Ladies and Gentlemen:
At your request, we have examined the Registration Statement on Form S-3
filed by Informatica Corporation, a Delaware corporation (the "Company"), with
the Securities and Exchange Commission on December 13, 2000 (the "Registration
Statement") relating to the registration under the Securities Act of 1933, as
amended, of up to 664,276 shares of the Company's common stock, $0.001 par value
(the "Stock"), being offered by certain selling stockholders specified therein
(the "Selling Stockholders").
As counsel to the Company, we have examined the proceedings taken by the
Company and the Selling Stockholders in connection with the sale by the Selling
Stockholders of up to 664,276 shares of Stock.
It is our opinion that the 664,276 shares of Stock that may be sold are
legally and validly issued, fully paid and nonassessable. We consent to the use
of this opinion as an exhibit to the Registration Statement and further consent
to all references to us in the Registration Statement, the prospectus
constituting a part thereof and any amendments thereto.
Very truly yours,
/s/ Morrison & Foerster LLP
