PROPOSAL 2: AMENDMENT TO THE EMPLOYEE STOCK PURCHASE PLAN Reasons for the Amendment The Board of Directors believes that the availability of an opportunity to purchase shares under the Employee Stock Purchase Plan, as amended (the "Purchase Plan"), at a discount from market price is important to attracting and retaining qualified officers and employees essential to the success of Lennox, and that stock ownership is important to providing such persons with incentive to perform in the best interest of Lennox. Accordingly, in 1998, the Board of Directors adopted the Purchase Plan and later amended the Purchase Plan in 1999, subject to stockholder approval, which approval was obtained in 1999. An aggregate of 825,000 shares of Lennox common stock was originally authorized for purchase and issuance pursuant to the Purchase Plan. As of December 31, 2000 approximately 15,715 shares remained available for future issuance under the Purchase Plan. Therefore, in December 2000, subject to stockholder approval, the Board of Directors increased the number of shares authorized for issuance under the Purchase Plan by 1,750,000 shares to an aggregate of 2,575,000 shares. The stockholders are now being requested to approve the increase in the Purchase Plan reserve at the Annual Meeting. Description of the Purchase Plan The following summary of the principal features of the Purchase Plan is qualified in its entirety by the specific language of the Purchase Plan, a copy of which is available to any stockholder upon request to the Secretary of Lennox, 2140 Lake Park Blvd., Richardson, Texas 75080. General. The Purchase Plan became effective in July 1999. The purpose of the Purchase Plan is to encourage and assist all eligible employees of Lennox and its subsidiaries ("Employees") to acquire an equity interest in Lennox through the purchase of shares of common stock. The Purchase Plan enables employees to purchase common stock at a discount to market price through regular payroll deductions. The Purchase Plan is intended to qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). Shares Subject to Plan. Currently, a maximum of 825,000 of Lennox' authorized but unissued or reacquired shares of common stock may be issued under the Purchase Plan, subject to appropriate adjustment in the event of a stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification or similar change in Lennox' capital structure or in the event of any merger, sale of assets or other reorganization of Lennox. In December 2000, the Board of Directors, subject to stockholder approval, amended the Purchase Plan to increase its share reserve by 1,750,000 shares to an aggregate of 2,575,000 shares. Administration and Eligibility. The Purchase Plan is administered and interpreted by the Compensation Committee of the Board of Directors. Any Employee of Lennox or any participating subsidiary is eligible to participate in the Purchase Plan; provided, however, that Employees who are customarily employed less than 20 hours per week or less than five months per year are not eligible. Furthermore, no Employee is eligible to participate in the Purchase Plan who would own, after purchasing common stock subject to options, shares of capital stock representing 5% or more of the total combined voting power of Lennox or any subsidiary. Method of Payment. Payment for shares is to be made as of the applicable "Purchase Date" through payroll deductions on an after-tax basis (with no right of prepayment) over the Purchase Plan's designated purchase period (the "Purchase Period"), with the first such deduction commencing as soon as administratively practicable following the enrollment date and after the Employee has satisfied the enrollment requirements. Each Purchase Period under the Purchase Plan is for a period of six months beginning on each January 1 and July 1 and ending on the following June 30 or December 31 or such other period as the Compensation Committee may prescribe. Each participating Employee ("Participant") may elect to make contributions each pay period in amounts not less than one percent of compensation and not more than 10 percent of compensation (or such other percentages as the Compensation Committee may establish from time to time before an enrollment date for all 7

purchases to occur during the relevant Purchase Period). For all purposes of the Purchase Plan, compensation shall mean salary or wages plus bonuses, overtime and any commissions paid. In establishing other percentages of permitted contributions, the Compensation Committee may take into account the "Maximum Share Limitation", as defined below. The rate of contribution shall be designated by the Participant at the time of enrollment. A Participant may elect to increase or decrease the rate of contribution, effective as of the first day of any Purchase Period, or suspend payroll deductions at any time during the Purchase Period, in accordance with the terms and conditions of the Purchase Plan. Except in the case of a Participant's suspension of payroll deductions or termination of employment, and subject in all cases to the Maximum Share Limitation, the amount in a Participant's account at the end of the Purchase Period will be applied to the purchase of common stock. Purchase of Shares. The right to purchase shares of common stock granted by Lennox under the Purchase Plan is for the term of a Purchase Period. The fair market value of the common stock ("Fair Market Value") to be purchased during such Purchase Period will be determined first as the closing composite sales price per share of the common stock in the New York Stock Exchange Composite Transactions Quotations on the first trading days of the calendar months of January and July, or such other trading dates designated by the Compensation Committee (the "Grant Date"). The Fair Market Value of the common stock will again be determined in the same manner on the last trading days of the calendar months of June and December, or such other trading dates designated by the Compensation Committee (the "Purchase Date"), in accordance with the Purchase Plan. The right to purchase shares (taken together with all other such rights then outstanding under this Plan and under any other similar stock purchase plans of Lennox) will in no event give the Participant the right to purchase a number of shares during a calendar year in excess of the number of shares of common stock derived by dividing $25,000 by the Fair Market Value of the common stock (the "Maximum Share Limitation") on the applicable Grant Date. The right to purchase shares will in all respects be subject to the terms and conditions of the Purchase Plan, as interpreted by the Compensation Committee from time to time. As of the Purchase Date, the Compensation Committee applies the funds then credited to each Participant's account to the purchase of shares of common stock. The cost to the Participant for the shares purchased during a Purchase Period shall be the lower of: (i) 85 percent (85%) of the Fair Market Value of common stock on the Grant Date; or (ii) 85 percent (85%) of the Fair Market Value of common stock on the Purchase Date. In the case of any Participant whose compensation is not paid in U.S. dollars, amounts accumulated in such Participants' account are converted into U.S. dollars on each Purchase Date by reference to the New York foreign exchange selling rates reported in The Wall Street Journal for the last business day immediately preceding such Purchase Date. If, as of any Purchase Date the shares authorized for purchase under the Purchase Plan are exceeded, enrollments are reduced proportionately to eliminate the excess. Any funds that cannot be applied to the purchase of shares due to excess enrollment are refunded as soon as administratively practicable. The Compensation Committee in its discretion may also provide that excess enrollments may be carried over to the next Purchase Period under the Purchase Plan or any successor plan according to the regulations set forth under Section 423 of the Code. Withdrawal of Shares and Sale of Shares. A Participant may elect to withdraw at any time (without withdrawing from participation in the Purchase Plan) shares that have been held in his account for at least 18 months by giving notice to the person designated by the Compensation Committee in the appropriate manner. Notwithstanding anything in the Purchase Plan to the contrary, a Participant may sell shares that are held in his account, including shares that have been held in his account for less than 18 months, by giving notice to such designated person. Any sale will be deemed to occur on the last business day of the month in which the Participant provides such notice or at such other time as the Compensation Committee shall establish. The proceeds of any such sale less any associated commissions and required withholding for taxes, are paid to the Participant as soon as practicable after the sale. 8

