                                     PART I

This Annual Report contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. The Operating Partnership's actual
results could differ materially from those set forth in the forward-looking
statements as a result of various factors, including general real estate
investment risks, competition, risks associated with acquisition and development
activities and financing, environmental matters, general uninsured losses and
seismic activity.

OVERVIEW

Spieker Properties, L.P. is one of the largest owners and operators of office
and industrial properties located in selected West Coast markets. These markets
are primarily located in greater Seattle, Washington; greater Portland, Oregon;
Northern California and Southern California. The Operating Partnership is a
self-managed and self-administrated real estate investment trust or REIT. The
Operating Partnership was formed to continue and expand the real estate
activities, including the acquisition, development, management and leasing of
the properties of its predecessor firm, Spieker Partners, which launched in
1970. With the contributions of the properties from Spieker Partners the Company
commenced operations with the completion of its initial public offering in
November 1993. Substantially all of the business activities of Spieker
Properties, Inc. are conducted through Spieker Properties, L.P. in which the
Company owned an approximate 88.0% general partnership interest at December 31,
1999. Unless the context otherwise requires, Spieker Properties, Inc., is
referred to as the Company, Spieker Properties, L.P., is referred to as the
Operating Partnership and they are collectively referred to as the Company.

As of December 31, 1999, the Operating Partnership owned 40.7 million square
feet of commercial real estate, which was 96.3% occupied at year-end. The
portfolio mix consists of 22.0 million square feet of office property and 18.7
million square feet of industrial property. The Operating Partnership acquired
five office properties totaling 807,037 square feet and completed eleven
development properties totaling 1.9 million square feet during the year. In the
development pipeline at year-end, the Operating Partnership had fifteen offices
and three industrial properties totaling 2.7 million square feet, which were
76.1% pre-leased.

BUSINESS STRATEGY

The Operating Partnership's principal objective is to achieve sustainable,
long-term growth in funds from operations per share through maximizing the
return on each dollar of capital invested and building value in the portfolio by
the following focused and consistent business strategies.

Quality Office and Industrial Properties

With approximately 30 years of experience in owning and operating commercial
properties, the Operating Partnership's management team possesses the in-depth
knowledge necessary to assess the attributes that determine a property's
long-term viability. The Operating Partnership owns and invests in high quality
office and industrial properties that possess attributes that are competitive in
the marketplace in both the short and long-term.

The Operating Partnership focuses on differentiating its properties from those
of nearby competitors, so as to maximize their attractiveness to potential
customers. Important differentiating characteristics in office buildings include
efficient suite layouts, ample glass line per square foot of office space, well
designed and maintained common areas, elevators, and convenient parking. Further
differentiation is achieved through amenities and services provided such as
on-site management, conference rooms and health clubs. Distribution properties
are designed with ample clear heights, multiple dock facilities, appropriate
truck staging and high-capacity sprinkler systems. In its light industrial and
R&D properties the Operating Partnership also uses landscaping and exterior
glass walls to increase attractiveness.

Flexible, Multi-Tenant Properties

The Operating Partnership focuses on properties which will appeal to a broad
range of potential tenants. These properties are easily divisible and can
accommodate new tenants of various sizes. This flexibility also enables the
Operating Partnership to meet the needs of existing tenants by accommodating
their expansion and contraction needs. In addition to flexibility, the Operating
Partnership also focuses on multi-tenant usage of its properties. The Operating
Partnership's experience is that multi-tenant properties help maintain high
occupancy rates, particularly when market conditions are less favorable, and
help control the cost of re-tenanting space.

Invest in Growing Regions

The Operating Partnership seeks to invest in regions with diverse and active
economies that possess strong prospects for sustained long-term economic growth.
The Operating Partnership believes that California and the Pacific Northwest
possess attributes - high concentration of technology industries, growing
populations with a well-educated employee base, ability to attract new capital,
excellent universities, quality of life and well-developed infrastructures -
that will contribute to continued economic growth. Within these growing regions
the Operating Partnership focuses its activities in the major metropolitan areas
of Seattle, Portland, San Francisco, San Jose, Sacramento, Los Angeles County,
Orange County and San Diego, which have proven to be desired locations for a
large number of businesses.

Submarket Concentration

In the specific local submarkets in which it operates, the Operating Partnership
generally seeks to own a number of properties and to be one of the more
significant commercial landlords in that submarket. The Operating Partnership
believes that it has achieved significant market penetration within a number of
submarkets in which it operates. By achieving concentrated market positions, the
Operating Partnership can offer prospective tenants a variety of property
options and can accommodate the growth of existing tenants. This strategy also
gives it a measure of control over the rental rates achieved and capital
expenditures incurred in leasing space.

Superior Level of Service

The Operating Partnership believes in providing a superior level of service to
its customers which will allow them to focus on their business rather than on
property issues. To achieve this level of service, the Operating Partnership's
office property managers and customer service personnel are located on-site,
providing tenants with convenient direct access to a team which can respond
quickly to the customer's needs. These on-site teams enable the properties to be
well maintained and convey a sense of quality, order and security. This superior
level of service and ultimate customer satisfaction translates to lower customer
turnover, higher occupancy levels and higher rental rates.

Operating Efficiencies

The Operating Partnership recognizes the importance of creating operating
efficiencies that add additional value to the portfolio and to the shareholder
by utilizing opportunities created by its submarket concentrations as well as
leveraging its relative size and scale.

By integrating properties in its submarkets, the Operating Partnership has been
able to pool its resources and maximize economies of scale to allow its key
operating personnel to concentrate their expertise on those specific markets and
their particular local conditions. Minimizing project personnel requirements
with the centralization of these properties has created additional cost savings.

During 1999, the Operating Partnership utilized its relative size and purchasing
ability to put in place several vendor related efficiency programs. These
programs were designed to ensure consistency in the quality products purchased
and services provided, to create operational cost savings, and to allow for
tracking purchasing trends for future purchasing consolidation opportunities.
These programs significantly reduce the number of vendors with which the
Operating Partnership now does business and puts cost and time saving
efficiencies in place that the project teams can utilize in managing their
projects. Additional efficiencies have been created in the Operating
Partnership's accounting processes by limiting the number of vendor's invoices
that must be managed.

Rent Growth

The strength in the West Coast economy continued to fuel the demand for quality
commercial space in the Operating Partnership's markets. Healthy demand pared
with modest levels of new supply has translated to an upward pressure on market
rents. These increases provided the Operating Partnership with the opportunity
to generate positive rent growth during the year. This rent growth, measured as
the difference between effective (average) rents on new and renewed leases as
compared to the expiring coupon rent on those same spaces, was 36.5% for 1999.



                                       4
<PAGE>   5

The Operating Partnership estimates that the embedded rent growth, as measured
is the difference between existing in-place rents and current market rents, in
the Operating Partnership's operating portfolio is approximately $1.60 per share
at year-end. As of December 31, 1999, 74.3% of all leases in-place during the
next four years are set to expire. The Operating Partnership expects to
capitalize on embedded rent growth as these leases and future leases, expire and
as the spaces are either renewed or re-leased. There can be no assurances,
however that market rents will not erode in the future or that the Operating
Partnership will realize all of the embedded rent growth.

Investment Activity

The Operating Partnership strategically invests in real estate either through
the acquisition of existing properties or through the development of new
properties. When evaluating potential investments, in addition to both the
physical and location attributes, the Operating Partnership also considers short
and long-term returns on capital, total cost compared to replacement cost, the
level of in-place rents compared to current market rents and tenant mix. In
assessing the viability of a potential development, the Operating Partnership
also considers market demand and competitive supply.

Acquisitions

During 1999, the Operating Partnership acquired five office properties. These
acquisitions were primarily funded by the redeployment of capital from the
disposition of non-strategic assets (see Note 3 to the consolidated financial
statements for further discussion of the Operating Partnership's asset
dispositions).

Developments in Process

At the end of 1999, the Operating Partnership had fifteen office properties and
three industrial properties under development that will add approximately 2.7
million square feet to the Operating Partnership's operating portfolio. Of the
eight development projects added to the pipeline in 1999, five were 100%
pre-leased. The nine projects that were a part of the 1998 pipeline and are
still a part of the 1999 pipeline, are approximately 73.1% leased. It can be
expected that these projects, totaling 1.3 million square feet, will stabilize
and will be added to the Operating Partnership's operating portfolio in 2000.

Employees

As of December 31, 1999, the Operating Partnership had 568 employees.

Fully-Integrated Real Estate Management Capabilities

The Operating Partnership has had, and will continue to have, a philosophy of
maintaining in-house resources to add value to its properties through the entire
cycle of acquisition, development and ownership. The Operating Partnership
believes its key in-house resource is its fully integrated sub-regional teams.
These teams led by an officer with extensive real estate experience, have the
collective ability to design, construct, market, lease and manage the Operating
Partnership's properties. This eliminates the need for the Operating Partnership
to use third-party managers and limits the utilization of outside parties to
list its properties. The Operating Partnership believes this integrated team
approach gives it a significant advantage in depth of experience and a detailed
knowledge of its markets.

Training and Retention

The Operating Partnership's training and retention of a talented group of
officers and employees has been an important factor in its success. The
Operating Partnership expends significant efforts in the training of new
employees in fundamental real estate skills as well as in the continuing
education of existing employees. The Operating Partnership's officers, including
the executive officers, are also involved in the education program, which
reinforces the program's importance to the Operating Partnership and its
personnel.

In addition to training, the Operating Partnership also provides its employees
with profit sharing, 401(k) contribution matches and competitive health plans.
The Operating Partnership also understands the importance of having up to date
technology available for its employees to perform their jobs efficiently and
effectively. The Operating Partnership provides employees with leading edge
computer resources, including modern hardware/software, high speed connection to
corporate data sources, internet connections, and internally designed interfaces
to aid the employees in timely decision making.

Compensation

The Operating Partnership's officer compensation program includes cash bonuses,
stock options, and restricted stock payments tied largely to growth in net
operating income from existing properties under their management, as well as
increased funds from operations from new acquisitions and developments in their
regions and other contributions. Non-officer compensation includes subjective
bonuses based upon employee performance factors including tenant satisfaction
and leasing and releasing success. The Operating Partnership also grants stock
options to all full-time employees upon the completion of one year of service
with the Operating Partnership.

Accountability

The Operating Partnership has a philosophy of holding one senior officer or a
small group of senior officers accountable, under the supervision and direction
of the Operating Partnership's executive officers, for all phases of a
property's development, from purchase, design and construction, through
budgeting, leasing and ongoing management. The Operating Partnership believes
that this approach increases the likelihood of a project's success because of
the senior officer's accountability, continuity of involvement in the project
and resulting detailed knowledge of the property and its tenants, particularly
as compared to a compartmentalized approach to the real estate business where
individuals are responsible for only certain limited areas of a project.

Leasing Activity/Releasing Costs

The Operating Partnership continues to aggressively manage the cost of leasing
commissions and tenant improvements, collectively referred to as capital
expenditures associated with the renewal and releasing of space. The relative
strength of the local real estate market, the type of property being leased, the
length of the leases signed and the total value of the leases signed impact the
amount of capital expenditures spent on leasing second generation space. Average
capital expenditures per square foot of space leased has shown moderate growth
over time. These increases, specifically related to higher labor, material
costs, and higher leasing commissions are directly correlated to a shift in the
Operating Partnership's portfolio towards office properties, rapidly increasing
market rents, which result in higher leasing commissions, and longer average
lease terms. The following table highlights 1999 leasing activity and releasing
costs by property type.

Tenant Profiles

The Operating Partnership has over 3,500 tenants, with the average tenant
occupying approximately 11,421 square feet and paying an annual net rent of
approximately $132,453. The tenant base is extremely diversified, as
demonstrated below, based on the business sectors in which they operate. The
Operating Partnership's largest tenant, Xerox, represents approximately 1.1% of
the Operating Partnership's 1999 net rental income. A sample of the Company's
top fifty tenants includes: Applied Materials, Sony Computer Entertainment,
Microsoft, Countrywide Credit, Nextel Communications, SAP America and Gilead
Sciences. The top fifty tenants represent less than 21.7% of the Operating
Partnership's 1999 net rental income.

