010-8848-2744/4 INTRODUCTION Effective January 1, 1979, Harsco Corporation (the “Company”) established the Harsco Corporation Savings Plan for the benefit of eligible employees of the Company and its participating affiliates. The Harsco Corporation Savings Plan was amended from time to time following the date of its original adoption. Effective January 1, 2004, the Company established the Harsco Retirement Savings and Investment Plan (the “Plan”). The purpose of this Plan is to provide retirement income for the benefit of its Eligible Employees and their Beneficiaries. Also, effective January 1, 2004, the account balances of all salaried employees who were participants in the Harsco Corporation Savings Plan as of December 31, 2003 and are Eligible Employees hereunder were spun off and transferred into this Plan. Effective January 1, 2012, the Plan was again amended and restated in its entirety. Effective January 1, 2017, the Plan was again amended and restated in its entirety. The Plan was amended from time to time following the date of its adoption and is hereby amended and restated, effective January 1, 2019 (except as otherwise stated herein), in order to (1) incorporate previous amendments, (2) reflect the transfer of certain Altek, LLC 401(k) Profit Sharing Plan accounts into the Plan effective September 5, 2019, (3) allow for Roth deferrals effective January 1, 2020, and (4) bring the Plan into compliance with the requirements for maintenance of its tax qualified status under Sections 401(a) and 501(a) of the Internal Revenue Code (“Code”). The Company intends that this Plan, together with the Trust Agreement, shall meet all the pertinent requirements for qualification under the Internal Revenue Code of 1986, as amended, and any other requirements under the Employee Retirement Income Security Act of 1974, as amended, and the Plan and Trust Agreement shall be interpreted, wherever possible, to comply with the terms of said Code and Act and all formal regulations and rulings pertinent to the Plan and Trust Agreement issued thereunder. The Company, acting as plan sponsor, has established the Company Stock Fund for the purpose of providing an opportunity for Participants to acquire an ownership stake in the Company in order to align the interests of Participants and the Company. The Company believes that its success as an entity and the performance of the Company Stock Fund will be enhanced and facilitated in the long run by such alignment. Accordingly, the Company Stock Fund will be a permanent feature of the Plan. Except for cash or cash equivalent investments determined by the Trustee or other fiduciary to be required to facilitate Participant transactions into and out of the Company Stock Fund, the Company Stock Fund will be invested exclusively in Company Stock, without regard to the diversification of assets, the risk profile of investments in Company Stock, the amount of income provided by Company Stock, fluctuations in the fair market value of Company Stock, fluctuations in the performance of the Company's business, or the investment return of the Company Stock Fund in comparison to any other performance measure that might be appropriate for investment options other than the Company Stock Fund, in view of the purpose of the Company Stock Fund of supporting employee

• 2 - 010-8848-2744/4 ownership. Only the Company, acting as plan sponsor, will have authority to eliminate the Company Stock Fund as an investment alternative or alter the purpose of the Company Stock Fund. This Plan is intended to constitute (1) a qualified profit sharing plan, as described in Code section 401(a), which includes a qualified cash or deferred arrangement, as described in Code section 401(k); and (2) with respect to the portion of the Plan consisting of the Company Stock Fund, an employee stock ownership plan, as described in Code section 4975(e)(7), which is designed to invest exclusively in employer securities (except for liquidity needs as described in Section 16.8). In addition, this Plan is intended to meet the safe harbor requirements of Code sections 401(k)(12) and 401(m)(11). The provisions of this Plan, as amended and restated herein, shall apply only to an Eligible Employee who is credited with an Hour of Service on or after January 1, 2019, except to the extent otherwise stated in this document. The Plan provisions in effect at the time of termination of employment will apply to the Account of the terminating Participant.

The election shall be made as a whole percentage of Compensation in such manner and with such advance notice as prescribed by the Administrator. An Eligible Employee who is automatically enrolled in the Plan, as provided in Section 3.1(b), is deemed to have elected to make Pre-tax Contributions to the Plan. In no event shall an Employee’s Pre-tax Contributions and Roth Contributions under the Plan and all other plans, contracts or arrangements of all Related Companies exceed the Contribution Dollar Limit for the Employee’s taxable year beginning in the Plan Year, except that any Catch-up Contributions made by an Employee pursuant to Section 3.8 of the Plan shall not be taken into account for this purpose.

Such amounts shall be paid to the Trustee in cash and posted to each Participant’s Account(s) as soon as such amounts can reasonably be separated from the Employer’s general assets and balanced against the specific amount contributed on behalf of each Participant. In no event, however, shall such amounts be paid to the Trustee later than the 15th business day of the month following the month in which the amounts are deducted from a Participant’s Pay.

• 21 - 010-8848-2744/4 maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state. As part of a rollover contribution, the Administrator, in its discretion, may accept a loan balance which is not in default and otherwise is in compliance with the loan provisions under Article IX. The Eligible Employee shall be responsible for furnishing satisfactory evidence, in such manner as prescribed by the Administrator, that the amount is eligible for rollover treatment. A rollover contribution received directly from an Eligible Employee must be paid to the Trustee in cash within 60 days after the date received by the Eligible Employee from a qualified plan or conduit individual retirement account. Contributions described in this paragraph shall be posted to the applicable Employee’s Rollover Account as of the date received by the Trustee. If it is later determined that an amount contributed pursuant to the above paragraph did not in fact qualify as a rollover contribution under Code section 402(c) or 408(d)(3)(A)(ii), the balance credited to the Eligible Employee’s Rollover Account shall immediately be (1) segregated from all other Plan assets, (2) treated as a nonqualified trust established by and for the benefit of the Eligible Employee, and (3) distributed to the Eligible Employee. Any such nonqualifying rollover shall be deemed never to have been a part of the Plan. 4.2 Transfers From Other Qualified Plans The Administrator may instruct the Trustee to receive assets in cash or in kind (including the outstanding loan balance of any Employee loan not in default) directly from another qualified plan. The Trustee may refuse the receipt of any transfer if: (a) the Trustee finds the in-kind assets unacceptable; or (b) instructions for posting amounts to Participants’ Accounts are incomplete. The Administrator has directed the Trustee to refuse the receipt of any transfer to the Plan if: (a) any amounts are not exempted by Code section 401(a)(11)(B) from the annuity requirements of Code section 417; or (b) any amounts to be transferred include benefits protected by Code section 411(d)(6) which would not be preserved under applicable Plan provisions.

(b) Allocation Method - As of the Restatement Date, the Company Matching Contribution shall be as follows. The Company Matching Contribution (including any Forfeiture Account amounts applied as Company Matching Contributions in accordance with Section 8.4) for each period shall total 100% of the sum of the first 3% of each eligible Participant’s Pre-tax, Roth (effective January 1, 2020) and After-tax Contributions for the period and 50% of the sum of the next 2% of each eligible Participant’s Pre-tax, Roth (effective January 1, 2020) and After-tax Contributions for the period, provided that no Company Matching Contributions shall be made based upon a Participant’s Contributions in excess of 5% of his or her Compensation. The Employer may change the matching rate or the percentage of considered Pay to any other percentages, including 0%, generally by notifying eligible Participants in sufficient time to adjust their Contribution elections prior to the start of the period for which the new percentages apply. (c) Timing, Medium and Posting - The Employer shall make each period’s Company Matching Contribution in cash as soon as is feasible, and not later than the Employer’s federal tax filing date, including extensions, for deducting such Contribution.

