Verity, Inc.

Sunnyvale, CA  94089

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection
with the filing by VERITY, INC. (the "Registrant") of a Registration Statement
on Form S-8 (the "Registration Statement") with the Securities and Exchange
Commission covering the offering of up to an aggregate of 4,000,000 shares of
the Registrant's Common Stock, $0.001 par value (the "Shares"), pursuant to the
Registrant's 1996 Non-Statutory Stock Option Plan (the "Plan").

In connection with this opinion, we have examined the Registration Statement,
the Plan, the Registrant's Restated Certificate of Incorporation and Amended
and Restated Bylaws and such other documents, records, certificates, memoranda
and other instruments as we deem necessary as a basis for this opinion. We have
assumed the genuineness and authenticity of all documents submitted to us as
originals, the conformity to originals of all documents submitted to us as
copies thereof and the due execution and delivery of all documents where due
execution and delivery are a prerequisite to the effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion
that the Shares, when sold and issued in accordance with the Plan and the
Registration Statement, will be validly issued, fully paid and nonassessable
(except as to shares issued pursuant to certain deferred payment arrangements,
which will be fully paid and nonassessable when such deferred payments are made
in full).

We consent to the filing of this opinion as an exhibit to the S-8 Registration
Statement.

Sincerely,

COOLEY GODWARD LLP
