                              CAMDEN PROPERTY TRUST

                              5.875% NOTE DUE 2007

         This Security 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 15, 1996, as supplemented by the
Supplemental Indenture, dated as of February 15, 1996 (as so supplemented,
herein called the "Indenture"), between the Company and The Bank of New York
Trust Company of Florida, N.A., (formerly known as U.S. Trust Company of Texas,
N.A.) a national banking association organized under the laws of the United
States of America, as 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 $150,000,000.

         "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 (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 semi-annual 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% (twenty-five one hundredths 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 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 covenants set forth in Section 1012 of the Indenture shall be fully
applicable to this Security.

         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 any 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, 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 (and
premium or Make-Whole Amount, if any) or any interest on and any Additional
Amounts in respect thereof 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
Securities of each series at the time 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 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, trust manager or director, 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.
