LONG TERM INCENTIVE COMPENSATION PLAN 

ARTICLE I 
 PURPOSE 

The Hercules Incorporated Long Term Incentive Compensation Plan, the terms of which are herein set forth (as the same is now in effect or as
hereafter amended from time to time, the “Plan”), is intended to advance the interests of Hercules Incorporated, a Delaware corporation (the “Company”), and its stockholders by providing a means by which the Company and its
participating subsidiaries and affiliates shall be able to motivate selected key employees (including officers and directors who are employees) to direct their efforts to those activities that will contribute materially to the Company’s
success. The Plan is also intended to serve the best interests of the stockholders by linking remunerative benefits paid to employees who have substantial responsibility for the successful operation, administration and management of the Company
and/or its participating subsidiaries and affiliates with the enhancement of stockholder value while such key employees increase their proprietary interest in the Company. Finally, the Plan is intended to enable the Company to attract and retain in
its employ highly qualified persons for the successful conduct of its business. 
 The Plan became effective as of April 1, 1991, and was
amended and restated as of June 30, 1993, April 27, 1995, April 24, 1997, and is hereby further amended and restated as of April 29, 1999. Notwithstanding anything to the contrary, the said amended and restated Plan shall not terminate or adversely

No shares of Common Stock shall be delivered pursuant to the exercise, in whole or in part, of any Option, unless and until (i) payment in full
of the Option Price therefor is received by the Company and (ii) compliance with all applicable requirements and conditions of this Plan, the Award Commitment and such rules and regulations as may be established by the Committee that are
preconditions to delivery, including, but not limited to, the requirements and conditions of Section 14.5. Promptly after exercise of the Option, payment in full of the Option Price and compliance with the conditions described in the preceding
sentence, the Company shall effect the issuance to the Optionee of such number of shares of Common Stock as are subject to the Option exercise. 

SECTION 5.7 STOCKHOLDER RIGHTS 

An Optionee shall have none of the rights or privileges of a stockholder with respect to any shares of Common Stock covered by an Option unless
and until the Optionee has given written notice of exercise of the Option, has paid in full the Option Price for such shares of Common Stock and has otherwise complied with this Plan, the Award Commitment and such rules and regulations as may be
established by the Committee, and the shares are issued to him. No adjustment shall be made for dividends in cash or property or other distributions or rights with respect to any such shares of Common Stock for which the record date is prior to the
date on which the Optionee or a transferee of the Option shall have become the holder of record of any such shares covered by the Option. Notwithstanding anything to the contrary, an Option may include dividend equivalents as described in Section
10.4. 
 SECTION 5.8 INCENTIVE STOCK OPTIONS 

5.8.1 Individual Limitation. No Grantee may be granted an ISO under this Plan (or any other plans of the Company or any Participating
Subsidiary) which would result in Common Stock with an aggregate Fair Market Value (measured as of the Date of Grant) of more than $100,000 first becoming exercisable in any one calendar year, or which would entitle such Grantee to purchase a number
of shares greater than the maximum number permitted by Section 422(d)(1) of the Code as in effect on the Date of Grant. 
 5.8.2 Code
Qualification. Whenever possible, each provision in the Plan and in every Option granted under this Plan which is designated by the Committee as an ISO shall be interpreted in such a manner as to entitle the Option to the tax treatment afforded by
Section 422 of the Code. If any provision of the Plan or any Option designated by the Committee as an ISO shall be held not to comply with requirements necessary to entitle such Option to such tax treatment, then (i) such provision shall be deemed
to have contained from the outset such language as shall be 

  
 10 








 
necessary to entitle such Option to the tax treatment afforded under Section 422 of the Code, and (ii) all other provisions of this Plan and the Award Commitment shall remain in full force and
effect. If any Award Commitment covering an Option designated by the Committee to be an ISO under the Plan shall not explicitly include any terms required to entitle such ISO to the tax treatment afforded by Section 422 of the Code, all such terms
shall be deemed implicit in the designation of such Option and such Option shall be deemed to have been granted subject to all such terms. 

5.8.3 Notice of Disposition. An Optionee shall give prompt notice to the Company of any disposition of shares of Common Stock acquired upon
exercise of an ISO if such disposition occurs within either two (2) years after grant or one year after receipt of such shares by such Optionee. Such Optionee shall also comply with any applicable withholding requirements. 

SECTION 5.9 STOCK APPRECIATION RIGHTS AWARDS 

5.9.1 Grants. The Committee may grant SARs at the same time as Optionees are awarded Options under the Plan. Each SAR shall be in tandem with
and relate to a specific Option under the Plan and shall specify that the number of Option Shares subject to the SAR shall be equal to the number of shares of Common Stock that the Optionee is entitled to receive pursuant to the related Option. 

5.9.2 SAR Exercise. A SAR may be exercised, in whole or in part, within the period specified for the exercise of the Option in the related
Option grant only upon surrender of the related Option (or portion thereof) by the Optionee. Each SAR shall be exercisable at such time or times, on the conditions and to the extent, but only to the extent, that the related Option is exercisable,
provided that no such SAR (except in the case of death or physical or mental incapacity) shall be exercisable prior to the expiration of six (6) months following the Date of Grant and, provided further, that any SAR granted hereunder may provide, at
the election of the Committee, that the SAR may be exercised only at a time when the Optionee to whom the SAR has been granted is subject to the provisions of Section 16(b) of the Act. Each SAR and all rights and obligations thereunder shall
terminate and may no longer be exercised upon the termination or exercise of the related Option. An Optionee may exercise a SAR by giving written notice of exercise to the Company stating the number of shares of Common Stock subject to exercisable
Options with respect to which the SARs are being exercised. The date upon which such written notice is received by the Company shall be the exercise date for the SARs. 

An Option and SAR covering the same share of Common Stock may not be exercised simultaneously. 

5.9.3 Value of SAR Payment. If an Optionee exercises a SAR, he shall receive an amount equal to the product of (i) the amount by which the SAR
Fair Market Value on the exercise date of one share of Common Stock exceeds the Option Price of the related Option, times (ii) the number of shares covered by the Option, or portion thereof, which is surrendered. For purposes of this Article V,
“SAR Fair Market Value” of a SAR or share of Common Stock on any date shall be the average of the daily closing prices of a share of Common Stock for five (5) consecutive business days immediately preceding the day in question as reported
on the Composite Tape for New York Stock Exchange Listed Companies and published in the Eastern Edition of The Wall Street Journal, subject to the provisions of Section 5.9.4. 

5.9.4 Time and Method of Payment 

5.9.4.1 Any payment which may become due from the Company by reason of an Optionee’s exercise of a SAR may be paid to the Optionee all in
cash, all in shares of Common Stock or partly in shares and partly in cash, as determined by the Committee. The Committee shall determine the timing of any payment made. 

5.9.4.2 If paid in cash, the amount thereof shall be the amount of appreciation determined under Subsection 5.9.3. The payments to be made, in
whole or in part, in cash upon the exercise of SARs by any Reporting Person shall be made in accordance with the provisions relating to the exercise of SARs of Rule 16b-3 of the General Rules and Regulations under the Act, as in effect at the time
of such exercise, or any law, rule, regulation or other provision that may hereafter replace such Rule. 

  
 11 








 5.9.4.3 In the event that all or a portion of the payment is made in shares of Common Stock, the
number of shares of Common Stock received shall be determined by dividing the amount of the appreciation determined under Subsection 5.9.3 by the SAR Fair Market Value of a share of Common Stock on the exercise date of the SAR. Cash will be paid in
lieu of any fractional share of Common Stock or, if the Committee should so determine, the number of shares of Common Stock will be rounded downward to the next whole share of Common Stock. All shares shall be valued at their SAR Fair Market Value
as of the date of such exercise; provided, however, that with respect to exercises of SARs by an employee who is subject to the provisions of Section 16(b) of the Act during any period commencing on the third business day following the date of
release for publication of the quarterly or annual summary statements of the Company’s sales and earnings and ending on the twelfth business day following such date (a “window period”), the Committee may prescribe, by rule of general
application, such other measure of fair market value per share as the Committee may, in its discretion, determine, but not in excess of the highest sale price of the Common Stock reported on the Composite Tape for New York Stock Exchange Listed
Companies and published in the Eastern Edition of The Wall Street Journal during such window period. Notwithstanding the foregoing, the fair market value (or SAR Fair Market Value, if applicable) of SARs that relate to an ISO, shall not be in excess
of the maximum amount that would be permissible under Section 422 of the Code without disqualifying such option as an ISO under such Section 422. 

5.9.5 Effect of SAR and Option Exercises. Upon exercise of a SAR, the number of shares of Common Stock subject to exercise under the related
Option shall automatically be reduced by the number of shares of Common Stock represented by the Option or portion thereof surrendered, as provided in Subsection 5.1.1. Shares of Common Stock subject to Options or portions thereof surrendered upon
the exercise of SARs shall not be available for subsequent awards under the Plan. The exercise of any number of Options shall result in an equivalent reduction in the number of shares of Common Stock covered by the related SAR and such shares may
not again be subject to a SAR under this Plan. 
 5.9.6 Nature of SARs. SARs shall be used solely as a device for the measurement and
determination of the amount to be paid to Grantees as provided in the Plan. SARs shall not constitute or be treated as property or as a trust fund of any kind. All amounts at any time attributable to the SARs shall be and remain the sole property of
the Company and all Grantees’ rights hereunder are limited to the rights to receive cash and shares of Common Stock as provided in the Plan. 

