PROXY STATEMENT


ANNUAL MEETING OF STOCKHOLDERS
Friday, February 3, 2006


        Our annual meeting of stockholders will be held on Friday, February 3, 2006 at the Garden City Hotel at 10:00 a.m. Our Board of Directors is soliciting your proxy to vote your shares of common stock at the annual meeting. This proxy statement, which was prepared by our management for the Board of Directors, contains information about the matters to be considered at the meeting or any adjournments or postponements of the meeting and is first being sent to stockholders on or about December 28, 2005.


ABOUT THE MEETING

What is being considered at the meeting?

        You will be voting for

        We do not expect you to vote on any other matters at the meeting.

        In addition, our management will report on our performance during fiscal 2005 and respond to your questions.

Who is entitled to vote at the meeting?

        You may vote if you owned stock as of the close of business on December 23, 2005. Each share of stock is entitled to one vote.

How do I vote?

        You can vote in two ways:

Can I change my mind after I return my proxy?

        Yes, you may change your mind at any time before the vote is taken at the meeting. You can do this by (1) properly completing another proxy with a later date and returning it to us prior to the meeting or filing with our corporate secretary a written notice revoking your proxy or (2) voting again at the meeting.

What if I return my proxy card but do not include voting instructions?

        Proxies that are signed and returned but do not include voting instructions will be voted FOR the election of the nominee directors, FOR the approval of our 2006 Equity Incentive Plan and FOR the approval of our 2006 Performance Bonus Plan.

What does it mean if I receive more than one proxy card?

        It means that you have multiple accounts with brokers and/or our transfer agent. Please vote all of these shares. We recommend that you contact your broker and/or our transfer agent to consolidate as many accounts as possible under the same name and address. Our transfer agent is American Stock Transfer & Trust Company and their telephone number is (212) 936-5100.

Will my shares be voted if I do not provide my proxy?

        If you hold your shares directly in your own name, they will not be voted if you do not provide a proxy.

        Your shares may be voted under certain circumstances if they are held in the name of a brokerage firm. Brokerage firms generally have the authority to vote customers' unvoted shares on certain "routine" matters, including the election of directors. At our meeting these shares will be counted as voted by the brokerage firm in the election of directors.

        Brokers are prohibited from exercising discretionary authority on non-routine matters, such as Proposals 2 and 3, for beneficial owners who have not returned proxies to the brokers (so-called "broker non-votes"). In the case of broker votes, broker non-votes, and in cases where you abstain from voting on a matter when present at the meeting and entitled to vote, those shares will be counted for purposes of determining if a quorum is present.

How many votes must be present to hold the meeting?

        Your shares are counted as present at the meeting if you attend the meeting and vote in person or if you properly return a proxy by mail. In order for us to conduct our meeting, a majority of our outstanding shares of common stock as of December 23, 2005 must be present at the meeting. This is referred to as a quorum. On December 23, 2005, there were 29,941,724 shares of common stock outstanding and entitled to vote.

What vote is required to elect directors?

        Directors are elected by a plurality of the votes cast. Shares not voted will have no effect on the vote for election of directors.

2


What vote is required to approve our 2006 Equity Incentive Plan?

        The affirmative vote of the holders of a majority of the shares present in person or by proxy and entitled to vote on the item will be required for approval. An abstention will be counted as a vote against this proposal and broker non-votes will have no effect on the vote.

What vote is required to approve our 2006 Performance Bonus Plan?

        The affirmative vote of the holders of a majority of the shares present in person or by proxy and entitled to vote on the item will be required for approval. An abstention will be counted as a vote against this proposal and broker non-votes will have no effect on the vote.

PROPOSAL 2 — APPROVAL OF THE GRIFFON CORPORATION
2006 EQUITY INCENTIVE PLAN

General

        The Board of Directors has adopted and recommends that the stockholders approve the Griffon Corporation 2006 Equity Incentive Plan (the "Incentive Plan"). The general purpose of the Incentive Plan is to attract and retain selected employees, directors and consultants and provide them with incentives and rewards for superior performance.

Summary of the Plan

        The following general description of certain features of the Incentive Plan is qualified in its entirety by reference to the Incentive Plan, a copy of which is attached as Exhibit B to this Proxy Statement. Capitalized terms not otherwise defined in this summary have the meanings given to them in the Incentive Plan.

        General.    The Incentive Plan will authorize the grant of Performance Shares, Performance Units, Options, Stock Appreciation Rights, Restricted Shares and Deferred Shares (collectively called "Awards"). Options granted under the Incentive Plan may be either "incentive stock options," as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or nonqualified stock options, as determined by the Compensation Committee (the "Committee").

        Number of Shares Authorized.    The number of shares of our common stock initially available for award under the Incentive Plan is 1,700,000 shares (600,000 of which may be issued as incentive stock options). The Incentive Plan provides that the number of shares available for issuance is reduced by a factor of two to one for each share issued pursuant to an Award other than an Option. Accordingly, if the Compensation Committee grants all Awards under the Incentive Plan in the form of Restricted or Deferred Shares, for example, the maximum number of shares that may be issued is 850,000. The last sales price of our common stock as reported on the New York Stock Exchange for December 21, 2005 was $24.02 per share.

        If any Award is forfeited, or if any Option terminates, expires or lapses without being exercised, shares of our common stock subject to such Award will again be available for future grant. In addition, any shares under the Incentive Plan that are used to satisfy award obligations under the plan of another entity that is acquired by our company will not count against the remaining number of shares available. Finally, if there is any change in our corporate capitalization, the Committee may cancel and make substitutions of Awards or may adjust the number of shares available for award under the Incentive Plan, the number and kind of shares covered by Awards then outstanding under the Incentive Plan and the exercise price of outstanding Options and Stock Appreciation Rights.

10


        Administration.    The Committee will administer the Incentive Plan. Subject to the other provisions of the Incentive Plan, the Committee has the authority to:


        The Committee may also delegate to one or more officers of our company the authority to grant Awards to participants who are not subject to Section 16 of the Exchange Act or Section 162(m) of the Code.

        Eligibility.    The Incentive Plan provides that Awards may be granted to employees, non-employee directors and consultants of our company or its subsidiaries. Incentive stock options may be granted only to employees. The maximum number of shares that may be awarded to a participant in any fiscal year shall not in the aggregate exceed 500,000 with respect to Option Awards or 250,000 with respect to any Award other than an Option.

        Each Award granted under the Incentive Plan will be evidenced by a written award agreement between the participant and our company, which will describe the Award and state the terms and conditions to which the Award is subject. The principal terms and conditions of each particular type of Award are described below.

    Performance Awards

        Awards of Performance Shares and Performance Units may be made under the Incentive Plan. A Performance Share is a book-entry unit with a value equal to one share of common stock. A Performance Unit is a book-entry unit with a value equal to $1.00. A grant of Performance Shares or Performance Units will vest and become payable to the participant upon the achievement during a specified performance period of performance objectives established by the Committee. Except in the case of Qualified Performance-Based Awards, the Committee may modify performance objectives in whole or in part, during the performance period, as it deems appropriate and equitable.

        Performance objectives may be established on a company-wide basis; with respect to one or more subsidiaries, business units, divisions, department or functions; and in either absolute terms or relative to the performance of one or more comparable companies or an index covering multiple companies. Performance objectives, the number of units to which they pertain and the time and manner of payment of the Award, shall be specified in the Award agreement. Payment of Performance Shares and Performance Units will be made in shares of common stock.

11


        In the case of Qualified Performance-Based Awards, the applicable performance objectives are limited to one or more of the following:

12

        The Committee may also condition the grant and vesting or exercise of Options, Stock Appreciation Rights, Restricted Shares and Deferred Shares on the achievement of performance objectives as described above.

    Options

        An Option is the right to purchase shares of common stock for a specified period of time at a fixed price (the "exercise price"). Each Option agreement will specify the exercise price, the type of Option, the term of the Option, the date when the Option will become exercisable and any applicable performance goals.

        Exercise Price.    The Committee will determine the exercise price of an Option at the time the Option is granted. The exercise price under an incentive stock option or nonqualified stock option will not be less than 100% of the fair market value of common stock on the date the Option is granted. However, any optionee who owns more than 10% of the combined voting power of all classes of our company's outstanding common stock (a "10% Stockholder") will not be eligible for the grant of an incentive stock option unless the exercise price of the incentive stock option is at least 110% of the fair market value of the common stock on the date of grant.

        Consideration.    The means of payment for shares issued upon exercise of an Option will be specified in each Option agreement and generally may be made by cash or check, or subject to approval by the Committee, by certain other shares of common stock owned by the optionee for at least six months (including Restricted Shares), or by deferred payment through a broker or bank from the proceeds of the sale of the shares purchased through the exercise of the Option, or by any combination of the foregoing methods. If an Option is exercised with Restricted Shares that have not yet vested, the shares received upon exercise of the Option will, unless otherwise determined by the Committee, be subject to the same restrictions as the Restricted Shares.

