Item 1.01. Entry into a Material Definitive Agreement

On March 30, 2005, United States Steel Corporation entered into an amendment of
its Amended and Restated Receivables Purchase Agreement, dated November 28, 2001
among U. S. Steel Receivables LLC, as Seller; United States Steel LLC, as
initial Servicer; the persons party thereto as CP Conduit Purchasers, Committed
Purchasers and Funding Agents; and The Bank of Nova Scotia, as Collateral Agent.
Pursuant to this amendment, the definition of "Eligible Receivable" was amended
to include receivables with payment terms of not more than 64 days as Eligible
Receivables.  Prior to this amendment that definition included otherwise
eligible receivables with payment terms of not more than 30 days and up to 15%
(of total receivables) with payment terms no greater than 60 days.  This
amendment expands the pool of Eligible Receivables, but the amount available to
United States Steel Corporation thereunder and total liquidity are not increased
because the provision of the Agreement limiting maximum sales to $500 million
was not amended.

The amended agreement is filed herewith as Exhibit 10.1.

Item 9.01. Financial Statements and Exhibits
