Dear Ladies and Gentlemen:

         Lennox International Inc., a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the several Underwriters (as defined below)
hereto, and certain stockholders of the Company (the "SELLING STOCKHOLDERS")
named in Schedule I hereto severally propose to sell to the several
Underwriters, an aggregate of 8,500,000 shares of the Common Stock, par value
$.01 per share, of the Company (the "FIRM SHARES"), of which 8,088,490 shares
are to be issued and sold by the Company and 411,510 shares are to be sold by
the Selling Stockholders, each Selling Stockholder selling the amount set forth
opposite such Selling Stockholder's name in Schedule I hereto.

         It is understood that, subject to the conditions hereinafter stated,
6,800,000 Firm Shares (the "U.S. FIRM SHARES") will be sold to the several U.S.
Underwriters named in Schedule II hereto (the "U.S. UNDERWRITERS") in connection
with the offering and sale of such U.S. Firm Shares in the United States (as
defined below) and Canada to United States or Canadian Persons (as defined
below), and 1,700,000 Firm Shares (the "INTERNATIONAL SHARES") will be sold to
the several International Underwriters named in Schedule III hereto (the
"INTERNATIONAL UNDERWRITERS") in connection with the offering and sale of such
International Shares outside the


   3




United States and Canada to persons other than United States or Canadian
Persons. Morgan Stanley & Co. Incorporated, Credit Suisse First Boston
Corporation and Warburg Dillon Read LLC, a subsidiary of UBS AG, shall act as
representatives (the "U.S. REPRESENTATIVES") of the several U.S. Underwriters,
and Morgan Stanley & Co. International Limited, Credit Suisse First Boston
(Europe) Limited and UBS AG, acting through its division Warburg Dillon Read,
shall act as representatives (the "INTERNATIONAL REPRESENTATIVES") of the
several International Underwriters. The U.S. Underwriters and the International
Underwriters are hereinafter collectively referred to as the "UNDERWRITERS".

         "UNITED STATES OR CANADIAN PERSON" shall mean any national or resident
of the United States or Canada, or any corporation, pension, profit-sharing or
other trust or other entity organized under the laws of the United States or
Canada or of any political subdivision thereof (other than a branch located
outside the United States and Canada of any United States or Canadian Person),
and shall include any United States or Canadian branch of a person who is
otherwise not a United States or Canadian Person. "UNITED STATES" shall mean the
United States of America, its territories, its possessions and all areas subject
to its jurisdiction.

         The Company also proposes to issue and sell to the several U.S.
Underwriters not more than an additional 1,275,000 shares of its Common Stock,
par value $.01 per share (the "ADDITIONAL SHARES") if and to the extent that the
U.S. Representatives shall have determined to exercise, on behalf of the U.S.
Underwriters, the right to purchase such shares of common stock granted to the
U.S. Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares
are hereinafter collectively referred to as the "SHARES". The shares of Common
Stock, par value $.01 per share, of the Company to be outstanding after giving
effect to the sales contemplated hereby are hereinafter referred to as the
"COMMON STOCK". The Company and the Selling Stockholders are hereinafter
sometimes collectively referred to as the "SELLERS".

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement relating to the Shares. The registration
statement contains two prospectuses to be used in connection with the offering
and sale of the Shares: the U.S. prospectus, to be used in connection with the
offering and sale of Shares in the United States and Canada to United States or
Canadian Persons, and the international prospectus, to be used in connection
with the offering and sale of Shares outside the United States and Canada to
persons other than United States or Canadian Persons. The international
prospectus is identical to the U.S. prospectus except for the outside front
cover page. The registration statement as amended at the time it becomes
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), is hereinafter
referred to as the "REGISTRATION STATEMENT"; the U.S. prospectus and the
international prospectus in the respective forms first used to confirm sales of
Shares are hereinafter referred to as the "PROSPECTUS". If the Company has filed
an abbreviated registration statement to register additional shares of Common
Stock pursuant to Rule 462(b) under the Securities Act (the "RULE 462
REGISTRATION STATEMENT"), then


                                       -2-

   4




any reference herein to the term "REGISTRATION STATEMENT" shall be deemed to
include such Rule 462 Registration Statement.

         As part of the offering contemplated by this Agreement, Morgan Stanley
& Co. Incorporated ("MORGAN STANLEY") and certain other Underwriters have agreed
to reserve out of the Shares set forth opposite their names on Schedule II to
this Agreement up to 425,000 shares for sale to the Company's employees,
officers and directors and other parties associated with the Company
(collectively, "PARTICIPANTS"), as set forth in the Prospectus under the heading
"Underwriting" (the "DIRECTED SHARE PROGRAM"). The Shares to be sold by such
Underwriters pursuant to the Directed Share Program (the "DIRECTED SHARES") will
be sold by such Underwriters pursuant to this Agreement at the public offering
price. Any Directed Shares not orally confirmed for purchase by any Participants
by the end of the first business day after the date on which this Agreement is
executed will be offered to the public by such Underwriters as set forth in the
Prospectus.

