Item 5. Interests of Named Experts and Counsel

Item 6. Indemnification of Directors and Officers

(a) Section 145 of the Delaware General Corporation Law (the "DGCL") (i) gives Delaware corporations broad powers to indemnify their present and former directors and officers and those of other enterprises, as well as certain other persons, against expenses, judgments, fines and settlement amounts incurred by such directors, officers or other persons in defense of any action, suit or proceeding to which they are made parties by reason of being or having been a director, officer, employee or agent of the corporation, or of another enterprise at the request of the corporation, subject to specified conditions and exclusions, (ii) gives such directors, officers or other persons who are successful in the defense of any action, suit or proceeding the right to be indemnified, and (iii) authorizes the corporation to purchase and maintain directors' and officers' liability insurance. The indemnification authorized by Section 145 of the DGCL is not exclusive of any other rights to which those indemnified may be entitled under any bylaws, agreement, vote of shareholders or disinterested directors, policy of insurance or otherwise.

(b) Article Tenth of the Registrant's Restated certificate of incorporation authorizes the Registrant to agree to indemnify any of its directors, officers, employees or agents, and any person who serves at the request of the Registrant as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, to the fullest extent permitted by the laws of the state of Delaware; provided that the Registrant is not permitted to indemnify any person from or on account of such person's conduct which was finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct.

(c) In accordance with Section 102(b)(7) of the DGCL, Article Tenth of the Registrant's Restated certificate of incorporation contains a provision eliminating a director's personal liability to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted or authorized by the laws of the state of Delaware.
Section 102(b)(7) of the DGCL prohibits the elimination or limitation of a director's liability (1) for any breach of the director's duty of loyalty to the Registrant or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or knowing violations of law, (3) under Section 174 of the DGCL (relating to unlawful dividend payments or stock redemptions or repurchases), or (4) for any transaction from which the director derived an improper personal benefit.

(d) Section 28 of the Registrant's bylaws requires the Registrant to indemnify any person (1) against all liabilities and expenses actually and reasonably incurred by such person in connection with any action, suit or proceeding (other than an action by or in the right of the Registrant) or (2) against any amounts paid in settlement and expenses actually and reasonably incurred by such person in an action by or in the right of the Registrant, in either case, by reason of the fact that such person is or was serving as a director or officer of the Registrant or as a director or officer of another enterprise at the Registrant's request; provided that (a) such person must have acted in good faith and in a manner such person reasonably believed to be in or not opposed to the Registrant's best interests and, with respect to any criminal action or proceeding, that such person must have had no reasonable cause to believe such person's conduct was unlawful, and (b) the Registrant is not required to indemnify or advance expenses to such person in connection with an action, suit or proceeding initiated by such person unless the initiation of such action, suit or proceeding was authorized by the Registrant's Board of Directors. Said Section 28 further provides that the Registrant shall not indemnify any person for any liabilities or expenses incurred by such person in connection with an action, suit or proceeding by or in the right of the Registrant in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Registrant, unless and only to the extent that the court in which the action, suit or proceeding is brought determines that the person is entitled to such indemnity. If any person serving as a director or officer of the Registrant or as a director or officer of another enterprise at the Registrant's request is successful on the merits or otherwise in defense of any action, suit or proceeding referred to above, said Section 28 requires that the Registrant indemnify such person against expenses actually and reasonably incurred by such person in connection therewith. Prior to indemnifying a person pursuant to Section 28 of the Registrant's bylaws, the Registrant must determine that such person has met the specified standard of conduct required for indemnification unless ordered by a court and except as otherwise provided by the immediately preceding sentence. Such determination must be made by
(y) a majority vote of a quorum of the directors who were not party to the action, suit or proceeding (or by independent legal counsel in a written opinion if so directed by a quorum of disinterested directors or if such a quorum is not obtainable), or (z) the stockholders. If the determination is adverse to the person seeking to be indemnified, such person may cause the determination to be made by a court having jurisdiction over the Registrant. The indemnification provided by Section 28 of the Registrant's bylaws is not exclusive of any other rights


to which those seeking indemnification may be entitled under any statute, the Registrant's Restated certificate of incorporation, the Registrant's bylaws, any agreement, vote of stockholders or disinterested directors, policy of insurance or otherwise, both as to action in their official capacities and as to action in other capacities while holding their respective offices.

(e) The Registrant has entered into indemnification agreements with the Registrant's directors, Clifford W. Illig, Neal L. Patterson, Michael E. Herman, Jeff Goldsmith, Gerald E. Bisbee, Jr., and John C. Danforth, which, among other things, (a) confirm the present indemnity permitted under the DGCL, (b) provide that, in addition, the directors shall be indemnified to the fullest possible extent permitted by law against all expenses (including attorneys' fees), judgments, fines, and settlement amounts, paid or incurred by them in any action or proceeding, including any action by or in the right of the Registrant, on account of their services as a director of the Registrant or as a director of any subsidiary of the Registrant or as a director, officer, employee or agent of any other company or enterprise when they are serving in such capacities at the request of the Registrant, and (c) provide procedures for notification and defense of a claim. However, no indemnity will be provided to any director on account of conduct which is adjudged to be knowingly fraudulent, deliberately dishonest or willful misconduct. The indemnification agreements also provide that the Registrant will advance the expenses of defending an action, lawsuit or other proceeding to the indemnified director before the matter is disposed of if the indemnitee agrees to repay any such advances to the Registrant if it is later determined that he or she was not entitled to indemnification.

(f) Section 28 of the Registrant's bylaws permits the Registrant to insure any person against any liability incurred by such person by reason of the fact that such person is or was serving as a director or officer of the Registrant or as a director or officer of another enterprise at the Registrant's request, whether or not the Registrant would have the power to indemnify such person under the provisions described above. The Registrant has obtained directors' and officers' liability insurance for each of its directors and executive officers which (subject to certain limits and deductibles) (i) insures such persons against loss arising from certain claims made against them by reason of such persons being a director or officer, and (ii) insures the Registrant against loss which it may be required or permitted to pay as indemnification due such persons for certain claims. Such insurance may provide coverage for certain matters as to which the Registrant may not be permitted by law to provide indemnification.

Item 9. Undertakings

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;

(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 hereto) which, individually or in the aggregate, represent a fundamental change in the information set forth in the 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 paragraphs (1)(i) and
(1)(ii) do not apply if the information required to be included in a posteffective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

(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 herein, 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.

(2) 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 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 the 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.

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 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 Act and is therefore unenforceable.

Cerner Corporation

Ladies and Gentlemen:

Reference is made to the Post-Effective Amendment No. 1 on Form S-8 to the registration statement on Form S-4 which Cerner Corporation (the "Company") proposes to file with the Securities and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended, registering 78,818 common shares, par value $.01 per share (including an equal number of preferred share purchase rights that initially trade with the common shares), of the Company (the "Shares") which may be offered and sold by the Company under the CITATION Computer Systems, Inc. Stock Plans set forth on the cover page of the Post- Effective Amendment No. 1 (the "Plans"). I am of the opinion that all proper corporate proceedings have been taken so that any Shares to be offered and sold which are of original issuance, upon sale and payment in accordance with the Plans and the resolutions of the Board of Directors relating to the offering and sale of Shares, will be legally issued, fully paid and nonassessable. I hereby consent to the filing of this opinion with the SEC in connection with the Post Effective Amendment No. 1.

Very truly yours,

/s/ Randy D. Sims
