GENERAL INFORMATION REGARDING THE 2007
ANNUAL MEETING OF STOCKHOLDERS
 
Meeting Date and Location
 
The 2007 Annual Meeting of Stockholders will be held on May 17, 2007 at 9:00 a.m., local time, at the University of Texas at Dallas School of Management, southeast corner of Drive A and University Parkway, Richardson, Texas 75083. We began mailing this Proxy Statement and the accompanying Notice of Annual Meeting of Stockholders, Proxy Card, Annual Report to Stockholders and Annual Report on Form 10-K to our stockholders on or about April   , 2007 for the purpose of soliciting proxies on behalf of our Board of Directors.
 
Meeting Agenda
 
At the meeting, you will be asked to elect five Class III directors to hold office for a three-year term expiring at the 2010 Annual Meeting of Stockholders, approve the issuance of shares of our common stock pursuant to an Agreement and Plan of Reorganization with A.O.C. Corporation and to transact any other business that is properly brought before the meeting.
 
Record Versus Beneficial Ownership of Shares
 
If your shares are registered directly in your name with our transfer agent, Mellon Investor Services LLC, you are considered, with respect to those shares, the “stockholder of record.” If you are a stockholder of record, we sent our Notice of Annual Meeting of Stockholders, Proxy Statement, Proxy Card, Annual Report to Stockholders and Annual Report on Form 10-K directly to you.
 
If your shares are held in a stock brokerage account or by a bank or other holder of record, you are considered the “beneficial owner” of shares held in street name. In that case, our Notice of Annual Meeting of Stockholders, Proxy Statement, Proxy Card, Annual Report to Stockholders and Annual Report on Form 10-K have been forwarded to you by your broker, bank or other holder of record who is considered, with respect to those shares, the stockholder of record. Your broker, bank or other holder of record will also send you instructions on how to vote. If you have not heard from your broker, bank or other holder of record who holds your stock, please contact them as soon as possible.
 
Record Date and Number of Votes
 
The record date for the 2007 Annual Meeting of Stockholders is March 26, 2007. If you were a stockholder of record at the close of business on March 26, 2007, you may vote at the meeting. At the close of business on the record date, there were           shares of our common stock outstanding and entitled to vote and approximately           stockholders of record. Each stockholder is entitled to one vote per share.
 
Quorum and Vote Required
 
A quorum is required to transact business at the meeting. To achieve a quorum at the meeting, stockholders holding a majority of our outstanding shares entitled to vote must be present either in person or represented by proxy. Shares held by us in treasury will not count towards a quorum. However, abstentions and “broker non-votes” will be counted as present and entitled to vote for purposes of determining a quorum. A “broker non-vote” occurs when a bank, broker or other holder of record holding shares for a beneficial owner does not vote on a particular proposal because that holder does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner. In the event a quorum is not present at the meeting, we expect the meeting will be adjourned or postponed to solicit additional proxies.
 
To be elected, nominees for director must receive a plurality of the votes cast. This means that the director nominees with the most votes are elected, regardless of whether any nominee received a majority of votes cast. An affirmative vote of the majority of the votes cast (provided that the total votes cast in respect of the proposal represent more than 50% of all of our outstanding common stock entitled to vote thereon) is

Table of Contents

required for approval of the issuance of shares of our common stock pursuant to an Agreement and Plan of Reorganization with A.O.C. Corporation. Any other matters submitted to you at the meeting will be decided by a majority of the votes cast.
 
If you are a beneficial owner, your bank, broker or other holder of record has discretionary authority to vote your shares on the election of directors even if the bank, broker or other holder of record does not receive voting instructions from you. However, your bank, broker or other holder of record does not have authority to vote your shares to approve the issuance of shares of our common stock pursuant to an Agreement and Plan of Reorganization with A.O.C. Corporation without written instructions from you. Neither abstentions nor broker non-votes will be counted as votes cast “for” or “against” any of the proposals.
 
A representative of our transfer agent will tabulate the votes and act as inspector of election at the meeting.
 
Voting Procedures
 
To be sure your shares are represented at the Annual Meeting of Stockholders, please vote as soon as possible by using one of the following methods:
 
  •    By Mail:  You may complete, date, sign and return your Proxy Card in the enclosed postage-paid envelope. If you sign and return the accompanying Proxy Card and your proxy is not revoked, your shares will be voted in accordance with your voting instructions. If you sign and return your Proxy Card but do not give voting instructions, your shares will be voted as recommended by the Board of Directors.
 
  •    By Telephone or Internet:  The telephone and Internet voting procedures established by our company and administered by our transfer agent are available to our stockholders of record only. If you are a stockholder of record, you can vote by calling the toll-free number (866) 540-5760 and following the prompts or by Internet at www.proxyvoting.com/lii. You should have your Proxy Card in hand when you call or access the website. Telephone and Internet voting for stockholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern Time, on May 16, 2007.
 
If you are the beneficial owner of shares held in a stock brokerage account or by a bank or other holder of record, you will not be able to vote by calling the phone number or accessing the Internet address provided above. The availability of telephone and Internet voting for beneficial owners will depend on the voting procedures of your broker, bank or other holder of record. These procedures differ from the procedures provided by our transfer agent for stockholders of record. Therefore, you should check the information forwarded to you by your broker, bank or other holder of record to find out which voting options are available to you.
 
If you vote by telephone or Internet and your proxy is not revoked, your shares will be voted in accordance with your voting instructions and you do not need to return your Proxy Card.
 
  •    In Person at the Annual Meeting of Stockholders:  You may vote in person at the meeting even if you send in your Proxy Card, vote by telephone or vote by Internet. The ballot you submit at the meeting will supersede any prior vote. If you attend the Annual Meeting of Stockholders in person and want to vote shares you beneficially hold in street name, you must bring a written proxy from your broker, bank or other holder of record that identifies you as the sole representative entitled to vote the shares indicated.
 
