                                    FORM OF

October 30 of the preceding year, the Company shall have given notice that it
does not wish to extend this Agreement; provided, further, that if a Change in
Control (as defined in Section 2) occurs during the original or extended term of
this Agreement, this Agreement shall continue in effect until the later of
November 26, 2002 and twenty-four (24) months after the date on which such
Change in Control occurred (the "Change in Control Date").


         2. DEFINITIONS

         of the Executive's duties;

                  (b) the Executive's willful and continued failure to
         substantially perform the Executive's duties with the Company (other
         than a failure resulting from the Executive's incapacity due to
         physical or mental illness or any failure after the Executive's
         issuance of a Notice of Termination (as defined in Section 3.5)), after
         a written demand for substantial performance is delivered to the
         Executive by the Board of Directors (the "Board") of AMB Property
         Corporation, a Maryland corporation (the "General Partner");

                  (c) fraud or other conduct against the material best interests
         of the Company; or

                  (d) a conviction of a felony if such conviction has a material
         adverse effect on the Company.

         A "Change in Control" shall be deemed to occur if:



                                       1
   2

                  (a) the shareholders of the General Partner approve a plan of
         complete liquidation of the General Partner or an agreement for the
         sale or disposition by the General Partner of all or substantially all

         combined voting power of the General Partner's then outstanding
         securities. For purposes of this Agreement, (A) the term "Person" is
         used as such term is used in Sections 13(d) and 14(d) of the Securities
         Exchange Act of 1934, as amended (the "Exchange Act"); provided,
         however, that the term shall not include the General Partner, any
         trustee or other fiduciary holding securities under an employee benefit
         plan of the General Partner, and any corporation owned, directly or
         indirectly, by the shareholders of the General Partner, in
         substantially the same proportions as their ownership of stock of the
         General Partner, and (B) the term "Beneficial Owner" shall have the
         meaning given to such term in Rule 13d-3 under the Exchange Act;

                  (c) during any period of two (2) consecutive years (not
         including any period prior to the execution of this Agreement),

         has entered into an agreement with the General Partner to effect a
         transaction described in clauses (a), (b) or (d)) whose election by the
         Board or nomination for election by the General Partner's shareholders
         was approved by a vote of at least two-thirds (2/3) of the directors
         then still in office who either were directors at the beginning of the
         period or whose election or nomination for election was previously so
         approved, cease for any reason to constitute at least a majority
         thereof; or

                  (d) the shareholders of the General Partner approve a merger
         or consolidation of the General Partner with any other corporation (or
         other entity), other than (i) a merger or consolidation which would
         result in the voting securities of the General Partner outstanding
         immediately prior thereto continuing to represent (either by remaining
         outstanding or by being converted into voting securities of the
         surviving entity) more than fifty percent (50%) of the combined voting
         power of the voting securities of the General Partner or such surviving
         entity outstanding immediately after such merger or consolidation or
         (ii) where more than fifty percent (50%) of the directors of the
         General Partner or the surviving entity after such merger or
         consolidation were directors of the General Partner immediately before
         such merger or consolidation.

                  (a) if the Executive's employment is terminated by his death,
         the date



                                       2
   3

         of his death;

                  (b) if the Executive's employment is terminated by reason of
         his Disability, the date of the opinion of the physician referred to in
         the definition of "Disability" hereof; or

                  (c) if the Executive's employment is terminated by the Company
         or by the Executive for any reason other than death or Disability, the
         date specified in the Notice of Termination;

provided, that, if within fifteen (15) days after any Notice of Termination (as
defined in Section 3.5) is given, the party receiving such Notice of Termination
notifies the other party that a dispute exists concerning the termination, then
the Date of Termination shall be the date on which the dispute is finally
resolved, either by mutual written agreement of the parties, or otherwise;
provided, however, that the Date of Termination shall be extended by a notice of
dispute only if such notice is given in good faith and the party giving such
notice pursues the resolution of such dispute with reasonable diligence.

         "Disability" shall mean the Executive's physical or mental disability
or infirmity which, in the opinion of a competent physician selected by the
Board, renders the Executive unable to perform properly his duties as an
employee of the Company, and as a result, the Executive is unable to perform
such duties for six (6) consecutive calendar months or for shorter periods
aggregating one hundred and eighty (180) business days in any twelve (12) month
period, but only to the extent that such definition does not violate the
Americans with Disabilities Act.

