              ---------------------------------------------------

                $120,000,000 Unsecured Revolving Line of Credit


          THIS FIRST AMENDED AND RESTATED REVOLVING LOAN AGREEMENT, dated as of
May 16, 2000 (the "Agreement"), is between Essex Portfolio, L.P., a California
limited partnership ("Borrower"); Essex Property Trust, Inc., a Maryland
corporation operating as a real estate investment trust ("Guarantor"); Bank of
America, N.A. as administrative agent for the Lenders as that term is defined
below ("Administrative Agent" or "Bank"); Banc of America Securities LLC, a
Delaware limited liability company, as sole lead arranger and sole book manager
(the "Arranger"); and, with Union Bank of California, N.A. and Bank One, N.A.,
as co-syndication agents (the "Co-Syndication Agents"); and Bank and the several
additional financial institutions from time to time a party to this Agreement
(collectively, the "Lenders" and individually a "Lender"; and as that terms is
defined below).

                              FACTUAL BACKGROUND
                              ------------------

          A.   Bank has previously made available to Borrower a revolving line
of credit subject to the conditions set forth in that certain Revolving Loan
Agreement dated as of May 11, 1998 (the "Existing Agreement") to provide funds
for the interim financing for acquisitions of residential apartment properties,
for letters of credit, for general working capital, and for other needs (the
"Line of Credit Loan") excluding the repurchase of the common stock of
Guarantor.

          B.   The Line of Credit Loan is evidenced by a promissory note (the
"Existing Note") of even date with the Existing Agreement.

          C.   Guarantor is the general partner of Borrower. Bank was only
willing to make the Line of Credit Loan if Guarantor would guaranty repayment of
the obligations of Borrower under the terms of the Existing Agreement.

          D.   Guarantor made such a guaranty (the "Guaranty") to Bank as
provided in the Existing Agreement.

          E.   The parties hereto would like to amend the Existing Agreement to
make certain changes in terms relating to the Line of Credit Loan. Among those
changes, the parties would like to provide that Bank as Swing Line Lender (as
that term is defined in Section 1 of this Agreement) may make available to
Borrower a so-called swing line of credit so that when Borrower makes a request
for funds, Bank may, at its discretion, immediately advance such amounts as a
swing loan, and to further amend the Existing Agreement to provide that such
amounts will be repaid to Bank as Swing Line Lender at the time of the advance
under the Line of Credit Loan within three (3) Business Days

                                      -1-
<PAGE>

with the Borrower's agreement that such repayment will be made with advances
from the Line of Credit Loan.

          F.   Guarantor would like to consent to such an amendment of the
Existing Agreement and confirm its obligations under and renew the Guaranty.

          Borrower would like to execute a first amended and restated note to
replace the Existing Note ("First Amended and Restated Note").

          In conjunction with the swing line, Borrower would like to execute a
swing line note (the "Swing Line Note") to evidence any and all swing loans.

          This Agreement, the First Amended and Restated Note, the Swing Line
Note, the Guaranty and any modifications thereto, and all other documents
evidencing, securing or otherwise pertaining to the Loan are referred to herein
each as a "Loan Document," and collectively, as the "Loan Documents."

     ----------------------

     2.1  Line of Credit; Option to Increase Line of Credit.
          -------------------------------------------------

          (a)    During the Availability Period, Administrative Agent, for
Lenders, will provide a revolving line of credit (the "Line of Credit") to
Borrower to (i) make advances, and (ii) issue standby letters of credit (each,,
a "Letter of Credit" for Borrower's account.

                                      -9-
<PAGE>

          (b)  The maximum amount of the Line of Credit committed by Lenders
is One Hundred Twenty Million Dollars ($120,000,000) (the "Commitment").
Administrative Agent shall disburse funds under the Line of Credit in such
amounts as Borrower may request from time to time hereunder, but in no case
shall the sum of the total principal amount outstanding under the terms of this
Agreement (including the aggregate amount owing to Lenders in connection with
drawn and unreimbursed Letters of Credit), plus the aggregate amount of
outstanding and undrawn Letters of Credit (the "Total Amount Outstanding"),
exceed an aggregate principal amount (the "Available Amount") equal to the
smallest of the following, tested at the beginning of each calendar quarter and
at the time of each draw hereunder:

     (x)  an amount equal to fifty percent (50%) of the Unencumbered Asset
      -
          Pool Value of the Unencumbered Asset Pool Property; or

     (y)  an amount equal to one hundred percent (100%) of the Mortgage Value
      -
          of the Unencumbered Asset Pool Property; or

     (z)  an amount equal to the Commitment.
      -

          (c)  If Administrative Agent at any time should determine that the
Total Amount Outstanding exceeds the Available Amount, Administrative Agent may
make written demand on Borrower at Administrative Agent's option, to post cash
or other collateral satisfactory to Administrative Agent in its sole discretion,
or to repay principal hereunder, or both, in an amount sufficient in
Administrative Agent's reasonable judgment to cause the Total Amount Outstanding
to be equal to or less than the Available Amount. Borrower shall make any such
payment of principal or post any such collateral within thirty (30) days after
Administrative Agent's demand and direction to Borrower.

          (d)  This is a revolving line of credit. During the Availability
Period, Borrower may repay and reborrow principal amounts.

          (e)  Each advance must be for at least Five Hundred Thousand Dollars
($500,000), or for the amount of the remaining Available Amount, if less.

          (f)  The issuance of a Letter of Credit pursuant to Section 2.4 hereof
shall be considered an advance for all purposes hereunder, except that, absent
an express written agreement to the contrary, any drawn Letter of Credit shall
be repaid by Borrower to Administrative Agent on demand.

          (g)  At any time during the Availability Period, including any
extension thereof by Administrative Agent, Borrower will have an option to
increase the Line of Credit by up to Thirty Million Dollars ($30,000,000) (the
"Commitment Increase"). The Commitment Increase will be made by Administrative
Agent subject to the satisfaction of the following conditions precedent: (i)
Borrower shall have given ninety (90) days prior written notice to
Administrative Agent of its exercise of such option for the Commitment

                                     -10-
<PAGE>

Increase, Borrower shall have paid Administrative Agent, for the benefit of
Lenders a fee to be determined, (ii) Administrative Agent shall have received
such additional commitments from Lenders (who may make or withhold such
commitments in their sole discretion) as is necessary to fund the Line of Credit
Increase, and (iii) no Event of Default, or event that with the passage of time
could become an Event of Default, shall have occurred and be continuing.

     2.2  Availability Period; Extension of Availability Period.
          -----------------------------------------------------

          (a)  The Line of Credit is available between the date of this
Agreement (the "Effective Date") through the end of the first Business Day two
years from the Effective Date (the "Expiration Date"). The period from the
Effective Date to the Expiration Date shall be the "Availability Period." If
there is an Event of Default (as defined in Section 9.1 below) then in addition
to Lenders' other remedies, Administrative Agent may terminate the Availability
Period and require Borrower to immediately (i) repay amounts outstanding under
the Loan, and (ii) provide cash collateral for repayment of any outstanding
Letter of Credit. If Borrower has violated any covenant or agreement hereunder
and the applicable cure period has not yet expired, then it is within
Administrative Agent's sole and absolute discretion whether to continue to
provide extensions of credit to Borrower hereunder until such time as such
violation is cured.

          (b)  Borrower may extend the Availability Period for one year upon
satisfaction of the following conditions precedent: (i) Borrower shall have
given written notice to Administrative Agent of such request no more than ninety
(90) and no less that sixty (60) days prior to the second anniversary of the
Effective Date, (ii) Borrower shall have paid Administrative Agent for the
benefit of Lenders a fee equal to twenty-five one-hundredths percent (.25%) of
the Commitment, and (iii) no Event of Default, or event that with the passage of
time could become an Event of Default, shall have occurred and be continuing.
If, upon such request by Borrower, Administrative Agent reasonably determines
that Borrower has satisfied these conditions precedent, the Expiration Date
shall then be extended by one year, the new date of expiration shall be the
      ----
"Expiration Date", and the Availability Period as so extended shall become the
"Availability Period".

          (c)  Borrower may cancel all or any portion of the Commitment by the
delivery to Administrative Agent of a notice of cancellation within the
applicable time periods and minimum amounts set forth, if any, in the Loan
Documents for the repayment of any amounts that are outstanding or, if there are
no amounts outstanding at such time, upon at least five (5) business days notice
to Administrative Agent, whereupon, in either event, such part of the Commitment
so designated by Borrower shall terminate on the date set forth in such notice
of cancellation, and, if there are any Loans then outstanding in excess of the
Commitment after giving effect to such termination, Borrower shall prepay such
Loans outstanding on such date in accordance with the requirements of the Loan
Documents.

     2.4  Letters of Credit.
          -----------------

          (a)  From time to time during the Availability Period, Administrative
Agent, for Lenders, shall at the request of Borrower, issue Letters of Credit in
the Administrative Agent's standard form under the terms of a Letter of Credit
Agreement in the form of Exhibit "B", for the account of Borrower, a Permitted
                         -----------
Owner or an entity controlled by a Permitted Owner, for any purpose directly
relating to Borrower's continuing operations, upon at least five (5) Business
Days prior written notice from Borrower; provided, however, that at no time
shall any Letter of Credit have an expiration date that exceeds the earlier in
time of (i) one year from the date the Letter of Credit is issued, and (ii) a
date that is sixty (60) days prior to the Expiration Date as it may be extended;
provided, however, that at no time shall the undrawn and the drawn and
unreimbursed amount of all Letters of Credit exceed the least of (i) Twenty
Million Dollars ($20,000,000), (ii) the maximum Commitment amount, and (iii) the
Available Amount minus the Total Amount Outstanding (the "Letter of Credit
                 -----
Cap"). As provided above, a Letter of Credit may be issued for the benefit of a
Permitted Owner, or an entity controlled by a Permitted Owner, but any such
Letter of Credit shall be the responsibility of and shall create obligations of
Borrower and any guarantor, including but not limited to Guarantor.

          (b)  Each Letter of Credit issued hereunder (including any supplement,
modification, amendment, renewal or extension thereof) shall be issued pursuant
to the terms and conditions of a standard form Application and Agreement for
Letter(s) of Credit ("Letter of Credit Agreement") in a form substantially the
same as that attached hereto as Exhibit "B" executed by Borrower; and each
                                -----------
Letter of Credit shall be in form and substance and for the purposes provided in
this Agreement. Pursuant to the terms and conditions of the standard form of
Letter of Credit Agreement, any drawings under a Letter of Credit shall be
repaid by Borrower to Administrative Agent for Lenders on demand; and the Letter
of Credit Agreement will set forth all of the terms and conditions regarding the
issuance of a Letter of Credit and any draws thereunder.

                                     -12-
<PAGE>

          (c)    The Letter of Credit Agreement shall set forth the rate of
interest on any draws thereunder. Any amount drawn shall be payable by Borrower
no later than the next Business Day after the date on which the amount is drawn.

          (d)    [Reserved.]

          (e)    If at any time there are Letters of Credit outstanding and the
Loan is canceled or expires by its terms and an extended term is not made
available to Borrower by Administrative Agent or in accordance with the terms of
this Agreement, or an Event of Default (as hereinafter defined) occurs and is
continuing, Borrower shall provide the Lender or Lenders issuing the Letters of
Credit with cash collateral in an amount at least equal to the aggregate amount
of all Letters of Credit outstanding, or another form of collateral acceptable
to such Lenders in their sole and absolute discretion. Borrower agrees to
execute or cause the execution of all documents reasonably required by such
Lenders at Borrower's sole cost and expense in connection with Borrower's
delivery of collateral hereunder. Lender or Lenders shall retain a security
interest in such collateral until the earlier occurrence of (a) a date fifteen
(15) days after the expiration of any outstanding Letter of Credit, provided
that no further extensions shall have been granted, or (b) the cancellation of
any outstanding Letter of Credit by the respective beneficiaries, provided that
written notice of such cancellation has been received by Lender or Lenders or
the original Letter of Credit is returned to such Lender or Lenders. In such an
event, the amount of collateral retained by Lender or Lenders shall be adjusted
as appropriate to reflect such expiration or cancellation, as the case may be.

          (f)    Borrower shall pay Administrative Agent, for the benefit of
Lenders, an annual fee for each Letter of Credit. The annual fee shall be equal
to the Applicable LIBOR Rate Margin on the date of issuance of the Letter of
Credit. The fee shall be paid in equal quarterly installments beginning on the
date of issuance of each Letter of Credit and continuing on the first day of
each quarter thereafter during which the Letter of Credit remains outstanding or
has been drawn and remains unreimbursed. Borrower shall also pay to
Administrative Agent, a fronting fee (the "Fronting Fee") at the time each
Letter of Credit is issued. The Fronting Fee shall be an amount equal to the
greater of (i) twelve and one-half (12.5) basis points of the face amount of the
Letter of Credit, or (ii) Seven Hundred and Fifty Dollars ($750).

the Line of Credit Loan, cause it to exceed its pro rata share as a Lender of
the maximum amount of the Commitment. Within the limits of the Swing Line
Availability, Borrower may borrow under this SubSection 2.5.1 at any time until
the Expiration Date or, the extended Expiration Date (or any other date on which
the Loan is due), repay same pursuant to Subsections 2.5.3 or 2.5.4 and reborrow
pursuant to this SubSection 2.5.1 at any time until the Expiration Date or, the
extended Expiration Date (or any other date on which the Loan is due). Each
Swing Loan must be for at least Five Hundred Thousand Dollars ($500,000), or for
the remaining Swing Line Availability if less. Notwithstanding any contrary
provision of this Section 2.5, the Swing Line Lender shall make Swing Loans only
in its discretion and shall not at any time be obligated to make any Swing Loan.

          2.5.2  Each Swing Loan outstanding under the Swing Line shall accrue
interest at a rate per annum set out in the Swing Line Note, which interest
shall be equal to the Administrative Agent's Prime Rate plus the Applicable
Prime Rate Margin. The Administrative Agent's Prime Rate is the rate of interest
most recently announced by the Bank, as agent, at its principal office located
in Charlotte, North Carolina, as its "Prime Rate." The interest on each Swing
Loan outstanding under the Swing Line shall be payable in arrears as provided in
the Swing Line Note and on the due date for Swing Loans set forth in SubSection
2.5.3, and shall be payable to Administrative Agent for the account of the Swing
Line Lender; provided that, notwithstanding any other provision of this
             --------
Agreement, each Swing Loan shall bear interest for a minimum of one (1) day.
Such interest shall be calculated on the basis of a three hundred sixty (360)
day year and actual days elapsed, which results in higher interest than if a
three hundred sixty-five (365) day year were used.

          2.5.3  The principal outstanding under the Swing Line shall be due and
payable:

                 (1)  at or before 10:00 a.m., San Francisco time, by the end of
the third Business Day immediately following any date on which a Swing Loan is
made under the Swing Line; and

                 (2)  in any event, on the Expiration Date or, if the Expiration
Date is expressly extended under Section 2.2(b), the extended Expiration Date,
or on any other date that the Loan is due;

provided that, if no Event of Default has occurred and remains uncured, and
--------
Borrower is permitted to borrow under the terms of this Agreement (the Available
Amount being determined for such purpose without giving effect to any reduction
thereof occasioned by

                                     -14-
<PAGE>

such Swing Loans due and payable) at the time such Swing Loans are due, then
Borrower shall be deemed to have submitted a Borrowing Notice in an amount
necessary to repay such Swing Loans on their due date, and any provisions of
this Agreement concerning (i) the minimum principal amounts required for
borrowings and (ii) the funding of requested borrowings as Swing Loans shall not
apply to Loans made pursuant to this SubSection 2.5.3.

