     WASHINGTON REAL ESTATE INVESTMENT TRUST, a Maryland real estate 
investment trust  (hereinafter called the "Trust," which term shall include 
any successor trust or entity under the Indenture hereinafter referred to), 
for value received, hereby promises to pay to Cede & Co., a nominee of The 
Depository Trust Company ("DTC"), or its registered assigns, upon 
presentation, the principal amount of SIXTY MILLION DOLLARS ($60,000,000), on 
the Stated Maturity Date specified above (or any earlier redemption date or 
repurchase date) (each such Stated Maturity Date, redemption date or 
repurchase date being hereinafter referred to as the "Maturity Date" with 
respect to the principal repayable on such date) and to pay interest thereon, 
at the Interest Rate per annum specified above to February 25, 2008 (the 
"Remarketing Date"), and thereafter, subject to the terms and conditions set 
forth herein, at the Interest Rate determined by the Remarketing Dealer (as 
defined below) in accordance with the procedures set forth below (the 
"Interest Rate to Maturity"), until the principal hereof is paid or duly made 
available for payment. The Trust will pay interest in arrears on each 
Interest Payment Date, if any, specified above (each, an "Interest Payment 
Date"), commencing with the first Interest Payment Date next succeeding the 
Original Issue Date specified above, and on the Maturity Date. Interest on 
this MOPPRS will be computed on the basis of a 360-day year of twelve 30-day 
months.

     If, pursuant to the Remarketing Agreement, dated as of the date hereof 
(the "Remarketing Agreement), among Merrill Lynch, Pierce, Fenner & Smith 
Incorporated, as Remarketing Dealer (the "Remarketing Dealer"), and the 
Trust, the Remarketing Dealer elects to remarket the MOPPRS, then, except as 
otherwise set forth herein, (i) this MOPPRS shall be subject to mandatory 
tender to the Remarketing Dealer for remarketing on the Remarketing Date, on 
the terms and subject to the conditions set forth herein, and (ii) on and 
after the Remarketing Date, this MOPPRS shall bear interest at the Interest 
Rate to Maturity determined by the Remarketing Dealer in accordance with the 
procedures set forth in Section 3 herein. 

     Interest on this MOPPRS will accrue from, and including, the immediately 
preceding Interest Payment Date to which interest has been paid or duly 
provided for (or from, and including, the Original Issue Date if no interest 
has been paid or duly provided for) to, but excluding, the applicable 
Interest Payment Date or the Maturity Date, as the case may be. The interest 
so payable, and punctually paid or duly provided for, on any Interest Payment 
Date will, subject to certain exceptions described herein, be paid to the 
person in whose name this MOPPRS (or one or more predecessor MOPPRS) is 
registered at the close of business on the fifteenth calendar day (whether or 
not a Business Day, as defined below) immediately preceding such Interest 
Payment Date (the "Regular Record Date"); provided, however, that interest 
payable on the Maturity Date will be payable to the person to whom the 
principal hereof and premium, if any, hereon shall be payable. Any such 
interest not so punctually paid or duly provided for ("Defaulted Interest") 
will forthwith cease to be payable to the holder on any Regular Record Date, 
and shall be paid to the person in whose name this MOPPRS is registered at 
the close of business on a special record date (the "Special Record Date") 
for the payment of such Defaulted Interest to be fixed by the Trustee 
hereinafter referred to, of which notice  shall be given to the holder of 
this MOPPRS by the Trustee not more than 15 days nor 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 this MOPPRS 

                                         -2-




may be listed, and upon such notice as may be required by such exchange, all 
as more fully provided for in the Indenture.

     Payment of principal, premium, if any, and interest in respect of this 
MOPPRS due on the Maturity Date will be made in immediately available funds 
upon presentation and surrender of this MOPPRS (and, with respect to any 
applicable repayment of this MOPPRS, a duly completed election form as 
contemplated on the reverse hereof) at the corporate trust office of the 
Trustee maintained for that purpose in the Borough of Manhattan, The City of 
New York, currently located c/o First Chicago Trust Company of New York, 14 
Wall Street, Eighth Floor - Window 2, New York, New York, 10005, or at such 
other paying agency in The City of New York, State of New York, as the Trust 
may determine. Payment of interest due on any Interest Payment Date other 
than the Maturity Date will be made by check mailed to the address of the 
person entitled thereto as such address shall appear in the Security Register 
kept for the MOPPRS pursuant to Section 305 of the Indenture. 

