                             7.650% NOTE DUE 2010

          SECURITY CAPITAL PACIFIC TRUST, a real estate investment trust
organized and existing under the laws of the State of Maryland (hereinafter
called the "Company," which term shall include any successor under the Indenture
hereinafter referred to), for value received, hereby promises to pay to CEDE &
CO., or registered assigns, upon presentation, the principal sum of TWENTY
MILLION DOLLARS on August 1, 2010 and to pay interest on the outstanding
principal amount thereon from August 8, 1996, or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, semi-annually
in arrears on February 1 and August 1 in each year, commencing on February 1,
1997, at the rate of 7.650% per annum, until the entire principal hereof is paid
or made available for payment.  The interest so payable, and punctually paid or
duly provided for on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest which shall be the January 15 or July 15 (whether
or not a Business Day), as the case may be, next preceding such Interest Payment
Date.  Any such interest not so punctually paid or duly provided for shall
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 of this series
not more than 15 days and not less than 10 days prior to such Special Record
Date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required
<PAGE>
 
by such exchange, all as more fully provided in the Indenture.  Payment of the
principal of, Make-Whole Amount, if any, on, and interest on this Security will
be made at the office or agency of the Company maintained for that purpose in
the City of Boston, Commonwealth of Massachusetts, or elsewhere as provided in
the Indenture, in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
--------  -------                                                              
made by (i) check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) transfer to an account of
the Person entitled thereto located inside the United States.

          Each Security of this series is one of a duly authorized issue of
securities of the Company (herein called the "Securities"), issued and to be
issued in one or more series under an Indenture, dated as of February 1, 1994,
between the Company and Morgan Guaranty Trust Company of New York, as trustee,
as supplemented by a First Supplemental Indenture, dated as of February 2, 1994,
(as so supplemented, herein called the "Indenture") between the Company and
State Street Bank and Trust Company, as successor trustee (herein called the
"Trustee," which term includes any successor trustee under the Indenture with
respect to the series of which this Security is a part), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered.  This
Security is one of the series designated on the first page hereof, limited in
aggregate principal amount to $20,000,000.

          Securities of this series may be redeemed at any time at the option of
the Company, in whole or in part, upon notice of not more than 60 nor less than
30 days prior to the Redemption Date, at a redemption price equal to the sum of
(i) the principal amount of the Securities being redeemed plus accrued interest
thereon to the Redemption Date and (ii) the Make-Whole Amount, if any, with
respect to such Securities.

          The following definitions apply with respect to any redemption of the
Securities of this series at the option of the Company:

          "Make-Whole Amount" means, in connection with any optional redemption
or accelerated payment of any Security, the excess, if any, of (i) the aggregate
present value as of the date of such redemption or accelerated payment of each
dollar of principal being redeemed or paid and the amount of interest

                                      -2-
<PAGE>
 
(exclusive of interest accrued to the date of redemption or accelerated payment)
that would have been payable in respect of such dollar if such redemption or
accelerated payment had not been made, determined by discounting, on a
semiannual basis, such principal and interest at the Reinvestment Rate
(determined on the third Business Day preceding the date such notice of
redemption is given or declaration of acceleration is made) from the respective
dates on which such principal and interest would have been payable if such
redemption or accelerated payment had not been made, over (ii) the aggregate
principal amount of the Securities being redeemed or paid.

          "Reinvestment Rate" means .25% (one-fourth of one percent) plus the
arithmetic mean of the yields under the respective headings "This Week" and
"Last Week" published in the Statistical Release under the caption "Treasury
Constant Maturities" for the maturity (rounded to the nearest month)
corresponding to the remaining life to maturity, as of the payment date of the
principal being redeemed or paid.  If no maturity exactly corresponds to such
maturity, yields for the two published maturities most closely corresponding to
such maturity shall be calculated pursuant to the immediately preceding sentence
and the Reinvestment Rate shall be interpolated or extrapolated from such yields
on a straight-line basis, rounding in each of such relevant periods to the
nearest month.  For the purposes of calculating the Reinvestment Rate, the most
recent Statistical Release published prior to the date of determination of the
Make-Whole Amount shall be used.

          "Statistical Release" means the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded United
States government securities adjusted to constant maturities or, if such
statistical release is not published at the time of any determination under the
Indenture, then such other reasonably comparable index which shall be designated
by the Company.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Security and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Company, in each case, upon compliance by the Company with certain conditions
set forth in the Indenture, which provisions apply to this Security.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of, and the Make-Whole Amount, if any,
on, the Securities of this series may be declared due and payable in the manner
and with the effect provided in the Indenture.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and the Trustee shall have failed to institute any such proceeding
for 60 days after receipt of such notice, request and offer of indemnity. The
foregoing shall not apply to any suit instituted by the Holder of this Security
for the enforcement of any payment of principal hereof or any interest on or
after the respective due dates expressed herein.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities of each series of Securities then Outstanding affected
thereby. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such series,
to waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, Make-Whole Amount, if any,
on, and interest on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this

                                      -4-
<PAGE>
 
Security for registration of transfer at the office or agency of the Company in
any Place of Payment where the principal of, Make-Whole Amount, if any, on, and
interest on this Security are payable duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     No recourse under or upon any obligation, covenant or agreement contained
in the Indenture or in this Security, or because of any indebtedness evidenced
thereby, shall be had against any promoter, as such, or against any past,
present or future shareholder, officer or trustee, as such, of the Company or of
any successor, either directly or through the Company or any successor, under
any rule of law, statute or constitutional provision or by the enforcement of
any assessment or by any legal or equitable proceeding or otherwise, all such
liability being expressly waived and released by the acceptance of this Security
by the Holder thereof and as part of the consideration for the issue of the
Securities of this series.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused "CUSIP" numbers to be
printed on the Securities of this series as a convenience to the Holders of such
Securities.  No representation is made as to the correctness or accuracy of such
CUSIP numbers as printed on the Securities, and reliance may be placed only on
the other identification numbers printed hereon.
