Of course, the president cannot make a business deal and quid pro quo while he is president. As we know, however, it is done all the time. Peter had wanted to find a way to approach a soon to be departing president to act as a rainmaker. I don't like the fact that it was Clinton, but Peter had a duty to the shareholders to try to make the company worth as much as possible.
They did not have a written agreement. They did, however, have an understanding. Ed Rendell, among others, induced Peter to contribute to Al Gore and to Hillary. He also contributed to Gray Davis. Large companies usually hedge their bets by giving to both parties. That group engaged in a conspiracy to take his money with no intent to ever help his company. That is the conspiracy. It was Rendell and his gang who told Peter that the way to have any access to the president was to support his wife. He was told in no uncertain terms that such was the cost of admission. With his business advisor Jim Levin, Clinton actually was responsible for wrecking Peter's company.
Peter will have to speak for himself regarding a "misjudgment" statment. I think the misjudgment was trusting people who came to him and said we need your help in pulling a sting on Castro. At the time, Peter represented six South American governments. He agreed to join the sting and attempt to cause a serious rift between Castro and his Soviet benefactors, who were being overcharged by Castro for black market coffee.