     If any Interest Payment Date or the Maturity Date falls on a day that is 
not a Business Day, the required payment of principal, premium, if any, 
and/or interest shall be made on the next succeeding Business Day with the 
same force and effect as if made on the date such payment was due, and no 
interest shall accrue with respect to such payment for the period from and 
after such Interest Payment Date or the Maturity Date, as the case may be.

     As used herein, "Business Day" means any day other than a Saturday, 
Sunday or a day on which banking institutions in The City of New York are 
authorized or required by law, regulation, executive order or governmental 
decree to be closed. 

     The Trust is obligated to make payment of principal, premium, if any, 
and interest in respect of this MOPPRS in U.S. Dollars.

     Reference is hereby made to the further provisions of this MOPPRS set 
forth on the reverse hereof.

     Unless the Certificate of Authentication hereon has been executed by the 
Trustee by manual signature, this MOPPRS shall not be entitled to any benefit 
under the Indenture or be valid or obligatory for any purpose. 

                                         -3-




      IN WITNESS WHEREOF, Washington Real Estate Investment Trust has caused 
this MOPPRS to be duly executed this 25th day of February, 1998.

                                (Medium-Term Note)

     1.   INDENTURE.  (a) This MOPPRS is one of a duly authorized issue of 
senior debt securities of the Trust (the "Securities") issued under an 
Indenture, dated as of August 1, 1996 (the "Indenture"), among theTrust and 
The First National Bank of Chicago, as Trustee (herein called the  "Trustee," 
which term includes any successor trustee under the Indenture with respect to 
the MOPPRS), 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 Trust, the 
Trustee, and the holders of the MOPPRS, and of the terms upon which the 
MOPPRS are authenticated and delivered. This Security is designated as 
"6.898% MandatOry Par Put Remarketed Securities-SM- Due February 25, 2018" 
("MOPPRS"), which MOPPRS are limited to $60,000,000 aggregate principal 
amount, subject to the provisions of the Indenture. All terms used but not 
defined in this MOPPRS shall have the meanings assigned to such terms in the 
Indenture.  Except where the context otherwise requires, all references in 
this MOPPRS to "herein" or "hereof" or similar terms shall include the 
Indenture.

     (b)  This MOPPRS is issuable only in registered form without coupons in 
minimum denominations of U.S. $1,000 and integral multiples thereof. 

     (c)  This MOPPRS will not be subject to any sinking fund. 

     2.   MANDATORY TENDER. Provided that on a Business Day not later than 
five Business Days prior to the Remarketing Date the Remarketing Dealer 
notifies the Trust and the Trustee of its election to purchase the MOPPRS on 
the Remarketing Date (the "Notification Date"), the MOPPRS shall be subject 
to mandatory tender to the Remarketing Dealer, and the Remarketing Dealer 
shall be obligated to purchase the MOPPRS, for remarketing on the Remarketing 
Date, subject in each case to the conditions described herein and set forth 
in the Remarketing Agreement.

     3.   DETERMINATION OF INTEREST RATE TO MATURITY. (a) Subject to the 
Remarketing Dealer's election to remarket the MOPPRS as provided in Section 2 
hereof and the Remarketing Agreement, the Interest Rate to Maturity shall be 
determined by the Remarketing Dealer by 3:30 p.m., New York City time, on and 
as of the third Business Day immediately preceding the Remarketing Date (the 
"Determination Date") to the nearest one hundred-thousandth (0.00001) of one 
percent per annum, and will be equal to the sum of 5.598% (the "Base Rate") 
plus the Applicable Spread, which will be based on the Dollar Price of the 
MOPPRS.

