 HERCULES INCORPORATED 

NONEMPLOYEE DIRECTOR 

STOCK ACCUMULATION PLAN 
  

	I.	PURPOSES 

 Hercules Incorporated (“Company”), by means of this Hercules
Incorporated Nonemployee Director Stock Accumulation 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”), seeks to attract and retain persons of exceptional
ability to serve as directors and to solidify the common interests of its directors and stockholders in enhancing the value of the common stock issued by the Company. 
  

	II.	EFFECTIVE DATE AND TERM 

 This Plan shall be effective as of the date it is
approved by the holders of at least a majority of the shares of the Company’s issued and outstanding common stock present or represented and entitled to vote at the 1993 Annual Meeting of Stockholders (“Effective Date”). The Plan
shall terminate on April 30, 2001. 
  

	III.	DEFINITIONS 

 Words and phrases used in this Plan with an initial capital letter
(other than those specifically defined elsewhere herein) shall have, unless their context clearly indicates to the contrary, the respective meanings set forth in Article X. 
  

	IV.	ELIGIBILITY 

 Each member of the Company’s Board of Directors
(“Board”) in service from time to time shall be eligible to participate in this Plan, provided he or she, as of the date of an award or exchange, is not and has not been an employee of the Company or any of its Subsidiaries
(“Director”). 








	V.	SHARES AVAILABLE FOR THE PLAN 

 5.1 Shares that may be purchased and/or exchanged
under or pursuant to this Plan shall be common stock, $25/48 stated value per share, authorized and issued by the Company (“Common Stock”). Such shares are to be made available (i) for options granted hereunder, from authorized but
unissued shares of Common Stock or from shares of Common Stock reacquired by the Company (including shares purchased in the open market), or both, at the discretion of the Company, and (ii) for deferral fee exchanges hereunder, from shares of
Common Stock reacquired by the Company (including shares purchased in the open market). 
 5.2 Subject to adjustments as provided in
Section 5.4, the maximum aggregate number of shares of Common Stock for which options may be granted under Article VI (“Options”) shall be one hundred fifty thousand (150,000) shares and the maximum aggregate number of shares of
Common Stock that may be exchanged pursuant to Section 7.4 for director fees under Article VIII (“Deferral Exchanges”) shall be thirty thousand (30,000) shares. 

5.3 In the event that any unexercised Option (or any portion thereof) granted under Article VI shall expire, terminate or be canceled for any
reason, the shares of Common Stock so affected shall be available for use under the Plan to the same person or to other persons by way of any option authorized under the Plan. 

5.4 In the event that the outstanding shares of Common Stock are changed into or exchanged for a different number or kind of shares of the
Company or other securities of the Company or a successor entity by reason of merger, consolidation, corporate reorganization, recapitalization, reclassification, stock dividend, stock split, split-up, split-off or spin-off, combination or exchange
of shares, or otherwise, the Board may (i) make such adjustments, if any, as it deems appropriate in the number, kind and purchase price or exchange value of shares subject to the Plan or to outstanding Options and (ii) take such other
action as in its opinion is appropriate under the circumstances. Without limiting the foregoing, the Board may make an appropriate adjustment to each outstanding Option such that each such Option shall thereafter be exercisable for such shares,
securities, cash and/or other property as would have been received in respect of the shares subject to such Option had such Option been exercised in full immediately prior to such change, and such an adjustment shall be made successively each time
any such change shall occur. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 2










	VI.	OPTIONS 

 6.1 Subject to the maximum number of shares of Common Stock that may be
purchased pursuant to the exercise of Options, as set forth in Section 5.2 (as such number may be adjusted pursuant to the provisions of Section 5.4), an Option to purchase 1,000 shares of Common Stock (“Option Shares”), in the
manner and subject to the terms and conditions hereinafter provided, shall be granted each year, automatically and without further action by the Board or the Committee, as of the third (3rd) business day following the date on which the Company
releases for publication its third (3rd) quarter statement of sales and earnings, to each person who is serving as an eligible director of the Company on such date. 