          2.5.4  Borrower may, from time to time on any Business Day, make a
voluntary prepayment, in whole or in part, of the outstanding principal amount
of any Swing Loans, without incurring any premium or penalty; provided that:
                                                              --------
                 (1)  each such voluntary prepayment shall require prior written
notice given to Administrative Agent and Swing Line Lender no later than 10:00
a.m., San Francisco time, on the day on which Borrower intends to make a
voluntary prepayment, and

                 (2)  each such voluntary prepayment shall be in a minimum
amount of Five Hundred Thousand Dollars ($500,000) (or, if less, the aggregate
outstanding principal amount of all Swing Loans then outstanding).

          2.5.5  At any time during the continuance of an Event of Default, the
Swing Line Lender may, without Borrower's consent, upon one (1) Business Day's
notice to Borrower, terminate the Swing Line and cause a Loan to be made in an
aggregate amount equal to the amount of principal and interest outstanding under
the Swing Line (the Available Amount being determined for such purpose without
giving effect to any reduction thereof occasioned by such Swing Loans), and the
conditions precedent set forth in this Agreement, and any requirement that a
borrowing be funded as a Swing Loan, shall not apply to such Line of Credit
Loan. The proceeds of such Line of Credit Loan shall be paid to the Swing Line
Lender to retire the outstanding principal and interest owing under the Swing
Line.

          2.5.6  The Swing Loans made by the Swing Line Lender shall be
evidenced by a Swing Line Note payable to the order of the Swing Line Lender in
the amount of Twenty-Five Million Dollars ($25,000,000).

          2.5.7  Each Lender shall, upon the request of the Swing Line Lender
purchase its pro rata share of the Swing Loans then outstanding within three
days after the advance of any such Swing Loan.

     2.6  Survival.
          --------

          The agreements and obligations of Borrower in this Article 2 shall
survive the payment and performance of all other obligations.

     ----

     3.1  Facility Fee.
          ------------

          Borrower shall pay Administrative Agent, for the benefit of Lenders,
an annual fee (the "Facility Fee") equal to the Per Annum Facility Fee from time
to time determined by reference to the grid appearing in the definition of the
Applicable Margin multiplied by the amount of the Commitment.  Borrower shall
pay Administrative Agent, for the benefit of Lenders, such Facility Fee in
arrears quarterly in equal installments during the Availability Period.

Notice") and made a part hereof, or by another means acceptable to
Administrative Agent. Unless Borrower's Borrowing Notice expressly requests
otherwise or is in an amount in excess of the Swing Line Availability or is for
the issuance of a Letter of a Credit, each requested borrowing shall initially
be funded as a Swing Loan, and shall be subject to the provisions of Section
2.5. Borrower hereby authorizes John D. Eudy, Keith R. Guericke, Michael J.
Schall, Mark J. Mikl or Jordan E. Ritter to sign all Borrowing Notices and other

     4.2  Disbursements and Payments.
          --------------------------

          Each disbursement by Administrative Agent and each payment by Borrower
will be:

                                     -16-
<PAGE>

          (a)  made at Administrative Agent's branch (or other location)
selected by Administrative Agent in its reasonable discretion from time to time;

          (b)  made for the account of Administrative Agent's branch selected by
Administrative Agent in its reasonable discretion from time to time;

          (c)  made in immediately available funds, or such other type of funds
selected by Administrative Agent;

Administrative Agent may, at its discretion, require Borrower to sign one
or more promissory notes.

     4.3  Telefax Authorization.
          ----------------------

          (a)  Administrative Agent may honor telefax instructions from John D.
Eudy, Keith Guericke, Michael J. Schall, Mark J. Mikl or Jordan E. Ritter for
advances or repayments or for the designation of optional interest rates
described in the Note given by any one of the individuals authorized to sign
loan agreements on behalf of Borrower, or any other individual designated by any
one of such authorized signers.

          (b)  Advances and repayments will be either (i) deposited in and
repayments will be withdrawn from Borrower's account number 14228-02371 or such
other of Borrower's accounts with Administrative Agent as designated in writing
by Borrower, or (ii) by wire transfer at Borrower's written direction, which
written direction may be telefaxed as set forth herein.

          (c)  Borrower will provide written confirmation to Administrative
Agent of any telefax instructions within five (5) days. If there is a
discrepancy and Administrative Agent has already acted on the instructions, the
telefax instructions will prevail over the written confirmation.

          (d)  Borrower indemnifies and excuses Administrative Agent (including
its officers, employees, and agents) from all liability, loss, and costs in
connection with any act resulting from telefax instructions, given under this
Section 4.3, it reasonably believes are made by any individual authorized by
Borrower to give such instructions, except to the extent such liability, loss,
or cost results directly from Administrative Agent's gross negligence or willful
misconduct. This indemnity and excuse will survive this Agreement's termination.

     4.4  Taxes. If any payments to Administrative Agent under this Agreement
          -----
are made from outside the United States, Borrower will not deduct any foreign
taxes from any payments it makes to Administrative Agent. If any such taxes are
imposed on any payments made by Borrower (including payments under this
Subsection), Borrower will pay the taxes and will also pay to Administrative
Agent, at the time interest is paid, any additional amount which Administrative
Agent specifies as necessary to preserve the

                                     -17-
<PAGE>

after-tax yield Administrative Agent or any Lender would have received if such
taxes had not been imposed. Borrower will confirm that it has paid the taxes by
giving Administrative Agent official tax receipts (or notarized copies) within
thirty (30) days after the due date.

     4.5  Additional Costs. Upon sixty (60) days' notice, Borrower will pay
          ----------------
Administrative Agent, for Administrative Agent's or any Lender's costs or losses
related to this Agreement arising from any statute or regulation, or any request
or requirement of a regulatory agency, which is applicable to all national banks
or a class of all national banks. The costs and losses will be allocated to the
loan in a manner determined by Administrative Agent, using any reasonable
method. The costs include the following:

          (a)  any reserve or deposit requirements; and

          (b)  any capital requirements relating to Administrative Agent's or
any Lender's assets and commitments for credit.

5.   UNENCUMBERED ASSET POOL.
     ------------------------

     5.1  Unencumbered Asset Pool and Unencumbered Asset Pool Property Defined.
          ---------------------------------------------------------------------

          The "Unencumbered Asset Pool" or the "UAP" shall mean the property
listed on Exhibit "D", plus any and all of the real and personal property added
          -----------
to the Unencumbered Asset Pool under the terms of Section 5.2 below, minus any
and all of the real and personal property removed from the Unencumbered Asset
Pool under the terms of Section 5.3 below. "Unencumbered Asset Pool Property"
shall mean the real and personal property that makes up the Unencumbered Asset
Pool at any time.

     5.2  Additions of Property to the Unencumbered Asset Pool.
          -----------------------------------------------------

          (a)  Borrower may from time to time request Administrative Agent to
add a new property ("the Nominated Property") to the Unencumbered Asset Pool.
Properties in the UAP must satisfy and continue to satisfy, at all times during
the term of the Line of Credit Loan, each of the following criteria:

               (1)  All properties shall be owned in fee simple interest by
Borrower, or by a Permitted Owner provided that such Permitted Owner shall
provide to Administrative Agent its formation documents and a guaranty in
substantially the same form as the Payment Guaranty (Revolving Loan) executed by
Guarantor of even date with this Agreement;

               (2)  all properties shall be operated as residential apartments,
with no more than fifteen percent (15%) of revenue generated by retail
businesses;

                                     -18-
<PAGE>

               (3)  there shall be a minimum occupancy of eighty percent (80%)
in individual properties, and an aggregate occupancy of ninety percent (90%) for
the UAP;

               (4)  a Phase I environmental site assessment prepared within one
(1) year of its delivery in form and substance reasonably acceptable to
Administrative Agent shall have been completed and shall not have disclosed the
presence of any material toxic or hazardous substances on any property, except
for cleaning, pool and other chemicals typically located on residential
properties that are otherwise consistent with all applicable laws; and

               (5)  all properties shall be free of all liens, encumbrances and
negative pledges, except for the following permitted liens ("Permitted Liens"):
(a) liens for taxes, assessments or governmental charges or levies to the extent
that the Borrower or the Permitted Owner is not yet required to pay the amount
secured thereby; and (b) liens imposed by law, such as carrier's, warehouseman's
, mechanic's, materialman's and other similar liens, arising in the ordinary
course of business in respect of obligations that are not overdue or are being
actively contested in good faith by appropriate proceedings, as long as the
Borrower or the Permitted Owner has established and maintained adequate reserves
for the payment of the same and, by reason of nonpayment, no property of the
Borrower or the Permitted Owner is in danger of being lost or forfeited; and
easements; covenants, conditions and restrictions; reciprocal easement and
access agreements and similar agreements relating to ownership and operation.

Properties that meet the UAP criteria above will automatically be included in
the UAP, provided Borrower has a BBB-/Baa3 or better credit rating from a Rating
Agency.  If Borrower's credit rating is less than BBB-/Baa3, properties will be
added to the UAP at the sole and absolute discretion of the Required Lenders.

Notwithstanding the criteria listed above, two properties shall be included as
part of the UAP even though they do not meet the criteria listed above, with the
following qualifications.  That property commonly known as Marina Cove shall be
included in the UAP even though a portion of the property has been acquired by
ground lease and not by fee simple; that property must meet all of the other
criteria listed above.  That property commonly known as Windsor Terrace shall be
included in the UAP even though one (1) unit in that property is owned by a
third party; that property must meet all of the other criteria listed above but
the Net Operating Income for the units owned by third parties shall not be used
in the calculations for determining any amounts referred to in this Agreement.

          (b)  Borrower may from time to time elect to remove an Unencumbered
Asset Pool Property from the Unencumbered Asset Pool. Borrower shall make such
an election by giving Administrative Agent notice in writing, setting forth the
identity of the Unencumbered Asset Pool Property and the requested date of
removal no less than thirty (30) days before the requested date of removal. With
such notice, Borrower shall also

                                     -19-
<PAGE>

deliver a compliance certificate of Borrower substantially similar to the form
of Exhibit "E" signed and certified by an authorized financial officer of
   -----------
Borrower (i) setting forth the information and computations (in sufficient
detail) to determine the Gross Asset Value after such removal and to establish
that Borrower will be in compliance with all financial covenants set forth in
this Agreement following such removal, (ii) stating specifically that the Total
Amount Outstanding after such removal will be less than or equal to the
Available Amount, and (iii) setting forth whether there exists or to the best of
Borrower's knowledge as of the date of such removal there will exist, any
default under this Agreement and, if any such default exists, specifying the
nature thereof and the action Borrower is taking and proposes to take with
respect thereto. At the time of any such removal, Borrower shall pay
Administrative Agent all reasonable attorneys' fees (including fees for in-house
counsel) incurred by Administrative Agent in connection with removing the
property from the Unencumbered Asset Pool and shall make any payments to
continue compliance with the terms of this Agreement, including but not limited
to those relating to the requirement that the Total Amount Outstanding not
exceed the Available Amount, necessary as a result of the requested removal.
Borrower may not remove the Unencumbered Asset Pool Property until it has
complied with the terms of this SubSection 5.2.

          (c)  Administrative Agent may, at its option, remove any property from
the Unencumbered Asset Pool if it determines in its sole discretion that the
property no longer meets the criteria of the Unencumbered Asset Pool as required
by Section 5 of this Agreement, provided that Administrative Agent first gives
Borrower written notice that the property no longer meets the criteria of the
Unencumbered Asset Pool as required by Section 5 of this Agreement, together
with the reason or reasons why it does not, and gives Borrower thirty (30) days
after receipt of such notice to cure the defect. At the time of any such
removal, Borrower shall pay Administrative Agent all reasonable attorneys' fees
(including fees for in-house counsel) incurred by Administrative Agent in
connection with removing the property from the Unencumbered Asset Pool, and
shall make any payments to continue compliance with the terms of this Agreement,
including but not limited to those relating to the requirement that the Total
Amount Outstanding not exceed the Available Amount, necessary as a result of the
requested removal. If the Unencumbered Asset Pool as a whole fails to meet any
of the criteria set out in Section 5 of this Agreement, and any one of two or
more properties might be removed to maintain compliance of the Unencumbered
Asset Pool as a whole with the criteria of the Unencumbered Asset Pool as
required by Section 5 of this Agreement, then Borrower shall select the property
or properties to be removed, provided that if it does not do so within ten (10)
days of written request to do so from Administrative Agent, then Administrative
Agent may in its sole discretion select the property or properties to remove and
so remove them.

----------

          (b)  A title insurance policy insuring Borrower's or its subsidiaries'

to the Administrative Agent for any property now in the Unencumbered Asset Pool,
as listed on Exhibit "D" attached hereto.
             ----------

          (c)  A current rent roll; and

          (d)  An operating statement, which shall include a detailed analysis

(4) quarters shall be valued by annualizing the Net Operating Income for the
most recent consecutive whole quarters that the properties have been owned by
Permitted Owners

                                     -21-
<PAGE>

(i.e., properties owned for two (2) consecutive whole quarters shall annualize
Net Operating Income by multiplying by a factor of (2) two) less $250 per unit
reserve, capitalized at the Capitalization Rate; and

          (c)  properties owned less than one (1) quarter, shall be valued at
seventy-five percent (75%) of their acquisition cost.

     5.5  Unencumbered Asset Pool Mortgage Value.
          ---------------------------------------

          The Unencumbered Asset Pool Mortgage Value (herein referred to
sometimes as, the "Mortgage Value") will be the maximum mortgage amount
supportable by the Unencumbered Asset Pool at a 1.75:1.0 Debt Service Coverage
Ratio plus thirty-seven and one-half percent (37.5%) of acquisition cost for
properties held for less than one (1) calendar quarter. Debt Service Coverage
Ratio shall be calculated using Net Operating Income for the Unencumbered Asset
Pool properties for the four (4) most recent consecutive full calendar quarters
(or on an annualized basis if the property has been held for less than four (4)
calendar quarters), less a $250 per unit capital expense reserve, divided by a
calculated debt service payment based on the greater of: (i) a nine and forty-
six one-hundredths percent (9.46%) mortgage constant (8.25%; 25 years) or (ii)
the seven year U.S. treasury rate plus one and seventy-five one-hundredths

The arbitrator(s) shall give effect to statutes of limitation in determining any
claim. Any controversy concerning whether an issue is arbitrable shall be
determined by the arbitrator(s). Judgment upon the arbitration award may be
entered into any court having jurisdiction. The institution and maintenance of
an action for judicial relief or pursuit of a provisional or ancillary remedy
shall not constitute a waiver of the right of any party, including the
plaintiff, to submit the controversy or claim to arbitration if any other party
contests such action for judicial relief.

     10.2  Judicial Reference. Subject to SubSection 10.1 above, in any judicial
           ------------------

Documents or based on or arising from an alleged tort, all decisions of fact and
law shall at the request of any party be referred to a referee in accordance
with California Code of Civil Procedure Sections 638 et seq. The parties shall
designate to the court a referee or referees selected under the auspices of the
AAA in the same manner as arbitrators are selected in AAA-sponsored proceedings.
The presiding referee of the panel, or the referee if there is a single referee,
shall be an active attorney or retired judge. Judgment upon the award rendered
by such referee(s) shall be entered in the court in which such proceeding was
commenced in accordance with California Code of Civil Procedure Sections 644 and
645.

