The salient points were:

95% of West Bank, excluding ONLY the suburbs of Jeruslem
100% of Gaza
Joint sovereignty over East Jerusalem
Massive water desalination projects.
Line of credit of $40 billion to build resorts and infrastructure to attract tourists.
Limited repatriation of some 150,000 Palestianians into Israel.
Palestianian statehood.
Gradual relaxation of Israeli security presence at borders conditional upon cessation of terrorist attacks.
Open borders for tourism, commerce, etc.

OK, the offer was NOT perfect. But the Palestinians did NOT make a counter-offer. They just walked out. Even Arafat has admitted that this was a blunder, so the plan might have been the basis for further negotiations. If Arafat had not been such a damned fool, he would have remained at the bargaining table for as long as necessary until something mutually acceptable was worked out. Instead, he started a war.
