Re:    Limitations on Ownership of Stock of
       Essex Property Trust, Inc. (the "Company")
       -------------------------------------------

Gentlemen:

       In connection with the transactions contemplated by that certain Stock 
Purchase Agreement dated as of June 20, 1996, as amended (the "Stock Purchase 
Agreement"), between the Company and Tiger/Westbrook Real Estate Fund, L.P. 
and Tiger/Westbrook Real Estate Co-Investment Partnership, L.P. 
(collectively, together with any nominee or nominees in whose name securities 
may be held, "Buyer"), the Company has solicited and obtained the approval of 
the stockholders of the Company to an amendment to the charter of the Company 
(the "Charter") that makes certain modifications to the ownership limitations 
set forth in the Charter to, among other things, facilitate the transactions 
contemplated by the Stock Purchase Agreement (the "Charter Amendment").  The 
details of the Charter Amendment are more particularly described under 
Proposal 2 of the Proxy Statement of the Company dated September 5, 1996 (the 
"Proxy Statement"), prepared and submitted by the Company to its stockholders 
in preparation for the special meeting of the stockholders at which the 
stockholders of the Company approved, among other things, the Charter 
Amendment. 

       As more particularly set forth in the Proxy Statement, the Charter 
Amendment provides that the Board of Directors (as defined in the Charter) 
may exempt holders of the Company's Equity Stock (as defined in the Charter) 
(other than individuals for the purposes of Section 542(a)(2) of the Code 
[as defined in the Charter]) from the Ownership Limit or Existing Holder 
Limit (as both such terms are defined in the Charter) conditioned upon, among 
other things, the receipt by the Company of an opinion of counsel to the 
effect that such holder's exemption and Beneficial Ownership of Equity Stock 
(as such term is defined in the Charter) will not cause the Company to 
violate certain requirements of the Code for maintaining the Company as a 
real

estate investment trust ("REIT") under the Code (the "REIT Requirements").  
The Charter Amendment provides, in addition, that any exemption that would 
allow a holder to Beneficially Own or Constructively Own (as both such terms 
are defined in the Charter) shares of the Company's Equity Stock with an 
aggregate value that is greater than 25% of the value of the outstanding 
shares of stock of the Company (the "25% Limit") shall require a ruling (an 
"IRS Ruling") from the Internal Revenue Service ("IRS") authorizing such 
exemption, in addition to the other requirements of the Charter Amendment.

       The Company and the Buyer now wish to provide for certain obligations 
of the Company and the Buyer in connection with any request for an IRS Ruling 
made by any holder (other than the Buyer) pursuant to the Charter Amendment. 
Accordingly, the Company and the Buyer hereby agree as follows:

       1.   If in compliance with the requirements of the Charter Amendment, 
an IRS Ruling is required to be obtained with respect to the proposed 
acquisition (the "Proposed Acquisition") of Equity Stock by any stockholder 
or proposed stockholder of the Company (other than the Buyer or an affiliate 
of the Buyer) (the "Third Party"), the Company shall promptly notify (the 
"Company Notice") the Buyer in writing of the Proposed Acquisition.  The 
Company Notice shall (x) identify the Third Party and (y) set forth the 
maximum aggregate value of the Third Party's permitted Beneficial Ownership 
of Equity Stock (assuming completion of the Proposed Acquisition) as a 
percentage of the aggregate value of the outstanding shares of Equity Stock 
(as such percentage may be adjusted pursuant to paragraph 5 below, the 
"Holder Percentage Ownership Limit").  The Buyer shall have fifteen (15) 
business days after delivery of the Company Notice in which to notify the 
Company in writing (the "Election Notice") that the Buyer elects to cause a 
request to be made for the Buyer Ruling (as hereinafter defined) and to 
otherwise proceed to obtain an exemption from the Ownership Limit, in the 
manner described in the succeeding paragraphs, provided however, the Buyer 
shall have no rights, and the Company shall have no obligations, hereunder 
with regard to the Proposed Acquisition, unless, as of the date of delivery 
of the Election Notice, (a) if the average of the last reported sale prices 
per share of the Company's Common Stock (as defined in the Stock Purchase 
Agreement), as determined by the provisions of Section 5(e)(vii) of the 
Articles Supplementary, filed July 1, 1996, for the Company's 8.75% 
Convertible Preferred Stock, Series 1996A (the "Articles Supplementary"), on 
each of the ten (10) consecutive Trading Days (as defined in the Articles 
Supplementary) preceding the date on which the Buyer delivers the Election 
Notice (the "Average Closing Price") is equal to or less than $23.00, Buyer 
and those of its affiliates that are controlled by Westbrook Real Estate 
Partners, L.L.C., considered together as a whole (collectively, the "Buyer 
Entities"), hold no less than $10 million in value of such Common Stock 
(calculated by multiplying the number of shares of such Common Stock held by 
the Buyer Entities [assuming conversion of all shares of Preferred Stock 
(as defined in the Stock Purchase Agreement) held by the Buyer Entities 
into shares of such Common Stock at the Conversion Price (as defined in the 
Articles Supplementary)] by the Average Closing Price), or (b) if the Average 
Closing Price is greater than $23.00, the Buyer Entities hold no less than $25
million in value of such Common Stock (calculated by multiplying the number 
of shares of such Common Stock held by the Buyer 