SECTION 5.10 PERFORMANCE ACCELERATED STOCK OPTIONS AWARDS 

5.10.1 Grants. From time to time and upon the recommendation of the CEO, the Committee may grant PASOs in such number as it may determine to
such Reporting Persons as the Committee may select. From time to time, the CEO may grant PASOs in such number as he may determine to such Nonreporting Persons as he may select; provided, however, each and all such grants shall be subject to
Subsection 5.1.4 and any maximum aggregate amount of PASOs established by the Committee for grants under the Plan for Nonreporting Persons as a group. The Committee shall determine the number of PASOs to be awarded; provided, however, such number of
PASOs shall automatically be reduced on a share for share basis to the extent that shares are issued pursuant to the exercise of the PASO. Subject to Subsection 5.10.2, each PASO shall specify a normal vesting date (“Normal Vesting Date”)
(which shall be less than the PASO Period). 
 5.10.2 Accelerated Date. The date or event designated by the Grantor (which shall be earlier
than the Normal Vesting Date) at which the vesting of some or all PASOs shall occur if the Grantor determines that the applicable Performance Goals have been met. 

5.10.3 PASO Period. The Committee shall determine the term of each PASO. Subject to earlier termination as provided in Article XII, the term
shall not exceed ten (10) years. 

  
 12 








 5.10.4 Exercisability. Subject to Subsection 5.10.2 and Article XII, or as otherwise determined
by the Committee, each PASO shall be exercisable at any time or times during the PASO Period and in such amount or amounts as the Committee may prescribe and specify in the applicable Award Commitment. 

5.10.5 Corporate or Business Goals. From time to time, the Grantor shall determine Performance Goals to be used for, among other things,
purposes of determining the Accelerated Date. If the Grantor shall determine minimum target and/or maximum performance goals and (i) if the minimum performance goal is not reached, then the Normal Vesting Date of the affected PASOs shall not be
accelerated, and the Grantor may either determine new goals on the PASOs or allow the PASOs to vest at the Normal Vesting Date; (ii) if the minimum performance goal is reached but the target performance goal is not reached, then the Grantor may
accelerate the Normal Vesting Date to an Accelerated Date for part of the affected PASOs (as specified in the applicable Award Commitment), and for the remainder of the PASOs, the Grantor may determine new goals or allow the PASOs to vest at the
Normal Vesting Date; (iii) if the performance goal is reached and the maximum performance goal is not reached, then the Grantor may accelerate the Normal Vesting Date to an Accelerated Date for part of the affected PASOs, and for the remainder of
the PASOs, the Grantor may determine new goals or allow the PASOs to vest at the Normal Vesting Date; and (iv) if the maximum performance goal is reached, then the Normal Vesting Date for all affected PASOs shall be accelerated to the Accelerated
Date. 
 5.10.6 PASOs Treated Like Options. Except as otherwise provided in the Plan, PASOs shall be treated identical to Options; provided,
however, that if there is a conflict between a provision specifically covering PASOs and one generally covering Options, then the specific provision shall control as to PASOs. 

ARTICLE VI 
 PERFORMANCE SHARE
AWARDS 
 SECTION 6.1 GRANTS 

From time to time and upon the recommendation of the CEO, the Committee may grant Performance Share Awards in such number as it may determine
to such Reporting Persons as the Committee may select. From time to time, the CEO may grant in such number as he may determine Performance Share Awards to such Nonreporting Persons as he may select; provided, however, each and all such grants shall
be subject to any maximum aggregate number of Performance Shares established by the Committee for grants under the Plan for Nonreporting Persons as a group. 

SECTION 6.2 PERFORMANCE PERIOD 

At the time of a Performance Share Award grant, the Committee shall establish a Performance Period of not less than one year nor more than five
(5) years, commencing the Date of Grant of the Award. 
 SECTION 6.3 PERFORMANCE GOALS 

At the time of each grant, the Committee shall establish for all Performance Share Awards the Performance Goals for the Company and any
Participating Subsidiary, while the CEO (or his designee or designees) shall establish for each individual Performance Share Award the business unit, corporate staff group and individual Performance Goals (other than his own which will be the same
as the Performance Goals for the Company), if any. All of the designated Performance Goals must be met as a precondition to any distribution or payment being made with respect to the Performance Share Award following the end of the Performance
Period. Except as provided in Article XII, these Performance Goals (although their measurement, including adjustments, if any, as permitted under Subsection 6.8.3, will not occur until after the expiration of the applicable Performance Period) must
be met during the continuance of the Grantee’s employment with the Company or any Participating Subsidiary, prior to the expiration of the applicable Performance Period and prior to the lapse of restrictions and delivery of any shares of Common
Stock and/or the making of any payment with respect to the Performance Share Award. Performance Goals may vary among Grantees and among Awards to a Grantee. Performance Goals shall be based upon such performance criteria


  
 13 








 
or combination of factors as the Grantor may deem appropriate, including, but not limited to, specified levels of earnings per share, return on investment, return on stockholders’ equity and
such other goals related to the Company’s performance as are deemed appropriate by the Committee. 
 SECTION 6.4 PAYOUT SCHEDULE 

In tandem with the establishment of the Performance Goals, the Grantor shall establish a Payout Schedule for that Performance Period for each
Performance Share Award. Each Payout Schedule shall establish for each Performance Period minimum, target, maximum and intermediate performance and distribution levels for determining the shares of Common Stock deliverable and/or cash payable, if
any, upon settlement of the Performance Share Award at the conclusion of the Performance Period. 
 SECTION 6.5 ISSUANCE OF STOCK AND STOCK
CERTIFICATES 
 6.5.1 Issuance. As soon as possible after the Date of Grant of a Performance Share Award, the Company shall cause to be
issued to the Grantee such number of shares of Common Stock as prescribed by the applicable Payout Schedule for attainment of target level of performance, that is, the Target Award. Concurrently, the Company shall cause to be issued a stock
certificate or certificates, registered in the name of the Grantee and dated the Date of Grant, evidencing such shares. Each such issuance (of shares and of a stock certificate or certificates) shall be subject throughout the Performance Period to
the terms, conditions and restrictions (including forfeiture and restrictions against transfer provisions of Section 6.6) contained in this Plan and/or the Award Commitment entered into between the registered owner of such shares and the Company,
except as otherwise provided in this Plan. Although not a precondition to the granting of a Performance Share Award, each such issuance shall be subject to forfeiture to the Company as of the date of issuance if an Award Commitment and a stock power
endorsed by the Grantee in blank with respect to the shares of Common Stock covered by the Performance Share Award under this Article VI are not duly executed by the Grantee and timely returned to the Company. 

6.5.2 Custody and Legends. Each certificate for shares of Common Stock issued in respect of the Performance Share Award awarded under
Subsection 6.5.1 shall be held in custody by the Company for the Grantee’s account until the expiration or termination of the applicable Performance Period (except as provided in Article XII) and the satisfaction of any and all other conditions
of the Award Commitment applicable to Performance Shares covered by the Performance Share Award. Such certificate shall be imprinted with a legend to indicate that the transferability thereof and the shares of stock represented thereby are subject
to the terms, conditions and restrictions (including forfeiture and restrictions against transfer) contained in this Plan and/or an Award Commitment entered into between the registered owner of such shares and the Company, a copy of which Plan and
Award Commitment is on file in the office of the Company’s Corporate Secretary. Such legend shall not be removed from any stock certificate evidencing Performance Shares until the lapse or release of the restrictions as described in Section
6.8. Each certificate also shall be subject to appropriate stop-transfer orders. 
 SECTION 6.6 RESTRICTIONS AND FORFEITURES 

The shares of Common Stock issued to a Grantee pursuant to Section 6.5 shall be subject to the following restrictions until the expiration or
termination of the Performance Period established pursuant to Section 6.2: (i) a Grantee shall not be entitled to delivery of a certificate evidencing the shares of Common Stock covered by the Performance Share Award until the expiration or
termination of the Performance Period; (ii) none of such shares of Common Stock may be sold, transferred, assigned, pledged or otherwise encumbered or disposed of during the Performance Period and until the satisfaction of any and all other
conditions; and (iii) all such Common Stock shall be forfeited and returned to the Company and all rights of the Grantee with respect to such Common Stock (including, but not limited to, those specified in Section 6.7) shall terminate without
further obligation on the part of the Company unless (x) the Grantee has remained a regular full time employee of the Company or any Participating Subsidiary until the expiration or termination of the Performance Period (except as provided in
Article XII) and (y) the satisfaction of any and all other conditions of the Award Commitment applicable to such Common Stock covered by the Performance Share Award is completed. Upon the forfeiture of any shares of Common Stock, ownership of such
forfeited shares shall be transferred to the Company without further acts by the Grantee. 

