2007 Annual Report

“As owners and managers of Real Estate, we will maximize
shareholder value, by providing quality service in a creative
atmosphere of teamwork among our employees, customers and
communities.”

James C. Mastandrea,
Chairman and Chief Executive Officer

Dear Shareholder:

2007 was dedicated to rebuilding and preparing for the opportunities ahead. We focused on
attracting new tenants, leasing more space, improving our properties and earning higher rents.
As a result, we succeeded in increasing our occupancy and revenue over previous years.

This year brings new challenges, a fragile credit market roiled by the sub-prime debacle, and
the uncertainty about the presidential election outcome. We invested in our properties to make
them more attractive and to attract better tenants. Thus, Whitestone is positioned solidly to
weather any storms this year and capitalize on new opportunities.

Culture and Philosophy
The culture and philosophy at Whitestone is to enhance shareholder value by focusing on our
tenants and real estate communities. We pursue excellence in real estate
employees,
through developing our team, establishing prompt financial measurement
management
systems, and then measuring our results against benchmarks. We believe that well-trained
employees guided by sound financial information can make effective, timely decisions. The
result: Professional real estate management that enhances shareholder equity.

We give our 48 employees the respect they merit and the tools they need. We mentor their
development and review them on a regular basis, and we expect in return that they put
shareholder interests first. Though there were no salary increases in 2007, we lost none of the
management team that joined us from the previous property manager and overall turnover was
about 21% as compared to the industry average of 30%. We have focused on enhancing the
depth and breadth of the management team. The Whitestone REIT Executive Management
Leadership Training Program will graduate its first class of 17 this spring. These managers
have completed more than 40 hours of real estate education, taught both by in-house and
outside professionals, such as a nationally recognized real estate valuation expert, a highly
respected management consultant, and an internationally acclaimed architect.

To decrease voluntary tenant attrition by at least 20%, which we believe will result in a cashflow
improvement
in the range of $600,000-to-$800,000 during 2008, Whitestone initiated a
proactive tenant relations improvement program. To accomplish this, we have emphasized a
policy of quality service and worked hard to maintain good relations with our tenants.

And, our tenants appreciate it. For example, Soloman Ruth of Qwik Wash Laundry at Holly
Knight retail plaza, wrote us recently, “From 2001 to 2006, Qwik Wash Laundry had a
difficult time trying to cultivate and build a good landlord-tenant relationship. We would like
to extend our heartfelt thanks to Ms. Cindy Clothier (Whitestone’s property manager) for

helping us build the kind of landlord-tenant relationship [this past year] that we were trying to
build from day one. After all the pain and stress we had to endure, it is fair to say that
Ms. Clothier has added years to my life.”

Similarly, we are working hard to improve our relations with our real estate industry
colleagues.

For example, good relations with real estate brokers help us to sign more profitable leases.
Testifying to our success so far, Robert Avery, president of Houston lease broker, Alta
Commercial Real Estate Services, Inc., recently wrote about Whitestone’s Senior Leasing
Agent Gary Triplett, “During the negotiations I always felt that, while you exclusively
represented the interests of Whitestone, you treated Mr. Daly and me in a professional,
respectful manner. Some building owners in Houston apparently do not understand what it
takes to bring assets to full occupancy and I believe your company will beat those owners if
you maintain the same leasing strategy and caring attitude I experienced during our work
together.”

The Benefits of Internalized Management
One of our most important improvements has been to internalize the property management
function. The Board of Trustees refused to buy the former property management operation for
the offering price of $10 million, and instead established Whitestone REIT’s own property
management group. It cost us less than $250,000 for furniture, fixtures, computers, phone
system, and offices to establish the division, considerably less than paying an outside manager
or buying that outside manager for $10 million. Additionally, our administrative costs should
diminish as a percentage of revenues compared to the increasing amounts that would have
been paid to an outside manager as we continue to grow revenues, and we provide our
shareholders complete “transparency.”

Better Financial Controls Lead to Better Decisions
Importantly, to manage property well, the managers must have the company’s financial
information readily and quickly available. We established financial controls that enable us to
analyze Whitestone’s performance monthly. Our accounting and systems group is now
producing consolidated financial statements within ten days from the time we close our books
each month, providing decision-making data in a timely fashion. Our goal is to reduce the
time to five days.

We make decisions, before we spend shareholders’ money, after examining the costs versus
the benefits. We compare our results against our expectations and previous performance Our
senior management team meets weekly to review strategic business issues. In addition, we
have group operating, leasing and property management meetings. This flow of information
minimizes surprises and helps us to react quickly to capitalize on emerging trends or to refine
prior decisions.

An Upturn in New Leases Written
Our leasing group performed beyond expectations in 2007, considering the challenges it faced.

Indications of this superior performance include:

• New leases written in 2007 were $42 million, 110% greater than the $20 million in

new leases signed in 2006.

• The amount of rent-per-occupied square foot rose 8% in the fourth quarter of 2007

from the year-earlier period.

• Our occupancy rate reached 86.2%, up 4.5 percentage points from 81.7% in June
(see graph of Historic

2007 for properties owned for more than one year
Occupancy).

Much of this increase in occupancy occurred at the end of 2007, thus the full year impact on
revenue of $1.7 million will be seen in 2008.

Maintaining Property Values and Functionality
In order to achieve a higher level of rent per square foot, we invested in improving the
properties to attract higher quality tenants and made significant outlays to take care of deferred
tenants. Our property

management group completed tenant improvements on more than 800,000 square feet of new
and renewed leases, spending $1 million more in property operations,
repairs, and
maintenance in 2007 than last year and invested another $2 million in capital improvements.

By the end of 2007, our tenants and vendors knew that we cared about their businesses and
that we wanted them to succeed. Interest in our properties rose and prospective tenants
continued to call us for available space.

Bottom Line Performance
As Whitestone entered 2007, the challenges mounted. Years of deferred property maintenance
and necessary capital improvements required immediate attention. Some marginal tenants
experienced business failures and had to be replaced. Attracting new tenants required
additional construction of space to accommodate their needs.

We dealt with these negative issues one by one. As a result of the investments in capital
improvements and property maintenance to attract better quality tenants that pay higher rents
with longer term leases, maintenance and leasing costs rose.

Legal costs of $2.2 million, or about $0.14 per share, were a major factor in reducing our
bottom line. We hope to have these legal issues resolved soon. With a trial date set for
May 19, 2008 (with an alternate date of June 2), and the favorable partial motion for summary
judgment we received in March 2008, we expect to put this distraction behind us.

We are pleased to report that the company is stable, our people in good spirits, our bank loans
in compliance, and our financial systems in place. In the past year, we have strengthened our
balance sheet and maintained our liquidity. We are positioned to grow the company, and when
the market timing is right, to list the company on a stock exchange for the public trading of
our shares.

We are confident about Whitestone’s future growth and proud of our achievements thus far.
On behalf of our board of trustees and entire management team, I thank our 1,700 investors
for the patience they have shown in supporting us through this year.

We appreciate your continued confidence and support.

Sincerely,

James C. Mastandrea
Chairman and Chief Executive Officer

•

•

•

•

•

changes in general economic conditions;

changes in real estate conditions;

construction costs that may exceed estimates;

Business.

General

PART I

We are a Maryland real estate investment trust (“REIT”) engaged in owning and operating income-
producing real properties. We invest in and operate retail, office and warehouse properties located in the
Houston, Dallas, San Antonio and Phoenix metropolitan areas.

We own a real estate portfolio of 37 properties containing approximately 3.1 million square feet of leasable
space, located in Texas and Arizona. The portfolio has a gross book value of approximately $182 million and
book equity, including minority interest, of approximately $81 million at December 31, 2007. We currently own
one property, located in Phoenix, Arizona, which is under development and is expected to be leasable by mid –
year 2008.

We were organized in December 2003 for the purpose of merging with Hartman Commercial Properties
REIT, a Texas real estate investment trust organized in August 1998. We are the surviving entity resulting from
the merger, which was consummated on July 28, 2004. We have elected to be taxed as a REIT trust under federal
income tax laws.

Our common shares are currently not traded on a stock exchange. Our offices are located at 2600 South
Gessner, Suite 500, Houston, Texas 77063. Our telephone number is (713) 827-9595 and we maintain an internet
site at www.whitestonereit.com.

Our Strategy

Our primary business objective is to increase shareholder value by employing a “value-add” strategy. We
seek well-located small properties in major cities that are income producing with renovation potential or other
upside potential, and add-value through our management and leasing expertise. The key elements of our strategy
include:

• Maximize value in current properties through operational focus and redevelopment.

• Grow through strategic acquisitions of commercial properties in high potential markets, including

properties outside of Texas.

•

•

Selectively dispose of properties that have little or no growth potential and reinvest the capital into
properties having potential for greater returns.

Pare down from three current product lines (retail, office and warehouse) and focus on one or possible
two product lines.

• Raise capital using a combination of the private and public equity and debt markets, as well as joint

ventures.

• Bring liquidity to our stock by listing on a national stock exchange.

We believe that our people are the heart of our company, our strategy and our structure. We are focused on
developing a team of people that display at all times a high degree of character and competence. We believe that
our people are key to our ability to generate long term shareholder value.

Our Structure

Substantially all of our business is conducted through Whitestone REIT Operating Partnership, L.P., a
Delaware limited partnership organized in 1998 (the “Operating Partnership”). We are the sole general partner of
the Operating Partnership. As of December 31, 2007, we owned a 62.4% interest in the Operating Partnership.

1

As of December 31, 2007, we owned a real estate portfolio consisting of 37 properties located in two states.
Leased to national, regional and local tenants, our retail, office and warehouse properties are primarily located
throughout Texas. As of December 31, 2007, the occupancy rate at our operating properties was 86.2% based on
leasable square footage compared to 83.3% as of December 31, 2006.

We invest in commercial properties with upside potential, where our leasing and operating strategies can
improve the existing properties’ value while providing superior current economic returns. We believe that
investment in and operation of commercial retail real estate is a local business and we focus our investments in
areas where we have strong knowledge of the local markets. The areas where a majority of our properties are
located are densely populated areas in and around Houston, Dallas, San Antonio and Phoenix. We plan to further
expand into markets outside of Texas and will continue to maintain our hands-on management philosophy. We
look for markets with strong demographic characteristics similar to that of Houston.

Our retail properties are primarily strip centers whose tenants consist of national, regional and local
retailers. Our properties generally attract tenants who provide basic staples and convenience items to local
customers. We believe sales of these items are less sensitive to fluctuations in the business cycle than higher
priced retail items. No single retail tenant represented more than 2.0% of total revenues for the year ended
December 31, 2007.

During 2007 we acquired one property, a 33,400 square ft garden office property located in Phoenix,
Arizona. This property was under development as of December 31, 2007. We take a very hands-on approach to
ownership, and directly manage the operations and leasing of our properties. Substantially all of our revenues
consist of base rents received under long-term leases. For the year ended December 31, 2007, our total revenues
were approximately $31.0 million. Approximately 72.2% of our existing leases contain “step up” rental clauses
that provide for increases in the base rental payments.

As of December 31, 2007, we have no assets that accounted for more that 10% of our year end consolidated
total assets. 33 of our 37 properties are located in the Houston, Texas metropolitan area. See “Location of
Properties” in Item 2 for further discussion regarding Houston’s economy.

Economic Factors

The national economy softened in 2007. The residential mortgage and capital markets began showing signs
of stress, primarily in the form of escalating default rates on sub-prime mortgages and declining residential
housing prices nationwide. This “credit crisis” spread to the broader commercial credit markets and has generally
reduced the availability of financing and widened spreads. These factors, coupled with a slowing economy, may
negatively impact the volume of real estate transactions and cap rates, which could negatively impact the value of
public real estate companies, including ours. While the housing market and energy prices may affect consumer
spending, the vast majority of our retail properties are located in densely populated metropolitan areas and are
anchored by supermarkets and discount stores, which generally provide basic necessity-type items and tend to be
less affected by economic changes. Furthermore, our portfolio is primarily positioned in metropolitan areas in
Texas which are forecasted to exceed the national average according to many economic measures. Our operating
areas continue to show strong employment growth as compared to other large metropolitan areas. However, if
these economic conditions persist in 2008 and beyond, our real estate portfolio may experience lower occupancy
and effective rents, which would result in a corresponding decrease in net income, funds from operations and
cash flows.

Competition

All of our properties are located in areas that include competing properties. The amount of competition in a
particular area could impact our ability to acquire additional real estate, sell current real estate, lease space and
the amount of rent we are able to charge. We may be competing with owners, including but not limited to, other
REITs, insurance companies and pension funds, with access to greater resources than those available to us.

Compliance with Governmental Regulations

Under various federal and state environmental laws and regulations, as an owner or operator of real estate,
we may be required to investigate and clean up certain hazardous or toxic substances, asbestos-containing
materials, or petroleum product releases at our properties. We may also be held liable to a governmental entity or
to third parties for property damage and for investigation and cleanup costs incurred by those parties in
connection with the contamination. In addition, some environmental laws create a lien on the contaminated site
in favor of the government for damages and costs it incurs in connection with the contamination. The presence of
contamination or the failure to remediate contaminations at any of our properties may adversely affect our ability
to sell or lease the properties or to borrow using the properties as collateral. We could also be liable under
common law to third parties for damages and injuries resulting from environmental contamination coming from
our properties.

We will not purchase any property unless and until we obtain what is generally referred to as a “Phase I”
environmental site assessment and are generally satisfied with the environmental status of the property. A Phase I
environmental site assessment basically consists of a visual survey of the building and the property in an attempt
to identify areas of potential environmental concerns, visually observing neighboring properties to assess surface
conditions or activities that may have an adverse environmental impact on the property, and contacting local
governmental agency personnel and performing a regulatory agency file search in an attempt to determine any
known environmental concerns in the immediate vicinity of the property. A Phase I environmental site
assessment does not generally include any sampling or testing of soil, groundwater or building materials from the
property. Certain properties that we have acquired contain, or contained, dry-cleaning establishments utilizing
solvents. Where believed to be warranted, samplings of building materials or subsurface investigations were
undertaken with respect to these and other properties. To date, the costs associated with these investigations and
any subsequent remedial measures taken have not been material to us.

We believe that our properties are in compliance in all material respects with all federal, state and local
ordinances and regulations regarding the handling, discharge and emission of hazardous or toxic substances. We
have not been notified by any governmental authority, and are not otherwise aware, of any material
noncompliance, liability or claim relating to hazardous or toxic substances in connection with any of our present
or former properties. We have not recorded in our financial statements any material liability in connection with
environmental matters. Nevertheless, it is possible that the environmental assessments we have obtained or
reviewed have not
is also possible that subsequent
environmental assessments or investigations will identify material contamination, that adverse environmental
conditions have arisen subsequent to the performance of the environmental assessments, or that there are material
environmental liabilities of which our management is unaware.

Item 1A. Risk Factors.

In addition to the other information contained in this Form 10-K the following risk factors should be
considered carefully in evaluating our business. Our business, financial condition, or results of operations could
be materially adversely affected by any of these risks. Please note additional risks not presently known to us or
which we currently consider immaterial may also impair our business and operations.

Risks Associated with Real Estate

Real estate property investments are illiquid, and therefore we may not be able to dispose of properties

when appropriate or on favorable terms.

