     Suite 800
     Rockville, Maryland 20852

                            SunTrust Bank-$50,000,000
      Revolving Credit Facility for Washington Real Estate Investment Trust

     Ladies and Gentlemen:

     Reference is made to the Amended and Restated Credit Agreement, dated as of
     August 26, 1999, but effective for all purposes as of July 25, 1999,
     between Washington Real Estate Investment Trust (the Borrower), SunTrust
     Bank, successor to Crestar Bank, as Agent, and SunTrust Bank (SunTrust),
     successor to Crestar Bank, and Wachovia Bank, National Association
     (Wachovia), successor to First Union National Bank (the Credit Agreement).
     Terms defined in the Credit Agreement shall have the same defined meanings
     when such terms are used herein.

     Wachovia has assigned all of its rights and obligations under the Credit
     Agreement to SunTrust, and SunTrust is now the sole Bank. SunTrust and the
     Borrower have agreed to modify the terms of the Credit Agreement.
     Accordingly, for valuable consideration, the receipt and sufficiency of
     which are acknowledged, the Agent, the Bank, the Borrower and WRIT LP agree
     that:

     1. The Termination Date is extended to July 25, 2005.

     2. The Commitment Schedule attached as Schedule 2.1 to the Credit Agreement
     is replaced by the Commitment Schedule attached as Schedule 2.1 to this
     Agreement.

     3. The Borrower shall no longer have the option to borrow Term Loans, and
     all references to a Term Loan or the Term Loans in the Credit Agreement are
     deleted.

     4. Section 2.4 of the Credit Agreement is amended to read in its entirety
     as follows:

                  "SECTION 2.4.             Prepayments.

                  (a) The Borrower shall have the right to prepay any Loans at
                  any time subject to the prepayment penalty described below;
                  provided, however, that each partial prepayment shall be in an
                  aggregate principal amount of not less than $1,000,000 or an
                  integral multiple thereof. No prepayment penalty will be
                  imposed for Prime Rate Loans, for a LIBOR Loan with an initial
                  Interest Period of three months or less or for a

<PAGE>

                  LIBOR Loan that is prepaid on the last day of the Interest
                  Period applicable thereto. The Borrower shall give the Agent
                  at least three Business Days' prior written notice of
                  prepayment (prompt written notice of which shall be given to
                  the Banks by the Agent) and in such notice specify the
                  prepayment date and the principal amount of each Loan to be
                  prepaid. Such notice of prepayment shall be irrevocable and
                  shall commit the Borrower to prepay in the amount stated
                  therein. All prepayments under this Section shall be
                  accompanied by accrued interest on the principal amount being
                  prepaid to the date of prepayment. Amounts prepaid shall be
                  available to be reborrowed from the Banks hereunder in
                  accordance with the terms of this Agreement.

                  (b) The prepayment penalty for a LIBOR Loan with an initial
                  Interest Period of more than three months that is prepaid on a
                  day other than the last day of the Interest Period applicable
                  thereto will be equal to the present value of the difference
                  between the amount of interest that would accrue on the
                  prepaid amount for the remaining term of the applicable
                  Interest Period at LIBOR that was in effect on the first day
                  of such Interest Period, and any lesser amount that would
                  accrue on the prepaid amount at LIBOR for an Interest Period
                  with the with a maturity most closely equal to, but not longer
                  than, the remaining term of the applicable Interest Period. To
                  determine such present value, the foregoing difference shall
                  be discounted to its present value at a discount rate equal to
                  the applicable LIBOR for such remaining Interest Period."

     5.  Section 5.2(a)(4) of the Credit Agreement is amended to read as
     follows:

                  "...(4) Liens on real estate assets securing Indebtedness
                  incurred in the ordinary course of the Borrower's business,
                  provided that at the time of the granting of such Lien and the
                  occurrence of such Indebtedness and after giving effect
                  thereto, no Default or Event of Default shall or would occur,
                  and the Borrower shall demonstrate to the reasonable
                  satisfaction of the Agent that the Borrower will be in
                  compliance on a pro forma basis with all of the terms and
                  provisions of the financial covenants set forth in Section
                  5.2(b)..."

     6.  The reference in Section 5.2(b)(2) of the Credit Agreement to
     "250,000,000" is amended to be "$450,000,000."

     7.  The reference in Section 5.2(b)(4) of the Credit Agreement to "fifteen
     percent (15%)" is amended to be thirty percent (30%)."

     8.  The reference in Section 6.1(e) to "$100,000" is amended to be
     "1,000,000."

     9.  Each reference in the Credit Agreement to "Crestar Bank" shall be
     amended to be a reference to SunTrust Bank.

     10. Notices in connection with the Credit shall be sent, in the case of the
     Borrower, to the attention of Sara L. Grootwassink, and in the case of the
     Agent, to the attention of Gregory T. Horstman.

