7.  Terms and Conditions of Appreciation Rights.  

    (a) An
Appreciation Right may be granted in connection with an Option, either at the time of grant or at any time thereafter during the term of the Option. 

    (b) An
Appreciation Right granted in connection with an Option will entitle the holder, upon exercise, to surrender such Option or any portion thereof to the extent

Stock on the date of exercise of such Appreciation Right, by 

    (ii) The

B–4

 

    (f)  An Appreciation Right granted without relationship to an Option will entitle the holder, upon exercise of the Appreciation Right, to receive payment of an amount
determined by multiplying: 

     (i) The

applicable law) from the Fair Market Value of a share of Common Stock on the date of exercise of such Appreciation Right, by 

    (ii) The
number of shares as to which such Appreciation Right will have been exercised.

date of exercise of the Appreciation Right or alternatively, in the sole discretion of the Committee, solely in cash or a combination of cash and shares as the Committee deems advisable. If the
Committee decides that payment may be made in shares of Common Stock, and the amount payable results in a fractional share, payment for the fractional share will be made in cash. 

    (i)  An
Appreciation Right granted in connection with an Incentive Stock Option may be exercised only when the market price of the Common Stock subject to the Incentive
Stock Option exceeds the purchase price of a share of Common Stock related to the Incentive Stock Option.

shares of Incentive Stock Awards granted pursuant to the Plan will be subject to the following conditions:

under the Securities Act of 1933, as amended, under the requirements of any stock exchange upon which such shares of the same class are then listed and under any blue sky or other securities laws
applicable to such shares. 

    (v) The
Committee, in its sole discretion, may elect to settle all or a portion of an Incentive Stock Award in cash in lieu of issuing shares of Common Stock based on
the Fair Market Value on the date of payment.

Units granted to a Participant, a cash amount equivalent in value to the Fair Market Value of one share of Common Stock on the last day of the vesting period, subject to any maximum value determined
by the Committee at the time of grant, shall be paid with respect to each such Restricted Unit to the Participant. 

    During
the vesting period for Restricted Units, the Committee may provide that a Participant shall be paid with respect to each Restricted Unit, cash amounts in the same amount and at
the same time as a dividend on a share of Common Stock. 

11.  Adjustment Provisions.  

    (a) Subject
to Section 11(b), if the outstanding shares of Common Stock of the Company are increased, decreased, or exchanged for a different number or kind of
shares or other securities, or if additional shares or new or different shares or other securities are distributed with respect to such shares of Common Stock or other securities, through merger,
consolidation, spin off, sale of all or substantially all the property of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other
distribution with respect to such shares of Common Stock, or other securities, an appropriate and proportionate adjustment may be made in (i) the maximum number and kind of shares provided in
Section 3, (ii) the number and kind of shares, units, or other securities subject to the then-outstanding Incentive Awards, and (iii) the price for each share or other
unit of any other securities subject to then-outstanding Incentive Awards without change in the aggregate purchase price or value as to which such Incentive Awards remain exercisable or
subject to restrictions. 

    (b) Despite
the provisions of Section 11(a), upon dissolution or liquidation of the Company or upon a reorganization, merger, or consolidation of the Company
with one or more corporations as a 

B–6

 

result of which the Company is not the surviving corporation, or upon the sale of all or substantially all the property of the Company, all Incentive Awards then outstanding under the Plan will be
fully vested and exercisable and all restrictions will immediately cease, unless provisions are made in connection with such transaction for the continuance of the Plan and the assumption or the
substitution for such Incentive Awards of new incentive awards covering the stock of a successor employer corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number
and kind of shares and prices. 

    (c) Adjustments
under Section 11(a) and 11(b) will be made by the Committee, whose determination as to what adjustments will be made and the extent thereof will
be final, binding and conclusive. No fractional interest will be issued under the Plan on account of any such adjustments. 

    (d) In
the event a Change of Control occurs or in the event that any Person makes a filing under Sections 13(d) or 14(d) of the Exchange Act with respect to the
Company, the Committee may, in its sole discretion, without obtaining shareholder approval, take any one or more of the following actions with respect to all Eligible Persons and Participants: 

     (i) Accelerate
the exercise dates of any outstanding Appreciation Rights or Options, accelerate the vesting dates of outstanding Restricted Units or Incentive Stock
Awards or the performance period of outstanding Performance Units, make outstanding Appreciation Rights or Options fully vested and exercisable, or make outstanding Restricted Units fully vested and
outstanding Performance Units fully payable; 

    (ii) Determine
that all or any portion of conditions associated with any Incentive Award have been met; 

    (iii) Grant
a cash bonus award to any of the holders of outstanding Options; 

    (iv) Grant
Appreciation Rights to holders of outstanding Options; 

    (v) Pay
cash to any or all Option holders in exchange for the cancellation of their outstanding Options; 

    (vi) Make
any other adjustments or amendments to the Plan and outstanding Incentive Awards and substitute new Incentive Awards. 