Real estate property investments generally cannot be disposed of quickly. In addition, the federal tax code
imposes restrictions on the ability of a REIT to dispose of properties that are not applicable to other types of real
estate companies. Therefore, we may not be able to vary our portfolio in response to economic or other
conditions promptly or on favorable terms, which could cause us to incur extended losses and reduce our cash
flows and adversely affect distributions to shareholders.

Turmoil in capital markets could adversely impact acquisition activities and pricing of real estate assets.

Volatility in capital markets could adversely affect acquisition activities by impacting certain factors
including the tightening of underwriting standards by lenders and credit rating agencies and the significant
inventory of unsold collateralized mortgage backed securities in the market. These factors directly affect a
lender’s ability to provide debt financing as well as increase the cost of available debt financing. As a result, we
may not be able to obtain favorable debt financing in the future or at all. This may result in future acquisitions
generating lower overall economic returns, which may adversely affect our results of operations and distributions
to shareholders. Furthermore, any turmoil in the capital markets could adversely impact the overall amount of
capital available to invest in real estate, which may result in price or value decreases of real estate assets.

The value of investments in our common shares will be directly affected by general economic and

regulatory factors we cannot control or predict.

We only own commercial real estate. Investments in real estate typically involve a high level of risk as the
result of factors we cannot control or predict. One of the risks of investing in real estate is the possibility that our
properties will not generate income sufficient to meet operating expenses or will generate income and capital
appreciation, if any, at rates lower than those anticipated or available through investments in comparable real
estate or other investments. The following factors may affect
income from properties and yields from
investments in properties and are generally outside of our control:

•

•

•

•

•

•

conditions in financial markets;

over-building in our markets;

a reduction in rental income as the result of the inability to maintain occupancy levels;

adverse changes in applicable tax, real estate, environmental or zoning laws;

changes in general economic conditions;

a taking of any of our properties by eminent domain;

4

•

•

•

•

•

adverse local conditions (such as changes in real estate zoning laws that may reduce the desirability of
real estate in the area);

acts of God, such as earthquakes or floods and other uninsured losses;

changes in supply of or demand for similar or competing properties in an area;

changes in interest rates and availability of permanent mortgage funds, which may render the sale of a
property difficult or unattractive; and

periods of high interest rates and tight money supply.

Some or all of these factors may affect our properties, which could adversely affect our operations and

ability to pay dividends to shareholders.

Compliance or failure to comply with laws requiring access to our properties by disabled persons could

result in substantial cost.

The Americans with Disabilities Act (“ADA”) and other federal, state and local laws generally require
public accommodations be made accessible to disabled persons. Noncompliance could result in the imposition of
fines by the government or the award of damages to private litigants. These laws may require us to modify our
existing properties. These laws may also restrict renovations by requiring improved access to such buildings by
disabled persons or may require us to add other structural features which increase our construction costs.
Legislation or regulations adopted in the future may impose further burdens or restrictions on us with respect to
improved access by disabled persons. We may incur unanticipated expenses that may be material to our financial
condition or results of operations to comply with ADA and other federal, state and local laws, or in connection
with lawsuits brought by private litigants.

Competition could limit our ability to lease our properties or increase or maintain rental income.

There are numerous alternatives which compete with our properties in attracting tenants. Our properties
compete directly with other commercial properties which are available for rent or purchase in the markets in
which our properties are located. This competitive environment could have a material adverse effect on our
ability to lease our properties or any newly developed or acquired property, as well as on the rents charged.

Risks Associated with Our Operations

There can be no assurance that we will be able to pay or maintain cash dividends or that dividends will

increase over time.

There are many factors that can affect the availability and timing of cash dividends to shareholders.
Dividends will be based principally on cash available from our properties, real estate securities, mortgage loans
and other investments. The amount of cash available for dividends will be affected by many factors, such as our
ability to buy properties, the yields on securities of other real estate programs that we invest in, and our operating
expense levels, as well as many other variables. We can give no assurance that we will be able to pay or maintain
dividends or that dividends will increase over time. In addition, we can give no assurance that rents from the
properties will increase, that the securities we buy will increase in value or provide constant or increased
dividends over time, or that future acquisitions of real properties, mortgage loans or our investments in securities
will increase our cash available for dividends to shareholders. Our actual results may differ significantly from the
assumptions used by our Board in establishing the dividend rate to shareholders.

If we experience decreased cash flows, we may need to use other sources of cash to fund dividends or we

may be unable to pay dividends.

Actual cash available for dividends may vary substantially from estimates. If our cash dividends exceed the
amount of cash available for dividends, we may need to fund the shortage out of working capital, borrowings

5

under our lines of credit or by obtaining other debt, which would reduce the amount of proceeds available for real
estate investments. During the year ended December 31, 2007, our cash provided from operating activities was
$4.6 million and our total distributions were $9.5 million. Therefore we had distributions in excess of cash flow
for operations of approximately $4.9 million. Our primary funding for paying dividends in excess of cash flow
from operations was borrowing from our credit facility and the increase in the debt on our Windsor Park Centre
mortgage loan.

Because of the lack of geographic diversification of our portfolio, an economic downturn in the Texas

metropolitan areas could adversely impact our operations and ability to pay dividends to our shareholders.

The majority of our assets and revenues are currently derived from properties located in Texas metropolitan
areas. Our results of operations are directly contingent on our ability to attract financially sound commercial
tenants. If Texas experiences a significant economic downturn, our ability to locate and retain financially sound
tenants may be adversely impacted. Likewise, we may be required to lower our rental rates to attract desirable
tenants in such an environment. Consequently, because of the lack of geographic diversity among our current
assets,
if Texas experiences an economic downturn, our operations and ability to pay dividends to our
shareholders could be adversely impacted.

Our Properties have significant deferred maintanence which will affect our ability to lease the properties,

the types of tenants we are able to attract, and cash flow available for dividends

In 2007 we had property condition assessments (“PCA’s”) performed on 20 of our properties. The PCA’s
were performed as a result of the litigation with our former External Manager and were to determine the amount
of deferred maintanence that existed on the properties as of October 2006. The PCA’s indicated that
approximately $25 million in deferred maintanence existed on our properties as of October 2006. The majority of
these repairs relate to roofing ($10.3 million), parking lots ($3.6 million), structural ($3.3 million) and HVAC
($2.6 million). The significance of the deferred maintanence affects our ability to lease the vacant spaces and the
types of tenants we are able to attract. During 2007 we began to address these needed repairs and spent
approximately $1 million more on repairs than in 2006. Although we intend to judicially address the needed
repairs over the next several years, they will have a significant affect on our cash available to pay dividends.

Uninsured losses relating to real property or excessively expensive premiums for insurance coverage may

adversely affect our returns.

We will attempt to ensure that all of our properties are adequately insured to cover casualty losses.
However, there are types of losses, generally catastrophic in nature, such as losses due to wars, acts of terrorism,
earthquakes, floods, hurricanes, pollution or environmental matters, which are uninsurable or not economically
insurable, or may be insured subject to limitations, such as large deductibles or co-payments. Insurance risks
associated with potential terrorism acts could sharply increase the premiums we pay for coverage against
property and casualty claims. In some instances, we may be required to provide other financial support, either
through financial assurances or self-insurance, to cover potential losses. We cannot assure you that we will have
adequate coverage for these losses. In the event that any of our properties incurs a casualty loss that is not fully
covered by insurance, the value of our assets will be reduced by these uninsured losses. In addition, other than
any reserves we may establish, we have no source of funding to repair or reconstruct any uninsured damaged
property, and we cannot assure you that any sources of funding will be available to us for this purpose in the
future. Also, to the extent we must pay unexpectedly large insurance premiums, we could suffer reduced earnings
that would result in less cash dividends to be distributed to shareholders.

Discovery of previously undetected environmentally hazardous conditions may adversely affect our

operating results.

Under various federal, state and local environmental laws, ordinances and regulations, a current or previous
owner or operator of real property may be liable for the cost of removal or remediation of hazardous or toxic
substances on, under or in its property. The costs of removal or remediation could be substantial. These laws

6

often impose liability whether or not the owner or operator knew of, or was responsible for, the presence of any
hazardous or toxic substances. Environmental laws also may impose restrictions on the manner in which property
may be used or businesses may be operated, and these restrictions may require substantial expenditures.
Environmental laws provide for sanctions in the event of noncompliance and may be enforced by governmental
agencies or, in certain circumstances, by private parties. Certain environmental laws and common law principles
could be used to impose liability for release of and exposure to hazardous substances, including asbestos
containing materials into the air. In addition, third parties may seek recovery from owners or operators of real
properties for personal injury or property damage associated with exposure to released hazardous substances. The
cost of defending against claims of liability, of compliance with environmental regulatory requirements, of
remediating any contaminated property, or of paying personal injury claims could materially adversely affect our
business, assets or results of operations and, consequently, amounts available for payments of dividends to our
shareholders.

There is no public trading market for our shares of common stock, making it difficult for shareholders to

sell their shares.

There is no current public market for our common shares of beneficial interest. If you are able to find a
buyer for your shares, you may not sell your shares to that buyer unless the buyer meets the suitability standards
applicable to him or her, including any suitability standards imposed by the potential purchaser’s state of
residence. Our declaration of trust also imposes restrictions on the ownership of common shares that will apply to
potential transferees that may restrict your ability to sell your shares. In addition, our Board has delayed the
implementation of our share redemption program. Even if this program is implemented in the future, our Board
may reject any request for redemption of shares or amend, suspend or terminate the program at any time.
Therefore, it will be difficult for you to sell your shares promptly or at all. You may not be able to sell your
shares in the event of an emergency, and, if you are able to sell your shares, you may have to sell them at a
substantial discount.

We have acquired a majority of our properties, on a non “arms-length” basis, from entities controlled by

the previous advisor and CEO, Allen R. Hartman.

We acquired 27 of the 37 properties we owned as of December 31, 2007, from entities controlled by
Mr. Hartman. We acquired these properties by paying cash or issuing our commons shares of beneficial interest
or units of the Operating Partnership that are convertible into our common shares. No third parties were retained
to represent or advise these selling entities or us, and the transactions were not conducted on an “arm’s-length”
basis.

Mr. Hartman had interests that differed from, and in certain cases conflicted with, his co-investors in these

entities. Mr. Hartman received the following as a result of these transactions:

•

•

•

897,117.19 units of the Operating Partnership that are convertible into our common shares, as adjusted
to reflect the recapitalization, in consideration of Mr. Hartman’s general partner interest in the selling
entities;

the ability to limit his future exposure to general partner liability as a result of Mr. Hartman no longer
serving as the general partner to certain of the selling entities; and

the repayment of debt encumbering several of our properties that was personally guaranteed by
Mr. Hartman.

Mr. Hartman might not have been able to negotiate all of these benefits if the transactions were negotiated at
arm’s length. Further, Mr. Hartman did not make any representations or warranties in regard to the properties or
the selling entities (neither personally nor in his capacity as a general partner) in the documents evidencing the
transactions. Consequently, we essentially acquired the properties on an “as is” basis. Therefore, we will bear the
risk associated with any characteristics of or deficiencies in these properties unknown at the closing of the
acquisitions that may affect their valuation or revenue potential.

7

Approximately 38% of our gross leasable area is subject to leases that expire prior to December 31, 2010.

As of December 31, 2007, approximately 38% of the aggregate gross leasable area of our properties is

subject to leases that expire prior to December 31, 2010. We are subject to the risk that:

•

tenants may choose not to renew these leases;

• we may not be able to re-lease the space subject to these leases; and

•

the terms of any renewal or re-lease may be less favorable than the terms of the current leases.

If any of these risks materialize, our cash flow and ability to pay dividends could be adversely affected.

Litigation with Allen R. Hartman and Hartman Management.

We are currently involved in litigation with our former Chief Executive Officer, Allen R. Hartman, and
manager and advisor, Hartman Management, L.P. While we intend to vigorously defend against claims brought
by Mr. Hartman and Hartman Management and vigorously prosecute our claims against Mr. Hartman and
Hartman Management, there can be no assurances that we will ultimately prevail. Even if we do ultimately
prevail in these lawsuits, we may continue to incur significant legal costs to do so. For more discussion, see
Legal Proceedings and Management’s Discussion and Analysis of Financial Condition and Results of
Operations—Commitments and Contingencies.

Defending an adversarial shareholder campaign could be costly to shareholders, take managements

attention from day to day business operations and interfere with the execution of our strategic plan.

Our former Chief Executive Officer, Allen R. Hartman owns approximately 2.9% of the voting shares of the
REIT. If Mr. Hartman were to convert his ownership interests in the Operating Partnership into REIT common
shares, Mr. Hartman would own approximately 12.3% of the REIT’s voting shares. Mr. Hartman is also the
general partner of a partnership which owns 1.2 million OP Units which are convertible into REIT common
shares. Mr. Hartman has mounted an adversarial shareholder campaign with our shareholders and has attempted
to replace our current executive management and board of trustees. Defending this campaign could be costly to
shareholders, take management’s attention from day to day business operations and interfere with the execution
of our strategic plan.

Loss of our key personnel could adversely affect the value of our common shares of beneficial interest

and operations.

We are dependent on the efforts of our key executive personnel. Although we believe qualified
replacements could be found for these key executives, the loss of their services could adversely affect the value
of our common shares of beneficial interest and operations.

Risks Associated with Our Indebtedness and Financing

Our debt agreements impose limits on our operations and our ability to make distributions to our

shareholders.

The agreements relating to the debt we incur contain financial and operating covenants that may limit our
ability to make distributions or other payments to our shareholders. Our existing credit facilities contain financial
and operating covenants, including:

•

•

•

debt service coverage of at least 1.4 to 1.0;

loan-to-value ratio of a borrowing base pool to total funded loan balance of at least 1.67 to 1.00;

total debt not to exceed 60% of fair market value of our real estate assets;

8

•

•

the ratio of secured debt to fair market value of our real estate assets not to exceed 40%;

interest coverage ratio of at least 1.55 to 1.0;

• we must hedge certain amounts of variable interest rate debt;

• maintenance of specific levels of insurance; and

•

limitations on our ability to make distributions or other payments to our shareholders, sell assets or
engage in mergers, consolidation or make certain acquisitions.

Failure to comply with these covenants could result from, among other things, changes in our results of
operations, incurrence of debt or changes in general economic conditions. These covenants may restrict our
ability to fund our operations and conduct our business. Failure to comply with any of these covenants could
result in a default under our credit agreement or other debt agreements we may enter into in the future. A default
could cause one or more of our lenders to accelerate the timing of payments which could force us to dispose of
one or more of our properties, possibly on disadvantageous terms. For more discussion, see Management’s
Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources

We may incur losses on interest rate hedging arrangements.

Periodically, we have entered into agreements to reduce the risks associated with increases in interest rates,
and may continue to do so. Although these agreements may partially protect against rising interest rates, they
also may reduce the benefits to us if interest rates decline. If a hedging arrangement is not indexed to the same
rate as the indebtedness which is hedged, we may be exposed to losses to the extent which the rate governing the
indebtedness and the rate governing the hedging arrangement change independently of each other. Finally,
nonperformance by the other party to the hedging arrangement may subject us to increased credit risks.

We may incur mortgage indebtedness and other borrowings, which may increase our business risks.

