                                    PREAMBLE
                                    --------
                                        
1.   On 11 March 1997, AMD Saxonia, Dresdner Bank AG (in its capacity as "Agent"
and "Security Agent"), the Banks and Dresdner Bank Luxembourg S.A. (in its
capacity as "Paying Agent") entered into a syndicated loan agreement
(hereinafter "Loan Agreement") providing for credit facilities in an aggregate
total amount of DM 1.650.000.000 for the purpose of the partial financing of the
Project Costs more particularly set out therein. On 1 July 1997, Dresdner Bank
AG transferred its rights and obligations as Agent to Dresdner Bank Luxembourg
S.A. pursuant to (S) 22.11 of the Loan Agreement.

2.   As a result of ongoing developments in the production of microprocessors
and the presently anticipated conversion of the production process from
aluminium based metallisation to copper and the assumption of a US$ exchange
rate of DM 1.80 instead of the 

 
original notional exchange rate of DM 1.45 on which the original Management
Plan was based, the projected total investment costs of DM 2,430,000,000 on
which the terms of the Loan Agreement were based have increased by DM
687,000,000 to a total amount of DM 3,117,000,000.

3.   On 26 September 1997, AMD Inc. made available to AMD Saxonia an amount of
US$ 34,000,000 as an additional subordinated loan pursuant to Section 2.4 of the
Sponsors' Loan Agreement. The aforesaid additional subordinated loan of US$
34,000,000 will not be taken into account in satisfaction of the obligations of
AMD Inc. to make available to AMD Saxonia, via AMD Holding equity in the form of
ordinary share capital in an aggregate amount of DM 217,500,000 and the
obligations of AMD Inc. and/or AMD Holding to make subordinated loans or
additional equity contribution in cash to the reserves of AMD Saxonia in an
aggregate amount of DM 290,000,000 pursuant to the Sponsors' Support Agreement
and the Sponsors' Loan Agreement. In addition, the entire remaining additional
projected financing costs will be financed solely by AMD Inc. by way of equity
or additional subordinated loans to be made available to AMD Saxonia in an
amount of US$ 70,000,000 (which may be made available in either DM or US$) and
by the cash flow expected to be generated through AMD Inc.'s off-take and
reimbursement obligations under the AMD Holding and AMD Saxonia Wafer Purchase
Agreements and the AMD Holding and AMD Saxonia Research, Design and Development
Agreements.

4.   In the light of the circumstances and agreements referred to above, the
parties have agreed to changes to the Loan Agreement on the terms and conditions
more particularly set out below.

1.1  Terms and expressions defined in the Loan Agreement shall have the same
meaning when used in this Supplemental Agreement, unless the context requires
otherwise.

1.2  Unless the context requires otherwise, any reference to an Operative
Document or a Project Agreement shall be a reference to such Document or
Agreement as it shall have been, or from time to time be, amended, varied,
reissued, replaced, novated or supplemented in accordance with its terms,
including pursuant to this Supplemental Agreement.


                                     (S) 2
                        AMENDMENTS TO THE LOAN AGREEMENT
                                        
The Loan Agreement will be amended as more particularly set out below. The Loan

           3.5 of the Sponsors' Support Agreement and Section 2.5 of the
           Sponsors' Loan Agreement. In addition, AMD Inc. has made available to

           capital in an aggregate amount of DM 217,500,000. Furthermore AMD
           Inc. and/or AMD Holding has undertaken to make subordinated loans to
           or, in the case of AMD Holding, additional equity contributions in
           cash to the reserves of AMD Saxonia in an aggregate amount of the DM
           equivalent of US$ 200,000,000 (at least DM 290,000,000) and an
           additional amount equal to, or the equivalent of, US$ 70,000,000
           (which amount may be made available to AMD Saxonia by way of loan in
           either Dollars or Deutsche Marks and may be carried by AMD Saxonia as
           a Deutsche Mark denominated liability notwithstanding the currency in
           which it is made available to AMD Saxonia)."

           guaranty amount for any calendar year prescribed by the Guarantor
           pursuant to Schedule 63."


     (ii)  the second paragraph will be replaced as follows:

           to be 

 
           furnished together with the Drawdown Notice, as required below.
