December 20, 2003 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually on December 1
and June 1 in each year, commencing June 1, 2004, at the rate of
11.75% per annum until the principal hereof is paid or made available for
payment.  The interest so payable, and

may be, next preceding such Interest Payment Date.  Any such interest not so punctually paid or
duly provided for will forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange or other market on which the Securities may be listed, and
upon such notice as may be required by such exchange or market, all as more
fully provided in said Indenture. 
Payment of the principal of (and premium, if any) and interest on this
Security will be made at the Corporate Trust Office or the office or agency of
the Company maintained for that purposes in the Borough of Manhattan, The City

debts; provided, however, that at the option of the Company A-1

  SILICON GRAPHICS, INC. 11.75% SENIOR SECURED NOTE
DUE 2009 1.             Interest This Security shall bear interest at 11.75% per
annum in the manner set forth in the Indenture and the face of this
Security.  In the event that principal
hereof or any portion of such principal is not paid when due (whether upon
acceleration pursuant to Section 6.02 of the Indenture, upon the date set for
payment of the Redemption Price pursuant to paragraph 5 hereof, upon the date
set for payment of a Fundamental Change Redemption Price pursuant to paragraph
6 hereof or upon the Stated Maturity of this Security), then in each such case
the overdue amount shall bear interest at the rate of 11.75% per annum,
compounded semiannually (to the extent that the payment of such interest shall
be legally enforceable), which interest shall accrue from the date such overdue
amount was due to the date payment of such amount, including interest thereon,
has been made or duly provided for.  All
such interest shall be payable on demand. 2.             Method of Payment Subject to the terms and conditions of the
Indenture, the Company will make payments in respect of the Securities to the
persons who are registered Holders of Securities at the close of business on
the Redemption Date, Fundamental Change Repurchase Date or Stated Maturity, as
the case may be.  Holders must surrender
Securities to a Paying Agent to collect such payments in respect of the
Securities.  The Company will pay cash
amounts in money of the United States that at the time of payment is legal
tender for payment of public and private debts. 
However, the Company may make such cash payments by check mailed to the
address of, or by wire transfer to the account of, the person entitled to such
payment. 3.             Paying Agent and
Registrar Initially, U.S. Bank National Association, a
national banking association (the Trustee), will
act as Paying Agent and Registrar.  The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice, other than notice to the Trustee.  The Company or any of its Subsidiaries or any
of their Affiliates may act as Paying Agent, Registrar or co-registrar. 4.             Indenture The Company issued the Securities under an Indenture
dated as of December 24, 2003 (the Indenture),
between the Company and the Trustee. 
Capitalized terms used herein and not defined herein have the meanings
ascribed A-1 
   thereto in the
Indenture.  The Securities are subject to
all such terms, and Securityholders are referred to the Indenture for a
statement of those terms. The Securities are secured obligations of the
Company pursuant to certain Junior Priority Security Documents (as defined in
the Indenture) and limited to $230,591,000 aggregate principal amount (subject
to Sections 2.02 and 2.07 of the Indenture). 5.             Redemption at the
Option of the Company Prior to June 1, 2004, the Securities will not
be redeemable at the option of the Company. 
Beginning on June 1, 2004, the Company may redeem the Securities
for cash as a whole at any time, or from time to time in part, upon not less
than 10 days nor more than 60 days notice at the following prices (the Redemption Price) (expressed as percentages of the
principal amount), together with accrued and unpaid interest to, but excluding,
the Redemption Date.  Beginning on
June 1, 2004, the Redemption Price shall be 104% of the principal amount
plus accrued and unpaid interest thereon. 
Beginning on June 1, 2005, the Redemption Price shall be 103% plus
accrued and unpaid interest thereon. 
Beginning on June 1, 2006, the Redemption Price shall be 102% plus
accrued and unpaid interest thereon. 
Beginning on June 1, 2007, the Redemption Price shall be 101% plus
accrued and unpaid interest thereon. 
Beginning on June 1, 2008, the Redemption Price shall be 100% plus
accrued and unpaid interest thereon. If any Redemption Date is an Interest Payment Date,
then the interest payable on such date shall be paid to the Holder of the
Security on the next preceding Regular Record Date.  No Securities may be redeemed by the Company
if an Event of Default with respect to the payment of interest on the
Securities has occurred and is continuing. No sinking fund is provided for the Securities. Notice of redemption at the option of the Company
will be mailed at least 10 days but not more than 60 days before the Redemption
Date to each Holder of Securities to be redeemed at the Holders registered
address.  If money sufficient to pay the
Redemption Price, together with accrued interest to, but excluding, the Redemption
Date, of all Securities (or portions thereof) to be redeemed on the Redemption
Date is deposited with the Paying Agent prior to or on the Redemption Date, on
and after such date interest ceases to accrue on such Securities or portions
thereof.  Securities in denominations
larger than $1,000 of principal amount may be redeemed in part but only in
multiples of $1,000 of principal amount. 6.             Redemption at the
Option of the Holder Upon a Fundamental Change (a)           At the option of the Holder and
subject to the terms and conditions of the Indenture, the Company shall become
obligated to redeem the Securities A-2 
   held by such Holder on the
date (the Fundamental Change Repurchase Date)
(or if such date is not a Business Day, the next succeeding Business Day) that
is 45 days after the date of the Companys notice of such Fundamental Change
(as defined in the Indenture) occurring prior to June 1, 2009 at 100% of the
principal amount.  In each case, the
Company shall also pay accrued but unpaid interest, if any, on such Securities
to, but excluding, the Fundamental Change Repurchase Date; provided that if
such Fundamental Change Repurchase Date is an Interest Payment Date, then the
interest payable on such date shall be paid to the Holder of the Security on the
next preceding Regular Record Date. 
Securities in denominations larger than $1,000 of principal amount may
be redeemed in part in connection with a Fundamental Change, but only in
multiples of $1,000 of principal amount. (b)           Holders have the right to withdraw
any Fundamental Change Redemption Notice by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the
Indenture. (c)           If cash sufficient to pay the
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date, of all Securities or
portions thereof to be purchased as of the Fundamental Change Repurchase Date
is deposited with the Paying Agent on or prior to the Fundamental Change
Repurchase Date, interest ceases to accrue on such Securities (or portions
thereof) on and after the Fundamental Change Repurchase Date, and the Holder
thereof shall have no other rights as such (other than the right to receive the
Fundamental Change Redemption Price, together with accrued interest to, but
excluding, the Fundamental Change Repurchase Date, upon surrender of such
Security). 7.             Denominations;
Transfer; Exchange The Securities are in registered form, without
coupons, in denominations of $1,000 of principal amount and multiples of
$1,000.  A Holder may transfer or
exchange Securities in accordance with the Indenture.  The Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and to
pay any taxes and fees required by law or permitted by the Indenture.  The Registrar need not transfer or exchange
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities in respect of which a Fundamental Change Redemption Notice has been
given and not withdrawn (except, in the case of a Security to be purchased in
part, the portion of the Security not to be purchased) or any Securities for a
period of 15 days before a selection of Securities to be redeemed. 8.             Persons Deemed
Owners The registered Holder of this Security may be
treated as the owner of this Security for all purposes. A-3 
   9.             Unclaimed Money or
Securities The Trustee and the Paying Agent shall return to the
Company upon written request any money or securities held by them for the
payment of any amount with respect to the Securities that remains unclaimed for
two years, provided, however, that the Trustee or such Paying Agent, before
being required to make any such return, shall at the expense of the Company
cause to be published once in a newspaper of general circulation in The City of
New York or mail to each such Holder notice that such money or securities
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication or mailing, any unclaimed
money or securities then remaining will be returned to the Company.  After return to the Company, Holders entitled
to the money or securities must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another
person. 10.          Amendment; Waiver Subject to certain exceptions set forth in the
Indenture, (i) the Indenture or the Securities may be amended with the written
consent of the Holders of at least a majority in aggregate principal amount of

