                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           SEPTEMBER 30, 1997 and 1996
                        (in thousands, except share data)

1.    ORGANIZATION AND BASIS OF PRESENTATION

      Spieker Properties, Inc.

      Spieker Properties, Inc. (the "Company") was organized in the state of
      Maryland on August 20, 1993, and commenced operations effective with the
      completion of its initial public offering ("IPO") on November 18, 1993.
      The Company qualifies as a real estate investment trust ("REIT") under the
      Internal Revenue Code of 1986 (the "Code"), as amended. As of September
      30, 1997, the Company owned an approximate 87.1 percent general
      partnership interest in Spieker Properties, L.P. (the "Operating
      Partnership"). The Company and the Operating Partnership are collectively
      referred to as the "Company."


2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Consolidation

      The Company's consolidated financial statements include the consolidated
      financial position of the Operating Partnership and its subsidiaries as of
      September 30, 1997, and December 31, 1996, and its consolidated results of
      operations for the three and nine months ended September 30, 1997 and 1996
      and its consolidated cash flows for the nine months ended September 30,
      1997 and 1996. All significant intercompany balances and transactions have
      been eliminated in the consolidated financial statements.

      Interim Financial Information

      The consolidated financial statements have been prepared pursuant to the
      rules and regulations of the Securities and Exchange Commission ("SEC")
      and, in management's opinion, include all adjustments necessary for a fair
      presentation of results for such interim periods. Certain information and
      note disclosures normally included in annual financial statements prepared
      in accordance with generally accepted accounting principles have been
      condensed or omitted pursuant to SEC rules or regulations; however, the
      Company believes that adequate disclosures have been made.

      The interim results for the three and nine months ended September 30, 1997
      and 1996, are not necessarily indicative of results for the full year. It
      is suggested that these financial statements be read in conjunction with
      the consolidated financial statements and notes thereto included in the
      Company's Annual Report on Form 10-K for the year ended December 31, 1996.

      Properties

      Properties are recorded at cost and are depreciated using the
      straight-line method over the estimated useful lives of the properties.
      The estimated lives are as follows:

<TABLE>
<S>                                                        <C>
         Land improvements and leasehold interests         18 to 40 years
         Buildings and improvements                        10 to 40 years
         Tenant improvements                               Term of the related lease
</TABLE>

      The cost of buildings and improvements includes the purchase price of the
      property or interests in property, legal fees, acquisition costs and
      interest, property taxes and other costs incurred during the period of
      construction.






                                       9

<PAGE>   10

      Expenditures for maintenance and repairs are charged to operations as
      incurred. Significant renovations or betterments which extend the economic
      useful life of assets are capitalized.

      Investments in real estate are stated at the lower of depreciated cost or
      estimated fair value. Fair value for financial reporting purposes is
      evaluated periodically by the Company on a property by property basis
      using undiscounted cash flow. If a potential impairment is identified, it
      is measured by the property's fair value based on either sales comparables
      or the net cash expected to be generated by the property, less estimated
      carrying costs (including interest) throughout the anticipated holding
      period, plus the estimated cash proceeds from the ultimate disposition of
      the property. To the extent that the carrying value exceeds the estimated
      fair value, a provision for decrease in net realizable value is recorded.
      Estimated fair value is not necessarily an indication of a property's
      current value or the amount that will be realized upon the ultimate
      disposition of the property. As of September 30, 1997, and December 31,
      1996, none of the carrying values of the properties exceeded their
      estimated fair values. As of September 30, 1997, and December 31, 1996,
      the properties are located primarily in California, Oregon and Washington.
      As a result of this geographic concentration, the operations of these
      properties could be adversely affected by a recession or general economic
      downturn in the areas where these properties are located.

      The Company owns four mortgage loans that are secured by real estate. Two
      of the four loans are with an affiliate of the Company (see note 3). The
      Company assesses possible impairment of these loans by reviewing the fair
      value of the underlying real estate. As of September 30, 1997, the fair
      value of the underlying real estate was in excess of the Company's book
      value of the mortgage loans.

      Construction in Progress

      Project costs clearly associated with the development and construction of
      a real estate project are capitalized as construction in progress. In
      addition, interest, real estate taxes and other costs are capitalized
      during the period in which activities necessary to get the property ready
      for its intended use are in progress.

      Ground Leases

      The land on which three of the Company's properties are located is owned
      by Stanford University and is subject to ground leases. The ground leases
      expire in 2039 or 2040 and, unless the leases are extended, the use of the
      land, together with all improvements, will revert back to Stanford
      University. The former owners of the three properties prepaid the ground
      leases through 2011, 2012 and 2017; thereafter, the Company will be
      responsible for the ground lease payments, as defined under the terms of
      the leases. These ground lease payments have been segregated from the
      total purchase price of the properties, capitalized as leasehold interests
      in the accompanying consolidated balance sheet, and are being amortized
      ratably over the terms of the related original prepayment periods (18 to
      24 years).

      In addition, the Company has entered into operating ground leases on
      certain land parcels with periods ranging from 16 to 53 years, certain of
      the operating ground leases contain purchase options.

      Cash and Cash Equivalents

      Highly liquid investments with an original maturity of three months or
      less when purchased are classified as cash equivalents.

      Deferred Financing and Leasing Costs

      Costs incurred in connection with financing or leasing are capitalized and
      amortized on a straight-line basis over the term of the related loan or
      lease for periods ranging from 1 to 30 years. Unamortized financing and
      leasing costs are charged to expense upon the early termination of the
      lease or upon early payment of financing.

      Fair Value of Financial Investments

      Based on the borrowing rates currently available to the Company, the
      carrying amount of debt approximates fair value. Cash and cash equivalents
      consist of demand deposits, certificates of deposit, overnight repurchase
      agreements, and investments in money market funds, with financial
      institutions. The carrying amount of cash and cash equivalents
      approximates fair value.

      Minority Interest

      Minority interest in the Company consists primarily of the individual
      Spieker Partners' limited partnership as well as other limited partners'
      interest in the Operating Partnership of approximately 12.9 percent and
      15.1 percent at September 30, 1997 and 1996, respectively.

      Revenues

      All leases are classified as operating leases. Rental income is recognized
      on the straight-line basis over the terms of the leases. Deferred rent
      receivable represents the excess of rental revenue recognized on a
      straight-line basis over cash received under the applicable lease
      provisions.

      Interest and Other Income

      Interest and other income includes interest income on cash, cash
      equivalents, investments in mortgages, and management fee income.

      Per share amounts for the Company are computed using the weighted average
      common shares outstanding (including convertible Class B Common Stock and
      convertible Class C Common Stock) during the period, including the
      dilutive effect of stock options. The weighted average common shares
      outstanding for the three and nine months ended September 30, 1997 and
      1996, are as follows:

</TABLE>


      Earnings used in the calculation are reduced by dividends owed to
      preferred stockholders.