October 21, 1996
Page 3


Entities [assuming conversion of all shares of Preferred Stock held by the 
Buyer Entities into shares of such Common Stock at the Conversion Price] by 
the Average Closing Price), provided that if, prior to June 20, 1997, such 
Average Closing Price is greater than $23.00, the value of the Common Stock 
held by the Buyer Entities shall be calculated as if Buyer purchased all 
1,600,000 shares of Preferred Stock contemplated to be purchased by Buyer 
under the Stock Purchase Agreement (excluding, however, any shares of 
Preferred Stock actually purchased by Buyer and subsequently transferred to 
any person or entity other than a Buyer Entity). In the event that the 
Company does not receive the Election Notice within the fifteen (15) business 
days prescribed by the preceding sentence, the Buyer shall be deemed to have 
irrevocably and forever waived all of its rights pursuant to this paragraph 
as to the Proposed Acquisition triggering the Election Notice (but not as to 
any future Proposed Acquisition).

       2.   If the Buyer makes the election described in the previous 
paragraph, the Company shall (a) promptly, but in no event later than the 
date on which the Buyer Ruling Request (as hereinafter defined) is filed, 
recommend to the Board of Directors that, conditioned upon the Company's 
receipt of the Buyer Ruling, an opinion of counsel and such undertakings and 
other items required by the Charter Amendment, and subject to the terms of 
this agreement, the Board of Directors issue an exemption from the Ownership 
Limit to the Buyer, increasing the Buyer's maximum permitted ownership of 
Equity Stock to the Holder Percentage Ownership Limit, as the same may be 
adjusted pursuant to paragraph 3 hereof and (b) file a request for a ruling 
from the IRS, authorizing the Buyer to own Equity Stock up to the Holder 
Percentage Ownership Limit (the "Buyer Ruling Request").  The Company shall 
file the Buyer Ruling Request concurrently with the request for a ruling from 
the IRS authorizing the Third Party to own Equity Stock up to the Holder 
Percentage Ownership Limit (the "Third Party Ruling Request"), provided that 
the Buyer shall (without limiting Buyer's cooperation obligations under 
paragraph 3 below) have provided all information it is required to provide 
for the Buyer Ruling Request and shall have approved the Buyer Ruling Request 
by the later of (a) the date that the Third Party Ruling Request is prepared 
to be filed or (b) fifteen (15) business days after the Company's receipt of 
the Election Notice.  The Company shall use to file the Buyer Ruling Request 
and obtain the IRS Ruling approving the Buyer Ruling Request, as the same may 
be modified pursuant to paragraph 5 below (the "Buyer Ruling"), the greater 
of (i) the efforts it is required by contract with the Third Party to file 
the Third Party Ruling Request and obtain the IRS Ruling approving the Third 
Party Ruling Request, as the same may be modified pursuant to paragraph 5 
below (the "Third Party Ruling"), and (ii) the actual efforts it uses to file 
the Third Party Ruling Request and obtain the Third Party Ruling. 
Notwithstanding the foregoing, the Buyer acknowledges and agrees that, 
subject to paragraph 5 below, (a) any failure to obtain the Buyer Ruling 
shall not affect the validity of the Third Party Ruling as to the Proposed 
Acquisition (if obtained) or delay, impair or otherwise affect, in any 
manner, the consummation of the Proposed Acquisition, and (b) any failure to 
obtain the Third Party Ruling shall not affect the validity of the Buyer 
Ruling (if obtained) or delay, impair or otherwise affect, in any manner, the 
purchase by the Buyer of any shares of Equity Stock permitted pursuant to the 
exemption under the Charter Amendment granted to the Buyer by the Board 
pursuant to the Buyer Ruling.  