If it is determined to be in our best interests, we may, in some instances, acquire real properties by using
either existing financing or borrowing new funds. In addition, we may incur or increase our current mortgage
debt to obtain funds to acquire additional real properties. We may also borrow funds if necessary to satisfy the
REIT distribution requirement described above, or otherwise as may be necessary or advisable to assure that we
maintain our qualification as a REIT for federal income tax purposes.

We may incur mortgage debt on a particular piece of real property if we believe the property’s projected
cash flow is sufficient to service the mortgage debt. If there is a shortfall in cash flow, however, the amount
available for dividends to shareholders may be affected. In addition, incurring mortgage debt increases the risk of
loss because defaults on such indebtedness may result in loss of property in foreclosure actions initiated by
lenders. For tax purposes, a foreclosure of any of our properties would be treated as a sale of the property for a
purchase price equal to the outstanding balance of the debt secured by the mortgage. If the outstanding balance of
the debt secured by the mortgage exceeds our tax basis in the property, we would recognize taxable income on
foreclosure, but would not receive any cash proceeds. We may give lenders full or partial guarantees for
mortgage debt incurred by the entities that own our properties. When we give a guaranty on behalf of an entity
that owns one of our properties, we will be responsible to the lender for satisfaction of the debt if it is not paid by
that entity. If any mortgages contain cross-collateralization or cross-default provisions, there is a risk that more
than one real property may be affected by a default. If any of our properties are foreclosed upon due to a default,
our ability to pay cash dividends to our shareholders will be adversely affected.

If we are unable to retain key personnel, our revolving credit facility could be in default and immediately

due.

In the event that James C. Mastandrea, for any reason, ceases to retain the title of Chief Executive Officer of
the Trust and to perform the functions typically performed under such office and to be actively involved in

9

strategic planning and decision-making for the Trust, unless within six months after such failure, the Board of
Directors or Board of Trustees has duly elected or appointed a qualified substitute to replace such individual who
is acceptable to our bank in its sole discretion, our bank may declare our loan in default and all amounts
immediately due.

In the event we have a change of control, our revolving credit facility could be in default and immediately

due.

If we have the occurrence of any transaction in which any “person” or “group” (within the meaning of
Section 13(d) and 14(d)(2) of the Securities Exchange Act of 1934) becomes the “beneficial owner” (as defined
in Rule 13d-3 under the Securities Exchange Act of 1934), directly or indirectly, of a sufficient number of voting
rights applicable to the Trust ordinarily entitled to vote in the election of directors or trustees, empowering such
“person” or “group” to elect a majority of the Board of Directors or Board of Trustees of the Trust, who did not
have such power before such transaction, our bank could declare our loan in default and all amounts immediately
due.

Risks Associated with Income Tax Laws

If we fail to qualify as a REIT, our operations and dividends to shareholders would be adversely

impacted.

We intend to continue to operate so as to qualify as a REIT under the Internal Revenue Code. A REIT
generally is not taxed at the corporate level on income it currently distributes to its shareholders. Qualification as
a REIT involves the application of highly technical and complex rules for which there are only limited judicial or
administrative interpretations. The determination of various factual matters and circumstances not entirely within
our control may affect our ability to continue to qualify as a REIT. In addition, new legislation, new regulations,
administrative interpretations or court decisions could significantly change the tax laws with respect
to
qualification as a REIT or the federal income tax consequences of qualification.

If we were to fail to qualify as a REIT in any taxable year:

• we would not be allowed to deduct our distributions to shareholders when computing our taxable

income;

• we would be subject to federal income tax (including any applicable alternative minimum tax) on our

taxable income at regular corporate rates;

• we would be disqualified from being taxed as a REIT for the four taxable years following the year

during which qualification was lost, unless entitled to relief under certain statutory provisions;

•

our cash available for dividends would be reduced and we would have less cash to pay dividends to
shareholders; and

• we may be required to borrow additional funds or sell some of our assets in order to pay corporate tax

obligations we may incur as a result of our disqualification.

We may need to incur additional borrowings to meet REIT minimum distribution requirements.

In order to maintain our qualification as a REIT, we are required to distribute to our shareholders at least
90% of our annual net taxable income (excluding any net capital gain). In addition, the Internal Revenue Code
will subject us to a 4% nondeductible excise tax on the amount, if any, by which certain distributions paid by us
with respect to any calendar year are less than the sum of (i) 85% of our ordinary income for that year, (ii) 95%
of our net capital gain for that year and (iii) 100% of our undistributed taxable income from prior years. Although
we intend to pay dividends to our shareholders in a manner that allows us to meet the distribution requirement
and avoid this 4% excise tax, we cannot assure you that we will always be able to do so.

10

Our income consists almost solely of our share of the Operating Partnership’s income, and the cash
available for distribution by us to our shareholders consists of our share of cash distributions made by the
Operating Partnership. Because we are the sole general partner of the Operating Partnership, our Board
determines the amount of any distributions made by it. Our Board may consider a number of factors in making
distributions, including:

•

•

•

•

the amount of the cash available for distribution;

the Operating Partnership’s financial condition;

the Operating Partnership’s capital expenditure requirements; and

our annual distribution requirements necessary to maintain our qualification as a REIT.

Differences in timing between the actual receipt of income and actual payment of deductible expenses and
the inclusion of income and deduction of expenses when determining our taxable income, as well as the effect of
nondeductible capital expenditures and the creation of reserves or required debt amortization payments could
require us to borrow funds on a short-term or long-term basis to meet the REIT distribution requirement and to
avoid the 4% excise tax described above. In these circumstances, we may need to borrow funds to avoid adverse
tax consequences even if our management believes that the then prevailing market conditions generally are not
favorable for borrowings or that borrowings would not be advisable in the absence of the tax consideration.

Changes in the tax law may adversely affect our REIT status

The discussions of the federal income tax considerations are based on current tax laws. Changes in the tax

laws could result in tax treatment that differs materially and adversely from that described herein.

Item 2.

Properties.

General

At December 31, 2007, we owned 37 commercial properties located in two states. We own 33 properties
located in the Houston, Texas, two properties located in Dallas, Texas, one property located in San Antonio,
Texas and one property in Phoenix, Arizona. Our properties consist of 19 retail centers with approximately
1,293,000 square feet of gross leasable area, 11 warehouse properties with approximately 1,202,000 square feet
of gross leasable area and seven office buildings with approximately 599,000 square feet of gross leasable area
and 33,000 square feet under development. We expect the Arizona property, which is under development, to be
leaseable by mid 2008. Each property is designed to meet the needs of surrounding local communities. As of
December 31, 2007, our properties contain approximately 3,093,000 square feet of gross leasable area. As of
December 31, 2007, our retail, warehouse and office properties were approximately 83.2%, 89.1% and 87.1%
leased, respectively.

As of December 31, 2007, we had one property that accounted for more than 10% of total gross revenue.
Uptown Tower is an office building located in Dallas, Texas that was acquired during 2005 and accounts for
11.4% of our total revenue and 9.7% of real estate assets, net of accumulated depreciation.

Location of Properties

Of our 37 properties, 36 are located in Texas, with 33 being located in the greater Houston metropolitan

statistical area. These 33 represent 78% of our rental income for the year ended December 31, 2007.

11

We believe that the Houston real estate market and economy are strong, boasting excellent long-term
growth prospects. The Houston workforce is concentrated in energy, chemicals,
information technology,
aerospace sciences and medical sciences. The Houston area ranked first in Texas for employment growth in
2006, with a growth rate of 4.1%. The most recent job growth data indicates that the Houston area gained
approximately 100,000 new jobs in 2007, ranking the metro area first in the country in job growth.

Houston Highlights

• Houston is the largest city in Texas and the 4th largest city in the U.S.

• Houston ranks 4th among U.S. metro areas in number of corporate headquarters for Fortune 500

companies.

• Houston is a key center for international finance with 21 foreign banks from 10 different nations.

• The Houston metro area’s population base grew by 797,700 people from 2000 to 2006, ranking the area

third in population growth during the period.

• The Houston metro area grew by 127,500 people during 2007.

Insurance

We believe that we have property and liability insurance with reputable, commercially rated companies. We
also believe that our insurance policies contain commercially reasonable deductibles and limits, adequate to
cover our properties. We expect to maintain this type of insurance coverage and to obtain similar coverage with
respect to any additional properties we acquire in the near future. Further, we have title insurance relating to our
properties in an aggregate amount that we believe to be adequate.

Regulations

Our properties, as well as any other properties that we may acquire in the future, are subject to various
federal, state and local laws, ordinances and regulations. They include, among other things, zoning regulations,
land use controls, environmental controls relating to air and water quality, noise pollution and indirect
environmental impacts such as increased motor vehicle activity. We believe that we have all permits and
approvals necessary under current law to operate our properties.

Item 3.

Legal Proceedings.

The nature of our business exposes us to the risk of lawsuits for damages or penalties relating to, among

other things, breach of contract and employment disputes. We are currently involved in the following litigation:

Hartman Commercial Properties REIT and Hartman REIT Operating Partnership, L.P. v. Allen R.

Hartman and Hartman Management, L.P., in the 333rd Judicial District Court of Harris County, Texas

In October 2006, we terminated our Chief Executive Officer, Allen R. Hartman, and our former manager
and advisor, Hartman Management, L.P. The same day, we filed this lawsuit seeking damages for breach of
contract, fraudulent inducement, and breach of fiduciary duties. Our new management approached Mr. Hartman
about cooperatively turning over operations of the company but Mr. Hartman ousted them from his offices. We
then sought an emergency court order requiring Mr. Hartman to turn over control to new management.
Mr. Hartman opposed this legal relief. The court issued an order requiring him to turn over control of the
company.

As part of the change from Mr. Hartman to new management, the company asked Mr. Hartman to agree to a
timeline for turning over specific operations and bank accounts. Mr. Hartman refused, so we had to file another

15

request with the court to require Mr. Hartman’s compliance. Only after we filed the request with the court did
Mr. Hartman relent and agree to a turnover timeline. During the turnover process, however, Mr. Hartman denied
the company access to its own books and records and we had to go back to court to enforce the previously
entered order that turned over the company to present management.

In November 2006, Mr. Hartman and Hartman Management filed a counterclaim against us, the individual
members of our Board, our Chief Operating Officer, John J. Dee, and our prior outside law firm and one of its
partners. The counterclaims claimed that we had breached our contracts with Mr. Hartman and Hartman
Managment and committed tortious interference with contract, intentional infliction of emotional distress, and
conspiracy. We prepared defenses to these counterclaims.

Subsequent to our preparations, Mr. Hartman and Hartman Management retained new attorneys. The new
attorneys filed amended counterclaims on behalf of Mr. Hartman and Hartman Management and dropped the
claims against the individual members of our Board, with the exception of our Chairman, James C. Mastandrea.
The amended counterclaims now also alleged negligence, fraud, and breach of fiduciary duty. We proceeded to
prepare defenses in response to these amended counterclaims.

Mr. Hartman then hired a different set of attorneys and amended the counterclaims again to drop all of the
claims against our prior outside law firm and its partner, many of the claims against us, and all of the claims,
without prejudice, against Mr. Mastandrea and Mr. Dee. The amended counterclaim now asserts claims against
us only for breach of contract and alleges that we owe Mr. Hartman and Hartman Management a fee for the
termination of an advisory agreement. In communications to shareholders, Mr. Hartman represented that the
termination fee, as calculated by him, could be in excess of $20 million.

We filed a motion for summary judgment on Mr. Hartman’s and Hartman Management’s claims that we
breached our contracts with Hartman Management. On March 25, 2008, the court granted our motion, in part,
and stated that the termination fee allegedly due under the advisory agreement was subject to the cap on total
operating expenses described in Section IV.D.1 of the North American Securities Administrators Association’s
Statement of Policy on Real Estate Investment Trusts.

The parties have each submitted reports of experts as to the amount of the fee due for the termination of the
advisory agreement, other fees and expense reimbursements, and damages. Discovery is being conducted for this
case, which has a court date of May 19, 2008. Before the court’s March 25, 2008 ruling that capped the advisory
agreement termination fee, Mr. Hartman and Hartman Management claimed damages of either $4.8 million or
$6.4 million plus prejudgment interest and attorneys’ fees; Whitestone maintains that no amounts are due for
fees, expenses and damages and we intend to vigorously defend against those claims and vigorously prosecute
our affirmative claims.

Hartman Commercial Properties REIT v. Allen R. Hartman, et al; in the United States District Court for

the Southern District of Texas

In November 2006, we learned that Mr. Hartman was soliciting written consents from shareholders and had
sought approval from the SEC to distribute a consent solicitation to replace our Board. We asked Mr. Hartman to
refrain from distributing the consent solicitation until the false and misleading information was removed. He
refused, so we initiated this lawsuit and sought a Temporary Injunction to stop Mr. Hartman from distributing the
consent solicitation.

Mr. Hartman and Hartman Management filed a counterclaim, alleging that certain changes to our bylaws
and declaration of trust were invalid and that their enactment was a breach of fiduciary duty. Mr. Hartman sought
a Temporary Injunction to prevent these changes from taking effect. These changes, among other things,
staggered the terms of our Board members over three years, required a two-thirds vote of the outstanding
common shares to remove a Board member and provided that our secretary may call a special meeting of
shareholders only on the written request of a majority of outstanding common shares.

16

With Mr. Hartman’s encouragement, a group of shareholders filed a motion to intervene and bring claims
against us in this lawsuit. The interveners’ claims were similar to the counterclaims filed by Mr. Hartman and
Hartman Management. The shareholders eventually dismissed their request to intervene with prejudice, though
not before we were required to prepare defenses to their claims and move to block their intervention.

The court ordered Mr. Hartman to refrain from distributing the consent solicitation while the parties
exchanged discovery and took depositions in preparation for a full hearing on the competing requests for
Temporary Injunctions. On April 6, 2007, the court ruled in our favor and Mr. Hartman was ordered not to
distribute the consent solicitation. Also on April 6, 2007, the court denied Mr. Hartman’s request for a
Temporary Injunction challenging the changes to our bylaws and declaration of trust and the court upheld the
changes to our bylaws and declaration of trust as valid exercises of the Board’s powers. The court also granted
our Motion to Dismiss, dismissing many of Mr. Hartman’s and Hartman Management’s remaining claims against
us.

Mr. Hartman appealed the court’s April 6, 2007 rulings to the Fifth Circuit Court of Appeals. After
considering the parties’ written briefs and oral arguments held in New Orleans, the Fifth Circuit upheld the lower
court’s rulings. We still have securities law claims against Mr. Hartman and Hartman Management and his
remaining counterclaims are still pending against us, though no monetary damages are being sought by either
side. Trial is currently set for November 2008.

Other

We are a participant in various other legal proceedings and claims that arise in the ordinary course of our
business. These matters are generally covered by insurance. While the resolution of these matters cannot be
predicted with certainty, we believe that the final outcome of these matters will not have a material effect on our
financial position, results of operations or cash flows.

PART II

Equity Securities.

Market Information

There is no established trading market for our common shares of beneficial interest. As of March 31, 2008,
we had 10,001,269 common shares of beneficial interest outstanding held by a total of approximately 1,423
shareholders.