        Term of the Option.    The term of an Option granted under the Incentive Plan will be no longer than ten years from the date of grant. In the case of an Option granted to a 10% Stockholder, the term of an incentive stock option will be for no more than five years from the date of grant.

    Stock Appreciation Rights

        A stock appreciation right ("SAR") entitles the recipient to receive, upon exercise of the SAR, the increase in the fair market value of a specified number of shares of common stock from the date of the grant of the SAR and the date of exercise payable in shares of common stock. Any grant may specify a waiting period or periods before the SAR may become exercisable and permissible dates or periods on or during which the SAR shall be exercisable, and may specify that the SAR may be exercised only in the event of a change of control of our company or similar event. No SAR may be exercised more than ten years from the grant date. The Committee may provide that an SAR is deemed to be exercised at the close of business on the date the SAR expires if such an exercise would result in a payment to the SAR holder.

    Restricted and Deferred Shares

        An Award of Restricted Shares is a grant to the recipient of a specified number of shares of common stock which are subject to forfeiture upon specified events during the restriction period. Each grant of Restricted Shares will specify the length of the restriction period and will include restrictions on transfer to third parties during the restriction period.

        An Award of Deferred Shares is an agreement by our company to deliver to the recipient a specified number of shares of common stock at the end of a specified deferral period, subject to the fulfillment of conditions specified by the Committee.

    General Provisions

        Vesting.    Each grant of Performance Shares and Performance Units will specify the performance objectives that must be achieved in order for payment to be made. Each grant of Options or SARs shall specify the length of service and/or any applicable performance goals that must be achieved before it becomes exercisable. Each grant of Restricted Shares shall specify the duration of the restriction period and any other conditions that under which the Restricted Shares would be forfeitable to our company, including any applicable performance goals. Each grant of Deferred Shares shall specify the deferral period and any other conditions to which future delivery of shares to the recipient is subject, including any applicable performance goals. Each grant may provide for the early exercise of rights or termination of a restriction or deferral period in the event of a Change in Control or similar transaction or event.

        Dividends/Ownership Rights.    Unless otherwise provided by the Committee, an Award of Restricted Shares entitles the participant to dividend, voting and other ownership rights during the restriction period. An Award of Deferred Shares does not entitle the participant to any transfer, voting or any other ownership rights with respect to the Deferred Shares.

        Nontransferability of Awards.    In general, during a participant's lifetime, his or her Awards shall be exercisable only by the participant and shall not be transferable other than by will or laws of descent and distribution. However, the Committee may provide for limited lifetime transfers of Awards, other than incentive stock options, to certain family members. In addition, an Award grant may provide for additional transfer restrictions on vested shares received upon exercise delivery or payment of an Award, including restrictions relating to minimum share ownership requirements applicable to any participant.

        Termination of Employment or Consulting Services.    The Committee may take actions which it believes equitable under the circumstances or in the best interest of our company with respect to Awards that are not fully vested in the event of termination of employment by reason of death, disability, normal retirement, early retirement with the consent of the Committee, other termination or a leave of absence that is approved by the Committee, or in the event of hardship or other special circumstances that are approved by the Committee. Unless otherwise determined by the Committee, a participant who is terminated for "Cause" (as defined in an applicable employment/consulting or severance agreement or Award agreement, or if no such agreement applies or contains such term, as determined by the Committee) shall forfeit all unexercised, unearned, and/or unpaid Awards, including vested Awards.

14


        Award Deferrals.    An Award Agreement may provide for the deferral of any Award or dividend until a time established by the Committee. Deferrals shall be accomplished by the delivery of a written, irrevocable election by the participant on a form provided by our company. Deferred Awards may also be credited with interest at rates determined by the Committee.

    Change in Control

        Unless otherwise determined by the Committee prior to the date of a Change in Control, in the event of a Change in Control, all Awards other than Options and SARS shall become non-forfeitable, and converted to shares of our common stock where applicable, and any unexercised Option or SAR shall become fully exercisable. Alternatively, the Committee may cancel and cash out outstanding Awards or arrange for the substitution of outstanding Awards with fully vested new awards of equal value. If a Change of Control occurs during one or more performance periods for which the Committee has not yet made a determination as to whether the applicable performance objectives were met, the performance period shall immediately terminate and it shall be assumed that the applicable performance objectives have been attained at a level of one hundred percent (100%). A participant shall be considered to have earned, and therefore be entitled to receive, payment of a prorated portion of the performance Awards that he or she would have received for the whole performance period, based on the portion of the performance period completed before the Change in Control.

        A "Change in Control" is defined in the Incentive Plan as:

15

        Effective Date, Amendments, and Termination of the Incentive Plan.    The Incentive Plan will be effective upon its approval by our company's stockholders. The Board of Directors has the authority to amend or terminate the Incentive Plan at any time; provided, however, that stockholder approval is required for any amendment, which (i) increases the number of shares available for Awards under the Incentive Plan (other than to reflect a change in our company's capital structure), ii) increases the maximum number of shares allowed for grants to any participant, (iii) changes the class of persons eligible to receive grants of Awards or the types of Awards available under the Incentive Plan, (iv) increases the benefits to participants under the Incentive Plan, or (v) as otherwise required by applicable law or under the rules of any applicable exchange. Further, no Award may be repriced, replaced, regranted through cancellation, or modified without stockholder approval. Finally, the Incentive Plan will terminate automatically ten years after it is approved by stockholders.

Certain Federal Income Tax Considerations

        The following discussion is a summary of certain federal income tax considerations that may be relevant to participants in the Incentive Plan. The discussion is for general informational purposes only and does not purport to address specific federal income tax considerations that may apply to a participant based on his or her particular circumstances, nor does it address state or local income tax or other tax considerations that may be relevant to a participant.

        PARTICIPANTS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR FEDERAL INCOME TAX CONSEQUENCES TO THEM OF PARTICIPATING IN THE INCENTIVE PLAN, AS WELL AS WITH RESPECT TO ANY APPLICABLE STATE OR LOCAL INCOME TAX OR OTHER TAX CONSIDERATIONS.

        Performance Units and Performance Shares.    A participant realizes no taxable income and our company is not entitled to a deduction when Performance Units or Performance Shares are awarded. When the Performance Units or Performance Shares vest and become payable upon the achievement of the performance objectives, the participant will realize ordinary income equal to the fair market value of the shares received minus any amount paid for the shares, and, subject to Section 162(m) of the Code, our company will be entitled to a corresponding deduction. A participant's tax basis in shares of common stock received upon payment will be equal to the fair market value of such shares when the participant receives them. Upon sale of the shares, the participant will realize short-term or long-term capital gain or loss, depending upon whether the shares have been held for more than one year at the time of sale. Such gain

16


or loss will be equal to the difference between the amount realized upon the sale of the shares and the tax basis of the shares in the participant's hands.

        Deferred Shares.    A participant realizes no taxable income and our company is not entitled to a deduction when Deferred Shares are awarded. When the deferral period for the award ends and the participant receives shares of common stock, the participant will realize ordinary income equal to the fair market value of the shares at that time, and, subject to Section 162(m) of the Code, our company will be entitled to a corresponding deduction. A participant's tax basis in shares of our common stock received at the end of a deferral period will be equal to the fair market value of such shares when the participant receives them. Upon sale of the shares, the participant will realize short-term or long-term capital gain or loss, depending upon whether the shares have been held for more than one year at the time of sale. Such gain or loss will be equal to the difference between the amount realized upon the sale of the shares and the tax basis of the shares in the participant's hands.

Restricted Shares

        Restricted Shares received pursuant to awards will be considered subject to a substantial risk of forfeiture for federal income tax purposes. If a participant who receives such Restricted Shares does not make the election described below, the participant realizes no taxable income upon the receipt of Restricted Shares and our company is not entitled to a deduction at such time. When the forfeiture restrictions with respect to the Restricted Shares lapse the participant will realize ordinary income equal to the fair market value of the shares at that time, and, subject to Section 162(m) of the Code, our company will be entitled to a corresponding deduction. A participant's tax basis in Restricted Shares will be equal to their fair market value when the forfeiture restrictions lapse, and the participant's holding period for the shares will begin when the forfeiture restrictions lapse. Upon sale of the shares, the participant will realize short-term or long-term gain or loss, depending upon whether the shares have been held for more than one year at the time of sale. Such gain or loss will be equal to the difference between the amount realized upon the sale of the shares and the tax basis of the shares in the participant's hands.

