Arch Senior Executive Pension Plan II, effective as of October 30, 2009

 Exhibit 10.15 
 ARCH SENIOR EXECUTIVE PENSION PLAN II 
 Article I.
The Plan 
 1.1 Establishment of Plan. Effective as of October 30, 2009, Arch Chemicals, Inc. (the
“Company” or “Arch”) hereby establishes a non-qualified deferred compensation plan known as the Arch Senior Executive Pension Plan II (the “Plan”) for the benefit of certain salaried employees of Arch and other
Employing Companies who may be eligible to participate. 
 1.2 Purpose. The purpose of this Plan is to provide benefits
to certain current and former salaried employees of Arch and other Employing Companies whose benefits under the terms of The Pension Plan of Arch Chemicals are limited (i) by §415 of the Internal Revenue Code of 1986, as amended (the
“Code”), (ii) by the limitations on compensation that can be taken into account in calculating qualified plan benefits under Code §401(a)(17), and (iii) by the inability to include in compensation for Qualified Plan Pension
Benefits any salary and awards of management incentive compensation that have been deferred by eligible employees into non-qualified plans or arrangements. These limitations are collectively referred to herein as “Benefit Limitations.”
This Plan is intended to provide Participants affected by Benefit Limitations (and their beneficiaries) with benefits equal to the difference in value between what such Participants’ benefits under The Pension Plan of Arch Chemicals would be
absent the Benefit Limitations, and what their benefits are taking into account the Benefit Limitations. 
 A further purpose of
this Plan is to attract and retain a management group capable of assuring Arch’s future success by providing them with the opportunity to earn additional supplemental retirement income under this Plan if certain service requirements are met.

 1.3 Eligibility and Participation. Any Arch Employee whose job is rated at 2,000 Hay Points (or the equivalent) or
more and who is selected by the Board of Directors of the Company or the Compensation Committee of the Board (referred to in this Plan as the “Selection Committee”) shall participate in the Plan (a “Participant”). As provided
hereinafter, the Selection Committee shall also have the power to remove any Participant from the Plan, whether or not he or she has begun to receive benefits hereunder. Participation shall be effective as of the date designated by the Selection
Committee. 
 1.4 Nature of Plan. This Plan is divisible into two components: that portion which qualifies for the
exemption from the Employee Retirement Income Security Act (“ERISA”) as an unfunded “excess benefit plan,” and that portion which provides for benefits in excess of applicable compensation limits, and is intended to be an
unfunded supplemental executive retirement plan for a select group of management and highly compensated employees. The Plan is also intended to be a non-qualified deferred compensation plan which meets the requirements of Code §409A(a)(2),
(3) and (4). 

 Article II. Definitions 
 2.1 “Arch Supplementary and Deferral Pension Benefit Plan” means the Arch Supplementary and Deferral Pension Benefit Plan. No
Participant in this Plan shall be eligible to accrue any additional benefits under the Arch Supplementary and Deferral Pension Benefit Plan on or after the date such Participant becomes a Participant in this Plan. 
 2.2 A “Change in Control” with respect to a Participating Employer that is organized as a corporation occurs on the date on
which any of the following events occur (i) a change in the ownership of the Participating Employer; (ii) a change in the effective control of the Participating Employer; (iii) a change in the ownership of a substantial portion of the
assets of the Participating Employer. 
 (a) A change in the ownership of the Participating Employer occurs on the date on which
any one person, or more than one person acting as a group, acquires ownership of stock of the Participating Employer that, together with stock held by such person or group constitutes more than 50% of the total fair market value or total voting
power of the stock of the Participating Employer. A change in the effective control of the Participating Employer occurs on the date on which either (i) a person, or more than one person acting as a group, acquires ownership of stock of the
Participating Employer possessing 30% or more of the total voting power of the stock of the Participating Employer, taking into account all such stock acquired during the 12-month period ending on the date of the most recent acquisition, or
(ii) a majority of the members of the Participating Employer’s Board of Directors is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of such Board of Directors
prior to the date of the appointment or election, but only if no other corporation is a majority shareholder of the Participating Employer. A change in the ownership of a substantial portion of assets occurs on the date on which any one person, or
more than one person acting as a group, other than a person or group of persons that is related to the Participating Employer, acquires assets from the Participating Employer that have a total gross fair market value equal to or more than 80% of the
total gross fair market value of all of the assets of the Participating Employer immediately prior to such acquisition or acquisitions, taking into account all such assets acquired during the 12-month period ending on the date of the most recent
acquisition. 
 (b) An event constitutes a Change in Control with respect to a Participant only if the Participant performs
services for the Participating Employer that has experienced the Change in Control, or the Participant’s relationship to the affected Participating Employer otherwise satisfies the requirements of Treasury Regulation
§1.409A-3(2)(i)(5)(ii). 
 (c) The determination as to the occurrence of a Change in Control shall be based on objective
facts and in accordance with the requirements of Code §409A.

 2.13 “Separation from Service” means a termination of employment with the Company, as defined for purposes of Code §409A. 
 (a) Except as noted below with respect to asset sales, the Plan Administrator will determine, in accordance with Code §409A, whether a
Separation from Service has occurred. Except in the case of a Participant on a bona fide leave of absence as provided below, a Participant is deemed to have incurred a Separation from Service if the Company and the Participant reasonably anticipated
that the level of services to be performed by the Participant after a date certain would be reduced to 20% or less of the average services rendered by the Participant during the immediately preceding 36-month period (or the total period of
employment, if less than 36 months), disregarding periods during which the Participant was on a bona fide leave of absence. 
 (b) An Employee who is absent from work due to military leave, sick leave, or other bona fide leave of absence shall incur a Separation from Service on the first date immediately following the later of (i) the six-month anniversary of
the commencement of the leave, or (ii) the expiration of the Employee’s right, if any, to reemployment under statute or contract. Notwithstanding the preceding, however, with respect to an Employee who is absent from work

  

 3 

 
due to a physical or mental impairment that is expected to result in death or last for a continuous period of at least six months and that prevents the Employee from performing the duties of his
or her position of employment or a similar position, the twenty-nine-month anniversary of the commencement of leave shall be substituted for the six-month anniversary in (i) in the preceding sentence. 
 (c) For purposes of determining whether a Separation from Service has occurred, the Company means the Company and any Affiliate, except that
for purposes of determining whether another organization is an Affiliate of the Company, common ownership of at least 50% shall be determinative. Affiliate means a corporation, trade or business that, together with the Company, is treated as a
single employer under Code §414(b) or (c). 
 (d) The Company specifically reserves the right to determine whether a sale
or other disposition of substantial assets to an unrelated party constitutes a Separation from Service with respect to a Participant providing services to the seller immediately prior to the transaction and providing services to the buyer after the
transaction. Such determination shall be made in accordance with the requirements of Code §409A. 
 2.14 “Specified
Employee” means an employee who, as of the date of his or her Separation from Service, is a “key employee” of the Company or any Affiliate, any stock of which is actively traded on an established securities market or otherwise. An
employee is a key employee if he or she meets the requirements of Code §416(i)(1)(A)(i), (ii), or (iii) (applied in accordance with applicable regulations thereunder and without regard to Code §416(i)(5)) at any time during the
12-month period ending on the Specified Employee Identification Date. Such Employee shall be treated as a key employee for the entire 12-month period beginning on the Specified Employee Effective Date. 
 For purposes of determining whether an Employee is a Specified Employee, the compensation of the Employee shall be determined in accordance
with the definition of compensation provided under Treas. Reg. §1.415(c)-2(d)(3) (wages within the meaning of Code §3401(a) for purposes of income tax withholding at the source, plus amounts excludible from gross income under Code
§§125(a), 132(f)(4), 402(e)(3), 402(h)(1)(B), 402(k) or 457(b), without regard to rules that limit the remuneration included in wages based on the nature or location of the employment or the services performed); provided, however, that,
with respect to a nonresident alien who is not a Participant in the Plan, compensation shall not include compensation that is not includible in the gross income of the Employee under Code §§872, 893, 894, 911, 931 and 933, provided such
compensation is not effectively connected with the conduct of a trade or business within the United States. 
 Notwithstanding
anything in this paragraph to the contrary, (i) if a different definition of compensation has been designated by the Company with respect to another nonqualified deferred compensation plan in which a key employee participates, the definition of
compensation shall be the definition provided in Treas. Reg. §1.409A-1(i)(2), and (ii) the Company may through action that is legally binding with respect to all nonqualified deferred compensation plans maintained by the Company, elect to
use a different definition of compensation. In the event of corporate transactions described in Treas. Reg. §1.409A-1(i)(6), the identification of Specified Employees