Public Offering Proceeds

On September 15, 2004, our Registration Statement on Form S-11, with respect to our public offering of up
to 10,000,000 common shares of beneficial interest at a price of $10.00 per share, was declared effective under
the Securities Act of 1933. The Registration Statement also covers up to 1,000,000 shares available pursuant to
our dividend reinvestment plan to be offered at a price of $9.50 per share. The shares are offered to investors on a
best efforts basis. Post-Effective Amendments No. 1, 2 and 3 to the Registration Statement were declared
effective by the SEC on June 27, 2005, March 9, 2006 and May 3, 2006, respectively.

Our Board of Trustees terminated our public offering on October 2, 2006. Through December 31, 2007,
approximately 2.8 million shares had been issued pursuant to our public offering with gross offering proceeds
received of $28.3 million. An additional 165,000 shares had been issued pursuant to the dividend reinvestment
plan in lieu of dividends totaling $1.6 million. Shareholders that received shares pursuant to our dividend
reinvestment plan on or after October 2, 2006, may have recission rights as described in “Dividend Reinvestment
Plan” below.

The application of our gross offering proceeds from the offering are as follows (in thousands):

We initially used approximately $18.3 million and $7.9 million of our net proceeds from the offering to
repay our lines of credit and for working capital, respectively. We subsequently purchased real estate assets by
re-drawing on our lines of credit and using working capital. Therefore, the ultimate use of our net offering
proceeds was the acquisition of real estate assets.

Dividend Reinvestment Plan

Our dividend reinvestment plan allowed our shareholders to elect to have dividends from our common
shares reinvested in additional common shares. The purchase price per share under our dividend reinvestment
plan was $9.50. On March 27, 2007, we gave the required ten day notice to participants informing them that we

18

intend to terminate our dividend reinvestment plan. As a result, our dividend reinvestment plan terminated on
April 6, 2007. Shares issued under our dividend reinvestment plan were registered on our Registration Statement
on Form S-11. We did not amend or supplement our Registration Statement following our change in management
on October 2, 2006, and the events that occurred thereafter. As a result, shareholders that received approximately
64,000 shares issued under our dividend reinvestment plan on or after that date could be entitled to recission
rights. These rights would entitle these shareholders to recovery of their purchase price less any income received
on their shares.

Issuer Repurchases

We did not repurchase any of our equity securities during 2007. Our Board has approved (but delayed the
implementation of) a share redemption program that would enable shareholders to sell shares to us after holding
them for at least one year under limited circumstances. Our Board could choose to amend the provisions of the
share redemption program without shareholder approval. Our Board has chosen not to implement the share
redemption program at this time.

Dividends

In order to remain qualified as a REIT, we are required to distribute at least 90% of our annual taxable
income to our shareholders. We currently accrue dividends quarterly and pay dividends in three monthly
installments following the end of the quarter. We intend to continue paying dividends in this manner. For a
discussion of our cash flow as compared to dividends, see Management’s Discussion and Analysis of Financial
Condition and Results of Operations—Liquidity and Capital Resources.

The following table reflects the total dividends we have paid (including the total amount paid and the
amount paid per share) in each indicated quarter. The amounts provided give effect to our reorganization as a
Maryland real estate investment trust and the concurrent recapitalization of our common shares on July 28, 2004.

The dividends per share represent total cash payments divided by weighted average common shares.

(3) We believe that Funds From Operations (“FFO”) is an appropriate supplemental measure of operating
performance because it helps our investors compare our operating performance relative to other REITs. The
National Association of Real Estate Investment Trusts (“NAREIT”) defines FFO as net income (loss)
available to common shareholders computed in accordance with GAAP, excluding gains or losses from
sales of operating properties and extraordinary items, plus depreciation and amortization of real estate
assets, including our share of unconsolidated partnerships and joint ventures. We calculate FFO in a manner
consistent with the NAREIT definition.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion of our financial condition and results of operations in conjunction
with our audited consolidated financial statements and the notes thereto included in this annual report. For more
detailed information regarding the basis of presentation for the following information, you should read the notes
to our audited consolidated financial statements included in this annual report.

Overview

We are a real estate investment trust (“REIT”) engaged in owning and operating income-producing real
properties. Our investments include retail, office and warehouse properties located in the Houston, Dallas, San
Antonio and Phoenix metropolitan areas. Our properties consist of:

•

•

•

19 retail properties containing approximately 1.3 million square feet of leasable space and having a
total carrying amount (net of accumulated depreciation) of $67.0 million.

Six office properties containing approximately 0.6 million square feet of leasable space and having a
total carrying amount (net of accumulated depreciation) of $36.2 million.

11 office/warehouse properties containing approximately 1.2 million square feet of leasable space and
having a total carrying amount (net of accumulated depreciation) of $42.8 million.

• One office property under development having a total carrying amount of $8.4 million, which will

contain approximately 0.03 million square feet of leasable space upon completion.

Our primary source of income and cash is rents associated with commercial leases. Our business objective is
to increase shareholder value by employing a value-add investment strategy. This strategy is focused on owning
real estate assets in markets with positive demographic trends, achieving
and renovating commercial
diversification by property type and location, and acquiring properties within our targeted returns.

As of December 31, 2007, we had 720 total tenants. We have a diversified tenant base with our largest
tenant compromising only 1.8% of our total revenues for 2007. Lease terms for our properties range from less
than one year for smaller tenants to over 15 years for larger tenants. Our leases generally include minimum
monthly lease payments and tenant reimbursements for payment of taxes, insurance and maintenance.

We are a self-managed REIT, employing 46 full-time employees as of December 31, 2007. As a self-
managed REIT, we bear our own expenses of operations, including the salaries, benefits and other compensation
of our employees, office expenses, legal, accounting and investor relations expenses and other overhead.

Prior to November 14, 2006, our properties and day-to-day operations were externally managed by Hartman
Management, LP (“the External Manager”) under an advisory agreement and a management agreement. Under
this arrangement we were charged fees based on percentages of gross revenues, asset values, capital raised, and
expenses submitted for reimbursement. Our advisory agreement expired at the end of September 2006 and our
Board terminated our property management agreement in October 2006. The External Manager turned over all
property management functions to us on November 14, 2006.

We believe that one of the most key measures of our performance is property occupancy. Occupancy for the
total portfolio was 86.2% at December 31, 2007, compared to 83.3% at December 31, 2006. We completed 256
new and renewal leases during 2007 totaling 0.9 million square feet and $42.0 million in total lease value.

In the fourth quarter of 2006, our Board approved our five year business plan. The key elements of the plan

are as follows:

• Maximize value in current properties through operational focus and redevelopment

21

• Grow through strategic acquisitions of commercial properties in high potential markets, including

properties outside of Texas

• Dispose of non-core properties and reinvest the capital in redevelopment of existing properties or

acquisition of core properties in high potential markets

•

Pare down from three current product lines (retail, office and warehouse) and focus on one or possible
two product lines.

• Raise capital using a combination of the private and public equity and debt markets, as well as joint

ventures

• Bring liquidity to our stock by listing on a national stock exchange

During 2007, we have begun progress on the execution of this five year plan as described in the following

sections on redevelopment, acquisitions and dispositions.

Redevelopment

We began redevelopment in late 2007 to add 5,000 square feet of office space and upgrade the Westchase
Plaza Retail and Office Center located in Houston, Texas. The total redevelopment of this center is projected to
cost approximately $1.7 million and be completed by late 2008.

Acquisitions

In October of 2007, we acquired a 33,400 square foot commercial property in Carefree, Arizona which is
adjacent to North Scottsdale, for approximately $8.3 million. The property, Pima Norte, is a newly constructed
one and two story class “A” executive medical office building. The property is currently under development and
is expected to be leasable by mid 2008. We expect to invest approximately $2.0 million to complete the
construction.

Dispositions

On July 26, 2007, we sold a 2.4 acre parcel of vacant land next to our South Shaver retail property located in

Houston, Texas for a sales price of $0.3 million.

On December 1, 2006, we sold Northwest Place II, a 27,974 square foot office/warehouse building located

in Houston, Texas for a sales price of $1.2 million.

Summary of Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based on our
consolidated financial statements. We prepared these financial statements in conformity with U.S. generally
accepted accounting principles. The preparation of these financial statements required us to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and
the reported amounts of revenues and expenses during the reporting periods. We based our estimates on
historical experience and on various other assumptions we believe to be reasonable under the circumstances. Our
results may differ from these estimates. Currently, we believe that our accounting policies do not require us to
make estimates using assumptions about matters that are highly uncertain. You should read Note 2, Summary of
Significant Accounting Policies, to our consolidated financial statements in conjunction with this Management’s
Discussion and Analysis of Financial Condition and Results of Operations.

22

We have described below the critical accounting policies that we believe could impact our consolidated

financial statements most significantly.

Revenue Recognition. All leases on our properties are classified as operating leases, and the related rental
income is recognized on a straight-line basis over the terms of the related leases. Differences between rental
income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to
accrued rent and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon
which they are based have been met. Recoveries from tenants for taxes, insurance, and other operating expenses
are recognized as revenues in the period the corresponding costs are incurred. We have established an allowance
for doubtful accounts against the portion of tenant accounts receivable which is estimated to be uncollectible.

Development Properties. Land, buildings and improvements are recorded at cost. Expenditures related to the
development of real estate are carried at cost which includes capitalized carrying charges, acquisition costs and
development costs. Carrying charges, primarily interest, real estate taxes and loan acquisition costs, and direct
and indirect development costs related to buildings under construction, are capitalized as part of construction in
progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available
for occupancy. The Company capitalizes acquisition costs once the acquisition of the property becomes probable.
Prior to that time, we expense these costs as acquisition expense. During the year ended December 31, 2007,
interest in the amount of $0.1 was capitalized on properties under development. No such amounts were
capitalized in 2006 or 2005.

Acquired Properties and Acquired Lease Intangibles. We account for real estate acquisitions pursuant to
Statement of Financial Accounting Standards (“SFAS”) No. 141, Business Combinations. Accordingly, we
allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible
assets and to the acquired liabilities based on their respective fair values. Identifiable intangibles include amounts
allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any.
We determine fair value based on estimated cash flow projections that utilize appropriate discount and
capitalization rates and available market information. Estimates of future cash flows are based on a number of
factors including the historical operating results, known trends and specific market and economic conditions that
may affect the property. Factors considered by management in our analysis of determining the as-if-vacant
property value include an estimate of carrying costs during the expected lease-up periods considering market
conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate
taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand
and other economic conditions. Management also estimates costs to execute similar leases including leasing
commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases
and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental
revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or
discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.

Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of
five to 39 years for the buildings and improvements. Tenant improvements are depreciated using the straight-line
method over the life of the lease.

Impairment. We review our properties for impairment annually or whenever events or changes in
circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be
recoverable through operations. We determine whether an impairment in value has occurred by comparing the
estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of
the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the
amount by which the carrying value of the property exceeds its fair value. Management has determined that there
has been no impairment in the carrying value of our real estate assets as of December 31, 2007.

23

Accrued Rent and Accounts Receivable. Included in accrued rent and accounts receivable are base rents,
tenant reimbursements and receivables attributable to recording rents on a straight-line basis. An allowance for
the uncollectible portion of accrued rents and accounts receivable is determined based upon customer credit-
worthiness (including expected recovery of our claim with respect to any tenants in bankruptcy), historical bad
debt levels, and current economic trends. As of December 31, 2007 and 2006, we had an allowance for
uncollectible accounts of $1.1 million and $0.6 million, respectively. During 2007, 2006 and 2005, we recorded
bad debt expense in the amount of $0.6 million, $0.4 million and $0.1 million, respectively, related to tenant
receivables that we specifically identified as potentially uncollectible based on our assessment of each tenant’s
credit-worthiness. Bad debt expenses and any related recoveries are included in property operation and
maintenance expense.

Unamortized Lease Commissions and Loan Costs. Leasing commissions are amortized using the straight-
line method over the terms of the related lease agreements. Loan costs are amortized on the straight-line method
over the terms of the loans, which approximates the interest method. Costs allocated to in-place leases whose
terms differ from market terms related to acquired properties are amortized over the remaining life of the
respective leases.

Federal Income Taxes. We are qualified as a real estate investment trust under the Internal Revenue Code of
1986 and are therefore not subject to Federal income taxes provided we meet all conditions specified by the
Internal Revenue Code for retaining our REIT status. We believe we have continuously met these conditions
since reaching 100 shareholders in 1999 (see Note 11 to the consolidated financial statements).

Derivative Instruments. We have initiated a program designed to manage exposure to interest rate
fluctuations by entering into financial derivative instruments. The primary objective of this program is to comply
with debt covenants on a credit facility. We have entered into an interest rate swap agreement with respect to
amounts borrowed under certain of our credit facilities, which effectively exchanges existing obligations to pay
interest based on floating rates for obligations to pay interest based on fixed LIBOR rates.

We have adopted SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as
subsequently amended by SFAS No. 138, “Accounting for Certain Derivative Instruments and Certain Hedging
Activities,” and SFAS No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging
Activities,” which require for items appropriately classified as cash flow hedges that changes in the market value
of the instrument and in the market value of the hedged item be recorded as other comprehensive income with
the exception of the portion of the hedged items that are considered ineffective. The derivative instruments are
reported at fair value as other assets or other liabilities as applicable. As of December 31, 2007, we have a $70.0
million dollar interest rate swap which has been designated as a cash flow hedge. The fair value of this interest
rate swap is approximately ($0.4) million and is included in accounts payable and accrued expenses in the
consolidated balance sheet. Additionally, for a previous interest rate swap which was not designated as a cash
flow hedge, approximately ($0.03) million and $0.03 million are included in other expense and other income on
the consolidated statement of income for the year ended December 31, 2007 and 2006, respectively.

New Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48
(“FIN 48”), “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109.” FIN
48 clarifies the accounting for uncertainty in income taxes recognized in the financial statements. The
interpretation prescribes a recognition threshold and measurement attribute for
the financial statement
recognition of a tax position taken, or expected to be taken, in a tax return. A tax position may only be
recognized in the financial statements if it is more likely than not that the tax position will be sustained upon
examination. There are also several disclosure requirements. We adopted this interpretation during the first
quarter of 2007, and it had no effect on our consolidated financial statements.

24

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157
defines fair value, establishes a framework for measuring fair value under U.S. generally accepted accounting
principles and requires enhanced disclosures about fair value measurements. It does not require any new fair
value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. We do not expect this pronouncement to have
a material effect on our consolidated results of operation or financial position.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS 159”). SFAS 159 permits
entities to choose to measure many financial instruments and certain other items at fair value. The objective is to
improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings
caused by measuring related assets and liabilities differently without having to apply complex hedge accounting
provisions. SFAS 159 is effective for financial statements issued for fiscal years beginning after November 15,
2007 and interim periods within those fiscal years. We currently do not plan to measure any eligible financial
assets and liabilities at fair value under the provisions of SFAS No. 159.

In September 2007, the FASB ratified Emerging Issues Task Force (“EITF”) Issue 07-6, “Accounting for the
Sale of Real Estate Subject to the Requirements of FASB Statement No. 66 When the Agreement Includes a
Buy-Sell Clause,” which clarifies that a buy-sell clause, in and of itself, does not constitute a prohibited form of
continuing involvement that would preclude partial sale treatment under Statement 66. EITF 07-6 applies
prospectively to new arrangements entered into in fiscal years beginning after December 15, 2007.