     The "Applicable Spread" will be the lowest bid indication, expressed as 
a spread (in the form of a percentage or in basis points) above the Base 
Rate, obtained by the Remarketing Dealer on the Determination Date from the 
bids quoted by five Reference Corporate Dealers for the full aggregate 
principal amount of the MOPPRS at the Dollar Price, but assuming (i) an issue 
date equal to the 

                                         -6-




Remarketing Date, with settlement on such date without accrued interest, (ii) 
a maturity date equal to the Stated Maturity Date of the MOPPRS, and (iii) a 
stated annual interest rate, payable semi-annually on each Interest Payment 
Date, equal to the Base Rate plus the spread bid by the applicable Reference 
Corporate Dealer. If fewer than five Reference Corporate Dealers bid as 
described above, then the Applicable Spread shall be the lowest of such bid 
indications obtained as described above. The Interest Rate to Maturity 
announced by the Remarketing Dealer, absent manifest error, shall be binding 
and conclusive upon the beneficial owners and Holders of the MOPPRS, the 
Trust and the Trustee.

     "Dollar Price" means the present value, as of the Remarketing Date, of 
the Remaining Scheduled Payments discounted to the Remarketing Date, on a 
semi-annual basis (assuming a 360-day year consisting of twelve 30-day

     "Reference Corporate Dealers" mean leading dealers of publicly traded 
debt securities of the Trust in The City of New York (which may include the 
Remarketing Dealer or one of its affiliates) selected by the Remarketing 
Dealer.

per annum equal to the semi-annual equivalent yield to maturity or 
interpolated (on a day count basis) yield to maturity of the Comparable 
Treasury Issues, assuming a price for the Comparable Treasury Issues 
(expressed as a percentage of its principal amount), equal to the Comparable 
Treasury Price for the Remarketing Date.

     "Comparable Treasury Issues" means the United States Treasury security 
or securities selected by the Remarketing Dealer as having an actual or 
interpolated maturity or maturities comparable to the remaining term of the 
MOPPRS being remarketed.

     "Comparable Treasury Price" means, with respect to the Remarketing Date, 
(a) the offer prices for the Comparable Treasury Issues (expressed in each 
case as a percentage of its principal amount) on the Determination Date, as 
set forth on "Telerate Page 500" (or such other page as may replace Telerate 
Page 500), or (b) if such page (or any successor page) is not displayed or 
does not contain such offer prices on the Determination Date, (i) the average 
of the Reference Treasury Dealer Quotations for the Remarketing Date, after 
excluding the highest and lowest of such Reference Treasury Dealer 
Quotations, or (ii) if the Remarketing Dealer obtains fewer than four such 
Reference Treasury Dealer Quotations, the average of all such Reference 
Treasury Dealer Quotations. "Telerate Page 500" means the display designated 
as "Telerate Page 500" on Dow Jones Markets Limited (or such other page as

Markets Limited.

Reference Treasury Dealer and the Remarketing Date, the offer prices for the 
Comparable Treasury Issues (expressed in each case as a percentage of its 
principal amount) quoted to the Remarketing Dealer by such Reference Treasury 
Dealer by 3:30 p.m., New York City time, on the Determination Date.

Corporation, Lehman Brothers Inc., Merrill Lynch, Pierce, Fenner & Smith 
Incorporated, Morgan Stanley & Co. Incorporated and Salomon Brothers Inc and 
their respective successors; provided, however, that if any of the foregoing

dealer in The City of New York (a "Primary Treasury Dealer"), the Remarketing 
Dealer shall substitute therefor another Primary Treasury Dealer.

     "Remaining Scheduled Payments" means, with respect to the MOPPRS, the 
remaining scheduled payments of the principal thereof and interest thereon, 
calculated at the Base Rate only, that would be due after the Remarketing

MOPPRS, the amount of the next succeeding scheduled interest payment thereon, 
calculated at the Base Rate only, will be reduced by the amount of interest 
accrued thereon, calculated at the Base Rate only, to the Remarketing Date.

     (b)  Notwithstanding any provision herein to the contrary, upon the 
occurrence of any Termination Event (as defined below), the Remarketing 
Dealer, in its sole discretion at any time between the Determination Date and

3(a) hereof, except that for purposes of determining the new Interest Rate to 
Maturity pursuant to this paragraph, the Determination Date referred to

Remarketing Dealer shall notify the Trust, the Trustee and DTC by telephone, 
confirmed in writing (which may include facsimile or other electronic 
transmission), by 4:00 p.m., New York City time, on the date of such 
election, of the new Interest Rate to Maturity applicable to the MOPPRS. 
Thereupon, such new Interest Rate to Maturity shall supersede and replace any 
Interest Rate to Maturity previously determined by the Remarketing Dealer 
and, absent manifest error, shall be binding and conclusive upon the 
beneficial owners and Holders of the MOPPRS on or after the Remarketing Date, 
the Trust and the Trustee.