  

 4 

 
shall be determined in accordance with the default rules described therein, unless the Employer elects to utilize the available alternative methodology through designations made within the
timeframes specified therein. Specified Employee Effective Date means the first day of the fourth month following the Specified Employee Identification Date, or such earlier date as is selected by the Plan Administrator. Specified Employee
Identification Date means December 31, unless the Employer has elected a different date through action that is legally binding with respect to all nonqualified deferred compensation plans maintained by the Employer. 
 2.15 “Spouse” shall mean the person to whom a Participant is validly married at the date of the Participant’s death and to
whom the Participant was validly married for at least 12 months immediately prior to the Participant’s death, as evidenced by a marriage certificate issued in accordance with state law and as recognized under federal law. Common law marriages
shall not be recognized hereunder. 
 Article III. Benefits 
 3.1 Benefits; In General. Retirement Benefits are payable hereunder upon the first to occur of the following: 
 (a) a Participant’s Normal Retirement Date, as provided in Section 3.3; or 
 (b) a Participant’s Early Retirement Date, as provided in Section 3.4; or 
 (c) a Participant’s Deferred Vested Retirement Date, as provided in Section 3.5. 
 In addition, (i) benefits may be payable in the event of a Change of Control (see Section 3.7, below), and (ii) pre-retirement survivor
benefits may be payable in the event a Participant dies prior to qualifying for Retirement (see Section 3.6(b), below). 
 3.2 Benefit Formula. 
 (a) A Participant’s Retirement Benefit, calculated as of the Participant’s
Separation from Service date, shall equal the benefit calculated under Formula A, plus, if applicable, the benefit calculated under Formula B, below. 
 Formula A. The Retirement Benefit calculated in accordance with Formula A shall be equal to X minus (Y + Z) where: 
  

	 	X =	the value of the Qualified Plan Pension Benefit to which the Participant would have been entitled had such benefit been calculated (i) including non-qualified
deferrals of regular salary and awards under any applicable management incentive plan, and (ii) without regard to the Benefit Limitations; 

  

	 	Y =	the value of the Qualified Plan Pension Benefit payable to the Participant; and 

  

 5 

	 	Z =	the value of the Supplemental Pension Benefit payable to the Participant pursuant to the Arch Supplementary and Deferral Pension Benefit Plan. 

The amounts described, above, shall (i) be calculated in the form of a single life annuity payable over the lifetime of the Participant commencing
at the Participant’s sixty-fifth (65th) birthday or, if later, his or her actual Separation from Service date; (ii) shall, except as provided in (iv), below, be based on the Participant’s service and compensation as of the date
of the Participant’s Separation from Service; (iii) shall reflect the effect of any applicable vesting schedule on the Participant’s Qualified Plan Pension Benefits; and (iv) shall be calculated taking into account the
Participant’s retirement benefit then payable (1) from the Pension Plan of Arch Chemicals using the Benefit Limitations in effect as of the Participant’s Separation from Service date, and (2) from the Arch
Supplementary and Deferral Pension Plan using the service, compensation and Benefit Limitations as of the date the Participant ceases to accrue benefits under such Plan. If a Participant’s Formula A Retirement Benefit becomes payable upon the
Participant’s Early Retirement Date it shall be adjusted using the early retirement reductions specified in the Pension Plan of Arch Chemicals based upon the Participant’s Benefit Commencement Date. If a Participant’s Formula A
Retirement Benefit become payable upon the Participant’s Deferred Vested Retirement Date, it shall be adjusted using the actuarial reductions that would be applicable to deferred vested benefits under The Pension Plan of Arch Chemicals as of
the Participant’s Benefit Commencement Date. 
 Formula B. The Retirement Benefit calculated in accordance with Formula B
shall equal X minus Y. 
 For purposes of Formula B, X is the lesser of (i) or (ii), below, multiplied by the Participant’s Average
Compensation. 
 (i) two percent (2%), multiplied by the Participant’s Years of Benefit Service credited
under the Pension Plan of Arch Chemicals, reduced by one-third of one percent (1/3%) for each month by which the Participant’s benefits under this Plan begin prior to the Participant’s sixty-fifth (65th) birthday; or 

(ii) sixty percent (60%), reduced by one-third of one percent (1/3%) for each month by which the Participant’s
benefits under this Plan begin prior to the Participant’s sixty-fifth (65th) birthday. 
 For purposes of Formula B, Y is the sum of:

 (1) the value of the Qualified Plan Pension Benefit payable to the Participant; and 
 (2) the value of the Supplemental Pension Benefit payable to the Participant pursuant to the Arch Supplementary and
Deferral Pension Benefit Plan; 
 (3) the value of the Participant’s benefit under Formula A,
above; and 
  

 6 

 (4) fifty percent (50%) of the Participant’s Primary Social
Security Benefit. 
 Notwithstanding the foregoing, a Participant shall not vest in a benefit under Formula B until the earliest of the
following dates: (a) the date the Participant attains at least age 55 and has at least 10 Years of Benefit Service credited while a Participant in this Plan; (b) the date the Participant attains age 65; (c) the
date the Participant qualifies for benefits under an executive severance plan on account of an involuntary separation from service without cause, provided the Participant is then at least age 55; (d) the date determined by the Selection
Committee, in its discretion, provided the Participant is then at least age 62, or (e) if the Participant dies prior to Retirement, the day preceding the Participant’s date of death. Until such time as a Participant vests in a
benefit, his or her benefit under Formula B shall be deemed to be zero. 
 (b) For purposes of determining a Participant’s
“Average Compensation,” “Years of Benefit Service,” “Retirement Allowance” and “Primary Social Security Benefit” under this Plan, except as otherwise provided in this paragraph (b), such terms shall be as
defined in The Pension Plan of Arch Chemicals and take into account compensation and service (including periods of Disability, but only to the extent provided in (d), below) credited to such Participant while employed by Arch and its affiliates. In
calculating a Participant’s Average Compensation for purposes of determining X under Formula B, (i) “Average Compensation” shall also include severance and deferred amounts of regular salary and deferrals under management
incentive plans (other than the Performance Unit Plan, the EVA Bonus Bank or similar bonus bank arrangements, and other long-term incentive and long-term bonus plans of Arch); (ii) executive severance which is payable to certain Participants
under employment agreements shall be treated as if paid over the number of months of salary used to calculate the amount of such severance, even if such severance is received in a lump sum; and (iii) Average Compensation shall be calculated
without regard to the dollar limitations imposed by Code §401(a)(17). In calculating a Participant’s “Years of Benefit Service” for purposes of determining X under Formula B, service imputed as a result of treating any executive
severance paid as having been received over the number of months used to calculate such severance shall be included. 
 (c) The
annual retirement benefits payable under The Pension Plan of Arch Chemicals and the Arch Supplementary and Deferral Pension Benefit Plan which are to be used to reduce the benefit payable under Formula A and Formula B, above, shall be determined
assuming that the Participant began receiving benefits thereunder at such Plan’s Normal Retirement Date, and using the actuarial equivalent factors specified in the plans which are the subject of the offset or, if such factors are not
reasonably available, such factors as may, from time to time, be elected by the Plan Administrator. 
 (d) In the event that a
Participant becomes Disabled, the Participant shall be credited with service and compensation under this Plan for the period of Disability in the same manner as service and compensation is credited for a Disabled non-collectively bargained employee
who participates in The Pension Plan of Arch Chemicals until such time as the Participant has a Separation from Service or is no longer Disabled and returns to work. No Participant shall qualify for Disability service credit hereunder if such
Participant becomes Disabled after he or she is no longer actively employed by Arch or its affiliates.