(c) Timing, Medium and Posting - The Employer shall make each Plan Year’s Company Discretionary Contribution in cash as soon as is feasible following the end of the Plan Year, and not later than the Employer’s federal tax filing date, including extensions, for deducting such Contribution. The Trustee shall post such amount to each Participant’s Company Discretionary Contribution Account once the total Contribution received has been balanced against the specific amount to be credited to each Participant’s Company Discretionary Contribution Account. 5.3 Qualified Non-Elective Contributions The Employer reserves the right to make Qualified Non-Elective Contributions to accounts of NHCEs in order to pass the required testing described in Article XII. In any year in which the Plan does not meet the testing requirements, the Employer may either reduce accounts of HCEs to pass the test or make a corrective Qualified Non-Elective Contribution. The corrective Qualified Non-Elective Contributions shall be credited to a Participant’s Qualified Non-Elective Contribution Account and shall be immediately fully vested, without regard to a Participant’s age and service, and distributed only under the rules applicable to Pre-tax Contributions and Roth Contributions. ARTICLE VI ACCOUNTING 6.1 Individual Participant Accounting The Administrator shall maintain an individual set of Accounts for each Participant in order to reflect transactions both by type of Contribution and investment medium. Financial transactions shall be accounted for at the individual Account level by posting each transaction to the appropriate Account of each affected Participant. Participant Account values shall be maintained in shares for the Investment Funds and in dollars for Participant loan Accounts. At any point in time, the Account value shall be determined using the most recent Trade Date values provided by the Trustee. 6.2 Trade Date Accounting and Investment Cycle Participant Account values shall be determined as of each Trade Date. For any transaction to be processed as of a Trade Date, the Trustee must receive instructions for the transaction by the Trade Date. Such instructions shall apply to amounts held in the Account on that Trade Date. Financial transactions of the Investment Funds shall be posted to Participants’ Accounts as of the Trade Date, based upon the Trade Date values provided by the Trustee, and settled on the Settlement Date.

• 30 - 010-8848-2744/4 6.3 Accounting for Investment Funds Investments in each Investment Fund shall be maintained in shares. The Trustee is responsible for determining the share values of each Investment Fund as of each Trade Date. To the extent an Investment Fund is comprised of collective investment funds of the Trustee, or any other fiduciary to the Plan, the share values shall be determined in accordance with the rules governing such collective investment funds, which are incorporated herein by reference. All other share values shall be determined by the Trustee. The share value of each Investment Fund shall be based on the fair market value of its underlying assets. 6.4 Payment of Fees and Expenses Except to the extent Plan fees and expenses related to Account maintenance, transaction and Investment Fund management and maintenance, as set forth below, are paid by the Employer directly, or indirectly, through the Forfeiture Account as directed by the Administrator, such fees and expenses shall be paid as set forth below. To the extent such fees and expenses are not paid by the Employer, Participant Accounts may be reduced for such payments. The Employer may pay a lower portion of the fees and expenses allocable to the Accounts of Participants who are no longer Employees. (a) Account Maintenance - Account maintenance fees and expenses may include, but are not limited to, administrative, Trustee, government annual report preparation, audit, legal, nondiscrimination testing, and fees for any other special services. Account maintenance fees may be paid by the Employer. To the extent that such Account-maintenance fees are not paid by the Employer, Participants will be charged on a per Participant basis, provided that no fee shall reduce a Participant’s Account balance below zero. (b) Transaction - Transaction fees and expenses may include but are not limited to recurring payments, withdrawals, Investment Fund election changes, loan fees and qualification of Domestic Relations Orders. Except as provided below, transaction fees shall be charged to the Employer. (c) Investment Fund Management and Maintenance - Management and maintenance fees and expenses related to the Investment Funds shall be charged at the Investment Fund level and reflected in the net gain or loss of each Fund. The Trustee shall have the authority to pay any such fees and expenses, which remain unpaid by the Employer for 60 days, from the Trust. Notwithstanding the foregoing, the Administrator may direct that all or only certain reasonable transaction fees and expenses shall be allocated to and paid from the Accounts of the Participants and their Beneficiaries who engage in such transactions and/or the Administrator may direct that some or all of those transaction fees and expenses shall only be allocated to and paid from the Accounts of terminated Participants and their Beneficiaries to the extent permitted under Code section 411(a)(11) and the regulations and rulings issued thereunder.

• 31 - 010-8848-2744/4 6.5 Accounting for Participant Loans Participant loans shall be held in a separate Account of the Participant and accounted for in dollars as an earmarked asset of the borrowing Participant’s Account. 6.6 Error Correction The Administrator may correct any errors or omissions in the administration of the Plan by restoring any Participant’s Account balance with the amount that would be credited to the Account had no error or omission been made. To the extent legally permitted, funds necessary for any such restoration shall be taken from the Forfeiture Account or shall be provided through payment made by the Employer, or by the Trustee or other fiduciary, to the extent the error or omission is attributable to actions or inactions of any such individual or entity. 6.7 Participant Statements The Administrator shall provide Participants with statements of their Accounts not less frequently than annually. 6.8 Special Accounting During Conversion Period In the event the accounting system of the Plan is converted to another system or a new recordkeeper that has a different accounting system than that currently in use by the Plan is selected for the Plan, the Administrator and Trustee may use any reasonable accounting methods in performing their respective duties during the period of converting the accounting system of the Plan. This includes, but is not limited to, the method for allocating net investment gains or losses and the extent, if any, to which contributions received by and distributions paid from the Trust during this period share in such allocation. 6.9 Accounts for QDRO Beneficiaries A separate Account shall be established for an alternate payee entitled to any portion of a Participant’s Account under a QDRO as of the date and in accordance with the directions specified in the QDRO. In addition, a separate Account may be established during the period of time the Administrator, a court of competent jurisdiction or other appropriate person is determining whether a domestic relations order qualifies as a QDRO. Such a separate Account shall be valued and accounted for in the same manner as any Participant Account. (a) Distributions Pursuant to QDROs - If a QDRO so provides, the portion of a Participant’s Account payable to an alternate payee may be distributed, in a form as permissible under the Distribution Once Employment Ends Section, to the alternate payee at the time specified in the QDRO, regardless of whether the Participant is entitled to a distribution from the Plan at such time. (b) Participant Loans - Except to the extent required by law, an alternate payee, on whose behalf a separate Account has been established, shall not be entitled to

• 32 - 010-8848-2744/4 borrow from such Account. If a QDRO specifies that the alternate payee is entitled to any portion of the Account of a Participant who has an outstanding loan balance, all outstanding loans shall generally continue to be held in the Participant’s Account and shall not be divided between the Participant’s and alternate payee’s Accounts. (c) Investment Direction - Where a separate Account has been established on behalf of an alternate payee and has not yet been distributed, the alternate payee may direct the investment of such Account in the same manner as if he or she were a Participant. If the alternate payee does not give investment direction to the Plan, the alternate payee’s separate Account will be invested in the Plan’s default investment fund in accordance with Section 7.4. ARTICLE VII INVESTMENT FUNDS AND ELECTIONS 7.1 Investment Funds Except for Participants’ loan Accounts, the Trust shall be maintained in various Investment Funds. The Administrator shall select the Investment Funds offered to Participants and may change the number or composition of the Investment Funds, subject to the terms and conditions agreed to with the Trustee. 7.2 Investment Fund Elections Each Participant shall direct the investment of all of his or her Contribution Accounts. A Participant shall make his or her investment election in any combination of one or any number of the Investment Funds offered in accordance with the procedures established by the Administrator and Trustee. However, during a period of converting the Plan’s accounting system as provided in Section 6.8, Trust assets may be held in any investment vehicle permitted by the Plan, as directed by the Administrator, irrespective of Participant investment elections. 7.3 Responsibility for Investment Choice The Plan is intended to comply with the requirements of ERISA Section 404(c) with respect to investment elections made by Participants and Beneficiaries. Each such individual shall be solely responsible for the selection of his or her Investment Fund choices. No fiduciary with respect to the Plan is empowered to advise a Participant or Beneficiary as to the manner in which his or her Accounts are to be invested, and the fact that an Investment Fund is offered shall not be construed to be a recommendation for investment. The Employer, the Administrator, the Trustee and any other person or entity (other than each Participant or Beneficiary with respect to his or her Account) is relieved of any fiduciary duty or responsibility with respect to investment elections (including the failure to elect) made by Participants and Beneficiaries.

