorporation and subject to the rights of holders of any series of Preferred Stock, all of the voting power of the stockholders of the Corporation shall be vested in the holders of the Common Stock. Each share of Common Stock shall entitle the holder thereof to one vote for each share held by such holder on all matters voted upon by the stockholders of the Corporation; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this 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 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 Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock).

(b) Except as otherwise required by law or expressly provided in this Certificate of Incorporation, each share of Common Stock shall have the same powers, rights and privileges and shall rank equally, share ratably and be identical in all respects as to all matters.

(c) Subject to the rights of the holders of Preferred Stock and to the other provisions of this Certificate of Incorporation, holders of Common Stock shall be entitled to receive equally, on a per share basis, such dividends and other distributions in cash, securities or other property of the Corporation as may be declared thereon by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor.

(d) In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, after payment or provision for payment of the Corporation’s debts and any other payments required by law and amounts payable upon shares of Preferred Stock ranking senior to the shares of Common Stock upon such dissolution, liquidation or winding up, if any, the remaining net assets of the Corporation shall be distributed to the holders of shares of Common Stock and the holders of shares of any other class or series ranking equally with the shares of Common Stock upon such dissolution, liquidation or winding up, equally on a per share basis. A merger or consolidation of the Corporation with or into any other corporation or other entity, or a sale or conveyance of all or any part of the assets of the Corporation (which shall not in fact result in the liquidation of the Corporation and the distribution of assets to its stockholders) shall not be deemed to be a voluntary or involuntary liquidation or dissolution or winding up of the Corporation within the meaning of this Paragraph (d).

ARTICLE FIVE

The Corporation is to have perpetual existence.

ARTICLE SIX

Section 1. Board of Directors. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

The directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting of the stockholders and entitled to vote in the election of directors; provided that, whenever the holders of any class or series of capital stock of the Corporation are entitled to elect one or more directors pursuant to the provisions of this Certificate of Incorporation (including, but not limited to, any duly authorized certificate of designation), such directors shall be elected by a plurality of the votes of such class or series present in person or represented by proxy at the meeting of the stockholders and entitled to vote in the election of such directors. At each annual meeting of stockholders, directors elected to replace those of a Class whose terms expire at such annual meeting shall be elected to hold office until the third succeeding annual meeting after their election and until their respective successors shall have been duly elected and qualified. Each director shall hold office until the annual meeting of stockholders for the year in which such director’s term expires and a successor is duly elected and qualified or until his or her earlier death, resignation or removal. Nothing in this Certificate of Incorporation shall preclude a director from serving consecutive terms.

A director chosen to fill a position resulting from an increase in the number of directors shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor is elected and qualified, or until his or her earlier death, resignation or removal. No decrease in the authorized number of directors shall shorten the term of any incumbent director. “Stock Director” means any director originally designated by Stock Building Supply Holdings, Inc., or any successor to such director whose nomination and election was approved by a Stock Director.

(b) Prior to the date of the 2017 annual meeting of stockholders, the chairman of the Audit Committee of the Board of Directors may be appointed only by resolution of a majority of the directors then in office, including at least one Stock Director.

(b) Any amendment, repeal or modification of the foregoing paragraph shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification with respect to any act, omission or other matter occurring prior to such amendment, repeal or modification.
