In a derivative action, i.e, one by or in the right of a corporation, the corporation is permitted to indemnify any of its directors or officers against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable to the corporation, unless and only to the extent that the court in which such action or suit was brought shall determine upon application that such person is fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability. Article Eleventh of the Corporation's Restated Certificate of Incorporation provides for indemnification of directors and officers of the Corporation against liability they may incur in their capacities as such to the fullest extent permitted by the DGCL. The Corporation has entered into indemnification agreements with its directors and officers. Pursuant to such agreements, the Corporation will, to the extent permitted by applicable law, indemnify such persons against all expenses incurred in connection with the defense or settlement of any proceeding brought against them by reason of the fact that they were directors or officers of the Corporation. The DGCL also provides that Delaware corporations may purchase insurance on behalf of any such director, officer, employee or agent. The Corporation has purchased and maintains insurance on behalf of the Corporation's directors and officers. Item 7.

Undertakings. ------------- (a) The undersigned registrant 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 the 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) (S 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than 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 the Registration Statement or any material change to such information in the Registration Statement; Provided however, that: (A) Paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the registration statement is on Form S-8 (S 239.16b of this chapter), and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities and Exchange Act of 1934 (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the registration statement; and (B) Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 (S 239.13 of this chapter) or Form F-3 (S 239.33 of this chapter) and the information required to be included in a post-effective amendment by those paragraphs is contained in 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 the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) (S 230.424(b) of this chapter) that is part of the registration statement; and (C) Paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is for an offering for asset-backed securities on Form S-1 (S 239.11 of this chapter) or Form S-3 (S 239.13 of this chapter), and the information required to be included in a post-effective amendment is provided pursuant to Item 1100(c) of Regulation AB (S 229.1100(c)). (2) That, for the purpose of determining any liability under the Securities Act, 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. (5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser: (i) If the registrant is relying on Rule 430B (S 230.430B of this chapter): (A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) (S 230.424(b)(3) of this chapter) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and (B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) (S 230.424(b)(2), (b)(5), or (b)(7) of this chapter) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) (S 230.415(a)(1)(i), (vii), or (x) of this chapter) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchase with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or (ii) If the registrant is subject to Rule 430C (S 230.430C of this chapter), each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A (S 230.430A of this chapter), shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use. (6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will e considered to offer or sell such securities to such purchaser: (i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 (S 230.424 of this chapter); (ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act 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 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, 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 Securities 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 Securities Act and will be governed by the final adjudication of such issue. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all the requirements for filing on Form S-8 and has caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Monett, State of Missouri, on this 2nd day of December, 2005.

 Monett, Missouri  65708-0807

 Ladies and Gentlemen:

 I have acted as General Counsel to Jack Henry & Associates, Inc., a Delaware
 corporation  (the  "Corporation"),  in  connection  with  the  filing  of  a
 registration statement on Form S-8 (the "Registration Statement"),  with the
 Securities and Exchange  Commission (the "Commission")  for the purposes  of
 registering under the Securities  Act of 1933,  as amended (the  "Securities
 Act"), 3,000,000 shares of the  Corporation's common stock, par  value $0.01
 per share  (the  "Common  Stock") issuable  pursuant  to  the Jack  Henry  &
 Associates, Inc. Restricted Stock Plan (the "Plan").  Such shares  of Common
 Stock issuable pursuant to the Plan are herein referred to as "the Shares."

 In connection therewith, I  have examined originals  or copies certified  or
 otherwise identified to  my satisfaction, of  those documents, corporate  or
 other  records,  certificates  and  other  papers  that  I  deemed necessary
 to examine  for purposes  of this  opinion.  I  have  also  relied,  without
 investigation as the  accuracy thereof, on  oral and written  communications
 from officers of the Corporation.

 Based upon the foregoing and subject to the qualifications set forth in this
 letter, I am of the opinion that the Shares have been validly authorized and
 will be, when issued and delivered pursuant to the Plan, fully paid and non-
 assessable.

 I hereby  consent  to the  filing  of this  opinion  as  an Exhibit  to  the
 Registration Statement, and further consent to  the use of my  name wherever
 appearing in the Registration Statement.

 Very truly yours,

 /s/ Robert T. Schendel, Esq.