  
 14 








 SECTION 6.7 STOCKHOLDER RIGHTS 

Following registration in the Grantee’s name, and subject to execution of the documents provided for in Section 6.5, during the
Performance Period the Grantee shall have the entire beneficial interest in, and all rights and privileges of a stockholder as to, such shares of Common Stock awarded to him with respect to the target level performance, including, but not limited
to, the right to vote and receive dividends, subject to the restrictions and forfeiture risks set forth in Section 6.6. Any shares of Common Stock distributed as a dividend or otherwise with respect to any shares issued under a Performance Share
Award as to which the restrictions have not yet lapsed shall be subject to the same restrictions as such shares. 
 SECTION 6.8 DELIVERY OF
SHARES AND CASH PAYMENTS 
 6.8.1 Determination of Performance Results and Award Settlement. As soon as practicable after the Performance
Period expires or otherwise terminates with respect to each Performance Share Award, the Committee shall determine whether and the extent to which any corporate Performance Goals were achieved during the Performance Period; and the Grantor shall
determine whether and the extent to which applicable business unit, corporate staff and individual Performance Goals, if any, were achieved during the Performance Period. Following such determinations, a calculation shall be made of the number of
shares of Common Stock whose restrictions shall lapse and shall be deliverable and the cash payable, if any, upon settlement of the Performance Share Award. The computation shall be made by application of the Payout Schedule to the degree of actual
performance achieved against Performance Goals (determined as provided in the preceding sentence). 
 6.8.2 Delivery of Shares and Payment
of Cash 
 6.8.2.1 In the event the minimum level of performance established by the Payout Schedule is not achieved, the entire Performance
Share Award is forfeited, including, without limitation, the shares of Common Stock held in custody pursuant to Section 6.5. 
 6.8.2.2
Should the minimum level of performance established by the Payout Schedule be achieved, the Grantee shall have earned (subject to adjustments as provided by Subsection 6.8.3) the applicable Minimum Award and in settlement thereof the Section 6.6
restrictions on that number of shares of Common Stock held in custody pursuant to Section 6.5 equal to the share number specified by the Payout Schedule for performance at the minimum level shall lapse and as promptly as administratively feasible
thereafter, the Company shall deliver to the Grantee a stock certificate or certificates for the number of shares of Common Stock earned. Upon such delivery, shares remaining in custody (which are the difference between the applicable Minimum Award
and the applicable Target Award) shall be forfeited and ownership transferred to the Company without further acts by the Grantee. 
 6.8.2.3
In the event the target level of the Payout Schedule is achieved, the Grantee shall have earned (subject to adjustments as provided by Subsection 6.8.3) the applicable Target Award and in settlement thereof the Section 6.6 restrictions on all of the
shares held in custody pursuant to Section 6.5 shall lapse and as soon as administratively feasible thereafter the Company shall deliver to the Grantee a stock certificate or certificates for the number of shares of Common Stock earned. 

6.8.2.4 For performance at a level between the minimum performance level of the Payout Schedule and the target level of the Payout Schedule
the Section 6.6 restrictions on that number of shares of Common Stock held in custody pursuant to Section 6.5 equal to the share number specified by the Payout Schedule for performance at the applicable intermediate level shall lapse and as promptly
as administratively feasible thereafter, the Company shall deliver to the Grantee a stock certificate or certificates for the number of shares of Common Stock earned. Upon such delivery, shares remaining in custody (which are the difference between
the number of shares prescribed for the level of performance achieved and the Target Award) shall be forfeited and ownership transferred to the Company without further acts by the Grantee. 

6.8.2.5 Should the maximum level of performance established by the Payout Schedule be attained or exceeded, the Grantee shall have earned
(subject to adjustments as provided by Subsection 6.8.3) the applicable Maximum Award and in settlement thereof (i) the restrictions on that number of shares of Common Stock held in 

  
 15 








 
custody pursuant to Section 6.5 equal to the share number specified by the Payout Schedule for performance at the target level shall lapse and as promptly as administratively feasible thereafter
the Company shall deliver to the Grantee a stock certificate or certificates for the number of shares of Common Stock earned at the target level, and (ii) the share differential between the number of shares specified by the Payout Schedule for
performance at the target level and the number of shares specified in the Payout Schedule for performance at the maximum level of performance shall be paid in cash, shares of Common Stock or a combination thereof, as determined by the Committee.
Such share differential shall have a value which is the product of the number of shares constituting the share differential times the Performance Share Fair Market Value on the vesting date. 

6.8.2.6 For performance between the target level and the maximum level of performance specified in the Payout Schedule (i) the Section 6.6
restrictions on that number of shares of Common Stock held in custody pursuant to Section 6.5 equal to the share number specified by the Payout Schedule for performance at the target level shall lapse and as promptly as administratively feasible
thereafter, the Company shall deliver to the Grantee a stock certificate or certificates for the number of shares of Common Stock earned at the target level, and (ii) the share differential between the share number specified by the Payout Schedule
for performance at the target level and the share number specified by the Payout Schedule for performance at the applicable intermediate level shall be paid in cash, shares of Common Stock or a combination thereof, as determined by the Committee.
Such share differential shall have a value which is the product of the number of shares constituting the share differential times the Performance Share Fair Market Value on the vesting date. 

6.8.2.7 Cash payments normally will be made as soon as practicable following the end of the Performance Period. All shares delivered to a
Grantee pursuant to this Subsection 6.8.2 shall be without the legend described in Subsection 6.5.2 and shall be free of all restrictions and forfeitures, except as otherwise provided by Article XII or imposed by law. No payment will be required
from the Grantee upon the delivery of any shares of Common Stock, except that the amount necessary to satisfy applicable Federal, state or local tax requirements shall be paid by the Grantee in accordance with the requirements of Section 14.1. 

6.8.3 Revisions for Significant Events. When circumstances occur (including, but not limited to, unusual or nonrecurring events, changes in
tax laws or accounting principles or practices) that cause any Performance Goal, Payout Schedule and/or level of performance or distribution specified in a Payout Schedule to be inappropriate in the judgment of the party initially responsible for
establishing the Performance Goal, Payout Schedule and/or performance or distribution level, such party may make such changes as said party deems equitable in recognition of any unforeseen events or changes in circumstances or changed business or
economic conditions. 
 6.8.4 Conditions Precedent. Incentives shall be paid to the Grantee only upon compliance by the Grantee with all
obligations of such Grantee under the Plan and/or the Award Commitment with respect to such Performance Share Awards, including the requirement that, except as provided in Article XII, the Performance Goals (although their measurement, including
adjustments, if any, required by the Committee or the CEO, as provided herein, will not occur until after the expiration of the applicable Performance Period) must be met during the continuance of the Grantee’s employment with the Company or
any of the Participating Subsidiaries, prior to the expiration of the applicable Performance Period and prior to the lapse of restrictions and delivery of any shares of Common Stock and/or the making of any payment with respect to the Performance
Share Award. 
 6.8.5 Performance Share Fair Market Value. As used in this Article VI, “Performance Share Fair Market Value” of a
Performance Share Unit or a share of Common Stock on any date shall be the average of the daily closing prices for a share of Common Stock for the five (5) consecutive trading days immediately preceding the day in question as reported on the
Composite Tape for New York Stock Exchange Listed Companies and published in the Eastern Edition of The Wall Street Journal. 

  
 16 








 ARTICLE VII 

RESTRICTED STOCK AWARDS 
 SECTION
7.1 GRANTS 
 From time to time and upon the recommendation of the CEO, the Committee may grant Restricted Stock Awards in such number as it
may determine to such Reporting Persons as the Committee may select. From time to time, the CEO may grant in such number as he may determine Restricted Stock Awards to such Nonreporting Persons as he may select; provided, however, each and all such

SECTION 7.2 RESTRICTED PERIOD 

At the time of a Restricted Stock Award grant, the Committee shall establish (for all Restricted Stock shares which are then being awarded to a
Participant or, if it is the intent that the total of such shares shall be divided into separate parts, for each part of such total) a Restricted Period of not less than one year or more than five (5) years (the “Restriction Range”),
commencing with the Date of Grant of the Award. Different Restricted Periods may be fixed within the Restriction Range for different parts of the shares of Restricted Stock which are being awarded to a Grantee.

and restrictions against transfer provisions of Section 7.3) contained in this Plan and/or the Award Commitment entered into between the registered owner of such shares and the Company, except as otherwise provided in this Plan. Although not a
precondition to the granting of a Performance Share Award, each such issuance shall be subject to forfeiture to the Company as of the Date of Grant if an Award Commitment and a stock power endorsed by the Grantee in blank with respect to the shares
of Restricted Stock covered by the Award under this Article VII are not duly exercised by the Grantee and timely returned to the Company. 

  
 17

such shares and the Company, a copy of which Plan and Award Commitment is on file in the office of the Company’s Corporate Secretary. Such legend shall not be removed from any stock certificate evidencing such Restricted Stock shares until the
lapse or release of the restrictions as described in Section 7.3. Each certificate also shall be subject to appropriate stop-transfer orders. 

SECTION 7.5 STOCKHOLDER RIGHTS 

Following registration in the Grantee’s name and subject to execution of the documents provided for in Section 7.4, during the Restricted

have not yet lapsed shall be subject to the same restrictions as such Restricted Stock shares.

