SECTION 1.    Purpose. The purpose of this Amended and Restated 2008 Long-Term Incentive Plan (the
“Plan”) of Hess Corporation (together with any successor thereto, the “Corporation”) is (a) to promote the identity of interests between shareholders of the Corporation and non-employee directors of the Corporation and

(c) to provide meaningful long-term incentive opportunities for such officers, other employees, consultants and directors who are responsible for the success of the Corporation and the Subsidiaries and who are in a position to make significant
contributions toward their objectives.

connection with such Change of Control, with appropriate adjustments to the number and kind of securities of such surviving or successor corporation or entity, or such other applicable parent, subsidiary, corporation or entity, subject to the Award
and the exercise or purchase price thereof, which preserves the compensation element of the Award existing at the time of such Change of Control transaction, and provides for subsequent payout in accordance with the same (or more favorable) payment

in clause (i), (ii) or (iii) is directly and materially harmful to the business or reputation of the Corporation or any Subsidiary; provided further, however, that, if at any particular time the Participant is subject to an
effective employment agreement or change in control agreement with the Corporation or a Subsidiary, then, in lieu of the foregoing definition, “Cause” shall at that time have such meaning as may be specified in such employment agreement or

the following events (regardless of whether any other reason, other than Cause, for the Participant’s termination of employment exists or has occurred): (i) failure to elect or reelect or otherwise to maintain the Participant in the office

(B) without limiting the generality or effect of the foregoing, any material breach of such agreement by the Corporation or such Subsidiary, which breach is not remedied within ten (10) days after written notice to the Corporation from the
Participant describing the nature of such breach. The foregoing to the contrary notwithstanding, if at any particular time the Participant is subject to an effective employment agreement or change in control agreement with the Corporation or a
Subsidiary, then, in lieu of the foregoing definition, “Good Reason” shall at that time have such meaning as may be specified in such employment agreement or change in control agreement, as applicable.

Change of Control transaction, and provides for subsequent payout in accordance with the same (or more favorable) payment and vesting schedule applicable to such Award, as determined in accordance with the instruments evidencing the agreement to

 (i) to select and
designate Participants; 
 (ii) to designate Subsidiaries;

Award granted under the Plan (including, but not limited to, any exercise price, grant price, or purchase price, any restriction or condition, any schedule for lapse of restrictions or conditions relating to transferability or forfeiture,

determined in connection with an Award; 
 (v) to determine whether, to what extent, and under what circumstances an Award may be
settled, or the exercise price of an Award may be paid, in cash, Shares, other Awards, or other property, or an Award may be cancelled, forfeited, or surrendered; 

(vi) to determine whether, to what extent, and under what circumstances cash, Shares, other Awards, or other property payable with respect
to an Award will be deferred either automatically, at the election of the Committee, or pursuant to an agreement between the Corporation and the Participant; 

(vii) to prescribe the form of each Award Agreement, which need not be identical for each Participant;

or advisable to administer the Plan; 
 (ix) to interpret the Plan and the Award Agreements hereunder, with such interpretations to be
conclusive and binding on all persons and otherwise accorded the maximum deference permitted by law;

supply any omission or reconcile any inconsistency in the Plan and to construe and interpret the Plan and any Award, rules and regulations, Award Agreement, or other instrument hereunder; and

Committee may deem necessary or advisable for the administration of the Plan. 

  
 6 

 3.02 Manner of Exercise of Committee Authority. Unless authority is specifically
reserved to the Board under the terms of the Plan, or applicable law, the Committee shall have sole discretion in exercising such authority under the Plan. Any action of the Committee with respect to the Plan shall be final, conclusive, and binding
on all persons, including the Corporation, Subsidiaries, Participants, any person claiming any rights under the Plan from or through any Participant, and shareholders. The express grant of any specific power to the Committee, and the taking of any
action by the Committee, shall not be construed as limiting any power or authority of the Committee. The Committee may, to the extent permissible under applicable law, delegate to officers or managers of the Corporation or any Subsidiary the
authority, subject to such terms as the Committee shall determine, to perform administrative functions under the Plan. 

3.03 Limitation of Liability. Each member of the Committee shall be entitled to, in good faith, rely or act upon any report
or other information furnished to him by any officer or other employee of the Corporation or any Subsidiary, the Corporation’s independent certified public accountants, or any consultant or other professional retained by the Corporation to
assist in the administration of the Plan. No member of the Committee, nor any officer or employee of the Corporation acting on behalf of the Committee, shall be personally liable for any action, determination, or interpretation taken or made in good
faith with respect to the Plan, and all members of the Committee and any officer or employee of the Corporation acting on their behalf, shall, to the extent permitted by law, be fully indemnified and protected by the Corporation with respect to any
such action, determination, or interpretation. 
 SECTION 4.    Shares Subject to the Plan. The shares
of stock subject to Awards granted under the Plan shall be Shares. Shares subject to the Plan may be either authorized and unissued shares (which will not be subject to preemptive rights) or previously issued shares acquired by the Corporation or
any Subsidiary. Subject to adjustment as provided in Section 10, the total number of Shares reserved and available for Awards under the Plan during the term hereof shall be (a) 38,000,000 Shares, plus (b) up to 2,864,875 Shares
subject to outstanding stock options or other awards under the Hess Corporation Second Amended and Restated 1995 Long-Term Incentive Plan (the “Prior Plan”) to the extent that on or after March 24, 2015, such stock options or other
awards are forfeited or such a stock option or other award is settled or terminates without a distribution of Shares (whether or not cash, other awards or other property is distributed with respect to such stock option or other award) (the
“Share Reserve”). For purposes of this Section 4, (a) each Share delivered pursuant to an Option shall reduce the Share Reserve by one (1) Share; (b) each Share subject to the exercised portion of a SAR shall reduce the
Share Reserve by one (1) Share, such that the total number of Shares with respect to which such SAR is exercised shall reduce the Share Reserve by an equal number of Shares; (c) each Share delivered pursuant to a Restricted Stock Unit
Award, a Dividend Equivalent paid in Shares, or a Performance Award shall reduce the Share Reserve by two (2) Shares; (d) each Share delivered pursuant to a Restricted Stock Award without a purchase price, or with a per-Share purchase
price lower than one hundred percent (100%) of the Fair Market Value of a Share on the grant date of such Restricted Stock Award, shall reduce the Share Reserve by two (2) Shares; (e) each Share delivered pursuant to a Restricted
Stock Award with a per-Share purchase price at least equal to one hundred percent 

  
 7 

 
(100%) of the Fair Market Value of a Share on the grant date of such Restricted Stock Award shall reduce the Share Reserve by one (1) Share; and (f) notwithstanding the foregoing
provisions of this sentence to contrary, the Share Reserve shall not be reduced to the extent that a distribution pursuant to an Award is made in cash. Subject to the immediately preceding sentence, and except (x) as may be inconsistent with
the rules governing Incentive Stock Options under the Code and (y) for purposes of the maximum Share amounts set forth in Sections 7.02(i) and 7.02(ii), if any Shares are subject to an Option, Stock Appreciation Right, or other Award which
for any reason expires or is terminated or canceled without having been fully exercised or satisfied, or are subject to any Restricted Stock Award (including any Shares subject to a Participant’s Restricted Stock Award that are repurchased by
the Corporation at the Participant’s cost), Restricted Stock Unit Award or other Award granted under the Plan which are forfeited, the Shares subject to such Award shall, to the extent of any such expiration, termination, cancellation or
forfeiture, be available for delivery in connection with future Awards under the Plan. Notwithstanding any other provisions of this Section 4 to the contrary, (i) the payment of cash dividends or Dividend Equivalents in cash in connection
with Awards shall not reduce the Share Reserve, (ii) Shares withheld or tendered to pay the exercise price of an Option shall not again be available for issuance pursuant to future Awards under the Plan, (iii) Shares withheld or tendered
to pay withholding taxes with respect to an outstanding Award shall not again be available for issuance pursuant to future Awards under the Plan, (iv) Shares not delivered to a Participant under a stock–settled Stock Appreciation Right
(whether such Shares are withheld to cover the base price or are withheld to pay withholding taxes) shall not again be available for issuance pursuant to future Awards under the Plan, and (v) Shares repurchased by the Corporation using proceeds
from the exercise of an Option shall not again be available for issuance pursuant to future Awards under the Plan. Any Shares delivered under the Plan upon exercise or satisfaction of Substitute Awards shall not reduce the Shares available for
delivery under the Plan; provided, however, that the total number of Shares that may be delivered pursuant to Incentive Stock Options granted under the Plan shall be equal to 38,000,000 Shares, as adjusted pursuant to this
Section 4, but without application of the foregoing provisions of this sentence or the provisions of the first sentence of this Section 4 concerning Shares subject to certain stock options or other awards under the Prior Plan. From and
after the Effective Date, no further grants or awards shall be made under the Prior Plan; however, grants or awards made under the Prior Plan before the Effective Date shall continue in effect in accordance with their terms. 

