Item 6.      Indemnification of Directors and Officers.

        Article IX of the Company’s Amended and Restated Bylaws, requires that the Company shall, to the fullest extent permitted or required by Sections 180.0850 to 180.0859, inclusive, of the Wisconsin Business Corporation Law, including any amendments thereto (but in the case of any such amendment, only to the extent such amendment permits or requires the corporation to provide broader indemnification rights than prior to such amendment), indemnify its Directors and Officers against any and all liabilities, and pay or reimburse any and all properly documented reasonable expenses, incurred thereby in any proceedings to which any such Director or Officer is a party because he or she is or was a Director or Officer of the Company. The Company shall also indemnify an employee who is not a Director or Officer, to the extent that the employee has been successful on the merits or otherwise in defense of a proceeding, for all expenses incurred in the proceeding if the employee was a party because he or she is or was an employee of the Company. The rights to indemnification granted under the Bylaws shall not be deemed exclusive of any other rights to indemnification against liabilities or the allowance of expenses which a Director, Officer or employee (or such other person) may be entitled under any written agreement, Board resolution, vote of shareholders of the Company, the Wisconsin Business Corporation Law or otherwise. The Company may, but shall not be required to, supplement the foregoing rights to indemnification against liabilities and allowance of expenses under this paragraph by the purchase of insurance on behalf of any one or more of such Directors, Officers or employees, whether or not the Company would be required or permitted to indemnify or allow expenses to such Director, Officer or employee. All capitalized terms used in this paragraph and not otherwise defined herein shall have the meaning set forth in Section 180.0850 of the Wisconsin Business Corporation Law.

        The Company maintains a liability insurance policy for its Directors and Officers as permitted by Wisconsin law, which may extend to, among other things, liability arising under the Securities Act of 1933, as amended.

        The general effect of the foregoing provisions may be to reduce the circumstances in which an officer or director may be required to bear the economic burden of the foregoing liabilities and expense.

        The Company maintains a liability insurance policy for its directors and officers as permitted by Wisconsin law which may extend to, among other things, liability arising under the Securities Act of 1933.

Item 7.      Exemption from Registration Claimed.

        Not applicable.

Item 8.      Exhibits.

        The exhibits filed herewith or incorporated herein by reference are set forth in the attached Exhibit Index.

        The undersigned registrant hereby undertakes that it has submitted the Plan, and any amendment thereto, to the Internal Revenue Service in a timely manner and has made or will make all changes required by the Internal Revenue Service in order to continue the qualification of the Plan under Section 401 of the Internal Revenue Code of 1986, as amended.

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) of Securities Act 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; 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) 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 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.

            (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 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.

            (4)     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, in a primary offering of securities of the 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 Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

                (i)     Any preliminary prospectus or prospectus of the Registrant relating to the offering required to be filed pursuant to Rule 424 under the Securities Act of 1933;

                (ii)     Any free writing prospectus relating to the offering prepared by or on behalf of the Registrant or used or referred to by the Registrant;

4

                (iii)     The portion of any other free writing prospectus relating to the offering containing material information about the Registrant or its securities provided by or on behalf of the Registrant; and

                (iv)     Any other communication that is an offer in the offering made by the Registrant to the purchaser.

        (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 Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement 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.

        (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 Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

        I am Vice President, General Counsel and Secretary of Regal Beloit Corporation, a Wisconsin corporation (the “Company”), and in that capacity I have acted as counsel to the Company in conjunction with the preparation of a Form S-8 Registration Statement (the “Registration Statement”) to be filed by the Company with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), relating to 175,000 shares of the Company’s common stock, $0.01 par value (the “Common Stock”), and the accompanying rights (“Rights”) to purchase shares of Common Stock, that may be issued pursuant to the Regal Beloit Corporation Retirement Savings Plan (the “Plan”). The terms of the Rights issuable under the Plan are as set forth in that certain Rights Agreement (the “Rights Agreement”), dated as of January 28, 2000, as amended, by and between the Company and EquiServe Trust Company, N.A. (as successor rights agent).

        As counsel to the Company, I have examined: (i) the Registration Statement; (ii) the Plan and related documents; (iii) resolutions of the Board of Directors of the Company relating to the Plan and the issuance of Common Stock and Rights pursuant thereto; (iv) the Company’s Articles of Incorporation, as amended, and Amended and Restated Bylaws; (v) the Rights Agreement; and (vi) such other corporate proceedings, documents and records as I have deemed necessary or appropriate to enable us to render this opinion.

        Based on the foregoing, I am of the opinion that:

        1.     The shares of Common Stock covered by the Registration Statement, when issued by the Company in the manner and for the consideration contemplated by the Plan, will be validly issued, fully paid and nonassessable, subject to the personal liability that may be imposed on shareholders by former Section 180.0622(2)(b) of the Wisconsin Business Corporation Law with respect to wage claims or other debts incurred prior to June 14, 2006 (for debts incurred on or after such date, Section 180.0622(2)(b) has been repealed) owing to employees for services performed, but not exceeding six months service in any one case.

        2.     The Rights to be issued with the Common Stock when issued pursuant to the terms of the Rights Agreement will be validly issued.

Corporate Office • 200 State Street • Beloit, WI 53511-6254 • Fax 608-364-8818 • www.regal-beloit.com

        I consent to the use of this opinion as an Exhibit to the Registration Statement. In giving my consent, I do not admit that I am an “expert” within the meaning of Section 11 of the Securities Act or within the category of persons whose consent is required by Section 7 of said Act.

Very truly yours,

/s/Paul J. Jones