 3.3 Normal Retirement Benefits. Retirement Benefits are payable upon a
Participant’s Normal Retirement Date, which is the date of a Participant’s Separation from Service other than on account of death, if such Separation from Service occurs on or after the Participant attains age sixty-five (65). 

3.4 Early Retirement Benefits. 
 (a) Retirement Benefits are payable upon a Participant’s Early Retirement Date, which is (i) the date the Participant incurs a Separation from Service other than on account of death at any time
after reaching his or her fifty-fifth (55th) birthday, but before his or her sixty-fifth (65th) birthday; or (ii) the Participant’s fifty-fifth birthday, if the special service crediting rule of subsection (b), below, is applicable. 
 (b) For purposes of (i) determining whether a Participant is eligible for early retirement benefits under this Section 3.4 instead
of benefits on a deferred vested basis under Section 3.5, below, and (ii) calculating the annual Retirement Allowance from The Pension Plan of Arch Chemicals which is to be used as an offset, any Participant who has completed at least
seven (7) Years of Creditable Service (as defined in the Pension Plan of Arch Chemicals, but taking into account service with Olin Corporation and its affiliates, as well as service with Arch and its affiliates) and who is at least age
fifty-two (52) on the date he or she has a Separation from Service other than (i) for cause or (ii) as a result of a voluntary termination, shall be treated as continuing as an eligible employee until the date on which the Participant
reaches age fifty-five (55). Such service shall be imputed for the sole purposes of determining whether the Participant qualifies for Early Retirement benefits, and shall not be treated as “Benefit Service” for the purpose of calculating
the amount of the benefit under this Plan. In no event will Early Retirement benefits commence under this subsection (b) until the Participant actually attains age fifty-five (55). 
 3.5 Deferred Vested Benefits. Retirement Benefits are payable upon a Participant’s Deferred Vested Retirement Date, which is the
date the Participant attains age fifty-five (55) if the Participant incurs a Separation from Service other than on account of death prior to attaining age fifty-five (55) and does not otherwise qualify for Early Retirement benefits under
Section 3.4(b), above. 
 3.6 Survivor Benefits. 
 (a) Post-Retirement Benefits. If a Participant dies after Retirement but prior to the date all payments have been made pursuant to
Section 4.1(a), hereof, the remaining payments shall be paid to the Participant’s designated beneficiary. If there is no beneficiary designation on file with the Plan Administrator, or no designated beneficiary survives the Participant,
the benefits shall be paid to the Participant’s estate (or a distributee of the Participant’s estate, as designated by the estate’s legal representative). 
 (b) Pre-Retirement Benefits. If a Participant dies prior to Retirement, a pre-retirement death benefit, equal in value to 100% of the value of the benefit that the Participant would have been
entitled to had the Participant terminated employment on the day preceding

  

 8 

 
death and survived to the earliest date on which such Participant could commence benefits hereunder, shall be payable to the Participant’s designated beneficiary (or beneficiaries). Such
benefit shall be paid as provided in Section 4.1(a) for a Retirement Benefit, provided that for this purpose (i) if the Participant is at least age fifty-five (55) on his or her date of death, the Participant’s Retirement Date
shall be deemed to be the Participant’s date of death; (ii) if the Participant is not at least age fifty-five (55) on his or her date of death, the Participant’s Retirement Date shall be deemed to be the date the Participant
would have attained age fifty-five (55) had the Participant lived; and (iii) the Participant’s Benefit Commencement Date shall be the date that would have been the Participant’s Benefit Commencement Date had the Participant
survived to his or her Retirement Date. If there is no beneficiary designation on file with the Plan Administrator, or no designated beneficiary survives the Participant, the benefits shall be paid to the Participant’s estate (or a distributee
of the Participant’s estate, as designated by the estate’s legal representative). 
 3.7 Benefits Upon a Change of
Control. 
 (a) Lump Sum Payment Upon a Change of Control. Notwithstanding any other provision of the Plan, upon a
Change in Control, each Participant covered by the Plan shall automatically be paid a single lump sum amount in cash by the Company sufficient to purchase an annuity which shall provide the Participant with the same monthly after-tax benefit (as
determined by the Plan Administrator, in consultation with the actuary for the Plan) as the Participant would have received under the Plan based on the benefits accrued to the Participant hereunder as of the date of the Change in Control. Payment
under this Section shall not in and of itself terminate the Plan, but such payment shall be taken into account in calculating benefits under the Plan which may otherwise become due the Participant thereafter. Payment shall be made within 30 days of
the Change in Control and in no event may a Participant designate (directly or indirectly) the taxable year of the payment. 
 (b) No Divestment Upon a Change of Control. If a Participant is removed from participation in the Plan after a Change of Control has occurred, in no event shall the Participant’s Years of Benefit Service accrued prior to such
removal, and the benefit accrued prior thereto, be adversely affected. 
 3.8 Non-Duplication of Benefits. In the event
that any part or all of the benefits to which a Participant is entitled under this Plan are distributed to such Participant and such Participant at any time thereafter again becomes employed by the Company or otherwise is or becomes eligible to
accrue a benefit hereunder, any benefits to which such Participant may become entitled to under this Plan shall be reduced by the actuarial equivalent of the benefits previously distributed so that in no event shall a Participant receive a
duplication of benefits under the Plan.

 Article IV. Payment of Benefits 
 4.1 Retirement Benefit Distributions. 
 (a) Form of Benefit. All Retirement Benefits shall be paid as follows: monthly life annuity benefits (as further described in Section 4.3(a), hereof), calculated as of the Participant’s
Retirement Date, and commencing as of the Participant’s Benefit Commencement Date, will be paid until the first anniversary of the Participant’s Benefit Commencement Date, at which time the lump sum present value of the remaining annuity
payments (determined in accordance with Section 4.3(b), hereof) shall be distributed in a single lump sum. 
 (b) Lump
Sum Cash-Out. Notwithstanding paragraph (a), above, the Plan Administrator may, in its sole discretion which shall be evidenced in writing no later than the date of payment, elect to pay the value of a Participant’s benefit upon a
Separation from Service in a single lump sum if the value of such benefit is not greater than the applicable dollar amount under Code §402(g)(1)(B), provided the payment represents the complete liquidation of the Participant’s interest in
the Plan (including any other deferred compensation plan that is required to be aggregated with this Plan for this purpose). 
 (c) Benefit Commencement Date. A Participant’s Benefit Commencement Date shall be the first of the month immediately following the Participant’s Retirement Date, unless a different Benefit Commencement Date has been elected
in accordance with Section 4.2, below, in which case the Participant’s Benefit Commencement Date shall be the date elected pursuant to Section 4.2. Notwithstanding the foregoing, at any time the Company is publicly traded on an
established securities market (as defined for purposes of Code §409A) and a distribution is to be made to a Specified Employee (as defined for purposes of Code §409A(a)(2)(B)(i)) on account of a Separation from Service, no distribution
shall be made to the Specified Employee on account of such Separation from Service before the date which is six months after the date of the Specified Employee’s Separation from Service, or, if earlier, the date of death of the Specified
Employee (the “Distribution Restriction Period”). To the extent that such Specified Employee would otherwise have been entitled to benefits hereunder during the Distribution Restriction Period, such amounts shall be accumulated, without
interest, and paid in a single sum, on the first day of month following the end of the Distribution Restriction Period. 
 (d)
Acceleration of or Delay in Payments. The Selection Committee, in its sole and absolute discretion, may elect to accelerate the time or form of payment of a benefit owed to the Participant hereunder, provided such acceleration is permitted
under Treas. Reg. §1.409A-3(j)(4). The Selection Committee may also, in its sole and absolute discretion, delay the time for payment of a benefit owed to the Participant hereunder, to the extent permitted under Treas. Reg. §1.409A-2(b)(7).

