ITEM 2.03 CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN
OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT.

On April 16, 2007, Harsco Corporation (the "Company") entered into (i) a Credit
Agreement with The Royal Bank of Scotland Finance (Ireland) ("RBS Ireland")
providing for borrowings of up to $125,000,000 and (ii) a Credit Agreement with
The Royal Bank of Scotland plc ("RBS plc"), providing for borrowings of up to
$75,000,000 (collectively, the "Credit Agreements"). Each Credit Agreement
terminates on December 31, 2007, subject to earlier termination under certain
conditions as specified in the Credit Agreement.

The Credit Agreements provide the Company with additional financial flexibility
to pursue its growth strategies. The Company also has U.S. and international
commercial paper programs and other credit facilities available as more fully
described in its Form 10-K for the fiscal year ended December 31, 2006.

The Credit Agreements incorporate by reference from the Five-Year Credit
Agreement dated November 23, 2005 (the "Existing Credit Agreement") the usual
and customary affirmative and negative covenants and events of default that
would permit the lenders to accelerate the loans if not cured within applicable
grace periods, including the failure to make timely payments, the failure to
satisfy covenants and specified events of bankruptcy and insolvency.

The foregoing descriptions of the Credit Agreements do not purport to be
complete and are qualified in their entirety by reference to the full text of
the Credit Agreements, which are attached hereto as Exhibit 10.1 and Exhibit
10.2, respectively, the full text of the Existing Credit Agreement previously
filed with the Commission on November 28, 2005 and by reference to the
description of our debt and credit agreements contained in the Company's Form
10-K for the fiscal year ended December 31, 2006. From time to time, RBS plc and
RBS Ireland may provide customary commercial and investment banking services to
the Company.