• 33 - 010-8848-2744/4 7.4 Default Investment Fund The Administrator shall specify an Investment Fund for the investment of (i) that portion of a Participant's Account which is not yet held in an Investment Fund and for which no valid investment election is on file; and (ii) that portion of a Participant's future contributions to the Plan which such Participant has elected to invest in the Company Stock Fund but which would cause the Participant's investment in the Company Stock Fund to exceed more than twenty percent (20%) of the value of the Participant's Account. 7.5 Timing A Participant or Beneficiary shall make his or her initial investment election upon becoming a Participant or Beneficiary and may change his or her election at any time in accordance with the procedures established by the Administrator and Trustee. Investment elections will be effective on the Trade Date which immediately follows the Trustee’s receipt of such investment elections. 7.6 Errors Relating to Participant Investment Directions If a Participant’s change in investment direction or election for redistribution of investments is inadvertently overlooked and discovery of such oversight is made within 45 days after the date the Participant receives his quarterly statement that immediately follows the oversight, the change or redistribution will be made as soon as administratively feasible and the Participant’s Accounts will be retroactively changed or redistributed and treated in the same manner as though his direction to change or redistribute had not been overlooked. If discovery of such oversight is made more than 45 days after the date the Participant receives his quarterly statement that immediately follows the oversight, the Participant’s direction will be immediately implemented but no retroactive correction will be made in the Participant’s Accounts. ARTICLE VIII VESTING & FORFEITURES 8.1 Fully Vested Contribution Accounts A Participant shall be fully vested in these Accounts at all times: After-Tax Rollover Account Altek Match Account Altek Roth Account Altek Safe Harbor Match Account Beneficiary After-tax Account Beneficiary Pretax Account Beneficiary Roth Account Brambles Profit Sharing Account Employee After-Tax Account Employee Deferral Account

• 34 - 010-8848-2744/4 Employee Roth Account ESOP Account Hammco Pre-Tax Account Hammco Roth Deferral Account Old Company Match Account Prior Company Match Account Prior ER Match Pandrol Jackson Account Prior Plan Match Account Prior Profit Sharing Account QDRO After-tax Account QDRO Pretax Account QDRO Roth Account QNEC Account Rollover Account Roth Rollover Account Sherwood Prior Match Account Unrestricted Company Match Account Notwithstanding any other provision of the Plan to the contrary, a Recmix Plan Participant's entire Account under the Plan (both before and after August 1, 2008) shall be 100% vested and nonforfeitable at all times. 8.2 Full Vesting upon Certain Events A Participant’s entire Account shall become fully vested once he or she has attained his or her Normal Retirement Date as an Employee or upon his or her leaving the Employer due to his or her Disability or death. In addition, the entire Account of a Participant who dies while performing “qualified military service” as defined in Code section 414(u)(5) shall become fully vested as of the date of the Participant's death. 8.3 Vesting Schedule A Participant shall become vested in the portion of his ER Discretionary 5 yr Account in accordance with the following schedule: Years of Vesting Service Vested Percentage Less than 5 0% 5 or more 100% A Participant shall become vested in the portion of his ER Discretionary 3 yr Account, Prior Plan Match 3 yr Account, Transfer HSP ER Discretionary 3 yr Account, Transfer HSP Match 3 yr Account, and Sherwood Prior Match 3 yr Account in accordance with the following schedule: Years of Vesting Service Vested Percentage

• 35 - 010-8848-2744/4 Less than 3 0% 3 or more 100% If this vesting schedule is changed, the vested percentage for each Participant shall not be less than his or her vested percentage determined as of the last day prior to the change, and for any Participant with at least three Years of Vesting Service when the schedule is changed, vesting shall be determined using the more favorable vesting schedule. Notwithstanding the foregoing, any dividends paid under the Company Stock Fund and credited to a Participant's ESOP Account are at all times 100% vested regardless of whether the Participant is vested in the underlying Account to which such dividends relate. 8.4 Forfeitures In the event a Participant terminates employment before becoming 100% vested in all amounts credited to his Accounts, all amounts that are not vested shall be forfeited by him and transferred to the Forfeiture Account as of the Settlement Date following the earlier of: (i) the date of distribution of his or her full vested Account, or (ii) the date he or she incurs a Break in Service. A Participant who terminates employment with no vested interest in his Account shall be deemed to have received a distribution of the entire vested balance of his Account on the date his employment terminates. The Plan shall take Pre- tax Contributions and Roth Contributions into account in determining whether a Participant has a nonforfeitable right to contributions under the Plan for purposes of forfeitures. Forfeitures from all non-vested Accounts shall be transferred to and maintained in a single Forfeiture Account. Forfeiture Account amounts shall be utilized to restore Accounts of rehired Participants and Participants who are entitled to a Contribution under the Plan, to correct errors in Plan administration pursuant to Section 15.8, to pay Plan fees and expenses, and to reduce Company Matching Contributions or Company Discretionary Contributions as directed by the Administrator. 8.5 Rehired Employees (a) Service - If a former Employee is rehired, the Period of Employment credited prior to his or her termination of employment shall be counted in determining his or her vested interest. (b) Account Restoration - If a former Employee is rehired before he or she has a Break in Service, any amount forfeited when his or her employment last terminated shall be restored to his or her Account. The restoration shall include the interest which would have been credited had such forfeiture been invested in a cash equivalent account from the date forfeited until the date the restoration amount is allocated. The amount shall come from the Forfeiture Account to the extent possible, and any additional amount needed shall be contributed by the Employer that rehired the former Employee. The vested interest in his or her restored Account shall then be equal to: (V% times (AB + D) - D) where: V% = current vested percentage

• 36 - 010-8848-2744/4 AB = current account balance D = amount previously distributed (c) In the event a Participant is reemployed after a termination of employment and either before or after a Break in Service has occurred when he had less than a one hundred percent (100%) vested interest in his Account and forfeited all or a portion of such Account, such Participant shall be given the opportunity to repay any amounts which were distributed to him in order to restore any forfeited amounts. In the event of such repayment, the Employer shall contribute such additional funds to the Plan necessary to restore any forfeiture. ARTICLE IX PARTICIPANT LOANS 9.1 Participant Loans Permitted Loans to Participants are permitted pursuant to the terms and conditions set forth in this Article. 9.2 Loan Application, Note and Security A Participant shall apply for any loan in such manner and with such advance notice as prescribed by the Administrator. All loans shall be evidenced by a promissory note, secured only by the portion of the Participant’s Account from which the loan is made, and the Plan shall have a lien on this portion of his or her Account. 9.3 Spousal Consent A Participant (other than a Participant who has an Account which includes funds from the Sherwood Selpac Corporation Profit Sharing Thrift Plan or the Track Technologies Savings Plan) is not required to obtain Spousal Consent in order to take out a loan under the Plan. 9.4 Loan Approval The Administrator, or the Trustee if otherwise authorized by the Administrator and expressly agreed to by the Trustee, is responsible for determining that a loan request conforms to the requirements described in this Article and granting such request. No new loan will be approved at any time that an existing loan of the Participant is in default. 9.5 Loan Funding Limits The loan amount must meet all of the following limits as determined as of the date the loan is processed: (a) Plan Minimum Limit - The minimum amount for any loan is $500.

• 37 - 010-8848-2744/4 (b) Plan Maximum Limit - Subject to the legal limit described in (c) below, the maximum a Participant may borrow is 100% of the fully vested portions of the following Accounts, in the following priority order: Employee Deferral Account QNEC Account Rollover Account Employee After-Tax Account After-Tax Rollover Account Prior ER Match Pandrol Jackson Account Prior Profit Sharing Account Altek Roth Account Altek Safe Harbor Match Account Altek Match Account Roth Rollover Account Employee Roth Account For the avoidance of doubt, no amounts may be borrowed from a Participant’s Hammco Roth Deferral Account or Hammco Pre-Tax Account. (c) Legal Maximum Limit - The maximum a Participant may borrow, including the outstanding balance of existing Plan loans, is 50% of his or her vested Account balance (including vested Company Matching Contributions and Company Discretionary Contributions), not to exceed $50,000. However, the $50,000 maximum is reduced by the Participant’s highest outstanding loan balance during the 12 month period ending on the day before the date as of which the loan is made. For purposes of this paragraph, the qualified plans of all Related Companies shall be treated as though they are part of this Plan to the extent it would decrease the maximum loan amount. 9.6 Maximum Number of Loans A Participant may have a maximum of one loan outstanding at any given time. Notwithstanding the foregoing, (a) if a Participant had more than one loan outstanding as of January 1, 2003 under the Harsco Corporation Savings Plan, any such loan that is transferred to this Plan effective January 1, 2004 shall continue to be outstanding, in accordance with its terms, until paid or otherwise discharged, or (b) if a Recmix Plan Participant had more than one loan outstanding as of the close of business on July 31, 2008 under the Recmix Plan, any such loan that is transferred to this Plan effective August 1, 2008 shall continue to be outstanding, in accordance with its terms, until paid or otherwise discharged. No new loan will be processed (i) while any loan (including a grandfathered loan described in the prior sentence) is outstanding: (ii) if a prior loan is in default; or (iii) within six months of the date that an outstanding loan is repaid to the Plan in full.