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations,” which replaces SFAS
No. 141, “ Business Combinations,” which, among other things, establishes principles and requirements for how
an acquirer entity recognizes and measures in its financial statements the identifiable assets acquired, the
liabilities assumed (including intangibles) and any noncontrolling interests in the acquired entity. SFAS
No. 141(R) applies prospectively to business combinations for which the acquisition date is on or after the
beginning of the first annual reporting period beginning on or after December 15, 2008.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial
Statements, an amendment of ARB No. 51.” SFAS No. 160 amends ARB 51 to establish accounting and reporting
standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It also
amends certain of ARB 51’s consolidation procedures for consistency with the requirements of SFAS
No. 141(R). SFAS No. 160 is effective for fiscal years, and interim periods within those fiscal years, beginning
on or after December 15, 2008. We are currently evaluating what impact our adoption of SFAS No. 160 will
have on our financial statements.

Liquidity and Capital Resources

Our primary liquidity demands are distributions to the holders of our common shares and holders of units of
limited partnership interest in the Operating Partnership (“OP Units”), capital improvements and repairs and
maintenance for our properties, acquisition of additional properties, tenant improvements and debt repayments.

Primary sources of capital for funding our acquisitions and redevelopment programs are our $75 million
revolving credit facility, cash generated from sales of properties that no longer meet investment criteria, cash
flow generated from operating activities and bank debt.

Our capital structure also includes non-recourse secured debt that we assumed or originated on certain
properties. We hedge the future cash flows of certain debt transactions principally through interest rate swaps
with major financial institutions.

25

During the year ended December 31, 2007, our cash provided from operating activities was $4.6 million and
our total distributions were $9.5 million. Therefore we had distributions in excess of cash flow from operations
of approximately $4.9 million. Our primary funding for paying dividends in excess of cash flow from operations
was borrowing from our credit facility and the increase in the debt on our Windsor Park Centre mortgage loan.

During the year ended December 31, 2007, we incurred approximately $2.2 million in legal costs as a result
of the ongoing litigation with Mr. Hartman and Hartman Management, LP. For a full discussion of the litigation
with Mr. Hartman and Hartman Management see Item 3 – Legal Proceedings. We do not know when this
litigation will be fully resolved. The continued legal cost associated with this litigation may have a significant
impact on our cash flow. We anticipate that cash flows from operating activities and our borrowing capacity will
provide adequate capital for our working capital requirements, anticipated capital expenditures, litigation costs
and scheduled debt payments during the next 12 months. We also believe that cash flows from operating
activities and our borrowing capacity will allow us to make all distributions required for us to continue to qualify
to be taxed as a REIT.

Cash and Cash Equivalents

We had cash and cash equivalents of $10.8 million at December 31, 2007, as compared to $8.3 million on

December 31, 2006. The increase of $2.5 million was primarily the result of the following:

Sources of Cash

• Cash flow from operations of $4.6 million for the year ended December 31, 2007.

• Net proceeds of $17.1 million from our credit facility and refinancing of our Windsor Park Centre

property.

• Repayment of note receivable of $0.6 million. We originally issued this note receivable in 2003 in

conjunction with the sale of a property.

Uses of Cash

•

Payment of dividends and distributions to common shareholders and OP Unit holders of $9.5 million.

• Additions to real estate of $10.2 million.

We place all cash in short-term, highly liquid investments that we believe provide appropriate safety of

principal.

Debt

As of December 31, 2007, we had two active loans:

Revolving Credit Facility

We have a revolving credit facility with a consortium of banks. The credit facility is secured by a pledge of
the partnership interests in Whitestone REIT Operating Partnership III, L.P. (“WROP III”), a wholly owned
subsidiary of the Operating Partnership that was formed to hold title to the properties comprising the borrowing
base pool for the facility. At December 31, 2007, WROP III owned 35 properties.

As of December 31, 2007 and December 31, 2006, the balance outstanding under the credit facility was
$73.5 million and $61.2 million, respectively, and the availability to draw was $1.5 million and $13.8 million,
respectively.

26

Mortgage Loan on Windsor Park Centre

On March 1, 2007, we obtained a $10.0 million loan to pay off the loan obtained upon the acquisition of the
Windsor Park property and to provide funds for future acquisitions. The mortgage loan is secured by the Windsor
Park property which is owned by Whitestone REIT Operating Company IV, LLC (“WROC IV”), a wholly
owned subsidiary of the Operating Partnership that was formed to hold title to the Windsor Park property. On
March 1, 2007, we conveyed ownership of the Windsor Park property from the Operating Partnership to WROC
IV in order to secure the $10.0 million mortgage loan.

The note is payable in equal monthly installments of principal and interest of $60,212, with interest at the
rate of 6.04% per annum. The balance of the note is payable in full on March 1, 2014. The loan balance is
approximately $9.9 million at December 31, 2007.

For further discussion regarding specific terms of our debt, see Note 9 of the Consolidated Financial

Statements.

Capital Expenditures

We continually evaluate our properties performance and value. We may determine it is best to invest capital
in properties we believe have potential for increasing value. We also may have unexpected capital expenditures
or improvements for our existing assets. Additionally, we intend to invest in similar properties outside of Texas
in cities with exceptional demographics to diversify market risk, and we may incur significant capital
expenditures or make improvements in connection with any properties we may acquire.

Contractual Obligations

As of December 31, 2007, we had the following contractual debt obligations (see Note 9 of the Consolidated

Revenues

Substantially all of our revenue is derived from rents received from leases at our properties. We had rental
income and tenant reimbursements of approximately $31.0 million for the year ended December 31, 2007, as
compared to $29.8 million for the year ended December 31, 2006, an increase of $1.2 million or 4%. Our year
end occupancy rate in 2007 was 86%, as compared to 83% at year end 2006. The majority of the increase in
occupancy occurred near the end of the year in 2007 and did not have a material impact on revenue in 2007. We
expect revenue to increase in 2008 as a result of this increase in occupancy. Our average gross leaseable area was
approximately 3,093,000 in 2007 versus 3,127,000 in 2006. Our average annualized revenue was $10.02 per
square foot in 2007, as compared to our average annualized revenue of $9.56 per square foot in 2006.

Operating Expenses

Our total operating expenses were $26.0 million for the year ended December 31, 2007, as compared to
$22.3 million for the year ended December 31, 2006, an increase of $3.7 million, or 16.6%. The primary
components of total operating expense are detailed in the table below (in thousands):

Property operation and maintenance

The increase in property operation and maintenance expenses for the year ended December 31, 2007, as
compared to the year ended December 31, 2006, is primarily the result of increased repair and maintenance costs
for our properties. The majority of these costs relate to work that had been deferred prior to our managing our
own properties. While these costs decreased our earnings for the year ended December 31, 2007, we believe that
they will ultimately result in higher tenant satisfaction, lower tenant attrition and higher occupancy levels.

Property management and asset management fees paid to an affiliate

On September 30, 2006, our advisory agreement with our External Manager expired. On November 14,
2006, all property management functions were transferred to us from our external manager. As such, no external
management fees were charged after November 13, 2006.

General and Administrative Expense

Prior to October 2, 2006, we were externally managed, which makes a comparison of costs difficult given
the different nature of the expenses incurred by an externally-managed REIT versus an internally-managed one.
As an externally-managed REIT, we were charged fees based on percentages of gross revenues, asset values,
capital raised, and expenses submitted for reimbursement. Generally accepted accounting principles allowed for
many of theses fees to be capitalized as an asset or accounted for as a reduction in equity.

Subsequent to October 2, 2006, we operated as an internally-managed REIT and many of the costs that were
previously capitalized or recorded as a reduction in equity are now charged to general and administrative expense
and reflected in the Consolidated Statement of Operations.

29

During the years ended December 31, 2007 and 2006, we executed new and renewal leases with a total lease
value of $42.0 million and $20.0 million, respectively. Prior to October 2, 2006 we paid our former management
company 6.0% of the total value of new leases and 4.0% of the total value of renewal leases. If we had executed
the same volume of leases in 2006, we estimate that we would have paid an additional $1.1 million in leasing
commission cost to our External Manager in 2006. Additionally, significant legal expense has been incurred in
2007 related to the ongoing litigation with our former External Manager. For a detailed discussion of the
litigation, please refer to Item 3, Legal Proceedings.

The chart below is a comparison of the total costs incurred for general and administrative services in the
years ended December 31, 2007 and 2006. In order to be a meaningful comparison, the chart contains a pro
forma adjustment to 2006 to show the increased lease commission cost assuming the same volume of leasing
activity as 2007. Excluding legal costs related to the litigation with our former External Manager and adjusting
for the incremental leasing commission that would have been paid in 2006, costs for general and administrative
services in 2007 were slightly lower than in 2006.

In order to be comparable, a pro forma adjustment is made to the 2006 lease fees to relect the additional fees
that would have been paid to the former management company if they had executed the same volume of
leases, as defined by total lease value, in 2006 as we executed in 2007 with our internal leasing staff.

Litigation cost represent fees paid as a result of our litigation with Allen R. Hartman and Hartman
Managment L.P. For further discussion regarding our ongoing litigation please refer to Item 3. Legal
Proceedings.

Operating Income

Operating income was $5.0 million for the year ended December 31, 2007, as compared to $7.5 million for
the year ended December 31, 2006, a decrease of $2.5 million or 33%. The primary reasons for the decrease are
detailed above in Revenues and Operating Expenses.

30

Other Income (Expense)

Other expense increased by $0.4 million primarily as a result of the Texas Margin Tax which was enacted in

2007.

Net Income (Loss)

Income before minority interest was a loss of ($0.1) million for the year ended December 31, 2007, as
compared to $2.8 million for the year ended December 31, 2006, a decrease of $2.9 million. Net income for the
year ended December 31, 2007, was a loss of ($0.08) million, as compared to $1.8 million for the year ended
December 31, 2006, a decrease of $1.9 million. These decreases are a result of the items discussed above.

Revenues

Substantially all of our revenue is derived from rents received for leases at our properties. We had rental
income and tenant reimbursements of approximately $29.8 million for the year ended December 31, 2006, as
compared to $24.9 million for the year ended December 31, 2005, an increase of $4.9 million or 20%. Of this
increase, $4.4 million or 90% was from receiving a full year of revenue on the three properties acquired during
2005. The remaining increase resulted from an increase in rental rates charged. Our average occupancy rate in
2006 was 83%, as compared to 84% in 2005, and our average annualized revenue was $9.56 per square foot in
2006, as compared to our average annualized revenue of $8.91 per square foot in 2005.

Operating Expenses

Our total operating expenses were $22.3 million for the year ended December 31, 2006, as compared to
$17.1 million for the year ended December 31, 2005, an increase of $5.2 million, or 30%. Of this increase, $2.9

Properties acquired in 2005

During 2005, we acquired from unrelated parties three multi-tenant office buildings comprising
approximately 0.4 million square feet of gross leasable area. The properties were acquired for cash for
approximately $30.8 million. As these properties were acquired during the year, only a partial year of operating
expense is included in 2005. The increase is primarily a result of a full year of operating expense in 2006
compared to a partial year in 2005.

Real Estate Taxes

The increase in taxes of $0.2 million is primarily a result of an approximate 8% increase in overall property

values by local appraisal districts.

Property management and asset management fees paid to an affiliate

On September 30, 2006, our advisory agreement with the External Manager expired. On November 14,
2006, all property management functions were transferred to us from the External Manager. As such, no fees
were paid to the External Manager after November 13, 2006. The property management and asset management
fees paid to by the External Manager through November 13, 2006 and September 30, 2006, respectively, were
$0.3 million or 24% higher than the same period in 2005.

General and Administrative

The increase in our general and administrative expenses of $1.2 million is primarily due to legal fees
incurred in the fourth quarter of 2006 resulting from the termination of the management and advisory
agreements, the termination of Mr. Hartman as our President, Secretary and Chief Executive Officer and the
litigation with Mr. Hartman and Hartman Management.

Operating Income

Operating income was $7.5 million for the year ended December 31, 2006, as compared to $7.8 million for
the year ended December 31, 2005, a decrease of $0.3 million or 4%. The primary reasons for the decrease are
detailed above in Revenues and Operating Expenses.

32

Other Income (Expense)

Other expense was $4.7 million for the year ended December 31, 2006, as compared to $3.5 million for the
year ended December 31, 2005, an increase of $1.2 million or 34%. The primary reason for the increase was a
$1.5 million increase in interest expense as a result of higher variable interest rates in 2006, as compared to 2005,
offset by a gain of $0.2 million recorded in 2006 from the sale of Northwest Place II.

Net Income

Income before minority interest was $2.8 million for the year ended December 31, 2006, as compared to
$4.3 million for the year ended December 31, 2005, a decrease of $1.5 million or 35%. Net income for the year
ended December 31, 2006, was $1.8 million, as compared to $2.4 million for the year ended December 31, 2005,
a decrease of $0.6 million, or 25%. These decreases are a result of the items discussed above.

Funds From Operations

The National Association of Real Estate Investment Trusts defines funds from operations (“FFO”) as net
income (loss) available to common shareholders computed in accordance with generally accepted accounting
principles (“GAAP”), excluding gains or losses from sales of operating real estate assets and extraordinary items,
plus depreciation and amortization of operating properties, including our share of unconsolidated real estate joint
ventures and partnerships. We calculate FFO in a manner consistent with the NAREIT definition.

Management uses FFO as a supplemental measure to conduct and evaluate our business because there are
certain limitations associated with using GAAP net income by itself as the primary measure of our operating
performance. Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that
the value of real estate assets diminishes predictably over time. Since real estate values instead have historically
risen or fallen with market conditions, management believes that the presentation of operating results for real
estate companies that uses historical cost accounting is insufficient by itself. There can be no assurance that FFO
presented by us is comparable to similarly titled measures of other REITs.

FFO should not be considered as an alternative to net income or other measurements under GAAP as an
indicator of our operating performance or to cash flows from operating, investing or financing activities as a
measure of liquidity. FFO does not reflect working capital changes, cash expenditures for capital improvements
or principal payments on indebtedness.

Below is the calculation of FFO and the reconciliation to net income, which we believe is the most

comparable GAAP financial measure (in thousands):

Taxes

We elected to be taxed as a REIT under the Internal Revenue Code beginning with our taxable year ended
December 31, 1999. As a REIT, we generally are not subject to federal income tax on income that we distribute
to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax

33

on our taxable income at regular corporate rates. We believe that we are organized and operate in such a manner
as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal
income tax purposes.

Inflation

We anticipate that the majority of our leases will continue to be triple-net leases or otherwise provide that
tenants pay for increases in operating expenses and will contain provisions that we believe will mitigate the
effect of inflation. In addition, many of our leases are for terms of less than five years, which allows us to adjust
rental rates to reflect inflation and other changing market conditions when the leases expire. Consequently,
increases due to inflation, as well as ad valorem tax rate increases, generally do not have a significant adverse
effect upon our operating results.

Off-Balance Sheet Arrangements

We have no significant off-balance sheet arrangements as of December 31, 2007.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market risk is the risk of loss arising from adverse changes in market rates and prices. The principal market
risk to which we are exposed is the risk related to interest rate fluctuations. Based upon the nature of our
operations, we are not subject to foreign exchange or commodity risk. We will be exposed to changes in interest
rates as a result of our credit facilities that have floating interest rates. As of December 31, 2007, we had $3.5
million of indebtedness outstanding under facilities with floating interest rates. The impact of a 1% increase in
interest rates on our debt would result in an increase in interest expense and a decrease in income before minority
interests of approximately $0.04 million annually.