<PAGE>

     11. Not later than July 25, 2002, the Borrower shall pay to the Agent for
     the account of SunTrust Bank an extension fee of $187,500.

     12. All of the obligations of the parties to the Credit Agreement, as
     amended hereby, and the other Loan Documents, are hereby ratified and
     confirmed. All references in the Loan Documents to the "Credit Agreement"
     shall henceforth be deemed to refer to the Credit Agreement as amended by
     this letter agreement.

     13. This letter agreement may be executed in any number of counterparts,
     all of which when taken together shall constitute one agreement, and any of
     the parties hereto may execute this letter agreement by signing any such
     counterpart; and

     14. All other terms and conditions of the Loan Documents remain unchanged
     and in full force and effect.

Item 6. Exhibit (10)(j)

                     WASHINGTON REAL ESTATE INVESTMENT TRUST

                               SHARE PURCHASE PLAN

1.     Purpose

       The Washington Real Estate Investment Trust Share Purchase Plan (the
"Plan") is intended to provide a means by which persons who serve as Trustees
of, but who are not employees of, Washington Real Estate Investment Trust (the
"Trust") (individually, the "Trustee" and collectively, the "Trustees"), may
increase their proprietary interest in the success and progress of the Trust as
the owners of the Trust's common shares (the "Common Shares").

2.     Administration and Consent to Plan Terms

       The Plan shall be administered by the Management Committee of the Trust
(the "Management Committee") which shall be composed of the Trust's President,
its Chief Financial Officer, and its Chief Accounting Officer. Each Trustee who
elects to participate in the Plan shall designate an Agent to perform the
functions and have the responsibilities assigned to the Agent with respect to
the purchase of Common Shares. The Management Committee shall have the right to
change the Agent appointed by a particular Trustee, but only with the prior
written consent of the affected Trustee.

       Notwithstanding any other provision to the contrary contained herein,
each Agent shall have all authority to determine the time of open market
purchases, the prices at which such open market purchases are made, the manner
of such open market purchases and the selection of brokers or dealers (which may
include the Agent) to make such purchases on behalf of the Trustee who
designated such Agent pursuant to this Paragraph 2.

       All costs and expenses incurred in purchasing Common Shares pursuant to
the Plan shall be paid by the Trust, including each Agent's reasonable brokerage
fee for the acquisition of such Common Shares.

       The consent of the Trust to the terms and conditions of the Plan shall be
evidenced by the signature of one of its authorized officers to this Plan. The
consent of each participating Trustee and his or her designated Agent to the
terms and conditions of the Plan shall be evidenced by their signatures or the
signatures of their authorized representatives to a Share Purchase Agreement
(the "Agreement"), the Form of which is attached hereto as Exhibit A.

3.     Eligibility

<PAGE>

       The only individuals eligible to participate in the Plan shall be the
Trustees of the Trust, provided, however, that a Trustee may not participate if
that Trustee would, immediately after a purchase of shares under the Plan, own
shares, and/or options to purchase shares, possessing five percent or more of
the total combined voting power or value of all classes of shares of the Trust
or of any subsidiary (applying the rules of Section 424(d) of the Internal
Revenue Code in determining share ownership).

4.     Shares

       The shares subject to purchase under the Plan shall be outstanding Common
Shares purchased in the open market, provided, however, that if the Trust
provides notice to the Agents at least three business days prior to the Purchase
Date, the shares shall be purchased from the Trust at a purchase price equal to
the average of the closing price of the shares, as reported by the American
Stock Exchange, or if the shares are no longer traded on the American Stock
Exchange, by such other exchange or market on which the shares are then traded,
for the five trading days immediately prior to the Purchase Date.

5.     Participation

       Each participating Trustee shall continue to participate until his or her
voluntary withdrawal from the Plan, resignation as a Trustee, non-reelection as
a Trustee, death or disability.

6.     Contributions

       From and after the date of participation, a portion of each participating
Trustee's compensation, even to the extent of his or her full compensation,
which would otherwise be paid in cash to such Trustee for serving as a member of
the Board of Trustees of the Trust (the "Board of Trustees") and for attending
regular and special meetings of the Board of Trustees and any applicable
committee meetings of the Board of Trustees (the "fees") shall be retained by
the Trust and allocated to an account on behalf of each such Trustee to be used
to purchase a specified number of Common Shares (the "Designated Number of
Shares") per month for such Trustee, as designated by such Trustee in his or her
Agreement and as described below.

