Delaware Code
     The Company is incorporated under the laws of the State of Delaware. Section 145 (“Section 145”) of Title 8 of the Delaware Code gives a corporation power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.
     Section 145 also gives a corporation power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper. Section 145 further provides that, to the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any such action, suit or proceeding, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.
     Section 145 provides that expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it is ultimately determined that such person is not entitled to be indemnified by the corporation as authorized by Section 145. Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.
     Section 145 also authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, arising out of such person’s status as such, whether or not the corporation would otherwise have the power to indemnify such person against such liability under Section 145.

     The above discussion of Section 145 is not intended to be exhaustive and is qualified in its entirety by such statute.
Amended Bylaws
     The Company’s Amended Bylaws (the “Bylaws”) provide for the indemnification of its officers, directors, employees and agents and the advancement to them of expenses in connection with actions, suits or proceedings, to the fullest extent permitted by law. The indemnification and advancement of expenses provided by the Company’s Bylaws is not exclusive of any other rights to which those seeking indemnification or advancement of expenses may be or become entitled under any law, the Company’s Certificate of Incorporation, the Company’s Bylaws, agreement, the vote of stockholders or disinterested directors or otherwise, or under any policy or policies of insurance purchased and maintained by the Company on behalf of any such person, both as to action in his official capacity and as to action in another capacity while holding such office.
     The indemnification provided by the Company’s Bylaws is subject to all valid and applicable laws, and, in the event the Company’s Bylaws or any of the provisions thereof or the indemnification contemplated thereby are found to be inconsistent with or contrary to any such valid laws, the latter shall be deemed to control and the Company’s Bylaws shall be regarded as modified accordingly, and, as so modified, to continue in full force and effect. The indemnification and advancement of expenses provided by the Company’s Bylaws continues as to any person who has ceased to be a director, officer, employee or agent of the Company and will inure to the benefit of the estate, executors, administrators, heirs, legatees and devisees of any person entitled to indemnification under the Company’s Bylaws.
     The above discussion of the Company’s Bylaws is not intended to be exhaustive and is qualified in its entirety by the Bylaws.
Insurance
     All of the Company’s directors and officers will be covered by insurance policies maintained by the Company against certain liabilities for actions taken in their capacities as such, including liabilities under the Securities Act of 1933, as amended.

Item 9. Undertakings.
     (a) The Company hereby undertakes:
     (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
     (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
     (ii) To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) of the Securities Act of 1933 if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
     (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;
provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement.
     (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
     (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
     (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of

4


Table of Contents

the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
     (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 6 above, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:
     As set forth in the Registration Statement on Form S-8 (the “Registration Statement”) to be filed by Administaff, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), relating to the issuance of 1,500,000 shares (the “Shares”) of common stock, par value $.01 per share, of the Company pursuant to the Company’s 2008 Employee Stock Purchase Plan (as amended, the “Plan”), certain legal matters with respect to the Shares are being passed upon for the Company by us. At your request, this opinion is being furnished to you for filing as Exhibit 5.1 to the Registration Statement.
     We have examined originals, or copies certified or otherwise identified, of the Certificate of Incorporation and Bylaws of the Company, each as amended to date, the Plan, corporate records of the Company, including minute books of the Company, as furnished to us by the Company, certificates of public officials and of representatives of the Company, statutes and other instruments and documents as a basis for the opinions hereinafter expressed. In giving such opinions, we have relied upon certificates of officers of the Company and of public officials with respect to the accuracy of the material factual matters contained in such certificates. In giving the opinions below, we have assumed that the signatures on all documents examined by us are genuine, that all documents submitted to us as originals are accurate and complete, that all documents submitted to us as copies are true and correct copies of the originals thereof and that all information submitted to us was accurate and complete. In addition, we have assumed for purposes of this opinion that the consideration received by the Company for the Shares will be not less than the par value of the Shares.
     On the basis of the foregoing, and subject to the assumptions, limitations and qualifications set forth herein, we are of the opinion that the Shares have been duly authorized and, when issued and delivered against payment of the purchase price thereof in accordance with the terms and provisions of the Plan, will be validly issued, fully paid and nonassessable.
     The opinions set forth above are limited in all respects to matters of the General Corporation Law of the State of Delaware.
     We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. In giving such consent, we do not admit that we are in the

