Prce, former Bosnian state presidency member Ante Jelavic, and members of the Mostar-based bank's management board Miroslav Rupcic, Ivica Karlovic and friar Ivan Sevo, are charged with mismanaging aid which the Croatian government sent to Croats in Bosnia-Herzegovina.
Prosecutor John McNair of Canada, who is conducting the trial, said before a three-member trial chamber in Sarajevo that Prce was willing to plead guilty and he therefore sought approval to start formal negotiations.
Prce's attorney Zarko Bulic confirmed the plea bargain.
Judge Michael Simmons of Great Britain, who chairs the trial chamber, agreed with the motion of the prosecution and Prce's counsel, scheduling a discussion on the plea bargain for tomorrow.
According to unofficial sources, Prce was willing to plead guilty to those counts in the indictment which charge him with failure to ensure, in his capacity as defence minister, efficient control of the financial operations of the ministry through which numerous financial transactions with Herzegovacka Banka were performed.
It is speculated that Prce could be sentenced to a prison term of up to five years.
His attorney today submitted a request to be relieved of taking part in the defence, which is to take effect once the plea bargain is approved.
Defence counsel for Jelavic and Sevo confirmed their withdrawal from the trial, while defendants Rupcic and Karlovic hired an attorney from Mostar to represent them.
Jelavic's attorney Josip Muselimovic said that the withdrawing defence counsel considered their involvement in the trial purposeless because all of their previous objections and motions had been dismissed.
Judge Simmons accepted the defence counsel's decision and added that he would appoint new defence counsel if this was not done by the accused.
Simmons announced the presentation of opening statements by the prosecution for October 14, and the first witness is expected to take the stand on October 18.