         1. Representations and Warranties of the Company. The Company
represents and warrants to and agrees with each of the Underwriters that:

                  (a) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, (1) the
         Company and its subsidiaries have not incurred any material liability
         or obligation, direct or contingent, nor entered into any material
         transaction not in the ordinary course of business; (2) the Company has
         not purchased any of its outstanding capital stock in any material
         amount nor declared, paid or otherwise made any dividend or
         distribution of any kind on its capital stock other than ordinary and
         customary dividends; and (3) there has not been any material change in
         the capital stock, short-term debt or long-term debt of the Company and
         its subsidiaries, except in each case as described in the Registration
         Statement or the Prospectus.

                  (b) The Company and its subsidiaries have good and valid title
         in fee simple to all real property and good and valid title to all
         personal property owned by them which is material to the business of
         the Company and its subsidiaries, in each case free and clear of all
         liens, encumbrances and defects except such as are described in the
         Prospectus or such as do not materially affect the value of such
         property and do not interfere with the use made and proposed to be made
         of such property by the Company and its subsidiaries; and any real
         property and buildings held under lease by the Company and its
         subsidiaries are held by them under valid, subsisting and enforceable
         leases with such exceptions as are not material and do not interfere
         with the use made and proposed to be made of such property and
         buildings by the Company and its subsidiaries, in each case except as
         described in the Prospectus.

                  (c) The Company and its subsidiaries own or possess adequate
         rights in, or can acquire adequate rights in, on reasonable terms, all
         material patents, patent rights, licenses, inventions, copyrights,
         know-how (including trade secrets and other unpatented


                                       -3-

   5




         or unpatentable proprietary or confidential information, systems or
         procedures), trademarks, service marks and trade names currently
         employed by them in connection with the business now operated by them,
         and neither the Company nor any of its subsidiaries has received any
         notice of infringement of or conflict with asserted rights of others
         with respect to any of the foregoing which, singly or in the aggregate,
         if the subject of an unfavorable decision, ruling or finding, would
         have a material adverse affect on the Company and its subsidiaries,
         taken as a whole.

                  (d) Except as described in the Prospectus, no material labor
         dispute with the employees of the Company or any of its subsidiaries
         exists, or, to the knowledge of the Company, is imminent;

                  (e) The Company and its subsidiaries are insured by the
         insurers of recognized financial responsibility against such losses and
         risks and in such amounts as are prudent and customary in the
         businesses in which they are engaged; neither the Company nor any of
         its subsidiaries (while a subsidiary of the Company) has been refused
         any insurance coverage sought or applied for; and neither the Company
         nor any of its subsidiaries has any reason to believe that it will not
         be able to renew its existing insurance coverage as and when such
         coverage expires or to obtain similar coverage from similar insurers as
         may be necessary to continue its business at a cost that would not have
         a material adverse effect on the Company and its subsidiaries, taken as
         a whole, except as described in the Prospectus.

                  (f) The Company and its subsidiaries possess all certificates,
         authorizations and permits issued by the appropriate federal, state or
         foreign regulatory authorities necessary to conduct their respective
         business except where the failure to possess such certificates,
         authorizations and permits would not have a material adverse effect on
         the Company and its subsidiaries taken as a whole, and neither the
         Company nor any of its subsidiaries has received any notice of
         proceedings relating to the revocation or modification of any such
         certificate, authorization or permit which, singly or in the aggregate,
         if the subject of an unfavorable decision, ruling or finding, would
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole, except as described the Prospectus.

                  (g) The Company and each of its subsidiaries maintain a system
         of internal accounting controls sufficient to provide reasonable
         assurance that (1) transactions are executed in accordance with
         management's general or specific authorizations; (2) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain asset accountability; (3) access to assets is permitted only
         in accordance with management's general or specific authorization; and
         (4) the recorded accountability for assets is compared with the
         existing assets at reasonable intervals and appropriate action is taken
         with respect to any differences.

         order suspending the effectiveness of the Registration Statement is in
         effect, and no proceedings for such purpose are pending before or, to
         the knowledge of the Company, threatened by the Commission.

                  (i) (i) The Registration Statement, when it became effective,
         did not contain and, as amended or supplemented, if applicable, will

         applicable rules and regulations of the Commission thereunder and (iii)
         the Prospectus does not contain and, as amended or supplemented, if
         applicable, will not contain any untrue statement of a material fact or
         omit to state a material fact necessary to make the statements therein,
         in the light of the circumstances under which they were made, not
         misleading, except that the representations and warranties set forth in
         this paragraph do not apply to statements or omissions in the
         Registration Statement or the Prospectus based upon information
         relating to any Underwriter furnished to the Company in writing by such

         authority to own its property and to conduct its business as described
         in the Prospectus and is duly qualified to transact business and is in
         good standing in each jurisdiction in which the conduct of its business
         or its ownership or leasing of property requires such qualification,
         except to the extent that the failure to be so qualified or be in good
         standing would not have a material adverse effect on the Company and
         its subsidiaries, taken as a whole.

                  (k) Each "significant subsidiary" of the Company within the

         be so qualified or be in good standing would not have a material
         adverse effect on the Company and its subsidiaries, taken as a whole;
         all of the issued shares of capital stock of each such significant
         subsidiary of the Company have been duly and validly authorized and

         material to the Company and its subsidiaries, taken as a whole, or any
         judgment, order or decree of any governmental body, agency or court

         so described or any statutes, regulations, contracts or other documents

         Prospectus or to be filed as exhibits to the Registration Statement
         that are not described or filed as required.