SECTION 5.    Eligibility. Awards may be granted only to individuals who are officers, other employees
(including employees who are also directors) or consultants of the Corporation or a Subsidiary, or non-employee directors of the Corporation. 

SECTION 6.    Specific Terms of Awards. 

6.01 General.  Awards may be granted on the terms and conditions set forth in this Section 6. In addition, the
Committee may impose on any Award or the exercise thereof, at the date of grant or thereafter (subject to Section 11.02), such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine.
Except as provided in Section 7.04, only services may be required as consideration for the grant of any Award.

6.03 Dividend Equivalents.  The Committee is authorized to grant Dividend Equivalents to Participants. The Committee may
provide that Dividend Equivalents shall be paid or distributed when accrued or shall be deemed to have been reinvested in additional Shares or Awards, or otherwise reinvested. No Dividend Equivalents shall relate to Shares underlying an Option or
Stock Appreciation Right. 
 6.04 Restricted Stock.  The Committee is authorized to grant Restricted Stock to
Participants on the following terms and conditions: 
 (i) Issuance and Restrictions. 

(a) Restricted Stock (other than Special Restricted Stock) shall be subject to such restrictions on transferability and other restrictions
as the Committee may impose (including, without limitation, limitations on the right to vote such Restricted Stock or the right to receive dividends thereon), which restrictions shall lapse: (x) in full with respect to all Shares underlying
such Award of Restricted Stock at the expiration of a period not less than three years from the date of grant of such Award; (y) proportionally in equal installments of the Shares underlying such Award of Restricted Stock over a period not less
than three years from the date of grant of such Award; or (z) in the case of Performance-Based Restricted Stock, a performance period of not less than one year with respect to which it is to be determined whether the performance goals
applicable to such Performance-Based Restricted Stock have been achieved, as the Committee shall determine, except that such restrictions may lapse earlier in the event of death, disability or retirement of an awardee, on such terms as the Committee
shall determine, or in accordance with Section 9 hereof. The Committee shall not have the authority to otherwise accelerate the vesting of an Award of Restricted Stock under this Section 6.04(i)(a). 

(b) Special Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may impose
(including, without limitation, limitations on the right to vote Special Restricted Stock or the right to receive dividends thereon) which 

  
 9 

 
restrictions may lapse separately or in combination at such times, under such circumstances, in such installments, or otherwise, as the Committee shall determine. 

(ii) Forfeiture.  Performance-Based Restricted Stock shall be forfeited unless preestablished performance goals specified
by the Committee are met during the applicable restriction period. Except as otherwise determined by the Committee, upon termination of employment (as determined under criteria established by the Committee) during the applicable restriction period,
Restricted Stock that is at that time subject to restrictions shall be forfeited and returned to the Corporation. 

(iii) Certificates of Shares.  Restricted Stock granted under the Plan may be evidenced in such manner as the Committee
shall determine. If certificates representing Restricted Stock are registered in the name of the Participant, such certificates shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted
Stock, the Corporation or an escrow agent acting on behalf of the Corporation shall retain physical possession of the certificates, and the Participant shall deliver a stock power to the Corporation or such agent, endorsed in blank, relating to the
Restricted Stock. 
 (iv) Dividends.  Unless otherwise determined by the Committee, cash dividends and other
distributions made or paid with respect to the Shares underlying an Award of Restricted Stock or Performance-Based Restricted Stock shall be held in escrow, and may (but need not be) reinvested as determined by the Committee. Such dividends and
other distributions shall be paid to the Participant, together with interest or other earnings thereon (if any), at the time the Shares are delivered to the Participant. Shares distributed in connection with a stock split or stock dividend, and
other property distributed as a dividend or other distribution, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock or Performance-Based Restricted Stock with respect to which such stock or other
property has been distributed.

Units to Participants, on the following terms and conditions: 
 (i) Award and Restrictions. 

(a) Settlement of an Award of Restricted Stock Units by delivery of Shares, a cash payment, or a combination thereof will occur upon

such restriction period may lapse earlier in the event of death, disability or retirement of an awardee, on such terms as the Committee shall determine, or in accordance with Section 9 

  
 10 

 
hereof. In addition, Restricted Stock Units shall be subject to such other restrictions as the Committee may impose, which other restrictions shall lapse at the expiration of such restriction

Units, shall be determined by the Committee, after taking into account, without limitation, the provisions of Section 409A of the Code.

Section 422 of the Code); provided further, however, that Substitute Awards granted in the form of Options shall have an exercise price per Share that is intended to maintain the economic value of the award that was replaced, as
determined by the Committee. On and after the date of grant of an Option hereunder, the Committee shall not have the authority to amend such Option to reduce the exercise price thereof, except as provided in Section 10.

respect to any such form of payment, and the methods by which Shares will be delivered or deemed to be delivered to Participants. Options shall expire not later than ten years after the date of grant. 

  
 11 

 (iii) Incentive Stock Options. 

(a) General. The terms of any Incentive Stock Option granted under the Plan shall comply in all respects with the provisions
of Section 422 of the Code, including, but not limited to the requirement that no Incentive Stock Option shall be granted on or after May 7, 2018. No Incentive Stock Option shall be granted to any individual otherwise eligible to participate in
the Plan who is not an employee of the Corporation or a Subsidiary on the date of granting of such Option. Any Incentive Stock Option granted under the Plan shall contain such terms and conditions, consistent with the Plan, as the Committee may
determine to be necessary to qualify such Option as an “incentive stock option” under Section 422 of the Code. Any Incentive Stock Option granted under the Plan may be modified by the Committee to disqualify such Option from treatment
as an “incentive stock option” under Section 422 of the Code. 
 (b) $100,000 Per Year
Limitation. Notwithstanding any intent to grant Incentive Stock Options, an Option granted under the Plan will not be considered an Incentive Stock Option to the extent that it, together with any other “incentive stock options”
(within the meaning of Section 422 of the Code, but without regard to subsection (d) of such Section) under the Plan and any other “incentive stock option” plans of the Corporation, any Subsidiary and any “parent
corporation” of the Corporation within the meaning of Section 424(e) of the Code, are exercisable for the first time by any Participant during any calendar year with respect to Shares having an aggregate Fair Market Value in excess of
$100,000 (or such other limit as may be required by the Code) as of the time the Option with respect to such Shares is granted. The rule set forth in the preceding sentence shall be applied by taking Options into account in the order in which they
were granted. 
 (c) Options Granted to Certain Stockholders. No Incentive Stock Option shall be granted to an individual
otherwise eligible to participate in the Plan who owns (within the meaning of Section 424(d) of the Code), at the time the Option is granted, more than ten percent (10%) of the total combined voting power of all classes of stock of the
Corporation or a Subsidiary or any “parent corporation” of the Corporation within the meaning of Section 424(e) of the Code. This restriction does not apply if at the time such Incentive Stock Option is granted the exercise price of
the Incentive Stock Option is at least 110% of the Fair Market Value of a Share on the date such Incentive Stock Option is granted, and the Incentive Stock Option by its terms is not exercisable after the expiration of five years from such date of
grant. 
 (d) Disqualifying Disposition. If Shares acquired upon exercise of an Incentive Stock Option are disposed of in a
disqualifying disposition within the meaning of Section 422 of the Code by a Participant prior to the expiration of either two years from the date of grant of such Option or one year from the transfer of Shares to the Participant pursuant to
the exercise of such Option, or in any other disqualifying disposition within the meaning of Section 422 of the Code, such Participant shall notify the Corporation in writing as soon as practicable thereafter of the date and terms of such
disposition and, if the Corporation (or any affiliate thereof) thereupon has a tax-withholding obligation, shall pay to the Corporation (or such affiliate) an amount equal to any withholding tax the Corporation (or affiliate) is required to pay as a
result of the disqualifying disposition. 

