  date equal to the total option price, or by any combination of cash, Shares
  and other consideration as the Committee may specify in the applicable Award
  Agreement.

(e)    INCENTIVE
  STOCK OPTIONS. In accordance with rules and procedures established by the Committee,
  the aggregate Fair Market Value (determined as of the time of grant) of the
  Shares with respect to which Incentive Stock Options held by any Participant
  which are exercisable for the first time by such Participant during any calendar

  any parent or subsidiary corporation of the Company) shall not exceed $100,000
  or, if different, the maximum limitation in effect at the time of grant under
  Section 422 of the Code, or any successor provision, and any regulations promulgated

  comply in all respects with the provisions of Section 422 of the Code, or any
  successor provision, and any regulations promulgated thereunder.

(f)    FORM
  OF SETTLEMENT. In its sole discretion, the Committee may provide, at the time

  upon termination until the earlier of ninety days following termination of employment

      M = the number of complete months elapsed since the grant date of the Option,

      the date on which the Option was originally scheduled to become completely
      exercisable, and

      already become exercisable (regardless of whether the Option has been exercised

of Stock Appreciation Rights need not be the same with respect to each
recipient. Any Stock Appreciation Right related to a Nonstatutory Stock Option may be
granted at the same time such Option is granted or at any time thereafter before exercise
or expiration of such Option. Any Stock Appreciation Right related to an Incentive Stock
Option must be granted at the same time such Option is granted. In the case of any Stock
Appreciation Right related to any Option, the Stock Appreciation Right or applicable
portion thereof shall terminate and no longer be exercisable upon the termination or
exercise of the related Option, except that a Stock Appreciation Right granted with
respect to less than the full number of Shares covered by a related Option shall not be
reduced until the exercise or termination of the related Option exceeds the number of
Shares not covered by the Stock Appreciation Right. Any Option related to any Stock
Appreciation Right shall no longer be exercisable to the extent the related Stock
Appreciation Right has been exercised. The Committee may impose such conditions or
restrictions on the exercise of any Stock Appreciation Right as it shall deem appropriate.

SECTION

but subject to Section 11(a)(ii), unless the Committee shall determine otherwise
at the time of grant with respect to a particular Award, in the event of a Change
in Control:

|(1) |  | Any Options
        and Stock Appreciation Rights outstanding as of the date such Change in
        Control is determined to have occurred, and which are not then exercisable
        and vested, shall become fully exercisable and vested.
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) |  | The restrictions
        and deferral limitations applicable to any Restricted Stock Awards shall
        lapse, and such Restricted Stock Awards shall become free of all restrictions
        and limitations and become fully vested and transferable.
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) |  | All Performance
        Awards shall be considered to be earned and payable in full, and any deferral
        or other restriction shall lapse and such Performance Awards shall be

|--- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) |  | The restrictions
        and deferral limitations and other conditions applicable to any Other
        Stock Unit Awards or any other Awards shall lapse, and such Other Stock
        Unit Awards or such other Awards shall become free of all restrictions,

| |  | for outstanding Awards, then
        all such Awards shall become immediately and fully exercisable (or in
        the case of Restricted Stock Awards, Performance Awards or Other Stock
        Unit Awards, fully vested and all restrictions will immediately lapse).
        In addition, the Committee may in its sole discretion, provide for a cash
        payment to be made to each Participant upon consummation of the Change
        in Control for the outstanding Awards held by such Participant, determined
        on the basis of the value that would be received in such Change in Control
        by the holders of the Companys securities relating to such Awards.
        Notwithstanding the foregoing, any Option intended to be an Incentive
        Stock Option shall be adjusted in a manner to preserve such status.
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) |  | If the
        Company is the surviving Person following a Change in Control, or the
        Acquiror assumes the outstanding Awards or substitutes equivalent equity
        awards relating to the securities of the Acquiror or its Affiliates for
        such Awards, then all such Awards or such substitutes therefore shall
        remain outstanding and be governed by their respective terms and the provisions
        of the Plan.

|(3) |  | If (A)
        the employment of a Participant with the Company is terminated (1) other
        than for Cause or (2) by the Participant for Good Reason, in either case
        within 24 months following a Change in Control, and (B) the Company is
        the surviving Person following the Change in Control, or the Acquiror
        assumes the outstanding Awards or substitutes equivalent equity awards
        relating to the securities of the Acquiror or its Affiliates for such
        Awards, then all Awards held by such Participant shall become immediately
        and fully exercisable (or in the case of Restricted Stock Awards, Performance
        Awards or Other Stock Unit Awards, fully vested and all restrictions will
        immediately lapse).

(b)    CHANGE IN CONTROL
  CASH-OUT. (i) Notwithstanding any other provision of the Plan (other than Section
  11(b)(ii)), during the 60-day period from and after a Change in Control (the
  Exercise Period), if the Committee shall determine at, or at any
  time after, the time of grant, a Participant holding an Option shall have the
  right, whether or not the Option is fully exercisable and in lieu of the payment
  of the purchase price for the Shares being purchased under the Option and by
  giving notice to the Company, to elect (within the Exercise Period) to surrender
  all or part of the Option to the Company and to receive cash, within 30 days
  of such notice, in an amount equal to the amount by which the Change in Control
  Price per Share on the date of such election shall exceed the purchase price
  per Share under the Option (the Spread) multiplied by the number
  of Shares granted under the Option as to which the right granted under this
  Section 11(b) shall have been exercised.

