As to the story above about Hair's offer to resign for $500,000, a test cricketer on Radio 4 this teatime said that that was probably about the amount Hair could expect to earn from umpiring in the next four years. As (unlike footballers) age and infirmity would probably not rule him out of the game for some years to come, it seems a reasonable offer.
Apparently it was made directly to the ICC and intended to be a confidential agreement.
Not so much "give me a bung and I'll keep quiet", as "I'll retire as long as it doesn't cost me too much"
