3.     	
Not An Incentive Stock Option. This Option is not intended to be an “incentive stock option” within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”) and this Agreement shall be construed and interpreted in accordance with such intention.

  
	 
	
4.	
Vesting. Except as otherwise provided below, the Option shall vest and become exercisable as to the percentage of Shares
subject to the Option on the vesting dates set forth above (the “Vesting Dates”).

  
	 
	 	
(a)     	
Termination. (i) Unless the Optionee’s employment is terminated for one of the reasons set forth in Section 4(b) through (i), at the Optionee’s
termination of employment prior to the third anniversary of the date of this Agreement (but no earlier than the third month after the Grant Date), the Optionee will vest in and have the right to purchase a percentage of the Shares subject to this
Option determined by dividing (i) the number of whole months from the most recent anniversary of the Grant Date to the termination date of the Optionee’s employment by (ii) 36, and the Option will cease to be exercisable and will be cancelled
for the balance of the Shares subject to this Option. The Option shall not vest under this Section 4(a) if the Optionee’s termination of employment occurs less than three months after the Grant Date.

  
	 
	 	
(ii)	
Notwithstanding anything to the contrary
    contained herein, if the Optionee is on a leave of absence approved by the
    Corporation for medical, personal, educational and/or other permissible purposes
    pursuant  to policies of the Corporation as in effect on the date hereof,
    for a consecutive twelve-month period, such Optionee will be deemed terminated
    for purposes of this Agreement on the first anniversary of the commencement
    of such leave of absence and  this Option shall cease to vest at the end
    of such twelve-month period (with the result that the Employee shall immediately
    vest in a percentage of the Stock as provided in the Section 4(a)(i) ) and
    the Optionee will forfeit any unvested portion of  the Option); provided,
    however, that on or before the first anniversary of the commencement of the
    leave of absence, the Compensation Committee may, in its absolute discretion,
    determine to waive the application of this Section 4(a)(ii), in which  case
    the Optionee will not be deemed terminated for purposes of this Agreement
    and the Option will continue to vest in accordance with this Agreement. Notwithstanding
    the foregoing, if the Optionee’s employment is terminated pursuant to
    this Section 4(a)(ii) at the end of a medical or disability leave, then the
    Option shall cease to vest as of the end of the twelve-month leave but shall
    not be forfeited until the first anniversary of the Optionee’s termination
    of employment unless, prior to such first anniversary, the Optionee delivers
    to the Company evidence satisfactory to the Company that the Social Security
    Administration has determined that the Optionee is disabled as provided in
    Section 4(d).
  
	 
	 	
(b)	
Cause, Dereliction of Duties or Harmful Acts; Breach of Share Ownership Guidelines; Loss of Equity Award Eligibility Status. (i) If the Optionee shall cause the
Corporation to suffer financial harm or damage to its reputation (either before or after termination of employment) through (x) dishonesty, (y) violation of law in the course of the Optionee’s employment or violation of the Corporation’s
Corporate Compliance Manual and compliance bulletins or other written policies, or (z) material deviation from the duties owed the Corporation by the Optionee, this Option, whether or not vested, shall expire and be cancelled to the extent it has
not been exercised and be of no further force or effect.

  
	 
	 	 	
(ii) If the Optionee is subject to
    the Minimum Share Ownership Policy, any false attestation made under the
    Minimum Share Ownership Policy may result in the immediate cancellation of
    this Option and all Prior Options (to the extent not exercised), whether
    or not vested.

  
	 
	 	 	
(iii) If the Optionee’s employment
    status in the Corporation is changed such that the Optionee will no longer
    be eligible to receive options pursuant to the Equity Award Eligibility Policy
    of the Corporation as in effect on the date hereof and attached as Annex
    A to this Agreement and such changed status continues for  a consecutive
    90 day period, this Option shall cease to vest at the end of such 90-day
    period (and the Optionee will then vest in and have the right to purchase
    a percentage of the Shares subject to this Option determined by dividing
    (i) the number  of whole months from the most recent anniversary of the Grant
    Date to the end of such 90-day period by (ii) 36), and the Optionee will
    immediately forfeit any unvested portion of the Option. Notwithstanding the
    foregoing, this Option shall continue  to vest (and shall not be forfeited
    under this Section 4(b)(iii)) if, (x) before the end of such 90-day period,
    the Optionee has attained age 60; or (y) before the end of such 90-day period,
    the Compensation Committee, in its absolute discretion,  determines to waive
    the application of this Section 4(b)(iii).

