ARTICLE III

PERIOD OF EXERCISABILITY

Section 3.1. - Commencement of Exercisability

(a) Time Option.

(i) So long as the Optionee continues to be employed by the Company or its Subsidiaries, the Time Option shall become exercisable pursuant to the following schedule:

Date Time Option Becomes Exercisable	Percentage of Time Option Shares Granted As to Which Time Option Is Exercisable

After the first anniversary of the Initial Vesting Date	20	%

After the second anniversary of the Initial Vesting Date	40	%

After the third anniversary of the Initial Vesting Date	60	%

After the fourth anniversary of the Initial Vesting Date	80	%

After the fifth anniversary of the Initial Vesting Date	100	%

(ii) That portion of the Option intended to be an “incentive stock option” within the meaning of Section 422 of the Code (“ISO”) and that portion of the Option that is not intended to be an ISO (“NQSO”) shall each become exercisable ratably in accordance with the above schedule. For example, following the first anniversary of the Initial Vesting Date, 20% of the ISOs and 20% of the NQSOs shall be exercisable, while 40% of the ISOs and 40% of the NQSOs shall be exercisable following the second anniversary of the Initial Vesting Date, and so on.

(iii) Notwithstanding the foregoing, the Time Option shall become immediately exercisable as to 100% of the shares of Common Stock subject to such Time Option immediately prior to a Change of Control (but only to the extent such Time Option has not otherwise terminated or become exercisable).

(b) Performance Option.

(i) The Performance Option shall become exercisable with respect to 20% of the shares of Common Stock subject to such Option in respect of each Fiscal Year (beginning with the 2004 Fiscal Year) upon the achievement by the applicable division of the

Company (“Applicable Division”) (as set forth on Exhibit A) of the Performance Targets established in respect of each Fiscal Year of the Applicable Division and set forth on Exhibit A attached hereto; provided, however, that such Option shall only become exercisable as to 20% of the shares of Common Stock subject to such Option (each such 20% of the shares, a “Tranche”) on December 31 of each such Fiscal Year upon the occurrence of the Financial Statement Approval Date applicable to such Fiscal Year so long as either (i) the Optionee remains employed with the Company on the applicable Financial Statement Approval Date or (ii) an Interim Termination Event occurs between such December 31 and the applicable Financial Statement Approval Date. If the Applicable Division does not achieve its Annual Performance Target for any given Fiscal Year (a “Missed Year”), the Option shall not become exercisable in respect of such Fiscal Year, as set forth in the immediately preceding sentence; provided, however, that if the Applicable Division achieves the Cumulative Performance Target as established for any Fiscal Year subsequent to a Missed Year, then any prior percentage of the Option (the exercisability of which had not previously occurred) in respect of prior Missed Years shall become exercisable (but only to the extent such Option has not otherwise terminated or become exercisable). Notwithstanding the foregoing, the Option shall become exercisable as to 100% of the shares of Common Stock subject to such Option (to the extent such Option has not otherwise terminated or become exercisable) on the eighth anniversary of the Grant Date.

(ii) Notwithstanding the foregoing, upon the occurrence of a Change of Control prior to December 31, 2008, the Performance Option (to the extent such Performance Option has not otherwise terminated) shall be exercisable with respect to the number of shares of Common Stock equal to the total number of shares of Common Stock subject to the Performance Option multiplied by a fraction, (i) the numerator of which is the number of shares of Common Stock that have previously become exercisable in respect of prior Fiscal Years, plus, with respect to the Tranche that could have become vested in respect the Fiscal Year in which the Change of Control occurs, if the Board determines, in its sole discretion (which must be exercised in good faith) that, as of the date of the Change of Control, the Applicable Division would, but for the Change of Control, have achieved the Annual Performance Target for such year, a pro rata portion of such Tranche (based on the number of days that have elapsed in such Fiscal Year through the date of the Change of Control, relative to 365 days) (the “Pro-Rata Fiscal Year”) and (ii) the denominator of which is the maximum number of shares that could have become vested in such completed Fiscal Years (whether or not they actually vested), plus a pro-rata portion of the maximum number of shares that could have become vested for the Fiscal Year in which the Change of Control occurred. (See Exhibit I for an example of the application of this Section 3.1(b)(ii).) Notwithstanding the foregoing provisions of this Section 3.1(b), if the Board determines, in its sole discretion (exercised in good faith), that, as of the date of the Change of Control, the Applicable Division achieved the applicable Cumulative Performance Target set forth in Appendix A hereto, the Option shall become exercisable in full. The Board shall make such determination based on an interpolation of the applicable Fiscal Year goals set forth in Appendix A.

(c) Notwithstanding the foregoing, no Option which does not otherwise become exercisable in accordance with Section 3.1(a)(iii) or 3.1(b)(i) above shall become exercisable as to any additional shares of Common Stock following the termination of employment of the Optionee for any reason, and any Option which is non-exercisable as of the Optionee’s termination of employment (other than any Option which becomes exercisable in accordance with Section 3.1(a)(iii) or 3.1(b)(i)) shall immediately be cancelled.