        Participants receiving Restricted Shares may make an election under Section 83(b) of the Code with respect to the shares. By making a Section 83(b) election, the participant elects to realize compensation income with respect to the shares when the shares are received rather than at the time the forfeiture restrictions lapse. The amount of such compensation income will be equal to the fair market value of the shares when the participant receives them (valued without taking the restrictions into account), and our company will be entitled to a corresponding deduction at that time. By making a Section 83(b) election, the participant will realize no additional compensation income with respect to the shares when the forfeiture restrictions lapse, and will instead recognize gain or loss with respect to the shares when they are sold. The participant's tax basis in the shares with respect to which a Section 83(b) election is made will be equal to their fair market value when received by the participant, and the participant's holding period for such shares begins at that time. If, however, the shares are subsequently forfeited to our company, the participant will not be entitled to claim a loss with respect to the shares to the extent of the income realized by the participant upon the making of the Section 83(b) election. To make a Section 83(b) election, a participant must file an appropriate form of election with the Internal Revenue Service and with his or her employer, each within 30 days after shares of restricted stock are received, and the participant must also

17


attach a copy of his or her election to his or her federal income tax return for the year in which the shares are received.

        Generally, during the restriction period, dividends and distributions paid with respect to restricted stock will be treated as compensation income (not dividend income) received by the participant. Dividend payments received with respect to shares of restricted stock for which a Section 83(b) election has been made will be treated as dividend income, assuming our company has adequate current or accumulated earnings and profits.

    Nonqualified Options

        A participant realizes no taxable income and our company is not entitled to a deduction when a non-qualified option is granted. Upon exercise of a nonqualified option, a participant will realize ordinary income equal to the excess of the fair market value of the shares received over the exercise price of the non-qualified option, and, subject to Section 162(m) of the Code, our company will be entitled to a corresponding deduction. A participant's tax basis in the shares of common stock received upon exercise of a nonqualified option will be equal to the fair market value of such shares on the exercise date, and the participant's holding period for such shares will begin at that time. Upon sale of the shares of common stock received upon exercise of a non-qualified option, the participant will realize short-term or long-term capital gain or loss, depending upon whether the shares have been held for more than one year. The amount of such gain or loss will be equal to the difference between the amount realized in connection with the sale of the shares, and the participant's tax basis in such shares.

        Under the Incentive Plan, non-qualified options may, at the option of the Committee, be exercised in whole or in part with shares of common stock or Restricted Shares held by the participant. Payment in common stock or Restricted Shares will be treated as a tax-free exchange of the shares surrendered for an equivalent number of shares of common stock received, and the equivalent number of shares received will have a tax basis equal to the tax basis of the surrendered shares. In the case of payment in Restricted Shares, however, the equivalent number of shares of common stock received shall be subject to the same risks of forfeiture or restrictions on transfer as those that applied to the Restricted Shares surrendered. The fair market value of shares of common stock received in excess of the number of shares surrendered will be treated as ordinary income and such shares have a tax basis equal to their fair market value on the date of the exercise of the nonqualified option.

Incentive Stock Options

        A participant realizes no taxable income and our company is not entitled to a deduction when an incentive stock option is granted or exercised. Provided the participant meets the applicable holding period requirements for the shares received upon exercise of an incentive stock option (two years from the date of grant and one year from the date of exercise), gain or loss realized by a participant upon sale of the shares received upon exercise will be long-term capital gain or loss, and our company will not be entitled to a deduction. If, however, the participant disposes of the shares before meeting the applicable holding period requirements (a "disqualifying disposition"), the participant will realize ordinary income at that time equal to the excess of the fair market value of the shares on the exercise date over the exercise price of the incentive stock option. Any amount realized upon a disqualifying disposition in excess of the fair market

18


value of the shares on the exercise date of the incentive stock option will be treated as capital gain and will be treated as long-term capital gain if the shares have been held for more than one year. If the sales price is less than the sum of the exercise price of the incentive stock option and the amount included in ordinary income due to the disqualifying disposition, this amount will be treated as a short-term or long-term capital loss, depending upon whether the shares have been held for more than one year. Notwithstanding the above, individuals who are subject to Alternative Minimum Tax may recognize ordinary income upon exercise of an incentive stock option.

        Under the Incentive Plan, incentive stock options may, at the option of the Committee, be exercised in whole or in part with shares of common stock or Restricted Shares held by the participant. Such an exercise will be treated as a tax-free exchange of the shares of common stock or Restricted Shares surrendered (assuming the surrender of the previously-owned shares does not constitute a disqualifying disposition of those shares) for an equivalent number of shares of common stock received, and the equivalent number of shares received will have a tax basis equal to the tax basis of the surrendered shares. In the case of payment in Restricted Shares, however, the equivalent number of shares of common stock received shall be subject to the same risks of forfeiture or restrictions on transfer as those that applied to the Restricted Shares surrendered. Shares of common stock received in excess of the number of shares surrendered will have a tax basis of zero.

    SARs

        A participant realizes no taxable income and our company is not entitled to a deduction when a SAR is granted. Upon exercising a SAR, a participant will realize ordinary income in an amount equal to the fair market value of the shares received minus any amount paid for the shares, and, subject to Section 162(m) of the Code, our company will be entitled to a corresponding deduction. A participant's tax basis in the shares of common stock received upon exercise of a SAR will be equal to the fair market value of such shares on the exercise date, and the participant's holding period for such shares will begin at that time. Upon sale of the shares of common stock received upon exercise of a SAR, the participant will realize short-term or long-term capital gain or loss, depending upon whether the shares have been held for more than one year. The amount of such gain or loss will be equal to the difference between the amount realized in connection with the sale of the shares, and the participant's tax basis in such shares.

Section 162(m) Limitations

        Section 162(m) of the Code limits the deductibility of compensation paid to certain executive officers, unless the compensation is "performance-based compensation" and meets certain other requirements outlined in Code Section 162(m) and related regulations ("Qualified Performance-Based Awards"). If Awards to such persons are intended to qualify as Qualified Performance-Based Awards, the Incentive Plan requires that the maximum performance-based Award that may be granted to the recipient during any one performance period is 250,000 shares of common stock.

Withholding

        Our company is entitled to deduct from the payment of any Award all applicable income and employment taxes required by federal, state, local or foreign law to be withheld, or may require the

19


participant to pay such withholding taxes to our company as a condition of receiving payment of the Award. The Committee may allow a participant to satisfy his or her withholding obligations by directing our company to retain the number of shares necessary to satisfy the withholding obligation, or by delivering shares held by the participant to our company in an amount necessary to satisfy the withholding obligation.

New Plan Benefits

        There have been no grants under the Incentive Plan. Because benefits under the Incentive Plan will depend on the actions of the Committee and the value of our company's common stock, it is not possible to determine the benefits that will be received if stockholders approve the Incentive Plan.

Vote Required and the Recommendation of the Board

        To be adopted, the Incentive Plan requires the affirmative vote of a majority of the votes cast by all stockholders entitled to vote thereon.

OUR BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO APPROVE THE 2006 EQUITY INCENTIVE PLAN.

20


PROPOSAL 3 — APPROVAL OF THE GRIFFON CORPORATION
2006 PERFORMANCE BONUS PLAN

General

        The Board of Directors has adopted and recommends that the stockholders approve the Griffon Corporation 2006 Performance Bonus Plan (the "Performance Bonus Plan"). The general purpose of the Performance Bonus Plan is to benefit and advance our interests by rewarding selected employees of our company and its subsidiaries and divisions (each such subsidiary or division is referred to herein as a "Business Unit") for their contributions to our company's financial success and thereby motivate the employees to continue to make such contributions to our company in the future by granting performance-based awards that are fully tax deductible to our company.

Summary of the Plan

        The following general description of certain features of the Performance Bonus Plan is qualified in its entirety by reference to the Performance Bonus Plan, a copy of which is attached as Exhibit C to this Proxy Statement. Capitalized terms not otherwise defined in this summary have the meanings given to them in the Performance Bonus Plan. The Performance Bonus Plan will permit incentive compensation bonus awards to be structured to qualify as "performance-based" compensation under Section 162(m) of the Code.

Background

        Section 162(m) of the Code disallows a deduction to our company for any compensation paid to a "Covered Employee" in excess of $1 million per year, subject to certain exceptions. In general, "Covered Employees" include the chief executive officer and the four most highly compensated executive officers of our company who are in the employ of our company and are officers at the end of the tax year. Among other exceptions, the deduction limit does not apply to compensation that meets the specified requirements for "performance-based compensation." In general, those requirements include the establishment of objective performance goals for the payment of such compensation by a committee of the Board of Directors composed solely of two or more outside directors, stockholder approval of the material terms of such compensation prior to payment, and certification by the Compensation Committee (the "Committee") that the performance goals for the payment of such compensation have been achieved.