  
	 
	 	
(c)	
Death. If the Optionee shall die while employed, this Option shall vest as to all Shares subject to the Option on the
date of the Optionee’s death.

(d)     	
Disability. If the Optionee’s employment shall terminate pursuant to Section 4(a)(ii) at the end of a medical or
disability leave and if, on or before the first anniversary of the Optionee’s termination of employment, the Optionee delivers to the Company evidence satisfactory to the Company that the Social Security Administration has determined that the
Optionee is disabled (as defined in Section 22(e)(3) of the Code),this Option shall vest as to all Shares subject to the Option on the date that such evidence is provided to the Company. .

  
	 
	 	
(e)	
Change of Control. This Option shall vest as to all shares immediately on the effective date of a change of control, provided the Optionee was actively employed
by the Corporation on such date. For purposes of this Agreement the term “change of control” shall mean and shall be deemed to occur if and when:

  
	 
	 	 	
(i)	
Any person (as such term is used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or indirectly, of securities of the Corporation
representing 40% or more of the combined voting power of the Corporation’s then outstanding securities; or

  
	 
	 	 	
(ii)     	
The individuals who, as of the Grant Date, constituted the Corporation’s Board of Directors (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board;
provided, however, that any individual (other than any individual whose initial assumption of office is in connection with an actual or threatened election contest (as such
term is used in Rule 14a-11 of Regulation A promulgated under the Securities Exchange Act of 1934)), becoming a director subsequent to the Grant Date, whose election, or nomination for election by the stockholders of the Corporation, 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 was a member of the Incumbent Board; or

  
	 
	 	 	
(iii)	
Shareholders of the Corporation approve an agreement, providing for (a) a transaction in which the Corporation will cease to be an independent publicly owned corporation, or (b) the sale or other disposition
of all or substantially all of the Corporation’s assets, or (c) a plan of partial or complete liquidation of the Corporation.

  
	 
	 	
(f)	
Involuntary Termination with Severance . If prior to the third anniversary of the date of this Agreement, the Optionee’s employment is terminated by the
Corporation and, as a result, the Optionee becomes eligible for severance benefits under one of the Corporation’s Severance Plans, the Optionee will immediately vest in and have the right to purchase a percentage of the Shares subject to this
Option determined by dividing (i) the number of whole months from the most recent anniversary of the Grant Date to the date that is twelve months after the termination date of the Optionee’s employment (or if earlier, the last Vesting Date) by
(ii) 36, and the Option will cease to be exercisable and will be cancelled for the balance of the Shares subject to this Option.

  
	 
	 	
(g)	
Divestiture. If prior to the third anniversary of the date of this Agreement, the Optionee’s employment is terminated by the Corporation due to a
divestiture and the Optionee is employed by the purchasing entity, then the Optionee will immediately vest in a percentage of the Shares subject to this Option determined by dividing (i) the number of whole months from the most recent anniversary of
the Grant Date to the date that is twelve months after the termination date of the Optionee’s employment (or if earlier, the last Vesting Date) by (ii) 36, and the Option will cease to be exercisable and will be cancelled for the balance of the
Shares subject to this Option.

  
	 
	 	
(h)	
Transfers. If
    the Optionee shall be transferred from the Corporation to a subsidiary company
    (being a 50% owned entity within the meaning of Section 424(f) of  the Code),
    or joint venture or similar entity existing as of the date of this Agreement
    in which the Corporation has at least a 33.33% interest (“joint venture”)
    or vice versa or from one subsidiary company (or joint venture) to another,
     the Optionee’s employment shall not be deemed to have terminated. If,
     while the Optionee is employed by such a subsidiary company or joint venture,
     such subsidiary company or joint venture shall cease to be a subsidiary
     company or joint venture as described above and the Optionee is not thereupon
     transferred to and employed by the Corporation or another subsidiary company
     or joint venture as described above, then the Optionee’s employment
     will be treated as a termination due to a divestiture under clause (g) above
     as of the date that the Optionee’s employer ceases to be such a subsidiary
     company or joint venture of the Corporation.

