                                CREDIT AGREEMENT
                           DATED AS OF APRIL 16, 2007


     CREDIT AGREEMENT dated as of April 16, 2007 between HARSCO CORPORATION, a
Delaware corporation (the "BORROWER"), and THE ROYAL BANK OF SCOTLAND PLC
("RBS"). Capitalized terms not otherwise defined in this Agreement shall have
the same meanings as specified therefor in the Five-Year Credit Agreement dated
as of November 23, 2005 (as in effect on the date hereof, the "EXISTING CREDIT
AGREEMENT") among the Borrower, the lenders party thereto and JPMorgan Chase
Bank, N.A., as administrative agent for such lenders.

     SECTION 1. The Advances. (a) RBS hereby agrees, on the terms and conditions
hereinafter set forth, to make advances in U.S. dollars (each, an "ADVANCE") to
the Borrower from time to time on any Business Day during the period from the
date of this Agreement to but not including the Termination Date (as herein
defined) in an aggregate principal amount at any time outstanding not to exceed
$75,000,000 (the "FACILITY"). Within the limits of the unused portion of the
Facility in effect from time to time, the Borrower may borrow under this Section
1(a), prepay pursuant to Section 1(e) and reborrow under this Section 1(a).

     (b) The Borrower may request Advances hereunder by giving a written notice
of borrowing (a "NOTICE OF BORROWING") to RBS (A) not later than 10:00 A.M. (New
York City time) on the Business Day of such Advances for Advances bearing
interest at a rate determined by reference to the Base Rate (as defined below)
("BASE RATE ADVANCES") or (B) not later than 11:00 A.M. (New York City time) on
the third Business Day prior to such Advances for Advances bearing interest at a
rate determined by reference to the LIBO Rate ("EURODOLLAR RATE ADVANCES"),
which Notice of Borrowing shall be irrevocable and shall in each case specify
(i) whether the Advances then being requested are to be a Eurodollar Rate
Advances or Base Rate Advances, (ii) the date of such Advances (which shall be a
Business Day), (iii) the aggregate principal amount of the Advances, such amount
being at least $5,000,000 and multiples of $1,000,000 thereof and (iv) if such
Advances are to be Eurodollar Rate Advances, the Interest Period with respect
thereto. If no election as to the Type of Advances is specified, then the
requested Advances shall be Base Rate Advances. If no Interest Period with
respect to any Eurodollar Rate Advance is specified, then the Borrower shall be
deemed to have selected an Interest Period of one month's duration. Upon
fulfillment of the applicable conditions set forth in Sections 2, if applicable,
and 3, RBS will make the proceeds of such Advance available to the Borrower on
the proposed date thereof by wire transfer to the account specified by the
Borrower in the related Notice of Borrowing in immediately available funds by
12:00 noon (New York City time). All Notices of Borrowing may be delivered by
telephone if promptly confirmed in writing. For purposes of this Agreement,
"BASE RATE" means, for any day, a fluctuating rate per annum in effect from time
to time, which rate per annum shall be equal to the greater of (a) the rate of
interest announced by RBS as its base rate in effect on such day and (b) the sum
of (i) 1/2 of 1% per annum and (ii) the Federal Funds Effective Rate in effect
on such day.

     (c) The Facility shall be automatically terminated and the Borrower shall
repay to RBS the aggregate principal amount of all outstanding Advances made,
together with accrued and unpaid interest thereon, on the earliest of (i)
December 31, 2007, (ii) the date of the termination of the Facility in full
pursuant to Section 1(d) hereof, (iii) the date on which RBS shall have
terminated its commitment hereunder and declared the Advances forthwith due and
payable during the continuance of an Event of Default pursuant to Article VII of
the Existing Credit Agreement as incorporated by reference (and with respect to
an Event of Default under paragraph (g) or (h) of Article VII of the Existing
Credit Agreement, the Facility shall automatically terminate and the Advances
shall automatically become due and payable without notice) and (iv) the date on
which RBS shall have terminated its commitment hereunder and

                                        2
<PAGE>

declared the Advances forthwith due and payable upon the termination of the
Existing Credit Agreement (the "TERMINATION DATE"). Upon the issuance by the
Borrower or any of its Subsidiaries of (A) any equity security in the capital
markets or (B) any debt security in the capital markets with a maturity in
excess of one year, the Facility shall automatically permanently reduce by an
amount equal to the cash proceeds (net of the out-of-pocket fees, costs and
other expenses incurred by the Borrower or such subsidiary in connection with
such issuance, including, without limitation, all legal fees, brokerage fees,
consulting fees, accounting fees, underwriting discounts and commissions and
other customary fees, costs and expenses) actually received by the Borrower or
Subsidiary from any such issuance on the tenth Business Day after the date of
such receipt. Notwithstanding the foregoing, any proceeds received from clauses
(A) or (B )in the immediately preceding sentence will be applied in the
following order :

     First, to reduce the facility under the 364-Day Credit Agreement dated
December 23, 2005, as amended among the Borrower, The Royal Bank of Scotland
plc, and Citicorp North America, Inc.,

     Second , to reduce the Facility hereunder, and

     Third, to reduce the facility under the Credit Agreement dated the date
hereof between the Borrower and The Royal Bank of Scotland Finance(Ireland).