        The Board of Directors believes that it is in the best interests of our company and its stockholders to enhance the ability of our company to attract and retain qualified personnel by providing annual and long-term incentive compensation bonus awards to employees generally, as well as to certain officers that would qualify as "performance-based compensation" under Section 162(m) of the Code, while at the same time obtaining the highest level of deductibility of compensation paid to employees.

Description of the Performance Bonus Plan

        The Performance Bonus Plan will be administered by the Committee. The Committee has the authority to administer interpret and apply the Performance Bonus Plan, including the authority to select the employees (including employees who are directors) to participate in the Performance Bonus Plan, to

21


establish the performance goals, to determine the amount of incentive compensation bonus payable to any participant, and to make all determinations and take all other actions necessary or appropriate for proper administration and operation of the Performance Bonus Plan.

        Administration.    The Committee will administer the Performance Bonus Plan. Subject to the other provisions of the Performance Bonus Plan, the Committee has the authority to:

        The Committee may also delegate to one or more executive officers of our company the authority to administer the Performance Bonus Plan with respect to any participants who are not Covered Employees. The Committee may also, at any time and from time to time, alter, amend, suspend or terminate the Performance Bonus Plan in whole or in part. However, no such amendment shall be effective which alters any grant, performance target or other criteria relating to any grant to a Covered Employee for the performance period in which such amendment is made or any prior performance period, except as such amendment may be made without causing such grant to cease to qualify as performance-based compensation under Section 162(m) of the Code.

        Eligibility.    All employees of our company are eligible to participate in the Performance Bonus Plan. The maximum amount of the incentive compensation bonuses payable to any participant under the Performance Bonus Plan in, or in respect of, any single fiscal year shall not exceed $5 million. All incentive compensation bonuses paid pursuant to the Performance Bonus Plan will be paid in cash.

        Bonus Opportunity and Performance Goals.    Bonuses may be payable to a participant as a result of the satisfaction of performance goals in respect of any performance period determined by the Committee. With respect to Covered Employees, prior to the beginning of a performance period or any later date described in Treasury Regulation 1.162-27(e)(2), the Committee will establish a target bonus opportunity or range of bonus opportunities for each participant based upon the attainment of one or more performance goals established by the Committee at such time. With respect to participants who are not Covered Employees, such bonus opportunities and performance goals shall be established prior to the end of any performance period. Performance goals, which may vary among and between participants and incentive compensation bonus opportunities, are limited to one or more of the following:

22


        The Committee shall provide a threshold level of performance below which no incentive compensation bonus will be paid, as well as a maximum level of performance above which no additional incentive compensation bonus will be paid. It also may provide for the payment of differing amounts for different levels of performance, determined with regard either to a fixed monetary amount or a percentage of the participant's base salary. The Committee shall make such adjustments, to the extent it deems appropriate, to established performance goals and performance thresholds to compensate for, or to reflect,

23

any material changes which may have occurred due to an "Extraordinary Event" (as defined under the Performance Bonus Plan).

        As soon as practicable after the end of each performance period, but before any incentive compensation bonuses are paid to the participants under the Performance Bonus Plan, the Committee (subject to any necessary verification) will certify in writing (i) whether the performance goal(s) were attained and (ii) the amount of the incentive compensation bonus payable to each participant based upon the attainment of such specified performance goals. The Committee also may reduce, eliminate, or, with respect only to participants who are not Covered Employees, increase the amount of any incentive compensation bonus of any participant at any time prior to payment thereof, based on such criteria as the Committee shall determine, including but not limited to individual merit and attainment of, or the failure to attain, specified personal goals established by the Committee. Under no circumstances, however, may the Committee, with respect solely to a participant who is a Covered Employee, (a) increase the amount of the incentive compensation otherwise payable to such participant beyond the amount originally established by the Committee, (b) waive the attainment of the performance goals established and applicable to such participant's incentive compensation or (c) otherwise exercise its discretion so as to cause any incentive compensation bonus payable to such participant to not qualify as "performance-based compensation" under Section 162(m) of the Code.

        All amounts due under the Performance Bonus Plan shall be paid within 21/2 months of the end of the year in which such incentive compensation is no longer subject to a risk of forfeiture.

        The Board of Directors, without the consent of any participant, may amend or terminate the Performance Bonus Plan at any time. However, no amendment that would require the consent of the stockholders pursuant to Section 162(m) of the Code shall be effective without such consent.

        Effective Date.    The Performance Bonus Plan shall be effective as of December 6, 2005 (the date the Board approved the Plan); provided, however, that the Performance Bonus Plan and any grants under the plan shall be conditioned upon stockholder approval. Accordingly, if stockholder approval is not obtained, the Performance Bonus Plan and any grant issued thereunder shall not be effective.

Vote Required and the Recommendation of the Board

        To be adopted, the Performance Bonus Plan requires the affirmative vote of a majority of the votes cast by all stockholders entitled to vote thereon.

OUR BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO APPROVE THE 2006 PERFORMANCE BONUS PLAN.

Employment Agreements

        In May 2001, we entered into an amended and restated employment agreement with Harvey R. Blau. In July 2003, the agreement was amended to extend its term until December 1, 2009. Pursuant to the agreement, Mr. Blau receives a base salary and an annual bonus calculated in accordance with our Senior Management Incentive Compensation Plan.

        The employment agreement further provides for a five year consulting period after the termination of employment during which Mr. Blau will receive consulting payments in an annual amount equal to two-thirds of his last annual base salary, subject to cost of living increases. The employment agreement also provides for cost of living adjustments, life insurance and medical care reimbursement for the executive and his spouse. In addition, the employment agreement provides, following the disability of the executive, for lifetime medical insurance for the executive and his spouse and, following the death of the executive, for such insurance for his spouse.

        The employment agreement further provides that in the event there is a change in the control of the company, as defined therein, Mr. Blau has the option, exercisable within one year after such event, to terminate his employment agreement. Upon such termination, he has the right to receive as a lump sum payment the compensation (including incentive bonus, if any) remaining to be paid for the balance of the term of the agreement. In addition, we will provide the executive with a tax gross-up payment to cover any excise tax due.

        In March 2005, we entered into an employment agreement with Eric P. Edelstein for a term ending March 1, 2008. The agreement provides for (i) a base salary of $500,000 per year and (ii) a bonus equal to the difference between 1% of the consolidated pretax earnings of the company and the base salary paid to Mr. Edelstein. The bonus for fiscal 2005 and for fiscal 2006 will be at a minimum annual rate of $350,000. In 2005, Mr. Edelstein received a bonus of $204,000 for the portion of the year during which he was employed by the company. Mr. Edelstein is entitled to receive severance payments upon the termination of his employment under certain circumstances.

        In order to induce Mr. Edelstein to enter into the employment agreement, we granted him an option to purchase 250,000 shares of our common stock at a price of $22.94 per share, the closing price of the common stock on March 1, 2005. The option has a seven year term and becomes exercisable as to 50% of the shares on March 1, 2006 and as to 100% of the shares on March 1, 2007.

        In February 2005, Robert Balemian retired from the position of Chief Financial Officer of the company and, in May 2005, Mr. Balemian resigned from the position of President of our company, as well as from our Board of Directors. In accordance with his employment agreement, Mr. Balemian received salary through the date of termination, a bonus for service through the date of termination in accordance with the company's Senior Management Incentive Compensation Plan and has commenced receiving the benefits provided under our Supplemental Executive Retirement Plan.

        Effective upon the end of his employment, and in accordance with his employment agreement, Mr. Balemian became a consultant to our company, which relationship continues for a period of five years. During this period, Mr. Balemian is obligated to consult with the senior executive officers regarding our businesses and operations. During this consultation period, Mr. Balemian receives as a consulting fee an amount equivalent to two-thirds of his salary at the end of his employment with our company, subject to cost of living increases, and is entitled to receive medical and certain other benefits to which he was entitled during his term of employment.

Stock and Compensation Plans

    Stock Option Plans

        We maintain various stock option plans, as set forth in the table below. The purchase price of the shares of common stock subject to each option granted is not less than 100% of the fair market value at the date of grant. The term of each option is generally ten years and is determined at the time of grant by the Board of Directors or its Compensation Committee. The participants in these plans are officers and employees of the company and its subsidiaries or affiliates, except that our 1998 Employee and Director Stock Option Plan may also include directors and consultants.

    Compensation Plans

        Senior Management Incentive Compensation Plan.    Our Senior Management Incentive Compensation Plan (the "Senior Management Plan"), which was adopted by the Board of Directors in November 1997 and approved by the stockholders in February 1998, provides for an annual bonus to Mr. Blau based upon company performance. Under the Senior Management Plan, Mr. Blau is entitled to receive a bonus based upon our consolidated pretax earnings, as defined, for each fiscal year. Mr. Blau's annual bonus equals 4% of the first $5,000,000 of consolidated pretax earnings, plus 5% of the amount of consolidated pretax earnings in excess of $5,000,000.