Other Business Opportunities

Although the Operating Partnership's primary business objective is to own,
operate, acquire and develop property, it will continue to pursue other business
opportunities which will maximize shareholder value. These opportunities may be
available as a result of our building and tenant base and the depth of and
experience of the Operating Partnership's employees.

As an example, after surveying the growing telecommunications needs of our
tenants, the Operating Partnership, together with eight other real estate firms
and leading venture capital firm, Kleiner Perkins Caulfied & Byers,


                                       12
<PAGE>   13
formed a national telecommunications company, Broadband Office, Inc. Broadband
Office will provide voice and data communications services to both the Operating
Partnership's tenants and to other tenants in their respective office buildings
across the country. By giving the tenants the ability to have direct, single
point access to advanced telecommunication services, the Operating Partnership
will not only generate greater tenant satisfaction, obtain higher rents and a
higher rate of renewal, but the Operating Partnership will generate an
additional source of revenue.

Competition

The Operating Partnership competes with other real estate firms in its markets
in attracting tenants, primarily on the basis of location, rental rates,
services provided and the design and condition of the improvements. These
competitors include domestic and foreign financial institutions, other REITs,
life insurance companies, pension funds, trust funds, partnerships and
individual investors.

The number of competitive commercial properties in a particular area could have
a material effect on the Operating Partnership's ability to lease space in its
properties or at newly developed or acquired properties and on the rents
charged. Since the Operating Partnership is also acquiring and actively
developing properties in its markets it also faces competition in its efforts to
acquire or develop desirable real estate.

CAPITAL STRUCTURE AND WORKING CAPITAL

The Operating Partnership's principal sources of funding for its ongoing
operations, which include the leasing and build-out of existing space as well as
the acquisition, development, expansion and renovation of additional properties
and debt maturities, are cash flows provided by operations, unsecured short-term
borrowings, public and privately placed equity financing, public unsecured debt
financing, the issuance of partnership units in the Operating Partnership,
proceeds from the disposition of non-strategic assets and the assumption of
secured debt on properties acquired. The Operating Partnership believes that its
ability to access a variety of capital sources enables it to reduce its overall
cost of capital and maintain a prudent capital structure. The Operating
Partnership's fixed rate debt has interest rates for the unsecured investment
grade notes between 6.65% and 8.00% and maturity dates ranging from 2000 to
2027.

OTHER DISCLOSURES

Environmental Matters

Compliance with laws and regulations relating to the protection of the
environment, including those regarding the discharge of materials into the
environment, has not had any material effect upon the financial condition or
results of operations of the Operating Partnership.

The 97 properties owned by the Operating Partnership at December 31, 1993, were
each subject to a Phase I environmental audit or update during the twelve-month
period ended during December 31, 1993. Certain of these properties were subject
to Phase II environmental investigations and all buildings on such properties
constructed prior to 1985 have been subject to asbestos detection
investigations. In addition, for each of the properties acquired subsequent to
December 31, 1993, and for each parcel of land purchased for development, a
Phase I environmental audit or update was completed as part of the acquisition
due diligence process. These investigations have not revealed any environmental
condition that the Operating Partnership believes would have a material effect
on its business, assets or results of operations.

Site assessments have revealed soil and ground water contamination at the
Stender Way II property in Santa Clara, California. A third party is primarily
bearing the costs relating to this environmental condition and the Operating
Partnership believes that its exposure, if any, is not material. Additionally,
three properties located in Stanford Research Park in Palo Alto, California are
subject to varying degrees of known environmental contamination. The remediation
costs associated with this contamination have also been, and are expected to
continue to be, borne by other parties. Furthermore, the Operating Partnership
has entered into indemnification agreements whereby the Operating Partnership
has been, and is to be, indemnified for liabilities arising from clean-up costs
relating to these three properties.

Environmental contamination has been found to have originated at Walsh at
Lafayette, an industrial development project site in Santa Clara, California
that was acquired by the Operating Partnership in 1995. The Company has since
developed a 320,505 square feet industrial building on this site. The relevant
government agency has identified a third party as responsible for remediation,
and the remediation process is continuing. The Operating Partnership is
being indemnified for environmental contamination on the Walsh at Lafayette
property by a third party that was the former owner of the property.

Site assessments have revealed that soil and groundwater at the Operating
Partnership's Montgomery Ward property in Pleasant Hill, California, have been
contaminated with volatile organic compounds. The likely sources of this
contamination are on-site underground storage tanks and a potential off-site
contamination source. To date, no government agency has issued any directives
requiring that a remediation plan be filed or the contamination be cleaned up.
The Spieker partnership that transferred this property, referred to as the
transferor, to the Operating Partnership previously filed a lawsuit against the
seller to enforce an indemnity agreement and against certain other potentially
responsible parties to have those parties bear any clean-up costs. Settlement
has been reached with certain of the defendants in the lawsuit, resulting in
cash payments to the transferor. A trial involving the remaining defendants
ended without any additional cash awards being made. Due to the nature of this
environmental condition and the Operating Partnership's expectation that other
parties will be primarily responsible for the clean-up costs, the Operating
Partnership believes that its exposure, if any, for clean-up costs would not
have a material adverse effect on the Operating Partnership's financial
condition, results of operations or liquidity.

                                       14
<PAGE>   15

Site assessments have revealed soil and groundwater contamination at the Arden
Square property in Sacramento, California, and the Woodside Central property in
Woodside, California, which have since been sold to Pacific Retail Trust. The
Operating Partnership agreed to indemnify the buyer for the contamination.
However, the Operating Partnership believes that the liabilities and clean-up
costs associated with this contamination are covered by the Operating
Partnership's pollution insurance policy, except to the extent of the deductible
under such policy.

Property owned by GAF Corporation and/or Mattel, Inc. in the vicinity of the
Nimbus Corporate Center property in Beaverton, Oregon was discovered to have
very high levels of soil and groundwater contamination. Monitoring is currently
being conducted to determine the extent, if any, that such contamination may
have affected the Nimbus Corporate Center property and whether any remedial
action will be required. The Operating Partnership believes the GAF, Mattel
and/or other third parties will bear the liabilities and remediation costs
associated with this contamination, and that, if any event, any exposure the
Operating Partnership might have, would be covered by the Operating
Partnership's pollution insurance policy, except to the extent of the deductible
under such policy.

Site assessments have revealed soil and groundwater contamination at the
Georgetown Center property in Seattle, Washington, and the City Commerce Park
property in Seattle, Washington, which properties have since been sold to
CalWest Industrial Properties, LLC, a California limited liability company. The
Operating Partnership agreed to indemnify the buyer for the contamination.
Monitoring will be conducted to determine the extent, if any, that such
contamination may have affected the Georgetown Center property and the City
Commerce Park property, and whether any remedial action will be required.

Although the environmental investigations conducted to date have not revealed
any environmental liability that the Operating Partnership believes would have a
material adverse effect on the Operating Partnership's business, assets or
results of operations, and the Operating Partnership is not aware of any such
liability, it is possible that these investigations did not reveal all
environmental liabilities or that there are material environmental liabilities
of which the Operating Partnership is unaware. No assurances can be given that
(1) future laws, ordinances, or regulations will not impose any material
environmental liability, or (2) the current environmental condition of the
Properties has not been, or will not be affected by tenants and occupants of the
Properties, by the condition of properties in the vicinity of the Properties, or
by third parties unrelated to the Operating Partnership.

(2)  Refer to "Funds of Operations" in Item-7 Management's Discussion and
     Analysis of Financial Condition and Results of Operations for discussion
     and definition of the Operating Partnership's Funds from Operations. In
     February 1995; the National Association of Real Estate Investment Trusts
     ("NAREIT") established its definition of Funds from Operations and
     requested that REITs adopt this new definition beginning in 1996. The new
     definition provided that the amortization of debt discount and deferred
     financing costs is no longer to be added back to net income to calculate
     Funds from Operations. In 1996, the Operating Partnership substantially
     implemented the new NAREIT definition for calculating Funds from
     Operations. The amount presented above for the year ended December 31,
     1995, was $70,790 based on the old NAREIT definition.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Statements contained in this Item 7, "Management's Discussion and Analysis of
Financial Condition and Results of Operations," and elsewhere in this Form
10-K, which are not historical facts, may be forward-looking statements. These
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 Operating
Partnership'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 Operating Partnership 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

Overview

In 1999, the Operating Partnership focused on maximizing the value of its real
estate portfolio by increasing the cash flow from its properties, by increasing
effective rents and maintaining high occupancy levels, as well as completing
strategic value added asset acquisition, development and disposition
transactions. The Operating Partnership also continued to focus on maintaining a
capital structure that allows the Operating Partnership to execute its business
strategy.

The Operating Partnership continued to experience solid rent growth in its
portfolio of properties. For the year ended December 31, 1999, net effective
rents on average were 36.5% higher than the expiring coupon rent on the 8.0
million square feet of second generation space renewed or re-leased. For the
year ended December 31, 1998, rollover rents grew by 37.4% on approximately 8.3
million square feet of second generation space.

During 1999, the availability of assets that would meet the Operating
Partnership's stringent acquisition requirements were limited. Accordingly, the
Operating Partnership purchased significantly fewer assets in 1999 than in 1998.
Of the 807,037 square feet of office property added to its portfolio during 1999
(the "1999 Acquisitions"), two office properties were added in the Pacific
Northwest totaling 554,588 square feet for a total investment of $96.4 million
and three were added in Southern California totaling 252,449 square feet for a
total investment of $37.9 million.

The Operating Partnership continues to review its portfolio to identify assets
whose value has been fully realized. During 1999, the Operating Partnership
identified approximately 2.9 million square feet of property that was
subsequently disposed of and the proceeds were either traded into new properties
or used to fund the Operating Partnership's developments in process.

The Operating Partnership continued to increase its level of development
activity during 1999. During 1999, the Operating Partnership added eight
projects totaling 1.3 million square feet to its development pipeline for a
total investment of approximately $237.7 million while it completed eleven
properties, adding 1.9 million square feet to its stabilized portfolio for a
total investment of $166.9 million. At December 31, 1999 the Operating
Partnership had developments and redevelopments in process of approximately 2.7
million square feet of office and industrial properties for a total investment
of $473.8 million. Further breakdown of the Operating Partnership's developments
and redevelopments in process can be found in Part I of this Form 10-K. The
developments completed during 1999 and the developments in process at December
31, 1999, are collectively referred to as the "Developments". A few of the
developments in process, though not yet completed, were partially leased and
occupied during 1999 and, accordingly, revenue and expense amounts for these
developments are included in the Operating Partnership's operating results for
the year ended December 31, 1999.

The Operating Partnership continued to maintain a strong balance sheet. In 1999,
the Operating Partnership issued $400.0 million of investment grade rated
unsecured notes in two tranches with maturities ranging from four to ten years.

                         ======      ======      ======        ======
</TABLE>

Rental revenues for 1999 increased by $95.4 million. $32.5 million, or 34.1%, of
the rental revenue increase is due to revenues generated by the "1998 Core
Portfolio", defined as properties owned at January 1, 1998 and still owned at
December 31, 1999. Properties acquired during 1998 contributed $30.1 million, or
31.6%, to the rental revenue increase for the year. During 1998, the Operating
Partnership invested $884.8 million in acquiring properties totaling 6.3 million
square feet (the "1998 Acquisitions"). The properties were acquired at various
dates throughout the year and as such the Operating Partnership recognized a
full year's results in 1999 as compared to a partial year's results in the year
of acquisition. Increases in the 1998 Core Portfolio rental revenues and to some
extent the 1998 Acquisitions rental revenues during 1999 were attributable to
higher rollover rental rates realized on the renewal and releasing of second
generation space and built in rent increases. During 1999, the Operating
Partnership completed 1,326 lease transactions for the renewal and re-lease of
8.0 million square feet of second generation space. Rollover effective rent
growth on these leases was on average, 36.5% higher than the previous rents
received on those same spaces.

