                            MEETINGS OF STOCKHOLDERS
                            ------------------------

     Section 1. All  meetings of the  stockholders  shall be held in the City of
San Francisco,  State of California,  at such place as may be fixed from time to
time by the board of  directors,  or at such other place as shall be  designated
from  time to time by the board of  directors  and  stated in the  notice of the
meeting.

     Section 2. An annual meeting of stockholders shall be held during the month
of May in each  year,  on the date and at the time  during  such month as may be
determined from time to time by resolution adopted by the board of directors, at
which the stockholders shall elect by a plurality vote a board of directors, and
transact  such other  business as may properly be brought  before the meeting in
accordance with these bylaws.  To be properly brought before the annual meeting,
business  must be either (i)  specified in the notice of annual  meeting (or any
supplement  or amendment  thereto)  given by or at the direction of the board of
directors,  (ii)  otherwise  brought  before  the  annual  meeting  by or at the
direction  of the board of  directors,  or (iii)  otherwise  brought  before the
annual  meeting  by  a  stockholder.   In  addition  to  any  other   applicable
requirements,  for business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the secretary of the Corporation.  To be timely, a stockholder's  notice must be
delivered to or mailed and received at the  principal  executive  offices of the
Corporation,  not less than fifty (50) days nor more than seventy-five (75) days
prior to the  meeting;  provided,  however,  that in the  event  that  less than
sixty-five  (65)  days'  notice or prior  public  disclosure  of the date of the
annual meeting is given or made to  stockholders,  notice by a stockholder to be
timely must be so received not

                                       1

later than the close of business on the  fifteenth  (15th) day following the day
on which such notice of the date of the annual meeting was mailed or such public
disclosure  was made,  whichever  first occurs.  A  stockholder's  notice to the
secretary  shall set forth (a) as to each  matter the  stockholder  proposes  to
bring before the annual meeting (i) a brief  description of the business desired
to be brought  before the annual  meeting and the reasons  for  conducting  such
business  at the  annual  meeting,  (ii)  the  name and  record  address  of the
stockholder  proposing  such  business,  (iii) the  class,  series and number of
shares of capital stock of the Corporation  which are beneficially  owned by the
stockholder, and (iv) any material interest of the stockholder in such business,
and (b) as to the stockholder  giving the notice (i) the name and record address
of the  stockholder  and (ii) the class,  series and number of shares of capital
stock of the  Corporation  which  are  beneficially  owned  by the  stockholder.
Notwithstanding  anything in these bylaws to the contrary,  no business shall be
conducted at the annual  meeting  except in accordance  with the  procedures set
forth in this Article II, Section 2. The officer of the Corporation presiding at
an annual meeting shall,  if the facts warrant,  determine that business was not
properly  brought before the annual meeting in accordance with the provisions of
this Article II,  Section 2, and if he should so determine,  he shall so declare
to the annual  meeting and any such  business  not properly  brought  before the
meeting shall not be transacted.

     Section 3. A majority of the stock issued and  outstanding  and entitled to
vote at any meeting of stockholders,  the holders of which are present in person
or  represented  by proxy,  shall  constitute  a quorum for the  transaction  of
business except as otherwise provided by law, by the Corporation's charter or by
these bylaws. A quorum, once established,  shall not be broken by the withdrawal
of enough  votes to leave less than a quorum and the votes  present may continue
to transact business until  adjournment.  If, however,  such quorum shall not be
present or  represented  at any meeting of the  stockholders,  a majority of the
voting stock represented in person or by proxy may adjourn the meeting from time
to time  until a date not more than 120 days  after the  original  record  date,
without notice other than  announcement at the meeting,  until a quorum shall be
present or  represented.  At such  adjourned  meeting at which a quorum shall be
present or  represented,  any business may be  transacted  which might have been
transacted at the meeting as originally notified. If the adjournment is for more
than 120 days,  or if after the  adjournment  a new record date is fixed for the
adjourned  meeting,  a notice of the  adjourned  meeting  shall be given to each
stockholder of record entitled to vote thereat.

     Section 4. When a quorum is present at any meeting, the vote of the holders
of a majority of the stock having voting power present in person or  represented
by proxy shall  decide any  question  brought  before such  meeting,  unless the
question  is one  upon  which  by  express  provision  of the  Maryland  General
Corporation  Law ("MGCL") or the rules of any  securities  exchange on which the
Corporation's  capital  stock is listed or the  Corporation's  charter  or these
bylaws a different vote is required,  in which case such express provision shall
govern and control the decision of such question.

