 This Plan was adopted by the Board on December 8, 1988, and was last amended and restated effective December 2, 1999. 
  

	 	4.	ADMINISTRATION. 

  
 The Plan shall be administered by a committee (the “Committee”) appointed by the Board, consisting of not less than three disinterested members
thereof. The Board may from time to time remove members from, or add members to, the Committee. Vacancies on the Committee, howsoever caused shall be filled by the Board. The Board shall appoint one of the members of the Committee as Chairman. The

 The Committee shall hold meetings at such times and places as it may determine. Acts of a majority of the Committee at which

 4 








 
vesting of Awards, the designation of Options as Incentive Stock Options or Nonqualified Stock Options and other conditions of Awards. 
  
 The interpretation and construction by the Committee of any provisions of the
Plan or of any Award granted thereunder shall be final. No member of the Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Award granted thereunder. 
  

	 	5.	ELIGIBILITY. 

  
 Participants shall be such key Employees (who may be officers, whether or not they are directors) of the Corporation or of its Subsidiaries as the
Committee shall select, but subject to the terms and conditions set forth below. 
  
 (a) Ten Percent Shareholders. 
  
 An Employee who owns more than ten percent (10%) of the total combined voting power of all classes of outstanding stock of the Corporation, its parent or any of its Subsidiaries is not eligible to receive an Incentive Stock Option
pursuant to this Plan. For purposes of this Section 5(a) the stock ownership of an Employee shall be determined pursuant to section 425(d) of the Code. 
  
 (b) Number of Awards. 
  
 A Participant may receive more than one Award, including Awards of the same type, but only on the terms and subject to the restrictions hereinafter set
forth. 
  

	 	6.	STOCK. 

  
 The stock subject to Options, Restricted Stock, or Other Share-Based Awards granted under the Plan shall be Shares of the Corporation’s authorized
but unissued or reacquired Common Stock. The aggregate number of Options, Restricted 

  

 5 








 
Stock or Other Share-Based Awards issued under this Plan shall not exceed one million, five hundred thousand (1,500,000) Shares. The number of Shares
subject to Awards outstanding under the Plan at any time may not exceed the number of Shares remaining available for issuance under the Plan. In the event that any outstanding Option under the Plan for any reason expires or is terminated or any
Restricted Stock or Other Share-Based Award is forfeited, the Shares allocable to the unexercised portion of such Option or the forfeited Restricted Stock or Other Share-Based Award may again be subjected to Options, Restricted Stock or Other
Share-Based Awards under the Plan. However, if one Award is granted in tandem with another, so that the exercise of one causes the other to expire, then the number of shares subject to the expired Award shall not be restored to the pool available
for Awards. 
  
 The limitations established by this Section 6
shall be subject to adjustment upon the occurrence of the events specified and in the manner provided in Section 11 hereof. 
  

	 	7.	TERMS AND CONDITIONS OF OPTIONS. 

  
 Options granted pursuant to the Plan shall be evidenced by written Option Agreements in such form as the Committee shall from time to time determine which
agreements shall comply with and be subject to the following terms and conditions: 
  
 (a) Optionee’s Agreement. 
  
 Each Optionee shall agree to remain in the employ of and to render to the Corporation or to a Subsidiary his or her services for a period of one (1) year from the date of the granting of the Option, subject to the terms of
Section 12(b). 
  

 6 








 (b) Number of Shares. 
  
 Each option shall state the number of Shares to which it pertains and shall provide for the adjustment thereof in accordance
with the provisions of Section 11 hereof. 
  

 7 








 (c) Exercise Price. 
  
 Each Option shall state the Exercise Price, which in the case of an Incentive Stock Option shall not be less than the Fair
Market Value of a Share on the date of grant. 
  
 (d) Medium
and Time of Payment. 
  
