1) Reassure current Sun customers that their investments will be not only protected but enhanced.
2) Reassure Sun employees that they are a strategically essential element of Oracle's present and future.
3) Reassure Sun and Oracle investors that the acquisition will enrich Oracle not only technologically but also financially.
Here are Ellison's exact words about Sun's financial health and prospects via my transcription from the Oracle webcast:
"And how soon will that [profitability] occur? How long do investors have to wait? Not at all; not at all. We'll be profitable this-in February. We'll be profitable in March. We'll be profitable in April-and when I say 'we': the Sun business. We'll be profitable in May.
"Sun will be contributing to Oracle's profits from the first month we own the company. And for the first full year we own the company starting in June, we will make at least a billion and a half dollars in operating profit [from Sun], as we promised, because the Sun business is gonna grow.
"Sun has a fabulous installed base, a fabulous group of customers, a wonderful pipeline of technology-and we just have to do a better job of taking this wonderful engineering output and delivering it to customers."