     (d) The Borrower may, upon at least three Business Days' notice to RBS,
terminate in whole or reduce in part the Facility.

     (e) The Borrower may, upon irrevocable notice given to RBS not later than
11:00 A.M. (New York City time) (i) on the date of the proposed prepayment, in
the case of a prepayment of Base Rate Advances or (ii) on the third Business Day
prior to the date of prepayment, in the case of a prepayment of Eurodollar Rate
Advances, in each case stating the proposed date and aggregate principal amount
of the prepayment and if such notice is given the Borrower, shall prepay the
aggregate principal amount of the Advances specified in such notice . All
notices of prepayment may be given by telephone if promptly confirmed in
writing. All prepayments under this Section 1(e) shall be made together with (i)
accrued and unpaid interest to the date of such prepayment on the principal
amount so prepaid and (ii) in the case of any such prepayment of a Eurodollar
Rate Advance on a date other than the last day of an Interest Period therefor,
any amounts owing in respect of Eurodollar Rate Advances pursuant to Section
2.15 of the Existing Credit Agreement as incorporated herein by reference.

     (f) The Borrower shall pay interest on the unpaid principal amount of each
Advance from the date of such Advance until the principal amount thereof is paid
in full on the dates for payment specified for Borrowings of the same Type under
the Existing Credit Agreement at a rate per annum equal, (i) in the case of Base
Rate Advances, at the Base Rate in effect from time to time and (ii) in the case
of Eurodollar Rate Advances, at the sum of the LIBO Rate in effect for the
applicable Interest Period plus the Applicable Margin (as defined below) from
time to time in effect. Similarly, the Borrower shall pay RBS a commitment fee
("Commitment Fee") equal to the Applicable Percentage (as hereinafter defined)
times the actual daily amount of the unused portion of the Facility. The
Commitment Fee shall accrue at all times from the date of this Agreement to the
Termination Date, and shall be due and payable quarterly in arrears on the last
Business day of each of March, June, September, and December, commencing on
June, 2007, and on the Termination Date. The Commitment Fee shall be paid in
immediately available funds and shall be non-refundable. For purposes of this
Section 2(f), the term "APPLICABLE MARGIN" shall mean 0.370% and the term
"APPLICABLE PERCENTAGE" shall mean 0.15%.

     On the Effective Date, the Borrower shall pay RBS a non-refundable upfront
fee of 0.05% of the Facility in immediately available funds ("Upfront Fee").

                                        3

     (g) The Borrower shall make each payment hereunder, irrespective of any
right of counterclaim or setoff, not later than 12:00 Noon (New York City time)
on the day when due in Dollars and in same day funds to RBS at the account of
RBS most recently specified in writing to the Borrower by RBS, with payments
received by RBS after 12:00 Noon (New York City time) on any such day being
deemed to have been received on the next succeeding Business Day. All
computations of interest determined by reference to the Base Rate and of
facility fees payable hereunder shall be made on the basis of a year of 365 or
366 days, as the case may be, and all other computations of interest, Commitment
Fees and fees payable hereunder shall be made on the basis of a year of 360
days, in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or fees
are payable.

            Party") from and against any and all claims, damages, losses,
            liabilities and expenses (including, without limitation, reasonable
            fees and expenses of counsel) incurred by or asserted or awarded
            against any Indemnified Party, in each case arising out of or in

            jurisdiction to have resulted from such Indemnified Party's gross
            negligence or willful misconduct. In the case of an investigation,
            litigation or other proceeding to which the indemnity in this
            Section 5(e) applies, such indemnity shall be effective whether or
            not such investigation, litigation or proceeding is brought by the
            Borrower, its directors, shareholders or creditors or an Indemnified
            Party or any other Person or any Indemnified Party is otherwise a
            party thereto and whether or not the transactions contemplated

                        (f) Without prejudice to the survival of any other
            agreement of the Borrower hereunder, the agreements and obligations
            of the Borrower contained in Sections 5(d) and (e) shall survive the
            payment in full of principal, interest and all other amounts payable
            hereunder and the Termination Date.

                        (g) This Agreement shall be binding upon and inure to
            the benefit of the Borrower, RBS and their respective successors and
            assigns, except that the Borrower shall not have the right to assign
            its rights hereunder or any interest herein without the prior
            written consent of RBS.

            same terms and subject to the same conditions as are set forth for
            assignments by lenders under the Existing Credit Agreement. In
            connection with any such assignment, the Borrower agrees to execute
            and deliver such documentation as RBS or any such permitted assignee
            may reasonably request to evidence such assignment and the rights
            and obligations of such assignee hereunder.

                        (i) This Agreement may be executed in separate
            counterparts by the parties hereto, each of which when so executed
            shall be deemed to be an original and all of which taken together
            shall constitute one and the same agreement. Delivery of an executed
            counterpart of a signature page to this Agreement by telecopier
            shall be effective as delivery of an originally executed counterpart
            of this Agreement.

                        (j) This Agreement shall be governed by, and construed
            in accordance with, the laws of the State of New York.