 The Purchase Price shall be payable
in full in United States dollars upon the exercise of the Option; provided, however, that, with the consent of the Committee and in accordance with its rules, the Purchase Price may be paid by the surrender of Shares in good form for transfer, owned
by the person exercising the Option and having a Fair Market Value on the date of exercise equal to the Purchase Price, or in any combination of cash and Shares, so long as the total of the cash so paid and the Fair Market Value of the Shares
surrendered equals the Purchase Price. No Share shall be issued until full payment therefor has been made. 
  
 (e) Term and Exercise of Options; Nontransferability of Options. 
  
 Each Option shall state the time or times when it becomes exercisable and the time or times any stock appreciation right
granted pursuant to Section 7(j) may be called, which shall be determined by the Committee. No Option shall be exercisable after the expiration of ten (10) years from the date it is granted. During the lifetime of the Optionee, the option
shall be exercisable only by the Optionee and shall not be assignable or transferable. In the event of the Optionee’s death, no Option shall be transferable by the optionee otherwise than by will or the laws of descent and distribution.

  

 8 








 Subject to the foregoing, beginning six (6) months from the date of grant the Optionee shall have
the right to exercise the option (or in lieu thereof to call the related stock appreciation right as described in Section 7(j)) in whole or in part: 
  
 (i) Upon consummation of a reorganization, merger or consolidation involving the Corporation (a “Business Combination”), in each
case, unless, following such Business Combination, (A) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the then outstanding shares of Common Stock (the “Outstanding Common
Stock”) and then outstanding voting securities of the Corporation entitled to vote generally in the election of directors (the “Outstanding Voting Securities”) immediately prior to such Business Combination beneficially own, directly
or indirectly, more than 50% of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors of the corporation resulting
from such Business Combination (including, without limitation, a corporation which as a result of such transaction owns the Corporation either directly or through one or more subsidiaries), (B) no Person (as defined in subparagraph
(iii) below) (excluding any corporation resulting from such Business Combination or any employee benefit plan (or related trust) sponsored or maintained by the Corporation or such other corporation resulting from such Business Combination)
beneficially owns, directly or indirectly, 20% or more of, respectively, the then outstanding shares of common stock of the corporation resulting from such Business Combination or the combined voting power of the 

  

 9 








 
then outstanding voting securities of such corporation except to the extent that such ownership is based on the beneficial ownership, directly or indirectly,
of Outstanding Common Stock or Outstanding Voting Securities immediately prior to the Business Combination and (C) at least a majority of the members of the board of directors of the corporation resulting from such Business Combination were
members of the Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination; provided, however, if the Corporation and the other party to the Business Combination agree that the
transaction is to be treated as a pooling of interests for financial reporting purposes, and if the transaction in fact is so treated, then the right to exercise the Option (or to call the related stock appreciation right) shall not be accelerated
upon consummation of the Business Combination to the extent that the Corporation’s independent accountants and the other party’s independent accountants separately determine in good faith that the acceleration would preclude the use of
pooling of interests accounting; or 
  
 (ii) On
the date that individuals who, as of December 2, 1999 constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director
subsequent to December 2, 1999 whose election, or nomination for election by the Corporation’s stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though
such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of 

  

 10 








 
office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors, an actual or threatened
solicitation of proxies or consents or any other actual or threatened action by, or on behalf of any Person other than the Board; or 
  
 (iii) Upon the acquisition after December 2, 1999 by any individual, entity or group (within the meaning of Section 13(d)(3) or
14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (a “Person”) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either (A) the
then Outstanding Common Stock or (B) the combined voting power of the Outstanding Voting Securities; provided, however, that the following acquisitions shall not be deemed to be covered by this subsection (iii): (x) any acquisition of
Outstanding Common Stock or Outstanding Voting Securities by the Corporation, (y) any acquisition of Outstanding Common Stock or Outstanding Voting Securities by any employee benefit plan (or related trust) sponsored or maintained by the
Corporation or (z) any acquisition of Outstanding Common Stock or Outstanding Voting Securities by any corporation pursuant to a transaction which complies with clauses (A), (B) and (C) of subsection (i) of this
Section 7(e); or 
  
 (iv) Upon the
consummation of the sale of all or substantially all of the assets of the Corporation or approval by the stockholders of the Corporation of a complete liquidation or dissolution of the Corporation. 
  
