HOUSTON (CNNMoney.com) - Enron founder Kenneth Lay and former chief executive Jeffrey Skilling face another day of waiting as jurors in the biggest corporate trial in recent history begin their sixth day of deliberations Thursday.

The two men remain absent from the courthouse while their attorneys Daniel Petrocelli and Michael Ramsey wait in the courtroom for word from Judge Sim Lake.

The jury of eight women and four men made two requests of the court Wednesday - asking for copies of the exhibit list and specific trial testimony transcripts, although they did not specify which transcripts they wanted.

Otherwise, the jurors have given little indication of their progress since they began deliberating last Wednesday afternoon.

After 16 weeks and 56 days of testimony and documents, the jurors have a large range of factors to consider, including the testimony of over 50 witnesses including both defendants and persuasive closing arguments by defense attorneys for both Skilling and Lay.

In a possible sign that the jury is still not close to reaching a decision, Judge Lake received a note late Tuesday afternoon indicating that the jury decided that they do not plan to deliberate Friday or Monday, which is the Memorial Day holiday.

Skilling faces 28 counts of conspiracy, fraud and insider trading. Lay faces six counts of conspiracy and fraud, in addition to the separate four charges of bank fraud. Experts say the two men face about 20 to 30 years in prison if convicted.

Not only are Lay and Skilling waiting on the judgment of the jury in the criminal trial, Lay also must wait for Judge Lake to render a verdict in the bank fraud trial that concluded Tuesday afternoon.

In that case, government prosecutors have accused Lay of improperly using $75 million in personal bank loans to buy stock on margin, which is a violation of an obscure banking law known as Regulation U.

The government indicted him on four counts of bank fraud, each carrying up to 30 years of prison time if he's convicted.

Enron was the largest bankruptcy in corporate history, costing thousands of employees and investors billions of dollars, and set about the creation of new accounting regulation to prevent such a collapse from happening in the future.