6.2 Each Option shall be subject to all of the terms, conditions and restrictions provided in this Plan and such other terms, conditions and
restrictions, if any, as may be specified by the Committee with respect to the Option in question at the time of the granting of the Option or as may be specified thereafter by the Committee in the exercise of its powers under the Plan. Without
limiting the foregoing, it is understood that the Committee may, at any time and from time to time after the granting of an Option hereunder, specify such additional terms, conditions and restrictions with respect to such Option as may be deemed
necessary or appropriate to ensure compliance with any and all applicable laws, including, but not limited to, terms and conditions for compliance with federal and state securities laws and methods of withholding or providing for the payment of
required taxes. The terms, conditions and restrictions with respect to any Option, or with respect to any Option to any optionee Director, need not be identical with the terms, conditions and restrictions with respect to any other Option, or with
respect to any Option to any other optionee Director. Each Option granted pursuant to the Plan shall be evidenced by an Option Agreement in such form as the Committee shall from time to time approve. Such Agreement shall conform with, and be subject
to, the provisions of the Plan. The Option Agreement shall not be a precondition to the granting of Options; however, no person shall have any rights under any Option granted under the Plan unless and until the optionee Director to whom such Option
shall have been granted shall have executed and delivered to the Company an Option Agreement. A fully executed original of the Option Agreement shall be provided to both the Company and the optionee Director. 

6.3 All Options shall be nonstatutory options, not intended to qualify as stock options entitled to special tax treatment under
Section 422A of the Code, as defined hereinafter. 
 6.4 In the event that the number of Option Shares available for grants under the
Plan is insufficient to make all grants hereby specified on the applicable date, then all directors who are entitled to a grant on such date shall share ratably in the number of Option Shares then available for grant under the Plan. 

6.5 Each Option shall be exercisable at any time or times as to all or part of the shares of Common Stock covered thereby prior to the
expiration of ten (10) years from the date of grant thereof, subject to the limitations of Section 6.7 and to the provisions of Section 6.14. To the extent that an Option is not exercised within the ten (10) year period of
exercisability specified in this Section 6.5 (“Option Period”), it shall expire as to the then unexercised part. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 3









 6.6 The purchase price per share at which the optionee Director may buy Option Shares upon
exercise of the Option (“Option Price”) shall be 100% of the Fair Market Value per share of Common Stock at the date the Option is granted, subject to adjustment as provided in Section 5.4; provided, however, that in no event shall
the Option Price be less than the stated value of Common Stock. 
 6.7 Each Option shall be subject to the following additional restrictions
on exercisability: 
 a. The Option is not immediately exercisable. Except in the event of an optionee Director’s death,
Disability or Retirement, an Option shall not be exercisable, in whole or in part, prior to the expiration of one (1) year from the date of grant. In no event may an Option be exercised prior to the expiration of six (6) months from date
of grant. 
 b. An Option may be exercised only during the period beginning on the third (3rd) business day following
the date on which the Company releases for publication its quarterly or annual summary statements of sales and earnings and ending on the twelfth (12th) business day following such date (“Exercise Period”). 

c. An Option shall not be exercisable with respect to a fractional share or with respect to fewer than ten (10) Option
Shares (or the remaining Option Shares then subject to the Option, if fewer than ten). 
 d. Except as provided in Sections
6.14 and 11.1, an Option shall not be exercisable in whole or in part unless the optionee Director, at the time he or she exercises the Option, is, and has been at all times since the date of grant of the Option, a director of the Company. 

e. If at any time the Board shall determine, in its discretion, that the listing, registration or qualification of Option
Shares upon any national securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of, or in connection with, the granting of an Option or the sale
or purchase of Option Shares thereunder, such Option may not be exercised in whole or in part unless and until such listing, registration, qualification, consent or approval shall have been effected or obtained, or otherwise provided for, free of
any conditions not acceptable to the Board in the exercise of its reasonable judgment. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 4