Upon the expiration (without a forfeiture) or earlier termination of the Restriction Period and the satisfaction of or release from any other
conditions by the Grantee under the Plan and/or the Award Commitment with respect to such shares of Restricted Stock, or at such earlier time as provided under the provisions of Article XII and/or Article XIII, all of such shares shall be released
from all restrictions and forfeiture provisions under Section 7.3, any similar restrictions and forfeiture provisions under the Award Commitment applicable to such shares and all other restrictions and forfeiture provisions of this Plan or such
Award Commitment. As promptly as administratively feasible thereafter the Company shall deliver or cause to be delivered to such Grantee a stock certificate or certificates for the appropriate number of shares of Common Stock, free of such
restrictions and forfeitures, except as otherwise provided by Article XIV or imposed by law. No payment will be required from the Grantee upon the delivery of any shares of Restricted Stock, except that amount necessary to satisfy applicable
Federal, state or local tax requirements shall be paid by the Grantee in accordance with the requirements of Section 14.1. 
 ARTICLE VIII

 PHANTOM UNIT AWARDS 
 SECTION
8.1 GRANTS 
 From time to time and upon the recommendation of the CEO, the Committee may grant Phantom Unit Awards in such number as it may
determine to such Reporting Persons as the Committee may select. From time to time, the CEO may grant Phantom Unit Awards in such number as he may determine to such Nonreporting Persons as he may select; provided, however, each and all such grants
shall be subject to any maximum aggregate number of Phantom Units established by the Committee for grants under the Plan for Nonreporting Persons as a group. 

Notwithstanding the above paragraph, the Committee may at its discretion grant Phantom Units payable in one share of Hercules Common Stock for
each unit at the time of vesting pursuant to Section 8.2. In these cases, such Phantom Units are referred to as Restricted Stock Units and during the period that such Restricted Stock Units are awarded, shall be subject to all the provisions of

 SECTION 8.2 VESTING OF AWARDS 

The amounts credited with respect to each Phantom Unit shall become vested on the date or dates determined and set forth in the applicable
Award Commitment at the time of grant unless vested sooner as described in Article XII of the Plan. The vesting period shall be determined by the Committee, but in no case shall such period be less than one year or more than five (5) years. Vesting
shall be subject to the terms, conditions and provisions hereinafter with respect to forfeiture and termination of Awards or early vesting or forfeiture of Awards in accordance with the provisions of Article XII. 

SECTION 8.3 VALUE OF PHANTOM UNITS PAYMENTS 

The amount payable with respect to each vested Phantom Unit Award shall be the sum of (i) the dividends and interest credited to such account
and (ii) an amount determined by multiplying the number of Phantom Units posted to such account by the Phantom Unit Fair Market Value on the date of vesting. For the purpose of determining such amount the Company shall establish and maintain a
separate memorandum account for each Grantee granted a Phantom Unit Award pursuant to Section 8.1. As of the Date of Grant of each grant of a Phantom Unit Award the Company shall credit to the account of each Grantee who has been granted a Phantom
Unit Award such number of Phantom Units as is specified in the Award. From the Date of Grant until the date that payments under the Plan commence the account of each Grantee shall be credited quarterly with an amount determined by multiplying the
amount of Phantom Units credited to each account by the per share dividend paid quarterly by the Company on its Common Stock. In addition, each account (representing dividends and credited interest) shall be credited quarterly with an amount
determined by multiplying the account balance at the close of each quarter by an amount representing one-fourth of the average per annum rate of interest established by Morgan Guaranty Trust Company (or by such other major New York commercial bank
as the Committee shall designate) in New York from time to time during such quarter as its prime lending rate. As used in this Article VIII, “Phantom Unit Fair Market Value” of a Phantom Unit or a share of Common Stock on any date shall be
the average of the daily closing prices for a share of Common Stock for the five (5) consecutive trading days immediately preceding the day in question as reported on the Composite Tape for New York Stock Exchange Listed Companies and published in
the Eastern Edition of The Wall Street Journal. 
 SECTION 8.4 TIME AND METHOD OF PAYMENT 

Any payment which may become due from the Company upon the vesting of a Phantom Unit shall be paid to the Grantee in cash. The date or dates
upon which amounts determined pursuant to Section 8.3 shall be paid to the Grantee shall be determined by the Committee prior to the Date of Grant and set forth in the applicable Award Commitment or in accord with such rules and regulations as may
be adopted by the Committee. 
 SECTION 8.5 FORFEITURE OF PHANTOM UNITS 

Except as otherwise provided in Article XII, all of the Phantom Units credited to a Grantee’s account (including all dividend equivalents
and interest credited thereto) shall be forfeited and all rights of the Grantee with respect to such Phantom Units (including any dividend equivalents and interest related thereto) shall terminate without further obligation on the part of the
Company unless and until (i) the Grantee has remained a regular full time employee of the Company or any Participating Subsidiary until vesting as described in Section 8.2 and (ii) the satisfaction of any other conditions specified in the Plan
and/or Award Commitment applicable to such Phantom Units, except as may otherwise be determined by the Committee. 
 SECTION 8.6 NATURE OF
PHANTOM UNITS 
 Phantom Units shall be used solely as a device for the measurement and determination of the amount to be paid to Grantees as
provided in the Plan. Phantom Units shall not constitute or be treated as property or as a trust fund of any kind. All amounts at any time attributable to the Phantom Units shall be and remain the sole property of the Company and all Grantees’
rights hereunder are limited to the rights to receive cash and shares of Common Stock as provided in the Plan.

 ARTICLE IX 

CASH VALUE AWARDS 
 SECTION 9.1
GRANTS 
 From time to time and upon the recommendation of the CEO, the Committee may grant Cash Value Awards in such number as it may
determine to such Reporting Persons as the Committee may select. From time to time, the CEO may grant Cash Value Awards in such number as he may determine to such Nonreporting Persons as he may select; provided, however, each and all such grants
shall be subject to any maximum dollar value established by the Committee for grants under the Plan for Nonreporting Persons as a group. 

SECTION 9.2 PERFORMANCE PERIOD 

At the time of a Cash Value Award grant, the Committee shall establish a Performance Period of not less than one year nor more than five (5)
years, commencing on the Date of Grant of the Award. 
 SECTION 9.3 PERFORMANCE GOALS 

At the time of each grant, the Committee shall establish for all Cash Value Awards the Performance Goals for the Company and any Participating
Subsidiary, while the CEO (or his designee or designees) shall establish for each individual Cash Value Award the business unit, corporate staff group and individual Performance Goals (other than his own which will be the same as the Performance
Goals for the Company), if any. All of the designated Performance Goals must be met as a precondition to any distribution or payment being made with respect to the Cash Value Award following the end of the Performance Period. Except as provided in
Article XII, these Performance Goals (although their measurement, including adjustments, if any, will not occur until after the expiration of the applicable Performance Period) must be met during the continuance of the Grantee’s employment with
the Company or any Participating Subsidiary, prior to the expiration of the applicable Performance Period and prior to the making of any payment with respect to the Cash Value Award. Performance Goals may vary among Grantees and among Awards to a
Grantee. Performance Goals shall be based upon such performance criteria or combination of factors as the Grantor may deem appropriate, including, but not limited to, specified levels of earnings per share, return on investment, return on
stockholders’ equity and such other goals related to the Company’s performance as are deemed appropriate by the Committee. 

SECTION 9.4 PAYOUT SCHEDULE 
 In
tandem with the establishment of the Performance Goals, the Grantor shall establish a Payout Schedule for that Performance Period for each Cash Value Award. Each Payout Schedule shall establish for each Performance Period minimum, target, maximum
and intermediate performance and distribution levels for determining the payout of the Common Stock, if any, of the Cash Value Award at the conclusion of the Performance Period. 

SECTION 9.5 FORM OF PAYOUT 

Payment of a Cash Value Award shall be made in cash, Common Stock, Restricted Stock or any combination thereof as determined by the Grantor at
the time of the Payout. Restricted Stock shall be governed by Articles VII and XII; provided, however, that Restricted Stock granted at less than Fair Market Value shall also be governed by Section 9.6 and the Attributable Shares (defined below)
shall be governed by Section 13.3. 
 SECTION 9.6 CALCULATION OF PAYOUT 

As soon as practicable after the Performance Period expires with respect to the Cash Value Award, the Grantor shall determine whether and the
extent to which any Performance Goals were achieved during the Performance Period. The Grantor may also determine the amount and form of the Payout. If the Payout is to be paid in Restricted Stock, then the number of shares calculated by the Grantor
may be determined by using either 100% or 85% (as determined by the Committee) of the Fair Market Value on the date of issue. If the Grantor uses 85% of the Fair Market Value, then those shares attributable to the discount (i.e., 100% minus 85%)
(the “Attributable Shares”) shall be subject to the forfeiture provisions under Section 13.3; and otherwise, the Restricted Stock shall be subject to forfeiture under Article XII.

MARKET-BASED AWARDS

such Other Performance-Based Awards shall be made. Any such Other Performance-Based Award shall be confirmed by an Award Commitment executed by the Company and the Grantee, which Agreement shall contain such provisions as the Committee determines to
be necessary or appropriate to carry out the intent of the Plan with respect to such Award. 
 SECTION 10.3 TERMS OF OTHER AWARDS 

In addition to the terms and conditions specified in the Award Commitment, awards made pursuant to this Article X shall be subject to the
following: 
 (a) Any shares of Common Stock subject to Awards made under this Article X may not be sold, assigned,

(c) The Award Commitment with respect to any Award shall contain provisions dealing with the disposition of such Award in the
event of a termination of employment prior to the exercise, realization or payment of such Award, whether such termination occurs because of retirement, disability, death or other reason, with such provisions to take account of the specific nature
and purpose of the Award. 
 SECTION 10.4 STOCK OPTION DIVIDEND EQUIVALENTS. 

