Administrator Trevor Birch has set an August 10 deadline for all the club's senior players to leave Pompey or reach compromise agreements over wages.
Just Ben Haim, on wages of £36,000 a week, and midfielder Liam Lawrence remain, but the Israeli says if the club close down it is not their fault.
"The blood is very much on their (PKF) hands," said Ben Haim.
The former Chelsea player added that he is prepared to come to a compromise, but will not be bullied into a deal.
Administrator Trevor Birch told the BBC: "Many of his former team-mates were in the same situation yet made big sacrifices and showed that the club is more important than any individual. Many non-football creditors, some small local businesses, have also told me that they'd be willing to take a personal financial hit in order to keep the club going."