Item 9T. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

In connection with the preparation of this Form 10-K, as of December 31, 2007, an evaluation was
performed under the supervision and with the participation of the Company’s management, including the CEO
and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in
Rule 13a-15(e) under the Exchange Act. In performing this evaluation, management reviewed the selection,
application and monitoring of our historical accounting policies. Based on that evaluation, the CEO and CFO
concluded that
the
information required to be disclosed in our reports filed with the SEC is recorded, processed, summarized and
reported on a timely basis.

these disclosure controls and procedures were effective and designed to ensure that

During the audit of the year ended December 31, 2006, our independent registered public accounting firm
brought to management’s attention two material weaknesses in internal controls: (1) Inadequate controls and
procedures in place to effectively monitor and record non-routine transactions and (2) Inadequate controls and

34

procedures in place to effectively manage certain spreadsheets that support the financial reporting process. A
material weakness in internal control is a significant deficiency, or combination of significant deficiencies, that
results in more than a remote likelihood that a material misstatement of the financial statements would not be
prevented or detected on a timely basis by the Company. The Company implemented controls and procedures
designed to remediate these material weaknesses. These controls and procedures included the automation of
many of the processes that previously were performed in spreadsheets and further review of non-routine
transactions. Management has ensured that these new controls and procedures are operating effectively and fully
address the risks giving rise to the material weakness. Accordingly, management believes that these material
weaknesses have been fully remediated as of December 31, 2007.

Management’s Annual Report on Internal Control Over Financial Reporting and Attestation Report of

the Independent Registered Public Accounting Firm

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the
participation of our management, we conducted an evaluation of the effectiveness of our internal control over
financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in
Internal Control—Integrated Framework, our management concluded that our internal control over financial
reporting was effective as of December 31, 2007.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2007 is not
subject to attestation pursuant to temporary rules of the Securities and Exchange Commission that permit the
Company to provide only Management’s report and therefore has not been audited by our independent registered
public accounting firm.

Changes in Internal Control Over Financial Reporting

Except as discussed above,

there have been no other changes during the Company’s quarter ended
December 31, 2007, in the Company’s internal controls over financial reporting that have materially affected, or
are reasonably likely to materially affect, the Company’s internal controls over financing reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of
Whitestone REIT

We have audited the accompanying consolidated balance sheets of Whitestone REIT and subsidiary (the
“Company”) as of December 31, 2007 and 2006, and the related consolidated statements of operations and
comprehensive income (loss), shareholders’ equity and cash flows, for each of the three years in the period ended
December 31, 2007. In connection with our audits of the consolidated financial statements, we have also audited
the financial statement schedules as listed in the accompanying index. These consolidated financial statements
and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to
express an opinion on these financial statements and financial statement schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audits to obtain reasonable
assurance about whether the financial statements are free of material misstatement. The Company is not required
to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purposes of expressing an opinion on the effectiveness of the
Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, as well as evaluating
the overall financial 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
consolidated financial position of Whitestone REIT and subsidiary as of December 31, 2007 and 2006, and the
consolidated results of their operations and their cash flows for each of the three years in the period ended
December 31, 2007 in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the
related financial statement schedules, when considered in relation to the basic consolidated financial statements
taken as a whole, present fairly, in all material respects, the information set forth therein.

WHITESTONE REIT AND SUBSIDIARY

Notes to Consolidated Financial Statements

December 31, 2007

1. Description of Business and Nature of Operations

Whitestone REIT (“Whitestone”) was formed as a real estate investment trust, pursuant to the Texas Real
Estate Investment Trust Act on August 20, 1998. In July 2004, Whitestone changed its state of organization from
Texas to Maryland pursuant to a merger of Whitestone directly with and into a Maryland real estate investment trust
formed for the sole purpose of the reorganization and the conversion of each outstanding common share of
beneficial interest of the Texas entity into 1.42857 common shares of beneficial interest of the Maryland entity.
Whitestone serves as the general partner of Whitestone REIT Operating Partnership, L.P. (the “Operating
Partnership” or “WROP” or “OP”), formerly known as Hartman REIT Operating Partnership L.P., which was
formed on December 31, 1998 as a Delaware limited partnership. Whitestone currently conducts substantially all of
its operations and activities through the Operating Partnership. As the general partner of the Operating Partnership,
Whitestone has the exclusive power to manage and conduct the business of the Operating Partnership, subject to
certain customary exceptions. As of December 31, 2007, 2006 and 2005 we owned and operated 37, 36, and 37
retail, warehouse and office properties in and around Houston, Dallas, San Antonio and Phoenix.

2. Summary of Significant Accounting Policies

Basis of Consolidation

We are the sole general partner of the Operating Partnership and possess full legal control and authority
over the operations of the Operating Partnership. As of December 31, 2007, 2006 and 2005, we owned a majority
of the partnership interests in the Operating Partnership. Consequently, the accompanying consolidated financial
statements include the accounts of the Operating Partnership. All significant inter-company balances have been
eliminated. Minority interest in the accompanying consolidated financial statements represents the share of
equity and earnings of the Operating Partnership allocable to holders of partnership interests other than us. Net
income or loss is allocated to minority interests based on the weighted-average percentage ownership of the
Operating Partnership during the year. Issuance of additional common shares of beneficial interest in Whitestone
(“common shares”) and units of limited partnership interest in the Operating Partnership that are convertible into
common shares on a one for one basis (“OP Units”) changes the ownership interests of both the minority
interests and Whitestone.

Basis of Accounting

Our financial records are maintained on the accrual basis of accounting whereby revenues are recognized

when earned and expenses are recorded when incurred.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Significant estimates that we use include the estimated
useful lives for depreciable and amortizable assets and costs, the estimated allowance for doubtful accounts, and
the estimated fair value of interest rate swaps. Actual results could differ from those estimates.

Reclassifications

We have reclassified certain prior fiscal year amounts in the accompanying consolidated financial
statements in order to be consistent with the current fiscal year presentation. These reclassifications had no effect
on net income or shareholders’ equity.

December 31, 2007

2. Summary of Significant Accounting Policies (Continued)

Revenue Recognition

All leases on our properties are classified as operating leases, and the related rental income is recognized on
a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts
due per the respective lease agreements are capitalized or charged, as applicable, to accrued rent receivable.
Percentage rents are recognized as rental income when the thresholds upon which they are based have been met.
Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the
period the corresponding costs are incurred. We have established an allowance for doubtful accounts against the
portion of tenant accounts receivable which is estimated to be uncollectible.

Cash and Cash Equivalents

We consider all highly liquid debt instruments purchased with an original maturity of three months or less to
be cash equivalents. Cash and cash equivalents at December 31, 2007 and 2006 consist of demand deposits at
commercial banks and money market funds.

Real Estate

Development Properties. Land, buildings and improvements are recorded at cost. Expenditures related to the
development of real estate are carried at cost which includes capitalized carrying charges, acquisition costs and
development costs. Carrying charges, primarily interest, real estate taxes and loan acquisition costs, and direct
and indirect development costs related to buildings under construction, are capitalized as part of construction in
progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available
for occupancy. The Company capitalizes acquisition costs once the acquisition of the property becomes probable.
Prior to that time, we expense these costs as acquisition expense. During the year ended December 31, 2007,
interest in the amount of $0.1 million was capitalized on properties under development. No such amounts were
capitalized in 2006 or 2005.

Acquired Properties and Acquired Lease Intangibles. We account for real estate acquisitions pursuant to
Statement of Financial Accounting Standards (“SFAS”) No. 141, “Business Combinations.” Accordingly, we
allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible
assets and to the acquired liabilities based on their respective fair values. Identifiable intangibles include amounts
allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any.
We determine fair value based on estimated cash flow projections that utilize appropriate discount and
capitalization rates and available market information. Estimates of future cash flows are based on a number of
factors including the historical operating results, known trends and specific market and economic conditions that
may affect the property. Factors considered by management in our analysis of determining the as-if-vacant
property value include an estimate of carrying costs during the expected lease-up periods considering market
conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate
taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand
and other economic conditions. Management also estimates costs to execute similar leases including leasing
commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases
and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental
revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or
discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.

December 31, 2007

2. Summary of Significant Accounting Policies (Continued)

Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of 5
to 39 years for the buildings and improvements. Tenant improvements are depreciated using the straight-line
method over the life of the improvement or remaining term of the lease, whichever is shorter.

Impairment. We review our properties for impairment annually or whenever events or changes in
circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be
recoverable through operations. We determine whether an impairment in value has occurred by comparing the
estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of
the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the
amount by which the carrying value of the property exceeds its fair value. Management has determined that there
has been no impairment in the carrying value of our real estate assets as of December 31, 2007.

Accrued Rent and Accounts Receivable

Included in accrued rent and accounts receivable are base rents, tenant reimbursements and receivables
attributable to recording rents on a straight-line basis. An allowance for the uncollectible portion of accrued rents
and accounts receivable is determined based upon customer credit-worthiness (including expected recovery of
our claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends. As
of December 31, 2007 and 2006, we had an allowance for uncollectible accounts of $1.1 million and $0.6 million
respectively. During 2007, 2006 and 2005, we recorded bad debt expense in the amount of $0.6 million, $0.4
million and $0.1 million respectively, related to tenant receivables that we specifically identified as potentially
uncollectible based on our assessment of the tenant’s credit-worthiness. Bad debt expenses and any related
recoveries are included in property operation and maintenance expense in the consolidated statements of
operations.

Unamortized Lease Commissions and Loan Costs

Leasing commissions are amortized using the straight-line method over the terms of the related lease
agreements. Loan costs are amortized on the straight-line method over the terms of the loans, which
approximates the interest method. Costs allocated to in-place leases whose terms differ from market terms related
to acquired properties are amortized over the remaining life of the respective leases.

Prepaids and Other Assets

Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements
for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future
acquisitions.

Income Taxes

Federal—We are qualified as a real estate investment trust (“REIT”) under the Internal Revenue Code of
1986 and are therefore not subject to Federal income taxes provided we meet all conditions specified by the
Internal Revenue Code for retaining our REIT status. We believe we have continuously met these conditions
since reaching 100 shareholders in 1999 (see Note 11).

2. Summary of Significant Accounting Policies (Continued)

State—In May 2006, the State of Texas adopted House Bill 3, which modified the state’s franchise tax
structure, replacing the previous tax based on capital or earned surplus with one based on margin (often referred
to as the “Texas Margin Tax”) effective with franchise tax reports filed on or after January 1, 2008. The Texas
Margin Tax is computed by applying the applicable tax rate (1% for us) to the profit margin, which, generally,
will be determined for us as total revenue less a 30% standard deduction. Although House Bill 3 states that the
Texas Margin Tax is not an income tax, SFAS No. 109, “Accounting for Income Taxes,” applies to the Texas
Margin Tax. We have recorded a margin tax provision of $0.2 million for the Texas Margin Tax for the Year
Ended December 31, 2007.

Derivative Instruments

We have initiated a program designed to manage exposure to interest rate fluctuations by entering into
financial derivative instruments. The primary objective of this program is to comply with debt covenants on a
credit facility. We entered into an interest rate swap agreement with respect to amounts borrowed under certain
of our credit facilities, which effectively exchanges existing obligations to pay interest based on floating rates for
obligations to pay interest based on fixed LIBOR rates.

We have adopted SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as
subsequently amended by SFAS No. 138, “Accounting for Certain Derivative Instruments and Certain Hedging
Activities,” and SFAS No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging
Activities,” which require for items appropriately classified as cash flow hedges that changes in the market value
of the instrument and in the market value of the hedged item be recorded as other comprehensive income or loss
with the exception of the portion of the hedged items that are considered ineffective. The derivative instruments
are reported at fair value as other assets or other liabilities as applicable. As of December 31, 2007, we have a
$70 million dollar interest rate swap which has been designated as a cash flow hedge. The fair value of this
interest rate swap is approximately ($0.4) million and is included in accounts payable and accrued expenses in
the consolidated balance sheets. Additionally for a previous interest rate swap which was not designated as a cash
flow hedge, approximately ($0.03) million and $0.03 million are included in other expense and other income on
the consolidated statements of operations for the years ended December 31, 2007 and 2006, respectively.

Fair Value of Financial Instruments

Our financial

instruments consist primarily of cash, cash equivalents, accounts receivable, derivative
instruments, accounts and notes payable. The carrying value of cash, cash equivalents, accounts receivable and
accounts payable are representative of their respective fair values due to the short-term nature of these
instruments. The fair value of our debt obligations is representative of its carrying value based upon current rates
offered for similar types of borrowing arrangements. The fair value of interest rate swaps (used for hedging
purposes) is the estimated amount that the financial institution would receive or pay to terminate the swap
agreements at the reporting date, taking into account current interest rates and the current credit worthiness of the
swap counterparties.

Concentration of Risk

Substantially all of our revenues are obtained from office, warehouse and retail locations in the Houston,
Dallas and San Antonio, Texas metropolitan areas. We maintain cash accounts in major U.S. financial institutions.
The terms of these deposits are on demand to minimize risk. The balances of these accounts occasionally exceed the
federally insured limits, although no losses have been incurred in connection with these deposits.

2. Summary of Significant Accounting Policies (Continued)

Comprehensive Loss

We follow SFAS No. 130, “Reporting Comprehensive Income,” which establishes standards for reporting
and display of comprehensive income and its components. In October 2007 we entered into an interest rate swap
which was designated as a cash flow hedge. The fair value of this cash flow hedge was ($0.4) million at
December 31, 2007. This amount has been recorded as a reduction to minority interest and to other
comprehensive loss.

New Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48
(“FIN 48”), “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109”.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in the financial statements. The
interpretation prescribes a recognition threshold and measurement attribute for
the financial statement
recognition of a tax position taken, or expected to be taken, in a tax return. A tax position may only be
recognized in the financial statements if it is more likely than not that the tax position will be sustained upon
examination. There are also several disclosure requirements. We adopted this interpretation during the first
quarter of 2007, and it had no effect on our consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 defines
fair value, establishes a framework for measuring fair value under U.S. generally accepted accounting principles
and requires enhanced disclosures about fair value measurements. It does not require any new fair value
measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. We do not expect this pronouncement to have
a material effect on our consolidated results of operation or financial position.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities—Including an amendment of FASB Statement No. 115”. SFAS No. 159 permits entities to
choose to measure many financial instruments and certain other items at fair value. The objective is to improve
financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by
measuring related assets and liabilities differently without having to apply complex hedge accounting provisions.
SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and
interim periods within those fiscal years. We currently do not plan to measure any eligible financial assets and
liabilities at fair value under the provisions of SFAS No. 159.

In September 2007, the FASB ratified Emerging Issues Task Force (“EITF”) Issue No. 07-6, “Accounting
for the Sale of Real Estate Subject to the Requirements of FASB Statement No. 66 When the Agreement Includes
a Buy-Sell Clause,” which clarifies that a buy-sell clause, in and of itself, does not constitute a prohibited form of
continuing involvement that would preclude partial sale treatment under SFAS No. 66. EITF No. 07-6 applies
prospectively to new arrangements entered into in fiscal years beginning after December 15, 2007.

