SCOTT DEPOT, W. VA.

Mine operator International Coal Group said Thursday it is making some changes to a previously announced cash tender offer for some of its outstanding debt.

The offer is for any and all of the $139.5 million principal amount of its outstanding 9 percent convertible senior notes due 2012.

The amendments change the pricing date from April 5 to April 1 and eliminate various tender and withdrawal procedures and information deliveries that were related to a pricing date of April 5.

They also clarify how the daily volume-weighted average price of the company's common stock is calculated and report the closing of the company's concurrent offerings of convertible notes and common stock, which satisfied the refinancing condition to the tender offer.

The expiration time of the tender offer remains April 5.