     10.3  Provisional Remedies; Self-Help. No provision of this Agreement shall
           -------------------------------
limit the right of any party to this Agreement to exercise self-help remedies
such as setoff, or obtaining provisional or ancillary remedies from a court of
competent jurisdiction before, after, or during the pendency of any arbitration
or other proceeding. The exercise of a remedy does not waive the right of either
party to resort to arbitration or reference.

11.  MISCELLANEOUS PROVISIONS.
     ------------------------

     11.1  No Waiver; Consents.
           --------------------

           No alleged waiver by Administrative Agent or any Lender shall be
effective unless in writing, and no waiver shall be construed as a continuing
waiver.  No waiver shall be implied from any delay or failure by Administrative
Agent or any Lender to take action on account of any default of Borrower.
Consent by Administrative Agent or any Lender to any act or omission by Borrower
shall not be construed as a consent to any other or subsequent act or omission.

addresses or numbers may be changed by either party by written notice to the
other party.

     11.4  Attorneys' Fees.
           ----------------

           If any lawsuit, reference or arbitration is commenced which arises

including any alleged tort action, regardless of which party commences the
action, the prevailing party shall be entitled to recover from each other party
such sums as the court, referee or arbitrator may adjudge to be reasonable
attorneys' fees in the action or proceeding, in addition to costs and expenses
otherwise allowed by law. Any such attorneys' fees incurred by either party in
enforcing a judgment in its favor under this Agreement shall be recoverable
separately from and in addition to any other amount included in such judgment,
and such attorneys' fees obligation is intended to be severable from the other
provisions of this Agreement and to survive and not be merged into any such
judgment. In all other situations, including any bankruptcy or other voluntary
or involuntary proceeding, in or out of court, for the adjustment of debtor-
creditor relationships, Borrower agrees to pay all of Administrative Agent's
costs and expenses, including attorneys' fees, which may be incurred in any

institutions shall be acceptable to the Borrower (such acceptance not to be
unreasonably withheld.) Each Lender will be authorized to disseminate any
information it obtains pertaining to the Loan, including, without limitation,

Borrower, to any assignee or participant or prospective assignee or prospective
participant, to any of the Lenders' affiliates, any regulatory body having
jurisdiction over any Lender and to any other parties as necessary or
appropriate in any of the Lenders' reasonable judgment. Borrower agrees to
actively assist the Arranger in syndication of the Loan. To assist the Arranger
in its syndication efforts, the Borrower shall, at the request of the Arranger:
(1) provide and cause its advisors to provide the Arranger and any Lender that
becomes party to this Agreement as a successor in interest to a Lender, upon
request, with all information reasonably deemed necessary by the Arranger to

transfer the Loan to any other persons or entities without the consent of or
notice to Borrower. Without the consent of or notice to Borrower, Administrative
Agent and Lenders may disclose to any prospective purchaser of any securities
issued by Administrative Agent or Lenders, and to any prospective or actual
purchaser of any interest in the Loan or any other loans made by Lenders to
Borrower (in the case of a prospective purchase of an interest in the Loan or
any other loan, upon Lender's receiving its standard confidentiality letter from
the prospective purchaser of the interest in the Loan or any other loan), any
financial or other information relating to Borrower, the Loan or the

          ----------------------

          (a) No amendment or waiver of any provision of this Agreement or any
Loan Document, and no consent with respect to any departure by Borrower
therefrom, shall be effective unless the same shall be in writing and signed by
the Required Banks (or by Agent at the written request of the Required Banks),

     8.   Credit Decision.
          ---------------

          Each Bank acknowledges that none of Agent-Related Persons has made any
representation or warranty to it, and that no act by Agent hereinafter taken,
including any review of the affairs of Borrower, shall be deemed a
representation or warranty by any Agent-Related Person to any Bank.  Each Bank
represents to Agent that, independently and without reliance upon any Agent-
Related Person and based on such documents and information as it has deemed
appropriate, that Bank has made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of Borrower, the value of and title to any and all Collateral,

inform itself as to the business, prospects, operations, property, financial and
other condition and creditworthiness of Borrower. Except for notices, reports

consummated, the Banks according to their respective Pro Rata Shares shall
indemnify upon demand Agent-Related Persons from and against any and all
Indemnified Liabilities (as defined in the Loan Documents) to the extent not
reimbursed by or on behalf of Borrower and without limiting the obligation of
Borrower to do so.  However, no Bank shall be liable for the payment to Agent-
Related Persons of any portion of such Indemnified Liabilities resulting solely
from such Agent-Related Person's gross negligence or willful misconduct.

          (b) Each Bank shall reimburse Agent upon demand for its Pro Rata Share
of any costs or expenses (including legal fees) incurred by Agent in connection
with the preparation, administration, modification, or enforcement of, or legal
advice

                                      -9-

Agent is not reimbursed for such expenses by or on behalf of Borrower.

          (c) Each Bank shall upon demand reimburse Agent for such Bank's Pro
Rata Share of any and all costs, expenses and disbursements which may be
incurred or paid by Agent in its role as Agent in connection with any action
taken by Agent to enforce or protect any Collateral, for which Agent has not
previously been reimbursed by Borrower, including reasonable fees of attorneys,
appraisers and inspectors (which includes reasonable charges for services
rendered by attorneys, appraisers or inspectors who are employees of Agent).  If
Agent subsequently recovers any such expense from Borrower or any third party,
Agent shall reimburse each Bank according to that Bank's Pro Rata Share of the
recovery.

          (d) Each Bank is severally but not jointly liable according to its Pro
Rata Share to Borrower under the Loan Documents.  Each Bank agrees to indemnify
the other Banks and Agent with respect to claims, liabilities, damages or losses
arising out of the failure of said indemnifying Bank to meet its obligations
under the Loan Documents and this Agreement.

          (e) The undertakings in this Section shall survive the payment of all
obligations hereunder and the resignation or replacement of Agent.

     10.  Insurance, Taxes, Protective Advances.
          -------------------------------------

          If Agent fails to receive satisfactory evidence that all premiums for
the insurance policies required by the Loan Documents, if any, or all taxes or
assessments on the Collateral have been paid within thirty (30) days of when
due, Agent in its sole discretion shall have the right but not the obligation to
obtain current coverage or to pay such taxes or assessments, as appropriate, and
to require the Banks to advance funds to pay the premiums or costs for it in
accordance with their respective Pro Rata Shares.

     11.  Agent in Individual Capacity; Conflict of Interest.
          --------------------------------------------------

                                     -10-
<PAGE>

          The Banks acknowledge that Agent and its Affiliates now or in the
future may have banking or other financial relationships, including being an
agent on other loans, with Borrower and its Affiliates, as though BankAmerica
were not Agent hereunder and without notice to or consent of the Banks.  Each
Bank hereby expressly waives any objection to such actual or potential conflict
of interest, (subject however to the right of the Banks to replace Agent as
provided herein or in the Loan Documents).  The Banks acknowledge that in the
course of such activities BankAmerica or its Affiliates may receive information
regarding Borrower or its Affiliates and acknowledge that Agent shall be under
no obligation to provide such information to them, whether or not confidential.
With respect to the Loan, BankAmerica shall have the same rights and powers
under this Agreement and the Loan Documents as any other Bank and may exercise
the same as though it were not Agent, and the terms "Bank" and "Banks" include
BankAmerica in its individual capacity.

     12.  Collateral Matters.  The Loan is initially unsecured.  In certain
          ------------------
cases provided for in the Loan Documents, all or a portion of any amounts
outstanding under the Loan may be secured.  In that event, the following
provisions and any other provisions of this Agreement relating to Collateral
shall apply.

          (a) Agent is authorized on behalf of all the Banks to take any action
with respect to any Collateral or the Collateral Documents which may be
necessary to perfect and maintain the security interest in and liens upon the
Collateral.

          (b) The Banks irrevocably authorize Agent to release, at its option
and in its discretion, any lien granted to or held by Agent upon any Collateral
(i) upon termination of or payment in full of the Loan and all other Obligations
under the Loan Documents; (ii) constituting Collateral sold or to be sold or
disposed of as part of or in connection with any disposition permitted under the
Loan Documents; or (iii) upon authorization in writing by the Required Banks.
Upon request by Agent, the Banks will confirm in writing Agent's authority to
release particular types or items of Collateral.

          (c) Each Bank agrees with the other Banks that Borrower's obligation
to such Bank under the Loan Documents is not and shall not be secured by any
real property collateral now or hereafter acquired by such Bank other than the
real property described in the Collateral Documents.  This provision is not
intended for the benefit of Borrower.

     13.  Collections of Payments by Agent.
          --------------------------------

                                     -11-
<PAGE>

          (a) Agent shall have the exclusive right to collect from Borrower or
any guarantors, or third parties, on account of the Loan, including principal,
interest, fees, protective advances and prepayment premiums (if any), whether
such sums are received directly from Borrower, any guarantors, or any other
persons, or obtained by right of offset by Agent of any kind, by sale of any
Collateral, or by enforcement of the Loan Documents.  Agent will receive and
hold all collections with respect to the Loan (other than the Swing Loan) for
the benefit of the Banks in accordance with their Pro Rata Shares.

          (b) If any Bank shall receive any payments or property in connection
with the Loan (whether or not voluntary), except from Agent, that Bank shall
transfer to Agent all such funds or property within one Banking Day of receipt.

          (c) No Bank shall independently initiate any judicial action or other
similar proceeding or action against Borrower with respect to the Loan.

          (d) If Agent declares that an Event of Default (as defined in any Loan
Document) has occurred and that Agent is treating the Loan as "in workout", then
all collections thereafter shall be applied first to Agent's fees and costs of
collection, then to the payment of interest pursuant to the Loan Documents and
then to the balance of unpaid principal.  All losses shall be borne by each Bank
to the extent of each Bank's Pro Rata Share.

          (e) Except as otherwise provided in the Loan Documents or this
Agreement, when Agent receives a payment of principal, interest or other amount
of funds in connection with the Loan, Agent will pay over to each Bank (or
retain, if appropriate), such Bank's portion of that payment determined as set
forth in the Loan Documents and any Assignment and Assumption Agreements.

     14.  Withholding Tax.
          ---------------

          All taxes due and payable on any payments to be made to a Bank under
this Agreement shall be such Bank's sole responsibility, except to the extent
such taxes are actually reimbursed by Borrower under the Loan Documents.  All
payments to be made to each Bank under this Agreement shall be made after
deduction for any taxes, charges, levies or withholdings which are imposed by
the country of incorporation of Borrower, the United States of America or any
other applicable taxing authority.  Each Bank agrees to provide to Agent
completed and signed copies of any forms that may be required by the United
States Internal Revenue Service (and any applicable state authority) in order to
certify such Bank's exemption from or reduction of United States (or applicable
state) withholding taxes with respect to payments to be made to such Bank under
this Agreement or the Loan Documents.
<PAGE>

          Each Bank agrees to promptly notify Agent of any change which would
modify or render invalid any claimed exemption or reduction, or of any sale,
assignment, participation, or other transfer by such Bank of all or part of its
interest in the Loan.  If any Governmental Authority of the United States or
other jurisdiction asserts a claim that Agent did not properly withhold tax from
amounts paid to or for the account of any Bank, such Bank shall indemnify Agent
fully for all amounts paid by Agent as tax or otherwise, including penalties and
interest, and including any taxes imposed by any jurisdiction on the amounts
payable to Agent under this Section, together with all costs and expenses
(including legal expenses).  The obligation of the Banks under this subsection
shall survive the payment of all Obligations and the resignation or replacement
of Agent.

     15.  No Set-off.
          ----------

          Each Bank hereby acknowledges that the exercise by any Bank of offset,
set-off, banker's lien, or similar rights against any deposit account or other
property or asset of Borrower whether or not located in California, could result
under certain laws in significant impairment of the ability of all Banks to
recover any further amounts in respect of the Loan.  Therefore, each Bank agrees
not to charge or offset any amount owed to it by Borrower relating to or arising
from the Loan or the Loan Documents against any of the accounts, property or
assets of Borrower or any of its Affiliates held by such Bank, without the prior
written approval of Agent and the Required Banks.

     16.  Notice of Default.
          -----------------

          Except for defaults in the payment of principal, interest and fees
payable to Agent for the account of the Banks and such other Obligations for
which Agent is expressly responsible for determining Borrower's compliance,
Agent shall not be deemed to have knowledge or notice of the occurrence of any
Default or Event of Default, unless Agent shall have received written notice
from a Bank or Borrower referring to the Loan, describing such Default or Event
of Default and stating that such notice is a "notice of default".  Agent will
notify the Banks of its receipt of any such notice.  Agent shall take such
action with respect to such Default or Event of Default in accordance with the
provisions of this Agreement and the Loan Documents.

     17.  Borrower's Default; Enforcement.
          -------------------------------

          Upon the occurrence of an Event of Default under any Loan Document,
the Required Banks shall have the right, upon written notice to Agent, to
require that Agent exercise the rights of the Banks as directed by the Required
Banks; provided, however, that the Banks shall indemnify, exonerate and hold
Agent harmless from and

                                     -13-
<PAGE>

against any and all claims, losses, liabilities, damages and costs (including
reasonable legal fees) incurred by Agent as a result of any such exercise of
rights at the direction of the Banks.

     18.  Foreclosure.
          -----------

          (a) Upon the occurrence of any Event of Default, if the Borrower has
secured its obligations under the Loan Documents with any Collateral, any Bank
may request that Agent take any action described in subsection (b) below.  After
receiving any such request, Agent shall promptly send or deliver to each Bank a
written request for consent to the proposed action.  Each Bank shall respond to
Agent in writing, expressly agreeing or disagreeing with the proposed action,
within twenty days (or such shorter period as may be required by Agent) after
receiving the request for consent.  Any failure of any Bank to deliver timely
notice of its agreement or disagreement shall be deemed for all purposes to be
consent to the proposed action.  Upon receipt of the Banks' responses, Agent
shall take the proposed action if the action has received consent by the
Required Banks.

          (b) Subject to the procedures in subsection (a) above and the
provisions of Section 19 below on Workout, Agent, to the extent permitted by law
and the Loan Documents, shall:

              (i)   Record a notice of default initiating a nonjudicial
     foreclosure of any deed of trust; or

              (ii)  Postpone any duly scheduled foreclosure sale for more than
     thirty (30) days except as otherwise required by law; or

              (iii) Commence any judicial foreclosure proceeding; or

               (iv) Make a motion for appointment of a receiver.

     19.  Workout.
          -------

          If Borrower is in material default under the Loan Documents
(including, but not limited to, non-payment by Borrower of amounts due and/or
bankruptcy by Borrower) and has not cured the default within any applicable cure
period, Agent may declare by written notice to the Banks that the Loan is "in
workout" (the "Notice of Workout").  The Banks acknowledge that workouts of
defaulted loans usually are resolved by either a borrower cure of the default;
or a restructure of or other modification to the loan; or by exercising banks'
remedies, including, but not limited to, foreclosure on any collateral; and that
it is in the interest of the Banks to attain a

                                     -14-
<PAGE>

resolution within a reasonable period of time. Therefore the Banks agree that
if, after one hundred eighty (180) days from the date of Agent's Notice of
Workout, there has been neither a cure of the default(s), nor a restructure nor
other modification executed, nor exercise of the Banks' remedies under Sections
17 or 18 above, then (a) if the Loan is then unsecured, Agent on behalf of the
Banks shall sue Borrower and any guarantors for collection of amounts owing to
the Banks, subject to and in accordance with advice of Agent's counsel; and (b)
if the Loan is then secured, Agent on behalf of the Banks shall foreclose on the
Collateral and pursue related remedies, subject to and in accordance with advice
of Agent's counsel (and provided there are no environmental, legal or similar
problems with the Collateral to cause Agent to reasonably believe it undesirable
to foreclose on said Collateral). Notwithstanding any action by Agent under
subsections (a) or (b) herein, Agent shall follow the direction of the Required
Banks under Sections 17 or 18 above at any time.