  
 12 

 6.07 Stock Appreciation Rights. The Committee is authorized to grant Stock
Appreciation Rights to Participants on the following terms and conditions: 
 (i) Right to Payment. A Stock Appreciation
Right shall confer on the Participant to whom it is granted a right to receive, upon exercise thereof, the excess of (A) the Fair Market Value of one Share on the date of exercise over (B) the base price of the Stock Appreciation Right as
determined by the Committee as of the date of grant of the Stock Appreciation Right, which shall be not less than the Fair Market Value of one Share on the date of grant (provided, however, that Substitute Awards granted in the form of
Stock Appreciation Rights shall have a base price per Share that is intended to maintain the economic value of the award that was replaced, as determined by the Committee). On and after the date of grant of a Stock Appreciation Right hereunder, the
Committee shall not have the authority to reduce the base price of such Stock Appreciation Right, except as provided in Section 10 hereof. 

(ii) Other Terms. The Committee shall determine the time or times at which a Stock Appreciation Right may be exercised in
whole or in part, the method of exercise, method of settlement, form of consideration payable in settlement, method by which Shares will be delivered or deemed to be delivered to Participants, and any other terms and conditions of any Stock
Appreciation Right. Stock Appreciation Rights shall expire not later than ten years after the date of grant. 

SECTION 7.    Certain Provisions Applicable to Awards. 

7.01 Performance-Based Awards. To the extent an exception from the deduction limitations of Section 162(m) of the Code is
sought, Performance Awards, Performance-Based Restricted Stock and Performance-Based Restricted Stock Units granted to Covered Employees, are intended to be “qualified performance-based compensation” within the meaning of
Section 162(m) of the Code and shall be paid solely on account of the attainment of one or more preestablished, objective performance goals within the meaning of Section 162(m) and the regulations thereunder. The performance goal shall be
the attainment of preestablished levels of net income, earnings, reserve replacement, cash flow, net cash flow from operations, sales, production, cost of production, margins, capital expenditures, market capitalization, market price per share,
return on equity, return on assets, return on capital employed, earnings per share, net asset value, book value per share or total shareholder return, as determined by the Committee. Such performance goals may be applied either individually,
alternatively or in any combination to the Corporation or any Subsidiary or Subsidiaries, on a consolidated or individual company basis, or on a division, entity, line of business, project or geographical basis, either individually, alternatively or
in any combination, as determined by the Committee, in its discretion. As determined by the Committee, performance goals may relate to absolute performance or relative performance compared to the performance of other companies, an index or indices
or other comparator selected by the Committee in its discretion consistent with the “qualified performance-based compensation” exception under Section 162(m) of the Code. The Committee may provide in advance for such adjustments to
any performance goal as it may determine are permitted under Section 162(m) of the Code. 
 The payout of any such Award to a Covered
Employee may be reduced, but not increased, based on the degree of attainment of other performance criteria or otherwise at the discretion of the Committee. 

  
 13 

 7.02 Maximum Awards.  The maximum Share amounts in this Section 7.02
are subject to adjustment under Section 10 and are subject to the Plan maximum under Section 4. 
 (i) Performance-Based
Awards.  The maximum aggregate amount awarded in respect of Performance Awards, Performance-Based Restricted Stock and Performance-Based Restricted Stock Units in any Year may not exceed 375,000 Shares, or the equivalent Fair
Market Value thereof on the award date (whether or not such Award is denominated in cash, Shares, Share equivalents or units), in the case of any individual Participant. 

(ii) Stock Options and SARs.  Each individual Participant may not receive in any Year Awards of Options or Stock
Appreciation Rights exceeding 750,000 Shares. 
 (iii) Special Restricted Stock and Special Restricted Stock
Units.  A maximum of 650,000 Shares may be made subject to Awards of Special Restricted Stock and Special Restricted Stock Units, in the aggregate, under the Plan during the term hereof. 

7.03 Stand-Alone, Additional, Tandem, and Substitute Awards.  Awards granted under the Plan may, in the discretion of the
Committee, be granted either alone or in addition to or in tandem with any other Award granted under the Plan or any award granted under any other plan of the Corporation, any Subsidiary, or any business entity to be acquired by the Corporation or a
Subsidiary, or any other right of a Participant to receive payment from the Corporation or any Subsidiary. No Award may be granted in substitution for any other Award theretofore granted under the Plan, and no Award may be retroactively granted in
tandem with any other Award theretofore granted under the Plan, at an exercise or base price less than that of such other previously granted Award, without, in each such case, first obtaining approval of the shareholders of the Corporation of such
action; provided, however, that the Committee may, in its discretion, grant Awards or Shares (“Substitute Awards”) in assumption of, or in substitution or exchange for, options or other awards previously granted, or the right
or obligation to grant future options or other awards, by a business entity acquired or to be acquired by the Corporation or a Subsidiary or with which the Corporation or a Subsidiary combines, or otherwise in connection with any merger,
consolidation, acquisition of property or stock, or reorganization involving the Corporation or a Subsidiary, including a transaction described in Section 424(a) of the Code. 

7.04 Term of Awards.  The term of each Award shall be for such period as may be determined by the Committee;
provided, however, that (i) in no event shall the term of any Option or a Stock Appreciation Right exceed a period of ten (10) years from the date of its grant (or such shorter period as may be required under Section 422
of the Code) and; (ii) notwithstanding any contrary provision of the Plan, an Agreement may provide that the period of time over which a Non-Qualified Stock Option may be exercised shall be automatically extended if on the scheduled expiration
date of such Option the Participant’s exercise of such Option would violate applicable laws, in which case (A) during such extended exercise period the Option may only be exercised to the extent the Option was exercisable in accordance
with its terms immediately prior to such scheduled expiration date; and (B) such extended exercise period shall end not later than thirty (30) days after the exercise of such Option first would no longer violate such laws. 

  
 14 

 7.05 Form of Payment Under Awards.  Subject to the terms of the Plan and
any applicable Award Agreement, payments to be made by the Corporation or a Subsidiary upon the grant or exercise of an Award may be made in such forms as the Committee shall determine, including without limitation, cash, Shares, other Awards, or
other property, and may be made in a single payment or transfer, in installments, or on a deferred basis. Such payments may include, without limitation, provisions for the payment or crediting of reasonable interest on installment or deferred
payments or the grant or crediting of Dividend Equivalents in respect of installment or deferred payments denominated in Shares. 

SECTION 8.    General Restrictions Applicable to Awards. 

