              Re: Amendment No. 2 to Note and Guarantee Agreement,
                  dated as of April 15, 1998, as amended

To the Holders of the Notes
   Referred to Below

Ladies and Gentlemen:

          Reference is made to the Note and Guarantee Agreement dated as of
     April 15, 1998 (as in effect on the date hereof, the "Agreement") among
     Midas International Corporation, a Delaware corporation (the "Company"),
     Midas, Inc., a Delaware corporation (the "Guarantor" and, together with the
     Company, the "Obligors") and the purchasers whose names appear in the
     acceptance form at the end thereof (each, a "Purchaser" and, collectively,
     the "Purchasers"), pursuant to which the Purchasers purchased $75,000,000
     aggregate principal amount of the Company's 6.89% Guaranteed Senior Notes
     due 2005 (the "Notes").

          The Company has requested that the holders of the Notes, and the
     holders of the Notes party hereto are willing to, amend Section 10.6 of the
     Agreement as provided herein, all on the terms and conditions of this
     Amendment.

          Accordingly, in consideration of the premises and the mutual
     agreements contained herein, and for other good and valuable consideration,
     the receipt and sufficiency of which are hereby acknowledged, the parties
     hereto agree as follows:

     Section 1. Definitions. Unless otherwise defined herein, all terms used
herein that are defined in the Agreement (as amended hereby) shall have their
respective meanings as therein defined.

     Section 2. Amendments to Agreement. Subject to the satisfaction of the
conditions to effectiveness specified in Section 4 below, but with effect on and
after the date hereof

          2.1 Section 10.6. Section 10.6 of the Agreement shall be amended and
     restated to read in its entirely as follows:

          "Section 10.6 Consolidated Indebtedness Ratio. The Guarantor will not
     permit the ratio of Consolidated Indebtedness to EBITDA to exceed (i) 4.25
     to 1.00 as at the end of the fiscal quarter

<PAGE>

     of the Guarantor ending December 28, 2002 and (ii) 3.5 to 1:00 as at the
     end of any other fiscal quarter of the Guarantor."

          2.2 Further Restrictions on Liens. Notwithstanding anything in the
     Agreement to the contrary, after December 27, 2002, the Guarantor will not,
     and will not permit any Subsidiary to, create, assume, incur, guarantee or
     otherwise become liable in respect of any Priority Indebtedness other than
     the Excess Advances, and the Guarantor will not, and will not permit any
     Subsidiary to, grant, create, assume or incur any Lien to secure Priority
     Indebtedness upon or with respect to any property or assets, whether now
     owned or hereafter acquired, of the Guarantor or any such Subsidiary other
     than Liens granted and required to be granted pursuant to section 1(j) of
     the Sixth Bank Amendment; provided that the Guarantor and any Subsidiary
     shall be allowed to incur unsecured trade debt in the ordinary course of
     business. The undersigned Purchasers hereby acknowledge that the granting
     of Liens in connection with the Sixth Bank Amendment and the incurring of
     the Excess Advances did not and will not constitute a violation of the
     terms of the Agreement. Any default under this Section 2.2 will constitute
     an Event of Default under the Agreement. For purposes of the preceding
     sentence,

          "Excess Advances" shall have the meaning specified in section 1(j) of
     the Sixth Bank Amendment;

          "Priority Indebtedness" shall have the same meaning as the meaning of
     Priority Debt set forth in the Agreement, but without giving effect to the
     exclusion in clause (ii) of the definition of "Priority Debt"; and

          "Sixth Bank Amendment" shall mean the Amendment No. 6 and Waiver to
     Credit Agreement dated as of November 12, 2002 by and among the Obligors,
     Bank One, NA, as administrative agent, Credit Suisse First Boston, as
     co-agent, and the lenders signatory thereto.

     Section 3. Representations and Warranties of the Obligors. The Company and
the Guarantor jointly and severally represent and warrant to the holders of the
Notes as follows (and the parties hereto agree that the following
representations and warranties shall be deemed to have been made pursuant to the
Agreement for all relevant purposes thereof):

          3.1. Power and Authority. Each Obligor has the corporate power and
     authority to execute and deliver this Amendment and to perform the
     Agreement as amended hereby (the "Amended Agreement").

          3.2. Authorization. etc. This Amendment has been duly authorized by
     all necessary corporate action on the part of each Obligor, and has been
     duly executed and delivered by each Obligor, and the Amended Agreement
     constitutes a legal, valid and binding obligation of each Obligor,
     enforceable against such Obligor, in accordance with its terms, except as
     such enforcement may be limited by (i) applicable bankruptcy, insolvency,
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally and (ii) general principles of equity
     (regardless of whether such enforceability is considered in a proceeding in
     equity or at law).

                                       2

<PAGE>

          3.3. No Conflicts. The execution, delivery and performance by the
     Obligors of this Amendment and of the Amended Agreement will not (i)
     contravene, result in any breach of, or constitute a default under, or
     result in the creation of any Lien in respect of any property of either
     Obligor or any Subsidiary under, any indenture, mortgage, deed of trust,
     loan, purchase or credit agreement, lease, corporate charter or by-laws, or
     any other agreement or instrument to which either Obligor or any Subsidiary
     is bound or by which either Obligor or any Subsidiary or any of their
     respective properties may be bound or affected, (ii) conflict with or
     result in a breach of any of the terms, conditions or provisions of any
     order, judgment, decree, or ruling of any court, arbitrator or Governmental
     Authority applicable to either Obligor or any Subsidiary or (iii) violate
     any provision of any statute or other rule or regulation of any
     Governmental Authority applicable to either Obligor or any Subsidiary.

          3.4. No Defaults. Both immediately prior and after-giving effect to
     this Amendment, no Default or Event of Default has occurred and is
     continuing.

          5.2. Ratification/Waiver. The Agreement, except as amended pursuant

     and agreements thereof shall remain in full force and effect.

          5.3. References to Agreement and Notes. From and after the date

     accordance with, and the rights of the parties shall be governed by, the
     law of the State of New York excluding choice-of-law principles of the law

                     dated as of April 15, 1998, as amended

To the Holders of the Notes
   Referred to Below

Ladies and Gentlemen:

     Reference is made to the Note and Guarantee Agreement dated as of April 15,
1998 (as in effect on the date hereof, the "Agreement") among Midas
International Corporation, a Delaware corporation (the "Company"), Midas, Inc.,
a Delaware corporation (the "Guarantor" and, together with the Company, the

to which the Purchasers purchased $75,000,000 aggregate principal amount of the
Company's 6.89% Guaranteed Senior Notes due 2005 (the "Notes").

     The Company has requested that the holders of the Notes, and the holders of
the Notes party hereto are willing to, amend Section 10.7 of the Agreement and

     Accordingly, in consideration of the premises and the mutual agreements
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as

     Section 1. Definitions. Unless otherwise defined herein, all terms used
herein that are defined in the Agreement (as amended hereby) shall have their
respective meanings as therein defined.

     Section 2. Amendments to Agreement. Subject to the satisfaction of the

          amortization expenses and other non-cash charges, (iii) cash charges
          not in excess of $31,000,000 relating to Midas's previously disclosed

          Consolidated Net Worth to be less than the sum of (a) $71,700,000 plus
          (b) an amount equal to 50% of Consolidated Net Income for each
          completed fiscal quarter of the Guarantor ending on or after March 28,
          1998 (but only if Consolidated Net Income for such fiscal quarter is a

          extent it is reflected in the determination of Consolidated Net Worth
          as of the date of the Closing), less (c) cash charges not in excess of
          $31,000,000 relating to Midas's previously disclosed restructuring