          Notwithstanding the foregoing, at any time from the inception of the
Loan until the repayment thereof in full, unless and until the Required Banks
shall direct Agent to the contrary, Agent shall have the right but not the
obligation to take such action as it may deem appropriate to preserve the
Collateral, protect the security interest of the Banks therein and preserve the
rights of the Banks to recover any amounts owing under the Loan Documents,
without the consent of the Required Banks.

     20.  Bankruptcy of Borrower.
          ----------------------

          In the event of a bankruptcy by Borrower, the Banks shall act through
Agent to petition the court, make any motion for relief from the automatic stay,
participate in any appropriate creditors' committee, vote on a plan of
reorganization or pursue other remedies or actions in accordance with the
approval of the Required Banks.

     21.  Acquisition of Collateral.
          -------------------------

          If all or any portion of any Collateral is acquired by foreclosure or
by deed in lieu of foreclosure, Agent shall take title to the Collateral in its
name or by an affiliate of Agent, but for the benefit of all Banks in their Pro
Rata Shares on the date of the foreclosure sale or recordation of the deed in
lieu of foreclosure (the "Acquisition Date").  Agent and all Banks hereby
expressly waive and relinquish any right of partition with respect to any
Collateral so acquired.

     22.  Property Manager.
          ----------------

                                     -15-
<PAGE>

          After any Collateral is acquired as provided in Section 21 above,
Agent in its sole discretion shall appoint and retain as manager of the
Collateral (the "Property Manager") a person or company experienced in the
management of similar properties.  Agent shall have no liability for any
wrongful act or omission on the part of the Property Manager.

     23.  Business Plan; Required Consent.
          -------------------------------

          After consulting with the Property Manager, Agent shall prepare a
written plan for sale, leasing, management, completion of construction (if
required), maintenance, repair or improvement of any Collateral and a budget for
the aforesaid which may include a reasonable management fee payable to Agent
(the "Business Plan").  The Business Plan shall include a proposed price at
which the Collateral shall be listed for sale and a minimum sales price at which
the Collateral shall be sold and any requirements for a qualified bidder.  Agent
will deliver a draft Business Plan not later than the sixtieth (60th) day after
the Acquisition Date to each Bank with a written request for consent to the
Business Plan.  Each Bank shall respond to Agent in writing, expressly approving
or disapproving the Business Plan within twenty (20) days after receiving the
request for consent.  Any failure of any Bank to deliver timely notice of its
approval or disapproval of the Business Plan shall be deemed for all purposes to
be approval of the Business Plan.  If the Business Plan receives approval by the
Required Banks, Agent and the Property Manager shall adhere to the Business Plan
until a different Business Plan is approved by the Required Banks.  Agent may
propose an amendment to the Business Plan as it deems appropriate, which shall
also be subject to Required Bank approval.  If the Business Plan (as may be
amended) proposed by Agent and the Property Manager is not approved by the
Required Banks, (or if six (6) months  have elapsed following the Acquisition
Date without a Business Plan being proposed by Agent), any Bank may propose an
alternative Business Plan, which Agent shall submit to all Banks for their
approval or disapproval following the procedures provided in this Section.

          Notwithstanding any other provision of this Agreement, Agent shall
have the right but not the obligation to take any action in connection with the
Collateral, upon written notice to Banks but without their actual or deemed
approval, if Agent reasonably believes that (i) such action is necessary to
preserve the value of the Collateral and (ii) the value of the Collateral is
likely to deteriorate during the time period otherwise required to obtain
approval hereunder.

                                     -16-
<PAGE>

     24.  Income and Expenses.
          -------------------

          (a) During the period the Collateral is held by Agent for the benefit
of the Banks, all income, expense (including attorney's fees) and liabilities
arising out of the management and possession of the Collateral shall be shared
by the Banks in accordance with their Pro Rata Shares.

          (b) Agent will keep or cause to be kept books of account of receipts
and disbursements and other financial activities with respect to the Collateral.
The books will be kept on a calendar year ending on December 31, with a tax year
for income tax purposes ending December 31, and in a manner and form consistent
with Agent's methods and procedures of reporting such transactions.

     25.  Disposition of the Collateral.
          -----------------------------

          Upon approval of the Business Plan, Agent shall cause the Collateral
to be listed with a licensed real estate broker experienced in the sale of
similar properties at the listing price provided in the Business Plan.  If Agent
receives any all cash offer equal to or greater than the minimum sales price and
meets the other requirements in the Business Plan, Agent shall accept that offer
prior to its expiration.  Upon closing of the sale of the Collateral, the net
proceeds shall be distributed to the Banks in accordance with their Pro Rata
Shares.

     26.  Holding Agreement.
          -----------------

          Agent may, and at request of the Required Banks shall, propose a more
detailed agreement among the Banks and Agent concerning holding of any
Collateral after the Acquisition Date (a "Holding Agreement") to supplement or
supplant this Agreement.  Such Holding Agreement shall be binding on all Banks
if it is approved by Agent and the Required Banks.

     27.  Effect of Agreement and Relationship of Parties.
          -----------------------------------------------

                                     -17-
<PAGE>

          This Agreement is not intended to establish a partnership or joint
venture between Agent and the Banks.  The provisions of the Loan Documents
regarding the relationships among Agent and the Banks and this Agreement are
intended solely to facilitate co-lending relationships among the Banks for the
Loan.  No security or investment contract under any federal or state law is
intended to be created among the Banks or between Agent and the Banks.  The
execution of this Agreement, the performance of the terms hereof, and the Banks'
purchase of and ownership interest in the Loan and the Loan Documents shall not
constitute any Bank as owner, purchaser or seller of any security (as that term
is defined in the Securities Act of 1933 or the Securities Exchange Act of 1934)
issued, owned, purchased or sold by BankAmerica or any of its subsidiaries or
affiliates, either as principal or as agent for Borrower.  Each Bank is
purchasing and acquiring legal and equitable ownership of its Pro Rata Share and
is not making a loan to BankAmerica, and no debtor-creditor relationship exists
between them as a result of this Agreement.  This Agreement and the Loan
Documents constitute the entire agreement among the parties, and no
representation, promise, inducement or statement of intent has been made by
Agent to the Banks which is not embodied in this Agreement or the Loan
Documents.

     28.  Arbitration and Judicial Reference.
          ----------------------------------

          The provisions of the Loan Agreement regarding arbitration and
judicial reference shall apply to any controversies or claims (a) between
Borrower on one hand and Agent and the Banks on the other and (b) between or
among Agent and the Banks.

     29.  Counsel.
          -------

          The Banks acknowledge that Agent's counsel has represented and shall
represent only Agent in connection with the Loan Documents and this Agreement.
Each other Bank shall retain independent legal counsel regarding all such
matters, documents and agreements.  After an Event of Default, the Banks shall
enter into a joint privilege agreement regarding the exchange of information
that is or may be subject to attorney-client privilege or related privileges.
Agent's counsel shall prepare such joint privilege agreement, subject to the
approval of the Required Banks which approval shall not be unreasonably withheld
by any Bank.

     30.  Successors and Assigns.
          ----------------------

          The terms and provisions of this Agreement shall be binding upon and
inure to the benefit of Agent and the Banks and their respective successors and
assigns.  Each Bank becoming a party to the Loan Documents shall automatically
be considered a party hereto and shall be entitled to the rights and subject to
the obligations of a Bank hereunder.  This Agreement is solely for the benefit
of the

                                     -18-
<PAGE>

parties hereto and their successors and assigns and no third party (including
Borrower or any guarantor) shall have any rights or benefits hereunder.

     31.  Notices.
          -------

          All notices, requests and other communications shall be in writing and
mailed, faxed or delivered to the address or facsimile number specified for
notices in the Loan Documents or an Assignment and Assumption Agreement; or, to
such other address as shall be designated by such party in a written notice to
the other parties.  Any agreement of Agent to receive certain notices from the
Banks by telephone or facsimile is solely for the convenience and at the request
of the Banks.  Agent shall be entitled to rely on the authority of any Person
purporting to be an authorized Person, and Agent shall not have any liability to
the Banks or any other Person on account of any action taken or not taken by
Agent in reliance upon such telephonic or facsimile notice.

     32.  Relationship to Loan Documents.
          ------------------------------

          (a) The parties hereto acknowledge that this Agreement is meant to
supplement and not to abrogate the terms of the Loan Documents.  All provisions
of this Agreement shall be read so as to be compatible with the provisions of
the Loan Documents; provided, however, that with respect to matters concerning
the relationship among the Banks and Agent, in the event of any conflict or
inconsistency between a term or provision contained herein and a term or
provision contained in the Loan Documents, the term or provision contained
herein shall govern.

          (b) In case of an inconsistency between this Co-Lender Agreement and
the Loan Documents, the provisions of the Loan Documents shall govern, except as
otherwise provided in subsection (a) above.

          The parties hereto have executed this Agreement as of the date first
indicated above.

                          FIRST AMENDED AND RESTATED
                            MODIFICATION AGREEMENT
                   TO SYNDICATE $120,000,000 REVOLVING LOAN
                           TO ESSEX PORTFOLIO, L.P.


          This First Amended and Restated Modification Agreement ("Agreement")
is made as of May 16, 2000, by the several financial institutions from time to
time party to this Agreement (collectively, the "Banks," and individually a
"Bank"), Bank of America, N.A. ("BankAmerica") as one of the Banks and as
administrative agent ("Agent") for the Banks, and Essex Portfolio, L.P., a
California limited partnership ("Borrower").


                               Factual Background
                               ------------------

     A.   Banks agreed to make an unsecured revolving line of credit loan (the
"Loan") to Borrower in accordance with that certain Revolving Loan Agreement
dated May 11, 1998 (the "Existing Agreement").  The Loan was evidenced by a Note
(the "Existing Note") dated May 11, 1998, in the stated principal amount of One
Hundred  Million Dollars ($100,000,000).  Each of the Banks, including
BankAmerica, have a direct lender relationship with Borrower in accordance with
the Loan Documents, as hereby amended.  The Banks designated BankAmerica as
Agent to act as their Administrative agent in the syndicated Loan.  Because
BankAmerica was both an individual Bank in the syndicate and Agent for all of
the Banks in the syndicate, the parties wished to modify certain defined terms
in the Loan Documents.

     B.   Other documents executed in connection with the Loan  include a
Payment Guaranty executed by Essex Property Trust, Inc.

     C.   The Existing Agreement provided for funding of a disbursement of the
Loan within three (3) Business Days of Borrower's request.  Borrower desires
same-day funding of disbursements.  To accommodate Borrower, BankAmerica has
agreed that at its discretion it will fund disbursements on the day Borrower
makes a request under the terms of a so-called swing line and that the swing
line will be repaid from the syndicated Loan when the syndicated Loan is funded
at the end of the two (2) Business Days called for in the Existing Agreement.
To document the swing line, Borrower and Bank would like to amend and restate
the Existing Agreement.

                                      -1-

     D.   BankAmerica,  Bank of America, N.A. as Agent, Banks, Banc of America
Securities, LLC as Sole Lead Arranger and Sole Book Manager, Union Bank of
California, N.A. and Bank One, N.A. as Co-Syndication Agents, Essex Property
Trust, Inc. as Guarantor, and Borrower have entered into that certain First
Amended and Restated Revolving Loan Agreement (the "Loan Agreement") dated as of

     4.   The Credit.
          ----------

          (a) Subject to the terms and conditions hereof, each Bank agrees to
fund its Pro Rata Share of each Advance of the Line of Credit Loan proceeds from
time to time (other than an advance of the Swing Loan) until the maturity date
of the Loan.  Such Line of Credit Loan proceeds shall be delivered to Borrower
in accordance with the provisions of the Loan Documents.

          (b) Borrower and each Bank acknowledge that as of the date of this
Agreement, the Line of Credit Loan and the amount outstanding thereunder, and
each Bank's Pro Rata Share of the Loan (not including the Swing Loan), are as
follows:

              (i)  The Line of Credit Loan:    $120,000,000
              (ii) On the Effective Date of this Agreement, each Bank's Pro
     Rata Share of the Line of Credit Loan shall be as follows:

                   BankAmerica:             29.17%    $ 35,000,000
                   Union Bank:              20.83%    $ 25,000,000
                   Bank One:                20.83%    $ 25,000,000

                                           ------     ------------
                                           100.00%    $120,000,000

          (c) Each Bank shall become vested with its Pro Rata Share of the Line
of Credit Loan (not including the Swing Loan) upon execution and delivery of the
required documents and upon payment of its Pro Rata Share of the principal
balance of the Line of Credit Loan outstanding and any other fees, costs or
expenses due hereunder or pursuant to another agreement.  Upon such payment, the
respective interests of each Bank in the Loan Documents and the other rights

                                      -6-
<PAGE>

and claims with respect to the Line of Credit Loan (not including the Swing
Loan) shall be of equal priority with one another, except as otherwise expressly
provided.

          (d) Each Bank shall be deemed to have unconditionally and irrevocably
purchased a pro rata risk participation from the Swing Line Lender in the Swing
Loans, without recourse or warranty, in an amount equal to such Bank's Pro Rata
Share of such Swing Loans.  In addition, from and after the date that any Bank
funds such participation, such Bank shall, to the extent of its Pro Rata Share,
be entitled to receive a ratable portion of any payment of principal and/or
interest received by the Swing Line Lender on account of such Swing Loans,
payable to such Bank promptly upon such receipt.

          (e) A complete set of Loan Documents shall be held by Agent.

          (f) A Bank which is not Agent shall have no interest in any (i)
property taken as security for any other loan or financial accommodation made or
furnished to Borrower by Agent (in which such Bank has not acquired an
interest); (ii) property now or hereafter in Agent's possession or under Agent's
control other than by reason of the Loan Documents; or (iii) deposits which may
be or might become security for Borrower's Obligations by reason of the general
description contained in any instrument not a Loan Document held by Agent or by
reason of any right of setoff, counterclaim, banker's lien or otherwise.  If,
however, such property shall actually be applied to the payment of amounts owing
by Borrower in connection with the Loan, then each Bank shall be entitled to its
Pro Rata Share, if any, of such application to the Loan.

          (g) All the parties agree that, except as may be otherwise expressly
provided, all of the interest rates for the Line of Credit Loan are those of and
are calculated in accordance with the requirements and any applicable
assessments of Agent, regardless of which Bank is making an Advance or receiving
a payment thereon.