Termination of Participation. The right to participate in the Purchase Plan terminates immediately when a Participant ceases to be employed by Lennox for any reason whatsoever (other than the death of the Participant, but including retirement and disability) or the Participant otherwise becomes ineligible. Participation terminates immediately after the Purchase Date if the Participant is not re-enrolled in the Purchase Plan for the next Purchase Period or if the Participant has suspended payroll deductions during any Purchase Period and has not re-enrolled in the Purchase Plan for the next Purchase Period. Modification or Termination. The Board of Directors may amend or terminate the Purchase Plan at any time insofar as permitted by law. No amendment shall be effective unless within one year of the time it is adopted by the Board of Directors it is approved by the holders of a majority of outstanding shares of common stock, if and to the extent such amendment is required to be approved by stockholders in order to cause the rights granted under the Purchase Plan to purchase shares of common stock to meet the requirements of Section 423 of the Code (or any successor provision). The Purchase Plan shall terminate after all common stock authorized for issuance under the Purchase Plan has been purchased, unless terminated earlier by the Board of Directors or unless additional common stock is authorized for issuance under the Purchase Plan with the approval of Lennox' stockholders. In the event the Purchase Plan is terminated, the Compensation Committee may elect to terminate all outstanding rights to purchase shares under the Purchase Plan either immediately or upon completion of the purchase of shares on the next Purchase Date, unless the Compensation Committee has designated that the right to make all such purchases shall expire on some other designated date occurring prior to the next Purchase Date. If the rights to purchase shares under the Purchase Plan are terminated prior to expiration, all funds contributed to the Purchase Plan which have not been used to purchase shares shall be returned to the Participants as soon as administratively practicable. Summary of United States Federal Income Tax Consequences. The following summary is intended only as a general guide as to the United States federal income tax consequences under current law of participation in the Purchase Plan and does not attempt to describe all possible federal or other tax consequences of such participation or tax consequences based on particular circumstances. A Participant does not incur any federal income tax liability on the purchase of common stock under the Purchase Plan. Upon a subsequent sale of the common stock after the required holding period (two (2) years after the purchase right is granted and one (1) year after the purchase of the shares) or upon death, a Participant will realize ordinary income in an amount equal to the lesser of (a) the excess of the fair market value of the common stock at date of disposition or death over the amount paid for the common stock or (b) the excess of the fair market value of the common stock at the Grant Date over the amount paid for the common stock; the Participant will realize capital gain on any additional difference between the disposition price of the common stock and the amount paid for the common stock. Upon early disposition of any of the common stock (if the holding period requirements are not met), the Participant disposing of the common stock will have ordinary income in an amount equal to the difference between the amount paid for the common stock and the fair market value of the common stock at the date the common stock was purchased (and Lennox will have a corresponding deduction). Any remaining gain on such disposition will be taxable as a capital gain. Any loss on disposition would be a capital loss. Dividends paid under the Purchase Plan are taxable income to the Participant when such dividends are paid. Lennox intends that the Purchase Plan will constitute an "employee stock purchase plan" under the provisions of Section 423 of the Code. The Purchase Plan is not qualified under Section 401(a) of the Code. The Board Of Directors Recommends A Vote "For" The Amendment To The Employee Stock Purchase Plan. 9

The role of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing Lennox' financial reporting process, the system of internal control, the audit process, and Lennox' process for monitoring compliance with laws and regulations and Lennox' policies. In performing its role, the Audit Committee maintains effective working relationships with the Board of Directors, management, the internal auditors and the independent accountants. As set forth in the Charter, Lennox management is responsible for the preparation, presentation and integrity of Lennox' financial statements, Lennox' accounting and financial reporting principles and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent accountants are responsible for auditing Lennox' financial statements and expressing an opinion as to their conformity with generally accepted accounting principles. Auditor Independence. In the performance of its oversight function, 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 accountant's independence and considered the compatibility of non-audit services with the auditors' 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 Lennox' 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 Lennox' accountants are in fact "independent". Audit Committee Recommendation. Based upon the reports and discussions described in this report, and subject to the limitations on the role and responsibilities of the Audit Committee referred to above and in the Audit Committee Charter, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in Lennox' Annual Report on Form 10-K for the year ended December 31, 2000. Disclosure of Fees.

DIRECTORS COMPENSATION Directors who are employees of Lennox do not receive additional compensation for positions on the Board of Directors. In 2000, there were two employee board members: Messrs. John W. Norris, Jr., Chairman of the Board and Chief Executive Officer, and Thomas W. Booth, Vice President, Advanced Heat Transfer, Heatcraft Inc. The 2000 compensation package for all other directors included an annual retainer of $25,000 in cash and $10,000 in common stock for Board of Directors and committee service, an annual retainer of $4,000 in cash for serving as a committee chair and a fee of $1,000, or $500 in the event of a telephonic meeting, in cash for attending each meeting day of the Board of Directors or any committee of the Board. Board members may elect to receive the cash portion of their annual retainer in cash or shares of common stock. Directors may defer 25% or more of their annual cash retainer in an interest bearing account. All directors receive reimbursement for reasonable out-of- pocket expenses incurred in connection with attendance at meetings of the Board of Directors or a committee of the Board. In addition, each non-employee director may periodically, under the 1998 Incentive Plan of Lennox International Inc. (the "Plan"), administered by the Board of Directors, receive options to purchase shares of common stock at an exercise price equal to the fair market value of such shares at the date of grant. In 2000, each non-employee director was awarded 15,131 options to purchase stock. Under the Plan, options are non-qualified, and no such options awarded in any given year shall provide for the purchase of more than 16,500 shares of common stock. All options awarded to directors in 2000 have a term of seven years and vest and become exercisable in increments of one-third on each of the three succeeding anniversaries after the date of grant. If a director resigns, unvested options are forfeited unless a majority of the remaining board members decides otherwise. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION Executive Compensation Philosophy and Policy Executive compensation is administered by the Compensation Committee of the Lennox Board of Directors (the "Committee"), which is composed of the four outside board members listed below. This report defines the philosophy and describes the decisions made by the Committee during 2000 with respect to the executive officers. It is the Committee's goal to establish executive compensation programs which deliver total pay linked to overall business results and, therefore, attract, motivate and retain highly skilled executives whose performance and contributions result in increased stockholder value. To that end, Lennox maintains a pay-for-performance compensation philosophy to pay market-competitive base salaries, while also delivering variable pay which is directly linked to the achievement of company performance measurements and to the performance and contribution of the individual. In addition to the base salary program, Lennox' variable pay programs include both short- and long- term incentive compensation vehicles. In order to evaluate the competitiveness of the executive total compensation program, the Committee has periodically engaged nationally recognized human resources consulting firms to conduct market analyses of the company's executive pay programs and practices. The Committee emphasizes delivering market-competitive and flexible total compensation to support the company's business objectives. Lennox' executive pay is compared to a group of companies similar to Lennox, although not necessarily the same companies included in the peer group in the performance graph in this proxy statement. Base Salary Executive Officers Lennox' executive base salary program is designed to be competitive with the marketplace. In 2000, the Committee administered the officers' base salaries within an executive broad band salary range to provide flexibility to reward executive development, support succession planning and aid in executive recruiting. Market-competitive values from the consultant's market analysis were assigned to each specific position within the broad band. The analysis showed that overall base salaries for executive officers, including Mr. Norris, were somewhat 12

below market averages. For 2000, the Committee reviewed the base salary of each executive officer in relationship to the consultant's market data for the specific position, assessed the individual's performance relative to previously established objectives and also made subjective determinations regarding the individual's contributions before adjusting base salaries. After these adjustments, executive salaries were competitive in the market and commensurate with the experience and performance contributions of the executive officers. Chief Executive Officer In determining Mr. Norris' 2000 base salary, the Committee reviewed the results of the consultant's market analysis for the CEO position. For 2000, Mr. Norris' base salary was $800,004, an amount approximating the market value from the consultant's analysis. Positioning Mr. Norris' 2000 base salary near the market value reflects the Committee's support of Lennox' philosophy of paying its executives a market-competitive base salary and the Committee's assessment of Mr. Norris' performance during the prior year. Some of the significant achievements considered included: . Lennox continued the execution of its international growth strategy. . Major progress was made domestically in penetrating North American markets. . Supporting Lennox' domestic growth strategy, several successful U.S. acquisitions occurred, the largest of which was the expansion into the retail industry through the acquisition of HVAC dealers. . Mr. Norris and his team worked diligently to demonstrate improved results to Lennox' stockholders and to the investment community to reverse the disappointing market valuation evidenced by the decline of the stock price since the Lennox initial public offering. Short-Term Incentive Compensation Executive Officers Based on the consultant's market analysis, the Committee administered short-term incentive opportunity through a program dependent on the achievement of company financial objectives for those individuals who most directly influence performance results and thereby supported the following strategic objectives: . maintain competitive total executive compensation; . align executive reward programs with the success of the company; . attract top executive talent to support organizational growth and expansion; . ensure equity among internal position values; and . implement "best practices" in the area of executive compensation. In 2000, executive officers and the Chief Executive Officer participated in two annual variable pay programs: . The major business units within Lennox each have a broad-based variable pay program in which the respective chief operating officer managing the business unit participates. Each unit chief operating officer, in conjunction with the Chief Executive Officer, determines the financial measurements and standards for that business unit's program. In 2000, for company performance levels, the programs generated cash payouts ranging from 0% to 7.2% of annualized base earnings, and were adjusted for individual performance levels. . Each year, the Chief Executive Officer recommends and the Committee approves the performance measurements and targets for the short-term incentive programs. The 2000 short-term incentive program measurements for named executives consisted of sales growth, earnings before interest and taxes and working capital. Threshold, target and maximum performance levels were defined, and target bonus award levels were established for each executive officer. Target incentive award opportunity for the 13