      In March 1997, the Financial Accounting Standards Board issued Statement
      of Financial Accounting Standard No. 128 ("SFAS No. 128"), Earnings Per
      Share. SFAS No. 128 requires the disclosure of basic earnings per share
      and modifies existing guidance for computing fully diluted earnings per
      share. Under the new standard, basic earnings per share is computed as
      earnings divided by weighted average shares, excluding the dilutive
      effects of stock options and other potentially dilutive securities. The
      effective date of SFAS No. 128 is December 15, 1997, and early adoption is
      not permitted. The Company intends to adopt SFAS No. 128 during the
      quarter and year ended December 31, 1997. Had the provisions of SFAS No.
      128 been applied to the Company's results of operations for the three
      months ended September 30, 1997 and 1996, the Company's basic earnings per
      share would have been $.51 and $.27 per share, respectively, and its fully
      diluted earnings per share would have been $.50 and $.27 per share,
      respectively. Had the provisions of SFAS No. 128 been applied to the
      Company's results of operations for the nine months ended September 30,
      1997 and 1996, the





                                       11

<PAGE>   12
      Company's basic earnings per share would have been $1.61 and $.92 per
      share, respectively, and its fully diluted earnings per share would have
      been $1.59 and $.92 per share, respectively.

      Reclassifications

      Certain items in the 1996 financial statements have been reclassified to
      conform to the 1997 presentation.

      Use 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 assets and liabilities and
      disclosure of contingent assets and liabilities at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.


3.    TRANSACTIONS WITH AFFILIATES

      Receivable From Affiliates

      The receivable from affiliates at September 30, 1997, and December 31,

      retail and two office properties located in California. One of the retail
      properties and the two office properties are in contract and are scheduled
      to close by December 31, 1997. The divestiture of the remaining property
      is subject to identification of a purchaser, negotiation of acceptable
      terms and other customary conditions. The net carrying amount of property
      held for disposition as of September 30, 1997, is $49,239.


5.    DEBT

      Credit facility. The maximum amount available under the facility is

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONS AND RESULTS
        OF OPERATIONS

Statements contained in this Item 2, "Management's Discussion and Analysis of
Financial Conditions and Results of Operations," and elsewhere in this Quarterly
Report on Form 10-Q which are not historical facts may be forward-looking
statements. Such statements are subject to certain risks and uncertainties which
could cause actual results to differ materially from those projected, including,
but not limited to, those risks and special considerations set forth in the
Company's other SEC filings. Readers are cautioned not to place undue reliance
on these forward-looking statements which speak only as of the date hereof. The
Company undertakes no obligation to publicly release any revisions to these
forward-looking statements to reflect events or circumstances after the date
hereof or to reflect the occurrence of unanticipated events.

RESULTS OF OPERATIONS

The following comparison is of the Company's consolidated operations for the
three and nine month periods ended September 30, 1997, as compared to the
corresponding periods ended September 30, 1996.

Rental revenues for the third quarter of 1997 increased by $31.4 million or
61.4% to $82.5 million, as compared with $51.1 million for the quarter ended
September 30, 1996. Of this increase, $24.9 million was generated by properties
acquired during the first nine months of 1997 (the "1997 Acquisitions"). In the
third quarter of 1997 the Company acquired properties totaling 3.1 million
square feet for a total investment of $311.0 million. During the first nine
months of 1997 the Company acquired properties totaling 7.5 million square feet
for a total investment of $871.6 million. As used herein, the terms "invested"
and "total investment" represent the initial purchase price of acquisitions,
plus projected cost of certain repositioning and rehab capital expenditures
anticipated at the time of purchase. The properties acquired in the third
quarter were acquired on various dates throughout the quarter and, as such, a
full quarter's revenue and expenses was not recognized during the quarter.

$6.1 million of the rental revenue increase in the third quarter of 1997 was
generated by properties acquired during 1996. During 1996, the Company invested
$329.3 million to acquire properties totaling 4.7 million square feet (the "1996
Acquisitions").

$2.4 million of the increase in rental revenues is attributable to revenue
increases in properties owned at January 1, 1996, and still owned at September
30, 1997 (the "Core Portfolio"). This increase in the Core Portfolio is due to
increased rental rates realized on the renewal and re-leasing of
second-generation space and contractual rent increases in existing leases.
During the quarter ended September 30, 1997, the Company completed 204 lease
transactions for the renewal or re-leasing of 1.2 million square feet of
second-generation space. On average for the quarter, the new effective rates
were 24.7% higher than the expiring coupon rent. This brings the total
second-generation activity for the first nine months of 1997 to 603 completed
lease transactions for 3.6 million square feet at a 22.5% increase in effective
rates, over expiring coupon rents.

$2.0 million of the rental revenue increase in the third quarter of 1997 was
generated by properties developed by the Company (the "Developments"). The
Developments include both properties completed and added to the Company's
portfolio of stabilized properties during 1996 and 1997, as well as properties
currently under development. During the nine months ended September 30, 1997,
seven properties totaling 1.6 million square feet have been completed and added
to the Company's portfolio of stabilized properties. The total cost of these
properties, including the estimated cost to complete initial tenant
improvements, is $59.2 million. The Company also has a current development
pipeline of 3.2 million square feet representing a total projected cost of
$287.0 million. Certain of the properties in the development pipeline are shell
complete and partially occupied.

The increases in rental revenue are partially offset by a decrease of $4.0
million attributable to the disposition of properties which were owned by the
Company during the quarter ended September 30, 1996 (the "Property
Dispositions").

Rental revenues for the nine month period ended September 30, 1997, increased by
$79.3 million or 55.8% to $221.4 million as compared to $142.1 million for the
same period ended September 30, 1996. $50.2 million and $25.8 million,
respectively, of this increase was attributable to the 1997 and 1996
Acquisitions, $6.1 million relates to the Core Portfolio, $5.7 million is
attributable to the Developments, with the remainder attributable to a $8.5
million decrease from Property Dispositions.

As a result of the 1997 Acquisitions, the 1996 Acquisitions, and the
Developments, the Company's rentable square footage, not including retail
properties, increased by 11.0 million square feet or 60.8% to 29.1 million
square feet on September 30, 1997, from 18.1 million on September 30, 1996. At
September 30, 1997, the portfolio of stabilized properties was 95.1% occupied.
By property type, the office portfolio was 95.9% occupied and the industrial
portfolio was 94.5% occupied.

Interest and other income increased by $.3 million and $1.8 million or 27.3% and
60.0% for the three and nine month periods ended September 30, 1997, over the
same respective periods ended September 30, 1996. The net increase in interest
and other income is due to higher average cash balances of $30.7 million and
$49.2 million for the three and nine month periods ended September 30, 1997, as
compared to $14.7 million and $11.1 million for the corresponding periods in
1996.