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations,” which replaces SFAS
No. 141, “ Business Combinations,” which, among other things, establishes principles and requirements for how
an acquiring entity recognizes and measures in its financial statements the identifiable assets acquired, the
liabilities assumed (including intangibles) and any noncontrolling interests in the acquired entity. SFAS
No. 141(R) applies prospectively to business combinations for which the acquisition date is on or after the
beginning of the first annual reporting period beginning on or after December 15, 2008.

2. Summary of Significant Accounting Policies (Continued)

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial
Statements, an amendment of ARB No. 51.” SFAS No. 160 amends ARB 51 to establish accounting and reporting
standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It also
amends certain of ARB 51’s consolidation procedures for consistency with the requirements of SFAS
No. 141(R). SFAS No. 160 is effective for fiscal years, and interim periods within those fiscal years, beginning
on or after December 15, 2008. We are currently evaluating what impact our adoption of SFAS No. 160 will
have on our consolidated financial statements.

3. Derivatives and Hedging

On September 28, 2007, we entered into an interest rate swap transaction which we have designated as a
cash flow hedge. The effective date of the swap transaction is October 1, 2007, has a total notional amount of $70
million, and fixes the swap rate at 4.77% plus the LIBOR margin (see Note 9) through October 1, 2008. The
purpose of this swap is to mitigate the risk of future fluctuations in interest rates on our variable rate debt. We
have determined that this swap is highly effective in offsetting future variable interest cash flows on variable rate
debt.

As of December 31, 2007, the balance in Accumulated Other Comprehensive Loss relating to derivatives
was $0.2 million. Within the next 12 months the balance in Accumulated Other Comprehensive Loss is expected
to be amortized to Interest Expense.

On September 28, 2007, in conjunction with the execution of the $70 million interest rate swap transaction,
we terminated an interest rate swap transaction that was initiated on March 16, 2006. This swap transaction had a
total notional amount of $30 million, was at a fixed rate of 5.09% plus the LIBOR margin (see Note 9) and was
set to mature on March 11, 2008. As a result of this termination ($0.03) million is included in other income in our
consolidated statements of operations.

4. Real Estate

During 2005, we acquired from an unrelated party one multi-tenant office building comprising
approximately 106,169 square feet of gross leasable area. The property was acquired for cash in the amount of
approximately $5.5 million plus closing costs.

During 2005, we acquired from an unrelated party one multi-tenant office building comprising
approximately 125,874 square feet of gross leasable area. The property was acquired for cash in the amount of
approximately $8.0 million plus closing costs.

During 2005, we acquired from an unrelated party one multi-tenant office building comprising
approximately 253,981 square feet of gross leasable area. The property was acquired for cash in the amount of
approximately $17.0 million plus closing costs.

During 2006, we sold Northwest Place II, a 27,974 square foot office/warehouse building located in
Houston, Texas for a sales price of $1.2 million. A gain of $0.2 million was generated from this sale, which is
reflected in our consolidated financial statements for the year ended December 31, 2006. It is anticipated that the
funds received from this sale will be used for future acquisitions and/or capital improvements to existing
properties. It was determined that “discontinued operations” classification was not required due to the
immateriality of this property to our overall results.

4. Real Estate (Continued)

During 2007, we sold a 2.4 acre parcel of vacant land adjacent to our South Shaver retail property located in
Houston, Texas for a sales price of $0.3 million. A gain of $0.1 million was generated from this sale, which is
reflected in our consolidated financial statements for the three and nine months ended September 30, 2007. It is
anticipated that the funds received from this sale will be used for future acquisitions and/or capital improvements
to existing properties

During 2007, we acquired from an unrelated party one office building under development. The property was
acquired for cash in the amount of approximately $8.2 million plus closing costs. Upon completion we expect to
have invested approximately $10.0 million in the building which will contain approximately 33,400 square feet
of gross leaseable area.

At December 31, 2007, we owned 37 commercial properties in the Houston, Dallas, San Antonio and

Phoenix comprising approximately 3.1 million square feet of gross leasable area.

5. Note Receivable

In January 2003, we partially financed the sale of a property we had previously sold and for which we had
taken a note receivable of $0.4 million as part of the consideration. We advanced $0.3 million and renewed and
extended the balance of $0.4 million still due from the original sale.

The original principal amount of the note receivable, dated January 10, 2003, is $0.7 million. The note had
monthly installments of $6,382, including interest at 7% per annum, for the first two years, and thereafter
monthly installments of $7,489 with interest at 10% per annum until maturity on January 10, 2018.

This note was paid in full on August 30, 2007.

6. Accrued Rent and Accounts Receivable, Net

As of December 31, 2007, we have two active loans which are described below:

Revolving Credit Facility

We have a revolving credit facility with a consortium of banks. The credit facility is secured by a pledge of
the partnership interests in Whitestone REIT Operating Partnership III LP (“WROP III”), a wholly owned
subsidiary of the Operating Partnership that was formed to hold title to the properties comprising the borrowing
base pool for the facility. At December 31, 2007, WROP III owns 35 properties.

As of December 31, 2007 and December 31, 2006, the balance outstanding under the credit facility was
$73.5 million and $61.2 million, respectively, and the availability to draw was $1.5 million and $13.8 million,
respectively.

Outstanding amounts under the credit facility accrue interest computed (at our option) at either the LIBOR
or the Alternative Base Rate on the basis of a 360 day year, plus the applicable margin as determined from the
following table:

2.40%
2.15%
1.90%

1.150%
1.025%
1.000%

The Alternative Base Rate is a floating rate equal to the higher of the bank’s base rate or the Federal Funds
Rate plus 0.5%. LIBOR Rate loans will be available in one, two, three or six month periods, with a maximum of
nine contracts at any time. The effective interest rate as of December 31, 2007 was 7.03% per annum.

Interest only is payable monthly under the loan with the total amount of principal due at maturity on
March 11, 2008. The loan may be prepaid at any time in part or in whole, provided that the credit facility is not in
default. If LIBOR pricing is elected, there is a prepayment penalty based on a “make-whole” calculation for all
costs associated with prepaying a LIBOR borrowing.

The revolving credit facility is supported by a pool of eligible properties referred to as the borrowing base

pool. The borrowing base pool must meet the following criteria:

• We will provide a negative pledge on the borrowing base pool and may not provide a negative pledge

of the borrowing base pool to any other lender.

F-15

WHITESTONE REIT AND SUBSIDIARY

Notes to Consolidated Financial Statements—(Continued)

December 31, 2007

9. Debt (Continued)

• The properties must be free of all liens, unless otherwise permitted.

• All eligible properties must be retail, warehouse, or office properties, must be free and clear of material

environmental concerns and must be in good repair.

• The aggregate physical occupancy of the borrowing base pool must remain above 80% at all times.

• No property may comprise more than 15% of the value of the borrowing base pool with the exception

of Corporate Park Northwest, which is allowed into the borrowing base pool.

• The borrowing base pool must at all times be comprised of at least ten properties.

• The borrowing base pool properties may not contain development or redevelopment projects.

Properties can be added to and removed from the borrowing base pool at any time provided no defaults
would occur as a result of the removal. If a property does not meet the criteria of an eligible property and we
want to include it in the borrowing base pool, a majority vote of the bank consortium is required for inclusion in
the borrowing base pool.

Covenants, tested quarterly, relative to the borrowing base pool are as follows:

• We will not permit any liens on the properties in the borrowing base pool unless otherwise permitted.

• The ratio of aggregate net operating income from the borrowing base pool to debt service shall at all
times exceed 1.5 to 1.0. For any quarter, debt service shall be equal to the average loan balance for the
past quarter times an interest rate which is the greater of (a) the then current annual yield on ten year
United States Treasury notes over 25 years plus 2%; (b) a 6.5% constant; or (c) the actual interest rate
for the facility.

• The ratio of the value of the borrowing base pool to total funded loan balance must always exceed 1.67
to 1.00. The value of the borrowing base pool is defined as aggregate net operating income for the
preceding four quarters, less a $0.15 per square foot per annum capital expenditure reserve, divided by
a 9.25% capitalization rate.

Other covenants, tested quarterly, relative to us are as follows:

• We will not permit our total indebtedness to exceed 60% of the fair market value of our real estate
assets at the end of any quarter. Total indebtedness is defined as all our liabilities, including this facility
and all other secured and unsecured debt, including letters of credit and guarantees. Fair market value
of real estate assets is defined as aggregate net operating income for the preceding four quarters, less a
$0.15 per square foot per annum capital expenditure reserve, divided by a 9.25% capitalization rate.

• The ratio of consolidated rolling four-quarter earnings before interest, income tax, depreciation and
amortization expenses to total interest expense, including capitalized interest, shall not be less than 2.0
to 1.0.

• The ratio of consolidated earnings before interest, income tax, depreciation and amortization expenses
to total interest expense, including capitalized interest, principal amortization, capital expenditures and
preferred stock dividends shall not be less than 1.5 to 1.0. Capital expenditures shall be deemed to be
$0.15 per square foot per annum.

9. Debt (Continued)

• The ratio of secured debt to fair market value of real estate assets shall not be greater than 40%.

• The ratio of declared dividends to funds from operations shall not be greater than 95%. This has been

amended to 105% through March 11, 2008,

• The ratio of development assets to fair market value of real estate assets shall not be greater than 20%.

• We must maintain our status as a REIT for income tax purposes.

• Total other investments shall not exceed 30% of total asset value. Other investments shall include
investments in joint ventures, unimproved land, marketable securities and mortgage notes receivable.
Additionally, the preceding investment categories shall not comprise greater than 30%, 15%, 10% and
20%, respectively, of total other investments.

• We must maintain a consolidated tangible net worth of not less than $30 million plus 75% of the value
of stock and OP units issued in conjunction with an offering or with the acquisition of an asset or stock.
Consolidated tangible net worth is defined as shareholders equity less intangible assets.

On March 11, 2008, we amended our Revolving Credit Facility and extended the maturity through

October 1, 2008. The amendment is filed with this Form 10-K as exhibit 10.28. The key amendments were:

• The minimum ratio of consolidated rolling four-quarter earnings before interest,

income tax,
depreciation and amortization expenses to total interest expense, including capitalized interest, was
reduced from a ratio of 2.0 to 1.0 to a ratio of 1.55 to 1.0.

• The minimum ratio of consolidated earnings before interest, income tax, depreciation and amortization
including capitalized interest, principal amortization, capital
expenses to total
expenditures and preferred stock dividends was lowered from a ratio of 1.50 to 1.0 to a ratio of 1.40
to 1.0.

interest expense,

• Declared or subsequently paid dividends will not be allowed to increase above the fourth quarter 2007
level. If the number of shares issued and outstanding decrease, then the dividend payout must decrease
proportionately.

• Outstanding amounts under the credit facility accrue interest (at our option) at either the LIBOR or the

Applicable Base Rate on the basis of a 360 day year, plus the applicable margin as shown below:

Mortgage Loan on Windsor Park Centre

On March 1, 2007, we obtained a $10 million loan to pay off the loan obtained upon the acquisition of the
Windsor Park property and to provide funds for future acquisitions. The mortgage loan is secured by the Windsor
Park property which is owned by Whitestone REIT Operating Company IV LLC (“WROC IV”), a wholly owned
subsidiary of the Operating Partnership that was formed to hold title to the Windsor Park property. On March 1,
2007, we conveyed ownership of the Windsor Park property from the Operating Partnership to WROC IV in
order to secure the $10 million mortgage loan.

The note is payable in equal monthly installments of principal and interest of $60,212, with interest at the
rate of 6.04% per annum. The balance of the note is payable in full on March 1, 2014. The loan balance is
approximately $9.9 million at December 31, 2007.

Other

On January 25, 2008 we entered into a $6.4 million term loan agreement with KeyBank. The term loan is
secured by a pledge of the partnership interests in WROP III, and Whitestone Pima Norte LLC (“WPN”), a
wholly owned subsidiary of the Operating Partnership that was formed to hold title to our Pima Norte property
that was purchased in October 2007. At December 31, 2007, WROP III owns 35 properties and WPN owns 1
property.

Outstanding amounts under the term loan accrue interest computed at the LIBOR Rate on the basis of a 360
day year, plus 2%. Interest only is payable monthly under the loan with the total amount of principal due at
maturity in July, 2009. The covenants of this agreement mirror those in our $75 million revolving credit
agreement and are described above. This term loan agreement is filed with this Form 10-K as exhibit 10.29.

We expect that we will have substantially leased this property by end of 2008 and plan to obtain long term

financing on this property at the maturity of the revolving credit facility.

10. Earnings Per Share

Basic earnings per share is computed using net income to common shareholders and the weighted average
number of common shares outstanding. Diluted earnings per share reflects common shares issuable from the
assumed conversion of OP Units convertible into common shares. Only those items that have a dilutive impact
on basic earnings per share are included in the diluted earnings per share. Accordingly, excluded from the
earnings per share calculation for each of the years ended December 31, 2007, 2006 and 2005, are 5,808,337 OP
units as their inclusion would be anti-dilutive.

11. Federal Income Taxes

Federal income taxes are not provided because we intend to and believe we qualify as a REIT under the
provisions of the Internal Revenue Code. Our shareholders include their proportionate taxable income in their
individual tax returns. As a REIT, we must distribute at least 90% of its ordinary taxable income to our
shareholders and meet certain income sources and investment restriction requirements. In addition, REITs are
subject to a number of organizational and operational requirements. If we fail to qualify as a REIT in any taxable
year, we will be subject to federal income tax (including any applicable alternative minimum tax) on our taxable
income at regular corporate tax rates.

Taxable income differs from net income for financial reporting purposes principally due to differences in

the timing of recognition of interest, real estate taxes, depreciation and rental revenue.

For Federal income tax purposes, the cash dividends distributed to shareholders are characterized as follows

for the years ended December 31:

12. Related Party Transactions

Prior to October 2006, our day-to-day operations and portfolio of properties were managed by our former
External Manager through property management and advisory agreements. Mr. Hartman, our former President,
Secretary, Chief Executive Officer, and Chairman of the Board, is the sole limited partner of our former External
Manager, as well as the President, Secretary, sole trustee and sole shareholder of the general partner of the
External Manager.

Mr. Hartman was removed by our Board as our President, Secretary, and Chief Executive Officer on

October 2, 2006, and he resigned from our Board on October 27, 2006.

In October 2006, our Board terminated for cause our property management agreement with our former
External Manager. Our former External Manager turned over all property management functions to us on
November 14, 2006.

In addition, our Board elected not to renew our advisory agreement, dated August 31, 2004, with our former
External Manager. This agreement had been extended on a month-to-month basis and ultimately expired on
September 30, 2006.

Transactions between us, our former External Manager, and Mr. Hartman are considered related party

transactions and are discussed in the following paragraphs.

12. Related Party Transactions (Continued)

In January 1999, we entered into a property management agreement with our former External Manager.
Effective September 1, 2004, this agreement was amended and restated. Prior to September 1, 2004, in
consideration for supervising the management and performing various day-to-day affairs, we paid our former
External Manager a management fee of 5% and a partnership management fee of 1% based on effective gross
revenues from the properties, as defined in the agreement. After September 1, 2004, we paid our former External
Manager property management fees in an amount not to exceed the fees customarily charged in arm’s length
transactions by others rendering similar services in the same geographic area, as determined by a survey of
brokers and agents in that area. These fees have ranged between approximately 2% and 4% of gross revenues (as
defined in the amended and restated agreement) for the management of office buildings and approximately 5% of
gross revenues for the management of retail and warehouse properties.