October 21, 1996

       3.   Buyer agrees to promptly cooperate with the Company in its 
preparation of all documents required in connection with the Buyer Ruling 
Request and the obtainment of the Buyer Ruling, including, providing 
information as to the nature of Buyer's investors, provided that any 
representations required to be made by Buyer to the Company shall not differ 
materially from Buyer's August 1996 representations to the Company in 
connection with the Company's August 1996 IRS ruling request relating to 
Buyer and provided further that Buyer may refuse to provide information if it 
reasonably believes that doing so would be adverse to its interests.  
Notwithstanding, the foregoing, if the IRS requires Buyer to provide 
information or representations that Buyer is not required to provide pursuant 
to the previous sentence, and Buyer refuses to provide any such information 
or representations, the Company's obligation to file the Buyer Ruling Request 
and/or to obtain the Buyer Ruling shall immediately and automatically 
terminate.  The Company shall promptly provide the Buyer with copies of any 
and all correspondence and other items received from the IRS or delivered by 
the Company to the IRS in connection with the filing and processing of the 
Buyer Ruling Request (and, if and to the extent not limited or prohibited by 
any confidentiality arrangement between the Third Party and the Company, the 
Third Party Ruling Request).  Prior to any material communication with the 
IRS initiated by the Company in connection with the Buyer Ruling Request, the 
Company shall notify (orally or in writing) the Buyer of the reason for and 
the general nature of such communication.

       4.   If the Buyer Ruling is not obtained prior to the later of (a) the 
date which is six (6) months after the date on which the Company submits to 
the IRS the Buyer Ruling Request, (b) the date, if any, on or prior to which 
the Company has agreed with the Third Party to obtain the Third Party Ruling, 
or (c) if no such date has been agreed upon between the Company and the Third 
Party, the date on which (x) the Company withdraws the Third Party Ruling 
Request, (y) the date on which the Third Party Ruling is received by the 
Company or (z) the date on which the IRS denies or rejects the Third Party 
Ruling Request, the Company shall have no further obligation to obtain the 
Buyer Ruling and any and all rights of the Buyer with respect to the Buyer 
Ruling or with respect to the Proposed Acquisition (but not with respect to 
any future Proposed Acquisition) shall immediately and automatically 
terminate and be of no further force or effect and neither party shall have 
any further rights or obligations with respect thereto (other than the 
Company's and the Buyer's obligations under paragraph 10 below).

       5.   Notwithstanding anything to the contrary set forth in paragraph 2 
above, the Holder Percentage Ownership Limit shall be adjusted as follows:  
if the Third Party Ruling Request or the Buyer Ruling Request is, or both 
are, denied by the IRS or, if, with respect to the Third Party Ruling, the 
Buyer Ruling or both, the IRS approves an exemption from the Ownership Limit 
that is lower than the Holder Percentage Ownership Limit requested in the 
Third Party Ruling Request and/or the Buyer Ruling Request, in either case 
due in whole or in part (but for no other reason) to a determination by the 
IRS that the granting of both the requested Buyer Ruling, in full, and the 
requested Third Party Ruling, in full, could cause the Company to violate the 
REIT Requirements, the Holder Percentage Ownership Limit shall, at the option 
of Buyer (the "Buyer Option"), to be exercised no later than four (4) 
business days after Buyer's receipt of notice of