 6.8 Subject to the limitations of Section 6.7 and other terms and conditions of this Plan,
an optionee Director may exercise an Option, in whole or from time to time in part, by giving written notice of exercise to the Company at its office at Hercules Plaza, Wilmington, Delaware, 19894, to the attention of the Secretary of the Company.
Such notice shall be on a form approved by the Committee and shall state the election to exercise the Option, the number of Option Shares in respect of which it is being exercised and a business day not more than fifteen (15) days from the date
such notice is given for the payment of the purchase price against delivery of the shares of Common Stock being purchased. The notice shall be signed by the person or persons exercising the Option, and must be received by the Company’s
Secretary on or before the expiration date of the Option. If an Option shall be exercised by a legal representative of a deceased optionee Director or by a person who acquired an Option by bequest or inheritance by reason of a deceased optionee
Director, written notice of such exercise shall be accompanied by a certified copy of letters testamentary or equivalent proof of authority of such legal representative or other person or persons to exercise such Option and evidence satisfactory to
the Company that any death taxes payable with respect to such shares have been paid or provided for. 
 6.9 Payment for Option Shares
purchased under any exercise of an Option shall be made in full concurrently with the exercise of the Option. The optionee Director shall pay for Option Shares purchased under any Option exercise in cash, by check or, with the Committee’s
permission, by delivering shares of Common Stock already owned by the optionee Director, duly assigned to the Company with the assignment guaranteed by a bank, trust company or member firm of the New York Stock Exchange, or a combination of the
foregoing. The shares delivered in payment for the Option Shares being acquired shall have a Fair Market Value on the date of exercise equal to the aggregate Option Price for all Option Shares being acquired. The Committee shall determine acceptable
methods for tendering shares of Common Stock as payment upon exercise of an Option and may impose such limitations and restrictions on the use of shares of Common Stock to exercise an Option as it deems appropriate. The Committee may also permit
payment in accordance with a cashless exercise program under which, if so instructed by the optionee Director, shares of Common Stock may be issued directly to the optionee Director’s broker or dealer upon receipt of the purchase price in cash
from the broker or dealer. 
 6.10 Promptly after exercise of the Option, payment in full of the aggregate Option Price and compliance with
all applicable requirements and conditions of the Plan, the Option Agreement and such rules and regulations as may be established by the Committee that are preconditions to delivery, the Company shall effect the issuance of such number of Option
Shares as are subject to the Option exercise. A certificate or certificates for the Option Shares as to which the Option has been exercised shall be issued by the Company in the name of the person exercising the Option and shall be delivered to or
upon the written order of such person or persons 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 5









 
exercising the Option; provided, however, the Company shall not be required to deliver any certificate upon the exercise of an Option until it has been furnished with such opinion of counsel,
representation or other document as it may reasonably deem necessary to insure compliance with any state or federal securities law and/or rule or regulation of the Securities and Exchange Commission or other governmental authority having
jurisdiction, including, without limitation, the representations and documentation required by Section 11.3. The Company shall pay all issue taxes with respect to the issuance of Option Shares, as well as all fees and expenses necessarily
incurred by the Company in connection with such issuance. All Option Shares issued as provided herein shall be fully paid and nonassessable to the extent permitted by law. 

6.11 An Option by its terms shall not be transferable, whether by operation of law or otherwise, other than by will or the laws of descent and
distribution, and any such Option shall be exercisable during the optionee Director’s lifetime only by the optionee Director or the optionee Director’s guardian or legal representative. Any attempted assignment, transfer, pledge,
hypothecation or other disposition of the Option contrary to the provisions hereof and the levy of any execution, attachment or similar process upon the Option shall be null and void and without effect. 

6.12 Notwithstanding any other provision of the Plan, in no event shall Option Shares issued upon exercise of an Option be sold or otherwise
transferred or hypothecated prior to the expiration of six (6) months from the date of the grant of the Option pursuant to which the shares were acquired. 

6.13 The optionee Director (or any legal representative, guardian, legatee or distributee of such optionee Director) shall not be nor deemed
to be a holder of any Option Shares and shall have no rights or privileges of a stockholder in respect to any Option Shares issuable upon exercise of the Option unless and until such Option Shares have been paid for in full and have been transferred
to him or her on the books and records of the Company upon exercise of the Option. 
 6.14 An Option shall terminate upon the termination,
for any reason, of the optionee Director’s directorship with the Company, and no Option Shares may thereafter be purchased under such Option except as follows: 

a. Upon retirement as a director of the Company pursuant to the Company’s retirement policy for directors, each unexpired
Option held by the optionee Director shall become immediately exercisable and shall remain exercisable, in whole or in part, for a period of three (3) years from the date of such retirement. 

b. An optionee Director may exercise, within one (1) year after termination as a director of the Company due to
Disability, all or part of any Options which he or she was entitled to exercise immediately prior to such termination. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 6









 c. Upon the death of an optionee Director or upon the death of a retired optionee
Director within three (3) years following retirement as a director of the Company, all or part of any Options which such optionee Director was entitled to exercise immediately prior to death may be exercised within the longer of either the
three (3) years following optionee Director’s retirement or one (1) year after his or her death by a person or persons (including optionee Director’s legal representatives, distributees, or legatees) to whom the rights of the
deceased optionee Director under the Option shall pass by will or the laws of descent and distribution. 
 Again, in no event may any Option
be exercised (i) prior to the expiration of six (6) months from the date of grant, or (ii) after ten (10) years from the date it was granted. 
  

