Item 5.  Other Events

         Subsequent to September 30, 1998, AMB Property Corporation (the
         "Company") has invested approximately $162 million in 40 industrial
         buildings aggregating 3.5 million rentable square feet and
         approximately $17 million in one retail center comprised of 0.1 million
         rentable square feet.

         The operating properties covered by the attached financial statements
         were acquired by AMB Property, L.P. and subsidiaries (the "Operating
         Partnership") from unrelated parties between July 31, 1998, and October
         26, 1998. The Company owns a controlling approximate 95.1% general
         partnership interest in the Operating Partnership as of September 30,
         1998. The Company is the sole general partner of the Operating
         Partnership and has the full, exclusive and complete responsibility and
         discretion in the management and control of the Operating Partnership.
         Therefore, the Company consolidates the Operating Partnership for
         financial reporting purposes. None of the acquisitions were

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To AMB Property Corporation:

    We have audited the accompanying combined statement of revenues and certain
expenses of the Amberjack Portfolio (as defined in Note 1) for the year ended
December 31, 1997. This financial statement is the responsibility of the
management of the Amberjack Portfolio. Our responsibility is to express an
opinion on this financial statement based on our audit.

    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined statement of revenues and
certain expenses is free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the combined
statement of revenues and certain expenses. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

    The accompanying combined statement of revenues and certain expenses was
prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission's rules and regulations, as described in Note 1, and is not
intended to be a complete presentation of the revenues and expenses of the
Amberjack Portfolio.

    In our opinion, the combined statement of revenues and certain expenses
referred to above presents fairly, in all material respects, the revenues and
certain expenses of the Amberjack Portfolio for the year ended December 31,
1997, in conformity with generally accepted accounting principles.

                              AND CERTAIN EXPENSES
                             (DOLLARS IN THOUSANDS)

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Properties Acquired

    The accompanying combined statements of revenues and certain expenses
include the combined operations (see "Basis of Presentation" below) of the
Amberjack Portfolio (the "Portfolio"). AMB Property Corporation and 
Subsidiaries (the "Company") acquired the Portfolio, which includes 44
industrial buildings aggregating approximately 2.1 million square feet
(unaudited), from an unrelated party on July 31, 1998 for an initial purchase
price of approximately $78,500 (unaudited).

Basis of Presentation

    The accompanying combined statements of revenues and certain expenses are
not representative of the actual operations of the Portfolio for the periods
presented. Certain expenses may not be comparable to the expenses expected to be
incurred by the Company in the proposed future operations of the Portfolio;
however, the Company is not aware of any material factors relating to the
Portfolio that would cause the reported financial information not to be
indicative of future operating results. Excluded expenses consist of interest,
depreciation and amortization and other costs not directly related to the future
operations of the Portfolio.

    The combined statements of revenues and certain expenses have been prepared
for the purpose of complying with Rule 3-14 of the Securities and Exchange
Commission's rules and regulations.

    The financial information presented for the period from January 1, 1998 to
July 31, 1998 is unaudited. In the opinion of management, the unaudited
financial information contains all adjustments, consisting of normal recurring
accruals, necessary for a fair presentation of the combined statement of
revenues and certain expenses for the Portfolio.

Revenue Recognition

    All leases are classified as operating leases, and rental revenue is
recognized on a straight-line basis over the terms of the leases.

Uses of Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
periods presented. Actual results could differ from those estimates.

2. LEASING ACTIVITY

    Future minimum rental income due under non-cancelable operating leases with
tenants in effect as of December 31, 1997 is as follows:

2. LEASING ACTIVITY (CON'T)


    In addition to minimum rental payments, tenants pay reimbursements for their
pro rata share of specified operating expenses, which amounted to $1,287 and
$776 for the year ended December 31, 1997 and for the period from January 1,
1998 to July 31, 1998 (unaudited), respectively. Certain leases contain options
to renew.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To AMB Property Corporation:

    We have audited the accompanying combined statement of revenues and certain
expenses of the Willow Park Portfolio (as defined in Note 1) for the year ended
December 31, 1997. This financial statement is the responsibility of
the management of the Willow Park Portfolio. Our responsibility is to express an
opinion on this financial statement based on our audit.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined statement of revenues and
certain expenses is free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the combined
statement of revenues and certain expenses. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

    The accompanying combined statement of revenues and certain expenses was
prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission's rules and regulations, as described in Note 1, and is not
intended to be a complete presentation of the revenues and expenses of the
Willow Park Portfolio.