     "Termination Event" means any event as specified in Section 11(b) of the 
Remarketing Agreement.

     4.   REPURCHASE. In the event that (i) the Remarketing Dealer for any 
reason does not notify the Trust of the Interest Rate to Maturity by 4:00 
p.m., New York City time, on the Determination Date, or (ii) prior to the 
Remarketing Date, the Remarketing Dealer has resigned and no successor has 
been appointed on or before the Determination Date, or (iii) the Remarketing 
Dealer has terminated the Remarketing Agreement pursuant to Section 8 or 
Section 11 thereof at any time after the Remarketing Dealer elects on the 
Notification Date to remarket the MOPPRS, or (iv) the Remarketing Dealer for 
any reason does not elect to purchase the MOPPRS for remarketing on the 
Remarketing Date, or (v) the Remarketing Dealer for any reason does not 
purchase all tendered MOPPRS on the Remarketing Date, the Trust shall 
repurchase the MOPPRS as a whole on the Remarketing Date at a price equal to 
100% of the principal amount of the MOPPRS plus all accrued 


                                         -8-




and unpaid interest, if any, on the MOPPRS to the Remarketing Date. In any 
such case, payment will be made by the Trust through the Trustee to the DTC 
participant of each tendering beneficial owner of MOPPRS, by book-entry 
through DTC by the close of business on the Remarketing Date against delivery 
through DTC of such beneficial owner's tendered MOPPRS.

     5.   REDEMPTION.   (a) This MOPPRS will be subject to redemption at the 
option of the Trust from the Remarketing Dealer on the Remarketing Date, in 
whole but not in part, at the Optional Redemption Price. To exercise its 
option to redeem the MOPPRS, the Trust must notify the Remarketing Dealer and 
the Trustee not later than the Business Day immediately preceding the 
Determination Date.  The "Optional Redemption Price" shall be the greater of 
(i) 100% of the principal amount of the MOPPRS and (ii) the sum of the 
present values of the Remaining Scheduled Payments thereon, as determined by 
the Remarketing Dealer, discounted to the Remarketing Date on a semi-annual 
basis (assuming a 360-day year consisting of twelve 30-day months) at the 
Treasury Rate, plus in either case accrued and unpaid interest from the 
Remarketing Date on the principal amount being redeemed to the date of 
redemption. If the Trust elects to redeem the MOPPRS, it shall pay the 
redemption price therefor in same-day funds by wire transfer to an account 
designated by the Remarketing Dealer on the Remarketing Date. 

     (b) After the Remarketing Date, this MOPPRS shall be subject to 
redemption at the option of the Trust, in whole or in part, at any time, in 
increments of U.S. $1,000 (provided that any remaining principal amount 
hereof shall be at least U.S. $1,000), at a redemption price determined by 
the Trust equal to the sum of (i) the principal amount of the MOPPRS being 
redeemed, plus accrued and unpaid interest thereon to the redemption date, 
and (ii) the Make-Whole Amount, if any (the "Redemption Price"). For purposes 
of redemption after the Remarketing Date, interest shall be calculated at the 
Interest Rate to Maturity. 

     If notice has been given as provided in the Indenture and funds for the 
redemption of any MOPPRS called for redemption shall have been made available 
on the redemption date referred to in such notice, such MOPPRS shall cease to 
bear interest on the date fixed for such redemption specified in such notice 
and the only right of the Holders from and after the redemption date shall be 
to receive payment of the Redemption Price upon surrender of such MOPPRS in 
accordance with such notice.

     Notice of any optional redemption of any MOPPRS shall be given to 
Holders at their addresses, as shown in the security register for the MOPPRS, 
not less than 30 nor more than 60 days prior to the date fixed for 
redemption. The notice of redemption shall specify, among other items, the 
Redemption Price and the principal amount of the MOPPRS held by such Holder 
to be redeemed. If less than all of the MOPPRS are to be redeemed, the 
particular MOPPRS to be redeemed shall be selected by such method as the 
Trustee deems fair and appropriate. 