named executive officers ranged from 65% to 75% of their base salary. Executive officers who were also chief operating officers of a business unit have 75% of the target based on their business unit results and 25% based on aggregate Lennox results. One-half of the target payment could be made upon achievement of the minimum performance measurement and up to one and one-half of the target payment could be made upon achievement of the maximum performance measurement. Additionally, the working capital performance measurement functioned as a multiplier of 50% to 150% of the incentive payment determined based on the other measurements. If the profitability minimum was not met, there would not be an incentive payment, regardless if other measurements of the program were achieved. The Committee determined that, due to an executive reorganization in mid- 2000, named executives whose position changed and resulted in being measured in two different business units' short-term incentive programs in 2000 were paid the higher of two calculations: (1) as if they were in their original program for the entire year, or (2) a prorated calculation accounting for the time in each position. Overall Lennox corporate performance resulted in a threshold payment for those named executives in the corporate short-term incentive program. Chief Executive Officer Mr. Norris also participated in the two annual pay programs listed above. Prior to the beginning of 2000, the Committee and the Human Resource Committee of the Board of Directors, along with Mr. Norris, determined his performance goals and their expectations for 2000. The Committee's assessment of Mr. Norris' 2000 performance results included the following: . Lennox continued its North American growth strategy with the January 2000 acquisition of a major network of HVAC dealers. . Throughout 2000, the Lennox executive team focused on integration issues related to recent acquisitions. . Mr. Norris successfully executed a mid-year reorganization to support Lennox' worldwide organization strategy. . In mid-2000, Mr. Norris, in support of Lennox' newly-created worldwide organization and its leadership succession strategy, appointed Mr. Robert E. Schjerven to the new position of Chief Operating Officer of Lennox International Inc. The appointment was subsequently approved by the Board of Directors. Due to an unfavorable weather cycle, an economic downturn, and a slower than anticipated rate of improvement in the integration of acquired businesses, Lennox' overall financial performance results for 2000 were below target. Therefore, Mr. Norris recommended that he not accept a short-term incentive payment for 2000. The Committee accepted that recommendation. Long-Term Incentive Compensation Lennox' executive long-term incentive compensation program is comprised of two vehicles: stock options and performance share awards. Their purpose is to foster and enhance the long-term profitability of the company for the benefit of its stockholders by offering the incentive of long-term rewards to those executives who have proprietary interest in the growth and performance of the company and who have the principal responsibility for long-term profitability of Lennox. Executive Officers Stock Options--Based on internal affordability factors, market-competitive practices outlined in the consultant's market study, and using the Black- Scholes model to determine a market-competitive award value, the Committee reviews and determines annually Lennox' stock option award levels for executive officers. The 2000 award was in the form of non-qualified stock options, exercisable at the fair market value on the grant date and vesting ratably over three years. Options granted in 2000 expire seven years from the date of grant. Performance Share Awards--Based on internal affordability factors and market-competitive practices outlined in the consultant's market study, the Committee reviews and determines annually Lennox' Performance 14

Share Program ("PSP") award levels for executive officers. Awards are made in December for a performance period beginning the following January 1. The performance period for the PSP consists of three consecutive fiscal years commencing each January 1. Minimum, target and maximum performance standard levels, ranging from 50% to 200% of target are established, the achievement of which earns a lesser or greater multiplier of a contingent award granted at the beginning of the three-year period. For awards made in December 2000, the 2001-2003 financial measurement is return on invested capital expressed as a three-year average over the performance period. Contingent awards are expressed in shares of the company's common stock. At the end of the performance period the earned share awards are calculated by applying the performance standards for such period to the contingent share award. Current stock holdings of the executives were not considered when determining the size of the 2000 contingent awards. The 2001--2003 PSP earned awards will be in the form of restricted stock with the following provisions: . Contingent shares awarded at the beginning of the three-year performance period will vest after 10 years; i.e., even if the threshold performance targets are not met, participants will receive the contingent award at 10 years after the grant date, providing they are still employed with the company. . If, at the end of the three-year performance period, actual performance is above threshold but below target, participants will receive only that portion of the contingent shares relative to the actual performance results at the end of the performance period. Those shares are fully- vested at the time of payout. . The remainder of the contingent shares to target will be vested and paid out after an additional seven years (10 years from date of grant), providing the participant is still employed. . If targets are exceeded at the end of the three-year performance period, full payouts will occur and there will be no remaining shares to be vested at a later time. Chief Executive Officer Stock Options--Based on internal affordability factors, market-competitive practices outlined in the consultant's market study, and using the Black- Scholes model to determine a market-competitive award value for the Chief Executive Officer, the Committee reviews and determines annually Mr. Norris' stock option award. In 2000, Mr. Norris received an award of 149,982 non- qualified stock options, exercisable at the fair market value on the grant date and vesting ratably over three years. Options granted in 2000 expire seven years from the date of grant. Performance Share Awards--In December 2000, the Committee awarded Mr. Norris a performance share award under Lennox' 2001--2003 PSP as outlined above. The contingent award level of 48,451 shares was based on internal affordability factors and market-competitive practices as depicted in the consultant's market study. Mr. Norris' earned award in the 2001--2003 program will occur at the end of the three-year performance period and will be determined by attainment of the program's financial goals and company performance. Policy for Compliance with Section 162(m) Section 162(m) of the Internal Revenue Code, as amended, limits a company's ability to deduct compensation paid in excess of $1 million to the Chief Executive Officer and the next four highest paid executives, unless the compensation meets certain stockholder approved performance requirements. It is the company's intent to make awards that qualify as deductible compensation under section 162(m) of such Code whenever possible. However, where granting awards is consistent with the strategic business goals of the company, the Committee reserves the right to make awards that are non-deductible.

Wyant.............. 0 N/A Retirement Plans The named executive officers participate in four Lennox-sponsored retirement plans. The plans are as follows: the pension plan for salaried employees, the profit sharing retirement plan, the supplemental retirement plan, and the profit sharing restoration plan. The supplemental retirement plan and the profit sharing restoration plan are non-qualified plans. Lennox pays the full cost of each of these plans. The pension plan for salaried employees is a floor offset plan. A target benefit is calculated using credited service and final average pay during the five highest consecutive years. The benefit is currently based on 1.00% of final average pay, plus 0.60% of final average pay above Social Security covered compensation, multiplied by the number of years of credited service, not to exceed 30 years. Employees vest after five years of service and may commence unreduced benefits at age 65. If specified age and service requirements are met, benefits may commence earlier on an actuarially reduced basis. At time of retirement, a participant may choose one of five optional forms of payment. The supplemental retirement plan permits income above Internal Revenue Service limitations to be considered in determining final average pay, doubles the rate of benefit accrual, limits credited service to 15 years and permits early retirement on somewhat more favorable terms than the pension plan. The profit sharing retirement plan is a defined contribution plan. Profit sharing contributions, as determined by the Board of Directors, are credited annually to participants' accounts based on pay. Participants are fully vested after six years. The assets of the plan are employer directed. Distributions may occur at separation of employment and can be paid directly to the participant. The profit sharing restoration plan permits accruals that otherwise could not occur because of Internal Revenue Service limitations on compensation. 18

The estimates of annual retirement benefits shown in the following table are the targets established by the supplemental retirement plan.