                  (s) Each preliminary prospectus filed as part of the
         registration statement as originally filed or as part of any amendment
         thereto, or filed pursuant to Rule 424 under the Securities Act,
         complied when so filed in all material respects with the Securities Act
         and the applicable rules and regulations of the Commission thereunder.

                  (t) The Company is not and, after giving effect to the
         offering and sale of the Shares and the application of the proceeds
         thereof as described in the Prospectus, will not be an "investment
         company" as such term is defined in the Investment Company Act of 1940,
         as amended.

                  (u) The Company and its subsidiaries (i) are in compliance
         with any and all applicable foreign, federal, state and local laws and
         regulations relating to the protection of human health and safety, the
         environment or hazardous or toxic substances or wastes, pollutants or
         contaminants ("ENVIRONMENTAL LAWS"), (ii) have received all permits,
         licenses or other approvals required of them under applicable
         Environmental Laws to conduct their respective businesses and (iii) are
         in compliance with all terms and conditions of any such permit, license
         or approval, except as described in the Prospectus or where such
         noncompliance with Environmental Laws, failure to receive required
         permits, licenses or other approvals or failure to comply with the
         terms and conditions of such permits, licenses or approvals would not,
         singly or in the aggregate, have a material adverse effect on the
         Company and its subsidiaries, taken as a whole.

                  (v) There are no costs or liabilities associated with
         Environmental Laws (including, without limitation, any capital or
         operating expenditures required for clean-up, closure of properties or
         compliance with Environmental Laws or any permit, license or approval,
         any related constraints on operating activities and any potential
         liabilities to third parties) which would, singly or in the aggregate,
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (w) There are no contracts, agreements or understandings
         between the Company and any person granting such person the right to
         require the Company to file a registration statement under the
         Securities Act with respect to any securities of the Company or to
         require the Company to include such securities with the Shares
         registered pursuant to the Registration Statement which has not been
         waived.

                  (x) The Company has reviewed its operations and that of its
         subsidiaries to evaluate the extent to which the business or operations
         of the Company or any of its subsidiaries will be affected by the Year
         2000 problem (that is, any significant risk that computer hardware or
         software applications used by the Company and its subsidiaries will
         not, in the case of dates or time periods occurring after December 31,
         1999, function at least as effectively as in the case of dates or time
         periods occurring prior to January 1, 2000) (the "YEAR 2000 PROBLEM");
         and as a result of such review, (i) the Company has no reason to
         believe, and does not believe, that (A) there are any issues related to
         the


                                       -7-

   9



         Company's preparedness to address the Year 2000 Problem that are of a
         character required to be described or referred to in the Registration
         Statement or Prospectus which have not been accurately described in the
         Registration Statement or Prospectus and (B) the Year 2000 Problem will
         have a material adverse effect on the condition, financial or
         otherwise, or on the earnings, business or operations of the Company
         and its subsidiaries, taken as a whole, or result in any material loss
         or interference with the business or operations of the Company and its
         subsidiaries, taken as a whole; and (ii) the Company reasonably
         believes, after due inquiry, that the suppliers, vendors, customers or
         other material third parties used or served by the Company and such
         subsidiaries are addressing or will address the Year 2000 Problem in a
         timely manner, except to the extent that a failure to address the Year
         2000 Problem by any supplier, vendor, customer or material third party
         would not have a material adverse effect on the condition, financial or
         otherwise, or on the earnings, business or operations of the Company
         and its subsidiaries, taken as a whole.

                  (y) Furthermore, the Company represents and warrants to Morgan
         Stanley and the Underwriters that are selling Shares pursuant to the
         Directed Share Program that (i) the Registration Statement, the
         Prospectus and any preliminary prospectus comply, and any further
         amendments or supplements thereto will comply, with any applicable laws
         or regulations of foreign jurisdictions in which the Prospectus or any
         preliminary prospectus, as amended or supplemented, if applicable, are
         distributed at the request of the Company in connection with the
         Directed Share Program, and (ii) no authorization, approval, consent,
         license, order, registration or qualification of or with any
         government, governmental instrumentality or court, other than such as
         have been obtained, is necessary under the securities laws and
         regulations of foreign jurisdictions in which the Directed Shares are
         offered outside the United States at the request of the Company.

                  (z) The Company has not offered, or caused the Underwriters to
         offer, Shares to any person pursuant to the Directed Share Program with
         the specific intent to unlawfully influence (i) a customer or supplier
         of the Company to alter the customer's or supplier's level or type of
         business with the Company, or (ii) a trade journalist or publication to
         write or publish favorable information about the Company or its
         products.

         2. Representations and Warranties of the Selling Stockholders. Each of

                  The several obligations of the U.S. Underwriters to purchase
         Additional Shares hereunder are subject to the delivery to the U.S.
         Representatives on the Option Closing Date of such documents as the
         U.S. Representatives may reasonably request with respect to the good
         standing of the Company, the due authorization and issuance of the
         Additional Shares and other matters related to the issuance of the
         Additional Shares.