Rental expenses increased by $7.8 million or 81.3% for the three months ended
September 30, 1997, as compared with the same period in 1996. Real estate taxes
increased by $2.0 million or 50.0% for the three months ended September 30,
1997, as compared with the same period in 1996. The overall increase in rental
expenses and real estate taxes (collectively referred to as "property operating
expenses") is primarily a result of the growth in the total square footage of
the Company's portfolio of properties. Of the total $9.8 million increase in
property operating expenses $8.0 million is attributable to the 1997
Acquisitions, $2.1 million is attributable to the 1996 Acquisitions, $0.4
million is attributable to the Developments, and a $0.7 million decrease
attributable to the Property Dispositions. The Core Portfolio remained
essentially unchanged for the comparable quarters. On a percentage basis,
property operating expenses were 28.4% and 26.6% of rental revenues for the
quarters ended September 30, 1997, and September 30, 1996, respectively. The
increase in property operating expenses as a percentage of rental revenues is
attributable to the increased percentage of office properties in the Company's
portfolio. For the quarter ended September 30, 1997, 62.0% of the Company's net
operating income (rental revenues less property operating expenses) was
generated by office properties as compared with 45.6% during the same period in
1996.

In December 1996, the Company announced the strategic decision to divest itself
of its retail properties and focus exclusively on office and industrial
properties. As such, the following analysis of the office and industrial
properties (i.e. non-retail properties) is presented: Rental revenues net of
property operating expenses (referred to as "property operating income")
increased by $24.9 million or 76.6% to $57.4 million, as compared to $32.5
million for the quarter ended September 30, 1996. Of this increase, $16.9
million and $4.0 million relates to the 1997 and 1996 Acquisitions $2.4 million
is attributable to the Core Portfolio, and $1.6 million is attributable to the
Developments. For the nine month period ended September 30, 1997, property
operating income increased by $60.5 million or 65.8% from $92.0 million to
$152.5 million at September 30, 1997. $33.7 million and $17.4 million related to
the 1997 and 1996 Acquisitions, $5.0 million is related to the Core Portfolio,
and $4.4 million is attributed to the Developments.

For the nine month period ended September 30, 1997, rental expenses increased by
$20.1 million from $24.4 million for the nine months ended September 30, 1996.
This represents a 82.4% increase year over year. Real estate taxes increased by
$5.8 million or 51.3% to $17.1 million for the first three quarters of 1997 as
compared to $11.3 million for the same period in 1996. The total increase in the
property operating expenses is attributable to a $16.5 million increase for the
1997 Acquisitions, a $8.4 million increase for the 1996 Acquisitions, a $1.3
million increase for the Developments, a $1.1 million increase in the Core
Portfolio, and a $1.4 reduction attributable to the Property Dispositions. On a
percentage basis property operating expenses were 27.8% and 25.1% of rental
revenues for the nine months ended September 30, 1997, and 1996, respectively.








                                       17

Interest expense increased by $6.4 million or 65.3% to $16.2 million for the
three months ended September 30, 1997, from $9.8 million for the same period in
1996. For the nine month period ended September 30, 1997, interest expense
increased by $14.5 million or 54.9% to $40.9 million from $26.4 million for the
same period in 1996. These increases in interest expense are due to increases in
the total average outstanding debt balances. The average outstanding debt for
the three months ended September 30, 1997, and 1996 was $981.3 million and
$557.3 million respectively. The average balance outstanding for the nine months
ended September 30, 1997, was $823.6 million and $520.5 million for the same
period in 1996. The increases in the average outstanding debt balances are
consistent with the increases in the size of the Company's portfolio of
properties.

Depreciation and amortization expenses increased by $3.4 million and $9.1
million or 34.0% and 33.2% for the three and nine month periods ended September
30, 1997, as compared with the same periods in 1996, due to the 1997 and 1996
Acquisitions and the completed Developments.

General and administrative expenses and other expenses increased by $1.0 million
and $2.8 million for the three and nine month periods ended September 30, 1997,
respectively, as compared with the same periods in 1996, primarily as a result
of the increased number of employees. On a percentage basis, general and
administrative expenses were 4.5% and 4.7% of rental revenues for the three and
nine month periods ended September 30, 1997, respectively, as compared with 5.3%
for both periods in 1996.

During the third quarter of 1997, the Company disposed of a retail property
resulting in a gain on disposition of $2.0 million. In addition, the Company
disposed of one industrial property and one parking lot resulting in a gain of
$1.9 million. This brings the total gain on disposition of property for the
first three quarters of 1997 to $18.1 million on ten properties.

Net income before minority interests and disposition of property increased by
$11.0 million or 68.3% to $27.1 million for the three month period ended
September 30, 1997, from $16.1 million for the same period in 1996. For the nine
month period ended September 30, 1997, net income before minority interests and
disposition of property increased by $28.8 million or 59.8% to $77.0 million,
from $48.2 million for the same period in 1996. The increase in net income is
principally due to the 1997 and 1996 Acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

For the nine-month period ended September 30, 1997, cash provided by operating
activities increased by $36.8 million or 40.2% to $128.4 million, as compared to
$91.6 million for the same period in 1996. The increase is primarily due to the
increase in net income resulting from the 1996 and 1997 Acquisitions. Cash used
for investing activities increased by $524.7 million or 194.3% to $794.7 million
for the first nine months of 1997, as compared to $270.0 million for the same
period in 1996. The increase is attributable to the Company's ongoing
acquisition and development of suburban office and industrial properties. Cash
provided by financing activities increased by $480.4 million or 245.9% to $675.8
million for the first nine months of 1997, as compared to $195.4 million for the
same period in 1996. During the first nine months of 1997, cash provided by
financing activities consisted, primarily, of $374.8 million in net proceeds
from the sale of Common Stock, $292.2 million in net proceeds from the issuance
of unsecured investment grade notes, net borrowings of $99.0 million on the line
of credit and a net increase of $38.9 million in mortgage loans outstanding.
Additionally, payments of distributions increased by $18.0 million to $78.5
million for the first nine months of 1997, as compared with $60.5 million for
the same period in 1996. The increase is due to the greater number of shares
outstanding and a 9.3% increase in the distribution rate.

The principal sources of funding for acquisitions, development, expansion and
renovation of the properties are an unsecured line of credit, public and
privately placed equity financing, public unsecured debt financing, the issuance
of partnership units in the Operating Partnership, the assumption of secured
debt on properties acquired and cash flow provided by operations. The Company
believes that its liquidity and capital resources are adequate to continue to
meet liquidity requirements for the foreseeable future.

At September 30, 1997, the Company had no material commitments for capital
expenditures related to the renewal or re-leasing of space. The Company believes
that the cash provided by operations and its line of







                                       18
<PAGE>   19


credit provide sufficient sources of liquidity to fund capital expenditure costs
associated with the renewal or re-leasing of space.

The Company has a $250.0 million unsecured line of credit facility (the
"Facility") with interest at London Interbank Offered Rates ("LIBOR") plus .80%.
The Facility matures in August 2001. This increased facility has a competitive
bid option that allows the Company to request bids from the Lenders for advances
up to $150.0 million. At September 30, 1997, the Company had $138.0 million
outstanding under the Facility.