Compensation for these purposes includes salary and bonuses, and excludes extraordinary compensation such as benefits from the Plan or its predecessor plans. Bonus numbers used in these calculations, as per plan requirements, are the bonuses actually paid in those years. In the Summary Compensation Table, the 2000 bonus reported is the bonus earned in 2000, but not paid until 2001. As of December 31, 2000, the final average pay and the eligible years of credited service for each of the named executive officers was as follows: Mr. Norris, $1,217,181--40.25 years; Mr. Schjerven, $586,877--14.80 years; Mr. Wyant, $510,809--10.30 years; Mr. French, $497,422--11.80 years; and Mr. Ashenhurst, $407,322--12.00 years. Employment Agreements Lennox has entered into employment agreements with the named executive officers which are identical except for the name of the named executive officer who is a party to the agreement and the date of the agreement. These employment agreements establish the basis of compensation and assignments, and contain post-employment covenants covering confidential information, the diverting of employees, vendors and contractors and the solicitation of customers. These agreements also establish binding arbitration as the mechanism for resolving disputes and provide benefits and income in the event employment terminates under specified circumstances. On January 1 of each year, the agreements automatically renew for an additional year, unless either party notifies the other, in writing, at least 30 days prior to such date, of a decision not to renew the agreement. If Lennox terminates the employee prior to the expiration of the term of the agreement or if Lennox does not renew the agreement for any reason other than for cause, the employee will be entitled to receive monthly payments of the greater of the employee's base salary for the remainder of the agreement's term or three months of the employee's base salary in addition to any other compensation or benefits applicable to an employee at the employee's level. If Lennox terminates the employee other than for cause, including Lennox' non-renewal of the agreement, and the employee agrees to execute a written general release of any and all possible claims against Lennox existing at the time of termination, Lennox will provide the employee with an enhanced severance package. That package includes payment of the employee's base monthly salary for a period of twenty-four months following the date of termination, a lump sum in the amount which totals any short-term bonus payments actually paid to the employee over the twenty-four month period prior to the date of termination, a lump sum payment of a sum equal to ten percent of the employee's annual base salary in effect at the time of termination in lieu of perquisites lost, and forgiveness of COBRA premiums due for group health insurance coverage for up to eighteen months while the employee remains unemployed. If the employee remains unemployed at the end of eighteen months, the equivalent of the COBRA premium will be paid to the employee on a month to month basis for up to six additional months while the employee remains unemployed. Outplacement services are provided or, at the 19

employee's election, a lump-sum payment of 10% of the employee's annual base salary will be made to the employee in lieu of those services. Additionally, the employee's beneficiary will receive a lump-sum death benefit equivalent to six months of the employee's base salary should the employee die while entitled to enhanced severance payments. Change of Control Employment Agreements Lennox has entered into change of control employment agreements with the named executive officers which are identical except for the name of the named executive officer who is a party to the agreement and the date of the agreement. The change of control agreements provide for certain benefits under specified circumstances if the officer's employment is terminated following a change of control transaction involving Lennox. The change of control agreements are intended to provide protections to the officers that are not afforded by their existing employment agreements, but not to duplicate benefits provided by the existing employment agreements. The term of the change of control agreements is generally two years from the date of a potential change of control, as discussed below, or a change of control. If the officer remains employed at the conclusion of such term, the officer's existing employment agreement will continue to apply. The employment rights of the named executive officers under the change of control agreements would be triggered by either a change of control or a potential change of control. Following a potential change of control, the term of the change of control agreement may terminate but the change of control agreement will remain in force and a new term of the agreement will apply to any future change of control or potential change of control, if either (a) the Board of Directors determines that a change of control is not likely or (b) the named executive officer, upon proper notice to Lennox, elects to terminate his term of the change of control agreement as of any anniversary of the potential change of control. A "change of control" generally includes the occurrence of any of the following: (a) any person, other than specified exempt persons, including Lennox and its subsidiaries and employee benefit plans, becoming a beneficial owner of 35% or more of the shares of Lennox voting securities; (b) a change in the identity of a majority of the Board of Directors, unless approved by a majority of the incumbent members of the Board of Directors; (c) approval by the stockholders of a reorganization, merger or consolidation in which: (1) existing stockholders would own 65% or less of the voting securities of the surviving entity; (2) a person, other than specified exempt persons, would own 35% or more of the voting securities of the surviving entity; or (3) less than a majority of the board of the surviving entity would consist of the then incumbent members of the Board of Directors; or (d) approval by the stockholders of a liquidation or dissolution of Lennox, unless such liquidation or dissolution involves a sale to a company of which following such transaction: (1) more than 65% of the voting securities of such company would be owned by existing stockholders; (2) no person, other than specified exempt persons, would own 35% or more of the voting securities of such company; and (3) at least a majority of the board of directors of such company would consist of the then incumbent members of the board of directors. A "potential change in control" generally includes any of the following: . commencement of a tender or exchange offer for voting stock that, if consummated, would result in a change of control; . Lennox entering into an agreement which, if consummated, would constitute a change of control; . commencement of a contested election contest subject to proxy rules; or . occurrence of any other event that the Board of Directors determines could result in a change of control. 20

During the term of the change of control agreement, an officer's position, authority, duties and responsibilities may not be diminished, and all forms of compensation, including salary, bonus, regular salaried employee plan benefits, stock options, restricted stock and other awards, must continue on a basis no less favorable than at the beginning of the term of the change of control agreement and, in the case of specified benefits, must continue on a basis no less favorable in the aggregate than the most favorable application of such benefits to any of Lennox' employees. If an officer terminates employment during the term of the change of control agreement for good reason or for any reason during a window period (the 90-day period commencing 366 days after any change of control), Lennox will pay the officer: . his then unpaid current salary and a pro rata portion of the highest bonus earned during the preceding three years, as well as previously deferred compensation and accrued vacation time; . a lump-sum cash payment equal to the sum of three times the officer's annual base salary and three times the highest annual bonus paid or awarded to the officer during the preceding three fiscal years; . a lump-sum cash payment equal to the sum of three times the officer's annual base salary and three times the highest annual bonus paid or awarded during the preceding three fiscal years, to reflect the equity component of the officer's compensation; . a lump-sum cash payment equal to the sum of 15% of the officer's annual base salary, in lieu of outplacement services, and three times 15% of the annual base salary that would have been paid or awarded to the officer during the fiscal year that includes the date of termination, for the perquisites component of the officer's compensation; . for purposes of Lennox' supplemental retirement plan and Lennox' profit sharing restoration plan, three additional years added to both his service and age criteria; and . continued coverage under Lennox' employee welfare benefits plans for up to four and one-half years. In addition, all options, restricted stock and other compensatory awards held by the officer will immediately vest and become exercisable, and the term of these awards will be extended for up to three years following termination of employment. The officer may also elect to cash out equity-based compensatory awards at the highest price per share paid by specified persons during the term of the change of control agreement or the six-month period prior to the beginning of the term of the change of control agreement. In the event of any contest concerning a change of control agreement, unless the officer's claim is found by a court to be frivolous, Lennox has no right of offset, the officer is not required to mitigate damages, and Lennox agrees to pay any legal fees incurred by the officer in connection with such contest. Lennox also agrees to pay all amounts owing to the officer during any period of dispute, subject only to the officer's agreement to repay any amounts to which he is determined not to be entitled. The change of control agreements provide for a tax gross-up in the event that specified excise taxes are applicable to payments made by Lennox under a change of control agreement or otherwise. The change of control agreements require the officer to maintain the confidentiality of Lennox' information, and, for a period of 24 months following his termination of employment, to avoid any attempts to induce Lennox' employees to terminate their employment with Lennox. Indemnification Agreements Lennox has entered into indemnification agreements with its directors and a number of its executive officers. Each of the indemnification agreements is identical except for the name of the director or executive officer who is a party to the agreement and the date of the agreement. Under the terms of the indemnification agreements, Lennox has generally agreed to indemnify, and advance expenses to, each indemnitee to the fullest extent permitted by applicable law on the date of the agreements and to such greater extent as applicable law may at a 21