     Section 5. At each meeting of the stockholders, each stockholder having the
right to vote may vote in person or may authorize  another  person or persons to
act for him by proxy in any manner permitted by applicable law. All proxies must
be filed with the secretary of the  Corporation at the beginning of each meeting
in order to be counted in any vote at the meeting.  Subject to the provisions of
the charter of the Corporation,  each  stockholder  shall have one vote

                                       2


for each share of stock having voting power  registered in his name on the books
of the  Corporation on the record date set by the board of directors as provided
in Article V, Section 6 hereof. All elections shall be by a plurality vote.

     Section  6.  Special  meetings  of the  stockholders,  for any  purpose  or
purposes,  unless otherwise proscribed by the charter, may be called at any time
by the president,  the chairman of the board, or by a majority of the directors,
or by a committee of the board of directors  which has been duly  designated  by
the  board of  directors  and whose  powers  and  authority,  as  provided  in a
resolution of the board of directors or these bylaws,  include the power to call
such  meetings.  In  addition,  a special  meeting  of the  stockholders  of the
Corporation  shall be called by the secretary of the  Corporation on the written
request of  stockholders  entitled to cast at least fifty  percent  (50%) of all
votes entitled to be cast at the meeting,  except that, in the case of a special
meeting  called to  consider  any matter  which is  substantially  the same as a
matter  voted on at any  special  meeting for the  stockholders  held during the
preceding  twelve (12) months,  the  secretary of the  Corporation  shall not be
required to call any such  special  meeting  unless  requested  by  stockholders
entitled  to cast a  majority  of all of the  votes  entitled  to be cast at the
meeting.

     Section 7. Business transacted at any special meeting of stockholders shall
be limited to the purposes stated in the notice.  Where the Corporation's notice
of meeting  specifies that directors are to be elected at such special  meeting,
nominations  of persons for election to the board of  directors  may be made (i)
pursuant to the Corporation's notice of meeting,  (ii) by or at the direction of
the board of  directors or (iii) by any  committee  of persons  appointed by the
board of directors  with  authority  therefor or by a stockholder as provided in
Section 2 of Article III hereof.

     Section 8.  Whenever  stockholders  are  required or  permitted to take any
action at a meeting, a written notice of the meeting shall be given which notice
shall  state the  place,  date and hour of the  meeting,  and,  in the case of a
special  meeting,  the purpose or purposes for which the meeting is called.  The
written  notice of any meeting  shall be given to each  stockholder  entitled to
vote at such  meeting  not less than 10 nor more than 90 days before the date of
the meeting.  If mailed,  notice is given when  deposited  in the United  States
mail, postage prepaid,  directed to the stockholder at his address as it appears
on the records of the Corporation.

     Section  9.  Notwithstanding  any other  provision  of the  charter  of the
Corporation or these bylaws,  Subtitle 7 of Title 3 of the MGCL (as the same may
hereafter be amended from time to time) shall not apply to the voting  rights of
any shares of stock of the  Corporation now or hereafter held by any existing or
future  stockholder  of the  Corporation  (regardless  of the  identity  of such
stockholder).

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

     Section 1. The board of  directors  shall  consist of a minimum of five (5)
and a maximum of thirteen (13) directors. The number of directors shall be fixed
or  changed  from time to time,  within the  minimum  and  maximum,  by the then
elected  directors,  provided that at least a majority of the directors shall be
Independent Directors,  as defined from time to time by the Listing Standards of
the New York Stock Exchange and any other relevant laws,  rules and regulations.
Any  determination  by the board of  directors  as to the  qualification  of any
director as an  "Independent  Director"  shall be  conclusive  for all purposes.
Until  increased or decreased by the  directors  pursuant to these  bylaws,  the
exact  number  of  directors  shall  be ten  (10).  The  directors  need  not be
stockholders.  Except as provided in Section 2 of this  Article III with respect
to vacancies,  the directors shall be elected as provided in the charter at each
annual meeting of the stockholders,  and each director elected shall hold office
until his  successor is elected and  qualified  or until his death,  retirement,
resignation or removal.