         7. Covenants of the Company. In further consideration of the agreements
of the Underwriters herein contained, the Company covenants with each
Underwriter as follows:

                  (a) To furnish to you, without charge, such number of signed
         copies of the Registration Statement (including exhibits thereto) as
         you may reasonably request and for delivery to each other Underwriter a
         conformed copy of the Registration Statement (without exhibits thereto)
         and to furnish to you in New York City, without charge, prior to 5:00
         p.m. New York City time on the business day next succeeding the date of
         this Agreement and during the period mentioned in Section 7(c) below,
         as many copies of the Prospectus and any supplements and amendments
         thereto or to the Registration Statement as you may reasonably request.

                  (b) Before amending or supplementing the Registration
         Statement or the Prospectus, to furnish to you a copy of each such
         proposed amendment or supplement and not to file any such proposed
         amendment or supplement to which you reasonably object, and to file
         with the Commission within the applicable period specified in Rule
         424(b) under the Securities Act any prospectus required to be filed
         pursuant to such Rule.


                                      -21-

   23



                  (c) If, during such period after the first date of the public
         offering of the Shares as in the opinion of counsel for the
         Underwriters the Prospectus is required by law to be delivered in
         connection with sales by an Underwriter or dealer, any event shall
         occur or condition exist as a result of which it is necessary to amend
         or supplement the Prospectus in order to make the statements therein,
         in the light of the circumstances when the Prospectus

         is delivered to a purchaser, not misleading, or if, in the opinion of
         counsel for the Underwriters, it is necessary to amend or supplement
         the Prospectus to comply with applicable law, forthwith to prepare,
         file with the Commission and furnish, at its own expense, to the
         Underwriters and to the dealers (whose names and addresses you will
         furnish to the Company) to which Shares may have been sold by you on
         behalf of the Underwriters and to any other dealers upon request,
         either amendments or supplements to the Prospectus so that the
         statements in the Prospectus as so amended or supplemented will not, in
         the light of the circumstances when the Prospectus is delivered to a
         purchaser, be misleading or so that the Prospectus, as amended or
         supplemented, will comply with law.

                  (d) To endeavor to qualify the Shares for offer and sale under
         the securities or blue sky laws of such jurisdictions as you shall
         reasonably request; provided, however, that the Company shall not be
         obligated (i) to qualify as a foreign corporation in any jurisdiction
         in which it is not so qualified, (ii) to take any action that would
         subject it to taxation in any jurisdiction or (iii) to execute a
         consent to service of process under the laws of any jurisdiction
         (except service of process with respect to the offering and sale of
         Shares).

                  (e) To make generally available to the Company's security
         holders and to you as soon as practicable an earning statement covering
         the twelve-month period ending [SEPTEMBER 30,] 2000 that satisfies the
         provisions of Section 11(a) of the Securities Act and the rules and
         regulations of the Commission thereunder.

                  (f) That in connection with the Directed Share Program, the
         Company will ensure that the Directed Shares will be restricted to the
         extent required by the National Association of Securities Dealers, Inc.
         (the "NASD") or the NASD rules from sale, transfer, assignment, pledge
         or hypothecation for a period of three months following the date of the
         effectiveness of the Registration Statement. Morgan Stanley will notify
         the Company as to which Participants will need to be so restricted. The
         Company will direct the transfer agent of the Common Stock to place
         stop transfer restrictions upon such securities for such period of
         time.

                  (g) To pay all fees and disbursements of Belgian, Canadian and
         Australian counsel incurred by the Underwriters in connection with the
         Directed Share Program and stamp duties, similar taxes or duties or
         other taxes, if any, incurred by the Underwriters in connection with
         the Directed Share Program.



                                      -22-

   24



                  (h) Furthermore, the Company covenants with Morgan Stanley
         that the Company will comply with all applicable securities and other
         applicable laws, rules and regulations in each foreign jurisdiction in
         which the Directed Shares are offered in connection with the Directed
         Share Program.