• 38 - 010-8848-2744/4 9.7 Source and Timing of Loan Funding A loan to a Participant shall be made solely from the assets of his or her own Accounts. The available assets shall be determined first by Account type and then by investment type within each type of Account. The hierarchy for loan funding by type of Account shall be the order listed in Subparagraph 9.5(b). Within each Account used for funding a loan, amounts shall be taken by type of investment in direct proportion to the market value of the Participant’s interest in each Investment Fund as of the Trade Date on which the loan is processed. Loans will be funded on the Settlement Date following the Trade Date as of which the loan is processed. The Trustee shall make payment to the Participant as soon thereafter as administratively feasible. 9.8 Interest Rate The interest rate charged on Participant loans shall be a fixed reasonable rate of interest, determined from time to time by the Trustee, which provides the Plan with a return commensurate with the prevailing interest rate charged by persons in the business of lending money for loans which would be made under similar circumstances. As of the Restatement Date, the interest rate charged on Participant loans shall be calculated by the Trustee as the Prime Rate plus 1% as listed in The Wall Street Journal on the first business day of each month. The interest rate determined will remain fixed throughout the duration of the loan. 9.9 Repayment Substantially level amortization shall be required of each loan with payments made at least monthly, generally through payroll deduction. Loans may be prepaid in full at any time. The Participant may choose the loan repayment period, not to exceed 5 years. However, the term may be for any period not to exceed 15 years, if the purpose of the loan is to acquire the Participant’s principal residence. 9.10 Repayment Hierarchy Loan principal repayments shall be credited to the Participant’s Accounts in the inverse of the order used to fund the loan. Loan interest shall be credited to the Participant’s Accounts in direct proportion to the principal payment. Loan payments are credited by investment type based upon the Participant’s current investment election for new Contributions. 9.11 Repayment Suspension The Administrator may agree to a suspension of loan payments for up to 12 months for a Participant who is on a Leave of Absence without pay. During the suspension period, interest shall continue to accrue on the outstanding loan balance. At the expiration of the suspension period, all outstanding loan payments and accrued interest thereon shall be due unless otherwise agreed upon by the Administrator. The Administrator may also suspend

• 39 - 010-8848-2744/4 repayment of a loan during any period of uniformed service as provided under the Uniformed Services Employment and Re-employment Rights Act of 1994. 9.12 Loan Default A loan is treated as a default if a scheduled loan payment is not made by the last day of the calendar quarter following the calendar quarter in which the loan payment was missed. A Participant shall be given written notice of the default and a demand for past due amounts to cure the default before it becomes final. In the event of default, the Administrator may direct the Trustee to report the default as a taxable distribution. As soon as a Plan withdrawal or distribution to such Participant would otherwise be permitted, the Administrator may instruct the Trustee to execute upon its security interest in the Participant’s Account by distributing the note to the Participant. 9.13 Call Feature The Administrator shall have the right to call any Participant loan once a Participant’s employment with all Related Companies has terminated or if the Plan is terminated. 9.14 Rollover of Loan Balance To the extent that an Employee makes a rollover contribution to the Plan which includes the balance of a loan, the loan will be administered in accordance with the provisions of this Article IX. ARTICLE X IN-SERVICE WITHDRAWALS 10.1 In-service Withdrawals Permitted In-service withdrawals to a Participant who is an Employee are permitted pursuant to the terms and conditions set forth in this Article and as required by law pursuant to the terms and conditions set forth in Article XI. The Plan will not permit in-service withdrawals of a Participant’s Employee Deferral Account, Employee Roth Account or a QNEC Account for purposes other than the Participant’s death, Disability, retirement, attainment of age 59½ or financial hardship. 10.2 In-service Withdrawal Application and Notice A Participant shall apply for an in-service withdrawal in such manner and with such advance notice as prescribed by the Administrator. The Participant shall be provided the notice prescribed by Code section 402(f). Code sections 401(a)(11) and 417 do not apply to in-service withdrawals under the Plan as described in this section. An in-service withdrawal may therefore commence less than 30 days but no earlier than 7 days after the aforementioned notice is provided, if:

• 40 - 010-8848-2744/4 (a) the Participant is clearly informed that he or she has the right to a period of at least 30 days after receipt of such notice to consider his or her option to elect or not elect a Direct Rollover for the portion, if any, of his or her in-service withdrawal which will constitute an Eligible Rollover Distribution; and (b) the Participant after receiving such notice, affirmatively elects a Direct Rollover for the portion, if any, of his or her in-service withdrawal which will constitute an Eligible Rollover Distribution or alternatively elects to have such portion made payable directly to him or her, there by not electing a Direct Rollover. 10.3 Spousal Consent A Participant (other than a Participant with funds in his Account from the Sherwood Selpac Corporation Profit Sharing Thrift Plan or the Track Technologies Savings Plan) is not required to obtain Spousal Consent in order to make an in-service withdrawal under the Plan. 10.4 In-Service Withdrawal Approval The Administrator, or the Trustee if otherwise authorized by the Administrator and expressly agreed to by the Trustee, is responsible for determining that an in-service withdrawal request conforms to the requirements described in this Section and granting such request. 10.5 Minimum Amount, Payment Form and Medium There is no minimum amount for any type of withdrawal. The form of payment for an in-service withdrawal shall be a single lump sum and payment shall be made in cash or in-kind at the direction of the Participant. With regard to a withdrawal representing an Eligible Rollover Distribution, a Participant may elect a Direct Rollover. 10.6 Source and Timing of In-Service Withdrawal Funding An in-service withdrawal to a Participant shall be made solely from the assets of his or her own Accounts (other than the Company Matching Account) and will be based on the Account values as of the Trade Date the in-service withdrawal is processed. The available assets shall be determined first by Account type and then by investment type within each type of Account. Within each Account used for funding an in-service withdrawal, amounts shall be taken by type of investment in direct proportion to the market value of the Participant’s interest in each Investment Fund (which excludes Participant loans) as of the Trade Date on which the in-service withdrawal is processed. In-service withdrawals will be funded on the Settlement Date following the Trade Date as of which the in-service withdrawal is processed. The Trustee shall make payment as soon thereafter as administratively feasible.

• 46 - 010-8848-2744/4 If such distribution is one to which Code sections 401(a)(11) and 417 apply, a distribution may commence less than 30 days, but more than seven days after the aforementioned notices are provided, if: (a) the Participant is clearly informed that he or she has the right to a period of at least 30 days after receipt of such notices to consider the decision as to whether to elect a distribution and, if so, to elect a particular form of distribution, and to elect or not elect a Direct Rollover for all or a portion, if any, of his or her distribution which will constitute an Eligible Rollover Distribution; (b) the Participant after receiving such notice, affirmatively elects a distribution and a Direct Rollover for all or a portion, if any, of his or her distribution which will constitute an Eligible Rollover Distribution or alternatively elects to have all or a portion made payable directly to him or her, thereby not electing a Direct Rollover for all or a portion thereof; and (c) the Participant’s election includes Spousal Consent. 11.2 Spousal Consent A Participant for whom assets were transferred to this Plan from the Sherwood Selpac Corporation Profit Sharing Thrift Plan or the Track Technologies Savings Plan and who elects a life annuity option form of payment is required to obtain Spousal Consent in order to receive a distribution under the Plan. 11.3 Payment Form and Medium A Participant whose vested Account balance is in excess of $5,000 as of the date distribution is made or commences to be made may elect to be paid in any of these forms, except that the forms described in (d) are only available to a Participant at the time he or she elects to have his or her vested Account balance paid and for whom assets were transferred to this Plan from the Sherwood Selpac Corporation Profit Sharing Thrift Plan and the forms described in (e) are only available to a Participant at the time he or she elects to have his other vested Account balance paid and for whom assets were transferred to this Plan from either the Track Technologies Savings Plan or the Hanunco Corp. 401(k) Profit Sharing Plan (and credited to the Participant's Hammco Roth Deferral Account and/or Hammco Pre-Tax Account). (a) an immediate single lump sum; or (b) a portion paid in an immediate lump sum, and the remainder paid later; or (c) periodic installments over a period not to exceed 15 years or, if less, the life expectancy of the Participant and his or her Beneficiary; or (d) a single life, a single life with a 5, 10 or 15 year term certain, a single life with installment refund, 50%, 66.67%, 75% or 100% joint life with installment refund,

