See also the Yahoo/Bing deal which didn't work out as well. Microsoft didn't end up actually hitting the targets, and convinced Yahoo to take less; and Yahoo also didn't reduce employee count anywhere near plan on searchy/advertising stuff, so they missed targets on revenue and cost and user experience.
It was guaranteed revenue IIUC, something like "If you do not make at least $150M from this deal, Google will pay you the difference." That makes the deal a no-brainer for AOL, but puts Google on the hook for any shortfall, which could have potentially ended up bankrupting the company.
CPC = Cost per Click (cost per 1 click)