Changing Your Vote
 
You can change your vote on a proposal at any time before the meeting for any reason by revoking your proxy. Proxies may be revoked by filing a written notice of revocation, which includes a later date than the proxy date, with our Corporate Secretary at or before the meeting. Proxies may also be revoked by:
 
  •    submitting a new written proxy bearing a later date than the Proxy Card you previously submitted prior to or at the Annual Meeting of Stockholders;


2


Table of Contents

 
  •    voting again by telephone or Internet before 11:59 p.m., Eastern Time, on May 16, 2007; or
 
  •    attending the Annual Meeting of Stockholders and voting in person; however, attendance at the meeting will not in and of itself constitute a revocation of your proxy.
 
In each case, the later submitted vote will be recorded and the earlier vote revoked. Any written notice of a revocation of a proxy should be sent to Lennox International Inc., 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Corporate Secretary. To be effective, the revocation must be received by our Corporate Secretary before the taking of the vote at the Annual Meeting of Stockholders.
 
Other Business; Adjournments
 
We are not aware of any other business to be acted upon at the 2007 Annual Meeting of Stockholders. If, however, other matters are properly brought before the meeting, or any reconvened meeting after any adjournment or postponement thereof, the persons named in the accompanying Proxy Card will have discretion to act on those matters according to their best judgment. In the absence of a quorum, stockholders representing a majority of the votes present in person or by proxy at the meeting may adjourn the meeting.

PROPOSAL 2:
APPROVAL OF THE ISSUANCE OF SHARES OF OUR COMMON STOCK PURSUANT TO AN AGREEMENT AND PLAN OF REORGANIZATION WITH A.O.C. CORPORATION
 
The Proposal and Background of the Transaction
 
We are seeking stockholder approval for a proposal to issue up to 2,239,589 shares of our common stock pursuant to an Agreement and Plan of Reorganization, dated March 16, 2007 (the “Reorganization Agreement”), between our company and A.O.C. Corporation (“AOC”), a copy of which is attached as Exhibit A to this Proxy Statement. We will issue these shares in exchange for 2,695,770 shares of our common stock owned by AOC, which will result in a reduction in the number of outstanding shares of our common stock by up to 456,181 shares at minimal cost to us. Consummation of the transaction is subject to the satisfaction of certain conditions, including obtaining approval by the holders of our common stock of the issuance of up to 2,239,589 shares of our common stock as described in more detail below.

Table of Contents

 
AOC is the legal successor to the Armstrong Ohio Corporation, which was in the business of manufacturing furnaces and other heating appliances. In the late 1950s, Armstrong Ohio Corporation sold its assets and invested the cash proceeds in marketable securities. Through the years, AOC sold the marketable securities and used the proceeds to purchase the then privately held shares of our common stock from the AOC stockholders and our management when such persons desired to sell shares of our common stock for cash. AOC’s assets consist solely of 2,695,770 shares of our common stock and cash. AOC would like to collapse its structure so that its assets are owned directly by its shareholders.
 
In order to achieve this objective, Thomas W. Booth, the President of AOC and a director of our company and Vice President of Operations of Services of Service Experts Inc., one of our subsidiaries, submitted a proposal, by letter dated August 22, 2005, to Robert E. Schjerven, our Chief Executive Officer at that time. The August 22 letter proposed to undertake a restructuring of AOC (the “AOC Restructuring”), whereby AOC would transfer 2,695,770 shares of our common stock in exchange for 2,395,770 shares of our common stock. Following this transfer, AOC would liquidate and distribute the shares of our common stock to its shareholders. AOC’s proposal stated that this transaction is intended to qualify as a tax-free reorganization under Section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended, which means that no gain or loss would be recognized by the AOC shareholders when they receive shares of our common stock upon liquidation of AOC. The proposal also provided that consummation of the AOC Restructuring would be contingent upon obtaining a private letter ruling from the Internal Revenue Service that the transaction would qualify as a tax-free reorganization.
 
On September 16, 2005, Linda G. Alvarado, James J. Byrne, Janet K. Cooper, C.L. (Jerry) Henry, John E. Major, Walden W. O’Dell, Paul W. Schmidt, Terry D. Stinson and Richard L. Thompson, the disinterested members of our Board of Directors at that time, met with Mr. Schjerven, Susan K. Carter, our Chief Financial Officer, and William F. Stoll, Jr., our Chief Legal Officer, to review the proposal from AOC. The disinterested directors discussed the proposal and asked management to research certain issues and report their findings to Mr. Thompson. On October 10, 2005, Mr. Stoll met with Mr. Thompson by telephone to report management’s findings. Subsequent to that meeting, it was decided not to pursue the AOC Restructuring at that time for reasons primarily related to corporate priorities and not the merits of the transaction. On October 12, 2005, Mr. Stoll transmitted a letter to Mr. Booth, which advised AOC that we did not believe it to be in our best interests to entertain AOC’s proposal at that time.
 
On October 23, 2006, Mr. Booth submitted to Mr. Schjerven a second proposal for the AOC Restructuring that was substantially identical to the prior proposal submitted on August 22, 2005. Management of our company discussed the transaction with Mr. Thompson who authorized the commencement of preliminary discussions with AOC and the transmittal of a response to AOC. On November 17, 2006, on behalf of our disinterested directors, Mr. Stoll delivered a letter to Mr. Booth in which he stated that the consideration that AOC proposed to be paid by us in the AOC Restructuring (2,395,770 shares of our common stock) was excessive in light of the efforts required by us and the benefits to be received by AOC. Mr. Stoll’s letter proposed instead that we pay 2,223,770 shares of our common stock in the AOC Restructuring and that, in order to make the transaction “costless” to us, that AOC reimburse us for all of our out-of-pocket expenses related to the transaction. In addition, Mr. Stoll proposed that (1) as a requirement to the consummation of the AOC Restructuring, the private letter ruling from the Internal Revenue Service anticipated to be received by AOC be satisfactory to us and (2) the shares of our common stock be issued pursuant to an exemption from registration under the Securities Act of 1933.
 