     In our opinion, the combined statement of revenues and certain expenses
referred to above presents fairly, in all material respects, the revenues and
certain expenses of the Willow Park Portfolio for the year ended December 31,
1997, in conformity with generally accepted accounting principles.

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Properties Acquired

     The accompanying combined statements of revenues and certain expenses
include the operations of the Willow Park Portfolio (the "Portfolio") acquired
by AMB Property Corporation and Subsidiaries (the "Company") from an unrelated
party on September 24, 1998 for an initial purchase price of approximately
$100,400 (unaudited), including the assumption of mortgages payable (see Note
3). The Portfolio is located in the San Francisco Bay Area and includes 21
industrial buildings comprising approximately 1.0 million rentable square feet
(unaudited).

Basis of Presentation

    The accompanying combined statements of revenues and certain expenses are
not representative of the actual operations of the Portfolio for the periods
presented. Certain expenses may not be comparable to the expenses expected to be
incurred by the Company in the proposed future operations of the Portfolio;
however, the Company is not aware of any material factors relating to the
Portfolio that would cause the reported financial information not to be
indicative of future operating results. Excluded expenses consist of interest,
depreciation and amortization and other costs not directly related to the future
operations of the Portfolio.

    The combined statements of revenues and certain expenses have been prepared
for the purpose of complying with Rule 3-14 of the Securities and Exchange
Commission's rules and regulations.

    The combined financial information presented for the period from January 1,
1998 to September 24, 1998 is unaudited. In the opinion of management, the
unaudited financial information contains all adjustments, consisting of normal
recurring accruals, necessary for a fair presentation of the combined statement
of revenues and certain expenses for the Portfolio.

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Properties Acquired

    The accompanying combined statements of revenues and certain expenses
include the operations (see "Basis of Presentation" below) of the National
Distribution Portfolio (the "Portfolio"). AMB Property Corporation (the
"Company") acquired the Portfolio, which includes 24 industrial buildings
aggregating 2.2 million square feet (unaudited), from an unrelated party on
October 26, 1998 for an initial purchase price of approximately $92,500
(unaudited), which includes the assumption of mortgages payable (see Note 3).

Basis of Presentation

    The accompanying statements of revenues and certain expenses are not
representative of the actual operations of the Portfolio for the periods
presented. Certain expenses may not be comparable to the expenses expected to be
incurred by the Company in the proposed future operations of the Portfolio;
however, the Company is not aware of any material factors relating to the
Portfolio that would cause the reported financial information not to be
indicative of future operating results. Excluded expenses consist of interest,
depreciation and amortization and other costs not directly related to the future
operations of the Portfolio.

    The combined statements of revenues and certain expenses have been prepared
for the purpose of complying with Rule 3-14 of the Securities and Exchange
Commission's rules and regulations.

    The financial information presented for the nine months ended September 30,
1998 is unaudited. In the opinion of management, the unaudited financial
information contains all adjustments, consisting of normal recurring accruals,
necessary for a fair presentation of the combined statement of revenues and
certain expenses for the Portfolio.

Revenue Recognition

    All leases are classified as operating leases, and rental revenue is
recognized on a straight-line basis over the terms of the leases.

Uses of Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
periods presented. Actual results could differ from those estimates.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To AMB Property Corporation:

     We have audited the accompanying combined statement of revenues and certain
expenses of the Mawah Portfolio (as defined in Note 1) for the year ended
December 31, 1997. This financial statement is the responsibility of the
management of the Mawah Portfolio. Our responsibility is to express an opinion
on this financial statement based on our audit.

    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined statement of revenues and
certain expenses is free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the combined
statement of revenues and certain expenses. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall combined financial statement presentation. We believe
that our audit provides a reasonable basis for our opinion.

    The accompanying combined statement of revenues and certain expenses was
prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission's rules and regulations, as described in Note 1, and is not
intended to be a complete presentation of the revenues and expenses of the Mawah
Portfolio.