        Upon a Change in Control of the company (as defined in the Senior Management Plan), a bonus will be paid to Mr. Blau with respect to the portion of our then current fiscal year before the Change in Control, based upon performance for that portion of the year.

        Our Senior Management Plan provided an annual bonus to Mr. Balemian that equaled 2.5% of the first $3,000,000 of consolidated pretax earnings, plus 3.5% of the next $2,000,000 of consolidated pretax earnings, plus 5% of the amount of consolidated pretax earnings in excess of $5,000,000. Mr. Balemian's bonus for fiscal 2005 was determined by prorating, based upon the portion of the fiscal year that he was

30


employed, the annual bonus that he would have received based upon this formula had he been employed for the entire fiscal year.

        Outside Director Stock Award Plan.    We have an Outside Director Stock Award Plan (the "Outside Director Plan"), which was approved by stockholders in 1994, under which 330,000 shares of common stock may be issued to non-employee directors. Annually, at the time of each annual meeting of stockholders, each eligible director is awarded shares of our common stock having a value of $10,000, which shares vest in equal installments over a three-year period. During fiscal 2005, 4,246 shares of common stock were issued under the Outside Director Plan. As of November 30, 2005, an aggregate of 213,288 shares of common stock remained available for future grants under the Outside Director Plan.

        Employee Stock Ownership Plan.    In May 1983, we adopted an Employee Stock Ownership Plan, as amended ("ESOP"). Our employees and employees of our subsidiaries are eligible to participate in the Plan, provided they are not members of a collective bargaining unit. The ESOP has a Trustee, U.S. Trust Company, N.A. (the "Trustee"), who votes the securities held by the ESOP (other than securities of the company which have been allocated to employees' accounts).

        The annual contributions to the ESOP are to be in such amounts as the Board of Directors in its sole discretion shall determine. Historically, the Board of Directors has authorized contributions in an amount sufficient to satisfy the ESOP's obligations with respect to the loan agreement described below. Each employee who participates in the ESOP has a separate account and the annual contribution by us to an employee's account is not permitted to exceed the lesser of $40,000 (or such other limit as may be the maximum permissible pursuant to the provisions of Section 415 of the Internal Revenue Code and Regulations issued thereunder) or 100% of such employee's annual compensation, as defined under the ESOP. No contributions are required of, nor are any accepted from, any employee.

        Contributions to the ESOP are invested primarily in the company's securities. The Trustee has the right to purchase the company's securities on behalf of employees. The Trustee is considered the stockholder for the purpose of exercising all owners' and stockholders' rights with respect to the company's securities held in the ESOP, except for voting rights, which inure to the benefit of each participant who can vote all shares of common stock held in his account, even if said shares are not vested. As of November 30, 2005, there were 2,628,624 shares of common stock in the ESOP, of which 2,404,588 were allocated to employees and 224,036 were unallocated.

        The Trustee is empowered to borrow funds for the purpose of purchasing the company's securities. The securities so purchased are required to be held in an acquisition indebtedness account, to be released and made available for allocation as principal and interest are repaid. The ESOP has entered into a loan agreement, the proceeds of which were used to purchase our common stock. The loan is guaranteed by us and is being repaid in quarterly installments through 2011. As of November 30, 2005, the ESOP had outstanding borrowings of $2,500,000.

Supplemental Executive Retirement Plan

        Effective October 1, 1996, we adopted the Griffon Corporation Supplemental Executive Retirement Plan ("SERP") for certain of our officers.

        The normal retirement age under the SERP is 72. No benefit is payable unless a participant is vested at the time of termination of employment. A participant's right to receive a benefit vests after 20 years of service and one year of participation in the SERP, or upon a Change of Control (as defined in the SERP).

        The SERP provides an annual benefit upon termination equal to the sum of .25% of Average Base Salary and 1.5% of Average Bonus/Incentive Compensation multiplied by completed years of service (up to a maximum of 30). "Average" means the average of the three highest paid years out of the last ten prior to retirement. The benefit is reduced by any Social Security benefit attributable to the employment of the participant. Benefits are adjusted for early retirement and retirement after the normal retirement date. Retirement benefits are payable for life, with a guarantee of 10 years of payments. In addition, the SERP provides a pre-retirement death benefit payable for 10 years to the participant's beneficiary.

        The table below shows the projected annual benefits payable at age 72 under the SERP before the reduction for Social Security benefits. A participant's SERP benefit would be the total of the applicable amounts from each table, minus the Social Security benefit attributable to the participant's employment. The number of years of service of the participants as of November 30, 2005 are: Mr. Blau, 33 and Mr. Alesia, 32.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

General

        The compensation of our executive officers is generally determined by the Compensation Committee of the Board of Directors, subject to applicable employment agreements and incentive plans. Each member of the Compensation Committee is a director who is not employed by us or any of our affiliates. The following report with respect to certain compensation paid or awarded to our executive officers during fiscal 2005 is furnished by the directors who comprised the Compensation Committee during fiscal 2005.

General Compensation Philosophy

        Our compensation programs are intended to enable us to attract, motivate, reward and retain the management talent required to achieve corporate objectives, and thereby increase stockholder value. It is our policy to provide incentives to senior management to achieve both short-term and long-term objectives and to reward exceptional performance and contributions to the development of our businesses. To attain these objectives, our executive compensation program includes three key components:

Compensation Program Elements

        Base Salary.    The Compensation Committee annually establishes, subject to the approval of the Board of Directors and the terms of any applicable employment agreements, the salaries which will be paid to our executive officers during the coming year. In setting salaries, the Compensation Committee takes into account several factors, including competitive compensation data, the extent to which an individual may participate in the equity-based plans maintained by us, and qualitative factors bearing on an individual's experience, responsibilities, management and leadership abilities and job performance.

        Cash Incentive Bonuses.    Cash incentive bonuses are designed to provide a significant and variable economic opportunity to our executive officers. Our Senior Management Incentive Plan (the "Senior Management Plan") entitles our Chief Executive Officer, and entitled our former President and Chief Financial Officer, to receive a cash bonus equal to an incremental percentage of our consolidated pretax earnings. The bonus payable under our Senior Management Plan increases as the financial performance of our company improves.

        In December 2005, the Board of Directors of our company adopted the 2006 Performance Bonus Plan (the "Performance Bonus Plan"), which is being presented for stockholder approval at our Annual Meeting of Stockholders to be held on February 3, 2006. The Performance Bonus Plan is administered by the Compensation Committee, which selects the participants and establishes the performance periods and the specific performance goals to be achieved during those periods. Bonus awards are intended to qualify as "performance-based compensation" under Section 162(m) of the Internal Revenue Code. The Compensation Committee believes that the Performance Bonus Plan will enhance the ability of our

35


company to attract and retain employees, including executive officers, by providing performance-based incentives, while at the same time obtaining the highest level of deductibility of compensation paid to employees. It is not expected that either Harvey R. Blau, our Chairman and Chief Executive Officer, or Eric P. Edelstein, our Executive Vice President and Chief Financial Officer, will participate in the Performance Bonus Plan because, as described in this Report, each of them is already covered by other cash incentive bonus arrangements.

        Equity-based Compensation.    Historically, equity-based compensation consisted of stock options granted to employees, including our executive officers, by the Compensation Committee under our stock option plans. The Committee believes that stock options provide an incentive that focuses the executive's attention on managing our company from the perspective of an owner with an equity stake in the business. Options are awarded with an exercise price equal to the fair market value of common stock on the date of grant, have a maximum term of ten years and become exercisable according to the terms and conditions of vesting established at the discretion of the Compensation Committee. Among our executive officers, the number of shares of common stock subject to options granted to each individual generally depends upon the level of that officer's responsibility. The largest grants are generally awarded to the most senior officers who, in the view of the Compensation Committee, have the greatest potential impact on our profitability and growth. Previous grants of stock options are reviewed in determining the size of any executive's stock option award in a particular year.

        The Board of Directors of our company adopted, in December 2005, the 2006 Equity Incentive Plan (the "Incentive Plan"), which is being presented for stockholder approval at our upcoming Annual Meeting of Stockholders. The purpose of the Incentive Plan is to broaden the scope of our company's equity compensation programs by providing a variety of incentives that may be granted by the Compensation Committee, including, but not limited to, stock options, restricted stock, deferred shares and stock appreciation rights. The Compensation Committee believes that the Incentive Plan will allow our company to attract and retain executive management by providing them with appropriate equity-based incentives and rewards for superior performance.