On November 30, 2006, Mr. Booth responded to our proposal and suggested that we pay 2,295,770 shares of our common stock in the AOC Restructuring and that AOC would reimburse our expenses, subject to a cap. In addition, Mr. Booth’s November 30 proposal stated that if we were unwilling to register the shares of our common stock issued to AOC, then the number of shares it was willing to receive as consideration was subject to change to take into account an appropriate discount for restricted securities.
 
On December 6, 2006, Mr. Schjerven, Ms. Carter and Mr. Stoll reviewed the status of the AOC discussions with the Audit Committee of the Board of Directors (which was comprised of Mr. Henry, Ms. Cooper, Mr. Major and Mr. Schmidt at that time) and Mr. Thompson. The Audit Committee

authorized management to proceed with negotiations with AOC within certain parameters. Following the Audit Committee meeting, Mr. Stoll contacted Mr. Booth and suggested a meeting to discuss the transaction.
 
On December 13, 2006, Mr. Stoll, David Dorsett, our Vice President, Tax, and representatives from Baker Botts L.L.P., counsel to our company, met with Mr. Booth and representatives from Thompson & Knight LLP, counsel to AOC, to discuss the AOC Restructuring. Mr. Stoll again stated that the disinterested members of our Board of Directors desired to share equally the benefits of the AOC Restructuring, and the parties discussed the benefits and costs of each party to the transaction. Mr. Booth and Mr. Stoll again met on January 12, 2007 and Mr. Booth proposed that we pay 2,270,534 shares of our common stock in the AOC Restructuring. As a result of such conversations, on January 25, 2007, Mr. Stoll proposed that we pay consideration of 2,239,589 shares of our common stock in the AOC Restructuring and that AOC reimburse us for all of our expenses related to such transaction up to a maximum of $250,000, regardless of whether the transaction is consummated. Mr. Stoll also proposed that the shares of our common stock would be issued in a transaction exempt from the registration requirements of the Securities Act of 1933. Mr. Booth later advised Mr. Stoll that the proposal had been accepted by AOC’s board of directors. On February 2, 2007, AOC provided us with a draft of the Reorganization Agreement and the terms of such agreement were negotiated by our representatives and representatives of AOC over the next several weeks.
 
On February 20, 2007, Mr. Stoll met with the Audit Committee of our Board of Directors (comprised of Mr. Schmidt, Ms. Cooper, Mr. Henry and Mr. Major) and updated them on the status of discussions with AOC. The Audit Committee approved the AOC Restructuring on the terms described above and resolved to recommend the AOC Restructuring to our Board of Directors. On February 26, 2007, our Board of Directors met with management and discussed and reviewed the terms of the AOC Restructuring (Steven R. Booth, Thomas W. Booth, John W. Norris, III and Jeffrey D. Storey, M.D. did not participate in the meeting because of their interest in the transaction as discussed below under ‘‘—Interests of Certain Persons in the Transaction”). The disinterested directors approved the AOC Restructuring on the terms described above, authorized management to negotiate and enter into the Reorganization Agreement and directed that the issuance of up to 2,239,589 shares of our common stock in exchange for the 2,695,770 shares of our common stock owned by AOC be submitted to our stockholders for approval. On March 16, 2007, the Reorganization Agreement was executed by our company and AOC.
 
Reasons for the Transaction
 
The disinterested directors of our Board of Directors believe that it is in the best interests of our company and our stockholders to approve the issuance of up to 2,239,589 shares of our common stock in exchange for the 2,695,770 shares of our common stock owned by AOC. The disinterested directors considered a number of factors, including those set forth below, in reaching its decision to approve the transaction and to recommend its approval to our stockholders:
 
  •    In September 2005, we announced that our Board of Directors had authorized a stock repurchase program to repurchase up to ten million shares of our common stock. As of December 31, 2006, we had repurchased 6,357,041 shares of our common stock under this program. The disinterested directors believe that the AOC Restructuring represents an additional way to increase stockholder value by further reducing the number of outstanding shares of our common stock at minimal cost to us.
 
  •    The disinterested directors believe that it is appropriate for us to share equally with AOC and its shareholders the economic benefits of the AOC Restructuring. Based on their analysis, the disinterested directors believe that 2,239,589 shares of our common stock appropriately shares such benefits.
 
The Reorganization Agreement
 
On March 16, 2007, we entered into the Reorganization Agreement with AOC, which provides that we will issue 2,239,589 shares of our common stock (subject to reduction if cash is delivered in lieu of fractional shares) in exchange for 2,695,770 shares of our common stock owned by AOC. AOC’s assets consist solely of

Table of Contents

cash and the 2,695,770 shares of our common stock. As soon as practicable following the exchange of our common stock, AOC will distribute the newly acquired shares of our common stock pro-rata to its shareholders. The liquidation and distribution will be structured so that the issuance of shares of our common stock will be exempt from registration under the Securities Act of 1933.
 
Pursuant to the Reorganization Agreement, each of our company and AOC has made various customary representations, warranties and covenants. Among other things, AOC has agreed to (1) reimburse us for all out-of-pocket expenses reasonably incurred by us up to $250,000, (2) take all commercially reasonable actions to hold a special meeting of AOC shareholders for approval of the transfer to us of the 2,695,770 shares of our common stock owned by AOC and the subsequent dissolution of AOC, and (3) recommend (subject to AOC’s board of directors’ fiduciary obligations to its shareholders) the approval of such transaction to the AOC shareholders. Among other things, we have agreed to (1) submit a proposal to our stockholders to approve the issuance of up to 2,239,589 shares of our common stock and to recommend (subject to our Board of Directors’ fiduciary obligations to our stockholders) the approval of such issuance, (2) prepare a private placement memorandum for the purpose of satisfying an exemption from registration of the issuance of up to 2,239,589 shares of our common stock and (3) submit an application to the New York Stock Exchange for the listing of the shares to be issued by us under the Reorganization Agreement. Our company and AOC have both agreed to treat the reorganization as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code and to file all tax returns consistently with such treatment.
 