    In our opinion, the combined statement of revenues and certain expenses
referred to above presents fairly, in all material respects, the revenues and
certain expenses of the Mawah Portfolio for the year ended December 31, 1997, in
conformity with generally accepted accounting principles.

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Properties Acquired

     The accompanying combined statements of revenues and certain expenses
include the combined operations (see "Basis of Presentation" below) of the Mawah
Portfolio (the "Property"). AMB Property Corporation and Subsidiaries (the
"Company") acquired the Property from an unrelated party on October 8, 1998 for
an initial purchase price of approximately $41,900 (unaudited). The Property is
located in Mawah, New Jersey, and includes seven industrial buildings
aggregating 579,029 rentable square feet (unaudited).

Basis of Presentation

    The accompanying combined statements of revenues and certain expenses are
not representative of the actual operations of the Property for the periods
presented. Certain expenses may not be comparable to the expenses expected to be
incurred by the Company in the proposed future operations of the Property;
however, the Company is not aware of any material factors relating to the
Property that would cause the reported financial information not to be
indicative of future operating results. Excluded expenses consist of interest,
depreciation and amortization and other costs not directly related to the future
operations of the Property.

    The combined statements of revenues and certain expenses have been prepared
for the purpose of complying with Rule 3-14 of the Securities and Exchange
Commission's rules and regulations.

    The financial information presented for the nine months ended September 30,
1998 is not audited. In the opinion of management, the unaudited financial
information contains all adjustments, consisting of normal recurring accruals,
necessary for a fair presentation of the combined statement of revenues and
certain expenses for the Property.

Revenue Recognition

    All leases are classified as operating leases, and rental revenue is
recognized on a straight-line basis over the terms of the leases.

Uses of Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
periods presented. Actual results could differ from those estimates.

2. LEASING ACTIVITY

    Future minimum rental income due under non-cancelable operating leases with
tenants in effect as of December 31, 1997 is as follows:

pro rata share of specified operating expenses, which amounted to $293 and $171
for the year ended December 31, 1997 and for the nine months ended September 30,
1998 (unaudited), respectively. Certain leases contain options to renew.

                   PRO FORMA FINANCIAL INFORMATION (UNAUDITED)

BACKGROUND

    The accompanying unaudited pro forma condensed consolidated balance sheet as
of September 30, 1998 has been prepared to reflect: (i) the acquisition of
properties subsequent to September 30, 1998, (ii) the sale of Series B Preferred
Units and the application of the net proceeds therefrom and (iii) the sale of
Series C Preferred Units and the application of the net proceeds therefrom as if
such transactions and adjustments had occurred on September 30, 1998. The
accompanying unaudited pro forma condensed consolidated statements of operations
for the year ended December 31, 1997 and the nine months ended September 30,
1998 have been prepared to reflect: (i) the incremental effect of the
acquisition of properties during 1998 and 1997, (ii) the incremental effect of
the disposition or partial disposition of properties during 1997, (iii) the IPO
and Formation Transactions, (iv) pro forma debt and other adjustments resulting
from the sale of Senior Debt Securities, the sale of Series A Preferred Shares,
the sale of Series B Preferred Units and the sale of Series C Preferred Units
and the application of the resulting net proceeds and (v) certain other
adjustments as if such transactions and adjustments had occurred on January 1,
1997 and were carried forward through September 30, 1998.

    These unaudited pro forma condensed consolidated statements should be read
in connection with the historical consolidated financial statements and notes
thereto included in AMB Property Corporation's December 31, 1997 Form 10-K and 
September 30, 1998 Form 10-Q. In the opinion of management, the pro forma
condensed consolidated financial information provides for all adjustments
necessary to reflect the effects of the IPO and Formation Transactions, the sale
of Senior Debt Securities, the sale of Series A Preferred Shares, the sale of
Series B Preferred Units and the sale of Series C Preferred Units and the
application of the resulting net proceeds therefrom, property acquisitions and
dispositions and certain other transactions.

    The pro forma information is unaudited and is not necessarily indicative of
the consolidated results that would have occurred if the transactions and
adjustments reflected therein had been consummated in the period or on the date
presented, or on any particular date in the future, nor does it purport to
represent the financial position, results of operations or changes in cash flows
for future periods.

