3. ADMINISTRATION OF PLAN.

(a)   The Plan shall be administered by the Committee appointed by the Board. Unless otherwise determined by the Board, the Committee, upon and after such time as it is covered in Section 16 of the Exchange Act, shall consist of at least two individuals each of whom shall be a “nonemployee director” as defined in Rule 16b-3 as promulgated by the Securities and Exchange Commission (“Rule 16b-3”) under the Exchange Act and shall, at such times as the Company is subject to Section 162(m) of the Code (to the extent relief from the limitation of Section 162(m) of the Code is sought with respect to Awards), qualify as “outside directors” for purposes of Section 162(m) of the Code; provided that no action taken by the Committee (including without limitation grants) shall be invalidated because any or all of the members of the Committee fails to satisfy the foregoing requirements of this sentence.  If and to the extent applicable, no member of the Committee may act as to matters under the Plan specifically relating to such member.  Notwithstanding the other foregoing provisions of this Section 3(a), any Award under the Plan to a person who is a member of the Committee shall be made and administered by the Board.  If no Committee is designated by the Board to act for these purposes, the Board shall have the rights and responsibilities of the Committee hereunder and under the Award Agreements.

(b)   Subject to the provisions of the Plan, the Committee shall in its discretion (i) authorize the granting of Awards to Eligible Persons; and (ii) determine the eligibility of Eligible Persons to receive an Award, as well as determine the number of Shares to be covered under any Award Agreement, considering the position and responsibilities of the Eligible Persons, the nature and value to the Company of the Eligible Person’s present and potential contribution to the success of the Company whether directly or through its Subsidiaries and such other factors as the Committee may deem relevant.

(c)   The Award Agreement shall contain such other terms, provisions and conditions not inconsistent herewith as shall be determined by the Committee.  In the event that any Award Agreement or other agreement hereunder provides (without regard to this sentence) for the obligation of the Company or any affiliate thereof to purchase or repurchase Shares from a Participant or any other person, then, notwithstanding the provisions of the Award Agreement or such other agreement, such obligation shall not apply to the extent that the purchase or repurchase would not be permitted under governing state law.  The Participant shall take whatever additional actions and execute whatever additional documents the Committee may in its reasonable judgment deem necessary or advisable in order to carry out or effect

5

one or more of the obligations or restrictions imposed on the Participant pursuant to the express provisions of the Plan and the Award Agreement.

(d)   The Committee may provide, in its discretion, that (i) all stock issued hereunder be initially maintained in separate brokerage account for the Participant at a brokerage firm selected by, and pursuant to an arrangement with, the Company; and (ii) in the case of vested Shares, the Participant may move such Shares to another brokerage account of the Participant’s choosing or request that a stock certificate be issued and delivered to him or her.

(e)   The Committee, in its discretion, may delegate to the Chief Executive Officer of the Company all or part of the Committee’s authority and duties with respect to awards, including, without limitation, the granting of awards to individuals who are not subject to the reporting and other provisions of Section 16 of the Act and who are not and are not expected to be “covered employees” within the meaning of Section 162(m) of the Code.  Any such delegation by the Committee may, in the sole discretion of the Committee, include a limitation as to the amount of awards that may be awarded during the period of the delegation and may contain guidelines as to the determination of the option exercise price, or price of other awards and the vesting criteria.  The Committee may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Committee’s delegate that were consistent with the terms of the Plan.

4. SHARES AND UNITS SUBJECT TO THE PLAN .

(a)   Subject to adjustments as provided in Section 14, the total number of Shares subject to Awards granted under the Plan, in the aggregate, may not exceed 7,000,000 (the “Fungible Pool Limit”).  Each Share issued or to be issued in connection with Full-Value Awards that vest or are granted based on the achievement of the performance goals set forth in Exhibit A shall be counted against the Fungible Pool Limit as 2.0 Fungible Pool Units.  Each Share issued or to be issued in connection with any other Full-Value Awards shall be counted against the Fungible Pool Limit as 3.0 Fungible Pool Units.  Options, Stock Appreciation Rights and other Awards that do not deliver the full value at grant thereof of the underlying Shares and that expire 10 years from the date of grant shall be counted against the Fungible Pool Limit as 1 Fungible Pool Unit.  Options, Stock Appreciation Rights and other Awards that do not deliver the full value at grant thereof of the underlying Shares and that expire five years from the date of grant shall be counted against the Fungible Pool Limit as 0.7 of a Fungible Pool Unit.  (For these purposes, the number of Shares taken into account with respect to a Stock Appreciation Right shall be the number of Shares underlying the Stock Appreciation Rights at grant (i.e., not the final number of Shares delivered upon exercise of the Stock Appreciation Rights).)  Shares that have been granted as Restricted Stock or that have been reserved for distribution in payment for Options, Phantom Shares or other equity-based Awards but are later forfeited or for any other reason are not payable under the Plan may again be made the subject of Awards under the Plan.