The Developments contributed $27.9 million, or 29.2%, to the rental revenue
increases for 1999. The increase in income is due to the increases in occupancy
on the developments either completed or still in the development pipeline. The
Developments include both properties completed and added to the Operating
Partnership's portfolio of stabilized properties, as well as properties
currently under development. The Operating Partnership considers properties
"stabilized" at the earlier of eighteen months after shell completion or when a
95.0% occupancy rate has been reached.

The 1999 Acquisitions contributed $8.1 million of the rental revenues for 1999.
For the year, the Operating Partnership acquired five office properties totaling
807,037 square feet for a total investment of $134.3 million.

Consistent with the Operating Partnership's strategy to maintain the highest
quality portfolio, the Operating Partnership sold properties in 1999 that did
not meet its stringent investment criteria. During 1999, the Operating
Partnership disposed of fifteen properties and two land parcels ("1999
Dispositions"), for a total sales price of $184.8 million recognizing a book
gain of $48.6. Increases in rental revenues for the Operating Partnership were
partially offset by a decrease of $3.2 million attributable to the 1999
Dispositions (see Note 3 to the consolidated financial statements). The gains
generated from these sales were re-deployed into the purchase of the 1999
Acquisitions into assets purchased subsequent to December 31, 1999 and to fund
the development pipeline. The Operating Partnership also recognized income from
the sale of a mortgage and a gain on condemnation of a land parcel of $20.2
million.

Interest and Other Income      $ 6.0      $18.7      $(12.7)     (67.9)%

Interest and other income decreased due to the reduction in interest income from
mortgage loans made to SNI in relation to SNI's 1997 acquisition of non-core
assets. The majority of these assets were disposed of during 1998. Additionally,
interest earned decreased slightly due to lower cash balances year over year and
from the reduction of mortgage interest income due to the payoff on a mortgage
held by the Operating Partnership, which was

repaid by the borrower. Average cash balances for the year ended December 31,

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 Operating Partnership's portfolio of
properties. The increased number of employees, as well as higher compensation
costs were the principal drivers of the increase in rental expenses. The
increases experienced are consistent with the increase in rental revenue.


Rental revenues net of property operating expenses, referred to as "net
operating income," is presented in the following tables:

operating income was generated by office properties as compared with 69.1% for
1998 (for further breakdown of rental revenue and net operating income at

</TABLE>


Interest expense increased due to a higher total average outstanding debt
balance in 1999. This increase is the net effect of additions to interest
expense from additional note offerings which occurred during 1999, offset by
lower balances outstanding under the Facility, the payoff of the Bank Facility
combined with an increase in interest capitalized in relation to the
Developments that the Operating Partnership had in process during the year. The
average outstanding debt was $2.0 billion in 1999 and $1.8 billion in 1998.

Depreciation and amortization expenses increased by $16.9 million for 1999 as
compared with 1998, due primarily to the 1999 and 1998 Acquisitions and the
Developments.

General and administrative expenses increased by $4.2 million for 1999 as
compared with 1998, primarily as a result of the increased number of employees,
wage pressures experienced on the west coast. However, 1999 general and
administrative expenses were consistent with 1998 levels on a percentage of
revenue basis.

During 1999, the Operating Partnership recorded gains on disposition of real
estate of $58.5 million. The gain includes $5.2 million of gain recognized on a
mortgage held by the Operating Partnership, which was repaid by the borrower, a
$4.7 million condemnation gain and $48.6 million on the disposition of fifteen
properties and two land parcels.

</TABLE>

The increase in income from operations before disposition of real estate and
minority interests of $31.6 million for the year ended December 31, 1999 is
principally due to rent increases in the 1998 Core Portfolio and the 1998
Acquisitions, the 1999 Acquisitions, and the Developments coming on line during
the year.

</TABLE>

Rental revenues for 1998 increased by $220.8 million. Of this increase, $117.6
million was generated by the properties acquired during 1997 (the "1997
Acquisitions"), for which the Operating Partnership recognized a full year's
results in 1998 as compared to a partial year's results in the year of
acquisition. $86.5 million was generated by the 1998 Acquisitions, which were
acquired on various dates throughout 1998. $17.6 million is attributable to the
Developments and $13.7 million is attributable to the 1997 Core Portfolio. The
"1997 Core Portfolio" is defined as properties owned at January 1, 1997 and
still owned at December 31, 1998. Increases in the 1997 Core Portfolio can be
attributed to higher rents on rollovers, contractual rent increases and
increased occupancy. The increases in rental revenue are partially offset by a
decrease of $14.6 million attributable to the disposition of properties which
were owned by the Operating Partnership during the year ended December 31, 1997
(the "1998 Dispositions").

</TABLE>


The increase in interest and other income is due to interest income from
mortgage loans made to SNI in relation to SNI's acquisition of non-core assets.
These assets have subsequently been sold. This increase is slightly offset by a
decrease in interest earned on cash balances. Average cash balances for the year
ended December 31, 1998 were $33.9 million compared to $56.4 million in 1997.

The overall increase in property operating expenses is primarily a result of the
growth in the total square footage of the Operating Partnership's portfolio of
properties. The increase in property operating expenses as a percentage of
rental revenues is attributable to the increased percentage of office properties
in the Operating Partnership's portfolio. For the year ended December 31, 1998,
69.1% of the Operating Partnership's net operating income (rental revenues less
property operating expenses) was generated by office properties as compared with
60.1% for 1997.

</TABLE>


The increase in interest expense of $54.0 million is due to increases in the
total average outstanding debt balances. The average outstanding debt was $1.8
billion for 1998 and $936.0 million in 1997 and is consistent with the increase
in the size of the Operating Partnership's portfolio of properties.

Depreciation and amortization expenses increased by $41.7 million for 1998 as
compared with 1997, due to the 1998 and 1997 Acquisitions and the completed
Developments.

General and administrative expenses increased by $4.5 million for 1998 as
compared with 1997, primarily as a result of the increased number of employees.
On a percentage basis, general and administrative expenses were 3.6% of rental
revenues for 1998, as compared with 4.6% for 1997 reflecting economies of scale
associated with the growth of the Operating Partnership.

During 1998, the Operating Partnership disposed of one retail property, two
office properties, four industrial properties and two land parcels resulting in
a gain of $20.1 million.

increased by $53.8 million or 48.9%. The increase in income from operations
before disposition of real estate and minority interests is principally due to
the 1998 and 1997 Acquisitions.

</TABLE>

The increase in cash provided by operating activities is primarily due to the
net income resulting from the 1998 and 1999 Acquisitions, the Developments and
the 1998 Core Portfolio partially offset by a decrease in accounts payable. The
decrease in accounts payable is due to timing differences in the payment of
accounts payable balances at the end of each comparable period. Cash used for
investing activities was significantly lower due to the decrease in the number
of acquisitions completed. Cash used for/provided by financing activities
decreased by $572.1 million for 1999, as compared to the same period in 1998.
The change is consistent with the Operating Partnership's decreased investment
activity and the Operating Partnership's ability to fund part of its investment
activity with the proceeds from asset dispositions. During 1999, cash provided
by financing activities consisted primarily of $400.0 million in gross proceeds
from the issuance of unsecured notes (see below). The increases were offset by
the payment of $200.0 million on the Company's short-term bank facility (the
"Bank Facility"), net payments of $37.0 million on the Facility, re-payment of
$34.0 million in mortgage loans and principal payments of $8.9 million on
mortgage loans. Additionally, re-payments of dividends and distributions
increased by $23.0 million from $195.9 million in 1998 to $218.9 million for
1999. This increase is due to the greater number of common and preferred shares
outstanding and the 7.0% increase in the common share and operating partnership
unit distribution rate of $2.44 per share and unit for 1999 from $2.28 per share
in 1998.

The principal sources of funding for acquisitions, development, expansion and
renovation of properties and debt maturities are unsecured short-term
borrowings, public and privately placed equity financing, public unsecured debt
financing, the issuance of partnership units in the Operating Partnership,
proceeds from dispositions, the assumption of secured debt on properties
acquired and cash flow provided by operations. The Operating Partnership
believes that its liquidity and its ability to access capital and proceeds from
disposition of non-strategic assets are adequate to continue to meet liquidity
requirements for the foreseeable future.

At December 31, 1999, 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 Bank Facility provide sufficient
sources of liquidity to fund capital expenditure costs associated with the
renewal or re-leasing of space.

In February, March and April 1998, the Company placed 710,832 shares, 608,828
shares and 1,166,144 shares, respectively, of Common Stock at prices of $42.25,
$41.06 and $39.88 in Unit Investment Trusts along with other publicly traded
REITs. Additionally, in July 1998, there was a private offering for 173,664
shares at $38.39. The net proceeds of these transactions of $96.3 million were
used to pay down borrowings on the line of credit and to fund the ongoing
acquisition and development of properties.

In April 1998, the Company sold 1,500,000 Series D Cumulative Redeemable
Preferred Units (the "Series D Preferred Units") to an institutional investor
for $50.00 per unit. Dividends are payable at an annual rate of 7.6875%. The
Series D Preferred Units may be called by the Company at par on or after April
20, 2003, and have no stated maturity or mandatory redemption. The Series D
Preferred Units are exchangeable for the Series D Cumulative Redeemable
Preferred Stock of the Operating Partnership on or after April 20, 2008. The net
proceeds of $73.1 million for the Series D Preferred Units were used to pay down
the line of credit and to fund future growth of the Company.

In June 1998, the Company sold 4,000,000 shares of Series E Cumulative
Redeemable Preferred Stock for $25.00 per share. These shares are redeemable at
the option of the Operating Partnership. Dividends are payable at an annual rate
of 8.00% of the redeemable liquidation preference of $100.0 million. Net
proceeds of $96.4 million were used principally to repay borrowings on the
unsecured line of credit and to fund the ongoing acquisition and development of
property.

In 1998, the Operating Partnership issued $301.5 million of investment grade
rated unsecured notes in four tranches as follows: $150.0 million of 6.75% notes
due January 15, 2008; $125.0 million of 6.875% notes due February 1, 2005; $1.5
million of 7.0% notes due February 2, 2007 and $25.0 million of 6.880% notes due
April 30, 2007. Net proceeds of $299.1 million were used to repay borrowings on
the unsecured line of credit and to fund the acquisition and development of
properties.

In May 1999, the Operating Partnership issued $400.0 million of investment grade
rated unsecured notes in two tranches as follows: $200.0 million of 6.8% notes
due May 1, 2004 priced to yield 6.83% and $200.0 million of 7.25% notes due May
1, 2009 priced to yield 7.27%. The Company used the net proceeds of
approximately $397.0 million from this offering to reduce amounts outstanding
under the Facility and the Bank Facility.

In conjunction with the issuance of the May 1999 Notes, the Company hedged its
exposure to pricing benchmarks so that the net cost to the Operating Partnership
was 6.74% for the 2004 notes and 7.18% for the 2009 notes. The Company was
released from any further obligations under the hedge transaction upon issuance
of the May 1999 Notes.

As of December 31, 1999, the Operating Partnership had $1.8 billion of
investment grade rated unsecured debt securities outstanding. The debt
securities have interest rates that vary from 6.65% to 8.0% and maturity dates
that range from 2000 to 2027.

The Operating Partnership has a $250.0 million Unsecured Line of Credit Facility
with interest at London Interbank Offering Rate ("LIBOR") plus .80%. This
Facility matures in August 2001, and has a competitive bid option that allows
the Operating Partnership to request bids from the lenders for advances up to
$150.0 million. At December 31, 1999, the Operating Partnership had $63.0
million outstanding under the Facility. The Facility is subject to financial
covenants concerning leverage, interest coverage and certain other ratios. The
Operating Partnership is currently in compliance with all of the covenants in
the Facility concerning its indebtedness. During the quarter ended June 30, 1999
the Operating Partnership paid down the Bank Facility which had an outstanding
balance of $200.0 million. The Bank Facility carried interest at LIBOR plus
0.65% and was to mature in November 1999.