	VII.	DEFERRAL EXCHANGES 

 7.1 By written notice received by the Secretary of the
Company not later than December 15 preceding the beginning of any calendar year, a Director may elect to defer all or a portion of the Director Fees that may be payable to him or her for services rendered during such calendar year
(“Deferred Fees”) and to have such Deferred Fees invested for his or her account under the terms of this Article VII. A Director may elect to defer (i) all of his or her total Director Fees for the calendar year, (ii) any portion
thereof in multiples of twenty-five percent (25%), or (iii) a flat annual dollar amount not in excess of his or her total Director Fees for the calendar year. An election must be made in this manner for each year for which the Director wishes
to defer payment of any Director Fees. 
 7.2 At the time of his or her election to defer payment of Directors Fees pursuant to
Section 7.1, the Director also must specify the amount or percentage, in multiples of twenty-five percent (25%), of his or her Deferred Fees to be applied to one or both of a cash deferral program (“Cash Program”) or a stock exchange
program (“Equity Program”), each as is further described, respectively, in Sections 7.3 and 7.4 herein. 
 7.3 Under the Cash
Program: 
 (a) A Director electing to have all or a portion of his/her Deferred Fees invested in the Cash Program shall have
credited to an unfunded bookkeeping cash account established and maintained by the Company in respect of such Director to record and account for cash deferrals until such time as the account 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 7









 
balance is distributed in accordance with the provisions of either paragraph (d) or (e) of this Section 7.3 (“Cash Account”), on each Deferral Date, such designated
amounts. If a Director elects to defer less than one hundred percent (100%) of his Director Fees, deferrals pursuant to either of the other alternatives of Section 7.1 shall be deducted by the Company on a pro-rata basis from the regular
quarterly payments of Director Fees. 
 (b) At the end of each calendar quarter, interest shall be credited to a
Director’s Cash Account based on the average prime rate of interest (as changed from time to time for that quarter) charged by Morgan Guaranty Trust Company of New York. This interest shall be credited on all monies in the Cash Account at the
end of each quarter. A Director’s Cash Account shall continue to accrue interest in this manner until the final distribution thereof is made to the Director in accordance with either paragraph (d) or (e) of this Section 7.3. 

(c) Concurrent with the election to participate in the Cash Program, the Director must elect to receive the distribution of the
balances in his or her Cash Account: 
 (i) in either a single payment or in forty (40) quarterly installments, each
such installment to be determined by dividing the current value of the Deferred Fees plus earnings thereon by the number of installment payments (including the payment being made) remaining to be paid; and 

(ii) commencing, at his or her election, either on the last day of the calendar quarter following the quarter in which the
Director retires or resigns or otherwise terminates his or her service as a director of the Company, or an anniversary of such date, provided, however, that such commencement date shall in no event be later than the fifth (5th) calendar year
following the calendar year in which the Director retires. 
 (d) A Director’s interest in his/her Cash Account shall
be distributed to him or her (or his/her Beneficiaries, legal representatives, distributees or legatees, as appropriate) in accordance with his/her election made pursuant to paragraph (c) next above. If a single payment has been elected, the
entire cash value of a Director’s account on the distribution date will be paid in a single payment. Where quarterly installments have been elected, the cash value of the portion of the Director’s account balance to be distributed on such
date, including accrued interest thereon, shall be paid to the Director on each quarterly installment distribution date. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 8









 (e) If a Director dies before all or any portion of his/her Cash Account has been
distributed to him or her, the entire balance of the Cash Account shall be paid promptly in a lump sum to such Director’s designated beneficiary or to his/her estate. A Director who terminates his/her services by reason of Disability before all
or any portion of his/her Cash Account has been distributed to him or her, the entire balance of the Cash Account shall be paid according to his/her irrevocable election in a lump sum or in installment payments commencing on the last day of the
quarter after the quarter in which he or she terminates his/her service on the Board. 
 7.4 Under the Equity Program: 