         8. Expenses. Whether or not the transactions contemplated in this
Agreement are consummated or this Agreement is terminated, the Sellers agree to
pay or cause to be paid all expenses incident to the performance of their
obligations under this Agreement, including: (i) the fees, disbursements and
expenses of the Company's counsel, the Company's accountants and counsel for the
Selling Stockholders in connection with the registration and delivery of the
Shares under the Securities Act and all other fees or expenses in connection
with the preparation and filing of the Registration Statement, any preliminary
prospectus, the Prospectus and amendments and supplements to any of the
foregoing, including all printing costs associated therewith, and the mailing
and delivering of copies thereof to the Underwriters and dealers, in the
quantities hereinabove specified, (ii) all costs and expenses related to the
transfer and delivery of the Shares to the Underwriters, including any transfer
or other taxes payable thereon, (iii) the cost of printing or producing any blue
sky or legal investment memorandum in connection with the offer and sale of the
Shares under state securities laws and all expenses in connection with the
qualification of the Shares for offer and sale under state securities laws as
provided in Section 7(d) hereof, including filing fees and the reasonable fees
(not in excess of $2,000) and disbursements of counsel for the Underwriters in
connection with such qualification and in connection with the blue sky or legal
investment memorandum, (iv) all filing fees and the fees (not in excess of
$7,500) and reasonable disbursements of counsel to the Underwriters (including
counsel fees incurred on behalf of or disbursements by Morgan Stanley in its
capacity as a "qualified independent underwriter") incurred in connection with
the review and qualification of the offering of the Shares by the NASD, (v) all
fees and expenses incurred in connection with the preparation and filing of the
registration statement on Form 8-A relating to the Common Stock and all costs
and expenses incident to listing the Shares on the New York Stock Exchange and
other national securities exchanges and foreign stock exchanges, (vi) the cost
of printing certificates representing the Shares, (vii) the costs and charges of
any transfer agent, registrar or depositary of the Shares, (viii) the costs and
expenses of the Company relating to investor presentations on any "road show"
undertaken in connection with the marketing of the offering of the Shares,
including, without limitation, expenses associated with the production of road
show slides and graphics, fees and expenses of any consultants engaged in
connection with the road show presentations with the prior approval of the
Company, travel and lodging expenses of the representatives and officers of the
Company and any such consultants, and the cost of any aircraft chartered in
connection with the road show, (ix) all fees and disbursements of Belgian,
Canadian and Australian counsel incurred by the Underwriters in connection with
the Directed Share Program and stamp duties, similar taxes or duties or other
taxes, if any, incurred by the Underwriters in connection with the Directed
Share Program, and (x) all other costs and expenses incident to the performance
of the obligations of the Company hereunder for which provision is not otherwise
made in this Section. It is understood, however, that, except as


                                      -23-

   25



provided in this Section, Section 9, and the last paragraph of Section 11 below,
the Underwriters will pay all of their costs and expenses, including fees and
disbursements of their counsel, stock transfer taxes payable on resale of any of
the Shares by them and any advertising expenses connected with any offers they
may make.

         The provisions of this Section shall not supersede or otherwise affect
any agreement that the Sellers may otherwise have for the allocation of such
expenses among themselves.

         9.       Indemnity and Contribution.

                  (a) The Company agrees to indemnify and hold harmless each
         Underwriter and each person, if any, who controls any Underwriter
         within the meaning of either Section 15 of the Securities Act or
         Section 20 of the Securities Exchange Act of 1934, as amended (the
         "EXCHANGE ACT"), from and against any and all losses, claims, damages
         and liabilities (including, without limitation, any legal or other
         expenses reasonably incurred in connection with defending or
         investigating any such action or claim) caused by any untrue statement
         or alleged untrue statement of a material fact contained in the
         Registration Statement or any amendment thereof, any preliminary
         prospectus or the Prospectus (as amended or supplemented if the Company
         shall have furnished any amendments or supplements thereto), or caused
         by any omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, except insofar as such losses, claims, damages
         or liabilities are caused by any such untrue statement or omission or
         alleged untrue statement or omission based upon information relating to
         any Underwriter furnished to the Company in writing by such Underwriter
         through you expressly for use therein; provided, however, that the
         foregoing indemnity agreement with respect to any preliminary
         prospectus shall not inure to the benefit of any Underwriter from whom
         the person asserting any such losses, claims, damages or liabilities
         purchased Shares, or any person controlling such Underwriter, if a copy
         of the Prospectus (as then amended or supplemented if the Company shall
         have furnished any amendments or supplements thereto) was not sent or
         given by or on behalf of such Underwriter to such person, if required
         by law so to have been delivered, at or prior to the written
         confirmation of the sale of the Shares to such person, and if the
         Prospectus (as so amended or supplemented) would have cured the defect
         giving rise to such losses, claims, damages or liabilities, unless such
         failure is the result of noncompliance by the Company with Section 7(a)
         hereof.

                  The Company also agrees to indemnify and hold harmless Morgan
         Stanley & Co. Incorporated ("MORGAN STANLEY") and each person, if any,
         who controls Morgan Stanley within the meaning of either Section 15 of
         the Act or Section 20 of the Exchange Act from and against any and all
         losses, claims, damages, liabilities and judgments incurred as a result
         of Morgan Stanley's participation as a "qualified independent
         underwriter" within the meaning of Rule 2720 of the National
         Association of Securities Dealers'


                                      -24-

   26




         Conduct Rules in connection with the offering of the Shares, except
         for any losses, claims, damages, liabilities and judgments resulting
         from Morgan Stanley's, or such controlling person's, willful
         misconduct.