    For
purposes of this Section 11(d), the following definitions shall apply: 

	(A)
	A
"Change in Control" of the Company shall have occurred when a Person, alone or together with its Affiliates and Associates, becomes the beneficial owner of 20% or more of the
general voting power of the Company.

	(B)
	"Affiliate"
and "Associate" shall have the respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under the Exchange Act.

	(C)
	"Person"
shall mean an individual, firm, corporation or other entity or any successor to such entity, but "Person" shall not include the Company, any subsidiary of the Company, any
employee benefit plan or employee stock plan of the Company, or any Person organized, appointed, established or holding Voting Stock by, for or pursuant to the terms of such a plan or any Person who
acquires 20% or more of the general voting power of the Company in a transaction or series of transactions approved prior to such transaction or series of transactions by the Board.

	(D)
	"Voting
Stock" shall mean shares of the Company's capital stock having general voting power, with "voting power" meaning the power under ordinary circumstances (and not merely upon

12.  General Provisions.  

    (a) Nothing
in the Plan or in any instrument executed pursuant to the Plan will confer upon any Participant who is an Employee any right to continue in the employ of
the Company or any of its subsidiaries or affect the right of the Company to terminate the employment of such Participant or terminate the consulting or advisory services of any Participant at any
time with or without cause. 

    (b) No
shares of Common Stock will be issued or transferred pursuant to an Incentive Award unless and until all then-applicable requirements imposed by
federal and state securities and other laws, rules and regulations and by any regulatory agencies having jurisdiction, and by any stock exchanges upon which the Common Stock may be listed, have been
fully met. As a condition precedent to the issuance of shares pursuant to the grant or exercise of an Incentive Award, the Company may require the Participant to take any reasonable action to meet
such requirements. 

    (c) No
Participant and no beneficiary or other person claiming under or through such Participant will have any right, title or interest in or to any shares of Common
Stock allocated or reserved under the Plan or subject to any Incentive Award except as to such shares of Common Stock, if any, that have been issued or transferred to such Participant. 

    (d) The
Company shall have the right to deduct from any settlement, including the delivery or vesting of shares or Units, made under the Plan any federal, state or
local taxes of any kind required by law to be withheld with respect to such payments or take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the
payment of such taxes. With respect to any nonqualified stock Option, the Committee may, in its discretion, permit the Participant to satisfy, in whole or in part, any tax withholding obligation which
may arise in connection with the exercise of the nonqualified stock Option by electing to have the Company withhold shares of Common Stock having a Fair Market Value equal to the amount of the tax
withholding. 

    (e) No
Incentive Award and no right under the Plan, contingent or otherwise, will be transferable, assignable or subject to any encumbrances, pledge or charge of any
nature except that, under such rules and regulations as the Company may establish pursuant to the terms of the Plan, a beneficiary may be designated with respect to an Incentive Award in the event of
death of a Participant. If such beneficiary is the executor or administrator of the estate of the Participant, any rights with respect to such Incentive Award may be transferred to the person or
persons or entity (including a trust) entitled thereto. 

    (f)  The
Company may make a loan to a Participant in connection with (i) the exercise of an Option in an amount not to exceed the aggregate exercise price of the Option
being exercised and the amount of any federal and state taxes payable in connection with such exercise for the purpose of assisting such optionee to exercise such Option and (ii) an Incentive
Stock Award or Performance Unit paid in Common Stock in an amount not to exceed the amount of any federal and state taxes payable upon expiration of any applicable forfeiture provision, performance
period or vesting period for the purpose of assisting the holder of the Incentive Stock Award or Performance Unit to enjoy the rights thereunder. Any such loan may be secured by shares of Common Stock
or other collateral deemed adequate by the Committee and will comply in all respects with all applicable laws and regulations. The Committee may adopt policies regarding eligibility for such loans,
the maximum amounts thereof and any terms and conditions not specified in the Plan upon which such loans will be made. Such loans will bear interest at a rate determined by the Committee. 

    (g) The
Committee may cancel, with the consent of the Participant, all or a portion of any Option or Appreciation Right granted under the Plan to be conditioned upon
the granting to the Participant of a new Option or Appreciation Right for the same or a different number of shares as the Option or Appreciation Right surrendered, or may require such voluntary
surrender as a condition to a grant of a new Option or Appreciation Right to such Participant. Subject to the provisions of Section 6(d), such 

B–8

 

new Option or Appreciation Right shall be exercisable at the price, during the period and in accordance with any other terms or conditions specified by the Committee at the time the new Option or
Appreciation Right is granted, all determined in accordance with the provisions of the Plan without regard to the price, period of exercise, or any other terms or conditions of the Option or
Appreciation Right surrendered. 