8.01 Restrictions Under Rule 16b-3; Nontransferability. 

(i) Nontransferability.  Awards which constitute derivative securities (including any Option, Stock Appreciation Right,
or similar right) shall not be transferable by a Participant except (i) upon such terms and conditions and subject to such limitations, as the Committee may determine, to an Immediate Family Member of such Participant, or to a trust,
partnership or limited liability company all of whose beneficiaries, partners or members, as the case may be, are Immediate Family Members or to another transferee permitted by the Committee (provided, however, that no Award may be
transferred for value or other consideration without first obtaining approval thereof by the shareholders of the Corporation); (ii) by will or the laws of descent and distribution (or pursuant to a beneficiary designation authorized under
Section 8.02) or (iii) if then permitted under Rule 16b-3, pursuant to a qualified domestic relations order as defined under the Code or Title I of the Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder; provided, however, that Incentive Stock Options and any Stock Appreciation Rights related to Incentive Stock Options, or, if then required by Rule 16b-3, any other derivative security, granted to a Participant under
the Plan, shall be exercisable during the lifetime of such Participant only by such Participant. 
 (ii) Compliance with
Rule 16b-3.  It is the intent of the Corporation that this Plan comply in all respects with Rule 16b-3 in connection with any Award granted to a person who is subject to Section 16 of the Exchange Act. Accordingly, if
any provision of this Plan or any Award Agreement does not comply with the requirements of Rule 16b-3 as then applicable to any such person, such provision shall be construed or deemed amended to the extent necessary to conform to such
requirements with respect to such person. 
 8.02 Limits on Transfer of Awards; Beneficiaries.  Except as provided in
Section 8.01, no right or interest of a Participant in any Award shall be pledged, encumbered or hypothecated to or in favor of any party (other than the Corporation or a Subsidiary), or shall be subject to any lien, obligation, or liability of
such Participant to any party (other than the Corporation or a Subsidiary). Unless otherwise determined by the Committee (subject to the requirements of Section 8.01(i)), no Award subject to any restriction shall be assignable or transferable
by a Participant otherwise than by will or the laws of descent and distribution (except to the Corporation under the terms of the Plan); provided, however, that a Participant may, in the manner established by the Committee, designate a
beneficiary or beneficiaries to exercise the rights of the Participant, and to receive any distribution, with respect to any Award, upon the death of the Participant. A beneficiary, guardian, legal representative, or other person claiming

  
 15 

 
any rights under the Plan from or through any Participant shall be subject to all terms and conditions of the Plan and any Award Agreement applicable to such Participant or Agreement applicable
to such, except to the extent the Plan and such Award Agreement or agreement otherwise provide with respect to such persons, and to any additional restrictions deemed necessary or appropriate by the Committee. 

8.03 Requirements of Law; Registration and Listing Compliance. 

(i) The Corporation shall not be obligated to deliver any Award or distribute any Shares with respect to any Award in a transaction
subject to regulatory approval, registration, or any other applicable requirement of federal or state or other law, regulation or rule, or subject to a listing requirement under any listing or similar agreement between the Corporation and any
national securities exchange, until such laws, regulations, rules and contractual obligations of the Corporation have been complied with in full, although the Corporation shall be obligated to use its best efforts to obtain any such approval and
comply with such requirements as promptly as practicable. 
 (ii) If at any time counsel to the Corporation shall be of the opinion that
any sale or delivery of Shares pursuant to an Award is or may be in the circumstances unlawful or result in the imposition of excise taxes on the Corporation or any Subsidiary under the statutes, rules or regulations of any applicable jurisdiction,
the Corporation shall have no obligation to make such sale or delivery, or to make any application or to effect or to maintain any qualification or registration under the Securities Act of 1933, as amended, or otherwise with respect to Shares or
Awards and the right to exercise or payment of any Option or Award shall be suspended until, in the opinion of such counsel, such sale or delivery shall be lawful or will not result in the imposition of excise taxes on the Corporation or any
Subsidiary. This Section 8.03(ii) shall be applied by the Committee after taking into account, without limitation, the possible application of Section 409A of the Code, as the Committee may deem appropriate. 

(iii) Upon termination of any period of suspension under this Section 8.03, any Award affected by such suspension which shall not
then have expired or terminated shall be reinstated as to all Shares available before such suspension and as to the Shares which would otherwise have become available during the period of such suspension, but no suspension shall extend the term of
any Award. 
 8.04 Share Certificates.  All certificates for Shares delivered under the Plan pursuant to any Award or
the exercise thereof shall be subject to such stop-transfer order and other restrictions as the Committee may deem advisable under applicable federal or state laws, rules and regulations thereunder, and the rules of any national securities exchange
on which Shares are listed. The Committee may require each person receiving Shares in connection with any Award under the Plan to represent and agree with the Corporation in writing that such person is acquiring such Shares for investment without a
view to the distribution thereof, and provide such other representations and agreements as the Committee may prescribe. The Committee, in its absolute discretion, may impose such restrictions on the ownership and transferability of the Shares
purchasable or otherwise receivable by any person under any Award as it deems appropriate. The Committee may cause a legend or legends to be placed on any such 

  
 16 

 
certificates to make appropriate reference to such restrictions or any other restrictions that may be applicable to Shares, including under the terms of the Plan or any Award Agreement. In
addition, during any period in which Awards or Shares are subject to restrictions under the terms of the Plan or any Award Agreement, or during any period during which delivery or receipt of an Award or Shares has been deferred by the Committee or a
Participant, the Committee may require the Participant to enter into an agreement providing that certificates representing Shares issuable or issued pursuant to an Award shall remain in the physical custody of the Corporation or such other person as
the Committee may designate. 
 SECTION 9.    Change of Control Provisions. Notwithstanding any other
provision of the Plan, the following acceleration and valuation provisions of this Section 9 shall apply in the event of a “Change of Control” as defined in Section 9. 

9.01 Acceleration and Cash-Out.  In the event of a Change of Control, unless otherwise specifically prohibited by any
applicable laws, rules or regulations or otherwise provided in any applicable Award Agreement, as in effect prior to the occurrence of the Change of Control: 

(i) In its sole discretion, and on such terms and conditions as it deems appropriate, the Committee may provide, either by the terms of the
Award Agreement or by resolution adopted prior to the occurrence of such Change of Control, that the target performance goals of any Performance Awards, Performance-Based Restricted Stock, Performance-Based Restricted Stock Units shall be deemed
fully or partially achieved and such Awards shall be fully or partially earned and vested, subject only to the restrictions on dispositions of equity securities set forth in Section 8.01(ii) and legal restrictions on the issuance of Shares set
forth in Sections 8.03 and 8.04; provided, however, that, if (i) any such Awards are not Assumed or Replaced, or in the event of a liquidation of the Corporation, or (ii) a Participant’s employment is terminated either
by the Corporation or a Subsidiary without Cause or by the Participant for Good Reason, within twenty-four (24) months after the Change of Control, then, with respect to any such Awards that (x) are not so Assumed or Replaced, or are
outstanding at the time of such a liquidation of the Corporation, or (y) are held by a Participant whose employment is so terminated, as the case may be, the target performance goals of any such Performance Award, Performance-Based Restricted
Stock and Performance-Based Restricted Stock Units shall be deemed fully achieved and all such Awards shall be fully earned and vested, subject only to the restrictions on dispositions of equity securities set forth in Section 8.01(ii) and
legal restrictions on the issuance of Shares set forth in Sections 8.03 and 8.04; 
 (ii) In its sole discretion, and on such terms and
conditions as it deems appropriate, the Committee may provide, either by the terms of the Award Agreement or by resolution adopted prior to the occurrence of such Change of Control, that any Option, Stock Appreciation Right, and other Award in the
nature of a right that may be exercised which was not previously exercisable and vested shall become exercisable and vested as determined by the Committee, subject only to the restrictions on disposition of equity securities set forth in
Section 8.01(ii) and legal restrictions on the issuance of Shares set forth in Sections 8.03 and 8.04; provided, however, that if (i) any such Options, Stock Appreciation Rights or other Awards are not Assumed or Replaced, or
in the event of a liquidation of the Corporation, or (ii) a Participant’s employment is terminated either by the Corporation or a Subsidiary without Cause or by the 