Distribution shall be made in cash. Alternatively, a lump sum payment may be made in a combination of cash and whole shares of Company Stock (to the extent invested in the Company Stock Fund). With regard to the portion of a distribution representing an Eligible Rollover Distribution, a Distributee may elect a Direct Rollover for all or a portion of such amount. In the event an Eligible Rollover Distribution is made to a Distributee whose employment with the Company or any Related Company terminates as a direct result of the sale of an Employer or a business unit of an Employer and who elects to make a Direct Rollover from the Plan to a defined contribution retirement plan maintained by the purchaser of such Employer or business unit, the Plan Administrator in its sole discretion may permit the Direct Rollover of the promissory note relating to an outstanding loan maintained by the Distributee at his termination of employment. Notwithstanding any other provisions of the Plan to the contrary, if the vested value of a terminated, disabled, retired, or deceased Participant’s Account determined as of the date coincident with or immediately following his or her date of retirement, Disability, termination of employment, or death, or as of any date thereafter, does not exceed $1,000, the Administrator shall direct that the vested value of such Account shall be paid in a lump sum to the Participant (or spouse or Beneficiary, if applicable) without his or her written consent (or that of the spouse or Beneficiary, if applicable). No benefits of any other type shall then be payable to such terminated Participant or his or her spouse or Beneficiaries. Notwithstanding any other provisions of the Plan to the contrary, if the vested value of a terminated, disabled, retired or deceased Participant’s Account determined as of the date coincident with or immediately following his or her date of retirement, Disability, termination of employment, or death, or as of any date thereafter, exceeds $1,000 but does not exceed $5,000, the Administrator will permit the Participant to elect to have the vested value of such Account paid in a lump sum to the Participant (or spouse or Beneficiary, if applicable). The consent of the Participant’s spouse is not required in order to elect a lump sum payment of an amount that does not exceed $5,000. No benefits of any other type shall then be payable to such terminated Participant or his or her spouse or Beneficiaries. For the purposes of the determination under this Section 11.3 of the Plan of whether the vested value of a Participant’s Account exceeds $1,000 or $5,000, amounts credited to a Participant’s Account that are attributable to rollover contributions pursuant to Article IV shall be taken into account.

• 48 - 010-8848-2744/4 Unless the Participant or his Beneficiary elects otherwise with respect to the ESOP Component of the Plan, the balance in the Company Stock Fund must be distributed in substantially equal periodic payments (not less frequently than annually) over a period not exceeding five years. If the Participant or his Beneficiary has an accrued balance in the Company Stock Fund exceeding $500,000, the distribution may take place over a period of five years plus one year for each $100,000 or fraction thereof that his Company Stock Fund balance exceeds $500,000, as adjusted under Code section 415. 11.4 Source and Timing of Distribution Funding A distribution to a Participant shall be made solely from the assets of his or her own Accounts and will be based on the Account values as of the Trade Date the distribution is processed. The available assets shall be determined first by Account type and then by investment type within each type of Account. Within each Account used for funding a distribution, amounts shall be taken by type of investment in direct proportion to the market value of the Participant’s interest in each Investment Fund as of the Trade Date on which the distribution is processed. Distributions will be funded on the Settlement Date following the Trade Date as of which the distribution is processed. The Trustee shall make payment as soon thereafter as administratively feasible. 11.5 Deemed Distribution For purposes of Section 8.4, vested Account balances will be deemed distributed as of the Settlement Date following the date on which the Administrator has reported to the Trustee that the Participant’s non-vested Account balance shall be forfeited. 11.6 Latest Commencement Permitted In addition to any other Plan requirements and unless a Participant elects otherwise, his or her benefit payments will begin not later than 60 days after the end of the Plan Year in which he or she attains his or her Normal Retirement Date or retires, whichever is later. However, if the amount of the payment or the location of the Participant (after a reasonable search) cannot be ascertained by that deadline, payment shall be made no later than 60 days after the earliest date on which such amount or location is ascertained. 11.7 Payment Within Life Expectancy The Participant’s payment election must be consistent with the requirement of Code section 401(a)(9) that all payments are to be completed within a period not to exceed the lives or the joint and last survivor life expectancy of the Participant and his or her Beneficiary. The life expectancies of a Participant and his or her Beneficiary may not be recomputed annually.

• 49 - 010-8848-2744/4 11.8 Incidental Benefit Rule The Participant’s payment election must be consistent with the requirement that, if the Participant’s spouse is not his or her sole primary Beneficiary, the minimum annual distribution for each calendar year, beginning with the year in which he or she retires or attains age 70½ (whichever is later), shall not be less than the quotient obtained by dividing (a) the Participant’s vested Account balance as of the last Trade Date of the preceding year by (b) the applicable divisor as determined under the incidental benefit requirements of Code section 401(a)(9). Notwithstanding any other provisions of the Plan to the contrary, the Plan must begin to distribute a Participant’s entire interest in the Plan no later than his “Required Beginning Date”. The Required Beginning Date for a Participant other than a five percent (5%) owner of the Employer (as defined in Code section 416(i)(1)) shall be the April 1 of the calendar year following the later of the calendar year in which the Participant attains age 70½ or retires. The ability to receive distributions from the Plan by April 1 of the calendar year following the attainment of age 70½ is preserved for Participants who attained age 70½ prior to January 1, 2000 under the Harsco Corporation Savings Plan. The Required Beginning Date for a five percent (5%) owner is April 1 of the calendar year following the calendar year in which the Participant attains age 70½. The Plan will apply the minimum distribution requirements of Code section 401(a)(9) in accordance with the provisions in Appendix A attached hereto, notwithstanding any provision of the Plan to the contrary. 11.9 Beneficiary Designation Each Participant may complete a beneficiary designation form indicating the Beneficiary who is to receive the Participant’s remaining Plan interest at the time of his or her death. The designation may be changed at any time. However, a Participant’s spouse shall be the sole primary Beneficiary unless the designation includes Spousal Consent for another Beneficiary. A beneficiary designation form shall not become effective until it is received by the Administrator or its delegate prior to the Participant’s death. If no proper designation is in effect at the time of a Participant’s death or if the designated Beneficiary does not survive the Participant, the Beneficiary shall be, in the order listed: (a) the Participant’s surviving spouse, (b) the Participant’s children, in equal shares, per stirpes (by right of representation); or (c) the Participant’s estate. 11.10 QJSA and QPSA Information and Elections The following definitions, information and election rules shall apply to any Participant for whom assets were transferred to this Plan from the Sherwood Selpac Corporation Profit Sharing Thrift Plan or the Track Technologies Savings Plan and who elects a life annuity option:

In order to be able to roll over the distribution, the distribution otherwise must satisfy the definition of an Eligible Rollover Distribution. If a non-spouse Beneficiary receives a distribution from the Plan, the distribution is not eligible for a 60-day (non-direct) rollover. If the Participant’s named Beneficiary is a trust, the Plan may make a Direct Rollover to an IRA on behalf of the trust, provided the trust satisfies the requirements to be a designated Beneficiary within the meaning of Code section 401(a)(9)(E). A non-spouse Beneficiary may not roll over an amount that is a required minimum distribution, as determined under applicable Treasury Regulations and other Internal Revenue Service guidance. If the Participant dies before his or her required beginning date and the non-spouse Beneficiary rolls over to an IRA the maximum amount eligible for rollover, the Beneficiary may elect to use either the 5-year rule or the life expectancy rule, pursuant to Treasury Regulations Section 1.401(a)(9)-3, A-4(c), in determining the required minimum distributions from the IRA that receives the non-spouse Beneficiary’s distribution.

In addition, Contributions may include Pre-tax Contributions and Roth Contributions, but only to the extent that (1) the Employer elects to use them and (2) they are necessary to meet the ACP Test.

