Item 5. Interests of Named Experts and Counsel. -------------------------------------- Not Applicable. Item 6. Indemnification of Directors and Officers. ----------------------------------------- In accordance with Section 145 of the General Corporation Law of the State of Delaware, Article VII of the Registrant's Restated Certificate of Incorporation (the "Certificate") provides that no director of the Registrant shall be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) in respect of certain unlawful dividend payments or stock redemptions or repurchases, or (iv) for any transaction from which the director derived an improper personal benefit. In addition, the Certificate provides that if the Delaware General Corporation Law is amended to authorize the further elimination or limitation of the personal liability of directors, then the liability of a director of the Registrant shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended. Article V of the Registrant's Amended and Restated By-laws (the "By-laws") provides for indemnification by the Registrant of its directors, officers and certain non-officer employees (including officers and certain non-officer employees of subsidiaries) under certain circumstances against expenses (including attorneys fees, judgments, fines and amounts paid in settlement) reasonably incurred in connection with the defense or settlement of any threatened, pending or completed legal proceeding in which any such person is involved by reason of the fact that such person is or was a director, an officer or an employee of the Registrant if such person 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 Registrant, and with respect to criminal actions or proceedings, that such person had no reasonable cause to believe his or her conduct was unlawful. The Registrant has entered into indemnification agreements with each of its directors reflecting the foregoing provisions of its By-laws and requiring the advancement of expenses in proceedings, if such person had no reasonable cause to believe his or her conduct was unlawful. The Investment and Stockholders' Agreement dated as of February 7, 1994 by and among SAS Acquisition Corp., SAS Software, Inc., Dr. John A. Swanson, the TA Investors (as defined therein) and Marcia S. Morton, as amended, provides for indemnification by the Registrant of certain of its stockholders and the controlling persons of such stockholders against claims and liabilities, including claims and liabilities arising under the securities laws, subject to certain limitations. Under Section 8 of the Underwriting Agreement filed as Exhibit 1.1 to the Prospectus, the Underwriters have agreed to indemnify, under certain conditions, the Registrant, its directors, certain officers and persons who control the Registrant within the meaning of the Securities Act of 1993 against certain liabilities. Item 7. Exemption from Registration Claimed. ----------------------------------- Not Applicable. Item 8. Exhibits. -------- The following is a complete list of exhibits filed or incorporated by reference as part of this Registration Statement. 3

Exhibits - -------- 5.1 Opinion of Goodwin, Procter & Hoar LLP as to the legality of the securities being registered 23.1 Consent of Goodwin, Procter & Hoar LLP (included in Exhibit 5.1) 23.2 Consent of Coopers & Lybrand L.L.P. 24.1 Powers of Attorney (included on signature pages to this Registration Statement) Item 9. 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; (ii) To reflect in the prospectus any acts 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 offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and (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) herein do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the undersigned 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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (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 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 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 4

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. 5
