Capital Stock

1. Authorized Stock. Prior to the filing of this Certificate of Incorporation, the Corporation was a Cayman Islands exempted company (at such time, the “Predecessor Corporation”), which had authorized share capital consisting of 1,000,000 Preferred Shares, par value $0.0001 per share (“Predecessor Preferred Shares”), 380,000,000 Class A Ordinary Shares, par value $0.0001 per share (the “Predecessor Class A Ordinary Shares”) and 20,000,000 Class B Ordinary Shares, par value $0.0001 per share (the “Predecessor Class B Ordinary Shares”). Immediately upon the acceptance of this Certificate of Incorporation for filing by the Secretary of State of the State of Delaware, each one (1) Predecessor Class B Ordinary Share automatically, without any further action, converted into an equal number of Predecessor Class A Ordinary Shares. Immediately following the conversion of Predecessor Class B Ordinary Shares into Predecessor Class A Ordinary Shares, the Predecessor Class A Ordinary Shares issued and outstanding or held as treasury stock, automatically and without further action by any stockholder, were reclassified as, and became, shares of Class A Common Stock (as defined below). As a result, the total number of shares of all classes of stock that the Corporation is authorized to issue is 501,000,000 shares of stock, consisting of (a) 1,000,000 shares of Preferred Stock, par value $0.0001 per share (“Preferred Stock”), (b) 500,000,000 shares of common stock (“Common Stock”), including (i) 400,000,000 shares of Class A common stock, par value $0.0001 (“Class A Common Stock”) and (ii) 100,000,000 shares of Class B common stock, par value $0.0001 (“Class B Common Stock”). Each share of Common Stock shall entitle the holder hereof to one (1) vote on each matter submitted to a vote at a meeting of stockholders.

1

2.  Preferred Stock   Preferred Stock may be issued from time to time in one or more series pursuant to a resolution or resolutions providing for such issue duly adopted by the Board of Directors of the Corporation (the “Board”), authority to do so being hereby expressly vested in the Board. The Board is further authorized, subject to limitations prescribed by law, to fix by resolution or resolutions the designations, powers, preferences and rights, and the qualifications, limitations or restrictions thereof, of any wholly unissued series of Preferred Stock, including without limitation authority to fix by resolution or resolutions the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and liquidation preferences of any such series, and the number of shares constituting any such series and the designation thereof, or any of the foregoing.

3. Common Stock.

(a) Except as otherwise required by law or this Certificate, the holders of the Common Stock shall possess all voting power with respect to the Corporation. The holders of shares of Common Stock shall be entitled to one vote for each such share on each matter properly submitted to the stockholders on which the holders of the Common Stock are entitled to vote. The holders of shares of Class A Common Stock and Class B Common Stock shall at all times vote together as one class on all matters submitted to a vote of the stockholders of the Corporation.

(b) Except as otherwise required by law or this Certificate, at any annual or special meeting of the stockholders of the Corporation, the holders of the Common Stock shall have the exclusive right to vote for the election of directors and on all other matters properly submitted to a vote of the stockholders.

(c) Subject to the rights, if any, of the holders of any outstanding series of the Preferred Stock, the holders of the Common Stock shall be entitled to receive such dividends and other distributions (payable in cash, property or capital stock of the Corporation) when, as and if declared thereon by the Board from time to time out of any assets or funds of the Corporation legally available therefor, and shall share equally on a per share basis in such dividends and distributions; provided, however, that the holders of Class B Common Stock shall not be entitled to share in any such dividends or other distributions.

(d) Subject to the rights, if any, of the holders of any outstanding series of the Preferred Stock, in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation, after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of the Common Stock shall be entitled to receive all the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of the Common Stock held by them; provided, however, that the holders of Class B Common Stock shall not be entitled to receive any portion of any such assets in respect of their shares of Class B Common Stock.

4. Class B Common Stock.

(a) Shares of Class B Common Stock may only be issued to and held by Algeco Scotsman Global S.à r.l., a Luxembourg société à responsabilité limitée (“Algeco Global”) and Algeco Scotsman Holdings Kft., a Hungarian limited liability company (together with Algeco Global, the “Sellers”) and their respective Permitted Transferees (as defined in the Exchange Agreement, dated as of November 29, 2017, by and among the Corporation, the Sellers, and the Holdco Acquiror (as defined below) (the “Exchange Agreement”)) and any other transferee of shares of common stock of Williams Scotsman Holdings Corp. (the “Holdco Acquiror”) to the extent permitted by the Exchange Agreement (collectively, the “Permitted Holders”).