On January 19, 1996, the Company issued $100.0 million of investment grade rated
unsecured notes. The notes carry an interest rate of 6.90%, were priced to yield
6.97%, and mature on January 15, 2004. Net proceeds of $98.9 million were used
to repay borrowings on the unsecured line of credit. In June 1996, the Company
commenced a $200.0 million medium-term note program. In July 1996, the Company
issued $100.0 million of 8.00% medium-term notes due July 19, 2005, and $50.0
million of 7.58% medium-term notes due December 17, 2001 (the "July Notes"). The
net proceeds of $149.2 million from the issuance of the July Notes were used to
repay borrowings on the line of credit and to fund ongoing acquisition and
development projects. In December 1996, the Company issued $100.0 million of
7.125% investment grade rated unsecured notes, priced to yield 7.14% and
maturing on December 1, 2006, and $25.0 million of 7.875% investment grade rated
unsecured notes, priced to yield 7.91% and maturing on December 1, 2016. The net
proceeds of $123.9 million were used to pay down borrowings on the line of
credit and to fund the ongoing acquisition and development of properties. On
July 14, 1997, the Company issued $150.0 million of investment grade rated
unsecured notes. The notes carry an interest rate of 7.125%, were priced to
yield 7.183%, and mature on July 1, 2009. On September 29, 1997, the Company
issued $150.0 million of investment grade rated unsecured debentures. The
debentures carry an interest rate of 7.5%, were priced to yield 7.57% and mature
on October 1, 2027. Net proceeds from the July 1997 and September 1997 unsecured
debt securities of $292.2 million were used to repay borrowings on the unsecured
line of credit and to fund the ongoing acquisition and development of
properties.

As of September 30, 1997, the Company had $935.0 million of investment grade
rated unsecured debt securities outstanding. The debt securities have interest
rates which vary from 6.65% to 8.00%, and various maturity dates which range
from 2000 to 2027. As of September 30, 1997, $50.0 million of debt securities
remained available for issuance under the medium-term note program.

In addition to the Unsecured Notes and the Facility, the Company has $84.9
million of secured indebtedness (the "Mortgages") at September 30, 1997. The
Mortgages have interest rates varying from 7.37% to 9.75% and maturity dates
from 1997 to 2012. The Mortgages are secured by a first or second deed of trust
on the related properties and generally require monthly principal and interest
payments. The Company also has $6.8 million of assessment bonds outstanding as
of September 30, 1997.

In January 1997, the Company sold 11,500,000 shares of Common Stock (including
1,500,000 shares sold to the underwriters in the exercise of their
over-allotment option in February 1997) through an underwritten public offering
at $34.50 per share. The net proceeds of $374.8 million were used to purchase
properties during the first quarter of 1997, many of which were under contract
or letter of intent at the time of the offering, and to repay indebtedness.
Also, in January 1997, the Company and the Operating Partnership filed a shelf
registration statement (the "January 1997 Shelf Registration Statement") with
the SEC which registered $500.0 million of equity securities of the Company and
$500.0 million of debt securities of the Operating Partnership and became
effective in January 1997.

In September 1997, the Company and the Operating Partnership filed a shelf
registration (the "September 1997 Shelf Registration Statement") with the SEC
which registered $500.0 million of equity securities of the Company and $500.0
million of debt securities of the Operating Partnership and became effective in
October 1997.

On October 10, 1997, the Company sold 6,000,000 shares of Series C Cumulative
Redeemable Preferred Stock for $25.00 per share. Dividends are payable at an
annual rate of 7.88% of the liquidation preference of







                                       19

<PAGE>   20

$150,000. Net proceeds of $146,135 were used principally to repay borrowings on
the unsecured line of credit and to fund ongoing acquisition and development of
property.

In November 1997, the Company sold 11,500,000 shares of Common Stock (including
1,500,000 shares sold to the underwriters in the exercise of their
over-allotment option) through an underwritten public offering at $38.875 per
share. The net proceeds of $425,027 were used to repay indebtedness and to
purchase properties which were under contract at the time of the offering.

After completion of the equity and debt offerings, the Company has the capacity
pursuant to the September 1997 Registration Statement to issue up to
approximately $402.9 million in equity securities and the Operating Partnership
has the capacity pursuant to the January 1997 Shelf Registration Statement and
the September 1997 Registration Statement to issue up to $815.0 million in debt
securities (including the $50.0 million of medium-term notes available under the
Company's existing medium-term note program).

FUNDS FROM OPERATIONS

The Company considers Funds from Operations to be a useful financial measure of
the operating performance of an equity REIT because, together with net income
and cash flows, Funds from Operations provides investors with an additional
basis to evaluate the ability of a REIT to incur and service debt and to fund
acquisitions, developments, and other capital expenditures. Funds from
Operations does not represent net income or cash flows from operations as
defined by generally accepted accounting principles ("GAAP") and Funds from
Operations should not be considered as an alternative to net income as an
indicator of the Company's operating performance or as an alternative to cash
flows as a measure of liquidity. Funds from Operations does not measure whether
cash flow is sufficient to fund all of the Company's cash needs including
principal amortization, capital improvements, and distributions to stockholders.
Funds from Operations does not represent cash flows from operating, investing,
or financing activities as defined by GAAP. Further, Funds from Operations as
disclosed by other REITs may not be comparable to the Company's calculation of
Funds from Operations, as described below.

Pursuant to the National Association of Real Estate Investment Trusts ("NAREIT")
revised definition of Funds from Operations, beginning with the quarter ended
March 31, 1996, the Company calculated Funds from Operations by adjusting net
income before minority interest, calculated in accordance with GAAP, for certain
non-cash items, principally the amortization and depreciation of real property
and for dividends on shares and other equity interests that are not convertible
into shares of Common Stock. The Company does not add back the depreciation of
corporate items, such as computers or furniture and fixtures, or the
amortization of deferred financing costs or debt discount. However, the Company
includes an adjustment for the straight-lining of rent under GAAP, as management
believes this presents a more meaningful picture of rental income over the
reporting period.

Funds from Operations per share is calculated based on weighted average shares
equivalents outstanding, assuming the conversion of all shares of Series A
Preferred Stock, Class B Common Stock, Class C Common Stock and all partnership
units in the Operating Partnership into shares of Common Stock, and including
the dilutive effect of stock options. Assuming such conversion, the average
number of shares outstanding for the three and nine months ended September 30,
1997, are 56,458,964 and 55,186,005, respectively, and 43,497,648 and 42,049,446
for the same periods in 1996.

                            SPIEKER PROPERTIES, INC.
                             ARTICLES SUPPLEMENTARY


        SPIEKER PROPERTIES, INC., a Maryland corporation, having its principal
office in the City of Baltimore, Maryland (the "Corporation"), hereby certifies
to the Maryland State Department of Assessments and Taxation that:

        FIRST: Pursuant to authority expressly vested in the Board of Directors
of the Corporation by the Charter of the Corporation, the Board of Directors has
duly reclassified 6,000,000 shares of the Common Stock (par value $.0001 per
share) of the Corporation into 6,000,000 shares of a class designated as Series
C Cumulative Redeemable Preferred Stock (par value $.0001 per share) of the
Corporation ("Series C Preferred Stock") and has provided for the issuance of
such shares.

        SECOND: The reclassification increases the number of shares classified
as Series C Preferred Stock from no shares immediately prior to the
reclassification to 6,000,000 shares immediately after the reclassification. The
reclassification decreases the number of shares classified as Common Stock (par
value $.0001 per share) from 660,500,000 shares immediately prior to the
reclassification to 654,500,000 shares immediately after the reclassification.

