                                 ADDENDUM
                                    TO
                          STOCK OPTION AGREEMENT


          The following provisions are hereby incorporated into,
and are hereby made a part of, that certain Stock Option
Agreement dated                    , 199    (the "Option
Agreement") by and between Amdahl Corporation (the "Corporation")
and                     ("Optionee") evidencing the stock option
granted on such date to Optionee under the terms of the
Corporation's 1994 Incentive Plan, and such provisions shall be
effective immediately.  All capitalized terms used in this
Addendum, to the extent not otherwise specifically defined
herein, shall have the meanings assigned to such terms in the
Option Agreement.

                     LIMITED STOCK APPRECIATION RIGHT

          Optionee is hereby granted a limited stock appreciation
right in tandem with the option, exercisable upon the terms and
conditions set forth below:

          1.   Should a Hostile Take-Over occur at any time after
the option has been outstanding for a period of at least six (6)
months measured from the Effective Date of this Addendum
indicated below, then Optionee shall have the unconditional right
(exercisable during the thirty (30)-day period immediately
following the consummation of such Hostile Take-Over) to
surrender the option to the Corporation, to the extent the option
is at the time exercisable for vested shares of Common Stock.  In
return for the surrendered option, Optionee shall receive a cash
distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock
which are at the time vested under the surrendered option (or
surrendered portion of the option) over (ii) the aggregate
Exercise Price payable for such vested shares.

          2.   To exercise this limited stock appreciation right,
Optionee must, during the applicable thirty (30)-day exercise
period, provide the Corporation with written notice of the option
surrender in which there is specified the number of vested Option
Shares as to which the Option is being surrendered.  Such notice
must be accompanied by the return of Optionee's copy of the
Option Agreement, together with any written amendments to such
Agreement.  The cash distribution shall be paid to Optionee
within five (5) days following such delivery date, and neither
the approval of the Plan Administrator nor the consent of the
Board shall be required in connection with such option surrender
and cash distribution.  Upon receipt of such cash distribution,
the option shall be cancelled with respect to the vested Option
Shares subject to the surrendered option (or the surrendered
portion), and Optionee shall cease to have any further right to
acquire those Option Shares under the Option Agreement.  The
option shall, however, remain outstanding for the balance of the
Option Shares (if any) in accordance with the terms and
provisions of the Option Agreement, and the Corporation shall
issue to the Optionee a new stock option agreement (substantially
in the form of the surrendered Option Agreement) for those
remaining Option Shares.

          3.   For purposes of this limited stock appreciation
right, the following definitions shall be in effect:

               A HOSTILE TAKE-OVER shall be deemed to occur
should any person or related group of persons (other than the
Corporation or a person that directly or indirectly controls, is
controlled by, or is under common control with, the Corporation)
directly or indirectly acquire beneficial ownership (within the
meaning of Rule 13d-3 of the Securities Exchange Act of 1934, as
amended) of securities possessing more than fifty percent (50%)
of the total combined voting power of the Corporation's
outstanding securities pursuant to a tender or exchange offer
made directly to the Corporation's stockholders which the Board
does not recommend such stockholders to accept, and

               more than fifty percent (50%) of the securities
acquired in such tender or exchange offer are accepted from
holders other than the officers and directors of the Corporation
subject to the short-swing profit restrictions of Section 16 of
the Securities Exchange Act of 1934, as amended.

               The TAKE-OVER PRICE per share of Common Stock
shall be equal to the greater of (i) the Fair Market Value per
share on the date the option is surrendered to the Corporation in
connection with a Hostile Take-Over, as determined in accordance
with the valuation provisions of the Option Agreement, or (ii)
the highest reported price per share of Common Stock paid by the
tender offeror in effecting such Hostile Take-Over.  However, if
the surrendered option is designated as an Incentive Option in
the Grant Notice, then the Take-Over Price shall not exceed the
clause (i) price per share.

          4.   In no event may this limited stock appreciation
right be exercised when there is not a positive spread between
the Fair Market Value of the vested Option Shares and the
aggregate Exercise Price payable for such shares.  This limited
stock appreciation right shall in all events terminate upon the
expiration or sooner termination of the option term and may not
be assigned or transferred by Optionee.

          IN WITNESS WHEREOF, Amdahl Corporation has caused this
Addendum to be executed by its duly-authorized officer, and
Optionee has executed this Addendum, all as of the Effective Date
specified below.