October 21, 1996
Page 5


such denial or determination by the IRS (provided that Buyer's failure to 
exercise the Buyer Option within such period shall constitute an election by 
Buyer not to exercise the Buyer Option), and if approved by the IRS, be 
reduced by the amount required by the IRS to grant the Third Party Ruling and 
the Buyer Ruling, such that the Holder Percentage Ownership Limit, as 
adjusted, does not permit any holder of Equity Stock to cause the Company to 
violate the REIT Requirements.  If Buyer timely exercises the Buyer Option, 
Buyer and the Company shall promptly and reasonably cooperate to 
appropriately amend the Buyer Ruling Request and to cause the Third Party 
Ruling Request to be amended, as necessary, and to provide all other 
documents, as and to the extent required by the IRS to issue the Third Party 
Ruling and the Buyer Ruling, in each case providing for the reduced Holder 
Percentage Ownership Limit. Notwithstanding the foregoing, if (a) the 
reduction in the Holder Percentage Ownership Limit is required due to the 
Buyer Ruling Request (or any documents or information provided to the IRS in 
connection therewith), including, without limitation, due to the ownership 
structure of Buyer or the nature of the beneficial owners of Buyer, (b) Buyer 
timely exercises the Buyer Option and the IRS approves that the Holder 
Percentage Ownership Limit as reduced, (c) pursuant to the terms of the 
Proposed Acquisition, the Third Party has a binding obligation to purchase 
Equity Stock from the Company (and not from a third party, pursuant to a 
private sale or purchases on the secondary market or otherwise), the amount 
of which Equity Stock is reduced (the value of the amount of Equity Stock 
subject to such reduction, the "Reduction Amount") due to the reduction in 
the Holder Percentage Ownership Limit, and (d) the Holder Percentage 
Ownership Limit (prior to any adjustment hereunder) was determined by the 
Company and the Third Party pursuant to a good faith expectation (assuming 
that no Buyer Ruling Request would be made) that the IRS would approve the 
Third Party Ruling without any adjustment hereunder; then, as and when such 
purchases would have been required by the Third Party pursuant to the 
Proposed Acquisition, the Buyer Entities shall, collectively, in the 
aggregate, purchase (on the secondary market or otherwise) shares of Equity 
Stock (either in the form of Common Stock or such other Equity Stock as 
mutually agreed upon between Buyer and the Company) equal in value to the 
Reduction Amount, provided, however, that the Buyer Entities' obligations to 
make such purchase shall be subject to the satisfaction (or waiver) of all 
conditions precedent to the Third Party's obligation to purchase all shares 
of Equity Stock required to be purchased by the Third Party pursuant to the 
Proposed Transaction (other than any condition relating to a reduction in the 
Holder Percentage Ownership Limit contemplated by this paragraph 5).  Buyer's 
failure to exercise the Buyer Option, as and when required by this paragraph 
5, shall immediately and automatically terminate Buyer's rights hereunder to 
obtain the Buyer Ruling with respect to the Proposed Acquisition, and 
thereupon, the Company may modify and/or resubmit the Third Party Ruling 
Request, in its entirety, and undertake any and all efforts to obtain the 
Third Party Ruling.

       6.   The exemption from the Ownership Limit granted to Buyer by the 
Board of Directors pursuant to paragraph 2 above, if granted, shall be on 
substantially the same terms and subject to the same restrictions, 
limitations and conditions (but no other restrictions, limitations or 
conditions) as the exemption granted to the Third Party by the Board of 
Directors, including, without limitation, as to minimum Equity Stock 
ownership requirements, if any, and the ability of the Board of Directors to 
revoke, limit or modify the exemption, if any, provided that (a)