        THIRD: Subject in all cases to the provisions of Article NINTH of the
Charter of the Corporation with respect to Excess Stock, the following is a
description of the preferences, conversion and other rights, voting powers,
restrictions, limitations as to dividends, qualifications and terms and
conditions of redemption of Series C Preferred Stock of the Corporation:

               1.     DESIGNATION AND AMOUNT.

                      The designation of Series C Preferred Stock described in
        Article FIRST hereof shall be "Series C Cumulative Redeemable Preferred
        Stock (par value $.0001 per share)." The number of shares of Series C
        Preferred Stock to be authorized shall be 6,000,000. The Series A
        Preferred Stock, par value $.0001 per share ("Series A Preferred Stock")
        and the Series B Cumulative Redeemable Preferred Stock, par value $.0001
        per share ("Series B Preferred Stock"), of the Corporation rank on a
        parity as to dividends and amounts upon liquidation.

               2.     DIVIDENDS AND DIVIDEND PROVISIONS.

                      (a) Subject to the rights of series of Preferred Stock
        which may from time to time come into existence, holders of Series C
        Preferred Stock shall be entitled to receive, when and as declared by
        the Board of Directors, out of funds legally available for the payment
        of dividends, cumulative preferential cash dividends at the rate of
        $1.96875 per annum per share. Such dividends shall be cumulative from
        the date of original issue and shall be payable quarterly in arrears on
        the last day of January, April, July and October or, if not a business
        day, the next succeeding business day (each, a "Dividend Payment Date").
        The first dividend, which will be due on October 31, 1997, will be for
        less than a full quarter. Such first dividend and any dividend payable
        on Series C Preferred Stock for any partial dividend period will be
        computed on the basis of a 360-day year consisting of twelve 30-day
        months. Dividends will be payable to holders of record as they appear in
        the records of the Corporation at the close of business on the
        applicable record date, which shall be on such date designated by the
        Board of Directors of the Corporation for the payment of dividends that
        is not more than 50 nor less than 10 days prior to such Dividend Payment
        Date (each, a "Dividend Record Date").




                                      - 1 -



<PAGE>   2
                      (b) Dividends on Series C Preferred Stock will accrue
        whether or not the Corporation has earnings, whether or not there are
        funds legally available for the payment of such dividends and whether or
        not such dividends are declared. No interest, or sum of money in lieu of
        interest, shall be payable in respect of any dividend payment or
        payments on Series C Preferred Stock which may be in arrears. Holders of
        the Series C Preferred Stock will not be entitled to dividends in excess
        of the full cumulative dividends as described above.

                      (c) If, for any taxable year, the Corporation elects to
        designate as "capital gain dividends" (as defined in Section 857 of the
        Internal Revenue Code of 1986, as amended, or any successor revenue code
        or section (the "Code")) any portion (the "Capital Gains Amount") of the
        total distributions (as determined for federal income tax purposes) paid
        or made available for the year to holders of all classes of capital
        stock (the "Total Distributions"), then the portion of the Capital Gains
        Amount that shall be allocable to holders of Series C Preferred Stock
        shall be in the same portion that the Total Distributions paid or made
        available to the holders of Series C Preferred Stock for the year bears
        to the Total Distributions.

                      (d) If any shares of Series C Preferred Stock are
        outstanding, no dividends shall be declared or paid or set apart for
        payment on any shares of series of capital stock of the Corporation
        ranking, as to dividends, on a parity with or junior to Series C
        Preferred Stock for any period unless full cumulative dividends have
        been or contemporaneously are declared and paid or declared and a sum
        sufficient for the payment thereof set apart for such payments on shares
        of Series C Preferred Stock for all past dividend periods and the then
        current dividend period. When dividends are not paid in full (or a sum
        sufficient for such full payment is not set apart) upon the shares of
        Series C Preferred Stock and the shares of any other series of capital
        stock ranking on parity as to dividends with shares of Series C
        Preferred Stock, all dividends declared upon shares of Series C
        Preferred Stock and any other series of capital stock ranking on a
        parity as to dividends with Series C Preferred Stock shall be declared
        pro rata so that the amount of dividends declared per share on Series C
        Preferred Stock and such other series of capital stock shall in all
        cases bear to each other the same ratio that accrued dividends per share
        on Series C Preferred Stock and such other series of capital stock bear
        to each other.

                      (e) Except as provided in Section 2(d), unless full
        cumulative dividends on shares of Series C Preferred Stock have been or
        contemporaneously are declared and paid or declared and a sum sufficient
        for the payment thereof set apart for payment for all past dividend
        periods and the then current dividend period, no dividends (other than
        in shares of Common Stock or other capital stock ranking junior to
        Series C Preferred Stock as to dividends and amounts upon liquidation)
        shall be declared or paid or set aside for payment or other dividend
        shall be declared or made upon the shares of Common Stock, Class B
        Common Stock, Class C Common Stock, Series A Preferred Stock, Series B
        Preferred Stock or any other capital stock of the Corporation ranking
        junior to or on a parity with Series C Preferred Stock as to dividends
        or amounts upon liquidation, nor shall any shares of Common Stock, Class
        B Common Stock, Class C Common Stock, Series A Preferred Stock, Series B
        Preferred Stock or any other capital stock of the Corporation ranking
        junior to or on a parity with Series C Preferred Stock as to dividends
        or amounts upon liquidation be redeemed, purchased or otherwise acquired
        for any consideration (or any moneys be paid to or made available for a
        sinking fund for the redemption of any such capital stock) by the
        Corporation (except by conversion into or exchange for other capital
        stock of the Corporation ranking junior to Series C Preferred Stock as
        to dividends and amounts upon liquidation).

<PAGE>   3
                      (f) Any dividend payment made on shares of Series C
        Preferred Stock shall first be credited against the earliest accrued but
        unpaid dividend due with respect to shares of Series C Preferred Stock
        which remains payable.

               3.     LIQUIDATION RIGHTS.

                      (a) Subject to the rights of series of Preferred Stock
        which may from time to time come into existence, upon any voluntary or
        involuntary liquidation, dissolution or winding up of the affairs of the
        Corporation, then, before any distribution or payment shall be made to
        the holders of any shares of Common Stock or any other class or series
        of capital stock of the Corporation ranking junior to Series C Preferred
        Stock in the distribution of assets upon any liquidation, dissolution or
        winding up of the affairs of the Corporation, the holders of shares of
        Series C Preferred Stock shall be entitled to receive out of assets of
        the Corporation legally available for distribution to stockholders,
        liquidation distributions in the amount of the liquidation preference of
        $25.00 per share, plus an amount equal to all dividends accrued and
        unpaid thereon. After payment of the full amount of the liquidating
        distributions to which they are entitled, the holders of shares of
        Series C Preferred Stock will have no right or claim to any of the
        remaining assets of the Corporation, including the Series A Preferred
        Stock and the Series B Preferred Stock. In the event that, upon any such
        voluntary or involuntary liquidation, dissolution or winding up of the
        affairs of the Corporation, the available assets of the Corporation are
        insufficient to pay the amount of the liquidation distributions on all
        outstanding shares of Series C Preferred Stock and the corresponding
        amounts payable on all shares of other classes or series of capital
        stock of the Corporation ranking on a parity with Series C Preferred
        Stock in the distribution of assets upon any liquidation, dissolution or
        winding up of the affairs of the Corporation ("Parity Stock"), then the
        holders of shares of Series C Preferred Stock and Parity Stock shall
        share ratably in any such distribution of assets in proportion to the
        full liquidating distributions to which they would otherwise be
        respectively entitled.

