_______________________
(1)  Based upon Oracle Corporation's estimate of the number of shares of Common
     Stock that will be issued pursuant to the 401(k) Savings and Investment
     Plan.  This Registration Statement shall also cover any additional shares
     of Common Stock which become issuable under the 401(k) Savings and
     Investment Plan by reason of any stock dividend, stock split,
     recapitalization or any other similar transaction effected without the
     receipt of consideration which results in an increase in the number of the
     Registrant's outstanding shares of Common Stock.

(2)  The securities include certain rights associated with the Common Stock
     pursuant to a Rights Agreement dated December 3, 1990, as amended on
     January 24, 1994 and March 31, 1998.

(3)  Estimated solely for purposes of calculating the registration fee in
     accordance with Rules 457(c) and (h) under the Securities Act.  The
     computation with respect to shares of Common Stock issuable pursuant to the
     401(k) Savings and Investment Plan is based upon the average high and low
     sale prices of the Common Stock of Oracle Corporation as reported on the
     Nasdaq National Market on September 4, 1998.

(4)  Pursuant to Rule 416(c) under the Securities Act of 1933, this Registration
     Statement also covers an indeterminate amount of interests to be offered or
     sold pursuant to the 401(k) Savings and Investment Plan.  Includes related
     interests in the trust created pursuant to the 401(k) Savings and
     Investment Plan.  The required information regarding beneficial interests
     is subsumed in the information above regarding Common Stock.

Item 9.         UNDERTAKINGS.
                ------------ 

          The undersigned Registrant hereby undertakes:

                (1)     to file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement to include
any material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

                (2)     that, for purposes of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                (3)     to remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act, and each filing of the 401(k) Savings and Investment Plan's annual
report pursuant to Section 15(d) of the Exchange Act, that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

          Insofar as the indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in a successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the Registrant will,
unless in the opinion of its counsel the question has already been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

     Plan.  This Registration Statement shall also cover any additional shares
     of Common Stock which become issuable under the 401(k) Savings and
     Investment Plan by reason of any stock dividend, stock split,
     recapitalization or any other similar transaction effected without the

     Registrant's outstanding shares of Common Stock.

(2)  The securities include certain rights associated with the Common Stock
     pursuant to a Rights Agreement dated December 3, 1990, as amended on

     accordance with Rules 457(c) and (h) under the Securities Act.  The
     computation with respect to shares of Common Stock issuable pursuant to the
     401(k) Savings and Investment Plan is based upon the average high and low
     sale prices of the Common Stock of Oracle Corporation as reported on the
     Nasdaq National Market on September 4, 1998.

(4)  Pursuant to Rule 416(c) under the Securities Act of 1933, this Registration
     Statement also covers an indeterminate amount of interests to be offered or
     sold pursuant to the 401(k) Savings and Investment Plan.  Includes related
     interests in the trust created pursuant to the 401(k) Savings and
     Investment Plan.  The required information regarding beneficial interests
     is subsumed in the information above regarding Common Stock.

Item 9.         UNDERTAKINGS.
                ------------ 

          The undersigned Registrant hereby undertakes:

                (1)     to file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement to include
any material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

                (2)     that, for purposes of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                (3)     to remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act, and each filing of the 401(k) Savings and Investment Plan's annual
report pursuant to Section 15(d) of the Exchange Act, that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

          Insofar as the indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in a successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the Registrant will,
unless in the opinion of its counsel the question has already been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