  
 17 

 
Participant for Good Reason, within twenty-four (24) months after the Change of Control, then all outstanding Options, Stock Appreciation Rights and such other Awards (if applicable) that
(x) are not so Assumed or Replaced, or are outstanding at the time of such a liquidation of the Corporation, or (y) are held by a Participant whose employment is so terminated, as the case may be, which were not previously exercisable and
vested shall become fully exercisable and vested, subject only to the restrictions on disposition of equity securities set forth in Section 8.01(ii) and legal restrictions on the issuance of Shares set forth in Sections 8.03 and 8.04; 

(iii) In its sole discretion, and on such terms and conditions as it deems appropriate, the Committee may provide, either by the terms of the
Award Agreement or by resolution adopted prior to the occurrence of such Change of Control, that the restrictions, deferral limitations, and forfeiture conditions applicable to any other Award granted under the Plan shall lapse and such Awards shall
be deemed fully vested, in each case, to the extent provided by the Committee, subject only to the restrictions on dispositions of equity securities set forth in Section 8.01(ii) and legal restrictions on the issuance of Shares set forth in
Sections 8.03 and 8.04; provided, however, that if (i) any such Awards are not Assumed or Replaced, or in the event of a liquidation of the Corporation, or (ii) a Participant’s employment is terminated either by the
Corporation or a Subsidiary without Cause or by the Participant for Good Reason, within twenty-four (24) months after the Change of Control, then the restrictions, deferral limitations, and forfeiture conditions applicable to any other Award
granted under the Plan that (x) is not so assumed or Replaced, or is outstanding at the time of such a liquidation of the Corporation, or (y) is held by a Participant whose employment is so terminated shall lapse and such Awards shall be
deemed fully vested, subject only to the restrictions on dispositions of equity securities set forth in Section 8.01(ii) and legal restrictions on the issuance of Shares set forth in Sections 8.03 and 8.04; 

(iv) Cash-Out.  In the sole discretion of the Committee, all outstanding Awards may be cancelled and in such event a
Participant holding any such Award shall be paid in cash therefor, on or as soon as practicable following the closing date or expiration date of the transaction resulting in the Change of Control, in an amount equal the “Change of Control
Price” (as defined in as of the date that the Change of Control occurs, or such other date as the Committee may determine prior to the Change of Control, over the exercise price of any Option (or of any other Award in the nature of a right that
may be exercised) or base price of any Stock Appreciation Right, as applicable, of the Shares subject to any such cashed-out Option or Stock Appreciation Right multiplied by the number of Shares subject to such an Award; provided,
however, that this Section 9.01(iv) shall not apply in the case of any Award if (a) the cancellation of and payment for such Award would cause the Participant to incur actual short-swing profits liability under Section 16(b) of
the Exchange Act or (b) initial shareholder approval of the Plan has not been obtained; and 
 (v) To the extent Section 9.01(iv)
of this Section 9 does not apply and at any time after the Change of Control the Shares are no longer readily tradable on an established exchange, a Participant shall, as of the date on which the Change of Control occurs, be entitled to receive
consistent with Rule 16b-3, and the Corporation shall use its best efforts to compel and obligate the surviving or resulting corporation in the Change of Control and/or the other party 

  
 18 

 
to the agreement or transaction resulting in the Change of Control to grant to the Participant, substitute Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units and/or
other Awards, as the case may be, in respect of the shares of common stock or other capital stock of such surviving or resulting corporation, or such other party involved in the Change of Control, on such terms and conditions, as to the number of
shares, pricing, vesting, exercisability and otherwise, which shall substantially preserve the value, rights and benefits of any affected Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units and/or other Awards, as the case
may be, previously granted hereunder, as determined by the Committee. 
 9.02 Change of Control.  For purposes of this
Section 9, a “Change of Control” shall mean: 
 (a) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either the then (i) outstanding shares of Common Stock of the
Corporation (the “Outstanding Corporation Common Stock”) or (ii) combined voting power of the then outstanding voting securities of the Corporation entitled to vote generally in the election of directors (the “Outstanding Voting
Securities”) provided, however, that the following acquisitions shall not constitute a Change of Control: (I) any acquisition by the Corporation or any of its subsidiaries, (II) any acquisition by any employee benefit
plan (or related trust) sponsored or maintained by the Corporation or any of its subsidiaries, (III) any acquisition by any corporation with respect to which, following such acquisition, more than 51% of, respectively, the then outstanding
shares of common stock of such corporation and the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally in the election of directors is then beneficially owned, directly or indirectly, by all
or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Corporation Common Stock and Outstanding Voting Securities immediately prior to such acquisition in substantially the same
proportions as their ownership, immediately prior to such acquisition, of the Outstanding Corporation Common Stock and Outstanding Voting Securities, as the case may be, or (IV) any acquisition by one or more Hess Entity (for this purpose a
“Hess Entity” means (A) any of the children of Mr. Leon Hess, (B) any spouse of any person described in Section 9.02(a)(IV)(A) above, (C) any affiliate (as such term is defined in Rule 12b-2 under the Exchange
Act) of any person described in Section 9.02(a)(IV)(A) above, (D) the Hess Foundation Inc., or (E) any persons comprising a group controlled (as such term is defined in such Rule 12b-2) by one or more of the foregoing persons or
entities described in this Section 9.02(a)(IV)); or 
 (b) Individuals who, as of the effective date of the Plan, constitute
the Board (the “Incumbent Board”) ceasing for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the effective date of the Plan whose election,
or nomination for election by the Corporation’s shareholders, 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 office occurs as a 

  
 19 

 
result of either an actual or threatened solicitation to which Rule 14a-l 1 of Regulation 14A promulgated under the Exchange Act applies or other actual threatened solicitation of
proxies or consents; or 
 (c) Consummation (or, for Awards granted prior to February 1, 2010, approval by the shareholders of
the Corporation) of a reorganization, merger or consolidation, in each case, with respect to which all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Corporation Common Stock and
Outstanding Voting Securities immediately prior to such reorganization, merger or consolidation do not, following such reorganization, merger or consolidation, beneficially own, directly or indirectly, more than 51% 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, as the case may be, of the corporation resulting from such reorganization, merger or
consolidation in substantially the same proportions as their ownership, immediately prior to such reorganization, merger or consolidation, of the Outstanding Corporation Common Stock and Outstanding Voting Securities, as the case may be; or 

(d) Consummation (or, for Awards granted prior to February 1, 2010, approval by the shareholders of the Corporation) of (i) a
complete liquidation or dissolution of the Corporation or (ii) the sale or other disposition of all or substantially all of the assets of the Corporation, other than to a corporation, with respect to which following such sale or other
disposition, more than 51% of, respectively, the then outstanding shares of common stock of such corporation and the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally in the election of
directors is then beneficially owned, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Corporation Common Stock and Outstanding Voting Securities
immediately prior to such sale or other disposition in substantially the same proportion as their ownership, immediately prior to such sale or other disposition, of the Outstanding Corporation Common Stock and Outstanding Voting Securities, as the
case may be. The term “the sale or other disposition of all or substantially all of the assets of the Corporation” shall mean a sale or other disposition transaction or series of related transactions involving assets of the Corporation or
of any direct or indirect subsidiary of the Corporation (including the stock of any direct or indirect subsidiary of the Corporation) in which the value of the assets or stock being sold or otherwise disposed of (as measured by the purchase price
being paid therefor or by such other method as the Board determines is appropriate in a case where there is no readily ascertainable purchase price) constitutes more than two-thirds of the fair market value of the Corporation (as hereinafter
defined). The “fair market value of the Corporation” shall be the aggregate market value of the then Outstanding Corporation Common Stock (on a fully diluted basis) plus the aggregate market value of the Corporation’s other
outstanding equity securities. The aggregate market value of the shares of Outstanding Corporation Common Stock shall be determined by multiplying the number of shares of such Common Stock (on a fully diluted basis) outstanding on the date of the
execution and delivery of a definitive agreement with respect to the transaction or series of related transactions (the “Transaction Date”) by the average closing price of the shares of 

  
 20 

 
Outstanding Corporation Common Stock for the ten trading days immediately preceding the Transaction Date. The aggregate market value of any other equity securities of the Corporation shall be
determined in a manner similar to that prescribed in the immediately preceding sentence for determining the aggregate market value of the shares of Outstanding Corporation Common Stock or by such other method as the Board shall determine is
appropriate. 
 Notwithstanding the foregoing, no event or condition shall constitute a Change of Control with respect to an Award to the
extent that, if it were, a 20% tax would be imposed under Section 409A of the Code on the Participant who holds such Award; provided that, in such a case, the event or condition shall continue to constitute a Change of Control to the
maximum extent possible (e.g., if applicable, in respect of vesting without an acceleration of distribution) without causing the imposition of such 20% tax. 

