EXHIBIT10(aa) HARSCONON-QUALIFIED RETIREMENTSAVINGS & INVESTMENT PLAN PARTB AMENDMENT AND RESTATEMENT AS OF JANUARY 1, 2009 TABLEOF CONTENTS

1.1  

Purpose.  The Harsco Non-Qualified Retirement Savings & Investment Plan (“Plan” or “NQRSIP”) was established by Harsco Corporation (“Corporation”) to compensate participating employees for government-imposed reductions in benefits from and/or contributions to the tax-qualified Harsco Retirement Savings & Investment Plan (“RSIP”) in which they participate.

1.2  

Tax/ERISA.  The Corporation intends that the Plan shall at all times be maintained on an unfunded basis for federal income tax purposes under the Internal Revenue Code of 1986, as amended (“Code”), and administered as a “top-hat” plan exempt from the substantive requirements of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

1.3  

2009 Amendment and Restatement. The Plan was adopted as of January 1, 2004.  The Plan is hereby again amended and restated effective as of January 1, 2009 by the adoption of Part B of the Plan, as set forth herein.  Part A of the Plan, consisting of the January 1, 2004 Plan document, applies to compensation that was Deferred during calendar years ending prior to January 1, 2005 and which had become vested prior to said date, in accordance with the terms of those documents in effect from time to time prior to October 3, 2004.  The provisions of this Part B shall apply to compensation that is Deferred during calendar years beginning on or after January 1, 2005, or that was previously Deferred but not vested prior to said date.  This Part B of the Plan is intended to meet all of the requirements of Section 409A of the Code, so that Participants will be eligible to defer the receipt of, and the liability for the federal income tax with respect to, certain items of compensation from one year to a later year in accordance with the provisions of applicable law and the provisions of the Plan.  With respect to compensation that was deferred during the 2005, 2006, 2007 and 2008 calendar years, or that was Deferred prior to January 1, 2005 but became vested during the period January 1, 2005 through December 31, 2008, the terms of the Plan shall be administered in accordance with a reasonable, good faith interpretation of Code Section 409A, and such interpretation shall govern the rights of a Participant with respect to that period of time.

2.1  

Account.  The sum of the Corporation contributions and the investment returns thereon allocated to each Participant under this Plan in accordance with the provisions of Article IV.  A Participant’s Account will be divided into the following subaccounts:  (a) a “Pre-2005 Subaccount” for amounts Deferred by a Participant and vested for purposes of Code Section 409A as of December 31, 2004 (and earnings and losses thereon), and (b) a “Post-2004 Subaccount” for amounts Deferred by a Participant and/or vested for purposes of Code Section 409A after December 31, 2004 (and earnings and losses thereon).  Amounts in the Pre-2005 Subaccounts, which are intended to qualify for “grandfathered” status, shall be subject to the terms and conditions specified in Part A of the Plan as in effect on or before October 3, 2004.  The Account is not funded and is a bookkeeping record of the benefits to which a Participant is entitled under the terms of the Plan.

2.2

Retirement Savings Plan, the date of such Participant’s 65th birthday.

2.15  

Separation from Service.  The condition that exists when an employee who is a Participant in the Plan and the Corporation reasonably anticipate that no further services will be performed after a certain date or that the level of bona fide services that the employee will perform after such date (whether as an employee or an independent contractor) would permanently decrease to no more than 20% of the average level of bona fide services performed (whether as an employee or an independent contractor) over the immediately preceding 36-month period (or the full period of services to the Corporation if the employee has been providing services to the Corporation for less than 36 months).  For purposes of this Section 2.15, for periods during which an employee is on a paid bona fide leave of absence and has not otherwise experienced a Separation from Service, the employee is treated as providing bona fide services at the level equal to the level of services that the employee would have been required to perform to receive the compensation paid with respect to such leave of absence.  Periods during which an employee is on an unpaid bona fide leave of absence and has not otherwise experienced a Separation from Service are disregarded for purposes of this Section 2.15 (including for purposes of determining the applicable 36-month (or shorter) period).  For purposes of this Section 2.15, the “Corporation” shall be considered to include all members of the controlled group of corporations, trades or businesses which includes the Corporation; provided, however, that in applying Code Section 414(b), the phrase “at least 50 percent” shall be substituted for “at least 80 percent”; and in applying Code Section 414(c), the phrase “at least 50 percent” shall be used instead of the phrase “at least 80 percent.”  Separation from Service shall be determined on the basis of the modifications described in Treasury Regulation Section 1.409A-1(h)(3) (or any successor regulation)) as defined in Code Section 409A and the regulations or other guidance issued thereunder.