                  (b) The Company agrees to indemnify and hold harmless Morgan
         Stanley, each other Underwriter that sells Shares pursuant to the
         Directed Share Program and each of their affiliates (including each
         person, if any, that controls Morgan Stanley or such Underwriter within
         the meaning of either Section 15 of the Securities Act or Section 20 of
         the Exchange Act) (collectively, the "DIRECTED SHARE UNDERWRITERS")
         from and against any and all losses, claims, damages and liabilities
         (including, without limitation, any legal or other expenses reasonably
         incurred in connection with defending or investigating any such action
         or claim) (i) caused by any untrue statement or alleged untrue
         statement of a material fact contained in the prospectus wrapper
         material prepared by or with the consent of the Company for
         distribution in foreign jurisdictions in connection with the Directed
         Share Program attached to the Prospectus or any preliminary prospectus,
         or caused by any omission or alleged omission to state therein a
         material fact required to be stated therein or necessary to make the
         statement therein, when considered in conjunction with the Prospectus
         or any applicable preliminary prospectus, not misleading; (ii) caused
         by the failure of any Participant to pay for and accept delivery of the
         shares which, immediately following the effectiveness of the
         Registration Statement, were subject to a properly confirmed agreement
         to purchase; or (iii) related to, arising out of, or in connection with
         the Directed Share Program, provided that the Company shall not be
         responsible under this subparagraph (iii) for any losses, claims,
         damages or liabilities (or expenses relating thereto) that are finally
         judicially determined to have resulted from the bad faith or gross
         negligence of Directed Share Underwriters; provided, however, that the
         foregoing indemnity agreement with respect to any preliminary
         prospectus shall not inure to the benefit of any Directed Share
         Underwriter from whom the person asserting any such losses, claims,
         damages or liabilities purchased Shares, or any affiliate of such
         Directed Share Underwriter, if a copy of the Prospectus (as then
         amended or supplemented if the Company shall have furnished any
         amendments or supplements thereto) was not sent or given by or on
         behalf of such Directed Share Underwriter to such person, if required
         by law so to have been delivered, at or prior to the written
         confirmation of the sale of the Shares to such person, and if the
         Prospectus (as so amended or supplemented) would have cured the defect
         giving rise to such losses, claims, damages or liabilities, unless such
         failure is the result of noncompliance by the Company with Section 7(a)
         hereof.

                  (c) Each Selling Stockholder agrees, severally and not
         jointly, to indemnify and hold harmless each Underwriter and each
         person, if any, who controls any Underwriter within the meaning of
         either Section 15 of the Securities Act or Section 20 of the Exchange
         Act, from and against any and all losses, claims, damages and
         liabilities (including, without limitation, any legal or other expenses
         reasonably incurred in connection with defending or investigating any
         such action or claim) caused by any



                                      -25-

   27




         untrue statement or alleged untrue statement of a material fact
         contained in the Registration Statement or any amendment thereof, any
         preliminary prospectus or the Prospectus (as amended or supplemented if
         the Company shall have furnished any amendments or supplements
         thereto), or caused by any omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein not misleading, but only with reference to
         information relating to such Selling Stockholder furnished to the
         Company in writing by or on behalf of such Selling Stockholder
         expressly for use in the Registration Statement, any preliminary
         prospectus, the Prospectus or any amendments or supplements thereto;
         provided, however, that the foregoing indemnity agreement with respect
         to any preliminary prospectus shall not inure to the benefit of any
         Underwriter from whom the person asserting any such losses, claims,
         damages or liabilities purchased Shares, or any person controlling such
         Underwriter, if a copy of the Prospectus (as then amended or
         supplemented if the Company shall have furnished any amendments or
         supplements thereto) was not sent or given by or on behalf of such
         Underwriter to such person, if required by law so to have been
         delivered, at or prior to the written confirmation of the sale of the
         Shares to such person, and if the Prospectus (as so amended or
         supplemented) would have cured the defect giving rise to such losses,
         claims, damages or liabilities, unless such failure is the result of
         noncompliance by the Company with Section 7(a) hereof; provided,
         further, however, that with respect to any amount due an indemnified
         person under this paragraph (c), each Selling Stockholder shall be
         liable only to the extent of the net proceeds received by such Selling
         Stockholder from such Selling Stockholder's Shares.

                  (d) Each Underwriter agrees, severally and not jointly, to
         indemnify and hold harmless the Company, the Selling Stockholders, the
         directors of the Company, the officers of the Company who sign the
         Registration Statement and each person, if any, who controls the
         Company or any Selling Stockholder within the meaning of either Section
         15 of the Securities Act or Section 20 of the Exchange Act from and
         against any and all losses, claims, damages and liabilities (including,
         without limitation, any legal or other expenses reasonably incurred in
         connection with defending or investigating any such action or claim)
         caused by any untrue statement or alleged untrue statement of a
         material fact contained in the Registration Statement or any amendment
         thereof, any preliminary prospectus or the Prospectus (as amended or
         supplemented if the Company shall have furnished any amendments or
         supplements thereto), or caused by any omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, but only with
         reference to information relating to such Underwriter furnished to the
         Company in writing by or on behalf of such Underwriter through you
         expressly for use in the Registration Statement, any preliminary
         prospectus, the Prospectus or any amendments or supplements thereto.