(b)   At the end of (i) the third calendar year following April 1, 2005 and (ii) the third calendar year following April 1, 2007, the Three-Year Average Annual Rate, respectively, shall not exceed the greater of (1) 2%, with respect to the third calendar year following April 1, 2005, or 2.23%, with respect to the third calendar year following April 1, 2007 or (2) the mean of the Company’s GICS peer group (collectively, the “Target Rate”).  For purposes of calculating the number of Shares granted in a year in connection with the limitation set forth in the foregoing sentence, Shares underlying Full-Value Awards will be taken into account as (i) 1.5 Shares if the Company’s annual Common Stock price volatility is 53% or higher, (ii) two Shares if the Company’s annual Common Stock price volatility is between 25% and 52%, and (iii) four Shares if the Company’s annual Common Stock price volatility is less than 25%.  (For the avoidance of doubt, the Annual Rate in any one year during such three-year

6

periods may exceed the applicable Target Rate, provided that the Three-Year Average Annual Rate does not exceed the applicable Target Rate.)

(c)   Shares subject to Dividend Equivalent Rights, other than Dividend Equivalent Rights based directly on the dividends payable with respect to Shares subject to Options or the dividends payable on a number of Shares corresponding to the number of Phantom Shares awarded, shall be subject to the limitation of Section 4.1(a).  If any Phantom Shares, Dividend Equivalent Rights or other equity-based Awards under Section 9 are paid out in cash, then, notwithstanding the first sentence of Section 4.1(a) above (but subject to the second sentence thereof) the underlying Shares may again be made the subject of Awards under the Plan.

(d)   The certificates for Shares issued hereunder may include any legend which the Committee deems appropriate to reflect any rights of first refusal or other restrictions on transfer hereunder or under the Award Agreement, or as the Committee may otherwise deem appropriate.

(e)   No award may be granted under the Plan to any person who, assuming exercise of all options and payment of all awards held by such person, would own or be deemed to own more than 9.8% of the outstanding shares of Common Stock.  Subject to adjustments as provided in Section 14, no Eligible Person shall be granted Awards (with Shares subject to Awards being counted, depending on the type of Award, in the proportions ranging from 0.7 to 3.0, as described in Section 4(a)) in any one year covering more than 700,000 Shares, it being expressly contemplated that Awards in exclusively one category (e.g., Options) can (but need not) be used in the discretion of the Committee to reach the limitation set forth in this sentence.

5. PROVISIONS APPLICABLE TO STOCK OPTIONS .

5.1 Grant of Option.

Subject to the other terms of the Plan, the Committee (or, as expressly permitted by Section 3, the Chief Executive Officer) shall, in its discretion as reflected by the terms of the applicable Award Agreement: (i) determine and designate from time to time those Eligible Persons to whom Options are to be granted and the number of Shares to be optioned to each Eligible Person; (ii) determine whether to grant Incentive Stock Options or to grant Non-Qualified Stock Options, or both (to the extent that any Option does not qualify as an Incentive Stock Option, it shall constitute a separate Non-Qualified Stock Option); provided that Incentive Stock Options may only be granted to employees; (iii) determine the time or times when and the manner and condition in which each Option shall be exercisable and the duration of the exercise period; (iv) designate each Option as one intended to be an Incentive Stock Option or as a Non-Qualified Stock Option; and (v) determine or impose other conditions to the grant or exercise of Options under the Plan as it may deem appropriate.

5.2 Option Price.

The Option Price shall be determined by the Committee on the date the Option is granted and reflected in the Award Agreement, as the same may be amended from time to time.  The Option Price shall not be less than 100% of the Fair Market Value of a Share on the day the Option is granted.  Any particular Award Agreement may provide for different exercise prices for specified amounts of Shares subject to the Option.

7

5.3 Period of Option and Vesting.

(a)   Unless earlier expired, forfeited or otherwise terminated, each Option shall expire in its entirety upon the 10th anniversary of the date of grant or shall have such other term (which may be shorter, but not longer) as is set forth in the applicable Award Agreement (except that, in the case of an individual described in Section 422(b)(6) of the Code (relating to certain 10% owners) who is granted an Incentive Stock Option, the term of such Option shall be no more than five years from the date of grant).  The Option shall also expire, be forfeited and terminate at such times and in such circumstances as otherwise provided hereunder or under the Award Agreement.