 4.2 Change of Benefit Distribution Elections. A Participant may change his or her Benefit Distribution Election by
filing a subsequent written election with the Plan Administrator, provided, however, that 
  

 10 

 (a) such subsequent election is approved by the Selection Committee, in its
discretion; 
 (b) such subsequent election does not take effect until at least 12 months after the date on
which the subsequent election is made; 
 (c) except with respect to the payment of a death benefit, pursuant to
such subsequent election payment is deferred for a period of not less than 5 years from the date payment would otherwise have been made or commenced; and 
 (d) with respect to any election relating to a distribution to be made (or commence) as of a specified date (or pursuant to a fixed schedule), the subsequent election is made not less than 12 months prior
to the date of the first scheduled payment. 
 Furthermore, no change of election shall permit the acceleration of the time or schedule of any
payment under the Plan, except as may be provided by regulation or other guidance issued pursuant to Code §409A(a)(3). This paragraph is intended to be (and shall be interpreted to be) consistent with Code §409A(a)(3), Code
§409A(a)(4)(C) and related guidance. 
 4.3 Actuarial Assumptions. 
 (a) Monthly Annuity Benefits. For purposes of calculating the monthly annuity benefits, if a Participant is not Married as of his or
her Benefit Commencement Date, benefits shall be calculated in the form of a single life annuity for the life of the Participant, commencing as of the Participant’s Benefit Commencement Date. If a Participant is Married as of his or her Benefit
Commencement Date, benefits shall be calculated in the form of a joint and 50% survivor annuity for the life of the Participant and the Participant’s Spouse commencing as of the Participant’s Benefit Commencement Date. The amount payable
in the form of a joint and 50% survivor annuity will be multiplied by a factor which if the Participant is at least age 62, will be one (1), and in all other cases will be an actuarially equivalent reduction factor. Notwithstanding the foregoing, if
a Participant’s Spouse is more than four years younger than the Participant, the factor in the preceding sentence shall be adjusted so that the present value of the surviving Spouse benefit is the same that it would have been if the Spouse were
only four years younger than the Participant. 
 (b) Present Value of Lump Sum. In determining the actuarial present
value of any lump sum payable hereunder the benefit shall be determined: 
 (i) as of the close of the Plan Year
in which the Participant Retires; 
 (ii) using an annuity purchase rate based upon a discount rate equal to the
lower of municipal AAA 10 year bond rate (or, if such rate cannot be reasonably determined, a comparable rate determined by the Plan Administrator in consultation with the Plan’s actuary) determined as the Participant’s Retirement Date or
15 business days prior to the date that the lump sum payment is to be made; and 
  

 11 

 (iii) assuming that the benefit commences under the Plan 
 (1) on the Participant’s 65th birthday, if the Participant terminates service (or is treated as terminating service) prior to age fifty-five (55);
and 
 (2) on the Participant’s Benefit Commencement Date, if the Participant terminates service (or is
treated as terminating service) on or after attaining age fifty-five (55). 
 (c) Other Determinations. All other
actuarial determinations under the Plan shall be made using the actuarial equivalent factors and other assumptions specified in The Pension Plan of Arch Chemicals. 
 4.4 Removal from the Plan; Non-Payment of Benefits. 
 (a) Any Participant
may be removed from the Plan by the Selection Committee at any time “for cause” as determined by the Selection Committee in its sole discretion, whether or not the Participant has begun to receive payments under the Plan, and whether or
not the Participant’s employment has been terminated. “Cause” shall include, without limitation, rendering services in any capacity to a competitor of the Company or an Employing Company or soliciting any managerial employee of
the Company or an Employing Company to leave the employ of the Arch (whether to work for a competitor of the Company or an Employing Company or otherwise), in any such case without the consent of the Selection Committee and while employed by Arch or
for a period of two years thereafter. Neither the Participant nor his or her Spouse or other beneficiary shall be entitled to receive any payments from the Plan from and after the date of the removal of the Participant and all amounts previously
paid hereunder shall be promptly repaid to the Company upon demand. Neither the Participant nor his or her Spouse or other beneficiary shall have any cause of action as a result of such removal or demand for repayment. 
 (b) The Selection Committee may notify a Participant that he or she is being suspended from the Plan as a result of job performance which
the Selection Committee, in its sole discretion, deems unsatisfactory. From and after the date of such notification, and notwithstanding the Participant’s actual Hay Points, he or she will not be deemed to have 2,000 or more Hay Points for
purposes of calculating the Participant’s Retirement Allowance. Any prior Years of Benefit Service shall not be affected by such suspension. 
 Article V. Funding 
 5.1 Unfunded Plan. This Plan shall be unfunded.

shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein. 
 2 LOAN AND TERMS OF PAYMENT 
 2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding principal amount of all Credit Extensions and accrued and unpaid interest thereon as and when due in
accordance with this Agreement. 
 2.1.1 Revolving Advances. 
 (a) Availability. Subject to the terms and conditions of this Agreement, Bank shall make Advances not exceeding the Availability
Amount. Amounts borrowed under the Revolving Line may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. 
 (b) Termination; Repayment. The Revolving Line terminates on the Revolving Line Maturity Date, when the principal amount of all
Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line shall be immediately due and payable. 
 2.1.2 Letters of Credit Sublimit. 
 (a) As part of the Revolving Line, Bank shall issue or have issued Letters
of Credit denominated in Dollars or a Foreign Currency for Borrower’s account. The aggregate Dollar Equivalent amount utilized for the issuance of Letters of Credit shall at all times reduce the amount otherwise available for Advances under the
Revolving Line. The aggregate Dollar Equivalent amount available to be used for the issuance of Letters of Credit may not exceed (a) while a Borrowing Base Period is in effect, (i) the lesser of (A) the Revolving Line or (B) the
amount available under the Borrowing Base minus (ii) the sum of all outstanding principal amounts of any Advances (including any amounts used for Cash Management Services) and the Dollar Equivalent of the face amount of any outstanding Letters
of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) and minus (iii) the aggregate amount of all FX Reserves and (b) while a Borrowing Base Period is not in effect, (i) the Revolving Line
minus (ii) the sum of all outstanding principal amounts of any Advances (including any amounts used for Cash Management Services) and the Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but
unreimbursed Letters of Credit and any Letter of Credit Reserve) and minus (iii) the aggregate amount of all FX Reserves. 
 (b) If, on the Revolving Line Maturity Date (or the effective date of any termination of this Agreement), there are any outstanding Letters of Credit, then on such date Borrower shall provide to Bank cash collateral in an amount equal to
103% (if the letter of credit is denominated in Dollars) or 110% ( if the letter of credit is denominated in a currency other than Dollars) of the Dollar Equivalent of the face amount of all such Letters of Credit plus all interest, fees, and costs
due or to become due in connection therewith (as estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to such Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in
its sole discretion and shall be subject to the