future time permit. In addition, the indemnification agreements contain specific provisions pursuant to which Lennox has agreed to indemnify each indemnitee: . if such person is, by reason of his or her status as a director, nominee for director, officer, agent or fiduciary of Lennox or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise with which such person was serving at Lennox' request, any such status being referred to as a "corporate status," made or threatened to be made a party to any threatened, pending or completed action, suit, arbitration, alternative dispute resolution mechanism, investigation or other proceeding, other than a proceeding by or in the right of Lennox; . if such person is, by reason of his or her corporate status, made or threatened to be made a party to any proceeding brought by or in the right of Lennox to procure a judgment in its favor, except that no indemnification shall be made in respect of any claim, issue or matter in such proceeding as to which such indemnitee shall have been adjudged to be liable to Lennox if applicable law prohibits such indemnification, unless and only to the extent that a court shall otherwise determine; . against expenses actually and reasonably incurred by such person or on his or her behalf in connection with any proceeding to which such indemnitee was or is a party by reason of his or her corporate status and in which such indemnitee is successful, on the merits or otherwise; . against expenses actually and reasonably incurred by such person or on his or her behalf in connection with a proceeding to the extent that such indemnitee is, by reason of his or her corporate status, a witness or otherwise participates in any proceeding at a time when such person is not a party in the proceeding; and . against expenses actually and reasonably incurred by such person in certain judicial adjudications of or awards in arbitration to enforce his or her rights under the indemnification agreements. In addition, under the terms of the indemnification agreements, Lennox has agreed to pay all reasonable expenses incurred by or on behalf of an indemnitee in connection with any proceeding, whether brought by or in the right of Lennox or otherwise, in advance of any determination with respect to entitlement to indemnification and within 15 days after the receipt by Lennox of a written request from such indemnitee for such payment. In the indemnification agreements, each indemnitee has agreed that he or she will reimburse and repay Lennox for any expenses so advanced to the extent that it shall ultimately be determined that he or she is not entitled to be indemnified by Lennox against such expenses. The indemnification agreements also include provisions that specify the procedures and presumptions which are to be employed to determine whether an indemnitee is entitled to indemnification. In some cases, the nature of the procedures specified in the indemnification agreements varies depending on whether Lennox has undergone a change in control. CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS John W. Norris, Jr., Lennox' Chairman of the Board, David H. Anderson, Richard W. Booth and David V. Brown, each a director of Lennox, as well as other Lennox stockholders, 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 Investment, L.L.C. owns 70% of AOC Development II, L.L.C., which owns substantially all of One Lake Park, L.L.C. Lennox is leasing part of an office building owned by One Lake Park, L.L.C. for use as the Lennox corporate headquarters. The lease has a term of 25 years and the lease payments for 2000 totaled approximately $2.7 million. Lennox also leases a portion of Lennox Center, a retail complex owned by AOC Development, L.L.C., for use as offices. The Lennox Center lease has a term of three (3) years and the lease payments for 2000 totaled approximately $119,200. AOC Land Investment, L.L.C. also owns 70% of AOC Development, L.L.C. Lennox believes that the terms of its leases with One Lake Park, L.L.C. and AOC Development, L.L.C. are at least as favorable as could be obtained from unaffiliated third parties. 22

From time to time Lennox has entered into stock disposition agreements, which allowed its executive officers, directors, and stockholders to borrow money and use its capital stock held by them as collateral. The stock disposition agreements provide that in the event of a default on the underlying loan, Lennox will do one of several things, including registering the capital stock under the Securities Act of 1933, finding a buyer to purchase the stock or purchasing the stock itself. To date, there has not been a default under any of these agreements. As of March 15, 2001, there was one stock disposition agreement in existence, entered into in 1997, covering approximately 250,000 shares of Lennox common stock. Lennox will not enter into these type of agreements in the future. These transactions were not the result of arms-length negotiations. Accordingly, certain of the terms of these transactions may be more or less favorable to Lennox than might have been obtained from unaffiliated third parties. Lennox does not intend to enter into any future transactions in which its directors, executive officers or principal stockholders and their affiliates have a material interest unless such transactions are approved by a majority of the disinterested members of its Board of Directors and are on terms that are no less favorable to it than those that it could obtain from unaffiliated third parties. OWNERSHIP OF LENNOX COMMON STOCK The following table contains information regarding the beneficial ownership of Lennox common stock as of March 1, 2001 by the following individuals: . each person known by Lennox to own more than 5% of the outstanding shares of Lennox common stock; . each of Lennox' directors; . each named executive officer of Lennox; and . all executive officers and directors of Lennox as a group. All persons listed have an address in care of Lennox' principal executive offices which are located at 2140 Lake Park Boulevard, Richardson, Texas 75080. The information contained in this table reflects "beneficial ownership" as defined in Rule 13d-3 of the Securities Exchange Act of 1934. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of Lennox common stock subject to options held by that person that were exercisable on March 1, 2001 or would be exercisable within 60 days following March 1, 2001 are considered outstanding. However, such shares are not considered outstanding for the purpose of computing the percentage ownership of any other person. To Lennox' knowledge and unless otherwise indicated, each stockholder has sole voting and investment power over the shares listed as beneficially owned by such stockholder, subject to community property laws where applicable. Percentage of ownership is based on 56,050,163 shares of common stock outstanding as of March 1, 2001. 23

COMPARISON OF TOTAL STOCKHOLDER RETURN The following graph compares the cumulative total returns of Lennox, the Standard & Poor's Small-Cap 600 Index and a peer group of U.S. industrial manufacturing and service companies in the heating, ventilation, air conditioning and refrigeration businesses from July 29, 1999, the date of the Lennox initial public offering, through December 31, 2000. The chart assumes that $100 was invested on July 29, 1999, with dividends reinvested. Peer group returns are weighted by market capitalization. The peer group includes AAON, Inc., American Standard Companies Inc., Comfort Systems USA, Inc., Maytag Corporation, Modine Corporation, Watsco, Inc., Whirlpool Corporation, and York International Corporation. Hussman International, Inc., which was in the peer group in 1999, was acquired by Ingersoll-Rand Company in 2000, and is no longer included in the peer group. [Performance Graph] LENNOX S&P SMALL INTERNATIONAL INC CAP 600 PEER GROUP ----------------- --------- ---------- July 1999 ................ 100.00 100.00 100.00 1999 ................ 49.73 107.02 78.76 2000 ................ 43.57 119.65 66.30 ADDITIONAL INFORMATION Quorum Required A quorum of Lennox stockholders is necessary to have a valid meeting of stockholders. A majority of the shares of Lennox common stock issued and outstanding and entitled to vote on the record date must be represented in person or by proxy at the annual meeting in order for a quorum to be established. Abstentions and broker "non-votes" count as present for establishing a quorum. Shares held by Lennox in its treasury or by any majority-owned subsidiary or Lennox do not count toward a quorum. A broker non-vote occurs on an item when a broker is not permitted to vote on that item without instruction from the beneficial owner of the shares and no instruction is given. We expect, in the event that a quorum is not present at the annual meeting, the meeting will be adjourned or postponed to solicit additional proxies. 25

Vote Required Only stockholders of record at the close of business on March 1, 2001 are entitled to notice of and to vote at the meeting. There were 56,050,163 shares of common stock of Lennox outstanding at the close of business on that date, all of which will be entitled to vote. Holders of shares of common stock are entitled to one vote per share held of record in their names on the record date on all matters. Stockholders do not have cumulative voting rights. The election of each director and approval of the amendment to the Purchase Plan require a plurality of the votes cast. Votes withheld will be deemed not to have been cast. Abstentions and broker non-votes have no effect on determinations of plurality, except to the extent that they affect the total votes received by any particular candidate or proposal. Shares Held in Street Name Under the applicable rules of the New York Stock Exchange, brokers who hold shares in "street names" (i.e., in the name of a broker, bank or other record holder) for customers who are the beneficial owners of those shares may be prohibited from giving a proxy to vote those customers' shares with respect to the proposals to be voted on at the annual meeting in the absence of specific instructions from the customer. Lennox stockholders whose shares are held in street name must either direct the record holder of their shares as to how to vote their shares or obtain a proxy from the record holder to vote at the annual meeting. Telephone and Internet Voting Shares Directly Registered in the Name of the Stockholder. Stockholders with shares registered directly with Mellon Investor Services may vote by telephone by calling Mellon Investor Services at (800) 840-1208 or by Internet at http://www.eproxy.com/lii. Shares Registered in the Name of a Brokerage Firm or Bank. A number of brokerage firms and banks offer telephone and Internet voting options. These programs differ from the program provided by Mellon Investor Services for shares registered in the name of the stockholder. Check the information forwarded by your bank, broker or other holder of record to see which options are available to you. Revoking Proxies Lennox stockholders of record may revoke their proxies at any time prior to the time their proxies are voted at the annual meeting. Proxies may be revoked by written notice, including by telegram or facsimile, to the Secretary of Lennox, by a later-dated proxy signed and returned by mail or by attending Lennox' annual meeting and voting in person. Attendance at the annual meeting will not in and of itself constitute a revocation of a proxy. Any written notice of a revocation of a proxy must be sent so as to be delivered before the taking of the vote at the annual meeting to: Lennox International Inc. 2140 Lake Park Blvd. Richardson, TX 75080 Facsimile: (972) 497-6660 Attention: Carl E. Edwards, Jr. Other Business; Adjournments We are not aware of any other business to be acted upon at the annual meeting. If, however, other matters are properly brought before the meeting, or any adjourned meeting, your proxies will have discretion to act on those matters or to adjourn the meeting, according to their best judgment. Adjournment of the annual meeting may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made at any time by stockholders representing a majority of the votes present in person or by proxy at the applicable special meeting, whether or not a quorum exists, without further notice other than by an announcement made at the meeting. 26