In addition to the unsecured debt securities and the Facility, the Operating
Partnership has $97.3 million of secured indebtedness (the "Mortgages") at
December 31, 1999. The Mortgages have interest rates varying from 7.00% to 9.88%
and maturity dates from 2001 to 2013. 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 Operating Partnership also has $10.2
million of assessment bonds outstanding as of December 31, 1999.

The Company has the capacity pursuant to shelf registration statements to issue
up to approximately $663.8 million in equity securities and the Operating
Partnership has the capacity to issue up to $413.5 million in debt securities.

FUNDS FROM OPERATIONS

The Operating Partnership 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, or GAAP,
and Funds from Operations should not be considered as an alternative to net
income as an indicator of the Operating Partnership's operating performance or
as an alternative to cash flows as a measure of liquidity. Funds from Operations
do not measure whether cash flow is sufficient to fund all of the Operating
Partnership's cash needs including principal amortization, capital improvements,
and distributions to stockholders. Funds from Operations do not represent cash
flows from operating, investing, or financing activities as defined by GAAP.
Further, Funds from Operations, as disclosed by other REIT's may not be
comparable to the Operating Partnership's calculation of Funds from Operations,
as described below.

Pursuant to the National Association of Real Estate Investment Trusts, or
NAREIT, revised definition of Funds from Operations, the Operating Partnership
calculates 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 Operating Partnership 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


                                       25
<PAGE>   26

Operating Partnership eliminates the effect of straight-lined rents, as defined
under GAAP, in its FFO calculation, 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
outstanding, assuming the conversion of all shares of Series A Preferred Stock,
and all Operating Partnership units outstanding into shares of Common Stock and
including the dilutive effect of stock option equivalents computed using the
treasury stock method.

</TABLE>


The variable rate debt represents 3.2% and the fixed rate debt represents 96.8%
of all the debt outstanding. The carrying amount of the Operating Partnership's
debt approximates fair value. The Operating Partnership's fixed and variable
rate debt is described in "Management's Discussion and Analysis of Financial
Condition and Results of Operations." At December 31, 1999, the Operating
Partnership had no interest rate caps or swaps. In conjunction with the issuance
of the May 1999 Notes, the Operating Partnership hedged its exposure to pricing
benchmarks so that the net cost to the Operating Partnership was 6.74% for the
2004 notes and 7.18% for the 2009 Notes. The Operating Partnership was released
from any further obligations under the hedge upon issuance of the May 1999
Notes. All of the Operating Partnership's debt is denominated in United States
dollars. The Operating Partnership's risk management policies do not provide for
the utilization of financial instruments for trading purposes and only minimal
use for hedging purposes.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Partners of Spieker Properties, L.P.:

We have audited the accompanying consolidated balance sheets of Spieker
Properties, L.P. (a California limited partnership) and subsidiaries as of
December 31, 1999 and 1998, and the related consolidated statements of
operations, Partners' Capital and cash flows for the years ended December 31,
1999, 1998 and 1997. These financial statements and the schedule referred to
below are the responsibility of the management of Spieker Properties, L.P. Our
responsibility is to express an opinion on these financial statements and the
schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Spieker Properties, L.P. and
subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for the years ended December 31, 1999, 1998 and
1997 in conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying schedule listed in the
index to the financial statements is presented for purposes as complying with
the Securities and Exchange Commission rules and is not a required part of the
basic financial statements. This information has been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1999 AND 1998
                    (dollars in thousands, except share data)



1.  ORGANIZATION AND BASIS OF PRESENTATION

    Spieker Properties, L.P. (the "Operating Partnership) a California limited
    partnership, was formed on November 10, 1993 and commenced on November 19,
    1993, when Spieker Properties, Inc. (the "Company"), the general partner in
    the Operating Partnership, completed its initial public offering ("IPO") on
    November 18, 1993. As of December 31, 1999, the Company owned an approximate
    88.0 percent general partnership interest in the Operating Partnership.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Consolidation

    The Operating Partnership's consolidated financial statements include the
    consolidated financial position of the Operating Partnership and its
    subsidiaries as of December 31, 1999 and 1998, and its consolidated results
    of operations and cash flows for the years ended December 31, 1999, 1998 and
    1997. The Operating Partnership's investment in Spieker Northwest, Inc. (an
    unconsolidated Preferred Unit subsidiary) and its investment in Spieker
    Griffin/W9 Associates, LLC are accounted for under the equity method. All
    significant intercompany balances and transactions have been eliminated in
    the consolidated financial statements.

    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 the property, legal fees, acquisition costs,
    capitalized interest, property taxes and other costs incurred during the
    period of construction. All acquisitions are recorded using the purchase
    method of accounting.

    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 Operating Partnership 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 comparable 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 December 31, 1999 and 1998, none
    of the carrying values of the properties exceeded their estimated fair
    values. As of December 31, 1999 and 1998, the properties are located
    primarily in California and the Pacific Northwest. As a result of this
    geographic concentration, the operations of these properties could be
    adversely affected by a recession or general economic downturn where these
    properties are located.



                                       39
<PAGE>   40

    The Operating Partnership owns mortgage loans that are secured by real
    estate. Certain loans are with an affiliate of the Company (see Note 4). The
    Company assesses possible impairment of these loans by reviewing the fair
    value of the underlying real estate. As of December 31, 1999, the estimated
    fair value of the underlying real estate was in excess of the Operating
    Partnership'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 the property is under construction and until all costs
    related to the property's development are complete.

    Land Held for Investment

    The Operating Partnership has costs related to land parcels that are either
    held for investment or are in the design and approval process. As of
    December 31, 1999, approximately $19,500 million of construction in process
    is associated with these land parcels.

    Property Held for Disposition

    The Operating Partnership includes in property held for disposition, certain
    properties that do not have a strategic fit in which management has decided
    to sell. Included in the value of the properties are all costs associated
    with acquiring the property, any construction in progress plus any direct
    assessments less the accumulated depreciation.

    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. Unamortized financing and leasing costs are charged to expense upon
    the early payment of financing or upon the early termination of the lease.

    Fair Value of Financial Instruments

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

    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, and investment in mortgages and management fee income.

    Net Income Per Unit

    Per unit amounts for the Operating Partnership are computed using the
    weighted average units outstanding during the period. Additionally, earnings
    used in the calculation are reduced by dividends owed to Series A, B, C, and
    E preferred stock holders and preferred operating partnership unit holders .
    The diluted weighted average units outstanding include the dilutive effect
    of options and other unit equivalents. The computation of the diluted
    earnings per unit for the years ended

    December 31, 1999 and 1998 does not include WCB Preferred units due to their
    antidilutive effect. The basic and diluted weighted average general partner
    units and limited partners' units outstanding for the years ended December
    31, 1999, 1998 and 1997 are as follows:

    Reclassifications

    Certain items in the 1998 and 1997 financial statements have been
    reclassified to conform to the 1999 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, 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.

10. INCOME TAXES

    The Company has elected to be taxed as a REIT pursuant to Section 856(c)(1)
    of the Code. As a REIT, the Company generally will not be subject to federal
    income tax to the extent that it distributes at least 95 percent of its
    taxable income to its stockholders. Additionally, REITs are subject to a
    number of organizational and operational requirements. If the Company fails
    to qualify as a REIT in any taxable year, the Company will be subject to
    federal and state income taxes (including any applicable alternative minimum
    taxes) based on its taxable income using respective corporate income tax
    rates. Even if the Company qualifies for taxation as a REIT, the Company may
    be subject to certain state and local taxes on its income and property. The
    Company may also be subject to federal income and excise taxes on its
    undistributed taxable income.

    Taxable income allocable to the Company, excluding minority interests, was
    $196,800 for the year ended December 31, 1999, $149,600 for 1998 and
    $103,300 for 1997. The taxable income allocable to the preferred unit
    holders was $32,829 for the year ended December 31, 1999, $29,234 for 1998
    and $13,144 for 1997.

    Differences between book and taxable income primarily result from timing
    differences. The timing differences include depreciation of tenant
    improvements, unearned rental income, non-cash compensation and certain
    property dispositions structured as tax-free exchanges.

    For the year ended December 31, 1999, approximately 2.87% of the dividends
    paid, represents a dividend taxable as a long-term capital gain and
    approximately 1.28% represents a dividend taxable as an Unrecaptured Section
    1250 Gain.

11. PARTNERS' CAPITAL

    Preferred Units

    The 1,000,000 shares of Series A Cumulative Convertible Preferred Stock rank
    senior to the Operating Partnership's Common Stock as to dividends and
    liquidation rights. The shares are convertible into 1,219,512 shares of the
    Operating Partnership's Common Stock and have voting rights equal to
    1,219,512 shares of Common Stock. The dividend per share, calculated on the
    converted numbers of shares, is equal to the Common Stock dividend, provided
    that the dividend yield on the preferred stock may not be less than the
    initial dividend rate thereof. Dividends are paid quarterly in arrears. With
    respect to the payment of dividends and amounts upon liquidation, the Series
    A Preferred Stock ranks on parity with the Operating Partnership's Series B,
    Series C and Series E Preferred Stocks and ranks senior to the Operating
    Partnership's Common Stock, Class B and Class C Common Stock.

    The Series B Preferred Stock dividends are paid quarterly in arrears at
    9.45% of the initial liquidation preference per annum. The Series B
    Preferred Stock is redeemable on or after December 11, 2000 at the option of
    the Operating Partnership in whole or in part at a redemption price of
    $25.00 per share, plus accrued and unpaid dividends. With respect to the
    payments of dividends and amounts upon liquidation, the Series B Preferred
    Stock ranks on parity with Company's Series A, Series C and Series E
    Preferred Stocks and ranks senior to the Operating Partnership's Common
    Stock, Class B and Class C Common Stock.

    The Series C Preferred Stock dividends are payable quarterly in arrears at
    an annual rate of 7.88% of the initial liquidation preference of $150,000.
    The Series C Preferred shares are redeemable after October 10, 2002 at the
    option of the Operating Partnership, in whole or in part, at a redemption
    price of $25.00 per share, plus accrued and unpaid dividends. With respect
    to the payments of dividends and amounts upon liquidation the Series C
    Preferred shares rank on parity to the Operating Partnership's Series A,
    Series B and Series E Preferred Stocks and ranks senior to the Operating
    Partnership's Common Stock, Class B and Class C Common Stock.

    In June 1998, the Operating Partnership sold 4,000,000 shares of Series E
    Cumulative Redeemable Preferred Stock for $25.00 per share. These shares are
    redeemable at the option of the Operating Partnership. Dividends are payable
    at an annual rate of 8.00% of the redeemable liquidation preference of
    $100,000. Net proceeds of $96,401 were used principally to repay borrowings
    on the unsecured line of credit and to fund the ongoing acquisition and
    development of property.

    Ownership Limitations

    To maintain its qualification as a REIT, not more than 50 percent of the
    value of the outstanding shares of the Operating Partnership may be owned,
    directly or indirectly, by five or fewer individuals (defined to include
    certain entities), applying certain constructive ownership rules. To help
    ensure that the Company will not fail this test, the Company Charter
    provides for certain restrictions on the transfer of the Common Stock to
    prevent further concentration of stock ownership. Moreover, to evidence
    compliance with these requirements, the Company must maintain records that
    disclose the actual ownership of its outstanding Common Stock and will
    demand written statements each year from the record holders of designated
    percentages of its Common Stock disclosing the actual owners of such Common
    Stock.