         "Good Reason" shall mean, without the Executive's express written
consent, the occurrence after a Change in Control of any of the following
circumstances unless such circumstances are fully corrected (provided such
circumstances are capable of correction) prior to the Date of Termination as
specified in the Notice of Termination:

                  (a) the assignment to the Executive of any duties inconsistent
         with the position in the Company that the Executive held immediately
         prior to the Change in Control Date, a significant adverse alteration
         in the nature or status of the Executive's responsibilities or the
         conditions of the Executive's employment from those in effect
         immediately prior to the Change in Control Date, or any other action by
         the Company that results in a material diminution in the Executive's
         position, authority, duties or responsibilities from those in effect
         immediately prior to the Change in Control Date;

                  (b) a reduction in the Executive's annual base compensation as
         in effect on the Change in Control Date;

                  (c) the relocation of the Company's offices at which the
         Executive is principally employed immediately prior to the Change in
         Control Date (the "Principal Location") to a location more than fifty
         (50) miles from such location or the Company's



                                       3
   4

         requiring the Executive, without the Executive's written consent, to be
         based anywhere other than the Principal Location, except for required
         travel on the Company's business to an extent substantially consistent
         with the Executive's business travel obligations prior to the Change in
         Control Date;

                  (d) the Company's failure to pay to the Executive any portion
         of the Executive's compensation or to pay to the Executive any portion
         of an installment of deferred compensation under any deferred
         compensation program of the Company within seven (7) days of the date
         such compensation is due; or

                  (e) the Company's failure to continue in effect any material
         compensation or benefit plan or practice in which the Executive is
         eligible to participate in on the Change in Control Date (other than
         any equity based plan), unless an equitable arrangement (embodied in an
         ongoing substitute or alternative plan) has been made with respect to
         such plan, or the Company's failure to continue the Executive's
         participation therein (or in such substitute or alternative plan) on a
         basis not materially less favorable, both in terms of the amount of
         benefits provided and the level of the Executive's participation
         relative to other participants, as existed at the time of the Change in
         Control Date;

provided, however, that the Executive's continued employment shall not
constitute consent to, or a waiver of rights with respect to, any circumstance
constituting Good Reason hereunder.


         3. COMPENSATION UPON TERMINATION

                  3.1. Death.

                       Whether or not there is a Change in Control, if the
Executive's employment shall be terminated due to the Executive's death, the
Company shall pay monthly to the Executive's estate for a period equal to one
(1) year following the Date of Termination an amount equal to the sum of: (i)
one-twelfth of the Executive's annual base compensation as in effect on the Date
of Termination plus (ii) one-twelfth of any bonus at the most recent annual
amount received, or entitled to be received, by the Executive for the most
recent annual period. At the Executive's estate's expense, the Executive's
spouse and children shall also be entitled to any continuation of health
insurance coverage rights under any applicable law.

                  3.2. Disability.

                       Whether or not there is a Change in  Control,  if the 
Executive's employment shall be terminated by reason of Disability, the Company
shall pay to the Executive a single payment in an amount equal to the sum of:
(i) the Executive's annual base compensation as in effect on the Date of
Termination plus (ii) an amount equal to the annual bonus received, or entitled
to be received, by the Executive for the most recent annual period. Such payment
shall be in addition to any disability insurance payments to which the Executive
is otherwise entitled. At the Executive's own expense, the Executive and the
Executive's spouse and children shall also be entitled to any continuation of
health insurance coverage rights under any applicable law.



                                       4
   5

                  3.3. Termination Upon Change in Control.

                       If  during  the  term or  extended  term of this
Agreement and within two (2) years following a Change in Control, the
Executive's employment with the Company is terminated, in addition to his base
compensation and any bonus then payable through the Date of Termination and, at
the Executive's own expense, any continuation of health insurance coverage
rights under any applicable law, the Executive shall be entitled to the benefits
provided below, unless such termination is (i) because of the Executive's death,
Disability or retirement, (ii) by the Company for Cause or (iii) by the
Executive other than for Good Reason; provided, however, that in the event the
Executive's employment is terminated for any reason and subsequently a Change in
Control occurs, the Executive shall not be entitled to any benefits hereunder,
other than pursuant to Sections 3.1 and 3.2:

                           (a) the Company shall pay to the Executive, when due,
the Executive's base compensation and any bonus then payable through the Date of
Termination;