  
	 
	 	
(i)	
Retirement. If the Optionee’s employment shall terminate with the consent of the Corporation on or after the Optionee’s attaining age 60, this Option
shall vest and be exercisable as to all Shares subject to this Option on the effective termination date of the Optionee’s employment.

  
	 
	
5.     	
Non-Transferability.

  
	 
	 	
a)	
The rights under this Option Agreement shall not be transferable other than by will or the laws of descent and distribution and may be exercised during the lifetime of the Optionee only by the Optionee
except to the extent of a disability (as defined in Section 22(e)(3) of the Code), in which case the Option may be exercised by the Optionee’s legal representative.

b)	
If the Optionee is subject to the Minimum Share Ownership Policy, the Optionee agrees that any shares issued hereunder or pursuant to any Prior Option shall be subject to the restrictions set forth in the
Minimum Share Ownership Policy. If the Optionee is not in compliance with the Minimum Share Ownership Policy, the Corporation may terminate the employment of such Optionee and/or the Option shall immediately terminate and cease to be exercisable.
The Optionee hereby acknowledges and agrees that the investment risk associated with the retention of any Shares, whether pursuant to the Minimum Share Ownership Policy or otherwise, is the sole responsibility of the Optionee and Optionee hereby
holds the Corporation harmless against any claim of loss related to the retention of the Shares.

  
	 
	
6.     	
Exercise. The
    purchase price of Shares purchased hereunder shall be paid in full with,
    or in a combination of, (a) cash or (b) shares of the Corporation’s
    Common Stock that have been owned by the Optionee, and have been fully vested
    and freely transferable by the Optionee, for at least six months preceding
    the date of exercise of the Option, duly endorsed or accompanied by stock
    powers executed in blank. However, the Corporation in its discretion may
    permit the Optionee (if the Optionee owns shares that have been owned by
    the Optionee, and have been fully vested and fully transferable by the Optionee,
    for at least six months preceding the date of exercise) to “attest” to
    his ownership of the number of shares required to pay all or part of the
    purchase price (and not require delivery of the shares), in which case the
    Corporation will deliver to the Optionee the number of shares to which the
    Optionee is entitled, net of the “attested” shares. If payment
    is made in whole or in part with shares of the Corporation’s Common
    Stock, the value of such Common Stock shall be the mean between its high
    and low prices on the day of purchase as reported by The
    New York Times following the close of
    business on the date of exercise. No “reload” or other option will
    be granted by reason of any such exercise. The Optionee agrees that, notwithstanding
    the terms of any pre-existing agreement between the Corporation and the Optionee,
    any shares of the Corporation’s Common Stock surrendered (or “attested” to)
    for payment of the exercise price of any options previously granted by the
    Corporation to the Optionee (whether granted under the terms of the Amended
    and Restated Employee Long-Term Incentive Plan or any predecessor program)
    shall be valued in the manner provided in the preceding sentence except to
    the extent otherwise expressly provided by the terms of the program document.
  
	 
	
7.	
Exercise After Termination of Employment, Death or Disability. The provisions covering the exercise of this Option following termination of employment are as
follows:

  
	 
	 	
(a)     	
Termination in General. If the Optionee shall terminate his employment for any reason other than those described in Section 7(b) through (f), all of the vested
percentage of the Option may be exercised for ninety (90) days following such termination (but not beyond the Expiration Date) and the Option shall thereafter expire and cease to be exercisable;

  
	 
	 	
(b)	
Death. If the Optionee shall die while employed, the Option may be exercised through the Expiration Date in respect of all of the Shares subject to the Option.
If the Optionee shall die after termination of employment but while the Option is still exercisable, it shall remain exercisable to the same extent through the first anniversary of the date of death but not beyond the Expiration Date;

  
	 
	 	
(c)	
Disability. If the Optionee’s employment shall terminate at the end of a medical or disability leave under Section 4(a)(ii) and if, on or before the first
anniversary of the Optionee’s termination of employment, the Optionee delivers to the Company evidence satisfactory to the Company that the Social Security Administration has determined that the Optionee is disabled (as defined in Section
22(e)(3) of the Code), the Option shall remain exercisable through the Expiration Date;

  
	 
	 	
(d)	
Involuntary Termination with Severance. If the Optionee’s employment is terminated by the Corporation and, as a result, the Optionee becomes eligible for
severance benefits under the Corporation’s Severance Plans, then to the extent this Option is vested and exercisable (and becomes vested and exercisable under Section 4(f)), it may be exercised through the first anniversary of the date of
termination (but not beyond the Expiration Date) and shall thereafter expire.

