                                    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 non-
statutory stock option granted on such date to Optionee under the
terms of the Corporation's 1994 Stock Incentive Plan, and such
provisions shall be effective immediately.  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.

                           SPECIAL TAX ELECTIONS

          1.   Stock Withholding.  Optionee is hereby granted the
               -----------------
election to have the Corporation withhold, at the time the option
is exercised, a portion of the purchased Option Shares with an
aggregate Fair Market Value not to exceed one hundred percent
(100%) of the applicable Federal, state and local income and
employment tax withholding liability Optionee incurs in
connection with the option exercise (the "Withholding Taxes").

               Optionee's exercise of the election must be
effected in accordance with the following terms and conditions:

               a.   The election must be made on or before the
date the liability for the Withholding Taxes incurred in
connection with the option exercise is determined (the "Tax
Determination Date"), and Optionee must designate in such
election the percentage of the Withholding Taxes to be satisfied
through the Corporation's withholding of a portion of the
purchased Option Shares.

               b.   The election shall be irrevocable.

               c.   The election shall be subject to the approval
of the Plan Administrator, and none of the Option Shares shall
actually be withheld in satisfaction of the Withholding Taxes
incurred by Optionee in connection with the option exercise,
except to the extent the election is approved by the Plan
Administrator.

               d.   The Option Shares withheld pursuant to the
election shall be valued at Fair Market Value on the Tax
Determination Date. 

               e.   In no event may the number of shares
requested to be withheld exceed in Fair Market Value the dollar
amount of the Withholding Taxes incurred by Optionee in
connection with the option exercise.

               If the stock withholding election is made by
Optionee at the time when Optionee is an officer or director of
the Corporation subject to the short-swing profit restrictions of
Section 16(b) of the Securities Exchange Act of 1934, as amended,
then the following limitations, in addition to the preceding
provisions, shall also be applicable:

               a.   The election shall not become effective at
any time prior to the expiration of the six (6)-month period
measured from the Effective Date of this Addendum indicated
below, and no Option Shares shall accordingly be withheld in
connection with any Tax Determination Date which occurs before
the expiration of such six (6)-month period.

               b.   The stock withholding election must be made
in accordance with the following limitations:

                    (1)  Such election must be made at least six
(6) months before the Tax Determination Date, or

                    (2)  Both the exercise of such election and
the exercise of the option must occur concurrently within a
quarterly "window" period.  Quarterly window periods shall begin
on the third (3rd) business day following the date of public
release of each quarterly or annual summary statement of the
Corporation's sales and earnings and end on the earlier of the
twelfth (12th) business day following such release date or the
Tax Determination Date.

               c.   The six (6)-month periods specified in
clauses a. and b. shall not be applicable in the event of
Optionee's death or permanent disability.

          2.   Stock Delivery.  Optionee is hereby granted the
               --------------
election to deliver, at the time the option is exercised, one or
more shares of the Corporation's Common Stock previously acquired
by Optionee (other than in connection with the acquisition
triggering the Withholding Taxes) with an aggregate Fair Market
Value not to exceed one hundred percent (100%) of the Withholding
Taxes incurred in connection with such option exercise.

               Optionee's exercise of the election must be
effected in accordance with the following terms and conditions:

               a.   The election must be made on or before the
Tax Determination Date for the Withholding Taxes.

               b.   The election shall be irrevocable.

               c.   The election shall be subject to the approval
of the Plan Administrator, and none of the delivered shares of
Common Stock shall be accepted in satisfaction of the Withholding
Taxes incurred by Optionee in connection with the option
exercise, except to the extent the election is approved by the
Plan Administrator.

               d.   The shares of Common Stock delivered in
satisfaction of the Withholding Taxes shall be valued at Fair
Market Value on the Tax Determination Date. 

               e.   In no event may the number of delivered
shares exceed in Fair Market Value the dollar amount of the
Withholding Taxes incurred by Optionee in connection with the
exercise of the option.
