INFORMATICA CORPORATION.

EXCERPT FROM QUESTION AND ANSWER SESSION:

JOE FARLEY, MORGAN STANLEY: And, can we assume that the option exchange is going
to proceed apace, or proceed into August when you have the stock swap?

EARL FRY, INFORMATICA: Yes, you can assume that we're in the process of actually
filing the Tender Offer with the SEC here in the next very short time frame,
next few days, and it will go ahead as planned as we discussed a couple of weeks
ago.

MR. FARLEY: OK, thanks.