        From time to time, the Compensation Committee utilizes the services of independent consultants to perform analyses and to make recommendations to the Committee relative to executive compensation matters. Based on these consultations, and upon the independent analysis of its members in light of our employment agreements with certain officers, the Compensation Committee recommends to our Board of Directors the appropriate compensation package for each executive officer.

Determining Executive Officer Compensation

        For fiscal 2005, pursuant to the terms of his employment agreement with us and the Senior Management Plan, Mr. Robert Balemian, our former President and Chief Financial Officer, received a base salary and an incentive bonus based on our consolidated pretax earnings. See "Management — Employment Agreements" and "Management — Senior Management Incentive Compensation Plan." Mr. Edelstein, our Executive Vice President and Chief Financial Officer, received a base salary, a bonus determined on the basis of the portion of the fiscal year that he was employed and a grant of stock options upon execution of his employment agreement. For fiscal 2006, Mr. Edelstein is entitled to receive a bonus equal to the difference between 1% of our consolidated pretax earnings and his

36


base salary, subject to a minimum bonus of $350,000. Mr. Patrick L. Alesia, our Vice President, Treasurer and Secretary, received a base salary, a cash bonus and a grant of stock options. The Compensation Committee determined that the base salary paid to Mr. Alesia, the bonus paid to Mr. Alesia and the grant of stock options to Mr. Alesia were appropriate given our financial performance, the substantial contributions made by him to such performance, his increased level of responsibilities and the compensation levels of executives at comparable companies. Future bonuses awarded to Mr. Alesia may be pursuant to the Performance Bonus Plan.

Compensation of Chief Executive Officer

        For fiscal 2005, pursuant to the terms of his employment agreement with us and the Senior Management Plan, Mr. Harvey R. Blau, our Chairman and Chief Executive Officer, received a base salary and an incentive bonus based on our consolidated pretax earnings. No stock options were granted to Mr. Blau during fiscal 2005. See "Management — Employment Agreements" and "Management — Senior Management Incentive Compensation Plan."

AUDIT COMMITTEE REPORT

        As required by its written charter, which sets forth its responsibilities and duties, a copy of which is attached as Exhibit A to this Proxy Statement, the Audit Committee reviewed and discussed our audited financial statements as of and for the year ended September 30, 2005 with management.

        The Audit Committee reviewed and discussed with representatives of PricewaterhouseCoopers LLP, our independent registered public accounting firm, the matters required to be discussed by Statement on Auditing Standards No. 61 (Codification of Statements on Auditing Standards, AU §380), as amended. The Audit Committee has also received and reviewed the written disclosures and the letter from PricewaterhouseCoopers LLP required by Independence Standard No. 1, "Independence Discussions with Audit Committees," as amended by the Independence Standards Board, and has discussed with PricewaterhouseCoopers LLP their independence.

        Based on these reviews and discussions, the Audit Committee recommended to the Board of Directors that the financial statements referred to above be included in our Annual Report on Form 10-K for the year ended September 30, 2005 for filing with the Securities and Exchange Commission.

        The Audit Committee has also reviewed and discussed the fees paid to PricewaterhouseCoopers LLP during the last fiscal year for audit and non-audit services, which are set forth below under "Audit and Related Fees" and has considered whether the provision of the non-audit services is compatible with maintaining PricewaterhouseCoopers LLP's independence and concluded that it is.

Audit Committee Financial Expert

        The Board has determined that Joseph J. Whalen, a member of the Audit Committee since 1999, qualifies as an "Audit Committee Financial Expert", as defined by Securities and Exchange Commission Rules, based on his education, experience and background.

MISCELLANEOUS INFORMATION

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Exchange Act, as amended, requires our executive officers, directors and persons who own more than ten percent of a registered class of our equity securities ("Reporting Persons") to file reports of ownership and changes in ownership on Forms 3, 4 and 5 with the Securities and Exchange Commission and the New York Stock Exchange. These Reporting Persons are required by SEC regulation to furnish us with copies of all Forms 3, 4 and 5 they file with the SEC and The New York Stock Exchange. Based solely upon our review of the copies of the forms we have received, we believe that all Reporting Persons complied on a timely basis with all filing requirements applicable to them with respect to transactions during fiscal 2005.

Matters to be Considered at the Meeting

        The Board of Directors does not intend to present to the meeting any matters not referred to in the form of proxy. If any proposal not set forth in this Proxy Statement should be presented for action at the meeting, and is a matter which should come before the meeting, it is intended that the shares represented by proxies will be voted with respect to such matters in accordance with the judgment of the persons voting them.

Cost of Solicitation

        The cost of soliciting proxies in the accompanying form, which we estimate to be $70,000, will be paid by us. In addition to solicitations by mail, arrangements may be made with brokerage houses and other custodians, nominees and fiduciaries to send proxy material to their principals, and we may reimburse them for their expenses in so doing. To the extent necessary in order to assure sufficient representation, our officers and regular employees may request the return of proxies personally, by telephone or telegram. The extent to which this will be necessary depends entirely upon how promptly proxies are received, and stockholders are urged to send in their proxies without delay.

Deadline for Submission of Stockholder Proposals for the 2007 Annual Meeting

        Proposals of stockholders intended to be presented at the 2007 Annual Meeting of Stockholders pursuant to SEC Rule 14a-8 must be received at our principal office not later than August 31, 2006 to be included in the proxy statement for that meeting.

        In addition, our by-laws require that we be given advance notice of stockholder nominations for election to the Board of Directors and of other matters which stockholders wish to present for action at an annual meeting of stockholders. The required notice must be delivered to the Secretary of the company at our principal offices not less than 90 days and not more than 120 days prior to the anniversary date of the

41


immediately preceding annual meeting of stockholders. These requirements are separate from and in addition to the SEC requirements that a stockholder must meet in order to have a stockholder proposal included in our proxy statement.

        Pursuant to our by-laws, if notice of any stockholder proposal is received after November 6, 2006, then the notice will be considered untimely and we are not required to present such proposal at the 2007 Annual Meeting. If the Board of Directors chooses to present a proposal submitted after November 6, 2006 at the 2007 Annual Meeting, then the persons named in proxies solicited by the Board of Directors for the 2007 Annual Meeting may exercise discretionary voting power with respect to such proposal.

        We will provide without charge to any stockholder as of the record date, copies of our Annual Report on Form 10-K, upon written request delivered to Patrick L. Alesia, Secretary, at our offices at 100 Jericho Quadrangle, Jericho, New York 11753.

Unless otherwise determined by the Committee, whenever any Option Price is paid in whole or in part by means of any of the forms of consideration specified in this Section 6.4, the Shares received by the Optionee upon the exercise of the Options shall be subject to the same risks of forfeiture or restrictions on transfer as those that applied to the consideration surrendered by the Optionee, provided that such risks of forfeiture and restrictions on transfer shall apply only to the same number of Shares received by the Optionee as applied to the forfeitable or restricted Shares surrendered by the Optionee.

A Stock Appreciation Right is the right of the Participant to receive from the Company an amount, which, shall be determined by the Committee and shall be expressed as a percentage (not exceeding 100 percent) of the Spread at the time of the exercise of such right. Any grant of Stock Appreciation Rights shall be upon such terms and conditions as the Committee may determine in accordance with the following provisions:

        7.1.    Payment in Shares.    Any amount payable upon the exercise of a Stock Appreciation Right shall be paid by the Company in Shares. Any grant may specify that the Shares payable upon the exercise of a Stock Appreciation Right shall not exceed a maximum specified by the Committee on the Grant Date.

        7.4.    Deemed Exercise.    The Committee may provide that a Stock Appreciation Right shall be deemed to be exercised at the close of business on the scheduled expiration date of such Stock Appreciation Right if at such time the Stock Appreciation Right by its terms remains exercisable and, if so exercised, would result in a payment of Shares to the holder of such Stock Appreciation Right.

        8.    Restricted Shares.    The Committee may also authorize grants to Participants of Restricted Shares upon such terms and conditions as the Committee may determine in accordance with the following provisions:

        8.1.    Transfer of Shares.    Each grant shall constitute an immediate transfer of the ownership of Shares to the Participant in consideration of the performance of services, subject to the substantial risk of forfeiture and restrictions on transfer referred to in Section 10. Each grant may be made without additional consideration from the Participant or in consideration of a payment by the Participant that is less than the Fair Market Value on the Grant Date.

        8.2.    Dividends.    Any grant may require that any or all dividends or other distributions paid on the Restricted Shares during the period of such restrictions be reinvested in additional Shares or held in cash,

B-9


which additional Shares or cash, as the case may be, may be subject to the same restrictions as the underlying Award or such other restrictions as the Committee may determine.