(b) At any time the Holdco Acquiror issues a share of its common stock to a Permitted Holder, the corporation shall issue a share of Class B Common Stock to such Permitted Holder. Upon the conversion or cancellation of any share of the Holdco Shares pursuant to the Exchange Agreement, the corresponding share of Class B Common Stock automatically shall be cancelled for no consideration being paid or issued with respect thereto and without any action on the part of any person, including the Corporation, subject to the terms of the Exchange Agreement. Any such cancelled shares of Class B Common Stock shall be deemed no longer outstanding, and all rights with respect to such shares shall automatically cease and terminate. Shares of Class B Common Stock may only be transferred to a person other than the Corporation if the transferee is a Permitted Holder and an equal number of shares of the Holdco Shares are simultaneously transferred to such transferee in accordance with the

2

Exchange Agreement. If shares of the Holdco Shares are being transferred to a Permitted Holder in accordance with the Exchange Agreement, an equal number of shares of Class B Common Stock must be simultaneously transferred to such transferee. The Corporation shall take all actions necessary so that, for so long as the Class B Common Stock is outstanding, the number of shares of Class B Common Stock outstanding equals the number of shares of the Holdco Shares outstanding and held by the Permitted Holders. For the avoidance of doubt, nothing herein restricts the ability of the Permitted Holders from surrendering shares of Class B Common Stock to the Corporation pursuant to the Exchange Agreement.

(c) The Corporation shall, and shall cause the Holdco Acquiror to, take all actions necessary so that, for as long as the Class B Common Stock is outstanding, the number of shares of the Holdco Shares outstanding equals the number of shares of Class B Common Stock outstanding. The Corporation shall take all such other actions as may be reasonably necessary or advisable to give effect to the intended substantive economic results of the provisions of this Certificate and the Exchange Agreement.

(d) At any time when there are no longer any shares of Class B Common Stock outstanding, this Certificate automatically shall be deemed amended to delete this Section 5.4 in its entirety.

ARTICLE VI

Bylaws

In furtherance and not in limitation of the powers conferred by statute, the Board shall have the power to adopt, amend, repeal or otherwise alter the bylaws of the Corporation (the “Bylaws”) without any action on the part of the stockholders; provided, however, that any Bylaws made by the Board may be amended, altered or repealed by the stockholders.

ARTICLE VII

Directors

1. Board of Directors. The business and affairs of the Corporation shall be managed by or under the direction of the Board. In addition to the powers and authority expressly conferred upon them by statute or by this Certificate of Incorporation or the Bylaws, the directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation.

2. Number; Term; Election; Qualification. The number of directors that constitutes the initial Board is seven and shall be fixed from time to time by resolution of the Board in accordance with the Bylaws. The Board shall be divided into three classes designated Class I, Class II and Class III. The number of directors elected to each class shall be as nearly equal in number as possible. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the Board. Each Class I director shall be elected to an initial term to expire at the first annual meeting of stockholders following effectiveness of this Certificate of Incorporation, each Class II director shall be elected to an initial term to expire at the second annual meeting of stockholders following effectiveness of this Certificate of Incorporation and each Class III director shall be elected to an initial term to expire at the third annual meeting of stockholders following effectiveness of this Certificate of Incorporation. Upon the expiration of the initial terms of office for each class of directors, the directors of each class shall be elected for a term of three years to serve until their successors have been duly elected and qualified or until their earlier resignation or removal, except that if any such election shall not be so held, such election shall take place at a stockholders’ meeting called and held in accordance with the DGCL.  Each director shall serve until his or her successor is duly elected and qualified or until his or her death, resignation, or removal. If the number of directors is hereafter changed, no decrease in the number of directors constituting the Board shall shorten the term of any incumbent director.

3. Removal and Vacancies. Vacancies occurring on the Board for any reason and newly created directorships resulting from an increase in the authorized number of directors may be filled only by vote of a majority of the remaining members of the Board, although less than a quorum, or by a sole remaining director, at any meeting of the Board. A person so elected by the Board to fill a vacancy or newly created directorship shall hold office until the

3

next election of the class for which such director shall have been chosen and until his or her successor shall be duly elected and qualified.