Consummation of the transaction is subject to the satisfaction of certain conditions, including (1) receipt of a private letter ruling from the Internal Revenue Service that the transaction would qualify as a tax-free reorganization, (2) approval for listing on the New York Stock Exchange of the shares of our common stock to be issued in the AOC Restructuring, (3) approval by the holders of at least two-thirds of the outstanding AOC stock entitled to vote thereon, (4) approval by a majority of the votes cast by our stockholders (provided that the total votes cast in respect of the proposal represent more than 50% of all of our outstanding common stock entitled to vote thereon) and (5) execution of a registration rights agreement that would provide certain piggy back registration rights to the AOC shareholders.
 
The Reorganization Agreement may be terminated and the transaction abandoned at any time prior to closing (a) by the mutual written consent of AOC and our company, (b) by AOC following any breach by us of any of our representations and warranties or covenants that is not cured within five days, (d) by us following any breach by AOC of any of its representations and warranties or covenants that is not cured within five days, (e) by either party if either the AOC shareholders or our stockholders do not approve the transaction or (f) by either party if the transaction has not been consummated by September 30, 2007.
 
Interests of Certain Persons in the Transaction
 
In considering the Board’s recommendation to approve the issuance of up to 2,239,589 shares of our common stock pursuant to the Reorganization Agreement, you should be aware that certain of our directors have certain interests with respect to the AOC Restructuring that are different from, or in addition to, the interests of our public stockholders. Our Board was aware of these interests and considered them, among other matters, in approving the issuance of shares of our common stock pursuant to the Reorganization Agreement and in recommending that our stockholders approve the same. Based on the closing price of our common stock on the New York Stock Exchange on March 6, 2007, the 2,239,589 shares of our common stock to be issued pursuant to the Reorganization Agreement are valued at approximately $78,027,281.

There are no special benefits provided for any of the Related Persons under the Reorganization Agreement. Each Related Person’s participation in the AOC Restructuring arises out of his or her ownership of common stock of AOC and will be on the same basis as all other shareholders of AOC.
 
Reasons for Seeking Stockholder Approval
 
We are seeking stockholder approval of the issuance of shares to AOC pursuant to the Reorganization Agreement as required by paragraph 312.03(b) of the New York Stock Exchange Listed Company Manual (the “NYSE Manual”) because the issuance would result in the issuance of shares of common stock greater than one percent of our outstanding shares of common stock to AOC, an entity in which certain of our directors have a direct interest.
 
Pursuant to Section 312.03 of the NYSE Manual, an affirmative vote of the majority of the votes cast (provided that the total votes cast in respect of the proposal represent more than 50% of all of our outstanding common stock entitled to vote thereon) is required for approval of this proposal. As of February 1, 2007, Thomas W. Booth, Stephen R. Booth, John W. Norris, III and Jeffrey D. Storey, M.D., each a member of our

Board of Directors, collectively owned approximately 9% of our outstanding shares of common stock. Each of them has indicated that they currently intend to vote their shares of common stock in favor of the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE ISSUANCE OF SHARES OF COMMON STOCK PURSUANT TO THE REORGANIZATION AGREEMENT.
 
CORPORATE GOVERNANCE
 
Director Independence
 
Our Corporate Governance Guidelines require a majority of our directors to be “independent.” Pursuant to New York Stock Exchange listing standards, our Board of Directors has adopted a formal definition of “independent” for the purpose of determining whether a particular director or nominee meets the independence standards of our company and the New York Stock Exchange. In accordance with this definition, a director must be determined to have no personal, professional, familial or other relationship with our company other than as a director. The definition specifies the criteria by which the independence of our directors will be determined, including strict guidelines for directors and their immediate families with respect to past employment or affiliation with our company or our independent registered public accountants. The definition also prohibits directors from receiving any compensation from our company other than in his or her capacity as a director and from participating in any interlocking directorship where an executive officer of our company serves on the compensation committee of another company that concurrently employs the director. The full text of our definition of an independent director can be found on our website at www.lennoxinternational.com by following the links “About Us—Corporate Governance—Definition of Independent Director.”
 
Applying these standards and the independence standards of the New York Stock Exchange, the Board has determined that the following directors are independent: Linda G. Alvarado, James J. Byrne, Janet K. Cooper, C. L. (Jerry) Henry, John E. Major, Paul W. Schmidt, Terry D. Stinson and Richard L. Thompson.
 
A majority of our Board of Directors is independent, which helps ensure good corporate governance and strong internal controls. We believe we are in compliance with the corporate governance requirements of the New York Stock Exchange, the Securities and Exchange Commission and the Sarbanes-Oxley Act of 2002.
 
Board of Directors and Board Committees
 
The Board of Directors met eight times in 2006. All directors attended in excess of 75% of the total number of meetings of the Board and committees of the Board on which they served, except David V. Brown who attended 50% of the total number of meetings of the Board and committees of the Board on which he served prior to his retirement on April 20, 2006. The Board of Directors does not currently have a policy with regard to attendance of Board members at the Annual Meeting of Stockholders. Four directors attended our 2006 Annual Meeting of Stockholders.

The standing committees of the Board are as follows: Audit, Board Governance, Compensation and Human Resources, Acquisition, Pension and Risk Management and Public Policy. The Board has adopted charters for each of these committees which are available on our website at www.lennoxinternational.com by following the links “About Us—Corporate Governance—Committee Charters.” Stockholders may also receive a free copy of these documents by sending a written request to 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Investor Relations, or calling (972) 497-5000.
 
