Pursuant to the authority granted pursuant to Section 24 of the Employee Stock Purchase Plan (the "Plan") of The Hackett Group, Inc. (the "Company"), the Board of Directors of the Company hereby amends the following sections of the Plan:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Section 1 of the Plan is hereby amended and restated in its entirety as follows:

**1. SHARES SUBJECT TO THE PLAN.** 

Subject to adjustment as provided in Section 26 below, the aggregate number of shares of Common Stock that may be made available for purchase by participating employees under the Plan is 5,025,000. The shares of Common Stock issuable under the Plan may, in the discretion of the Board of Directors of the Company (the "Board"), be either authorized but unissued shares of treasury shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;II. Section 25 of the Plan is hereby amended and restated in its entirety as follows:

**25. EFFECTIVE DATE; TERM AND TERMINATION OF THE PLAN.** 

The Plan, as amended by Amendment No. 5, shall be effective as of the date of adoption of the amendment by the Board, which date is set forth below, subject, in the case of the amendment to Section 1, to approval of the Plan, as amended by Amendment No. 5, by a majority of the votes present and entitled to vote at a duly held meeting of the shareholders of the Company at which a quorum representing a majority of all outstanding voting stock is present, either in person or by proxy provided, however, that upon approval of the Plan, as amended by Amendment No. 5, by the shareholders of the Company as set forth above, all rights to purchase shares granted under the Plan, as amended by Amendment No. 5, on or after the effective date shall be fully effective as if the shareholders of the Company had approved the plan on the effective date. If the shareholders fail to approve the Plan, as amended by Amendment No. 5, on or before one year after the effective date, the terms of Section 1 of Amendment No. 5 shall not take effect, but all other provisions of the Plan, as amended by Amendment No. 5, including the termination date, shall be in effect. The Board may terminate the Plan at any time and for any reason or for no reason, provided that such termination shall not impair any rights of participating employees that have vested at the time of termination. In any event, the Plan shall, without further action of the Board, terminate on July 1, 2031 or, if earlier, at such time as all shares of Common Stock that may be made available for purchase under the Plan, as amended pursuant to Section 1 above, have been issued.

Re: The Hackett Group, Inc. Employee Stock Purchase Plan Registration Statement on Form S-8

Gentlemen and Ladies:

I am General Counsel of The Hackett Group, Inc., a Florida corporation (the "Company"). This opinion letter has been prepared in connection with the Company's registration, pursuant to a registration statement on Form S-8 filed with the Securities and Exchange Commission on or about the date hereof (the "Registration Statement"), of 250,000 shares (the "Shares") of common stock, $.001 par value per share, of the Company which may be issued pursuant to the Company's Employee Stock Purchase Plan, as amended (the "Plan"). This letter is furnished pursuant to the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. (S) 229.601(b)(5), in connection with such registration.

For purposes of this opinion letter, I have examined copies of such agreements, instruments and documents as I have deemed an appropriate basis on which to render the opinion hereinafter expressed. In my examination of the aforesaid documents, I have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to me, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to me as copies (including pdfs). As to all matters of fact, I have relied on the representations and statements of fact made in the documents so reviewed, and I have not independently established the facts so relied on.

This opinion letter is based as to matters of law solely on the Florida Business Corporation Act, as amended. I express no opinion herein as to any other statutes, rules or regulations.

Based upon, subject to and limited by the foregoing, I am of the opinion that the Shares, when issued and delivered in the manner and on the terms contemplated in the Registration Statement and the Plan (with the Company having received the consideration therefor, the form of which is in accordance with the applicable resolutions of the Board of Directors or a duly authorized committee thereof and in the Plan), will be validly issued, fully paid and non-assessable.

I hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the reference to my name under the caption "Interests of Named Experts and Counsel" in the Registration Statement. In giving my consent, I do not admit that I am in the category of persons whose consent is required under Section 7 of the Securities Act of 1933 nor the rules of the Securities and Exchange Commission thereunder.