    (h) The
forms of Options and Appreciation Rights granted under the Plan may contain such other provisions as the Committee may deem advisable. 

13.  Amendment and Termination.  

    (a) The
Board will have the power, in its discretion, to amend, suspend or terminate the Plan at any time, subject to approval of the shareholders of the Company to the
extent necessary for the continued applicability of Rule 16b-3 under the Exchange Act. 

    (b) The
Committee may, with the consent of a Participant, make such modifications in the terms and conditions of an Incentive Award agreement as it deems advisable. 

    (c) No
amendment, suspension or termination of the Plan will, without the consent of the Participant, alter, terminate, impair or adversely affect any right or
obligation under any Incentive Award previously granted under the Plan. 

    (d) An
Appreciation Right or an Option held by a person who was an Employee at the time such Appreciation Right or Option was granted will expire immediately if and
when the Participant ceases to be an Employee, except as follows: 

     (i) If
the employment of an Employee is terminated by the Company other than for cause, for which the Company will be the sole judge, then the Appreciation Rights and
Options will expire three months thereafter unless by their terms they expire sooner. During said period, the Appreciation Rights and Options may be exercised in accordance with their terms, but only
to the extent exercisable on the date of termination of employment. 

    (ii) If
the Employee retires at normal retirement age or retires with the consent of the Company at an earlier date or becomes permanently and totally disabled, as
determined by the Committee, while employed by the Company, the Appreciation Rights and Options of the Employee will be exercisable and will expire in accordance with their terms. 

    (iii) If
an Employee dies while employed by the Company, the Appreciation Rights and Options of the Employee will become fully exercisable as of the date of death and
will expire three years after the date of death unless by their terms they expire sooner. If the Employee dies or becomes permanently and totally disabled as determined by the Committee within the
three months referred to in subparagraph (i) above, the Appreciation Rights and Options will become fully exercisable as of the date of death or such permanent disability and will expire, in
the case of death, one year after the date of such death. In the case of permanent and total disability such Options and Appreciation Rights will expire in accordance with their terms. If the Employee
dies or becomes permanently and totally disabled as determined by the Committee subsequent to the time the Employee retires at normal retirement age or retires with the consent of the Company at an
earlier date, the Appreciation Rights and Options will fully vest as of the date of death or permanent and total disability and will expire, in the case of death, one year after the date of death. In
the case of permanent and total disability, such Appreciation Rights and Options will expire in accordance with their terms. 

    (e) In
the event a holder of Incentive Stock Awards, Performance Units or Restricted Units ceases to be an Employee, all such Incentive Stock Awards, Performance Units
or Restricted Units 

B–9

 

subject to restrictions at the time his or her employment terminates will be returned to the Company unless the Committee determines otherwise except as follows: 

     (i) In
the event the holder of Incentive Stock Awards or Restricted Units ceases to be an Employee due to death all such Incentive Stock Awards or Restricted Units
subject to restrictions at the time his or her employment terminates will no longer be subject to said restrictions. 

    (ii) If
an Employee retires at normal retirement age or retires with the consent of the Company at an earlier date or becomes permanently and totally disabled as
determined by the Committee, all such Incentive Stock Awards, Performance Units and Restricted Units will continue to vest over the
applicable vesting or performance period provided that during these periods such Employee does not engage in or assist any business that the Company, in its sole discretion, determines to be in
competition with businesses engaged in by the Company. 

    (iii) In
the event a holder of Performance Units ceases to be an Employee prior to the end of a performance period applicable thereto, the Committee in its sole
discretion shall determine whether to make any payment to the Participant in respect of such Performance Unit and the timing of such payment, if any. 

    (f)  The
Committee may in its sole discretion determine, (i) with respect to an Incentive Award, that any Participant who is on leave of absence for any reason
will be considered as still in the employ of the Company, provided that rights to such Incentive Award during a leave of absence will be limited to the extent to which such right was earned or vested
at the commencement of such leave of absence, or (ii) with respect to any Appreciation Rights and Options of any Employee who is retiring at normal retirement age or with the consent of the
Company at an earlier age, or of an Employee who becomes permanently and totally disabled as determined by the Committee that the Appreciation Rights and/or Options of such Employee will accelerate
and become fully exercisable on a date specified by the Committee which is not later than the effective date of such Employee's retirement or on a date specified by the Committee which is not later
than the date that the Employee becomes permanently and totally disabled as determined by the Committee. 

14.  Effective Date of Plan and Duration of Plan.  

    This Plan will become effective upon adoption by the Board subject to approval by the holders of a majority of the shares which are represented in person or by
proxy and entitled to vote on the subject at the 1991 Annual Meeting of Shareholders of the Company. Unless previously terminated, the Plan will terminate on September 25, 2006 except with
respect to Incentive Awards then outstanding.