Audit Committee.  The Audit Committee, currently composed of Mr. Schmidt, Chairperson, Ms. Cooper, Mr. Henry and Mr. Major, met 15 times in 2006. The Audit Committee assists the Board in fulfilling its oversight responsibilities relating to the integrity of our financial statements and related systems of internal control, our compliance with legal and regulatory requirements, the independent registered public accounting firm’s qualifications, independence and performance and the performance of our internal audit function. The Audit Committee also has the direct responsibility for the appointment, compensation, retention and oversight of our independent registered public accountants. Each Audit Committee member is independent as independence for audit committee members is defined by the New York Stock Exchange and satisfies the New York Stock Exchange’s financial literacy requirements. The Board of Directors has determined that Mr. Schmidt, Chairperson of the Audit Committee, is an audit committee financial expert as defined by the Securities and Exchange Commission.
 
Board Governance Committee.  The Board Governance Committee, currently composed of Mr. Stinson, Chairperson, Mr. Henry and Mr. Schmidt, met five times in 2006. Each member of the Board Governance Committee is independent as independence for nominating committee members is defined by the New York Stock Exchange. The Board Governance Committee assists the Board by identifying individuals qualified to become Board members, developing and periodically reviewing the criteria for Board membership, making recommendations to the Board regarding the appropriate size of the Board and appointment of members to the Board’s committees and developing and recommending to the Board the Corporate Governance Guidelines and codes of conduct applicable to our company.
 
Compensation and Human Resources Committee.  The Compensation and Human Resources Committee, currently composed of Mr. Byrne, Chairperson, Ms. Alvarado, Mr. Major and Mr. Stinson, met four times in 2006. Each member of the Compensation and Human Resources Committee is independent as independence for compensation committee members is defined by the New York Stock Exchange. The Compensation and Human Resources Committee assists the Board in the discharge of its responsibilities relating to our compensation and benefits programs, oversight of our incentive plans, compensation of our directors, executive officers and other key employees and the development of executive succession and development plans.
 
The Compensation and Human Resources Committee approves all decisions relating to the compensation of our executive officers. In accordance with its charter, the committee reports to the full Board of Directors on a regular basis and seeks Board approval for certain actions. The committee forms and delegates authority to subcommittees when appropriate. For example, in 2006, the committee formed a subcommittee to assist in identifying candidates to succeed Mr. Schjerven as Chief Executive Officer of our company upon his retirement. Our Chief Executive Officer and, in some cases, other executive officers, make recommendations to the Compensation and Human Resources Committee with respect to various elements of executive and non-employee director compensation. In addition, our Chief Administrative Officer, who acts as management’s liaison to the committee, and our human resources department support the committee in the execution of its duties. Pursuant to its charter, the committee is authorized to obtain advice and assistance from internal or external legal, accounting or other advisors and to retain third-party compensation consultants. To that end, the committee has engaged Mercer Human Resource Consulting LLC as its executive compensation consultant to provide objective analysis, advice and recommendations in connection with the committee’s decision-making process. See “Executive Compensation—Compensation Discussion and Analysis” for further information regarding executive compensation decisions.
 
Acquisition Committee.  The Acquisition Committee, currently composed of Mr. Major, Chairperson, Mr. T. Booth, Mr. Byrne and Mr. Stinson, met five times in 2006. The Acquisition Committee is responsible

for evaluating and making recommendations to the Board of Directors regarding potential acquisitions and divestitures.
 
Pension and Risk Management Committee.  The Pension and Risk Management Committee, currently composed of Mr. S. Booth, Chairperson, Mr. T. Booth, Ms. Cooper, Mr. Norris, Mr. Schmidt and Dr. Storey met three times in 2006.

Public Policy Committee.  The Public Policy Committee, currently composed of Mr. Norris, Chairperson, Ms. Alvarado, Mr. S. Booth, Mr. Byrne and Dr. Storey, met once in 2006. The Public Policy Committee is responsible for developing educational programs for new and continuing directors and overseeing our position on corporate social responsibilities and public issues of significance that affect our stockholders.
 
Director Nominee Criteria and Nomination Process
 
The Board of Directors is responsible for approving candidates for Board membership. The Board has delegated the screening and recruitment process to the Board Governance Committee. In this capacity, the Board Governance Committee develops and periodically reviews the criteria for Board membership, identifies new director candidates and makes recommendations to the Board regarding the appropriate size of the Board and appointment of members to the Board’s committees. Qualifications required of individuals for consideration for Board membership will vary according to the particular areas of expertise being sought as a compliment to the existing Board composition at the time of any vacancy. Appropriate criteria for Board membership include:
 
  •    integrity, interpersonal skills and effectiveness, accountability and high performance standards;
 
  •    high levels of leadership experience in business, substantial knowledge of issues faced by publicly traded companies, experience in positions demonstrating expertise, including on other boards of directors, financial acumen, industry knowledge, diversity of view points, experience in international markets and strategic planning;
 
  •    expertise under the rules and regulations of the New York Stock Exchange and the Securities and Exchange Commission;
 
  •    ability and willingness to represent the stockholders’ long and short-term interests, awareness of our responsibilities to our customers, employees, suppliers, regulatory bodies and the communities in which we operate and willingness to advance his or her opinions while supporting the majority Board decision assuming questions of ethics or propriety are not involved;
 
  •    ability to understand and distinguish between the roles of governance and management; and
 
  •    availability and commitment.
 
The Board Governance Committee typically retains a third-party search firm to assist in identifying and evaluating potential new director candidates.
 
When a vacancy occurs on the Board, the Board Governance Committee recommends to the Board a nominee to fill the vacancy. The Board Governance Committee also evaluates and recommends to the Board nominees for election to our Board of Directors at our Annual Meeting of Stockholders.
 