(a) A Director electing to have all or a portion of his/her Deferred Fees invested in the Equity Program shall have credited to
an equity account established and maintained by the Company in respect of such Director to record and account for shares of Common Stock exchanged for the Deferred Fees directed to the Equity Program (“Equity Account”), on the third
(3rd) business day following the Company’s public announcement of its annual earnings for the prior year, a dollar amount equal to the anticipated aggregate amount of his/her Deferred Fees (exclusive of any amounts that may be payable for
attendance at meetings other than regularly scheduled meetings) otherwise subsequently payable during the calendar year but deferred by the Director under this Article VII and designated for the Equity Program. Such crediting shall be subject to the
adjustment provision of paragraph (e) of this Section 7.4. 
 (b) Simultaneously with the crediting pursuant to
paragraph (a) next above, the Company shall exchange the then cash balance of the Director’s Equity Account for that number of whole shares of Common Stock that equals the number of whole shares of Common Stock obtained by dividing the
dollar value of the exchange amount by eighty-five percent (85%) of the Fair Market Value of Common Stock on the Exchange Date. Each share of Common Stock received as a result of such an exchange (“Exchanged Share”) shall be subject
to the following terms, conditions and restrictions: 
 (i) A stock certificate representing the number of Exchanged Shares
shall be registered in the Director’s name but shall be held in custody by the Company for the Director’s account until distributed as herein provided. The Company shall not be required to deliver any certificate with respect to any
Exchanged Shares until it has been furnished with such opinion of counsel, representation or other document as it may reasonably deem necessary to insure compliance with any state or federal securities law and/or rule or regulation of the Securities
and Exchange Commission or other governmental authority having jurisdiction, including, without limitation, the representations and documentation required by Section 11.3. Except as otherwise provided


  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 9









 
in clause (ii), next below, during the Restricted Period the Director shall have all of the rights and privileges of a stockholder with respect to Exchanged Shares, including, but not limited to,
the right to receive such dividends, if any, as may be declared on such shares from time to time, and the right to vote (in person or by proxy) such shares at any meeting of stockholders of the Company. Dividends and other distributions, if any, on
shares of Common Stock shall be paid directly to the Director. 
 (ii) An Exchanged Share may not be sold, transferred,
assigned, pledged, hypothecated or otherwise encumbered or disposed of (collectively, “assignment or transfer”) until death, Disability or Retirement of the Director (“Restricted Period”), and any attempted assignment or
transfer, whether made or created by a voluntary act of the Director or any agent of such Director or by operation of law, shall not be recognized by, or be binding upon, or shall not affect in any manner the rights of, the Company while holding
certificates for such shares during the applicable Restricted Period pursuant to the provisions of this Section 7.4. 

(c) Upon crediting a Director’s Equity Account in accordance with this Section 7.4, the Company, throughout the
continuance of the calendar year and only to the extent of the Deferred Fees designated for the Equity Program, shall have no further obligation to pay the Director Director Fees (exclusive of any amounts that may be payable for attendance at
meetings other than regularly scheduled meetings) otherwise payable in respect of services rendered to the Company as a director. 

(d) Any Deferred Fees in respect of meetings not regularly scheduled shall be credited to the Director’s Cash Account. Any
cash equal to less than the price of a whole share of Common Stock also shall be credited to the Director’s Cash Account. 

(e) Notwithstanding anything in this Section 7.4 to the contrary, 

(i) in the event a director fails to attend one or more regularly scheduled Board or Board committee meetings, and therefore
does not perform the services for which the anticipated Deferral Fees are payable, at the end of the calendar quarter in which such failure(s) occurred the balance of his/her Equity Account shall be decreased by that number of shares of Common Stock
acquired by Deferral Fees anticipated with respect to the meeting(s) not attended and his/her Equity Account shall be debited with an amount equal to any and all dividends paid on such shares; 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 10









 (ii) if the number of shares for which Directors desire to exchange during any
calendar year exceeds the number of shares then available under this Plan, the shares available shall be allocated proportionally among such Directors. 

(f) If a Director terminates his/her service as a director of the Company, by reason of death, Disability or Retirement before
all or any portion of his/her Equity Account has been distributed to him or her, the entire balance of the Equity Account, subject to adjustment as provided in paragraph (e) next above, shall be distributed to the Director (or his or her
Beneficiaries, legal representatives, distributees or legatees) as soon as administratively practicable. In the event of termination for reasons other than death, Disability or Retirement, any and all shares of Common Stock credited to the Equity
Account will be forfeited. In such cases, the Director shall receive a payment equal to the lesser of (i) Fair Market Value as of the date of termination of service multiplied by the number of shares of Common Stock forfeited, subject to
adjustment as provided below, or (ii) the purchase price paid by the Director for such shares, plus any balance remaining in the Equity Account. 