    Stockholders Rights Agreement

    On September 30, 1998, the Company paid a dividend of one right for each
    outstanding share of Common Stock of the Company held of record at the close
    of business on September 30, 1998 or issued thereafter prior to the
    Separation Time, as defined in the Rights Agreement referred to below. The
    rights were issued pursuant to the Stockholders' Protection Rights
    Agreement, dated as of September 30, 1998 between the Company and the Bank
    of New York, as Rights Agent.

12. EMPLOYMENT RETIREMENT AND STOCK PLANS

    Retirement Savings Plan

    Effective January 1, 1994, the Operating Partnership adopted a retirement
    savings plan pursuant to Section 401(k) of the Internal Revenue Code,
    whereby participants may contribute a percentage of compensation, but not in
    excess of the maximum allowed under the Code. The plan provides for a
    matching contribution by the Company, which amounted to $840 for the year
    ended December 31, 1999, $597 for 1998 and $393 for 1997. In addition, the
    Company may make additional contributions at the discretion of management.
    Management authorized additional contributions of $853 for the year ended
    December 31, 1999, $582 for 1998 and $337 for 1997.

    Stock Incentive Plan

    The Company has adopted the Spieker Properties, L.P. 1993 Stock Incentive
    Plan (the "Stock Incentive Plan") to provide incentives to attract and
    retain officers and key employees. Under the Plan as amended on May 22,
    1996, the number of shares available for option grant is 9.9% of the number
    of shares of Common Stock, on a fully converted basis, outstanding as of the
    last day of the immediately preceding quarter, reduced by the number of
    shares of Common Stock reserved for issuance through other stock
    compensation plans of the Company. The strike price on the shares granted is
    equal to the market price of the Company's stock at the grant date. Shares
    granted under this plan vest over four or five years.

    Directors Stock Option Plan

    On May 22, 1996, the Directors' Stock Option Plan was amended to increase
    the number of shares of Common Stock subject to automatic annual option
    grants to the Operating Partnership's independent directors from 500 shares
    to 4,000 shares, to increase the number of shares of Common Stock available
    for option grant from 30,000 to 150,000, and to provide that, in the event
    of a Change in Control, outstanding options will become fully vested. To
    date, 78,000 shares have been granted under the plan and 7,250 shares have
    been exercised.

    Stock Options

    The Operating Partnership applies APB 25 and related interpretations in
    accounting for its stock option plan. Accordingly, no compensation cost has
    been recognized. Had compensation cost for the plan been determined based on
    the fair value at the grant dates for awards under the plan consistent with
    the method prescribed by Statement of Financial Accounting Standard ("SFAS")
    No. 123, "Accounting for Stock-Based Compensation," the Operating
    Partnership's pro forma net income available to common stockholders would
    have been reduced by $2,761, $2,090 and $1,943 and pro forma basic and
    diluted earnings per share would have been reduced to $2.90, $2.85 and
    $2.08, and $2.05, $2.04 and $2.01, respectively, for the years ended
    December 31, 1999, 1998 and 1997.

    For these disclosure purposes, the fair value of each option grant is
    estimated on the date of grant using the Black-Scholes option-pricing model
    with the following weighted average assumptions used for grants in 1999 and
    1998, respectively; dividend yield of 6.1% and 6.6%; expected volatility of
    19.3% and 18.1%; expected lives of ten and six years; and risk-free interest
    rates of 5.8% and 4.6%.

    Restricted Stock

    Effective June 9, 1999, the Board of Directors passed a resolution
    authorizing the issuance of up to 3,164,935 restricted shares of common
    stock of the Company pursuant to Restricted Stock Agreements, and
    immediately issued 201,610 of the newly authorized shares in exchange for
    previously outstanding unvested restricted shares granted in 1997, 1998 and
    1999 under the Stock Incentive Plan. For the year ended on December 31,
    1999, a total of 202,711 restricted shares have been issued.

13. COMMITMENTS AND CONTINGENCIES

    Environmental Matters

    The Operating Partnership follows the policy of monitoring its properties
    for the presence of hazardous or toxic substances. The Operating Partnership
    is not aware of any environmental liability with respect to the properties
    that would have a material adverse effect on the Operating Partnership's
    business, assets or results of operations. There can be no assurance that
    such a material environmental liability does not exist. The existence of any
    such material environmental liability would have an adverse effect on the
    Operating Partnership's results of operations and cash flow.

    Lease Commitments

    The Operating Partnership has entered into operating ground leases on
    certain land parcels with periods ranging from 16 to 88 years. Future
    minimum rental payments required under non-cancelable operating ground
    leases in effect at December 31, 1999 are as follows:

</TABLE>

    The land on which three of the Operating Partnership'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 Operating
    Partnership 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 prepayment periods (18
    to 24 years).

    General Uninsured Losses

    The Operating Partnership carries commercial general liability, fire, flood,
    extended coverage and rental loss insurance with policy specifications,
    limits and deductibles customarily carried for similar properties. There
    are, however, certain types of extraordinary losses, which may be either
    uninsurable, or not economically insurable. Should an uninsured loss occur,
    the Operating Partnership could lose its investment in, and anticipated
    profits and cash flows from, a property.

    Certain of the properties are located in areas that are subject to
    earthquake activity; the Operating Partnership has therefore obtained excess
    earthquake insurance for those properties in higher risk earthquake areas.
    In the event of an earthquake, the Operating Partnership is insured for
    $300,000 of loss (less a deductible of 5% of total insured value per
    occurrence capped at $35,000 million), any losses in excess of $300,000 will
    be borne by the Operating Partnership.

14. SEGMENT INFORMATION

    The Operating Partnership has four reportable segments: Pacific Northwest;
    North-East Bay/Sacramento, California; Silicon Valley and Southern
    California. Each region has a Regional President who is directly responsible
    for managing all phases of the region's operations including acquisition,
    development, leasing and property management. Each reportable segment
    includes both office and industrial properties, which are leased to tenants,
    engaged in various types of businesses. The accounting policies of the four
    regions are the same as



                                       49
<PAGE>   50
    those described in the summary of significant accounting policies. The
    Operating Partnership evaluates performance based upon the combined net
    operating income of the properties in each segment. Each of the four
    operating regions consists of differing mixes of office and industrial
    properties. The revenue and net operating income for the regions is not
    comparable, given the differing mixes of properties within the regions.

    Significant information used by the Operating Partnership in the reportable
    segments for the twelve months ended December 31, 1999, 1998 and 1997 is as
    follows:

    The sum of quarterly financial data in 1999 and 1998 varies from the annual
    data due to rounding.

17. NEW ACCOUNTING PRONOUNCEMENT

    On June 15, 1998, the FASB issued Statement of Financial Accounting
    Standards No. 133, Accounting for Derivative Instruments and Hedging
    Activities. The Statement establishes accounting and reporting standards
    requiring that every derivative instrument (including certain derivative
    instruments embedded in other contracts) be recorded on the balance sheet as
    either an asset or liability measured at its fair value. The Statement
    requires that changes in the derivative's fair value be recognized currently
    in earnings unless specific hedge accounting criteria are met. Special
    accounting for qualifying hedges allows a derivative's gains and losses to
    offset related results on the hedged item in the income statement and
    requires that a company must formally document, designate and assess the
    effectiveness of transactions that receive hedge accounting.

    Statement No. 133 may become effective for the Operating Partnership
    beginning with the 2001 fiscal year and may not be applied retroactively.
    Management does not expect the impact of Statement No. 133 to be material to
    the consolidated financial statements. However, the Statement could increase
    volatility in earnings and other comprehensive income.

    In December 1999, the Securities and Exchange Commission issued Staff
    Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in Financial
    Statements. SAB 101 provides guidance on applying generally accepted
    accounting principles to revenue recognition issues in financial statements.
    The Operating Partnership will adopt SAB 101 as required in the first
    quarter 2000. Management does not expect the impact of SAB 101 to be
    material to the consolidated financial statements.

18. SUBSEQUENT EVENTS

    Subsequent to December 31, 1999, the Operating Partnership acquired two West
    Coast office properties totaling 335,000 square feet for a total investment
    of $74,500 million. These acquisitions were funded with a portion of the
    proceeds from the recent sale of the Operating Partnership's $193,000
    million industrial portfolio in Seattle, Washington. To date the Operating
    Partnership has closed on $156,000 million of the multi-phased sale of its
    $193,000 industrial portfolio in Seattle.

    On March 8, 2000 the Company announced that the Board of Directors declared
    a dividend of $0.70 per share of Common Stock. The dividend will be paid on
    April 20, 2000, to shareholders of record as of March 31, 2000. This is
    equivalent to an annualized dividend of $2.80 per share and represents a
    14.8 percent increase from the previous annualized dividend of $2.44.

                                   ARTICLE I.

                                  STOCKHOLDERS

SECTION 1.01. ANNUAL MEETING. The Corporation shall hold an annual meeting of
its stockholders to elect directors and transact any other business within its
powers, either at 10:00 a.m. on the last Thursday of May in each year if not a
legal holiday, or at such other time on such other day falling on or before the
30th day thereafter as shall be set by the Board of Directors. Except as the
Charter or statute provides otherwise, any business may be considered at an
annual meeting without the purpose of the meeting having been specified in the
notice. Failure to hold an annual meeting does not invalidate the Corporation's
existence or affect any otherwise valid corporate acts.

SECTION 1.02. SPECIAL MEETING. At any time in the interval between annual
meetings, a special meeting of the stockholders may be called by the Chairman of
the Board or the President or by a majority of the Board of Directors by vote at
a meeting or in writing (addressed to the Secretary of the Corporation) with or
without a meeting. Subject to the procedures set forth in Section 1.11 and this
Section, special meetings of the stockholders shall be called by the Secretary
at the request of stockholders only on the written request of stockholders
entitled to cast at least a majority of all the votes entitled to be cast at the
meeting. A request for a special meeting shall state the purpose of the meeting
and the matters proposed to be acted on at it. The Secretary shall inform the
stockholders who make the request of the reasonably estimated costs of preparing
and mailing a notice of the meeting and, on payment of these costs to the
Corporation, notify each stockholder entitled to notice of the meeting. The
Board of Directors shall have sole power to fix the date and time of the special
meeting.

SECTION 1.03. PLACE OF MEETINGS. Unless the Charter provides otherwise, meetings
of stockholders shall be held at such place as is set from time to time by the
Board of Directors.

SECTION 1.04. NOTICE OF MEETINGS; WAIVER OF NOTICE. Not less than ten nor more
than 90 days before each stockholders' meeting, the Secretary shall give written
notice of the meeting to each stockholder entitled to vote at the meeting and
each other stockholder entitled to notice of the meeting. The notice shall state
the time and place of the meeting and, if the meeting is a special meeting or
notice of the purpose is required by statute, the purpose of the meeting. Notice
is given to a stockholder when it is personally delivered to him or her, left at
his or her residence or usual place of business, or mailed to him or her at his
or her address as it appears on the records of the Corporation or transmitted to
the stockholder by electronic mail to any electronic mail address of the
stockholder or by any other electronic means. Notwithstanding the foregoing
provisions, each person who is entitled to notice waives notice if he or she
before or after the meeting signs a waiver of the notice which is filed with the
records of stockholders' meetings, or is present at the meeting in person or by
proxy.

SECTION 1.05. QUORUM; VOTING. Unless any statute or the Charter provides
otherwise, at a meeting of stockholders the presence in person or by proxy of
stockholders entitled to cast a majority of all the votes entitled to be cast at
the meeting constitutes a quorum, and a majority of all the votes cast at a
meeting at which a quorum is present is sufficient to approve any matter which
properly comes before the meeting, except that a plurality of all the votes cast
at a meeting at which a quorum is present is sufficient to elect a director.

SECTION 1.06. ADJOURNMENTS. Whether or not a quorum is present, a meeting of
stockholders convened on the date for which it was called may be adjourned from
time to time without further notice by a majority vote of the stockholders
present in person or by proxy to a date not more than 120 days after the
original record date. Any business which might have been transacted at the
meeting as originally notified may be deferred and transacted at any such
adjourned meeting at which a quorum shall be present.