 (f) Termination of Employment Except Death. 
  

 11 








 Except as provided in Subsection (k) below, in the event that an Optionee shall cease to be employed
by the Corporation or its Subsidiaries for any reason other than his or her death, such Optionee shall have the right, subject to the restrictions of Subsection (e) hereof, to exercise the Option either: 
  
 (i) at any time within three (3) months after such
termination of employment; or 
  
 (ii) (in the
case of Early, Normal or Late Retirement under the Salaried Employees’ Retirement Plan, or Disability), at any time before the end of the option period specified in the Option Agreement, 
  
 to the extent that, at the date of termination of employment, the Optionee’s right to
exercise such Option had accrued pursuant to the terms of the Option Agreement with respect to which such option was granted and had not previously been exercised; provided, however, that if the employment of an Optionee is terminated by the
Corporation or a Subsidiary by reason of misconduct, such Option shall cease to be exercisable at the time of the Optionee’s termination of employment. As used herein “misconduct” means that the Optionee has engaged in unfair
competition with the Corporation or a Subsidiary, induced any customer of the Corporation or a Subsidiary to breach any contract with the Corporation or a Subsidiary, made any unauthorized disclosure of any of the secrets or confidential information
of the Corporation or a Subsidiary, committed an act of embezzlement, fraud or theft with respect to the property of the Corporation or a Subsidiary, or engaged in conduct which is not in good faith and which directly results in material loss,
damage or injury to the business, reputation or employees of the Corporation or a Subsidiary. The Committee shall 

  

 12 








 
determine whether an Optionee’s employment is terminated by reason of misconduct. In making such determination the Committee shall act fairly and shall
give the Optionee an opportunity to be heard and present evidence on his or her behalf. 
  
 For this purpose, the employment relationship will be treated as continuing intact while the Optionee is on military leave, sick leave or other bona fide leave of absence (to be determined in the sole discretion of
the Committee, in accordance with rules and regulations construing Code section 422A(a)(2)). Notwithstanding the foregoing, in the case of an Incentive Stock Option, employment shall not be deemed to continue beyond the ninetieth (90th) day
after the Optionee ceased active employment, unless the Optionee’s reemployment rights are guaranteed by statute or by contract. 
  
 (g) Death of Optionee. 
  
 Except as provided in Subsection (k) below, if the Optionee shall die while in the employ of the Corporation or a Subsidiary and shall not have fully
exercised the Option, an Option may be exercised at any time before the end of the option period specified in the Option Agreement by the executors or administrators of the Optionee’s estate or by any person or persons who shall have acquired
the Option directly from the Optionee by bequest or inheritance, to the extent that, at the date of the Optionee’s death, the Optionee’s right to exercise such Option had accrued pursuant to the terms of the Option Agreement and had not
previously been exercised. 
  
 (h) Rights as a Stockholder.

  
 An Optionee or a transferee of an Optionee shall have no
rights as a stockholder with respect to any Shares covered by his or her Option until the date of the issuance of a stock certificate for such Shares. No adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities
or other property) or distributions or other rights for which the record date is prior to the date such stock certificate is issued, except as provided in Section 11. 
  

 13 








 (i) Modification, Extension and Renewal of Options. 
  
 Subject to the terms and conditions and within the limitations of the Plan,
the Committee may modify, extend or renew outstanding Options granted under the Plan, or accept the exchange of outstanding Options (to the extent not theretofore exercised) for the granting of new Options (at the same or a different price) in
substitution therefor. Notwithstanding the foregoing, however, no modification of an Option shall, without the consent of the Optionee, alter or impair any rights or obligations under any Option theretofore granted under the Plan. 
  
 (j) Stock Appreciation Rights. 
  