          (h) Notwithstanding each Bank's Pro Rata Share, a Bank may agree in
writing for Agent (or another Bank) to retain, as additional compensation, a
percentage of certain payments of interest and fees payable to said Bank, which
Agent, if payable to it, may deduct from amounts paid by it to said Bank.  If
said additional compensation is payable to another Bank and if Agent is
requested and agrees to withhold and pay out as appropriate said percentage of
said payments, Agent shall be entitled to charge a service fee to be deducted
from each such payment.  Nothing in this Subsection 4(h) shall require Borrower
to pay any fees

                                      -7-
<PAGE>

not expressly required by other terms of the Loan Documents.

     5.   Appointment and Authorization of Agent.
          --------------------------------------

          (a) Each Bank hereby irrevocably appoints, designates and authorizes
Agent to take such action on its behalf under the provisions of this Agreement
and each other Loan Document and to exercise such powers and perform such duties
as are expressly delegated to it by the terms of this Agreement or any other
Loan Document, together with such powers as are reasonably incidental thereto
and as further provided in any Co-Lender Agreement, as amended, described below.

          (b) Subject to the limitations set forth in the Loan Documents and any
Co-Lender Agreement, as amended, Agent's powers include but are not limited to
the power:  (i) to administer, manage and service the Line of Credit Loan; (ii)
to enforce the Loan Documents; (iii) to make all decisions under the Loan
Documents in connection with the day-to-day administration of the Line of Credit
Loan, any inspections required by the Loan Documents, and other routine
administration and servicing matters; (iv) to collect and receive from Borrower
or any third persons all payments of amounts due under the terms of the Loan
Documents and to distribute the amounts thereof to the Banks; (v) to collect and
distribute or disburse all other amounts due under the Loan Documents; (vi) to
grant or withhold consents, approvals or waivers, and make any other
determinations in connection with the Loan Documents; and (vii) to exercise all
such powers as are incidental to any of the foregoing matters.  Agent shall
furnish to the Banks copies of material documents, including confidential ones,
received from Borrower regarding the Loan (including the Swing Loan), the Loan
Documents and the transactions contemplated thereby.  Agent shall have no
responsibility with respect to the authenticity, validity, accuracy or
completeness of the information provided.

          (c) Notwithstanding any provision to the contrary contained in any
Loan Document, Agent shall not have any duties or responsibilities, except those
expressly set forth in the Loan Documents or any Co-Lender Agreement, as
amended, nor shall Agent have any fiduciary relationship with any Bank, and no
implied covenants, responsibilities, duties, obligations or liabilities shall be
read into this Agreement or any other Loan Document against Agent.

          (d) Borrower acknowledges that the Banks have executed and

                                      -8-
<PAGE>

amended, or may execute and amend, a Co-Lender Agreement to supplement the Loan
Documents with respect to the relationship of the Banks and Agent among
themselves in connection with the Loan. The Co-Lender Agreement, as amended, is
not a Loan Document, and shall not increase, decrease or otherwise modify any of
the rights or obligations of Borrower under the terms of the Loan Documents.

          (e) An Agent (the "Resigning Agent") may, and at the request of the
Required Banks shall, resign as Agent upon thirty (30) days' notice to the
Banks.  If Resigning Agent resigns under this Agreement, the Required Banks
shall appoint from among the Banks a successor administrative agent to act in
the place of the Resigning Agent.  If no successor administrative agent is
appointed prior to the effective date of the resignation of Resigning Agent,
Resigning Agent may appoint, after consulting with the Banks, a successor
administrative agent from among the Banks which would qualify as an Eligible
Assignee.  Upon the acceptance of appointment as successor agent hereunder, such
successor agent shall succeed to all the rights, powers and duties of the
Resigning Agent and the term "Agent" as it originally applied to the Resigning
Agent shall mean such successor administrative agent, and the Resigning Agent's
appointment, powers and duties as Agent shall terminate.  After any Resigning
Agent's resignation hereunder as Agent, the provisions regarding payment of
costs and expenses and indemnification of Agent shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Agent under this
Agreement.  If no successor administrative agent has accepted appointment as
Agent by the date which is thirty (30) days following a Resigning Agent's notice
of resignation, the Resigning Agent's resignation shall nevertheless thereupon
become effective, and the Banks shall perform all of the duties of Agent
hereunder until such time, if any, as the Required Banks appoint a successor
administrative agent.

          Upon replacement of a Resigning Agent as provided in this Agreement,
the  Resigning Agent shall promptly deliver to the new Agent copies of any
books, records, and documents related to the Loan then in the Resigning Agent's
possession to which the Banks are entitled.

     6.   Loan Accounts.
          -------------

                                      -9-
<PAGE>

          The Advances made by each Bank shall be evidenced by one or more loan
accounts or records maintained by such Bank and Agent in the ordinary course of
business.  The loan accounts or records maintained by Agent and each Bank shall
be conclusive absent manifest error of the amount of the Loan made by the Banks
to Borrower and the interest and payments thereon.  Any failure so to record or
any error in doing so shall not, however, limit or otherwise affect the
obligation of Borrower hereunder to pay any amount owing with respect to the
Loan.

     7.   Procedure for Borrowing.
          -----------------------

          (a) Each Advance shall be made upon Borrower's irrevocable written
Notice of Borrowing delivered to Agent in accordance with the Loan Agreement.

          (b) Agent will promptly notify each Bank of any Notice of Borrowing
and of the amount of such Bank's Pro Rata Share of the Advance to be made.
Swing Line Lender may at its discretion make a Swing Loan in the amount set
forth in the Notice of Borrowing.  Each Bank shall be deemed to have
unconditionally and irrevocably purchased a portion of the Swing Loan so
advanced as provided in Section 4(d) above. The Banks acting through Agent shall
disburse the Loan as provided in the Loan Agreement.

          (c) Each Bank will make the amount of its Pro Rata Share of each
Advance available to Agent for the account of Borrower at Agent's Payment Office
by 11:00 a.m. (San Francisco time) on the borrowing date requested by Borrower
in funds immediately available to Agent. The proceeds of all such Advances will
then be made available to Borrower by Agent by wire transfer in accordance with
written instructions provided to Agent by Borrower.

          (d) Unless Agent receives notice from a Bank at least one (1) Banking
Day prior to the date of an Advance that such Bank will not make available to
Agent  when required the amount of that Bank's Pro Rata Share of the Advance,
Agent may assume that each Bank has made such amount available to Agent in
immediately available funds on the borrowing date.

          (e) The failure of any Bank to make any Advance on any borrowing date
shall not relieve any other Bank of any obligation hereunder to make an Advance
on such borrowing date, but no Bank shall be responsible for the failure of any
other Bank to make its Advance on the borrowing date.

                                     -10-
<PAGE>

          -----------------------------

          (a) Borrower may elect applicable interest rates in accordance with
the requirements, terms and conditions set forth in the Note(s) upon irrevocable
written notice to Agent to be received by Agent on the appropriate day not later
than 9:00 a.m. San Francisco time.

          (b) Agent will promptly notify each Bank of receipt of a LIBOR Rate
Election or, if no timely notice is provided by Borrower, Agent will promptly
notify each Bank of any automatic conversion to a Prime-based Rate.  All rate
elections and conversions shall be made ratably according to the respective Pro
Rata Shares of the outstanding principal amounts of the Loan held by each Bank
with respect to which the notice was given.

     9.   Facility Fee and Letter of Credit Fee.  Borrower shall pay a facility
          -------------------------------------
fee and a per annum fee relating to the letters of credit issued under the terms
of the Loan Agreement all as provided in the Loan Agreement.

     10.  Payments by Borrower.
          --------------------

          (a) All payments to be made by Borrower shall be made without set-off,
recoupment or counterclaim.  Except as otherwise provided, all payments by
Borrower (other than payments on account of the Swing Loan) shall be made to
Agent for the account of the Banks at Agent's Payment Office, and shall be made
in U.S. dollars and in immediately available funds, in accordance with the Loan
Documents.  Agent will promptly distribute to each Bank its Pro Rata Share (or
other applicable share as may be agreed by a Bank) of such payment in like funds
as received.  Any payment received by Agent later than 11:00 a.m. (San Francisco
time) shall be deemed to have been received on the following Business Day and
any applicable interest or fee shall continue to accrue.

          (b) To the extent that Borrower makes a payment to Agent or the Banks,
or Agent or the Banks exercise the right of set-off, and such payment or the
proceeds of such set-off or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required (including by
any settlement) to be repaid to a trustee, receiver, Borrower or any other
party, in connection with any Insolvency Proceeding or otherwise, then (i) to
the extent of such recovery the obligation or part thereof originally intended
to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such

                                     -11-
<PAGE>

set-off had not occurred, and (ii) each Bank severally agrees to pay to Agent
upon demand its Pro Rata Share of any amount so recovered from or repaid by
Agent.

          (c) Agent shall have the exclusive right to collect on the Line of
Credit Loan from Borrower or any guarantors, third parties, or otherwise
including principal, interest, fees, protective advances, or any prepayment
premiums, whether such amounts are received directly from Borrower, any
guarantors, or other persons, or are collected by offset by Agent against the
money or other property of Borrower or any guarantors deposited at or held by
Agent, or other enforcement of the Loan Documents.  No Bank shall independently
initiate any judicial action or equivalent action or other proceeding against
Borrower with respect to the Loan.

     11.  Prepayments, Termination or Reduction of Loan.
          ---------------------------------------------

          (a) In the event Borrower elects to pay down the Line of Credit (as
that term is defined in the Loan Agreement) or to otherwise prepay the Loan in
whole or in part in accordance with the Loan Documents, Agent will promptly
notify each Bank of such notice and of each Bank's Pro Rata Share of such
prepayment.  Any reduction or termination of the Loan (other than Swing Loans)
shall be applied to each Bank according to its Pro Rata Share.  All accrued
commitment fees up to but not including the effective date of any reduction or
termination of the Loan shall be payable on the effective date of such reduction
or termination.

     12.  Usury.
          -----

          If a court ultimately determines that the Loan (or an Advance)
violates applicable usury law, then (a) Borrower shall not be required to pay to
a Bank interest on the Line of Credit Loan (or the Advance) at a rate in excess
of the maximum rate that may be lawfully charged under applicable law; and (b)
in the event that any Bank shall collect interest or other monies which are
deemed to constitute interest which would increase the effective interest rate
on the Line of Credit Loan (or an Advance) to a rate in excess of that permitted
by applicable law, such excess interest shall, at the option of said Bank, be
returned to Borrower or credited against the principal balance of the Line of
Credit Loan (or Advance) then outstanding; (c) provided, however, that if a
usury law applies to one or more but not all Banks, then the Banks not affected
by the usury law shall be entitled to the full amount of interest from Borrower
under the Loan Documents even though other Banks may receive or retain less due
to the usury law.

                                     -12-
<PAGE>

     13.  Increased Costs and Reduction of Return.
          ---------------------------------------

          (a) If any Bank shall have determined that a change in or compliance
with any Capital Adequacy Regulation affects the amount of capital required to
be maintained by the Bank or any Person controlling the Bank, and such Bank
determines that the amount of such required capital is or will be increased as a
consequence of the Loan or other obligations under the Loan Documents taking
into consideration such Bank's or such Person's policies with respect to capital
adequacy and desired return on capital, then, upon sixty (60) days notice from
such Bank to Borrower through Agent, Borrower shall pay to the Bank an
additional amount sufficient to compensate the Bank for such increase.

          (b) Upon the receipt by Borrower from any Bank (an "Affected Bank") of
a claim for reimbursement or compensation hereunder, Borrower may:  (i) request
the Affected Bank to use its best efforts to obtain a replacement bank or
financial institution satisfactory to Borrower and Agent to acquire and assume
all or part of such Affected Bank's Commitment (a "Replacement Bank"); or (ii)
request one or more of the other Banks to acquire and assume all or part of such
Affected Bank's Commitment.

     14.  Costs and Expenses.
          ------------------

          (a) Borrower shall pay or reimburse Agent for the benefit of each Bank
within five (5) Banking Days after demand for all costs and expenses, including
all legal, audit, review, fees and expenses (including the allocated cost of
such services by Agent's employees) incurred by Agent in connection with the

administration while the Loan is not in default), and execution of any Loan
Document and any amendment, supplement, waiver or modification and any other
documents prepared in connection herewith or therewith, (whether or not the
particular Loan, transaction or document is consummated).

          (b) Borrower shall pay or reimburse Agent for the benefit of each Bank
within five (5) Banking Days after demand for all costs and expenses, including
all legal, audit, review, fees and expenses (including the allocated cost of
such services by Agent's employees) incurred by Agent in connection with the

the Loan, and any Insolvency Proceeding, judicial proceeding or arbitration).

          ---------------------------

          Borrower shall indemnify, defend and hold Agent-Related Persons, and

liabilities, obligations, losses, damages, actions, judgments, costs, and
expenses (including legal fees) which may be incurred by or asserted against any
such Person arising out of or relating to the Loan or the Loan Documents or any
document or transaction or action taken or not by any such Person in connection
with any of the foregoing, including any investigation, arbitration, litigation,
Insolvency Proceeding or other proceeding whether or not any Indemnified Person
is a party thereto (all the foregoing, collectively, the "Indemnified
Liabilities"); provided, that Borrower shall have no obligation hereunder to any
Indemnified Person with respect to Indemnified Liabilities except to the extent
resulting from the gross negligence or willful misconduct of such Indemnified
Person. The agreements in this Section shall survive payment of all other
Obligations.

     16.  Assignments, Participations, etc.
          ---------------------------------

          (a) A Bank may at any time assign to one or more Eligible Assignees
(each an "Assignee") with the written consent of Agent (at all times), which
consent shall not be unreasonably withheld (provided that no written consent
shall be required for an Eligible Assignee that is an Affiliate of such assignor
Bank) all or part of its Pro Rata Share of the Line of Credit Loan and the other
rights and obligations of such assignor Bank hereunder, in a minimum amount of
Ten Million Dollars ($10,000,000) and in additional increments of One Million
Dollars ($1,000,000); provided, however, that no such assignment shall be
permitted if the effect thereof is to cause the remaining Commitment of the
assignor Bank to be less than Ten Million Dollars ($10,000,000), provided
further that, these restrictions on dollar amounts notwithstanding, a Bank may,
subject to the other requirements of this Section and this Agreement, at any
time, assign one hundred percent (100%) of its Pro Rata Share of the Line of
Credit Loan.  However, such assignment shall be conditioned on, and Borrower and
Agent may continue to deal solely and directly with such assignor Bank until,
(i) written notice of such assignment, substantially in the form of the attached
Exhibit A shall have been given to Borrower and Agent by such Bank and the
Assignee; (ii) such Bank and its Assignee shall have delivered to Agent and
Borrower an Assignment and Assumption Agreement substantially in the form of the
attached Exhibit B

                                     -14-
<PAGE>

("Assignment and Assumption Agreement") (together with any Note(s) subject to
such assignment) and (iii) the Assignor has paid or caused to be paid to Agent a
processing fee in the amount of Three Thousand Dollars ($3,000).

          (b) From the date that Agent notifies the assignor Bank that all
conditions and requirements of the assignment have been met, then to the extent
that rights and obligations hereunder have been assigned (i) the Assignee
thereunder shall be a party hereto and shall have the rights and obligations of
a Bank under the Loan Documents and any Co-Lender Agreement, as amended, (ii)
the assignor Bank shall relinquish such assigned rights and be released from
such assigned obligations under the Loan Documents, (iii) this Agreement shall
be deemed to be amended to the extent necessary to reflect the addition of the
Assignee and the resulting adjustment of the Pro Rata Shares of the Line of
Credit Loan arising therefrom, and (iv) the Pro Rata Share allocated to an
Assignee shall reduce the Pro Rata Share of the assigning Bank.

