General Motors Corp. has agreed to loan bankrupt former auto-parts supplier Delphi Corp. an additional $300 million, pending U.S. Bankruptcy Court approval, to improve the company's liquidity through this year.

The loan would bring to $950 million the amount GM has loaned the

Troy-based unit as it continues trying to exit Chapter 11 bankruptcy, according to documents filed in U.S. Bankruptcy Court.

A GM spokeswoman was not immediately available for comment this morning.

Delphi, which filed for bankruptcy protection in October 2005, said in April that it had met the conditions to emerge from Chapter 11 protection, including obtaining $6.1 billion of exit financing, but failed to emerge when its plan investors refused to take part, claiming Delphi had breached its agreement.

In May, Delphi sued its investors, including its largest shareholder, Appaloosa Management LP, seeking to force them to take part.

Delphi has been trying since then to find alternative financing to emerge from bankruptcy.