ARTICLE VIII

Indemnification of Directors

1. Limitation of Liability. A director of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended. If the DGCL is hereafter amended to authorize corporate action further limiting or eliminating the personal liability of directors, then the liability of each current or former director or officer of the Corporation shall be limited or eliminated to the fullest extent permitted by the DGCL as so amended from time to time. Neither any amendment nor repeal of this Article VIII, nor the adoption of any provision of this Certificate of Incorporation inconsistent with this Article VIII, shall eliminate or reduce the effect of this Article VIII in respect of any matter occurring, or any cause of action, suit or claim that, but for this Article VIII, would accrue or arise, prior to such amendment, repeal or adoption of an inconsistent provision.

2. Indemnification. The Corporation shall, in accordance with this Certificate of Incorporation and the Bylaws, indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) (a “proceeding”), by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee, member, trustee, partner, representative or agent of another corporation, partnership, limited liability company, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans maintained or sponsored by the Corporation (an “indemnitee”), against all expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee. The Corporation shall be required to indemnify an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if the initiation of such proceeding (or part thereof) by the indemnitee was authorized by the Board. Each person who was, is or becomes a director or officer of the Corporation shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Article VIII. All rights to indemnification under this Article VIII shall be deemed to have vested at the time such person becomes or became a director or officer of the Corporation, and such rights shall continue as to an indemnitee who has ceased to be a director and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Any amendment, modification, alteration or repeal of this Article VIII that in any way diminishes, limits, restricts, adversely affects or eliminates any right of an indemnitee or his or her successors to indemnification, advancement of expenses or otherwise shall be prospective only and shall not in any way diminish, limit, restrict, adversely affect or eliminate any such right with respect to any actual or alleged state of facts, occurrence, action or omission then or previously existing, or any action, suit or proceeding previously or thereafter brought or threatened based in whole or in part upon any such actual or alleged state of facts, occurrence, action or omission. Claims for indemnification shall be made pursuant to the procedural requirements of the Bylaws.

3. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

ARTICLE IX

Exclusive Jurisdiction for Certain Actions

1. Exclusive Forum. Unless the Board or one of its committees otherwise approves, in accordance with

4

Section 141 of the DGCL, this Certificate of Incorporation and the Bylaws, to the selection of an alternate forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware does not have jurisdiction, the Superior Court of the State of Delaware, or, if the Superior Court of the State of Delaware also does not have jurisdiction, the United States District Court for the District of Delaware) shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation arising pursuant to any provision of the DGCL or this Certificate of Incorporation or the Bylaws, (iv) any action to interpret, apply, enforce or determine the validity of this Certificate of Incorporation or the Bylaws or (v) any action asserting a claim against the Corporation governed by the internal affairs doctrine (each, a “Covered Proceeding”).

2. Personal Jurisdiction. If any action the subject matter of which is a Covered Proceeding is filed in a court other than the Court of Chancery of the State of Delaware, or, where permitted in accordance with paragraph (a) above, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, (each, a “Foreign Action”) in the name of any person or entity (a “Claiming Party”) without the prior approval of the Board or one of its committees in the manner described in paragraph (a) above, such Claiming Party shall be deemed to have consented to (i) the personal jurisdiction of the Court of Chancery of the State of Delaware, or, where applicable, the Superior Court of the State of Delaware and the United States District Court for the District of Delaware, in connection with any action brought in any such courts to enforce paragraph (a) above (an “Enforcement Action”) and (ii) having service of process made upon such Claiming Party in any such Enforcement Action by service upon such Claiming Party’s counsel in the Foreign Action as agent for such Claiming Party.

3. Notice and Consent. Any person or entity purchasing or otherwise acquiring any interest in the shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article IX and waived any argument relating to the inconvenience of the forums reference above in connection with any Covered Proceeding.

ARTICLE X

Severability

If any provision or provisions of this Certificate of Incorporation shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Certificate of Incorporation (including, without limitation, each portion of any paragraph of this Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (ii) to the fullest extent possible, the provisions of this Certificate of Incorporation (including, without limitation, each such portion of any paragraph of this Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.

ARTICLE XI

Corporate Opportunity

The doctrine of corporate opportunity, or any other analogous doctrine, shall not apply with respect to the Corporation or any of its non-employee directors, or any of their affiliates, in circumstances where the application of any such doctrine would conflict with any fiduciary duties or contractual obligations they may have as of the date of this Certificate of Incorporation or in the future. In addition to the foregoing, the doctrine of corporate opportunity shall not apply to any other corporate opportunity with respect to any of the non-employee directors of the Corporation unless such corporate opportunity is offered to such person solely in his or her capacity as a director of the Corporation and such opportunity is one the Corporation is legally and contractually permitted to undertake and would otherwise be reasonable for the Corporation to pursue.

ARTICLE XII

Amendment