Proxy Solicitation The cost of solicitation of proxies will be paid by Lennox. In addition to solicitation by mail, the directors, officers and employees of Lennox may also solicit proxies from stockholders by telephone, facsimile, telegram, electronic mail or in person. We will also make arrangements with brokerage houses and other custodians, nominees and fiduciaries to send the proxy materials to beneficial owners. Upon request, we will reimburse those brokerage houses and custodians for their reasonable expenses in so doing. Stockholder Proposals If you wish to submit a proposal for possible inclusion in our 2002 proxy material, we must receive your notice, in accordance with rules of the Securities and Exchange Commission, on or before November 28, 2001. If you wish to submit a proposal at the 2002 Annual Meeting (but not seek inclusion of the proposal in our proxy material), we must receive your notice, in accordance with the Lennox Bylaws, not less than 60 nor more than 90 days in advance of such meeting. Section 16(a) Beneficial Ownership Reporting Compliance Section 16 of the Securities Exchange Act of 1934 requires Lennox' directors and executive officers and any person owning more than 10% of Lennox common stock to file reports of ownership and changes in ownership of Lennox common stock with the Securities and Exchange Commission and to furnish Lennox with copies of these reports. Based solely upon a review of the reports and related information furnished to Lennox, Lennox believes that all required reports were filed on time during 2000. Independent Auditors At their regularly scheduled meetings on March 15-16, 2001, the Audit Committee and the Board of Directors will consider approval of Arthur Andersen LLP as independent auditors for Lennox for fiscal year 2001. Representatives of Arthur Andersen LLP are expected to be present, and to be available to respond to appropriate questions, at the Annual Meeting. They will have the opportunity to make a statement if they desire to do so; as of this date, they have indicated that they do not. By Order of the Board of Directors /s/ Carl E. Edwards, Jr. Carl E. Edwards, Jr. Executive Vice President, Chief Legal Officer and Secretary Richardson, Texas March 27, 2001 27

APPENDIX B LENNOX INTERNATIONAL INC. EMPLOYEE STOCK PURCHASE PLAN (As Proposed To Be Amended Effective January 1, 2001) 1. Purpose The Lennox International Inc. Employee Stock Purchase Plan (the "Plan") is designed to encourage and assist all employees of Lennox International Inc., a Delaware corporation ("Lennox") and Subsidiaries (as defined in Section 4) (hereinafter collectively referred to as the "Company"), where permitted by applicable laws and regulations, to acquire an equity interest in Lennox through the purchase of shares of common stock, par value $.01 per share, of Lennox ("Common Stock"). It is intended that this Plan constitute an "employee stock purchase plan" within the meaning of Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). 2. Administration of the Plan The Plan shall be administered and interpreted by the Compensation Committee (the "Committee") of the Board of Directors of Lennox (the "Board") or such other committee as may be appointed by the Board or its designee, which Committee shall consist of at least two persons. The Committee shall supervise the administration and enforcement of the Plan according to its terms and provisions and shall have all powers necessary to accomplish these purposes and discharge its duties hereunder including, but not by way of limitation, the power to (i) employ and compensate agents of the Committee for the purpose of administering the accounts of participating employees; (ii) construe and interpret the Plan; (iii) determine all questions of eligibility; and (iv) compute the amount and determine the manner and time of payment of all benefits according to the Plan. The Committee may act by decision of a majority of its members at a regular or special meeting of the Committee or by decision reduced to writing and signed by all members of the Committee without holding a formal meeting. 3. Nature and Number of Shares The Common Stock subject to issuance under the terms of the Plan shall be authorized but unissued shares, previously issued shares reacquired and held by Lennox or shares purchased on the open market. The aggregate number of shares that may be issued under the Plan shall not exceed 2,575,000 shares of Common Stock, which include the original 825,000 shares and an additional 1,750,000 shares added by this amendment. All shares purchased under the Plan, regardless of source, shall be counted against the 2,575,000 share limitation. In the event of any reorganization, stock split, reverse stock split, stock dividend, combination of shares, merger, consolidation, offering of rights or other similar change in the capital structure of Lennox, the Committee may make such adjustment, if any, as it deems appropriate in the number, kind and purchase price of the shares available for purchase under the Plan and in the maximum number of shares that may be issued under the Plan, subject to the approval of the Board and in accordance with Section 19. 4. Eligibility Requirements Each "Employee" (as hereinafter defined), except as described in the next following paragraph, shall become eligible to participate in the Plan in accordance with Section 5 on the first "Enrollment Date" (as defined therein) following employment by the Company. Participation in the Plan is voluntary. 1

The following Employees are not eligible to participate in the Plan: i. Employees who would, immediately upon enrollment in the Plan, own directly or indirectly, or hold options or rights to acquire, an aggregate of five percent or more of the total combined voting power or value of all outstanding shares of all classes of the Company or any subsidiary (in determining stock ownership of an individual, the rules of Section 424(d) of the Code shall be applied, and the Committee may rely on representations of fact made to it by the Employee and believed by it to be true); and ii. Employees who are customarily employed by the Company less than 20 hours per week or less than five months in any calendar year. "Employee" shall mean any individual employed by Lennox or any Subsidiary (as hereinafter defined). "Subsidiary" shall mean any corporation (a) which is in an unbroken chain of corporations beginning with Lennox if, on or after the Effective Date, each of the corporations other than the last corporation in the chain owns stock possessing 50 percent or more of the total combined voting power of all classes of stock in one of the other corporations in the chain and (b) which has adopted the Plan with the approval of the Committee. 5. Enrollment Each eligible Employee of the Company on July 28, 1999, may enroll in the Plan as of July 29, 1999 (the "Effective Date"). Each other eligible Employee of the Company who thereafter becomes eligible to participate may enroll in the Plan as of January 1, 2000, or, if later, the first January 1 or July 1 following the date he first meets the eligibility requirements of Section 4. Any eligible Employee not enrolling in the Plan when first eligible may enroll in the Plan as of any subsequent January 1 or July 1. Any eligible Employee may enroll or re- enroll in the Plan as of the dates hereinabove prescribed or such other specific dates established by the Committee from time to time ("Enrollment Dates"). In order to enroll, an eligible Employee must complete, sign and submit the appropriate form to the person designated, or otherwise satisfy any telephonic or electronic enrollment procedure established, by the Committee. 6. Method of Payment Payment for shares is to be made as of the applicable "Purchase Date" (as defined in Section 9) through payroll deductions on an after-tax basis (with no right of prepayment) over the Plan's designated purchase period (the "Purchase Period"), with the first such deduction commencing as soon as administratively practicable following the Enrollment Date and after the Employee has satisfied the enrollment requirements of Section 5. Each Purchase Period under the Plan except the first shall be a period of six months beginning on each January 1 and July 1 and ending on the following June 30 or December 31 or such other period as the Committee may prescribe. Each participating Employee (hereinafter referred to as a "Participant") will authorize deductions from his pay for each payroll period during the Purchase Period and such amounts will be deducted in conformity with his employer's payroll deduction schedule. Each Participant may elect to make contributions each pay period in amounts not less than one percent of compensation and not more than 10 percent of compensation (or such other percentages as the Committee may establish from time to time before an Enrollment Date for all purchases to occur during the relevant Purchase Period). For all purposes of the Plan, compensation shall mean salary or wages plus bonuses, overtime and any commissions paid. In establishing other percentages of permitted contributions, the Committee may take into account the "Maximum Share Limitation" (as defined in Section 8). The rate of contribution shall be designated by the Participant at the time of enrollment. A Participant may elect to increase or decrease the rate of contribution effective as of the first day of a Purchase Period by giving prior written notice to the person designated by the Committee on the appropriate form, or by such other method or procedure prescribed by the Committee. A Participant may not elect to increase or decrease the rate of contribution during a Purchase Period. A Participant may 2