                           (b) in lieu of any further salary payments to the
Executive for periods subsequent to the Date of Termination, the Company shall
pay as severance pay to the Executive during the Nonsolicitation Period (as
defined in Section 4.3) a monthly payment equal to 1/24 of the sum of the
following:

                                    (i)  two (2) times the Executive's annual
base compensation as in effect as of the Date of Termination or immediately
prior to the Change in Control Date, whichever is greater; and

                                    (ii) two (2) times the annual bonus
received, or entitled to be received, by the Executive for the most recent
annual period;

                           (c) for a twelve (12) month period after such
termination (the "Coverage Period"), the Company shall continue to provide the
Executive and the Executive's eligible family members with medical and dental
health benefits and life and disability insurance at least equal to those which
would have been provided to the Executive and them if the Executive's employment
had not been terminated or, if more favorable to the Executive, as in effect
generally at any time thereafter; provided, however, that if the Executive
becomes re-employed with another employer and is eligible to receive medical and
dental health benefits and life and disability insurance under another
employer's plans, the Company's obligations under this Section 3.3(c) shall be
reduced to the extent comparable benefits are actually received by the Executive
during the twelve (12) month period following the Executive's termination, and
any such benefits actually received by the Executive shall be reported to the
Company; and 

                           (d) the Company shall pay to the Executive on or
about the date or dates that the contributions would have been made an amount
equal to the aggregate amount of the Company's maximum contributions that would
have been made under the Company's 401(k) plan (the "401(k) Plan") during the
Coverage Period if the Executive had continued to be employed and participated
in the 401(k) Plan during the Coverage Period.

   6

                  3.4. Limitation. The foregoing notwithstanding, the total of
the payments made to the Executive pursuant to Sections 3.1, 3.2 or 3.3 hereof
shall be reduced to the extent that the payment of such amount would cause the
Executive's total termination benefits (as determined by the Executive's tax
advisor) to constitute an "excess" parachute payment under Section 280G of the
Code, and by reason of such excess parachute payment the Executive would be
subject to an excise tax under Section 4999(a) of the Code, but only if the
Executive determines that the after-tax value of the termination benefits
calculated with the foregoing restriction exceed those calculated without the
foregoing restriction.

                  3.5 Notice. Any termination of the Executive's employment by
the Company or the Executive shall be communicated by written notice of
termination to the other party (the "Notice of Termination"). The Notice of
Termination shall indicate the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated.

                  3.6 Termination Obligations.

                           (a) The Executive hereby acknowledges and agrees that
all Personal Property and equipment furnished to or prepared by the Executive in
the course of or incident to his employment, belongs to the Company and shall be
promptly returned to the Company upon termination of the Executive's employment.
"Personal Property" includes, without limitation, all electronic devices of the
Company used by the Executive, including, without limitation, personal
computers, facsimile machines, cellular telephones, pagers and tape recorders
and all books, manuals, records, reports, notes, contracts, lists, blueprints,
maps and other documents, or materials, or copies thereof (including computer
files), and all other proprietary information relating to the business of the
Company. Following termination, the Executive will not retain any written or
other tangible material containing any proprietary information of the Company.

                           (b) The Executive's obligations under this Section
23.6 and Section 4 hereof shall survive termination of the Executive's
employment and the expiration of this Agreement.

                           (c) Upon termination of the Executive's employment,
the Executive will be deemed to have resigned from all offices and directorships
then held with the Company or any affiliate.

                  3.7. No Duty to Mitigate. The Executive shall not be required
to mitigate the amount of any payment provided for herein by seeking other
employment or otherwise, nor shall the amount of any payment or benefit provided
for herein be reduced by any compensation earned by the Executive as the result
of employment by another employer.

