1) All securities offered pursuant to this Registration Statement are outstanding shares, and no authorized but unissued stock will be utilized. Since the 1993 StockBuilder Plan continues with no maximum number of shares and no termination date, the number of shares being registered is an estimate of the number of shares to be purchased under the Plan through November 19, 2002. This Registration Statement shall also cover any additional shares of Common Stock which become issuable under the 1993 StockBuilder Plan, by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the receipt of consideration which results in an increase in the number of the Registrant’s outstanding shares of Common Stock.

2) Estimated solely for the purpose of computing the registration fee. Pursuant to Rule 457(h), the calculation of the registration fee is based on the average of the high and low sales prices of the Registrant’s Common Stock on November 12, 2001, as reported by The Nasdaq Stock Market, Inc.

Item 4. Description of Securities.

           Not applicable.

Item 5. Interest of Named Experts and Counsel.

           Not applicable.

Item 6. Indemnification of Directors and Officers.

     Section 102 of the Delaware General Corporation Law permits a Delaware corporation to include in its certificate of incorporation a provision eliminating or limiting a director’s personal liability to the corporation or its stockholders for monetary damages for breaches of fiduciary duty, including conduct which could be characterized as negligence or gross negligence. The Delaware General Corporation Law expressly provides, however, that the liability for breaches of the duty of loyalty, acts or omissions

-3-

not in good faith or involving intentional misconduct or knowing violation of the law, the unlawful purchase or redemption of stock or payment of unlawful dividends or the receipt of improper personal benefits cannot be eliminated or limited in this manner. The Delaware General Corporation Law further provides that no such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective. Article Ninth of the Registrant’s Second Restated Certificate of Incorporation provides that a director shall not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by the Delaware General Corporation Law.

     Section 145 of the Delaware General Corporation Law makes provision for the indemnification of directors, officers, employees and agents against expenses, judgments, fines, settlements and other amounts incurred in connection with any proceeding arising by reason of the fact that such person is or was a director, officer, employee or agent of the corporation. Article VIII of the Registrant’s By-laws provides that the Registrant shall indemnify its directors, officers, employees and agents to the fullest extent permitted by applicable law.

     The Registrant carries insurance that purports to insure its officers and directors against certain liabilities incurred by them in the discharge of their official functions.

     The Registrant has entered into indemnification agreements with each of its directors. The indemnification agreements require, among other things, that the Registrant indemnify such directors to the fullest extent permitted by law and advance to the directors all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted.

Item 7. Exemption from Registration Claimed.

         Not applicable.

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 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) if, in the aggregate, the changes in volume and price represent no more than 20 percent 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 paragraphs a(1)(i) and a(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and 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 Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

     (2)  That, for the purpose of determining any liability under the Securities Act of 1933, 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.

-5-

     (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 of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or 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.

     (c)  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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.