suspend payroll deductions at any time during the Purchase Period, by giving prior written notice to the person designated by the Committee on the appropriate form, or by such other method or procedure prescribed by the Committee. A Participant's election to suspend his payroll deductions will be treated as an election to withdraw his entire contributions for the current Purchase Period. Any Participant who withdraws his contributions will receive, as soon as administratively practicable, the amount accumulated for the Participant during the Purchase Period. All such contributions shall be returned through the normal payroll system. Any Participant who suspends payroll deductions and withdraws contributions during any Purchase Period cannot resume payroll deductions during such Purchase Period and must re-enroll in the Plan in order to participate in the next Purchase Period. Except in the case of a Participant's suspension of payroll deductions or termination of employment, and subject in all cases to the Maximum Share Limitation, the amount in a Participant's account at the end of the Purchase Period will be applied to the purchase of Common Stock. 7. Crediting of Contributions and Dividends Contributions shall be credited to a bookkeeping account maintained for such purpose for each Participant as soon as administratively practicable after payroll withholding. Participant contributions will not be maintained in segregated accounts and will not be credited with interest at any time. Except as otherwise provided pursuant to a procedure established by the Committee, dividends on shares held in a Participant's account in the Plan will be used to purchase shares of Common Stock. Purchases of shares with dividends paid on Common Stock held in a Participant's account shall be made on the open market by the entity designated by the Committee to assist it with the administration of the Plan (the "Custodian"); provided, however, that if the Company has notified the Custodian that it is willing to sell authorized but unissued shares or previously issued shares that have been reacquired and held by Lennox, the Custodian shall, at its election, purchase any shares made available by the Company at a price equal to the Fair Market Value of such shares (determined as provided in Section 9) on the business day next preceding the date of such purchase. 8. Grant of Right to Purchase Shares on Enrollment Enrollment in the Plan by an Employee on an Enrollment Date will constitute the grant by the Company to the Participant of the right to purchase shares of Common Stock under the Plan. Re-enrollment by a Participant in the Plan will constitute a grant by the Company to the Participant of a new opportunity to purchase shares on the Enrollment Date on which such re-enrollment occurs. A Participant who has not (a) terminated employment or (b) withdrawn his contributions from the Plan, will have shares of Common Stock purchased for him on the applicable Purchase Date, and he will automatically be re-enrolled in the Plan on the Enrollment Date immediately following the Purchase Date on which such purchase has occurred, unless each Participant notifies the person designated by the Committee in the appropriate manner that he elects not to re- enroll. Each right to purchase shares of Common Stock under the Plan during a Purchase Period shall have the following terms: i. the right to purchase shares of Common Stock during a particular Purchase Period shall expire on the earlier of: (A) the completion of the purchase of shares on the Purchase Date occurring in the Purchase Period, or (B) the date on which participation of such Participant in the Plan terminates for any reason; ii. payment for shares purchased will be made only through payroll withholding and the application of dividends, if applicable, in accordance with Sections 6 and 7; iii. purchase of shares will be accomplished only in accordance with Section 9; iv. the price per share will be determined as provided in Section 9; 3

v. the right to purchase shares (taken together with all other such rights then outstanding under this Plan and under any other similar stock purchase plans of the Company) will in no event give the Participant the right to purchase a number of shares during a calendar year in excess of the number of shares of Common Stock derived by dividing $25,000 by the Fair Market Value of the Common Stock (the "Maximum Share Limitation") on the applicable Grant Date determined in accordance with Section 9. If a Participant has purchased less than the maximum number of shares permitted by this paragraph (v) during the first Purchase Period in a calendar year, the maximum number of shares permitted to be purchased by the Participant during the second Purchase Period in such calendar year shall be determined by dividing the Fair Market Value of a share of Common Stock on the Grant Date for the second Purchase Period into the difference between $25,000 and the value of the shares purchased during the first Purchase Period, calculated by using the Fair Market Value of such shares on the first Grant Date during the calendar year; and vi. the right to purchase shares will in all respects be subject to the terms and conditions of the Plan, as interpreted by the Committee from time to time. 9. Purchase of Shares The right to purchase shares of Common Stock granted by the Company under the Plan is for the term of a Purchase Period. The fair market value of the Common Stock ("Fair Market Value") to be purchased during such Purchase Period will be determined first as the closing composite sales price per share of the Common Stock in the New York Stock Exchange Composite Transactions Quotations on the first trading days of the calendar months of January and July, or such other trading dates designated by the Committee (the "Grant Date"). The Fair Market Value of the Common Stock will again be determined in the same manner on the last trading days of the calendar months of June and December, or such other trading dates designated by the Committee (the "Purchase Date"). Notwithstanding the foregoing, the Fair Market Value of Common Stock to be purchased during the Purchase Period beginning on the Effective Date shall be the initial price to public as set forth on the cover page of the prospectus relating to the initial public offering of shares of Common Stock. In no event, however, shall the Committee, in the exercise of its discretion, designate a Purchase Date that fails to meet the requirements of Section 423(b)(7) of the Code. These dates constitute the date of grant and the date of exercise for valuation purposes of Section 423 of the Code. As of the Purchase Date, the Committee shall apply the funds then credited to each Participant's account to the purchase of shares of Common Stock. The cost to the Participant for the shares purchased during a Purchase Period shall be the lower of: i. 85 percent of the Fair Market Value of Common Stock on the Grant Date; or ii. 85 percent of the Fair Market Value of Common Stock on the Purchase Date. In the case of any Participant whose compensation is not paid in U.S. dollars, amounts accumulated in such Participants' account shall be converted into U.S. dollars on each Purchase Date by reference to the New York foreign exchange selling rates reported in The Wall Street Journal for the last business day immediately preceding such Purchase Date. Certificates evidencing shares purchased shall be delivered to the Custodian or delivered to the Participant (if the Participant has elected by written notice to the Committee to receive the certificate) as soon as administratively practicable after the Purchase Date; however, certificates shall not be delivered to the Participant within 18 months of the Purchase Date of the underlying shares, except as otherwise provided herein. Notwithstanding the foregoing, Participants shall be treated as the record owners of their shares effective as of the Purchase Date. Shares that are held by the Custodian shall be held in book entry form. Each Participant shall be credited with the number of whole and fractional shares acquired on the Purchase Date with the funds credited to the Participant's account on such Purchase Date. Any Participant (i) who purchases stock at the end of a Purchase Period and is not re-enrolled in the Plan for the next Purchase Period or (ii) who withdraws his contributions from the Plan prior to the next Purchase Date shall 4