          (c) A Bank (the "originating Bank") may sell to one or more Persons
not Affiliates of Borrower (a "Participant") participating interests in the Line
of Credit Loan; provided that (i) the originating Bank's obligations under the
Loan Documents and any Co-Lender Agreement, as amended,  shall remain unchanged,
(ii) the originating Bank shall remain solely responsible for the performance of
such obligations, (iii) Borrower and Agent shall continue to deal solely and
directly with the originating Bank in connection with the Line of Credit Loan
and Loan Documents, (iv) no Bank shall transfer or grant any participating
interest under which the Participant has rights to approve any amendment,
consent or waiver with respect to any Loan Document, and (v) each participating
interest shall be in a minimum amount of Ten Million Dollars ($10,000,000), and
no such participation shall be permitted if the non-participated interest of the
originating Bank would thereafter be less than Ten Million Dollars
($10,000,000).  A Participant shall not have any rights under the Loan Documents
or any Co-Lender Agreement, as amended, and all amounts payable by Borrower
hereunder shall be determined as if the originating Bank had not sold such
participation.

          (d) Notwithstanding any other provision, a Bank may pledge its
interest in the Loan in favor of any Federal Reserve Bank in accordance with
Federal law.

          (e) If Agent assigns or sells all of its remaining interest in the
Line of Credit Loan, the Agent shall give each other Bank written notice of such
assignment or sale at the time of the closing of such assignment or sale.

          Each Bank agrees to exercise due care to maintain the confidentiality

any Bank may disclose such information at the request of or pursuant to any
requirement of any Governmental Authority to which the Bank is subject; or

Affiliates may be party; or to the extent reasonably required in connection with
the exercise of any remedy under any Loan Document; or to such Bank's auditors,

agreements contained herein, the parties hereto agree as follows:

     1.   Assignment and Assumption.
          -------------------------

          As of the Effective Date (defined below), the Assignor hereby sells
and assigns to the Assignee, and the Assignee hereby purchases and assumes from
the Assignor, the Assigned Amount, which includes the Assignor's interest in the
Loan and any outstanding Advances and which shall be equal to ___________
percent (___%) (the "Assignee's Pro Rata Share") of the Loan.  The assignment
set forth in this Section 1 shall be without recourse to or representation or
warranty by the Assignor (except as expressly provided in this Agreement).

          As of the Effective Date, the Assignee shall be a party to the Loan
Documents and Co-Lender Agreement and succeed to all of the rights and be
obligated to perform all of the obligations of a Bank under the Loan Documents,
with an interest in the Loan equal to the Assigned Amount.  The Assignee agrees
that it will perform all of the obligations required to be performed by it as a
Bank under the Loan Documents and the Co-Lender Agreement.  The Assignor's Pro
Rata Share of the Loan shall, as of the Effective Date, be reduced by an amount
equal to the Assigned Amount and the Assignor shall relinquish its rights and be
released from its obligations under the Loan Documents to the extent such
obligations have been assumed by the Assignee.

with the Assignee's Pro Rata Share being ____% and the Assignor's remaining
interest in the Loan will be $________________ with a remaining Pro Rata Share
of ____%.

          This Agreement is not a Loan Document.

     2.   Payments.

          As consideration for the sale, assignment and transfer contemplated in
Section 1 hereof, the Assignee shall pay to the Assignor on the Effective Date

the Effective Date.

          The Assignee agrees to pay to Bank of America, N.A., as Agent, a
processing or transfer fee in the amount of $____________________.

          The Assignee agrees to pay the Assignor, as additional compensation, a
fee in an amount equal to __________ percent (___%) of all interest and fees
paid by the Borrower to the Assignee under the Loan Documents.  Such fee shall
be payable quarterly in arrears on the last business day of _____________,
commencing on _____________, 2000.

                                 --------------
                                  (Swing Line)

$25,000,000                                                         May 16, 2000
                                                       San Francisco, California

Interest Rate Available (see attached Exhibit A):

     Prime Rate plus Applicable Prime Rate Margin (the "Prime-based Rate") (see
     Section 1(a) of attached Exhibit A)

Maturity Date: May 16, 2002 (see Section 5 below)


          1.   FOR VALUE RECEIVED, ESSEX PORTFOLIO, L.P., a California limited
partnership ("Borrower"), promises to pay to the order of BANK OF AMERICA, N.A.
("Bank"), at Bank's Real Estate Structured Debt Group Office in San Francisco,
California, or at such other place as Bank from time to time may designate, the
principal sum of Twenty-five Million Dollars ($25,000,000) (the "Maximum Loan
Amount"), or so much of that sum as may be advanced under this promissory note
("Note"), plus interest as specified in this Note.

          2.   This Note evidences a swing line (also referred to as the "Loan")
to Borrower from Bank under the Loan Agreement defined in Section 3 below, as it
may be amended.

          3.   This Note is one of several Loan Documents, as defined and
designated in that certain First Amended and Restated Revolving Loan Agreement,
dated as of May 16, 2000 (the "Loan Agreement"), as it may be amended
thereafter, by and between Borrower, and Bank and other related parties.
Capitalized terms not otherwise defined in this Note shall have the meanings
given to them in the Loan Agreement.  Some or all of the Loan Documents,
including the Loan Agreement, contain provisions for the acceleration of the
maturity of this Note.

          4.   The principal sum outstanding from time to time on this Note
shall bear interest in accordance with the formula set forth in attached Exhibit
A.

          5.   Accrued interest shall be payable on the first day of each month
in arrears.  In addition, all interest accrued shall be due and payable with any
payment or prepayment of the Loan.

                                      -1-
<PAGE>

          Until directed otherwise, all payments shall be made in accordance
with the Loan Agreement.

          6.   For purposes of this Note, "interest" shall include (a) any and
all interest payable as provided in this Note, including attached Exhibit A, as
well as (b) any and all sums ("Additional Interest") payable by Borrower under
any existing or future agreement between Borrower and Bank ("Interest Rate
Protection Agreement") which may provide for interest rate caps, collars or
swaps, or which may otherwise afford interest rate protection to all or part of
the Loan.  Borrower shall pay all Additional Interest at the times and in the
amounts specified in the applicable Interest Rate Protection Agreement and on
the terms and subject to the conditions of the Loan Agreement.  Borrower shall
pay all other interest monthly in arrears, on the first day of each month
following the date of this Note, and at such other times as may be specified in
attached Exhibit A.  All principal and all accrued and unpaid interest shall be
due and payable no later than May ___, 2002, unless the term of the Loan is
extended as provided in Section 2.2 of the Loan Agreement.
                                ---

          7.   Bank shall not be required to make any advance if to do so would
cause the principal outstanding under this Note to exceed the Swing Line
Availability (as that term is defined in the Loan Agreement).

          8.   Telefax Authorization
               ---------------------

               (a) Bank may honor telefax instructions from John D. Eudy, Keith
R. Guericke, Michael J. Schall, Mark J. Mikl or Jordan E. Ritter for advances or
repayments described in the Note given by any one of the individuals authorized
to sign loan agreements on behalf of Borrower, or any other individual
designated by any one of such authorized signers.

               (b) Advances and repayments will be either (i) deposited in and
repayments will be withdrawn from Borrower's account number 14228-02371, or such
other of Borrower's accounts with Bank as designated in writing by Borrower, or
(ii) wire transferred at Borrower's written direction, telefaxed as set forth in
the Loan Agreement.

          9.   Borrower may prepay some or all of the principal of this Note at
any time and may reborrow some or all of the principal, each as provided in the
Loan Agreement.

          10.  If Borrower fails to make any payment of interest within fifteen
(15) days after it becomes due and payable, Borrower agrees to pay interest on
                                                                            --
the late interest payment at an annual rate (the "Default Rate") of three
-------------------------
percent (3%) in excess of the Prime-based Rate, as defined in attached Exhibit
A, from the date the payment

                                      -2-
<PAGE>

becomes due until the date Borrower pays in full all accrued and unpaid interest
due under this Note.

          11.  If any of the following "Events of Default" occur, any obligation
of Lender to make advances under this Note shall terminate, and Bank in its sole
discretion shall notify Borrower, that all sums of principal and interest of and
on this Note shall become immediately due and payable without notice of default,
presentment or demand for payment, protest or notice of nonpayment or dishonor,
or other notices or demands of any kind or character:

               (a) Borrower fails to perform any obligation under this Note to
     pay principal and does not cure that failure within three (3) days after
     the date when due; or

               (b) Borrower fails to perform any obligation under this Note to
     pay interest and does not cure that failure within fifteen (15) days after
     the date when due; or

               (c) Borrower fails to perform any other obligation under this
     Note to pay money, and does not cure that failure within fifteen (15) days
     after written notice given by Bank; or

               (d) Under any other Loan Document, an Event of Default (as
     defined in that Loan Document) occurs.

          12.  It shall be an "Event of Default" under this Note if Borrower
becomes the subject of any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding"), where such proceeding is not dismissed
within sixty (60) days of commencement.  If that happens, any provision relating
to the holder's obligation to make advances under this Note shall terminate, and
all sums of principal and interest under this Note shall automatically become
immediately due and payable without notice of default, presentment or demand for
payment, protest or notice of nonpayment or dishonor, or other notices or
demands of any kind or character.

          13.  All amounts payable under this Note are payable in lawful money
of the United States no later than 10:00 a.m., San Francisco time, on the
Banking Day (as defined in attached Exhibit A) when due.  Checks constitute
payment only when collected.

          14.  Borrower understands and acknowledges that Bank may incur costs
on account of legal or regulatory requirements to maintain capital against the
Loan or a class of loans to which the Loan belongs.  Such costs may arise from
present

                                      -3-
<PAGE>

or future capital adequacy requirements which may be imposed on Bank or any
corporation controlling Bank, or from compliance by Bank or the corporation with
a directive, requirement or request from a governmental or regulatory agency,
whether or not having the force of law. From time to time upon sixty (60) days
notice by Bank, Borrower shall pay Bank for Borrower's allocable share of such
costs. Such costs shall be allocated to the Loan by Bank, using any reasonable
attribution method which Bank in the exercise of its reasonable judgment may
deem appropriate. From time to time, Bank shall submit to Borrower a certificate
setting forth Bank's determination of any amounts payable under this Section,
which shall be conclusive and binding in the absence of manifest error.

          15.  If any lawsuit, reference or arbitration is commenced which
arises out of, or which relates to, this Note, the Loan Documents or the Loan,
each prevailing party shall be entitled to recover from each other party such
sums as the court, referee or arbitrator may adjudge to be reasonable attorneys'
fees in the action, reference or arbitration, in addition to costs and expenses
otherwise allowed by law.  In all other situations, including any matter arising
out of or relating to any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships, Borrower agrees to pay all costs and expenses, including
attorneys' fees, which may be incurred in enforcing or protecting the rights or
interests of Bank.  From the time(s) incurred until paid in full to Bank, all
such sums shall bear interest at the Default Rate.

          16.  Whenever Borrower is obligated to pay or reimburse Bank for any
attorneys' fees, those fees shall include the allocated costs for services of
in-house counsel.

          17.  This Note is governed by the laws of the State of California,
without regard to the choice of law rules of that State.

          18.  If Bank delays in exercising or fails to exercise any of its
rights under this Note, that delay or failure shall not constitute a waiver of
any of Bank's rights, or any breach of this Note, or any default or failure of
condition under this Note.  No waiver by Bank of any of its rights, or any
breach of this Note, or any default or failure of condition under this Note
shall be effective, unless the waiver is expressly stated in a writing signed by
Bank.  All of Bank's remedies in connection with this Note or under applicable
law shall be cumulative, and Bank's exercise of any one or more of those
remedies shall not constitute an election of remedies.

          19.  This Note inures to and binds the heirs, legal representatives,
successors and assigns of Borrower and Bank; provided, however, that Borrower
may not assign this Note or any Loan funds, or assign or delegate any of its
rights or obligations, without the prior written consent of Bank in each
instance.  Bank in its

                                      -4-
<PAGE>

sole discretion may sell or assign participations or other interests in all or
part of the Loan on the terms and subject to the conditions of the Loan
Documents, all without notice to or the consent of Borrower. Without notice to
or the consent of Borrower, Bank may disclose any financial or other
information, data or material in Bank's possession relating to Borrower, the
Loan or the Property, including any improvements on it, to any actual or
prospective purchaser of any securities issued or to be issued by Bank, and to
any actual or prospective purchaser or assignee from Bank of any participation
or other interest in this Note or the Loan or any other loans made by Bank to
Borrower (whether evidenced by this Note or otherwise). If Bank so requests,
Borrower shall sign and deliver a new note or notes to be issued in exchange for
this Note.

          20.  As used in this Note, the word "include(s)" means "include(s),
without limitation," and the word "including" means "including, but not limited
to."  Exhibit is attached to this Note and is incorporated in this Note by this
reference.

          21.  Borrower and Borrower's general partner shall be jointly and
severally liable to Bank for Borrower's obligations under this Note.

          22.  Borrower has caused this Note to be executed by its general
partner, which has caused it to be executed by its officers, who were duly
authorized by the Board of Directors.

     1.   Interest Rate
          -------------

          (a) The Loan shall bear interest at the Bank's "Prime-based Rate"
equal to the Bank's Prime Rate plus:  (A) twenty-five one-hundredth's percent
(.25%) per year if the Borrower's Credit Rating (as defined below) is not rated
by a nationally recognized Rating Agency (as defined below) approved by Bank or
if any rating or part of a split rating is lower than BBB-/Baa3 and Borrower's
Leverage Ratio (as defined below) is greater than forty-five percent (45%); or
(B) zero percent (0%) per year for all other Borrower credit ratings and
Leverage Ratios (each, an "Applicable Prime Rate Margin").

The terms used above are defined in Section 2 of this Exhibit A.

          (b) The Prime-based Rate is a variable rate.

          (c) Borrower shall provide Bank with written evidence of its
investment grade Credit Rating from the Rating Agencies on an annual basis,
which written evidence must be acceptable to Bank in its sole discretion.  In
the event that there is a difference in Borrower's Credit Rating received from
such Rating Agencies, the lower Credit Rating shall prevail for purposes of
determining the Applicable Prime Rate Margin.

          (d) The Applicable Prime Rate Margin shall be effective on the first
day following the date that one or both Rating Agencies change the Borrower's
Credit Rating.

               "Prime Rate" means the rate of interest publicly announced from
time to time by Bank at its offices located in Charlotte, North Carolina, as its
Prime Rate. The Prime Rate is set by Bank based on various factors, including
Bank's costs and desired return, general economic conditions and other factors,
and is used as a reference point for pricing some loans. Bank may price loans to
its customers at, above, or below the Prime Rate. Any change in the Prime Rate
shall take effect at the opening of business on the day specified in the public
announcement of such change.

          (b)  Leverage Ratio
               --------------

               "Leverage Ratio" means, as of any date of determination, the
ratio of (a) Total Liabilities as of such date to (b) Gross Asset Value as of
such date, each as defined in the Loan Agreement.

          (c)  Credit Rating; Rating Agency
               ----------------------------

               -------------------------
not be in amounts less than Five Hundred Thousand Dollars ($500,000).

     3.   Calculation and Payment of Interest
          -----------------------------------

          Interest shall be calculated on the basis of a 360-day year and actual
days elapsed, which results in more interest than if a 365-day year were used.
Interest shall be payable on the first day of each month in arrears.