    Five of the property acquisitions, Jamesburg Property, Corporate Park
Industrial, Garland Industrial Portfolio, Minnetonka Industrial Portfolio and
South Point Business Park, represent a joint venture with a client of AMB
Investment Management in which the Company owns a controlling 50.0005% interest.
The joint venture acquisitions are accounted for on a consolidated basis and,
accordingly, minority interest of $2,384 has been reflected relative to these
acquisitions.

    Two of the acquisitions above, Forbes and Southfield, represent the purchase
of vacant buildings which are in the process of being leased. As such, no
property operations have been reflected in the accompanying pro forma statement
of operations relative to these acquisitions.

    Also reflects the acquisition of a non-controlling unconsolidated limited
partnership interest in an existing real estate joint venture which owns the
DuPage Elk Grove Property. As such, the Company's incremental share of equity in
earnings of this joint venture of $2,988 is included in interest and other
income in the accompanying pro forma statement of operations.

    Also reflects the estimated incremental depreciation and amortization of the
1998 property acquisitions based on estimated useful lives of 40 years.

    3. Reflects an adjustment to derive pro forma interest expense, which is
based upon the pro forma debt balances as of September 30, 1998. The calculation
of pro forma interest expense is as follows:
<TABLE>
<CAPTION>

<S>                                                               <C>     
Secured debt, pro forma balance of $737,752 (before
  premium of  $15,918), assumed interest rate of 7.90% ....       $ 43,712

Credit Facility, pro forma balance of $154,808, assumed
  interest rate of 6.53% ..................................          7,582

Senior Debt Securities, pro forma balance of $400,000,
  weighted average interest rate of 7.175% ................         21,525

Amortization of debt premium, actual amounts amortized
  during the period .......................................         (2,664)

Amortization of deferred financing costs, $6,434 balance,
  3 to 17 year terms ......................................            743

Unused Credit Facility fees, unused pro forma balance of
  $345,192, fee of 0.15% ..................................            388

Capitalized interest, actual amounts capitalized during
  the period ..............................................         (4,974)
                                                                  --------

Pro forma interest expense ................................       $ 66,312
                                                                  ========
</TABLE>

    The net change in interest expense is the result of the repayment of
borrowings on the Credit Facility of approximately $394,466 with the net
proceeds from the sale of the Senior Debt Securities (see below) and
approximately $267,000 from the sale of Series A Preferred Shares, the sale of
Series B Preferred Units and sale of the Series C Preferred Units offset by
borrowings on the Credit Facility related to property acquisitions and the
assumption of secured debt in connection with property acquisitions.

    In June 1998, the Operating Partnership issued $400,000 aggregate principal
amount of unsecured notes ("Senior Debt Securities") in an underwritten public
offering, of which the net proceeds of approximately $394,466 were contributed
to the Operating Partnership and used to repay amounts outstanding under the
Credit Facility. The Senior Debt Securities mature in June 2008. June 2015 and
June 2018 and bear interest at a weighted average rate of 7.18%.

    Also reflects the payment of pro forma Series A Preferred Stock dividends at
a dividend rate of 8.5%, Series B Preferred Unit distributions at a distribution
rate of 8.625% and Series C Preferred Unit distributions at a distribution rate
of 8.75%.

    4. The pro forma taxable income of the Company for the twelve months ended
September 30, 1998 is approximately $108,919, which is based upon pro forma
income from operations of approximately $115,847, plus book depreciation and
amortization of approximately $58,401 less other book/tax differences of
approximately $7,409 and less tax depreciation and amortization of approximately
$57,920

</TABLE>

    One of the acquisitions above, Manhattan Village, represents the acquisition
of a property and the formation of several joint ventures that own the property,
in which the Company owns a 90% interest. The joint venture is accounted for on
a consolidated basis, and accordingly, a 10% minority interest has been
reflected relative to this acquisition.

    4. Reflects the incremental effects of the disposition or partial
disposition of properties during 1997, based upon the historical operations of
such properties.