 
terms and conditions of Bank’s standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower agrees to execute any further documentation
in connection with the Letters of Credit as Bank may reasonably request. Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or
by Bank’s interpretations of any Letter of Credit issued by Bank for Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in
following Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments, or supplements thereto. 
 (c) The obligation of Borrower to immediately reimburse Bank for drawings made under Letters of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with
the terms of this Agreement, such Letters of Credit, and the Letter of Credit Application. 
 (d) Borrower may request that Bank
issue a Letter of Credit payable in a Foreign Currency. If a demand for payment is made under any such Letter of Credit, Bank shall treat such demand as an Advance to Borrower of the Dollar Equivalent of the amount thereof (plus fees and charges in
connection therewith such as wire, cable, SWIFT or similar charges). 
 (e) To guard against fluctuations in currency exchange
rates, upon the issuance of any Letter of Credit payable in a Foreign Currency, Bank shall create a reserve (the “Letter of Credit Reserve”) under the Revolving Line in an amount equal to ten percent (10%) of the face amount of
such Letter of Credit. The amount of the Letter of Credit Reserve may be adjusted by Bank from time to time to account for fluctuations in the exchange rate. The availability of funds under the Revolving Line shall be reduced by the amount of such
Letter of Credit Reserve for as long as such Letter of Credit remains outstanding. 
 2.1.3 Foreign Exchange Sublimit. As
part of the Revolving Line, Borrower may enter into foreign exchange contracts with Bank under which Borrower commits to purchase from or sell to Bank a specific amount of Foreign Currency (each, a “FX Forward Contract”) on a
specified date (the “Settlement Date”). FX Forward Contracts shall have a Settlement Date of at least one (1) FX Business Day after the contract date and shall be subject to a reserve of ten percent (10%) of each
outstanding FX Forward Contract (the “FX Reserve”). The aggregate amount of FX Forward Contracts at any one time may not exceed (a) while a Borrowing Base Period is in effect, (i) the lesser of (A) the Revolving Line
or (B) the amount available under the Borrowing Base and minus (ii) the sum of all outstanding principal amounts of any Advances (including any amounts used for Cash Management Services) and the Dollar Equivalent of the face amount of any
outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) and (b) while a Borrowing Base Period is not in effect, (i) the Revolving Line and minus (ii) the sum of all
outstanding principal amounts of any Advances (including any amounts used for Cash Management Services) and the Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any
Letter of Credit Reserve). The amount otherwise available for Credit Extensions under the Revolving Line shall be reduced by an amount equal to the aggregate amount of all FX Reserves. Any amounts needed to fully reimburse Bank for any amounts
not paid by Borrower in connection with FX Forward Contracts will be treated as Advances under the Revolving Line and will accrue interest at the interest rate applicable to Advances. 
 2.1.4 Cash Management Services Sublimit. Borrower may use the Revolving Line for Bank’s cash management services which may
include merchant services, direct deposit of payroll, business credit card, and check cashing services identified in Bank’s various cash management services agreements (collectively, the “Cash Management Services”) in an
aggregate amount not to exceed (a) while a Borrowing Base Period is in effect, (i) the lesser of (A) the Revolving Line or (B) the amount available under the Borrowing Base minus (ii) the sum of all outstanding principal
amounts of any Advances and the Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) and minus (iii) the aggregate amount of all FX
Reserves and (b) while a Borrowing Base Period is not in effect, (i) the Revolving Line minus (ii) the sum of all outstanding principal amounts of any Advances and the Dollar Equivalent of the face amount of any outstanding Letters of
Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) and minus (iii) the aggregate amount of all FX Reserves. Any amounts Bank pays on behalf of Borrower for any Cash Management Services will be treated
as Advances under the Revolving Line and will accrue interest at the interest rate applicable to Advances.

Extension. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed. 
 (g) Debit of
Accounts. Bank may debit any of Borrower’s deposit accounts, including the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes Bank when due. These debits shall not constitute a set-off.

 (a) Subject to the prior satisfaction of all
other applicable conditions to the making of an Credit Extension set forth in this Agreement, each Credit Extension shall be made upon Borrower’s irrevocable written notice delivered to Bank in the form of a Notice of Borrowing, each executed
by a Responsible Officer of Borrower or his or her designee or without instructions if the Credit Extensions are necessary to meet Obligations which have become due. Bank shall credit Credit Extensions to the Designated Deposit Account. Bank may
rely on

  

 -6- 

 
any telephone notice given by a person whom Bank reasonably believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance. Such Notice
of Borrowing must be received by Bank prior to 11:00 a.m. Eastern time (i) on the same day as the requested Funding Date, in the case of Prime Rate Credit Extensions, and (ii) at least two (2) Business Days prior to the requested
Funding Date, in the case of LIBOR Credit Extensions, specifying: 
 (1) the amount of the Credit Extension,
which, if a LIBOR Credit Extension is requested, shall be in an aggregate minimum principal amount of $500,000 or in any integral multiple of $500,000 in excess thereof; 
 (2) the requested Funding Date; 
 (3) whether the Credit Extension is to be comprised of LIBOR Credit Extensions and/or Prime Rate Credit Extensions; and 
 (4) the duration of the Interest Period applicable to any such LIBOR Credit Extensions included in such notice; provided that if the Notice of Borrowing shall fail to specify the duration of the
Interest Period for any Credit Extension comprised of LIBOR Credit Extensions, such Interest Period shall be one (1) month. 
 (b) The proceeds of all such Credit Extensions will then be made available to Borrower on the Funding Date by Bank by transfer to the Designated Deposit Account and, subsequently, by wire transfer to such other account as Borrower may
instruct in the Notice of Borrowing. No Credit Extensions shall be deemed made to Borrower, and no interest shall accrue on any such Credit Extension, until the related funds have been deposited in the Designated Deposit Account. 
 3.5 Conversion and Continuation Elections. 
 (a) So long as (i) no Event of Default or Default exists; (ii) Borrower shall not have sent any notice of termination of this Agreement; and (iii) Borrower shall have complied with such
customary procedures as Bank has established from time to time for Borrower’s requests for LIBOR Credit Extensions, Borrower may, upon irrevocable written notice to Bank: 
 (1) elect to convert on any Business Day, Prime Rate Credit Extensions in an amount equal to $500,000 or any integral
multiple of $500,000 in excess thereof into LIBOR Credit Extensions; 
 (2) elect to continue on any Payment Date
any LIBOR Credit Extensions maturing on such Payment Date (or any part thereof in an amount equal to $500,000 or any integral multiple of $500,000 in excess thereof); provided, that if the aggregate amount of LIBOR Credit Extensions shall
have been reduced, by payment, prepayment, or conversion of part thereof, to be less than $500,000, such LIBOR Credit Extensions shall automatically convert into Prime Rate Credit Extensions, and on and after such date the right of Borrower to
continue such Credit Extensions as, and convert such Credit Extensions into, LIBOR Credit Extensions shall terminate; or 
 (3) elect to convert on any Payment Date any LIBOR Credit Extensions maturing on such Payment Date (or any part thereof in an amount equal to $500,000 or any integral multiple of $500,000 in excess
thereof) into Prime Rate Credit Extensions. 
 (b) Borrower shall deliver a Notice of Conversion/Continuation to be received by
Bank prior to 11:00 a.m. Eastern time at least (i) three (3) Business Days in advance of the Conversion Date or Continuation Date, if any Credit Extensions are to be converted into or continued as LIBOR Credit Extensions; and (ii) one
(1) Business Day in advance of the Conversion Date, if any Credit Extensions are to be converted into Prime Rate Credit Extensions, in each case specifying the: 
 (1) proposed Conversion Date or Continuation Date; 
  

 -7- 

 (2) aggregate amount of the Credit Extensions to be converted or continued
which, if any Credit Extensions are to be converted into or continued as LIBOR Credit Extensions, shall be in an aggregate minimum principal amount of $500,000 or in any integral multiple of $500,000 in excess thereof; 
 (3) nature of the proposed conversion or continuation; and 
 (4) duration of the requested Interest Period. 
 (c) If upon the expiration of any Interest Period applicable to any LIBOR Credit Extensions, Borrower shall have timely failed to select a new Interest Period to be applicable to such LIBOR Credit
Extensions, Borrower shall be deemed to have elected to convert such LIBOR Credit Extensions into Prime Rate Credit Extensions. 
 (d) Any LIBOR Credit Extensions shall, at Bank’s option, convert into Prime Rate Credit Extensions in the event that (i) an Event of Default or Default shall exist, or (ii) the aggregate principal amount of the Prime Rate
Credit Extensions which have been previously converted to LIBOR Credit Extensions, or the aggregate principal amount of existing LIBOR Credit Extensions continued, as the case may be, at the beginning of an Interest Period shall at any time during
such Interest Period exceed the Availability Amount. Borrower agrees to pay Bank, upon demand by Bank (or Bank may, at its option, charge the Designated Deposit Account or any other account Borrower maintains with Bank) any amounts required to
compensate Bank for any loss (including loss of anticipated profits), cost, or expense incurred by Bank, as a result of the conversion of LIBOR Credit Extensions to Prime Rate Credit Extensions pursuant to any of the foregoing. 
 (e) Notwithstanding anything to the contrary contained herein, Bank shall not be required to purchase United States Dollar deposits in the
London interbank market or other applicable LIBOR market to fund any LIBOR Credit Extensions, but the provisions hereof shall be deemed to apply as if Bank had purchased such deposits to fund the LIBOR Credit Extensions. 
 3.6 Special Provisions Governing LIBOR Credit Extensions. Notwithstanding any other provision of this Agreement to the contrary, the
following provisions shall govern with respect to LIBOR Credit Extensions as to the matters covered: 
 (a) Determination of
Applicable Interest Rate. As soon as practicable on each Interest Rate Determination Date, Bank shall determine (which determination shall, absent manifest error in calculation, be final, conclusive and binding upon all parties) the interest
rate that shall apply to the LIBOR Credit Extensions for which an interest rate is then being determined for the applicable Interest Period and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to Borrower.

