            Amendment to 1998 Incentive Plan Dated December 15, 2000


     The Lennox  International  Inc. 1998 Incentive Plan, as amended,  is hereby
amended to delete Paragraph 5 of the Plan, in its entirety,  and replace it with
the following:

     "5.  Common  Stock  Available  for  Awards.  Subject to the  provisions  of
paragraph 15 hereof, there shall be available for Awards under this Plan granted
wholly or  partly  in Common  Stock  (including  rights or  options  that may be
exercised  for or settled in Common  Stock) an aggregate of 7,541,635  shares of
Common  Stock,  of which an aggregate  of not more than 660,000  shares shall be
available for Director  Awards and the remainder shall be available for Employee
Awards and Independent  Contractor  Awards. The number of shares of Common Stock
that  are the  subject  of  Awards  under  this  Plan,  that  are  forfeited  or
terminated,  expire unexercised,  are settled in cash in lieu of Common Stock or
in a manner  such  that all or some of the  shares  covered  by an Award are not
issued to a Participant  or are exchanged for Awards that do not involve  Common
Stock,  shall again  immediately  become  available  for Awards  hereunder.  The
Committee may from time to time adopt and observe such procedures concerning the
counting of shares  against  the Plan  maximum as it may deem  appropriate.  The
Board and the  appropriate  officers of the Company shall from time to time take
whatever actions are necessary to file any required  documents with governmental
authorities,  stock exchanges and transaction  reporting  systems to ensure that
shares of Common Stock are available for issuance pursuant to Awards."

Ladies and Gentlemen:

     As set forth in the Registration  Statement on Form S-8 (the  "Registration
Statement")  to be filed by Lennox  International  Inc., a Delaware  corporation
(the  "Company"),   with  the  Securities  and  Exchange  Commission  under  the
Securities  Act of 1933,  as amended  (the  "Securities  Act"),  relating to the
offering  of up to  2,938,135  additional  shares (the  "Shares")  of the common
stock, par value $0.01 per share ("Common Stock"),  of the Company,  pursuant to
the 1998 Incentive Plan of Lennox International Inc. (the "Plan"), certain legal
matters in  connection  with the Shares are being passed upon for the Company by
me. At the Company's request, this opinion is being furnished to the Company for
filing as Exhibit 5 to the Registration Statement.

     In my  capacity  as counsel to the  Company  in the  connection  referenced
above, I have examined the Company's  Restated  Certificate of Incorporation and
Amended and Restated  Bylaws,  each as amended to date,  and the Plan,  and have
examined  the  originals,  or  copies  certified  or  otherwise  identified,  of
corporate  records  of the  Company,  including  minute  books  of the  Company,
certificates of public officials and of representatives of the Company, statutes
and other  instruments  and  documents as a basis for the  opinions  hereinafter
expressed.

     I have  assumed that all  signatures  on all  documents  examined by me are
genuine, that all documents submitted to me as originals are authentic, that all
documents submitted to me as copies are true and correct copies of the originals
thereof and that all information submitted to me was accurate and complete.

     Based upon my  examination  as aforesaid,  and subject to the  assumptions,
qualifications, limitations and exceptions herein set forth, I am of the opinion
that:

     1. The Company is a corporation  duly  incorporated and validly existing in
good standing under the laws of the State of Delaware.

                                       1

2. When issued and sold from time to time in accordance with the provisions of the Plan (and any applicable agreements pertaining to awards granted or to be granted under the Plan) pursuant to awards granted by, and for consideration fixed by, the Committee of the Board of Directors of the Company charged with administering the Plan, the Shares will be duly authorized by all necessary corporate action on the part of the Company, validly issued, fully paid and nonassessable. The opinions set forth above are limited to the General Corporation Law of the State of Delaware, and no opinion is expressed herein as to matters governed by the law of any other jurisdiction. I hereby consent to the filing of this opinion as an exhibit to the Registration Statement. Very truly yours, /s/ Carl E. Edwards, Jr. ------------------------------ Carl E. Edwards, Jr. 2