Stockholder Nominations for Director
 
The Board Governance Committee considers nominees for election to the Board of Directors recommended by stockholders. A stockholder wishing to nominate a candidate for election to the Board at a meeting of the stockholders is required to give written notice to our Corporate Secretary of his or her intention to make a nomination. We must receive the notice of nomination at least 60 days but no more than 90 days prior to the


15


Table of Contents

Annual Meeting of Stockholders, or if we give less than 70 days notice of the Annual Meeting of Stockholders date, the notice of nomination must be received within 10 days following the date on which notice of the date of the Annual Meeting of Stockholders was mailed or such public disclosure was made to our stockholders. In the case of a special meeting of stockholders for the election of directors, we must receive the notice of nomination within 10 days following the date on which notice of such meeting is first given to stockholders. Pursuant to our Bylaws, the notice of nomination is required to contain certain information about both the nominee and the stockholder making the nomination, including information sufficient to allow the Board Governance Committee to determine if the candidate meets our criteria for Board membership. The Board Governance Committee may require that the proposed nominee furnish additional information in order to determine that person’s eligibility to serve as a director. A nomination that does not comply with the above procedure will be disregarded. Stockholder nominees whose nominations comply with the foregoing procedure and who meet the criteria described above under the heading “Director Nominee Criteria and Nomination Process” and in our Corporate Governance Guidelines, will be evaluated by the Board Governance Committee in the same manner as the Board Governance Committee’s nominees.

Excludes approximately 111,463 shares of common stock to be issued upon exercise of outstanding stock options originally granted under five equity compensation plans adopted by Service Experts Inc., one of our subsidiaries. We assumed such options, which have a weighted-average exercise price of $38.29, in connection with our acquisition of Service Experts in 2000. No additional options will be granted under Service Experts’ equity compensation plans.
 
(2) Excludes PSP awards and restricted stock awards because such awards have no exercise price.
 
(3) Includes 6,735,412 shares of common stock available for issuance under the 1998 Plan; 331,113 shares of common stock available for issuance under the Non-Employee Directors’ Compensation and Deferral Plan and 59,502 shares of common stock reserved for issuance under the Employee Stock Purchase Plan, which is no longer active.
 
CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
 
Thomas W. Booth, Stephen R. Booth and John W. Norris, III, each a member of our Board of Directors, John W. Norris, Jr., our former Chairman of the Board, David V. Brown, a former director of our company and Lynn B. Storey, the mother of Jeffrey D. Storey, M.D., a director of our company, as well as other stockholders of our company who may be immediate family members of the foregoing persons, are, individually or through trust arrangements, members of AOC Land Investment, L.L.C. (“AOC Land”). AOC Land owned 70% of AOC Development II, L.L.C. (“AOC Development”), which owned substantially all of One Lake Park, L.L.C. (“One Lake Park”) prior to the dissolution of AOC Development and One Lake Park in the second half of 2006. Beginning in 1998, we leased part of an office building in Richardson, Texas owned by One Lake Park for use as our corporate headquarters. We terminated these leases in June 2006. Our lease payments for 2006, 2005 and 2004 totaled approximately $1.4 million, $2.9 million and $3.2 million, respectively. We believe that the terms of our leases with One Lake Park were, at the time entered into, comparable to terms that could have been obtained from unaffiliated third parties. Please refer to “Proposal 1: Election of Directors” and “Proposal 2: Approval of the Issuance of Shares of our Common Stock Pursuant to an Agreement and Plan of Reorganization with A.O.C. Corporation” for additional information regarding family relationships that exist among certain members of our Board of Directors and related party transactions.
 
In December 2006, our Board of Directors adopted the Lennox International Inc. Related Party Transactions Policy, pursuant to which all related party transactions must be approved. Subject to limited exceptions, the written policy generally covers all transactions between our company and any director or executive officer, including their immediate family members and affiliates, as well as stockholders holding more than five percent of our common stock. Our Audit Committee is responsible for approving all related party transactions which must be on terms that are fair to our company and comparable to those that could be obtained in arm’s length dealings with an unrelated third party. In the event management recommends any related party transaction in between regularly scheduled Audit Committee meetings, such transactions may be presented to the Chairman of the Audit Committee for approval, subject to ratification by the Audit Committee at the next regularly scheduled meeting. In the event a related party transaction involves one or more members of the Audit Committee, the transaction must be approved by an ad hoc committee appointed by the Board and comprised entirely of independent and disinterested directors. Prior to adopting a formal written policy, we did not enter into any transactions in which our directors, executive officers or principal stockholders and their affiliates have a material interest unless such transactions were approved by a majority of the disinterested members of our Board of Directors and were on terms that are no less favorable to us than those that we could obtain from unaffiliated third parties.
 
Compensation Committee Interlocks and Insider Participation
 
During 2006, no member of the Compensation and Human Resources Committee was an officer or employee of our company or any of our subsidiaries. In addition, none of our executive officers served on the board of directors or on the compensation committee of any other entity, for which any executive officers of such other entity served either on our Board or on our Compensation and Human Resources Committee.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers and persons who beneficially own more than 10% of our common stock to file with the Securities and Exchange Commission and the New York Stock Exchange initial reports of ownership and reports of changes in their ownership of our common stock. Securities and Exchange Commission regulations require our directors, executive officers and greater than 10% stockholders to furnish us with copies of these reports. Based solely upon a review of such reports and related information furnished to us, we believe that, during the 2006 fiscal year, each person who served as a director or executive officer of our company or held more than 10% of our common stock complied with the Section 16(a) filing requirements except as follows:
 
  •    Robert J. McDonough inadvertently filed one Form 4, reporting three transactions involving open market sales, three days late;
 
  •    Each of Robert E. Schjerven, Harry A. Ashenhurst, Ph.D., Thomas W. Booth, Scott J. Boxer, Linda A. Goodspeed, David Inman, and Robert J. McDonough inadvertently failed to report one transaction involving the surrender of common stock to satisfy his or her tax withholding obligation in connection with the vesting of a PSP award. Upon discovery of the oversight, each of the foregoing individuals promptly filed an amended Form 4 reporting the transaction;
 
  •    Each of Harry J. Bizios, David W. Moon and Douglas L. Young inadvertently failed to account for the surrender of common stock to satisfy his tax withholding obligation in connection with the vesting of a PSP award when reporting the amount of securities beneficially owned on Form 3. Upon discovery of the oversight, each of the foregoing individuals promptly filed an amended Form 3 reporting the correct amount of securities beneficially owned; and
 
  •    Jeffrey D. Storey, M.D. inadvertently failed to account for certain shares when reporting the amount of securities beneficially owned on Form 3. Upon discovery of the oversight, Dr. Storey promptly filed an amended Form 3 reporting the correct amount of securities beneficially owned.