• 53 - 010-8848-2744/4 (d) Deferrals - Pre-tax Contributions and Roth Contributions. (e) HCE or Highly Compensated Employee - With respect to each Employer and its Related Companies, an Employee during the prior Plan Year who (in accordance with Code section 414(q)): (1) was a more than 5% Owner at any time during the current or preceding Plan Year; (2) had Compensation in excess of $80,000 (as indexed) in the prior Plan Year. The Employer may elect to limit the HCE Group to those Employees with Compensation in excess of $80,000 (as indexed) who are in the top paid group of Employees in the prior Plan Year. The top paid group consists of the top 20% of Employees in the prior Plan Year ranked on the basis of Compensation received, excluding Employees with less than 6 months of service, part-time Employees (less than 17½ hours per week or less than 6 months a year), employees under age 21 and nonresident aliens. A former Employee shall be treated as an HCE if (1) such former Employee was an HCE when he separated from service, or (2) such former Employee was an HCE in service at any time after attaining age 55. The determination of who is an HCE, including the determinations of the number and identity of Employees in the top paid group, if applicable, shall be made in accordance with Code section 414(q). (f) HCE Group and NHCE Group - With respect to each Employer and its Related Companies, the respective group of HCEs and NHCEs who are eligible to have amounts contributed on their behalf for the Plan Year, including Employees who would be eligible but for their election not to participate or to contribute, or because their Pay is greater than zero but does not exceed a stated minimum. (1) If the Related Companies maintain two or more plans which are subject to the ADP or ACP Test and are considered as one plan for purposes of Code sections 401(a)(4) or 410(b), all such plans shall be aggregated and treated as one plan for purposes of meeting the ADP and ACP Tests, provided that plans may only be aggregated if they have the same Plan Year. (2) If an HCE is covered by more than one cash or deferred arrangement maintained by the Related Companies, all such plans shall be aggregated and treated as one plan for purposes of calculating the separate percentage for the HCE which is used in the determination of the Average Percentage. (g) NHCE or Non-Highly Compensated Employee - An Employee who is not an HCE.

• 54 - 010-8848-2744/4 12.2 Special Testing of Contributions For each Plan Year, the Employer shall check the actual contribution percentages for Company Matching Contributions and After-Tax Contributions (referred to as Contributions) against the tests outlined below. Even though the Company Matching Contributions may meet the safe harbor requirements of Code sections 401(k)(12) and 401(m)(11), the Employer may voluntarily include the Company Matching Contributions with After-Tax Contributions when conducting the tests outlined below. For purposes of this testing, all Eligible Employees shall be separated into two groups: Highly Compensated Employees and Non-Highly Compensated Employees. Company Matching Contributions and After-tax Contributions to the ESOP Component of the Plan may be tested together with the Company Matching Contributions and After-tax Contributions to the Savings Plan Component of the Plan. Eligible Employees for purposes of this Section shall mean all Employees who are eligible to participate in the Plan during the Plan Year for which the tests are being made. Only one of the following two tests need be satisfied for there not to be a reduction in the percentage of Contributions for the group of Highly Compensated Employees. Test I - The ACP for the group of Highly Compensated Employees for the current Plan Year is not more than the ACP of all other Eligible Employees for the preceding Plan Year (or, if the Employer elects in accordance with the Code, the current Plan Year) multiplied by 1.25. Test II - The excess of the ACP for the group of Highly Compensated Employees for the current Plan Year over the ACP for all other Eligible Employees for the preceding Plan Year (or, if the Employer elects in accordance with the Code, the current Plan Year) is not more than 2 percentage points, and the actual contribution percentage for the group of Highly Compensated Employees for the current Plan Year is not more than the ACP for all other Eligible Employees as of the preceding Plan Year multiplied by 2.0. The contribution percentage for a specified group of Eligible Employees for a Plan Year shall be the average of the ratios (calculated separately) for each Eligible Employee in such group of the amount of Contributions actually paid to this Plan and contributions to any other plan which is aggregated with this Plan for purposes of Code section 410(b) (other than in conducting the average benefits test), on behalf of each such Eligible Employee to such Eligible Employee’s Compensation for the Plan Year. For purposes of this Section, the actual contribution ratio of a Highly Compensated Employee will be determined by treating all plans subject to Code section 401(m) under which the Highly Compensated Employee is eligible, as a single plan. All rules of application with reference to Tests I and II shall be governed by Code section 401(m) and any rules and regulations issued pursuant thereto.

• 55 - 010-8848-2744/4 The Employer may elect to use Pre-tax Contributions and/or Roth Contributions for purposes of the ACP Test so long as the applicable conditions prescribed in Treasury Regulations §1.401(m)-1(b)(4), which are incorporated herein by reference, are satisfied. The maximum amount of Contributions may be reduced, on a nondiscriminatory basis, from time to time during a Plan Year by the Administrator so as to permit the Plan to satisfy the tests described in this Section. The Administrator shall prescribe the methods and procedures by which such reductions shall be accomplished. Notwithstanding the preceding sentence, if at the end of the Plan Year, the tests are not satisfied, the Administrator shall direct the distribution to certain Highly Compensated Employees of the amounts by which Contributions actually paid on behalf of such Highly Compensated Employees exceed the maximum amount of such contributions permitted under the tests (increased by the amount of any gain and reduced by the amount of any loss allocable to such excess for the Plan Year to which such excess applies, but not for the period between the last day of the Plan Year and the date of distribution of the excess). Corrective distributions, if any, shall be made to such Highly Compensated Employees in order of the amount of Contributions beginning with the highest of such Contributions, no later than 2- 1/2 months following the end of the Plan Year. Distributions will first be made from After- tax Contributions. To the extent excess Contributions are not vested and must be distributed, such amounts shall be forfeited and used as provided in Section 8.4. 12.3 Separate Testing (a) Multiple Employers - The determination of HCEs, NHCEs, and the performance of the ACP Test and any corrective action resulting therefrom shall be made separately with regard to the Employees of each Employer (and its Related Companies) that is not a Related Company with the other Employer(s). (b) Collective Bargaining Units - The performance of the ACP Test and any corrective action resulting there from shall be applied separately to Employees who are eligible to participate in the Plan as a result of a collective bargaining agreement. In addition, separate testing may be applied, at the discretion of the Administrator and to the extent permitted under Treasury regulations, to any group of Employees for whom separate testing is permissible. ARTICLE XIII MAXIMUM CONTRIBUTION AND BENEFIT LIMITATIONS 13.1 Annual Addition Defined The sum of all amounts allocated to the Participant’s Account for a Plan Year. Amounts include contributions (except for rollovers or transfers from another qualified plan), forfeitures and, if the Participant is a Key Employee (pursuant to Article XIV) for the applicable Plan Year or any prior Plan Year, medical benefits provided pursuant to Code section 419A(d)(1). For purposes of this Section 13.1, Account also includes a Participant’s account in all other defined contribution plans currently or previously

• 56 - 010-8848-2744/4 maintained by any Related Company. The Plan Year refers to the year to which the allocation pertains, regardless of when it was allocated. The Plan Year shall be the Code section 415 limitation year. 13.2 Maximum Annual Addition The Annual Addition to a Participant’s Accounts under this Plan and his accounts under any other defined contribution plan maintained by any Related Company for any Plan Year shall not exceed the lesser of (1) 100% of his or her Taxable Income (including any Deferrals to this Plan or any other plan under Code sections 401(k), 403(b), 132(f)(4) or 125) or (2) $40,000 (as adjusted for cost of living pursuant to Code section 415(d)). For purposes of this Section 13.2, a Participant's Taxable Income shall not include any payments made to a Participant following his termination of employment with the Employer other than payments made to the Participant by the later of (a) two and one-half (2-1/2) months after the date of the Participant’s termination of employment with the Employer, or (b) the end of the limitation year that includes the date of the Participant’s termination of employment with the Employer, provided that, absent a termination of employment, such payments (A) would have been paid to the Participant if the Participant had continued in employment with the Employer, and (B) are regular compensation for services performed during the Participant’s regular working hours, compensation for services outside the Participant’s regular working hours (such as overtime or shift differential pay), commissions, bonuses, or other similar compensation. 13.3 Avoiding an Excess Annual Addition If, at any time during a Plan Year, the allocation of any additional Contributions would produce an excess Annual Addition for such year, Contributions to be made for the remainder of the Plan Year shall be limited to the amount needed for each affected Participant to receive the maximum Annual Addition. 13.4 Correcting an Excess Annual Addition If the limitation on Annual Additions is exceeded with respect to any Participant for a Plan Year, such excess Annual Addition shall be corrected in accordance with the Employee Plans Compliance Resolutions System (EPCRS), as set forth in Revenue Procedure 2019- 19 or any superseding guidance issued by the Internal Revenue Service or the Treasury Department. 13.5 Correcting a Multiple Plan Excess If a Participant, whose Account is credited with an excess Annual Addition, received allocations to more than one defined contribution plan of the Related Companies, the excess shall be corrected by reducing the Annual Addition to this Plan only after all possible reductions have been made to such other defined contribution plans.