 In connection with the grant of any Option pursuant to the Plan, the
Committee, in accordance with its Rules, may also grant a stock appreciation right pursuant to which the Optionee shall have the right to surrender all or part of such Option and to exercise the stock appreciation right (the “call”) and
thereby to obtain payment of an amount equal to the difference obtained by subtracting the aggregate Exercise Price of the Shares subject to the Option (or the portion thereof) so surrendered from the Fair Market Value of such Shares on the date of
such surrender. In the case of a stock appreciation right called after an event described in Section 7(e)(i) or (iv) above, “Fair Market Value” for purposes of this Subsection (j) shall be the greater of (A) the Fair
Market Value of such Shares as of the date immediately prior to the event described in Section 7(e)(i) or (iv) above, or (B) the value of such Shares determined as of the date of the call in good faith by the Committee (as composed on
the day preceding the date of the event described in Section 7(e)(i) or (iv) above), taking into consideration all relevant facts and circumstances. The call of such stock 

  

 14 








 
appreciation right shall be subject to such limitations (including, but not limited to, limitations as to time and amount) as the Committee shall deem
appropriate. The payment may be made in shares of Common Stock (determined with reference to its Fair Market Value on the date of call), or in cash, or partly in cash and in shares of Common Stock, at the discretion of the Committee, provided that
the Committee determines that such settlement is consistent with the purpose set forth in Section 1 hereof. For all purposes under the Plan, the terms “exercise” or “exercisable” shall be deemed to include the terms
“call” or “callable” as such terms may apply to a stock appreciation right granted in conjunction with an Option, and in the event of the call of a stock appreciation right, the underlying Option will be deemed to have been
exercised for all purposes under the Plan. 
  
 (k) Effect of
Termination of Employment on Stock Appreciation Right. 
  
 In
the event that an Optionee shall cease to be employed by the Corporation or its Subsidiaries for any reason, any stock appreciation right which may have been granted in conjunction with the grant of an Option shall expire on the date provided in the
Option Agreement or in rules and regulations adopted by the Committee. 
  
 (l) Limitation of Annual Awards. 
  
 The aggregate
Fair Market Value (determined as of the date the Option is granted) of the stock with respect to which any Incentive Stock Options are exercisable for the first time by an Optionee during any calendar year commencing after December 31, 1986
under this Plan and all other plans maintained by the Corporation, its parent or its Subsidiaries shall not exceed $100,000. 
  

 15 








 (m) Other Provisions. 
  
 The Option Agreements authorized under the Plan shall contain such other provisions not inconsistent with the terms of the
Plan, including, without limitation, restrictions upon the exercise of the Option, as the Committee shall deem advisable. 
  

	 	8.	RESTRICTED STOCK. 

  
 (a) Grants. 
  
 Subject to the provisions of the Plan, the Committee shall have sole and complete authority to determine the persons to whom, and the time or times at
which, grants of Restricted Stock will be made, the number of shares of Restricted Stock to be awarded, the price (if any) to be paid by the recipient of Restricted Stock, the time or times within which such Awards may be subject to forfeiture, and
all other terms and conditions of the Awards. The Committee may condition the grant of Restricted Stock upon the attainment of specified performance goals or such other factors as the Committee may determine, in its sole discretion. 
  
 The terms of each Restricted Stock Award shall be set forth in a Restricted
Stock Agreement between the Corporation and the Employee, which Agreement shall contain such provisions as the Committee determines to be necessary or appropriate to carry out the intent of the Plan with respect to such Award. Each Participant
receiving a Restricted Stock Award shall be issued a stock certificate in respect of such shares of Restricted Stock. Such certificate shall be registered in the name of such Participant, and shall bear an appropriate legend referring to the terms,
conditions, and restrictions applicable to such Award. The Committee shall require that stock certificates evidencing such shares be held by the Company until the restrictions 

  

 16 








 
thereon shall have lapsed, and that, as a condition of any Restricted Stock Award, the Participant shall have delivered to the Company a stock power,
endorsed in blank, relating to the stock covered by such Award. 
  