     4.   Additional Definitions
          ----------------------

          All capitalized terms used in this Exhibit A without definition shall

attached Exhibit A.  All principal and all accrued and unpaid interest shall be
due and payable no later than May 16, 2002, unless the term of the Loan is
extended as provided in Section 2.2 of the Loan Agreement, in which case all
                        -----------
principal and unpaid interest shall be paid on the extended Expiration Date.

          7.   Bank shall not be required to make any advance if to do so would
cause the Total Amount Outstanding under this Note to exceed the Available
Amount (as those terms are defined in the Loan Agreement).

          8.   Telefax Authorization
               ---------------------

               (a)  Bank may honor telefax instructions from John D. Eudy, Keith
R. Guericke, Michael J. Schall, Mark J. Mikl or Jordan E. Ritter for advances or
repayments or for designation of optional interest rates described in the Note
given by

                                      -2-
<PAGE>

any one of the individuals authorized to sign loan agreements on behalf of
Borrower, or any other individual designated by any one of such authorized
signers.

          (b)  Advances and repayments will be either (i) deposited in and
repayments will be withdrawn from Borrower's account number 14228-02371, or such
other of Borrower's accounts with Bank as designated in writing by Borrower, or
(ii) wire transferred at Borrower's written direction, telefaxed as set forth in
the Loan Agreement.

          9.   Borrower may prepay some or all of the principal of this Note at
any time, as provided in attached Exhibit B, and may reborrow some or all of the
principal as provided in the Loan Agreement.

          10.  If Borrower fails to make any payment of interest within fifteen
(15) days after it becomes due and payable, Borrower agrees to pay interest on
                                                                            --
the late interest payment at an annual rate (the "Default Rate") of three
-------------------------
percent (3%) in excess of the Prime-based Rate, as defined in attached Exhibit
A, from the date the payment becomes due until the date Borrower pays in full
all accrued and unpaid interest due under this Note.

          11.  (i) Upon any draw upon a Letter of Credit, any amount advanced
under such Letter of Credit until repaid, and (ii) from and after maturity of
this Note, whether upon scheduled maturity, by acceleration or otherwise, all
sums then due and payable under this Note, including all principal and all
accrued and unpaid interest, shall bear interest until paid in full at an annual
rate equal to the Default Rate plus the higher of (i) the Prime-based Rate or
(ii) the interest rate that would otherwise be applicable under the provisions
of attached Exhibit A; provided, however, that if at the time of maturity
different portions of the Loan are bearing interest at different rates in
accordance with attached Exhibit A, the Default Rate shall be calculated
separately as provided above with respect to each Rate Portion and with respect
to any portion of the Loan then bearing interest at the Prime-based Rate.

          12.  If any of the following "Events of Default" occur, any obligation
of Lender to make advances under this Note shall terminate, and Bank in its sole
discretion shall notify Borrower, that all sums of principal and interest of and
on this Note shall become immediately due and payable without notice of default,
presentment or demand for payment, protest or notice of nonpayment or dishonor,
or other notices or demands of any kind or character:

               (a)  Borrower fails to perform any obligation under this Note to
     pay principal or interest, and does not cure that failure within fifteen
     (15) days after the date when due; or

                                      -3-
<PAGE>

               (b)  Borrower fails to perform any other obligation under this
     Note to pay money, and does not cure that failure within fifteen (15) days
     after written notice given by Bank; or

               (c)  Under any other Loan Document, an Event of Default (as
     defined in that Loan Document) occurs.

          13.  It shall be an "Event of Default" under this Note if Borrower
becomes the subject of any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding"), where such proceeding is not dismissed
within sixty (60) days of commencement.  If that happens, any obligation of the
holder to make advances under this Note and any right of Borrower to designate
an interest rate other than the Prime-based Rate shall terminate, and all sums
of principal and interest under this Note shall automatically become immediately
due and payable without notice of default, presentment or demand for payment,
protest or notice of nonpayment or dishonor, or other notices or demands of any
kind or character.

          14.  All amounts payable under this Note are payable in lawful money
of the United States no later than 10:00 a.m., San Francisco time, on the
Banking Day (as defined in attached Exhibit A) when due.  Checks constitute
payment only when collected.

          15.  Borrower understands and acknowledges that Bank may incur costs
on account of legal or regulatory requirements to maintain capital against the
Loan or a class of loans to which the Loan belongs.  Such costs may arise from
present or future capital adequacy requirements which may be imposed on Bank or
any corporation controlling Bank, or from compliance by Bank or the corporation
with a directive, requirement or request from a governmental or regulatory
agency, whether or not having the force of law.  From time to time upon sixty
(60) days notice by Bank, Borrower shall pay Bank for Borrower's allocable share
of such costs.  Such costs shall be allocated to the Loan by Bank, using any
reasonable attribution method which Bank in the exercise of its reasonable
judgment may deem appropriate.  From time to time, Bank shall submit to Borrower
a certificate setting forth Bank's determination of any amounts payable under
this Section, which shall be conclusive and binding in the absence of manifest
error.

          16.  If any lawsuit, reference or arbitration is commenced which
arises out of, or which relates to, this Note, the Loan Documents or the Loan,
each prevailing party shall be entitled to recover from each other party such
sums as the court, referee or arbitrator may adjudge to be reasonable attorneys'
fees in the action, reference or arbitration, in addition to costs and expenses
otherwise allowed by law.  In all other situations, including any matter arising
out of or relating to any bankruptcy or other

                                      -4-
<PAGE>

voluntary or involuntary proceeding, in or out of court, for the adjustment of
debtor-creditor relationships, Borrower agrees to pay all costs and expenses,
including attorneys' fees, which may be incurred in enforcing or protecting the
rights or interests of Bank. From the time(s) incurred until paid in full to
Bank, all such sums shall bear interest at the Default Rate.

          17.  Whenever Borrower is obligated to pay or reimburse Bank for any
attorneys' fees, those fees shall include the allocated costs for services of
in-house counsel.

          18.  This Note is governed by the laws of the State of California,
without regard to the choice of law rules of that State.

          19.  If Bank delays in exercising or fails to exercise any of its
rights under this Note, that delay or failure shall not constitute a waiver of
any of Bank's rights, or any breach of this Note, or any default or failure of
condition under this Note.  No waiver by Bank of any of its rights, or any
breach of this Note, or any default or failure of condition under this Note
shall be effective, unless the waiver is expressly stated in a writing signed by
Bank.  All of Bank's remedies in connection with this Note or under applicable
law shall be cumulative, and Bank's exercise of any one or more of those
remedies shall not constitute an election of remedies.

          20.  This Note inures to and binds the heirs, legal representatives,
successors and assigns of Borrower and Bank; provided, however, that Borrower
may not assign this Note or any Loan funds, or assign or delegate any of its
rights or obligations, without the prior written consent of Bank in each
instance.  Bank in its sole discretion may sell or assign participations or
other interests in all or part of the Loan on the terms and subject to the
conditions of the Loan Documents, all without notice to or the consent of
Borrower.  Without notice to or the consent of Borrower, Bank may disclose any
financial or other information, data or material in Bank's possession relating
to Borrower, the Loan or the Property, including any improvements on it, to any
actual or prospective purchaser of any securities issued or to be issued by
Bank, and to any actual or prospective purchaser or assignee from Bank of any
participation or other interest in this Note or the Loan or any other loans made
by Bank to Borrower (whether evidenced by this Note or otherwise).  If Bank so
requests, Borrower shall sign and deliver a new note or notes to be issued in
exchange for this Note.

          21.  As used in this Note, the word "include(s)" means "include(s),
without limitation," and the word "including" means "including, but not limited
to."  Exhibits A and B are attached to this Note and are incorporated in this
Note by this reference.

                                      -5-

          22.  Borrower and Borrower's general partner shall be jointly and
severally liable to Bank for Borrower's obligations under this Note.

          24.  Borrower has caused this Note to be executed by its general
partner, which has caused it to be executed by its officers, who were duly
authorized by the Board of Directors.

                               PAYMENT GUARANTY
                               (Revolving Loan)

          This Payment Guaranty ("Guaranty") is dated as of May 16, 2000, by
ESSEX PROPERTY TRUST, INC., a Maryland corporation ("Guarantor"), in favor of
---------------------------
Bank of America, N.A. ("Bank").
---------------------

                              Factual Background
                              ------------------

     A.   Guarantor is executing this Guaranty to induce Bank among other things
to amend and restate a revolving loan (defined in Section 2 as the "Loan") that
has been made to Essex Portfolio, L.P., a California limited partnership
("Borrower"), in the principal amount of One Hundred Twenty Million and
No/100ths Dollars ($120,000,000.00). The Loan is being amended and restated
under that certain First Amended and Restated Revolving Loan Agreement (the
"Loan Agreement") dated as of even date herewith, between Bank and Borrower.

     B.   The Loan may be secured in part, as more fully explained in the Loan
Agreement.

     C.   This Guaranty renews that certain payment guaranty, dated as of May
11, 1998, and reconfirms all of Guarantor's obligations thereunder.

     D.   This Guaranty is one of several Loan Documents, as defined and
designated in the Loan Agreement. The Loan Documents also include the Loan
Agreement and certain other specified instruments and agreements.

                                   Guaranty
                                   --------

     1.   Guaranty of Loan. Guarantor unconditionally guaranties to Bank the
          ----------------
full payment of the Loan, and unconditionally agrees to pay Bank the full amount
of the Loan. This is a guaranty of payment, not of collection. If Borrower
defaults in the payment when due of all or any part of the Loan, Guarantor shall
in lawful money of the United States pay to Bank or order, on demand, all sums
due and owing on the Loan, including all interest, charges, fees and other sums,
costs and expenses.

     2.   Loan.  In this Guaranty, the term "Loan" is broadly defined to mean
          ----
and include all primary, secondary, direct, indirect, fixed and contingent
obligations of Borrower to pay principal, interest, prepayment charges, late
charges, loan fees and any other fees, charges, sums, costs and expenses which
may be owing at any time under the Loan Documents, as any or all of them may
from time to time be modified, amended, extended or renewed.  For purposes of
this Guaranty, the Loan includes any and all such obligations which may arise in
connection with any interest rate swaps or other transactions between Borrower
and Bank which may afford interest rate protection to all or part of the Loan.
If the amount outstanding under the Loan is determined by a court of competent
jurisdiction, that determination shall be conclusive and binding on Guarantor,
regardless of whether or not Guarantor was a party to the proceeding in which
the determination was made.

     3.   Rights of Bank.  Guarantor authorizes Bank to perform any or all of
          --------------
the following acts at any time in its sole discretion, all without notice to
Guarantor and without affecting Guarantor's obligations under this Guaranty:

                                      -1-
<PAGE>

          (a)  Bank may alter any terms of the Loan or any part of it, including
renewing, compromising, extending or accelerating, or otherwise changing the
time for payment of, or increasing or decreasing the rate of interest on, the
Loan or any part of it.

          (b)  Bank may take and hold security for the Loan or this Guaranty,
accept additional or substituted security for either, and subordinate, exchange,
enforce, waive, release, compromise, fail to perfect and sell or otherwise
dispose of any such security.

          (c)  Bank may direct the order and manner of any sale of all or any
part of any security now or later to be held for the Loan or this Guaranty, and
Bank may also bid at any such sale.

          (d)  Bank may apply any payments or recoveries from Borrower,
Guarantor or any other source, and any proceeds of any security, to Borrower's
obligations under the Loan Documents in such manner, order and priority as Bank
may elect, whether or not those obligations are guarantied by this Guaranty or
secured at the time of the application.

          (e)  Bank may release Borrower of its liability for the Loan or any
part of it.


          (f)  Bank may substitute, add or release any one or more guarantors or
endorsers.

          (g)  In addition to the Loan, Bank may extend other credit to
Borrower, and may take and hold security for the credit so extended, all without
affecting Guarantor's liability under this Guaranty.

     4.   Guaranty to be Absolute.  Guarantor expressly agrees that until the
          -----------------------
Loan is paid and performed in full and each and every term, covenant and
condition of this Guaranty is fully performed, Guarantor shall not be released
by or because of:

          (a)  Any act or event which might otherwise discharge, reduce, limit
or modify Guarantor's obligations under this Guaranty;

          (b)  Any waiver, extension, modification, forbearance, delay or other
act or omission of Bank, or its failure to proceed promptly or otherwise as
against Borrower, Guarantor or any security;

          (c)  Any action, omission or circumstance which might increase the
likelihood that Guarantor may be called upon to perform under this Guaranty or
which might affect the rights or remedies of Guarantor as against Borrower;

          (d)  Any dealings occurring at any time between Borrower and Bank,
whether relating to the Loan or otherwise; or

          (e)  Any action of Bank described in Section 3 above.

          Guarantor hereby acknowledges that absent this Section 4, Guarantor
might have a defense to the enforcement of this Guaranty as a result of one or
more of the foregoing acts, omissions, agreement, waivers or matters. Guarantor
hereby expressly waives and surrenders any defense to any liability under this
Guaranty based upon any of such acts, omissions, agreements, waivers or matters.
It is the express intent of Guarantor that Guarantor's obligations under this
Guaranty are and shall be absolute, unconditional and irrevocable.

                                      -2-
<PAGE>

     5.   Guarantor's Waivers.  Guarantor waives:
          -------------------

          (a)  All statutes of limitations as a defense to any action or
proceeding brought against Guarantor by Bank, to the fullest extent permitted by
law;

          (b)  Any right it may have to require Bank to proceed against
Borrower, proceed against or exhaust any security held from Borrower, or pursue
any other remedy in Bank's power to pursue;

          (c)  Any defense based on any claim that Guarantor's obligations
exceed or are more burdensome than those of Borrower;

          (d)  Any defense based on: (i) any legal disability of Borrower, (ii)
any release, discharge, modification, impairment or limitation of the liability
of Borrower to Bank from any cause, whether consented to by Bank or arising by
operation of law or from any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding") and (iii) any rejection or disaffirmance
of the Loan, or any part of it, or any security held for it, in any such
Insolvency Proceeding;

          (e)  Any defense based on any action taken or omitted by Bank in any
Insolvency Proceeding involving Borrower, including any election to have Bank's
claim allowed as being secured, partially secured or unsecured, any extension of
credit by Bank to Borrower in any Insolvency Proceeding, and the taking and
holding by Bank of any security for any such extension of credit;

          (f)  All presentments, demands for performance, notices of
nonperformance, protests, notices of protest, notices of dishonor, notices of
acceptance of this Guaranty and of the existence, creation, or incurring of new
or additional indebtedness, and demands and notices of every kind except for any
demand or notice by Bank to Guarantor expressly provided for in Section 1;

          (g)  Any defense based on or arising out of any defense that Borrower
may have to the payment or performance of the Loan or any part of it; and

          (h)  Any defense based on or arising out of any action of Bank
described in Sections 3 or 4 above.