                      (b) A consolidation or merger of the Corporation with or
        into any other entity or entities, or a sale, lease, conveyance or
        disposition of all or substantially all of the assets of the Corporation
        or the effectuation by the Corporation of a transaction or series of
        related transactions in which more than 50% of the voting power of the
        Corporation is disposed of, shall not be deemed to be a liquidation,
        dissolution or winding up of the affairs of the Corporation within the
        meaning of this Section 3.

               4.     REDEMPTION.

                      (a) Shares of Series C Preferred Stock are not redeemable
        prior to October 10, 2002. On and after October 10, 2002, the
        Corporation at its option upon not less than 30 nor more than 90 days'
        written notice may redeem outstanding shares of Series C Preferred
        Stock, in whole or in part, at any time or from time to time, for cash
        at a redemption price of $25.00 per share, plus an amount equal to all
        dividends accrued and unpaid thereon to the date fixed for redemption,
        without interest. The redemption price of shares of Series C Preferred
        Stock (other than the portion thereof consisting of accrued and unpaid
        dividends) is payable solely out of proceeds from the sale of other
        capital stock of the Corporation, which may include Common Stock,
        Preferred Stock, depositary shares, interests, participations or other
        ownership interests in the Corporation however designated (other than
        debt securities converted into or exchangeable for capital stock), and
        any rights, warrants or options to purchase any thereof. Holders of
        shares of Series C Preferred Stock to be redeemed shall surrender such
        shares of Series C Preferred Stock at the place designated in such
        notice and shall be entitled to the redemption price and any accrued and
        unpaid dividends payable upon such redemption following such surrender.
        If fewer than all of the




                                      - 3 -


<PAGE>   4
        outstanding shares of Series C Preferred Stock are to be redeemed, the
        number of shares to be redeemed will be determined by the Corporation
        and such shares may be redeemed pro rata from the holders of record of
        such shares in proportion to the number of such shares held by such
        holders (with adjustments to avoid redemption of fractional shares) or
        by lot in a manner determined by the Corporation.

                      (b) Unless full cumulative dividends on all shares of
        Series C Preferred Stock and Parity Stock shall have been or
        contemporaneously are declared and paid or declared and a sum sufficient
        for the payment thereof set apart for payment for all past dividend
        periods and the then current dividend period, no shares of Series C
        Preferred Stock or Parity Stock shall be redeemed unless all outstanding
        shares of Series C Preferred Stock and Parity Stock are simultaneously
        redeemed; provided, however, that the foregoing shall not prevent the
        purchase or acquisition of shares of Series C Preferred Stock or Parity
        Stock pursuant to a purchase or exchange offer made on the same terms to
        holders of all outstanding shares of Series C Preferred Stock or Parity
        Stock, as the case may be. Furthermore, unless full cumulative dividends
        on all outstanding shares of Series C Preferred Stock and Parity Stock
        have been or contemporaneously are declared and paid or declared and a
        sum sufficient for the payment thereof set apart for payment for all
        past dividend periods and the then current dividend period, the
        Corporation shall not purchase or otherwise acquire directly or
        indirectly any shares of Series C Preferred Stock or Parity Stock
        (except by conversion into or exchange for shares of capital stock of
        the Corporation ranking junior to Series C Preferred Stock and Parity
        Stock as to dividends and amounts upon liquidation).

                      (c) Notice of redemption will be mailed at least 30 days
        but not more than 90 days before the redemption date to each holder of
        record of shares of Series C Preferred Stock at the address shown on the
        stock transfer books of the Corporation. Each notice shall state: (i)
        the redemption date; (ii) the number of shares of Series C Preferred
        Stock to be redeemed; (iii) the redemption price per share; (iv) the
        place or places where certificates for shares of Series C Preferred
        Stock are to be surrendered for payment of the redemption price; and (v)
        that dividends on shares of Series C Preferred Stock will cease to
        accrue on such redemption date. If fewer than all shares of Series C
        Preferred Stock are to be redeemed, the notice mailed to each such
        holder thereof shall also specify the number of shares of Series C
        Preferred Stock to be redeemed from each such holder. If notice of
        redemption of any shares of Series C Preferred Stock has been given and
        if the funds necessary for such redemption have been set aside by the
        Corporation in trust for the benefit of the holders of shares of Series
        C Preferred Stock so called redemption, then from and after the
        redemption date, dividends will cease to accrue on such shares of Series
        C Preferred Stock, such shares of Series C Preferred Stock shall no
        longer be deemed outstanding and all rights of the holders of such
        shares will terminate, except the right to receive the redemption price.

                      (d) The holders of shares of Series C Preferred Stock at
        the close of business on a Dividend Record Date will be entitled to
        receive the dividend payable with respect to such shares of Series C
        Preferred Stock on the corresponding Dividend Payment Date
        notwithstanding the redemption thereof between such Dividend Record Date
        and the corresponding Dividend Payment Date or the Corporation's default
        in the payment of the dividend due. Except as provided above, the
        Corporation will make no payment or allowance for unpaid dividends,
        whether or not in arrears, on shares of Series C Preferred Stock which
        have been called for redemption.

                      (e) Series C Preferred Stock will not be subject to any
        sinking fund or mandatory redemption, except as provided in Article
        NINTH of the Charter of the Corporation.

               5.     VOTING RIGHTS.

                      (a) Except as indicated in this Section 5, or except as
        otherwise from time to time required by applicable law, the holders of
        shares of Series C Preferred Stock will have no voting rights.

                      (b) If six quarterly dividends (whether or not
        consecutive) payable on shares of Series C Preferred Stock or any Parity
        Stock are in arrears, whether or not earned or declared, the number of
        directors then constituting the Board of Directors of the Corporation
        will be increased by two, and the holders of shares of Series C
        Preferred Stock, voting together as a class with the holders of shares
        of any other series of Parity Stock entitled to such voting rights (any
        such other series, the "Voting Preferred Stock"), will have the right to
        elect two additional directors to serve on the Corporation's Board of
        Directors at any annual meeting of stockholders or a properly called
        special meeting of the holders of Series C Preferred Stock and such
        other Voting Preferred Stock until all such dividends have been declared
        and paid or set aside for payment. The term of office of all directors
        so elected will terminate with the termination of such voting rights.