amount of the Securities at the time outstanding, may declare all the
Securities to be due and payable immediately.

the occurrence of such Events of Default. Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture.

it receives reasonable indemnity or security.

principal amount of the Securities at the time outstanding may direct the
Trustee in its exercise of any trust or power. 
The Trustee may withhold from Securityholders notice of any continuing
Default (except a Default in payment of amounts specified in  (i) or (ii) above) if it determines that
withholding notice is in their interests. 12.          Lien Subordination
and Sharing.This Security is secured by Junior Priority Liens upon the Collateral
pursuant to certain Junior Priority Security Documents.  The Junior Priority Liens upon any and all
Collateral are, to the extent and in the manner provided in the Intercreditor
Agreement, subordinate in ranking to all present and future Senior Priority
Liens as set forth in the Indenture and the Intercreditor Agreement. 13.          Trustee Dealings with
the Company The Trustee under the Indenture, in its individual
or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with and collect obligations owed to it by the Company or its
Affiliates and may otherwise deal with the Company or its Affiliates with the
same rights it would have if it were not Trustee. 14.          No Recourse Against
Others A director, officer, employee or stockholder, as
such, of the Company shall not have any liability for any obligations of the
Company under the Securities or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation.  By accepting a Security, each Securityholder
waives and releases all such liability. 
The waiver and release are part of the consideration for the issue of
the Securities. 15.          Authentication This Security shall not be valid until an authorized
officer of the Trustee manually signs the Trustees Certificate of