 (b) Restrictions and Conditions. 
  
 The shares of
Restricted Stock awarded pursuant to this Section 8 shall be subject to the following restrictions and conditions: 
  
 (i) During a period set by the Committee commencing with the date of such Award (the “Restriction Period”), the Participant
shall not be permitted to sell, transfer, pledge, assign or encumber shares of Restricted Stock awarded under the Plan. Within these limits, the Committee, in its sole discretion, may provide for the lapse of such restrictions in installments and
may accelerate or waive such restrictions in whole or in part, based on service, performance, a change of control of the Corporation and/or such other factors or criteria as the Committee may determine in its sole discretion. 
  
 (ii) Except as provided in this paragraph (ii) and
paragraph (i) above, the Participant shall have, with respect to the shares of Restricted Stock, all of the rights of a shareholder of the Corporation, including the right to vote the shares, and the right to receive any cash dividends. The
Committee, in its sole discretion, as determined at the time of Award, may provide that the payment of cash dividends shall or may be deferred and, if the Committee so determines, reinvested in additional Shares of Restricted Stock to the extent
available under Section 6, or otherwise reinvested. Stock dividends issued with respect to Restricted Stock shall be treated as additional shares of Restricted Stock that 

  

 17 








 
are subject to the same restrictions and other terms and conditions that apply to the shares with respect to which such dividends are issued. 
  
 (iii) The Committee shall specify the conditions under which
shares of Restricted Stock shall vest or be forfeited and such conditions shall be set forth in the Restricted Stock Agreement. 
  
 (iv) If and when the Restriction Period applicable to shares of Restricted Stock expires without a prior forfeiture of the Restricted
Stock, certificates for an appropriate number of unrestricted Shares shall be delivered promptly to the Participant, and the certificates for the shares of Restricted Stock shall be cancelled. 
  

	 	9.	OTHER SHARE-BASED AWARDS. 

  
 (a) Grants. 
  
 Other Awards of Shares and other Awards that are valued in whole or in part by reference to, or are otherwise based on, Shares (“Other Share-Based
Awards”), may be granted either alone or in addition to or in conjunction with other Awards under this Plan. Awards under this Section 9 may include, but are not limited to, Stock Rights, stock appreciation rights not granted in connection
with the grant of any Option pursuant to Section 7, the grant of Shares conditioned upon some specified event, the payment of cash based upon the performance of the Shares or the grant of securities convertible into Shares. 
  
 Subject to the provisions of the Plan, the Committee shall have sole and
complete authority to determine the persons to whom and the time or times at which Other Share-Based Awards shall be made, the number of Shares or other securities, if 

  

 18 








 
any, to be granted pursuant to Other Share-Based Awards, and all other conditions of the Other Share-Based Awards. In making an Other Share-Based Award, the
Committee may determine that the recipient of an Other Share-Based Award shall be entitled to receive, currently or on a deferred basis, interest or dividends or dividend equivalents with respect to the Shares or other securities covered by the
Award, and the Committee may provide that such amounts (if any) shall be deemed to have been reinvested in additional Shares or otherwise reinvested. The terms of any Other Share-Based Award shall be set forth in an Other Share-Based Award Agreement
between the Corporation and the Employee, which Agreement shall contain such provisions as the Committee determines to be necessary or appropriate to carry out the intent of the Plan with respect to such Award. 
  
 (b) Terms and Conditions. 
  
 In addition to the terms and conditions specified in the Other Share-Based
Award Agreement, Other Share-Based Awards made pursuant to this Section 9 shall be subject to the following: 
  
 (i) Any Other Share-Based Award may not be sold, assigned, transferred, pledged or otherwise encumbered prior to the date on which the
Shares are issued or the Award becomes payable, or, if later, the date on which any applicable restriction, performance or deferral period lapses. 
  