                      (c) The approval of a majority of the outstanding Series C
        Preferred Stock and all other series of Voting Preferred Stock similarly
        affected, voting as a single class is required in order to (i) enter
        into a share exchange that affects shares of Series C Preferred Stock or
        the Voting Preferred Stock, or consolidate with or merge the Corporation
        with or into any other corporation, unless in each such case each share
        of Series C Preferred Stock and Voting Preferred Stock remains
        outstanding without a material adverse change to its terms and rights or
        is converted into or exchanged for preferred stock of the surviving
        entity having preferences, conversion and other rights, voting powers,
        restrictions, limitations as to dividends, qualifications and terms or
        conditions of redemption thereof identical to that of a share of Series
        C Preferred Stock or the Voting Preferred Stock, or (ii) authorize,
        reclassify, create, or increase the authorized amount of any class of
        stock having rights senior to Series C Preferred Stock or the Voting
        Preferred Stock with respect to the payment of dividends or amounts upon
        liquidation, dissolution or winding up of the affairs of the
        Corporation. However, the Corporation may create additional classes of
        Parity Stock and capital stock ranking junior to Series C Preferred
        Stock as to dividends or amounts upon liquidation, dissolution or
        winding up of the affairs of the Corporation ("Junior Stock"), increase
        the authorized number of shares of Parity Stock and Junior Stock and
        issue additional series of Parity Stock and Junior Stock without the
        consent of any holder of Series C Preferred Stock.

                      (d) The approval of two-thirds of the outstanding Series C
        Preferred Stock and all other series of Voting Preferred Stock similarly
        affected, voting as a single class, is required in order to amend the
        Corporation's Articles Supplementary or Charter to affect materially and
        adversely the rights, preferences or voting power of the holders of
        shares of Series C Preferred Stock or the Voting Preferred Stock.

                      (e) Except as provided above and as required by law, the
        holders of Series C Preferred Stock are not entitled to vote on any
        merger or consolidation involving the Corporation, on any share exchange
        or on a sale of all or substantially all of the assets of the
        Corporation.

               6.     CONVERSION.

                      The shares of Series C Preferred Stock are not convertible
        into or exchangeable for any other property or securities of the
        Corporation, except that each share of Series C Preferred Stock is
        exchangeable into Excess Stock as provided in Article NINTH of the
        Charter of the Corporation.

               7.     STATUS OF REDEEMED OF REACQUIRED STOCK.

                      In the event any shares of Series C Preferred Stock shall
        be redeemed pursuant to Section 4 hereof or reacquired, the shares so
        redeemed or reacquired shall revert to the status of authorized but
        unissued shares of Series C Preferred Stock available for future
        issuance and reclassification by the Corporation.

               (5) The Place of Payment where the principal of and interest on
        the Notes shall be payable and Notes may be surrendered for the
        registration of transfer or exchange shall be the Corporate Trust Office
        of the Trustee in St. Paul, Minnesota. The place where notices or
        demands to or upon the Issuer in respect of the Notes and the Indenture
        may be served shall be the corporate trust office of the Trustee at One
        California Street, Suite 400, San Francisco, California 94111.

               (6) (A) The Notes may be redeemed at any time at the option of
        the Issuer, in whole or from time to time in part, at a redemption price
        equal to the sum of (i) the principal amount of the Notes (or portion
        thereof) being redeemed plus accrued interest thereon to the redemption
        date and (ii) the Make-Whole Amount (as defined below), if any, with
        respect to such Notes (or portion thereof) (the "Redemption Price").

                      If notice has been given as provided in the Indenture and
        funds for the redemption of any Notes (or any portion thereof) called
        for redemption shall have been made available on the redemption date
        referred to in such notice, such Notes (or any portion thereof) will
        cease to bear interest on the date fixed for such redemption specified
        in such notice and the only right of the Holders of the Notes will be to
        receive payment of the Redemption Price, with respect to such Notes or
        portion thereof so redeemed.

                      Notice of any optional redemption of any Notes (or any
        portion thereof) will be given to Holders at their addresses, as shown
        in the security register for the Notes, not more than 60 nor less than
        30 days prior to the date fixed for redemption. The notice of redemption
        will specify, among other items, the Redemption Price and the principal
        amount of the Notes held by such Holder to be redeemed. On the third
        Business Day preceding the date notice of redemption is given, the
        Company will notify the Trustee of the Redemption Price and the Trustee
        may rely and shall be fully protected in acting upon the determination
        of the Company as to such Redemption Price.

                      The Issuer will notify the Trustee in writing at least 45
        days prior to giving notice of redemption (or such shorter period as is
        satisfactory to the Trustee in its sole discretion) of the aggregate
        principal amount of Notes to be redeemed and their redemption date. If
        less than all the Notes are to be redeemed at the option of the Issuer,
        the Trustee shall select by lot, the Notes to be redeemed in whole or in
        part.

                      In the event of redemption of the Notes in part only, a
        new Note for the amount of the unredeemed portion thereof shall be
        issued in the name of the Holder thereto, upon cancellation thereof.

                      (B) As used herein:

                      "Make-Whole Amount" means, in connection with any optional
        redemption or accelerated payment of any Notes, the excess, if any, of
        (i) the aggregate present value as of the date of such redemption or
        accelerated payment of each dollar of




                                       -3-


<PAGE>   4
        principal being redeemed or paid and the amount of interest (exclusive
        of interest accrued to the date of redemption or accelerated payment)
        that would have been payable in respect of each such dollar if such
        redemption or accelerated payment had not been made, determined by
        discounting, on a semi-annual basis, such principal and interest at the
        Reinvestment Rate (determined on the third Business Day preceding the
        date such notice of redemption is given or declaration of acceleration
        is made) from the respective dates on which such principal and interest
        would have been payable if such redemption or accelerated payment had
        not been made, over (ii) the aggregate principal amount of the Notes
        being redeemed or paid.

                      "Reinvestment Rate" means 0.25% plus the arithmetic mean
        of the yields under the respective heading "Week Ending" published in
        the most recent Statistical Release under the caption "Treasury Constant
        Maturities" for the maturity (rounded to the nearest month)
        corresponding to the remaining life to maturity, as of the payment date
        of the principal being redeemed or paid. If no maturity exactly
        corresponds to such maturity, yields for the two published maturities
        most closely corresponding to such maturity shall be calculated pursuant
        to the immediately preceding sentence and the Reinvestment Rate shall be
        interpolated or extrapolated from such yields on a straight-line basis,
        rounding in each of such relevant periods to the nearest month. For the
        purpose of calculating the Reinvestment Rate, the most recent
        Statistical Release published prior to the date of determination of the
        Make-Whole Amount shall be used.

                      "Statistical Release" means the statistical release
        designated "H.15(519)" or any successor publication which is published
        weekly by the Federal Reserve System and which establishes yields on
        actively traded United States government securities adjusted to constant
        maturities, or, if such statistical release is not published at the time
        of any determination under the Indenture, then such other reasonably
        comparable index which shall be designated by the Issuer.

               (7) The Notes shall not be redeemable at the option of any Holder
        thereof, upon the occurrence of any particular circumstances or
        otherwise. The Notes will not have the benefit of any sinking fund.

               (8) The Notes shall be issuable in denominations of $1,000 and
        any integral multiple thereof.

               (9) The Trustee shall also be the Security Registrar and Paying
        Agent for the Notes.