9.03 Change of Control Price.  For purposes of this Section 9, “Change of Control Price” means the highest
price per share paid in any transaction reported on the securities exchange or trading system on which the Shares are then primarily listed or traded, or paid or offered in any transaction related to a Change of Control at any time during the 60-day
period preceding the date of the Change of Control as determined by the Committee, except that “Change of Control Price” with respect to Stock Options and Stock Appreciation Rights means the Fair Market Value of a Share for the date on
which such an Award is cashed out. 
 SECTION 10.    Adjustment Provisions. In the event that any
dividend or other distribution (whether in the form of cash, Shares or other stock, or other property, but excluding regular cash dividends), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, spin-off,
combination, repurchase, or share exchange, or other similar corporate transaction or event, affects the Shares such that an adjustment is necessary in order to prevent dilution or enlargement of the rights of Participants under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and kind of Shares which may thereafter be issued in connection with Awards, (ii) the number and kind of Shares issued or issuable in respect of
outstanding Awards, (iii) the exercise price, base price, or purchase price relating to any Award or, if deemed appropriate, make provision for a cash payment with respect to any outstanding Award and (iv) the maximum Share amounts set
forth in Section 7.02; provided, however, in each case, that, with respect to Incentive Stock Options, no such adjustment shall be authorized to the extent that such authority would cause the Plan to violate Section 422(b)(l)
of the Code. In addition, the Committee is authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, events described in the
preceding sentence) affecting the Corporation or any Subsidiary or the financial statements of the Corporation or any Subsidiary, or in response to changes in applicable laws, regulations, rules or accounting principles. Any adjustments pursuant to
this Section 10 shall be determined by the Committee after taking into account, among other things, the provisions of Section 409A of the Code. 

  
 21 

 SECTION 11.    Changes to the Plan and Awards. 

11.01 Changes to the Plan.  The Board may, at any time and with or without prior notice, amend, alter, suspend,
discontinue or terminate the Plan, retroactively or prospectively, without the consent of shareholders or Participants; provided, however, that, except as is provided in Section 10, any such amendment, alteration, suspension,
discontinuation, or termination shall be subject to the approval of the Corporation’s shareholders within one year after such Board action (i) if such amendment or alteration (v) increases the number of shares reserved for Awards
under the Plan, (w) changes the class of Participants eligible to receive Awards under the Plan, (x) decreases the minimum exercise price or base price requirements of Section 6.06(i) or 6.07(i), (y) modifies or eliminates the
provisions of Section 7.03, 7.04 or 11.03(B), or (z) materially increases the benefits to Participants under the Plan; (ii) if the Board determines that such shareholder approval is required by any federal or state law or regulation
or the rules of any stock exchange on which the Shares may be listed in order to maintain compliance therewith, or (iii) if the Board in its discretion determines that obtaining such shareholder approval is for any reason advisable;
provided, however, that, without the consent of an affected Participant, no amendment, alteration, suspension, discontinuation, or termination of the Plan after initial shareholder approval of the Plan may materially impair the
previously accrued rights of such Participant under any Award theretofore granted to him. 
 11.02 Changes to
Awards.  The Committee may, unless otherwise expressly prohibited by the Plan, at any time and with or without prior notice, waive any conditions or rights under, or amend, alter, suspend, discontinue, or terminate, retroactively or
prospectively, any Award theretofore granted and any Award Agreement relating thereto; provided, however, that, without the consent of an affected Participant, no such amendment, alteration, suspension, discontinuation, or termination
of any Award after initial shareholder approval of the Plan may materially impair the previously accrued rights of such Participant under such Award. 

11.03 Limitations on Changes.  Notwithstanding the foregoing provisions of this Section 11 to the contrary,
(A) the Board may amend or alter the Plan, and the Committee may amend or alter any Award, including any Award Agreement, either retroactively or prospectively, without the consent of the applicable Participant, (a) so as to preserve or
come within any exemptions from liability under Section 16(b) of the Exchange Act, or (b) if the Board or the Committee determines in its discretion that such amendment or alteration either (i) is required or advisable for the
Corporation, the Plan or the Award to satisfy, comply with or meet the requirements of any law, regulation, rule or accounting standard or (ii) is not reasonably likely to significantly diminish the benefits provided under such Award, or that
such diminishment has been or will be adequately compensated, and (B) except in connection with a corporate transaction involving the Corporation (including, without limitation, any stock dividend, stock split, extraordinary cash dividend,
recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares) or as is provided in Section 10, but notwithstanding any other provisions of the Plan, neither the Board nor the Committee may take
any action: (1) to amend the terms of an outstanding Option or Stock Appreciation Right to reduce the exercise price or base price thereof, cancel an Option or Stock Appreciation Right and replace it with a new Option or Stock Appreciation
Right with a lower exercise price or base price, or that has an economic effect that is the same as any such 

  
 22 

 
reduction or cancellation; or (2) to cancel an outstanding Option or Stock Appreciation Right in exchange for cash or the grant of another type of Award or Options or SARs with an exercise
price or grant price that is less than the exercise price of the original Options or SARs, without, in each such case, first obtaining approval of the stockholders of the Corporation of such action. 

SECTION 12.    General Provisions. 

12.01 No Rights to Awards.  No Participant, director, employee or consultant shall have any claim to be granted any Award
under the Plan, and there is no obligation for uniformity of treatment of Participants and directors, employees or consultants. 

12.02 No Shareholder Rights.  No Award shall confer on any Participant any of the rights of a shareholder of the
Corporation unless and until Shares are duly issued or transferred to the Participant in accordance with the terms of the Award. 

12.03 Tax Withholding and Other Tax Matters. 

(i) To the extent and in the manner permitted by applicable law, the Corporation or any Subsidiary is authorized to withhold from any
Award granted, any payment relating to an Award under the Plan, including from a distribution of Shares (provided, however, that the amount of any Shares so withheld shall not exceed the amount necessary to satisfy required Federal,
state, local and non-United States withholding obligations using the minimum statutory withholding rates for Federal, state, local and/or non-U.S. tax purposes, including payroll taxes, that are applicable to supplemental taxable income, except
to the extent the Committee determines to permit additional withholding and determines that doing so would not result in any adverse accounting consequences for the Corporation or a Subsidiary), or any payroll or other payment to a Participant,
amounts or withholding and other taxes due with respect thereto, its exercise, or any payment thereunder, and to take such other action as the Committee may deem necessary or advisable to enable the Corporation or any Subsidiary and Participants to
satisfy obligations for the payment of withholding taxes and other tax liabilities relating to any Award. This authority shall include authority to withhold or receive Shares or other property and to make cash payments in respect thereof in
satisfaction of the Participant’s tax obligations. 
 (ii) If a Participant makes an election under Section 83(b) of the Code
to be taxed with respect to an Award as of the date of transfer of Shares rather than as of the date or dates upon which the Participant would otherwise be taxable under Section 83(a) of the Code, such Participant shall deliver a copy of such
election to the Corporation immediately after filing such election with the Internal Revenue Service. Neither the Corporation nor any Subsidiary shall have any liability or responsibility relating to or arising out of the filing or not filing of any
such election or any defects in its construction. 
 (iii) Although the Corporation intends to administer the Plan so that Awards will
be exempt from, or will comply with, the requirements of Code Section 409A, the Corporation does not warrant that any Award under the Plan will qualify for favorable tax treatment under Code Section 409A or any other provision of federal,
state, local, or non-United States law. 