         4. CONFIDENTIALITY, NONCOMPETITION AND NONSOLICITATION COVENANTS




                                       6
   7

                  4.1. Confidentiality. In consideration of and in connection
with the benefits provided to the Executive under this Agreement, the Executive
hereby agrees that the Executive will not, during the Executive's employment or
at any time thereafter directly or indirectly disclose or make available to any
person, firm, corporation, association or other entity for any reason or purpose
whatsoever, any Confidential Information (as defined below). The Executive
agrees that, upon termination of his employment with the Company, all
Confidential Information in his possession that is in written or other tangible
form (together with all copies or duplicates thereof, including computer files)
shall be returned to the Company and shall not be retained by the Executive or
furnished to any third party, in any form except as provided herein; provided,
however, that the Executive shall not be obligated to treat as confidential, or
return to the Company copies of any Confidential Information that (i) was
publicly known at the time of disclosure to the Executive, (ii) becomes publicly
known or available thereafter other than by any means in violation of this
Agreement or any other duty owed to the Company by the Executive, or (iii) is
lawfully disclosed to the Executive by a third party. As used in this Agreement
the term "Confidential Information" means information disclosed to the Executive
or known by the Executive as a consequence of or through his relationship with
the Company, about the owners, tenants, employees, consultants, vendors,
business methods, public relations methods, organization, procedures, property
acquisition and development, or finances, including, without limitation,
information of or relating to owner or tenant lists of the Company and its
affiliates.

                  4.2. Noncompetition. During the term of the Executive's
employment, the Executive shall not engage in any activities, directly or
indirectly, in respect of commercial real estate, and will not make any
investment in respect of industrial or retail real estate, other than through
ownership of not more than five percent (5%) of the outstanding shares of a
public company engaged in such activities and through investments listed on
Schedule I to the Employment Agreement (as defined below).

                  4.3. Nonsolicitation. In consideration of and in connection
with the benefits provided to the Executive under this Agreement, for a period
of two (2) years following the Date of Termination (the "Nonsolicitation
Period"), the Executive shall not solicit or induce any of the Company's or its
affiliates' employees, agents or independent contractors to end their
relationship with the Company or its affiliates, or recruit, hire or otherwise
induce any such person to perform services for the Executive, or any other
person, firm or company.

         5. GENERAL PROVISIONS

                  5.1. Termination of Employment Agreement. The parties hereby
agree that the Employment Agreement dated as of November 26, 1997 (the
"Employment Agreement") between the Executive and the Company is hereby
terminated as of the date hereof, the Employment Agreement shall be of no
further force and effect as of the date hereof and the parties shall be released
from any further obligations thereunder.

                  5.2. Successors; Binding Agreement

                           (a) The Company shall require any successor (whether
direct or



                                       7
   8

indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to receive compensation from the
Company in the same amount and on the same terms to which the Executive would be
entitled hereunder if the Executive terminated the Executive's employment for
Good Reason following a Change in Control, except that for purposes of
implementing the foregoing, the date on which any such succession becomes
effective shall be deemed the Date of Termination. Unless expressly provided
otherwise, "Company" as used herein shall mean the Company as defined in this
Agreement and any successor to its business and/or assets as aforesaid.

                           (b) This Agreement shall inure to the benefit of and
be enforceable by the Executive and the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If the Executive should die while any amount would still
be payable to the Executive hereunder had the Executive continued to live, all
such amounts, unless otherwise provided herein, shall be paid in accordance with
the terms of this Agreement to the Executive's devisee, legatee or other
designee or, if there is no such designee, to the Executive's estate.

                  5.3. Injunctive Relief and Enforcement. The Executive
acknowledges that the remedies at law for any breach by him of the provisions of
Sections 3.6 or 4 hereof may be inadequate and that, therefore, in the event of
breach by the Executive of the terms of Sections 3.6 or 4 hereof, the Company
shall be entitled to institute legal proceedings to enforce the specific
performance of this Agreement by the Executive and to enjoin the Executive from
any further violation of Sections 3.6 or 4 hereof and to exercise such remedies
cumulatively or in conjunction with all other rights and remedies provided by
law and not otherwise limited by this Agreement.

                  5.4. No Contract of Employment. The Executive acknowledges
that the Executive's employment with the Company is at will. This Agreement
shall not confer upon the Executive any right of continued or future employment
by the Company or any right to compensation or benefits from the Company except
the rights specifically stated herein, and shall not limit the right of the
Company to terminate the Executive's employment at any time with or without
cause.

                  5.5. Notice. For the purposes of this Agreement, notices,
demands and all other communications provided for in this Agreement shall be in
writing and shall be deemed to have been duly given when addressed as follows
and (i) when personally delivered, (ii) when transmitted by telecopy, electronic
or digital transmission with receipt confirmed, (iii) one day after delivery to
an overnight air courier guaranteeing next day delivery, or (iv) upon receipt if
sent by certified or registered mail. In each case notice shall be sent to:

provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision of this Agreement, which shall remain in
full force and effect. In addition, in the event any provision in this Agreement
shall be determined by any court of competent jurisdiction to be unenforceable
by reason of extending for too great a period of time or over too great a