               (10) The entire outstanding principal amount plus the Make-Whole
        Amount of the Notes shall be payable upon declaration of acceleration of
        the maturity thereof pursuant to Section 502 of the Indenture.




                                       -4-


<PAGE>   5
               (11) Payments of the principal of and interest on the Notes shall
        be made in U.S. Dollars, and the Notes shall be denominated in U.S.
        Dollars.

               (12) The Notes will be payable on the Stated Maturity Date in an
        amount equal to the principal amount thereof plus any unpaid interest
        accrued to the Stated Maturity Date.

               (13) The Holders of the Notes shall have no special rights in
        addition to those provided in the Indenture upon the occurrence of any
        particular events.

               (14) (A) There shall be no deletions from, modifications of or
        additions to the Events of Default with respect to the Notes set forth
        in the Indenture.

                      (B) There shall be the following additions to the
        covenants set forth in the Indenture with respect to the Notes, which
        shall be effective only for so long as any of the Notes are Outstanding:

                      Limitations On Incurrence of Debt. The Issuer will not,
               and will not permit any Subsidiary to, incur any Debt (as defined
               below), other than inter-company debt representing Debt to which
               the only parties are Spieker Properties, Inc., a Maryland
               corporation (the "General Partner"), the Issuer and any of their
               Subsidiaries (but only so long as such Debt is held solely by any
               of the General Partner, the Issuer and any Subsidiary) that is
               subordinate in right of payment to the Notes if, immediately
               after giving effect to the incurrence of such additional Debt,
               the aggregate principal amount of all outstanding Debt of the
               Issuer and its Subsidiaries on a consolidated basis is greater
               than 60% of the sum of (i) Total Assets (as defined below) as of
               the end of the calendar quarter covered in the Issuer's Annual
               Report on Form 10-K or Quarterly Report on Form 10-Q, as the case
               may be, most recently filed with the Trustee (or such reports of
               the General Partner if filed by the Issuer with the Trustee in
               lieu of filing its own reports) prior to the incurrence of such
               additional Debt and (ii) the increase in Total Assets from the
               end of such quarter including, without limitation, any increase
               in Total Assets resulting from the incurrence of such additional
               Debt (such increase, together with the Total Assets, is referred
               to as "Adjusted Total Assets").

                      In addition to the foregoing limitation on the incurrence
               of Debt, the Issuer will not, and will not permit any Subsidiary
               to, incur any Debt if the ratio of Consolidated Income Available
               for Debt Service to the Annual Service Charge (in each case as
               defined below) for the four consecutive fiscal quarters most
               recently ended prior to the date on which such additional Debt is
               to be incurred shall have been less than 1.5 to 1, on a pro forma
               basis after giving effect to the incurrence of such Debt and to
               the application of the proceeds therefrom, and calculated on the
               assumption that (i) such Debt and any other Debt incurred by the
               Issuer or its Subsidiaries since the first day of such
               four-quarter period and the application of




                                       -5-


<PAGE>   6
               the proceeds therefrom, including to refinance other Debt, had
               occurred at the beginning of such period, (ii) the repayment or
               retirement of any other Debt by the Issuer or its Subsidiaries
               since the first day of such four-quarter period had been
               incurred, repaid or retired at the beginning of such period
               (except that, in making such computation, the amount of Debt
               under any revolving credit facility shall be computed based upon
               the average daily balance of such Debt during such period), (iii)
               the income earned on any increase in Adjusted Total Assets since
               the end of such four-quarter period had been earned, on an
               annualized basis, during such period, and (iv) in the case of any
               acquisition or disposition by the Issuer or any Subsidiary of any
               asset or group of assets since the first day of such four-quarter
               period, including, without limitation, by merger, stock purchase
               or sale, or asset purchase or sale, such acquisition or
               disposition or any related repayment of Debt had occurred as of
               the first day of such period with the appropriate adjustments
               with respect to such acquisition or disposition being included in
               such pro forma calculation.

                      In addition to the foregoing limitations on the incurrence
               of Debt, the Issuer will not, and will not permit any Subsidiary
               to, incur any Debt secured by any mortgage, lien, charge, pledge,
               encumbrance or security interest of any kind upon any of the
               property of the Issuer or any Subsidiary ("Secured Debt"),
               whether owned at the date of the Indenture or thereafter
               acquired, if, immediately after giving effect to the incurrence
               of such additional Secured Debt, the aggregate principal amount
               of all outstanding Secured Debt is greater than 40% of Adjusted
               Total Assets.

                      For purposes of the foregoing provisions regarding the
               limitation on the incurrence of Debt, Debt shall be deemed to be
               "incurred" by the Issuer or a Subsidiary whenever the Issuer and
               its Subsidiary shall create, assume, guarantee or otherwise
               become liable in respect thereof.

                      Maintenance of Total Unencumbered Assets. The Issuer is
               required to maintain Total Unencumbered Assets of not less than
               165% of the aggregate outstanding principal amount of all
               outstanding Unsecured Debt.

                      As used herein:

                      "Annual Service Charge" as of any date means the amount
               which is expensed in any 12-month period for interest on Debt of
               the Issuer and its Subsidiaries.

                      "Consolidated Income Available For Debt Service" for any
               period means Consolidated Net Income plus amounts which have been
               deducted for (a) interest on Debt of the Issuer and its
               Subsidiaries, (b) provision for taxes of the Issuer and its
               Subsidiaries based on income, (c) amortization of Debt discount,
               (d) provisions




                                       -6-


<PAGE>   7
               for gains and losses on properties, (e) depreciation and
               amortization, (f) the effect of any noncash charge resulting from
               a change in accounting principles in determining Consolidated Net
               Income for such period and (g) amortization of deferred charges.

                      "Consolidated Net Income" for any period means the amount
               of consolidated net income (or loss) of the Issuer and its
               Subsidiaries for such period determined on a consolidated basis
               in accordance with generally accepted accounting principles.

                      "Debt" of the Issuer or any Subsidiary means any
               indebtedness of the Issuer or such Subsidiary, as applicable,
               whether or not contingent, in respect of (i) borrowed money
               evidenced by bonds, notes, debentures or similar instruments,
               (ii) indebtedness secured by any mortgage, pledge, lien, charge,
               encumbrance or any security interest existing on property owned
               by the Issuer or such Subsidiary, (iii) the reimbursement
               obligations, contingent or otherwise, in connection with any
               letters of credit actually issued or amounts representing the
               balance that constitutes an accrued expense or trade payable or
               (iv) any lease of property by the Issuer or such Subsidiary as
               lessee which is reflected in the Issuer's consolidated balance
               sheet as a capitalized lease in accordance with generally
               accepted accounting principles, in the case of items of
               indebtedness under (i) through (iii) above to the extent that any
               such items (other than letters of credit) would appear as a
               liability on the Issuer's consolidated balance sheet in
               accordance with generally accepted accounting principles, and
               also includes, to the extent not otherwise included, any
               obligation by the Issuer or such Subsidiary to be liable for, or
               to pay, as obligor, guarantor or otherwise (other than for

               indebtedness of another person (other than the Issuer or any
               Subsidiary).