  
 23 

 12.04 No Right to Employment or Other Service.  Nothing contained in the
Plan or any Award Agreement shall confer, and no grant of an Award shall be construed as conferring, upon any director, employee or consultant any right to continue in the employment or other service of the Corporation or any Subsidiary or to
interfere in any way with the right of the Corporation or any Subsidiary to terminate such employment or other service at any time or increase or decrease such director’s, employee’s or consultant’s compensation from the rate in
existence at the time of granting of an Award. 
 12.05 Unfunded Status of Awards.  The Plan is intended to constitute
an unfunded plan for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended. With respect to any payments not yet made to a Participant pursuant to an Award the Plan constitutes a mere
promise to make the benefit payments provided for herein, and nothing contained in the Plan or any Award shall give any such Participant any rights that are greater than those of a general creditor of the Corporation. The Committee may authorize the
creation of trusts or make other arrangements to meet the Corporation’s obligations under the Plan to deliver cash, Shares, other Awards, or other property pursuant to any award, which trusts or other arrangements shall be consistent with the
unfunded status of the Plan. 
 12.06 Other Compensatory Arrangements.  The Corporation or any Subsidiary shall be
permitted to adopt other or additional compensation arrangements (which may include arrangements which relate to Awards), and such arrangements may be either generally applicable or applicable only in specific cases. 

12.07 Uncertificated Shares.  To the extent that the Plan provides for issuance of certificates to reflect the transfer
of Shares, the transfer of such Shares may nevertheless be effected on a noncertificated basis, to the extent not prohibited by applicable law or the rules of any stock exchange. 

12.08 Fractional Shares.  No fractional Shares shall be issued or delivered pursuant to the Plan or any Award. The
Committee shall determine whether cash, other Awards, or other property shall be issued or paid in lieu of fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated. 

12.09 Forfeiture Events. 

(i) Notwithstanding any provision of the Plan to the contrary, the Committee shall have the authority to determine (and may so provide in
any Agreement) that a Participant’s (including his or her estate’s, beneficiary’s or transferee’s) rights (including the right to exercise any Option or Stock Appreciation Right), payments and benefits with respect to any Award
shall be subject to reduction, cancellation, forfeiture or recoupment (to the extent permitted by applicable law) in the event of the Participant’s termination of employment or service with the Corporation or a Subsidiary for cause (as
determined by the Committee) or due to voluntary resignation; serious misconduct; violation of the Corporation’s or a Subsidiary’s policies; breach of fiduciary duty; unauthorized disclosure of any trade secret or confidential information
of the Corporation or a Subsidiary; breach of applicable noncompetition, nonsolicitation, confidentiality or other restrictive covenants; or other conduct or activity that is in competition with the business of the Corporation or any Subsidiary, or
otherwise detrimental to the business, reputation or interests of the Corporation 

  
 24 

 
and/or any Subsidiary; or upon the occurrence of certain events specified in the applicable Award Agreement (in any such case, whether or not the Participant is then an employee, director or
consultant). The determination of whether a Participant’s conduct, activities or circumstances are described in the immediately preceding sentence shall be made by the Committee in its good faith discretion, and pending any such determination,
the Committee shall have the authority to suspend the exercise, payment, delivery or settlement of all or any portion of such Participant’s outstanding Awards pending an investigation of the matter. 

(ii) If the Corporation is required to prepare an accounting restatement (x) due to the material noncompliance of the Corporation, as
a result of misconduct, with any financial reporting requirement under the securities laws, if a Participant knowingly or grossly negligently engaged in such misconduct, or knowingly or grossly negligently failed to prevent such misconduct, or if a
Participant is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, the Participant shall reimburse the Corporation the amount of any payment in settlement of an Award earned or accrued
during the twelve- (12-) month period following the first public issuance or filing with the SEC (whichever just occurred) of the financial document embodying such financial reporting requirement, and (y) the Committee may in its discretion
provide that if the amount earned under any Participant’s Award is reduced by such restatement, such Participant shall reimburse the Corporation the amount of any such reduction previously paid in settlement of such Award. 

12.10 Transfer, Leave of Absence.  For purposes of the Plan, a transfer of an employee from the Corporation to a
Subsidiary, or vice versa, or from one Subsidiary to another, and a leave of absence, duly authorized in writing by the Corporation or a Subsidiary, shall not be deemed a termination of such employee’s employment for purposes of the Plan or
with respect to any Award. The Committee shall have the discretion to determine the effects upon any Award and upon an individual’s status as an employee, director or consultant of the Corporation or a Subsidiary for purposes of the Plan in the
case of: (a) any Participant who is employed by an entity that ceases to be a Subsidiary (whether due to a spin-off or otherwise), (b) any transfer of a Participant between locations of employment with the Corporation and/or a Subsidiary
or between the Corporation or a Subsidiary or between Subsidiaries, (c) any leave of absence of a Participant, (d) any change in a Participant’s status from an employee to a consultant or a non-employee director, or vice versa; and
(e) any employee who experiences a termination of employment with the Corporation or a Subsidiary but becomes employed by a partnership, joint venture, corporation or other entity not meeting the requirements of a Subsidiary. Notwithstanding
the foregoing, this Section 12.10 shall not cause a Participant to fail to be considered to have terminated employment for purposes of the Plan, to the extent that the Participant would be considered to have had a “separation from
service” with the Corporation or a Subsidiary for purposes of Section 409A of the Code, and it would be necessary in order to comply with Section 409A of the Code to consider such Participant as having so terminated. 

12.11 Participants Deemed to Accept Plan.  By accepting any benefit under the Plan, each Participant and each person
claiming under or through any such Participant shall be conclusively deemed to have indicated their acceptance and ratification of, and consent to, all of the terms and 

  
 25 

 
conditions of the Plan and any action taken under the Plan by the Board, the Committee or the Corporation, in any case in accordance with the terms and conditions of the Plan. 

12.12 Governing Law.  The validity, construction, and effect of the Plan, any rules and regulations relating to the Plan,
and any Award Agreement shall be determined in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of laws, and applicable federal law. 

12.13 Participants Based Outside of the United States.  Notwithstanding any provision of the Plan to the contrary, in
order to comply with the laws or practices of countries other than the United States in which the Corporation and/or any Subsidiary operates or has employees, directors or consultants, the Committee, in its sole discretion, shall have the power and
authority to: 
 (a) Determine which Subsidiaries shall be covered by the Plan; 

(b) Determine which such employees, directors and/or consultants outside the United States are eligible to participate in the Plan; 

(c) Grant Awards (including substitutes for Awards), and modify the terms and conditions of any Awards, on such terms and conditions as
the Committee determines necessary or appropriate to permit participation in the Plan by individuals otherwise eligible to so participate who are non-United States nationals or employed outside the United States, or otherwise to comply with
applicable non-United States laws or conform to applicable requirements or practices of jurisdictions outside the United States; 

(d) Establish subplans and adopt or modify exercise procedures and other terms and procedures, to the extent such actions may be necessary
or advisable. Any subplans and modifications to Plan terms and procedures established under this Section 12.13 by the Committee shall be attached to the Plan as appendices; and 

(e) Take any action, before or after an Award is made, that the Committee, in its discretion, deems advisable to obtain approval or comply
with any necessary local government regulatory exemptions or approvals. 
 Notwithstanding the above, the Committee may not take any actions
hereunder, and no Awards shall be granted, that would violate any applicable law. 
 SECTION 13.    Effective
Date; Duration of Plan. Following adoption of the Plan by the Board, the Plan shall be effective upon the date on which the Plan is approved by the affirmative vote of the holders of a majority of the Shares present or represented and
entitled to vote (and the affirmative vote of a majority of the Shares voting) at a meeting of the Corporation’s shareholders during 2015, or any adjournment thereof. The Plan shall remain in effect, subject to the right of the Board to amend
or terminate the Plan at any time pursuant to Section 11, until all Shares subject to it shall have been delivered, and any restrictions on such Shares have lapsed, pursuant to the Plan’s provisions. However, in no event may an Award be
granted under the Plan on or after May 7, 2018.