                  (e) In case any proceeding (including any governmental
         investigation) shall be instituted involving any person in respect of
         which indemnity may be sought pursuant to Section 9(a), 9(b), 9(c) or
         9(d), such person (the "INDEMNIFIED PARTY") shall promptly


                                      -26-

   28




         notify the person against whom such indemnity may be sought (the
         "INDEMNIFYING PARTY") in writing and the indemnifying party, upon
         request of the indemnified party, shall retain counsel reasonably
         satisfactory to the indemnified party to represent the indemnified
         party and any others the indemnifying party may designate in such
         proceeding and shall pay the fees and disbursements of such counsel
         related to such proceeding. In any such proceeding, any indemnified
         party shall have the right to retain its own counsel, but the fees and
         expenses of such counsel shall be at the expense of such indemnified
         party unless (i) the indemnifying party and the indemnified party shall
         have mutually agreed to the retention of such counsel or (ii) the named
         parties to any such proceeding (including any impleaded parties)
         include both the indemnifying party and the indemnified party and
         representation of both parties by the same counsel would be
         inappropriate due to actual or potential differing interests between
         them. It is understood that the indemnifying party shall not, in
         respect of the legal expenses of any indemnified party in connection
         with any proceeding or related proceedings in the same jurisdiction, be
         liable for (x) the fees and expenses of more than one separate firm (in
         addition to any local counsel) for all Underwriters and all persons, if
         any, who control any Underwriter within the meaning of either Section
         15 of the Securities Act or Section 20 of the Exchange Act, (y) the
         fees and expenses of more than one separate firm (in addition to any
         local counsel) for the Company, its directors, its officers who sign
         the Registration Statement and each person, if any, who controls the
         Company within the meaning of either such Section and (z) the fees and
         expenses of more than one separate firm (in addition to any local
         counsel) for all Selling Stockholders and all persons, if any, who
         control any Selling Stockholder within the meaning of either such
         Section, and that all such fees and expenses shall be reimbursed as
         they are incurred. Notwithstanding anything contained herein to the
         contrary, if indemnity may be sought pursuant to the second paragraph
         of Section 9(a) hereof in respect of such action or proceeding, then in
         addition to such separate firm for the indemnified parties, the
         indemnifying party shall be liable for the reasonable fees and expenses
         of not more than one separate firm (in addition to any local counsel)
         for Morgan Stanley in its capacity as a "qualified independent
         underwriter" and all persons, if any, who control Morgan Stanley within
         the meaning of either Section 15 of the Act or Section 20 of the
         Exchange Act. In the case of any such separate firm for the
         Underwriters and such control persons of any Underwriters, such firm
         shall be designated in writing by Morgan Stanley. In the case of any
         such separate firm for the Company, and such directors, officers and
         control persons of the Company, such firm shall be designated in
         writing by the Company. In the case of any such separate firm for the
         Selling Stockholders and such control persons of any Selling
         Stockholders, such firm shall be designated in writing by the persons
         named as attorneys-in-fact for the Selling Stockholders under the
         Powers of Attorney. The indemnifying party shall not be liable for any
         settlement of any proceeding effected without its written consent, but
         if settled with such consent or if there be a final judgment for the
         plaintiff, the indemnifying party agrees to indemnify the indemnified
         party from and against any loss or liability by reason of such
         settlement or judgment. No indemnifying party shall, without the prior
         written consent of the indemnified party, effect any settlement of any
         pending or


                                      -27-

   29




         threatened proceeding in respect of which any indemnified party is or
         could have been a party and indemnity could have been sought hereunder
         by such indemnified party, unless such settlement includes an
         unconditional release of such indemnified party from all liability on
         claims that are the subject matter of such proceeding.

                  (f) To the extent the indemnification provided for in Section
         9(a), 9(b), 9(c) or 9(d) is unavailable to an indemnified party or
         insufficient in respect of any losses, claims, damages or liabilities
         referred to therein, then each indemnifying party under such paragraph,
         in lieu of indemnifying such indemnified party thereunder, shall
         contribute to the amount paid or payable by such indemnified party as a
         result of such losses, claims, damages or liabilities (i) in such
         proportion as is appropriate to reflect the relative benefits received
         by the indemnifying party or parties on the one hand and the
         indemnified party or parties on the other hand from the offering of the
         Shares or (ii) if the allocation provided by clause 9(f)(i) above is
         not permitted by applicable law, in such proportion as is appropriate
         to reflect not only the relative benefits referred to in clause 9(f)(i)
         above but also the relative fault of the indemnifying party or parties
         on the one hand and of the indemnified party or parties on the other
         hand in connection with the statements or omissions that resulted in
         such losses, claims, damages or liabilities, as well as any other
         relevant equitable considerations. The relative benefits received by
         the Sellers on the one hand and the Underwriters on the other hand in
         connection with the offering of the Shares shall be deemed to be in the
         same respective proportions as the net proceeds from the offering of
         the Shares (before deducting expenses) received by each Seller and the
         total underwriting discounts and commissions received by the
         Underwriters, in each case as set forth in the table on the cover of
         the Prospectus, bear to the aggregate Public Offering Price of the
         Shares. The relative fault of the Sellers on the one hand and the
         Underwriters on the other hand shall be determined by reference to,
         among other things, whether the untrue or alleged untrue statement of a
         material fact or the omission or alleged omission to state a material
         fact relates to information supplied by the Sellers or by the
         Underwriters and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The Underwriters' respective obligations to contribute
         pursuant to this Section 9 are several in proportion to the respective
         number of Shares they have purchased hereunder, and not joint.