     6.   Waivers of Subrogation and Other Rights and Defenses.
          ----------------------------------------------------

          (a)  Upon a default by Borrower, Bank in its sole discretion, without
prior notice to or consent of Guarantor, may elect to: (i) foreclose either
judicially or nonjudicially against any real or personal property security it
may hold for the Loan, (ii) accept a transfer of any such security in lieu of
foreclosure, (iii) compromise or adjust the Loan or any part of it or make any
other accommodation with Borrower or Guarantor, or (iv) exercise any other
remedy against Borrower or any security. No such action by Bank shall release or
limit the liability of Guarantor, who shall remain liable under this Guaranty
after the action, even if the effect of the action is to deprive Guarantor of
any subrogation rights, rights of indemnity, or other rights to collect
reimbursement from Borrower for any sums paid to Bank, whether contractual or
arising by operation of law or otherwise. Guarantor expressly agrees that under
no circumstances shall it be deemed to have any right, title, interest or claim
in or to any real or personal property to be held by Bank or any third party
after any foreclosure or transfer in lieu of foreclosure of any security for the
Loan.

                                      -3-
<PAGE>

          (b)  Regardless of whether Guarantor may have made any payments to
Bank, Guarantor forever waives: (i) all rights of subrogation, all rights of
indemnity, and any other rights to collect reimbursement from Borrower for any
sums paid to Bank, whether contractual or arising by operation of law (including
the United States Bankruptcy Code or any successor or similar statute) or
otherwise, (ii) all rights to participate in any security now or later to be
held by Bank for the Loan, and (iii) all rights to enforce any remedy that Bank
may have against Borrower.

          (c)  Guarantor waives the Guarantor's rights of subrogation and
reimbursement and any other rights and defenses available to the Guarantor by
reason of Sections 2787 to 2855, inclusive, of the California Civil Code
including, without limitation, any defenses the Guarantor may have to the
Guaranty obligation by reason of an election of remedies by Bank.

          (d)  Guarantor waives all right and defenses arising out of an
election of remedies by Bank, even though that election of remedies has
destroyed the Guarantor's rights of subrogation and reimbursement against the
Borrower.

          (e)  No provision or waiver in this Guaranty shall be construed as
limiting the generality of any other waiver contained in this Guaranty.

     7.   Revival and Reinstatement.  If Bank is required to pay, return or
          -------------------------
restore to Borrower or any other person any amounts previously paid on the Loan
because of any Insolvency Proceeding of Borrower, any stop notice or any other
reason, the obligations of Guarantor shall be reinstated and revived and the
rights of Bank shall continue with regard to such amounts, all as though they
had never been paid.

     8.   Information Regarding Borrower and the Property.  Before signing this
          -----------------------------------------------
Guaranty, Guarantor investigated the financial condition and business operations
of Borrower, the present and former condition, uses and ownership of the
Property, and such other matters as Guarantor deemed appropriate to assure
itself of Borrower's ability to discharge its obligations under the Loan
Documents.  Guarantor assumes full responsibility for that due diligence, as
well as for keeping informed of all matters which may affect Borrower's ability
to pay and perform its obligations to Bank.  Bank has no duty to disclose to
Guarantor any information which Bank may have or receive about Borrower's
financial condition or business operations, or any other circumstances bearing
on Borrower's ability to perform.

     9.   Subordination.  Any rights of Guarantor, whether now existing or later
          -------------
arising, to receive payment on account of any indebtedness (including interest)
owed to it by Borrower, or to withdraw capital invested by it in Borrower, or to
receive distributions from Borrower, shall at all times be subordinate as to
lien and time of payment and in all other respects to the full and prior
repayment to Bank of the Loan.  Guarantor shall not be entitled to enforce or
receive payment of any sums hereby subordinated until the Loan has been paid and
performed in full and any such sums received in violation of this Guaranty shall
be received by Guarantor in trust for Bank.  The foregoing notwithstanding,
Guarantor is not prohibited from receiving (a) such reasonable management fees
or reasonable salary from Borrower as Bank may find acceptable from time to
time,  (b) distributions from Borrower in an amount equal to any income taxes
imposed on Guarantor which are attributable to Borrower's income from any
property owned by Borrower, and (c) distributions made in the ordinary course of
Guarantor's business, which distributions do not exceed ninety-five (95%) of

                                      -4-
<PAGE>

Funds From Operations during any period where there is no Event of Default
hereunder or under any Loan Document; provided, however, that if Essex
Portfolio, L.P. distributes or pays amounts in excess of ninety-five percent
(95%) of Funds From Operations during any fiscal year, it shall not be a default
under this provision if, when taken together with all distributions and payments
during the next ensuing six (6) month period, the distributions and payments for
the eighteen (18) month period then ended are less than ninety-five percent
(95%) of Funds From Operations. "Funds From Operations" has the meaning given to
it in Section 7.13 of the Loan Agreement. Notwithstanding the above, Guarantor
and/or Borrower may make any distributions which are necessary for Guarantor to
continue to qualify as a REIT as that term is defined in Section 11(b) of this
Guaranty.

     10.  Guarantor's Representations and Warranties.  Guarantor represents and
          ------------------------------------------
warrants that:

          (a)  Financial Statements True and Correct.  All financial statements
               -------------------------------------
and other financial information furnished or to be furnished to Bank are or will

otherwise provided for herein and do or will fairly represent the financial
condition of Guarantor (including all contingent liabilities) (for purposes of
this Section 10(a), the term "material respects" means any variance in the
aggregate amount of $1,000,000.00);

          (b)  Financial Statements According to GAAP. All financial statements
               --------------------------------------
were or will be prepared in accordance with generally accepted accounting

          (c)  No Material Adverse Change.  There has been no material adverse
               --------------------------
change in Guarantor's financial condition since the dates of the statements most
recently furnished to Bank.

          (d)  Organization of Borrower.  Guarantor is a corporation duly

          (e)  Authorization.  This Guaranty is within Guarantor's powers, has
               -------------
been duly authorized, and does not conflict with any of its organizational
papers.

          (f)  Enforceable Agreement. This Agreement is a legal, valid and
               ---------------------
binding agreement of Guarantor, enforceable against Guarantor in accordance with
its terms, and any other Loan Document to which Guarantor is a party, when
executed and delivered, will be similarly legal, valid, binding and enforceable,
except to the extent that the enforcement of the rights and remedies of Bank may
hereafter be subject to bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting generally the enforcement of creditors' rights and
remedies, and the availability of equitable remedies may be subject to the
discretion of the court before which any proceeding thereof is brought.

          (g)  Good Standing.  In each state in which Guarantor does business,
               -------------

with fictitious name statutes.

          (h)  No Conflicts.  Guarantor, to the best of its knowledge, is not
               ------------
in violation of, nor do the terms of this Agreement or any other Loan Document
conflict with, any regulation or ordinance, any order of any court or
governmental entity, or any covenant or agreement affecting Guarantor.

                                      -5-
<PAGE>

          (i)  Lawsuits. There is no lawsuit, tax claim or other dispute
               --------
pending or threatened against Guarantor which, if lost, would materially
adversely impair Guarantor's financial condition or ability to repay the Loan.

     11.  Affirmative Covenants.   Guarantor promises to keep each of the
          ---------------------
following covenants:

          (a)  Compliance with Law.
               -------------------

          Guarantor shall comply with all existing and future laws (including

     14.  Reference and Arbitration.
          -------------------------

          (a)  Judicial Reference.  In any judicial action between or among the
               ------------------
parties, including any action or cause of action arising out of or relating to
this Guaranty or the Loan Documents or based on or arising from an alleged tort,
all decisions of fact and law shall at the request of any party be referred to a
referee in accordance with California Code of Civil Procedure Sections 638 et
                                                                           --
seq. The parties shall designate to the court a referee or referees
---
selected under the auspices of the American Arbitration Association ("AAA") in
the same manner as arbitrators are selected in AAA-sponsored proceedings. The
presiding referee of the panel, or the referee if there is a single referee,
shall be an active attorney or retired judge. Judgment upon the award rendered
by such referee or referees shall be entered in the court in which such
proceeding was commenced in accordance with California Code of Civil Procedure
Sections 644 and 645.

          (b)  Mandatory Arbitration.  Any controversy or claim between or
               ---------------------
among the parties, including those arising out of or relating to this Guaranty
or the Loan Documents and any claim based on or arising from an alleged tort,
shall at the request of any party be determined by arbitration. The arbitration
shall be conducted in accordance with the United States Arbitration Act (Title
9, U.S. Code), notwithstanding any choice of law provision in this Guaranty, and
under the Commercial Rules of the AAA. The arbitrator(s) shall give effect to
statutes of limitation in determining any claim. Any controversy concerning
whether an issue is arbitrable shall be determined by the arbitrator(s).
Judgment upon the arbitration award may be entered in any court having
jurisdiction. The institution and maintenance of an action for judicial relief
or pursuit of a provisional or ancillary remedy shall not constitute a waiver of
the right of any party, including the plaintiff, to submit the controversy or
claim to arbitration if any other party contests such action for judicial
relief.

          (c)  Provisional Remedies, Self-Help and Foreclosure.  No provision
               -----------------------------------------------
of this Section 14 shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, if any, or to obtain provisional or ancillary
remedies from a court of competent jurisdiction before, after, or during the
pendency of any arbitration or other proceeding. The exercise of a remedy does
not waive the right of either party to resort to arbitration or reference.

     15.  Authorization; No Violation.  Guarantor is authorized to execute,
          ---------------------------
deliver and perform under this Guaranty, which is a valid and binding obligation
of Guarantor, except as the same may be limited by insolvency, bankruptcy,
reorganization, or other laws relating to or affecting the enforcement of
creditors' rights or by general equitable principles. No provision or

                                      -9-
<PAGE>

obligation of Guarantor contained in this Guaranty violates any applicable law,
regulation or ordinance, or any order or ruling of any court or governmental
agency. No such provision or obligation conflicts with, or constitutes a breach
or default under, any agreement to which Guarantor is a party. No consent,
approval or authorization of or notice to any person or entity is required in
connection with Guarantor's execution of and obligations under this Guaranty.

     16.  Additional and Independent Obligations.  Guarantor's obligations
          --------------------------------------
under this Guaranty are in addition to its obligations under any other existing
or future guaranties, each of which shall remain in full force and effect until
it is expressly modified or released in a writing signed by Bank. Guarantor's
obligations under this Guaranty are independent of those of Borrower on the
Loan. Bank may bring a separate action, or commence a separate reference or
arbitration proceeding against Guarantor without first proceeding against
Borrower, any other person or any security that Bank may hold, and without
pursuing any other remedy. Bank's rights under this Guaranty shall not be
exhausted by any action by Bank until the Loan has been paid and performed in
full.

     17.  No Waiver; Consents; Cumulative Remedies.  Each waiver by Bank must
          ----------------------------------------
be in writing, and no waiver shall be construed as a continuing waiver. No
waiver shall be implied from Bank's delay in exercising or failure to exercise
any right or remedy against Borrower, Guarantor or any security. Consent by Bank
to any act or omission by Borrower or Guarantor shall not be construed as a
consent to any other or subsequent act or omission, or as a waiver of the
requirement for Bank's consent to be obtained in any future or other instance.
All remedies of Bank against Borrower and Guarantor are cumulative.

     18.  No Release.  Guarantor shall not be released from its obligations
          ----------
under this Guaranty except by a writing signed by Bank.

     19.  Heirs, Successors and Assigns; Participations.  The terms of this
          ---------------------------------------------
Guaranty shall bind and benefit the heirs, legal representatives, successors and
assigns of Bank and Guarantor; provided, however, that Guarantor may not assign
this Guaranty, or assign or delegate any of its rights or obligations under this
Guaranty, without the prior written consent of Bank in each instance. Bank in
its sole discretion may sell, syndicate or assign participations or other
interests in the Loan and this Guaranty, in whole or in part, all without notice
to or the consent of Guarantor and without affecting Guarantor's obligations
under this Guaranty. Also without notice to or the consent of Guarantor, Bank
may disclose any and all information in its possession concerning Guarantor,
this Guaranty and any security for this Guaranty to any actual or prospective
purchaser of any securities issued or to be issued by Bank, and to any actual or
prospective purchaser or assignee of any participation or other interest in the
Loan and this Guaranty.

     20.  Notices.  All notices given under this Guaranty must be in writing and
          -------
shall be effectively served upon delivery, or if mailed, upon the first to occur
of receipt or the expiration of forty-eight hours after deposit in certified
United States mail, postage prepaid, sent to the party at its address given at
the end of this Guaranty.  Those addresses may be changed by Bank or Guarantor
by written notice to the other party.  Service of any notice on any one
Guarantor signing this Guaranty shall be effective service on Guarantor for all
purposes.

     21.  Rules of Construction.  In this Guaranty, the word "Borrower"
          ---------------------
includes both the named Borrower and any other person who at any time assumes or
otherwise becomes primarily liable for all or any part of the obligations of the
named Borrower on the Loan. The word "person" includes any individual, company,
trust or other legal entity of any kind. The word "include(s)" means
"include(s), without limitation," and the word "including" means "including,

                                     -10-
<PAGE>

but not limited to." When the context and construction so require, all words
used in the singular shall be deemed to have been used in the plural and vice
versa. No listing of specific instances, items or matters in any way limits the
scope or generality of any language of this Guaranty. All headings appearing in
this Guaranty are for convenience only and shall be disregarded in construing
this Guaranty.

     22.  Governing Law.  This Guaranty shall be governed by, and construed in
          -------------
accordance with, the laws of the State of California, without regard to any
choice of law principles.

     23.  Costs and Expenses.  If any lawsuit, reference or arbitration is
          ------------------
commenced which arises out of, or which relates to this Guaranty, the Loan
Documents or the Loan, the prevailing party shall be entitled to recover from
each other party such sums as the court, referee or arbitrator may adjudge to be
reasonable attorneys' fees (including allocated costs for services of in-house
counsel) in the action or proceeding, in addition to costs and expenses
otherwise allowed by law. In all other situations, including any Insolvency
Proceeding, Guarantor agrees to pay all of Bank's costs and expenses, including
reasonable attorneys' fees (including allocated costs for services of Bank's in-
house counsel) which may be incurred in any effort to collect or enforce the
Loan or any part of it or any term of this Guaranty. From the time(s) incurred
until paid in full to Bank, all sums shall bear interest at the Default Rate, as
defined in the Loan Agreement.

     24.  Consideration.  Guarantor acknowledges that it expects to benefit from
          -------------
Bank's extension of the Loan to Borrower because of its relationship to
Borrower, and that it is executing this Guaranty in consideration of that
anticipated benefit.

     25.  Integration; Modifications.  This Guaranty (a) integrates all the
          --------------------------
terms and conditions mentioned in or incidental to this Guaranty, (b) supersedes
all oral negotiations and prior writings with respect to its subject matter, and
(c) is intended by Guarantor and Bank as the final expression of the agreement
with respect to the terms and conditions set forth in this Guaranty and as the
complete and exclusive statement of the terms agreed to by Guarantor and Bank.
No representation, understanding, promise or condition shall be enforceable
against any party hereto unless it is contained in this Guaranty. This Guaranty
may not be modified except in a writing signed by both Bank and Guarantor. No
course of prior dealing, usage of trade, parol or extrinsic evidence of any
nature shall be used to supplement, modify or vary any of the terms hereof.

     26.  Miscellaneous.  The legal incapacity of any Guarantor shall not
          -------------
terminate the obligations of such Guarantor under this Guaranty, including its
obligations with regard to future advances under the Loan Documents. The
liability of all persons who are in any manner obligated under this Guaranty
shall be joint and several. The illegality or unenforceability of one or more
provisions of this Guaranty shall not affect any other provision. Time is of the
essence in the performance of this Guaranty by Guarantor.

                                     -11-
<PAGE>

     27.  Counsel:  Guarantor acknowledges that Guarantor has had adequate

Guarantor's choice prior to signing it.