10.4.1 Grants. The Grantor may provide that a Grantee to whom an Option has been granted which is exercisable in whole or in part at a future

Shares, as of the dividend record dates occurring during the period between the Date of Grant and the time each such Share is delivered pursuant to exercise of such Stock Option or the related Stock Appreciation Right. Such amounts (herein called
“Dividend Equivalents”) shall be paid in cash at the time of the delivery of such Shares. 

  
 21 








 10.4.2 Interest. The Grantor may authorize payment of interest on Dividend Equivalents. The
interest will be payable in cash at the same time the related Dividend Equivalents are paid. 
 10.4.3 Forfeiture. To the extent the Stock
Options to which Dividend Equivalents and interest are related shall be forfeited all accrued Dividend Equivalents and interest thereon shall also be forfeited.

Salary and/or earned Bonus and, thereafter, exchange such deferred amounts for Restricted Stock. Such elections shall direct deferrals and exchanges on a one-time (annual) basis or, in the alternative in the case of Base Salary, on an ongoing basis
covering a period not exceeding five (5) years. Should a Grantee elect a one-time (annual) exchange, the deferred amounts shall be credited to his or her deferred compensation account under this Plan and, thereafter, on the third (3rd) business day
following the public announcement of the Company’s annual earnings, the deferred amounts shall be exchanged for that number of shares of Restricted Stock that equals the number of whole shares determined by dividing the deferred amount forgone
by 85% of the Fair Market Value of one share of Common Stock on the date of the exchange. Should a Grantee elect an exchange of Base Salary on an ongoing basis for a period of one year or less, the number of shares of Restricted Stock he or she
shall acquire through such exchanges, which shall be effected on the third (3rd) business day following the public announcement of the Company’s annual earnings, shall be determined by dividing the total projected deferred amounts forgone for
the designated period by 85% of the Fair Market Value of one share of Common Stock on the date of the exchange. When the elected period extends beyond one year, the number of shares of Restricted Stock acquired through such exchanges, which shall be
effected on the third (3rd) business day following the public announcement of the Company’s annual earnings, shall equal that number of whole shares of Restricted Stock determined by dividing the discounted present value of the total projected
deferred amounts forgone for the designated period (using the appropriate Treasury Bill rates for the applicable period) by 85% of the Fair Market Value of one share of Common Stock on the date of the exchange. Restricted Stock acquired pursuant to
exchanges under this Subsection 13.1.1 shall have a Restricted Period of not less than three (3) years (such Restricted Period to be extended up to five (5) years to coincide with a deferral election that extends beyond three (3) years), as
determined by the Committee, and shall be subject to all of the terms, conditions and provisions of Article VII, except as may otherwise be determined by the Committee prior to their acquisition. 

13.1.2 Options. A Grantee may elect to reduce and defer his or her current or future Base Salary and/or earned Bonus and, thereafter, exchange
such deferred amounts for Nonqualified Options. Such elections shall direct deferrals and exchanges on a one-time (annual) basis or, in the alternative in the case of Base Salary, on an ongoing basis covering a period not exceeding five (5) years.
Should a Grantee elect a one-time (annual) exchange, the deferred amounts shall be credited to his or her deferred compensation account under this Plan and, thereafter, on the third (3rd) business day following the public announcement of the
Company’s annual earnings, the deferred amounts shall be exchanged for that number of Options as is determined by the Committee, in its discretion, to be the equivalent in value of that number of whole shares of Restricted Stock determined by
dividing the deferred amount forgone by 85% of the Fair Market Value of one share of the Common Stock on the date of the exchange. Should a Grantee elect an exchange of Base Salary on an ongoing basis for a period of one year or less, the number of
Options he or she shall acquire through such exchanges is that number of Options as is determined by the Committee, in its discretion, to be the equivalent in value of that number of whole shares of Restricted Stock determined by dividing the total
projected deferred amount forgone for the designated period by 85% of the Fair Market Value of one share of Common Stock on the date of the exchange. When the elected period extends beyond one year, the Options acquired through such exchanges, which
shall be effected on the third (3rd) business day following the public announcement of the Company’s annual earnings, shall be that number of Options determined by the Committee, in its discretion, to be the equivalent in value of that number
of whole shares of Restricted Stock determined by dividing the discounted present value of the total projected deferred amounts forgone for the designated period (using the appropriate Treasury Bill rates for the applicable period) by 85% of the
Fair Market Value of one share of the Common Stock on the date of the exchange. Options acquired pursuant to this Subsection 13.1.2 shall be exercisable according to the following three (3)-year schedule (unless the Grantee’s employment with
the Company or a Participating Subsidiary is terminated, in which case the provisions of Section 13.3 or Article XII, as apposite, shall govern): 

40% of the Options will be exercisable beginning one year after the exchange, a second 40% of the Options will be exercisable beginning two (2)
years after the exchange, and the final 20% of the Options will be exercisable beginning three (3) years after the exchange; 

  
 27 








 and shall be subject to all of the terms, conditions and provisions of Article V (as modified as to
exercisability by this Subsection 13.1.2), except as may otherwise be determined by the Committee prior to their acquisition. 
 SECTION
13.2 DEFERRED ACCOUNTS 
 13.2.1 Deferred Compensation Plan Accounts. Subject to the Company’s approval, amounts accrued under the
Hercules Incorporated Deferred Compensation Plan (other than under the Hercules Incorporated Non-qualified Savings Plan portion thereof) may, upon the Grantee’s request for a one-time (annual) exchange, be surrendered in exchange for Restricted
Stock and/or Nonqualified Options. The number of shares of Restricted Stock and Options acquired in this manner shall be determined in the same manner as is specified in Subsections 13.1.1 and 13.1.2, respectively, and all Restricted Stock and
Options so acquired shall be subject to all of the terms, conditions and provisions of Subsections 13.1.1 and 13.1.2, respectively. Exchanges under this Subsection 13.2.1 shall be effected the third (3rd) business day after the first public
announcement of the Company’s annual earnings. 
 13.2.2 Non-Qualified Savings Plan Accounts. Subject to the Company’s approval,
amounts accrued under the Hercules Incorporated Non-Qualified Savings Plan portion of the Hercules Deferred Compensation Plan may, upon the Grantee’s request for a one-time (annual) exchange, be surrendered in exchange for Restricted Stock
and/or Nonqualified Options. The number of shares of Restricted Stock and Options acquired in this manner shall be determined in the same manner as is specified in Subsections 13.1.1 and 13.1.2, respectively, except that the computation in each case
shall be based on 100% of the Fair Market Value of one share of Common Stock rather than the 85% of the Fair Market Value specified in Subsections 13.1.1 and 13.1.2. All Restricted Stock and Options so acquired shall be subject to all of the terms,
conditions and provisions of Subsections 13.1.1 and 13.1.2, respectively. Exchanges under this Subsection 13.2.2 shall be effected the third (3rd) business day after the first public announcement of the Company’s annual earnings. 

SECTION 13.3 TERMINATION OF EMPLOYMENT 

13.3.1 Death, Disability and Reduction in Force. Notwithstanding any provisions of Sections 12.2 and 12.4 to the contrary:

Subsections 13.1.1, 13.2.1 and/or 13.2.2 shall cease to be employed by the Company by reason of Death, Disability, Reduction in Force or Retirement directly attributable to a Reduction in Force, all restrictions and forfeiture provisions under this

(b) If prior to the expiration of an applicable Option Period a Grantee who has received Options pursuant to Subsections
13.1.2, 13.2.1 and/or 13.2.2 shall cease to be employed by the Company by reason of Death, Disability, Reduction in Force or Retirement directly attributable to a Reduction in Force, the Option Period shall be adjusted to the lesser of the remaining
Option Period or one year from the date of employment termination. Notwithstanding the foregoing, the Committee may, in its sole discretion, on a case-by-case basis, determine for new Options, or extend for outstanding Options, the period during
which the Options may be exercised after the Grantee dies or suffers a Disability, provided that such post-termination exercise period may not extend beyond the expiration of the stated Option Period. 

  
 28 








 13.3.2 Retirement. Notwithstanding any provisions of Section 12.1 to the contrary: 

(a) In the event of Retirement (not directly attributable to a Reduction in Force) by a Grantee who has received Restricted
Stock pursuant to Subsections 13.1.1, 13.2.1 and/or 13.2.2 prior to the expiration of an applicable Restricted Period, that number of shares of Restricted Stock equal to the amount attributable to the 15% discount made available under this Article
XIII, and prorated for the length of time remaining in the Restricted Period, shall be forfeited and returned to the Company. 

(b) If prior to the expiration of an applicable Option Period a Grantee who has received Options pursuant to Subsections
13.1.2, 13.2.1 and/or 13.2.2 shall cease to be employed by the Company by reason of his or her Retirement (not directly related to a Reduction in Force), the Option Period shall be adjusted to the lesser of the remaining Option Period or five (5)
years from the date of termination. In the event of Retirement (not directly attributable to a Reduction in Force) by a Grantee who has received Options pursuant to Subsections 13.1.2, 13.2.1 and/or 13.2.2, a number of Options equal to the amount
attributable to the 15% discount and prorated for the length of time remaining in the period during which Options may not be exercised shall be forfeited. 