                  (g) The Sellers and the Underwriters agree that it would not
         be just or equitable if contribution pursuant to this Section 9 were
         determined by pro rata allocation (even if the Underwriters were
         treated as one entity for such purpose) or by any other method of
         allocation that does not take account of the equitable considerations
         referred to in Section 9(f). The amount paid or payable by an
         indemnified party as a result of the losses, claims, damages and
         liabilities referred to in the immediately preceding paragraph shall be
         deemed to include, subject to the limitations set forth above, any
         legal or other expenses reasonably incurred by such indemnified party
         in connection with investigating or defending any such action or claim.
         Notwithstanding the provisions of this Section 9,


                                      -28-

   30




         (i) no Underwriter shall be required to contribute any amount in excess
         of the amount by which the total price at which the Shares underwritten
         by it and distributed to the public were offered to the public exceeds
         the amount of any damages that such Underwriter has otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission or alleged omission and (ii) no Selling Stockholder shall be
         required to contribute any amount in excess of the amount by which the
         proceeds received by such Selling Stockholder in connection herewith
         exceed the aggregate amount such Selling Stockholder has otherwise been
         requested to pay pursuant hereto. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation. The remedies
         provided for in this Section 9 are not exclusive and shall not limit
         any rights or remedies which may otherwise be available to any
         indemnified party at law or in equity.

                  (h) The indemnity and contribution provisions contained in
         this Section 9 and the representations, warranties and other statements
         of the Company and the Selling Stockholders contained in this Agreement
         shall remain operative and in full force and effect regardless of (i)
         any termination of this Agreement, (ii) any investigation made by or on
         behalf of any Underwriter, any person controlling any Underwriter, any
         affiliate of any Underwriter that is selling Shares pursuant to the
         Directed Share Program, any Selling Stockholder or any person
         controlling any Selling Stockholder, or the Company, its officers or
         directors or any person controlling the Company and (iii) acceptance of
         and payment for any of the Shares.

         10. Termination. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange, the National Association
of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago
Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any
securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in your judgment, is material and adverse and (b) in the case of any of
the events specified in clauses 10(a)(i) through 10(a)(iv), such event, singly
or together with any other such event, makes it, in your judgment, impracticable
to market the Shares on the terms and in the manner contemplated in the
Prospectus.

         11. Effectiveness; Defaulting Underwriters. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

         If, on the Closing Date or the Option Closing Date, as the case may be,
any one or more


                                      -29-

   31



of the Underwriters shall fail or refuse to purchase Shares that it has or they
have agreed to purchase hereunder on such date, and the aggregate number of
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase is not more than one-tenth of the aggregate number of the
Shares to be purchased on such date, the other Underwriters shall be obligated
severally in the proportions that the number of Firm Shares set forth opposite
their respective names in Schedule II and Schedule III bears to the aggregate
number of Firm Shares set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as you may specify, to purchase the
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase on such date; provided that in no event shall the number of
Shares that any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 11 by an amount in excess of one-ninth of
such number of Shares without the written consent of such Underwriter. If, on
the Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of Firm
Shares to be purchased, and arrangements satisfactory to you, the Company and
the Selling Stockholders for the purchase of such Firm Shares are not made
within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter, the Company or the
Selling Stockholders. In any such case either you or the relevant Sellers shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected. If, on the Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased, the
non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase Additional Shares or (ii) purchase not less
than the number of Additional Shares that such non-defaulting Underwriters would
have been obligated to purchase in the absence of such default. Any action taken
under this paragraph shall not relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

         If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of any Seller to comply with
the terms or to fulfill any of the conditions of this Agreement, or if for any
reason any Seller shall be unable to perform its obligations under this
Agreement, the Sellers will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

         12. Counterparts. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         13. Applicable Law. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

         14. Headings. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of

Ladies and Gentlemen:

         The undersigned understands that Morgan Stanley & Co. Incorporated and
Morgan Stanley & Co. International Limited (collectively "MORGAN STANLEY")
propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT")
with Lennox International Inc., a Delaware corporation (the "COMPANY"),
providing for the public offering (the "PUBLIC OFFERING") by the several
Underwriters, including Morgan Stanley (the "UNDERWRITERS"), of ______________
shares (the "SHARES") of the common stock, par value $.01 per share, of the
Company (the "COMMON STOCK").

         To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period commencing
on the date hereof and ending 180 days after the date of the final prospectus
relating to the Public Offering (the "PROSPECTUS"), (1) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, lend or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock or (2) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
Common Stock, whether any such transaction described in clause (1) or (2) above
is to be settled by delivery of Common Stock or such other securities, in cash
or otherwise; PROVIDED, HOWEVER, that the undersigned shall be permitted to make
a bona fide gift of shares of Common Stock during such period if the undersigned
delivers to Morgan Stanley a letter substantially similar to this letter
executed by the donee. The foregoing sentence shall not apply to (a) the sale of
any Shares to the Underwriters pursuant to the Underwriting Agreement or (b)
transactions relating to shares of Common Stock or other securities acquired in
open market transactions after the completion of the Public Offering. In
addition, the undersigned agrees that, without the prior written consent of
Morgan Stanley on behalf of the Underwriters, it will not, during the period
commencing on the date

   37



hereof and ending 180 days after the date of the Prospectus, make any demand for
or exercise any right with respect to, the registration of any shares of Common
Stock or any security convertible into or exercisable or exchangeable for Common
Stock.

         Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.

                                            Very truly yours,