 (ii) The Other Share-Based Award Agreement shall contain provisions dealing with the disposition of such Award in the event of a
termination of the Employee’s employment prior to the exercise, realization or payment of such Award, and the Committee in its sole discretion, may provide for payment of the 

  

 19 








 
Award in the event of the Employee’s retirement, Disability or death or the change of control of the Corporation, with such provisions to take account
of the specific nature and purpose of the Award. 
  

	 	10.	TERM OF PLAN. 

  
 Awards may be granted pursuant to the Plan until the termination of the Plan on December 31, 1998. 
  

	 	11.	RECAPITALIZATION. 

  
 Subject to any required action by the stockholders, the number of Shares covered by this Plan as provided in Section 6, the number of Shares covered
by or referenced in each outstanding Award, and the Exercise Price of each outstanding Option and any price required to be paid for Restricted Stock or Other Share-Based Award shall be proportionately adjusted for any increase or decrease in the
number of issued Shares resulting from a subdivision or consolidation of Shares, the payment of a stock dividend (but only of Common Stock) or any other increase or decrease in the number of such Shares effected without receipt of consideration by
the Corporation or the declaration of a dividend payable in cash that has a material effect on the price of issued Shares. 
  
 Subject to any required action by the stockholders, if the Corporation shall be a party to any merger, consolidation or other reorganization, each
outstanding Award shall pertain and apply to the securities to which a holder of the number of Shares subject to the Award would have been entitled. 
  
 In the event of a change in the Common Stock as presently constituted, 

  

 20 








 
which is limited to a change of all of its authorized shares with par value into the same number of shares with a different par value or without par value,
the shares resulting from any such change shall be deemed to be the Common Stock within the meaning of the Plan. 
  
 To the extent that the foregoing adjustments relate to stock or securities of the Corporation, such adjustments shall be made by the Committee, whose
determination in that respect shall be final, binding and conclusive, provided that each Incentive Stock Option granted pursuant to this Plan shall not be adjusted in a manner that causes the Option to fail to continue to qualify as an incentive
stock option within the meaning of section 422 of the Code. 
  
 Except as hereinbefore expressly provided in this Section 11, a Participant shall have no rights by reason of any subdivision or consolidation of shares of stock of any class or the payment of any stock dividend or any other increase
or decrease in the number of shares of stock of any class or by reason of any dissolution, liquidation, merger or consolidation or spin-off of assets or stock of another Corporation, and any issue by the Corporation of shares of stock of any class
or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to the Option. 
  
 The grant of an Option pursuant to the Plan shall not affect in any way the
right or power of the Corporation to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge or 

  

 21 








 
consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets. 
  

	 	12.	SECURITIES LAW REQUIREMENTS AND LIMITATION OF RIGHTS. 

  
 (a) Securities Law. No Shares shall be issued pursuant to the Plan unless and until the Corporation has determined that: (i) it and the
Participant have taken all actions required to register the Shares under the Securities Act of 1933 or perfect an exemption from the registration requirements thereof; (ii) any applicable listing requirement of any stock exchange on which the
Common Stock is listed has been satisfied; and (iii) any other applicable provision of state or federal law has been satisfied. 
  
 (b) Employment Rights. Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a right to remain employed by
the Corporation or a Subsidiary. The Corporation and its Subsidiaries reserve the right to terminate the employment of any employee at any time, with or without cause, subject only to a written employment contract (if any). 
  
 (c) Shareholders’ Rights. A Participant shall have no dividend
rights, voting rights or other rights as a shareholder with respect to any Shares covered by his or her Award prior to the issuance of a stock certificate for such Shares. No adjustment shall be made for cash dividends or other rights for which the
record date is prior to the date when such certificate is issued. 
  
 (d) Creditors’ Rights. A holder of an Other Share-Based Award shall have no rights other than those of a general creditor of the Corporation. An Other 

  

 22 








 
Share-Based Award shall represent an unfunded and unsecured obligation of the Corporation, subject to the terms and conditions of the applicable Other
Share-Based Award Agreement.