     Section  2.  (a)  Nominations  of  persons  for  election  to the  board of
directors of the Corporation at the annual meeting of  stockholders  may be made
(i) pursuant to the Corporation's notice of meeting; (ii) by or at the direction
of the board of directors or (iii) by any committee of persons  appointed by the
board  of  directors  with  authority  therefor  or by  any  stockholder  of the
Corporation  entitled to vote for the  election of  directors at the meeting who
complies with the notice procedures set forth in this Article III, Section 2(a).
Such  nominations by any stockholder  shall be made pursuant to timely notice in
writing to the  Secretary  of the  Corporation.  To be timely,  a  stockholder's
notice shall be delivered to or mailed and received at the  principal  executive
offices of the  Corporation not less than 50 days nor more than 75 days prior to
the meeting; provided,  however, that in the event that less than 65 days notice
or  prior  public  disclosure  of the  date of the  meeting  is given or made to
stockholders,  notice by the  stockholder  to be timely must be so received  not
later than the close of business of the  fifteenth  (15th) day following the day
on which  such  notice of the date of the  meeting  was  mailed  or such  public
disclosure was made,  whichever first occurs.  Such stockholder's  notice to the
Secretary shall set forth (i) as to each person whom the stockholder proposes to
nominate for election or re-election as a director,  (a) the name, age, business
address and residence  address of the person,  (b) the  principal  occupation or
employment of the person, (c) the class,  series and number of shares of capital
stock of the Corporation which are beneficially owned by the person, and (d) any
other  information  relating to the person that is required to be  disclosed  in
solicitations  for proxies for election of  directors  pursuant to the Rules and
Regulations of the Securities  and Exchange  Commission  under Section 14 of the
Securities  Exchange  Act of 1934,  as amended;  and (ii) as to the  stockholder
giving the notice (a) the name and record address of the stockholder and (b) the
class, series and number of shares of capital stock of the Corporation which are
beneficially owned by the stockholder.  The Corporation may require any proposed
nominee to furnish such other  information  as may reasonably be required by the
Corporation to determine the eligibility of such proposed  nominee to serve as a
director of the Corporation. Except as may otherwise be provided in these bylaws
or any other agreement  relating to the right to designate nominees for election
to the board of  directors,  no  person  shall be  eligible  for  election  as a
director of the Corporation  unless  nominated in accordance with the procedures
set forth herein. The officer of

                                       4

the  Corporation  presiding at an annual  meeting  shall,  if the facts warrant,
determine  that a  nomination  was not made in  accordance  with  the  foregoing
procedure, and if he should so determine, he shall so declare to the meeting and
the defective nomination shall be disregarded.

         (b) Except as may  otherwise be provided  pursuant to Article IV of the
Corporation's  charter with respect to any rights of holders of preferred  stock
to elect additional directors and any other requirement in these bylaws or other
agreement  relating to the right to designate nominees for election to the board
of  directors,  should a vacancy in the board of  directors  occur or be created
(whether arising through death,  retirement or resignation),  such vacancy shall
be filled by the affirmative vote of a majority of the remaining directors, even
though less than a quorum of the board of directors or, in the case of a vacancy
resulting  from an  increase  in the number of  directors,  by a majority of the
entire board of directors.  In the case of a vacancy created by the removal of a
director,  the vacancy shall be filled by the  stockholders  of the  Corporation
entitled to elect the  director  who was  removed at the next annual  meeting of
stockholders or at a special  meeting of  stockholders  called for such purpose,
provided,  however, that such vacancy may be filled by the affirmative vote of a
majority of the  remaining  directors,  subject to approval by the  stockholders
entitled to elect the  director  who was  removed at the next annual  meeting of
stockholders or at a special meeting of stockholders  called for such purpose. A
director so elected to fill a vacancy shall serve for the remainder of the term.

     Section 3. The property and business of the Corporation shall be managed by
or under the direction of its board of directors.  In addition to the powers and
authorities by these bylaws expressly  conferred upon it, the board may exercise
all such powers of the Corporation and do all such lawful acts and things as are
not by statute or by the  Corporation's  charter or by these bylaws  directed or
required to be exercised or done by the stockholders.

notice on the written request of two directors unless the board consists of only
one director, in which case special meetings shall be called by the President or
Secretary  in like manner and on like notice on the written  request of the sole
director.

these bylaws, any action required or permitted to be taken at any meeting of the
board of directors or of any  committee  thereof may be taken without a meeting,

equipment  by means of which all persons  participating  in the meeting can hear
each other, and such  participation  in a meeting shall  constitute  presence in
person at such meeting.