(ii)    
  This Section 11(b)(ii), rather than Section 11(b)(i), shall apply to Options
  granted after February 21, 2002. Following a Change in Control, the Committee
  may cancel all outstanding Options and in lieu thereof, provide for the payment
  to each holder of an outstanding Option, whether or not such Option was then
  exercisable, of an amount equal to the amount by which the Change in Control
  Price per Share on the date of the Change in Control shall exceed

-12-

the purchase
  price per Share under the Option multiplied by the number of Shares subject
  to such Option.

**SECTION
  12. CODE SECTION 162(m) PROVISIONS.**

(a)    
  Notwithstanding any other provision of this Plan, if the Committee determines
  at the time Restricted Stock, a Performance Award or an Other Stock Unit Award
  is granted to a Participant that such Participant is, or may be as of the end
  of the tax year for which the Company would claim a tax deduction in connection
  with such Award, a Covered Employee, then the Committee may provide that this
  Section 12 is applicable to such Award under such terms as the Committee shall
  determine.

(b)    
  If an Award is subject to this Section 12, then the lapsing of restrictions
  thereon and the distribution of cash, Shares or other property pursuant thereto,
  as applicable, shall be subject to the Company having a level of Net Income
  for such period of time as is determined by the Committee, such level of Net
  Income to be set by the Committee within the time prescribed by Section 162(m)
  of the Code or the regulations thereunder in order for the level to be considered
  pre-established. The Committee may, in its discretion, reduce the
  amount of any Performance Award or Other Stock Unit Award subject to this Section
  12 at any time prior to payment based on such criteria as it shall determine,
  including but not limited to individual merit and the attainment of specified
  levels of one or any combination of the following: net cash provided by operating
  activities, earnings per Share from continuing operations, operating income,
  revenues, gross margin, return on operating assets, return on equity, economic
  value added, stock price appreciation, total stockholder return (measured in
  terms of stock price appreciation and dividend growth), or cost control, of
  the Company or the Subsidiary or division of the Company for or within which
  the Participant is primarily employed.

(c)    
  Notwithstanding any contrary provision of the Plan other than Section 11, the
  Committee may not adjust upwards the amount payable pursuant to any Award subject
  to this Section 12, nor may it waive the achievement of the Net Income requirement
  contained in Section 12(b), except in the case of the death or disability of
  a Participant.

(d)    
  Prior to the payment of any Award subject to this Section 12, the Committee
  shall certify in writing that the Net Income requirement applicable to such
  Award was met.

(e)    
  The Committee shall have the power to impose such other restrictions on Awards
  subject to this Section 12 as it may deem necessary or appropriate to ensure
  that such Awards satisfy all requirements for performance-based compensation
  within the meaning of Section 162(m)(4)(C) of the Code, the regulations promulgated
  thereunder, and any successors thereto.

SECTION

  of shares reserved for the purpose of the Plan; or

(b)

lifetime, only by the Participant or, if permissible under applicable law, by

  shall have any claim to be granted any Award under the Plan and there is no
  obligation for uniformity of treatment of Employees or Participants under the
  Plan.

(d)    The prospective recipient
  of any Award under the Plan shall not, with respect to such Award, be deemed
  to have become a Participant, or to have any rights with respect to such Award,
  unless and until

|(1) |  | if required
        by the Committee, such recipient shall have executed or accepted pursuant
        to procedures established by the Committee, a written or electronic agreement
        or other instrument evidencing the Award and delivered a fully executed

  the Plan or any Award in the manner and to the extent it shall deem desirable.

(f)    All certificates for
  Shares delivered under the Plan pursuant to any Award shall be subject to such
  stock-transfer orders and other restrictions as the Committee may deem advisable
  under the rules, regulations, and other requirements of the Securities and Exchange
  Commission, any stock exchange upon which the Shares are then listed, and any
  applicable Federal or state securities law, and the Committee may cause a legend
  or legends to be put on any such certificates to make appropriate reference
  to such restrictions.

(g)    Subject to the provisions
  of this Plan and any Award Agreement, the recipient of an Award (including,
  without limitation, any deferred Award) may, if so determined by the Committee,
  be entitled to receive, currently or on a deferred basis, interest or dividends,
  or interest or dividend equivalents, with respect to the number of Shares covered
  by the Award, as determined by the Committee, in its sole discretion, and the
  Committee may provide that such amounts (if any) shall be deemed to have been
  reinvested in additional Shares or otherwise reinvested.

(h)    Except as otherwise
  required in any applicable Award Agreement or by the terms of the Plan, recipients
  of Awards under the Plan shall not be required to make any payment or provide
  consideration other than the rendering of services.

  by law, the Committee may delegate to one or more directors of the Company (who
  need not be members of the Committee) the right to grant Awards to Employees
  who are not officers of the Company for purposes of Section 16 of the Exchange
  Act or directors of the Company and may delegate to any Officer its other authority
  hereunder, including the authority to amend, administer, interpret, waive conditions
  with respect to, cancel or suspend Awards to Employees who are not such officers.

procedures for election by Participants to satisfy such

  applicable by the Committee, such provision shall be construed or deemed amended
  to conform to applicable laws or if it cannot be construed or deemed amended
  without, in the determination of the Committee, materially altering the intent
  of the Plan, it shall be stricken and the remainder of the Plan shall remain
  in full force and effect.

(p)    Awards may be granted
  to Employees who are foreign nationals or employed outside the United States,