  
	 
	 	
(e)	
Divestiture. If prior to the third anniversary of the date of this Agreement, the Optionee’s employment is terminated by the Corporation due to a

termination (but not beyond the Expiration Date) and shall thereafter expire.

  
	 
	 	
(f)	
Retirement. If the Optionee’s employment shall terminate as a result of Retirement as defined in Section 4(i) of this Option, all of the Option may be
exercised as to all of the Shares subject to the Option through the Expiration Date.

  
	 
	 	
In no event may any portion of the Option be exercised after the Expiration Date.

(b)	
The Optionee recognizes and acknowledges that during his or her employment with the Company, the Optionee may be given access to or develop Confidential Information. The Optionee shall not use or disclose
(directly or indirectly) any Confidential Information (whether or not developed by the Optionee) at any time or in any manner, except as authorized and required in the course of employment with the Company. The Optionee shall not disclose to the
Company or use on behalf of the Company any Confidential Information obtained from any former employer or any other third party. All documents and things embodying Confidential Information, whether prepared by the Optionee or otherwise coming into
the Optionee’s possession, are the exclusive property of the Company, and must not be removed from any of its premises except as required in the course of employment with the Company. All such documents and things shall be promptly returned by

The Optionee shall ensure that any export of Confidential Information undertaken by the Optionee or with his/her knowledge or approval shall be in compliance with all applicable laws.

  
	 
	 	
(c)	
The Optionee shall promptly disclose to the Company all Confidential Information which the Optionee creates, conceives, develops, or improves (either alone or with others) referred to below as a
“Creation” while in the employment of the Company, if the Creation either: (1) relates to any actual or demonstrably contemplated business, or research or development project, of the Company or its subsidiaries, or to any reasonable
extension or variation thereof; or (2) results from any work performed by the Optionee for the Company; or (3) was created utilizing any of the Company’s equipment, supplies, facilities, time, or Confidential Information. The Optionee shall
keep complete, accurate, and authentic records on all Creations in the manner and form requested by the Company. The Optionee shall promptly disclose to the Company, in confidence, all patent, copyright, and trademark applications filed by the
Optionee within one (1) year after termination of employment with the Company and which relate to any field in which the Optionee worked at the Company. The Optionee agrees that any such application for a patent, copyright registration, trademark
registration, mask work registration, or similar right filed within one (1) year after termination of employment with the Company shall be presumed to relate to a Creation of the Optionee created during employment at the Company, unless the Optionee
can prove otherwise.

  
	 
	 	
(d)	
The Optionee hereby assigns to the Company all of the Optionee’s rights in all of the above-described Creations. All such Creations that are subject to copyright or mask work protection are explicitly
considered by the Optionee and the Company to be works made for hire to the extent permitted by law. To the extent that any such Creations are subject to copyright protection and are not works made for hire, any and all of the Optionee’s
copyright and mask work interest therein are hereby assigned by the Optionee to the Company, and are the exclusive property of the Company.

  
	 
	 	
(e)	
The Optionee agrees to assist the Company in obtaining and/or maintaining patents, copyrights, trademarks, mask work rights, and similar rights to any Creations assigned by the Optionee to the Company, if

rights, to provide

      assignment of such Creations to the Company, to defend them from invalidation,
      and to protect them against infringement by other parties. The obligations
      of this paragraph are continuing and survive the termination of the Optionee’s
      employment with the Company. The Optionee irrevocably appoints the Chief
      Executive Officer of the Company (with powers of delegation) to act as
      the Optionee’s agent and attorney-in-fact to perform all acts as the
      Optionee’s agent and to file, prosecute, and maintain applications

