EXHIBIT A

ARTICLE I

The name of the corporation is LifeLock, Inc. (the “Corporation”).

ARTICLE II

The address of the Corporation’s registered office in the State of Delaware is 2711 Centerville Road, Suite 400, City of Wilmington, County of New Castle, Delaware 19808. The name of the Corporation’s registered agent at that address is Corporation Service Company.

ARTICLE III

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 (“DGCL”).

ARTICLE IV

A. Authorized Stock. The total number of shares of stock that the Corporation shall have authority to issue is 310,000,000, consisting of 300,000,000 shares of Common Stock, par value $0.001 per share (“Common Stock”), and 10,000,000 shares of Preferred Stock, par value $0.001 per share (“Preferred Stock”).

Immediately upon the acceptance of this Seventh Amended and Restated Certificate of Incorporation (the “Restated Certificate”) for filing by the Secretary of State of the State of Delaware (the “Effective Time”), each share of the Corporation’s voting common stock, par value $0.001 per share ( “Voting Common Stock”), issued and outstanding or held as treasury stock immediately prior to the Effective Time shall, automatically and without further action by any stockholder, be reclassified as, and shall become, one share of Common Stock. Any stock certificate that immediately prior to the Effective Time represented shares of the Corporation’s Voting Common Stock shall from and after the Effective Time be deemed to represent shares of Common Stock, without the need for surrender or exchange thereof.

B. Preferred Stock.

(1) The Board of Directors of the Corporation (the “Board of Directors”) is authorized, subject to any limitations prescribed by law, to provide for the issuance of shares of Preferred Stock in series, and by filing a certificate pursuant to the applicable law of the State of Delaware (such certificate being hereinafter referred to as a “Preferred Stock Designation”), to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences, and rights of the shares of each such series and any qualifications, limitations, or restrictions thereof.

(2) The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all of the outstanding shares of stock of the Corporation entitled to vote thereon, without a vote of the holders of the Preferred Stock, or of any series thereof, unless a vote of any such holders is required pursuant to the terms of any Preferred Stock Designation.

A-1

C. Voting Rights. Each holder of Common Stock, as such, shall be entitled to one vote for each share of Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote; 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 Restated Certificate (including any Preferred Stock Designation 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 of Preferred Stock to vote thereon pursuant to this Restated Certificate (including any Preferred Stock Designation relating to any series of Preferred Stock) or pursuant to the DGCL.

ARTICLE V

A. Board Size. Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the total number of authorized directors constituting the Board of Directors (the “Whole Board”) shall be fixed from time to time exclusively by the Board of Directors pursuant to a resolution adopted by a majority of the Whole Board.

B. Classified Board Structure. From and after the Effective Time, the directors, other than any who may be elected by the holders of any series of Preferred Stock under specified circumstances, shall be divided into three classes as nearly equal in size as is practicable, hereby designated Class I, Class II, and Class III. The Board of Directors may assign members of the Board of Directors already in office to such classes at the time such classification becomes effective. The term of office of the initial Class I directors shall expire at the first regularly scheduled annual meeting of the stockholders following the Effective Time, the term of office of the initial Class II directors shall expire at the second annual meeting of the stockholders following the Effective Time, and the term of office of the initial Class III directors shall expire at the third annual meeting of the stockholders following the Effective Time. At each annual meeting of stockholders, commencing with the first regularly scheduled annual meeting of stockholders following the Effective Time, each of the successors elected to replace the directors of a Class whose term shall have expired at such annual meeting shall be elected to hold office for a three year term and until the third annual meeting next succeeding his or her election and until his or her respective successor shall have been duly elected and qualified. Notwithstanding the foregoing provisions of this Article V, 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, any newly created directorships or decrease in directorships shall be so apportioned among the classes as to make all classes as nearly equal in number as is practicable, provided that no decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

C. Removal; Vacancies. Any director may be removed from office by the stockholders of the Corporation only for cause. Vacancies occurring on the Board of Directors 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 of Directors, although less than a quorum, or by a sole remaining director, at any meeting of the Board of Directors. A person elected to fill a vacancy or newly created directorship shall hold office until the 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 VI

The following provisions are inserted for the management of the business and the conduct of the affairs of the Corporation, and for further definition, limitation, and regulation of the powers of the Corporation and of its directors and stockholders:

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

B. Written Ballot. Elections of directors need not be by written ballot unless otherwise provided in the Bylaws of the Corporation.