(iii)    Anything in this clause (u) to the contrary notwithstanding, the Company shall not be required to give any notice specified in subparagraph (i) or to otherwise furnish the information contemplated therein or to deliver any Opinion of Counsel contemplated by subparagraph (ii) if the Company shall have caused Securities of Series No. 28 to be deemed to have been paid for purposes of the Indenture, as provided in Section 901 of the Original Indenture, but shall not have effected the satisfaction and discharge of its indebtedness in respect of such Securities pursuant to such Section.

(v)The Securities of Series No. 28 shall be substantially in the form attached hereto as Exhibit A, and shall have such further terms as are set forth in such form.

, or registered assigns, the principal sum of 
Dollars on the Stated Maturity specified above, and to pay interest thereon from the Original Interest Accrual Date specified above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi‐annually in arrears on the Interest Payment Dates specified above in each year, commencing November 15, 2015 and at Maturity, at the Interest Rate per annum specified above, until the principal hereof is paid or duly provided for.  The interest so payable, and paid or duly provided for, on any Interest Payment Date shall, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date specified above (whether or not a Business Day) next preceding such Interest Payment Date.  Notwithstanding the foregoing, interest payable at Maturity shall be paid to the Person to whom principal shall be paid.  Except as otherwise provided in said Indenture, any such interest not so paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 15 days prior to such Special Record Date, or be paid in such other manner as permitted by the Indenture.

EXHIBIT A-1

Payment of the principal of this Security and interest hereon at Maturity shall be made upon presentation of this Security at the Corporate Trust Office of U.S. Bank National Association in New York, New York or at such other office or agency as may be designated for such purpose by the Company from time to time.  Payment of interest on this Security (other than interest at Maturity) shall be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, except that if such Person shall be a securities depositary, such payment may be made by such other means in lieu of check as shall be agreed upon by the Company, the Trustee and such Person.  Payment of the principal of and interest on this Security, as aforesaid, shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts.
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and issuable in one or more series under and equally secured by an Indenture, dated as of October 1, 1993 (such Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Securities, being herein called the “Indenture”), between the Company and U.S. Bank National Association as successor trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Securities thereunder and of the terms and conditions upon which the Securities are, and are to be, authenticated and delivered and secured.  The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture.  This Security is one of the series designated above.
If any Interest Payment Date or the Stated Maturity shall not be a Business Day (as hereinafter defined), payment of the amounts due on this Security on such date may be made on the next succeeding Business Day; and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on such amounts for the period from and after such Interest Payment Date or Stated Maturity, as the case may be, to such Business Day.
This Security shall be redeemable at the option of the Company at any time prior to November 15, 2024, in whole or in part, at a “make whole” redemption price equal to the greater of (i) 100% of the principal amount hereof to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on this Security to be redeemed that would be due if this Security matured on November 15, 2024 (excluding the portion of any such accrued and unpaid interest to but excluding the Redemption Date), discounted to but excluding the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus 15 basis points, plus, in each case, accrued and unpaid interest to but excluding the Redemption Date.  At any time on or after November 15, 2024, the Securities shall be redeemable, in whole or in part, at 100% of the principal amount being redeemed plus accrued and unpaid interest thereon to but excluding the Redemption Date. For purposes hereof, the following defined terms shall have the meaning ascribed to them:
“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of this Security (assuming for this purpose, that this Security matured on November 15, 2024) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of this Security.
“Comparable Treasury Price” means (i) the average of the Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations

EXHIBIT A-2

for such Redemption Date, or (ii) if the Trustee obtains fewer than four Reference Treasury Dealer Quotations for the Redemption Date, the average of all of the Reference Treasury Dealer Quotations for such Redemption Date.
“Independent Investment Banker” means Credit Suisse Securities (USA) LLC, RBC Capital Markets, LLC, TD Securities (USA) LLC, U.S. Bancorp Investments, Inc. or their respective successors or, if such firms or their successors are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after consultation with the Company.
“Primary Treasury Dealer” means any primary U.S. Government securities dealer in the United States.
“Reference Treasury Dealer” means (1) each of Credit Suisse Securities (USA) LLC, RBC Capital Markets, LLC, and TD Securities (USA) LLC (or their respective affiliates which are Primary Treasury Dealers), and a Primary Treasury Dealer selected by U.S. Bancorp Investments, Inc. and any other Primary Treasury Dealer designated by, and not affiliated with Credit Suisse Securities (USA) LLC, RBC Capital Markets, LLC, TD Securities (USA) LLC and U.S. Bancorp Investments, Inc., or their respective successors, provided, however, that if any of the foregoing, or any of their respective designees ceases to be a Primary Treasury Dealer, the Company will appoint another Primary Treasury Dealer as a substitute and (2) any other Primary Treasury Dealer selected by the Company after consultation with an Independent Investment Banker.
“Reference Treasury Dealer Quotations” means, for any Reference Treasury Dealer and any Redemption Date, the average, as determined by an Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent Investment Banker by the Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding the Redemption Date. 
“Treasury Yield” means, for any Redemption Date (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Yield will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.  The Treasury Yield for any Redemption Date shall be calculated on the third Business Day preceding such Redemption Date.
If an Event of Default shall occur and be continuing, the principal of this Security may be declared due and payable in the manner and with the effect provided in the Indenture.
The Indenture permits, with certain exceptions as therein provided, the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under the

EXHIBIT A-3

Indenture, considered as one class; provided, however, that if there shall be Securities of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Indenture permits the Trustee to enter into one or more supplemental indentures for limited purposes without the consent of any Holders of Securities.  The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.  Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in the Indenture and subject to certain limitations therein set forth, this Security or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and, at the election of the Company, the Company’s entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with moneys so deposited, will be sufficient to pay when due the principal of and interest on this Security when due.
As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office of U.S. Bank National Association in New York, New York or such other office or agency as may be designated by the Company from time to time, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series of authorized denominations and of like tenor and aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only as registered Securities, without coupons, and only in denominations of $1,000 and integral multiples in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of the same series, of any authorized denominations, as requested by the Holder surrendering the same, and of like tenor upon surrender of the Security or Securities to be exchanged at the office of U.S. Bank National Association, in New York, New York or such other office or agency as may be designated by the Company from time to time.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is

EXHIBIT A-4

registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
The Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act of 1939, as then in effect or any successor statute shall be applicable and except to the extent that the law of any jurisdiction wherein any portion of the property mortgaged pursuant to the Indenture or any indenture supplemental thereto is located shall mandatorily govern the perfection, priority or enforcement of the lien of the Indenture and all indentures supplemental thereto with respect to such portion of the mortgaged property.
As used herein, “Business Day” means any day, other than a Saturday or Sunday, which is not a day on which banking institutions or trust companies in The City of New York, New York, or other city in which is located any office or agency maintained for the payment of principal or interest on this Security, are authorized or required by law, regulation or executive order to remain closed.  All other terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
As provided in the Indenture, no recourse shall be had for the payment of the principal of or interest on any Securities, or any part thereof, or for any claim based thereon or otherwise in respect thereof, or of the indebtedness represented thereby, or upon any obligation, covenant or agreement under the Indenture, against, and no personal liability whatsoever shall attach to, or be incurred by, any incorporator, shareholder, officer or director, as such, past, present or future of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture and all the Securities are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of the Securities.
Unless the certificate of authentication hereon has been executed by the Trustee or an Authenticating Agent by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.