(g) Upon termination of his/her service as a director of the Company for any reason, the Company may offset any debits pursuant
to paragraph (e) of this Section 7.4 against any amounts otherwise payable in respect of a Cash Account maintained for the Director. If no offset is available, the Director shall promptly remit to the Company the cash equivalent of such
debits. 
 7.5 Deferral and investment elections made under this Article VII with respect to any calendar year (which shall be on such forms
as may be prescribed by the Committee from time to time) shall be final and, after commencement of such calendar year, cannot be amended or revoked in respect of Director Fees for services rendered during such calendar year. 

7.6 Each Director is solely responsible for his or her decision to defer all or a portion of his or her Director Fees and accepts all
investment risk entailed by his selection of an investment program, including the risk of loss due to a decrease in the value of his Deferred Fees. 

7.7 Except for the shares of Common Stock exchanged under paragraph (b) of Section 7.4, the Company shall not be required to reserve
or otherwise set aside any cash or other property as a separate trust for the payment of any amounts credited to any account created hereunder. Except for such shares, the sole obligation of the Company to any Director participating in the deferral
of fees under this Plan is a contractual obligation to make payments in accordance with the terms and conditions set forth in this Article VII. Any fees deferred under the Cash Program provisions of this Plan shall continue for all purposes to be
part of the general funds 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 11









 
of the Company and subject to the claims of general creditors of the Company, and no other person other than the Company shall by virtue of the provisions of the Plan have any interest in such
deferred fees. Nothing contained in this Plan and no action taken pursuant to the Plan shall create or be considered to create a trust of any kind or a fiduciary relationship between the Company and the Director, his or her heirs, successors or any
other person, other than the custodial relationship in respect of Exchanged Shares held by the Company during the Restricted Period. To the extent that any person acquires a right to receive cash payments from the Company under or pursuant to this
Article VII, such right shall be no greater than the right of a unsecured general creditor of the Company. 
  

	VIII.	ADMINISTRATION 

 8.1 Responsibility and authority to administer and interpret the
provisions of the Plan shall be conferred upon a committee designated by the Board (as constituted from time to time, the “Committee”), having full authority to act, which Committee shall not have fewer than three (3) members. 

8.2 The Committee is authorized to interpret the Plan; to prescribe, amend and rescind such rules and regulations not inconsistent with the
provisions of the Plan, as it may deem advisable to carry out the Plan; and to make all other determinations necessary or advisable for administering the plan. The determination of the Committee on matters referred to in this Article VIII shall be
conclusive. 
 8.3 The Committee may employ attorneys, consultants, accountants or other persons, and the Committee, the Company and its
officers, directors and employees shall be entitled to rely upon the advice, opinions or valuations of any such persons in connection with their respective responsibilities and authority hereunder. All usual and reasonable expenses incurred in the
administration and interpretation of the Plan shall be paid by the Company. No member of the Committee shall receive compensation with respect to his/her services on or for the Committee except as may be authorized by the Board. All actions taken
and all interpretations and determinations made by the Committee in good faith shall be final and binding upon all Directors, the Company and other interested persons. Neither the Company, any member of the Committee or any other individual involved
in the administration and/or interpretation of the Plan shall be liable, personally or otherwise, for any action, determination or interpretation taken or made in good faith with respect to the Plan or Options and/or Deferral Exchanges. Each member
of the Committee and each other individual involved in the administration and/or interpretation of the Plan shall be fully indemnified and protected by the Company in respect of any cost or expense or liability arising out of any act or failure to
act in connection with the Plan unless arising out of such person’s own fraud or bad faith.

of the quorum present at any meeting or acts approved in writing by all members of the Committee shall be deemed the acts of the Committee. 