 (b) Inability to Determine Applicable Interest Rate. In the event that Bank shall have determined in good faith (which
determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any LIBOR Credit Extension, that by reason of circumstances affecting the London
interbank market adequate and fair means do not exist for ascertaining the interest rate applicable to such Credit Extension on the basis provided for in the definition of LIBOR, Bank shall on such date give notice (by facsimile or by telephone
confirmed in writing) to Borrower of such determination, whereupon (i) no Credit Extensions may be made as, or converted to, LIBOR Credit Extensions until such time as Bank notifies Borrower that the circumstances giving rise to such notice no
longer exist, and (ii) any Notice of Borrowing or Notice of Conversion/Continuation given by Borrower with respect to Credit Extensions in respect of which such determination was made shall be deemed to be rescinded by Borrower. 
 (c) Compensation for Breakage or Non-Commencement of Interest Periods. Borrower shall compensate Bank, upon written request by Bank
(which request shall set forth the manner and method of computing such compensation), for all reasonable losses, expenses and liabilities, if any (including any interest paid by Bank to lenders of funds borrowed by it to make or carry its LIBOR
Credit Extensions and any loss, expense or liability incurred by Bank in connection with the liquidation or re-employment of such funds) such that Bank may incur: (i) if for any reason (other than a default by Bank or due to any failure of Bank
to fund LIBOR Credit Extensions due to impracticability or illegality under Sections 3.7(d) and 3.7(e)) a borrowing or a conversion to or continuation of any LIBOR Credit Extension does not occur on a date specified in a Notice of Borrowing or
a Notice of Conversion/Continuation, as the case may be, or (ii) if any principal payment or any conversion of any of its LIBOR Credit Extensions occurs on a date prior to the last day of an Interest Period applicable to that Credit Extension.

  

 -8- 

 (d) Assumptions Concerning Funding of LIBOR Credit Extensions. Calculation of all
amounts payable to Bank under this Section 3.6 and under Section 3.4 shall be made as though Bank had actually funded each of its relevant LIBOR Credit Extensions through the purchase of a Eurodollar deposit bearing interest at the rate
obtained pursuant to the definition of LIBOR Rate in an amount equal to the amount of such LIBOR Credit Extension and having a maturity comparable to the relevant Interest Period; provided, however, that Bank may fund each of its LIBOR
Credit Extensions in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 3.6 and under Section 3.4. 
 (e) LIBOR Credit Extensions After Default. After the occurrence and during the continuance of an Event of Default, (i) Borrower
may not elect to have any Credit Extension be made or continued as, or converted to, a LIBOR Credit Extension after the expiration of any Interest Period then in effect for such Credit Extension and (ii) subject to the provisions of
Section 3.6(c), any Notice of Conversion/Continuation given by Borrower with respect to a requested conversion/continuation that has not yet occurred shall be deemed to be rescinded by Borrower and be deemed a request to convert or continue
Credit Extensions referred to therein as Prime Rate Credit Extensions. 
 3.7 Additional Requirements/Provisions Regarding
LIBOR Credit Extensions. 
 (a) If for any reason (including voluntary or mandatory prepayment or acceleration), Bank
receives all or part of the principal amount of a LIBOR Credit Extension prior to the last day of the Interest Period for such Credit Extension, Borrower shall immediately notify Borrower’s account officer at Bank and, on demand by Bank, pay
Bank the amount (if any) by which (i) the additional interest which would have been payable on the amount so received had it not been received until the last day of such Interest Period exceeds (ii) the interest which would have been
recoverable by Bank by placing the amount so received on deposit in the certificate of deposit markets, the offshore currency markets, or United States Treasury investment products, as the case may be, for a period starting on the date on which it
was so received and ending on the last day of such Interest Period at the interest rate determined by Bank in its reasonable discretion. Bank’s determination as to such amount shall be conclusive absent manifest error. 
 (b) Borrower shall pay Bank, upon demand by Bank, from time to time such amounts as Bank may reasonably determine to be necessary to
compensate it for any costs incurred by Bank that Bank determines are attributable to its making or maintaining of any amount receivable by Bank hereunder in respect of any Credit Extensions relating thereto (such increases in costs and reductions
in amounts receivable being herein called “Additional Costs”), in each case resulting from any Regulatory Change which: 
 (1) changes the basis of taxation of any amounts payable to Bank under this Agreement in respect of any Credit Extensions (other than changes which affect taxes measured by or imposed on the overall net
income of Bank); 
 (2) imposes or modifies any reserve, special deposit or similar requirements relating to any
Credit Extensions based upon a LIBOR Rate; or 
 (3) imposes any other material condition affecting this
Agreement (or any of such extensions of credit or liabilities). 
 Bank will notify Borrower of any event occurring after the
Effective Date which will entitle Bank to compensation pursuant to this Section 3.7 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Bank will furnish Borrower with a statement setting
forth the basis and amount of each request by Bank for compensation under this Section 3.7. Determinations and allocations by Bank for purposes of this Section 3.7 of the effect of any Regulatory Change on its costs of maintaining its
obligations to make Credit Extensions, of making or maintaining Credit Extensions, or on amounts receivable by it in respect of Credit Extensions, and of the additional amounts required to compensate Bank in respect of any Additional Costs, shall be
conclusive absent manifest error. 
  

 -9- 

 (c) If Bank shall reasonably determine that the adoption or implementation of any applicable
law, rule, regulation, or treaty regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by Bank (or its applicable lending office) with any respect or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, has or
would have the effect of reducing the rate of return on capital of Bank or any person or entity controlling Bank (a “Parent”) as a consequence of its obligations hereunder to a level below that which Bank (or its Parent) could have
achieved but for such adoption, change, or compliance (taking into consideration policies with respect to capital adequacy) by an amount deemed by Bank to be material, then from time to time, within fifteen (15) days after demand by Bank,
Borrower shall pay to Bank such additional amount or amounts as will compensate Bank for such reduction. A statement of Bank claiming compensation under this Section 3.7(c) and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive absent manifest error. 
 (d) If, at any time, Bank, in its commercially reasonable discretion,
determines that (i) the amount of LIBOR Credit Extensions for periods equal to the corresponding Interest Periods are not available to Bank in the offshore currency interbank markets, or (ii) LIBOR does not accurately reflect the cost to
Bank of lending the LIBOR Credit Extensions, then Bank shall promptly give notice thereof to Borrower. Upon the giving of such notice, Bank’s obligation to make the LIBOR Credit Extensions shall terminate; provided, however, Credit
Extensions shall not terminate if Bank and Borrower agree in writing to a different interest rate applicable to LIBOR Credit Extensions. 
 (e) If it shall become unlawful for Bank to continue to fund or maintain any LIBOR Credit Extensions, or to perform its obligations hereunder in respect of LIBOR Credit Extensions, upon demand by Bank,
Borrower shall prepay the Credit Extensions in full with accrued interest thereon and all other amounts payable by Borrower hereunder (including, without limitation, any amount payable in connection with such prepayment pursuant to
Section 3.7(a)) or Borrower shall convert such Credit Extensions to Prime Rate Credit Extensions. Notwithstanding the foregoing, to the extent a determination by Bank as described above relates to a LIBOR Credit Extension then being requested
by Borrower pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, Borrower shall have the option, subject to the provisions of Section 3.6(c), to (i) rescind such Notice of Borrowing or Notice of Conversion/Continuation
by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such rescission on the date on which Bank gives notice of its determination as described above, or (ii) modify such Notice of Borrowing or Notice of
Conversion/Continuation to obtain a Prime Rate Credit Extension or to have outstanding Credit Extensions converted into or continued as Prime Rate Credit Extensions by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such
modification on the date on which Bank gives notice of its determination as described above. 
 4 CREATION OF SECURITY
INTEREST 
 4.1 Grant of Security Interest. Borrower hereby grants Bank, to secure the payment and performance in
full of all of the Obligations, a continuing security interest in, and pledges to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof.  
 4.2 Priority of Security Interest. Borrower represents, warrants, and covenants that the security interest granted herein is and
shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under this Agreement). If Borrower shall acquire a commercial tort
claim, Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such
writing to be in form and substance reasonably satisfactory to Bank. 
 If this Agreement is terminated, Bank’s Lien in the
Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations and at such time as Bank’s obligation to make Credit Extensions has
terminated, Bank shall, at Borrower’s sole cost and expense, release its Liens in the Collateral and all rights therein shall revert to Borrower and Guarantor, as applicable. 
 4.3 Authorization to File Financing Statements. Borrower hereby authorizes Bank to file financing statements, without notice to
Borrower, with all appropriate jurisdictions to perfect or protect Bank’s interest or