(b)   Each Option, to the extent that the Optionee has not had a Termination of Service and the Option has not otherwise lapsed, expired, terminated or been forfeited, shall first become exercisable according to the terms and conditions set forth in the Award Agreement, as determined by the Committee at the time of grant.  Unless otherwise provided in the Award Agreement, no Option (or portion thereof) shall ever be exercisable if the Optionee has a Termination of Service before the time at which such Option (or portion thereof) would otherwise have become exercisable, and any Option that would otherwise become exercisable after such Termination of Service shall not become exercisable and shall be forfeited upon such termination.  Notwithstanding the foregoing provisions of this Section 5.3(b), Options exercisable pursuant to the schedule set forth by the Committee at the time of grant may be fully or more rapidly exercisable or otherwise vested at any time in the discretion of the Committee.  Upon and after the death of an Optionee, such Optionee’s Options, if and to the extent otherwise exercisable hereunder or under the applicable Award Agreement after the Optionee’s death, may be exercised by the Successors of the Optionee.

5.4 Exercisability Upon and After Termination of Optionee.

(a)   Subject to provisions of the Award Agreement, in the event the Optionee has a Termination of Service other than by the Company or its Subsidiaries for Cause, or other than by reason of death, Retirement or Disability, no exercise of an Option may occur after the expiration of the three-month period to follow the termination, or if earlier, the expiration of the term of the Option as provided under Section 5.3(a); provided that, if the Optionee should die after the Termination of Service, such termination being for a reason other than Cause, Disability or Retirement, but while the Option is still in effect, the Option (if and to the extent otherwise exercisable by the Optionee at the time of death) may be exercised until the earlier of (i) one year from the date of the Termination of Service of the Optionee, or (ii) the date on which the term of the Option expires in accordance with Section 5.3(a).

(b)   Subject to provisions of the Award Agreement, in the event the Optionee has a Termination of Service on account of death or Disability or Retirement, the Option (whether or not otherwise exercisable) may be exercised until the earlier of (i) one year from the date of the Termination of Service of the Optionee, or (ii) the date on which the term of the Option expires in accordance with Section 5.3.

(c)   Notwithstanding any other provision hereof, unless otherwise provided in the Award Agreement, if the Optionee has a Termination of Service by the Company for Cause, the Optionee’s Options, to the extent then unexercised, shall thereupon cease to be exercisable and shall be forfeited forthwith.

5.5 Exercise of Options.

(a)   Subject to vesting, restrictions on exercisability and other restrictions provided for hereunder or otherwise imposed in accordance herewith, an Option may be exercised, and payment in full of the aggregate Option Price made, by an Optionee only by written notice (in the form prescribed by the Committee) to the Company specifying the number of Shares to be purchased.

8

(b)   Without limiting the scope of the Committee’s discretion hereunder, the Committee may impose such other restrictions on the exercise of Incentive Stock Options (whether or not in the nature of the foregoing restrictions) as it may deem necessary or appropriate.

5.6 Payment.

(a)   The aggregate Option Price shall be paid in full upon the exercise of the Option.  Payment must be made by one of the following methods:

(i)            a certified or bank cashier’s check or wire transfer;

(ii)           subject to Section 12(e), the proceeds of a Company loan program or third-party sale program or a notice acceptable to the Committee given as consideration under such a program, in each case if permitted by the Committee in its discretion, if such a program has been established and the Optionee is eligible to participate therein;

(iii)          if approved by the Committee in its discretion, Shares of previously owned Common Stock, which have been previously owned for more than six months, having an aggregate Fair Market Value on the date of exercise equal to the aggregate Option Price; or

(iv)          by any combination of such methods of payment or any other method acceptable to the Committee in its discretion.

(b)   Except in the case of Options exercised by certified or bank cashier’s check, the Committee may impose limitations and prohibitions on the exercise of Options as it deems appropriate, including, without limitation, any limitation or prohibition designed to avoid accounting consequences which may result from the use of Common Stock as payment upon exercise of an Option.

(c)   The Committee may provide that no Option may be exercised with respect to any fractional Share.  Any fractional Shares resulting from an Optionee’s exercise that is accepted by the Company shall in the discretion of the Committee be paid in cash.

5.7 Stock Appreciation Rights.

The Committee, in its discretion, may also permi