8.5 Notwithstanding anything contained in the Plan to the contrary, the Committee shall have no discretion or authority to (i) determine
which members of the Board are entitled to receive or exercise rights with respect to Options and/or Deferral Exchanges, (ii) grant Options and/or exchange shares other than as provided in the Plan, (iii) determine the number of Options
and/or Deferral Exchanges which may be granted or made available to any Director, (iv) modify the number of shares of Common Stock issuable (subject to Section 5.4) under or pursuant to Options and/or exchangeable (subject to

	IX.	AMENDMENT, SUSPENSION OR TERMINATION OF THE PLAN 

 9.1 The Board may, from time to
time, amend the Plan in any respect, provided that no amendment shall be made without the approval of the stockholders of the Company that will (i) increase the total number of shares of Common Stock available for Options and Deferral Exchanges
under the Plan (other than an increase resulting from an adjustment provided for in Section 5.4, (ii) change the manner of determining the exercise price of the Option or the exchange value for Exchanged Shares, (iii) increase the
maximum term of the Options provided for herein, (iv) modify the provisions of the Plan relating to the eligibility of persons entitled to receive Plan Benefits hereunder, or (v) materially increase benefits accruing to participants under
the Plan; except to the extent that, in the opinion of counsel to the Company, such approval is not required under the Exchange Act or the rules and regulations promulgated thereunder in order for the Options granted under the Plan to continue to be
exempt from the operation of Section 16(b) of the Exchange Act or any successor rule, as it may be amended from time to time. The rights and obligations under any Option and/or Deferral Exchange granted or exchanged, as the case may be, before
amendment of the Plan or under any unexercised portion of such Option shall not be adversely affected by amendment of the Plan or the Option and/or Deferral Exchange without the consent of the holder of the Option and/or Deferral Exchange. 

9.2 The Board reserves the right at any time, to suspend or terminate, in whole or from time to time in part, any or all of the provisions of
the Plan for any reason and without the consent of or approval by the stockholders of the Company, any Director or Beneficiary or any other person; provided, however, that any and all rights and obligations under any Option or Deferral Exchange
granted or effected, as the case may be, while the Plan is in effect shall not be altered or impaired by 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 13









 
suspension or termination of the Plan, except upon the consent of the Director to whom the Option or Deferral Exchange was granted or effected. The power of the Committee to construe and
administer any Options and/or Deferral Exchanges granted or effected prior to the termination or suspension of the Plan nevertheless shall continue after such termination or during such suspension.

	XI.	MISCELLANEOUS 

 11.1 Notwithstanding other provisions of the Plan, in the event of
a Change in Control of the Company: 
 a. All of the Director’s then-outstanding Options shall immediately become
exercisable, unless directed otherwise by a resolution by the Board adopted prior to and specifically relating to the occurrence of such Change in Control. With respect to such outstanding Options, the Director (i) shall have the right at any
time thereafter during the term of such Option to exercise the Option in full notwithstanding any limitation or restriction in any option agreement or in the Plan, and (ii) shall have the right, exercisable by written notice to the Company
within sixty (60) days after the Change in Control, to receive, in exchange for the surrender of the Option or any portion thereof to the extent the Option is then exercisable in accordance with clause (i), an amount of cash equal to the
difference between the fair market value (as determined by the Board) on the date of surrender of the Common Stock covered by the Option or portion thereof that is so surrendered and the aggregate Option Price of such Common Stock under the Option.

 b. All Exchanged Shares and the cash balances of all Cash and/or Equity Accounts shall immediately vest (to the extent
then not fully vested) and become fully payable and/or deliverable to the Director on whose behalf the same are being held. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 16









 11.2 Each Director shall file with the Company a written designation of one or more persons as
the beneficiary (“Beneficiary”) who shall be entitled to receive shares of Common Stock and/or cash, if any, issuable or payable, as the case may be, under the Plan upon his or her death. A Director may from time to time revoke or change
his or her 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 Director’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
Director’s death, or if no designated Beneficiary survives the Director or if such designation conflicts with law, the Director’s estate shall be entitled to receive the shares of Common Stock and/or cash, if any, issuable or payable, as
the case may be, under the Plan upon his or her death. If the Committee is in doubt as to the right of any person to receive such shares of Common Stock and/or cash, the Company may retain such assets, without liability for any interest thereon,
until the Committee determines the rights thereto, or the Company may pay the assets into any court of appropriate jurisdiction and such payment shall be a complete discharge of the liability of the Company therefor. 