Eligibility to Participate in the Plan.  A select group of management or highly paid employees as designated by the Committee who are subject to government-imposed reductions in benefits from and/or contributions to the RSIP.

3.2  

Participation.  An eligible employee shall commence participation in the Plan upon the first day of his or her first payroll period following the end of the calendar quarter in which the eligible employee exceeds the limitation on Compensation taken into account under Code Section 401(a)(17).

3.3  

Vesting.  A Participant’s right to his or her Account under this Plan shall vest and become nonforfeitable only if, and to the extent that, the Participant has met the requirements for distribution due to death, Retirement, termination of employment from the Corporation or in connection with a Change In Control.

4.1  

NQRSIP Benefit.  Due to the limitations contained in Code Section 401(a)(17), a Participant is not able to receive Corporation matching contributions or Corporation discretionary contributions in the RSIP on Compensation in excess of the Code Section 401(a)(17) limit ($245,000 in 2009).  To make up for this limitation, the Corporation will contribute to this Plan an amount equal to 4% of a Participant’s Compensation in excess of the limitation contained in Code Section 401(a)(17) and make Corporation discretionary contributions to this Plan in a percentage equal to the percentage of discretionary contribution in the RSIP for the same period, if any, on the Participant’s Compensation in excess of the Code Section 401(a)(17) limit.

4.2  

Allocation of NQRSIP Benefit.  As of each Valuation Date, the Corporation will determine the amount of the contribution (Corporation’s matching contributions and discretionary contributions) due to each Participant and allocate that amount to each Participant’s Post-2004 Subaccount.  For purposes of determining the income to be allocated to the Post-2004 Subaccount, the amount will be treated as if it is allocated to the same investment funds for the Corporation’s matching contributions and discretionary contributions that the Participant selected for the tax-qualified RSIP.

4.3  

Valuation of Participant’s Post-2004 Subaccount.  As of each Valuation Date, a Participant’s Post-2004 Subaccount shall consist of the balance of the Post-2004 Subaccount as of the immediately preceding Valuation Date, plus the NQRSIP contribution credited for the quarter pursuant to Section 4.1 plus adjustments for changes in the market value of the Participant’s elected investment fund, including any dividends that would have been payable on Harsco stock, that would have been purchased by the Corporation’s matching and/or discretionary contributions and credited to the RSIP on behalf of the Participant, but for the Code or ERISA limitations.

4.4  

Crediting Investment Returns.  As of each Valuation Date, each Participant’s Post-2004 Subaccount shall be increased or decreased, as applicable, by the investment return since the immediately preceding Valuation Date.  Investment return shall be credited at the investment return rate adjusted for any contributions, to be credited for such period.  Investment return for the period shall reflect the actual investment rate earned for the deemed investment elected by the Participant under the RSIP.  Until a Participant or his or her Beneficiary receives a distribution of his or her Post-2004 Subaccount, the unpaid balance shall be adjusted for the investment return.

5.1  

Payment of Post-2004 Subaccount upon Termination, Retirement, or Change In Control.  Upon the Separation from Service (subject to paragraph 8.5) or Retirement of a Participant, or the occurrence of a Change In Control, the Corporation shall pay to the Participant or his or her Beneficiary a benefit equal to the balance of his or her Post-2004 Subaccount as of the Valuation Date coincident with or immediately prior to the Participant’s Separation from Service or Retirement, or the occurrence of a Change In Control.  This payment shall be made in a cash lump sum on the first business day of the seventh calendar month following the calendar month in which the Participant experiences a Separation from Service or Retirement, or the occurrence of a Change In Control.