C. Amendment of Bylaws. In furtherance and not in limitation of the powers conferred by the DGCL, the Board of Directors is expressly authorized to adopt, amend, or repeal the Bylaws of the Corporation. The stockholders may adopt, amend, or repeal the Bylaws of the Corporation only with the affirmative vote of the holders of not less than sixty-six and two-thirds percent (66-2/3%) of the total voting power of all outstanding securities of the Corporation then entitled to vote generally in the election of directors, voting together as a single class.

D. Special Meetings. Special meetings of the stockholders may be called only by (a) the Board of Directors pursuant to a resolution adopted by a majority of the Whole Board; (b) the chairperson of the Board of Directors; (c) the chief executive officer of the Corporation; or (d) the president of the Corporation (in the absence of a chief executive officer).

E. No Stockholder Action by Written Consent. Subject to the rights of the holders of any series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing by such stockholders.

F. No Cumulative Voting. No stockholder will be permitted to cumulate votes at any election of directors.

ARTICLE VII

A. Director Exculpation. To the fullest extent permitted by the DGCL, as the same exists or as may hereafter be amended, a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director except for liability (a) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL, or (d) for any transaction from which the director derived any improper personal benefit. If the DGCL is amended, after approval by the stockholders of this Article VII, to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

B. Indemnification. The Corporation shall have the power to indemnify to the fullest extent permitted by law any person made or threatened to be made a party to an action or proceeding, whether criminal, civil, administrative, or investigative, by reason of the fact that he or she, his or her testator or intestate is or was a director, officer, employee, or agent of the Corporation, any predecessor of the Corporation, or any subsidiary or affiliate of the Corporation, or serves or served at any other enterprise as a director, officer, employee, or agent at the request of the Corporation or any predecessor to the Corporation. The Corporation shall indemnify any person made or threatened to be made a party to an action or proceeding, whether criminal, civil, administrative, or investigative, by reason of the fact that he or she, his or her testator or intestate is or was a director or officer of the Corporation or any

A-3

predecessor of the Corporation, or serves or served at any other enterprise as a director or officer at the request of the Corporation, any predecessor to the Corporation, or any subsidiary or affiliate of the Corporation as and to the extent (and on the terms and subject to the conditions) set forth in the Bylaws of the Corporation or in any contract of indemnification entered into by the Corporation and any such person.

C. Vested Rights. Neither any amendment nor repeal of this Article VII, nor the adoption of any provision of this Restated Certificate inconsistent with this Article VII, shall eliminate or reduce the effect of this Article VII in respect of any matter occurring, or any action or proceeding accruing or arising or that, but for this Article VII, would accrue or arise, prior to such amendment, repeal, or adoption of an inconsistent provision.

ARTICLE VIII

Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Corporation, (b) 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, (c) any action asserting a claim against the Corporation arising pursuant to any provision of the DGCL, this Restated Certificate, or the Bylaws of the Corporation, or (d) any action asserting a claim against the Corporation governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article VIII.

ARTICLE IX

If any provision of this Restated Certificate becomes or is declared on any ground by a court of competent jurisdiction to be illegal, unenforceable, or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Restated Certificate, and the court will replace such illegal, void, or unenforceable provision of this Restated Certificate with a valid and enforceable provision that most accurately reflects the Corporation’s intent, in order to achieve, to the maximum extent possible, the same economic, business, and other purposes of the illegal, void, or unenforceable provision. The balance of this Restated Certificate shall be enforceable in accordance with its terms.

Except as provided in Article VII above, the Corporation reserves the right to amend, alter, change, or repeal any provision contained in this Restated Certificate, in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this reservation; provided, however, that, notwithstanding any other provision of this Restated Certificate or any provision of law that might otherwise permit a lesser vote or no vote, but in addition to any vote of the holders of any class or series of the stock of this Corporation required by law or by this Restated Certificate, the affirmative vote of the holders of not less than sixty-six and two-thirds percent (66-2/3%) of the total voting power of all outstanding securities of the Corporation then entitled to vote generally in the election of directors, voting together as a single class, shall be required to amend or repeal, or adopt any provision of this Restated Certificate inconsistent with, Article IV(C), Article V, Article VI, Article VII, Article VIII, or this Article IX.