13.3.3 Resignation or Termination for Cause. Notwithstanding any provisions of Sections 12.5 and 12.7 to the contrary: 

(a) In the event a Grantee who has received Restricted Shares pursuant to Subsections 13.1.1, 13.2.1 and/or 13.2.2 voluntarily
resigns (except for retirement with approval of the Company) or terminates employment for reasons other than any of those specified in Sections 12.1, 12.2, 12.3, 12.4 and 12.6 prior to the expiration of an applicable Restricted Period, all shares of
Restricted Stock shall be forfeited and returned to the Company and such Grantee shall receive a payment equal to the lower of the Fair Market Value of the Restricted Shares forfeited or the original amount exchanged.

forfeited and returned to the Company and such Grantee shall receive a payment equal to the lower of a value (as determined by the Committee) of the Options forfeited or the original amount exchanged. 

SECTION 13.4 AVOIDANCE OF PENSION DIMINUTION 

13.4.1 Governing Provisions. Grantees electing Base Salary and/or Bonus reductions under Section 13.1 may suffer a permanent diminution of
their qualified pension entitlement under the Hercules Pension Plan. To offset this diminution in part, exchange awards in respect of pensions otherwise payable as nonqualified pensions (as measured from the date of the APD Election defined next
below) may be requested within five (5) years of anticipated retirement. Subject to the Committee’s approval of such a request, all such exchanges shall be effected in accordance with the provisions of this Section 13.4. 

13.4.2 Exchange Awards. A Grantee who is within five (5) years (but not less than one year) of his or her anticipated retirement date may
elect (“APD Election”) to exchange the present value (as of the date of the APD Election) of his or her projected benefits payable as of the Designated Retirement Date (as defined below) under the Hercules Pension Restoration Plan
(utilizing the method and assumptions used to convert a pension to a partial cash payment under the Hercules Pension Plan) for Restricted Stock issuable under Subsection 13.1.1 and/or Options granted under Subsection 13.1.2. Restricted Stock and/or
Options received in such an exchange shall be in substitution of any pension entitlements under the Hercules Pension Restoration Plan, the rights to such entitlements being forfeited and canceled in consideration of such exchange. 

  
 29 








 13.4.3 Designated Retirement Date. As a part of his or her APD Election, a Grantee shall
designate a retirement date (“Designated Retirement Date”). In the event of any termination of employment prior to the Designated Retirement Date, the following will apply: 

(a) If the Grantee elected Restricted Stock, that number of Restricted Stock shares shall be forfeited as has a value (on the
date of his or her APD Election) equivalent to the present value determined for purposes of Subsection 13.4.2 minus the present value (as of the APD Election date) of the amount due under the Hercules Pension Restoration Plan as of the date of
actual retirement, utilizing the method and assumptions used to convert a pension to a partial cash payment under the Hercules Pension Plan. Further, in the event that the Grantee’s actual retirement date occurs within three (3) years of the
APD Election, the Grantee shall forfeit that number of Restricted Stock shares (adjusted by the preceding sentence) attributable to the 15% discount made available under Subsection 13.1.1 and prorated for the length of time remaining in the three
(3)-year period commencing with the date of the APD Election. 
 (b) If the Grantee elected Nonqualified Options, that number
of Options shall be forfeited as the Committee in its discretion shall determine has a value (on the date of his or her APD Election) equivalent to the present value determined for purposes of Subsection 13.4.2 minus the present value (as of the
date of his or her APD Election) of the amount due under the Hercules Pension Restoration Plan as of the date of actual retirement, utilizing the method and assumptions used to convert a pension to a partial cash payment under the Hercules Pension
Plan. Further, in the event that the Grantee’s actual retirement date occurs within three (3) years of the APD Election, the Grantee shall forfeit that number of Options as the Committee in its discretion shall determine has a value equal to
that number of Restricted Stock shares (adjusted by the preceding sentence) attributable to the 15% discount made available under Subsection 13.1.2 and prorated for the length of time remaining in the period commencing with the date of the APD
Election. 
 (c) Notwithstanding (a) and (b) next above, in the event of the Grantee’s death, Disability or termination
of employment with the consent of the Company, the Committee may, in its discretion, waive any forfeitures otherwise applicable under this Subsection 13.4.3.

SECTION 13.7 MICP AWARDS

 ARTICLE XIV 

CERTAIN TERMS APPLICABLE TO ALL AWARDS 

SECTION 14.1 WITHHOLDING TAXES 

The Company shall withhold (or secure payment from the Grantee in lieu of withholding) the amount of any withholding or other tax required by
law to be withheld or paid by the Company with respect to any amount payable and/or shares issuable under such Grantee’s Award, or with respect to any income recognized upon a disqualifying disposition of shares received pursuant to the
exercise of an ISO, and the Company may defer payment or issuance of the cash or stock upon exercise or vesting of an Award unless indemnified to its satisfaction against any liability for any such tax. The amount of such withholding or tax payment
shall be determined by the Committee and shall be payable by the Grantee at the time of delivery or when payment is made [except as otherwise payable under Section 14.1(c)] in accordance with the following rules: 

(a) With respect to Awards payable in cash, the Company will withhold an amount sufficient to satisfy applicable Federal, state
and local tax withholding requirements and remit the net award to the Grantee; 
 (b) With respect to Awards payable in
stock, the Company will notify the Grantee of the amount due from such Grantee to satisfy the tax withholding requirements with respect to the stock. The Grantee shall pay the amount due to satisfy the tax withholding requirements in cash; provided,
however, that the Grantee may elect to meet the tax withholding requirement by requesting the Company, in writing, to withhold from such Award and sell through a brokerage firm the appropriate number of shares of Common Stock, rounded up to the next
whole number, which would result in proceeds equal to the tax withholding requirement. Any election by a Grantee to have shares withheld under this Section 14.1 shall be subject to such terms and conditions as the Committee may specify, which may
include that the election shall be irrevocable and in the case of a Reporting Person, the election to have shares withheld under this Section 14.1 must be made either (i) not less than six (6) months prior to the date that the tax is to be withheld
by the Company, or (ii) during the period beginning on the third business day following the date of the release for publication of the Company’s quarterly or annual summary statements of earnings and ending on the twelfth business day following
such date. If the cash required (whether paid directly or indirectly through the sale of stock election described above) is not received by the Company within sixty (60) days of notification by the Company of the tax withholding due, the Committee
shall have the right to take whatever action it deems appropriate, including voiding the Award. The Company shall not deliver or pay the Award (net of the tax withholding) until the tax withholding obligation is satisfied. At the time that all other
restrictions lapse (other than being subject to Section 16 of the Act) a Reporting Person shall make the election described in Subsection (c) below. 

(c) If permitted under applicable Federal income tax laws, a Grantee may elect to include in gross income for Federal income
tax purposes in the year in which a stock Award is made, an amount equal to the Fair Market Value of the Award on the Date of Grant. If the Grantee makes such an election, the Grantee shall promptly notify the Company in writing and shall provide
the Company with a copy of the executed election form as filed with the Internal Revenue Service by no later than thirty (30) days from the Date of the Grant. Promptly following such notification, the Grantee shall pay directly to the Company, or
make arrangements satisfactory to the Committee, the cash amount determined by the Company to be sufficient to satisfy applicable Federal, state or local withholding tax requirements. If the Grantee shall fail to make such payments, the Company and
its Subsidiaries shall, to the extent permissible by law, have the right to deduct from any payment of any kind otherwise due to the Grantee any Federal, state or local taxes of any kind required by law to be withheld with respect to such Restricted
Stock. 
 SECTION 14.2 ADJUSTMENTS TO REFLECT CAPITAL CHANGES 

14.2.1 Recapitalization. In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation or other
change in capitalization with a similar substantive effect upon the Plan or the Awards granted under the Plan, such adjustments shall be made in the number and kind of shares subject to outstanding Awards, the Option Price for such shares and the
number and kind of shares available for Awards subsequently granted under the Plan as may be determined appropriate by the Committee. 