transferable by the Optionee, for at least six months preceding the date of exercise) to “attest” to his ownership of the number of shares required to pay all or part of the purchase price (and not require delivery of the shares), in which
case the Corporation will deliver to the Optionee the number of shares to which the Optionee is entitled, net of the “attested” shares. If payment is made in whole or in part with shares of the Corporation’s Common Stock, the value of
such Common Stock shall be the mean between its high and low prices on the day of purchase as reported by The New York Times following the close of business on the date of
exercise. No “reload” or other option will be granted by reason of any such exercise. The Optionee agrees that, notwithstanding the terms of any pre-existing agreement between the Corporation and the Optionee, any shares of the
Corporation’s Common Stock surrendered (or “attested” to) for payment of the exercise price of any options previously granted by the Corporation to the Optionee (whether granted under the terms of the Amended and Restated Employee
Long-Term Incentive Plan or any predecessor program) shall be valued in the manner provided in the preceding sentence except to the extent otherwise expressly provided by the terms of the program document.

terms of Section 9 of this Agreement and/or (ii) the non-compete obligations set forth in any agreement between the Optionee and the Corporation or otherwise pursuant to any written policy of the Corporation, in addition to any equitable and legal
rights the Corporation has or may have. The Optionee understands that the forfeiture of any unexercised portion of the Option is only one element of the damages potentially sustained by the Corporation for a violation of Section 9 of this Agreement
or the non-compete obligation described above, and such forfeiture shall not constitute a release of any claim that the Company may have for damages, past, present, or future. In addition, a breach by the Employee of any non solicit, non compete or
confidentiality covenant or any other restrictive covenants of his or hers that may be in place that occurs after any exercise and delivery of shares pursuant to this Agreement (including any breach occurring after termination of employment) shall
cause such exercise and delivery to be rescinded (and if the Employee has previously sold the shares issued pursuant to this Agreement, the Employee would be required to pay back to the Company the pre-tax proceeds received from the sale of such
shares).

  
	 
	
12.

purchase of Shares or other rights hereunder, or the taking of any other action hereunder (a “Plan Action”), then no such Plan Action shall be taken, in whole or in part, unless and until such consent shall have been effected or obtained
to the full satisfaction of the Corporation.

  
	 
	 	
(b)	
The term “consent” as used herein with respect to any action referred to in Section 12(a) means (i) any and all listings, registrations or qualifications in respect thereof upon any securities
exchange or under any federal, state or local law, rule or regulation, (ii) any and all written agreements and representations by the Optionee with respect to the disposition of Shares, or with respect to any other matter, which the Corporation
shall deem necessary or desirable to comply with the terms of any such listing, registration or qualification or to obtain an exemption from the requirement that any such listing, qualification or registration be made, (iii) any and all consents,
clearances and approvals in respect of a Plan Action by any governmental or other regulatory bodies, and (iv) any and all consents or authorizations required to comply with, or required to be obtained under, applicable local law or otherwise
required by the Corporation. Nothing herein shall require the Corporation to list, register or qualify the Shares of its common stock on any securities exchange.

  
	 
	
13.	
Invalidity and Enforcement. If any provision of this Agreement is deemed invalid or unenforceable, either in whole or in part, this Option Agreement will be
deemed amended to delete or to modify, as set forth in this Section, the offending provision or provisions and to alter the bounds of this Agreement in order to render it valid and enforceable. The Corporation and the Optionee specifically request
that any court having jurisdiction over any dispute relating to this Option Agreement modify, if possible, any offending provision so that such provision will be enforceable to the maximum extent permitted by State law.

Agreement.

and constitutes the entire agreement between the Corporation and the Optionee. No modification of this Option Agreement will have any force or effect unless such modification is in writing, signed by the Chief Executive Officer of the Corporation
and the Optionee, and expressly indicates an intent to modify this Option Agreement.

  
	 
	
17.	
Interpretation. Any dispute, disagreement or matter of interpretation which shall arise under this Agreement shall be finally determined by the
Corporation’s Compensation Committee in its absolute discretion.

  
	 
	
18.	
Notice of Exercise. The Optionee may exercise the Option, in accordance with the procedures specified by the Corporation from time to time.