                                      -65-

SECTION 1.07. GENERAL RIGHT TO VOTE; PROXIES. Unless the Charter provides for a
greater or lesser number of votes per share or limits or denies voting rights,
each outstanding share of stock, regardless of class, is entitled to one vote on
each matter submitted to a vote at a meeting of stockholders; however, a share
is not entitled to be voted if any installment payable on it is overdue and
unpaid. In all elections for directors, each share of stock may be voted for as
many individuals as there are directors to be elected and for whose election the
share is entitled to be voted. A stockholder may vote the stock the stockholder
owns of record either in person or by proxy. A stockholder may sign a writing
authorizing another person to act as proxy. Signing may be accomplished by the
stockholder or the stockholder's authorized agent signing the writing or causing
the stockholder's signature to be affixed to the writing by any reasonable
means, including facsimile signature. A stockholder may authorize another person
to act as proxy by transmitting, or authorizing the transmission of, an
authorization by a telegram, cablegram, datagram, electronic mail or any other
electronic or telephonic means to the person authorized to act as proxy or to
any other person authorized to receive the proxy authorization on behalf of the
person authorized to act as the proxy, including a proxy solicitation firm or
proxy support service organization. Unless a proxy provides otherwise, it is not
valid more than 11 months after its date. A proxy is revocable by a stockholder
at any time without condition or qualification unless the proxy states that it
is irrevocable and the proxy is coupled with an interest. A proxy may be made
irrevocable for so long as it is coupled with an interest. The interest with
which a proxy may be coupled includes an interest in the stock to be voted under
the proxy or another general interest in the Corporation or its assets or
liabilities.

SECTION 1.08. LIST OF STOCKHOLDERS. At each meeting of stockholders, a full,
true and complete list of all stockholders entitled to vote at such meeting,
showing the number and class of shares held by each and certified by the
transfer agent for such class or by the Secretary, shall be furnished by the
Secretary.

SECTION 1.09. CONDUCT OF BUSINESS. Nominations of persons for election to the
Board of Directors and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (a) pursuant to
the Corporation's notice of meeting, (b) by or at the direction of the Board of
Directors or (c) by any stockholder of the Corporation (i) who was a stockholder
of record at the time of giving notice(s) provided for in Section 1.11 and
Section 1.12, (ii) who is entitled to vote at the meeting and (iii) who complied
with the notice(s) procedures set forth in Section 1.11 and Section 1.12.
Nominations of persons for election to the Board of Directors and the proposal
of business to be considered by the stockholders may be made at a special
meeting of stockholders (a) only pursuant to the Corporation's notice of meeting
and (b), in the case of nominations of persons for election to the Board of
Directors, (i) by or at the direction of the Board of Directors or (ii) by any
stockholder of the Corporation (A) who was a stockholder of record at the time
of giving notice provided for in Section 1.11, (B) who is entitled to vote at
the meeting and (C) who complied with the notice procedures set forth in Section
1.11. The chairman of the meeting shall have the power and duty to determine
whether a nomination or any business proposed to be brought before the meeting
was made in accordance with the procedures set forth in Section 1.11, Section
1.12 and this Section and, if any proposed nomination or business is not in
compliance with Section 1.11, Section 1.12 and this Section, to declare that
such defective nomination or proposal be disregarded.

SECTION 1.10. CONDUCT OF VOTING. At all meetings of stockholders, unless the
voting is conducted by inspectors, the proxies and ballots shall be received,
and all questions touching the qualification of voters and the validity of
proxies, the acceptance or rejection of votes and procedures for the conduct of
business not otherwise specified by these Bylaws, the Charter or law, shall be
decided or determined by the chairman of the meeting. If demanded by
stockholders, present in person or by proxy, entitled to cast 10% in number of
votes entitled to be cast, or if ordered by the chairman of the meeting, the
vote upon any election or question shall be taken by ballot. Before any meeting
of the stockholders, the Board of Directors may appoint persons to act as
inspectors of election at the meeting and any adjournment thereof. If no
inspectors of election are so appointed, the chairman of the meeting may, and on
the request of stockholders, present in person or by proxy, entitled to cast 10%
in number of votes entitled to be cast, shall, appoint inspectors of election at
the meeting. The number of inspectors shall be either one or three. If
inspectors are appointed at a meeting on the request of stockholders, the
holders of a majority of shares present in person or by proxy shall determine
whether one or three inspectors are to be appointed. No candidate for election
as a director at a meeting shall serve as an inspector thereat. If any person
appointed as inspector fails to appear or fails or refuses to act, the chairman
of the meeting may, and upon the request of any stockholder shall, appoint a
person to fill that vacancy. The inspectors shall determine the number of shares
outstanding and the voting power of each,

                                      -66-

the shares represented at the meeting, the existence of a quorum, and the
authenticity, validity and effect of proxies; receive votes, ballots or
consents; hear and determine all challenges and questions in any way arising in
connection with the right to vote; count and tabulate all votes or consents;
determine when polls shall close; determine the result; and do any other acts
that may be proper to conduct the election or vote with fairness to all
stockholders. Unless so demanded or ordered, no vote need be by ballot and
voting need not be conducted by inspectors.

SECTION 1.11. ADVANCE NOTICE PROVISIONS FOR ELECTION OF DIRECTORS. Only persons
who are nominated in accordance with the following procedures shall be eligible
for election as directors of the Corporation. Nominations of persons for
election to the Board of Directors may be made at any annual meeting of
stockholders, or at any special meeting of stockholders called for the purpose
of electing directors, (a) by or at the direction of the Board of Directors (or
any duly authorized committee thereof) or (b) by any stockholder of the
Corporation (i) who is a stockholder of record on the date of the giving of the
notice provided for in this Section and on the record date for the determination
of stockholders entitled to vote at such meeting and (ii) who complies with the
notice procedures set forth in this Section. A stockholder's notice must be
delivered to or mailed and received by the Secretary at the principal executive
offices of the Corporation (a) in the case of an annual meeting, not less than

called for the purpose of electing directors, not later than the close of
business on the tenth day following the day on which notice of the date of the

owner, if any, on whose behalf the nomination is made, (ii) the class or series
and number of shares of capital stock of the Corporation which are owned
beneficially or of record by such stockholder and such beneficial owner, (iii) a
description of all arrangements or understandings between such stockholder and

notice must be accompanied by a written consent of each proposed nominee to be
named as a nominee and to serve as a director if elected. No person shall be
eligible for election as a director of the Corporation unless nominated in
accordance with the procedures set forth in this Section. If the chairman of the
meeting determines that a nomination was not made in accordance with the
foregoing procedures, the chairman of the meeting shall declare to the meeting
that the nomination was defective and such defective nomination shall be
disregarded. No adjournment or postponement of a meeting of stockholders shall
commence a new period for the giving of notice of a stockholder proposal

SECTION 1.12. ADVANCE NOTICE PROVISIONS FOR BUSINESS TO BE TRANSACTED AT ANNUAL

(or any duly authorized committee thereof), (b) otherwise properly brought
before the annual meeting by or at the direction of the Board of Directors (or

meeting of stockholders except business brought before the annual meeting in
accordance with the procedures set forth in Section 1.11 or in this Section,
provided, however, that once business has been properly brought before the
annual meeting in accordance with such procedures, nothing in Section 1.11 nor
in this Section shall be deemed to preclude discussion by any stockholder of any
such business. If the chairman of an annual meeting determines that business was
not properly brought before the annual meeting in accordance with the foregoing
procedures, the chairman of the meeting shall declare to the meeting that the
business was not properly brought before the meeting and such business shall not
be transacted. No adjournment or postponement of a meeting of stockholders shall
commence a new period for the giving of notice of a stockholder proposal
hereunder.

SECTION 1.13. INFORMAL ACTION BY STOCKHOLDERS. Any action required or permitted
to be taken at a meeting of stockholders may be taken without a meeting if there
is filed with the records of stockholders meetings an unanimous written consent
which sets forth the action and is signed by each stockholder entitled to vote

stockholder entitled to notice of the meeting but not entitled to vote at it.

SECTION 1.14. MEETING BY CONFERENCE TELEPHONE. Stockholders may participate in a
meeting by means of a conference telephone or similar communications equipment

                                   ARTICLE II.

                               BOARD OF DIRECTORS

SECTION 2.01. FUNCTION OF DIRECTORS. The business and affairs of the Corporation
shall be managed under the direction of its Board of Directors. All powers of
the Corporation may be exercised by or under authority of the Board of
Directors, except as conferred on or reserved to the stockholders by statute or
by the Charter or Bylaws.

SECTION 2.02. NUMBER OF DIRECTORS. The Corporation shall have at least three
directors; provided that, if there is no stock outstanding, the number of
directors may be less than three but not less than one, and, if there is stock
outstanding and so long as there are less than three stockholders, the number of
directors may be less than three but not less than the number of stockholders.
The Corporation shall have the number of directors provided in the Charter until
changed as herein provided. Two-thirds of the entire Board of Directors may
alter the number of directors set by the Charter to not exceeding 25 nor less
than the minimum number then permitted herein, but the action may not affect the
tenure of office of any director.

SECTION 2.03. ELECTION AND TENURE OF DIRECTORS. The directors shall be divided
into three classes as nearly equal in number as possible. At each successive
annual meeting of stockholders, the holders of stock present in person or by
proxy at such meeting and entitled to vote thereat shall elect members of each
successive class to serve for three year terms and until their successors are
elected and qualify. If the number of directors is changed, any increase or
decrease shall be apportioned among the classes so as to maintain the number of
directors in each class as nearly equal as possible, and any additional director
of any class shall, subject to Section 2.05, hold office for a term that shall
coincide with the remaining term of that class, but in no case shall a decrease
in the number of directors shorten the term of any incumbent director.

SECTION 2.04. REMOVAL OF DIRECTOR. Any director or the entire Board of Directors
may be removed only in accordance with the provisions of the Charter. For
purposes of the foregoing, "cause," shall mean only (i) conviction of a felony,
(ii) declaration of unsound mind by order of a court, (iii) gross dereliction of
duty, (iv) conviction of any act involving moral turpitude or (v) commission of
an act that constitutes intentional misconduct or a knowing violation of law if
such action in either event results both in an improper substantial personal
benefit to the director and in a material injury to the Corporation.

SECTION 2.05. VACANCY ON BOARD OF DIRECTORS. Subject to the rights of the
holders of any class or series of stock separately entitled to elect one or more
directors, the stockholders may elect a successor to fill a vacancy on the Board
of Directors which results from the removal of a director. A director elected by
the stockholders to fill a vacancy which results from the removal of a director
serves for the balance of the term of the removed director. Subject to the
rights of the holders of any class of stock separately entitled to elect one or
more directors, a majority of the remaining directors, whether or not sufficient
to constitute a quorum, may fill a vacancy on the Board of Directors which
results from any cause except an increase in the number of directors, and a
majority of the entire Board of Directors may fill a vacancy which results from
an increase in the number of directors. A director elected by the Board of
Directors to fill a vacancy serves until the next annual meeting of stockholders
and until his or her successor is elected and qualifies.

SECTION 2.06. REGULAR MEETINGS. After each meeting of stockholders at which
directors shall have been elected, the Board of Directors shall meet as soon
thereafter as practicable for the purpose of organization and the transaction of
other business. In the event that no other time and place are specified by
resolution of the Board of Directors or announced by the President or the
Chairman of the Board at such stockholders meeting, the Board of Directors shall
meet immediately following the close of, and at the place of, such stockholders
meeting. Any other regular meeting of the Board of Directors shall be held on
such date and time and at such place as may be designated from time to time by
the Board of Directors. No notice of such meeting following a stockholders
meeting or any other regular meeting shall be necessary if held as hereinabove
provided.

