RE: REGISTRATION STATEMENT ON FORM S-8 - RATIONAL SOFTWARE

CORPORATION 1994 EMPLOYEE STOCK PURCHASE PLAN
---------------------------------------------
Ladies and Gentlemen:
We have examined the Registration Statement on Form S-8 to be filed by
you with the Securities and Exchange Commission on or about November 3, 1997
(the "Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of 1,000,000 shares of Rational Software
Corporation Common Stock (the "Plan Shares"), to be issued pursuant to the
Rational Software Corporation 1994 Employee Stock Purchase Plan (the "Plan"). As
your counsel in connection with the transaction, we have examined the
proceedings taken and proposed to be taken in connection with the issuance and
sale of the Plan Shares.
It is our opinion that the Plan Shares, when issued and sold in the
manner described under the Plan, will be legally and validly issued, fully paid
and non-assessable.
We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement and any amendments thereto.
Very truly yours,
WILSON SONSINI GOODRICH & ROSATI
Professional Corporation