    5. Reflects the effects of the application of purchase accounting as a
result of the IPO and Formation Transactions, resulting in pro forma expense
adjustments as follows: (i) an increase in depreciation expense of $9,232, (ii)
the reclassification of certain property-related expenses from general and
administrative expense to property operating expense (due to the internalization
of management) of approximately $5,196 and (iii) a net 

                                       32
<PAGE>   33


increase in general, administrative and other expenses of $5,958, after
reclassification of property-related expenses. Such changes are based upon
actual expenses incurred during 1997 adjusted for (a) the estimated changes in
costs due to operating as a public entity including investor relations,
accounting and legal fees and other costs related to the internalization of
management and (b) certain reclassifications to reflect the Company's new
organizational structure as a result of the IPO. Estimated depreciation and
amortization has been based upon asset lives of 5 to 40 years.

    Also reflects the elimination of advisory fees charged by the Company's
predecessor, AMB, to the owners of the AMB Contributed Properties of $15,521
(excluding approximately $2,027 in real estate acquisition fees paid to AMB
which have been accounted for as acquisition costs by the owners of the AMB
Contributed Properties and accordingly capitalized as investments in real
estate). Also reflects the elimination of investment management and advisory
fees earned by AMB of $28,756 and related expenses of $19,358 resulting from the
change in the Company's operations from an investment manager to a real estate
operating company.

    Also reflects an adjustment to historical interest expense to derive 1997 as
adjusted interest expense, which is based upon the Company's debt balances as of
December 31, 1997. The calculation of 1997 as adjusted interest expense is as
follows:

</TABLE>

    Five of the property acquisitions, Jamesburg Property, Corporate Park
Industrial, Garland Industrial Portfolio, Minnetonka Industrial Portfolio and
South Point Business Park, represent joint ventures with a client of AMB
Investment Management in which the Company owns a controlling 50.0005% interest.
The joint venture acquisitions are accounted for on a consolidated basis and,
accordingly, a minority interest of $5,996 has been reflected relative to these
acquisitions.

    Also reflects the acquisition of a non-controlling limited partnership
interest in an existing real estate joint venture which owns the DuPage Elk
Grove Property. As such, the Company's share of equity in earnings of this joint
venture of $5,086 is included in interest and other income in the accompanying
pro forma statement of operations.

    Also reflects estimated incremental depreciation and amortization of the
1998 property acquisitions based on estimated useful lives of 40 years.

    7. Reflects an adjustment to derive pro forma interest expense, which is
based upon the pro forma debt balances as of September 30, 1998. The calculation
of pro forma interest expense is as follows:
<TABLE>

Secured debt, pro forma balance of $737,752 (before
  premium of $15,918), assumed interest rate of 7.90% .............   $ 58,282

Credit Facility, pro forma balance of $154,808, assumed
  interest Rate of 6.53% ..........................................     10,109

Senior Debt Securities, pro forma balance of $400,000,
  weighted average interest rate of 7.175% ........................     28,700

Amortization of deferred financing costs, $6,434 balance,
  3 to 17  year terms .............................................        990

Amortization of debt premium, $15,918 balance, 8 year term ........     (2,976)
Unused Credit Facility fees, unused pro forma balance of 
  $345,192, fee of 0.15% ..........................................        518

Capitalized interest, actual amounts capitalized during
  the period ......................................................     (4,118)
                                                                      --------
  Pro forma interest expense ......................................   $ 91,505
                                                                      ========
</TABLE>

    The net change in interest expense is the result of the repayment of
borrowings on the Credit Facility of approximately $394,466 with the net
proceeds from the sale of Senior Debt Securities (see below) and approximately
$267,000 from the sale of Series A Preferred Shares, Series B Preferred Units
and sale of the Series C Preferred Units offset by borrowings on the Credit
Facility related to property acquisitions and the assumption of secured debt in
connection with the property acquisitions.

    In June 1998, the Operating Partnership issued $400,000 aggregate principal
amount of unsecured notes ("Senior Debt Securities") in an underwritten public
offering, the net proceeds of $394,466 were contributed to the Operating
Partnership and used to repay amounts outstanding under the Credit Facility. The
Senior Debt Securities mature in June 2008, June 2015 and June 2018 and bear
interest at a weighted average rate of 7.18%

    Also reflects the payment of pro forma Series A Preferred Stock dividends at
a dividend rate of 8.5%, the Series B Preferred Unit distributions as a
distribution rate of 8.625% and Series C Preferred Unit distributions at a
distribution rate of 8.75%.
