Item 1.   Description of Registrant’s Securities to be Registered.
On January 29, 2006, the Board of Directors of USG Corporation (the “Company”) amended the Rights Agreement, dated as of March 27, 1998 (the “Rights Agreement”), by and between the Company and Harris N.A., successor to Harris Trust and Savings Bank, as rights agent. Among other things, the amendment permits the Company’s proposed equity rights offering to proceed without triggering the Rights Agreement and accelerates the expiration of the rights issued pursuant to the Rights Agreement to 11 days after the effectiveness of USG’s plan of reorganization.
The rights issued pursuant to the Rights Agreement are in all respects subject to and governed by the provisions of the Rights Agreement, as amended. Copies of the Rights Agreement are available free of charge from the Company. The foregoing description of the amendment to the Rights Agreement is qualified in its entirety by reference to the full text of the amendment, a copy of which is incorporated herein by this reference.