     "Make-Whole Amount" shall mean, in connection with any optional 
redemption of any MOPPRS, the excess, if any, of (i) the aggregate present 
value as of the date of such redemption of each dollar of principal being 
redeemed and the amount of any interest (exclusive of interest accrued 


                                         -9-




to the date of redemption) that would have been payable in respect of each 
such dollar if such redemption had not been made, determined by discounting, 
on a semi-annual basis, such principal and interest at the applicable 
Reinvestment Rate (determined on the third Business Day preceding the date 
such notice of redemption is given) from the respective dates on which such 
principal and interest would have been payable if such redemption had not 
been made, over (ii) the aggregate principal amount of the MOPPRS being 
redeemed.

     "Reinvestment Rate" shall mean .25% plus the yield on treasury 
securities at a constant maturity for the most recent week under the heading 
"Week Ending" published in the most recent 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. 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 
purpose 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" shall mean the statistical release designated 
"H.15(519)" or any successor publication that is published weekly by the 
Federal Reserve System and that 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 that shall be 
designated by the Trust. 

     6.   EFFECT OF EVENTS OF DEFAULT. If an Event of Default, as defined in 
the Indenture, shall occur and be continuing, the principal of, and the 
Make-Whole Amount, if any, on the MOPPRS may be declared due and payable in 
the manner and with the effect provided in the Indenture.

     7.   DEFEASANCE. The Indenture contains provisions for defeasance of (i) 
in the case of this clause (i), after the Remarketing Date, the entire 
indebtedness of the MOPPRS or (ii) certain restrictive covenants and Events 
of Default with respect to the MOPPRS, in each case upon compliance with 
certain conditions set forth therein, which provisions apply to the MOPPRS. 
Subject to the forgoing, prior to the Remarketing Date, neither the Trust nor 
any of its subsidiaries or affiliates shall defease, purchase or otherwise 
acquire, or enter into any agreement to defease, purchase or otherwise 
acquire, any of the MOPPRS prior to the remarketing thereof by the 
Remarketing Dealer. 

     8.   AMENDMENT AND MODIFICATION. The Indenture permits, with certain 
exceptions as therein provided, the amendment thereof and the modification of 
the rights and obligations of the Trust and the rights of the holders of the 
MOPPRS at any time by the Trust and the Trustee with the consent of the 
holders of not less than a majority of the aggregate principal amount of all 
MOPPRS at the time outstanding and affected thereby. The Indenture also 
contains 

                                         -10-




provisions permitting the holders of specified percentages in principal 
amount of the MOPPRS at the time outstanding, on behalf of the holders of all 
MOPPRS, to waive compliance by the Trust 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 MOPPRS shall 
be conclusive and binding upon such holder and upon all future holders of 
this MOPPRS and other MOPPRS issued upon the registration or transfer hereof 
or in exchange heretofore or in lieu hereof, whether or not notation of such 
consent or waiver is made upon this MOPPRS.

     9.   OBLIGATION TO PAY PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. No 
reference herein to the Indenture and no provision of this MOPPRS or of the 
Indenture shall alter or impair the obligation of the Trust, which is 
absolute and unconditional, to pay principal, premium, if any, and interest 
in respect of this MOPPRS at the times, places and rate or formula, and in 
the coin or currency, herein prescribed.

     10.  TRANSFER AND EXCHANGE. As provided in the Indenture and subject to 
certain limitations therein and herein set forth, the transfer of this MOPPRS 
is registrable in the Security Register of the Trust upon surrender of this 
MOPPRS for registration of transfer at the office or agency of the Trust in 
any place where the principal hereof and any premium or interest hereon are 
payable, duly endorsed by, or accompanied by a written instrument of transfer 
in form satisfactory to the Trust and the Security Registrar duly executed 
by, the holder hereof or by his attorney duly authorized in writing, and 
thereupon one or more new MOPPRS, of authorized denominations and for the 
same aggregate principal amount, will be issued to the designated transferee