  
 31 








 14.2.2 Sale or Reorganization. After any reorganization, merger or consolidation in which the
Company is the surviving corporation, each Grantee shall, at no additional cost, be entitled upon any exercise of an Option or receipt of other Award to receive (subject to any required action by stockholders), in lieu of the number of shares of
Common Stock receivable or exercisable pursuant to such Award, the number and class of shares of stock or other securities to which such Grantee would have been entitled pursuant to the terms of the reorganization, merger or consolidation if, at the
time of such reorganization, merger or consolidation, such Grantee had been the holder of record of a number of shares of stock equal to the number of shares receivable or exercisable pursuant to such Award. Comparable rights shall accrue to each
Grantee in the event of successive reorganizations, mergers or consolidations of the character described above. 
 14.2.3 Options to
Purchase Stock of Acquired Companies. After any reorganization, merger or consolidation in which the Company or a Subsidiary shall be a surviving corporation, the Committee may grant substituted options under the provisions of the Plan, pursuant to
Section 424 of the Code, replacing old options granted under a plan of another party to the reorganization, merger or consolidation whose stock subject to the old options that may no longer be issued following such merger or consolidation. The
foregoing adjustments and manner of application of the foregoing provisions shall be determined by the Committee in its sole discretion. Any such adjustments may provide for the elimination of any fractional shares which might otherwise become
subject to any Options. 
 SECTION 14.3 FAILURE TO COMPLY WITH TERMS AND CONDITIONS 

Notwithstanding any other provision of the Plan, no payment or delivery with respect to any Award shall be made, and all rights of the Grantee
who receives such Award (or his designated Beneficiary or legal representative) to such payment or delivery under the Plan shall be forfeited, at the discretion of the Committee, if, prior to the time of such payment or delivery, the Grantee
breaches a restriction or any of the terms, restrictions and/or conditions of the Plan and/or the Award Commitment. 
 SECTION 14.4
FORFEITURE UPON OCCURRENCE OF CERTAIN EVENTS 
 Notwithstanding any other provision of the Plan, no payment of any Award shall be made and
all rights of the Grantee who received such Award (or his designated Beneficiary or legal representative) to the payment thereof under the Plan shall be forfeited if, prior to the time of such payment, the Grantee (i) without the Company’s
consent, shall be employed by a competitor of, or shall be engaged in any activity in competition with, the Company or a Subsidiary; (ii) divulges without the consent of the Company any secret or confidential information belonging to the Company or
a Subsidiary; or (iii) has been dishonest or fraudulent in any matter affecting the Company or a Subsidiary or has committed any act which, in the sole judgment of the Committee, has been substantially detrimental to the interests of the Company or
a Subsidiary. The Company shall give a Grantee written notice of the occurrence of any such event prior to making any such forfeiture. The determination of the Committee as to the occurrence of any of the events specified in clauses (i), (ii), and
(iii) of this Section 14.4 shall be conclusive and binding upon all persons for all purposes. Any Award shall be subject to forfeiture for the reasons provided in this Section 14.4 in such manner as shall be provided by the Committee. 

SECTION 14.5 REGULATORY APPROVALS AND LISTING 

The Company shall not be required to issue any certificate or certificates for shares of Common Stock under the Plan prior to (i) obtaining any
approval from any governmental agency which the Company shall, in its discretion, determine to be necessary or advisable, (ii) the admission of such shares to listing on any national securities exchange on which the Company’s Common Stock may
be listed, and (iii) the completion of any registration or other qualification of such shares of Common Stock under any state or Federal law or ruling or regulations of any governmental body which the Company shall, in its discretion, determine to
be necessary or advisable. 

  
 32 








 SECTION 14.6 RESTRICTIONS UPON RESALE OF STOCK 

If the shares of Common Stock that have been issued to a Grantee pursuant to the terms of the Plan are not registered under the Securities Act
of 1933, as amended (“Securities Act”), pursuant to an effective registration statement, such Grantee, if the Committee shall deem it advisable, may be required to represent and agree in writing (i) that any such shares acquired by such
Grantee pursuant to the Plan will not be sold except pursuant to an effective registration statement under the Securities Act, or pursuant to an exemption from registration under said Act and, (ii) that such Grantee is acquiring such shares for his
own account and not with a view to the distribution thereof. 
 SECTION 14.7 REPORTING PERSON LIMITATION 

Notwithstanding any other provision of the Plan, to the extent required to qualify for the exemption provided by Rule 16b-3 under the Act, and
any successor provision, (1) any Common Stock or other equity security offered under the Plan to a Reporting Person may not be sold for at least six (6) months after the earlier of acquisition of the security or the date of grant of the derivative
security, if any, pursuant to which the Common Stock or other equity security was acquired; and (2) any Option, SAR or other similar right related to an equity security, issued under the Plan to a Reporting Person shall not be transferable other
than by will or the laws of descent and distribution, or pursuant to a qualified domestic relations order and shall be exercisable during the Grantee’s lifetime only by the Grantee or the Grantee’s guardian or legal representative. 

ARTICLE XV 
 DISPUTES 

If the employment of a Grantee with the Company or any Participating Subsidiary shall terminate prior to the expiration of the Performance or
Restriction Period applicable to any Performance Share, Restricted Stock, Restricted Stock Unit or Phantom Unit Award awarded to such Grantee and there exists a dispute between such Grantee and the Company or the Committee as to the satisfaction of
the conditions to the release of such shares or units under the Plan or the terms and conditions of the Performance Share, Restricted Stock, Restricted Stock Unit, or Phantom Unit Award, the Performance Share, Restricted Stock, Restricted Stock Unit
or Phantom Unit Awards as to which such dispute shall exist shall remain subject to the restrictions of the Plan until the resolution of such dispute, regardless of any intervening expiration of the Performance or Restriction Period originally
applicable to such shares, except that any dividends which may be declared and which may be payable to the participant as of a date during the period from termination of such Grantee’s employment to the resolution of such dispute (the
“Suspension Period”) shall 
 (i) to the extent to which such dividends would have been payable to such Grantee on
such Performance Share, Restricted Stock, Restricted Stock Unit or Phantom Unit Award, be held by the Company as part of its general funds and shall be paid to or for the account of such Grantee only upon, and in the event of, a resolution of such
dispute in a manner favorable to such Grantee and then only with respect to such Performance Share, Restricted Stock, Restricted Stock Unit or Phantom Unit Award as to which such resolution shall be so favorable, and 

(ii) in the event the dispute is resolved in a manner unfavorable to the Grantee, be canceled as dividends payable upon
Performance Share, Restricted Stock, Restricted Stock Unit or Phantom Unit Award as to which such resolution shall be so unfavorable. 
 In
addition, to the extent that resolution of any such dispute shall be unfavorable to the Grantee, the Performance Shares, Restricted Stock, Restricted Stock Unit or Phantom Unit Award as to which such dispute shall have existed shall be forfeited in
accordance with the provisions of Article XII or Section 14.4.

shall be deemed to have occurred unless and until a “person” (as such term is used in Sections 13(d) and 14(d)(2) of the Act) together with all “affiliates” and “associates” of such person (as such terms respectively,
are defined in Rule 12b-2 of the General Rules and Regulations under the Act) is or becomes a beneficial owner, directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company’s then

Company or by any other person, committee or entity of any kind shall be required to make any modification, alteration or amendment; provided, however, that the Board shall not, without the requisite


  
 35 








 
affirmative approval of the stockholders of the Company, make any modification, alteration or amendment which (i) except as provided in Section 3, increases the maximum number of shares of Common
Stock available for Awards under this Plan, (ii) decreases the Option Price to less than 100% of the Fair Market Value on the Date of Grant of an Option, (iii) extends the period during which Awards may be granted under the Plan beyond April 30,

have been granted under the Plan adversely affect any right of such Grantee under such Award, except in accordance with the provisions of the Plan and/or any Award Commitment applicable to any such Award. Subject to the provisions of this Section
19.1, any modification, alteration or amendment of any provisions of the Plan may be made retroactively. 
 SECTION 19.2 SUSPENSION OR
TERMINATION

Plan for any reason and without the consent of or approval by the stockholders of the Company, any Grantee or Beneficiary or any other person, committee or entity of any kind; provided, however, that no such suspension or termination shall affect
any right or obligation with respect to any Award theretofore made except as herein otherwise provided.

such Option, nor substitute new Options for previously granted Options having a higher Option Price.

 ARTICLE XX 

MISCELLANEOUS 
 SECTION 20.1
DEFERRAL ELECTION 
 At the discretion of the Committee payment of Phantom Units or any other cash award, or any portion thereof, may be
deferred by a Grantee until such time as the Committee may establish. All such deferrals shall be accomplished by the delivery of a written, irrevocable election by the Grantee at such times prior to the time payment would otherwise be made as the
Committee shall determine. All deferrals shall be made in accordance with such rules and regulations established by the Committee to ensure that such deferrals comply with all applicable requirements of the Code and its regulations. Deferred
payments shall be paid in a lump sum or installments, as determined by the Committee. The Committee also may credit interest at such rates to be determined by the Committee. 

SECTION 20.2 DESIGNATION OF BENEFICIARY 

Each Grantee shall file with the Company a written designation of one or more persons as the Beneficiary who shall be entitled to receive the
Award, if any, payable under the Plan upon his death. A Grantee may from time to time revoke or change his Beneficiary designation without the consent of any prior Beneficiary by filing a new designation with the Company. The last such designation
received by the Company shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Company prior to the Grantee’s death, and in no event shall it be effective as of a
date prior to such receipt. If no such Beneficiary designation is in effect at the time of a Grantee’s death, or if no designated Beneficiary survives the Grantee or if such designation conflicts with law, the Grantee’s estate shall be
entitled to receive the Award, if any, payable under the Plan upon his death. If the Committee is in doubt as to the right of any person to receive such Award, the Company may retain such Award, without liability for any interest thereon, until the
Committee determines the rights thereto, or the Company may pay such Award into any court of appropriate jurisdiction and such payment shall be a complete discharge of the liability of the Company therefor. 