5.2  

Payment of Benefits to Beneficiary.  If the Participant dies while an employee of the Corporation or prior to receiving payment under Section 5.1, his or her Post-2004 Subaccount balance shall be payable to his or her Beneficiary within ninety (90) days after the date of the Participant’s death.

6.1  

Administration of the Plan.  The Plan shall be administered by the Committee, referred to herein as the Administrator. Members of the Committee, if otherwise eligible, shall be eligible to participate in the Plan, but no such member shall be entitled to make decisions solely with respect to his or her participation.  The Administrator shall be vested with full authority to make, administer and interpret such rules and regulations as it deems necessary to administer the Plan.  Any determination, decision or action of the Administrator in connection with the construction, interpretation, administration or application of the Plan shall be final, conclusive and binding upon all Participants and any and all person claiming under or through any Participant.  The Administrator shall have the authority to:

(a)  

Employ agents to perform services on behalf of the Committee and to authorize the payment of reasonable compensation for the performance of such services.

(b)  

Delegate to the Pension Committee the authority to perform administrative duties otherwise reserved to the Administrator herein.

Amendment.  The Corporation, acting through the Board or a committee thereof, may at any time amend this Plan, in whole or in part, by an instrument in writing, executed by the Board or a committee thereof; provided, however, that no amendment shall be made which would have the effect of decreasing any Participant’s Account determined just prior to the amendment.  Written notice of any amendment or other action with respect to the Plan shall be given to each Participant.

7.2  

Termination.  The Corporation, acting through its Board or a committee thereof, may at any time terminate this Plan by an instrument in writing executed by the Board or its designee.  Upon termination of the Plan, the Committee shall take those actions necessary to administer any Accounts existing prior to the effective date of the termination; provided, however:

(a)  

no such termination shall be made which would have the effect of decreasing any Participant’s Account, as it existed as of the day before the effective date of such termination.

(b)  

the Corporation, by action of its Board or a committee thereof, may elect to accelerate all distributions at the time it elects to terminate the Plan; provided, however, that with respect to a Participant’s Post-2004 Subaccount, distributions may be accelerated only to the extent such acceleration is permitted under Treasury Regulation section 1.409A-3(j)(4)(ix).

8.1  

No Right of Employment.  Nothing in the Plan shall be deemed to grant a Participant any rights other than those specifically outlined in the Plan.  Nothing in the Plan shall be deemed to create any right of, or contract for, employment between a Participant and the Corporation.

8.2  

Withholding.  The Corporation may deduct, with respect to any payments due or benefits accrued under this Plan, any taxes required to be withheld by Federal, state or local governments.

8.3  

Non-Assignability of Benefits.  Neither the Participant nor any Beneficiary shall have the power to transfer, assign, anticipate, modify or otherwise encumber in advance any of the payments that may become due hereunder; nor shall any such payments be subject to attachment, garnishment or execution, or be transferable by operation of law in event of bankruptcy, insolvency or otherwise.

8.4  

Unfunded Status.  Any provision for payments hereunder shall be by means of bookkeeping entries on the books of the Corporation and shall not create in the Participant or his or her Beneficiary any right to, or claim against any specific assets of the Corporation, nor result in the creation of any trust or escrow account for the Participant or Beneficiary.  A Participant or Beneficiary entitled to any payment of benefits hereunder shall be a general creditor of the Corporation.

8.5  

Forfeiture on Termination For Cause.  Notwithstanding any provision to the contrary (including the acceleration of vesting and payment provisions relating to Change In Control), if any Participant is terminated for cause, all benefits hereunder shall be forfeited and the Corporation shall have no further obligation to the Participant (or his or her Beneficiary) hereunder.  For purposes of this Plan, “cause” means (i) an act or acts of personal dishonesty taken by the Participant and intended to result in substantial personal enrichment of the Participant at the expense of the Corporation, (ii) repeated violations by the Participant of the Participant’s obligations under the Participant’s employment agreement where applicable which are demonstrably willful and deliberate on the Participant’s part and which are not remedied in a reasonable period of time after receipt of written notice from the Corporation or (iii) the conviction of the Participant of a felony.