        9.    Deferred Shares.    The Committee may authorize grants of Deferred Shares to Participants upon such terms and conditions as the Committee may determine in accordance with the following provisions:

        9.1.    Deferred Transfer of Shares.    Each grant shall constitute the agreement by the Company to issue or transfer Shares to the Participant in the future in consideration of the performance of services, subject to the fulfillment during the Deferral Period of such conditions as the Committee may specify.

        10.    Vesting.    

        10.1.    In General.    Each grant of Options and Stock Appreciation Rights shall specify the period of continuous employment by the Company or any Subsidiary, or service to the Company or any Subsidiary (and in the case of a Nonemployee Director, service on the Board), of the Participant that is necessary before such Options or Stock Appreciation Rights, or installments thereof, shall become exercisable. Each grant of Restricted Shares shall specify the period during which such Restricted Shares shall be subject to a "substantial risk of forfeiture" within the meaning of Code Section 83, and each grant of Deferred Shares shall specify the Deferral Period to which such Deferred Shares shall be subject. Each grant of such Award may provide for the earlier exercise of rights, termination of a risk of forfeiture or termination of a Deferral Period in the event of a Change in Control or similar transaction or event.

        10.2.    Restrictions on Transfer of Restricted Shares.    Each grant of Restricted Shares shall provide that, during the period for which a substantial risk of forfeiture is to continue, the transferability of the Restricted Shares shall be prohibited or restricted in the manner and to the extent prescribed by the Committee on the Grant Date. Such restrictions may include, without limitation, rights of repurchase or first refusal by the Company or provisions subjecting the Restricted Shares to a continuing substantial risk of forfeiture in the hands of any transferee.

        11.    Dividends and Other Ownership Rights.    

        11.1.    Restricted Shares.    Unless otherwise determined by the Committee, an Award of Restricted Shares shall entitle the Participant to dividend, voting and other ownership rights during the period for which a substantial risk of forfeiture is to continue.

        11.2.    Deferred Shares.    Unless otherwise determined by the Committee, during the Deferral Period, the Participant shall not have any right to transfer any rights under an Award of Deferred Shares, shall not have any rights of ownership in the Deferred Shares and shall not have any right to vote such Shares.

        12.    Transferability.    

        12.1.    Transfer Restrictions.    Except as provided in Section 12.2, no Award granted shall be transferable by a Participant other than by will or the laws of descent and distribution, and Options and Stock Appreciation Rights shall be exercisable during a Participant's lifetime only by the Participant or, in the event of the Participant's legal incapacity, by his or her guardian or legal representative acting in a

B-10


fiduciary capacity on behalf of the Participant under state law. Any attempt to transfer an Award in violation of this Plan shall render such Award null and void.

        12.2.    Limited Transfer Rights.    The Committee may expressly provide in an Award Agreement (or an amendment to an Award Agreement) that a Participant may transfer such Award (other than an Incentive Stock Option), in whole or in part, to a spouse or lineal descendant (a "Family Member"), a trust for the exclusive benefit of Family Members, a partnership or other entity in which all the beneficial owners are Family Members, or any other entity affiliated with the Participant that may be approved by the Committee. Subsequent transfers of Awards shall be prohibited except in accordance with this Section 12.2. All terms and conditions of the Award, including without limitation provisions relating to termination of the Participant's employment or service with the Company or a Subsidiary, shall continue to apply following a transfer made in accordance with this Section 12.2. In order for a transfer to be effective, a Participant must agree in writing prior to the transfer on a form provided by the Company to pay any and all payroll and withholding taxes due upon exercise of the transferred Option. In addition, prior to the exercise of a transferred Option by a transferee, arrangements must be made by the Participant with the Company for the payment of all payroll and withholding taxes. Finally, the Company shall be under no obligation to provide a transferee with any notice regarding the transferred Awards held by the transferee upon forfeiture or any other circumstance.

        12.3.    Restrictions on Transfer.    Any Award granted may provide that all or any part of the Shares that are (a) to be issued or transferred by the Company upon the exercise of Options or Stock Appreciation Rights, upon termination of the Deferral Period applicable to Deferred Shares or upon payment under any grant of Performance Shares or Performance Units, or (b) no longer subject to the substantial risk of forfeiture and restrictions on transfer referred to in Section 10, shall be subject to further restrictions upon transfer, including restrictions relating to any minimum Share ownership requirements imposed by the Company with respect to a Participant.

        13.    Award Agreement.    Each grant under the Plan shall be evidenced by an Award Agreement, which shall describe the subject Award, state that the Award is subject to all of the terms and conditions of this Plan and contain such other terms and provisions as the Committee may determine consistent with this Plan.

        14.    Adjustments.    The Committee shall make or provide for appropriate adjustments in the (a) number of Shares covered by outstanding Options, Stock Appreciation Rights, Deferred Shares, Restricted Shares and Performance Shares granted hereunder, (b) prices per Share applicable to such Options and Stock Appreciation Rights, and (c) kind of Shares covered thereby (including Shares of another issuer), as the Committee in its sole discretion may in good faith determine to be equitably required in order to prevent dilution or enlargement of the rights of Participants that otherwise would result from (x) any stock dividend, stock split, combination or exchange of Shares, recapitalization or other change in the capital structure of the Company, (y) any merger, consolidation, spin-off, spin-out, split-off, split-up, reorganization, partial or complete liquidation or other distribution of assets (other than a normal cash dividend), issuance of rights or warrants to purchase securities, or (z) any other corporate transaction or event having an effect similar to any of the foregoing. Moreover, in the event of any such transaction or event, the Committee may provide in substitution for any or all outstanding Awards such alternative consideration as it may in good faith determine to be equitable under the circumstances and may require in

B-11


connection therewith the surrender of all Awards so replaced. The Committee may also make or provide for such adjustments in each of the limitations specified in Section 3 as the Committee in its sole discretion may in good faith determine to be appropriate in order to reflect any transaction or event described in this Section 14. The Company shall give each Participant notice of an adjustment hereunder and, upon notice, such adjustment shall be conclusive and binding for all purposes.

        15.    Fractional Shares.    The Company shall not be required to issue any fractional Shares pursuant to this Plan. The Committee may provide for the elimination of fractions or for the settlement thereof in cash.

        16.    Withholding Taxes.    The Company shall be entitled to deduct from any payment under the Plan, regardless of the form of such payment, the amount of all applicable income and employment taxes required by law to be withheld with respect to such payment or may require the Participant to pay to it such tax prior to and as a condition of the making of such payment. In accordance with any applicable administrative guidelines it establishes, the Committee may allow a Participant to pay the amount of taxes required by law to be withheld from an Award by withholding from any payment of Shares due as a result of such Award, or by permitting the Participant to deliver to the Company Shares having a Fair Market Value, as determined by the Committee, equal to the minimum amount of such required withholding taxes.

        17.    Certain Terminations of Employment, Hardship and Approved Leaves of Absence.    In the event of termination of employment by reason of death, disability, normal retirement, early retirement with the consent of the Committee, other termination of employment or a leave of absence that is approved by the Committee, or in the event of hardship or other special circumstances that are approved by the Committee, of a Participant who holds an Option or Stock Appreciation Right that is not immediately and fully exercisable, any Restricted Shares as to which the substantial risk of forfeiture or the prohibition or restriction on transfer has not lapsed, any Deferred Shares as to which the Deferral Period is not complete, any Performance Shares or Performance Units that have not been fully earned, or any Shares that are subject to any transfer restriction pursuant to Section 12.3, the Committee may, in its sole discretion, take any action that it deems to be equitable under the circumstances or in the best interests of the Company, including without limitation waiving or modifying any limitation or requirement with respect to any Award and providing for post-termination exercise periods with respect to any Option or Stock Appreciation Right.

        18.    Termination for Cause.    A Participant who is terminated for Cause shall, unless otherwise determined by the Committee, immediately forfeit, effective as of the date the Participant engages in such conduct, all unexercised, unearned, and/or unpaid Awards, including, but not by way of limitation, Awards earned but not yet paid or exercised, all unpaid dividends and all interest, if any, accrued on the foregoing.

        19.    Foreign Participants.    In order to facilitate the making of any grant or combination of grants under this Plan, the Committee may provide for such special terms for Awards to Participants who are foreign nationals, or who are employed by or perform services for the Company or any Subsidiary outside of the United States of America, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Moreover, the Committee may approve such supplements to, or amendments, restatements or alternative versions of, this Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of this Plan as in effect for any other purpose, provided that no such supplements, amendments, restatements or alternative versions shall include any provisions that are inconsistent with the terms of this Plan, as then in effect, unless this Plan could have been amended to eliminate such inconsistency without further approval by the stockholders of the Company.