SECTION 20.3 NO RIGHT TO AN AWARD OR TO CONTINUED EMPLOYMENT 

No Grantee or other person shall have any claim or right to be granted an Award under the Plan. Neither the action of the Company in
establishing this Plan, nor any provisions hereof, nor any action taken by the Company, any Participating Subsidiary, the Committee or the CEO (or his designee or designees) pursuant to such provisions shall be construed as creating in any employee
or class of employees any right with respect to continuation of employment by the Company or any of the Participating Subsidiaries, and they shall not be deemed to interfere in any way with the Company’s or any Participating Subsidiary’s
right to employ, discipline, discharge, terminate, lay off or retire any Grantee with or without cause, to discipline any Employee, or to otherwise affect the Company’s right to make employment decisions with respect to any Grantee. 

SECTION 20.4 DISCRETION OF THE COMMITTEE AND THE CEO 

Whenever the terms of the Plan provide for or permit a decision to be made or an action to be taken by a Grantor, such decision may be made or
such action taken in the sole and absolute discretion of such Grantor and shall be final, conclusive and binding on all persons for all purposes; provided, however, that the Board may review any decision or action of the Grantor and if the Board
determines that any Award or other decision or act of the Grantor is inequitable or contrary to the provisions of this Plan, it may reverse or modify such Award, decision or act. As provided in Section 16.2 in the case of the Grantor’s
determinations under the Plan, including, without limitation the determination of the person to receive awards and the amount of such awards, need not be uniform and may be made by him selectively among persons who receive, or are eligible to
receive, awards under this Plan, whether or not such persons are similarly retired. 

  
 37 








 SECTION 20.5 INDEMNIFICATION AND EXCULPATION 

20.5.1 Indemnification. Each person who is or shall have been a member of the Committee and each director, officer or employee of the Company
or any Participating Subsidiary to whom any duty or power related to the administration or interpretation of this Plan may be delegated, shall be indemnified and held harmless by the Company against and from any and all loss, cost, liability or
expense that may be imposed upon or reasonably incurred by him in connection with or resulting from any claim, action, suit or proceeding to which he may be or become a party or in which he may be or became involved by reason of any action taken or
failure to act under this Plan and against and from any and all amounts paid by him in settlement thereof (with the Company’s written approval) or paid by him in satisfaction of a judgment in any such action, suit or proceeding, except a
judgment in favor of the Company based upon a finding of his bad faith; subject, however, to the condition that upon the institution of any claim, action, suit or proceeding against him, he shall in writing give the Company an opportunity, at its
own expense, to handle and defend the same before he undertakes to handle and defend it on his own behalf. The foregoing right of indemnification shall not be exclusive of any other right to which such person may be entitled under the Company’s
Restated Certificate of Incorporation, as a matter of law or otherwise, or any power that the Company may have to indemnify him or hold him harmless. 

20.5.2 Exculpation. Each member of the Committee, and each director, officer and employee of the Company or of any Participating Subsidiary
shall be fully justified in relying or acting upon in good faith any information furnished in connection with the administration of this Plan by any appropriate person or persons other than himself. In no event shall any person who is or shall have
been a member of the Committee, or a director, officer or employee of the Company or any Participating Subsidiary be liable for any determination made or other action taken or any omission to act in reliance upon such report or information, for any
action (including the furnishing of information) taken or any failure to act, if in good faith. 
 SECTION 20.6 UNFUNDED PLAN 

This Plan is intended to constitute an unfunded, long-term incentive compensation plan for certain selected employees. No special or separate
fund shall be established and no segregation of assets shall be made to assure payment of such amounts, except as expressly set forth in the Plan with respect to Restricted Stock or Performance Shares held in custody accounts. The Company may, but
shall not be obligated to, acquire shares of its Common Stock from time to time in anticipation of its obligations under the Plan, but no Grantee shall have any right in or against any shares of stock so acquired. All such stock shall constitute
general assets of the Company and may be disposed of by the Company at such time and for such purposes as it may deem appropriate. No obligation or liability of the Company to any Grantee with respect to any right to receive a distribution or
payment under the Plan shall be deemed to be secured by any pledge or other encumbrance on any property of the Company. 
 SECTION 20.7
INALIENABILITY OF RIGHTS AND INTERESTS 
 The rights and interests of a Grantee under this Plan are personal to the Grantee and to any person
or persons who may become entitled to distribution or payments under the Plan by reason of death of the Grantee, and the rights and interests of the Grantee or any such person (including, without limitation, any Award distributable or payable under
the Plan) shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any such attempted action shall be void and no such benefit or interest shall be any manner liable for or
subject to debts, contracts, liabilities, engagements or torts of any Grantees. If any Grantee shall attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge any of his rights or interests under the Plan, (including
without limitation, any Award payable under the Plan) then the Committee may hold or apply such benefit or any part thereof to or for the benefit of such Grantee or his Beneficiary, his spouse, children, blood relatives or other dependents, or any
of them, in such manner and in such proportions as the Committee may consider proper. 

  
 38 








 SECTION 20.8 AWARDS NOT INCLUDABLE FOR BENEFIT PURPOSES 

Payments received by a Grantee pursuant to the provisions of the Plan shall not be included in the determination of benefits under any pension,
group insurance or other benefit plan applicable to the Grantee which are maintained by the Company or any of its Subsidiaries, except as may be determined by the Board. 

SECTION 20.9 NO ISSUANCE OF FRACTIONAL SHARES 

The Company shall not be required to deliver any fractional share of Common Stock but, as determined by the Committee, may pay in lieu thereof,
except as otherwise provided in this Plan, the Fair Market Value (determined as of the date of payment the restrictions terminate) of such fractional share to the Grantee or the Grantee’s beneficiary, as the case may be. 

SECTION 20.10 MODIFICATION FOR OVERSEAS GRANTEES 

Notwithstanding any provision to the contrary, the Committee may incorporate such provisions, or make such modifications or amendments in Award
Commitments of Grantees who reside or are employed outside of the United States of America, or who are citizens of a country other than the United States of America, as the Committee deems necessary or appropriate to accomplish the purposes of the
Plan with respect to such Grantee in light of differences in applicable law, tax policies or customs, and to ascertain compliance with all applicable laws. 

SECTION 20.11 LEAVES OF ABSENCE 

The Committee shall be entitled to make such rules, regulations and determinations as it deems appropriate under the Plan in respect of any
leave of absence taken by the recipient of any Award. Without limiting the generality of the foregoing, the Committee shall be entitled to determine (a) whether or not any such leave of absence shall constitute a termination of employment within the
meaning of the Plan and, (b) the impact, if any, of any such leave of absence on awards under the Plan theretofore made to any recipient who takes such leave of absence. 

SECTION 20.12 COMMUNICATIONS 

20.12.1 Communications by the Committee. All notices, statements, reports and other communications made, delivered or transmitted to a Grantee,
Beneficiary or other person under this Plan shall be deemed to have been duly given, made or transmitted when delivered to, or when mailed by first-class mail, postage prepaid and addressed to, such Grantee, Beneficiary or other person at his
address last appearing on the records of the Committee. 
 20.12.2 Communications by the Participants and Others. All elections,
designations, requests, notices, instructions and other communications made, delivered or transmitted by the Company, a Participating Subsidiary, Grantee, Beneficiary or other person to the Committee required or permitted under this Plan shall be in
such form as is prescribed from time to time by each such Committee, shall be mailed by first-class mail or delivered to such location as shall be specified by each such Committee, and shall be deemed to have been given and delivered only upon
actual receipt thereof by such Committee at such location. 
 SECTION 20.13 PARTIES IN INTEREST 

The provisions of the Plan and the terms and conditions of any Award shall, in accordance with their terms, be binding upon, and inure to the
benefit of, all successors of each Grantee, including, without limitation, such Grantee’s estate and the executors, administrators, or trustees thereof, heirs and legatees, and any receiver, trustee in bankruptcy or representative of creditors
of such Grantee. The obligations of the Company under the Plan shall be binding upon the Company and its successors and assigns. 

  
 39 








 SECTION 20.14 SEVERABILITY 

Whenever possible, each provision in the Plan and every Award at any time granted under the Plan shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of the Plan or any Award at any time granted under the Plan shall be held to be prohibited by or invalid under applicable law, then (a) such provision shall be deemed amended to
accomplish the objectives of the provision as originally written to the fullest extent permitted by law, and (b) all other provisions of the Plan and every other Award at any time granted under the Plan shall remain in full force and effect. 

SECTION 20.15 COMPLIANCE WITH LAWS 

The Plan and the grant of Awards shall be subject to all applicable Federal and state laws, rules and regulations and to such approvals by any
government or regulatory agency as may be required. It is intended that the Plan be applied and administered in compliance with Rule 16b-3. If any provision of the Plan would be in violation of Rule 16b-3 if applied as written, such provision shall
not have effect as written and shall be given effect so as to comply with Rule 16b-3, as determined by the Committee. The Board is authorized to amend the Plan and to make any such modifications to Award Commitments to comply with Rule 16b-3, and to
make any such other amendments or modifications as it deems necessary or appropriate to better accomplish the purposes of the Plan in light of any amendments made to Rule 16b-3. 

SECTION 20.16 NO STRICT CONSTRUCTION 

No rule of strict construction shall be implied against the Company, the Committee, the CEO or any other person in the interpretation of any of
the terms of the Plan, any Award granted under the Plan or any rule or procedure established by the Committee.

 This document contains all of the provisions of the Plan and no provisions may be waived, modified or otherwise altered except in a
writing adopted by the Board. 
 SECTION 20.18 GOVERNING LAW