7.     Purchase of Common Shares

       On the last trading day of each month (the "Purchase Date"), the Trust
shall transfer from each participating Trustee's account to his or her
designated Agent an amount equal to the estimated purchase price of the
Designated Number of Shares to be purchased in the open market with respect to
such month. In addition, the Trust shall transfer such additional amount to each
Agent as may be necessary to pay such Agent's commission with respect to the
acquisition of such Designated Number of Shares. The amount needed to pay each
such Agent's commission shall be paid directly by the Trust and shall not be
withdrawn from the Trustees' accounts. To the extent that the existing balance
in a Trustee's account is not sufficient to acquire the Designated Number of

                                       2

<PAGE>

Shares on his or her behalf, the full balance of the account shall be
transferred to his or her Agent to purchase such number of whole shares as is
possible given the then existing balance in such Trustee's account. His or her
Agent shall cause the proceeds received from the Trust to be applied to the open
market purchase of Common Shares on such Trustee's behalf.

       At any time prior to a Purchase Date, the Board of Trustees may terminate
the Plan without any obligation whatsoever to the Trustees, other than to refund
to them, without interest, any sum accumulated for them.

8.     Distributions from the Plan

       (a)    As soon as practicable after the end of each month, any residual
cash balance in a Trustee's account after the monthly transfer to his or her
Agent, described in Paragraph 7 above, shall be distributed to such Trustee.

       (b)    At such time as a covered individual shall cease to be a Trustee
for any reason other than death, any cash credited to his or her account under
this Plan shall be distributed to such individual as soon as practicable after
such termination of participation.

       (c)    In the event of a Trustee's death, any cash credited to his or her
account as of the end of the month in which such death occurred shall be applied
to the purchase of Common Shares under the terms of the Plan. After such shares
are purchased, all such shares and any remaining cash credited to such account
shall be distributed as soon as practicable thereafter (i) to the beneficiary
designated by such Trustee, or (ii) if no such designation shall have been made
or if a designated beneficiary does not survive such Trustee, to his or her
estate. Any designation of beneficiary (which may be any person, trust or other
entity) may be made, revoked or amended solely by the Trustee at any time, which
designation shall be effective upon receipt by the Management Committee.

9.     Amendment of the Plan

       The Board of Trustees may from time to time alter, amend, suspend or
discontinue the Plan except that no alteration or amendment shall be made more
than once in every twelve-month period with respect to the dates on which Common
Shares shall be purchased for each participating Trustee's account.

10.    Miscellaneous

       (a)    Nothing in the Plan shall be deemed to create any obligation on
the part of the Board of Trustees to nominate any of the Trustees covered by
this Plan for reelection by the Trust's shareholders.

                                       3

<PAGE>

       (b)    The Plan and all determinations made and actions taken pursuant to
the Plan shall be interpreted, constructed, and enforced in accordance with the
laws of the State of Maryland, including any questions of choice of law.

<PAGE>

11.    Effective Date

       The effective date of the Plan shall be October 28, 1997.

       IN WITNESS WHEREOF, the Trust, by its duly authorized officer, has
executed the Plan as of October 28, 1997.

                            Share Purchase Agreement

       This Agreement made this ____ day of _______, 199_, by and between
Washington Real Estate Investment Trust (the "Trust"), __________________ (the
"Trustee"), and ______________________________ (the "Agent").

       1.     The Trustee hereby designates ___________________________________
              as his/her Agent, pursuant to the terms and provisions of the
              Washington Real Estate Investment Trust Share Purchase Plan (the
              "Plan"), to perform the functions and have the responsibilities
              assigned to the Agent under the Plan with respect to the purchase
              of Common Shares on the Trustee's behalf. Said Agent shall have
              all authority to determine the time of open market purchases, the
              prices at which such open market purchases shall be made, the
              manner of such open market purchases, and the selection of brokers
              or dealers (which may include the Agent) to make such purchases on
              behalf of the Trustee.

       2.     The Trustee hereby elects, pursuant to the terms and provisions of
              the Plan, to use a portion of his/her compensation, even to the
              extent of his/her full compensation, which would otherwise be paid
              in cash to him/her for serving as a member of the Board of
              Trustees of the Trust (the "Board of Trustees") and for attending
              regular and special meetings of the Board of Trustees and any
              applicable committee meetings of the Board of Trustees to
              purchase, through his/her designated Agent, shares of the Trust's
              common shares (the "Common Shares").

       3.     The number of Common Shares which will be purchased each month
              shall be equal to the lesser of (i) ____________________ shares or
              (ii) such number of whole shares as may then be purchased through
              the existing balance in the Trustee's account under the Plan.

       4.     The purchase price for the Common Shares shall be remitted by the
              Trust to the Agent from the Trustee's account under the Plan each
              month pursuant to instructions from the Agent. All other costs and
              expenses incurred in purchasing Common Shares pursuant to the Plan
              shall be paid by the Trust, including Agent's reasonable brokerage
              fee for the acquisition of such Common Shares on the Trustee's
              behalf.

              they have received a copy of the Plan and agree to be bound by the
              terms and provisions of the Plan.