AUDIT COMMITTEE REPORT
 
Audit Committee Charter.  The Audit Committee of Lennox International Inc. acts pursuant to its written charter adopted by the Board of Directors. The role of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing the Company’s financial reporting process, the system of internal control, the audit process and the Company’s process for monitoring compliance with laws and regulations and corporate policies. The Audit Committee maintains effective working relationships with the Board of Directors, management, the Company’s internal auditors and the Company’s independent registered public accounting firm (“Independent Accountants”). As set forth in the Audit Committee Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company’s financial statements and disclosures are complete and accurate and in accordance with generally accepted accounting principles and applicable rules and regulations of the Securities and Exchange Commission and the New York Stock Exchange. The Independent Accountants are responsible for auditing the Company’s financial statements and expressing an opinion as to their conformity with generally accepted accounting principles.
 
Auditor Independence.  The Audit Committee has reviewed and discussed the quarterly and audited financial statements, including the quality of accounting principles, with management and the Independent Accountants. The Audit Committee has also discussed with the Independent Accountants the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as currently in effect. Finally, the Audit Committee has received the written disclosures and the letter from the Independent Accountants required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, as currently in effect, and has discussed with the Independent Accountants the Independent Accountants’ independence and considered whether the provision of non-audit services by the Independent Accountants to the Company is compatible with maintaining the accountants’ independence.
 
Members of the Audit Committee rely, without independent verification, on the information provided to them and on the representations made by management and the Independent Accountants. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions referred to above do not assure that the audits of the Company’s financial statements have been carried out in accordance with generally accepted auditing standards, that the financial statements are presented in accordance with generally accepted accounting principles or that the Company’s Independent Accountants are in fact “independent.”
 
Audit Committee Recommendation.  Based upon the reviews and discussions described above, and subject to the limitations on the role and responsibilities of the Audit Committee referred to in this report and in the Audit Committee Charter, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.
 
Submitted by the Audit Committee of the Board of Directors:
 
     
         Paul W. Schmidt (Chairperson)   Janet K. Cooper

INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS
 
The Audit Committee of the Board of Directors has selected KPMG LLP (“KPMG”) to continue as our independent registered public accounting firm for the fiscal year ending December 31, 2007. A representative of KPMG will be present at the 2007 Annual Meeting of Stockholders and will be available to respond to appropriate questions. The representative will also have an opportunity to make a statement at the meeting if he or she desires to do so.

TOTAL
  $ 6,513     $ 5,946  
                 
 
 
(1) The amounts shown for 2005 may differ from the amounts shown in last year’s Proxy Statement due to the finalization of billings for services rendered in 2005.
 
(2) Represents fees billed by KPMG for the audit of our annual financial statements included in our Annual Reports on Form 10-K and review of financial statements included in our Quarterly Reports on Form 10-Q; the audit of our internal control over financial reporting; and for services that are normally provided by KPMG in connection with statutory and regulatory filings or engagements.
 
(3) Represents fees billed by KPMG for assurance and related services reasonably related to the performance of the audit or review of our financial statements and internal control over financial reporting. Such services consisted primarily of audits of our employee benefit plans.
 
(4) Represents fees billed by KPMG for tax compliance, including review of tax returns, tax advice and tax planning.
 
(5) We generally do not engage KPMG for “other” services.
 
Audit Committee Approval of Audit and Non-Audit Services
 
The Audit Committee pre-approves all audit services provided by KPMG. In addition, all non-audit services provided by KPMG are pre-approved in accordance with our policy entitled “Use of External Audit Firm for Non-Attest Services.” The policy identifies services that are specifically prohibited by Securities and Exchange Commission rules and states that these services may not be performed by our external auditors. For permissible non-audit services, the Audit Committee has delegated pre-approval authority to the Audit Committee Chairperson. In addition, the Audit Committee has approved annual maximum amounts for tax advisory and tax return services. No engagements are commenced until the Audit Committee Chairperson’s approval has been received. All approved services are reported to the full Audit Committee at each quarterly meeting.
 
In accordance with the foregoing, all services provided by KPMG in 2006 were pre-approved by the Audit Committee.

OTHER INFORMATION
 
Proxy Solicitation
 
We will pay for the cost of this proxy solicitation. In addition to solicitation by mail, our directors, officers and employees may solicit proxies from stockholders by telephone, facsimile, email or in person. They will not be paid for soliciting proxies but may be reimbursed for out-of-pocket expenses related to the proxy solicitation. We will also make arrangements with brokerage houses and other custodians, nominees and fiduciaries to send the proxy materials to beneficial owners of our common stock. Upon request, we will reimburse the brokerage houses and custodians for their reasonable expenses in so doing.
 
Multiple Stockholders Sharing the Same Address
 
We have adopted a procedure approved by the Securities and Exchange Commission called “householding.” Under this procedure, stockholders who have the same address and last name will receive only one copy of our Annual Report to Stockholders, Notice of Annual Meeting of Stockholders, Proxy Statement and Annual Report on Form 10-K, unless one or more of these stockholders notifies us that they wish to continue receiving individual copies. This procedure helps reduce our printing costs and postage fees.
 
Stockholders who participate in householding will continue to receive separate Proxy Cards. Also, householding will not in any way affect dividend check mailings.
 
If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the Annual Report to Stockholders, Notice of Annual Meeting of Stockholders, Proxy Statement and Annual Report on Form 10-K, or if you hold stock in more than one account, and in either case you wish to receive only a single copy of each of these documents for your household, please contact our Investor Relations department by telephone at (972) 497-5000 or in writing at 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Investor Relations.
 