B-12

        20.    Amendments and Other Matters.    

        20.1.    Plan Amendments.    This Plan may be amended from time to time by the Board, but no such amendment shall: (a) increase any of the limitations specified in Section 3, other than to reflect an adjustment made in accordance with Section 14, (b) change the class of persons eligible to receive grants of Awards or the types of Awards available under the Plan, or (c) increase the benefits to Participants under the Plan, in any such case without the further approval of the stockholders of the Company. The Board will also condition any amendment on the approval of the stockholders of the Company if such approval is necessary with respect to the applicable listing or other requirements of a national securities exchange or other applicable laws, policies or regulations, and the Board may condition any amendment on the approval of the stockholders of the Company if such approval is deemed advisable to comply with such requirements.

        20.2.    Award Deferrals.    An Award Agreement may provide that payment of any Award, dividend, or any portion thereof, may be deferred by a Participant until such time as the Committee may establish. All such deferrals shall be accomplished by the delivery of a written, irrevocable election by the Participant prior to the time established by the Committee for such purpose, on a form provided by the Company. Deferred Awards may also be credited with interest, at such rates to be determined by the Committee.

        20.3.    Conditional Awards.    The Committee may condition the grant of any Award or combination of Awards on the surrender or deferral by the Participant of his or her right to receive a cash bonus or other compensation otherwise payable by the Company or any Subsidiary to the Participant.

        20.4.    Repricing Prohibited.    No Award may be repriced, replaced, regranted through cancellation, or modified, directly or indirectly, without the approval of the stockholders of the Company, provided that nothing herein shall prevent the Committee from taking any action provided for in Section 14.

        20.5.    Amendments to Awards.    Subject to the requirements of Section 20.4, the Committee may at any time unilaterally amend any unexercised, unearned, or unpaid Award, including, but not by way of limitation, Awards earned but not yet paid, to the extent it deems appropriate (including for the purposes of compliance with local laws and regulations or to avoid costly government filings); provided, however, that except to the extent that the Committee determines that an amendment is necessary to avoid a penalty tax under Section 409A of the Code, any such amendment which, in the opinion of the Committee, is adverse to the Participant shall require the Participant's consent.

        20.6.    No Employment Right.    This Plan shall not confer upon any Participant any right with respect to continuance of employment or other service with the Company or any Subsidiary and shall not interfere in any way with any right that the Company or any Subsidiary would otherwise have to terminate any Participant's employment or other service at any time.

        20.7.    Compliance with Section 409A of the Code.    Notwithstanding any other provision of the Plan to the contrary, (a) to the extent that any payment of or in connection with an Award constitutes a payment under a "non-qualified deferred compensation plan," as defined in Section 409A of the Code, such payment shall be made in compliance with Section 409A of the Code and (b) any adjustment of Shares or prices per Share or substitution of Awards pursuant to Section 14 and any modification of Awards

B-13


pursuant to Section 17 shall not cause the affected Award to violate the requirements of Section 409A of the Code.

        21.    Change in Control.    Except as otherwise provided at the time of grant in an Award Agreement relating to a particular Award and subject to the requirements of Section 14, if a Change in Control occurs, then:

        21.1.   The Participant's Restricted Shares, Deferred Shares, Performance Shares, Performance Units or other Share-based Awards that were forfeitable shall, unless otherwise determined by the Committee prior to the occurrence of the Change in Control, become nonforfeitable and, to the extent applicable, shall be converted into Shares.

        21.2.   Any unexercised Option or Stock Appreciation Right, whether or not exercisable on the date of such Change in Control, shall thereupon be fully exercisable and may be exercised, in whole or in part.

        21.3.   Notwithstanding Sections 21.1 and 21.2, in the event of a Change in Control, the Committee may in its discretion cancel any outstanding Awards and (a) pay to the holders thereof, in cash or stock, or any combination thereof, the value of such Awards based upon the price per share of Stock received or to be received by other stockholders of the Company in the event or (b) arrange for fully vested substitute awards to be granted to the holders thereof, denominated in the equity of the acquirer or an affiliate thereof, provided such substitute awards substantially preserve the value of the substituted Awards.

        21.4.   If a Change in Control occurs during the term of one or more Performance Periods for which the Committee has granted performance-based Awards pursuant to the provisions of Section 5, the term of each such Performance Period (hereinafter a "current Performance Period") shall immediately terminate upon the occurrence of such Change in Control. Upon a Change in Control, for each current Performance Period and each completed Performance Period for which the Committee has not on or before such date made a determination as to whether and to what degree the Performance Objectives for such period have been attained (hereinafter a "completed Performance Period"), it shall be assumed that the Performance Objectives have been attained at a level of one hundred percent (100%) or the equivalent thereof. A Participant in one or more current Performance Periods shall be considered to have earned and, therefore, be entitled to receive, a prorated portion of the Award previously granted to him for each such current Performance Period. Such prorated portion shall be determined by multiplying the number of Performance Shares or Performance Units (or other performance-based Awards), as the case may be, granted to the Participant by a fraction, the numerator of which is the total number of days that have elapsed since the beginning of the current Performance Period, and the denominator of which is the total number of days in such current Performance Period. A Participant in one or more completed Performance Periods shall be considered to have earned and, therefore, be entitled to receive all the Performance Shares or Performance Units (or other performance-based Awards), as the case may be, previously granted to him during each such completed Performance Period.

        21.5.   Unless otherwise provided by the Committee, at any time, upon a Change in Control, any Awards deferred by a Participant under Section 20.2, but for which he or she has not received payment as of such date, shall be paid by the 90th day following the Change in Control.

B-14


        22.    Effective Date.    This Plan shall become effective upon its approval by the stockholders of the Company.

        23.    Termination.    This Plan shall terminate on the tenth anniversary of the date upon which it is approved by the stockholders of the Company, and no Award shall be granted after that date.

        24.    Arbitration of Disputes.    Any and all disputes arising out of or relating to the Plan or any Award Agreement (or breach thereof) shall be resolved exclusively through binding arbitration in the State of New York in accordance with the rules of the American Arbitration Association then in effect.

        25.    Regulatory Approvals and Listings.    Notwithstanding anything contained in this Plan to the contrary, the Company shall have no obligation to issue or deliver certificates of Shares evidencing Awards or any other Award resulting in the payment of Shares prior to (i) the obtaining of any approval from any governmental agency which the Company shall, in its sole discretion, determine to be necessary or advisable, (ii) the admission of such Shares to listing on the stock exchange or market on which the Shares may be listed, and (iii) the completion of any registration or other qualification of said Shares under any state or federal law or ruling of any governmental body which the Company shall, in its sole discretion, determine to be necessary or advisable. The Committee may, from time to time, impose additional restrictions upon an Award, including but not limited to, restrictions regarding tax withholdings and restrictions regarding the Participant's ability to exercise Awards under the Company's broker-assisted stock option exercise program.

        26.    No Right, Title, or Interest in Company Assets.    No Participant shall have any rights as a stockholder of the Company as a result of participation in the Plan until the date of issuance of a stock certificate in his or her name, and, in the case of Restricted Shares, such rights are granted to the Participant under the Plan. To the extent any person acquires a right to receive payments from the Company under the Plan, such rights shall be no greater than the rights of an unsecured creditor of the Company and the Participant shall not have any rights in or against any specific assets of the Company. All of the Awards granted under the Plan shall be unfunded.

        27.    No Guarantee of Tax Consequences.    Notwithstanding any other provision of the Plan, no person connected with the Plan in any capacity, including, but not limited to, the Company and its directors, officers, agents and employees, makes any representation, commitment, or guarantee that any tax treatment, including, but not limited to, federal, state and local income, estate and gift tax treatment, will be applicable with respect to the tax treatment of any Award, any amounts deferred under the Plan, or paid to or for the benefit of a Participant under the Plan, or that such tax treatment will apply to or be available to a Participant on account of participation in the Plan, or that any of the foregoing amounts will not be subject to the 20% penalty tax and interest under Section 409A of the Code.

        28.    Governing Law.    The validity, construction and effect of this Plan and any Award hereunder will be determined in accordance with the laws of the State of Delaware.

An Eligible Person who is a Covered Employee shall be entitled to participate in the Plan with respect to a Performance Period which has commenced only if he or she commenced employment on or before the beginning of each Performance Period or any later date described in Treasury Regulation 1.162-27(e)(2) (or any successor thereto).

        Section 5.    Awards; Participants.    Awards may be granted only to Eligible Persons with respect to each Performance Period, subject to the terms and conditions set forth in the Plan.

Such Participant's Award, if any, shall be calculated in accordance with the mathematical formula or matrix determined pursuant to Section 6 or 7, as applicable, and subject to the limitations set forth in Section 9 hereof. The Committee shall certify in writing the amount of such Award and whether each material term of the Plan relating to such Award has been satisfied.