SECTION 2.07. SPECIAL MEETINGS. Special meetings of the Board of Directors may
be called at any time by the Chairman of the Board or the President or by a
majority of the Board of Directors by vote at a meeting, or in writing

                                      -69-
<PAGE>   6

with or without a meeting. A special meeting of the Board of Directors shall be
held on such date and at any place as may be designated from time to time by the
Board of Directors. In the absence of designation such meeting shall be held at
such place as may be designated in the call.

SECTION 2.08. NOTICE OF MEETING. Except as provided in Section 2.06, the
Secretary shall give notice to each director of each regular and special meeting
of the Board of Directors. The notice shall state the time and place of the
meeting. Notice is given to a director when it is delivered personally to him or
her, left at his or her residence or usual place of business, or sent by
telegraph, facsimile transmission or telephone, at least 24 hours before the
time of the meeting or, in the alternative by mail to his or her address as it
shall appear on the records of the Corporation, at least 72 hours before the
time of the meeting. Unless these Bylaws or a resolution of the Board of
Directors provides otherwise, the notice need not state the business to be
transacted at or the purposes of any regular or special meeting of the Board of
Directors. No notice of any meeting of the Board of Directors need be given to
any director who attends except where a director attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened, or to any director who, in writing
executed and filed with the records of the meeting either before or after the
holding thereof, waives such notice. Any meeting of the Board of Directors,
regular or special, may adjourn from time to time to reconvene at the same or
some other place, and no notice need be given of any such adjourned meeting
other than by announcement.

SECTION 2.09. QUORUM; ACTION BY DIRECTORS. A majority of the entire Board of
Directors shall constitute a quorum for the transaction of business. In the
absence of a quorum, the directors present by majority vote and without notice
other than by announcement may adjourn the meeting from time to time until a
quorum shall attend. At any such adjourned meeting at which a quorum shall be
present, any business may be transacted which might have been transacted at the
meeting as originally notified. Unless statute or the Charter or Bylaws requires
a greater proportion, the action of a majority of the directors present at a
meeting at which a quorum is present is action of the Board of Directors. Any
action required or permitted to be taken at a meeting of the Board of Directors
may be taken without a meeting, if an unanimous written consent which sets forth
the action is signed by each member of the Board of Directors and filed with the
minutes of proceedings of the Board of Directors.

SECTION 2.10. MEETING BY CONFERENCE TELEPHONE. Members of the Board of Directors
may participate in a meeting by means of a conference telephone or similar
communications equipment if all persons participating in the meeting can hear
each other at the same time. Participation in a meeting by these means
constitutes presence in person at a meeting.

SECTION 2.11. COMPENSATION. By resolution of the Board of Directors a fixed sum
and expenses, if any, for attendance at each regular or special meeting of the
Board of Directors or of committees thereof, and other compensation for their
services as such or on committees of the Board of Directors, may be paid to
directors. Directors who are full-time employees of the Corporation need not be
paid for attendance at meetings of the Board of Directors or committees thereof
for which fees are paid to other directors. A director who serves the
Corporation in any other capacity also may receive compensation for such other
services, pursuant to a resolution of the directors.

SECTION 2.12. RESIGNATION. Any director may resign at any time by sending a
written notice of such resignation to the home office of the Corporation
addressed to the Chairman of the Board or the President. Unless otherwise
specified therein such resignation shall take effect upon receipt thereof by the
Chairman of the Board or the President.

SECTION 2.13. PRESUMPTION OF ASSENT. A director of the Corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be presumed to have assented to the action taken unless
his or her dissent or abstention shall be entered in the minutes of the meeting
or unless he or she shall file his or her written dissent to such action with
the person acting as the secretary of the meeting before the adjournment thereof
or shall forward such dissent by registered mail to the Secretary of the
Corporation immediately after the adjournment of the meeting. Such right to
dissent shall not apply to a director who votes in favor of such action or fails
to make his dissent known at the meeting.

                                      -70-

SECTION 2.14. ADVISORY DIRECTORS. The Board of Directors may by resolution
appoint advisory directors to the Board of Directors, who may also serve as
directors emeriti, and shall have such authority and receive such compensation
and reimbursement as the Board of Directors shall provide. Advisory directors or
directors emeriti shall not have the authority to participate by vote in the
transaction of business.


                                  ARTICLE III.

                                   COMMITTEES

SECTION 3.01. COMMITTEES. The Board of Directors may appoint from among its
members an Executive Committee and other committees composed of one or more
directors and delegate to these committees any of the powers of the Board of
Directors, except the power to authorize dividends on stock, elect directors,
issue stock other than as provided in the next sentence, recommend to the
stockholders any action which requires stockholder approval, amend these Bylaws,
or approve any merger or share exchange which does not require stockholder
approval. If the Board of Directors has given general authorization for the
issuance of stock providing for or establishing a method or procedure for
determining the maximum number of shares to be issued, a committee of the Board
of Directors, in accordance with that general authorization or any stock option
or other plan or program adopted by the Board of Directors, may authorize or fix
the terms of stock subject to classification or reclassification and the terms
on which any stock may be issued, including all terms and conditions required or
permitted to be established or authorized by the Board of Directors.

SECTION 3.02. COMMITTEE PROCEDURE. Each committee may fix rules of procedure for
its business. A majority of the members of a committee shall constitute a quorum
for the transaction of business and the act of a majority of those present at a
meeting at which a quorum is present shall be the act of the committee. The
members of a committee present at any meeting, whether or not they constitute a
quorum, may appoint a director to act in the place of an absent member. Any
action required or permitted to be taken at a meeting of a committee may be
taken without a meeting, if an unanimous written consent which sets forth the
action is signed by each member of the committee and filed with the minutes of
the committee. The members of a committee may conduct any meeting thereof by
conference telephone in accordance with the provisions of Section 2.10.

SECTION 3.03. EMERGENCY. In the event of a state of disaster of sufficient
severity to prevent the conduct and management of the affairs and business of
the Corporation by its directors and officers as contemplated by the Charter and
these Bylaws, any two or more available members of the then incumbent Executive
Committee shall constitute a quorum of that Committee for the full conduct and
management of the affairs and business of the Corporation in accordance with the
provisions of Section 3.01. In the event of the unavailability, at such time, of
a minimum of two members of the then incumbent Executive Committee, the
available directors shall elect an Executive Committee consisting of any two
members of the Board of Directors, whether or not they be officers of the
Corporation, which two members shall constitute the Executive Committee for the
full conduct and management of the affairs of the Corporation in accordance with
the foregoing provisions of this Section. This Section shall be subject to
implementation by resolution of the Board of Directors passed from time to time
for that purpose, and any provisions of these Bylaws (other than this Section)
and any resolutions which are contrary to the provisions of this Section or to
the provisions of any such implementary resolutions shall be suspended until it
shall be determined by any interim Executive Committee acting under this Section
that it shall be to the advantage of the Corporation to resume the conduct and
management of its affairs and business under all the other provisions of these
Bylaws.


                                   ARTICLE IV.

                                    OFFICERS

chief executive officer and the President shall serve as chief operating
officer. In the absence of the Chairman of the Board, or if there be none, the
President shall be the chief executive officer. The same person may hold both

be a director, and the other officers may be directors.

she may execute, in the name of the Corporation, all authorized deeds,
mortgages, bonds, contracts or other instruments, except in cases in which the
signing and execution thereof shall have been expressly delegated to some other
officer or agent of the Corporation. In general, he or she shall perform such
other duties customarily performed by a president of a corporation and shall
perform such other duties and have such other powers as are from time to time
assigned to him or her by the Board of Directors or the chief executive officer
of the Corporation.

SECTION 4.04. VICE-PRESIDENTS. The Vice-President or Vice-Presidents, at the
request of the chief executive officer or the President, or in the President's
absence or during his or her inability to act, shall perform the duties and
exercise the functions of the President, and when so acting shall have the
powers of the President. If there be more than one Vice-President, the Board of
Directors may determine which one or more of the Vice-Presidents shall perform
any of such duties or exercise any of such functions, or if such determination
is not made by the Board of Directors, the chief executive officer, or the
President may make such determination; otherwise any of the Vice-Presidents may
perform any of such duties or exercise any of such functions. Each
Vice-President shall perform such other duties and have such other powers, and

from time to time assigned to them by the Board of Directors, the chief
executive officer, or the President.

duties as are from time to time assigned to them by the Board of Directors, the

SECTION 4.08. ELECTION, TENURE AND REMOVAL OF OFFICERS. The Board of Directors
shall elect the officers of the Corporation. The Board of Directors may from
time to time authorize any committee or officer to appoint assistant and
subordinate officers. Election or appointment of an officer, employee or agent
shall not of itself create contract rights. All officers shall be appointed to
hold their offices, respectively, during the pleasure of the Board of Directors.
The Board of Directors (or, as to any assistant or subordinate officer, any
committee or officer authorized by the Board of Directors) may remove an officer
at any time. The removal of an officer does not prejudice any of his or her
contract rights. The Board of Directors (or, as to any assistant or subordinate
officer, any committee or officer authorized by the Board of Directors) may fill
a vacancy which occurs in any office for the unexpired portion of the term.

SECTION 4.09. COMPENSATION. The Board of Directors shall have power to fix the
salaries and other compensation and remuneration, of whatever kind, of all
officers of the Corporation. No officer shall be prevented from receiving such

Corporation. The Board of Directors may authorize any committee or officer, upon
whom the power of appointing assistant and subordinate officers may have been
conferred, to fix the salaries, compensation and remuneration of such assistant
and subordinate officers.


                                   ARTICLE V.

SECTION 5.01. CONFERRING DIVISIONAL TITLES. The Board of Directors may from time
to time confer upon any employee of a division of the Corporation the title of
President, Vice President, Treasurer or Controller of such division or any other
title or titles deemed appropriate, or may authorize the Chairman of the Board
or the President to do so. Any such titles so conferred may be discontinued and
withdrawn at any time by the Board of Directors, or by the Chairman of the Board
or the President if so authorized by the Board of Directors. Any employee of a
division designated by such a divisional title shall have the powers and duties
with respect to such division as shall be prescribed by the Board of Directors,
the Chairman of the Board or the President.

SECTION 5.02. EFFECT OF DIVISIONAL TITLES. The conferring of divisional titles
shall not create an office of the Corporation under Article IV unless
specifically designated as such by the Board of Directors; but any person who is

                                   ARTICLE VI.

                                      STOCK

SECTION 6.01. CERTIFICATES FOR STOCK. The Board of Directors may determine to
issue certificated or uncertificated shares of capital stock and other
securities of the Corporation. For certificated stock, each stockholder is
entitled to certificates which represent and certify the shares of stock he or
she holds in the Corporation. Each stock certificate shall include on its face
the name of the Corporation, the name of the stockholder or other person to whom
it is issued, and the class of stock and number of shares it represents. It
shall also include on its face or back (a) a statement of any restrictions on
transferability and a statement of the designations and any preferences,
conversion and other rights, voting powers, restrictions, limitations as to
dividends, qualifications, and terms and conditions of redemption of the stock
of each class which the Corporation is authorized to issue, of the differences
in the relative rights and preferences between the shares of each series of a
preferred or special class in series which the Corporation is authorized to
issue, to the extent they have been set, and of the authority of the Board of
Directors to set the relative rights and preferences of subsequent series of a
preferred or special class of stock or (b) a statement

                                      -73-
<PAGE>   10

which provides in substance that the Corporation will furnish a full statement
of such information to any stockholder on request and without charge. Such
request may be made to the Secretary or to its transfer agent. Except as
provided in the Maryland Uniform Commercial Code - Investment Securities, the
fact that a stock certificate does not contain or refer to a restriction on
transferability that is adopted after the date of issuance does not mean that
the restriction is invalid or unenforceable. Upon the issuance of uncertificated
shares of capital stock, the Corporation shall send the stockholder a written
statement of the same information required above on the certificate and by the
Maryland Uniform Commercial Code Investment Securities. It shall be in such
form, not inconsistent with law or with the Charter, as shall be approved by the
Board of Directors or any officer or officers designated for such purpose by
resolution of the Board of Directors. Each stock certificate shall be signed by
the Chairman of the Board, the President, or a Vice-President, and countersigned
by the Secretary, an Assistant Secretary, the Treasurer, or an Assistant
Treasurer. Each certificate may be sealed with the actual corporate seal or a
facsimile of it or in any other form and the signatures may be either manual or
facsimile signatures. A certificate is valid and may be issued whether or not an
officer who signed it is still an officer when it is issued. A certificate may
not be issued until the stock represented by it is fully paid.