     Section 9. By virtue of resolutions adopted by the Board of Directors prior
to or at the time of adoption of these Bylaws and  designated  irrevocable,  any
business  combination  (as defined in Section  3-601(e) of the MGCL) between the
Corporation and any of its present or future stockholders,  or any affiliates or
associates  of the  Corporation  or any  present  or future  stockholder  of the

exempt  from the  provisions  of  Subtitle  6 of  Title 3 of the  MGCL  entitled
"Special Voting Requirements,"  including, but not limited to, the provisions of

amend such  resolution,  or otherwise elect to have any business  combination of
the  Corporation  be subject to the  provisions  of Subtitle 6 of Title 3 of the
MGCL without the approval of the holders of the issued and outstanding shares of
Common Stock of the  Corporation  by the  affirmative  vote of a majority of all
votes entitled to be cast in respect of such shares of Common Stock.

     Section  10.  Notwithstanding  any other  provision  of these  bylaws,  all
actions which the board of directors  may take to approve a transaction  between
(i) the Corporation,  AMB Property,  L.P., a Delaware  limited  partnership (the
"Operating Partnership"),  or any subsidiary of the Corporation or the Operating

executive  officer or director  acting in the executive  officer's or director's
position  as such,  including  but not  limited  to  employment  agreements  and
compensation matters.

     Section 12. The board of directors may, by resolution  passed by a majority

with that  general  authorization  or any stock  option or other plan or program
adopted by the board of  directors:  authorize or fix the terms of stock subject
to classification or reclassification, including the designations and any of the

following  committees,  the specific  authority and members of which shall be as
designated herein, in such committee's charter or otherwise by resolution of the
board of directors:

          (i) An Executive Committee, which shall have such authority as granted

     interests of the Operating  Partnership,  to the extent that such interests
     are  exchangeable  into shares of the  Corporation's  capital stock, may be
     issued only if the  Corporation  has reserved  for issuance  such shares of
     capital  stock  issuable  upon the  exchange of such units or other  equity
     interests.

                                       7

     Independent  Directors  and  which  shall  determine  compensation  for the
     Corporation's  executive officers, and will review and make recommendations
     concerning  proposals by management  with respect to  compensation,  bonus,
     employment  agreements  and other  benefits  and policies  respecting  such
     matters for the executive officers of the Corporation.

     things, submit nominations for members of the Board of Directors, recommend
     composition  of the  committees of the Board of Directors,  review the size
     and composition of the Board of Directors,  review guidelines for corporate
     governance,  and conduct  annual  reviews of the Board of Directors and the
     Chief Executive Officer.

     Section 14. Each committee  shall keep regular  minutes of its meetings and
report the same to the board of  directors  when  required.  The  presence  of a
majority of the total  membership of any committee shall constitute a quorum for
the  transaction  of business at any meeting of such  committee and the act of a
majority of those present shall be necessary  and  sufficient  for the taking of
any action thereat.

directors or a stated salary as director.  Officers of the  Corporation  who are
also members of the board of directors shall not be paid any director's fees.

pending or completed  action,  suit or  proceeding,  whether or not by or in the
right  of  the  Corporation,   and  whether  civil,  criminal,   administrative,
investigative,  or otherwise, by reason of the fact that such person is or was a
director or officer of the  Corporation  or that such person while a director or
officer of the Corporation,  is or was serving at the request of the Corporation
as a director,  officer,  trustee, partner, member, agent or employee of another
corporation, partnership, limited liability company, association, joint venture,

fees),  judgments,  fines and amounts

                                       8


paid in  settlement,  and any such  expenses may be paid by the  Corporation  in
advance of the final disposition of such action, suit or proceeding.

     Neither the  amendment  nor repeal of this  Section 14 of this Article III,

the Corporation  inconsistent with this Section, shall apply to or affect in any
respect the applicability of the preceding  paragraph with respect to any act or
failure to act which occurred prior to such amendment, repeal or adoption.

     The indemnification and reimbursement of expenses provided herein shall not
be deemed to limit the right of the  Corporation  to indemnify  any other person
against any liability and expenses to the fullest  extent  permitted by law, nor
shall it be deemed  exclusive  of any other  rights to which any person  seeking
indemnification  from the Corporation  may be entitled under any agreement,  the
charter or bylaws of the  Corporation,  a vote of  stockholders  or  Independent
Directors, or otherwise, both as to action in such person's official capacity as
an officer or director and as to action in another  capacity,  at the request of
the Corporation, while acting as an officer or director of the Corporation.
