ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Provision for indemnification of directors and officers is made in Section 145 of the Delaware General Corporation Law.

Article Fifth, Sections 3 and 4 of the ADP's Amended and Restated Certificate of Incorporation provide as follows:

"The Corporation shall indemnify all directors and officers of the Corporation to the full extent permitted by the General Corporation Law of the State of Delaware (and in particular Paragraph 145 thereof), as from time to time amended, and may purchase and maintain insurance on behalf of such directors and officers. In addition, the Corporation shall, in the manner and to the extent as the Bylaws of the Corporation shall provide, indemnify to the full extent permitted by the General Corporation Law of the State of Delaware (and in particular Paragraph 145 thereof), as from time to time amended, such other persons as the By-laws shall provide, and may purchase and maintain insurance on behalf of such other persons."

"A director of the Corporation shall not be held personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director; except for liability (i) for breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware, or (iv) for any transaction from which the director derived an improper personal benefit. Any repeal or modification of this paragraph by the stockholders of the Corporation shall not adversely affect any right or protection of any director of the Corporation existing at the time of, or for or with respect to any acts or omissions occurring prior to, such repeal or modification."

Finally, Article 6, Section 6.01 of ADP's By-Laws provides as follows:

"Nature of Indemnity: The Corporation shall 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, by reason of the fact that he or she is or was or has agreed to become a director or officer of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as a director or officer, of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, and may indemnify any person who was or is a party or is threatened to be made a party to such an action, suit or proceeding by reason of the fact that he or she is or was or has agreed to become an employee or agent of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as an 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 him or her or on his or her behalf in connection with such action, suit or proceeding and any appeal therefrom, if he or she (x) acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation and, in the case of any such employee or agent, in a manner he or she reasonably believed to be not in violation of any policies or directives of the Corporation, and (y) with respect to any criminal action or proceeding had no reasonable cause to believe his or her conduct was unlawful; except that in the case of an action or suit by or in the right of the Corporation to procure a judgment in its favor (i) such indemnification shall be limited to expenses (including attorneys' fees) actually and reasonably incurred by such person in the defense or settlement

II-3

of such action or suit, and (ii) 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. The indemnification under this Section 6.01 shall apply to all directors and officers of the Corporation who sit on the boards of directors of non-profit corporations in keeping with the Corporation's philosophy."

"The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she 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 reasonable cause to believe that his conduct was unlawful."

As permitted by Section 145 of the General Corporation Law of the State of Delaware and ADP's Certificate and By-Laws, ADP also maintains a directors and officers liability insurance policy which insures, subject to certain exclusions, deductibles and maximum amounts, directors and officers of ADP against damages, judgments, settlements and costs incurred by reason of certain acts committed by such persons in their capacities as directors and officers.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

Not Applicable.

ITEM 8. EXHIBITS

A list of exhibits included as part of this registration statement is set forth in the Exhibit Index which immediately precedes such exhibits and is hereby incorporated by reference herein.

ITEM 9. UNDERTAKINGS

The undersigned Registrant hereby undertakes:

(a) 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 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; (ii) 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; and
(iii) 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, as amended, each filing of the registrant's annual report pursuant to

II-4


5

Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended, 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, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the registrant's Certificate of Incorporation or by-laws, by contract, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act 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 whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

In connection with the registration statement on Form S-8 (the "Registration Statement") filed by Automatic Data Processing, Inc. (the "Company") with the Securities and Exchange Commission on September 6, 2001 pursuant to the Securities Act of 1933, as amended (the "Act"), and the rules and regulations promulgated thereunder (the "Rules"), you have requested that I furnish you with my opinion as to the legality of the 180,525 shares (the "Shares") of the Company's common stock, $0.10 par value per share (the "Common Stock") which are registered under the Registration Statement.

In this regard, I have examined originals, or copies authenticated to my satisfaction, of the Company's Amended and Restated Certificate of Incorporation, the Company's By-Laws, as amended and restated, and the Company's records of corporate proceedings. In addition, I have made such other examinations of law and fact as I considered necessary in order to form a basis for the opinions hereinafter expressed.

Based upon the foregoing, I am of the opinion that the Shares have been duly authorized and, when issued in accordance with the Avert, Inc. Amended and Restated 1994 Stock Incentive Plan, as amended, will be validly issued, fully paid and nonassessable.

I hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement, to its use as part of the Registration Statement, and to the use of my name in the Registration Statement. In giving this consent, I do not admit that I come within the category of persons whose consent is required by the Act or Rules.

Very truly yours,

/s/ James B. Benson