  

 -10- 

 
rights hereunder, including a notice that any disposition of the Collateral, by either Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code. Such financing
statements may indicate the Collateral as “all assets of the Debtor” with the exceptions referenced on Exhibt A hereto or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Bank’s
discretion. 
 5 REPRESENTATIONS AND WARRANTIES 
 Borrower represents and warrants as follows: 
 5.1 Due Organization and Authorization; Power and Authority. Borrower and each of its Subsidiaries is duly existing and in good standing as a Registered Organization in its respective jurisdiction
of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the failure to do so could not
reasonably be expected to have a material adverse effect on Borrower’s business. In connection with this Agreement, Borrower has delivered to Bank a completed certificate substantially in the form attached hereto as Exhibit F signed by
Borrower and each Guarantor entitled “Perfection Certificate”. Borrower represents and warrants to Bank that (a) Borrower’s and covering the matters set forth therein in respect of Borrower and each Guarantor’s exact
legal name is that indicated on the Perfection Certificate and, in the case of the Borrower, on the signature page hereof; (b) Borrower and each Guarantor is an organization of the type and is organized in the jurisdiction set forth in the
Perfection Certificate; (c) the Perfection Certificate accurately sets forth Borrower’s and each Guarantor’s organizational identification number or accurately states that Borrower or such Guarantor has none; (d) the Perfection
Certificate accurately sets forth Borrower’s and each Guarantor’s place of business, or, if more than one, each chief executive office as well as Borrower’s and each Guarantor’s mailing address (if different than its chief
executive office); (e) Borrower, each Guarantor (and each of their predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its
jurisdiction; and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each Guarantor is accurate and complete. If Borrower or any Guarantor is not now a Registered Organization but later becomes one,
Borrower or such Guarantor, as the case may be, shall promptly notify Bank of such occurrence and provide Bank with Borrower’s or such Guarantor’s organizational identification number. 
 The execution, delivery and performance by Borrower and each Guarantor of the Loan Documents to which it is a party have been duly
authorized, and do not (i) conflict with any of Borrower’s or Guarantor’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene,
conflict or violate any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any of its Subsidiaries or any of their property or assets may be bound or affected,
(iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and effect) or
(v) constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could reasonably be expected to have
a material adverse effect on Borrower’s business. 
 5.2 Collateral. Borrower has good title to, has rights in, and
the power to transfer each item of Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. Borrower and each Guarantor have no Deposit Accounts other than the Deposit Accounts with
Bank and Deposit Accounts described in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice and taken such actions as are necessary to give Bank a perfected security interest therein. The
Accounts are bona fide, existing obligations of the Account Debtors. 
 The Collateral is not in the possession of any third
party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate. None of the components of the Collateral shall be maintained at locations other than as provided in the Perfection Certificate or as permitted pursuant to
Section 7.2. 
 Each of Borrower and Guarantor is the sole owner of the Intellectual Property which it owns or purports to
own except for (a) non-exclusive licenses granted to its customers in the ordinary course of business, (b) over-the-counter software that is commercially available to the public, and (c) material Intellectual Property licensed to
Borrower and noted on the Perfection Certificate. Each Patent which it owns or purports to own and which is material to Borrower’s business is valid and enforceable, and no part of the Intellectual Property which Borrower

  

 -11- 

 
owns or purports to own and which is material to Borrower’s business has been judged invalid or unenforceable, in whole or in part. To the best of Borrower’s knowledge, no claim has
been made that any part of the Intellectual Property violates the rights of any third party except to the extent such claim would not reasonably be expected to have a material adverse effect on Borrower’s business. 
 Except as noted on the Perfection Certificate, neither Borrower nor Guarantor is a party to, or is bound by, any Restricted License.

 5.3 Accounts Receivable. For any Eligible Account in any Borrowing Base Certificate, all statements made and all
unpaid balances appearing in all invoices, instruments and other documents evidencing such Eligible Accounts are true and correct in all material respects and all such invoices, instruments and other documents, and all of Borrower’s Books are
genuine and in all respects what they purport to be. If an Event of Default has occurred and is continuing, Bank may notify any Account Debtor owing Borrower money of Bank’s security interest in such funds and verify the amount of such Eligible
Account. All sales and other transactions underlying or giving rise to each Eligible Account comply in all material respects with all applicable laws and governmental rules and regulations. Borrower has no knowledge of any actual or imminent
Insolvency Proceeding of any Account Debtor whose accounts are Eligible Accounts in any Borrowing Base Certificate. To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to
all Eligible Accounts are genuine, and all such documents, instruments and agreements are legally enforceable in accordance with their terms. 
 5.4 Litigation. There are no actions or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or against Borrower or any of its Subsidiaries involving more
than, individually or in the aggregate, Five Hundred Thousand Dollars ($500,000). 
 5.5 Financial Statements; Financial
Condition. All consolidated and consolidating financial statements for Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s
consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements of Borrower submitted to Bank. 
 5.6 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of
its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature. 
 5.7 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled” by an
“investment company” under the Investment Company Act of 1940, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of
Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a
“subsidiary company” of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be
expected to have a material adverse effect on its business. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to Borrower’s knowledge, by previous Persons, in
disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given
all notices to, all Government Authorities that are necessary to continue their respective businesses as currently conducted. 
 5.8 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments. 
 5.9 Tax Returns and Payments; Pension Contributions. Borrower and its Subsidiaries have timely filed all required tax returns and reports, and Borrower and its Subsidiaries have timely paid all
foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower. Borrower may defer payment of any contested taxes, provided that Borrower (a) in good faith contests its obligation to pay the taxes by
appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any material development in, any proceedings relating to any material taxes, and (c) posts bonds or takes
any

  

 -12- 

 
other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”. Borrower
is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid all amounts necessary to fund all present pension, profit
sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event with respect to,
any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
 5.10 Use of Proceeds. Borrower shall use the proceeds of the Credit Extensions solely as working capital, for acquisitions, and to
fund its general business requirements and not for personal, family, household or agricultural purposes. 
 5.11 Full
Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, as of the date such representation, warranty, or other statement was made, taken together with all such written
certificates and written statements given to Bank, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by
Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ
materially from the projected or forecasted results). 
 5.12 Definition of “Knowledge.” For purposes of
the Loan Documents, whenever a representation or warranty is made to Borrower’s knowledge or awareness, to the “best of” Borrower’s knowledge, or with a similar qualification, knowledge or awareness means the actual knowledge,
after reasonable investigation, of the Responsible Officers. 
 6 AFFIRMATIVE COVENANTS