• 57 - 010-8848-2744/4 ARTICLE XIV TOP HEAVY RULES 14.1 Top Heavy Definitions When capitalized, the following words and phrases have the following meanings when used in this Article: (a) Aggregation Group - The group consisting of the Plan and each qualified plan sponsored by the Employer (and its Related Companies) (1) in which a Key Employee is a participant or was a participant during the determination period (regardless of whether such plan has terminated), or (2) which enables this Plan or any other plan in which a Key Employee participates to meet the requirements of Code section 401(a)(4) or 410(b) (“required aggregation group”). The Employer may elect to include with the required aggregation group any other plan or plans of the Employer or Related Company not required to be included in the required aggregation group, so long as their inclusion as a part of the group would not cause such group to fail to meet the requirements of Code sections 401(a)(4) and 410(b) (“permissive aggregation group”). (b) Determination Date - The last Trade Date of the preceding Plan Year or, in the case of the Plan’s first year, the last Trade Date of the first Plan Year. (c) Key Employee - A current or former Employee (or his or her Beneficiary) who at any time during the five year period ending on the Determination Date was: (1) an officer of a Related Company whose Compensation exceeds $130,000 (as adjusted under Code section 416(i)(1)); (2) a 5% Owner; or (3) a 1% Owner whose Compensation exceeds $150,000. (d) Plan Benefit - The sum as of the Determination Date of (1) an Employee’s Account, (2) the present value of his or her other accrued benefits provided by all qualified plans within the Aggregation Group, and (3) the aggregate distributions made within the one year period ending on such date. In the case of a distribution made for a reason other than separation from service, death, or Disability, the forgoing item (3) shall be applied by substituting “five year period” for “one year period.” Plan Benefits shall exclude Rollover Contributions and plan-to-plan transfers made after December 31, 1983 which are both employee initiated and from a plan maintained by a non-related employer. (e) Top Heavy - The Plan’s status when the Plan Benefits of Key Employees account for more than 60% of the Plan Benefits of all Employees who have performed services at any time during the one-year period ending on the Determination Date. The Plan Benefits of Employees who were, but are no longer, Key Employees

• 58 - 010-8848-2744/4 (because they have not been an officer or Owner during the one year period), are excluded in the determination. (f) Non-Key Employee - Any Employee who is not a Key Employee shall be a Non-Key employee, including an Employee who was formerly a Key Employee. 14.2 Special Contributions (a) Minimum Contribution Requirement - For each Plan Year in which the Plan is Top Heavy, the Employer shall not allow any Contributions (other than a Rollover Contribution) to be made by or on behalf of any Key Employee unless the Employer makes a Contribution (other than a Pre-tax, Roth or Company Matching Contribution) on behalf of all Participants who were Eligible Employees as of the last day of the Plan Year in an amount equal to at least 3% of each such Participant’s Taxable Income. The Administrator shall remove any such Contributions (including applicable investment gain or loss) credited to a Key Employee’s Account in violation of the foregoing rule and return them to the Employer or Employee to the extent permitted by the Limited Return of Contributions paragraph of Article XVII. (b) Overriding Minimum Benefit – Notwithstanding subparagraph (a), contributions shall be permitted on behalf of Key Employees if the Employer also maintains a defined benefit plan which automatically provides a benefit which satisfies the Code section 416(c)(1) minimum benefit requirements, including the adjustment provided in Code section 416(h)(2)(A), if applicable. If this Plan is part of an aggregation group in which a Key Employee is receiving a benefit and no minimum is provided in any other plan, a minimum contribution of at least 3% of Taxable Income shall be provided to the Employees specified in the preceding paragraph of this Plan. In addition, the Employer may offset a defined benefit minimum by contributions (other than Pre-tax, Roth and Company Matching Contributions) made to this Plan. 14.3 Special Vesting If the Plan becomes Top Heavy, vesting for all Employees shall thereafter be accelerated to the extent the following vesting schedule produces a greater vested percentage for the Employee than the normal vesting schedule at any relevant time: Years of Vesting Service Vested Percentage Less than 3 0% 3 or more 100%

• 62 - 010-8848-2744/4 expenses not paid directly by the Employer. Plan benefits will be drawn solely from the Trust and paid by the Trustee as directed by the Administrator. Notwithstanding, the Administrator may appoint, with the approval of the Trustee, another trustee to hold and administer Plan assets which do not meet the requirements of Section 16.2. 16.2 Investment Funds The Administrator is hereby granted authority to direct the Trustee to invest Trust assets in one or more Investment Funds. The Trustee may establish reasonable limits on the number of Investment Funds as well as the acceptable assets for any such Investment Fund. Each of the Investment Funds may be comprised of any of the following: (a) shares of a registered investment company, whether or not the Trustee or any of its affiliates is an advisor to, or other service provider to, such company; (b) collective investment funds maintained by the Trustee, or any other fiduciary to the Plan, which are available for investment by trusts which are qualified under Code sections 401(a) and 501(a); (c) individual equity and fixed income securities which are readily tradeable on the open market; (d) guaranteed investment contracts issued by a bank or insurance company; (e) interest bearing deposits of the Trustee; and (f) Company Stock.

• 63 - 010-8848-2744/4 16.5 Administrator Has Right to Vote Registered Investment Company Shares The Administrator shall be entitled to vote proxies or exercise any shareholder rights relating to shares held on behalf of the Plan in a registered investment company. Notwithstanding, the authority to vote proxies and exercise shareholder rights related to such shares held in a Custom Fund is determined in accordance with Sections 16.6 and 16.9 hereof. 16.6 Custom Fund Investment Management The Administrator may designate, with the consent of the Trustee, an investment manager for any Investment Fund established by the Trustee solely for Participants of this Plan (a Custom Fund). The investment manager may be the Administrator, Trustee or an investment manager pursuant to ERISA section 3(38).

The Fund may be as large as necessary to comply with Participants' and Beneficiaries' investment elections, as well the investment of Participants' and Beneficiaries ' Company Matching Accounts. The Company Stock Fund is credited with Company Stock either contributed directly by the Company or purchased with Company contributions. The Company Stock Fund is also credited with Company Stock purchased pursuant to investment elections by Plan Participants. Effective as of July 1, 2014, no Participant shall be permitted to invest more than twenty percent (20%) of his or her Account in the Company Stock Fund. To the extent that, as of July 1, 2014, more than twenty percent (20%) of a Participant's Account is invested in the Company Stock Fund, such Participant shall not be required to divest his or her investment in the Company Stock Fund to twenty percent (20%); however, no future contributions made by or on behalf of such a Participant shall be invested in the Company Stock Fund until such time as the Participant's total investment in the Company Stock Fund is less than twenty percent (20%). With respect to Participants described in the preceding sentence or in the event that a Participant's investment election with respect to future contributions to the Plan would cause the Participant to exceed the twenty percent (20%) limitation described above, the Participant's future contributions (or such portion of the future contributions that would cause the Participant's Account to exceed the twenty percent (20%) limitation) shall be invested in the Investment Fund described in Section 7.4. The limitation set forth in this paragraph shall not apply to prevent a Participant from reinvesting dividends paid on Company Stock in the Company Stock Fund pursuant to Section 16.11. 16.9 Participants Have Right to Vote and Tender Company Stock Each Participant or Beneficiary shall be entitled to instruct the Trustee as to the voting or tendering of any full or partial shares of Company Stock held on his or her behalf in the Company Stock Fund. Prior to such voting or tendering of Company Stock, each Participant or Beneficiary shall receive a copy of the proxy solicitation or other material relating to such vote or tender decision and a blank form for the Participant or Beneficiary to complete which confidentially instructs the Trustee to vote or tender such shares in the manner indicated by the Participant or Beneficiary. Upon receipt of such instructions, the