October 21, 1996
Page 6


Buyer shall not be required to purchase any Equity Stock other than Common 
Stock, unless otherwise agreed by Buyer and the Company (it being understood 
that, if the exemption granted to the Third Party requires the purchase by 
the Third Party of any Equity Stock other than Common Stock or such exemption 
otherwise contains terms or conditions relating to Equity Stock other than 
Common Stock, unless otherwise agreed to by Buyer and the Company, the 
exemption granted to Buyer shall be adjusted to refer to equivalent values of 
Common Stock), and (b) such exemption shall not provide for Buyer's permitted 
Beneficial Ownership of Equity Stock to be reduced below that permitted by 
any previous exemption from the Ownership Limit granted to Buyer by the Board 
of Directors.

       7.  Without limiting the provisions of paragraph 6 above, if the terms 
of the Proposed Acquisition require the Third Party to purchase shares of 
Equity Stock in excess (the number of such excess shares, the "Excess") of 
the shares of Equity Stock required to raise the value of the Third Party's 
ownership of Equity Stock above the 25% Limit, on or prior to the later of 
(a) 270 days after the date of the Buyer Ruling, or (b) the date on which the 
Third Party is required to complete such purchase (as such date may be waived 
or extended by the Company and/or the Third Party), Buyer shall purchase 
shares of Common Stock (or such other Equity Stock as may be agreed by Buyer 
and the Company) equal in value to the Excess.  

       8.   The request for the Buyer Ruling and all documents and 
information required in connection therewith shall be in form and substance 
reasonably satisfactory to Buyer.  Subject to the confidentiality 
requirements of the stockholder or proposed stockholder subject to the 
Proposed Acquisition, the Company shall promptly provide to the Buyer copies 
of the Third Party Ruling Request.  

       9.   Nothing in this Agreement shall require the Company to sell 
shares of Equity Stock directly or indirectly to the Buyer (or provide to the 
Buyer any preemptive rights or options with respect to the same).  

       10.  If a Buyer Ruling is required by this Agreement, the Company 
shall prepare the Buyer Ruling and bear the costs it incurs in connection 
with the preparation, filing and obtainment of the Buyer Ruling.  As provided 
for in the Agreement, the Buyer may review the Buyer Ruling and it shall bear 
the costs it incurs in connection with such review (including, without 
limitation, the costs of any counsel and/or consultants it retains).  If 
either party hereto fails to perform any of its obligations under this 
Agreement or if a dispute arises between the parties hereto concerning the 
meaning or interpretation of any provision of this Agreement, then the 
defaulting party or the party not prevailing in such dispute shall pay any 
and all costs and expenses incurred by the other party on account of such 
default and/or in enforcing or establishing its rights hereunder, including, 
without limitation, court costs and reasonable attorneys' fees and 
disbursements.  Any such attorneys' fees and other expenses 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.

       11.   Without limiting any remedies of the Company, at law or in 
equity, Buyer's failure to purchase shares of Equity Stock pursuant to the 
terms of this Agreement, as and when required hereunder, shall cause this 
Agreement to immediately and automatically terminate and be of no further 
force or effect.

      12.   Time is of the essence with respect to the performance by each of 
the party's hereto of their respective obligations hereunder.

      13.   This agreement, incorporates by reference, as if specifically set 
forth herein, all of the provisions of Article 9 of the Stock Purchase 
Agreement, other than Sections 9.7, 9.11, 9.13 and 9.14 thereof.  As used in 
such Article 9, the term "Agreement" shall mean this agreement.

      14.   This agreement shall automatically terminate and be of no further 
force or effect (a) if at any time the Buyer Entities own less than 40,000 
shares of Preferred Stock or 46,000 shares of Common Stock, or (b) on the 
later of (i) the first date on which no shares of Preferred Stock are 
outstanding, and (ii) December 31, 2001.  

      15.   Except as required by the transactions contemplated herein, none 
of the rights, responsibilities or obligations of any of the parties hereto 
may be assigned.  Subject to the preceding sentence, this Agreement shall be 
binding on and inure to the benefit of the parties hereto, their successors 
and assigns.

                                        
                                        Very truly yours,
