The gargantuan legal bill for the 2010 catastrophic oil spill in the Gulf of Mexico is coming due for BP as a federal trial opens Monday, Feb. 27, 2012 to determine the company's liability for the blowout of its Macondo well. On the cusp of trial, phalanxes of lawyers, company officials and state officials spent the final hours in high-stakes settlement talks that law experts believed could still yield a deal right before the courtroom doors open Monday morning.

BP has agreed to pay around $4.5 billion and plead guilty to 11 felony charges for the 2010 oil spill that devastated the Gulf coast, Bloomberg reports.

BP will also plead guilty to obstruction for lying to Congress about the amount of oil that had actually been spilt into the Gulf of Mexico, AP reports. The fine will be paid for over six years.

Attorney General Eric Holder is expected to hold a press conference on Thursday in New Orleans to announce an agreement between the Department of Justice and BP over the 2010 oil spill that devastated the Gulf coast, The Wall Street Journal reported.

BP says publicly that discussions have advanced, but has not confirmed that an official deal has been made.

"No final agreements have yet been reached and any resolutions, if agreed, would be subject to federal court approvals in the United States," BP said in a statement, according to The Journal.

The deal would reportedly cover criminal charges and claims by the Securities and Exchange Commission, but would not cover federal civil claims and some other actions the company may face.

The Deepwater Horizon explosion in the Gulf of Mexico led to the worst oil spill in U.S. history, killing 11 people and devastating wildlife. Two BP employees will face manslaughter charges over those deaths, AP reports.