• 65 - 010-8848-2744/4 Trustee shall act with respect to such shares as instructed. With respect to shares for which no instructions were received, the Trustee shall vote the shares in the same proportion as the shares actually voted by the Participants and Beneficiaries. With respect to a tender offer, a failure by a Participant or Beneficiary to instruct the Trustee shall be regarded as the Participant’s or Beneficiary’s instruction not to tender his or her shares. 16.10 Registration and-Disclosure for Company Stock The Administrator shall be responsible for determining the applicability of (and, if applicable, complying with) the requirements of the Securities Act of 1933, as amended, and any other applicable blue sky law. The Administrator shall also specify what restrictive legend or transfer restriction, if any, is required to be set forth on the certificates for the securities and the procedure to be followed by the Trustee to effectuate a resale of such securities. 16.11 Reinvestment of Dividends Paid on Company Stock in the Company Stock Fund Any dividends paid on Company Stock in the Company Stock Fund may, at the election of the Participant or Beneficiary, be reinvested in Company Stock. The Participant or Beneficiary will have option (a), (b) or (c) as outlined below with respect to such dividend: (a) have the dividend paid in cash to the Participant or Beneficiary; or (b) have the dividend paid to the Plan and distributed in cash to the Participant or Beneficiary within 90 days after the close of the Plan Year of the dividend payment; or (c) have the dividend paid to the Plan and reinvested in Company Stock. If a Participant or Beneficiary makes no election, he or she will deemed to have elected to have the dividend paid to the Plan and reinvested in Company Stock under option (c) above. Any dividends paid to the Plan will be maintained in the ESOP Investment Fund pending the purchase of Company Stock for the Company Stock Fund. ARTICLE XVII RIGHTS, PROTECTION, CONSTRUCTION, AND JURISDICTION 17.1 Plan Does Not Affect Employment Rights The Plan does not provide any employment rights to any Employee. The Related Companies expressly reserve the right to discharge an Employee at any time, with or without cause, and without regard to the effect such discharge would have upon the Employee’s interest in the Plan. 17.2 Limited Return of Contributions Except as provided in this paragraph, (1) Plan assets shall not revert to the Employer nor be diverted for any purpose other than the exclusive benefit of Participants or their

• 66 - 010-8848-2744/4 Beneficiaries; and (2) a Participant’s vested interest shall not be subject to divestment. As provided in ERISA section 403(c)(2), the actual amount of a Contribution made by the Employer (or the current value of the Contribution if a net loss has occurred) may revert to the Employer if: (a) such Contribution is made by reason of a mistake of fact; (b) initial qualification of the Plan under Code section 401(a) is not received and a request for such qualification is made within the time prescribed under Code section 401(b) (the existence of and Contributions under the Plan are hereby conditioned upon such qualification); or (c) such Contribution is not deductible under Code section 404 (such Contributions are hereby conditioned upon such deductibility) in the taxable year of the Employer for which the Contribution is made. The reversion to the Employer must be made (if at all) within one year of the mistaken payment of the Contribution, the date of denial of initial qualification, or the date of disallowance of deduction, as the case may be. A Participant shall have no rights under the Plan with respect to any such reversion. 17.3 Assignment and Alienation As provided by Code section 401(a)(13) and to the extent not otherwise required by law, no benefit provided by the Plan may be anticipated, assigned or alienated, except: (a) to create, assign or recognize a right to any benefit with respect to a Participant pursuant to a QDRO; (b) to use a Participant’s vested Account balance as security for a loan from the Plan which is permitted pursuant to Code section 4975; or (c) to satisfy liabilities a Participant owes to the Plan due to (i) the Participant being convicted of committing a crime involving the plan; (ii) a civil judgment or consent order or decree being entered by a court in an action brought in connection with a violation of ERISA’s fiduciary duty rules; or (iii) a settlement agreement between the Secretary of Labor or the PBGC and the Participant in connection with a violation of ERISA’s fiduciary rules. The court order establishing liability must require that the Participant’s Account be applied to satisfy the liability. 17.4 Claims Procedure Other Than Disability (a) Right to Make Claim – A claimant who disagrees with the Administrator’s determination of his or her right to Plan benefits must submit a written claim and exhaust this claim procedure before legal recourse of any type is sought. The claim must include the important issues the claimant believes support the claim. The Administrator, pursuant to the authority provided in this Plan, shall either approve or deny the claim.

Section A2 Time and Manner of Distribution A2.1 Required Beginning Date. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s required beginning date. A2.2 Death of Participant Before Distributions Begin. If the Participant dies before distributions begin, the Participant’s entire interest will be distributed, or begin to be distributed, no later than as follows: (a) If the Participant’s surviving spouse is the Participant’s sole Beneficiary, then distributions to the surviving spouse will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70½, if later. (b) If the Participant’s surviving spouse is not the Participant’s sole Designated Beneficiary, then distributions to the Designated Beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died. (c) If there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, the Participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. (d) If the Participant’s surviving Spouse is the Participant’s sole Designated Beneficiary and the surviving Spouse dies after the Participant but before distributions to the surviving spouse begin, this Section A2.2, other than A2.2(a), will apply as if the surviving spouse were the Participant.

• 75 - 010-8848-2744/4 For purposes of this Section A2.2 and Section A5, distributions are considered to begin on the Participant’s required beginning date (or, if Section A2.2(d) applies, the date distributions are required to begin to the surviving spouse under A2.2(a)). If annuity payments irrevocably commence to the Participant before the Participant’s required beginning date (or to the surviving spouse before the date distributions are required to begin to the surviving spouse under A2.2(a)), the date distributions are considered to begin is the date distributions actually commence. A2.3 Form of Distribution. Unless the Participant’s interest is distributed in the form of a single lump sum on or before the required beginning date, as of the first distribution calendar year distributions will be made in accordance with Sections A3, A4 and A5 of this Appendix A. Section A3 Required Minimum Distributions During Participant’s Lifetime A3.1 Amount of Required Minimum Distribution for Each Distribution Calendar Year. During the Participant’s lifetime, the minimum amount that will be distributed for each distribution calendar year is the lesser of: (a) the quotient obtained by dividing the Participant’s Individual Account by the distribution period in the Uniform Lifetime Table in section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year; or (b) if the Participant’s sole Designated Beneficiary for the distribution calendar year is the Participant’s spouse, the quotient obtained by dividing the Participant’s Individual Account by the number in the Joint and Last Survivor Table in section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s and spouse’s attained ages as of the Participant’s and spouse’s birthdays in the distribution calendar year. A3.2 Lifetime Required Minimum Distributions Continue Through Year of Participant’s Death. Required minimum distributions will be determined under this Section A3 beginning with the first distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of death. Section A4 Required Minimum Distributions After Participant’s Death A4.1 Death on or after Date Distributions Begin. (a) Participant Survived by Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Individual Account by the longer of the remaining life expectancy of the Participant or the remaining life expectancy of the Participant’s Designated Beneficiary, determined as follows:

• 76 - 010-8848-2744/4 (i) The Participant’s remaining life expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year. (ii) If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, the remaining life expectancy of the surviving spouse is calculated for each distribution calendar year after the year of the Participant’s death using the surviving spouse’s age as of the spouse’s birthday in that year. For distribution calendar years after the year of the surviving spouse’s death, the remaining life expectancy of the surviving spouse is calculated using the age of the surviving spouse as of the spouse’s birthday in the calendar year of the spouse’s death, reduced by one for each subsequent calendar year. (iii) If the Participant’s surviving spouse is not the Participant’s sole Designated Beneficiary, the Designated Beneficiary’s remaining life expectancy is calculated using the age of the Beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year. (b) No Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is no Designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Individual Account by the Participant’s remaining life expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year. A4.2 Death Before Date Distributions Begin. (a) Participant Survived by Designated Beneficiary. If the Participant dies before the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Individual Account by the remaining life expectancy of the Participant’s Designated Beneficiary, determined as provided in Section A4.1. (b) No Designated Beneficiary. If the Participant dies before the date distributions begin and there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire interest will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. (c) Death of Surviving Spouse Before Distributions to Surviving Spouse are Required to Begin. If the Participant dies before the date distributions begin, the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, and the surviving spouse dies before distributions are required to begin to the surviving spouse under Section A2.2(a), this Section A4.2 will apply as if the surviving spouse were the Participant.