have a certificate for the number of whole shares held in his account and cash for any fractional share in his account retained by the Custodian. Such Participant may elect to receive a certificate for the number of whole shares held in his account 18 months after such shares were purchased. This 18-month requirement may be waived by the Committee, in its sole discretion. Until such certificates are distributed to the Participant, the Participant will not be permitted to transfer ownership of the certificates except as contemplated by Section 10 or Section 14 of the Plan. Any Participant who terminates employment will receive a certificate for the number of shares held in his account and cash for any fractional share and any accumulated contributions. If for any reason the purchase of shares with a Participant's allocations to the Plan exceeds or would exceed the Maximum Share Limitation, the excess amounts shall be refunded to the Participant as soon as practicable after such excess has been determined to exist. If as of any Purchase Date the shares authorized for purchase under the Plan are exceeded, enrollments shall be reduced proportionately to eliminate the excess. Any funds that cannot be applied to the purchase of shares due to excess enrollment shall be refunded as soon as administratively practicable. The Committee in its discretion may also provide that excess enrollments may be carried over to the next Purchase Period under this Plan or any successor plan according to the regulations set forth under Section 423 of the Code. 10. Withdrawal of Shares and Sale of Shares (a) A Participant may elect to withdraw at any time (without withdrawing from participation in the Plan) shares that have been held in his account for at least 18 months by giving notice to the person designated by the Committee in the appropriate manner. Upon receipt of such notice from the person designated by the Committee, the Custodian will arrange for the issuance and delivery of such shares held in the Participant's account as soon as administratively practicable. (b) Notwithstanding anything in the Plan to the contrary, a Participant may sell shares that are held in his account, including shares that have been held in his account for less than 18 months, by giving notice to the person designated by the Committee in the appropriate manner. Upon receipt of such notice from the person designated by the Committee, the Custodian will arrange for the sale of such Participant's shares. Any sale will be deemed to occur on the last business day of the month in which the Participant provides such notice to the person designated by the Committee, or at such other time as the Committee shall establish. The proceeds of any sale under this subsection 10(b), less any associated commissions and required withholding for taxes, shall be paid to the Participant as soon as practicable after the sale. 11. Termination of Participation The right to participate in the Plan terminates immediately when a Participant ceases to be employed by the Company for any reason whatsoever (other than the death of the Participant, but including retirement and disability) or the Participant otherwise becomes ineligible. Participation terminates immediately after the Purchase Date if the Participant is not re-enrolled in the Plan for the next Purchase Period or if the Participant has suspended payroll deductions during any Purchase Period and has not re-enrolled in the Plan for the next Purchase Period. For purposes of the Plan, a Participant is not deemed to have terminated his employment if he transfers employment from Lennox to a Subsidiary, or vice versa, or transfers employment between Subsidiaries. An individual shall also not lose the right to have shares purchased for his account if he is transferred to a corporation that qualifies as a Subsidiary except that it has not adopted the Plan. In any such case shares will be purchased with amounts maintained in such account as of the date of such transfer. The Participant shall not participate thereafter unless he again becomes employed by the Company. 12. Unpaid Leave of Absence Unless the Participant has voluntarily withdrawn his contributions from the Plan, shares will be purchased for his account on the Purchase Date next following commencement of an unpaid leave of absence by such Participant, provided such leave does not constitute a termination of employment. The number of shares to be purchased will be determined by applying to the purchase the amount of the 5

Participant's contributions made up to the commencement of such unpaid leave of absence. If the Participant's unpaid leave of absence both commences and terminates during the same Purchase Period and he has resumed eligible employment prior to the Purchase Date related to that Purchase Period, he may also resume payroll deductions immediately, and shares will be purchased for him on such Purchase Date as otherwise provided in Section 9. 13. Designation of Beneficiary Each Participant may designate one or more beneficiaries in the event of death and may, in his sole discretion, change such designation at any time. Any such designation shall be effective upon receipt by the person designated by the Committee and shall control over any disposition by will or otherwise. As of the next Purchase Date following the death of a Participant, amounts credited to his account shall be, at the election of the Participant's designated beneficiary or, in the absence of such designation, of the executor, administrator or other legal representative of the Participant's estate, paid in cash or applied to the purchase of shares as provided in Section 9, and in such case a certificate for any shares shall be delivered to such person. Such payment or delivery shall relieve the Company of further liability to the deceased Participant with respect to the Plan. If more than one beneficiary is designated, each beneficiary shall be permitted to make such an election, unless the Participant has given express contrary instructions. 14. Assignment Except as provided in Section 13, the rights of a Participant under the Plan will not be assignable or otherwise transferable by the Participant, other than by will or the laws of descent and distribution. No purported assignment or transfer of such rights of a Participant under the Plan, whether voluntary or involuntary, by operation of law or otherwise, shall vest in the purported assignee or transferee any interest or right therein whatsoever, but immediately upon such assignment or transfer, or any attempt to make the same, such rights shall terminate and become of no further effect. If this provision is violated, the Participant's election to purchase Common Stock shall terminate, and the only obligation of the Company remaining under the Plan will be to pay to the person entitled thereto the amount then credited to the Participant's account. No Participant may create a lien on any funds, securities, rights or other property held for the account of the Participant under the Plan, except to the extent that there has been a designation of beneficiaries in accordance with the Plan, and except to the extent permitted by will or the laws of descent and distribution if beneficiaries have not been designated. A Participant's right to purchase shares under the Plan shall be exercisable during the Participant's lifetime only by him. 15. Costs All costs and expenses incurred in administering this Plan shall be paid by the Company. Any brokerage fees for the sale or transfer of shares purchased under the Plan shall be paid by the Participant. 16. Reports At the end of each Purchase Period, the Company shall provide or cause to be provided to each Participant a report of his contributions and the number of shares of Common Stock purchased with the amount credited to the Participant's account as of the Purchase Date for such Purchase Period. 17. Equal Rights and Privileges All eligible Employees shall have equal rights and privileges with respect to the Plan so that the Plan qualifies as an "employee stock purchase plan" within the meaning of Section 423 or any successor provision of the Code and related regulations. Any provision of the Plan which is inconsistent with Section 423 or any successor provision of the Code shall without further act or amendment by the Company be reformed to comply with the requirements of Section 423. This Section 17 shall take precedence over all other provisions in the Plan. 6

18. Rights as Stockholders A Participant will have no rights as a stockholder under the election to purchase until he becomes a stockholder as herein provided. A Participant will become a stockholder with respect to shares for which payment has been completed as provided in Section 9 at the close of business on the last business day of the Purchase Period. 19. Modification and Termination The Board may amend or terminate the Plan at any time insofar as permitted by law. No amendment shall be effective unless within one year of the time it is adopted by the Board it is approved by the holders of a majority of outstanding shares of Common Stock, if and to the extent such amendment is required to be approved by stockholders in order to cause the rights granted under the Plan to purchase shares of Common Stock to meet the requirements of Section 423 of the Code (or any successor provision). The Plan shall terminate after all Common Stock issued under the Plan has been purchased, unless terminated earlier by the Board or unless additional Common Stock is issued under the Plan with the approval of the stockholders. In the event the Plan is terminated, the Committee may elect to terminate all outstanding rights to purchase shares under the Plan either immediately or upon completion of the purchase of shares on the next Purchase Date, unless the Committee has designated that the right to make all such purchases shall expire on some other designated date occurring prior to the next Purchase Date. If the rights to purchase shares under the Plan are terminated prior to expiration, all funds contributed to the Plan which have not been used to purchase shares shall be returned to the Participants as soon as administratively practicable. 20. Board and Shareholder Approval; Effective Date This Plan was adopted by the Board on September 11, 1998, and was previously amended by the Board on March 12, 1999, to be effective as of the Effective Date. The plan is further amended, effective January 1, 2001, by action of the Board on December 15, 2000, to increase the number of shares authorized to be issued hereunder. Notwithstanding the foregoing, the amendent of the Plan is expressly conditioned upon the approval by the holders of a majority of outstanding shares of Common Stock within 12 months of the date of Board approval of such amendment. If the stockholders of the Company should fail so to approve this Plan as amended, this Plan shall terminate and cease to be of any further force or effect and all purchases of shares of Common Stock under the Plan after December 31, 2000, shall be null and void. 21. Governmental Approvals or Consents This Plan and any offering or sale made to Employees under it are subject to any governmental approvals or consents that may be or become applicable in connection therewith. Subject to the provisions of Section 19, the Board may make such changes in the Plan and include such terms in any offering under the Plan as may be desirable to comply with the rules or regulations of any governmental authority. 22. Listing of Shares and Related Matters If at any time the Board or the Committee shall determine, based on opinion of legal counsel, that the listing, registration or qualification of the shares covered by the Plan upon any national securities exchange or reporting system or under any state or Federal law is necessary or desirable as a condition of, or in connection with, the sale or purchase of shares under the Plan, no shares will be sold, issued or delivered unless and until such listing, registration or qualification shall have been effected or obtained, or otherwise provided for, free of any conditions not acceptable to legal counsel. 23. Employment Rights The Plan shall neither impose any obligation on the Company to continue the employment of any Participant, nor impose any obligation on any Participant to remain in the employ of the Company. 7

24. Withholding of Taxes The Committee may make such provisions as it may deem appropriate for the withholding of any taxes which it determines is required in connection with the purchase of Common Stock under the Plan. 25. Governing Law The Plan and rights to purchase shares that may be granted hereunder shall be governed by and construed and enforced in accordance with the laws of the state of Delaware. 26. Use of Gender The gender of words used in the Plan shall be construed to include whichever may be appropriate under any particular circumstances of the masculine, feminine or neuter genders. 27. Other Provisions The agreements to purchase shares of Common Stock under the Plan shall contain such other provisions as the Committee and the Board shall deem advisable, provided that no such provision shall in any way be in conflict with the terms of the Plan. 8