11.3 (a) Except as hereafter provided, a Director shall, upon any exercise of an Option or the exchange of Exchanged Shares, execute and
deliver to the Company a written statement, in form satisfactory to the Company, in which he or she represents and warrants that he or she is purchasing or exchanging the Option or Exchanged Shares for his/her own account, for investment only and
not with a view to the resale or distribution thereof, and represents and agrees that any subsequent offer for sale or sale or distribution of any of such shares shall made only pursuant to either (i) a registration statement on an appropriate
form under the Securities Act, which registration statement has become effective and is current with regard to the shares being offered or sold, or (ii) a specific exemption from the registration requirements of the Securities Act, but in
claiming such exemption the holder shall, prior to any offer for sale or sale of such Option shares, obtain a prior favorable written opinion, in form and substance satisfactory to the Company, from counsel for or approved by the Company, as to the
applicability of such exemption thereto. The foregoing restriction shall not apply to (a) issuances by the Company so long as the Option Shares and/or Exchanged Shares being issued or exchanged, as the case may be, are registered under the
Securities Act and a prospectus in respect thereof is current or (b) reofferings of Option or Exchanged Shares by affiliates of the Company (as defined in Rule 405 or any successor rule or regulation promulgated under the Securities Act) if the
shares being reoffered are registered under the Securities Act and a prospectus in respect thereof is current. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 17









 (b) The Company may endorse such legend or legends upon the certificates for Option or Exchanged
Shares issued or exchanged hereunder and may issue such “stop transfer” instructions to its transfer agent in respect of such shares as, in its discretion, it determines to be necessary or appropriate to (i) prevent a violation of, or
to perfect an exemption from, the registration requirements of the Securities Act, or (ii) implement the provisions of the Plan and any agreement between the Company and the optionee Director with respect to such shares. 

11.4 Neither the action of the Company in establishing this Plan, nor any provisions hereof, nor any action taken by the Company or the
Committee pursuant to such provisions, shall be construed as creating any rights (or impose any obligations) with respect to continuance as a director of the Company, nor shall they be deemed to interfere in any way with any right of the Company to
terminate at any time the Director’s position as a director of the Company. 
 11.5 Notwithstanding any other provision of the Plan,
each Option granted to a Director and all rights of the Director to receive Options under the Plan shall be forfeited if a Director (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 the Director 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 11.4 shall be conclusive
and binding upon all persons for all purposes. 
 11.6 Any notice or other communication required or permitted under the Plan to the Company
shall be addressed to it at its office, Hercules Plaza, Wilmington, Delaware 19894, attention: Corporate Secretary; and any notice or other communication required or permitted under the Plan to Director shall be addressed to him or her at such
location as shall be designated by the Director in writing. Any such notice shall be deemed given when personally delivered or when mailed by United States registered or certified mail, return receipt requested, postage prepaid. The foregoing is
subject to the right of the Company and of the Director to designate at any time, in writing, some other address. 
 11.7 The provisions of
the Plan and the terms and conditions of any Plan Benefit shall, in accordance with their terms, be binding upon, and inure to the benefit of and be enforceable by, the Director’s personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. The obligations of the Company under the Plan shall be binding upon the Company and its successors and assigns. 

  

			
	Nonemployee Director Stock Accumulation Plan	  	Page 18









 11.8 Whenever possible, each provision in the Plan and every Plan Benefit shall be interpreted in
such manner as to be effective and valid under applicable law, but if any provision of the Plan or any Plan Benefit at any time granted under the Plan shall be held by a court of competent jurisdiction to be prohibited by or invalid under applicable
law, then (i) such provision shall be deemed amended to accomplish the objectives of the provision as originally written to the fullest extent permitted by law and (ii) all other provisions of the Plan and every Plan Benefit at any time
granted under the Plan shall remain in full force and effect. 
 11.9 The Plan and the grant, exercise, issue, exchange payment or
distribution, as the case may be, of any Plan Benefit 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 Option Agreements 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. 
 11.10 The Director’s right
to benefits under this Plan shall not be assignable or transferable, whether by pledge, creation of a security interest or otherwise, other than by will or by the laws of descent or distribution. In the event of any attempted assignment or transfer
contrary to this Section 11.10, the attempted assignment or transfer shall be null and void and without effect. 
 11.11 The Company
shall withhold (or secure payment from the Director 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 the Plan,
and it may defer payment or issuance of the cash or stock upon exercise or vesting of a Plan Benefit 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 Treasurer of the Company and shall be payable by the Director at the time of delivery or when payment is made. 
 11.12 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.

related matters shall be governed by, and construed and enforced in accordance with, the laws of the internal laws of the State of Delaware from time to time obtaining.