SECTION 6.02. TRANSFERS. The Board of Directors shall have power and authority
to make such rules and regulations as it may deem expedient concerning the
issue, transfer and registration of certificates of stock; and may appoint
transfer agents and registrars thereof. The duties of transfer agent and
registrar may be combined.

SECTION 6.03. RECORD DATES OR CLOSING OF TRANSFER BOOKS. The Board of Directors
may, and shall have the sole power to, set a record date or direct that the
stock transfer books be closed for a stated period for the purpose of making any
proper determination with respect to stockholders, including which stockholders
are entitled to request a special meeting of stockholders, notice of a meeting
of stockholders, vote at a meeting of stockholders, receive a dividend, or be
allotted other rights. The record date may not be prior to the close of business
on the day the record date is fixed nor, subject to Section 1.06, more than 90
days before the date on which the action requiring the determination will be
taken; the transfer books may not be closed for a period longer than 20 days;
and, in the case of a meeting of stockholders, the record date or the closing of
the transfer books shall be at least ten days before the date of the meeting.
Any shares of the Corporation's own stock acquired by the Corporation between
the record date for determining stockholders entitled to notice of or to vote at
a meeting of stockholders and the time of the meeting may be voted at the
meeting by the holder of record as of the record date and shall be counted in
determining the total number of outstanding shares entitled to be voted at the
meeting.

SECTION 6.04. STOCK LEDGER. The Corporation shall maintain a stock ledger which
contains the name and address of each stockholder and the number of shares of
stock of each class which the stockholder holds. The stock ledger may be in
written form or in any other form which can be converted within a reasonable
time into written form for visual inspection. The original or a duplicate of the
stock ledger shall be kept at the offices of a transfer agent for the particular
class of stock, or, if none, at the principal office in the State of Maryland or
the principal executive offices of the Corporation.

SECTION 6.05. CERTIFICATION OF BENEFICIAL OWNERS. The Board of Directors may
adopt by resolution a procedure by which a stockholder of the Corporation may
certify in writing to the Corporation that any shares of stock registered in the
name of the stockholder are held for the account of a specified person other
than the stockholder. The resolution shall set forth the class of stockholders
who may certify; the purpose for which the certification may be made; the form
of certification and the information to be contained in it; if the certification
is with respect to a record date or closing of the stock transfer books, the
time after the record date or closing of the stock transfer books within which
the certification must be received by the Corporation; and any other provisions
with respect to the procedure which the Board of Directors considers necessary
or desirable. On receipt of a certification which complies with the procedure
adopted by the Board of Directors in accordance with this Section, the person
specified in the certification is, for the purpose set forth in the
certification, the holder of record of the specified stock in place of the
stockholder who makes the certification.

SECTION 6.06. LOST STOCK CERTIFICATES. The Board of Directors may determine the
conditions for issuing a new stock certificate in place of one which is alleged
to have been lost, stolen, or destroyed, or the Board of Directors may delegate
such power to any officer or officers of the Corporation. In their discretion,
the Board of Directors or

                                      -74-
<PAGE>   11

such officer or officers may require the owner of the certificate to give bond,
with sufficient surety, to indemnify the Corporation against any loss or claim
arising as a result of the issuance of a new certificate. In their discretion,
the Board of Directors or such officer or officers may refuse to issue such new
certificate save upon the order of some court having jurisdiction in the
premises.

SECTION 6.07. EXEMPTION FROM CONTROL SHARE ACQUISITION STATUTE. The provisions
of Sections 3-701 to 3-709 of the Maryland General Corporation Law shall not
apply to any share of the capital stock of the Corporation. Such shares of
capital stock are exempted from such Sections to the fullest extent permitted by
Maryland law.


                                  ARTICLE VII.

Vice-President, an Assistant Vice-President, the Treasurer, an Assistant
Treasurer, the Secretary or an Assistant Secretary.

SECTION 7.02. ANNUAL STATEMENT OF AFFAIRS. The President or chief accounting
officer shall prepare annually a full and correct statement of the affairs of
the Corporation, to include a balance sheet and a financial statement of
operations for the preceding fiscal year. The statement of affairs shall be
submitted at the annual meeting of the stockholders and, within 20 days after
the meeting, placed on file at the Corporation's principal office.

SECTION 7.03. FISCAL YEAR. The fiscal year of the Corporation shall be the 12
calendar months period ending December 31 in each year, unless otherwise
provided by the Board of Directors.

SECTION 7.04. DIVIDENDS. If declared by the Board of Directors at any meeting

in shares of the capital stock of the Corporation, unless such dividend is
contrary to law or to a restriction contained in the Charter.

SECTION 7.06. LOANS. No loans shall be contracted on behalf of the Corporation
and no evidence of indebtedness shall be issued in its name unless authorized by
the Board of Directors. Such authority may be general or confined to specific

shall be deposited from time to time to the credit of the Corporation in any of

                                 INDEMNIFICATION

SECTION 8.01. PROCEDURE. Any indemnification, or payment of expenses in advance
of the final disposition of any proceeding, shall be made promptly, and in any
event within 60 days, upon the written request of the director or officer
entitled to seek indemnification (the "Indemnified Party"). The right to
indemnification and advances hereunder shall be enforceable by the Indemnified
Party in any court of competent jurisdiction, if (i) the Corporation denies such
request, in whole or in part, or (ii) no disposition thereof is made within 60
days. The Indemnified Party's costs and expenses incurred in connection with
successfully establishing his or her right to indemnification, in whole or in
part, in any such action shall also be reimbursed by the Corporation. It shall
be a defense to any action for advance for expenses that (a) a determination has
been made that the facts then known to those making the determination would
preclude indemnification or (b) the Corporation has not received both (i) an
undertaking as required by law to repay such advances in the event it shall
ultimately be determined that the standard of conduct has not been met and (ii)
a written affirmation by the Indemnified Party of such Indemnified Party's good
faith belief that the standard of conduct necessary for indemnification by the
Corporation has been met.

                                      -75-
<PAGE>   12

SECTION 8.02. EXCLUSIVITY, ETC. The indemnification and advance of expenses
provided by the Charter and these Bylaws shall not be deemed exclusive of any
other rights to which a person seeking indemnification or advance of expenses
may be entitled under any law (common or statutory), or any agreement, vote of
stockholders or disinterested directors or other provision that is consistent
with law, both as to action in his or her official capacity and as to action in
another capacity while holding office or while employed by or acting as agent
for the Corporation, shall continue in respect of all events occurring while a
person was a director or officer after such person has ceased to be a director
or officer, and shall inure to the benefit of the estate, heirs, executors and
administrators of such person. The Corporation shall not be liable for any
payment under this Bylaw in connection with a claim made by a director or
officer to the extent such director or officer has otherwise actually received
payment under insurance policy, agreement, vote or otherwise, of the amounts
otherwise indemnifiable hereunder. All rights to indemnification and advance of
expenses under the Charter of the Corporation and hereunder shall be deemed to
be a contract between the Corporation and each director or officer of the
Corporation who serves or served in such capacity at any time while this Bylaw
is in effect. Nothing herein shall prevent the amendment of this Bylaw, provided
that no such amendment shall diminish the rights of any person hereunder with
respect to events occurring or claims made before its adoption or as to claims
made after its adoption in respect of events occurring before its adoption. Any
repeal or modification of this Bylaw shall not in any way diminish any rights to
indemnification or advance of expenses of such director or officer or the
obligations of the Corporation arising hereunder with respect to events
occurring, or claims made, while this Bylaw or any provision hereof is in force.

SECTION 8.03. SEVERABILITY; DEFINITIONS. The invalidity or unenforceability of
any provision of this Article VIII shall not affect the validity or
enforceability of any other provision hereof. The phrase "this Bylaw" in this
Article VIII means this Article VIII in its entirety.


                                   ARTICLE IX.

                                SUNDRY PROVISIONS

SECTION 9.01. BOOKS AND RECORDS. The Corporation shall keep correct and complete
books and records of its accounts and transactions and minutes of the
proceedings of its stockholders and Board of Directors and of any executive or
other committee when exercising any of the powers of the Board of Directors. The
books and records of the Corporation may be in written form or in any other form
which can be converted within a reasonable time into written form for visual
inspection. Minutes shall be recorded in written form but may be maintained in
the form of a reproduction. The original or a certified copy of these Bylaws
shall be kept at the principal office of the Corporation.

SECTION 9.02. CORPORATE SEAL. The Board of Directors shall provide a suitable
seal, bearing the name of the Corporation, which shall be in the charge of the
Secretary. The Board of Directors may authorize one or more duplicate seals and
provide for the custody thereof. If the Corporation is required to place its
corporate seal to a document, it is sufficient to meet the requirement of any
law, rule, or regulation relating to a corporate seal to place the word "(seal)"
adjacent to the signature of the person authorized to sign the document on
behalf of the Corporation.

SECTION 9.03. BONDS. The Board of Directors may require any officer, agent or
employee of the Corporation to give a bond to the Corporation, conditioned upon
the faithful discharge of his or her duties, with one or more sureties and in
such amount as may be satisfactory to the Board of Directors.

SECTION 9.04. VOTING STOCK IN OTHER CORPORATIONS. Stock of other corporations or
associations, registered in the name of the Corporation, may be voted by the
President, a Vice-President, or a proxy appointed by either of them. The Board
of Directors, however, may by resolution appoint some other person to vote such
shares, in which case such person shall be entitled to vote such shares upon the
production of a certified copy of such resolution.

SECTION 9.05. MAIL. Any notice or other document which is required by these
Bylaws to be mailed shall be deposited in the United States mails, postage
prepaid.

                                      -76-
<PAGE>   13

SECTION 9.06. CONTRACTS AND AGREEMENTS. To the extent permitted by applicable
law, and except as otherwise prescribed by the Charter or these Bylaws, the
Board of Directors may authorize any officer, employee or agent of the
Corporation to enter into any contract or execute and deliver any instrument in
the name of and on behalf of the Corporation. Such authority may be general or
confined to specific instances. A person who holds more than one office in the
Corporation may not act in more than one capacity to execute, acknowledge, or
verify an instrument required by law to be executed, acknowledged, or verified
by more than one officer.

SECTION 9.07. RELIANCE. Each director and officer of the Corporation shall, in
the performance of his or her duties with respect to the Corporation, be
entitled to rely on any information, opinion report or statement, including
financial statement or other financial data, prepared or presented by an officer
or employee of the Corporation whom the director or officer reasonably believes
to be reliable and competent in the matters presented, by a lawyer, certified
public accountant or other person as to a matter which the director or officer
reasonably believes to be within the person's professional or expert competence
or by a committee of the Board of Directors on which the director does not
serve, as to a matter within its designated authority, if the director believes
the committee to merit confidence.

SECTION 9.08. AMENDMENTS. In accordance with the Charter, these Bylaws may be
repealed, altered, amended or rescinded and new bylaws may be adopted (a) by the
stockholders of the Corporation (considered for this purpose as one class) by
the affirmative vote of not less than 80% of all the votes entitled to be cast
by the outstanding shares of capital stock of the Corporation generally in the
election of directors which are cast on the matter at any meeting of the
stockholders called for that purpose (provided that notice of such proposal is
included in the notice of such meeting) or (b) by the Board of Directors by the
affirmative vote of not less than two-thirds of the Board of Directors at a
meeting held in accordance with the provisions of these Bylaws.