Section 3.2. - Expiration of Options

Except as otherwise provided in Section 5 or 6 of the Management Stockholder’s Agreement, the Optionee may not exercise the Options to any extent after the first to occur of the following events:

(a) The tenth anniversary of the Grant Date;

(b) The tenth anniversary of the Grant Date if the Optionee’s employment is terminated by reason of death or Permanent Disability;

(c) The first anniversary of the date of the Optionee’s termination of employment by reason of Retirement, by the Company or any of its Subsidiaries without Cause (other than by reason of Permanent Disability) or by the Optionee for Good Reason;

(d) The date of an Optionee’s termination of employment with the Company or any of its Subsidiaries by the Optionee for any reason other than as set forth in Section 3.2(b) or (c) above (without regard to Section 5 or 6 of the Management Stockholder’s Agreement);

(e) The date of an Optionee’s termination of employment by the Company or any of its Subsidiaries for Cause;

(f) The date the Option is terminated pursuant to Section 5 or 6 of the Management Stockholder’s Agreement; or

(g) If the Committee so determines pursuant to Section 9 of the Plan, the effective date of either the merger or consolidation of the Company into another Person, or the exchange or acquisition by another Person of all or substantially all of the Company’s assets or 80% or more of its then outstanding voting stock, or the recapitalization, reclassification, liquidation or dissolution of the Company. At least ten days prior to the effective date of such merger, consolidation, exchange, acquisition, recapitalization, reclassification, liquidation or dissolution, the Committee shall give the Optionee notice of such event if the Option has then neither been previously fully exercised nor become unexercisable under this Section 3.2.

ARTICLE IV

EXERCISE OF OPTIONS

Section 4.1. - Person Eligible to Exercise

Except as otherwise provided in the Management Stockholder’s Agreement, during the lifetime of the Optionee, only he may exercise an Option or any portion thereof. After the death of the Optionee, any exercisable portion of an Option may, prior to the time when an Option becomes unexercisable under Section 3.2, be exercised by his personal representative or by any person empowered to do so under the Optionee’s will or under the then applicable laws of descent and distribution.

Section 4.2. - Partial Exercise

Any exercisable portion of an Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes unexercisable under Section 3.2; provided, however, that any partial exercise shall be for whole shares of Common Stock only.

Section 4.3. - Manner of Exercise

An Option, or any exercisable portion thereof, may be exercised solely by delivering to the Secretary or his office all of the following prior to the time when the Option or such portion becomes unexercisable under Section 3.2:

(a) Notice in writing signed by the Optionee or the other person then entitled to exercise the Option or portion thereof, stating that the Option or portion thereof is thereby exercised and indicating the extent to which the portion of the Option being exercised constitutes Incentive Stock Options, such notice complying with all applicable rules established by the Committee;

(b) Full payment (in cash, by check or by a combination thereof) for the shares with respect to which such Option or portion thereof is exercised;

(c) A bona fide written representation and agreement, in a form satisfactory to the Committee, signed by the Optionee or other person then entitled to exercise such Option or portion thereof, stating that the shares of stock are being acquired for his own account, for investment and without any present intention of distributing or reselling said shares except as may be permitted under the Securities Act of 1933, as amended (the “Act”), and then applicable rules and regulations thereunder, and that the Optionee or other person then entitled to exercise such Option or portion thereof will indemnify the Company against and hold it free and harmless from any loss, damage, expense or liability resulting to the Company if any sale or distribution of the shares by such person is contrary to the representation and agreement referred to above; provided, however, that the Committee may, in its reasonable discretion, take whatever additional actions it deems reasonably necessary to ensure the observance and performance of such representation and agreement and to effect compliance with the Act and any other federal or state securities laws or regulations;

(d) Full payment to the Company of all amounts which, under federal, state or local law, it is required to withhold upon exercise of the Option; and

(e) In the event the Option or portion thereof shall be exercised pursuant to Section 4.1 by any person or persons other than the Optionee, appropriate proof of the right of such person or persons to exercise the Option.

Without limiting the generality of the foregoing, the Committee may require an opinion of counsel acceptable to it to the effect that any subsequent transfer of shares acquired on exercise of an Option does not violate the Act and may issue stop-transfer orders covering such shares. Share certificates evidencing stock issued on exercise of this Option shall bear an appropriate legend referring to the provisions of subsection (c) above and the agreements herein. The written representation and agreement referred to in subsection (c) above shall, however, not be required if the shares to be issued pursuant to such exercise have been registered under the Act and such registration is then effective in respect of such shares. In addition to the foregoing, after a Public Offering (as defined in the Management Stockholder’s Agreement), the Optionee may, in the Committee’s good faith discretion, make payment of the exercise price (as required in Section 4.3(b) above) in shares of Common Stock that the Optionee has held for at least six months or otherwise pursuant to an irrevocable broker loan program established in accordance with applicable law.

Section 4.4. - Conditions to Issuance of Stock Certificates

The shares of stock deliverable upon the exercise of an Option, or any portion thereof, may be either previously authorized but unissued shares or issued shares, which have then been reacquired by the Company. Such shares shall be fully paid and nonassessable. The Company shall not be required to issue or deliver any certificate or certificates for shares of stock purchased upon the exercise of an Option or portion thereof prior to fulfillment of all of the following conditions:

(a) The obtaining of approval or other clearance from any state or federal governmental agency which the Committee shall, in its reasonable and good faith discretion, determine to be necessary or advisable; and

(b) The lapse of such reasonable period of time following the exercise of the Option as the Committee may from time to time establish for reasons of administrative convenience.

Section 4.5. - Rights as Stockholder

The holder of an Option shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any shares purchasable upon the exercise of the Option or any portion thereof unless and until certificates representing such shares shall have been issued by the Company to such holder.