Effective September 1, 2004, we entered into an advisory agreement with our former External Manager
which provided that we pay our former External Manager a quarterly fee of one-fourth of .25% of gross asset
value (as defined in the advisory agreement) for asset management services. In addition, the advisory agreement
provided for the payment of a deferred performance fee, payable in certain events, including termination of the
advisory agreement, based upon appreciation in the value of certain of our real estate assets. The advisory
agreement expired by its terms on September 30, 2006.

We incurred total management, partnership and asset management fees of $1.5 million and $1.4 million,
under the advisory and management agreements for the years ended December 31, 2006 and 2005, respectively.
We incurred no such fee for the year ended December 31, 2007. No management fees were payable at
December 31, 2007 or 2006. We have not accrued any deferred performance fees, as we believe the amount of
these fees, if any are owing, cannot be determined with reasonable certainty at this time.

In consideration of leasing the properties, we historically paid our former External Manager leasing
commissions for leases originated by our former External Manager and for expansions and renewals of existing
leases. We incurred total leasing commissions to our former External Manager of $0.9 million and $1.6 million
for the years ended December 31, 2006 and 2005, respectively. No such fees were incurred for the year ended
December 31, 2007. No such amounts were payable at December 31, 2007 or 2006.

In connection with our public offering described in Note 13, we have reimbursed our former External
Manager up to 2.5% of the gross selling price of all common shares sold for organization and offering expenses
(excluding selling commissions and a dealer manager fee) incurred by our former External Manager on our
behalf. We have paid our dealer manager, through our former External Manager by agreement between them, a
fee of up to 2.5% of the gross selling price of all common shares sold in the offering. We incurred total fees of
$0.5 million and $0.9 million for the years ended December 31, 2006 and 2005, respectively. No such fees were
incurred for the year ended December 31, 2007. These fees have been treated as offering costs and netted against
the proceeds from the sale of common shares. On October 2, 2006, our Board elected to terminate the public
offering described in Note 13.

Also in connection with our public offering described in Note 13, our former External Manager has
historically received an acquisition fee equal to 2% of the gross selling price of all common shares sold for
services in connection with the selection, purchase, development or construction of properties for us. The
advisory agreement expired by its terms on September 30, 2006. On September 30, 2006, $0.2 million of
acquisition fees paid to our former External Manager had been capitalized and not yet allocated to the purchase

price of a property. In accordance with the advisory agreement, our former External Manager is obligated to
reimburse us for any acquisition fee that has not been allocated to the purchase price of our properties as
provided for in our declaration of trust. A letter demanding payment was sent to our former External Manager on
December 21, 2006, and $0.2 million is included in accrued rent and accounts receivables on our consolidated
balance sheet at December 31, 2007 as reclassified from December 31, 2006 as described in Note 2—
Reclassification.

We incurred total acquisition fees to our former External Manager of $0.2 million and $0.4 million for the
years ended December 31, 2006 and 2005, respectively. No such fees were incurred for the year ended
December 31, 2007. No such amounts were payable at December 31, 2007 or December 31, 2006.

Our former External Manager was billed $0.1 million, $0.2 million and $0.1 million for office space for the
years ended December 2007, 2006 and 2005, respectively. These amounts are included in rental income in our
consolidated statements of operations.

Mr. Hartman our former President, Secretary, Chief Executive Officer, and Chairman was owed $0.04
million in dividends payable on his common shares at December 31, 2007 and December 31, 2006. Mr. Hartman
owned 2.9% of our issued and outstanding common shares as of December 31, 2007 and December 31, 2006.

13. Shareholders’ Equity

Under our declaration of trust, we have authority to issue 400 million common shares of beneficial interest,

$0.001 par value per share, and 50 million preferred shares of beneficial interest, $0.001 par value per share.

On September 15, 2004, our Registration Statement on Form S-11, with respect to our public offering of up
to 10 million common shares of beneficial interest offered at a price of $10 per share was declared effective
under the Securities Act of 1933. The Registration Statement also covered up to 1 million shares available
pursuant to our dividend reinvestment plan offered at a price of $9.50 per share. The shares were offered to
investors on a best efforts basis. Post-Effective Amendments No. 1, 2 and 3 to the Registration Statement were
declared effective by the SEC on June 27, 2005, March 9, 2006 and May 3, 2006, respectively.

On October 2, 2006, our Board terminated the public offering. On March 27, 2007, we gave the required ten
day notice to participants informing them that we intend to terminate our dividend reinvestment plan. As a result,
our dividend reinvestment plan terminated on April 6, 2007.

As of December 31, 2007, 2.8 million shares had been issued pursuant to our public offering with net
offering proceeds received of $24.6 million. An additional 165,000 shares had been issued pursuant to the
dividend reinvestment plan in lieu of dividends totaling $1.6 million. Shareholders that received shares pursuant
to our dividend reinvestment plan on or after October 2, 2006 may have rescission rights.

All net proceeds of our public offering were contributed to the Operating Partnership in exchange for OP
Units. The Operating Partnership used the proceeds to acquire additional properties and for general working
capital. In accordance with the Operating Partnership’s Agreement of Limited Partnership, in exchange for the
contribution of net proceeds from sales of stock, we received an equivalent number of OP Units as shares of
stock that are sold.

13. Shareholders’ Equity (Continued)

At December 31, 2007 and December 31, 2006, Mr. Hartman owned 2.9% of our outstanding shares. At

December 31, 2007 and December 31, 2006, our Board collectively owned 2.6% of our outstanding shares.

Operating Partnership Units

Substantially all of our business is conducted through the Operating Partnership. We are the sole general
partner of the Operating Partnership. As of December 31, 2007, we owned a 62.4% interest in the Operating
Partnership.

Limited partners in the Operating Partnership holding OP Units have the right to convert their OP Units into
common shares at a ratio of one OP Unit for one common share. Distributions to OP Unit holders are paid at the
same rate per unit as dividends per share of Whitestone. Subject to certain restrictions, OP Units are not
convertible into common shares until the later of one year after acquisition or an initial public offering of the
common shares. As of December 31, 2007 and December 31, 2006, there were 15,448,118 and 15,421,212 OP
Units outstanding, respectively. We owned 9,639,781 and 9,612,875 OP Units as of December 31, 2007 and
December 31, 2006, respectively. The balance of the OP Units is owned by third parties, including Mr. Hartman
and certain trustees. Our weighted-average share ownership in the Operating Partnership was approximately
62.40%, 61.53% and 56.44% for the years ended December 31, 2007, 2006 and 2005, respectively. At
December 31, 2007 and December 31, 2006, Mr. Hartman owned 6.9% of the Operating Partnership’s
outstanding units. At December 31, 2007 and December 31, 2006, our Board collectively owned 0.4% of the
Operating Partnership’s outstanding units.

15. Commitments and Contingencies

The nature of our business exposes us to the risk of lawsuits for damages or penalties relating to, among

other things, breach of contract and employment disputes. We are currently involved in the following litigation:

Hartman Commercial Properties REIT and Hartman REIT Operating Partnership, L.P. v. Allen R. Hartman
and Hartman Management, L.P., in the 333rd Judicial District Court of Harris County, Texas

In October 2006, we terminated our Chief Executive Officer, Allen R. Hartman, and our former manager
and advisor, Hartman Management, L.P. The same day, we filed this lawsuit seeking damages for breach of
contract, fraudulent inducement, and breach of fiduciary duties. Our new management approached Mr. Hartman
about cooperatively turning over operations of the company but Mr. Hartman ousted them from his offices. We
then sought an emergency court order requiring Mr. Hartman to turn over control to new management.
Mr. Hartman opposed this legal relief. The court issued an order requiring him to turn over control of the
company.

As part of the change from Mr. Hartman to new management, the company asked Mr. Hartman to agree to a
timeline for turning over specific operations and bank accounts. Mr. Hartman refused, so we had to file another
request with the court to require Mr. Hartman’s compliance. Only after we filed the request with the court did
Mr. Hartman relent and agree to a turnover timeline. During the turnover process, however, Mr. Hartman denied
the company access to its own books and records and we had to go back to court to enforce the previously
entered order that turned over the company to present management.

In November 2006, Mr. Hartman and Hartman Management filed a counterclaim against us, the individual
members of our Board, our Chief Operating Officer, John J. Dee, and our prior outside law firm and one of its
partners. The counterclaims claimed that we had breached our contracts with Mr. Hartman and Hartman

December 31, 2007

15. Commitments and Contingencies (Continued)

Managment and committed tortious interference with contract, intentional infliction of emotional distress, and
conspiracy. We prepared defenses to these counterclaims.

Subsequent to our preparations, Mr. Hartman and Hartman Management retained new attorneys. The new
attorneys filed amended counterclaims on behalf of Mr. Hartman and Hartman Management and dropped the
claims against the individual members of our Board, with the exception of our Chairman, James C. Mastandrea.
The amended counterclaims now also alleged negligence, fraud, and breach of fiduciary duty. We proceeded to
prepare defenses in response to these amended counterclaims.

Mr. Hartman then hired a different set of attorneys and amended the counterclaims again to drop all of the
claims against our prior outside law firm and its partner, many of the claims against us, and all of the claims,
without prejudice, against Mr. Mastandrea and Mr. Dee. The amended counterclaim now asserts claims against
us only for breach of contract and alleges that we owe Mr. Hartman and Hartman Management a fee for the
termination of an advisory agreement. In communications to shareholders, Mr. Hartman represented that the
termination fee, as calculated by him, could be in excess of $20 million.

We filed a motion for summary judgment on Mr. Hartman’s and Hartman Management’s claims that we
breached our contracts with Hartman Management. On March 25, 2008, the court granted our motion, in part,
and stated that the termination fee allegedly due under the advisory agreement was subject to the cap on total
operating expenses described in Section IV.D.1 of the North American Securities Administrators Association’s
Statement of Policy on Real Estate Investment Trusts.

The parties have each submitted reports of experts as to the amount of the fee due for the termination of the
advisory agreement, other fees and expense reimbursements, and damages. Discovery is being conducted for this
case, which has a court date of May 19, 2008. Before the court’s March 25, 2008 ruling that capped the advisory
agreement termination fee, Mr. Hartman and Hartman Management claimed damages of either $4.8 million or
$6.4 million plus prejudgment interest and attorneys’ fees; Whitestone maintains that no amounts are due for
fees, expenses and damages and we intend to vigorously defend against those claims and vigorously prosecute
our affirmative claims.

Hartman Commercial Properties REIT v. Allen R. Hartman, et al; in the United States District Court for the
Southern District of Texas

In November 2006, we learned that Mr. Hartman was soliciting written consents from shareholders and had
sought approval from the SEC to distribute a consent solicitation to replace our Board. We asked Mr. Hartman to
refrain from distributing the consent solicitation until the false and misleading information was removed. He
refused, so we initiated this lawsuit and sought a Temporary Injunction to stop Mr. Hartman from distributing the
consent solicitation.

Mr. Hartman and Hartman Management filed a counterclaim, alleging that certain changes to our bylaws
and declaration of trust were invalid and that their enactment was a breach of fiduciary duty. Mr. Hartman sought
a Temporary Injunction to prevent these changes from taking effect. These changes, among other things,
staggered the terms of our Board members over three years, required a two-thirds vote of the outstanding
common shares to remove a Board member and provided that our secretary may call a special meeting of
shareholders only on the written request of a majority of outstanding common shares.

15. Commitments and Contingencies (Continued)

With Mr. Hartman’s encouragement, a group of shareholders filed a motion to intervene and bring claims
against us in this lawsuit. The interveners’ claims were similar to the counterclaims filed by Mr. Hartman and
Hartman Management. The shareholders eventually dismissed their request to intervene with prejudice, though
not before we were required to prepare defenses to their claims and move to block their intervention.

The court ordered Mr. Hartman to refrain from distributing the consent solicitation while the parties exchanged
discovery and took depositions in preparation for a full hearing on the competing requests for Temporary
Injunctions. On April 6, 2007, the court ruled in our favor and Mr. Hartman was ordered not to distribute the
consent solicitation. Also on April 6, 2007, the court denied Mr. Hartman’s request for a Temporary Injunction
challenging the changes to our bylaws and declaration of trust and the court upheld the changes to our bylaws and
declaration of trust as valid exercises of the Board’s powers. The court also granted our Motion to Dismiss,
dismissing many of Mr. Hartman’s and Hartman Management’s remaining claims against us.

Mr. Hartman appealed the court’s April 6, 2007 rulings to the Fifth Circuit Court of Appeals. After
considering the parties’ written briefs and oral arguments held in New Orleans, the Fifth Circuit upheld the lower
court’s rulings. We still have securities law claims against Mr. Hartman and Hartman Management and his
remaining counterclaims are still pending against us, though no monetary damages are being sought by either
side. Trial is currently set for November 2008.

Other

We are a participant in various other legal proceedings and claims that arise in the ordinary course of our
business. These matters are generally covered by insurance. While the resolution of these matters cannot be
predicted with certainty, we believe that the final outcome of these matters will not have a material effect on our
financial position, results of operations, or cash flows.

16. Segment Information

Our management historically has not differentiated by property types and therefore does not present

segment information.

18. Subsequent Events

Pima Norte Loan

On January 25, 2008 we entered into a $6.4 million term loan agreement with KeyBank. The term loan is
secured by a pledge of the partnership interests in WROP III, and Whitestone Pima Norte LLC (“WPN”), a
wholly owned subsidiary of the Operating Partnership that was formed to hold title to our Pima Norte property
that was purchased in October 2007. At December 31, 2007, WROP III owns 35 properties and WPN owns one
property.

Outstanding amounts under the term loan accrue interest computed at the LIBOR Rate on the basis of a 360
day year, plus 2%. Interest only is payable monthly under the loan with the total amount of principal due at
maturity in July, 2009. The covenants of this agreement mirror those in our $75 million revolving credit
agreement and are described in Note 9. This term loan agreement is filed with this Form 10-K as exhibit 10.29.

We expect that we will have substantially leased this property by end of 2008 and plan to obtain long term

financing on this property at the maturity of the revolving credit facility.

Extension of Maturity Date of our Revolving Credit Facility

On March 11, 2008, we amended our Revolving Credit Facility and extended the maturity through

October 1, 2008. The amendment is filed with this Form 10-K as exhibit 10.28. The key amendments were:

• The minimum ratio of consolidated rolling four-quarter earnings before interest,

income tax,
depreciation and amortization expenses to total interest expense, including capitalized interest, was
reduced from a ratio of 2.0 to 1.0 to a ratio of 1.55 to 1.0.

• The minimum ratio of consolidated earnings before interest, income tax, depreciation and amortization
expenses to total
including capitalized interest, principal amortization, capital
expenditures and preferred stock dividends was lowered from a ratio of 1.50 to 1.0 to a ratio of 1.40
to 1.0.

• Declared or subsequently paid dividends will not be allowed to increase above the fourth quarter 2007
level. If the number of shares issued and outstanding decrease, then the dividend payout must decrease
proportionately.

• Outstanding amounts under the credit facility accrue interest (at our option) at either the LIBOR or the

Applicable Base Rate on the basis of a 360 day year, plus the applicable margin as shown below:
