Item 4. Description of Securities. ------------------------- Not applicable. Item 5. Interests of Named Experts and Counsel. -------------------------------------- An opinion stating that the securities registered hereunder, when issued in accordance with the provisions of the Plan, will be valid and binding obligations of the Company has been rendered to the Company on September 30, 1999 by Ellen J. Curnes, Senior Corporate Counsel of the Company. Ms. Curnes is the beneficial owner of options to purchase 1,000 shares of the Company's Common Stock. Item 6. Indemnification of Directors and Officers. ----------------------------------------- The Company is a Utah corporation. Section 16-10a-901 et seq. of the Revised Business Corporation Act of Utah grants to a corporation the power and in certain cases requires corporations to indemnify a person made a party to a lawsuit or other proceeding because such person is or was a director or officer. A corporation is further empowered to purchase insurance on behalf of any person who is or was a director or officer against any liability asserted against him or her and incurred by him or her in such capacity or arising out of his or her status as such capacity. The Company's By-Laws provide for mandatory indemnification of its directors, officers and employees in certain circumstances. The Company maintains insurance on behalf of directors and officers against liability asserted against them arising out of their status as such. The Company's Articles of Incorporation eliminate in certain circumstances the personal liability of directors of the Company for monetary damages for a breach of their fiduciary duty as directors. This provision does not eliminate the liability of a director for (i) the amount of a financial benefit received by a director to which he or she is not entitled, (ii) an intentional infliction of harm on the corporation or the shareholders, (iii) a violation of Section 16- 10a-842 of the Revised Business Corporation Act of Utah (relating to the liability of directors for unlawful distributions) or (iv) an intentional violation of criminal law. -2-

Item 7. Exemption from Registration Claimed. ----------------------------------- Not applicable. Item 8. Exhibits. --------- The exhibits filed as part of this Registration Statement are as follows: Exhibit Number Exhibit - -------------- ------- 5 - Opinion of Ellen J. Curnes 23.1 - Consent of Deloitte & Touche LLP 23.2 - Consent of Ellen J. Curnes (included in Exhibit 5 above) 24 - Powers of Attorney Item 9. Undertakings. ------------ (a) The undersigned 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; (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; (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 (a)(1)(i) and (a)(1)(ii) of this Section 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 Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement. -3-

(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. (b) The undersigned Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company's Annual Report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) 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. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the 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 payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company 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 Company 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. -4-