ADMINISTAFF, INC.
2008 EMPLOYEE STOCK PURCHASE PLAN
SECTION 1 . ESTABLISHMENT OF THE PLAN .
     The Administaff, Inc. 2008 Employee Stock Purchase Plan (the “Plan”) is hereby established to provide Eligible Employees with an opportunity to increase their proprietary interest in the success of the Company by purchasing Stock from the Company on favorable terms and to pay for such purchases through payroll deductions. The Plan is intended to qualify for favorable tax treatment under section 423 of the Code.
SECTION 2 . DEFINITIONS .
     When used herein the following terms shall have the following meanings solely for purposes of the Plan:
     (a)  “Administrator” means the Compensation Committee of the Board of Directors of the Company or such other individual or individuals appointed by the Board or the Committee from time to time to act as Administrator.
     (b) “ Board ” means the Board of Directors of the Company.
     (c) “ Code ” means the Internal Revenue Code of 1986, as amended.
     (d) “ Company ” means Administaff, Inc., a Delaware corporation.
     (e) “ Committee ” means the Compensation Committee of the Board.
     (f) “ Compensation ” means the amount of compensation paid to an Eligible Employee by a Participating Company as salary, wages or other amounts paid for personal services actually rendered in the course of employment with the Participating Company to the extent includable in gross income of the Eligible Employee, increased by amounts described in sections 125, 132, 401(k) and 402A of the Code but excluding (a) contributions to and distributions from a plan of deferred compensation, regardless of whether such amounts are includible in the gross income of the Eligible Employee when contributed or distributed (as applicable); (b) amounts realized as a result of participation in a Participating Company’s long-term incentive programs including, without limitation, the exercise of stock options and upon the vesting of restricted stock; (c) other amounts which receive special tax benefits, such as premiums for group-term life insurance, (whether or not the contributions are excludable from the gross income of the Eligible Employee); and (d) reimbursements or other expense allowances, fringe benefits (cash or non-cash), moving expenses and welfare benefits. The Administrator shall determine whether a particular item is included in Compensation and shall have the authority to amend the definition of Compensation from time to time as it deems appropriate.

     (b) Following the purchase of the shares, the shares will be credited in book entry form as soon as practicable after each purchase date to an account administered by a designated custodian which is a brokerage firm, bank or financial institution, to be held for the benefit of the Participant. A Participant may, at any time, in such form and manner as established by the custodian, direct the custodian to deliver to the Participant all or part of the shares held by the custodian in his or her account or to sell such shares and deliver to the Participant the proceeds therefrom, less applicable expenses; provided, however, that the Administrator may establish procedures to permit tracking of disqualifying dispositions of the shares.
     (c) In the event that the aggregate number of shares which all Participants elect to purchase during an Offering Period shall exceed the number of shares remaining available for issuance under the Plan, then the number of shares to which each Participant shall become entitled shall be determined by multiplying the number of shares available for issuance by a fraction. The numerator of such fraction is the number of shares the Participant has elected to purchase pursuant to Section 5. The denominator of such fraction is the number of shares that all Participants have elected to purchase pursuant to Section 5. Any cash amount remaining in the Participant’s Plan Account under these circumstances shall be distributed to the Participant.
     (d) An amount remaining in the Participant’s Plan Account that represents the purchase price for any fractional share shall be carried over in the Participant’s Plan Account to the next Offering Period. Any amount remaining in the Participant’s Plan Account for any other reason shall be refunded to the Participant in cash, without interest.
     (e) As soon as practicable following the end of each Offering Period, the Company shall deliver to each Participant a Plan Account statement setting forth the amount of payroll deductions, the purchase price, the number of shares purchased and the remaining cash balance, if any.
     (f) Any other provision of the Plan notwithstanding, no shares of Stock shall be purchased under the Plan unless and until the Company’s stockholders have approved the adoption of the Plan.
SECTION 10 . WITHDRAWAL FROM THE PLAN .
     A Participant may elect to withdraw from participation under the Plan at any time up to the fifteenth day of the last month of an Offering Period (or such other date specified by the Administrator) by following the procedures prescribed by the Administrator. As soon as administratively practicable after a withdrawal, payroll deductions shall cease and all amounts credited to the Participant’s Plan Account will be distributed to the Participant in cash, without interest. No partial withdrawals shall be permitted. A Participant who has withdrawn from the Plan shall not be a Participant in future Offering Periods, unless he or she again enrolls in accordance with the provisions of Section 5 and re-enrollment may be effective only at the commencement of an Offering Period.

Any adjustments under this Section 13(a) will be made in accordance with the requirements of sections 423 and 409A of the Code.

SECTION 14 . LIMITATION ON STOCK OWNERSHIP .
     (a) Any other provision of the Plan notwithstanding, no Participant shall be granted a right to purchase Stock under the Plan if such Participant, immediately after his or her election to purchase such Stock, would own stock possessing more than 5% of the total combined voting power or value of all classes of stock of the Company or any Subsidiary of the Company. For purposes of this Section 14(a), the following rules shall apply:

     (b) Shares of Stock shall not be issued under the Plan unless the issuance and delivery of such shares comply with (or are exempt from) all applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state securities laws and regulations, and the regulations of any stock exchange or other securities market on which the Company’s securities may then be traded.