If you participate in householding and wish to receive a separate copy of our Annual Report to Stockholders, Notice of Annual Meeting of Stockholders, Proxy Statement and Annual Report on Form 10-K, please contact our Investor Relations department as indicated above.
 
Stockholder Proposals for the 2008 Annual Meeting of Stockholders
 
Proposals for Inclusion in the Proxy Statement.  If you wish to submit a proposal for possible inclusion in our 2008 proxy materials, we must receive your notice, in accordance with the rules of the Securities and Exchange Commission, on or before December 18, 2007. The proposal should be sent in writing to 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Corporate Secretary.
 
Proposals to be Offered at an Annual Meeting.  If you wish to introduce a proposal at the 2008 Annual Meeting of Stockholders but do not intend for your proposal to be considered for inclusion in our 2008 proxy materials, our Bylaws, as permitted by the rules of the Securities and Exchange Commission, require that you follow certain procedures. More specifically, you must give written notice to our Corporate Secretary of your intention to introduce a proposal. We must receive such notice at least 60 days but no more than 90 days prior to the Annual Meeting of Stockholders, or if we give less than 70 days notice of the Annual Meeting of Stockholders date, the notice must be received within 10 days following the date on which notice of the date of the Annual Meeting of Stockholders was mailed or such public disclosure was made to our stockholders. In the case of a special meeting of stockholders, we must receive notice of your intention to introduce a proposal within 10 days following the date on which notice of such meeting is first given to stockholders. Depending on the nature of your proposal, additional information may be required (see “Corporate Governance—Stockholder Nominations for Director”).

In consideration therefor, at the Closing and subject to the terms and conditions set forth in this Agreement, LII shall deliver to AOC 2,239,589 shares (subject to reduction pursuant to section 2.6(i)) of LII Common Stock (the “New LII Shares”) issued in the names of the AOC Shareholders in such amounts as set forth in the Consideration Certificate. The New LII Shares will contain the following or similar legend:
 
“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE APPLICABLE SECURITIES LAWS OF ANY STATE, AND MAY NOT BE OFFERED FOR SALE, SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO (A) AN EFFECTIVE REGISTRATION STATEMENT IN COMPLIANCE WITH THE REQUIREMENTS OF ALL SUCH LAWS OR (B) AN EXEMPTION FROM SUCH REGISTRATION AND AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED BY SUCH LAWS.”
 
(ii) At least two business days prior to the Closing, AOC shall deliver to LII a certificate executed on behalf of AOC by its Chairman or President setting forth (a) the names and addresses of the AOC shareholders of record on the Closing Date (the “AOC Shareholders”); (b) the number of shares of AOC Common Stock owned by the AOC Shareholders on the Closing Date; (c) the number of New LII Shares to be issued to each AOC Shareholder in accordance with his or her Pro Rata Share and the exact name that should appear on each stock certificate representing that number of whole New LII Shares to be issued to each AOC Shareholder pursuant to this Section 2.1 and Section 2.2; (d) the decision by AOC either to distribute cash in lieu of fractional shares or to round the New LII Shares upward or downward pursuant to Section 2.6; and (e) the respective cash amounts in lieu of fractional shares payable to each AOC Shareholder or the results of such rounding pursuant to Section 2.6 (the “Consideration Certificate”).
 
(iii) LII shall not assume or become liable for any debts, liabilities or obligations of AOC, whether absolute or contingent, known or unknown, accrued or unaccrued or otherwise (collectively, the “Liabilities”).
 
2.2  AOC Liquidating Distribution; Dissolution.  Prior to the Closing, AOC shall distribute the Cash Dividend to its shareholders pro rata. As soon as practicable after the Closing Date but not later than 30 days thereafter, AOC shall distribute to the AOC Shareholders in accordance with their respective Pro Rata Share and in liquidation of AOC (i) the stock certificates representing the whole New LII Shares, (ii) the cash (if any) paid by LII in lieu of fractional shares pursuant to Section 2.6, and (iii) the assets (if any) of AOC remaining after the satisfaction of all of its Liabilities. Such distribution in liquidation of AOC shall be structured so that the issuance of the New LII Shares to the AOC Shareholders is exempt from registration under the Securities Act pursuant to Rule 506 of Regulation D promulgated thereunder. AOC agrees to take all steps necessary to dissolve AOC in a reasonable amount of time after the liquidating distribution and in no event later than 180 days following the Closing Date.

written objection to the Reorganization in accordance with Article 5.12 of the TBCA shall be entitled to payment of the fair value of such shares in accordance with the provisions of Articles 5.11 through 5.13, inclusive, of the TBCA; provided that if such AOC Shareholder fails to perfect or effectively withdraws or loses his or her right to payment of the fair value of his shares under the TBCA, such shares shall be treated as if they had been voted in favor of the Reorganization. AOC shall give LII prompt notice of any objections or demands received by AOC from any shareholder exercising his right to dissent, and, prior to the Closing Date, LII shall have the right to participate in all negotiations and proceedings with respect thereto. Prior to the Closing Date, AOC shall not, except with the prior written consent of LII, make any payment with respect to, or settle or offer to settle, any such objections or demands.

AOC shall provide LII with notice of any registration of transfers of AOC Common Stock that occur between the date of this Agreement and the closing of its stock transfer books.

(ii) If AOC determines to round the fractional shares, (a) each fractional share of LII Common Stock that any AOC Shareholder would otherwise receive but for this Section 2.6, shall be rounded upward or downward to the next whole number of New LII Shares, as determined by AOC in its sole discretion, and the aggregate number of shares to be received by such AOC Shareholder pursuant to this Agreement shall be adjusted accordingly as determined by AOC in its sole discretion and (b) the aggregate number of New LII Shares to be delivered to AOC pursuant to Section 2.1 shall not change.
 
(iii) The (i) decision by AOC either to (A) distribute cash in lieu of fractional shares or (B) round the New LII Shares upward or downward, and (ii) respective cash amounts payable to each AOC Shareholder or the results of such rounding, as applicable, shall be set forth in the Consideration Certificate.