 6.1 Government Compliance. 
 (a) Maintain its and all its Subsidiaries’
(other than the Inactive Subsidiaries) legal existence and good standing in their respective jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a

effect on Borrower’s business. 
 (b) Obtain all of the Governmental Approvals necessary for the performance by Borrower of

Agreement or under any other agreement between Borrower and Bank; 
 (c) demand that Borrower (i) deposit cash with Bank in
an amount equal to 105% (with respect to domestic Letters of Credit) or 110% (with respect to foreign Letters of Credit) of the Dollar Equivalent of the aggregate face amount of all Letters of Credit remaining undrawn (plus all interest, fees, and
costs due or to become due in connection therewith (as estimated by Bank in its good faith business judgment)), to secure all of the Obligations relating to such Letters of Credit, as collateral security for the repayment of any future drawings
under such Letters of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all letter of credit fees scheduled to be paid or payable over the remaining term of any Letters of Credit; 
 (d) terminate any FX Forward Contracts; 
 (e) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank considers advisable, notify any Person owing Borrower money of Bank’s security
interest in such funds, and verify the amount of such account; 
 (f) make any payments and do any acts it considers necessary
or reasonable to protect the Collateral and/or its security interest in the Collateral. Borrower shall assemble the Collateral if Bank requests and make it available as Bank designates. Bank may enter premises where the Collateral is located, take
and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and
occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies; 
 (g) apply to the Obligations
any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower; 
 (h) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is hereby granted a non-exclusive, royalty-free license or other right to
use, without charge, Borrower’s labels, Patents, Copyrights, mask works, rights of use of any name, trade secrets, trade names, Trademarks, and advertising matter, or any similar property as it pertains to the Collateral, in completing

 (i) place a “hold” on any account maintained with Bank and/or deliver a notice of exclusive control, any

 (k) exercise all
rights and remedies available to Bank under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof). 
 9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable upon the occurrence and

policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and

 9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any
other Loan Document, Bank may obtain such insurance or make such payment, and all amounts so paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then highest rate applicable to the Obligations, and secured by the
Collateral. Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Bank are deemed an agreement to make similar payments in
the future or Bank’s waiver of any Event of Default. 
 9.4 Application of Payments and Proceeds Upon Default. If an
Event of Default has occurred and is continuing, Bank may apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or
otherwise, to the Obligations in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or to other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, in its
good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Bank shall have the option, exercisable at any time, of either reducing the Obligations by
the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of cash therefor. 
 9.5 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of Bank, Bank
shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman,
bailee, or other Person. Borrower bears all risk of loss, damage or destruction of the Collateral. 
 9.6 No Waiver; Remedies
Cumulative. Bank’s failure, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict
performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by the party granting the waiver and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and
remedies under this Agreement and the other Loan Documents are cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election and shall not preclude Bank
from exercising any other remedy under this Agreement or other remedy available at law or in equity, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a waiver, election, or
acquiescence. 
 9.7 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment and
nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.

 11 CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER 
 Massachusetts law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive
jurisdiction of the State and Federal courts in Massachusetts; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction to realize on the
Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Bank. Borrower expressly submits and consents in advance to the jurisdiction of the State and Federal Courts in Massachusetts in any
action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable
relief as is deemed appropriate by such court. NOTWITHSTANDING ANYTHING TO THE CONTRARY SET FORTH HEREINABOVE, BANK SHALL SPECIFICALLY HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER
JURISDICTION WHICH BANK DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANK’S RIGHTS AGAINST BORROWER OR ITS PROPERTY. 
 TO THE EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR
ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 12 GENERAL PROVISIONS 
 12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations
under it without Bank’s prior written consent (which may be granted or withheld in Bank’s discretion). Bank has the right,

  

 -23- 

 
without the consent of or notice to Borrower, to sell, transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights, and benefits
under this Agreement and the other Loan Documents. 
 12.2 Indemnification. Borrower agrees to indemnify, defend and hold
Bank and its directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Bank (each, an “Indemnified Person”) harmless against: (a) all obligations, demands, claims, and liabilities
(collectively, “Claims”) claimed or asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or expenses (including Bank Expenses) in any way suffered, incurred, or
paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions contemplated by the Loan Documents between Bank and Borrower (including reasonable attorneys’ fees and expenses), except for Claims
and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct. 
 12.3 Time of
Essence. Time is of the essence for the performance of all Obligations in this Agreement. 
 12.4 Severability of
Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision. 
 12.5 Correction of Loan Documents. Bank may fill in any blanks in the Loan Documents consistent with the agreement of the parties. 
 12.6 Amendments in Writing; Waiver; Integration. No purported amendment or modification of any Loan Document, or waiver, discharge or
termination of any obligation under any Loan Document, shall be enforceable or admissible unless, and only to the extent, expressly set forth in a writing signed by the party against which enforcement or admission is sought. Without limiting the
generality of the foregoing, no oral promise or statement, nor any action, inaction, delay, failure to require performance or course of conduct shall operate as, or evidence, an amendment, supplement or waiver or have any other effect on any Loan
Document. Any waiver granted shall be limited to the specific circumstance expressly described in it, and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give rise to, or evidence, any obligation or
commitment to grant any further waiver. The Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. 
 12.7 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and
all taken together, constitute one Agreement. 
 12.8 Survival. All covenants, representations and warranties made in
this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this
Agreement) have been paid in full and satisfied. The obligation of Borrower in Section 12.2 to indemnify Bank shall survive until the statute of limitations with respect to such claim or cause of action shall have run. 
 12.9 Confidentiality. In handling any confidential information, Bank shall exercise the same degree of care that it exercises for its
own proprietary information, but disclosure of information may be made: (a) to Bank’s Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, Bank shall use
commercially reasonable efforts to obtain such prospective transferee’s or purchaser’s agreement to the terms of this provision); (c) as required by law, regulation, subpoena, or other order; (d) to Bank’s regulators or as
otherwise required in connection with Bank’s examination or audit; (e) as Bank considers appropriate in exercising remedies under the Loan Documents; and (f) to third-party service providers of Bank so long as such service providers
have executed a confidentiality agreement with Bank with terms no less restrictive than those contained herein. Confidential information does not include information that is either: (i) in the public domain or in Bank’s possession when
disclosed to Bank, or becomes part of the public domain after disclosure to Bank (other than by the failure by Bank to maintain such information in confidence pursuant to this Section 12.9); or (ii) disclosed to Bank by a third party if
Bank does not know that the third party is prohibited from disclosing the information. 
  

 -24- 

 Bank may use confidential information for the development of databases, reporting purposes,
and market analysis so long as such confidential information is aggregated and anonymized prior to distribution unless otherwise expressly permitted by Borrower. The provisions of the immediately preceding sentence shall survive the
termination of this Agreement. 
 12.10 Attorneys’ Fees, Costs and Expenses. In any action or proceeding between
Borrower and Bank arising out of or relating to the Loan Documents, Bank shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled. 

12.11 Right of Set Off. Borrower hereby grants to Bank, a lien, security interest and right of set off as security for all
Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank
(including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any
liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL
WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. 
 12.12 Electronic Execution of Documents. The words “execution,” “signed,” “signature” and words of like
import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity and enforceability as a manually executed signature or the use of a
paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act. 
 12.13 Captions. The headings used in this Agreement are for convenience only and shall not affect the interpretation of this
Agreement.

participated in the preparation and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties caused the uncertainty to exist.

parties do not intend to create any agency, partnership, joint venture, trust, fiduciary or other relationship with duties or incidents different from those of parties to an arm’s-length contract.

remedies under or by reason of this Agreement on any persons other than the express parties to it and their respective permitted successors and assigns; (b) relieve or discharge the obligation or liability of any person not an express party to
